Embodiment Construction

[0013] see Figure 1 to Figure 3 , the embodiment of the present invention provides a whiteboard eraser 100 , which includes: a sponge pad 110 , a casing 120 , a driver 130 , a spray unit 140 and a control unit 150 .

[0014] The sponge pad 110 is disposed on the surface of the casing 120 . see figure 1 , the shape of the housing 120 is a cuboid, and the housing 120 has a first surface 121 and a second surface opposite to each other (not shown). In this embodiment, a groove 124 is formed at the center of the first surface 121. The groove 124 has a bottom surface 1241 parallel to the first surface 121. The bottom surface 1241 defines a spray hole 123. The spray hole 123 It is a round hole, and the groove 124 on the first surface 121 is used for accommodating the sponge pad 110 .

[0015] The spray unit 140 includes a container 141 , a spray nozzle 142 and a piston 143 , and the container 141 is used for containing cleaning agent. In this embodiment, the container 141 is a t...

Abstract

The invention discloses a whiteboard eraser. The whiteboard eraser comprises a sponge mat, a shell, a driver, an injecting unit and a control unit, wherein the sponge mat is arranged on a surface of the shell; the shell has an injecting hole; the injecting unit is interconnected with the driver, and is driven by the driver to inject cleaning solution to the sponge mat; the driver is interconnected with the control unit; the control unit comprises a pressure sensor and a chip; the pressure sensor is arranged on the shell; the chip is electrically connected with the pressure sensor; the pressure sensor is used for sensing the pressure suffered by the whiteboard eraser in wiping and converting the pressure to a pressure signal to send to the chip; and the chip is used for processing the signal received by the pressure sensor so as to control the driver to drive a piston to move a corresponding distance so as to control if the injecting unit injects the cleaning solution.

Description

technical field [0001] The invention relates to a whiteboard eraser capable of automatically spraying cleaning agent. Background technique [0002] In traditional teaching, chalk is used to write on the blackboard, and dust will fly when wiped with a blackboard eraser, which pollutes the teaching environment and affects the health of teachers and students. Nowadays, whiteboard markers are used to replace chalk teaching, and whiteboards are used to replace blackboards, followed by whiteboard erasers for wiping handwriting on whiteboards. [0003] The common whiteboard eraser is generally made of velveteen fabric, and the whiteboard is a white organic board. In the early stage of use, its wiping effect is better, but as the length of use increases, its wiping effect weakens, and the whiteboard eraser does not wipe clean. Thoroughness and other problems will follow, and the whiteboard will become stained due to the influence of the whiteboard eraser. Therefore, use a whiteboa...
