The best mode for carrying out the present invention will be described with reference to FIGS. 1 to 5, but the present invention is not limited to such an embodiment.

Next, an example will be described.
As shown in FIG. 1 (1), in the portable blower device 1 of the present invention, the blower drive unit 2 having the suction port 4 and the blower passage 3 having the blower port 5 are combined with the blower drive unit 2 and the blower passage 3. With a gap t3
It is configured by combining at the 0-P1 position.

As shown in FIG. 2, the blower drive unit 2 supplies power to the drive motor 6 from the drive motor 6, the blower fan 7 fixed to the drive shaft of the drive motor 6, the power supply unit 8, and the power supply unit 8. The power supply unit 8 has an outside suction port 4 for sucking outside air between the blower fan 7 and the power supply unit 8 by arranging and fixing the SW 9 that turns ON / OFF on the housing 2-1. Set the blower fan 7 to be inside. Then, the outside air a sucked from the suction port 4 is blown in the direction x from the blower fan 7 to the coupling position P0-P1 by using a part of the housing 2-1 as a blower path.

Although not shown, the power supply unit 8, the drive motor 6, and the SW9 are connected by a lead wire.
When SW9 is turned on, power is applied from the power supply unit 8 to the drive motor 6, and SW9 is turned off.
When set to, the power to the drive motor 6 is cut off.

As shown in FIGS. 1 and 2, the air passage 3 guides the outside air a blown from the blower fan to the coupling positions P0-P1 with the blower drive unit 2 in the direction y opposite to the blown direction x. It is composed of a flow passage, and an air outlet 5 is set at the end of the air passage 3. Therefore, the air passage 3 is formed up to the air outlet 5 with the coupling position P0-P1 as the inlet.

As shown in FIG. 1, the portable blower device 1 has a housing 2-1 of the blower drive unit 2 at the position of P0-P1.
By connecting and holding a part of the air passage 3 and the inlet of the air passage 3, the gap between the air drive unit 2 and the air passage 3 on the air outlet 5 side is set to t3, and the thickness of the air passage 3 is set to t4. Set.

As shown by the dotted line in FIG. 2, there are various helmet shapes, so it is preferable to make the gap t3 adjustable so as to correspond.

As shown in FIG. 3, the gap t3 is larger than the outer cap thickness t0 of the helmet to be used, for example, and the thickness t4 of the air passage 3 is the gap between the outer cap 12 and the inner cap 13 of the helmet when attached to the helmet. Set so that it is smaller than t1.
For example, if the general-purpose helmet is t0: about 5.0 mm and t1: about 10.0 mm, t3: about 7.0 mm and t4: about 8.0 mm are set.

The outer cap 12 of the helmet has a hat shape in appearance, and the whole is made of small, lightweight, strong metal or plastic, etc., and the inner cap 13 of the helmet is made of a mesh-like cushioning material, and the head 11 Since the structure is such that the impact applied between the helmet and the outer cap 12 of the helmet is alleviated and the air easily circulates, if air is blown between the outer cap 12 and the inner cap 13 of the helmet, it will be in close contact with the inner cap 13. It can circulate and reach the head 11 and cool the head 11 sufficiently.

Therefore, if a gap t3 is provided between the blower drive unit 2 and the blower passage 3 on the blower port 5 side, and the outer cap 12 of the helmet is inserted into this gap t3 as shown in FIG. 3, the portable blower device 1 can be used. It is possible to mount the blower drive unit 2 on the outside of the helmet and the blower passage 3 on the blower port 5 side on the inside of the helmet.

In the power supply unit 8, the power supply unit 8 is placed outside the blower drive unit 2 with the blower fan 7 inside, and the suction port 4 is arranged between them, so that the outside air outside the blower drive unit 2 and the inside of the blower drive unit 2 are arranged. It is possible to reduce the temperature rise of the power supply unit 8 by simultaneously cooling both sides of the power supply unit 8 by sucking the outside air from the suction port 4.
Further, in order to prevent the temperature from rising, if aluminum, copper, iron or an alloy metal having good thermal conductivity is used for the housing portion around the power supply unit 8, the cooling effect can be further enhanced.

