[0028] like Figure 1 As shown in Figure 6, this utility model provides a wearable breast pump that is easy to assemble and disassemble, including a milk bowl shell 1 and a breast pumping unit 2 for providing a negative pressure source. The milk bowl shell 1 includes a detachably connected front shell 11 and a rear shell 12. The breast pumping unit 2 is slidably connected to the front shell 11. The front shell 11 has a first mounting cavity 103 for installing the breast pumping unit 2. In this embodiment, the breast pumping unit 2 is slidably installed in the first mounting cavity 103. The breast pumping unit 2 can slide along the mounting cavity relative to the milk bowl shell 1 under force, thus realizing the assembly and disassembly of the breast pumping unit 2 in the milk bowl shell 1. In this embodiment, the breast pumping unit 2 does not require additional assembly structure alignment or additional accessory connections during installation, which greatly reduces the difficulty of assembling and disassembling the breast pumping unit 2 and improves the user's ability to assemble and disassemble it independently. The convenience of the breast pump unit 2, especially the frequent cleaning of the milk bowl shell 1 during daily use of the wearable breast pump, is a key advantage. Since the milk bowl shell 1 is connected to the breast pump unit 2, cleaning requires separating the two parts to facilitate cleaning the milk bowl shell 1 and protect the breast pump unit 2 from water damage. This embodiment improves the assembly structure of the breast pump unit 2, making it easier for users to assemble and disassemble the unit. This adapts the wearable breast pump to the frequent cleaning of the milk bowl shell 1, enhancing the user experience. Furthermore, the breast pump unit 2 is housed in the first mounting cavity 103 within the milk bowl shell 1, reducing the overall size of the wearable breast pump, improving its portability, and making it convenient for users to use when out and about, while also increasing user comfort.

[0029] Specifically, such as Figure 1 As shown in Figure 6, the breast pump 2 includes a main housing 21 slidably connected to the front shell 11 of the milk bowl and a receiving cavity 22 disposed in the main housing 21. The receiving cavity 22 is used to accommodate a negative pressure device. At least a portion of the main housing 21 protrudes outside the first mounting cavity 103. The protruding portion of the main housing 21 relative to the first mounting cavity 103 can be gripped by the user to facilitate manual disassembly and assembly of the breast pump 2.

[0030] Furthermore, such as Figure 1As shown in Figure 6, a milk storage cavity 101 is provided between the front shell 11 and the rear shell 12 of the milk bowl. The rear shell 12 of the milk bowl is provided with a milk pouring port 102 communicating with the milk storage cavity 101. The milk bowl shell 1 can receive breast milk expressed by the breast pump through the milk storage cavity 101 and pour out breast milk through the milk pouring port 102. The front shell 11 of the milk bowl is also provided with a second mounting cavity 104 for installing the breast pump cover 3 and an extension shell 13 extending into the milk storage cavity 101. The first mounting cavity 103 and the second mounting cavity 104 are arranged vertically within the extension shell 13, and a partition 131 is provided between the first mounting cavity 103 and the second mounting cavity 104. In this embodiment, the first mounting cavity 104 is isolated by the extension shell 13. 03. The second mounting cavity 104 and the milk storage cavity 101 are separated by the partition 131 inside the extended housing 13. The partition 131 serves as the bottom of the first mounting cavity 103 and the top of the second mounting cavity 104, which helps to simplify the structure of the front shell 11 of the milk bowl. While ensuring that the overall volume of the breast pump is small, it can increase the space of the first mounting cavity 103, the second mounting cavity 104 and the milk storage cavity 101. Furthermore, by setting the partition 131 inside the extended housing 13 to directly form the first mounting cavity 103 and the second mounting cavity 104 arranged vertically, it helps to reduce the cleaning dead corners of the front shell 11 of the milk bowl, thereby making the front shell 11 of the milk bowl easier to clean.

