[0016] 1. The rotation of the rotating rod is driven by the motor. The rotation of the rotating rod drives the rotation of the first sprocket. Through the cooperation between the first sprocket and the first chain, the rotation of multiple groups of rotating rods is driven. The rotation of the rotating rods drives the rotation of multiple groups of fan blades. The rotation of the fan blades can cause a negative pressure to be generated inside the box body and the connecting pipe. Then, through the connecting frame, the cat hair on the ground is sucked into the box body. At this time, the first filter screen, the second filter screen, and the mesh plate filter the cat hair, thereby achieving the effect of quickly sucking the cat hair, dust, etc. on the ground of the cat house in the laboratory. Furthermore, it can quickly and thoroughly remove pollutants such as cat hair and dust on the ground, reducing the cleaning time and labor costs. Compared with the problems of low efficiency, large pollution, and high labor intensity existing in the manual cleaning method in the prior art, it provides a more efficient, convenient, and safe solution for the cleaning work of the experimental cat house. When the wheels rotate in contact with the ground, the rotation of the transmission rod drives the rotation of the second sprocket. Through the cooperation between the second sprocket, the third sprocket, and the second chain, the rotation of the rotating rod is driven. The rotation of the rotating rod drives the rotation of the first rotating tooth. The rotation of the second rotating tooth drives the rotation of the reciprocating lead screw. The movement of the moving plate drives the two brush plates to move up and down reciprocally, thereby using the brush plates to clear the blockage of the first filter screen and the second filter screen. Furthermore, it can effectively avoid the phenomenon that the first filter screen and the second filter screen are blocked by cat hair impurities, resulting in poor gas circulation, making the device have the effect of semi-automatic cleaning and avoiding the effect that the staff frequently cleans and maintains the filter.

[0017] 2. Since the tops of the first filter screen and the second filter screen are fixedly connected to the mounting plate, when the staff inserts the mounting plate into the top of the collection box, at this time, both the first filter screen and the second filter screen are placed inside the collection box. At this time, the mounting plate is inserted by multiple inserting rods. At this time, the limiting box slides outside the inserting rods. By the staff pressing the sliding rod, the sliding plate is driven to slide inside the limiting box. At this time, the sliding plate drives multiple extrusion rods to slide inside the fixed tube.

[0030] Working principle: Before using this experimental cat kennel cleaning device, it is necessary to first check the overall situation of the device to determine that it can work normally. According to Figure 1 - Figure 6As shown in the figure, the staff moves the device to the target area, and then starts the motor 209. At this time, the motor 209 drives the rotation of the rotating rod 205. The rotation of the rotating rod 205 drives the rotation of the first sprocket 207. Through the cooperation between the first sprocket 207 and the first chain 208, the rotation of multiple groups of rotating rods 205 is driven. The rotation of the rotating rod 205 drives the rotation of multiple groups of fan blades 206. The rotation of the fan blades 206 drives the generation of negative pressure inside the box body 201 and the connecting pipe 203. Then, the ground cat hair is sucked into the box body 201 through the connecting frame 202. At this time, the cat hair and air enter the collection box 101 along the air pipe 204. At this time, the first filter screen 210, the second filter screen 211 and the mesh plate 102 filter the cat hair, so as to quickly suck the cat hair and dust on the ground of the cat house in the laboratory, and then quickly and thoroughly remove pollutants such as cat hair and dust on the ground, reduce the cleaning time and labor cost. Compared with the problems of low efficiency, large pollution and high labor intensity existing in the manual cleaning method in the prior art, it provides a more efficient, convenient and safe solution for the cleaning work of the experimental cat house. When the staff uses the device to move and clean the ground, the wheels 214 contact the ground and rotate. The rotation of the wheels 214 drives the rotation of the transmission rod 213. The rotation of the transmission rod 213 drives the rotation of the second sprocket 215. Through the cooperation between the second sprocket 215, the third sprocket 218 and the second chain 219, the rotation of the rotating rod 217 is driven. The rotation of the rotating rod 217 drives the rotation of the first rotating tooth 220. The rotation of the first rotating tooth 220 drives the rotation of the second rotating tooth 222. The rotation of the second rotating tooth 222 drives the rotation of the reciprocating screw rod 221. The rotation of the reciprocating screw rod 221 drives the moving plate 223 to move. The movement of the moving plate 223 drives the two brush plates 224 to move up and down reciprocally, so as to clean and block the first filter screen 210 and the second filter screen 211 by using the brush plates 224. Furthermore, it can effectively avoid the phenomenon that the first filter screen 210 and the second filter screen 211 are blocked by cat hair impurities, resulting in poor gas circulation, making the device have the effect of semi-automatic cleaning, avoiding the effect that the staff frequently cleans and maintains the filter, and bringing convenience to the staff when using;

[0031] Since the tops of the first filter screen 210 and the second filter screen 211 are fixedly connected to the mounting plate 301, when the staff inserts the mounting plate 301 into the top of the collection box 101, at this time, both the first filter screen 210 and the second filter screen 211 are placed inside the collection box 101. At this time, the mounting plate 301 is inserted by multiple insertion rods 302. At this time, the limit box 303 slides outside the insertion rods 302. By the staff pressing the sliding rod 304, the sliding plate 305 is driven to slide inside the limit box 303. At this time, the sliding plate 305 drives multiple extrusion rods 308 to slide inside the fixed tube 306. At this time, the contraction spring 307 contracts. By releasing the sliding rod 304, and then through the reset property of the contraction spring 307, multiple insertion blocks 309 can be inserted into the insertion rods 302, and then the effect of quickly fixing and limiting the mounting plate 301 can be achieved, and then the effect of quickly installing and disassembling the first filter screen 210 and the second filter screen 211 can be achieved, so as to facilitate the staff to inspect and repair the first filter screen 210 and the second filter screen 211 subsequently, greatly improving the daily maintenance efficiency of the device, bringing convenience to the staff during use. Through the design of the handle 310, it is convenient for the staff to operate the mounting plate 301.
