Switching valve structure of drinking fountain (1)

The present invention relates to a switching valve structure, and more particularly to a switching valve structure of a drinking fountain.

According to the development of science and technology, the environment is more seriously damaged, especially the pollution of air and water, and the water resources are limited. When it is polluted, if people drink it, it will affect the health of the body, so most families will have another A water filter is added to allow the general water to be filtered through the filter for drinking or cooking. In the process of water filtration, a switching valve is provided at the water outlet for the user to directly open. The water source is used or switched to the filter to form drinking water. However, in the conventional switching valve structure, the internal water control valve is mainly composed of a water-controlled valve structure with a spherical shape, and the water control valve is spherical. Design, the roundness control is not easy in production, so the manufacturing defect rate is high, the manufacturing cost is increased, and the water control valve is accommodated in the valve casing, because the roundness cannot be produced in the valve casing for the spherical shape. The water control valve is designed, so it is necessary to install the Teflon ring block, etc., so that the water control valve of the spherical design can be used for sealing and cutting control, so that the various problems also cause the circle. ball The control valve assembly of the missing persons and other trouble.
