Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention.
The present invention provides a kind of technical solution referring to FIG. 1-2,：A kind of blackboard eraser, including blackboard eraser box body 1, spongy layer
2, absorbent wool 3, water storage box 5 and piston cylinder 10, the bottom and top of blackboard eraser box body 1 are respectively equipped with spongy layer 2 and absorbent wool 3,
The left side front and back of blackboard eraser box body 1 is equipped with observation panel, convenient for users to the water storage in observation water storage box 5 at any time
Amount, convenient for users to timely to being filled the water in water storage box 5, passing through between spongy layer 2 and absorbent wool 3 and blackboard eraser box body 1 solid
Determine snap ring 4 to be connected, the outer wall of fixing clasp 4 and the inner wall of blackboard eraser box body 1 are respectively corresponded equipped with tongue and groove, and fixing card
Ring 4 and blackboard eraser box body 1 are plug-in mounting structure, so that the blackboard eraser is in use for some time to 3 He of absorbent wool
Spongy layer is replaced and cleaned more convenient into 2 rows, and the inner cavity of blackboard eraser box body 1 is equipped with water storage box 5, and the bottom of water storage box 5 is also logical
It crosses outlet pass 7 to be connected with isocon 8, the right side inner cavity of blackboard eraser box body 1 is respectively equipped with piston rod fixed sleeving 9, piston cylinder
10 and cushion chamber 14, piston rod fixed sleeving 9 is mounted on the right side of piston cylinder 10, and the inner cavity of piston cylinder 10 is equipped with piston 11,
The inner cavity of piston 11 is connected with piston rod 12, and the bottom of piston cylinder 10 is connected by air-flow connecting tube 13 with cushion chamber 14,
The right side of cushion chamber 14 is equipped with air vent 15, and the left side of cushion chamber 14 is connected with water storage box 5 by air-flow connecting tube 13, is delayed
It rushes between chamber 14 and air vent 15 and water storage box 5 and is equipped with one-way flow box 16, blackboard eraser of the present invention, structure is simple, makes
Used time, user push piston 11 by piston rod 12, and the water in its water storage box 5 is made to pass through outlet pass 7 and isocon 8 for sponge
Layer 2 soaks, and can thus make user is not in dust in the chalk writing on erasing the board, and the blackboard after wiping
Compared to traditional blackboard wiping blackboard will completely much, in addition, user is after wiping blackboard using spongy layer 2,
The region of wiping is dabbed one time again by the absorbent wool 3 being arranged at the top of blackboard eraser box body 1 again, by water stain suction remaining on blackboard
Receive it is clean, with prevent on blackboard it is water stain it is dry after, leave a trace on blackboard, influence blackboard cleaning and handwriting it is clear
Clear degree.
Working principle：The blackboard eraser is in use, user is made in its water storage box 5 by the promotion piston 11 of piston rod 12
Water is soaked spongy layer 2 by outlet pass 7 and isocon 8, thus user can be made in the chalk writing on erasing the board
It is not in dust, and the blackboard after wiping will completely much, in addition, user exists compared to the blackboard of traditional blackboard wiping
After being wiped using spongy layer 2 to blackboard, then the absorbent wool 3 by being arranged at the top of blackboard eraser box body 1 is again to the region of wiping
Dab one time, by blackboard it is remaining it is water stain absorb cleanly, with prevent on blackboard it is water stain it is dry after, trace is left on blackboard
Mark influences the cleaning and the clarity of handwriting of blackboard, needs to further illustrate：When piston 11 moves outward, delay
The one-way flow box 16 rushed between chamber 14 and air vent 15 is circulation status, the one-way flow between cushion chamber 14 and water storage box 5
Box 16 is in off state, and when piston is to move inward, otherwise the one-way flow box 16 between cushion chamber 14 and air vent 15 is
Closed state, the one-way flow box 16 between cushion chamber 14 and water storage box 5 is circulation status, and makes the gas in water storage box 5
It presses pressure to increase, so that the water in water storage box 5 enters isocon 8 along outlet pass 7, and then spongy layer 2 is soaked, when water storage box 5
Then water flow stops flowing under the action of pressure when interior air pressure pressure is consistent with extraneous pressure.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with
A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding
And modification, the scope of the present invention is defined by the appended.
