Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a wick up/down device for a wick type oil combustor.

Conventional technology Generally, this type of oil combustor moves the wick up and down to burn and burn.
The lamp is extinguished, and the lamp wick is moved up and down by vertically moving a lever 53 connected to the lamp wick 51 via a pin 52, as shown in FIG. In the figure, 54 is the pivot point of the lever 5a, and 55 is the pivot point of the lever 5a.
5 is a fuel tank, 56 is a core guide cylinder, 57 is a core outer cylinder, and 58 is a combustion cylinder.

Problems to be Solved by the Invention However, in the oil combustor having the above structure, the stove body has recently been downsized, and the distance e of the lever 53 from the pivot point 54 has become shorter, and the distance e from the pivot point 54 of the lever 5a has become smaller. When the lamp wick 51 is operated, it moves a lot, and when the user wants to slightly adjust the amount of combustion, it is very difficult to make fine adjustments, which poses a problem in terms of usability.

The present invention has been made in consideration of these points, and aims to facilitate fine adjustment of m weight and to improve safety.

Means for Solving the Problems In order to achieve the above object, the present invention includes a manually operated wick up/down mechanism for moving the wick up and down, and a wick up/down mechanism which is normally uncoupled with the above wick up/down mechanism but is connected to the wick up/down mechanism during operation. A core vertical fine adjustment mechanism that engages and drives the core vertically in small increments is provided, and of the rack and pinion that constitute the core vertical fine adjustment mechanism, a tapered portion is provided at the engaging portion of the pinion with the rank. It's Toshide.

Effect of the present invention With the above configuration, the combustion amount can be adjusted in small increments by the wick vertical fine adjustment mechanism, and when the anti-shock fire extinguishing mechanism is activated during the fine adjustment, the rack on the wick vertical mechanism side will adjust the wick vertical fine adjustment mechanism. It slides on the pinion on the side to ensure a secure transition to the extinguishing state.

EXAMPLES The following examples will be explained using FIGS. 1 to 8. First, in FIGS. 3 and 4, 1 is a core guide tube, 2 is a core outer tube arranged with a gap around the outer periphery of the core guide tube 1, and 3 is a space between the core guide tube 1 and the core outer tube 2. 4 is a combustion tube (see FIG. 8) that burns the fuel vaporized from the wick 3.

Next, a manually operated wick up and down mechanism 5 that moves the lamp wick 3 up and down.
This will be explained using FIGS. 3 and 4 as well. First, 6 is a wick up/down lever that moves the wick 3 up and down.
and one end thereof is linked through a suitable linking means. This core up/down lever 6 is attached to a pin 8 (first
(see figure), it is pivotably supported midway.

Reference numeral 9 denotes an ignition lever which is pivotally supported on the wick upper and lower substrate 7 by a pin 8 together with the wick upper and lower lever 6, and one end of the lever 9 is adapted to actuate an ignition device (not shown) by heat to ignite the lamp wick a. After ignition, it automatically returns to its original position. Reference numeral 10 denotes a core upper and lower body which, like the ignition lever 9, is pivotally supported on the core upper and lower substrate 7 by a pin 8 together with the core upper and lower lever 6, and is adapted to be linked with the core upper and lower lever 6 by appropriate means. 11 is the core upper and lower body 1
A spring that biases ° toward the upper position (lower wick position).
It is a hook between the end of the core upper and lower bodies 10 and the core upper and lower substrates 7. Reference numeral 12 designates a lock plate that holds the wick upper and lower bodies 1o in a lower position (wick raised position), and is rotatably supported by a pin 120. This lock plate 12 has a long hole 14 through which the pin 1a implanted in the core upper and lower bodies 10 is inserted, and a locking portion 14m is formed at the end of the long hole 14 to lock the pin 13. It looks like this. That is, when the wick up/down lever 6 is pressed down (in the wick upward direction), the wick up/down body 10, which is linked with the wick up/down lever 6 by appropriate means, rotates downward (the pin 13 of the wick up/down body 1° is inserted into the elongated hole 14).
When the pin 13 descends along the long hole 14 and reaches the end of the elongated hole 14), the pin 13 fits into the locking portion 14a and locks the upper and lower core bodies 10 at that position despite the biasing force of the spring 11. Become. 15 is a leaf spring attached to the lock plate 12, and 16 is a vibration extinguishing weight connected to the leaf spring 15 via a chain 17, which is erected on a pedestal 18 provided on the core upper and lower substrates 7. . This weight 16 swings when an earthquake occurs and rotates the leaf spring 15, that is, the lock plate 12 via the stopper 17. As a result, the pin 13 is released from the locking portion 14m of the elongated hole 14,
The upper and lower core bodies 10 are rotated upward by the biasing force of the spring 11.

