[0043] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0044] Please refer to the attached Figure 1 - attached Figure 3 , an embodiment of the present invention provides an intelligent fully automatic bathing machine, including a base 1. A pressure sensor matrix 2 is arranged in the top groove of the base 1. An interlayer 3 is arranged on the top of the pressure sensor matrix 2. An airbag layer 4 is arranged on the top of the interlayer 3. One end of an air duct 5 is connected to the air inlet hole of the airbag layer 4, and the other end of the air duct 5 is connected to an air pump 6. A plurality of support columns 7 are installed on the outer wall of the base 1. The tops of the plurality of support columns 7 are installed with a circular slide rail 8. A moving component is arranged outside the circular slide rail 8. A shower angle adjusting mechanism is installed on the outer wall of the moving component, which is used to adjust the shower angle of the shower head according to the height of different users. Automatic scrubbing mechanisms are installed on both symmetric sides of the top of the base 1 through height adjusting components, which are used to flexibly clean the user's body.

[0045] Specifically, at the start of the device operation, the pressure sensor matrix 2 embedded in the base 1 is activated to collect real-time data on the distribution of the user's body weight. If abnormal body weight distribution is detected, such as the body weight suddenly concentrating on a single point (such as the buttocks) or disappearing, after analysis by the main control unit, it is determined as a fall situation, and at this time, the buffer protection mechanism is triggered. The air pump 6 quickly inflates the airbag layer 4 of the base 1 through the air duct 5, and the airbag expands to form a flexible buffer, effectively reducing the impact force of the fall. At the same time, the device emits a voice alarm and lights up a warning light to alert the user and surrounding people, and sends a notification to the preset contacts through the wireless communication module.

[0046] Please refer to the attached Figure 4 - attached Figure 6 , the moving component includes a sliding seat 9, the sliding seat 9 is sleeved outside the circular slide rail 8, four through holes 10 are penetrated through the middle parts of the upper and lower sides of the sliding seat 9, an installation rod 11 is penetrated through each through hole 10, mounting seats one 12 are rotatably arranged on the upper and lower sides of the outer wall of each installation rod 11, one end of a damper 13 is rotatably arranged in the middle of each mounting seat one 12, the other end of the damper 13 is rotatably arranged on the outer wall of the sliding seat 9, a mounting plate 14 is arranged at the position of the outer wall of the installation rod 11 below the bottom mounting seat one 12, a motor one 15 is arranged at the end of the installation rod 11, the motor one 15 is mounted at the bottom of the mounting plate 14, a pulley 23 is fixed on the outer wall of the installation rod 11, and the outside of the pulley 23 is arranged in the chute on the outer wall of the circular slide rail 8.

[0047] Specifically, when the fully automatic bathing machine of the present invention is operating, the system sends a driving instruction to start the motor one 15, driving the installation rod 11 to rotate in the through hole 10, thereby controlling the synchronous rotation of the pulley 23, so that the pulley 23 rotates along the groove on the outer wall of the circular slide rail 8, thereby driving the sliding seat 9 to move outside the circular slide rail 8. At this time, when the sliding seat 9 moves, the pulley 23 is affected by the outer wall of the circular slide rail 8 and will move, and at this time, the installation rod 11 will be affected by the pulley 23, driving the mounting seat one 12 to move synchronously, and then driving the damper 13 to operate, so as to ensure that the pulley 23 always fits the outer wall of the circular slide rail 8, further ensuring the stable operation of the moving component. Driven by the operation of the moving component, its spray angle adjustment mechanism will move synchronously, and then drive the shower head to move along a circular track along the airbag layer 4, so that the water sprayed by the shower head can clean all positions of the user's whole body.

