[0044] The present application will be described in conjunction with the accompanying drawings. DETAILED DESCRIPTION

[0045] Although specific configurations and arrangements are discussed in this application, it should be understood that the discussion of these specific configurations and arrangements is only for illustrative purposes. Those skilled in the art will recognize that other configurations and arrangements may also be used without departing from the spirit and scope of this application. For those skilled in the art, this application is obviously also applicable to various other applications.

[0046] It should be noted that the phrases "one embodiment", "embodiment", "example embodiment", "some embodiments", etc. mentioned in the specification indicate that the described embodiment may include specific features, structures or characteristics, but not every embodiment necessarily includes specific features, structures or characteristics. In addition, these phrases do not necessarily refer to the same embodiment. Moreover, when describing specific features, structures or characteristics in conjunction with an embodiment, whether or not explicitly described, those skilled in the art should understand that these features, structures or characteristics may be affected in conjunction with other implementations.

[0047] Generally, terms can be understood, at least in part, from the context of use. For example, the term "one or more" as used herein (based at least in part on the context) can be used to describe any feature, structure, or characteristic in a singular sense, and can also be used to describe a combination of features, structures, or characteristics in a plural sense. Similarly, based at least in part on the context, the terms "a", "an", or "the" can also be understood to express singular or plural usage. In addition, the term "based on" can also be understood to not necessarily be intended to express an exclusive set of factors, but, based at least in part on the context, can allow for the presence of other factors that are not necessarily explicitly described.

[0048] It should be easily understood that, in the present application, the meanings of “on”, “above” and “above” should be interpreted in the broadest manner.

In addition to the orientation described in the figure, the spatially relative terms are also intended to include different orientations of the device when in use or operation. The device can also be oriented in other directions (rotated 90 degrees or in other orientations), and the spatially relative descriptors used herein can also be interpreted accordingly. In addition, the terms "coupled", "coupled to" or "coupled between..." can be understood as not necessarily "physically connected or attached", that is, directly attached, and can also be understood as indirectly connected through an intermediate component.

[0050] A breast pump is a medical device or wearable device used to help a nursing mother express milk. The general principle of a breast pump is to generate suction through a pump to generate negative pressure through a suction diaphragm, thereby sucking out the milk. However, existing breast pumps have some problems in terms of installation, fixing and sealing of the suction diaphragm. For example, due to improper installation, some unwanted gaps between the suction diaphragm and the air circuit may cause liquid (such as milk) or water to overflow or leak, thereby increasing the risk of milk contamination. In addition, these unwanted gaps between the suction diaphragm and the air circuit may also cause the suction pressure to decrease, thereby reducing the efficiency and effectiveness of the pump. For another example, the milk container of some existing breast pumps cannot be easily removed from the main unit, thereby affecting the use of the product. In addition, during the disassembly process or during the process of pouring milk from the milk container, the suction diaphragm may also be removed from the main unit, thereby increasing the probability of additional improper installation each time the milk container is removed from the main unit. Furthermore, although the suction diaphragm prevents moisture from entering the pump, some moisture (e.g., moisture remaining in the breast pump after cleaning) may still be drawn into the pump, causing the breast pump to malfunction.

[0051] In order to solve one or more of the above problems, the present application introduces a solution, wherein a diaphragm cover is detachably connected to a suction chamber and fixes the suction diaphragm to the suction chamber of the three-way pipe structure or the milk container. The diaphragm cover can limit and pre-press the suction diaphragm before installation, thereby avoiding various problems of improper installation. In some embodiments, the diaphragm cover can be fixed to the suction diaphragm during installation or during the process of pouring milk from the milk container, thereby reducing the possibility of milk overflow or leakage, or reducing the possibility of accidental removal of the suction diaphragm. By using the diaphragm cover, the pumping effect of milk can also be improved due to the pre-pressing and sealing of the suction diaphragm. In some embodiments, different solutions are also introduced to prevent moisture or liquid from being sucked into the pump, thereby effectively improving and extending the service life of the breast pump.

[0052] Figure 1A1 shows a side view of an exemplary breast pump 100 according to some aspects of the present application. Figure 1A As shown, the breast pump 100 includes a main housing 11 and one or more buttons 1111 disposed on the top of the main housing 11. The breast pump 100 may be at least partially wearable or placed in a bra. The button 1111 disposed on the top of the main housing 11 may be easily accessed or touched by the user to control the operation of the breast pump 100. In some embodiments, the button 1111 may be disposed in other parts of the main housing 11. In some embodiments, the button 1111 may include a power button, a switch button, or a control interface; wherein the user may start, stop or change the pumping cycle, increase or decrease the peak pumping pressure, or switch between different pre-programmed or predetermined pressure curves (e.g., to mimic the sucking pattern of a baby) on the control interface. The breast pump 100 may also include a power interface 1113 disposed on one side of the main housing 11. The power interface 1113 may charge the power supply of the breast pump or receive power provided from outside the breast pump 100. The power supply may be a battery or any other type of portable power supply. The main body housing 11 can accommodate the main body of the breast pump 100, including various components of the main body discussed later.

