Description

Technical Field

[0001] This utility model relates to the field of maternal and infant products, and in particular to a breast pump, a breast pumping device and its horn cover. Background Technology

[0002] In Chinese utility model patent application CN119792681A, the inventor disclosed a breast pump comprising a back cover, a three-way connector, a horn cover, a duckbill valve, and a bottle, and having a negative pressure chamber. The horn cover includes a cover body and a deformable portion disposed at the tail end of the cover body. The cover body and the deformable portion are integrally molded from silicone material. The horn cover forms a breast pump nozzle between the cover body and the deformable portion. The cover body has a milk discharge channel communicating with the milk suction chamber. The rear part of the cover body passes through the front of the three-way connector. An opening is installed on the three-way component, and the deformable part extends out of the three-way component through the rear opening. The milk discharge channel of the cover portion connects to the bottom opening of the three-way component. The back cover is installed on the three-way component, and the periphery of the deformable part is sandwiched between the two. The negative pressure chamber of the breast pump is formed between the deformable part and the back cover. The gas channel of the back cover connects to the negative pressure chamber. The duckbill valve and the bottle are respectively installed at the bottom of the three-way component, and the bottle covers the duckbill valve. The duckbill valve selectively opens and closes the bottom opening of the three-way component. During the process of expelling gas from the negative pressure chamber of the breast pump through the gas channel of the back cover, the deformable part deforms towards the side closer to the back cover. At this time, the spout valve closes the bottom opening of the three-way component, and the space size of the suction chamber of the horn cover increases, creating a negative pressure environment in the breast pump to draw out milk and temporarily store it in the suction chamber of the horn cover. After the gas enters the negative pressure chamber of the breast pump through the gas channel of the back cover, the deformable part deforms away from the back cover. At this time, the duckbill valve opens the bottom opening of the three-way component, and the space size of the breast pump of the horn cover decreases. The milk temporarily stored in the suction chamber of the horn cover enters the bottle through the milk discharge channel of the cover part, the bottom opening of the three-way component, and the duckbill valve. This process is repeated to complete the milk pumping operation. In the existing breast pump, since the cover body and the deformable part of the horn cover are made of silicone material, the horn cover is flexible. During the pumping process, not only can the deformable part deform to make the size of the pumping chamber of the horn cover change, but the part of the cover body that inserts into the three-way connector also deforms. This causes the part and the inner wall of the three-way connector to frequently separate and re-fit, and milk will enter between the part and the three-way connector. This not only causes noise during the pumping process, but also wastes milk. Utility Model Content

[0054] Refer to the accompanying drawings of the specification of this utility model. Figures 1 to 14 A preferred embodiment of the present invention will be disclosed and described in the following description, wherein the breast pump includes a main unit 10 and at least one milk suction device 20 connected to the main unit 10, the milk suction device 20 being able to be fitted to the breast, and the milk suction device 20 being used to suck out and store milk when the main unit 10 is in operation.

[0055] Preferably, the breast pump further includes an air tube 30, one end of which is connected to the main unit 10 and the other end is connected to the breast pumping device 20, such that the breast pumping device 20 is connected to the main unit 10 through the air tube 30.

[0056] More preferably, see Appendix Figure 1The breast pump has two suction devices 20, and the air tube 30 is Y-shaped. The air tube 30 can connect both suction devices 20 to the main unit 10 simultaneously, allowing the user to pump milk from both breasts at the same time. Alternatively, in another specific example of the breast pump, both the suction device 20 and the air tube 30 are two. One air tube 30 connects one suction device 20 to the main unit 10, and the other air tube 30 connects the other suction device 20 to the main unit 10. This allows the user to pump milk from both breasts simultaneously.

[0057] Continue to refer to the appendix Figures 2 to 8 The breast pumping device 20 includes a three-way connector 21, a bare suction horn cover 22, a duckbill valve 23, and a baby bottle 24, and the breast pumping device 20 has a negative pressure chamber 25.

