Abstract
Description
Technical Field
[0001] This invention relates to the field of smart home appliance technology, and in particular to a smart toilet flushing control method, a smart toilet seat, and a smart toilet. Background Technology
[0002] Currently, there are three main ways to trigger the flushing action of smart toilets. One method uses a seat sensor to identify sitting and getting up, and combines this with the sitting time to initiate the flushing action. This method can only detect sitting and cannot provide a quick flush for men. Another method involves adding a foot sensor to detect foot kicks and trigger the flushing action. This method is more expensive and requires additional user operation. The third method uses traditional methods such as buttons on the main unit or a remote control to trigger the flushing action, which is inconvenient for users. In addition, some low-end or low-power models use infrared human body detection to achieve low-power automatic flushing control, but this is prone to accidental flushing during opening or closing of the lid. Summary of the Invention
[0003] This invention provides a smart toilet flushing control method, a smart toilet seat, and a smart toilet, which achieves automatic flushing control at low cost, more accurately identifies user usage scenarios, and avoids accidental touches caused by actions such as opening the lid.
[0004] In a first aspect, embodiments of the present invention provide a smart toilet flushing control method, the method comprising: Distance information is collected in real time by a TOF detection module placed in the electronic seat of the smart toilet. The distance information is matched with the preset distance information of the cover plate and seat ring movement trajectory to determine the opening and closing status of the cover plate and seat ring; The distance information is compared with a preset human body distance range to determine the user scenario based on the comparison result and the switch status of the cover plate and seat ring, and to perform large and small punching actions according to the user scenario.
[0005] Optionally, matching the distance information with the preset distance information of the cover plate and seat ring movement trajectory to determine the opening and closing state of the cover plate and seat ring includes: The distance information is matched with one or more of the following when the distance information changes: the initial distance value, the intermediate distance value, the ending distance value, the distance change trend, the distance change speed and acceleration, and the distance change duration, in order to determine the opening and closing state of the cover plate and seat ring.
[0006] Optionally, the step of matching the distance information based on one or more of the following—the initial distance value, the intermediate distance value, the final distance value, the distance change trend, the distance change speed and acceleration, and the distance change duration—with the preset cover plate and seat ring movement trajectory distance information to determine the cover plate and seat ring opening and closing state includes: If the distance information changes, it is determined whether the starting distance value matches the starting distance of the target movement trajectory; If so, determine whether the distance values collected successively during the period conform to the distance change trend of the target movement trajectory and whether they are within the distance range of the target movement trajectory. The distance change trend of the open cover is monotonically increasing, and the distance change trend of the closed cover is monotonically decreasing. If so, determine whether the termination distance value of the change matches the termination distance of the target motion trajectory; If so, the switch status of the cover plate and seat ring is determined based on the target motion trajectory result.
[0007] Optionally, after determining whether the distance values collected successively during the period conform to the trend of the target movement trajectory distance and whether they are within the range of the target movement trajectory distance, the method further includes: If the number of distance values that do not conform to the target motion trajectory distance change trend or are not within the target motion trajectory distance range exceeds the preset maximum number of times, then the current change process is determined to not conform to the cover plate and seat ring switch state change.
[0008] Optionally, the method further includes: When the device is powered on, it acquires initial distance information through the TOF detection module. If the initial distance information matches the cover plate closing distance information, then the cover plate and seat ring switch state is initialized to the cover plate closed state; otherwise, it is initialized to the cover plate open state.
[0009] Optionally, before matching the distance information with the preset distance information of the cover plate and seat ring movement trajectory, the method further includes: The TOF detection module collects calibration distance information of the movement trajectory of the cover plate and seat ring at preset time intervals; The calibration distance information collected multiple times is weighted and averaged to determine the distance information of the preset cover plate and seat ring movement trajectory.
