[0002] In today's booming maternal and infant product market, wearable breast pumps have become a powerful tool for many working mothers and breastfeeding mothers due to their unique advantages. However, the closely related issue of charging has gradually become prominent, becoming a major bottleneck restricting the user experience of wearable breast pumps.

[0003] Most products only come with a simple charging cable, so mothers have to search for power outlets while using them. The breast pump can only be placed aside while charging, which not only takes up space, but also makes it easy to accidentally pull the charging cable and interrupt the charging process, affecting the pumping process and adding trouble for busy mothers.

[0004] The advent of breast pump charging devices has improved the user experience by offering portability and the ability to charge anytime, anywhere. However, due to design limitations, when the breast pump is placed inside the charging device, the silicone flange (i.e., the breast shield) tends to adhere to the inner wall of the charging device, making it difficult to remove the breast pump. Furthermore, the storage devices used to hold the breast pump, as well as the dustproof devices used for dust protection, also suffer from the same problems after being connected to the breast pump.

[0069] Example 1:

[0070] like Figures 1 to 5 As shown, the protective device 100 provided in this embodiment of the present invention is applied to a breast pump 200, including a housing component 10. The housing component 10 is provided with a receiving groove 11, which is used to accommodate at least a portion of the breast pump 200. In specific applications, at least one side of the breast pump 200 where the breast shield 202 is provided is accommodated in the receiving groove 11 to prevent dust and other impurities from entering the breast pump 200 through the opening of the breast shield 202 and contaminating the milk channel inside the breast pump 200. Therefore, it can protect the breast pump 200.

[0071] In one embodiment, the protective device 100 further includes a charging component 20 connected to the housing component 10 for charging the breast pump 200 housed in the receiving slot 11. Thus, the protective device 100 can both protect the breast pump 200 and charge it. In specific applications, wireless or wired charging methods can be used to charge the breast pump 200. Of course, in other embodiments, the protective device 100 may not include the charging component 20.

[0072] Please see Figure 2 , Figure 3 , Figures 8 to 10 The protective device 100 also includes a desorption auxiliary structure 30, which is disposed in the receiving groove 11. When the breast pump 200 is placed in the receiving groove 11, the desorption auxiliary structure 30 is used to prevent the formation of a closed space between the breast shield 202 of the breast pump 200 and the receiving groove 11.

[0073] For specific applications, please refer to Figure 3 , Figures 6 to 10 The breast pump 200 includes a milk-expressing body 201 and a breast shield 202. The breast shield 202 is installed on the milk-expressing body 201 and is funnel-shaped. When using the breast pump 200 to express milk, the breast shield 202 is placed over the breast. Typically, the breast shield 202 is made of silicone to create a closed space between the breast shield 202 and the breast when placed on the breast. Because the breast shield 202 is made of silicone, when the breast pump 200 is placed in the receiving slot 11, the breast shield 202 easily forms a sealed space with the wall of the receiving slot 11, making it difficult to remove the breast pump 200 from the receiving slot 11. By setting the desorption auxiliary structure 30, when the breast pump 200 is placed in the receiving groove 11, the desorption auxiliary structure 30 can prevent the formation of a closed space between the breast shield 202 of the breast pump 200 and the groove wall of the receiving groove 11, so that the inner cavity of the breast pump 200 and the outside of the breast pump 200 are kept in communication. In this way, excessive suction force is avoided between the breast pump 200 and the groove wall of the receiving groove 11, which is conducive to removing the breast pump 200 from the receiving groove 11.

[0074] It should be noted that in this embodiment, when the circumferential part of the breast shield 202 is tightly fitted to the groove wall of the receiving groove 11, even if a certain area inside the breast shield 202 is not tightly fitted to the groove wall, it is considered that a sealed space is formed between the breast shield 202 and the groove wall of the receiving groove 11.

[0075] In one embodiment, the desorption aid structure 30 includes a protrusion 31 and / or a groove. By configuring the desorption aid structure 30 as a protrusion 31 and / or a groove, when the breast pump 200 is accommodated in the receiving groove 11, an airflow channel is formed between the breast shield 202 and the groove wall of the receiving groove 11 under the action of the protrusion 31 or the groove, thereby preventing the formation of a sealed space between the breast shield 202 and the receiving groove 11. In this embodiment, the desorption aid structure 30 includes a protrusion 31. It is understood that in other embodiments, the desorption aid structure 30 may also include a groove, or the desorption aid structure 30 may also include a protrusion 31 and a groove.

