2. Description of the Related Art FIG. 4 is a characteristic diagram of an aroma generating pattern in a conventional aroma generating device. As shown in this characteristic diagram, most of the conventional scent generating devices change the intensity of the scent diffused in the atmosphere in a predetermined cycle or pattern. For this reason, a timer is provided, and the intensity of the air flow sent to the aroma generating unit is continuously controlled by a fan based on the output of the timer to change the amount of the aroma component diffused in the air. Furthermore, the fan is controlled by a fan drive program that continuously controls the rotation speed of the fan in a predetermined pattern, the amount of air blown to the fragrance generating unit is adjusted, and the amount of the fragrance component diffused in the air is adjusted to the predetermined pattern. To continuously change the intensity of the scent.

Further, as a method of changing the intensity of the scent diffused in the air, there are the following methods depending on whether the shape of the fragrance is liquid, gel or granular.

(A) Natural diffusion method of liquid fragrance This method is to diffuse the scent rising from the liquid fragrance into the atmosphere by a fan, and the intensity of the fragrance emitted into the atmosphere controls the rotation speed of the fan. To adjust.

(B) Liquid Perfume Nozzle Spraying System In this system, the liquid perfume is sucked up by a siphon, atomized by the flow of air and discharged from the nozzle.
The intensity of the scent diffused in the atmosphere is adjusted by controlling the flow rate of air.

(C) Liquid fragrance ultrasonic spraying method This method supplies liquid fragrance onto an ultrasonic oscillator and discharges the liquid fragrance into fine particles into the atmosphere by ultrasonic vibration. The strength of the scent that diffuses inside is
The amount of liquid perfume supplied onto the ultrasonic vibrator or the vibration when the ultrasonic vibrator vibrates is controlled and adjusted.

(D) Natural diffusion method of gel-like fragrance In this method, the scent rising from the gel-like fragrance is diffused into the atmosphere by the fan, and the strength of the scent diffused in the atmosphere depends on the rotation speed of the fan. Control and adjust.

(E) Granular fragrance heating / diffusion system In this system, the granular fragrance is heated by a heater to diffuse the volatilized fragrance component into the atmosphere. The strength of the scent diffused in the atmosphere depends upon heating. Control and adjust the temperature of.

Generally, a fragrance is prepared by blending various natural scent extracts or chemically synthesized aroma components in a predetermined ratio and mixing these components in a solvent or a solid agent to prepare a liquid or gel form. Further, it is granular, and the characteristics of these blended aroma components when they volatilize vary depending on the temperature and humidity, and the flow rate and flow velocity of air when they are diffused in the atmosphere. Therefore, in the method of controlling the number of revolutions of the fan to change the flow rate and the flow velocity of the air in (A) the liquid natural fragrance natural diffusion method and (D) the gel fragrance natural diffusion method, the strength of the scent diffused in the atmosphere can be controlled. If the number of rotations of the fan is increased to increase the ratio, the ratio of the volatile fragrance components will be different, and there will be a problem that the scent will be different from that planned.

Further, in the (B) liquid perfume nozzle spray method and (C) liquid perfume ultrasonic spray method, the flow rate of air is increased or ultrasonic vibration is applied in order to increase the intensity of the scent diffused in the atmosphere. Increasing the amount of liquid perfume supplied onto the child or the amplitude when the ultrasonic vibrator vibrates causes the atomized liquid perfume particles to enlarge, and sticks to the walls and remains to generate residual aroma. It will be. Since this residual scent is mainly a volatile fragrance component, there is a problem that a scent different from the originally planned scent remains in the atmosphere.

The present invention has been made in order to solve the above-mentioned problems, and it is possible to faithfully diffuse the scent planned at this place into the atmosphere, and in a state close to nature without paralyzing the olfactory sense. An object of the present invention is to provide a scent generating device capable of diffusing an aroma into an atmosphere.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In FIG. 1, 1 is a random signal generation circuit that generates a random signal, 2 is a conversion circuit that converts the random signal generated by the random signal generation circuit 1 into a pulse signal whose pulse width changes randomly, and 3 is a scent generation unit. Yes, the scent is diffused into the atmosphere during the'H 'level period of the pulse signal output from the conversion circuit 2.

