Description

Technical Field

[0001] The utility model relates to the field of vacuum preservation, in particular to a vacuum machine with an automatic sealing structure. Background Art

[0002] A household vacuum sealer is a small household kitchen appliance that extracts the air from a vacuum packaging bag through a built-in small vacuum pump and an exhaust groove. After the vacuum is completed, the heat sealing component installed on the front side of the exhaust groove heat-melts the bag opening of the vacuum packaging bag and solidifies it to form a sealing strip that seals the bag opening.

[0003] However, the prior art has the following defects:

[0004] The sealing mechanism of the existing vacuum machine is narrow, resulting in poor sealing effect and inadequate sealing, which will cause air leakage in the packaging bag and a short vacuum state maintenance time, affecting the food preservation effect and time. The existing vacuum machine cannot cut the packaging bag, but the packaging bag is too large, which will not only affect the vacuum preservation effect but also prolong the vacuuming time and reduce efficiency. Utility Model Content

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a vacuum machine with an automatic sealing structure, comprising a vacuum machine body and a machine cover, one side of the top of the vacuum machine body is hinged to one side of the bottom of the machine cover, a third groove is opened in the middle of the top of the vacuum machine body, a vacuum groove is opened in the middle of the inner wall of the back side of the third groove, a limiting rod is fixedly installed on the inner wall of the bottom of the third groove, an inflatable pressure belt is fixedly installed on the outer wall of the bottom of the limiting rod, a heat sealing part is provided at the bottom of the inflatable pressure belt, an installation groove is opened on the side of the top of the vacuum machine body away from the machine cover, and a cutting mechanism is arranged inside the installation groove.

[0007] The above-mentioned technical scheme is adopted. The third groove of the scheme facilitates the insertion of the bag mouth of the packaging bag into the vacuum groove, which is convenient for the vacuum machine to vacuum the packaging bag. The limit rod is stuck at the bag mouth to prevent the bag mouth from warping and falling off, affecting the vacuum extraction work. The inflatable pressure belt is inflated and expanded to squeeze the heat sealing part to automatically seal the bag mouth.

[0014] The size of the cutting mechanism is smaller than that of the mounting groove, an L-shaped gap is left between the cutting mechanism and the mounting groove, and a plurality of convex strips are evenly distributed on both sides of the handle.

[0015] By adopting the above technical solution, the L-shaped gap of the solution facilitates the excess part of the packaging bag to pass through, and then the cutting mechanism is used for cutting, so that the packaging bag can be cut according to actual needs, reducing the vacuuming time and improving efficiency.

[0016] The four corners of the bottom of the vacuum machine body are fixedly installed with supporting feet, the middle of the two sides of the top of the vacuum machine body are embedded with second magnetic sheets, the middle of the two sides of the bottom of the machine cover are embedded with first magnetic sheets, and the first magnetic sheets are magnetically connected to the second magnetic sheets.

[0017] By adopting the above technical solution, the legs of the solution prop up the vacuum machine to prevent it from being close to the desktop, which can play a role in heat dissipation. The first magnetic sheet and the second magnetic sheet are magnetically attracted together to ensure the sealing performance of the vacuum machine body and the cover.

[0018] A first groove is provided in the middle of the front side of the machine cover, a second groove is provided in the middle of the bottom side of the machine cover, the corners of the first groove and the second groove are both rounded and chamfered, and a control panel is provided in the middle of the top side of the machine cover.

[0019] By adopting the above technical solution, the second groove of the solution is convenient for storing the raised part on the top of the vacuum machine body, so that the machine cover is tightly connected to the vacuum machine body, and the control panel is convenient for controlling and operating the vacuum machine.

[0020] Compared with the prior art, the beneficial effects of the utility model are:

[0021] The front end of the vacuum machine body of the utility model is provided with a cutting mechanism, which can cut the packaging bag according to actual use needs, can reduce the time for subsequent vacuum extraction, and improve the efficiency of the vacuum sealing machine. After the inflatable pressure belt is inflated and expanded, it squeezes the heat sealing piece to seal, and the heat sealing piece is wide, the heat sealing strength is large, and the sealing effect is good.