[0048] Please refer to the attached Figure 5 and attached Figure 7 , the spray angle adjustment mechanism includes a fixed seat 16, the outer wall of the fixed seat 16 is mounted on the bottom of the sliding seat 9, the lower surface of the fixed seat 16 is connected with an electric telescopic rod one 18 through a hinge 17, a bracket 19 is fixed at the driving end of the electric telescopic rod one 18, and a limiting component is arranged on the outer wall of the bracket 19.

[0049] The limiting component includes a movable sleeve 20. One end of the movable sleeve 20 rotates on the outer wall of the sliding seat 9. A first spring 21 is arranged inside the movable sleeve 20. One end of the first spring 21 is installed on the inner wall of the movable sleeve 20, and the other end of the first spring 21 is connected to one end of an installation clamping rod 22. The other end of the installation clamping rod 22 is clamped in the U-shaped groove outside the bracket 19.

[0050] Specifically, when the spray angle adjustment mechanism operates, it is responsible for driving the shower head to move in a fan-shaped trajectory, so as to further meet the cleaning of different body parts of the user. The specific operation principle of this mechanism is that the first electric telescopic rod 18 is started. At this time, it pushes the bracket 19 downward, and the synchronous hinge 17 unfolds to provide a limit for the first electric telescopic rod 18. At this time, the bracket 19 is controlled by the limiting component to adjust the angle. At this time, the installation clamping rod 22 in the limiting component will move synchronously in the movable sleeve 20 under the operation of the bracket 19, so as to stretch or compress the first spring 21. While assisting the bracket 19 to reset, it can also ensure that the moving direction of the bracket 19 is fixed and provide enough moving space for it.

[0051] Please refer to the attached Figure 8 - attached Figure 10 The height adjustment component includes two mounting columns 24. Both of the two mounting columns 24 are mounted on the top of the base 1. Linear guide rails 25 are installed in the grooves on both sides of the two mounting columns 24. A moving seat 26 is arranged outside each group of linear guide rails 25, and the outside of the moving seat 26 is arranged between the two mounting columns 24.

[0052] The automatic scrubbing mechanism includes a flexible roller 34. The flexible roller 34 is installed on the top of the moving seat 26 through a position adjustment component. A second motor 36 is installed on the outer wall of the position adjustment component. A second pulley 37 is installed at the driving end of the second motor 36. A first pulley 35 is installed at the end of the flexible roller 34. A belt 38 is sleeved outside the second pulley 37 and the first pulley 35.

[0053] The position adjustment component includes a movable arm 27. One end of the movable arm 27 rotates on the top of the moving seat 26. A limiting rod 28 is installed in the through groove in the middle of the movable arm 27. A second spring 29 is sleeved outside the limiting rod 28. A moving arm 30 slides on the outer wall of the limiting rod 28. One end of the second spring 29 is connected to the inner wall of the through groove in the middle of the movable arm 27, and the other end of the second spring 29 is connected to the inner wall of the moving arm 30. The outer wall of the flexible roller 34 rotates in the middle of the moving arm 30.

[0054] Mounting seats two 32 are installed on the outer walls of the two mounting columns 24. An electric telescopic rod two 33 rotates inside the mounting seat two 32. The driving end of the electric telescopic rod two 33 is installed with a connecting seat 31 through a rotating shaft, and the top of the connecting seat 31 is installed at the bottom of the moving arm 30.

[0055] Specifically, during actual use, after the user starts the bathing machine, the system drives the height adjustment component to work according to the preset height data. The linear guide rail 25 drives the automatic scrubbing mechanism to slide up and down along the mounting column 24, adjusting the flexible roller 34 to the height of the target cleaning area, such as the shoulder, back or waist. The flexible roller 34 starts to rotate driven by the second motor 36, and realizes a continuous and stable cleaning effect through belt transmission 38.

