[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0034] See also Figure 1A The embodiment of the present application provides a wearable breast pump, which mainly includes a main unit component 10 and a milk bowl component 20. The milk bowl component 20 is used to be worn on the breast of a human body, and the main unit component 10 is used to provide suction force for the milk bowl component 20 to absorb milk, so as to absorb the milk in the breast and store it in the milk bowl component 20.

[0035] To facilitate cleaning, the main unit assembly 10 and the milk bowl assembly 20 of the wearable breast pump of this embodiment are detachably connected. When the milk bowl assembly 20 needs to be cleaned after use, the milk bowl assembly 20 can be separated from the main unit 20 first to prevent water from entering the electrical components on the main unit assembly 10, which is convenient and practical.

[0036] When the milk bowl assembly 20 and the main unit assembly 10 are designed to be detachable, if the milk bowl assembly 20 is installed on one end of the main unit assembly 10, or the main unit assembly 10 is installed to one end of the milk bowl assembly 20, it may cause the user to use too much force when grasping one of the main unit assembly 10 and the milk bowl assembly 20, resulting in the main unit assembly 10 and the milk bowl assembly 20 accidentally separating, causing the other part of the wearable breast pump that is not grasped to fall, causing the milk in the milk bowl assembly 20 to spill, and also causing the device to break, resulting in a poor experience.

[0037] Based on the above considerations, combined Figure 1A and Figure 2 As shown, an embodiment of the present application provides a wearable breast pump, including a main body component 10 and a milk bowl component 20, the main body component 10 has a first surface P facing the human body and a first surface T facing away from the human body, a receiving cavity 100 extending in the direction of the first surface P is formed on the first surface T of the main body component 10, and the milk bowl component 20 is embedded in the receiving cavity 100.

[0038] The “first side P” refers to the side of the host component 10 facing the human body, that is, Figure 1A Right side surface shown.

[0039] By providing a receiving cavity 100 extending along the thickness direction of the main body component 10 on the side facing away from the first surface P, the main body component 10 can be used to surround the milk bowl component 20, and the main body component 10 can be used as the main shell of the wearable breast pump. When the milk bowl component 20 is installed in the receiving cavity 100 of the main body component 10, the milk bowl component 20 is surrounded by the main body component 10. When the user operates the breast pump, he only needs to grab the main body component 10, so the milk bowl component 20 and the main body component 10 will not be easily separated, which can prevent the product from accidentally falling or milk spilling.

[0040] In one embodiment, Figure 2 As shown, the accommodating cavity 100 penetrates the thickness direction of the main unit component 10, that is, the accommodating cavity 100 penetrates to the first surface P, so that the accommodating cavity 100 inside the main unit component 10 is formed as a through hole, and the milk bowl component 20 integrates the milk bowl 21 and the breast collecting shield 22, and the milk bowl 21 and the breast collecting shield 22 are installed in the main unit component 10 as a whole.

[0041] Specifically, the milk bowl assembly 20 includes a milk bowl 21 and a milk collecting shield 22. The milk collecting shield 22 is connected to the inner surface of the milk bowl 21, and the milk collecting shield 22 and the milk bowl 21 form a milk storage space. After the milk bowl assembly 20 is installed to the host assembly 10, the milk bowl 21 is accommodated in the accommodating cavity 100, and the milk collecting shield 22 is at least partially located in the accommodating cavity 100.

[0042] In one embodiment, the side of the milk bowl 21 facing away from the first plane P is exposed through the opening of the accommodating cavity 100 of the main assembly 10, and the breast collecting shield 22 at least partially extends out of the accommodating cavity 100 and beyond the first plane P. The breast collecting shield 22 is trumpet-shaped, and a milk collecting channel 221 is formed inside. When the wearable breast pump is worn on a human breast, the breast collecting shield 22 is covered on the breast and well attached to the human body, and the nipple is located in the milk collecting channel 221. The milk collected from the breast can flow into the milk bowl 21 along the milk collecting channel 221 for storage.

[0043] It is understandable that in other embodiments, such as Figure 1B As shown, the breast collecting shield 22 may also be completely located in the accommodating cavity 100 and does not extend beyond the first plane P, that is, the opening end of the breast collecting shield 22 is flush with the first plane P or has a distance therefrom.

[0044] By providing a receiving cavity 100 that runs through the thickness direction of the main body component 10 , the milk bowl 21 and the breast shield 22 are integrated on the milk bowl component 20 , and the two can be disassembled and assembled as a whole, which is beneficial to improving the disassembly and assembly efficiency of the milk bowl 21 .

