Description
Technical field
The utility model belongs to teaching aid field, relates to a kind of chalkboard eraser, particularly a kind of chalkboard eraser that reclaims chalk dust.
Background technology
In the education activities of school, still use in a large number at present chalk.When using chalkboard eraser to wipe, chalk dust can enter air, harm surrounding environment.It is healthy that Faculty and Students suck chalk dust meeting serious threat, and therefore many teachers suffer from PUD D.
Although there is the product of multiple absorption chalk dust now, all there is complex structure, volume is larger, defect with high costs.The general school particularly ma'am school of the shortage of capital cannot therefrom benefit, and vast country school is badly in need of addressing this problem, to protect the healthy and safe of Faculty and Students.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, and volume is little, with low cost, and can reclaim the chalkboard eraser of chalk dust.
To achieve these goals, the technical scheme that the utility model is taked is:
The chalkboard eraser of described recovery chalk dust, comprise wiping board body and hairbrush, described wiping board body is provided with switch, air outlet and is positioned at the air suction opening of described wiping board body the same face with described hairbrush, in described wiping board body, be provided with dust absorption passage, described dust absorption passage is communicated with described air suction opening and described air outlet, is provided with storage dirt bag and dust exhaust apparatus in described dust absorption passage.
Described wiping board body is simultaneously being provided with solar power current collection plate without described hairbrush, the battery of the power supply of described dust exhaust apparatus for charging by described solar power current collection plate, and described battery is located in described wiping board body.
Described wiping board body side surface is provided with the dust pour spout that is communicated with described storage dirt bag, and described dust pour spout is provided with closed cover.
Described wiping board body has the one side of described hairbrush to be provided with the projection that there is cavity inside, and described air suction opening is positioned on described projection, through described cavity, is communicated with described dust absorption passage; Described projection is less than described hairbrush with respect to the height of described wiping board surface with respect to the height of described wiping board surface.
Described wiping board body has the one side of described hairbrush to be provided with nonwoven rubbing head.
Described wiping board body has the one side of described hairbrush to be provided with nonwoven rubbing head slot and elastic clip, and described nonwoven rubbing head is plugged on described nonwoven rubbing head slot, by described elastic clip, is fixedly clamped.
Adopt technique scheme, not only can in clean erasing out handwriting, reclaim chalk dust, and simple in structure, and cost is low.Using solar energy as the energy, economize on electricity environmental protection.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation that reclaims the chalkboard eraser of chalk dust of the utility model;
Fig. 2 is the front view of structure shown in Fig. 1;
Fig. 3 is that structure shown in Fig. 1 is except the structural representation of horizontal rotary turnback after brush for removing fuzzy fibre.
Being labeled as in figure:
1, wiping board body; 2, hairbrush; 3, solar power current collection plate; 4, air outlet; 5, nonwoven rubbing head; 6, dust pour spout; 7, projection; 8, elastic clip; 9, dust absorption passage; 10, battery; 11, dust exhaust apparatus; 12, storage dirt bag; 13, air suction opening; 14, switch.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail, to help those skilled in the art to have more complete, accurate and deep understanding to inventive concept of the present utility model, technical scheme.
As shown in Figure 1 to Figure 3, the utility model provides a kind of chalkboard eraser that reclaims chalk dust.The wiping board body 1 that comprises hollow.Battery 10, dust exhaust apparatus 11 and storage dirt bag 12 are housed in wiping board body 1.Wiping board body 1 one side is equipped with hairbrush 2, and solar power current collection plate 3 is housed in the one side with this surface opposite, for powering to battery 10.
At wiping board body 1, be equipped with on the same face of hairbrush 2 and be also provided with projection 7 and nonwoven rubbing head 5, the two lays respectively at the both sides of hairbrush 2.Projection 7 is fixed on wiping board body 1, and it is highly less than hairbrush 2 height.Projection 7 has air suction opening 13, and air suction opening 13 passes into its inner dust absorption passage 9.Dust absorption passage 9 is communicated with dust exhaust apparatus 11 and the storage dirt bag 12 in wiping board body 1, and finally by the air outlet 4 on wiping board body 1, is in communication with the outside.5 of nonwoven rubbing heads are plugged in the nonwoven rubbing head slot on wiping board body 1, fixing by the elastic clip 8 being contained on wiping board body 1, open elastic clip 8 and can change nonwoven rubbing head 5.
Storage dirt bag 12 is made by filtering material, and the air that contains dust is by storing up after dirt bag 12, and dust is left in storage dirt bag 12.In a side of wiping board body 1, be provided with a dust pour spout 6 that is communicated with described storage dirt bag 12, this dust pour spout 6 can be closed.In the side contrary with this face, be provided with switch 14, for controlling dust exhaust apparatus 11.
When using this chalkboard eraser, hairbrush 2 is attached on blackboard after opening switch 14, below projection 7 is placed in, move down removing writing.The most of whereabouts of chalk dust that hairbrush 2 brushes off, and the projection 7 that is positioned at below is through air suction opening 13 absorptions.And the vestige that the nonwoven rubbing head 5 of top stays after hairbrush 2 can being removed is wiped clean simultaneously.Under the effect of dust exhaust apparatus 11, chalk dust is stored up dirt bag 12 and is filtered down, and air is discharged by air outlet 4.Prevent flying upward of chalk dust, protected the healthy of Faculty and Students.
When storage dirt bag 12 approaching filling, pick-up performance declines, and dust pour spout 6 is opened, and in collection bag, pours chalk dust into, and these dust can be used further to manufacture chalk, have saved material.Before using, answer closed dust pour spout 6, prevent the dust ejection sucking.During without this chalkboard eraser, with solar energy collector plate 3, towards the mode of sunlight, be placed on bright place, solar radiation provides the energy for it, economize on electricity environmental protection.
By reference to the accompanying drawings the utility model has been carried out to exemplary description above; obviously the concrete realization of the utility model is not subject to the restrictions described above; as long as the various improvement that adopted method design of the present utility model and technical scheme to carry out; or directly apply to other occasions without improvement, all in protection domain of the present utility model.
