A compact reciprocating suction device and breast pump

Abstract

The invention discloses a reciprocating suction device and a breast pump with a compact structure, which are applied to the field requiring small displacement suction vacuum, which uses a power motor unit for providing the original rotational torque and a power motor unit for converting the power into The cylinder driving unit whose internal volume is deformed to output suction is arranged in parallel on the same side of the gear transmission unit used for decelerating and reversing the original torque and is connected with it, and is designed by integrating the gear transmission unit with the synchronous belt transmission mechanism In the same gear box, while realizing the functions of large suction and high efficiency; compared with the existing technology of the same level, the volume can be reduced by half, and the purpose of portability is realized; the structure is firm and reliable, and multiple shock absorption and noise reduction designs are applied to achieve a quiet effect.

Description

technical field [0001] The invention relates to a reciprocating suction device with a compact structure and a breast pump, in particular to an electric suction device with a compact structure which generates suction through the reciprocating motion of a cylinder piston and a breast pump using the suction device. Background technique [0002] The reciprocating electric suction device (cylinder type electric suction device) is widely used in medical, health care, beauty and other fields that need to generate a small displacement vacuum; for example, the cylinder type breast pump, which uses the reciprocating electric suction device The generated suction collects the breast milk accumulated in the mammary gland to feed the baby, and the characteristics of the intermittent suction effect due to the reciprocating motion of the cylinder piston of the reciprocating electric suction device can be used to simulate the periodicity of the baby sucking breast milk. The suction and disch...

AI Technical Summary

Problems solved by technology

The plastic bowl type is mainly used for the manual type. The plastic bowl is deformed by pinching or pulling the lever to generate a vacuum, the suction is small, and the breast pumping effect is unreliable.

The vacuum pump type is used in electric breast pumps. Its small size is the main advantage, but the suction volume is small, and it depends on the accumulation of vacuum to achieve suction, so the efficiency is low and the suction comfort is not good.

Cylinder breast pumps have large suction volume, strong suction, high efficiency, and good comfort, but the structure is complex

The cylinder-type electric suction device inside is often bulky and inconvenient to carry, and mothers often go out or work when pumping milk, so the breast pump must truly meet the requirements of breastfeeding mothers. Ideal for large suction, high efficiency, and small size

Since the development of breast pump technology, the basic elements have been finalized. The more challenge is how to achieve the smallest volume while giving greater suction and efficiency. A further challenge is to achieve low noise, no interference, and a reliable service life.
