Description

Dustless eraser

Technical field

The present invention relates to education instrument manufacturing technology field, especially a kind of blackboard erasers for teaching.

Background technique

In today that computer technology is popularized, some middle and primary schools are especially in some schools, teachers still adopt chalk The method of writing words is imparted knowledge to students on blackboard, it is well known that after chalk is write on blackboard, can be fallen perhaps with blackboard eraser wiping More chalk dusts, chalk dust cause healthy hidden danger to teacher and classmate on duty for the day.

Summary of the invention

The object of the present invention is to provide a kind of Dustless erasers, it can solve, and dust when current blackboard eraser erases the board is big to ask Topic.

To solve the above-mentioned problems, the technical solution adopted by the present invention is that:

This Dustless eraser, including closed lower chambers and the upper chamber connecting with the lower chambers, the lower chambers are logical It crosses through-hole to be connected to the upper chamber, the lower chambers are equipped with water inlet, and the water inlet is equipped with blanking cover；It is set in the upper chamber There is pedestal, blackboard eraser piece is equipped in the pedestal, the blackboard eraser piece stretches out outside the epicoele room housing, upper chamber's hull outside Equipped with water absorption layer；The water absorption layer is equipped with micropore and is connected to the upper chamber.

In above technical scheme, the further scheme may be that: the water absorption layer is made of sponge, the water suction layer surface Equipped with a plurality of groove.

Further: the epicoele room housing and water absorption layer are divided into movable part and fixed part, wherein two sides movable part The shell divided passes through hinge and the lower chambers housing hinge.

Further: the blackboard eraser piece is connect with the base runner.

Further: the blackboard eraser piece is fixedly connected with the pedestal.

Further: the cavity of resorption room housing and the epicoele room housing are made of plastic material；The blackboard eraser piece is by rubber Glue material is made.

By adopting the above-described technical solution, compared with prior art, the present invention has the following advantages:

1, the present invention is divided into two chambers up and down, and middle and lower chamber is water filling chamber, and upper chamber is provided with dismountable work Dynamic wiping board, its exterior is equipped with sponges, and micropore is equipped between upper chamber and sponge, is equipped with through-hole between upper and lower chamber；Bottom chamber Water upper chamber is entered by through-hole, and sponge is entered by micropore；2, the sponge outside upper chamber of the present invention is equipped with slot, chalk dust It falls through into slot, a possibility that being sucked when chalk dust is fallen by people can be greatly reduced；3, upper chamber of the present invention is equipped with from two sides Hinge open upper chamber can to two sides, be conveniently replaceable blackboard eraser piece.

Specific embodiment

The present invention is further described with reference to the accompanying drawings and examples:

Embodiment one:

Such as Fig. 1 ~ Dustless eraser shown in Fig. 3, including closed lower chambers 13 and the upper chamber 12 being connect with lower chambers 13, Lower chambers 13 are surrounded by shell 6, and upper chamber 12 is surrounded by shell 4, and the shell 6 of lower chambers 13 and the shell 4 of upper chamber 12 are by moulding Material is made, and upper chamber 12 and lower chambers 13 are cuboid；Lower chambers 13 are connected to by through-hole 10 with upper chamber 12, and lower chambers 13 are set There is water inlet 8, water inlet 8 is equipped with blanking cover 7, and the volume of upper chamber 12 is greater than the volume of lower chambers 13, upper chamber 12 and lower chambers 13 are connected by bonding agent；It is equipped with pedestal 3 in upper chamber 12, is equipped with blackboard eraser piece 2 in pedestal 3, in the present embodiment, blackboard eraser piece 2 has It two pieces, is made of rubber material, blackboard eraser piece 2 is actively plugged on pedestal 3；Blackboard eraser piece 2 stretches out outside the shell 4 of upper chamber 12, on The outside of the shell 4 of chamber 12 is equipped with water absorption layer 1；Water absorption layer 1 is equipped with micropore 5 and is connected to upper chamber 12；Water absorption layer 1 is by soft material It is made, in the present embodiment, soft material is sponge material, and 1 surface of water absorption layer is equipped with a plurality of groove 9, and water absorption layer 1 is viscous by bonding agent In the outer surface of the shell 4 of upper chamber 12；Blackboard eraser piece 2 is higher by water absorption layer 1.

The shell 4 and water absorption layer 1 of upper chamber 12 are divided into movable part and fixed part, wherein the shell of two sides movable part 4 is hinged by hinge 11 and the shell 6 of lower chambers 13, and the movable part and fixed part of upper chamber 12 are fixed by lock 14, When the abrasion of blackboard eraser piece 14 needs to change, lock 14 only need to be unclamped, shell 4 is opened outward, pedestal 3 and blackboard eraser piece 2 can be exposed It is replaced.

Embodiment two:

Such as Fig. 4 ~ Dustless eraser shown in fig. 5, upper chamber is semi circular chamber, and blackboard eraser piece is also made corresponding arc-shaped； Remaining feature is the same as example 1.

Embodiment three:

Such as Fig. 6 ~ Dustless eraser shown in Fig. 7, it is cavity in upper chamber that blackboard eraser piece, which is fixed on epicoele outdoor face, remaining It is the same as example 1, the present embodiment is disposable Dustless eraser, is thrown away after abrasion.
