[0002] The current push valve core switch adopts a ballpoint pen ratchet structure. The general ballpoint pen ratchet structure includes a push rod, a movable ratchet and a fixed ratchet; the push rod moves up and down along the axis, and the movable ratchet needs to move up and down along the axis and rotate around the axis; the fixed ratchet is generally set on the shell to provide a high and low position limit for the movable ratchet; the working spring is against the movable ratchet, and the push rod is separated from the movable ratchet, so that the push rod is in a suspended state with a certain amount of shaking.

[0003] The current push-to-switch valve core and the pilot valve are usually opened only by water pressure. When the water pressure is low, the pilot valve cup is not easy to open and the flow rate is small. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides a push switch, comprising: a push operating member, a low-position positioning member;

[0006] The pressing operating member moves between a high position or a low position along the axial direction; the pressing operating member includes a rotation reversing member for cooperating with the low-position positioning member, and a limiting member for locking with the low-position positioning member;

[0007] The low-position positioning member includes a reversing matching member and a limiting matching member arranged up and down along the axial direction, and a clearance channel arranged through the axial direction;

[0008] When the pressing operating member is in a high position, the limit member is aligned with the clearance channel, and the reversing member and the reversing mating member are spaced a certain distance apart along the axial direction; when the pressing operating member is in a low position, the limit member passes through the clearance channel, and the reversing member and the reversing mating member cooperate to drive the low-position positioning member to rotate around the axial direction through a certain angle, so that the limit member and the limit mating member are limited upward along the axial direction.

[0009] In a preferred embodiment, the rotation reversing member and the reversing mating member are the first ratchet ramp.

[0018] When the pressing operating member moves to the low position, the sealing plug seals the pressure relief hole of the leather cup, and the water pressure in the pressure holding chamber between the leather cup and the valve body increases, driving the leather cup to move downward along the axial direction of the valve body to close the water outlet;

[0019] When the pressing operating member moves to a high position, the sealing plug opens the pressure relief hole of the leather cup, and the water pressure in the pressure-holding cavity between the leather cup and the valve body is reduced, driving the leather cup to move upward along the axial direction of the valve body to open the water outlet.

[0020] In a preferred embodiment: the switching shaft and the leather cup seat on which the leather cup is installed are linked and connected, and when the switching shaft moves upward, the leather cup seat drives the leather cup to open the water outlet.

[0037] The technical scheme in the embodiment of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiment of the present invention. Obviously, the described embodiment is only a part of the embodiment of the present invention, not all of the embodiments. Based on the embodiment of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] refer to Fig.11 This embodiment provides a fixed water outlet faucet, and a push-on / off valve core 2 is assembled on the faucet body 1.

[0039] Further references Figure 1-Figure 10 The above-mentioned push switch valve core 2 includes a valve body 21, a switching shaft 22, a sealing member 23 and a push switch 24;

[0040] The push switch 24 drives the sealing member 23 to move along the axial direction of the valve body 21 through the switching shaft 22 to open or close the water outlet of the valve body 21 .

[0041] In this embodiment, the push switch 24 includes: a push operating member 241 and a low-position positioning member 242;

[0042] The pressing operating member 241 moves axially between a high position or a low position under the action of an external force; the pressing operating member 241 includes a rotation reversing member 2411 for cooperating with the low-position positioning member 242, and a limiting member 2412 for locking with the low-position positioning member 242;

[0043] The low-position positioning member 242 includes a reversing fitting member 2421 and a limiting fitting member 2422 arranged vertically along the axial direction, and a clearance passage 2423 penetrating along the axial direction;

[0044] like Figure 8 As shown, when the pressing operating member 241 is at a high position, the limiting member 2412 is aligned with the clearance channel 2423, and the reversing member 2411 and the reversing matching member 2421 are spaced a certain distance apart along the axial direction; Fig. 9 As shown, when the pressing operating member 241 is in the low position, the limiting member 2412 passes through the clearance channel 2423. Fig.10 As shown, the reversing member 2411 cooperates with the reversing matching member 2421 to drive the low-position positioning member 242 to rotate around the axial direction by a certain angle, so that the limiting member 2412 and the limiting matching member 2422 are limited upward along the axial direction.

[0045] The above-mentioned push switch 24 can realize the switching of the push operating member 241 between the high position and the low position by means of two components, namely, the push operating member 241 and the low position positioning member 242 .

[0046] Specifically, in this embodiment, the rotation reversing member 2411 includes a plurality of first ratchet inclined surfaces 24111, and the reversing mating member 2421 includes a plurality of first ratchet mating inclined surfaces 24211. The plurality of first ratchet inclined surfaces 24111 and the plurality of first ratchet mating inclined surfaces 24211 cooperate to drive the low-position positioning member 242 to rotate around the axis by a certain angle. The low-position positioning member 242 is a rotating ratchet, and a plurality of ratchet blocks are arranged on its side wall at intervals along the circumferential direction; the clearance channel 2423 is formed between two adjacent ratchet blocks;

[0047] The reversing fitting 2421 is disposed on a side of the ratchet block facing the pressing operating member 241 .

