Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of intelligent bathroom technology, and in particular to an intelligent toilet and a flushing control method thereof. Background Art
[0002] With the rapid development of smart home technology, smart toilets, a key component in the modern bathroom sector, have become increasingly popular and mainstream. These toilets typically feature automatic flushing, heated seats, and warm air drying, aiming to enhance user comfort and hygiene.
[0003] In recent years, some high-end smart toilets have begun to try to introduce sensor flushing technology, such as using infrared or ultrasonic sensors to detect when the user leaves and automatically trigger the flush, so as to reduce contact pollution caused by manual operation.
[0004] However, existing smart toilets still lack intelligence in flushing control, especially in sewage volume identification and water-saving optimization, where there is still much room for improvement.
[0005] BACKGROUND OF THE INVENTION The above information disclosed is only for understanding the background of the concept of the application and may contain information that does not constitute the prior art. Summary of the Invention
[0006] Based on this, it is necessary to provide a smart toilet and a flushing control method thereof to address the above problems.
[0007] The present application provides a flushing control method for an intelligent toilet, which comprises the following steps:
[0008] Detect environmental changes in the toilet bowl through optical sensors;
[0009] determining the amount of sewage discharged according to environmental changes in the toilet bowl;
[0010] Controlling the smart toilet to flush the toilet bowl according to the sewage discharge volume;
[0011] If it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume, controlling the smart toilet to perform a first flushing mode;
[0012] If it is determined that the sewage discharge volume is less than the preset sewage discharge volume, the smart toilet is controlled to enter the second flushing mode, and the flushing volume of the second flushing mode is less than the flushing volume of the first flushing mode.
[0013] The above-mentioned intelligent toilet flushing control method can achieve at least the following beneficial effects:
[0014] By using optical sensors to detect changes in the toilet bowl environment in real time, it can accurately distinguish the amount of waste discharged, such as the amount of kitchen waste dumped by the user, or the amount of waste discharged from the user's feces and urine, and automatically match the corresponding flushing mode according to the different waste discharge volumes. When the waste discharge volume is greater than or equal to the preset waste discharge volume (such as during defecation), the first flushing mode with a larger water volume is used to ensure thorough cleaning. When the waste discharge volume is less than the preset waste discharge volume (such as during urination), the second flushing mode with a smaller water volume is used to achieve a water-saving effect. This method not only improves the intelligence and accuracy of flushing control, but also effectively avoids the water waste caused by the single flushing mode of traditional toilets. At the same time, it ensures hygiene through non-contact detection, providing users with a more intelligent, environmentally friendly and comfortable toilet experience.
[0015] In some embodiments, the step of detecting environmental changes in the toilet bowl by an optical sensor includes:
[0016] When a foreign object is detected to have fallen into the toilet bowl, an optical sensor is used to detect the fluctuation amplitude of the water surface in the toilet bowl;
[0017] The step of determining the sewage discharge amount according to the environmental changes in the toilet bowl includes:
[0018] When the fluctuation amplitude of the water surface is greater than or equal to the preset fluctuation amplitude, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When the fluctuation amplitude of the water surface is less than the preset fluctuation amplitude, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0019] An optical sensor is used to detect the fluctuation amplitude of the water surface cover in the toilet bowl. When the fluctuation amplitude is greater than or equal to the preset fluctuation amplitude, it is judged that the sewage discharge volume is greater than or equal to the preset sewage discharge volume and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the fluctuation amplitude is less than the preset fluctuation amplitude, it is judged that the sewage discharge volume is less than the preset sewage discharge volume and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is started. This achieves accurate identification of the sewage discharge volume based on the fluctuation amplitude of the water surface, thereby triggering different flushing modes accordingly, which not only ensures the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as during defecation), but also achieves the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as during urination), thereby improving the degree of automation and user experience of the smart toilet.
