[0023] Figure 1 further illustrates a motorized sliding unit 112 integrated in between the structure 108 and roller 109, a thermocouple 113 integrated inside the structure 108, a L-shaped bar 114 arranged on the structure 108 and integrated with an electric igniter 115, an ultrasonic emitter 116 arranged on the body 101, an air blower 117 installed on the bar 114, and a second motorized clipper 118 integrated with the bar 114, and a motorized cutting unit 119 integrated with the bar 114.

[0024] The proposed device comprises of a body 101 made up of any material, designed for efficient repelling of insect. The body 101 is encased with various components associated with the device arrange in sequential manner that aids in repelling the insects. Upon placing of the body 101 over placed over a fixed surface around an area, the user requires to activate the device manually by pressing a switch button associated with the device and integrated with the body 101. The button is a type of a switch that is internally connected with the device via multiple circuits that upon pressing by the user, the circuits get closed and starts conducting electricity that tends to activate the device and vice versa. After activation of the device by the user, a microcontroller associated with the device generates a commands to operate the device accordingly.

[0025] After activation of the device, the microcontroller actuates an artificial intelligence-based imaging unit 102 synced with an acoustic sensor installed on the body 101 for detecting presence of insects/mosquitoes in the area. The imaging unit 102, mentioned herein comprises of comprises of a camera and processor that works in collaboration to capture and process the images of surrounding of the body 101. The camera firstly captures multiple images of the surrounding, wherein the camera comprises of a body, electronic shutter, lens, lens aperture, image sensor, and imaging processor that works in sequential manner to capture images of the surrounding. After capturing of the images by the camera, the shutter is automatically open due to which the reflected beam of light coming from the surrounding due to light is directed towards the lens aperture. After that the reflected light beam passes through the image sensor.

[0026] The image sensor now analyzes the beam to retrieve signal from the beams which is further calibrate by the sensor to capture images of the surrounding in electronic signal. Upon capturing images, the imaging processor processes the electronic signal into digital image. When the image capturing is done, the processor associated with the imaging unit 102 processes the captured images by using a protocol of artificial intelligence to retrieve data from the captured image in the form of digital signal. The detected data in the form of digital signal is now transmitted to the linked microcontroller based on which the microcontroller acquires the data to detect the area.

[0027] Based on detection of the area, the acoustic sensor detects presence of insects/mosquitoes in the area. The acoustic sensor operates by capturing ambient sound waves of the insects and analyzing the frequency and pattern of the noise to differentiate between various sounds. When the sensor detects a sound that matches the characteristic equivalent to frequency of mosquitoes or other insects, the sensor calibrates frequency to detect the presence of mosquitoes or insects. Based on detecting the presence of insects/mosquitoes in the area, a laser detection sensor integrated on the body 101 and synced with the imaging unit 102 for detecting kind of the detected mosquitoes.

[0028] The laser detection sensor mentioned herein works by emitting a focused laser beam that interacts with the insect's wings or body and passes through the detection zone. The interaction generates optical signals, such as light scattering or changes in the laser's intensity and frequency, which are analyzed to capture specific patterns or characteristics unique to the insect species are processed in real-time and synced with the imaging unit 102 to identify and classify the detected mosquito. This precise detection method allows for accurate species identification of kind of the detected mosquitoes.

[0029] Based on detection of the presence of insects/mosquitoes in the area and kind of the detected mosquitoes, the microcontroller evaluates a set of ingredients repelling the determined kind of mosquito/insect. Herein, the ingredients preferably include materials for cosmetic preparation such as tea tree oil, rose marry oil, carrot seed oil, beeswax, zinc oxide, propylene glycol, distilled water, phosphate buffer, tri chloro acetic acid, ferric chloride, ascorbic acid, oxalic acid, potassium ferri cyanide that are highly provide beneficial properties in skin care and cosmetic formulations by offering a range of effects, such as antibacterial (tea tree oil), anti-inflammatory (rosemary oil), moisturizing (carrot seed oil), and protective (zinc oxide).

