FIG. 4 shows a circuit diagram, in which the motor 6 is a DC motor, the battery 7 is a so-called C-cell battery, and the switch 4 is a normally open contact a contact.

Next, a method of using the portable electric fan 1 according to the first embodiment will be described.

The size of the portable electric fan 1 is a small 3
The length is about a few centimeters shorter than a portable folding umbrella of step folding,
The thickness is slightly smaller and compact, so that it can be easily carried in a handbag or commuter bag at all times, and can be taken out when the sweat is hot and used as a handheld fan.

In the portable electric fan 1 shown in FIG. 1, the guard plate 8a is opened in a substantially conical shape at the right half of the fan 3 at the tip of the fan 3 and the blades 3a of the fan 3 are rotated to expand. The left half of the figure shows the stored state of the blade in which the operating cylinder 5 moves upward in the figure to close the guard plate 8a in a substantially cylindrical shape and the blade 3a of the fan 3 is bent in a substantially square shape. Is shown.

First, at the time of carrying, the portable electric fan 1 is shown in FIG.
When the operation cylinder 5 is moved in the direction of the arrow as shown in FIG.
The guard plate 8a is fitted into the cylindrical portion 5a by pressing the outer surface of the cylindrical member 5a while sliding from the root portion to the tip end, and thus the six guard plates 8a are closed in a substantially cylindrical shape, and the blade 3a is The blade 3a is protected by being bent and stored inside the guard plate 8a, and the stopper 3e below the guard plate 8a is separated from the switch 4, so that the fan 3 does not rotate at all.

Next, when the portable fan 1 is used, as shown in FIG. 3, when the operation tube 5 is moved in the direction of the arrow, the expansion ring 9a connected to the operation tube 5 is closed on the inner surface of the operation tube 5. The inner surfaces of the six guard plates 8a are pushed to open these guard plates 8a in a radially inverted conical shape, and a stopper 8e below one guard plate 8a pushes the switch 4 to activate the motor circuit, and the fan 3 is turned on. The blades 3a rotate to be in an expanded state by centrifugal force. Then, the user holds the main body 2 in his hand and sends wind to the face and neck. Here, the operating means 9 is constituted by the expanding ring 9a and the stopper 8e.

Further, when a string is passed through a string hole 8d provided in two opposed guard plates 8a and the string is hung on the neck, the wind can be received while both hands are free.

As described above, only the operation of the operation cylinder 5 with one touch operation is convenient for carrying and can be used immediately as a fan, and can also be used for drying nail polish.

In order to operate the switch 4, the switch may be directly pushed or slid by an operation protrusion or recess provided on the operation cylinder 5.

Next, a second embodiment of the present invention will be described with reference to FIGS.

The portable electric fan 11 according to the second embodiment is characterized in that the operation tube is extended to the tip side by the length of the blade, and a long protection tube 15 which also functions as a blade storage means. is there.

Reference numeral 11 denotes a portable electric fan according to the present invention. The portable electric fan 11 includes a main body 12 having a motor 6 and a battery 7 built therein, and a bent and unfolded fitting fitted to a rotating shaft 6a of the motor 6. It comprises a fan 3 composed of possible blades, a switch 4 for operating a motor circuit, and a slidable operating cylinder 15 fitted to the main body 12.

The main body 12 is formed from three points of a motor case 12a, a battery case 12b, and a battery cover 12c from the front end side. The motor 6 is built in the motor case 12a and the motor case 12a The switch 4 is provided on the inner surface, and an operation piece 4a of the switch 4 projects from a switch hole 12d opened on a side surface of the motor case 12a.
Flanges 12e and 12f are formed at both ends of the outer periphery of 2a. The battery case 12b has a substantially cylindrical shape, and its front end is fitted to the rear end of the motor case 12a, and the battery lid 12c is detachably attached to the rear end of the battery case 12b. .

The fan 3 is made of a soft synthetic resin.
It has a plurality of blades 3a, 2 to 4, which can be bent in a substantially right angle direction by applying a force, and which is in an expanded state by centrifugal force when rotated. .

The protection cylinder 15 has a long cylindrical shape, and the operating cylinder 5 in the first embodiment is extended to the tip side by the length of the blade, and the blade 3a is provided on the inner surface thereof to the front side. The protective cylinder 1 serves also as a function of a blade storing means for storing in a bent state.
Reference numeral 5 denotes a projection which is a slidable fitting on the outer periphery of the motor case 12a and is a half-moon-shaped operating means for pushing the operating piece 4a of the switch 4 behind the inner peripheral surface of the protective tube 15. A ring 15a is provided, and the raised ring 15a is restricted by the flanges 12e and 12f, so that the protective cylinder 15 can move in the thrust direction by a predetermined length between the flanges 12e and 12f.

FIG. 8 shows a circuit configuration diagram, in which a motor 6 is a DC motor, and a battery 7 is a series of two so-called AA batteries.
The switch 4 is constituted by a normally open contact a contact.

Next, the portable electric fan 11 of the second embodiment
How to use is explained.

The size of the portable fan 11 is several centimeters shorter than a small three-fold portable folding umbrella and about half the size of a small portable folding umbrella. It is easy to carry around and can be taken out when hot and sweaty and used as a handheld fan.

In the portion of the fan 3 at the end of the portable electric fan 11 shown in FIG. 5, the right half shows the state where the blades 3a of the fan 3 are expanded, and the left half shows the protection cylinder 15 as shown by a two-dot chain line. This indicates that the blade 3a moves upward and is bent in a substantially right angle.

At the time of carrying, the portable fan 11 moves the protection tube 15 to the left side of the drawing as shown in FIG. 6 and the blade 3a is bent to be stored and protected on the inner surface of the protection tube 15, and the operating piece 4a of the switch 4 Since the switch 4 which protrudes from the switch hole 12d on the side surface of the motor case 12a and is an a-contact makes the motor circuit inoperative, the fan 3 does not rotate at all.

In use, as shown in FIG. 7, the portable fan 11 moves the protection cylinder 15 to the right side in the figure, and as shown in FIG. 5, the projection ring 15a serving as the operating means inside the protection cylinder 15 is switched. The motor circuit is actuated by pressing the operating piece 4a of 4 and the fan 3 is rotated to be in an expanded state by centrifugal force, and the main unit 12 is held in hand to send air to the face.

As described above, the blade 3a can be easily stored and carried by simply moving the protection cylinder 15, and a cool wind can be obtained by operating the blade 3a immediately.

[0034]

As described above, according to the present invention, the blade can be easily carried by folding the blade by one-touch moving operation, and when taken out and used as a hand-held fan, it is possible to comfortably go out in summer. .
