[0037] The following is for reference. Figure 1 and Figure 2 This invention describes a compact, reclining breast pump according to an embodiment of the present invention.

[0038] like Figure 1 and Figure 2 As shown, the compact reclining breast pump according to an embodiment of the present invention includes a first component 100 and a second component 400.

[0039] The first component 100 has a built-in vacuum pump 110. A negative pressure chamber 120 is provided on the outer side of the front of the first component 100. A negative pressure chamber rear vent 211 is provided on the rear side of the negative pressure chamber 120, which communicates with the vacuum pump 110. A negative pressure chamber front hole 311 is provided on the front side of the negative pressure chamber 120. The second component 400 covers the front of the first component 100. The second component 400 has a main inner cavity 410 for holding milk. A three-way chamber 420 is provided on the second component 400. A first passage is provided on the front side of the three-way chamber 420. The three-way chamber 420 has a second through hole 422 at the rear and a third through hole 423 at the lower side. The second through hole 422 is connected to the front of the negative pressure chamber 120. The third through hole 423 is equipped with a one-way valve 500. Airflow can pass through the first through hole 421, the second through hole 422 and the front hole 311 of the negative pressure chamber in sequence to enter the negative pressure chamber 120. Milk can pass through the first through hole 421 and the third through hole 423 in sequence to enter the main inner cavity 410.

[0040] For example, such as Figure 1 and Figure 2 As shown, the first component 100 has a built-in vacuum pump 110, which serves as the power source for evacuation. A negative pressure chamber 120 is provided on the outer side of the front of the first component 100. A rear air vent 211 is provided on the rear side of the negative pressure chamber 120, which communicates with the vacuum pump 110, allowing the vacuum pump 110 to evacuate air from the negative pressure chamber 120. A front air vent 311 is provided on the front side of the negative pressure chamber 120.

[0041] Reference Figure 3 , Figure 4 The second component 400 covers the front of the first component 100, and the first component 100 and the second component 400 are detachably connected. The second component 400 has a main inner cavity 410 for holding breast milk. A three-way chamber 420 is provided on the second component 400. A first through-hole 421 is provided on the front side of the three-way chamber 420, a second through-hole 422 is provided on the rear side of the three-way chamber 420, and a third through-hole 423 is provided on the lower side of the three-way chamber 420, forming a three-way structure. The first through-hole 421 serves as the breast pump's suction port. The second through-hole 422 is connected to the front side of the negative pressure chamber 120. A one-way valve 500 is provided on the third through-hole 423. Airflow can sequentially pass through the first through-hole 421, the second through-hole 422, and the front hole 311 of the negative pressure chamber to enter the negative pressure chamber 120. Breast milk can sequentially pass through the first through-hole 421 and the third through-hole 423 to enter the main inner cavity 410.

[0042] In practical work, refer to Figure 1When the user is seated while pumping milk, the first through-hole 421 of this breast pump faces forward. When the user is lying down while pumping milk, refer to... Figure 5 The first through hole 421 of the breast pump of this utility model faces downward.

[0043] After the first through-hole 421 of the breast pump is aligned with the nipple, the vacuum pump 110 draws in air, causing the airbag membrane 130 to move. The negative pressure chamber 120 draws in air through the front hole 311 of the negative pressure chamber, creating a pressure change in the three-way chamber 420 and drawing in milk.

[0044] Under suction, the milk is sprayed through the first through hole 421 onto the inner wall of the three-way chamber 420 and flows downward. It then flows along the inner wall of the three-way chamber 420 to the third through hole 341, passes through the one-way valve 500, and flows into the main inner cavity 410 for storage.

[0045] In the above process, since the vacuum pump 110, negative pressure chamber 120 and three-way chamber 420 are compact enough, the vacuum pump 110 - negative pressure chamber 120 - three-way chamber 420 inner cavity - first through hole 421 form a straight line with a sufficiently short distance. Therefore, the suction generated by the vacuum pump 110 can better form a milk suction effect, ensuring a better milk suction effect, especially suitable for milk suction in a lying position.

[0046] In some embodiments of this utility model, reference is made to Figure 2 , Figure 3 A button 220 is provided on the rear side of the first component 100 for controlling the operation of components such as the vacuum pump 110.

