[0004] To achieve the above objectives, this utility model provides the following technical solution: a filter element locking mechanism for an insufflator, characterized by a locking base, a sliding ring mounted on the base, and a locking ring rotatably mounted between the locking base and the sliding ring; the locking ring is provided with a locking surface for limiting and locking the filter element; the locking base is also provided with a plurality of positioning and mounting grooves for positioning and mounting the filter element.

[0005] Preferably, the locking ring is also provided with a handle for rotating the locking ring and an opening groove corresponding to the positioning mounting groove on the locking base.

[0006] Preferably, the locking ring is further provided with a limiting step for the sliding ring to limit its movement.

[0007] Preferably, the sliding ring is provided with an annular groove that is adapted to the limiting step and guides the rotation of the locking ring.

[0008] Preferably, the locking base is also equipped with a screw that passes through the sliding ring and connects to the locking ring.

[0009] Preferably, a washer is also fitted onto the screw; a spring is installed between the washer and the locking base.

[0010] The beneficial effects of this utility model are as follows: by using the positioning and mounting groove on the locking base to quickly position the filter element, and then rotating the locking ring to lock the filter element between the locking base and the locking ring, the convenience of locking the filter element is improved.

[0017] The following description, in conjunction with the accompanying drawings, further illustrates the filter element locking mechanism for an insufflator according to this utility model.

[0018] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0019] Referring to Figures 1-5, this embodiment provides a filter element locking mechanism for an insufflator, characterized by a locking base 1, a sliding ring 2 mounted on the base, and a locking ring 3 rotatably mounted between the locking base 1 and the sliding ring 2. The locking ring 3 has a locking surface 301 for limiting and locking the filter element. The locking base 1 also has several positioning mounting slots 101 for positioning and installing the filter element. By utilizing the positioning mounting slots 101 on the locking base 1 to quickly position the filter element, and then rotating the locking ring 3 to lock the filter element between the locking base 1 and the locking ring 3, the convenience of locking the filter element is improved. By rotating the locking ring 3, the locking surface 301 on the rotating locking ring 3 comes into contact with the filter element, locking the filter element between the locking base 1 and the locking ring 3, thereby improving the convenience of locking the filter element.

[0020] Referring to Figures 1-3, the locking ring 3 is also provided with a handle 302 for rotating the locking ring 3 and an opening groove 303 corresponding to the positioning mounting groove 101 on the locking base 1. By pushing the handle 302, the handle 302 drives the locking ring 3 to rotate. When the opening groove 303 on the locking ring 3 is aligned with the positioning mounting groove 101 on the locking base 1, the filter element can be positioned and installed on the locking base 1 along the opening groove 303 and the positioning mounting groove 101. Then, by continuing to push the handle 302, when the opening groove 303 on the locking ring 3 is misaligned with the positioning mounting groove 101 on the locking base 1, the locking ring 3 locks the filter element, thereby facilitating the installation and locking of the filter element.

[0021] Referring to Figures 2-4, the locking ring 3 is further provided with a limiting step 304 for limiting the sliding ring 2; the sliding ring 2 is provided with an annular groove 201 that is adapted to the limiting step 304 and guides the rotation of the locking ring 3; by installing the limiting step 304 on the locking ring 3 into the annular groove 201 on the sliding ring 2, the limiting step 304 on the locking ring 3 is axially limited by the annular groove 201, so that the locking ring 3 can be rotated and installed between the locking base 1 and the locking ring 3 along the annular groove, thereby facilitating the installation of the locking ring 3.

[0022] Referring to Figure 1, a screw 102 is also installed on the locking base 1, which passes through the sliding ring 2 and connects to the locking ring 3; a washer 103 is also fitted on the screw 102; a spring 104 is installed between the washer 103 and the locking base 1; by passing one end of the screw 102 through the locking base 1 and the sliding ring 2 and connecting to the locking ring 3, and fixing the spring 104 between the washer 103 and the locking base 1, the locking base 1, the sliding ring 2 and the locking ring 3 are fixed together.

[0023] In the process of using this utility model, firstly, push the handle 302 to rotate, and the handle 302 will drive the locking ring 3 to rotate, so that the opening groove 303 on the locking ring 3 is aligned with the positioning mounting groove 101 on the locking base 1. Then, align the positioning boss on the filter element with the opening groove 303 on the locking ring 3, and install it into the positioning mounting groove 101 on the locking base 1 along the opening groove 303. Then, continue to push the handle 302 to rotate, and the handle 302 will drive the locking ring 3 to rotate, so that the opening groove 303 on the locking ring 3 is misaligned with the positioning mounting groove 101 on the locking base 1, so that the locking surface 301 on the locking ring 3 contacts the filter element, thereby limiting and locking the filter element between the locking base 1 and the locking ring 3.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
