Description

Induction tap

Technical Field

The present utility model relates to a faucet, and more particularly, to a faucet capable of switching between two modes, i.e., water discharge and manual water discharge.

Background

The existing tap mainly has two methods for controlling water outlet, one is to manually control the water outlet through a handle, and the other is to control an electric control switch such as a solenoid valve switch to realize water outlet control through signal receiving and transmitting of an induction component. Because the induction tap does not need to contact the tap body to realize the switch of the tap, the induction tap is convenient to use and is beneficial to keeping the surface of the tap clean. There are two modes of sensing faucets. One is a long water outlet mode, in which the faucet is turned on once by sensing, and turned off again by sensing, for example, when the faucet is touched at a certain position, the faucet is turned on, and when the faucet is touched at a certain position again, the faucet is turned off. The other is to sense the water outlet mode, set the condition of opening the faucet, open when meeting the condition, close when not meeting the condition. For example, the faucet is turned on when an object is sensed at a predetermined location, and is turned off when no object is sensed at the predetermined location; or the tap is opened when the tap handle or the water outlet is detected to leave the preset position, and the tap is closed when the tap handle or the water outlet is detected to be in the preset position.

Some induction water taps are combined with a valve core, the valve core is a multifunctional valve core, the multifunctional valve core can adjust water temperature and close a water path, and an induction water tap structure is disclosed in Chinese patent application No. CN202110341610.8 (publication No. CN 112963608A) of the invention. The valve core can be divided into two main types according to functions, one type is a water mixing valve core, which is used for controlling the opening and closing of a water inlet waterway of cold water and hot water and adjusting the water temperature, and the other type of water mixing valve core can also be used for adjusting the water quantity. The other type is a water diversion valve core, which can control the water flow direction and a water outlet channel for distributing water flow.

Whatever kind of induction tap has the following defects, when the solenoid valve switch is damaged, water can not be induced or the tap always keeps a normal running water state and can not be normally used, so that the tap needs to be replaced, and the use cost is increased.

At present, a water tap with two modes of automatic water outlet and manual water outlet is also available, and the scheme adopted by the water tap is that a double-valve-core structure is adopted, wherein one valve core is directly communicated with a total water outlet channel of the water tap, and the other valve core is communicated with the total water outlet channel of the water tap through an induction electric control structure. Such a faucet with two water discharge modes is disclosed in chinese patent application No. CN202220312306.0 (publication No. CN 216843264U) for an induction faucet and a control method thereof. The faucet disclosed in the above patent can realize the switching of two water outlet modes, but the faucet has a plurality of valve cores, handles for operating the respective valve cores are arranged on two sides, the waterway connection is complex, the cost is high, and the state volume of the faucet is overlarge and is not attractive.
