Description

공기정화 휴대용 선풍기Air Purification Portable Fan
본 발명은 공기정화 휴대용 선풍기에 관한 것으로, 보다 상세하게는 공기를 정화하는 필터가 구비되어 날개의 회전에 의해 외부에서 유입되는 공기를 효과적으로 정화하고 사용자의 신체에 거치가 용이한 공기정화 휴대용 선풍기에 관한 것이다.The present invention relates to an air-purifying portable fan, and more particularly, to an air-purifying portable fan that is provided with a filter for purifying air to effectively purify the air introduced from the outside by rotation of the wing and to be easily mounted on the user's body. About.
일반적으로 선풍기는 날개의 회전에 의해 발생되는 바람을 이용하여 더위를 식히거나 공기를 순환시키는 용도로 사용된다. 이러한 선풍기는 사용자가 모터의 작동을 조작함에 따라 모터와 연결된 날개가 회전하는 구조를 갖는다. In general, an electric fan is used for cooling the heat or circulating air by using wind generated by the rotation of the blades. Such an electric fan has a structure in which the blade connected to the motor rotates as the user manipulates the operation of the motor.
이러한 선풍기 중에서 정해진 장소에서 사용하는 가정용 또는 사무용 선풍기뿐만 아니라 사용자가 휴대할 수 있도록 날개의 크기가 작고 내장된 배터리나 건전지 등을 이용하여 날개를 회전시키는 휴대용 선풍기도 활발히 사용된다.Among these fans, not only a home or office fan used in a predetermined place, but also a portable fan that rotates the wing using a small size of the wing and a built-in battery or battery so that the user can carry it are actively used.
종래 휴대용 선풍기의 형상은 손잡이가 구비되어 사용자가 손잡이를 잡고 원하는 각도로 바람의 방향을 조절하며 사용하는 것이 일반적이다. 그러나 손잡이를 잡은 상태로 휴대용 선풍기의 바람을 쐬는 경우 다른 일을 수행하는데 방해가 되며 휴대용 선풍기를 거치시키는 별도의 거치수단이 필요하다. 또한, 야외에서 이동 또는 작업 중에는 별도의 거치수단이 있더라도 효과적으로 휴대용 선풍기의 바람을 쐬기 어렵다.The shape of a conventional portable fan is generally provided with a handle so that the user holds the handle and adjusts the direction of the wind at a desired angle. However, if you breathe air from a portable fan while holding the handle, it interferes with performing other tasks, and a separate mounting means for mounting the portable fan is required. In addition, while moving or working outdoors, it is difficult to effectively breathe air from the portable fan even if there is a separate mounting means.
한편, 야외에서 휴대용 선풍기를 이용하는 경우 최근 환경오염과 미세먼지의 증가로 오염물질을 그대로 흡입하게 되는 문제점이 있다. 이를 해결하기 위하여 종래의 공기청정기의 구조를 설계변경하여 휴대용 선풍기에 적용할 수 있으나 구조가 복잡해지고 부피가 커져 휴대성이 떨어지는 문제점이 있고 가격도 비싸진다. 또한, 먼지가 제거된 공기를 흡입하기 위하여 방진마스크 등을 별도로 사용할 수 있으나, 장기간 사용 시 입 주위가 습해져서 불쾌감을 느끼기 쉽다.On the other hand, when a portable fan is used outdoors, there is a problem in that pollutants are inhaled as they are due to an increase in environmental pollution and fine dust. In order to solve this problem, the structure of a conventional air purifier can be changed and applied to a portable fan, but the structure is complicated and bulky, so there is a problem in that portability is inferior and the price is also high. In addition, a dust mask or the like can be separately used to inhale the air from which the dust has been removed, but when used for a long time, the mouth area becomes moist, so it is easy to feel discomfort.
대한민국 등록실용신안 제20-0486077호에서는 선풍기에서 나오는 바람에 오염물질을 제거하기 위하여 선풍기용 에어필터가 개시되어 있는데, 선풍기의 전방면 또는 후방면에 안착되는 여과패드와 여과패드를 고정시키는 결합수단을 제시하고 있다. 그러나, 상기와 같은 구성은 휴대용 선풍기에 적용시키기 다소 어렵고, 적용한다 하더라도 상대적으로 바람의 세기가 약한 휴대용 선풍기의 경우 원활하게 바람이 나오지 않는 문제점이 있다.Republic of Korea Utility Model No. 20-0486077 discloses an air filter for a fan to remove pollutants from the wind from the fan. A combination means for fixing the filter pad and the filter pad seated on the front or rear surface of the fan Are presented. However, the above configuration is somewhat difficult to apply to a portable fan, and even if applied, there is a problem in that the wind does not come out smoothly in the case of a portable fan having a relatively weak wind strength.