At this time, since the wick upper and lower bodies 10 are linked with the wick up and down lever 6, the wick up and down lever 6 also rotates upward, and the wick 3 descends to extinguish the fire. At this time, pin 1a has returned to the upper position.
presses the leaf spring 15 and pulls the weight 17, returning the fallen weight 16 to its original state.

That is, the core upper and lower bodies 10 described above. The spring 11, the lock plate 12, the leaf spring 15, the vibration extinguishing weight 16, the chain 17, and the like constitute a seismic extinguishing mechanism 16A. Reference numeral 19 denotes an emergency fire extinguishing button, which is pivotally supported on a fire extinguishing button support shaft 19-, and is adapted to rotate the lock plate 12 in the same manner as the weight 16.

Next, the core vertical fine adjustment mechanism 20 will be explained using FIGS. 1, 2, and 5 (4), @), and (C). First of all, 21 stands for l

is installed in one piece. That is, the sublever 21 makes the same rotational movement in conjunction with the rotational movement of the core up/down lever 6, and the rack 23 attached to the sublever 21 also makes the same rotational movement. Reference numeral 25 denotes a base body, which is integrally attached to the core upper and lower substrates 7. The base body 25 includes a fulcrum shaft 26a for centering and a fulcrum shaft 2 for centering
It has 6b. 27 is a centering operation body, and its bearing part 2

It is rotatably inserted into the 6m length. Reference numeral 28 denotes a centering operation body, and its bearing portion 28m is rotatably fitted into the centering fulcrum F$26b in the same way as the centering operation body 27.

Reference numeral 29 denotes a centering slide, and 30 a centering slide. The centering slide 29 is slidably fitted into a bearing 31a provided on the base body 25, and the centering slide 29 is a centering slide. 30 is slidably fitted into the bearing 31b. A2 is a centering pinion provided at a position facing the rack 23, which has a tapered portion 32 and is pivotally supported on the centering slide 29 by a support shaft 33. Numeral 34 is a centering pinion provided at a position facing the rack 23, like the centering pinion 32, and the tapered portion 34a is pivotally supported on the centering slide 30 by a support shaft 35. 36 is a slide return spring for centering, and the base body 25

Reference numeral 38 denotes a centering slide return spring, which is attached to the spring support shaft 37b, with one end engaged with the support shaft 35 and the other end engaged with the spring receiver 38b. Reference numeral 39 denotes a centering pinion return spring attached to the support shaft 33, one end of which engages with the centering slide body 29 and the other end engaged with the centering pinion 32. Reference numeral 40 denotes a center lowering pinion return spring attached to the support shaft 35, one end of which is engaged with the center lowering slide body 30, and the other end is engaged with the center lowering pinion 34. The core lowering slide body 30 explained above. The clutch mechanism 24 is composed of the support shaft 35, the centering pinion 34, the centering slide return spring 38, the centering pinion return spring 40, and the rack 23.

Next, the operation of the oil combustor wick up-and-down device configured as described above will be explained below.

