This creation is the water tank and water tank baffle of a kind of respiration therapeutic device to be helped for sleep with what,Wherein the bottom surface of water tank baffle is equipped with a first pipe and a second pipe,The length of the short what second pipe of the length of first pipe; This creation by water tank baffle is arranged in water tank,Therefore the gas into water tank is made to need above and below in what water tank and turn to circuitous flow,Flow path and residence time through lengthening gas,So that gas can be merged sufficiently with aqueous vapor,And then reach the effect of increasing gas humidity; In addition,Water tank baffle can more be such that gas constantly hits,It shunts,And change gas flow rate,Air impingement different in flow rate is allowed to collaborate etc. again,To produce a variety of different sound frequencies,And by making in water tank sound frequency caused by gas everywhere different,And it can reach the effect of avoiding resonance and then noise abatement.本創作係一種用於幫助睡眠的呼吸治療器的水箱及水箱隔板,其中水箱隔板的底面上設有一第一管道及一第二管道,第一管道的長度短於第二管道的長度;本創作藉由在水箱內設置水箱隔板,因此使進入水箱的氣體需於水箱內上下及轉向迂迴流動,透過加長氣體的流動路徑及滯留時間,以使氣體可充分與水氣融合,進而達到增加氣體濕度之功效;此外,水箱隔板更可使氣體不斷撞擊、分流,且改變氣體流速,再讓不同流速的氣體撞擊合流等等,以產生出多種不同的聲音頻率,並且藉由使水箱內各處氣體所造成的聲音頻率不同,而可達到避免共振進而減噪的功效。