[0047] In some embodiments of this utility model, reference is made to Figure 2 The first component 100 includes a rear shell 200 and a sealing sheet 300, as shown in the reference. Figure 3 , Figure 4 The vacuum pump 110 is located inside the rear housing 200. An airbag rear chamber 210 is provided on the front side of the rear housing 200, with an opening at the front. A negative pressure chamber rear air hole 211 is located on the airbag rear chamber 210. An airbag membrane 130 is provided on the airbag rear chamber 210. A sealing sheet 300 covers the front side of the rear housing 200, and a negative pressure chamber front hole 311 is located on the sealing sheet 300. This ensures that the airbag membrane 130 separates the negative pressure chamber rear air hole 211 and the negative pressure chamber front hole 311, forming two sealed air chambers on the front and rear sides, guaranteeing effective milk suction. The rear housing 200 and the sealing sheet 300 are detachable. This design facilitates the disassembly, assembly, and cleaning of the airbag membrane 130.

[0048] In some embodiments of this utility model, the rear shell 200 is made of rigid plastic, and the sealing sheet 300 is made of silicone material.

[0049] In some embodiments of this utility model, reference is made to Figure 4 , Figure 5 A first sealing ring 320 is provided at the outer edge of the front side of the sealing sheet 300. The main inner cavity 410 has an opening at the rear side. A second component edge 411 is provided at the opening at the rear side of the main inner cavity 410. The second component edge 411 is connected to the first sealing ring 320 to ensure that after the second component 400 covers the first component 100, the gap between the second component edge 411 of the second component 400 and the first component 100 is sufficiently sealed to prevent milk leakage.

[0050] In some embodiments of this utility model, a front airbag cavity 310 is provided on the rear side of the sealing sheet 300, which covers the front side of the rear airbag cavity 210. The airbag membrane 130 is located between the rear airbag cavity 210 and the front airbag cavity 310. The front hole 311 of the negative pressure chamber is located on the front airbag cavity 310. A cavity is left between the rear airbag cavity 210 and the front airbag cavity 310 as a negative pressure chamber 120. A second sealing ring 330 is provided on the front side of the sealing sheet 300. The second sealing ring 330 is connected to the rear end of the second through hole 422 to ensure that the connection gap between the negative pressure chamber 120 and the three-way chamber 420 is sufficiently sealed. This ensures that when the airbag membrane 130 in the negative pressure chamber 120 is working, the negative pressure chamber 120 can maximize the suction force on the three-way chamber 420, thus ensuring the milk suction effect.

[0051] In some embodiments of this utility model, a membrane edge 131 is provided at the edge of the airbag membrane 130, and a membrane annular slot 132 is provided on the membrane edge 131. The rear end of the airbag front cavity 310 is inserted into the membrane annular slot 132, which further ensures that the airbag membrane 130 forms two sealed air cavities on the front and rear sides of the air hole 211 and the front hole 311 of the negative pressure chamber, respectively, to prevent air leakage between the edge of the airbag membrane 130 and the inner wall of the negative pressure chamber 120, and to ensure the milk suction effect.

[0052] In some embodiments of this utility model, reference is made to Figure 4 An observation lamp 140 is provided on the upper side of the first component 100, which illuminates the main inner cavity 410. The first component 100 is made of a light-transmitting material. The observation lamp 140 illuminates the main inner cavity 410, allowing the user to easily observe the amount of milk inside. Alternatively, the first component 100 does not need to be made of a transparent material to allow for a direct view of the amount of milk inside the main inner cavity 410.

[0053] In some embodiments of this utility model, reference is made to Figure 2 , Figure 5The main inner cavity 410 has a milk pouring port 430 on its upper side, and the first component 100 has a milk overflow detection sensor 150 on its upper side. The milk overflow detection sensor 150 can detect whether milk in the main inner cavity 410 overflows from the milk pouring port 430. Milk in the main inner cavity 410 can be poured out from the milk pouring port 430. The milk overflow detection sensor 150 is responsible for checking to prevent excessive milk from overflowing from the milk pouring port 430, and then promptly feeding back to the circuit board or issuing an alert signal.

[0054] In some embodiments of this utility model, reference is made to Figure 4 , Figure 7 The main inner cavity 410 has a milk inlet 430 and a milk plug insertion hole 440 on its upper side. An anti-overflow milk plug 600 is installed on the milk inlet 430, and a milk plug insertion post 610 is installed on the lower side of the anti-overflow milk plug 600. The milk plug insertion post 610 is inserted into the milk plug insertion hole 440, thus connecting the anti-overflow milk plug 600 to the second component 400. The anti-overflow milk plug 600 acts as a sealing structure for the milk inlet 430, preventing milk from overflowing from the milk inlet 430 during milk expression. After milk expression is completed, the anti-overflow milk plug 600 can be opened, and the milk in the main inner cavity 410 can be poured out from the milk inlet 430.

