[0058] The first embodiment of the present invention proposes a push head locking structure that can lock the push head in the press pump to prevent the situation in which the push head 10 is accidentally touched during transportation and storage, causing the push head 10 to be unlocked and causing liquid to leak. The second embodiment of the present invention also proposes a press pump having the push head locking structure provided by the first embodiment above. The press pump can prevent the situation in which the push head 10 is accidentally touched and caused to be unlocked, causing liquid to leak, by locking the push head 10 with the sub-column 50. The third embodiment of the present invention also proposes a container having the push pump provided by the second embodiment above. The container can prevent the situation in which the push head 10 is accidentally touched and caused to be unlocked, causing liquid to leak, by using the push head locking structure in the press pump.

[0059] Reference Figures 1 to 3 According to the pressing pump of the second embodiment of the present invention, the pressing head locking structure applied to the pressing pump of the first embodiment of the present invention is explained below through the pressing pump, as follows: the pressing pump has an axial direction (the up and down direction as shown in the figure), and the pressing pump includes a pressing head 10, a locking cover 20, a main body 30, a main column 40 and a sub-column 50. The pressing head 10 can slide in the axial direction, and the pressing head 10 has a first liquid outlet channel 11; the lower end of the pressing head 10 is inserted into the lock cover 20, and the pressing head 10 and the lock cover 20 are sealed and connected with each other, and the lock cover 20 is threadedly connected to the container; the body 30 is arranged on the inner side of the lock cover 20, and the upper end of the body 30 is buckled on the inner side of the lock cover 20. The upper end of the body 30 can be sealed and buckled on the inner side of the lock cover 20, and the upper end of the body 30 and the inner wall of the lock cover 20 are clearance-matched. The lock cover 20 can rotate relative to the body 30, and the body 30 has a piston chamber 31. The lower end of the body 30 is provided with a first valve 32; the main column 40 can be connected to the lower end of the pressing head 10 and is located in the body 30. The main column 40 has a second liquid outlet channel 41. The first liquid outlet channel 11 is connected to the second liquid outlet channel 41, and a second valve 42 is provided in the second liquid outlet channel 41. A piston portion 43 is integrally formed on the outer side of the main column 40, and the outer side of the piston portion 43 can abut against the inner wall of the main body 30, and the piston portion 43 can slide along the axial direction in the piston cavity 31; the sub-column 50 can be fixed in the main body 30 and is located between the first valve 32 and the second valve 42. A liquid storage cavity 33 is provided between the sub-column 50 and the piston portion 43, and the liquid storage cavity 33 is used to connect the first valve 32 and the second valve 42. The lower end of the main column 40 and the upper end of the sub-column 50 are detachably connected, and the pressing head 10 is locked with the sub-column 50 through the main column 40, and the main column 40 and the sub-column 50 are sealed.

[0060] Specifically, the press pump of the present invention mainly includes a press head 10, a locking cover 20, a main body 30, a main column 40 and a secondary column 50. The press head 10 is designed to be able to slide along the axial direction of the press pump. While sliding along the axial direction, the connection between the lower end of the press head 10 and the locking cover 20 should also maintain sealing. This design allows the user to start and stop the pump by pressing the press head 10, and also ensures that the piston chamber 31 has a good air pressure, thereby preventing the piston chamber 31 from leaking during transportation and storage. A first liquid outlet channel 11 is provided on the press head 10 for the output of liquid. The locking cover 20 is arranged at the lower end of the press head 10, and the press head 10 is inserted into the locking cover 20. The inner side of the locking cover 20 may be provided with a first locking screw 21, which allows the locking cover 20 to be threadedly connected to the container, thereby achieving a tight connection between the pump and the container. It should be noted that the first locking screw 21 and the locking cover 20 can be integrally formed or assembled as a single unit. The locking cover 20 assembled with the first locking screw 21 can be threadedly connected to the container via the first locking screw 21. The main body 30 is disposed on the inner side of the locking cover 20, with its upper end buckled onto the inner side of the locking cover 20, with a clearance fit between the two. This design allows the locking cover 20 to rotate relative to the main body 30, and when the locking cover 20 is tightened onto the container, it does not affect the stability of the main body 30 and the pressing head 10. The main body 30 is provided with a piston cavity 31 within it for receiving the piston portion 43. The lower end of the main body 30 is also provided with a first valve 32 for controlling the flow of liquid. The main column 40 can be connected to the lower end of the pressing head 10 and is located within the main body 30. A second liquid outlet channel 41 is provided inside the main column 40, and the channel is connected to the first liquid outlet channel 11 of the pressing head 10, thereby forming a complete liquid outlet path. A second valve 42 is also provided in the second liquid outlet channel 41 for further controlling the flow of liquid. A piston portion 43 is integrally formed on the outer side of the main column 40. The outer side of the piston portion 43 can be tightly abutted against the inner wall of the main body 30 and can slide in the axial direction in the piston cavity 31. When the user presses the pressing head 10, the piston portion 43 will move accordingly, thereby changing the volume of the liquid storage cavity 33 and realizing the extraction and discharge of liquid. The sub-column 50 is fixed in the main body 30 and is located between the first valve 32 and the second valve 42. A liquid storage cavity 33 is formed between the sub-column 50 and the piston portion 43. The liquid storage cavity 33 is connected to the first valve 32 and the second valve 42, and serves to temporarily store liquid. The upper ends of the main column 40 and the secondary column 50 are detachably connected and locked. This design allows the pressing head 10 to be secured during transportation and storage, while the main column 40 and secondary column 50 can be separated during use, facilitating the use of the pressing head 10 and ensuring the stability and reliability of the entire pressing pump. Furthermore, the detachable connection of the pressing head 10 through the main column 40 and secondary column 50 facilitates replacement and maintenance.