[0045] It is understandable that in other embodiments, the accommodating cavity 100 may not penetrate the thickness direction of the main assembly 10, that is, the accommodating cavity 100 is still a distance away from the first surface P. In this case, the breast collecting shield 22 and the milk bowl 21 can be assembled with the main assembly 10 as separate structural parts. Figure 1A The right side is mounted on the first surface P of the main assembly 10, and the milk bowl 21 is Figure 1A The left side of the milk bowl assembly 20 is installed in the accommodating cavity 100 of the main unit assembly 10. For another example, the milk bowl assembly 20 may also not include the breast collecting shield 22, the breast collecting shield 22 is integrally connected to the main unit assembly 10, the first surface P is located on the breast collecting shield 22, and the accommodating cavity 100 is the space on the left side of the breast collecting shield 22, and is connected to the breast collecting shield 22 after the milk bowl assembly 20 is installed in the main unit assembly 10. For another example, the milk bowl assembly 20 and the main unit assembly 10 may also include a part of the breast collecting shield 22 respectively, and when the milk bowl assembly 20 is installed in the accommodating cavity 100 of the main unit assembly 10, the two parts of the breast collecting shield 22 are spliced ​​into a complete breast collecting shield 22. For the convenience of explaining the present application, the following is an example in which the accommodating cavity 100 runs through the thickness direction of the main unit assembly 10.

[0046] Combination Figure 3 As shown, in one embodiment, the milk bowl assembly 20 also includes a deformable suction bowl 23, which is covered on one end of the inner surface of the breast shield 22 facing the milk bowl 21, and the suction bowl 23 is used to shrink and deform under the negative pressure of the main assembly 10 to transmit negative pressure.

[0047] In this embodiment, the suction cup 23 contracts in a direction close to or away from the human body, and the breast pump can be made thinner. For example, the suction cup 23 can be located on the center line X of the breast collecting shield 22, so that the suction cup 23 is opposite to one end of the milk collecting channel 221.

[0048] By setting the contraction direction of the suction cup 23 to be close to or away from the human body, after the suction cup 23 is deformed to generate negative pressure, milk can be sucked from the human body into the breast collecting shield 22, and the milk can enter the milk storage space 200 between the milk bowl 21 and the breast collecting shield 22 along the horizontal milk collecting channel 221 in the breast collecting shield 22.

[0049] In this embodiment, a negative pressure chamber Q is formed between the suction bowl 23 and the milk bowl 21. The suction bowl 23 isolates the negative pressure chamber Q of the milk bowl 21 from the breast shield 22. The left and right sides of the suction bowl 23 respectively form a milk inflow path and the negative pressure chamber Q. In this way, by utilizing the main unit component 10 to evacuate the negative pressure chamber Q, the suction bowl 23 can be driven to contract and deform into the negative pressure chamber Q, thereby generating a suction force acting on the breast.

[0050] Specifically, the breast collecting shield 22 has a milk collecting channel 221 and a milk outlet 22B, and the suction cup 23 covers both the milk collecting channel 221 and the milk outlet 22B, and a gap G is formed between the suction cup 23 and the breast collecting shield 22 to connect the milk collecting channel 221 and the milk outlet 22B. Figure 3 As shown, it is the placement orientation of the wearable breast pump when worn. It can be seen that the milk outlet 22B is configured to be located below the milk collection channel 221 during the milk collection process, and the end of the milk collection channel 221 close to the suction cup 23 can be appropriately tilted downward, so that the milk can naturally flow into the gap G between the suction bowl 23 and the breast collection shield 22 along the inclined milk collection channel 221 in the breast collection shield 22, and then flow from the gap G through the milk outlet 22B to the milk storage space 200 for storage. The milk outlet 22B can be provided with a one-way valve K, such as a duckbill valve, to achieve one-way passage of milk and prevent milk from flowing back from the milk storage space 200 to the milk collection channel 221.

[0051] In one embodiment, a negative pressure chamber Q is formed between the suction cup 23 and the milk cup 21; the main unit assembly 10 may specifically include a pump body 11 connected to the negative pressure chamber Q and a battery 12 electrically connected to the pump body 11, and the pump body 11 is configured to be located below the milk cup assembly 20 during the milk collection process to evacuate the negative pressure chamber Q. The battery 12 is electrically connected to the pump body 11 to provide electrical energy to the pump body 11, and the battery 12 may be disposed below the milk cup assembly 20 together with the pump body 11.

