The invention relates to an aroma diffuser, more particularly to an aroma diffuser that is capable of effectively diffusing aroma within a relatively broad area and that has detachable components to facilitate maintenance and repair.
Therefore, the main object of the present invention is to provide aroma diffusers are capable of effectively diffusing aroma within a relatively broad area.
Another object of the present invention is to provide an aroma diffuser that has detachable components to facilitate maintenance and repair.
Accordingly, the aroma diffuser of this invention comprises a housing, a circuit-mounting frame and a fan unit.
The housing includes front and rear housing parts. The front housing part has an upper portion formed with an air outlet. The rear housing part has a rear wall with an upper portion and a lower portion. The lower portion of the rear wall has a carrier that extends transversely into the housing and that is adapted to support an aromatic preparation thereon.
The circuit-mounting frame is disposed inside the housing and is mounted on the upper portion of the rear wall. The circuit-mounting frame is adapted for mounting a power source thereon, and further has a control circuit mounted thereon. The control circuit is adapted to be connected electrically to the power source.
The fan unit includes a tubular collecting wall mounted on the circuit-mounting frame and disposed above the carrier. The tubular collecting wall has upper and lower wall portions. The upper wall portion has a front side formed with a radial air flow outlet that is registered with the air outlet of the front housing part. The lower wall portion has a fan device mounted therein and connected electrically to the control circuit. Aromatherapy diffuser is controlled by the control circuit so as to be adapted to draw aroma of the aromatic preparation on the carrier into the tubular collecting wall and so as to be adapted to blow the aroma inside the tubular collecting wall out of the air outlet of the housing via the radial air flow outlet of the tubular collecting wall.
