A neckband fan that supplies cool air to the user's shoulders, neck, and head to deeply feel the cool sensation.

Portable fans are widely used to cool off in the hot summer. Conventional portable fans have a handle made of a stick type, so they must be used while holding by hand. Therefore, since the user always has to hold the portable fan with one hand, there is a very inconvenient problem when using both hands as one hand is restricted.

Due to these problems, recently, a neckband fan 100 as shown in FIG. 1 is popularly sold so that both hands can be used. The neckband fan 100 is configured in a ring shape with one side open so that the neck can be accommodated inside and used while being placed on the shoulder, and the inlet 101 and the first and second outlets 102 ( 103) is provided, and a driving fan 104 for sucking in and discharging air and a battery 105 for supplying power to the driving fan 104 are mounted in the inner storage compartment.

Therefore, when the switch is operated in the ON state, the motor is driven by the power of the battery 105 to rotate the driving fan 104, and accordingly, the outside air is pumped into the inner storage compartment through the inlet 101 and then the first and second It is discharged through the outlets 102 and 103 to cool the user's shoulders, neck and head.

However, since the conventional neckband fan 100 of FIG. 1 does not have a cooling means, it simply blows fresh outdoor air away from the user around the user's shoulder, neck, and head, so in hot weather where the outdoor air temperature itself is high There is a problem that you can hardly feel the cool sensation. In particular, when humid air is continuously supplied around the shoulders, neck, and head in hot weather with high humidity, there is a problem in that the unpleasant feeling reaches the extreme, causing an adverse effect.

As for the patent document of the conventional neckband fan, Utility Model Registration No. 20-0487688 "necklace type fan" was announced on October 22, 2018. The claims of this registered patent are "in a necklace-type fan mounted on the user's neck,

Hereinafter, the configuration of the neckband fan according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in the drawing, the neckband fan 1 according to the present invention is used in a state where the user's neck is accommodated inside and placed on the shoulder, and the entrance 21 communicates with the internal storage compartment 24 on both sides of the open front periphery ) is formed, the first outlet 22 is formed on both inner sides of the open front periphery and the second outlet 23 is formed on both sides in the longitudinal direction of the housing 2;

It is mounted around the entrances 21 on both sides and rotates by power supply to forcefully feed the outside air to the inner storage room 24 through the inlet 21 and blow it to the outside through the first and second outlets 22 and 23. driving fan (3);

a battery 4 electrically connected to the motor of each driving fan 3 to supply power to the motor; and

An ice pack (5) installed in the internal storage compartments (24) on both sides to be able to enter and exit and cools the air supplied through the inlet (21) and then discharged through the first and second outlets (22) and (23). .

Since the housing 2 is used in a form wrapped around the neck and seated on the shoulder, the overall shape is composed of a ring shape with one side open, as shown in FIGS. 3 and 7 . In the housing 2, an elastic member 25 is inserted into the rear portion so that both sides of the front side can be opened and closed based on the opened portion. Therefore, both sides of the front side can freely open, close, and twist by this elastic member 25. In addition, a flexible member 25a of a thin plate having plasticity is embedded inside the elastic member 25, so that both front sides are kept open, folded, or twisted.

The housing 2 is provided with internal storage compartments 24 to store necessary parts on both sides of the front side, and the outside air supplied to the inlet 21 formed outside the front periphery of the inner storage compartment 24 is an ice pack ( After being cooled by 5), the first outlet 22 formed inside the front periphery and the second outlet 23 provided at the upper part in the longitudinal direction according to the guidance of the guide member 26 are divided and discharged.

Here, when the guide member 26 is manufactured in various shapes, the amount of cold air discharged through the first and second outlets 22 and 23 can be selectively adjusted. That is, depending on the shape of the guide member 26, more cold air can be discharged to one of the first and second outlets 22 and 23, and the same amount of air can be discharged to the first and second outlets 22 and 23. It might even let the cold air out.

When the present invention is worn on the shoulder while accommodating the user's neck, since the first outlet 22 is located at the lower part of the user's face, the cool air discharged through the first outlet 22 rises by convection and moves to the face. cool down overall. In addition, since the second outlet 23 is located at the upper part in the longitudinal direction, it cools both sides of the neck and head coolly as it is discharged along the neck.

The housing 2 has a structure in which a plurality of ribs 27 protrude to fix the driving fan 3, battery 4, and ice pack 5 to the internal storage compartment 24, and these ribs ( 27) are known technologies, so a detailed description thereof will be omitted.

A power button (B) for turning ON/OFF the power of the battery (4) and a USB terminal (C) for charging the battery (4) are mounted on the housing (2) of the present invention.

On the other hand, the housing 2 of the present invention accommodates the ice pack 5 at the lower part where the user's shoulder touches, as shown in FIGS. The metal cool block 6 may be integrally assembled. The cool block 6 may use a metal material having excellent thermal conductivity, for example, an inexpensive aluminum material having good thermal conductivity, and other metal materials capable of achieving the object of the present invention may be used.

