Description

Technical Field

[0001] The utility model belongs to the technical field of stoves, and particularly relates to a cyclone air inlet outdoor stove. Background Art

[0002] In recent years, outdoor sports have become a popular lifestyle, and more and more people have devoted themselves to outdoor adventures, fitness and leisure activities. Nowadays, outdoor stoves are subject to the conditions of use. The main air intake methods are divided into natural air intake and electric fan air intake. The corresponding outdoor products are also highly sought after. Outdoor stoves are one of the outdoor products.

[0003] Nowadays, outdoor stoves are subject to usage conditions, and their main air intake methods are natural air intake and electric fan air intake. Natural air intake has low air intake pressure and small air volume, so the combustion of the combustibles in the stove is often not complete, and there is a lot of smoke during combustion, and the environmental pollution is relatively serious; electric fan air intake solves the problems of low air intake pressure and small air volume. The combustibles in the stove burn more completely, there is almost no smoke, and there will be no major environmental pollution. However, it needs to be connected to a power supply when in use, which is complicated to use and difficult to maintain, and it is also easy to cause a waste of electricity. Utility Model Content

[0004] The utility model provides a cyclone air inlet outdoor stove, which can solve the problems pointed out in the background technology.

[0005] A cyclone air inlet outdoor furnace comprises a furnace body, which comprises a furnace shell and a furnace body. A plurality of spiral air duct partitions are arranged on the outer periphery of the furnace body. The spiral air duct partitions are arranged along the height direction of the furnace body. An ascending spiral air duct is formed between adjacent spiral air duct partitions. A plurality of air inlet holes are opened on the furnace body in the spiral air duct. An air inlet is arranged at the bottom of the furnace shell, and the air inlet is connected to the spiral air duct.

[0006] Preferably, a plurality of top air inlet holes are provided at the top of the furnace body.

[0007] Preferably, the air inlets are arranged in one-to-one correspondence with the spiral air ducts.

[0008] Beneficial effects: The utility model provides a cyclone air-inlet outdoor stove, which is innovatively designed for the existing outdoor stove air-inlet method, and uses the physical principle of the natural rise of hot air to heat-pressurize the natural air intake, and extends the heating distance through the design of the spiral air duct, thereby increasing the air intake flow rate and thus the air intake volume and wind speed. Compared with the two traditional outdoor stoves, it does not require the additional installation of an electric fan, is easy to use, simple to maintain, has a good combustion effect, and is fully and environmentally friendly.

[0013] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0014] Embodiment 1:

[0015] like Figure 1-2 As shown, a cyclone air inlet outdoor furnace includes a furnace body, which includes a furnace shell 1 and a furnace body 2. A plurality of spiral duct partitions 3 are provided on the outer periphery of the furnace body 2, and the spiral duct partitions 3 are arranged along the height direction of the furnace body 2. An ascending spiral duct 4 is formed between adjacent spiral duct partitions 3, that is, adjacent spiral duct partitions 3, the furnace shell 1 and the furnace body 2 form a spiral duct 4, and a plurality of air inlet holes 5 are opened on the furnace body 2 in the spiral duct 4. An air inlet 6 is provided at the bottom of the furnace shell 1, and the air inlet 6 is connected with the spiral duct 4. Specifically, the air inlet 6 and the spiral duct 4 are arranged in a one-to-one correspondence, and the air inlet 6 is arranged on the bottom plate 8 of the furnace shell 1. Under the action of the combustion heat in the furnace, the air in the spiral duct 4 is heated to form a spiral ascending airflow. The generation of airflow can effectively increase the air volume and air pressure of the incoming air. During this period, the incoming air continuously enters the furnace body 2 through the air inlet hole 5 to participate in the combustion, so that the combustion is more complete.

[0016] In some embodiments, a plurality of top air inlet holes 7 are provided at the top of the furnace body 2. The top air inlet holes 7 are opened on the upper part of the top furnace body head 9. The rising airflow in the spiral air duct 4 will converge at the top of the furnace body 2, and finally enter the interior of the furnace body 2 through the top air inlet holes 7, and participate in the combustion again, so that the incompletely burned materials can be completely burned, which is more conducive to complete combustion.

[0017] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
