Referring to fig. 2, 3, 5, 6, and 7, the pressing pump according to the embodiment of the present invention includes a pressing head 100, a post 200, an outer cylinder 300, a valve member 400, an inner cylinder 500, an elastic member 600, and a piston 700.

The pressing head 100 comprises a spraying head part 110 and a connecting part 120, the spraying head part 110 is connected to one side of the connecting part 120, the spraying head part 110 is provided with a first liquid outlet channel 111, the connecting part 120 is provided with a second liquid outlet channel 121, one end (a discharge hole) of the first liquid outlet channel 111 is communicated with the outside, and the other end of the first liquid outlet channel 111 is communicated with the upper end of the second liquid outlet channel 121. It is to be understood that the connecting portion 120 is substantially cylindrical. Referring to a conventional pressing pump, the nozzle head 110 is generally protruded relative to the connecting portion 120, and for convenience of transportation, storage and use, the pressing head 100 on the pressing pump can be rotated, so as to adjust the position (or angle, angular position) of the nozzle head 110; for example, when the pressing pump is mounted on the flat bottle 1000, the nozzle portion 110 of the pressing head 100 is generally adjusted to be parallel to the flat surface of the bottle 1000 (in this case, the first liquid outlet channel 111 is parallel to the flat surface of the bottle 1000) during transportation and storage, and when the pressing pump is used, the nozzle portion 110 of the pressing head 100 is generally adjusted to be substantially perpendicular to the flat surface of the bottle 1000 (in this case, the first liquid outlet channel 111 is substantially perpendicular to the flat surface of the bottle 1000) for convenient use.

The upright column 200 is connected to the lower end of the connecting portion 120, the upright column 200 is provided with a third liquid outlet channel 210, the upper end of the third liquid outlet channel 210 is communicated with the lower end of the second liquid outlet channel 121, and the pressing head 100 can drive the upright column 200 to rotate. It should be understood that the outer side wall of the upper end of the column 200 is provided with the co-rotation insertion groove 230, and the inner side wall of the connecting portion 120 (pressing head 100) is provided with the co-rotation insertion strip 122, and the co-rotation insertion strip 122 is inserted into the co-rotation insertion groove 230. The co-rotating insert strips 122 and the co-rotating slots 230 are in interference fit, and simultaneously play a role in connecting and fixing the pressing head 100 and the stand column 200 together. It should be understood that the connection between the shaft 200 and the pressing head 100 may be a detachable connection as in the present embodiment, or may be another connection, such as an adhesive, a thermal fusion connection, an integrally formed connection (i.e., the shaft 200 may be a part of the pressing head 100), and so on.

The outer cylinder 300, the lower end of the outer cylinder 300 is provided with a liquid inlet 310. The outer tub 300 is used to be connected inside the bottle 1000. The outer cylinder 300 is a basic carrier for fixing other parts of the pressing pump on the bottle 1000; meanwhile, the outer cylinder 300 isolates a part of the space inside the bottle body 1000, thereby conveniently forming a relatively independent liquid storage space 320.

The valve element 400 is located in the outer cylinder 300, the valve element 400 is arranged at the lower end of the outer cylinder 300, and the valve element 400 is used for sealing the liquid inlet 310. The valve element 400 is used for automatically closing the liquid inlet 310 at the lower end of the liquid storage space 320 when the material is discharged by pressing; when the pressing head 100 moves upward (or rebounds, returns, or resets), the valve element 400 automatically leaves the liquid inlet 310, thereby opening the liquid inlet 310. It should be understood that the specific form of the valve member 400 may vary, such as the disc valve member 400 in the present embodiment, and such as the ball valve member 400 in general. It should be understood that the valve member 400 may be made of metal or plastic.

