Description

Vacuum sealing device

The present invention relates to a vacuum sealing device, which can generate heat energy and seal a plastic bag after being evacuated.

The general vacuum air-sealing machine is used to pack and seal articles or food in a plastic or aluminum foil bag with high air-tightness, which can isolate gas, liquid, and even sunlight from entering and has a high degree of toughness. Under normal circumstances, it needs to be used together with a vacuum suction sealing machine. The main principle is to extract the gas in the packaging container and heat the contact part between the vacuum air sealing machine and the plastic bag, so that the contact part of the plastic bag and the vacuum air sealing machine is heated and melted and sealed, which can reduce the air in the bag Until the microorganisms cannot survive to prevent oxidation activities and food decay. Effectively keep the product fresh and highly extend the product life.

At present, the vacuum sealing machines on the market are mainly divided into box-type vacuum sealing machines and nozzle vacuum sealing machines. Box-type vacuum sealing machines are the most common vacuum sealing machines, also known as internal vacuum packaging machines. It is like a box, so its large size and heavy weight are the biggest disadvantages of this vacuum sealing machine, but the vacuum can reach the vacuum degree in the plastic bag. Compared with another type of vacuum sealing machine, it is the best at present. This box type The vacuum sealing machine puts the items that you want to vacuum into the plastic bag, and then puts it into the air tank in the vacuum sealing machine, before vacuum packaging, because the vacuum product needs to be put into the vacuum tank, the product will be exposed to vacuum. The size of the tank is limited. If the product is larger, the vacuum tank must be larger. The volume of the vacuum sealer The bigger the price, the higher the price. The box-type vacuum sealer is generally used for packaging of tea, dried fruit, rice grains, electronic parts, meat and powder.

The suction nozzle vacuum sealing machine belongs to the external pumping vacuum sealing machine. It is similar to the nozzleless vacuum sealing machine. The difference is that the suction nozzle vacuum sealing machine uses the suction nozzle to extend into the vacuum bag to extract the air, but the suction nozzle vacuum sealing machine Because of the suction nozzle, when the air is exhausted, the suction nozzle needs to be retracted into the machine to seal, so some air will enter when the suction nozzle moves. Therefore, the vacuum degree of the suction nozzle vacuum sealer is comparable to other vacuum seals. The machine is relatively low. In addition, when performing the sliding sealing of small bags, the bag body cannot be vacuumed at the same time and the bag body can be directly pulled and sealed, which is inconvenient to use. In addition, most suction nozzle vacuum sealing machines have a set Water cup, when the suction nozzle vacuum sealing machine vacuum-encapsulates the articles containing moisture or powder, it can make the inhaled trace moisture and powder flow into the water collection cup, so that the moisture and powder will not flow into the machine and cause mechanical failure .

However, the volume and weight of the above-mentioned vacuum sealing machine are quite large, and the power consumption is very high, it is inconvenient to carry, and the price is not very close to the people. In addition, the above three vacuum sealing machines have one thing in common is that they need to be plugged in. To use, if it is used in general households or when traveling, it is necessary to always look for plugs or sockets, which will be very inconvenient for users to use.

In view of this, the present inventors improved and solved the above-mentioned shortcomings, devoted themselves to research and cooperated with the application of scientific theory, and proposed an invention with reasonable design and effective improvement of the above-mentioned shortcomings.

The main purpose of the present invention is to provide a vacuum sealing device, which solves the problem that the bag body cannot be simultaneously evacuated and sealed by side pulling in the prior art.

Plays the role of elastic support and cushioning, and the elastic member 110 is, for example, a spring. Relative to the elastic element 110, the cover body 40 is provided with a tenon 406. When the cover body 40 is pressed down, the tenon 406 is clamped into the elastic element 110 so that the The cover 40 can be stabilized above the housing 10.

Next, please continue to refer to Figures 1 to 3, and to Figure 4A, which is a side view 1 of a preferred embodiment of the present invention, and Figure B, which is a preferred embodiment of the present invention The second embodiment of the side view, as shown in the figure, in this embodiment, the cover 40 includes a heat insulating member 404, which is disposed on the cover 40 relative to the heating wire 306, when the cover 40 When the other end is pressed down, the heat insulation member 404 contacts the heating wire 306. In this embodiment, the power supply device 50 is a rechargeable battery, and the casing 10 further includes an opening (not shown in the drawing), and the power supply device 50 is connected to the outside through the opening and charges the rechargeable battery.

In a preferred embodiment, the specific operation process is as follows. When the power supply device 50 is activated and power is transmitted to the vacuum pump 20 and the heating device 30, the vacuum pump 20 will continue through the tube 202 Inhalation, since the cavity 106 is provided on the housing 10, the inhalation range is enlarged, which is more conducive to the vacuuming of the bag opening. Secondly, the heating device 30 continuously emits heat energy, which is transferred to the heating wire 306 through the heat conducting member 304, and the sealing operation can be completed after the mouth of the bag passes through the heating wire 306. For example, when it is necessary to seal a plastic bag, adjust the switch 502 to the sealing position, first seal two thirds of the bag mouth with the heating wire 306, and then put one third of the remaining bag mouth into the cavity In the body 106, the switch 502 is adjusted to the vacuum position and the vacuum is performed. When the air in the pocket is almost in a vacuum state, the switch 502 is adjusted to the sealing position, and the pocket is directly pulled out. The last third of the sealing action can be completed. This design can complete the vacuum sealing of the larger bag. Compared with the conventional technology, the vacuuming device such as the tube body needs to be retracted before the sealing action is performed. In this case, after the vacuuming is completed, the sealing action can be performed by pulling sideways immediately, which is very convenient to use.

Wherein, during the vacuuming and sealing action, the cover 40 needs to be pressed. In order to better realize the sealing effect, the housing 10 is further provided with a first sealing member 108, which is arranged around the cavity. 106.
