Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
The utility model provides one kind and changes face automatic-cleaning backboard, as shown in Figure 1, including fixed frame 1 and can be embedding
Enter the blackboard 2 in fixed frame 1；1 symmetrical two inside of fixed frame is equipped with guide rail 3, and idler wheel 4 is embedded in each guide rail 3, black
2 top both ends of plate are connect by shaft with idler wheel 4；Blackboard 2 is equipped with mobile blackboard eraser 5, and mobile blackboard eraser 5 is close to 2 face of blackboard.
As shown in Fig. 2, being installed with motor 6 at the top of fixed frame 1, motor 6 connects one end of lead screw 7, silk by shaft coupling
The other end of thick stick 7 is installed in 1 bottom of fixed frame；Mobile blackboard eraser 5 is equipped with ball nut 8, and ball nut 8 and 7 shape of lead screw
At ball screw assembly,.As shown in Figure 1, the side wall of fixed frame 1 is equipped with switch 13, which is connect by conducting wire with motor 6.
Start motor 6, drive ball screw assembly, mobile blackboard eraser 5 is driven to work.
As shown in figure 3, mobile blackboard eraser 5 includes matrix 51 and the cleaning part 52 with 51 one of matrix, the bottom of matrix 51 is set
There is nozzle 53, as shown in figure 4, nozzle 53 connects the water outlet of water pump by outlet pipe 54；The water inlet of water pump connects water inlet pipe
55 one end, the other end of water inlet pipe 55 protrude into the bottom of fixed frame 1.The bottom of fixed frame 1 offers chevron groove 56,
The other end of water inlet pipe 55 protrudes into the pocket of chevron groove 56；When in use, the pocket of chevron groove 56 is equipped with water, water inlet
The water surface of 56 pocket of chevron groove is immersed in the end of pipe 55, and water pump is drawn water out of chevron groove 56 by water inlet pipe 55, passed through
Outlet pipe 54 send water to nozzle 53, and water is sprayed to 2 face of blackboard to be wiped by nozzle 53, the blackboard 2 that then mobile blackboard eraser 5 will squirt
It wipes clean, the water of ejection flows back in 1 bottom chevron groove 56 of fixed frame along 2 plate face of blackboard.
The water surface of 56 pocket of chevron groove is immersed in the end of water inlet pipe 55, and is not inserted into the pocket bottom of chevron groove 56
Portion, first is that avoiding suction hose 55 from sucking the sewage for cleaning blackboard 2, second is that chalk dust particle can slowly be deposited to chevron groove
56 bottoms, and the water phase of 56 water surface of chevron groove is to limpid.
As shown in figure 3, nozzle 53 is equipped with multiple, and the equal length of the length of nozzle 53 and mobile blackboard eraser 5.Mobile blackboard eraser
5 length is equal with the width of blackboard 2；When in use, as the movement of mobile blackboard eraser 5 is to entire 2 spraying-rinsing of blackboard.Nozzle
It is directed toward the wiping surface of blackboard 2 at an angle in 53 spout direction.
As shown in figure 4, chevron groove 56 is equipped with discharge outlet 57, and discharge outlet 57 is equipped with the water blockoff plug 58 to match；Work as mountain
Connected in star 56 used it is multiple it is messy after, water blockoff plug 58 is extracted, the sewage in chevron groove 56 is discharged by discharge outlet 57, weight
New replacement clean water.
As shown in Figure 1, Figure 2 and shown in Fig. 5, the bottom two sides of blackboard 2 is mounted on handle 9, when the setting of handle 9 is in order to overturn
It is laborsaving convenient.
As shown in Fig. 1 and 6, barrier rib 10 is equipped in guide rail 3, and barrier rib 10 is magnetic strips.Barrier rib 10 is selected, so that
Blackboard 2 is easy to be returned to use state after overturning, and Convenient blackboard 2 positions.The length direction of barrier rib 10 is parallel to the length of guide rail 3
Spend direction, when blackboard 2 overturning after be returned to vertical position or the position parallel with the length direction of guide rail 3 when, 2 two sides of blackboard with
Fixed frame 2 is bonded, so that blackboard 2 be prevented to continue around the rotation of its shaft, realizes positioning, and easy to use.
The two sides that blackboard 2 is in contact with guide rail 3 are equipped with magnetic strips 11.Magnetic strips 11 are used cooperatively with barrier rib 10, so that
Blackboard 2 is stronger when being bonded with fixed frame 1, is close to, and improves the reliability changed during face, prevents blackboard 2 in rotation
Stablize and rotate down around the shaft because losing, causes security risk, injure user by a crashing object.
As shown in Figure 1, fixed frame 1 is installed with guide post 12, and the guide post 12 passes through the mobile blackboard eraser 5.Guide post is set
12 prevent mobile blackboard eraser 5 at work around the axis rotation of lead screw 7.
A kind of workflow for changing face automatic-cleaning backboard of the utility model:
Blackboard 2 is moved up by handle 9, blackboard 2 is moved on guides 3 by idler wheel 4, and blackboard 2 can be on fixed frame 1
Overturning movement, so that blackboard 2 is embedded into fixed frame 1, blackboard 2 can change face use.It is embedded into fixation after the overturning of blackboard 2
Frame 1, pump working, the water spray of nozzle 53 squirt blackboard 2；At this point, the plate face of blackboard 2 to be erased is in closed state, open
Dynamic motor 6 drives ball screw assembly, and mobile blackboard eraser 5 is driven to work, and the length of mobile blackboard eraser 5 can cover the width of entire blackboard 2
Degree；Mobile blackboard eraser 5 wipes the writing of 2 plate face of blackboard, and chalk dust is slowly settled, will not be flown upward everywhere.
By the above-mentioned means, the utility model changes face automatic-cleaning backboard, by idler wheel 4 and guide rail 3, so that blackboard 2
It is dynamic transfer can be turned in fixed frame 1, and blackboard 2 is embedded into fixed frame 1；Blackboard 2 can change face use.When blackboard 2
It is embedded into fixed frame 1, starts water pump, blackboard 2 is squirted cleaning by the water spray of nozzle 53, so that the erasing of 2 plate face of blackboard is more dry
It is net and do not have dust.Start motor 6, drive ball screw assembly, mobile blackboard eraser 5 is driven to work, the writing of 2 plate face of blackboard is automatic
Erasing；One side to be erased is in sealing space, erase the board 2 when do not have a dust from flying, erasing plate face environmental protection is clean, beneficial to strong
Health.
