Description

Technical Field

[0001] The utility model relates to the technical field of breast pumps, in particular to a breast pump that is convenient to block. Background Art

[0002] A breast pump is a commonly used tool for lactating 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 cover body, a three-way joint, and a milk bottle; the three-way joint includes a milk inlet, a negative pressure port, and a milk outlet. A cover body is arranged at the milk inlet, the negative pressure port is connected to the breast pump main unit, a one-way valve is arranged at the milk outlet and a milk bottle is arranged. When the breast pump main unit works, the air pressure in the three-way joint changes, causing the mother's breast in contact with the cover to be subjected to suction, so that milk is secreted from the nipple of the breast into the three-way joint. The milk accumulates at the milk outlet and passes through the one-way valve into the milk bottle, and so on until the milk sucking is completed.

[0003] In the prior art, as disclosed in a breast milk pad and a breast pump with the Chinese patent application number 202122324169.0, it discloses the structure and working principle of a breast pump. It uses the upper connector of the three-way joint to connect a negative pressure device, and air holes are arranged on the negative pressure device for connecting an external suction pump. When the suction pump works to generate suction, the negative pressure device generates negative pressure. The negative pressure generated by the negative pressure device causes the air pressure in the three-way joint to change, so that suction is generated at the bell mouth. After the milk enters from the bell mouth, it will flow to the lower connector and flow into the milk bottle connected to the lower connector.

[0004] However, when a mother uses a breast pump, some mothers, out of privacy considerations, will cover the breast pump and the breast with clothes after the breast pump is fixed in cooperation with the breast. In the above-mentioned comparative document, the upper connector of the protruding three-way joint and the negative pressure device fixed on the upper connector cause the negative pressure device and other structures to extend far in the direction away from the breast when the mother uses the breast pump. The structure of the negative pressure device faces the clothes. Therefore, when the clothes block the breast pump, the clothes will contact the structure part of the negative pressure device, and the negative pressure device will cause the clothes to protrude excessively, resulting in a large gap between the clothes and the breast, so that the clothes cannot effectively block the breast and protect privacy; and the pipeline connecting the negative pressure device to the external air source usually extends in the direction away from the opening direction of the bell mouth. When the clothes cover part of the breast pump, the clothes will squeeze the pipeline, causing the clothes to apply pressure to the pipeline, resulting in the pipeline being bent. The bending of the pipeline may cause the external air source to not be normally connected to the inside of the three-way joint, affecting the milk sucking effect. Summary of the Utility Model

Specific embodiments

[0017] The following combines the drawings in the embodiments of the present utility model to describe the technical solutions in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Therefore, the detailed description of the embodiments of the present utility model provided in the following drawings is not intended to limit the scope of the present utility model to be protected, but only represents the selected embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present utility model.

[0018] Embodiment 1: In the prior art, the three-way structure of the breast pump makes the breast shield, the negative pressure device and the milk bottle of the breast pump in three different directions. When the breast pump is in use, the negative pressure device is on the opposite side of the breast shield. Therefore, the negative pressure device is far from the breast. When the mother wants to cover the breast and the breast pump during milk pumping, the structure of the negative pressure device of the breast pump makes the width of the breast pump (the distance between the farthest ends of the breast pump in the horizontal direction from the breast) large. Between the clothes and the breast, the horizontal space occupied by the breast pump is large, resulting in the clothes being far from the breast, and others can easily see the mother's breast from the neckline of the mother, resulting in the exposure of the mother's privacy. To solve this problem, the breast pump that is convenient for shielding provided in Embodiment 1 of the present utility model is as Figures 1 to 4As shown in the figure, it includes a horn cover 1, a milk bottle 2, a two-way component 3 and a negative pressure connection component 4; the two-way component 3 includes a first communication hole 31 and a second communication hole 32; the small opening of the horn cover 1 is fixedly communicated with the first communication hole 31; the negative pressure connection component 4 has an accommodation cavity; an inlet milk port 41, an outlet milk port 42 and a communication port 43 are formed on the negative pressure connection component 4; the inlet milk port 41 is fixedly communicated with the second communication hole 32; the outlet milk port 42 is detachably fixed to the milk bottle 2; a bottom plate 44 and an airbag 45 are arranged in the accommodation cavity of the negative pressure connection component 4; the bottom plate 44 seals the outlet milk port 42; a fixing hole is formed on the bottom plate 44; a duckbill valve 46 is just fixed in the fixing hole (the duckbill valve 46 completely blocks the fixing hole, and the liquid on one side of the fixing hole can only pass through the duckbill valve 46 to the other side of the fixing hole); the inlet of the duckbill valve 46 faces the second communication hole 32; the outlet of the duckbill valve 46 faces the milk bottle 2; the airbag 45 can change in volume with the change of the internal air pressure; the airbag 45 is fixed on the upper side of the bottom plate 44; the airbag 45 is arranged on one side of the inlet of the duckbill valve 46; the airbag 45 includes a sealed cavity; a ventilation hole 451 is formed on the airbag 45; the ventilation hole 451 is communicated with the communication port 43 through a ventilation pipe.

