[0019] Furthermore, a method for using an LED lamp protection device is provided, wherein the method comprises the following steps:

[0020] S1: Installation and detection: First, fix the main body to the required position through the fixing frame, then start the humidity sensor and the main body. When it is raining or in an overly humid environment, the humidity sensor detects the external humidity and transmits it to the electric push rod, which controls the top plate to slide downward;

[0021] S2: Sliding separation: When the top plate slides downward, the push plates are pushed outward by multiple push rods. When the multiple push plates slide outward, the sliding ring is pushed upward. When the sliding ring slides upward, it is separated from the flexible layer.

[0022] S3: Blocking waterproofing: At this time, the flexible layer will be pushed by the swing plate and the return spring on the swing plate so that the flexible layer is located at the outer wall of the rectangular hole 1, thereby achieving the purpose of waterproofing the main body.

[0023] The present invention has the following beneficial effects:

[0024] 1. In the present invention, when the humidity sensor detects the humidity and drives the top plate to slide downward through the electric push rod, the downward sliding of the top plate will drive multiple connecting plates to slide downward synchronously. When the connecting plate slides downward, it will drive the rubber shaft to slide downward. Since the last conical block on the rubber shaft is fixedly connected to the rubber shaft, when the rubber shaft slides downward, it will be pulled by the rubber shaft through the last conical block, which will cause multiple conical blocks to bend and squeeze the airbag. When the airbag is squeezed, the gas inside it will enter the inside of the annular cavity under the squeezing of multiple conical blocks. At the same time, when the top plate slides downward, it will drive the L ring through multiple connecting shafts. Slide downward inside the annular cavity and seal the rectangular hole 2. Then, when the gas inside the flexible layer enters the annular cavity, a gas-filled buffer layer will be formed in the annular cavity and at one of the multiple rectangular holes. When the multiple rectangular holes 2 are closed by the L ring, the gas inside the annular cavity can hinder the heat transfer between the inside of the main body and the external environment, thereby reducing the temperature difference between the inside and outside of the main body, reducing the external gas entering the main body due to the temperature difference, causing water mist or water vapor condensation in the main body, and reducing the damage to the main body during operation due to the entry of water vapor, thereby improving the protection performance of the main body.

[0025] 2. In the present invention, when the top plate slides downward and drives the L-ring to slide downward inside the annular cavity through multiple connecting shafts, the downward sliding of the L-ring will drive multiple piston rods to slide down synchronously. When the piston rod slides downward, the gas between the inner wall of the bottom of the piston hole and the piston rod will be squeezed. When the gas inside the piston hole is squeezed, it will enter the flexible layer through the connecting pipe. When the gas inside the multiple piston holes enters the flexible layer, the flexible layer will be in a semi-expanded state. At the same time, when the sliding of the push rod drives the sliding ring to slide upward through the push plate, the upward movement of the sliding ring will be separated from the flexible layer. When the flexible layer is separated from the sliding ring, the swing plate will drive the expanded flexible layer to expand outward under the elasticity of the reset spring 2. Then, when the external airflow flows and When blowing onto the flexible layer, the flexible layer will drive the swing plate to swing under the blowing of the airflow, and when the swing plate is swinging, it will drive the flexible layer to swing at one place of the rectangular hole. When the expanded flexible layer swings at one place of the rectangular hole, it can disrupt the flow direction of the airflow to the rectangular hole 1, so that the airflow cannot directly and smoothly enter the annular cavity and plays a certain blocking and buffering role, reducing the impact force of the airflow blowing into the annular cavity through multiple rectangular holes 1 during flow, thereby reducing the possibility of weakening the effect of the air buffer layer caused by the gas in the annular cavity being blown out when the external gas flows, thereby maintaining the effect of the air buffer layer formed in the annular cavity, enhancing the stability of the air buffer layer in the annular cavity and the effect of balancing the temperature difference between the inside and the outside.

