Abstract
The invention provides an automatic erasing blackboard. The automatic erasing blackboard comprises a blackboard, an upper slide rail and a lower side rail, wherein the upper slide rail and the lower slide rail are positioned on the upper side and the lower side of the blackboard; a slide shaft A, a slide shaft B and a slide shaft C are arranged between the upper slide rail and the lower slide rail; a movable brush plate is arranged on the slide shaft A; the brush plate is connected with a water pipe; a wiper is arranged on the slide shaft B; a drier is arranged on the slide shaft C; the drier is connected with a hot air fan through an air pipe; meanwhile, a water groove is further formed below the lower slide rail. During use of the automatic erasing blackboard, chalk on the blackboard is cleared through the water-containing brush plate, water on the blackboard is wiped through the wiper, and the blackboard is dried through the drier. The operating time of the whole process is less than 1 minute, so that efficient operation is realized. Meanwhile, handwriting on the chalk blackboard is cleaned through water, so that freeness from dust is realized completely, and the health of students and teachers is protected.
Description
Technical field
The invention belongs to teaching aid field, particularly relate to a kind of auto-erasing blackboard.
Background technology
Along with the development of society, increasing convenience product is continuously created, and makes the life of the people, learning quality improves a class.Then, our health becomes the topic of popular extensive concern.Blackboard eraser is one of teaching aid that in teaching process, frequency of utilization is the highest, but due to not prompt enough to the cleaning of blackboard eraser or thorough not, often cause blackboard eraser can accumulate too much chalk dust, more and more unclean when making teacher sassafras blackboard, greatly have impact on efficiency of teaching, reducing quality of instruction, is a urgent problem at present.
According to the data display of Center for Disease Control of China, due to the carcinogen contained in dust, China's 3,800 ten thousand full-time teacher's cancer morbidities have accounted for 20% of Nattonal Cancer total incidence, are 8 times of ordinary group.And teachers in primary and middle schools' respiratory system Prevalence Rate of Chronic Diseases, as chronic pharyngitis and vocal cords disease, wherein the male sex is 58.53%, and women is 61.06%, and all has the trend raised with length of teaching growth.Wherein the illness rate of more than 5 years teacher's pharyngitis is almost 100%, rhinitis illness rate is 39%, asthma illness rate is 43%, bronchitic illness rate is 8%, the illness rate of pneumoconiosis is 11.76%; Further, teacher at school time, erase the board and can lose time, see at every turn teacher write writing on the blackboard a full plate, wiping of then taking time again, sensation teacher can be more tired.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of efficiency of erasing high, safety and environmental protection auto-erasing blackboard.
The present invention is achieved by the following technical programs.
A kind of auto-erasing blackboard provided by the invention, comprises blackboard; Also comprise and be positioned at the upper slide rail on the upside of blackboard and the glidepath on the downside of blackboard, slide-bar A, slide-bar B, slide-bar C are installed between upper slide rail and glidepath; Slide-bar A is provided with moveable brush board, and brush board is connected with water pipe; Slide-bar B is provided with wiper; Slide-bar C is provided with baker, and baker is connected with air-heater by tracheae, also has tank in the below of glidepath simultaneously.
Described brush board comprises delivery port and bristle.
Described bristle has four, has two tops being positioned at brush board, has two middle parts being positioned at brush board.
Described baker has venthole, and venthole is elongated air vent
Beneficial effect of the present invention is: this device is first by being with the brush board of water by totally clear for the chalk on blackboard, then by wiper, the water on blackboard is hung, eventually pass baker blackboard is dried, the whole process operation time was less than 1 minute, operation is efficient, meanwhile, this equipment by water by chalk black writing clean up, realize without dust completely, contribute to the health of student and teacher.

Detailed description of the invention
Further describe technical scheme of the present invention below, but described in claimed scope is not limited to.
A kind of auto-erasing blackboard as shown in Figure 1,2 and 3, comprises blackboard 1; Also comprise and be positioned at the upper slide rail 2 on the upside of blackboard 1 and the glidepath 3 on the downside of blackboard 1, be provided with slide-bar A4, slide-bar B6, slide-bar C8 between upper slide rail 2 and glidepath 3, slide-bar A4, slide-bar B6, slide-bar C8 can horizontally slip with glidepath 3 is cofree at upper slide rail 2; Slide-bar A4 is provided with moveable brush board 5, brush board 5 is connected with water pipe; Slide-bar B6 is provided with wiper 7; Slide-bar C8 is provided with baker 9, baker 9 is connected with air-heater 10 by tracheae, also has tank 11 in the below of glidepath 3 simultaneously; Described brush board 5 comprises delivery port 51 and bristle 52, and bristle 52 has four, has two tops being positioned at brush board 5, has two middle parts being positioned at brush board 5, according to this design can ensure brush board can by blackboard chalk cleaning cleaner; Described baker 9 has venthole 91, and venthole 91 is elongated air vents, and each region that can ensure blackboard can be dried.
When chalk write completely whole blackboard time, slide-bar A4, slide-bar B6, slide-bar C8 is on the right of blackboard, first start slide-bar A4 to be moved to the left, and brush board 5 is moved up and down, open the conduit switch of brush board 5, ensure that the rate travel of brush board 5 is more than five times of slide-bar A4 rate travel, when slide-bar A4 moves to certain distance, start slide-bar B6 to be moved to the left, the wiper 7 on slide-bar B6 is utilized to scrape in tank 11 by the water on blackboard, then start slide-bar C8 to be moved to the left, start air-heater 10 simultaneously, on slide rail C8, blackboard is dried by baker, then by slide-bar A4, slide-bar B6, slide-bar C8 is adjusted to low order end.
