When a user or external force presses the control piece and the control piece moves to a specific first position, the water passing channel is closed, the pressing on the control piece is released, the elastic piece 28 drives the control piece to reset, and at the moment, the water passing channel is opened again; when the control piece is pressed and moved to the second position, the water passing channel is closed, and when the control piece is driven to stop at the third position by the elastic piece 28 and released, the water passing channel keeps a closed state; when the control member is pressed again to move to the second position and then released, the elastic member 28 drives the control member to reset, and the water passing channel is opened again.
Wherein the first position, the second position and the third position refer to the specific positions reached by the movement of the control member, which are distributed in the axial direction of the valve housing, wherein the first position is defined by the opening and closing of the water passage, the second position is defined by whether the control member can be driven by the elastic member 28, and the water passage is always kept closed when the control member is located at the second position or the third position.
Specifically, the valve housing is composed of an upper valve housing 21 and a valve seat 24, which are fixedly connected to each other through a snap structure provided at a side and form a chamber inside.
In some embodiments, including the present embodiment, the water passage includes a water inlet, at least one primary water outlet, and at least one secondary water outlet. Of course, in other embodiments, the water passage may include a water inlet and at least one primary water outlet, and no secondary water outlet is required.
In this embodiment, the water passage provided in the valve housing has a water inlet, a main water outlet and an auxiliary water outlet; the water inlet and the main water outlet are arranged on the valve seat 24, and the auxiliary water outlet is arranged on the upper valve shell 24. In addition, in the present embodiment, the push switch valve 20 has a pilot structure, and controls the movement of the piston 23 by changing the pressure at both ends of the piston 23, thereby controlling the opening and closing of the water passage.
In other embodiments, especially when the water passage only includes a water inlet and a water outlet, the position of the piston 23 may be changed to block or separate from the water inlet or the water outlet of the water passage without using a pilot structure, in a manner that the pressing action directly acts on the piston 23 to push the piston 23 to move.
In this embodiment, the piston 23 is disposed in the valve housing, and a pilot hole 232 is formed therein, and the piston 23 is pushed by water pressure to move in the axial direction to close or open the water passage; a hydraulic chamber housing 22 is fixedly mounted within the valve housing and cooperates with the piston 23 to form a hydraulic chamber. Specifically, as shown in fig. 7, the lower half portion of the upper valve casing 21 is fixedly connected to the valve seat 24 to form a chamber, and the chamber has a water inlet and a main water outlet, and a water passage is formed between the water inlet and the main water outlet; hydraulic pressure chamber shell 22 is fixed in this cavity through the mode of block, and piston 23 sets up in hydraulic pressure chamber shell 22's downside to form the hydraulic pressure chamber with hydraulic pressure chamber shell 22 cooperation, rivers pass through the guide hole 232 on piston 23 and get into in the hydraulic pressure chamber, and piston 23 can follow the axial displacement of valve casing in certain scope simultaneously, and when it moved to the bottommost, piston 23 cut off the intercommunication of water inlet and main delivery port, and when it left the bottommost, the water inlet recovered the intercommunication with main delivery port. A Y-ring 224 is provided between the piston 23 and the hydraulic chamber housing 22 for forming a seal between the piston 23 and the hydraulic chamber housing 22; a gasket 232 is affixed to the piston 23 and is used to form a seal against the rim at the water inlet.
The movement of the piston 23 is determined by the water pressure on both sides of the piston 23, i.e. the water inlet pressure of the water inlet and the water pressure of the water pressure chamber, the water inlet pressure is kept constant under normal conditions, so that the position of the piston 23 can be changed by changing the water pressure of the water pressure chamber. In this embodiment, the control member includes a control rod 29, the control rod penetrates through the hydraulic pressure chamber housing 22 and opens or closes the communication between the hydraulic pressure chamber and the auxiliary water outlet through axial movement, specifically, a first through hole 221 is formed in the hydraulic pressure chamber housing 22 along the movement direction of the control rod 29, the first through hole 221 of the hydraulic pressure chamber forms a water path which can be communicated with the auxiliary water outlet, and the control rod 29 is switched to open and close.
