[0027] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0028] With technological advancements, breast pumps on the market have gradually added heating functions. When mothers use heated breast pumps, the breast pump's horn can fit snugly around the breasts and apply heat, making the use of the pump more comfortable and minimizing the risk of breast engorgement and other health problems.

[0029] In the related art, when a wearable breast pump draws breast milk into its internal storage, the breast milk comes into contact with the bell housing. This bell housing, when used, can easily heat the breast milk in the pump significantly. The breast milk in the pump is often reheated before being fed to the baby, resulting in a second heating of the breast milk. This second heating of the breast milk can lead to a loss of nutrients and even cause bacteria growth and the production of harmful substances. To address the aforementioned issues, the present application proposes the following embodiments.

[0030] The following is an exemplary description of a breast pump according to an embodiment of the breast pump.

[0031] The breast pump 1 is a tool for expressing breast milk accumulated in the mammary glands. The breast pump 1 can fit the breast of the human body and can squeeze the mammary glands or perform negative pressure suction on the breasts to stimulate the expression of breast milk in the mammary glands and collect the breast milk.

[0032] As shown in Figures 1 to 3, a breast pump 1 includes a milk reservoir 10 and a bell housing 20. The bell housing 20 can be snapped onto the nipple and areola of a human breast to collect breast milk. The milk reservoir 10 is hermetically connected to the bell housing 20, collecting and storing breast milk that flows out of the bell housing 20.

[0033] Optionally, as shown in Figures 1 to 3, the speaker cover 20 may include a cover body 210 and an arc-shaped heating element 220. The cover body 210 may be sealedly connected to the milk chamber 10, and the arc-shaped heating element 220 may be disposed inside the cover body 210. Specifically, the cover body 210 may contact and fit the human body, and the arc-shaped heating element 220 may heat the human breast through the cover body 210, so that the breast pump 1 can achieve a hot compress function. In addition, the arc-shaped heating element 220 may transmit a gentler and more uniform heat to the human skin through the cover body 210. Furthermore, disposing the arc-shaped heating element 220 inside the cover body 210 may enable the cover body 210 to protect the arc-shaped heating element 220, reduce exposure of the arc-shaped heating element 220, thereby improving the waterproof and dustproof effects, and thus improving the electrical safety of the breast pump 1.

[0034] The arc-shaped heating element 220 can be, for example, C-shaped or U-shaped. Since a mother's breast is typically hemispherical or quasi-hemispherical, the arc-shaped heating element 220 can adapt to the shape of the breast and provide a larger heating area for the breast, thereby enabling the arc-shaped heating element 220 to better heat the breast and enhance the heating effect of the arc-shaped heating element 220.

[0035] In some embodiments, as shown in Figures 2 and 3, the breast pump 1 may further include a main unit 30. The milk chamber 10 may be provided with a storage area 110, and the main unit 30 may be accommodated in the storage area 110. The main unit 30 may be connected to the milk chamber 10 and the speaker housing 20. The main unit 30 may be connected to the arc-shaped heating element 220 and may control the arc-shaped heating element 220 to perform heating. Optionally, the main unit 30 may include control components such as a circuit board and a processor, and may control the arc-shaped heating element 220 via these control components.

[0036] Alternatively, as shown in the figures, such as those shown in Figures 2 to 5, the housing 210 may include a first terminal assembly 211, which is disposed on the arc-shaped heating element 220, and the host 30 may be provided with a second terminal assembly 310, the first terminal assembly 211 and the second terminal assembly 310 being electrically connected. The host 30 is electrically connected to the arc-shaped heating element 220 via the first terminal assembly 211 and the second terminal assembly 310, so that the host 30 can control the arc-shaped heating element 220.

[0037] Specifically, after the speaker cover 20 is connected and assembled with the milk chamber component 10 and the main unit 30, a sealed space can be formed at the connection between the first terminal component 211 and the second terminal component 310, so that it is not easy for moisture, breast milk and other liquids or impurities such as dust to enter the connection between the first terminal component 211 and the second terminal component 310 and affect the connection between the two, and it is also not easy for them to enter the interior of the main unit 30 and the cover body 210 from the connection between the first terminal component 211 and the second terminal component 310, so as to protect the main unit 30 and the arc-shaped heating element 220 and improve the electrical safety of the breast pump 1.

