A support column 21 is arranged in the middle of the cover body 20, the support column 21 is rotatably connected with the base body 10, and the support column 21 is hinged between the cutting end and the sealing end, so that the sealing device forms a seesaw structure, when the first end of the cover body 20 is pressed at the sealing end of the base body 10, the second end of the cover body 20 is tilted relative to the cutting end of the base body 10, and the second end of the cover body 20 is separated from the cutting end of the base body 10; when the second end of the cover 20 is pressed against the cutting end of the base 10, the first end of the cover 20 is tilted relative to the sealing end of the base 10, and the first end of the cover 20 is separated from the sealing end of the base 10.

As shown in fig. 1 to 4, the base body 10 includes a base 100 and an inner liner 200, the base 100 is provided with a connecting column 110, the inner liner 200 is provided with a connecting hole 210 corresponding to the connecting column 110, and the connecting column 110 is inserted into the connecting hole 210 in a tight fit manner. The coupling post 110 and the coupling hole 210 are engaged to fix the base 100 and the liner 200, and the coupling post 110 can support the liner 200 to support the liner 200 at the upper end of the base 100 without sinking. If the base 100 and the lining 200 are fixed only by the matching of the connecting column 110 and the connecting hole 210, the base 100 and the lining 200 are easily tilted, and particularly, the opening of the closed end of the seat body 10 is easily generated.

The heating assembly 300 includes a fixing frame 310, a heating wire, a ceramic head 320, a copper rivet, and a spring 330. The fixing frame 310 is provided with a guide groove, and the base 100 is provided with a guide post, which is embedded in the guide groove to enable the heating element 300 to move up and down along the guide post. The ceramic head 320 abuts against the heating wire, the upper end of the ceramic head 320 extends upwards out of the fixing frame 310, so that the heating wire also extends out of the fixing frame 310, and two ends of the ceramic head 320 abut against the lower part of the fixing frame 310. The upper end of the spring 330 abuts on the ceramic head 320, the lower end of the spring 330 abuts on the base 100, and the elastic force of the spring 330 causes the ceramic head 320 to tend to move upward. The copper rivet has two, and mutually independent setting is in ceramic head 320, and the both ends of heater and two copper rivet electrically connect respectively. The liner 200 is provided with a mounting opening through which the ceramic head 320 extends upwardly above the upper surface of the liner 200.
