Abstract
The invention discloses a dust-free blackboard eraser. The dust-free blackboard eraser comprises a blackboard eraser body, a connecting tube, a storage cabin, a dust erasing device, a cabin separation board and a suction fan. The blackboard eraser body comprises a dust erasing structure. The connecting tube is connected with the suction fan. The storage cabin is arranged below the suction fan. The dust erasing device is provided with a meshed structure. The cabin separation board is arranged below the suction fan. A dust outlet tube is connected with one end of the suction fan, and a dust suction tube is connected with the other end of the suction fan. The ground end of the dust suction tube is arranged in the dust erasing device. Since the suction fan is used as a dust suction device, good dust prevention effect is achieved without use of plugs with electric wires; the electric wires are not needed, so that resource waste is reduced.
Description
Technical field
The invention belongs to field of Environment Protection, particularly relate to a kind of dust-free black board eraser.
Background technology
At present, chalk dust in large quantities can be produced when using blackboard eraser to erase the board, chalk flies upward everywhere, what have drops on clothes, what have is drawn in health by the student of surrounding, teacher, not only the healthy of people is also endangered to the environment of surrounding: market also has electronic can the blackboard eraser of dust suction, but if electric wire electric leakage has very large harm to student otherwise just can not play dust-proof effect.
Summary of the invention
In order to overcome the defect of above-mentioned prior art, the object of this invention is to provide one and possess and conduct electricity very well, environmental-protecting performance is excellent, and a kind of dustless black print is wiped, and decreases the waste of resource.
The present invention takes following technical scheme to realize: a kind of dust-free black board eraser, it comprises blackboard eraser body, tube connector, storage warehouse, wiping dirt device, cabin body dividing plate, induced-draught fan and sweep-up pipe, described blackboard eraser comprises wipes dirt structure, tube connector link and induced-draught fan; Described storage warehouse is located at the below of induced-draught fan, described wiping dirt device is provided with network structure, described cabin body dividing plate is located at the below of induced-draught fan, and described induced-draught fan one end is connected to the dust outlet tube other end and is connected to sweep-up pipe, and the ground end of described sweep-up pipe is arranged on to be wiped in dirt device.
Described tube connector link is taken over induced-draught fan suction inlet chain.
Dust-exhausting port is provided with below described storage warehouse.
Air suction opening is provided with in described wiping dirt device.
Cabin body opening is set below above-mentioned dust-free black board eraser body; and this opening is positioned at the below of the soft bristle of blackboard eraser body; so when we erase the board; chalk dust all can suck in the cabin body of collection; chalk in this process is avoided to fly upward everywhere; on the body preventing chalk from dropping on the person of erasing the board or suck health, effectively protect academic environment not contaminated.
accompanying drawing explanation
Fig. 1 is cross-sectional structure schematic diagram of the present invention.
Wherein: 1, tube connector; 2, induced-draught fan; 3, storage silo; 4, dust-exhausting port; 5, sweep-up pipe; 6, dirt device is wiped; 7, induced-draught fan western entrance tube connector; 8, induced-draught fan dust removal port.
detailed description of the invention
As shown in Figure 1, the present invention takes following technical scheme to realize: a kind of dust-free black board eraser, it comprises blackboard eraser body tube connector 1, storage warehouse 3, wipe dirt device 6, cabin body dividing plate and induced-draught fan 2, described tube connector 1 connects induced-draught fan 7, induced-draught fan 7 one sections is provided with one section, inlet scoop and is provided with the weight that below storage warehouse that storage warehouse 3 described in air outlet is located at induced-draught fan 2 can collect the chalk dust of 5 grams, do not need often to wipe described in the dust in clear storage warehouse 3 dirt 6 device to be provided with network structure and to prevent from dust from leaking outside serving good collecting action, described cabin body dividing plate is located at the below of induced-draught fan, described induced-draught fan 2 one end is linked to ground end that the dust outlet tube other end is linked to sweep-up pipe 5 described in sweep-up pipe 5 and is arranged on and wipes in dirt 6 device.
Described tube connector connects and induced-draught fan suction inlet tube connector.
