Abstract
The utility model provides a water-containing dust-collecting blackboard eraser and is characterized in that the blackboard eraser is a hollow body, a working chamber, a negative pressure chamber and a dust-collecting chamber are arranged inside the blackboard eraser. A mini motor and a battery pack for providing power supply for the mini motor are arranged inside the working chamber, and impellers are sleeved on the output shaft of the mini motor. A dust-collecting hole is formed at the bottom of the negative pressure chamber. A chalk dust inlet port is arranged between the negative pressure chamber and the dust-collecting chamber. A cleaning door is arranged on the side wall of the dust-collecting chamber. A water-storage rubber sac is arranged between the bottom of the blackboard eraser and bristles. The water-storage rubber sac is provided with a round hole at a site opposite to the dust-collecting hole at the bottom of the negative pressure chamber. Droplet holes are formed on the interface between the water-storage rubber sac and the bristles. The water-containing dust-collecting blackboard eraser can wet and clean the blackboard and simultaneously collect chalk dust in the dust-collecting chamber, thereby ensuring the surface of the blackboard is clean and the letters on the blackboard are clear, improving eye fatigue, and protecting the health of teachers and students.
Description
Technical field
The utility model relates to a kind of blackboard eraser, particularly relates to a kind of ash-collecting blackboard eraser with water, is to the improvement of existing wiping blackboard structure, belongs to the school supply and stationery category.
Background technology
At present, the used blackboard eraser of people is normal style: inlay a body brush on the rectangle plank, when erasing the board, chalk dust flies upward everywhere, has promptly polluted the environment in the classroom, again the healthy of academics and students is damaged to some extent.For addressing this problem, someone has developed ash-collecting blackboard eraser, though the phenomenon that chalk dust flies upward is everywhere solved, but it is unclear to leave over behind the blackboard eraser that the handwriting is blurred, make the word of newly writing up unintelligible, can be overlapping and make the people recognize unclear with the old word of not cleaning, easily cause visual fatigue, even cause myopia, bring difficulty for student's study.
The utility model content
The purpose of this utility model is to overcome the prior art above shortcomings, by improvement to existing wiping blackboard structure, provide a kind of ash-collecting blackboard eraser with water, this novel blackboard eraser is when being drawn onto chalk dust in the dust room, can also the wet rubbing blackboard, the plate face of blackboard is more cleaned, the word of newly writing up is more clear, thereby improved asthenopic degree, healthy useful to the academics and students.
The ash-collecting blackboard eraser of this band water that the utility model provides, include the blackboard wiping board, the bottom surface of blackboard wiping board is provided with snag, be characterized in that described blackboard wiping board is a ducted body, be provided with the operating room in the blackboard wiping board, negative pressure cavity and dust suction chamber, inside, operating room is provided with micromotor and supplies with the battery pack of miniature electric mechanomotive force, micromotor extend on the output shaft of negative pressure cavity and is with impeller, the bottom of negative pressure cavity is provided with air suction opening, be provided with chalk dust between negative pressure cavity and the dust suction chamber and advance the chamber mouth, but the dust suction chamber sidewall is provided with the clean-out door of switch, be provided with water storage capsule between blackboard wiping board bottom surface and the snag, also be provided with a circular hole on the corresponding position of air suction opening of this water storage capsule and negative pressure cavity bottom, the contact-making surface of this water storage capsule and snag is provided with the droplet hole, this water storage capsule is provided with the water inlet of band plug, also is provided with switch on the plate face of blackboard wiping board.
Compared with prior art, the beneficial effects of the utility model are: when being drawn onto chalk dust in the dust room, and can also the wet rubbing blackboard, the plate face of blackboard is more cleaned, the word of newly writing up is more clear, thereby has improved asthenopic degree, healthy useful to the academics and students.

Fig. 2 is the upward view of Fig. 1; Fig. 3 is the right view of Fig. 1.
The specific embodiment
As Fig. 1～shown in Figure 3, the ash-collecting blackboard eraser of this band water, include blackboard wiping board 1, the bottom surface of blackboard wiping board 1 is provided with snag 2, blackboard wiping board 1 is a ducted body, be provided with operating room 3 in the blackboard wiping board 1, negative pressure cavity 4 and dust suction chamber 5,3 inside, operating room are provided with micromotor 6 and supply with the battery pack 7 of miniature electric mechanomotive force, micromotor 6 extend on the output shaft of negative pressure cavity 4 and is with impeller 8, the bottom of negative pressure cavity 4 is provided with air suction opening 9, be provided with chalk dust between negative pressure cavity 4 and the dust suction chamber 5 and advance chamber mouth 16, but dust suction chamber 5 sidewalls are provided with the clean-out door 10 of switch, be provided with water storage capsule 11 between blackboard wiping board 1 bottom surface and the snag 2, also be provided with a circular hole 12 on the air suction opening 9 corresponding positions of this water storage capsule 11 and negative pressure cavity 4 bottoms, this water storage capsule 11 is provided with droplet hole 13 with the contact-making surface of snag 2, and this water storage capsule 11 is provided with the water inlet 14 of band plug, also is provided with switch 15 on the plate face of blackboard wiping board 1.
When wiping word at ordinary times, the plate face of holding blackboard wiping board 1 touch the letter written with chalk place with snag 2 writing is wiped, Push switch 15, connect power supply, micromotor 6 output shaft impeller 8 are rotated together, make the inside of negative pressure cavity 4 form negative pressure, by air suction opening 9 chalk dust is sucked in the dust suction chamber 5, when the dust collection many time, draw back clean-out door 10, wait to reuse after pouring out dust.Need firmly push the water storage capsule 11 between blackboard wiping board 1 bottom surface and the snag 2 during owing to erase the board, water under increased pressure in the water storage capsule 11 is flowed in the snag 2 by droplet hole 13, makes snag 2 become wet, thereby the blackboard panel after the wiping is more cleaned, and the word of newly writing up is more clear.
