[0033] Refer to the attached drawings of the specification of this utility model Figures 9 to 11 A breast pump according to a preferred embodiment of the present invention will be disclosed and described in the following description, wherein the breast pump comprises at least one wearable breast pumping device 100, a host 200 and at least one air tube 300, wherein the opposite ends of the air tube 300 are respectively connected to the wearable breast pumping device 100 and the host 200, wherein a part of the wearable breast pumping device 100 can be placed in a bra 400, and the bra 400 fixes the wearable breast pumping device 100 at the position of the breast 500. When the host 200 is working, the wearable breast pumping device 100 can help the mother to suck milk.

[0034] Preferably, in the attached Figures 9 to 11In this specific example of the breast pump of the present invention, the number of the wearable breast pumping devices 100 is two, and the air tube 300 may be in a "Y" shape, with one end of the air tube 300 connected to the host 200, and the other two ends are respectively connected to the two wearable breast pumping devices 100, so that the user can use the breast pump to suck milk from two breasts 500 at the same time. It can be understood that in some examples of the breast pump of the present invention, the number of the air tube 300 may also be two, and one end of each air tube 300 is respectively connected to each wearable breast pumping device 100, and the other end is respectively connected to the host 200. In other examples of the breast pump of the present invention, the number of the wearable breast pumping device 100 may also be one.

[0035] Next, refer to the attached Figures 1 to 8 , which shows the specific structure of the wearable breast pumping device 100. The wearable breast pumping device 100 includes a negative pressure forming unit 10 and a milk bottle 20 installed on the negative pressure forming unit 10, wherein the connection position between the negative pressure forming unit 10 and the milk bottle 20 has a smaller size so that the negative pressure forming unit 10 and the milk bottle 20 form an "8" shape. The shape of a letter "B" or "B". In this way, when the wearable breast pumping device 100 is fixed to the position of the breast 500 through the bra 400, the negative pressure forming unit 10 is placed in the bra 400 and wrapped by the bra 400, and the milk bottle 20 is suspended outside the bra 400. The connection position of the negative pressure forming unit 10 and the milk bottle 20 corresponds to the lower edge of the bra 400. Since the connection position of the negative pressure forming unit 10 and the milk bottle 20 has a smaller size, on the one hand, the distance between the lower edge of the bra 400 and the lower edge of the breast 500 can be reduced when supported by the wearable breast pumping device 100, thereby preventing the bra 400 from exerting greater pressure on other parts of the lower edge of the breast 500 at other parts of the lower edge. On the other hand, the bra 400 can hold the negative pressure forming unit 10 upwards to prevent the wearable breast pumping device 100 from sliding down or falling.

[0036] At the same time, since the wearable breast pumping device 100 only needs to place the negative pressure forming unit 10 in the bra 400, the size of the part of the wearable breast pumping device 100 placed in the bra 400 is relatively small. When the wearable breast pumping device 100 is fixed to the position of the breast 500 through the bra 400, the negative pressure forming unit 10 will not excessively push the bra 400 outwards, and the pressure applied by the bra 400 to the breast 500 through the wearable breast pumping device 100 will also be reduced, thereby improving the comfort of the mother when sucking milk through the wearable breast pumping device 100.

[0037] In the wearable breast pump device 100 of the present invention, the milk bottle 20 has a fitting side 201 and a side 202 facing away from the fitting side 201. In a cross-sectional position perpendicular to the height direction of the milk bottle 20, the curvature of the milk bottle 20 at the fitting side 201 is smaller than the curvature of the milk bottle 20 at the side facing away from the side 202, so that the fitting side 201 of the milk bottle 20 is flatter than the side facing away from the side 202. Figure 8 In this way, when the wearable breast pump device 100 is fixed to the position of the breast 500 through the bra 400, the bra 400 presses the fitting side 201 of the bottle 20 to the lower part of the breast 500. The flat fitting side 201 increases the contact area between the bottle 20 and the lower part of the breast 500, avoiding the discomfort caused by the long-term contact between the bottle 20 and the lower part of the breast 500.

