Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to a portable breast pump which is easy to clean. Background Art

[0002] A breast pump is a commonly used tool for breastfeeding mothers. A breast pump usually includes a breast pump shield and a breast pump main unit. The breast pump main unit is used to provide and control suction. The breast pump shield part usually includes a shield body, a tee and a milk bottle; the tee includes a milk inlet, a negative pressure port and a milk outlet. The shield body is provided at the milk inlet, the negative pressure port is connected to the breast pump main unit, a one-way valve is provided at the milk outlet and a milk bottle is provided. When the breast pump main unit is working, the air pressure in the tee changes, causing the mother's breast that is against the shield body to be sucked, so that milk is secreted from the nipple of the breast into the tee, the milk accumulates at the milk outlet, and passes through the one-way valve into the milk bottle, and this is repeated until the milk is sucked.

[0003] In the prior art, there is a breast pump pad and a breast pump disclosed in Chinese patent application No. 202122324169.0, which discloses the structure and working principle of a breast pump. A negative pressure device is connected to the upper connector of a three-way connector. An air hole is provided on the negative pressure device for connecting an external suction pump. The suction pump generates suction, which causes the negative pressure device to generate negative pressure. The negative pressure generated by the negative pressure device causes the air pressure in the three-way connector to change, thereby generating suction at the bell mouth. After the milk enters the bell mouth, it will flow to the lower connector and flow into the milk bottle connected to the lower connector.

[0004] However, when mothers use a breast pump, some mothers, for privacy reasons, will cover the breast pump and breast with clothing after the breast pump is fixed to the breast. However, in the above-mentioned comparative documents, the protruding upper connector of the tee joint and the negative pressure device fixed at the upper connector make the negative pressure device and other structures extend far away from the breast when the mother uses the breast pump, and the structure of the negative pressure device faces the clothing. Therefore, when the clothing blocks the breast pump, the clothing will contact the structural part of the negative pressure device, and the negative pressure device will cause the clothing to protrude excessively, resulting in a large gap between the clothing and the breast, so that the clothing cannot effectively block the breast and protect privacy; and the pipe connecting the negative pressure device to the external air source usually extends away from the direction of the bell-shaped opening. When the clothing partially covers the breast pump, the clothing will squeeze the pipe, causing the clothing to exert pressure on the pipe, causing the pipe to bend. The bending of the pipe may prevent the external air source from being normally connected to the inside of the tee, affecting the milk suction effect. Utility Model Content

[0020] The following describes the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. It is obvious that the embodiments described are only some of the embodiments of the present invention, rather than all of the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.

[0021] Example 1: In the prior art, the three-way structure of the breast pump causes the breast pump's horn, negative pressure device and milk bottle to be in three different directions. When the breast pump is in use, the negative pressure device is on the opposite side of the horn, so the negative pressure device is far away from the breast. When the mother wants to cover the breast and the breast pump during milking, the structure of the negative pressure device of the breast pump makes the width of the breast pump (the distance between the breast pump and the farthest end of the breast in the horizontal direction) large. The horizontal space occupied by the breast pump between the clothes and the breast is large, resulting in the clothes being far away from the breast. Others can easily see the mother's breast from the neckline downward, resulting in the exposure of the mother's privacy. To solve this problem, the portable breast pump that is easy to clean provided by Example 1 of the present invention is as follows: Figures 1 to 6As shown, it includes a horn cover component 1, a feeding bottle 2 and a negative pressure communication component 3; the negative pressure communication component 3 includes a tubular side plate 31, a bottom plate 32, an air bag 33 and a duckbill valve 34; the tube of the side plate 31 extends vertically; the pipe opening above the side plate 31 is the horn cover communication opening 311; the pipe opening below the side plate 31 is the feeding bottle connection opening 312; a communication opening 313 is opened on the side wall of the tube of the side plate 31; the feeding bottle connection opening 312 is sealed with the bottom plate 32; an air bag 33 is fixed above the bottom plate 32; the internal cavity of the air bag 33 is connected to the communication opening 311; a fixing hole 321 is opened on the bottom plate 32; the fixing hole 321 vertically penetrates the bottom plate 32; the duckbill valve 34 is sealed and fixed in the fixing hole 321; the inlet opening direction of the duckbill valve 34 Upward; the inlet of the duckbill valve 34 faces the speaker cover connecting port 311; the outlet opening direction of the duckbill valve 34 faces downward; the speaker cover assembly 1 includes a speaker cover 11 and a connecting assembly 12; the connecting assembly 12 has an internal cavity; the internal cavity has and only has the first through hole 121 and the second through hole 122 connected to the outside; the outer wall of the second through hole 122 of the connecting assembly 12 is provided with a card groove 1221; the inner wall of the speaker cover connecting port 311 is provided with a buckle 3111 matching the card groove 1221; the speaker cover connecting port 311 and the second through hole 122 are detachably connected and fixed; when the speaker cover connecting port 311 and the second through hole 122 are connected and fixed, the buckle 3111 is clamped in the card groove 1221; the bottle connecting port 312 and the bottle 2 are detachably connected and fixed.

