Description

Technical Field

[0001] The utility model relates to the technical field of air conditioning filter elements, in particular to a multi-layer composite filtering mechanism for air conditioning filter elements. Background Art

[0002] The air conditioning filter is a filter installed in the car's air conditioning position. It can absorb dust particles, relieve respiratory pain, reduce irritation to allergy sufferers, and protect the air conditioning cooling system. The main function of the air conditioning filter is to filter out dust, pollen and other impurities in the air to ensure the cleanliness and hygiene of the air in the car. At the same time, it can also filter out some harmful bacteria and viruses to improve the quality of the air in the car.

[0003] An air conditioning filter is generally composed of a filtering mechanism that is repeatedly bent and folded on the outside and inside, wherein the filtering mechanism consists of a multi-layer filtering structure such as a non-woven fabric layer for dust filtering and an activated carbon layer for filtering harmful substances. During the use of existing air conditioning filters, since the outside air contains more dust and the amount of harmful substances is often small, a large amount of dust often adheres to the filtering mechanism when filtering gases. As a result, when the filtering strength of the activated carbon for harmful substances is not reduced, the non-woven fabric is affected by the attachment of a large amount of dust, which affects the passage of gas through the air conditioning filter. In addition, since a large amount of dust adheres to the air conditioning filter, the gas that subsequently passes through the air conditioning filter will have a thrust on the dust, which may cause the dust to be directly pushed into the external holes of the air conditioning filter, affecting the use of the air conditioning filter.

DETAILED DESCRIPTION

[0021] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0022] The utility model provides a technical solution: Figure 1 The utility model discloses a multi-layer composite filter mechanism for an air conditioning filter element, comprising a rectangular box 1 and a filter element body 2. The filter element body 2 is a multi-layer composite filter mechanism composed of multiple filter layers such as a graphene layer and a non-woven fabric layer. A partition plate 3 is fixedly installed in the rectangular box 1. The filter element body 2 is inserted into the bottom opening of the rectangular box 1, and the outer peripheral wall of the filter element body 2 is in contact with the inner wall of the rectangular shell. The filter element body 2 is located below the partition plate 3, and an air guide mechanism 4 is provided on the top side of the partition plate 3.

[0023] In this embodiment, the partition 3 can divide the internal space of the rectangular box 1 into two spaces, which are used for storing water and the filter element body 2 respectively;

[0024] It should be noted that the filter element body is a multi-layer composite filter structure composed of a multi-layer filter structure including a non-woven filter layer and a honeycomb activated carbon filter layer.

[0025] In a further preferred embodiment of the present invention, Figure 1-3 As shown, a water absorbing plate 5 is provided above the partition 3, and the outer peripheral wall of the water absorbing plate 5 is fixedly connected to the inner wall of the rectangular box 1, and the water absorbing plate 5 is a sponge board;

[0026] In this embodiment, when the device is in use, if the rectangular box shakes, the water in the rectangular box will not splash into the top opening of the circular tube due to the blocking of the water absorption plate.

[0027] In a further preferred embodiment of the present invention, Figure 2 and Figure 3As shown, the air guide mechanism 4 includes a plurality of one-way valves 41, which are fixedly arranged on the water absorption plate 5, and the spacing between two adjacent one-way valves 41 is equal, the exhaust end of the one-way valve 41 is matched with the clearance of the top side of the partition 3, and the air inlet end of the one-way valve 41 extends to the top side of the rectangular box 1 and is fixedly connected to the box wall of the rectangular box 1;

[0028] In this embodiment, according to the above, the setting of the one-way valve 41 allows the gas passing through the filter element body 2 to be injected into the water first, and the water in the rectangular box 1 will not flow out of the rectangular box 1 through the one-way valve 41.