[0061] During use, the user only needs to gently separate the main column 40 and the secondary column 50 to unlock the push head 10. Gently driving the push head 10 can start the pressing pump. As the push head 10 moves down or up, the piston part 43 will also move accordingly, thereby changing the pressure in the liquid storage chamber 33. When the push head 10 is driven downward and the pressure in the liquid storage chamber 33 increases, the first valve 32 will close and the second valve 42 will open, allowing the liquid in the liquid storage chamber 33 to flow into the second liquid outlet channel 41. The liquid entering the second liquid outlet channel 41 can be discharged through the first liquid outlet channel 11 for use by the user; at the same time, the first valve 32 will close to prevent the liquid from flowing back from the liquid storage chamber 33 into the container. On the contrary, when the user drives the pressing head 10 to move upward, the piston part 43 will move upward, and the pressure in the liquid storage chamber 33 will decrease. At this time, the second valve 42 is closed and the first valve 32 is opened. The liquid in the container is drawn into the liquid storage chamber 33 by the negative pressure in the liquid storage chamber 33, and is used to be discharged from the first liquid outlet channel 11 and the second liquid outlet channel 41 when the pressing head 10 is pressed next time.

[0062] Therefore, it can be understood that the pressing pump according to the embodiment of the second aspect of the present invention has at least the following beneficial effects: the secondary column 50 is fixed in the main body 30, and the pressing head 10 can be locked with the secondary column 50 through the detachable connection between the main column 40 and the secondary column 50, and then the pressing head 10 can be fixed in the main body 30, which can prevent the pressing head 10 from moving relative to the main body 30; and the relatively static pressing head 10 and the main body 30 can prevent accidental discharge of materials due to accidental touching of the pressing head 10 during transportation, storage, etc. of the container. In addition, it can be understood that the pressing pump of the present invention mainly includes the pressing head 10, the locking cover 20, the main body 30, the main column 40 and the secondary column 50, so the pressing pump provided by the present invention has a relatively simple structure, which is simplified from the existing multiple plastic parts to the fewer plastic parts of the present invention, which simplifies the structure, facilitates assembly, and reduces production costs.

[0063] Further, refer to Figures 3 and 4 as well as Figures 10 to 12 In some embodiments of the present invention, an elastic member 44 is sleeved on the outer side of the lower end of the main column 40, and the elastic member 44 is located in the liquid storage chamber 33. The lower end of the elastic member 44 abuts against the secondary column 50, and the upper end of the elastic member 44 abuts against the inner lower end of the piston part 43.

[0064] The present invention further provides an elastic member 44 on the outer side of the lower end of the main column 40. This design is intended to enhance the recovery performance and stability of the press pump, while ensuring smooth liquid flow; it is also convenient for users to use. Specifically, the elastic member 44 is located in the liquid storage chamber 33, with its lower end abutting against the secondary column 50, and its upper end abutting against the inner lower end of the piston part 43. This configuration enables the elastic member 44 to play an important role in the operation of the press pump. When the user presses the button 10, the main column 40 and the piston part 43 will move downward. At this time, the elastic member 44 is compressed, and the liquid in the liquid storage chamber 33 is squeezed out of the liquid storage chamber 33, flowing through the second liquid outlet channel 41 and the first liquid outlet channel 11 for user use. When the user releases the button 10, the elastic member 44 will push the piston portion 43 and the main column 40 upward due to its own elastic restoring force, thereby returning to the initial position and preparing for the next press; at the same time, as the piston portion 43 and the main column 40 move upward, the space of the liquid storage chamber 33 increases, and the negative pressure generated can open the first valve 32, and draw the liquid in the container into the liquid storage chamber 33 to provide liquid for the next press.

[0065] It is understandable that the addition of the elastic member 44 not only improves the recovery speed of the pressing pump, but also makes the pressing process smoother, reducing the possibility of jamming and leakage. At the same time, the elastic member 44 can also absorb and buffer the impact force during the pressing process to a certain extent, protect the internal structure of the pressing pump, and extend its service life. In actual applications, the elastic member 44 can be made of materials with excellent elasticity and corrosion resistance such as rubber and silicone to ensure its long-term and stable operation. In addition, the specific shape and size of the elastic member 44 can also be customized according to the actual needs of the pressing pump to achieve the best use effect.

