[0032] The top and bottom of the inner wall of the plate placement groove 101a are both provided with a sliding track 101b, and a limiting groove 101b-1 is provided at the top of the outer wall of the sliding track 101b. First rotating pins 201a are provided at both ends of the outer wall of the connecting rod 201, and two groups of first rotating pins 201a are respectively provided at different planes. Rotating holes 202b are provided at the top and bottom of one end of the inner wall of the plate placement groove 101a and at the center of the top and bottom of the outer wall of the writing board 202. The two groups of first rotating pins 201a are respectively rotatably connected inside the rotating hole 202b provided on the inner wall of the plate placement groove 101a and inside the rotating hole 202b provided at the center of the outer wall of the second rotating pin 202a. A second rotating pin 202 is also provided at the top and bottom of one end of the outer wall of the writing board 202. a, two groups of second rotating pins 202a are respectively slidably connected inside the limiting groove 101b-1 of the sliding track 101b; through the above arrangement, the writing board 202 can be flipped along the sliding track 101b inside the board placement groove 101a. In the normal writing state, one end of the outer wall of the writing board 202 is parallel to the outer wall of the supporting frame 101. When the writing board 202 needs to be flipped, the writing board 202 is pushed. At this time, since the second rotating pin 202a at one end of the outer wall of the writing board 202 is slidably connected inside the limiting groove 101b-1 of the sliding track 101b, and the connection between the connecting rod 201, the writing board 202 and the supporting frame 101 enables the writing board 202 to flip during the sliding process.

[0033] The top of the support frame 101 is provided with a plurality of first connection holes 101a-1, and the bottom of the support frame 101 is provided with a second connection hole 101a-2. The first connection hole 101a-1 and the second connection hole 101a-2 are both connected to the plate slot 101a. A water tank 401a is provided inside the water tank 401. A plurality of air outlet pipes 401b and air inlet pipes 401c are alternately provided on the top of the outer wall of the water tank 401. The air outlet pipes 401b and the air inlet pipes 401c are connected to the water tank 401. a is internally connected, the air outlet pipe 401b and the air inlet pipe 401c are arranged vertically, several groups of air inlet pipes 401c pass through the second connecting hole 101a-2 of the supporting frame 101, and several groups of air outlet pipes 401b pass through the second connecting hole 101a-2 and the first connecting hole 101a-1; the function of the water tank 401 is to filter the air with a large dust content inside the board slot 101a when the erasing mechanism 300 wipes the writing board 202, thereby preventing the chalk dust from polluting the teaching environment after wiping.

[0034] A plurality of third connection holes 301b are formed through the top of the wiping plate 301, and a plurality of air outlet pipes 401b respectively penetrate the third connection holes 301b. The wiping plate 301 is slidably connected inside the plate placement groove 101a along the setting direction of the air outlet pipes 401b. The handwriting on the outer wall of the writing board 202 is rubbed and erased by the sliding wiping plate 301, and the air outlet pipes 401b also play a role in limiting the sliding of the wiping plate 301.

[0035] One end of the servo motor 302 is rotatably connected to a threaded rod 302a, and a screw hole 301a is penetrated through the top of the wiping plate 301. The inner wall of the screw hole 301a and the outer wall of the threaded rod 302a are both provided with threads, and the threaded rod 302a is threadedly connected to the inside of the screw hole 301a; the threaded rod 302a is threadedly connected to the inside of the screw hole 301a, so that the servo motor 302 can drive the wiping plate 301 to rise and fall through the threaded rod 302a.

[0036] A water inlet 401d is provided at one end of the outer wall of the water tank 401, and the highest point of the water tank 401 is not higher than the lowest point of the air outlet pipe 401b, and the lowest point of the water tank 401 is higher than the lowest point of the air inlet pipe 401c. Through this arrangement, the air inside the plate placement groove 101a can carry chalk dust into the filtrate inside the water tank 401a through the air inlet pipe 401c in the form of bubbles, and at the same time, the bubbles float up to increase the air pressure inside the water tank 401a, and the air inside the water tank 401a is discharged to the outside through the air outlet pipe 401b.

[0037] Both ends of the outer wall of the writing board 202 can be written on, and a circulation port is provided at the top of the board slot 101a. When the outer wall of the writing board 202 is parallel to and in contact with the outer wall of the supporting frame 101, the end of the board slot 101a away from the circulation port is combined with the wiping plate 301 so that the interlayer thereof is in a sealed state. When the writing board 202 slides down, the air inside the board slot 101a enters the board slot 101a through the circulation port, thereby maintaining the normal air pressure inside the board slot 101a.

[0038] Sealing patches are provided at both ends of the outer wall of the wiping plate 301, and the two ends of the outer wall of the wiping plate 301 are precisely fitted with the two ends of the inner wall of the plate placement groove 101a.

[0039] Working principle: In the normal writing state, since the slide track 101b limits the writing board 202, the writing board 202 will not deflect during normal writing. When the writing surface needs to be replaced, the writing board 202 is pushed so that the writing board 202 slides and flips along the slide track 101b at the board slot 101a, thereby replacing a new writing surface. When replacing the writing surface, the servo motor 302 rotates the threaded rod 302a, so that the wiping plate 301 located at the bottom of the board slot 101a slides in the board slot 101a along the direction of the air outlet pipe 401b. After the writing surface is replaced, since the writing board 202 is in contact with the support frame 101, the internal space of the board slot 101a is in a sealed state, and the servo motor 302 is controlled. The servo motor 302 rotates the threaded rod 302a through the threaded rod 302a drives the wiping plate 301 to slide down in the direction of the air outlet pipe 401b. During the sliding process of the wiping plate 301, the writing surface facing the inside of the plate placing groove 101a is wiped and cleaned. At the same time, since the internal space of the plate placing groove 101a is sealed, when the wiping plate 301 slides down, the air pressure inside the interlayer space formed by the bottom of the plate placing groove 101a and the wiping plate 301 increases, so that the air with chalk dust inside the interlayer enters the water storage tank 401a through the water storage tank 401 and is injected into the filtrate inside the water storage tank 401a in the form of bubbles. In this way, the chalk dust in the air is filtered. After the filtration is completed, the bubbles float up and burst, so that the air pressure inside the water storage tank 401a increases, and the filtered air is discharged through the air outlet pipe 401b.
