[0016] Below, the present application is further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0017] Please refer to Figure 1 , Figure 1 This is a circuit diagram of an embodiment of the stove circuit provided in the present application.

[0018] like Figure 1 As shown, the circuit of the stove includes a power supply component 110 , a protection circuit 120 , a control circuit 150 , and an ignition circuit 160 .

[0019] In one embodiment, the power supply assembly 110 is connected to the ignition circuit 160 and the protection circuit 120 , and the power supply assembly 110 provides power to the ignition circuit 160 and the control circuit 150 .

[0020] In one embodiment, the ignition circuit 160 is connected to the power supply assembly 110 and is configured to obtain electrical energy from the power supply assembly 110 and output an ignition voltage during ignition, so that the cooker has sufficient voltage for ignition.

[0021] In one embodiment, the control circuit 150 includes a control chip and / or a communication chip. The control circuit 150 receives the power supply voltage output by the power supply component 110 to ensure the normal operation of the control chip and / or the communication chip. The control chip can receive control instructions through the communication chip to control the operation of the stove, and can also send the usage status of the stove to corresponding devices, such as the user's mobile phone, through the communication chip.

[0022] In one embodiment, the protection circuit 120 is connected between the power supply assembly 110 and the control circuit 150 . When the ignition circuit 160 is turned on, the power supply assembly 110 also outputs a voltage interference, which is transmitted to the protection circuit 120 .

[0023] The protection circuit 120 eliminates voltage interference output by the power supply assembly 110 to prevent the voltage interference from being transmitted to the control circuit 150 during ignition.

[0024] In one embodiment, the power supply assembly 110 may include a battery mounting portion and wires. The battery mounting portion is used to mount a battery, and the power provided by the battery is used to ensure normal operation of the ignition circuit 160 and the control circuit 150 .

[0025] In one embodiment, the ignition circuit 160 includes an oscillator, a high-voltage rectifier circuit, and a booster connected in sequence. The oscillator includes a transistor, a resistor, and an inductor comprising three coils; the high-voltage rectifier circuit includes a half-wave rectifier diode; and the booster includes a primary coil and a secondary coil.

[0026] For example, when power supply assembly 110 is connected to ignition circuit 160, it provides power to ignition circuit 160, amplifies the voltage signal in the circuit via a transistor amplifier circuit, and converts the amplified voltage signal into alternating current via an inductor coil. This alternating current is then passed through a half-wave rectifier diode and stored in a capacitor. When the capacitor discharges, its two terminals are connected in parallel to the two terminals of the booster primary coil, and the boosted voltage is output through the secondary coil to power the pulse ignition pin located on the stove burner.

[0027] In one embodiment, if Figure 1 and Figure 2 As shown, Figure 2 The embodiment of the present application provides a schematic diagram of the voltage interference output by the power supply component during ignition. Figure 2 The voltage interference pulse shown is a voltage interference output by the power supply assembly 110 during ignition, which is transmitted to the protection circuit 120 . The protection circuit 120 eliminates the voltage interference and retains the supply voltage output by the power supply assembly 110 .

[0028] In one embodiment, the protection circuit 120 in the cooktop circuit includes a transient voltage sensor (TVS) and / or a varistor (ZR1). The TVS is connected in parallel with the power supply assembly 110, with one end connected to the positive electrode of the power supply assembly 110 and the other end connected to the negative electrode of the power supply assembly 110. The varistor (ZR1) is connected in parallel with the power supply assembly 110, with one end connected to the positive electrode of the power supply assembly 110 and the other end connected to the negative electrode of the power supply assembly 110.

[0029] For example, the voltage interference output by the power supply component 110 during ignition is transmitted to the protection circuit 120, and the surge voltage in the voltage interference is absorbed by the transient diode TVS. The transient diode TVS withstands the forward and reverse voltage shocks in a very short time, so that the voltage between the two levels is clamped at a preset specific voltage, thereby preventing the subsequent circuit from being subjected to voltage shocks.

[0030] For example, the voltage interference output by the power supply assembly 110 during ignition is transmitted to the protection circuit 120 , and the transient impact in the voltage interference is suppressed by the varistor ZR1 , thereby attenuating the voltage interference to protect the safety of subsequent circuits.

[0031] In one embodiment, the protection circuit 120 further includes a first inductor L1 and a second inductor L2, wherein the transient diode TVS and / or the varistor ZR1 are connected to the positive electrode of the power supply component 110 through the first inductor L1; the transient diode TVS and / or the varistor ZR1 are connected to the negative electrode of the power supply component 110 through the second inductor L2.

