Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] See also Figure 1-8 The utility model provides a portable mini sealing machine, including an outer shell 1, a sealing groove 5 is provided on the left end of the outer shell 1, a battery 2 and a circuit board 3 are fixedly installed inside the outer shell 1, the positive and negative poles of the battery 2 are electrically connected to the circuit board 3 through wires, and two electrical terminals 4 are fixedly welded on the circuit board 3. A spring 6 is fixedly installed on the left side of the inner shell 1, and an inverted T-shaped pressing block 7 is fixedly connected to the spring 6. The top end of the inverted T-shaped pressing block 7 passes through the outer shell 1 and is located in the sealing groove 5. A heating wire 8 is embedded on the top surface of the inverted T-shaped pressing block 7. Two electrode posts 9 connected to the heating wire 8 are fixedly mounted on the pressing block 7. The two electrode posts 9 are respectively located directly above the two electrical terminals 4 in a one-to-one correspondence. A push button 10 is slidably connected to the middle of the side of the outer shell 1. The push button 10 is fixedly connected to an insulating connecting frame 11 arranged inside the outer shell 1. An open slot 12 is provided on the left end of the insulating connecting frame 11. When the push button 10 is pushed to the left end, the inverted T-shaped lower pressing block 7 can pass through the open slot 12 and contact the electrical terminal 4. An upper pressing block 13 located directly above the inverted T-shaped lower pressing block 7 is fixedly mounted on the groove wall of the sealing groove 5.

[0024] The portable mini sealing machine uses a spring 6 to lift the inverted T-shaped pressing block 7, so that the electrode column 9 and the power terminal 4 are separated during use, so that the power is turned on and heated only after pressing down when sealing is required, which effectively extends the service life of the battery 2 and improves energy efficiency. By simply pushing the push button 10 left and right, it is possible to determine whether the electrode column 9 and the power terminal 4 will come into contact, thereby controlling the power on and off of the heating wire 8. The control is carried out by a physical isolation method, eliminating the electronic switch and wiring circuit of the traditional sealing machine, and eliminating the need for wiring or welding line operations, thereby improving production efficiency and saving manufacturing costs. In addition, the purely physical connection structure does not cause damage due to failures in the switch circuit, thereby improving circuit quality and extending service life.

[0025] The above-mentioned battery 2 is a rechargeable lithium battery, and a fast charging port 14 is fixedly installed on the outer shell 1. The battery 2 uses a rechargeable lithium battery and is equipped with a fast charging port 14, so that it can not only be used in an environment without power supply, but also can be charged quickly, meeting a variety of usage needs in different scenarios.

[0026] The above-mentioned outer shell 1 includes an upper shell 101, a lower shell 102 and a U-shaped plate 103. The upper shell 101 is fixedly mounted on the lower shell 102, and the U-shaped plate 103 is fixedly mounted at the notch formed by the left end of the upper shell 101 and the left end of the lower shell 102. The modular design makes the entire sealing machine compact, easy to assemble and maintain, and convenient for the layout and optimization of internal components, ensuring stability and durability in use; a push-down button 15 is fixedly mounted on the left end of the outer shell 1 just above the upper pressure block 13. Pressing the push-down button 15 is more convenient than pressing the entire upper part of the sealing groove 5, which enhances ease of use and makes the sealing operation more convenient; the corners on the outer shell 1 are rounded, and a plurality of decorative parts 16 are installed to decorate it into a submarine shape, so that while maintaining practicality, it also has aesthetics, which helps to attract people's attention and enhance the market competitiveness of the product.

[0027] When the portable mini sealing machine is in use, the push button 10 is pushed to the left, driving the insulating connecting frame 11 to move to the left, so that the opening groove 12 is located just below the inverted T-shaped lower pressing block 7. The plastic bag to be sealed is prepared, and the part to be sealed is placed flatly in the sealing groove 5 and located between the upper pressing block 13 and the inverted T-shaped lower pressing block 7. The push button 15 at the left end of the outer shell 1 is pressed downward to compress the spring 6. At the same time, the inverted T-shaped lower pressing block 7 moves downward and passes through the opening groove 12. The electrode column 9 on it contacts the power terminal 4 on the circuit board 3. After the electrode column 9 contacts the power terminal 4, the circuit board 3 will supply power to the heating wire 8, and the heating wire 8 will quickly heat up and soften the material to be sealed. The opening of the bag is kept pressed for a sufficient time to ensure that the plastic bag is fully heat-sealed; when the sealing is completed, release the push button 15, the spring 6 will return to its original state, push the inverted T-shaped push block 7 back to its original position, and the electrode column 9 is separated from the power terminal 4, thereby cutting off the power supply of the heating wire 8. If you need to continue sealing other plastic bags, just repeat the above steps; after use, push the push button 10 to the right, driving the insulating connecting frame 11 to move to the right, so that the leftmost end of the insulating connecting frame 11 is again located between the circuit board 3 and the inverted T-shaped push block 7, so that even if the push button 15 is pressed down, the electrode column 9 and the power terminal 4 will be isolated and will not contact each other.

[0028] 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
