Description

Technical Field

[0001] This invention relates to the field of smart toilets, specifically to a toilet that integrates contactless urine detection and intelligent health management. Background Technology

[0002] With the deep integration of smart home and health management industries, smart toilets with integrated urine detection functions are gradually becoming a market hotspot. However, compared with medical urine testing devices, toilets with integrated urine detection functions still have many problems in practical applications. For example, existing solutions mostly use front-end diversion channels or direct flow sampling methods. When men urinate standing up, the urine flow is concentrated, and the sampling success rate is acceptable. However, when women urinate sitting down, the urine flow is dispersed and the landing point is variable. The diversion channel, which passively stores urine, is difficult to effectively collect urine, resulting in insufficient sampling success rate and making it impossible to achieve universal applicability. At the same time, the diversion channel has a complex structure, which easily accumulates urine and dirt, breeds bacteria, and is difficult to clean thoroughly, posing a serious risk of cross-contamination.

[0003] Secondly, in clinical testing, midstream urine is the gold standard for ensuring accurate results. However, most current technologies use fixed-delay methods or single-point pressure sensors to identify midstream urine, which cannot adapt to the differences in urination rhythms among different users. Especially in scenarios where urine flows along the toilet bowl wall, traditional pressure sensors cannot detect effective impact force, and ordinary infrared sensors are easily affected by reflections and water droplets, resulting in insufficient accuracy in midstream urine identification. Often, the collected urine is contaminated with pre-urethral contaminants or contains bladder deposits, leading to significant errors in the test results and failing to provide a reliable basis for health assessment.

[0004] In addition, existing urine testing toilets only perform a simple water flush on the drainage channel, neglecting residual urine and protein in the integrated testing device inside the toilet. Long-term use can lead to scaling in the pipes and decreased testing accuracy. While some solutions using disposable testing consumables reduce the risk of contamination, they significantly increase long-term operating costs for users. Furthermore, cleaning the toilet's inner wall solely with water not only fails to thoroughly remove residual bacteria and viruses, posing health risks, but also the lack of targeted cleaning of the urine collection area can affect subsequent tests. Therefore, we need to design a smart toilet for urine testing that provides reliable sampling and thorough cleaning without requiring any contact with the user. Summary of the Invention

[0005] Therefore, it is necessary to provide a toilet that integrates contactless urine detection and intelligent health management to address the existing technological problems.

[0006] To solve the problems of the prior art, the technical solution adopted by the present invention is as follows: A toilet integrating contactless urine detection and intelligent health management, comprising: A display screen electrically connected to the controller is installed next to the water tank. The inner wall of the toilet has a gentle slope and is equipped with miniature fans arranged in an array along the circumference. Above the miniature fans is an ultraviolet light strip arranged in a ring along the glaze of the inner wall of the toilet. An annular cavity is provided on the side of the gentle slope away from the toilet water seal. An annular water pipe connected to the water tank is provided at the upper part of the annular cavity. Two non-contact urine detection mechanisms are symmetrically arranged in the middle of the annular cavity along the circumference. The non-contact urine testing device includes a detection tube connected to a ring-shaped water pipe. The detection tube is equipped with a detection head. The lower end of the detection tube is connected to a sampling needle and a drain pipe located above the sampling needle. The sampling needle is slidably connected to the inner wall of the toilet with the needle tip pointing downwards and the needle hole pointing upwards at an angle. The outlet of the drain pipe extends out of the inner wall of the toilet. A negative pressure tube is connected to the side of the test tube. When the negative pressure tube draws out the air inside the test tube, the sampling needle draws the urine flowing down the gentle slope into the test tube.

[0007] Furthermore, each detection tube is equipped with a capacitive liquid level sensor on the side closest to the gentle slope, and a thin-film pressure sensor is installed next to the capacitive liquid level sensor. The detection end of the thin-film pressure sensor is located on the glazed surface of the gentle slope.

