Description

TITLE OF THE INVENTION:

AIR PURIFIER FILTER

FIELD OF THE INVENTION

[0001] The present invention relates to an Air Purifier Filter, and particularly, to an air purifier filter that is adapted to be mounted on an object that is a source of or is in contact with a source of air pollutants, such that the air purifier filter reduces the air pollution while being energy efficient at the same time.

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] Today, air pollution is a big problem of the whole world. Air pollution levels are increasing not only in metro cities but almost everywhere all over the world. Cities bad hitten by such problem includes Beijing in China, New York, California, US, Delhi, Chennai, Mumbai, Kolkata in India etc.

[0004] In view of this problem, most of the countries of the world are also trying to find many solutions and remedies. But due to the high rate of population growth, the means of transport are also increasing rapidly in the same proportion and the measures taken are not able to solve the problem completely.

[0005] Few such measures taken by the authorities in India include compulsory pollution control check on vehicles running on road, introducing vehicles running on electric power (EV), and even limiting the number of vehicles by applying odd-even rule wherein vehicles are allowed to be run on alternate days based on their registration numbers. Howewver, the pollution is not controlled and the environment is under constant threat of being polluted badly.

[0006] In fact, if seen vehicles are not the only source of air pollution and there are many sources of air pollution like - smoke coming out of factories, smoke coming out of electric generators, dust blowing from road construction, smoke coming out of garbage etc. Said air pollution consists of a large portion of the dust from the road construction, the smoke emanating from the vehicles and the dust blowing from them. Also, pollution from the means of traffic that is being used by us, despite our unwillingness, continuously gets in the atmosphere and causes air pollution.

[0007] It can be seen that basically the desert coolers and vacuum cleaners also help in cleaning polluted air. However, it is impossible to apply Desert Cooler and Vacuum Cleaner everywhere to clear air pollution. Firstly, such devices are very large in size and secondly, they are not energy efficient as they consume a lot of power, i.e., electric power. Thirdly, it is difficult to make these devices portable because electric power also cannot be arranged at every place.

[0008] If said air purifier filters are installed in any vehicle, it would clean the contaminated air around the moving vehicle. This way the vehicle with the air purifier filters will easily clean the smoke discharged by another vehicles, factories, chimneys, etc. throughout the path it passes by. These vehicles themselves will help us clean all the air pollution such as bikes, cars, trucks, buses, road rollers and other means of transport which are available with us. However, the size of the filters being big, makes it difficult to arrange/ install the air purifier filters with the vehicle.

[0009] Therefore, there arises a need to provide an air purifier filter device capable of being installed in a vehicle and clean the air around itself.

OBJECTIVE OF THE INVENTION [0010] The present disclosure is aimed at providing an air purifier filter adapted to be installed in a vehicle.

[0011] Another objective of the present disclosure is to provide an air purifier filter adapted to be installed in a vehicle, is compact, economic, and cleans the air around the vehicle when in movement.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings.

[0042] The present disclosure provides an air purifier filter device (hereinafter “device (100)”) adapted to be installed in a vehicle for cleaning polluted air Al around the vehicle. In an embodiment, the vehicle may be a two-wheel, three-wheel, or four-wheel vehicle including but limited to a motorcycle, auto-rickshaw, car, bus, etc. The present disclosure is being made taking car as a vehicle. However, this is only an exemplary embodiment and as mentioned, the device 100 may also be installed with other vehicles. Also, in an embodiment, the polluted air Al may be a mixture of solid particles and gases in the air. Car emissions, chemicals from factories, dust, etc. may be suspended as particles.

[0043] Figure 1 illustrates a vehicle in normal running position, according to an embodiment of the present invention. Most vehicles generally follow each other and so the smoke from the front vehicle will be sucked and cleaned by the device 100 installed in the rear car. This process will continue for all vehicles. In the embodiment illustrated by Figure 1, Car A is following Car B. Car B may emit certain polluted air Al which may be directed towards the Car A. Therefore, the device 100 may be installed in the Car B in such a way that maximum polluted air Al is directed onto the device 100 in Car A. For example, the air should be directed in front of the Car A near the bumper and windshield in this filter. As soon as the smoke comes out of the vehicle in front, smoke should be absorbed through the filter installed in the bumper of the previous vehicle. Naturally, this process will be absorbed as soon as the pollution (smoke) is applied to every vehicle so that the smoke can get into the atmosphere at least.

