Title:
GRINDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/228201
Kind Code:
A1
Abstract:
A grinding device, which can automatically output a ground powder (such as coffee powder) of a certain weight and degree of coarseness every time. In the grinding device, a driving electric motor (300) is electrically connected to a control unit. An output shaft of the driving electric motor (300) is dynamically connected to lower grinding blades (100). Upper grinding blades (400) are cooperatively mounted with the lower grinding blades (100). An output shaft of an adjusting electric motor (700) is cooperatively mounted with an adjusting structure (500), and the adjusting electric motor (700) is electrically connected to the control unit. The adjusting structure (500) is rotatably mounted on a body frame (200), is sleeved outside the upper grinding blades (400), and is used to limit the rotation of the upper grinding blades (400) and adjust a cooperative gap between the upper grinding blades (400) and the lower grinding blades (100). An angle sensor (600) is used to send a sensed rotation angle to the control unit by means of a signal. The control unit is used to control the rotation of the adjusting electric motor (700) and drive the adjusting structure (500) to achieve a set target rotation angle. The target duration corresponding to the target rotation angle is determined according to a preset correspondence between the rotation angle and a duration, thereby controlling the duration in which the grinding blades (100) are driven by the driving electric motor (300).
