Description

Technical Field

[0001] This utility model relates to the field of kitchenware, and more particularly to a novel sealing device for food preservation bags. Background Technology

[0002] As people's living standards improve, the usage rate of sous-vide cookers is also increasing. Sous-vide cookers use relatively low temperatures to heat food in a water bath for a long time, which can ensure the tenderness of food while avoiding the destruction of its nutrients, and is therefore very popular. However, since sous-vide cookers require food to be placed in bags and vacuum-sealed, most existing vacuum sealing devices have relatively complex structures, which not only result in high operating costs but also cumbersome operation, leading to a poor user experience. Utility Model Content

[0003] This application provides a novel sealing device for food preservation bags to solve the technical problems of high operating costs, cumbersome operation, and poor user experience of existing vacuum sealing equipment.

[0004] To solve the above-mentioned technical problems, this utility model provides a novel sealing device for food preservation bags, including a base detachably disposed on the inner side of the food preservation bag wall and a sleeve assembly correspondingly disposed on the outer side of the food preservation bag wall and matching the base. The sleeve assembly is adapted to be detachably sleeved on the outer side of the base. The base has an airflow channel communicating with the internal space of the food preservation bag. The sleeve assembly has a communication port corresponding to and communicating with the airflow channel. A sealing element is limited in the communication port to close the communication port. The sealing element has a needle slit for vacuuming the inside of the food preservation bag. By providing the insertion slit on the sealing element of the sealing device, a vacuum needle can be inserted into the food storage bag to create a vacuum. After vacuuming, the insertion slit automatically closes due to the characteristics of the sealing element, thus sealing the food storage bag. This not only effectively improves user convenience but also reduces the difficulty of vacuum sealing food storage bags, thereby enhancing the user experience. Furthermore, the detachable nature of the sealing device allows users to easily disassemble and reuse it after use, effectively reducing user costs and further improving the user experience.

[0005] In one optional embodiment, the periphery of the communication port is provided with an extension portion extending towards the base. Multiple outwardly extending snap-fit ​​portions are provided on the outer side of the extension portion. Multiple snap-fit ​​grooves are provided within the airflow channel that can engage with the snap-fit ​​portions. When the sleeve assembly is fitted onto the base, the extension portion is adapted to extend into the airflow channel so that the snap-fit ​​portions engage with the snap-fit ​​grooves. By using the snap-fit ​​portions and the snap-fit ​​grooves to snap the sleeve assembly onto the base, the connection structure between the sleeve assembly and the base is simplified, thereby reducing production and user costs. Furthermore, it allows users to better disassemble and connect the sleeve assembly and the base for reuse, effectively improving user convenience.

[0006] In an optional embodiment, one end of the extension adjacent to the base is adapted to be recessed inward to form a constricted portion, and a sealing groove communicating with the communication opening is adapted to be formed between the constricted portion and the extension, with the sealing element at least partially confined within the sealing groove. The sealing groove is adapted to position and / or limit the installation of the sealing element. Positioning and / or limiting the sealing element through the sealing groove not only effectively reduces the installation difficulty of the sealing element, thereby reducing production and user costs, but also reduces the possibility of the sealing element failing to seal properly or slipping into the food storage bag, thus ensuring the connection stability and sealing stability of the sealing element and improving the user experience.

[0007] In an optional embodiment, the sleeve assembly includes a sleeve detachably fitted onto the outside of the base and a cover covering the sleeve. The cover has a clearance opening corresponding to and communicating with the communication port. The periphery of the clearance opening has an abutment extending towards the base, the abutment being adapted to abut against the sealing element. The abutment is adapted to limit the sealing element, thereby preventing the sealing element from detaching from the sealing groove and causing sealing failure, effectively ensuring the connection stability and sealing stability of the sealing element.

[0008] In an optional embodiment, a fastening assembly is provided between the sleeve and the cover, and the cover is adapted to be detachably fastened to the sleeve via the fastening assembly. The fastening assembly allows for a detachable fastening between the cover and the sleeve, which not only simplifies the connection structure between the cover and the sleeve, thereby reducing the production cost and user cost of the sealing device, but also facilitates the user's separation of the cover and the sleeve for disassembly, cleaning, and replacement of the sealing element, effectively ensuring the performance stability and hygiene of the sealing device.

[0009] In one optional embodiment, one end of the cover is adapted to be hinged to the sleeve, and the other end is adapted to be detachably fastened to the sleeve by a fastening assembly. By hinged one end of the cover to the sleeve, the user can easily flip the cover to separate and fasten the cover from the sleeve, effectively improving user convenience and user experience.

[0010] In one optional embodiment, the base has a plurality of toothed blades extending toward the sleeve assembly around the airflow channel at one end adjacent to the sleeve assembly. These toothed blades create openings in the wall of the food storage bag when the sleeve assembly is fitted onto the base, forming a vacuum port for evacuating the contents of the food storage bag. By providing the toothed blades at one end of the base adjacent to the sleeve assembly, the base can automatically create openings in the wall of the food storage bag when fitted with the sleeve assembly, facilitating vacuuming and significantly improving user convenience.

