Abstract
A dustproof blackboard eraser comprises a device shell, wherein a handle is arranged at the upper part of the device shell; a water tank is arranged in the device shell; and a brush is arranged at the lower part of the device shell. According to the dustproof blackboard eraser, water is leaked onto the brush by pushing a water baffle, and thus the brushed can be wet. Accordingly, chalk ash can be effectively prevented from splashing in a blackboard cleaning process, less chalk ash is breathed by teachers and students, and not only the teaching environment but also the physical health of teachers and students are guaranteed.

Detailed description of the invention
As Figure 1-3, a kind of dust-proof blackboard eraser, including device case 1, the top of described device case 1 is provided with handle
2, described device case 1 is provided with water tank 3, described water tank 3 top is connected with tank lid 4, and described water tank 3 bottom is opened
It is provided with one group of water outlet of water tank 5, is provided with water fender 6 in the middle part of described device case 1, described water fender 6 offers one group
Through hole 7, described through hole 7 is adaptive with described water outlet of water tank 5, and described water fender 6 one end is provided with push rod 8, described device
Housing 1 is provided with one group of spring 9, the upper end of described spring 9 and mounting blocks 10 on described water fender 6 lower surface correspondence position
Fixing connection, the top of described mounting blocks 10 is provided with one group of roller 11, described roller 11 and the following table of described water fender 6
Face contact coordinates, and the bottom of described device case 1 is provided with hairbrush 12.
Offering mounting groove 13 in the middle part of described device case 1, described water fender 6 is arranged in described mounting groove 13 and with described
Mounting groove 13 is slidably matched, and described mounting groove 13 connects with crossing water square hole 14.
Offering one group of spring groove 15 on described mounting groove 13 lower surface, described spring 9 is arranged in described spring groove 15.
It is outside that described device case 1 is stretched out in described push rod 8 one end, and described push rod 8 stretches out the end outside described device case 1
It is provided with and pushes away cap 17.
Described water tank 3 top is provided with water-filling nozzle 16, and described water-filling nozzle 16 is spirally connected with described tank lid 4.
When using this to have the dust-proof blackboard eraser of water tank, user can turn on tank lid 4, by water-filling nozzle 16 to water tank 3
In fill water, then tank lid 4 is screwed on, is provided with water outlet of water tank 5 bottom water tank 3, but water outlet of water tank 5 is adopted
The water fender 6 made with quality of rubber materials blocks so that water can not spill, water fender 6 under the impetus of spring 9, energy
