Abstract: A detachable aromatic nebulizing diffuser includes a base panel, an electric fan, a fluid container, an ultrasonic oscillator, a power jack, a water baffle, a lower housing and a top cover. The ultrasonic oscillator oscillates ultrasonic waves to cause an aromatic fluid in the fluid container into a fine mist that is carried by currents of air caused by the electric fan and guided through an air duct in the fluid container. The fluid container has bottom mounting rods detachably plugged into respective tubular upright posts of the base panel, facilitating mounting and dismounting. The water baffle and the top cover are light transmissive for creating a visual effects upon working of a light source that is carried on the ultrasonic oscillator.

Abstract: An aromatic nebulizing diffuser includes a base panel, an electric fan, a power control unit, a lower housing, a fluid container that has bottom mounting rods detachably plugged into respective tubular upright posts of the base panel to facilitate cleaning work, a water baffle, an upper housing, an ultrasonic oscillator that controls a light source to emit light when oscillating an aromatic fluid in the fluid container to produce a fine mist of aromatic fluid droplets and a speaker mounted in a vertical speaker holder at the bottom side of the fluid container within the lower housing and controllable by the power control unit for audio output.

Abstract: A high-safety, high-performance aromatic nebulizing diffuser capable of producing sound and lighting effects is disclosed to include a base panel, an electronic control unit, a speaker, an electric fan, a fluid container, an ultrasonic oscillator, a fluid intake control device set in between the oscillation chamber and the fluid container, a dip tube in communication between the oscillation chamber and the fluid container and changeable between an open status and a close status to control the fluid intake control device in closing/opening the passage between the oscillation chamber and the fluid container, an outer housing, a holder defining an oscillation chamber at the top and a cover at the bottom, an air passage in air communication between the oscillation chamber and the cover for the passing of currents of air caused by the electric fan, an exhaust passage for guiding a generated fine mist of aromatic fluid droplets out of the oscillation chamber into the atmosphere.

Abstract: An aromatic nebulizing diffuser includes a base panel, a lower housing, power adapter, an electric fan, a speaker, a music control circuit, an ultrasonic oscillator carrying a light source, a fluid container, a waster shutter and a transmissive cover. When electrically connected, the ultrasonic oscillator is started to generate high frequency sound waves and to cause atomization of the aromatic fluid contained in the fluid container so that a mist of aerodynamic breakup of fine water drops is seen through the transmissive cover and at the same time, the music control circuit outputs a music through the speaker and the light source emits a mixed color of light to light up the mist of aerodynamic breakup of fine water drops that is forced out of the hole on the top side of the transmissive cover.

Abstract: A light-emitting smell-altering aroma dispenser includes a casing having a bottom opening blocked by a base member, heater members supported on trays above a control circuit board in the casing, tubular aroma containers inserted through the top wall of the casing into the heater members at the trays and holding a respective aromatic substance for heating by the heater members to release a pleasant smell subject to the control of the control circuit board, and light emitting devices controlled by the control circuit board to emit light toward the aroma containers when the aroma substance in the aroma containers is being heated to release a pleasant smell.

Abstract: Adjustable riser pipe to be used for instance in a coffee maker with two containers sealingly arranged relative to and above one another, said two containers being flow-connected through the adjustable riser pipe in such a manner that liquid water can be caused to leave the closed lower container and enter the upper container through said riser pipe by means of pressure resulting from a heating until the rising of liquid water is stopped because the water level reaches a limit level defined by a level set by the lower edge of the riser pipe. The Adjustable riser pipe (7) according to the invention is formed by a main pipe (2) and by a sleeve (6) being substantially sealingly and axially and axially and/or circumferentially displaceable about said main pipe. The main pipe (2) fixedly and tightly abuts a structure (4) in the upper container (1) at an unchangeable distance from said upper container and in a direction towards the lower edge (5) of the main pipe.