[0008] Furthermore, the sampling needle is coaxially provided with a rubber sleeve that is fixed to the inner wall of the toilet, and the sampling needle and the rubber sleeve are dynamically sealed and slidably connected.

[0009] Furthermore, a capillary tube is provided at one end of the sampling needle near the detection tube, and the capillary tube is connected to the lower end of the detection tube; A shuttle-shaped tube is provided on the side of the sampling needle near the capillary tube. One end of the shuttle-shaped tube is connected to the sampling needle, and the other end is connected to the capillary tube. The inner walls of the capillary tube and the shuttle-shaped tube are respectively provided with a hydrophobic coating.

[0010] Furthermore, electric telescopic rods are inclinedly installed on both sides of the spindle tube, and a pad is fixedly connected to the spindle tube coaxially. The output ends of the two electric telescopic rods are fixedly connected to the two ends of the pad respectively. A tube support is provided on the side of the rubber sleeve near the pad, and the tube support is fixed to the inner wall of the annular cavity. Two guide rods are fixed to the side of the tube support near the pad, and the two guide rods are slidably connected to the pad. A spring is sleeved on the outside of the guide rod, with one end of the spring fixed to the tube support and the other end fixed to the pad.

[0011] Furthermore, a conical sleeve is coaxially fixed to the lower end of the inside of the detection tube.

[0012] Furthermore, the outlet of the drain tube is positioned downwards towards the sampling needle, and the outlet of the drain tube is a strip-shaped hole.

[0013] Furthermore, a solenoid valve is installed on one side of the drain pipe at the lower end of the detection tube. The output end of the solenoid valve is connected to the strip hole, and the input end is connected to the detection tube.

[0014] Furthermore, a branch port communicating with the upper part of the negative pressure tube is opened on one side of the upper part of the detection tube. A piston is provided in the dynamic sealing sleeve inside the negative pressure tube, and a finger cylinder is provided at the lower end of the negative pressure tube. The lower end of the piston is fixedly connected to the output end of the finger cylinder.

[0015] Furthermore, a one-way valve is installed at the upper end of the detection tube. The input end of the one-way valve is connected to the annular water pipe, and the output end is connected to the detection tube.

[0016] The beneficial effects of this invention compared to the prior art are: Firstly, this solution completely solves the problems of low sampling success rate and gender differences in existing technologies by using the gentle slope inner wall flow sampling and the dual-mechanism posture adaptation design. The gentle slope transforms the dispersed urine flow into a uniform and stable continuous liquid flow. The two non-contact urine detection mechanisms set symmetrically along the circumference correspond to the urine flow paths of standing and sitting defecation, respectively. Regardless of the user's posture, sampling can be completed accurately, greatly improving the sampling success rate. At the same time, the negative pressure suction principle is used to actively collect midstream urine in the flowing state, avoiding the dilution and contamination problems of static storage liquid. The representativeness of the sample is significantly enhanced, providing a reliable and accurate guarantee for home health monitoring. Secondly, this solution constructs a closed-loop cleaning system that reuses the bidirectional gas-liquid cleaning function of the detection tube and the self-cleaning function of the toilet, fundamentally eliminating the risk of cross-contamination. After the test is completed, the detection tube is first rinsed with cleaning water, and then the sampling needle is purged in reverse using stored compressed air, achieving thorough cleaning of the detection tube and sampling needle. In addition, this solution directly utilizes the toilet's built-in flushing, micro-fan drying, and ultraviolet light disinfection functions to comprehensively disinfect the sampling environment of midstream urine. The cleaning water flowing out of the detection tube will clean the sampling area again, eliminating the need for an additional independent disinfection device for the detection structure, greatly simplifying the system structure and reducing manufacturing costs and long-term maintenance difficulties.

[0019] 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.