[0020] In some embodiments, the step of detecting environmental changes in the toilet bowl by an optical sensor includes:
[0021] When a foreign object is detected to have fallen into the toilet bowl, an optical sensor is used to detect the rise in the water level in the toilet bowl;
[0022] The step of determining the sewage discharge amount according to the environmental changes in the toilet bowl includes:
[0023] When the water level rise is greater than or equal to the preset rise, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount; when the water level rise is less than the preset rise, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0024] An optical sensor is used to monitor in real time the water level rise caused by foreign objects falling into the toilet bowl. When it is detected that the water level rise exceeds a preset threshold, it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the water level rise is lower than the threshold, it is determined that the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is started. This realizes intelligent identification of sewage discharge volume and differentiated flushing control based on water level change characteristics, effectively improving water resource utilization efficiency while ensuring hygienic cleaning effects. It not only ensures the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating), but also realizes the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), thereby improving the automation level and user experience of the smart toilet.
[0025] In some embodiments, the step of detecting environmental changes in the toilet bowl by an optical sensor includes:
[0026] When a foreign object is detected to have fallen into the toilet bowl, an optical sensor is used to detect whether the foreign object is stuck on the inner wall of the toilet bowl;
[0027] The step of determining the sewage discharge amount according to the environmental changes in the toilet bowl includes:
[0028] When there is foreign matter stuck on the inner wall of the toilet bowl, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When there is no foreign matter stuck on the inner wall of the toilet bowl, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0029] An optical sensor is used to monitor the attachment of foreign matter to the inner wall of the toilet bowl in real time. When foreign matter is detected adhering to the inner wall, it is determined that the discharge volume is greater than or equal to the preset discharge volume (such as when defecating) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When no foreign matter is detected adhering to the inner wall, it is determined that the discharge volume is less than the preset discharge volume (such as when urinating) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is activated. This realizes intelligent identification of discharge volume and differentiated flushing control based on the detection of inner wall attachments, effectively improving the utilization efficiency of water resources while ensuring hygienic cleaning effects. It not only ensures the cleaning effect when the discharge volume is greater than or equal to the preset discharge volume (such as when defecating), but also realizes the water-saving function when the discharge volume is less than the preset discharge volume (such as when urinating), thereby improving the automation level and user experience of the smart toilet.
[0030] In some embodiments, the step of detecting environmental changes in the toilet bowl by an optical sensor includes:
[0031] When a foreign object is detected to have fallen into the toilet bowl, an optical sensor is used to detect whether the foreign object is protruding from the water cover of the toilet bowl;
[0032] The step of determining the sewage discharge amount according to the environmental changes in the toilet bowl includes:
[0033] When there is foreign matter protruding from the water cover of the toilet bowl, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When there is no foreign matter protruding from the water cover of the toilet bowl, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0034] An optical sensor is used to monitor the status of the toilet bowl water cover in real time. When a foreign object is detected protruding from the water cover, it is automatically determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the water cover remains flat and no foreign object is protruding, it is determined that the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is activated. This realizes intelligent identification of sewage discharge volume and differentiated flushing control based on foreign object detection on the water cover, and utilizes the non-contact detection characteristics of the optical sensor to accurately distinguish between defecation and urination behaviors, optimizing water resource utilization efficiency while ensuring hygienic cleaning effects. It not only ensures the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating), but also realizes the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), thereby improving the automation level and user experience of the smart toilet.
[0035] In some embodiments, the seat of the smart toilet has a seat sensing function;
[0036] Before the step of controlling the intelligent toilet to flush the toilet bowl according to the sewage discharge volume, the method further includes the following steps:
[0037] Detecting whether the user sits on the seat;
[0038] If the user has not sat on the seat before, proceed to the next step;
[0039] If the user has sat on the seat before, the next step is performed after the user leaves the seat.
[0040] If the system detects a user sitting down, it delays the flush until they've completely left their seat. This prevents the discomfort caused by splashing water when flushing while seated, and significantly reduces the risk of aerosol contamination during the flushing process. Through this intelligent judgment based on the user's actual usage status, the system ensures maximum user hygiene and safety, preventing the spread of bacteria and viruses through aerosols, while ensuring effective flushing.