[0022] When the portable breast pump provided by Example 1 of the present invention is easy to clean, the mother's nipple is pressed against the speaker cover 11 of the speaker cover assembly 1, and an external air source (usually a breast pump main unit that can provide suction) is connected to the connecting port 313 through a pipe, so that the volume of the air bag 33 can be periodically increased and decreased (the air source sucks the air in the air bag 33 out of the connecting port 313, and the volume of the air bag 33 decreases, and the air source stops sucking the air in the air bag 33, and the air bag 33 recovers and increases in volume), thereby causing the air pressure on the upper side of the bottom plate 32 of the negative pressure connecting assembly 3 to change (when the air source is in the connecting port 313, the volume of the air bag 33 decreases). When the volume of the bag 33 becomes smaller, the air pressure in the enclosed space surrounded by the mother's breast, the inner wall of the speaker cover 11, the inside of the connecting component 12, and the upper surface of the bottom plate 32 becomes smaller), thereby generating negative pressure on the mother's breast. The milk secreted by the nipple of the mother's breast enters the connecting component 12 from the speaker cover 11, and flows from the speaker cover connection port 311 to the upper side of the bottom plate 32 of the negative pressure connecting component 3. The milk flows along the upper surface of the bottom plate 32 to the fixing hole 321 and enters the inlet of the duckbill valve 34. When a certain amount of milk accumulates, the duckbill valve 34 opens due to the gravity of the milk, and the milk flows out through The duckbill valve 34 passes through the bottom plate 32, thereby flowing into the milk bottle 2 fixed at the milk bottle connection port 312, with the bottle mouth of the milk bottle 2 facing the outlet of the duckbill valve 34; compared with the prior art, because of the provision of a three-way connection, the negative pressure connecting component structure is far away from the mother's breast. In this embodiment, since the connecting component 12 of the horn cover component 1 has only two through holes, there is no need to open an additional third through hole to connect to the external air source. Therefore, the volume of the connecting component 12 can be reduced and the volume of the negative pressure component fixed to the external air source can be omitted. The negative pressure component of the prior art is arranged in the direction away from the horn cover 11. By omitting the negative pressure assembly disposed in the direction opposite to the horn cover 11, this embodiment can reduce the width of the breast pump (the distance between the breast pump and the farthest end of the breast in the horizontal direction). This allows the mother to cover the breast pump and breast with clothes, so that the clothes are closer to the mother's breast, creating a better shielding effect and preventing breast milk from being exposed and exposing privacy. In this embodiment, the negative pressure is generated by the negative pressure connecting assembly 3, which is disposed between the connecting assembly 12 of the horn cover assembly 1 and the feeding bottle 2, and is disposed directly above the feeding bottle 2. Therefore, the presence of the negative pressure connecting assembly 3 does not increase the width of the breast pump.In addition, since the negative pressure communication component 3 is arranged between the connecting component 12 and the feeding bottle 2, and the communication port 313 is provided on the negative pressure communication component 3, when the external air source is connected through the pipe, compared with the prior art, the pipe of this embodiment (the pipe connected to the communication port 313 and the external air source) is not easy to come into direct contact with clothes, because the existing negative pressure component is a structure protruding away from the opening of the horn cover, and since the position of the communication port connected to the air source is on this protruding structure, the pipe connected to the external air source is easily affected by contact with clothes (bending and obstructing the passage of airflow), while the device provided in this embodiment sets the position of the communication port 313 on the connecting component 12 The opening direction of the communication port 313 can be perpendicular to the opening direction of the speaker cover, so that the arrangement direction of the pipe is between the clothes and the breast; the opening direction of the communication port 313 can also be consistent with the opening direction of the speaker cover, so that the pipe extends toward the breast and bends downward. Since there is a gap between the mother's body and the clothes under the breast, the pipe can pass through between the milk bottle 2 and the mother's body and under the breast), so that the pipe connected to the communication port 313 will not directly contact the clothes, resulting in the pipe being squeezed by the clothes and causing the pipe to be blocked; the connection component 12 and the speaker cover 11 are detachable and fixed, which is convenient for the speaker cover 11 to be opened. Disassemble for replacement and cleaning; the connecting component 12 and the negative pressure connecting component 3 are fixed together by the card slot 1221 and the buckle 3111, which is convenient for combining and separating the second through hole 122 of the connecting component 12 and the horn cover connecting port 311 of the negative pressure connecting component 3. Because after the milk enters the connecting component 12, it will fall on the inner wall of the side plate 31 of the negative pressure connecting component 3, the bottom plate 32 and the internal structure of the negative pressure connecting component 3 such as the air bag 33. The purpose of separating the connecting component 12 from the negative pressure connecting component 3 is to facilitate the cleaning of the internal structure of the negative pressure connecting component 3. If the connecting component 12 and the negative pressure connecting component 3 cannot be separated, the presence of the connecting component 12 will affect the user When cleaning the portion of the negative pressure connection assembly 3 that contacts the bottom plate 32, the user must first pass through the connection assembly 12. During the cleaning process, the negative pressure connection assembly 3 is obscured by the connection assembly 12. This can cause stains generated on the negative pressure connection assembly 3 during use to remain during cleaning, affecting the cleanliness of the breast pump after cleaning. In this embodiment, the slot 1221 and the buckle 3111 structure allow the negative pressure connection assembly 3 to be separated from the connection assembly 12, allowing the negative pressure connection assembly 3 to be cleaned separately, thus avoiding stains remaining on the negative pressure connection assembly 3 due to the connection assembly 12 blocking the view.