[0058] Specifically, the three-way component 21 has an assembly opening 211, a bottom channel 212, and a gas channel 213. Preferably, the gas channel 213 of the three-way component 21 is located at the top of the three-way component 21.

[0059] The bare suction horn cover 22 includes an assembly part 221, a horn part 222, and a deformable part 223, and has a milk discharge channel 224 and a milk suction chamber 225. The milk discharge channel 224 is formed in the assembly part 221. The horn part 222 and the deformable part 223 are respectively disposed at the front and rear of the assembly part 221. The milk suction chamber 225 is formed between the assembly part 221 and the deformable part 223, and the milk discharge channel 224 communicates with the milk suction chamber 225. Preferably, the mounting portion 221 of the bare suction horn cover 22 is cylindrical, and the outer diameter of the mounting portion 221 is the same as the inner diameter of the three-way component 21. After the mounting portion 221 is inserted into the interior of the three-way component 21 through the mounting opening 211, the peripheral wall of the mounting portion 221 and the inner wall of the three-way component 21 fit together. Based on the friction between the peripheral wall of the mounting portion 221 and the inner wall of the three-way component 21, the bare suction horn cover 22 is reliably installed on the three-way component 21.

[0060] Specifically, when the bare suction horn cover 22 is installed on the three-way component 21, the deformable portion 223 and the assembly portion 221 of the bare suction horn cover 22 extend into the interior of the three-way component 21 through the assembly opening 211 of the three-way component 21. The peripheral wall of the assembly portion 221 is attached to the inner wall of the three-way component 21. The milk discharge channel 224 of the bare suction horn cover 22 is connected to the bottom channel 212 of the three-way component 21. The negative pressure chamber 25 of the milk pumping device 20 is formed between the three-way component 21 and the deformable portion 223 of the bare suction horn cover 22. The gas channel 213 of the three-way component 21 is connected to the negative pressure chamber 25 of the milk pumping device 20. It is understood that since the peripheral wall of the assembly part 221 and the inner wall of the three-way component 21 are in close contact, the assembly part 221 and the three-way component 21 have good airtightness, thus preventing air leakage from the negative pressure chamber 25 of the milk pumping device 20.

[0061] The duckbill valve 23 is installed on the three-way component 21 and is used to open and close the bottom channel 212 of the three-way component 21. The baby bottle 24 is installed on the three-way component 21 and covers the duckbill valve 23. When the user pulls the bare suction horn cover 22 outward, the bare suction horn cover 22 and the three-way component 21 can be separated to facilitate cleaning of the breast pump 20.

[0062] In this specific example of the breast pump of this utility model, the assembly portion 221 further includes an assembly ring 2211 and a frame 2212. The milk discharge channel 224 of the bare suction horn cover 22 is formed in the assembly ring 2211. The frame 2212 is disposed in the assembly ring 2211 and surrounds the milk discharge channel 224 of the bare suction horn cover 22. The frame 2212 is used to maintain the shape of the portion of the assembly ring 2211 that defines the milk discharge channel 224 of the bare suction horn cover 22, preventing deformation of this portion of the assembly ring 2211, thereby preventing gaps from forming between the peripheral wall of the assembly portion 221 and the inner wall of the three-way component 21. The horn portion 222 is disposed extending outward and forward from the front of the assembly ring 2211, and the deformable portion 223 is disposed at the rear of the assembly ring 2211. For example, in the appendix... Figures 1 to 14 In this specific example of the breast pump of the present invention shown, the horn portion 222 extends integrally forward from the front of the mounting ring 2211, and the deformable portion 223 is integrally formed at the rear of the mounting ring 2211, that is, the mounting ring 2211, the horn portion 222 and the deformable portion 223 are integral.