[0041] In some embodiments, the seat of the smart toilet has a seat sensing function;
[0042] Before the step of detecting environmental changes in the toilet bowl by an optical sensor, the method further includes:
[0043] Detecting whether the user sits on the seat;
[0044] Before the step of controlling the intelligent toilet to flush the toilet bowl according to the sewage discharge volume, the method further includes the following steps:
[0045] If it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume, the spray gun of the smart toilet is controlled to clean the user's buttocks.
[0046] After confirming the user's seated status through seat sensing, the optical sensor activates real-time monitoring of the toilet bowl environment to ensure accurate detection timing. If the system determines that the discharge volume is greater than or equal to the preset discharge volume (such as during defecation), the spray gun is controlled to perform a buttocks cleansing operation before flushing. This sequential control design aligns with optimal human hygiene procedures. By intelligently linking discharge volume identification, spray gun cleaning, and flushing operations, this solution achieves a fully automated "identify-clean-flush" process, improving cleaning efficiency and optimizing the user experience. Furthermore, this phased processing mechanism effectively prevents potential cross-contamination during the cleaning process, ensuring reliable hygienic operation.
[0047] In some embodiments, before the step of controlling the spray gun of the smart toilet to clean the user's buttocks if it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount, the following steps are also included:
[0048] If the user has sat on the seat, the optical sensor detects the user's genitals to determine the user's gender;
[0049] If it is determined that the sewage discharge volume is less than the preset sewage discharge volume and the user is female, the spray gun of the smart toilet is controlled to clean the user's genitals.
[0050] By combining seat sensing with optical sensor detection, the smart toilet first identifies the user's gender after they sit down. If the user is identified as female and the discharge volume is less than a preset volume (such as during urination), a genital cleansing program tailored to female sexual characteristics is automatically initiated. This gender-adaptive design takes into account the female urethra's shorter and more susceptible to infection. A gentle flush immediately after urination is more effective in preventing urinary tract infections than traditional paper towel wiping. Non-optical sensor detection technology ensures accurate gender recognition and mitigates the risk of privacy leaks from cameras. The system automatically adjusts the spray gun's water outlet angle and flow pattern based on gender. The female mode uses a softer, fan-shaped water flow with antibacterial ingredients. The entire operation process strictly follows intelligent timing control from seat detection to gender recognition, followed by discharge monitoring and finally targeted cleaning, ensuring precise connection between each step. This not only addresses the problem of existing smart toilets not taking the needs of female users into consideration, but also avoids false triggering or blind spots in cleaning. By organically combining biometric recognition technology with cleaning strategies, a personalized hygiene and cleaning solution truly meets the physiological needs of different genders is achieved.
[0051] In some embodiments, after the step of detecting the user's genitals by an optical sensor to determine the user's gender if the user has sat on the seat, the following step is also included:
[0052] Detecting the user's hip and genital changes through optical sensors;
[0053] If the hip change value is greater than the first change value, it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount;
[0054] If the vaginal change value is greater than the second change value, it is determined that the sewage discharge amount is less than the preset sewage discharge amount.
[0055] Optical sensors are used to quantify the dynamic changes in the user's buttocks and genitals, enabling accurate identification and classification of waste discharge. After completing gender recognition, the system continuously monitors the deformation characteristics of the user's relevant parts, and by setting a dual-parameter comparison mechanism of hip change thresholds and genital change thresholds, a waste discharge discrimination model based on biomechanical characteristics is constructed. When it is detected that the displacement of the hip area exceeds a preset first threshold, the waste discharge is greater than or equal to the preset waste discharge (such as during defecation), and when the activity amplitude of the genital area exceeds a second threshold, the waste discharge is less than the preset waste discharge (such as during urination). The system has designed a dynamic calibration algorithm for genital changes specifically for female users, which can automatically optimize the judgment threshold according to individual physiological differences, ensuring that users of different body shapes can obtain accurate detection results.
