FINE BUBBLE LIQUID GENERATOR
To provide a fine bubble liquid generator capable of securing a water quantity of a sufficient quantity by preventing water pressure reduction in supply water, while securing required fine bubble density.SOLUTION: A water communication pipe 2 connected to a water service pipe 12 has a swelling part 4 diametrically expanded in a part. The swelling part 4 is provided with a support member 6 having an inner ring part 6a for holding a nozzle 5 on its inner periphery, an outer ring part 6b fixed to the swelling part 4 and a plurality of width parts 6c for connecting the inner ring part 6a and the outer ring part 6b. The nozzle 5 comprises a plurality of water intake holes 8 inclined to the axis of a supply water pipe 2 of water service in the central axis on an inlet side water intake plate 7, and service water obliquely discharged from the respective water intake holes 8 is jetted to a second water communication passage 8b by increasing a speed while turning in a spiral shape on an inner wall of a first water communication passage 8a. A fine bubble liquid of including an infinite number of ultra-fine cavitation bubbles is increased by sudden pressure reduction at this time. The fine bubble liquid is discharged to the downstream side by merging with the service water of passing between the width parts 6c opened in the support part 6 without passing through the nozzle 5.SELECTED DRAWING: Figure 2
【課題】必要な微細気泡濃度を確保しつつ、供給水の水圧低減を防止して十分な量の水量を確保可能な微細気泡液生成器を提供する。【解決手段】水道配管１２に接続される通水管２は一部に拡径された膨出部４を有する。膨出部４には、ノズル５をその内周で保持する内環部６ａと、膨出部４に固定される外環部６ｂと、内環部６ａと外環部６ｂとを繋ぐ複数の輻部６ｃとを備える支持部材６が設けられている。ノズル５は、入口側の取水プレート７に中心軸が水道の給水管２の軸に対し傾斜している取水孔８を複数具備して、各取水孔８から斜めに放出される水道水は、第１通水路８ａの内壁を螺旋状に旋回しながら速度を上げて第２通水路８ｂへ噴出される。このときの急激な圧力低下により無数の極微細なキャビテーション気泡を含む微細気泡液が増成される。そして、微細気泡液は、ノズル５を通過せずに支持部６に開口された輻部６ｃの間を通過する水道水と合流して下流へ放出される。【選択図】図２