[0044] Figure 2 illustrates an anti-air pressure in relation to a moving vehicle, in accordance with an embodiment of the disclosure. The vehicle may comprise an air duct boot 101 to allow the polluted air Al to enter the device 100 and an outlet vent 103 to allow the cleaned air A2 to leave the device 100. As the polluted air Al is directed at the device 100 installed in the vehicle, the air is sucked and cleaned using the pressure of the opposing air. The device 100 may be installed in the vehicle where the air pressure is the highest. When the vehicle moves, the polluted air Al will pass through the device 100 and the polluted air Al will be cleaned. When the vehicle is moving on the road, the air pressure is at the top and the bottom. As shown in figure 2, air is entered through air duct boot 101 and this strong air is delivered to the filter chamber 102 installed in the car. It is not required to do any work to create the "powerful air pressure" of this strong wind because this "powerful air pressure" is automatically received by the vehicle as it moves forward. The vehicle moves forward through the air and the air flows opposite to the vehicle which creates an opposing pressure in the area on the top and bottom of the car. The pressurized polluted air Al then enters through the air duct boot 101 placed at the front side of the vehicle and enters the device 100. Figure 5 and Figure 6 illustrate the structure of an air duct boot 101 in the air purifier filter device 100, according to an embodiment of the present invention. In an embodiment, air duct boot 101 may be made of plastic material. However, the air duct boot 101 may be fitted compactly under the bumper and windshield of the vehicle to prevent it from being destroyed as the air pressure of air is the highest at such areas due to the vehicle moving forward. The air duct boot 101 may be made according to the designs of the vehicles. In an exemplary embodiment, a vehicle may have to take air from the bumper and under the windshield. In another embodiment, the air duct boot 101 may be designed to be fitted in the middle as the vehicle needs air from the middle of the boot 101. The inlet of the boot 101 may be funnel shaped starting from a conical section 101c into which the polluted air Al is directed and moving into a cylindrical pipe 101b. The polluted air Al is then directed at a foam filter 104. [0045] As the polluted air A 1 moves form the cylindrical portion 101b toward the cylindrical portion 101b, due to the spread of this Air Duct Boot 101 from the front, more and more air from the front of the vehicle enters the Air Duct Boot 101 , and more polluted air A 1 is entered into the filter chamber 102.

[0046] Further, the air duct boot 101 may include a net or a mesh 101a at the base of the conical section 101c in an embodiment. Figure 7 illustrates a net-air duct boot 101 arrangement in the air purifier device 100, according to an embodiment of the present disclosure. The Air Duct Boot 101 may include a mesh 101a with small holes at the front. These mesh 101a particles prevent small stones etc. of diameter greater than that of the size of the holes of the mesh 101a from entering into the filter.

[0047] Figure 3 illustrates an air purifier filter device 100 filtering the air, according to an embodiment of the present invention. Polluted air Al is entered into the device 100 through the inlet of the air duct boot 101. The air duct boot 101 may comprise two layers of foam 104a, 104b (exemplary embodiment comprising two layers of foam). Figure 8 illustrates a foam filter 104a, 104b, according to an embodiment of the present disclosure. In an embodiment, the first layer of the foam 104a may comprise larger holes (chidri) and the second layer may comprise micro holes. As the first layer is pierced, large particle of dust and smoke stop at the filter layer. And because the second layer of foam 104b is micro perforated, micro particles are stopped by said second layer of foam 104b. This process may clean the polluted air Al. One of the reasons for applying two-layer filter of this foam 104a, 104b is that the filter of this foam layer 104a, 104b can be washed from time to time. And can be used again. For this reason, the cost of maintenance of this filter is also less.

[0048] Figure 4 illustrates a structure and functioning of the air purifier filter device 100 installed in a vehicle, according to an embodiment of the invention. The polluted air Al enters the air duct boot 101 (at 1) and leaves through the cylindrical section 101b. A flexible pipe 107 may be connected between the cylindrical section 101b of the air duct boot 101 (at 2) and the filter chamber 102. The flexible pipe 107 so directs the air (at 3) to the filter chamber 102 (at 4). Just behind the foam filter 104a, 104b, there may be blower fan 105 installed. A blower fan 105 may also be installed in the filter chamber 102 in an embodiment. The blower fan 105 may have more air drag capacity than any other fan. Further, car Battery 111 may be fitted. In an embodiment, the car Battery 111 may be a 12 Volt D.C. Power supply. The blower fan 105 may be turned on only when the vehicle is stuck in traffic. The blower fan 105 may be connected to an air sensor 108. When the air pressure from the front of the vehicle is low (the vehicle is stuck in traffic), then the blower fan 105 may turn on automatically and it is closed by the Blower Fan 105 Air sensor 108 when the air pressure increases. There may also be an ON - OFF Switch 109 (at 10). With this ON - OFF Switch 109, the fan can be turned ON or OFF. The blower fan 105 may be connected to a motor 106. Further, the filter chamber 102 may comprise outlet vent 103 (at 11) to release the clean air A2. This outlet vent 103 removes clean air A2 out of the device 100. This outlet vent 103 is on the back side of the vehicle.