[0023] The portable breast pump that is easy to clean provided in Example 1 of the present invention solves the problem in the prior art that it is inconvenient for mothers to protect their privacy when using a breast pump. It allows mothers to cover the breast pump and their breasts when using the new breast pump, thereby better protecting their privacy.

[0024] As a preferred solution, in this embodiment, the negative pressure connecting component 3 also includes an upper shell 35; the airbag 33 includes a cover-shaped flexible membrane 331; the upper shell 35 is provided with a negative pressure hole 351 in the vertical direction; the flexible membrane 331 is fixed on the upper shell 35; the flexible membrane 331 seals the upper opening of the negative pressure hole 351; the cover-shaped inner wall of the flexible membrane 331 faces the negative pressure hole 351; the upper shell 35 is detachably fixed on the base plate 32; the base plate 32 is provided with a receiving groove 322 with an upper opening; when the upper shell 35 is fixed on the base plate 32, the lower opening of the negative pressure hole 351 is sealed and connected with the upper opening of the receiving groove 322; the connecting port 312 is connected to the receiving groove 322 through a pipe.The airbag 33 is composed of a rigid bottom plate 32 and a flexible flexible membrane 331. A connecting port 311 is provided on the rigid side plate 31, which is connected to the receiving groove 322 on the rigid bottom plate 32 through a pipe. This can ensure the stability of the pipe connection connected to the external air source (if the bottom plate 32 is flexible, then the bottom plate 32 may be deformed, causing the receiving groove 322 of the bottom plate 32 to deform, which may cause the connection between the pipe and the receiving groove 322 to loosen and leak). On the other hand, the rigid bottom plate 32 separates the two sides of the negative pressure connecting component 3, so that when the airbag 33 is deformed, only the air pressure in the space above the bottom plate 32 is reduced. Instead of the air pressure inside the entire breast pump, the air pressure above the bottom plate 32 is increased (if the bottom plate 32 is flexible, when the bottom plate 32 is deformed, the air pressure in the space above and below the bottom plate 32 is reduced. When the same amount of gas is extracted from the airbag 33, the air pressure drop in the space above the bottom plate 32 will be lower than when only the flexible membrane 331 is deformed), thereby improving the suction effect of the horn cover on the mother's breast; the flexible membrane 331 is elastic. When the gas in the enclosed space formed by the flexible membrane 331 and the inner cavity of the receiving groove 322 on the upper surface of the bottom plate 32 is extracted, the flexible membrane 331 is deformed toward the inside of the receiving groove 322 , so that the air pressure in the space between the outer side of the flexible membrane 331 and the mother's breast is reduced. When the outside stops sucking the closed space formed by the flexible membrane 331 and the receiving groove 322, the flexible membrane 331 automatically deforms and recovers into a hood shape (external air enters from the communication port 311 and replenishes the closed space formed by the flexible membrane 331 and the receiving groove 322); the flexible membrane 331 is fixed to the upper shell 