Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a wick retention device for a liquid fuel combustor.

In a conventional liquid fuel combustor, such as an upper-and-lower wick kerosene stove, the wick 1 fits into a wick guiding annular path 4 formed by an inner cylinder 2 and an outer cylinder 3, as shown in FIGS. 1 and 2. A pinion (not shown) is engaged with a rack 6 provided on a core presser 5 attached to the outside of the core 1, and the core 1 is slid up and down by a knob that interlocks with the pinion. 7 is a fuel storage tank, 8 is a locking nut that joins the outer cylinder 3 to the tank 7, and 9 is a packing.

When replacing the core 1, first move back the pinion that engages with the rack 6, and then tighten the retaining nut 8 of the outer cylinder 3.
is removed, the outer cylinder 3 is removed, the lead 1 is pulled out from the inner cylinder 2 together with the lead holder 5, and then the lead 1 is removed from the lead holder 5 and replaced with a new lead. This operation is very complicated for general consumers. In addition, the wick up/down mechanism for adjusting the combustion range is combined with an earthquake-resistant fire extinguishing mechanism for safety, and depending on how the adjustment is made after replacing the wick, the safety earthquake-resistant fire extinguishing mechanism may also be affected. , there was a risk that the safety of the stove would be compromised.

In addition, some kerosene stoves with upper and lower wicks have a structure in which the wick is divided into one for combustion and one for sucking up oil, which can be moved in and out. The drawback was that there were parts of the wick that did not absorb enough oil.

The purpose of the present invention is to eliminate the above-mentioned drawbacks, to provide a liquid fuel combustor that allows for easy wick replacement independently of the wick vertical adjustment mechanism, safety earthquake-resistant fire extinguishing mechanism, etc., and that also has good liquid fuel suction. This invention provides a wick holding device.

In order to achieve the above object, the present invention divides the core into an upper core and a lower core, which are fitted into an inner cylinder, and the lower end of the upper core and the upper end of the lower core are made to protrude outward. The inner surfaces of the core and lower core are brought into contact with each other, and the upper core holder attached to the outside of the upper core is removably fitted to the lower core holder attached to the outside of the lower core to separate and separate the upper and lower cores. It is characterized by being flexible.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Note that in the conventional example shown in FIGS. 1 and 2 and the embodiments shown in FIGS.

As shown in FIG. 3, the core 1 is divided into an upper core 1a and a lower core 1b, which are fitted into an inner cylinder 2.
A molded ring 10, which is also fitted into the inner cylinder 2, is inserted between the upper core 1a and the lower core 1b. The lower end of the upper core 1a and the upper end of the lower core 1b extend outward, and their inner surfaces are in contact with each other. As shown in FIG. 5, the molded ring 10 has a substantially triangular cross section and is made up of one piece or two pieces divided into upper and lower parts. 5a is an upper core holder attached to the outside of the upper core 1a, and 5b is a lower core holder attached to the outside of the lower core 1b, and both are removably fitted to form the upper core 1a and the lower core 1b. It is constructed so that it can be freely approached and separated via a ring.

FIGS. 6 and 7 show the upper mandrel 5a, and a claw 11 for engaging with the core is provided protruding from the inner periphery of the main body of the upper mandrel 5a. Further, a flange 12 is provided at the bottom of the main body, and the flange 12 has a plurality of protrusions 1.
3 will be provided.

FIGS. 8 and 9 show the lower tail presser 5b, and the inner periphery of the main body of the lower tail presser 5b is provided with protruding claws 14 for engaging with the core like the upper tail presser 5a, and the upper edge 15 of the main body A guide groove 16 is provided. The guide groove 1
By inserting the protrusion 13 of the upper tail presser 5a into the upper tail presser 6 and rotating it, the upper tail presser 5a is fitted into the lower tail presser 5b. A rack 6 is provided on the outer peripheral surface of the main body of the lower core presser 5b, and engages with a pinion (not shown), and the core is slid up and down by a knob that interlocks with the pinion.

When replacing the core, remove the retaining nut 8 of the outer cylinder 3, remove the outer cylinder 3 from the fuel storage tank 7, rotate the upper core presser 5a in the opposite direction, and replace the lower core presser 5.
b, and remove the upper core 1a from the upper core presser 5a.
At the same time, the core is removed from the inner cylinder 2 and replaced with a new core.
The lower part of the refill is spread out in advance so as to follow the shape of the molded ring 10, and the refill is fastened to the claws 11 on the inner circumference of the upper tail presser 5a, and then the protrusions 13 of the upper tail presser 5a are held together. Lower tail presser 5b
Insert it into the guide groove 16 provided on the upper edge and rotate it to engage the upper tail presser 5a with the lower tail presser 5b,
The upper core 1a is closely integrated with the lower core 1b.

Note that the upper and lower tail pressers 5a and 5b are
They may be removably engaged by a stopper 18 as shown in FIGS. 0 and 11. That is, flanges are provided at the lower part of the upper tail presser 5a and at the upper part of the lower tail presser 5b, and both flanges are fixed together with a stopper 18.
has a groove 19 having a substantially U-shaped cross section into which both flanges overlapped, and is rotatably attached to the flange of the lower core presser 5b. 20 is a knob used when removing the stopper 18.

As described above, the present invention has a structure in which the core is divided into upper and lower parts and can be attached and detached, so that only the upper core is required to replace the core, and this can be done extremely easily. In addition, since the wick can be replaced completely independently of the wick's vertical adjustment mechanism and the safety seismic fire extinguishing mechanism, there is no need for adjustment after replacing the wick as in the past, and there is no effect on the safety seismic fire extinguishing mechanism. Therefore, there is no risk that the safety of use of the combustor will be compromised.

In addition, the lower core, which does not require replacement, can be left in place and used semi-permanently, resulting in a resource-saving effect.

Furthermore, the lower end of the upper core and the upper end of the lower core are each extended outward and their inner surfaces are in contact with each other, so the end surfaces of the cores do not just contact each other, but come into close contact over a wide area. Therefore, the fuel is sucked up evenly, and a sufficient amount of fuel can be sucked up just like the conventional one-piece wick.