The inner cylinder 500, the inner cylinder 500 is located in the outer cylinder 300, the inner cylinder 500 is arranged at the upper end of the outer cylinder 300, the upright post 200 is inserted in the inner cylinder 500, and the upright post 200 can move up and down relative to the inner cylinder 500. The inner cylinder 500 is arranged, so that the upper end of the inner space of the outer cylinder 300 can be conveniently sealed, a certain sealing effect on the liquid storage space 320 can be achieved, direct contact and pollution of the external environment to the liquid storage space 320 can be reduced to the greatest extent, and the inner cylinder 500 is additionally arranged, so that assembly is facilitated; on the other hand, the inner cylinder 500 is also a base carrier for the vertical column 200 to slide up and down and rotate, i.e. the outer sidewall of the inner cylinder 500 is connected to the outer cylinder 300, and the inner sidewall of the inner cylinder 500 is connected to the vertical column 200.

The outer side wall of the column 200 is provided with a sliding protrusion 220, the inner side wall of the inner cylinder 500 (the waterproof ring 570) is sequentially provided with a first sliding groove 510, a first hand-feeling protrusion 520, a pressure-proof protrusion 530 and an anti-rotation protrusion 540 along a forward rotation direction (or a first circumferential direction; and a reverse rotation direction is a second circumferential direction opposite to the first circumferential direction) of the inner cylinder 500, the first sliding groove 510 is used for allowing the sliding protrusion 220 to slide up and down, the first hand-feeling protrusion 520 is used for abutting against the outer surface of the sliding protrusion 220, the pressure-proof protrusion 530 is used for abutting against the bottom surface of the sliding protrusion 220 to prevent the sliding protrusion 220 from sliding down, and the anti-rotation protrusion 540 is used for abutting against the side surface of the sliding protrusion 220 to prevent the sliding protrusion 220 from continuously rotating relative to the inner cylinder 500. The pressing head 100 is rotated, and the pressing head 100 drives the upright post 200 to rotate; when the pressing head 100 rotates reversely, the pressing head 100 drives the upright post 200 to rotate reversely, so that the sliding convex strip 220 moves from the upper part of the pressure-proof protrusion 530 to the upper part of the sliding groove, and at the moment, the pressure-proof protrusion 530 can slide up and down along the sliding groove, so that the pressing head 100 can be pressed to drive the upright post 200 and the piston 700 to move down, and the liquid is discharged and discharged normally; when the pressing head 100 is rotated forward, the pressing head 100 drives the pillar 200 to rotate forward, so that the sliding protrusion 220 moves from above the sliding groove to above the anti-rotation protrusion 540, and the pressing head 100 cannot move downward, i.e., cannot press the pressing head 100. When the sliding protrusion strip 220 of the upright post 200 is located above the pressure-proof protrusion 530, the sliding protrusion strip 220 cannot move downward, i.e. the upright post 200 and the pressing head 100 cannot move downward and cannot press the pressing head 100, so that accidental pressing liquid discharge under the conditions of accidental touch and the like can be prevented, and the upright post is convenient to transport, store and use in daily life; when the height position of the pressing head 100 is locked (i.e. when the pressing pump cannot be pressed for discharging, or when the pressing head 100 is self-locked), only the pressing head 100 needs to be rotated, and the pressing head 100 does not need to be pressed or moved downwards in other modes, so that discharging in the locking process is caused, and materials are wasted. Furthermore, a hand feeling bulge is arranged between the sliding groove and the pressure-proof bulge 530 (or other sliding grooves), so that on one hand, a certain limiting effect is achieved, and on the other hand, a prompt and hand feeling increasing effect is achieved; that is, when the self-locking and non-self-locking state of the pressing head 100 is switched (or the discharging gear is switched), when the sliding convex strip 220 crosses the hand feeling protrusion, a certain resistance exists, and a certain limit function is inherent, so that the self-locking and non-self-locking state of the pressing head 100 cannot be switched at will when the pressing head 100 does not rotate manually; and the sliding convex strips 220 cross the hand feeling bulges, so that the user can be clearly prompted that the state of the pressing head 100 is switched by an obvious hand feeling (even a rattling sound is generated). It should be understood that, a first sliding groove 510, a first manual-feel protrusion 520 (in some embodiments, a second sliding groove, a second manual-feel protrusion, or more sliding grooves and manual-feel protrusions), a pressure-proof protrusion 530 and an anti-rotation protrusion 540 are taken as a set of height position locking structures, and along the circumferential direction of the inner tube 500, on the whole inner side wall of the inner tube 500, more sets of height position locking structures may be sequentially arranged, "sequentially", that is, after the anti-rotation protrusion 540 of the former set of height position locking structures is connected to the first sliding groove 510 of the latter set of height position locking structures; if an end-to-end structure is formed, the anti-rotation protrusions 540 of the last set of height position locking structures are connected to the first sliding grooves 510 of the first set of height position locking structures; correspondingly, corresponding to each set of height position locking structure, the upright post 200 is correspondingly provided with a sliding protruding strip 220. The rotation-preventing protrusions 540 are provided to prevent the pressing head 100 (the column 200) from continuing to rotate relative to the inner cylinder 500 after the sliding protrusions 220 rotate into the sliding grooves or the pressure-preventing protrusions 530; meanwhile, in some embodiments, the outer cylinder 300 has no particular limitation on the inner cylinder 500, and the inner cylinder 500 can rotate relative to the outer cylinder 300, so that the pressing head 100 can be rotated, and after the sliding protrusion strip 220 abuts against the rotation-preventing protrusion 540, the pressing head 100 continues to be rotated, so that the upright post 200 drives the inner cylinder 500 to rotate relative to the outer cylinder 300, and further the angular position of the pressing head 100 is changed, which is convenient for use.

