[0014] The present invention has the following beneficial effects:

[0015] (1) An integrated ceiling ventilation structure for indoor use in commercial buildings. After the motor is started, it will drive the sleeve gear one to rotate. The sleeve gear one will drive the connecting sleeve to rotate through the sleeve gear two. The connecting sleeve will drive the threaded sleeve to rotate on the surface of the fixed shaft two. The rotation of the threaded sleeve will drive the two sliding plates to approach each other. The two sliding plates will drive the two wind shields to approach each other through the limit frame. During the movement, the wind shield will also move upward due to the limiting action of the limit frame and the limit plate, and finally make the two wind shields contact, and the top of the wind shield will also contact the top of the inner wall of the shell, thereby blocking the air inhaled by the fan to reduce the air intake. This design blocks the air inhaled by the fan by the wind shield, thereby reducing the air intake, so that the device can adjust the ventilation volume according to the humidity of the outdoor air, thereby maintaining the comfort and health of the indoor environment.

[0016] (2) An integrated ceiling ventilation structure for indoor use in commercial buildings. When the outdoor environment is rainy or the air is relatively humid, part of the moisture in the air will be absorbed by the water absorption board before the humid air is sent into the room. When the water absorption rate of the water absorption board is greater than the air drying rate, it means that the air humidity is too high. Bringing a large amount of external air into the room will cause the indoor humidity to be too high. At this time, the water absorption board will absorb moisture and become heavier, and it will also expand slightly, thereby increasing its wind receiving area. Therefore, the water absorption board will increase its own weight and compress the spring under the action of wind force, and move downward together. The water absorption board moves The downward movement will compress the gas in the fixed sleeve one and pass the gas into the air duct, the air duct will pass the air into the fixed sleeve two, the air passed into the fixed sleeve two will push the power connector to the front and finally contact with the motor, thereby energizing the motor, the power connector will drive the air baffle to move during the movement, and after the power connector contacts the motor, the through hole on the right side of the shell will be blocked and sealed. This design can automatically detect the air humidity to determine whether the motor needs to be started, so that the motor will only be started when it is needed, thereby reducing the use cost of the device and reducing the waste of resources.

[0017] (3) An integrated ceiling ventilation structure for indoor use in commercial buildings. When the limit frame is moved upward by the windshield to a position close to the contact position of the two windshields, the limit frame will contact the bottom of the pressure plate 1. As the two windshields contact each other, the limit frame will push the pressure plate 1 upward. The pressure plate 1 will compress the air in the sliding plate and push the air into the air guide hose. The air guide hose will ventilate the air into the outer shell. The air entering the outer shell will push the limit ring to the left. During the movement, the limit ring will move with the sleeve tooth 21 and compress the spring 2. At this time, the sleeve tooth 2 will disengage from the sleeve tooth 1, and the connecting sleeve moves. After the sleeve tooth two is reset, it will no longer be limited by the limit rod one and cannot rotate. At this time, the sleeve tooth two, the fixed shaft two and the threaded sleeve can rotate freely. Therefore, the coil spring will drive the threaded sleeve to reverse, so that the two wind deflectors are reset, and then the device can resume normal ventilation.

[0018] (4) An integrated ceiling ventilation structure for indoor use in commercial buildings. The sliding plate will pull the traction rope during movement, and the traction rope will eventually pull the scraper to move and compress the spring four through the limiting action of a number of limiting seats. The scraper will scrape the dust on the filter plate during movement to prevent the dust from being soaked by humid air and sticking to the filter plate. The scraped dust can be discharged from the inside of the device through the dust outlet channel. When the device is used normally, the filter plate will gradually accumulate dust. As the dust accumulates, the area available for air to pass through will decrease, thereby increasing wind resistance. Therefore, the filter plate will gradually drive the pressure plate two to move downward and compress the spring during use. Spring five, the filter plate moves downward and will first pull the offset rod and compress spring three, so that it will not drive the scraper to move during the downward movement. The filter plate will contact the top of the water absorption plate during the downward movement. As the filter plate continues to move downward, it will drive the water absorption plate to move downward to start the motor, and finally drive the scraper to clean the dust on the filter plate. This design can directly clean the dust on the filter plate when the air is humid, preventing the dust from being soaked by the humid air and sticking to the filter plate, and can also automatically determine whether the filter plate needs to be cleaned according to the degree of dust accumulation, thereby improving the convenience and practicality of the device.

