DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0031] The following disclosure provides many different embodiments, or examples, for implementing different structures of the present application. For the purpose of simplifying the present application, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the present application. In addition, the present application can repeatedly refer to numerals and / or letters in different examples. Such repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0032] The electric heater generates heat through an electric heating element, and dissipates the heat to the surrounding environment through a heat sink or a fan.

[0033] In actual use, users sometimes accidentally cover clothes, towels or other sundries on the working electric heater, or place obstructions around the electric heater. This behavior can seriously hinder the normal heat dissipation process of the electric heater, causing the electric heater to continue to rise in temperature.

[0034] Currently, most electric heaters rely on users to manually cut off the power to avoid overheating risks, but users may not be able to cut off the power in time, and the temperature will rise to the flammable point of the clothes, causing a fire, seriously affecting the safety of users.

[0035] Therefore, in order to solve the technical problem that the existing dependence on manual power cut-off may not be able to cut off the power in time, causing a fire, seriously affecting the safety of users, the present application provides an electric heater, which can realize real-time understanding of the temperature change of the electric heater, and when the temperature is detected to exceed the preset threshold, it can take timely and automatic measures (such as reducing power or cutting off power), thereby improving the safety of the electric heater in use., see the following embodiments.

[0036] Referring to Figures 1-6 The electric heater 10 provided by the present application comprises a body 100, a heating element 200, a temperature detection device 300 and a controller.

[0037] Among them, the heating element 200 is arranged on the body 100; the temperature detection device 300 is arranged on the body 100, and the temperature detection device 300 is arranged above and close to the heating element 200; the temperature detection device 300 is configured to detect the temperature of the heating element 200; and the controller is configured to control the heating element 200 according to the detection result of the temperature detection device 300.

[0038] This embodiment introduces a temperature detection device 300 and a controller, which can realize real-time monitoring and intelligent control of the working state of the electric heater 10. When the temperature detection device 300 detects that the temperature exceeds the set safety threshold, the controller can automatically cut off the power or reduce the power output of the heating element 200, avoiding the temperature continues to rise, thereby improving the safety of the electric heater 10 in use, and improving the technical problem that the existing dependence on manual power cut-off may not be able to cut off the power in time, causing a fire, seriously affecting the safety of users.

[0039] In addition, since the heating body inside the body 100 is directly above the body 100, it is the most sensitive part of the temperature change reaction of the body 100, therefore, the temperature detection device 300 is arranged above and close to the heating element 200, which can quickly and accurately detect the temperature change, so that the controller can respond in time.

[0040] In some embodiments, the temperature detection device 300 comprises a temperature breaker 310 and a negative temperature coefficient thermistor 320, and the controller is configured to control the heating element 200 according to the detection results of the temperature breaker 310 and the detection results of the negative temperature coefficient thermistor 320.

[0041] The temperature detection device 300 comprises two modes of action: high-temperature automatic power-off and rapid temperature rise automatic power-off.

[0042] When the body 100 rapidly rises in temperature, the negative temperature coefficient thermistor 320 (NTC) acts to cut off the circuit. Specifically, for example, when the electric heater 10 is covered by clothes, the temperature of the electric heater 10 will rapidly rise, and in particular, the negative temperature coefficient thermistor 320 arranged on the top of the heating element of the electric heater 10 will first sense the temperature change of the body 100. When the temperature of the negative temperature coefficient thermistor 320 rapidly rises, the negative temperature coefficient thermistor 320 will act, causing the entire machine to trip, thereby completing the action of the rapid temperature rise automatic power-off of the electric heater 10.

[0043] When the temperature of the body 100 rises above a certain value, the temperature breaker 310 acts to cut off the circuit. Specifically, for example, when the electric heater 10 is blocked, the temperature of the electric heater 10 will gradually rise, and when the temperature rises to a certain value, in the case that the negative temperature coefficient thermistor 320 fails, the temperature breaker 310 inside the body 100 will act, causing the entire machine to trip, thereby completing the action of the high-temperature automatic power-off of the electric heater 10.

[0044] In this way, by introducing the dual protection mechanism of the temperature breaker 310 and the negative temperature coefficient thermistor 320, and combining intelligent control by the controller, comprehensive protection of the electric heater 10 is achieved, greatly improving the safety of the electric heater 10.

[0045] In some embodiments, the body 100 comprises a shell 110 and a handle 120 connected together, and the temperature detection device 300 is arranged on the handle 120.

[0046] In some embodiments, the handle 120 is detachably connected to the shell 110.

[0047] In this way, arranging the temperature detection device 300 on the handle 120 makes it more convenient to maintain and replace the temperature detection device 300, reducing maintenance time and cost.

[0048] In some embodiments, the body 100 further comprises a mounting bracket 130, and the temperature circuit breaker 310 and the negative temperature coefficient thermistor 320 are mounted on the handle 120 through the mounting bracket 130.

[0049] In this way, the temperature circuit breaker 310 and the negative temperature coefficient thermistor 320 are fixed on the handle 120 through the mounting bracket 130, which ensures that the temperature circuit breaker 310 and the negative temperature coefficient thermistor 320 can be firmly maintained in a predetermined position, improves the stability of the temperature detection device 300, prevents loosening or displacement caused by external factors, and thus ensures the stable operation of the electric heater 10.

[0050] In some embodiments, the mounting bracket 130 is detachably connected to the handle 120.

[0051] In some embodiments, the mounting bracket 130 is provided with a plurality of first connecting parts 131, and the handle 120 is provided with a plurality of second connecting parts 121, each of the first connecting parts 131 corresponds to one of the second connecting parts 121, and the first connecting part 131 can be fixedly matched with the corresponding second connecting part 121.

[0052] In some embodiments, the first connecting part 131 can be a mounting hole, and the second connecting part 121 can be a mounting column, which can be inserted into the mounting hole and then further fixed.

[0053] In some embodiments, the handle 120 is further provided with a plurality of reinforcing parts 1211, each of the reinforcing parts 1211 corresponds to one of the second connecting parts 121, and each of the reinforcing parts 1211 is connected to the corresponding second connecting part 121 and the handle 120.

[0054] In this way, by providing the reinforcing part 1211 at the second connecting part 121, the stability and structural strength of the second connecting part 121 can be improved, thereby improving the stability of the connection between the mounting bracket 130 and the handle 120.

[0055] In some embodiments, the handle 120 is provided with a containing groove 1212, and the containing groove 1212 is in communication with the outside of the body 100.

[0056] In some embodiments, the handle 120 is provided with an anti-skid part 1213, and the anti-skid part 1213 is arranged on the side wall of the containing groove 1212.

[0057] In this way, by providing the anti-skid part 1213 on the handle 120, the friction of the handle 120 can be increased, and the stability and comfort of holding can be improved.

[0058] In some embodiments, the anti-slip portion 1213 includes a plurality of anti-slip protrusions 1214 arranged in sequence along the circumference of the accommodating groove 1212.

[0059] The design of the anti-slip protrusions 1214 increases the friction of the surface of the handle 120, making the user more stable when holding the handle 120, reducing the risk of hand slipping.
