Description

Technical Field

[0001] This utility model relates to the field of filter element structure technology, and in particular to a high-flux household membrane module. Background Technology

[0002] As a core component commonly used in the water treatment field, the structure of household membrane modules directly affects the filtration effect. The module mainly consists of an outer cylinder, filter element, outlet pipe, and lid. The assembly relationship of each component is as follows: the filter element is inserted into the outer cylinder, and the outlet pipe is further inserted into the filter element. After the filter element and outlet pipe are assembled in the outer cylinder, the lid structure is used to seal the end face of the outer cylinder to ensure the sealing and stability of the module during the water treatment process. In existing technologies, the connection between the lid structure and the outer cylinder structure is mostly achieved through threaded connection. Specifically, an internal thread is machined on the inner surface of the lid, and an external thread matching the internal thread is machined on the inner surface of the outer cylinder. By screwing the lid onto the outer cylinder, the engagement of the threads achieves a fixed connection between the two. This threaded connection method has been widely used in the industry due to its simple structure, low processing difficulty, and relatively low cost. However, this connection method has a significant drawback: in the final stage of tightening the lid and outer cylinder, the axial and circumferential forces generated by the thread engagement are transmitted to the filter element inside the outer cylinder, creating a spinning effect. This spinning effect causes the filter element to undergo a certain degree of torsion deformation. This torsion disrupts the originally regular filtration channels and structure inside the filter element, thereby affecting the distribution of the filter media and the water flow path, ultimately reducing the filtration efficiency and quality of household membrane modules, making it difficult to meet users' requirements for water treatment performance.

[0016] In a preferred embodiment of this utility model, the side wall of the bucket lid 2 is provided with a through-hole convex clip 204 for the outer cylinder convex clip 101 to pass through; the outer cylinder convex clip 101 is inserted into the through-hole convex clip 204 from bottom to top; the positioning ring 5 is engaged between the outer cylinder convex clip 101 and the bucket lid convex clip 203; the positioning ring 5 is used to prevent the outer cylinder convex clip 101 from being pulled downward from the through-hole convex clip 204; the upper and lower end faces of the positioning ring 5 are respectively pressed against the bottom end face of the outer cylinder convex clip 101 and the top end face of the bucket lid convex clip 203. After the outer cylinder protrusion 101 is inserted into the protrusion slot 204, the outer cylinder protrusion 101 passes from below the lid protrusion 203 to above the lid protrusion 203. Then, the positioning ring 5 is used to clamp and fix it between the lid protrusion 203 and the outer cylinder protrusion 101, so that the lid 2 cannot be pulled out from the outer cylinder 1, thus fixing the lid 2 to the outer cylinder 1.
