"Bolt connection" and "screw connection" can be replaced. For those skilled in the art, the specific meaning of the above terms in the present application can be understood in combination with the specific circumstances.

[0049] It should be understood that the similar features in the present application are only distinguished by different prefixes, so in the present application, the feature name without distinguishing prefix (or the feature name with part of the prefix) is used to represent the comprehensive of similar features of this kind.

[0050] Referring to Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 , the press pump according to the embodiment of the present application comprises a press head 100, a stand 200, an outer cylinder 300, a valve 400, an inner cylinder 500, an elastic member 600 and a piston 700.

[0051] 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 (liquid outlet) of the first liquid outlet channel 111 is connected to the outside. The other end of the first liquid outlet channel 111 is connected to the upper end of the second liquid outlet channel 121. It should be understood that the connecting part 120 is generally columnar. Referring to a common pressing pump, the spraying head part 110 is generally protruding relative to the connecting part 120. In order to facilitate transportation, storage and use, the pressing head 100 on the pressing pump can generally be rotated to adjust the position (or angle, angular position) of the spraying head part 110. For example, when the pressing pump is installed on a flat bottle body 1000, the spraying head part 110 of the pressing head 100 is generally adjusted to be parallel to the flat surface of the bottle body 1000 during transportation and storage (at this time, the first liquid outlet channel 111 is parallel to the flat surface of the bottle body 1000). During use, the user generally adjusts the spraying head part 110 of the pressing head 100 to be generally perpendicular to the flat surface of the bottle body 1000 (at this time, the first liquid outlet channel 111 is generally perpendicular to the flat surface of the bottle body 1000), which is convenient for use.

[0052] The column 200 is connected to the lower end of the connecting part 120. The column 200 is provided with a third liquid outlet channel 210. The upper end of the third liquid outlet channel 210 is connected to the lower end of the second liquid outlet channel 121. The pressing head 100 can drive the column 200 to rotate. It should be understood that the outer side wall of the upper end of the column 200 is provided with a same-rotation insertion groove 230. The inner side wall of the connecting part 120 (pressing head 100) is provided with a same-rotation insertion strip 122. The same-rotation insertion strip 122 is inserted into the same-rotation insertion groove 230. The same-rotation insertion strip 122 and the same-rotation insertion groove 230 are in interference fit, which can fix the pressing head 100 and the column 200 together after being connected. It should be understood that the connection between the column 200 and the pressing head 100 can be detachable connection as in the embodiment, or other connection modes such as bonding, hot melting connection, integral connection (i.e., the column 200 can be part of the pressing head 100), etc.

[0053] The outer cylinder 300 is provided with a liquid inlet 310 at the lower end. The outer cylinder 300 is used to be connected in the bottle body 1000. The outer cylinder 300 is a basic carrier for installing and fixing other parts of the pressing pump on the bottle body 1000. At the same time, the outer cylinder 300 separates a part of the space inside the bottle body 1000, so as to facilitate the formation of a relatively independent liquid storage space 320.

[0054] Valve 400, valve 400 is located in the outer cylinder 300, valve 400 is arranged in the lower end of the outer cylinder 300, valve 400 is used for closing the liquid inlet 310. Valve 400 is used for automatically closing the liquid inlet 310 at the lower end of the liquid storage space 320 when pressing the discharge; while moving (or rebound, return, reset) on the pressing head 100, the valve 400 automatically leaves the liquid inlet 310, thereby opening the liquid inlet 310. It should be understood that the specific form of valve 400 is various, such as the disc-shaped valve 400 in the embodiment, and also like the common spherical valve 400. It should be understood that the valve 400 can be made of metal material, or can be made of plastic.

[0055] Inner cylinder 500, inner cylinder 500 is located in the outer cylinder 300, inner cylinder 500 is arranged in the upper end of the outer cylinder 300, the column 200 is inserted in the inner cylinder 500, the column 200 can move up and down relative to the inner cylinder 500. The inner cylinder 500 is arranged, on the one hand, to facilitate the closure of the upper end of the space inside the outer cylinder 300, to play a certain sealing role for the liquid storage space 320, to minimize the direct contact of the external environment with the liquid storage space 320, pollution, and to facilitate assembly by additionally arranging the inner cylinder 500; on the other hand, the inner cylinder 500 is also the basic carrier of the up and down sliding and rotating of the column 200, that is, the outer side wall of the inner cylinder 500 is connected with the outer cylinder 300, and the inner side wall of the inner cylinder 500 is connected with the column 200.

