Abstract
A dual-purpose dustproof blackboard eraser device belongs to the technical field of culture and education appliances. The variety of blackboards used in schools is diversified at present, chalk marks are removed by utilizing a brush after the blackboard is filled with characters or by utilizing a sponge eraser, but the existing blackboard eraser does not simultaneously have the two functions, so that the blackboard is troublesome to clean, time and labor are wasted, and dust flies everywhere to influence the body health of teachers and students. The utility model adopts the technical scheme that a water cabin (6) is arranged inside a skeleton (1) with two side water inlet holes (5), the water cabin (6) is communicated with the two side water inlet holes (5), the skeleton (1) is provided with a water inlet hole screw cap (7), and the two side water inlet holes (5) are respectively communicated with a sponge eraser (2) and a brush eraser (3). The dual-purpose dustproof blackboard eraser device has the advantages that the dual-purpose dustproof blackboard eraser device is used for cleaning the chalk marks on different blackboards, so that simplicity in operation and time and labor conservation can be realized, flying dust can be avoided, and the body health of the teachers and the students can be guaranteed.
Description
Technical field
The utility model relates to culture and education apparatus device technique field, more specifically a kind of dual-purpose dust-proof blackboard eraser device.
Background technology
The blackboard type of at present school's use is more, what have after blackboard is write full word will wipe chalk writing with hairbrush, what have will wipe chalk writing with the sponge eraser, and the blackboard eraser that uses does not now possess these two kinds of functions simultaneously makes the troublesome poeration that the erases the board dust from flying of wasting time and energy affect the healthy of academics and students.
Summary of the invention
For overcoming above-mentioned shortcoming, the purpose of this utility model is a kind of dual-purpose dust-proof blackboard eraser device of design.Its technical scheme is: be provided with sump in the skeleton with the bilateral inlet opening, sump is connected with the bilateral inlet opening and communicates, be screwed with the inlet opening threaded cap on the skeleton, the bilateral inlet opening is connected with the hairbrush eraser with the sponge eraser respectively and communicates, be fixed with respectively sponge eraser and hairbrush eraser on the top and bottom of skeleton, the two ends of handgrip cover plate frame are inserted in the groove of two sides of skeleton.The advantage of this utility model is: this dual-purpose dust-proof blackboard eraser apparatus structure is reasonable in design, novelty is skillfully constructed, after sump filled with water, the inlet opening threaded cap good seal of screwing on, water in the sump penetrates in sponge eraser and the hairbrush eraser stand-by through the bilateral inlet opening: the blackboard type of at present school's use is more, what have after blackboard is write full letter written with chalk need to wipe writing with hairbrush, during wiping the two ends of handgrip cover plate frame are inserted in the groove of two sides of skeleton and cover the sponge eraser, hand is taken handgrip cover plate frame to wipe word with the hairbrush eraser and is got final product, what have need to wipe writing with the sponge eraser, during wiping the two ends of handgrip cover plate frame are inserted in the groove of two sides of skeleton and cover the hairbrush eraser, hand is taken handgrip cover plate frame to wipe word with the sponge eraser and get final product, dust from flying owing to being soaked with water in the sponge eraser and having avoided erasing the board; This device for blackboard eraser dual-use material uses it to wipe the chalk writing of the different blackboards time saving and energy saving dust from flying of having avoided simple to operate and guarantees that the academics and students's is healthy.
