Abstract
Description
Technical Field
[0001] This invention relates to the field of smart toilet technology, and more specifically to an automatic waste recording system for a smart toilet. Background Technology
[0002] The demand for smart toilets in daily health monitoring and convenient medical services is increasingly prominent. However, in health management, especially in the diagnosis and follow-up of diseases related to the digestive and urinary systems, physiological indicator data obtained solely from instrument detection is sometimes insufficient. Clinicians often need to combine the patient's subjective symptom descriptions with visual information such as the shape, color, and texture of bodily waste (including feces and urine) for comprehensive judgment. Currently, patients usually rely on their recollection to describe bodily waste to doctors, which has significant drawbacks: first, memory is prone to fading or distortion, leading to inaccurate descriptions; second, the lack of objective imaging records fails to provide doctors with intuitive reference data, posing challenges to effective communication between doctors and patients and accurate diagnosis.
[0003] To address this issue, some solutions have emerged on the market designed to record soiling conditions, such as apps or devices that allow users to manually photograph soiling with their smartphones. However, these solutions rely on active user intervention, making the process cumbersome and significantly lacking in user experience: users are prone to forgetting, feeling inconvenienced, or finding it unhygienic, leading to interrupted recording or data loss, making it difficult to create a long-term, systematic, and complete soiling log.
[0004] Therefore, this application studies an automatic waste recording system for a smart toilet, which automatically takes photos through sensing signals to record waste automatically, providing intuitive and reliable evidence. Summary of the Invention
[0005] In order to automatically take photos through sensing signals and realize automatic recording of waste, providing intuitive and reliable evidence, this application provides an automatic waste recording system for a smart toilet.
[0006] This application provides an automatic waste recording system for a smart toilet, which adopts the following technical solution: An automatic waste recording system for a smart toilet includes a toilet body, a base, a main control board, a sensing module, and a camera module. The sensing module senses the user's usage status and sends a shooting command to the main control board based on the usage status. The camera module is mounted on the base or the toilet body, with the shooting direction facing the water cover area inside the toilet body. The main control board is electrically connected to the sensing module and the camera module. After receiving the shooting command from the sensing module, the main control board controls the camera module to immediately or after a delay to capture an image of the water cover area and generate an image.
[0007] By adopting the above technical solution and setting up a linkage control mechanism between the sensing module, the shooting module and the main control board, the image acquisition and recording of the waste can be automatically triggered after the user uses the toilet. This achieves objective and imperceptible recording of waste images, fundamentally solving the problems of inconvenience, data loss and inaccuracy caused by relying on manual operation and subjective memory of the user. It provides intuitive and reliable objective evidence for clinical diagnosis.
[0008] Optionally, the coverage area of the shooting module is greater than or equal to the area of the water cover area; and a single shooting command takes continuous photos to obtain at least two photos; an image storage device is also provided for storing images, and storing data including at least one of the shooting time and shooting device information. The image storage device is located on the toilet or on the server. When the number of images stored in the image storage device exceeds a preset threshold, the image data with the earliest storage time is automatically deleted or replaced.
[0009] By adopting the above technical solution, it is ensured that the images of dirt are captured completely and clearly, which improves the success rate of recording and image quality. At the same time, due to cost reasons, the local storage space is limited and can only save the most recent images. This makes it convenient to query the most recent records in special circumstances and can also prevent the system from querying records and making correct decisions after emergencies (power outages or data interruptions). This ensures that the system can operate stably for a long time and retain the most recent valid records.
[0010] Optionally, the sensing module is a seat sensor installed inside the toilet seat, used to detect the user's sitting and / or getting up actions, and to generate and issue a shooting command when a getting up signal or a set of signals of sitting up and then getting up is detected; Alternatively, the sensing module may be a microwave sensing module installed inside the toilet shell. The sensing module is used to detect whether a user enters and / or leaves the toilet area, and / or, the sensing module is used to detect whether there is a person in the toilet area, and generates and issues a shooting command after detecting that the user has left the toilet area, or generates and issues a shooting command if the user enters the toilet area and then leaves the toilet area, or generates and issues a shooting command if the user enters the toilet area, stays in the toilet area for a preset time and then leaves the toilet area. Alternatively, the sensing module may include a seating sensor disposed within the toilet seat and a microwave sensing module disposed within the toilet shell. The seating sensor is used to detect the user's sitting and / or getting up actions, and the microwave sensing module is used to detect whether the user enters and / or leaves the toilet area. Alternatively, the microwave sensing module is used to detect whether there is a person within the toilet area, and generates and issues a shooting command when the seating sensor detects an getting up signal and the microwave sensing module detects that the user has left the toilet area.