[0056] The outer side wall of the stand column 200 is provided with a sliding convex strip 220, and the inner side wall of the inner cylinder 500 (waterproof ring 570) is sequentially provided with a first sliding groove 510, a first hand feeling convex 520, a pressure preventing convex 530 and a rotation preventing convex 540 in the forward rotation direction (or the first circumferential direction) of the inner cylinder 500, that is, the second circumferential direction opposite to the first circumferential direction. The first sliding groove 510 is used for sliding the sliding convex strip 220 up and down, the first hand feeling convex 520 is used for abutting against the outer surface of the sliding convex strip 220, the pressure preventing convex 530 is used for abutting against the bottom surface of the sliding convex strip 220 to prevent the sliding convex strip 220 from sliding downward, and the rotation preventing convex 540 is used for abutting against the side surface of the sliding convex strip 220 to prevent the sliding convex strip 220 from continuing to rotate relative to the inner cylinder 500. When the pressing head 100 is rotated, the pressing head 100 drives the stand column 200 to rotate; when the pressing head 100 is reversely rotated, the pressing head 100 drives the stand column 200 to reversely rotate, so that the sliding convex strip 220 moves from above the pressure preventing convex 530 to above the sliding groove, at this time, the pressure preventing convex 530 can slide up and down along the sliding groove, so the pressing head 100 can be pressed to drive the stand column 200 and the piston 700 to move downward, and normal liquid discharge and material discharge can be realized; when the pressing head 100 is forwardly rotated, the pressing head 100 drives the stand column 200 to forwardly rotate, so that the sliding convex strip 220 moves from above the sliding groove to above the pressure preventing convex 530, and the pressing head 100 cannot move downward, that is, the pressing head 100 cannot be pressed. When the sliding convex strip 220 of the stand column 200 is located above the pressure preventing convex 530, the sliding convex strip 220 cannot move downward, that is, the stand column 200 and the pressing head 100 cannot move downward, and the pressing head 100 cannot be pressed, so accidental pressing of the liquid discharge caused by accidental touch and the like can be prevented, and transportation, storage and daily use are facilitated; and when the height position of the pressing head 100 is locked (that is, when the pressing head 100 cannot be pressed to discharge material, or when the pressing head 100 is self-locked), the pressing head 100 only needs to be rotated, and does not need to be pressed or moved downward in other ways, so that the material is not wasted during the locking process. Further, a hand feeling convex is arranged between the sliding groove and the pressure preventing convex 530 (or other sliding grooves), which has the functions of limiting, prompting and increasing the hand feeling; that is, when the self-locking and non-self-locking states of the pressing head 100 are switched (or when the discharge gears are switched), when the sliding convex strip 220 passes the hand feeling convex, there is a certain resistance, so the hand feeling convex has a certain limiting function, and the self-locking and non-self-locking states of the pressing head 100 cannot be randomly switched when the pressing head 100 is not manually rotated; and when the sliding convex strip 220 passes the hand feeling convex, there is a clear hand feeling (even a click sound), which can clearly prompt the user that the state of the pressing head 100 has been switched.It needs to be understood that, with one first sliding groove 510, one first hand feeling convex 520 (some embodiments also include a second sliding groove, a second hand feeling convex, or more sliding grooves, hand feeling convexes), one anti-pressing convex 530 and one anti-rotation convex 540 as a group of height position locking structures, along the circumference of the inner cylinder 500, on the entire inner side wall of the inner cylinder 500, more groups of height position locking structures can also be sequentially arranged, "sequentially", that is, the anti-rotation convex 540 of the previous group of height position locking structures is followed by the first sliding groove 510 of the next group of height position locking structures; and if a head-to-tail structure is formed, the anti-rotation convex 540 of the last group of height position locking structures is followed by the first sliding groove 510 of the first group of height position locking structures; correspondingly, for each group of height position locking structures, a sliding convex strip 220 is correspondingly arranged on the stand column 200. The anti-rotation convex 540 is arranged to prevent the sliding convex strip 220 from continuing to rotate relative to the inner cylinder 500 after being rotated into the sliding groove or on the anti-pressing convex 530; at the same time, in some embodiments, the outer cylinder 300 has no special limitation on the inner cylinder 500, and the inner cylinder 500 can rotate relative to the outer cylinder 300, so the pressing head 100 can be rotated, and after the sliding convex strip 220 abuts against the anti-rotation convex 540, the pressing head 100 is continuously rotated, so that the stand column 200 drives the inner cylinder 500 to rotate relative to the outer cylinder 300, thereby changing the angular position of the pressing head 100, facilitating use.

