Abstract
There is provided a micro pump, including: a channel forming substrate having an inlet and an outlet; an upper substrate connected to the channel forming substrate and having a first hole connected to the inlet and a second hole connected to the outlet; and an adhesive member disposed between the channel forming substrate and the upper substrate to bond the channel forming substrate and the upper substrate and having a first valve opening and closing the inlet and a second valve opening and closing the outlet.
Claims18
A micro pump, comprising:
- a channel forming substrate having an inlet and an outlet;
- an upper substrate connected to the channel forming substrate and having a first hole connected to the inlet and a second hole connected to the outlet;
- and
- an adhesive member disposed between the channel forming substrate and the upper substrate to bond the channel forming substrate and the upper substrate and having a first valve opening and closing the inlet and a second valve opening/closing the outlet,
- wherein the adhesive member includes:
- a first cut line defining first areas of the first valve and the second valve;
- and
- a second cut line defining second areas of the first valve and the second valve,
- wherein the first cut line has a curved shape having a first radius, and the second cut line has a curved shape having a second radius,
- wherein the first radius is greater than the second radius,
- wherein the inlet is formed by a semicircle having a third radius larger than the first radius and a semicircle having a fourth radius smaller than the second radius, and
- the first hole is formed by a semicircle having a fifth radius smaller than the first radius and a semicircle having a sixth radius larger than the second radius.
