Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention belongs to the field of household stoves generally applied, and is used as a petroleum stove with a disaster prevention measure at the time of lubrication in a lamp type oil stove. .

(Prior Art) Conventionally used lamp type oil stoves are provided without any precautions for disaster prevention between the raising and lowering of the wick and the opening and closing of the lubrication tank and the lubrication port. As a result, it is possible to open and close the lubrication port freely even during combustion, resulting in serious accidents or obstruction due to unexpected flames that could be introduced into the lubrication tank during combustion easily.

(Problems to be Solved by the Invention) In view of the above circumstances, the present invention provides a petroleum stove that eliminates the drawbacks of the prior art by making sure that the oil is extinguished during combustion so that oil cannot be injected during combustion. It is the one we are trying to provide.

(Means for Solving the Problems) The oil stove according to the first aspect of the present invention is an oil stove having a fixed type oil tank, wherein a cap that engages with an oil inlet of the oil tank hangs down the shaft portion. A small-diameter shaft is formed in a part of the shaft, and at the vertical position of the small-diameter shaft in the engaging position of the cap, a horizontally swingable link is pivotally supported in the oil tank, From the direction in which one end of the link is detachably engaged with the small-diameter shaft with a predetermined pressing force, and the other end of the link is detached from the small-diameter shaft,
An integral hook is attached to the outer periphery of the horizontally rotating wick tube so that it can freely come in and out, while the other end of the lever pressed by the lower end of the shaft of the cap extends in the opposite direction outside the lubrication tank via the horizontal shaft. It has a disaster prevention mechanism which is detachably attached to a stopper integrated with a rotary shaft for horizontally rotating the wick tube while being taken out.

A petroleum stove according to a second aspect of the invention is an oil stove in which an oil tank can be detached and attached, in which vertical movement of a vertically moving wick tube is converted into horizontal movement of a slider slidably guided by a horizontal axis, and the horizontal movement of the slider. In conjunction with the movement, the horizontal shaft is guided forward and backward to the upper surface of the protruding portion at the lower end of the oil tank, while the other end of the lever pressed by the bottom surface of the oil tank moves up and down the wick tube via the horizontal shaft. It has a disaster prevention mechanism which is detachably engaged with a stopper integrated with a rotating shaft with a predetermined pressing force.

(Operation) The small diameter shaft in the shaft portion of the cap of the first aspect of the invention locks one end of a link pivotally supported by the oil tank at the wick rising end (during combustion) to prevent the cap from coming off. The hook integrated with the wick barrel disengages one end of the link from the small diameter shaft at the wick lowering end (when extinguishing the fire) to put the cap in the detached state, and the lower end of the shaft portion of the cap is a lever supported by a horizontal shaft. Pressing one end, the other end of the lever extended in the opposite direction outside the lubrication tank is disengaged from the stopper integral with the rotating shaft of the wick tube to make the rotating shaft rotatable, and at one end of the lever. When the pressure is released (when the cap is detached in the fire extinguishing state), the other end of the lever is engaged with the stopper with a predetermined pressing force to restrain the rotation shaft from rotating.

The horizontal axis of the second invention advances to the upper surface of the projecting portion at the lower end of the oil tank at the rising end of the wick (when burning) to prevent the oil tank from coming off, and at the falling end of the wick (when extinguishing fire) Is retracted from the upper surface of the protruding part to put the lubrication tank in a disengaged state, and the other end of the lever pressed by the bottom surface of the lubrication tank is disengaged from the stopper integrated with the rotating shaft that raises and lowers the wick tube to rotate the rotating shaft. The other end of the lever, which is in a movable state, when the pressure is released by the bottom surface (when the lubrication tank is disengaged) is engaged with a stopper with a predetermined pressing force to non-rotatably restrain the rotating shaft.

(Embodiment) Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In a petroleum stove of a fixed lubricating tank type, as shown in FIG. 1 and FIG. The hook 3 is integrated with the wick tube 2 for rotating and raising and lowering the wick, while the link 6 is joined to the inner surface of the upper part of the protective cover 5 of the lubrication tank 4 with the pin 8 at a predetermined position so that the link 6 can be horizontally swung. A notch 7 is provided at one end of the link 6, one end of a spring 9 is locked to the link 6 between the pin 8 and the notch 7, and the other end of the spring 9 is fixed to the inner surface of the protective cover 5. . Rotating shaft 10 integrated with knob 1 has a stopper
A front lever 13 is integrally provided on the front side of the cover 5 and a rear lever 14 is integrally provided on the inner side of the horizontal shaft 12 rotatably provided on the front side of the protective cover 5 in the front portion of the protective cover 5. The tip of the lever 13 is disposed at a position where it engages with the stopper 11, and between the tip and the horizontal shaft 12, the other end of a spring 16 having one end fixed to the flange 15 of the oil tank 4 is locked, and the rear part The other end of the torsion spring 17 whose one end is locked to the bearing is locked to the lever 14, and the tip of the lever 14 is arranged so as to cross the oil filling port 18.