[0057] The elastic member 600 abuts against the connecting portion 120 or the stand column 200 at one end, and abuts against the inner cylinder 500 at the other end. The elastic member 600 is used to move the pressing head 100 away from the inner cylinder 500. The elastic member 600 can be a spring, an elastic sheet, an elastic plastic member, etc., and in this embodiment, the elastic member 600 is a spring-like structure member made of plastic; specifically, the elastic member 600 is made of elastic material, and the upper and lower connecting structures of the elastic member 600 are obliquely extended structures, which are not the same as the upper and lower directions (i.e. the direction of the pressing force of the pressing head 100, the direction of the movement of the pressing head 100), facilitating the generation of deformation of the elastic member 600.

[0058] The piston 700 is arranged in the outer cylinder 300, the column 200 is connected to the piston 700 and can drive the piston 700 to move up and down, the piston 700 is located between the inner cylinder 500 and the valve 400, and a space between the piston 700 and the valve 400 is the liquid storage space 320. Alternatively, the piston 700, the valve 400 and the outer cylinder 300 jointly define the liquid storage space 320, and the liquid storage space 320 can be communicated 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; and the inner side of the piston 700 is generally connected to the column 200, and the column 200 has a certain movement space relative to the piston 700 (or the piston 700 relative to the column 200), but when the moving degree of the column 200 relative to the piston 700 is large, the column 200 can drive the piston 700 to move. The inner space of the outer cylinder 300 is divided into a liquid storage space 320 by the piston 700 and the valve 400. It should be understood that the column 200 can drive the piston 700 to move up and down, so as to change the size of the liquid storage space 320; at the same time, in the moving process of the column 200, the piston 700 has a certain hysteresis relative to the column 200, that is, the column 200 can first move a certain distance relative to the piston 700 (at this time, the piston 700 does not move, that is, at this time, the column 200 will not drive the piston 700 to move up and down), and then drive the piston 700 to move; and when the column 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 embodiment, when the column 200 moves downward relative to the piston 700, the third liquid outlet channel 210 and the liquid storage space 320 are communicated, and when the column 200 moves upward relative to the piston 700, the third liquid outlet channel 210 and the liquid storage space 320 are not communicated.More specifically, when the pressing head 100 is pressed, the pressing head 100 drives the stand column 200 to move downward, due to the hysteresis effect of the piston 700 (when the stand column 200 just starts to move, the piston 700 does not move, i.e. when the pressing head 100 just starts to move downward, the stand column 200 moves downward relative to the piston 700), the liquid storage space 320 is communicated with the third liquid outlet channel 210, the stand column 200 continues to move downward, and finally drives the piston 700 to move downward, i.e. the piston 700 moves downward relative to the inner cylinder 500, the outer cylinder 300, the bottle body 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, thereby closing the liquid inlet 310, and thus 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 back-suction column 710, and then enters the inner cavity of the lower end of the stand column 200 from the liquid outlet opening 711 of the back-suction column 710, and then enters the third channel of the stand column 200 from the gap between the back-suction column 710 and the back-suction pipe 240), and then enters the outside world in sequence through the third channel, the second channel and the first channel, i.e. the material is sprayed out from the nozzle part 110 of the pressing head 100; when the pressing head 100 is automatically popped up under the action of the elastic member 600, the pressing head 100 drives the stand column 200 to move upward, due to the hysteresis effect of the piston 700 (when the stand column 200 just starts to move, the piston 700 does not move, i.e. when the pressing head 100 just starts to move upward, the stand column 200 moves upward relative to the piston 700), the liquid storage space 320 is isolated from the third liquid outlet channel 210 and is not communicated with the third liquid outlet channel 210, the stand column 200 continues to move upward, and finally drives the piston 700 to move upward, i.e. 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 400 is sucked upward and away from the liquid inlet 310, thereby opening the liquid inlet 310, and thus the material in the bottle body 1000 is sucked into the liquid storage space 320 through the liquid inlet 310.

