Flashlight improved structure

The invention provides a flashlight, in particular to a flashlight improved structure with fire protection and warning effect.

According to the flashlight, it is an indispensable lighting device in daily life. Especially in the absence of power or power generation equipment, the flashlight is one of the main tools that can be used for lighting, and the flashlight in the industry is quite diverse. The flashlights are used in different ways, and the form of the flashlights is different. Here, the flashlights used in diving, mine pits, rain disaster relief, or firefighters searching for trapped people at the fire site are used to explain Such a flashlight body must be able to withstand higher temperatures during the forming process, or have a trait of avoiding intrusion of outside water, and the use of the flashlight is particularly important in the attendance of firefighters.

When firefighters perform tasks in the fire, there is usually no power or power generation equipment in the fire. The light source in the fire is not enough. Therefore, firefighters except some basic fireproof equipment before entering the fire. In addition to wearing, the flashlight is more important. In particular, the flashlight used by firefighters is a waterproof and explosion-proof flashlight. The flashlight has a waterproof design due to the needs of its working environment, making the inside of the flashlight a sealed space. It can prevent water vapor from penetrating into the flashlight, and the explosion-proof flashlight is composed of LED light source, outer casing, rechargeable battery, switch, circuit board, etc. The explosion-proof mark and explosion-proof license number are cast on the obvious position on the outer casing. The rechargeable explosion-proof flashlight is for energy saving and environmental protection. Social design is also the way for manufacturers to adapt to consumer needs and reflect social responsibility. One way, the emergence of a more explosion-proof rechargeable flashlight solves the trouble of replacing the battery and also advantageously protects the environmental resources.

Moreover, when firefighters perform tasks in the fire, the temperature in the fire is unpredictable, and the number of equipment that the firefighters are equipped to detect the temperature of the temperature is limited, so it is impossible to know through the equipment. The degree of high temperature, therefore, even if firefighters are wearing fireproof clothing, the high temperature in the fire is also a threat to the safety of firefighters.

Therefore, how to solve the above problems and problems in the past, that is, the inventors of this case and the relevant manufacturers engaged in this industry are eager to study the direction of improvement.

Accordingly, in order to solve the above-mentioned shortcomings of the prior art, the main object of the present invention is to provide a flashlight improved structure for fire protection and having a warning effect.

In order to achieve the above object, the present invention provides a modified structure of a flashlight, comprising a casing and at least one circuit unit and a temperature sensing unit, wherein the casing has an accommodating space therein, and the casing is provided at one end position. a cover body, wherein the circuit unit is disposed in the cover body, and at least one light-emitting component and at least one alert component are disposed on one side of the circuit unit, and the temperature sensing unit is electrically connected to the circuit unit and generates a The temperature sensing signal is sent to the circuit unit, whereby the firefighter can use the light-emitting element to achieve the illumination effect when the flashlight structure is improved, and the temperature sensing unit of the flashlight-improved structure senses the ambient temperature, and The ambient temperature condition generates a temperature sensing signal to the circuit unit, and the warning component generates a warning to the firefighter to achieve the effect of informing the firefighter of the ambient temperature in advance.
