It should be understood that the terms used in this manner are interchangeable where appropriate, so that the embodiments of this application can be implemented in an order other than that illustrated or described herein, and that the objects distinguished by "first," "second," and the like are generally of the same type, and do not limit the number of objects; for example, the first object can be one or more. In addition, the term "and / or" in the specification and claims refers to at least one of the connected objects, and the character " / " generally indicates that the objects connected are in an "or" relationship.

[0070] The server provided in the embodiment of the present application is described in detail below through specific embodiments and application scenarios in conjunction with the accompanying drawings.

[0071] Example 1:

[0072] like Figure 1 、 Figure 2 and Figure 5As shown, the embodiment of the present application provides a breast pump device, including a container 101, a pumping shell 102, a connecting port 103, a discharge port 104 and a cover 105, and further including a pumping device installed in the pumping shell 102 for generating negative pressure in the pumping shell 102; a pair of anti-return devices 2, respectively installed in the connecting port 103 and the discharge port 104, so that the milk can only flow in a single direction along the cover 105 → the connecting port 103 → the inner cavity of the pumping shell 102 → the discharge port 104 → the container 101.

[0073] Furthermore, the anti-return device 2 includes a shell 201, which is installed in the connecting port 103 / discharge port 104 through a thread; a plurality of drainage ports 202 are spaced apart at one end of the shell 201 to form a circular ring shape; a liquid inlet 203 is arranged at the other end of the shell 201; a anti-return slide 204, which can be slidably inserted into the end of the shell 201 with the drainage port 202; a anti-return baffle 205, which is fixedly installed on the end of the anti-return slide 204 away from the drainage port 202 and is used to block the liquid inlet 203; a anti-return spring 206, which is sleeved on the outside of the anti-return slide 204, one end of which abuts against the anti-return baffle 205, and the other end abuts against the end wall of the inner cavity of the shell 201 with the drainage port 202.

[0074] Furthermore, the pumping device includes a pumping piston 3, which is movably installed in the inner cavity of the pumping shell 102; a lifting connection 4, which is used to enable the pumping piston 3 to be lifted and lowered in the inner cavity of the pumping shell 102; an actuating assembly, which is used to cooperate with the lifting connection 4 to control the lifting and lowering of the pumping piston 3, the connecting port 103 is located at the bottom of the side wall of the pumping shell 102, and the discharge port 104 is located at the bottom end of the pumping shell 102.

[0075] Furthermore, the lifting connection member 4 includes a connecting frame 401, which is fixedly installed in the middle of the inner cavity of the pumping shell 102; a lifting sleeve 402, which can be lifted and inserted into the connecting frame 401, and the lower end is fixedly connected to the top surface of the pumping piston 3; a support shaft 403, which can be slidably inserted into the lifting sleeve 402, and the upper and lower ends are respectively abutted against the upper and lower ends of the inner cavity of the pumping shell 102.

[0076] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when in use, the cover body 105 is covered on the breast of the user, so that the nipple is aligned with the connecting port 103, and then the actuating assembly cooperates with the lifting connecting member 4 to drive the pumping piston 3 to intermittently rise and fall in the inner cavity of the pumping shell 102. When the pumping piston 3 rises in the inner cavity of the pumping shell 102, a negative pressure is generated in the inner cavity of the pumping shell 102, so that the non-return device 2 located in the connecting port 103 is opened, so that a negative pressure is generated in the cover body 105, and the lotion enters the inner cavity of the pumping shell 102 through the connecting port 103. At this time, the non-return device 2 located in the discharge port 104 is closed. Then, the pumping piston 3 descends in the inner cavity of the pumping shell 102, and a positive pressure is generated in the inner cavity of the pumping shell 102. At this time, the non-return device 2 in the connecting port 103 is closed, and the non-return device 2 in the discharge port 104 is opened, so that the lotion flows from the inner cavity of the pumping shell 102 through the discharge port 104 into the container 101;

[0077] When the inner cavity of the pumping shell 102 is under negative pressure / positive pressure, the non-return baffle 205 located in the connecting port 103 / discharge port 104 slides toward the corresponding discharge port 202, so that the corresponding liquid inlet 203 is opened, and the corresponding non-return spring 206 is compressed. When the inner cavity of the pumping shell 102 is under positive pressure / negative pressure, the corresponding non-return spring 206 releases elastic potential energy, so that the corresponding non-return baffle 205 moves toward the liquid inlet 203, thereby blocking the liquid inlet 203.

[0078] Example 2:

[0079] like Figures 1 to 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the actuating assembly further includes a mounting groove body 5, which is fixed to the top of the side wall of the pumping shell 102 and connected to the top of its inner cavity; a transverse slide 10, which can be laterally slidably installed in the mounting groove body 5; a transmission unit 6, which is used to make one end of the transverse slide 10 connected to the lifting sleeve 402 in a transmission manner; a manual pushing unit 7, which uses human power to drive the transverse slide 10 to move; and an electric pushing unit 8, which uses motor 801 to drive the transverse slide 10 to move.

