[0021] 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.

[0022] Please see Figures 1-5 This utility model provides a technical solution:

[0023] A heating coil includes a heating coil body 1, a heat insulation mounting base 2 at one end of the heating coil body 1, a mounting groove 4 at the top end of the heat insulation mounting base 2, a pull rod 401 for hand gripping is installed inside the mounting groove 4, and a card seat 8 at the bottom end of the heat insulation mounting base 2 is provided, the card seat 8 is snapped into the inside of the outer casing.

[0024] The other end of the heating coil is provided with a heat insulation positioning seat 3. The bottom of the heat insulation positioning seat 3 is provided with a positioning groove 301. The inside of the positioning groove 301 is engaged with the positioning block provided at the bottom of the outer box.

[0025] This utility model uses components such as heating coil body 1, heat insulation mounting base 2, heat insulation positioning base 3, positioning groove 301, mounting groove 4 and pull rod 401 to facilitate the quick disassembly, inspection and replacement of heating coil body 1, thereby extending its service life and reducing losses.

[0026] Furthermore, when it is necessary to remove the heating coil from the heating equipment, the pull rod 401 provided in the mounting groove 4 can be held by hand to move the heating coil upward, so that the heat insulation positioning seat 3 on the other end of the heating coil can be removed from the positioning block inside the heating equipment, thereby making it easier to remove the heating coil from the inside of the external heating equipment for inspection and replacement.

[0027] The inner side of the heat insulation positioning seat 3 is provided with a high temperature resistant sleeve 302, which facilitates the sealing and fixing of the other end of the heating coil; the inside of the high temperature resistant sleeve 302 is engaged with the other end of the heating coil.

[0028] The heat-insulating mounting base 2 has a high-temperature resistant connection port 201 on its inner side, which makes it easy to insert the energized end of the heating coil into it so that the external heater can energize it and make it heat up; the interior of the high-temperature resistant connection port 201 is snapped into one end of the heating coil.

[0029] The bottom end of the heat insulation mounting base 2 has a symmetrical slot 6, and a locking block 7 is engaged inside the slot 6. The slot 6 and the locking block 7 are compatible with each other, and the bottom of the locking block 7 is fixedly connected to the mounting seat 8. By setting the above-mentioned slot 6, locking block 7 and mounting seat 8, the mounting seat 8 can be easily disassembled and installed.

[0030] The heat insulation mounting base 2 has a groove 5 on the upper front side, and the two ends of the groove 5 are equipped with heater connection ports 501 for connecting the heater to power.

[0031] By connecting the heater connection port 501 to an external heater, the external heater can be energized, thereby facilitating the heating coil to operate and thus enabling the heating of the liquid stored inside the external enclosure.

[0032] In practical use, when it is necessary to remove the heating coil from the heating equipment, the pull rod 401 set in the mounting groove 4 is held by hand to move the heating coil upward so that the heat insulation positioning seat 3 on the other end of the heating coil can be moved out of the positioning block inside the heating equipment, thereby making it easier to remove the heating coil from the inside of the external heating equipment for inspection and replacement.

[0033] 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.
