Description

Technical Field

[0001] This utility model relates to the field of sealing machines, specifically a multi-functional sealing machine. Background Technology

[0002] Currently, the sealing machine structure is similar to that described in Chinese patent document CN202421037027.3, which discloses a vacuum sealing machine with an external air extraction port. This vacuum sealing machine primarily discloses that it includes an external air extraction port that is movably connected to the cover. The cover has an air path switching mechanism corresponding to the movement trajectory of the external air extraction port. When the external air extraction port moves, the state of the air path switching mechanism changes, allowing the external air extraction port to selectively connect with the suction port of the vacuum pump. This structure, by rotating the external air extraction port, cuts off the connection between the external air extraction port and the vacuum pump. The connection between the air pump's suction port or the vacuum chamber ensures that the sealing machine only evacuates air from the vacuum chamber and does not draw air in from the external suction port, which could lead to vacuum failure. Furthermore, the addition of isolation and connection indicators allows users to determine the sealing machine's operating status. However, during use, the air path switching mechanism is prone to misalignment or damage to the sealing structure, resulting in air leakage from the external suction port. Therefore, this applicant provides a new solution that also achieves the same method of cutting off the external suction port and providing operating status alerts for consumers to choose from. Utility Model Content

[0003] The purpose of this invention is to solve the aforementioned problems and provide a simple and reasonable multi-functional sealing machine. Its main function is to use an elastic sealing plug to indicate the working status and perform pressure relief operations.

[0004] A multifunctional sealing machine includes a cover and a base that open and close together, with the cover and base together enclosing a vacuum chamber. The cover contains a vacuum pump that communicates with the vacuum chamber and a main control board that is electrically connected to the vacuum pump. The cover also has an external vacuum interface that communicates with the vacuum chamber. An interface cover is detachably connected to the external vacuum interface. The interface cover has an installation opening, and an elastic sealing plug is tightly installed in the installation opening. The elastic sealing plug has an elastic film that deforms with air pressure.

[0005] The objective of this utility model can also be achieved by the following technical measures:

[0006] As a more specific solution, a connecting strip is provided between the interface cover and the cover body.

[0007] As a further embodiment, the interface cover includes a cover surface and a sealing sleeve. The bottom surface of the cover surface extends with an annular wall that is embedded in the external pull-out interface. The installation opening is located at the center of the cover surface. The sealing sleeve is fitted onto the outer wall of the annular wall and has a connecting strip integrally formed on the sealing sleeve.

[0008] As a further embodiment, the elastic sealing plug includes a plug sleeve that fits tightly with the installation opening. One end of the plug sleeve extends to have an inner plug ring and an outer plug ring that abut against the inner and outer sides of the interface cover, respectively. The plug sleeve is engaged in the installation opening by the inner plug ring and the outer plug ring. The elastic film is integrally disposed at the port of the plug sleeve. The elastic film has an arc-shaped structure.

[0009] As a further embodiment, a cover-closing induction switch electrically connected to the main control board is installed inside the cover corresponding to the external pull-out interface. The interface cover is provided with a first sensing element or sensing part. When the interface cover is in place at the installation opening, the sensing element or sensing part triggers the cover-closing induction switch.

[0010] As a further embodiment, a pressure sensor is electrically connected to the main control board, and the pressure sensor is connected to the vacuum chamber through a sensing air path; the main control board is provided with a pressure value display structure that is linked to the pressure sensor; the pressure value display structure includes a display screen or several arranged LED beads.

[0011] As a further solution, the cover is also equipped with a power switch and function keys for controlling the main control board. The function keys can be pressed to switch between two or more of the following modes: dry extraction mode, wet extraction mode, sealing mode, and external extraction mode.

[0012] As a further embodiment, a sealing assembly and a sealing ring are provided between the cover and the base; the sealing assembly includes at least an elongated heating module and a pressure strip, the elongated heating module is fixed to the bottom surface of the cover, the pressure strip and the sealing ring are fixed to the top surface of the base, and the pressure strip corresponds to the elongated heating module; the sealing ring surrounds the outer periphery of the pressure strip and abuts against the bottom surface of the cover to jointly form a vacuum chamber.

[0013] As a further embodiment, the cover contains a rechargeable battery pack electrically connected to the main control board, and the cover also has a charging port electrically connected to the main control board.

[0014] As a further embodiment, the cover body is provided with a first magnet block at a fixed position corresponding to the interface cover, and the interface cover is provided with a second magnet block that cooperates with the first magnet block;

[0015] The cover is equipped with an opening induction switch that is electrically connected to the main control board. The interface cover is provided with a second sensing element.

