Description

Technical Field

[0001] The utility model relates to the technical field of switches, in particular to a toilet seat switch and a toilet seat ring. Background Art

[0002] Currently, most smart toilets in the industry implement human seat sensing through capacitive sensing. Capacitive sensing uses the human body as a conductive medium to change the capacitance of a capacitor. Most capacitive sensing methods utilize single-point sensing. When the human body is located far from the sensing area or when there is insulating material on the seat, the sensing signal cannot be triggered. Therefore, smart toilets in the industry must expand the sensing area to include the human body in the sensing area in order to trigger the seat sensing signal, which increases cost and manufacturing difficulty. Utility Model Content
