[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Implementation, for example Figure 1-2 As shown, this embodiment provides a handheld sealing machine, including a pair of handles 2 with connecting brackets 1 fixed to their ends. The two connecting brackets 1 are hinged together, and the ends of the two handles 2 are connected to each other by springs 3. Each connecting bracket 1 is connected to a sealing heating mechanism, which includes a long and narrow sealing heating strip 4. One side of the cross-section of the sealing heating strip 4 has a wave-shaped bite tooth structure 10. The two sealing heating strips 4 are parallel, of equal length, and opposite to each other. When the two handles 2 are pressed, the two sealing heating strips 4 can remain in close contact. In this embodiment, the sealing heating strip 4 of the cabinet-type sealing machine in the prior art is installed on the connecting bracket 1 with the handle 2. The handle 2 can be pinched with one hand to press and heat the upper and lower sealing heating strips 4 together. There is no need for a bulky cabinet as an additional component. The whole device can be freely and flexibly configured in various departments. In addition, the wave-shaped bite tooth 10 can realize multi-stage pressing and heat sealing, thereby making the heat sealing effect tighter.

[0018] The sealing heating mechanism also includes a housing 5 with heat dissipation holes 8. The housing 5, along with the sealing heating strip 4, is fixed to the connecting bracket 1, and the housing 5 and the sealing heating strip 4 are in close contact with each other. One side of the housing 5 houses a temperature control module, and the surface of this side of the housing 5 has a temperature adjustment button 6 and a temperature display screen 7. The other side of the housing 5 houses a battery. The temperature control module, sealing heating strip 4, battery, temperature adjustment button 6, and temperature display screen 7 are connected by wires. In this embodiment, the heat dissipation holes 8 on the housing 5 can improve the heat dissipation efficiency of the internal equipment and increase its service life. Moreover, the battery inside the housing 5 frees the equipment from the limitation of power cords, further increasing the flexibility of the overall equipment. Furthermore, this product has significant improvements over other sealing machines on the market in terms of temperature range and temperature sensing. While the highest temperature of other sealing machines on the market is 250 degrees Celsius, this product can reach 300 degrees Celsius, resulting in higher work efficiency. Regarding temperature sensing, other sealing machines on the market are significantly affected by mechanical reactions, requiring manual resetting when the temperature drops below the operating temperature. This product, through the innovative application of chip sensing, can automatically raise the temperature when it drops, with temperature fluctuations within 2 degrees Celsius. It can also sense when the temperature exceeds the set temperature and automatically cut off the power in time, reducing mechanical reactions and ensuring user safety. Timely power-off also reduces energy consumption and increases service life. The product mainly features digital display and temperature control functions. A temperature display screen 7 shows the operating temperature in real time, and the circuit board has a temperature control device. For example, if the temperature is set at 100 degrees Celsius, it will automatically cut off the power if it exceeds 1-2 degrees Celsius, and raise the temperature if it falls below 2 degrees Celsius. Unlike other machines on the market that rely on mechanical temperature responses, this product allows for temperature adjustment via the temperature adjustment buttons 6 on the digital display area.

[0019] One of the outer casings 5 ​​has a hook 9 fixed to it. In this embodiment, the hook 9 facilitates the storage of the device, making it flexible and quick.

[0020] In use, press the temperature adjustment button 6. The temperature adjustment button 6 adjusts the temperature of the sealing heating strip 4 through the temperature control module. The temperature control module also displays the temperature of the sealing heating strip 4 on the temperature display screen 7. When the sealing heating strip 4 is heated to a certain temperature, press the handle 2, causing the connecting bracket 1 to drive the wave-shaped teeth 10 on both sides of the sealing heating strip 4 to adhere to the packaging bag to be heat-sealed. After heat sealing is completed, release the handle 2. Under the action of the spring 3, the connecting bracket 1 rotates around the cross hinge point, causing the wave-shaped teeth 10 of the upper and lower sealing heating strips 4 to separate. The DS18B20 chip is used as the temperature control module.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