[0038] That is to say, in this specific example of the wearable breast pumping device 100 of the present invention, by designing the negative pressure forming unit 10 and the milk bottle 20 of the wearable breast pumping device 100 to be roughly in the shape of "8" or "B", and designing the milk bottle 20 so that the curvature of the milk bottle 20 on the fitting side 201 is smaller than the curvature of the milk bottle 20 on the away side 202, not only can the bra 400 be prevented from causing greater pressure on other parts of the breast 500, but the flat fitting side 201 can also increase the contact area between the milk bottle 20 and the lower part of the breast 500, thereby avoiding the discomfort caused by the milk bottle 20 contacting the lower part of the breast 500 for a long time.

[0039] The negative pressure forming unit 10 has a space-variable milk suction chamber 101, and a receiving opening 102 and a milk discharge passage 103 respectively connected to the milk suction chamber 101. The milk bottle 20 has a milk storage chamber 203. After the milk bottle 20 is mounted on the negative pressure forming unit 10, the milk storage chamber 203 of the milk bottle 20 can be connected to the milk discharge passage 103 of the negative pressure forming unit 10. When the wearable milk suction device 100 is fixed to the position of the breast 500 through the bra 400, the breast 500 closes the receiving opening 102 of the negative pressure forming unit 10. As the space size of the milk suction chamber 101 of the negative pressure forming unit 10 changes rhythmically, milk is sucked out and can be discharged to the milk storage chamber 203 of the milk bottle 20 through the milk discharge passage 103 of the negative pressure forming unit 10.

[0040] Further, see Attachment Figures 1 to 8The negative pressure forming unit 10 includes a supporting shell 11, a negative pressure forming part 12 and a one-way valve 13. The supporting shell 11 has a gas exchange channel 111. The negative pressure forming part 12 is installed on the supporting shell 11. The negative pressure forming unit 10 forms a negative pressure chamber 104 between the supporting shell 11 and the negative pressure forming part 12. The negative pressure chamber 104 of the negative pressure forming unit 10 is communicated with the gas exchange channel 111 of the supporting shell 11. The milk suction chamber 101, the receiving opening 102 and the milk discharge channel 103 of the negative pressure forming unit 10 are all formed in the negative pressure forming part 12. The one-way valve 13 is installed on the negative pressure forming part 12 to selectively open or close the milk discharge channel 103 of the negative pressure forming unit 10. The milk bottle 20 is mounted on the negative pressure forming unit 12. When the one-way valve 13 opens the milk discharge passage 103 of the negative pressure forming unit 10, the milk discharge passage 103 of the negative pressure forming unit 10 is allowed to communicate with the milk holding chamber 203 of the milk bottle 20. Correspondingly, when the one-way valve 13 closes the milk discharge passage 103 of the negative pressure forming unit 10, the milk discharge passage 103 of the negative pressure forming unit 10 is prevented from communicating with the milk holding chamber 203 of the milk bottle 20. In other words, the one-way valve 13 is used to control the communication state between the milk holding chamber 203 of the milk bottle 20 and the milk discharge passage 103 of the negative pressure forming unit 10. Preferably, the negative pressure forming unit 12 is detachably mounted on the supporting shell 11.

[0041] In the present invention, the gas exchange channel 111 of the support shell 11 can be connected to the host 200 through the air tube 300. When the mother fixes the wearable breast pump device 100 at the position of the breast 500 through the bra 400, the breast 500 closes the receiving opening 102 of the negative pressure forming unit 10 to allow the negative pressure forming part 12 to cover the nipple, so that the breast 500 and the one-way valve 13 can form a closed space for the milk suction cavity 101 of the negative pressure forming unit 10. When the host 200 is working, the air in the negative pressure chamber 104 of the negative pressure forming unit 10 can be discharged through the gas exchange channel 111 of the supporting shell 11 and the trachea 300 to reduce the pressure of the negative pressure chamber 104 of the negative pressure forming unit 10. At this time, the one-way valve 13 closes the milk discharge channel 103 of the negative pressure forming unit 10, and the space of the milk suction chamber 101 of the negative pressure forming unit 10 increases, resulting in a decrease in the pressure of the negative pressure chamber 104 to suck out the milk. Subsequently, the air of the external environment can be discharged through the trachea 300 and the gas exchange channel 111 of the supporting shell 11. The channel 111 enters the negative pressure chamber 104 of the negative pressure forming unit 10, and the pressure of the negative pressure chamber 104 of the negative pressure forming unit 10 increases. At this time, the one-way valve 13 opens the milk discharge channel 103 of the negative pressure forming unit 10 to discharge milk, and the space of the milk suction chamber 101 of the negative pressure forming unit 10 is reduced, resulting in an increase in the pressure of the milk suction chamber 101. By alternately reducing and increasing the pressure of the negative pressure chamber 104 of the negative pressure forming unit 10, the pressure of the milk suction chamber 101 of the negative pressure forming unit 10 can also be alternately increased and decreased, so that the breast pump can achieve milk suction.

