[0002] The liquefied gas used in commercial stoves is naturally gasified by the liquid gas in the liquefied gas cylinder. Once the gas appliance is used continuously for a long time, the gasification amount of the liquefied gas in the cylinder cannot meet the normal use of the gas appliance, and the user has to replace the cylinder filled with liquefied gas. , resulting in a large amount of liquefied gas residual liquid remaining in the steel cylinders used, resulting in a waste of energy

At present, the liquid gas in the steel cylinder has been vaporized by heating with a gasifier. The electric heating equipment used for heating the gasifier consumes a lot of power and is gasified at high pressure, which has potential safety hazards.

CN 201344569Y discloses a preheating type liquefied gas energy-saving cooker. Its existing problems are: 1. High-pressure liquid gas directly enters the gasification ring pipe to absorb the heat of the furnace basin for gasification. Long-term heating will cause the gasification ring pipe to be gasified. Aging, short service life, prone to leakage points, large expansion coefficient of liquid gas, difficult to control the fire, and great potential safety hazards; 2. In order to solve the problem of preventing dry burning of the gasification ring pipe, it uses an electronic switch as a manual anti-dry burning When the preheating temperature exceeds the dangerous temperature, the power will be cut off for protection. This method is passive anti-dry burner. Once the manual anti-dry burner fails, it will lose the anti-dry burner function, which does not fundamentally solve the problem of potential safety hazards.

3. When the preheater is heating, when the gasification ring pipe reaches the specified temperature, the angle valve of the liquefied gas tank is manually opened, which is inconvenient to operate. In actual use, affected by human factors, it often opens before reaching the specified temperature. The angle valve causes the incompletely vaporized liquid gas to burn directly, resulting in the phenomenon of "fire-through" of the furnace basin