[0056] The present application also provides a smart toilet, which is based on the flushing control method of the smart toilet described in any of the above embodiments, and the smart toilet includes an optical sensor, a toilet seat with a toilet bowl, and a smart toilet cover provided on the toilet seat.
[0057] The above-mentioned smart toilet has at least the following beneficial effects:
[0058] This smart toilet can detect environmental changes in the toilet bowl in real time through optical sensors, accurately distinguishing the amount of waste discharged, such as the amount of kitchen waste dumped by the user, or the amount of feces and urine discharged by the user, and automatically matching the corresponding flushing mode according to the different waste discharge volumes. When the waste discharge volume is greater than or equal to the preset waste discharge volume (such as during defecation), a first flushing mode with a larger water volume is used to ensure thorough cleaning. When the waste discharge volume is less than the preset waste discharge volume (such as during urination), a second flushing mode with a smaller water volume is used to achieve a water-saving effect. This method not only improves the intelligence and accuracy of flushing control, but also effectively avoids the water waste caused by the single flushing mode of traditional toilets. At the same time, it ensures hygiene through non-contact detection, providing users with a more intelligent, environmentally friendly and comfortable toilet experience.

However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0069] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 In some embodiments, the present application provides a flushing control method for a smart toilet 10, which includes the following steps:
[0070] S10: Detecting environmental changes in the toilet bowl 110 through the optical sensor 300;
[0071] S20: Determine the sewage discharge amount according to the environmental changes in the toilet 110;
[0072] S30: controlling the smart toilet 10 to flush the toilet bowl 110 according to the sewage discharge volume;
[0073] S40: If it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume, controlling the smart toilet 10 to perform the first flushing mode;
[0074] S50: If it is determined that the sewage discharge volume is less than the preset sewage discharge volume, the smart toilet 10 is controlled to enter the second flushing mode, and the flushing volume of the second flushing mode is less than the flushing volume of the first flushing mode.
[0075] The flushing control method of the smart toilet 10 can achieve at least the following beneficial effects:
[0076] By detecting the environmental changes in the toilet bowl 110 in real time through the optical sensor 300, it is possible to accurately distinguish the amount of sewage discharge, such as the amount of kitchen waste dumped by the user, or the amount of feces and urine discharged by the user, and automatically match the corresponding flushing mode according to the different sewage discharge amounts. The optical sensor 300 may include but is not limited to laser radar, etc. Figure 4 As shown, when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as defecation), the first flushing mode with a larger water volume is used to ensure thorough cleaning, such as Figure 3 As shown, when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), a second flushing mode with a smaller water volume is used to achieve water-saving effect. This method not only improves the intelligence and accuracy of flushing control, but also effectively avoids the waste of water resources caused by the single flushing mode of traditional toilets. At the same time, it ensures hygiene through non-contact detection, providing users with a more intelligent, environmentally friendly and comfortable toilet experience.
[0077] In some embodiments, the step S10 of detecting environmental changes in the toilet bowl 110 using the optical sensor 300 includes:
[0078] When a foreign object is detected to have fallen into the toilet bowl 110, the optical sensor 300 detects the fluctuation amplitude of the water cover 400 in the toilet bowl 110;
[0079] The step S20 of determining the sewage discharge amount according to the environmental changes in the toilet bowl 110 includes:
[0080] When the fluctuation amplitude of the water cover 400 is greater than or equal to the preset fluctuation amplitude, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When the fluctuation amplitude of the water cover 400 is less than the preset fluctuation amplitude, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0081] The optical sensor 300 is used to detect the fluctuation amplitude of the water surface cover 400 in the toilet bowl 110. When the fluctuation amplitude is greater than or equal to the preset fluctuation amplitude, it is judged that the sewage discharge volume is greater than or equal to the preset sewage discharge volume and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the fluctuation amplitude is less than the preset fluctuation amplitude, it is judged that the sewage discharge volume is less than the preset sewage discharge volume and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is started. This achieves accurate identification of the sewage discharge volume based on the fluctuation amplitude of the water surface cover 400, thereby triggering different flushing modes accordingly, ensuring the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as during defecation), and achieving the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as during urination), thereby improving the degree of automation and user experience of the smart toilet 10.
