DETAILED DESCRIPTION
[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0018] See also Figure 1-4 The utility model provides a technical solution: a defogging and waterproof LED floodlight, comprising a shell 1, a fixing frame 2 is connected to the surface of the shell 1, a defogging and waterproof mechanism 3 is arranged on one side of the surface of the shell 1, a lighting mechanism 4 is arranged inside the shell 1, and a sealing strip 5 is connected to the surface of the fixing frame 2;
[0019] The demisting and waterproofing mechanism 3 includes a hollow bolt 301, a hydrophobic breathable membrane 302, a hollow block 303, a sealing ring 304, a slide groove 305, a limiting groove 306, a spring 307 and a baffle 308. The surface of the shell 1 is threadedly connected with the hollow bolt 301, the surface of the hollow bolt 301 is embedded with the hydrophobic breathable membrane 302, one end of the hollow bolt 301 is connected with the hollow block 303, the surface of the hollow bolt 301 is sleeved with a sealing ring 304, a slide groove 305 is provided on one side of the surface of the hollow block 303, a limiting groove 306 is provided inside the hollow block 303, a spring 307 is embedded inside the hollow block 303, and a baffle 308 is embedded on the surface of the hollow block 303. When demisting and waterproofing the transparent lamp, the baffle 308 on one side of the slide groove 305 is first pushed, and when the baffle 308 moves, The spring 307 inside the limiting groove 306 is continuously squeezed, and the spring 307 is deformed under the force. When the baffle 308 is pushed to a certain position, a proper amount of desiccant particles are added to the inside of the hollow block 303, and then the baffle 308 is loosened, and the spring 307 drives the baffle 308 to reset, and then the sealing ring 304 is put on the hollow bolt 301, and then one end of the hollow bolt 301 is connected around the threaded hole on the surface of the shell 1. Subsequently, when the floodlight is used, a hydrophobic and breathable membrane 302 is added to the hole on the surface of the hollow bolt 301, which can allow air to enter the inside of the shell 1. While balancing the internal and external pressures, it can effectively prevent water vapor, smoke, dust and other liquids from invading. When moisture is generated inside the shell 1, the desiccant particles inside the hollow block 303 can absorb the moisture, thereby achieving the effect of demisting and waterproofing.
[0020] Furthermore, the spring 307 is embedded in the limiting groove 306, the hollow block 303 is provided with six groups, and the hollow bolts 301 are provided with four groups. Through the setting of the spring 307, when in use, when the spring 307 rebounds and resets, it can drive the baffle 308 to move and reset, thereby facilitating the subsequent baffle 308 to block the desiccant particles inside the hollow block 303 to prevent them from falling out.
[0021] Furthermore, one end of the baffle 308 is embedded in the interior of the slide groove 305, and the hollow block 303 is a porous structure. Through the setting of the hollow block 303, when in use, the hollow block 303 is used to store desiccant particles, and the hollow block 303 is a porous structure. When the interior of the shell 1 is moist, the desiccant particles can absorb the moisture inside the shell 1 through the holes on the surface of the hollow block 303, thereby keeping the interior of the shell 1 dry, effectively avoiding the fogging of the floodlight when in use.
[0022] Furthermore, the lighting mechanism 4 includes a power supply 401, a lamp board 402, a glass plate 403, a reinforcing layer 404 and a self-cleaning film 405. The power supply 401 is installed inside the shell 1, the lamp board 402 is embedded inside the shell 1, the glass plate 403 is embedded inside the shell 1, the reinforcing layer 404 is embedded inside the shell 1, and the self-cleaning film 405 is embedded inside the shell 1. By setting the power supply 401, the lamp board 402, the glass plate 403, the reinforcing layer 404 and the self-cleaning film 405, when using When lighting is performed, first connect the power supply 401 to the light board 402, then the light board 402 lights up, and the light emitted by the light board 402 passes through the glass plate 403, the reinforcing layer 404 and the self-cleaning film 405 in turn. The reinforcing layer 404 can increase the brightness emitted by the light board 402, increase the range of lighting, and absorb harmful rays, while the self-cleaning film 405 has the properties of deodorization, antibacterial, anti-mildew, and anti-fouling, which can keep one side of the glass plate 403 clean and increase the cleanliness of the equipment.
[0023] Furthermore, the power supply 401 is electrically connected to the light board 402, the glass plate 403 is bonded to the reinforcing layer 404, and the material of the reinforcing layer 404 is nano-barium sulfate. Through the setting of the reinforcing layer 404, when in use, the material of the reinforcing layer 404 is nano-barium sulfate, and nano-barium sulfate has the advantages of strong chemical inertness, good stability and the ability to absorb harmful rays, thereby increasing the brightness emitted by the light board 402, increasing the range of lighting, and absorbing harmful rays during lighting.
[0024] Working principle: First, when lighting, connect the power supply 401 to the light board 402, then the light board 402 lights up, and the light emitted by the light board 402 passes through the glass plate 403, the reinforcing layer 404 and the self-cleaning film 405 in turn. The reinforcing layer 404 can increase the brightness emitted by the light board 402, increase the range of lighting, and absorb harmful rays, while the self-cleaning film 405 has the characteristics of deodorization, antibacterial, anti-mildew, and anti-fouling, which can keep one side of the glass plate 403 clean and increase the cleanliness of the equipment. Then, when defogging and waterproofing the transparent lamp, first push the baffle 308 on one side of the slide groove 305. The movement of the baffle 308 continuously squeezes the spring 307 inside the limit groove 306 at the same time, and the spring 307 is When the force is deformed and the baffle 308 is pushed to a certain position, a proper amount of desiccant particles are added to the inside of the hollow block 303, and then the baffle 308 is loosened, and the spring 307 drives the baffle 308 to reset, and then the sealing ring 304 is put on the hollow bolt 301, and then one end of the hollow bolt 301 is connected around the threaded hole on the surface of the shell 1. Subsequently, when the floodlight is used, a hydrophobic breathable membrane 302 is added to the hole on the surface of the hollow bolt 301, which can allow air to enter the inside of the shell 1, balance the internal and external pressures, and effectively prevent the invasion of water vapor, smoke, dust and other liquids. When moisture is generated inside the shell 1, the desiccant particles inside the hollow block 303 can absorb the moisture, thereby achieving the effect of demisting and waterproofing.
