[0022] The following further elaborates on the present utility model with reference to the embodiments given in the attached drawings.

[0023] As Figures 1 to 4 shown, this embodiment provides an outdoor stove, which includes a base frame 1 and a stove frame 2 arranged on the base frame 1, and a fuel tank 3 is arranged on the base frame 1. Specifically, a support leg 11 is further connected to the bottom of the base frame 1, and there are four support legs which are respectively arranged at the four corners of the bottom of the base frame 1. Such a structural design enables the outdoor stove to be supported more stably. An oil outlet 31 is arranged on the fuel tank 3, the oil outlet 31 is connected to an oil pipe joint 32, and the other end of the oil pipe joint 32 is connected to an oil drip bottle 33. An oil valve switch 34 is arranged on the oil pipe joint 32, which can be used to control the output of the fuel in the fuel tank 3. The other end of the oil drip bottle 33 is connected to an oil delivery pipe 4, and the oil delivery pipe 4 includes straight pipes 41 at both ends and an arc pipe 42 in the middle. The stove frame 5 includes a stove head 51 at the upper end and a cylinder body 52 at the lower end, and the cylinder body 52 includes an air inlet cylinder 53 at the outside and a combustion cylinder 54 arranged inside the air inlet cylinder 53. A combustion chamber 55 is arranged in the combustion cylinder 54, and the other end of the oil delivery pipe 4 is communicated with the combustion chamber 55.

[0024] As described above, a blower device 6 is further arranged on the base frame 1, the blower device 6 is communicated with the air inlet cylinder 53 and can blow air into the air inlet cylinder 53, and a plurality of air inlet holes 56 are arranged on the combustion cylinder 54 and are arranged around the outer periphery of the combustion cylinder 54 in a ring shape. Specifically, when the blower device 6 blows air into the air inlet cylinder 53, air can enter the combustion chamber 55 in the combustion cylinder 54 from the air inlet holes 56, enabling the fuel to have sufficient oxygen for combustion, thereby generating a larger flame and improving the heating efficiency.

[0025] As described above, the straight pipes 41 at both ends are located on the same horizontal line, and the arc opening of the arc pipe 42 faces upward. Such a structural design enables fuel to always remain in the arc pipe when the oil valve switch 34 is closed, which can prevent smoke from entering the oil drip bottle 33 from the straight pipe 41 and achieve a good oil seal effect.

Specifically, the arrangement of the ventilation hole 621 can conduct air transportation when the blower 61 is working.

[0029] As described above, a stove plate 521 is further provided on the cylinder body 52. The burner head 51 is detachably mounted on the stove plate 521. An opening 522 communicating with the inside of the combustion chamber 55 is provided at the center of the stove plate 521. The opening 522 extends upward along its edge to form a flame concentrating ring 523.

[0030] As described above, a fire extinguishing cover 7 is further included. The fire extinguishing cover 7 can be covered on the outer peripheral wall of the flame concentrating ring 523. After using the outdoor stove, the fire extinguishing cover 7 can be covered on the flame concentrating ring 523 to isolate the air in the combustion chamber 55 and achieve the effect of extinguishing the fire.