[0055] In some embodiments of this utility model, the anti-overflow plug 600 is made of soft plastic.

[0056] In some embodiments of this utility model, an exhaust hole 620 is provided on the main inner cavity 410 to achieve the ventilation effect of the main inner cavity 410. In this way, during the milk pumping process, the main inner cavity 410 can be vented to the outside through the exhaust hole 620. With the help of the breast pump of this utility model, it can smoothly simulate the alternating action of "suction-expulsion" to complete the milk pumping action.

[0057] In some embodiments of this utility model, the vent 620 is located on the anti-overflow milk plug 600.

[0058] In some embodiments of this utility model, a gap is left between the anti-overflow plug 600 and the milk pouring port 430 as a venting hole 620.

[0059] In some embodiments of this utility model, the opening on the upper side of the second component 400 serves as an exhaust port 620.

[0060] In some embodiments of this utility model, reference is made to Figure 2 The one-way valve 500 is a silicone duckbill valve. The one-way valve 500 includes two duckbill bevels 510 on both sides, forming a "V" shape. A straight hole 520 is formed between the lower sides of the duckbill bevels 510. (Refer to...) Figure 7When negative pressure forms in the three-way chamber 420, the duckbill bevel 510 of the one-way valve 500 contracts to block the straight hole 520, preventing gas in the main cavity 410 from passing through the straight hole 520 into the three-way chamber 420 and affecting milk intake. When positive pressure returns to the three-way chamber 420, the duckbill bevel 510 of the one-way valve 500 resets, the straight hole 520 opens, and milk in the main cavity 410 can flow into the main cavity 410 through the straight hole 520.

[0061] In some embodiments of this utility model, the one-way valve 500 is made of soft silicone.

[0062] In some embodiments of this utility model, reference is made to Figure 5 The three-way chamber 420 includes a cylindrical temporary storage chamber 424. A second through-hole 422 is located at the rear end of the cylindrical temporary storage chamber 424, and a third through-hole 423 is located on the lower side of the cylindrical temporary storage chamber 424. An inwardly tapering annular surface 425 is provided on the front side of the cylindrical temporary storage chamber 424. The inwardly tapering annular surface 425 has a front outer circle, which is connected to the front end of the cylindrical temporary storage chamber 424. A first through-hole 421 is located at the center of the inwardly tapering annular surface 425, and an annular inclined surface 426 slopes from the first through-hole 421 towards the front outer circle of the inwardly tapering annular surface 425. When the user is lying down while pumping milk, the first through-hole 421 of this breast pump faces downwards, meaning the annular inclined surface 426 slopes from the upper side of the central axis of the inwardly tapering annular surface 425 towards the lower side of its outer circle. When milk is drawn into the three-way chamber 420 through the first through hole 421, the milk will spray onto the inner wall of the three-way chamber 420 and flow down the cylindrical temporary storage chamber 424 onto the inner annular surface 425. Then, the milk will be guided into the third through hole 423 and enter the main inner cavity 410 for storage along the annular inclined surface 426 of the inner annular surface 425.

[0063] In some embodiments of this utility model, reference is made to Figure 4 , Figure 6 The front side of the airbag front cavity 310 is provided with a rear storage chamber 340. The front side of the rear storage chamber 340 is connected to the second through hole 422 of the three-way chamber 420. In this way, the rear storage chamber 340 and the three-way chamber 420 can form a larger milk storage space, resulting in better milk expression.

[0064] In some embodiments of this utility model, the airbag membrane 130 is provided with a membrane insertion hole 133, and the membrane insertion hole 133 of the airbag membrane 130 is fitted into the rear side of the rear temporary storage chamber 340, which facilitates the fixed installation of the airbag membrane 130.

[0065] In some embodiments of this invention, a flared opening 450 is provided on the front side of the second component 400, and the first through hole 421 is located at the middle position on the rear side of the flared opening 450. A silicone flared cover 700 is provided on the flared opening 450, so that when the breast pump of this invention is in contact with the breast, the silicone flared cover 700 makes the breast more comfortable. The silicone flared cover 700 is fixed to the second component 400 and can be detached as a separate accessory, or it can be integrally formed with the second component 400.

[0066] In some embodiments of this utility model, the silicone speaker cover 700 is provided with petal massage protrusions 710 for massaging the breasts.

[0067] The breast pump according to a second aspect of the present invention includes the compact reclining breast pump according to the first aspect of the present invention described above.

[0068] The breast pump according to the present invention adopts the above-mentioned compact lying breast pump, which makes the structure of the breast pump compact and suitable for breast pumping in sitting and lying positions, thereby improving the user experience.
