Replaceable device and detection method thereof

Abstract

The present disclosure provides a replaceable device and a detection method thereof. The replaceable device includes a main body and a replacement piece. The main body includes a detection circuit, and the detection circuit stores a usage count. The replacement piece is detachably connected to the main body, the replacement piece includes an identification circuit, and the identification circuit is electrically connected to the detection circuit. Wherein, when the detection circuit determines that the identification circuit is in a first state, the detection circuit resets the usage count and starts to count; when the detection circuit determines that the identification circuit is in a second state, the detection circuit continues the usage count and continues to count. Therefore, the present disclosure provides a replaceable device with high convenience, high safety, and high sanitary conditions.
