Description

Breast pump [Technical Field]

[0001] This application relates to the technical field of breastfeeding products, specifically to a breast pump. [Background Technology]

[0002] A breast pump is a device used to help users express breast milk from their breasts. The breast is a very sensitive part of the body. The breast pump works by creating negative pressure inside, thus drawing out and storing the milk. Scientific data and practical experience show that applying heat during pumping has a significant effect on increasing milk production, relieving blocked milk ducts, and reducing breastfeeding pain. When the ambient temperature is low, if the breast is in direct contact with the breast pump, it can easily create a strong feeling of coldness, causing discomfort and potentially reducing milk production. Therefore, users often try to warm the breast pump cups before using it, usually by soaking or steaming them in hot water. However, this method is not only cumbersome, but the temperature of the cups is also difficult to maintain. After using the breast pump for a certain period, the temperature of the cups drops rapidly and continuously, especially in colder winter months. [Summary of the Invention]

[0036] This application provides a breast pump. Please refer to Figures 1 and 2 together. The breast pump includes a bottle 10, a suction component 20, and a main unit 30. The bottle 10 is provided with a milk storage chamber 101. The suction component 20 includes a guide tube 210 and a horn cover 220 connected to the guide tube 210, the outer diameter of which gradually increases in the direction away from the guide tube 210. The horn cover 220 is connected to the milk storage chamber 101 through the guide tube 210 and is provided with a heating element 230. The main unit 30 is connected between the bottle 10 and the guide tube 210. The main unit 30 is used to generate negative pressure in the milk storage chamber 101 to draw milk. The main unit 30 is electrically connected to the heating element 230.

[0037] Currently, breastfeeding mothers use hot towels, heating pads, or heated massage devices to apply heat to the breasts while pumping. However, this approach has shortcomings in terms of both effectiveness and convenience: First, when using a breast pump, the breasts are already surrounded by the pump's cups, limiting the area that the hot towel, heating pad, or heated device can reach. It can only provide heat to the outer edge of the breast or a fixed location, significantly reducing its effectiveness. Second, the heat from the hot towel and heating pad lasts for less than two minutes, and the temperature drops quickly. Furthermore, placing another item (hot towel, massage device) on the breast while using a breast pump makes the already strenuous task of pumping even more cumbersome. In use, the breast pump of this application has a speaker cover 220 that fits against the breast to draw in milk. The heating element 230, powered by the main unit, heats the area of ​​the speaker cover 220 that contacts the breast, thereby improving the user's comfort during the pumping process. The speaker cover 220 continuously heats up, preventing the breast from feeling cold and causing discomfort, thus avoiding reduced milk production due to breast discomfort. Simultaneously, the milk drawn in by the speaker cover 220 flows through the guide tube 210 into the milk storage chamber 101. The independently designed bottle 10 can be easily detached from the breast pump for convenient milk storage and transfer.

[0038] Specifically, the material of the baby bottle 10 can be glass, plastic, or silicone, and the material of the baby bottle 10 needs to meet the corresponding food safety standards. In some embodiments, the baby bottle 10 needs to be sterilized by boiling in hot water during cleaning; therefore, the material of the baby bottle 10 can also be a heat-resistant material.

[0039] Optionally, the suction member 20 includes a first suction member 240 and a second suction member 250 located on the side of the first suction member 240 facing away from the main unit 30. The heating member 230 is located between the first suction member 240 and the second suction member 250. The first suction member 240 and the second suction member 250 are fixedly connected, and the materials of the first suction member 240 and the second suction member 250 are different. The first suction member 240 is in contact with the main unit 30, and the second suction member 250 is in contact with the user. The first suction member 240 may include a three-way structure, using the negative pressure generated by the main unit 30 in the milk storage chamber 101 to draw milk from the breast and guide the milk into the milk storage chamber 101.

