The dust filter assembly includes an isolation plate 310 and an air passing square port 311 fixedly arranged on the isolation plate 310, an interception net 312 is fixedly arranged on the outer side of the air passing square port 311, a gas supply tee 37 is connected to the air passing square port 311, a dust collecting box 35 is clamped at the bottom of the front of the air collecting box 31, and the dust collecting box 35 is arranged opposite to the interception net 312, one end of the air collecting box 31 is fixedly connected to the first air pipe 33, a one-way valve 34 is fixedly installed in the middle of the first air pipe 33, the bottom end of the first air pipe 33 is fixedly connected to the perforated air box 11, and the wet wiping mechanism includes a cleaning plate 8 and a fixed The magnetic sliders 21 at both ends of the cleaning board 8 have connecting grooves 22 on their inner sides, and the connecting grooves 22 are slidably arranged on the sliding guide rails 5. A first Velcro 19 is fixedly arranged on the inner side of the cleaning board 8, and a second Velcro 20 is attached to the first Velcro 19, and a cleaning sponge 9 is fixedly arranged on the second Velcro 20, and the cleaning sponge 9 is in contact with the blackboard body 2. A wiping handle 10 is fixedly arranged on the front of the cleaning board 8, and the spray mechanism includes a square water pipe 17 and a plurality of water mist nozzles 18 fixedly installed at the bottom of the square water pipe 17, and the water mist nozzles 18 are arranged on the front of the cleaning board 8. The cleaning sponge 9 is provided with a water storage mechanism including a mounting block 12 and a cylindrical water bucket 6 fixedly mounted on the top of the mounting block 12, a water supply pump 15 and a water injection port 16 are fixedly mounted on the top of the cylindrical water bucket 6, a water outlet of the water supply pump 15 is fixedly connected with a water supply pipe 7, the top of the water supply pipe 7 is fixedly connected with a square water pipe 17, an observation port 14 is fixedly arranged on the front of the cylindrical water bucket 6, a control panel 13 is fixedly mounted on the front of the mounting block 12, a spray switch, a blow-dry switch and a dust suction switch are fixedly mounted on the surface of the control panel 13, and a storage table 4 is fixedly arranged on the bottom of the blackboard body 2;

[0024] During use, during the writing process, the airflow carries dust through the first air pipe 33 into the air collecting box 31. After the airflow passes through the interception net 312 to intercept the dust in the air, the airflow passes through the air outlet 311 into the air supply tee 37 and is finally discharged. The chalk dust accumulates at the interception net 312 and falls into the dust collecting box 35 under the action of gravity. The cleaning staff only needs to pull out the dust collecting box 35 regularly for cleaning. The function of the one-way valve 34 is to prevent the chalk intercepted in the air collecting box 31 from flowing back to the inside of the perforated air box 11 under the action of air pressure during blowing due to the high air flow rate in the perforated air box 11, so as to avoid the collected chalk dust being blown out. When wiping the blackboard body 2, the teacher can hold the wiping handle 10 and pull it down. At this time, the cleaning sponge 9 will move close to the surface of the blackboard body 2, and the surface of the blackboard body 2 can be wiped by the soaked cleaning sponge 9. The cleaning sponge 9 is attached to the cleaning plate 8 by Velcro, which is convenient for subsequent disassembly and cleaning. The cleaning plate 8 is slidably set on the sliding guide rail 5 through the magnetic sliders 21 at both ends. After the wiping handle 10 is released, the cleaning plate 8 is adsorbed and will not slide down. When the cleaning plate 8 is slid to the uppermost end of the sliding guide rail 5, the sliding guide rail 5 can be removed, which is convenient for cleaning and replacing the cleaning sponge 9. The blackboard is wiped efficiently and conveniently. The teacher can regularly add clean water to the cylindrical water bucket 6 through the water injection port 16. When wiping the blackboard, the water supply pump 15 is controlled to work by the spray switch. The water supply pump 15 sucks the water in the cylindrical water bucket 6 and fills it into the square water pipe 17 through the water supply pipe 7. The water mist nozzle 18 sprays water mist on the cleaning sponge 9 to soak the cleaning sponge 9, which is convenient for wiping the blackboard. Wet wiping can prevent chalk dust from floating, and the cleaning effect is also better.

[0025] When the embodiment of the present application is in use: the teacher can turn on the dust suction switch when writing, at this time, the fan group 38 is driven to work in the forward direction, and the air in the inlet and outlet air ducts 32 is continuously extracted. At the same time, only one of the two solenoid valves 39 is opened. When the dust suction switch is turned on, the solenoid valve 39 at the air port 311 is opened, and the solenoid valve 39 at the second air pipe 36 is closed. When the blow-drying switch is turned on, the two solenoid valves 39 are exchanged. Due to the continuous extraction of air, a negative pressure is generated in the perforated air box 11 through the first air pipe 33. Pressure is applied to the blackboard body 2, thereby sucking air around the blackboard body 2. The air enters the perforated air box 11 and rises, and finally enters the first air pipe 33, and then enters the air collecting box 31. After the airflow passes through the interception net 312 to intercept the dust in the air, the airflow enters the air supply tee 37 through the air square port 311, and is finally discharged. The chalk dust accumulates at the interception net 312, and falls into the dust collecting box 35 under the action of gravity. The cleaning staff only needs to pull out the dust collecting box 35 regularly for cleaning, which can improve the air quality near the podium.

[0026] After the blackboard is wiped, when the surface of the blackboard body 2 is wet, the teacher turns on the blow-drying switch, and at this time drives the fan group 38 to work in forward and reverse directions, introduces outside air through the inlet and outlet air ducts 32, and the air flow is diverted by the air supply tee 37, enters the second air duct 36, and finally enters the perforated wind box 11, blows air from the side of the blackboard body 2, accelerates the drying of the surface of the blackboard body 2, and turns off the blow-drying switch after drying.

[0027] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
