Abstract (en)

Disclosed is a concealed flow regulator, which comprises a housing portion (100) and a diversion device (200), the housing portion is disposed with a mutation cavity (110) and a suction passage (120), the diversion device (200) is used to divide the water flowing, the divided water enters the mutation cavity (110) and negative pressure generates, air at the outer side is sucked in under the action of the negative pressure through the suction passage (120) and the air and the water are mixed to generate bubble water; the external revolution surface of the housing portion (100) is disposed with external thread (150), the housing portion (100) is threaded to the water supplying opening (700) via the external thread (150); the suction passage (120) has an internal port (121) faced to the mutation cavity (110) and an external port (122) at the external revolution surface, an air flowing clearance is formed between the housing portion (100) and the inner wall of the water supplying opening (700), the air flowing clearance is connected to the external port, so that air can enter the mutation cavity (110) through the air flowing clearance, the external port and the internal port.