[0066] However, it should be emphasized that the pump provided in the embodiment of the present invention does not need to include the elastic member 44, and the user can actively drive the pressing head 10 to move up and down to still achieve the purpose of pumping liquid. Furthermore, the location of the elastic member 44 in the above embodiment is not specifically limited and can be set to be internal or external.

[0067] Reference Figures 2 to 4 as well as Figures 10 to 12 In some embodiments of the present invention, the main column 40 and the secondary column 50 are detachably connected via a threaded connection. Specifically, the secondary column 50 includes a connecting portion 51 and a clamping portion 52. The connecting portion 51 is provided with a second locking screw 511, which is threadedly connected to the lower end of the main column 40 via the second locking screw 511. The clamping portion 52 is provided at the lower end of the connecting portion 51, and the outer periphery of the clamping portion 52 is clamped into a clamping groove on the inner side wall of the body 30.

[0068] This embodiment further refines and optimizes the structure of the secondary column 50. Specifically, the secondary column 50 includes a connecting portion 51 and a clamping portion 52. The design of these two parts enables the secondary column 50 to be more firmly connected to the main column 40 and the main body 30, thereby improving the overall stability and durability of the pump. The connecting portion 51 is the upper structure of the secondary column 50 and is characterized by the provision of a second locking screw 511. The second locking screw 511 is threadedly connected to the lower end of the main column 40, ensuring a tight fit between the secondary column 50 and the main column 40. By rotating the button 10 to drive the main column 40 to rotate, the secondary column 50 can be easily connected or disconnected from the main column 40, which not only simplifies the installation and maintenance process; at the same time, when the button 10 is rotated to separate the main column 40 from the secondary column 50, the elastic member 44 provided can quickly lift the main column 40 upward, making it easy for the user to unlock the button 10. The clamping portion 52 is located at the lower end of the connecting portion 51, and its outer peripheral side can be clamped into the clamping groove of the inner wall of the main body 30. This clamping method effectively prevents the secondary column 50 from loosening, shifting or rotating during use, further enhancing the structural stability of the press pump. In actual application, the user can tightly connect or separate the secondary column 50 and the main column 40 by rotating the press head 10. At the same time, the clamping portion 52 will automatically snap into the clamping groove (not marked in the figure) of the main body 30, realizing a stable connection between the secondary column 50 and the main body 30. This design not only simplifies the installation steps, but also improves the convenience and reliability of the use of the press pump.

[0069] Further, refer to Figures 4 to 8 In some embodiments of the present invention, the connecting portion 51 is sealedly connected to the lower end of the main column 40 via a sealing structure 46. Specifically, the upper end of the connecting portion 51 is hermetically engaged with the second liquid outlet channel 41 via the sealing structure 46. This engagement ensures a tight fit between the connecting portion 51 and the second liquid outlet channel 41, effectively preventing liquid leakage therefrom when the main column 40 and the secondary column 50 are locked. This not only improves the sealing performance of the compression pump but also further enhances its safety and reliability.

[0070] In actual application, when the user rotates the button 10 to drive the main column 40 to rotate, the thread of the connecting portion 51 will be separated from the thread of the main column 40, so that the sealing structure 46 between the main column 40 and the connecting portion 51 will be disengaged from each other, thereby achieving the unlocking of the button 10. In addition, when the main column 40 and the secondary column 50 are locked, the upper end of the connecting portion 51 is tightly inserted into the second liquid outlet channel 41 of the main column 40, forming an effective sealing barrier. This design not only simplifies the installation process, but also enables the pressing pump to maintain good sealing and stability during long-term use. The sealing structure 46 can be a clamping structure of the convex part and the concave part, or it can be a sealing rubber ring, gasket, etc., which is not specifically limited in the embodiment of the present utility model.

[0071] Reference Figures 2 to 4 as well as Figures 10 to 12 In some embodiments of the present invention, an external thread is provided on the outer side of the connecting portion 51, and an internal thread is provided on the lower end of the main column 40. The connecting portion 51 and the main column 40 are threadedly connected, and the upper end of the connecting portion 51 is sealed and clamped in the second liquid outlet channel 41.

[0072] Specifically, the present invention has carried out detailed design and optimization of the connection method between the connecting part 51 and the main column 40. As a part of the secondary column 50, the connection stability and sealing between the connecting part 51 and the main column 40 are crucial to the performance of the entire pressing pump. Specifically, the outer side of the connecting part 51 is provided with an external thread, and the lower end of the main column 40 is provided with an internal thread matching it. This threaded connection method is not only simple and easy, but also can provide a stable connection. The user only needs to rotate the button 10 to drive the main column 40 to rotate, thereby achieving separation or locking between the connecting part 51 and the main column 40.

