Problems solved by technology

[0002] The faucet is an important component in the water supply pipeline. It is used to open and close the waterway and adjust the flow. In order to realize the function of opening and closing the waterway, the existing faucet generally uses a valve core that rotates left and right or up and down. This type of valve core Not only does it need to install a matching handwheel or handle to drive the valve core to open, which leads to an increase in cost, but also the valve core is easy to wear when opening and closing the waterway, which shortens the service life of the valve core

Abstract

The invention discloses a press key type switch valve core, which comprises a casing and a base, wherein the base is arranged at the bottom of the casing, wherein a press key, a gear inner liner, a gear support frame, a linkage small shaft, a water stop spring seat, a water stop press block and a reset spring are arranged inside the casing; a compression spring is arranged between the lower end of the linkage small shaft and the water stop spring seat; the gear support frame is connected with the reset spring and is provided with a gear block used for gear shifting; a penetrated water outlet passage is formed in the middle part of the base; a plurality of water inlet holes communicating with an upper end opening of the water outlet passage are formed on the periphery of the lower part of the base; a filtering screen covers the outer side of the water inlet hole; a diaphragm covers the upper end opening of the water outlet passage; the diaphragm is connected into a whole with a pressure relief base; the middle part of the diaphragm is provided with a water passing passage communicating with the water outlet passage; the diaphragm is provided with a water guide hole communicating with the water inlet hole; the water stop press block downwards moves to press the upper end opening of the water passing passage so as to close the water passing passage.

Description

technical field [0001] The invention relates to the field of bathroom products, in particular to a push-button switch valve core. Background technique [0002] The faucet is an important component in the water supply pipeline. It is used to open and close the waterway and adjust the flow. In order to realize the function of opening and closing the waterway, the existing faucet generally uses a valve core that rotates left and right or up and down. This type of valve core Not only does it need to install a matching handwheel or handle to drive the valve core to open, which leads to an increase in cost, but also the valve core is easy to wear when opening and closing the waterway, which shortens the service life of the valve core. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides a push-button switch valve core, which is easy to use, has little wear and long service life. [0004] The technical solution...
