The water supply pipeline is communicated with the water outlet pipe 12 through the valve seat 32, and the liquid bottle 36 is connected with the liquid outlet pipe 13 through the liquid pump 34.

According to the structure, in the using process of the modular double-pump type liquid feeding faucet, the upper sensing end and the lower sensing end are continuously monitored, when the upper sensing end detects that a hand is blocked, a trigger signal is sent to the controller, if the trigger signal of the lower sensing end is not received within a specified time (2 seconds in the embodiment), the liquid pump does not work, the trigger signal of the upper sensing end is obtained again, if the controller receiving the trigger signal of the upper sensing end monitors the trigger signal sent when the lower sensing end is blocked by the hand, the controller sends a liquid pump working signal to the liquid pump, the liquid pump pumps the hand sanitizer in the liquid bottle to the liquid outlet pipe, and the hand sanitizer is pumped to the water outlet end by the liquid outlet pipe and falls on the hand of a user. When the lower detection end is blocked again after the hand sanitizer is pumped for a certain time (in the implementation, the time can be 2 seconds) or the lower sensing end detects that the hand leaves, the controller sends an opening signal to the valve head. After the valve head is opened, a water source passes through the valve seat through a water supply pipeline and is led into the water outlet pipe, the water outlet end of the water faucet shell outputs water, the valve head is closed when the sensing end sensing area is separated from a user hand in a certain time, water flow is blocked in the valve seat area, and the water flow output is stopped. If only need export rivers, then the hand stretches into the induction zone of response end down, and lower response end sends valve head working signal to the controller, can make tap only go out water. In the dismouting in-process, only need with the outlet pipe of play water module, supply channel and disk seat phase separation, with drain pipe and liquid pump phase separation, can dismantle the valve body module and change, whole change efficiency improves greatly, has avoided going out water module and response module and has together disassembled the inconvenience that brings.
