As shown in fig. 1 to 3, a breastshield 100 according to one embodiment of the present application is illustrated, including a breastshield main body 10, a breastshield connector 20, and an elastic member 30. The bra main body 10 has an annular structure, the bra connector 20 has a cylindrical structure, and the bra connector 20 is connected with the bra main body 10.

Alternatively, the bra attachment 20 may be integrally formed with the bra body 10 or may be removably attached. For example, in the present embodiment, the brassiere connector 20 and the brassiere body 10 are integrally formed, so that not only is the brassiere 100 provided with better sealing performance, but also the number of parts can be reduced, and the complexity of installing and using the brassiere 100 can be reduced.

Alternatively, in one embodiment, the bra body 10 is made of a silicone material. The silica gel material is soft in texture and good in elasticity, and can be well deformed in a telescopic way under the action of negative pressure suction force, so that the silica gel material can be automatically attached to the surface of the breast according to different breast sizes of a user without using the silica gel material, and the milk sucking effect is ensured.

Referring to fig. 4, a first accommodating chamber 11 is formed inside the bra main body 10, and a second accommodating chamber 21 communicating with the first accommodating chamber 11 is formed inside the bra joint 20; the elastic member 30 is mounted on the bra body 10, and the elastic member 30 can adaptively deform in a telescopic manner following the telescopic deformation of the bra body 10.

The implementation of the embodiment of the utility model has the following beneficial effects:

when the breast shield 100 of the above-mentioned scheme is used, the bra main body 10 is used for being assembled and matched with the breast of a user, namely, the bra main body 10 is covered outside the breast of the user, the breast is positioned in the first accommodating cavity 11, meanwhile, the bra connector 20 is used for being connected with a pipeline and communicated with a host machine, so that negative pressure suction can be generated in the breast shield 100 along with the suction air of the host machine during milk suction, and the nipple of the user stretches into the second accommodating cavity 21 at the moment; because the elastic piece 30 is arranged on the side wall of the first accommodating cavity 11, when the bra main body 10 is deformed in a telescopic way due to negative pressure suction, the elastic piece 30 can synchronously follow the bra main body 10 to carry out self-adaptive telescopic deformation, so that breasts and nipples with different sizes can be self-adaptive, the elastic piece 30 can be well clung to the front end of the breasts to avoid gaps, the negative pressure suction effect is ensured, the milk sucking effect is ensured, the phenomenon that milk overflows due to leakage of breast milk from the gaps is prevented, the better service performance of the breast pump is ensured, and meanwhile, the experience of a user is also ensured and promoted.

Alternatively, the elastic member 30 is a spring, and the material may be metal, plastic, or the like.

It will be appreciated that the second receiving chamber 21, in addition to being adapted to receive the nipple, also serves as a milk suction channel, i.e. milk, after having flowed out of the nipple under suction, flows further along the second receiving chamber 21 and finally into the breast cup for temporary storage.

In one embodiment, the bra body 10 gradually increases in inner diameter from a first end to a second end, the first end of the bra body 10 being connected to the bra connector 20. That is, the bra body 10 is formed in a cone-shaped structure in this embodiment. Alternatively, as an alternative to the foregoing embodiment, the outer shape of the bra main body 10 may be not a tapered cylindrical structure, but only the first receiving chamber 11 may be formed as a tapered cylindrical chamber, and the small diameter end of the bra main body 10 may be connected to the bra joint 20. So configured, the tapered sidewall formed by the first receiving chamber 11 can better fit and conform to the breasts of the user, and can accommodate breasts of different sizes, enhancing the application range of the breastshield 100.

To better accommodate the assembled connection with the bra body 10 and the bra connector 20, in one embodiment, the elastic member 30 is formed in a cylindrical configuration such that the configuration of the elastic member 30 is consistent with the bra body 10 and the bra connector 20, and one end of the elastic member 30 is integrally formed with the bra body 10.

For example, when the bra main body 10 is injection molded by silica gel, the elastic member 30 is put into the mold together, the elastic member 30 can be integrally formed with the latex main body made of silica gel, so that higher connection strength is ensured, and the number of parts of the bra 100 can be reduced besides the synchronicity of the expansion deformation of the bra main body 10 and the elastic member 30.

Of course, in other embodiments, the elastic member 30 may be detachably assembled with the bra main body 10, for example, the elastic member 30 and the bra main body 10 may be detachably assembled by one of a snap connection, an adhesive connection, a screw connection, etc., so as to facilitate the separate removal of the elastic member 30 for cleaning.

Alternatively, in order to obtain excellent elastic deformability of the elastic member 30, the elastic member 30 is preferably made of one or at least two materials of copper, rubber, and the like.

On the basis of any of the above embodiments, the elastic member 30 has an outer sidewall having the same slope as that of the sidewall of the bra body 10. Since the slope of the outer sidewall is the same as the slope of the sidewall of the bra body 10, the bra body can automatically generate self-adaptive deformation according to the shape of the front end of the breast during the sucking process to be clung to the front end of the breast, thereby avoiding the generation of gaps and obtaining more milk sucking effect.

