[0032] The collection part of the existing manual breast pump usually contacts the milk and needs to be cleaned, while the driving part usually does not contact the milk and does not need to be cleaned. However, the collection part and the driving part of the existing manual breast pump are difficult to disassemble and assemble, making it inconvenient to use.

[0033] The utility model provides a manual breast pump, which aims to realize quick disassembly and assembly between a collecting component and a driving component, thereby improving the use efficiency of the manual breast pump.

[0034] See also Figures 1 to 6 In one embodiment of the present invention, the manual breast pump 100 includes a collection component 10 and a drive component 20. The collection component 10 includes a breast shield 11, a diaphragm 12 and a milk storage container 13. One side of the breast shield 11 is used to fit the breast, and the other side is formed with a milk suction channel. The milk storage container 13 has a milk storage cavity, which is connected to the milk suction channel. The diaphragm 12 is sealed and connected to the breast shield 11 or the milk storage container 13. A surface of the diaphragm 12 facing away from the breast shield 11 or the milk storage container 13 is provided with a first connecting portion 121; the drive component 20 includes a milk collecting component 10, a milk collecting component 10, and a milk collecting component 10. The assembly 20 includes a first shell 21, a second connecting portion 22 and a driving portion 23. The driving portion 23 is mounted on the first shell 21 and is drivingly connected to the second connecting portion 22. When the first shell 21 is detachably connected to the breast shield 11 in a first direction, the second connecting portion 22 is detachably connected to the first connecting portion 121 in a second direction. The driving portion 23 drives the second connecting portion 22 to cause the diaphragm 12 to vibrate back and forth in the second direction, thereby applying negative pressure to the breast shield 11 or the milk storage chamber, wherein the first direction and the second direction are arranged at an angle.

[0035] In this embodiment, the breast shield 11 is designed to conform to the user's breast and has a funnel-shaped or hemispherical shape that conforms to the breast. To enhance the user experience, the breast shield 11 is made of a soft, skin-friendly material, such as silicone or latex, for increased comfort and less likely to cause skin allergies. A milk storage container 13 includes a milk storage cavity, which communicates with a milk extraction passage and is used to collect milk. The cavity can be a milk bowl, milk bag, or milk bottle, and the like, but this is not further defined herein. The diaphragm 12 can be sealedly connected to the breast shield 11, applying negative pressure to the milk extraction passage to draw milk from the breast and flow it into the milk storage container 13 for temporary storage. Alternatively, the diaphragm 12 can be sealedly connected to the milk storage container 13, applying negative pressure to the milk storage cavity to draw milk from the breast and flow it into the milk storage container 13 for temporary storage. The specific placement of the diaphragm 12 is not further defined herein. The first connection portion 121 may be integrally formed with the diaphragm 12 , or may be provided separately from the diaphragm 12 and connected as one through a connection method such as snap-fitting or plug-fitting.

[0036] The first shell 21, first connecting portion 121, and second connecting portion 22 can all be made of a durable, lightweight hard plastic material, or lightweight metal, such as aluminum alloy. The removable connection between the first shell 21 and the breast shield 11 can be achieved by snapping or by using a pin-and-groove mechanism. The first shell 21 and breast shield 11 are removably connected in a first direction, preferably horizontally. During the connection between the first shell 21 and the breast shield 11, the first connecting portion 121 and the second connecting portion 22 are already aligned, eliminating the need for time-consuming alignment, enabling quick installation and saving time.

[0037] The first connecting portion 121 and the second connecting portion 22 can be connected by a hook and a hanging hole, or by a magnetic connection, etc., which is not further limited here. The second connecting portion 22 is movable along the second direction through the first housing 21 under the drive of the driving portion 23. The driving portion 23 can be a handle or a rod, which drives the second connecting portion 22 to reciprocate in the second direction through the principle of leverage.

[0038] The present invention utilizes a separate, milk-contacting collection assembly 10 and a non-contacting drive assembly 20. When the first housing 21 of the drive assembly 20 is detachably connected to the breast shield 11 of the collection assembly 10 in a first direction, the second connecting portion 22 of the drive assembly 20 is detachably connected to the first connecting portion 121 on the diaphragm 12. The drive assembly 23 drives the second connecting portion 22, which in turn drives the first connecting portion 121 and the diaphragm 12 to vibrate back and forth in a second direction, thereby applying negative pressure to the breast shield 11 or the milk storage cavity, causing milk to flow from the breast into the milk storage container 13 for temporary storage. After collecting milk and needing to be cleaned, the drive assembly 20 can be pulled away from the first direction to disengage the first connecting portion 121 from the second connecting portion 22, completing the quick and convenient separation of the collection assembly 10 and the drive assembly 20.

[0039] In an embodiment of the present invention, one of the second connecting portion 22 and the surface of the first connecting portion 121 away from the diaphragm 12 is provided with a first hooking portion 221, and the other is provided with a second hooking portion 1212. When the first shell 21 is connected to the breast shield 11, the first hooking portion 221 passes through and is confined to the second hooking portion 1212.

[0040] In this embodiment, the second connecting portion 22 and the first connecting portion 121 are removably connected by the cooperation of the second hooking portion 1212 and the first hooking portion 221. The first hooking portion 221 is oriented in the first direction, so that when the first shell 21 is connected to the breast shield 11, the first hooking portion 221 can be inserted into the corresponding second hooking portion 1212, thereby connecting the first connecting portion 121 and the second connecting portion 22. The second hooking portion 1212 can be formed by a hole formed in a protrusion 222 provided on the surface, or it can be formed directly in the surface. It is understood that in other embodiments, other types of removable connections between the second connecting portion 22 and the first connecting portion 121 can also be used, such as a snap-on connection, a plug-in connection, or a magnetic connection.

