The fixed cover 5 covers the negative pressure opening 21 and forms a negative pressure chamber together with the negative pressure driving diaphragm 3. One end of the manual driving member 4 extends toward the interior of the milk storage container 2 to form a connecting portion 41. The connecting portion 41 passes through the fixed cover 5 and is connected to the negative pressure driving diaphragm 3.

[0045] In this embodiment, the fixed cover 5 is connected to the negative pressure opening 21 defined in the milk storage container 2 and, together with the negative pressure driving diaphragm 3, forms a negative pressure chamber. The negative pressure driving diaphragm 3 can reciprocate within the negative pressure chamber. The fixed cover 5 is plugged into the negative pressure opening 21. One end of the manual driving member 4 extends to form a connecting portion 41, which passes through the fixed cover 5 and connects to the negative pressure driving diaphragm 3. The fixed cover 5 also serves to guide the movement of the connecting portion 41. The fixed cover 5 is made of a hard plastic material, which is durable and lightweight. It can also be made of a lightweight metal, such as an aluminum alloy or a titanium alloy.

[0046] In the embodiment of the present utility model, the negative pressure driven diaphragm 3 is recessed into the milk storage container 2, and a diaphragm movement space is formed between the negative pressure driven diaphragm 3 and the fixed cover 5. Intermittent pressing of the manual driving member 4 drives the negative pressure driven diaphragm 3 to reciprocate, thereby generating intermittent negative pressure in the milk storage container 2.

[0047] In this embodiment, the negative pressure driven diaphragm 3 is a bowl-shaped structure that is recessed into the milk storage cavity of the milk storage container 2. The fixed cover 5 and the negative pressure driven diaphragm 3 enclose a larger diaphragm movement space. When the manual driving part 4 is intermittently pressed, the negative pressure driven diaphragm 3 can reciprocate in the larger diaphragm movement space, thereby applying a larger intermittent negative pressure to the milk storage cavity, thereby improving the milk suction efficiency of this manual breast pump 100.

[0048] In the embodiment of the present invention, the fixed cover 5 extends in a direction away from the other end of the manual driving member 4 to form an extension portion 51 , and the extension portion 51 extends along the outer peripheral wall of the milk storage container 2 .

[0051] In this embodiment, a groove extending along the circumference of the fixed cover 5 is formed on the surface facing away from the negative pressure driving diaphragm 3, and a connecting portion 41 is provided at one end of the manual driving member 4. The connecting portion 41 passes through the negative pressure cavity from the bottom of the groove and is connected to the negative pressure driving diaphragm 3. The middle part of the manual driving member 4 abuts against the top of the groove wall of the groove, and can rotate relative to this as a fulcrum, making the rotation of the manual driving member 4 more stable and controllable.

[0052] In the embodiment of the present utility model, the negative pressure driven diaphragm 3 is provided with an escape hole 31, and a latching protrusion 42 is formed on the end of the connecting portion 41 away from the milk storage container 2. The latching protrusion 42 is fixed to the edge of the escape hole 31 facing the milk storage chamber, and the other end of the connecting portion 41 passes through the fixing cover 5 and is connected to one end of the manual driving member 4.

[0053] In this embodiment, the connection between the connecting portion 41 and the negative pressure drive diaphragm 3 is achieved by providing a relief hole 31 in the negative pressure drive diaphragm 3, and forming a latching protrusion 42 on the end of the connecting portion 41 away from the milk storage container 2. The latching protrusion 42 passes through the relief hole 31 and latches onto the side of the relief hole 31 facing the milk storage chamber. When the connecting portion 41 moves outward, it drives the negative pressure drive diaphragm 3 outward, thereby applying negative pressure to the milk storage chamber and achieving a milk extraction effect. It is understood that in other embodiments, the connection between the connecting portion 41 and the negative pressure drive diaphragm 3 may also be achieved by providing a latching protrusion 42 and a latching groove on the negative pressure drive diaphragm 3 and the connecting member, respectively, for a removable connection.

[0054] In the embodiment of the present invention, a convex rib 32 is formed on the edge of the avoidance hole 31 away from the milk storage cavity, and the convex rib 32 is surrounded by the outer peripheral wall of the connecting portion 41 .
