Embodiment Construction
[0008] figure 1 The chalk dust scattered downward from the blackboard body 1 will enter the interior of the box body 2 through the suction hole 3 on the top cover of the box body 2. At this time, there is an appropriate amount of water inside the box body 2 to absorb the entered chalk dust. , so that the scattered chalk dust is collected and fixed. When cleaning, open the piston of the water outlet hole 5 on the side of the box body 2, and the sewage with chalk dust will flow out of the box body 2 downward along the slope 4 at the bottom of the box, and catch the sewage with a sewage bucket at the water outlet hole 5 , when you use it again, just replace it with clean water from the suction hole 3.

The invention provides a dust collection blackboard rack which comprises a rectangular box body parallel to the lower edge of a blackboard body, the box body is used for storing a proper amount of water, a small hole is formed in the top of the box body, a water outlet hole is formed in the side surface of the box body, and the inner bottom surface of the box body is an inclined surface. The chalk dust is absorbed by water when entering the box body through the small hole in the top of the box body, so that the chalk dust is effectively fixed. A piston of the water outlet hole on the side surface is opened when the dust collection blackboard rack is cleaned, the waste water with the chalk dust flows out of the water outlet hole along the inclined surface at the bottom of the box body, the waste water flowing out is received, and the device can be reused after clean water is changed through the small hole in the top.
Description
technical field [0001] The invention relates to a blackboard frame, in particular to a dust suction type blackboard frame. Background technique [0002] The traditional blackboard stand is a sheet parallel to the bottom of the blackboard, used to catch the chalk dust scattered downward when people write with chalk and wipe the blackboard. There are many hygienic dead ends in the building. And it has no top cover, chalk dust will be blown into the air and cause air pollution, which is bad for health. Contents of the invention [0003] The invention provides a dust-absorbing blackboard frame, which can not only receive chalk dust scattered downward during the process of people writing with chalk and wiping the blackboard, but also the collected chalk dust is easy to clean. [0004] The technical scheme adopted by the present invention is: a rectangular box is placed in parallel along the lower edge of the blackboard, and the top of the box is opened to facilitate the entry...
