Problems solved by technology

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.
In addition, if you choose a weighing sensor with high precision to achieve both weighing and use as a kitchen electronic scale, there is no problem technically, but considering that the accuracy must be at least in grams or 0.1g, it is still a problem. To reach the upper limit of the measuring range of 180 kg, the cost of this load cell will be relatively high, at least in terms of price, it cannot compete with traditional electronic scales

Embodiment 1

[0019] This embodiment is a dual-purpose electronic scale with a single board, see Figure 1 to Figure 6 As shown, it includes a loading board 1, a display screen 11, an adjustment switch 12, a power supply assembly 13, four first load cell modules 3 with first support feet 2, four second scales with second support feet 4 The heavy sensor module 5, and the four elastic supports 6 whose height changes under the action of external force.

[0020] In this embodiment, the first load cell module 3 and the second load cell module 5 are directly fixed on the bottom wall of the loading plate, and the bottom end of the second support leg is higher than the bottom end of the first support leg.

[0021] In order to allow the first supporting foot to perform the applied weighing function, in this embodiment, the elastic supporting member is supported under the second supporting foot.

[0022] In this embodiment, the specific structure of the first load cell module is as follows: it inclu...

Embodiment 2

[0031] This embodiment is basically the same as Embodiment 1, the difference is: see Figure 7 to Figure 10 As shown, this embodiment includes four first load cell modules and one second load cell module, and the number of elastic supports is only one, that is, the four second support feet in Embodiment 1 are changed to only one A second supporting foot structure.

[0032] The specific structure of the elastic supporting member in this embodiment is as follows: it includes an upper positioning member 61 integrally arranged with the support column 85, a lower positioning member 62 arranged directly below the upper positioning member, a return support spring 63, a limit screw 64, The supporting plate 68 arranged at the bottom of the lower positioning member; the upper positioning member is located at the bottom of the support column 85, and the center of the bottom wall is provided with a screw hole 611 and an upper annular limit groove 612 around the screw hole, and the center ...

Abstract

The invention discloses a single-plate dual-purpose electronic scale. The single-plate dual-purpose electronic scale comprises a loading plate, a first weighing sensor module with a first support foot, a second weighing sensor module with a second support foot, and an elastic support member. The second weighing sensor module comprises an insulation casing body, a mounting groove, a second force measuring sensor, an elastic cover and a support column. The elastic support member comprises an upper positioning member, a lower positioning member, a resetting support spring, a limit screw and an elastic pad. The upper positioning member is located on the bottom end of the support column. When the weight of an object to be weighed is less than or equal to the maximum nominal weight value of the second weighing sensor module, the bottom end of the elastic support member is lower than the bottom end of the first support foot. When the weight of the object to be weighed is greater than the maximum nominal weight value of the second weighing sensor module, the bottom end of the elastic support member and the bottom end of the first support foot are located in the same plane. The single-plate dual-purpose electronic scale provided by the invention can be used as a weight electronic scale with large scale and low precision, and can be used as a kitchen electronic scale with small scale and high precision.

Description

technical field [0001] The invention belongs to the technical field of electronic scale structure design, and in particular relates to a single-board dual-purpose electronic scale. Background technique [0002] The weight electronic scales currently on the market are mainly composed of a loading tray, a display screen, a power module and a load cell. The display screen starts to display the value, and the default value is generally 5 kg; in addition, the range of this type of electronic scale is generally 180 kg, which is relatively large. In order to reduce costs, this type of electronic scale generally uses weighing with lower precision For the sensor, for example, for the unit of kilogram, its display value is one decimal place, that is, its accuracy is 100 grams. 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. In addition, if you choo...
