Abstract

A kind of stove, including a stove head, a jet seat, a furnace tube and a scattering seat, in which the two ends of the furnace tube are assembled respectively. The furnace head is connected to the air injector seat and connected. The air inlet hole on the circumferential side of the furnace tube is located between the furnace head and the air injector seat. The heat dissipation seat surrounds the circumferential side of the furnace tube, and the transparent window of the heat dissipation seat is connected with the air inlet hole. The support legs that are rotated and connected to the heat sink are not in direct contact with the furnace tube. In actual use, under the action of the jet seat injecting fuel toward the burner head and the upward airflow generated by fuel combustion, the cold air from the outside can be sucked into the furnace tube through the windows and pores, thereby improving the combustion efficiency of air and fuel. The aforementioned cold air When inhaled, it can dissipate the heat from the heat sink and the furnace tube, and also reduce the heat transferred to the jet seat, effectively controlling the stove at a reasonable and normal operating temperature.

Description

stove

The invention relates to a stove, in particular to a portable stove.

Engaging in outdoor activities can not only exercise physical fitness, relieve stress in life, but also effectively regulate physical, mental and spiritual health. Today's busy people with busy working lives love to engage in outdoor activities such as mountain climbing, hiking, visiting natural attractions, camping, camping, river tracing, diving, SUP (Stand Up Paddle), etc. However, engaging in the above-mentioned activities will consume a lot of calories. It is necessary to take in food in a timely manner to obtain energy calories and replenish water to maintain the energy required for activities and avoid the danger of excessive physical exertion. However, eating outdoors is not as convenient as purchasing food anywhere in the city. Convenience, in addition to eating dry food quickly and conveniently, using portable stoves to cook food is a common choice.

Especially for long-term or overnight mountain climbing and camping activities, you have to carry the necessary items on your own. Therefore, the weight and volume of the items you carry will have its own considerations. Therefore, you usually choose a top stove or a spider as a cooking stove. Stove, this type is small and light and does not occupy the internal space of the backpack in terms of storage volume.

When a stove is used to burn fuel for cooking or boiling water, the heat of combustion will be transferred to the stove through thermal conduction and heat radiation, causing the relevant anti-leakage gaskets in the stove to be easily damaged, making it easier to use the stove in the future. A fuel leakage problem occurs.

The invention provides a stove, which includes a burner head, a jet seat, and a furnace tube, which is provided with a channel that axially penetrates the furnace tube, and the two ends of the furnace tube are used to assemble the burner head and the jet seat respectively, and with The channel connects the burner head and the jet seat; the furnace tube is provided with an air inlet connected to the channel and is located between the burner head and the jet seat; and a heat dissipation seat surrounds the furnace tube circumference, The heat dissipation seat is provided with a transparent window and is connected with the air inlet; in addition, the heat dissipation seat is provided with supporting legs that are rotationally connected and are not in direct contact with the furnace tube.

When the stove of this invention is actually used, the fuel is injected from the jet seat towards the burner head and the upward airflow generated by the fuel combustion causes the cold air from the outside to be sucked into the stove tube through the window and the air hole, which not only improves the combustion of air and fuel In addition to efficiency, the aforementioned cold air suction can dissipate the heat (thermal radiation and conduction) of the heat sink and the furnace tube, and can also reduce the heat transferred to the air jet seat, so that the stove can be effectively controlled to operate reasonably and normally. temperature, thus ensuring a leak-proof gasket in the stove.

In particular, the aforementioned transparent window 401 is not in direct contact with the hole edge of the air inlet hole 302 and the surface of the furnace tube 300, and there is a gap in the radial direction between them.

The heat dissipation seat 400 includes a ring portion 410 and an extension portion 420 surrounding the outer circumference of the ring portion 410, and the extension portion 420 has one end connected to the outer circumference of the ring portion 410 and the other end extending outward; the ring The portion 410 has an axially penetrating through hole 411 and is penetrated by the furnace tube 300. The aforementioned transparent window 401 communicates with the through hole 411; the support leg 500 is rotationally connected to the extension portion 420. The aforementioned extending portions 420 surround the outer circumferential side of the ring portion 410 at approximately equal intervals, and there are three extending portions 420 here, for example, and they are arranged in a radial pattern.

The heat dissipation base 400 is made of aluminum alloy; the outer peripheral side of the ring portion 410 is provided with an outwardly protruding heat conductive strip 412 and spans the transparent window 401; the peripheral side of the extension portion 420 is provided with a discontinuous flat surface 421. The aluminum alloy heat sink 400 has the advantages of good thermal conductivity and lightweight, and is suitable as a portable Stove 1 heat dissipation material. By disposing the heat-conducting strips 412 across the transparent window 401 , the heat-conducting strips 412 can dissipate heat before the cold air is sucked into the furnace tube 300 . The aforementioned discontinuous flat surface 421 of the extension portion 420 can increase more surfaces of the extension portion 420 to facilitate heat dissipation.

Please refer to Figures 1, 5 to 7, the upper end of the extension part 420 is provided with a sectional groove 422, the lower end of the extension part 420 is provided with a pivot hole 425 and is connected with the sectional groove 422, and the sectional groove 422 is provided with There is an expansion notch 423 extending toward the outside, and a collapsing notch 424 toward the adjacent extending portion 420; the support leg 500 is rotationally coupled to the pivot hole 425 with an insertion section 501. When the support foot 500 is manually operated so that the limiting section 502 of the support foot 500 is limited to the expansion notch 423, the support foot 500 is in an expanded state, and the remaining portion of the support foot 500 is generally directed outward from the extension portion 420. direction. When the support leg 500 is manually operated so that the limiting section 502 of the support leg 500 is detached from the unfolding notch 423 and moves to the collapsing notch 424 and is restricted by the collapsing notch 424 , the support leg 500 is in a folded state. , and the support foot 500 faces the adjacent extension part 420 and is stuck on the end surface 426 of the extension part 420 . Through the aforementioned operation of the support legs 500, the support legs 500 of the stove 1 can be quickly deployed and used stably, and the folded support legs 500 are stuck against the end surface 426 of the adjacent extension part 420, so that the support legs 500 will not extend relative to each other.
