In this embodiment, when the press head 3 is pressed, the liquid in the liquid storage chamber 220 is output to the mixing chamber 310 due to the decrease in the volume of the liquid storage chamber 220. At the same time, the sealing position between the vane 50 and the second movable assembly 40 is opened, the gas in the gas storage chamber 230 enters the mixing chamber 310, mixes with the liquid in the mixing chamber 310 to form foam, and is pumped out through the nozzle 31. The sealing performance is good.

[0051] In an optional embodiment, the barrel portion 20 comprises an upper barrel 200 and a lower barrel 210. The upper barrel 200 is connected to the lower barrel 210. The upper barrel 200 can be connected to the pump body portion 2 by thread connection, clamping connection, buckling connection, or the like. The top of the upper barrel 200 comprises a flange 201.

[0052] In an optional embodiment, one end of the first movable assembly 30 is sleeved in the upper cylinder 200, and the inner wall of the first movable assembly 30 abuts against the inner wall of the upper cylinder 200, and the first movable assembly 30 slides along the axial direction of the upper cylinder 200. One end of the second movable assembly 40 is sleeved in the lower cylinder 210, and the other end of the second movable assembly 40 is sleeved in the other end of the first movable assembly 30, and the second movable assembly 40 slides along the axial direction of the lower cylinder 210. The bottom of the lower cylinder 210 is provided with a through hole 211. The foam pump further comprises a sealing member arranged at the bottom of the lower cylinder 210 and abutting against the through hole 211. The sealing member can be a glass bead 250. When the glass bead 250 abuts against the through hole 211, the liquid storage chamber 220 is kept in a sealed state.

[0053] The bottom of the lower cylinder 210 is connected with a suction pipe 212, and the suction pipe 212 communicates with the through hole 211 to suck liquid.

[0055] In an optional embodiment, the blade 50 comprises a blade body 500, a first blade body 510 and a second blade body 520, the first blade body 510 and the second blade body 520 are both connected to the blade body 500, and the first blade body 510 and the second blade body 520 are located on opposite sides of the blade body 500. The first movable assembly 30 is provided with an air inlet 300, the blade body 500 is connected to the first movable assembly 30, the second blade body 520 is located between the second movable assembly 40 and the blade body 500, the second blade body 520 can abut against the second movable assembly 40 to prevent the gas in the gas storage chamber 230 from being conveyed into the gas conveying passage 240, and the second blade body 520 can be separated from the second movable assembly 40 to allow the gas in the gas storage chamber 230 to be conveyed into the mixing chamber 310 through the gas conveying passage 240. The abutting position between the second blade body 520 and the second movable assembly 40 is the working sealing position of the gas storage chamber 230. The first blade body 510 can abut against the first movable assembly 30 to block the air inlet 300, and the first blade body 510 can be separated from the first movable assembly 30 to open the air inlet 300. When the first blade body 510 is separated from the first movable assembly 30 to open the air inlet 300, the gas storage chamber 230 of the foam pump is in a relatively sealed state when the first blade body 510 abuts against the first movable assembly 30 to block the air inlet 300.

The upper end of the buckle 100 abuts against the press head 3, and the lower end of the buckle 100 abuts against the outer wall of the pump body 2, so as to prevent the press head 3 from being pressed to make the nozzle 31 spray foam.

[0059] Specific working process:

[0060] The user stretches his hand downward to press the press head 3, which drives the first movable assembly 30, the second movable assembly 40 and the vane 50 to slide toward the direction of 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, and the second sheet body 520 and the second movable assembly 40 are separated from contact, i.e. 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 squeezed, 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.

[0061] 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 and the second movable assembly 40 re-abut, which prevents the liquid 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 and the first movable assembly 30 are separated from contact, 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, and the base 80 slides upward relative to the pull rod 60, when the internal and external pressures of the liquid storage chamber 220 reach balance, the elastic member 90 returns to the original state.

[0062] When the press head 3 is pressed again, the liquid stored in the liquid storage chamber 220 is again forced up into the mixing chamber 310 under the change of pressure, and the gas stored in the gas storage chamber 230 is also again delivered into the mixing chamber 310 under the change of pressure, and the gas and the liquid are mixed again to prepare the foam.
