CROSS REFERENCE TO RELATED APPLICATIONS

This application is a Continuation In Part of applicant's earlier application Ser. No. 15/621,020, filed Jun. 13, 2017.

FIELD OF THE INVENTION

The present invention relates to a meter-type magnetic pump and a measuring module thereof, and more particularly, to a meter-type magnetic pump for flow measurement and a light interrupting module thereof.

BACKGROUND OF THE INVENTION

During operation of a traditional micro-pump, in order to control the flow of water in and out of the pump, an external flowmeter is typically connected to control the flow. However, using an external flowmeter to control the flow, the working flow of the micro-pump and flowmeter have to be calculated, so that the two can be matched in the operation process. If the two cannot match in operation, it will lead to inability to control flow or control instability. Moreover, the use of micro-pump with an external flowmeter, in addition to having to calculate the working flow of the two, has shortcomings such as larger number of components and increased cost increases.
In addition, in order to improve the conventional micro-pumps, some manufacturers have designed the flowmeter inside the structure of the micro-pump. This results in the increase of the internal components and a more complicated micro-pump structure, increasing the number of components and the cost of the micro-pump instead of reducing them.
Furthermore, in order to improve the conventional micro-pumps, the micro-pump is designed to be of a diaphragm-type, in which circular motion is provided by a motor, and then the diaphragm inside the micro-pump performs reciprocating movements through a mechanical device, which results in compression of air inside the micro-pump cavity. Through a one-way valve, a pressure difference is produced between the outlet or the inlet of the micro-pump and the atmospheric pressure outside. Due to this pressure difference, water is compressed into the inlet, and then discharged from the outlet, so that such micro-pumps are particularly suitable in products such as small appliances and medical equipment, but it is still difficult to accurately control the flow.
Therefore, there is a need in the industry for a solution that addresses the shortcomings associated with flow control of conventional micro-pumps.
