Patent ID: 8215929

Claim:
A detachable pump, comprising: a top module, including: a motor set, electrically connected to an external power supply for providing motive force; and at least a top elastic member, capable of being driven to move in reciprocation by the motor set; and a bottom module, arranged beneath the top module in a manner that it is connected to the top module by a detachable connection mechanism, comprised of: a base, configured with a channel for enabling fluid to flow in and out of the base therefrom; at least a single one-way valve, installed in the channel for preventing fluid flow in a direction toward the base; a diaphragm element, being received inside the base; and at least a bottom elastic member, capable of elastically countering the resilience of the top elastic member caused by the reciprocating movement of the top elastic member and thus propelling the diaphragm element to move accordingly to create suction; wherein the detachable connection mechanism comprises: a moveable part, arranged on the top module, having a moving threaded section, being free to move in relation to the top module; and a fixed part arranged on the bottom module, immovably fixed to the bottom module, having a threaded section capable of being screwed into the moving threaded section of the movable part; wherein the diaphragm is located within a circumferential boundary of the threaded section on the fixed part; wherein the detachable pump provides a negative pressure causing fluid to be drawn into and exhausted by the detachable pump.
