The disassembly and assembly of the valve core mechanism is simple and fast, and users can disassemble and operate it without changing the entire faucet, thereby reducing maintenance costs.

[0021] By means of the adaptive expansion design of the first adaptive expansion group in the middle of the inner ring of the first sealing ring and the second adaptive expansion group in the middle of the inner ring of the second sealing ring, the outer rings of the first sealing ring and the second sealing ring can always be flexibly pressed against the groove wall of the movable groove of the valve core assembly, and the sealing performance of the first sealing ring and the second sealing ring will not be reduced due to wear caused by the left and right sliding of the first sealing ring and the second sealing ring in the movable groove of the valve core assembly over a long period of time, thereby improving the service life of the first sealing ring and the second sealing ring.

[0022] Through the positioning and fitting design of the first positioning slide column and the second positioning slide groove, and the offset movement design of the two gear adjustment seats and the two moving pulleys, the opening and closing of the valve core assembly in the movable groove of the valve core assembly is achieved by sliding left and right, without the need to rotate the valve core assembly. This avoids the offset wear between the valve core assembly and the first spring, and prevents the valve core assembly from shifting in the closed position of the valve core assembly in the movable groove of the valve core assembly, resulting in the problem of inability to completely block water.

The first quick-release slot 12 has the same structure as the second quick-release slot 13.

[0042] Working principle:

[0043] The assembly method is as follows: first, the first adaptive expansion group 212, the second adaptive expansion group 213, the first sealing ring 214, and the second sealing ring 215 are assembled on the valve core body 211 in advance to form the valve core assembly 21, and then the valve core assembly 21 is inserted into the valve core assembly movable groove 14 from right to left, and pushed to the innermost left, and then the first spring 23 is inserted into the second spring clamping groove 226, and the first quick-install cover group 22 and the first spring 23 are clamped in the first quick-install groove 12 from left to right. At this time, the other end of the first spring 23 will be in the first spring clamping groove 211. 3, and the first positioning slide post 2114 will be aligned and passed into the second positioning slide groove 227, and the first quick-install cover assembly 22 will be twisted to make the first anti-dropout sleeve hole 224 and the telescopic clamping member 122 snap-fit ​​and fixed, and then the second quick-install cover assembly 24 will be snap-fitted into the second quick-install groove 13 from right to left, and the second quick-install cover assembly 24 will be twisted to make the second anti-dropout sleeve hole 244 and the telescopic clamping member 122 in the second quick-install groove 13 snap-fit ​​and fixed, at this time, the two moving pulleys 248 will automatically align and abut against the surfaces of the two shifting blocks 2161, completing the rapid assembly of the valve core mechanism 2 in the faucet assembly 1 cavity.

[0044] The removal method is to use an external needle tool to pass through the second anti-detachment hole 244 to press down the telescopic clamp 122, so that the telescopic clamp 122 is disengaged from the second anti-detachment hole 244, and the second quick-release cover group 24 is twisted synchronously, so that the second quick-release cover group 24 and the switch handle 25 can be taken out to the right in the second quick-release groove 13, and then a screwdriver is used from left to right through the removal opening 228 to push the first positioning slide column 2114, so that the valve core assembly 21 can slide to the right out of the valve core assembly active groove 14, so that the valve core assembly 21 can be taken out for cleaning or replacement of the first sealing ring 214 and the second sealing ring 215, and the dirt in the valve core assembly active groove 14 cavity can be cleaned, and the first quick-release cover group 22 does not need to be removed for cleaning.

[0045] The method of use is to rotate the switch handle 25, through the bearing 245, the spline 246, and the swing frame 247, so that the two moving pulleys 248 move from a low position to a high position between the various gear surfaces 2162 and the walking slope 2163 on the gear adjustment block 2161, which will push the valve core assembly 21 to move left in the valve core assembly movable groove 14, so that the first sealing ring 214 can seal the water inlet hole 16 and the water outlet hole 17 to open a gap to the left, and water can enter from the water inlet hole 16 and flow into the water outlet hole 17 through the arc-shaped water inlet groove 2115.

[0046] It should be noted that the size of the gap opened by the first sealing ring 214 for the water inlet hole 16 and the water outlet hole 17 is achieved by controlling which gear surface 2162 the two moving pulleys 248 move on, and the second sealing ring 215 acts to seal the right side of the arc-shaped water inlet groove 2115.

[0047] It should also be noted that when the first sealing ring 214 and the second sealing ring 215 are worn out due to long-term use, the first adaptive expansion group 212 and the second adaptive expansion group 213 will expand outwards and adaptively press the middle of the inner rings of the first sealing ring 214 and the second sealing ring 215, so that the middle of the outer rings of the first sealing ring 214 and the second sealing ring 215 are adaptively deformed and softly sealed to press against the circumference of the groove wall of the active groove 14 of the valve core component, so that the first sealing ring 214 and the second sealing ring 215 will not have a slight wear and tear and the sealing performance will decline. The problem of reducing the service life of the first sealing ring 214 and the second sealing ring 215 is increased. When the first sealing ring 214 and the second sealing ring 215 are deformed outward in the middle, under the reinforcing sealing effect of the two reinforcing sealing arc grooves 21113 and the two reinforcing sealing arc convex edges 2141, the inner circles of the first sealing ring 214 and the second sealing ring 215 can still be tightly attached to the bottom of the first sealing ring groove 2111 and the second sealing ring groove 2112, and the two sides will not be lifted up due to the deformation in the middle to cause gap water seepage.
