Description

Electric breast pump

Technical Field

The utility model relates to a breast pump technical field, concretely relates to electronic breast pump.

Background

The breast pump can be used by lactating women in hospitals or families to suck breast milk out of the breast. After the breast pump is used for lactation, the congestion symptom can be relieved. If mastitis is encountered, breast milk may be drawn from the infected breast with a breast pump to assist in the treatment process. The breast pump can relieve pain and chap of the nipple and can expose a flat or depressed nipple. In addition, babies who have problems with sucking, cleft lips and palate, or who are born prematurely cannot feed directly, the breast pump also allows mothers to provide a way for such babies to enjoy breast feeding.

The control panel of the existing electric breast pump mainly adopts MCU control technology and adopts a 3.7V lithium battery or a 5V power adapter to provide power. The main control chip realizes the functions of simulating the milk sucking and the lactation promotion of the baby by controlling the working and stopping time of the vacuum pump and the electromagnetic valve. The human-computer interface is a liquid crystal screen/nixie tube/LED display, and the startup and shutdown, the working mode selection and the gear adjustment are realized through induction keys/mechanical keys.

The conventional main control chip control electromagnetic valve technology mainly controls the on/off of an MOS (metal oxide semiconductor) tube through an MCU (micro control unit), so as to control the power-on and power-off of a battery valve and further control the opening and closing of the battery valve. When the electromagnetic valve is opened, the MCU is required to control the MOS to be opened, and then the electromagnetic valve is electrified. After the coil inside the electromagnetic valve is electrified, a downward magnetic force can be generated, the valve metal column is pulled down, and then the valve of the battery valve is opened, so that the inside of the vacuum pump is communicated with the atmosphere, and the breast pump stops sucking. When the electromagnetic valve is closed, the MCU is required to control the MOS to be closed, and then the electromagnetic valve is powered off. The inside coil outage of solenoid valve back can not produce magnetic force, and the spring below the valve metal post can push back the metal post original position, and then makes the battery valve close, and then makes the inside and atmosphere of vacuum pump separate, begins to carry out the evacuation, and the breast pump begins to suck milk.

However, the above patents still have the following problems:

(1) When the breast pump sucks milk, the electromagnetic valve is in a stop working state that the electromagnetic valve is not electrified and the valve is closed; when the breast pump stops sucking, the electromagnetic valve is in a working state of being electrified and the valve is opened. Most breast pump products on the market at present are directly controlled to open the MOS tube for opening control of the electromagnetic valve, and the electromagnetic valve is directly electrified to have a high level. The control time is about 2 seconds at most each time, namely the solenoid valve works at full power within the two seconds. The solenoid valve of the breast pump works about 15 times in one minute, that is, the solenoid valve works for 30 seconds at full power in one minute. The solenoid valve is internally provided with a coil, and the coil is electrified to generate a large amount of heat per se and has large power consumption on a battery.
