The magnetic sensor 42 is installed in the first purified water chamber 221 and located on the outer wall of the water inlet pipe body 212 near the fixing portion 2161, and the magnetic sensor 42 senses the magnetic induction intensity between the first magnet 2163 and the second magnet 2164 to output a magnetic induction signal. The input end of the controller is electrically connected with the magnetic sensor 42, the output end of the controller is electrically connected with the gas path electromagnetic valve, and the controller responds to the magnetic induction signal to compare with the preset magnetic induction intensity and controls the gas path electromagnetic valve to be opened and closed according to the comparison structure.

When water enters the water inlet pipe body 212, the first magnet 2163 is close to the second magnet 2164 so that the magnetic induction intensity between the first magnet 2163 and the second magnet 2164 is increased, and when the magnetic induction intensity is larger than the preset magnetic induction intensity in the controller, the controller controls the gas circuit electromagnetic valve to be started so as to enable the gas inlet pipe 41 to enter the air; when water inflow stops in the water inflow pipe body 212, the first magnet 2163 is far away from the second magnet 2164 so that the magnetic induction intensity between the first magnet 2163 and the second magnet 2164 is reduced, and when the magnetic induction intensity is smaller than the preset magnetic induction intensity in the controller, the controller controls the air path electromagnetic valve to be closed so as to close the air inlet pipe 41.

Referring to fig. 9 and 10, in the present embodiment, a one-way air inlet 43 is disposed at a connection point of the air inlet pipe 41 and the inner fixing pipe 21, and the one-way air inlet 43 includes a fixing seat 431, a mounting cover 432, and a diaphragm type one-way valve 433.

The fixing seat 431 is fixedly disposed on the inner fixing pipe 21, and the mounting cover 432 is fixedly disposed on the intake pipe 41. A one-way cavity 434 for communicating the air inlet pipe 41 and the first liquid mixing cavity 211 is formed in the fixing seat 431 and the mounting cover 432. The fixing seat 431 is provided with an air outlet opening for communicating the one-way cavity 434 with the mixing chamber, and the mounting cover 432 is provided with an air inlet opening for communicating the one-way cavity 434 with the air inlet pipe 41, so that the one-way cavity 434 can communicate the air inlet pipe 41 with the mixing chamber.

Referring to fig. 10 and 11, the diaphragm check valve 433 is clamped between the fixing seat 431 and the mounting cover 432, and the diaphragm check valve 433 opens and closes the check cavity 434 in a one-way manner. Specifically, the diaphragm type check valve 433 is made of hard fluoroplastic, and the diaphragm type check valve 433 includes a pressure receiving portion 4331, a connecting portion 4332 and a sealing portion 4333 which are sequentially arranged from inside to outside. The pressure receiving portion 4331 is provided in an annular shape, and the pressure receiving portion 4331 is interposed between the holder 431 and the mounting cover 432. The connecting portion 4332 and the sealing portion 4333 are located in the unidirectional cavity 434, the sealing portion 4333 is arranged in a disc shape, and the diameter of the sealing portion 4333 is larger than that of the air inlet opening, so that the sealing portion 4333 opens and closes the air inlet opening. The number of the connecting portions 4332 is three, and the three connecting portions 4332 are circumferentially arranged at equal intervals around the axis of the pressure-receiving portion 4331. The connection portion 4332 has at least one bent section in the circumferential direction so that the connection portion 4332 can extend in the circumferential direction without being excessively deformed.

The implementation principle of the dissolved air faucet in the embodiment of the application is as follows:

(1) when outputting the purified water: the purified water opening and closing piece 32 is opened, and the purified water passes through the second water passing cavity 12, the first purified water cavity 221 and the second purified water cavity 2321 in sequence and then flows out from the water outlet of the purified water output pipe 234;

(2) when the mixed liquid is output: when the clean water opening and closing member 32 is opened, after the clean water passes through the first water passing cavity 11, the water flow pushes the sliding part 2162 to move towards the direction close to the fixed part 2161 so as to open the water inlet 2151, and then the clean water enters the liquid mixing pipe 213 through the water inlet pipe 212, at this time, the sliding part 2162 drives the second magnet 2164 to close to the first magnet 2163 so as to increase the magnetic induction between the first magnet 2163 and the second magnet 2164, and when the magnetic induction is greater than the preset magnetic induction in the controller, the controller controls the gas circuit electromagnetic valve to start so as to allow the ozone to enter through the gas inlet pipe 41, the ozone enters the liquid mixing pipe 213 through the one-way gas inlet member 43 to be mixed with the clean water in the liquid mixing pipe 213, so as to generate ozone water, and the ozone water then passes through the second liquid mixing cavity 2311 and finally flows out from the water outlet of the liquid mixing output pipe 233.
