Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a dual-sided electric breast pump. Background Technology

[0002] A breast pump is a maternal and infant product used to express breast milk. When an infant is unable to suckle directly, a breast pump can be used to express breast milk to ensure breastfeeding. Existing electric breast pumps use a pump or motor to generate negative pressure for suction, with the suction force indirectly acting on the breast. Currently, some electric breast pumps on the market have the problem of only being able to pump from one breast or both breasts simultaneously. Single-sided pumping is inefficient, and simultaneous pumping from both breasts requires the user to manually switch tubes. Furthermore, when using a single pump, simultaneous pumping from both breasts significantly reduces suction power, resulting in poor milk expression. For example, Chinese patent CN204033880U discloses a breast pump including a bottle and a pump body. The pump body includes a connector connected to the bottle opening, a negative pressure mechanism on top of the connector, and a milk extraction section on top of the connector, tilted out from one side of the negative pressure mechanism. It is clear that this breast pump can only pump from one breast, resulting in low milk expression efficiency. Utility Model Content

[0003] In view of the above-mentioned technical problems existing in the prior art, this utility model provides a dual-sided electric breast pump. By using a control component, the first and second electric control valves can be opened and closed alternately in sequence to realize the alternating milk expression of both breasts, effectively reducing the time required for milk expression and improving the convenience and flexibility of using the dual-sided electric breast pump.

[0004] This application provides a dual-sided electric breast pump. The dual-sided electric breast pump includes a milk collection assembly, a main unit, and a control assembly. The milk collection assembly includes a first air tube group and a second air tube group that are independently arranged. The first air tube group is connected to one breast, and the second air tube group is connected to the other breast. The main unit includes a housing and a suction pump assembly and an electrically controlled valve assembly disposed within the housing. The suction pump assembly has a first suction port and a second suction port. The electrically controlled valve assembly includes a first electrically controlled valve and a second electrically controlled valve. Both the first and second electrically controlled valves have an inlet and an outlet. The inlet of the first electrically controlled valve is connected to the first air tube group, and the inlet of the second electrically controlled valve is connected to the second air tube group. The outlet of the first electrically controlled valve is connected to the first suction port, and the outlet of the second electrically controlled valve is connected to the second suction port. Both the first and second electrically controlled valves have an open state where their respective inlets and outlets are connected, and a closed state where their respective inlets and outlets are isolated. The control component is located inside the housing and is electrically connected to the air pump assembly, the first solenoid valve, and the second solenoid valve, respectively. The control component is used to control the air pump assembly to turn on and to control the first solenoid valve and the second solenoid valve to alternately be in the open state so as to alternately suck milk through the first air tube group and the second air tube group.

[0005] For example, both the first and second electrically controlled valves also have an atmospheric communication port, which communicates with the external atmosphere. When the first and second electrically controlled valves are in the closed state, the atmospheric communication port is connected to the air inlet. This allows for pressure balancing between the emulsion collection assembly and the external environment without the need for additional devices.

[0006] For example, both the first and second electrically controlled valves have movable barrier members in their valve chambers. The barrier members are used to connect the air inlet and the air outlet under the control of the control component, or to connect the atmospheric communication hole with the air inlet, so as to effectively ensure the switching efficiency of the electrically controlled valve group.

[0007] For example, the housing is further provided with an adapter, which has a first cavity and a second cavity that are independently arranged. The air inlet of the first electrically controlled valve is connected to the first air pipe group through the first cavity, and the air inlet of the second electrically controlled valve is connected to the second air pipe group through the second cavity. The adapter can limit the distance between the first air pipe group and the second air pipe group, so as to ensure the stability of the relative positional relationship between the first air pipe group and the second air pipe group.

[0008] For example, the adapter is made of an elastomeric material, which can have good shock absorption properties, thereby absorbing and buffering the vibrations generated by the air pump assembly during operation.

