DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wick elevating device for a liquid fuel combustion device.

[0002]

2. Description of the Related Art An oil stove will be described as an example of a conventional liquid fuel combustion apparatus with reference to the drawings. FIG.
1 is an external perspective view of a fuel tank of an oil stove. The oil stove core elevating device 100 includes an elevating unit 110, an earthquake-resistant automatic fire extinguishing unit 120, and a residual oil display unit 140. The wick 12 of the oil stove can be moved up and down by an elevating unit 110, and the combustion state is controlled by adjusting the amount of protrusion of the wick 12 from the upper end of the core inner cylinder 11. That is, the operation lever 11
By raising and lowering 1, the wick 12 is raised and lowered within the range between the fire extinguishing position and the burning position, and by operating the fire extinguishing lever 114, the wick 12 in the burning position is lowered to the fire extinguishing position. The wick 12 is placed on the upper surface of the main body 10 with its end immersed in petroleum in a fuel tank formed in the main body 10. The earthquake-resistant automatic fire extinguishing unit 120 lowers the wick 12 at the burning position to the fire extinguishing position when vibration exceeding the safety standard is applied to the main body 10 due to an earthquake or impact.

[0003] The residual oil display section 140 is constructed separately from the elevating section 110 and the earthquake-resistant automatic fire extinguishing section 120.
And a display spring 142 and a display plate 143. The display lever 141 is formed to bend in a substantially elliptical shape. The bent portion is pivotally supported so as to be pivotable, and the rear end portion is provided with an action portion 141A that abuts the supply tank 20, and the front end portion is provided with "refueling". It has a display panel 143 for displaying. The display spring 142 displays a predetermined item when the oil supply tank 20 filled with a certain amount of oil is mounted on the main body 10, and when the oil tank 20 is almost empty, the display lever 142 is biased by an urging force.
141 is pushed up and "refueling" is displayed.
When the refueling tank 20 is mounted on the main body 10,
The fire-extinguishing fire lever 150 constituting 0 is depressed against the urging of the spring 151, and the fire extinguishing section 120 can be set in the elevating section 110 and the seismic resistance.

[0004]

Is pulled back by the compression spring 126 via the chain 124 to return to the original position, that is, the upright state.

The display unit 130 includes a display lever 131 and a display plate.
132 and a display spring 133 are included. Display lever 131
When the refueling tank 20 is removed when the wick 12 is in the combustion position, the wick 12 is automatically lowered to the fire extinguishing position,
It is interposed between the vertical wall of the substrate 14 and the operation plate 115.
The display lever 131 has an operating portion 131A rotatably fitted on the outer periphery of the bearing pin 14C, and extends rearward from the operating portion 131A, and has a rear end located above the oil inlet 20A of the oil supply tank 20. Arm section 131B set to perform
An arm 131C extending forward from 131A and having a display plate 132 at the front end is integrally formed. At the tip of the arm 131B, a detection plate 131D that protrudes horizontally to the right is provided, and the refueling tank 20 mounted on the main body 10 comes into contact with the detection plate 131D to detect the amount of oil. Also, the detection plate 13
Between 1D and the action portion 131A, a projection 131E horizontally protruding leftward in the opposite direction to the detection plate 131D is provided,
The tip of the fire extinguishing lever 114 when the display lever 131 swings
It comes into contact with 114F.

The display plate 132 is attached to the front end of the display lever 131, and the characters "fire extinguishing", "refueling" and "ignition possible" are written from the upper part to the lower part. The character is the main body 1
0 can be visually confirmed through a display window 134 of an operation unit 133 provided on the front of the camera. In addition, the above-mentioned "fire extinguishing"
Is automatically extinguished by removing the refueling tank 20
It indicates that In addition, the above-mentioned "refueling"
Is almost empty after the oil in the refueling tank 20 is consumed.
It indicates that refueling is required when Sa
In addition, the above-mentioned "ignition possible" indicates that the oil in the refueling tank 20 is
It indicates that there is a certain amount or more.

The arm portion 131C is swingably inserted through a cut-and-raised portion 14D provided in a vertical portion of the substrate 14, thereby preventing the display lever 131 from rattling.

Next, the operation of the lead lifting device according to the present invention will be described. When the refueling tank 20 containing a certain amount of oil is attached to the main body 10, the lower part of the refueling tank 20 pushes down the arm 131B of the display lever 131, and the seismic resistant automatic fire extinguishing unit 120 can be set. At the same time, the characters "ignition possible" on the display panel 132 are displayed on the display window 134.

When the operating lever 111 is pushed down, the operating pin 115B is locked by the locking portion 114B of the fire extinguishing lever 114,
The earthquake-resistant automatic fire extinguishing unit 120 is set. Fine adjustment pin 116A
Are engaged with the elongated holes 113A of the connecting plate 113,
3 is also set. With the movement of the fine adjustment pin 116A, the ascent of the core 12 is completed via the connecting plate 113 and the core adjusting assembly 112,
It will be in the ignition combustion state. The indication on the display plate 132 remains "ignition possible".

In the above state, the fuel tank 20
When the oil is consumed and the oil tank 20 becomes lighter, the tension of the display spring 133 exceeds the weight of the oil tank 20. Then, the display lever 131 is rotationally displaced counterclockwise in a side view (hereinafter, the description in a side view is omitted) with the bearing pin 14C as a fulcrum, and the display plate 132 displays “refueling”.

In the above state, when the fuel tank 20 is removed for refueling, the display lever 131 causes the projection 131E of the arm 131B to abut on the distal end 114F of the fire extinguishing lever 114 due to the pulling force of the display spring 133. Then, the fire extinguishing lever 114 is further rotated counterclockwise. As a result, the core 12 descends to enter a fire extinguishing state, and the display plate 132 displays "fire extinguishing".

Next, the operation when the wick 12 is lowered by the fire extinguishing lever 114 will be described. When the fire extinguishing lever 114 is pushed, the operating pin 115 attached to the operating plate 115
B is disengaged from the locking portion 114B of the fire extinguishing lever 114, and the operating plate 115 is returned to its original position by the pulling force of the descending spring 115F, thereby returning the operating plate 115, the fine adjustment plate 116 and the operation lever 111 to the original position, and performing fine adjustment. The elevating arm 117 rotates clockwise through the connecting plate 113 connected to the plate 116, and the core 12 descends.

Next, the operation of the earthquake-resistant automatic fire extinguishing unit 120 will be described. When the weight 122 tilts, the chain stopper 125 attached to the ball chain 124 raises the free end 114C of the fire extinguishing lever 114, and the operating pin 115B is disengaged from the locking portion 114B of the fire extinguishing lever 114. The operating plate 115 and the operating lever 111
Return by 5F, lead 12 descends. At this time, the chain 122 is pulled by the compression spring 126, and the weight 122 returns to its original inverted state.
