Description

Electric breast pump connector and electric breast pump having the connector Technical Field

[0001] The present invention relates to an electric breast pump, and more particularly, to an electric breast pump connector with an improved structure. Background Art

[0002] Electric breast pumps on the market typically feature an electronically controlled housing for extracting milk and a milk collection bottle. These systems can adjust the frequency and suction strength to match the baby's sucking speed and force. Further improvements have been made to the housing, where the breast contacts are located, by incorporating a heating element. This heating element creates a warming effect when the housing contacts the body, alleviating the discomfort previously experienced by women using the device in cold weather. It also enhances blood circulation in the breasts, improving milk extraction.

[0003] However, conventional electric breast pumps integrate a metal heating element within a plastic housing. Due to the different materials of the heating element and the housing, repeated use, combined with the effects of temperature fluctuations in the surrounding environment, can cause the plastic housing to expand and contract, potentially damaging the heating element. Furthermore, the components must be disassembled and reassembled before and after use, raising the question of whether the assembly structure can maintain stable electrical connections during use and resist damage after repeated disassembly and assembly.

[0035] In one embodiment, the heating unit 123 may further include a first protruding portion 124 , wherein the fourth through hole 125 may be defined in the first protruding portion 124 .

[0036] In one embodiment, the cover 21 may further include a second protruding portion 213, wherein the second through hole 2122 may be defined in the second protruding portion 213. Preferably, the second protruding portion 213 may be disposed on the other side of the cover 21 relative to the first through hole 2121 to prevent interference between the power cord 22 and the hollow conduit 23 passing through the first through hole 2121 and the second protruding portion 213. Specifically, the first protruding portion 124 and the second protruding portion 213 can eliminate structural obstruction between the adapter 1 and the conduit module 2, allowing the first electrical connection portion 121 to easily engage with the second electrical connection portion 221.

[0037] In one embodiment, the first joint portion 11 may further include a first positioning portion 111, and the extension portion 211 of the cover 21 may further include a second positioning portion 2112, wherein the first positioning portion 111 may engage with the second positioning portion 2112.

[0038] According to the present invention, the first positioning portion 111 and the second positioning portion 2112 can be configured to engage with each other, electrically connecting the first electrical connection portion 121 to the second electrical connection portion 221. In one embodiment, as shown in FIG1 , the first positioning portion 111 can be a convex portion, and the second positioning portion 2112 can be a concave portion. In other embodiments, the first positioning portion 111 can be a concave portion (not shown), and the second positioning portion 2112 can be a convex portion (not shown). The shapes or structures of the first positioning portion 111 and the second positioning portion 2112 are not limited to this.

[0039] Please refer to Figure 3, which illustrates an exemplary embodiment of the adapter and cover of the electric breast pump connector of the present invention. In one embodiment, the first connecting portion 11 may further include opposing third and fourth positioning portions 112 and 113, and the extension portion 211 may further include fifth and sixth positioning portions 2113 and 2114. The third positioning portion 112 may engage with the fifth positioning portion 2113, and the fourth positioning portion 113 may engage with the sixth positioning portion 2114. In this embodiment, the interengaging of multiple positioning portions facilitates quick and accurate assembly of the cover 21 and the first connecting portion 11.

[0040] In one embodiment, the first positioning portion 111 may be disposed between the third positioning portion 112 and the fourth positioning portion 113, and the second positioning portion 2112 may be disposed between the fifth positioning portion 2113 and the sixth positioning portion 2114. Preferably, the width D1 of the first positioning portion 111 may be greater than or less than the width D2 of the third positioning portion 112 and the fourth positioning portion 113, and the width D3 of the second positioning portion 2112 may be greater than or less than the width D4 of the fifth positioning portion 2113 and the sixth positioning portion 2114. Specifically, as shown in FIG3 , the width D1 of the first positioning portion 111 can be smaller than the width D2 of the third positioning portion 112 and the fourth positioning portion 113, and the width D3 of the second positioning portion 2112 can be smaller than the width D4 of the fifth positioning portion 2113 and the sixth positioning portion 2114. This allows the user to utilize the size differences when assembling the cover 21 and the first engaging portion 11 to engage the first positioning portion 111 with the corresponding second positioning portion 2112, and the third positioning portion 112 and the fourth positioning portion 113 can be smoothly engaged with the fifth positioning portion 2113 and the sixth positioning portion 2114, respectively. When the cover 21 is engaged with the first engaging portion 11, the first electrical connection portion 121 is accurately aligned with the second electrical connection portion 221 and is electrically connected to the second electrical connection portion 221.

[0041] In one embodiment, the third positioning portion 112, the fourth positioning portion 113, the fifth positioning portion 2113, and the sixth positioning portion 2114 may have corresponding shapes and structures that engage with each other. In one embodiment, as shown in FIG3 , the third positioning portion 112 and the fourth positioning portion 113 may be convex portions, and the fifth positioning portion 2113 and the sixth positioning portion 2114 may be corresponding concave portions. In other embodiments, the third positioning portion 112 and the fourth positioning portion 113 may also be concave portions (not shown), and the fifth positioning portion 2113 and the sixth positioning portion 2114 may also be corresponding convex portions (not shown), but the shapes or structures are not limited to this.