[0059] It should be understood that, in the present application, the parts or parts in certain positions, such as the back-suction column 710, which are cylindrical, columnar or tubular, have internal channels (or inner cavities) with both ends open (communicated with the outside world) unless otherwise specified. It should be understood that, in the present application, "in" and "out" are centered on the axis of the stand column 200 (or the inner cylinder 500, the outer cylinder 300, the outer cover 800 and other parts) of the pressing pump, which is roughly cylindrical or columnar and connected to each other; the direction pointing to the center is the inward direction, and the side facing the center is the inner side; the direction away from the center is the outward direction, and the side away from the center is the outer side. It should be understood that, in the description of the present application, "forward rotation (forward rotation)" and "reverse rotation (reverse rotation)" only indicate that the rotation directions of two parts (or two situations) are opposite, but in practice, the forward rotation can be counterclockwise rotation or clockwise rotation, and the reverse rotation is the same.

[0060] Referring to Figure 2 , Figure 6 , Figure 8 and Figure 9 , in some embodiments of the present application, the inner side wall of the outer cylinder 300 is provided with a ratchet ring 330, the outer side wall of the inner cylinder 500 is provided with a pawl protrusion 550, the pawl protrusion 550 abuts against the ratchet ring 330, the ratchet ring 330 is used to block the reverse rotation of the pawl protrusion 550, and the ratchet ring 330 (ratchet) cannot block the forward rotation of the pawl protrusion 550.

[0061] When the pressing head 100 is rotated forward, the pressing head 100 drives the upright column 200 to rotate forward, and finally makes the sliding protrusion 220 abut against one side of the anti-rotation protrusion 540. When the pressing head 100 is continuously rotated forward, the upright column 200 drives the inner cylinder 500 to rotate forward, at this time the ratchet ring 330 (ratchet) cannot block the pawl protrusion 550 from continuing to rotate forward, that is, the inner cylinder 500 can rotate relative to the outer cylinder 300, that is, the angle position of the pressing head 100 can be adjusted, which is convenient for use, transportation, sales, etc. For example, the protruding mouth (spray head part 110) of the pressing head 100 is parallel (or coplanar) to the flat surface of the bottle body 1000, the occupied space of the container as a whole is reduced, and transportation and storage are facilitated. When selling, the position of the protruding mouth of the pressing head 100 is adjusted so that the protruding mouth is perpendicular to the flat surface of the bottle body 1000, the product is more beautiful, and is easy to sell. When the pressing head 100 is rotated reversely, the pressing head 100 drives the upright column 200 to rotate reversely, so that the sliding protrusion 220 moves from above the anti-pressing protrusion 530 to above the sliding groove, and finally makes the sliding protrusion 220 abut against the other side of the anti-rotation protrusion 540 (or the other side of the anti-rotation protrusion 540 of the other set of height position locking structure). Similarly, although the upright column 200 can theoretically drive the inner cylinder 500 to rotate reversely, at this time the ratchet ring 330 blocks the pawl protrusion 550 from rotating reversely, that is, the inner cylinder 500 cannot rotate relative to the outer cylinder 300, that is, the pressing head 100, the upright column 200, etc. cannot be rotated any more, and the angle position of the pressing head 100 cannot be adjusted. At this time, the pressing head 100 can be normally pressed, which prevents the pressing head 100 from being rotated during pressing, causing inconvenience in use. Specifically, when using the container, the pressing head 100 is in a state of not self-locking and can be pressed for a long time. The angle position of the pressing head 100 is generally fixed at a specific angle (or position) by the user. At this angle, it is very convenient to press out liquid, and the user generally does not want the position of the pressing head 100 to change randomly. Therefore, the pressing head 100 will not rotate during pressing, which meets the use demand of the user.

