Abstract
The invention relates to an environment-friendly blackboard eraser. The eraser comprises a casing and a glass bottle, wherein a bottleneck is formed in the upper end of the glass bottle, water is contained in the glass bottle, a power switch is arranged on the casing, a fixing frame is arranged in the casing, a dust brushing motor is fixedly connected onto the fixing frame, a motor shaft is arranged at the lower end of the dust brushing motor, the lower end of the motor shaft is fixedly connected with a ventilation brush, a flocking fixing ring is arranged on the edge of the bottom end of the casing, a vent hole I is formed in one side of the casing and is in sealed connection with the upper end of a ventilation hose along the inner edge, the ventilation hose is connected with an exhaust motor connected with the bottleneck, and the lower end of the ventilation hose is arranged in the water. The blackboard eraser has the benefits as follows: due to the design of the dust brushing motor, the ventilation brush and a damping spring, the eraser can be used for erasing a blackboard quickly and conveniently, and time and labor are saved; due to the design of the exhaust motor, the water, the glass bottle and the hose, the erased dust can be fully sucked, and secondary pollution is avoided; due to the design of a filter net, the dust can be sucked by water more easily, and the eraser is environment-friendly.
Description
Technical field
The present invention relates to a kind of environment-friendly dust-proof eraser.
Background technology
Blackboard eraser, as the term suggests be a kind of apparatus erased the board, being a kind of common equipment in current China education hardware facility, is generally on small rectangular plank, add flannelette or palm fiber is made.Above-mentioned conventional wiping blackboard structure is simple, easy to use, but this blackboard eraser exists following defect for writing more teacher: the first, wiping is too wasted time and energy; The second, easily cause dust pollution, have adverse effect to the health of academics and students; The dust not easy cleaning of three, the flannelette of blackboard eraser or palm fiber adhering to; Four, the operating period is too short, and loss is large.
Summary of the invention
The object of this invention is to provide a kind of environment-friendly dust-proof eraser, the wiping existed to overcome current existing blackboard eraser too wasted time and energy, easily cause dust pollution, non-easy cleaning, above-mentioned deficiency that the operating period is too short.
The object of the invention is to be achieved through the following technical solutions:
A kind of environment-friendly dust-proof eraser, comprise shell and vial, described vial upper end is provided with bottleneck, water body is provided with in vial, described shell is provided with power switch, motor fixing frame is provided with in shell, motor fixing frame is fixedly connected with brush dirt motor, brush dirt motor lower end is provided with motor shaft, described motor shaft lower end is fixedly connected with ventilation hairbrush, hair of planting on described ventilation hairbrush can simple and easyly be changed, extend working time, described shell bottom is provided with along edge plants a mao retainer plate, shell side is provided with air vent one, air vent one is tightly connected along inner edge place vent hose upper end, vent hose is connected with exhausting motor, exhausting motor is connected with bottleneck, described vent hose lower end is arranged in water body.
Further, described motor shaft outside is provided with damping spring, makes ventilation hairbrush can finite motion on motor shaft; Described ventilation hairbrush is provided with some air vents; Described vent hose external rings is provided with stator, and stator is provided with electric source line interface; Described vent hose inside is provided with power line, and described power line connects brush dirt motor and exhausting motor respectively; Be provided with screen pack in described vial, screen pack is positioned at water body inside; Described exhausting motor is connected with bottleneck by dustless passage interface ring plate; Described dustless passage interface ring plate is that bayonet socket is connected or is threaded with bottleneck.
Beneficial effect of the present invention is: the design of brush dirt motor, ventilation hairbrush and damping spring makes blackboard wiping quick and convenient, time saving and energy saving; The dust that the design of exhausting motor, water body, vial and flexible pipe makes blackboard wiping produce is fully absorbed, and produces secondary pollution when avoiding process collection dust; The design of screen pack, makes dust more easily be only absorbed by the water, environment-friendly and green.