[0038] Optionally, as shown in Figures 3 and 4 , the housing 210 may include a lower region 213 and an upper region 212 connected to each other along the height of the breast pump 1. The lower region 213 and the milk silo 10 may enclose a milk storage chamber 40. The milk storage chamber 40 can be used to store breast milk. The arrangement of the housing 210 and the milk silo 10 enclosing the milk storage chamber 40 can reduce the size of the breast pump 1, allowing it to occupy less space and simplifying its structure.

[0039] In some embodiments, as shown in Figures 3 and 4, the milk storage chamber 10 may include a top wall 120 for enclosing the milk storage chamber 40. The upper region 212 and the lower region 213 may be divided by a plane X on which the top wall 120 lies. By configuring the top wall 120 of the milk storage chamber 40 as the interface between the upper region 212 and the lower region 213, the breast milk in the milk storage chamber 40 can all contact the corresponding lower region 213, thereby better distinguishing the location of the breast milk in the breast pump 1.

[0040] At least part of the arc-shaped heating element 220 may be located in the upper region 212. In the height direction of the breast pump 1, the ratio of the height of the arc-shaped heating element 220 in the upper region 212 to the total height thereof may be greater than or equal to 0.7.

[0041] 3 and 4 , the height of the arc-shaped heating element 220 in the upper region 212 may be as shown by the arrow B in FIG. 3 and FIG. 4 , the total height of the arc-shaped heating element 220 may be as shown by the height D in FIG. 3 and FIG. 4 , and C:D ≥ 0.7.

[0042] Optionally, the ratio of the height of the arc-shaped heating element 220 in the upper region 212 to the total height can be greater than or equal to 0.8, or 0.9. For example, the ratio of the height of the arc-shaped heating element 220 in the upper region 212 to the total height can be 0.85, 0.95, or the like. This allows the majority of the arc-shaped heating element 220 to be located in the upper region 212, with only a small portion extending into the lower region 213 of the horn housing 20. This reduces the contact area between the arc-shaped heating element 220 and the lower region 213 of the horn housing 20, thereby reducing the amount of heating of breast milk in the milk storage chamber 40 by the arc-shaped heating element 220.

[0043] Alternatively, in other embodiments, the ratio of the height of the arc-shaped heating element 220 in the upper area 212 to the total height can be equal to 1, that is, the arc-shaped heating element 220 is located entirely in the upper area 212, so that the arc-shaped heating element 220 only heats the upper area, and thus it is not easy to heat the milk in the milk storage cavity 40 corresponding to the lower area 213.

[0044] By arranging most or all of the arc-shaped heating element 220 in the upper area 212 of the cover body 210, the arc-shaped heating element 220 can achieve local heating, and the arc-shaped heating element 220 can reduce the heating of the lower area 213 during heating, wherein the lower area 213 and the milk bin 10 form a milk storage chamber 40. Therefore, when the breast pump 1 is in use, the breast milk in the milk storage chamber 40 is usually not higher than the lowest point of the arc-shaped heating element 220, thereby reducing the arc-shaped heating element 220 from heating the breast milk in the milk storage chamber 40, and further reducing the occurrence of the breast pump 1 performing secondary heating of the breast milk, thereby reducing the loss of nutrients, bacterial growth, and the production of harmful substances in the breast milk in the breast pump 1.

[0045] Optionally, as shown in Figure 3, the accommodating area 110 can be provided with an upper area 212 corresponding to the cover body 210, and the host 30 and the first terminal assembly 211 can both be connected to the upper area 212 and the arc-shaped heating element 220 to facilitate the connection between the host 30 and the arc-shaped heating element 220.

[0046] In some embodiments, as shown in Figures 2 to 4, the arc-shaped heating element 220 may include an arc segment 221 and an end segment 222. The end segment 222 is connected to at least one end of the arc segment 221 and extends from the arc segment 221. The arc segment 221 is located in the upper region 212, and the end segment 222 is located in the lower region 213. The ratio of the height of the arc segment 221 in the height direction of the breast pump 1 to the total height is greater than or equal to 0.7.

