Further, the sweep-up pipe is equipped with the suction inlet of flat, the width of the suction inlet and the width of felt belt It is identical.
Further, be equipped on the cylinder outer wall of motor cooperation installation it is several uniformly distributed for limiting roller and felt The opposite lug boss slided of band.
Further, the lug boss is cone or hemisphere or cylinder.
Further, the height of the lug boss is 2~5mm.
Further, the support plate being bonded with felt belt is equipped between two rollers of brush body opening.
Further, several uniformly distributed support bars are transversely provided in the felt belt.
The beneficial effects of the utility model are:
By the felt belt for being changed to drive by roller by the felt item of traditional insertion blackboard brush bottom, in erasing blackboard When, felt belt outside brush body erases the board, and when felt belt occupies many chalk dusts, blackboard brush is just difficult to blackboard at this time It wipes clean, by motor roller is driven to rotate so that felt belt moves, and is arrived so as to brush in vivo cleaner felt belt drive Outside brush body, so that erasing blackboard obtains blackboard eraser cleaner, and when felt belt moves, scraper plate is to the powder in felt belt Dirt scrapes, and dust is drawn into dust-collecting box by sweep-up pipe, so that felt belt becomes clean, is cycled successively, so that Blackboard brush obtains blackboard brush cleaner, also greatly reduce dust.
Description of the drawings
Fig. 1 is the structure chart of blackboard brush;
Fig. 2 is the sectional view of felt belt.
It is marked in figure:1 it is brush body, 2 be roller, 21 be lug boss, 3 be felt belt, 31 be support bar, 4 is sweep-up pipe, 41 It is motor for suction inlet, 5,6 be scraper plate, 7 be dust-collecting box, 8 be impeller, 9 be exhaust pipe, 10 be dust filter unit, 11 is support plate.
Specific embodiment
The utility model is described in detail below in conjunction with the accompanying drawings.
Such as Fig. 1~blackboard brush shown in Fig. 2,1, four roller 2 of box-like brush body and felt belt 3 including bottom opening, institute Two in roller 2 both sides being installed in parallel in respectively in brush body 1 are stated, other two roller 2 is separately mounted to the opening of brush body 1 Position, end to end felt belt 3 are wrapped in the outside of four rollers 2, and two rollers 2 being open mounted on brush body 1 are so that portion Felt belt 3 is divided to be located at the outside of box-like brush body 1, and the opening of the outer felt band 3 and box-like brush body 1 positioned at box-like brush body 1 Parallel, four rollers 2 so that felt belt 3 is tightened, with the cooperation of motor 5 install, and passes through electricity by inside brush body 1 a roller 2 Machine 5 drives the roller 2, and motor 5 is connected with power supply, and power supply is the lithium battery 12 in brush body 1, and motor 5 is equipped with controller, from And motor 5 can be controlled to rotate, so as to which felt belt 3 be controlled to be driven;It is equipped with to siphon away 3 outer surface of felt belt in the brush body 1 The sweep-up pipe 4 of upper dust, the sweep-up pipe 4 are connected with dust-collecting box 7, be equipped in sweep-up pipe 4 for by air-flow from 4 mouthfuls of sweep-up pipe The impeller 8 being transported in dust-collecting box 7, impeller 8 are equipped with driving device, are preferably electro-motor, are connected on the dust-collecting box 7 logical Exhaust pipe 9 outside toward brush body 1, the outlet of the exhaust pipe 9 is equipped with dust filter unit 10, so that the chalk after erasing the board In grey most of dust-collecting box 7 all in brush body 1, the scraper plate 6 contacted with 3 outer surface of felt belt is installed in brush body 1, it is described Scraper plate 6 is arranged on rear end of 4 suction inlet of sweep-up pipe along 3 moving direction of felt belt, so as to avoid being leaked out by the dust that scraper plate 6 scrapes; The top of brush body 1 is equipped with openable and closable folding lid, convenient for the dust in dust-collecting box 7 is poured out.
The sweep-up pipe 4 is equipped with the suction inlet 41 of flat, the width of the suction inlet 41 and the width phase of felt belt 3 Together, the chalk dust in felt belt 3 can be siphoned away, dust suction scope is bigger, also can suction inlet 41 be set to infundibulate in addition.
Be equipped on 2 outer wall of roller of the cooperation installation of motor 5 it is several uniformly distributed for limiting roller 2 and 3 phase of felt belt To the lug boss 21 of slip, the lug boss 21 is cone or hemisphere or cylinder, the height of the lug boss 21 for 2~ 5mm, best, the height of lug boss 21 is 3mm, and it is relatively sliding with felt belt 3 can to avoid or limit roller 2 by lug boss 21 It is dynamic.The support plate 11 being bonded with felt belt 3 is equipped between two rollers 2 being open mounted on brush body 1, passes through support plate when erasing the board 11 enable to felt belt 3 that can wipe cleaner with blackboard contact area bigger.It is transversely provided in the felt belt 3 several Uniformly distributed support bar 31, support bar 31 can be plastic material, by the support bar 31 being equipped with felt belt 3 be enabled to locate always In the state of extension, felt belt 3 is avoided to be shunk from 2 both sides of roller so that felt belt 3 smoothes out.
