Abstract
The utility model relates to a novel vacuum cleaning blackboard eraser. The blackboard eraser consists of an eraser board basal body and an eraser body, wherein a rubber vacuum sleeve is sheathed on the eraser board basal body; air exit holes are arranged on the rubber vacuum sleeve; and dust suction holes are arranged on the eraser board basal body. In the utility model, the rubber vacuum sleeve is added for the original blackboard eraser; when in use, the hand extrudes the rubber sleeve slightly, and the vacuum is formed in the robber sleeve; by adopting the vacuum suction principle, the dust can be sucked into the cavity of the rubber vacuum sleeve and the eraser body. The novel vacuum cleaning blackboard eraser has the advantages that more dust are sucked, dust flying is avoided when the eraser is used, and human health and classroom environment are protected.
Description
Technical field
The utility model belongs to the school supply and stationery technical field, particularly a kind of novel evacuated dust absorption blackboard eraser.
Background technology
Existing blackboard eraser mostly is felt or soft collodion, blackboard wiping preferably, but all inevitably can not be adsorbed on fully on the rub body along with the increase dust of wiping, dust from flying is serious.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned deficiency, a kind of novel evacuated dust absorption blackboard eraser to be provided.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of novel evacuated dust absorption blackboard eraser, form by wiping board matrix and rub body, be set with the rubber vacuum envelope on the wiping board matrix, the rubber vacuum envelope is provided with steam vent, the wiping board matrix is provided with the dust inlet hole, when the rubber vacuum envelope was provided with a steam vent, dust is adsorbed onto rub body and the effect above the vacuum envelope is best.
The utility model is to have utilized vacuum adsorption principle, on common blackboard eraser basis, increase by a rubber vacuum envelope, compressing rubber cover during use, the increase vacuum envelope along with dust during blackboard wiping recovers original form gradually, the dust that flies upward is adsorbed onto rub body and above the vacuum envelope.
The beneficial effects of the utility model are: can avoid flying upward of dust everywhere.Can adsorb more dust than the blackboard eraser of routine, reduce health harm user and student.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described further.
Fig. 1 is the utility model structural representation.
Fig. 2 is a wiping board matrix plan structure schematic diagram of the present utility model.
Among the figure: 1, steam vent, 2, the rubber vacuum envelope, 3, the wiping board matrix, 4, rub body, 5, air suction opening.
The specific embodiment
With reference to schematic diagram, the utility model is made up of wiping board matrix 3 and rub body 4, is set with rubber vacuum envelope 2 on the wiping board matrix 3, and rubber vacuum envelope 2 is provided with steam vent 1, and wiping board matrix 3 is provided with dust inlet hole 5.With the light compressing rubber vacuum envelope 2 of have gentle hands, the inside air is easy to discharge by steam vent 1 before bringing into use.The user can block steam vent 1 blackboard wiping with forefinger or other fingers when blackboard wiping, can return to original shape automatically at blackboard wiping process kind rubber vacuum envelope 2, because wiping board matrix 3 is provided with a plurality of air suction openings 5, at this time the dust along with wiping increases, dust can be adsorbed onto in rub body 4 and the rubber vacuum envelope 2 under the vacuum suction effect, along with the action of wiping board is finished, rubber vacuum envelope 2 also returns to original shape.Can carry out a next wiping then.Along with increasing of dust, can take off rubber vacuum envelope 2, the water flushing is promptly reusable.
