[0022] 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.

[0023] Please see Figure 1-3 This utility model provides a technical solution:

[0024] Example 1

[0025] Regarding the aforementioned problem 1: the existing ventilation hood's filter components have a slow air filtration speed and do not fully filter impurities in the air, affecting its use.

[0026] The solution is as follows: A ventilation hood with a filter assembly includes a device body 1. The device body 1 includes a filter hood 2, a ventilation diversion hood 3, and a filter device 4. The ventilation diversion hood 3 is installed on top of the filter hood 2, and the filter device 4 is installed inside the filter hood 2. The filter device 4 includes a first sliding block 5, a second sliding block 6, a large-pore filter plate 7, a medium-pore filter plate 8, and a small-pore filter plate 9. The first sliding block 5 is located at the rear end of the second sliding block 6. Both the first sliding block 5 and the second sliding block 6 have a V-shaped structure. The large-pore filter plate 7, the medium-pore filter plate 8, and the small-pore filter plate 9 are all installed between the first sliding block 5 and the second sliding block 6. The large-pore filter plate 7 is located below the medium-pore filter plate 8, and the small-pore filter plate 9 is located... Above the perforated filter plate 8, the large-pore filter plate 7, the medium-pore filter plate 8, and the small-pore filter plate 9 all have a V-shaped structure. The front end of the first sliding block 5 is provided with a push-pull handle 10. In use, the connecting frame 15 at the bottom of the filter cover 2 is connected to the equipment. Then the equipment discharges gas into the filter cover 2. The gas passes through the filter device 4. The large-pore filter plate 7 in the filter device 4 filters out larger impurities in the gas. Then the medium-pore filter plate 8 filters out medium-sized impurities in the air. Finally, the air passes through the small-pore filter plate 9, which filters out smaller and larger impurities in the gas. The large-pore filter plate 7, the medium-pore filter plate 8, and the small-pore filter plate 9 all have a V-shaped structure, which facilitates the concentration of airflow, thereby improving the filtration speed and filtration effect.

[0027] The filter cover 2 has an embedded frame 12 at the top, and the surface of the embedded frame 12 has several sets of fixing holes 13 distributed horizontally at equal intervals. The filter cover 2 has a connecting frame 15 at the bottom, and the bottom of the connecting frame 15 has a connecting sealing gasket 16. The connecting sealing gasket 16 is made of rubber. Fixing holes 13 are opened at the four corners of the connecting frame 15. The embedded frame 12 at the top of the filter cover 2 can be inserted into the main diversion pipe 17, and then screws are inserted into the fixing holes 13 to fix the filter cover 2 and the ventilation diversion cover 3.

[0028] The ventilation diversion hood 3 has a T-shaped structure and includes a main diversion pipe 17, a first diversion pipe 18, and a second diversion pipe 19. The first diversion pipe 18 is installed on the top left side of the main diversion pipe 17, and the second diversion pipe 19 is installed on the top right side of the main diversion pipe 17. The main diversion pipe 17, the first diversion pipe 18, and the second diversion pipe 19 are connected in a continuous structure. Several sets of fixing holes 13 are opened on the outer side of the bottom of the main diversion pipe 17, and the filtered gas can be discharged and used through the first diversion pipe 18 and the second diversion pipe 19.

[0029] A diversion plate 20 is provided between the first diversion pipe 18 and the second diversion pipe 19. The diversion plate 20 has a Y-shaped structure. The filtered gas can be diverted into the first diversion pipe 18 and the second diversion pipe 19 through the diversion plate 20 between the first diversion pipe 18 and the second diversion pipe 19 for discharge, thereby achieving the purpose of diversion.

[0030] Example 2

[0031] Regarding the second problem to be solved above: the existing ventilation hood's filter components are inconvenient to maintain, and it is difficult to remove, replace, and install them from inside the ventilation hood during maintenance.

[0032] The solution is as follows: The filter cover 2 has a rectangular structure, and the surface of the filter cover 2 has an installation port 14 with a V-shaped structure. The filter cover 2 has a set of symmetrically distributed sliding rails 11 inside. When maintaining the filter device 4, the operator grasps the push-pull handle 10 of the installation port 14 and pulls it out. The first sliding block 5 and the second sliding block 6 of the filter device 4 can then slide out within the set of sliding rails 11, thereby disassembling the filter device 4. After maintenance, the filter device 4 is reinserted into the set of sliding rails 11.

[0033] Working principle: During operation, the connecting frame 15 at the bottom of the filter cover 2 is connected to the equipment. The equipment then discharges gas into the filter cover 2. The gas passes through the filter device 4, where the large-pore filter plate 7 filters out larger impurities. Then, the medium-pore filter plate 8 filters out medium-sized impurities. Finally, the air passes through the small-pore filter plate 9, which filters out smaller and larger impurities. The large-pore filter plate 7, medium-pore filter plate 8, and small-pore filter plate 9 all have a V-shaped structure, which facilitates airflow concentration, thereby improving filtration speed and efficiency. Guided by the diversion plate 20 between the first diversion pipe 18 and the second diversion pipe 19, the filtered gas can be diverted to the first diversion pipe 18 and the second diversion pipe 19 for discharge, thereby achieving the purpose of diversion. When maintaining the filter device 4, the operator grasps the push-pull handle 10 of the installation port 14 and pulls it out. The first sliding block 5 and the second sliding block 6 of the filter device 4 can then slide out in a set of sliding rails 11, thereby disassembling the filter device 4. After maintenance, the filter device 4 is reinserted into a set of moving sliding rails 11.

[0034] The present invention comprises: 1. Device body; 2. Filter cover; 3. Ventilation diversion cover; 4. Filtering device; 5. First sliding block; 6. Second sliding block; 7. Large-hole filter plate; 8. Medium-hole filter plate; 9. Small-hole filter plate; 10. Push-pull handle; 11. Sliding track; 12. Embedded frame; 13. Fixing hole; 14. Mounting port; 15. Connecting frame; 16. Connecting sealing gasket; 17. Main diversion pipe; 18. First diversion pipe; 19. Second diversion pipe; 20. Diversion plate. All components are general standard parts or parts known to those skilled in the art. Their structure and principles can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this invention is that the existing ventilation hood's filter assembly has a slow air filtration speed and incomplete filtration of impurities in the air, affecting its use. This invention, through the combination of the above components, can effectively filter impurities in the gas and also increase the speed at which the gas passes through the filter assembly.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