[0082] In some embodiments, the step S10 of detecting environmental changes in the toilet bowl 110 using the optical sensor 300 includes:
[0083] When a foreign object is detected to have fallen into the toilet bowl 110, the optical sensor 300 detects the rise of the water level in the toilet bowl 110;
[0084] The step S20 of determining the sewage discharge amount according to the environmental changes in the toilet bowl 110 includes:
[0085] When the water level rise is greater than or equal to the preset rise, it is judged that the sewage discharge amount is greater than or equal to the preset sewage discharge amount; when the water level rise is less than the preset rise, it is judged that the sewage discharge amount is less than the preset sewage discharge amount.
[0086] The optical sensor 300 monitors in real time the water level rise caused by foreign matter (such as urine, feces, kitchen waste, etc.) falling into the toilet bowl 110. When it is detected that the water level rise exceeds a preset threshold, it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as during defecation) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the water level rise is lower than the threshold, it is determined that the sewage discharge volume is less than the preset sewage discharge volume (such as during urination) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is activated. This realizes intelligent identification of sewage discharge volume and differentiated flushing control based on water level change characteristics, effectively improving water resource utilization efficiency while ensuring hygienic cleaning effects. It not only ensures the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as during defecation), but also realizes the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as during urination), thereby improving the automation level and user experience of the smart toilet 10.
[0087] In some embodiments, the step S10 of detecting environmental changes in the toilet bowl 110 using the optical sensor 300 includes:
[0088] When it is detected that a foreign object has fallen into the toilet bowl 110, the optical sensor 300 detects whether the foreign object is stuck on the inner wall of the toilet bowl 110;
[0089] The step S20 of determining the sewage discharge amount according to the environmental changes in the toilet bowl 110 includes:
[0090] When there is foreign matter stuck on the inner wall of the toilet bowl 110 , it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When there is no foreign matter stuck on the inner wall of the toilet bowl 110 , it is determined that the sewage discharge amount is less than the preset sewage discharge amount.
[0091] The optical sensor 300 monitors the foreign matter adhesion on the inner wall of the toilet bowl 110 in real time. When foreign matter is detected adhering to the inner wall, it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When no foreign matter is detected adhering to the inner wall, it is determined that the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is activated. This realizes intelligent identification of sewage discharge volume and differentiated flushing control based on the detection of inner wall attachments, effectively improving the efficiency of water resource utilization while ensuring sanitary cleaning effects. It not only ensures the cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating), but also realizes the water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), thereby improving the degree of automation and user experience of the smart toilet 10.
[0092] In some embodiments, the step S10 of detecting environmental changes in the toilet bowl 110 using the optical sensor 300 includes:
[0093] When it is detected that a foreign object has fallen into the toilet bowl 110, the optical sensor 300 detects whether the foreign object protrudes from the water cover 400 of the toilet bowl 110;
[0094] The step S20 of determining the sewage discharge amount according to the environmental changes in the toilet bowl 110 includes:
[0095] When there is foreign matter protruding from the water cover 400 of the toilet bowl 110 , it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount. When there is no foreign matter protruding from the water cover 400 of the toilet bowl 110 , it is determined that the sewage discharge amount is less than the preset sewage discharge amount.
