Referring to fig. 11, the present embodiment provides a fixed type faucet, and a push switch valve cartridge 2 is assembled on a faucet body 1.
With further reference to fig. 1-10, the push switch valve cartridge 2 described above includes a valve body 21, a switching shaft 22, a seal 23, and a push switch 24;
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.
In this embodiment, the push switch 24 includes a push operation member 241, a low-position positioning member 242;
the pressing operation member 241 moves between a high position and a low position along the axial direction under the action of external force; the pressing operation member 241 comprises a rotating direction-changing 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;
the low-position positioning piece 242 comprises a reversing fitting part 2421 and a limiting fitting part 2422 which are arranged up and down along the axial direction, and a yielding channel 2423 which is arranged in a penetrating manner along the axial direction;
as shown in fig. 8, when the pressing operation element 241 is in the high position, the limiting element 2412 is aligned with the abdicating channel 2423, and the direction-reversing element 2411 and the direction-reversing matching element 2421 are axially spaced; as shown in fig. 9, when the pressing operation element 241 is located at the low position, the limiting element 2412 passes through the abdicating channel 2423, as shown in fig. 10, the direction-reversing element 2411 cooperates with the direction-reversing mating element 2421 to drive the low-position positioning element 242 to rotate around the axial direction by a certain angle, so that the limiting element 2412 and the limiting mating element 2422 limit upwards along the axial direction.
In the push switch 24, the push operation member 241 can be switched between the high position and the low position by pushing the two components, i.e., the operation member 241 and the low position positioning member 242.
Specifically, in this embodiment, the rotating direction-changing element 2411 includes a plurality of first ratchet inclined surfaces 24111, and the direction-changing mating element 2421 includes a plurality of first ratchet inclined surfaces 24211. The first plurality of ratchet inclined surfaces 24111 and the first plurality of ratchet engaging inclined surfaces 24211 cooperate to drive the low-position positioning member 242 to rotate axially through a certain angle. The low-position positioning element 242 is a rotating ratchet wheel, and a plurality of ratchet blocks are arranged on the side wall of the low-position positioning element at intervals along the circumferential direction; the abdicating channel 2423 is formed between every two adjacent ratchet blocks;
the ratchet block is provided with the reversing fitting part 2421 on the side facing the pressing operation part 241.

In operation, the pressing operation element 241 is firstly pressed, and the convex rib enters the rotating ratchet wheel 242 along the abdicating channel 2423; the rotating ratchet 242 is held stationary and the pressing operation piece 241 is moved downward in the axial direction. As shown in FIG. 9, when pressing operator 241 moves until first ratchet ramp 24111 of rotating reverser 2411 contacts first ratchet mating ramp 24211 of reversing mating element 2421, the rib has passed through abdicating channel 2423. The pressing force generated by the pressing of the ratchet inclined plane and the ratchet matching inclined plane can push the rotating ratchet wheel 242 to rotate, the pressing operation part 241 and the rotating ratchet wheel 242 are released from the pressing fit after the rotating ratchet wheel 242 rotates by a first ratchet inclined plane, as shown in fig. 10, after a user releases the pressing operation part 241, the convex rib can be matched and limited with the ratchet block through the second ratchet inclined plane and the second ratchet matching inclined plane, and therefore the pressing operation part 241 is fixed at a low position.
The present embodiment further includes an operating spring 25, one end of the operating spring 25 is disposed on the valve body 21 as a fixed end, and the other end of the operating spring abuts against the pressing operation member 241; when the pressing operation member 241 is at the low position or the high position, the operating spring 25 is always in a compressed state. So that the pressing operation member 241 abuts against the valve body 21 at a high position, and thus the pressing operation member 241 does not shake.
In the present embodiment, the push operation member 241 and the switching shaft 22 are connected by the pull rod 26 in order to realize the linkage of the push switch 24 and the switching shaft 22. Specifically, the pressing operation member 241 is provided with a through channel along the axial direction, and a circle of limit boss extends from the inner wall of the through channel along the radial direction; the upper end of the lifting rod 26 extends outwards along the radial direction to form a limiting surface. Therefore, the tail end of the lifting rod 26 can penetrate through the limiting boss and then can be connected with the limiting boss in a linkage mode downwards along the axial direction of the pressing operation piece 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 and is communicated with the installation cavity in the lifting rod 26. The upper end of the switching shaft 22 is inserted into the mounting cavity through the opening surface and then fixedly connected with the lifting rod 26.
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 disposed between the valve body 21 and the lifting rod 26, and the lifting rod 26 can be fixed at the water-off position by the elastic restoring force of the water-off spring 27, so that the sealing member 23 and the water outlet can be reliably sealed.
In this embodiment, the sealing element 23 is a cup 231 and a sealing plug 232 disposed at the lower end of the switching shaft 22; when the pressing operation piece 241 moves to the low position, the sealing plug 232 seals the pressure relief hole of the leather cup 231, the water pressure stored in the pressure relief cavity 235 between the leather cup 231 and the valve body 21 is increased, and the leather cup 231 is driven to move downwards along the axial direction of the valve body 21 to close the water outlet;
when the pressing operation piece 241 moves to the high position, the sealing plug 232 opens the pressure relief hole 233 of the packing cup 231, and the pressure relief cavity between the packing cup 231 and the valve body 21 is reduced in the pressure relief water pressure, so that the packing cup 231 is driven to move upwards along the axial direction of the valve body 21 to open the water outlet.
In this embodiment, the switching shaft 22 is linked with the cup seat 234 for mounting the cup 231, and when the switching shaft 22 moves upward, the cup seat 234 drives the cup 231 to open the water outlet. Through the linkage of the leather cup seat 234 and the switching shaft 22, when the switching shaft 22 moves upwards, the leather cup seat 234 moves upwards along with the leather cup seat to drive the leather cup 231 to open the water outlet, so that the water outlet can be opened when the leather cup seat is pressed against the switching shaft, and the large flow rate at low pressure is ensured. Specifically, the side wall of the switching shaft 22 extends outward in the radial direction to form a boss, and the leather bowl seat 234 is provided with a fastening structure, so that the leather bowl seat 234 is driven to move upward together when the switching shaft 22 moves upward through the boss and the fastening structure.