[0080] Furthermore, the transmission unit 6 includes a transmission frame 601, whose inner cavity runs through from top to bottom; a pair of transmission bevels 602, symmetrically arranged on the front and rear side walls of the transmission frame 601; a pair of transmission sliders 603, symmetrically fixed on the outer wall of the lifting shaft sleeve 402, the middle and upper parts of the lifting shaft sleeve 402 can slide in the inner cavity of the transmission frame 601, and the pair of transmission sliders 603 can slide in the corresponding transmission bevels 602 respectively, and the lower ends of the pair of transmission bevels 602 are close to the transverse sliding slide 10, and the upper ends are away from the transverse sliding slide 10.

[0081] Also disclosed is a method for using a breast pump device, comprising the following steps:

[0082] S1. Place the cover 105 on the user's breast;

[0083] S2, start the electric push unit 8 / manually drive the manual push unit 7;

[0084] S3, the transmission unit 6 cooperates with the lifting connector 4, the pumping piston 3 rises in the inner cavity of the pumping housing 102, and negative pressure is generated in the inner cavity of the pumping housing 102;

[0085] S4, the check device 2 in the connection port 103 is opened, the check device 2 in the discharge port 104 is closed, and the emulsion enters the inner cavity of the pumping shell 102 from the cover 105;

[0086] S5: The transmission unit 6 cooperates with the lifting connector 4 to move the pumping piston 3 downward in the inner cavity of the pumping housing 102, generating a positive pressure in the inner cavity of the pumping housing 102;

[0087] S6 , the non-return device 2 in the connecting port 103 is closed, the non-return device 2 in the discharge port 104 is opened, and the emulsion in the inner cavity of the pumping shell 102 enters the container 101 .

[0088] In this embodiment of the present application, due to the adoption of the above-mentioned structure and method, the transverse sliding plate 10 can be manually controlled to slide by the manual pushing unit 7, and can also be electrically controlled to slide by the electric pushing unit 8, so that the transverse sliding plate 10 can intermittently slide left and right in the inner cavity of the mounting groove body 5. When the transverse sliding plate 10 slides into the inner cavity of the pumping shell 102, the transmission frame 601 slides in the direction away from the mounting groove body 5. At this time, each transmission slider 603 slides from the upper end to the lower end of the corresponding transmission inclined groove 602, and the lifting sleeve 402 and the pumping piston 3 move downward along the support shaft 403, so that positive pressure is generated in the inner cavity of the pumping shell 102. When the transverse sliding plate 10 slides outside the inner cavity of the pumping shell 102, the transmission frame 601 slides in the direction of the mounting groove body 5, and each transmission slider 603 slides from the lower end to the upper end of the corresponding transmission inclined groove 602, and the lifting sleeve 402 and the pumping piston 3 move upward along the support shaft 403, so that negative pressure is generated in the inner cavity of the pumping shell 102.

[0089] Example 3:

[0090] like Figures 1 to 2 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the manual pushing unit 7 further includes a pair of notches 701, which are symmetrically arranged on the front and rear side walls of the mounting groove body 5; a pair of pushing rods 702, which are symmetrically fixed on the front and rear side walls of the transverse sliding slide 10 away from the transmission unit 6, and extend out of the mounting groove body 5 through the corresponding notches 701; a shifting frame 703, which includes a pair of swing arms 7032, the upper ends of which are hinged to the front and rear side walls of the mounting groove body 5 through hinge shafts, and the lower ends of which are fixed to each other through a transverse plate 7031.

[0091] Furthermore, the manual pushing unit 7 also includes a pair of reset rods 704, which are respectively arranged on the front and rear side walls of the mounting groove body 5; a pair of reset springs 705 are respectively mounted on each reset rod 704, and the end away from the pumping shell 102 abuts against the outer wall of the corresponding swing arm 7032, and both ends of each reset rod 704 are fixed to the outer wall of the mounting groove body 5 through a fixing block 706, and the middle part of each swing arm 7032 passes between the corresponding reset rod 704 and the outer wall of the mounting groove body 5.

[0092] Furthermore, it also includes a ballast spring 707 , which is arranged between the bottom surface of the pumping piston 3 and the bottom of the inner cavity of the pumping shell 102 and is sleeved on the outside of the support shaft 403 .

[0093] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when driven manually, the bottom end of the shifting frame 703 is pressed toward the pumping shell 102, and each swing arm 7032 swings around the corresponding hinge axis toward the pumping shell 102. Each swing arm 7032 cooperates with the outer wall of the corresponding push rod 702 to push the transverse slide 10 to slide into the inner cavity of the pumping shell 102, and the pumping piston 3 descends, causing negative pressure to be generated in the inner cavity of the pumping shell 102. At the same time, the ballast spring 707 is compressed and shortened, and each return spring 705 is compressed and shortened. Then the shifting frame 703 is released, and each ballast spring 707 and each return spring 705 release their elastic potential energy, respectively pushing the pumping piston 3 up and pushing each swing arm 7032 to reset. At this time, each swing arm 7032 is out of contact with each push rod 702.

