Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a wearable breast pump. Background Art

[0002] A breast pump is an important device to help lactating women express milk. For mothers who have difficulty breastfeeding, a breast pump is a very convenient and useful tool. Currently, breast pumps on the market are mainly divided into two categories: manual and electric. With the advancement of technology, electric breast pumps are becoming more and more widely used and have gradually become the mainstream of the breast pump industry.

[0003] Wearable breast pumps are a typical design among breast pumps at present, and the outer layer of the breast cup part thereof is composed of a shell and a breast shield assembly sealed at the front end of the shell. In the related art, since the three-way assembly is pre-installed on the breast shield assembly and then installed as a whole into the breast cup shell, the applicant found in a long-term follow-up investigation that the three-way assembly is not constrained by the unlimited structure on the side close to the shell, which leads to the three-way assembly and the breast shield assembly being easily misaligned when being installed on the shell as a whole, and the three-way assembly is not supported on the side close to the shell, and the breast pump is easily vibrated under the action of high-frequency negative pressure when it is running, causing the associated connection part to be dislocated. Utility Model Content

[0004] The utility model aims to solve one of the technical problems in the related art to a certain extent at least. In view of this, a wearable breast pump is provided, including a breast pump cup. The breast pump cup includes a shell having an inner cavity and a front end opening. A breast shield assembly is arranged at the front end opening of the shell. A three-way assembly is arranged on one side of the breast shield assembly close to the shell. A limiting slot is arranged on one of the shell and the three-way assembly, and a card block that can be matched and inserted into the limiting slot to limit the movement of the three-way assembly is arranged on the other.

[0005] According to an example of the utility model, a limit block extending toward the inner cavity of the shell is provided on the inner wall of the shell, the limit slot is provided on the limit block, and the block is provided on the outer wall of the three-way assembly.

[0006] According to an example of the utility model, the three-way assembly includes a cylindrical body with one end closed, the open end of the cylindrical body is provided with a first interface portion connected to the breast shield assembly, the upper end of the cylindrical body is provided with a second interface portion for installing a negative pressure membrane, and the lower end of the cylindrical body is provided with a third interface portion for communicating with a one-way valve; the clamping block is respectively connected to the outer walls of the cylindrical body and the second interface portion and is integrally formed with the cylindrical body and the second interface portion, and the limit block extends into the gap between the cylindrical body and the second interface portion.

[0007] According to an example of the utility model, the negative pressure membrane is bowl-shaped and inserted into the second interface portion, the outer edge of the negative pressure membrane is provided with an outwardly folded curled edge, the curled edge is provided with a membrane clamping groove, and the clamping block is synchronously clamped into the limit clamping groove and the membrane clamping groove.

[0008] According to an example of the utility model, the breast shield assembly includes a trumpet-shaped breast shield for covering the breast, and a suction cup cover which is arranged in the middle of the breast shield and is integrally formed with the breast shield; the suction cup cover expands in the same direction as the breast shield and a thinning groove is left between the outer wall of the suction cup cover and the inner wall of the breast shield.

[0009] According to an example of the present invention, at least one gripping portion is provided on the peripheral side of the breast shield, and the gripping portion protrudes outward away from the middle portion of the breast shield.

[0010] According to an example of the present invention, the outer edge of the opening of the breast shield is provided with a flexible curling portion folded outwards.

[0011] According to an example of the utility model, it also includes a control host, in which a negative pressure air pump is arranged, and the negative pressure air pump is connected to the second interface part of the milk suction cup through a negative pressure pipeline.

[0012] According to an example of the present invention, the breast shield assembly and the three-way assembly are an integrally formed structure.

[0013] Compared with the prior art, the technical solution of the utility model has the following advantages: 1. By iteratively optimizing the internal structure design of the wearable breast pump, mutually matching limiting structures are respectively arranged on the shell of the breast pump cup and the three-way assembly, for example, a limiting slot is arranged on the shell and a card block is arranged on the three-way assembly at the same time, or vice versa, so that when the three-way assembly together with the breast shield assembly is installed on the breast pump cup shell, the matching limiting effect of the card block and the limiting slot can ensure the precise alignment assembly of the breast pump cup, and the three-way assembly together with the breast shield assembly will not be skewed after being installed, and on the other hand, the three-way assembly close to the shell side is stably supported, and the breast pump is not easy to vibrate during operation, causing the loosening and dislocation of related components.

[0014] 2. By optimizing the structure of the breast shield assembly and making a thinning groove at the connection between the one-piece suction cup cover and the breast shield, the thickness of the breast shield assembly corresponding to the nipple area can be reduced while ensuring the structural strength of the breast shield assembly. When the breast pump continuously uses negative pressure to suck milk, the pressure on the local skin can be reduced to avoid suction marks.

[0015] 3. Expand the functional structure of the breast shield assembly. First, add a gripper design to facilitate opening the breast cup. Second, design an outward-turned flexible curled edge at the opening edge of the breast shield, which is flexible and close to the skin without hurting the chest, thus improving the user experience.