[0019] When the breast pump provided in Embodiment 1 of the present utility model is in use, the mother's nipple is closely attached to the breast shield 1. The external air source (usually the breast pump main unit that can provide suction) is connected to the communication port 43 through a pipeline, so that the volume of the airbag 45 periodically increases and decreases (the air source sucks out the gas in the airbag 45, the volume of the airbag 45 decreases, the air source stops sucking the gas in the airbag 45, and the airbag 45 restores its volume and becomes larger), thereby causing the air pressure in the space above the bottom plate 44 of the negative pressure connection assembly 4 to change (when the volume of the airbag 45 decreases, the air pressure in the closed space surrounded by the mother's breast, the inner wall of the breast shield 1, the inner wall of the two-way assembly 3, and the upper surface of the bottom plate 44 becomes smaller), thereby generating negative pressure on the mother's breast. The milk secreted from the nipple of the mother's breast enters the two-way assembly 3 through the first communication hole 31 and reaches the negative pressure connection assembly 4 from the second communication hole 32. After the milk falls on the bottom plate 44, it will flow along the upper surface of the bottom plate 44 to the fixing hole and enter the inlet of the duckbill valve 46. When the milk accumulates to a certain amount, the duckbill valve 46 opens due to the gravity of the milk, and the milk thus passes through the duckbill valve 46 through the bottom plate 44 and flows into the milk bottle 2 from the milk outlet 42; compared with the prior art in which a tee is provided, resulting in a long distance between the negative pressure connection assembly structure and the mother's breast, in this embodiment, since there is only a two-way structure, the part of the negative pressure connection assembly 4 that generates negative pressure is arranged between the second communication hole 32 and the milk bottle 2. Therefore, when the breast pump is in use (when the breast shield 1 is close to the mother's breast), the structural width of the breast pump in the horizontal direction is smaller than that of the common breast pumps in the prior art, so that when the mother covers the breast pump and the breast with clothes, the breast milk is not easily exposed and privacy is not violated; in addition, since the negative pressure connection assembly 4 is arranged between the two-way assembly 3 and the milk bottle 2, when the communication port 43 opened on the negative pressure connection assembly 4 is connected to the external air source through a pipeline, the pipeline is not easily in direct contact with the clothes. Because the existing negative pressure connection assembly is a structure that protrudes outwards with an opening facing away from the breast shield, and the position of the communication port connected to the air source is on this protruding structure, the pipeline connected to the external air source is easily affected by contact with the clothes. However, in the device provided in this embodiment, the position of the communication port 43 is arranged between the two-way assembly 3 and the milk bottle 2 (the opening direction of the communication port 43 can be perpendicular to the opening direction of the breast shield, so that the arrangement direction of the pipeline is between the clothes and the breast; the opening direction of the communication port 43 can also be the same as the opening direction of the breast shield, so that the pipeline extends towards the breast direction and bends downwards. Since there is a gap between the mother's body and the clothes below the breast, the pipeline can pass through between the milk bottle 2 and the mother's body and under the breast), so that the pipeline connected to the communication port 43 is not directly in contact with the clothes, preventing the situation where the pipeline is blocked due to the clothes squeezing the pipeline.

[0020] The breast pump provided in Embodiment 1 of the present utility model solves the problem that it is inconvenient for a mother to protect privacy when using a breast pump in the prior art. It can facilitate the mother to cover the breast pump and the chest when using the new breast pump, thereby better protecting privacy.

