Abstract
The utility model relates to a novel blackboard eraser which comprises an eraser body (1) and an erasing cloth (2). The eraser body (1) is of a box structure, a separation plate (3) is arranged in the eraser body (1) and separates the eraser body (1) into a front part and a rear part, the front part of the eraser body (1) is connected with a water storage box (5) through a water conveying pipe (4), and a plurality of water outlets (6) are formed in the bottom face of the front part of the eraser body (1); an electric heating wire (7) and a fan (8) which are connected in parallel are arranged in the rear part of the eraser body (1), a vent hole (9) is formed in the bottom face of the rear part of the eraser body (1), and a holding handle (10) and a power switch (11) are arranged on the top face of the eraser body (1). Due to the fact that the water storage box is connected with the eraser body of the novel blackboard eraser and the electric heating wire and the fan are arranged in the eraser body, dust can not be generated due to the wetted erasing cloth in the blackboard erasing process, hot air generated through the electric heating wire and the fan can blow the blackboard dry quickly, and therefore erasing efficiency is improved.
Description
Technical field
The utility model relates to a kind of teaching aid, particularly a kind of blackboard eraser.
Background technology
Traditional blackboard eraser is made of rub body and snag, in the process that erases the board clearly, can produce a large amount of dust, thereby affect the healthy of teachers and students, and it is long to dry clearly the dry time with wet cloth, can affect again the normal use of blackboard, therefore traditional blackboard eraser is difficult to satisfy people's needs.
Summary of the invention
The technical problems to be solved in the utility model is: overcome the deficiency that traditional blackboard is wiped, provide a kind of journey of nuzzling up clearly can avoid producing the novel blackboard eraser of dust.
For realizing above-mentioned technical problem, the technical solution of the utility model is:
A kind of novel blackboard eraser comprises rub body and wiper, and rub body is a box like structure, is provided with a dividing plate in the rub body, two parts before and after dividing plate is divided into rub body, and the front portion of rub body connects storage tank by a water-supply-pipe, and the bottom surface of rub body front portion is provided with a plurality of delivery ports; Be provided with the heating wire and the blower fan that are connected in parallel in the rub body rear portion, the bottom surface at rub body rear portion is provided with air vent, is provided with a lever and a power switch at the rub body end face.
After adopting technique scheme, the beneficial effects of the utility model are:
Because the rub body of this novel blackboard eraser connects storage tank, and is provided with heating wire and blower fan in the rub body, moistening wiper can not produce dust when therefore erasing the board clearly, and the hot blast that heating wire and blower fan produce can dry up blackboard fast, thereby has improved clear wiping efficient.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
The specific embodiment
As shown in Figure 1: a kind of novel blackboard eraser, comprise rub body 1 and wiper 2, rub body 1 is a box like structure, be provided with a dividing plate 3 in the rub body 1, two parts before and after dividing plate 3 is divided into rub body 1, the front portion of rub body 1 connects storage tank 5 by a water-supply-pipe 4, and the bottom surface of rub body 1 front portion is provided with a plurality of delivery ports 6; Be provided with the heating wire 7 and the blower fan 8 that are connected in parallel in rub body 1 rear portion, the bottom surface at rub body 1 rear portion is provided with air vent 9, is provided with a lever 10 and a power switch 11 at rub body 1 end face.
When using this novel blackboard eraser to erase the board, open the valve of water-supply-pipe 4, hold lever 10 back and forth wiping on blackboard, because the water in the storage tank 5 will pass through water-supply-pipe 4 and delivery port 6 moistening wipers 2, therefore can avoid producing dust, turn on the power switch 11 after wiping is complete, then heating wire 7 and blower fan 8 cooperate the hot blast that produces to blow to blackboard from air vent 9, thus the rapid draing blackboard.