위와 같은 점을 감안하여 발명된 본 발명의 목적은 휴대용 선풍기에서 나오는 바람을 정화하여 사용자에게 제공할 수 있고 야외에서 이동 시 사용이 편이한 휴대용 선풍기를 제공하는 것이다.An object of the present invention in consideration of the above points is to provide a portable fan that can be provided to a user by purifying the wind from a portable fan and is easy to use when moving outdoors.
또한, 효과적으로 공기를 정화하고 휴대용 선풍기에서 나오는 바람의 방향을 사용자가 선택적으로 집중시킬 수 있는 휴대용 선풍기를 제공하는 것이다.In addition, to provide a portable fan that can effectively purify the air and allow the user to selectively concentrate the direction of the wind from the portable fan.

도 6 및 도 7은 본 발명의 다른 일 실시예에 따른 휴대용 선풍기의 동작 상태를 나타낸 사시도이다.6 and 7 are perspective views showing an operating state of a portable fan according to another embodiment of the present invention.
도 6 및 도 7을 참고하면, 상기 제2 외측커버(220)에 구비된 전면살(230)은 측면홀(231)을 가질 수 있다. 본 발명의 일 실시예에서 상기 제2 외측커버(220)에 구비된 전면살(230)은 반원 형상으로 상기 선풍기의 전방으로 돌출된다. 상기 전방으로 돌출된 전면살(230)에는 상기 반원 형상으로부터 공기가 이동을 가이드하는 측면홀(231)이 형성되고 상기 측면홀(231)을 따라 바람이 상기 선풍기의 테두리 방향으로 나오게 된다. 상기 전면살(230)의 형상은 반원뿐만 아니라 타원형이나 다각 형상을 가질 수 있다.6 and 7, the front flesh 230 provided in the second outer cover 220 may have a side hole 231. In an embodiment of the present invention, the front flesh 230 provided on the second outer cover 220 protrudes toward the front of the fan in a semicircular shape. A side hole 231 for guiding the movement of air from the semicircular shape is formed in the front flesh 230 protruding forward, and the wind comes out along the side hole 231 in the rim direction of the fan. The shape of the front flesh 230 may have an elliptical shape or a polygonal shape as well as a semicircle.
상기 측면홀(231)을 갖는 본 발명의 일 실시예에 대하여 구체적으로 설명하면, 제2 내측커버(210)에 구비된 전면살(230)과 상기 제2 외측커버(220)에 구비된 전면살(230)이 서로 겹쳐진 상태에서 상기 날개(10)의 회전에 따른 바람의 방향은 선풍기의 전방으로 나오게 된다. 상기 제2 외측커버(220)가 일정 범위 회전하는 경우 상기 제2 내측커버(210)에 구비된 전면살(230)과 상기 제2 외측커버(220)에 구비된 전면살(230)이 서로 인접하여 배치되면서 상기 날개(10)의 회전에 따른 바람의 방향이 선풍기의 전방으로 나오는 것을 차단한다. 이 경우 상기 날개(10)의 회전에 따른 바람의 방향은 측면홀(231)을 따라 상기 선풍기의 테두리 방향으로 나오게 된다. 상기 개구홀(250)에는 별도의 마개가 결합되어 바람이 나오는 것을 차단시키는 것이 바람직하다.When describing in detail an embodiment of the present invention having the side holes 231, the front teeth 230 provided in the second inner cover 210 and the front teeth provided in the second outer cover 220 In the state where 230 is overlapped with each other, the direction of the wind according to the rotation of the blade 10 comes out to the front of the fan. When the second outer cover 220 rotates within a certain range, the front teeth 230 provided on the second inner cover 210 and the front teeth 230 provided on the second outer cover 220 are adjacent to each other. While being disposed, the direction of the wind according to the rotation of the blade 10 is blocked from coming out of the front of the fan. In this case, the direction of the wind according to the rotation of the blade 10 comes out along the side hole 231 in the direction of the edge of the fan. It is preferable that a separate stopper is coupled to the opening hole 250 to block wind from coming out.
상기 제2 외측커버(220)에 구비된 전면살(230)은 상기 전면케이스(200)의 중심에서 테두리 방향으로 진행될수록 상기 전면케이스(200)의 전방으로 돌출되도록 경사질 수 있는데, 이 때 상기 측면홀(231)의 내부 단면적은 상기 전면케이스(200)의 중심보다 테두리 방향에서 더 크게 된다. 상기 날개(10)의 회전에 따른 바람은 상기 제2 외측커버(220)에 구비된 전면살(230)의 경사를 따라 상기 전면케이스(200)의 테두리 방향으로 이동된다.The front flesh 230 provided on the second outer cover 220 may be inclined so as to protrude forward of the front case 200 as it progresses from the center of the front case 200 toward the rim. The inner cross-sectional area of the side hole 231 is larger in the rim direction than the center of the front case 200. The wind caused by the rotation of the wing 10 is moved in the direction of the rim of the front case 200 along the slope of the front meat 230 provided on the second outer cover 220.
