Description
Technical Field
[0001] This invention relates to the field of flush toilets, specifically to a smart toilet with urine sample detection function. Background Technology
[0002] With the deep integration of smart home and health management industries, smart toilets have rapidly evolved from basic cleaning and flushing functions to home health monitoring. Urinalysis, as one of the three routine clinical tests, directly reflects the health status of the urinary and metabolic systems, serving as a core means for early disease screening and daily health management. However, traditional urinalysis requires users to manually collect urine samples at medical institutions, which is cumbersome, compromises privacy, and lacks timeliness. Therefore, integrating urine sample testing into smart toilets to enable routine home urinalysis has become an important direction for industry development, and related technological solutions are gradually being implemented.
[0003] However, existing smart toilets with integrated urine sample testing functions generally suffer from a core deficiency: insufficient accuracy in sample collection. In clinical testing, midstream urine is the gold standard sample for routine urinalysis. Initial urine is prone to carrying contaminants from the urethral opening, while terminal urine is prone to mixing with sediment at the bottom of the bladder; both can interfere with test results. However, most current technologies use a full-process urine collection mode, failing to differentiate between different stages of urination. The few solutions with segmented collection designs mostly employ fixed-delay start-stop structures, which cannot adapt to individual differences in urination flow rate and duration among different users. They cannot accurately identify the start and end points of midstream urine, making it difficult to obtain high-purity midstream urine samples. This directly leads to large errors in test results, failing to provide reliable reference for health assessments.
[0004] In addition, existing technologies suffer from a series of technical shortcomings in urine diversion and sample detection, further limiting the practicality and reliability of the products. Furthermore, current segmented collection structures generally lack anti-escape and anti-leakage designs, making urine collection prone to spillage and leakage. This not only results in insufficient sample collection but also contaminates the surrounding toilet structure and promotes bacterial growth. Simultaneously, the collected urine sample needs to be transferred to the detection unit through multiple channels, which is prone to secondary contamination and sample evaporation during the transfer process. Moreover, since the detection probes are mostly mechanically driven, insufficient contact between the probe and the urine sample can further amplify detection errors. The overall structure cannot achieve a sealed, end-to-end process for mid-stage urine screening, diversion, and detection, making it difficult to meet the needs of long-term, high-frequency, and accurate urine testing in home settings. Therefore, it is necessary to design a smart toilet with urine sample detection capabilities to solve these problems. Summary of the Invention
[0005] Therefore, it is necessary to provide a smart toilet with urine sample detection function to address the existing technical problems.
[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows:
[0007] A smart toilet with urine sample detection function includes the toilet body and also includes:
[0008] The front end of the toilet body has a perforation. A cone plate is installed at the lower end of the perforation by a motor. When the cone plate rotates, it opens the perforation to allow urine to pass through.
[0009] The lower end of the cone plate is equipped with a diffuser to prevent urine from escaping, the upper end of the cone plate is equipped with a pressure sensor to detect urine pressure, and the upper part of the perforation is equipped with an infrared sensor to detect urine flow rate.
[0010] A urine drainage mechanism for guiding midstream urine is provided on the side of the expansion plate away from the perforation. The urine drainage mechanism includes a drainage arc plate fixedly connected to the toilet body. One end of the drainage arc plate is dynamically sealed to the expansion plate, and a sampling tube for collecting urine is provided below the other end. The sampling tube is open at both ends.
[0011] The sampling tube is coaxially equipped with a sampling mechanism for urine detection. The sampling mechanism includes a plug that is dynamically sealed to the inner wall of the sampling tube, and a probe for urine analysis is coaxially equipped with the plug.
[0012] Furthermore, a removable operating window is provided in the middle of the toilet bowl wall, and the operating window is located next to the sampling tube.
[0013] Furthermore, two wedges are symmetrically arranged at the upper end of the drainage arc plate. An oblique part is formed on the side of the two wedges that are close to each other. The oblique parts of the two wedges are combined to form a trapezoidal channel. The large end of the trapezoidal channel points to the perforation and the small end points to the sampling tube.
[0014] The inclined portions of the two wedges have arc-shaped guide portions at the ends near the sampling tube. The two guide portions are combined to form an arc-shaped channel that is coaxial with the sampling tube.
[0015] Furthermore, a buffer arc plate is provided above the drainage arc plate and is fixedly connected to the toilet body. The buffer arc plate protrudes downward.
