Problems solved by technology

[0003] Usually, the hot and cold water are mixed by people operating the handle, so that people cannot have an intuitive understanding of the degree of coldness and heat of the water. When using it, they need to be careful. Effective control can easily cause overcooling or overheating, which will affect people's comfort

Embodiment 1

[0040] Embodiment one, as figure 1 As shown, the outlet pipe 11 is provided with an expansion section 2, and the expansion section 2 is used to allow the water flow to leave a certain gap between the expansion section 2 and the faucet body 1, so that the expansion section 2 expands, wherein the expansion section 2 Made of rubber, it has sufficient elasticity, and the structure of the expansion section 2 is corrugated. When the normal water flow passes, the expansion section 2 maintains a stable shape. If the water outlet 12 of the water outlet pipe 11 is closed by the switch valve 15, the internal water flow can accumulate, and the pressure will gradually expand the expansion section 2, so that the internal water flow The volume becomes larger. The expansion section 2 made of rubber can ensure its stable expansion and contraction functions, and the corrugated structure can greatly strengthen the contraction life of the expansion section 2 made of rubber, which avoids frequent...

Embodiment 2

[0041] Embodiment 2. The inner diameter of the expansion section 2 is larger than the outlet pipe 11 and is made of freely deformable soft material, such as a plastic film. Although it is not elastic, it is easy to deform and can be folded and opened freely. The expansion section 2 is wrapped with an elastic ring 21 for driving the expansion section 2 to keep the diameter of the water outlet pipe 11 consistent. The elastic ring 21 is made of rubber and has sufficient resilience. The structure of the expansion section 2 itself is relatively large. Under the action of normal water flow, the elastic ring 21 allows the driving expansion section 2 to shrink to a structure that is basically the same size as the outlet pipe 11. After the water outlet 12 of the water outlet pipe 11 is closed by the switch valve 15, the elastic ring 21 will be driven to expand when the water pressure is relatively high, so that the expansion section 2 is expanded. The soft material can be opened and fo...

Abstract

The invention discloses a faucet with the constant outlet water temperature. According to the technical scheme, the faucet is characterized by comprising a faucet body, a water outlet pipe and a handle used for controlling opening and closing of the water outlet pipe are arranged in the faucet body, a water outlet is formed in one end of the water outlet pipe, and the faucet is provided with a cold water inlet pipe and a hot water inlet pipe and further comprises a controller, a temperature sensor located in the water outlet pipe and a switch valve located at the water outlet; an expanding section for water flow to pass through is arranged in the water outlet pipe, and an electric control valve is arranged between the water outlet pipe and a whole of the cold water inlet pipe and the hot water inlet pipe; after the controller receives temperature signals of the temperature sensor, the water outlet amount of the cold water inlet pipe and the water outlet amount of the hot water inlet pipe are adjusted through the electric control valve; and after the temperature is appropriate, the switch valve is opened to achieve water outlet. In this way, it can be guaranteed that the outlet water flow is at the appropriate temperature all the time, and undercooling and overheating can be avoided.

Description

technical field [0001] The invention relates to sanitary ware, in particular to a faucet with constant water outlet temperature. Background technique [0002] Faucets are widely used in our daily life, just like washing hands and other purposes. When the faucet is connected, it will be connected with the cold water pipe and the hot water pipe. When the faucet is turned on, the hot water and the cold water can flow out together, and the mixed cold and hot water will form warm water, which can make people clean more comfortably. [0003] Usually, the hot and cold water are mixed by people operating the handle, so that people cannot have an intuitive understanding of the degree of coldness and heat of the water. When using it, they need to be careful. Effective control can easily cause overcooling or overheating, which affects people's comfort in use. Contents of the invention [0004] In view of the deficiencies in the prior art, the purpose of the present invention is to ...