[0020] refer to Figures 1 to 8 A toilet integrating contactless urine detection and intelligent health management, comprising: A display screen 1 electrically connected to the controller is installed next to the water tank. The inner wall of the toilet is a gently sloping surface 2 and a miniature fan 6 is arranged in an array along the circumference. Above the miniature fan 6, an ultraviolet light strip 5 is arranged in a ring along the glaze of the inner wall of the toilet. An annular cavity 7 is provided on the side of the gentle slope surface 2 away from the toilet water seal. An annular water pipe 29 connected to the water tank is provided on the upper part of the annular cavity 7. Two non-contact urine detection mechanisms 8 are symmetrically arranged in the middle of the annular cavity 7 along the circumferential direction. The non-contact urine testing device 8 includes a detection tube 18 connected to a ring water pipe 29. A detection head 20 is installed inside the detection tube 18. A sampling needle 12 and a drain pipe 21 located above the sampling needle 12 are connected to the lower end of the detection tube 18. The sampling needle 12 is slidably connected to the inner wall of the toilet with the needle tip pointing downward and the needle hole pointing upward. The outlet of the drain pipe 21 extends out of the inner wall of the toilet. A negative pressure tube 25 is connected to the side of the detection tube 18. When the negative pressure tube 25 draws out the air inside the detection tube 18, the sampling needle 12 draws the urine flowing down the gentle slope 2 into the detection tube 18.

[0021] When a user uses the toilet, the system automatically starts in response to the user's actions, and the display screen 1, electrically connected to the controller next to the water tank, simultaneously enters standby mode. During urination, urine flows naturally downwards along the gentle slope 2 of the toilet bowl's inner wall. The structural design of the gentle slope 2 effectively slows down the flow of urine, ensuring a continuous and stable flow, providing a foundation for subsequent urine collection. Two non-contact urine detection mechanisms 8, symmetrically arranged along the circumference of the annular cavity 7, are adapted to the different urine flow paths for standing and sitting postures, ensuring accurate coverage of the urine flow area regardless of the user's posture, providing structural assurance for reliable sampling.

[0022] When urine flows to the sampling area of ​​the corresponding contactless urine testing device 8, the sampling needle 12, which is slidably connected to the inner wall of the toilet, extends from the inner wall. The needle tip is tilted downwards and the needle hole upwards, allowing it to be precisely submerged in the urine flowing down the gentle slope 2. At this time, the negative pressure tube 25, connected to the side of the detection tube 18, is activated, drawing out some air from inside the detection tube 18 and temporarily storing it, creating a stable negative pressure environment inside the detection tube 18. Under the continuous action of negative pressure, the urine at the needle tip is smoothly drawn into the detection tube 18. Once the sample volume meets the testing requirements, the detection head 20 inside the detection tube 18 immediately performs multi-index analysis on the urine sample. The test results are processed by the controller and transmitted in real time to the display screen 1 next to the water tank for clear display. The entire sampling and testing process requires no manual operation from the user and is completed completely contactlessly.

[0023] After testing, the system automatically initiates a closed-loop cleaning procedure. The annular water pipe 29, connected to the water tank, injects cleaning water into the upper part of the detection tube 18. Simultaneously, the drain pipe 21 at the lower end of the detection tube 18, located above the sampling needle 12, opens, allowing the cleaning water, carrying the urine from the test, to be quickly discharged from the drain pipe 21, completing the initial rinsing of the inner wall of the detection tube 18. Subsequently, the negative pressure pipe 25 injects previously extracted and stored air back into the detection tube 18. The high-pressure airflow pushes the remaining cleaning water outward through the sampling needle 12, achieving thorough cleaning of the inside and tip of the sampling needle 12. After the user finishes using the toilet and leaves, the toilet automatically flushes to clean the inner wall. The micro-fans 6, arranged in a circular array along the circumference, then start, forming a ring-shaped airflow to dry any remaining liquid on the inner wall. Finally, the ultraviolet light strip 5, arranged in a ring above the micro-fans and along the glazed surface of the toilet's inner wall, turns on, irradiating and disinfecting the toilet's inner wall from all angles, completing the cleaning and sterilization process for the next use.

