Description

Electronic weighing device without scale

Technical field

The invention relates to an electronic device, in particular to an electronic weighing device without a scale.

Background technique

At present, as users' health awareness increases, more and more users are using weight scales or body fat scales to monitor their weight or certain human body data. Among them, the body fat scale can not only weigh the user's weight, but also can introduce the current to the user's body and detect the feedback current, thereby determining the user's human body data, ie Bioelectrical Impedance Analysis (BIA) algorithm, for example, the human body The data can include the user's body fat content, human muscle content, body moisture content, etc., users can monitor their physical condition through a variety of data.

Due to the above advantages of body fat scales, more and more users are beginning to use body fat scales. However, in the prior art, both the weight scale and the body fat scale require a scale foot. This is because a general weight scale or a body fat scale uses a small load cell, which generally includes two parts. The first part is an elastic sensitive element for converting the pressure mass of the measured object into the strain of the elastic body. The second part is a resistance strain gauge as a sensing element for synchronizing the strain of the elastomer into a change in resistance value. A typical load cell attaches a resistance strain gauge to an elastic sensing element and forms a bridge in an appropriate manner to convert the mass of the object into an electrical signal. That is to say, if a weighing sensor is used to obtain the weight of the human body, a sensor that can be deformed is required, and a metal gasket is used for cooperation with the sensor. Since the weighing scale or the body fat weighing scale is used, the sensor and the metal gasket are used. Unique in the vertical direction, that is, the weight scale or other components in the body fat scale cannot be stressed in the vertical direction, and once the other components are stressed, the weight data of the weighing will cause a great error.

In order to reduce this error, the technician usually places the metal gasket on the upper surface of the scale foot. This is because the scale script body is vertically standing on the ground, and the general use environment is indoor, the ground is relatively Flat, it can ensure that the sensor and the metal gasket are stressed in the vertical direction, and in order to ensure that the force is unique, the scale foot can not be completely fixed on the chassis, and it needs to be able to be displaced in the vertical direction. That is, the weight scale or the body fat scale in the prior art must have a scale foot, and the scale foot is fixedly fixed on the chassis.

However, when using a prior art weight scale or body fat scale, the user sometimes needs to place the weight scale or body fat scale on a soft carpet, and the soft carpet has a certain elasticity when the body is standing on the scale body. Since the scale foot can be displaced in the vertical direction, the force of the scale foot will be affected in the vertical direction, and the metal gasket placed on the scale foot will also be affected, the weight scale or the body fat scale The weighed weight will have a very large error, which greatly affects the user experience.

It can be seen that the electronic weighing equipment in the prior art has a large error in weighing.