[0016] The lower end of the drainage arc plate is provided with a platform fixed to the drainage arc plate. The platform abuts against the upper end of the sampling tube, and the guide parts of the two wedges abut against the upper end of the platform.
[0017] Furthermore, a conical leak hole is provided in the middle of the stage, which is coaxial with the sampling tube. The larger end of the conical leak hole is set upwards, and the smaller end is set downwards.
[0018] Furthermore, ultraviolet disinfection lamps are arranged in an equidistant array in the middle of the buffer arc plate;
[0019] A nozzle connected to a water tank is installed in the middle of the end of the buffer arc plate near the perforation, and air nozzles for spraying high-pressure gas are installed on both sides of the nozzle.
[0020] Furthermore, a reinforcing sleeve is provided on the coaxial axis of the probe. The upper end of the reinforcing sleeve is fixedly connected to the plug, and the lower end is provided with an electric actuator fixedly connected to the toilet body. The output end of the electric actuator is fixedly connected to the reinforcing sleeve.
[0021] Furthermore, sealing rings are coaxially spaced and fitted onto the plug.
[0022] Furthermore, the upper end of the plug is equipped with a silicone beveled sleeve, the upper end of which is inclined, and the sampling tube has a liquid discharge clearance hole on the side near the water seal of the toilet body.
[0023] Furthermore, a liquid pump is installed on the side of the sampling tube near the water seal of the toilet body. The input end of the liquid pump is connected to the clearance hole on the side wall of the sampling tube, and the output end is connected to a drainage tube. The end of the drainage tube away from the liquid pump is connected to the water seal of the toilet body.
[0024] The beneficial effects of this invention compared to the prior art are:
[0025] Firstly, this device uses a dual-sensor linkage of infrared and pressure sensors to accurately identify different stages of urination, adapting to individual differences in urination among different users. It achieves directional screening of midstream urine by precisely opening and closing a cone plate driven by a motor, and with the anti-escape design of the expansion plate, it obtains high-purity midstream urine samples from the source, completely solving the problems of insufficient sample collection accuracy and large error in detection results in existing technologies, and providing a reliable detection basis for home health assessment.
[0026] Secondly, this device achieves sealed directional flow of midstream urine through a drainage arc plate connected to the expansion plate via dynamic sealing, preventing urine leakage and spillage. It eliminates the need for multi-channel sample transfer, allowing detection to be completed directly within the sampling tube via a coaxially moving probe. The dynamic sealing structure between the plug and the sampling tube prevents sample contamination and volatilization, ensuring full contact between the probe and the urine sample. This achieves sealed linkage of midstream urine screening, flow guidance, and detection, significantly improving detection reliability and device practicality. Attached Figure Description

[0038] To further understand the features, technical means, and specific objectives and functions achieved by the present invention, the present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
[0039] refer to Figures 1 to 9 A smart toilet with urine sample detection function includes a toilet body 1, and also includes:
[0040] The front end of the toilet body 1 has a perforation 2. A cone plate 3 is installed at the lower end of the perforation 2 by a motor. When the cone plate 3 rotates, it opens the perforation 2 to allow urine to pass through.
[0041] The lower end of the cone plate 3 is provided with a diffuser plate 4 to prevent urine from escaping, the upper end of the cone plate 3 is provided with a pressure sensor 5 to detect urine pressure, and the upper part of the perforation 2 is provided with an infrared sensor 6 to detect urine flow rate.
[0042] A urine-guiding mechanism 8 for guiding midstream urine is provided on the side of the expansion plate 4 away from the perforation 2. The urine-guiding mechanism 8 includes a drainage arc plate 9 fixedly connected to the toilet body 1. One end of the drainage arc plate 9 is dynamically sealed to the expansion plate 4, and a sampling tube 19 for collecting urine is provided below the other end. The two ends of the sampling tube 19 are connected.
[0043] A sampling mechanism 20 for urine detection is coaxially arranged in the sampling tube 19. The sampling mechanism 20 includes a plug 23 that is dynamically sealed to the inner wall of the sampling tube 19. A probe 21 for urine analysis is coaxially arranged in the plug 23.