[0042] Continue to refer to the attached Figures 1 to 8 The negative pressure forming unit 10 further includes an outer cover shell 14 and an anti-slip portion 15. The support shell 11 is installed on one side of the outer cover shell 14, and at least a part of the support shell 11 is hidden by the outer cover shell 14. The anti-slip portion 15 is arranged on the other side of the outer cover shell 14. When the mother fixes the wearable breast pump device 100 on the position of the breast 500 through the bra 400, the anti-slip portion 15 is in direct contact with the bra 400, thereby increasing the friction between the negative pressure forming unit 10 and the bra 400, and preventing the wearable breast pump device 100 from sliding down or falling.

[0043] In the attached Figures 1 to 8In the specific example of the wearable breast pump device 100 shown, the anti-slip portion 15 is made of a silicone material and is mounted on the side of the outer shell 14 away from the support shell 11, or the anti-slip portion 15 is integrally formed on the side of the outer shell 14 away from the support shell 11, so as to set the anti-slip portion 15 on the outer shell 14. Preferably, the outer shell 14 has an embedding groove 140, the depth dimension of the embedding groove 140 is consistent with the thickness dimension of the anti-slip portion 15, and the anti-slip portion 15 is set in the embedding groove 140 of the outer shell 14, so that the edge of the anti-slip portion 15 can be prevented from being higher than the outer shell 14, which can not only ensure the aesthetics of the wearable breast pump device 100, but also prevent the edge of the anti-slip portion 15 from warping outward when the wearable breast pump device 100 is used for a long time. Optionally, in other specific examples of the wearable breast pump device 100 of the present invention, the anti-slip portion 15 may also be formed by roughening the outer surface of the side of the outer cover shell 14 that is away from the supporting shell 11 .

[0044] Continue to refer to the attached Figures 1 to 8 The negative pressure forming unit 10 includes an airway portion 16, which is arranged between the supporting shell 11 and the outer cover shell 14. The gas exchange channel 111 of the supporting shell 11 is connected to the airway portion 16, and one end of the air pipe 300 is connected to the airway portion 16. In this way, the air pipe 300 can be connected to the negative pressure chamber 104 of the negative pressure forming unit 10 through the airway portion 16 and the gas exchange channel 111 of the supporting shell 11.

[0045] Specifically, the support shell 11 includes a shell body 112 and a horn body 113 integrally extending outward from one end of the shell body 112, the shell body 112 has an installation cavity 1121 and an installation opening 1122 connected to the installation cavity 1121, the top of the shell body 112 of the support shell 11 has a shell insert arm 1123, the opening of the gas exchange channel 111 is formed at the end surface of the shell insert arm 1123, wherein the negative pressure forming portion 12 includes a deformation portion 121 and a skeleton portion 122, the deformation portion 121 has a combination end 1211 and a deformation end 1212 corresponding to the combination end 1211, the skeleton portion 122 is combined with the The coupling end 1211 of the deformation part 121, the milk suction chamber 101 and the receiving opening 102 of the negative pressure forming unit 10 are both formed at the deformation part 121, a part of the milk discharge channel 103 of the negative pressure forming unit 10 is formed at the deformation part 121, and the other part is formed at the skeleton part 122, wherein the skeleton part 122 of the negative pressure forming part 12 is installed at the installation opening 1122 of the shell body 112, the deformation part 121 extends to the installation chamber 1121 through the installation opening 1122 of the shell body 112, and the negative pressure chamber 104 of the negative pressure forming unit 10 is formed between the deformation part 121 and the shell body 112.

