{Hot water safety coke valve}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hot water safety cock for a cold and hot water machine, and more particularly, to a hot water safety cock for a new cold / hot water machine that can easily assemble main components and prevent loss after assembly.

Generally, a cold water purifier (cold / hot water generator) is provided with a cock valve which can supply purified water divided into cold water and hot water. Such a cock valve may take cold water or hot water by the user pulling or pushing the intake lever to open the cold and hot water passages.

However, in the case of hot water, since the temperature is higher than 90 degrees, there is a risk of a safety accident such as burning by hot water due to inadvertent use in the absence of a separate safety device, and various types of cork valves Is being developed.

In the case of a hot water safety cock in a normal hot water purifier cork valve, unlike a cold water cork, the hot water does not come out even if the water intake lever is pressed, and the intake lever can be operated only when the push button located in front of the intake lever is pressed So as to prevent safety accidents such as burns caused by hot water. That is, in the case of a hot water safety cock, the water intake lever is pushed only when the push button located in front of the intake lever is pressed, so that the water is safely used without being burned by the hot water.

However, conventionally, there is a problem that the push button is easily released when the hot water safety cock is assembled after being assembled. If the pushbutton is easily released, there is a problem that the hot water safety cock must be changed again.

In addition, there is a problem that assembly and disassembly of the shaft portion in the shaft and the sealing member operated in conjunction with the intake lever are not easy, and it is difficult to replace the shaft portion and the entire other portion must be replaced.
