Quantitative weighing device and coffee machine

Abstract

A quantitative weighing apparatus (10), comprising a charger (100), a swinging assembly (200), a stopper (300), and a photoelectric switch (400). The swinging assembly (200) comprises a swinging rod (210). The swinging rod (210) has a swinging pivot. The charger (100) and the stopper (300) are both provided on the swinging rod (210), and are respectively located at both sides of the swinging pivot. The photoelectric switch (400) and the stopper (300) are provided at the same side of the swinging pivot. Along with the addition of materials to the charger (100), the swinging rod (210) can swing and drive the stopper (300) to move. The photoelectric switch (400) is located on a movement path of the stopper (300). The photoelectric switch (400) is turned off when the stopper (300) moves to a position between an emitter electrode and a receiver electrode of the photoelectric switch (400), so as to form a photoelectric sensing signal and output same. Also provided is a coffee maker comprising the quantitative weighing apparatus. The provided quantitative weighing apparatus is simply structured and convenient to operate, has high cost performance, and can implement precise configuration of materials.

Description

technical field [0001] The invention relates to the technical field of weighing devices, in particular to a quantitative weighing device and a coffee machine. Background technique [0002] With the improvement of people's material living standards, people's life taste is also gradually improved. In order to meet consumers' needs for high quality, precise control and convenient life, many similar weighing machines have been launched on the market, but most of them are Using complex structures such as gravity sensors and liquid crystal displays, this type of machine has high precision in weight control, but the cost of the machine is high, which cannot satisfy consumers' pursuit of low-cost, cost-effective products; some machines use the specified grinding time to control the powder. Weight, the accuracy of this type of machine to control the weight of powder is insufficient, which cannot satisfy consumers' pursuit of high-quality products, convenient operation, and precise we...
