Description

Blackboard eraser with cleaning watering can

Technical Field

The utility model relates to a teaching aid, especially a clean watering can blackboard eraser.

Background

The eraser of the traditional blackboard and whiteboard mainly comprises a shell for holding by hand and a cotton eraser for erasing, wherein the cotton eraser is fixed on the shell. The blackboard eraser adopts a dry erasing mode, so that dust flies when the blackboard eraser is used for erasing a board, which is not beneficial to environmental protection and health, and the blackboard eraser cannot be erased cleanly after being used for a long time; the white board eraser has good effect when erasing the white class which has just written characters, but the white board eraser needs to be stained with water or cleaning solution to ensure the cleaning effect when the board surface is too long in airing time, and the operation is troublesome.

In view of the above situation, the chinese utility model patent, entitled CN2834939Y, discloses a water spraying blackboard eraser, which has a body movably sleeved on an extended surface of a watering can, a gap convenient for holding is left in the middle of the kettle body, the kettle body and a pneumatic nozzle are hermetically connected with a bottle cap and a pneumatic nozzle connecting pipe, and a wrench is arranged.

Although the water-spraying blackboard eraser combines the functions of the blackboard eraser and the watering can, the eraser body is movably sleeved on the kettle body, a handheld gap is reserved in the middle of the kettle body, the cleaning solution can be repeatedly filled in the kettle body, and the kettle body can be repeatedly used, thereby reducing the cost and avoiding pollution.

However, the holding gap of the water spraying blackboard eraser makes the whole kettle body in a shape like a Chinese character 'kou', the operation is inconvenient when the water spraying blackboard eraser is held for spraying water, the water spraying blackboard eraser does not accord with the design of ergonomics and aesthetics, the eraser body is movably sleeved on one surface of the extension of the kettle body, the eraser body is troublesome when being fixed, and the risk of falling off exists when the whiteboard is erased.

SUMMERY OF THE UTILITY MODEL
