Abstract

PURPOSE:To prevent a wick from lowering excessively and to keep always a good burning state by controlling the lowering of the wick to a preset position that has been raised up to a combustible range by a heating power adjusting mechanism. CONSTITUTION:The 1st operating lever 28 interlocks with an adjusting lever 43 and revolves freely. The wick 5 is lowered by this revolution from the burning position of strong fire down to that of medium burning or weak burning according to the push down of the flame controlling plate 36 and therefore, the burning state of prescribed heating power continues. The burning state can be returned again to strong fire by pushing up the flame controlling plate 36. The flame controlling plate 36 controls the moving range by the oblong hole 53 and always sets the maximum lowering position of the burning wick 5 to a proper preset position. As a result, incomplete combustion due to excessive lowering of the wick 5 does not occur to obtain adequate combustion at all times.

1 is provided with an electrode plate 73 that is electrically connected to a dry battery (not shown), and this electrode plate 13 faces the ignition lever g4, and comes into contact with it as the ignition lever 64 rotates, and the ignition heater 66 is energized. ! A shaft 14 is provided at the end of the racket 68, and one end of a transmission lever 75 is engaged with this shaft 74. A support plate 76 is provided on the inner surface of the substrate 14, and a transmission lever,
An intermediate portion of rs is rotatably supported via a pin 77. The other end of the transmission guard 15 and the intermediate portion of the second operating lever 2# are connected by a connecting strip 1g.

Further, a sedge ring Ig is stretched between the other end of the transmission lever 15 and the support plate 16, and this sedge ring 1# causes the second operating lever 29 to move upward, that is, counterclockwise in the figure, via the connecting line r1. energized.

Next, the operation will be explained. In the combustion standby state,
The first and second operating rays +-is.

2# are each inclined upward with the connecting tube 25 as a fulcrum, and the lamp wick 5 is located at the lower end of the wick guide tube 3. From this state, when the ignition operation plate 35 is pushed down via the knob 37, the second operation lever 29 moves simultaneously in the time σ1 direction against the sliding ring 29, using the connecting cylinder 25 as a fulcrum. Apart from this, the first operating lever 28 is pushed down by a pin 39 provided on the back of the ignition operating plate 35''C/), and rotates integrally with the second operating lever 29. Along with this rotation, The engagement pin 50 of the first handler 28 is first connected to the adjustment lever 43.
This contact makes the adjustment lever 43
is pushed to the left against the sedge ring 48 2, and with this movement the retaining pin 50 passes through the introduction s49, and after passing through, the adjustment lever 43 is moved back to the right by the biasing force of the sedge ring 48, The engagement pin 50 engages with the engagement groove 46 .

After this locking, the locking pin 50 is further lowered, and this lowering causes the adjustment lever 43 to rotate counterclockwise around the support pin 45, and the firepower control plate 36 is pushed up via the connecting lever 42. It will be done. Due to the rotation of the first operation plate 2Be), the operation shaft 11 also moves integrally Kfl, and the wick l is pulled up to the wick holder via the interlocking body 1#, and the wick j is moved to the fire pan part 1111.
C center out. That is, it rises to the combustible region K. 1st
Under condition 1, in which the operation lever 21 of the 120 is pushed down at the lowest 11Kt, the lamp wick JFit is also held at a high ignition position. The bar VTIO and MA are pulled down and one end side is raised. Due to this rise, ignition occurs and d-64 is at the axis LIJ.
With this rotation, the push-up lever σ9 rises, and the combustion cylinder 1ztD-11 times- is pushed up.

The combustion tube 12 is tilted and the portion of the fire pan 11JJ facing the ignition heater d# is opened. Then, as the ignition lever moves 140 times, this lever I4 becomes electric 1i1[
FJK contacts to ignite and energizes the heater 11, and this heater #- enters above the fire pan 11110 to achieve ignition of the lamp wick 5 (by contact and O contact). When the fifth operation lever j1 moves 1111Ihth, the locking lever 31 also rotates integrally with this, and the hook-shaped O locking portion J2 at one end of the locking lever 31 temporarily engages the locking receiving portion 5CK of the interlocking plate 5J of the fire extinguishing mechanism. Touch and pass through it.

After the lamp wick 5 has been ignited, the operator releases the ignition operation plate 35, and this release causes the second operation lever 29 to rotate counterclockwise by the biasing force of the Sgeling r#. move and return to the original position. According to this, the ignition lever 64 and push-up lever 6# are activated.
The combustion cylinder 12 is returned to its original position by the biasing force of 11, and the combustion tube 12 is placed on the fire pan 11JJ in a normal state. As the 20th operating lever 2I returns to rotation, the first operating lever 21
And the locking lever 11% moves counterclockwise Kli by the biasing force of the slider J4, but immediately after that movement, it locks and Δ-JJ
The locking portion J1 locks the locking receiver gigK of the fire extinguishing mechanism, so the amount of movement of the first operation d-18 and the locking lever 11 is suppressed to a very small amount. Then, in conjunction with 70IIIK, the lamp wick 5 is slightly lowered from the ignition position, and is set at the combustion position with high firepower. If this T-trench device is expanded, strong firepower O combustion will continue.

