Abstract
The purpose of this utility model is to provide a kind of environmental protection water spray blackboard eraser, comprises blackboard eraser, two-sided wiper, water injector and blackboard eraser holder box.Described two-sided wiper and water injector are installed on two corresponding surfaces of blackboard eraser respectively, and described water injector mainly comprises nozzle, depression bar, water storehouse, nozzle cover, bonnet, and described water storehouse, for storing running water, is pressed by depression bar, and running water can be sprayed by nozzle; Described jet expansion is placed in the one side of two-sided wiper.Before the utility model environmental protection water spray blackboard eraser uses, bonnet is turned on, running water is poured in water storehouse, during use, by moulded rod, running water can spray from nozzle, is sprayed by water on the teaching board, use two-sided wiper wiping board of education back and forth, thus reach the good result that water wipes hydrolysis teaching board.The utility model novel structure, combines water injector and blackboard eraser, more convenient during use, quick, effectively ensures good teaching environment, environmentally-friendly sanitary more simultaneously.
Description
Technical field
The utility model belongs to teaching aid technical field, is specifically related to a kind of environmental protection water spray blackboard eraser.
Background technology
Along with Internet era arrival, traditional blackboard and chalk teaching be projected just gradually instrument substitute, but, the use of projecting apparatus is nothing like conventional teaching in classroom interactions, the well atmosphere of classroom instruction can not be embodied more intuitively, at present, the general mode adopting projecting apparatus to combine with blackboard chalk is imparted knowledge to students.But traditional blackboard and chalk teaching, after blackboard eraser erases the board, can produce more dust, harm teachers and students are healthy, and affect classroom health, in addition, dust pollution also can cause badly damaged to classroom inner electronic equipment.
In recent years, the use of hydrolysis writing on blackboard effectively can solve chalk to the harm brought of imparting knowledge to students, use the writing on the blackboard that hydrolysis writing on blackboard is write, need first to use running water wiping, then two-sided wiper or the further wiped clean of sponge is used, but this wiping method is more loaded down with trivial details, the cleaning blackboard cost more time.
Utility model content
For solving the technological deficiency existed in above-mentioned prior art, the purpose of this utility model is to provide a kind of novel structure, integral type environmental protection easy to use water spray blackboard eraser, and water injector and blackboard eraser combine by this blackboard eraser, more convenient during use, quick.
A kind of environmental protection water spray blackboard eraser, comprises blackboard eraser, two-sided wiper, water injector and blackboard eraser holder box.Described two-sided wiper and water injector are installed on two corresponding surfaces of blackboard eraser respectively, and described water injector mainly comprises nozzle, depression bar, water storehouse, nozzle cover, bonnet, and described water storehouse, for storing running water, is pressed by depression bar, and running water can be sprayed by nozzle; Described jet expansion is placed in the one side of two-sided wiper.
Described blackboard eraser holder box is provided with bracket and pen container, and described bracket is for placing blackboard eraser, and described pen container is for placing Teaching pen; Be provided with magnet in described blackboard eraser holder box, can be adsorbed on the optional position of board of education.
Described two-sided wiper employing good water absorption, the cloth that wearability is high, two-sided wiper can be unpicked and washed at any time, change.
Before using the utility model environmental protection water spray blackboard eraser, bonnet is turned on, in water storehouse, pours into running water.During use, by moulded rod, running water can spray from nozzle, is sprayed by water on the teaching board, uses two-sided wiper wiping board of education back and forth, thus reach the good result that water wipes hydrolysis teaching board.
Blackboard eraser material adopts the explosion-proof plastics one-shot forming of high-quality ABS engineering to be made, sturdy and durable, and its circular arc corner is designed, and not easily collision causes injury.
Environmental protection of the present utility model water spray blackboard eraser is by water injector and blackboard eraser in one, and novel in structural design, practical, more convenient and quicker during use, more convenient bring to classroom instruction, effectively ensures good teaching environment, environmentally-friendly sanitary more simultaneously.
