Water flow cleaning type blackboard

Abstract

The invention discloses a water-flow cleaning type blackboard, which comprises a board surface, guide rails are installed on the left and right sides of the board surface, a blackboard eraser device is installed above the guide rail, and a controller is installed on the right side of the guide rail. A water storage tank is installed above the board surface, and a water pump is installed inside the water storage tank, and the lower surface wall of the water storage tank is provided with a water spray port, and a screen is installed below the board surface, and a screen is installed under the screen. A sump is installed. Compared with the traditional blackboard, the water-cleaning blackboard is equipped with a water storage tank and a water spray port above the board surface to spray water on the chalk characters on the surface of the board surface, which is convenient for wiping with a cloth, and at the same time avoids chalk characters due to Wipe and the dust flies. By installing a dry erase box and a wet erase box in the blackboard eraser, different operations can be performed on the blackboard to ensure that the blackboard is cleaner. Through the buckle installed on the right surface wall of the wet wiping box, the wiping cloth can be taken out for cleaning to ensure the cleanliness of the blackboard.

Description

technical field [0001] The invention relates to the technical field of blackboard cleaning, in particular to a water flow cleaning type blackboard. Background technique [0002] Blackboards have been widely used nowadays, and their shapes and structures have become more diverse. However, in work and study, the most commonly used is the mutual sliding of two blackboards, which can be relative sliding up and down, or mutual sliding between left and right. However, as the volume and number of blackboards become larger and more, the cleaning of blackboards has gradually become an annoying thing for people. Chalk writing will drop a lot of dust when it is wiped off. Teachers teach in a dusty environment, and students study in a dusty environment. Long-term inhalation of dust will cause harm to human health. When the surface of the blackboard eraser is not clean, a large amount of dust will be left on the surface of the blackboard after the blackboard eraser wipes the chalk chara...

Sliding, but as the volume and number of blackboards become larger and more, the cleaning of blackboards has gradually become a troublesome thing for people

Chalk characters will drop a lot of dust when they are wiped off. Teachers teach in a dusty environment, and students study in a dusty environment. Long-term inhalation of dust will cause harm to human health

When the surface of the blackboard eraser is not clean, a large amount of dust will be left on the surface of the blackboard after the blackboard eraser wipes the chalk characters, which cannot achieve the purpose of effectively cleaning the blackboard
