A structure for removing residual breast milk from a breast pump

Abstract

This utility model relates to the field of breast pump technology, and more particularly to a structure for removing residual breast milk from a breast pump. The structure includes a body with a top cover on the front upper part. The top cover is fixed to the edge of the body with four sets of screws. A button bracket is located at the center of the top cover, and button switches are distributed on the button bracket. A circuit board is fixedly mounted on the body, with the button switches aligned with the button area of ​​the circuit board. When the machine finishes pumping, it continues to operate for a short period to ensure that any residual milk in the nipple channel is smoothly pumped into the bottle (especially ensuring the milk level in the bottle is above the lower nipple spout valve). This also allows for intermittent pauses to prevent excessive milk accumulation in the nipple channel during pumping, thus avoiding leakage.

Description

Technical Field

[0001] This utility model relates to the field of breast pump technology, and in particular to a structure for removing residual breast milk from a breast pump. Background Technology

[0002] With the improvement of living standards, many mothers now use electric breast pumps. This invention mainly targets wearable breast pumps, which have a major drawback: after pumping, when preparing to remove the pump, some expressed milk remains in the nipple canal (the three-way connector in the pump's structure), especially for mothers with high milk production. This forces mothers to lean forward forcefully to remove the machine without leaking milk. After removal, they then have to figure out how to empty the milk, leading to waste and the possibility of accidentally spilling milk from a bottle. Utility Model Content

[0033] It should be further noted that the push-button switch 14 is fixed to the push-button bracket 13 by screws, and the push-button bracket 13 is fixed to the top cover 11 by screws.

[0034] It should be further noted that two circuit board mounting holes are provided at the edge of the circuit board 12, and the end of the body 1 near the circuit board 12 is fixedly connected by screws to the circuit board mounting holes.

[0035] It should be further noted that the machine body 1 has a pump slot at the installation position of the air pump 15, and the air pump 15 and the pump slot are interlocked.

[0036] It should be further noted that the main body 1 has a battery slot at the installation position of the battery 2, and the battery 2 and the battery slot are interlocked.

[0037] It should be further noted that the end of the body 1 is provided with a concave part, and the edge of the bottle 3 is provided with a protrusion part, and the protrusion part and the concave part are interlocked.

[0039] Working method: The working process of a regular breast pump: Press the button switch, the program on the circuit board starts, and the negative pressure air pump is turned on. At this time, the air pump starts to suck air. The solenoid valve is closed, and the air does not flow. The air pump sucks the air out of the silicone cylinder through the silicone hose, and the inside of the silicone cylinder becomes negative pressure. The silicone cylinder deforms and contracts. At this time, the user's breast is pressed tightly against the breast pump. Due to the deformation and contraction of the silicone cylinder, negative pressure is generated in the three-way valve, which sucks the breast milk into the three-way valve. After a few seconds, the air pump stops sucking air under negative pressure. The program will open the solenoid valve connected to the air pump, allowing the silicone cylinder to circulate with the outside air. Without negative pressure, the silicone cylinder will return to its original shape. Through the restoration of the silicone cylinder, positive pressure is generated in the three-way valve, which forces the air and breast milk in the three-way valve into the bottle through the duckbill valve.

[0040] New addition: Add a normally closed solenoid valve connected to the tee. By switching the solenoid valve on and off, the negative pressure in the tee during operation can be changed.

[0041] New workflow: Normal operation is the same as a regular breast pump, with the solenoid valve always in the closed state. However, during the last two pump suction and deflation cycles before the end of the entire operation, the newly added solenoid valve will open when the pump is suctioning, allowing air to circulate between the three-way valve and the outside air. Without negative pressure, the pump will not continue to suck milk. When deflation occurs, the solenoid valve will close, and the duckbill valve will open under pressure through the recovery of the silicone cylinder, pressing the remaining breast milk into the bottle. After pressing the pause or power button, the pump will continue to operate for two more pump suction and deflation cycles, repeating the above-mentioned new workflow.

[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
