[0037] Example 1:

[0038] like Figures 3 to 8 A portable nipple corrector is shown, comprising a main body housing 100 and an air extraction device 2 installed inside the main body housing 100. More specifically, the main body housing 100 is a protective shell for mounting the air extraction device 2 and for conforming to the surface of the user's breast skin. The main body housing 100 may be made of a non-conductive material that has the structural strength to protect the internal components, so as to avoid leakage current from the internal electronic components that could affect the user's skin. The main body housing 100 has an adsorption surface 11 for adsorbing the skin on the side close to the user's skin. The adsorption surface 11 is arc-shaped and concave inward.

The cavity wall of the adsorption cavity 12 has a vent hole 121 that communicates with the inside of the main body housing 100.

[0039] More specifically, the air extraction device 2 is a suction pump assembly used by the nipple corrector to extract air from the suction chamber 12 so that the suction surface 11 of the main unit housing 100 can be stably attached to the user's skin. The air extraction device 2 includes an air pump component for air extraction and a power supply 7 for providing power for continuous operation.

[0040] More specifically, in use, the user adheres the suction surface 11 of the main shell 100 to the surface of their own breast, so that the skin area at the nipple position extends into the suction cavity 12 to form a closed suction space (i.e. a closed space), the user indirectly triggers the switch of the air pump by pressing the soft button 8 on the main shell 100, starts the air suction device 2 to operate and starts to suck the air in the suction cavity 12 through the air hole 121, so that the suction cavity 12 forms a negative pressure state, in which the concave or indented nipple is sucked out of the skin surface and changes from a concave shape to a convex shape, thereby achieving the effect of correcting the nipple indentation, making the nipple gradually more prominent, and using the nipple corrector according to a certain frequency and time can gradually help the nipple to recover to a normal shape, facilitating breastfeeding.

[0041] More specifically, since the air suction device 2 is installed inside the main shell 100, the air suction device 2 no longer occupies space outside the main shell 100, the overall volume is small, and the user can carry and store it outdoors or outdoors, and it can be directly powered on without assembly when in use, which is convenient and fast, and the user can also stand and walk with both hands free in the suction state, facilitating user movement.

[0047] During production, the vacuum device 22 is first installed in the inner housing 102, and the soft button 8 is installed in the button positioning hole 1011 on the outer housing 101. Then, the outer housing 101 and the inner housing 102 are closed to form the inner cavity 13, which is then ready for use. During disassembly and maintenance, the inner housing 102 is separated from the outer housing 101 to enter the interior for maintenance or replacement of electronic components.

[0048] Example 3:

[0049] Based on Example 2, such as Figures 3 to 7 The portable nipple corrector shown has an inner housing 102 equipped with a control module 1021 for controlling the operation of the device.

The control module 1021 includes a level button 1022 for adjusting the suction level and a circuit board for mounting the level button 1022. The air pump is electrically connected to the circuit board, so the level button 1022 can be used to start, stop, or adjust the suction level.

[0050] More specifically, the soft button 8 is located on the outer casing 101 near the gear button 1022. The soft button 8 extends towards the gear button 1022 with a key extension 81 for contacting the gear button 1022. When the user presses the soft button 8, it touches the gear button 1022 via the key extension 81, which can start or stop the air pump and adjust the suction strength of the air pump. The user can control the suction strength of the suction device 2 through the gear button 1022 and can adjust the suction level to suit their own needs, making the user more comfortable during use.

[0051] Based on Example 3, as another example, such as Figures 3 to 5 as well as Figure 7As shown, the circuit board of the control module 1021 is provided with a state indicating lamp 9, and a shell lamp hole 1012 is formed on the outer shell 101 close to the state indicating lamp 9.

Also, the circuit board can be externally connected through this connector structure to facilitate the user to perform data programming, data collection and recovery, data viewing and other operations on the circuit board.

[0054] Embodiment 4:

[0055] On the basis of embodiment 3, as shown in Figure 5 and Figure 7 A portable nipple corrector, as shown in the drawings, the suction device 2 comprises an exhaust valve 21 and a pressure sensor 22, the pressure sensor 22 is electrically connected with the control module 1021, the exhaust valve 21 is used for adjusting the real-time air pressure of the air pump piece, so that it can be stabilized in the safe and controllable air pressure interval, the pressure sensor 22 is a sensor for the control module 1021 to detect the real-time air pressure, the pressure sensor 22 collects the air pressure data and returns to the control module 1021 for processing, so that the control module 1021 can real-time control the air pressure value in the suction cavity 12.

[0056] On the basis of embodiment 4, as another embodiment, as shown in Figure 3 , Figure 4 and Figure 7As shown, the air extraction device 2 can be connected to the exhaust valve 21 and the air vent 121 through the air pipe 23, so that the overall installation layout is more reasonable, the reserved distance between components is increased, the pressure sensor 22 is connected to the air vent 121 through the air pipe 23 alone, the aggregation and crowding of electronic components are avoided, the installation difficulty is reduced, and the production efficiency is improved.