[0094] Example 4:

[0095] like Figures 1 to 4 As shown, in this embodiment, in addition to the structural features of the aforementioned embodiments, the electric sliding unit 8 includes a groove 802, which is arranged at the bottom of the mounting groove body 5; a gear column 803, which is driven by the motor 801 and can be rotatably installed in the groove 802; and a transmission rack 804, which is fixedly installed on the bottom surface of the transverse slide 10 and cooperates with the gear column 803 in transmission.

[0096] Furthermore, the transverse sliding plate 10 includes a fixed section 1001, which is connected to the transmission unit 6 and has a transverse slot 1002 in the middle; a movable section 1003, which is sleeved on the outside of the fixed section 1001 through a connecting slot 1004; a sliding block 1005, which can be transversely slidably installed in the transverse slot 1002 and is rotatably connected to the inner wall of the connecting slot 1004 through a hinge shaft; a preload spring 1006, which is arranged between the end of the transverse slot 1002 away from the pumping shell 102 and the sliding block 1005; and a plurality of snap-fit ​​fittings 9, which are used to adjust the overlapping range of the connecting slot 1004 and the fixed section 1001.

[0097] Furthermore, the snap-fitting member 9 includes a pair of grooves 901, which are symmetrically arranged at the bottom of the front and rear side walls of the connecting groove 1004; two groups of clamping blocks 902, which are symmetrically arranged on the front and rear side walls of the fixed section 1001, and each clamping block 902 is in a 7 shape and is spaced apart from each other; a pair of plug-in blocks 903, which are symmetrically arranged in each groove 901, for plugging and mating with each clamping block 902.

[0098] Furthermore, it also includes a pull rod 904 which is fixedly installed on the top of the moving section 1003 .

[0099] In this embodiment of the present application, due to the adoption of the above-mentioned structure, when driven by electric means, the motor 801 first drives the gear column 803 to rotate clockwise, and cooperates with the transmission rack 804 to drive the transverse slide 10 to slide into the inner cavity of the pumping shell 102, so that the pumping piston 3 descends, and positive pressure is generated in the inner cavity of the pumping shell 102. The ballast spring 707 is compressed and shortened, storing elastic potential energy. When the transmission rack 804 moves to a point where it is out of the transmission range with the gear column 803, the motor 801 is powered off, and the ballast spring 707 is released. The elastic potential energy is released, and the pumping piston 3, the lifting sleeve 402, the transmission frame 601, the pair of transmission slide blocks 603 and the pair of transmission chute 602 are coordinated to make the transverse slide plate 10 and the transmission rack 804 slide out of the inner cavity of the pumping housing 102. Since the motor 801 is in the power-off state at this time, the moving transmission rack 804 can drive the gear column 803 to rotate. At this time, negative pressure is generated in the inner cavity of the pumping housing 102. In the above process, there is no cooperation between each push rod 702 and the corresponding swing arm 7032.

[0100] When it is necessary to adjust the lifting stroke of the pumping piston 3, the moving section 1003 is pulled away from the fixed section 1001 by the pull rod 904, so that each plug 903 is disengaged from the corresponding block 902, and the sliding block 1005 slides in the moving section 1003 and squeezes the preload spring 1006. Then, the pull rod 904 is pulled upward to lift the moving section 1003 away from the corresponding hinge shaft end. At this time, each plug 903 is disengaged from the corresponding block 902. Then, the pull rod 904 is pulled or pushed to adjust the position of each plug 903 along with the moving section 1003. After the connecting groove 1004 and the fixed section 1001 are adjusted to a suitable overlapping range, the pull rod 904 is lowered and the corresponding moving section 1003 is away from one end of the corresponding hinge shaft. At this time, each plug 903 drops to the relative position of the corresponding block 902 at this time, and each block 902 enters the corresponding groove 901. After that, release the pull rod 904, and the load spring 707 releases elastic potential energy, driving the sliding block 1005 and the moving section 1003 to slide toward the pumping shell 102, so that the plug block 903 and the corresponding card block 902 are engaged and locked with each other, so that the length of the transverse slide 10 is adjusted, and the transmission rack 804 at the bottom of the transverse slide 10 can increase / decrease the length of the transmission engaged with the gear column 803, and the distance between each push rod 702 and the transmission frame 601 increases / decreases, while the intermittent operation time and interval of the motor 801 remain unchanged, and the swing stroke of each swing arm 7032 remains unchanged (between a pair of fixed blocks 706), so that the stroke of the transverse slide 10 can be changed as the length of the transverse slide 10 increases / decreases, so that the stroke of each transmission slider 603 in the corresponding transmission chute 602 increases / decreases, and finally the lifting stroke of the pumping piston 3 increases / decreases.

[0101] Correspondingly, the rack 804 is also divided into a pair of outer racks 8041 located at the bottom surface of the movable section 1003 and an inner rack 8042 located at the bottom of the fixed section 1001. As the position between the movable section 1003 and the fixed section 1001 is adjusted, the position between each outer rack 8041 and the inner rack 8042 also changes, but there is always an overlapping area to ensure that the gear column 803 can engage with the rack 804 as a whole for transmission.