[0056] When the flexible roller 34 touches the user's body, the position adjustment component comes into play. The second electric telescopic rod 33 is activated, driving the moving arm 30 to rotate on the top of the moving seat 26. Synchronously driven by the second electric telescopic rod 33, the moving arm 30 moves along the outer wall of the limiting rod 28 in the middle of the movable arm 27, thereby squeezing the second spring 29 to generate a resilient force, enabling the flexible roller 34 to adapt to the body's curvature or different part curves, and at the same time ensuring that the contact pressure is appropriate and will not cause too much burden on the skin. During cleaning, while the flexible roller 34 is rotating, it dynamically adjusts the contact angle and force according to real-time feedback to ensure uniform coverage of cleaning. Under the operation of one side of the flexible roller 34, the flexible roller 34 on the other side will perform the above operations synchronously, thereby controlling the flexible roller 34 on the other side to move to the most suitable position for the user to climb and hold, so as to facilitate the user to maintain balance.

[0057] After completing the cleaning of one area, the system drives the height adjustment component again to move the automatic scrubbing mechanism to the next target area, such as moving from the back to the waist. The flexible roller 34 continues to work in the same way, adapting to the new cleaning area through dynamic position adjustment. During the cleaning process, if the user's posture changes, the second electric telescopic rod 33 will be driven to make the moving arm 30 automatically adjust the fitting position of the flexible roller 34 to ensure the efficient operation of the device and the comfort of the user.

[0058] After the cleaning is completed, the device automatically resets. The automatic scrubbing mechanism returns to the initial position through the second electric telescopic rod 33, the flexible roller 34 stops rotating, and the movable arm 27 and the moving arm 30 are adjusted to the original state, completing the entire cleaning process. Throughout the process, the system combines flexible scrubbing with dynamic height adjustment to ensure the comprehensiveness, comfort and safety of cleaning.

[0059] Please refer to the attached Figure 11 , an intelligent fully automatic bathing machine is driven by an intelligent fully automatic bathing machine system, including:

[0060] A fall detection and buffer protection module, which is used to monitor the weight distribution of the user in real time, judge whether a fall or abnormal posture occurs, and trigger buffer protection;

[0061] The spray angle automatic adjustment module is used to control the position and angle of the spray mechanism, complete the dynamic adjustment of the shower head within the circular slide rail 8, and adapt to the cleaning of different heights and body parts;

[0062] The height automatic adjustment module is used to realize the height control of the automatic scrubbing mechanism and adapt to the cleaning needs of users of different heights;

[0063] The flexible scrubbing drive module is used to drive the flexible roller 34 to automatically fit the user's body for dynamic scrubbing;

[0064] The mobile execution control module is responsible for controlling the operation of the mobile components and completing the positioning of the spray mechanism and the scrubbing mechanism;

[0065] The automatic handrail adjustment module is used to automatically adjust the height and position of the flexible roller 34 on the user side, provide a stable support point, and prevent the user from falling;

[0066] The main control and data feedback module is responsible for receiving, analyzing the data of each module and coordinating the control.

[0067] Specifically, through the collaborative work of multiple modules, this intelligent fully automatic bathing machine realizes the full-process automation from fall monitoring, safety protection to intelligent cleaning. The system dynamically adapts to the body characteristics and cleaning needs of different users through core technologies such as the height adjustment module, the spray angle adjustment module, and the flexible scrubbing module. At the same time, through the coordination and control of the main control and data feedback module, the intelligent operation of the device is realized. The device design comprehensively considers the comfort, safety and cleaning efficiency of the user, and is suitable for various users, especially the group with inconvenient mobility or in need of assisted cleaning.

[0068] In this embodiment, the fall detection and buffer protection module real-time monitors the weight distribution of the user through the pressure sensor matrix embedded in the base 1. The data collected by the pressure sensor is transmitted to the main control unit through the data acquisition circuit, and the main control unit calculates the dynamic change of the weight distribution through the algorithm. If the weight concentration point suddenly shifts to a single position (such as the buttocks) or the distribution is abnormal (such as the partial or complete disappearance of the weight), the system determines that the user may fall or stand unsteadily.