[0057] Embodiment 5:

[0058] On the basis of Embodiment 1 or Embodiment 2, a portable nipple corrector as shown in Figures 3 to 8 The suction cavity 12 has an air vent recess 122 for avoiding the user's nipple and an air vent groove 123 for avoiding the user's breast skin. The air vent recess 122 is located on the side of the suction cavity 12 away from the suction surface 11, i.e. at the end of the suction cavity 12 close to the inner cavity 13 of the shell, which is the innermost position of the suction cavity 12 with the maximum depth. The air vent groove 123 extends from the air vent recess 122 to the air vent hole 121. The air vent recess 122 and the air vent groove 123 are both recessed towards the direction away from the center of the suction cavity 12. The air vent hole 121 is located in the air vent groove 123. Even if the user's breast skin fills the suction cavity 12, air can still flow from the air vent groove 123 through the air vent hole 121 to form a negative pressure state for suction, avoiding the blockage of the air vent hole 121 when the skin is attached, ensuring smooth air flow through the air vent hole 121, and facilitating user use.

[0059] On this basis, the number of air vent holes 121 and air vent grooves 123 is one-to-one correspondence, which can be single, two, or more than two arranged in a circumferential interval around the central axis of the suction cavity 12.

[0060] Embodiment 6:

[0061] On the basis of Embodiment 3, a portable nipple corrector as shown in Figures 5 to 9The portable nipple corrector shown also includes a hot compress module 5, which is a heating assembly of the nipple corrector for heating the adsorption surface 11. The hot compress module 5 uses a heat-conducting heating film 51 to cover the inner side of the main housing 100 and is located close to the adsorption surface 11. More specifically, the heating film 51 covers the side of the inner housing 102 away from the adsorption surface 11. The heating film 51 is electrically connected to the control module 1021. The user can start the control module 1021 to conduct electricity between the heating film 51 and the power supply 7 by pressing the soft key 8 to trigger the gear button 1022 on the circuit board via the key extension 81. After the heating film 51 is powered on, it starts to heat and transfers heat to the adsorption surface 11 through the inner housing 102, so that the user's skin can absorb heat from the adsorption surface 11 and warm up, achieving a hot compress effect. Hot compress can dilate local blood vessels and increase blood flow, thereby improving blood circulation and helping to relieve swelling and pain caused by insufficient blood flow or local blood stasis. Hot compress can also relax muscles and relieve muscle soreness and discomfort around the breast, making it convenient for users to use.

[0062] On this basis, the heating film 51 is provided with hot compress avoiding holes 511 for avoiding obstacles such as columns, holes, devices, etc. The area of the hot compress avoiding holes 511 is larger than the area occupied by the obstacles by 1 to 5 mm2 of reserved space, so that the heating film 51 can be smoothly covered on the side of the inner housing 102 away from the adsorption surface 11 to facilitate production, installation and ensure the largest possible heating area.

[0063] On this basis, the heating film 51 is provided with heating wires 512 as heating elements, which can immediately provide heating and warming after being powered on, with a fast temperature rise response. The heating wires 512 are spaced apart and wound from the outside to the inside of the center of the heating film 51, which can as evenly as possible balance the warming effect of the heating film 51 and avoid local uneven warming.

[0064] On this basis, the hot compress effect can also achieve the effect of driving away cold. When the user uses the nipple corrector with clothes open, it is easy to catch a cold due to the influence of the external environment. The hot compress effect of the heating film 51 can provide a certain temperature of the warm-keeping function and achieve a certain effect of driving away cold.

[0065] On the basis of Embodiment 6, as another embodiment, the hot compress module 5 also includes a temperature control element for controlling the heating temperature. The temperature control element can use an NTC thermistor to collect and adjust the actual heating temperature of the heating film 51, or can transmit the collected temperature back to the control module 1021 for processing to control the heating temperature of the hot compress module 5, so as to avoid the heating temperature of the heating film 51 being too high to cause burns to the user's skin, and to help the hot compress module 5 to be safe and controllable in heating temperature, making it convenient for the user to use.

