Filter element butt joint mechanism

Abstract

The invention discloses a filter element butt-joint mechanism which comprises a fixed base, a movable base and a butt-joint mechanism, the butt joint base is arranged in the mounting cavity and is close to the inner end of the fixed base; the filter element comprises a shell, the head of the shell is used for being inserted into the mounting cavity from the outer end, and an insertion pipe is formed at the head of the shell; a limiting slide card mechanism; a screw transmission mechanism; wherein a groove is formed in the head of the shell, and the insertion pipe is formed in the groove; a boss matched with the groove is formed on the butt joint base, and an insertion hole matched with the insertion pipe is formed in the boss; the limiting sliding clamping mechanism comprises a limiting lug formed on the inner wall of the fixed base and a lug groove formed in the shell, and the lug groove extends in the circumferential direction with the groove bottom of the groove as the starting end so as to at least form a main body section located on the same plane. The spiral transmission mechanism comprises a guide groove formed in the inner wall of the fixed base and a sliding part formed on the periphery of the butt-joint base and used for sliding along the guide groove, and at least a spiral section is formed in the guide groove.

Description

technical field [0001] The invention relates to the technical field of water purification, in particular to a filter element docking mechanism. Background technique [0002] The filter element in the prior art usually includes a cylindrical shell and a filter membrane core arranged in the shell; the head of the shell is formed with a plurality of concentric circles of partition rings, and the partition rings define, for example, a raw water inlet, a concentrated water inlet, and a For water outlets such as the water outlet and the clean water outlet, the rear of the casing is integrally formed with a screwing part. A sealing ring is sleeved on the separating ring, and a thread is formed on the head of the casing. [0003] The filter element needs to be installed on the main body of the water purifier. Specifically, a column-shaped installation cavity extending inward is formed on the side of the main machine, and a base is formed at the bottom of the installation cavity, an...

AI Technical Summary

Problems solved by technology

[0004] However, in the above-mentioned process of installing the filter element on the main engine, since the sealing ring produces greater resistance to the base during the insertion of the separating ring into the interface of the base, it is necessary to apply the insertion force while applying the insertion force with one hand. Screwing force, and the other hand of the person is required to hold the host to avoid excessive insertion force and cause the host to move. The operation process is very difficult, and non-professionals sometimes cannot complete the installation
