Technical Field

[0001] This utility model relates to the field of electric breast pump technology, and in particular to a suction component for an electric breast pump. Background Technology

[0002] With the fast pace of modern life and the popularization of the concept of breastfeeding, electric breast pumps have become an important auxiliary tool for many breastfeeding mothers.

[0003] Existing electric breast pumps are prone to leakage when pumping milk, which not only wastes milk but also causes inconvenience to users. Traditional breast pumps may cause breast discomfort, and existing breast pumps rarely have a breast massage function, which cannot effectively relieve breast discomfort during the pumping process and is not conducive to milk secretion. Utility Model Content

[0004] The main objective of this invention is to provide a suction component for an electric breast pump, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a suction component for an electric breast pump, comprising a connecting shell, a duckbill valve provided at the lower part of the connecting shell, a suction assembly provided at the upper part of the connecting shell, a breast shield provided on one side of the connecting shell, a vibration mechanism provided on the outer periphery of the breast shield, and the breast shield, the suction assembly and the duckbill valve being interconnected.

[0006] The vibration mechanism includes a fixed shell, a hollow cup motor, and an eccentric block. The outer periphery of the fixed shell is fixedly connected to the outer wall of the breast pump, the outer periphery of the hollow cup motor is disposed inside the fixed shell, and the middle part of the eccentric block is fixedly connected to the output end of the hollow cup motor.

[0007] Preferably, the breast shield has massage protrusions on the inner wall near the connecting shell, and the massage protrusions are arranged in a ring.

One end of the connecting tube is fixedly connected to the middle of the upper side of the sealing cap. The lower side of the sealing cap is disposed on the outer periphery of the upper part of the connecting shell. The inner sidewall of the connecting ring is fixedly connected to the outer periphery of the upper part of the rubber membrane. The lower outer periphery of the connecting ring is disposed on the upper part of the connecting shell. The connecting ring is disposed between the connecting shell and the sealing cap.

[0011] Preferably, the connecting tube is connected to the breast pump operating unit via a flexible tube.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] The hollow cup motor drives the eccentric block to rotate, generating vibrations that are transmitted to the breast shield through the fixed shell. The massage protrusions massage the breast, promoting milk secretion. A leak-proof ring is located near the opening of the breast shield to prevent leaked milk. At the same time, a soft sealing gasket made of medical-grade silicone is provided around the edge of the opening of the breast shield. This gasket has good elasticity and sealing properties, and can closely fit different breast shapes to effectively prevent milk leakage. Attached Figure Description

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] like Figure 1-4As shown, a suction component for an electric breast pump includes a connecting shell 1, a duckbill valve 2 at the lower part of the connecting shell 1, a suction assembly 3 at the upper part of the connecting shell 1, a breast shield 4 on one side of the connecting shell 1, and a vibration mechanism 7 on the outer periphery of the breast shield 4. The breast shield 4, the suction assembly 3, and the duckbill valve 2 are interconnected. In summary, a hollow cup motor 702 is driven, causing the eccentric block 703 to rotate, thereby generating vibration. This vibration is transmitted to the breast shield 4 through the fixed shell 701. The massage protrusions 6 massage the breast, promoting milk secretion. A leak-proof ring 5 is located near the opening of the breast shield 4 to prevent leaked milk. Simultaneously, a soft sealing gasket is provided around the edge of the opening of the breast shield 4. This sealing gasket is made of medical-grade silicone, which has good elasticity and sealing properties, and can closely conform to breasts of different shapes, effectively preventing milk leakage.

[0021] The vibration mechanism 7 includes a fixed shell 701, a hollow cup motor 702, and an eccentric block 703. The outer periphery of the fixed shell 701 is fixedly connected to the outer wall of the breast shield 4. The outer periphery of the hollow cup motor 702 is disposed inside the fixed shell 701. The middle part of the eccentric block 703 is fixedly connected to the output end of the hollow cup motor 702, driving the hollow cup motor 702 to rotate the eccentric block 703, thereby generating vibration. This vibration is transmitted to the breast shield 4 through the fixed shell 701, thereby massaging the breast and promoting milk secretion.

[0022] The breast pump 4 has massage protrusions 6 on the inner wall near the connecting shell 1. The massage protrusions 6 are arranged in a ring shape. During the breast pumping process, the massage protrusions 6 can massage the breast and promote milk secretion.

[0023] A leak-proof ring 5 is provided on the inner side of the breast shield 4 away from the connecting shell 1. The leak-proof ring 5 is located near the opening end of the breast shield 4 and can block the leaked milk. At the same time, a soft sealing gasket is provided around the edge of the opening end of the breast shield 4. The sealing gasket is made of medical-grade silicone, which has good elasticity and sealing performance, and can closely fit the breast of different shapes to effectively prevent milk leakage.

[0024] A handle 8 is provided on one side of the duckbill valve 2. By pulling the handle 8, the duckbill valve 2 can be easily pulled off from the middle of the connecting shell 1, making it convenient to replace or clean the duckbill valve 2.

[0025] The suction assembly 3 includes a sealing cap 301, a connecting ring 302, a rubber diaphragm 303, and a connecting tube 304. One end of the connecting tube 304 is fixedly connected to the upper middle part of the sealing cap 301. The lower inner side of the sealing cap 301 is disposed on the upper outer periphery of the connecting shell 1. The inner wall of the connecting ring 302 is fixedly connected to the upper outer periphery of the rubber diaphragm 303. The lower outer periphery of the connecting ring 302 is disposed on the upper part of the connecting shell 1. The connecting ring 302 is disposed between the connecting shell 1 and the sealing cap 301. The rubber diaphragm 303 is deformed by the external breast pump operating unit, thereby changing the pressure inside the connecting shell 1, and thus performing milk suction.

[0026] The connecting tube 304 is connected to the breast pump operating unit via a flexible tube. The breast pump operating unit is existing technology and adopts the operating unit of a breast pump disclosed in Chinese Patent Publication No. CN104661694A.

[0027] Working principle:

[0028] The hollow cup motor 702 drives the eccentric block 703 to rotate, thereby generating vibration. This vibration is transmitted to the breast shield 4 through the fixed shell 701. The massage protrusions 6 massage the breast, promoting milk secretion. The leak-proof ring 5 is located near the opening of the breast shield 4 to block leaked milk. At the same time, a soft sealing gasket is provided around the edge of the opening of the breast shield 4. This sealing gasket is made of medical-grade silicone, which has good elasticity and sealing performance, and can closely fit the breast of different shapes to effectively prevent milk leakage.
