[0021] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0022] Example

[0023] like Figure 1 , Figure 2 As shown, Figure 1 The diagram shown is a front view of the quick-release membrane housing in the embodiment. Figure 2 The diagram shown is a front view of the membrane shell and membrane cover in the embodiment;

[0024] This device includes:

[0025] The membrane housing 10 and the membrane cover 20 are provided. The membrane cover 20 covers the open end of the membrane housing 10. The ends of the membrane housing 10 and the membrane cover 20 that are close to each other are provided with protrusions.

[0026] Connector 30, connector 30 locks the membrane housing 10 and membrane cover 20.

[0027] The connector 30 locks the membrane housing 10 and the membrane cover 20 together. By disassembling the connector 30, the membrane housing 10 and the membrane cover 20 can be quickly separated, thereby allowing for quick installation or replacement of the filter element inside the membrane housing 10.

[0028] like Figure 3 , Figure 4 , Figure 5 As shown, Figure 3 The diagram shown is a top view of the quick-release membrane housing in the embodiment; Figure 4 What is shown is Figure 1 Enlarged schematic diagram of the structure at point A in the diagram; Figure 5 The diagram shown is a top view of the connector (in its disassembled state).

[0029] The connector 30 includes: a semi-ring hoop 31 and a semi-ring hoop 32 that are hinged to each other. Both the semi-ring hoop 31 and the semi-ring hoop 32 have annular grooves 33 on their inner sides. The ends of the semi-ring hoop 31 and the semi-ring hoop 32 away from the hinge end are provided with opening and closing components.

[0030] The first half-ring hoop 31 and the second half-ring hoop 32 form a complete ring structure. The first half-ring hoop 31 and the second half-ring hoop 32 are hinged together, so that the connector 30 can open and close like a clamp.

[0031] The annular groove 33 corresponds to the protrusions on the membrane housing 10 and the membrane cover 20. When the connector 30 is closed, the protrusions on the membrane housing 10 and the membrane cover 20 are embedded in the annular groove 33, which serves as a positioning and connection function.

[0032] The opening and closing assembly is used to control the opening and closing of the connector 30.

[0033] like Figure 3 , Figure 4 , Figure 5 As shown, Figure 3 The diagram shown is a top view of the quick-release membrane housing in the embodiment; Figure 4 What is shown is Figure 1 Enlarged schematic diagram of the structure at point A in the diagram; Figure 5 The diagram shown is a top view of the connector (in its disassembled state).

[0034] The opening and closing assembly includes an extension frame 34. A locking block 35 is rotatably provided inside the extension frame 34 of the semi-ring hoop 1 31. An insert block 36 is elastically provided at the top of the end of the locking block 35 away from the rotating end. An insertion hole 37 is provided on the extension frame 34 of the semi-ring hoop 2 32 to engage with the insert block 36.

[0035] In the locked state: the end of the locking block 35 away from the rotating end enters the inner side of the extension frame 34 of the semi-ring 32 and the insert block 36 is embedded in the insertion hole 37.

[0036] The extension frame 34 serves as a support and guide structure, providing installation space and movement path for the locking block 35 and the insertion block 36. The locking block 35 is installed inside the extension frame 34 of the semi-ring hoop 31 and can rotate around the axis.

[0037] When the first half-ring clamp 31 and the second half-ring clamp 32 are in the closed state, the locking block 35 can be rotated, and an external force can be applied to the insertion block 36 at the same time, so that the insertion block 36 does not affect the locking block 35 from entering the inner side of the extension frame 34 of the second half-ring clamp 32. When the locking block 35 enters the inner side of the extension frame 34 of the second half-ring clamp 32, after the external force applied to the insertion block 36 is removed, the elastic insertion block 36 will reset and automatically embed into the insertion hole 37, completing the final locking action.

[0038] like Figure 6 As shown, Figure 6 The diagram shown illustrates the structure of the insertion block and the locking block working together.

[0039] The top of the card block 35 is provided with an installation groove 351, and the insert block 36 is movably embedded in the installation groove 351 along the longitudinal direction. A spring 352 is also provided in the installation groove 351, and the two ends of the spring 352 are fixedly connected to the bottom wall of the installation groove 351 and the insert block 36, respectively.

[0040] In its natural state, a portion of the insert 36 is pushed out of the mounting slot 351 by the spring 352.

[0041] The mounting groove 351 is a longitudinally extending groove used to accommodate the insert 36 and the spring 352 that serves as a reset mechanism. The insert 36 can slide longitudinally within the mounting groove 351 and has a certain free travel. The top of the insert 36 has an arc-shaped structure. When the insert 36 is pressed by external force, it can enter the mounting groove 351. After the external force is removed, a part of it is exposed and extends out of the mounting groove 351 in its natural state so as to be inserted and mated with the socket 37.

[0042] Working principle: During installation, place the membrane cover 20 at the open end of the membrane housing 10, ensuring that the protrusions of both are aligned. Then close the connector 30: the semi-ring 31 and semi-ring 32 wrap around the protrusions of the membrane housing 10 and the membrane cover 20 through their inner annular grooves 33. Then rotate the locking block 35 while applying external force to the insert block 36, so that the insert block 36 does not affect the insertion of the locking block 35 into the extension frame 34 of the semi-ring 32. When the locking block 35 enters the extension frame 34 of the semi-ring 32, remove the external force applied to the insert block 36. The elastic insert block 36 will reset and automatically embed into the insertion hole 37, completing the final locking action. When the filter element needs to be replaced, the operator needs to press down on the insert block 36 to disengage it from the insertion hole 37, and then push the locking block 35 outward to open the semi-ring 31 and semi-ring 32, so that the membrane cover 20 can be easily removed for filter element replacement or maintenance.

[0043] This embodiment also provides a filter, including the quick-release membrane housing described above.

[0044] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
