Abstract
A flow channel device includes a first storage part that stores liquid, a first flow channel through which liquid in the first storage part passes, and a second flow channel through which liquid passes to the first storage part, in which a thickness of the first flow channel is smaller than a thickness of the second flow channel.
Claims13
A flow channel device comprising:
- a first storage part that stores liquid;
- a second storage part that stores liquid to be introduced into the first storage part;
- a first flow channel through which the liquid in the first storage part passes;
- a second flow channel which is connected to the second storage part and the first storage part and through which the liquid passes from the second storage part to the first storage part;
- and
- a first gas discharge channel that discharges a gas inside the second storage part out of the second storage part, wherein
- a thickness of the first flow channel is smaller than a thickness of the second flow channel,
- a thickness of the first gas discharge channel is smaller than a thickness of the second flow channel;
- and
- a third flow channel that enables the liquid to pass to the second storage part, wherein
- the second storage part is connected to the second flow channel, and
- an intersection is formed between a first straight line that overlaps a flow direction of the liquid flowing into the second storage part from the third flow channel and a second straight line that overlaps a flow direction of the liquid flowing out of the second storage part to the second flow channel.

- and
- a second gas discharge channel that discharges gas in the fourth flow channel out of the fourth flow channel, wherein
- a thickness of the first flow channel is smaller than a thickness of the second flow channel,
- a thickness of the first gas discharge channel is smaller than a thickness of the second flow channel,
- the thickness of the first flow channel is smaller than a thickness of the fourth flow channel,
- a distance between an inlet of the fourth flow channel and a connecting portion of the fourth flow channel and the second gas discharge channel is longer than a distance between the connecting portion of the fourth flow channel and the second gas discharge channel and a connecting portion between the first storage part and the fourth flow channel.
