Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and in particular to a reinforced breast pump. Background Technology

[0002] Breast pumps are used to express breast milk accumulated in the mammary glands. They typically use a vacuum device to alternately change the internal air pressure, simulating a "suction-extraction" action to draw milk from the breast. After passing through the three-way connector, the milk enters the breast pump and is finally stored in a bottle. Because breast pumps need frequent cleaning, especially the three-way connector which is the essential container for milk, it is necessary to design the connector to be detachable for easy removal and cleaning.

[0003] However, due to the relatively suspended structure of the three-way connector inside the breast pump, the connector is not securely fixed. Once the breast pump is disassembled and cleaned for a long time or subjected to impacts such as collisions, the three-way connector is often not tightly fixed, which affects the milk expression effect.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] The following is for reference. Figure 1 and Figure 2 This invention describes a reinforced breast pump according to an embodiment of the present invention.

[0033] like Figure 1 and Figure 2 As shown, the reinforced breast pump according to an embodiment of the present invention includes a main body shell 100, a milk suction surface component 200, and a three-way connector 300.

[0034] The main housing 100 has an inner cavity 110 for holding breast milk. The front side of the main housing 100 is provided with an installation port 120, and the rear side wall of the inner cavity 110 is provided with a first support part 130. The milk suction surface component 200 is located on the installation port 120, and the milk suction surface component 200 is provided with a milk suction hole 210. The three-way component 300 is located inside the main housing 100. There is a space between the rear side of the outer side wall of the three-way component 300 and the rear side wall of the inner cavity 110. The front side of the three-way component 300 is provided with a first through hole 310, which communicates with the milk suction hole 210. The rear side of the three-way component 300 is provided with a second support part 340, which abuts against the first support part 130.

[0035] For example, such as Figure 1 and Figure 2 As shown, the main housing 100 has an inner cavity 110 for holding breast milk. A mounting port 120 is provided on the front side of the main housing 100, communicating with the inner cavity 110. A first support portion 130 is provided on the rear side wall of the inner cavity 110, and the first support portion 130 is relatively fixed within the inner cavity 110. A milk-suction surface component 200 is located on the mounting port 120, and the milk-suction surface component 200 is provided with a milk-suction hole 210. When fixed on the mounting port 120, the milk-suction surface component 200 is relatively fixed. A three-way connector 300 is located inside the main housing 100, and a space is left between the rear side of the outer side wall of the three-way connector 300 and the rear side wall of the inner cavity 110 to ensure that the inner cavity 110 has sufficient space to hold breast milk. The front side of the three-way connector 300 has a first through hole 310, which communicates with the milk suction hole 210. That is, the milk suction hole 210 on the milk suction surface component 200 aligns with the first through hole 310 on the three-way connector 300, allowing milk drawn from the breast to pass through the milk suction hole 210 and the first through hole 310 into the three-way connector 300. The rear side of the three-way connector 300 has a second support portion 340, which is fixed to the three-way connector 300. The second support portion 340 presses against the first support portion 130, thus providing auxiliary support for the three-way connector 300.

[0036] When the breast pump of this utility model needs to be cleaned, refer to... Figure 3Then, remove the milk-suction surface component 200 from the mounting port 120 of the main unit housing 100, and then remove the three-way connector 300 as well. In this way, the main unit housing 100, the milk-suction surface component 200 and the three-way connector 300 can be cleaned separately.

[0037] After cleaning, connect the milk suction hole 210 on the milk suction surface component 200 to the first through hole 310 on the three-way component 300. Then, insert the three-way component 300 into the inner cavity 110 of the main unit housing through the mounting port 120, and install the milk suction surface component 200 on the mounting port 120. At this time, the second support part 340 on the rear side of the three-way component 300 can abut against the first support part 130 inside the main unit housing 100, which can help support the three-way component 300 and ensure that the three-way component 300 is stable enough. This can prevent the three-way component 300 from being not fixed in place or not fitting properly, which would affect the milk suction effect.

[0038] Furthermore, the design of the second support 340 abutting against the first support 130 does not affect the space left between the rear side of the outer wall of the three-way connector 300 and the rear side wall of the inner cavity 110 of the main unit housing. This ensures that the rear side of the inner cavity 110 of the main unit housing can also accommodate breast milk, guaranteeing that the capacity of the inner cavity 110 of the main unit housing is large enough. Moreover, even after pumping is completed, when the breast pump of this invention is laid flat, the breast milk can remain in the space left between the rear side of the outer wall of the three-way connector 300 and the rear side wall of the inner cavity 110 of the main unit housing, and will not flow back into the three-way connector 300.

