[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention are within the scope of protection of the present invention.
[0018] like Figure 1-5 As shown, according to the present invention, smart underwear is disclosed, including a pants body 1, a pants waist 3, and a mecha belt 2 arranged on the outside of the pants waist 3. The outside of the mecha belt 2 is fixedly provided with a power controller module 9, a drainage mechanism 8 and a cleaning mechanism 7. The cleaning mechanism 7 includes a detachable upper cover A701, a water storage shell 702 and a micro pump A703. The drainage mechanism 8 includes a detachable upper cover B801, a waste liquid shell 802 and a micro pump B803. The urethral opening of the pants body 1 is attached with an empty box 4, and the surface of the empty box 4 is provided with a flushing hole. Group A1101, flushing hole group B1102, the top of the empty box 4 is provided with a thin tube group 11 connected to the flushing hole group A1101 and the flushing hole group B1102, the input ends of the thin tube group 11 are connected to the output ends of the connector 10, the connector 10 is connected to the micro pump A703 through two water inlet pipes 5, the surface of the empty box 4 is connected with a urinary catheter 401, the bottom of the empty box 4 is connected to the drainage connector 12 through several drainage thin tubes 1201, and the drainage connector 12 is connected to the micro pump B803 through the drainage pipe 6.
[0019] Embodiment 1: The trouser body 1 and the waistband 3 are made of breathable antibacterial fabric (such as Lycra material containing bamboo fiber), and the mecha belt 2 is made of TPU material enhanced with high elastic additives, which can further enhance its elasticity and ensure that the belt can remain soft and fit after the components are installed to avoid oppression; the hollow box 4 is made of water-absorbing gel ring tube material, and its soft texture can reduce friction on the urethral opening and enhance tightness, thereby improving comfort; the hollow box 4 is made of silicone pad material, and a cavity is arranged inside the hollow box 4. The flushing hole group A1101 and the flushing hole group B1102 are distributed on the surface of the hollow box 4 but do not penetrate the hollow box 4. The thin tube group 11 is pre-buried in the wall thickness of the hollow box 4, and the output port of the thin tube group 11 is respectively connected to the flushing hole group A1101 and the flushing hole group B1102. The independent waste liquid storage bin provided at the bottom of the water-absorbing layer 403 is located in the inner cavity of the hollow box 4, and the independent waste liquid storage bin is connected to the drainage connector 12 using an independent drainage thin tube 1201; A thin film valve flap is provided inside the urinary catheter 401, which acts like a one-way valve. During urination, urine pushes the film valve flap to open, and it closes when there is no urine pressure, thus reducing the diversion of waste liquid. Wastewater housing 802 houses a high-precision multispectral sensor capable of detecting over ten biochemical parameters, including but not limited to urine pH, specific gravity, glucose, protein, ketone bodies, and hemoglobin concentration and white blood cell count in menstrual blood. Multispectral technology analyzes the interaction between light of different wavelengths and wastewater components to quickly and accurately acquire biochemical data.
[0020] Data collected by the sensor is transmitted in real time to the user's smartphone via a low-power Bluetooth module. Users simply install the accompanying app on their phone to view the results of various biochemical indicators at any time. The app features an intuitive data display interface, presenting test data in the form of charts, numerical values, and more, making it easy for users to understand their health status.
[0021] In addition to basic biochemical indicator monitoring, the solution also offers optional physiological data tracking. For female users, this includes tracking urination frequency, menstrual blood volume, and other data. The application records and analyzes this physiological data over time, generating trend reports to help users identify potential health issues and provide reference for doctors' diagnoses. A thermoelectric chip is installed inside the water storage housing 702, leveraging its Peltier effect to achieve rapid and precise temperature regulation. A temperature sensor monitors the water temperature in real time, providing feedback to the control system (a microcontroller connected to the power controller module 9). This dynamically adjusts the direction and magnitude of the current flowing through the thermoelectric chip to maintain a constant water temperature of 35-38°C. The thermocatalytic disinfection module, a graphene heating film with high thermal conductivity and excellent chemical stability, is also incorporated. When powered on, the graphene heating film rapidly heats up, disinfecting the water within the water storage housing and effectively killing bacteria, viruses, and other microorganisms, ensuring clean and hygienic flushing water.