[0040] Furthermore, the first absorbent component 240 can be made of hard plastic to provide some support for the second absorbent component 250, while also facilitating the positioning and fixation of the entire absorbent component 20 to the main unit 30. The second absorbent component 250 can be made of either soft or hard plastic as needed. Specifically, the second absorbent component 250 can be made of soft plastic to ensure that it can cover the breast well without causing harm. Both the first absorbent component 240 and the second absorbent component 250 need to meet the corresponding food safety and high-temperature resistance standards.

[0041] In some embodiments, the first absorbent member 240 may be solid silicone, and the second absorbent member 250 may be liquid silicone. In some embodiments, the first absorbent member 240 and the second absorbent member 250 may both be made of soft silicone or both of hard silicone. In other embodiments, the first absorbent member 240 may be composed of a portion of hard silicone and a portion of soft silicone. Further, the first absorbent member 240 and the second absorbent member 250 may be fixed together by means of bonding, snap-fitting, screw connection, or other methods.

[0042] Further, as shown in Figures 3 and 4, the main unit 30 includes a housing 310, which is connected between the liquid suction member 20 and the baby bottle 10. The housing 310 has an installation groove 3101 in which the liquid suction member 20 is inserted.

[0043] Optionally, the heating element 230 may include a carrier plate 231 and an electric heating element 232, with the electric heating element 232 fixed to the carrier plate 231. The carrier plate 231 may be a mica sheet, the electric heating element 232 may be a resistance heating wire, and the heating element 230 may be an electric heating plate, which is an electric heating device in which a resistance heating wire is wound around a mica plate (mica sheet). The electric heating plate utilizes the excellent insulation and high-temperature resistance of mica sheets. It uses mica sheets as a skeleton and insulation layer, supplemented by galvanized steel or stainless steel plates for support and protection, and can be made into various shapes such as plate, sheet, cylindrical, conical, tubular, and circular heating devices. In other embodiments, the heating element 230 may also be a ceramic heating element, a silicon conductive heating element, a silicone heating element, an aluminum foil heating element, etc.

[0044] In some embodiments, the heating element 230 may be located between the first liquid absorber 240 and the second liquid absorber 250. For example, the heating element 230 may be attached to the surface of the second liquid absorber 250 near the first liquid absorber 240, and when the first liquid absorber 240 and the second liquid absorber 250 are fixedly connected, the heating element 230 may be pressed and fixed between the first liquid absorber 240 and the second liquid absorber 250.

[0045] In some embodiments, the heating element 230 may be embedded in the second liquid-absorbing element 250, and the heating element 230 may be fixedly connected to the second liquid-absorbing element 250 by injection molding.

[0046] Specifically, the heating element 230 can be annular in shape, surrounding the liquid guide tube 210 and fixed to the horn cover 220. The electric heating element 232 can extend spirally around the contour of the horn cover 220.

[0047] Optionally, a temperature sensor 280 is provided on the speaker cover 220, and the temperature sensor 280 can be mounted on the carrier plate 231. As shown in Figures 2 and 5, the heating element 230 is connected to a first conductive element 270, and the main unit 30 is provided with a second conductive element 320. The first conductive element 270 and the second conductive element 320 are electrically connected.

[0048] Furthermore, there are three first conductive elements 270, which are used to electrically connect the temperature sensor 280 and the heating element 230. The temperature sensor 280 can be a semiconductor device (with positive and negative polarities) or a thermistor (without polarity). One electrode of the temperature sensor 280 and one electrode of the heating element 230 are simultaneously electrically connected to the same first conductive element 270. Specifically, the three first conductive elements 270 can be arranged side by side. The left and right first conductive elements 270 are respectively connected to the positive and negative terminals of the heating element 232, and the middle first conductive element 270 is connected to the negative terminal of the heating element 232 through the temperature sensor 280 to form a circuit. The temperature sensor 280 is used to monitor the temperature of the heating element 230 in real time. In some other embodiments, there can be multiple first conductive elements 270, for example, there can be four first conductive elements 270, corresponding to the positive and negative terminals of the temperature sensor 280 and the heating element 232.

