[0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment switch, 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 measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this kind of traditional weight electronic scale can't be used for other purposes except weighing weight, especially it can't be used as a kitchen electronic scale.
And the existing kitchen electronic scale, its indexing value can reach 1 gram, but its measuring range generally does not exceed 50 kilograms, so can not be used as weighing scale
At present, there are also electronic scales with a division value of 2 grams and a range of 150 kg on the market. They are made of force sensors with high precision and a large range, but they are very expensive and cannot be popularized.

The invention discloses a double-precision dual purpose electronic scale, comprising a carrier plate and weighing sensor assemblies used for weighing loaded objects on the carrier plate. Each weighing sensor assembly comprises a plastic pedestal, a force measurement sensor, a first supporting leg provided with a first supporting portion, and a second supporting leg provided with a second supporting portion, wherein the force measurement sensor comprises a fixing portion, a first precision elasticity force bearing portion and a second precision elasticity force bearing portion. In a free state, the second supporting portion is lower than the first supporting portion, and independently supports a whole electronic scale. When carrying objects, the carrier plate is stressed to drive the first supporting portion to move downwards; when the carried objects exceed a certain weight, the first supporting portion moves downwards and supports the whole electronic scale with the second support portion. The dual purpose electronic scale can be used as a weight electronic scale as well as a kitchen electronic scale.
Description
technical field [0001] The invention belongs to the technical field of structural design of electronic scales, and in particular relates to a double-precision dual-purpose electronic scale. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading board, a display screen, an adjustment switch, 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 measuring range of this kind of weight electronic scale is generally 180 kg, and the division value is 100 g, so the error is large , so this traditional body weight electronic scale can not be used as other things except for weighing body weight on weekdays, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its graduation value can reach 1 gr...
