The present invention relates to a scent diffuser, and more particularly to the scent diffuser using a bottle which diffuses scents quickly after spraying and atomizing aromatic liquid by using the diffusing device.
A conventional aroma diffuse is disclosed in U.S. Pat. No. 9,539,355, but its structure is complicated and has a large size. A conventional detachable aromatic nebulizing diffuser is disclosed in U.S. Pat. No. 7,963,460 and contains a fan configured to deliver scents toward an external space, but it consumes power of two electric devices. A lamp-based scent releasing system is disclosed in U.S. Pat. No. 8,201,957 and contains a heating element configured to heat aromatic substance, for example, an electric resistance heats the aromatic substance so as to diffuse scents, thus causing power consumption and heating danger.
The present invention has arisen to mitigate and/or obviate the afore-described disadvantages.
The primary aspect of the present invention is to provide a scent diffuser using a bottle which diffuses scents quickly after spraying and atomizing aromatic liquid by using the diffusing device.
To obtain the above aspect, a scent diffuser using a bottle provided by the present invention contains: a body, a power connection unit, a pump, and a diffusing device.
The body includes an accommodation chamber defined in the body and a first opening formed on a top of the accommodation chamber.

The diffusing device is accommodated in an upper end of the body, and the diffusing device includes a cap, a nozzle, a spraying member, a holder, and a spray hose.
The cap has a first orifice, a second orifice, and a third orifice, the second orifice is formed on a top of the cap and communicates with the outflow segment of the pump, and the third orifice is formed on a bottom of the cap and communicates with the second orifice.
The spraying member has a receiving groove, a suction mouth, and an outlet, wherein the receiving groove is defined in the spraying member, the outlet communicates with a first side of the receiving groove, and the suction mouth is in communication with a second side of the receiving groove.
The nozzle has a shrinkage conduit and a narrow conduit, the shrinkage conduit communicates with the narrow conduit, the spraying member is connected in the holder, the nozzle is accommodated in the receiving groove of the spraying member, a slit is defined between the nozzle and the receiving groove, and a free end of the narrow conduit is proximate to the outlet;
The holder has a connection portion arranged on a side of the holder.
The cap is coupled on a top of the holder, the third orifice of the cap communicates with an upper end of the nozzle, and the first orifice of the cap communicates with an interior of the diffusing device and an exterior outside the diffusing device. A first side of the spray hose communicates with the first orifice, and a second side of the spray hose is in communication with an external environment outside the scent diffuser.
With reference to
a power connection unit 3 housed in the accommodation chamber 11 of the body 1;
a pump 5 including an air inflow segment 51 and an air outflow segment 53, and the pump 5 being housed in the accommodation chamber 11 of the body 1 and electrically connected with the power connection unit 3 so as to pump gas successively;
a diffusing device 7 accommodated in an upper end of the body 1, and the diffusing device 7 including a cap 71, a nozzle 73, a spraying member 75, a holder 77, and a spray hose 79;
the cap 71 having a first orifice 711, a second orifice 713, and a third orifice 715, wherein the second orifice 713 is formed on a top of the cap 71 and communicates with the outflow segment 53 of the pump 5, and the third orifice 715 is formed on a bottom of the cap 71 and communicating with the second orifice 713;
the spraying member 75 having a receiving groove 751, a suction mouth 753, and an outlet 755, wherein the receiving groove 751 is defined in the spraying member 75, the outlet 755 communicates with a first side of the receiving groove 751, and the suction mouth 753 is in communication with a second side of the receiving groove 751;
the nozzle 73 having a shrinkage conduit 731 and a narrow conduit 733, wherein the shrinkage conduit 731 communicates with the narrow conduit 733, the spraying member 75 is connected in the holder 77, the nozzle 73 is accommodated in the receiving groove 751 of the spraying member 75, a slit 757 is defined between the nozzle 73 and the receiving groove 751, and a free end of the narrow conduit 733 is proximate to the outlet 755;
the holder 77 having a connection portion 771 arranged on a side of the holder 77;
wherein the cap 71 is coupled on a top of the holder 77, the third orifice 715 of the cap 71 communicates with an upper end of the nozzle 73, and the first orifice 711 of the cap 71 communicates with an interior of the diffusing device 7 and an exterior outside the diffusing device 7; a first side of the spray hose 79 communicates with the first orifice 711, and a second side of the spray hose 79 is in communication with an external environment outside the scent diffuser 100.
A bottle 9 is connected with the diffusing device 7 by way of a sucking tube 90, the bottle 9 includes the sucking tube 90 and a second opening 91 configured to removably connect with the connection portion 771 of the holder 77. The bottle 9 is configured to accommodate aromatic liquid, and the sucking tube 90 is housed in the bottle 9 and a free end of the sucking tube 9 is coupled with the suction mouth 753.
The power connection unit 3 is in connection with a power supply so as to drive a pump 5 to successively pump the gas toward the shrinkage conduit 731 via the second orifice 713 and the third orifice 715, thus accelerating a flow speed of the aromatic liquid in the shrinkage conduit 731 of the nozzle 73. Thereafter, a flow of the gas sprays out of the outlet 755 of the receiving groove 751 via the narrow conduit 733 and flows through the suction mouth 753 at a highest flow speed so as to produce a pressure difference of the aromatic liquid around the suction mouth 753, thus providing a suction force to the sucking tube 90. Then, the aromatic liquid is drawn into the receiving groove 751 from the bottle 9 via the suction mouth 753 and is sprayed out of the outlet 755 from the receiving groove 751 by the gas from the nozzle 73, thus diffusing the scents by using Venturi effect. For example, the gas is successively delivered and sprayed out the narrow conduit 733 at the highest flow speed via a small-diameter portion of the shrinkage conduit 731 so that a flow speed of the gas increases because of a change (such as from the shrinkage conduit 731 to the narrow conduit 733) of a cross-sectional area of the nozzle 73 and a pressure decreases. The gas sprays out of the outlet 755 through the suction mouth 753 so as to produce a pressure drop (a pressure difference) around the suction mouth 753, thus drawing the aromatic liquid to the suction mouth 753 via the sucking tube 90. Thereafter, the aromatic liquid flows into the slit 757 of the nozzle 73 and is atomized and sprayed to the first orifice 711 and the spray hose 79 by a high-speed gas of the receiving groove 751 and the nozzle 73 from the outlet 755, thus diffusing the scents.
Accordingly, the scent diffuser of the present invention diffuses the scents by pumping the gas to the diffusing device 7. Preferably, the bottle 9 is removable from the connection portion 771 of the holder 77, thus replacing the bottle 9 quickly.
Referring to
The aromatic liquid is any one of essential oil, fragrance oil, essence, flower essence, perfume, and fragrance agent so as to produce the scents quickly after being atomized.
