SWITCH ASSEMBLY FOR USE IN CLEANING AND CARE APPLIANCE, AND CLEANING AND CARE APPLIANCE
Document Type and Number:
WIPO Patent Application WO/2023/082890
Kind Code:
A1
Abstract:
The present invention provides a switch assembly for use in a cleaning and care appliance, and a cleaning care appliance. The switch assembly comprises: a switch; a switch rocker having a distal end and a proximal end, the switch being disposed below the distal end of the switch rocker, enabling the switch rocker to trigger the switch when operated, the rocker having a small arm, a large arm, and a pivoting part located between the small arm and the large arm, a length of the large arm being greater than that of the small arm, and the large arm comprising the distal end. The switch assembly further comprises a first holding portion used to hold the pivoting part of the switch rocker, and a second holding portion used to hold the proximal end of the switch rocker; the second holding portion holds an end of the small arm distant from the pivoting part, so that when no pressing force acts on the switch rocker, the small arm of the switch rocker is bent and deformed to be in a pretensioned state, while the switch rocker generates a first torque around the pivoting part to enable the large arm to be distant from the switch. The present invention can ensure compactness of layout of components inside a housing, while satisfying ergonomic design requirements for the configuration position of a switch part on a handle housing.
