Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products technology, and more specifically, to a wearable breast pump that can be used while lying down. Background Technology

[0002] Wearable breast pumps are breast pumps that can be fixed to the breast, offering good portability and privacy. However, existing Chinese patents, such as CN219878808U, have limitations in their use. When the user is lying down, milk may flow back down due to gravity and leak from the gaps between the pump and the body, limiting its application scenarios, resulting in poor performance and a negative user experience. Furthermore, some existing wearable breast pumps have the start switch and suction adjustment buttons located on the pump itself, requiring users to reach into their clothing to find the buttons, which is inconvenient and unsuitable for use in public places. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a wearable breast pump that can be used while lying down, including a milk storage component, a bra assembly, and a drive assembly. The milk storage component and the bra assembly overlap to form a milk storage chamber. The bra assembly includes a bra with an anti-backflow device. The anti-backflow device has a resiliently opening and closing negative pressure port, which is connected to the milk storage chamber. The drive assembly connects to the negative pressure port and provides suction. When the drive assembly provides suction, the negative pressure port opens to draw milk into the milk storage chamber. When the drive assembly stops suction, the negative pressure port closes to prevent milk backflow.

[0004] Optionally, the bra includes an outer ring portion, which is flared and adapted to contact the breast. The flared portion has a first opening in the center, and the anti-backflow device is installed in the first opening and seals against the inner wall of the first opening.

[0005] Optionally, the bra includes an inner ring portion, the bottom of which is provided with a second opening communicating with the milk storage chamber. The first opening communicates with the milk storage chamber through the second opening. A one-way valve is installed on the second opening, and the one-way valve guides the milk at the negative pressure port into the milk storage chamber.

[0006] Optionally, the milk storage assembly includes a milk storage bowl, the milk storage cavity is formed by the milk storage bowl and the bra covering each other, the milk storage bowl is provided with a connecting post, the inner ring is fitted on the connecting post and forms an air cavity between the inner ring and the connecting post, the drive assembly connects to the air cavity and provides suction to the air cavity, and the air cavity is simultaneously connected to the negative pressure port and the one-way valve.

[0007] Optionally, the anti-backflow device is at least partially housed in the air cavity, and the anti-backflow device is funnel-shaped and adapted to accommodate the head of the breast.

[0008] Optionally, the side wall of the milk storage chamber is provided with a pressure balancing device, and the pressure balancing device is provided with a vent that can be opened and closed flexibly. The vent is used to discharge the gas in the milk storage chamber to balance the pressure.

[0009] Optionally, the milk storage chamber has a connection port on its side wall, and the air pressure balancing device has a connection part. The connection part has a protruding elastic retaining ring. After the connection part is inserted into the connection port, the elastic retaining ring is sealed and engaged with the connection port.

[0010] Optionally, the air pressure balancing device is located at the upper part of the milk storage chamber at the end away from the bra. Both the anti-backflow device and the air pressure balancing device are made of soft rubber. The anti-backflow device and the bra are detachably connected, and the air pressure balancing device and the side wall of the milk storage chamber are detachably connected.

[0011] Optionally, it also includes a remote control, which has a circuit board inside. The circuit board is wirelessly connected to the drive component, and the remote control is used to control the start and stop of the drive component and the suction force.

[0012] Optionally, the remote control is provided with a button and a tactile switch. The button is adapted to press the tactile switch, and the tactile switch is electrically connected to the circuit board. When the button is pressed for a short time, the tactile switch controls the start and stop of the drive component through the circuit board. When the button is pressed for a long time, the tactile switch controls the suction force of the drive component through the circuit board.

[0013] Compared to existing technologies, the wearable breast pump of this invention, which can be used while lying down, incorporates an anti-backflow device on the bra. This device allows the negative pressure port to open and close elastically under air pressure. When the drive unit is working, the negative pressure port opens, allowing milk to flow into the milk storage chamber through suction. When the suction stops, the negative pressure port closes to prevent milk backflow. This allows users to use the wearable breast pump while lying down without worrying about milk backflow staining their clothes, resulting in better performance and a more comfortable user experience.

