[0029] like Figure 1-5 As shown, this application provides a breast pump, including a horn cover 1, which forms a receiving cavity 11. The receiving cavity 11 can fit and at least partially accommodate the breast without gaps, forming a sealed cavity.

[0030] One-way valve 3 is located at the constricted end of the horn cover 1, and one-way valve 3 is part of the cavity wall of the sealed cavity.

[0031] The breast collection shield 2, together with the horn cover 1, forms a breast collection cavity 23, which is connected to the sealed cavity through a one-way valve 3.

[0032] The negative pressure pump 6 is connected to the sealed cavity and is used to draw gas from the sealed cavity to create a negative pressure in the sealed cavity.

[0033] In this embodiment, the inner wall of the horn cover 1 can fit against the user's breast, and when the user's breast fits against the inner wall of the horn cover 1, the horn cover 1 and the breast collection cover 2 form a closed cavity, and the inside is in a sealed state. The breast collection cover 2 is provided with a liquid outlet 22, which is used to pour out the breast milk inside the breast collection cover 2. The liquid outlet 22 is in a sealed state when working.

[0034] By setting a one-way valve 3 and eliminating the three-way plastic part, when negative pressure is generated in the sealed cavity, it can prevent the breast milk in the milk collection chamber 23 from flowing back into the sealed cavity. The one-way valve 3 is a duckbill valve. Specifically, when negative pressure is generated in the sealed cavity, the air pressure inside the sealed cavity is lower than the air pressure outside, which will cause the one-way valve 3 to deform and close. At the same time, after the one-way valve 3 closes, it can also prevent gas leakage, increase airtightness, and improve the milk expression effect. When the negative pressure disappears, the one-way valve 3 will open again, and the expressed breast milk will flow from the one-way valve 3 into the milk collection cover 2.

[0035] During operation, the inner wall of the speaker cover 1 is first made to fit against the user's breast. Then, the negative pressure pump 6 is activated to extract the gas inside the sealed cavity. A negative pressure is formed inside the sealed cavity. When combined with the speaker cover 1, pressure is applied to the user's breast to squeeze out breast milk.

[0036] Compared to existing breast pumps, this application reduces the number of three-way valves, which not only simplifies the structure but also allows the negative pressure pump 6 to act directly on the sealed cavity, enhancing suction and thus improving the milk expression effect.

[0037] In one embodiment, a solenoid valve 8 is also included, which is connected to the sealed cavity and is used to cancel the negative pressure state inside the sealed cavity.

[0038] In this embodiment, the solenoid valve 8 is in a sealed state when it is not working. When it is working, the conducting end is connected to the outside, so that air is filled into the sealed cavity and the negative pressure inside the sealed cavity is released.

[0039] In one embodiment, a control mechanism is also included, comprising a control board 9 and at least one battery, the battery being electrically connected to the control board 9, and the control board 9 being electrically connected to the negative pressure pump 6 and the solenoid valve 8, respectively.

[0040] In this embodiment, the control board 9 can send control commands to the negative pressure pump 6 and the solenoid valve 8 to drive the negative pressure pump 6 and the solenoid valve 8 to work. By setting a number of buttons 512, each button 512 corresponds to an operation command.

[0041] By setting up storage batteries, the negative pressure pump 6 and the solenoid valve 8 can be powered. Two storage batteries are used, which increases the pump's operating time.

[0042] In one embodiment, the system also includes a power compartment 5, a negative pressure pump 6, a solenoid valve 8, and a control mechanism, all of which are located within the power compartment 5. The power compartment 5 is detachably connected to the breast cup 2.

[0043] In this embodiment, by separating the negative pressure pump 6, the solenoid valve 8, and the control mechanism from the milk collection chamber 23, the expressed breast milk can be prevented from affecting the negative pressure pump 6, the solenoid valve 8, and the control mechanism, thus preventing damage to the breast pump.

[0044] In one embodiment, the surface of the breast cup 2 is provided with a mounting hole 21, and a protruding ring 24 is provided around the mounting hole 21 on the inner wall of the breast cup 2. The power compartment 5 is installed at the mounting hole 21 through a connector 4, and the connector 4 is detachably connected to the power compartment 5.

[0045] In this embodiment, the mounting hole 21 is circular. Optionally, the mounting hole 21 can also be square or other irregular shapes. The shape of the convex ring 24 is consistent with the shape of the mounting hole 21, and the inner diameter of the convex ring 24 is consistent with the diameter of the mounting hole 21. The convex ring 24 and the mounting hole 21 form a mounting position. When the connector 4 is inserted into the mounting hole 21, the connector 4 and the convex ring 24 cooperate to make the power compartment 5 and the breast cover 2 tightly connected. The connector 4 is provided with an air extraction hole 41 and an air inlet hole 42. The air extraction hole 41 is connected to the negative pressure pump 6 through a pipe, and the air inlet hole 42 is connected to the solenoid valve 8 through a pipe. The shape and size of the connector 4 match the mounting hole 21, which can improve the sealing of the connection.

[0046] In one embodiment, the power compartment 5 includes a first half-shell 51 and a second half-shell 52. The first half-shell 51 and the second half-shell 52 are detachably connected. The connector 4 is provided with a plurality of buckles 43. The second half-shell 52 is provided with a plurality of slots 522 that match the buckles 43. When the buckles 43 are inserted into the slots 522, the connector 4 is connected to the second half-shell 52.

[0047] In this embodiment, the first half-shell 51 and the second half-shell 52 can be connected by bolts. Optionally, the connector 4 has four buckles 43 and four corresponding slots 522. When the buckle 43 is inserted into the slot 522, the connector 4 and the second half-shell 52 can be installed.

[0048] The second half-shell 52 has corresponding through holes 521 at the positions of the air extraction hole 41 and the air inlet hole 42.

[0049] In one embodiment, the side wall of the connector 4 is provided with an annular groove 44, and a sealing ring 441 is provided in the annular groove 44, with the sealing ring 441 protruding out of the annular groove 44.

[0050] In this embodiment, by setting a sealing ring 441, after the connector 4 is inserted into the mounting hole 21, the sealing ring 441 can abut against the inner wall of the convex ring 24. This not only improves the sealing performance of the connection, but also makes the power compartment 5 more stable to install and less likely to fall out of the mounting hole 21 due to the friction between the sealing ring 441 and the inner wall of the convex ring 24.

[0051] In one embodiment, the first half-shell 51 is provided with a plurality of buttons 512.

[0052] In this embodiment, different buttons 512 can send different control commands to the controller to achieve different functions;

[0053] Specifically, button 512 includes a power on / off button, a speed setting button, a pause button, and a mode switching button. The power on / off button is used to control the breast pump to start and stop. The speed setting button includes a "+" button for increasing the speed and a "-" button for decreasing the speed. The pause button is used to control the breast pump to stop working. The breast pump of this application has a massage mode, a milk expression mode, a stimulation mode, and an automatic mode. The mode switching button is used to switch between the four modes of the breast pump.

[0054] In one embodiment, the first half-shell 51 is provided with a display screen 511, which is electrically connected to the control board 9.

[0055] In this embodiment, the display screen 511 can display pressure, battery level, charging status, time, and gear information.