[0076] In one embodiment, at least two protrusions 31 are provided. By providing at least two protrusions 31, it is more beneficial to prevent the formation of a sealed space between the breast shield 202 and the receiving groove 11. In specific applications, the protrusions 31 are arranged at intervals.

[0077] Please see Figure 4 and Figure 6The receiving groove 11 has a bottom wall 111 and a side wall 112 connected to the bottom wall 111. The bottom wall 111 is positioned opposite to the opening of the receiving groove 11. When the breast pump 200 is placed in the receiving groove 11, the breast shield 202 of the breast pump 200 faces the bottom wall 111. Of course, in other embodiments, the breast shield 202 of the breast pump 200 may also face the side wall 112.

[0078] In one embodiment, the desorption aid structure 30 is disposed on the bottom wall 111 of the tank and near the side wall 112 of the tank. That is, the protrusion 31 and the groove are disposed on the bottom wall 111 of the tank and near the side wall 112 of the tank. This arrangement ensures that the inner cavity of the breast pump 200 and the outside of the breast pump 200 remain in communication, effectively preventing excessive suction force from forming between the breast shield 202 and the bottom wall 111 of the tank.

[0079] Please see Figure 3 , Figure 4 and Figure 6 The receiving slot 11 is also equipped with a support platform 40, which is used to support the milk pump body 201 of the breast pump 200. In this way, the milk pump body 201 can be stably housed in the receiving slot 11 by the support platform 40. Even when the breast pump 200 is not equipped with the breast shield 202, it can be placed in the receiving slot 11 for charging, which expands the application scenarios for charging the breast pump 200 (with or without the breast shield 202).

[0080] In practical applications, the breast pump body 201 includes a main unit 2011 and a milk storage container 2012, and the support platform 40 can be used to support the main unit 2011. Thus, even without the milk storage container 2012 installed, the breast pump 200 can be placed in the receiving slot 11 for charging. For example, when the breast shield 202 and the milk storage container 2012 are disassembled for cleaning, the main unit 2011 can be placed separately in the receiving slot 11 for charging.

[0081] In one embodiment, the support platform 40 is disposed on the side wall 112 or the bottom wall 111 of the trough, and is used to support the edge area of ​​the breast pump body 201 facing the breast shield 202. In this way, when the breast pump 200 is housed in the receiving trough 11 and the breast shield 202 of the breast pump 200 is positioned facing the bottom wall 111 of the trough, the support platform 40 can support the breast pump body 201 regardless of whether the breast pump body 201 is assembled with the breast shield 202.

[0082] In one embodiment, the support platform 40 is a step 41 formed on the sidewall 112 of the groove, or a boss provided on the bottom wall 111 of the groove. In this embodiment, the support platform 40 is a step 41 formed on the sidewall 112 of the groove. It can be understood that in other embodiments, the support platform 40 may also be a boss provided on the bottom wall 111 of the groove.

[0083] In one embodiment, two steps 41 are provided, and the two steps 41 are arranged opposite to each other. This ensures the stability of the milk pump body 201 supported on the steps 41. It is understood that in other embodiments, multiple steps 41 may be provided, or a single step 41 may be provided. When a single step 41 is provided, the step 41 may be arc-shaped or annular.

[0084] In one embodiment, the support platform 40 is a desorption auxiliary structure 30. In specific applications, the support platform 40 can be configured to have sufficient height so that when the breast pump 200 is housed in the receiving groove 11, the breast pump body 201 is supported by the support platform 40. Because the support platform 40 is sufficiently high, the breast shield 202 and the bottom wall 111 of the groove can be spaced apart, thereby preventing the formation of a sealed space between the breast shield 202 and the bottom wall 111. Of course, in other embodiments, the support platform 40 may not be configured as a desorption auxiliary structure 30.

[0085] Please see Figure 4 , Figure 5 , Figure 8 and Figure 9 The receiving groove 11 is also provided with a raised section 50, which is disposed on the bottom wall 111 of the groove. When the breast pump 200 is placed in the receiving groove 11, the raised section 50 extends into the breast shield 202. In specific applications, the breast shield 202 is funnel-shaped and has a breast pumping channel 203. When the breast shield 202 is placed on the breast, the nipple extends into the breast pumping channel 203. By providing the raised section 50, when the breast pump 200 is placed in the receiving groove 11, the raised section 50 extends into the breast shield 202 and into the breast pumping channel 203, which can pre-position the breast pump 200. Of course, in other embodiments, the raised section 50 may not be provided in the receiving groove 11.

