Abstract

The invention discloses a multifunctional dual-step dual-precision electronic scale. The multifunctional dual-step dual-precision electronic scale comprises a loading plate, a first precision weighing module with a first supporting surface, a second precision weighing module with a second supporting surface and an elastic pad support. In a free state, the second supporting surface is lower than the first supporting surface, and the second supporting surface supports the whole electronic scale alone. When the loading plate carries an object, the stressed loading plate presses the elastic pad support and drives the first supporting surface to move down. When the weight of the carried object exceeds a certain level, the first supporting surface moves down to support the whole electronic scale with the second supporting surface. The multifunctional dual-step dual-precision electronic scale provided by the invention can be used as a weight electronic scale and a kitchen electronic scale, and can effectively prevent the kitchen electronic scale from being damaged when the weight of the carried object exceeds the maximum scale of the kitchen electronic scale.