[0052] Of course, in other embodiments, the battery 12 may be arranged below the milk bowl assembly 20 at different times from the pump body 11. For example, the battery 12 may be arranged above, on the left side or on the right side of the milk bowl assembly 20, as long as the battery 12 is electrically connected to the pump body 11. Alternatively, in some embodiments, the battery 12 may be omitted, and the pump body 11 may be powered by an external power source.

[0053] like Figure 3 As shown, the milk bowl 21 includes a first interface 210 connected to the negative pressure chamber Q and facing the pump body 11. The pump body 11 is configured to be located below the milk bowl assembly 20 during the milk collection process and connected to the first interface 210. Exemplarily, the pump body 11 is connected to the second interface 110, and the second interface 110 is exposed to the inner wall of the accommodating cavity 100 of the main assembly 10. When the milk bowl assembly 20 is installed to the main assembly 10, the first interface 210 is connected to the second interface 110, so that the negative pressure chamber Q can be vacuumed by the pump body 11.

[0054] In one embodiment, a three-way structure (not shown) is provided between the pump body 11 and the negative pressure chamber Q, the first end of the three-way structure is connected to the pump body 11, the second end is connected to the second interface 110, and the third end is connected to the solenoid valve. The solenoid valve controls the three-way structure to selectively connect with the external atmosphere, thereby realizing pressure relief after the negative pressure chamber Q is evacuated.

[0055] Optionally, the milk outlet 22B may be disposed at a lower portion of the milk storage space 200 , that is, the milk outlet 22B is located between the milk collecting channel 221 and the pump body 11 , so as to facilitate the natural flow of milk.

[0056] In order to achieve the installation and positioning of the suction bowl 23, a flared first installation sleeve 22C is formed at one end of the inner surface of the breast shield 22 facing the milk bowl 21, and the suction bowl 23 is arranged in the negative pressure chamber Q surrounded by the first installation sleeve 22C and the milk bowl 21.

[0057] Furthermore, a second mounting sleeve 21B may be formed on the milk bowl 21, and the first mounting sleeve 22C and the second mounting sleeve 21B form a negative pressure chamber Q. For example, the second mounting sleeve 21B is convexly arranged on the inner surface of the milk bowl 21, and the edge of the suction bowl 23 is sandwiched between the first mounting sleeve 22C and the second mounting sleeve 21B.

[0058] The inner diameter of the first mounting sleeve 22C is larger than the outer diameter of the second mounting sleeve 21B. By using the first mounting sleeve 22C to cooperate with the second mounting sleeve 21B, the second mounting sleeve 21B abuts the suction bowl 23 against the expanded step surface of the first mounting sleeve 22C, which can prevent the suction bowl 23 from loosening. The first mounting sleeve 22C provides a support surface for the suction bowl 23. At the same time, the inner wall of the first mounting sleeve 22C cooperates with the outer wall of the second mounting sleeve 21B, and the folded edge of the edge of the suction bowl 23 can be clamped between the two, thereby providing a reliable sealing effect.

[0059] It is understandable that the edge of the suction bowl 23 here is clamped between the first mounting sleeve 22C and the second mounting sleeve 21B refers to the position of the edge of the suction bowl 23, and does not mean that the edge of the suction bowl 23 is fixed in this way. Optionally, the suction bowl 23 can be fixed on the first mounting sleeve 22C, or it can be fixed on the outer edge of the second mounting sleeve 21B, or it can be fixed on the first mounting sleeve 22C and the second mounting sleeve 21B at the same time. In other words, the suction bowl 23 can be fixed on the milk bowl 21, and it can form a negative pressure chamber Q with the second mounting sleeve 21B of the milk bowl 21, and then assembled with the breast collecting shield 22; the suction bowl 23 can also be fixed on the breast collecting shield 22, and when the milk bowl 21 and the breast collecting shield 22 are assembled, the suction bowl 23 and the milk bowl 21 are assembled to form a negative pressure chamber Q.

[0060] Combination Figures 2 to 4As shown, the milk bowl 21 of the present embodiment includes a top surface portion 211 and an annular portion 212, and the top surface portion 211 is connected to an end of the annular portion 212 away from the first surface P; when the milk bowl assembly 20 is installed to the main assembly 10, the milk bowl 21 is accommodated in the accommodating cavity 100, and the top surface portion 211 of the milk bowl 21 is exposed outside the main assembly 10, and the annular portion 212 of the milk bowl 21 is inserted into the accommodating cavity 100 and fits with the inner wall of the accommodating cavity 100, thereby realizing the assembly of the milk bowl assembly 20 and the main assembly 10.