[0011] By adopting the above technical solution, the user's end-of-use status can be accurately and seamlessly determined, thereby automatically triggering shooting at the optimal time, further improving the accuracy of automatic recording and the seamless user experience, and avoiding accidental or missed triggering.
[0012] Optionally, the shooting module includes a housing, a light-transmitting window, and a camera; the light-transmitting window is a transparent structure, integrally or separately disposed with the housing, and sealed and fixedly connected, the light-transmitting window and the housing together forming a sealed inner cavity; the camera is disposed in the inner cavity, its lens facing the light-transmitting window; it also includes a second driving device, which is connected to the shooting module and is used to drive the shooting module to perform telescopic movement. After the main control board receives the shooting command from the sensing module, the second driving device drives the shooting module to extend into the toilet bowl to take a picture. After the picture is taken, the shooting module retracts to its initial state; the shooting module is disposed in the body carrying a sealing cover. When the shooting module extends, the sealing cover opens; when the shooting module retracts, the sealing cover closes to form a sealed inner cavity.
[0013] By adopting the above technical solutions, the sealed structure design effectively protects the camera from the erosion of the humid and dirty environment inside the toilet, ensuring the long-term reliability of the shooting module. The second drive device allows the camera to be inserted into the toilet to obtain a better shooting angle when shooting, and retracts for protection when not in use, further optimizing the image acquisition effect and extending the life of the device. It also includes a sealing cover that can be sealed to further protect the camera from environmental pollution.
[0014] Optionally, it also includes a drive unit and a lighting module; the drive unit is connected to the main control board and is used to drive the toilet lid and / or seat to open and close; the lighting module is mounted on the base and connected to the main control board; after receiving the shooting command from the sensing module, the main control board controls the drive unit to immediately or after a delay to close the lid and / or seat, and simultaneously turn on the lighting module; or, after closing the lid and / or seat, the lighting module is turned on, and then the shooting module is controlled to take a picture, and the lighting module is turned off after the picture is taken; the lighting module and the shooting module are integrally arranged and share a light-transmitting window and housing, or the lighting module and the shooting module are separately arranged; It also includes a night light module. When the ambient light is dim and the sensor module senses someone approaching, the night light module turns on. When the sensor module senses that the person has left, the night light module turns off. The night light module is either part of the lighting module or the night light module is set independently of the lighting module.
[0015] By adopting the above technical solution, the external stray light is isolated by automatically closing the top cover or seat ring and the lighting module is turned on to provide stable and uniform internal lighting, creating ideal conditions for shooting without interference from ambient light. This significantly improves the clarity, color reproduction and consistency of the captured dirt images, thereby improving the reliability of subsequent image-based analysis or diagnosis. At the same time, the lighting module can also be used as a night light, or it can be set up independently and cooperate with the night light module.
[0016] Optionally, it also includes an image classification module for classifying the images captured by the shooting module. The image classification module at least identifies the type and / or amount of waste. The image classification module includes a first image classification module installed on the toilet and / or a second image classification module installed on the server. The first image classification module is connected to the main control board. The second image classification module is connected to the main control board through a communication module, and the main control board can receive the classification results of the first image classification module and / or the second image classification module.
[0017] Optionally, the system also includes a flushing system connected to the main control board for performing flushing operations. The main control board can control the flushing system to execute a flushing sequence corresponding to the type of dirt based on the classification results of the image classification module. The flushing system includes at least one brush nozzle. Different flushing sequences correspond to different water outlet times at the brush nozzle. Alternatively, the flushing system includes at least one brush nozzle and one main flushing port, with different flushing sequences corresponding to different water outlet times or water outlet sequences at the brush nozzle.
[0018] By adopting the above technical solution, combining the image classification module with the flushing system, the recorded images are automatically classified and identified. The system can intelligently determine the type and / or amount of dirt, and execute differentiated and precise flushing programs accordingly, achieving intelligent management of water conservation and cleaning. By controlling the different water outlet times at the brush nozzles, targeted flushing can be performed based on the amount of dirt, effectively saving water resources; or by controlling the working sequence of different water outlets, flushing modes for different types of dirt can be flexibly combined, thereby ensuring cleaning effectiveness while achieving precise water use and improving user experience.
