The lower end of the racket 8 is not in contact with the bottom of the piston 13, but a certain space is left, so that the racket 8 moves towards the bottom of the piston 13 in the axial direction until contacting with the bottom of the piston 13 and stopping. The lower end of the piston 13 is connected with the inner side wall of the lower part of the tube 10 in a sealing and movable manner, and the piston 13 is in friction contact with the inner side wall of the tube 10, so that when the piston 13 moves up and down along the axial direction of the tube 10, the piston 13 slides on the inner side wall of the tube 10 in a friction manner and keeps in sealing contact.

The whole fine pat 8 of the plant positioned in the inner cavity 403 is sleeved on the spring 9, that is, the lower part of the fine pat 8 is sleeved on the spring 9, the upper end of the spring 9 is abutted against the limiting block 16, the lower end of the spring 9 is positioned between the fine pat 8 and the piston seat 11, the piston seat 11 is used for limiting the movement space of the piston 13 so as to prevent the piston 13 from falling off from the cylinder 10, that is, when the piston 13 moves towards the direction of the big pat 4 along the axial direction of the cylinder 10, and when the piston 13 reaches the upward limit position, the piston 13 is contacted with the piston seat 11, so that the piston 13 is further moved towards the direction of the big pat 4. The piston seat 11 is installed at the bottom of the piston 13, that is, the lower end of the piston seat 11 is in contact with the bottom of the piston 13, and the piston seat 11 is arranged along the axial direction of the fine racket 8 and is parallel to the fine racket 8.

The pull rod 12 is arranged in an inner cavity of the fine racket 8 in a hanging mode and located at one end, close to the racket cylinder 10, of the fine racket 8, the pull rod 12 comprises a protruding head 121, a cylinder 123 and an outward-protruding inclined block 124 which are sequentially connected from top to bottom along the axial direction of the fine racket 8, the direction from the top to the bottom of the large racket 4 points to the bottom of the racket cylinder 10, a clamping groove 122 which is inward along the radial direction is formed between the protruding head 121 and the cylinder 123, the clamping groove 122 is matched with an outward-protruding bulge at one end, close to the bottom of the racket cylinder 10, of the fine racket 8, the clamping groove 122 is clamped on the bulge, a movable gap is reserved between the bulge and one end, close to the bottom of the cylinder 10, of the groove 405, and therefore the pull rod 12 is hung on the fine racket 8. The projection 121 is located above the convex protrusion and the convex ramp 124 is located below the convex protrusion. The movable gap allows the fine racket 8 to move relative to the pull rod 12 along the axial direction of the fine racket 8, that is, the fine racket 8 can move along the axial direction of the pull rod 12 in advance until the protrusion contacts with one end of the groove 405 close to the bottom of the cylinder 10 and no movable gap exists, and then the fine racket 8 drives the pull rod 12 to move along the axial direction together.

The outer convex inclined block 124 is arranged obliquely towards the pistons 13 on both sides, and is in sealing contact with the pistons 13 to form a sealing inclined surface. In the initial state (i.e. also pressing on the button 1 or the outer cap 5), the outer cam 124 is in sealing contact with the piston 13, i.e. the contact surface remains a sealing ramp, so that air in the cartridge 10 below the piston 13 cannot flow into the racket 8 through the piston 13. When the racket is pressed (i.e. in use), the racket 8 drives the rod 12 to move downward along the axial direction, so that the outer protrusion inclined block 124 is separated from the sealing contact with the piston 13, a gap is formed between the outer protrusion inclined block 124 and the piston 13, that is, a gap is left between the outer protrusion inclined block 124 and the piston 13, and air in the cylinder 10 below the piston 13 can flow into the racket 8 through the gap. The above-mentioned pressing state or use state means that an external force acts on the pressing head 1 or the outer cap 5 to drive the fine blade 8 to move toward the bottom of the barrel 10 in the axial direction, and further the fine blade 8 drives the rod 12 and the piston 13 to move together toward the bottom of the barrel 10 in the axial direction.

The valve 14 is installed at the lower end of the tube 10, the suction pipe 15 is sleeved at the lower end of the tube 10, the suction pipe 15 is located below the valve 14, the valve 14 is used for preventing air in the outer tube 10 and air in the outer tube 10 from entering the tube 10 through the tube 10 from entering the suction pipe 15, and liquid in the container is sucked into the tube 10 from the valve 14 through the suction pipe 15. That is, the valve 14 functions as a one-way conduction channel, which only allows the liquid in the suction pipe 15 to flow into the lower space of the cylinder 10 through the valve 14, but not allows the reverse flow, including the reverse flow of the liquid and the gas.

