The position of each extrusion block 61610 can be adjusted independently. After adjusting the position of each extrusion block 61610, release the first pressing block 6166. Block 6166, the first locking rod 6164 automatically pops open and is stuck in the corresponding first card slot 6168, so as to achieve the locking effect. After the zipper 603 is closed, the button 625 is pressed to start the electric heating cover 604 and the motor 609. The electric heating cover 604 heats the breast. The gear 610 rotates to drive the rotating drum 611 to rotate, the squeezing ring 614 rotates, and the roller 619 rolls on the squeezing ring 614. The roller 619 and the first piston 620 move up and down under the squeezing of the squeezing ring 614 and the support of the second compression spring 618. The plug 6222, the connecting frame 6223 and the third piston 6224 move up and down and back and forth, and the opening and closing member 6225 opens and closes repeatedly, thereby repeatedly sucking milk into the milk suction pipe 601, and the milk flows into the milk storage tank 1 along the branch pipe 5, the joint 4 and the first connecting pipe 3. The two automatic milk suction and massage heating mechanisms 6 can be used separately or simultaneously. The rotation of the rotating drum 611 drives the bracket 615 to rotate, and the massage block 607 and the movable rod 608 move back and forth under the squeezing of the squeezing block 61610 and the pulling of the tension spring 606, thereby achieving the effect of massaging the breast.

[0056] In summary, the breast pump with massage and heating function achieves the purposes of massage heating, massage intensity adjustment and distance adjustment, and meets people's usage needs.