[0086] In one embodiment, at least two receiving slots 11 are provided, and the at least two receiving slots 11 are arranged side by side. In this way, the protection device 100 can charge at least two breast pumps 200 simultaneously. By arranging at least two receiving slots 11 side by side, the regularity of the arrangement of the receiving slots 11 is improved, which helps to reduce the space occupied by the protection device 100.

[0087] In one embodiment, the shape and size of the receiving slot 11 are matched to the shape and size of the breast pump 200. This prevents excessive movement of the breast pump 200 after it is placed in the receiving slot 11.

[0088] Please see Figure 4 , Figure 5 , Figure 8 and Figure 11The protective device 100 also includes a first limiting member 60, which is disposed on the housing component 10 and is used to cooperate with the second limiting member 204 of the breast pump 200 to limit the breast pump 200 within the receiving groove 11. By setting the first limiting member 60 and cooperating with the second limiting member 204, the breast pump 200 is limited within the receiving groove 11, which can prevent the breast pump 200 from shaking when the protective device 100 is moved, and facilitates charging the breast pump 200 while the protective device 100 is in a moving state.

[0089] In one embodiment, the first limiting member 60 and the second limiting member 204 are magnetically attracted magnets. It is understood that in other embodiments, one of the first limiting member 60 and the second limiting member 204 may be a snap-fit, and the other may be a slot that engages with the snap-fit. In this embodiment, the first limiting member 60 and the second limiting member 204 are magnetically attracted magnets, and two magnets are provided for each breast pump 200; correspondingly, the breast pump 200 also has two magnets.

[0090] Please see Figure 5 The housing component 10 includes an inner shell 12 and an outer shell 13. The inner shell 12 is disposed within the outer shell 13, and a receiving groove 11 is formed in the inner shell 12. The outer shell 13 includes an injection-molded support layer and a flexible protective layer adhered to the injection-molded support layer. The injection-molded support layer provides support, giving the outer shell 13 a certain strength, while the flexible protective layer provides flexibility, thus giving the outer shell 13 both strength and flexibility. In specific applications, the injection-molded support layer can be made of plastic material, and then the flexible protective layer can be adhered to the injection-molded support layer through a hot-pressing composite process.

[0091] In one embodiment, please refer to Figure 5 The outer casing 13 includes a first outer casing 131 and a second outer casing 132. The inner casing 12 is disposed inside the first outer casing 131, and the second outer casing 132 is connected to the first outer casing 131 and covers the receiving groove 11. In this way, when the breast pump 200 is placed in the receiving groove 11, the second outer casing 132 covers the receiving groove 11, which can encapsulate the breast pump in the housing component 10. This protective device 100 can store the breast pump and is also convenient for carrying the breast pump 200.

[0092] For ease of description, the injection-molded support layer of the first outer shell 131 is defined as the first injection-molded support layer 1311, the flexible protective layer of the first outer shell 131 is defined as the first flexible protective layer 1312, the injection-molded support layer of the second outer shell 132 is defined as the second injection-molded support layer 1321, and the flexible protective layer of the second outer shell 132 is defined as the second flexible protective layer 1322.

[0093] Please refer to Figure 11 and Figure 12 The first outer shell 131 includes a first injection-molded support layer 1311 and a first flexible protective layer 1312. The inner shell 12 and the first flexible protective layer 1312 are distributed on opposite sides of the first injection-molded support layer 1311. The first flexible protective layer 1312 is located on the outer side of the first injection-molded support layer 1311 to improve the flexibility of the first outer shell 131. The second outer shell 132 includes a second injection-molded support layer 1321 and a second flexible protective layer 1322. The second flexible protective layer 1322 has two layers, which are respectively disposed on opposite sides of the second injection-molded support layer 1321, thus improving the flexibility of the second outer shell 132. When the breast pump 200 in the receiving groove 11 shakes, the second flexible protective layer 1322 disposed on the inner side of the second injection-molded support layer 1321 can cushion the breast pump 200, thereby preventing the breast pump 200 from being bumped or knocked.

[0094] In one embodiment, the housing component 10 includes a first housing 14 and a second housing 15. A receiving groove 11 is formed in the first housing 14, and the second housing 15 is movably or detachably connected to the first housing 14 to cover the receiving groove 11. By providing the second housing 15 to cover the receiving groove 11, the breast pump 200 can be completely housed inside the housing component 10, facilitating carrying the breast pump 200 during charging. In specific applications, the first outer shell 131 and the inner shell 12 can form the first housing 14, and the second outer shell 132 can form the second housing 15. It is understood that in other embodiments, the housing component 10 may not include the second housing 15.

[0095] In one embodiment, the second housing 15 is rotatably connected to the first housing 14, and the housing component 10 further includes a zipper 16, which connects the first housing 14 and the second housing 15. Thus, the housing component 10 can be opened or closed via the zipper 16, making operation convenient and quick.

