Abstract

The invention discloses a novel dust-suppressing blackboard eraser. The novel dust-suppressing blackboard eraser comprises a blackboard eraser shell, a water spraying component, a button, water spraying holes, a water filling hole and a hairbrush, wherein the hairbrush is fixedly arranged on the front end face of the blackboard eraser shell; the water spraying component is fixedly arranged in the blackboard eraser shell; the button is arranged at the upper top end of the left end face of the blackboard eraser shell; a plurality of water spraying holes are formed in the periphery of the blackboard eraser shell and are connected with a guide pipe of the water spraying component. On the premise of realizing the blackboard erasing effect of an existing blackboard eraser, the novel dust-suppressing blackboard eraser is also capable of realizing an effect that the dust on the blackboard is hard to fly in air when the blackboard eraser is used for erasing the blackboard by virtue of the water spraying component arranged inside the blackboard eraser, so the dust inhaled to a mouth and a nose of a person can be reduced, and harms to a human body are reduced; the novel dust-suppressing blackboard eraser is simple and novel in overall structure, high in practicability, wide in application range and easy to popularize and apply.

Description

technical field [0001] The invention relates to the technical field of blackboard eraser applications, in particular to a novel dust-suppressing blackboard eraser. Background technique [0002] A blackboard eraser is widely used in teaching. As a tool that can clean the writing on the blackboard, it has the advantages of small size and convenient use. [0003] But when people wipe the blackboard, the situation of dust flying is a common phenomenon, and inhalation is harmful to the human body. The present invention makes a blackboard eraser that can suppress dust, and then makes up for the deficiencies in the prior art. Contents of the invention [0004] The purpose of the invention is to provide a novel dust-suppressing blackboard eraser in order to overcome the deficiencies in the prior art. [0005] The present invention is realized through the following technical solutions: [0006] A novel dust-suppressing blackboard eraser, comprising a blackboard eraser shell, a wa...