[0021] As a preferred solution, in this embodiment, the airbag 45 includes a flexible film 452 in the shape of a flexible cover; the negative pressure connection assembly 4 further includes a tubular side plate 47; the bottom plate 44 is fixed at the lower pipe orifice of the side plate 47; the bottom plate 47 is a rigid bottom plate 47; the flexible film 452 is fixedly connected to the inner side surface of the side plate 47; the upper surface of the bottom plate 44, the inner side surface of the cover shape of the flexible film 452 and the inner wall of the pipe of part of the side plate 47 form a sealed cavity; a ventilation hole 451 is provided on the side plate 47. The volume change of the airbag 45 in this embodiment is realized through the flexible film 452. The flexible film is a commonly used structure in the breast pump. When an external air source generates suction, the suction is provided to the ventilation hole 451 through the pipeline from the communication port 43, so that the air pressure in the sealed cavity formed by the upper surface of the bottom plate 44, the inner side surface of the cover shape of the flexible film 452 and the inner wall of the pipe of part of the side plate 47 becomes smaller. To stabilize the air pressure balance between the sealed cavity and the outside, the flexible film 452 deforms, so that the volume of the sealed cavity becomes smaller, thereby realizing the volume reduction of the airbag 45. After stopping providing suction, the flexible film 452 restores its elastic deformation by itself, and the volume of the airbag 45 is restored.

[0022] To specifically realize the connection of the negative pressure connection assembly 4 with the two-way assembly 3 and the milk bottle 2, as a preferred solution, in this embodiment, the inner side surface of the side plate 47 is provided with a first internal thread 471 and a second internal thread 472; the first internal thread 471 is provided above the bottom plate 44; the second internal thread 472 is provided below the bottom plate 44; a first external thread 33 is provided at the outer wall of the second communication hole 32 of the two-way assembly 3; the first external thread 33 can be cooperatively connected with the first internal thread 471; a second external thread 21 is provided at the bottle mouth of the milk bottle 2; the second external thread 21 can be cooperatively connected with the second internal thread 472. After milk suction is completed, by grasping the negative pressure connection assembly 4 and the milk bottle 2, the second internal thread 472 is separated from the second external thread 21, so that the bottle mouth of the milk bottle 2 is directly communicated with the outside, thereby taking the milk from the milk bottle 2; since the structure inside the negative pressure connection assembly 4 will pass through the milk, it needs to be cleaned after each use of the breast pump. By separating the cooperation of the first internal thread 471 and the first external thread 33, the two-way assembly 3 is separated from the negative pressure connection assembly 4, so that the structure of the negative pressure connection assembly 4 is exposed outside, thereby facilitating cleaning; the negative pressure connection assembly 4, the two-way assembly 3 and the milk bottle 2 are connected by threads, which is convenient for separating the negative pressure connection assembly 4, the two-way assembly 3 and the milk bottle 2, thereby facilitating the cleaning and maintenance of the three.

[0023] Since the internal cavity of the airbag 45 is in communication with an external air source, in order to prevent dust accumulation between the flexible membrane 452 of the airbag 45 and the bottom plate 33, as a preferred solution, in this embodiment, the bottom plate 44 includes an upper housing 441 and a lower housing 442; the side of the lower housing 442 is hermetically connected to the inner wall of the side plate 47; the lower housing 442 is disposed below the ventilation hole 451; the lower housing 442 is provided with a receiving groove 4421 having an upper opening; the ventilation hole 451 is in communication with the inner cavity of the receiving groove 4421; the flexible membrane 452 is fixed on the upper housing 441; the upper housing 441 and the lower housing 442 are detachably fixed; after the upper housing 441 is fixed on the lower housing 442, the flexible membrane 452 hermetically covers the opening of the receiving groove 4421; the duckbill valve 46 is fixed on the upper housing 441; the lower housing 442 is provided with a fixing hole; when the upper housing 441 is fixed on the lower housing 442, the outlet of the duckbill valve 46 can just pass through the fixing hole. In this embodiment, the bottom plate 44 is divided into the upper housing 441 and the lower housing 442. The flexible membrane 452 is fixed on the upper housing. The lower housing provides the receiving groove 4421 for the deformation of the flexible membrane 452. The flexible membrane 452 deforms towards the inside of the receiving groove 4421, so that the volume of the cavity surrounded by the receiving groove 4421 and the flexible membrane 451 changes, thereby realizing the volume change of the airbag 45; the duckbill valve 46 is fixed on the upper housing 441, and the fixing hole is provided on the lower housing 442, so that the upper housing 441 can be positioned with respect to the lower housing 442 by the characteristic that the duckbill valve 46 can just be inserted and fixed in the fixing hole, which facilitates the connection between the upper housing 441 and the lower housing 442. The specific structure of the duckbill valve 46 is prior art and will not be elaborated here.
