Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in figs. 1 and 3, full automatic environmental protection type blackboard eraser, comprises framework 15, motor 10, screw rod 2, nut 8, blackboard eraser 14, flip cover assembly and water tank mechanism; Water tank mechanism comprises outlet pipe 3, travel switch 4, water tank 5, water pump 6, sewage collecting pipe 7 and filter membrane 22; Framework 15 is fixed on wall, and framework 15 is provided with flip cover assembly; Two screw rod 2 horizontal positioned, and be bearing on framework 15 by bearing one on the other; Elastic washer 13 is fixed on screw rod, to the bearing axial limiting on screw rod; Two nuts 8 form screw thread pair with a screw rod 2 respectively, and weld with one end of blackboard eraser 14 respectively; Two screw rods 2 are all fixed with belt wheel 12, and the base of motor 10 is fixed on framework 15, and its output shaft is connected by shaft coupling 9 with a belt wheel 12; Two belt wheels 12 are connected by Timing Belt 11; Water tank 5 is separated into clean hydroecium 20 and sewage collecting room 21 by filter membrane 22; The bottom of outlet pipe 3 is communicated with by water pump 6 with clean hydroecium 20, and water distributor 25 bottom in top and blackboard eraser 14 is in sustained height; The bottom of sewage collecting pipe 7 communicates with sewage collecting room 21, and top communicates with the sump bottom framework 15; Travel switch 4 is fixed on framework 15, and is connected with water pump 6, controls the keying of water pump 6; When blackboard eraser 14 is in high order end, touch travel switch 4, thus start water pump 6.
As shown in Figure 2, flip cover assembly comprise renovate 1, extension spring 16, connecting rod 17, thimble 18 and slide block 19; Renovate 1 middle part and framework 15 hinged; Two slide blocks 19 form sliding pair with the guide rod being arranged on framework 15 both sides, and hinged with one end of a connecting rod 17 respectively; The other end of two connecting rods 17 is hinged on the both sides, lower end of framework 15; One end of two extension springs 16 is all fixed on wall, and the other end connects the both sides, lower end of renovating 1; The inner side of two slide blocks 19 is all fixed with thimble 18.When blackboard eraser 14 moves to thimble 18 position, blackboard eraser shell 23 promotes thimble 18, and is acted on by connecting rod 17, renovates 1 and is covered by blackboard eraser, and now extension spring 16 is in extended state; When blackboard eraser moves right, extension spring 16 extended state is slowly removed, and will renovate 1 and open, blackboard eraser continues to move right, and carries out the motion that erases the board.
As shown in Figure 4 and Figure 5, blackboard eraser 14 is made up of blackboard eraser shell 23, sponge 24 and water distributor 25; The two ends of blackboard eraser shell 23 are welded with two nuts 8; Sponge 24 is cemented on blackboard eraser shell, and water distributor 25 is embedded in sponge 24; The tube wall of water distributor 25 offers multiple water distributing pore group vertically, and each water distributing pore group comprises circumferential multiple water distributing pore; When water distributor 25 moves to water tank mechanism position with blackboard eraser 14 and aims at outlet pipe 3, blackboard eraser 14 triggers travel switch 4, water pump 6 by the water in clean hydroecium 20 in outlet pipe 3 spirt water distributor 25, and penetrated in sponge 24 by the water distributing pore of water distributor 25 tube wall, thus play the effect of cleaning blackboard eraser.
The operation principle of this full automatic environmental protection type device for blackboard eraser:
During initial position, blackboard eraser is positioned at blackboard high order end, now renovates 1 and covers blackboard eraser 14.Actuating motor 10, motor 10 drives two screw rod 2 synchronous axial system by Timing Belt 11 and two belt wheels 12, blackboard eraser 14 is moved right, namely starts to carry out the motion that erases the board; Now, blackboard eraser shell 23 is gradually away from thimble 18, and cover renovating of blackboard and 1 to open under the restoring force effect of two extension springs 16 thereupon, when blackboard eraser 14 moves to blackboard low order end, motor 10 reverses, and blackboard eraser 14 is to left movement.When blackboard eraser 14 moves to high order end, renovate 1 toilet cover and live blackboard eraser, the outlet pipe 3 in water tank 5 aimed at by water distributor 25 now in blackboard eraser, and blackboard eraser shell 23 triggers travel switch 4, water pump 6 is opened and the water in clean hydroecium 20 is entered water distributor 25 by outlet pipe 3, the water distributing pore of water distributor 25 tube wall is sprayed water to blackboard eraser, the sponge 24 of cleaning blackboard eraser; Water after cleaning flows into the sump bottom framework 15, and the sewage collecting collecting water tank 5 eventually through sewage collecting pipe 7 is indoor, and the water of sewage collecting indoor can realize sewage purification through filter membrane and recycle.
