Document Type and Number:
WIPO Patent Application WO/2023/274188
Kind Code:
A1
Abstract:
The present invention provides a cleaning and nursing appliance, and a transducer device and a pressure alarm mechanism therefor. The transducer device according to the present invention comprises a transducer, wherein an elastic assembly comprises at least one proximal elastic member and at least one distal elastic member; the proximal elastic member and the distal elastic member are respectively provided with a first edge and a second edge; the first edge is fixedly connected to a driving shaft so as to move along with the driving shaft, and the second edge forms a fixed edge when the proximal elastic member and the distal elastic member are elastically deformed; the plane of the proximal elastic member forms a first angle with respect to a median plane of a rack, and the plane of the distal elastic member forms a second angle with respect to the median plane. By using the transducer device according to the present invention, the elastic members can be protected from failure, the size of the transducer device can be decreased, and the achievement of the pressure alarm mechanism by means of the elastic assembly can be facilitated.