[0029] In a further preferred embodiment of the present invention, Figure 3 As shown, a plurality of circular tubes 42 are provided in the partition plate 3 and the water absorption plate 5. The bottom end of the circular tube 42 is coplanar with the bottom side of the partition plate 3, the top end of the circular tube 42 is in clearance with the inner wall of the rectangular box 1, and the circular tube 42 is located in the middle position between the corresponding two one-way valves 41;

[0030] In this embodiment, the gas flowing out from the one-way valve 41 emerges from the water and is guided to the top side of the filter element body 2 by the circular tube 42. Since the top opening of the circular tube 42 is much higher than the water surface, it takes a certain amount of time for the gas emerging from the water to flow into the top opening of the circular tube 42. During this period of time, the water in the gas is automatically separated from the gas due to its own gravity and falls to the upper side of the water absorption plate 5.

[0031] In a further preferred embodiment of the present invention, Figure 2 and Figure 4 As shown, a limiting ring 43 is fixedly installed in the circular tube 42, a sealing plate 44 is provided on the bottom side of the limiting ring 43, and the outer peripheral wall of the sealing plate 44 is gap-matched with the inner wall of the corresponding circular tube 42, a push rod 45 is passed through the center position of the limiting ring 43, and the bottom end of the push rod 45 is fixedly connected to the sealing plate 44, and the top end of the push rod 45 extends to the outside of the rectangular box 1 and is slidably connected to the box wall of the rectangular box 1;

[0032] In the present embodiment, during the upward movement of the sealing plate 44, the sealing plate 44 will not slide out of the circular tube 42 due to the mutual interference between the top side of the sealing plate 44 and the limiting ring 43. In addition, during the mutual interference between the sealing plate 44 and the limiting ring 43, the sealing mechanism formed by the sealing plate 44 and the limiting ring 43 will block the top opening of the circular tube 42, thereby preventing a large amount of external dust from entering the space between the partition 3 and the inner wall of the rectangular box 1 through the feed port of the rectangular box 1 and the circular tube 42.

[0033] In a further preferred embodiment of the present invention, Figure 4As shown, a restraining ring 46 is provided on the outer peripheral side of the push rod 45, and a plurality of support rods 47 are provided on the outer peripheral side of the restraining ring 46, and the two ends of each support rod 47 are respectively fixedly connected to the outer peripheral wall of the corresponding restraining ring 46 and the inner wall of the top opening of the corresponding circular tube 42;

[0034] In this embodiment, during the movement of the above-mentioned sealing plate 44, due to the mutual interference between the push rod 45 and the constraint ring 46, the push plate can only be located at the center axis position of the circular tube 42 and move in a linear trajectory, so that there will be no positional deviation during the movement of the sealing plate 44, and the interference between the sealing plate 44 and the limit ring 43 can always seal the opening of the circular tube 42.

[0035] In a further preferred embodiment of the present invention, Figure 4 As shown, a spring 48 is provided between the restraining ring 46 and the sealing plate 44, and both ends of the spring 48 are fixedly connected to the corresponding restraining ring 46 and the corresponding sealing plate 44 respectively;

[0036] In this embodiment, during the separation of the sealing plate 44 and the limiting ring 43, the distance between the sealing plate 44 and the restraining ring 46 increases, thereby stretching the spring 48. After the sealing plate 44 loses the external force constraint, the sealing plate 44 is automatically pulled toward the limiting ring 43 and fits tightly with the limiting ring 43 due to the contraction deformation of the spring 48.

[0037] In a further preferred embodiment of the present invention, Figure 1 and Figure 2 As shown, a threaded hole 6 is provided on the outer wall of the rectangular box 1, and the threaded hole 6 is located above the partition 3, and a plug 7 is installed in the threaded hole 6, and the two ends of the plug 7 are coplanar with the inner and outer walls of the rectangular box 1, respectively. The plug 7 is cylindrical, and the outer ring edge of one end of the plug 7 is an arc surface, and the other end of the plug 7 is provided with a hexagonal groove;

[0038] In this embodiment, after the plug 7 in the threaded hole 6 is unscrewed, the sewage in the rectangular box 1 can be poured out of the rectangular box 1, and the water in the rectangular box 1 can be replaced to prevent excessive dust in the water in the rectangular box 1 from causing the water's adsorption capacity for dust to decrease and affect the use of the device.