[0014] Meanwhile, an air pressure balancing device is installed on the side wall of the milk storage chamber. The air pressure in the milk storage chamber is balanced by the flexible vent holes on the air pressure balancing device. Since the air pressure balancing device is located far away from the bra and at the top, when the vent holes are open to allow air to pass through, the liquid milk does not easily reach the location of the air pressure balancing device. Therefore, the vent holes only allow gas to pass through and not liquid to pass through, so that the milk does not flow out while balancing the air pressure in the milk storage chamber.

[0015] Furthermore, the wireless remote control allows users to operate the drive unit without having to reach into their clothing to turn it on. Additionally, the remote control's buttons and touch switches allow users to control the drive unit's start / stop and suction power simply by pressing the buttons, making it simple, convenient, and easy to use.

[0023] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0024] The accompanying drawings of the embodiments of this utility model provide a coordinate system XY, where the positive direction of the X-axis represents the front, the negative direction of the X-axis represents the rear, the positive direction of the Y-axis represents the top, and the negative direction of the Y-axis represents the bottom.

[0025] This utility model embodiment provides a wearable breast pump that can be used while lying down, combined with Figures 1 to 5As shown, the device includes a milk storage assembly 1, a breast shield assembly 2, and a drive assembly 3. The milk storage assembly 1 and the breast shield assembly 2 are combined to form a milk storage chamber 4. The breast shield assembly 2 includes a breast shield 21, which is equipped with an anti-backflow device 22. The anti-backflow device 22 is equipped with a negative pressure port 221 that can be elastically opened and closed. The negative pressure port 221 is adapted to communicate with the milk storage chamber 4. The drive assembly 3 is connected to the negative pressure port 221 and provides suction. When the drive assembly 3 provides suction, the negative pressure port 221 opens to draw milk into the milk storage chamber 4. When the drive assembly 3 stops suction, the negative pressure port 221 closes to prevent milk backflow.

[0026] In this embodiment, the method by which the driving component 3 generates suction is the prior art and will not be described in detail here.

[0027] like Figures 1 to 3 As shown, optionally, the bra 21 includes an outer ring portion 211, which is flared and adapted to contact the breast. The outer ring portion 211 has a first opening in the middle of the flared opening, and the anti-backflow device 22 is installed in the first opening and seals against the inner wall of the first opening.

[0028] In this embodiment, the milk storage bowl 11 and the bra 21 are detachably connected, and the bra 21 and the anti-backflow device 22 are detachably connected. Both the bra 21 and the anti-backflow device 22 are made of soft rubber. The soft rubber material is preferably food-grade silicone. This material makes the breast more comfortable to the touch, and also has excellent sealing performance, maintaining a tighter fit between the breast and the bra 21 to prevent air leakage and milk backflow. Furthermore, it has good tensile strength, exhibiting good deformation resistance during milk expression or when the bra 21 is removed, making it less prone to damage. It is also non-toxic, odorless, and has good resistance to high and low temperatures and aging.

[0029] like Figure 2 As shown, optionally, the bra 21 includes an inner ring portion 212, the bottom of which is provided with a second opening that communicates with the milk storage chamber 4. The first opening communicates with the milk storage chamber 4 through the second opening. A one-way valve 23 is installed on the second opening, and the one-way valve 23 guides the milk at the negative pressure port 221 into the milk storage chamber 4.

[0030] like Figure 2 Taking the direction shown as an example, in this embodiment, the first opening is located in the front-to-back direction, and the second opening is located in the up-down direction. The bra 21 is integrally formed. Milk enters the one-way valve 23 from the second opening and then enters the milk storage chamber 4 through the one-way valve 23. The one-way valve 23 can prevent milk from flowing back into the milk storage chamber 4, and has a good sealing effect. Furthermore, the one-way valve 23 and the second opening are detachably connected to facilitate cleaning after disassembly.