[0009] For example, the air pump assembly includes a pump body and a T-shaped connector. One side of the T-shaped connector is connected to the gas inlet of the pump body, and the first air inlet and the second air inlet are both formed on the other side of the T-shaped connector, so as to simplify the connection structure of the dual-sided electric breast pump and reduce the manufacturing cost and assembly difficulty of the dual-sided electric breast pump.

[0010] For example, the main unit also includes a rechargeable battery and a charging interface disposed within the housing. The rechargeable battery, the charging interface, and the control component are electrically connected to each other to power the control component via the rechargeable battery and / or the charging interface, so that the dual-sided electric breast pump can meet different usage scenarios and conditions, thereby improving the practicality of the dual-sided electric breast pump.

[0011] For example, the upper surface of the housing is provided with a display panel, which is electrically connected to the control component and is used to display the working status of the dual-sided electric breast pump. The working status of the dual-sided electric breast pump can be intuitively understood through the display panel, which greatly facilitates the use of the user.

[0012] For example, the air inlet of the first electrically controlled valve is directly connected to the first air tube assembly, the air inlet of the second electrically controlled valve is directly connected to the second air tube assembly, the air outlet of the first electrically controlled valve is directly connected to the first suction port, and the air outlet of the second electrically controlled valve is directly connected to the second suction port. This not only ensures the tightness between the interfaces and avoids air leakage, but also simplifies the connection method of the dual-sided electric breast pump.

[0013] For example, the housing is provided with a first through hole and a second through hole. The first through hole is correspondingly arranged with the first cavity of the adapter, and the second through hole is correspondingly arranged with the second cavity of the adapter, so as to avoid the situation where the interfaces fall off under the action of external force, and effectively ensure the practicality and reliability of the dual-sided electric breast pump.

[0014] Compared with the prior art, the beneficial effects of this utility model embodiment are as follows: The air pump assembly of this utility model can be connected to one breast through the first air tube assembly and the first electric control valve, and can be connected to the other breast through the second air tube assembly and the second electric control valve. In this way, by using the control assembly to control the alternating opening and closing of the first and second electric control valves in sequence, alternating milk expression of both breasts can be achieved. This effectively ensures that the suction force provided by the air pump assembly is concentrated on one side of the two breasts, rather than dispersing the suction force to simultaneously express milk from both breasts, thus achieving sufficient suction and better milk expression effect. Moreover, compared with the ability to express milk from only one side, the above-mentioned dual-sided electric breast pump can effectively reduce the time required for milk expression, and improve the convenience and flexibility of using the dual-sided electric breast pump.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0024] This application provides a dual-sided electric breast pump. For example... Figures 1 to 3As shown, the dual-sided electric breast pump includes a milk collection assembly 1, a main unit 2, and a control assembly 5. The milk collection assembly 1 includes a first airway group 11 and a second airway group 12, which are independently arranged. The first airway group 11 is connected to one breast, and the second airway group 12 is connected to the other breast. The main unit 2 includes a housing 21 and an air pump assembly 3 and an electrically controlled valve assembly 4 disposed within the housing 21. The air pump assembly 3 has a first air intake port 31 and a second air intake port 32. The electrically controlled valve assembly 4 includes a first electrically controlled valve 41 and a second electrically controlled valve 42. Both the first electrically controlled valve 41 and the second electrically controlled valve 42 have an air inlet 43 and an air outlet 44. The air inlet 43 of the first electrically controlled valve 41 is connected to the first air pipe assembly 11, and the air inlet 43 of the second electrically controlled valve 42 is connected to the second air pipe assembly 12. The air outlet 44 of the first electrically controlled valve 41 is connected to the first air intake port 31, and the air outlet 44 of the second electrically controlled valve 42 is connected to the second air intake port 32. Both the first electrically controlled valve 41 and the second electrically controlled valve 42 have an open state in which their respective air inlets 43 and air outlets 44 are connected, and a closed state in which their respective air inlets 43 and air outlets 44 are isolated. The control component 5 is located inside the housing 21 and is electrically connected to the air pump assembly 3, the first solenoid valve 41 and the second solenoid valve 42 respectively. The control component 5 is used to control the air pump assembly 3 to open and to control the first solenoid valve 41 and the second solenoid valve 42 to alternately be in the open state so as to alternately suck milk through the first air tube group 11 and the second air tube group 12.