[0053] The breast pump 100 may also include a breast shield 13 that is detachably connected to the main housing 11. In some embodiments, the breast shield 13 may be connected to the main housing 11 by, for example, fastening, snapping, locking, or interfitting. When the breast shield 13 and the main housing 11 are connected to each other, the breast pump 100 may be leakproof, preventing water, moisture, and air from entering the breast pump 100. The breast shield 13 may be detachable from the main housing 11, thereby allowing a user to conveniently clean at least one of the breast shield 13 and the main housing 11. The breast shield 13 may have a concave surface on a side opposite to the main housing 11 to accommodate a breast of a nursing mother.

[0054] The breast pump 100 may further include a milk container 15. The milk container 15 is detachably connected to at least one of the main housing 11 and the breast shield 13. In some embodiments, the milk container 15 may be connected to the main housing 11 or the breast shield 13, or to both the main housing 11 and the breast shield 13, for example, by fastening, snapping, locking, or mutual cooperation. When the milk container 15 is connected to at least one of the main housing 11 and the breast shield 13, the breast pump 100 may be leakproof. When the milk container 15 is separated from at least one of the main housing 11 and the breast shield 13, the user may conveniently clean the milk container 15. In some embodiments, the milk container 15 may be detachably connected to at least one of the main housing 11 and the breast shield 13 through other components; wherein the other components are coupled between the milk container 15 and at least one of the main housing 11 and the breast shield 13. The milk container 15 is used to collect milk in the breast of a nursing mother after expressing the milk.

[0055] Figure 1B and Figure 1C 1 shows a side view of a partially disassembled breast pump 100 according to some aspects of the present application. Figure 1B As shown, the breast pump 100 may further include a three-way pipe structure 17, which is detachably connected to the breast shield 13, the milk container 15 and the main body housing 11. In some embodiments, the three-way pipe structure 17 may include a flange portion 173, which may be adapted to the nipple of the breast to collect milk through the path connected to the breast shield 13. The air path portion (not shown) is connected to the suction diaphragm unit 19 to provide suction pressure. The milk expression portion (not shown) is connected to the milk container 15 for guiding the milk into the milk container 15. In some embodiments, the three-way pipe structure 17 may include a threaded structure 171, which may be fastened to the milk container 15. In some embodiments, the flange portion 173 may be independent of the three-way pipe structure 17, for example, as a part of the breast shield 13. In some embodiments, the threaded structure 171 may be independent of the three-way pipe structure 17, for example, as a part of the milk container 15.

[0056] like Figure 1BAs shown, the suction diaphragm unit 19 may include a suction chamber 193, a suction diaphragm 191 detachably connected to the suction chamber 193, and a diaphragm cover 195 detachably connected to the suction chamber 193 and fixing the suction diaphragm 191 in a fixed position. In some embodiments, at least part of the components of the suction diaphragm unit 19 are connected to the three-way pipe structure 17 via a shaft 175, so that at least one of the diaphragm cover 195 or the suction diaphragm 191 can be turned over while still being connected to the suction chamber 193 or the three-way pipe structure 17. In this case, when cleaning the components of the breast pump 100, all components of the suction diaphragm unit 19 can remain connected to the three-way pipe structure 17, so that no components are left out during disassembly and assembly.

[0057] The shaft 175 may be separate from the suction diaphragm unit 19 or a part of the suction chamber 193. In some embodiments, the shaft 175 may be connected to the suction chamber 193 or the tee structure 17. In some embodiments, the suction chamber 193 and the diaphragm cover 195 may include a hard material, such as acrylonitrile butadiene styrene (ABS) plastic, polypropylene, polystyrene, nylon, polycarbonate, methacrylate, or a combination of at least two of these materials. The suction diaphragm 191 may include a resilient or elastic material, such as flexible plastic, silicone, rubber, resin, epoxy, or a combination of at least two of these materials. In some embodiments, the hardness of the material of the suction chamber 193 and the diaphragm cover 195 is greater than the hardness of the material of the suction diaphragm 191. In some embodiments, the material used for the suction diaphragm 191 is selected based on its ability to rebound to the high vacuum generated by the breast pump 100. The suction diaphragm 191 can be mounted on the edge of the suction chamber 193 and fit with the edge of the suction chamber 193 to achieve air sealing of the suction chamber. The diaphragm cover 195 can also include a protrusion 1951, which is used to fix the suction diaphragm 191 in a fixed position. By using the suction diaphragm 191, liquid or moisture in the milk container 15 or the three-way pipe structure 17 will be blocked by the suction diaphragm 191, thereby preventing moisture or liquid from being sucked into the pump and causing damage to the pump.

[0058] like Figure 1C As shown, when the diaphragm cover 195 is locked with the suction chamber 193 by the buckle 1955, the suction diaphragm 191 (as shown in FIG. Figure 1B 195 and the suction chamber 193. Therefore, even if the suction diaphragm 191 is improperly installed, it can be fixed between the diaphragm cover 195 and the suction chamber 193. In addition, as shown in FIG. Figure 1B and Figure 1CAs shown, the diaphragm cover 195 may further include a tubular structure 1953 connected to the air path connected to the pump. In some embodiments, the tubular structure 1953 can be inserted into the recessed area of ​​the pump. The air contained by the suction diaphragm 191 in the suction chamber 193 and between the suction diaphragm 191 and the diaphragm cover 195 can be discharged or discharged to the outside of the pump through the tubular structure 1953, thereby generating negative pressure in the suction chamber 193. The negative pressure can squeeze out the milk in the breast of the wearer of the breast pump 100, and the milk flows into the milk container 15 through the three-way pipe structure 17.

