Abstract

The invention relates to the technical field of weighing equipment. The invention provides a weighing sensing device and an electronic scale. The weighing sensing device is used for converting the bearing capacity of a scale pan of the electronic scale into an electric signal. The device comprises a first sensor and a component force mechanism arranged between the first sensor and the scale pan. The component force mechanism is connected to the scale pan; the first sensor comprises a first fixing part and a first deformation part connected to the first fixing part. The component force mechanism is provided with an abutting end used for abutting against the first deformation part. According to the weighing sensing device, the component force mechanism and the first sensor bear the weight ofa heavy object together; therefore, the first deformation part is prevented from being continuously pressed and deformed to exceed the maximum range of the first deformation part, so that unrecoverable deformation of the first deformation part is avoided; the first sensor is effectively prevented from being damaged due to overload work, overload work of the first sensor is prevented in this way,the thickness of the first deformation part of the first sensor does not need to be increased, and the detection accuracy of the first sensor is effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of weighing equipment, and in particular provides a weighing sensor device and an electronic scale. Background technique [0002] Electronic scale is a kind of weighing instrument commonly used in daily life. With the rise of weight loss trend, electronic scale has basically become a necessary daily appliance in the family. [0003] Electronic scales generally include a weighing pan and a load cell arranged at the bottom of the weighing pan. When a heavy object is placed on the weighing pan, the weight of the heavy object is transferred to the weighing sensor through the weighing pan, causing the shrapnel of the weighing sensor to deform under pressure. , the load cell converts the load-bearing capacity of the weighing pan into an electrical signal, so that the weight value of the heavy object is displayed on the display screen. [0004] However, after the traditional load cell is overloaded, the shrapnel o...
