In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0029] In addition, the technical features involved in different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0030] As Figure 1 and Figure 2 and Figure 3 shown, it includes a box body 1 and a fan 2. The fan 2 is arranged inside the box body 1. The fan 2 is used for inhaling and exhaling air. A cover plate 3 is arranged at the air inlet of the box body 1. A plurality of air inlet holes 30 are arranged on the cover plate 3. A filter unit 4 is arranged at the air outlet of the box body 1. The filter unit 4 adopts a filter. The gas enters through the air inlet holes 30, is adsorbed by the fan 2, then comes out from the fan 2, passes through the filter unit 4, and fresh air flows out.

[0031] The suction end of the fan 2 is aligned with multiple air inlet holes 30. The fan 2 is located between the cover plate 3 and the filter unit 4. The air coming out of the air outlet end of the fan 2 flows towards both sides of the box body 1.

[0032] On both sides inside the box body 1, a first air guide plate 11 and a second air guide plate 12 are respectively inclined. The first air guide plate 11 and the second air guide plate 12 are arranged oppositely. During use, the cover plate 3 is at the top. The upper ends of the first air guide plate 11 and the second air guide plate 12 are far away from each other, that is, the first air guide plate 11 and the second air guide plate 12 are more separated when approaching the cover plate 3, and the lower ends are close to each other. Both the first air guide plate 11 and the second air guide plate 12 are located on the air flow channel of the fan 2. In this way, the gases flowing towards both sides are respectively blocked by the first air guide plate 11 and the second air guide plate 12, and the accumulated gases still need to descend. At the same time, the lower ends of the first air guide plate 11 and the second air guide plate 12 are close to each other, that is, the gases are concentrated.

[0033] The downward extending ends of the first air guide plate 11 and the second air guide plate 12 abut against the filter unit 4. During use, the filter unit 4 is at the bottom. In this way, the concentrated gases flow out from the filter unit 4, and fresh air flows out.

[0034] A support plate 5 is arranged inside the box body 1. The fan 2 is arranged on the support plate 5 and the inner wall of the box body 1. The first air guide plate 11 and the second air guide plate 12 are respectively located on both sides of the support plate 5. During normal use, the gases flow towards both sides of the support plate 5. The support plate 5 is located directly above the filter unit 4. Because the fan 2 always sends air into the box body 1, the accumulated gases flow towards the filter unit 4 and flow out from the filter unit 4. The support plate 5 is laid flat in the middle of the box body 1, and channels are formed on both sides of the support plate 5 to enable the gases to flow towards the first air guide plate 11 and the second air guide plate 12 respectively.

[0035] A reinforcing plate 6 is attached to the surface of the support plate 5. The reinforcing plate 6 is located on the lower surface of the support plate 5. The outer periphery of the reinforcing plate 6 has a surrounding wall 61. The height direction of the surrounding wall 61 is perpendicular to the reinforcing plate 6. The surrounding wall 61 extends towards the filter unit 4. The fan 2 is arranged on both the support plate 5 and the reinforcing plate 6 at the same time. The support plate 5 and the reinforcing plate 6 jointly support the fan 2. The reinforcing plate 6 can increase the thickness of the support of the support plate 5. When the support plate 5 and the reinforcing plate 6 are about to bend, the surrounding wall 61 can prevent bending.

[0036] Through holes 62 and multiple fixing holes 63 are arranged on the reinforcing plate 6. The size of the through holes 62 is larger than that of the fixing holes 63. The through holes 62 communicate with the multiple fixing holes 63. The through holes 62 and the fixing holes 63 are used for installing and fixing the fan 2. A groove 64 is arranged on the surrounding wall 61. The groove 64 is used for the cable to pass through. Actually, it is used for the cable on the fan 2 to pass through to prevent the cable from bending the surrounding wall 61.

[0037] The two sides of the support plate 5 are bent to form a first reinforcing strip 51 and a second reinforcing strip 52. The first reinforcing strip 51 is close to the first air guide plate 11, and the second reinforcing strip 52 is close to the second air guide plate 12.

[0038] A plurality of first air guide holes 110 are provided on the first air guide plate 11, and a plurality of second air guide holes 120 are provided on the second air guide plate 12. As the filtering unit 4 filters more gas, the filtering unit 4 will become blocked, and the flow rate of the gas collected centrally through the middle of the filtering unit 4 will become slower and slower. The excess gas will respectively pass through the first air guide holes 110 and the second air guide holes 120, so that the excess gas is filtered from both sides of the filtering unit 4.

[0039] The air outlet of the box body 1 has a flange 10. The flange 10 is located inside the air outlet of the box body 1. The filtering unit 4 is embedded in the flange 10. The first air guide plate 11 has a first overlapping strip 111. The first overlapping strip 111 is integrally formed with the first air guide plate 11, and there is an angle between the first overlapping strip 111 and the first air guide plate 11. The second air guide hole 120 has a second overlapping strip 121. The second overlapping strip 121 is integrally formed with the second air guide hole 120, and there is an angle between the second overlapping strip 121 and the second air guide hole 120. The first overlapping strip 111 and the second overlapping strip 121 overlap on the flange 10. Actually, the first overlapping strip 111 and the second overlapping strip 121 overlap on the upper surface of the flange 10.

[0040] Guide strips 7 are provided on the inner wall at the air inlet of the box body 1. There are two guide strips 7 symmetrically arranged. The upper part of the fan 2 is suspended on the inner wall of the box body 1. Therefore, the guide strips 7 play a supporting role to prevent the upper shell of the box body 1 from bending. The guide strip 7 includes a first side strip 71 and a second side strip 72 which are integrally formed. There is an angle between the first side strip 71 and the second side strip 72. In this way, both the first side strip 71 and the second side strip 72 are inclined. The first side strip 71 can also play a guiding role, and the gas flows obliquely downward along the first side strip 71.

[0041] The outer periphery of the cover plate 3 has a retaining wall 31. The retaining wall 31 abuts against the outer surface of the box body 1. The area enclosed by the retaining wall 31 forms an air duct. When the fan 2 sucks air, the air is sucked into the area enclosed by the retaining wall 31. The retaining wall 31 has a lap edge 32 extending towards the periphery. The lap edge 32 fits against the outer surface of the box body 1 to form a seal, so that the gas in the box body 1 cannot leak out.

[0042] Fixing pieces 8 with right angles are provided at the top corners of the box body 1. Fixing pieces 8 are provided at the four top corners of the side where the filtering unit 4 is located. The fixing pieces 8 are used to connect other devices, so that the fixing pieces 8 are clamped on the four top corners of other devices, which not only plays a fixing role but also a limiting role.

[0043] As Figure 4As shown, the fan 2 includes a first housing 21, a second housing 22, a motor 23 and blades 24. The first housing 21 and the second housing 22 are fixed together by a connecting rod 25. The motor 23 is arranged on the second housing 22. The driving end of the motor 23 passes through the second housing 22. The blades 24 are connected to the driving end of the motor 23. The middle of the first housing 21 is hollowed out, and the hollowed-out area in the middle of the first housing 21 is aligned with the air inlet hole 30.