The outer surface of the air baffle 111 is slidably connected to the inner wall of the shell 101.

During the movement, the wind shields 212 will also move upward through the limiting action of the limiting frame 211 and the limiting plate 213, so that the two wind shields 212 are finally in contact with each other, and the top of the wind shield 212 will also contact the top of the inner wall of the shell 101, thereby blocking the air inhaled by the fan 103 to reduce the amount of air entering.

After the second sleeve tooth 203 is reset, it will no longer be limited by the limit rod 1 206 and cannot rotate. At this time, the second sleeve tooth 203, the second fixed shaft 205 and the threaded sleeve 208 can rotate freely, so the coil spring 209 will drive the threaded sleeve 208 to reverse, so that the two wind baffles 212 are reset, and the device can resume normal ventilation.

[0040] The inner wall of the sliding plate 210 is slidably connected to the outer surface of the offset rod 302, the spring three 303 is fixedly connected to the outer surface of the offset rod 302 at the end away from the sliding plate 210, the spring three 303 is fixedly connected to the outer surface of the sliding plate 210 at the side close to the sliding plate 210, a plurality of limit seats 304 are fixedly connected to the inner wall of the outer shell 101, the outer surface of the traction rope 301 is slidably connected to the inner wall of the limit seat 304, the traction rope 301 is fixedly connected to the scraper 305 at the end away from the offset rod 302, the inner wall of the scraper 305 is slidably connected to the limit rod two 307, and the outer surface of the limit rod two 307 is sleeved with a spring four 306.

[0041] The outer surface of the limiting rod 307 is fixedly connected to the filter plate 308, the outer surface of the scraper 305 is slidably connected to the outer surface of the filter plate 308, the bottom of the filter plate 308 is fixedly connected to the ash outlet channel 309, the top and bottom of the ash outlet channel 309 are fixedly connected to the shield plate 1 310, the outer surface of the shield plate 1 310 is slidably connected to the inner wall of the shell 101, the left and right sides of the filter plate 308 are fixedly connected to the shield plate 2 311, the outer surface of the shield plate 2 311 is slidably connected to the inner wall of the shell 101, the shield plate 2 311 is fixedly connected to the side away from the filter plate 308 with the pressure plate 2 312, the pressure plate 2 The bottom of 312 is fixedly connected with a spring five 313, the inner wall of the pressure plate two 312 is slidably connected with a fixing plate 314, the bottom of the spring five 313 is fixedly connected with the top of the fixing plate 314, and the fixing plate 314 is fixedly connected with the outer surface of the shell 101 on the side close to the shell 101.

The downward movement of the filter plate 308 will preferentially pull the offset rod 302 and compress the spring 303, so that it will not drive the scraper 305 to move during the downward movement. When the filter plate 308 moves downward, it will contact the top of the water absorption plate 104. As the filter plate 308 continues to move downward, it will drive the water absorption plate 104 to move downward to start the motor 201, and finally drive the scraper 305 to clean the dust on the filter plate 308.

It can also automatically determine whether the filter plate 308 needs to be cleaned according to the degree of dust accumulation, thereby improving the convenience and practicality of the device.

[0042] A specific application of this embodiment is:

[0043] When using the device, first install the device to the designated position, then start the fan 103 to supply air to the room. When the outdoor environment is rainy or the air is relatively humid, part of the moisture in the air will be absorbed by the water absorption plate 104 when the humid air is supplied to the room. When the water absorption speed of the water absorption plate 104 is greater than the air drying speed, it means that the air humidity is too high. Bringing a large amount of external air into the room will cause the indoor humidity to be too high. At this time, the water absorption plate 104 absorbs moisture and becomes heavier, and it will also expand slightly, thereby increasing its wind receiving area. Therefore, the water absorption plate 104 will compress the spring 106 and move downward under the action of its own gravity and wind force. The downward movement of the water absorption plate 104 will compress The gas in the fixing sleeve 107 is passed into the air duct 108, and the air duct 108 passes the air into the fixing sleeve 2 109. The air passed into the fixing sleeve 2 109 pushes the electrical connector 110 to the front and finally contacts the motor 201, thereby energizing the motor 201. The electrical connector 110 drives the air baffle 111 to move together during the movement, and after the electrical connector 110 contacts the motor 201, the through hole on the right side of the housing 101 is blocked and sealed. This design can automatically detect the air humidity to determine whether the motor 201 needs to be started, so that the motor 201 is started only when it needs to work, thereby reducing the use cost of the device and reducing the waste of resources.