[0062] When the pressing head 100 is self-locked and cannot be pressed, the pressing head 100 can be rotated to adjust the angular position of the pressing head 100 without affecting the self-locking function of the pressing head 100 (i.e., the self-locking position of the pressing head 100 does not need to be fixed at a specific position, but can be adjusted to meet different position requirements in various situations such as transportation and sales), at this time the pressing head 100 can only be rotated and cannot slide up and down, so there is no need to worry about accidental pressing of the pressing head 100 when adjusting the angle of the pressing head 100, causing accidental dispensing; when the pressing head 100 can be pressed, the pressing head 100 cannot be arbitrarily rotated or the angular position of the pressing head 100 adjusted, i.e., at this time the pressing head 100 can only slide up and down and cannot be rotated, preventing the adjusted angle from changing when the pressing pump is normally used (i.e., when the material is pressed out), and accidentally rotating the pressing head 100, causing the adjusted angle to change and making it inconvenient to use. On the other hand, the ratchet ring 330 is provided to limit the pawl protrusion 550 between two ratchet teeth on the ratchet ring 330 at all times, and the ratchet ring 330 (outer cylinder 300) has a certain limiting effect on the pawl protrusion 550 (inner cylinder 500, stand 200, and angular position of the pressing head 100), i.e., the angular position of the pressing head 100 will not change arbitrarily after the angular position of the pressing head 100 is adjusted, and the ratchet ring 330 is provided to have a clear hand feel (even a clicking sound) when adjusting the angular position of the pressing head 100, which can serve as a prompt and prevent excessive adjustment at one time, i.e., the ratchet ring 330 has the similar effect of the hand feel protrusion.

[0063] Referring to Figure 5 and Figure 7 In some embodiments of the present application, along the forward rotation direction of the inner cylinder 500, the inner side wall of the inner cylinder 500 is sequentially provided with a first sliding groove 510, a first hand feel protrusion 520, a second sliding groove, a second hand feel protrusion, a pressure preventing protrusion 530, and a rotation preventing protrusion 540, and the bottom surfaces of the first sliding groove 510 and the second sliding groove are not of the same height.

[0064] The provision of multiple hand feel protrusions all having the same limiting and hand feel prompting effects, and the provision of multiple sliding grooves with different bottom surface heights, can make the pressing pump have multiple dispensing gears, i.e., when the pressing head 100 is in different sliding grooves at the sliding protrusion 220, the pressing head 100 can move downward by different distances, so that the amount of material pumped out during pressing is different, and the pressing pump can be switched to different material pumping amounts for convenient actual use. It should be understood that more sliding grooves and hand feel protrusions can be provided between the first hand feel protrusion 520 and the pressure preventing protrusion 530. It should be further understood that the heights of the sliding grooves can decrease or increase sequentially along the circumference of the stand 200.

[0065] Referring to Figure 3 ,Figure 4 and Figure 11 In some embodiments of the present application, the middle part of the piston 700 is upwardly convexly provided with a back-suction column 710, the upper end of the back-suction column 710 is closed, the lower end is not closed, the side wall of the back-suction column 710 is provided with a liquid outlet opening 711 for communicating the liquid storage space 320 and the third liquid outlet channel 210, the outer side wall of the back-suction column 710 is provided with a sealing convex ring 712, the sealing convex ring 712 is located above the liquid outlet opening 711, the inside of the column 200 is provided with a back-suction pipe 240, the back-suction column 710 is inserted into the back-suction pipe 240, so that the sealing convex ring 712 abuts against the inner side wall of the back-suction pipe 240, thereby isolating the liquid storage space 320 and the third liquid outlet channel 210, the side wall of the piston 700 is provided with an upper limiting part 720 and a lower limiting part 730, the side wall of the column 200 is provided with a pushing convex part 250, the pushing convex part 250 is located between the upper limiting part 720 and the lower limiting part 730, the upper limiting part 720 and the lower limiting part 730 are separated by a predetermined distance.

