Description

[Detailed Description of the Invention] The present application relates to the invention of an oil-burning appliance with an upper and lower wick, which eliminates the inclination of the combustion wick, allows for smooth lifting and lowering, and facilitates disassembly and assembly.

Examples will be described below with reference to the drawings.

1 is a tank main body, with an inner core cylinder 2 erected, an annular opening between it and an outer core cylinder 3, and a combustion wick 5 held by a wick holding cylinder 4 interposed in the annular opening so as to be movable up and down. I'm letting you do it.

A rack plate 7 having a rack 6 carved in a substantially vertical direction and provided with a stepped protrusion is fixed to the lead holding cylinder 4.

Reference numeral 8 denotes a core adjustment shaft having a pinion 9 at its tip that engages with the rack 6, into which a collar 11 having a locking groove 10 is loosely fitted.

12 is provided with bent portions on both sides for superimposing the rack plate 7 so as to be slidable up and down, is provided with an inverted U-shaped cut 13 to be inserted into the locking groove 10 of the collar 11, and has a cover for the outer core cylinder 3. It is a guide locking plate equipped with a knob protrusion 14 that is pressed and fixed at times.

In the figure, 15 is a support tube through which the core adjustment shaft 8 is inserted, and 16 is an angle that supports the support tube 15.

Since the present invention is constructed as described above, when assembling, first insert the wick holding cylinder 4 with the combustion wick 5 attached into the wick inner cylinder 2 of the tank main body 1, so that the pinion 9 engages with the rack 6 of the rack plate 7. Insert the core adjustment shaft 8 into the support tube 15 and attach the guide locking plate 1.
The inner edge of the notch 13 is fitted into the locking groove 10 of the collar 11, and then covered with the core outer cylinder 3.

At this time, the guide locking plate 12 is attached to the rack plate 7 so as to overlap with each other, so that when the core adjustment shaft 8 is rotated to raise and lower the core holding tube 7, the core holding tube 7 is moved like a conventional one. The rack plate 7 and the guide locking plate 12 can be smoothly slid and raised and lowered without going up and down while tilting, and the core adjustment shaft 8 can also be prevented from coming off.

In other words, in the conventional type, the raising and lowering was not smooth, so the wick holding cylinder had to be rotated to raise and lower, and a guide ring was attached to the inner circumferential surface of the combustion wick to improve slippage, resulting in high costs. However, in this case, the guide locking plate 12 provides a smooth guiding action when the rack plate 7 is raised and lowered in the vertical direction, so the gap between the core inner cylinder 2 and the core stopper pawl 17 of the core holding cylinder 4 is smaller than in the conventional case. can be made smaller, further preventing the combustion wick from tilting.

The present invention also has the advantage that since the guide and locking plate 12 is provided with the knob protrusion 14, it can be easily attached and detached.

Furthermore, if a retaining protrusion 18 is provided at a suitable position on the inner edge of the notch 13 of the guide locking plate 12, it is possible to prevent the locking plate 12 from also rising when the rack plate 7 rises.

Alternatively, a guide protrusion 19 may be provided protrudingly on the rack plate 7 as a guide means when the lead holding cylinder 4 is raised and lowered, and a guide hole 20 may be provided on the knob protrusion 14 of the guide locking plate 12 for engagement. .

As described above, the present invention is easy to attach and detach, and has many practical effects, such as being able to use one component as a lock to prevent the core adjustment shaft from coming off and as a guide for raising and lowering the core holding cylinder.

Claims (2)

[Scope of utility model registration request] (1) A wick holding cylinder equipped with a rack that holds the combustion wick 4 and raises and lowers it vertically is attached to the wick guide cylinder of the tank so that it can be raised and lowered,
In an oil combustion appliance in which a combustion wick 4 can be raised and lowered by rotating a wick adjustment shaft having a pinion at the tip that engages with the rack plate, a rack plate having a stepped protrusion and the rack plate are superimposed so that the rack plate can be slid up and down. It has bent parts on both sides to hold the core, has a notch that is removably loosely fitted into the locking groove of the collar that is loosely fitted to the core adjustment shaft, and has a knob protrusion that is pressed and fixed when the core outer cylinder is covered. When the guide and locking plate is installed, the rack plate is fixed in the tank and can be moved up and down by the rotation of the core adjustment by the guide and locking piece. oil-burning appliances. (2) The oil-burning appliance according to claim 1 of the Utility Model registration, wherein a guide protrusion is provided on the rack plate, and a vertical guide strip is provided in which the guide protrusion is loosely fitted to the knob protrusion of the guide and locking plate.
