Description

Technical Field

[0001] This utility model relates to the field of micro vacuum packaging machine technology, and in particular to a foldable micro vacuum packaging machine. Background Technology

[0002] A miniature vacuum sealer is a small household device that creates a vacuum environment by extracting air from a packaging bag and then heat-sealing the bag. It is mainly used to extend the shelf life of food. Its core components include a miniature vacuum pump, a heated sealing strip, and an intelligent control panel. It is suitable for use in home kitchens, outdoor picnics, or small shops, and can effectively block oxygen and moisture, inhibiting bacterial growth.

[0003] To meet portability requirements, existing miniature vacuum sealing machines are designed to be relatively small in overall size. However, their shell structure is usually composed of a rigid upper and lower cover that are fixedly connected, housing components such as vacuum pumps, sealing strips, and control units. While this integrated rigid structure can ensure the structural strength and sealing effect of the machine during operation, its fixed shape still occupies a large space when not in use. In particular, its length and width are difficult to compress, which limits its convenience of storage and carrying. It cannot meet users' needs for ultimate portability, especially when users need to put it into the small space of a handbag or suitcase. The volume limitation caused by this fixed shape is particularly obvious and not conducive to use.

[0004] Therefore, those skilled in the art have provided a foldable micro vacuum packaging machine to solve the problems mentioned in the background art. Utility Model Content

A locking rod is fixedly connected to both sides of the elastic sheet. A locking frame is provided on the front side of the elastic sheet. Both sides of the rear side of the locking frame extend into the inner cavity of the locking shell. The side of the locking rod away from the elastic sheet extends into the inner cavity of the locking frame.

[0008] By adopting the above technical solution, the upper and lower housings can be folded and stored together in cooperation with the lower housing and the pivot, reducing storage space. The locking mechanism can lock the two lower housings for easy vacuum sealing. The miniature vacuum pump can extract air from the packaging bag. The locking shell can cooperate with the card frame to limit the two lower housings. The elastic sheet can control the insertion of the card rod into the card frame, thereby locking the two lower housings. After assembly, vacuum sealing can be performed. After folding, its portability can be improved.

[0009] Optionally, the card frame has card slots on both sides of its inner cavity for use with the card rod, and the top of the card frame is fixedly connected to one of the lower housings by an elastic rope.

[0010] By adopting the above technical solution, the card slot can cooperate with the card rod to connect the two locking shells to the card frame, thereby increasing the stability of the connection and fixation of the two lower housings.

[0011] Optionally, both sides of the inner cavity of the elastic sheet are fixedly connected to a lever, and the side of the lever away from the elastic sheet is provided with an inclined slope.

[0012] By adopting the above technical solution, the user can easily control the retraction of the two elastic plates by setting a lever, which is used to control the position of the lever.

[0013] Optionally, a fixed magnetic sheet is fixedly connected to the top of the upper housing, and the magnetic poles of the two fixed magnetic sheets on opposite sides are opposite.

[0014] By adopting the above technical solution, the two upper housings can be locked together after being closed by setting a fixed magnetic sheet, preventing them from being accidentally opened.

[0015] Optionally, a control panel is fixedly connected to the top of the upper housing, and a support block is fixedly connected to the bottom of the lower housing.

[0016] By adopting the above technical solution, the control panel allows users to easily operate the entire device, and the support block provides stable support for the lower casing.

[0017] Optionally, a maintenance plate is provided on the rear side of the lower housing, and the front side of the maintenance plate is fixedly connected to the lower housing by screws.

[0018] By adopting the above technical solution, the maintenance plate facilitates the user's maintenance of the components installed inside the lower housing, and the screws facilitate the installation and removal of the maintenance plate.

[0019] Optionally, a battery is fixedly connected to the inner wall of the lower housing, and through holes for use with the locking rod are provided on the opposite sides of the two locking housings.

[0020] By adopting the above technical solution, the battery can store electricity, which facilitates the normal operation of the micro vacuum pump, and the through hole makes it easy for the clamp rod to be inserted into the inner cavity of the clamp slot.

[0021] In summary, this utility model has the following beneficial effects:

[0022] 1. This utility model achieves the folding operation of the entire device by means of a pivot connecting the upper and lower housings. After folding, the volume is reduced, making it easy to store and carry. It can be placed in a small bag or suitcase. The fixing magnetic sheet ensures that the folded state is stable and locked to prevent accidental unfolding. During use, you only need to unfold it flat to perform vacuum sealing.