[0066] The above-mentioned piston 700 related content can be referred to. When the column 200 is lowered relative to the piston 700, the back-suction column 710 located in the back-suction pipe 240 is raised relative to the column 200, that is, the sealing convex ring 712 on the back-suction column 710 is raised relative to the column 200, and finally, the sealing convex ring 712 is ejected from the back-suction pipe 240 and moves above the back-suction pipe 240, so that the third liquid outlet channel 210 and the liquid storage space 320 are communicated, that is, the material in the liquid storage space 320 can enter the back-suction column 710, then enter the outside of the back-suction column 710 through the liquid outlet opening 711 of the back-suction column 710, and finally enter the third liquid outlet channel 210 above the back-suction pipe 240 through the gap between the outer wall of the back-suction column 710 and the inner wall of the back-suction pipe 240 (at this time, the sealing convex ring 712 is located above the back-suction pipe 240 and does not seal the gap); the column 200 continues to move downward relative to the piston 700, and finally, the pushing convex part 250 of the column 200 abuts against the lower limiting part 730 of the piston 700, so that the column 200 pushes the piston 700 to move downward together, thereby reducing the liquid storage space 320, 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 column 200 is raised relative to the piston 700, the back-suction column 710 is lowered relative to the column 200, that is, the sealing convex ring 712 on the back-suction column 710 is lowered relative to the column 200, and finally, the sealing convex ring 712 returns to the back-suction pipe 240 and abuts against the inner wall of the back-suction pipe 240 to seal the gap between the outer wall of the back-suction column 710 and the inner wall of the back-suction pipe 240, so that the liquid storage space 320 and the third liquid outlet channel 210 above the back-suction pipe 240 are no longer communicated; the column 200 continues to move upward relative to the piston 700, that is, the sealing convex ring 712 moves downward relative to the back-suction pipe 240, so that the overall space of the third liquid outlet channel 210 above the back-suction pipe 240 is expanded, thereby producing a back-suction effect; the column 200 continues to move upward relative to the piston 700, and finally, the pushing convex part 250 of the column 200 abuts against the upper limiting part 720 of the piston 700, so that the column 200 pushes the piston 700 to move upward together, thereby expanding the liquid storage space 320, and the object in the bottle body 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 is automatically raised under the action of the elastic member 600, and according to the above-mentioned hysteresis effect of the piston 700, when the pressing head 100 starts to move upward, the piston 700 does not move, that is, the pressing head 100 (the column 200) moves upward relative to the piston 700, so that at this time, the back-suction effect can be produced, that is, the material residue near the outlet of the nozzle part 110 of the pressing head 100 can be sucked back into the pressing head 100 and the column 200, thereby preventing the material residue near the outlet of the nozzle part 110 of the pressing head 100 from being accumulated and dripping, that is, polluting the environment and causing waste of material.It should be understood that the column 200 is lowered relative to the piston 700, that is, the piston 700 is raised relative to the column 200; the column 200 is raised relative to the piston 700, that is, the piston 700 is lowered relative to the column 200; and the other relative movements are the same. It should be understood that the back suction pipe 240 inside the column 200 can be an additional structure as in the present embodiment, or can be a structure of the column 200 itself, that is, the column 200 is divided into at least three sections, and the diameter of the middle section pipe is smaller than that of the upper and lower section pipes. 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 the actual situation; the predetermined distance is set to facilitate the generation of the lag effect of the piston 700. The structure for generating the back suction effect in the present embodiment is the structure on the piston 700 and the column 200, so it does not need to increase additional parts, reduces the number of parts, and thus reduces the assembly difficulty and precision requirement.

[0067] With reference to Figure 3 , Figure 4 and Figure 10 In some embodiments of the present application, a first ventilation gap 910 exists between the outer side wall of the column 200 and the inner side wall of the inner cylinder 500, a second ventilation gap 920 exists between the outer side wall of the inner cylinder 500 and the inner side wall of the outer cylinder 300, the side wall of the outer cylinder 300 is provided with a ventilation hole 340, the upper end of the second ventilation gap 920 is communicated with one end of the ventilation hole 340, and the other end of the ventilation hole 340 is communicated with the outside (the internal space of the bottle body 1000).

[0068] It should be understood that the other end of the vent hole 340 on the pressing pump is communicated with the outside, but when the pressing pump is assembled to the container bottle body 1000, the other end of the vent hole 340 is communicated with the internal space of the bottle body 1000. The first vent gap 910, the second vent gap 920 and the vent hole 340 constitute an air passage of the pressing pump, when the pressing pump is assembled to the container bottle body 1000, the outside air can enter the bottle body 1000 through the air passage, so as to balance the air pressure inside and outside the bottle body 1000. Specifically, when the pressing head 100 is reset, the liquid storage space 320 is expanded, so the air pressure in the liquid storage space 320 is reduced, and the air pressure in the bottle body 1000 is the same as and unchanged from the outside air pressure, so the air pressure in the bottle body 1000 is greater than that in the liquid storage space 320, so under the action of the air pressure, the material in the bottle body 1000 is pressed into the liquid storage space 320, so that the air pressure in the liquid storage space 320 is re-increased to be the same as the outside air pressure. During this period (the material in the bottle body 1000 continuously enters the liquid storage space 320, and the material in the bottle body 1000 is continuously reduced), the outside air continuously enters the bottle body 1000 through the air passage to make up for the vacancy caused by the reduction of the material in the bottle body 1000, so that the air pressure in the bottle body 1000 is always the same as the outside air pressure, that is, always provides driving force for the material in the bottle body 1000 to enter the liquid storage space 320, and at the same time prevents the bottle body 1000 from being deformed by the outside air pressure. 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 installed on the bottle body 1000, the material in the bottle body 1000 is located below the vent hole 340, so as to prevent the material from flowing out of the vent hole 340.

