Intelligent dual-order and dual precision weighing electronic scale

Abstract

The present invention discloses an intelligent dual-order and dual precision weighing electronic scale. The scale comprises an object carrying plate configured to dispose an object to be weighed, a pedestal arranged at the lower portion of the object carrying plate and dual-order and dual-precision weighing sensors arranged in the pedestal and configured to support the object carrying plate. Each sensor comprises a first soleplate, a first precision weighting sensor, an elastic supporting piece, a second precision weighting sensor and a support leg. The soleplate is provided with an installation plate part and a guiding force support part configured to transmit the pressure to the installation plate part; the elastic supporting piece, the first precision weighting sensor, the installation plate part, the second precision weighting sensor and the support leg are crimped in order; and the top of the elastic supporting piece is higher than the top of the guiding force support part in the free state, and the top of the elastic supporting piece is moved downwards when being pressed. The intelligent dual-precision weighting sensor has dual-order continuous range and has different precision values in each-order range.

Description

Technical field [0001] The invention belongs to the technical field of weighing instruments, and specifically relates to an intelligent double-stage double-precision weighing electronic scale. Background technique [0002] The weight electronic scales currently on the market mainly include a load board, a display screen, an adjustment button, a power module, and a load cell for supporting the load board. Its function is mainly used for weighing the human body, and is generally used for weighing the human body. After the weight of the load exceeds the preset value, the display 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, which has a large error. Therefore, this traditional electronic weight scale cannot be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale. The existing el...

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.
