[0001] The utility model relates to the technical field of vacuum pumps, in particular to an all-plastic high-barrier vacuum pump. Background Art

[0002] Existing packaging containers for liquid daily chemicals such as shampoo, shower gel, etc. mostly use piston pumps with straws. When in use, the piston pump with straw is installed on the container, and the straw is extended into the container to suck out the liquid in the container.

[0003] The existing all-plastic high-barrier vacuum pump has a short shelf life. After long-term use, it may face the problem of reduced sealing performance, resulting in the inability to effectively isolate the internal gas, which in turn causes the odor in the package to easily escape, affecting the original aroma preservation effect of the contents. Utility Model Content

[0004] Based on this, the purpose of the utility model is to provide an all-plastic high-barrier vacuum pump to solve the technical problem that the sealing performance may be reduced after long-term use.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an all-plastic high-barrier vacuum pump, comprising a barrier tube body main body, the top of the barrier tube body main body is connected to a barrier tube body head through a tube body fixed thread, the interior of the barrier tube body head is clamped with a down-pressure valve through a down-pressure valve mounting buckle, a first enclosed space is arranged above the down-pressure valve, a pump plug is arranged above the first enclosed space, an upper valve is arranged at the bottom of the inner wall of the pump plug, a third enclosed space is arranged above the upper valve, and an integrated floating tube is arranged above the third enclosed space.

[0006] By adopting the above technical solution, two independent storage areas are created, which effectively isolate the intrusion of external air and water vapor. This design greatly enhances the anti-oxidation and anti-moisture capabilities of the paste in the pump, significantly improves the preservation quality and shelf life of the paste, and ensures that the paste remains fresh and fragrant for a long time. This is especially important for cosmetics, pharmaceuticals or food pastes that need to be stored for a long time, providing users with a more hygienic, safe and high-quality product experience.

[0007] Furthermore, a gasket is sleeved on the outer side of the pump plug, a plastic spring limiting rib is fixedly connected to the top of the gasket, and a plastic spring is clamped on the outer side of the plastic spring limiting rib.

[0008] By adopting the above technical solution, effective fixation and sealing of the pump plug is achieved, and at the same time an elastic rebound function is provided, thereby ensuring smoothness and continuity during the compression and rebound process of the pump plug, and effectively improving the suction and release efficiency of the pump.

[0009] Furthermore, the integrated floating tube and the pump plug are clamped together by a floating tube buckle, and a button is abutted on the top of the integrated floating tube.

[0010] By adopting the above technical solution, the stable movement of the integrated floating tube under the guidance of the pump plug is achieved, ensuring that the integrated floating tube can move up and down smoothly under pressure without being separated from the pump plug, thereby ensuring the efficiency and accuracy of the continuous suction and release operations of the pump.

[0011] Furthermore, the outer side of the top of the barrier tube body head is fixedly connected to the barrier tube body, and the barrier tube body is connected to the upper cover through an upper cover buckle.

[0012] By adopting the above technical solution, not only the installation and disassembly process of the upper cover is simplified, improving the convenience during use, but also ensuring the sealing of the entire vacuum pump, effectively preventing the entry of air and impurities, and protecting the purity and freshness of the internal paste.

[0013] Furthermore, the bottom of the barrier tube body is clamped with a bottom cover via a bottom cover buckle, and the interior of the barrier tube body is slidably connected with a lower piston.

[0014] By adopting the above technical solution, the bottom cover can be quickly disassembled and assembled, and the internal cleaning and maintenance are convenient. At the same time, the sealing of the device during use is ensured to prevent the internal paste from leaking or external pollutants from entering.

[0015] Furthermore, the upper cover is connected to the dust cover by means of a dust cover buckle.

[0016] By adopting the above technical solution, an extra protective layer is added, which significantly improves the hygiene and safety of the vacuum pump. The dust cover can effectively prevent dust and other pollutants from entering the inside of the pump, protect the internal paste from contamination, extend the shelf life of the paste and maintain its purity.

[0017] Furthermore, a second enclosed space is provided between the lower piston and the barrier tube body.

[0018] By adopting the above technical solution, the second enclosed space acts as a buffer zone, further isolating the internal paste from the external environment, enhancing the anti-oxidation and water vapor resistance, and ensuring that the paste remains fresh and pure for a long time.

[0019] Furthermore, the interior of the second enclosed space is filled with paste.

[0020] By adopting the above technical solution, full utilization and storage of the paste in the pump are ensured, which not only maximizes the storage capacity of the paste and ensures that the user can smoothly obtain the required paste each time use, but also improves the suction and release efficiency of the paste.

[0021] Furthermore, the top of the plastic spring is in conflict with the integrated floating tube.

[0022] By adopting the above technical solution, it is ensured that the pump plug can automatically return to the initial position after each depression, which not only improves the convenience during use and reduces the user's operating force, but also ensures the continuous use of the pump, so that it can be prepared for the next squeezing after each use.

[0023] Furthermore, a friction groove is provided on the outer side of the dust cover, and a plurality of the friction grooves are provided.