[0039] In some embodiments of this utility model, reference is made to Figure 6 The upper side of the three-way fitting 300 is provided with an airbag mounting cavity 350. The airbag mounting cavity 350 and the three-way fitting 300 are connected through a second through hole 320. The upper side of the airbag mounting cavity 350 has an opening. An airbag 500 is provided on the airbag mounting cavity 350. The airbag 500 has an upper opening 510. The airbag mounting cavity 350 is locked to the outside of the upper opening 510. An airbag pressure ring 140 is provided on the upper side of the inner cavity 110 of the main housing. The airbag pressure ring 140 is locked to the inside of the upper opening 510 of the airbag. This ensures that there is a sufficient seal between the position of the upper opening 510 of the airbag and the upper wall of the inner cavity 110 of the main housing, and prevents the airbag 500 from leaking when it is working to form a negative pressure.

[0040] When the airbag 500 works in conjunction with the vacuum pump device, the vacuum pump device operates intermittently, causing the airbag 500 to rise and fall rhythmically. This causes the volume of the airbag 500's interior to change intermittently, generating intermittent negative pressure. This is equivalent to partially drawing out the gas inside the three-way connector 300 through the second through-hole 320, mimicking the action of an infant sucking on a breast, thus drawing out milk. The milk drawn out and flows through the three-way connector 300 into the inner cavity 110 of the main unit housing for collection.

[0041] In some specific embodiments of this utility model, an airbag opening flange 511 is provided on the upper opening 510 of the airbag, and a pressure ring limiting protrusion 141 is provided on the outer side of the airbag pressure ring 140. The pressure ring limiting protrusion 141 presses against the upper side of the airbag opening flange 511, further ensuring that the position of the upper opening 510 of the airbag is sufficiently sealed with the upper wall of the inner cavity 110 of the main unit housing.

[0042] In some embodiments of this utility model, a third through hole 330 is provided on the lower side of the three-way connector 300, and a one-way valve 600 is provided on the third through hole 330. A concave step 360 is provided between the front side of the third through hole 330 and the lower side of the first through hole 310. Milk flowing into the three-way connector 300 flows into the inner cavity 110 of the main housing through the one-way valve 600, and the concave step 360 can effectively prevent milk in the three-way connector 300 from flowing back out of the milk suction hole 210 along the position between the front side of the third through hole 330 and the lower side of the first through hole 310.

[0043] In some embodiments of this invention, the horizontal cross-sectional area of ​​the third through hole 330 is not less than 30 mm², to ensure rapid milk discharge. The shape of the third through hole 330 is not limited, and it can adopt a through hole structure such as a circle.

[0044] In a further embodiment of this utility model, the one-way valve 600 is a silicone duckbill valve. The one-way valve 600 includes duckbill bevels on both sides, and a straight hole is formed between the lower sides of the duckbill bevels, with the straight hole facing the inner cavity 110 of the main housing.

[0045] In a further embodiment of this utility model, the concave step 360 includes a vertical step surface and a horizontal step surface. The vertical height of the vertical step surface is at least 3mm, and the horizontal length of the horizontal step surface is 0-3mm, ensuring the flow-blocking effect of the concave step 360.

[0046] In some embodiments of this utility model, a first support slope 131 is provided on the upper side of the first support part 130, and a second support slope 341 is provided on the lower side of the second support part 340. The first support slope 131 and the second support slope 341 are inclined from the rear upper side to the front lower side. The first support slope 131 of the first support part 130 abuts against the second support slope 341 of the second support part 340. In this way, the first support part 130 can provide an upward thrust on the three-way connector 300, ensuring that the connection between the upper side of the three-way connector 300 and the position corresponding to the airbag 500 is sufficiently tight and fits, ensuring that the suction force is not affected.

[0047] In some embodiments of this utility model, the second support portion 340 includes a first support plate 342 and a second support plate 343. The front ends of the first support plate 342 and the second support plate 343 are both connected to the rear side wall of the tee member 300. The rear ends of the first support plate 342 and the second support plate 343 are connected to each other. The first support plate 342 and the second support plate 343 form a right angle, that is, the first support plate 342 and the second support plate 343 form a "<" shape. This gives the second support portion 340 a certain elasticity, so that the first support portion 130 fits the second support portion 340 more closely and stably.

[0048] In some embodiments of this utility model, support side limiting plates 132 are respectively provided on the left and right sides of the first support part 130. The support side limiting plates 132 lock the left and right sides of the second support part 340 to prevent the second support part 340 from shifting or misaligning laterally when the first support part 130 presses against the second support part 340.

[0049] In some embodiments of this utility model, reference is made to Figure 4 , Figure 5 The main housing 100 has a milk pouring port 170 on its upper side, and the milk suction surface component 200 has a positioning ring 220 on its upper side, which is fitted onto the milk pouring port 170. The milk pouring port 170 facilitates the pouring of milk from the inner cavity 110 of the main housing. Furthermore, the positioning ring 220 on the milk suction surface component 200, fitted onto the milk pouring port 170, further ensures a more secure installation of the milk suction surface component 200.

