Abstract

A hair care device includes a sprayer disposed inside the housing. The sprayer includes a tank that stores therein liquid, two-fluid nozzle that discharges atomized liquid, a liquid feed pump that feeds liquid from the tank into two-fluid nozzle, and an air pump that is connected to two-fluid nozzle. Two-fluid nozzle includes first orifice unit for mixing the liquid from liquid supply channel with the air from air supply channel to atomize the liquid, and mist release port for discharging the liquid atomized in first orifice unit. Second orifice unit having an inner diameter larger than the inner diameter of first orifice unit is provided between first orifice unit and mist release port.

First claim

1 . A beauty equipment comprising:
a housing including an intake port and a discharge port; and a sprayer that is disposed inside the housing, wherein the sprayer includes: a reservoir that stores therein liquid; a two-fluid nozzle that discharges atomized liquid generated by atomizing the liquid; a liquid feed pump that feeds the liquid from the reservoir into the two-fluid nozzle; and an air pump that is connected to the two-fluid nozzle, the two-fluid nozzle includes: a liquid supply channel to which the liquid from the liquid feed pump is supplied; an air supply channel to which air from the air pump is supplied; a first orifice unit for mixing the liquid from the liquid supply channel with the air from the air supply channel to atomize the liquid; and a mist release port for discharging the liquid atomized in the first orifice unit, and the two-fluid nozzle further includes a second orifice unit provided between the first orifice unit and the mist release port, the second orifice unit having an inner diameter larger than an inner diameter of the first orifice unit.

2 . The beauty equipment according to claim 1 , wherein the second orifice unit has an increasing diameter portion having an inner diameter increasing in a direction from the first orifice unit to the mist release port.

3 . The beauty equipment according to claim 1 , wherein the second orifice unit has a constant diameter portion having an inner diameter that is constant.

4 . The beauty equipment according to claim 1 , wherein the two-fluid nozzle includes:
a body including the first orifice unit; and a counterpart including the second orifice unit.

5 . The beauty equipment according to claim 4 , wherein the counterpart is formed of a material having a higher thermal expansion coefficient than a thermal expansion coefficient of a material of which the body is made.