[0011] In one optional embodiment, the base has an outwardly extending annular flange at its bottom. When the sleeve assembly is fitted onto the outside of the base, the sleeve assembly is adapted to abut against the annular flange. The annular flange is adapted to limit the installation of the sleeve assembly. By limiting the installation of the sleeve assembly through the annular flange, the installation difficulty of the sleeve assembly can be effectively reduced, and the user's misoperation can be avoided, which could lead to excessive fit between the sleeve assembly and the base, resulting in damage to the toothed cutter and / or scratches to the sleeve assembly. This effectively improves the user experience.

[0012] In an optional embodiment, the sleeve assembly and the annular flange have mating portions and corresponding mating grooves on their opposing surfaces, respectively. When the sleeve assembly is fitted onto the outside of the base, the mating portions are adapted to engage with the mating grooves. The mating portions and the mating grooves are adapted to limit the installation of the sleeve assembly, thereby reducing the possibility of the sleeve assembly sliding freely during installation and thus loosening or falling off. Simultaneously, the mating portions and the mating grooves are adapted to seal the connection between the sleeve assembly and the base, effectively ensuring the sealing stability of the sealing device and thus improving the performance stability of the sealing device.

[0013] In one optional embodiment, the sleeve assembly has a plurality of anti-slip portions vertically spaced on its side, the anti-slip portions being adapted to protrude from the outer surface of the sleeve assembly. The anti-slip portions are adapted to provide an anti-slip function; by providing the anti-slip portions on the outer surface of the sleeve assembly, the slippage that occurs when the user holds the sleeve assembly can be reduced, allowing the user to better grip the sleeve assembly for installation and removal, effectively improving user convenience and user experience.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application, by providing the pin slot on the sealing element of the sealing device, enables the insertion of a vacuum needle into the food storage bag to create a vacuum. After vacuuming, the pin slot automatically closes due to the inherent properties of the sealing element, thus sealing the food storage bag. This not only effectively improves user convenience but also reduces the difficulty of vacuum sealing, thereby enhancing the user experience. Furthermore, the detachable nature of the sealing device allows users to easily disassemble and reuse it after use, effectively reducing user costs and further improving the user experience.

[0028] Appendix Figure 1 To be continued Figure 6The diagram shows a novel sealing device for a food storage bag provided by this utility model. The sealing device includes a base 10 detachably disposed on the inner side of the food storage bag wall and a sleeve assembly 20 correspondingly disposed on the outer side of the food storage bag wall and matching the base 10. The sleeve assembly 20 is adapted to be detachably sleeved on the outer side of the base 10. The base 10 is provided with an airflow channel 11 communicating with the internal space of the food storage bag. The sleeve assembly 20 is provided with a connecting port 211 corresponding to and communicating with the airflow channel 11. A sealing element 23 made of elastic high-temperature resistant material such as rubber or silicone is limited and sealed in the connecting port 211. The sealing element 23 is provided with a needle slit 231 for vacuuming the inside of the food storage bag. By providing the insertion slot 231 on the sealing element 23 of the sealing device, a vacuum needle can be inserted into the food storage bag to vacuum the bag. After vacuuming, the insertion slot 231 can be automatically closed by the sealing element 23 itself to vacuum seal the food storage bag. This not only effectively improves the convenience of use for users but also reduces the difficulty of vacuum sealing the food storage bag, thereby improving the user experience. At the same time, the detachable feature of the sealing device allows users to freely disassemble the sealing device for reuse after use, effectively reducing the user's operating costs and improving the user experience.

[0029] like Figure 5 and Figure 6 As shown, in an optional embodiment, the periphery of the connecting port 211 is provided with an extension portion 212 extending towards the base 10. Multiple outwardly extending engaging portions 213 are provided on the outer side of the extension portion 212. The airflow channel 11 is provided with multiple engaging slots 12 that can engage with the engaging portions 213. When the sleeve assembly 20 is fitted onto the base 10, the extension portion 212 is adapted to extend into the airflow channel 11 so that the engaging portions 213 engage with the engaging slots 12. By using the engaging portions 213 and the engaging slots 12 to engage the sleeve assembly 20 with the base 10, the connection structure between the sleeve assembly 20 and the base 10 is simplified, thereby reducing production and user costs. Furthermore, it allows users to better disassemble and connect the sleeve assembly 20 and the base 10 for reuse, effectively improving user convenience.

[0030] like Figure 2 and Figure 3As shown, in an optional embodiment, the end of the extension 212 adjacent to the base 10 is adapted to be recessed inward to form a constriction 214. A sealing groove 215 communicating with the communication opening 211 is adapted to be formed between the constriction 214 and the extension 212. The sealing member 23 is at least partially confined within the sealing groove 215. The sealing groove 215 is adapted to position the installation of the sealing member 23.

