Problems solved by technology

[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.

Abstract

The invention discloses an intelligent dual-step double-precision weighing sensor comprising a mounting seat, a first precision weighing sensor, a second precision weighing sensor, a supporting leg and an elastic supporting element. The mounting seat is provided with a mounting plate part and a guiding and supporting part for transmitting pressures to the mounting plate part; and the elastic supporting element, the first precision weighing sensor, the mounting plate part, the second precision weighing sensor, and the supporting leg are arranged successively in a pressing mode. The top of the elastic supporting element is higher than the top of the guiding and supporting part in a free state and moves down when forces are applied on the top of the elastic supporting element. The intelligent dual-step double-precision weighing sensor has the dual-step continuous ranges and has different precision values in ranges at all steps.

Description

technical field [0001] The invention belongs to the technical field of weighing sensor structure design, and in particular relates to an intelligent double-stage double-precision weighing sensor. 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 gra...