One end of the elastic member 600 contacts the connection part 120 or the column 200, and the other end of the elastic member 600 contacts the inner tube 500. The elastic member 600 serves to separate the pressing head 100 from the inner cylinder 500. The elastic member 600 may be a spring, an elastic sheet, an elastic plastic member, etc., in this embodiment, the elastic member 600 is a spring-like structural member made of plastic; specifically, the elastic member 600 is made of an elastic material, and the upper and lower connection structure of the elastic member 600 is a structure extending obliquely, but not the same as the upper and lower direction (i.e., the direction in which the pressing head 100 is pressed and applied, and the direction in which the pressing head 100 moves), so as to facilitate the generation of the deformation of the elastic member 600.

The piston 700 and the piston 700 are arranged in the outer cylinder 300, the upright post 200 is connected with the piston 700, the upright post 200 can drive the piston 700 to move up and down, the piston 700 is positioned between the inner cylinder 500 and the valve 400, and the space between the piston 700 and the valve 400 is the liquid storage space 320. Alternatively, the piston 700, the valve member 400 and the outer cylinder 300 together define a liquid storage space 320, and the liquid storage space 320 can communicate with the lower end of the third liquid outlet channel 210. The outer side wall of the piston 700 abuts against the inner side wall of the outer cylinder 300, and the piston 700 can slide up and down relative to the outer cylinder 300; the inner side of the piston 700 is generally connected to the shaft 200, and the shaft 200 has a certain movement space with respect to the piston 700 (or the piston 700 with respect to the shaft 200), but when the shaft 200 moves to a greater extent with respect to the piston 700, the shaft 200 can drive the piston 700 to move together. The inner space of the outer cartridge 300 defines a reservoir space 320 with the piston 700 and the valve member 400 as boundary parts. It should be understood that the shaft 200 can move the piston 700 up and down, thereby changing the size of the liquid storage space 320; meanwhile, in the moving process of the upright column 200, the piston 700 has a certain hysteresis property relative to the upright column 200, that is, the upright column 200 can firstly move a certain distance relative to the piston 700 (at this time, the piston 700 does not move, that is, at this time, the upright column 200 cannot drive the piston 700 to move up and down), and then drive the piston 700 to move; when the upright post 200 moves relative to the piston 700, the third liquid outlet channel 210 and the liquid storage space 320 can be communicated or not communicated; specifically, in the present embodiment, when the upright post 200 moves downward relative to the piston 700, the third fluid outlet channel 210 is communicated with the fluid storage space 320, and when the upright post 200 moves upward relative to the piston 700, the third fluid outlet channel 210 is not communicated with the fluid storage space 320. More specifically, when the pressing head 100 is pressed, the pressing head 100 drives the upright post 200 to move downward together, due to the hysteresis effect of the piston 700 (when the upright post 200 starts to move, the piston 700 does not move, that is, when the pressing head 100 starts to move downward, the upright post 200 moves downward relative to the piston 700), the liquid storage space 320 is communicated with the third liquid outlet channel 210, the upright post 200 continues