[0036] Please see Figures 1 to 3 This is a schematic diagram of a heat-insulated handheld fire-fighting device provided in an embodiment of this application. The heat-insulated handheld fire-fighting device includes a housing 10, a window area 11 formed on the housing 10, and a heat-insulating component 12 disposed opposite the window area 11. The heat-insulating component 12 includes a mounting member 20, and a first heat-insulating plate 21 and a second heat-insulating plate 22 connected to the mounting member 20. The first heat-insulating plate 21 and the second heat-insulating plate 22 are arranged parallel to each other and spaced apart from the window area 11. Both the first heat-insulating plate 21 and the second heat-insulating plate 22 are made of a light-transmitting heat-insulating material. The housing 10, the mounting member 20, and the light-transmitting heat-insulating material are all resistant to a high temperature of 260°C. The light-transmitting material is selected from glass, silicon, or germanium.
[0037] The arrangement of the heat insulation component 12 in relation to the window area 11 can be either placing the heat insulation component 12 directly in front of the window area 11 or placing the heat insulation component 12 directly behind the window area 11.
[0038] In the above embodiment, the heat-insulating handheld fire-fighting device includes a housing 10, with a window area 11 on the housing 10, and a heat-insulating component 12 corresponding to the window area 11. The heat-insulating component 12 includes a first heat-insulating plate 21 and a second heat-insulating plate 22 mounted on the window area 11 via mounting parts 20. The two heat-insulating plates are arranged in a front-to-back, spaced-apart configuration corresponding to the window area 11. This double-layer heat-insulating design effectively enhances the heat insulation effect of the handheld fire-fighting device, significantly improving the heat insulation capacity of the window area 11, which has the weakest heat insulation effect on the device. Both the first heat-insulating plate 21 and the second heat-insulating plate 22 are made of a light-transmitting heat-insulating material with a high-temperature resistance of 260℃. This material can be selected from glass, silicon, or germanium materials according to the needs of the actual application scenario, balancing light transmission performance and heat insulation protection requirements. It should be noted that the housing 10 can be a main structure formed by connecting multiple housing parts together with screws.
[0039] In some alternative embodiments, please refer to Figures 4 to 6 The mounting component 20 includes a closed-frame structure heat insulation bracket. A supporting step 23 is circumferentially arranged around the inner edges of opposite sides of the heat insulation bracket. The first heat insulation plate 21 and the second heat insulation plate 22 are respectively mounted on the supporting steps 23. The mounting component 20 uses a closed-frame structure heat insulation bracket, which covers the area where the window area 11 is located. A supporting step 23 is circumferentially arranged around the inner edges of opposite sides of the heat insulation bracket. These two sets of supporting steps 23 provide installation support for the first heat insulation plate 21 and the second heat insulation plate 22, respectively. The first heat insulation plate 21 is mounted on one side of the supporting step 23, and the second heat insulation plate 22 is mounted on the other side. This symmetrical structural design allows the two heat insulation plates to form a stable double-layer heat insulation layout behind the window area 11, improving the structural reliability of the overall heat insulation component 12.
[0040] The first heat insulation plate 21, the heat insulation bracket, and the second heat insulation plate 22 together define a closed cavity 24. The closed cavity 24 is evacuated to form a vacuum heat insulation cavity. The first heat insulation plate 21, the heat insulation bracket, and the second heat insulation plate 22 are all resistant to high temperatures of 260℃. The first heat insulation plate 21 and the second heat insulation plate 22 are respectively installed on the load-bearing steps 23 on both sides of the heat insulation bracket. The three together form a closed cavity 24. The closed cavity 24 is evacuated to form a vacuum heat insulation cavity. In this embodiment, the heat insulation bracket is rectangular and ring-shaped, with a size slightly larger than that of the window area 11. The supporting steps 23 are respectively located on the inner sides of the opposite ends of the heat insulation bracket. This simplifies the installation and fixing of the first heat insulation plate 21 and the second heat insulation plate 22. This structure of the vacuum heat insulation cavity, which is composed of the first heat insulation plate 21, the heat insulation bracket and the second heat insulation plate 22, can significantly improve the heat insulation performance of the heat insulation component 12 by utilizing the physical characteristic that the heat conduction efficiency is extremely low in the vacuum environment. It can effectively block the transfer of external heat in high-temperature fire-fighting scenarios, while ensuring that the light transmission and observation function of the window area 11 is not affected.
[0041] In some other alternative embodiments, please refer to Figure 3 The housing 10 is a heat-insulating protective shell, and an internal space 30 is formed to house the electronic components of the heat-insulating handheld fire fighting device. The housing 10 of the heat-insulating handheld fire fighting device is designed with a protective shell made of heat-insulating material, which provides better heat insulation protection for the electronic components housed in the internal space 30. Thus, the housing 10 can effectively block the external high-temperature environment, providing a reliable protective space for the internal electronic components, and effectively ensuring the stable operation and safety performance of various electronic components during high-temperature fire fighting operations. In this embodiment, the heat-insulating protective shell can be made of high-temperature resistant heat-insulating materials such as PPSU, which can withstand temperatures above 260°C and has both rigid structure and heat-barrier performance.
