Abstract

PURPOSE: To enjoy sound of a musical box without requiring consciousness of switching in/out while fanning with a fan to get coolness, eliminate troublesomeness of replacing batteries, and apply the fan as a multi--purpose fan to be used not only in summer but through all the seasons of spring, summer, fall, and winter. CONSTITUTION: As a fan 1 is moved for fanning, an AC voltage is generated in accordance with swing motion of a piezoelectric element 4 disposed in a fan surface, it is rectified by a diode and converted into a DC voltage by a capacitor to start a musical box IC. Comfortable melody sounds from a piezoelectric speaker 6, or an LED is lighted by this. The melody sounds or light is lighted, therefore, only when fanning with the fan.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fan, which is a tool for making a wind with a fan in a summer feature magazine. By not only simply raising the wind to cool the fan, the fan is used to produce various melody songs. It is a fan that can flow and provide mental comfort, and it also relates to a fan that can be used as a toy with no gap between adults and children.

[0002]

2. Description of the Related Art Generally, a fan is designed to generate a breeze to cool off, but recently, not only a tool for cooling off but also an idea commercial product with various functions has been considered. Even if it is a fan that comes out, it is also a manifestation, and it is a multifaceted that there is a function different from the original function of the fan, such as eliminating the discomfort by making a melody sound or giving a toy property with a sense of playfulness. Some fans have been devised.

Although various types of fans that produce melody sounds are considered, mechanically, an assembly of switches, batteries, melody IC circuits, speakers, etc. is arranged on the handle or fan surface of the fan to produce a melody. When you do, you need to intentionally turn on the switch,
Similarly, when erasing the melody, it is necessary to turn off the switch. Further, it is generally known that a battery or the like is also used as a power source and a new battery must be replaced when the battery life is exhausted. For example, JP
0-108004, Actual Open Flat 1-141510, Flat 4-5
4227 etc.

[0004]

However, in spite of the above-mentioned various proposals, the method of uttering the melody, erasing, turning on and off the light must be turned on and off artificially. The condition is that a battery is required for the power source, and there is a problem that the melody sound is not produced and the light is also extinguished if the battery life is exhausted.

The present invention considers a method of artificially turning a switch on and off, and without using a battery, for generating a melody, erasing a light, turning on and off a light, and unconsciously only when a fan is being fanned. The purpose is a fan with a melody and a light.

[0006]

In order to solve the above problems, in the fan of the present invention, a power generator is attached on the fan surface near the handle, and the music box IC circuit is arranged on the fan surface or on the handle. A piezoelectric speaker is arranged above the fan surface.

The power generator of the present invention uses a piezoelectric element known to convert displacement into voltage and converts the amplitude energy generated by fanning a fan into an AC voltage. The device may be used.

Regarding the mounting position of the piezoelectric element, when the fan is fanned, the area around which the warp deformation of the fan surface begins and the longitudinal direction is aligned with the handle axis so that the displacement energy of the piezoelectric element is maximized. It is desirable to set it up.

The music box IC circuit of the present invention is for rectifying an AC voltage with a diode, smoothing it with a capacitor to generate a DC voltage, and supplying the DC voltage to the music box IC for activation.

[0010]

By fanning the fan configured as described above, an AC voltage is generated according to the amplitude movement of the piezoelectric element arranged on the fan surface, and the diode is used for rectification and the capacitor is used for smoothing the DC voltage. The melody sounds more comfortable than the piezoelectric speaker and the LED lights up. Therefore, in the present invention, the melody sounds and the light is emitted only when the fan is being fanned.

【Example】

Example 1 An example of the present invention will be described with reference to FIGS. 1 and 2.
1 and 2 show an embodiment of a fan according to the present invention. FIG. 4 is a power supply circuit diagram of the present invention.

In the figure, 1 is a fan and 2 is a handle. The material of the handle 2 is generally made of bamboo, but may be made of wood or synthetic resin.

Reference numeral 3 denotes a fan surface, which is a structure in which a plurality of bones extending from the handle are spread on both sides of the rake, and paper is applied from both the front surface and the back surface. The fan surface is made of synthetic resin to integrate the fan bone and the fan surface. The latter may be used in this embodiment.

Reference numeral 4 denotes a piezoelectric element, which has a rectangular shape on the fan surface.
The longitudinal direction is aligned with the same direction as the handle axis, and the distance from the handle portion is preferably a position where the displacement energy becomes maximum when a fan on the handle portion side is fanned.

A music box IC circuit 5 is composed of a diode, a condenser, and a music box IC, and a piezoelectric speaker 6 is used for the output of the melody and is arranged at the upper position of the fan surface.

The music box IC circuit of this embodiment is UM66T-19L, which is a three-terminal music box IC, and uses the song title "For Elise". The specifications are as follows. Supply voltage range = 1.3 to 3.3V Supply current = 60 μA Melody start method = Power-on reset

As the piezoelectric element of this embodiment, an LG30X bimorph vibrator manufactured by Mega Cera Co., Ltd. is used, and the specifications are: Size = 60 L × 20 W × 0.6 T Output voltage = 10.99 V when displacement is 1 mm The condition is that one end is fixed and the music box I is fanned with a fan.
Sufficient power to activate C.

Second Embodiment FIG. 3 shows a second embodiment. FIG. 5 is a power supply circuit diagram of the present invention.

Numeral 7 is an LED, which has a plurality of light emitting portions scattered on the fan surface to be exposed, and a fan is used to fan a constant current to emit light. The light emitting part of the LED of No. 7 is arranged according to the pattern of the fan, and if the LED is made to emit light at the time of the evening cool, a romantic atmosphere is created.

[0020]

Since the present invention is configured as described above, it is possible to enjoy the tone of the music box without being aware of the input / output of the switch while cooling with a fan. It can be applied as a versatile fan not only in the summer tradition but also in the seasons of spring, summer, autumn, and winter, especially when it is cool in the evening, and when the fan is fanned in the dim surroundings, a melody sounds and it is faint. It creates a unique atmosphere where fireflies are dancing for a romantic evening with the lights shining.