to move downward, and finally the piston 700 is pushed to move downward together, that is, the piston 700 moves downward relative to the inner cylinder 500, the outer cylinder 300, the bottle 1000, and other parts, at this time, the liquid storage space 320 becomes smaller, the valve 400 is pressed downward on the liquid inlet 310, so as to close the liquid inlet 310, so that the material in the liquid storage space 320 enters the third liquid outlet channel 210 (specifically, the material in the liquid storage space 320 is pressed into the suction column 710, the material enters the inner cavity at the lower end of the upright post 200 from the liquid outlet opening 711 of the suction column 710, and then enters the third liquid outlet channel of the upright post 710, and the first liquid outlet channel 240, that the material is ejected from the pressing head 100; when the pressing head 100 automatically bounces under the action of the elastic member 600, the pressing head 100 drives the upright post 200 to move upward together, due to the hysteresis effect of the piston 700 (when the upright post 200 starts to move, the piston 700 does not move, that is, when the pressing head 100 starts to move upward, the upright post 200 moves upward relative to the piston 700), the liquid storage space 320 is isolated from and not communicated with the third liquid outlet channel 210, the upright post 200 continues to move upward, and finally the piston 700 is driven to move upward together, that is, the piston 700 moves upward relative to the inner cylinder 500, the outer cylinder 300, and other parts, at this time, the liquid storage space 320 becomes larger, the valve element 400 is sucked upward and away from the liquid inlet 310, so that the liquid inlet 310 is opened, and the material in the bottle 1000 is sucked into the liquid storage space 320 through the liquid inlet 310.

It should be understood that, in the present invention, a tubular, columnar, or tubular component or a part of the component, if not specifically stated (such as the suck-back column 710), has an internal channel (or an internal cavity) with an upper end and a lower end open (connected to the outside). It should be understood that "inner" and "outer" in the present invention are substantially cylindrical and columnar and connected to each other, so that the center is the axial line of the column 200 (which may be other components such as the inner cylinder 500, the outer cylinder 300, and the outer cover 800) of the pressing pump; the direction pointing to the center is an inward direction, and one side facing the center is an inner side; the direction deviating from the center is the outward direction, and the side back to the center is the outer side. It should be understood that in the description of the present invention, "forward rotation (forward rotation)", "reverse rotation (reverse rotation)" merely indicate that the rotation directions of the two components (or in both cases) are opposite, and in practice, the forward rotation may be counterclockwise rotation, or may be clockwise rotation, and the reverse rotation may be the same.

Referring to fig. 2, 6, 8 and 9, in some embodiments of the present invention, the inner side wall of the outer cylinder 300 is provided with a ratchet ring gear 330, the outer side wall of the inner cylinder 500 is provided with a pawl projection 550, the pawl projection 550 abuts against the ratchet ring gear 330, the ratchet ring gear 330 is used for blocking the reverse rotation of the pawl projection 550, and the ratchet ring gear 330 (the ratchet teeth thereon) cannot block the forward rotation of the pawl projection 550.