[0063] When a user uses the breast pump to express milk, the breast closes the opening of the horn part 222, making the milk suction chamber 225 of the bare suction horn cover 22 a closed space. At this time, the bare suction horn cover 22 can self-adhere to the breast, realizing "bare suction". When the main unit 10 is working, it can discharge the air in the negative pressure chamber 25 of the breast pump device 20 through the gas channel 213 of the three-way component 21 to increase the negative pressure in the negative pressure chamber 25. At this time, the negative pressure in the milk suction chamber 225 of the bare suction horn cover 22 increases and the duckbill valve 23 closes the bottom channel 212 of the three-way component 21. Therefore, the milk is sucked out and temporarily stored in the milk suction chamber 225 of the bare suction horn cover 22. When the main unit 10 allows air to enter the negative pressure chamber 25 of the breast pump 20 through the gas channel 213 of the three-way component 21, the negative pressure in the negative pressure chamber 25 of the breast pump 20 decreases. At this time, the negative pressure in the milk suction chamber 225 of the bare suction horn cover 22 decreases and the duckbill valve 23 opens the bottom channel 212 of the three-way component 21. Therefore, milk is allowed to be discharged into the bottle 24 through the milk discharge channel 224 of the bare suction horn cover 22 and the bottom channel 212 of the three-way component 21. This process is repeated, and the breast pump can help the user express milk.

[0064] When a user uses the breast pump of this invention, the frame 2212 of the assembly part 221 can always maintain the shape of the part of the assembly ring 2211 that defines the milk discharge channel 224 of the bare suction horn cover 22, avoiding deformation of this part of the assembly ring 2211, thereby preventing gaps from forming between the peripheral wall of the assembly ring 2211 and the inner wall of the three-way component 21, thus avoiding noise and milk waste. At the same time, it can prevent air leakage from the negative pressure chamber 25 of the breast pumping device 20, which helps to ensure breast pumping efficiency.

[0065] Reference Appendix Figures 6 to 8 In this specific example of the breast pump of this utility model, the skeleton 2212 of the assembly part 221 is annular, surrounding the milk suction chamber 225 of the bare suction horn cover 22. In this way, the skeleton 2212 can prevent the assembly ring 2211 from deforming at any position in the entire circumferential direction. Preferably, the skeleton 2212 has a skeleton perforation 22121, the position of which corresponds to the position of the milk discharge channel 224 of the bare suction horn cover 22, so that the skeleton 2212 can surround the milk discharge channel 224 of the bare suction horn cover 22.

[0066] Continue to refer to the appendix Figure 3 , Figures 6 to 8In this specific example of the breast pump of the present invention, the skeleton 2212 is embedded inside the assembly ring 2211 to set the skeleton 2212 to the assembly ring 2211. In this way, on the one hand, the skeleton 2212 is not visually visible, and on the other hand, it helps to ensure the reliability of the connection between the assembly ring 2211 and the skeleton 2212, so that the skeleton 2212 is reliably set to the assembly ring 2211 and effectively prevents the skeleton 2212 from falling off.

[0067] The process of embedding the skeleton 2212 inside the assembly ring 2211 can be as follows: First, a ring-shaped skeleton 2212 is provided, the skeleton 2212 having skeleton perforations 22121, the skeleton 2212 can be made of plastic to improve the strength of the skeleton 2212; second, after placing the skeleton 2212 in a mold, a fluid silicone material is injected into the mold, the fluid silicone material will wrap the skeleton 2212; then, after the fluid silicone material has solidified and formed, it is removed to obtain an integral assembly ring 2211, the horn portion 222 and the deformable portion 223, and the skeleton 2212 is embedded inside the assembly ring 2211.

[0068] Preferably, the size of the skeleton perforation 22121 of the skeleton 2212 is larger than the size of the milk discharge channel 224 of the bare suction horn cover 22, so that the skeleton 2212 as a whole can be embedded inside the assembly ring 2211, avoiding milk from contacting the skeleton 2212.

[0069] Continue to refer to the appendix Figures 1 to 6 The horn portion 222 of the bare suction horn cover 22 has a concave arc surface 2221, which allows the inner wall of the horn portion 222 to adapt to the shape of the breast, which is conducive to the reliable self-adhesion of the horn portion 222 to the breast, thereby achieving "bare suction".

