Preferably, the top end of the fixed sleeve 32 is a square plugboard 321, and the inner side wall of the eraser connecting seat 43 is a long groove 431 corresponding to the shape of the plugboard 321. The top end of the fixed sleeve 32 stretches into and is stuck in the long groove 431 of the eraser connecting seat 43 and resists against the eraser adjusting clip 44, so that when the motor 13 rotates, it can drive the first gear transmission member 3 and the eraser connecting seat 43 to rotate, thereby driving the eraser adjusting clip 44 and the eraser 12 to rotate.

[0042] The dust collection mechanism 2 is provided with a second gear transmission member 5, which is located in the installation cavity 11. The second gear transmission member 5 includes a second gear 51 and a connecting rod 52 integrally arranged in the middle of the second gear 51.

The middle part of the corresponding second partition plate 111 is provided with a notch for the connecting rod 52 to extend into;

[0043] A gear guide rod 6 is also fixed in the installation cavity 11. The gear guide rod 6 is a straight rod with gears at both ends. Specifically, the two ends of the gear guide rod 6 are respectively provided with a first guide gear 61 meshing with the first gear 31 and a second guide gear 62 meshing with the second gear 51. A control rod 15 for controlling the engagement or disengagement of the first gear 31 and the first guide gear 61 is also provided in the installation cavity 11. The control rod 15 can drive the fixed sleeve 32 to move back and forth on the output end of the motor 13, so that the first gear 31 is engaged with or disengaged from the first guide gear 61. Specifically, a limiting step 311 is provided near the open end of the fixed sleeve 32, and one end of the control rod 15 has a collar 151. 151 is sleeved between the limiting step 311 and the first gear 31. The other end of the control rod 15 is a sliding end 152. The sliding end 152 extends from the mounting cavity 11 and is located on the housing 1. Accordingly, a slide groove 16 is provided on the housing 1 for the sliding end 152 of the control rod 15 to be placed. When the sliding end 152 is located at one end of the slide groove 16 close to the eraser 12, the inserting plate 321 passes through the middle of the first partition and is located in the long groove 431. The first gear transmission member 3 is in the disengaged position, that is, the first gear 31 is disengaged from the first guide gear 61. When the sliding end 152 is located at the other end of the slide groove 16, the first gear transmission member 3 is in the meshing position, that is, the first gear 31 is meshed with the first guide gear 61.

[0044] It should be noted that the distance that the sliding end 152 can slide in the slide groove 16 needs to be greater than or equal to the thickness of the first gear 31, and the depth of the long groove 431 needs to be adapted to the thickness of the first gear 31, so that when the sliding end 152 moves to the other end of the slide groove 16, the plug plate 321 can be disengaged from the long groove 431, and the first gear 31 can engage with the first guide gear 61. There needs to be space between the first gear 31 and the first partition 121 for the first gear 31 to move, so that the plug plate 321 can extend into or out of the long groove 431; the shell 1 is also provided with a switch 17 for controlling the opening and closing of the motor 13, and the switch 17 and the motor 13 can be connected by a conventional electrical connection method, such as through a wire connection. Preferably, the shell 1 is also provided with a USB charging port for continuous use.

[0045] When the electric eraser function is used normally, the sliding end 152 is located at one end of the slide 16 near the eraser 12. At this time, the first gear 31 and the first guide gear 61 are disengaged, and the plug 321 of the fixed sleeve 32 is located in the long groove 431 and abuts against the eraser adjustment clip 44. Press the switch 17 to start the motor 13, and the motor 13 drives the first gear transmission member 3 to rotate, and the fixed sleeve 32 drives the eraser connecting seat 43 and the eraser adjustment clip 44 to rotate, thereby driving the eraser 12 to rotate for wiping. When it is necessary to clean the debris after wiping, move the sliding end 152 to the slide 1 6, the control rod 15 drives the first gear transmission member 3 away from the eraser adjustment clamp 44, that is, the insert plate 321 of the fixed sleeve 32 leaves the long slot 431. At this time, the first gear 31 moves to the position of the gear guide rod 6 and engages with the first guide gear 61. The switch 17 is pressed to start the motor 13, and the motor 13 drives the first gear transmission member 3 and the first gear 31 to rotate. The first gear 31 drives the gear guide rod 6 and the second guide gear 62 to rotate, thereby driving the second gear transmission member 5 and the centrifugal impeller 23 to rotate. The rotation of the centrifugal impeller 23 generates suction to suck debris into the dust collection chamber.

[0046] The electric eraser of the present invention is provided with a first gear transmission member 3, a second gear transmission member 5, a gear guide rod 6 and a control rod 15, and the sliding end 152 of the control rod 15 is provided on the housing 1. In this way, the effect of driving the eraser 12 or the dust collection mechanism 2 to operate can be achieved by providing a driving mechanism. Compared with the prior art, the volume of the electric eraser of the present invention can be made relatively small, and the overall manufacturing cost can be effectively reduced.

[0047] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
