Specific embodiments

[0025] The following describes the specific embodiments of the present utility model with reference to the accompanying drawings. To fully understand the present utility model, many details are described below, but for those skilled in the art, the present utility model can be implemented without these details.

[0026] As Figures 1 to 4 shown, the present utility model provides a vacuum fresh-keeping machine, including a body 1, a machine cover 2 and at least one hinge member 3. A mounting boss 11 is provided on one side of the body 1. The mounting boss 11 is provided with a cavity for arranging circuits, and an operation button 111 is provided on the tabletop of the mounting boss 11; the machine cover 2 is rotatably arranged on the mounting boss 11 through the hinge member 3. The present utility model is provided with a mounting boss 11 on one side of the body 1. The mounting boss 11 can not only be used for arranging circuits and setting the operation button 111, but also for mounting the machine cover 2, thus ingeniously solving the problem of insufficient layout space of the body 1 and the need to only arrange circuits and set the operation button 111 on the machine cover 2, making the circuit layout of the vacuum fresh-keeping machine more reasonable and the overall design more flexible.

[0027] As Figures 3 to 6 shown, the mounting boss 11 is provided with a mounting groove 112; the hinge member 3 includes a hinge plate 31 and a first connecting portion 32 and a second connecting portion 33 arranged at both ends of the hinge plate 31. The first connecting portion 32 is fixedly connected to the machine cover 2, and the second connecting portion 33 is hinged in the mounting groove 112; when the machine cover 2 is closed, the hinge plate 31 is received in the mounting groove 112, and when the machine cover 2 is opened, the hinge plate 31 is flipped out of the mounting groove 112. Such a design can ensure that the flipping movement of the machine cover 2 is not blocked by the mounting boss 11, and can ensure that the closed machine cover 2 is flush with the mounting boss 11, thereby improving the overall aesthetics of the vacuum fresh-keeping machine. As a preferred solution: the hinge plate 31 is an arc-shaped hinge plate.

[0028] As Figures 3 to 6As shown in the figure, specifically, a relief groove 21 is provided on one side of the machine cover 2, and the first connecting portion 32 is embedded in the relief groove 21, thereby realizing the hidden installation of the first connecting portion 32. A rotating shaft 113 is installed in the installation groove 112, and the second connecting portion 33 is provided with a shaft hole 331 that cooperates with the rotating shaft 113, thereby hinging the machine cover 2 to the installation boss 11 to ensure that the machine cover 2 can be flipped smoothly.

[0029] As Figures 3 to 6 shown in the figure, the hinge plate 31 includes a hinge plate body 311 and a cover plate 312. A plurality of reinforcing ribs 313 are provided on the outer side wall of the hinge plate body 311, and the cover plate 312 is detachably arranged on the hinge plate body 311 for covering the reinforcing ribs 313. Such a design can effectively improve the structural strength of the hinge plate 31 on the one hand, ensuring that the overall structure of the vacuum fresh-keeping machine is more firm and reliable, and on the other hand, the cover plate 312 can cover the reinforcing ribs 313, making the external structure of the hinge plate 31 more beautiful and grand. In order to further strengthen the overall structure of the hinge 3, a plurality of reinforcing ribs 313 are also provided on the outer side wall of the second connecting portion 33 in this embodiment. However, since the second connecting portion 33 is always located in the installation groove 112 and is not exposed when the machine cover 2 is flipped, there is no need to provide a cover plate 312 for covering the reinforcing ribs 313.

[0030] As Figures 1 to 4 shown in the figure, the vacuum fresh-keeping machine further includes a baffle 4. The baffle 4 is interlocked with the hinge 3 and is used to close the installation groove 112 when the machine cover 2 is opened. The purpose of setting the baffle 4 is as follows: First, the baffle 4 can close the installation groove 112 when the machine cover 2 is opened, so it can improve the overall aesthetics of the vacuum fresh-keeping machine and prevent the structure in the installation groove 112 from being exposed and affecting the visual effect; Second, since the installation groove 112 communicates with the cavity for arranging wires, if the installation groove 112 is exposed, there will be certain potential safety hazards. Therefore, closing the installation groove 112 through the baffle 4 can improve the safety performance of the vacuum fresh-keeping machine and make it meet the safety performance requirements of the UL safety standard test.

[0031] As Figures 1 to 6 shown in the figure, as a specific installation method: one end of the baffle 4 is rotatably arranged in the installation groove 112 through a rotating shaft 41 and a return spring (not shown in the figure), and the other end of the baffle 4 abuts against the hinge 3. When the machine cover 2 is closed, the baffle 4 is pushed by the hinge 3 and flips into the installation groove 112. When the machine cover 2 is opened, the thrust received by the baffle 4 disappears, and under the action of the return spring, it flips towards the notch of the installation groove 112 and abuts against the hinge plate 31 to close the installation groove 112. A limit block 42 is provided at the other end of the baffle 4, and the second connecting portion 33 is provided with a relief recess 332 that cooperates with the limit block 42, thereby restricting the flipping angle of the baffle 4 and making its cooperation with the hinge 3 more tight and reliable.

[0032] AsFigure 1 and Figure 2 As shown in Figure 2 , preferably, the number of the hinge members 3 in this embodiment is one. An installation groove 112 for installing the hinge member 3 is provided in the middle of the installation boss 11, and operation buttons 111 are provided on the table surfaces on both sides of the installation boss 11. Since the hinge member 3 provided in this embodiment has a firm and reliable structure, only one hinge member 3 is needed to realize the stable connection between the machine cover 2 and the machine body 1, thereby avoiding occupying the layout space of the installation boss 11. Of course, in practical applications, the number of the hinge members 3 and the position of the installation groove 112 can also be flexibly adjusted according to requirements.

[0033] The above is only the specific implementation manner of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantive modification of the present utility model using this concept shall fall within the scope of infringement of the protection scope of the present utility model.