[0096] Please see Figure 3 The zipper 16 includes a first chain belt 161, a second chain belt 162, and a slider 163 connected between the first chain belt 161 and the second chain belt 162. The first chain belt 161 is clamped to the first housing 14, and the second chain belt 162 is clamped to the second housing 15. By clamping the first chain belt 161 to the first housing 14 and the second chain belt 162 to the second housing 15, compared to the technical solution where the first chain belt 161 and the second chain belt 162 are completely connected to the outside of the housing, the distance between the first housing 14 and the second housing 15 is shortened, which helps to reduce the space occupied by the protective device 100 and improves the aesthetics of the outer casing 13 components.

[0097] Please see Figures 4 to 6The charging component 20 includes a power supply 21 and a first charging connector 22 electrically connected to the power supply 21. The first charging connector 22 is connected to the housing component 10 and is used to electrically connect to the second charging connector 205 of the breast pump 200 when the breast pump 200 is placed in the receiving slot 11. In specific applications, the first charging connector 22 and the second charging connector 205 are in contact to achieve electrical connection. This arrangement allows the charging component 20 to charge the breast pump 200 via wired charging. Furthermore, using this protection device 100 to charge the breast pump 200 avoids the inconvenience of users searching for power outlets. In addition, by providing the receiving slot 11, placing the breast pump 200 in the receiving slot 11 for charging prevents the breast pump 200 from being pulled on the charging cable during charging, thus avoiding charging interruption.

[0098] Please see Figure 2 , Figure 4 , Figures 13 to 16 The first charging connector 22 includes a first connector body 221, a first alignment component 222, and a reset component 223. The first connector body 221 is movably connected to the housing component 10, and both the first alignment component 222 and the reset component 223 are connected to the first connector body 221. The second charging connector 205 includes a second connector body 2051 and a second alignment component 2052 connected to the second connector body 2051. The first alignment component 222 is used to align and connect with the second alignment component 2052 of the breast pump 200 when the breast pump 200 is placed in the receiving slot 11, so as to drive the first connector body 221 to move closer to the breast pump 200 and to electrically connect with the second connector body 2051 of the breast pump 200. The reset component 223 is used to drive the first connector body 221 to reset when the first alignment component 222 and the second alignment component 2052 are disengaged.

[0099] In practical applications, when the first alignment component 222 and the second alignment component 2052 are aligned and connected, the first connector body 221 is moved towards the breast pump 200, so that the first connector body 221 and the second connector body 2051 are facing each other and in contact, thereby achieving an electrical connection between the first connector body 221 and the second connector body 2051. When the first alignment component 222 and the second alignment component 2052 are disengaged, that is, when the breast pump 200 is removed from the receiving slot 11, the reset component 223 drives the first connector body 221 to reset.

[0100] In one embodiment, the housing component 10 further includes a receiving space 17 and a through hole 18 connecting the receiving space 17 and the receiving groove 11. The first charging connector 22 is housed within the receiving space 17, and the first connector body 221 can pass through the through hole 18 and extend into the receiving groove 11. The first alignment component 222 is used to drive the first connector body 221 through the through hole 18 and into the receiving groove 11 when it is aligned and connected with the second alignment component 2052 of the breast pump 200, and to electrically connect with the second connector body 2051 of the breast pump 200. The reset component 223 is used to drive the first connector body 221 out of the receiving groove 11 when the first alignment component 222 and the second alignment component 2052 are disengaged.

[0101] For specific applications, please refer to Figure 2 and Figure 16 When the breast pump 200 is not placed in the receiving slot 11, the first charging connector 22 is located in the receiving space 17, that is, outside the receiving slot 11. Therefore, during the process of placing the breast pump 200 into the receiving slot 11, the first charging connector 22 will not interfere with the breast pump 200. Please refer to Figure 2 and Figure 14 When the breast pump 200 is placed in the receiving groove 11, the first connector body 221 passes through the perforation 18 and extends into the receiving groove 11 to achieve contact and electrical connection between the first connector body 221 and the second connector body 2051. The receiving space 17 may be formed between the inner shell 12 and the first outer shell 131, and the perforation 18 may be formed in the inner shell 12.

[0102] In one embodiment, the first alignment component 222 and the second alignment component 2052 are magnets that attract each other, and the reset component 223 is a spring or an elastic sheet.