[0010] Optionally, comparing the distance information with a preset human body distance range to determine the user's usage scenario based on the comparison result and the switch status of the cover and seat ring, and performing large and small thrust actions according to the user's usage scenario, includes: If the cover plate and seat ring switch are in the seat ring open state, and the distance information meets the first preset human body distance range and continues to exceed the first preset time, then the user usage scenario is determined to be a standing scenario, and a small rushing action is performed after the user leaves.
[0011] Optionally, comparing the distance information with a preset human body distance range to determine the user's usage scenario based on the comparison result and the switch status of the cover and seat ring, and performing large and small thrust actions according to the user's usage scenario, includes: If the cover plate and seat ring switch states are in the open and closed state, and the distance information conforms to the second preset human body distance range and continues to exceed the second preset time, then the user usage scenario is determined to be a sitting scenario. When the user leaves within the third preset time, a small rushing action is performed; when the user leaves after the third preset time, a large rushing action is performed.
[0012] Secondly, embodiments of the present invention also provide a smart toilet seat, which includes an electronic lid, a seat ring, and a cover plate. The electronic lid is provided with a TOF detection module and includes a control module. The control module is used to execute the smart toilet flushing control method provided in any embodiment of the present invention.
[0013] Thirdly, embodiments of the present invention also provide a smart toilet, which includes the smart toilet seat provided in any embodiment of the present invention.
[0014] This invention provides a smart toilet flushing control method. First, a TOF (Time-of-Flight) detection module placed on the smart toilet's electronic lid collects distance information in real time. Then, the collected distance information is matched with preset distance information for the lid and seat's movement trajectories to determine their on / off states. Simultaneously, the collected distance information is compared with a preset human body distance range. Based on the comparison result and the determined lid and seat on / off states, the user scenario is determined, and a strong flush or weak flush is performed according to this scenario. The smart toilet flushing control method provided by this invention requires only a single TOF detection module to achieve low-cost intelligent recognition of strong and weak flushes, and is completely touchless, greatly facilitating user operation, especially for the elderly and those with mobility issues. Furthermore, through precise distance measurement and recognition of lid and seat movement patterns, it effectively avoids accidental touches caused by actions such as opening the lid, and can more accurately identify user scenarios to enable the men's weak flush function.

Detailed Implementation
[0016] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.
[0017] Before discussing the exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although the flowcharts describe the steps as sequential processes, many of these steps can be performed in parallel, concurrently, or simultaneously. Furthermore, the order of the steps can be rearranged. The process can be terminated when its operation is complete, but may also have additional steps not included in the figures. The process can correspond to a method, function, procedure, subroutine, subroutine, etc.
[0018] Example 1 Figure 1 This is a flowchart of the intelligent toilet flushing control method provided in Embodiment 1 of the present invention. This embodiment is applicable to various user scenarios (such as men using it standing up, men / women using it sitting down, etc.) to achieve automatic flushing control. Figure 1 As shown, the method specifically includes the following steps: S11. Distance information is collected in real time through the TOF detection module placed in the electronic seat of the smart toilet.
[0019] S12. Match the distance information with the preset distance information of the cover plate and seat ring movement trajectory to determine the opening and closing status of the cover plate and seat ring.
[0020] S13. Compare the distance information with the preset human body distance range, determine the user scenario based on the comparison result and the switch status of the cover plate and seat ring, and perform large and small punching actions according to the user scenario.
[0021] Specifically, such as Figure 2As shown, a smart toilet may include a toilet body 1 and a smart toilet seat connected to the toilet body 1. The smart toilet seat may further include an electronic lid 21, a seat ring 22, and a cover plate 23. Specifically, a TOF detection module 24 can be added to the electronic lid 21 at its center position for real-time distance measurement. It uses TOF (Time of Flight) technology to achieve accurate distance measurement. The detection direction can be set to detect the user's direction during normal use. An example of the effective sensing area of the TOF detection module 24 is shown below. Figure 3 As shown, Figure 3 The area in blue.
