BUBBLER CAPABLE OF ENSURING GAS SUCTION EFFECT UNDER LOW PRESSURE

摘要

Disclosed in the present invention is a bubbler capable of ensuring gas suction effect under low pressure comprises a main body (10), a gas-water mixer (20) and a flow splitter (30) both installed in the main body (10). The flow splitter (30) is provided with a plurality of flow splitting holes (31). A gas suction hole (11) is additionally arranged to suck the air from outside of the main body (10) into the main body (10). The bubbler is also provided with a constant open water line (40) and an open-close water line (50). An open-close member (60) is arranged on the open-close water line (50) in order to open the open-close water line (50) when the water flow pressure is greater than a predetermined water pressure and to close it when the water flow pressure is lower than the predetermined water pressure. All the flow splitting holes (31) are divided into at least a first portion and a second portion. The constant open water line (40) and the open-close water line (50) are independently connected with the first portion and the second portion respectively.