On the other hand, if you want to set the combustion firepower to another medium or short firepower, you can do so by pressing down on the firepower operation board 3#, that is, by pinching the firepower operation board xi and pressing it down via Jl. , whose operation is controlled by the adjustment lever dJ via the connecting lever 41.
The adjustment lever 4J for the K transmission gear moves counterclockwise (B) using the support ring 45 as a fulcrum. The 14-bar lever 43 is connected to the first operation lever 21 by engagement between the engagement groove 4C and the engagement pin J#), and therefore, the first operation lever 21 is adjusted in conjunction with Δ-4JK. Move counterclockwise. 10th operation Leno-ZaO hour hand direction O movement II! Although it is regulated by the folding piece JJK of the company protection lever 11, its movement in the counterclockwise direction is not regulated at all, and it is freely linked to the ζO 10th operation lever 21 line adjustment - 48FC. K11l moves. Then, the wick 5 is lowered from the high power O combustion position to the medium fire power medium low fire power O combustion position <1 according to the amount of depression of the large force operation plate ago, and this changes the combustion state of the set fire power. continue. In addition, when setting the combustion state to high firepower again, the firepower operation panel 36
Do that by pushing up.

The movement range of the firepower control plate 16 is restricted by the elongated hole 5g, so that the lowermost position of the lamp wick 5 during combustion is always set at an appropriate constant position tb, and further lowering is prevented. Therefore, there is no occurrence of incomplete combustion due to lowering the wick 5 too much, and proper combustion can always be obtained.In this embodiment, the height of the wick 5 protruding from the fire pan 11 is set to 8cm, which is a high flame strength. 3- to weak firepower, the difference is 5m1
The lamp wick 5 moves up and down within the D range to adjust the firepower.

In this way, the lamp wick 5 moves in a small width of 5■, but the ζO lamp wick I and the firepower control board j that interlock this
The movement relationship between # and O is that they are the operating levers za and W4f.
Since they are connected by the lever 4J and the connecting lever 42, the firepower control panel IC0SS expands in response to the movement of the lamp wick 5, so that the lamp wick 1 can be finely moved step by step. In this embodiment, the range of movement of the firepower control panel AGO is set to 30 - by magnifying it six times.

In conventional devices of this type, the wick is moved up and down by rotating a dial, but with this type of dial, if you want to move the wick up and down by a large amount, you have to squeeze the dial several times. However, in this example, it is often necessary to turn the dial while adjusting the dial, which makes the operation cumbersome and time-consuming.
The structure is such that the lamp wick I can be moved up and down by the up and down operation of the large-force operating panel jgo, and it has the advantage that the wick I can be efficiently performed in one operation.

When igniting the lamp 810, the wick l is raised from the high-power O combustion position by a distance t above it, but this is due to the arrangement of the locking part J1 in the locking holder ll1-. Once the part is overloaded, when the wick I is pulled down from the ignition position to the high power O combustion position, the O locking III is engaged with the retaining receiver @II to ensure the O locking. is intended. If the timing of the multiple ignition and the locking 0 tie 2 were the same, multiple ignitions could be achieved due to variations in assembly, but the locking between the locking part 5 and the locking receiving part 5# would not be possible. If this is not achieved, there is a risk that the lamp wick 5 will move out of the combustible range and return to its initial position below when the ignition operation plate SSO is released. This is because the timing and the timing of locking are shifted.

Next, extinguishing will be explained. To extinguish the combustion, press down the knob ttX on the manual extinguishing lever #1.
When 2 is pressed down, the fire is manually extinguished, d-13 rotates, and the interlocking plate aX is removed clockwise against the flutter 51 using the bottle 14 as a fulcrum. Locking receiver part II#
The locking lever JJIZ) is released from the locking part J2, and the

Since the evening piece tS' collides with the lower edge of the control lever XaO, the lever tS' is operated and Δ-21 is also rotated counterclockwise together with the locking lever 11. The engagement pin l# of the first operating lever 2J is engaged with the engagement groove 4# of the adjustment lever 4JO, but is disengaged from the engagement groove 4# by the force of turning the operating lever 110 times. By the counterclockwise movement of the first operating lever 210, the lamp wick 5 is pulled down at once and greatly via the interlocking body 1#, thereby achieving instantaneous extinguishment.

If an earthquake occurs during combustion and the seismic loss 52 tilts,
With this pendulum 11c) disk e-, manual fire extinguishing lever #
In the same way as in case 1, the interlocking plate 5J is rotated, so that even in the event of such an earthquake, instant fire extinguishment is carried out and safety is ensured. [Effects of the Invention] As explained above, the present invention According to the above, the combustion heat power is adjusted by lifting the nine lamp wicks up to the combustible range and regulating their descent to a fixed position by moving them up and down (using a fire power adjustment mechanism). This has the effect of ensuring that there is no chance of lowering the temperature too much, thereby reliably preventing the occurrence of incomplete combustion, and ensuring good combustion at all times.
