It is to make.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS. First, there is a writer main body 1, and the writer main body 1 has a substantially hollow cylindrical shape. Another hollow cylindrical portion 3 is provided on the side portion of the writer body 1 (on the right side in FIGS. 1, 2, and 3). The upper end of the writer body 1 is an upper end opening 5, and the upper end opening 5 is appropriately opened and closed by an opening / closing lid 7. A plurality of air holes 9 are formed in the upper part of the writer body 1.

  In the writer main body 1, as shown in FIG. 3, first, a main fuel chamber 11 is formed, and oil 13 as fuel is accommodated in the main fuel chamber 11. A lower end lid 15 is detachably attached to the lower end of the main fuel chamber 11. When the oil 13 as the fuel is injected into the main fuel chamber 11, the lower end cover 15 is removed.

  A partition wall body 17 is provided above the main fuel chamber 11. The partition wall body 17 is fixed to the inner peripheral wall of the writer body 1 and includes a hollow cylindrical portion 19 and a disc portion 21. A suction core cover 23 is installed so as to penetrate the disc portion 21 of the partition wall body 17. A suction core 25 is inserted and arranged in the suction core cover 23. The oil 13 in the main fuel chamber 11 is sucked upward through the suction core 25.

An end plug 27 is attached between the suction core cover 23 and the hollow cylindrical portion 19 of the partition wall body 17. A space surrounded by the disk portion 21, the hollow cylindrical portion 19, and the end plug 27 of the partition wall body 17 is a sub fuel chamber 29. A stopper member 31 is attached to the suction core cover 23 in the auxiliary fuel chamber 29. A coil spring 35 is installed between the stopper member 31 and the disk portion 21. The suction core 25 and the suction core cover 23 are always urged upward in FIG. 3 by the coil spring 35.
In the figure, the solid line shows the state when contracted, and the phantom line shows the state when extended.

As shown in FIG. 7, the suction core cover 23 is formed with three slits 41 at equal intervals in the circumferential direction. The slit 41 is formed at the upper end. Another slit 43 is formed. From the three slits 41, the oil sucked up through the suction core 25 is vaporized and injected. At this time, since the slits 41 are installed at three locations at equal intervals in the circumferential direction, fuel injection is performed in a well-balanced manner, and as a result, the flame balance is also good. The slit 43 is for communicating the auxiliary fuel chamber 29 and the main fuel chamber 11, thereby preventing a decrease in atmospheric pressure in the auxiliary fuel chamber 29 during use. It is.
As shown in FIG. 3, the slit 43 is formed to be relatively large in the upper part and small in the lower part.

  A crater cap 45 is attached to the open / close lid 7 already described, and a stopper 47 is attached. The crater cap 45 covers the upper ends of the suction core cover 23 and the suction core 25. That is, when the open / close lid 7 is closed, the suction core 25 and the suction core cover 23 are pushed downward by the crater cap 45 against the spring force of the coil spring 35 as shown in FIG. This completes the fire fighting. On the other hand, when the open / close lid 7 is opened, the suction core 25 and the suction core cover 23 protrude upward by the spring force of the coil spring 35. The stopper 47 is engaged with one of the air holes 9 already described, thereby restricting inadvertent opening of the opening / closing lid 7.

  Next, the configuration on the hollow cylindrical member 3 side described above will be described. First, the opening / closing lid 7 is attached so as to be rotatable about a hollow shaft member 51 as shown in FIG. That is, a pair of ear members 53, 53 are projected and arranged on the opening / closing lid 7 side. The hollow shaft member 51 is inserted and disposed between the pair of ear members 53. A coil spring 54 is installed on the outer peripheral side of the hollow shaft member 51, and a file 55 is installed on the outer peripheral side thereof. As shown in FIG. 6, a sleeve 52 is internally provided on the inner peripheral side of the hollow shaft member 51.

  Further, as shown in FIG. 6, a pair of sandwiching members 61, 61 are projected and arranged at the upper end of the hollow cylindrical member 3. The pair of ear members 53, 53 are inserted between the pair of clamping members 61, 61. The shaft members 63 and 63 are press-fitted and fixed in the sleeve 52 from both sides. Then, the opening / closing lid 7 rotates around the sleeve 52.

  Moreover, although it is the coil spring 54 already demonstrated, the one end is latched by the hollow shaft member 51 side. The other end of the coil spring 54 is a free end. When the opening / closing lid 7 is pivoted in the opening direction, the coil spring 54 expands its diameter against the spring force. Thereby, it is strongly pressed against the file 55 on the outer peripheral side. Therefore, the file 55 also rotates in the same direction as the opening / closing lid 7 rotates. On the other hand, when the opening / closing lid 7 rotates in the closing direction, the coil spring 54 is contracted by the spring force. Therefore, the pressure on the outer file 55 is released. Therefore, the file 55 does not reversely rotate with the turning operation of the opening / closing lid 7.

  In the hollow cylindrical member 3 below the file 55, the ignition stone 71 is accommodated and arranged. The ignition stone 71 is pressed from below by the ignition stone urging means 73. The ignition stone urging means 73 includes a shaft member 75, a pressing member 79 attached to the proximal end of the shaft member 75, an end member 76 attached to the distal end of the shaft member 75, and the outer periphery of the shaft member 75. And a holding coil spring 77 provided between the holding member 79 and the end member 76 on the side. The ignition stone 71 is pressed upward by the ignition stone urging means 73. The shaft member 75 is for restricting the extension amount of the holding coil spring 77 to a constant amount, so that even when the ignition stone 71 becomes small, it is caused by the spring force of the holding coil spring 77. It is configured not to jump out.

