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.

Embodiment 1

[0020] This embodiment is an adjustable double-stage double-precision weighing electronic scale, see Figure 1 to Figure 6 As shown, it includes a loading plate 91 for placing objects to be weighed, a base 92 arranged below the loading plate and four double-stage double-precision load cells 93 for supporting the loading plate arranged in the base; There are four through holes 94 in the base, and each double-stage double-precision weighing sensor is fixed in a corresponding through hole by bonding.

[0021] Each double-stage double-precision load cell includes a mount 1, a first-precision load cell 2, a second-precision load cell 3, a supporting foot 4, an elastic support 5 and an adjustment mechanism 6 for adjusting the height of the elastic support.

[0022] The mounting seat is provided with a mounting plate portion 11 and a force guiding support portion 12 for transmitting the pressure received by itself to the mounting plate portion; an elastic support member, a first prec...

Embodiment 2

[0045] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 7 and Figure 8 As shown, a static contact 123 is set at the top of the force guiding support part, and a moving contact 514 adapted to the static contact is set on the force guiding crimping part of the upper support; when the force guiding crimping part is crimped on the force guiding When it is on the supporting part, the moving contact is crimped and arranged on the static contact, and the two realize electrical connection. In practice, when the moving contact and the static contact are in electrical contact, an electrical signal is generated to the connected external central control circuit. When the central control circuit receives the signal, the second precision load cell measurement is displayed on the display When the central control circuit does not receive the signal, the data measured by the first precision load cell will be displayed on the display screen; that is to say...

Abstract

The invention discloses a dual-step dual-precision electronic weighing scale with the adjusting function. The electronic weighing scale comprises a carrying plate for placing to-be-weighed object, a pedestal arranged below the carrying plate, and dual-step dual-precision weighing sensors that are arranged in the pedestal and are used for supporting the carrying plate. All dual-step dual-precision weighing sensors consist of mounting seats, first precision weighing sensors, second precision weighing sensors, supporting legs, elastic supporting members and adjusting mechanisms for adjusting the heights of the elastic supporting members. The mounting seats are provided with a mounting plate parts and guiding and supporting parts for transmitting applied pressures to the mounting plate parts; the elastic supporting members, the first precision weighing sensors, the mounting plate parts, the second precision weighing sensors, and the supporting legs are arranged successively in a pressing mdoe. The tops of the elastic supporting members are higher than the tops of the guiding and supporting parts in a free state and move down when forces are applied on the tops of the elastic supporting members. The dual-step dual-precision electronic weighing scale 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 adjustable double-stage double-precision weighing 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 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 re...
