Fig. 1 shows a schematic view of the overall structure of the fire-fighting flashlight in an embodiment of the present invention. For the purpose of illustration, the drawings show only the structures associated with embodiments of the invention.

Referring to fig. 1, an embodiment of the present invention provides a fire flashlight 100, which includes a housing 10, a heat conductive layer 20, and a heat insulation layer 30. The housing 10 has a receiving space 11 for receiving a battery 14. The heat conductive layer 20 is attached to the inner wall of the receiving chamber 11. The heat insulation layer 30 is circumferentially arranged on the outer side of the shell 10 along the shell 10, and the position of the heat insulation layer 30 at least partially corresponds to the position of the accommodating cavity 11.

It should be noted that the housing 10 forms the main body of the fire flashlight 100. For convenience of use, the housing 10 may be configured as a cylinder, and of course, the housing 10 may be configured as other structures according to practical situations.

The accommodating cavity 11 is opened along the axial direction of the housing 10 and is configured as a hollow cylinder so as to be used for placing the lighting power supply. The heat conduction layer 20 is coated on the inner wall of the accommodating cavity 11, and when the fire flashlight 100 is used, the lighting power supply in the accommodating cavity 11 continuously generates heat, so that the overall temperature in the accommodating cavity 11 sharply rises. The temperature in the accommodating cavity 11 can be dissipated through the heat conducting layer 20, so that the situation that the temperature in the accommodating cavity 11 is too high to damage all components of the fire-fighting flashlight 100 is avoided, and the heat dissipating performance and the safety performance of the fire-fighting flashlight 100 are improved.

Further, since the fire flashlight 100 is usually held by hand for illumination when in use, the receiving cavity 11 is used for receiving an illumination power source and is usually disposed at the rear half of the housing 10, i.e. at the holding portion 13. When the heat radiation performance of the housing chamber 11 is improved, the heat generated in the housing chamber 11 is rapidly diffused, easily causing the temperature of the hand-held portion 13 to increase. In this case, when the user holds the fire flashlight 100, the user is likely to feel discomfort because the user needs to receive the high temperature from the hand-held portion 13.

Based on this, the thermal-insulating layer 30 is arranged around the outer side of the shell 10 along the circumferential direction, so that heat transfer can be better isolated, and the use comfort of the fire-fighting flashlight 100 is improved.

In some embodiments, the thermally conductive layer 20 is a thermally conductive silicone layer. Because the heat-conducting silicone grease has high heat conductivity, excellent heat conductivity and good electrical insulation, the heat dissipation efficiency can be improved, and the fire-fighting flashlight 100 is prevented from being damaged due to overhigh temperature in the shell 10.

In some embodiments, the insulation layer 30 continuously surrounds and wraps the casing 10 along the circumference of the casing 10. When a user holds the fire flashlight 100, the heat insulation layer 30 circumferentially covering the housing 10 can provide better heat insulation to prevent the user from feeling uncomfortable while holding the fire flashlight 100.

It is understood that in some other embodiments, the insulation layer 30 may be wound at intervals along the axial direction of the housing 10, and in this case, since the insulation layer 30 is disposed to protrude from the housing 10, when the fire flashlight 100 is held by hand, the skin only contacts with the protruding insulation layer 30, but not with the housing 10, so that the insulation effect can be achieved as well.

In some embodiments, the thermal insulation layer 30 is a laminated structure of one or more of a thermal insulation silicone layer and a thermal insulation ceramic layer. Of course, in some other embodiments, the heat insulation layer 30 may also be made of other heat insulation material layers, which are not described herein.

In some embodiments, the housing 10 includes an illuminating portion 12 and a handheld portion 13, the accommodating cavity 11 is disposed in the handheld portion 13, the illuminating portion 12 is provided with an electric light source 15, and the electric light source 15 is connected to the battery 14.

Specifically, the illumination portion 12 and the hand-held portion 13 are respectively distributed along the axial direction of the housing 10, and the illumination portion 12 is located at the front end of the hand-held portion 13. In addition, for convenience of use, the radial dimension of the hand-holding portion 13 can be reduced to be smaller than that of the illuminating portion 12, so as to facilitate hand-holding.

The accommodating chamber 11 is mainly used for accommodating the battery 14, and therefore, the accommodating chamber 11 is generally opened in the rear half of the housing 10, i.e., the hand-held portion 13. The receiving chamber 11 has an opening communicating with the outside, and the battery 14 can be filled into the receiving chamber 11 from the opening. In addition, the fire flashlight 100 further includes a push switch 40, and the push switch 40 is disposed at the opening to seal the opening. After the battery 14 is loaded into the accommodating cavity 11, the push switch 40 can be fixed at the opening by pushing, so that the battery 14 is limited in the accommodating cavity 11.

