[0016] 1. In the present invention, when the electric telescopic plate is retracted, the electric telescopic plate will also drive the bottom telescopic plate to retract.

This state is for autonomous purification of the surrounding environment. It is driven by a driving shaft. Because the position of the driven bevel gear on the surface of the driving shaft is set, it is convenient for the connection of the filter layer after rotation.

[0018] 3. The present invention drives the rotating plate to rotate through the internal motor of the vertical axis, so that the connecting frame pulls the bottom filter layer to rotate. Because each group of filter layers is connected by a pull rope, the remaining groups will also be pulled one by one and gradually unfolded into a state of six equal parts, with the air inlet facing all around. When storing, through the push of the connecting frame and the obstruction of the vertical plate, all the filter layers that are rotated open will gradually gather on one side of the vertical plate to form a vertical row, so that it is convenient for the vertical row of air inlets to correspond to the wind direction of the ambient wind. The fan in the air inlet is driven by the ambient wind to rotate, and the air is introduced into the filter for processing.

[0019] 4. The present invention determines the wind direction through a wind vane, detects the angle of the wind vane offset through an angle sensor, and transmits a signal to a drive motor. The drive motor drives the drive gear to rotate and engage with the gear ring, so that the vertical plate pushes all the filter layers to rotate, and the drive shaft and the air outlet pipe also rotate synchronously to make the position of the air inlet correspond to the natural wind.

[0020] 5.

[0036] In this embodiment, a transmission belt 34 is installed at the driving shaft 41 of the fan 33 inside the air outlet 32, and a pulley at the other end of the transmission belt 34 is rotatably installed on the top of the air outlet 32, and the belt of the transmission belt 34 slides through the outer shell of the air outlet 32, and the pulley at the upper end of the transmission belt 34 is fixed with a shaft 35, and the transmission assembly 4 also includes an active bevel gear 42, and an active bevel gear 42 is fixed on the surface of the driving shaft 41 corresponding to the position of each air outlet 32, and one side of the active bevel gear 42 is meshed with A driven bevel gear 44 is connected, and a fixing plate 43 is installed on the back of the driven bevel gear 44. The fixing plate 43 is fixed on the connecting layer between the two groups of air outlets 32. A card frame 45 is rotatably installed on the back of the fixing plate 43, and the card frame 45 is fixedly connected to the driven bevel gear 44. A card block 46 is fixed to one end of the shaft 35 facing the card frame 45, and the card block 46 is slidably connected to the inside of the card frame 45. The shape of the card frame 45 and the card block 46 is the same as the rotation path of the air outlet 32. In fact, a motor for driving the driving shaft 41 to rotate is installed at the bottom. Here, except for the topmost driven bevel gear 44 and the card frame 45, the positions of the following ones correspond to the positions after the filter layer 3 rotates. In short, the six groups of filter layers 3 can be expanded into six equidistantly distributed filter layers 3 by the driving component 5, and the positions of the air inlets 31 are also equidistantly set, but the upper and lower heights are different. Similarly, the driving component 5 can also merge the filter layers 3 into a vertical direction. After the filter layer 3 is expanded, the top shafts 35 of the remaining five groups of air outlets 32 are just connected to the inside of the card frame 45 through the movement of the card block 46. The driving shaft 41 can drive the active bevel gear 42 to rotate and mesh with the driven bevel gear 44, and then drive the fan 33 at the position of the air outlet 32 ​​through the transmission of the transmission belt 34. This state is for autonomous purification of the surrounding environment, and is driven by a driving shaft 41.

