Embodiment
To make the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing to embodiment party of the present invention Formula is further described.
Fig. 1 is refer to, the embodiment provides a kind of dustless Rolling blackboard, including one flexible panel in a ring 1st, the transmission mechanism and two for being driven the flexible panel 1 are used for the sweeper 2 for cleaning the flexible panel 1, the biography Motivation structure forms with a driving wheel 3, the first driven pulley 4 and the second driven pulley 5, the driving wheel 3, the and of the first driven pulley 4 Second driven pulley 5 arranges in equilateral triangle shape, and the driving wheel 3 is driven by transmission belt 20 and the first driven pulley 4 and second Wheel 5 is connected to provide power, and the flexible panel 1 is sleeved on the driving wheel 3, the first driven pulley 4 and the second driven pulley 5, Face where between the axis of the axis of the driving wheel 3, the axis of the first driven pulley 4 and the second driven pulley 5 is by the flexible face Plate 1 divides for front panel, rear top panel and rear lower panel, and the driving wheel 3 is identical with the size of the first driven pulley 4 and its center line is equal In same vertical plane, the front panel for keeping flexible panel 1 is perpendicular, on rear side of the front panel of flexible panel 1 Provided with a vertical backing plate 6, the rear top panel and rear lower panel of flexible panel 1 carry the sweeper 2;
The backing plate 2 ensure that the experience write as normal blackboard, institute with the front panel of flexible panel 1 being vertically arranged State driving wheel 3 coordinates the first driven pulley 4 and the second driven pulley 5 to rotate to drive the rotation of flexible panel 1, just by transmission belt 20 Flexible panel 1 after writing can be driven to being cleaned at sweeper 2, eliminate the time of manual wipping;
It refer to shown in Fig. 2, it is opening to have cavity and rear and front end in the sweeper 2, and the flexible panel 1 passes through institute State and one is provided with the cavity of sweeper 2 and cavity above it cleans assembly, fixed at least two of the cleaning assembly rear and front end Vertical pole 7, each pole 7 between the top of sweeper 2 and cleaning assembly are cased with stage clip 8, the top of pole 7 outside A horizontal connecting plate 9 is fixed after through the top of sweeper 2 jointly, be additionally provided between connecting plate 9 and sweeper 2 top surface can on The expansion link 10 of lower movement.
It is above after can thus realizing because driving wheel 3, the first driven pulley 4 and the second driven pulley 5 are in triangular shape arrangement The inclined design of plate and rear lower panel, such sweeper 2 wipe to get up can more have dynamics, coordinate the downward pressure of stage clip 8, What is wiped is better, and if the content of writing on the blackboard is excessive, front panel record it is endless if, can also be lifted by expansion link 10 Connecting plate 9 overcomes the elastic force of stage clip 8 using pole 7 to rise cleaning assembly, such flexible panel 1 through sweeper 2 when Wait will not wiping panel, can also realize that rolling flexible panel shows more contents;
Further, the cleaning assembly includes a rectangle frame 11, and two are provided with side by side from front to back in the rectangle frame 11 The wiper 13 and one that individual rotatable Rolling brush 12, one is fixedly mounted rotatably rolls cloth brush 14, and the wiper 13 includes The water tank 131 of top and the mesh plate 132 of lower section, the side wall of water tank 131 are provided with the first hole for water spraying sprayed water to flexible panel 1 1311, bottom is provided with the second hole for water spraying 1312 sprayed water to mesh plate 132, and the bottom of mesh plate 132 is fixedly provided with for wiping Wipe the cleaning wiping cloth 133 of flexible panel 1, the rectangle frame 11 between two Rolling brushes 12 is fixedly provided with a sweep-up pipe 15, the suction The one end of dirt pipe 15 is sealed by rectangle frame 11, and the other end is provided with a connection aspirator after passing through rectangle frame 11 and the side wall of sweeper 2 Inlet scoop 16.
Further, described two Rolling brushes 12 rotation direction on the contrary, for by dust brush to sweep-up pipe 15, described two The top of sweeper 2 of the individual front and back of the Rolling brush 12 is fixedly provided with two vertical dust boards 17.
Dust board 17 effectively prevent there is airborne dust during Rolling brush 12 is cleared up, and forms an independent small sky Between, contribute to sweep-up pipe 15 to be absorbed into come as far as possible by dust, the rotation direction of two Rolling brushes 12 is on the contrary, and equal direction The direction of sweep-up pipe 15 is rotated, and so can be carried out preliminary pretreatment, and the dust kicked up is directly entered to sweep-up pipe 15, most Taken away eventually from the inlet scoop 16 of connection aspirator, the first hole for water spraying 1311 carries out water spray moistening to rear top panel/rear lower panel Cleaning wiping cloth 133 is moistened and rear top panel/rear lower panel is wiped by processing, rear second hole for water spraying 1312, such flexible panel 1 Surface treatment can be more clean, rolling cloth brush 14 then dries the moisture left, wiping it is better.
Further, the side wall of sweeper 2, which is provided with, is used for the chute 18 that sweep-up pipe 15 slides up and down.
The structure that sweep-up pipe 15 and rectangle frame 11 are fixed as one, it ensure that integrality when moving up and down, chute 18 Walking track is provided when being moved for sweep-up pipe 15.
Further, the top of the sweeper 2, which is provided with, is used to uncap 21 for water tank 131 plus water.
Uncap 21 it is convenient supplement water in time for water tank 131, ensure the effects wiped.
Further, a hair-dryer 19 is equipped with above and below the front panel of flexible panel 1, it is above with The air outlet of the hair-dryer 19 of side is respectively toward to the plate face of rear top panel and rear lower panel, make the wind of blowout along rear top panel and The plate face of lower panel is blown afterwards.
Further, the transmission mechanism, sweeper 2 and hair-dryer 19 are respectively positioned on rear side of the front panel of flexible panel 1 Sealing device 22 in.
Hair-dryer 19 carries out last moisture and air-dries processing, and the plate face for ensureing to enter front panel can be in drying all the time State, the writing of teacher not being influenceed, while can also being used as last one of barrier, the dust of any omission is blown back to front panel Rear, whole process are respectively positioned in the sealing device 22 on rear side of the front panel of flexible panel 1 and dustless effect are effectively ensured.
Specific embodiment described in the present invention is only to spirit explanation for example of the invention.Technology belonging to the present invention The technical staff in field can make various modifications or supplement to described specific embodiment or using similar mode Substitute, but without departing from the spiritual of the present invention or surmount scope defined in appended claims.
In the case where not conflicting, the feature in embodiment and embodiment herein-above set forth can be combined with each other.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all the present invention spirit and Within principle, any modification, equivalent substitution and improvements made etc., it should be included in the scope of the protection.
