Intelligent temperature-control water faucet

Abstract

The invention discloses an intelligent temperature-control water faucet. A main control module is adopted to drive motors to control a thermostatic valve and a switching valve, so that the control over outgoing water and constant temperature is achieved; a water temperature sensor is arranged to detect the water temperature in a mixed water cavity in real time, and the main control module controls the rotation position of the thermostatic valve according to the feedback water temperature, so that thermostatic adjustment for a specified temperature is achieved, and the temperature adjustment is precise; by means of the dynamic temperature adjustment mode, it is guaranteed that the temperature of the outgoing water is constant, a touch induction display circuit is used for conducting control and state display, and the experience feeling of a user is good; a temperature upper limit sensor is arranged to conduct monitoring on the temperature upper limit of the outgoing water, and when the temperature upper limit sensor induces that the water temperature is larger than the threshold value, the main control module controls the switching valve to shut off and stop water outgoing. According to the intelligent temperature-control water faucet, double safety temperature guarantees including the temperature upper limit adjustment guarantee and the outgoing water temperature limit guarantee are arranged, and even if a cold water inlet and a hot water inlet are reversely connected with each other by mistake, it can be more reliably guaranteed that a user is not scalded by hot water through the outgoing water temperature limit guarantee.

Description

technical field [0001] The invention relates to a faucet, in particular to an intelligent temperature-controlled faucet. Background technique [0002] At present, the faucets sold on the market are generally mechanical faucets and induction faucets with electromagnetic valves to control the water discharge. These two kinds of faucets have deficiencies. For example: not hygienic enough, easy to be polluted by secondary pollution, prone to scale blockage, short mechanical life, simple function, inaccurate control of outlet water temperature, easy to burn, etc. People usually need to test the temperature several times in the process of adjusting the water temperature in use to adjust the outlet water temperature. Feel very inconvenient. At present, there are also faucets that use thermostatic valves for electronic temperature regulation, that is, use thermistors to control the mixing ratio of hot and cold water.

Problems solved by technology

For example: not hygienic enough, easy to be polluted by secondary pollution, prone to scale blockage, short mechanical life, simple function, inaccurate control of outlet water temperature, easy to burn, etc. People usually need to test the temperature several times in the process of adjusting the water temperature in use to adjust the outlet water temperature. feel very inconvenient

At present, there are also faucets that use thermostatic valves for electronic temperature regulation, that is, use thermistors to control the mixing ratio of hot and cold water. Constant temperature adjustment, but the accuracy of water temperature adjustment is not high, and when the cold and hot water inlets are connected incorrectly and reversed, the proportion control of cold and hot water is reversed, and there will be a failure of the outlet water temperature to be too high or too low, and there is a safety hazard of scalding the user
