Title: 다중 에너지 절약 샤워헤드
Inventor: MOON BONG SOO
IPC: A47K3/28
Filed: 2008-07-11
Abstract: 본 고안은 절수를 통한 에너지 절감 효과 및 음이온의 발생으로 인한 건강에 도움을 주는 효과, 고압의 미세하고 섬세한 물줄기를 이용한 미용효과를 동시에 충족시킬 수 있는 다중 에너지 절약 샤워 헤드(Multi Energy Shower's Head)에 관한 것으로, 일반적으로 사용되는 샤워 장치의 끝부분인 물이 분사되는 샤워기 헤드와 교체 또는 대체가 용이하게 사용할 수 있는 장치이다. 다중 에너지 절약 샤워 헤드는 건강을 위해 음이온(일반적으로 알려져 있는 음이온의 효과:공기정화,인체의 자율신경계 조절 등)을 생성시켜주는 음이온 증폭부, 물의 흐름을 순간적으로 차단 또는 통과 유량을 조절시켜 줄 수 있는 버튼이 부착된 유량 조절부, 작은 관로를 통해 유속과 수압을 증가시키고, 또한 미세한 구멍을 통해 더욱 물의 유속과 수압을 증가시킬 수 있는 정밀 가공 plate를 통해 물을 분출시킴으로써 통과 유량을 줄여주는 샤워기 몸체부로 구성되어 있다. 
     음이온 증폭부는 상부와 하부가 연결되어 중앙에 빈 공간이 형성되며, 연결은 자체 성형된 암수체결 나사형태로 조합되고, 빈 공간에는 세라믹 볼(음이온을 
     발생하는 천연 특수광물을 세라믹화하여 코팅처리)3개가 들어가게 된다.  
     물이 진동하면서 특수 처리된 세라믹 볼과 부딪히고 이 과정에서 음이온 발생량은 극대화되어 음이온으로 인하여 사용자에게 건강상 여러가지 도움이 될 뿐 아니라,피로회복에 도움을 주어 샤워의 효과를 극대화 시킨다. 
     유량 조절부는 샤워기 헤드의 중간에 위치한 것으로, 유량을 조절할 수 있는 버튼 이 유속방향에 수직으로 관을 통과하여 설치되어 있고, 손가락 등을 사용하여 밀거나 또는 당겨서 관로를 밀폐, 개방 또는 일부개방 등의 조절할 수 있도록 되어 있어 사용자가 간편하게 유량 조절 또는 차단을 통한 절수 기능을 발휘할 수 있도록 되어 있다. 
     샤워기 몸체부는 다중 에너지 절약 샤워 헤드의 가장 윗부분에 위치한 것으로, 유체가 음이온 증폭부와 유량 조절부를 거쳐 샤워기 헤드부로 들어오면 내부의 좁아진 측면에 위치한 hole을 통과하여 유속이 빨라지고, 헤드부 끝단에 있는 plate는  앞.뒤면의 hole 크기가 다른 600여 개의 hole로 이루어진 정밀가공 plate이며 물은 이곳을 통과하여 더욱 높은 속도와 압력으로 샤워기 헤드에서 분출하게 된다. 
     본 고안에 따른 다중 에너지 절약장치에 의하면, 기존 일반 샤워 장치에 장착된 샤워기 헤드와 쉽게 교체할 수 있도록 고안되었고, 유량 조절부를 통해 수동으로 절 수 효과를 볼 수 있음과 동시에 샤워기 헤드부에 설치된 정밀 가공 plate를 통해서 자동으로 대략 20% 정도의 절수 효과를 볼 수 있다. 그러나 이러한  절수로 인해 발생할 수 있는 사용자의 물부족 느낌으로 이한 불편함은 없으며, 사용자가 본래 샤워의 행위에 있어 불편함이 없도록 ,충분한 만족감을 주는 동시에 물의 분출량은 줄어들어 절수효과가 발휘되도록 고안된 것이다. 
     또한, 샤워기 헤드부 내부 유속과 수압이 상승하지만 정밀 가공 plate의 hole을 통해 분출되는 물줄기는 사람의 안면으로 느끼는 수압이 높지않아, 위험하거나 통증이 유발되지는 않는 상태가 되어, 오히려 이를 이용한 피부마사지, 모공의 각질 및 분비물 제거, 두피마사지 등의 미용기능에 효과적일 수 있다. 뿐만 아니라 다량의  음이온이 생성되므로 샤워기 헤드의 사용자 건강에도 도움이 되는 장치이다.