[0073] In addition, the upper end of the connecting portion 51 is designed to be sealingly snapped into the second liquid outlet channel 41. This snap-on connection ensures a tight fit between the connecting portion 51 and the second liquid outlet channel 41, thereby effectively preventing leakage of liquid at this location when the main column 40 and the secondary column 50 are locked. This not only improves the sealing performance of the press pump, but also further enhances the safety and reliability of its use. In actual application, when the user rotates the press head 10 to drive the main column 40 to rotate, the external thread of the connecting portion 51 will separate from the internal thread of the main column 40, thereby unlocking the press head 10. In addition, when the main column 40 and the secondary column 50 are locked, the upper end of the connecting portion 51 is tightly snapped into the second liquid outlet channel 41, forming an effective sealing barrier. This design not only simplifies the installation process, but also enables the press pump to maintain good sealing and stability during long-term use.

[0074] It should be noted that, according to the above embodiment, the installation position of the sealing structure 46 and the threaded connection method between the connecting portion 51 and the lower end of the main column 40 are not specifically limited. Figures 4 to 8 , we can know that:

[0075] The connecting portion 51 of the secondary column 50 can be provided with an external thread on the outside, and the lower end of the main column 40 can be provided with an internal thread. The secondary column 50 is threadedly connected to the main column 40. At this time, the sealing structure 46 between the connecting portion 51 and the lower end of the main column 40 can be provided at the upper end and / or lower end of the inner side of the connecting portion 51 and the main column 40; of course, the connecting portion 51 of the secondary column 50 can be provided with an internal thread on the inside, and the outer side of the lower end of the main column 40 can be provided with an external thread. The secondary column 50 is threadedly connected to the main column 40. At this time, the sealing structure 46 between the connecting portion 51 and the lower end of the main column 40 can be provided at the upper end and / or lower end of the inner side of the connecting portion 51 and the main column 40.

[0076] In some embodiments, the connection portion 51 of the secondary column 50 can be screwed into the interior of the lower end of the main column 40 and sealed by the sealing structure 46. Therefore, in the embodiments of the present invention, there are no specific restrictions on the threaded connection structure between the main column 40 and the secondary column 50 and the sealing structure 46. It is sufficient that the pressing head 10 is locked and sealed by the threaded connection between the main column 40 and the secondary column 50.

[0077] Further, refer to Figures 2 to 4 as well as Figure 12 In some embodiments of the present invention, a plurality of communication holes 521 are provided on the clamping portion 52 , and the communication holes 521 are respectively located on the peripheral sides of the connecting portion 51 , and the communication holes 521 are used to connect the liquid storage chamber 33 and the first valve 32 .

[0078] Specifically, in this embodiment, a plurality of connecting holes 521 are further provided on the clamping portion 52 of the secondary column 50. These connecting holes 521 are located around the connecting portion 51 and are designed to connect the liquid storage chamber 33 and the first valve 32 to ensure that liquid can flow smoothly from the container into the liquid storage chamber 33 and then be discharged through the press pump. Specifically, the connecting holes 521 are arranged at specific locations on the clamping portion 52 to ensure that they do not affect the structural strength and stability of the secondary column 50. These connecting holes 521 not only provide a channel for liquid flow, but also serve to balance the pressure within the liquid storage chamber 33, thereby ensuring the smoothness and stability of the press pump when extracting and discharging liquid. In actual operation, when the pressing head 10 is pressed, the pressure in the liquid storage chamber 33 increases, and the liquid in the liquid storage chamber 33 quickly flows into the second liquid outlet channel 41 through the second valve 42 which is in the open state at this time. At this time, the first valve 32 is in the closed state, and the liquid in the liquid storage chamber 33 cannot flow back to the container through the first valve 32; on the contrary, when the pressing head 10 is lifted by the elastic member 44 or the user, the pressure in the liquid storage chamber 33 decreases. At this time, the liquid in the container quickly flows through the connecting hole 521 into the liquid storage chamber 33 through the first valve 32 which is in the open state at this time. At this time, the second valve 42 is in the closed state, and the liquid in the liquid storage chamber 33 cannot flow into the second liquid storage chamber 33 through the second valve 42. At this time, the discharged liquid can be replenished to the liquid storage chamber 33.

[0079] Reference Figures 2 to 4 as well as Figures 10 to 12 In some embodiments of the present invention, the secondary column 50 further includes a stopper portion 53, which is arranged at the lower end of the clamping portion 52 and clamped in the main body 30. A plurality of first limiting protrusions 531 are provided on the outer peripheral side of the stopper portion 53, and the plurality of first limiting protrusions 531 are distributed and spaced along the circumferential direction. A plurality of second limiting protrusions 34 are provided on the inner peripheral side of the main body 30, and the first limiting protrusions 531 and the second limiting protrusions 34 are alternately spaced.