[0059] Figure 1D 1 shows a perspective view of an exemplary breast pump 100 according to some aspects of the present application. Figure 1D As shown, the suction hole 1115 of the main unit is coupled to the main unit housing 11 and can be connected to the tubular structure 1953 of the diaphragm cover 195. When the nipple of the breast is surrounded by the breast shield 13 and aligned with the flange portion 173, the pump in the main unit discharges the air contained in the suction diaphragm 191 in the suction chamber 193 through the first side of the suction diaphragm 191. When negative pressure acts on the first side of the suction diaphragm 191, the suction diaphragm 191 is deformed, and the air on the second side of the suction diaphragm 191 in the suction chamber 193 is discharged. Since the second side of the suction diaphragm 191 is connected to the three-way pipe structure 17 through an air path (not shown), negative pressure is also generated in the three-way pipe structure 17. Therefore, the nipple surrounded by the breast shield 13 and aligned with the flange portion 173 of the three-way pipe structure 17 can squeeze out milk, and the milk flows into the milk container 15 through the duckbill valve 121. The duckbill valve 121 allows milk to be released in one direction (i.e., flow from the three-way pipe structure 17 into the milk container 15), but not in the opposite direction. It should be noted that the duckbill valve disclosed in the present application is not limited to the duckbill valve shown in the figure, and it can be any other type of valve as long as the valve can prevent backflow or function as a one-way valve. The valve can have an elastic lip in a duckbill shape or any other shape to prevent backflow and allow forward flow.

[0060] In some embodiments, the pump disclosed in the present application may have a preprogrammed or predetermined pumping cycle, a pumping pressure peak, or a different preprogrammed or predetermined pressure curve (e.g., to mimic a baby's sucking pattern). In this case, the suction diaphragm 191 will also deform and recover according to the preprogrammed or predetermined pumping cycle, the pumping pressure peak, or the different preprogrammed or predetermined pressure curve. It should be noted that the pump disclosed below includes an air pump.

[0061] In some embodiments, the raised portion 1951 may include at least one of a concave or convex structure, a strip structure, and a raised structure formed on the inner surface of the raised portion 1951 and surrounding the opening of the tubular structure 1953. These structures formed on the inner surface of the raised portion 1951 can retain some liquid (such as water, milk, etc.) or moisture inside the breast pump (such as the suction diaphragm 191, the suction chamber 193 or other components), thereby preventing the liquid or moisture from being sucked into the pump and causing damage to the pump. It should be noted that the raised portion is only an example of being able to block liquid or moisture inside the breast pump, but is not limited to the embodiments of the present application, and other structures that can provide the same or similar technical effects can also be used.

[0062] Figure 1E FIG. 2 shows a bottom view of a main unit of an exemplary breast pump 100 according to some aspects of the present application. Figure 1E As shown, the suction hole 1115 of the main unit is connected to the main unit housing 11, so that the pump can discharge the air contained by the suction diaphragm 191 in the suction chamber 193. In addition, the inner surface 1117 of the main unit housing 11 is also rounded to match the shape of the breast shield 13 when installed.

[0063] Figure 1F 1 shows a perspective view of an exemplary breast pump 100 according to some aspects of the present application. Figure 1F As shown, the host includes one or more pumps 115, a power system 117 (including a power source, such as a battery), and a control circuit 119. The one or more pumps 115, the power system 117, and the control circuit 119 are connected to the host housing 11. The power system 117 is coupled to the pump 115, or to the control circuit 119, or to both the pump 115 and the control circuit 119, and is connected to the power interface 1113 (such as Figure 1A11) is connected to the breast pump battery or receives power from the power interface 1113. The control circuit 119 is connected to the pump 115 for controlling the operation of the pump 115. For example, the control circuit 119 can control the preprogrammed or predetermined pumping cycle, pumping pressure peak, or different preprogrammed or predetermined pressure curves (for example, to imitate the sucking pattern of the baby) of the pump 115. The control circuit 119 can also be coupled to the button 1111 so that the user can manually input instructions, or control the preprogrammed or predetermined pumping cycle, pumping pressure peak, or different preprogrammed or predetermined pressure curves through the button 1111. In some embodiments, the pump 115 may further include a solenoid valve (not shown) or be coupled to the solenoid valve. For example, in one example of the solenoid valve, the solenoid valve includes two channels (such as input and output) and a valve for controlling the opening or closing of the two channels, the pump 115 can always provide negative pressure, and the solenoid valve can open or close the valve between the two channels to allow the negative pressure to pass. That is, the solenoid valve can be used to control the cycle or curve of pumping. In some embodiments, the solenoid valve may also be controlled by the control circuit 119 .

[0064] Figure 2A 2 shows a side view of an exemplary breast pump 200 according to some aspects of the present application. Figure 2A As shown, the breast pump 200 includes a main body housing 21, and one or more buttons (not shown) that can be arranged on the top of the main body housing 21. The breast pump 200 can be at least partially wearable or placed in a bra. The main body housing 21 can further include a power interface (not shown), which can charge the power supply of the breast pump or receive power provided by the outside of the breast pump 200 through the power interface. The main body housing 21 can accommodate the main body of the breast pump 200, including multiple components of the main body. These components can be connected to Figures 1A to 1F The components of the breast pump 100 shown in FIG. 1 are the same or similar.

