Reference numeral 26 is a leaf spring fixing portion that fixes the end portion of the leaf spring 25, and 27 is a leaf spring supporting portion that is provided near the leaf spring fixing portion 26 and that supports the leaf spring 25 from below. Then, when the inside of the cartridge tank 7 is empty, the direction of the cut portion of the fulcrum portion 21 is aligned with the longitudinal direction of the keyhole-shaped hole 24 by the upward biasing force of the leaf spring 25 and even when the liquid fuel is contained. If not, the directions of the two do not match, so the main body case 7a, that is, the fulcrum portion 21
Does not descend, and the fulcrum part 21 only rotates in the upper circular part 24a. On the other hand, when the cartridge tank 7 is filled with the liquid fuel and becomes heavy, and the cut portion of the fulcrum portion 21 coincides with the longitudinal direction of the keyhole-shaped hole 24, the fulcrum portion 21 moves upward in the leaf spring 25. Against the spring force to the above, the lower rectangular portion 24b of the keyhole-shaped hole 24 is fitted and locked.

Next, the operation of the present embodiment constructed as above will be described. When the liquid fuel in the cartridge tank 7 is exhausted and refueling is performed, first, the grip portion 23 of the rotary handle 22 and the handle 14 shown in FIG. 1 are simultaneously gripped, and the cartridge tank 7 is pulled upward. At this time, the position of the center of gravity G is above the position of the line connecting the fulcrums 21 and 21 of the rotary handle 22, that is, on the handle 14 side.
When the handle 14 is released, the main body case 7a rotates about the fulcrums 21 and 21. In this way, the handle 14 side is facing down and the base 1
3 is up and stops at the position shown in FIG. On this occasion,
The fulcrums 21 and 21 rotate with the rotation of the main body case 7a, and since the liquid fuel is not contained in the cartridge tank 7, the fulcrum 21 is a keyhole-shaped hole 2 shown in FIG.
4 is rotated only in the upper circular portion 24a. In this state,
The cartridge tank 7 is placed on the floor or the like, and the position of the grip 23 is shifted to refuel.

When refueling is completed, the grip portion 23 of the rotary handle 22 is grasped and lifted, and the base 13 is rotated so as to be located below. Thus, when the mouthpiece 13 comes directly below as shown in FIG. 1, the inside of the main body case 7a becomes heavy due to the liquid fuel, and both cut portions of the fulcrum portion 21 shown in FIG. Since the fulcrum portion 21 opposes the force of the leaf spring 25 and moves from the upper circular portion 24a to the lower rectangular portion 24b as shown in FIGS. 3 to 4, the main body case 7a is fixed. . Even if liquid fuel is contained in the cartridge tank 7, if both cut portions of the fulcrum portion 21 are not parallel to the longitudinal direction of the keyhole-shaped hole 24, the fulcrum portion 21 moves in the lower rectangular portion 24b direction. It does not move, but freely rotates within the upper circular portion 24a.

Thus, the cartridge tank 7 is housed in the heater body with the mouthpiece 13 held downward and with one hand. Therefore, according to the second embodiment, the cartridge tank does not fluctuate, and the storage operation is easy. Since the weight of the cartridge tank 7 becomes lighter when the oil is exhausted, the fulcrum portion 21 integrated with the main body case 7a is urged upward from the lower rectangular portion 24b by the leaf spring 25, and the upper circular portion 24a. Move to.

Embodiment 3 FIG. 5 is a front view showing a third embodiment of the present invention, and FIG.

Although it is on the handle side with respect to the positions 1 and 21, in the present embodiment,
The position of the center of gravity G is made different when the liquid fuel is empty or full. 7a is a cartridge tank 7
The main body case 28 is a recess provided on the surface of the main body case 7a opposite to the base 13. In the cartridge tank 7, when the inside of the main body case 7a is empty (FIG. 5), the position of the center of gravity G is located closer to the recess 28 than the line connecting the fulcrums 21 and 21, and the liquid fuel is full. In the case of the amount (FIG. 6), the position of the center of gravity G is located closer to the mouthpiece 13 side than the line connecting the fulcrums 21 and 21. Then, the center of gravity is formed so as to change between the concave portion 28 side and the base 13 side.

Next, the operation of the cartridge tank constructed as described above will be described. When the liquid fuel in the cartridge tank 7 is used up for refueling, first, hold the grip portion 23 of the rotary handle 22 shown in FIG. 5 and pull it up. At this time, the position of the center of gravity G is above the position of the line connecting the fulcrums 21, 21 of the rotary handle 22, that is, on the recess 28 side, so that the main body case 7a is fulcrum 21, 21.
With the axis 1 as the axis, the concave portion 28 side is turned downward and the mouthpiece 13 side is turned upward, and is stopped at the position shown in FIG.

In this state, the concave portion 28 is placed on the floor and the base 1
Remove 3 and fill the cartridge tank 7 with oil. When the liquid fuel becomes full, the position of the center of gravity G comes to be located above the position of the line connecting the fulcrums 21 and 21, that is, to the base 13 side. Therefore, after refueling is completed, close the base 13,
When the cartridge tank 7 is lifted by holding the grip 23 of the rotary handle 22, the main body case 7a moves to the fulcrum 21,
Since the base 13 rotates around 21 and the base 13 is located downward as shown in FIG. 5, the cartridge tank 7 is housed in the heater body in this state. Again, when the oil is exhausted, the position of the center of gravity G of the main body case 7a moves above the position of the line connecting the fulcrums 21 and 21, as shown in FIG.

Therefore, in this embodiment, when the cartridge tank is taken out from the heater main body or stored in the heater main body, a space is formed between the grip portion and the concave portion of the rotary handle, so that the cartridge tank is gripped. You can work safely without the body case hitting your hand. Further, when refueling, the concave portion of the main body case is placed on the floor, so that the stability is good. Further, since the position of the center of gravity moves according to the amount of liquid fuel, it is possible to save the trouble of holding the fully loaded heavy body case by hand and rotating the case.

[0031]

As is apparent from the above description, according to the present invention, a rotation handle having a fulcrum near the center of the cartridge tank is provided, and the cartridge tank is automatically rotated or locked by utilizing its own weight. Since the refueling work is performed by doing so, the refueling and storing work is simple and safe.