First, from the state before use as shown in Figures 1 and 3,
When pressed down, the lamp wick 3 rises to the combustion position as shown in FIG. 4, and the ignition device (
(not shown) is activated to ignite the lamp wick 3. The ignition lever 9 then returns to its original state. At this time, the sublever 21 that is integrally attached to the lead up/down lever 6 also performs the same rotational movement as the lead up/down lever 6, and the rack 23 attached to the sublever 21 is used to raise and lower the lead vertical fine adjustment mechanism 20. It comes to face pinions 32 and 34.

In the above manner, the centering and dotting operations are completed.

Once combustion begins, the amount of combustion can be adjusted by vertically moving the wick up/down lever 6. Next, the amount of combustion can be adjusted by operating the wick up/down fine adjustment mechanism 2o as shown in FIG. 5(A).
This will be explained using FIG. 5(C). First, as shown in FIG. 5(A), when the lamp wick 3 is set in the combustion position, the rack 23 is set in a position facing the wick raising pinion 32 and the wick lowering pinion 34 as described above. In order to reduce the amount of combustion, as shown in FIG. 5(C), when the core lowering operating body 28 provided on the base body 25 is operated in the direction of the arrow Ss force, the abutment piece 28b protrudes from the core lowering slide body 30. Piece 3
Press 0m, and the core lowering slide body 30 is the base body 25.
The centering pinion 34, which slides like an FJI in a bearing 311) provided in the center and is pivotally supported by the centering slide 30, engages with the rack 23, which is normally in an uncoupled state, and moves in the direction of arrow 0. The rack 2a is rotated to push up the rack 2a in the direction of arrow E.

As a result, the wick up/down lever 6 is also pushed up in the direction of arrow E via the sub-lever 21 to which the rack 23 is attached, so that the wick a is lowered. At this time, the dimensions of the centering pinion 34 are such that when the centering operation body 2B is pushed once, the centering pinion 34 moves only one tooth of the rack 23. The core lowering pinion 34 is the rack 23
After feeding - number of teeth, the core lowering slide body 34 releases the core lowering slide return spring 38 which is engaged with the support shaft 35.
Due to the applying force, the core lowering operation body 28 returns to its original state as shown in FIG. 5(A), and the center lowering pinion 34 and the rack 23 are disengaged from each other. Further, the core lowering pinion 34 returns to its original state because the core lowering pinion return spring 40 is always biased in the direction of arrow G. That is, by the action of the clutch mechanism 24, the link between the lead up/down mechanism 5 and the lead up/down lever 6 is disconnected, and the original state is restored.

By the above-described operation, the lamp wick 3 can be lowered little by little, and the amount of combustion can be reduced little by little.

