Abstract

The invention discloses a micro water pump capable of accurately controlling flow. The micro water pump comprises an upper cover, a valve seat, a water bag seat, a base casing, water bags, a bent lever, a drive shaft, an eccentric wheel, a motor, an optoelectronic switch and an output circuit board, wherein a water outlet and a water inlet are formed in the upper cover; water inlet holes and water outlet holes are formed in the valve seat; the water bags for sucking water into the water inlet holes or pushing water out of the water outlet holes are mounted on the water bag seat; the water bags are driven by the bent lever, the drive shaft and the eccentric wheel to work; the motor and the optoelectronic switch are mounted on the base casing; photoelectric shading pieces are mounted on the eccentric wheel or a motor shaft; the optoelectronic switch is electrically connected with the output circuit board; the output circuit board is used for being electrically connected with an external motor controller. Based on output revolution information, a user can accurately control the revolution of the motor through combination of the revolution information and the external motor controller, so that different quantities of stable water flow under different back pressure is obtained, and the micro water pump has the characteristics that the flow control is accurate, the work is stable and smooth and the service life is long.

Description

technical field [0001] The invention relates to a micro water pump, in particular to a micro water pump whose flow rate can be precisely controlled. Background technique [0002] Diaphragm-type micro-pumps are provided with circular motion by the motor, and then the diaphragm inside the pump (there are many types of diaphragms) is reciprocated by a mechanical device, thereby compressing and stretching the air in the pump chamber, and acting on the one-way valve. Under the pressure, a pressure difference is generated between the water outlet or water inlet and the external atmospheric pressure. Under the action of the pressure difference, the water is pressed into the water inlet and then discharged from the water outlet. This kind of micro water pump has been well applied in occasions such as small household appliances, medical equipment, etc. However, it is difficult for the existing micro water pump to achieve accurate regulation of the flow rate. [0003] In view of this...
