[0031] The present application provides a milk collection device, including a milk receiving bowl, a horn cover arranged at the mouth of the milk receiving bowl, and an elastic diaphragm. The horn cover extends towards the inside of the milk receiving bowl with 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 matched with the elastic diaphragm, and the third port is communicated with a milk receiving container and is provided with a check valve; the elastic diaphragm is integrally connected to the milk receiving bowl, and a vacuum pumping cavity is correspondingly formed in the elastic diaphragm. An air hole for communicating with an air pump and a through hole for communicating with the outside are arranged on the cavity wall of the vacuum pumping cavity, and a detachable rear cover is arranged at the through hole.

[0032] As shown in the embodiments Figures 1 to 5 shown, a milk collection device includes a milk receiving bowl 1 and a horn cover 2 that covers and wraps the mouth of the milk receiving bowl 1. The horn cover 2 and the milk receiving bowl 1 are mutually snap-connected, and a snap 3 for snap-connection is arranged between the horn cover 2 and the milk receiving bowl 1. The horn cover 2 extends towards the inside of the milk receiving bowl 1 with 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 1.4 connecting the inside and outside of the milk receiving bowl. Through hole 1.4 is covered with an elastic diaphragm 4 located inside and integrally provided with the milk receiving bowl 1. Specifically, the elastic diaphragm 4 is formed integrally with the milk receiving bowl 1 using a secondary injection molding process. A rear cover 1.1 is provided on the outside of the milk receiving bowl 1 to cooperate with and seal the through hole 1.4. The rear cover 1.1 is removable from the through hole 1.4. A three-way port 5 is formed integrally with the circulation portion 2.1 at its end located inside the milk receiving bowl 1. The three-way port 5 includes a first port 5, a second port 5.1, 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 back cover 1.1 can be made of flexible material, and a raised connecting portion 1.3 is provided on the outside of the milk receiving bowl 1 and beside the back cover 1.1. The connecting portion 1.3 is connected to the back cover 1.1 to prevent the back cover 1.1 from falling off and being lost after being removed from the through hole 1.4.

[0035] Specifically, the elastic diaphragm 4 protrudes from the inside of the milk receiving bowl 1 toward the second port 5.1, dividing the bowl 1 into two independent spaces. The side of the milk receiving bowl 1 where the elastic diaphragm 4 protrudes toward the second port 5.1 forms the aforementioned milk receiving container. On the side facing away from the second port 5.1, the elastic diaphragm 4 cooperates with the back cover 1.1 and the inner wall of the milk receiving bowl 1 to form a vacuum chamber. An air hole 1.2 is provided on the side of the back cover 1.1, located on the milk receiving bowl 1, for connecting the air pump to the vacuum chamber. Air hole 1.2 is not located on the back cover 1.1, facilitating removal of the back cover 1.1 for cleaning the vacuum chamber without removing the air pipe connected to the air pump.

[0036] Specifically, the elastic diaphragm 4 tightly covers the second port 5.1, thereby ensuring the seal of the second port 5.1. The second port 5.1 is circumferentially provided with a cover 5.3 that extends and spreads toward the elastic diaphragm 4. The cover 5.3 matches the shape of the elastic diaphragm 4 and is positioned over the elastic diaphragm 4. The elastic diaphragm 4 is circumferentially provided with an abutment portion 4.1 that mates with the cover 5.3. The tight fit between the cover 5.3 and the abutment portion 4.1 further strengthens the seal between the second port 5.1 and the elastic diaphragm 4, preventing leakage of liquids or gases.

[0037] Furthermore, a stepped structure is formed between the main body of the elastic diaphragm 4 and the abutting portion 4.1. The main body of the elastic diaphragm 4 protrudes relative to the abutting portion 4.1 toward the second port 5.1 and is accommodated in the cover 5.3.

[0038] Specifically, in order to achieve a better installation and air suction effect, the diameter of the through hole 1.4 is smaller than that of the elastic diaphragm 4.

[0039] Further, a protruding edge 1.5 is provided on the inner wall of the milk receiving bowl 1 at the edge of the vacuum chamber. This edge 1.5 facilitates the stable fixation of the second-injected elastic diaphragm 4 inside the milk receiving bowl 1, and the second-injected elastic diaphragm 4 is wrapped around the edge 1.5.

[0040] Further, the check valve is a flexible opening and closing piece 6 provided at the third port 5.2. The opening and closing piece 6 is at least partially fixed at the third port 5.2, keeping the third port 5.2 closed under normal conditions and opening the third port 5.2 when subjected to an external force. When milk flows through, the opening and closing piece 6 is pushed open to allow the milk to flow out, and then due to the flexible material of the opening and closing piece 6, it automatically resets to close the third port 5.2.

[0041] Further, the necessary main body of this application consists of only two components, namely the milk receiving bowl 1 and the bell cover 2 that cooperates with the milk receiving bowl 1. Other necessary structures such as the elastic diaphragm 4 and the three-way end 5 are integrally and integratedly arranged on the above-mentioned components.

[0042] Further, for the above-mentioned integrated setting of the elastic diaphragm 4 and the milk receiving bowl 1, the opening and closing piece 6 and the third port 5.2, etc., in addition to the second-injection method, processes such as ultrasonic welding and pasting can also be used.

[0043] During use, start the air pump. The air pump evacuates the vacuum chamber formed between the elastic diaphragm 4 and the rear cover 1.1 through the air hole 1.2. Due to the stepped design of the elastic diaphragm 4, it is more convenient to contract and rebound under the action of the air pump. Under the action of the air pump, the elastic diaphragm 4 undergoes elastic deformation in the direction opposite to its protruding direction, thereby generating a negative pressure at the second port 5.1 of the three-way end 5 that closely cooperates with it. This negative pressure is transmitted through the flow portion 2.1 to the chest that closely fits the bell cover 2 to suck out breast milk. The sucked breast milk flows through the flow portion 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 the breast milk from being sucked into the air pump through the gap.

[0044] 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.

[0045] 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 on 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.