[0070] Further, see Appendix Figures 3 to 6The bare suction horn cover 22 includes an inner liner 226, which has an inner liner channel 2261. The inner liner 226 is detachably installed at the connection position between the assembly part 221 and the horn part 222, and the inner liner channel 2261 of the inner liner 226 communicates with the milk suction chamber 225 of the bare suction horn cover 22. In this way, on the one hand, the inner liner 226 can reduce the size of the opening of the milk suction chamber 225 of the bare suction horn cover 22, and prevent the milk temporarily stored in the milk suction chamber 225 of the bare suction horn cover 22 from flowing back. On the other hand, the inner liner 226 can form an abutment ring 2262 for abutting the areola. When the flared portion 222 of the bare suction flared cover 22 covers the breast and the breast closes the opening of the flared portion 222, the areola can abut against the abutment ring 2262 of the inner liner 226. During milk expression, as the negative pressure inside the milk expression chamber 225 of the bare suction flared cover 22 increases, the nipple and areola are pulled towards the milk expression chamber 225 of the bare suction flared cover 22. At this time, the abutment ring 2262 of the inner liner 226 can prevent the areola from entering the milk expression chamber 225 of the bare suction flared cover 22, so that the areola is squeezed by the abutment ring 2262 of the inner liner 226, thereby increasing the milk output and improving milk expression efficiency. Preferably, the inner liner 226 is made of silicone material to improve comfort.

[0071] Reference Appendix Figures 2 to 5 The breast pump 20 further includes a back cover 26, which is detachably mounted to the rear of the three-way connector 21. The back cover 26 may have a regular surface, for example, the surface of the back cover 26 is spherical. By mounting the back cover 26 to the rear of the three-way connector 21, not only is the aesthetics of the breast pump 20 improved, but also, when the breast pump 20 is placed inside the bra, the back cover 26 can provide sufficient support and prevent the breast pump 20 from sliding downwards inside the bra.

[0072] Reference Appendix Figures 3 to 5The rear cover 26 has a rear cover through hole 261 and an arc-shaped retaining ring 262. The top of the three-way component 21 has an insertion arm 214, and the gas channel 213 is formed in the insertion arm 214. After the end of the insertion arm 214 of the three-way component 21 is inserted into the rear cover through hole 261 of the rear cover 26, the arc-shaped retaining ring 262 of the rear cover 26 locks the tail of the three-way component 21, so as to facilitate the installation of the rear cover 26 onto the three-way component 21. It can be understood that when it is necessary to remove the rear cover 26, it is only necessary to apply force to the rear of the rear cover 26 to easily separate the rear cover 26 and the three-way component 21. In the breast pump of this utility model, the end of the air tube 30 can be inserted into the insertion arm 214 of the three-way component 21, so that this end of the air tube 30 is connected to the breast pumping device 20.

[0073] Reference Appendix Figure 9 and Figure 10 The breast pumping device 20 further includes a wearable horn cover 27. Unlike the bare horn cover 22, the wearable horn cover 27 uses an annular pad 271 instead of the horn portion 222 to isolate the breast and the three-way connector 21 during breast pumping, preventing direct contact between the breast and the three-way connector 21. Specifically, the wearable horn cover 27 includes the mounting portion 221, the annular pad 271, and the deformable portion 223, and has the milk discharge channel 224 and the breast pumping chamber 225. The milk discharge channel 224 is formed in the mounting portion 221. The annular pad 271 and the deformable portion 223 are respectively disposed at the front and rear of the mounting portion 221. The breast pumping chamber 225 is formed between the mounting portion 221 and the deformable portion 223, and the milk discharge channel 224 communicates with the breast pumping chamber 225. Preferably, the mounting portion 221 of the wearable speaker cover 27 is cylindrical, and the outer diameter of the mounting portion 221 is the same as the inner diameter of the three-way component 21. After the mounting portion 221 is inserted into the three-way component 21 through the mounting opening 211, the peripheral wall of the mounting portion 221 and the inner wall of the three-way component 21 fit together. Based on the friction between the peripheral wall of the mounting portion 221 and the inner wall of the three-way component 21, the wearable speaker cover 22 is reliably installed on the three-way component 21.

