Title:
ELECTRIC TOOTHBRUSH WITH BRUSH HEAD PRESSURE SENSOR
Document Type and Number:
WIPO Patent Application WO/2019/119625
Kind Code:
A1
Abstract:
An electric toothbrush is disclosed. The electric toothbrush comprises: a handle; a driving component located inside the handle; an output shaft of the driving component, extending from the handle to the outside of the same; a brush head located at an end of the output shaft away from the handle and connected to the output shaft; and a force trigger component and a force detection component opposingly provided on a surface of the output shaft. The force trigger component is used to generate a focused force at a position of the force trigger component when the output shaft moves. The force detection component is used to detect the force at the position of the force trigger component to obtain a pressure corresponding to the force. The force trigger component can create a focused force phenomenon. The force detection component can detect the force at the position of the force trigger component and obtain a pressure value according to the force. The electric toothbrush of the present invention has a simple structure for detecting pressure, thereby lowering manufacturing cost and increasing economic benefit of electric toothbrushes.