[0044] When a user urinates, the infrared sensor 6 above the perforation 2 monitors the urine flow rate in real time, while the pressure sensor 5 at the top of the cone plate 3 simultaneously detects the urine impact pressure. The infrared sensor 6 and the pressure sensor 5 transmit the collected flow rate and pressure signals to the drive control terminal in real time. By analyzing the characteristic changes in flow rate and pressure, the three urination stages—initial urine, midstream urine, and terminal urine—are accurately distinguished. When the midstream urine stage is detected, the drive control terminal starts the motor to rotate the cone plate 3, opening the perforation 2 to allow midstream urine to pass through. The expansion plate 4 at the bottom of the cone plate 3 moves synchronously with the cone plate 3, forming a barrier against urine escape through its arc-shaped structure. This prevents midstream urine from spilling outwards, allowing only urine that meets the characteristics of midstream urine to pass through the perforation 2. This effectively blocks non-midstream urine and accurately filters midstream urine, ensuring the purity of the test sample from the source.
[0045] The midstream urine passing through the perforation 2 is guided by the expansion plate 4 and the drainage arc plate 9. The drainage arc plate 9 is fixedly connected to the toilet body 1, and one end of it maintains a dynamic seal with the expansion plate 4. It can maintain a sealed fit with the expansion plate 4 as the expansion plate 4 rotates, so as to prevent leakage of urine during the drainage process. The midstream urine is directed and converges without residue along the arc trajectory of the drainage arc plate 9 to the sampling tube 19 below its other end. The sampling tube 19 adopts a structure design with both ends through to ensure that the midstream urine enters the tube smoothly, completing the directional drainage and stable collection of urine samples, and providing a closed and clean sample environment for subsequent testing.
[0046] After midstream urine enters the sampling tube 19, the stopper 23, which is dynamically sealed to the inner wall of the sampling tube 19, drives the coaxially mounted analytical probe 21 to move smoothly along the axis of the sampling tube 19. The probe 21 directly and fully contacts the midstream urine sample inside the sampling tube 19, performing real-time analysis and detection of the urine sample components. The dynamic sealing structure between the stopper 23 and the inner wall of the sampling tube 19 ensures the airtightness of the urine sample inside the sampling tube 19, avoiding contamination and detection errors caused by urine evaporation and spillage during the detection process. At the same time, the coaxial movement design of the probe 21 enables full-range contact with the urine sample inside the tube, improving the accuracy of the detection results and realizing the fully automated completion of the entire process from midstream urine identification and collection to detection.
[0047] To facilitate the observation and replacement of the sampling tube 19 used for testing by operators, the following features are specifically designed:
[0048] like Figure 1 and Figure 4 As shown, a removable operating window 7 is provided in the middle of the toilet body 1, located beside the sampling tube 19. The operating window 7 adopts a snap-on sealing installation structure, and a waterproof sealing ring 24 is provided at the contact point with the toilet wall. During daily use, it can maintain the sealing state of the toilet interior and prevent odor leakage. When it is necessary to observe the operating status, clean, maintain, or replace the sampling tube 19, the user can quickly remove the operating window 7 and operate directly on the sampling tube 19 and surrounding structure without disassembling the entire toilet structure, greatly reducing the maintenance difficulty of the device and improving the convenience of use.
[0049] In order to guide the urine flowing through the upper end of the drainage arc plate 9 and prevent urine from overflowing and failing to flow into the sampling tube 19, the following features are specifically designed:
[0050] like Figure 7 , Figure 8 and Figure 9 As shown, two wedges 10 are symmetrically arranged at the upper end of the drainage arc plate 9. An inclined part 11 is formed on the side of the two wedges 10 that are close to each other. The inclined parts 11 of the two wedges 10 are combined to form a trapezoidal channel. The large end of the trapezoidal channel points to the perforation 2 and the small end points to the sampling tube 19.
[0051] The inclined portion 11 of the two wedges 10 is provided with an arc-shaped guide portion 12 at one end near the sampling tube 19. The two guide portions 12 are combined to form an arc channel coaxial with the sampling tube 19.
[0052] The inclined portions 11 of the two wedges 10 combine to form a trapezoidal channel, which can gather and guide the middle section of urine guided by the expansion plate 4, preventing the urine from overflowing to both sides, and directing the urine to flow in the direction of the sampling tube 19 along the inclined portions 11. The guide portions 12 of the two wedges 10 encircle and combine to form an arc-shaped channel coaxial with the sampling tube 19, which can further limit the gathered urine, so that the urine flows precisely into the opening of the sampling tube 19, avoiding sample loss and structural contamination caused by the urine deviating from the sampling tube 19, and ensuring sufficient sample collection.
