[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0032] As Figure 1-7 shown, this embodiment discloses a glass-ceramic heating heater, which includes a housing 100. The housing 100 is composed of a plurality of profiles 102. An embedded groove 101 is provided in the housing 100, and the embedded groove 101 is closed; a glass-ceramic plate 200 is fitted in the embedded groove 101, and a nano-heating coating is evenly applied on the back surface of the glass-ceramic plate 200. In this way, the heat generated by the nano-heating coating can be evenly dispersed on the glass-ceramic plate 200, so that the glass-ceramic plate 200 generates heat evenly.

[0033] On one side of the housing 100, a control box 300 is provided. The control box 300 supplies power for the heating of the microcrystalline glass plate 200. A panel 301 is provided on the control box 300, and there are several buttons, indicator lights or display screens on the panel 301, providing instruction input or display for the heating of the microcrystalline glass plate 200. A circuit board 304 is provided inside the control box 300, and a control circuit is provided on the circuit board 304. The control circuit controls the power conduction of the microcrystalline glass heating appliance and the constant heating of the microcrystalline glass heating appliance.

[0034] As Figure 2 , Figure 3 , Figure 4 shown, the control box 300 and the housing 100 are fixedly connected by a plurality of connecting columns 302. One end of the connecting column 302 is fixedly connected to the bottom surface of the housing 100, and the other end is fixedly connected to the control box 300. Conductive columns 303 are also provided between the control box 300 and the housing 100. The conductive columns 303 are respectively disposed through between the control box 300 and the housing 100. A plurality of conductive pins are provided inside the conductive columns 303, and the conductive pins are respectively electrically connected to the microcrystalline glass plate 200 and the circuit board 304 to provide current conduction for the microcrystalline glass plate 200.

[0035] As Figure 5 , Figure 6 shown, the housing 100 in this embodiment is composed of a plurality of profiles 102, connecting pieces 103 and a bottom plate 104. The profiles 102 are connected to each other by the connecting pieces 103. The connecting pieces 103 are arranged in an arc as a transition connection section to form the frame of the housing 100. It should be noted that the housing 100 in this embodiment is a frame, but the housing 100 is not necessarily only a frame. It can also be set to other shapes such as a circle, and the corresponding shape can be formed by the profiles 102 and the connecting pieces 103.

[0036] Preferably, the nano-heating coating uses a graphene nano-heating coating.

[0037] Research shows that graphene has high electrothermal conversion efficiency. Due to the extremely high thermal conductivity coefficient and carrier mobility of graphene, electrical energy can be converted into heat energy in a very short time. Experimental data shows that the total effective electrothermal energy conversion rate of graphene heating materials can reach more than 99%.

[0038] The microcrystalline glass heating appliance has the characteristics of fast heating speed, high heating temperature, high electrothermal conversion efficiency, etc. The constant temperature function of the control circuit in this embodiment enables the control heating appliance to be in an intermittent working state, that is, heating for a period of time and then pausing for a period of time. The variable frequency constant temperature reduces energy consumption while meeting the heating requirements.

[0039] As Figure 7 , Figure 8As shown in the figure, the control circuit includes a power supply circuit, a timing circuit, a first monostable circuit, a second monostable circuit, an optocoupler controllable circuit, and an electronic switch. The power supply circuit is connected to the power cord to convert AC mains into DC power to supply power to the entire control circuit; the electronic switch is electrically connected to the conductive column 303 to control the power on and off of the conductive column 303, and control the heating of the glass-ceramics; the optocoupler controllable circuit is electrically connected to the electronic switch, and the optocoupler controllable circuit controls the start and stop of the electronic switch; the first monostable circuit and the second monostable circuit are electrically connected, and at the same time are electrically connected to the output signal of the optocoupler controllable circuit to activate the optocoupler controllable circuit; the timing circuit is electrically connected to the first monostable circuit, and the timing output signal stops the heater.