[0024] By adopting the above technical solution, the user's grip and operating convenience when opening or closing the dust cover are improved. The friction groove provides an additional friction surface, reducing the possibility of hand slippage, so that the user can more easily control the opening and closing of the dust cover during use, especially when the hands are wet or the use environment is complex, which can ensure the safety and reliability of the operation.

[0025] In summary, the utility model mainly has the following beneficial effects:

[0026] 1. The utility model sets the first enclosed space and the third enclosed space, and divides the space again, so that the isolation pump has excellent oxygen, carbon dioxide and water vapor barrier properties, excellent quality preservation ability, and keeps the paste fresh and fragrant for a long time;

[0027] 2. The utility model provides a plastic spring, and the all-plastic pump body can meet the one-time recycling requirements. The plastic spring is made of food-grade plastic, which completely avoids the risk of metal springs contaminating the paste and ensures hygiene and safety;

[0028] 3.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.

[0035] The following describes an embodiment of the utility model based on its overall structure.

[0036] Embodiment 1:

[0037] A fully plastic high barrier vacuum pump, such as Figure 1-Figure 4 As shown, it includes a barrier tube body main body 13, the top of the barrier tube body main body 13 is connected to the barrier tube body head 12 through a tube body fixing thread 20, the interior of the barrier tube body head 12 is clamped with a down-pressing valve 9 through a down-pressing valve mounting buckle 18, a first enclosed space 22 is arranged above the down-pressing valve 9, a pump plug 6 is arranged above the first enclosed space 22, an upper valve 21 is arranged at the bottom of the inner wall of the pump plug 6, a third enclosed space 23 is arranged above the upper valve 21, and an integrated floating tube 3 is arranged above the third enclosed space 23, creating two independent storage areas, effectively isolating the intrusion of external air and water vapor, this design greatly enhances the anti-oxidation and anti-moisture capabilities of the paste in the pump, significantly improves the preservation quality and shelf life of the paste, and ensures the quality of the paste. The paste remains fresh and fragrant for a long time, which is especially important for cosmetics, medicines or food pastes that need to be preserved for a long time, providing users with a more hygienic, safe and high-quality product use experience. At the same time, the setting of the downward pressure valve 9 and the first enclosed space 22, as well as the configuration of the upper valve 21 and the third enclosed space 23 in the pump plug 6, constitute an effective dual-valve control system. This system can open the upper valve 21 to allow the paste to enter the third enclosed space 23 when the pump plug 6 is pressed down, and generate negative pressure by closing the downward pressure valve 9 and the upper valve 21 when the pump plug is released, so as to suck the paste back to the first enclosed space 22 to prepare for the next suction, which not only improves the efficiency of suction and release of the paste, but also ensures the hygiene of the process and the anti-pollution of the paste.

[0038] See also Figure 1 and Figure 2 A gasket 7 is sleeved on the outer side of the pump plug 6, and a plastic spring limiting rib 15 is fixedly connected to the top of the gasket 7. The plastic spring 5 is engaged on the outer side of the plastic spring limiting rib 15, which realizes the effective fixation and sealing of the pump plug and provides an elastic rebound function, ensuring the stability and continuity during the compression and rebound of the pump plug, and effectively improving the suction and release efficiency of the pump. At the same time, the introduction of the plastic spring 5 further enhances the environmental protection characteristics and safety of the entire vacuum pump. Since the plastic spring 5 and the limiting rib 15 are made of food-grade plastic materials, not only the paste contamination problem that may be introduced by the metal spring is avoided, but also the hygiene and safety during use are guaranteed, which further contributes to the recycling and reuse of the vacuum pump, meets the current environmental protection requirements, and provides users with a safe and environmentally friendly use option.

[0039] See also Figure 1 and Figure 2 The integrated floating tube 3 and the pump plug 6 are connected with each other through the floating tube buckle 14, and the top of the integrated floating tube 3 is in contact with the button 2, which realizes the stable movement of the integrated floating tube 3 under the guidance of the pump plug 6, and ensures that the integrated floating tube 3 can move up and down smoothly under the action of pressure without separating from the pump plug 6, thereby ensuring the efficiency and accuracy of the continuous suction and release operation of the pump. At the same time, the button 2 in contact with the top of the integrated floating tube 3 provides the user with an intuitive and easy-to-operate control interface. The user can directly drive the integrated floating tube 3 and the pump plug 6 to be pressed down together by pressing the button 2, thereby realizing the suction and extrusion of the paste, thereby improving the convenience and user experience during use.

[0040] See also Figure 1 and Figure 2 The top outer side of the barrier tube body head 12 is fixedly connected to the barrier tube body 8, and the barrier tube body 8 is connected to the upper cover 4 through the upper cover buckle 17, which not only simplifies the installation and disassembly process of the upper cover 4 and improves the convenience during use, but also ensures the sealing of the entire vacuum pump, effectively prevents the entry of air and impurities, and protects the purity and freshness of the internal paste. At the same time, the use of the upper cover buckle 17 increases the reliability and safety of the entire device. Through the precise snap-fit ​​mechanism, the upper cover 4 can be firmly fixed on the barrier tube body 8 to prevent accidental opening during use, avoiding leakage or contamination of the paste.

