Abstract
An atomizer includes a first piezoelectric pump, a second piezoelectric pump, a first flow path connected to the first piezoelectric pump, a second flow path connected to the second piezoelectric pump and merged with the first flow path, a third flow path connected to a merging portion of the first flow path and the second flow path, the third flow path having a first end and a second end, a liquid storage portion, and a nozzle including a gas supply flow path connected to the second end of the third flow path, a liquid supply flow path connected to the liquid storage portion, and a blow-out port, wherein the third flow path has a bent portion between the first end and the second end.
Claims20
An atomizer comprising:
- a first piezoelectric pump configured to blow out gas from a first discharge port;
- a second piezoelectric pump configured to blow out gas from a second discharge port;
- a first flow path connected to the first discharge port of the first piezoelectric pump;
- a second flow path connected to the second discharge port of the second piezoelectric pump and merged with the first flow path;
- a third flow path connected to a merging portion of the first flow path and the second flow path, the third flow path having a first end and a second end;
- a liquid storage portion configured to store liquid;
- a nozzle including a gas supply flow path connected to the second end of the third flow path, a liquid supply flow path connected to the liquid storage portion, and a blow-out port, the blow-out port connected to the gas supply flow path and the liquid supply flow path in such a manner that gas supplied to the gas supply flow path and liquid supplied to the liquid supply flow path are merged to supply the merged gas and liquid to the blow-out port, wherein
- the third flow path has a bent portion between the first end and the second end.
An atomizer comprising:
- a first piezoelectric pump configured to blow out gas from a first discharge port;
- a second piezoelectric pump configured to blow out gas from a second discharge port;
- a first flow path connected to the first discharge port of the first piezoelectric pump;
- a second flow path connected to the second discharge port of the second piezoelectric pump and merged with the first flow path;
- a third flow path connected to a merging portion of the first flow path and the second flow path, the third flow path having a first end and a second end;
- a liquid storage portion configured to store liquid;
- a nozzle including a gas supply flow path connected to the second end of the third flow path, a liquid supply flow path connected to the liquid storage portion, and a blow-out port, the blow-out port connected to the gas supply flow path and the liquid supply flow path in such a manner that gas supplied to the gas supply flow path and liquid supplied to the liquid supply flow path are merged to supply the merged gas and liquid to the blow-out port;
- and
- a fourth flow path provided between the liquid storage portion and the liquid supply flow path, wherein
- the third flow path includes a first portion including the first end, a third portion including the second end, and a second portion provided between the first portion and the third portion, the second portion positioned below the first portion and the third portion, the second portion including a bent portion, and
- an opening direction of an opening portion on a side of the liquid supply flow path in the fourth flow path intersects with an extending direction from the gas supply flow path to the blow-out port.