[0069] After detecting the fall situation, the main control unit sends an instruction to the air pump 6, and the air pump 6 inflates the airbag layer 4 in the base 1 through the air duct. The airbag layer 4 quickly expands within 0.5 seconds to form a buffer structure and reduce the impact force when the user falls. In addition, the system triggers a voice alarm and a warning light, and sends a notification to the preset contact person through the wireless module.

[0070] In this embodiment, the spray angle automatic adjustment module controls the horizontal position of the shower head through the circular slide rail 8 and adjusts the spray angle of the shower head through the angle adjustment mechanism. The sliding seat 9 drives the pulley 23 to slide within the circular slide rail 8 through the motor, realizing the stable movement of the shower head on the rail. The angle adjustment is completed by the electric telescopic rod 18. The telescopic rod adjusts the angle between the support 19 and the shower head to adapt to users of different heights or the target parts to be cleaned.

[0071] In this embodiment, the height automatic adjustment module uses the moving seat 26 installed on the linear guide rail 25 to complete the height adjustment of the flexible scrubbing mechanism. The electric telescopic rod drives the moving seat 26 to slide up and down along the linear guide rail 25 to ensure that the scrubbing mechanism can cover all target areas of the user's body.

[0072] The position of the moving seat 26 is fed back to the main control unit in real time through the limit sensor, and the main control unit dynamically adjusts the height according to the user's height or the specified cleaning requirements.

[0073] In this embodiment, the flexible scrubbing drive module drives the flexible roller 34 to rotate at a high speed through the motor to realize the cleaning of the user's body surface. The flexible roller 34 is connected to the motor through the belt drive system, and the motor speed can be dynamically adjusted according to the user's cleaning requirements to ensure the cleaning effect while ensuring comfort.

[0074] The fitting position of the flexible roller 34 is controlled by the position adjustment component. The movable arm 27 and the moving arm 30 are dynamically adjusted through the spring and the limit rod 28. The spring provides a buffering effect, enabling the flexible roller 34 to adapt to the user's body curve and avoiding discomfort caused by excessive pressure.

[0075] In this embodiment, the moving execution control module is responsible for the positioning of the spray mechanism and the flexible scrubbing mechanism. The sliding seat 9 moves along the circular slide rail 8, and the precise positioning is completed by driving the pulley 23 through the motor 15. The movement of the flexible scrubbing mechanism is realized through the height adjustment module. The stability of the moving execution is guaranteed by the damper 13 to avoid positioning errors caused by the vibration of the slide rail.

[0076] In this embodiment, the automatic handrail adjustment module provides the handrail function for the user by adjusting the height of one side of the flexible roller 34. The height adjustment is linked with the height automatic adjustment module, and the handrail height is adjusted according to the natural position of the user's arms. At the same time, the force on the handrail is monitored through the pressure sensor to prevent the user from falling.

[0077] In this embodiment, the main control and data feedback module is responsible for coordinating the operation of each module. The main control unit integrates the pressure sensor, the limit sensor, and the motion feedback data, analyzes the user's current state, and dynamically adjusts the device operation parameters. The main control unit also records the user usage data, including the cleaning time, the pressure change, and the movement trajectory, for optimizing the device settings or generating usage reports.

[0078] This intelligent fully automatic bathing machine realizes the full - process automation function from safety protection to dynamic cleaning through the coordinated work of multiple modules such as the fall detection and buffer protection module, the automatic spray angle adjustment module, and the height automatic adjustment module. The operation logics of each module are closely connected. Utilizing the intelligent control and real - time adjustment of the main control and data feedback module, it ensures the high efficiency, adaptability, and safety of the device.

