[0026] like Figure 1 to Figure 2 and Figures 10 to 12 As shown, the gas conveying member 4 includes a conveying pipe 41 and a protective cover 42. One end of the conveying pipe 41 is fixedly connected to the lower side of the gas carrier 3 and communicates with the cavity 31, and the other end is fixedly connected to the protective cover 42 and communicates with the inside of the protective cover 42. A starting ring 421 is fixedly connected to the bottom of the protective cover 42, and the other end of the conveying pipe 41 is located inside the starting ring 421. The protective cover 42 is put on the outside of the heating device 5, and the heating device 5 is turned on by the starting ring 421, so that the inside of the heating device 5 is communicated with the inside of the protective cover 42, so that the hot gas flows to the conveying pipe 41. The heating device 5 can be remotely controlled through a mobile terminal. The heating device 5 includes a heating shell 51 and a heating component 52. The heating shell 51 is fixedly connected to the lower side of the gun body 11. The heating shell 51 is located at the end of the gun body 11 away from the gas carrier 3; the heating component 52 is fixedly connected to the proximal end of the heating shell 51 close to the gun body 11; an extension ring 511 is fixedly connected to the distal end of the heating shell 51 close to the outer side, and a pair of protective plates 512 are rotatably connected to the extension ring 511. The protective plates 512 can be moved to the outside. The heating shell 51 rotates in the direction of the inner wall, the diameter of the pair of protective plates 512 matches the outer diameter of the starting ring 421, and when the protective cover 42 is completely sleeved on the outside of the heating shell 51, the starting ring 421 can push the pair of protective plates 512 to a vertical state with the extension ring 511; the inner wall of the heating shell 51 is fixedly connected with an elastic member 513; the elastic member 513 includes a spring 2 53 and a rotating plate 54, the lower end of the rotating plate 54 is rotatably connected to the inner wall of the heating shell 51, and one end of the spring 2 53 is fixedly connected near the upper end of the rotating plate 54, and the spring 2 53 The other end is fixedly connected to the inner wall of the heating shell 51; the upper end of the rotating plate 54 can be located within the diameter range surrounded by the pair of protective plates 512 in the natural state of the second spring 53; a traction rope 514 is fixedly connected between the pair of protective plates 512. After the protective cover 42 is pulled out, the second spring 53 can push the rotating plate 54 to rotate toward the protective plate 512, thereby pushing one of the protective plates 512 to rotate toward the far end of the heating shell 51. During the rotation of one of the protective plates 512, the traction rope 514 can drive the other protective plate 512 to rotate. The guard plate 512 rotates toward the distal end of the heating shell 51, thereby closing the port of the heating shell 51 to prevent external dust and other impurities from entering; the heating shell 51 is detachably fixedly connected to the protective cover 42, such as the outer wall of the heating shell 51 is provided with a thread, the thread is close to one end of the heating shell 51, and the corresponding inner wall of the protective cover 42 is provided with a thread. After the protective cover 42 is put on the outside of the heating shell 51, it is fixed by a threaded connection; the diameter of the protective cover 42 is greater than or equal to the outer wall diameter of the gun head 12, and the protective cover 42 can also be put on the outside of the gun head 12.

[0027] The heating assembly 52 includes a motor, multiple fan blades and a heating wire. The fan blades are fixedly connected to the outer wall of the motor's drive shaft. The motor is fixedly connected to one end of the heating shell 51. The heating wire is fixedly connected to the inner wall of the heating shell 51 and is located on the lower side of the fan blades. The fan blades are driven to rotate by the motor, and the generated air is heated when passing through the heating wire, and then flows toward the protective cover 42.

[0028] like Fig.13 As shown, a plurality of air inlet holes are provided on the surface of the extension ring 511, and the air inlet holes extend toward the delivery duct 41 to penetrate the protective cover 42, so that the interior of the heating shell 51 is connected with the exterior of the protective cover 42 through the air inlet holes to provide air volume for the fan.

[0029] Working principle: In the charging state, the protective cover 42 is put on the outside of the heating shell 51. When it is frozen, the user starts the heating component 52 through the mobile terminal to generate hot air. The hot air flows from the inside of the heating shell 51 to the delivery pipe 41, and flows to the cavity 31 inside the gas carrier 3 through the delivery pipe 41. The hot air is divided at the cavity 31. A part of the hot air flows to the heating air channel 22 through the cavity 31, and then flows to the heating hole 21 through the heating air channel 22, and finally flows out from the heating hole 21, thereby heating the outside of the gun head 21 and the gun head 21. The charging port in contact with the outside is heated and heated; another part of the hot air flows through the cavity 2 32, flows to the heating nozzle 33 and flows to the airway 1 34 through the cavity 2 31, and the gas at the heating nozzle 33 flows toward the sealing connection of the sealing member 23 to heat and heat the sealing connection and thaw the sealing connection; the hot air flowing to the airway 1 34 flows to the heating element 17 through the airway cavity 1211 and the airway 2 13, and flows out from the heating port 171 of the heating element 17 to heat, heat and thaw the limiting components 122 such as the spring 15; After heating for a certain period of time, press the control part 16. If the control part 16 cannot be pressed down due to freezing, continue heating. If it can be pressed down but still cannot be pulled out from the charging port, it means that the outside of the gun tip 2 and the charging port are still frozen. At this time, press the control part 16 downward until the card plate 161 contacts the positioning plate 172, and then move the control part 16 toward the heating part 17 to insert the card plate 161 into the heating port 171 to prevent hot air from flowing out of the heating port 171. At this time, the edge of the limiting shell 121 near the card slot 162 is located in the card slot 162, allowing more hot air to flow to the cavity 31, thereby increasing the heating and thawing effect on the sealed connection until the gun tip 2 can be pulled out from the charging port.

[0030] After charging is completed, unplug the gun head 2 from the charging port, unscrew the protective cover 42, then pull the protective cover 42 out of the outside of the heating shell 51 and put it on the gun head 2, and put it on the charging pile to prevent dust and the like from entering the inside of the gun head 2 or blocking the heating hole 21, and then turn off the heating component 52 through the mobile terminal; after the protective cover 42 is pulled out, the elastic force of the spring 2 53 pushes the rotating plate 54 to rotate toward the far end of the heating shell 51, and drives the other rotating plate 54 to rotate through the traction rope 514, thereby closing the port of the heating shell 51 to prevent dust and the like from entering.

[0031] When using it again, the protective cover 42 is pulled out from the gun head 2 and then put on the outside of the heating shell 51, and then fixed with threads. At this time, the starting ring 421 will abut against the protective plate 512 as the protective cover 42 gradually moves toward the gun body 11, and force the protective plate 512 to rotate toward the inner wall of the heating shell 51. At the same time, the protective plate 512 pushes the rotating plate 54 to move toward the inside of the heating shell 51 until the protective cover 42 is fixed to the heating shell 51. At this time, the traction rope 54 is straightened and the spring 2 53 is compressed, completing the connection between the gas conveying component 4 and the gas carrier 3 and the heating device 5; when it is pulled out after charging again, the specific operation method is the same as above, and the heating component 52 is started for heating and thawing.