[0069] With reference to Figure 3 In some embodiments of the present application, when the piston 700 moves to the upper end of the outer cylinder 300, the piston 700 seals the lower end of the second vent gap 920.

[0070] When the piston 700 moves to the upper end of the outer cylinder 300, that is, when the pressing head 100 is reset, or in other words, when the pressing pump is in an unused state and the pressing head 100 is in the most common state, the piston 700 will seal the lower end of the second vent gap 920, thereby effectively preventing the outside air from affecting the environment inside the bottle body 1000 along the air passage, causing problems such as dilution, pollution and deterioration of the material. Specifically, the outer side wall of the piston 700 is inserted between the outer side wall of the inner cylinder 500 (the mounting sleeve 580) and the inner side wall of the outer cylinder 300, thereby sealing the lower end of the second vent gap 920.

[0071] With reference to Figure 1 , Figure 3 , Figure 7 and Figure 12In some embodiments of the present application, the pressing head 100 further comprises a water-blocking ring 130, the water-blocking ring 130 is connected to the connecting part 120, the water-blocking ring 130 surrounds the connecting part 120, the inner cylinder 500 comprises a connecting ring plate 560, a waterproof ring 570 and a mounting sleeve 580, the inner side of the connecting ring plate 560 is connected to the waterproof ring 570, the outer side of the connecting ring plate 560 is connected to the mounting sleeve 580, the top surface of the waterproof ring 570 is higher than the top surface of the mounting sleeve 580, the water-blocking ring 130 is located between the waterproof ring 570 and the mounting sleeve 580, there is a first air gap 910 between the outer side wall of the stand column 200 and the inner side wall of the waterproof ring 570, there is a second air gap 920 between the outer side wall of the mounting sleeve 580 and the inner side wall of the outer cylinder 300, the outer side wall of the mounting sleeve 580 abuts against the inner side wall of the outer cylinder 300, the stand column 200 is inserted into the waterproof ring 570, and the other end of the elastic member 600 abuts against the connecting ring plate 560.

[0072] Due to the existence of the air passage, external liquid can also enter the bottle body 1000 from the air passage, thereby diluting or even contaminating the material in the bottle body 1000. The waterproof ring 570 and the water-blocking ring 130 are arranged, the water-blocking ring 130 can prevent external liquid from entering the first air gap 910 from above the waterproof ring 570 as much as possible, and the waterproof ring 570 can prevent liquid below the height of the waterproof ring 570 from entering the first air gap 910; the top surface of the waterproof ring 570 is higher than the top surface of the mounting sleeve 580, so that even if liquid is accumulated outside the waterproof ring 570, the height of the accumulated liquid will be higher than the top surface of the mounting sleeve 580, and the accumulated liquid will overflow from the top surface of the mounting sleeve 580 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 cannot enter the first air gap 910. Therefore, the above arrangement can effectively prevent external liquid from entering the bottle body 1000 through the air passage, and prevent the external liquid from diluting or even contaminating the material in the bottle body 1000. The mounting sleeve 580 is mainly used for connecting the outer cylinder 300, and the waterproof ring 570 is used for slidingly connecting the stand column 200 in addition to waterproofing.

[0073] Referring to Figure 1 , Figure 2 and Figure 3 In some embodiments of the present application, the outer cover 800 is further provided, the middle part of the outer cover 800 is provided with a sliding column 810, the water-blocking ring 130 is inserted into the sliding column 810, and the water-blocking ring 130 can slide up and down in the sliding column 810.

