FIELD OF THE INVENTION
[0001] The present invention relates to a mosquito attracting and killing device. Specifically, the present invention relates to an improved mosquito attracting and killing device for indoor use. The present invention further relates to Kairomone based mosquito attracting device wherein Kairomone works as an emulator emulating human prey for mosquitoes.

BACKGROUND OF THE INVENTION
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] Mosquitoes are insects that have been around for more than 30million years. There are over 3,500 species of mosquito throughout the world. But it is only the female of the species which bites as she searches out nourishment for her eggs. They are known to cause harmful diseases like Malaria, Chikungunya and Dengue by transmitting disease causing pathogens into humans. Mosquitoes have a behavioral habit of being attracted by the smell of host animals and heat or carbon dioxide generated from the host animals. So in order to trap the female mosquito the device needs to act like human source of food. Mosquitoes locate hosts through a combination of chemicals characteristic of the hosts. The mosquito cues are skin emanation smell, human breathe out of CO2, human body movements and reflections and body heat. It is believed that the volatiles emanating from the human host are responsible for the attractant. These volatiles contain 300-400 compounds and originate from either the secretions of skin glands, or the decomposition of the skin microflora, or both. The mosquitoes use their olfactory structures to detect the attractant from as far away as 90 meters.
[0004] Generally, there are several ways to control mosquitoes, for example, chemical controlling using a mosquito coil or the like; biological controlling using loaches or the like; physical controlling which attracts mosquitoes by means of a mosquito-attracting lamp, carbon dioxide or the like and then applies high voltage; and environmental controlling which improves the surrounding environment such that mosquitoes larvae cannot proliferate (for instance, removing water pools). Many mosquito killing products are electronic and attract mosquitoes by emitting ultraviolet (UV) light and then trap and kill the mosquito using adhesive and electric shock.
[0005] The present invention is based on human skin emanation Kairomone which is dissipated from the device by means of evaporation. Evaporation apparatus for liquid Kairomone is the key to the effectiveness of human target emulating mosquito traps. The design of evaporation apparatus decides the area of spread and intensity of the vaporised liquid in a specified area in which mosquitoes have to be trapped, which in turn will affect the percentage of mosquitoes trapped in that specified area. Most of these traps trap and kill the mosquitoes using a suction fan that sucks the mosquitoes into traps attached just beneath the fan. This trapping mechanism works in cohesion with the rest of the trap that attracts the mosquitoes, namely the liquid Kairomone and the evaporation apparatus that vaporizes the liquid to spread to the entire specified area. Some traps may have additional mechanisms such as human heat emulation, human breath emulation (as CO2 emission) and simple light source attraction. A simple design found in most existing traps, with the trapping apparatus and evaporation apparatus aligned along a central vertical axis may not be effective in terms of spread of the Kairomone vapour since the suction action of the fan will end up sucking most of the Kairomone vapour. In this case the evaporation is in fan suction area and hence gets forced air dissipation and mosquito is unable to identify the source to come for further investigation of the human prey.
[0006] Therefore, it is desirable to provide a mosquito killer, which can overcome the above-mentioned shortcomings. The present invention is an improved model of the evaporation apparatus that can be modified for existing traps.
[0007] There is, therefore, a need to develop an improved Kairomone based device for attracting and killing mosquitoes, which can overcome deficiencies associated with the known arts.

[0050] Various terms as used herein are shown below. To the extent a term used in a claim is not defined below, it should be given the broadest definition persons in the pertinent art have given that term as reflected in printed publications and issued patents at the time of filing.
[0051] The present invention relates to a mosquito attracting and killing device. Specifically, the present invention relates to an improved Kairomone based mosquito attracting device wherein Kairomone works as an emulator emulating human pray for mosquitoes.
[0052] This invention is an improved model of the existing evaporation apparatus. Most of these traps trap and kill the mosquitoes using a suction fan that sucks the mosquitoes into traps attached just beneath the fan. This trapping mechanism works in cohesion with the rest of the trap that attracts the mosquitoes, namely the Kairomone and the evaporation apparatus that vaporizes the kariomone to spread to the entire specified area. A simple design found in most existing traps consists of a trapping apparatus and evaporation apparatus aligned along a central vertical axis. Such an arrangement is not very effective in terms of spread of the Kairomone vapour since the suction action of the fan will end up sucking most of the Kairomone vapour. As the Kairomone dissipation point gets closer to the suction point of the device the dissipation pattern gets distorted and source point is unidentified. So the Kairomone needs to be placed at a height w.r.t the suction point so the dissipation happens uniformly.
