Description

Technical Field

[0001] This utility model relates to the field of vacuum pump technology, and in particular to a small-volume handheld vacuum pump. Background Technology

[0002] Vacuum sealing offers numerous benefits, encompassing food preservation, item storage, and item protection. For food, vacuum sealing effectively isolates the food from air, inhibiting the growth of bacteria, mold, and other microorganisms, thus preserving the freshness and nutritional value of ingredients for a longer period and significantly extending shelf life. For storage, vacuum sealing significantly reduces the volume of fluffy items like clothing, thereby minimizing space usage. Therefore, vacuum sealers have positive implications for people's lives and production.

[0003] On the market, vacuum sealers are mostly large industrial devices with complex structures, large sizes, and high prices, making them suitable only for large-scale production scenarios. With technological advancements and increasing household demand, smaller vacuum sealers have gradually emerged. However, existing household vacuum sealers are mainly used for storing items. Although they are smaller than before, they are still relatively large, making them inconvenient to carry, and they have poor compatibility, not suitable for small food storage bags.

[0004] Therefore, it is necessary to improve existing technologies. Utility Model Content

[0024] The following embodiments illustrate the present invention, but the present invention is not limited to these embodiments. Modifications to the specific implementation of the present invention or equivalent substitutions for some technical features, without departing from the spirit of the present invention, should all be covered within the scope of the technical solution claimed by the present invention.

[0025] like Figures 1 to 5 As shown, this embodiment provides a small-volume handheld vacuum pump, including a housing assembly 1, a sealing member 2, a vacuum pump 3, a rechargeable battery 4, and a control component 5. The housing assembly 1 includes a housing 11 and a base 12, which are detachably connected together by screws. The vacuum pump 3 and the rechargeable battery 4 are arranged side by side on the base 12. The control component 5 is located on the top of the vacuum pump 3. A first opening 111 is provided at the top of the housing 11, and a switch button 6 is provided in the first opening 111. The switch button 6 is connected to the control component 5. A second opening 121 is provided at the lower end of the base 12, and the sealing member 2 is located in the second opening 121. The vacuum pump 3 is provided with an air extraction port 31, which is located in the sealing member 2.

[0026] This invention provides a small-sized handheld vacuum pump that is not only compact and easy to operate, but can also be used for vacuum packaging in various scenarios.

[0027] Specifically, the control component 5 is a control circuit board, the switch button 6 is fixed inside the first opening 111, and the control component 5 is disposed between the switch button 6 and the vacuum pump 3. The control component 5 is connected to the switch button 6, the vacuum pump 3, and the rechargeable battery 4, respectively. Users can perform vacuuming operations on items and food by using the switch button 6, which is simple and convenient.

[0028] Preferably, the lower end of the base 12 is provided with a first connecting ring 122, the middle of the first connecting ring 122 is the second opening 121, the bottom end of the first connecting ring 122 is provided with a first slot 123, the outer side of the first slot 123 extends downward to form a second slot 124, the inner side of the bottom end of the second slot 124 forms an insert 125, and the outer side of the second slot 124 is connected to the base 12. This design facilitates the sealing member 2 to be locked at the second opening 121, making it difficult for the sealing member 2 to fall off, thus ensuring the integrity and stability of the equipment.

[0029] Preferably, the sealing member 2 includes a first sealing plate 21, a connecting portion 22, a second sealing plate 23, and a sealing lip 24. The outer diameter of the first sealing plate 21 is adapted to the inner diameter of the second opening 121, and the outer diameter of the second sealing plate 23 is adapted to the inner diameter of the second slot 124. The upper part of the sealing lip 24 forms a groove 241 outward, and the inner side of the sealing lip 24 is connected to the bottom end of the second sealing plate 23. The insert 125 is inserted into the groove 241. This design allows the sealing member 2 to be fixedly connected to the base 12. The design of the sealing lip 24 also allows the vacuum packaging opening to be better secured at the sealing member 2, preventing the vacuum packaging opening from separating from the sealing lip 24 during vacuuming and causing air leakage.

[0030] Furthermore, a first connection port 25 is provided between the first sealing plate 21 and the connecting portion 22, and a second connection port 26 is provided between the bottom end of the connecting portion 22 and the second sealing plate 23. The first connection port 25 is connected to the second connection port 26 and is larger in diameter than the second connection port 26. The air extraction port 31 is inserted into the first connection port 25 and is press-fitted to it. This ensures a tight connection between the air extraction port 31 and the first connection port 25.

[0031] Preferably, the first sealing sheet 21, the connecting portion 22, the second sealing sheet 23, and the sealing lip 24 are integrally formed. Preferably, they are made of rubber material using a single injection molding process to ensure the airtightness of the sealing component 2.

[0032] Furthermore, the housing 11 has several evenly distributed strip grooves 13 on both sides. This increases the friction between the hand and the vacuum pump, making it easier for the user to operate.

[0033] Furthermore, a charging port 14 is provided on one side of the housing 11. This facilitates charging and extending the battery life of the vacuum pump.

[0034] Furthermore, a positioning part 15 is provided inside the base 12, and the rechargeable battery 4 and the vacuum pump 3 are disposed within the positioning part 15. This fixes the positions of the rechargeable battery 4 and the vacuum pump 3.

[0035] It's worth noting that this compact handheld vacuum sealer is small and lightweight, and can be used not only for compressing clothing into vacuum bags, but also for household food preservation bags, allowing users to vacuum-seal and preserve pre-packaged food anytime, anywhere at home.

[0036] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