[0026] 3. In the present invention, when the L ring slides downward inside the annular cavity, the downward movement of the L ring will push the side of the rotating plate through the vertical plate and make the rotating plate rotate on the surface of the limit shaft. When the multiple rotating plates rotate, the scraper ring will be driven to slide upward inside the annular cavity through the auxiliary rod, wherein the tension spring 2 on the scraper ring will push the scraper ring to slide upward under its own elastic force. When the scraper ring slides upward, it will scrape the inner wall of the annular cavity. Then, when the temperature difference between the inside and the outside disappears and the electric push rod drives the top plate to slide upward and reset, the reset of the top plate will drive the rotating plate to rotate through the L ring, and the rotating plate will rotate when it rotates. The scraper ring will be pushed to slide on the inner wall of the annular cavity and scrape and clean the water vapor on the inner wall of the annular cavity, thereby reducing the situation where the humid air entering the annular cavity with high humidity through multiple rectangular holes and the water vapor may condense into water droplets on the side wall of the annular cavity after the temperature changes. The formation of water droplets during long-term use may affect the air buffer layer in the annular cavity or even enter the lamp body, thereby reducing the accumulation of water vapor on the cavity wall, thereby reducing the possibility of water droplet formation, thereby protecting the stability of the device.

[0027] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] A method for using an LED lamp protection device, the LED lamp protection device, the method comprising the following steps:

[0056] S1: Installation and detection: First, fix the main body 1 to the required position through the fixing frame 101, and then start the humidity sensor 206 and the main body 1. When the outside is in a rainy or excessively humid environment, the humidity sensor 206 detects the external humidity and transmits it to the electric push rod 207 and controls the top plate 201 to slide downward through the electric push rod 207;

[0057] S2: Sliding separation: When the top plate 201 slides downward, the plurality of push rods 202 push the push plate 401 to slide outward, and when the plurality of push plates 401 slide outward, the slide ring 403 is pushed to slide upward, and when the slide ring 403 slides upward, it is separated from the flexible layer 404;

[0058] S3: Blocking and waterproofing: At this time, the flexible layer 404 will be pushed by the swing plate 405 and the return spring on the swing plate 405 so that the flexible layer 404 is located at the outer wall of the rectangular hole 104, thereby achieving the purpose of waterproofing the main body 1.

[0059] When in use, first fix the main body 1 to the required position through the fixing frame 101, and then start the humidity sensor 206 and the main body 1. When the outside is in a rainy or overly humid environment, the humidity sensor 206 will detect the external humidity and transmit it to the electric push rod 207, and control the top plate 201 to slide downward through the electric push rod 207. When the top plate 201 slides downward, the push plate 401 will be pushed to slide outward through multiple push rods 202. When the multiple push plates 401 slide outward, they will push the sliding ring 403 to slide upward. When the sliding ring 403 slides upward, it will separate from the flexible layer 404. At this time, the flexible layer 404 will be pushed by the swing plate 405 and the reset spring on the swing plate 405 so that the flexible layer 404 is at the outer wall of the rectangular hole 104, thereby achieving the purpose of waterproofing the main body 1.

[0060] When the humidity sensor 206 detects the humidity and drives the top plate 201 to slide downward through the electric push rod 207, the downward sliding of the top plate 201 will drive the multiple connecting plates 301 to slide downward synchronously. When the connecting plate 301 slides downward, it will drive the rubber shaft 302 to slide downward. Since the last conical block 303 on the rubber shaft 302 is fixedly connected to the rubber shaft 302, when the rubber shaft 302 slides downward, the last conical block 303 will be pulled by the rubber shaft 302, causing the multiple conical blocks 303 to bend and squeeze the airbag 304. When the airbag 304 is squeezed, the gas inside it will enter the interior of the annular cavity 103 under the squeezing of the multiple conical blocks 303. At the same time, when the top plate 201 slides downward, it will pass through the multiple connecting plates 301. The connecting shaft 204 drives the L-ring 205 to slide downward inside the annular cavity 103 and seal the rectangular hole 2 105. Then, when the gas inside the flexible layer 404 enters the annular cavity 103, a gas-filled buffer layer will be formed inside the annular cavity 103 and at the plurality of rectangular holes 1 104. When the plurality of rectangular holes 2 105 are sealed by the L-ring 205, the gas inside the annular cavity 103 can hinder the heat transfer between the inside of the main body 1 and the external environment, thereby reducing the temperature difference between the inside and outside of the main body 1, reducing the situation where the external gas enters the main body 1 due to the temperature difference, resulting in water mist or water vapor condensation in the main body 1, and reducing the situation where the main body 1 is damaged during operation due to the entry of water vapor, thereby improving the protection performance of the main body 1.