The cool block 6 may have various shapes, and those shown in the drawings are only a part of them. In the cool block 6 of FIGS. 5 to 6 , a battery storage part 6a protrudes from the outside. In this way, when the battery compartment 6a is formed outside the cool block 6, the upper part of the ice pack 5 is freed from obstacles, so that cold air flows smoothly. A hole 6c may pass through the upper wall 6b of the cool block 6 so that cool air can pass smoothly.

Meanwhile, when a non-rechargeable battery 4 is used in the battery compartment 6a, a stopper M is detachably assembled at the entrance so that the used battery 4 can be replaced. Since the detachable structure of the stopper is a well-known technique, further description thereof will be omitted.

The cool block 6 of FIGS. 8 to 9 shows that there is no battery accommodating part 6a on the outer surface. In this case, since the battery compartment 6a is located above the cool block 6, the outer surface of the housing 2 does not protrude, so that the exterior of the housing 2 can be smoothed.

Since the cool block 6 has a considerable length as shown in FIG. 4 and accommodates the ice pack 5 therein, the entire cool block 6 is cooled by the ice pack 5 and spreads cold air widely. Therefore, when the neckband fan 1 of the present invention is worn on the user's shoulder, the cool block 6 located at the lower part of the housing 2 is placed on the clothes around the shoulder, so that the shoulder and lower neck located around it are very cool. In addition, since the cool air diffused by the cool block 6 rises upward and is discharged through the second outlet 23, the upper neck and the head can feel cool at the same time.

Therefore, compared to the conventional neckband fan, in the present invention, since the cool block 6 cooled by the ice pack 5 spreads the cold air widely around the neck, the user wearing it can You can feel the coolness deeply and enjoy the cool feeling.

The driving fan 3 rotates the motor by power supply and the wheel mounted on the rotational shaft of the motor rotates to force the outside air through the inlet 21 to the internal storage room 24, and then to the first and second outlets ( 22) Discharge to (23).

The battery 4 is mounted in a state accommodated in the battery compartment 6a, and is electrically connected to the motor of the driving fan 3 to supply power to the motor when the power button B is operated so that the motor rotates. do it The battery compartment 6a for accommodating the battery 4 is installed in a place where the inner storage compartment 24 of the housing 2 can be installed. Depending on the location, it will be possible to install it in various places.

In addition, the battery 4 can be used both rechargeable and non-rechargeable. The rechargeable type can be charged with external power using the USB terminal (C), and the non-rechargeable type can be simply replaced with a new one by opening and closing the cap (M) when it is discharged due to long-term use.

The ice pack 5 is a very important element in that the neckband fan 1 of the present invention is equipped with a cooling means to provide cool air to the user.

Since this ice pack 5 is a kind of refrigerant, it can be manufactured in various sizes and shapes, and can be manufactured by selectively applying various materials.

In one embodiment, the ice pack 5 may be manufactured as an eco-friendly refrigerant using starch, as described in Patent Registration No. 10-1656508. For example, after putting 94 to 99% by weight of carbohydrates including starch and 1 to 6% by weight of a water-soluble polymer mixture including polyvinyl alcohol (PVA) in a container, the container is indirectly heated through water to cool the container in boiling water. While stirring the liquid for 30 to 100 minutes, the refrigerant is completed, and when using the refrigerant, it can be dissolved in water at a rate of 400 g of water to 100 g of the refrigerant and frozen.

The ice pack 5 of the present invention may be manufactured using starch as described above, or, as is known, a super absorbent polymer (SAP) in which water is absorbed may be used.

The ice pack 5 is mounted inside the cool block 6 through a passage (not shown) of the housing 2 in a frozen state during use, and the passage is closed by a cover 29 . The ice pack (5) is exposed to room temperature and is gradually thawed as time passes and the cold air weakens, so if the cold air is weak or absent, the user can open the cover (29) and replace it with a new frozen ice pack (5) to use for a long time. can

The shape of the ice pack 5 can be manufactured in various ways according to the shape of the cool block 6 in which it is accommodated. 5 and 8 show that the cross section is semicircular, and FIGS. 6 and 9 show that the cross section is circular. As such, it goes without saying that the ice pack 5 can be configured in various forms according to the shape of the receiving portion of the cool block 6 .

In the present invention configured as described above, since the ice pack 5 installed in the inner storage compartment 24 can be supplied to the user's shoulders, neck, and head, it is possible to deeply feel the cool feeling even in hot weather, especially the ice pack ( 5), the cool block 6 made of metal with good thermal conductivity diffuses the cool air received from the ice pack 5 around the worn area to cool a wider area, that is, the shoulder, neck, and head, thereby increasing the cooling efficiency. It is an invention with inventive step because it can be easily replaced with a new frozen ice pack 5 when the ice pack 5 melts and the cooling effect is lost, so it is convenient to use.