[0065] The breast pump 200 may also include a breast shield 23 that is detachably connected to the main housing 21. In some embodiments, the breast shield 23 may be connected to the main housing 21 by, for example, fastening, snapping, locking, or interfitting. When the breast shield 23 and the main housing 21 are connected to each other, the breast pump 200 may be leakproof, preventing water, moisture, and air from entering the breast pump 200. The breast shield 23 may be detachable from the main housing 21, thereby allowing a user to conveniently clean at least one of the breast shield 23 and the main housing 21. The breast shield 23 may have a concave surface on a side opposite to the main housing 21 to accommodate a breast of a nursing mother.

[0066] The breast pump 200 may further include a milk container 25. The milk container 25 is detachably connected to at least one of the main housing 21 and the breast shield 23. In some embodiments, the milk container 25 may be connected to the main housing 21 or the breast shield 23, or to both the main housing 21 and the breast shield 23, for example, by fastening, snapping, locking, or mutual cooperation. When the milk container 25 is connected to at least one of the main housing 21 and the breast shield 23, the breast pump 200 may be leakproof. When the milk container 25 is separated from at least one of the main housing 21 and the breast shield 23, the user may conveniently clean the milk container 25. In some embodiments, the milk container 25 may be detachably connected to at least one of the main housing 21 and the breast shield 23 through other components; wherein the other components are coupled between the milk container 25 and at least one of the main housing 21 and the breast shield 23. The milk container 25 is used to collect milk in the breast of a nursing mother after expressing the milk.

[0067] Figure 2B 2 shows an exploded view of an exemplary breast pump 200 according to some aspects of the present application. Figure 2BAs shown, the breast pump 200 may further include a suction diaphragm 27 that can be detachably connected to the milk container 25. In some embodiments, the milk container 25 may include a hole portion 251, and the suction diaphragm 27 can be inserted into the hole portion 251. The suction diaphragm 27 may include a duckbill valve 221 for guiding milk into the milk container 25. The duckbill valve 221 can allow milk to be released in one direction (i.e., from the suction diaphragm 27 into the milk container 25), but not in the opposite direction. In some embodiments, the breast shield 23 may include a flange portion 273, which can be adapted to the nipple of the breast to collect milk through the path connected to the breast shield 23. The flange portion 273 can be connected to the milk container 25 and the suction diaphragm 27 through the passage 253. In some embodiments, the filter cap 28 can be further coupled to the top of the suction diaphragm 27 or the milk container 25. In some embodiments, the filter cover 28 is detachably connected to the suction diaphragm 27. The filter cover 28 can also be detachably connected to the main body housing 21. As described above, after cleaning or washing the breast pump, some liquid (such as water, milk, etc.) or moisture may remain inside the breast pump (such as remaining in the suction diaphragm 27, the hole 251, the passage 253 or other components). These liquids or moisture may damage the pump or cause the pump to malfunction. By using the filter cover 28, the liquid or moisture in the milk container 25 or the suction diaphragm 27 will be blocked by the filter cover 28, so that the liquid or moisture will not be sucked into the pump and cause damage to the pump. When the nipple of the breast is surrounded by the breast cover 23 and aligned with the flange 273, the pump in the main body discharges air from the suction diaphragm 27 through the filter cover 28, thereby generating negative pressure. Therefore, the nipple surrounded by the breast cover 23 and aligned with the flange 273 of the suction diaphragm 27 can squeeze out milk, and the milk flows into the milk container 25 through the duckbill valve 221. The duckbill valve 221 allows milk to be released in one direction (i.e., flow from the suction diaphragm 27 into the milk container 25), but not in the opposite direction. It should be noted that the filter cap 28 in this embodiment is only for illustration, but is not limited to this embodiment, and may also be provided or combined in other embodiments. For example, the filter cap 28 may be installed in a three-way pipe structure (such as Figure 2B The suction diaphragm 27 in the pump is connected to the air path of the pump (such as Figure 2E The suction hole 2115 may be located at any position between the suction hole 2115 in the pump, or may be installed between the air path connecting the pump and the pump to further prevent leakage of liquid or moisture. In some embodiments, the suction hole 2115 is located in the recessed portion of the pump.

[0068] Figure 2C 2 shows a front view of an exemplary breast pump 200 according to some aspects of the present application. Figure 2C As shown, the flange portion 273 of the breast shield body 23 is connected to the milk container 25 through the passage 253 of the milk container 25.

[0069] Figure 2D and 2E FIG. 2 shows a bottom view of a main housing 21 of an exemplary breast pump 200 according to some aspects of the present application. Figure 2D and 2E As shown, the filter cover 28 is detachably connected to the main housing 21 by one or more strip structures 2117. Among them, the strip structure 2117 firmly fixes the filter cover 28 to the main housing 21. In some embodiments, the filter cover 28 includes one or more cover openings 281. These cover openings 281 are small and narrow, and are used to block or reduce the passage of liquid or moisture while allowing air to pass through. In some embodiments, these cover openings 281 may not be aligned with the suction holes 2115 of the main housing 21; that is, the cover openings 281 are misaligned with the suction holes 2115 of the main housing 21, thereby allowing the liquid or moisture passing through the cover openings 281 to be retained in the filter cover 28 or retained between the filter cover 28 and the suction holes 2115. This can further block or reduce the leakage of liquid or moisture into the pump.

