As shown in fig. 1 to 7, a leakage-proof outdoor camping stove comprises a top stove head 1, an injection pipe 2 and a gas valve 3. The burner 1 is connected to the upper end of the injection pipe 2, the lower end of the injection pipe 2 is connected to the upper end of the gas valve 3, and the lower end of the gas valve 3 is connected to the gas outlet 61 of the gas tank 6.

Further, the gas valve 3 includes a valve body 30 and an ejector pin 31 provided in the valve body 30 and adapted to eject the gas outlet 61 of the gas tank 6. The diameter of the thimble 31 of the existing gas valve 3 is generally about 2mm and is a solid structure, and when the gas valve is used, gas leakage is easily caused at the joint of the gas valve 3 and the gas outlet 61 of the gas tank 6, or gas is not caused. The utility model discloses in, under above-mentioned gas valve 3 and the 6 equipment state of gas pitcher, the thimble 31 of gas valve 3 insert in the gas outlet 61 of gas pitcher 6 and with the sealing washer 611 circumference tight fit in the gas outlet 61. The diameter of the thimble 31 of the gas valve 3 is designed to be large enough, so that the thimble 31 is tightly matched with the sealing ring 611 in the gas outlet 61 in the circumferential direction, the sealing ring 611 has certain buffering and supporting effects on the weight of the outdoor camping stove, the weight of the outdoor camping stove can be prevented from being directly applied to the gas outlet 61 of the gas tank 6 to a certain extent even if the thimble is abutted against the top edge of the gas outlet, the gas outlet 61 of the gas tank 6 can be prevented from being collapsed, and meanwhile, the sealing performance of the joint of the gas valve 3 and the gas outlet 61 can be effectively ensured. In the present embodiment, the diameter of the thimble 31 of the gas valve 3 is preferably 3.1mm.

Further, in the assembled state of the gas valve 3 and the gas tank 6, a vertical gap (indicated by h in fig. 3) is provided between the upper portion of the thimble 31 of the gas valve 3 and the top edge of the gas outlet 61 of the gas tank 6 in the circumferential direction. This can fundamentally prevent the gas outlet 61 of the gas tank 6 from being collapsed by forming the upper and lower clearances. Preferably, in the assembled state of the gas valve 3 and the gas tank 6, the valve body 30 of the gas valve 3 is vertically abutted against the top edge of the mounting annular step 62 on the periphery of the gas outlet 61 of the gas tank 6. Thus assembled, the gas valve can be screwed to the bottom, and the weight of the outdoor camping stove can be applied to the mounting collar 62 of the gas tank 6, so that the above-described upper and lower clearances can be formed more stably, and the gas outlet 61 of the gas tank 6 can be prevented from being collapsed better.

Specifically, the valve body 30 is provided with a first boss 32 and a second boss 33 protruding from opposite sides thereof, wherein the first boss 32 has a first support plane 320 at the bottom thereof and the second boss 33 has a second support plane 330 at the bottom thereof. In the assembled state of the gas valve 3 and the gas tank 6, the first support plane 320 and the second support plane 330 respectively abut against the top edge of the mounting collar 62. Thereby enabling the weight of the entire outdoor camping stove to be more stably supported on the mounting collar 62 and thus enabling the outdoor camping stove to be more stably disposed on the gas tank 6. Preferably, in the present embodiment, the second boss 33 is fixed to the bottom of the knob structure 34 of the gas valve 3, so that the gas valve 3 can be simplified in structure and can be more stably supported on the upper mounting step 62.

Further, in order to facilitate the use of the pot, the circumferential side of the burner 1 is provided with a pot support 4, the pot support 4 includes three support legs 41, and at least has two states: in the unfolded state, the support legs 41 are circumferentially arranged around the burner 1 at intervals, so that the pot can be stably supported; in the storage state, the support legs 41 are circumferentially gathered and positioned on one side of the burner 1, so that the volume of the outdoor camping stove can be reduced, and the storage is facilitated. Furthermore, the lower ends of the supporting legs 41 of the pot support 4 are respectively and sequentially sleeved on the injection pipe 2 along the axial direction and can rotate circumferentially by taking the injection pipe 2 as a center. In the stored state, the lower ends of the legs 41 are sequentially aligned and stacked in the axial direction and the upper ends are sequentially aligned and stacked in the circumferential direction, and the stacking direction is identical to the knob structure 34. Thus, the pot support 4 can be folded by rotating the support legs 41, the outdoor camping stove can be stored, and convenience is brought to an operator.

In order to stably maintain the pot support 4 in the unfolded state during use, the outdoor camping stove of the present embodiment further comprises a positioning assembly for positioning the pot support 4 in the unfolded state. The positioning assembly includes a first positioning hole 411, a first positioning bump 413, a second positioning bump 414, and a second positioning hole 412, wherein the first positioning hole 411 is for the first positioning bump to be inserted into, and the second positioning hole 412 is for the second positioning bump to be inserted into. Specifically, the first positioning hole 411 is opened at the lower end of the leg 41 located at the upper side in the axial direction, the second positioning hole 412 is opened at the lower end of the leg 41 located at the lower side, and the first positioning projection 413 and the second positioning projection 414 are respectively projected on the upper surface and the lower surface of the lower end of the leg 41 located at the middle. Therefore, the pot support 4 can be stably kept in the unfolding state through the positioning assembly, and the phenomenon that the pot is unstably toppled due to the movement of each support leg 41 in the use process is avoided.

In addition, in order to avoid the pot support 4 from moving axially along the injection pipe 2, the upper end of the injection pipe 2 is also horizontally clamped with a limiting plate 7 along the circumferential direction, the limiting plate 7 is vertically abutted with the lower end of the support leg 41 of the pot support 4 positioned at the lower end, and the lower end of the support leg 41 of the pot support 4 positioned at the upper end is abutted with the bottom of the furnace end 1, so that the axial limitation of the pot support 4 can be realized.

In addition, the outdoor camping stove in this embodiment further includes a windproof ring 5, in a use state, the windproof ring 5 surrounds the periphery of the burner 1, and the lower end of the windproof ring 5 is detachably connected to each support leg 41 of the pot support 4. Thereby be convenient for the dismouting of windproof ring 5, and then convenience of customers' use. Specifically, the inner sides of the supporting legs 41 of the pan support 4 are respectively provided with a buckling projection 42 in a protruding manner along the radial direction, and the lower end of the windproof ring 5 is provided with a buckling groove 51 which is in one-to-one correspondence with the buckling projections 42 and into which the corresponding buckling projection 42 is buckled at intervals along the circumferential direction. Thus the utility model discloses a camping stove when outdoor use, prevent wind 5 effectual outdoor crosswind that blocks, guaranteed the normal of 1 flame of furnace end, and prevent wind 5 down ventilation on the circle and can provide sufficient combustion oxygen for furnace end 1, and have certain chimney effect, prevent wind 5 and make the abundant heat of flame burning not taken away by wind under the function that can provide to prevent wind to improve combustion efficiency.