[0037] In this embodiment, a channel is provided inside the filter layer 3 at positions corresponding to the air inlet 31 and the air outlet 32, the upper and lower ends of the channel of the filter layer 3 are covered by a connecting ring 36, a scraper 37 is fixed on one side of the channel of the filter layer 3 between the intervals of the filter assembly 6, and an electric telescopic plate 38 is fixed on the other side of the channel of the filter layer 3, the connecting ring 36 at the bottom of the filter layer 3 is located at the interval of the filter assembly 6 and a bottom telescopic plate 39 is provided, and the extended end of the bottom telescopic plate 39 is fixedly connected to the extended end of the electric telescopic plate 38, and the bottom of the filter assembly 6 is fixedly connected to the bottom of the filter assembly 6. The two ends of the fixing rod 61 are fixedly connected to the two sides of the connecting layer. The bottoms of the connecting ring 36, the electric telescopic plate 38 and the scraper 37 are all provided with elastic rubber strips 310. The fixing rod 61 can pass through the rubber strip 310. The two connecting rings 36, the scraper 37 and the electric telescopic plate 38 form a channel for the air sent in from the air inlet 31 to pass through the three-layer filter and then be sent out from the air outlet 32. In this structure, first, the bottom part is the bottom telescopic plate 39, and the extended end is connected to the extended end of the electric telescopic plate 38, so in the electric telescopic plate When the retractable plate 38 is retracted, the bottom retractable plate 39 is also retracted. At this time, the side and bottom of the channel close to the filter are opened, and the connecting ring 36 cleans the surface of the filter through the scraper 37 when the driving component 5 or the transmission component 4 rotates around the filter assembly 6, scrapes off the adsorbed dust particles, and drops them from the bottom into the collection box. This part of the cleaning can also be active cleaning, and can also be cleaned every time the filter layer 3 is expanded or retracted. Because the intervals between the connecting ring 36 and the filter assembly 6 are hollow, the hollow positions from top to bottom of the device can be used for dust to fall into The inside of the collection frame 11 is cleaned centrally, and the filter assembly 6 is installed by a fixed rod 61. There is space for the fixed rod 61 to move at the bottom of the connecting ring 36 at the bottom of the filter layer 3 and the bottom of the scraper 37 and the electric telescopic plate 38, which can avoid movement interference due to the existence of the fixed rod 61 during the rotation of the filter layer 3. The fixed rod 61 can ensure that each layer of the filter assembly 6 is fixedly installed on a plane and maintains stability. During normal use, the bottom of the electric telescopic plate 38 and the scraper 37 are blocked by the elastic rubber strip 310 to prevent air and dust from flowing out.

[0038] When the device is used, based on CIM technology, the detection of environmental wind direction and air pollution level in the urban system is used and transmitted to the device. The device is set on the roof according to demand. When the environment is good, the dust particles in the air can be purified and filtered by natural wind. The wind direction is determined by the wind vane 24, and the angle sensor 25 detects the angle of deviation of the wind vane 24, and transmits the signal to the drive motor 21. The drive motor 21 drives the drive gear 22 to rotate and mesh with the gear ring 23, so that the vertical plate 51 drives all the filter layers 3 to rotate, and the drive shaft 41 and the air outlet pipe 12 also rotate synchronously, so that the position of the air inlet 31 corresponds to the natural wind, and the internal motor of the vertical shaft drives the rotating plate 53 to rotate, thereby connecting the frame 5 4 pulls the bottom filter layer 3 to rotate. Because each group of filter layers 3 is connected by a pull rope 52, the remaining groups will also be pulled one by one and gradually unfolded into a state of six equal parts, so that the air inlet 31 faces all around. When storing, through the push of the connecting frame 54 and the obstruction of the vertical plate 51, all the filter layers 3 that are rotated to open will gradually gather on one side of the vertical plate 51 to form a vertical row, so that the vertical row of air inlets 31 can correspond to the wind direction of the ambient wind. The fan 33 in the air inlet 31 is driven by the ambient wind to rotate, and the air is introduced into the filter screen for processing. When the air quality is poor, the transmission component 4 and the drive component 5 rotate the filter layer 3 to open it, and automatically absorb and filter the particles in the surrounding air, so as to achieve fast and efficient The air purification treatment, two connecting rings 36, scraper 37 and electric telescopic plate 38 form a channel, which can allow the air sent in by the air inlet 31 to pass through the three-layer filter and then be sent out from the air outlet 32. In this structure, first, the bottom part is the bottom telescopic plate 39, and the extended end is connected to the extended end of the electric telescopic plate 38, so when the electric telescopic plate 38 is retracted, it will also drive the bottom telescopic plate 39 to retract. At this time, the side and bottom of the channel close to the filter are opened, and the connecting ring 36 is rotated around the filter assembly 6 with the driving assembly 5 or the transmission assembly 4. The scraper 37 cleans the surface of the filter, scrapes off the adsorbed dust particles, and drops them from the bottom to the collection box. This part of the cleaning can also be active cleaning, or it can be done at each filtering layer. 3 is cleaned when it is expanded or retracted. Because the intervals between the connecting ring 36 and the filter assembly 6 are hollow, the hollow positions from top to bottom of the device can allow dust to fall into the collection frame 11 for centralized cleaning. The filter assembly 6 is installed through the fixing rod 61. At the bottom of the connecting ring 36 at the bottom of the filter layer 3 and the bottom of the scraper 37 and the electric telescopic plate 38, there is space for the fixing rod 61 to move, which can avoid movement interference due to the existence of the fixing rod 61 during the rotation of the filter layer 3. The fixing rod 61 can ensure that each layer of the filter assembly 6 is fixedly installed on a plane and maintains stability. In normal use, the bottom of the electric telescopic plate 38 and the scraper 37 are blocked by the elastic rubber strip 310 to prevent air and dust from flowing out.
