[0007] Preferably, the V-shaped or W-shaped opening of the wind deflector below the air inlet is arranged upward, and the V-shaped or W-shaped opening of the wind deflector below the air outlet is arranged downward.

[0008] Preferably, the opening degree of the wind deflector gradually increases from top to bottom.

[0009] Preferably, the front inner wall and the rear inner wall below the box body are provided with paperboards, the paperboards are provided with circular clamping holes, and the wind deflector is fixed in the clamping holes.

[0010] Compared with the prior art, the paint mist filter has the following beneficial effects:

[0011] The utility model sets the wind deflector, intercepts the paint mist in the filter channel, and makes the paint mist adsorbed on the wind deflector to achieve the purpose of filtering the paint mist. The wind deflector is in the shape of V or W as a whole, which increases the contact area of the wind deflector and the paint mist and improves the filtering effect. BRIEF DESCRIPTION OF DRAWINGS

[0016] The following is further detailed through specific implementation:

[0017] The reference signs in the drawings of the specification include: box 1, filter cavity 2, air inlet 3, baffle 4, air deflector 5, paperboard 6, clamping hole 7, air outlet 8.

[0018] As shown in the accompanying Figures 1-4 The embodiment shows a paint mist filter, including box 1, the filter cavity 2 is in box 1, the air inlet 3 and the air outlet 8 are set up on the both sides of box 1, the air inlet 3 and the air outlet 8 all are linked with filter cavity 2, the baffle 4 is set up between the air inlet 3 and the air outlet 8 in box 1, the baffle 4 separates the filter cavity 2 top into air inlet chamber and air outlet chamber, the air deflector 5 is set up below in box 1, and the air deflector 5 is V-shaped as a whole.

[0019] Similarly, the air deflector 5 can also be set to be W-shaped as a whole to ensure the degree of blocking of the air deflector 5 to the exhaust gas.

[0020] The working principle of the paint mist filter of the embodiment is as follows: the paint mist filter is placed in the exhaust gas passage, the exhaust gas enters the filter cavity 2 from the air inlet 3, then encounters the air deflector 5 downward, and then escapes from the air outlet 8 upward. In the process of encountering the air deflector 5, the paint mist in the exhaust gas is adsorbed on the air deflector 5, thereby realizing the filtration of the exhaust gas.

[0021] As Figure 2 The left side is the air inlet chamber, and the right side is the air outlet chamber.

[0022] Among them, in order to increase the degree of blocking of the air deflector 5 to the exhaust gas, the V-shaped opening of the air deflector 5 below the air inlet 3 is set upward, so that the paint mist in the exhaust gas moving downward from the air inlet 3 into the filter cavity 2 fully contacts the V-shaped opening upward air deflector 5, thereby improving the adsorption rate of the paint mist in the exhaust gas and improving the filtration effect. Similarly, the opening of the air deflector 5 below the air outlet 8 is set downward, so that the paint mist in the exhaust gas moving upward after passing through the air inlet chamber fully contacts the opening downward air deflector 5, thereby improving the adsorption rate of the paint mist.

[0023] As Figure 3 shown, the opening degree of the air deflector 5 is gradually increased from top to bottom, which gradually improves the blocking degree of the exhaust gas.

[0024] As Figure 4 shown, the front inner wall and the rear inner wall below the box body 1 are provided with paper boards 6, the paper boards 6 are provided with circular clamping holes 7, and the air deflector 5 is fixed in the clamping holes 7.

[0025] In the above embodiment, the box body 1 is a paper shell box, and the partition plate 4 can be fixed by glue or other common ways. Similarly, the air deflector 5 can also be fixed in the clamping hole 7 by glue.

[0026] The above is only an embodiment of the present application, and the common knowledge of specific structures and characteristics in the scheme is not described in detail. It should be pointed out that for those skilled in the art, without departing from the structure of the present application, a number of modifications and improvements can be made, which should also be considered as the protection scope of the present application, and these will not affect the effect and practicality of the present application. The protection scope of the present application should be subject to the content of its claims, and the specific implementation mode and the like recorded in the specification can be used to explain the content of the claims.
