Gas stove with manual delay solenoid valve cooperated with piezoelectric ignition

Abstract

The invention relates to a hand-operated time-delay electromagnetic valve and piezoelectric ignition combined gas cooker, which is free from a power supply and can automatically prolong the ignition time by manually pressing and opening the gas gate of an electromagnetic valve; as no battery is used, the coil of the electromagnetic valve cannot be burnt out, and the failure rate is very low; an extinguishing protection function is achieved, that is, the gas gate can be closed automatically if fire is extinguished by wind or boiling and spilling water, so that no fuel gas escapes to cause safety accidents; a timing gas turn-off function is achieved, that is, the electromagnetic valve can automatically close the gas gate when the set gas turn-off time is up, so that a user doesn't need to be careful of remembering to turn off gas to prevent food from being burnt; the gas cooker is an environment-friendly gas cooker product which is simple in structure and low in cost, is generally suitable to being used as a cooker of liquefied gas, coal gas, natural gas, marsh gas or the like, and is a practical gas cooker product for families and the catering industry.

Description

Technical field: [0001] The manual time-delay solenoid valve is combined with the piezoelectric ignition gas stove, which belongs to the household gas stove product, and the gas stove combustion technology suitable for liquefied petroleum gas, coal gas, natural gas and biogas. Background technique: [0002] The manual time-delay solenoid valve combined with the piezoelectric ignition gas stove is evolved from wood burning stoves and coal burning stoves. It has developed rapidly in recent years and has become popular rapidly. The earliest gas stoves were ignited with an open flame, and later piezoelectric ceramic ignition technology was used on gas stoves, called piezoelectric ignition. With the development of electronic technology, high-frequency electronic pulse ignition came into being, referred to as electronic ignition. With the development of electronic ignition device, a device that prevents gas leakage caused by wind blowing out and waterproof extinguishing is produce...

Problems solved by technology

However, they are all common technologies that cooperate with electronic ignition devices. They need a power supply, and most of them are powered by batteries. However, battery power supply has disadvantages. The new battery has sufficient power, and the ignition time is long. It is easy to burn out the solenoid valve coil. It needs to be ignited multiple times or for a long time, and it is easier to burn the solenoid valve coil. According to some professional maintenance personnel: Electronic ignition loves to go wrong, and once it breaks, it has to be replaced. It is very troublesome. Simply replace it with a piezoelectric igniter

However, even if the electronic ignition device is improved, there is still the need to change the battery to affect the use, especially when the fire is extremely needed and cannot be ignited.