[0019] Optionally, the types of waste include at least feces, urine, and toilet paper; the state of feces includes at least loose, normal, and dry. When the waste type is urine, the flushing system performs the first flush. When the type of waste is paper, if the amount of paper is less than a first value, the flushing system performs a first-level flush; if the first value is less than or equal to the amount of paper and less than or equal to a second value, the flushing system performs a second-level flush; if the amount of paper is greater than the second value, the flushing system performs a third-level flush. When the waste type is feces, if the amount of feces is less than a first preset value, the flushing system performs a first-level flush; if the first preset value is less than or equal to the amount of feces and less than or equal to a second preset value, the flushing system performs a second-level flush; if the feces are loose and the amount of feces is greater than the second preset value, the flushing system performs a second flush; if the feces are dry and the amount of feces is greater than the second preset value, the flushing system performs a third-level flush. The flush volume is specified as follows: first flush volume < second flush volume ≤ third flush volume. The second flush refers to a flush that causes the toilet to produce two siphon flushes.
[0020] By adopting the above technical solution, the amount of waste can be identified, and a precise flushing procedure can be executed based on the amount of waste, thus avoiding the waste of water resources.
[0021] Optionally, it also includes a server and a communication module. The main control board is connected to the server through the communication module. The main control board can upload the images captured by the shooting module and related data to the server. The second image classification module is used to classify the images captured by the shooting module under the corresponding device and store them on the server.
[0022] By adopting the above technical solution, the waste record data can be transferred from local to cloud, and the images can be uploaded to the server to utilize more powerful computing power for accurate classification and long-term storage.
[0023] Optionally, it also includes a large model analysis system, which is connected to the server via a data interface; the large model analysis system receives at least one image and / or text records associated with the image, analyzes the received image and / or text records, and generates a corresponding analysis report.
[0024] By adopting the above technical solutions, the large model analysis system performs in-depth analysis on automatically recorded dirt images, generates analysis reports, and transforms the raw image data into information that is easier for users and doctors to understand. This greatly enhances the added value of the records, assists users in conducting health self-tests, and provides doctors with a more comprehensive reference for diagnosis.
[0025] Optionally, it also includes a mobile terminal connected to the toilet, which allows users to view all public photos stored on the corresponding device; or, to copy photos to the corresponding personal account on the mobile terminal for storage and categorized management, facilitating user access; the shooting module establishes a connection with the mobile terminal via a communication module; the main control board transmits image data captured by the shooting module directly to the mobile terminal for local storage via the communication module; the mobile terminal uploads the locally stored image data to the server via an application, or the shooting module communicates with the server via the communication module, and the mobile terminal connects to the server via the communication module.
[0026] By adopting the above technical solution, image data is directly transmitted to the local storage of the mobile terminal, ensuring that data is not lost when the network is poor, making it convenient for users to view at any time, and improving the security of privacy data. Users can decide to synchronize data to the cloud server through the application, or the shooting module can communicate with the server through the communication module, and the mobile terminal can connect to the server through the communication module, realizing the convenience and controllability of data management and improving the data flow scheme of the overall system.
[0027] In summary, this application includes the following beneficial technical effects: 1. By setting up a linkage control mechanism between the sensing module, the shooting module and the main control board, it can automatically trigger the acquisition and recording of images of waste after the user uses the toilet, realizing objective and imperceptible recording of waste images.

[0031] The following is in conjunction with the appendix Figure 1-9 This application will be described in further detail.
[0032] This application discloses an automatic waste recording system for a smart toilet. (Refer to...) Figure 1 and Figure 2The automatic waste recording system of the smart toilet includes a toilet body 1, a base 2, a main control board 3, a sensor module, and a camera module 5. The sensor module senses the user's usage status and sends a shooting command to the main control board 3 based on the usage status. The camera module 5 is mounted on the base 2 or the toilet body 1, with the shooting direction facing the water cover area inside the toilet body 1. The main control board 3 is electrically connected to the sensor module and the camera module 5. After receiving the shooting command from the sensor module, the main control board 3 controls the camera module 5 to immediately or after a delay to capture images of the water cover area and generate images. By setting up a linkage control mechanism between the sensor module, the camera module 5, and the main control board 3, the system can automatically trigger the acquisition and recording of waste images after the user uses the toilet, achieving objective and imperceptible waste image recording. This fundamentally solves the problems of inconvenience, data loss, and inaccuracy caused by relying on manual operation and subjective memory, providing intuitive and reliable objective evidence for clinical diagnosis.