[0031] like Figure 2 As shown, optionally, the milk storage assembly 1 includes a milk storage bowl 11, and the milk storage chamber 4 is formed by the milk storage bowl 11 and the breast shield 21 covering each other. The milk storage bowl 11 is provided with a connecting post 111, and the inner ring portion 212 is sleeved on the connecting post 111 and forms an air chamber 112 between the inner ring portion 212 and the connecting post 111. The driving assembly 3 communicates with the air chamber 112 and provides suction to the air chamber 112. The air chamber 112 is also connected to the negative pressure port 221 and the one-way valve 23.

[0032] The connecting post 111 is located on the inner wall of the milk storage bowl 11 at the end away from the breast shield 21, making the structure of the breast pump more compact in the front-to-back direction. The connecting post 111 and the milk storage bowl 11 are integrally formed. The connecting post 111 and the inner ring 212 are sealed to each other, ensuring the air chamber 112 is airtight and making the milk expression effect better.

[0033] Optionally, the anti-backflow device 22 is at least partially housed in the air cavity 112, and the anti-backflow device 22 is funnel-shaped and adapted to accommodate the head of the breast.

[0034] like Figure 1 and 2 As shown, in this embodiment, the horn sidewall of the anti-backflow device 22 and the horn sidewall of the bra 21 are attached to each other. The negative pressure port 221 is located at one end of the anti-backflow device 22 near the milk storage bowl 11, and the part of the anti-backflow device 22 near the milk storage bowl 11 is accommodated in the air chamber 112 to reduce the space occupied, make the structure more compact, and make it easier for users to wear it more discreetly.

[0035] like Figure 4 As shown, optionally, the side wall of the milk storage chamber 4 is provided with a pressure balancing device 12, and the pressure balancing device 12 is provided with a vent 121 that can be opened and closed elastically. The vent 121 is used to discharge the gas in the milk storage chamber 4 to balance the pressure.

[0036] When the air pressure inside the milk storage chamber 4 is unbalanced, the vent 121 opens to exchange gas with the outside to balance the air pressure. When the air pressure inside the milk storage chamber 4 is balanced, the vent 121 remains closed and sealed.

[0037] like Figure 4 As shown, optionally, the milk storage chamber 4 has a connection port on its side wall, and the air pressure balancing device 12 has a connection part 122. The connection part 122 has a protruding elastic retaining ring 123. After the connection part 122 is inserted into the connection port, the elastic retaining ring 123 is sealed and engaged with the connection port.

[0038] like Figure 2As shown, optionally, the air pressure balancing device 12 is located at the upper part of the milk storage chamber 4 away from the bra 21. Both the anti-backflow device 22 and the air pressure balancing device 12 are made of soft rubber. The anti-backflow device 22 and the bra 21 are detachably connected. The air pressure balancing device 12 and the side wall of the milk storage chamber 4 are detachably connected.

[0039] Wearable breast pumps typically present the following issues during use: Figure 2 As shown, when used in the vertical direction, the drive component 3 faces upward. In this usage state, the milk in the milk storage chamber 4 gathers at the bottom under the action of gravity, so the milk is not easy to come into contact with the air pressure balance device 12 located above. At this time, even if the vent 121 is opened to allow air to pass through, the milk is not easy to flow out from the vent 121.

[0040] When the user is lying flat (see reference as follows) Figure 2 When rotated 90 degrees clockwise, under the influence of gravity, the milk gathers at the end near the bra 21, while the pressure balancing device 12 is far away from the bra 21. Therefore, the milk is not easy to come into contact with the pressure balancing device 12. Even if the vent 121 is open for ventilation, the milk is not easy to flow out from the vent 121.

