Abstract
The utility model discloses a water storage type blackboard eraser, which comprises a water storage device and sponge. A control tab is arranged between the water storage device and the sponge; four water outlets (A) are formed on the bottom part of the water storage device; four water outlets (B) are formed on the control tab; the water outlets (a) and the water outlets (B) overlap up and down when the control tab is moved; a water injection switch is arranged at the top of the water storage device; a pull ring (A) is arranged on the water injection switch; and a pull ring (B) is arranged on the control tab. When the blackboard eraser is used, if the sponge needs to be wetted, all that is needed is to pull the pull ring (B) on the control tab to move the control tab and enable the water outlets (A) and the water outlets (B) to overlap, so that water can flow into the sponge from the water storage device to achieve the effect of wetting the sponge. When the blackboard eraser is not used, the control tab is moved so that the water outlets (A) and the water outlets (B) are staggered and water can not flow out. Since the water injection switch is arranged at the top of the water storage device, the pull ring (A) on the water injection switch is pulled to turn on the water injection switch so as to inject water into the water storage device.
Description
Technical field
The utility model designs a kind of blackboard eraser, relates in particular to a kind of storage water heater blackboard eraser.
