Abstract
An electronic projection scale comprises a scale body and a projection component arranged in the scale body for displaying the weighed weight onto a plane outside the scale body. Because the projection component is arranged in the scale body for displaying the weighed weight onto the plane outside the scale body, the weight of a weighed object can be projected out by the projection component during the weighing and displayed on planes like a front wall for a reader to read the weight conveniently, thereby completely coinciding with people's habit of looking forwards rather than looking downwards. Therefore, the weight can be read from the scale body or the numbers projected onto the external plane during the use, and people no longer need to read the numbers on the panel of the scale body through lowering the head or looking downwards. The projection scale has a reasonable structure, the numbers can be read directly and conveniently, and is convenient for all the people, particularly tall and fat persons to read the numbers. Moreover, the numbers projected by the projection component can be clearly displayed either in the daytime or at night, so that the projection scale is not limited by use time and environment, and the applicable rang is wide.
