when the air pump works, air is pumped into the pressure channel 31 by the air pump, and because the caliber of an outlet 31b of the pressure channel is smaller than that of an inlet 31a of the pressure channel, the air forms certain air pressure in the pressure channel 31 to squeeze the sealing membrane 50 to deform, the sealing membrane 50 pushes the switching piece 20 to move upwards to a second position, at the moment, a lower boss 21 of the switching piece 20 pushes up a first one-way valve 60 of the first channel 11 (namely, the water supplementing channel), an upper boss 22 of the switching piece 20 breaks away from a second one-way valve 70 of the second channel 12 (namely, the water supplementing channel), at the moment, the first one-way valve 60 opens the water supplementing channel, the second one-way valve 70 closes the water supplementing channel, and the liquid pump pumps water in the water tank through the water supplementing channel;
when the air pump stops working, the spring and the sealing membrane 50 reset to drive the switching piece 20 to reset downwards, at this time, the lower boss 21 of the switching piece 20 is separated from the first one-way valve 60 of the first channel 11 (i.e. the water supplementing channel), the first one-way valve 60 resets to the first position to close the water supplementing channel, and at the same time, the upper boss 22 of the switching piece 20 re-pushes up the second channel 12.
The foaming agent and water pumped by the liquid pump are both input into the foaming device, and the outlet 31b of the pressure channel is connected with the foaming device, so that the foaming device forms gas-liquid mixture to achieve the foaming effect.
The pressure channel 31 is used for controlling the switching, and through the same liquid outlet channel 13, the liquid can be added and the water can be supplemented, so that the product cost is saved, the structure is simple, and the function is stable.
