DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0032] In this embodiment, the first filter screen 10, the second filter screen 11, the third filter screen 12 and the fourth filter screen 13 are used to filter the incoming air to improve the cleanliness of the incoming gas. Figure 1-Figure 2 As shown:

[0033] A first docking plate 4 is installed on the top outer wall of the outer shell 1, and a top plate 5 is arranged above the outer shell 1, and second docking plates 6 are welded and fixed on both the left and right sides of the top plate 5, and bolt holes 7 are opened on the second docking plate 6 and the first docking plate 4, and a sealing strip 8 is installed on the lower surface of the top plate 5;

[0034] The inner side of the outer shell 1 is provided with a first filter 10, a second filter 11, a third filter 12 and a fourth filter 13 for filtering air, and a support block 18 is provided between the first filter 10 and the second filter 11, the second filter 11 and the third filter 12, and the third filter 12 and the fourth filter 13, and the support block 18 is inclined and made of rubber;

[0035] When using the self-closing antibacterial air filter, first install the outer shell 1 in the corresponding position, and arrange the first filter 10, the second filter 11, the third filter 12 and the fourth filter 13 on the inner side of the outer shell 1, and the first filter 10, the second filter 11, the third filter 12 and the fourth filter 13 are distributed in sequence from the air inlet 2 to the air outlet 3, so the first filter 10, the second filter 11, the third filter 12 and the fourth filter 13 can be used to filter the incoming air to improve the cleanliness of the incoming gas, and a support block 18 made of rubber material is installed between the first filter 10 and the second filter 11, the second filter 11 and the third filter 12, and the third filter 12 and the fourth filter 13, and the support block 18 and the first filter 10, the second filter 11, the third filter 12 and the fourth filter 13 are all in close contact with each other, so the support block 18 can play a supporting role to ensure the normal operation of the air filtration work. Example

[0036] In this embodiment, the coarse filter layer 1004, the fine filter layer 1003 and the antibacterial layer 1002 are filtered in sequence, effectively intercepting dust in the air and also having a sterilizing effect on the air. Figure 4-Figure 6 As shown:

[0037] A first guide plate 16 is provided between the first filter screen 10 and the air inlet 2, and a second guide plate 17 is provided between the air outlet 3 and the fourth filter screen 13;

[0038] The first filter 10, the second filter 11, the third filter 12 and the fourth filter 13 are arranged sequentially from right to left, and the second filter 11 is a deodorizing filter, and the third filter 12 is a formaldehyde removal filter, and the fourth filter 13 is a HEPA filter. The first filter 10 includes a fixed frame 1001, an antibacterial layer 1002, a fine filter layer 1003 and a coarse filter layer 1004, and the antibacterial layer 1002, the fine filter layer 1003 and the coarse filter layer 1004 are arranged sequentially from left to right;

[0039] Since the second filter 11 is a deodorizing filter, the third filter 12 is a formaldehyde removal filter, the fourth filter 13 is a HEPA filter, and the first filter 10 includes a fixed frame 1001, an antibacterial layer 1002, a fine filter layer 1003 and a coarse filter layer 1004, the antibacterial layer 1002, the fine filter layer 1003 and the coarse filter layer 1004 are arranged in sequence from left to right, so that after entering, the air will pass through the first guide plate 16 to better flow to the first filter 10, and then be filtered in sequence by the coarse filter layer 1004, the fine filter layer 1003 and the antibacterial layer 1002, effectively intercepting dust in the air and sterilizing the air. When the sterilized gas is filtered by the second filter 11, the third filter 12 and the fourth filter 13, the bacteria remaining on the second filter 11, the third filter 12 and the fourth filter 13 can be effectively reduced, thereby improving the purification effect, and the filtered air flows out from the exhaust port 3 along the second guide plate 17. Example

[0040] In this embodiment, the first filter screen 10, the second filter screen 11, the third filter screen 12 and the fourth filter screen 13 can be disassembled, cleaned or replaced to ensure the air filtering effect. Figure 2-Figure 3 , Figure 5 and Figure 7 As shown:

[0041] A card slot 9 is provided on the top inner wall of the outer shell 1, and the card slot 9 and the sealing strip 8 are snap-fitted and connected, and the sealing strip 8 is rectangular.

[0042] Limit blocks 14 are installed at the front and rear ends of the first filter 10, the second filter 11, the third filter 12 and the fourth filter 13, and the limit blocks 14 form a sliding structure through the connecting groove 15 and the outer shell 1, and the connecting groove 15 is opened on the inner wall of the outer shell 1, and there is a gap between the connecting groove 15 and the card slot 9.

[0043] A card slot 9 is provided on the top inner wall of the outer shell 1, and the card slot 9 and the sealing strip 8 on the lower surface of the top plate 5 are card-engaged. Therefore, when the filter is in use, the card engagement between the sealing strip 8 and the card slot 9 can make the sealing effect between the outer shell 1 and the top plate 5 better, effectively preventing air leakage. In addition, limit blocks 14 are installed at the front and rear ends of the first filter screen 10, the second filter screen 11, the third filter screen 12 and the fourth filter screen 13, and the limit blocks 14 and the connecting groove 15 are slidably connected. Therefore, it is convenient to disassemble, clean or replace the first filter screen 10, the second filter screen 11, the third filter screen 12 and the fourth filter screen 13, which brings convenience to the operation of the staff and improves the use effect of the filter. The above is the working process of the entire device.
