[0031] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0033] like Figures 1 to 7 As shown, the negative pressure type nipple depression correction device comprises a negative pressure tube 1, a bra 2 is arranged at the end of the negative pressure tube 1, a grip 3 is fixedly connected to the bottom end of the negative pressure tube 1, an adjustment component 4 is arranged inside the grip 3, a locking component 5 is arranged on the side of the grip 3, a docking component 6 is arranged at the connection between the negative pressure tube 1 and the bra 2, the locking component 5 cooperates with the adjustment component 4 to lock the adjustment component 4, and the docking component 6 is used to connect the negative pressure tube 1 and the bra 2;

[0034] When in use, fit the bra 2 on the chest to ensure that the nipple is located in the middle of the bra 2, and use the adjustment component 4 to achieve the negative pressure state of the negative pressure tube 1. It is driven by the vertical force to effectively avoid the compression or pressure relief caused by the horizontal force, thereby improving the stability of the device during operation. Use the locking component 5 to lock the adjustment component 4 to ensure the continuation of the negative pressure state and improve the correction efficiency. The docking component 6 can facilitate the disassembly and assembly of the bra 2 and the negative pressure tube 1.

[0035] like Figure 2 and Figure 3 As shown, the adjustment component 4 includes a push rod 401 movably inserted in the bottom end of the grip rod 3, a slider 403 is fixedly connected to the top of the push rod 401, an inclined rod 404 is hinged on the side of the slider 403, a plug rod 406 is movably inserted in the end of the negative pressure tube 1 away from the bra 2, and the end of the inclined rod 404 away from the slider 403 is hinged on the lower surface of the plug rod 406, a cavity 405 is provided in the middle of the negative pressure tube 1, a piston 407 is slidably connected inside the cavity 405, and the piston 407 is fixedly connected to one end of the plug rod 406 extending into the cavity 405, a slide groove 402 is provided in the middle of the grip rod 3, and the slider 403 slides inside the slide groove 402;

[0036] Push the push rod 401 upward, and the push rod 401 will drive the slider 403 to slide inside the slide groove 402. The upward movement of the slider 403 will drive the inclined rod 404 to move. The upward movement of the inclined rod 404 will inevitably cause the other end to flip outward, and then pull the plug rod 406 to move. The plug rod 406 pulls the piston 407 to slide in the cavity 405, so that the pressure in the cavity 405 is reduced, and the pressure in the bra 2 is also reduced, reaching a negative pressure state to correct the nipple retraction. Since the user applies the thrust from the bottom to the top, it can effectively avoid the compression or pressure relief caused by the horizontal force, thereby improving the stability of the device during operation.

[0037] like Figures 2 to 4 As shown, the locking assembly 5 includes a shaft rod 501 rotatably connected to the inner wall of the slide groove 402, a hook 502 is fixedly connected to the lower surface of the shaft rod 501, a hook groove 503 is opened on the upper surface of the slider 403, the cross section of the hook groove 503 is convex, the hook 502 is movably clamped in the inside of the hook groove 503, a rotating rod 505 is movably inserted into the outer surface of the grip 3, and one end of the rotating rod 505 extending into the slide groove 402 is fixedly connected to a driving wheel 506, a driven wheel 507 is fixedly sleeved on the outer surface of the shaft rod 501, the driving wheel 506 is meshed and connected with the driven wheel 507, and a rotating disk 508 is fixedly connected to one end of the rotating rod 505 extending out of the slide groove 402, and a torsion spring 504 is movably sleeved on the outer surface of the shaft rod 501, one end of the torsion spring 504 is fixedly connected to the outer surface of the shaft rod 501, and the other end of the torsion spring 504 is fixedly connected to the inner wall of the slide groove 402;

[0038] When the slider 403 slides to the upper part of the slide groove 402, it will contact the hook 502. Since the bottom of the hook 502 is an inclined surface, it will push the hook 502 to drive the shaft rod 501 to deflect and squeeze the torsion spring 504. The slider 403 continues to move upward, causing the hook 502 to be stuck in the hook groove 503. At this time, the torsion spring 504 rebounds and drives the hook 502 to restore to a vertical state. The hook 502 is stuck in the hook groove 503, thereby locking the slider 403 and then locking the plug rod 406, ensuring that the negative pressure tube 1 is in a continuous negative pressure state, improving the correction efficiency, and at the same time, there is no need for the user to apply thrust all the time.

