Abstract

A nozzle hole mechanism (10) is provided with a nozzle hole (28) which ejects a raw liquid into the atmosphere, a swirl chamber (30) which supplies the raw liquid to the nozzle hole (28), and a path (27) which supplies the raw liquid to the swirl chamber (30), and the swirl chamber (30) and the nozzle hole (28) are located on the same axis. The swirl chamber (30) is configured so that a solid cylindrical front section (30b), which communicates with the nozzle hole, and an annular rear section (30a) are coaxially arranged. The nozzle hole mechanism is configured in such a manner that the raw liquid is supplied to the rear section (30a) and discharged from the nozzle hole (28) via the front section (30b) or, alternatively, in such a manner that the diameter of the nozzle hole (28) is 0.2 mm or less and the length of the nozzle hole (28) is in the range of 0.05-0.3 mm. The configuration enables the nozzle mechanism to spray fine particles over a wide area using a small spray amount.

Description

technical field [0001] The present invention relates to spout mechanisms. Specifically, it relates to a nozzle mechanism attached to an injection member of spray products such as atomization products and pump products. Background technique [0002] For products that pressurize and discharge the content (stock solution) in a container, such as atomization products and pump products, there is known a nozzle mechanism that discharges (sprays) the discharged content in the form of a fine mist. [0003] Patent Document 1 discloses a nozzle mechanism for atomized products including a mechanical break mechanism in which a conical swirling chamber is provided inside the nozzle. The spout mechanism has a spray groove formed in contact with the outer peripheral edge of the swirl chamber, and the content is introduced into the swivel chamber through the spray groove. Therefore, the contents are sprayed out from the nozzle port in a state of swirling in the swirling chamber. Thereby,...
