Referring to
With the above-mentioned structure, the multifunction vacuum package machine can be applied on both internal vacuum suction and external vacuum suction. In order to perform internal vacuum suction, a vacuum package may be placed in the lower chamber 11 in such a manner that the opening of the vacuum package gets close to the heater 41 and is located outside the lower chamber 11. When the lower chamber 11 is closed by the top lid 2, the pressing strip 42 may come into contact with the heater 41 as the rotation of the top lid 2, such that the vacuum package can be fixed by the pressing strip 42 together with the heater 41. When the vacuum pump set 3 is activated, due to the suction of the vacuum pump set 3, the gas inside the lower chamber 11 may be gradually decreased and the vacuum degree of the lower chamber 11 may be gradually increased. Once the vacuum degree of the lower chamber 11 reaches the specified value, the vacuum pump set 3 may be turned off and the heating system 4 may be activated, such that the heater 41 may heat the vacuum package, to enable the vacuum package to finish the heat-sealing. After that, the lower chamber 11 may be opened by the top lid 2 to let air in. In such a case, the vacuum package may wrinkle due to the pressure difference between inside and outside of the package, whereby the internal vacuum suction can be finished. In order to perform external vacuum suction, a specially-made vacuum package for external vacuum suction may be prepared and disposed outside the lower chamber 11, with the opening of the vacuum package being located in the lower chamber 11 and positioned close to the heater 41. When the lower chamber 11 is closed by the top lid 2, the pressing strip 42 may come into contact with the heater 41 as the rotation of the top lid 2, such that the vacuum package for external vacuum suction can be fixed by the pressing strip 42 together with the heater 41. When the vacuum pump set 3 is activated, the gas inside the vacuum package for external vacuum suction may be draw out and the pressure inside the vacuum package for external vacuum suction may be gradually decreased. In such a case, the vacuum package for external vacuum suction may wrinkle due to the pressure difference between inside and outside of the package. Then, the vacuum pump set 3 may be turned off when the vacuum package for external vacuum suction wrinkle to an extent. After that, the heater 41 may be activated to heat-seal the vacuum package, to enable the vacuum package to finish external vacuum suction. In the embodiment, the heater 41 and the pressing strip 42 of the heating system 4 are arranged outside the vacuum chamber and do not take up the space of the vacuum chamber, thereby avoiding waste of space in the conventional device. It ensures the suction effect with reduced volume of the vacuum chamber. As the volume of the vacuum chamber is reduced, the requirement on the power of vacuum pump set 3 may be lowered and thus the cost may be lowered. In addition, the distances from the edge of the vacuum package machine to the heater 41 and to the pressing strip 42 are reduced, which facilitates external vacuum suction of the vacuum package. Hence, the multifunction vacuum package machine can be applied on both internal vacuum suction and external vacuum suction and has greatly improved practicability. The multifunction vacuum package machine, which may perform both internal vacuum suction and external vacuum suction with low cost, is convenient to use and easy to popularize.
It should be noted that, the heater 41 and the pressing strip 42 may be arranged at other positions. For example, the heater 41 may be arranged on the top lid 2 and meanwhile the pressing strip 42 matched with the heater 41 may be arranged on the base 1. Such change in positions of the heater 41 and the pressing strip 42 has similar advantages.
Further, in some embodiments of the disclosure, the vacuum pump set 3 and the control system 6 are arranged on the base 1 and beside the lower chamber 11. In such a case, the height of the base may be lowered due to the changed locations of the vacuum pump set 3 and the control system 6, thereby further improving comfort during external vacuum suction, facilitating operations of external vacuum suction, and improving user experience.
Alternatively, in some embodiments of the disclosure, a suction opening 5 may be provided on a wall of the vacuum chamber, and the vacuum pump set 3 may be in communication with the vacuum chamber via the suction opening 5. In an embodiment of the disclosure, the suction opening 5 may be provided on the side wall of the lower chamber 11, and the vacuum pump set 3 may be in communication with the lower chamber 11 via the suction opening 5, to draw the air inside the vacuum chamber. Apparently, the suction opening 5 may be provided on the side wall of the upper chamber 21, and meanwhile the vacuum pump set 3 may be in communication with the upper chamber 21. Such change in the position of the suction opening 5 has similar advantages.
Further, in some embodiments of the disclosure, a clamp 7 may be arranged on the top surface of the base 1, and the clamp 7 and the heater 41 may be disposed at a same side of the lower chamber 11. During suction, the clamp 7 disposed beside the heater 41 may tightly clamp the opening of the vacuum package, to avoid displacement of the vacuum package which may affect normal suction operation during suction and heat-sealing, and thus ensure stable suction process. In particular, the clamp 7 may rise to tightly clamp the opening of the vacuum package during internal vacuum suction, and may descend into the base 1 during external vacuum suction, so as to avoid abutting on the vacuum package to affect normal external suction operation.
Alternatively, in some embodiments of the disclosure, the base 1 and the top lid 2 are hinged at a position on a side of the base 1 distal to the heater 41. In such a case, the heater 41 and the clamp 7 are proximal to the operating personnel and are convenient to use.
Further, in an embodiment of the disclosure, the vacuum chamber of the package machine body is defined by the lower chamber 11 of the base 1 and the upper chamber 21 of the top lid 2. The wall of the lower chamber 11 and the wall of the upper chamber 21 may be formed of PP, PC, or nylon. The above materials are easy to get and are applicable for manufacturing special-shaped structures, which are not easy to form by alloy materials, by injection moulding as demanded. In practice, the operating personnel may select one or more of the materials depending on requirements for the vacuum package machine to withstand the pressure. It should be noted that, other portions of the base 1 and the top lid 2 which do not need to withstand the pressure may be formed of other type of plastic materials to lower the cost of the vacuum package machine.
Moreover, it should be noted that the top lid 2 of the vacuum package machine may also be formed of other materials, such as nylon, glass, which can be injection molded easily. In particular, the top lid 2 may be formed of transparent glass. In such a case, the top lid 2 may not be provided with the upper chamber 21, but the particular suction condition inside the lower chamber 11 can be clear from the transparent top lid 2.
To sum up, the disclosure provides a multifunction vacuum package machine, which comprises the base and the top lid hingedly connected with each other, wherein the top surface of the base defines a lower chamber, and the bottom surface of the top lid defines an upper chamber. The base is arranged with the heating system, the vacuum pump set, and the control system. The heating system includes the heater and the pressing strip. The heater is disposed on the base and is placed outside the lower chamber, and the pressing strip is disposed on the top lid and is placed outside the upper chamber. The vacuum pump set is in communication with the lower chamber via the suction opening provided on the wall of the lower chamber. The control system serves to control the heater and the vacuum pump set to perform heat-sealing and suction operations. Compared with the prior art, the multifunction vacuum package machine optimizes the position of the heating system, reduces the volume of the vacuum chamber, and lowers the requirement on the power of the vacuum pump set and thus the cost. The multifunction vacuum package machine can be applied on both internal vacuum suction and external vacuum suction, and has improved practicability. It is convenient to use and easy to popularize.
All the above are merely some preferred embodiments of the disclosure. It should be noted that the disclosure is intended to cover various modifications and equivalent arrangements included within the principle of the disclosure made by those skilled in the art.
