[0061] When the user presses the press head 3 downward, the press head 3 drives the first movable assembly 30, the second movable assembly 40 and the blade 50 to slide toward the suction pipe 212; at this time, the volumes of the liquid storage chamber 220 and the gas storage chamber 230 are both reduced, the pressure is increased, the first sheet body 510 and the first movable assembly 30 still maintain contact to block the air inlet 300, the second sheet body 520 and the second movable assembly 40 are separated from each other, that is, the working sealing position of the second sheet body 520 and the second movable assembly 40 is opened, the gas in the gas storage chamber 230 enters the mixing chamber 310 through the gas conveying passage 240; the elastic member 90 is pressed, at this time, the base 80 abuts against the glass bead 250, the glass bead 250 abuts against the through hole 211, the pressure of the liquid storage chamber 220 is increased, and the liquid in the liquid storage chamber 220 is pressed into the mixing chamber 310, the gas and the liquid in the mixing chamber 310 are mixed to form foam, and the foam is sprayed out from the nozzle 31 through the screen.

[0062] When the user's hand releases the press head 3, the elastic member 90 releases the elastic potential energy, the press head 3 rebounds upward, the volumes of the gas storage chamber 230 and the liquid storage chamber 220 are increased, the pressure is reduced, the second sheet body 520 abuts against the second movable assembly 40 again, the liquid is prevented from flowing back into the gas storage chamber 230, the pressure in the gas storage chamber 230 is less than the external air pressure, the first sheet body 510 is separated from the first movable assembly 30, the air inlet 300 is opened, and the external air enters the gas storage chamber 230 through the air inlet 300; the elastic member 90 is stretched, the pressure in the liquid storage chamber 220 is reduced, the pressure in the gas storage chamber 230 is less than the external pressure, the external pressure is derived from the liquid pressure in the volume in which the suction pipe 212 is immersed, the liquid is pressed into the liquid storage chamber 220 through the suction pipe 212, at this time, the glass bead 250 is pushed open by the liquid, the base 80 slides upward relative to the pull rod 60, and when the internal and external pressures of the liquid storage chamber 220 reach balance, the elastic member 90 returns to the original state.

[0063] When the press head 3 is pressed again, the liquid stored in the liquid storage chamber 220 is pressed upward into the mixing chamber 310 again under the change of pressure, the gas stored in the gas storage chamber 230 is also transported into the mixing chamber 310 again under the change of pressure, and the gas and the liquid are mixed again to prepare foam.
