Provided is a discharge apparatus for an air vehicle, capable of reducing a loss of discharge pressure from an aerosol container. The discharge apparatus for an air vehicle discharges contents from an aerosol container 10 mounted on an airframe 101 through a nozzle 15. The aerosol container 10 is mounted on an exterior of the airframe 101, and one end of the nozzle 15 is supported by a discharge end part of the aerosol container 10 via a pipe joint 17 that allows the nozzle 15 to rotate so as to be rotatable around at least one rotation axis M.

A microporous vaporization assembly includes: a microporous vaporization plate for vaporizing an aerosol-generation substrate to generate aerosols; and a circuit board flexibly electrically connected to the microporous vaporization plate, the circuit board transmitting an electrical signal of the circuit board to the microporous vaporization plate. In an embodiment, the microporous vaporization assembly includes a flexible electrical conductor between the circuit board and the microporous vaporization plate. The flexible electrical conductor is in contact with the circuit board and the microporous vaporization plate respectively, to implement a flexible electrical connection between the circuit board and the microporous vaporization plate.

The humidifier includes a humidification section which vaporizes water to produce humidified air, and a fan which produces in an air passage an air flow delivering the humidified air to the outside. The humidifier further includes a sterilized water producing section which produces sterilized water, an ultrasonic irradiator which produces sterilizing mist through ultrasonic irradiation of the sterilized water, an auxiliary passage through which the sterilizing mist is delivered to the outside, and an operation switching mechanism. The operation switching mechanism is switched between a first operation mode in which the air passage and the auxiliary passage communicate with each other to introduce the sterilizing mist into the air passage, and a second operation mode in which communication between the air passage and the auxiliary passage is blocked.

A microporous vaporization assembly includes: a piezoceramic plate, a through hole being provided in the piezoceramic plate; and a vaporization plate including a body part and a fence part, the body part being stacked on and bonded to the piezoceramic plate and covering the through hole, a plurality of vaporization holes being provided in an area of the body part corresponding to the through hole. The fence part is arranged protruding from a surface of the body part stacked with the piezoceramic plate and surrounds an outer circumference of the piezoceramic plate.

A photo-resist (21) is applied in a pattern or vertical columns having the dimensions of holes or pores of the aperture plate to be produced. This mask pattern provides the apertures which define the aerosol particle size, having up to 2500 holes per square mm. There is electro-deposition of metal (22) into the spaces around the columns (21). There is further application of a second photo-resist mask (25) of much larger (wider and taller) columns, encompassing the area of a number of first columns (21). The hole diameter in the second plating layer is chosen according to a desired flow rate.

A method for aerosolising a liquid comprises the steps of: —providing an aperture plate having at least 100 outlet holes per mm; delivering liquid to the aperture plate; and vibrating the aperture plate to produce an aerosol. The viscosity of the liquid is in the range of from 1 to 15 cP and the surface tension of the liquid is in the range of from 72 to 0.5 mN/m. The output rate of the generated aerosol is greater than 0.01 mL/min.

A humidifier includes a container for containing a fluid; a cartridge for nebulizing the fluid, the cartridge configured to be fixed inside the container, the cartridge including a cartridge housing including a bottom side that is configured to contact a bottom of the container, a top side opposite to the bottom side; a back side; a front side; a left side; and a right side; and a handle on the top side of the cartridge housing, the handle projecting upward and away from the cartridge housing.

There is provided a nebulizer (2), comprising a first plate (20) configured to hold a transducer (14); a second plate (22) having an aperture therein, the first plate being positioned on a first side of the second plate such that the transducer is adjacent the aperture; and a third plate (24) configured to hold a mesh plate through which liquid can pass to form droplets, the third plate being positioned on a second side of the second plate opposite the first side such that the mesh plate (16) is adjacent the aperture, with the aperture, transducer and mesh plate forming a cavity for holding liquid to be nebulized. A method for manufacturing such a nebulizer is also provided.

An aperture plate (1) is attached at its rim (203) to a support washer (3) by adhesive. Anchor grooves (204) having a zig-zag pattern in plan are machined in the lower surface of the rim (203 of the aperture plate before application of the adhesive. The grooves (204) extend out to the edge of the aperture plate (1). The anchor grooves have a depth in the range of 10 μm to 40 μm, and a width in the range of 20 μm to 150 μm, and an angular pitch in the range of 2.5° to 12.5°. Excellent bonding strength is achieved for long term reliable attachment in an environment of high frequency vibration and moisture and chemical corrosion.
