[0028] The present application provides an integrated breast pump, comprising a milk receiving bowl and a trumpet cover arranged at the mouth of the milk receiving bowl, the trumpet mouth of the trumpet cover extends toward the inside of the milk receiving bowl to form a tubular circulation part integrally formed with the trumpet cover, a first milk outlet is formed on the side wall of the circulation part, an elastic diaphragm integrally formed with the circulation part is arranged inside the circulation part, the first milk outlet is arranged between the elastic diaphragm and the trumpet mouth, the end of the circulation part is tightly matched with the milk receiving bowl, the elastic diaphragm forms an air cavity at one end of the circulation part away from the trumpet mouth, the air cavity generates suction in the circulation part close to the trumpet mouth, and the milk receiving bowl is provided with a connecting part for externally connecting an air pump which cooperates with the air cavity.

[0029] Implementation example Figures 1 to 7 As shown, an integrated breast pump comprises a milk receiving bowl 1 and a trumpet cover 2 covering the mouth of the milk receiving bowl 1. A trumpet mouth 2.5 of the trumpet cover 2 extends toward the inside of the milk receiving bowl 1 and a tubular flow portion 2.1 integrally formed with the trumpet cover 2 is formed.

[0030] Furthermore, the side wall of the circulation part 2.1 is formed with a first milk outlet 2.2 for sucking out milk and flowing it into the milk receiving bowl 1. The end of the first milk outlet 2.2 may be provided with an integrated or split check valve 2.3. This embodiment provides two check valve 2.3 solutions, one of which is as follows: Figure 7 The split type detachable duckbill valve is installed at the end of the first milk outlet 2.2 as shown, and the other is as shown Figure 3 , 5, 6 and the elastic opening and closing piece integrally arranged with the first milk outlet 2.2.

[0031] Furthermore, an elastic diaphragm 2.4 integrally formed with the circulation part 2.1 is provided inside the circulation part 2.1, and the first milk outlet 2.2 is provided between the elastic diaphragm 2.4 and the bell mouth 2.5. The end of the circulation part 2.1 is tightly matched with the milk receiving bowl 1, and the elastic diaphragm 2.4 makes the end of the circulation part 2.1 away from the bell mouth 2.5 cooperate with the milk receiving bowl 1 to form an air cavity 2.6, and the milk receiving bowl 1 is provided with a connecting part 1.1 for connecting an external air pump that cooperates with the air cavity 2.6. The air pump sucks air into the air cavity 2.6 through the connecting part 1.1 to deform the elastic diaphragm 2.4, and then generates suction on the circulation part 2.1 close to the bell mouth 2.5 to achieve the extraction of breast milk.

[0032] Specifically, a connecting portion 1.2 extending toward the circulation portion 2.1 is provided inside the milk receiving bowl 1, and the connecting portion 1.2 is tightly plugged into the air cavity 2.6 of the circulation portion 2.1, and an abutting portion 2.7 abutting against the connecting portion 1.2 is provided inside the air cavity 2.6.

[0033] Specifically, the end of the circulation part 2.1 is provided with an avoidance groove 2.8 which matches the shape of the communication part 1.1 when plugged and installed with the connection part 1.2.

[0034] Specifically, the elastic membrane 2.4 is provided with a main structure extending toward the air cavity 2.6 for easy elastic deformation, and the elastic deformation of the main structure generates negative pressure in the circulation portion 2.1 to achieve milk suction. In this embodiment, two main structures of the elastic membrane 2.4 are provided, one of which is as follows: Figure 6 As shown, the main structure of the elastic membrane 2.4 is stepped, and under the action of the air pump, it can perform elastic expansion and contraction movement along the extension direction of the main structure, thereby simulating the sucking movement; another example is Figure 1 , 3 As shown in Figures 5 and 7, the main structure of the elastic diaphragm 2.4 is in a convex shape of three equal parts, and a spaced cavity is formed between each of the three equal parts. The main structure is provided with an opening on the side close to the bell mouth 2.5. The spaced cavity can be regularly contracted by the action of an air pump, and then the opening on the side close to the bell mouth 2.5 can be regularly opened and closed, simulating a sucking movement to facilitate milk discharge for the user.

[0035] Furthermore, the milk receiving bowl 1 is provided with a second milk outlet 1.3 for pouring milk out of the milk receiving bowl 1 in a direction away from the first milk outlet 2.2, and the horn cover 2 is provided with a mounting plug 2.9 for blocking the second milk outlet 1.3. The mounting plug 2.9 comprises a plug body 2.9.1 for blocking and a mounting portion 2.9.2 protruding toward the second milk outlet 1.3 and plugged into the second milk outlet 1.3, the mounting portion 2.9.2 is a C-shaped structure arranged along the circumference of the mounting plug 2.9, and an exhaust groove 2.9.3 is formed on the mounting portion 2.9.2 so that the mounting portion 2.9.2 cannot be closed. When the mounting portion 2.9.2 is tightly inserted into the second milk outlet 1.3, the opening of the exhaust groove 2.9.3 exhausts the second milk outlet 1.3 on which the mounting plug 2.9 has been installed, which not only ensures that milk will not leak out, but also ensures that the air pressure is discharged smoothly without affecting the milk suction effect.