[0033] In some embodiments, the coverage area of the shooting module 5 is greater than or equal to the area of the water cover area, and a single shooting command continuously takes pictures to obtain at least two photos, preferably at least three photos. An image storage device is also provided for storing images and storing data containing at least the shooting time and shooting device information. The image storage device is located on the toilet or on a server. When the number of images stored in the image storage device exceeds a preset threshold, the oldest image data is automatically deleted or replaced, ensuring that the dirt image is captured completely and clearly, improving the success rate of recording and image quality. Simultaneously, due to cost reasons, local storage space is limited, and only the most recent images can be saved. This facilitates querying the most recent records in special circumstances and prevents the need to query records and take correct action after emergencies (power outages or data interruptions), ensuring that the system can operate stably for a long time and retain the most recent valid records.
[0034] In some embodiments, the sensing module is a seat sensor installed in the toilet seat 11, used to detect the user's sitting and / or getting up actions, and to generate and issue a shooting command when a getting up signal or a set of signals of sitting up and then getting up is detected; Alternatively, the sensing module may be a microwave sensing module 4 installed inside the toilet shell 7. The sensing module is used to detect whether a user enters and / or leaves the toilet area, and / or, the sensing module is used to detect whether there is a person in the toilet area, and generates and issues a shooting command after detecting that the user has left the toilet area, or generates and issues a shooting command if the user enters the toilet area and then leaves the toilet area, or generates and issues a shooting command if the user enters the toilet area, stays in the toilet area for a preset time and then leaves the toilet area. Alternatively, the sensing module may include a seating sensor disposed within the toilet seat 11 and a microwave sensing module 4 disposed within the toilet shell 7. The seating sensor detects the user's sitting and / or getting up actions, and the microwave sensing module 4 detects whether the user enters and / or leaves the toilet area, and / or detects whether there is a person within the toilet area. Upon detecting an getting up signal by the seating sensor and the user leaving the toilet area by the microwave sensing module 4, a recording command is generated and issued. This allows for accurate and seamless determination of the user's completion of use, automatically triggering recording at the optimal time.
[0035] Reference Figure 8 and Figure 9 In some embodiments, the shooting module 5 includes a housing 53, a light-transmitting window 52, and a camera 51. The light-transmitting window 52 is a transparent structure, integrally or separately set with the housing 53, and sealed and fixedly connected, forming a sealed inner cavity together with the housing 53. The camera 51 is set in the inner cavity, with its lens facing the light-transmitting window 52, so that the camera 51 can be better protected. It also includes a second driving device 6, which is connected to the shooting module 5 and is used to drive the shooting module 5 to perform telescopic movement. After the main control board 3 receives the shooting command from the sensing module, the second driving device 6 drives the shooting module 5 to extend into the toilet bowl to take a picture. After the picture is taken, the shooting module 5 retracts to the initial state. The shooting module 5 is set in the body 12 carrying the sealing cover 13. When the shooting module 5 extends, the sealing cover 13 opens. When the shooting module 5 retracts, the sealing cover 13 closes to form a sealed inner cavity. The second driving device 6 can be a gear set, and a rack that meshes with the gear set can be provided on the housing 53. This gear set drives the shooting module 5 to move. When shooting is needed, the shooting module 5 can be moved and extended into the toilet for a better shooting angle. The shooting module 5 is housed inside the body 12, which carries the sealing cover 13. The sealing cover 13 better protects the shooting module 5 and prevents it from being contaminated by the environment.
