Description
Technical field
The utility model relates to a kind of attending classes articles for use blackboard eraser, suit especially to be used for teaching in all kinds of schools, or enterprises and institutions is used in the Dust-absorbing regular eraser that uses on the publicity board hurdle.
Background technology
The patent No. 00249215.6 " electronic guiding suction type dust suction blackboard eraser " is though also provide a kind of dust-absorbing rate high blackboard eraser, and it also needs often transposing battery, and it adopts bristle to wipe ash, and cleaning effect is affected.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of Dust-absorbing regular eraser is provided, and dust-absorbing rate height not only, and cleaning effect is better, uses more convenient.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: Dust-absorbing regular eraser is installed in the housing of belt switch by the motor of band fan blade, and housing fuses with forward and backward lid respectively, and with have the brush board of putting dirt lid, cover plate, bristle, air channel and battery and connect into whole the composition, the motor of described band fan blade also is connected with guard, also has the ash collection slot that communicates with dust pocket on the brush board on the described brush board inwall.
Compared with prior art, advantage of the present utility model is: the air channel that horizontal stroke, straight longer path are arranged on the brush board of this brush, and the air channel is other bristle that larger area made by wool felt and many ash collection slots on the inwall are arranged, but the large tracts of land view picture is cleared up the dust on the blackboard fast when therefore using, so the dust-absorbing rate height, cleaning effect is better.Make power supply with rechargeable battery again and use, it is at once chargeable to use up the back, therefore uses more convenient.Indicator lamp is bright when working simultaneously, and working signal is arranged, and the time spent can not turned off power supply, reduce the waste of forgetting that the pass switch brings, and the motor of band fan blade is completely enclosed within guard and the housing, does not contact with dust, make motor rotation light, and prolonged the service life of motor.

The specific embodiment
Embodiment is further described the utility model below in conjunction with accompanying drawing:
Protecgulum (1) is the two sides opening, and circumferential edges has the cavity of seam and buckle (4), and the circular arc muscle of protrusion is arranged in the middle of the two side, and two long protruding buttons are arranged on the sidewall lower limb.
Bonnet (13) is the two sides opening, and circumferential edges has the cavity of seam, and the rear wall upper end has grid, lower end that one jack is arranged, and has the circular arc muscle of protrusion and the coupling on the protecgulum (1), a sidewall lower limb that two long protruding buttons are arranged in the middle of the two side.
Housing (9) is a forward and backward two sides opening, periphery has seam and grab, and the cavity of large and small through hole is arranged on the end face, and the ante-chamber opening is little in the cavity, the back cavity opening is big, the centre is a motor cavity, and the rear end of motor cavity is divided into upper and lower two chambeies that communicate again and epicoele and ante-chamber are obstructed.
Dust absorption net (3) is big end down truncated rectangular pyramids shape grid cavity, and its outer surface is coated with dust suction cloth or is with guard (2).
Brush board (17) on the rectangle in horizontal stroke, straight irregular elongated hole air channel is arranged, and bonding is fixed the erose bristle of being made by wool felt (16) on the outer surface on limit, air channel (20), on the inner wall surface, many the groove dust collecting troughs (18) that have dust stratification dirt to use, and the rectangular recess dust pocket (15) that an end margin has the repertory dust to use, one cover plate (14) is arranged on its inner surface, outer surface has one movably to put dirt lid (19), and edges at two ends has the through hole that cooperates with forward and backward lid (1), the long protruding button of (13) sidewall lower limb.
Motor cavity in housing (9) is put into the motor (7) of band fan blade (6), and between upper and lower chamber the terminal box of connecting band insulation board (11).
An end that connects switch (8), indicator lamp (10) in the large and small through hole on housing (9) end face, and end is connected with terminal box in addition.
The housing (9) that assembles is screwed on brush board (17), and leave a distance between brush board (17) and be dust channel, the rechargeable battery (12) that has socket (21) is placed on the cover plate (14), its lead-out wire is connected with terminal box, and be close to the dust suction network interface (5) of being with through hole at fan blade (6) end face, tight then cover is with the guard (2) of dust absorption net (3), before inciting somebody to action at last, bonnet (1), (13) connect into integral body with seam on it and buckle (4) with housing (9) respectively, and with before, bonnet (1), be mated in the through hole at long protruding button insertion brush board (17) two ends, two (13) and connect into integral body, Dust-absorbing regular eraser is assembled into.