Limiting the sealing member 23 through the sealing groove 215 can reduce the possibility of the sealing member 23 failing to seal properly or slipping into the food storage bag, thus effectively ensuring the connection stability and sealing stability of the sealing member 23 and improving the user experience.

[0031] like Figures 1 to 4 As shown, in an optional embodiment, the sleeve assembly 20 includes a sleeve 21 detachably fitted onto the outside of the base 10 and a cover 22 covering the sleeve 21. The cover 22 has a clearance opening 221 corresponding to and communicating with the communication port 211. The clearance opening 221 has an abutment portion 222 extending towards the base 10 around its periphery. The abutment portion 222 is adapted to abut against the sealing member 23. The abutment portion 222 is adapted to limit the sealing member 23. By limiting the sealing member 23 through the abutment portion 222, the sealing member 23 can be prevented from falling out of the sealing groove 215, thereby causing sealing failure, effectively ensuring the connection stability and sealing stability of the sealing member 23.

[0032] like Figures 1 to 5 As shown, in an optional embodiment, a fastening assembly 24 is provided between the sleeve 21 and the cover 22, and the cover 22 is adapted to be separably fastened to the sleeve 21 via the fastening assembly 24. The separable fastening of the cover 22 and the sleeve 21 via the fastening assembly 24 not only simplifies the connection structure between the cover 22 and the sleeve 21, thereby reducing the production cost and user cost of the sealing device, but also facilitates the user in separating the cover 22 and the sleeve 21 for disassembly, cleaning, and replacement of the sealing element 24, effectively ensuring the performance stability and hygiene of the sealing device.

[0033] like Figures 2 to 4As shown, in an optional embodiment, one end of the cover 22 is adapted to be hinged to the sleeve 21, and the other end is adapted to be detachably fastened to the sleeve 21 via a fastening assembly 23. By hinged one end of the cover 22 to the sleeve 21, the user can easily flip the cover 22 to separate and fasten the cover 22 from the sleeve 21, effectively improving user convenience and user experience.

[0034] like Figure 2 , Figure 3 and Figure 6 As shown, in an optional embodiment, the base 10, near the end of the sleeve assembly 20, is provided with a plurality of toothed blades 13 extending toward the sleeve assembly 20, surrounding the airflow channel 11.

By providing the toothed blades 13 at the end of the base 10 near the sleeve assembly 20, the base 10 can automatically open the wall of the food storage bag through the toothed blades 13 when fitted onto the sleeve assembly 20, facilitating vacuuming by the user and effectively improving user convenience.

[0035] like Figures 1 to 6 As shown, in an optional embodiment, the base 10 has an outwardly extending annular flange 14 at its bottom. When the sleeve assembly 20 is fitted onto the outside of the base 10, the sleeve assembly 20 is adapted to abut against the annular flange 14. The annular flange 14 is adapted to limit the installation of the sleeve assembly 20. By limiting the installation of the sleeve assembly 20 through the annular flange 14, the installation difficulty of the sleeve assembly 20 can be effectively reduced, and the user's misoperation can be avoided, which could lead to excessive fit between the sleeve assembly 20 and the base 10, thereby damaging the toothed cutter 13 and / or scratching the sleeve assembly 20, effectively improving the user experience.

[0036] like Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, in an optional embodiment, the sleeve assembly 20 and the annular flange 14 have a mating portion 25 and a mating groove 15 corresponding to the mating portion 25 on their opposing surfaces, respectively. When the sleeve assembly 20 is sleeved on the outside of the base 10, the mating portion 25 is adapted to engage with the mating groove 15. The mating portion 25 and the mating groove 15 are adapted to limit the installation of the sleeve assembly 20. By limiting the installation of the sleeve assembly 20 through the mating portion 25 and the mating groove 15, the possibility of the sleeve assembly 20 sliding freely during installation, thereby preventing loosening and falling off, can be reduced. At the same time, the mating portion 25 and the mating groove 15 are adapted to seal the connection between the sleeve assembly 20 and the base 10. By sealing the connection between the sleeve assembly 20 and the base 10 through the mating portion 25 and the mating groove 15, the sealing stability of the sealing device can be effectively guaranteed, thereby improving the performance stability of the sealing device.

[0037] like Figure 1 , Figure 4 and Figure 5 As shown, in an optional embodiment, the sleeve assembly 20 is provided with a plurality of anti-slip portions 30 at vertical intervals on its side. The anti-slip portions 30 are adapted to protrude from the outer surface of the sleeve assembly 20. The anti-slip portions 30 are adapted to provide an anti-slip function. By providing the anti-slip portions 30 on the outer surface of the sleeve assembly 20, the slippage that occurs when the user holds the sleeve assembly 20 can be reduced, allowing the user to better grip the sleeve assembly 20 for installation and disassembly, effectively improving user convenience and user experience.
