The other end of the interior of the housing is provided with an adsorption chamber. The adsorption chamber includes two guide plates and an adsorption plate. In this utility model, the particulate matter in the paint mist is first blocked and filtered through the filtration chamber, then the paint mist is secondarily filtered and purified through the spray chamber, and finally the paint mist is deodorized through the adsorption chamber. By setting the filtration chamber, the spray chamber, and the adsorption chamber to filter the paint mist multiple times, the filtration effect of the paint mist is greatly improved, which not only avoids the harm of paint mist to the physical health of workers but also avoids the pollution of paint mist to the environment.

[0004] However, the paint mist filters in the prior art are inconvenient to replace the filter cotton inside them individually. After use, they are directly replaced as a whole, resulting in an increase in cost. Therefore, a combined paint mist filter is needed. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a combined paint mist filter, which solves the problem that the paint mist filter in the prior art is inconvenient to replace the filter cotton inside it individually.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A combined paint mist filter, including a filtration chamber and a buckle mechanism arranged inside the filtration chamber. The buckle mechanism includes a fixing component and a working component;

[0007] The fixing component includes a hinge. The outside of the filtration chamber is fixedly connected with a hinge. The outside of the hinge is fixedly connected with a box cover. The surface of the box cover is fixedly connected with a handle;

[0008] The working component includes a bottom plate. A bottom plate is fixedly connected inside the filtering chamber. A clamping block is rotatably connected to the top end of the bottom plate. An extension block is fixedly connected to the outside of the clamping block. A first spring is fixedly connected to the bottom of the extension block. A buckling block is fixedly connected inside the box cover.

[0009] An installation frame is slidably connected to the inner wall of the filtering chamber. A second spring is fixedly connected inside the installation frame. One end of the second spring is fixedly connected to a top bead. A fixing plate is fixedly connected to the outer wall of the filtering chamber. A retracting shaft penetrates through the surface of the fixing plate. A retaining ring is fixedly connected to the outer wall of the retracting shaft. An air inlet is fixedly connected to one end of the filtering chamber. An air outlet is fixedly connected to the end of the filtering chamber far from the air inlet.

[0010] Preferably, two sets of the clamping blocks, extension blocks and first springs are provided. The positional relationship of the two sets of clamping blocks, extension blocks and first springs is symmetrical about the midpoint of the bottom plate.

[0011] Preferably, the first spring and the bottom plate form a rebounding structure through the extension block.

[0012] Preferably, the box cover and the filtering chamber form an opening and closing structure through the buckling block and the clamping block.

[0013] Preferably, the installation frame and the filtering chamber form a fixing structure through the second spring and the top bead.

[0014] Preferably, the second spring and the installation frame form a rebounding structure through the retracting shaft and the top bead.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0016] 1. By setting to pull the handle forcefully to make the box cover rotate through the hinge, so that the buckling block disengages from the clamping block, the box cover can be opened to the filtering chamber. On the contrary, when it is necessary to close the filtering chamber, make the box cover rotate through the hinge to cover the filtering chamber. At this time, the buckling block will push open the clamping block, so that the extension block and the bottom plate exert pressure on the first spring. When the buckling block is completely clamped into the clamping block, the pressure disappears, and the first spring rebounds to make the clamping block tightly clamp the buckling block, so that the box cover will not be easily affected by the outside world after closing the filtering chamber.

[0017] 2. By setting to press the retracting shaft to push the top bead inward, after the top bead completely slides into the installation frame, the fixed state between the installation frame and the filtering chamber can be unlocked. When a new installation frame is replaced, the top bead will closely adhere to the inner wall of the filtering chamber and squeeze the second spring. Then, after the installation frame is completely clamped into the filtering chamber, the second spring rebounds to make the top bead clamp into the filtering chamber and push out the retracting shaft, so as to lock between the installation frame and the filtering chamber, so that the installation frame can achieve the effects of being convenient for disassembly, replacement and installation, and avoid the problem that the filtering function fails due to the influence of the outside world.