[0024] To identify midstream urine, the following features were specifically designed: like Figure 2 and Figure 3As shown, each detection tube 18 is equipped with a capacitive liquid level sensor 3 on the side near the gentle slope surface 2, and a thin film pressure sensor 4 is provided next to the capacitive liquid level sensor 3. The detection end of the thin film pressure sensor 4 is located on the glaze surface of the gentle slope surface 2.

[0025] When a user uses the toilet, the capacitive liquid level sensor 3 detects in real time whether there is a urine film covering the gentle slope surface 2, and the thin film pressure sensor 4 simultaneously detects the slight pressure changes caused by the flow of the liquid film. When the capacitive liquid level sensor 3 and the thin film pressure sensor 4 simultaneously detect a continuous and stable signal, it is determined to be the midstream urine stage, and the system triggers the sampling action. When the signal decays or disappears, it is determined to be the late urine stage, and the sampling is immediately terminated to ensure that a high-purity midstream urine sample is collected.

[0026] To provide a sealed protection for the sampling needle 12 in its retracted state, the following features are specifically designed: like Figure 3 and Figure 4 As shown, a rubber sleeve 9 is coaxially arranged with the sampling needle 12 and fixed to the inner wall of the toilet. The sampling needle 12 and the rubber sleeve 9 are dynamically sealed and slidably connected.

[0027] When the sampling needle 12 is retracted, the rubber sleeve 9 completely wraps around the tip and body of the sampling needle 12, completely isolating the inside of the detection tube 18 from the toilet's internal environment, preventing sewage, odors and bacteria from entering the detection tube 18. When the sampling needle 12 is extended, the rubber sleeve 9 maintains a dynamic seal with the outer wall of the sampling needle 12, preventing urine from seeping into the annular cavity 7.

[0028] To supplement the connection structure between the sampling needle 12 and the detection tube 18, the following features are specifically provided: like Figure 4 and Figure 8 As shown, a capillary tube 17 is provided at one end of the sampling needle 12 near the detection tube 18, and the capillary tube 17 is connected to the lower end of the detection tube 18; A shuttle-shaped tube 13 is provided on the side of the sampling needle 12 near the capillary tube 17. One end of the shuttle-shaped tube 13 is connected to the sampling needle 12, and the other end is connected to the capillary tube 17. The inner walls of the capillary tube 17 and the shuttle-shaped tube 13 are respectively provided with hydrophobic coatings.

[0029] During urine collection, the flexible structure of the capillary tube 17 can adapt to the extension and retraction of the sampling needle 12, avoiding tube breakage. The end of the fusiform tube 13 closest to the sampling needle 12 is the small end. After urine enters, it flows into the central expansion chamber through the small end, and the flow rate naturally slows down, which can effectively eliminate air bubbles generated by urine flow fluctuations and avoid air bubbles interfering with detection accuracy. The hydrophobic coating on the inner wall of the capillary tube 17 and the fusiform tube 13 makes the urine flow in a spherical shape, with no residue adhering to the wall, preventing cross-contamination.

[0030] To achieve stable displacement of the sampling needle 12, the following features are specifically designed: like Figure 4 and Figure 8 As shown, electric telescopic rods 11 are inclinedly arranged on both sides of the shuttle tube 13, and a pad frame 10 is coaxially fixed to the shuttle tube 13. The output ends of the two electric telescopic rods 11 are fixed to the two ends of the pad frame 10 respectively. A tube frame 14 is provided on the side of the rubber sleeve 9 near the pad frame 10. The tube frame 14 is fixedly connected to the inner wall of the annular cavity 7. Two guide rods 15 are fixedly connected on the side of the tube frame 14 near the pad frame 10. The two guide rods 15 are slidably connected to the pad frame 10 respectively. A spring 16 is sleeved on the outside of the guide rod 15. One end of the spring 16 is fixedly connected to the tube frame 14 and the other end is fixedly connected to the pad frame 10.

