Description

A portable heat sealing device

technical field

The utility model relates to a heat-sealing device, in particular to a heat-sealing device used as a thermoplastic material package for kitchen supplies, which is easy to carry and consumes less power.

Background technique

Traditional heat-sealing devices are generally divided into two categories: one is a fixed heat-sealing device, and the other is a portable heat-sealing device. Both heat sealing devices have advantages and disadvantages. The fixed heat sealing device is often used for the packaging of large objects, and the sealing performance is good and the power consumption is large. Portable heat-sealing devices are mostly used as kitchen supplies to seal small objects, and their power consumption is low. However, a heat-sealing device capable of encapsulating large objects with low power consumption has not yet appeared on the market. So the consumer either buys two heat sealers or accepts the defects of the heat sealer he buys.

The traditional portable heat-sealing device itself is small in size and has a heat-sealing area of about 1-2 cm, which is convenient for the user to hold and squeeze. However, it is more difficult to seal larger plastic bags with traditional portable heat-sealing devices. In order to seal smoothly and efficiently, the user must continuously press the heat-sealing device and drag the plastic bag continuously and smoothly along the heat-sealing area. If the improved heat-sealing device uses a longer heat-sealing area, a longer heating module will cause the heating module to stretch and work unsmoothly.

A traditional heat sealing device usually includes a body, a power supply, a rotating upper cover, a heating module and an overload protection device. When the upper cover is pressed toward the body, the heating module is energized to generate heat to seal the plastic bag. The overload protection device in the circuit will stop the heating module to prevent damage to the heat sealing device due to overheating. However, this overload protection device can only protect the heat-sealing device itself, but cannot protect the people who operate the heat-sealing device. For example, if a child plays with the heat-sealing device and does not notice or understand that the heating module of the heat-sealing device has been activated, the child is likely to be scalded.

Therefore, there is an urgent need for an improved portable heat-sealing device structure that can solve the above technical problems.
