Description

Technical Field

[0001] The utility model relates to a circuit for delayed heat dissipation of a stove head fan, in particular to an electric flame stove. Background Art

[0002] The working principle of the electric flame stove is to generate electric flame by high voltage. Specifically, the transformer provides high voltage to the diode needle to generate plasma flame at the plasma head. The pot is placed on the pot ring, and the stove head fan makes the plasma flame spray out of the flamethrower to heat the bottom of the pot.

[0003] Since the working temperature of the burner is relatively high, the burner fan also plays a role in heat dissipation. In the prior art, when the electric flame stove is in low power output, the burner fan cannot obtain a suitable driving voltage and stops working, resulting in the "small flame" being unable to be ejected from the flame tube, affecting the performance of the electric flame stove, and the burner is very prone to aging and failure.

[0019] See also Figure 1In an embodiment of the utility model, a circuit for delayed heat dissipation of a stove fan 2 includes a linear regulator 100, a diode 200, a first capacitor 300 and a second capacitor 400;

[0020] The input end of the linear regulator 100 is connected to the first end of the second capacitor 400 and to the power supply V+, and the rated voltage of the power supply V+ is 12V; the output end of the linear regulator 100 is connected to the anode of the diode 200 and the first end of the first capacitor 300.

[0021] The cathode of the diode 200 is connected to the first end of the stove top fan 2 , and the first end of the stove top fan 2 is also connected to the control circuit 1 .

[0022] The second end of the first capacitor 300 is connected to the second end of the second capacitor 400 and is connected to the second end of the stove fan 2 and is also connected to the ground line. The first capacitor 300 and the second capacitor 400 are mainly used for circuit filtering.

[0023] The output voltage of the power supply V+ is 12V, and the voltage outputted by the output terminal of the linear regulator 100 is 5V.

[0024] Working principle of the circuit for delayed heat dissipation of stove fan 2:

[0025] When the user starts the electric flame stove through the control circuit 1, the control circuit 1 simultaneously provides a 12V driving voltage to the burner fan 2, so that the burner fan 2 rotates at a normal speed, providing sufficient air force for the plasma generated by the electrode assembly, thereby ensuring the combustion efficiency of the plasma; wherein the diode 200 prevents the 12V current from flowing back to the output end of the linear regulator 100, thereby protecting the linear regulator 100 from damage.

[0026] When the electric flame stove is in standby mode, the control circuit 1 stops providing 12V voltage to the burner fan 2 at the same time. At this time, the 5V voltage output by the linear regulator 100 continues to supply power to the burner fan 2, ensuring that the burner fan 2 obtains the minimum driving voltage and is sufficient to maintain the minimum speed, ensuring that the electrode assembly can continue to dissipate heat after the control circuit 1 is powered off, thereby extending the service life of the electrode assembly. At this time, the burner fan 2 operates at the lowest speed, reducing energy consumption.

[0027] The utility model also provides an electric flame stove, comprising any one of the above-mentioned circuits for delayed heat dissipation of a stove head fan 2 .