[0041] like Figure 4 As shown, in this embodiment, the soft rubber material is preferably food-grade silicone, and the air pressure balancing device 12 is integrally molded. The connection port is located on the milk storage bowl 11. When the air pressure balancing device 12 is installed in the connection port, the elastic retaining ring 123 abuts against the inner wall of the storage bowl, forming a seal with the connection port. The air pressure balancing device 12 also has an extension 124, which abuts against the outer wall of the milk storage bowl 11. The user can pinch the extension 124 to pull out the air pressure balancing device 12 for cleaning.

[0042] like Figure 5 As shown, optionally, it also includes a remote controller 5, which has a circuit board 51 inside. The circuit board 51 is wirelessly connected to the drive component 3. The remote controller 5 is used to control the start and stop of the drive component 3 and the suction force.

[0043] Optionally, the remote control 5 is provided with a button 52 and a tactile switch 53. The button 52 is adapted to press the tactile switch 53, and the tactile switch 53 is electrically connected to the circuit board 51. When the button 52 is pressed for a short time, the tactile switch 53 controls the start and stop of the drive component 3 through the circuit board 51. When the button 52 is pressed for a long time, the tactile switch 53 controls the suction force of the drive component 3 through the circuit board 51.

[0044] Furthermore, the program built into circuit board 5151 can remember the suction level previously selected by the user. When the user presses button 5252 for a short time, the drive component 33 outputs the same suction level as before; when the user presses button 5252 for a long time, the drive component 33 starts to adjust the suction level. Compared to the existing technology that adjusts the suction level by detecting the pressure of the user pressing button 52, this setting is more labor-saving for users who need to rest after production by detecting the pressing time. Moreover, compared to the existing technology that uses multiple buttons 52 for start / stop and level adjustment, single button 52 control is not only convenient to operate, eliminating the need to look up and select different buttons 52, but also saves costs, reduces the size of the remote control 5, and makes it easier for users to carry.

[0045] like Figure 5 As shown, in this embodiment, the remote control 5 also includes a housing 54, an upper inner cover 55, a lower inner cover 56, and a bracket 57. The remote control 5 is elliptical, and the button 52 is made of soft rubber with a recessed pressing part for easy finger placement. The bracket 57 and the button 52 are inserted and fixed together. The bottom of the bracket 57 has a protruding pressing post suitable for pressing the tactile switch 53. The button 52 is mounted on the housing 54, and the circuit board 51 is accommodated in the lower inner cover 56 and snapped together with it. The upper inner cover 55 and the lower inner cover 56 are connected by a snap-fit, and both the upper inner cover 55 and the lower inner cover 56 are accommodated in the housing 54.

[0046] Compared to existing technologies, the wearable breast pump of this invention, which can be used while lying down, features an anti-backflow device 22 on the bra 21. This device allows the negative pressure port 221 on the anti-backflow device 22 to open and close elastically under air pressure. When the drive assembly 3 is working, the negative pressure port 221 opens, allowing milk to flow into the milk storage chamber 4 through suction. When the suction stops, the negative pressure port 221 closes to prevent milk backflow. This allows users to use the wearable breast pump while lying down without worrying about milk backflow staining their clothes, resulting in better performance and a more comfortable user experience.

[0047] Meanwhile, an air pressure balancing device 12 is installed on the side wall of the milk storage chamber 4. The air pressure in the milk storage chamber 4 is balanced by the air vent 121 on the air pressure balancing device 12, which can be opened and closed elastically. Since the air pressure balancing device 12 is located far away from the bra 21 and at the top, when the air vent 121 is open to allow air to pass through, the liquid milk is not easy to reach the location of the air pressure balancing device 12. Therefore, the air vent 121 only allows gas to pass through and not liquid to pass through, so that the milk does not flow out while balancing the air pressure in the milk storage chamber 4.

[0048] Furthermore, the remote control 5 is set to wireless connection, so users do not need to put their hands into the clothes to turn on the drive component 3. They can control the drive component 3 to work through the remote control 5. At the same time, by using the button 52 and the touch switch 53 on the remote control 5, users only need to control the time of pressing the button 52 to control the start and stop of the drive component 3 and the output suction power, which is simple, convenient and easy to operate.