[0049] Furthermore, the first conductive element 270 can be cylindrical in shape, the first liquid-absorbing element 240 includes a first horn cover 244, the second liquid-absorbing element 250 can include a second horn cover 252, and the heating element 230 is located between the first horn cover 244 and the second horn cover 252. The first conductive element 270 protrudes from the heating element 230 on the side facing the first horn cover 244. A corresponding positioning hole 2403 can be provided on the first horn cover 244, and the first conductive element 270 can be inserted into the positioning hole 2403, electrically connected to the second conductive element 320 of the main unit 30 through the positioning hole 2403. In some embodiments, the first conductive element 270 can also pass through the positioning hole 2403 and contact the second conductive element 320 to form an electrical connection. The number of positioning holes 2403 can correspond to the number of first conductive elements 270. The number of second conductive elements 320 can correspond to the number of first conductive elements 270. The second conductive element 320 can be a pogo pin. A pogo pin is a precision connector used in electronic products such as mobile phones. Pogo pins are widely used in various electronic products and serve as signal transmission connectors.

[0050] Furthermore, the main unit 30 includes a battery 330 disposed within the housing 310. The battery 330 is electrically connected to the second conductive element 320. The first conductive element 270 can abut against the second conductive element 320, so that the battery 330 can supply power to the heating element 230. The heating element 230 can be completely sealed within the suction element 20 by the cover of the first suction element 240 and the second suction element 250, so that it does not come into direct contact with the human body and breast milk. The temperature sensor 280 can measure the temperature of the suction element 20 multiple times per second and transmit the temperature information directly to the microprocessor (not shown in the figure) of the main unit 30. The microprocessor intelligently adjusts the heating element 230, and by adjusting the heating power of the heating element 230, the temperature of the speaker cover 220 can be maintained within a suitable range, so that the user can pump breast milk at the safest and most comfortable temperature. For example, when the temperature is cold, the microprocessor can increase the heating power of the heating element 230 to raise the temperature of the speaker cover 220; when the temperature is hot, the microprocessor can reduce the heating power of the heating element 230 or stop the heating element 230 from working to keep the temperature of the speaker cover 220 suitable. Users can also set a preset temperature according to their own usage experience, and the microprocessor can intelligently adjust to keep the speaker cover 220 at the preset temperature or within a preset temperature range.

[0051] Optionally, referring to Figures 6 to 8, in some embodiments, the suction member 20 includes a first suction member 240 and a suction assembly 200 located on the side of the first suction member 240 opposite to the main unit 30. The suction assembly 200 and the first suction member 240 are detachably connected. The heating element 230 is fixedly connected to the suction assembly 200. The materials of the first suction member 240 and the suction assembly 200 are different. The suction assembly 200 can be installed on the first suction member 240 and fixedly connected to it, so that the breast pump can draw milk through the suction assembly 200. The suction assembly 200 can also be disassembled and separated from the first suction member 240 for cleaning, or the suction assembly 200 can be disassembled and replaced.

[0052] In some embodiments, the liquid absorption assembly 200 and the first liquid absorption member 240 can be detachably connected by means of snap-fit ​​connection, threaded connection, magnetic connection, etc. For example, magnetic members can be fixed to the liquid absorption assembly 200 and the first liquid absorption member 240 respectively, and the detachable connection between the liquid absorption assembly 200 and the first liquid absorption member 240 can be achieved by the magnetic attraction between the magnetic members. The magnetic members can be magnets or metal.

[0053] Specifically, the first liquid-absorbing element 240 can be made of hard plastic, while the liquid-absorbing assembly 200 can be made of soft plastic. The heating element 230 is disposed inside the liquid-absorbing assembly 200.

