Abstract

The invention discloses a blackboard eraser capable of removing accumulated dust. The blackboard eraser comprises a casing, an eraser belt, rotary barrels, rotary shafts, a support plate, an accumulated dust brush, a rear cover and a connecting component, wherein the casing is a cavity provided with an opening; a rear cover is arranged opposite to the opening and is connected to the cavity through the connecting component so as to shield the casing; a pair of rotary shafts are connected to the casing in parallel; the rotary barrels are respectively sleeved on the rotary shafts; the eraser belt is a closed soft belt which is sleeved on the two rotary barrels; after the eraser belt is sleeved on the two rotary barrels, a flat and straight segment at one side of the eraser belt extends out of the opening of the casing so as to brush a blackboard; the support plate is arranged between the two rotary barrels; two ends of the support plate are fixedly connected to the casing so as to support the flat and straight segment, extending out of the opening of the casing, of the casing; the brush body of the accumulated dust brush is fixed on the rear cover; the brush bristles of the accumulated dust brush are in contact with the flat and straight segment at the other side of the eraser belt. The blackboard eraser is used for brushing the blackboard by performing a lateral motion and used for removing the accumulated dust by performing a vertical motion. Thus, the blackboard eraser is convenient and practical and is capable of greatly reducing the dust pollution.

Description

Can remove eraser with dust collector
Technical field
The present invention relates to a kind of teaching aid, specifically a kind of blackboard eraser that can conveniently remove the wiper laying dust.
Background technology
Blackboard eraser is the indispensable instrument of teaching, but blackboard eraser can amass the very thick chalk dust of last layer on its felt-cloth after use a period of time, in the time of continuing to use, usually will look for a place to knock other object, shakes off laying dust.This occupation mode is very inconvenient, also easily causes dust pollution.Although the blackboard eraser design that much alleviates dust pollution is also arranged, and as Chinese patent literature, publication number is CN103213437A, CN102950943A, their most of designs, all for the brushing airborne dust, are not also removed the design of wiper laying dust.Chinese patent literature, the patent that publication number is CN101746194A, disclose a kind of by constantly changed the design of wiper by two rotating shaft cores, advantage is laying dust can be involved in to insert box to reduce chalk dust and fly upward, but weak point is the laying dust that this invention can not be removed wiper in time, need constantly to change wiper.
Summary of the invention
The objective of the invention is: for above problem, provide a kind of blackboard eraser that can conveniently remove laying dust.
Technical scheme of the present invention is: a kind of eraser with dust collector that removes, comprise housing, and wipe band, rotating cylinder, rotating shaft, fagging, laying dust brush, bonnet, connector.Described housing is a cavity, and cavity has an opening, on the opposite of opening, one bonnet is arranged, and bonnet is connected on cavity by described connector, covers housing.Have a pair of shaft parallel to be connected on described housing, described rotating cylinder is enclosed within respectively in this rotating shaft, and described wiping band is a closed soft band, is socketed on described two rotating cylinders, wipes the opening that stretches out housing with the flat segments of a side after socket, for the brushing blackboard.Be provided with a fagging between two rotating cylinders, the fagging two ends are fixedly connected on housing, stretch out the wiping band flat segments of shell nozzle for support.The brush body of described laying dust brush is fixed on bonnet, and laying dust brush bristle is with the flat segments contact of wiping with opposite side.
The invention has the beneficial effects as follows: the transverse movement erasing blackboard, move up and down except laying dust, convenient and practical, greatly alleviate dust pollution.
The accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is A-A cutaway view of the present invention.
Fig. 3 is B-B cutaway view of the present invention.
Fig. 4 is C-C cutaway view of the present invention.
In Fig. 1, Fig. 2, Fig. 3, Fig. 4: 1. housing, the 1a. opening, 2. wipe band, and 2a. wipes and is with a side flat segments, and 2b. wipes band opposite side flat segments, 3. rotating cylinder, 4. rotating shaft, 5. fagging, 6. laying dust brush, 6a. bristle, 6b. brush body, 7. bonnet, 8. connector.
Below in conjunction with drawings and Examples, the present invention is further described.
the specific embodiment:
Housing 1 is a cavity, and cavity has an opening, and a bonnet 7 is arranged on the opposite of opening, and bonnet 7 is connected on cavity by connector 8, covers housing 1.Have that a countershaft 4 is parallel to be connected on housing 1, in rotating shaft 4 respectively cover rotating cylinder 3 is arranged, wipe and be with 2 to be a closed felt band, be socketed on two rotating cylinders 3, wipe the opening 1a that stretches out housing 1 with the flat segments 2a of 2 one sides after socket, for the brushing blackboard.Be provided with a fagging 5 between two rotating cylinders 3, fagging 5 two ends are fixedly connected on housing 1, for supporting the flat segments 2a wiped with 2 one sides.Laying dust brush 6 is comprised of brush body 6b and bristle 6a, and brush body 6b is fixedly connected on bonnet, and bristle 6a is with the flat segments 2b contact of wiping with 2 opposite sides.
The course of work of the present invention: during the brushing blackboard, blackboard eraser is vertically held, and the brushing process is transverse movement, wipes and to be subject to the axially identical of force direction and rotating cylinder 3 with 2, therefore wipes and is with 2 can, around 3 rotations of two rotating cylinders, not affect brushing.When wiping is with 2 laying dusts to thicken, blackboard eraser moves up and down, now, wiping is subject to force direction identical with the circumferencial direction of rotating cylinder 3 with 2, makes to wipe to be with 2 to rotate around two rotating cylinders 3, in wiping, is with in 2 rotation processes, laying dust is brought in housing 1, brushed off by laying dust brush 6, fall in the blackboard eraser cavity.When the laying dust that brush falls in cavity increases, can open connector 8, take off bonnet 7, pour out laying dust and clear up laying dust brush 6.Operating process is easy, and, owing to being to brush laying dust in housing, has greatly alleviated dust pollution.
