Abstract

The present invention discloses a flow regulating push switch conjoined valve, comprising a valve housing, a flow regulation assembly and a push switch assembly. The valve housing has a first chamber and a second chamber which are isolated from each other, a communication channel is disposed between the first chamber and the second chamber, and a first connection pipe and a second connection pipe are devised on the valve housing. The first connection pipe has a first channel which is in communication with the first chamber and the second connection pipe has a second channel which is in communication with the second chamber. The flow regulation assembly is installed in the first chamber for regulating a flow rate of a fluid between the first channel and the communication channel. The push switch assembly is installed in the second chamber for controlling connection and disconnection of a flow path between the second channel and the communication channel.

First claim

I claim:

1 . A flow regulating push switch conjoined valve, comprising:
a valve housing comprising:
a housing main body;
a first cavity and a second cavity formed in the housing main body, the first cavity has an opening arranged vertically downwards and the second cavity has an opening arranged in a direction opposite to the opening of the first cavity, wherein a first through hole is disposed in the housing main body at a top portion of the first cavity and a second through hole is disposed in the housing main body at a bottom portion of the second cavity;
a first end cover and a second end cover, wherein the first end cover is sealingly mounted at the opening of the first cavity and cooperatively forms the first cavity, and the second end cover is sealingly mounted at the opening of the second cavity and cooperatively forms the second cavity with the housing main body;
a communication channel positioned on the valve housing between the first cavity and the second cavity;
a first connection pipe in communication with the first cavity; and
a second connection pipe having a second channel in communication with the second cavity;
a flow regulation assembly comprising:
a regulation valve rod rotatably installed in the first cavity, the regulation valve rod including a regulating block that is to change a flowable area of a first port of the communication channel or a flowable area of a first port of the first channel during rotation of the regulation valve rod;
wherein a swivel base having a rotating groove is correspondingly disposed on the first end cover, one end of the regulation valve rod is fittingly mounted in the rotating groove of the swivel base in a rotatable manner, and the other end of the regulation valve rod passes through the first through hole and extends to outside of the first cavity;
a push switch assembly comprising: a switch valve rod slidably installed in the second cavity;
a return spring to act on the switch valve rod, wherein the switch valve rod includes a plugging block that is biased to block and/or shut off a flow path between the communication channel and the second channel under an action of the return spring, and at the same time, a fluid communication between the second channel and the communication channel is achieved by press driving the switch valve rod to change a position of the plugging block; and
wherein a guide base having a guide groove is correspondingly disposed on the second end cover, one end of the switch valve rod is fittingly mounted in the guide groove of the guide base in a slidable manner, and an end opposite the one end of the switch valve rod passes through the second through hole and extends to outside of the second cavity, one end of the return spring is sleeved on the guide base and abuts against the bottom portion of the second cavity, and an end opposite one end of the return spring is sleeved on the switch valve rod and abuts against the plugging block.

2 . The flow regulating push switch conjoined valve of claim 1 , wherein the plugging block blocks and/or shuts off the flow path between the second channel and the communication channel by blocking a second port of the communication channel and/or a second port of the second channel, or by being located between the second port of the communication channel and the second port of the second channel; and wherein the fluid communication between the second channel and the communication channel is achieved when the plugging block is driven to move above or below both the second port of the communication channel and the second port of the second channel.

3 . The flow regulating push switch conjoined valve of claim 1 , wherein a limiting structure for cooperating with an upper end of the regulating block is disposed in the first cavity to achieve positioning, a lower end face of the regulating block is a helical end face structure with a gradually decreasing circumferential end face height, one of the first port of the communication channel and the first port of the first channel is correspondingly located at the regulating block, and the other one of the first port of the communication channel and the first port of the first channel is located below the regulating block.

4 . The flow regulating push switch conjoined valve of claim 3 , wherein a first sealing ring for fitting with an inner wall of the first cavity is installed on a rod body of the regulation valve rod in a limiting manner at a position above the limiting structure, so as to prevent leakage through the first through hole.

5 . The flow regulating push switch conjoined valve of claim 1 , wherein a blocking structure is disposed in the second cavity for cooperating with the plugging block to counteract the acting force of the return spring so as to limit continuous movement of the switch valve rod, a second port of the communication channel and a second port of the second channel are located at an upper side and a lower side of the blocking structure respectively, and the plugging block sealingly fits with the blocking structure.

6 . The flow regulating push switch conjoined valve of claim 5 , wherein a second sealing ring is installed on the plugging block in a limiting manner, so as to sealingly fit with the blocking structure.

7 . The flow regulating push switch conjoined valve of claim 6 , wherein a third sealing ring is further installed on the switch valve rod in a limiting manner, so as to fit with an inner wall of the second cavity to prevent leakage through the second through hole.

8 . The flow regulating push switch conjoined valve of claim 1 , wherein the opening of the second cavity is arranged vertically upwards.

9 . The flow regulating push switch conjoined valve of claim 1 , wherein the first channel, the second channel and the communication channel are all located on the same vertical plane.