[0025] like Figure 1 and Figure 2 As shown, the aforementioned housing 21 may include an outer shell 211 and a bottom shell 212. The outer shell 211 and the bottom shell 212 can enclose a receiving space 213 for housing the air pump assembly 3 and the electronically controlled valve assembly 4. The outer shell 211 and the bottom shell 212 can be detachably connected, such as by screws or snap-fit ​​connections, etc., and this application does not specifically limit this. The aforementioned housing 21 can provide protection for the air pump assembly 3 and the electronically controlled valve assembly 4 located therein, preventing damage to the air pump assembly 3 and the electronically controlled valve assembly 4 when subjected to external forces.

[0026] The first tracheal tube assembly 11 and the second tracheal tube assembly 12 described above may each have a tube body and interfaces located at both ends of the tube body. The interface at one end of the tube body can be connected to the main unit 2, and the interface at the other end of the tube body can be connected to the breast through other structural components of the breast milk collection assembly 1, such as through the negative pressure chamber 13 described below. The tube body may be made of flexible material to improve its adaptability, allowing it to deform and improve ease of use and storage.

[0027] The aforementioned milk collection assembly 1 may further include a negative pressure chamber 13 and a diaphragm 14 located within the negative pressure chamber 13. The diaphragm 14 may be made of an elastic material. When the air pump assembly 3 draws gas from the negative pressure chamber 13, the diaphragm 14 can undergo elastic deformation within the negative pressure chamber 13, thereby generating negative pressure within the negative pressure chamber 13 to achieve the milk suction operation of the milk collection assembly 1. When the negative pressure within the negative pressure chamber 13 is released, the diaphragm 14 will restore its elastic deformation, at which point the milk collection assembly 1 stops the milk suction operation. Specifically, as shown... Figure 3 As shown, Figure 3 Two negative pressure chambers 13 are arranged side by side in the figure. The negative pressure chamber 13 located on the left side of the figure is in a negative pressure state. The diaphragm 14 in the negative pressure chamber 13 undergoes elastic deformation. At this time, the milk collection assembly 1 performs milk suction operation through the first tracheal tube group 11. The negative pressure chamber 13 located on the right side of the figure is in a depressurized state. The diaphragm 14 in the negative pressure chamber 13 restores its elastic deformation. At this time, the milk collection assembly 1 stops milk suction operation through the second tracheal tube group 12.

[0028] The first and second electrically controlled valves 41 and 42 can be alternately opened under the control of the control component 5. Specifically, the first and second electrically controlled valves 41 and 42 can be opened in turn according to a certain sequence or time pattern during operation. Specifically, when the first electrically controlled valve 41 is open, the second electrically controlled valve 42 is closed; when the second electrically controlled valve 42 is open, the first electrically controlled valve 41 is closed. It can be understood that the suction pump assembly 3 can be in a continuous working state. By controlling the alternating opening and closing of the first and second electrically controlled valves 41 and 42, the alternating milk expression of the dual-sided electric breast pump can be achieved, ensuring that one side of the breast is continuously pumped by the suction pump assembly 3, and avoiding frequent opening and closing of the suction pump assembly 3, effectively improving the service life of the suction pump assembly 3.

[0029] It should be noted that the control component 5 can be constructed using electronic components such as timers, comparators, registers, and digital logic circuits, or implemented using processor chips such as microcontrollers, microprocessors, programmable logic controllers (PLCs), digital signal processors (DSPs), field-programmable gate arrays (FPGAs), programmable logic arrays (PLAs), and application-specific integrated circuits (ASICs) and their peripheral circuits.

[0030] It is understood that the aforementioned dual-sided electric breast pump can be used for unilateral breast pumping as needed. For example, the control component 5 can control the first electric valve 41 to remain open and the second electric valve 42 to remain closed, so as to perform unilateral breast pumping through the first air tube assembly 11.

