Abstract
The utility model discloses a water-spraying blackboard eraser which comprises a rectangular bottom board (1). An erasing cotton body (2) is fixed on the front side of the bottom board (1), two-three rows of center holes (3) are reserved on the erasing cotton body (2) uniformly, each center hole (3) penetrates through the erasing cotton body (2) along the thickness direction, a nozzle (4) with a water spray orifice(5) is arranged in each center hole (3), each water spray orifice (5) is communicated with a corresponding main pipe (6) in the bottom board (1), outer ends of the main pipes (6) are communicated with a soft water bag (7), a water filling port (8) is reserved at a connecting end of the soft water bag (7), and an end cap (9) is arranged on the water filling port (8). By arranging the water spray orifices, the main pipes and the soft water bag on the blackboard eraser, water in the soft water bag can be splashed onto a blackboard during blackboard erasing, dust flying in the erasing process is reduced greatly, dust pollution is reduced effectively, and the water-spraying blackboard eraser is simple, practical, environment-friendly and healthy.
Description
Technical field
The utility model relates to a kind of stationery and sporting goods, specifically, and particularly a kind of water spray chalkboard eraser.
Background technology
Common chalkboard eraser is wiped letter written with chalk by the cotton body of soft wiping, still, in the process of erasing chalk word, can produce more dust due to the cotton body of soft wiping of chalkboard eraser, falls down and flies upward everywhere, and the people who erases the board will be subject to serious dust pollution; Simultaneously, dust also can fly and fill the air whole classroom in the classroom civil strike, affects the air quality in the classroom, and the healthy of student or teacher worked the mischief.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of water spray chalkboard eraser that can effectively reduce dust from flying.
the technical solution of the utility model is as follows: a kind of water spray chalkboard eraser, comprise rectangular base plate (1), be fixed with in the front of base plate (1) and wipe cotton body (2), evenly have 2-3 row mesopore (3) in the front of the cotton body of described wiping (2), each arranges the front that mesopore (3) through-thickness runs through wiping cotton body (2) and extends to base plate (1), be provided with shower nozzle (4) in each described mesopore (3), each shower nozzle (4) protrudes from the positive one of base plate (1) and forms, have hole for water spraying (5) in shower nozzle (4), each hole for water spraying (5) be arranged on trunk line (6) connection corresponding in base plate (1), base plate (1) is stretched out in the outer end of trunk line (6), and is communicated with the soft water capsule (7) that is fixed on base plate (1) back side, has filler (8) at the link of soft water capsule (7), and this filler (8) are provided with end cap (9).
The utility model is offered many row's mesopores by wiping at chalkboard eraser on cotton body, shower nozzle and hole for water spraying are set in each mesopore, and each hole for water spraying is communicated with by trunk line with the soft water capsule.So, when with the chalkboard eraser blackboard wiping, hand is just in time pinched on the soft water capsule at the chalkboard eraser back side, and when firmly pinching, the water in the soft water capsule will be extruded out, and spray from hole for water spraying and splash on blackboard by trunk line.Like this, in the time of the chalkboard eraser blackboard wiping, blackboard also wets, and can reduce greatly flying upward of dust in wiping process, has effectively reduced dust pollution, and is both simple and practical, again environment protection health.
The aspect ratio of described shower nozzle (4) is wiped the little 2-5mm of height of cotton body (2).Like this, in the time of wiping, shower nozzle can not contact with blackboard, has avoided the interference of shower nozzle and blackboard; Simultaneously, it is too large that the distance of shower nozzle and blackboard also is unlikely to, and the water of hole for water spraying ejection is sprayed onto on blackboard as far as possible.
The aperture of described hole for water spraying (3) is 1-2mm.Like this, both can guarantee injection flow rate, and also can guarantee higher water-jet velocity, water can be sprayed onto blackboard as far as possible and get on.
Beneficial effect: the utility model arranges shower nozzle and hole for water spraying by wiping in cotton body mesopore at chalkboard eraser, and for hole for water spraying is equipped with the soft water capsule, the soft water capsule is connected by trunk line with hole for water spraying, so, when blackboard wiping, hand is pinched the soft water capsule, and the water in the soft water capsule will splash on blackboard from the spray orifice ejection.Like this, in the time of the cotton body blackboard wiping of chalkboard eraser, blackboard also wets, and can reduce greatly flying upward of dust in wiping process, has effectively reduced dust pollution, and is both simple and practical, again environment protection health.
