The working principle is as follows: when the device needs to be cleaned, an operator controls the motor to be started, the motor is started to drive the rotating shaft 21 to rotate, the rotating shaft 21 drives the first bevel gear 241 to rotate, the first bevel gear 241 rotates to drive the second bevel gear 242 to rotate, the second bevel gear 242 rotates to drive the screw rod 243 to rotate, the screw rod 243 rotates to drive the moving block 244 to move, the moving block 244 moves to drive the cleaning brush 22 to move, the rotating shaft 21 also drives the second pulley 233 to rotate, under the action of the transmission belt 234, the second pulley 233 rotates to drive the first pulley 232 to rotate, the first pulley 232 rotates to drive the rotating rod 231 to rotate, the rotating rod 231 rotates to drive the second gear 237 to rotate, the second gear 237 rotates to drive the first gear 236 to rotate, the first gear 236 rotates to drive the sliding plate 238 to rotate, the sliding plate 238 rotates to drive the linkage rod 239 to rotate, the linkage rod 239 rotates to drive the cleaning brush 22 to rotate, so that the cleaning brush 22 can also rotate in the moving process, therefore, not only can the side surface of the device be cleaned, but also the bottom of the device can be cleaned, so that the cleaning effect and the cleaning efficiency of the device are higher, and the contact time of the cleaning brush 22 and the inner wall of the device is prolonged through the compression of the first spring 25, so that the inside of the device can be better cleaned;

under the action of the lead screw 243, the sliding plate 238 will also move downwards in the rotating process, the sliding plate 238 moves downwards, at the moment, the moving block 244 loses support and moves downwards to reduce the pressure at the top of the air storage bag 331, under the action of the restoring force of the air storage bag 331, suction force is generated inside the air storage bag 331 to drive the air inlet plate 337 to rotate, the air inlet plate 337 rotates to open the air inlet pipe 3310, under the action of the suction force of the air storage bag 331, suction force is generated at the bottom of the air inlet cavity 339 to absorb harmful gas inside the device, the harmful gas enters the air inlet pipe 3310 through the air inlet cavity 339 and then enters the air storage bag 331 through the air inlet pipe 3310, so that the harmful gas inside the device can be absorbed, when the sliding plate 238 moves upwards under the action of the lead screw 243, the moving block 244 moves upwards along with the movement of the sliding plate 238, and the moving block 244 moves to drive one end of the pull rope 322 to move, so that the reel 321 rotates, the reel 321 rotates to drive the pressing rod 324 to rotate, the pressing rod 324 rotates to drive the round rod 325 to rotate, the round rod 325 rotates to drive the pressing plate 326 to move downwards, the air storage bag 331 is compressed in the downward movement process of the pressing plate 326, the internal pressure of the air storage bag 331 is increased and the air exhaust plate 334 is extruded in the compression process of the air storage bag 331, so that the air exhaust plate 334 moves towards two sides, the exhaust pipe 335 is opened, at the moment, the gas in the upper half part of the interior of the air storage bag 331 starts to move downwards through the adsorption cotton block 332 under the action of the internal pressure, when the harmful gas passes through the adsorption cotton block 332, the harmful gas is neutralized with the chemical agent in the adsorption cotton block 332, the purified gas enters the exhaust pipe 335 and enters the exhaust cavity 336 from the exhaust pipe 335, and is finally exhausted from the exhaust cavity 336 to the interior of the device, so that the harmful gas in the interior of the device can be removed, the pressure inside the device can be kept in a normal state, which is beneficial to the normal operation of the cleaning device.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