[0066] Embodiment 7:

[0067] On the basis of Embodiment 3, as shown in Figures 5 to 9 The portable nipple corrector shown in Embodiment 3 further comprises a cold compress module 6, which is a refrigeration component of the nipple corrector for reducing the temperature of the adsorption surface 11. The cold compress module 6 can be installed on the inner side of the main housing 100 and located close to the adsorption surface 11 by using a refrigeration semiconductor component 61. More specifically, the refrigeration semiconductor component 61 is covered on the side of the inner housing 102 away from the adsorption surface 11. The refrigeration semiconductor component 61 is electrically connected to the control module 1021. The user can start the control module 1021 to conduct the circuit between the refrigeration semiconductor component 61 and the power supply 7 by pressing the soft key component 8 to trigger the gear button 1022 on the circuit board through the key position extension 81. After being powered on, the refrigeration end of the refrigeration semiconductor component 61 starts to cool and reduce the temperature. The refrigeration end of the refrigeration semiconductor component 61 absorbs heat from the inner housing 102 and transfers it to the heat dissipation end of the refrigeration semiconductor component 61, so that the user's skin can be affected by the low temperature of the adsorption surface 11 to reduce the surface temperature of the skin, achieving the cold compress effect. Cold compress can make local blood vessels contract and reduce blood flow, helping to reduce inflammation and swelling in the breast area, thereby relieving pain and facilitating user use.

[0068] Embodiment 8:

[0069] On the basis of Embodiment 1 or Embodiment 2, as shown in Figures 2 to 6 The portable nipple corrector shown in Embodiment 3 further comprises a flexible suction cup 3 for easy skin fitting. The flexible suction cup 3 adopts a thin film suction cup structure. More specifically, the flexible suction cup 3 has a fitting part 31 for skin fitting and a channel part 32 for installation and extension into the adsorption cavity 12. The fitting part 31 is trumpet-shaped and opens outward to form a curved film. The channel part 32 is cylindrical and extends outward to form a straight cylinder structure. The channel part 32 has a hollow airflow channel 321 that is connected to the air suction device 2 through the air vent hole 121 for the flow of gas during suction. The flexible suction cup 3 is installed in the adsorption cavity 12 through the channel part 32, and the fitting part 31 is also fitted on the adsorption surface 11, replacing the adsorption surface 11 to fit the user's skin. Since the flexible suction cup 3 is made of soft material, the local thickness can effectively increase the contact area with the user's skin, and the negative pressure state is more stable when forming a closed space. The elastic reset effect of the silicone material is good, and it can be installed in the adsorption cavity 12 to reduce the possibility of loosening and falling off or fitting deviation. Through the elastic pressure of the material itself on the cavity wall of the adsorption cavity 12, it will not easily loosen and fall off, facilitating user use.

[0070] The flexible suction cup 3 can be detachably installed in the adsorption cavity 12, which can facilitate the user to detach and clean and disinfect, avoid bacteria accumulation on the flexible suction cup 3, and improve the cleanliness and hygiene of the skin contact.

More specifically, as shown... Figure 4 As shown, a hollow, through-hole clamping structure 322 is provided on the side of the channel portion 32 away from the fitting portion 31. The clamping structure 322 has a first clamping flap 3221 on the side away from the fitting portion 31, and a second clamping flap 3222 is provided at intervals on the first clamping flap 3221 facing the inner side of the channel portion 32. The waterproof and breathable component 4 is installed in the space between the first clamping flap 3221 and the second clamping flap 3222. The first clamping flap 3221 and the second clamping flap 3222 elastically clamp the waterproof and breathable component 4 to restrict its position and prevent it from easily falling off. When air is drawn in, the gas flows through the waterproof and breathable membrane 41 in the middle of the waterproof and breathable component 4 and enters the vent 121. When milk is accidentally drawn out, the waterproof and breathable membrane 41 blocks the milk from flowing into the adsorption chamber 12, which has the function of preventing liquid flow and achieving the effect of avoiding leakage.

[0074] Example 10:

[0075] On the basis of embodiment 9, the waterproof and breathable member 4 can be made of one of the following fiber structures: polyphenylene sulfide woven fabric or polytetrafluoroethylene fiber. In this embodiment, the waterproof and breathable member 4 is made of polytetrafluoroethylene fiber as the main material. The polytetrafluoroethylene fiber can be made of polytetrafluoroethylene (PTFE) or expanded polytetrafluoroethylene (ePTFE) as the main fiber component. The polytetrafluoroethylene fiber has excellent waterproof performance. The high-density molecular structure can effectively prevent water from penetrating, ensuring that the waterproof and breathable member 4 has good waterproof effect. The microporous structure of the polytetrafluoroethylene fiber has excellent air permeability, allowing water vapor or other air to pass through, thereby achieving air permeability. In addition, the polytetrafluoroethylene fiber has strong resistance to most chemicals and solvents and can maintain stable performance in various chemical environments. It is suitable for contact with different types of liquids without chemical reaction, avoiding contamination of the adsorption cavity 12. The polytetrafluoroethylene fiber also has good high-temperature resistance and can be used in high-temperature environments without losing its performance. It is suitable for use in high-temperature environments and has strong temperature change adaptability. The surface tension of the polytetrafluoroethylene fiber is low, making it difficult for dirt, oil and other substances to adhere to its surface, which helps to maintain the cleanliness and air permeability of the waterproof and breathable member 4.