[0046] When the host 200 is working, the air in the negative pressure chamber 104 of the negative pressure forming unit 10 is discharged through the gas exchange channel 111 of the supporting shell 11, the airway portion 16 and the trachea 300 to reduce the pressure in the negative pressure chamber 104 of the negative pressure forming unit 10. At this time, the one-way valve 13 closes the milk discharge channel 103 of the negative pressure forming unit 10, and the deformed end 1212 of the deformed portion 121 of the negative pressure forming portion 12 is deformed toward the end close to the shell body 112 and away from the horn body 113 to increase the space of the milk suction chamber 101 of the negative pressure forming unit 10, thereby reducing the pressure in the milk suction chamber 101 and sucking milk out of the breast 500. As air from the external environment enters the negative pressure chamber 104 of the negative pressure forming unit 10 through the trachea 300, the airway portion 16 and the gas exchange channel 111 of the supporting shell 11, the pressure in the negative pressure chamber 104 of the negative pressure forming unit 10 increases. At this time, the one-way valve 13 opens the milk discharge channel 103 of the negative pressure forming unit 10 to discharge milk to the milk bottle 20, and the deformed end 1212 of the deformed portion 121 of the negative pressure forming portion 12 is deformed toward an end away from the shell main body 112 and away from the horn body 113, so as to reduce the space of the milk suction chamber 101 of the negative pressure forming unit 10, thereby causing the pressure in the milk suction chamber 101 to increase.

[0047] Reference Figure 6 The bottom of the frame portion 122 of the negative pressure forming part 12 has an internal mounting arm 1221, and the one-way valve 13 is mounted on the internal mounting arm 1221 to mount the one-way valve 13 on the negative pressure forming part 12. Preferably, the one-way valve 13 is a duckbill valve, and as the pressure of the milk suction chamber 101 of the negative pressure forming unit 10 changes, the one-way valve 13 can be opened and closed, so that the one-way valve 13 controls the communication state between the milk holding chamber 203 of the milk bottle 20 and the milk discharge channel 103 of the negative pressure forming unit 10. Preferably, the one-way valve 13 is detachably mounted on the internal mounting arm 1221 of the frame portion 122 of the negative pressure forming part 12.

[0048] Reference Figures 3 to 8 The airway portion 16 includes an air guide seat 161 and a reversing seat 162, wherein the air guide seat 161 has a first airway 1611 extending transversely and a bottom plug hole 1612 and a top plug hole 1613 respectively connected to the first airway 1611, and the air guide seat 161 is arranged on the top of the shell body 112 in a manner that the shell plug arm 1123 of the shell body 112 is inserted into the bottom plug hole 1612, wherein the reversing seat 162 has a bottom plug arm 1621, a side plug arm 1622 and a second airway 1 623, one opening of the second air duct 1623 is formed at the end face of the bottom plug arm 1621, and the other opening is formed at the end face of the side plug arm 1622, and the bottom plug arm 1621 of the reversing seat 162 is inserted into the top plug hole 1613 of the air guide seat 161, so that the negative pressure chamber 104 of the negative pressure forming unit 10, the gas exchange channel 111 of the supporting shell 11, the first air duct 1611 of the air guide seat 161 and the second air duct 1623 of the reversing seat 162 are connected in sequence.

[0049] In the attached Figures 1 to 8 In the specific example of the wearable breast pump device 100 shown, by arranging the air guide seat 161 and the reversing seat 162 on the top of the shell body 112 of the support shell 11, the part of the wearable breast pump device 100 for connecting the air pipe 300 (i.e., the side insert arm 1622 of the reversing seat 162) can be arranged at a reasonable position to avoid the part from occupying a large space. In other words, the arrangement of the air guide seat 161 and the reversing seat 162 of the airway portion 16 can realize the miniaturization of the wearable breast pump device 100.

[0050] In the attached Figures 1 to 8In the specific example of the wearable breast pumping device 100 shown, the bottom insertion arm 1621 of the reversing seat 162 is detachably inserted into the top insertion hole 1613 of the air guide seat 161, so that the mother can choose the orientation of the side insertion arm 1622 of the reversing seat 162 as needed. For example, the mother can allow the bottom insertion arm 1621 of the reversing seat 162 to be inserted into the top insertion hole 1613 of the air guide seat 161 with the side insertion arm 1622 of the reversing seat 162 facing the left side as needed, or can allow the bottom insertion arm 1621 of the reversing seat 162 to be inserted into the top insertion hole 1613 of the air guide seat 161 with the side insertion arm 1622 of the reversing seat 162 facing the right side as needed. In this way, the mother does not need to distinguish between the two wearable breast pumping devices 100 during the process of assembling the breast pump.