Next, when increasing the combustion amount, the core raising operation body 27
All you have to do is operate. That is, as shown in Fig. 5 @), when the centering operation body 27, which is rotatably fitted into the centering fulcrum shaft 26, is operated in the direction of the arrow sb force, the contact piece 27b moves into the centering slide body - 29, the centering slide 29 slides in a bearing 310 provided on the base body 25 in the direction of arrow Fb, and the centering pinion 32 pivotally supported by the centering slide 29 moves normally. engages with the uncoupled rack 23 and rotates in the direction of arrow H,
The rack 23 is pushed down in the direction of the arrow J, that is, the wick up/down lever 6 is pushed down in the direction of the arrow, and the lamp wick 3 rises. At this time, just like when lowering the center, if you press the center-up operation body 27 once, the center-up pinion 32
are set in a dimensional relationship such that only one tooth of the rack 23 is advanced. When the centering pinion 32 finishes feeding one tooth of the rack 23, the centering slide 29 is moved by the biasing force of the centering slide return spring 36 engaged with the support shaft 33 as shown in FIG. At the same time that the centering operation body 27 returns to its original state, the centering pinion 32 and the rack 23 are disengaged from each other. Further, the centering pinion 32 returns to its original state because the centering pinion return spring 39 is always biased in the direction of the arrow. - Next, FIGS. 6(A) to 6(A) show the case where the seismic fire extinguishing weight 16 of the anti-seismic fire extinguishing mechanism 16A swings while the core up/down fine adjustment mechanism 20 is performing the core raising/lowering operation. Figure 6 (D
). First, Fig. 6 (A
). When the weight 16 swings, the pin 13 implanted in the core upper and lower bodies 10 separates from the locking portion 14m of the elongated hole 14 formed in the lock plate 12 and escapes in the direction of arrow N, thereby locking the core. The upper and lower bodies 10 and the wick up/down lever 6 linked thereto try to rotate upward (in the wick lowering direction). That is, as the core up/down lever 6 attempts to rotate upward, the rack 23 also attempts to rotate in the direction of arrow M. However, since the rack 23 and the centering pinion 32 are in mesh with each other, the centering pinion 32
attempts to stop the rack 23 from pivoting upward. If the bottom surface of the tapered part 32m of the centering pinion 32 is in a substantially horizontal state, the force of the rack 23 to rotate upward will cause the centering pinion 32 to rotate as shown in FIG. , only vertical force 2 acts, and the core raising pinion 32 and rack 23 are not disengaged.In other words, the core up/down lever cannot be rotated upward.If the user performs the core raising operation during combustion, Even though the weight 16 swung during the
If the wick lifting pinion 32 and the rack 2a are disengaged and the wick up/down lever 6 cannot be rotated upward, that is, the wick 3 cannot be lowered, combustion will continue in that state, and the user will not be able to use any extinguishing means. Losing it can be extremely dangerous. However, in the product according to the present invention, as shown in FIG. 6(C), the lower surface of the pinion 32 is inclined upward to form a tapered portion 32m, so that the pinion 32 and the rack 23 are in mesh with each other. As shown in Figure 6), as the rack 23 attempts to rotate in the Q direction, a force W acts on the tapered portion 32m of the centering pinion 32, and a vertical component force W1 is applied to the centering pinion 32. A component force W2 in the detachment direction acts on the rack 23. Therefore, the rack 2a can easily slide on the tapered portion 32a of the centering pinion 32,
The two become disengaged.

Therefore, the wick 3 descends and extinguishes the fire. This is weight 1
The same effect can be obtained not only when 6 swings, but also when the user accidentally activates the extinguishing button during the core raising operation.

Next, if the vibration extinguishing weight 16 of the anti-seismic extinguishing mechanism 16A swings during the wick lowering operation, the rotating direction of the rack 23 (wick lowering direction) is indicated by the arrow as shown in FIG. 5(C). E
Since the rotational movement direction of the centering pinion 34 is in the direction of the arrow 0, the centering pinion 34 rotates in the direction away from the rack 23. If the weight 16 swings and the rack 2a attempts to rotate in the E direction while the center lowering pinion 34 is in the engaged state, the rack 23 easily engages the center lowering pinion a.
The lamp wick 3 can be freely lowered by inserting the lamp 4 in the direction of the arrow O and sliding it on the tapered part 34a.

As described above, in this combustor, if the vibration extinguishing weight 16 of the anti-seismic extinguishing mechanism 16A is activated during the wick raising/lowering operation by the wick up/down fine adjustment mechanism 20, or the user presses the extinguishing button by mistake. The lamp wick 3 can be reliably extinguished even when the fire occurs.

In addition, in this embodiment, the core raising/lowering pinion 32.34
The rack 23, which is centered so as to face the wick, is set to a length that is located not over the entire range of the vertical stroke of the wick, but only a part of it, that is, within a range in which combustion is maintained normally. In other words, the position of the lowest tooth 23m of the rack 23 is the lamp wick 3.
The core lowering pinion 34 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 tooth 23b of the rack 23 is positioned so that the wick raising pinion 32 cannot send the teeth of the rack 23 above a height at which the wick 3 can perform normal combustion.

