In the technical solution adopted in this embodiment, the driving handle 500 is configured to drive the water diversion assembly 400 to rotate, so that the water diversion assembly 400 is communicated with the cold water channel or the hot water channel in the water outlet assembly 300, that is, the water flow can be provided for the hot water channel or the cold water channel by the rotation of the water diversion assembly 400. When the water diversion assembly 400 is communicated with the hot water channel and provides water flow for the hot water channel, the set flow sensor 710 is utilized to detect the water flow of the water inlet channel, when the water flow reaches the hot water opening flow value, the hot water channel is provided with enough water flow, the water flow entering the hot water channel is heated by the hot water channel, the water outlet temperature of the water outlet channel is reduced, the condition that the water outlet temperature of the hot water channel is higher when the water flows through less heating is prevented, and the risk probability of scalding a user due to the higher water outlet temperature is further reduced. In addition, the flow sensor 710 in this embodiment is disposed in the water inlet channel, and can detect a higher hot water opening flow value, so as to further prevent the water outlet temperature from being too high. In addition, since the flow sensor 710 is disposed in the water inlet channel of the base 600, only the base 600 and the circuit board need to be detached during the later maintenance process, which is simple and convenient and reduces the maintenance cost.

Specifically, the heating faucet includes a faucet body 100, a housing 200, a water outlet assembly 300, a water diversion assembly 400, a driving handle 500, a base 600, and a flow sensor 710. The faucet body 100 is a water outlet structure of a heating faucet, that is, cold water or hot water flows out of the faucet body 100, and the faucet body 100 may be in a bent pipe shape, which is not particularly limited. The housing 200 provides installation space for the water outlet assembly 300, the water diversion assembly 400 and the like, can protect all the assemblies in the installation cavity, and can also improve the appearance aesthetic property of the faucet. The water outlet assembly 300 is arranged in the installation cavity and provides a hot water channel and a cold water channel, and water flowing into the hot water channel flows out of the water outlet channel after being heated, so that hot water is provided for consumers; the water flowing into the cold water channel directly flows out through the water outlet channel, so that cold water is provided for consumers. The water diversion component 400 is rotatably arranged in the mounting cavity and is used for selectively communicating a hot water channel or a cold water channel, namely when the internal water channel of the water diversion component 400 is communicated with the hot water channel, the internal water channel of the water diversion component 400 is not communicated with the cold water channel; when the internal waterway of the water diversion assembly 400 is in communication with the cold water passageway, the internal waterway of the water diversion assembly 400 is not in communication with the hot water passageway. Also, the water diversion assembly 400 is provided in the installation cavity, and water is prevented from leaking out of the housing 200. In addition, the water discharge assembly 300 and the water diversion assembly 400 are coaxially disposed, i.e., are stacked in the gravity direction, so that the water diversion assembly 400 rotates in the horizontal direction. The driving handle 500 is used for connecting the water diversion assembly 400, driving the water diversion assembly 400 to rotate in the installation cavity, one end of the driving handle 500 extends into the installation cavity, and the other end of the driving handle 500 extends out of the shell 200, so that the operation of a user is facilitated. The handle 500 is driven to rotate along the circumferential direction of the housing 200 so that the water diversion assembly 400 can be planarly shifted to select a cold water area or a hot water area.

Therefore, the flow sensor 710 in this embodiment is a hall water flow sensor, has high detection precision and better adjustability, and can adaptively adjust the hot water opening flow value before leaving the factory, so as to prevent the water outlet temperature from being too high, and improve the safety and comfort of consumers in the use process.