[0022] During daily use, the TOF detection module 24 can collect distance information in real time. When a user uses the toilet or opens / closes the lid and seat, the collected distance information changes. Meanwhile, the movement trajectory of the lid and seat is fixed each time; that is, the collected distance information is fixed for each opening / closing action. Therefore, when the distance information changes, it can be matched with preset lid and seat movement trajectory distance information to determine whether an opening / closing action is being performed, thus determining the current lid and seat open / closed state in real time. The preset lid and seat movement trajectory distance information can include opening distance, seat opening distance, closing distance, and seat closing distance, and can also include simultaneous opening / closing distance and simultaneous closing distance, etc. Simultaneously, it can determine whether a user is using the toilet based on real-time collected distance information. Specifically, it can compare the collected distance information with a preset human body distance range, and combine the comparison results with the real-time status of the lid and seat to determine the user scenario, such as a man standing or a man / woman sitting, etc., and then execute the appropriate flushing function based on the user scenario. In addition, if the lid and seat are not activated, flushing will not be performed, thus effectively preventing accidental flushing.
[0023] In an optional implementation, matching the distance information with the preset cover plate and seat ring movement trajectory distance information to determine the cover plate and seat ring switch state includes: matching the cover plate and seat ring switch state with one or more of the following: the starting distance value, the intermediate distance value, the ending distance value, the distance change trend, the distance change speed and acceleration, and the distance change duration when the distance information changes.
[0024] Specifically, the TOF detection module can collect data in real time at certain time intervals. When the collected distance information changes, the first distance value collected at the time of the change can be used as the starting distance value. Subsequently, when the distance information remains unchanged for a certain period of time or undergoes a sudden change, it can be considered that the change has ended, and the last collected distance value can be used as the ending distance value. The distance value collected between the starting distance value and the ending distance value is the interval distance value. If it is a cover plate and seat ring movement, the starting distance value and the ending distance value should be within a certain error range from the corresponding starting and ending values in the preset cover plate and seat ring movement trajectory distance information. At the same time, the interval distance value should also be within the allowable error range of the data group in the preset cover plate and seat ring movement trajectory distance information. Furthermore, the distance change trend during this change should also be the same as the corresponding trend in the preset cover and seat ring movement trajectory distance information. For example, the opening distance change trend is monotonically increasing, meaning the distance value gets larger and larger, while the closing distance change trend is monotonically decreasing, meaning the distance value gets smaller and smaller, etc. During the same switching process, the movement speed and acceleration are generally relatively stable without drastic fluctuations and can be close to the corresponding speed and acceleration in the preset cover and seat ring movement trajectory distance information. The duration of the distance change should also be within a certain range, compared to the corresponding duration in the preset cover and seat ring movement trajectory distance information; being too long or too short can be excluded. In summary, one or more of the following can be used to match the starting distance value, intermediate distance value, ending distance value, distance change trend, distance change speed and acceleration, and distance change duration with the preset cover and seat ring movement trajectory distance information to determine whether it is a cover and seat ring switching action. Thus, the cover and seat ring switching state can be updated according to the result state of the relevant action. For example, when the matching result is an opening action, the cover and seat ring switching state can be determined as the cover open state.
[0025] Optionally, the step of matching the distance information of the cover plate and seat ring with the preset movement trajectory distance information to determine the opening and closing state of the cover plate and seat ring based on one or more of the following: the starting distance value, the intermediate distance value, the ending distance value, the distance change trend, the distance change speed and acceleration, and the distance change duration when the distance information changes, includes: if the distance information changes, determining whether the starting distance value matches the starting distance of the target movement trajectory; if so, determining whether the successively collected intermediate distance values match the distance change trend of the target movement trajectory and whether they are within the distance range of the target movement trajectory, wherein the opening distance change trend is monotonically increasing and the closing distance change trend is monotonically decreasing; if so, determining whether the ending distance value of the change matches the ending distance of the target movement trajectory; if so, determining the opening and closing state of the cover plate and seat ring based on the result state of the target movement trajectory.
