DETAILED DESCRIPTION

[0014] The following is a specific embodiment of the present application and further describes the technical scheme of the present application in combination with the drawings, but the present application is not limited to these embodiments.

[0015] As shown in Figure 1 , Figure 2 , Figure 3 , the air pump of the detachable filter comprises an air pump main body 1, an air inlet pipe 2 located on the air pump main body 1, and a filter 3 mounted on the air inlet pipe 2. The air inlet pipe 2 is provided with a sealing ring 4 for increasing the sealing performance at the pipe opening. A plurality of mounting seats 5 are arranged in a ring shape along the inner wall of the air inlet pipe 2. A connecting rod 6 is integrally formed with the mounting seat 5 below the mounting seat 5. A matching part 7 is slidably arranged on one end of the connecting rod 6. The connecting rod 6 extends into the matching part 7, and a limiting part 8 is arranged inside the matching part 7 to limit and abut against the matching part 7.

[0016] One end of the filter 3 is provided with a mounting part 9 for mounting with the air inlet pipe 2. A plurality of matching grooves 10 corresponding to the positions of the matching part 7 are formed in the mounting part 9. An arc-shaped groove 11 is arranged at one end of the matching groove 10 for abutting against the matching part 7. A sliding surface 12 is arranged at the other end of the matching groove 10 and inclined upward from the groove bottom.

[0017] A spring leaf 14 with elastic return function is arranged between the matching groove 10 and the arc-shaped groove 11. The spring leaf 14 is arc-shaped on both sides for limiting the matching part 7 together with the arc-shaped groove 11. An auxiliary elastic sheet 15 is arranged between the spring leaf 14 and the arc-shaped groove 11 for supporting and connecting. The auxiliary elastic sheet 15 is symmetrically arranged on both sides of the spring leaf 14.

[0018] In the installation, the installation part 9 passes through and presses the sealing ring 4 until entering the air inlet pipe 2, meanwhile the installation part 9 pushes the edge of the matching part 7 to the inner wall of the air inlet pipe 2, continue to push the filter 3 until the matching part 7 is on the installation part 9, at this time, rotate the filter 3 to make the matching part 7 enter the matching groove 10, rotate the filter 3 again to make the matching part 7 extrude the spring leaf 14 to enter the arc-shaped groove 11, the installation is completed.

[0019] In the disassembly, rotate the filter 3 to make the matching part 7 disengage from the arc-shaped groove 11, continue to rotate to make the matching part 7 pass through the sliding surface 12 and move upward, at the same time, pull the filter 3 outward in the process of rotating until the filter 3 disengages from the air inlet pipe 2.

[0020] Further, the sealing ring 4 and the edge of the installation part 9 are both provided with chamfers for facilitating the cooperation, which facilitates the cooperation and prevents the edge of the installation part 9 from damaging the sealing ring 4.

[0021] Further, the connecting rod 6 is provided with the elastic element 13 with the elastic reset function, and the bottom end of the matching part 7 is spherical arc.

[0022] The specific embodiments described in the present document are only illustrative of the spirit of the present application. Those skilled in the art to which the present application belongs can make various modifications or supplements to the described specific embodiments or use similar ways to replace, but will not deviate from the spirit of the present application or exceed the scope defined by the appended claims.

[0023] Although the terms such as air pump body 1, air inlet pipe 2, filter 3, sealing ring 4, mounting seat 5, connecting rod 6, matching part 7, limiting part 8, installation part 9, matching groove 10, arc-shaped groove 11, sliding surface 12, elastic element 13, spring leaf 14, auxiliary elastic sheet 15 are used more in the present document, but the possibility of using other terms is not excluded.
