[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.

Embodiment 1
[0017] The present embodiment is a double precision electronic balance, see Figure 1 to Figure 7 As shown, it includes a loading plate 1, a display screen 11, an adjustment switch 12, and four load cell assemblies 2 for weighing the load on the loading plate; the shape of the loading plate in this embodiment is square, and the Made of glass or fiberglass; four load cell assemblies are evenly distributed at the four corners of the bottom wall of the loading plate.
[0018] In this embodiment, each load cell assembly includes a plastic base 3, a first precision load cell 8, a second precision load cell 9, a first supporting foot 5 provided with a first supporting portion 50 and a second The second supporting foot 6 of the supporting part 60 .
[0019] See Figure 5 to Figure 7 As shown, in the present embodiment, the first precision load cell 8 includes a first fixed portion 81, a first elastic bearing portion 82, and a resistance strain gauge (not shown on the figure) arrang...

The present invention discloses a double-precision electronic scale, which comprises a loading plate and weighing sensor assemblies. Each weighing sensor assembly comprises a first precision force sensor, a second precision force sensor, a first support leg with a first support portion and a second support leg with a second support portion. The loading plate is crimped on the first precision force sensor and the second precision force sensor. The first precision force sensor is crimped on the first support leg, and the second precision force sensor is crimped on the second support leg. The second support foot is a resilient support foot. In the free state, the second support portion is lower than the first support portion and the second support portion alone supports the entire electronic scale. When the loading plate carries an object, the loading plate is forced to move the first support portion downwards. When the weight of the carried object exceeds a certain degree, the first support part moves downwards to support the whole electronic scale together with the second support part. The double-precision electronic scale of the invention can be used as a weighing electronic scale and 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 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 gram, but its m...
