Detailed Description

The utility model is described in further detail below with reference to the attached drawings and detailed description: referring to fig. 1-7, a dry and wet blackboard eraser comprises a box body 1, wherein a plurality of groups of dry cleaning pieces and wet cleaning pieces are arranged in the box body 1.

A plurality of baffles 2 are arranged in the box body 1, preferably, the number of the baffles 2 is two groups, then the baffles 2 divide the box body 1 into three areas, namely a first area 3, a second area 4 and a third area 5, wherein the second area 4 is positioned between the other two groups of areas, the first area 3 and the third area 5 are used for placing wet cleaning pieces, and the second area 4 is used for placing dry cleaning pieces.

Further, the second area 4 is slightly larger than the other two groups, a fixed table 6 is arranged in the second area 4, the fixed table 6 is used for placing dry cleaning elements, the fixed table 6 is fixed between the two groups of baffles 2, a movable table 7 is movably arranged in the first area 3 and the third area 5, the movable table 7 is used for placing wet cleaning elements, namely, the movable table 7 slides between the baffles 2 and the box body 1, and the sliding direction is far away from the box body 1 or near the box body 1.

The movable table 7 comprises connecting parts 8 at two ends, the connecting parts 8 at each side are connected with the inside of the box body 1 through a group of elastic pieces 9, the movable table 7 is always positioned in the box body 1 under the condition that the elastic pieces 9 have no external force, see fig. 4, the surface of the movable table 7 is lower than the surface of the fixed table 6, and when the blackboard eraser is placed on a whiteboard, the fixed table 6 is abutted to the surface of the movable table, so that cleaning can be realized.

For how to wipe the wet cleaning member and the dry cleaning member together with each other, a control assembly is provided in the case 1, and the control assembly can control the movable table 7 and the alignment with the fixed table 6, that is, one group of the wet cleaning member and the dry cleaning member can act on the whiteboard simultaneously, specifically, according to the wiping habit, the wiping of the whiteboard generally needs to wipe the wet cleaning member first and then the dry cleaning member is used for wiping, and then the whiteboard can be directly written.

The control assembly comprises a first inclined block 11, a second inclined block 12 and a push plate 10, referring to fig. 4, two groups of first inclined blocks 11 are arranged on two groups of movable tables 7, the first inclined blocks 11 can slide between the box body 1 and the baffle 2, and can not be blocked by the first inclined blocks 11 to be symmetrically arranged by the fixed tables 6, two groups of second inclined blocks 12 are arranged in the box body 1 in a matching manner, the push plate 10 is slidably arranged between the baffle 2, when the push plate 10 is slid for one time, only one group of movable tables 7 can be controlled, so that when the push plate 10 is pushed, the movable table 7 on the side with the same pushing direction moves in the direction away from the box body 1 against the elastic piece 9, namely, the wet cleaning piece is kept aligned with the dry cleaning piece, and acts on the white board.

Further, how to control the displacement of the push plate 10, two sets of push rods 13 are arranged at the centers of two sides of the push plate 10, the push rods 13 are penetratingly arranged on the box body 1, and when the handheld blackboard eraser acts on the whiteboard, the positions of the push rods 13 are controlled by fingers, so that the positions of the push rods 13 and the movable table 7 are controlled.
