BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention generally relates to portable communication devices such as mobile phones, and more particularly to a portable communication device which has a fragrance dispensing apparatus therein.
2. Prior Art
Currently, portable electronic communication devices provide a variety of means for notifying (cuing) the user of a new incoming call or message. For example, the portable communication device may sound a ring tone, play music, or vibrate. However, if the user is in a meeting or on a noisy street, he/she may not hear the ring tone or music. In addition, if the portable communication device is not beside the user's body, he/she may not feel the vibration.
A mobile phone employing a unit storing fragrance therein can be found in an International Patent No. WO/0215541 issued to Andreas Wuellner and published on Feb. 21, 2002. Using fragrance is an alternative way to cue the user to an incoming call. These mobile phones typically comprise an interchangeable unit provided to couple with mobile support elements. The interchangeable unit is able to store fragrant liquid and release the corresponding fragrance into the environment. Thus when an incoming call is received by a mobile phone, the fragrance can be release into the environment to cue the user. However, this fragrance cuing function does not enable the user to ascertain who the caller is.
Therefore, a portable communication device with fragrance cuing which can differentiate among incoming callers is desired.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide a portable communication device having a fragrance dispensing apparatus therein, which can cue a user regarding different incoming callers using different fragrances.
To achieve the above object, a portable communication device comprises a body including a container. The body houses main circuitry therein. A pair of fragrance dispensing apparatuses is housed in the container. The container also houses a plurality of electrical connectors therein. The electrical connectors are electrically connected with the main circuitry. Each fragrance dispensing apparatus includes a vessel, and each vessel has a nozzle. Each nozzle includes a heater connecting with and being enabled by the main circuitry via the corresponding electrical connector. When the portable communication device receives an incoming call (or message), a predetermined one of the heaters is enabled by the main circuitry to dispense a fragrance corresponding to the caller (or sender).
Other objects, advantages and novel features of the invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings, in which:

DETAILED DESCRIPTION OF THE INVENTION
A portable communication device in the preferred embodiment of the present invention is a mobile phone 10. Referring to FIGS. 1 and 2, the mobile phone 10 includes a body 11 and two fragrance dispensing apparatuses 12.
The body 11 includes a container 111 in one end thereof, a container cover 112 rotatably mounted on said end by a hinge (not labeled), and a pair of holes 113 defined in a main wall of the body 11 at the container 111. The container 111 defines an opening (not labeled) in said end of the body 11 at the hinge. The container 111 includes a plurality of pedestals (not shown) in a bottom thereof, and a plurality of electrical connectors (not shown) is provided on the pedestals. The electrical connectors are electrically coupled with main circuitry (not shown) of the mobile phone 10 in the body 11. The cover 112 is hinged near the opening of the container 111, and can cover the opening. The fragrance dispensing apparatuses 12 are received in the container 111, fixed on the pedestals, and covered by the cover 112. Each fragrance dispensing apparatus 12 engages with a corresponding one of the electrical connectors, so that it is electrically connected with the main circuitry of the mobile phone 10.
Referring to FIGS. 3 and 4, each fragrance dispensing apparatus 12 includes a vessel 121 containing a core 125 therein. The vessel 121 also includes an entrance 123 in a top thereof, and at least one nozzle 127 at a bottom thereof. The core 125 is made of a material which has good liquid absorbing capability. An inner end of the nozzle 127 is embedded in the core 125, and an outer end of the nozzle 127 has an opening in a sidewall of the vessel 121. Fragrant liquid is stored in the core 125. When the fragrant liquid is completely used up, a user can insert new fragrant liquid into the core 125 with an injector.
Referring to FIG. 5, the nozzle 127 comprises a heater 128 in a wall thereof. In the preferred embodiment, the heater 128 is a resistance heater. When the fragrance dispensing apparatus 12 is installed in the container 111, the heater 128 is connected with one of the electrical connectors. The main circuitry of the mobile phone 10 can thus send out a pulse signal 1006 (see FIG. 10) to enable the heater 128. In general, the nozzle 127 is full of fragrant liquid. The nozzle 127 is very thin, so that the fragrant liquid is retained therein without effusing out.
Referring to FIGS. 6, 7 and 8, when the heater 128 is enabled by a pulse signal 1006, the temperature of the heater 128 rises to 300 degrees Centigrade immediately. Some of the fragrant liquid near the heater 128 changes to fragrant gas and expands. The gas pushes some of the fragrant liquid near the opening of the nozzle 127 out through the opening. This fragrant liquid then exits the mobile phone 10 through a corresponding one of the holes 113. In addition, because the pulse signal 1006 is very short and the heating temperature is high, the gas near the heater 128 rapidly expands, so that it obstructs liquid located far from the opening from reaching the opening. Thus only a predetermined amount of the fragrant liquid is released from the opening, with no wastage.
Referring to FIG. 9, the user programs the mobile phone 10 so that each of pre-identified senders is assigned a particular fragrance according to fragrant liquid contained in a corresponding fragrance dispensing apparatus 12. The function of cuing the user regarding incoming calls according to fragrance is thus enabled. In the following description, it will be assumed that any incoming call (or message) is from a pre-identified caller (or sender), and not from a previously unknown caller (or sender). When an incoming call arrives at the mobile phone 10, the main circuitry controls the fragrance dispensing apparatuses 12 as follows. First, in step S901, the main circuitry determines whether there is an incoming call. If there is no incoming call, the procedure is ended. If there is an incoming call, in step S902, the main circuitry identifies who the caller is. Then in step S903, the main circuitry sends a pulse signal 1006 to the nozzle 127 of a corresponding fragrance dispensing apparatus 12. Next, in step S904, the main circuitry determines whether there is a signal or answering message which indicates that the user has acknowledged the incoming call. If the user has not acknowledged the incoming call, the procedure returns to step S903. If and when the user has acknowledged the incoming call, in step S905, the main circuitry disables the nozzle 127 of the corresponding fragrance dispensing apparatus 12, whereupon the procedure is ended. In other words, until the user acknowledges the incoming call, the nozzle of the corresponding fragrance dispensing apparatus 12 is continually enabled by pulse signals 1006, so that the nozzle 127 emits enough fragrance for the user to be successfully cued regarding the incoming call.
Referring to FIG. 10, the main circuitry includes incoming call identifying circuitry 1001, selective circuitry 1003, and pulse-generating circuitry 1005. In step S902 described above in relation to FIG. 9, the incoming call identifying circuitry 1001 sends out a control signal 1002 to the selective circuitry 1003. Then in step S903, the selective circuitry 1003 sends out a pulse signal 1004 to a corresponding one of the nozzles 127, i.e. A1 or A2 (or An in the case where there may be more than two fragrance dispensing apparatuses 12 with nozzles 127), and to the pulse-generating circuitry 1005. Then the pulse-generating circuitry 1005 sends out a pulse signal 1006 to enable the heater of the corresponding nozzle 127.
It is to be understood that in various alternative embodiments of the present invention, the container 111 may be provided in the body 11 in any suitable position. Further, one, three, or more fragrance dispensing apparatuses 12 may be employed. When two or more fragrance dispensing apparatuses 12 are employed, they may be separately distributed in the body 11, or they may be integrated together. Further, the described electrical connectors may be integrated into a single electrical connector.
It is believed that the present invention and its advantages will be understood from the foregoing description, and it will be apparent that various changes may be made thereto without departing from the spirit and scope of the invention or sacrificing all of its material advantages. The examples hereinbefore described are merely preferred or exemplary embodiments of the invention.
