Description

A self-powered gas stove electronic ignition device

technical field

The utility model relates to an electronic ignition device for a self-powered gas stove.

Background technique

Gas stoves can be seen in every household. People can use gas stoves for cooking, and gas water heaters (a modified gas stove) for showering and so on. Although the gas stove uses gas for combustion, the gas needs to be ignited by a gas igniter to start burning. However, gas electronic ignition devices all need external power sources such as batteries at present. From the user's point of view, the old battery cannot be replaced in time, which will cause the gas stove to fail, and the replacement of the battery also increases the cost and complexity of the gas stove. From the perspective of environmental protection, waste batteries will also pollute the environment.

Although, there are more new gas stove electronic ignition devices at present. For example, Patent No.: 200420011665, a new type of multi-ignition device for gas stoves, discloses a method of using multiple ignition needles to ignite simultaneously at different positions of the burner head, which effectively improves the ignition rate of the gas. But this device has increased the battery loss of gas cooker.

As another example, Patent No.: 200920181766 discloses an ignition device for a gas water heater. The power source of the device is a hydroelectric generator, which uses the power of water flow as the energy source for the ignition electrode. Although the device is also a self-powered ignition device, the device can only be limited to gas stoves such as water heaters that have water flow to pass through, and the ignition of gas stoves such as gas stoves cannot be realized by this device.

Therefore, realizing a self-powered electronic ignition device that can be used for any gas stove has very important practical value. Under the condition of not affecting the ignition effect, the device does not need an external power source such as a battery, and can realize self-power supply of the electronic ignition device of the gas stove.
