[0040] The dust removal mechanism includes a movable plate 301 that is slidably connected to the side of the back plate 1 away from the back frame 13, a fan 303 is fixedly connected to the bottom of the back plate 1 away from the back frame 13, a hose 302 is fixedly connected between the movable plate 301 and the fan 303, both ends of the movable plate 301 are rotatably connected to a runner 304, the interior of the movable plate 301 is rotatably connected to an impeller 305, the bottom of the movable plate 301 is rotatably connected to a wiping roller 306, a belt 307 is transmitted between the impeller 305 and the wiping roller 306, and a fixed connection is provided between the runner 304 and the movable plate 301. It is connected to a coil spring 308, and both ends of the movable plate 301 are rotatably connected to rollers 315. A storage tube 313 is placed inside the movable plate 301, and the interior of the storage tube 313 is slidably connected to a connecting rod 309. Both ends of the connecting rod 309 are fixedly connected to a closing plate 310, and a return spring 311 is fixedly connected between one of the closing plates 310 and the storage tube 313. The inner wall of the storage tube 313 is fixedly connected to a filter screen 312, and the outside of the two rotating wheels 304 are fixedly connected to rubber rings 314. The storage tube 313 is fixedly connected between the two side plates 12.

[0041] Furthermore, the driving mechanism includes a motor 201 fixedly connected to the side of the back plate 1 close to the back frame 13, and two pairs of rotating disks 202 are rotatably connected to the side of the back plate 1 close to the back frame 13, wherein one pair of rotating disks 202 is fixedly connected to the output shaft of the motor 201, and a conveyor belt 203 is transmission-connected between the two pairs of rotating disks 202, and a baffle 204 is fixedly connected to the outside of the conveyor belt 203, and a push plate 205 is rotatably connected to the outside of the conveyor belt 203, and a support spring 206 is fixedly connected between the push plate 205 and the outer wall of the rotating disk 202;

[0042] The supporting mechanism includes a partition 401 fixedly connected between the two side plates 12, the bottom of the partition 401 is slidably connected to the support plate 402, the outer side of the support plate 402 is rotatably connected to the limiting tube 403, the inner side of the limiting tube 403 is slidably connected to the support rod 404, and an ejection spring 405 is fixedly connected between the bottom end of the support rod 404 and the inner wall of the limiting tube 403.

[0043] When the handle 314 is in the closed position, the handle 316 is in the closed position, and the push rod 305 is in the closed position, so that the handle 314 can be turned off.

[0044] Furthermore, the interior of the movable plate 301 is set as a cavity, and an air inlet connected to the cavity is opened at the bottom of the movable plate 301. The bottom of the wiping roller 306 is in contact with the top surface of the partition 401. When the device is sucking dust, the airflow will drive the wiping roller 306 to rotate continuously to wipe the top surface of the partition 401, so that the dust can be separated from the surface of the partition 401 and be sucked away more smoothly along with the air, thereby further improving the dust removal effect of the device.

[0045] Furthermore, the baffle 204 is fitted with the side of the push plate 205 away from the support spring 206, and a strip groove is provided on the side of the back plate 1 close to the rotating disk 202. The push plate 205 is slidably connected to the inside of the strip groove, and the end of the movable plate 301 away from the storage tube 313 extends to the inside of the strip groove. After the push plate 205 enters the strip groove of the back plate 1 and contacts the movable plate 301, the push plate 205 continues to move to push the movable plate 301 and drive the movable plate 301 to slide between the back plate 1 and the limit plate 316, so that the movable plate 301 moves on the partition 401 to remove dust at different positions, thereby improving the dust removal effect.

[0046] Furthermore, the rollers 315 located on both sides of the movable plate 301 are in contact with the side close to the back plate 1 and the limit plate 316 respectively. During the movement of the movable plate 301, the rollers 315 will roll on the surface of the side close to the limit plate 316 and the back plate 1, reducing the friction between the movable plate 301 and the limit plate 316 and the back plate 1, thereby facilitating the movement of the movable plate 301. A cavity is provided inside the back plate 1 for the hose 302 to move.

[0047] Furthermore, a tooth groove is provided at the bottom of the partition 401, and the top end of the support rod 404 is embedded in the inside of the tooth groove. There are four partitions 401, and the four partitions 401 are arranged vertically and equidistantly. There are three support plates 402, and the three support plates 402 are respectively located between adjacent partitions 401. After the top end of the support rod 404 is embedded in the tooth groove on the bottom surface of the partition 401, the limiting tube 403 and the support rod 404 can no longer rotate and can support the support plate 402, so that the support plate 402 can stably support the books and prevent the books from falling over.

[0048] Furthermore, the storage cylinder 313 is connected to the internal cavity of the movable plate 301, and the two closing plates 310 are respectively embedded in the openings at both ends of the storage cylinder 313 and sealed with the openings of the storage cylinder 313. During dust removal, the airflow can push the closing plates 310 and compress the reset spring 311, so that the opening of the storage cylinder 313 is opened for air to pass through. After the dust removal is completed, the stretching elastic force of the reset spring 311 drives the closing plates 310 to reset, so that the two closing plates 310 re-close the two openings of the storage cylinder 313, thereby avoiding dust leakage when the storage cylinder 313 is manually removed from the movable plate 301, thereby facilitating the cleaning of the dust in the storage cylinder 313.

[0049] Working principle: In the initial state, the support spring 206 is in a compressed state. The extension force of the support spring 206 supports the push plate 205, so that the push plate 205 fits the baffle 204. At this time, the push plate 205 is perpendicular to the conveyor belt 203, the top of the support rod 404 contacts the bottom surface of the partition 401, and the ejection spring 405 is in a compressed state.