[0041] See also Figure 1 and Figure 3The bottom of the barrier tube body 13 is clamped with the bottom cover 11 through the bottom cover buckle 19, and the interior of the barrier tube body 13 is slidably connected with the lower piston 10, which facilitates the rapid disassembly and assembly of the bottom cover 11 and the internal cleaning and maintenance, while also ensuring the sealing of the device during use to prevent internal paste leakage or external contaminants from entering. At the same time, the sliding connection design of the lower piston 10 inside the barrier tube body 13 enables the lower piston 10 to automatically slide according to the internal pressure changes during the operation of the pump plug, effectively adjusting the size of the internal space and providing power for the suction and discharge of the paste.

[0042] See also Figure 1 and Figure 2 The upper cover 4 is connected to the dust cover 1 through the dust cover buckle 16, which adds an extra protective layer and significantly improves the hygiene and safety of the vacuum pump. The dust cover 1 can effectively prevent dust and other pollutants from entering the pump, protect the internal paste from contamination, extend the shelf life of the paste and maintain its purity. At the same time, the addition of the dust cover 1 also improves the user experience and convenience of the vacuum pump. Since the dust cover buckle 16 provides a convenient connection method, the user can easily open or close the dust cover 1 without using any tools, making the daily use and maintenance of the product easier and more convenient.

[0043] See also Figure 1 and Figure 3 A second enclosed space 24 is provided between the lower piston 10 and the barrier tube body 13. The second enclosed space 24 serves as a buffer zone, further isolating the internal paste from the external environment, enhancing the anti-oxidation and anti-water vapor performance, and ensuring that the paste remains fresh and pure for a long time. At the same time, the setting of the second enclosed space 24 also improves the suction and output efficiency of the vacuum pump. During the operation of the pump, the second enclosed space 24 helps to form a more effective negative pressure environment, which is conducive to the smooth suction and discharge of the paste, making each suction and release action more precise and efficient.

[0044] See also Figure 1 The interior of the second confined space 24 is filled with paste, ensuring the full utilization and storage of the paste in the pump, which not only maximizes the storage capacity of the paste and ensures that the user can smoothly obtain the required paste every time use, but also improves the suction and release efficiency of the paste. At the same time, the paste filled in the second confined space 24 further enhances the anti-leakage ability of the vacuum pump. During operation, even if the paste in the main storage area is sucked out, the paste in the second confined space can provide additional supply for the pump, ensuring the continuity and stability of the suction process.

[0045] See also Figure 1 and Figure 2The top of the plastic spring 5 and the integrated floating tube 3 are in conflict with each other, ensuring that the pump plug 6 can automatically return to its initial position after each depression. This not only improves the convenience during use and reduces the user's operating force, but also ensures the continuous use of the pump, so that it can be prepared for the next squeezing after each use. At the same time, the direct contact design between the plastic spring 5 and the integrated floating tube 3 enhances the structural stability and durability of the entire pump body. During operation, the elastic force of the plastic spring 5 directly acts on the integrated floating tube, which can effectively transmit power and ensure the movement of components such as the pump plug 6 and the downward pressure valve 9.

[0046] The implementation principle of the utility model is as follows: first, when the button 2 is pressed down, the integrated floating tube 3, the pump plug 6 and the plastic spring 5 are pressed down at the same time, so that the first enclosed space 22 becomes smaller, the paste in the space is squeezed, the upper valve 21 is squeezed open, the paste enters the third enclosed space 23 inside the integrated floating tube 3, and squeezes the button 2 from the mouth of the integrated floating tube 3 to achieve extrusion. Since the downward pressure valve 9 is also squeezed and sealed with the barrier tube head 12, the paste can only flow upward. When the button is released, the plastic spring 5 restores the original state, and the elastic force moves the integrated floating tube 3 and the pump plug 6 upward. The enclosed space 1 generates negative pressure to close the upper valve 21, and the downward pressure valve 9 opens. Due to the action of atmospheric pressure, the paste in the second enclosed space 24 is squeezed into the enclosed space 1 until the enclosed space 1 is filled with paste and the filling is completed. At the same time, the paste inside the barrier tube body 13 is reduced, and a vacuum is generated inside, so that the lower piston 10 moves upward due to the negative pressure, and the squeezed paste contacts the barrier tube body 13 again, waiting for the next suction.

[0047] Embodiment 2:

[0048] See also Figure 4 A friction groove 25 is provided on the outer side of the dust cover 1, and a plurality of friction grooves 25 are provided, which improves the user's grip and operating convenience when opening or closing the dust cover. The friction groove 25 provides an additional friction surface, reduces the possibility of hand slippage, and allows the user to more easily control the opening and closing of the dust cover 1 during use, especially when the hands are wet or the use environment is complex, which can ensure the safety and reliability of the operation. At the same time, the provision of multiple friction grooves 25 not only enhances the practicality of the dust cover 1, but also improves the aesthetics and design sense of the dust cover 1.

[0049] The implementation principle of the utility model is that the multiple friction grooves 25 can increase the friction force, making it easier to open the dust cover 1.
