When the microcurrent of several tens mA flows through the DC current supply terminals "RTS" and "DTR", and the control signal of the control terminal "TxD" is "low", the switching transistor Q1 is "off". Therefore, the microcurrent is stored by the storage capacitor C2 while maintaining a constant voltage (for example, 5.6V). However, when the control signal of the control terminal "TxD" is "high", since the switching transistor Q1 is switched to "on", the electric charge stored in the storage capacitor C2 is the electric wire L1-solenoid valve ( 15)-wire L2-transistor Q1-capacitor C2 is discharged while making a closed loop to supply several hundred mA of operating current to the solenoid 15. In the present embodiment, the solenoid valve is taken as an example, but other types of valves may be spherical, and an injection device using a motor may also be used.

It will be easily understood by those skilled in the art that the above can be implemented by the fragrance spray device.

4 shows the voltage waveforms of the main points of the power supply circuit 100 of FIG. That is, if the current is continuously supplied from the terminals " RTS " and &quot; DTR &quot; for a predetermined time without the control signal being issued from the terminal " TxD " (i.e., 'low'), the switching transistor Q1 Off ', the microcurrents from the terminals &quot; RTS " and " DTR " flow through the diodes D1 and D2-capacitor C2 to the ground terminal " SG " The voltage at a constant potential (eg 5.6V) as in 4 (b) will be charged. At this time, if the control signal as shown in (a) of FIG. 4 is emitted from the terminal "TxD" (that is, "high"), as shown in (c) of FIG. 4, the switching transistor Q1 is turned "on". (I.e., V3 is 'high'), the voltage V2 stored in the capacitor C2 for storage flows to the wire L1-solenoid valve-wire L2-transistor Q1 and is discharged momentarily. Therefore, the solenoid valve operates to inject the fragrance, and when the control signal goes low again, the solenoid valve returns to the power storage cycle.

Although the present invention has been described above with reference to one embodiment shown in the accompanying drawings, the present invention is not limited thereto, and various modifications may be made within a range easily understood by those skilled in the art. For example, the microcurrent does not necessarily have to come from the mouse interface chip, and so does the control signal. In addition, as many switching elements as the switching transistor may perform the same function. Therefore, the limitation of the present invention should be limited only by the following claims.

As described above, according to the injector according to the present invention, since it is necessary to operate the injector by accumulating minute electric current flowing in the computer or the peripheral device, no separate power source is required, and an existing interface device can be retrofitted or added.
