[Previous technology] Press; The eraser generally used for erasing chalk chalk on the blackboard is usually made of cloth. When this cloth blackboard eraser is used, it will not only wipe the chalk dust away, but also remove it. When it is necessary to pat the chalk ash by flapping, the chalk ash flying in the environment not only causes respiratory pollution to users, affects physical health, but also causes harm to the environment, which is not ideal. [Content] The main purpose of this creation is to provide an improved structure of a blackboard eraser, which makes the dust of the pen easy to erase, prevents it from flying around, is easy to manage, and can be removed and washed for repeated use to form an environmental protection effect. The aforementioned blackboard eraser structure is provided with a box body, a symmetrical semi-circular groove is arranged inside the inner side of the box, and a slit is formed in the center of the semi-circular groove, and two sides of the semi-circular groove are respectively provided with a buckle groove, and a brush is provided in the center. , The surface of the body is provided with a liftable upper cover, and a brush corresponding to a semi-circular slot cutout is provided on the inner edge of the upper cover, so that the two soft rollers are fastened to the groove by the shaft piece and the fixing piece to form a blackboard eraser When in use, by using a roller to scroll along the blackboard, the chalk marks are glued to make the erasure of chalk dust more convenient and clean. Continued pages (note that the new description page is not enough, please note and use the continuation page) M249834:. The new type of i discusses the aforementioned blackboard eraser structure, where the upper cover and the semi-circular groove are a closed space to make the roller After the chalk dust is adhered, it is removed by brush to fall into the confined space. When the cover is opened, the chalk cover is opened to pour out the chalk dust, which avoids the lack of conventional environmental pollution caused by slapping the cloth wipes. [Embodiment] Please refer to the first and second and third and fourth figures at the same time, which are the three-dimensional view, the exploded view, the vertical section view and the horizontal section view of this creation. This creation is mainly provided with a box body 1, a symmetrical semi-circular groove 11 is provided on the inner edge of the box 1, and a longitudinal slit 111 is provided at the center of the semi-circular groove 11, and the two ends of the semi-circular groove 11 are respectively provided. There is a buckle groove 12 connected by a semi-circular groove and an elongated groove, and a brush 13 is protruded between the two semi-circular grooves 11; the surface of the box body 1 is provided with a liftable upper cover 14 between the upper cover and the two semi-circular grooves 11. A closed space is formed, and the bottom edge of the upper cover 14 is provided with a hair brush 15 corresponding to the cutout of the semi-circular groove 11; two soft rollers 2 are fixed at both ends by a shaft piece 21 and a fixing piece 22, of which, The shaft pieces 21 are symmetrical protrusions 211 for fixing to the end cross section of the roller, and a protruding round shaft 212 is provided in the center. The fixing piece 22 corresponds to the buckle groove 12 and a round hole is provided in the center. 221, after the circular shaft 212 of the shaft piece 21 is sleeved in the circular hole 221 of the fixing piece 22, the shaft piece 21 and the fixing piece 22 are respectively fastened and fixed to the fastening groove I2, I] Continued page (new description page If it is not enough, please note and use the continuation page) M249834 New Manual Continuation Page Put the roller 2 in the semi-circular groove η; Together, it constitutes a blackboard eraser 100. When in use, the roller 2 is rolled along the eraser to stick the chalk dust on the blackboard, and then it is removed by a brush 13 provided in the cutout 111, so that the chalk dust falls on the The enclosed space makes the erasure of the chalk ash more convenient and clean, and avoids the chalk ash flying around. When the cover is closed, the upper cover 4 is opened and the chalk ash is poured out from the closed space to achieve the purpose of environmental protection. Please refer to the fifth and sixth figures at the same time, which are the examples of the use of this creation. In the use of this work, the box 1 is held in hand, and the roller 2 is rolled along the blackboard 3, and the chalk ash attached to the blackboard 3 is adhered by the electrostatic characteristics of the roller 2. When the roller 2 continues to roll, S The chalk ash occupying the surface will pass through the brush 15 so that the brush will remove the chalk ash into the closed space. During the entire wiping process, the brush 13 provided between the rollers 2 will also brush the blackboard. Make the blackboard cleaner. When used for a period of time, the user can open the upper cover 14 to pour out the chalk dust in the closed space to facilitate management and prevent the chalk dust from flying around, causing environmental pollution. To sum up, this work uses a roller wheel and a brush to make the blackboard eraser more convenient to use. It is easier to erase chalk dust and easier to manage. It is a practical design and is a novel creation. He filed a patent application in accordance with the law, and the Qijun Bureau examined it.
