Torch inner flame structure and torch containing it

Abstract

The invention discloses a torch inner flame structure and a torch containing it. The torch inner flame structure includes a gas channel, the outlet end of the gas channel forms an inner flame outlet, and the torch inner flame structure also includes a gas nozzle connected to a gas source. The nozzle of the gas nozzle is arranged towards the inlet end of the gas channel, a gap is formed between the gas nozzle and the inlet end of the gas channel, and the gas channel is connected to the outside through the gap, and the cross-sectional area of ​​the gas channel along the gas flow direction first becomes smaller and then becomes larger. The structure of the inner flame of the torch, by setting the cross-sectional size of the gas channel, uses the Venturi effect to eject the air near the nozzle, which greatly enhances the air ejection ability of the gas channel, so that the gas in the inner flame can burn more fully, without It will seize too much oxygen from the main flame, which is more conducive to the combustion of the main flame, making the main flame short and powerful, with a higher combustion temperature, which is more conducive to the improvement of the wind and rain resistance of the torch.

Description

technical field [0001] The invention relates to a torch inner flame structure and a torch containing the same. Background technique [0002] In the prior art, the handheld torch is a common equipment used in various sports games, event celebrations and other occasions, such as the Olympic Games, Asian Games, National Games, etc., and the torch relay is an important part of such activities that attract much attention. Extraordinary significance. When the torch is burning, it will encounter unexpected conditions such as strong winds and heavy rains, which will affect the burning of the torch. In order to protect the torch from being extinguished in case of an emergency, a variety of windproof, waterproof, and reflashing structures have been added in the prior art to reduce the probability of the torch being extinguished. [0003] Specifically, there is a burning inner flame inside the torch, and the function of the inner flame is to preserve the flame and re-ignite the main ...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to overcome the defects in the prior art that the inner flame consumes the main flame air due to insufficient air in the gas, which is not conducive to the combustion of the main flame, and provides a torch inner flame structure and its torch