When the pressing head 100 is rotated forward, the pressing head 100 drives the upright post 200 to rotate forward, finally the sliding convex strip 220 abuts against one side of the anti-rotation protrusion 540, the pressing head 100 is rotated forward continuously, the upright post 200 can drive the inner cylinder 500 to rotate forward, at this time, the ratchet ring 330 (ratchet) cannot block the pawl protrusion 550 to rotate forward continuously, namely, the inner cylinder 500 can rotate relative to the outer cylinder 300, namely, the rotation angle position of the pressing head 100 is adjustable, and the conditions of use, transportation, sales and the like are facilitated, for example, the convex nozzle (the nozzle part 110) of the pressing head 100 faces to be parallel (or coplanar) with the flat surface of the bottle body 1000, the occupied space of the whole container is reduced, the transportation and the storage are facilitated, and when the product is sold, the position of the convex nozzle of the pressing head 100 is adjusted, so that the convex nozzle is perpendicular to the flat surface of the bottle body 1000, the product is more attractive and easy to sell; and when the pressing head 100 is rotated reversely, the pressing head 100 drives the upright post 200 to rotate reversely, so that the sliding convex strip 220 moves to the upper part of the sliding groove from the upper part of the anti-pressing protrusion 530, and finally the sliding convex strip 220 abuts against the other side of the anti-rotating protrusion 540 (or the other side of the anti-rotating protrusion 540 of the other group of height position locking structure), similarly, although the upright post 200 can drive the inner cylinder 500 to rotate reversely theoretically, the ratchet ring 330 can block the pawl protrusion 550 to rotate reversely, namely, the inner cylinder 500 can not rotate relative to the outer cylinder 300, namely, the pressing head 100, the upright post 200 and the like can not rotate any more, the rotation angle position of the pressing head 100 is not adjustable, at this moment, the pressing head 100 can be normally pressed, the pressing head 100 can be rotated when being pressed, and inconvenience in use is caused. Specifically, when using the container, the pressing head 100 is in the state of not auto-lock, can be pressed for a long time, and the angular position of pressing head 100 also generally can be fixed at a specific angle (or position) by the user, presses out liquid very convenient to use when this angle, and the user generally does not want the position of pressing head 100 to change at will, so pressing head 100 can not rotate when pressing, accords with user's user demand.

When the pressing head 100 is self-locked and can not be pressed, the pressing head 100 can be rotated to adjust the angle position of the pressing head 100 without affecting the self-locking function of the pressing head 100 (namely, the self-locking position of the pressing head 100 is not required to be fixed at a specific position relative to the bottle body 1000, but can be adjusted, thereby being convenient for different position requirements of various situations such as transportation, sale and the like), at the moment, the pressing head 100 can only rotate and can not slide up and down, thereby avoiding worrying about accidental discharge caused by accidental pressing of the pressing head 100 when the angle of the pressing head 100 is adjusted; when the pressing head 100 can be pressed, the pressing head 100 cannot be rotated randomly, the angle position of the pressing head 100 can be adjusted, namely the pressing head 100 can only slide up and down and cannot rotate at the moment, so that the phenomenon that the pressing head 100 is accidentally driven to rotate when the pump is normally used (namely, when the pump is pressed to discharge materials) after the angle is adjusted is avoided, and the adjusted angle is changed to cause inconvenience in use. On the other hand, the ratchet ring gear 330 is provided so that the pawl projection 550 is always defined between two ratchet teeth on the ratchet ring gear 330, the ratchet ring gear 330 (the outer cylinder 300) has a certain limiting function on the pawl projection 550 (the angular position of the inner cylinder 500, the column 200, and the press head 100), that is, after the angular position of the press head 100 is adjusted, the angular position of the press head 100 is not randomly changed, and the ratchet ring gear 330 is provided so that, when the angular position of the press head 100 is adjusted, a distinct hand feeling (even a click sound can be generated), a prompt function can be performed, and excessive disposable adjustment can be prevented, that is, the ratchet ring gear 330 has a similar function to the hand feeling projection.

It should be understood that more sliding grooves and feeling protrusions may be further disposed between the first feeling protrusion 520 and the pressure-proof protrusion 530; it should be further understood that the height of each sliding groove can be sequentially lowered or raised along the circumference of the column 200.