[0053] To overcome the existing problem, the present invention discloses an improved kairomone based device for attracting and killing mosquitoes as shown in Figure 1. In one embodiment, the present invention discloses a Kairomone based mosquito attracting and killing device for indoor use, which consists of Kairomone evaporation apparatus (122), a suction fan (110) and collecting tray (112), all assembled inside the main unit (100); wherein the kairomone evaporation device (122) is placed away from the line of axis of the suction fan (110), at a certain height and angle. The kairomone dissipation point (104) is at a certain height (in terms of height ratio with respect to the height of the device) to achieve proper isolation from the suction effect and also for the easy removal/replacement of the kairomone container. Figure 1 depicts two kairomone containers (122) placed at a particular height and angle with respect to the vertical axis of suction fan. Figure 2 depicts one kairomone device (122), wherein the placement of the kairomone evaporator at an angle and height from the suction axis, represents face and forehead. Figure 3 represents Isometric view of the mosquito attracting and killing device for indoor use, wherein LED holder (116) acts in addition to the kairomone vapours to attract mosquitoes. The main unit (100) has kairomone evaporation device (122), placed at an angle and height with respect to the suction zone, the suction fan (110) has a collecting tray (112) at the bottom and mosquitoes enter the collecting tray/ trapper via the inlet cone (108).
[0054] In an embodiment of the invention, Kairomone refers to a chemical substance emitted by
an organism and detected by another of a different species. Kairomones, are utilized as attractants to lure a pest species. The term “Kairomone” may also refer to pheromone (communication chemicals used within a species). The terms “Kairomone” and “Pheromone” may be used interchangeably in this invention.
[0055] In another embodiment of the invention, the term “evaporation” may be used interchangeably with the term “dissipation” and the term “device” may be used interchangeably with the term “apparatus”.
[0056] In one embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes for indoor use, which can which can be used in any small enclosed areas like inside home, office, hotel rooms, hospital rooms and the like. Indoor areas can be defined as small enclosed areas like inside homes, hotel rooms, hospital rooms and the like.
[0057] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, which reduces the effect of the suction fan in the trap on the Kairomone vapour by increasing the effective area of evaporation and ease of spread.
[0058] In yet another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein Kairomone and its evaporation apparatus are away from line of axis of the suction fan.
[0059] In a preferred embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein Kairomone and its evaporation apparatus are moved away from the line of axis of suction fan, to achieve proper isolation from the suction effect.
[0060] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein the central offset is greater than the suction area.
[0061] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes wherein kariomone placement in the device mimics the position of sensory organs relevant to mosquitoes.
[0062] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes wherein placement of kairomone evaporation device is according to the different parts of human being emulated such as face, hands, feet, leg and other areas of body.
[0063] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein height of the Kairomone evaporation device from the suction plane is in the range of 100 mm to 2000 mm.
[0064] In another embodiment, height of the Kairomone evaporation apparatus w.r.t to the total device height can vary according to which part of human body the apparatus is emulating.
[0065] The area from nose mouth distance to sweating skin areas in humans attracts most of the mosquitoes. The indoor device can emulate a forehead or a face by changing angle and height of pheromone diffuser mounting point. This improves performance by holding the diffused pheromone for a bit of more time (response time of mosquito to enter the trap zone) and spreading the kairomone evenly. To improve the spread of kairomone, one or more pheromone diffusing points can be added to existing one.
[0066] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein height of the Kairomone evaporation device placement w.r.t to the total device height can be in the range of 1:3 to 1:7.
[0067] In a preferred embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein height of the Kairomone evaporation apparatus w.r.t to the device height is 1:4 when emulating facial parts like mouth, nose forehead.
[0068] In another preferred embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein height of the Kairomone evaporation apparatus w.r.t to the device height is 1:4 when emulating body parts like hands, legs, feet.
[0069] According to the present invention, the mouth nose and sweating area of skin is emulated by the device. The distance of nose mouth to sweating skin areas (below knee, arm pits near groin areas) are ratio wise replicated in the device by its height of device to height of kairomone evaporation point.
[0070] Another aspect of the present invention relates to the slight elevated, position of the Kairomone mounting point which is positioned at an angle to the vertical axis to achieve the desired height of isolation and easy removal.
[0071] In an embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein Kairomone evaporation apparatus is placed at an angle with respect to the vertical axis of suction fan.
[0072] In an embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein Kairomone evaporation device is placed in the diffusion zone at an angle selected from 15 to 60 degree with respect to the vertical axis of suction fan.
[0073] By avoiding angles greater than 60 degrees from the vertical axis of suction, the efficiency of the device can be maintained. So the efficient pheromone diffusion zone or angle of pheromone placement w.r.t vertical is 15 to 45 degrees or 15 to 60 degrees based on size and shape (as depicted in Table 1 and Figures 4 and 5). The height and the vertical angle w.r.t to fan axis vary proportionally and form an inverted cone. The height increases as the angle reduces. (Figure 4 and 5).
[0074] Table 1: Placement of Kairomone device with respect to fan axis
S. No Angle w.r.t fan axis Height of evaporation or dissipation from air suction point Comments
1 15 45 mm Device with required dimension
2 45 30 mm Shape of device changes to accommodate height
3 60 20 mm Device can be made compact

[0075] The present invention also furthers the improvement of the evaporation apparatus with respect to the effective area of evaporation by two possibilities as described in Figure 6.
