A venturi inhalation device is provided. The device has a tube defining an internal volume with a fine bore needle disposed at one end. The fine bore needle is in fluid communication with the internal volume of the tube such that medication stored therein can pass into the needle. The tube has a second end which can be sealed to contain the medication until the device is used. A hollow housing is sized and shaped to receive the tube in close tolerance, whereupon the tube being so received, an air-tight seal is formed. The housing also includes a venturi restriction, and when the tube is received by the first end of the housing, a distal end of the fine bore needle is placed within the venturi restriction. A mouthpiece is disposed on a second end of the housing enabling a user to inhale the medication in the tube.

The rotary shaft is rotated by a rotary motor and is disposed in the vertical direction. The pumping pipe includes a lower portion having a pumping port and an upper portion fixed to the rotary shaft, and is rotated in coordination with rotation of the rotary shaft to pump up water through the pumping port and centrifugally discharge the water. The pumping pipe generates, inside the pumping pipe, a whirlpool in the water in the reservoir by the rotation, and forms, at the center of the whirlpool, a void providing communication between the pumping port and the drain port.

An aroma diffuser comprises a host and an aromatherapy nebulizer; the host has an air pump received therein; the air pump has an air inlet port and an air outlet port; the aromatherapy nebulizer comprises a nebulizer cap and an essential oil bottle with a dip tube extending from the nebulizer cap into the essential oil bottle for sucking liquid essential oil up. The host sets a mounting ring extending outwards from a sidewall thereof, the aromatherapy nebulizer is installed in the mounting ring in such way that the aromatherapy nebulizer is able to be plugged in or pulled out up and down through the mounting ring, thereby the aromatherapy nebulizer is installed externally to the host.

The invention relates to a device (1) for releasing an aerosol, comprising a cylindrical upper housing (3) with a cylindrical top protrusion (30) extends downwards from the top wall (32) so that a predetermined space (34) is formed between the circumferential inner side of the upper housing and the outer side of the cylindrical top protrusion (30), wherein the top protrusion (30) comprises a bolt (18) protruding downwards from the bottom end (36) of the top protrusion, and wherein the upper housing (3) comprises at least one opening (7) for releasing the dispersed aerosol, a cylindrical lower housing (2) with a bottom floor (9), further including an bottom opening (5) in the bottom floor (9) of the lower housing (2), a cylindrical bottom protrusion (13) enclosing the bottom opening (5) and protruding upwards so that a predetermined space (11) is provided between the inner side of the lower housing (2) and the outer side of the cylindrical bottom protrusion (13) forming a reservoir for the aerosol, a support frame (15) fixedly connected to the inner side of the bottom and/or the side of the lower housing (2); and a float (12) that covers the cylindrical bottom protrusion (13), wherein the inner circumferential shape of the float (12) matches the outer shape of the cylindrical bottom protrusion (13) and wherein the float (12) is supported by the support frame (15) so that the distance C between the bottom protrusion (13) and the float (12) is essentially the same over the whole circumference, wherein the distance T of the top end of the float (12) to the inner side of the top end of the cylindrical bottom protrusion (13) is greater than the respective circumferential distance C.

An ultrasonic atomizer including a shell, a sealing cover, a base, a through pipe, an outer connecting ring, an inner connecting ring, an outer loudspeaker cover, a butt-joint pipe, an inner loudspeaker cover and an atomization mechanism, wherein the through pipe is arranged on the shell, the outer connecting ring is arranged at a corresponding position of the through pipe, the inner connecting ring is arranged inside the through pipe, the outer loudspeaker cover is arranged inside the shell, and an end portion of the outer loudspeaker cover penetrates out of the sealing cover and extends outside so as to be connected with the base, the butt-joint pipe is arranged inside the through pipe, the inner loudspeaker cover is connected with an end portion of the butt-joint pipe, and the atomization mechanism is arranged inside the base.

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.