[0051] In the attached Figures 1 to 8 In the specific example of the wearable breast pump device 100 shown, the outer shell 14 has a positioning hole 141, and the outer shell 14 is fixedly mounted on the outer edge of the horn body 113 of the support shell 11 to form a receiving chamber 105 of the negative pressure forming unit 10 between the support shell 11 and the outer shell 14, and the positioning hole 141 of the outer shell 14 is connected to the receiving chamber 105 of the negative pressure forming unit 10. The air guide seat 161 has a top boss 1614, and the opening of the top plug hole 1613 is formed at the end surface of the top boss 1614. The air guide seat 161 is received in the receiving chamber 105 of the negative pressure forming unit 10, and the top boss 1614 of the air guide seat 161 extends to the positioning hole 141 of the outer shell 14. It can be understood that since the shell insert arm 1123 of the shell body 112 of the supporting shell 11 is inserted into the bottom socket 1612 of the air guide seat 161 and the top boss 1614 of the air guide seat 161 extends to the positioning hole 141 of the outer cover shell 14, the air guide seat 161 is stably accommodated in the accommodating cavity 105 of the negative pressure forming unit 10, and the air guide seat 161 will not shift regardless of whether the bottom insert arm 1621 of the reversing seat 162 is inserted into the top socket 1613 of the air guide seat 161 or the bottom insert arm 1621 of the reversing seat 162 is pulled out from the top socket 1613 of the air guide seat 161.

[0052] Furthermore, the top of the shell body 112 of the supporting shell 11 has a positioning wall 1124, the positioning wall 1124 surrounds the bottom of the air guide seat 161, and the inner wall of the positioning wall 1124 fits the outer wall of the air guide seat 161. In this way, on the one hand, before the outer cover shell 14 is assembled to the supporting shell 11, the positioning wall 1124 of the shell body 112 can pre-position the air guide seat 161, so that when the outer cover shell 14 is assembled to the supporting shell, the positioning wall 1124 of the shell body 112 can pre-position the air guide seat 161. During the process, the positioning wall 1124 of the shell body 112 can prevent the air guide seat 161 from being misplaced, thereby improving the assembly efficiency. On the other hand, when the bottom insert arm 1621 of the reversing seat 162 is inserted into the top plug hole 1613 of the air guide seat 161 or the bottom insert arm 1621 of the reversing seat 162 is pulled out from the top plug hole 1613 of the air guide seat 161, the positioning wall 1124 of the shell body 112 can prevent the air guide seat 161 from being shifted.

[0053] The outer cover shell 14 includes an outer shell 142 and an anti-detachment cover 143, the positioning hole 141 is formed in the anti-detachment cover 143, wherein the outer shell 142 has a shell channel 1421, and the outer shell 142 is fixedly installed on the outer edge of the speaker body 113 of the support shell 11, and the position of the top boss 1614 of the air guide seat 161 corresponds to the position of the shell channel 1421 of the outer shell 142, wherein the anti-detachment cover 143 is fixedly installed on the shell channel 1421 of the outer shell 142 in a manner that the top boss 1614 of the air guide seat 161 is inserted into the positioning hole 141 of the outer cover shell 14, in this way, the support shell 11, the air guide seat 161 and the outer cover shell 14 can be conveniently installed, and the misalignment of the air guide seat 161 can be avoided.

[0054] In the attached Figures 1 to 8In the example of the wearable breast pump device 100 shown, the bottom of the shell body 112 of the supporting shell 11 has a mounting notch 1125, and the bottom of the skeleton part 122 of the negative pressure forming part 12 has an external mounting arm 1222, the external mounting arm 1222 surrounds the internal mounting arm 1221, and the external mounting arm 1222 can be held in the mounting notch 1125 of the shell body 112, wherein the milk bottle 20 is mounted on the external mounting arm 122 of the skeleton part 122. Arm 1222, so that: on the one hand, the sucked milk can be collected into the feeding bottle 20, on the other hand, the frame portion 122 is held above the portion of the shell body 112 for forming the mounting notch 1125, and the feeding bottle 20 is held below, so that the frame portion 122 and the feeding bottle 20 clamp the portion of the shell body 112 for forming the mounting notch 1125 on opposite sides, so as to further ensure that the negative pressure forming portion 12 is reliably and stably mounted on the supporting shell 11.