Reference is made to the above description of the piston 700. When the upright post 200 moves downward relative to the piston 700, the suck back post 710 located on the suck back pipe 240 moves upward relative to the upright post 200, that is, the sealing convex ring 712 on the suck back post 710 moves upward relative to the upright post 200, and finally, the sealing convex ring 712 is flushed out of the suck back pipe 240 and moves above the suck back pipe 240, so that the third liquid outlet channel 210 is communicated with the liquid storage space 320, that is, the material in the liquid storage space 320 can enter the suck back post 710, then enter the outer side of the suck back post 710 through the liquid outlet opening 711 of the suck back post 710, and finally enter the third liquid outlet channel 210 above the suck back pipe 240 through the gap between the outer side wall of the suck back post 710 and the inner side wall of the suck back pipe 240 (at this time, the sealing convex ring 712 is located above the suck back pipe 240, and cannot close the gap); the upright post 200 moves downwards relative to the piston 700, and finally, the pushing convex portion 250 of the upright post 200 abuts against the lower limit portion 730 of the piston 700, and the upright post 200 pushes the piston 700 to move downwards together, so that the liquid storage space 320 is reduced, and the material in the liquid storage space 320 enters the third liquid outlet channel 210 and finally flows out to the outside. When the upright post 200 moves upward relative to the piston 700, the suck back post 710 moves downward relative to the upright post 200, that is, the sealing convex ring 712 on the suck back post 710 moves downward relative to the upright post 200, and finally, the sealing convex ring 712 returns to the suck back pipe 240, the sealing convex ring 712 abuts against the inner side wall of the suck back pipe 240, and the gap between the outer side wall of the suck back post 710 and the inner side wall of the suck back pipe 240 is closed, so that the liquid storage space 320 is not communicated with the third liquid outlet channel 210 above the suck back post 710; the upright post 200 moves upward relative to the piston 700, that is, the sealing convex ring 712 moves downward relative to the suck back pipe 240, so that the overall space of the third liquid outlet channel 210 above the suck back post 710 is enlarged, and a suck back effect is generated; the upright post 200 moves upwards relative to the piston 700, and finally, the pushing convex part 250 of the upright post 200 abuts against the upper limit part 720 of the piston 700, the upright post 200 pushes the piston 700 to move upwards together, so that the liquid storage space 320 is enlarged, and the object in the bottle 1000 enters the liquid storage space 320 through the liquid inlet 310. After the pressing head 100 is pressed, the pressing head 100 is released, at this time, the pressing head 100 automatically moves upwards under the action of the elastic member 600, and referring to the hysteresis effect of the piston 700, when the pressing head 100 just starts to move upwards, the piston 700 does not move, that is, the pressing head 100 (the upright post 200) moves upwards relative to the piston 700, so that a suck-back effect can be generated at this time, that is, the excess material near the discharge port of the nozzle part 110 of the pressing head 100 can be sucked back into the pressing head 100 and the upright post 200, and the excess material near the discharge port of the nozzle part 110 of the pressing head 100 is prevented from accumulating and dropping, that is, the environment is prevented from being polluted, and the material is wasted. It should be understood that the shaft 200 moves downward relative to the piston 700, i.e., the piston 700 moves upward relative to the shaft 200; the upright post 200 moves upwards relative to the piston 700, namely the piston 700 moves downwards relative to the upright post 200; other relative movements are the same. It should be understood that the suction pipe 240 inside the upright column 200 may be an additional structure as in the present embodiment, or may be a structure of the upright column 200 itself, that is, the upright column 200 is divided into at least three sections, and the diameter of the middle section of the pipe is smaller than that of the upper and lower sections of the pipe. It should be understood that the upper limit portion 720 and the lower limit portion 730 are separated by a predetermined distance, and the specific size of the predetermined distance needs to be set according to actual situations; the predetermined distance is set to facilitate the generation of the hysteresis effect of the piston 700. The structure generating the suck-back effect in this embodiment is the structure on the piston 700 and the pillar 200, so that additional parts do not need to be added, the number of parts is reduced, and the assembly difficulty and the precision requirement are reduced.

Referring to fig. 3, 4 and 10, in some embodiments of the present invention, a first air gap 910 is formed between the outer sidewall of the column 200 and the inner sidewall of the inner cylinder 500, a second air gap 920 is formed between the outer sidewall of the inner cylinder 500 and the inner sidewall of the outer cylinder 300, the sidewall of the outer cylinder 300 is provided with a vent hole 340, the upper end of the second air gap 920 is communicated with one end of the vent hole 340, and the other end of the vent hole 340 is communicated with the outside (the inner space of the bottle 1000).

