[0024] like Figures 1 to 5 As shown, the utility model provides a wearable breast pump, which includes a breast shield 1, a milk storage shield 2 arranged on the breast shield 1, a milk storage chamber 3 formed by the inner wall of the milk storage shield 2 and the inner wall of the breast shield 1, a mainframe front shell 4 connected to the milk storage shield 2, at least two air pressure regulating spaces 5 formed by the outer wall of the milk storage shield 2 and the inner wall of the mainframe front shell 4, an air pump assembly 6 for generating negative pressure in the air pressure regulating space 5, a suction nozzle 7 arranged on the breast shield 1, and a connecting sleeve 8 located in the milk storage chamber 3 and sleeved on the outside of the suction nozzle 7, wherein the connecting sleeve 8 is respectively connected to the milk storage chamber 3, the suction nozzle 7 and the plurality of air pressure regulating spaces 5.

[0025] In actual use, the air pump assembly 6 is started and a negative pressure is generated in the air pressure regulating space 5. The negative pressure state is transmitted to the suction nozzle 7 connected thereto, so that the suction nozzle 7 maintains a negative pressure, which is convenient for the extraction of milk. The extracted milk flows through the suction nozzle 7 through the connecting sleeve 8 and flows into the milk storage chamber 3, which is used to store milk. The air pressure regulating space 5 of the utility model is set to one or more, which effectively utilizes the space while ensuring sufficient negative pressure or suction, reduces the volume of the air pressure regulating space 5 and the wearable breast pump, is easy to wear, and improves the practicality and utilization rate of the utility model.

[0026] Furthermore, the connecting sleeve 8 includes a sleeve portion 9 sleeved on the outside of the suction nozzle 7, an extension portion 10 connected to the sleeve portion 9, a first through hole 12 arranged through the sleeve portion 9 and a one-way valve 11 connected to the extension portion 10, the first through hole 12 is respectively connected to the hollow space of the sleeve portion 9 and a plurality of air pressure regulating spaces 5, and the hollow space of the sleeve portion 9 is connected to the one-way valve 11 via the hollow space of the extension portion 10.

[0027] In actual use, milk flows into the hollow space of the sleeve portion 9 and the hollow space of the extension portion 10 in sequence through the suction nozzle 7, and is finally discharged into the milk storage chamber 3 through the one-way valve 11. The sleeve portion 9 is directly sleeved outside the suction nozzle 7, and the suction nozzle 7 and the extension portion 10 are directly connected, so that milk is directly introduced into the milk storage chamber 3, and the one-way valve 11 is added to prevent the milk in the milk storage chamber 3 from flowing back. The one-way valve 11 can adopt an existing one-way control structure, and its function is the same or similar to that of the existing one-way control structure, which will not be repeated here. The connecting sleeve 8 is easy to install and connect with the suction nozzle 7 and the milk storage chamber 3.

[0028] Furthermore, the air pump assembly 6 includes an air pump body 14 arranged at at least two suction bags 13 and respectively connected to the multiple suction bags 13, the multiple suction bags 13 are interconnected and arranged one by one in the air pressure regulating space 5, the main engine front shell 4 covers the openings of the multiple suction bags 13, and the air pump body 14 is used to synchronously inflate or exhaust the multiple suction bags 13.

[0029] Specifically, the main body front shell 4 is provided with a plurality of second through holes 15 and a ventilating pipe assembly (not shown in the figure), and the plurality of second through holes 15 are respectively connected with the plurality of suction bags 13 in one-to-one correspondence; the ventilating pipe assembly can be inserted into the interior of the suction bags 13 through the plurality of second through holes 15, and the ventilating pipe assembly respectively connects the air pump body 14 with the interior of the plurality of suction bags 13. In actual use, the air pump body 14 extracts air from the suction bags 13 or blows air into the suction bags 13 through the ventilating pipe assembly, thereby causing the suction bags 13 to expand or contract, and the air pressure in the air pressure regulating space 5 is synchronously adjusted by the expanded or contracted suction bags 13, and then the air pressure change in the air pressure regulating space 5 is transmitted to the suction nozzle 7 through the connecting sleeve 8, thereby simulating the sucking effect of a baby and promoting lactation. The structure of the air pump assembly 6 is simple and compact. The gas pressure in the air pressure regulating space 5 is further adjusted by the volume change of the suction bag 13 in the air pressure regulating space 5. The pressure changes in multiple air pressure regulating spaces 5 are synchronized and transmitted to the suction nozzle 7 through the connecting sleeve 8, so that the air pressure in the suction nozzle 7 changes evenly, thereby improving the milk sucking experience and reducing pain.

[0030] Furthermore, the wearable breast pump also includes a plurality of limiting protrusions 16 arranged on the front shell 4 of the main unit, and the plurality of limiting protrusions 16 protrude into the plurality of air pressure regulating spaces 5 in a one-to-one correspondence; the opening of the suction bag 13 is clamped between the limiting protrusion 16 and the outer wall of the milk storage cover 2.

[0031] A limiting protrusion 16 is added, and the opening of the suction bag 13 is clamped between the limiting protrusion 16 and the milk storage cover 2. When the suction bag 13 expands or contracts, the air tightness at the opening of the suction bag 13 is good; and while the air tightness is improved, the suction bag 13 is not easy to shake or deflect, and the suction bag 13 has good stability after installation.

[0033] In actual use, the plurality of air pressure regulating spaces 5 are symmetrically arranged on the outer periphery of the suction nozzle 7 to achieve uniform adjustment of the air pressure in the suction nozzle 7. The integrally arranged suction bag 13 can be installed in the plurality of air pressure regulating spaces 5 at one time, further simplifying the installation steps of the suction bag 13.

[0034] Furthermore, the main engine front shell 4 is configured to be L-shaped, and one side of the main engine front shell 4 and the milk storage cover 2 enclose an air pressure regulating space 5 ; the air pump body 14 is installed on the other side of the main engine front shell 4 .

[0038] Furthermore, the air pump assembly 6 also includes a solenoid valve 19 for controlling the gas flow output by the air pump body 14 .

[0039] In actual use, the electromagnetic valve 19 controls the gas flow rate extracted or blown into the suction bag 13 by the air pump body 14, thereby achieving accurate milk suction.

[0040] Furthermore, the air pump assembly 6 also includes a battery 20 electrically connected to the air pump body 14 , and the battery 20 is used to supply power to the air pump body 14 .

[0041] In actual use, the air pump body 14 is powered by the battery 20, so that the utility model can be used without a power source, which is more portable and practical. The battery 20 and the solenoid valve 19 are both arranged on the main body front shell 4, and the solenoid valve 19 and the battery 20 are easy to install.
