The present invention relates to a safety cock valve, and more particularly, to a safety cock valve provided in a cold / hot water purifier, a cold / hot water dispenser, and the like.

The water purifier is a device made to purify raw water by filters and / or membranes, store it in a storage tank, and take the purified water to drink it with confidence. In such a water purifier, a cold water tank for cooling and storing purified water and a hot water tank for heating and storing purified water when the cold water and hot water are taken in, and the cold water tank and the hot water tank are each cold water through separate pipes. It is connected to the intake and the hot water intake. Therefore, valves are provided at the cold water intake port and the hot water intake port, respectively, and the cold water intake lever and the hot water intake lever are provided in order to open and close the valves.

Looking at the configuration of the intake cock valve of the general cold and hot water purifier with reference to Figs. 1 and 2, the intake cock valve of the cold and hot water purifier is formed in a substantially deformed shape, the inlet 22 of the cold / hot water supply pipe (12) It has a flexible material that is installed in the valve body 20 through the valve body 20 connected to the cold / hot water tank 10 by the insertion hole 26 formed on the upper surface of the valve body 20 by Valve body 32, the lower end is coupled to the valve body 32 and the upper end is intermittent rod 34 hinged to the upper end of the intake lever 50 by the coupling pin 52, and the insertion hole 26 The upper cap 28 is coupled to the upper end of the, and the spring 36 is interposed between the upper cap 28 and the valve body (32).

Accordingly, when the cup is placed on the lower end of the intake lever 50 and the intake lever 50 is pivoted backward, the upper end of the intake lever 50 pivots to contact the upper surface of the upper cap 28 while the intermittent rod 34 is rotated. By pulling upward, the valve body 32 rises while the upper side of the side wall is curtailed, and the water intake cock valve of the cold / hot water purifier is opened.

Therefore, drinking water may be taken into the cup from the cold / hot water tank 10 through the cold / hot water supply pipe 12 and the outlet 24 of the valve body 20. When the intake cup is removed from the intake lever 50, the elastic force of the compressed spring 36 is exerted by the raising of the intermittent rod 34, and the intermittent rod 34 and the valve body 32 are lowered and the intake of the cold / hot water purifier is removed. The accommodation cock valve is closed again by the valve body 32 and the water intake lever 50 also rotates to its original position.
