This creation is a kind of hydraulic pressure bubbler,It is mainly that there is what one tubular body of air inlet to install a water flow speedup component,The water flow speedup component protrudes into the inside of second component mainly with the extension pipe portion of its first component one end,Make to extend the air inlet gap that a connecting pipe body air inlet is formed between the second water channel in pipe portion and second component,First component what, which extends, forms a small-bore speedup water channel in pipe portion,Input the water of pressurization from the water intake end of tube body,By contracting in the water flow speedup component of inside, small-bore speedup water channel generates water flow acceleration,And mixed by the extraneous air of air inlet sucking with water send out again simultaneously,Thereby,The function of oxygenation in water-bed water flow speedup and water is provided to flowing water culture equipment.本創作係一種水壓氣泡器，其主要係於一具有進氣孔的管體內部裝設一水流增速組件，該水流增速組件主要以其第一構件一端的延伸管部伸入第二構件的內部，使延伸管部與第二構件內之第二水道間形成一連通管體進氣孔的進氣間隙，第一構件於延伸管部中形成一小口徑的增速水道，使加壓的水自管體的入水端輸入，通過內部之水流增速組件中縮小口徑的增速水道產生水流加速作用，並同時通過進氣孔吸入外界的空氣與水混合再送出，藉此，對活水養殖設備提供水底水流增速與水中增氧的功用。
