Description

Technical Field

[0001] The present application relates to the technical field of breast pumps, and in particular to a breast pump. Background Art

[0002] A breast pump is a device used to extract breast milk accumulated in the mammary glands. It is usually used when the baby cannot directly suck breast milk or when it is inconvenient for the mother to breastfeed directly.

[0003] Existing breast pumps have complex internal structures and numerous components. For example, the elastic diaphragm used to generate negative pressure suction is separately connected to the pump body, resulting in additional costs during production, processing, and installation. This separation between the diaphragm and the pump body can also cause milk to be drawn into the pump through the gap between the diaphragm and the pump body during use, potentially damaging the device. The proximity of the diaphragm to the milk flow channel or outlet in existing technologies can also lead to milk seeping into the diaphragm. Utility Model Content

[0004] The present application provides a breast pump to at least solve the technical problems in the related art that the internal structure of the breast pump is complex and milk may be sucked into the air pump.

[0005] In order to achieve the above-mentioned purpose, the present application provides a milk extractor, including a milk receiving bowl, a trumpet cover arranged at the bowl mouth of the milk receiving bowl, and an elastic diaphragm, the trumpet cover extending toward the interior of the milk receiving bowl with a circulation portion, the end of the circulation portion is formed with a three-way end, the three-way end includes a first port, a second port and a third port, the first port is connected to the circulation portion, the second port cooperates with the elastic diaphragm, the third port is connected to a milk receiving container and is provided with a check valve, the elastic diaphragm is integrally arranged with the milk receiving bowl, and a vacuum chamber is correspondingly formed on the elastic diaphragm, the vacuum chamber can be connected and cooperated with an external air pump, and the check valve is integrally arranged with the milk receiving bowl.

[0007] In some embodiments, a through hole communicating with the outside is provided on a side of the milk receiving bowl corresponding to the vacuum chamber of the elastic diaphragm, and the elastic diaphragm is covered on the through hole.

[0008] In some embodiments, the diameter of the through hole is smaller than or equal to that of the elastic diaphragm.

[0009] In some of these embodiments, the elastic diaphragm bulges towards the second port, and a cover body extending towards the elastic diaphragm is provided at the second port. The cover body matches the shape of the elastic diaphragm and covers the elastic diaphragm.

[0010] In some of these embodiments, the check valve is a flexible opening and closing piece fixedly connected to the inner side wall of the milk collection bowl.

[0011] In some of these embodiments, one end of the opening and closing piece is connected to the inner side wall of the milk collection bowl through a fixing part, and the other end extends towards the third port and can block the third port.

[0012] In some of these embodiments, the fixing part protrudes relative to the inner side wall of the milk collection bowl, and a limiting part that can abut against the upper end of the fixing part is provided at the three-way end.

[0031] This application provides a breast milk extractor, which includes a milk receiving bowl, a bell cover arranged at the mouth of the milk receiving bowl, and an elastic diaphragm. The bell cover extends towards the inside of the milk receiving bowl to form a circulation part, and a three-way end is formed at the end of the circulation part. The three-way end includes a first port, a second port, and a third port. The first port is communicated with the circulation part, the second port is cooperated with the elastic diaphragm, the third port is communicated with a milk receiving container and is provided with a check valve. The elastic diaphragm is integrally arranged with the milk receiving bowl, and a vacuum pumping cavity is correspondingly formed in the elastic diaphragm. The vacuum pumping cavity can be communicated and cooperated with an external air pump. The check valve is integrally arranged with the milk receiving bowl.

[0032] As shown in the embodiment Figures 1 to 5 A breast milk extractor includes a milk receiving bowl 1 and a bell cover 2 that covers and wraps the mouth of the milk receiving bowl 1. The bell cover 2 extends towards the inside of the milk receiving bowl 1 to form a tubular circulation part 2.1, and the breast milk sucked out flows into the inside of the milk receiving bowl 1 through the circulation part 2.1.

[0033] Furthermore, the milk receiving bowl 1 is provided with a through hole 1.1 connecting the inside and outside of the milk receiving bowl. Through hole 1.1 is covered by an elastic diaphragm 4 located within and integrally formed with the milk receiving bowl 1. Specifically, the elastic diaphragm 4 is integrally formed with the milk receiving bowl 1 using a secondary injection molding process. A three-way port 5 is formed integrally with the end of the circulation portion 2.1 located within the milk receiving bowl 1. The three-way port 5 includes a first port 5.1, a second port 5.2, and a third port 5.2. The first port communicates with the circulation portion 2.1, the third port 5.2 communicates with the milk receiving container and is provided with a check valve, and the second port 5.1 is tightly fitted with the elastic diaphragm 4.

