Abstract
A liquid spray device prevents diffusion of a poisonous gas and odor in a sprayed liquid. A base includes an ejection orifice for ejecting acidic water, first and second feed paths communicating with ejection and spray orifices to feed acidic and alkaline water, respectively. The second feed path is open so that its front end continuously makes a circuit on the side surface of the base. A rotary part is disposed to rotate along the side surface of the base. The rotary part includes the spray orifices disposed to surround the periphery of the ejection orifice. The rotary part includes communication paths communicating with the respective spray orifices and the second feed path. The respective spray orifices spray alkaline water while rotating around the periphery of the ejection orifice to surround the periphery of acidic water ejected from the ejection orifice with the alkaline water in a curtain-like manner.