[0074] Specifically, when the wearable horn cover 27 is installed on the three-way component 21, the deformable portion 223 and the mounting portion 221 of the wearable horn cover 27 extend into the interior of the three-way component 21 through the mounting opening 211 of the three-way component 21. The peripheral wall of the mounting portion 221 is attached to the inner wall of the three-way component 21. The milk discharge channel 224 of the wearable horn cover 27 is connected to the bottom channel 212 of the three-way component 21. The negative pressure chamber 25 of the milk pumping device 20 is formed between the three-way component 21 and the deformable portion 223 of the wearable horn cover 27. The gas channel 213 of the three-way component 21 is connected to the negative pressure chamber 25 of the milk pumping device 20. It is understood that since the peripheral wall of the assembly part 221 and the inner wall of the three-way component 21 are in close contact, the assembly part 221 and the three-way component 21 have good airtightness, thus preventing air leakage from the negative pressure chamber 25 of the milk pumping device 20.

[0075] In this specific example of the breast pump of the present invention, the assembly part 221 further includes the assembly ring 2211 and the skeleton 2212. The milk discharge channel 224 of the wearable horn cover 27 is formed in the assembly ring 2211. The skeleton 2212 is disposed in the assembly ring 2211 and surrounds the milk discharge channel 224 of the wearable horn cover 27. The skeleton 2212 is used to maintain the shape of the part of the assembly ring 2211 that defines the milk discharge channel 224 of the wearable horn cover 27, and to prevent deformation of this part of the assembly ring 2211, thereby preventing gaps from forming between the peripheral wall of the assembly part 221 and the inner wall of the three-way component 21. The annular pad 271 is provided to extend outward and forward from the front of the assembly ring 2211, such that the annular pad 271 can fit against the edge of the assembly opening 211 of the tee component 21, and the deformable portion 223 is provided at the rear of the assembly ring 2211.

[0076] When a user uses the breast pump, the breast is placed inside the bra with the breast closed by the opening of the suction chamber 225 of the bra cover 27. The bra helps to fix the breast pump 20 in the breast position. At this time, the annular pad 271 isolates the breast from the three-way component 21, preventing direct contact between the breast and the three-way component 21. This not only improves the comfort of breast pumping but also prevents air leakage between the breast and the bra cover 27. When the main unit 10 is working, it can discharge the air in the negative pressure chamber 25 of the breast pump 20 through the gas channel 213 of the three-way component 21 to increase the negative pressure in the negative pressure chamber 25. At this time, the negative pressure in the suction chamber 225 of the bra cover 27 increases, and the duckbill valve 23 closes the bottom channel 212 of the three-way component 21. Therefore, the milk is sucked out and temporarily stored in the suction chamber 225 of the bra cover 27. When the main unit 10 allows air to enter the negative pressure chamber 25 of the breast pump 20 through the gas channel 213 of the three-way component 21, the negative pressure in the negative pressure chamber 25 of the breast pump 20 decreases. At this time, the negative pressure in the breast pump chamber 225 of the wearing horn cover 27 decreases and the duckbill valve 23 opens the bottom channel 212 of the three-way component 21. Therefore, milk is allowed to be discharged into the bottle 24 through the milk discharge channel 224 of the wearing horn cover 27 and the bottom channel 212 of the three-way component 21. This process is repeated, and the breast pump can help the user express milk.

[0077] When a user uses the breast pump of this invention to express milk, the frame 2212 of the assembly part 221 can always maintain the shape of the part of the assembly ring 2211 that defines the milk expression channel 224 of the wearing horn cover 27, avoiding deformation of this part of the assembly ring 2211, thereby preventing gaps from forming between the peripheral wall of the assembly ring 2211 and the inner wall of the three-way component 21, thus avoiding noise and milk waste. At the same time, it can prevent air leakage from the negative pressure chamber 25 of the breast pumping device 20, which helps to ensure milk expression efficiency.