[0080] Specifically, in this embodiment, an abutment top portion 53 is further added to the structure of the secondary column 50. This design is intended to enhance the connection stability between the secondary column 50 and the main body 30, prevent loosening or displacement during use, and thus improve the overall performance and safety of the press pump. Specifically, the abutment top portion 53 is arranged at the lower end of the clamping portion 52 and is tightly clamped in the main body 30. In order to ensure a stable connection, a plurality of first limiting protrusions 531 are designed on the outer peripheral side of the abutment top portion 53, and these protrusions are distributed at intervals along the circumferential direction. At the same time, a plurality of second limiting protrusions 34 are also correspondingly provided on the inner peripheral side of the main body 30. These first limiting protrusions 531 and the second limiting protrusions 34 are alternately arranged at intervals to form a unique limiting structure. When the secondary column 50 is installed in the main body 30, the first limiting protrusions 531 and the second limiting protrusions 34 will bite into each other to form a stable mechanical connection. This retaining structure not only prevents the secondary column 50 from rotating or shifting relative to the main body 30 during use and when the primary column 40 is rotated, but also effectively disperses and transmits the pressing force, protecting the internal structure from damage. It should be emphasized that to prevent the secondary column 50 from rotating or shifting relative to the main body 30 during use and when the primary column 40 is rotated, in addition to the alternating arrangement of the first retaining protrusions 531 and the second retaining protrusions 34, a protrusion can also be provided on the engaging portion 52 to engage with the main body 30.

[0081] Furthermore, in some embodiments of the present invention, a gap channel is provided between the first position-limiting protrusion 531 and the second position-limiting protrusion 34, connecting the liquid storage chamber 33 and the first valve 32. In this embodiment, a gap channel is further provided between the first position-limiting protrusion 531 and the second position-limiting protrusion 34. This design aims to provide a liquid flow path, improve the efficiency of the pump, and ensure stability and reliability.

[0082] Specifically, the gap channel between the first limiting protrusion 531 and the second limiting protrusion 34 ensures that they can connect the liquid storage chamber 33 and the first valve 32. This layout not only simplifies the flow path of the liquid, but also reduces the resistance during the flow process, thereby improving the response speed and liquid discharge efficiency of the press pump. In actual operation, when the user presses the button 10, the pressure in the liquid storage chamber 33 changes, and the liquid flows rapidly through the gap channel to balance the internal and external pressure differences. This design effectively prevents liquid leakage or damage to the pump body due to pressure imbalance, ensuring the stability and durability of the press pump during long-term use.

[0083] Reference Figures 3 and 4 as well as Figures 6 to 8 In some embodiments of the present invention, the first valve 32 includes a first limiting cavity 321 and a movable first valve body 322. The first valve body 322 is arranged in the first limiting cavity 321. The lower end of the abutting top 53 is located in the first limiting cavity 321. The abutting top 53 can abut the first valve body 322. The first valve body 322 is used to block or open the opening at one end of the first limiting cavity 321.

[0084] Specifically, this embodiment has carried out detailed design and optimization of the first valve 32. The first valve 32 is a key component that controls the flow of liquid from the container into the liquid storage chamber 33. The rationality of its design and performance directly affect the use effect of the press pump. Specifically, the first valve 32 includes a first limiting cavity 321 and a movable first valve body 322. The first limiting cavity 321 provides space for the first valve body 322 to move and ensures the stability and accuracy of the valve body during movement. The first valve body 322 is arranged in the first limiting cavity 321 and can be opened or closed under specific conditions, thereby controlling the flow of liquid.

[0085] It is worth noting that the lower end of the abutting portion 53 of the secondary column 50 is located in the first limiting cavity 321. This design enables the abutting portion 53 to directly abut the first valve body 322. When the user presses the button 10, as the main column 40 and the piston portion 43 move downward, the space in the liquid storage cavity 33 shrinks, causing a portion of the liquid in the liquid storage cavity 33 to be discharged from the second valve body 422 and the second liquid outlet channel 41 of the main column 40, while the other portion of the liquid passes through the connecting hole 521 to reach the first limiting cavity 321 and expel the first valve body 322 to the lower end of the first limiting cavity 321, thereby using the first valve body 322 to block the opening at the lower end of the first limiting cavity 321, preventing the liquid from flowing back into the container. On the contrary, when the user releases the button head 10 or lifts the button head 10, as the main column 40 and the piston part 43 move upward, the space of the liquid storage chamber 33 increases, so that the pressure in the liquid storage chamber 33 becomes smaller. At this time, the second valve body 422 is closed, and the liquid in the container is drawn into the liquid storage chamber 33. At this time, the liquid in the container enters the first valve 32, and the liquid displaces the first valve body 322 upward, thereby opening the opening at the lower end of the first limit chamber 321, thereby facilitating the liquid to enter the liquid storage chamber 33.

[0086] Furthermore, the design of the first valve body 322 takes durability and sealing into full consideration. Made of wear-resistant and corrosion-resistant materials, it ensures excellent performance over long-term use. Furthermore, the tight fit between the valve body and the limiting cavity effectively prevents liquid leakage and improves the overall performance of the pump.

[0087] Similarly, refer to Figures 3 and 4 as well as Figures 10 to 12 In some embodiments of the present invention, the second valve 42 includes a second limiting cavity 421 and a second valve body 422. The second limiting cavity 421 is located in the second liquid outlet channel 41. The second valve body 422 is movably arranged in the second limiting cavity 421. The second valve body 422 is used to block or open the opening at one end of the second limiting cavity 421.