[0049] In an embodiment, there may be a fuse 110 (at 13) which works as Protection Circuit, when the blower fan motor 106 is short, this fuse 110 will open so that the short circuit will be avoided.

[0050] An experiment is shown here to better explain the disclosure. However, said experiment does not pose any limitation to the scope of the invention and only poses an exemplary embodiment.

[0051] To measure the air pressure of the air, a weighing machine scale which measures up to 50 Kg is made. It will be used to measure air pressure. A cardboard whose length is 17.5 inches and width is 12 inches is grinded. Area of the cardboard is 210 square inches. The cardboard piece is applied on the weighing machine scale in such a way that air pressure of air can be measured in grams when the air on the cardboard piece falls from the front. The cardboard digital weighing machine scale (salter scale) may be placed in front of a table fan. Then 190 grams of air pressure may be found on the digital weighing machine scale as a result. The area of the cardboard may be 210 square inches. While the Table Fan may consume 75 Watts of Electric Power.

[0052] Further, the above cardboard fitted digital weighing machine scale(salter scale) is placed in front of a Cooler Fan. Then Air Pressure of 330 grams of air may be found on the digital weighing machine scale. While the Cooler Fan may consuming 125 Watt Electric Power.

[0053] Furthermore, the same cardboard fitted digital weighing machine scale is applied al weighing machine scale on a bike in front of 30 Km / h Speed. Then on a digital weighing machine scale, air pressure of 610 grams of air may be found on the cardboard.

[0054] Also, when the same cardboard fitted digital weighing machine scale is fitted on the same bike in front of 60 Km / h speed. Then on the digital weighing machine scale, Air Pressure of 2310 grams of air may be found on the cardboard. The results are as follows:

To get 190 gram Air Pressure, Electric consumed = 75 Watt

To get 1 gram Air Pressure, Electric power required = 75 190 Watt

To get 2300 grams of Air Pressure, Electric power required = 75 190 x 2300

= 907.8 Watt

[0055] Through the above experiments, it was concluded that as the velocity of the vehicle increases or the air surface increases, the air pressure will also increase. That is, the higher the size of the air duct boot 101, and the higher the velocity of the vehicle, the more the air will pass through the filter and our objective of cleaning the air pollution will be fulfilled.

[0056] This experiment also concludes how much electric power will be required to create a pressure equal to the opposing air from the front of the vehicle. The opposing air from the front of the vehicle was still useless. But through this T4PFW Air Purifier Filter, we can do a very good use of this opposing air to clean the air pollution.

[0057] Another experiment is as below: E/- A 5 KVA Diesel Engine Alternator is running on full load. In front of the silencer of that Diesel Engine Alternator, when the air duct of the device 100 is booted, it may be found that as soon as a Blower Fan 105 was on, all the Black Smoke is vacuumed by the device 100 and clean air A2 came out from the exit vent side.

[0058] By the above experiment, it is concluded that as soon as the smoke comes out from the Vehicles, the pollutant should be absorbed through the Air Duct Boot 101. So air pollution can be reduced to a great extent. The objective of clearing air pollution is fulfilled. [0059] The figures and the forgoing description give examples of embodiments. Those skilled in the art will appreciate that one or more of the described elements may well be combined into a single functional element. Alternatively, certain elements may be split into multiple functional elements. Elements from one embodiment may be added to another embodiment. For example, orders of processes described herein may be changed and are not limited to the manner described herein. Moreover, the actions of any flow diagram need not be implemented in the order shown; nor do all of the acts necessarily need to be performed. Also, those acts that are not dependent on other acts may be performed in parallel with the other acts. The scope of the embodiments is by no means limited by these specific examples. Numerous variations, whether explicitly given in the specification or not, such as differences in structure, dimension, and use of material, are possible.