[0026] For example, taking the lid-opening action as an example, if the distance information changes, it is determined whether the initial distance value matches the starting distance of the lid-opening trajectory. Specifically, this could be the distance value when the lid is closed. If so, it can continue to determine whether the newly collected distance value is still changing; otherwise, it can determine whether it matches other action modes and enter other mode processing flow. If the newly collected distance value continues to change, it is determined whether the distance values collected during the period are monotonically increasing and whether they are within the distance range of the lid-opening trajectory. If so, it is determined whether the ending distance value of the change matches the ending distance of the lid-opening trajectory. Specifically, this could be the maximum value when the lid is open. If so, it can be determined that it is a lid-opening action, and the lid and seat ring switch status can be determined to be the lid-open state. If the ending distance value does not match the ending distance of the lid-opening trajectory, it can continue to determine whether the newly collected distance value continues to change and whether it is monotonically increasing and whether it is within the distance range of the lid-opening trajectory. Then, the ending distance value can be obtained again and determined whether it matches the ending distance of the lid-opening trajectory. This process can be repeated continuously. When the newly collected distance value does not change within the timeout period, the determination of the current change process can be ended.
[0027] Optionally, after determining whether the successively collected distance values conform to the target motion trajectory distance change trend and whether they are within the target motion trajectory distance range, the method further includes: if the number of distance values that do not conform to the target motion trajectory distance change trend or are not within the target motion trajectory distance range exceeds a preset maximum number, then the current change process is determined not to conform to the cover and seat ring switch state change. Again, taking the above-mentioned cover opening action as an example, when the newly collected distance value no longer satisfies monotonically increasing or is within the cover opening trajectory distance range, the number of errors is counted. When the count exceeds a preset maximum number, the determination of the current change process can end; otherwise, it can continue to determine whether the newly collected distance value continues to change, whether it monotonically increases, and whether it is within the cover opening trajectory distance range. An exemplary determination process is as follows: Figure 4 As shown. Furthermore, in the case of a cover-closing action, as the cover is about to close, the final distance gradually approaches the distance when the cover is completely closed, and the time spent after closing is often longer than the normal usage time of the user. Similar behavioral and temporal characteristics can be used as auxiliary data for judging the corresponding actions.
[0028] Based on the above technical solution, optionally, the method further includes: when the device is powered on, initial distance information is collected through the TOF detection module; if the initial distance information matches the cover plate closing distance information, the cover plate and seat ring switch state is initialized to the cover plate closed state, otherwise it is initialized to the cover plate open state.
[0029] Specifically, each time the device is powered on, the TOF detection module can be initialized and enter detection mode. If the detected initial distance information is the same as the distance when the cover is closed, or within a certain error range, it can be initially identified as the cover being closed. If the detected initial distance information is any other distance, it can be initially identified as the cover being open. Other states can be further corrected based on the subsequently detected opening and closing actions of the cover and seat ring, thus facilitating automatic flushing control using the cover and seat ring's opening and closing states.
[0030] Based on the above technical solution, optionally, before matching the distance information with the preset distance information of the cover plate and seat ring movement trajectory, the method further includes: collecting calibration distance information of the cover plate and seat ring movement trajectory through the TOF detection module at preset time intervals; and performing a weighted average of the calibration distance information collected multiple times to determine the preset distance information of the cover plate and seat ring movement trajectory.
[0031] Specifically, during the opening and closing motion of the cover and seat ring, they enter the effective sensing area of the TOF detection module. Since the movement trajectory of the cover and seat ring is relatively fixed each time, their entry position into the effective sensing area is also relatively fixed. Based on this, the identifiable distance information of the cover and seat ring can be determined, such as the initial distance, the final distance, and the distance during the movement. Furthermore, the distance change trend, the speed and acceleration of the distance change, and the duration of the distance change can also be obtained. Specifically, distance information of the cover and seat ring after entering the effective sensing area can be collected and recorded at preset time intervals for actions such as opening the cover, opening the seat ring, closing the cover, closing the seat ring, opening the cover and opening the seat ring, and closing the cover and closing the seat ring. Multiple measurements can be performed, and the calibrated distance information collected multiple times can be weighted and averaged to obtain the preset distance information of the cover and seat ring movement trajectory for each action.