[0031] Furthermore, the first mounting cavity 103 and the second mounting cavity 104 extend toward the milk storage cavity 101, and the extension direction of the first mounting cavity 103 is parallel to the extension direction of the second mounting cavity 104. The installation direction of the breast pump 2 is a parallel sliding installation in the milk bowl shell 1, which makes the connection between the breast pump 2 and the milk bowl shell 1 more intuitive. Users can easily slide the breast pump 2 into the milk bowl shell 1 without complicated operations or alignment steps, and can quickly complete the installation of the breast pump 2, saving time. Moreover, the breast pump 2 is tightly connected to the milk bowl shell 1, and the breast pump 2 is not easy to slide or fall off during use, improving the stability of the wearable breast pump. In addition, the bra 3 is installed in the second mounting cavity 104. The bra 3 can at least partially abut against the main shell 21 and form an anti-detachment structure 311. The anti-detachment structure 311 is used to restrict the main shell 21 from falling off. The installation cavity is provided. During assembly, the breast pump 2 can be installed in the first installation cavity 103 of the front shell 11 of the milk bowl first, and then the breast shield 3 can be installed in the installation cavity. Since the breast shield 3 is provided with a fitting part 31 that expands outward in a radial direction, the breast shield 3 is opposite to the breast pump 2 and located on the front side of the breast pump 2. The outer wall of the breast shield 3 forms an anti-detachment structure 311 to prevent the breast pump 2 from detaching from the installation cavity. There is no need to set an additional anti-detachment structure 311, which helps to simplify the structure of the breast pump. At the same time, it makes the main shell 21 fit tightly with the inner wall of the installation cavity, improving the connection stability of the breast pump 2. Of course, the main shell 21 and the inner wall of the first installation cavity 103 can be provided with a snap-fit ​​structure as the anti-detachment structure 311 of the breast pump 2. The user can apply an appropriate pulling force to the breast pump 2 to pull it out of the installation cavity. This embodiment does not make specific limitations.

[0032] In other alternative embodiments, such as Figure 5As shown, a limiting shell 23 is also provided on one side of the main shell 21, and the receiving cavity 22 extends into the limiting shell 23, which is beneficial to increasing the installation space of the negative pressure device. The limiting shell 23 is at least partially located outside the first mounting cavity 103. A limiting wall 24 is provided between the limiting shell 23 and the main shell 21, and the limiting wall 24 abuts against the front shell 11 and the rear shell 12 of the milk bowl. The front shell 11 of the milk bowl is also provided with a clearance opening 1031 communicating with the first mounting cavity 103, and at least a portion of the outer wall of the limiting shell 23 is embedded in the clearance opening 1031. In this embodiment, the first mounting cavity 103 is located at the top of the front shell 11 of the milk bowl, and the... The top of the first mounting cavity 103 is provided with a relief opening 1031 that connects to the outside of the breast pump. The limiting housing 23 protrudes outside the front shell of the milk bowl 11 through the relief opening 1031, which is beneficial for providing a gripping fulcrum for the user to manually disassemble the breast pump 2, making it convenient for the user to disassemble and assemble the breast pump 2. During assembly, the limiting housing 23 abuts against the rear shell of the milk bowl 12 and the front shell of the milk bowl 11 through the limiting wall 24, which is beneficial for improving the connection stability and tightness between the breast pump 2 and the milk bowl housing 1, thereby improving the stability of the breast pump in use. At least part of the outer wall of the limiting housing 23 is embedded in the relief opening 1031, so that the front side of the front shell of the milk bowl 11 forms a flat end face, which is beneficial for installing the bra 3.

[0033] In other alternative embodiments, such as Figure 6 As shown, the bottom of the limiting housing 23 is provided with an inclined wall 25 connected to the main housing 21. The bottom of the first mounting cavity 103 extends away from the rear shell 12 of the milk bowl. A handle position 251 is formed between the inclined wall 25 and the bottom of the first mounting cavity 103. In this embodiment, the inclined wall 25 located at the bottom is provided between the limiting housing 23 and the main housing 21. A handle position 251 is formed between the inclined wall 25 and the bottom wall 212 of the first mounting cavity 103. The handle position 251 allows the user to manually disassemble the breast pump 2. The fulcrum provides a gripping point, making it easy for users to assemble and disassemble the breast pump 2. Furthermore, it eliminates the need for an additional handle 251 on the outer wall of the limiting housing 23, thus reducing the size of the breast pump and improving its portability and wearing comfort. Optionally, the inclined wall 25 is configured as an arc-shaped wall protruding towards the receiving cavity 22. The connection between the periphery of the inclined wall 25 and the main housing 21 and the limiting housing 23 is also via an arc-shaped segment, which optimizes the user's tactile experience and prevents the sharp edges of the inclined wall 25 from scratching the user.