Specific embodiments

[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Embodiment 1

[0025] As Figures 1-4 shown, a combined paint mist filter in the illustration includes a filter chamber 1 and a buckle mechanism disposed inside the filter chamber 1. The buckle mechanism includes a fixing component and a working component;

[0026] The fixing component includes a hinge 2. The hinge 2 is fixedly connected to the outside of the filter chamber 1. The hinge 2 is fixedly connected to the outside of a box cover 3. A handle 4 is fixedly connected to the surface of the box cover 3;

[0027] The working component includes a bottom plate 5. The bottom plate 5 is fixedly connected to the inside of the filter chamber 1. The top end of the bottom plate 5 is rotatably connected to a clamping block 6. An extension block 7 is fixedly connected to the outside of the clamping block 6. A first spring 8 is fixedly connected to the bottom of the extension block 7. A buckle block 9 is fixedly connected to the inside of the box cover 3.

[0028] Among them, as Figure 3As shown, there are two sets of clamping blocks 6, extension blocks 7 and first springs 8. The positional relationship of the two sets of clamping blocks 6, extension blocks 7 and first springs 8 is symmetrical about the midpoint of the bottom plate 5, which is beneficial for the two sets of clamping blocks 6, extension blocks 7 and first springs 8 to make the buckle structure more stable, so that the opening and closing structure between the box cover 3 and the filter chamber 1 is more firm.

[0029] Among them, as Figure 3 shown, the first spring 8 and the bottom plate 5 form a rebounding structure through the extension block 7, which is beneficial for the first spring 8 to tightly clamp the clamping block 6 through the rebounding force, so that the box cover 3 and the filter chamber 1 will not be easily affected by the outside world after being closed.

[0030] Among them, as Figure 3 shown, the box cover 3 and the filter chamber 1 form an opening and closing structure through the buckle block 9 and the clamping block 6, which is beneficial for the box cover 3 to open the filter chamber 1, so as to facilitate the replacement of the filter cotton in the filter chamber 1 by personnel.

[0031] Embodiment 2

[0032] As Figure 1 , Figure 2 and Figure 4 shown, an installation frame 10 is slidably connected to the inner wall of the filter chamber 1. A second spring 11 is fixedly connected inside the installation frame 10. One end of the second spring 11 is fixedly connected with a top bead 12. A fixing plate 13 is fixedly connected to the outer wall of the filter chamber 1. A retracting shaft 14 penetrates through the surface of the fixing plate 13. A retaining ring 15 is fixedly connected to the outer wall of the retracting shaft 14. An air inlet 16 is fixedly connected to one end of the filter chamber 1. An air outlet 17 is fixedly connected to the end of the filter chamber 1 away from the air inlet 16.

[0033] Among them, as Figure 4 shown, the installation frame 10 and the filter chamber 1 form a fixed structure through the second spring 11 and the top bead 12, which is beneficial for the installation frame 10 to be directly locked after being installed in the filter chamber 1, avoiding the problem of being unable to filter due to being affected by the outside world.

[0034] Among them, as Figure 4 shown, the second spring 11 and the installation frame 10 form a rebounding structure through the retracting shaft 14 and the top bead 12, which is beneficial for unlocking the locked state between the installation frame 10 and the filter chamber 1, so as to facilitate the disassembly, replacement and installation of the installation frame 10 quickly and conveniently.

[0035] During use: First, pull the handle 4 forcefully to rotate the box cover 3 through the hinge 2, so that the locking block 9 disengages from the clamping block 6, and then the box cover 3 can be opened to expose the filtering cavity 1. Conversely, when it is necessary to close the filtering cavity 1, rotate the box cover 3 through the hinge 2 to cover the filtering cavity 1. At this time, the locking block 9 will push open the clamping block 6, causing the extension block 7 and the bottom plate 5 to apply pressure to the first spring 8. When the locking block 9 is completely snapped into the clamping block 6, the pressure disappears, and the first spring 8 rebounds to tightly clamp the locking block 9 with the clamping block 6, so that the box cover 3 will not be easily affected by the outside world after closing the filtering cavity 1.

[0036] Finally, press the retracting shaft 14 to push it inward to drive the top bead 12. After the top bead 12 completely slides into the mounting frame 10, the fixed state between the mounting frame 10 and the filtering cavity 1 can be unlocked. After replacing the new mounting frame 10, the top bead 12 will closely adhere to the inner wall of the filtering cavity 1 and compress the second spring 11. Then, after the mounting frame 10 is completely snapped into the filtering cavity 1, the second spring 11 rebounds to make the top bead 12 snap into the filtering cavity 1 and push out the retracting shaft 14, thus locking the mounting frame 10 and the filtering cavity 1, so that the mounting frame 10 can achieve the effect of being convenient for disassembly, replacement and installation, and avoiding the problem that the filtering function fails due to the influence of the outside world.