[0070] Figure 2F and 2G 2 shows a side view of a filter cap of an exemplary breast pump 200 according to some aspects of the present application. Figure 2F and 2G As shown, in some embodiments, the filter cover 28 may further include a first cover 285, which is detachably connected to the cover body 283. The first cover 285 may include a cover opening 287, which is aligned with the suction hole 2115 of the host and the cover hole 2813 on the cover body 283. In some embodiments, the cover opening 287 can be replaced by a tubular structure, thereby enabling the tubular structure to be inserted into the suction hole 2115 of the host (e.g., the recessed portion of the pump). In some embodiments, one or more concave or convex structures 2815 are connected to the cover body 283 and are arranged around the cover hole 2813 to retain liquid or moisture in the filter cover 28 (e.g., retained between the cover body 283 and the first cover 285). In some embodiments, the cover holes 281 can be arranged in one or more arrays. By forming more contact surfaces or twisted air paths throughout the air path, more liquid or moisture will be retained in the filter cover 28.

[0071] Figure 3A 2 shows a side view of an exemplary breast pump 300 according to some aspects of the present application. Figure 3AAs shown, the breast pump 300 includes a main housing 31 and one or more buttons 3111 disposed on the top of the main housing 31. The breast pump 300 may be at least partially wearable or placed in a bra. The main housing 31 may further include a power interface (not shown), which may charge the power supply of the breast pump or receive power provided by the outside of the breast pump 300 through the power interface. The main housing 31 may house the main body of the breast pump 300, including multiple components of the main body. These components may be connected to Figures 1A to 2G The components in the embodiments of breast pumps 100 and 200 shown in FIG. 1 are the same or similar.

[0072] The breast pump 300 may also include a breast shield 33 that is detachably connected to the main housing 31. In some embodiments, the breast shield 33 may be connected to the main housing 31 by, for example, fastening, snapping, locking, or mutual cooperation. When the breast shield 33 and the main housing 31 are connected to each other, the breast pump 300 may be leakproof, preventing water, moisture, and air from entering the breast pump 300. The breast shield 33 may be detachable from the main housing 31, thereby allowing the user to conveniently clean at least one of the breast shield 33 and the main housing 31. The breast shield 33 may have a concave surface on a side opposite to the main housing 31 to accommodate a breast of a nursing mother.

[0073] The breast pump 300 may further include a milk container 35. The milk container 35 is detachably connected to at least one of the main housing 31 and the breast shield 33. In some embodiments, the milk container 35 may be connected to the main housing 31 or the breast shield 33, or to both the main housing 31 and the breast shield 33, for example, by fastening, snapping, locking, or mutual cooperation. When the milk container 35 is connected to at least one of the main housing 31 and the breast shield 33, the breast pump 300 may be leakproof. When the milk container 35, the main housing 31, and the breast shield 33 are separated, the user may conveniently clean the milk container 35. In some embodiments, the milk container 35 may be detachably connected to at least one of the main housing 31 and the breast shield 33 through other components; wherein the other components are coupled between the milk container 35 and at least one of the main housing 31 and the breast shield 33. The milk container 35 is used to collect milk in the breast of a nursing mother after expressing the milk.

[0074] Figure 3B 1 shows a top view of a milk container and a breast shield of an exemplary breast pump 300 according to some aspects of the present application. Figure 3B As shown, the breast pump 300 may further include a suction diaphragm 37 detachably connected to the milk container 35. In some embodiments, the milk container 35 may include a hole portion (not shown), and the suction diaphragm 37 may be inserted into the hole portion. The suction diaphragm 37 may include a duckbill valve (not shown) for guiding milk into the milk container 35.

[0075] Figure 3C 2 shows an exploded view of an exemplary breast pump 300 according to some aspects of the present application. Figure 3C As shown, in some embodiments, the breast shield 33 may include a flange portion 333 that can be adapted to the nipple of the breast to collect milk through a path connected to the breast shield 33. The flange portion 333 can be connected to a passage of a three-way pipe structure (not shown). In some embodiments, a cover 371 can be further coupled to the top of the suction diaphragm 37. In some embodiments, the cover 371 is detachably connected to the suction diaphragm 37. The cover 371 can also be detachably connected to the milk container 35. When the nipple of the breast is surrounded by the breast shield 33 and aligned with the flange portion 333, the pump in the host exhausts air from the suction diaphragm 37 through the cover 371, thereby generating negative pressure. Therefore, the nipple surrounded by the breast shield 33 and aligned with the flange portion 333 of the suction diaphragm 37 can squeeze out milk, and the milk flows into the milk container 35 through the duckbill valve.