[0053] To prevent urine from splashing upwards as it flows over the upper end of the drainage arc plate 9, the following features are specifically provided:
[0054] like Figure 6 and Figure 7 As shown, a buffer arc plate 13 is provided above the drainage arc plate 9 and is fixedly connected to the toilet body 1. The buffer arc plate 13 protrudes downward.
[0055] The lower end of the drainage arc plate 9 is provided with a platform 17 fixedly connected to the drainage arc plate 9. The platform 17 abuts against the upper end of the sampling tube 19, and the guide parts 12 of the two wedges 10 abut against the upper end of the platform 17.
[0056] The buffer arc plate 13 can buffer and block the urine flowing into the drainage arc plate 9, preventing urine from splashing upwards due to excessive flow velocity, and preventing urine from splashing out of the drainage area, causing contamination and sample loss. The platform 17 set at the lower end of the drainage arc plate 9 can provide stable support and limit for the sampling tube 19, and at the same time provide fixed support for the two wedges 10, ensuring that the guide part 12 of the wedge 10 is precisely aligned with the opening of the sampling tube 19, and ensuring the stability and accuracy of the drainage structure.
[0057] To facilitate the flow of urine into the sampling tube 19 via the guide section 12, the following features are specifically provided:
[0058] like Figure 7 As shown, a conical leak hole 18 is provided in the middle of the stage 17, coaxially aligned with the sampling tube 19. The larger end of the conical leak hole faces upward, and the smaller end faces downward. The larger end of the conical leak hole 18 receives the urine collected by the guide part 12, which can expand the urine receiving range and prevent urine overflow. At the same time, the guiding effect of the conical structure guides the urine smoothly along the hole wall into the sampling tube 19 at the lower end, further improving the smoothness of urine flow, preventing urine residue on the surface of the stage 17, and ensuring that all collected urine samples enter the sampling tube 19 for subsequent testing.
[0059] To ensure the removal of residual urine from the catheterization device 8 after the test, the following features are specifically included:
[0060] like Figure 6 , Figure 8 and Figure 9 As shown, ultraviolet disinfection lamps 15 are arranged in an equiangular array in the middle of the buffer arc plate 13;
[0061] A nozzle 14 connected to a water tank is located in the middle of the end of the buffer arc plate 13 near the perforation 2. Air nozzles 16 for spraying high-pressure gas are located on both sides of the nozzle 14. After testing, the nozzle 14 sprays flushing water to thoroughly rinse the drainage structure and remove residual urine. Then, the air nozzles 16 spray high-pressure gas to dry the surface water. Finally, the ultraviolet disinfection lamp 15 irradiates the drainage arc plate 9 and wedge block 10, sterilizing them from all angles to prevent bacterial growth from residual urine. This achieves a complete cleaning, drying, and sterilization process for the catheterization mechanism 8.
[0062] To facilitate the movement of probe 21 during the testing process and to allow for the release of urine from sampling tube 19 after the testing is completed, the following features are specifically included:
[0063] like Figure 7 As shown, a reinforcing sleeve 26 is coaxially arranged on the probe 21. The upper end of the reinforcing sleeve 26 is fixedly connected to the plug 23, and the lower end is provided with an electric actuator 22 fixedly connected to the toilet body 1. The output end of the electric actuator 22 is fixedly connected to the reinforcing sleeve 26.
[0064] The reinforcing sleeve 26 provides stable protection for the probe 21, preventing it from shifting or shaking during movement and ensuring the coaxiality of the probe 21 and the sampling tube 19. The electric actuator 22, through its extension and retraction at the output end, can smoothly move the reinforcing sleeve 26, the plug 23, and the probe 21 along the axis of the sampling tube 19, achieving precise adjustment of the detection position and the expulsion of urine after detection.
[0065] To achieve a sealed connection between the plug 23 and the sampling tube 19, the following features are specifically provided:
[0066] like Figure 7 As shown, sealing rings 24 are coaxially spaced and fitted onto the stopper 23. The sealing rings 24 are made of medical-grade silicone, and their outer rings fit tightly against the inner wall of the sampling tube 19. This ensures a tight seal between the stopper 23 and the inner wall of the sampling tube 19 during the movement of the stopper 23. This prevents urine sample from leaking through the gap between the stopper 23 and the sampling tube 19 during the testing process, ensuring the airtightness of the testing environment. It also completely scrapes away any residual urine from the inner wall of the sampling tube 19 when the stopper 23 moves to expel urine, improving the thoroughness of urine expulsion.