[0044] After the motor 201 is started, it will drive the sleeve gear 1 202 to rotate, and the sleeve gear 1 202 will drive the connecting sleeve 204 to rotate through the sleeve gear 203, and the connecting sleeve 204 will drive the threaded sleeve 208 to rotate on the surface of the fixed shaft 205. The rotation of the threaded sleeve 208 will drive the two sliding plates 210 to approach each other, and the two sliding plates 210 will drive the two windshield plates 212 to approach each other through the limiting frame 211. During the movement, the windshield plates 212 will also move upward through the limiting effect of the limiting frame 211 and the limiting plate 213, and finally the two windshield plates 212 will contact each other, and the top of the windshield plates 212 will be moved upward by the limiting effect of the limiting frame 211 and the limiting plate 213. The windshield 212 will also contact the top of the inner wall of the housing 101, thereby blocking the air sucked in by the fan 103 to reduce the amount of air entering. This design blocks the air sucked in by the fan 103 through the windshield 212, thereby reducing the amount of air entering, so that the device can adjust the ventilation volume according to the humidity of the outdoor air, thereby maintaining the comfort and health of the indoor environment. When the limit frame 211 is moved upward by the windshield 212 to a position close to the contact position of the two windshields 212, the limit frame 211 will contact the bottom of the pressure plate 214. As the two windshields 212 contact each other, the limit frame 211 will push the pressure plate 214 upward. 14, the pressure plate 1 214 will compress the air in the sliding plate 210 and push the air into the air guide hose 215, the air guide hose 215 will pass the air into the housing 101, the air passed into the housing 101 will push the limit ring 216 to the left, the limit ring 216 will move with the sleeve tooth 203 and compress the spring 207 during the movement, at this time the sleeve tooth 203 will be disengaged from the sleeve tooth 1 202, and the connecting sleeve 204 will be limited by the limit rod 1 206 after moving, and thus can no longer rotate, and when the air is no longer humid, the water absorption plate 104 is air-dried and reset, the electric head 110 is connected. The air baffle 111 will also be reset and driven to reset together. After the air baffle 111 is reset, the through hole on the right side of the housing 101 is no longer sealed. At this time, the air in the air guide hose 215 and the housing 101 can be discharged from the through hole. The second sleeve tooth 203 can be reset under the action of the second spring 207. After the second sleeve tooth 203 is reset, it will no longer be limited by the limit rod 1 206 and cannot rotate. At this time, the second sleeve tooth 203, the second fixed shaft 205 and the threaded sleeve 208 can rotate freely. Therefore, the coil spring 209 will drive the threaded sleeve 208 to reverse, so that the two air baffles 212 are reset, and then the device can resume normal ventilation.

[0045] The sliding plate 210 will pull the traction rope 301 during the movement, and the traction rope 301 will eventually pull the scraper 305 to move and compress the spring four 306 through the limiting effect of several limiting seats 304. The scraper 305 will scrape the dust on the filter plate 308 during the movement to prevent the dust from being soaked by the humid air and sticking to the filter plate 308. The scraped dust can be discharged from the inside of the device through the dust outlet channel 309. When the device is used normally, the filter plate 308 will gradually accumulate dust. As the dust accumulates, the area available for air to pass through will decrease, thereby increasing the wind resistance. Therefore, the filter plate 308 will gradually drive the pressure plate 2 312 to move downward and compress the spring five 313 during use, and the filter plate 308 moves downward. The movement will preferentially pull the offset rod 302 and compress the spring three 303 so that it will not drive the scraper 305 to move during the downward movement. The filter plate 308 will contact the top of the water absorption plate 104 during the downward movement. As the filter plate 308 continues to move downward, it will drive the water absorption plate 104 to move downward to start the motor 201, and finally drive the scraper 305 to clean the dust on the filter plate 308. This design can directly clean the dust on the filter plate 308 when the air is humid, preventing the dust from being soaked by the humid air and sticking to the filter plate 308, and can also automatically determine whether the filter plate 308 needs to be cleaned according to the degree of dust accumulation, thereby improving the convenience and practicality of the device.
