Detailed Description
The invention is described in further detail below with reference to the figures and the specific embodiments.
The protection device of the intelligent blackboard shown in fig. 1 to 5 comprises a guide rail 1, a sliding frame, a static removing rod 5 and a dust suction device; the guide rails 1 are arranged at the side ends of the intelligent blackboard 15, two guide rails 1 are arranged in the embodiment and are respectively horizontally arranged at the upper end and the lower end of the intelligent blackboard 15, and actually, the guide rails 1 can also be arranged at the left side and the right side of the intelligent blackboard 15; the sliding frame is arranged on the guide rail 1 and is in sliding fit with the guide rail 1; the static eliminating rod 5 and the dust suction device are respectively arranged on the sliding frame; the dust suction device comprises a blower 6, a dust suction opening 7 and a dust collection box 8; the dust collection port 7 is horn-shaped and is provided with a large head end and a small head end, the large head end of the dust collection port 7 is arranged opposite to the static removing rod 5, and the small head end of the dust collection port 7 is communicated with an air inlet of the blower 6; the dust collecting box 8 is arranged at the air outlet of the blower 6, an air outlet 9 is arranged on the dust collecting box 8, and filter cotton 10 is arranged at the position, located at the air outlet 9, of the dust collecting box 8. The static eliminating rod 5 of the embodiment adopts the existing finished product. After the static electricity removing rod 5 removes the static electricity on the intelligent blackboard 15, the dust suction port 7 sucks the tiny dust on the intelligent blackboard 15 into the dust collection box 8 for storage.