[0022] In the preferred technical solution, the power controller module 9 includes a micro solid-state battery, a switch module, a Bluetooth module and a microcontroller. The micro solid-state battery is a lithium ceramic battery, which is a new energy storage solution that integrates lithium-ion technology with ceramic components. It has the advantages of high energy density, high safety, and long cycle life, providing endurance for internal electrical devices.
[0023] In the preferred technical solution, a water-absorbing layer 403 is provided on the surface of the hollow box 4, and an independent waste liquid storage tank is provided at the bottom of the water-absorbing layer 403. The independent waste liquid storage tank is connected to the drainage joint 12 through a drainage tube, which is used to guide the flushing waste liquid to be concentrated into the waste liquid shell 802.
[0024] In the preferred technical solution, both the upper cover A701 and the upper cover B801 are provided with a matching hole 706, and the top of the water storage shell 702 and the waste liquid shell 802 are integrally formed with an insertion rod 707 that is interference fit with the matching hole 706. The insertion rod 707 can cooperate with the rubber gasket to improve the tightness, thereby realizing quick disassembly and assembly of the upper cover A701 and the water storage shell 702, and the upper cover B801 and the waste liquid shell 802, while maintaining assembly stability.
[0025] In the preferred technical solution, the water pumping end of the micro pump A703 is connected and installed with a U-shaped water pumping pipe 705, and the U-shaped water pumping pipe 705 passes through the water storage shell 702 and extends to the inside of the water storage shell 702. The water delivery end of the micro pump A703 is connected and installed with a U-shaped water delivery pipe 704. The two pipe heads of the U-shaped water delivery pipe 704 are fixedly provided with cleaning joints. The two water inlet pipes 5 are respectively connected to the two cleaning joints, and water is supplied by dual pumping and dual water delivery methods to provide flushing water pressure for the flushing hole group A1101 and the flushing hole group B1102.
[0026] In the preferred technical solution, the urinary catheter 401 is a water-absorbing gel ring tube, and its soft texture can reduce friction on the urethral opening and enhance tightness, thereby improving comfort.
[0027] In the preferred technical solution, the flushing hole group A1101 is distributed above the catheter 401, and the flushing hole group B1102 is distributed below the water-absorbing layer 403. This distribution is conducive to flushing the urethra and anus.
[0028] In the preferred technical solution, a convex sealing edge 402 is integrally formed on the periphery of the hollow box 4 , which can reduce the outflow of waste liquid from the periphery of the hollow box 4 .
[0029] When in use, the catheter 401 is covered on the urethra opening, and the wearing method is the same as the ordinary method. When the patient urinates, urine passes through the catheter 401 into the empty box 4, and the micro pump B803 is started. The urine can be pumped into the waste liquid housing 802 through the drainage tube 1201, the drainage connector 12, the drainage pipe 6, and the micro pump B803 for collection. When flushing, the micro pump A703 is started, and the clean water in the water storage housing 702 passes through the U-shaped water pumping pipe 705 and the micro pump A70 3. U-shaped water pipe 704, water inlet pipe 5, connector 10, and capillary group 11 finally flow out from flushing hole group A and flushing hole group B, which can be used to clean the urethra and anus. The waste liquid generated by cleaning is sucked into the independent waste liquid storage bin through the water absorption layer 403. The independent waste liquid storage bin is connected to the drainage connector 12 through the drainage capillary. Start the micro pump B803, and the waste liquid can be pumped into the waste liquid housing 802 through the drainage capillary 1201, the drainage connector 12, the drainage pipe 6, and the micro pump B803 for collection.