[0039] like Figures 5 to 7 As shown, the docking assembly 6 includes a docking hole 602 opened at the end of the negative pressure tube 1, a docking rod 603 is fixedly connected to the end of the bra 2, and the docking rod 603 is movably engaged with the inside of the docking hole 602, the end of the negative pressure tube 1 is rotatably connected to the gear ring 601, the inner wall of the negative pressure tube 1 is rotatably connected to the center rod 605, the end of the center rod 605 is fixedly connected to the inner gear 606, the inner gear 606 is meshedly connected to the inside of the gear ring 601, an eccentric wheel 607 is fixedly sleeved on the middle part of the outer surface of the center rod 605, and a side groove 604 is opened on the outer surface of the docking rod 603, and the eccentric wheel 607 is slidably engaged with the inside of the side groove 604;

[0040] Rotating the gear ring 601 will drive the internal gear 606 to rotate, and then drive the eccentric wheel 607 to rotate through the center rod 605, so that the eccentric wheel 607 slides out of the side groove 604 on the outer surface of the docking rod 603, and the docking rod 603 loses its limit. Pulling the bra 2 outward can make the docking rod 603 slide out of the docking hole 602, so as to achieve the effect of disassembling the bra 2, which is convenient for cleaning and disinfecting the bra 2.

[0041] The technical solution provided by the present invention is that when in use, the user holds the grip rod 3, first pushes the plug rod 406 to the front end, then fits the bra 2 onto the chest to ensure that the nipple is located in the middle of the bra 2, and then pushes the push rod 401 upward, the push rod 401 will drive the slider 403 to slide inside the slide groove 402, and the slider 403 will drive the inclined rod 404 to move while moving upward, and the inclined rod 404 will inevitably cause the other end to flip outward, and then pull the plug rod 406 to move, and the plug rod 406 pulls the piston 407 to slide in the cavity 405, so that the pressure in the cavity 405 is reduced, and the pressure in the bra 2 is also reduced, so as to reach a negative pressure state to correct the situation of nipple depression. Since the user applies thrust from the bottom to the top, it can effectively avoid the situation of compression or pressure relief caused by applying force in the horizontal direction, thereby improving the stability of the device during operation. The upper part of the groove 402 will contact the hook 502. Since the bottom of the hook 502 is an inclined surface, the hook 502 will be pushed to drive the shaft rod 501 to deflect and squeeze the torsion spring 504. The slider 403 continues to move upward, which will cause the hook 502 to be stuck in the hook groove 503. At this time, the torsion spring 504 rebounds and drives the hook 502 to restore the vertical state. The hook 502 is stuck in the hook groove 503 to achieve the purpose of locking the slider 403, and then the plug rod 406 is locked, ensuring that the negative pressure tube 1 is in a continuous negative pressure state, improving the correction efficiency, and at the same time, there is no need for the user to apply thrust all the time. When the pressure is released, the turntable 508 is pushed upward to drive the rotating rod 505 to rotate, and then the driven wheels 507 on both sides are driven to rotate synchronously through the active wheel 506, so that the shaft rod 501 drives the hook 502 to deflect and release the lock on the slider 403, and the slider 403 moves downward to achieve the effect of pressure relief;

[0042] After use, the gear ring 601 is rotated. During the rotation of the gear ring 601, the internal gear 606 is driven to rotate, and then the eccentric wheel 607 is driven to rotate through the center rod 605, so that the eccentric wheel 607 slides out of the side groove 604 on the outer surface of the docking rod 603, and the docking rod 603 loses its limit. The bra 2 is pulled outward to make the docking rod 603 slide out of the docking hole 602, so as to achieve the effect of disassembling the bra 2, which is convenient for cleaning and disinfecting the bra 2. When installing, the docking rod 603 is aligned with the docking hole 602 and pushed into it, and then the gear ring 601 is rotated in the opposite direction to drive the eccentric wheel 607 to be clamped in the side groove 604 to lock the docking rod 603. The structure is simple, and the disassembly and assembly of the bra 2 and the negative pressure tube 1 are convenient.