Referring to fig. 4, further, the elastic member 30 has an outer sidewall, which is flush with the sidewall of the bra body 10. If the outer sidewall protrudes from the sidewall of the bra main body 10 (i.e., the outer sidewall is higher than the sidewall of the first accommodating cavity 11), a step-shaped protrusion is formed, and when the bra 100 covers the breast of the user, the step-shaped protrusion will scrape the breast to cause discomfort and affect wearing comfort; if the outer sidewall is recessed in the sidewall of the first accommodating cavity 11 (i.e., the outer sidewall is lower than the sidewall of the first accommodating cavity 11), the elastic member 30 will cause the gap to generate and affect the suction effect even if the elastic member follows the bra body 10 to generate adaptive expansion and deformation, and the gap from the front end of the breast is too large to be effectively and tightly attached to the front end of the breast.

On the basis of any of the above embodiments, the other end of the elastic member 30 extends to the junction of the bra main body 10 and the bra joint 20. The joint of the bra main body 10 and the bra connector 20 just corresponds to the joint of the nipple and the breast, the other end of the elastic piece 30 can be accurately and effectively tightly attached to the front end of the breast, and meanwhile, the nipple and the first accommodating cavity 11 are effectively sealed and separated, so that the attaching effect of the elastic piece 30 and the front end of the breast is ensured, and the problem of milk overflow is prevented.

Referring to fig. 4, optionally, an arc-shaped bending portion 31 is formed at the other end of the elastic member 30, and the arc-shaped bending portion 31 is bent toward the bra connector 20. During the milk sucking operation, the expansion and deformation of the breast shield 100 along with the suction force can cause the relative movement between the breast shield 100 and the nipple, at this time, the contact part of the formed arc-shaped bending part 31 and the nipple is a smooth convex arc-shaped surface, and the contact area of the convex arc-shaped surface and the nipple is smaller, so that the friction damage of the elastic piece 30 to the nipple can be reduced.

Referring to fig. 4, further, the curved bending portion 31 is matched with the side wall of the bra connector 20 at intervals to form a milk overflow preventing groove 40. Specifically, the cross section of the arc-shaped bending portion 31 is a hook-shaped structure, and the elastic member 30 is a cylindrical three-dimensional structure, so that the formed anti-overflow milk groove 40 is also an annular groove, and when breast milk sucked from the nipple during the milk sucking process cannot enter the milk cup in time through the passage to flow back, the breast milk can directly flow into the anti-overflow milk groove 40 for temporary storage and is blocked from flowing into the first accommodating cavity 11, so that the problem of milk overflow is caused.

It is easy to understand that when the anti-overflow channel 40 is filled with milk, the milk still flows along the milk sucking channel to the milk cup, so that the waste of the milk is avoided.

On the basis of any of the above embodiments, the peripheral edge of the end of the breast shield body remote from the breast shield fitting is also integrally connected to a support rim 50. The supporting edge is specifically an annular plate-shaped structure with a certain width, when the breast-sucking bra 100 is covered on the breast of a user, the supporting edge 50 is convenient for the user to press the breast part by hands, and the contact area between the supporting edge 50 and the breast part is large, so that the supporting stability and the sealing performance of the installation of the breast-sucking bra 100 can be effectively improved.

Further, the side of the supporting edge facing the bra joint is provided with a connecting buckle edge structure in a protruding way near the outer periphery edge. The connecting buckle edge structure specifically comprises a positioning flange 60 and a fixing buckle edge 70 which are concentrically arranged inside and outside, and a certain width interval is arranged between the positioning flange 60 and the fixing buckle edge 70. During installation, the interfaces of the breast cups are inserted from the intervals and buckled to the inner sides of the fixing buckling edges 70, and the interface butt joint of the positioning flange 60 to the breast cups prevents the interface butt joint from being easily separated from the fixing buckling edges 70, so that the assembly and the fixation of the breast shield 100 and the breast cups can be completed.

In summary, the present application further proposes a breast pump, which includes a milk sucking assembly as described in any of the above embodiments, a main unit and an air tube, wherein the main unit is in communication with the milk sucking assembly through the air tube.

As one embodiment, the milk sucking assembly comprises a milk sucking cover 100, a three-way piece and a milk collecting container, wherein the milk sucking cover 100 is in a horn-shaped annular structure, the milk sucking cover 100 is used for being covered on a breast of a user, the milk collecting container is used for storing sucked breast milk, and the three-way piece is respectively communicated with the milk collecting container, the milk sucking cover 100 and a negative pressure source (such as an air pump). The three-way piece can be integrated on the breast shield 100 or the milk collecting container, and can be arranged separately from the breast shield 100 and the milk collecting container. The breastshield 100 may be attached to a milk collection container or may be connected to a tee via tubing.

When in use, the breast shield 100 is covered outside the breast of a user, the three-way piece is communicated with the air pump of the main machine, and the air pump provides negative pressure suction for the breast shield 100 through the three-way piece, so that breast milk is sucked from the nipple and discharged to the milk collecting container.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples illustrate only a few embodiments of the utility model, which are described in detail and are not to be construed as limiting the scope of the utility model. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the utility model, which are all within the scope of the utility model. Accordingly, the scope of protection of the present utility model is to be determined by the appended claims.