[0034] In other alternative embodiments, such as Figure 6As shown, the main housing 21 includes a side wall 211 opposite to the limiting housing 23 and a bottom wall 212 connected to the side wall 211. The side wall 211 is at least partially configured as an arc-shaped wall. The arc-shaped wall in the main housing 21 can expand the volume of the receiving cavity 22 and better install the negative pressure device. The bottom wall 212 communicates with the first opening 2121 of the receiving cavity 22. Since the negative pressure device is installed in the receiving cavity 22, the first opening 2121 can communicate with the negative pressure channel in the negative pressure device to transmit negative pressure to the second mounting cavity 104.

[0035] In some alternative embodiments, the front shell 11 and the rear shell 12 of the milk bowl are configured for rotational assembly. The front shell 11 and the rear shell 12 are provided with compatible rotational assembly structures. The forces on the front shell 11 and the rear shell 12 can be helically connected through this rotational assembly structure. Users can easily disassemble and assemble the milk bowl 1 by rotating the front shell 11 and the rear shell 12, greatly reducing the difficulty of disassembling and assembling the milk bowl 1 and making it easier for users to disassemble and assemble the milk bowl 1. Furthermore, the helical rotation between the front shell 11 and the rear shell 12 can be converted into axial displacement to improve the tightness of the connection between the front shell 11 and the rear shell 12, which helps prevent milk leakage. Optionally, the rotational assembly structure can be configured as a meshing threaded structure, or as two compatible inclined surfaces, or as a compatible snap-fit ​​block and a rotating groove. In this embodiment, the structure is not specifically limited. Preferably, the longitudinal section of the relative rotation surface between the front and rear shells of the milk bowl 11 is circular to facilitate the rotational assembly of the two. The milk bowl shell 1 is generally set as a hemisphere or a near-hemisphere, which helps to increase the volume of the milk storage chamber 101, increase the milk storage capacity of the breast pump, and at the same time reduce the overall volume of the breast pump, improving the portability and wearing comfort of the breast pump. On the other hand, since the front and rear shells of the milk bowl 11 are spirally connected by a rotational assembly structure, the side of the extension shell 13 facing the rear shell 12 is set as a curved wall. This curved wall is adapted to the rear shell 12. During the relative rotation of the front and rear shells of the milk bowl 11, the front shell 11 drives the extension shell 13 to rotate relative to the rear shell 12, so as to ensure the disassembly and normal use of the milk bowl shell 1.

[0036] In other alternative embodiments, such as Figure 6As shown, the partition 131 has a second opening 132 communicating with the first mounting cavity 103 and the second mounting cavity 104. The partition 131 abuts against the bottom wall 212 and is located at the lower part of the bottom wall 212. The second opening 132 corresponds to the first opening 2121. When the user installs the breast pump 2, the breast pump 2 is pushed into the first mounting cavity 103, and the first opening 2121 and the second opening 132 automatically align, so that the negative pressure channel communicates with the second mounting cavity 104, thereby driving the breast shield 3 to produce elastic deformation to simulate the sucking action of an infant. In this embodiment, the breast shield 3 is equipped with an integrally formed three-way component. The breast shield 3 includes a fitting part 31, a milk outlet part 32, and a milk suction part 33 connected in sequence. The milk suction part 33 has a milk suction cavity 331 on its inner side. The milk outlet part 32 has a connection between the milk suction cavity 331 and the milk storage cavity 101. The milk outlet 321 has a one-way milk outlet channel. The bottom of the extended housing 13 has a through-hole, through which the milk outlet part 32 can pass, so that the one-way milk outlet channel 321 communicates with the milk storage chamber 101. The milk suction part 33 is set as a flexible diaphragm 332 that can be elastically deformed. The flexible diaphragm 332 and the extended housing 13 enclose a negative pressure chamber 1041. The milk suction host 2 generates negative pressure in the negative pressure chamber 1041, thereby driving the flexible diaphragm 332 to expand and deform, further generating negative pressure in the milk suction chamber 331, so as to realize the simulation of the baby's sucking action and milk suction, and the milk is unidirectionally transported to the milk storage chamber 101 through the one-way milk outlet channel 321. The milk bowl front shell 11 in this embodiment has a simple structure layout, which is easy to implement and helps to reduce production costs. It should be noted that the milk outlet part 32 and the milk suction part 33 in this embodiment are integrated into the breast shield 3, which simplifies the structure of the milk bowl front shell 11.

[0037] The above examples are merely illustrative of the technical content of this utility model to facilitate reader understanding, but do not imply that the implementation of this utility model is limited to these embodiments. Any technical extensions or re-creations made based on this utility model are protected by this utility model. The scope of protection of this utility model is defined by the claims.