[0061] In one embodiment, the top surface portion 211 of the milk bowl 21 is a curved surface, and the top surface portion 211 is farther away from the first plane P than the annular portion 212, and the annular portion 212 is connected to the inner surface of the top surface portion 211. Exemplarily, the top surface portion 211 can be set to smoothly transition with the main assembly 10. When the milk bowl assembly 20 is installed to the main assembly 10, the milk bowl 21 is seamlessly connected with the outer contour of the main assembly 10. For example, the wearable breast pump can be roughly hemispherical, achieving a more beautiful effect.

[0062] Exemplarily, the inner circumferential wall of the accommodating cavity 100 may be perpendicular to the first surface P, the annular portion 212 is also perpendicular to the first surface P, and the milk bowl assembly 20 may be installed into the accommodating cavity 100 from the side of the main assembly 10 facing away from the first surface P.

[0063] In order to limit the depth of the milk bowl assembly 20 inserted into the receiving cavity 100 of the main assembly 10, as shown in FIG. Figure 2 As shown, the outer wall of the annular portion 212 is provided with a guide rib 213 extending along the thickness direction of the main body assembly 10, and the inner wall of the accommodating cavity 100 is provided with a U-shaped limiting groove 101. The guide rib 213 is inserted into the limiting groove 101 and abuts against the end of the limiting groove 101. The extreme position of the insertion of the guide rib 213 is limited by the end of the limiting groove 101, so as to limit the depth of the milk bowl 21 inserted into the accommodating cavity 100.

[0064] It is understandable that, in other embodiments, the limiting groove 101 can also be provided on the outer wall of the annular portion 212, and the guide rib 213 can be provided on the inner wall of the accommodating cavity 100, that is, one of the outer wall of the annular portion 212 and the inner wall of the accommodating cavity 100 is convexly provided with a guide rib 213 extending along the thickness direction of the main assembly 10, and the other is provided with the limiting groove 101, and the guide rib 213 is inserted into the limiting groove 101 and abuts against the end of the limiting groove 101.

[0065] In addition, a flange 213 protruding from the annular portion 212 may be provided on the edge of the top surface portion 211 . The flange 213 abuts against the main assembly 10 and may also be used to limit the depth of the milk bowl 21 inserted into the accommodating cavity 100 .

[0066] In one embodiment, the breast collecting shield 22 may further include a first flange portion 222 and a second flange portion 223 connected to each other, and the second flange portion 223 is sealed between the first flange portion 222 and the inner wall of the milk bowl 21. Through the above arrangement, the second flange portion 223 can enhance the sealing effect between the breast collecting shield 22 and the milk bowl 21, and prevent milk from leaking from the connection between the breast collecting shield 22 and the milk bowl 21.

[0067] The first flange portion 222 and the second flange portion 223 may be integrally provided, or may be assembled from two separate structural components.

[0068] Considering that the user needs to conveniently observe the amount of milk in the milk bowl 21 in real time during use, the present embodiment can further set at least a portion of the milk bowl 21 exposed outside the main assembly 10 to be a light-transmitting material. For example, the top surface portion 211 of the milk bowl 21 is a light-transmitting material, or the entire milk bowl 21 is a light-transmitting material. It can be understood that the light-transmitting material mentioned here refers to a transparent or translucent material, and the user can observe the amount of milk in the milk bowl 21 through the milk bowl 21.

[0069] By installing the milk bowl 21 on the surface of the main unit 10 in a forward manner, the milk bowl 21 is not easily blocked by clothes, and the user can quickly evaluate the amount of milk, so that when the amount of milk in the milk bowl 21 reaches a certain amount, the user can immediately notify the breast pump to stop working.

[0070] In summary, on the one hand, the present application installs the milk bowl assembly 20 into the accommodating cavity 100 of the main body assembly 10, so that the main body assembly 10 can be used as a gripping shell of the breast pump to avoid accidental separation of the milk bowl assembly 20 and the main body assembly 10 due to simultaneous gripping of the milk bowl assembly 20 and the main body assembly 10; on the other hand, the present application installs the milk bowl 21 in a front-placed manner on the surface of the main body assembly 10, and sets at least a part of the milk bowl 21 to a light-transmitting material, so that the user can observe the amount of milk in the milk bowl 21 at any time to avoid milk overflow.

[0071] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
