[0002] A breast pump is a tool used to squeeze out breast milk accumulated in the mammary gland. Breast pumps on the market use a relatively high-frequency, low-suction air pump to stimulate breast milk secretion through high-frequency and gentle suction, and vibrate the bell mouth to massage the breasts, stimulate mammary gland secretion, and improve the effect of milk suction; however, the vibration of the bell mouth usually requires an independent vibration mechanism to drive it, so existing breast pumps with vibration function usually require two independent driving mechanisms to drive them.

[0015] The technical solutions in the embodiments of the present invention are described below in conjunction with the drawings in the embodiments of the present invention. It is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the protection scope of the present invention.

[0016] Embodiment 1: In the prior art, in order to realize simultaneous massage of the mother's breasts while the mother is sucking milk, two independent driving devices are required to drive the vibration module and the milk suction module respectively, and an independent vibration structure is required to be specially provided so that the mother's breasts can feel the vibration, which will result in a complex structure of the breast pump with a vibration function and high production cost. The micro-vibration massage breast pump provided in Embodiment 1 of the utility model is as follows: Figures 1 to 4 As shown, it includes a breast pump host, the breast pump host includes a vibration airflow generating device 1, and also includes a breast shield 2; the vibration airflow generating device 1 includes an airflow output port 11; the airflow output port 11 is tightly connected to the negative pressure end of the breast shield 2 through a pipe 3; the vibration airflow generating device 1 includes a driving device 12, an elastic membrane 13 and a sealing cover 14; the driving device 12 includes a telescopic rod 121 that can reciprocate along the rod axis direction; the sealing cover 14 includes an internal cavity; the internal cavity has and only has the airflow output port 11 and the negative pressure port connected to the outside; the negative pressure port is tightly covered with an elastic membrane 13; the elastic membrane 13 is fixedly connected to the rod end of the telescopic rod 121; the rod end of the telescopic rod 121 can move back and forth in the cavity space of the sealing cover 14; the elastic membrane 13 includes a first cover The first cover shape and the second cover shape are both cover body shapes; the elastic membrane 13 includes two deformation thresholds, when the elastic membrane 13 is deformed to the two deformation thresholds, the elastic membrane 13 will produce an instantaneous motion and convert into the first cover shape or the second cover shape; during the telescopic process, the telescopic rod 121 will drive the elastic membrane 13 to change its shape to two deformation thresholds; the elastic membrane 13 includes a first cover surface 131 and a second cover surface 132; the second cover surface 132 faces the internal volume of the sealing cover 14; in the first cover shape, the first cover surface 131 is the inner wall surface of the cover of the elastic membrane 13, and the second cover surface 132 is the outer wall surface of the cover of the elastic membrane; in the second cover shape, the first cover surface 131 is the outer wall surface of the cover of the elastic membrane, and the second cover surface 132 is the inner wall surface of the cover of the elastic membrane.

[0017] When the micro-vibration massage breast pump provided by the embodiment 1 of the utility model is used, the mother wears the breast shield 2 in combination with the breast (the breast shield 2 is a prior art, comprising a horn shield, a three-way connection and a negative pressure end that abuts against the mother's breast, and the specific structure is not described in detail here), and the vibration airflow generating device 1 inside the breast pump is operated by controlling the operation of the breast pump host, so that the vibration airflow generating device 1 generates a vibration airflow to suck the negative pressure end of the breast shield 2, so that the airflow part that provides suction to the breast is also in the form of vibration, so that the part of the breast shield 2 abutting against the mother's breast is vibrated due to the vibration airflow, thereby achieving a massage effect; the vibration airflow generating device 1 generates a vibration airflow by using the driving device 12 The telescopic rod 121 changes the state of the elastic membrane 13 at a uniform and slow speed (the specific telescopic method of the telescopic rod 121 belongs to the prior art and will not be described in detail here). When the elastic membrane 13 reaches the deformation threshold, the elastic membrane 13 will produce an instantaneous movement and produce an instantaneous change. The speed of this instantaneous change is very fast, and the instantaneous change of the elastic membrane 13 will cause the space in the internal cavity of the sealing cover 14 to be instantly reduced or instantly enlarged. The instantaneous change in the size of the space will instantly squeeze out the air in the cavity of the sealing cover 14 or inhale the external air into the sealing cover 14. Among them, the uniform and slow telescopic rod 121 is slower than the instantaneous deformation of the elastic membrane 13. The telescopic rod 121 pushes the elastic membrane 13 to change the change of the space in the sealing cover. The deformation speed is slower than the speed of the space change in the sealing cover 14 when the elastic membrane 13 produces an instantaneous deformation; when it is necessary to provide suction to the mother's breast, the telescopic rod 121 is retracted, and the telescopic rod 121 drives the elastic membrane 13 to deform, so that the elastic membrane 13 is separated from the first cover shape, and the elastic membrane is driven to separate from the interior of the cavity of the sealing cover 14 until the deformation threshold of the elastic membrane 13 is reached, and the first cover surface 131 instantly protrudes to become the outer wall surface of the cover body of the elastic membrane 13, and the second cover surface 132 is the inner wall surface of the cover body of the elastic membrane 13, and the elastic membrane 13 is in the second cover shape state; during the whole process, the air volume in the sealing cover 14 increases due to the protrusion of the elastic membrane 13, and this part of the air is sucked by the suction cup 2 connected to the pipeline. The negative pressure end of the breast shield 2 is provided, and the air volume at the negative pressure end of the breast shield 2 becomes smaller, so that the breast shield 2 can generate negative pressure to produce suction on the breast, and the negative pressure end of the breast shield 2 can produce rapid spatial changes during the period when the elastic membrane 13 is instantly transformed into the second shield shape. This instantaneous spatial change is in contrast to the slow spatial change driven only by the telescopic rod 121, so that the negative pressure airflow can present a sometimes fast and sometimes slow effect when the breast is sucked, and the sometimes fast and sometimes slow airflow forms a vibration effect; compared with the breast pump in the prior art that needs to be separately provided with a vibration structure, the device of this embodiment has a simple structure, does not require an additional vibration device and a driving mechanism for driving the vibration device, and therefore has a low production cost and a low probability of failure.

[0018] In order to prevent the connection between the telescopic rod 121 and the elastic membrane 13 from hindering the elastic membrane 13 from performing instantaneous deformation at the deformation threshold, in this embodiment, the driving device 12 includes a spring 122 that can be extended and retracted along the rod axis direction of the telescopic rod 121; one end of the spring 122 is fixed to the telescopic rod 121; the other end of the spring 122 is fixed to the center of the cover of the elastic membrane 13 through a connecting piece 123. The telescopic rod 121 is fixed to the elastic membrane 13 through the spring 122 and the connecting piece 123 fixed to the other end of the spring 122, so that after the elastic membrane 13 generates an instantaneous deformation, it can avoid being directly blocked by the telescopic rod 121 through the contraction of the spring 122, so that the elastic membrane 13 can smoothly complete the deformation.
