Description
Technical field
The present invention relates to classroom articles for use fields, and in particular to a kind of cleaning chalkboard eraser.
Background technology
During teacher impart knowledge to students and gives lessons, blackboard can be used to carry out classroom instruction with chalk.It is wiped in chalk writing
It just needs to use chalkboard eraser when wiping, but will produce a large amount of dust, dust from flying can make the health of student and teacher
It is problematic.Chalk dust can stimulate schneiderian membrane, be extremely harmful for those for the teachers and students of dust allergy, and can be into
One step induces breathing problem.
Further, since the model of blackboard and chalk and with the difference and environment temperature of material and the influence of humidity, the wiping of dust
It wipes effect and also will produce difference.If with the excessively soft chalkboard eraser of material, it is not easy to wipe letter written with chalk, if material is really up to the mark, again
A degree of damage can be caused to blackboard surface.
Invention content
The object of the present invention is to provide a kind of cleaning chalkboard erasers, can effectively absorb the dust of generation, avoid a large amount of dust
It flies upward in air, and is selected for user equipped with the different rub body of soft or hard degree, improve cleaning efficiency.
The present invention above-mentioned technical purpose technical scheme is that：A kind of cleaning chalkboard eraser, including
It ontology and setting and is used to wipe the rub body of dust on the body, which is characterized in that the rub body includes hard rub body and soft rub body,
The hard rub body includes multiple hard wiping pipes, and the soft rub body includes multiple soft wiping pipes, and the soft length for wiping pipe is more than described hard
Wipe the length of pipe；Also include to be arranged dust cover on the body and set the suction powder dress for being used to collect dust on the body
It sets；Powder output slot is offered on described body sidewall, the device for inhaling powdery substances includes the storage powder that is located at and in the powder output slot and can skid off
Box, the wind wheel in the storing powder box, the powder leakage hole for setting appearance powder mouth on the body and being opened on the appearance powder mouth.
Rub body on the ontology does both ends formula design, is that hard wiping pipe and the hardness of hardness bigger are smaller respectively, more soft
The soft material for wiping both pipe of sum can be different, in addition, the length setting of the two is also different, wherein the soft length for wiping pipe
Degree can be longer.The purpose being arranged in this way uses the design concept of " two-part pressure adjusts wiping ", is commonly wiping
Under state, the longer soft wiping pipe and blackboard contact avoid the hard wiping pipe and blackboard contact from scratching blackboard.It is needing one
When under a little hard objects extensions, user can hold the ontology, tilt or firmly press, the soft wiping pipe deforms upon generation
It shrinks, and the hard wiping pipe is contacted with blackboard.In such a mode, the hard wiping pipe and the soft wiping Guan Douyu blackboards contact,
Wipe out more firm trace.
During blackboard wiping, a large amount of dust will produce.The wind wheel is moved built-in such as button cell
Power component is rotated by, and generates suction, dust is entered by the powder leakage hole in the storing powder box.The storing powder box
It can be slided in the powder output slot, after use, user can take out the storing powder box, clean the storing powder box.
As a preference of the present invention, it is described hold powder mouth include be obliquely installed draw powder inclined-plane, the powder inclined-plane that draws is to described
Body interior tilts, and multiple powder leakage holes are opened in described draw on powder inclined-plane.
The inclined design drawn powder inclined-plane and specially done is not grudged and described draws between powder inclined-plane and the ontology that there are a slopes
Degree is poor, this algebraic difference between adjacent gradients can play the role of the dust of suspension one blocking, especially hold the ontology black in user
When movement on plate, under this algebraic difference between adjacent gradients keeps off dust in moving process, dust is collected by the powder leakage hole.
As a preference of the present invention, the soft wiping pipe is comprising elastic tube and is located on the elastic tube, bore is more than described
The buffer cap of elastic tube.
As a preference of the present invention, also including to be equipped with use with the soft button cloth wiped pipe and be detachably connected, the button cloth
It is buckled in the catching groove on the buffer cap in set.
Elastic material can be used in the buffer cap, and bore is big, and on the one hand the contact with blackboard is more soft, on the other hand,
The design of the hat shape of the elastic tube and the buffer cap allows the oral area to be fixed on the soft wiping pipe, so that institute
It is detachable to state button cloth.
As a preference of the present invention, also including cleaning device, the cleaning device includes the water for being located at the chamber body
Box, for the water inlet to the water box water filling and the water outlet piece for spilling water, the water outlet piece is set on the body,
The button for controlling watering is additionally provided on the ontology.
As a preference of the present invention, the water outlet piece is multiple, each water outlet piece includes pedestal, is cut with scissors with the pedestal
The rotation pipe connect, multiple rotation pipes are commonly connected on joining beam.
When user presses the button, the water in the water box is sprayed by the water outlet piece.User can draw
The dynamic joining beam altogether, to adjust the angle of the rotation pipe, to adjust water spray angle.
As a preference of the present invention, also including auxiliary dry device, the auxiliary dry device includes connection on the body and can adjust
The adjusting bracket of length is located at the shaft that can be rotated on the adjusting bracket and the wiping cylinder being set in the shaft.
User adjusts the height and position of the wiping cylinder by adjusting the adjusting bracket.It is discharged when the water outlet piece sprays
Afterwards, the wiping cylinder rolls on blackboard, dries water mark.
As a preference of the present invention, the dust cover includes to be socketed in the socket part of described body sidewall in frame-type and be located at
On the socket part, extend to body width direction both sides, arc-shaped outer arc portion, is equipped with and is used between two outer arc portions
It is operated to wrist and the wrist in space is provided leaves a blank area.
As a preference of the present invention, the soft wiping pipe is connected on the body by flexible connecting member, the flexibility is even
Fitting includes the soft column being connect with the ontology, the bulb for being located at the soft column end, is set in the bulb and can opposite institute
The connecting plate stated the link block of bulb rotation and be connected on the link block, the multiple soft wiping pipe are located at the connecting plate.
As a preference of the present invention, the soft rub body is between the hard rub body and the auxiliary dry device 7.
In conclusion the present invention has the advantages that：
1. the soft or hard two-piece design of rub body, convenient for adjusting wiping effect
2, be equipped with cleaning device, can under the operation of user automatic outletting, and angle of water is flexibly adjustable.
3, wind wheel generates suction, and dust is entered storing powder box by powder leakage hole, convenient for absorbing dust, is conducive to cleaning.
4, the dust cover is detachably arranged on the body, further strengthens dust-proof effect.