[0055] The external mounting arm 1222 of the skeleton portion 122 of the negative pressure forming portion 12 has at least one clamping groove 12221 extending in the circumferential direction and at least one guide groove 12222 extending in the height direction and connected to one end of the clamping groove 12221. The bottle mouth of the milk bottle 20 has at least one clamping protrusion 21. The clamping protrusion 21 of the milk bottle 20 can slide into the clamping groove 12221 through the guide groove 12222 of the external mounting arm 1222 of the skeleton portion 122 to install the milk bottle 20 on the external mounting arm 1222 of the skeleton portion 122.

[0056] Continue to refer to the attached Figures 1 to 8 In this specific example of the wearable breast pumping device 100 of the present invention, the negative pressure forming unit 10 includes a suction cup bra 17, which is assembled on the negative pressure forming part 12, wherein the suction cup bra 17 can be adsorbed on the breast 500 to prevent the wearable breast pumping device 100 from automatically sliding down or falling, and the suction cup bra 17 isolates the negative pressure forming part 12 and the breast 500, which is not only conducive to improving the comfort of the wearable breast pumping device 100, but also conducive to ensuring the hygiene of the wearable breast pumping device 100.

[0057] Further, the suction cup bra 17 includes a shoulder ring 171, a fitting ring 172 and a speaker cover 173, wherein the fitting ring 172 integrally extends to one side from the inner edge of the shoulder ring 171, and the speaker cover 173 integrally extends to the opposite direction from the outer edge of the shoulder ring 171. In other words, the suction cup bra 17 is a whole. For example, in some embodiments, the suction cup bra 17 can be made of silicone injection molding, so that the suction cup bra 17 is flexible and integral, so that the suction cup bra 17 can directly hang the wearable breast pumping device 100 on the breast 500 by adsorbing the breast 500.

[0058] The assembly ring 172 of the suction cup bra 17 is assembled to the installation opening 1121 of the shell body 112. When the mother uses the suction cup bra 17 to absorb the wearable milk pumping device 100 onto the breast 500, the speaker cover 173 of the suction cup bra 17 directly fits the breast 500, and the opening of the speaker cover 173 is closed by the breast 500. In this way, on the one hand, the speaker cover 173 and the negative pressure forming unit 10 are far apart. When the mother needs to absorb the wearable milk pumping device 100 onto the breast 500 through the suction cup bra 17, the speaker cover 173 can be turned outward first, and after the nipple is aligned with the milk suction cavity 101 of the negative pressure forming unit 10, the speaker cover 173 can be restored. 173, so that the horn cover 173 is closely attached to the breast 500, so that the breast 500 can close the opening of the horn cover 173 to close the receiving opening 102 of the negative pressure forming unit 10, thereby allowing the suction cup bra 17 to be adsorbed on the breast 500 and the wearable breast pumping device 100 to be directly hung on the breast 500 by the suction cup bra 17, and during the milk pumping process, the milk suction cavity 101 of the negative pressure forming unit 10 and the internal space of the suction cup bra 17 form a negative pressure environment, so that the wearable breast pumping device 100 can be reliably hung on the breast 500, that is, in the When the breast pump does not start working, the suction cup bra 17 can directly hang the wearable breast pumping device 100 on the breast 500. When the breast pump is working, since the milk suction cavity 101 of the negative pressure forming unit 10 and the internal space of the suction cup bra 17 form a negative pressure environment, the suction cup bra 17 can more reliably hang the wearable breast pumping device 100 on the breast 500. On the other hand, after the mother directly hangs the wearable breast pumping device 100 on the breast 500 through the suction cup bra 17, the suction cup bra 17 isolates the negative pressure forming unit 10 and the breast 500 to avoid the negative pressure forming The negative pressure generating unit 10 directly contacts the breast 500, and the flexible suction cup bra 17 can improve the comfort of the mother when using the breast pump; on the other hand, when the assembly ring body 172 of the suction cup bra 17 changes with the position of the negative pressure generating unit 10, the shoulder ring body 171 of the suction cup bra 17 can be deformed to prevent the horn cover body 173 from changing with the position of the negative pressure generating unit 10, so that during the milk pumping process, the suction cup bra 17 can always be reliably adsorbed on the mother's breast 500, thereby preventing the wearable milk pumping device 100 from falling off the breast 500 and leaking milk.