In an alternative embodiment, the button head 1 includes an inner thread 101 and an outer thread 102, the outer thread 102 is located outside the upper end of the outer cap 5, and the outer thread 102 prevents the outer cap 5 from falling off the button head 1 when the button head 1 or the outer cap 5 is twisted too much. The inner thread 101 extends vertically into the inner cavity between the outer cap 5 and the racket 4 and is in sealing contact with the inner side wall of the upper end of the outer cap 5 to prevent outside air from entering the inner cavity of the outer cap 5 through the press head 1 and further entering the container connected with the outer cap 5 and located at the lower end of the outer cap 5. The press head 1 is well buckled on the outer tube through the inner buckling line 101, and the press head 1 can move towards the bottom direction of the large racket 4 relative to the outer cover 5 in the downward pressing process, namely the press head 1 can move downwards relative to the large racket 4. The outer lid 5 is prevented from falling off the push head 1 by the outer thread 102.

In an alternative embodiment, the press head further comprises a press prevention clip 3 located outside the outer cover 5 and at the lower end of the press head 1, and the upper end of the press prevention clip 3 is in contact with the lower end of the press head 1. Wherein, the upper end of the pressure-proof clamp 3 can contact with the lower end of the external buckle line 102 of the press head 1. The pressure-proof clip 3 is used to prevent the pressure button 1 from moving downward in the axial direction of the outer cap 5 during abnormal use, so as to prevent accidental squeezing out of liquid foam during abnormal use.

In practical use, the anti-press clamp 3 is detached from the outer cover 5, an external force (for example, a hand of a person applies force) is used for pressing the press head 1, so that the press head 1 enters a pressing state, the press head 1 acts on the outer cover 5, the outer cover 5 drives the large racket 4 to move towards the bottom of the cylinder 10 in the axial direction together, then the large racket 4 drives the fine racket 8 to move towards the bottom of the cylinder 10 in the axial direction, and the fine racket 8 drives the pull rod 12 to move towards the bottom of the cylinder 10 in the axial direction. Because a gap channel with a certain distance exists between the upper end of the pull rod 12 and the fine racket 8, the fine racket 8 moves towards the bottom of the cylinder 10 for a small distance in the axial direction before the pull rod 12 moves towards the bottom of the cylinder 10, and then the fine racket 8 is driven to move towards the bottom of the cylinder 10 together, so that the gap channel between the fine racket 8 and the pull rod 12 is opened, the sealed channel in a sealed state is changed into a sealed channel in an open state, and an open channel is formed. Wherein, in the process of moving the fine racket 8 in the axial direction, the spring 9 sleeved on the fine racket 8 is compressed. When the fine racket 8 moves in the axial direction and contacts with the piston 13, the fine racket 8 drives the piston 13 to move towards the bottom of the cylinder 10 in the axial direction, and the piston 13 slides along the inner side wall of the cylinder 10 in a friction mode. Because of the friction between the piston 13 and the inner side wall of the cylinder 10, the pull rod 12 will move a short distance towards the bottom of the cylinder 10 in the axial direction before the piston 13, so that the end head of the lower end of the pull rod 12 is separated from the piston 13, and the original joint between the pull rod 12 and the piston 13 is opened for sealing, that is, the pull rod 12 and the piston 13 are not in contact any more, so that the air between the valve 14 and the piston 13 can be discharged from the piston 13 into the pull rod 12, and further discharged to the placing area 401 through the open channel between the pull rod 12 and the racket 8, and finally discharged to the outside through the pressing head 1, that is, the air in the lower space of the cylinder 10 is discharged to the outside space through the open channel. The air in the space above the tube 10, i.e., the air in the space between the large racket 4 and the tube 10, passes through the bone gap between the large racket 4 and the small racket 8 and is finally discharged from the pressing head 1 to the external space. In this process, because enclosing cover 5 drives 4 downstream of clapping greatly, and because of blade 6 stretches into in 4's of clapping greatly recess 405 for 4 drive 6 downstream of clapping greatly, blade 6 receives stopper 16 effect, and makes blade 6 and clap greatly sealed position between 4 opened, thereby makes 4 and the thin bone position gap that forms between 8 of clapping greatly. Air in the upper space of the cylinder 10 is discharged to the placement area 401 through the gap of the bone site, and finally discharged to the outside from the pressing head 1. By bone gap is meant a gap with a small gap so that air can flow through the gap.