[0034] Specifically, the elastic membrane 4 protrudes toward the second port 5.1 within the milk receiving bowl 1, dividing the milk receiving bowl 1 into two independent spaces. The side of the milk receiving bowl 1 where the elastic membrane 4 protrudes toward the second port 5.1 forms the aforementioned milk receiving container, while the side of the elastic membrane 4 facing away from the second port 5.1 forms a vacuum chamber. This vacuum chamber can cooperate with an externally connected air pump to achieve negative pressure suction at the second port.

[0035] Specifically, the elastic diaphragm 4 can tightly cover the second port 5.1, thereby ensuring the sealing of the second port 5.1. The second port 5.1 is provided with a cover 5.3 extending and spreading toward the elastic diaphragm 4 along the circumferential direction. The cover 5.3 matches the shape of the elastic diaphragm 4 and is covered on the elastic diaphragm 4.

[0036] Furthermore, the opening directions of the second port 5.1 and the third port 5.2 are away from each other, and the elastic diaphragm 4 and the check valve matched therewith are respectively located on both sides of the three-way end 5 body.

[0037] Specifically, the through hole 1.1 and the elastic diaphragm 4 are provided at the upper end of the milk receiving bowl 1. The second port 5.1, which cooperates with the elastic diaphragm 4, opens toward the upper end of the milk receiving bowl 1. Accordingly, the third port 5.2, which communicates with the milk receiving bowl 1 and is used for discharging milk, opens toward the lower end of the milk receiving bowl 1. This ensures that during normal use, milk flowing through the circulation portion 2.1 and out of the third port 5.2 does not contact the elastic diaphragm 4, preventing milk from seeping into the vacuum chamber.

[0038] Furthermore, in order to achieve a better installation and air suction effect, the diameter of the through hole 1.1 is smaller than or equal to the elastic diaphragm 4. In this embodiment, the diameter of the through hole 1.1 is equal to the elastic diaphragm 4.

[0039] Further, the check valve is a flexible opening and closing piece 3 fixedly arranged on the inner side wall of the milk receiving bowl 1. The opening and closing piece 3 is integrally formed with the milk receiving bowl 1 and extends towards the third port 5.2. Under normal conditions, the third port 5.2 is in a closed state, and when subjected to an external force, the third port 5.2 is opened. When milk flows through, the opening and closing piece 3 is pushed open to allow the milk to flow out, and then due to the flexible material of the opening and closing piece 3, it automatically resets to close the third port 5.2.

[0040] Specifically, one end of the opening and closing piece 3 is connected to the inner side wall of the milk receiving bowl 1 through a fixing part 3.1, and the other end extends towards the third port 5.2 and can block the third port 5.2. The fixing part 3.1 protrudes relative to the inner side wall of the milk receiving bowl 1, and the three-way end 5 is provided with a limiting part 5.4 that can abut against the upper end of the fixing part 3.1 to achieve auxiliary positioning of the three-way end 5 and even the horn cover 2.

[0041] Specifically, the opening and closing piece 3 and the milk receiving bowl 1 are integrally formed by a secondary injection molding process.

[0042] Further, for the above-mentioned integral setting of the opening and closing piece 3 and the milk receiving bowl 1, the elastic diaphragm 4 and the milk receiving bowl 1, etc., in addition to the secondary injection molding method, ultrasonic welding, pasting and other processes can also be used.

[0043] Further, the necessary main body of this application is only composed of two components, namely the milk receiving bowl 1 and the horn cover 2 that cooperates with the milk receiving bowl 1. Other necessary structures such as the elastic diaphragm 4, the opening and closing piece 3, the three-way end 5, etc. are all integrally and integratedly arranged on the above-mentioned components.

[0044] During use, start the externally connected air pump. The air pump evacuates the vacuum chamber formed between the elastic diaphragms 4. Due to the flexible design of the elastic diaphragms 4, it is more convenient to contract and rebound under the action of the air pump. Under the action of the air pump's suction, the elastic diaphragms 4 elastically deform in the direction opposite to their convex direction, and then generate a negative pressure at the second port 5.1 of the three-way end 5 that closely cooperates with them. This negative pressure is transmitted through the flow-through part 2.1 to the chest that closely fits the horn cover 2 to suck out breast milk. The sucked breast milk flows through the flow-through part 2.1 to the third port 5.2 of the three-way end 5, and then flows into the milk receiving bowl 1. The check valve at the third port 5.2 can effectively prevent the breast milk from flowing back. The integration of the elastic diaphragm 4 and the milk receiving bowl 1 can effectively prevent breast milk from being sucked into the air pump through the gaps.

[0045] Those skilled in the art should understand that the technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as the combinations of these technical features do not conflict, they should all be considered to be within the scope described in this specification.

[0046] The above-described embodiments merely represent several implementation manners of the present application. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several modifications and improvements can still be made, and these all fall within the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