[0030] Based on evaluation of the ingredients to be utilized for repelling the determined kind of mosquito/insect, the microcontroller directs multiple electronically controlled nozzles 104 integrated with a multi-sectioned chamber 103 arranged on top portion of the body 101 to dispense an optimum amount of different ingredients stored in the chamber 103 onto a container 105 arranged underneath the chamber 103. The nozzle 104 includes solenoids, piezoelectric actuators, or motor-driven mechanisms that converts electrical signals into mechanical motion. The nozzle 104 is controlled by a control unit that sends electrical signals to the actuation mechanism.

[0031] The control unit includes a pulse width modulation (PWM) or analog voltage control. The primary function of the nozzle 104 is to control the opening and closing of the nozzle’s orifice or aperture. Upon receiving the appropriate electrical signal by the actuation mechanism, it initiates the motion that opens or closes the nozzle 104. This action controls the flow of the ingredients through the nozzle 104. The nozzle 104 allows precise control over the flow rate and direction of the ingredients. By modulating the actuation mechanism according to the desired parameters, the nozzle 104 is capable to regulate the flow and provide accurate dispensing of the ingredients from the chamber 103 on the container 105.

[0032] Simultaneously, the microcontroller actuates a motorized stirrer 106 assembled at base of the container 105 to rotate for mixing the ingredients to formulate the cosmetics. The stirrer 106 comprises of a blade coupled with a motor that is activated by the microcontroller to rotate the blade with specified speed in order to mix the ingredients. After that the microcontroller actuates a pair of Peltier units 107 integrated in the container 105 to heat the ingredients for melting herbal wax accommodated in the container 105 as one of the ingredients. Peltier unit 107 comprises of junctions and a thermoelectric generator (TEG) that is a solid unit which converts the heat into electric energy by the phenomena of see beck effect that is also known as form of thermoelectric effect. Further when the current flows through the junctions, the heat is removed from one junction to regulate the temperature within the container 105 to heat the ingredients for melting wax accommodated in the container 105 as one of the ingredients.

[0033] During formulation of the one of the ingredients, the microcontroller actuates a motorized roller 109 integrated in a cylindrical structure 108 arranged on the body 101 to rotate for uncoiling a wick 110 coiled on the roller 109. The roller 109 is coupled with a motor that is activated by the microcontroller to rotate the roller 109 with specified speed to uncoil the wick 110 from the roller 109 that is gripped by a first motorized clipper 111 integrated at base of the structure 108. The clipper 111 is linked with a hinge that is activated by the microcontroller to provide back and forth movement to clipper 111 for gripping the uncoiled wick 110. Simultaneously, the microcontroller actuates a motorized sliding unit 112 integrated in between the structure 108 and roller 109 to translate the roller 109 towards an opening crafted on top portion of the structure 108 for positioning a length of wick 110 along the structure 108.

[0034] The sliding unit 112 mentioned herein comprises of a rail unit that provides a guided path for linear movement. The rail unit usually includes a pair of parallel rails or tracks, along which the sliding unit 112 moves. The slider carriage, also called a stage or platform equipped with a mechanism to minimize friction and ensure smooth motion. The sliding unit 112 incorporates a motor and a drive mechanism to generate linear motion. The motor is connected to a drive mechanism, such as a belt, lead screw, or ball screw. The drive mechanism converts the rotational motion of the motor into linear motion, propelling the slider carriage along the rail unit to translate the roller 109 for positioning a length of wick 110 along the structure 108.

[0035] Simultaneously, the microcontroller actuates a pump configured with a conduit arranged in between the container 105 and the opening to pump the molten herbal wax inside the structure 108. The pump operates by utilizing a motor-driven mechanism, such as a diaphragm, gear, or peristaltic system, to create pressure that drives the molten herbal wax through the conduit. The mechanism ensures a steady and controlled flow of the wax from the container 105 to the desired opening within the structure 108. After the passing of the molten wax in the structure 108, by the microcontroller actuates a thermocouple 113 integrated inside the structure 108 to cool the molten wax for obtaining an herbal candle.

[0036] The thermocouple 113 mentioned herein operates by measuring temperature of the molten wax as it cools within the structure 108. The thermocouple 113 consists of two dissimilar metal wires joined at one end, which generate a voltage proportional to the temperature difference between the junction (hot end) and the reference (cold end). The microcontroller reads this voltage to detect the wax's temperature in real-time. Based on the wax's temperature, the thermocouple 113 controls cooling mechanisms to ensure the wax solidifies uniformly into the herbal candle.