[0047] The height of the arc segment 221 in the height direction of the breast pump 1 may be shown as height C in FIG. 4 .

[0048] Optionally, the ratio of the height of the arc segment 221 in the height direction of the breast pump 1 to the total height of the arc-shaped heating element 220 can be greater than or equal to 0.8, or 0.9. For example, the ratio of the height of the arc segment 221 in the height direction of the breast pump 1 to the total height can be 0.85, 0.95, or the like.

[0049] Of course, in some embodiments, the ratio of the height of the arc segment 221 in the height direction of the breast pump 1 to the total height of the arc-shaped heating element 220 can also be 1, that is, the arc-shaped heating elements 220 are all arc segments 221, and the arc-shaped heating elements 220 are all arranged in the upper area 212 of the cover body 210.

[0050] In this way, by arranging the arc segment 221 in the upper area 212 and arranging the arc segment 221 to occupy a larger proportion in the arc-shaped heating element 220, most of the arc-shaped heating element 220 can be located in the upper area 212 or can be located entirely in the upper area 212, so that the heating of the arc-shaped heating element 220 is mainly concentrated in the upper area 212, thereby reducing the heating of the lower area 213 by the arc-shaped heating element 220 during use of the breast pump 1, thereby reducing the heating of the breast milk in the milk storage chamber 40.

[0051] In some embodiments, there can be two end segments 222, with the two end segments 222 correspondingly connected to the ends of the arc segment 221. Providing two end segments 222 correspondingly disposed at the ends of the arc segment 221 can make the heating area of ​​the arc heating segment more uniform, and can also enable the arc-shaped heating element 220 to provide a wider heating area, thereby improving the heating efficiency and heating effect of the breast.

[0052] The ratio of the height of each end segment 222 in the height direction of the breast pump 1 to the total height may be less than or equal to 0.3. Alternatively, the ratio of the height of each end segment 222 in the height direction of the breast pump 1 to the total height may be less than or equal to 0.2. Alternatively, the ratio of the height of each end segment 222 in the height direction of the breast pump 1 to the total height may be less than or equal to 0.1.

[0053] Optionally, the extended height of each end segment 222 in the height direction of the breast pump 1 may be set to correspond to the height of the arc segment 221. For example, in the height direction of the breast pump 1, the ratio of the height of the arc segment 221 to the extended height of each end segment 222 may be 7:3, 8:2, or 9:1, etc.

[0054] In some embodiments, as shown in FIG4 , a portion of the arc-shaped heating element 220 may be located in the lower region 213. The portion of the arc-shaped heating element 220 located in the lower region 213 may have a first lowest position in the height direction of the breast pump 1. Optionally, the first lowest position may be located at the end section 222. The first lowest position may be shown as position E in FIG4 .

[0055] The milk bin 10 may include a bottom wall 130 disposed opposite the top wall 120. The bottom wall 130 has a second lowest position in the height direction of the breast pump 1. The bottom wall 130 may be located at the bottom of the milk bin 10. The second lowest position may be shown as position F in FIG4 .

[0056] The distance between the first lowest position and the plane where the top wall 120 is located in the height direction can be set to a first distance, the distance between the second lowest position and the plane where the top wall 120 is located in the height direction can be set to a second distance, and the ratio of the first distance to the second distance is less than 0.4.

[0057] The first distance may be shown as the distance G in FIG. 4 , and the second distance may be shown as the distance H in FIG. 4 , wherein G:H≤0.4.

[0058] This arrangement allows the arc-shaped heating element 220 to extend to a higher height in the lower area 213, so that the lowest heating area of ​​the arc-shaped heating element 220 is not easily in contact with the liquid surface of the milk in the milk storage chamber 40, and the breast milk in the milk storage chamber 40 is not easily higher than the lowest point of the arc-shaped heating element 220, thereby reducing the heating of the liquid surface and the milk by the arc-shaped heating element 220, thereby reducing the occurrence of secondary heating of the breast milk by the breast pump 1.

