Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and in particular to a horn cover for a breast pump. Background Technology

[0002] A breast pump is a convenient tool that helps breastfeeding mothers express milk. It works by utilizing vacuum suction; a motor or manual operation drives a piston or diaphragm to reciprocate, generating negative pressure that forces milk out of the milk ducts and into a storage bottle through a three-way valve.

[0003] Chinese utility model patent application No. 202122018772.6 discloses a breast pump main unit kit and the breast pump itself. This patent uses a horn-shaped suction cup to press against the breast, creating a sealed environment inside, and then uses negative pressure to draw out milk. While this patent allows for the replacement of different horn cup shapes to fit various users' breast shapes, changing the horn cups is cumbersome, and the fixed shape of the horn cup cannot effectively correspond to the breast shape of every user, resulting in insufficient sealing and affecting the user experience. Utility Model Content

[0004] To address the aforementioned technical issues, this utility model provides a horn cover for a breast pump. The double-layer cover structure effectively improves the sealing performance of the breast pump when drawing milk, making it convenient to use.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] This utility model provides a horn cover for a breast pump, the horn cover being sealed and connected to the negative pressure inlet end of the breast pump; an annular protrusion is provided at the base of the horn cover opening; the annular protrusion is arranged circumferentially along the inner wall of the horn cover opening; the annular protrusion has a horn-shaped structure and expands and extends towards the inlet direction of the horn cover.

[0007] The present invention provides a horn cover for a breast pump, wherein preferably, the annular protrusion is coaxially arranged with the horn cover.

[0008] The present invention provides a horn cover for a breast pump, wherein preferably, the depth dimension of the annular protrusion facing the liquid inlet direction is not greater than the depth dimension of the horn cover facing the liquid inlet direction.

[0009] The above technical solution has the following advantages or beneficial effects: This utility model provides a horn-shaped cover for a breast pump, relating to the field of maternal and infant product technology. The horn-shaped cover is sealed and connected to the negative pressure inlet of the breast pump; an annular protrusion is provided at the base of the horn-shaped cover opening; the annular protrusion is arranged circumferentially along the inner wall of the horn-shaped cover opening; the annular protrusion has a horn-shaped structure and expands and extends towards the inlet direction of the horn-shaped cover. This utility model provides a horn-shaped cover for a breast pump, which, by setting an annular protrusion to fit closely to the areola, can reduce the area required for sealing, thereby improving the sealing performance. It can better adapt to different breast shapes and improve the user experience. Attached Figure Description

[0013] Figure 1-2 Includes: 1. Speaker cover; 2. Ring-shaped protrusion. Detailed Implementation

[0014] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses and methods consistent with some aspects of this application as detailed in the appended claims.

[0015] Example 1:

[0016] like Figure 1-2 As shown,

[0017] This utility model provides a horn cover for a breast pump. The horn cover 1 is sealed and connected to the negative pressure inlet end of the breast pump. An annular protrusion 2 is provided at the root of the opening of the horn cover 1. The annular protrusion 2 is arranged circumferentially along the inner wall of the opening of the horn cover 1. The annular protrusion 2 has a horn-shaped structure and expands and extends towards the inlet direction of the horn cover 1.

[0018] When the horn cover of the breast pump provided by this utility model needs to be attached to the breast for breast pumping, the horn cover 1 is first pressed onto the breast, with the annular protrusion 2 aligned with the areola. After pressing, a sealed space is formed between the annular protrusion 2 and the areola, and a sealed area is also formed between the breast area around the areola and the horn cover 1. If the annular protrusion 2 detaches from the areola and loses its seal during breast pumping, the sealed area formed between the breast area around the areola and the horn cover 1 can ensure that the breast pump continues to work normally. In addition, since the areola area is relatively small, sealing this area with the annular protrusion 2 makes it easier to adapt to the shape of the areola, eliminating the need to replace the corresponding horn cup.

[0019] The present invention provides a horn cover for a breast pump. By setting an annular protrusion 2, it can form two sealing areas on the breast with the horn cover 1, which can effectively improve the sealing reliability of the breast pump. The annular protrusion 2 can be attached to the areola to better fit breasts of different shapes and improve ease of use.

[0020] To facilitate alignment of the annular protrusion 2 with the areola during use, this invention provides a horn cover for a breast pump. Preferably, the annular protrusion 2 and the horn cover 1 are coaxially arranged. By aligning the annular protrusion 2 with the horn cover 1, the position of the inner annular protrusion 2 can be better determined based on the position of the outer horn cover 1, thus allowing for faster alignment with the areola and improving ease of use.

[0021] To improve the coverage of the breast pump and increase user comfort, this invention provides a breast pump cover. Preferably, the depth of the annular protrusion 2 facing the liquid inlet direction is not greater than the depth of the breast pump cover 1 facing the liquid inlet direction. By setting the depth of the breast pump cover 1 facing the breast direction to be greater than or equal to the depth of the annular protrusion 2, the breast pump cover 1 can cover a larger breast area than the annular protrusion 2. This structural design increases the contact area, improving comfort, and also stabilizes the annular protrusion 2, preventing it from detaching from the areola during pumping and affecting the pumping effect.

[0022] Other embodiments of this application will readily occur to those skilled in the art upon consideration of the specification and practice of the application filed herein. This application is intended to cover any variations, uses, or adaptations of this application that follow the general principles of this application and include common knowledge or customary techniques in the art not claimed herein. The specification and examples are to be considered exemplary only, and the true scope and spirit of this application are indicated by the appended claims.

[0023] It should be understood that this application is not limited to the precise structure described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this application is limited only by the appended claims.
