Description
Technical field
The utility model relates to a kind of blackboard, relates in particular to a kind of electronic washing from the drying type dustproof blackboard.
Background technology
Because traditional blackboard uses blackboard eraser to wipe letter written with chalk, it is not fine wiping effect usually, and it is few to write powder utilization, and can produce the phenomenon of dust from flying in sassafras blackboard process, and the serious harm teachers and students are healthy.
Summary of the invention
The purpose of this utility model is to provide a kind of electronic washing from the drying type dustproof blackboard, and this blackboard can effectively prevent the harm of dust, reduces teaching profession's disease.
The utility model is achieved like this, it comprises live-roller, height adjustment bolt, flexible blackboard, writing backing plate, air supply duct, air-heater, motor, the water scraping blade, belt, gear, removable tank, foot pedal, point driving switch, lower driving roller, the grooved framework, clearer, corresponding respectively connection of upper and lower side that it is characterized in that the grooved framework gone up live-roller and lower driving roller, be with rotating flexible blackboard between last live-roller and the lower driving roller, bottom near lower driving roller is connected with clearer, clearer places in the removable tank, clearer is by the gear lower driving roller that is connected, lower driving roller connects motor by belt, motor connects point driving switch, the two ends of last live-roller are provided with height adjustment bolt, the flexible blackboard surface of clearer top is provided with the water scraping blade, water scraping blade top is provided with air-heater, the air outlet of air-heater connects air supply duct, the tube wall of air supply duct has several exhaust vents, water scraping blade and clearer two ends difference frame are in arc shaped groove, be connected with holddown spring in the arc shaped groove, and water scraping blade and clearer are by cord connecting pin pedal, the power supply of air-heater connects point driving switch by contact, contact, by cord connecting pin pedal, the flexible blackboard back side is provided with writing backing plate respectively for water scraping blade and clearer.
Technique effect of the present utility model is: by point driving switch control, clean a fritter blackboard at every turn, adopt the blackboard after washing is cleaned sparkling clean, effectively strengthen the powder utilization and the reflecting effect of blackboard; Adopting washing can prevent effectively that dust from influencing health, is the blackboard of a health; Adopt air-heater and air supply duct that uniform hot blast can be provided, rapidly the blackboard surface after the oven dry washing; Adopt height adjustment bolt, avoided the flexible blackboard face to be subjected to the influence of factors such as temperature, weather, air humidity; Simple in structure, cost is reasonable, the properties of product after the formation are stable, are easy to safeguard.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In the drawings, 1, go up live-roller 2, height adjustment bolt 3, flexible blackboard 4, writing backing plate 5, air supply duct 6, air-heater 7, motor 8, water scraping blade 9, belt 10, gear 11, removable tank 12, foot pedal 13, point driving switch 14, lower driving roller 15, grooved framework 16, clearer.
The specific embodiment
As shown in Figure 1, the utility model is achieved like this, corresponding respectively connection of the upper and lower side of grooved framework 15 gone up live-roller 1 and lower driving roller 14, be with rotating flexible blackboard 3 between last live-roller 1 and the lower driving roller 14, bottom near lower driving roller 14 is connected with clearer 16, clearer 16 places in the removable tank 11, clearer 16 is by gear 10 lower driving roller 14 that is connected, lower driving roller 14 connects motor 7 by belt 9, motor 7 connects point driving switch 13, the two ends of last live-roller 1 are provided with height adjustment bolt 2, flexible blackboard 3 surfaces of clearer 16 tops are provided with water scraping blade 8, water scraping blade 8 tops are provided with air-heater 6, the air outlet of air-heater 6 connects air supply duct 5, the tube wall of air supply duct 5 has several exhaust vents, water scraping blade 8 and clearer 16 two ends difference frame are in arc shaped groove, be connected with holddown spring in the arc shaped groove, and water scraping blade 8 and clearer 16 are by cord connecting pin pedal 12, the power supply of air-heater 6 connects point driving switch 13 by contact, contact, by cord connecting pin pedal 12, flexible blackboard 3 back sides are provided with writing backing plate 4 respectively for water scraping blade 8 and clearer 16.
During use:
1) press point driving switch, circuit imports motor into through the time relay, and motor drives lower driving roller (band transmission) and cleaning roller (gear drive) simultaneously;
2) lower driving roller promptly drives the flexible blackboard face and rotates, and cleaning roller promptly dips in water clean plate face from tank, and water is scraped the water on the flexible blackboard face is scraped simultaneously, and air-heater is started working, and the plate face is dried up rapidly;
3) circuit is disconnected when the time relay, just the rotate height of a fritter blackboard of flexible blackboard plate face, air-heater quits work simultaneously;
4) step on foot pedal, cleaning roller and water are scraped and are promptly left the plate face, and air-heater quits work simultaneously, the space of a whole page rotated when pressed point driving switch promptly realize retention plate face writing this moment, thereby the blackboard amount of writing is doubled, and unclamped foot pedal, under acting force of the spring, clearer and water are scraped and are resetted;
5) be subjected to factor affecting such as temperature, weather, air humidity, the flexible blackboard face may relax or tensioning, thus the influence use, and this moment, adjustable-height was regulated bolt, made flexible blackboard face degree of tightness moderate.