It should be understood that the other end of the vent hole 340 of the push pump is connected to the outside, but the other end of the vent hole 340 is connected to the inner space of the bottle body 1000 when the push pump is assembled to the container bottle body 1000. The first ventilation gap 910, the second ventilation gap 920 and the ventilation hole 340 constitute an air passage of the pressing pump, and when the pressing pump is assembled to the container bottle 1000, external air can enter the bottle 1000 through the air passage, thereby balancing the air pressure inside and outside the bottle 1000; specifically, when the pressing head 100 moves upward and returns to its original position, the liquid storage space 320 is expanded, so that the air pressure in the liquid storage space 320 is reduced, and the air pressure in the bottle 1000 is the same as or equal to the external pressure, so that the air pressure in the bottle 1000 is higher than the air pressure in the liquid storage space 320, so that the material in the bottle 1000 is pressed into the liquid storage space 320 under the action of the air pressure, so that the air pressure in the liquid storage space 320 is increased again and finally the air pressure is the same as the external pressure, and during this period (the material in the bottle 1000 continuously enters the liquid storage space 320, the material in the bottle 1000 continuously decreases), the external air continuously enters the bottle 1000 through the air passage, thereby supplementing the vacancy caused by the reduction of the material in the bottle 1000, so that the air pressure in the bottle 1000 is always the same as the external pressure, i.e., always providing a driving force for the material in the bottle 1000 to enter the liquid storage space 320, and preventing the bottle 1000 from being flattened by the external air. It should be understood that the vent hole 340 is located at the upper end of the second vent gap 920, that is, the vent hole 340 is located at the upper end of the outer cylinder 300, and when the pressing pump is mounted on the bottle 1000, the material in the bottle 1000 is located below the vent hole 340, preventing the material from flowing out through the vent hole 340.

Referring to fig. 3, in some embodiments of the present invention, when the piston 700 moves to the upper end of the outer cylinder 300, the piston 700 closes the lower end of the second vent gap 920.

When the piston 700 moves to the upper end of the outer cylinder 300, that is, when the pressing head 100 is reset, or when the pressing pump is in an unused state and the pressing head 100 is in the most common state, the piston 700 seals the lower end of the second air gap 920, thereby effectively preventing the external air from influencing the environment inside the bottle 1000 along the air passage, and causing the problems of material dilution, pollution, deterioration and the like. Specifically, the outer sidewall of the piston 700 is inserted between the outer sidewall of the inner cylinder 500 (the mounting sleeve 580) and the inner sidewall of the outer cylinder 300, thereby closing the lower end of the second air gap 920.

Due to the air passage, external liquid may enter the bottle 1000 through the air passage, thereby diluting and even contaminating the material in the bottle 1000. The waterproof ring 570 and the water retaining ring 130 are arranged, the water retaining ring 130 can prevent outside liquid from entering the first ventilation gap 910 from the upper part of the waterproof ring 570 as much as possible, and the waterproof ring 570 can prevent liquid lower than the waterproof ring 570 from entering the first ventilation gap 910; the height of the top surface of the waterproof ring 570 is higher than that of the top surface of the mounting sleeve 580, so that even if liquid is accumulated outside the waterproof ring 570, the accumulated liquid is higher than that of the top surface of the mounting sleeve 580, and the accumulated liquid overflows from the top surface of the mounting sleeve 580 and overflows to the outside, so that the liquid accumulated outside the waterproof ring 570 cannot reach the height of the top surface of the waterproof ring 570, and the liquid enters the first ventilation gap 910. So above-mentioned setting can prevent effectively that external liquid from passing through the air flue and entering into in the bottle 1000, prevents that external liquid from diluting and polluting the material in the bottle 1000 even. The mounting sleeve 580 is mainly used for connecting the outer tub 300, and the waterproof ring 570 is used for slidably connecting the pillar 200 in addition to waterproofing.