[0016] This utility model discloses a multi-functional sealing machine. This sealing machine can vacuum other containers with bottle openings through an external suction interface, realizing the multi-functional function of the sealing machine and improving its practicality.

[0017] On the other hand, during normal use, the expansion or contraction of the elastic film allows users to determine whether the sealing machine is in operation, making the observation method more intuitive and simple.

[0018] Furthermore, after the sealing machine has finished sealing, the user only needs to flatten the elastic sealing plug to create a gap between the elastic sealing plug and the installation opening. Air then enters the vacuum chamber through the gap and the external suction port, thus achieving the pressure relief operation of the vacuum chamber. The structure is simple and the operation is easy, eliminating the need for the traditional complex pressure relief structure. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0028] like Figures 1 to 6 As shown, a multi-functional sealing machine includes a cover 1 and a base 2 that open and close together. The cover 1 and the base 2 together enclose a vacuum chamber A. The cover 1 is equipped with a vacuum pump 3 that communicates with the vacuum chamber A, and a main control board 4 that is electrically connected to the vacuum pump 3. The cover 1 is also equipped with an external vacuum interface 5 that communicates with the vacuum chamber A. An interface cover 6 is detachably connected to the external vacuum interface 5. The interface cover 6 has an installation opening 601, and an elastic sealing plug 7 is tightly installed in the installation opening 601. The elastic sealing plug 7 is equipped with an elastic film 8 that deforms with air pressure.

[0029] Compared with existing technologies, this sealing machine has the advantage of being able to vacuum other containers with bottle openings through the external suction interface 5, thus achieving a multi-functional function and improving its practicality.

[0030] On the other hand, during normal use, the expansion or contraction of the elastic film 8 allows users to determine whether the sealing machine is in operation, making the observation method more intuitive and simple.

[0031] Furthermore, after the sealing machine has finished sealing, the user only needs to pinch the elastic sealing plug 7 to create a gap between the elastic sealing plug 7 and the installation opening 601. Air then enters the vacuum chamber A through the gap and the external suction port 5, thus realizing the pressure relief operation of the vacuum chamber A. The structure is simple and the operation is easy, eliminating the need for the traditional complex pressure relief structure.

[0032] In this embodiment, the external extraction interface 5 is defined by a bell jar structure, and a connecting pipe 51 extends rearward from the center of the bell jar structure. The connecting pipe 51 is connected to the first external interface A1 of the vacuum chamber A through the pipe body.

[0033] A connecting strap 9 is provided between the interface cover 6 and the cover body 1; after the interface cover 6 is removed and the external pull-out interface 5 is opened, the interface cover 6 can be hung on the cover body 1 to prevent the interface cover 6 from falling off.

[0034] The interface cover 6 includes a cover surface 61 and a sealing sleeve 62. The bottom surface of the cover surface 61 extends into an annular wall 63 that is embedded in the external pull-out interface 5. The installation opening 601 is opened at the center of the cover surface 61. The sealing sleeve 62 is sleeved on the outer wall of the annular wall 63, and a connecting strip 9 is integrally formed on the sealing sleeve 62.

[0035] The sealing sleeve 62 includes a circular sleeve portion 621, which abuts against the outer wall surface of the annular wall 63 and the inner wall surface of the external pull-out interface 5 after the interface cover 6 is installed in place. The circular sleeve portion 621 also extends outward with a flange portion 622. Similarly, after the interface cover 6 is installed in place, the flange portion 622 abuts against the inner wall surface of the cover surface 61 and the edge of the external pull-out interface 5. This structure of the sealing sleeve 62 can improve the sealing effect. Moreover, the connecting strip 9 and the sealing sleeve 62 are integrally formed, which reduces production costs and improves assembly efficiency. Furthermore, the connecting strip 9 is made of the same elastic material (such as silicone) as the sealing sleeve 62, which increases the service life of the connecting strip 9.

[0036] The elastic sealing plug 7 includes a plug sleeve 71 that fits tightly with the installation opening 601. One end of the plug sleeve 71 extends to have an inner plug ring 72 and an outer plug ring 73 that abut against the inner and outer sides of the interface cover 6, respectively. The plug sleeve 71 is engaged in the installation opening 601 by the inner plug ring 72 and the outer plug ring 73. The elastic film 8 is integrally disposed at the port of the plug sleeve 71. The elastic film 8 has an arc-shaped structure. When the elastic sealing plug 7 with this structure is in use, under normal conditions, the outer suction interface 5 is in a normal pressure state, and the elastic film 8 bulges outward. Moreover, when the sealing machine is vacuumed, the outer suction interface 5 forms a negative pressure, which causes the elastic film 8 to contract inward, allowing the user to quickly determine that the sealing machine is in working condition and not to directly open the cover 1.

