Description

Technical Field

[0001] The utility model belongs to the technical field of gas valves, in particular to a pilot flame device. Background Art

[0002] A pilot flame is a small gas flame, usually fueled by natural gas or liquefied petroleum gas, used as a fire source to ignite higher-powered gas burners. Originally, pilot flames could only remain lit permanently, but this was a huge waste of gas. Nowadays, it is more common to ignite burners with electricity, but gas pilot flames are still used when a high-energy ignition source is required. Pilot flames are widely used in water heaters, central heating systems, fireplaces, flamethrowers and hot air balloons.

[0003] The pilot flame device in the prior art is generally arranged in the middle or side of the burner head, and a path of wind is drawn from the main fire air duct to the pilot flame assembly for air supply. When the main fire valve switches between large and small fires, the wind pressure changes accordingly, and the wind rush phenomenon is prone to occur, which eventually leads to the instability of the pilot flame device and accidental flameout. Therefore, how to ensure the stability of the pilot flame device is an urgent problem to be solved by technical personnel in this field. Utility Model Content

The pilot flame component 20 is connected to the separate blast component 40 through the connecting component 30. The blast component 40 provides wind for the pilot flame component 20 separately, thereby ensuring the combustion stability of the pilot flame component 20 and avoiding the accidental extinguishing of the pilot flame component 20 due to insufficient wind. At the same time, the connection between the pilot flame component 20 and the separate blast component 40 makes the pilot flame device form an independent component, which can be used with the burner at will, thereby increasing the adaptability of the pilot flame device.

[0034] The blower assembly 40 includes a blower 41 and a connector 42. The blower 41 is connected to the connector 42. The blower 41 is provided with a connecting port 43.
