Problems solved by technology

[0003] At the initial moment of deflation of the breast pump assembly, because the airbag and the airbag cover are closely attached at this time, the entrance of the gas into the airbag is almost equal to the size of the pumping hole, which greatly reduces the speed of gas filling into the airbag; In addition, the airbag is attached to the airbag cover, and the airbag cover has a certain adsorption effect on the airbag, which causes the initial stage of deflation, and the rebound of the airbag is very slow, which reduces the efficiency of the entire milk pumping

Embodiment Construction

[0024] refer to Figure 1 to Figure 6 According to an embodiment of the present invention, a breast pump with a quick-rebound air bag includes a three-way breast collector 1 and a breast pump assembly. The sucking end of the three-way breast collector 1 is connected with a trumpet-shaped breast shield 3, and the inner surface of the breast shield 3 is laid with a massage latex pad 8, and the massage latex pad 8 is turned outward along the edge of the breast shield 3 to form a curl; The milk-collecting end of the three-way milk collector 1 is connected with a milk-collecting bottle 2; meanwhile, the milk-collecting end of the three-way milk collector 1 is also provided with a one-way valve 7 that can prevent the milk from flowing backwards, and the one-way valve 7 can only be used in one way. Through the emulsion, the emulsion backflow in the feeding bottle 2 can be avoided. An air pressure chamber 4 communicating with the inside of the three-way milk collector 1 is provided a...

Abstract

The invention discloses a breast pump with an airbag capable of quick rebounding. The breast pump comprises a tee milk collector and a milk suction pump assembly, an air pressure chamber communicatedwith the interior of the tee milk collector is formed in the upper portion of an airflow end of the tee milk collector, and an opening is formed in the upper portion of the air pressure chamber; the airbag is arranged in the air pressure chamber, an airbag cover is arranged above the opening, and an air pumping hole communicated with the milk suction pump assembly is formed in the airbag cover; multiple annular grooves which are communicated with one another are formed in the bottom of the airbag cover, and one annular groove is communicated with the air pumping hole. Since the annular grooveswhich are communicated with one another are formed in the bottom of the airbag cover, air enters the annular grooves through the air pumping hole, can flow back along the annular grooves and is quickly dispersed, the effect is achieved that more air simultaneously takes effect on the inner surface of the airbag fitting the bottom of the airbag cover, the airbag can be quickly separated from the bottom of the airbag cover and rebound, and the milk suction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of maternity and infant appliances, in particular to a breast pump with a quick rebound air bag. Background technique [0002] The breast pump changes the pressure inside the breast pump through the change of the air bag. The breast pump assembly pumps air, the air bag shrinks, and the inside of the breast pump turns to negative pressure, and the milk flows out; the breast pump assembly deflates, the air bag rebounds, and the suction The inside of the milk container becomes normal pressure, so that the continuous circulation can realize the absorption of milk. [0003] At the initial moment of deflation of the breast pump assembly, because the airbag and the airbag cover are closely attached at this time, the entrance of the gas into the airbag is almost equal to the size of the pumping hole, which greatly reduces the speed of gas filling into the airbag; In addition, the airbag is attached to the airbag co...
