DESC:FIELD
The present disclosure relates to the field of mechanical engineering. Particularly, the present disclosure relates to the field of air ventilating systems.
BACKGROUND
Generally, while travelling in enclosed vehicles, heat is generated within the vehicles. An enclosed vehicle usually has an enclosed interior space isolated from the surroundings to avert air from the atmosphere to enter inside the vehicle. Such enclosed space with no provision for ventilation may cause suffocation and discomfort to the occupants/passengers of the vehicle. Heat is also generated inside vehicles due to the operation of the components of the vehicles disposed within, and due to temperature variations in the air. Further, either stale air or moist air trapped inside the vehicle leads to suffocation of the occupants/passengers seated in the vehicles.
Therefore, there is a need for an air ventilating system that facilitates ventilation of fresh air in vehicles and thereby reduces suffocation caused to the passengers seated in the vehicles. Further, there is a need for an air ventilating system that exhausts air contained within the enclosed interior space of vehicles to the atmosphere.
OBJECTS
Some of the objects of the present disclosure, which at least one embodiment herein satisfies, are as follows.
It is an object of the present disclosure to ameliorate one or more problems of the prior art or to at least provide a useful alternative.
An object of the present disclosure is to provide an air ventilating system for a vehicle.
Another object of the present disclosure is to provide an air ventilating system that acts as a blower for supplying fresh air in the vehicle.
Yet another object of the present disclosure is to provide an air ventilating system that acts as an exhaust for removing and directing air contained within the vehicle into the atmosphere.

The foregoing description of the specific embodiments will so fully reveal the general nature of the embodiments herein that others can, by applying current knowledge, readily modify and/or adapt for various applications such specific embodiments without departing from the generic concept, and, therefore, such adaptations and modifications should and are intended to be comprehended within the meaning and range of equivalents of the disclosed embodiments. It is to be understood that the phraseology or terminology employed herein is for the purpose of description and not of limitation. Therefore, while the embodiments herein have been described in terms of preferred embodiments, those skilled in the art will recognize that the embodiments herein can be practiced with modification within the spirit and scope of the embodiments as described herein.
Figure 1 to Figure 4B together illustrate an air ventilating system 100 in accordance with an embodiment of the present disclosure. The air ventilating system 100 includes a venturi 10, a first conduit 14, a second conduit 12 and a plug 16.
In one embodiment, the venturi 10 is fitted on a vehicle. In another embodiment the air ventilating system 100 includes fitment for fitting the venturi 10 to a vehicle. The venturi 10 has a first converging portion 10a and a second converging portion 10b connected to each other at converged ends thereof thereby forming the venturi 10. The first converging portion 10a and the second converging portion 10b may either be integral or may be connected to each other. The venturi 10 has an operative front end 11a and an operative rear end 11b. Air enters the venturi 10 from the operative front end 11a and exits/exhausts from the venturi through the operative rear end 11b.
The first conduit 14 extends from the venturi 10 such that it facilitates entry of atmospheric air inside an enclosed space of the vehicle from the operative front end 11a of the venturi 10. The second conduit 12 extends from the venturi 10 such that it facilitates exhaust of air contained in the enclosed space of the vehicle to the atmosphere via the operative rear end 11b of the venturi 10. The plug 16 selectively enables and disables the air entry in the vehicle and exhaustion of air from the vehicle. The plug 16 acts as a valve having a through bore and is configured to be deployed between a first operative position and a second operative position. Figure 1 of the accompanying drawing illustrates the air ventilating system 100 where the plug 16 is in the second operative position and Figure 2 illustrates the air ventilating system 100 where the plug 16 is in the first operative position. In the first operative position, the plug 16 extends into the venturi 10 to facilitate transmission of atmospheric air from the operative front end 11a through the bore of the plug 16 into the enclosed space of the vehicle via the first conduit 14. In the second operative position, the plug 16 seals the first conduit 14 to facilitate exhaustion of air from the enclosed space of the vehicle to the atmosphere via the second conduit 12 and the operative rear end of the venturi 10.
In one embodiment, the plug 16 is a sliding element fitted in such a way that it is configured to toggle between an exhaust mode and a blower mode. In the exhaust mode, as illustrated in Figure 3A, the plug 16 seals the first conduit 14 to restrict fluid communication/flow of air between the first conduit 14 and the operative front end 11a of the venturi 10. When a vehicle is in motion and the air is flowing with high pressure from the operative front end 11a to the operative rear end 11b, low pressure is generated at the inlet of the second conduit 12. This pressure difference facilitates exhaustion of air contained within the vehicle/enclosed space through the second conduit 12 and the operative rear end 11b of the venturi 10 into the atmosphere. The flow path Pe1 of the air in exhaust mode is illustrated in Figure 3A.
In the blower mode, as illustrated in Figure 3B, the plug 16 is toggled/ pulled out from the first conduit 14 and extended in the venturi 10 such that the atmospheric air received from the operative front end 11a is directed into the vehicle/enclosed space through the first conduit 14 thereby blowing atmospheric air into the vehicle/enclosed space. The flow path Pb1 of the atmospheric air is illustrated in Figure 3B.
In one embodiment, the air ventilating system 100 includes a filter 18 which is fitted to the first conduit 14 to prevent foreign particles from the atmosphere to enter the vehicle along with air when the air ventilating system 100 is in the blower mode.
In another embodiment, the plug 16 can be deployed between the first operative position and the second operative position by manually controlling the plug with the help of a toggle key, or by using either of a hydraulic system, a pneumatic system and an electrical system. Further, in an embodiment, the air ventilating system 100 includes a sensor configured to sense oxygen and/or carbon dioxide present within the enclosed space of the vehicle to facilitate manual or automatic deployment of the plug 16 between the first operative position and the second operative position.
In accordance with one embodiment of the present disclosure, the air ventilating system 100 is fitted on the vehicle 25 (illustrated in Figures 4A and 4B). More specifically, the venturi 10 is fitted on the roof 25a of the vehicle 25 and the first conduit 14 and the second conduit 12 are in fluid communication with the enclosed space S of the vehicle 25. When the vehicle 25 is in motion and the air ventilating system 100 is in the exhaust mode, the movement of the vehicle 25 causes the atmospheric air to flow from the operative front end 11a to the operative rear end 11b thereby generating a low pressure at the operative rear end 11b, which enables the air contained in the enclosed space S to flow towards the atmosphere through the second conduit 12 and the operative rear end 11b. This allows stale air that may cause suffocation to exit the vehicle. Pe2 denotes the direction of flow of air in the exhaust mode. In case of the blower mode, the plug 16 provides a path for the atmospheric air to flow from the operative front end 11a via the first conduit 14 into the enclosed space S thereby allowing fresh air to enter the vehicle 25. Pb2 denotes the direction of flow of fresh air into the vehicle 25 in case of the blower mode.