Further, an electric light source 15 is connected to the battery 14 through a wire to illuminate. That is, the electric light source 15 can emit light after being connected and connected with the battery 14, so as to realize the illumination function of the fire-fighting flashlight 100.

In some embodiments, the electrical light source 15 is an LED light source. In particular, the electric light source 15 is a high power LED light source, which refers to a light emitting diode with a large rated working power, and the power of the light emitting diode can reach 1W, 2W or even tens of watts. In addition, the high-power LED light source has the excellent characteristics of small volume, safety, low voltage, long service life, high electro-optic conversion efficiency, energy conservation, environmental protection and the like. Thereby, the illumination brightness of the fire fighting flashlight 100 can be improved.

Further, the high-power LED light source in the present application preferably adopts a golden light source. Since the longer the wavelength of the light source, the higher its transmittance, the longest the red wavelength but red light is easily confused with fire light, and cannot be used in the fire flashlight 100. Therefore, the light transmittance of the fire flashlight 100 can be ensured by using the golden yellow light with the wavelength being lower than the red light.

In some embodiments, the battery 14 is a storage battery, the handle 13 is provided with a charging interface 16 and a sealing plug (not shown), the charging interface 16 is connected to the storage battery, and the sealing plug can be hermetically filled in the charging interface 16.

To improve the overall IP protection rating of fire flashlight 100, battery 14 is preferably a battery. Of course, in other embodiments, the battery 14 may also be other batteries besides a storage battery, which is not described herein.

When the battery 14 is a storage battery, a charging interface 16 is provided on the handheld portion 13, and the charging interface 16 is connected to the storage battery so as to charge the storage battery. In addition, set up the sealing plug in the interface 16 that charges, can protect the interface 16 that charges, avoid the interface 16 that charges to lose efficacy because of getting damp or other reasons.

In some embodiments, the lighting portion 12 is further provided with a light-collecting barrel 17, the light-collecting barrel 17 is located in front of the electric light source 15 in the lighting direction of the electric light source 15, and the light-collecting barrel 17 is arranged coaxially with the housing 10. The light-gathering cylinder 17 can gather and radiate the light emitted by the electric light source 15 to the outside, so that the light can be radiated farther, and the fire flashlight 100 has a larger illumination range when being applied to fire rescue or escape.

Further, the light-condensing cylinder 17 is in a circular truncated cone shape, that is, the inner diameter of the light-condensing cylinder 17 gradually increases from one side close to the electric light source 15 to the other side. Thus, the light-collecting tube 17 can collect light emitted from the electric light source 15 more favorably, and the irradiation range of the lamp light can be made larger.

In some embodiments, the illuminating portion 12 is further provided with a front cover 18, and the front cover 18 is connected to a side of the light-gathering barrel 17 facing away from the electric light source 15. The front cover 18 is disposed at the foremost end of the housing 10 along the illumination direction, and the front cover 18 can protect the electric light source 15 and other illumination structures inside the housing 10, so as to improve the safety performance of the fire flashlight 100.

Based on the same concept as the fire-fighting flashlight 100 described above, the present application also provides a fire fighting device comprising the fire-fighting flashlight 100 as described above.

When this application specifically uses, at first load the battery in holding chamber 11 from the opening part to through press switch 40 to the battery is spacing in holding chamber 11. The storage battery is charged through the charging interface 16, and after charging is finished, the sealing plug is hermetically installed in the charging interface 16.

Further, the fire flashlight 100 is turned on, and the high-power LED light source emits light to start lighting. In addition, the light-gathering cylinder 17 gathers light, so that light emitted by the high-power LED light source can be further irradiated, and the illumination range of the fire-fighting flashlight 100 is enlarged.

The fire flashlight 100 and the fire fighting device in the above embodiments have at least the following advantages:

1) The heat conduction layer 20 can dissipate the internal temperature of the shell 10 of the fire-fighting flashlight 100, so that the situation that the temperature in the shell 10 is too high to damage all components of the fire-fighting flashlight 100 is avoided, and the heat dissipation performance and the safety performance of the fire-fighting flashlight 100 are improved;

2) The heat insulation layer 30 can insulate heat of the handheld part 13, so that discomfort of a user caused by overhigh temperature of the handheld part 13 in use is avoided;
