[0059] When the milk storage container 1 is connected with the connecting piece 2, the second butt joint end 12 of the milk storage container 1 is aligned with the connecting piece opening 226 of the connecting piece 2 and is inserted. Due to the chamfered setting of the second matching part 126 and the second fixing part 2211, the milk storage container 1 can be more easily inserted into the butt joint end inner cavity 221, and with the insertion of the milk storage container 1, the chamfer of the first fixing part 229 is in contact with the chamfer of the second matching part 126, gradually making the fixed end 2214 rotate outward, when the first matching part 125 of the milk storage container 1 extends into the limiting cavity 228 and abuts against the limiting cavity 228, the movable end 227 is automatically rotated back to the initial state due to the elastic effect of the plastic material, at this time, the first fixing part 229 on both sides abuts against the second matching surface 124 respectively, preventing the milk storage container 1 from moving away from the connecting piece 2, thereby realizing the connection of the milk storage container 1 and the connecting piece 2. When it is needed to disassemble the milk storage container 1, the user only needs to press the pressing part 2215 into the avoiding cavity 2216, at this time, the fixed end 2214 will also rotate outward, at this time, the first fixing part 229 will be separated from the second matching part 126, thereby enabling the milk storage container 1 to be easily taken out.

[0060] Embodiment three:

[0061] Please refer to Figure 12 The utility model also proposes a breast pump, wherein it also comprises a breast pumping assembly 3 for pumping milk, the breast pumping assembly is equipped with a breast pumping channel, the connecting piece 2 is also equipped with a conveying channel in communication with the connecting piece opening 226, the breast pumping assembly 3 is connected with the connecting piece 2, the breast pumping assembly 3 functions to suck milk through the breast pumping channel and convey it into the milk storage container 1 through the conveying channel.

[0062] The utility model sets the movable end 227 for fixing the milk storage container 1 on the connecting piece 2, and the movable end 227 is opened and closed, so that the user only needs to simply open the movable end 227 to realize the installation or separation of the milk storage container 1, which not only simplifies the operation process of the user, but also shortens the time required for disassembling the milk storage container 1 each time. Further, the utility model sets the breast pumping assembly 3 to realize the function of pumping milk, thereby ensuring the convenience of collecting milk. Further, the utility model sets the breast pumping channel on the breast pumping assembly 3, sets the conveying channel in the connecting piece 2, and makes the breast pumping channel in communication with the conveying channel, which enables the breast pump to continue conveying the milk into the milk storage container 1 through the conveying channel after pumping the milk through the breast pumping assembly 3, thereby further improving the convenience and hygiene of collecting milk.

[0063] Embodiment four:

[0064] Please refer to Figure 13The breast pump in the embodiment is similar to that in Embodiment Three, and the difference is that the movable end 227 is used in a rotating mode to realize the installation or separation of the milk storage container 1.

[0065] Embodiment Five

[0066] The difference between the embodiment and Embodiment One is that the embodiment uses a sealing piece to replace the limiting cavity 228, the first matching part 125 is abutted against the sealing piece, and the second matching surface 124 is respectively abutted against the first fixed part 229 and the second fixed part 2211, so that the connection of the milk storage container 1 and the connecting piece 2 is realized.

[0067] The above is only used to further illustrate the technical content of the utility model by means of embodiments, so that the reader can more easily understand, but does not represent that the implementation mode of the utility model is limited to this, and any technical extension or re-creation made according to the utility model is protected by the utility model. The protection scope of the utility model is subject to the claims.
