The invention discloses a voltage-sensitive resistor element with overheat protection, and relates to the technical field of basic electronic elements. The resistor element comprises a voltage-sensitive resistor chip, wherein a first connecting electrode and a second connecting electrode electrically connected with an electrode of the chip are arranged on a surface of the chip; the entirety of the chip and connection parts of the connecting electrodes and the chip are wrapped by an insulation coating; a protection device is arranged outside the insulation coating; a combined chip composed of the protection device, the voltage-sensitive resistor chip and the connecting electrodes is located in a housing; free ends of the connecting electrodes are located outside the housing. A short circuit shunt pathway is present in the resistor element; the presence of the short circuit shunt pathway releases surge current, which can protect a rear-end circuit from influence of surge when a voltage-sensitive resistor is degraded and failed; the short circuit current is easily detected by a front-end current fuse and other devices, so as to power off the complete machine equipment timely and avoid further damage.

The invention discloses a safe lighter belonging to a small fire-lighting device and mainly solving the problem that the traditional lighter is easy to cause fires after being touched by children due to no safety protection measures. The safe lighter comprises a lighter body; a protective cover is arranged at a fire-lighting start roller of the lighter body; and the protective cover is connected with the lighter body by using hinges. The safe lighter is provided with the protective cover, and fires and other accidents caused when the children open the lighter can be avoided due to the protection action of the protective cover.

The invention discloses a quenching oil bath chain motion state monitoring device and a quenching oil bath chain motion state monitoring method. The quenching oil bath chain motion state monitoring device comprises a main bracket and an adjusting plate arranged on the main bracket, a rotary shaft sleeve is arranged on the adjusting plate, a rotary shaft is arranged in the rotary shaft sleeve, a detection plate and a chain contact plate are respectively fixed at both ends of the rotary shaft, and one end of the chain contact plate is located at the center of one roller of a chain; a supporting rod is fixed on the main bracket, an adjusting sleeve is arranged on the supporting rod, a detection bracket is welded on the adjusting sleeve, and a proximity switch is arranged on the detection bracket. The invention has the advantage that the quenching oil bath chain motion state monitoring device can effectively detect the occurrence of various abnormal running states such as the breakage of the lifting chain or the abnormality of the chain under a driving shaft in time, and can cut off the main power supply of peripheral equipment and related equipment in time to prevent processed hot materials from continuously entering an oil bath and prevent the occurrence of accidents such as a fire.

The invention discloses a high-carbon preservative bamboo carbonizing method, which comprises the steps of 1) removing tabasheer from a fresh bamboo to obtain a bamboo splint, and drying the bamboo splint; 2) paving the bamboo splint flat on a disposing rack, measuring the paving thickness h of the bamboo splint, and setting a carbonizing standard according to the paving thickness h; 3) heating by phases according to the set carbonizing standard and keeping the temperature of each phase until all organic matter clearance of the bamboo splint inside a carbonization kiln reaches a maximum value while satisfying a flexibility requirement; 4) after carbonization, cooling the carbonization kiln by atomization cooling to obtain the high-carbon preservative bamboo. According to the invention, the preservative performance of the bamboo can be greatly improved; bamboo stacked in different heights can be carbonized uniformly. In this way, the color of the carbonized bamboo is uniform; color difference is avoided; advantages like short production period, simple operation, safety and environmental protection are provided.

The invention designs a safety burning torch with a vertical movement type push button. By using the safety burning torch, the technical problems that a push button of a conventional safety burning torch is in inwards pressed-in mode and the mis-operation is easily performed are solved. The safety burning torch comprises a torch body, an oil groove, a prying plate and piezoelectricity; the oil groove is arranged in the torch body; the prying plate is mounted on the oil groove; a pressing handle capable of vertically sliding is mounted on the torch body; and a piezoelectric working part which is downwards convex, and furthermore, is arranged in a way of being staggered with the upper end part of the piezoelectricity in an ordinary state is formed on the inner wall of the pressing handle. The safety burning torch is characterized in that the pressing handle is matched with a sliding block enabling the pressing handle to transversely move; a transverse part is formed at the end of the sliding block, which approaches the push button; the push button which can vertically shift is arranged at the outer side of the transverse part; furthermore, the outer half part of the push button is positioned outside the torch body; and an oblique plane for pushing the sliding block to move is arranged at the lower end of the inner half part of the push button. According to the safety burning torch, the pressed button is changed into the vertical movement type button; accidents such as a fire disaster and the like, caused by the mis-operation of a child and a retardate, can be prevented; and the safety performance of the burning torch is further promoted.