[0088] According to the above embodiment, this embodiment further describes in detail the specific structure and function of the second valve 42. The second valve 42 is the same as the first valve 32. It is a key component for controlling the outflow of liquid from the liquid storage chamber 33 to the outside. The rationality of its design is crucial to ensuring the normal operation of the press pump and the smooth outflow of liquid. Specifically, the second valve 42 includes a second limiting chamber 421 and a second valve body 422. The second limiting chamber 421 is located in the second liquid outlet channel 41, which provides space for the second valve body 422 to move and ensures the stability and positioning accuracy of the valve body during movement. The second valve body 422 is movably arranged in the second limiting chamber 421, and can be opened or closed according to the working state of the press pump, thereby accurately controlling the outflow of liquid.

[0089] When the user presses the button 10, the main column 40 and piston 43 move downward, increasing the pressure within the liquid storage chamber 33. At this point, liquid enters the second valve 42 from the second liquid outlet channel 41. The second valve body 422, under the pressure of the liquid within the second limiting chamber 421, moves in the opening direction (i.e., upward in the figure), thereby opening the lower end of the second limiting chamber 421. This allows the liquid within the liquid storage chamber 33 to flow smoothly out through the second liquid outlet channel 41 for the user to use. Conversely, when the user releases or lifts the button 10, the main column 40 and piston 43 move upward under the action of the elastic member 44 or the user's operation, increasing the volume of the liquid storage chamber 33 and reducing the pressure within it. At this point, the second valve body 422, due to its own gravity, elastic restoring force, or the negative pressure within the liquid storage chamber 33, moves in the closing direction (i.e., downward in the figure), thereby blocking the lower end of the second limiting chamber 421. This prevents uncontrolled outflow of liquid when the pump is not operating, ensuring the safety and convenience of the pump. At the same time, the liquid in the container enters the first valve 32, which pushes the first valve body 322 upward, thereby opening the lower end of the first limiting cavity 321 and facilitating the liquid to enter the liquid storage cavity 33.

[0090] Furthermore, the design of the second valve body 422 takes durability and sealing into full consideration. Made of wear-resistant, corrosion-resistant, and resilient materials, it ensures excellent performance and sealing during long-term use. Furthermore, the tight fit between the second valve body 422 and the second limiting cavity 421 effectively prevents liquid leakage, improving the overall performance and reliability of the pump.

[0091] Reference Figures 3 and 4 as well as Figures 10 to 12 In some embodiments of the present invention, the pressing head 10 is detachably connected to the main column 40 , and the lower end of the pressing head 10 is sealingly engaged in the main column 40 .

[0092] In particular, the press head 10 is detachably connected to the main column 40, and the lower end of the press head 10 is sealingly engaged in the main column 40. This design not only facilitates the replacement and maintenance of the press head 10, but also ensures the sealing of the press pump during use to prevent liquid leakage. In a specific implementation, the main column 40 is the main supporting structure of the press pump, and a cavity matching the press head 10 is provided inside it. The lower end of the press head 10 is designed to be in a shape matching the cavity of the main column 40 and can be inserted into the cavity of the main column 40. In order to ensure sealing, a sealing structure (not shown in the figure) is provided between the lower end of the press head 10 and the cavity of the main column 40, such as a sealing ring, a sealing protrusion or a sealing gasket.

[0093] In terms of the connection between the button head 10 and the main column 40, this embodiment adopts a detachable connection method. Specifically, a snap-fit ​​structure can be provided at the lower end of the button head 10, and a corresponding slot can be provided in the cavity of the main column 40. When the button head 10 is inserted into the cavity of the main column 40, the snap-fit ​​structure will cooperate with the slot, thereby achieving a sealed connection between the button head 10 and the main column 40. At the same time, this snap-fit ​​connection method also makes it convenient for the user to disassemble the button head 10 at any time during use for replacement or repair. In addition, in order to further ensure the sealing performance, sealant or other sealing materials can be applied between the lower end of the button head 10 and the cavity of the main column 40. In this way, even during long-term use, liquid can be effectively prevented from leaking out through the connection between the button head 10 and the main column 40.

[0094] Furthermore, in some embodiments of the present invention, a third limiting protrusion 12 is provided on the outer peripheral side of the lower end of the pressing head 10, and a fourth limiting protrusion 45 is provided on the inner side wall of the upper end of the main column 40, and the third limiting protrusion 12 and the fourth limiting protrusion 45 are arranged alternately. This embodiment further provides a pressing pump, in which a third limiting protrusion 12 is provided on the outer peripheral side of the lower end of the pressing head 10, and a fourth limiting protrusion 45 is provided on the inner side wall of the upper end of the main column 40. In particular, these third limiting protrusions 12 and fourth limiting protrusions 45 are arranged alternately. This structure not only enhances the connection stability between the pressing head 10 and the main column 40, but also effectively prevents the pressing head 10 from unnecessary rotation or displacement during use.

