Ignition needle of gas stove and combustor provided with same

Abstract

The invention discloses an ignition needle of a gas stove. The ignition needle of the gas stove comprises a shell and an electrode needle arranged in the shell, wherein the top of the shell is closed;the ignition needle is characterized in that a through channel transversely penetrating through the shell is formed in the upper part of the shell, a first blocking part and a second blocking part are arranged on the two sides of the through channel along the penetrating direction correspondingly, an electrode needle head part extends into the through channel and is located between the first blocking part and the second blocking part, and a through hole with a net structure is formed in a first blocking piece; and the invention further discloses a combustor provided with the ignition needle.The ignition needle of the gas stove is provided with a transverse through channel at the upper part of the shell, the electrode needle head part extends into the through channel and is located between the first blocking part and the second blocking part, and the through hole with the net structure is formed in the first blocking piece, the speed of fuel gas flowing out of fire holes of a fire cover can be reduced, the interference can be reduced, and an ignition rate can be increased at the same time; and in addition, the first blocking part and the second blocking part are matched with a closed structure of the top of the shell, the electrode needle is surrounded, and accidental contact and scalding of a user can be prevented.

Description

technical field [0001] The invention relates to an ignition device, in particular to an ignition needle for a gas stove and a burner equipped with the ignition needle. Background technique [0002] The ignition forms of existing gas stoves can generally be divided into piezoelectric ignition and pulse ignition. The former converts kinetic energy into electrical energy, and each process produces a spark and a sound. Each ignition generally needs to be repeated many times to ignite, and the success rate of ignition is low. The latter converts the low voltage into a voltage of 8-16KV through a booster circuit, and generates 5-10 sparks per second, and it takes 0.2-0.3s to spread from a spark point to the surrounding combustible gas area. Continuous clicking sound, the success rate of ignition has improved, but there are still difficulties in ignition and failure to ignite. The success rate of pulse ignition is not only related to the discharge frequency, but also related to o...

AI Technical Summary

Problems solved by technology

It can only be ignited if the conditions are within a relatively suitable range. Although some gas sources have a very low ignition point, if they are not under suitable conditions, it is still difficult to ignite. There is often a sound of ignition but no fire. At the same time, it was lit again with a "bang", giving people a sense of fear without predicting

The traditional pulse circuit is relatively simple. After a misdischarge, there is no judging circuit, and high-voltage pulses will continue to be transmitted. If the person who is shocked has a pacemaker, it may cause harm.

In addition, the existing ignition pins are usually exposed, and are easily disturbed by the airflow during ignition. Not only the success rate of ignition is low, but also it is easy to generate noise. Inadvertent contact by the user will cause burns, which is not safe enough to use.