[0054] Furthermore, the liquid absorption assembly 200 includes a second liquid absorption member 250 and a third liquid absorption member 260 fixedly connected. The third liquid absorption member 260 is located between the first liquid absorption member 240 and the second liquid absorption member 250, and the heating member 230 is located between the third liquid absorption member 260 and the second liquid absorption member 250. The second liquid absorption member 250 and the third liquid absorption member 260 are fixedly connected.

[0055] In some embodiments, the heating element 230 may be attached to the surface of the second liquid absorber 250 facing the third liquid absorber 260, and when the third liquid absorber 260 and the second liquid absorber 250 are fixedly connected, it is pressed and fixed between the third liquid absorber 260 and the second liquid absorber 250.

[0056] In some embodiments, the second liquid-absorbing member 250 and the third liquid-absorbing member 260 can be connected by a secondary injection molding process. The heating member 230 can be embedded between the second liquid-absorbing member 250 and the third liquid-absorbing member 260, or it can be embedded within the second liquid-absorbing member 250 or the third liquid-absorbing member 260. Secondary injection molding is a process in which a certain plastic raw material is molded in a primary plastic mold, the molded part is removed, and then placed into a secondary molding mold to be injected again with the same or another type of plastic material.

[0057] Furthermore, the third liquid-absorbing component 260 can be made of a soft rubber material, such as silicone. The third liquid-absorbing component 260 and the second liquid-absorbing component 250 can be made of the same material. The second liquid-absorbing component 250 and the third liquid-absorbing component 260 can be fixed together by double-injection hydraulic molding, with the heating element 230 encased between the second liquid-absorbing component 250 and the third liquid-absorbing component 260. The detachable connection structure between the liquid-absorbing assembly 200 and the first liquid-absorbing component 240 facilitates the replacement of the liquid-absorbing assembly 200, which is in direct contact with the human body, improving the reusability of the first liquid-absorbing component 240. It also facilitates the separate fabrication of massage structures on the liquid-absorbing assembly 200.

[0058] Optionally, as shown in Figures 7 and 13, the breast pump further includes a conductive component 70. The conductive component 70 includes a first conductive element 270 connected to the heating element 230 and a second conductive element 320 disposed on the main unit 30. The first suction element 240 is provided with a limiting hole 2401, which is used for electrical connection between the first conductive element 270 and the second conductive element 320. The conductive component 70 is inserted into the limiting hole 2401. The electrical connection structure between the first conductive element 270 and the second conductive element 320 can be varied. For example, the first conductive element 270 can pass through the limiting hole 2401 to be electrically connected to the second conductive element 320, or the second conductive element 320 can pass through the limiting hole 2401 to be electrically connected to the first conductive element 270, or both the first conductive element 270 and the second conductive element 320 can be inserted into the limiting hole 2401 and abut against each other within the limiting hole 2401.

In some embodiments, the connector 261 may be provided with a conductive through hole 2601, into which the conductive component 70 is inserted. The connector 261 can assist in the electrical connection between the first conductive component 270 and the second conductive component 320, making the electrical connection more stable and reliable.

[0061] In some embodiments, the connector 261 may be connected to the third liquid-absorbing member 260, and the first conductive member 270 or the second conductive member 320 may be inserted into the conductive through-hole 2601. The first conductive member 270 may be columnar, and the second conductive member 320 may be contact-shaped. The first conductive member 270 may pass through the conductive through-hole 2601 and abut against the second conductive member 320. Alternatively, the second conductive member 320 may also be columnar, and both the first conductive member 270 and the second conductive member 320 may be inserted into the conductive through-hole 2601 and abut against each other within the conductive through-hole 2601 to form an electrical connection. Alternatively, the first conductive member 270 may be contact-shaped, and the second conductive member 320 may pass through the conductive through-hole 2601 and abut against the first conductive member 270.