[0095] In a specific implementation, the third limiting protrusion 12 can be designed as a series of protruding structures evenly distributed on the outer peripheral side of the lower end of the push head 10, while the fourth limiting protrusion 45 is a series of grooves or protrusions correspondingly arranged on the inner side wall of the upper end of the main column 40. Therefore, similar to the first limiting protrusion 531 and the second limiting protrusion 34, when the push head 10 is inserted into the main column 40, these protrusions and grooves will fit together to form a stable limiting structure. The alternating arrangement of the third limiting protrusion 12 and the fourth limiting protrusion 45 means that they form a staggered layout in space. This layout can effectively disperse the pressure at the connection point and improve the stability and durability of the connection. At the same time, it can also prevent the push head 10 from rotating when subjected to external force, ensuring the stability and reliability of the push head 10 of the press pump in the process of rotating to unlock the main column 40 and the secondary column 50. In addition, the design of this limiting protrusion can also simplify the installation process of the push head 10. The user only needs to align the third limiting protrusion 12 of the push head 10 with the fourth limiting protrusion 45 of the main column 40, and then gently push it in to achieve a stable connection. This design not only improves the user experience, but also greatly reduces the difficulty and error rate of installation. In general, the pressing pump of this embodiment achieves a stable connection between the pressing head 10 and the main column 40 by adopting the third limiting protrusion 12 and the fourth limiting protrusion 45 arranged at alternating intervals, effectively preventing the rotation and displacement of the pressing head 10. This design not only improves the stability and durability of the pressing pump, but also simplifies the installation process and enhances the user experience.

[0096] Reference Figures 9 to 12 In some embodiments of the present invention, a buckle portion 35 is provided on the upper edge of the body 30. The buckle portion 35 protrudes in the radial direction. A buckle groove 22 is provided on the inner side of the locking cover 20. The buckle portion 35 can be buckled into the buckle groove 22. A guide bevel (not shown) is provided on the inner side of the upper edge of the body 30. The guide bevel can be tightly attached to the buckle groove 22. This embodiment further provides a press pump, wherein the upper edge of the body 30 is specifically provided with a buckle portion 35, and the inner side of the locking cover 20 is correspondingly provided with a buckle groove 22. This design achieves a stable and sealed connection between the body 30 and the locking cover 20 through the mutual cooperation between the buckle portion 35 and the buckle groove 22, thereby ensuring the integrity and stability of the press pump.

[0097] In practice, the snap-fitting portion 35 is a radially protruding structure along the upper edge of the body 30. Its shape and size match the snap-fitting groove 22 inside the locking cover 20. To connect the body 30 and the locking cover 20, simply align the snap-fitting portion 35 with the snap-fitting groove 22. The pump is then screwed onto the container through the locking cover 20. The container's port gently presses the body 30 upward during the tightening process, causing the guide bevel on the inner side of the upper edge of the body 30 to slide into the snap-fitting groove 22, and the snap-fitting portion 35 snaps into the snap-fitting groove 22. Simultaneously, the snap-fitting portion 35 abuts against the snap-fitting groove 22. As the guide bevel on the inner side of the upper edge of the body 30 slides into the snap-fitting groove 22, it clings tightly to the side of the snap-fitting groove 22, achieving a tight and sealed connection. This snap-fitting method is not only simple and convenient, but also provides a secure and airtight connection. Once the buckle portion 35 and the buckle groove 22 are successfully buckled, a tight connection is formed between them, which can effectively prevent the relative movement or falling off between the body 30 and the locking cover 20. This design greatly improves the stability and safety of the press pump during use.

[0098] Further, refer to Figures 9 to 12In some embodiments of the present invention, a boss 36 is provided around the outer wall of the upper end of the body 30, and the upper side of the boss 36 abuts against the inner side of the locking cover 20. This embodiment provides a press pump in which the upper outer wall of the body 30 is specifically provided with a boss 36 structure, and the upper side of the boss 36 can abut against the inner side of the locking cover 20. This design further enhances the connection stability and sealing between the body 30 and the locking cover 20 through the mutual abutment between the boss 36 and the inner side of the locking cover 20. In a specific embodiment, the boss 36 is a raised structure provided in an annular manner along the outer wall of the upper end of the body 30, and has a certain width and height. When the locking cover 20 is installed on the main body 30, the inner side of the locking cover 20 will fit tightly against the upper side of the boss 36, thereby forming a stable support and limiting effect; at the same time, when the pressing pump is screwed onto the container through the locking cover 20, the port of the container can also be pressed against the lower end of the boss 36, so that the main body 30 is tightly clamped between the locking cover 20 and the container, improving the stability of the connection. The design of the boss 36 not only increases the contact area between the main body 30 and the locking cover 20, improving the stability of the connection, but also effectively prevents liquid from leaking out from the connection between the main body 30 and the locking cover 20. This is because the tight fit between the upper side of the boss 36 and the inner side of the locking cover 20 forms an additional sealing barrier, greatly enhancing the sealing performance of the pressing pump. In addition, the boss 36 can also serve as a positioning structure during the installation process. To install the lock cover 20, the user simply aligns the lock cover 20 with the boss 36 on the upper end of the body 30 and gently presses, causing the snap-fit ​​portion 35 to slide into the snap-fit ​​groove 22, thereby properly securing the lock cover 20 to the body 30. This design simplifies the installation process, improves installation efficiency, and reduces the possibility of installation errors. In summary, the press pump of the present invention achieves a stable connection and a good seal between the body 30 and the lock cover 20 by providing a boss 36 around the outer wall of the upper end of the body 30 and allowing the upper side of the boss 36 to abut against the inner side of the lock cover 20.