[0042] According to the aforementioned component and structural design of the present invention, during actual operation, when the first positioning portion 111 and the second positioning portion 2112 engage, the first electrical connection portion 121 is connected to the second electrical connection portion 221, eliminating the need for the user to separately confirm whether the first electrical connection portion 121 and the second electrical connection portion 221 are properly connected. When the second coupling portion 241 of the fastener 24 engages the first coupling portion 2111, the stability of the cover 21 and the first coupling portion 11 is further enhanced. Even if the electric breast pump connector of the present invention vibrates or moves during use, the first electrical connection portion 121 and the second electrical connection portion 221 will maintain electrical connection, preventing loosening and causing the connector to cease operation.

[0043] Please refer to Figures 1 to 3 . In one embodiment, the extension portion 211 may have a top portion 2115 and a bottom portion 2116 opposite each other, wherein the top portion 2115 may be adjacent to the spacer 212 and the bottom portion 2116 may be adjacent to the first joint portion 11. Preferably, the extension portion 211 may include a plurality of plates 2117 , wherein at least one gap 2118 may be formed between the plurality of plates 2117 , wherein at least one gap 2118 has an opening 2119 formed in the bottom portion 2116 . In this embodiment, when the second coupling portion 241 of the fastener 24 is separated from the first coupling portion 2111, the opening 2119 at the bottom 2116 of the gap 2118 is larger, so that the circumference of the bottom 2116 of the extension portion 211 can be slightly larger than the circumference of the top 2115 of the extension portion 211, so that the second positioning portion 2112 can be easily engaged with the corresponding first positioning portion 111, and the fifth positioning portion 2113 and the sixth positioning portion 2114 can also be easily engaged with the corresponding third positioning portion 112 and the fourth positioning portion 113. When the second coupling portion 241 of the fastener 24 is coupled to the first coupling portion 2111, the opening 2119 of the gap 2118 is smaller, so that the circumference of the bottom 2116 of the extension portion 211 is reduced to slightly larger than the circumference of the first coupling portion 11, so that the extension portion 211 is firmly coupled to the first coupling portion 11, further increasing the tightness of the coupling between the cover body 21 and the adapter 1, so that the gas connected between the hollow conduit 23 and the third through hole 2123 is not easily discharged from the gap where the first coupling portion 11 and the extension portion 211 are coupled, but dissipated into the surrounding environment.

[0044] According to the present invention, the cover 21 is first joined to the first connecting portion 11 via the opposing positioning portions, and then the two are securely connected via the fastener 24. This allows the electric breast pump connector of the present invention to accurately connect the first electrical connection portion 121 and the second electrical connection portion 221 during disassembly and assembly, while also preventing deformation or damage to the cover 21 or the first connecting portion 11 at the joint due to repeated disassembly and assembly.

[0045] In one embodiment, as shown in FIG1 , the fastener 24 may further include an anti-slip structure 242 , such as, but not limited to, a plurality of intermittently arranged convex or concave structures, or the anti-slip structure 242 may be made of an anti-slip material. The anti-slip structure 242 may be disposed on the other side of the fastener 24 from which the second coupling portion 241 is disposed.

[0046] In one embodiment, the side of the cover 21 facing the adapter 1 may include a first protrusion 214, wherein the first protrusion 214 may be formed on the periphery of the third through hole 2123. Preferably, the height of the first protrusion 214 may gradually decrease from the third through hole 2123 outward. More preferably, the height of the first protrusion 214 may be, for example, a conical or frustum-shaped structure with a height gradually decreasing from the periphery of the third through hole 2123 outward, but is not limited to this. In other embodiments, a groove 216 may also be formed around the first protrusion 214. The first protrusion 214 and the groove 216 structure facilitate the flow of gas generated by the air pressure regulating assembly. In another embodiment, the side of the cover 21 facing the adapter 1 may also include a second protrusion 215.

[0047] Please refer to Figures 1, 2, and 4. Figure 4 is a schematic diagram of an exemplary embodiment of an electric breast pump connector and an electric breast pump having the connector according to the present invention. A second aspect of the present invention provides an electric breast pump. In addition to the components and structure of the electric breast pump connector embodiments according to the first aspect of the present invention, the electric breast pump may also include a milk collection bottle 3. The milk collection bottle 3 is detachably coupled to the third joint 13.

[0048] In one embodiment, the electric breast pump of the present invention may further include a diaphragm 4. As shown in FIG1 , the diaphragm 4 may be disposed between the spacer 212 and the first engaging portion 11. Preferably, the diaphragm 4 may be mounted on the second raised portion 215 of the cover 11. In this embodiment, the diaphragm 4 may have a recessed structure. When mounted on the second raised portion 215, the diaphragm 4 forms a gas-retaining space between the diaphragm 4 and the spacer 212.