[0037] Upon formation of the herbal candle as detected by the microcontroller via the imaging unit 102, the microcontroller actuates a second motorized clipper 118 integrated with a L-shaped bar 114 arranged on the structure 108 for gripping the wick 110 of the herbal candle. Simultaneously, the microcontroller actuates a motorized cutting unit 119 integrated with a robotic link for cutting the wick 110 by left some portion for igniting. The robotic link is similar to a robotic arm that comprises of a shoulder, elbow and wrist. All these parts are configured with the microcontroller. The elbow is at the middle section of the arm that allows the upper part of the arm to move the lower section independently. Lastly, the wrist is at the tip of the upper arm and attached to the end effector works as hand for moving the cutting unit 119 in contact with the wick 110 along with rotating the cutting unit 119 with specified via actuation of a motor coupled with the cutting unit 119 for cutting the wick 110. Simultaneously, the microcontroller actuates an electric igniter 115 integrated with the bar 114 to lit the wick 110 integrated on the candle for flaming the candle.

[0038] The electric igniter 115 mentioned herein comprises of a thermocouple, gas burner, valve and sensor that works in collaboration to ignite fire. On the activation of the igniter 115, the gas starts releasing from the chamber 103 which gets ignite and heats up the thermocouple. After that the sensor converts that heat into electronic signal in order to transmit to the microcontroller. Now the microcontroller analyses the signal to detect the ignition. On the detection, the microcontroller commands to open gas valve to the burner and igniter 115 ignites the gas coming from the burner which is further ignite out as a fire pit over the wick 110 of the candle to burn the wick 110 of the candle to produce fumes that repels the determined kind of mosquitoes/insects.

[0039] Additionally, an ultrasonic emitter 116 is assembled on the body 101 to emit ultrasonic vibrations for deterring insects from proximity of the body 101. The ultrasonic emitter 116 works by generating high-frequency sound waves, typically above the range of human hearing (20 kHz and higher), which are emitted into the surrounding environment to interfere with the sensory and communication unit of insects, particularly by disrupting the navigation, mating, and feeding behaviors. The ultrasonic vibrations confuse or repel the insects, causing them to avoid the area around the body 101.

[0040] Moreover, the use also accesses a display panel integrated with the body 101 for blowing off the candle based on that the microcontroller actuates an air blower 117 installed on the bar 114 to blow air onto the candle to blown off. The display panel works by using LCD (liquid crystal Display) that are manipulated by electric currents to control the passage of light through the display panel. When an electric current is applied, the liquid crystals align in a way that either allows light to pass through or blocks the light, creating the images and colors that is being visible in the LCD of the display panel regarding the candle to blown off that is further change the electric charge at the location of the touch to register as input. The user input is then sent to the liked microcontroller to process the input.

[0041] Upon processing of the input given by the user, the microcontroller generates commands to actuate the blower 117 for blowing air on the candle. The blower 117 operates by sing a small motorized fan or air pump that generates a stream of air when activated. When the user accesses the display panel to blow out the candle, the microcontroller sends a signal to activate the blower 117. The motor drives the fan, which pushes air through a nozzle or duct aimed at the candle's flame. The force of the air disrupts the flame, causing it to extinguish. The airflow is controlled by the microcontroller to ensure the right amount of air is directed at the candle to blown off.

[0042] For moving the body 101 to another location, the user access the body 101 to move the body 101 via a pair of track wheel 120 integrated with the body 101. The track wheel 120 works by a pair of continuous tracks, similar to bulldozers, which are driven by user to move the body 101 across surfaces. Each track wheel 120 is made of a flexible material with a series of interlocking links that grip the ground, providing stability and traction.

[0043] A battery (not shown in figure) is associated with the device to offer power to all electrical and electronic components necessary for their correct operation. The battery is linked to the microcontroller and provides (DC) Direct Current to the microcontroller. And then, based on the order of operations, the microcontroller sends that current to those specific electrical or electronic components so the user effectively carry out their appropriate functions.
