Abstract

The invention discloses a dust-suction blackboard which comprises a blackboard body with variable background colors. The blackboard body comprises a blackboard main body; clamping grooves are formed in the two upper edges of the back surface of the blackboard body in the length direction of the blackboard body; and a colored background plate is detachably connected in the clamping grooves. Due tothe fact that the clamping grooves are formed in the two upper edges of the back surface of the blackboard body in the length direction of the blackboard body and the colored background plate is detachably connected in the clamping grooves, people can conveniently detach the background plate and replace the background plate with background plates of other colors, and the functions that the colorscan be changed as required and the teaching process has entertainment are achieved.

Description

technical field [0001] The invention relates to a teaching device, in particular to a blackboard with a variable background color.
