At present, the white board becomes an important erasable tool for most of teaching, meeting, family record and the like. The existing market white board eraser with various shapes and colors is divided into two categories: white board eraser without spray and white board eraser with spray.
The whiteboard eraser without spraying has simple structure and low price, but is not ideal when erasing the writing which is dried for a long time and often cannot completely erase the marks on the whiteboard. If the mark on the white board is to be completely erased, a wet rag or a spray can is needed to be manually used for wetting the surface of the white board, and then the white board is used for wiping, so that the wiping process is very inconvenient, and the writing efficiency of a user is influenced.
The white board eraser with spray can spray the liquid stored in the white board eraser onto the white board before wiping, and then wiping is carried out. Thus, the erasing effect on the writing which is already dried for a long time can be good. However, the amount of water sprayed by the existing whiteboard eraser on the market is not easy to control, and excessive spraying is easily caused during spraying, so that after the whiteboard eraser is used for erasing, too much liquid still remains on the whiteboard and is not dried, and sometimes even too much liquid is sprayed to leave a trace of water drop flowing on the whiteboard, thereby influencing the user to write on the whiteboard again.

Examples effects and effects
According to the whiteboard eraser of the embodiment, the liquid is atomized into 1-5 μm of tiny fog particles by using the ultrasonic atomizer and then sprayed out of the whiteboard, so that the liquid particles sprayed on the whiteboard are finer, and a user can easily erase the writing on the whiteboard. Meanwhile, the amount of the liquid sprayed by atomization is small, and large water drops can not be formed on the white board, so that the phenomenon that the water drops flow on the white board is avoided.
According to the whiteboard eraser of this embodiment, use button switch to let the user can last to press button switch when needs atomized liquid to control atomizer work, control atomizer stop work immediately after loosening button switch, make the atomizing blowout of user ability convenient and fast's control whiteboard eraser interior liquid through the mode of this kind of inching.
According to the white board eraser of the embodiment, the erasing surface is divided into two areas by the design of the U-shaped erasing surface, so that when the white board eraser is used for erasing after liquid is atomized and sprayed out, the same area on the white board is sequentially erased twice, and the cleaning effect of the white board eraser is improved.
According to the whiteboard eraser of the embodiment, the detachable water tank is utilized, so that a user only needs to detach the water tank when adding liquid to the whiteboard eraser, and the whole whiteboard eraser, namely the U-shaped eraser surface, is prevented from being wetted when filling the water tank with the liquid.
According to the whiteboard eraser of the embodiment, the charging interface is a USB charging interface with the rated voltage of 5V, and is consistent with the interface of the low-voltage charging household equipment commonly used in the market at present, so that a user can charge the whiteboard by using a 5V charger at will without additionally arranging the charging equipment.
According to the whiteboard eraser of this embodiment, because the existence of pilot lamp, make the user can judge the charged state of lithium cell in the whiteboard eraser through the light and dark of pilot lamp, and after the discovery pilot lamp goes out, in time stop charging when charging finishes promptly, whether the atomizer in the whiteboard eraser is in the on-state with the power according to the difference of pilot lamp colour simultaneously, thereby judge the liquid in the retaining mechanism and be consumed up when the atomizer is no longer atomized liquid but the pilot lamp lights the blue light, thereby immediately, add the liquid that is used for atomizing.
According to the whiteboard eraser of the embodiment, when the distance between the whiteboard eraser and the whiteboard is smaller than the preset minimum distance, the proximity switch is used for controlling the power supply circuit to be switched off, so that the atomizer is controlled to stop working. The phenomenon that excessive liquid is remained on the white board and even a trace of water drop flowing is left on the white board due to the fact that the humidifying liquid is atomized when the distance between the white board eraser and the white board is too close is avoided, and therefore the phenomenon that the user writes on the white board again is avoided.
The above embodiments are merely illustrative of specific embodiments of the present invention, and the whiteboard eraser is not limited to the scope of the above embodiments.
