[0014] (1) This intelligent heater is equipped with a heating chamber, heat-conducting pipe, anti-slip plate, temperature indicator, heat-insulating plastic, knob, voice broadcaster, temperature sensor, mounting groove, handle groove, insulated handle, infrared heat radiation plate, heat dissipation hole, negative pressure fan, controller, temperature control circuit breaker, and voice module. The heater has a temperature sensor; when the temperature sensor detects that the temperature of the heat-conducting pipe reaches a specified threshold and the heat cannot be dissipated in time, causing overheating inside the casing, the temperature sensor sends a signal to the controller. The controller then activates the temperature control circuit breaker to immediately disconnect the heat-conducting pipe circuit through the circuit breaker system, and simultaneously sends a signal to the controller. When the negative pressure fan sends a signal, it starts and dissipates internal heat from the rear of the casing. At the same time, the voice module sends a signal to the voice broadcaster to announce the alarm and inform the user of the casing's operating status. The negative pressure fan stops when the temperature sensor detects that the internal temperature of the casing has returned to the normal threshold. The heat pipe then restarts at the temperature set by the knob, and the alarm ends. By adding a set of negative pressure fans between the heat pipe and the infrared heat radiation plate, in conjunction with the circuit breaker system, a fast and efficient over-temperature protection function can be achieved, avoiding damage to internal components caused by over-temperature and reducing safety risks.

[0015] (2) By setting a knob, heat-insulating plastic, handle groove and insulating handle, the housing uses a safe operating structure. When rotating the knob, the heat-insulating plastic around it provides a safe protection area to protect the hands from heat and prevent the knob from being burned by the high temperature due to the hot housing panel. The insulating handle at the back of the housing is stored in the handle groove. When using it, it can be flipped out. The bracket can also be folded up and stored for easy carrying. The housing is easy to move and use through the safe carrying design.

[0016] (3) By setting up a bracket, upper groove, lower groove, side groove, lever, rotating shaft, insertion hole, and spring, a set of foldable brackets is installed at the bottom rear end of the housing through the lower groove. When using the housing, the brackets are supported on the ground, and the housing is in a slightly backward and upright position. During operation, the lever is lifted up, the spring extends, and the bottom of the lever is pulled out from the insertion hole. At this time, the rotating shaft is released from restriction and can be flipped down. After flipping into place, the lever is released, and the bottom of the lever is reinserted into the insertion hole under the spring rebound to fix the rotating shaft. This prevents the housing and the bracket from rotating relative to each other when the bracket is supported on the ground, avoiding the common problem of unstable support caused by wear of bearing structures over the years.

Obviously, the described embodiments are only part of the embodiments of the utility model and not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the utility model.

[0024] Specifically, as Figure 1 And Figure 2As shown, the intelligent warmer is provided with a temperature sensor 9. When the temperature sensor 9 detects that the temperature of the heat pipe 3 reaches a predetermined threshold and the heat cannot be dissipated in time, causing the shell 1 to overheat, the temperature sensor 9 sends a signal to the controller 16, which controls the temperature control circuit breaker 17 to start the circuit breaker system to immediately disconnect the heat pipe 3 circuit, and sends a signal to the negative pressure fan 15, which starts to dissipate the internal heat from the rear of the shell 1, and the voice module 18 sends a signal to the voice broadcaster 8 to broadcast an alarm, prompting the user to check the operation status of the shell 1. When the temperature sensor 9 detects that the temperature in the shell 1 returns to the normal threshold, the negative pressure fan 15 stops, the heat pipe 3 is restarted to the temperature set by the knob 7, and the alarm is over.

[0025] A knob 7 is arranged at the middle position of the bottom of the front end of the shell 1, and a heat-insulating plastic 6 is arranged inwardly on the outside of the knob 7. A handle slot 11 is machined at the top of the rear of the shell 1, and an insulating handle 12 is installed in the handle slot 11.

