At present, the household gas cooker is used as an essential household appliance in a kitchen and exists in every household. The ignition mode of the gas stove generally adopts a pulse igniter for ignition, which needs an external battery for power supply. However, in the cooking utensils sold in the market at present, the external batteries are usually dry batteries, and need to be frequently replaced by users, which affects the use effect of the users.
Therefore, the technical problem to be solved by the utility model is to frequently replace the external battery in the prior art, so that the energy storage circuit of the cooker and the cooker are provided.

The thermocouple 1 is provided with a hot end and a cold end, and the hot end is suitable for being heated by flame generated by a stove burner 5; the energy storage battery 2 comprises an input end and a first power supply end, the input end is connected with the cold end, and the first power supply end is used for providing a first power supply V1 for the stove. The energy storage cell 2 also has a ground terminal, which is grounded. The external battery 4 is provided with a second power supply end which is used for providing a second power supply V2 for the cooking range; the power storage capacity of the energy storage battery 2 is greater than the power storage capacity of the external battery 4. The comparison circuit is provided with a first comparison end, a second comparison end and an output end, the first comparison end is connected with the first power supply end, the second comparison end is connected with the second power supply end, and the output end is connected with a load RL of the stove. When the voltage of the first power supply end is greater than that of the second power supply end, the first comparison end is communicated with the output end; when the voltage of the second power supply end is larger than that of the first power supply end, the second comparison end is communicated with the output end.

When the stove burner 5 burns, according to the first thermoelectric effect, two different electric conductors or semiconductors can cause an electric potential difference between the two substances due to the temperature difference. Therefore, the two ends of the cold-end metal of the thermocouple 1 generate potential difference, so that the heat energy dissipated in the combustion process of the cooker can be recovered by utilizing the first thermoelectric effect, and the energy storage battery 2 can be charged. Because the electric storage capacity of the energy storage battery 2 is greater than that of the external battery 4, when the electric storage capacity of the energy storage battery 2 is full, namely the voltage of the first power supply end is greater than that of the second power supply end, the first comparison end is communicated with the output end, and the second comparison end is disconnected with the output end, so that the energy storage battery 2 provides electric energy for a load RL in the stove, and the external battery 4 is disconnected with a passage of the load RL in the stove, so that the external battery 4 does not provide electric energy for the load RL, the electric consumption of the external battery 4 is saved, the service life of the external battery 4 is further prolonged, and the battery does not need to be frequently replaced.

When the stove burner 5 burns, according to the first thermoelectric effect, two different electric conductors or semiconductors can cause an electric potential difference between the two substances due to the temperature difference. Therefore, the two ends of the cold-end metal of the thermocouple 1 generate potential difference, so that the heat energy dissipated in the combustion process of the cooker can be recovered by utilizing the first thermoelectric effect, and the energy storage battery 2 can be charged. Because the electric storage capacity of the energy storage battery 2 is greater than that of the external battery 4, when the electric storage capacity of the energy storage battery 2 is full, namely the voltage of the first power supply end is greater than that of the second power supply end, the first comparison end is communicated with the output end, and the second comparison end is disconnected with the output end, so that the energy storage battery 2 provides electric energy for a load RL in the stove, and the external battery 4 is disconnected with a passage of the load RL in the stove, so that the external battery 4 does not provide electric energy for the load RL, the electric consumption of the external battery 4 is saved, the service life of the external battery 4 is further prolonged, and the battery does not need to be frequently replaced.