[0062] In some other embodiments, the connector 261 can be connected to the host 30, and the shape and connection method of the first conductive element 270 and the second conductive element 320 can be similar to those in the above embodiments, which will not be described in detail here.

[0063] Furthermore, the first liquid suction member 240 is provided with a locking part 241, which surrounds the limiting hole 2401. The connector 261 is provided with a limiting groove 2602, and the connector 261 is inserted into the limiting hole 2401. The locking part 241 and the limiting groove 2602 form a locking engagement, and the locking part 241 and the connector 261 are sealed together, so that the connector 261 can be relatively fixed with the first liquid suction member 240. At the same time, it can prevent liquid from seeping between the first liquid suction member 240 and the liquid suction assembly 200 and coming into contact with the heating element 230 or the conductive component 70, thereby improving the reliability of the breast pump.

[0064] Furthermore, the connector 261 may protrude from the side of the third liquid-absorbing member 260 facing the first liquid-absorbing member 240. The connector 261 may be approximately frustum-shaped. The first conductive member 270 may be cylindrical, and the conductive through-hole 2601 may also be cylindrical. The first conductive member 270 may be fixed to the heating member 230 by fixing screws 271 and embedded in the conductive through-hole 2601. Specifically, the third liquid-absorbing member 260 and the connector 261 may be an integral structure, and the third liquid-absorbing member 260 and the connector 261 may be integrally injection molded. In some other embodiments, the connector 261 and the first conductive member 270 may also be fixed together by injection molding.

[0065] Furthermore, the number of limiting holes 2401 can be one, the second conductive element 320 can be located on the side of the housing 310 facing the liquid-absorbing element 20, the first conductive element 270 can be disposed on the horn cover 220, and the second conductive element 320 can be disposed close to the mounting groove 3101 to abut against the first conductive element 270 on the horn cover 220. In some other embodiments, the first conductive element 270 can also be disposed on the liquid guiding tube 210, and the second conductive element 320 can be disposed in the mounting groove 3101 to abut against the first conductive element 270 on the liquid guiding tube 210. The position of the second conductive element 320 on the main unit 30 can be arranged according to the structure and can be located at any position on the main unit 30 that can stably contact the first conductive element 270.

[0066] Optionally, the limiting groove 2602 is provided with a sealing portion 262 surrounding the connector 261. The sealing portion 262 is annular and abuts against the locking portion 241 and the connector 261 to improve the sealing performance of the connection between the connector 261 and the first liquid-absorbing member 240 and prevent liquid seepage. The sealing portion 262 and the connector 261 can be integrally injection molded.

[0067] Furthermore, the limiting groove 2602 has a first guide angle 263 on the side away from the heating element 230, and the locking part 241 has a second guide angle 242. The first guide angle 263 and the second guide angle 242 can cooperate to facilitate the insertion of the connector 261 into the limiting hole 2401. Specifically, the limiting groove 2602 has a limiting edge 264 on the side away from the heating element 230. The limiting edge 264 is used to engage with the locking part 241 to fix the connector 261, ensuring sufficient pressure during the process of the second conductive element 320 abutting against the first conductive element 270, while preventing the connector 261 from being pushed out by the second conductive element 320 and causing poor contact.

[0068] Furthermore, the first guide angle 263 is located on the side of the limiting edge 264 away from the heating element 230, and the second guide angle 242 is located on the side of the locking portion 241 near the heating element 230. The first guide angle 263 is configured to slide relative to the second guide angle 242 when the connector 261 is inserted into the limiting hole 2401, so that the end of the connector 261 away from the heating element 230 is squeezed into the limiting hole 2401. The first guide angle 263 may have an inclined surface, and the second guide angle 242 has a corresponding inclined surface. When the liquid suction assembly 200 is installed to the first liquid suction element 240, the first guide angle 263 can abut against the second guide angle 242 and slide along the inclined surface, so that the connector 261 is inserted into the limiting hole 2401, and the locking portion 241 and the limiting groove 2602 form a locking engagement.