Therefore, by repeating the operation of the wick raising and wick lowering operation bodies 27 and 28 several times, if the wick raising and wick lowering pinions 32 and 34 send the lowermost tooth 23 or the uppermost tooth 23b, the wick 3 will no longer be activated. It is no longer possible to move it up and down, allowing you to fine-tune the amount of combustion with peace of mind.

The eighth factor shows an example of an oil combustor using the wick up/down device of this embodiment, and 41 is a door attached to the base body 25;
42 is an ignition knob attached to the tip of the ignition lever 9, and 43 is a wick up/down knob attached to the tip of the wick up/down lever 6. To use the moss, first open the door 41.
Open the wick and push down the ignition knob 42 and wick upper and lower knobs 43 on the inside to ignite the wick 3. When combustion begins, the wick upper and lower knobs 43 or the wick lowering operation body 28 and the wick raising operation body 27 are used to light the wick 3. It adjusts the amount of combustion.

Next, another embodiment of the core vertical fine adjustment mechanism 20 will be explained using FIG. 7. In the figure, 50 is a fine adjustment base;
1m is a bearing for centering, and 51b is a bearing for centering. Reference numeral 52 designates a centering button, which has a slide shaft portion 52m that slides within the centering bearing portion 51a, and has a slide shaft portion 52m that slides within the centering bearing portion 51a.
A centering pinion 32 having a tapered portion 32a pivotally supported by a centering pinion shaft 53 is incorporated in the centering pinion 32.

Reference numeral 54 denotes a centering button return spring interposed between the fine adjustment base 50 and the centering button 52, which always applies a force in the direction of the arrow. Reference numeral 55 denotes a core lowering button, which has a slide shaft portion 55a that slides within the core lowering bearing portion 51b, and the slide shaft portion 55- has a taper portion 34a pivotally supported on a core lowering pinion shaft 56. A pinion 34 is incorporated.

Reference numeral 57 denotes a core lowering button return spring interposed between the fine adjustment base 50 and the core lowering button 55, which always applies a force in the direction of arrow M.

In the above configuration, when the centering button 52 is pressed, the centering pinion 32 and rack 23 are moved as shown in Fig. 5@)
Perform a movement similar to that shown in
2 feeds the teeth of the rack 2a one by one. Also, when the core lowering button 55 is pressed, the core lowering pinion 34 and the rack 2
3 performs a movement similar to that shown in FIG. 5C), and the centering pinion 34 advances the teeth of the rack 23 one by one. In addition, the core raising button 52 and the core lowering button 5
5 while operating the vibration extinguishing weight 1 of the anti-seismic extinguishing mechanism 16A.
As in the first embodiment, the lamp wick 3 can be reliably extinguished even if the lamp 6 is activated or the user presses the extinguishing button by mistake.

As described above, this embodiment provides the same effects as those of the above-described embodiments, but has the advantage of simplifying the configuration because the button and the slide shaft can be integrated.

The above-mentioned embodiment is shown as an example of achieving the object of the present invention, and any structure may be used as long as the object of the present invention is achieved.

Effects of the Invention As is clear from the description of the embodiments, the core raising and lowering device of the present invention can raise and lower the core not only by the lead raising and lowering mechanism but also by the fine adjustment mechanism for raising and lowering the lead. After that, you can make small calorie adjustments using the fine vertical adjustment mechanism. In addition, since the lead up/down mechanism and the fine adjustment mechanism are normally uncoupled, if a motor is used as the drive source for the lead up/down fine adjustment mechanism, even if this motor breaks down, the lead up/down mechanism will still be able to perform the lead up/down masterpiece. . Furthermore, even if the anti-shock extinguishing mechanism is activated during the wick raising and wick lowering operations using the wick vertical fine adjustment mechanism, the wick can be reliably lowered and extinguished, resulting in high safety.
