[0035] Reference Figure 1-8 ,

[0036] Example 1

[0037] A purifier with a detachable filter cartridge, the air purifier comprises a bracket 1, a filter box 2, a plurality of filter cartridges 3 and a mounting member 4. The mounting member 4 is a plate. A slot 5, a passage groove 6 and an embedding groove 7 are formed on the mounting member 4. The slot 5 matches the shape of the filter cartridge 3 so that the filter cartridge 3 can be inserted into and pass through the slot 5. A clamp 8 is provided at the open end of the filter cartridge 3. The clamp 8 can pass through the passage groove 6 and can be embedded in the embedding groove 7. The clamp 8 is a block. The embedding groove 7 is different from the passage groove 6. The number of the clamps 8 and the passage groove 6 is the same. In this embodiment, two clamps 8 and two passage grooves 6 are preferably provided. The clamp 8 is fixed to the filter cartridge 3. When the filter cartridge 3 is inserted into the slot 5, the clamp 8 is aligned with the passage groove 6, and then the filter cartridge 3 is pushed upward. The filter cartridge 3 and the clamp 8 move upward, and the clamp 8 moves to the top of the mounting member 4, and the clamp 8 is separated from the mounting member 4. The filter cartridge 3 is then rotated to align the clamping member 8 with the embedding groove 7. The clamping member 8 is released, and the clamping member 8 falls downward into the embedding groove 7 under its own weight. The clamping member 8 is locked into the embedding groove 7, restricting the rotational freedom of the filter cartridge 3. Specifically, the clamping member 8 is tightly pressed against multiple sidewalls of the embedding groove 7.

[0038] A filter chamber 17, an air inlet 18 and an air outlet 19 are formed in the filter box 2. The bracket 1 and the filter box 2 are fixed together by welding, wherein the bracket 1 is in contact with the ground, so that the filter box 2 is suspended relative to the ground, forming an air intake area. The air intake area is connected to the air inlet 18. The air inlet 18, the filter chamber 17 and the air outlet 19 are connected in sequence. Among them, the air outlet 19 is externally connected to a pump body and a pipeline, and the air in the air intake area passes through the air inlet 18, the filter chamber 17 and the air outlet 19 in sequence under the action of the pump body through the pump body and the pipeline. The air enters the air inlet 18 from the air intake area formed below the filter box 2, is filtered by the filter cartridge 3 in the filter chamber 17, and is then discharged through the air outlet 19 of the filter box 2 for air filtration.

[0039] Specifically, the purifier with a detachable filter cartridge further includes an elastic member 9, which in this embodiment is an elastic rubber pad. The elastic member 9 is used to press the filter cartridge 3 and the clamping member 8 together when the clamping member 8 is embedded in the embedding groove 7. When the filter cartridge 3 is inserted into the slot 5, the open end of the filter cartridge 3 abuts against one side of the elastic member 9. The filter cartridge 3 is then pushed upward, and the upward movement of the filter cartridge 3 causes the elastic member 9 to deform until the clamping member 8 on the filter cartridge 3 is separated from the mounting member 4. The filter cartridge 3 is then rotated until the clamping member 8 is aligned with the embedding groove 7. The elastic member 9 exerts a downward force on the open end of the filter cartridge 3, causing the clamping member 8 on the filter cartridge 3 to embed in the embedding groove 7. The elastic member 9 presses the filter cartridge 3 against the top of the filter cartridge 3, thereby securing the filter cartridge 3.

[0040] Specifically, the purifier with a removable filter cartridge further includes a fixing plate 16. Fixing plate 16 is used to mount the elastic member 9. Specifically, the side of the elastic member 9 facing away from the filter cartridge 3 is mounted on fixing plate 16, which is disposed on mounting member 4. Fixing plate 16 is provided to mount the elastic member 9 so that, when subjected to force, the elastic member 9 exerts a force in the opposite direction of the force applied by the elastic member 9. This force causes one side of the elastic member 9 to abut against the open end of the filter cartridge 3, thereby securing the filter cartridge 3.

[0041] A first ventilation groove is formed in the elastic rubber pad, and a second ventilation groove is formed in the fixing plate 16; the position of the first ventilation groove matches the position of the second ventilation groove. Air passes through the filter screen 20, the filter cartridge 3, the passage groove 6, the first ventilation groove, the second ventilation groove, the filter chamber 17, and the air outlet 19 in sequence. The first and second ventilation grooves allow filtered air to pass through the elastic rubber pad and fixing plate 16 in sequence and enter the air outlet 19.

[0042] A buffer pad 15 is provided on the edge of the filter cartridge 3. When the filter cartridge 3 is inserted into the slot 5, the buffer pad 15 abuts against the inner wall surface of the slot 5. The buffer pad 15 is provided to avoid the vibration of the filter box 2 during use, which may cause certain damage to the contact surface of the filter cartridge 3 and the mounting part 4.

[0043] A filter 20 is provided at the air inlet 18. The filter 20 can filter out fine particles such as dust, pollen, and smoke from the air. The filter 20 is detachably connected to the filter housing 2. Prolonged use can lead to a large amount of contaminants on the filter 20. The detachable connection allows the filter 20 to be cleaned.

[0044] The air inlet 18 is located below the filter housing 2. Specifically, it is located at the junction of the bracket 1 and the filter housing 2, below the filter screen 20. The air outlet 19 is located on the side of the filter housing 2. The air intake direction of the air inlet 18 is perpendicular to the air outlet direction of the air outlet 19. Since dust and impurities are heavier than air, they are generally located at a lower altitude. The downward-facing air inlet 18 better filters dust and impurities. The air outlet 19 is located on the side of the filter housing 2, which simplifies installation compared to locating the air outlet 19 on the top of the filter housing 2.

[0045] Example 2

[0046] The difference from Example 1 is that the elastic member 9 further includes a clamping plate 12, a sliding plate 13, and a spring 14. Both the clamping plate 12 and the sliding plate 13 are annular plates. The spring 14 is disposed between the clamping plate 12 and the sliding plate 13. The sliding plate 13 is configured to abut against the filter cartridge 3 and the clamping member 8. The clamping plate 12 is secured to a fixing plate 16. When the filter cartridge 3 is inserted into the slot 5, the open end of the filter cartridge 3 will abut against the sliding plate 13, and then continue to push the filter cartridge 3 upward. The filter cartridge 3 moves upward so that the spring 14 is compressed and deformed until the clamping member 8 on the filter cartridge 3 is separated from the mounting member 4. Then the filter cartridge 3 is rotated until the clamping member 8 is aligned with the embedding groove 7. The filter cartridge 3 will be subjected to the downward force applied by the spring 14 to the sliding plate 13, and then the downward force applied to the open end of the filter cartridge 3 will cause the clamping member 8 on the filter cartridge 3 to be embedded in the embedding groove 7. The fixing plate 16, the spring 14 and the sliding plate 13 will cooperate to press the filter cartridge 3 above the filter cartridge 3, thereby fixing the filter cartridge 3.