[0059] In the attached Figures 1 to 8In one example of the wearable breast pump device 100 shown, the assembly ring 172 of the suction cup bra 17 is detachably assembled to the negative pressure forming part 12, so that the suction cup bra 17 can be easily cleaned to improve the hygiene of the breast pump. At the same time, the mother can choose a suitable suction cup bra 17 according to her own needs to meet personalized needs. For example, the suction cup bra 17 of different materials, different sizes, and different shapes can all be selected and assembled to the same negative pressure forming part 12.

[0060] In the attached Figures 1 to 8 In the specific example of the wearable breast pump device 100 shown, the outer diameter of the mounting ring 172 of the suction cup bra 17 is consistent with the inner diameter of the negative pressure forming part 12, so that based on the friction force generated between the outer wall of the mounting ring 172 and the inner wall of the negative pressure forming part 12, the mounting ring 172 of the suction cup bra 17 can be reliably assembled to the negative pressure forming part 12.

[0061] Reference Figure 6 The assembly ring 172 of the suction cup bra 17 extends through the installation opening 1121 of the shell body 112 to the outside of the installation cavity 1122 of the shell body 112 to form a step. In this way, the sucked milk can be blocked by the assembly ring 172 to prevent the milk from flowing to the position of the horn cover 173, thereby preventing the milk from leaking from the fitting position of the horn cover 173 and the breast 500. In this way, not only can the milk sucking process be made more comfortable, but also the suction cup bra 17 can be prevented from falling off the breast 500, so as to ensure that the wearable breast pumping device 100 is reliably hung on the breast 500. In other words, by allowing the mounting ring 172 of the suction cup bra 17 to extend to the outside of the mounting cavity 1122 of the shell body 112 through the mounting opening 1121 of the shell body 112, the sucked milk is only allowed to be discharged through the milk discharge channel 103 of the negative pressure forming unit 10.

[0062] Reference Figure 6The suction cup bra 17 further includes a limiting portion 174, which extends integrally from the peripheral wall of the assembly ring body 172 in a direction substantially perpendicular to the extension direction of the assembly ring body 172, and there is a gap between the limiting portion 174 and the shoulder ring body 171. In this way, when the assembly ring body 172 of the suction cup bra 17 is assembled to the mounting opening 1121 of the shell body 112, the limiting portion 174 limits the assembly depth of the assembly ring body 172 by abutting against the negative pressure forming portion 12, so that: on the one hand, the limiting portion The positioning portion 174 can ensure that there is a spacing between the shoulder ring body 171 and the negative pressure forming portion 12, so that when the assembly ring body 172 changes with the position of the negative pressure forming unit 10, the shoulder ring body 171 can be deformed. On the other hand, the limiting portion 174 can ensure that the assembly ring body 172 extends through the assembly opening 122 of the negative pressure forming portion 12 to the outside of the milk discharge channel 123 of the negative pressure forming portion 12 to form the step, thereby preventing the assembly ring body 172 from covering the milk discharge channel 103 of the negative pressure forming unit 10 to ensure smooth milk discharge.

[0063] In the attached Figures 1 to 8 In the specific example of the wearable breast pump device 100 shown, the limiting portion 174 of the suction cup bra 17 is annular, and the distance between the outer side of the limiting portion 174 and the central axis of the suction cup bra 17 is greater than the distance between the outer side of the shoulder ring body 171 and the central axis of the suction cup bra 17, so that from the top view of the suction cup bra 17 (the angle perpendicular to the central axis of the suction cup bra 17), the limiting portion 174 covers the shoulder ring body 171, so that the shoulder ring body 171 is visually invisible.