[0076] like Figure 3B and 3C As shown, in some embodiments, the cover 371 includes a tubular structure 373, which can be coupled to the suction hole (not shown) of the host. In some embodiments, the tubular structure 373 can extend or be coupled to another pipe to connect to the pump of the host housing 31. In some embodiments, the tubular structure 373 can be inserted into the recessed portion of the pump. In some embodiments, the cover 371 may further include a buckle 377 and an axis 375, and the buckle 377 can be used to fix the cover 371 to the suction diaphragm 37, whereby the cover 371 can be opened to expose the inner surface of the suction diaphragm 37 and the cover 371 is still connected to the suction diaphragm 37.

[0077] In some embodiments, the cover 371 further includes a raised portion 3711. The raised portion 3711 includes at least one of a concave or convex structure, a strip structure, and a raised structure formed on the inner surface of the raised portion 3711 and surrounding the opening of the tubular structure 373. These structures formed on the inner surface of the raised portion 3711 can retain some liquid (such as water, milk, etc.) or moisture inside the breast pump (such as inside the suction diaphragm 37), thereby preventing the liquid or moisture from being sucked into the pump and causing damage to the pump.

[0078] Figure 4A 4 shows a front view of an exemplary breast pump 400 according to some aspects of the present application. The main housing of the breast pump 400 is provided with a hole (e.g., similar to Figure 3CUnlike breast pump 300 (the main unit and its housing of breast pump 300 are mainly operated in a bra), the main unit and its housing of breast pump 400 can be operated outside a bra (for example, the main unit can be placed in a pocket or on a table), and a pipe or hose is used to provide negative pressure to the three-way pipe structure to squeeze out milk. Figure 4A As shown, the breast pump 400 includes a milk container 45, a suction chamber unit 49 coupled to a three-way pipe structure (not shown) of the milk container 45, a main body housing 41 coupled to the milk container 45, and a breast shield 43 coupled to the milk container 45. As described above, the main body housing 41 can be detached from the milk container 45. An additional pipe or hose (not shown) can be connected between the main body housing 41 and the milk container 45.

[0079] Figure 4B 4 shows a rear view of an exemplary breast pump 400 according to some aspects of the present application. Figure 4B As shown, the breast pump 400 further includes one or more buttons 4111 disposed on the top of the main body housing 41. In some embodiments, the button 4111 may include a power button, a switch button, or a control interface; wherein the user may start, stop or change the pumping cycle, increase or decrease the pumping pressure peak, or switch between different preprogrammed or predetermined pressure curves (e.g., to mimic a baby's sucking pattern) on the control interface. The main body housing 41 may further include a power interface (not shown), which may charge the power supply of the breast pump or receive power provided by the outside of the breast pump 400 through the power interface. The main body housing 41 may house the main body of the breast pump 400, including multiple components of the main body. These components may be connected to the main body of the breast pump 400. Figures 1A to 3C The components in the embodiments of breast pumps 100, 200 and 300 shown in FIG. 1 are the same or similar.

[0080] In some embodiments, the breast shield 43 is detachably connected to the milk container 45. In some embodiments, the breast shield 43 can be connected to the main housing 41 by, for example, fastening, snapping, locking or cooperating with each other. When the breast shield 43 and the main housing 41 are connected to each other, the breast pump 400 can be leak-proof to prevent water, moisture and air from entering the breast pump 400. The breast shield 43 can be separated from the main housing 41, thereby allowing the user to easily clean at least one of the breast shield 43 and the main housing 41. The breast shield 43 can have a concave surface on the side opposite to the main housing 41 to accommodate the breast of the nursing mother. As described above, the main housing 41 can be directly detachably connected to the milk container 45, or detachably connected to the milk container 45 through a pipe or a hose.

[0081] Figure 4C 4 shows an exploded view of an exemplary breast pump 400 according to some aspects of the present application. Figure 4C As shown, in some embodiments, the breast shield 43 may include a flange portion 433 that can be adapted to the nipple of the breast to collect milk through a path connected to the breast shield 43. The flange portion 433 can connect the milk container 45 and the three-way pipe structure 47 through the first end 4533 of the milk container 45. In some embodiments, the suction chamber unit 49 includes a suction chamber structure 491 connected to the milk container 45 through the second end 4531 of the milk container 45. The suction chamber structure 491 can be directly connected to the duckbill valve 421, or coupled to the duckbill valve 421 through a path in the milk container 45. The suction chamber structure 491 may include a suction diaphragm (not shown). When the pump applies negative pressure, the duckbill valve 421 remains closed, thereby ensuring that the negative pressure is directly applied to the milk container 45. The suction chamber unit 49 may include a suction cover 493, and the suction cover 493 is detachably connected to the suction chamber structure 491. After the suction cover 493 is connected, the suction chamber unit 49 can achieve air sealing, so that the pump can generate negative pressure on the suction diaphragm of the suction chamber structure 491, and the suction diaphragm can provide negative pressure to the nipple. In some embodiments, the main body housing 41 may further include a suction hole 411, and the suction hole 411 may be coupled to a suction tube or a suction spout 451 of the milk container 45. The suction hole 411 is connected to the pump in the main body and provides negative pressure when the pump starts a pumping operation.