[0061] When the top plate 201 slides downward and drives the L ring 205 to slide downward inside the annular cavity 103 through the multiple connecting shafts 204, the downward sliding of the L ring 205 will drive the multiple piston rods 601 to slide down synchronously. When the piston rod 601 slides downward, the gas between the bottom inner wall of the piston hole 602 and the piston rod 601 will be squeezed. When the gas inside the piston hole 602 is squeezed, it will enter the flexible layer 404 through the connecting pipe 603. When the gas inside the multiple piston holes 602 enters the flexible layer 404, the flexible layer 404 will be semi-expanded. At the same time, when the sliding of the push rod 202 drives the sliding ring 403 to slide upward through the pushing plate 401, the upward movement of the sliding ring 403 will be separated from the flexible layer 404. When the flexible layer 404 is separated from the sliding ring 403, the swing plate 405 will drive the expanded flexible layer 404 to expand outward under the elasticity of the reset spring 2. Then, when When the external airflow flows and blows onto the flexible layer 404, the flexible layer 404 will drive the swing plate 405 to swing under the blowing of the airflow. When the swing plate 405 is shaking, it will drive the flexible layer 404 to swing at the rectangular hole 104. When the expanded flexible layer 404 swings at the rectangular hole 104, it can disrupt the flow direction of the airflow to the rectangular hole 104, so that the airflow cannot directly and smoothly enter the annular cavity 103 and plays a certain blocking and buffering role, reducing the impact force of the airflow blowing into the annular cavity 103 through multiple rectangular holes 104 when flowing, thereby reducing the possibility of the air buffer layer weakening due to the gas in the annular cavity 103 being blown out when the external gas flows, thereby maintaining the effect of the air buffer layer formed in the annular cavity 103, enhancing the stability of the air buffer layer in the annular cavity 103 and the effect of balancing the temperature difference between the inside and the outside.

[0062] When the L ring 205 slides downward inside the annular cavity 103, the downward movement of the L ring 205 will push the side of the rotating plate 502 through the vertical plate 501 and make the rotating plate 502 rotate on the surface of the limit shaft 503. When multiple rotating plates 502 rotate, they will drive the scraper ring 505 to slide upward inside the annular cavity 103 through the auxiliary rod 504. The tension spring 2 on the scraper ring 505 will push the scraper ring 505 to slide upward under its own elastic force. When the scraper ring 505 slides upward, it will scrape the inner wall of the annular cavity 103. Then, when the temperature difference between the inside and the outside disappears and the electric push rod 207 drives the top plate 201 to slide upward and reset, the reset of the top plate 201 will drive the rotating plate 502 to move forward through the L ring 205. The rotating plate 502 rotates, and when it rotates, it pushes the scraper ring 505 to slide on the inner wall of the annular cavity 103 through the scraper ring 505 and scrapes and cleans the water vapor on the inner wall of the annular cavity 103, thereby reducing the humid air entering the annular cavity 103 through multiple rectangular holes 104. When the external air is humid and enters the interior of the annular cavity 103 through multiple rectangular holes 104, the humid air entering the annular cavity 103 may condense into water droplets on the side wall of the annular cavity 103 after the temperature changes. The formation of water droplets during long-term use may affect the air buffer layer in the annular cavity 103 or even enter the lamp body, thereby reducing the accumulation of water vapor on the cavity wall, thereby reducing the possibility of water droplet formation, thereby protecting the stability of the device.

[0063] Then, the water vapor scraped off by the scraper ring 505 will be discharged outward through the multiple water outlets at the bottom of the annular cavity 103, and the water outlets will be blocked after the air bag 304 is squeezed.