[0059] In some embodiments, as shown in Figures 2 to 5 , the housing 210 may define a liquid inlet channel 214 extending along a predetermined axis. The housing 210 may extend from the liquid inlet channel 214 toward one side thereof in a trumpet-like configuration. The liquid inlet channel 214 may communicate with the milk storage chamber 40, and the arc-shaped heating element 220 may be disposed about the predetermined axis. The predetermined axis may be indicated by I in Figure 5 .

[0060] The shield 210 is configured to extend from the liquid inlet channel 214 to one side thereof in a trumpet shape, so that the shape of the shield 210 can correspond to the human breast, allowing the shield 210 to be buckled onto the nipple and areola to fit the human breast better, creating a negative pressure suction on the breast, and facilitating the shield 210 to stimulate the nipple to secrete milk and collect breast milk. The milk can then enter the milk storage chamber 40 through the liquid inlet channel 214.

[0061] The arc-shaped heating element 220 is arranged around a preset axis, so that the shape of the heating element can fit the shape of the cover body 210 and the shape of the breast, thereby expanding the heating area and better realizing the hot compress function.

[0062] In some embodiments, as shown in FIG. 2 to FIG. 5 , the cover body 210 may include an annular fitting portion 215 , a trumpet-shaped connecting portion 216 , and a channel portion 217 .

[0063] The annular fitting portion 215, the trumpet-shaped connecting portion 216, and the channel portion 217 are sequentially connected. The trumpet-shaped connecting portion 216, with its larger circumferential end, is connected to the annular fitting portion 215, while the trumpet-shaped connecting portion 216, with its smaller circumferential end, is connected to one end of the channel portion 217. The other end of the channel portion 217 extends away from the trumpet-shaped connecting portion 216. The liquid inlet channel 214 is formed in the channel portion 217. The annular fitting portion 215 is configured to fit against human skin, and the arc-shaped heating element 220 is disposed within the annular fitting portion 215.

[0064] The trumpet-shaped connecting portion 216 and the channel portion 217 can correspond to the human areola and nipple. When a user uses the breast pump 1 described in this application, the nipple can be placed in the channel portion 217, and the trumpet-shaped connecting portion 216 can fit the human areola. The trumpet-shaped connecting portion 216 can also fit the human body at the location of the areola or around the areola, so that the breast pump 1 can better fit the human body and is not likely to fall off, and can generate better negative pressure suction during operation.

[0065] Among them, the arc-shaped heating element 220 is set on the annular fitting part 215, so the arc-shaped heating element 220 can indirectly apply heat to the position of the human areola or the periphery of the areola through the annular fitting part 215, thereby alleviating the swelling and pain of the mother's breast when using the breast pump 1, and also increasing the mother's milk output and milk output speed.

[0066] In some embodiments, as shown in FIG4 , a channel portion 217 can be provided in the lower region 213 of the housing to communicate with the milk storage chamber 40. In the height direction of the breast pump 1, the lowest position of the liquid inlet channel 214 can be flush with the first lowest position of the arc-shaped heating element 220, or the lowest position of the liquid inlet channel 214 can be lower than the first lowest position of the arc-shaped heating element 220. The lowest position of the liquid inlet channel 214 can be shown as position J in FIG4 .

[0067] During the breast milk collection process, if the milk in the milk storage chamber 40 is higher than the lowest point of the liquid inlet channel 214, the milk will overflow from the milk storage chamber 40 through the liquid inlet channel 214. Therefore, when the breast pump 1 is placed horizontally along its height, the highest liquid level in the milk storage chamber 40 is lower than the lowest point of the liquid inlet channel 214. Therefore, setting the first lowest point of the arc-shaped heating element 220 higher than or flush with the lowest point of the liquid inlet channel 214 can reduce the heating of the milk in the milk storage chamber 40 by the arc-shaped heating element 220 and expand the heating area of ​​the arc-shaped heating element 220.

