Description

Technical Field

[0001] This utility model relates to the field of vacuum preservation machine technology, and in particular to an automatic lid opening structure for a vacuum machine. Background Technology

[0002] A vacuum food preservation machine is a household or commercial appliance that uses vacuum technology to extend the shelf life of food. Its core principle is to create a low-oxygen environment by removing air (mainly oxygen) from the packaging container, thereby effectively inhibiting the growth and reproduction of microorganisms (such as bacteria and mold) that cause food spoilage, slowing down food oxidation (such as browning and fat rancidity), and reducing moisture loss.

[0003] Existing vacuum preservation machines generally consist of a body and a lid, with a flip handle on the lid. After the vacuum preservation machine has finished vacuuming and sealing, it is usually necessary to manually push the flip handle to unlock it and then lift the flip handle upwards to open the lid. Because it requires manual unlocking and opening, the practicality of the vacuum preservation machine is poor, which is not conducive to the market sales of the vacuum preservation machine. Utility Model Content

[0004] The purpose of this invention is to provide an automatic opening structure for a vacuum machine that can automatically unlock and improve its practicality.

[0005] To solve the above technical problems, the present invention can be implemented using the following technical solutions:

[0006] An automatic lid-opening structure for a vacuum machine includes a machine body, a lid, and an unlocking unit. The lid is hinged to the rear side of the machine body so that the lid can be rotated open or closed relative to the machine body. Locking slots are respectively provided on the left and right sides of the machine body. A rotating shaft is provided inside the lid, and locking tongues corresponding to the locking slots are respectively provided at both ends of the rotating shaft. The unlocking unit is installed inside the lid and is connected to the rotating shaft for transmission. The unlocking unit can drive the rotating shaft to rotate so as to rotate the locking tongue into the locking slot or rotate the locking tongue out of the locking slot.

[0007] In one embodiment, the unlocking unit includes a driving member, an active tooth, and a driven tooth. The active tooth is connected to the output end of the driving member, and the driven tooth is mounted on the rotating shaft and meshes with the active tooth. When the driving member drives the active tooth to rotate, the driven tooth will rotate the rotating shaft.

[0008] In one embodiment, the latch includes an integrally formed main body, a sleeve, and a locking hook. The sleeve is located on one side of the main body and is interference-fitted to the end of the pivot. The locking hook extends along the lower part of the main body and is bent.

[0009] In one embodiment, the cover is provided with a positioning part adapted to the lock groove, the lock hook part is located inside the positioning part, and a through hole is provided on the side wall of the positioning part for the lock hook part to pass through.

[0027] Please see Figures 1 to 3 An automatic opening structure for a vacuum machine includes a body 100, a cover 200, and an unlocking unit 300. The cover 200 is hinged to the rear side of the body 100 so that the cover 200 can be rotated open or closed relative to the body 100. Locking grooves 110 are respectively provided on the left and right sides of the body 100. A rotating shaft 210 is provided inside the cover 200. Locking tongues 220 corresponding to the locking grooves 110 are respectively provided at both ends of the rotating shaft 210. The unlocking unit 300 is installed inside the cover 200 and is connected to the rotating shaft 210 for transmission. The unlocking unit 300 can drive the rotating shaft 210 to rotate so as to rotate the locking tongues 220 into or out of the locking grooves 110.

[0028] Specifically, in this embodiment, a vacuum chamber is provided on the body of the vacuum machine. During vacuuming, the opening of a vacuum packaging bag or similar bag is inserted into the vacuum chamber. After the vacuum pump connected to the vacuum chamber is started, the vacuum packaging bag or similar bag is vacuumed through the vacuum chamber. Finally, the opening of the bag is heat-sealed by the heating component to complete the sealing action. After vacuuming and sealing are completed, the control system will start the unlocking unit 300, which will drive the rotating shaft 210 to rotate. When the rotating shaft 210 rotates, it will rotate the locking tongues 220 at both ends, so that the locking tongues 220 at both ends will rotate out of the locking grooves 110 on the left and right sides of the machine body 100, thereby realizing the automatic unlocking of the locking tongues 220. After unlocking, the cover 200 can be opened directly. By using the unlocking unit 300 to automatically unlock instead of manual unlocking, the practicality of the vacuum machine can be improved, and the humanized concept of the vacuum machine product can be enhanced, thus providing opportunities for the vacuum machine product to expand the market and increase market sales.

[0029] Furthermore, to further enhance the practicality of the vacuum machine, the rear side of the cover 200 and the rear side of the body 100 can be hinged using a hinge with a torsion spring. When the unlocking unit 300 drives the rotating shaft 210 to rotate the locking tongues 220 at both ends out of the locking groove 110 to achieve automatic unlocking, the cover 200 can automatically spring open through the hinge with the torsion spring, thereby opening the cover 200 and the body 100 at a set angle. The automatic opening of the cover 200 serves as a reminder to the user that vacuuming and sealing have been completed and the cover can be opened, thus improving the practicality of the vacuum machine. It should be noted that the hinge with the torsion spring is existing technology and will not be elaborated upon here.

