[0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale.
However, the existing kitchen electronic scales have an accuracy of 1 gram or even less, but their range generally does not exceed 10 kilograms, so they cannot be used as weighing scales.
For users, if they need to carry both of them out, it will take up a lot of space

The invention discloses a dual-purpose combined electronic scale comprising a first precision electronic scale and a second precision electronic scale. The first precision electronic scale consists of a first carrying plate and first precision weighing assemblies for weighing an object carried by the first carrying plate; the second precision electronic scale includes a second carrying plate and second precision weighing assemblies for weighing an object carried by the second carrying plate; the second precision electronic scale is arranged right below the first carrying plate; all second support legs are arranged on the bottom wall of the first carrying plate; and the second carrying plate is higher than the bottom walls of all first support legs. Limiting elements having sliding cavities are arranged on the bottom wall of the first carrying plate; and the tops of all second support legs are arranged in the sliding cavities and can move up and down along the sliding cavities. Static contacts are arranged on the limiting elements; moving contacts are arranged on the second support legs; and when the moving contacts move up and down with the second support legs, connection or disconnected with the static contact can be realized. The dual-purpose combined electronic scale has high portability.
Description
technical field [0001] The invention belongs to the technical field of electronic balance structure design. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment button, a power module and a load cell for supporting the loading board. When the weight of the loaded object exceeds the preset value, the display screen will start to display the value. The preset value is generally 5 kg; in addition, the maximum range of this kind of weight electronic scale is generally 180 kg, and the accuracy value is only 100 grams. The error is large. Therefore, this traditional weight electronic scale can not be used for other purposes except weighing the body on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its precision value can reach 1 gram even smaller, but its measuring range is generally no more than 10 kilograms, so can n...