[0032] For example, the voltage interference output by the power supply assembly 110 during ignition is transmitted to the first inductor L1 connected to the positive electrode. The first inductor L1 attenuates the current of the interference to prevent the current interference from affecting the control circuit. The voltage interference output by the power supply assembly 110 during ignition is transmitted to the second inductor L2 connected to the negative electrode. The second inductor L2 attenuates the current of the interference.

[0033] In one embodiment, the protection circuit 120 further includes a first capacitor C1 , which is disposed close to the power supply component 110 and connected in parallel with the power supply component 110 . The first capacitor C1 is used for filtering and smoothing the supply voltage transmitted by the power supply component 110 .

[0034] Exemplarily, the power supply assembly 110 outputs a supply voltage and a voltage interference output during ignition. When the supply voltage and the voltage interference are input to the protection circuit 120 , the capacitor C1 in the protection circuit filters the supply voltage to smooth the supply voltage.

[0035] In one embodiment, the circuit of the cooker further includes a second capacitor C2, which is disposed near the control circuit 150 and is connected in parallel with the transient diode TVS and / or the varistor ZR1. The second capacitor C2 filters the supply voltage output by the power supply component 110 to smooth the supply voltage.

[0036] Exemplarily, the power supply component 110 outputs a supply voltage, which is filtered by the second capacitor C2 to smooth the supply voltage and output a first voltage.

[0037] In one embodiment, the circuit of the stove also includes a voltage stabilizing circuit 140, which is connected between the protection circuit 120 and the control circuit 150. The voltage stabilizing circuit 140 stabilizes the voltage output by the protection circuit 120 to prevent the power supply voltage output by the power supply component 110 from decreasing and adjusts the voltage, and transmits the stabilized voltage for use by the control circuit.

[0038] In one embodiment, the voltage stabilizing circuit 140 includes a voltage stabilizing chip U1 and its peripheral circuits. One end of the voltage stabilizing circuit 140 is connected to the protection circuit 120, and the other end is connected to the control circuit 150. The other peripheral circuits include a self-inductor L3 and a resistor R1 connected to the protection circuit, the other end of the resistor R1 is connected to a capacitor C3, and the other end of the capacitor C3 is grounded. The voltage stabilizing circuit 140 also includes a voltage stabilizing chip U1, which is respectively connected to the self-inductor L3, the resistor R1, the resistor R2, the ground, and the control circuit 150. The voltage stabilizing circuit 140 also includes a capacitor C4 and a capacitor C5. The capacitors C4 and C5 are connected in parallel and one end is connected between the control chip U1 and the control circuit 150, and the other end is grounded.

[0039] In another embodiment, a diode 130 is further provided between the voltage stabilizing circuit 140 and the protection circuit 120 . The anode of the diode 130 is connected to the protection circuit 120 , and the cathode of the diode 130 is connected to the voltage stabilizing circuit 140 .

[0040] Exemplarily, the first voltage output by the protection circuit 120 includes the supply voltage of the power supply component and the voltage interference generated during ignition. The protection circuit attenuates the voltage interference and outputs it to the diode 130. The diode 130 can limit the direction of the voltage and transmit the voltage to the voltage stabilizing circuit 140.

[0041] Exemplarily, the voltage stabilizing circuit 140 receives the voltage transmitted by the diode 130, stabilizes the voltage according to the voltage stabilizing chip U1, obtains a second voltage, and transmits the second voltage to the control circuit 150.

[0042] In one embodiment, the circuit of the stove further includes a control circuit 150, which is connected to the voltage stabilizing circuit 140. The control circuit 150 receives a second voltage transmitted by the voltage stabilizing circuit 140 and provides the second voltage to the control chip and / or communication chip as the required electrical energy.

[0043] The control chip is a control module that controls the cooker. The control chip is also connected to a communication chip that controls the cooker's communication functions. One end of the communication chip is connected to an antenna that transmits communication signals.

[0044] In one embodiment, when the communication chip receives the ignition instruction, it transmits the ignition instruction to the control chip. The control chip sends the ignition control instruction to the ignition circuit to control the ignition circuit to output the ignition voltage.

[0045] In another embodiment, the usage status of the cooker can also be sent to a corresponding device, such as a user's mobile phone, through a communication chip.

[0046] The user sends a control instruction to the communication chip through the device, and then the communication chip transmits the control instruction to the control chip to control the cooker.

[0050] The ignition circuit 221 of the circuit 220 of the stove is connected to the pulse ignition needle 211 .

[0051] The circuitry of the stove provided in the embodiments of this specification attenuates and eliminates voltage interference output by the ignition circuit through a protection circuit located between the stove's power supply assembly and the control circuit. A voltage stabilization circuit is also included between the protection circuit and the control circuit to stabilize the voltage output by the power supply assembly to provide power to the control circuit.
