## Abstract

A cleaning device connects to a mobile device through an interface. The cleaning device includes a trigger mechanism which includes at least one plate body, two elastic members connect to the plate body, and a baffle mechanism resting on the plate body. The baffle mechanism comprises at least one baffle, a torsion spring, and a processing unit. The baffle defines a first elastic sheet and the plate body defines a second elastic sheet. When a pressure is applied on the mobile device, the plate body is driven to rotate the baffle to make the first elastic sheet on the baffle contact the second elastic sheet on the plate body. The processing unit produces a trigger signal to execute a function of function modules when the first elastic sheet contacts the second elastic sheet.
