AI Technical Summary
Technical Problem
In existing breast pumps, the duckbill valve has an excessively long nozzle, which prevents milk from flowing out effectively, thus affecting the pump's performance.
Method used
A semi-openable valve plate is used instead of a duckbill valve. One side of the valve plate is fixed and the other side can be opened. Combined with the collar and seat structure, it ensures that the valve plate opens automatically under appropriate pressure to achieve unidirectional liquid discharge.
Benefits of technology
This effectively avoids the problem of insufficient milk flow caused by milk overflowing the valve, thus improving the efficiency of the breast pump.

Abstract
The utility model discloses a three -way structure for breast pump relates to breast pump technical field, it includes three -way pipe, three -way pipe is equipped with the inside mutual communication liquid inlet end, negative pressure end and liquid outlet end, liquid inlet end corresponds to the breast cup of breast pump, negative pressure end corresponds to the negative pressure device of breast pump, and liquid outlet end is equipped with the liquid outlet that is vertically downward, and the valve piece is equipped with in the lateral port of three -way pipe, and the valve piece is sealed in the liquid outlet, and one side of valve piece is equipped with fixed end, and the fixed end of valve piece is fixed setting, and the other side of valve piece is equipped with the open -and -shut end, and the open -and -shut end of valve piece can open to the lateral of liquid outlet. The utility model provides a three -way structure for breast pump through setting half -openable valve piece of liquid outlet replaces the duckbill valve in prior art, realizes the function of one -way liquid outlet while, reduces the valve nozzle length, avoids too deeply into the feeding bottle and leads to unable liquid outlet.
