Abstract
The utility model provides a dust suction type blackboard eraser, which is provided with a blackboard eraser. The bottom plate of the blackboard eraser is provided with a plurality of groups of brush hair, a plurality of through holes are arranged on the bottom plate of the blackboard eraser, the blackboard eraser adopts a hollow cavity type, a supporting plate is installed at the middle part of the hollow cavity of the blackboard eraser, a fan is installed on an open hole at the middle position of the supporting plate, a battery bin is installed on the side wall above the supporting plate, the fan is connected with the power supply of the battery bin through a power wire, a switch is installed on the side wall of the blackboard eraser and connected with the power wire through a conducting line, a cover is arranged on the battery bin, the cover is mutually buckled with the top plate of the blackboard eraser, and air holes are arranged on the top plate. Because the blackboard eraser adopts the suction force of the fan to absorb the dust, the noise is low, because the fan is fixed on the supporting plate, the vibration damping effect is good, and the dust suction type blackboard eraser has the advantages of simple structure, good dust adsorption effect, convenient dust removal, and strong practicability.
Description
Technical field
The utility model relates to school supply and stationery, is specifically related to a kind of ash-collecting blackboard eraser.
Background technology
In the middle of daily teaching, often need on blackboard, write the content of courses, original written contents to be wiped with traditional blackboard eraser, but the problem that exists is, when blackboard eraser is wiped the letter written with chalk on the blackboard, produce a large amount of dust from flying, the dust that flies upward drop on the person's of erasing the board arm and on one's body, not only pollute environment in the classroom, and have a strong impact on the healthy of teachers and students in the classroom.Disclosed technology has electrodynamic type blackboard eraser and dust-free black board eraser, because its complex structure, poor practicability can't be promoted the use of.
Summary of the invention
The purpose of this utility model provides a kind of ash-collecting blackboard eraser, and it adopts the suction adsorption dust of fan effective, and it is convenient to remove dust, has characteristics simple in structure, practical.
The purpose of this utility model realizes by following scheme: ash-collecting blackboard eraser, it has blackboard eraser, the blackboard eraser base plate is provided with the array bristle, the blackboard eraser base plate is provided with several through holes, blackboard eraser is a cavity type, at blackboard eraser cavity middle part gripper shoe is installed, the perforate of gripper shoe center is equipped with fan, battery compartment is installed on sidewall above the gripper shoe, fan is connected with the power supply of battery compartment by power line, and switch is installed on the blackboard eraser sidewall and is connected with power line by lead, and described battery compartment is provided with lid, lid is interlocked with the top board of blackboard eraser, and is provided with pore on top board.On the blackboard eraser sidewall, be provided with obstruction.
The beneficial effects of the utility model are: owing to adopt the suction dust suction of fan, noise is little, and fan is fixed on the gripper shoe, and good damping result has simple in structurely, and the absorption dust is effective, and it is convenient to remove dust, practical advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Ash-collecting blackboard eraser of the present utility model, it has blackboard eraser 13, blackboard eraser 13 base plates 4 are provided with array bristle 6, and blackboard eraser 13 base plates 4 are provided with several through holes 5, and blackboard eraser 13 is a cavity type, middle part at blackboard eraser 13 cavitys is equipped with gripper shoe 1, gripper shoe 1 center perforate is equipped with fan 2, because fan 2 is fixed on the gripper shoe 1, stability is strong when using the utility model, not vibration sense, safety and stability.On the described gripper shoe 1 top sidewall battery compartment 10 is installed,, is prolonged the service life of battery compartment 10 owing to there is gripper shoe 1 that dust and battery compartment 10 are separated.Described fan 2 is connected with the power supply of battery compartment 10 by power line 3, switch 8 is installed on blackboard eraser 13 sidewalls 9 and is connected with power line 3 by lead, described battery compartment 10 is provided with and covers 11, and lid 11 is interlocked with the top board 12 of blackboard eraser 13, and is provided with pore on top board 12.The obstruction 7 that described blackboard eraser 13 sidewalls are provided with is used to remove the dust in the cavity, is rubber owing to stop up 7, thus increased stop up 7 and blackboard eraser 13 sidewalls between sealing.When the utility model uses, press switch 8 and make fan 2 energising rotations, the through hole 5 of dust on the blackboard eraser base plate that when the bristle on the blackboard eraser 13 6 rubs on blackboard back and forth, produces by the cavity of fan 2 inspiration blackboard erasers in, dust in needs will enter blackboard eraser 13 cavitys will stop up 7 when removing and extract, can clean out, it is effective to have an absorption dust, and it is convenient to remove dust, advantage simple in structure, practical.
The utility model not detailed description is a known technology.
