[0044] As Embodiment 1 of the present utility model, an eraser with a cleaning tool is shown, such as Figure 2As shown in the figure, it includes an eraser core 1, a housing 2, and a cleaning component 3. The housing 2 includes a first housing 21 and a second housing 22 that are connected to each other. A first cavity 6 is provided in the first housing 21. A first opening 24 communicating with the first cavity 6 is provided on the first housing 21. A debris collection structure 61 is provided in the first cavity 6. An installation seat 5 is provided on the second housing. The eraser core 1 is connected to the second housing 22 through the installation seat 5, which is convenient for holding, improves the use feel, and is convenient for carrying. The cleaning component 3 is arranged in the first cavity 6 and includes a rotating shaft 31 rotatably connected in the first cavity 6 and a brush member 32 arranged along the circumferential direction of the rotating shaft 31. The brush member 32 extends partially outside the first housing 21 through the first opening 24. The brush member 32 can drive the rotating shaft 31 to rotate relative to the first housing 21 by contacting the surface of media such as books and notebooks covered with eraser debris and transfer the adsorbed eraser debris to the debris collection structure 61, thereby cleaning the eraser debris generated when using the eraser, which is convenient for cleaning, improves the use experience of the eraser, and has a simple structure and is easy to control costs. In this embodiment, both the eraser core 1 and the second housing 22 are arranged in a cuboid structure. In other embodiments, they can also be arranged in a cylindrical shape or other structures. In other embodiments, anti-slip patterns can be added to both sides of the first housing and the upper surface of the second housing. The anti-slip patterns can be arranged in raised or recessed strip-shaped, dot-shaped, etc., to increase the friction when pushing the housing and facilitate practical use.

[0045] As Figure 4 shown, a debris collection structure 61 is connected to the first housing 21. The debris collection structure 61 and the first housing 21 surround to form an eraser debris collection space. The debris collection structure 61 is arranged along the length direction of the first opening 24. The cleaning component 3 is in the central position of the first opening 24, and the height of the debris collection structure 61 relative to the first housing 21 is equal to or lower than the height of the rotating shaft 31 relative to the first housing 21. With this setting, it can be ensured that when the cleaning component 3 operates, the eraser debris adsorbed on the brush member 32 can be smoothly transferred into the debris collection structure 61.

[0046] As Figure 4 shown, the debris collection structure 61 includes a collection bottom plate 611 connected to the first housing 21 and a baffle 612 connected to one side of the collection bottom plate 611 close to the rotating shaft 31. One side of the baffle 612 forms a partition surface 613 of the debris collection structure 61, and the other side forms a guiding surface 614 for guiding eraser debris into the debris collection structure 61. The guiding surface 614 is arranged parallel to the tangential direction of the brush member 32 and can abut against the free end of the brush member 32. When the cleaning component 3 operates, the rotating shaft 31 drives the brush member 32 to roll, adsorbing the eraser debris on the free end of the brush member 32 and turning it into the first cavity 6. The eraser debris can fall into the debris collection structure 61 along the guiding surface 614 smoothly.

[0047] As Figure 4As shown, the top end of the guiding surface 614 is connected to the top end of the partition surface 613 to form a first sharp-corner structure 615, and the bottom end of the guiding surface 614 is connected to the outer side surface of the first housing 21 to form a second sharp-corner structure 616, facilitating the rubber chips on the brush member 32 to fall into the debris collection structure 61.

[0048] As Figure 4 shown, there are two debris collection structures 61, and the two debris collection structures 61 are respectively arranged on both sides of the first opening 24 and the cleaning assembly 3. With this design, it can effectively ensure that the rubber chips adsorbed on the brush member can fall into the debris collection structure without dropping.

[0049] As Figure 7 shown, the cleaning assembly 3 further includes a rolling body 33 connected to the rotating shaft 31 and rotating synchronously with the rotating shaft 31. The rolling body 33 partially extends out of the first housing 21 through the first opening 24. The distance between the circumferential side surface of the rolling body 33 and the rotating shaft 31 is less than the distance between the free end surface of the brush member 32 and the rotating shaft. The rolling body 33 can roll while rubbing against the external medium, and drive the rotating shaft 31 and the brush member 32 to rotate relative to the first housing 21 around the axis of the rotating shaft 31, adding support to the cleaning assembly by the rolling body, which is more conducive to driving the housing and the cleaning assembly to move on the external medium, generating a better cleaning effect. The rolling body surface can be provided with a friction pattern structure to improve the friction effect and anti-slip property. In this embodiment, rolling bodies 31 are respectively arranged at both ends of the rotating shaft 31, and the brush member 32 is arranged between the two rolling bodies 31, providing better stability and steadiness for the support of the cleaning assembly. Of course, in other embodiments, only one rolling body 31 can be provided, or three, four or even more rolling bodies 31 can be provided. The position of the rolling body 31 can be at both ends of the brush member 32, or at the middle position or other positions between the two ends of the brush member 32, all of which can support the cleaning assembly.

[0050] As Figure 7 shown, a positioning shaft 331 protrudes outward along its axis from the middle of the side of the rolling body 33 away from the brush member 32. A fixing channel 333 is arranged between the rolling body 33 and the positioning shaft 331. The end of the rotating shaft 31 is inserted into the fixing channel 333 to be fixedly connected with the rolling body 33. In other embodiments, the fixing channel 333 can be only arranged in the middle of the rolling body 33 without the positioning shaft, and the end of the rotating shaft 31 is inserted into the fixing channel 333 to be fixedly connected with the rolling body 33, which can also achieve the connection function between the rotating shaft 31 and the rolling body 33.

[0051] As Figure 5As shown, a positioning channel 332 is provided on the first housing 21 corresponding to the positioning shaft 331. The rotating shaft 31 and the first housing 21 are rotatably connected by inserting the positioning shaft 331 into the positioning channel 332. In an embodiment without the rolling element 33, the rotating shaft 31 can be directly inserted into the positioning channel 332 for rotatable connection. In this embodiment, the positioning channel 332 protrudes from the positioning plate 215 on the inner wall of the first housing 21. In other embodiments, the positioning channel 332 can be recessed on the inner wall of the first housing 21, such as Figure 10 shown.