[0078] Preferably, the skeleton 2212 of the assembly part 221 is annular and surrounds the milk suction chamber 225 of the wearing horn cover 27. In this way, the skeleton 2212 can prevent the assembly ring 2211 from deforming at any position in the entire circumferential direction.

[0079] In other words, the breast pump device 20 of the present invention has a naked suction state and a worn state, and the breast pump device 20 can switch between the naked suction state and the worn state.

[0080] Reference Appendix Figure 11 and Figure 12 When the user installs the bare suction nozzle 22, the duckbill valve 23, and the bottle 24 onto the three-way component 21, the breast pump 20 is in the bare suction state. At this time, the bare suction nozzle 22 can self-adhere to the breast without the need for an underwear. To ensure reliable self-adhesion of the bare suction nozzle 22 to the breast when the breast pump 20 is in the bare suction state, the user can omit the back cover 26 from the rear of the three-way component 21. This prevents the center of gravity of the breast pump 20 from shifting backward; that is, the center of gravity of the breast pump 20 is positioned forward, reducing the requirements for the suction of the bare suction nozzle 22 and thus ensuring reliable self-adhesion of the bare suction nozzle 22 to the breast.

[0081] Reference Appendix Figure 13 and Figure 14 When the user attaches the wearing horn cover 27, the duckbill valve 23, the baby bottle 24, and the back cover 26 to the three-way component 21, the breast pump 20 is in the wearing state. At this time, the bra can fix the breast pump 20 in place at the breast position. Since the back cover 26 can have a regular surface, for example, a spherical surface, it can provide sufficient support to support the bra and prevent the breast pump 20 from sliding downwards inside the bra. (Appendix) Figure 15 The illustration shows a modified example of the breast pump of the present invention, with reference to the appendix. Figures 1 to 14 The breast pump shown differs from the one described above in that it has an attached... Figure 15 In this specific example of the breast pump shown, the duckbill valve 23 is disposed on the mounting ring 2211 of the mounting portion 221 of the bare suction horn cover 22. For example, the duckbill valve 23 and the mounting ring 2211 can be integrally formed to house the duckbill valve 23 on the mounting ring 2211. In this embodiment, the duckbill valve 23 is used to open and close the milk discharge channel 224 of the bare suction horn cover 22. After the deformable portion 223 and the mounting portion 221 of the bare suction horn cover 22 extend into the interior of the three-way component 21 through the mounting opening 211 of the three-way component 21, the peripheral wall of the mounting ring 2211 fits against the inner wall of the three-way component 21, the duckbill valve 23 passes through the bottom channel 212 of the three-way component 21, the bottle 24 is installed on the three-way component 21, and the bottle 24 covers the duckbill valve 23.

[0082] When the user uses the breast pump to express milk, the breast closes the opening of the horn part 222, so that the milk suction chamber 225 of the bare suction horn cover 22 forms a closed space. When the main unit 10 is working, it can discharge the air in the negative pressure chamber 25 of the breast pump 20 through the gas channel 213 of the three-way component 21 to increase the negative pressure in the negative pressure chamber 25. At this time, the negative pressure in the milk suction chamber 225 of the bare suction horn cover 22 increases and the duckbill valve 23 closes the milk discharge channel 224 of the bare suction horn cover 22. Therefore, the milk is sucked out and temporarily stored in the milk suction chamber 225 of the bare suction horn cover 22. When the main unit 10 allows air to enter the negative pressure chamber 25 of the breast pump 20 through the gas channel 213 of the three-way component 21, the negative pressure in the negative pressure chamber 25 of the breast pump 20 decreases. At this time, the negative pressure in the suction chamber 225 of the bare suction horn cover 22 decreases and the duckbill valve 23 opens the milk discharge channel 224 of the bare suction horn cover 22. Therefore, milk is allowed to be discharged into the bottle 24 through the milk discharge channel 224 of the bare suction horn cover 22. This process is repeated, and the breast pump can help the user express milk.
