Description
Technical Field
[0001] The utility model relates to the technical field of bathroom products, in particular to a double-control faucet. Background Art
[0002] Common faucet products are generally controlled by mechanical switches to control water flow / stop, or automatic induction to control water flow / stop. At present, there are also some manual / automatic combined faucets on the market that can realize mechanical control and induction control. The above faucets have relatively simple functions, such as common manual / automatic combined faucets. When using induction control, the detection module needs to detect the opening and closing state of the mechanical switch. For example, if the mechanical switch is detected to be turned on by the magnetic sensor and magnetic parts of the detection module, then the induction control automatic water flow needs to detect that the mechanical switch is turned off. If the mechanical switch is detected to be turned on, the induction control needs to stop the water flow. However, this automatic and manual combined water flow control method can only be used for water flow without water temperature adjustment. If the water temperature is to be adjusted, the handle needs to have two degrees of freedom. Rotate the handle of the mechanical switch to adjust the temperature and swing the handle to open the water flow. At present, one of the magnetic parts and magnetic sensors of the detection module is installed on the faucet, and the other is installed on the handle. The faucet will not rotate with the handle. If the rotation method is used, the two will be staggered and the mechanical switch of the faucet cannot be sensed. The opening state of the faucet mechanical switch may appear, and the problem of manual water flow induction and water flow at the same time may occur, and the control logic is chaotic.
