WIPO Patent Application WO/2023/006053
Kind Code:
A1
Abstract:
The present invention provides an integrated high-precision weighing module, comprising a scale pan (10), a lever (20), an internal calibration system (30), a bottom plate assembly (40),and a sensor main body (50). The scale pan (10) is mounted on the lever (20), and the lever (20) is connected to the sensor main body (50); wherein the internal calibration system (30), the sensor main body (50), and the lever (20) are arranged transversely, and the internal calibration system (30) and the sensor main body (50) are respectively attached to the bottom plate assembly (40). The weighing module of the present invention has less number of parts, smaller in size, and is easy to manufacture, and the internal calibration system and a weighing unit can be implemented with one lever. The weighing module has a great cost advantage over existing products and has additional features such as the internal calibration system, being highly dustproof and waterproof, easy to clean, and the weighing module can ensure long-term reliability of a product and is easy for customers to operate.