[0079] Please refer to the appendix Figure 12 , the fall detection and buffer protection module includes:

[0080] A pressure sensing unit, which is used to monitor the change of the user's weight distribution and judge whether there is an abnormality;

[0081] A buffer trigger unit, which is used to quickly trigger the inflation of the airbag layer after detecting a fall situation;

[0082] An alarm and linkage unit, which is used to trigger the alarm function to remind the user after fall detection and remotely notify relevant personnel;

[0083] A data analysis and main control unit, which is used to analyze the pressure data, judge whether to trigger the protection mechanism, and provide functions such as sensitivity adjustment, data recording, and feedback.

[0084] Specifically, in this embodiment, the pressure sensing unit is installed inside the device base 1 and consists of a high - precision pressure sensor matrix. The sensors continuously monitor the change of the user's weight distribution, collect the pressure data through the circuit and transmit it to the main control unit. The main control unit judges whether the user is in a normal use state by calculating the dynamic change of the weight distribution.

[0085] Normal state: The weight distribution is uniform, mainly concentrated on the two - foot support points.

[0086] Abnormal state: The weight distribution suddenly concentrates on a single point (such as the buttocks) or partially disappears, which may be a fall situation.

[0087] The judgment formula for calculating the pressure distribution is:

[0088]

[0089] where p(x i , y i ) is the pressure value of the i - th pressure sensor, and P total is compared with the standard value of the user's weight. When the difference exceeds the threshold, it is determined that there may be an abnormality.

[0090] In this embodiment, when the main control unit detects an abnormal weight distribution, it immediately activates the buffer trigger unit. This unit includes an air pump 6, an air duct 5, and an airbag layer 4.

[0091] The main control unit sends an instruction to the air pump 6, and the air pump 6 rapidly inflates the airbag layer 4 through the air duct 5.

[0092] The airbag layer 4 expands to the set thickness (about 5 cm) within a short time (<500 ms), forming a flexible buffer area to prevent the user from being seriously injured due to direct contact with the ground when falling.

[0093] The inflation rate triggered by the buffer is controlled by the following formula:

[0094]

[0095] Where, V inflate is the inflation volume of the airbag, P pump is the pressure of the air pump 6, and R flow is the flow resistance of the air duct.

[0096] In this embodiment, when a fall is detected and the buffer protection is triggered, the alarm and linkage unit starts to work.

[0097] The system issues a voice prompt through the speaker (such as "Fall detected, request for support") and lights up a red warning light to alert the surrounding people.

[0098] At the same time, the system sends notifications to the preset contacts through the wireless module, including data such as the user's status, fall time, and ambient temperature.

[0099] If no one responds to the notification within the preset time, the system will link the emergency call service module to automatically call the emergency rescue phone and send the location information.

[0100] The trigger conditions for the alarm linkage are:

[0101] When the pressure sensor matrix monitors an abnormal weight distribution and, after being judged by the main control unit, it is confirmed that there is a possibility of falling or instability while standing, the system triggers the alarm linkage function. The specific trigger conditions are as follows:

[0102] Trigger condition formula:

[0103]

[0104] Where: T alert is the alarm linkage status (1 indicates triggering the alarm, 0 indicates not triggering), P total is the total pressure value monitored in real time, P baseline is the reference pressure value set according to the user's weight and normal standing or sitting posture, and ΔP threshold is the pressure abnormality threshold set by the system to judge whether there is an abnormal weight distribution.

[0105] Logical explanation:

[0106] When the total real-time pressure value P total and the reference pressure value P baseline have a difference exceeding the abnormal threshold ΔP threshold , the system determines it as an abnormal situation and triggers the alarm linkage function.

[0107] If the difference is within the threshold range, the system considers the user to be in a normal usage state and does not trigger an alarm.

[0108] This triggering condition ensures a balance between sensitivity and accuracy during system operation, effectively avoiding false alarms caused by minor weight changes or normal movements (such as bending down, adjusting posture), while ensuring a quick response to real falls or abnormal situations.

