Electric breast pump

Abstract

The invention relates to an electric breast pump which comprises a main machine, an air pipe, a tee assembly, a milk bottle and a breast pumping cover, wherein the tee assembly comprises a first passage, a second passage and a third passage which are communicated mutually, the breast pumping cover and the milk bottle are detachably connected with the first passage and the second passage respectively, a separation plate is arranged at the joint of the third first passage and the first passage and the second passage, a through hole is formed in the separation plate, a milk overflow prevention silicone valve is arranged at the through hole, a tee cover is inserted into the third passage, a space is arranged between the tee cover and the separation plate, a venthole is formed in the tee cover and connected with an air pipe joint, the air pipe joint is connected with the main machine by the air pipe, and the milk overflow prevention silicone valve is communicated with the air pipe. According to the electric breast pump, all the parts can be detached, cleaning is convenient, and the safety and the sanitation of the breast pump are ensured; milk can be effectively prevented from flowing back into the air pipe, at the same time, pumping force can be transmitted to the breast without any attenuation, and effective vibratory massage and rapid milk pumping functions are realized; the air tightness is good, the joint is firm, and the milk pumping effect is further improved.

Description

technical field [0001] The invention relates to the field of maternal and infant products, in particular to an electric breast pump. Background technique [0002] A breast pump is a kind of maternal and infant product used to express breast milk. When the baby cannot directly suck the breast milk, the breast milk can be expressed through a breast pump to ensure breast feeding. There are two types of breast pumps: electric and manual. Wherein, the existing electric breast pump uses the negative pressure generated by the air pump or the motor for suction, and the suction force indirectly acts on the breast. At present, the milk of some electric breast pumps on the market will be sucked into the trachea and enter the host, causing a series of after-sales problems such as the burnout of the host. Although another part of the electric breast pump has an isolation device, although the isolation device plays a role in isolating the milk from returning to the trachea, the isolati...

AI Technical Summary

Problems solved by technology

The milk of some electric breast pumps currently on the market will be sucked into the trachea and enter the host, causing a series of after-sales problems such as the burnout of the host

Although another part of the electric breast pump has an isolation device, although the isolation device plays a role in isolating the milk from flowing back into the trachea, the isolation device limits the pressure and frequency of breastfeeding. The negative pressure of the vacuum pump of a common breast pump can reach 500mmHg. However, due to the influence of the isolation device and loss, the frequency and negative pressure finally transmitted to the breast are greatly weakened

When the puerpera needs greater suction during use, the suction of the existing electric breast pump cannot meet the requirements of the puerpera