According to the above configuration, when the knob 1 is rotated counterclockwise, the wick tube 2 is rotated clockwise, and as a result, the wick 19 is lowered to the lowest position.
At this time, the hook 3 integrated with the wick 2 rotates the rear end of the link 6 counterclockwise. Therefore, the notch 7 of the link 6 that is locked to the small diameter shaft 21 of the shaft portion that hangs on the cap 20 that seals the oil filling port is to be cooled from the small diameter shaft 21. The cap 20 can be removed from the oil filling port 18 in a safe state, and at the same time, when the oil filling port 18 is opened, the front lever 13 is rotated counterclockwise about the horizontal shaft 12 by the spring 16 and the torsion spring 17 and the tip thereof is opened. The stopper 11
It is to be locked to. Therefore, not only during lubrication, but because the knob 1 cannot be rotated when the lubrication port 18 is forgotten to be tightened, the wick 19 cannot be raised to the burning position, and ignition in a dangerous state is not possible. It will not be possible. Therefore, be sure to fill the oil inlet to ignite.
Safety is ensured on condition that 18 is sealed with a cap 20. That is, when the lower end of the shaft of the cap 20 presses the rear lever 14, the tip of the front lever 13 is separated from the stopper 11 and the rotary shaft 10 is free to rotate, so that the wick 19 can be raised to the combustion position. Is.

Next, a description will be given of an embodiment of an oil stove with a removable oil tank. As shown in FIG. 5, one end of a wire 22 is locked to a wick tube 2'which is vertically moved by turning a knob 1 '. The other end of 22 is a roller that is properly bearing
It is guided by 23 and is locked by the slider 24. The slider 24 is slidably engaged with a locking rod 26, which is a horizontal shaft guided by left and right bearings 25, 25 'standing upright and left at predetermined intervals. Stoppers 27 and 27 'are fixed at the tip of the locking rod 26 protruding from the left bearing 25 and the left portion of the slider 24, respectively, and a spring 28 is mounted between the left bearing 25 and the stopper 27', and the right portion is mounted. Bearing 2
The other end of a spring 29, one end of which is locked to the slider 24, is locked to 5 '. On the other hand, as shown in FIGS. 3 and 4, a rotary shaft 10 'for vertically moving the wick 2'is provided with a stopper 11', and a bearing 31 standing on a flange 30 of the main body is provided with a horizontal shaft 12 '. The lever 32, which is rotatable around the center of the lever 32, is locked so that the tip of the lever 32 is locked to the stopper 11 ', and one end of the flange 30 is provided between the tip and the horizontal shaft 12'. The other end of the fixed spring 33 is locked, and the lever 32
The rear end 37 is arranged at a position pressed against the bottom surface of the oil supply tank 34. Therefore, when the knob 1'is rotated counterclockwise to lower the wick tube 2'and sink the wick 19 'to the lowermost position, one end of the wire 22 is also lowered, and at the same time, the slider 24 moves above the locking rod 26. It will slide to the left, but at this time, the stopper 27 'integral with the locking rod will be pushed in, and as a result, the locking rod 26 will also be moved to the left, and its right end will engage until now. Since it is separated from the protruding portion 35 of the bottom plate of the lubrication tank 34, the lubrication tank 34 can be lubricated to the lubrication tank 34 in a safe state where the lubrication tank 34 is pulled out from the main body of the oil stove and extinguished. After the oil tank 34 is pulled out from the main body of the oil stove, the oil inlet 36 on the main body side is in an open state.
Rotates left about the horizontal axis 12 ', and its tip is stopped
Since the knob 1'is locked by 11 ', the knob 1'cannot be rotated in the dangerous state as described above, so that the lamp core is not ignited. In order to ignite, the lubrication tank 34 must be set in position and safety must first be maintained. That is, the bottom surface of the lubrication tank 34 is located at the rear end 37 of the lever 32.
Is pressed, the tip of the lever 32 is disengaged from the stopper 11 ', and the wick 19' can be raised. Therefore, when the knob 1'is rotated clockwise to raise the wick tube 2'and the wick 19 'is placed in the combustion position, the slider 24 is pulled to the right by the spring 29, and at the same time, the left bearing 25 is locked at one end. 28 presses the stopper 27 ′ to the right, and naturally the locking rod 26 also moves to the right, and its right end is the protruding portion of the oil tank 34.
Since it interferes with the upper surface of 35, the lubricating tank 34 cannot be pulled out in the combustion state, and the relationship between lubrication and ignition is safely interlocked as in the oil tank fixed oil stove described above. It is possible to completely prevent accidental accidental fire.

(Effect of the invention) As described above, in the present invention, in the lamp type oil stove, most of the disaster prevention mechanism depending on the relationship between the position of the wick and the lubrication state is housed inside the oil stove, and a smart appearance is exhibited. Regardless of the user's will, it is possible to lubricate and ignite only in a safe state, and it is possible to completely prevent misfire, which is mainly due to carelessness during lubrication.