[0109] The core of the data analysis and main control unit is the dynamic analysis of pressure data and triggering subsequent protection and alarm functions based on abnormal situations. Its triggering condition is based on abnormal changes in pressure distribution and dynamic monitoring, and the specific formula is as follows:

[0110]

[0111] Where: S anomaly is the total judgment value of abnormal weight distribution, P current,i is the current pressure value at the i-th point in the pressure sensor matrix, P baseline,i is the reference pressure value at the i-th point under normal conditions, ΔS threshold is the triggering threshold for abnormal distribution, which is dynamically adjusted according to the user's weight, body shape, and usage scenario. When S anomaly exceeds the set threshold ΔS threshold , the main control unit triggers the protection and alarm process.

[0112] Operation logic:

[0113] Real-time data acquisition: The main control unit receives real-time data from the pressure sensing unit, calculates the dynamic changes in weight distribution, and records the overall state of the pressure sensor matrix.

[0114] Dynamic sensitivity adjustment: The system automatically adjusts the abnormal threshold ΔS threshold according to the user's weight, height, and preset parameters to ensure that the sensitivity adapts to different user needs and avoid false alarms.

[0115] Abnormal judgment and linkage trigger: If the abnormal value S of the pressure distribution anomaly exceeds the threshold, the main control unit immediately:

[0116] Sends an instruction to the buffer trigger unit to activate the protection of the airbag layer 4.

[0117] At the same time, activates the alarm and linkage unit to start voice prompts, warning lights, and remote notifications.

[0118] Data recording and feedback: The main control unit records pressure data, trigger time and operating status to internal storage or uploads to the cloud for users or caregivers to view and analyze. In addition, users can view recorded data through the touch screen or mobile app and adjust parameters such as sensitivity and response time.

[0119] Working principle: When the device starts running, the pressure sensor matrix 2 embedded in the base 1 is started to collect the user's weight distribution data in real time. If it is detected that the user's weight distribution is abnormal, such as the weight suddenly concentrated on a single point (such as the buttocks) or disappears, the main control unit will analyze and determine it as a fall situation, and then trigger the buffer protection mechanism. The air pump 6 quickly inflates the airbag layer 4 of the base 1 through the air guide tube 5, and the airbag expands to form a flexible buffer, which effectively reduces the impact force of the fall. At the same time, the device issues a voice alarm and lights up the warning light to remind the user and surrounding people, and sends notifications to the preset contacts through the wireless communication module.

[0120] During the cleaning process, the device adjusts the shower position through the slide 9 on the slide rail according to the user's height and cleaning needs. The slide 9 is driven by a motor 15 to drive the pulley 23 to slide along the circular slide rail 8 to ensure that the shower can cover the user's entire body. The shower angle is controlled by the spray angle adjustment mechanism, and the electric telescopic rod 18 drives the bracket 19 to adjust the inclination angle of the shower to adapt to the body shape and bathing posture of different users. The main control unit dynamically adjusts the spray range and water flow intensity according to the user's settings to ensure the efficiency and comfort of cleaning.

[0121] The automatic scrubbing mechanism cooperates with the height adjustment component to control the up and down movement of the flexible roller 34 through the linear guide 25 to adapt to the user's height and the cleaning part. The flexible roller 34 is driven by the motor 2 36 to rotate at high speed. At the same time, the movable arm 27 and the movable arm 30 installed on it can adjust the fitting position according to the user's body curve through the electric telescopic rod 2 33 to ensure that the scrubbing process is both efficient and gentle. When support is needed, one side of the flexible roller 34 can be adjusted to the height of the armrest to help the user stay stable.

[0122] The entire system is coordinated by the main control unit. The main control unit integrates real-time data from pressure sensors, limit feedback and automatic scrubbing mechanisms, dynamically optimizes the operation of each module, and generates a user usage report for reference. Users can also view the device status in real time through the touch screen or mobile app, set bathing parameters or end the operation. After the work is completed, the device automatically shuts down to ensure safety and energy saving.