[0069] Optionally, as shown in FIG7, the first liquid-absorbing component 240 includes a first liquid-guiding tube 243 and a first horn cover 244 connected to one end of the first liquid-guiding tube 243. The liquid-absorbing assembly 200 includes a second liquid-guiding tube 251 and a second horn cover 252 connected to one end of the second liquid-guiding tube 251. The second liquid-guiding tube 251 is inserted into the first liquid-guiding tube 243. The second liquid-guiding tube 251 is surrounded by a sealing ring 2511, which abuts against the second liquid-guiding tube 251 and the first liquid-guiding tube 243.

[0070] Specifically, the second liquid-absorbing member 250 includes a second liquid-guiding tube 251 and a second horn cover 252 connected to one end of the second liquid-guiding tube 251. The third liquid-absorbing member 260 may be annular and fixed to the side of the second horn cover 252 near the first liquid-absorbing member 240. In some other embodiments, the third liquid-absorbing member 260 may also include a second liquid-guiding tube 251 and a second horn cover 252, with the second liquid-absorbing member 250 fixed to the side of the second horn cover 252 opposite to the first liquid-absorbing member 240.

[0071] Furthermore, the sealing ring 2511 is fixedly connected to the second liquid guide tube 251, and the sealing ring 2511 and the second liquid guide tube 251 can be integrally injection molded. The sealing ring 2511 can be disposed at the end of the second liquid guide tube 251 away from the second horn cover 252. In some other embodiments, the sealing ring 2511 can also be located in the middle of the second liquid guide tube 251 or at the end near the second horn cover 252.

[0072] Furthermore, the third suction member 260 is fixed to the second horn cover 252. The third suction member 260 can be annular and can surround the second liquid guide tube 251, covering the heating element 230. The first horn cover 244, the third suction member 260, the heating element 230, and the second horn cover 252 can be stacked sequentially. The sealing ring 2511 is used to seal the connection gap between the first liquid guide tube 243 and the second liquid guide tube 251 to ensure that breast milk does not leak when it flows into the bottle 10 through the three-way structure of the suction member 20 during the breastfeeding process.

[0073] Optionally, as shown in Figure 11, the second horn cover 252 is provided with a flange 2521, which forms a limiting groove 2501. The first horn cover 244 is provided with a snap-fit ​​section 2441, which is inserted into the limiting groove 2501, and the snap-fit ​​section 2441 and the limiting groove 2501 form a snap-fit ​​engagement. The flange 2521 can be located at the edge of the second horn cover 252 away from the second liquid guide tube 251 and is arranged around the second horn cover 252. The flange 2521 is bent towards the main unit 30 to form the limiting groove 2501. The snap-fit ​​section 2441 can be located at the edge of the first horn cover 244 and can be inserted into the limiting groove 2501, forming a snap-fit ​​engagement with the limiting groove 2501. The snap-fit ​​section 2441 and the flange 2521 are sealed together.

[0074] Specifically, the snap-fit ​​segment 2441 can be embedded in the limiting groove 2501, and the snap-fit ​​segment 2441 abuts against the flange 2521 to fix the first horn cover 244 and the second horn cover 252 relative to each other, while making the snap-fit ​​segment 2441 and the flange 2521 sealed to prevent liquid from seeping into the first liquid-absorbing member 240 and the liquid-absorbing assembly 200.

[0075] Furthermore, the liquid absorption assembly 200 and the first liquid absorption member 240 can be detachably connected via structures such as the flange 2521 and the connector 261. In some embodiments, an external force can be applied to the liquid absorption assembly 200 to deform it, thereby causing the liquid absorption assembly 200 and the first liquid absorption member 240 to form a snap-fit ​​engagement, or to release the snap-fit ​​engagement between the liquid absorption assembly 200 and the first liquid absorption member 240. In other embodiments, a detachable connection between the liquid absorption assembly 200 and the first liquid absorption member 240 can also be achieved through a stable fixing structure such as magnetic attraction.

