Abstract:
An aroma diffuser comprising:a housing including front and rear housing parts, said front housing part having an upper portion formed with an air outlet, said rear housing part having a rear wall with an upper portion and a lower portion, said lower portion of said rear wall having a carrier that extends transversely into said housing and that is adapted to support an aromatic preparation thereon;a circuit-mounting frame disposed inside said housing and mounted on said upper portion of said rear wall, said circuit-mounting frame being adapted for mounting a power source thereon, said circuit-mounting frame further having a control circuit mounted thereon, said control circuit being adapted to be connected electrically to the power source;a fan unit including a tubular collecting wall mounted on said circuit-mounting frame and disposed above said carrier, said tubular collecting wall having upper and lower wall portions, said upper wall portion having a front side formed with a radial air flow outlet that is registered with said air outlet of said front housing part, said lower wall portion having a fan device mounted therein and connected electrically to said control circuit, said fan device being controlled by said control circuit so as to be adapted to draw aroma of the aromatic preparation on said carrier into said tubular collecting wall and so as to be adapted to blow the aroma inside said tubular collecting wall out of said air outlet of said housing via said radial air flow outlet of said tubular collecting wall;slidable fan unit retaining means, provided on said tubular collecting wall and said circuit-mounting frame, for mounting slidably and removably said tubular collecting wall on said circuit-mounting frame, said slidable fan unit retaining means cooperating with said circuit-mounting frame to arrest forward and rearward movement of said tubular collecting wall relative to said circuit-mounting frame;upper limiting means, provided on said circuit-mounting frame, for limiting upward movement of said tubular collecting wall relative to said circuit-mounting frame; andresilient lower limiting means, provided on said circuit-mounting frame and engaging releasably said tubular collecting wall, for limiting downward movement of said tubular collecting wall relative to said circuit-mounting frame.
