[0022] In order to solve the technical problem of quickly cleaning the inner walls of the first insulation shell 1 and the second insulation shell 3 after use, as Figure 1-4 As shown, the following preferred technical solutions are provided:

[0024] The locking assembly 13 includes two locking shell groups 1301, and the rear sides of the two locking shell groups 1301 are movably connected to the first insulation shell 1 and the second insulation shell 3 respectively. The bottom of the front side of the inner cavity of the locking shell group 1301 is fixedly connected with a first positioning rod 1302, and the surface of the first positioning rod 1302 is clamped with the inner cavity of the positioning block 7, and the front side of the positioning block 7 is clamped with a second positioning rod 1303, and the front side of the second positioning rod 1303 extends to the outside of the positioning block 7 and is fixedly connected with the first locking shell 1304, and the rear sides of the two first locking shells 1304 are movably connected with the first insulation shell 1 and the second insulation shell 3.

[0025] Reinforcement rings 14 are fixedly connected to opposite sides of the two movable shells 5 , and one side of the reinforcement ring 14 close to the retaining ring 6 is fixedly connected to the retaining ring 6 .

[0026] A retaining rod group 15 is fixedly connected to the opposite side of the front side of the first heat-insulating shell 1 and the second heat-insulating shell 3 , and the surface of the retaining rod group 15 is engaged with the inner cavity of the locking shell group 1301 and the first locking shell 1304 .

[0027] The inner walls of the first heat-insulating shell 1 and the second heat-insulating shell 3 are made of stainless steel, and the reinforcing ring 14 is made of rock wool board.

[0028] Specifically, when the staff needs to quickly separate the first insulation shell 1 and the second insulation shell 3, the user drives the limiting shell 9 to move downward to disengage from the positioning plate 8. When the limiting shell 9 is separated from the positioning plate 8, the user drives the fixed shell 10 and the structure connected thereto to disengage from the positioning plate 8. When the limiting shell 9 and the fixed shell 10 are completely separated from the positioning plate 8, the user drives the locking shell group 1301 to move downward. The locking shell group 1301 drives the first positioning rod 1302 to disengage from the positioning block 7 while moving. When the rod 1302 disengages from the positioning block 7, the user drives the first locking shell 1304 and the second positioning rod 1303 to disengage from the positioning block 7. When the first positioning rod 1302 and the second positioning rod 1303 are completely disengaged from the positioning block 7, the user drives the retaining ring 6 and the positioning block 7 to move in a circle through the movable shell 5 and the retaining block group 4, and disengage from the inner cavity of the positioning plate 8. When the retaining ring 6 and the positioning block 7 are completely disengaged from the positioning plate 8, the user drives the first insulation shell 1 and the second insulation shell 3 to separate, thereby completing the rapid cleaning of the inside of the mica heater.

[0029] In order to solve the technical problem of stably fixing the positioning plate 8 by the connecting plate group 11 in the fixing shell 10, as shown in FIG. Figure 3 As shown, the following preferred technical solutions are provided:

[0030] Limit rods 16 are fixedly connected to both sides of the connection plate set 11 , and the surfaces of the limit rods 16 are fixedly connected to the positioning plates 8 .

[0031] Specifically, by providing the limiting rod 16 , the positioning plate 8 is secondarily fixed when the worker uses the fixing shell 10 to fix the positioning plate 8 , and at the same time, the positioning plate 8 and the fixing shell 10 are prevented from falling off during use.

[0032] In order to solve the technical problem of positioning the limiting shell 9 when the limiting shell 9 clamps the positioning plate 8, as shown in FIG. Figure 3 As shown, the following preferred technical solutions are provided:

[0033] The side of the locking rod 12 away from the connecting plate group 11 is fixedly connected to the limiting plate 17 , and the surface of the limiting plate 17 is locked with the inner cavity of the positioning plate 8 and the limiting shell 9 .

[0034] Specifically, by providing the limiting plate 17 , the limiting shell 9 is positioned when the limiting shell 9 clamps the positioning plate 8 , and the limiting shell 9 is prevented from falling off from the positioning plate 8 during use.

[0035] Working principle: When the staff needs to quickly separate the first insulation shell 1 and the second insulation shell 3, the user drives the limiting shell 9 to move downward to disengage from the positioning plate 8. When the limiting shell 9 is separated from the positioning plate 8, the user drives the fixed shell 10 and the structure connected thereto to disengage from the positioning plate 8. When the limiting shell 9 and the fixed shell 10 are completely separated from the positioning plate 8, the user drives the locking shell group 1301 to move downward. The locking shell group 1301 drives the first positioning rod 1302 to disengage from the positioning block 7 while moving. When the positioning rod 1302 disengages from the positioning block 7, the user drives the first locking shell 1304 and the second positioning rod 1303 to disengage from the positioning block 7. When the first positioning rod 1302 and the second positioning rod 1303 are completely disengaged from the positioning block 7, the user drives the retaining ring 6 and the positioning block 7 to move in a circle through the movable shell 5 and the retaining block group 4, and disengage from the inner cavity of the positioning plate 8. When the retaining ring 6 and the positioning block 7 are completely disengaged from the positioning plate 8, the user drives the first insulation shell 1 and the second insulation shell 3 to separate, thereby completing the rapid cleaning of the inside of the mica heater.

[0036] To sum up: the mica heater, through the coordinated use of the first insulation shell 1, the connecting shaft 2, the second insulation shell 3, the retaining block group 4, the movable shell 5, the retaining ring 6, the positioning block 7, the positioning plate 8, the limiting shell 9, the fixed shell 10, the connecting plate group 11, the locking rod 12, the locking assembly 13, the locking shell group 1301, the first positioning rod 1302, the second positioning rod 1303, the first locking shell 1304, the reinforcement ring 14, the retaining rod group 15, the limiting rod 16 and the limiting plate 17, solves the problem that the existing mica heater cannot be quickly cleaned after use.
