[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 8 As shown, this embodiment provides a leak-proof sealing structure between the air outlet and the filter, including ribs 6 disposed on the inner wall of the housing 5, and rollers on the side of the ribs 6 facing the filter 8. The rollers reduce the contact area between the filter 8 and the ribs 6, thereby improving the sealing performance of the contact surface and achieving a leak-proof sealing effect.

[0031] In this specific embodiment, a sponge pad 7 is provided between the rib 6 and the filter 8. The high elasticity of the sponge pad 7 further improves the sealing performance between the filter 8 and the rib 6, enhancing the leak-proof sealing effect.

[0032] A clamping assembly is provided on the inner wall of the housing 5. The clamping assembly is used to make the filter 8 fit tightly against the roller.

[0033] The clamping assembly includes a first nut, a first screw 10, and a pressure block 9. The first nut is fixedly installed on the inner wall of the housing 5. One end of the pressure block 9 is provided with a through hole. The first screw 10 passes through the through hole and is threadedly connected to the first nut. The other end of the pressure block 9 is used to contact the side of the filter 8 away from the rib 6.

[0034] By tightening the first screw 10, the pressure block 9 presses the filter 8, which in turn causes the filter 8 to squeeze the sponge pad 7, improving the sealing between the filter 8 and the rib 6, further enhancing the leak-proof sealing effect, and preventing vibration during the operation of the air supply equipment from affecting the sealing effect.

[0035] The box 5 is provided with an air inlet 1 on one side, and an air outlet 2 on the other side, and a filter 8 is located between the air inlet 1 and the air outlet 2. The box 5 is provided with a flange 3 on one side, and a flow uniforming plate 4 is arranged in the box 5 and connected with the flange 3.

[0036] The box 5 is provided with a flow distributing plate 11 on one side of the air outlet 2. The box 5 is provided with a second nut, and the flow distributing plate 11 is provided with a mounting hole. The flow distributing plate 11 is mounted on the box 5 by penetrating the second screw 12 through the mounting hole and screwing into the second nut.
