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 a breast pump, which relates to the technical field of breast pumps and comprises a three-way pipe. The three-way pipe is provided with a liquid inlet end, a negative pressure end and a liquid outlet end which are internally communicated with one another; the liquid inlet end corresponds to a breast suction cover of the breast pump; the negative pressure end corresponds to a negative pressure device of the breast pump; a vertically downward liquid outlet is formed in the liquid outlet end; the liquid outlet is provided with a valve plate at the outer side port of the three-way pipe; the valve plate is attached to and blocks the liquid outlet; a fixed end is arranged on one side of the valve plate, and the fixed end of the valve plate is fixedly arranged; an opening and closing end is arranged on the other side of the valve plate and can be opened towards the outer side of the liquid outlet. According to the three-way structure for the breast pump, the half-opening and half-closing valve plate is arranged at the liquid outlet to replace a duckbill valve in the prior art, the one-way liquid outlet function is achieved, meanwhile, the length of a valve mouth is reduced, and the situation that liquid cannot be discharged due to the fact that the valve mouth stretches into a feeding bottle excessively is avoided.
