[0031] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] See also Figure 1 Combination Figure 2-Figure 7 As shown, the embodiment of the present invention includes:

[0033] A paint mist filtering box with a paint mist filtering structure comprises a paint mist filtering structure 1 and a paint mist filtering box 2 outside the structure.

[0034] Among them, Figure 1-Figure 2 As shown, the paint mist filtering structure 1 is arranged in a three-dimensional structure, including a collision adsorption area 11 and a filtering area 12 which are arranged in sequence in the forward direction of the airflow 3.

[0035] A collision adsorption area 11 is set at the front end of the flow direction of the airflow 3, and the collision adsorption area 11 includes at least two rows of V-shaped plates 111 distributed in an array. The opening direction of the V-shaped plates 111 is opposite to the forward direction of the airflow 3. Two adjacent rows of V-shaped plates 111 are staggered in the forward direction of the airflow 3. In the forward direction of the airflow 3, the distance between the two adjacent rows of V-shaped plates 111 gradually decreases, the width of the V-shaped plates 111 gradually increases, and the opening angle of the V-shaped plates 111 gradually increases. Using a simple V-shaped plate 111 made of corrugated cardboard, a complex structure with gradually increasing paint mist filtration efficiency is achieved through changes in opening and spatial arrangement, which increases the paint capacity compared to traditional honeycomb cartons.

[0036] In the present application, the V-shaped plates 111 are arranged in three rows. In the advancing direction of the airflow 3, the first row and the third row are arranged in three rows, and the second row is arranged in two rows. The V-shaped plates 111 in the first row and the second row, and the V-shaped plates 111 in the second row and the third row are arranged alternately in the advancing direction of the airflow 3. In the advancing direction of the airflow 3, the distance H1 between the first row and the second row of V-shaped plates 111, and the distance H2 between the second row and the third row of V-shaped plates 111 gradually decrease, that is, H1>H2, and the width W1 of the first row of V-shaped plates 111, the width W2 of the second row of V-shaped plates 111, and the width W3 of the third row of V-shaped plates 111 gradually increase, that is, W1>H2. <W2<W3。

[0037] A filter area 12 is provided at the rear end, and the filter area 12 is composed of a porous filter material through an S-shaped reciprocating structure. The material of the filter area 12 is a multi-layer structure composed of a honeycomb paper net and fiber filter cotton. Compared with the traditional maze carton, the paint mist filtering efficiency is improved.

[0038] The paint mist filter box 2 has an outer contour of a rectangular parallelepiped, and in the forward direction of the airflow 3, two opposite sides of the paint mist filter box 2 include an airflow inlet opening 21 and an airflow outlet opening 22 for the entry and exit of paint mist. The paint mist filter box 2 is made of corrugated cardboard, which is easy to manufacture. Example

[0039] like Figure 3-Figure 5 As shown, the outer contour of the paint mist filter box 2 is a cube, and the inner volume of the paint mist filter box 2 is closely matched with the paint mist filter structure 1 arranged in a three-dimensional structure. Example

[0040] like Figure 6-Figure 7As shown, the paint mist filter box 2 is formed by stacking two independent rectangular parallelepipeds, the edges of the fitting surfaces are connected by pressing or gluing and sealing, and an air flow opening 23 is formed in the middle. The internal volumes of the two paint mist filter boxes 2 are closely matched with the collision adsorption area 11 and the filtration area 12 respectively. When the paint mist filter box 2 is too large in size along the direction of the incoming airflow 3, the collision adsorption area 11 and the filtration area 12 can be assembled separately and then combined to form an integral paint mist filter box 2, reducing the difficulty of assembly. In addition, the edges of the fitting surfaces of the two separate rectangular parallelepiped paint mist filter boxes 2 can act as reinforcing ribs to enhance the overall rigidity of the paint mist filter box 2.

[0041] In summary, the paint mist filter box with a paint mist filtering structure pointed out by the present invention increases the paint capacity, is less likely to be clogged, extends the service life, improves the paint mist filtering efficiency, ensures a smaller area volume under the same filtering efficiency, reduces the difficulty of processing and assembly, and reduces the number of spare parts.
