The specific embodiment is as follows:
referring to fig. 1 to 4, the automatic shut-off device of the fuel heater comprises a fuel tank 1, a wick device 2, a flameout switch 3 and a decorative cover 4.
An adjusting shaft 22 for driving the lamp wick 21 to lift in the lamp wick device 2 extends out of the oil tank, and a reset torsion spring 23, a ratchet wheel 24 and a knob 25 are sequentially arranged on the adjusting shaft 22. The lamp wick 21 can be driven to rise and fall by rotating the knob 25, the flame size can be adjusted by rising, and the flame can be extinguished by falling.
One end of the flameout switch 3 is fixed with a stopping shaft 31, the other end is an operating rod 32, the flameout switch 3 is positioned on the oil tank 1 through a pin shaft 33, a small torsion spring 34 is sleeved on the pin shaft 33, and the small torsion spring 34 always keeps the stopping shaft 31 to be buckled on the ratchet wheel 24, namely to be buckled on the ratchet teeth, and the flameout switch has a static single-body stopping function. More specifically, the flameout switch 3 is an L-shaped sheet metal part bent at right angles, and has a short end and a long end, the pin shaft 31 is arranged at the bending position, the short end is fixed with the rotation stopping shaft 31, the long end is used as the operating rod 32, the operating rod 32 can actually form a rocker action, and the locking action on the ratchet wheel 24 can be released with a small force. Thus, by means of the cooperation of the operating lever 32 with the heavy ball 5, the vibration and dumping automatic closing actions are achieved. In a general design, the operating rod 32 is horizontal, and the handle part is exposed out of the decorative cover 4 for manual power to touch upwards to extinguish. The decorative cover 4 is installed outside the oil tank 1, covering the ratchet 24 and the flameout switch 3 therein.
The end of the operating rod 32 of the flameout switch is hung with a heavy ball 5, and a movement gap of not more than 5mm exists between the heavy ball 5 and the surface of the operating rod 32. More specifically, the center of the heavy ball 5 is provided with a through hole 51, a rope or a bead chain 6 with a limit node 61 at one end passes through the through hole 51 and is tied on the operating rod 32, and a movement gap exists between the heavy ball 5 and the rope or the bead chain, so that the heavy ball can move relatively. The heavy ball 5 and the operating rod 32 generate asynchronous action during vibration, and the drag force or impact force generated by the heavy ball 5 is increased by matching with the seesaw effect formed by the longer operating rod 32, so that the flameout switch 3 is driven to act to release the constraint on the ratchet wheel 24.
The heavy ball is tied on the operating rod, and the heavy ball 5 can be in the following two states, but in any state, the heavy ball 5 still has the trend of keeping the stopping shaft 31 buckled on the ratchet wheel 24, and the heavy ball is kept in the stable ignition state.
1. The heavy ball 5 is tied on the operating rod 32, namely tied on the upper surface of the operating rod 32, and is restrained on the upper surface of the operating rod 32 by a rope or a bead chain 6, so as to avoid rolling out of the operating rod area. I.e. to the upper surface of the lever 32, ensuring the position of the point of involvement or impact. As shown in fig. 2, 3 and 4, the two ends of the bead chain 6 are both provided with limit nodes 61 by using buckles, and the bead chain is assembled by clamping with tools, so that the bead chain is also applicable to a rope structure.
2. The heavy ball 5 is hung on the operating rod 32, namely, is hung on the lower surface of the operating rod 32, and is restrained on the lower surface of the operating rod 32 by a rope or a bead chain 6, so that the heavy ball is prevented from drifting out of a projection area of the operating rod 32. When vibration or dumping occurs, the bouncing heavy ball 5 impacts the lower surface of the operating rod 32 to unlock the ratchet wheel 24, and the reset torsion spring 23 automatically closes the lamp core 21.
Furthermore, a fixing piece 11 is welded below the oil tank 1 corresponding to the adjusting shaft 22, the flameout switch 3 is rotatably positioned on a switching piece 35 through a pin shaft 33, the decorative cover 4 is also locked on the switching piece 35, and then the decorative cover is locked on the fixing piece 11 through the switching piece 35, so that an assembly structure with the oil tank 1 is formed.