[0076] Optionally, the second horn cover 252 facing the first horn cover 244 may have a first groove 2502 for accommodating the third liquid-absorbing member 260, and the bottom of the first groove 2502 may have a second groove 2503 for accommodating the heating member 230. The third liquid-absorbing member 260 is disposed on the second groove 2503, and the first horn cover 244 is disposed on the first groove 2502. The heating member 230 may be fixed in the second groove 2503 by means of adhesive or the like, and the third liquid-absorbing member 260 may also be fixed in the first groove 2502 by means of adhesive or the like. Further, the third liquid-absorbing member 260, the heating member 230, and the second liquid-absorbing member 250 may also be fixedly connected by injection molding.

[0077] Optionally, as shown in Figure 6, the bottle 10 has a bottle cap 40 at its opening, and a one-way valve 50 is installed on the bottle cap 40. The liquid guide tube 210 is connected to the milk storage chamber 101 through the one-way valve 50. The suction member 20 has a mounting part 245, and the mounting part 245 is equipped with an elastic cavity 60. The elastic cavity 60 is used to generate negative pressure in the suction member 20 through its own deformation. The elastic cavity 60 can be connected to the mounting part 245, and the mounting part 245 can be connected to the horn cover 220 through the liquid guide tube 210. The elastic cavity 60 can be installed above the suction member 20, and the suction member 20 and the main unit 30 are fixedly positioned to ensure that the elastic cavity 60 and the main unit 30 are sealed, thereby realizing the negative pressure transmission function.

[0078] Furthermore, the mounting part 245 is connected to the first liquid guide tube 243. The first liquid suction member 240 includes the first liquid guide tube 243, the first horn cover 244 and the mounting part 245. The first liquid suction member 240 can be an integral structure, and the first liquid suction member 240 can be integrally injection molded.

[0079] Specifically, the bottle cap 40 can be fixed to the mouth of the bottle 10 by means of threaded connection, snap-fit ​​connection, or other connection methods. As shown in Figure 9, the first liquid guide tube 243 can have a liquid outlet 2402, which is connected to the one-way valve 50. The one-way valve 50 can be a duckbill valve. The one-way valve 50 allows the liquid sucked by the suction member 20 to flow to the bottle 10, while the liquid in the milk storage chamber 101 cannot flow back through the one-way valve 50. The elastic cavity 60 can be a cavity made of elastic material, and the shape of the elastic cavity 60 can be any suitable shape, such as a sphere, a cube, a bowl, etc. For example, the elastic cavity 60 is an elastic bowl. The elastic cavity 60 can be connected to the horn cover 220 through the liquid guide tube 210. The main unit 30 evacuates the inside of the elastic cavity 60, causing the elastic cavity 60 to deform and creating a negative pressure inside the milk storage chamber 101. The negative pressure creates a suction force on the breast, causing the horn cover 220 to adhere to the breast and further extract milk.

[0080] The breast pump provided in this application improves user comfort during breast pumping by incorporating a heating element 230 on the horn cover 220 to increase its temperature during use, and by using a temperature sensor 280 to regulate the temperature. This enhances the user's comfort during breast pumping, unblocks milk ducts, and increases milk output. It avoids the need for separate heating gel pads or other heating devices during breast pumping, making operation simple and convenient. Furthermore, the breast pump has an independent bottle 10 for directly collecting and storing the pumped milk, making milk storage and transfer more convenient. The suction component 20 is detachable, facilitating replacement and reprocessing of the suction assembly 200, thus improving the reusability of the device.

[0081] The above description is only a part of the embodiments of this application and does not limit the scope of protection of this application. Any equivalent device or equivalent process transformation made based on the content of this application specification and drawings, or direct or indirect application in other related technical fields, are similarly included in the patent protection scope of this application.
