[0049] When installing, filter cartridge 3 is inserted into the inner chamber of barrel 1 from the opening at the upper end of barrel 1, connecting ring 31 and step surface 11 are connected and fixed, so that the lower end surface of connecting ring 31 and step surface 11 are close (at this time, spring is in compression state), further, sealing cover 2 is installed at the opening of barrel 1.

[0050] When disassembling, the sealing cover 2 is removed from the cylinder body 1, the connecting structure of the connecting ring 31 and the stepped surface 11 is loosened, so that the connecting ring 31 is separated from the stepped surface 11, at this time, the elastic pushing structure 4 acts on the filter cartridge 3, pushes the filter cartridge 3 to move upward, so that the connecting ring 31 is separated from the stepped surface 11, and the operator can take out the filter cartridge 3 from the cylinder body 1 by using a tool or holding the connecting ring 31 by hand.

[0051] It should be noted that the spring in the embodiment can also be replaced by a spring sheet.

[0052] As a preferred scheme, referring to Figure 3 The limiting structure 5 is also provided, and the coaxiality of the filter cartridge 3 and the inner cavity of the cylinder body 1 is ensured through the limiting structure 5. The reason for arranging the limiting structure 5 is that the flow of the medium will impact the cylinder body of the filter cartridge 3 during use, and the impact force may cause the deformation of the filter cartridge 3. After the deformation of the filter cartridge 3, the problems of assembly and disassembly (the deformed filter cartridge 3 is difficult to take out from the cylinder body 1), sealing (the impact force acts on the connecting structure of the connecting ring 31 and the stepped surface 11, so that the sealing of the connecting ring 31 and the stepped surface 11 is invalid), and filtering effect (the deformation of the filter cartridge 3 causes the change of the pore of the filter screen) are caused.

[0053] In the utility model, the limiting structure 5 adopts the first limiting piece 51 and the second limiting piece 52 that cooperate with each other, wherein the first limiting piece 51 is arranged on the bottom surface of the cylinder body 1, and the second limiting piece 52 is arranged on the filter cartridge 3. Specifically, the first limiting piece 51 and the second limiting piece 52 can adopt a pair of arranged bolts and bolt holes (not shown in the figure), and when the first limiting piece 51 and the second limiting piece 52 adopt the mutually cooperating bolts and bolt holes, the number of the first limiting piece 51 and the second limiting piece 52 is multiple pairs.

[0054] It should be noted that the limiting structure 5 can also be realized by other schemes, for example, a plurality of fins are arranged in the inner cavity of the cylinder body 1 at intervals, and the fins are used to push against the outer wall of the filter cartridge 3, so that the limiting is realized.

[0055] As a further preferred scheme, the first limiting piece 51 is arranged in a ring structure, and the position of the spring is limited in the inside of the first limiting piece 51 through the ring structure.

[0056] Referring to Figure 3 , Figure 5The person skilled in the art can understand that when the number of the first limiting member 51 is one, the first limiting member 51 can be an annular plate member opened on the bottom surface of the inner cavity of the cylinder body 1, the spring is clamped inside the first limiting member 51, and the outside of the first limiting member 51 cooperates with the second limiting member 52 to realize the limiting of the filter cartridge 3; at this time, the number of the second limiting member 52 can be one or more, and when the number of the second limiting member 52 is one, the second limiting member 52 can be a hole arranged at the bottom of the filter cartridge 3 or an annular plate member arranged at the bottom of the filter cartridge 3; when the number of the second limiting member 52 is more, the second limiting member 52 can be an arc-shaped plate member (the inner wall of the arc-shaped plate member cooperates with the outer wall of the first limiting member 51 to realize the limiting of the filter cartridge 3), or can be a plurality of columnar structures (the outer wall of the plurality of columnar structures cooperates with the outer wall of the first limiting member 51 to realize the limiting of the filter cartridge 3).

[0057] Embodiment 3

[0058] Reference Figure 6 A different elastic pushing structure 4 is provided.

[0059] The elastic pushing structure 4 in the embodiment has a mounting seat 41 fixedly arranged on the bottom surface of the inner cavity of the cylinder body 1; the mounting seat 41 is rotationally connected with a mounting plate 42, the mounting plate 42 has a contact portion 421, the contact portion 421 can contact the sealing end of the bottom of the filter cartridge 3; at least one elastic member 43 is further arranged, one end of the elastic member 43 acts on the mounting plate 42, and the other end of the elastic member 43 acts on the inner wall of the mounting seat 41 or the cylinder body 1; when the filter cartridge 3 is mounted, the distance between the connecting ring 31 and the step face 11 gradually decreases, so that the elastic member 43 is continuously compressed; when the filter cartridge 3 is dismounted, after the connecting structure between the connecting ring 31 and the step face 11 is disconnected, the elastic member 43 acts on the mounting plate 42, and the mounting plate 42 is rotated around the rotation center (the rotation center is the hinge between the mounting plate 42 and the mounting seat 41) to push the filter cartridge 3 upward, so that the filter cartridge 3 moves upward to drive the connecting ring 31 to move away from the step face 11, and the operator can more conveniently take out the filter cartridge 3.

[0060] As a preferred scheme, the mounting plate 42 further has a limiting portion 422, the limiting portion 422 and the contact portion 421 form a V-shaped or C-shaped structure; when the filter cartridge 3 is mounted, the connecting ring 31 approaches the step face 11, which can drive the mounting plate 42 to rotate (the rotation center is the hinge between the mounting plate 42 and the mounting seat 41), so that the limiting portion 422 moves to the outer side wall of the filter cartridge 3. When the connecting ring 31 is tightly attached to the step face 11, the limiting portion 422 is in contact with the outer side wall of the filter cartridge 3.

[0061] When the filter cartridge 42 and the limiting portion 422 are in linear contact in the circumferential direction, two or more sets of the elastic pushing structure 4 need to be arranged (the multiple sets of the elastic pushing structure 4 are arranged along the same circumferential direction at intervals) to limit the filter cartridge 3 and ensure the coaxiality of the filter cartridge 3 and the inner cavity of the cartridge body 1.

[0062] When the filter cartridge 42 and the limiting portion 422 are in point contact in the circumferential direction, three or more sets of the elastic pushing structure 4 need to be arranged (the multiple sets of the elastic pushing structure 4 are arranged along the same circumferential direction at intervals) to limit the filter cartridge 3 and ensure the coaxiality of the filter cartridge 3 and the inner cavity of the cartridge body 1.

[0063] It should be noted that only the high-low connection pipe basket filter is shown in the drawings, but those skilled in the art can understand that the utility model can also be used for straight-through basket filters.

[0064] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and deformations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
