[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a quick-disassembly air duct heater for an electric heating tube, including a heater, a disassembly mechanism is arranged on the outer surface of the heater, and an explosion-proof mechanism is arranged on one surface of the heater;

[0021] The disassembly mechanism 2 includes a fixing plate 201, a fixing table 202, a first limiting groove 203, a support column 204, a spring 205, a first latch 206, a second limiting groove 207, a first rotating shaft 208, a lock 209 and a third limiting groove 210. The outer surface of the heater 1 is fixedly connected with the fixing plate 201. The outer surface of the fixing plate 201 is fixedly connected with the fixing table 202. The outer surface of the fixing table 202 is provided with the first limiting groove 203. The inner surface of the first limiting groove 203 is fixedly connected with the support column 204. A spring 205 is sleeved on one side surface of the support column 204. The upper surface of the support column 204 is fixedly connected with the first latch 206. The second limiting groove 207 is provided on one side surface of the fixing table 202. The first rotating shaft 208 is installed on the inner surface of the second limiting groove 207. The outer surface of the first rotating shaft 208 is fixedly connected with the lock 209. The third limiting groove 210 is provided on one side surface of the lock 209. Through the settings of the fixing plate 201, the fixing table 202, the first limiting groove 203, the support column 204, the spring 205, the first latch 206, the second limiting groove 207, the first rotating shaft 208, the lock 209 and the third limiting groove 210, when the heater 1 needs to be disassembled, first, pull the lock 209 by hand, and the lock 209 will move downward. At this time, the first rotating shaft 208 in the third limiting groove 210 of the lock 209 will rotate in the second limiting groove 207 of the fixing table 202, and at the same time, pressure is applied to the first latch 206. The first latch 206 will push the support column 204 and the spring 205 in the first limiting groove 203 under the pressure of the lock 209. The spring 205 is under pressure and then rebounds. The rebounding force makes the fixing plate 201 drive the heater 1 to pop outwards, so as to play a role in disassembling the heater 1.

[0022] Further, the explosion-proof mechanism 3 includes a fixed column 301, a connecting ring 302, a protective sleeve 303, a connecting platform 304, a fixed block 305, a second rotating shaft 306, a second clamping block 307 and a support plate 308. One side surface of the heater 1 is fixedly connected with the fixed column 301. One end surface of the fixed column 301 is fixedly connected with the connecting ring 302. One end surface of the connecting ring 302 is fixedly connected with the protective sleeve 303. The inner side surface of the protective sleeve 303 is fixedly connected with the connecting platform 304. One side surface of the connecting platform 304 is fixedly connected with the fixed block 305. The outer side surface of the fixed block 305 is fixedly connected with the second rotating shaft 306. One side surface of the fixed block 305 is fixedly connected with the second clamping block 307. The outer side surface of the fixed block 305 is fixedly connected with the support plate 308. Through the settings of the fixed column 301, the connecting ring 302, the protective sleeve 303, the connecting platform 304, the fixed block 305, the second rotating shaft 306, the second clamping block 307 and the support plate 308, when the heater 1 needs to be used, first, when the temperature inside the heater 1 is too high, a large amount of high-temperature steam will be generated. At this time, the high-temperature steam will enter the protective sleeve 303 through the fixed column 301 and the connecting ring 302 at a very high speed and impact the fixed block 305 on the connecting platform 304. The second rotating shaft 306 on the impacted fixed block 305 will rotate rapidly, driving the second clamping block 307 to move downward. At this time, the support plate 308 under pressure will flip upward along with the second rotating shaft 306, effectively isolating the entry of high-temperature steam and preventing the heater 1 from exploding due to excessive temperature, thereby playing an explosion-proof role for the heater 1.

[0023] Further, there are four groups of fixing plates 201. The outer side surfaces of the fixing plates 201 are closely attached to the outer side surface of the fixed platform 202. Through the setting of the fixing plates 201, the fixing plates 201 are fixedly connected with the heater 1, so that the heater 1 can be fixed on the wall surface.

[0024] Further, there are two groups of springs 205. The outer wall size of the fixed platform 202 matches the inner wall size of the support column 204. Through the setting of the springs 205, the first clamping block 206 exerts a pressing force on the springs 205, so that the heater 1 can pop outwards.

[0025] Further, the inner wall size of the second limiting groove 207 matches the outer wall size of the first rotating shaft 208. There are two groups of support columns 204. Through the setting of the support columns 204, the support columns 204 are fixedly connected with the fixed platform 202 and the fixing plates 201, making the fixed platform 202 and the fixing plates 201 closely attached.

[0026] Furthermore, there are two sets of fixing columns 301. The inner wall size of the fixing block 305 matches the outer wall size of the second rotating shaft 306. Through the setting of the fixing columns 301, the fixing columns 301 are fixedly connected to the heater 1, making the fixing columns 301 and the heater 1 fit tightly.

[0027] Furthermore, one side surface of the connecting platform 304 is fixedly connected with a fixing column 301. There are two sets of connecting rings 302. Through the setting of the fixing column 301, the fixing column 301 is fixedly connected to the connecting platform 304, enabling the connecting platform 304 to be installed inside the protective sleeve 303.

[0028] Working principle: When the heater 1 needs to be disassembled, first, pull the latch 209 by hand, and the latch 209 will move downward. At this time, the first rotating shaft 208 in the third limiting groove 210 of the latch 209 will rotate in the second limiting groove 207 of the fixed platform 202. Meanwhile, apply pressure to the first latch 206. The first latch 206 will push the support column 204 and the spring 205 in the first limiting groove 203 under the pressure of the latch 209. The spring 205 is compressed and then rebounds. The rebounding force causes the fixing plate 201 to drive the heater 1 to pop outwards, thus playing a role in disassembling the heater 1. When the heater 1 needs to be used, first, when the temperature inside the heater 1 is too high, a large amount of high-temperature steam will be generated. At this time, the high-temperature steam will enter the protective sleeve 303 through the fixing column 301 and the connecting ring 302 at a very high speed, impacting the fixing block 305 on the connecting platform 304. The second rotating shaft 306 on the impacted fixing block 305 will rotate rapidly, driving the second latch 307 to move downward. At this time, the supporting plate 308 under pressure will flip upwards following the second rotating shaft 306, effectively blocking the entry of high-temperature steam and preventing the heater 1 from exploding due to excessive temperature, thereby playing an explosion-proof role for the heater 1.

[0029] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
