A device for supplying a mist of liquid, the device is intended to be used in combination with a container with an opening for containing the liquid, the device comprising: a main body, the main body comprising: a center axis; a liquid chamber formed inside the main body, into which a predetermined amount of liquid can be taken up; a first port formed in a base wall of the main body forming a bottom surface of the liquid chamber so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; a second port formed in the base wall of the main body at a position different from the position where the first port is formed so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; an aperture connected to the liquid chamber, through which a mist of liquid can be released to the outside of the main body; a connecting section provided on the main body so as to extend from the main body in a direction away from the base wall of the main body and used for connecting the container to the main body; an atomizing element interposed between the liquid chamber and the aperture to atomize the liquid taken up in the liquid chamber and release a mist of the liquid to the outside of the main body from the aperture; a first valve mounted on the main body corresponding to the first port, wherein the first valve permits the liquid in the container flowing into the liquid chamber through the first port under the influence of gravity, and prevents the liquid in the liquid chamber flowing into the container under the influence of gravity; and a second valve mounted on the main body corresponding to the second port, wherein the second valve prevents the liquid in the container flowing into the liquid chamber through the second port under the influence of gravity, and selectively permits or prevents the liquid in the liquid chamber flowing into the container through the second port under the influence of gravity. a main body, the main body comprising: a center axis; a liquid chamber formed inside the main body, into which a predetermined amount of liquid can be taken up; a first port formed in a base wall of the main body forming a bottom surface of the liquid chamber so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; a second port formed in the base wall of the main body at a position different from the position where the first port is formed so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; an aperture connected to the liquid chamber, through which a mist of liquid can be released to the outside of the main body; a center axis; a liquid chamber formed inside the main body, into which a predetermined amount of liquid can be taken up; a first port formed in a base wall of the main body forming a bottom surface of the liquid chamber so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; a second port formed in the base wall of the main body at a position different from the position where the first port is formed so as to face the opening of the container when the device and the container are combined with each other, through which the liquid can flow; an aperture connected to the liquid chamber, through which a mist of liquid can be released to the outside of the main body; a connecting section provided on the main body so as to extend from the main body in a direction away from the base wall of the main body and used for connecting the container to the main body; an atomizing element interposed between the liquid chamber and the aperture to atomize the liquid taken up in the liquid chamber and release a mist of the liquid to the outside of the main body from the aperture; a first valve mounted on the main body corresponding to the first port, wherein the first valve permits the liquid in the container flowing into the liquid chamber through the first port under the influence of gravity, and prevents the liquid in the liquid chamber flowing into the container under the influence of gravity; and a second valve mounted on the main body corresponding to the second port, wherein the second valve prevents the liquid in the container flowing into the liquid chamber through the second port under the influence of gravity, and selectively permits or prevents the liquid in the liquid chamber flowing into the container through the second port under the influence of gravity.