FIG. 2 is a cross-sectional view showing the structure of the fragrance generating section 3, in which the fragrance 5 is filled in the fragrance tank 4. 6
Is a cap that seals the scent diffusion port 4 a of the fragrance tank 4, and is fixed to one end of the plunger 7 of the solenoid 8. A space not filled with the fragrance is formed in the upper part of the fragrance tank 4, and the space is filled with the fragrance in which the ratio of the components is kept constant according to the volatilization ratio of each component constituting the fragrance. is doing. A solenoid drive circuit 9 amplifies the pulse signal supplied from the conversion circuit 2 by a solenoid drive transistor (not shown) to excite the solenoid 8.

Next, the operation will be described.

In this scent generating device, when a power switch (not shown) is turned on, the random signal generating circuit 1 generates a random signal. This random signal is generated based on white noise, or a pulse signal is generated using a shift register and a logic circuit that represent a random number or a function, and includes a 1 / f noise-like random signal. In this way, the random signal generated by the random signal generation circuit 1 is output to the conversion circuit 2.

In the conversion circuit 2, the random signal generation circuit 1
The random signal supplied from is converted into a pulse signal whose amplitude is constant and whose pulse width changes randomly.
Output to. FIG. 3A shows a pulse signal whose pulse width changes randomly.

This pulse signal is output to the scent generating unit 3, and the solenoid drive circuit 9 of the scent generating unit 3 excites the solenoid during the'H 'level of the pulse signal. As a result, the plunger 7 of the solenoid 8 is sucked, the cap 6 that has sealed the diffusion port 4a of the fragrance tank 4 is opened, and the fragrance diffuses into the atmosphere. In this case, the fragrance diffused in the atmosphere is the fragrance filled in the space in the fragrance tank 4, and the fragrance is kept constant in proportion according to the volatilization ratio of each component constituting the fragrance.

Since this embodiment is constructed as described above, the pulse signal for exciting the solenoid 8 has a constant amplitude and a random pulse width, so that the aroma diffuses from the diffusion port 4a into the atmosphere. The pattern will be random, and the fragrance in the atmosphere will be extremely natural without paralyzing the sense of smell.

Further, the fragrance filled in the space in the fragrance tank 4 is naturally diffused instead of forcibly diffusing the fragrance into the atmosphere by using a fan or an ultrasonic vibrator, so that the fan or the ultrasonic wave is used. Like when the flavor is forcedly diffused into the atmosphere using a vibrator, the proportion of the volatile fragrance component is different, resulting in a different fragrance than planned at this place, or a liquid flavor that is atomized The particles of swell and become attached to the wall and remain and generate a residual scent, and the scent different from the scent planned for this time does not remain in the atmosphere.
Even if a fan or an ultrasonic vibrator is used to forcibly diffuse the fragrance, the air flow rate and the flow velocity are constant, and the amplitude of the ultrasonic vibrator is also constant. The ratio of the ingredients is almost constant, and it is possible to diffuse the scent that we planned.

As another embodiment, the random signal supplied from the random signal generating circuit 1 is shown in FIG.
The pulse signal may be converted into a pulse signal whose amplitude is constant and whose pulse period changes randomly. Even with such a configuration, the same effect as the above effect is produced.

[0023]

As described above, according to the present invention, a pulse signal whose pulse width changes randomly or a pulse signal whose pulse period changes randomly is converted, and the'H 'level of the converted pulse signal or Since the aroma is diffused in the atmosphere according to the state of'L 'level, the scent generation period or generation cycle changes randomly and does not paralyze the olfactory sense. Can be diffused inside.
