[0058] The raw water enters the water inlet channel from the water source inlet of the shell, enters the water gap between the filter element assembly and the waterway plate through the water inlet channel and reaches the front end of the filter. The purified water filtered by the filter element body enters the clean water channel along the central channel and the outlet pipe, and then the purified water passes through the water inlet channel, the first water flow chamber, the heating chamber inlet, the first heating chamber, the first water flow hole in turn, enters the water flow channel and triggers the heating control unit, and continues to pass through the second water flow hole, the second heating chamber, the heating chamber outlet, the second water flow chamber, the water outlet channel, the water outlet channel, and finally flows out from the water source outlet, i.e. the bubbler.

[0059] The present invention integrates the heating component and the filtering component into a shell. Compared with the traditional faucet water purifier with independently arranged filtering device and heating device, the overall volume of the faucet water purifier of the present invention is greatly reduced. The coaxial arrangement of the heating chamber and the purification chamber further reduces the radial size of the faucet water purifier. The raw water is first filtered through the purification chamber, and the purified water after filtration enters the heating chamber for heating, which can realize both raw water filtration and purified water heating, meeting more usage requirements; when the axial height of the faucet water purifier is constant, the heating chamber is divided into two, and the purified water can repeatedly enter the heating chamber for heating, which increases the heating time of the purified water, so that the purified water can be fully heated, and the heating effect of the faucet water purifier is improved; the purified water entering the heating chamber is used to trigger the heating control unit, so that when the heating control unit is triggered, there is water in the heating chamber, avoiding dry burning.
