and a reset means provided between the push buttons 30 and the drive ring 20 for driving the push buttons 30 to reset.

The driving ring 20 which can drive the core bar 14 to rotate is sleeved on the core bar 14 of the valve core 10, the bottom of the key 30 is provided with an accommodating groove 31 which can accommodate the driving ring 20, the outer wall of the driving ring 20 or the inner wall of the accommodating groove 31 is provided with a first guide inclined surface, the inner wall of the accommodating groove 31 or the outer wall of the driving ring 20 is provided with a first guide block which is matched with the first guide inclined surface, then the driving ring 20 and the key 30 are fixed on the upper part of the valve core 10 through an upper cover 40, the key 30 can extend out of the upper surface of the upper cover 40 and can move up and down relative to the upper cover 40, and a reset device which is used for driving the key. In the using process, when a user needs to switch the waterway, the user presses the key 30, at this time, due to the friction force of the hand on the key 30, the key 30 cannot rotate, and the key 30 and the driving ring 20 generate opposite movement, due to the action of the first guiding inclined plane and the first guiding block, under the condition that the key 30 does not rotate, the opposite movement of the key 30 and the driving ring 20 drives the driving ring 20 to rotate, so as to drive the core rod 14 to rotate to switch the waterway. After the user loosens the hand, make button 30 resume to the state of not pressing through resetting means, and then accomplish a water route and switch, press button 30 once, can carry out continuous switching to the water route, when 11 quantity of apopore are different, the angle that core bar 14 drove the rotation of movable plate 13 is also different, and the angle that drive ring 20 drove the rotation of core bar 14 mainly confirms according to the parameter of first direction inclined plane and first guide block, this parameter in use specifically formulate can, in this scheme, preferred outlet hole quantity is 3. Through this scheme, the diverter valve switches from traditional handle to the switching of push type, and is more safe to the user, is difficult for taking place the touching. And the pressing is more ergonomic relative to the rotation through the handle, and the problems of slipping and the like can be avoided.

In the above scheme, the driving ring 20 may be directly sleeved on the core bar 14 to directly drive the core bar 14 to rotate, in this way, when the key 30 is reset, since the key 30 loses the force limitation of the hand, no limitation is generated in the rotation direction, and the core bar 14 is limited to rotate by the action of the water pressure and the friction force of the movable plate 13, so that the core bar 14 limits the driving ring 20 to not rotate at this time, and the key 30 rotates and resets when the key 30 is reset. However, in this case, a certain force is always applied to the core rod 14, so that the drive ring 20 preferably indirectly rotates the core rod 14. In this embodiment, the core bar 14 is preferably square, and of course, the core bar may have other irregular shapes, a follower plate 50 is further disposed below the driving ring 20, a mounting hole 51 having the same shape as the core bar 14 is disposed on the follower plate 50, the follower plate 50 is sleeved on the core bar 14 through the mounting hole 51, at this time, the follower plate 50 can directly drive the core bar 14 to rotate when rotating, a wedge-shaped limit table 52 is disposed at the top of the follower plate 50, a butting table 23 matched with the wedge-shaped limit table 52 is disposed at the bottom of the driving ring 20, and the driving ring 20 can drive the follower plate 50 to rotate through the wedge-shaped limit table 52 and the butting table 23. In this way, although the driving ring 20 is sleeved on the core bar 14, the driving ring 20 will not contact the core bar 14 when rotating, the driving ring 20 is pressed on the follower sheet 50, the abutting table 23 abuts on the wedge-shaped limit table 52, when the user presses the key 30, the key 30 and the driving ring 20 move in opposite directions, due to the action of the first guiding inclined plane and the first guiding block, under the condition that the key 30 does not rotate, the key 30 and the driving ring 20 move in opposite directions to drive the driving ring 20 to rotate, and at this time, the abutting table 23 abuts on the side limited by the wedge-shaped limit table 52 to drive the follower sheet 50 to rotate and further drive the core bar 14 to rotate, and when the user releases the hand, the key 30 is reset to the non-pressed state under the action of the reset device, at this time, even if the key 30 does not rotate, the driving ring 20 rotates in the direction along the inclined plane of the wedge-shaped limit table 52, therefore, the force is not brought to the follow-up piece 50 to drive the follow-up piece 50 to rotate, and the using effect is better.

In the above-mentioned embodiment, the follower 50 may be connected to the core rod 14 by a fastener.

Further, if the follower 50 is directly disposed on the core rod 14, since the bottom surface of the follower 50 is in direct contact with the surface of the valve core 10, when the push button 30 is pressed to drive the follower 50 to rotate, the friction force between the follower 50 and the surface of the valve core 10 needs to be overcome, which makes the force required by the user to use large, and therefore, it is preferable to further dispose a bearing 60 between the follower 50 and the valve core 10. The bearing 60 prevents the follower 50 from directly contacting the valve element 10, and the friction between the inner and outer rings of the bearing 60 is very small, so that the follower 50 does not need to overcome much friction when rotating.

Further improvement is made, in order to make the present solution drive the driving ring 20 to drive the core bar 14 to rotate best through the case, at this time, it is necessary to limit the axial movement of the limiting rod 80, for this reason, it is preferable to further include the limiting rod 80, the limiting rod 80 penetrates through the driving ring 20 from the top of the driving ring 20 to be fixedly connected with the top of the core bar 14, a blocking portion is disposed at a portion of the limiting rod 80 above the driving ring 20, and the blocking portion can limit the moving distance of the driving ring 20 relative to the core bar 14.

In the above solution, the return means is preferably a spring 70, one end of the spring 70 abuts against the bottom of the receiving groove 31, and the other end of the spring 70 abuts against the top of the limiting rod 80. The spring 70 may preferably be elastic rubber, and the elastic rubber drives the key 30 to return by its own elasticity.

Further, the improvement is that the scheme that the driving ring 20 is indirectly sleeved on the core rod 14 is adopted, when the key 30 is reset, the rotation angle can be shared by the rotation of the key 30 and the rotation of the driving ring 20, and when the key 30 is reset, the rotation angle of each time is not necessary, and in many cases, people hope to directly see which waterway is switched to which waterway on the key 30, therefore, preferably, at least one elastic driving foot 91 is further arranged outside the key 30, a convex block 92 is arranged outside the elastic driving foot 91, and the convex block 92 can move back and forth relative to the outer surface of the key 30 along with the elastic driving foot 91 under the action of external force;
