Description

Technical Field

[0001] The utility model specifically relates to a modular electric flame cooker. Background Art

[0002] As a new type of technology, the electric flame stove still has many shortcomings and technical defects. For example, the patent with application number 201910967117X discloses an ionization combustion circuit and an electric flame stove. The ionization combustion circuit includes a power module, a voltage conversion module, a voltage doubler rectifier module, an ignition module and a combustion module; the power module is used to provide an input voltage; the voltage conversion module is connected to the power module to convert the input voltage into a driving voltage; the voltage doubler rectifier module is connected to the voltage conversion module to generate a rectified voltage according to the driving voltage; the ignition module is connected to the voltage doubler rectifier module to start an arc according to the rectified voltage; the combustion module is connected to the voltage conversion module to discharge to the ground according to the driving voltage. Since the voltage-doubling rectifier module increases the driving voltage by N times to generate a rectified voltage, the ignition module is used to start an arc and ignite according to the rectified voltage. When the ignition module breaks down the air, the combustion module discharges to the ground under the drive of the driving voltage to keep the heat source burning continuously. Therefore, only the ignition module needs to start an arc at high voltage, while the combustion module keeps burning under the drive of a lower driving voltage, which reduces the working power of the circuit, saves energy, and reduces the high-voltage resistance requirements of the device, thus reducing costs. However, in actual use of this prior art, since the combustion module works in a low-voltage environment, the combustion module is unstable and arc extinguishing often occurs, thus affecting the normal use of the electric flame stove. Utility Model Content

[0003] The utility model aims to overcome the above-mentioned shortcomings and provide a technical solution that can solve the above-mentioned problems.

[0004] A modular electric flame stove comprises: a power module, which, after receiving an AC mains voltage, converts the AC mains into a low-voltage DC voltage and outputs the voltage; a driving module, which is electrically connected to the power module and is used to convert the input DC power into a driving voltage; a boost module, which is electrically connected to the driving module and is used to adjust the driving voltage and generate a high-voltage voltage; a rectifier module, which is electrically connected to the boost module and is used to generate a doubled-voltage rectified voltage according to the high-voltage voltage; a burner head module, which is electrically connected to the rectifier module and is used to start an arc according to the rectified voltage and spray the high-energy plasma generated in the arc environment onto a pot body;

[0005] Preferably, a controllable switch for switching on or off the low-voltage DC voltage according to a control signal is provided between the power supply module and the driving module;

[0006] Preferably, it also includes a control knob connected to the driving module and used to generate a control signal according to user adjustment;

[0007] Preferably, the doubled rectified voltage is N times the high voltage, where N is an integer greater than 3;

[0009] Preferably, the rectifier module is further provided with a plurality of spring pins corresponding to the plasma torch, and the rectifier module outputs a doubled voltage rectified voltage to the plasma torch through the spring pins.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] 1. After the power module is connected to the AC mains voltage, it converts the AC mains into a low-voltage DC voltage, so that the power module, controllable switch, drive module, and control knob are in a low-voltage area, avoiding high-voltage voltage damage to the human body when the user touches the control knob or controllable switch;

[0012] 2. The boost module adjusts the driving voltage and generates a high voltage. The rectifier module generates a doubled rectified voltage according to the high voltage. The doubled rectified voltage is N times the high voltage, where N is an integer greater than 3. Compared with the prior art, the burner head module of the utility model obtains a higher voltage doubled rectified voltage, thereby ensuring that the electric flame stove can generate a stable arc during operation.