[0048] The limiting member 2412 includes a plurality of second ratchet inclined surfaces 24121 , and the limiting matching member 2422 includes a plurality of second ratchet matching inclined surfaces; the limiting matching member 2422 is disposed on a side of the ratchet block away from the pressing operating member 241 .

[0049] The pressing operating member 241 is provided with a plurality of convex ribs along the circumferential direction below the rotating reversing member 2411 along the axial direction; the plurality of convex ribs form the limiting member 2412, and the upper surface of the limiting member 2412 along the axial direction is provided with the second ratchet inclined surface 24121.

[0050] During operation, the pressing operating member 241 is first pressed, and the convex rib enters the rotating ratchet 242 along the clearance channel 2423; the rotating ratchet 242 remains stationary, and the pressing operating member 241 moves downward along the axial direction. Fig. 9 As shown in FIG. 2 , when the pressing member 241 moves to the point where the first ratchet inclined surface 24111 of the rotating reversing member 2411 contacts the first ratchet matching inclined surface 24211 of the reversing matching member 2421, the rib has passed through the clearance channel 2423. The squeezing force generated by the squeezing of the ratchet inclined surface and the ratchet matching inclined surface will push the rotating ratchet 242 to rotate. After the rotating ratchet 242 rotates past a first ratchet inclined surface, the pressing member 241 and the rotating ratchet 242 are released from the squeezing fit. Fig.10 As shown, after the user releases the pressing operating member 241, the convex rib can be connected with the ratchet block through the second ratchet inclined surface and the second ratchet matching inclined surface to limit the pressing operating member 241, thereby fixing the pressing operating member 241 in a low position.

[0051] This embodiment further includes a working spring 25, one end of which is fixed on the valve body 21, and the other end of which is in contact with the pressing operating member 241; when the pressing operating member 241 is in a low position or a high position, the working spring 25 is always in a compressed state, so that the pressing operating member 241 is in a high position and is pressed against the valve body 21, so that the pressing operating member 241 will not shake.

[0052] In this embodiment, in order to realize the linkage between the push switch 24 and the switching shaft 22, the push operating member 241 and the switching shaft 22 are connected by a lifting rod 26. Specifically, the push operating member 241 is provided with a through channel along the axial direction, and the inner wall of the through channel extends a circle of limiting bosses along the radial direction; the upper end of the lifting rod 26 extends a limiting surface radially outward. In this way, the end of the lifting rod 26 can pass through the limiting boss, and then can be linked downward along the axial direction of the push operating member 241 through the limiting surface and the limiting boss. In addition, in order to realize the linkage connection between the lifting rod 26 and the switching shaft 22, the lower end of the lifting rod 26 is an open surface, which is connected to the installation cavity in the lifting rod 26. The upper end of the switching shaft 22 extends into the installation cavity through the opening surface and can be fixedly connected with the lifting rod 26.

[0053] In addition, in this embodiment, in order to ensure that the sealing member 23 can seal the water outlet in the water-off state, a water-off spring 27 is further provided between the valve body 21 and the lifting rod 26. By relying on the elastic restoring force of the water-off spring 27, the lifting rod 26 can be fixed in the water-off position, thereby allowing the sealing member 23 and the water outlet to be reliably sealed.

[0054] In this embodiment, the sealing member 23 is a leather cup 231 and a sealing plug 232 arranged at the lower end of the switching shaft 22; when the pressing operating member 241 moves to the low position, the sealing plug 232 seals the pressure relief hole of the leather cup 231, and the water pressure in the pressure holding chamber 235 between the leather cup 231 and the valve body 21 increases, driving the leather cup 231 to move downward along the axial direction of the valve body 21 to close the water outlet;

[0055] When the pressing operating member 241 moves to a high position, the sealing plug 232 opens the pressure relief hole 233 of the leather cup 231, and the water pressure in the pressure holding cavity between the leather cup 231 and the valve body 21 decreases, driving the leather cup 231 to move upward along the axial direction of the valve body 21 to open the water outlet.

[0056] In this embodiment, the switching shaft 22 and the leather cup seat 234 on which the leather cup 231 is installed are linked and connected. When the switching shaft 22 moves upward, the leather cup seat 234 drives the leather cup 231 to open the water outlet. Through the linkage between the leather cup seat 234 and the switching shaft 22, when the switching shaft 22 moves upward, the leather cup seat 234 moves upward accordingly to drive the leather cup 231 to open the water outlet, thereby ensuring that the water outlet can also be opened when pressed, and ensuring a large flow rate at low pressure. Specifically, the side wall of the switching shaft 22 extends radially outward to form a boss, and a buckle structure is provided on the leather cup seat 234. Through the boss and the buckle structure, the switching shaft 22 can drive the leather cup seat 234 to move upward together.
