Description

Technical Field

[0001] The invention relates to an outdoor appliance, in particular to an outdoor water boiling device. Background Art

[0002] When engaging in outdoor activities, whether it is camping, home travel, construction exploration, mountaineering and skiing, or outdoor sports, people's demand for water is the first priority. When people want to make tea, drink water or cook, they need to use boiled water. If it is simply used as drinking water, it can be obtained by bringing your own thermos cup or thermos pot, but making tea and cooking have certain requirements for the water temperature, and the temperature of the thermos cup and the amount of water it contains obviously cannot meet the needs.

[0003] The traditional kettle for boiling water is a flat-bottomed kettle. When boiling water, the bottom of the kettle is heated by flames. The water at the bottom of the kettle is heated and transfers heat to the upper water, gradually boiling the water. The disadvantage is that the kettle mainly absorbs heat from the flat bottom, and most of the heat is lost to the air. The heat exchange area at the bottom of the kettle is very limited, and the heat loss generated by the fuel is large. The thermal energy utilization rate is low, resulting in a long boiling time, slow temperature rise, and difficult to control the heating speed. Another disadvantage is that this flat-bottomed kettle requires a separate burning rack or a separate stove to be used with the fuel, which is large in size and not convenient for outdoor use. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies of the prior art and to provide an outdoor water heating device which has a simple structure, is easy to carry, can reduce heat loss and improve thermal energy utilization.
