Abstract

PURPOSE:To enalbe a wick to be descended with a simple operation even in case that carbon is accumulated thereon by a method wherein there is arranged a releasing mechanism operated in conjunction with a wick descending lever when the wick descending lever is initially rotated and releasing an engagement between the engaging body and the engaging plate. CONSTITUTION:In case that carbon is accumulated and a wick 11 is not embedded into a clearance between a wick frame 10 and an air cylinder 9 under a resilient force of a wick descending spring 21, an operating body 55 at the back side of an outer case 1 is pushed down as shown by an arrow C, resulting in that the wick descending lever 52 is rotated to cause the abutting piece 52a to be abutted against a fixed frame 53, a vertical wick moving shaft 14 is rotated in a clockwise direction and thus the wick 11 can be descended. During this operation, a releasing plate 59 is rotated when the wick descending lever 52 is started to rotate, an engagement between an engaging shaft 37 and an engaging claw 33' is released and then the vertical wick moving shaft 14 is rotated. Thereby, even in the case that carbon is accumulated and the wick is not descended automatically when the combustion flame is extinguished, the wick can be descended with a simple operation.

Description

[Detailed description of the invention]

(What) Field of Application of the Invention The present invention relates to a wick up-and-down type combustion device in which the wick can be raised to the combustion position with a single touch by the downward movement of an operating button. (B) Prior art and problems The lamp wick is raised to the combustion position 1a with one touch by the downward operating pressure of the operation button, and the lamp wick raised to the combustion position is held by the locking plate of the vibration sensing device. (In the event of an emergency fire extinguishment such as an earthquake, the seismic device is activated, its locking plate releases the raised wick, and the elastic force of the wick lowering spring lowers the wick to the extinguishing position to extinguish the fire.) In addition, even during normal fire extinguishing, a lever dedicated to extinguishing is provided, and the locking plate of the vibration sensing device is operated by the lever dedicated to extinguishing,
The applicant has previously developed a wick up-and-down type combustion device that uses a wick lowering spring to lower the wick and extinguish the fire.
Application No. 56-134921 and Utility Application No. 13952
This is proposed in No. 9, etc. By the way, in the conventional device described above, only the elastic force of the wick lowering spring acts as a force for lowering the wick, so carbon accumulates and hardens at the upper end of the wick due to long-term use or the use of degraded kerosene. In this case, the elastic force of the wick lowering spring cannot lower the wick, resulting in various problems. One of these is the problem of not automatically extinguishing the fire even though the seismic device is activated during earthquakes and other tremors.The other problem is that the wick does not fall even though the fire extinguisher was supposed to be extinguished normally by operating the extinguishing lever. It burns forever in a small flame state, and C due to incomplete combustion pressure
The problem was the generation of a large amount of O. (c) Purpose of the Invention The present invention has been made in view of the above-mentioned problems. Carbon accumulates at the upper end of the lamp wick due to long-term use or the use of erroneously degraded kerosene, causing the wick to fail when extinguished. The main purpose is to allow the lamp wick to be lowered with a simple operation even when it does not lower automatically.The locking body and plate are designed to improve safety and maintain the lamp wick in the raised state when engaged. The object of the present invention is to provide a wick up-and-down type combustion device that can prevent damage to the wick. #) Structure of the Invention In order to achieve the above-mentioned object, the present invention rotates a centering lever by rotating a centering lever by lowering an operation button, and an arm plate interlocked with the centering vertical axis rotates a centering lever. The lamp wick is raised to the combustion position against the elasticity of the lowering spring, and the locking body that connects the lamp wick raised to the combustion position to the wick vertical axis engages with the locking plate of the vibration sensing device. The wick is held up and down by the locking plate, and when the locking plate is actuated, the locking body releases the engagement with the locking plate and the wick is suddenly lowered to the extinguishing position by the elastic force of the wick lowering spring. In the combustion device, a wick lowering lever for manually lowering the wick regardless of the elastic force of the wick lowering spring is provided on the wick up-and-down shaft, and at the beginning of rotation of the wick lowering lever, the wick lowering lever A release mechanism is provided in association with the center lowering lever, which operates in conjunction with the locking member and releases the engagement between the locking body and the stop plate.

