The diameter of the accommodating cavity is larger than that of the air suction channel, and the volume of the suction deformation bag in an inflated state is matched with that of the accommodating cavity. The space internal pressure changing device comprises a supporting seat, a vacuum pump (equivalent to a milk sucking pump) and an electromagnetic valve (equivalent to a milk sucking electromagnetic valve) which are arranged on the supporting seat, and a control unit capable of controlling the vacuum pump and the electromagnetic valve to be opened and closed.

In the electric breast pump, because of the volume limitation of the breast pump host and the production process limitation of the air pump, a one-way air pump with a small volume is generally adopted, namely, the motor in the air pump can only rotate in one of a clockwise direction or a counterclockwise direction and can not rotate reversely.

In reference 1, the vacuum pump of the pressure changing device can alternately generate a negative pressure state and an atmospheric pressure state in the open end sleeve. When the vacuum pump operates and the electromagnetic valve is switched to the pressure maintaining station, the opening end sleeve is in a negative pressure state to realize the milk sucking function; and when the vacuum pump stops running and the electromagnetic valve is switched to the pressure relief station, the opening end sleeve is in a released atmospheric pressure state. Therefore, the vacuum pump in the comparison document 1 is a one-way air pump, and referring to fig. 1 of the specification of the comparison document 1, the milk sucking part of the vacuum pump has massage convex points.

The problem is that the breast pump body and the pressure changing device are not provided with a pneumatic device or an air channel which is used for driving the massage salient points to actively bulge, and the breast pump can not realize the active massage function.

The action of the massage salient points is as follows: when the vacuum pump operates and the electromagnetic valve is switched to the pressure maintaining station, the opening end sleeve is in a negative pressure state, and the massage salient points are attached to the milk sucking part in the negative pressure state; vacuum pump bring to rest, when the solenoid valve switches to the pressure release station, the opening pot head was in the atmospheric pressure state of release, and the massage bump relies on the material of self and structural characteristic to resume initial salient state, realizes the compressive contact to the breast, and obviously, the massage dynamics and the massage effect of this kind of passive massage mode are all unsatisfied the requirement, have certain limitation.

Comparison document 2: chinese patent document No. CN201987937U discloses a manual massage breast pump, comprising: a bottle body connected with the corresponding interface part of the breast pump assembly, a breast pump upper cover, a handle, a breast pad sleeved with a breast shield of the breast pump and forming an air guide groove between the two, wherein the breast pump assembly is provided with a bottom opening part in threaded connection with the mouth end of the bottle body at the bottom, a holding cavity formed at the central part of the breast pump, an annular duckbill valve sleeve communicated with the holding cavity at the bottom of the holding cavity in a protruding way, a duckbill valve sleeved on the outer wall of the annular duckbill valve sleeve, a breast pump assembly sleeved in the holding cavity from bottom to top, an air bag, a support piece connected with the handle and a rotating shaft at the top end of the support piece are respectively arranged on the two side walls of the breast pump holding cavity in an upward inclined protruding way, a pipeline communicated with the breast pump holding cavity and an outward protruding way and a breast shield with a trumpet-shaped opening formed at the end of the pipeline, a breast pump upper cover buckled on the top opening of, An air hole arranged on the breast pump cover and an air pipe passing through the air holes of the upper cover and the air bag of the breast pump are respectively connected with the air guide groove between the breast pump cover and the breast pad. The breast pump assembly consists of a breast pump sleeved in a breast pump accommodating cavity, a buckling position formed by respectively outwards forming the opening end of the breast pump and used for buckling the top end of the breast pump accommodating cavity and outwards convexly forming a tiny protruding part to form a bending concave position, a basin bottom concave cavity formed by integrally inwards recessing the bottom of the breast pump to form a transverse rod for closely positioning the inverted T-shaped connecting rod, an assembling hole position communicated with the concave cavity, a connecting rod arranged in the inverted T shape, a convex column formed by respectively forming the top and the middle part of the connecting rod to enlarge the diameter to form a first clamping groove for nesting the end part of the handle and a second clamping groove for nesting the assembling hole position of the bottom of the breast pump; the breast pump connecting rod is sleeved in the bottom assembly hole of the breast pump and then is arranged at the opening at the upper end of the breast pump assembly. The bellmouth edge of the breast pad is coated outwards to form a wrapping ring for sleeving the bellmouth end of the breast shield; the bubble-shaped thin wall massages the breast under the action of air, and the secretion of milk is promoted. The breast pad is formed by a plurality of horn walls which are formed by concave cavities which are protruded to form bubble-shaped thin walls, and the horn walls wholly cover the inner lining of the outer wall of the breast shield, are provided with air holes and wholly cover the breast shield. The outer lining of the inner lining, and the air guide groove formed between the inner lining and the outer lining of the breast pad.

In the comparison document 2, the bubble-shaped thin wall (equivalent to a massage chamber) presses the breast milk pool inward and the rebound release action is coordinated with the pressing and release action of the air bag (equivalent to a suction bowl).

The problem is that the bubble-shaped thin wall can not perform the function of pressing the breast alone, and the operation of the air bag is matched, so that certain limitation exists.

Therefore, further improvements are needed.