[0031] As the sampling needle 12 moves, the two electric telescopic rods 11 synchronously push the pad frame 10 to move smoothly along the guide rod 15, causing the sampling needle 12 to overcome the resistance of the spring 16 and extend out of the rubber sleeve 9, accurately reaching the sampling position on the gentle slope 2; the guide rod 15 ensures that the sampling needle 12 does not deviate during the movement, and the spring 16 provides buffering and reset assistance, making the extension and retraction of the sampling needle 12 more stable and reliable.

[0032] To facilitate the downward flow of liquid inside the detection tube 18, the following features are specifically designed: like Figure 6 and Figure 7 As shown, a conical sleeve 19 is coaxially fixed to the lower end of the inside of the detection tube 18. During the detection and cleaning process, the conical inner wall of the conical sleeve 19 can guide urine and cleaning water to converge towards the center of the bottom of the detection tube 18, avoiding liquid accumulation at the bottom corners of the detection tube 18, ensuring that the detection head 20 can fully contact the urine sample, and improving the emptying efficiency during cleaning, leaving no dead corners.

[0033] To prevent urine from flowing back into the drain pipe 21 from top to bottom, and also to clean the aspiration area of ​​the sampling needle 12, the following features are specifically designed: like Figure 3 As shown, the outlet of the drain pipe 21 is oriented downwards toward the sampling needle 12, and the outlet of the drain pipe 21 is a strip-shaped hole 22. During the sampling and detection stages, the downward orientation of the outlet of the drain pipe 21 effectively prevents urine from flowing back into the drain pipe 21. During the cleaning stage, cleaning water is sprayed out in a fan shape from the strip-shaped hole 22 to cover the outer surface of the sampling needle 12 and the surrounding gentle slope area 2, achieving simultaneous cleaning of the exterior of the sampling needle 12 and the sampling environment.

[0034] To ensure timely emptying of urine and subsequent cleaning fluid from the detection tube 18, the following features are specifically included: like Figure 7As shown, a solenoid valve 23 is installed on one side of the drain pipe 21 at the lower end of the detection tube 18. The output end of the solenoid valve 23 is connected to the strip-shaped hole 22, and the input end is connected to the detection tube 18. During the sampling and detection stages, the solenoid valve 23 remains closed to ensure that a sealed negative pressure environment is formed inside the detection tube 18. During the cleaning stage, the solenoid valve 23 automatically opens, allowing the urine and cleaning water in the detection tube 18 to be drained quickly and thoroughly, preventing liquid accumulation.

[0035] To supplement the detailed structure of the negative pressure pipe 25, the following features are also provided: like Figure 5 and Figure 6 As shown, a branch port 24 communicating with the upper part of the negative pressure tube 25 is opened on one side of the upper part of the detection tube 18. A piston 27 is provided in the dynamic sealing sleeve inside the negative pressure tube 25. A finger cylinder 26 is provided at the lower end of the negative pressure tube 25. The lower end of the piston 27 is fixedly connected to the output end of the finger cylinder 26.

[0036] During sampling, the finger cylinder 26 drives the piston 27 to move downward, drawing air out of the detection tube 18 through the branch port 24 to form a stable negative pressure. During the cleaning backflushing stage, the finger cylinder 26 drives the piston 27 to move upward, rapidly injecting air from the upper end of the piston 27 into the detection tube 18 to form a high-pressure airflow, which pushes the residual liquid out of the sampling needle 12.

