[0028] Embodiment 2

[0029] See also Figure 1-5 On the basis of Embodiment 1, the utility model provides a technical solution: preferably, a cartridge cover 4 is connected to the top of the base 1, and the cartridge cover 4 provides protection for the filter cartridge 2. The filter cartridge 2 is mounted on the top of the base 1, and the filter cartridge 2 is located inside the cartridge cover 4. The cartridge cover 4 is opened at one end away from the base 1, and the opening of the cartridge cover 4 is convenient for pouring out and cleaning the accumulated dust. A sealing plate 5 is installed on the open end of the cartridge cover 4, and an air inlet 6 is connected to the sealing plate 5. An air exhaust port 7 is provided on the base 1, and a mounting groove is provided at the bottom of the base 1. A threaded groove 8 is provided at the bottom of the base 1, and the base 1 can be threadedly mounted on the equipment through the threaded groove 8. A negative pressure fan 9 is installed on the inner wall of the mounting groove, and the mounting groove protects the negative pressure fan 9. The air inlet end of the negative pressure fan 9 passes through the inner wall of the air exhaust port 7, and the mounting plate 31 is connected between the inner walls of the cartridge cover 4.

[0030] In this embodiment, dust can be stored and collected in the gap between the cartridge cover 4 and the filter cartridge 2 to prevent the filtered dust from invading the negative pressure fan 9 and reducing the filtration quality, thereby facilitating centralized dust cleaning. Threaded installation is used to improve tightness and avoid installation shaking. No extra gap is generated, thereby improving the filtration quality. The cartridge cover 4 can also provide protection for the filter cartridge 2, thereby extending its service life.

[0031] Working principle: the base 1 provides a stable supporting force for the filter cartridge 2, and the base 1 can be threadedly installed on the equipment through the threaded groove 8. The installation method is simple, and can directly play the role of stabilizing the installation base 1, preventing the problem of the entire device falling off the equipment during filtration, and improving the safety of use. The negative pressure fan 9 is built into the installation groove of the base 1, which plays a role in protecting the negative pressure fan 9. The negative pressure fan 9 is a kind of pump machine, which is a prior art and therefore will not be described in detail. By starting the negative pressure fan 9, the air inlet end of the negative pressure fan 9 generates negative pressure suction, and the air is sucked through the air suction port 7. At the same time, negative pressure is generated in the cylinder cover 4, and the air is sucked into the filter cartridge 2 through the air inlet 6. The cylinder cover 4 performs external protection on the filter cartridge 2. At the same time, the gap between the cylinder cover 4 and the filter cartridge 2 can be used to store and collect dust, so as to prevent the filtered dust from invading the negative pressure fan 9 and reducing the filtration quality, thereby facilitating centralized dust cleaning. The rotating rod 32 is limited by the mounting plate 31, and the negative pressure suction is used to generate power, and the fan blades 33 are prompted to drive the rotating rod. The second scraper arm 37 is driven by the second connecting rod 36 to rotate around the outer wall of the filter cartridge 2 to scrape the dust on the outer wall of the filter cartridge 2, thereby always maintaining the cleaning effect of the filter cartridge 2 during filtration and improving the cleanliness of the filter cartridge 2. The sealing plate 5 and the barrel cover 4 are detachably installed in the form of threaded installation. When the machine is shut down, the sealing plate 5 can be opened to expose the opening of the barrel cover 4, so that the accumulated dust can be poured out and cleaned from the inner wall of the filter cartridge 2 and the gap area between the barrel cover 4 and the filter cartridge 2, so as to facilitate dust cleaning. The above steps can allow the filter cartridge 2 to use negative pressure as a driving force during use to conveniently clean adhered dust, avoid the phenomenon of filter blockage, and improve the filtration efficiency. At the same time, the threaded installation is used to improve the tightness, avoid the problem of installation shaking, and no unnecessary gap will be generated, thereby improving the filtration quality. The barrel cover 4 can also provide protection for the filter cartridge 2, thereby extending the service life.