A file cover 91 is attached to the outer periphery of the upper end of the hollow cylindrical member 3 so as to be movable in the vertical direction. A female screw portion 93 is provided on the inner peripheral surface of the lower end portion of the file cover 91. On the other hand, a male screw portion 95 is provided on the outer peripheral surface of the upper end portion of the hollow cylindrical member 3. Then, when covering the file 55, the file cover 91 may be slid upward and the female screw portion 93 and the male screw portion 95 may be screwed together.
Incidentally, FIG. 1 shows a state covered with the file cover 91 and FIG. 2 shows a state where the file 55 is opened.

  Next, the structure for waterproofing is demonstrated. The oil writer according to the present embodiment has a completely waterproof structure. First, as shown in FIG. 3, a seal ring 101 is attached to the opening / closing lid 7 side. A seal ring 103 is also attached to the upper end of the hollow cylindrical member 3. Therefore, when the file cover 91 is pulled upward and screwed and fixed as shown in FIG. 1, the file 55 and the portion of the ignition stone 71 are completely water-tight. A seal member 104 is also attached between the pressing member 79 and the hollow cylindrical member 3.

  Next, a seal ring 105 is attached to the outer periphery of the upper end of the end plug 27. The seal ring 105 and the crater cap 45 provide a sealing function. Seal rings 107, 109, and 111 are installed between the writer body 1 and the lower end lid 15. By the seal ring 105 already described and these seal rings 107, 109, and 111, the writer body side is also completely waterproof.

The operation will be described based on the above configuration.
First, when not in use, the state is as shown in FIG. That is, the file cover 91 is pulled upward to cover the file 55 and to restrict the rotation operation of the opening / closing lid 7. In addition, since the female screw portion 93 provided on the file cover 91 is screwed into the male screw portion 95 provided on the hollow cylindrical portion 3 side, the file cover 91 will not accidentally drop downward. Therefore, for example, even if an infant or the like plays with their hands, it is possible to reliably prevent the occurrence of an accident that causes an accidental ignition.

  Next, the case where it uses is demonstrated. In this case, first, as shown in FIG. 2, the file cover 91 is lowered and the file 55 is opened. That is, the file cover 91 is rotated leftward in the state shown in FIG. As a result, the screwing of the female screw portion 93 provided on the file cover 91 and the male screw portion 95 provided on the hollow cylindrical portion 3 side is released. After that, the file cover 91 may be pulled downward. Thus, the opening / closing lid 7 can be rotated.

  When used, the entire oil writer is gripped with the right or left hand, and the opening / closing lid 7 is rotated with the thumb. Thereby, first, the upper ends of the suction core cover 23 and the suction core 25 are opened. At the same time, the file 55 rotates in the direction indicated by the arrow a in FIG. 9 and rubs the ignition stone 71. Thereby, a spark is generated, and the spark is ignited by igniting the fuel vaporized and injected from the upper end of the suction core 25.

Further, when the use is stopped, the opening / closing lid 7 may be rotated and closed with the thumb. As a result, the suction core cover 23 and the suction core 25 are pulled downward by the spring force of the coil spring 35. And it is extinguished completely by being covered with the crater cap.
At that time, the file 55 is not reversed in the reverse direction (the direction opposite to the direction indicated by the arrow a in FIG. 5) by the turning operation in the closing direction of the opening / closing lid. This is because the pressure contact of the coil spring 54 with the file 55 is released.

As described above, according to the present embodiment, the following effects can be obtained.
First, in this embodiment, the auxiliary fuel chamber 29 is provided above the main fuel chamber 11. For example, in the case of only the main fuel chamber 11 as in the prior art, the fuel pressure in the main fuel chamber 11 increases due to a change in the external temperature (for example, the temperature of the user's hand operating), and as a result, There was a problem that a lot of fuel was blown out at the time of ignition, and the flame temporarily increased. On the other hand, when the auxiliary fuel chamber 29 is provided as in the present embodiment, a pressure reducing effect is exhibited thereby, and a large amount of fuel is ejected at the initial stage of ignition, thereby preventing a large flame. It is something that can be done.
Next, in the case of this embodiment, the suction core 25 and the suction core cover 23 are configured to be pushed downward when not in use, and the crater cap 45 covers from above. It has become. Therefore, the fire is surely extinguished, and it is possible to reliably prevent the occurrence of a situation in which the fire is not surely extinguished even though the opening / closing lid 7 is closed as in the prior art.
Further, since the suction core cover 23 is provided with three slits 41 at equal intervals in the circumferential direction, the balance of fuel ejection is good and a well-balanced flame can be provided.
Further, the suction core cover 23 is formed with a slit 43, and the main fuel chamber 11 and the sub fuel chamber 29 are communicated with each other, so that the pressure in the sub fuel chamber 29 is reduced when the fuel is consumed, that is, during use. Can be suppressed, thereby enabling stable holding of the flame.
In addition, the file cover 91 is provided, and when not in use, the file cover 91 is raised to cover the file 55 and the opening of the open / close lid 7 is restricted. It is possible to prevent the occurrence of an accidental ignition.
In addition, the oil writer according to the present embodiment has a completely waterproof structure due to the seal members 101, 103, 104, 105, 107, 109, and 111. Absent.

The present invention is not limited to the one embodiment. The illustrated configuration is merely an example.

The present invention enables complete digestion at the time of extinguishing the fire, and raises the fuel pressure in the fuel chamber, thereby preventing the occurrence of a temporary large fire at the time of arrival and improving the stability and safety. Such a device is suitable for an oil writer.
