Description

[Detailed explanation of the idea] [Industrial application field] The present invention relates to an aroma generating device.

[Prior art] Conventionally, as an aroma generating device, for example,
-As disclosed in Publication No. 198086, a case containing an air freshener is provided with a fragrance release port, and when the fragrance is released, a fan installed inside the case is rotated and the fragrance is released from the fragrance release port to the outside. Some are known to emit aromas.

In addition, in Japanese Utility Model Publication No. 56-39038, a fan is rotated by pulling up a chain by hand and pulling down a weight, and a door-shaped damper is opened using the wind pressure generated by the rotation of the fan to create an aromatic fragrance. A device is disclosed for opening respective vents for ejection and air inflow.

[Problems to be Solved] In the first conventional example, the fragrance constantly leaked out little by little from the fragrance release port even when there was no need to release the fragrance. For this reason, the air freshener wears out quickly, and when this fragrance generating device is incorporated into an alarm clock to emit a fragrance at the alarm set time, even if the fan is rotated to emit the fragrance, the user will not be able to use it normally. Since people got used to the fragrance, they did not receive much olfactory stimulation, and the effect was low.

Furthermore, in the second conventional example, the power for opening the through hole was dependent on wind pressure, and therefore reliability was poor. In particular, it was difficult to open the air intake holes, which posed a practical problem. Furthermore, since the fan that releases the fragrance to the outside was manually rotated, it was naturally impossible to apply it to an alarm clock.

Therefore, the purpose of the present invention is to generate fragrance only when needed without normally leaking fragrance, thereby minimizing the consumption of fragrance and emphasizing the fragrance release effect. To provide an aroma generating device equipped with a mechanism for reliably emitting an appropriate amount of aroma to the outside.

Another object of the present invention is to provide an alarm clock that uses the above-mentioned fragrance generating device to provide a refreshing wake-up using a fragrance in addition to a normal alarm.

[Means for Solving the Problems] The fragrance generating device according to the present invention has an air freshener storage compartment formed in the upper part of the case so that an air freshener can be stored therein, and communicating with the inside of the case through a communication port. a first lid body which is provided so that the upper part of the air freshener storage part can be opened and closed, an air intake port that is opened in a part of the case, and a first lid body that is provided that the air intake port can be opened and closed. a second lid, a fan provided in the case and rotationally driven by a drive motor, a drive lever that is displaced by an electromagnetic device when the drive motor is activated, a first lid and a second lid; It has a pair of engaging parts that respectively engage with the lid bodies, and in conjunction with the displacement of the drive lever, both the engaging parts open the first lid body and the second lid body. It is equipped with an engagement lever that is held in place.

Further, the alarm clock according to the present invention is equipped with the above-described fragrance generating device and an alarm generating device, and is characterized in that the fragrance generating device is activated a certain period of time before the activation of the alarm generating device. do.

[Function] Normally, the fragrance storage section and the air intake port are sealed from the outside by the first and second lids to prevent fragrance from leaking. When releasing the fragrance, the fan is rotated by the drive motor, and
An engaging lever is driven by an electromagnetic device and a driving lever, and the first and second lid bodies that engage with the pair of engaging parts are opened by the engaging lever, and the air freshener storage section and the air intake port are opened. to open. As a result, when the fragrance is released, the air containing the fragrance that fills the case is released to the outside from the fragrance release port by the rotation of the fan, and at the same time, outside air flows into the case from the air intake port.

Normally, the air intake port 5c and the aroma discharge port 12b are sealed by the first lid body 13 and the second lid body 8 to prevent the aroma from leaking to the outside.

At a certain time before the alarm generator (not shown) is activated, the drive motor 6 turns on the fan 7.
As the coil 19 rotates, the coil 19 is energized.
By energizing the coil 19, a magnetic repulsion force against the permanent magnet 22 is generated in the electromagnet device 20. When receiving the magnetic repulsive force, the drive lever 21 is elastically deformed with one end fixed to the protrusion 16a of the yoke 16, and the engagement lever 23 interlocked with the drive lever 21 moves upward. Thereby, the first lid 13 and the second lid 8 are opened, and the air intake port 5c and the aroma discharge port 12b are opened.

Therefore, the air containing the aroma is discharged to the outside from the aroma discharge port 12b by the rotation of the fan 7.
At the same time, outside air flows into the case 3 from the air intake port 5c.

Note that the time difference between the activation of the aroma generator and the activation of the alarm generator can be set as appropriate.

[Effect] As described above, according to the present invention, the fragrance does not normally leak and the fragrance can be released only when necessary, so the user receives strong olfactory stimulation and the effect of releasing the fragrance is high. be. Since the first lid and the second lid can be reliably held in the open state by the electromagnetic device, the drive lever, and the engagement lever, the fragrance can be stably released in an appropriate amount using weak wind power. The amount of fragrance released can be set completely freely by changing the time period for supplying power to the electromagnetic device. Similarly, since the rotational force of the fan can be adjusted depending on the supplied power, the degree of fragrance release can also be adjusted freely.

Additionally, since the case is usually kept in a sealed state, consumption of the fragrance is minimized, making it economical.

If this fragrance generator is installed in an alarm clock and activated a certain period of time before the alarm is activated, the alarm will sound after the fragrance is released and the user receives a pleasant olfactory stimulation. The sound resonates, so you can wake up feeling refreshed and fresh.
