The main controller is respectively controlled and connected with each switch, the motor 162 in the external door drive 107, the motor 162 in the internal door drive 108, the fan blade motor 7 and the pressure sensor 14.

[0078] The working principle of the present invention is as follows: the device is arranged at the entrance of the clean area of ​​the factory, the outer door 105 faces the side away from the clean area, and the inner door 106 faces the clean area.

[0079] When the device is in the initial state, the return spring 1303 is in a naturally extended state, and there is a distance between the pressure sensor 14 and the bottom of the upper plate 1301, and the two are not in contact. The outer door 105 and the inner door 106 are both in a closed state, the reel 163 is in an unwinding state, and the lifting rope 164 is in a released and extended state.

[0080] When a person or an object walks onto the pre-channel 13 next to the outer door 105, the return spring 1303 is compressed, driving the upper plate 1301 to move downward, so that the limit pin 1305 is inserted into the limit hole at the top of the guide column 1304, and the distance between the upper plate 1301 and the lower plate 1302 is shortened. The pressure sensor 14 senses the force of the person or object after contacting the bottom of the upper plate 1301, and the pressure sensor 14 transmits the information to the main controller. The main controller controls the motor 162 to start, and the motor 162 drives the synchronous shaft 161 to rotate. The synchronous shaft 161 also drives the reel 163 installed at its left and right ends to rotate and start to reel in the lifting rope 164. As the length of the lifting rope 164 continues to shorten, under the action of the tension generated by the lifting rope 164, in addition to the hinge shaft 2012 of the door panel 201 located on the top layer, it starts to rotate in the mounting seat on the wind corridor 101. Outside, each hinge shaft 2012 begins to rotate in the ring 2013, so that each door panel 201 gradually rotates from a state biased to a horizontal state, and the sealing layer 202 is also folded as the door panels 201 rotate, and the outer door 105 gradually shrinks upward. When the outer door 105 is completely shrunk, people or objects can enter the interior of the wind corridor 101, stand on the manhole plate 1101, press the "outer door open or close" button, and close the outer door 105. The motor 162 starts to drive the synchronous shaft 161 to reverse, and the synchronous shaft 161 drives the two winders 163 to reverse and start unwinding the lifting rope 164. As the length of the lifting rope 164 continues to increase, the door panels 201 begin to rotate with each other under the action of gravity, and gradually rotate from a state biased to a state biased to a vertical state, until the outer door 105 is completely unfolded downward, and the sealing layer 202 is unfolded from a folded shape to a vertical sheet.

[0081] When the "air shower on or off" button is pressed, the main controller receives the switch signal and controls the fan motor 7 to start, driving the fan blades 6 to rotate. The wind generated by the rotation of the fan blades 6 is transmitted along the air duct 4 through the air pipe 5 to each air shower head 3 and blown out from the air outlet 304 to clean people or objects and reduce dust on people or objects. The air outlet gear of the fan motor 7 can be adjusted by the three buttons of "weak wind", "medium wind" and "strong wind". At the same time as the fan motor 7 is started, the large bevel gear 151 on the output shaft of the fan motor 7 starts to rotate, driving the first bevel gears 153 on the left and right sides thereof to rotate. The first bevel gear 153 drives the second bevel gear 154 to rotate through the primary transmission shaft 152, and the second bevel gear 154 drives the third bevel gear 156 to rotate. The third bevel gear 156 drives the fourth bevel gear 157 to rotate through the secondary transmission shaft 155. The fifth bevel gear 158 drives the rotating shaft 302 to rotate, and the rotating shaft 302 drives the pulleys 303 at both ends thereof to rotate, and each pulley 303 drives the air shower heads 3 in the first row of one column of the air shower heads 3 to rotate through the belt 301, and the air shower heads 3 in the first row drive the air shower heads 3 in the second row to rotate through another belt 301, and the air shower heads 3 in the second row drive the air shower heads 3 in the third row to rotate through another belt 301. Because each air outlet 304 is provided on the side wall of a part of the hollow capsule-shaped air shower head 3 located in the inner layer frame 103, as each air shower head 3 rotates, the direction of each air outlet 304 will change, so as to realize multi-angle blowing of each air shower head 3, enhance the blowing coverage angle, and try to ensure full coverage of the cleaning personnel or objects, and the blown dust will fall into the groove 1102 through the holes on the standing manhole plate 1101.

[0082] While the fan blades 6 are rotating, the air in the cylindrical tube 802 above the fan blades 6 will also be fanned out after being driven by the fan blades 6 to rotate, forming a negative pressure state and generating suction. Under the action of the suction, the dust in the groove 1102 will pass through the holes on the longitudinal reinforcing ribs 1104 and enter the corresponding ash tubes 12 from the ash holes 1105, and then enter the shell 804 from the ash tube 12 along the connecting pipe 806, and enter the cylindrical tube 802 after being guided by multiple guide blades 805 to rotate. Under the action of the rotating centrifugal force, most of the dust will enter the dust shell 1001 and then enter the box 1002 from the square hole 1003. Because the dust shell 1001 and the box 1002 are both made of transparent materials, when the device stops working, after observing that the amount of dust contained in the box 1002 reaches a certain value, the box 1002 can be slid out from the opening of the dust shell 1001, and the dust in the box 1002 can be poured out and then installed back. A small part of the dust that fails to enter the dust shell 1001 in time will be entangled on the tubular filter 803, and the multiple fan-blade scrapers 901 will rotate under the action of wind while the fan blades 6 rotate, and scrape the dust on the outer surface of the tubular filter 803. When the multiple fan-blade scrapers 901 rotate, they will drive the multiple rollers 903 to slide in the annular groove 8021 through the circular ring 902.

[0083] After dust removal is completed, press the "air shower open or close" button. After receiving the switch signal, the main controller controls the fan motor 7 to turn off. As the fan motor 7 stops rotating, the fan blades 6 stop rotating, and the air duct 4 no longer supplies air through the air pipe 5. At the same time, as the large bevel gear 151 stops rotating, the pulley 303 also stops rotating, so that all the air shower heads 3 stop rotating. The cylindrical tube 802 no longer generates suction and no longer absorbs dust. At the same time, the multiple fan-shaped scrapers 901 also stop rotating. Press the "inner door open or close" button again to open the inner door 106. After receiving the switch signal, the main controller controls the motor 162 to rotate, thereby driving the reel 163 to rotate and start winding through the synchronous shaft 161. Each door panel 201 starts to rotate, and the inner door 106 retracts upward. The working principle of each component is the same as that of the outer door 105 mentioned above. When a person or object walks out of the wind corridor 101 and onto the pre-channel 13 next to the inner door 106, the reset spring 1303 is compressed, driving the upper plate 1301 to move downward, and the pressure sensor 14 contacts the bottom of the upper plate 1301 and senses the force of the person or object. The pressure sensor 14 transmits the information to the main controller, and the main controller controls the motor 162 to start, driving the reel 163 to rotate through the synchronous shaft 161 to start unwinding, so that the inner door 106 unfolds downward and returns to the closed state.

[0084] It should be noted that the present invention is not limited to the specific structures shown in the drawings in the above-mentioned embodiments, and various changes can be made thereto within the knowledge scope of ordinary technicians in this field.
