Switch detection assembly and faucet having the same

A switch detection assembly used to perform switch detection on a movement stroke of a linear continuous shape object, including a sleeve sliding pair, the sleeve sliding pair has a movement stroke having a first direction and a second direction that deviate from each other, the sleeve sliding pair is used for the linear continuous shape object to extend and receives a unidirectional force of the linear continuous shape object to generate the movement stroke in the first direction, the movement stroke in the second direction of the sleeve sliding pair is capable of continuously reset, and the movement stroke is accepted and a switch signal output is generated;

• the switch detection assembly further comprises a fixing bracket, a sliding sleeve, an elastic reset element, a diameter expanding element and a proximity sensor,
• the fixing bracket is fixedly provided and includes a fixing sleeve, the fixing sleeve has a passage for the linear continuous shape object to pass through, and defines two ends of the passage as a first end and a second end corresponding to the first direction and the second direction;
• the sliding sleeve is movably mounted over the fixing sleeve, so as to be able to make a linear reciprocating movement towards the first end or the second end relative to the fixing sleeve and have a movement stroke;
• the fixing bracket and the sliding sleeve form the sleeve sliding pair;
• the elastic reset element is used to achieve the reset and includes a first force application action end and a second force application action end, the first force application action end and the second force application action end respectively act on the fixing sleeve and the sliding sleeve, so that the elastic reset element generates an elastic restoring force against the movement of the sliding sleeve towards the first end, and the elastic restoring force is in a direction towards the second end of the passage;
• the diameter expanding element is used to achieve the unidirectional force application, and the diameter expanding element is fixedly installed in at least one position of the linear continuous shape object, so that when the linear continuous shape object moves towards the first end in the passage of the fixing sleeve, the diameter expanding element applies pressure to the sliding sleeve and generates the movement stroke relative to the fixing sleeve;
• the proximity sensor is used to accept the movement stroke and generate the switch signal output, the proximity sensor is installed in a range roughly equivalent to the movement stroke of the sliding sleeve, so that when the sliding sleeve makes the linear reciprocating movement, the proximity sensor can accept stroke change of the sliding sleeve and generate the switch signal output.
