Faucet with automatic temperature adjustment function

Abstract

The invention discloses a faucet with an automatic temperature adjustment function. The faucet with the automatic temperature adjustment function comprises a faucet shell base, a thermostatic valve assembly, a warm water switch valve assembly and a temperature setting valve assembly. A warm water channel, a cold water inlet and a hot water inlet are arranged in the faucet shell base. The thermostatic valve assembly comprises a thermostatic valve shell, a thermostatic valve element, a memory metal bar, a heat conducting sleeve, an elastic resetting part, an elastic sleeve and an ejector rod. The memory metal bar has the feature of the shape memory effect, and therefore the thermostatic valve element can be driven to move, the flow changes of cold water and hot water can slowly tend to be stable, and the constant-temperature effect is achieved. Compared with a conventional memory spring, the memory metal bar has the advantages of having the higher bearing capacity and the higher drivingcapacity and adapting to a high-pressure pipeline system. The relative distance between the ejector rod and the memory metal bar can be adjusted through the temperature setting valve assembly, the initial positioning of the thermostatic valve element is changed, and the temperature setting target is achieved.

Description

technical field [0001] The invention relates to the technical field of faucets, in particular to an automatic temperature-regulating faucet. Background technique [0002] The former cold and hot water faucet control system in the industry mainly includes the mode of controlling the water temperature by turning the handle left and right and the mode of installing a thermostatic valve under the faucet. The handle mode mainly adjusts the volume of hot and cold water by manually controlling the handle water, in order to achieve the purpose of controlling the water temperature. The water temperature control mode of the thermostatic valve at the front of the faucet is a mode of controlling the water temperature through the cooperation of two different devices, the faucet and the thermostatic valve. The bad thing about this mode of controlling the water temperature is that the water temperature is controlled by the human consciousness. , it may cause the water temperature to be di...

Problems solved by technology

The water temperature control mode of the thermostatic valve at the front of the faucet is a mode of controlling the water temperature through the cooperation of two different devices, the faucet and the thermostatic valve. The bad thing about this mode of controlling the water temperature is that the water temperature is controlled by the human consciousness. , may cause the water temperature to be different, it takes a long time to adjust the temperature, and the user experience is poor. However, the water temperature control mode of the faucet front thermostatic valve requires a lot of equipment, a lot of pipelines, takes up a lot of space, and after-sales installation is more troublesome.

At the same time, some existing automatic temperature-adjusting faucets cannot be applied to high-pressure pipeline systems, and high-pressure water will cause existing automatic temperature-adjusting faucets to fail