[0031] The air pump assembly 3 of this invention can be connected to one breast through the first air tube assembly 11 and the first electric control valve 41, and can be connected to the other breast through the second air tube assembly 12 and the second electric control valve 42. In this way, by using the control assembly 5 to control the alternating opening and closing of the first electric control valve 41 and the second electric control valve 42 in sequence, it is possible to achieve alternating milk pumping of both breasts. This effectively ensures that the suction force provided by the air pump assembly 3 is concentrated on one side of the breast, rather than dispersing the suction force to pump both breasts at the same time, so as to achieve sufficient suction and better milk pumping effect. Moreover, compared with the ability to pump milk from only one side, the above-mentioned dual-sided electric breast pump can effectively reduce the time required for milk pumping, and improve the convenience and flexibility of using the dual-sided electric breast pump.

[0032] In some embodiments, such as Figure 4 and Figure 5 As shown, the first solenoid valve 41 and the second solenoid valve 42 also have an atmospheric communication hole 45, which is connected to the external atmosphere. When the first solenoid valve 41 and the second solenoid valve 42 are in the closed state, the atmospheric communication hole 45 is connected to the air inlet 43.

[0033] In the above embodiment, when the first electric control valve 41 and the second electric control valve 42 are in the closed state, air can be drawn in through the atmospheric communication hole 45. In this way, without the need for other additional devices, the pressure between the milk collection component 1 and the external environment can be balanced, thereby stopping the milk collection component 1 from milking operation. While ensuring that the dual electric breast pumps can alternately pump milk, the mechanical structure of the electric control valve group 4 is also effectively simplified.

[0034] The aforementioned atmospheric communication hole 45 can be formed on the first solenoid valve 41 and the second solenoid valve 42 respectively. When the first solenoid valve 41 and the second solenoid valve 42 are in the closed state, the negative pressure in the negative pressure chamber 13 can draw air into the negative pressure chamber 13 through the atmospheric communication hole 45 and the air inlet 43, thereby balancing the air pressure in the negative pressure chamber 13 with the atmospheric air pressure, thereby restoring the elastic deformation of the diaphragm 14 and stopping the milk collection component 1 from milk suction operation.

[0035] In some embodiments, such as Figure 5 As shown, both the first solenoid valve 41 and the second solenoid valve 42 are provided with movable barrier members 46 in their valve chambers. The barrier members 46 are used to connect the air inlet 43 and the air outlet 44 under the control of the control component 5, or to connect the atmospheric communication hole 45 with the air inlet 43.

[0036] In the above embodiments, the control component 5 can control the opening or closing of the first solenoid valve 41 and the second solenoid valve 42 by controlling the movement of the blocking member 46. In this way, while simplifying the mechanical structure of the first solenoid valve 41 and the second solenoid valve 42, the switching efficiency of the solenoid valve group 4 is also effectively guaranteed.

[0037] The shape of the aforementioned barrier 46 can be adapted to the inner contour of the valve cavity. When the barrier 46 slides in the valve cavity, the barrier 46 can open or block the passage between the air inlet 43 and the air outlet 44, or open or block the passage between the atmospheric communication hole 45 and the air outlet 44.

[0038] When the first and second solenoid valves 41 and 42 are open, the control component 5 can control the blocking element 46 to move towards the atmospheric connection hole 45 until the atmospheric connection hole 45 is sealed. In this way, the air pump assembly 3 can draw gas from the negative pressure chamber 13 through the air inlet 43 and the air outlet 44. Conversely, when the first and second solenoid valves 41 and 42 are closed, the control component 5 can control the blocking element 46 to move away from the atmospheric connection hole 45. In this way, air can flow into the negative pressure chamber 13 through the atmospheric connection hole 45 and the air inlet 43 to ensure the air pressure balance between the negative pressure chamber 13 and the external environment.