[0074] The outer cover 800 is arranged, and the water blocking ring 130 is inserted into the sliding column 810, so that the outer cover 800 plays a covering and blocking role, and can maximize the blocking of external liquid into the internal space of the pressing pump below the outer cover 800. In particular, the outer cover 800 is arranged, and external liquid cannot directly fly to the top surface of the water blocking ring 570 and the inlet of the first ventilation gap 910. In cooperation with the outer cover 800 and the water blocking ring 130, the external liquid above the outer cover 800 can at most slide along the outer side wall of the water blocking ring 130 and drip to the outer side of the water blocking ring 570, and accumulate in the space between the outer side of the water blocking ring 570 and the inner side of the mounting sleeve 580, so that the waterproof effect is enhanced. It should be understood that there can be a ventilation gap between the outer side wall of the water blocking ring 570 and the inner side wall of the sliding column 810, so that external gas enters below the outer cover 800 and finally enters the air duct, and the water blocking ring 570 is also facilitated to slide (the pressing head 100 is pressed and reset). Of course, there can be no ventilation gap between the outer side wall of the water blocking ring 570 and the inner side wall of the sliding column 810, and external gas enters the air duct through other channels. It should be understood that in the container, the outer cover 800 is connected with the bottle body 1000, and in the embodiment, the outer cover 800 is threadedly connected with the bottle body 1000. It should be understood that the stand column 200 is inserted into the water blocking ring 570 of the inner cylinder 500 through the sliding column 810.

[0075] With reference to Figure 4 and Figure 6 In some embodiments of the application, the inner cylinder 500 further comprises a limiting ring 590, the inner side of the limiting ring 590 is connected with the outer side wall of the upper end of the mounting sleeve 580, the inner side wall of the sliding column 810 is provided with a blocking ring 811 and a blocking portion 812, the limiting ring 590 is located below the blocking portion 812, the limiting ring 590 is located above the blocking ring 811, and the limiting ring 590 is provided with an overflow notch 591.

[0076] The limiting ring 590 is located between the blocking ring 811 and the blocking portion 812, thereby playing a certain limiting and fixing role on the outer cover 800, so that the outer cover 800 is fixed on the inner cylinder 500 to some extent, facilitating assembly and fixation; the blocking ring 811 is arranged, facilitating the limiting ring 590 of the outer cover 800 to be arranged between the blocking ring 811 and the blocking portion 812, and the blocking ring 811 has a certain blocking effect, and the blocking effect is not too large, so that the assembly of the outer cover 800 is not hindered. The limiting ring 590 is provided with an overflow gap 591, so as to prevent the limiting ring 590 from abutting against the blocking ring 811 to form a seal, thereby causing liquid accumulated between the waterproof ring 570 and the mounting sleeve 580 to not flow out to the outside; and the limiting ring 590 is provided with the overflow gap 591, so that the seal is not formed, and the liquid accumulated between the waterproof ring 570 and the mounting sleeve 580 can flow out from the overflow gap 591 and finally reach the outside. It should be understood that, in the embodiment, the outer side of the outer cylinder 300 is provided with a flow guide groove located below the overflow gap 591; the flow guide groove is arranged, facilitating the liquid flowing out of the overflow gap 591 to continue to flow to the outside.

[0077] With reference to Figure 1 and Figure 2 In some embodiments of the present application, the pressing head 100, the stand column 200, the outer cylinder 300, the elastic member 600, the valve member 400, the inner cylinder 500 and the piston 700 are all made of the same plastic material.

[0078] Although the existing pressing pump is made of plastic, the specific plastic types of the components are different, which is not conducive to recycling. The pressing pump of the present application is made of plastic material, more specifically, made of a single material, which facilitates the unified procurement and processing of raw materials, and also facilitates the overall recycling of the pressing pump without the need for additional classification and recycling of each component of the pressing pump according to the plastic type. The plastic material is the sum of plastic material and rubber material. It should be understood that all components of the container, such as the outer cover 800 and the bottle body 1000 that the container can contain, can also be made of the same plastic material.

[0079] With reference to Figure 2 and Figure 3 In some embodiments of the present application, the pumping auxiliary assembly further comprises a suction pipe 1100, the suction pipe 1100 being located in the bottle body 1000, the upper end of the suction pipe 1100 being connected to the lowermost end of the outer cylinder 300, and the lower end of the suction pipe 1100 extending into the bottom of the bottle body 1000.

[0080] The suction pipe 1100 is arranged to facilitate the suction of the material in the bottle body 1000, especially the material at the bottom of the bottle body 1000, into the storage space 320, so as to prevent the material in the container from being reduced after the container is used for a long time, and the lowermost end of the outer cylinder 300 cannot directly suck the material any more.
