Abstract
A particle measuring device includes a flow cell unit including a cell hollow portion in which a liquid sample flows, a mount unit including an accommodation hole accommodating at least a portion of the flow cell unit, and a resonance unit positioned behind the mount unit and coupled to the mount unit. The mount unit includes a mount body in which the accommodation hole is formed, and a passage hole depressed in an outer surface of the mount body and communicating with the accommodation hole. The resonance unit includes a resonance body behind the mount body and coupled to the mount body, and a cavity that is a space formed in the resonance body and communicates with the passage hole.

A particle measuring device comprising:
- a flow cell unit including a cell hollow portion in which a liquid sample flows;
- a mount unit including an accommodation hole accommodating at least a portion of the flow cell unit;
- and
- a resonance unit positioned behind the mount unit and coupled to the mount unit,
- wherein the mount unit includes:
- a mount body in which the accommodation hole is formed;
- and
- a passage hole depressed in an outer surface of the mount body and communicating with the accommodation hole,
- wherein the resonance unit includes:
- a resonance body behind the mount body and coupled to the mount body;
- a cavity for acoustic resonance that is an empty space without accommodating any other element and formed in the resonance body, the cavity communicating with the passage hole;
- and
- a measurement hole depressed in a rear surface of the resonance body and communicating with the cavity, wherein with reference to a cross section perpendicular to a front-rear direction, a size of a cross section of the measurement hole is less than a size of a cross section of the cavity.