[0040] As Figure 9 shown, the power supply circuit includes capacitor C1, resistor R1, zener diode DW, rectifier diode Dl, capacitors C2, C3, and the power supply circuit converts AC mains into DC voltage; the timing circuit includes chip IC1, resistors R2, R3, capacitors C4, C5, C6, diodes D2, D3, transistor T1, potentiometer W1, and reset button K2; the first monostable circuit includes chip IC2, resistors R4, R5, R6, R8, capacitors C7, C8, C9, diode D4, transistors T2, T3, and potentiometer W2; the second monostable circuit includes chip IC3, resistors R9, R1O, R11, R12, R13, capacitors CIO, C11, diodes D5, D6, transistors T4, T5, T6, and potentiometer W3; the optocoupler controllable circuit includes optocoupler IC4, resistors R14, R15, light-emitting diode LED2; the electronic switch includes triac BTA and capacitor C12.

[0041] Chips IC1, IC2, and IC3 are all NE555 8-pin timer integrated circuits.

[0042] When starting up, close switch K1. The control circuit converts AC into DC through the power supply circuit. At the same time, the alternating current is connected to the glass-ceramics through the conductive column 303 to make the nano-heating coating heat up; the output of pin 3 of chip IC2 is high level to turn on the light-emitting diode LED2. LED2 is the heating indicator light. Optocoupler IC4 conducts, capacitor C12 charges, the base of triac BTA has an electrical signal, triac BTA conducts, and the live and neutral of the conductive column 303 form a loop, and the glass-ceramics heating heater starts to heat and warm.

[0043] Capacitor C7 stores energy. When the voltage rises to >2 / 3VDD, the output of pin 3 of IC2 is low level, optocoupler IC4 is cut off. After capacitor C12 discharges completely, triac BTA is cut off, the conductive column 303 is open-circuited and loses power, and the glass-ceramics heating heater pauses to heat up, and the indicator light LED2 goes out.

[0044] The capacitor C9 discharges rapidly through pin 7 of IC2 and D4 to prepare for the next charging; T3 is cut off, D6 is reverse-biased, and the DC power supply starts to charge C11 and T4 through W3 and R10. The voltages at pins 6 and 7 of IC3 keep rising. When it rises to 3VDD, pin 3 of IC3 outputs a low level, making T5 cut off and T6 conduct; the voltage previously charged in C7 discharges rapidly through T6, causing the voltage at pin 2 of IC2 to drop rapidly. When the voltage at pin 2 drops to <1 / 3VDD, IC2 is set, pin 2 of IC2 outputs a high level again, and the glass-ceramic heating warmer conducts and heats up again, repeating the above process.

[0045] As can be seen from the above, the first monostable circuit and the second monostable circuit form a multivibrator circuit; the first monostable circuit controls the heating-up time of the warmer. By adjusting the potentiometer W2, the heating-up time can be adjusted. The second monostable circuit controls the pause time of the warmer. By adjusting the potentiometer W3, the pause time can be adjusted.

[0046] When the timing time arrives, that is, when the voltages at pins 6 and 7 of ICl rise to >2 / 3Vnn, pin 3 of IC1 outputs a low level and D3 conducts forward, clamping the voltage at pin 4 of IC2 at about 0.2V. IC2 is forced to reset, pin 3 of IC2 outputs a low level, the optocoupler IC4 and the triac BTA are both cut off, the conducting column 303 loses power, and the AC power supply of the warmer is automatically cut off; at the same time, C6 discharges rapidly through pin 7 of IC1 and D2 to prepare for the next charging; by adjusting the potentiometer W1, the timing time can be adjusted. When the reset button K2 is pressed, pin 3 of IC1 outputs a high level again, and the oscillation circuit restarts oscillating.

[0047] The above is only the preferred embodiment of the present invention. Therefore, all equivalent changes or modifications made according to the structures, features, and principles described in the scope of the patent application of the present invention are included in the scope of the patent application of the present invention.
