Cold and hot water faucet

Abstract

The invention discloses a cold and hot water faucet. The cold and hot water faucet comprises a cold and hot water faucet body, a cold water channel, a hot water channel, a water outlet channel, a cold water flow adjusting valve and a hot water flow adjusting valve. Valves are respectively arranged on the cold and the hot water channel. Screws and a screw shaft are respectively arranged on sections, intersected with the water outlet channel, of the cold water channel and the hot water channel. The screws are respectively coupled and fixed on the same screw shaft or the screws are integrated with the screw shaft. A guide wheel is arranged between the two screws and on a section, intersected with the water outlet channel, of the cold water channel and the hot water channel. When the valves are all switched on, flows of cold water and hot water are basically identical, pressure difference between the cold water and the hot water is effectively adjusted. When a user turns on other faucets on a same pipeline, only total flow is reduced, adjusted proportion between the cold water and the hot water is basically not changed, thus the temperature of water is effectively controlled.

Description

technical field [0001] The invention relates to a cold and hot water faucet. Background technique [0002] With the improvement of people's living standards, most of the faucets for domestic water use hot and cold water faucets. Generally speaking, for example, the water outlet pressure of the solar water heater comes from the height difference between the water tank and the water outlet of the solar water heater, so that the pressure of cold water and hot water is different. Even if the water temperature has been adjusted when taking a bath, it will also affect the adjusted water temperature when other people open other faucets on the same pipeline, although some cold and hot water faucets have been technically improved, as the patent number is: 201110191286.2 A kind of cold and hot water faucet , the cold water inlet channel and the hot water inlet channel are respectively integrally provided with an impeller chamber, the impeller chamber is provided with an impeller, and...

[0002] With the improvement of people's living standards, most of the faucets for domestic water use hot and cold water faucets. Generally speaking, for example, the water outlet pressure of the solar water heater comes from the height difference between the water tank and the water outlet of the solar water heater, so that the pressure of cold water and hot water is different. Even if the water temperature has been adjusted when taking a bath, it will also affect the adjusted water temperature when other people open other faucets on the same pipeline, although some cold and hot water faucets have been technically improved, as the patent number is: 201110191286.2 A kind of cold and hot water faucet , the cold water inlet channel and the hot water inlet channel are respectively integrally provided with an impeller chamber, the impeller chamber is provided with an impeller, and the impeller arranged in the impeller chamber of the cold water inlet channel is arranged on the An impeller shaft and a shaft sleeve are arranged between the impellers in the impeller chamber of the hot water inlet channel, and the impellers are respectively axially connected and fixed to the two ends of the impeller shaft. When the channel of the impeller flows through, it will drive the two coaxial impellers to rotate synchronously. Although this method can effectively adjust the water pressure difference, when only one of the cold water or hot water flows through to drive the impeller to rotate, the other is not opened. The water on the channel will generate pressure between the impeller and the valve, which will cause great resistance to the impeller, causing the impeller to rotate slowly on the open water inlet channel, so that the water flow will be reduced a lot, and it may be difficult to install the hot and cold water faucet. Some raw material belts etc. enter the hot and cold water channels or hemp threads enter the water pipes when installing tap water, which may wind the impeller and make the impeller inflexible
