Technical Field

[0001] The utility model relates to a low-smoke stove, in particular to a rotary flame low-smoke stove. Background Art

[0002] In daily life or when people are camping outdoors, they often use stoves that burn firewood for cooking and other operations. This stove mainly uses the smokestack effect, that is, high temperature is generated by combustion, which increases the temperature of the gas inside the stove body and the upper part of the inner tank, and a pressure difference is generated inside and outside the stove body, causing the hot air inside the stove body to rise, and the external cold air is sucked into the stove body through the air inlet, so that a circulating airflow is formed inside and outside the stove body, thereby allowing the internal fuel to burn.

[0003] At present, the common stoves on the market are piled with combustibles on the fire tray during use. The combustibles will block the air inlet holes on the fire tray during use, and some larger combustion products will also block the air inlet holes on the fire tray, thereby affecting the air intake effect in the stove, causing the internal combustibles to burn incompletely, generating a large amount of smoke, and affecting the comfort of use.

The air provided three times and from different positions can enable the internal combustibles to be fully burned, thereby minimizing the amount of smoke generated by combustion and achieving a low-smoke and environmentally friendly effect; and because of the orientation of the inclined hole 6, the airflow entering the furnace body 1 from the inclined hole 6 will have a guiding effect on the flame, causing the flame above to produce a rotating effect, thereby forming a tornado flame effect, thereby enhancing the atmosphere of use.

[0026] When placing the furnace body 1, it is only necessary to flip the support legs 10 outward so that the support legs 10 are flipped outward from the bottom of the cross main frame 9 along the position connected to the cross main frame 9. The horizontal bar that the support legs 10 can be placed on can support the furnace body 1, and the vertical bar can be in contact with the ground to ensure stability.
