[0021] As shown in Figure 1 - Figure 5As shown, the filter core base 3, the fixed convex ring one 4, the fixed convex ring two 11 and the plurality of hook-shaped pieces 5 are integrally formed, and the forming mode can be plastic injection molding. The insertion port on the filter core base 3 can be milled by milling the formed filter core base 3, and the milling tool is a T-shaped tool, so that the vertical cross-sectional shape of the insertion port is in the shape of a convex character. The filter core top cover 1, the filter core base 3, the fixed convex ring one 4, the fixed convex ring two 11 and the plurality of hook-shaped pieces 5 are all made of PVC material, which has good corrosion resistance, heat resistance, flame resistance and good mechanical properties, ensuring that the filter core has good structural strength. The end surface of the filter core base 3 is also provided with an exhaust port 301 for discharging clean air filtered by the filter core. A sealing ring 9 is arranged on the bottom surface of the filter core base 3 to ensure that the connection between the filter core and the main body of the dust collector is tight and leak-free, further improving the filtering effect. The fixed convex ring one 4 and the fixed convex ring two 11 are coaxial and circular, and the diameter of the fixed convex ring one 4 is greater than that of the fixed convex ring two 11. The fixed convex ring one 4 and the fixed convex ring two 11 form a containing groove on the filter core base 3 for accommodating the bottom of the filter core body 2. The filter core body 2 is mainly a filter material, and the connection between the filter core body 2 and the filter core base 3 and the filter core top cover 1 can be by adhesion or clamping.
[0022] The plurality of hook-shaped pieces 5 are arranged in a circumferential array on the outer peripheral wall of the fixed convex ring one 4.

One end of the long side of the hook-shaped piece 5 is fixedly connected to the outer peripheral wall of the fixed convex ring one 4, and the other end of the short side is close to the top surface of the filter core base 3. The other end of the short side of the hook-shaped piece 5 is spaced from the outer peripheral wall of the fixed convex ring one 4. During the sleeving process of the non-woven fabric net sleeve 8, the elastic rib 801 of the non-woven fabric net sleeve 8 is contracted and fitted on the outer peripheral wall of the fixed convex ring one 4. When the non-woven fabric net sleeve 8 is displaced up and down, the elastic rib 801 of the non-woven fabric net sleeve 8 enters the groove inside the hook-shaped piece 5, reducing the possibility of the non-woven fabric net sleeve 8 detaching from the filter core. Preferably, the number of hook-shaped pieces 5 is 4-12. By increasing the number of hook-shaped pieces 5 and arranging them in a circumferential array, the fixing effect of the hook-shaped pieces 5 on the non-woven fabric net sleeve 8 is improved, and the possibility of detachment is reduced.
[0023] The insertion port comprises a containing groove 6 extending from the outer peripheral wall of the filter core base 3 to the direction of the fixed convex ring 4 and an exposed groove 10 located above the containing groove 6 and communicating with the containing groove 6, the exposed groove 10 penetrating through the top of the filter core base 3 to the containing groove 6, and the vertical section of the combination of the containing groove 6 and the exposed groove 10 is in the shape of a convex letter. When the magic tape 7 is inserted, the magic tape 7 can be clamped, and the possibility of the magic tape 7 falling off after being inserted into the insertion port is reduced. The insertion port is mainly used for inserting the magic tape 7 into the insertion port. The magic tape 7 is divided into a hook surface and a fuzzy surface, a plurality of hard hooks are located on the hook surface, the hook surface is close to the top surface of the filter core base 3, and the hard hooks of the hook surface protrude from the top surface of the insertion port, so that the hook surface of the magic tape 7 can better contact the surface of the non-woven mesh cover 8. Because the surface of the non-woven mesh cover 8 has a plurality of fluffs, the hook surface of the magic tape 7 hooks the surface of the non-woven mesh cover 8, thereby improving the connection strength between the filter core base 3 and the non-woven mesh cover 8. The containing groove 6 and the exposed groove 10 are arranged in a circular array on the filter core base 3, and the containing groove 6 and the exposed groove 10 are located between adjacent hook-shaped pieces 5. The arrangement of the containing groove 6 and the exposed groove 10 further improves the contact area and convenience of the contact between the non-woven mesh cover 8 and the hook surface of the magic tape 7, thereby improving the connection strength, stability and uniformity of the structure between the filter core base 3 and the non-woven mesh cover 8.
[0024] The working principle is that when the non-woven mesh cover 8 is sleeved on the dust collector filter core, the elastic rib 801 of the non-woven mesh cover 8 is pulled open, the non-woven mesh cover 8 wraps the filter core top cover 1, the filter core main body 2 and the fixed convex ring 4, the elastic rib 801 is clamped and shrunk to be attached to the bottom of the fixed convex ring 4, and the elastic rib 801 is arranged on the fixed convex ring 4 and reduces the activity space of the non-woven mesh cover 8 through the plurality of hook-shaped pieces 5 on the outer peripheral wall of the fixed convex ring 4. The hook surface of the magic tape 7 on the insertion port hooks the surface structure of the non-woven mesh cover 8 and hooks the non-woven mesh cover 8, thereby further improving the connection strength between the non-woven mesh cover 8 and the filter core base 3, and preventing the non-woven mesh cover 8 from being easily separated.
