Description

[0001]BARREL Technical FieldThe present invention relates to an outdoor windproof and frostproof candle burningbarrel. Background Art As people's living standards improve, outdoor activities are becoming more and more frequent, and various tools suitable for outdoor survival and exploration have become a necessity for people. Due to the complex outdoor environment and changeable climate, when unexpected situations occur, simple lighting is needed, but candles are difficult to ignite and continue to burn stably in outdoor environments, which brings inconvenience to people.Based on the above, the inventors found that traditional candles do not have the functionof wind and frost protection when burning outdoors. Even if they have the function, the structure is relatively complicated and the burning effect of the candle cannot be guaranteed. In view of this, the existing structure is studied and improved, and an outdoor windproof and frost-proof candle burning barrel is proposed to solve the above-mentioned problems.