[0082] Figure 4D 4 shows a perspective view of an exemplary breast pump 400 according to some aspects of the present application. Figure 4D As shown, the suction hole 411 is connected to the suction nozzle 451. The suction nozzle 451 is connected to the filter chamber 4911, and the filter chamber 4911 can prevent the liquid (such as milk or water) or moisture in the milk container 45 or the suction chamber structure 491 from leaking into the pump. When the pump starts the pumping operation, negative pressure is generated in the suction chamber structure 491, and the duckbill valve 421 remains closed, and the milk is then squeezed out and flows to the bottom of the suction chamber structure 491. After the negative pressure is released, the duckbill valve 421 is opened, and the milk flows into the milk container 45.

[0083] Figure 4E 4 shows a side view of an exemplary breast pump 400 according to some aspects of the present application. Figure 4EAs shown, the size of the filter chamber 4911 and the filter tube 4933 of the suction cover 493 is relatively small compared to the suction chamber structure 491. Therefore, when the filter tube 4933 and the filter chamber 4911 are connected, there is a filter space between the filter tube 4933 and the filter chamber 4911, thereby preventing liquid or moisture from being sucked into the pump. The suction cover 493 may further include a frame 4935. When the suction cover 493 is connected to the milk container 45, the frame 4935 fixes the suction chamber structure 491 in a fixed position. Figure 4F As shown, when the suction cap 493 is connected to the milk container 45 , the suction chamber structure 491 can be fixed between the milk container 45 and the suction cap 493 .

[0084] Figure 4G 4 shows a top view of an exemplary breast pump 400' according to some aspects of the present application, Figure 4H Shows Figure 4G 4 is a cross-sectional view of a breast pump 400' along the AA plane shown in FIG. It should be noted that the breast pump 400' is a variation of the breast pump 400 or the breast pump 100, and some components of these breast pumps may be the same or similar. In addition, components not shown in the figures illustrating the embodiment of the breast pump 400' may also be the same as the components shown in the figures illustrating the embodiment of the breast pump 400 or the breast pump 100. For example, the breast pump 400' may include a milk container 45' (corresponding to Figure 4D The suction nozzle 451' on the milk container 45 in the Figure 4D In addition, the breast pump 400' may further include a main body housing (coupled with the suction nozzle 451') Figure 4D 41 shown in FIG. 1 ). However, in Figure 4D The suction chamber structure 491 and the suction cover 493 in the embodiment of the breast pump 400 shown are Figure 4H The three-way pipe structure 47 and the suction diaphragm unit 48 in the embodiment of the breast pump 400' shown are replaced. It should also be noted that the details of the three-way pipe structure 47 and the suction diaphragm unit 48 are the same as those of the embodiment of the breast pump 400' shown. Figure 1D The details of the three-way pipe structure 17 and the suction diaphragm unit 19 in the embodiment of the breast pump 100 shown in FIG. 4 are the same or similar. Therefore, the details of the three-way pipe structure 47 and the suction diaphragm unit 48 can refer to the details of the three-way pipe structure 17 and the suction diaphragm unit 19, which will not be repeated here.

[0085] like Figure 4H As shown, Figure 1D The embodiment of the breast pump 100 shown is different in that the suction diaphragm unit 48 is embedded in the milk container 45' instead of being embedded in the main body housing. A buckle 4955 (similar to Figure 1D The breast pump 400' may further include a three-way pipe structure 47. The three-way pipe structure 47 includes a flange portion 471, which can cooperate with the nipple of the breast to collect milk through the path connected to the breast shield body 43'. The air path portion 473 is connected to the suction diaphragm unit 48 to provide suction pressure. The duckbill valve 421' is connected to the milk container 45' for guiding milk into the milk container 45'.

The flange portion 533 may be connected to the milk container 55 through a one-way valve 535 and a milk container cap 537. Each of the one-way valve 535 and the milk container cap 537 may include a threaded structure or a locking mechanism so that the one-way valve 535 and the milk container cap 537 may be fixed to the flange portion 533 and the milk container 55, respectively. In some embodiments, the one-way valve 535 may allow milk to be released in one direction (i.e., from the flange portion 533 into the milk container 55), but not in the opposite direction. It should be noted that the one-way valve 535 is not limited to the one-way valve shown in the figure, and can be any other type of valve as long as the valve can prevent backflow or function as a one-way valve. The one-way valve 535 can also be a duckbill valve disclosed in some embodiments of the present application.

[0088] In some embodiments, the breast pump 500 may further include a suction diaphragm unit 595, and the suction diaphragm unit 595 is coupled to the second side of the second housing 54 through the suction portion 591 of the second housing 54. A suction channel 593 is provided between the suction portion 591 and the flange portion 533 so as to apply negative pressure to the nipple of the breast to express milk. In some embodiments, the suction diaphragm unit 595 is connected to the suction cover 5513 and the suction tube 5511 through the socket 523. For example, the suction cover 5513 and the suction tube 5511 may be directly installed in the suction diaphragm unit 595 through the socket 523, or installed in the suction diaphragm unit 595 through an additional pipeline (not shown) formed between the suction cover 5513 and the suction tube 5511 and the suction diaphragm unit 595.