[0026] Specifically, as shown in Figure 1 and Figure 2 , the shell 1 uses a safe operation structure. When the knob 7 is rotated, the heat-insulating plastic 6 around it provides a safe protection area to thermally protect the hands, avoiding high-temperature burns of the knob 7 due to the overheating of the shell 1 panel. The insulating handle 12 at the rear of the shell 1 is stored inside the handle slot 11. When in use, it is flipped out. The support 19 can also be folded upward for storage.

[0027] A lower slot 21 is formed on both sides of the bottom of the rear of the shell 1. An upper slot 20 is arranged above the left side of the lower slot 21. A side slot 22 is formed in the edge of the outer wall of the shell 1 and is connected to the upper slot 20. A spring 26 is fixedly connected to the inside bottom end of the upper slot 20. A push rod 23 is fixedly connected to the top end of the spring 26. The push rod 23 extends to the outside of the side slot 22. The push rod 23 is in the shape of a "T". A rotating shaft 24 is movably connected in the lower slot 21. The rotating shaft 24 is fixedly sleeved with a support 19 on the outside. There is a insertion hole 25 in the rotating shaft 24 for the bottom of the push rod 23 to be inserted. The support 19 is in the shape of a "U" and is supported on the ground.

[0028] Specifically, as shown in Figure 1 , Figure 2 , Figure 3 and Figure 4 , a set of foldable supports 19 are installed at the bottom of the rear of the shell 1 through the lower slot 21. When the shell 1 is used, the supports 19 are supported on the ground, and the shell 1 is in a slightly inclined upright state. When operating, the push rod 23 is lifted upward, the spring 26 is stretched, and the bottom of the push rod 23 is pulled out of the insertion hole 25. At this time, the rotating shaft 24 is released from the restriction, and it can be turned down to the outside. After turning to the right position, the push rod 23 is released, and the bottom of the push rod 23 is reinserted into the insertion hole 25 to fix the rotating shaft 24 under the action of the spring 26. When the support 19 is supported on the ground, the shell 1 and the support 19 cannot rotate relative to each other.

[0029] Working principle: at the bottom end of the rear of the shell 1, a set of foldable supports 19 are installed through the lower groove 21, when using the shell 1, the supports 19 are supported on the ground, the shell 1 is in a slightly backward inclined upright state, when operating, the lever 23 is lifted upward, the spring 26 is stretched, the bottom of the lever 23 is pulled out of the jack 25, at this time the shaft 24 is released, and the shaft 24 can be turned down, after turning to the position, the lever 23 is loosened, and the lever 23 is fixed in the jack 25 under the action of the spring 26, so that the shell 1 and the support 19 cannot rotate relative to each other when the support 19 is supported on the ground, the temperature is adjusted by rotating the knob 7, the current temperature is displayed by the temperature indicating table 5, and the heat is transmitted from the front of the shell 1 to the outside through the heat pipe 3. When the temperature sensor 9 detects that the temperature of the heat pipe 3 reaches a specified threshold value and the heat cannot be dissipated in time, causing the shell 1 to overheat, the temperature sensor 9 sends a signal to the controller 16, the controller 16 controls the temperature control circuit breaker 17 to start and immediately disconnect the heat pipe 3 circuit through the circuit breaking system, and sends a signal to the negative pressure fan 15, the negative pressure fan 15 is started, and the internal heat is discharged from the rear of the shell 1, at the same time, the voice module 18 sends a signal to the voice broadcaster 8, and the alarm is broadcasted to prompt the user the operation state of the shell 1. Until the temperature sensor 9 detects that the temperature in the shell 1 returns to the normal threshold value, the negative pressure fan 15 stops, the heat pipe 3 is started again to the temperature set by the knob 7, and the alarm is over. By increasing a set of negative pressure fans 15 between the heat pipe 3 and the infrared heat radiation plate 13, and cooperating with the circuit breaking system, the over-temperature protection function can be realized quickly and efficiently.
