There is a problem that the wick 51 moves largely by operation, and when the user tries to adjust the combustion amount a little, it is difficult to make fine adjustment, and in terms of usability it is just a step away.

The present invention has been made in view of the above circumstances, and an object thereof is to facilitate fine adjustment of the combustion amount and to improve safety.

Means for Solving the Problems In order to achieve the above object, the present invention provides a manually operated core up-and-down mechanism for vertically moving a wick, and a core up-and-down mechanism when not normally linked to the core up-and-down mechanism. A structure is provided in which a core up-down fine adjustment mechanism for engaging and driving this in small increments is provided, and a taper portion is provided in a rack and pinion engaging part of the pinion rack with respect to the rack up-down fine adjustment mechanism. There is.

The present invention allows the amount of combustion to be adjusted in small steps by the core up-down fine adjustment mechanism according to the above-mentioned configuration, and when the anti-earthquake fire extinguishing mechanism is activated during the fine adjustment, the rack on the core up-down mechanism side has the core up-down fine adjustment mechanism side. It will slide on the pinion and will surely transition to the fire extinguishing state.

Example An example will be described below with reference to FIGS. 1 to 8. First, in FIGS. 3 and 4, 1 is a core guide portion, 2 is a core outer cylinder disposed around the outer periphery of the core guide portion 1 with a gap, and 3 is a space between the core guide cylinder 1 and the core outer cylinder 2. The wicks 4 which are vertically movably mounted on the wicks 4 are combustion tubes (see FIG. 8) for burning the fuel vaporized from the wicks 3.

Next, a manually operated core up / down mechanism 5 for moving the core light 3 up and down.
The same will be described with reference to FIGS. 3 and 4. First, 6 is a wick up / down lever for moving the wick 3 up and down.
And one end thereof are linked to each other via a suitable linking means. This core up-down lever 6 is provided with a pin 8 (first

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 to 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 sub-lever 21 integrally attached to the core up-down lever 6 also performs the same rotational movement as the core up-down lever 6, and the rack 23 attached to the sub-lever 21 raises and lowers the center of the core up-down fine adjustment mechanism 20. It comes to face the pinions 32 and 34.

The core raising / ignition operation is completed as described above. When the combustion is started, the amount of combustion can be adjusted by the vertical movement of the core up / down lever 6.
Fig. 5 (A) -Fig. 5 for adjusting the combustion amount by operating the
An explanation will be given using (C). First, as shown in FIG. 5 (A), 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 combustion amount, as shown in FIG. 5 (C), when the core lowering operation body 28 provided on the base body 25 is operated in the direction of arrow Sa, the contact piece 28b is contacted.
Pushes the protruding piece 30a of the core lowering slide body 30, and the core lowering slide body 30 has a bearing 31b provided on the base body 25.
The inside lowering pinion 34, which slides like Fa inside and is pivotally supported by the centering slide body 30, engages with the rack 23 which is normally in the non-coupling state and rotates in the direction of arrow D as it is. 23 is pushed up in the direction of arrow E. As a result, the sub lever 21 to which the rack 23 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, when the core lowering operation body 28 is pushed once, the core lowering pinion 34 has such a dimensional relationship 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 moves the support shaft 35.
5A is returned to the original state by the urging force of the core lowering slide return spring 38 which is engaged with the core lowering operation body 28, and the core lowering pinion 34 is returned to the original state.
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, when increasing the combustion amount, the operation body 27 for raising the core
You can operate. That is, as shown in FIG. 5 (B), when the center-raising operation body 27 rotatably fitted to the center-lowering fulcrum shaft 26a is operated in the direction of arrow Sb, the contact piece 27b moves the center-raising slide body 29. The protrusion 29a is pushed, the centering slide 29 slides in the bearing 31a provided on the base body 25 as shown by the arrow Fb, and the centering pinion 32 pivotally supported by the centering slide body 29 is normally It engages with the rack 23 in the 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, pushes down the lead up / down lever 6 in the direction of arrow J, so that the wick 3 rises. Will be done. At this time, the core-raising pinion 32 has such a dimensional relationship that only one tooth of the rack 23 is fed when the core-raising operation body 27 is pushed once as in the case of the core lowering. When the center-raising pinion 32 finishes feeding one tooth of the rack 23, the center-raising slide 29 is shown in FIG. 5 (A) by the urging force of the center-raising slide return spring 36 which is engaged with the support shaft 33. While returning to the original state, the centering operation body 27 also returns to the original state, and the centering pinion 32 and the rack 2
The mesh of 3 is disengaged. Further, the core-raising pinion 32 returns to its original state because the core-lowering pinion return spring 39 is constantly urged in the direction of arrow K.

