Abstract
The utility model provides an anti-overflow wearable breast pump which comprises a feeding bottle, a front cover and a negative pressure chamber, the front cover and the negative pressure chamber are arranged on the feeding bottle, a connecting chamber is arranged between the front cover and the negative pressure chamber, and the connecting chamber is arranged above a bottle opening of the feeding bottle; a buffer chamber is arranged between the feeding bottle and the connecting chamber, and the buffer chamber is respectively communicated with the feeding bottle and the connecting chamber. When a user wears the breast pump to move, the liquid level in a feeding bottle shakes and overflows from the bottle opening or the exhaust hole, and the buffer chamber can collect the overflowing milk and enable the milk to flow back, so that overflow is prevented. Under the normal condition, the bottle opening or the exhaust hole of the feeding bottle faces upwards, when a user inclines the upper body or bends down and the like, the feeding bottle inclines accordingly, if the milk in the feeding bottle is much at the moment, the milk flows out of the bottle opening or the exhaust hole, and the buffering chamber can collect the milk flowing out and prevent the milk from overflowing out of the feeding bottle.