[0039] In some embodiments, such as Figures 1 to 3 As shown, the housing 21 is also provided with an adapter 22. The adapter 22 has a first cavity 23 and a second cavity 24 that are independently arranged. The air inlet 43 of the first solenoid valve 41 is connected to the first air pipe group 11 through the first cavity 23, and the air inlet 43 of the second solenoid valve 42 is connected to the second air pipe group 12 through the second cavity 24.

[0040] In the above embodiment, the milk collection assembly 1 and the electronically controlled valve assembly 4 can be connected by the adapter 22. The adapter 22 can limit the distance between the first air tube assembly 11 and the second air tube assembly 12, ensuring the stability of the relative positional relationship between the first air tube assembly 11 and the second air tube assembly 12. This avoids the first air tube assembly 11 and the second air tube assembly 12 from getting tangled together during the milk pumping operation, which would affect the use of the dual-sided electric breast pump. This effectively improves the practicality and reliability of the dual-sided electric breast pump.

[0041] The first cavity 23 has interfaces at both ends for connecting to the air inlet 43 of the first solenoid valve 41 and the first air tube assembly 11, respectively. Similarly, the second cavity 24 has interfaces at both ends for connecting to the air inlet 43 of the second solenoid valve 42 and the second air tube assembly 12, respectively. The adapter 22 can be connected to the air inlet 43 of the first solenoid valve 41 and the first air tube assembly 11 via a plug-in connection or a threaded connection using a locking mechanism. Likewise, it can be connected to the air inlet 43 of the second solenoid valve 42 and the second air tube assembly 12 via a plug-in connection or a threaded connection using a locking mechanism.

[0042] In some embodiments, the adapter 22 is made of an elastomeric material.

[0043] In the above embodiments, the adapter 22 made of elastomeric material can have good shock absorption performance, thereby absorbing and buffering the vibration generated by the air pump assembly 3 during operation, avoiding the impact of the vibration generated by the air pump assembly 3 on the milk collection assembly 1, and effectively improving the practicality of the dual-sided electric breast pump and the user experience.

[0044] In some embodiments, such as Figures 1 to 3 As shown, the air pump assembly 3 includes a pump body 33 and a T-shaped connector 34T. One side of the T-shaped connector 34T is connected to the gas inlet of the pump body 33, and the first air intake port 31 and the second air intake port 32 are both formed on the other side of the T-shaped connector 34T.

[0045] In the above embodiment, the air pump assembly 3 can be connected to the first air tube group 11 and the second air tube group 12 simultaneously using a T-shaped connector 34T, which greatly simplifies the connection structure of the dual-sided electric breast pump and reduces the manufacturing cost and assembly difficulty of the dual-sided electric breast pump.

[0046] The aforementioned T-shaped connector 34T may have a flow chamber for gas flow. The T-shaped connector 34T may also have a gas outlet and two gas inlets respectively connected to the flow chamber. The two gas inlets of the T-shaped connector 34T may be symmetrically arranged. The gas inlet of the pump body 33 may be connected to the gas outlet of the T-shaped connector 34T. The first suction port 31 is constructed as one of the gas inlets, and the second suction port 32 is constructed as the other gas inlet.

[0047] The T-type connector 34T and the pump body 33 can be connected by plug-in connection or by threaded connection using locking parts, etc., and this application does not make specific limitations in this regard.

[0048] In some embodiments, such as Figure 1 and Figure 2 As shown, the host 2 also includes a rechargeable battery 25 and a charging interface 26 disposed in the housing 21. The rechargeable battery 25, the charging interface 26 and the control component 5 are electrically connected to each other to supply power to the control component 5 via the rechargeable battery 25 and / or the charging interface 26.

[0049] In the above embodiments, the control component 5 can be powered directly through the charging interface 26, and the charging battery 25 can be replenished with power through the charging interface 26. Thus, in the absence of a power supply, the power stored in the charging battery 25 can be used to power the control component 5. This allows the dual-sided electric breast pump to meet different usage scenarios and conditions, effectively improving the practicality of the dual-sided electric breast pump.