An L-shaped release plate side is pivotally supported on the support plate 6 seconds, and a portion near the tip of the core lowering lever 5 slides into contact with the chevron-shaped protrusion ←0 provided at the upper end of the release plate 5ω. As a result, the release plate 69 is rotated, and at this time, υ of the lifting portion rolled at the lower position of the locking plate (A) moves the free end (1) side of the locking plate ((6) upward, The latch (G) is disengaged from the locking plate (37) prior to the rotation of the core vertical shaft (04). Although it is attached to the main shaft support board (A) with screws etc., it may be formed integrally with the shaft support board (22).The structure of the present invention is as described above, and the operation of the above structure will be explained next. (When igniting) First, push down the operation button (4) in the direction of arrow A.
The center raising lever (4'0) rotates, and the linked lever (451) rotates counterclockwise around the center vertical axis I.The rotation of this link lever (49) causes the roller (4'

direction and move the latch shaft movable body (27) guide rod (
C) rotates the rotating plate (C) counterclockwise at an angle of about 60 degrees, and the rotation of this rotating plate (C) causes the wick up and down shaft (14) and the arm plate (Ie to ) in the upward direction. Also, as the lamp wick 0υ rises, the wick lowering spring (21) compresses and lowers the lamp wick 0υ. Elastic force is accumulated, and the latch shaft is moved in place. When the fixed amount movement is completed, the locking claw part of the latch (2) locks with the locking shaft 071 of the locking plate (2), and the operation up to this point moves the lamp wick 01) from the extinguishing position to the combustion position. The ascension will be completed and the ascension state will be maintained. On the other hand, the wick raising lever (47) raises the lamp wick circle and at the same time the other end activates the ignition mechanism (4). Place the ignition heater (4ω) close to the tip of the lamp and ignite it by applying electricity. (Combustion adjustment) To adjust the raised lamp wick (11), turn the rotary knob (32 to

The lamp wick (11) can be raised and lowered by a vertical movement width of approximately 6 to 7 degrees. This core vertical axis (141
The slight rotation of the lamp wick a1) finely adjusts the height of the lamp wick a1) at the combustion position. (For normal fire extinguishing) Next, to explain the normal fire extinguishing button 61)
By pressing down and rotating the fire extinguishing lever (5) with the core vertical axis αa as the pivot point, the other end of the fire extinguishing lever 9 moves upward, and the locking plate (to) moves to the pivot pin (4). The latch (
The locking claw part (to) on the third floor is released from the lock and the °C latch shaft becomes movable. At this time, the lamp wick 0υ which is in the combustion position is suddenly lowered to the extinguishing position by the elastic force of the wick lowering spring eυ and is extinguished. As the lamp wick 01) descends to the extinguishing position, the wick vertical shaft (14) is rotated clockwise, and this rotation of the wick vertical shaft Q41 causes the latch shaft movable body ( 27) and latch (for emergency fire extinguishing) When vibrations such as an earthquake are transmitted to the exterior case (1), the weight of the seismic device 09 swings and the operating rod (40 is the disc 00
, and move the free end (to) of the locking plate (to) upward to release the engagement between the locking shaft (37) and the locking claw part (33) of the latch (c), and then The lamp wick αυ suddenly descends from the combustion position to the extinguishing position and extinguishes the fire. As mentioned above, whether the extinguishing lever (51m) is activated for normal extinguishing or the seismic device θ is activated for emergency extinguishing, the wick α1 is activated by the wick lowering spring Qυ for automatic extinguishing. It uses the elastic force stored in the fire to descend and extinguish the fire. By the way, when a combustion device is used for a long period of time, or when kerosene that has deteriorated due to long-term storage is used, carbon accumulates in the lamp wick I, which is the part that protrudes into the combustion tube (4), and this carbon is removed. kIK, as it hardens, the thickness of the wick 0υ increases at that part, and the elastic force of the wick lowering tin ring (2I) no longer fits within the space between the wick frame OI and the air cylinder (9), and in item (b). If a problem like the one mentioned above occurs, it will be a problem. In this case, the operating body 6 on the back of the outer case (1)
When one is pushed down in the direction of arrow C, the core lowering lever rotates and the contact piece (52a) contacts the fixed rod, and as the core lowering lever 1521 rotates, the core vertical axis a4 is rotated. By rotating the lamp wick clockwise, the wick 0υ can be lowered by applying force to the wick lowering lever (53). If you try to rotate the lead vertical axis a small in the clockwise direction while the lead vertical axis I is rotated, the latch shaft movable body (b) and the latch will move through the rotating plate (c) as the lead vertical axis I rotates. Since a force is applied to the shaft in the direction opposite to arrow B, there is a risk that the locking claw portion (2) and the locking shaft OD will be destroyed.Therefore, in the device of the present invention, the center lowering lever 6 is rotated. When the release plate 69 is started, the release plate 69 rotates, and its lifting portion moves the free end (product side) of the locking plate (G) upwards in advance of the rotation of the core vertical movement 04), and lifts the locking shaft. 67) and the locking claw portion 04, the core vertical shaft (+41) can be rotated by the core lowering lever 6. Therefore, the latch (3:l) and the locking plate There is no risk of damaging the 6'O.In addition, the wick has hardened and is difficult to fall down.
) may be replaced or air-baked to remove carbon. (f) Effects of the Invention Since the wick up-and-down type combustion device of the present invention is configured as described above, it is possible to solve the conventional problems and provide a highly safe device, and also to avoid accidental damage to the locking body or locking plate. It will not damage other parts.
