A kind of source bottle for solaode diffusing procedure, including multiple inside are placed with the bottle of diffusion source solution,
The upper end of each bottle is equipped with air inlet and gas outlet, and an air inlet pipe is inserted into the bottle by the air inlet
Bottom, an escape pipe is connected with the bottle upper end by the gas outlet, and the escape pipe and the air inlet pipe
Nozzle diameter it is consistent；The escape pipe of each bottle is adjacent the air inlet pipe of bottle and passes through telescopic joint, described sleeve pipe
Sealing fixation is carried out by O-ring seal with the connecting portion of the escape pipe and the air inlet pipe.
Preferably, the bottle is integrally formed with the air inlet pipe, the escape pipe.
Preferably, the nozzle diameter of described sleeve pipe is straight with the mouth of pipe of the air inlet pipe more than or equal to the escape pipe
Footpath.
Preferably, the nozzle diameter of described sleeve pipe is less than the nozzle diameter of the escape pipe and the air inlet pipe.