[0096] The optical sensor 300 monitors the status of the water cover 400 of the toilet bowl 110 in real time. When it is detected that a foreign object protrudes from the water cover 400, it is automatically determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating) and the first flushing mode (i.e., a strong flushing mode with a larger water volume) is triggered. When the water cover 400 remains flat and no foreign object protrudes, it is determined that the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating) and the second flushing mode (i.e., a water-saving flushing mode with a smaller water volume) is activated. Intelligent identification of sewage discharge volume and differentiated flushing control based on foreign object detection on the water cover 400 are realized, and the non-contact detection characteristics of the optical sensor 300 are used to accurately distinguish between defecation and urination behaviors, optimizing water resource utilization efficiency while ensuring hygienic cleaning effects, ensuring a cleaning effect when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as when defecating), and realizing a water-saving function when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), thereby improving the degree of automation and user experience of the smart toilet 10.
[0097] In some embodiments, the seat 230 of the smart toilet 10 has a seat sensing function;
[0098] Before step S30 of controlling the intelligent toilet 10 to flush the toilet bowl 110 according to the sewage discharge volume, the following steps are also included:
[0099] Detecting whether the user sits on the seat 230;
[0100] If the user has not sat on the seat 230 before, proceed to the next step;
[0101] If the user has sat on the seat 230 before, the next step is performed after the user leaves the seat.
[0102] If the system detects a user sitting down, it delays the flush until they've completely left their seat. This prevents the discomfort caused by splashing water when flushing while seated, and significantly reduces the risk of aerosol contamination during the flushing process. Through this intelligent judgment based on the user's actual usage status, the system ensures maximum user hygiene and safety, preventing the spread of bacteria and viruses through aerosols, while ensuring effective flushing.
[0103] In some embodiments, the seat 230 of the smart toilet 10 has a seat sensing function;
[0104] Before the step S10 of detecting the environmental changes in the toilet bowl 110 by the optical sensor 300, the method further includes:
[0105] Detecting whether the user sits on the seat 230;
[0106] Before step S30 of controlling the intelligent toilet 10 to flush the toilet bowl 110 according to the sewage discharge volume, the following steps are also included:
[0107] If it is determined that the sewage discharge volume is greater than or equal to the preset sewage discharge volume, the spray gun of the smart toilet 10 is controlled to clean the user's buttocks.
[0108] After the seat 230 senses and confirms the user's seated status, the optical sensor 300 is activated to monitor the toilet bowl 110 environment in real time, ensuring accurate detection timing. If the system determines that the discharge volume is greater than or equal to the preset discharge volume (such as during defecation), the spray gun is controlled to perform a buttocks cleansing operation before flushing. This sequential control design aligns with optimal human hygiene procedures. By intelligently linking discharge volume identification, spray gun cleaning, and flushing operations, this solution achieves a fully automated "identify-clean-flush" process, improving cleaning efficiency and optimizing the user experience. Furthermore, this phased processing mechanism effectively prevents potential cross-contamination during the cleaning process, ensuring reliable hygienic operation.
[0109] In some embodiments, before the step of controlling the spray gun of the smart toilet 10 to clean the user's buttocks if it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount, the following steps are also included:
[0110] If the user has sat on the seat 230, the optical sensor 300 detects the user's genitals to determine the user's gender;
[0111] If it is determined that the sewage discharge volume is less than the preset sewage discharge volume and the user is female, the spray gun of the smart toilet 10 is controlled to clean the user's genitals.
[0112] By combining the seat sensing of the seat ring 230 of the smart toilet 10 with the detection of the optical sensor 300, gender recognition is first performed after the user sits down. When it is determined that the user is a female user and the sewage discharge volume is less than the preset sewage discharge volume (such as urination), the genital cleaning program tailored to the female physiological characteristics is automatically started. This gender-adaptive design fully considers the physiological characteristics of the female urethra being shorter and more susceptible to infection, and performs a gentle flush immediately after urination, which is more effective in preventing urinary tract infections than traditional paper towel wiping. At the same time, the non-optical optical sensor 300 detection technology is used to ensure the accuracy of gender recognition, avoiding To avoid the risk of privacy leakage from the camera, the system automatically adjusts the water outlet angle and water flow pattern of the spray gun according to gender. The female mode adopts a softer fan-shaped water flow and adds antibacterial ingredients. The entire operation process strictly follows the intelligent timing control from seat detection to gender recognition, excretion monitoring and finally targeted cleaning to ensure the precise connection of each link. It not only solves the problem that existing smart toilets do not consider the needs of female users enough, but also avoids false triggering or cleaning blind spots. Through the organic combination of biometric recognition technology and cleaning strategies, a personalized hygiene and cleaning plan that truly meets the physiological needs of different genders is achieved.
