Description

Water valve cartridge with left and right click type operation means {Cartridge for cold water and hot water having step operation means of rotary click type}

The present invention relates to a water valve cartridge having left and right click type stage operation means, and more particularly, by allowing a lever coupled to a handle to be moved in a stepwise manner during a left and right rotation operation of the handle. The present invention relates to a water valve cartridge having left and right click type stage operation means which can easily recognize that the division is formed, and also improve the click sensitivity during operation, thereby increasing the click sound and giving the user an excellent feeling.

The water valve cartridge is widely used for faucets and the like, and is intended to supply cold water, hot water, and cold / hot mixed water at an appropriate temperature.

That is, the cold water supply and hot water supply according to the user's needs can be selectively made, and at the same time, the device for selectively supplying the mixed water with the appropriate temperature control as needed.

Most water valve cartridges having such a function are configured to discharge cold water, hot water, and mixed water through lever operation.

In other words, if the lever is rotated up or down and then rotated to one side, the cold water is discharged. If the lever is rotated in the opposite direction, the hot water is discharged. If the lever is properly adjusted, the mixed water of the cold and hot water is discharged.

By the way, in the conventional water valve cartridge, only the mixed water temperature control function is implemented when the lever is operated, and there is no function of separately distinguishing the cold water section and the mixed water section. Therefore, even when the use of cold water is enough to use the mixed water while not aware of it can be a waste of unnecessary hot water.

In order to prevent this, it is possible to move the cold water section and the mixed water section step by step, while reducing the waste of hot water if the structure that can recognize the cold water section and the mixed water section is adopted.

Therefore, the present applicant has a utility model for a water valve cartridge that makes it easy to recognize that the cold water section and the mixed water section are formed by allowing the lever coupled to the handle to be moved step by step when the handle is rotated left and right. He applied for registration and registered as Utility Model Registration No. 20-0465948.

However, in the case of the above technology, since the protrusions are formed on the housing itself, there is a problem in that the click sensitivity is lowered and the click sound is slightly less during operation, and the present inventors have come to propose a structure that compensates for this.