[0050] In some embodiments, such as Figure 1 and Figure 2As shown, the upper surface of the housing 21 is provided with a display panel 6, which is electrically connected to the control component 5 and is used to display the working status of the dual-sided electric breast pump.

[0051] In the above embodiments, the working status of the dual-sided electric breast pump can be intuitively understood through the display panel 6. This not only improves the intelligence level of the dual-sided electric breast pump, but also greatly facilitates its use by the user, effectively enhancing the convenience and practicality of the dual-sided electric breast pump.

[0052] The aforementioned display panel 6 can be connected to the housing 211 to cover the accommodating space 213 for housing the air pump assembly 3 and the electronically controlled valve assembly 4. The display panel 6 and the housing 211 can be connected by screws or clips, etc., and this application does not make specific limitations in this regard.

[0053] The control component 5 can be connected to the display panel 6 by means of screw connection or snap connection. This application does not specify the connection method between the control component 5 and the display panel 6.

[0054] The aforementioned display panel 6 can be electrically connected to the control component 5 to display the working status of the dual-sided electric breast pump. For example, it can display the operating status of the air pump component 3, the opening and closing of the electric control valve group 4, and other specific working statuses.

[0055] In some embodiments, such as Figure 3 As shown, the air inlet 43 of the first solenoid valve 41 is directly connected to the first air pipe assembly 11, the air inlet 43 of the second solenoid valve 42 is directly connected to the second air pipe assembly 12, the air outlet 44 of the first solenoid valve 41 is directly connected to the first suction port 31, and the air outlet 44 of the second solenoid valve 42 is directly connected to the second suction port 32.

[0056] In the above embodiments, the air pump assembly 3, the electronically controlled valve assembly 4, and the milk collection assembly 1 are all connected by a plug-in method. This not only ensures the tightness between each interface and avoids air leakage, but also simplifies the connection method of the dual-sided electric breast pump, reduces the assembly time of the dual-sided electric breast pump, and further improves the convenience of using the dual-sided electric breast pump.

[0057] The first tracheal tube assembly 11 and the second tracheal tube assembly 12 can be made of an elastomer material so that the first tracheal tube assembly 11 and the second tracheal tube assembly 12 can undergo elastic deformation during the insertion process. This not only ensures the smooth insertion process, but also generates a restoring force when elastic deformation occurs. Under the action of the above force, the tightness of the interface connected to the first tracheal tube assembly 11 and the second tracheal tube assembly 12 can be ensured.

[0058] In some embodiments, such as Figure 2 As shown, the housing 21 is provided with a first through hole 27 and a second through hole 28. The first through hole 27 is correspondingly provided with the first cavity 23 of the adapter 22, and the second through hole 28 is correspondingly provided with the second cavity 24 of the adapter 22.

[0059] In the above embodiments, the interfaces between the air pump assembly 3, the electronically controlled valve assembly 4, and the milk collection assembly 1 can all be located within the accommodating space 213. The housing 21 provides protection for the components located within it, preventing the interfaces from falling off under external force. Furthermore, the first air tube assembly 11 and the second air tube assembly 12 can be connected to the external environment through the first through hole 27 and the second through hole 28, respectively, effectively ensuring the practicality and reliability of the dual-sided electric breast pump.

[0060] The first through hole 27 and the second through hole 28 can be formed on the side wall of the outer shell 211, and the first through hole 27 and the second through hole 28 can be connected to the accommodating space 213 respectively. After the first air tube assembly 11 and the second air tube assembly 12 are connected to the adapter 22, they can pass through the first through hole 27 and the second through hole 28 respectively to extend to the outside of the accommodating space 213.

[0061] The above embodiments are merely exemplary embodiments of this utility model and are not intended to limit this utility model. Those skilled in the art can make various modifications or equivalent substitutions to this utility model within its substance and protection scope, and such modifications or equivalent substitutions should also be considered to fall within the protection scope of this utility model.