[0113] In some embodiments, after the step of detecting the user's genitals by the optical sensor 300 to determine the user's gender if the user has sat on the seat 230, the following steps are further included:
[0114] Detecting the user's hip and genital changes through the optical sensor 300;
[0115] If the hip change value is greater than the first change value, it is determined that the sewage discharge amount is greater than or equal to the preset sewage discharge amount;
[0116] If the vaginal change value is greater than the second change value, it is determined that the sewage discharge amount is less than the preset sewage discharge amount.
[0117] The optical sensor 300 quantifies the dynamic changes in the user's buttocks and genitals, achieving accurate identification and classification of waste discharge. After completing gender recognition, the system continuously monitors the deformation characteristics of the relevant parts of the user. By setting a dual-parameter comparison mechanism of hip change thresholds and genital change thresholds, a waste discharge discrimination model based on biomechanical characteristics is constructed. When the displacement of the hip area is detected to exceed a preset first threshold, the waste discharge is greater than or equal to the preset waste discharge (such as during defecation), and when the activity amplitude of the genital area exceeds a second threshold, the waste discharge is less than the preset waste discharge (such as during urination). The system has designed a dynamic calibration algorithm for genital changes specifically for female users, which can automatically optimize the judgment threshold according to individual physiological differences, ensuring that users of different body shapes can obtain accurate detection results.
[0118] In addition, if Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6 As shown, the present application also provides a smart toilet 10, which is based on the flushing control method of the smart toilet 10 described in any of the above embodiments, wherein the smart toilet 10 includes an optical sensor 300, a toilet seat 100 provided with a urinal 110, and a smart toilet cover 200 provided on the toilet seat 100, wherein the smart toilet cover 200 includes a movement base 210 provided on the toilet seat 100, a flip cover 220 rotatably connected to the movement base 210, and a seat ring 230. The number of the optical sensor 300 is at least one, that is, the number of the optical sensor 300 can be one or more; the optical sensor 300 can be provided on at least one of the components such as the toilet seat 100, the movement base 210, the seat ring 230, and the flip cover 220; the optical sensor 300 can also be external, that is, it is not connected to the smart toilet cover 200 or the toilet seat 100.
[0119] The above-mentioned smart toilet 10 has at least the following beneficial effects:
[0120] The smart toilet 10 can detect the environmental changes in the toilet bowl 110 in real time through the optical sensor 300, and can accurately distinguish the amount of sewage discharged, such as the amount of kitchen waste dumped by the user, or the amount of sewage discharged by the user's feces and urine, and automatically match the corresponding flushing mode according to the different sewage discharge amounts. The optical sensor 300 may include but is not limited to laser radar, etc. Figure 4 As shown, when the sewage discharge volume is greater than or equal to the preset sewage discharge volume (such as defecation), the first flushing mode with a larger water volume is used to ensure thorough cleaning, such as Figure 3As shown, when the sewage discharge volume is less than the preset sewage discharge volume (such as when urinating), a second flushing mode with a smaller water volume is used to achieve water-saving effect. This method not only improves the intelligence and accuracy of flushing control, but also effectively avoids the waste of water resources caused by the single flushing mode of traditional toilets. At the same time, it ensures hygiene through non-contact detection, providing users with a more intelligent, environmentally friendly and comfortable toilet experience.