[0099] Reference Figures 9 to 12 In some embodiments of the present invention, the inner sidewall of the locking cover 20 is provided with a first skirt portion 23 extending in the axial direction. The first skirt portion 23 can be sleeved between the lower end of the pressing head 10 and the main body 30. The upper sidewall of the main body 30 is provided with a vent hole 37, which is located on one side of the first skirt portion 23. A notable feature of the pressing pump provided in this embodiment lies in the first skirt portion 23 provided on the inner sidewall of the locking cover 20 and the matching vent hole 37 on the upper sidewall of the main body 30. This unique structure not only optimizes the sealing performance of the pump but also ensures smooth operation of the pump during use.

[0100] Specifically, the inner sidewall of the lock cover 20 is provided with a first skirt portion 23 extending in the axial direction. When the lock cover 20 is installed on the pump body, this first skirt portion 23 can be mounted between the lower end of the push head 10 and the main body 30, forming an additional sealing layer. This design effectively prevents liquid from leaking through the gap between the push head 10 and the main body 30 during the pumping process, thereby significantly improving the sealing and operating efficiency of the pump. At the same time, a vent hole 37 is provided on the upper side wall of the main body 30, and the vent hole 37 is located on one side of the first skirt portion 23. The design of the vent hole 37 ensures the smooth discharge of internal gas during the pump pressing process, preventing problems such as poor pumping or liquid splashing due to changes in air pressure. The layout of the vent hole 37 on one side of the first skirt portion 23 utilizes the sealing effect of the first skirt portion 23, ensuring the ventilation effect while preventing liquid from leaking through the vent hole 37. In actual use, when the user presses the button 10, the liquid in the liquid storage chamber 33 is squeezed out. At this time, the vent hole 37 allows the gas inside the piston chamber 31 to be replenished through the vent hole 37 in a timely manner, ensuring smooth pumping. The first skirt 23 plays a key sealing role in this entire process, ensuring the efficient and safe operation of the pump.

[0101] Similarly, in some embodiments of the present invention, referring to Figures 1 to 3 as well as Figure 7 The pressing head 10 also includes a second skirt 13, which extends in the axial direction. The second skirt 13 is sleeved on the outside of the first liquid outlet channel 11, and the lower end of the second skirt 13 can abut against the outer upper end of the lock cover 20.

[0102] The push-button 10 of the pump provided in this embodiment features a special design with a second skirt 13. Specifically, in addition to its primary pressing function, the push-button 10 also includes this second skirt 13, which extends axially. When the push-button 10 is installed on the pump body, the second skirt 13 fits over the outer side of the first liquid outlet channel 11, forming a protective layer that helps prevent external impurities or dust from entering the first liquid outlet channel 11, thereby ensuring the purity of the liquid and the proper operation of the pump. More importantly, the lower end of the second skirt 13 is designed to abut against the outer upper end of the locking cover 20. This design not only enhances the stability of the connection between the push-button 10 and the locking cover 20, preventing the push-button 10 from shaking or falling off during use, but also further improves the pump's sealing performance by adding a sealing layer. In actual use, when the user presses the push-button 10, the second skirt 13 fits tightly against the outer upper end of the locking cover 20 as the push-button 10 moves downward, effectively preventing liquid leakage through this connection.

[0103] According to a third embodiment of the present invention, a container (not shown) includes a pressure pump according to any one of the second embodiments. The container includes a container end, a locking cap 20 is threadedly connected to the container end via a first locking screw 21, and a portion of the pressure pump structure is disposed within the container.

[0104] Specifically, the container includes a container end, with the locking cap 20 of the push pump threadedly connected to the container end via a first locking screw 21. This connection ensures a tight connection between the locking cap 20 and the container end while facilitating assembly and disassembly operations for the user. The lower half of the push pump structure is placed inside the container, allowing the pump body 30 to come into direct contact with the liquid within the container. When the user needs to pump liquid, they simply press the push pump head 10, and the liquid within the pump enters the push pump through a port at the lower end of the body 30. The liquid is then pumped out through the first and second liquid outlet channels 11 and 41 of the push pump for use by the user. Due to the excellent sealing performance and stable pumping effect of the push pump, it can ensure smooth pumping of liquid, avoiding leakage and waste. In addition, due to the simple structure and compact size of the push pump, it does not take up too much container space, allowing the container to maintain sufficient capacity while still achieving convenient liquid pumping function. This design not only improves the efficiency of the container but also provides users with a more convenient and efficient user experience.
