An angle-adjustable aroma diffuser includes a housing defining opposing first opening and second opening, a aroma container mounted in the housing, a resistor attached to the bottom side of the aroma container, an aroma device put in the aroma container, and an electric plug pivotally coupled to the second opening of the housing and electrically connected with the resistor and connectable to an external power socket for conducting electricity to the resistor to produce heat so that the aroma container can transfer produced heat to the aroma device, causing the aroma device to give off a pleasant smell.

A combination aroma diffuser includes a lower housing, a control unit, a display screen, an upper housing, a light-emitting heating unit, a cover member and a speaker. The upper housing and the lower housing admits light so that the displayed digits of the display screen that is kept inside the lower housing are visible when the display screen emits light. The control unit has stored therein music and sounds for output through the speaker. The light-emitting heating unit emits light through the upper housing to heat an aromatic fluid in the cover member into vapor that goes out of air vents of the cover member to the outside open air.

A lamp-based aroma diffuser using an aroma capsule is disclosed to include a lamp housing, a hollow light-transmissive shade mounted in the lamp housing, a holder member mounted in the lamp housing, a heat conduction device mounted in the holder member, a heating element kept in contact with the bottom wall of the heat conduction device, a light-emitting device, and a power supply device-incorporated PC board for driving the heating element to heat the heat conduction device and a replaceable aroma diffuser in the heat conduction device and the light-emitting device to emit color light through the hollow light-transmissive shade and the lamp housing.

An embodiment of the invention provides an air treatment device. The air treatment device comprises an air purifying unit configured to purify air; a scent dispenser configured to dispense scent; an air detector, configured to detect the purified air and provide an output signal; and a processor configured to receive the output signal from the air detector and control the operation speed of the air purifying unit and the dispensing flow of scent dispensed by the scent dispenser, based on the output signal, wherein the dispensing flow of scent dispensed by the scent dispenser is decreased with the increase of the operating speed of the air purifying unit. Another embodiment of the invention provides a method of controlling a scent dispenser and an air purifying unit of an air treatment device, wherein the air treatment device further includes an air detector and a processor. The method comprises the steps of purifying air by using the air purifying unit; detecting the purified air by using the air detector; controlling, by using the processor, the operating speed of the air purifying unit and the dispensing flow of scent dispensed by the scent dispenser, based on the detection result, wherein the dispensing flow of scent dispensed by the scent dispenser is decreased with the increase of the operating speed of the air purifying unit.