The control rod 29 enters the hydraulic chamber through the first through hole 221 and has a blocking structure which blocks or moves away from the first through hole 221 by the axial movement of the control rod 29 to open or close the communication of the hydraulic chamber with the secondary water outlet. Specifically, the blocking structure on the control rod 29 is composed of a common rod body on the control rod 29 and a rod diameter reducing portion 292, the rod diameter reducing portion 292 is located at a preset position of the control rod 29, the length and the set preset position of the rod diameter reducing portion 292 are determined by a specific stroke required by the piston 23 to block the water inlet, and the diameter of the rod diameter reducing portion 292 is smaller than that of the first through hole 221, so that when the rod diameter reducing portion 292 is located at the position of the first through hole 221, a drainage hole is formed by the side wall of the first through hole 221 and the side wall of the rod body out of the rod diameter reducing portion 292, and the hydraulic pressure cavity is communicated with the auxiliary water outlet; meanwhile, the shaft body diameter of the common part of the control rod 29 is matched with the diameter of the first through hole 221, and when the control rod 29 moves within a preset movement range, the shaft body side wall of the control rod is always contacted with the side wall of the first through hole 221, so that the first through hole 221 is always blocked, and the purpose of closing the communication between the auxiliary water outlet and the water pressure cavity is achieved.
When the hydraulic pressure cavity is in a state of being communicated with the auxiliary water outlet, the pressure of the hydraulic pressure cavity is reduced, and the water pressure of the water inlet pushes the piston 23 to move towards the direction far away from the water inlet, so that the valve is opened; when the hydraulic pressure cavity is in a state of being communicated with the auxiliary water outlet in a closed mode, water flow enters the hydraulic pressure cavity through the guide hole 232 and fills the hydraulic pressure cavity, at the moment, the stress of the piston 23 on one side of the hydraulic pressure cavity is larger than that on one side of the water inlet, the piston 23 moves towards the water inlet and blocks the water inlet, and therefore the valve is closed.

In addition, a pressure cap 222 is provided between the hydraulic chamber housing 22 and the inner wall surface of the upper valve housing 21, and one end of the pressure cap abuts against the O-ring on the hydraulic chamber housing 22 and the other end abuts against the inner wall surface of the upper valve housing 21, so as to prevent the O-ring from falling.
In addition, in this embodiment, the piston 23 is provided with a second through hole, the control rod 29 enters the hydraulic chamber and then continues to pass through the second through hole, and a pilot hole 232 is formed between the rod body of the control rod 29 and the side wall of the second through hole, and the pilot hole 232 is a circular gap defined by the rod body of the control rod 29 and the side wall of the second through hole and communicates the water inlet with the inside of the hydraulic chamber. This is one way of forming pilot bore 232, and in other embodiments pilot bore 232 may be formed by opening directly into piston 23.
Furthermore, in this embodiment, the end of the control rod 29 is provided with an outwardly extending flange 291, which flange 291 abuts against the piston 23 when the control rod 29 is reset by the elastic member 28. Specifically, as shown in fig. 7, after the control rod 29 penetrates through the second through hole of the piston 23, the protruding end edge of the control rod extends outward for a distance to form a flange 291, and the distance that the flange 291 extends out is greater than the distance between the rod body of the control rod 29 and the side wall of the second through hole, so that when the control rod 29 moves in the direction away from the pressing direction, the flange 291 can abut against the piston 23, so as to apply a force to the piston 23, and help the piston 23 to move away from the water inlet.
The upper half of the switch valve 20 is pressed to control the opening and closing of the valve, and the position of the control rod 29 relative to the upper valve housing 21, and thus the position of the piston 23, is changed mainly by the action between the control member and the elastic member 28.