[0023] 2. This utility model uses a locking mechanism that utilizes a slot in the inner cavity of the card frame to cooperate with the card rod. When the card rod is inserted into the card frame, it locks the two lower housings, ensuring that the lower housings are stably assembled, facilitating vacuum sealing operations, preventing folding during vacuum sealing, and improving the stability of vacuum sealing operations.

A miniature vacuum pump 4 is fixedly connected to the bottom of the inner cavity of the lower housing 2. An air inlet on one side of the miniature vacuum pump 4 extends into the air extraction port of the lower housing 2. A locking mechanism 5 is fixedly connected to the bottom of the lower housing 2. The locking mechanism 5 includes a locking shell 51. The top of the locking shell 51 is fixedly connected to the lower housing 2. An elastic sheet 52 is provided between the two locking shells 51. A locking rod 53 is fixedly connected to both sides of the elastic sheet 52. A locking frame 54 is provided on the front side of the elastic sheet 52. Both sides of the rear side of the locking frame 54 extend into the inner cavity of the locking shell 51. The side of the locking rod 53 away from the elastic sheet 52 extends into the inner cavity of the locking frame 54.

[0034] In this embodiment: by setting the upper housing 1 to cooperate with the lower housing 2 and the rotating shaft 3 to realize the folding and storage operation of the upper housing 1 and the lower housing 2, the storage space is reduced by folding. The locking mechanism 5 can lock the two lower housings 2 to facilitate vacuum sealing. The micro vacuum pump 4 can extract the air from the packaging bag. The locking shell 51 can cooperate with the card frame 54 to limit the two lower housings 2. The elastic sheet 52 can control the card rod 53 to insert into the inside of the card frame 54, thereby locking the two lower housings 2. After the assembly is completed, the vacuum sealing operation can be performed. After folding, its portability can be improved.

[0035] Example 2:

[0036] Reference Figure 1-5 Both sides of the inner cavity of the card frame 54 are provided with card slots that cooperate with the card lever 53. The top of the card frame 54 is fixedly connected to one of the lower housings 2 by an elastic rope. Both sides of the inner cavity of the elastic sheet 52 are fixedly connected with a lever. The side of the card lever 53 away from the elastic sheet 52 is provided with an inclined slope. The top of the upper housing 1 is fixedly connected with a fixing magnetic sheet 6. The magnetic poles of the two fixing magnetic sheets 6 on opposite sides are opposite. The top of the upper housing 1 is fixedly connected with a control panel 7. The bottom of the lower housing 2 is fixedly connected with a support block 8. A maintenance plate 9 is provided on the rear side of the lower housing 2. The front side of the maintenance plate 9 is fixedly connected to the lower housing 2 by screws. The inner wall of the lower housing 2 is fixedly connected with a battery 10. Both sides of the two locking shells 51 are provided with through holes that cooperate with the card lever 53.

[0037] In this embodiment: by setting a slot, the two locking shells 51 can be connected to the frame 54 in cooperation with the locking rod 53, increasing the stability of the connection between the two lower housings 2; by setting a lever, the user can easily control the retraction of the two elastic pieces 52 to control the position of the locking rod 53; by setting a fixing magnet 6, the two upper housings 1 can be locked after closing to prevent them from being accidentally opened; by setting a control panel 7, the user can easily operate the entire device; the support block 8 can provide stable support for the lower housing 2; by setting a maintenance plate 9, the user can easily maintain the components installed inside the lower housing 2; by setting screws, the maintenance plate 9 can be easily installed and removed; by setting a battery 10, power can be stored to facilitate the normal operation of the micro vacuum pump 4; and by setting a through hole, the locking rod 53 can be easily inserted into the inner cavity of the slot.

[0038] The implementation principle of this utility model is as follows: When in use, first unfold the device and place the two lower housings 2 flat on the table. At this time, the support block 8 provides stable support. Then, place the opening of the packaging bag to be sealed in the air extraction port area between the upper housing 1 and the lower housing 2. The packaging bag is vacuum sealed by the micro vacuum pump 4. After use, the elastic piece 52 can be retracted by the lever, so that the locking rod 53 is disengaged from the inner cavity of the locking slot. After the locking frame 54 is pulled out, the upper housing 1 and the lower housing 2 are folded so that the two upper housings 1 are closed together. At the same time, the two fixing magnetic pieces 6 attract each other to prevent the two upper housings 1 from being accidentally unfolded. After the two upper housings 1 are closed by the pivot 3, the space occupied is reduced, so that they can exist in some narrow areas, making it convenient for users to carry and improving its portability. When it is necessary to continue to use it for vacuum sealing, the above steps are reversed to unfold it and vacuum seal the packaging bag.

[0039] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