In this way, even if a lithium ion battery that generates heat when power is supplied is used for the power supply unit 8, the temperature rise due to this heat generation can be prevented by cooling by inhaling the outside air and the outside air.
By using a lithium ion battery that is smaller and lighter than a dry battery and has a large capacity, the entire portable blower 1 can be made smaller and lighter.

For the power supply unit 8 used in the present invention, for example, a compact and lightweight lithium ion battery having specifications as shown below is used.

In this way, if the belts 14 attached to both ends of the belt holding portion 10 are wound around the helmet outer cap 12 to fix the portable blower 1 to the outside of the helmet and cover the head.
Since the portable blower 1 is stable and does not shift, the outside air sucked from the outside of the helmet by the suction port 4 is inserted between the outer cap 12 and the inner cap 13 from the blower port 5 to the head 11 of the air passage 3. Sufficient air can be blown inside.

Next, the operation will be described with reference to FIGS. 1 and 2.
The portable blower 1 turns on the SW9 of the blower drive unit 2 and drives the motor 6 from the power supply unit 8.
When power is supplied to the drive motor 6, the blower fan 7 mounted on the drive shaft of the drive motor 6 rotates and the outside air a is sucked from the suction port 4, and the sucked outside air a is sent to the blower drive unit via the blower fan 7. The outside air a sent from 2 to the coupling position P0-P1 in the air blowing direction x and sent to the coupling position P0-P1 is blown from the air vent 5 of the air passage 3 to a predetermined location outside via the air passage 3. It is blown by y. By this ventilation, it is possible to cool a predetermined place outside.

In this way, the portable blower 1 sucks the outside air a from the suction port 4 and blows it from the blower port 5 to a predetermined place outside, so that it can be blown to a place where the body wants to be cool while carrying it, or any arbitrary place. It can be easily blown to a place where it needs to be kept cool.

As shown in FIG. 1 (1), the total width of the divided portion of the air outlet 5 is t6 + t7 with respect to the width t5 of the central portion of the air passage 3, and t5> (t6 + t7). By narrowing the width (area) of the air outlet with respect to the width (area) of the air passage in this way, the wind power output from the air outlet 5 can be partially increased. That is, it is possible to feel cooler by dividing the air into a plurality of parts and blowing the air partially and strongly, rather than blowing the air evenly over the whole.

Next, a usage example will be described with reference to FIGS. 3 and 4.
In FIG. 3, the outer cap 12 of the helmet is inserted into the gap t3 of the portable blower device 1 so that the blower drive unit 2 is located on the outside of the helmet and the blower passage 3 is located on the inside, and the blower drive unit 2 is as shown in FIG.

SW9 is turned on, the outside air from the outside of the helmet is sucked into the blower drive unit 2 from the suction port 4, and then the outside air sucked through the air passage 3 is blown into the inside of the helmet from the blower port 5. Cool the head 11.

In this way, since the portable blower 1 can be easily and stably attached to the helmet, it can be sufficiently used for work with intense movement.
Then, the helmet equipped with the portable blower 1 is put on the head 11 and the SW of the blower drive unit 2 is covered.
If 9 is turned on, the outside air outside the helmet is inhaled and most of the inhaled outside air is taken into the head 11
The inside of the head 11 can be sufficiently cooled by blowing air to the head 11.

Next, the flow of the blast will be described with reference to FIG. First, when the outside air a is sucked from the suction port 4, the outside air a sucked from the blower drive unit 2 in the direction of the arrow x is sent toward the blower path 3. In the air passage 3, the sent outside air a is guided to the air outlet 5 via the air passage formed by the air passage 3 and is indicated by an arrow.
It is blown in the y direction.

As shown in FIG. 5, the suction port 4 and the air outlet 5 are separated from each other, and the air intake port 4 is connected to the air intake port 5 from the air outlet 5.
The air blown in the y direction is hardly returned and re-inhaled, and the outside air a can be effectively used for cooling.

The present invention is a compact and lightweight portable blower that can blow air for a long time with low power consumption. Therefore, even if you do not wear it on a helmet, you can blow air to the place where you want to cool your body while carrying it, or you can put it in any place and blow it to the place where you need to cool, so you can not get power. It is promising to be used in mountains, the sea, or as an evacuation site in the event of a disaster, and has an energy-saving and environmentally friendly effect.