[0089] Figure 5C FIG. 4 shows a front view of the second housing 54 of an exemplary breast pump 500 according to some aspects of the present application. Figure 5C As shown, the suction diaphragm unit 595 is coupled to the suction portion 591. The suction diaphragm unit 595 may include a suction diaphragm frame 5951 and one or more sealing portions 5953, and the suction diaphragm frame 5951 and the one or more sealing portions 5953 are both used to fix a suction diaphragm (not shown) to a fixed position. The suction diaphragm unit 595 is provided with a contact protrusion 5957 for contacting and positioning the suction diaphragm. One or more rib structures 5955 are provided in the suction diaphragm unit 595 for supporting the suction diaphragm unit 595 to resist the negative pressure applied thereto.

[0090] Figure 5D FIG. 5 shows another front view of the second housing 54 of an exemplary breast pump 500 according to some aspects of the present application. Figure 5D As shown, the suction diaphragm unit 595 may further include a suction hole 5952 connected to the suction channel 593. One or more exhaust grooves 5958 may also be provided to exhaust the air in the pressure chamber of the suction diaphragm unit 595.

[0091] Figure 5E A side view of the second housing 54 of an exemplary breast pump 500 according to some aspects of the present application is further shown. Figure 5E As shown, the suction channel 593 is located between the suction portion 591 and the flange portion 533. The one-way valve 535 is coupled to the flange portion 533. A milk exhaust port 551 is provided for air to be exhausted so that milk can smoothly flow into the milk container 55 through the one-way valve 535 (i.e., when air is exhausted from the milk container, milk can flow into the milk container without generating bubbles or overflowing). Fig. 5F shows a side view of a suction diaphragm unit 595 including a suction diaphragm, Figure 5G A side view of a one-way valve 535 including a valve 5351 of the one-way valve 535 is shown.

[0092] Figure 5H FIG. 5 shows a rear view of the first housing 52 of an exemplary breast pump 500 according to some aspects of the present application. As described above, the suction cover 5513 and the suction tube 5511 are coupled to the suction diaphragm unit 595 via the socket 523. The suction cover 5513 and the suction tube 5511 are installed from the first side of the first housing 52 via the socket 523. Figure 5H As shown, the first housing 52 may include one or more diaphragm fixings (e.g., an inner diaphragm fixing 5251 and an outer diaphragm fixing 5253), wherein the suction cover 5513 and the suction tube 5511 are connected to each other through the socket 523 in the diaphragm fixing. These diaphragm fixings are used to fix and position the suction diaphragm from the middle to the periphery of the suction diaphragm. One or more exhaust guides 5254 may also be provided around the inner diaphragm fixing 5251 and the outer diaphragm fixing 5253 for releasing air or negative pressure before or after the suction diaphragm is installed. In some embodiments, the suction cover 5513 may also include a suction nozzle 5252, and the suction nozzle 5252 is detachably connected to the suction hole 5952. Fig.5I It is a side view of the first housing 52 to show that the inner diaphragm fixing part 5251 protrudes more than the outer diaphragm fixing part 5253, so that the suction diaphragm can be fixed from the middle to the outer periphery of the suction diaphragm.

[0093] Figure 5J Further illustrating a front view of a first housing 52 of an exemplary breast pump 500 according to some aspects of the present application, Figure 5K FIG. 5 shows a cross-sectional view of an exemplary breast pump 500 along the BB plane according to some aspects of the present application. Figure 5K As shown, the suction diaphragm 5954 is located on the inner surface of the suction diaphragm unit 595. When the nipple of the breast is inserted into the flange portion 533 of the breast shield body 54 and the pump starts to generate negative pressure through the suction tube 5511, the suction diaphragm 5954 of the suction diaphragm unit 595 starts to contract, so that the negative pressure starts to be applied to the nipple through the suction channel 593, thereby squeezing out milk. Then, the milk flows into the milk container 55 through the one-way valve 535. In some embodiments, as Figure 5K and Figure 5L As shown in the enlarged view in FIG. 5 , the milk container 55 may further include a milk vent 551 (for example, the milk vent 551 may be provided on the milk container cover 538) for allowing air to be discharged so that milk can smoothly flow into the milk container 55 through the one-way valve 535. In some embodiments, the one-way valve 535 may further include a sealing line 5353 located between the milk container cover 537 of the milk container 55 and the one-way valve 535 to prevent milk from leaking from the milk container 55 through the interface between the milk container 55 and the one-way valve 535.

In some embodiments, according to the embodiments of the present application, the breast pumping system 600 is at least partially embedded in or coupled to the host. For example, the breast pumping system 600 can be embedded in the host, and the host is coupled to the host housing 11, 21, 31 or 41. However, the host is not limited to the embodiments of the present application, and can be any host connected to a breast pump, or any host at least partially located in a breast pump, wherein the breast pump can be any of the breast pumps 100, 200, 300, 400, 400' or 500 described above. Figure 6 As shown, the breast pump system 600 may include a microprocessor 611. The microprocessor 611 includes a controller 613 and an address register 615 and a memory 617 coupled to the controller 613. A pump 601 and a solenoid valve 603 are provided for generating negative pressure for any breast pump 100, 200, 300, 400, 400' or 500 as described above. The microprocessor 611 is used to control the operation of the pump 601 and the solenoid valve 603 to perform all functions of the pump and the solenoid valve, including starting, stopping or changing the pumping cycle, increasing or decreasing each pumping pressure peak, or switching between different pre-programmed or predetermined pressure curves (e.g., to mimic the sucking pattern of a baby).