[0042] The electronic components include an imaging sensor chip, and the window area 11 serves as the incident window for imaging light. The electronic components contain an imaging sensor chip, and the window area 11 on the housing 10 serves as the incident channel for the input imaging light of this chip. External light can pass through the heat insulation component 12 in front through this window and be accurately projected onto the surface of the imaging sensor chip, thereby enabling the device to perform optical imaging in high-temperature environments. In this embodiment, the heat-insulated fire-fighting handheld device mainly refers to a handheld imaging device used in fire scene environments. To support its imaging function, a window area 11 for imaging light to enter needs to be provided on the housing 10. The window area 11 also becomes a weak area in the heat insulation of the fire-fighting handheld device. The design of the heat insulation component 12 can improve the heat insulation capability of the window area 11, which has the weakest heat insulation effect on the fire-fighting handheld device.
[0043] In some optional embodiments, the heat insulation component 12 is installed on the inner surface of the heat insulation protective shell, and the size of the heat insulation component 12 is greater than or equal to the size of the incident window. The heat insulation component 12 is fixed to the inner surface of the heat insulation protective shell by an inner mounting method, and the external dimensions of the heat insulation component 12 are designed to be no smaller than the size of the incident window on the shell 10. This size adaptation design ensures that the heat insulation component 12 completely covers the incident window area 11. On the one hand, it forms a composite heat insulation system with the protective shell through the inner mounting structure; on the other hand, it uses size redundancy to achieve full-range thermal protection for the window optical path, preventing heat from entering the equipment from the gap at the window edge under high temperature conditions, while allowing the imaging light to enter normally through the window without being limited by the size of the heat insulation component 12.
[0044] In some other alternative embodiments, please refer to Figure 7 and Figure 8 The imaging sensor chip includes an infrared sensor chip, and the first heat insulation plate 21 and the second heat insulation plate 22 are made of silicon or germanium. When the electronic components include an infrared camera 50, i.e., when the imaging sensor chip includes an infrared sensor chip, the first heat insulation plate 21 and the second heat insulation plate 22, which are matched with the infrared sensor chip, are made of silicon or germanium. Both silicon and germanium have good light transmittance in the infrared band, which can meet the transmission requirements of the infrared sensor chip for incident infrared light, and can also form a composite heat insulation system with the heat insulation bracket due to their own high temperature resistance properties. Among them, silicon is suitable for light transmission in the mid-infrared band, while germanium exhibits better light transmittance in the long-wave infrared region. The choice between the two can be adapted according to the specific operating band of the infrared sensor chip, thereby achieving the dual technical requirements of infrared imaging function and efficient heat insulation protection in high-temperature fire protection environments.
[0045] Optionally, the imaging sensor chip includes a white light sensor chip, and the first heat insulation plate 21 and the second heat insulation plate 22 are made of glass. When the imaging sensor chip includes a white light sensor chip, the first heat insulation plate 21 and the second heat insulation plate 22, which correspond to the white light sensor chip, are made of glass. This type of material has high light transmittance in the white light and laser bands, enabling white light, laser light, and other light rays to maintain good optical transmission efficiency when passing through the double-layer heat insulation plate and the window area 11. At the same time, the high temperature resistance of the glass material can form a composite heat insulation system with the heat insulation bracket. Among them, the chemical stability and structural density of the glass material provide reliable support for the white light imaging function in high-temperature fire protection scenarios, combining light transmittance and heat insulation protection.
[0046] In some optional embodiments, the heat-insulated fire-fighting handheld device also includes a display screen 31, which is positioned opposite the heat insulation component 12 and located on the side of the heat insulation component 12 away from the window area 11. The heat-insulated fire-fighting handheld device also includes a display screen 31, which is installed opposite the heat insulation component 12 and located on the other side of the heat insulation component 12 away from the window area 11. This layout design allows the display screen 31 to be physically isolated from the external high-temperature environment through the heat insulation component 12. This allows for clear observation of the content on the display screen 31 through the window area 11 and the heat insulation component 12, while the vacuum insulation cavity and double-layer insulation plate structure of the heat insulation component 12 effectively block heat radiation from the direction of the window area 11, preventing high temperatures from affecting the performance of the electronic components of the display screen 31 and ensuring stable operation of the display screen 31 within the heat-insulated protective shell.
[0047] In some alternative embodiments, a heat insulation layer 40 is provided on the outer side of the housing 10. This heat insulation layer 40 is made of a high-temperature resistant heat insulation material, capable of withstanding temperatures up to 260°C, and tightly covers the outer side of the housing 10. This outer heat insulation layer 40 effectively blocks heat conduction from the external high-temperature environment into the housing 10, forming a composite heat insulation system with the housing 10's own heat-insulating protective shell structure. When the equipment is used in high-temperature firefighting scenarios, the outer heat insulation layer 40 and the inner heat insulation component 12 construct a double heat insulation barrier from both the inner and outer sides of the housing 10, thereby providing more comprehensive high-temperature protection for the electronic components inside the housing 10, enabling the equipment to operate continuously and stably in complex fire environments. In this embodiment, the heat insulation layer 40 can be a heat-insulating soft rubber sheet made of materials such as liquid silicone, which is elastically and tightly wrapped around the outer side of the housing 10, preventing heat from entering through gaps, screws, or other locations between multiple housings 10.
[0048] The above are merely specific embodiments of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