[0032] Based on the above technical solution, optionally, the step of comparing the distance information with a preset human body distance range to determine the user usage scenario based on the comparison result and the switch status of the cover and seat ring, and performing a small and large rushing action according to the user usage scenario, includes: if the switch status of the cover and seat ring is the seat ring open state, and the distance information conforms to the first preset human body distance range and lasts for more than a first preset duration, then the user usage scenario is determined to be a standing scenario, and a small rushing action is performed after the user leaves. Preferably, the first preset human body distance range is 50-75 cm, and the first preset duration is 6 seconds.
[0033] Based on the above technical solution, optionally, comparing the distance information with a preset human body distance range to determine the user usage scenario based on the comparison result and the switch status of the cover and seat ring, and performing a small and large rushing action according to the user usage scenario, includes: if the switch status of the cover and seat ring is that the cover is open and the seat ring is closed, and the distance information conforms to the second preset human body distance range and continues for more than the second preset time, then the user usage scenario is determined to be a sitting scenario; when the user leaves within a third preset time, a small rushing action is performed; when the user leaves after the third preset time, a large rushing action is performed. Preferably, the second preset human body distance range is 5-50 cm, the second preset time is 6 seconds, and the third preset time is 60 seconds.
[0034] In addition, if the cover plate and seat ring switch are in the closed state, the detection frequency of the TOF detection module can be reduced, and it can be restored after detecting the opening action, so as to achieve lower power consumption.
[0035] An exemplary flushing control process is as follows: Figure 5 As shown, after power-on initialization, it determines whether the current initial distance information is the same as when the lid is closed. If so, it is determined to be in the lid-closed state; otherwise, it is in the lid-open state. When the lid is closed, if a distance change is detected, it determines whether the distance change trajectory is the same as the lid-opening action. If so, it updates to the lid-open state; otherwise, it remains in the lid-closed state. When the lid is open, if a distance change is detected, it first determines whether it matches the seat ring movement trajectory. If so, the seat ring state is updated; otherwise, it determines whether it matches a standing or sitting scenario. If so, it executes the corresponding flushing action if the corresponding time requirement is met; otherwise, it determines whether it matches the lid-closing trajectory. If so, it returns to the lid-closed state. By utilizing the precise distance measurement characteristics of Time-of-Flight (TOF) and employing algorithms to collect and model the movement trajectory data of the lid and seat ring, it can accurately identify whether the currently detected action is opening / closing the lid and seat ring or a normal usage scenario, thereby achieving precise automatic flushing control in multiple scenarios at low cost.
[0036] The technical solution provided by this invention first collects distance information in real time through a TOF detection module placed in the smart toilet seat. Then, it matches the collected distance information with preset distance information for the movement trajectories of the seat and lid to determine their open / closed states. Simultaneously, it compares the collected distance information with a preset human body distance range. Based on the comparison result and the determined open / closed states of the seat and lid, it determines the user scenario and performs a quick flush or light flush based on that scenario. Only one TOF detection module is needed to achieve intelligent recognition of quick flushes and light flushes at low cost, and it is completely touchless, greatly facilitating user operation, especially for the elderly and those with mobility issues. Furthermore, through accurate distance measurement and recognition of the seat and lid movement patterns, it effectively avoids accidental touches caused by opening the lid and other actions, and can more accurately identify user scenarios to enable the quick flush function for men.

The electronic lid is equipped with a TOF detection module, which can be located at the center line of the electronic lid. The detection direction can be set to the direction in which the user can be detected during normal use.
