Abstract:
A flow stabilizing container cover. The flow stabilizing container cover comprises a cover body (1) provided with a sealing and blocking piece (2), and comprises a liquid outlet (3) and an air inlet (4) both formed in the sealing and blocking piece (2). The lower end of the sealing and blocking piece (2) is fixedly provided with an air inlet channel (5). The air inlet channel (5) is in communication with the air inlet (4). The tail end of the air inlet channel (5) is provided with a pressure equalizing assembly. The pressure equalizing assembly comprises a cover cap (6), a conical pressure equalizing core (7), and a base (8) that is in sleeved connection with the cover cap (6). The cover cap (6) comprises a bucket-shaped cap top (61) provided with a hole and comprises an upper air inlet tube (62). The bucket-shaped cap top (61) is in communication with the upper air inlet tube (62). A support (82) is disposed on the inner wall of the base (8). The lower end of the base (8) is provided with a lower air inlet tube (81). The conical pressure equalizing core (7) is disposed in a working cavity (9) formed by the base (8) and the cover cap (6). The conical pressure equalizing core (7) matches the bucket-shaped cap top (61). The flow stabilizing container cover has a high reverse throttling accuracy, ensures separation of air feeding and liquid discharging, and enables liquid in the liquid outlet to stably flow out, and avoids splashing.