[0103] In practical applications, the first alignment component 222 and the second alignment component 2052 are magnetically attracted to each other, aligning and connecting them. This allows the first connector body 221 and the second connector body 2051 to face each other and be in contact. When the first alignment component 222 and the second alignment component 2052 are magnetically attracted, the spring or elastic sheet is in a compressed state, wherein the compressive force of the spring or elastic sheet is less than the magnetic attraction force of the first alignment component 222 and the second alignment component 2052. When the first alignment component 222 and the second alignment component 2052 are separated, the first alignment component 222 returns to its original position under the action of the compressive force of the spring or elastic sheet.

[0104] Please see Figure 4 , Figures 13 to 17The housing component 10 also includes a connector 19, which is connected to the inner housing 12 and / or the first outer housing 131 and is located between the inner housing 12 and the first outer housing 131. The first connector body 221 is movably connected to the connector 19, and a spring or elastic sheet is elastically connected between the first connector body 221 and the connector 19. The portion of the connector 19 that connects to the first connector body 221 is located in the receiving space 17 and corresponds to the through hole 18.

[0105] Further, please refer to Figures 1 to 4 , Figure 6 This utility model embodiment also provides a breast pumping system, including a breast pump 200 and the aforementioned protective device 100. The breast pump 200 is detachably housed in a receiving slot 11, and a charging component 20 is used to charge the breast pump 200. By employing the aforementioned protective device 100, when the breast pump 200 is housed in the receiving slot 11, a closed space is not easily formed between the breast shield 202 and the receiving slot 11, allowing the user to easily remove the breast pump 200 from the receiving slot 11.

[0106] Please see Figure 4 and Figure 5 The charging component 20 includes a first charging connector 22, and the breast pump 200 includes a second charging connector 205. When the breast pump 200 is housed in the receiving slot 11, the first charging connector 22 and the second charging connector 205 are electrically connected. This arrangement enables the protection device 100 to charge the breast pump 200 via wired charging.

[0107] Please see Figure 6 and Figure 7 The breast pump 200 also includes a milk suction channel 203 and a milk pouring outlet 206. The milk suction channel 203 is formed in the breast shield 202, and the milk pouring outlet 206 is formed in the milk storage container 2012. The milk suction channel 203 is used to transport milk expressed from the breast, and the milk pouring outlet 206 facilitates the pouring of milk from the milk storage container 2012. The second charging connector 205 is located on the first side of the breast pump 200, and both the milk suction channel 203 and the milk pouring outlet 206 are located on a different side from the second charging connector 205. Since milk flows through both the breast pump channel 203 and the milk outlet 206, milk residue is easily left behind. Furthermore, both the breast shield 202 and the milk storage container 2012 require cleaning, and cleaning water residue is easily left behind. By placing the breast pump channel 203 and the milk outlet 206 on opposite sides of the second charging connector 205, it is possible to prevent milk or cleaning water from contaminating the second charging connector 205 and the first charging connector 22, thereby avoiding poor contact between the second charging connector 205 and the first charging connector 22.

[0108] In this embodiment, the milk inlet 206 is located on the second side opposite to the first side, and the milk suction channel 203 is located at the bottom of the breast pump 200. In specific applications, the locations of the milk suction channel 203 and the milk inlet 206 are not limited by the accompanying drawings. It should be noted that the sides and bottom of the breast pump 200 refer to the sides and bottom corresponding to when the breast pump 200 is housed in the receiving groove 11.

[0109] Example 2:

[0110] The main difference between the breast pump 200 and the breast pumping system provided in this embodiment and those in Embodiment 1 lies in the different configuration of the housing component 10. Specifically, in Embodiment 1, the housing component 10 includes a first housing 14 and a second housing 15; while in this embodiment, the housing component 10 includes a housing body 71, an extension 72, and a snap-fit ​​portion 73.

[0111] Please see Figure 18 and Figure 19 The housing component 10 includes a housing body 71, an extension 72, and a snap-fit ​​part 73. A receiving groove 11 is disposed in the housing body 71, and the extension 72 connects the housing body 71 and the snap-fit ​​part 73. The snap-fit ​​part 73 is used to snap into the snap-fit ​​groove of the breast pump 200. In specific applications, the protective device 100 and the breast pump 200 can be connected through the cooperation of the snap-fit ​​part 73 and the snap-fit ​​groove. The side of the breast pump 200 with the breast shield 202 is accommodated in the receiving groove 11. The protective device 100 protects the breast pump 200 and prevents dust and other impurities from entering the milk channel inside the breast pump 200.

[0112] Apart from the differences mentioned above, the breast pump 200, breast pumping system and its auxiliary components provided in this embodiment can be designed with reference to Embodiment 1, and will not be described here again.
