[0044] Furthermore, the front shell 1 of this invention has a front shell connecting part 11 on its inner rear end, and the front shell connecting part 11 has a fixing groove 12. The front side of the rear shell 2 has a connecting seat 25 that mates with the front shell connecting part 11, and the connecting seat 25 has a fixing buckle 251 that mates with the fixing groove 12. When the front shell and the rear shell are connected and fixed, the fixing buckle 251 can be inserted into the fixing groove 12, making the front shell and the rear shell more securely fixed.
[0045] Furthermore, the front of the bra 60 of this invention is provided with a door-shaped frame 601, and a front sealing groove 52 is provided on the door-shaped frame 601. The door-shaped frame 601 can effectively enhance the strength of the seal. A connecting part 611 is provided between the milk suction channel 61 and the milk cap 62, and a lower sealing groove 54 is provided on the outer wall of the connecting part 611. The size of the door-shaped frame 601 is approximately the same as the size of the rear opening 22 of the receiving cavity 21, and the size of the connecting part 611 is approximately the same as the size of the lower opening 23 of the receiving cavity 21. The lower sealing groove 54 is provided on the connecting part 611 so that it does not affect the deformation of the deformable structure 63, nor does it deform the milk cap 62.
[0046] Furthermore, the lower sealing ring 53 of the lower opening 23 of this invention is further provided with a lower rear shell receiving cavity 24 for inserting the milk cap 62. The upper part of the lower rear shell receiving cavity 24 communicates with the receiving cavity 21, and the lower sealing ring 53 is disposed between the lower rear shell receiving cavity 24 and the receiving cavity 21. Supporting edges 240 can also be provided on both sides between the lower rear shell receiving cavity 24 and the receiving cavity 21 below the lower sealing ring 53. The supporting edges 240 can support the lower sealing ring 53 and prevent it from deforming. The lower sealing ring 53 and the two supporting edges 240 can separate the lower rear shell receiving cavity 24 from the receiving cavity 21, so that the milk cap 62 located in the lower rear shell receiving cavity 24 will not deform when the air pressure chamber 7 is deformed by pressure.
[0047] Furthermore, the breast shield 60, milk suction channel 61, deformable structure 63, door frame 601, connecting part 611, milk cap 62, and one-way valve 64 of this utility model are integrally molded from flexible materials, such as silicone or rubber. This makes the breast shield 60, milk suction channel 61, deformable structure 63, door frame 601, connecting part 611, milk cap 62, and one-way valve 64 a single integrated structure, reducing the number of parts compared to existing breast pumps.
[0048] Furthermore, the rear shell 2 of this utility model includes a rear shell bottom plate 201, a rear shell rear panel 202 is provided on the rear side of the rear shell bottom plate 201, a rear opening 22 is provided on the rear shell rear panel 202, and a rear panel groove 2021 is provided on the front edge of the rear shell rear panel 202, and the upper rear end of the front shell can be inserted into the rear panel groove.
[0049] Furthermore, the rear shell 2 of this invention has a receiving cavity shell 203 protruding towards the front shell, forming a receiving cavity 21 within the receiving cavity shell 203. The electric air pump assembly 3 includes an air pump 31, a battery 32, and a solenoid valve 33 located on both sides of the receiving cavity shell 203. The receiving cavity shell 203 has an air intake hole 204, and one end of the air pump 31 communicates with the air intake hole 204. Compared to existing breast pumps, this design effectively utilizes the breast pump space, resulting in a smaller overall size.
[0050] Furthermore, the milk cap 62 of this utility model has an internal thread, and the milk storage container 8 can be directly used with a nipple to replace an ordinary baby bottle, realizing the multi-functional use of the breast pump and saving budget.
[0051] In some alternative embodiments, when the milk cap 62 is made of a flexible material, a hard rubber ring is provided on the outside of the milk cap 62 to facilitate the connection between the milk storage container 8 and the milk cap 62, thereby increasing the overall rigidity of the milk cap and facilitating the fixed connection between the milk storage container and the flexible milk cap.
[0052] like Figure 14 As shown, the switch assembly 4 of this utility model includes a control circuit board 41 inside the front shell 1 and a rocker switch 42 connected to the control circuit board. A rocker body 43 is connected to the outside of the rocker switch 42. A rocker annular groove 44 is provided on the side wall of the rocker body 43. A sealing silicone ring 45 is sealed inside the rocker annular groove 44. A decorative cover 46 is provided on the outside of the sealing silicone ring 45.
[0053] Compared to existing breast pumps, this invention uses a rocker switch 3 and a rocker body 4 in conjunction with a control circuit board 2. This makes the rocker switch assembly of this invention smaller in size, taking up less space in the breast pump, which is beneficial for assembly into the breast pump and further reduces the size of the breast pump.
[0054] Furthermore, the inner wall of the decorative cover 46 is provided with a connector 461, which passes through the sealing silicone ring 45 to fix the rocker body 43, the sealing silicone ring 45, and the decorative cover 46 to the front shell 1. The sealing silicone ring 45 forms a seal between the rocker body and the breast pump housing, and between the decorative cover and the breast pump housing. Compared with existing breast pumps, the waterproof function of the main unit switch is improved.
[0055] Furthermore, a waterproof annular protrusion 451 is provided on the outer wall of the sealing silicone ring 45. The waterproof annular protrusion 451 fits tightly against the inner side of the decorative cover 46 to prevent water from entering the breast pump from between the sealing silicone ring 45 and the decorative cover 46, thus achieving a better sealing and waterproof effect. The sealing silicone ring 45 has a silicone ring hole 451 for the connector 461 to pass through. This achieves full waterproofing of the entire machine.
[0056] Furthermore, a light-blocking bracket 47 is provided between the control circuit board 41 and the front shell 1. The light-blocking bracket 47 can prevent light leakage and play a role in protecting privacy.
[0057] The breast pump provided by this utility model is a wearable integrated breast pump. It adopts an integrated breast shield unit, which makes the breast pump have fewer parts, simpler to assemble, smaller in size, easier to disassemble and clean, and easier to carry and transport compared to existing breast pumps.
[0058] The rear shell of this breast pump is sealed to the integrated bra unit through a sealing structure, which makes the air pressure chamber formed between the integrated bra unit and the rear shell very well sealed, effectively improving the working efficiency of the breast pump.
[0059] The milk storage container and the cap of this breast pump are detachably connected. The milk storage container can be directly used with a nipple to replace an ordinary baby bottle, realizing the multi-functional use of the breast pump and saving budget.
[0060] This invention relates to a breast pump by setting a deformation structure at the upper and rear ends of the milk suction channel, allowing the electric air pump assembly to be located on the left and right sides of the receiving cavity shell. Compared to existing breast pumps, this design can further save internal space.
[0061] The breast pump of this invention uses a rocker switch and a rocker body in conjunction with a control circuit board. This makes the rocker switch assembly of this invention smaller in size and occupies less space in the breast pump, which is beneficial for assembly into the breast pump and further reduces the size of the breast pump.
