Example Embodiment

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0018] The present invention provides figure 1 , figure 2 with image 3 An adjustable dust-absorbing blackboard eraser shown includes a blackboard eraser main body 10, the two sides of the blackboard eraser main body 10 are provided with a turning bearing 6 and both sides of the turning bearing 6 are provided with a splicing bearing surface 5. The upper surface of the splicing receiving surface 5 is provided with a magnetic suction plate 1, and the magnetic suction plate 1 is provided with blackboard wipes 3 on both sides, the bottom of the blackboard wipe 3 is provided with a dust adsorption cavity 2, and the bottom of the dust adsorption cavity 2 is provided There is a drive shaft wheel 4, the center of the drive shaft wheel 4 is provided with a drive device 7, and the bottom of the drive device 7 is provided with a dust collection chamber 9, which includes a dust collection inner bin 901, a fixed buckle 902, The baffle block 903, the dust collecting inner core 904, the dust collecting inner bin 901 is arranged in the center of the dust collecting chamber 9, the fixed buckle 902 is arranged on the upper surface of the dust collecting inner bin 901, the baffle frame 903 Set at the bottom of the fixed buckle 902, and the dust collection inner core 904 is set at the bottom of the baffle frame 903;

[0019] The center of the dust collection chamber 9 is provided with a rotating shaft roller 8, the bottom of the rotating shaft roller 8 is provided with a coupling rod 10, both sides of the coupling rod 10 are provided with suction buckles 11, the suction buckle 11 right A supporting crossbar 12 is provided on the side. The bottom of the supporting crossbar 12 is provided with a folding wipe block 14, the bottom of the folding wipe block 14 is provided with an absorbent sponge 13, and the bottom of the absorbent sponge 13 is provided with a telescopic handheld rod 15 The telescopic handheld rod 15 includes a handheld rod body 1501, a fixed threaded ring 1502, a telescopic sleeve 1503, and a non-slip hand grip 1504. The handheld rod body 1501 is arranged at the center of the telescopic handheld rod 15. The fixed threaded ring 1502 is arranged at the center of the handle body 1501, the telescopic sleeve 1503 is arranged at the bottom of the fixed threaded ring 1502, and the non-slip hand grip 1504 is arranged at the bottom of the telescopic sleeve 1503.

[0020] Specifically, the driving device 7 includes a driving axle wheel 4 and a rotating axle roller 8, the driving axle wheels 4 are arranged on both sides of the driving device 7, and the rotating axle roller 8 is arranged on the bottom of the driving axle wheel 4.

[0021] Specifically, the upper surface of the telescopic hand-held rod 15 is provided with threads, and the telescopic hand-held rod 15 and the blackboard eraser main body 10 are rotationally connected by threads.

[0022] Specifically, there are two folding wipe blocks 14, and the two folding wipe blocks 14 are arranged symmetrically on both sides of the blackboard eraser main body 10 respectively.

[0023] Specifically, the center of the driving device 7 is circular, and its center coincides with the center of the driving shaft wheel 4.

[0024] Specifically, the foldable eraser block 14 and the blackboard eraser main body 10 are connected and fixed by an adsorption buckle 11.

[0025] Working principle: In the process of using this adjustable vacuum blackboard eraser, first connect the parts of the blackboard eraser body 10, hold the telescopic handle 15 and adjust its height, and wipe the blackboard eraser 3 close to the blackboard. , The drive device 7 drives the drive shaft wheel 4 and the rotating shaft roller 8 to rotate to reduce the internal air pressure, so that the dust enters the dust collection chamber 9 through the dust adsorption chamber 2, and the adsorption buckle 11 is opened, and the folding wipe block 14 is turned over The shaft 6 is folded and fixed. The splicing bearing surface 5 is parallel to the main wiper surface. The absorbent sponge 13 wipes the blackboard after absorbing water to increase cleanliness. The support bar 12 is used to support the horizontal balance of the folding wiper block 14, and the connecting rod 10 The hand-held telescopic hand lever 15 and the blackboard eraser main body 10 are connected.