[0050] After placing the book, in order to prevent the book from falling over, the book is placed close to the side plate 12 of the support plate 402, and then the support plate 402 is manually pushed to slide the support plate 402 toward the book until the support plate 402 contacts the book. At this time, the book is clamped in a vertical state by the side plate 12 and the support plate 402, and the support rod 404 is manually pressed and the ejection spring 405 is kept in a compressed state, so that the support rod 404 and the limiting tube 403 cannot move relative to each other. Then the limiting tube 403 is manually rotated. When the limiting tube 403 moves away from the support plate 40 2, the support rod 404 is gradually loosened manually, so that the extension force of the ejection spring 405 drives the support rod 404 to extend from the limiting tube 403 until the top end of the support rod 404 is embedded in the tooth groove on the side of the partition 401 close to the support plate 402. Under the positioning of the tooth groove, the limiting tube 403 and the support rod 404 can no longer rotate, and the ejection spring 405 is still in a compressed state. Under the support of the limiting tube 403 and the support rod 404, the support plate 402 can stably support the books, preventing the books from falling over, making it easier to find and take out the books.

[0051] When dust falls on the upper surface of the partition 401, the motor 201 and the fan 303 are manually started, and the output shaft of the motor 201 rotates to drive the rotating disk 202 fixed thereto to rotate. Since the two rotating disks 202 are connected by a conveyor belt 203, the rotation of the above-mentioned rotating disk 202 can drive the rotating disk 202 to circulate outside the two conveyor belts 203. The circulatory rotation of the conveyor belt 203 drives the push plate 205 to move. After the push plate 205 enters the strip groove of the back plate 1 and contacts the movable plate 301, the push plate 205 continues to move to push the movable plate 301 and drive the movable plate 301 to slide between the back plate 1 and the limit plate 316. During this process, the roller 315 rolls on the surface of the side close to the limit plate 316 and the back plate 1, lowering the movable plate 301 and the limit plate 3 The friction between 16 and the back panel 1 facilitates the movement of the movable panel 301. The fan 303 extracts the air in the cavity of the movable panel 301 through the hose 302, so that a negative pressure is generated in the cavity of the movable panel 301. Under the push of the negative pressure, the two closing plates 310 are pushed, and the return spring 311 is compressed. At this time, the two openings of the storage cylinder 313 are opened, and the air in the cavity of the movable panel 301 can be transported to the outside through the storage cylinder 313 and the hose 302. The dust on the surface of the partition 401 is sucked into the movable panel 301 along with the air under the action of the negative pressure, and finally filtered by the filter 312 and retained in the storage cylinder 313. Through this design, the surface of the partition 401 can be automatically cleaned without manual regular cleaning, saving manpower and facilitating the storage of books.

[0052] Since the bottoms of the two rubber rings 314 are respectively in contact with the inner wall of the back plate 1 and the inner wall of the limit plate 316, the two wheels 304 will roll on the inner walls of the back plate 1 and the limit plate 316 during the movement of the movable plate 301 under the action of the friction between the rubber rings 314, the back plate 1 and the limit plate 316. Since the movable plate 301 does not rotate, the rolling of the wheels 304 will rotate relative to the movable plate 301. The rotation of the wheels 304 will tighten the coil spring 308. When the movable plate 301 moves to contact the support plate 402, the movable plate 301 cannot continue to slide under the obstruction of the support plate 402, but the conveyor belt 203 still drives the push plate 205 to circulate, so the movable plate 301 no longer moves the reverse force applied to the push plate 205 The force applied will cause the push plate 205 to deflect in the direction away from the baffle 204, and the support spring 206 is compressed. After the push plate 205 is deflected, it will cross the movable plate 301 and will no longer push the movable plate 301. At this time, the relaxation of the coil spring 308 drives the rotating wheel 304 and the rubber ring 314 to rotate in the opposite direction, so that the rotating wheel 304 rolls in the opposite direction on the inner wall of the back plate 1 and the limit plate 316, driving the movable plate 301 to move in the opposite direction until the movable plate 301 is reset, so that the dust removal process can be carried out again. Through this design, the empty part on the partition 401 can be dust-removed when books are placed on the partition 401, and the number of books placed will not change the dust removal effect, so that the device can meet a wider range of usage needs, thereby improving the applicability of the device;

[0053] After passing through the storage cylinder 313, the air will pass through the impeller 305. The flow of air will drive the impeller 305 to rotate, and the wiping roller 306 will be driven by the belt 307 to rotate. Since the bottom of the wiping roller 306 is in contact with the top surface of the partition 401, the wiping roller 306 rotates continuously to wipe the top surface of the partition 401 while the device is sucking dust, so that the dust can be separated from the surface of the partition 401 and be sucked away more smoothly along with the air, thereby further improving the dust removal effect of the device and facilitating practical use. After the fan 303 stops running, the closing plate 310 is no longer pushed by the air flow. At this time, the stretching elastic force of the reset spring 311 drives the closing plate 310 to reset, so that the two closed plates The plate 310 reseals the two openings of the storage tube 313 to prevent dust from leaking out when the storage tube 313 is manually taken out from the movable plate 301, thereby facilitating the cleaning of the dust in the storage tube 313 and further improving the use effect of the device. After the storage tube 313 collects dust, the storage tube 313 is manually taken out from the movable plate 301, and then the closing plate 310 fixed to the return spring 311 is manually pressed. The closing plate 310 retracts into the storage tube 313 under pressure and compresses the return spring 311. At this time, the opening of the storage tube 313 is opened, and the dust inside the storage tube 313 can be directly poured out manually to remove the dust.