[0037] To prevent the cleaning water in the annular water pipe 29 from being prematurely poured into the detection pipe 18 when the negative pressure pipe 25 is working, the following features are specifically designed: A one-way valve 28 is installed at the upper end of the detection tube 18. The input end of the one-way valve 28 is connected to the annular water pipe 29, and the output end is connected to the detection tube 18. During the sampling stage, when a negative pressure is formed in the detection tube 18, the one-way valve 28 automatically closes to prevent the cleaning water in the annular water pipe 29 from being prematurely drawn into the detection tube 18 and contaminating the sample. During the cleaning stage, when the water supply pressure of the annular water pipe 29 is greater than the opening pressure of the one-way valve 28, the one-way valve 28 automatically opens, and the cleaning water flows into the detection tube 18 for rinsing.

[0038] The detailed working principle of this toilet is as follows: The system automatically starts after the user sits down, the display screen 1 next to the water tank enters standby mode, and the two contactless urine detection mechanisms 8 enter standby modes corresponding to the standing and sitting postures, respectively. When the user urinates, the urine forms a continuous liquid film flowing downwards along the inner wall of the gentle slope 2. The gentle slope 2 effectively slows down the urine flow, preventing splashing and interruption of flow. The capacitive liquid level sensor 3 and the thin-film pressure sensor 4, corresponding to the urination posture, monitor the liquid film status in real time. When both simultaneously detect a continuous and stable signal, it is determined to be the midstream urine stage, and the system triggers a sampling command.

[0039] Upon receiving the sampling command, the electric telescopic rod 11 of the corresponding contactless urine testing mechanism 8 synchronously pushes the pad 10 to move smoothly along the guide rod 15, causing the sampling needle 12 to overcome the resistance of the spring 16 and extend out of the rubber sleeve 9, with the needle tip precisely submerged in the urine film on the gentle slope 2. At this time, the finger cylinder 26 drives the piston 27 in the negative pressure tube 25 to move downward, drawing air out of the detection tube 18 through the branch port 24 to form a stable negative pressure. Under the action of negative pressure, urine enters the small end of the shuttle tube 13 through the sampling needle 12, flows into the middle expansion chamber, and the flow rate naturally slows down, effectively eliminating air bubbles generated by urine flow fluctuations. It is then smoothly delivered to the detection tube 18 through the capillary tube 17, with the hydrophobic coating on the inner wall preventing urine residue from adhering to the wall throughout the process. When the sample volume reaches the testing requirements, the detection head 20 at the bottom of the detection tube 18 fully contacts the urine under the guiding action of the conical sleeve 19, completing multi-index biochemical analysis. The test results are processed by the controller and displayed in real time on the display screen 1.

[0040] After the test is completed, the solenoid valve 23 automatically opens, the finger cylinder 26 stops pumping air, and the urine in the test tube 18 is discharged through the drain pipe 21 under gravity. Then, the annular water pipe 29 supplies water, and the one-way valve 28 opens under water pressure, allowing cleaning water to flow into the test tube 18 to thoroughly rinse the inner wall. The cleaning water, carrying residual urine, is sprayed out in a fan shape from the strip-shaped hole 22 of the drain pipe 21, simultaneously rinsing the exterior of the sampling needle 12 and the surrounding gentle slope 2. After rinsing, the finger cylinder 26 drives the piston 27 to move upward, injecting the stored compressed air in reverse into the test tube 18, forming a high-pressure airflow that propels the residual cleaning water from the tip of the sampling needle 12 at high speed, thoroughly removing any residue inside the sampling needle 12. After cleaning, the electric telescopic rod 11 is de-energized, the spring 16 drives the sampling needle 12 to smoothly retract into the rubber sleeve 9, and the solenoid valve 23 and the one-way valve 28 close simultaneously, restoring the sealed state. After the user leaves the seat, the toilet automatically flushes to clean the inner wall. The micro fans 6 in the circular array start to form a ring airflow to dry the residual moisture. Finally, the ring ultraviolet light strip 5 turns on to disinfect in all directions, completing the fully automated operation of the entire life cycle.

[0041] 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.