[0030] Please see Figure 2 or Figure 3 In order to achieve automatic unlocking, the unlocking unit 300 in this embodiment includes a driving member 310, an active tooth 320 and a driven tooth 330. The active tooth 320 is connected to the output end of the driving member 310, and the driven tooth 330 is mounted on the rotating shaft 210 and meshes with the active tooth 320. When the driving member 310 drives the active tooth 320 to rotate, the driven tooth 330 will drive the rotating shaft 210 to rotate.

[0031] After vacuuming and sealing are completed, the control unit will start the drive unit 310. The drive unit 310 can be a geared motor. The drive unit 310 will drive the active gear 320 at the output end to rotate. Since the driven gear 330 is installed on the rotating shaft 210 and meshes with the active gear 320, the driven gear 330 will rotate accordingly. When the driven gear 330 rotates, it will drive the rotating shaft 210 to rotate, thereby rotating the locking tongues 220 at both ends of the rotating shaft 210 out of the locking groove 110, thereby realizing the automatic unlocking of the cover 200.

[0032] It should be noted that the unlocking unit 300 can also use other structures to drive the rotating shaft 210 to rotate, such as belt drive connection, sprocket drive connection, etc. The specific structure is not limited, as long as the unlocking unit 300 can drive the rotating shaft 210 to rotate.

[0033] Please see Figure 3 and Figure 4 In order to lock the cover 200 to the body 100, the locking tongue 220 in this embodiment includes an integrally formed main body 221, a sleeve 222 and a locking hook 223. The sleeve 222 is located on one side of the main body 221 and is interference-fitted to the end of the rotating shaft 210. The locking hook 223 extends along the lower part of the main body 221 and is bent. At the same time, the cover 200 is provided with a positioning part 230 that is adapted to the locking groove 110. The locking hook 223 is located in the positioning part 230, and a through hole 231 for the locking hook 223 to pass through is provided on the side wall of the positioning part 230.

[0034] By adapting the positioning part 230 to the locking groove 110, the cover 200 is positioned when closed with the body 100, thereby ensuring that the locking tongue 220 of the cover 200 can be accurately locked into the locking groove 110 of the body 100, thus locking the cover 200 and the body 100. In addition, the sleeve part 222 is set on one side of the main body part 221, which can facilitate the sleeve part 222 to be sleeved with the end of the rotating shaft 210. The sleeve can be interference fit, or a fixing glue can be applied after the sleeve is sleeved, so that the connection between the locking tongue 220 and the rotating shaft 210 is stable, and the locking tongue 220 can rotate with the rotating shaft 210 to unlock. The downward extension and bending of the locking hook part 223 can be easily inserted into the locking groove 110 to realize the locking function.

[0035] Please see Figure 2 After the locking tongue 220 automatically unlocks from the locking groove 110, a flip handle 240 is provided above the cover 200 to facilitate flipping it open. This flip handle 240 is connected to the rotating shaft 210. After unlocking, the user can flip the cover 200 open using the flip handle 240, and can also easily flip the cover 200 closed. In addition, when the unlocking unit 300 malfunctions, the rotating shaft 210 can also be rotated using the flip handle 240 to achieve manual unlocking, thereby improving the practicality of the vacuum machine product.

[0036] Finally, please see Figure 2 or Figure 3To ensure the overall structural stability of the opening mechanism, the rotating shaft 210 is square in shape with a square cross-section. In this embodiment, the rotating shaft 210 is preferably quadrilateral. The quadrilateral shape facilitates the installation of the driven gear 330 onto the rotating shaft 210 and ensures that the rotating shaft 210 can rotate with the driven gear 330, thus avoiding the situation where the driven gear 330 rotates while the rotating shaft 210 remains stationary. Of course, the rotating shaft 210 can also adopt a triangular or other irregular shape, which is not limited here, as long as it can drive the rotating shaft 210 to rotate when the driven gear 330 rotates.

[0037] Meanwhile, in order to ensure the connection stability between the driving tooth 320 and the driven tooth 330, the driving member 310 can be fixed inside the cover 200 by the first limiting member 250, and the sleeve part 222 of the locking tongue 220 can be fixed inside the cover 200 by the second limiting member 260. This can achieve the positioning of the rotating shaft 210, so as to avoid the driving member 310 carrying the driving tooth 320 or the rotating shaft 210 carrying the driven tooth 330 from shifting, thereby ensuring the meshing connection stability between the driving tooth 320 and the driven tooth 330.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description; however, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model; furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