[0036] Reference Figure 2 and Figure 3In some embodiments, the device further includes a drive unit 8 and a lighting module 9. The drive unit 8 is connected to the main control board 3 and is used to drive the toilet lid 10 and / or seat ring 11 to open and close. The lighting module 9 is disposed on the base 2 and connected to the main control board 3. After receiving the shooting command from the sensing module, the main control board 3 controls the drive unit 8 to immediately or after a delay close the lid 10 and / or the seat ring 11 and simultaneously turn on the lighting module 9; or, after closing the lid 10 and / or the seat ring 11, the lighting module 9 is turned on, and then the shooting module 5 is controlled to take a picture. After the picture is taken, the lighting module 9 is turned off. The lighting module 9 and the shooting module 5 are integrally disposed and share a light-transmitting window 52 and a housing 53, or the lighting module 9 and the shooting module 5 are separately disposed. It also includes a night light module. When the ambient light is dim and the sensor module detects someone approaching, the night light module turns on. When the sensor module detects that the person has left, the night light module turns off. The night light module is either part of the lighting module 9 or it can be set independently of the lighting module 9. The lighting module 9 provides a stable and uniform internal light source, resulting in clearer and more reliable image capture.

The image classification module at least identifies the type and / or amount of dirt. The image classification module includes a first image classification module installed on the toilet and / or a second image classification module installed on the server. The first image classification module is connected to the main control board 3. The second image classification module is connected to the main control board 3 through a communication module. The main control board 3 can receive the classification results of the first image classification module and / or the second image classification module.
[0038] Reference Figure 5 and Figure 6 In some embodiments, a flushing system is also included, which is connected to the main control board 3 and is used to perform flushing operations. The main control board 3 can control the flushing system to perform flushing sequences corresponding to the type of dirt according to the classification results of the image classification module. The flushing system includes at least one brush nozzle. Different flushing sequences correspond to different water outlet times of the brush nozzle. Alternatively, the flushing system includes at least one brush nozzle and one main flushing port, and different flushing sequences correspond to different water outlet times or water outlet sequences of the brush nozzle.
[0039] Reference Figure 4 In some embodiments, the types of waste include at least feces, urine, and paper towels; the state of feces includes at least loose, normal, and dry. When the waste type is urine, the flushing system performs the first flush (small flush). When the type of contaminant is paper, if the amount of paper is less than the first value (i.e., when there is little paper), the flushing system performs the first flush (small flush); if the first value is less than or equal to the amount of paper and less than or equal to the second value (i.e., when the amount of paper is normal), the flushing system performs the second flush (large flush); if the amount of paper is greater than the second value (i.e., when there is a lot of paper), the flushing system performs the third flush (large flush with extended flushing time). The first and second values can be set according to the program.
[0040] When the waste type is feces, if the amount of feces is less than the first preset value (i.e., a small amount of feces), the flushing system executes the first flush (small flush); if the first preset value is less than or equal to the amount of feces and less than or equal to the second preset value (i.e., normal amount of feces), the flushing system executes the second flush (large flush); if the feces are loose and the amount of feces is greater than the second preset value (i.e., loose and plentiful feces), the flushing system executes a second flush, which creates two siphon flushes in the toilet bowl. Specifically, the second flush involves flushing the toilet bowl in the following sequence: brush rim, main flush, brush rim, main flush, and brush rim again; if the feces are dry and the amount of feces is greater than the second preset value (i.e., dry and plentiful feces), the flushing system executes the third flush (large flush with extended flushing time). If no foreign objects are detected, no flushing is performed.
[0041] Reference Figure 7 In other embodiments, a server and a communication module are also included. The main control board 3 is connected to the server via the communication module. The main control board 3 can upload images and associated data captured by the shooting module 5 to the server. The associated data includes shooting time, shooting device, etc. The second image classification module is used to classify the images captured by the shooting module 5 under the corresponding device and store them on the server. The second image classification module at least identifies the type of waste, which is divided into feces, urine, and other.
[0042] In some embodiments, a large model analysis system is also included, which is connected to the server via a data interface; the large model analysis system receives at least one image and / or text records associated with the image, analyzes the received image and / or text records, generates a corresponding analysis report, and sends the analysis report to a mobile terminal for display.
[0043] In some embodiments, a mobile terminal is also included, which is connected to the toilet. The mobile terminal allows users to view all public photos stored on the corresponding device; or, the mobile terminal allows users to copy photos to their corresponding personal account for storage and categorized management, facilitating user access. The shooting module 5 establishes a connection with the mobile terminal via a communication module. The main control board 3 transmits the image data captured by the shooting module 5 directly to the mobile terminal for local storage via the communication module. The mobile terminal uploads the locally stored image data to the server via an application, or the shooting module 5 communicates with the server via the communication module, and the mobile terminal connects to the server via the communication module.
