Improved dual-purpose electronic scale

Abstract

The invention discloses an improved dual-purpose electronic scale comprising a carrying plate, a first precision weighing assembly for supporting the carrying plate, a second precision weighing assembly for supporting the carrying plate and the first precision weighing assembly, and a force guiding element for transmitting a pressure exerted on the element to the second precision weighing assembly. The force guiding element includes a bearing plate with a bearing hole and a pad and support element; the bearing plate is used as a force guiding support part and the bottom of the carrying plate is used as a guiding compressing part. When no object is carried by the carrying plate, the guiding compressing part of the carrying plate is higher than the force guiding support part of the force guiding element; when an object is carried by the carrying plate, the carrying plate presses the elastic support element down under the force and thus moves down; after the force applied on the carrying plate reaches a certain degree, the guiding compressing part compresses the force guiding support part of the force guiding element. According to the invention, the provided electronic scale can be used both as an electronic weighing scale and an electronic kitchen scale; and when the weight of the carried object exceeds a maximum range of the electronic kitchen scale, the electronic kitchen scale can be protected from being damaged effectively.

Description

technical field [0001] The invention belongs to the technical field of electronic balance structure design, and in particular relates to an improved dual-purpose electronic balance. 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 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. The error is relatively large. Large, so this traditional weight electronic scale can not be used for other purposes except for weighing, especially it cannot be used as a kitchen electronic scale. And existing kitchen electronic scale, its graduation value can reach 1 gram, but its measuring range...

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 switch, a power module and a load cell for supporting the loading board. When the weight of the 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. The error is relatively large. Therefore, this traditional weight electronic scale can basically not be used for other purposes except for weighing the weight, especially it cannot 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.
