Title:
MICROBUBBLE GENERATOR
Document Type and Number:
WIPO Patent Application WO/2020/024330
Kind Code:
A1
Abstract:
A microbubble generator, comprising a water inlet pipe (10), and a housing (20) in threaded connection with the water inlet pipe (10), a gap being reserved and a first air inlet channel (51) being formed between threads; a pressure boost pipe (30) disposed in the housing (20), a gap being reserved and a second air inlet channel (52) in communication with the first air inlet channel (51) being formed between the pressure boost pipe (30) and the housing (20); and a bubble generation pipe (40) disposed in the housing (20), wherein a gap is reserved and a third air inlet channel (53) is formed between an end face of the bubble generation pipe (40) close to the pressure boost pipe (30) and a corresponding end face of the pressure boost pipe (30). The pressure boost pipe (30) comprises a first water inlet (31) and a first water outlet (32). The inner diameter of the first water outlet (32) is less than the inner diameter of the first water inlet (31), such that water pressure at the first water outlet (32) is greater than water pressure at the first water inlet (31), and thus the flow velocity at the first water outlet (32) is increased, and air passing through the three air inlet channels (51, 52, 53) is sucked into the bubble generation pipe (40) and is mixed with water to generate large bubbles. The housing (20) is also internally provided with a cutter (60), and the large bubbles are cut into microbubbles by the cutter (60).