35, and the upper shell 35 is detachably fixed to the bottom plate 32. When the upper shell 35 is fixed to the bottom plate 32, the flexible membrane 331 seals the receiving groove 322 of the bottom plate 32. The purpose of this structure is to allow the flexible membrane 331 to It can be separated from the bottom plate 32. The purpose of separation is to facilitate the cleaning of the internal space of the airbag 33 (the hood-shaped inner wall of the flexible membrane 331 and the inner wall of the receiving groove 322) (because the internal space of the airbag 33 is connected to the external air source, the external air source may carry dust and impurities into the interior of the airbag 33, thereby causing damage to the airbag 33). On the other hand, the flexible membrane 331 is detachable from the bottom plate 32. When the flexible membrane 331 is deformed toward the receiving groove 322 but cannot recover normally, the flexible membrane 331 can be manually removed and pressure can be applied from the hood-shaped inner wall of the flexible membrane 331 to restore the flexible membrane 331.

[0025] To ensure that the flexible membrane 331 can be accurately positioned to seal the opening of the receiving groove 322, in this embodiment, a duckbill valve limiting hole 352 is further defined in the upper housing 35. The duckbill valve 34 is sealed and fixed in the duckbill valve limiting hole 352. The inlet of the duckbill valve 34 faces upward. When the upper housing 35 is fixed to the base plate 32, the duckbill valve 34 passes through the fixing hole 321. The duckbill valve 34 is inserted into the fixing hole 321 to be fixed, and at the same time, it can limit the horizontal position of the meat girl 331 and the receiving groove 322.

[0026] As a preferred embodiment, in this embodiment, the inner wall of the feeding bottle connection port 312 is provided with internal threads; the internal threads are located below the base plate 32; the mouth of the feeding bottle 2 is provided with external threads 21; and the feeding bottle connection port 312 and the feeding bottle 2 are removably fixed together through the cooperation of the internal and external threads. The feeding bottle connection port 312 is threadedly connected to the feeding bottle 2, making it convenient for the mother to remove the feeding bottle 2 and extract the milk in the feeding bottle 2. When it is necessary to re-extract milk, the feeding bottle 2 can be fixed to the negative pressure connection component 3 by following the internal threads of the feeding bottle connection port 312.

[0027] As a preferred solution, in this embodiment, the axis of the first through hole 121 is horizontal, while the axis of the second through hole 122 is vertical. The horizontal axis of the first through hole 121 allows the axis of the speaker 11 fixed to the first through hole 121 to be horizontal. The speaker cover 11, with its axis horizontal, can be in close contact with a mother's breast facing horizontally while sitting upright. The vertical axis of the second through hole 122, fixed to the speaker cover connection port 311, allows the axis of the cylindrical side plate 31 of the negative pressure communication component 3 to be vertical, thereby ensuring that the mouth of the feeding bottle 2 fixed to the negative pressure communication component 3 is vertically upward, preventing milk from leaking from the feeding bottle 2 due to tilting.