[0037] The main control board 4 is electrically connected to a pressure sensor 10, which is connected to the vacuum chamber A through a sensing gas path. The main control board 4 is equipped with a display screen 11 that is linked to the pressure sensor 10. The vacuum chamber A is equipped with a second external interface A2, and the pressure sensor 10 is connected to the second external interface A2 through a pipe. The air pressure value of the vacuum chamber A is then directly displayed on the display screen 11, making it easy for the user to perceive the degree of vacuuming.

[0038] In other embodiments, the display screen 11 may be replaced by a plurality of arranged LED beads.

[0039] The cover 1 is also provided with a power switch 12 and a function key 13 for controlling the main control board 4. The function key 13 can be pressed to switch between two or more of the following modes: dry extraction mode, wet extraction mode, sealing mode and external extraction mode.

[0040] In this embodiment, the machine can be turned on or off by pressing and holding the power button 12 (for a duration of 1.5 seconds). After the sealing machine is powered on, various functions can be switched using the function key 13. For example, in dry vacuum mode, the vacuum chamber is in a vacuum or near-vacuum state before directly heat-sealing the packaging bag. In wet vacuum mode, after the pressure reaches the set pressure value, the vacuum continues for a certain period of time (for example, 30 seconds) to remove water and prevent the liquid from affecting the temperature of the heating and sealing position of the packaging bag, thus avoiding failure to seal. In sealing mode, the vacuuming operation is omitted, and the packaging bag is directly sealed. Finally, in external vacuum mode, after the interface cover 6 is determined to be open, the vacuuming is performed directly, eliminating the heat-sealing operation.

[0041] A sealing assembly and a sealing ring 14 are provided between the cover 1 and the base 2. The sealing assembly includes at least an elongated heating module 15 and a pressure strip 16. The elongated heating module 15 is fixed to the bottom surface of the cover 1, and the pressure strip 16 and the sealing ring 14 are fixed to the top surface of the base 2. The pressure strip 16 corresponds to the elongated heating module 15. The sealing ring 14 surrounds the pressure strip 16 and abuts against the bottom surface of the cover 1 to jointly form a vacuum chamber A. The structure and principle of this sealing assembly are existing technologies and will not be described in detail here.

[0042] The cover 1 is equipped with a rechargeable battery pack 17 that is electrically connected to the main control board 4. The cover 1 is also equipped with a charging port 18 that is electrically connected to the main control board 4. This structure uses the rechargeable battery pack 17 to make the cover portable. In addition, a hanging strap 21 is connected to one end of the cover 1, which helps users to carry it when they go out. Example

[0043] like Figure 7 As shown, a lid-closing induction switch electrically connected to the main control board 4 is installed inside the cover 1 at the external drawer interface 5. The interface cover 6 is provided with a first sensing element or sensing part. When the interface cover 6 is closed in the installation opening 601, the sensing element or sensing part triggers the lid-closing induction switch. In the second embodiment, the lid-closing induction switch can be a Hall switch 22, and the first sensing element is a magnet 23. Through the cooperation of the Hall switch 22 and the magnet 23, it is ensured that the sealing machine can start the dry drawer mode or wet drawer mode after the interface cover 6 is closed in place. Example

[0044] Example 3 can be supplemented based on Example 1 or Example 2, specifically as follows: Figure 8 As shown, the cover 1 is provided with a first magnet 19 at the fixed position corresponding to the interface cover 6, and the interface cover 6 is provided with a second magnet 20 that cooperates with the first magnet 19; after the interface cover 6 is disassembled and the external pull interface 5 is opened, the interface cover 6 can be adsorbed and fixed on the side wall of the cover 1 to prevent the interface cover 6 from shaking back and forth and interfering with the external pull operation.

[0045] In addition, an opening induction switch electrically connected to the main control board 4 is installed inside the cover 1. A second sensing element is provided on the interface cover 6. When the interface cover 6 is removed and magnetically attached to a fixed position, the second sensing element triggers the opening induction switch.

[0046] In this embodiment, the cover opening sensor switch can be a reed switch 24 or a Hall switch, and the second sensing element can be a second magnet 20. After the interface cover 6 is attached to the fixed position, the second magnet 20 triggers the reed switch 24 or the Hall switch, thereby ensuring that after the interface cover 6 is removed and fixed in place, the sealing machine can only start the sealing mode or the external extraction mode.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
