Problems solved by technology

The most fatal is the heating of the gas cylinder by the external heat source. At this time, the overvoltage protection device of the cassette furnace itself will not work
The reason is that the overpressure protection device only cuts off the gas path when the pressure is too high to prevent the cassette furnace from continuing to burn.
However, when the overvoltage protection device is activated, the user does not know it, and most people will continue to eat without realizing the potential danger. The danger is that the ambient temperature near the gas cylinder is still rising, and the safety hazard has not been eliminated.
The increase in ambient temperature will further increase the pressure of the gas cylinder. If measures are not taken in time, the gas cylinder will explode.
Therefore, the safety device of the existing cassette furnace still cannot eliminate the potential safety hazard caused by the increase of ambient temperature near the gas cylinder

Embodiment 1

[0025] A high temperature alarm device, its structure principle diagram is as follows figure 1 Shown: it includes a loop composed of a power supply 11, a sudden jump normally open thermostat 12 and an alarm device 13. Specific, such as figure 2 Shown: it includes a boxed housing 10, the housing 10 is provided with a sudden jump type normally open thermostat 12, a battery as a power source 11 and an alarm device 13 (buzzer), sudden jump type normally open temperature The controller 12, the battery and the buzzer are all potted in the housing 10 with an insulating material 14. The insulating resin material can be epoxy resin (or silicone potting). The bottom of the casing 10 has a through hole, and the snap-type normally open thermostat 12 is embedded in the through hole and its sensing surface protrudes from the bottom of the casing 10. This structure is relatively small and thin, and does not take up more installation space.

Abstract

The invention discloses a high-temperature alarming device and a safe type gas device. The high-temperature alarming device is characterized by comprising a loop composed of a power supply, a snap action type normally-opening thermostat and an alarming part (for example, a buzzer). According to the safe type gas device, a gas bottle is used as a source of gas, and the device is provided with gas source containing space for containing the gas bottle; the high-temperature alarming device is arranged in the gas source containing space (the high-temperature alarming device also can be arranged in the position of a metal plate close to the gas bottle); and a temperature sensing part of the snap action type normally-opening thermostat of the high-temperature alarming device is pasted to the metal plate constituting the gas source containing space. It can be effectively controlled that when the gas device is used, at the time of occurring of safety hidden danger (alarming also can be conducted on the danger generated at the time of overvoltage insurance failure) caused by heating of an external heat source to the gas bottle, the high-temperature alarming device timely reminds a user to conduct corresponding treatment, so that the purpose of safe using is achieved.

Description

Technical field [0001] The invention relates to a safety alarm technology for gas equipment, in particular to a high temperature alarm device and a safe gas device. Background technique [0002] The cassette stove refers to non-fixed household kitchen utensils, hotel supplies, and outdoor leisure products that use butane gas as the main fuel gas, liquid gas and other gases that can also be used for direct fire heating. The cassette stove is also called a portable butane gas stove or a portable barbecue stove. According to the shape, it is mainly divided into single-eye, double-eye, mini-type and ultra-thin type, and single-use and dual-use cassette furnaces. [0003] When the cassette furnace is working, butane gas enters the regulator from the butane cylinder, and enters the furnace head through the adjustment of the regulator (the user adjusts through the knob), while mixing a part of the air (this part of air is called primary Air), these mixed gases are ejected from the fire ...
