the arc-shaped sealing gasket 3 is positioned between the cavity wall of the rotary valve cavity 102 and the rotary valve core 2, and a sealing gasket water passing hole 301 is arranged at the position of the arc-shaped sealing gasket 3 corresponding to each water outlet channel;

in this embodiment, the positions of the water outlet holes 203 of the valve cores are reasonably arranged, so that the rotary valve core 2 can have a first water outlet state in which only the first water outlet channel 103 is communicated with the valve core water cavity 202; and has a second water outlet state rotated to communicate only the second water outlet passage 104 with the valve cartridge water chamber 202.

An end face of one end of the valve seat 1 is provided with an annular clamping table 105 surrounding an annular space 1051, and an outlet of the first water outlet channel 103 is positioned outside the annular clamping table 105; the valve seat 1 is further provided with a filtered water outlet hole 106 communicating with the in-ring space 1051.

The spool housing 200 is disposed outside the rotary shift spool assembly 100. The filter 300 is inserted in the inner wall of the annular clamping table 105 of the valve seat 1 in a sealing manner, and a filtering water inlet hole 300a is formed in the end face of the filter 300. Before use, the filter 300 needs to be filled with a filter material such as activated carbon. The filter housing 400 is covered outside the filter 300 and is in threaded sealing connection with one end of the valve core housing 200.

The first water outlet channel 103 of the valve seat 1 is connected to the filtered water outlet 106 of the valve seat 1 after passing through the space between the filter housing 400 and the valve core housing 200, the filtered water inlet 300a, and the inner space 1051 of the valve seat 1 in sequence.

The spring thimble assembly 500 is mounted on the side of the valve seat 1 remote from the filter housing 400. The rotary cover assembly 600 is positioned on one side of the rotary shift valve core assembly 100 away from the filter housing 400 and is in synchronous rotation connection with the rotary valve core 2 of the rotary shift valve core assembly 100; a plurality of positioning grooves 600a which are clamped and positioned with the spring thimble assembly 500 are arranged on one side of the spiral cover assembly 600 close to the spring thimble assembly 500. The rotary cap assembly 600 is rotated until the spring thimble assembly 500 is snapped into different positioning grooves 600a, thereby achieving positioning of different gears.

The water purifier provided in this embodiment, after connecting the water inlet channel 101 to the water outlet of the faucet, is used as follows:

(1) If necessary, the filtered water is used

S10: the rotary cover assembly 600 is screwed until the rotary valve core 2 rotates to a first water outlet state, at which time, only the first water outlet channel 103 is communicated with the valve core water cavity 202;

s20: the switch of the tap is turned on, and water enters the rotary valve cavity 102 through the water inlet channel 101; then, the water enters the valve core water cavity 202 through the valve core water inlet 201; then, the water flows out of the valve seat 1 through the first water outlet passage 103;

s30: after water flows out of the valve seat 1, the water flows to the filtered water outlet hole 106 of the valve seat 1 through the interval space between the filter housing 400 and the valve core housing 200, the filter water inlet hole 300a and the inner ring space 1051 of the valve seat 1 in sequence, and then flows downwards through the filtered water outlet hole 106;

at this time, the water received under the filtered water outlet hole 106 is filtered water.

(2) If it is desired to use unfiltered water

S10: the rotary cover assembly 600 is screwed until the rotary valve core 2 rotates to a second water outlet state, at which time, only the second water outlet channel 104 is communicated with the valve core water cavity 202;

s20: the switch of the tap is turned on, and water enters the rotary valve cavity 102 through the water inlet channel 101; then, the water enters the valve core water cavity 202 through the valve core water inlet 201; then, the water flows out of the valve seat 1 through the second water outlet passage 104;

at this time, the water received under the second water outlet passage 104 is unfiltered water.

In this embodiment, a limiting slot 109 is provided in the rotary valve cavity 102, and the arc-shaped sealing gasket 3 is inserted into the limiting slot 109 to limit the relative rotation between the arc-shaped sealing gasket 3 and the valve seat 1.

Further, each of the gasket water holes 301 is provided with a ring of waterproof bosses 302 protruding toward the rotary valve core 2 in a surrounding manner, so as to prevent water from flowing into each water outlet channel through the gap between the rotary valve core 2 and the arc gasket 3 (mainly to ensure that water entering each water outlet channel must come from the valve core water cavity 202).

In this embodiment, the valve core water inlet 201 is located at the end face of the rotary valve core 2 near the bottom of the rotary valve cavity 102, so that in order to avoid the blocking of the valve core water inlet 201 caused by the fitting of the orifice of the valve core water inlet 201 and the bottom of the rotary valve cavity 102, a limit boss 108 is disposed at the bottom of the rotary valve cavity 102, and when the rotary valve core 2 abuts against the limit boss 108, a gap is left between the rotary valve core 2 and the bottom of the rotary valve cavity 102, so that water flows into the valve core water cavity 202 from the rotary valve cavity 102.

It will be appreciated that the position of the spool outlet port 203 may be designed so that the rotary spool 2 may communicate with either the first outlet passage 103 or the second outlet passage 104 alone.

For example, each water outlet channel is correspondingly provided with one valve core water outlet hole 203, and different valve core water outlet holes 203 are positioned on different bus bars of the rotary valve core 2. Therefore, each time one of the valve cartridge outlet holes 203 is aligned with one of the outlet channels, the other valve cartridge outlet holes 203 are deviated from the corresponding outlet channel and are blocked by the arc-shaped packing 3, so that the circulation is impossible.

Of course, two valve core water outlet holes 203 may be correspondingly disposed in each water outlet channel; different spool water outlets 203 are located on different buses, and a connecting line between two spool water outlets 203 corresponding to the same water outlet channel passes through the axis of the rotary spool 2. This arrangement allows two positions for the outflow of filtered or unfiltered water for each revolution of the rotary spool 2.

In this embodiment, the number of the second water outlet passages 104 is two; an annular water outlet groove 107 is arranged around the outer part of one second water outlet channel 104, and the other second water outlet channel 104 is communicated with the annular water outlet groove 107. The user can rotate to different gears to realize straight water column water outlet or annular water outlet.

It can be understood that the amount of water in the second water outlet channel 104 can be one, three or more, so long as the positions of the valve core water outlet holes 203 are reasonably set, only one valve core water outlet hole 203 of the rotary valve core 2 can be communicated with the corresponding water outlet channel at the same time, and no water is discharged from the other water outlet channels.

In summary, the rotary shift valve core assembly 100 and the water purifier provided in the present embodiment have the following advantages:

(1) the rotary valve core 2 is rotated, so that the rotary valve core 2 can be switched between a first water outlet state and a second initial state, and further the functions of only flowing out filtered water and only flowing out unfiltered water are realized, and the service life of the filter core is prolonged;

(2) has a plurality of water outlet gears for selection so as to meet diversified use requirements of users.

It should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is for clarity only, and that the skilled artisan should recognize that the embodiments may be combined as appropriate to form other embodiments that will be understood by those skilled in the art.

The above list of detailed descriptions is only specific to practical embodiments of the present utility model, and they are not intended to limit the scope of the present utility model, and all equivalent embodiments or modifications that do not depart from the spirit of the present utility model should be included in the scope of the present utility model.
