Further, a sealing ring is provided between the outer circumference of both ends of the switching shaft tube and the inner wall of the communication pipeline, and the sealing ring is provided on the plug and the outer circumference of the water inlet convex pipe.

Further, a first sealing protrusion matching with the left end of the switching shaft tube is provided between the raw water inlet and the purified water output port, and a second sealing protrusion matching with the right end of the switching shaft tube is provided between the purified water output port and the purified water outlet. Seal convex part.

Further, the end of the switching shaft tube is provided with a plug-in interface for plugging and fitting with the plug or the water inlet convex tube.

Further, the lower part of the valve body is screwed to the filter bottle assembly.

Compared with the prior art, the utility model has the following beneficial effects: it is not necessary to close the water supply valve before cleaning or replacing the built-in filter device, and after the shaft tube is moved axially through the operation, the normal water supply is maintained, and no damage is caused to the normal household water use. At the same time, the normal filter water circuit can be disconnected to facilitate the removal of the built-in filter device for cleaning.

Below in conjunction with accompanying drawing and specific embodiment, the utility model is described in further detail.

detailed description

In order to make the above-mentioned features and advantages of the present invention more comprehensible, the following specific examples are given together with the accompanying drawings and described in detail as follows.

As shown in Figures 1 to 3, the uninterrupted water supply structure for removing and replacing the filter element includes a valve body 2, and the two ends of the valve body 2 are respectively provided with a water inlet 4 and a water outlet 5, and the lower part of the valve body 2 is connected to the filter bottle assembly 1. Connection, the valve body 2 is provided with a communication pipeline connecting the water inlet 4 and the water outlet 5, the communication pipeline is provided with a switching shaft tube 6, and the valve body 2 is provided with a handle 3 that drives the switching shaft tube 6 to move axially , the left end of the connecting pipeline is provided with a water inlet baffle 7, and the right end is provided with a water outlet baffle 9, and the water inlet baffle 7 extends to the right with a water inlet convex pipe 8 that can be plugged with the switching shaft tube 6, and the water outlet baffle 9 extends to the left with a plug 10 that can be plugged with the switching shaft tube 3, and the water outlet partition 9 on the outer peripheral side of the plug 10 is provided with a clean water outlet 11 that communicates with the water outlet 5. A raw water inlet 13 and a purified water outlet 12 communicated with the filter bottle assembly 1 are also provided.

In this embodiment, sealing rings are provided between the outer circumference of both ends of the switching shaft tube 6 and the inner wall of the communication pipeline, and sealing rings are provided on the outer circumference of the plug 11 and the water inlet convex pipe 8 .

In this embodiment, between the raw water inlet 13 and the purified water outlet 12, a first sealing protrusion 14 matching the left end of the switching shaft tube 6 is provided, and between the purified water outlet 12 and the purified water outlet 11, a Switch the second sealing protrusion 16 matched with the right end of the shaft tube 6 .
