Problems solved by technology

[0002] Diaphragm pumps are commonly used in existing breast pumps. The high-frequency breast pumping mode and high-frequency lactation mode can produce low suction (compared to piston pumps), low breast pumping efficiency, and poor comfort.
All diaphragm pumps cannot provide high efficiency due to the working principle of pumping and exhausting air, and have the characteristics of maintaining a negative pressure platform and a negative pressure gradual drop waveform, resulting in low efficiency and poor comfort for breast pumping
Diaphragm pump can’t blow air in the opposite direction to quickly inflate and reset the diaphragm, which will affect the high-frequency milk pumping and lactation mode of the diaphragm pump breast pump. Low (compared to piston pumps)
[0003] At present, the total speed ratio of the piston pump transmission mechanism of breast pumps on the market is relatively low, all of which are below 18. When the piston end needs a larger piston thrust, a larger motor torque is required, thereby increasing the volume and cost of the same type of motor and motor noise
The total speed ratio of the piston pump transmission mechanism of the breast pump is below 18. Considering the size of the motor and the reasonable cost, it is impossible to provide sufficient air volume at the piston pump end to pump air at the three-way diaphragm end, resulting in the connection of the breast shield. The volume change and negative pressure generated by the three-way diaphragm end are strictly limited, and there is a lack of adjustment margin, which is not conducive to the stability of the entire breast pump system
Moreover, there are great limitations on the initial volume setting of the three-way tube and the diaphragm, which will ultimately affect the efficiency and comfort of the three-way tube for breastfeeding

Abstract

The invention discloses a method for improving the negative pressure of a breast pump, a motor for controlling the breast pump and a transmission mechanism of the motor, the transmission mechanism is connected with the motor and a piston pump, the total speed ratio of the transmission mechanism is 20-35, the torque of the motor is 130-300 g.cm, the rotating speed of the motor is 4000-8000 revolutions per minute, and the negative pressure of the breast pump is increased. The highest negative pressure generated by the piston pump is 1.2-1.6 times of the highest negative pressure generated by the three-way diaphragm. The invention provides a method capable of improving the negative pressure of the three-way diaphragm end of a breast pump.

Description

technical field [0001] The invention belongs to the field of breast pump preparation, and in particular relates to a method for improving the negative pressure of a breast pump. Background technique [0002] Existing breast pumps generally use diaphragm pumps. The high-frequency milk pumping mode and the high-frequency milking mode can generate low suction (compared to piston pumps), low breast pumping efficiency, and poor comfort. All diaphragm pumps cannot provide high efficiency due to their working principle of pumping and deflating, and have the characteristics of maintaining a negative pressure platform and a negative pressure gradient waveform, resulting in low pumping efficiency and poor comfort. The diaphragm pump cannot reverse the air to quickly inflate and reset the diaphragm, which will affect the high-frequency pumping and lactation mode of the diaphragm pump. Low (vs. piston pump). [0003] At present, the total speed ratio of the piston pump transmission me...
