This utility model is contemplated to solve the problems referred to above existing for current blackboard eraser, a kind of blackboard eraser provided。

This utility model realizes by techniques below scheme。

A kind of blackboard eraser, including handheld board and cotton, also includes expansion link, handle, there are press button, charge port in described handheld board side, there are water-storing box, dehydrator, battery in inside, cotton is fixed in handheld board, on the contact surface of handheld board and cotton, has evenly distributed tiny holes, communicate with water-storing box,, there are dehydrator air outlet and water filling port in the handheld board back side, and water filling port has lid。

Post-drying machine air outlet opened by described press button has hot blast to produce by boasting。

Water in described water-storing box, it is possible to slowly penetrate on cotton via the tiny holes in handheld board front。

Described charge port can be used for charging to the battery in blackboard eraser。

This utility model obtains following technique effect: uses this utility model not have the situation that dust flies upward everywhere, and wipes effective, after wiping, blackboard also can write as early as possible, not affect classroom progress。This utility model design is simple, easy to use, has broad application prospects。

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is described further。

As shown in Figure 1, 2, a kind of blackboard eraser, including handheld board 1 and cotton 2, also including expansion link 8, handle 9, there is press button 6 described handheld board side, charge port 7, there are water-storing box 5, dehydrator in inside, battery, cotton is fixed in handheld board, on the contact surface of handheld board and cotton, there is evenly distributed tiny holes, communicate with water-storing box, the handheld board back side, there are dehydrator air outlet 10 and water filling port 3, water filling port has lid 4。Post-drying machine air outlet opened by described press button has hot blast to produce by boasting。Water in water-storing box, it is possible to slowly penetrate on cotton via the tiny holes in handheld board front。Charge port can be used for charging to the battery in blackboard eraser。

Before using, beforehand through water filling port, inside blackboard eraser, fill water, cover lid, by blackboard eraser cotton place towards on put on the table。

Before wiping, swinging one's arm gently, the moisture of blackboard eraser storage inside can penetrate in cotton by the aperture between handheld board and cotton。

During wiping, owing to having sucked portion of water in cotton, dust will be pinned by moisture, will not fly away everywhere。And due to the dissolution of water, wiping effect also can improve。

Pressing the press button of handheld board side after wiping, dehydrator starts running and blows out hot blast, now pulls open expansion link, hand-held handle, and by handheld board towards the blackboard just nuzzled up, makes the hot blast of dehydrator blow to water stain place, so as to rapid evaporation。

When not using blackboard eraser, handheld board is downward, and cotton upwards, is placed on desk, it is prevented that water continues to flow out。

Blackboard eraser of the present invention, in using, does not have the situation that dust flies upward everywhere, and wipes effective, after wiping, blackboard also can write as early as possible, not affect classroom progress。