[0050] In a further embodiment of this utility model, the milk inlet 170 is connected to the inner cavity 110 of the main unit housing through the through groove 162 of the front support plate.

[0051] In some embodiments of this utility model, reference is made to Figure 4 , Figure 7 The mounting port 120 has a mounting port flange 121 on its outer edge, and the milk suction surface component 200 has an outer milk suction surface retaining edge 230 and an inner milk suction surface retaining edge 240 on its rear outer edge, as shown in the reference. Figure 2 The outer edge 230 of the milk-suction surface is locked onto the outer side of the mounting port flange 121, and the inner edge 240 of the milk-suction surface is locked onto the inner side of the mounting port 120, ensuring that the edge of the milk-suction surface component 200 is sufficiently fitted and securely connected to the mounting port 120, preventing milk or gas in the inner cavity 110 of the main unit housing from leaking out from the gap between the mounting port 120 and the milk-suction surface component 200.

[0052] In some specific embodiments of this utility model, a milk suction hole flange 211 is provided on the milk suction hole 210. The milk suction hole flange 211 can lock the rear position of the first through hole 310, making the connection between the milk suction surface component 200 and the three-way component 300 more stable.

[0053] In some specific embodiments of this utility model, the milk suction surface component 200 includes a horn cover 250, and the milk suction hole 210 is located in the middle of the horn cover 250, which can better fit the breast.

[0054] In a further embodiment of this utility model, the speaker cover 250 is provided with a petal massage protrusion 251, which can play a massage role for the breast.

[0055] In a further embodiment of the present invention, at least the horn cover 250 of the breast-feeding surface component 200 is made of silicone material, and the horn cover 250 makes the breast more comfortable when it fits the breast.

[0056] In some specific embodiments of this utility model, the horizontal length of the first through hole 310 of the three-way component 300 is no greater than 12mm.

[0057] In some specific embodiments of this utility model, the first through hole 310 of the three-way component 300 is provided with a first through hole flare 311, so that when the first through hole 310 is connected with the milk suction hole 210, it fits more closely to the rear side of the flare cover 250, and provides support for the flare cover 250 near the milk suction hole 210.

[0058] In a further embodiment of this utility model, the horizontal length of the first through hole flared mouth 311 is no more than 13mm, ensuring that the position of the first through hole 310 of the three-way component does not "protrude" from the main housing 100.

[0059] In some embodiments of this utility model, reference is made to Figure 3 , Figure 8 A top cover 400 is mounted on the upper side of the main housing 100. A vacuum pump 410 is built into the top cover 400.

The vacuum pump 410 communicates with the inner cavity of the airbag 500 through the external vacuum pump connection hole 420 and the external negative pressure port 150.

[0060] During actual breast pumping, the upper cover 400 is placed on the main housing 100. The external negative pressure port 150 on the main housing 100 is inserted into the vacuum pump external port 420 on the lower side of the upper cover 400, and the upper cover alignment groove 430 on the upper cover 400 engages with the main housing alignment rib 161 on the main housing 100, ensuring that the upper cover 400 is securely and reliably installed. After the breast pumping is completed, the upper cover 400 can be removed.

[0061] In a further embodiment of this utility model, a milk pouring port 170 is provided on the upper side of the main housing 100, and a milk pouring port fixing ring 171 is provided on the outer wall of the milk pouring port 170.

[0076] According to the reinforced breast pump of this utility model embodiment, the following effects can be achieved through the following configuration: When the breast pump needs to be cleaned, the main body shell 100, the milk suction surface component 200, and the three-way connector 300 can be disassembled for cleaning; after cleaning, the main body shell 100 is then reassembled with the milk suction surface component 200 and the three-way connector 300. The second support portion 340 on the rear side of the three-way connector 300 can abut against the first support portion 130 inside the main body shell 100, thus providing auxiliary support for the three-way connector 300 and ensuring that the three-way connector 300 is sufficiently stable. This design avoids situations where the T-joint 300 is not securely fixed or fits properly, which could affect the milk expression effect. The space between the rear side of the outer wall of the T-joint 300 and the rear side wall of the inner cavity 110 of the main unit housing allows the rear side of the inner cavity 110 of the main unit housing to also accommodate milk, ensuring that the capacity of the inner cavity 110 of the main unit housing is large enough. After milk expression, when the breast pump is laid flat, the milk can remain in the space between the rear side of the outer wall of the T-joint 300 and the rear side wall of the inner cavity 110 of the main unit housing, and will not flow back into the T-joint 300.
