A clutch mechanism 24 is constituted by 6, 38, core raising / lowering pinion return springs 39, 40, and rack 23.

Next, the operation of the core lifting device for an oil combustor configured as described above will be described below.

First, from the state before use in FIGS. 1 and 3 to the core up-down lever 6
4 is pushed down, the wick 3 rises at the combustion position as shown in FIG. 4, and an ignition device (not shown) is operated via the ignition lever 9 to ignite the wick 3. Then, the ignition lever 9 returns to the original state. At this time, the core up / down lever 6
The sub-lever 21, which is integrally attached to the
The rack 23 attached to the sub-lever 21 faces the core raising / lowering pinions 32, 34 of the core vertical fine adjustment mechanism 20 by performing the same rotational movement as.

The core raising / ignition operation is completed as described above. When the combustion starts, the amount of combustion can be adjusted by moving the above-mentioned core up-down lever 6 up and down. Regarding the adjustment of the amount of combustion by operating the core up-and-down fine adjustment mechanism 20, see FIGS. It demonstrates using. First, as shown in FIG. 5A, when the wick 3 is set to the combustion position, the rack 23 is set to the position facing the core raising pinion 32 and the core lowering pinion 34 as described above. When reducing the amount of combustion, as shown in FIG. 5C, when the operation body 28 for lowering the core provided on the base body 25 is operated in the direction of the arrow Sa, the contact piece 28b causes the protruding piece 30a of the slide body 30 for lowering the core. The core lowering slide body 30 slides inside the bearing 31b provided on the base body 25 like Fa, and the center lowering pinion 34 pivotally supported by the center raising slide body 30 is normally in a non-coupling state. It engages with a certain rack 23 and rotates as it is in the direction of arrow D, and pushes up the rack 23 in the direction of arrow E. As a result, the sub-lever 21 to which the rack 23 is attached is attached.
The core up / down lever 6 is also pushed up in the direction of the arrow E via, and the wick 3 is lowered.
At this time, if the operation body 28 for lowering the core is pressed once, the core lowering pinion is pressed.
The size of the rack 34 is such that only one tooth of the rack 23 is fed. When the center lowering pinion 34 finishes feeding one tooth of the rack 23, the center lowering slide body 34 is moved by the urging force of the center lowering slide return spring 38, which is engaged with the support shaft 35, as shown in FIG.
When the core lowering operation body 28 is returned to the original state as well as returning to the original state shown in (3), the engagement between the core lowering pinion 34 and the rack 23 is disengaged. Further, the core lowering pinion 34 returns to the original state because the core lowering pinion return spring 40 is always biased in the direction of the arrow G. That is, by the action of the clutch mechanism 24, the linkage with the core up / down lever 6 of the core up / down mechanism 5 is disconnected, and the original state is restored. By the above operation, the wick 3 can be lowered in small steps, and the combustion amount can be gradually reduced.

Next, in the case of increasing the combustion amount, it is sufficient to operate the core raising operation body 27. That is, as shown in FIG. 5B, the center-raising operation body 2 rotatably fitted in the center-lowering fulcrum shaft 26a.
When 7 is operated in the direction of the arrow Sb, the contact piece 27b pushes the protruding piece 29a of the centering slide body 29, and the centering slide body 29 slides in the bearing 31a provided on the base body 25 as shown by the arrow Fb. Moved and the center-raising pinion pivotally supported by the center-raising slide 29.
Normally, 32 is engaged with the rack 23 which is normally in a non-coupling state and rotates in the direction of arrow H as it is, and pushes down the rack 23 in the direction of arrow J. That is, the core up / down lever 6 is pushed down in the direction of arrow J, so that the wick 3 is raised. At this time, as in the case of lowering the core, when the core raising operation body 27 is pushed once, the core raising pinion 32 has such a dimensional relationship that only one tooth of the rack 23 is fed. When the center lifting pinion 32 finishes feeding one tooth of the rack 23, the center lifting slide body 29 moves to the spindle 33.
5A is returned to the original state by the urging force of the center-raising slide return spring 36 which is engaged with the center-raising pin 27 and the center-raising pinion 32 and the rack.
23 mesh disengages. Further, the center-raising pinion 32 returns to its original state because the center-lowering pinion return spring 39 is constantly urged in the direction of arrow K.

Here, the rack 23 set to face the above-mentioned core raising / lowering binions 32, 34 is not a whole region of the core vertical stroke but a part thereof, that is, within a range where combustion is normally maintained,
For example, the exhaust gas characteristic (CO / CO2) is set to a length that is located only within the range that falls within the JIS standard. Ie rack
The position of the lowermost tooth 23a of 23 is set to a position where the core lowering pinion 34 cannot feed the teeth of the rack 23 below the height at which the wick 3 can normally burn. Similarly, the uppermost teeth 23b of the rack 23 are positioned so that the centering pinion 32 cannot feed the teeth of the rack 23 beyond the height at which the wick 3 can normally burn. Therefore, when the operation of the core raising / lowering operating bodies 27, 28 is repeated several times and the center raising / lowering pinions 32, 34 send the lowermost tooth 23a or the uppermost tooth 23b, the wick 3 is moved up and down further. It can no longer be moved, and the amount of combustion can be finely adjusted with peace of mind.

FIG. 7 shows an example of an oil combustor using the core lifting device of the present embodiment. 41 is a door attached to the base body 25, and 42 is a door.
Is an ignition knob attached to the tip of the ignition lever 9, 43

As the operation procedure of the user, first, open the door 41 and push up the ignition knob 42 and the core upper and lower knobs 43 inside the door 41 to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the core lowering Operating body 28 and operating body 27 for centering
The combustion amount is adjusted by.

Next, another embodiment of the core vertical fine adjustment mechanism 20 will be described with reference to FIG. In the figure, 50 is a fine adjustment base, 51a is a core-raising bearing portion, and 51b is a core-lowering bearing portion. 52 is a center-up button, which has a slide shaft portion 52a that slides in the center-up bearing portion 51a, and the slide shaft portion 52a has a center-up pinion shaft 53.