[0039] Working principle: When installing the improved air conditioning filter element group, first put the device on its side and use a hexagonal wrench to screw the plug 7 out of the threaded hole 6. If there is water in the rectangular box 1 at this time, the sewage in the rectangular box 1 can be poured out from the threaded hole 6 by tilting the rectangular box 1, and then water is injected into the rectangular box 1 from the threaded hole 6, so that the rectangular box 1 is stored with water that fills the space between the water absorption plate 5 and the partition 3, and then the plug 7 is screwed back into the threaded hole 6 to block the threaded hole 6, and finally the rectangular box 1 is slowly rotated to lay the rectangular box 1 flat. During the tilting process of the rectangular box 1, the water on the sealing plate 44 flows out from the top opening of the circular tube 42. According to the above, the addition or replacement of water in the rectangular box 1 can be completed. After the addition or replacement of water in the rectangular box 1 is completed, the rectangular box 1 is laid flat, and then the push rods 45 are pressed in sequence so that the water remaining on the top side of the sealing plate 44 can slide off the sealing plate, and finally flow to the outside from the bottom opening of the rectangular box 1;

[0040] Then place the filter element body 2 on the external plane, and then put the bottom opening of the rectangular box on the filter element body 2 so that the filter element body is inserted into the bottom opening of the rectangular box 1. Due to the friction between the filter element body 2 and the inner wall of the bottom opening of the rectangular box 1, the filter element body 2 is constrained and limited to the bottom opening of the rectangular shell. According to the above operation, the installation and replacement of the filter element body 2 can be completed;

[0041] It should be noted that when disassembling the filter element body 2, the filter element can be directly pulled out from the opening of the rectangular box 1;

[0042] After the water in the rectangular box 1 and the filter element body 2 are installed, the device is directly placed in the air conditioner filter element installation cavity, and the cover is installed to complete the installation of the rectangular box 1. During the installation of the cover, due to the mutual interference between the cover and the push rod 45, the sealing plate 44 can be pushed away from the limit ring 43, so that the closed state between the push plate and the top opening of the separation tube 42 is released;

[0043] It should be noted that when the cover is removed, the restraining force on the push rod 45 disappears, and due to the reset deformation of the spring 48, the piston plate is pulled upward to contact with the limit ring 43 to close the top opening of the round tube 42;

[0044] During the use of the air conditioning filter element, the outside air flows into the rectangular box 1 through the one-way valve 41, and is introduced into the water in the rectangular box 1 through the one-way valve 41. Due to the adsorption of dust in the air by water, the dust in the air can be trapped and stored in the water. The cleaned gas travels in the water, then passes through the holes of the water absorption plate 5 and moves to the top of the water absorption plate 5, and finally passes through the top opening of the circular tube 42, the gap between the limit ring 43 and the sealing plate 44 and the inner wall of the circular tube 42, and is introduced from the circular tube 42 to the bottom of the sealing plate 44, and finally the dust is filtered by the filter element body 2;

[0045] It should be noted that, in the process of gas passing through the holes on the water-absorbing plate 5, the water in the holes of the water-absorbing plate 5 will be pushed out, and due to the effect of the water's own gravity, the water will automatically separate from the gas and fall to the top side of the water-absorbing plate 5, and then flow back into the water in the rectangular box 1 through the holes of the water-absorbing plate 5. When the water passes through the holes of the water-absorbing plate 5 from the top side of the water-absorbing plate 5, the dust attached to the holes on the bottom side of the water-absorbing plate 5 can be pushed into the water to clean the water-absorbing plate 5.

[0046] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected.