[0076] The Kairomone placement patterns are depicted in Figure 6. One, by increasing the number of Kairomone containers from one to ten or more. Preferably, the number of containers used is two (302) or four (304) (Figure 6A and 6B respectively) instead of a single container. Secondly, the increase in surface area can be achieved by increasing the number of exhaust vents/holes/provisions/pores (306) above the evaporation apparatus, keeping a single Kairomone container (308) (Figure 6C). The present invention thus aims for an effective evaporation apparatus by reducing the effect of the suction fan in the trap on the Kairomone vapour and by increasing the effective area of evaporation and ease of spread. The other aim of the present invention is to hold the evaporated kairomone for a bit enough time around the device and also spread it evenly in all directions.
[0077] Another aspect of the present invention discloses that surface area of evaporation is directly proportional to number of evaporation holes and Kairomone evaporators.
[0078] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, which has the capability to accommodate more than one Kairomone containers.
[0079] Figure 7 provides a view of Kairomone based mosquito attracting and killing device with kairomone (122) mounted at an angle of 45 degree and at height of 30 cm from suction point (102); the total device height being 150 cm; the device containing additional kairomone as a gel (120), for attracting mosquitoes.
[0080] In another embodiment, the present invention relates to a Kairomone based evaporation device for attracting and killing mosquitoes, which has multiple number of exhaust vents/holes.
[0081] In another preferred embodiment, the number of exhaust vents/holes can be 2 to 500.
[0082] In a preferred embodiment, the exhaust vents/holes could be present as pores or porous materials or any form of provisions above the dissipation or evaporation point.
[0083] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein dissipation of kairomone may occur via thermal evaporation, air blown, or nano material exposure to atmosphere.
[0084] In another preferred embodiment, Kairomone can be available as a liquid, gel, or coated on paper wherein the corresponding transfer method for dissipation can be chosen accordingly.
[0085] In another embodiment, the present invention relates to a Kairomone based device for attracting and killing mosquitoes, wherein other sources to attract mosquitoes may include secondary attraction by CO2 generated by photo catalytic reaction or source of UV light.
[0086] In another embodiment, the present invention relates to a Kairomone based evaporation device for attracting and killing mosquitoes, which can hold the evaporated or dissipated Kairomone for a bit enough time around the device and also spread equally in all directions.
[0087] The provision of multiple holes for evaporation leads to additional contribution to increase in surface area. In other words, this aspect of the present invention aims to hold the evaporated kairomone for a bit enough time around the device and also spread it evenly in all directions.
[0088] In yet another embodiment, the present invention provides a Kairomone based device for attracting and killing mosquitoes, which is useful for catching different species of mosquitoes based on time of the day and time of the month, by using different kairomones in the device.
[0089] Different species of mosquitoes require different attractant liquids or Kairomones. Based on mosquito surveillance inputs from server, the user can choose the required kairomone attractants to evaporate.
[0090] In another embodiment, the present invention relates to a kairomone based mosquito attracting and killing device, that can function using exhaust fan as suction source. As described in Figure 8, a kairomone pad (204) can be attached on the frame of exhaust fan (202); the mosquitoes will get attracted to the kairomone, will be sucked by the action of exhaust fan (202) and will ultimately be thrown out of the house. The pheromone pad (204) is replaced with a new one once it gets drained.
[0091] The diffused kairomone and secondary source, if present like CO2 attract the mosquitoes in the area from a distance, bringing it close to the device. On nearing the device the evaporated or diffused kairomone which is remaining above the device brings the mosquito as close as 10 to 15 feet of the device. Then light gets into the line of sight of mosquitoes and draws towards the suction point. The fan immediately pulls mosquito into the collecting tray and the mosquito is killed in a few seconds.
[0092] In another aspect, the present invention provides a Kairomone based device for attracting and killing mosquitoes, wherein the mosquito attracting and killing area can be physically separable or inseparable. In this concept, a unique detachable pheromone pad is used to attract the mosquitos. The detachable pheromone pad (204) can be placed on the top of the device by the means of adhesive tape (as depicted in Figure 11). This detachable pheromone pad attracts the mosquito by diffusing the pheromone. Once the pad gets drained, it can be replaced with a new pad by detaching the existing one. Figures 9 depicts a Kairomone based device for attracting and killing mosquitoes, Placed in a different shaped device to attract and kill, wherein the mosquito attracting and killing area can be physically separable. Herein, the kairomone is placed in the form of a detachable pad (204).
[0093] Figure 10 depicts Kairomone based device for attracting and killing mosquitoes, wherein the mosquito attracting and killing area can be physically separable. Herein the kairomone is placed in a different shaped device to attract and kill mosquitoes where detachable Kairomone diffuser in present in a paper form (702). In this concept, a detachable pheromone pad with a sticky paper (702) is used to attract the mosquitos. The detachable pheromone pad with sticky paper is attached to the top of the device. On exposing the pheromone to the surroundings by tearing down the sticky paper, the mosquitos are attracted towards the device. Once the pad gets drained it can be replaced with a newpad by detaching the existing one. Figure 11 depicts another Kairomone based device for attracting and killing mosquitoes, wherein the mosquito attracting and killing area can be physically separable. This device also has a detachable Kairomone diffuser (204).
