Fig. 2 is a schematic view of the internal structure of the circulating electrostatic dust-removing blackboard of the present invention.
Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1 and 2, a circulating electrostatic dust removing blackboard includes a housing 10, a support, a first roller 12, a second roller 13, a first motor 14, and a blackboard main body 15 of a flexible ring structure.
The support sets up inside shell 10, and shell 10 corresponds the support and has seted up show window 101, and first cylinder 12 and second cylinder 13 set up respectively in the support both sides, first cylinder 12 and first motor 14 fixed connection, and first cylinder 12 and second cylinder 13 surface are located respectively to blackboard main part 15 both ends cover, and blackboard main part 15 corresponds show window 101 and sets up. One side of the blackboard main body 15 is provided with a brush component, the brush component is used for wiping chalk marks on the surface of the blackboard main body 15, and one side of the brush component, which is far away from the blackboard main body 15, is provided with an electrostatic adsorption device 16.
One side of the blackboard main body 15 on the stand is displayed through the display window 101 on the housing 10, so that people can write on the blackboard main body 15. The first roller 12 is driven to rotate by the first motor 14, so that the blackboard main body 15 is driven between the first roller 12 and the second roller 13, the blackboard main body 15 is wiped on the surface by the brush component while the blackboard main body 15 is driven, and the purpose of removing the chalk on the blackboard main body 15 is achieved.
And when the brush component is used for wiping, the electrostatic adsorption device 16 arranged on one side of the brush component adsorbs dust in the wiping process, so that the situation that the dust is carried out in the air and flies is avoided. Through above-mentioned structure, can clean blackboard main part 15 automatically, avoid the manual condition of cleaning of people to appear, make things convenient for people to use to still adsorb the collection through electrostatic adsorption device 16 to the dust, also reduced the harm of dust to people's health.
There is the clearance between electrostatic adsorption device 16 and the brush subassembly, and electrostatic adsorption device 16 below is equipped with dust and collects box 17, avoids electrostatic adsorption device 16 and brush subassembly to contact, influences the normal operating of brush subassembly to collect box 17 through the dust and can collect the adsorbed dust of electrostatic adsorption device 16, the dust drops under the effect of gravity and collects in the box 17 to the dust.
In the scheme, the brush assembly comprises a brush roller 21 and a second motor 22, the brush roller 21 is in contact with the surface of the blackboard main body 15, the second motor 22 is in transmission connection with one end of the brush roller 21, and two ends of the brush roller 21 are in rotating connection with the support. The second motor 22 rotates the brush roller 21 so that the brush roller 21 is rotated simultaneously when the blackboard body 15 is driven between the first roller 12 and the second roller 13 to wipe the surface of the blackboard body 15.
And brush roller 21 quantity is one at least, and brush roller 21 all is connected with the transmission of second motor 22, in order to improve the effect of wiping of brush subassembly, can increase brush roller 21's quantity as required, and the mode of rethread transmission connection carries out the transmission with many brush rollers 21 and second motor 22 and is connected, makes second motor 22 drive many brush rollers 21 and rotates simultaneously, plays the purpose of wiping to blackboard main part 15 surface.
Be equipped with the backup pad 18 on the support is close to show window 101 one side, and the backup pad 18 area is more than or equal to show window 101 area, because blackboard main part 15 is flexible, so when people write vigorously, the sunken condition can appear, consequently, can write on blackboard main part 15 surface through backup pad 18 to people, plays the purpose of support.
The support is kept away from backup pad 18 one side and is equipped with the adjustment subassembly, and the adjustment subassembly is including promoting cylinder 31 and third cylinder 32, and third cylinder 32 both ends all are through promoting cylinder 31 and support fixed connection, and third cylinder 32 both ends all rotate with promoting cylinder 31 to be connected, and third cylinder 32 is located between first cylinder 12 and the second cylinder 13, and blackboard main body 15 contacts with third cylinder 32 surface.
Because the blackboard main body 15 is flexible, in the long-term use and transmission process, the blackboard main body 15 can be stretched and lengthened, the whole length of the blackboard main body 15 is lengthened, and the blackboard main body 15 is in a loose state between the first roller 12 and the second roller 13, so that the distance between the third roller 32 and the support can be pushed by the pushing cylinder 31, the blackboard main body 15 is far away from the support plate 18 and is in a V-shaped structure, the contact surface of the blackboard main body 15 and the support plate 18 is ensured to be in a flat state, and the service life of the blackboard main body 15 is prolonged.