[0076] As shown in Figures 1 to 9 One of the embodiments of the utility model on the basis of the above-mentioned embodiments:

[0077] In use, the user adheres the adsorption surface 11 of the inner shell 102 to the surface of the breast, so that the skin area at the nipple position extends into the adsorption cavity 12 to form a sealed and adhered suction space (i.e. a sealed space). The user presses the soft key member 8 on the main shell 100 to trigger the gear button 1022 via the key extension 81, so that the control module 1021 controls the start and stop of the operation of the air suction device 2, the hot compress module 5, the cold compress module 6 and other devices through the circuit board.

[0078] When suctioning, the user can start the control module 1021 by pressing the soft key member 8 to trigger the gear button 1022 on the circuit board via the key extension 81 to turn on the circuit between the air suction device 2 and the power supply 7. After starting the air suction device 2, the air pump starts to suck the air in the adsorption cavity 12 through the air hole 121, so that the adsorption cavity 12 forms a negative pressure state. In the negative pressure state, the nipple can be sucked out of the skin surface from the concave shape to the convex shape, thereby achieving the effect of correcting the nipple depression. Gradually, the nipple becomes more prominent. Using the nipple corrector at a certain frequency and time can gradually help the nipple to recover to normal shape, which is convenient for the mother to breastfeed.

[0079] When adjusting the suction level, users can intuitively know the specific suction level by the number of times the status indicator light 9 is lit. They can also intuitively know the remaining battery power of the nipple corrector by the status indicator light 9, which is convenient for users.

[0080] During hot compress, the user can activate the control module 1021 by pressing the soft button 8 via the key extension 81 to trigger the gear button 1022 on the circuit board, which connects the heating film 51 to the power supply 7. After the heating film 51 is powered on, it begins to heat up and transfers the heat through the inner shell 102 to the adsorption surface 11, allowing the user's skin to absorb heat from the adsorption surface 11 and become warm, thus achieving the effect of hot compress. Hot compress can dilate local blood vessels, increase blood flow, thereby improving blood circulation and helping to relieve swelling and pain caused by insufficient blood flow or local blood stagnation. Hot compress can also relax muscles and relieve soreness and discomfort in the muscles around the breast, making it convenient for users to use.

[0081] During cold compress, the user can activate the control module 1021 by pressing the soft button 8 via the key extension 81 to trigger the gear button 1022 on the circuit board, thus connecting the circuit between the cooling semiconductor 61 and the power supply 7. After power is applied, the cooling end of the cooling semiconductor 61 begins to cool down. The cooling end of the cooling semiconductor 61 absorbs heat from the inner shell 102 and transfers it to the heat dissipation end of the cooling semiconductor 61, allowing the user's skin to be affected by the low temperature of the adsorption surface 11, thereby reducing the surface temperature of the skin and achieving the cold compress effect. The cold compress can cause local blood vessels to constrict, reduce blood flow, help reduce inflammation and swelling in the breast area, thereby relieving pain and making it convenient for users to use.

[0082] like Figures 1 to 9 As shown, based on the above embodiments, the second embodiment of this utility model is as follows:

[0083] Based on the first embodiment, the nipple corrector is equipped with a flexible suction cup 3. The flexible suction cup 3 is installed in the suction cavity 12 through the channel portion 32, and the fitting portion 31 is also attached to the suction surface 11, replacing the suction surface 11 to fit the user's skin. Since the flexible suction cup 3 is made of soft material, the local thinner areas can effectively increase the contact area with the user's skin, and the negative pressure state when forming a closed space is more stable. In addition, the elasticity and restoring effect of the silicone material is good. After being installed in the suction cavity 12, the reinforcing ribs 323 can strengthen the top contact pressure, which can reduce the possibility of loosening or falling off or misalignment. The elasticity of the material itself presses against the cavity wall of the suction cavity 12, so it will not easily loosen or fall off, making it convenient for users to use.

[0084] During suction, the gas passes through the waterproof and breathable membrane 41 in the middle of the waterproof and breathable component 4 and enters the vent 121. When milk is accidentally sucked out, the waterproof and breathable membrane 41 blocks the milk from flowing into the adsorption chamber 12, which has the function of preventing liquid flow and achieving the effect of avoiding leakage.

[0085] The flexible suction cup 3 is detachably installed on the adsorption cavity 12, the characteristic can facilitate the user to detach and clean and disinfect, avoids the bacteria accumulation on the flexible suction cup 3, improves the clean and sanitary degree of contact skin.

[0086] The above is only to further illustrate the technical content of the present application by way of examples, so that the reader can more easily understand, but not represent the embodiment of the present application is limited to this, any technical extension or re-creation made according to the present application, are protected by the present application.
