Description

Technical Field

[0001] The utility model relates to the technical field of gas stoves, in particular to a valve body device for stoves and a gas stove. Background Art

[0002] With the continuous development of life, more and richer ingredients are entering people's tables. Different ingredients require different cooking methods, resulting in users' demands for gas stoves becoming more and more diverse. These demands are mainly for the needs of fire control in gas stoves. For example, some ingredients need to be stir-fried during the cooking process, and the thermal efficiency required for stir-frying is higher than that required for normal cooking. That is to say, the firepower of the gas stove needs to be suddenly transformed from normal cooking firepower to the firepower required for stir-frying, so as to meet users' needs for stir-frying ingredients.

[0003] The gas stove in the prior art adds a stir-fry pipeline on the basis of an ordinary gas pipeline, and a stir-fry solenoid valve is arranged on the stir-fry pipeline. The interior of the stir-fry solenoid valve is sealed by a conical air outlet and a conical plunger. This sealing form can easily cause the conical plunger to be inserted too tightly, which can easily cause the stir-fry solenoid valve to be unable to open or require a lot of force to open, resulting in poor reliability of the stir-fry function of the gas stove, which cannot meet the actual use requirements of the gas stove.

[0004] Therefore, there is an urgent need for a valve body device for a stove and a gas stove to solve the problems in the prior art. Utility Model Content

Under normal circumstances, the aperture of the inner ring nozzle 600 is small, the injection pressure is large, and the gas speed is fast, so that the flame is more concentrated and strong, which is suitable for rapid heating and cooking. The aperture of the outer ring nozzle 700 is relatively large, the injection pressure is small, the gas speed is slow, the flame is dispersed and relatively soft, and it is suitable for increasing the heating area with the inner ring firepower. By finely controlling the firepower, energy can be used more effectively and energy waste can be reduced, thereby achieving the purpose of energy saving and environmental protection.

The design of the inner ring shunt nozzle 800 and the outer ring shunt nozzle 900 can effectively reduce the gas flow rate and pressure, which helps to improve the safety of the gas stove. By throttling and reducing pressure, the amount of gas used can be reduced, thereby achieving the purpose of energy saving and environmental protection.