[0068] Among them, at least a portion of the outer peripheral wall of the channel portion 217 is exposed to the milk storage cavity 40, which can facilitate the breast milk in the liquid inlet channel 214 to enter the milk storage cavity 40.

[0069] In some embodiments, as shown in Figures 2 to 5, the arc-shaped heating element 220 may surround the inner ring 2152 of the annular fitting portion 215, and the arc-shaped heating element 220 may be closer to the outer ring 2151 of the annular fitting portion 215 between the inner ring 2152 and the outer ring 2151 of the annular fitting portion 215.

[0070] Furthermore, the inner ring 2152 and the outer ring 2151 of the annular fitting portion 215 are both arranged in a ring shape around a preset axis, the inner ring 2152 and the outer ring 2151 of the annular fitting portion 215 are connected to each other, the inner ring 2152 of the annular fitting portion 215 is correspondingly connected to the trumpet-shaped connecting portion 216, and the outer ring 2151 extends from the inner ring 2152 to the periphery.

[0071] Since the inner ring 2152 and the outer ring 2151 of the annular fitting portion 215 are both arranged in a ring shape around a preset axis, arranging the arc-shaped heating element 220 on the outer ring 2151 on the periphery can make the extension length of the arc-shaped heating element 220 longer and the size larger, thereby expanding the heating area of ​​the arc-shaped heating element 220 and improving the heating effect of the arc-shaped heating element 220.

[0072] In some embodiments, as shown in Figures 2 to 3, the cover body 210 can be configured to be integrally formed and the arc-shaped heating element 220 can be covered therein by the integral forming. The outer periphery of the cover body 210 can be provided with an interlocking groove 218 facing the middle area of ​​the cover body 210, and the outer periphery of the milk bin part 10 is provided with an interlocking edge 140, which is embedded in the interlocking groove 218, so that the cover body 210 and the milk bin part 10 are sealed and connected.

[0073] Optionally, the cover 210 can be formed by injection molding, wherein the cover 210 can wrap the arc-shaped heating element 220 inside the cover during the injection molding process, so that the arc-shaped heating element 220 can fit tightly with the cover 210 and the difficulty of manufacturing the speaker cover 20 can be reduced.

[0074] Since injection molding has the advantages of fast molding speed and precise product size, injection molding is adopted, which can make the size of the cover body 210 more precise, so that the cover body 210 can be better sealed and connected with the milk bin 10.

[0075] Optionally, the housing 210 can be made of soft silicone. This configuration allows the speaker housing 20 to adapt to different breast shapes and fit snugly, thereby facilitating negative pressure suction by the breast pump 1. Furthermore, soft silicone has a certain degree of elasticity, so when the outer peripheral engagement edge 140 of the milk bin 10 engages with the engagement groove 218 of the housing 210, the engagement groove 218 can fit snugly with the engagement edge 140, ensuring a secure connection between the housing 210 and the milk bin 10 while enhancing the sealing effect.

[0076] The sealed connection between the cover body 210 and the milk bin 10 can prevent liquids such as moisture or impurities such as dust from entering the cover body 210 and the milk bin 10 to contaminate breast milk or damage the main unit 30 and the arc-shaped heating element 220.

[0077] In summary, the present application provides an arc-shaped heating element 220 in the horn cover 20, and in the height direction of the breast pump 1, most of the arc-shaped heating element 220 is located in the upper area 212 of the horn cover 20, and only a small part extends to the lower area 213 of the horn cover 20, or the arc-shaped heating element 220 can be entirely located in the upper area 212, and the lower area 213 of the horn cover 20 and the milk bin 10 form a milk storage chamber 40. Therefore, during use of the breast pump 1, the breast milk in the milk storage chamber 40 is usually not higher than the lowest point of the arc-shaped heating element 220. Therefore, during use of the breast pump 1, the arc-shaped heating element 220 can reduce the heating of the breast milk in the milk storage chamber 40 by the arc-shaped heating element 220, thereby reducing the occurrence of secondary heating of the breast milk by the breast pump 1, thereby reducing the loss of nutrients, bacterial growth, and production of harmful substances in the breast milk in the breast pump 1.
