[0002] The lacquer mist filter is also called a lacquer mist purifier, which is a filtering device mainly applied to a paint spraying workshop. After paint is atomized into particles under the action of high pressure, the lacquer mist is dispersed into the air in the workshop along with the airflow, which may cause workers to inhale the lacquer mist through the respiratory tract, affecting their health. Therefore, the lacquer mist filter is needed to filter the lacquer mist in the air in the workshop to improve the working environment of workers in the workshop and meet the environmental protection requirements.

[0003] In the Chinese invention patent CN114028896A, a lacquer mist filtering box is disclosed, which improves the filtering effect of lacquer mist by setting multiple turbulence layers, prevents the pollution of the environmental protection equipment in the later stage, and reduces the practical cost in the later stage. However, this type of lacquer mist filter has a fast flow rate of lacquer mist, which makes the lacquer mist flow through the lacquer mist filtering box quickly, resulting in a short contact time of the lacquer mist with the filtering unit.

[0018] The embodiments of the present disclosure are described in detail below with reference to the drawings.

[0019] The following detailed description of the application is provided as an example for the purpose of enabling those skilled in the art to practice the application. The application, however, is not intended to be limited to the embodiments described herein, but instead is to be accorded the full scope consistent with the claims, to embody all legal equivalents. Various embodiments of the application will now be described, by way of example only, with reference to the drawings:-

[0020] Reference Figs. 1-2 , Fig. 1 is a structural schematic diagram of the utility model; Fig. 2 is a structural schematic diagram of the filter unit of the utility model. A paint mist filter comprises a box body 11 and a filter unit 12, the filter unit 12 is arranged in the box body 11 and adsorbs paint mist particles in the air, one end of the box body 11 is provided with an air inlet 111, and the air is injected into the inner cavity of the box body 11 through the air inlet 111, the other end of the box body 11 is provided with an air outlet 112, and the filtered air is discharged outwardly through the air outlet 112, and the filter unit 12 is arranged in five groups from the direction of the air inlet 111 to the direction of the air outlet 112, and the orientation and arrangement mode of each group of filter units 12 are different.

[0021] The paint mist filter, by arranging five groups of filter units 12 with different orientations and arrangement modes, can make the paint mist flow into the paint mist filter quickly first, and then form a vortex airflow in the paint mist filter under the blocking and guiding effect of the subsequent groups of filter units 12, thereby reducing the discharge rate of the paint mist from the paint mist filter and circulating in the paint mist filter, so that the paint mist particles in the air are completely adsorbed by the filter units 12 before being discharged, improving the filtering quality and avoiding the situation that the paint mist flows too fast, which can cause the paint mist to contact the filter units 12 for a short time, resulting in incomplete filtering and affecting the paint mist filtering effect.

[0022] The filter unit 12 is an equilateral triangle, and always has one corner facing the air outlet 112 or the air inlet 111.

[0023] The filter unit 12 comprises a first filter piece 121, a second filter piece 122, a third filter piece 123, a fourth filter piece 124 and a fifth filter piece 125, and the air is filtered in the order of the first filter piece 121, the second filter piece 122, the third filter piece 123, the fourth filter piece 124 and the fifth filter piece 125 during the process of flowing from the air inlet 111 to the air outlet 112.

[0024] The plurality of first filter pieces 121 are connected to the box 11, and one corner of one of the plurality of first filter pieces 121 is opposite the air inlet 111, the plurality of second filter pieces 122 are connected to the box 11, and one corner of two second filter pieces 122 located at the ends is opposite the air inlet 111, and one corner of the plurality of second filter pieces 122 located in the middle is opposite the air outlet 112, and the plurality of third filter pieces 123 are connected to the box 11.

[0025] One corner of the plurality of third filter pieces 123 is opposite the air outlet 112, so that after the air is injected into the paint mist filter, the air can be guided under the action of the first filter pieces 121, part of the air passes through the first filter pieces 121 for filtering, most of the air passes through the gaps between the first filter pieces 121 to flow backward, and is blocked by the horizontal surface of the second filter pieces 122 in the middle for filtering, and part of the air is guided by the two end second filter pieces 122, and then is blocked by the back surface of the third filter pieces 123 which are all directed to the air outlet 112 for filtering, so that the air can reduce the resistance when flowing through the first filter pieces 121, the second filter pieces 122 and the third filter pieces 123, and more effectively capture the paint particles in the air.

[0026] The plurality of fourth filter pieces 124 are connected to the box 11, and one corner of the plurality of fourth filter pieces 124 is opposite the air inlet 111, and the number of the fourth filter pieces 124 is two groups, so that the air can be divided and then combined when flowing through the two groups of fourth filter pieces 124, thereby making the air fully contact the filtering unit 12 and improving the filtering efficiency.

[0027] The plurality of fifth filter pieces 125 are connected to the box 11, and the plurality of fifth filter pieces 125 are alternately arranged from one end to the other end, so that the fifth filter pieces 125 form a block with only a small gap to make the air flow, thereby reducing the air exhaust efficiency, making the air form a vortex flow in the box 11, and filtering multiple times, thereby improving the filtering capacity of the paint mist particles in the air.
