The communicating part comprises a converging channel communicated with the breast pump main body, a milk inlet channel communicated with the milk sucking part and an air suction channel communicated with the space internal pressure changing device, wherein the milk inlet channel and the air suction channel are respectively communicated with the converging channel, the air suction channel is provided with a containing cavity for installing a suction deformation bag, and the telescopic end part of the suction deformation bag is arranged towards the connecting end of the air suction channel and the converging channel. The diameter of the accommodating cavity is larger than that of the air suction channel, and the volume of the suction deformation bag in the 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 air 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 opening and closing of the vacuum pump and the electromagnetic valve, wherein the supporting seat is provided with an air suction port and an air inlet, the air suction port is communicated with the air suction end of the vacuum pump and is in sealing fit with each other, the air inlet is communicated with the working end of the electromagnetic valve and is in sealing fit with each other, the opening end of the suction deformation bag is sleeved on the air suction port and the air inlet of the supporting seat, and the opening end of the suction deformation bag is in sealing fit with the supporting seat.

In the electric breast pump, due to the limitation of the volume of the main body of the breast pump and the production process limitation of the air pump, a unidirectional air pump with smaller volume is generally adopted, namely, the motor inside the air pump can only rotate in one of the clockwise direction or the anticlockwise direction and can not rotate reversely.

In the reference 1, the vacuum pump of the pressure changing device can alternately generate the negative pressure state and the atmospheric pressure state of the open end sleeve. When the vacuum pump operates and the electromagnetic valve is switched to the pressure maintaining station, the opening end sleeve presents a negative pressure state to realize the milk sucking function; 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 reference 1 is a unidirectional air pump, and in addition, referring to fig. 1 of the specification of the reference 1, the milk sucking part is provided with 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 passage which is used for driving the massage convex points to actively bulge, and the breast pump cannot realize the active massage function.

The massage salient points act as follows: when the vacuum pump operates and the electromagnetic valve is switched to the pressure maintaining station, the opening end sleeve presents a negative pressure state, and the massage salient points are attached to the milk sucking part in the negative pressure state; 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, the massage salient points recover the initial protruding state by means of the material and structural characteristics of the massage salient points, the extrusion contact of the breasts is realized, and obviously, the massage force and the massage effect of the passive massage mode do not meet the requirements, and certain limitations exist.

The breast pump assembly consists of a breast pump sleeved in a breast pump accommodating cavity, a buckling position which is formed by outwards forming the opening end of the breast pump and is used for buckling the top end of the breast pump accommodating cavity, outwards protruding a tiny protruding part and forming a concave position, a basin bottom concave cavity which is formed by upwards and inwards concave the whole bottom of the breast pump to enable a cross rod of an inverted T-shaped connecting rod to be tightly attached and positioned, an assembling hole site which is penetrated through the concave cavity and is formed upwards at the center part of the basin bottom concave cavity, a connecting rod which is arranged in an inverted T-shaped manner, a convex column which is formed at the top and the middle of the connecting rod to enlarge the diameter respectively, and a first clamping groove which is used for grooving and nesting at the end part of a handle and a second clamping groove which is used for nesting at the assembling hole site at the bottom of the breast pump are formed; the breast pump connecting rod is sleeved from the assembly hole at the bottom of the breast pump and then is arranged at the opening at the upper end of the breast pump assembly. A plurality of concave cavities protruding to form bubble-shaped thin walls are formed on the horn wall of the breast pad, and the edge of the horn mouth of the breast pad is outwards coated with a wrapping ring for sleeving the horn mouth end of the breast pump cover; the bubble-shaped thin wall massages the breast under the action of the gas and promotes the secretion of milk. The breast pad is formed by forming a plurality of loudspeaker walls which are formed by concave cavities with bubble-shaped thin walls to integrally cover the inner lining of the outer wall of the breast shield, and the breast pad is provided with air holes and integrally cover. The inner liner comprises an outer liner, and an air guide groove formed between the inner liner and the outer liner.

In the reference 2, the bubble-like thin wall (equivalent to the massage cavity) presses the breast pool inward and the rebound release action cooperates with the pressing and release action of the air bag (equivalent to the suction bowl).

The problem is that the bubble-shaped thin wall cannot independently perform the function of squeezing the breast, and the operation of the air bag is necessary to be matched, so that certain limitation exists.

Therefore, further improvements are needed.
