Nebulizer systems having a small size that can be mounted on a sales stall to humidify and freshen fresh products displayed for sale, or in a vehicle to humidify and freshen the air and make it pleasant to breathe.

A liquid dispensing method including steps of: providing a dispensing device having a refill time (RT) and repeatedly energizing the activation elements at a frequency greater than about 1/(RT). The device includes: a plurality of liquid dispensing elements, each element including: a chamber having a height (H), a nozzle having a diameter (D), an activation element having a length (L), and the refill time (RT); a liquid containing reservoir in fluid communication with the liquid dispensing elements; and a control element in electrical communication with the liquid dispensing elements. The ratio of the nozzle diameter (D) to chamber height (H) is between about 3 and about 10.

A drug solution tank of the present invention is a drug solution tank for an ultrasonic inhaler, including a drug solution reservoir portion having an upper edge that surrounds an opening and a bottom portion formed so as to protrude downward, a flange portion formed so as to extend outward from the upper edge of the drug solution reservoir portion, and a leg portion that is continuous with the outer perimeter or lower surface of the flange portion, is formed so as to surround the drug solution reservoir portion, and extends downward past the bottom portion of the drug solution reservoir portion.

Provided is a piezoelectric material that is free of lead and potassium, has satisfactory insulation property and piezoelectricity, and has a high Curie temperature. The piezoelectric material includes a perovskite-type metal oxide represented by the following general formula (1): General formula (1) (Na.sub.xM.sub.1-y)(Zr.sub.z(Nb.sub.1-wTa.sub.w).sub.y(Ti.sub.1-vSn.sub.v).sub.(1-y-z))O.sub.3 where M represents at least any one of Ba, Sr, and Ca, and relationships of 0.80≦x≦0.95, 0.85≦y≦0.95, 0<z≦0.03, 0≦v<0.2, 0≦w<0.2, and 0.05≦1−y−z≦0.15 are satisfied.

A container structure for a floating type humidifier according to the present disclosure, in which the floating type humidifier is installed to be movable in a state in which the floating type humidifier floats on water stored in an accommodating space, includes: a lower body which has therein the accommodating space opened at an upper side thereof, and has a lower surface that is horizontally formed and seated on an installation surface; and an upper body which has a lower end that is correspondingly coupled to an upper end of the lower body, and an upper end that is formed to be bent toward the accommodating space so as to have a curved surface, and allows water flowing in a lateral direction by external force to flow back into the accommodating space.

Methods and devices for atomizing a fragrant liquid are disclosed. A reservoir receives a volume of a base liquid. One or more drops of a substance are added to the base liquid to form a volume of an aromatic liquid. A vaporizer atomizes the aromatic liquid, forming a mist that is emitted from the device. The device allows a user to customize the blend of substances that are used to form the aromatic liquid.

Some embodiments of the present disclosure provide a water retaining structure and a humidifier with the water retaining structure. The water retaining structure is disposed on a bottom surface of a water tank assembly. The water retaining structure and the water tank assembly are split. The water retaining structure includes a mist collecting portion and a water retaining portion. The mist collecting portion is formed into a mist collecting space. The mist collecting space communicates with a mist outlet tube in the water tank assembly. The water retaining portion is configured to collect water flowing down from the mist outlet tube. The water retaining structure and the water tank assembly are split so that the bottom surface of the water tank assembly is configured as a flat surface, or a height of a structure disposed on the bottom surface is reduced.

An aerosol generator (1) with an active liquid container (4) and a nebulization chamber (2) associated therewith, which is connected to an inlet channel (10) for the supply of carrier gas and to an outlet channel (12) for the discharge of carrier gas mixed with aerosol obtained from the active liquid, is intended to enable a particularly good adjustability of the droplet size of the aerosols contained in the discharged carrier gas and thus a use particularly in the context of a transnasal inhalation therapy. For this purpose, the nebulization chamber (2) has a substantially rotationally symmetrical boundary wall (8), the inlet channel (10) being positioned and oriented in the region of its point of entry into the nebulization chamber (2) in such a way that its longitudinal axis is offset relative to the axis of symmetry of the nebulization chamber (2) in the region of the point of entry and does not intersect the axis of symmetry.

In an ultrasonic atomization apparatus of the present invention, a separator cup and four ultrasonic vibrators are provided to satisfy a reflected wave avoidance condition that “four reflected waves are not received by any of the four ultrasonic vibrators”. Specifically, a set curvature of a bottom surface of the separator cup is set to be larger than a conventional set curvature. In addition, a distance from a center point of a bottom surface of the water tank of each of the four ultrasonic vibrators is set to be longer than a conventional distance.

A pass box configured to accommodate and decontaminate an article by concentrating a mist of decontamination agent on an article's surface and to reduce a duration of aeration operations. The box includes a decontamination chamber, an aeration chamber in which residue of the decontamination agent is removed from the article's surface, a decontamination agent supply device, a decontamination agent control device, a moving device configured to reposition the article, and an air supply and exhaust device. The decontamination agent supply device converts a chemical into the mist and supplies it into the decontamination chamber. The decontamination agent control device includes vibration boards that are adjacent to internal wall surfaces of the decontamination chamber and that are ultrasonically vibrated to generate sound flows in the vertical direction thereby pressing the mist with acoustic radiation to concentrate the mist on the external surfaces of the article.
