The housing 11 has a first cavity 113 and a first inlet 1111 and a first outlet 1112 communicating with the first cavity 113. A metering assembly is located within the housing 11 and is configured to meter the flow through the first chamber 113. The body of the faucet 1 is fixedly connected to the housing 11, and has a flow channel 141, a second inlet 142 and a second outlet 143, which are connected to the flow channel 141, and the second inlet 142 is connected to the first outlet 1112.

In practical operation, the water flow of the water nozzle 1 flows into the first cavity 113 through the first inlet 1111, enters the flow channel 141 through the first outlet 1112 and the second inlet 142, reaches the second outlet 143 through the flow channel 141, and finally flows out from the second outlet 143, and when the water flow passes through the first cavity 113, the metering component meters the flow of the water flow passing through the first cavity 113, so as to facilitate the realization of the total flow passing through the first cavity 113, and further calculate the total flow passing through the water nozzle 1.

Compared with the prior art, the metering component is directly arranged on the water outlet nozzle 1, only the water quantity flowing out through the water outlet nozzle 1 is metered, the water quantity generated by the flowing of other water paths of the water purifier cannot be calculated, and the metering accuracy of the water quantity of the water outlet nozzle 1 is improved.

Wherein, the measurement component can measure the flow in the first cavity 113 based on the ultrasonic flow measurement principle, the plate hole type flow measurement principle, and the differential pressure type flow measurement principle, for example, can be an ultrasonic flowmeter, a plate hole flowmeter, a differential pressure type flowmeter, etc.

In some embodiments, referring to fig. 2 and 3, the metering assembly comprises a magnetic part 121 and a hall sensor 122, the magnetic part 121 being rotatably provided in the first cavity 113 along its own rotation axis, the hall sensor 122 being arranged in cooperation with the magnetic part 121, the magnetic part 121 being configured to spin when a water flow passes through the first cavity 113.

In actual operation, when water flows through the first cavity 113, the magnetic part 121 rotates under the impact of the water flow. The rotating magnetic part 121 generates a changing magnetic field, the hall sensor 122 senses the change of the magnetic field around the magnetic part 121 and generates corresponding pulses, and the rotating speed of the magnetic part 121 is estimated according to the number of the pulses generated by the hall sensor 122 in unit time, so that the water flow rate is estimated.

The arrangement position of the hall sensor 122 is not limited as long as it can sense the change in the magnetic field of the magnetic part 121. The hall sensor 122 may be disposed in the first cavity 113, or may be disposed outside the first cavity 113 and inside the housing 11.

In practical operation, when water flows through the first cavity 113, the impact force generated by the water flow acts on the blade 1142 to drive the blade 1142 to rotate, so as to drive the rotating shaft 1141 to rotate, thereby realizing the rotation of the magnetic part 121. At this time, a changing magnetic field is generated around the rotating magnetic part 121, the hall sensor 122 senses the change of the magnetic field around the magnetic part 121, and generates a corresponding pulse, and the rotation speed of the rotating part 114 is estimated based on the number of pulses generated by the hall sensor 122 per unit time, thereby estimating the outflow water flow rate.