[0067] To ensure smooth drainage of the liquid in sampling tube 19, the following features are specifically included:
[0068] like Figure 7 As shown, the upper end of the stopper 23 is provided with a silicone beveled sleeve 25. The upper end of the beveled sleeve 25 is inclined, and the sampling tube 19 has a drainage hole for discharging liquid on the side near the water seal of the toilet body 1. The beveled sleeve 25 can guide the urine when it enters the sampling tube 19, preventing urine from accumulating at the upper end of the stopper 23. At the same time, when the stopper 23 moves to discharge urine, its inclined structure can reduce the flow resistance of urine and improve the discharge efficiency. When the stopper 23 moves above the drainage hole, the drainage hole on the side wall of the sampling tube 19 allows the urine in the sampling tube 19 to be discharged smoothly through the drainage hole without having to move the stopper 23 in the opposite direction, simplifying the urine discharge process and avoiding urine residue.
[0069] To prevent water in the water seal from flowing back into the sampling tube 19, the following features are specifically designed:
[0070] like Figure 7As shown, a liquid pump 28 is installed on the side of the sampling tube 19 near the water seal of the toilet body 1. The input end of the liquid pump 28 is connected to the clearance hole on the side wall of the sampling tube 19, and the output end is connected to the drainage tube 27. The end of the drainage tube 27 away from the liquid pump 28 is connected to the water seal of the toilet body 1. After the test is completed, the negative pressure generated by the liquid pump 28 quickly draws out the urine in the sampling tube 19 and drains it into the toilet water seal through the drainage tube 27, realizing the active and thorough discharge of urine and avoiding the growth of bacteria in the sampling tube 19. At the same time, it can be used in conjunction with the movement of the plug 23 to further improve the urine discharge efficiency and ensure the cleanliness of the inside of the sampling tube 19.
[0071] The detailed working principle of this device is as follows: When a user urinates, the infrared sensor 6 above the perforation 2 monitors the urine flow rate in real time, and the pressure sensor 5 at the top of the cone plate 3 simultaneously detects the urine impact pressure. The two sensors transmit the collected flow rate and pressure signals to the drive control end in real time, and accurately distinguish the three urination stages of initial urine, midstream urine and terminal urine by the characteristic changes of flow rate and pressure.
[0072] In the initial urine stage, the cone plate 3 remains closed, and the initial urine flows directly into the toilet water seal. When the midstream urine stage is detected, the drive control unit starts the motor to rotate the cone plate 3 and open the perforation 2. The expansion plate 4 at the lower end of the cone plate 3 moves synchronously with the cone plate 3, forming a barrier against urine escape through the arc structure, preventing the midstream urine from overflowing to the surrounding area, and only allowing urine that meets the characteristics of midstream urine to pass through the perforation 2. The midstream urine passing through the perforation 2 is directionally guided by the expansion plate 4 to the drainage arc plate 9. The dynamic seal between the drainage arc plate 9 and the expansion plate 4 prevents urine leakage. After the urine is gathered by the trapezoidal channel of the wedge block 10 and limited by the arc channel, it flows precisely into the sampling tube 19 through the conical leakage hole 18 of the platform 17. The buffer arc plate 13 simultaneously blocks urine splashing, completing the sealed drainage and collection of the urine sample. After midstream urine enters the sampling tube 19, the electric actuator 22 moves the stopper 23 and the coaxial probe 21 along the axis of the sampling tube 19, ensuring that the probe 21 makes full contact with the urine sample to complete real-time detection. The sealing ring 24 of the stopper 23 ensures the sealing performance during the detection process. After the detection is completed, the electric actuator 22 moves the stopper 23, and the liquid pump 28 discharges the urine in the sampling tube 19 into the toilet water seal through the clearance hole. Then, the nozzle 14 sprays flushing water, the air nozzle 16 sprays high-pressure gas to clean and dry the guide structure, and the ultraviolet disinfection lamp 15 completes the sterilization, realizing the fully automated operation of the device and completing the entire process of midstream urine identification, collection, detection, and cleaning.
[0073] The above embodiments only illustrate one or more implementations of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this patent should be determined by the appended claims.