Since the lower end of the piston 13 is connected with the inner side wall of the lower part of the tube 10 in a sealing contact manner, and the upper end of the piston 13 is connected with the fine-beat 8 in a sealing contact manner, so that the tube 10 is divided into a tube 10 upper space and a tube 10 lower space which are isolated from each other, air cannot circulate between the tube 10 upper space and the tube 10 lower space, namely, the tube 10 upper space and the tube 10 lower space are not communicated. The space above the tube 10 is the space enclosed by the fine racket 8, the large racket 4 and the tube 10, and the space below the tube 10 is the space enclosed by the valve 14, the piston 13 and the tube 10.

Specifically, the lower space of the tube 10 is the lower cavity space of the tube 10 between the valve 14 and the piston 13, and the upper space of the tube 10 is the upper cavity space of the tube 10 between the large paddle 4, the piston 13, and the fine paddle 8.

In the above, after the first pressing of the button 1 (i.e., the pressing of the button 1 from the initial position to the axial direction downward limit position), the air in the foam pump body, i.e., the air in the space below the cylinder 10, is discharged.

When the pressing of the button 1 is stopped (the hand is released), the pull rod 12 moves upward in the axial direction under the action of the spring 9 and comes into sealing contact with the piston 13 again, and after the sealing contact with the piston 13 is formed again, the pull rod 12 moves together with the piston 13 in the axial direction toward the button 1, so that the contact surface of the upper end of the pull rod 12 and the fine racket 8 forms the sealing inclined surface again. Because air is exhausted from the valve 14 to the piston 13, a pressure difference exists between the inside and the outside of the foam pump body, the pressure in the foam pump body is lower than the pressure outside the foam pump body, and a partial vacuum environment (close to the vacuum environment) is formed in the lower space of the cylinder 10. So that the pressure in the container with the suction pipe 15 is higher than the pressure in the lower space of the cartridge 10 with the valve 14, the valve 14 slightly moves in the axial direction towards the piston 13 to open, and the liquid in the container is flushed through the valve 14 via the suction pipe 15 into the lower space of the cartridge 10 to be stored.

When the pressing head 1 is pressed again (for the second time), the above movement is repeated, that is, air in the lower space of the cylinder 10 is discharged to form a partial vacuum environment, and then the liquid is sucked into the suction pipe 15, flushed out of the cylinder 10 and discharged to the lower space of the cylinder 10. However, the difference is that when the pressing head 1 is pressed for the second time, the liquid stored in the lower space of the cartridge 10 is discharged this time. Specifically, liquid stored in the lower space of the tube 10 is discharged into the inner cavity of the fine racket 8 positioned above the piston 13 through the piston 13, then discharged into the placing area 401 through an open channel between the pull rod 12 and the fine racket 8, and mixed with air discharged into the placing area 401 through the bone gap, the liquid and the air are mixed to form a gas-liquid mixture, the gas-liquid mixture is foamed through the rubbing net 2 to form foam, the foam is discharged to the outside through the pressing head 1 (a channel is arranged in the middle of the pressing head 1), and accordingly, the liquid is pressed to form the foam and the foam is discharged. Wherein, the rubbing net 2 is provided with meshes to form a net structure with small holes, and the gas-liquid mixture is foamed to form fine foam through the mesh effect.

The above is the process of forming foam by pressing liquid, that is, pressing to squeeze out the liquid in the container to form foam, the first pressing can discharge air in the foam pump body and store the liquid in the lower space of the cylinder 10, and the second pressing can discharge the stored liquid to form foam. Since the lower space of the cartridge 10 can be made large, for example, the volume of the lower space can be designed to be 3.0CC, so that a large amount of foam can be discharged by one pressing.

When the pressing of the outer cap 5 is stopped (for example, releasing the hand), since air above the cylinder 10 has been discharged, the pressure outside the foam pump body is higher than the pressure in the space above the cylinder 10 and the pressure inside the container, so that the outside air first enters the space above the racket 4 through the gap between the pressing head 1 and the outer cap 5. A part of air entering the space above the big racket 4 enters the container through the small hole at the upper part of the tube 10, so that the pressure inside and outside the container is balanced again to realize the reciprocating use. In the rebound process of the spring 9, a gap is formed between the pushing blade 6 and the limiting block 16, so that the other part of air flowing into the upper space flows into a bone gap between the large racket 4 and the small racket 8, so that the air can enter the upper space of the cylinder 10, namely the external air enters the air between the cylinder 10 and the large racket 4, and the air pressure balance is maintained. So that the next pressing of the liquid to obtain a foam can be performed. After the operations, namely the pressing-releasing-pressing operations of the press head 1, are continuously carried out, the foam liquid can be continuously pressed out until the liquid is completely consumed or the external force disappears.