Next, a case in which the seismic extinguishing weight 16 of the anti-seismic fire extinguishing mechanism 16A swings while performing the core up / down operation by the core up / down fine adjustment mechanism 20 is shown in FIGS. This will be described with reference to FIG. First, FIG. 6 (A) shows the case where the vibration extinguishing weight 16 swings during the centering operation.
When the weight 16 swings, as described above, the pin 13 planted in the core upper and lower body 10 is disengaged from the locking portion 14a of the elongated hole 14 formed in the lock plate 12 and escapes in the direction of the arrow N, thereby The upper and lower bodies 10 and the core up-and-down lever 6 linked to the upper and lower bodies 10 try to rotate in the upward direction (the direction in which the wick descends). That is, the rack 23 also tries to rotate in the direction of arrow M as the core up-down lever 6 tries to rotate upward. However, since the rack 23 and the center-raising pinion 32 are in mesh with each other, the center-raising pinion 32 is in the rack 2
3 tries to stop trying to rotate upwards. Now, when the lower surface shape of the tooth top taper portion 32a of the center-raising pinion 32 is in a substantially horizontal state, the center-raising pinion 32 does not move to the center-raising pinion 32 due to the force to rotate the rack 23 upward as shown in FIG. 6 (B). , Only the vertical force Z acts,
The engagement between the centering pinion 32 and the rack 23 cannot be disengaged. That is, it is possible to surely extinguish the wick 3 even when the wick is vertically placed.

Further, in this embodiment, the core raising / lowering pinions 32, 34
The rack 23 set so as to oppose is set to have a length which is located not in the entire area of the vertical stroke of the core but in a part thereof, that is, in the range where combustion is normally maintained. That is, the position of the lowermost tooth 23a of the rack 23 is set to the wick 3
Is below the height at which normal combustion can be performed.
Is in a position where the teeth of the rack 23 cannot be fed. Similarly, the uppermost teeth 23b of the rack 23 are positioned such 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 operation bodies 27/28 is repeated several times and the core 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. 8 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,
Reference numeral 42 is an ignition knob attached to the tip of the ignition lever 9, and 43 is a core up / down knob attached to the tip of the core up / down lever 6. As the operation procedure of the user, first, the door 4
1 is opened and the ignition knob 42 and the core upper and lower knobs 43 inside thereof are pushed down to ignite the wick 3, and when combustion starts, the core upper and lower knobs 43 or the core lowering operation body 28
The amount of combustion is adjusted by the operation body 27 for raising the core.

Next, another embodiment of the core vertical fine adjustment mechanism 20 will be described with reference to FIG. 7. In the figure, 50 is a fine adjustment base and 51 is a fine adjustment base.
Reference numeral a is a core-raising bearing portion, and 51b is a core-lowering bearing portion.
Reference numeral 52 denotes a lead-up button, which has a slide shaft portion 52a that slides in the lead-up bearing portion 51a.
A core-raising pinion 32 having a taper portion 32a pivotally supported by the core-raising pinion shaft 53 is incorporated in this.
Reference numeral 54 denotes a center-up button return spring interposed between the fine adjustment base 50 and the center-up button 52, which constantly applies force in the direction of arrow L. A core lowering button 55 has a slide shaft portion 55a that slides in the core lowering bearing portion 51b, and the slide shaft portion 55a has a taper portion 34a pivotally supported by a core lowering pinion shaft 56. 34 is incorporated. 57 is the fine adjustment base 50 and the core lowering button 5
With the center-down button return spring interposed between 5, the arrow M is always
The force is urged in the direction.

When the center raising button 52 is pressed in the above configuration, the center raising pinion 32 and the rack 23 are the same as those shown in FIG.
Perform the same movements as shown in, and move the centering pinion 3
2 sends the teeth of the rack 23 one by one. Also, when the center lowering button 55 is pressed, the center lowering pinion 34 and the rack 2
3 performs the same movement as that shown in FIG. 5 (C) described above, and the centering pinion 34 feeds the teeth of the rack 23 one by one. In addition, core up button 52 / core down button 5
Weight for vibration extinguishing of seismic extinguishing mechanism 16A while operating 5
It is the same as in the first embodiment that the wick 3 can be extinguished reliably even if 6 is activated or if the user accidentally presses the fire extinguishing button.

As described above, in this embodiment, the same effect as that of the above-described embodiment can be obtained, but since the button and the slide shaft portion can be integrated, there is an advantage that the structure can be simplified accordingly.

The above-mentioned embodiment is shown as an example for achieving the object of the present invention, and may be configured in any manner as long as it achieves the object of the present invention.

EFFECTS OF THE INVENTION As is clear from the above description of the embodiments, the core lifting device of the present invention can move the core up and down not only by the core lifting mechanism but also by the core lifting fine adjustment mechanism. After that, you can adjust calories in small increments with the fine adjustment mechanism. In particular, the above combustion amount adjustment can be made in small steps, so the combustion amount can be adjusted digitally, that is, the core height changes almost quantitatively for each step, so that the user can easily adjust the combustion amount. By becoming able to know in, usability is dramatically improved. Further, since the core up / down mechanism and the fine adjustment mechanism are usually not linked, when the motor is used as the drive source of the core up / down fine adjustment mechanism, the core up / down mechanism can perform the core up / down operation even if the motor fails. . Further, even when the anti-earthquake fire extinguishing mechanism is activated during the operation of raising and lowering the core by the above-mentioned core up-down fine adjustment mechanism, the wick can be surely lowered to extinguish the fire, which is highly safe.
