Description
Technical field
The utility model belongs to the instructional technology field, and is particularly a kind of simple in structure, easy to use, can remove the dust-removing blackboard eraser of chalk dust in use.
Background technology
Blackboard is the essential articles for use of classroom instruction, and its is for academics and students writing and teaching data, can be divided into traditional chalk writing blackboard and water-color paintbrush writing blackboard according to the difference of writing medium.Because the content of courses is more, the area of blackboard is limited, therefore must constantly use blackboard eraser to wipe writing on the blackboard in use.The most of schools of China are employed to be traditional blackboard, because traditional blackboard adopts chalk as writing medium, when blackboard wiping, not only waste time and energy like this, but also can cause dancing in the air all over the sky of chalk dust, had a strong impact on academics and students's health and academics and students's study mood.At present, the blackboard eraser of some dedustings is arranged also on the market, but all exist defectives such as complex structure, use inconvenience and dust removing effects difference.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of simple in structure, easy to use, can remove the dust-removing blackboard eraser of chalk dust in use.
The purpose of this utility model is achieved in that a kind of dust-removing blackboard eraser, the wiper that comprises the blackboard eraser main body and be arranged on blackboard eraser main body one side, described blackboard eraser main body is hollow structure, the inside of blackboard eraser main body is provided with dust removing tube, the face that described blackboard eraser main body contacts with wiper is provided with air suction opening, the face of the blackboard eraser main body at air suction opening place is provided with the collecting hood that shrouds all air suction openings, collecting hood is communicated with an end of dust removing tube, and the other end of dust removing tube is communicated with dust absorption fan.
The inside of described blackboard eraser main body also arranges the power supply that promising dust absorption fan provides electric power, and described power supply is lithium battery or dry cell.
The arranged outside of described wiper has the limit cover that is fixed on the blackboard eraser main body, and the height of described limit cover is less than the thickness of wiper.
Be filled with wet sponge in the described dust removing tube.
Described dedusting hole evenly distributes on blackboard eraser main body and face that wiper contacts.
Be provided with switch between described dust absorption fan and the power supply, described switch is arranged on the another side of blackboard eraser main body, and described switch is inductive switch.
The utlity model has following positive effect: the utility model is under the situation of the shape that does not change original blackboard eraser and size, in the inside of blackboard eraser main body dust absorption fan and dust removing tube are set, have simple in structure, be convenient to implement and promote the advantage that can remove chalk dust in use; Dust removing tube is set is used for dedusting, fill wet sponge in the dust removing tube, compare with existing blackboard eraser with dedusting function like this, dust removing effects of the present utility model is better; Adopt lithium battery or dry cell to use, carry and deposit conveniently as power supply; The arranged outside limit cover of wiper has increased the capacity gauge to chalk dust, makes the better effects if of dedusting; Adopt inductive switch between dust absorption fan and the power supply, use more convenient like this.
Description of drawings
Fig. 1 is the structural representation of a kind of dust-removing blackboard eraser of the utility model.
Fig. 2 is the vertical view of Fig. 1.
Among the figure: 1, blackboard eraser main body 2, wiper 3, air suction opening 4, collecting hood 5, dust removing tube 6, dust absorption fan 7, wet sponge 8, switch 9, power supply 10, limit cover.
The specific embodiment
Below in conjunction with drawings and Examples the utility model is described in detail.
As depicted in figs. 1 and 2, a kind of dust-removing blackboard eraser, the wiper 2 that comprises blackboard eraser main body 1 and be arranged on blackboard eraser main body 1 one side, described blackboard eraser main body 1 is hollow structure, the inside of blackboard eraser main body 1 is provided with dust removing tube 5, the face that described blackboard eraser main body 1 contacts with wiper 2 is provided with air suction opening 3, the face of the blackboard eraser main body 1 at air suction opening 3 places is provided with the collecting hood 4 that shrouds all air suction openings 3, collecting hood 4 is communicated with an end of dust removing tube 5, and the other end of dust removing tube 5 is communicated with dust absorption fan 6.
The inside of described blackboard eraser main body 1 also arranges the power supply 9 that promising dust absorption fan 6 provides electric power, and described power supply 9 is lithium battery or dry cell.
The arranged outside of described wiper 2 has the limit cover 10 that is fixed on the blackboard eraser main body 1, and the height of described limit cover 10 is less than the thickness of wiper 2.
Be filled with wet sponge 7 in the described dust removing tube 5.
Described dedusting hole 3 evenly distributes on blackboard eraser main body 1 and face that wiper 2 contacts.
Be provided with switch 8 between described dust absorption fan 6 and the power supply 9, described switch 8 is arranged on the another side of blackboard eraser main body 1, and described switch 8 is inductive switch.
The utility model in use, open dust absorption fan, the chalk dust that blackboard eraser produces in wiping process is by in air suction opening and the collecting hood inspiration blackboard eraser main body, chalk dust is removed in dust removing tube, the dust absorption fan gas of producing by boasting just can not carry chalk dust like this, and then played the purpose of removing chalk dust, avoided the random problem that flies to endanger academics and students's health and mood of chalk dust that causes because of blackboard wiping.The utility model arranges dust absorption fan and dust removing tube in the inside of blackboard eraser main body under the situation of the shape that does not change original blackboard eraser and size, have simple in structure, be convenient to implement and promote the advantage that can remove chalk dust in use; Dust removing tube is set is used for dedusting, fill wet sponge in the dust removing tube, compare with existing blackboard eraser with dedusting function like this, dust removing effects of the present utility model is better; Adopt lithium battery or dry cell to use, carry and deposit conveniently as power supply; The arranged outside limit cover of wiper has increased the capacity gauge to chalk dust, makes the better effects if of dedusting; Adopt inductive switch between dust absorption fan and the power supply, use more convenient like this.