[0041] In an embodiment of the present invention, the number of the first hook portion 221 and the second hook portion 1212 are both two, the first hook portion 221 is spaced apart from the second connecting portion 22, the second hook portion 1212 is spaced apart from the first connecting portion 121, and a first hook portion 221 is passed through and limited to a second hook portion 1212.

[0042] In this embodiment, the first hook portion 221 and the second hook portion 1212 are symmetrically arranged on the parts on which they are arranged, which can ensure that the second connecting portion 22 is subjected to balanced force when pulling the first connecting portion 121, thereby ensuring balanced force on the diaphragm 12 and preventing the diaphragm 12 from being torn, causing the sealing of the manual breast pump 100 to fail.

[0043] In an embodiment of the present invention, the first connecting portion 121 and the diaphragm 12 are detachably connected. One of the first connecting portion 121 and the diaphragm 12 is provided with a latching protrusion 122 , and the other is provided with a latching groove 1211 . The latching protrusion 122 is latched and connected to the latching groove 1211 to connect the first connecting portion 121 and the diaphragm 12 .

[0044] In this embodiment, one of the first connecting portion 121 and the diaphragm 12 is provided with a latching protrusion 122, while the other is provided with a latching groove 1211. The interference fit between the latching protrusion 122 and the latching groove 1211 enables a detachable connection between the first connecting portion 121 and the diaphragm 12. Compared to directly providing the second hooking portion 1212 or the like on the diaphragm 12, this can reduce the pulling force on the diaphragm 12, thereby extending the service life of the manual breast pump 100.

[0045] In the embodiment of the present invention, one end of the driving portion 23 is connected to the second connecting portion 22, the middle portion of the driving portion 23 is rotatably connected to the surface of the first shell 21 facing away from the breast shield 11, and the other end of the driving portion 23 is disposed away from the surface of the first shell 21;

[0046] The other end of the pressing driving portion 23 is moved closer to the first housing 21 , and one end of the driving portion 23 is moved away from the first housing 21 , thereby driving the second connecting portion 22 to move in the second direction.

[0047] In this embodiment, one end of the driving part 23 is connected to the second connecting part 22, and the middle part of the driving part 23 is rotatably connected to the surface of the first shell 21. There is a gap between the other end of the driving part 23 and the first shell 21. When the other end of the driving part 23 is pressed, the driving part 23 rotates with the middle part as the axis, so that one end of the driving part 23 moves away from the first shell 21, thereby driving the second connecting part 22 to move relative to the first shell 21 in the second direction, and finally driving the diaphragm 12 to vibrate back and forth in the second direction, converting the rotational motion of the driving part 23 relative to the first shell 21 into a linear motion of the second connecting part 22 in the second direction, penetrating the first shell 21, thereby reducing the space occupied by the driving part 23 and reducing the volume of the manual breast pump 100.

[0048] In an embodiment of the present invention, a protrusion 222 is provided on a surface of the second connecting portion 22 facing away from the first connecting portion 121, the first shell 21 is provided with an avoidance hole, one end of the driving portion 23 is provided with a connecting hole, the protrusion 222 is provided with a threaded hole, and the threaded connecting member passes through the connecting hole and is threadedly connected to the threaded hole to connect the second connecting portion 22 and one end of the driving portion 23.

[0049] In this embodiment, the second connecting portion 22 is provided with a protrusion 222 on the surface facing the first housing 21. Accordingly, a clearance hole is provided on the first housing 21. The protrusion 222 is inserted into the clearance hole, guiding the second connecting portion 22 and preventing it from deflecting or even falling off, which could cause connection failure. The protrusion 222 is also provided with a threaded hole. Accordingly, one end of the driving portion 23 is provided with a connecting hole. A threaded connector passes through the connecting hole and is threadedly connected to the threaded hole in the protrusion 222, thereby connecting the second connecting portion 22 to the driving portion 23.

[0050] In the embodiment of the present invention, there are two driving parts 23 . One end of each driving part 23 is connected to the protrusion 222 , and the middle portions of the two driving parts 23 are rotatably connected to two opposite sides of the first housing 21 .

[0051] In this embodiment, two drive units 23 are symmetrically positioned on either side of the first housing 21, further evenly distributing force, saving effort and improving milking efficiency. One end of each drive unit 23 is connected to the protrusion 222 of the second connecting portion 22, and the middle portion is pivotally connected about the opposite sides of the first housing 21.

[0052] In an embodiment of the present invention, the drive assembly 20 also includes an elastic member 24, which is ring-arranged on the protrusion 222, and one end of the elastic member 24 abuts against the edge surface of the avoidance hole toward the second connection part 22, and the other end abuts against the surface of the second connection part 22 toward the first shell 21.

[0053] In this embodiment, an elastic member 24 is provided between the second connecting portion 22 and the first shell 21. The elastic member 24 is sleeved on the protrusion 222, and one end of the elastic member 24 abuts the second connecting portion 22, and the other end abuts the first shell 21. When the other end of the driving portion 23 is pressed, one end of the driving portion 23 drives the second connecting portion 22 to move along the second direction, and the elastic member 24 is compressed. After releasing the hand, the elastic member 24 recovers the deformation and releases the elastic force, so that the second connecting portion 22 is reset and the driving portion 23 is driven to reset. No manual reset is required, which saves manpower and improves milk sucking efficiency.

[0054] In the embodiment of the present invention, the first shell 21 is further provided with a guide hole, and the outer periphery of the second connecting portion 22 is provided with a side wall, which is movably inserted into the guide hole to guide the second connecting portion 22 .

[0055] In this embodiment, a side wall of a protrusion 222 is additionally provided on the outer periphery of the second connecting portion 22 . The side wall can slide along the guide hole, thereby further enhancing the smoothness of the movement of the second connecting portion 22 .