[0049] In one embodiment, the electric breast pump of the present invention may further include a check valve 5. In this embodiment, the third connecting portion 13 may include a third coupling portion 131, on which the check valve 5 may be disposed. Specifically, the third coupling portion 131 may be an annular structure, and the check valve 5 may be an annular structure having a circumference slightly larger than the third coupling portion 131, such that the check valve 5 is securely mounted on the third coupling portion 131.

[0050] Please refer to Figures 5 and 6 . In one embodiment, the electric breast pump of the present invention further includes a main unit 6, which may include a housing 61, a pump 62, a power module 63, and a control unit 64. The pump 62 may be disposed within the housing 61 and connected to the hollow conduit 23. As previously described, the pump 62 may engage and communicate with the third through-hole 2123 of the spacer 212 through the hollow conduit 23. The power module 63 may be disposed within the housing 61 to provide power to the heating unit 123 and the pump 62, which are electrically connected to the power cord 22. In one embodiment, the power module 63 may be, for example, but not limited to, a disposable or rechargeable battery unit, which transmits operating power to the heating unit 123 or the pump 62 via the power cord 22. The power module 63 may also be a transformer that connects to the mains or other external power source and converts operating power for transmission to the heating unit 123 or the pump 62 via the power cord 22. The control unit 64 can be set in the shell 61 to control the operation of the heating unit 123, the pump 62 and the power module 63, such as but not limited to turning on or off the heating unit 123 or the pump 62, adjusting the intensity of the heating unit 123 or the pump 62, setting the working time or cycle of the heating unit 123 or the pump 62, turning on or off the power module 63, controlling the charging status of the power module 63, etc.

[0051] In one embodiment, the electric breast pump of the present invention may further include a display unit 65. The display unit 65 may be disposed on a surface of the housing 61 and is used to display the operating status of the main unit 6. This may include, but is not limited to, the on / off status of the heating unit 123 or the pump 62, the current intensity of the heating unit 123 or the pump 62, the operating time or cycle of the heating unit 123 or the pump 62, or the on / off or charging / discharging status of the power module 63. In one embodiment, the display unit 65 may be composed of, for example, a light-emitting diode unit or various types of liquid crystal displays, but is not limited thereto.

[0052] In one embodiment, the main unit 6 further includes a slot 66 and a port 67 disposed on the surface of the housing 61. The slot 66 can be used to connect the pump 62 to the hollow conduit 23, and the port 67 can be used to electrically connect the power module 63 to the power cord 22. Specifically, the slot 66 can be, for example, but not limited to, a hollow tube, allowing the hollow conduit 23 to be inserted into the slot 66 while maintaining an airtight seal. The port 67 can be, for example, but not limited to, a USB Type-C, micro USB, or mini USB port. The other end of the power cord 22, which has the second electrical connection portion 221, can serve as a connection terminal for the port 67.

[0053] Please refer again to Figures 1 to 5. As previously mentioned, the diaphragm 4 can be positioned over the second raised portion 215 and disposed between the spacer 212 and the first joint 11. As shown in Figure 1, the diaphragm 4 can have a recessed structure. When positioned over the second raised portion 215, it forms a gas-retaining space between the spacer 211 and the second raised portion 215, thereby blocking the flow of gas between the third through-hole 2123 and the first joint 11. Therefore, when the user attaches the cup body 122 to the breast, the control unit 64 can adjust the suction force of the pump 62. When the pump 62 is connected to the hollow conduit 23 and generates suction, it actually extracts air between the spacer 212 and the diaphragm 4. The combination of the extension 211 and the fastener 24 increases the tightness between the cover 21 and the first joint 11, preventing the extracted air from escaping from the joint and causing pressure fluctuations within the adapter 1. Because the cover 21 and the first joint 11 fit tightly, the suction strength of the pump 62 can be adjusted to correspond to the pressure within the adapter 1. The cyclical contraction and expansion of the diaphragm 4 causes the pressure within the adapter 1 cavity to change, generating suction that stimulates the breast and extracts milk. The extracted milk enters the space within the adapter 1 through the cup body 122. As the diaphragm 4 continues to contract and expand, the structure of the second protrusion 215 and / or the first protrusion 214 and the groove 216 prevents the diaphragm 4 from completely covering the third through-hole 2123 during contraction, preventing a vacuum-tight state. In addition, due to the barrier effect of the diaphragm 4, milk can be prevented from entering the hollow conduit 23 through the third through hole 2123, and will enter the milk collecting bottle 3 through the opening of the third joint 13 for storage.

[0054] In the embodiment of the electric breast pump of the present invention that includes a check valve 5, the check valve 5 can be coupled to the third connecting portion 13. After milk passes through the opening of the third connecting portion 13, it then passes through the check valve 5. The check valve 5 prevents milk that has entered the milk collection bottle 3 from being sucked back into the first connecting portion 11 or the second connecting portion 12 by suction, potentially causing contamination or mechanical damage.
