[0002] Traditional bathing methods have numerous limitations in terms of comfort, convenience, and personalized service. Existing bathing equipment typically only allows for simple water temperature adjustment and relies heavily on manual operation, failing to automatically adjust to individual skin conditions and bathing habits. For example, elderly people and children have different sensitivity to water temperature, making manual adjustment difficult to precisely meet their needs. Furthermore, the equipment lacks intelligent features and cannot automatically control the use of shower gel and shampoo based on user preferences.

[0003] For example, a bathing system and a control method for a bathing system disclosed in Public (Announcement) No. , the bathing system includes: a shower device; a bathing mat with a weighing function; a controller, the controller communicates with the bathing mat and the shower device respectively, the controller records the weight parameters collected by the bathing mat and the operating parameters of the shower device when the user takes a shower for the first time, and performs identity matching on the current weight parameters and the recorded weight parameters when the user takes a shower for the next time, and if the identity matching is successful, the shower device is controlled according to the recorded operating parameters corresponding to the recorded weight parameters.

[0004] Based on the above, it can be seen that the following technical problems exist in the existing technology: During the use of the above-mentioned existing technology, the bathing method has some automatic adjustment functions, but it only makes limited adjustments based on the preset program. When faced with the diverse needs of users and special bathing scenarios, it is difficult to make accurate responses due to the inability to deeply analyze skin physiological data. This not only affects the user's bathing experience, but may also lead to waste of water resources and energy. For this reason, we propose a skin-sensing bathing method and a smart shower.

It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention. Example

[0022] Reference Figure 1-3 , a skin-feeling bathing method, comprising the following steps: S1: During the bathing process, multiple skin monitoring sensors installed on the smart shower are used. The skin monitoring sensors are respectively attached to the head, shoulders, back, and limbs of the human body, and the skin temperature is collected in real time according to the preset time intervals. ,humidity , blood flow velocity Physiological parameters; S2: Pre-process the collected physiological parameters, use the Kalman filter algorithm to filter out high-frequency noise, and then convert the temperature The data is normalized to the interval [0,1], humidity The data is normalized to the interval [0,1], blood flow The speed data is normalized to the interval [0,1] to form the skin feeling data; S3: The pre-processed skin sensory data is transmitted to the intelligent processing system for analysis and evaluation based on a pre-established human skin sensory model; S4: Based on the skin feel evaluation results, the smart showerhead automatically adjusts shower parameters, including shower gel and shampoo output, water temperature, water flow intensity, water flow pattern, and nozzle position and angle; S5: Continuously monitor skin sensation data and dynamically adjust bathing parameters to form a real-time feedback control closed loop, ensuring that human skin can feel a comfortable and appropriate bathing environment throughout the bathing process. After pre-processing and transmission to the intelligent processing system for analysis and evaluation, various bathing parameters are automatically adjusted based on the evaluation results to form a real-time feedback control closed loop, realizing comprehensive monitoring and dynamic optimization of the bathing environment, meeting the personalized needs of different people, different body parts and skin for bathing conditions at different bathing stages, and greatly improving the comfort and intelligence level of bathing.

[0023] The steps for preprocessing the collected physiological parameters are as follows: Step 1: Use the Kalman filter algorithm to filter the collected physiological parameters to remove high-frequency noise; Step 2: Normalize the filtered temperature T data. The normalization formula is: ; in, is 34°C, 40℃; Step 3: Normalize the humidity H data after filtering. The normalization formula is: ; in, is 30%, 70%; Step 4: Normalize the filtered blood flow velocity data.

Bathing parameter adjustment The steps for constructing the human skin feel model are as follows: Step 1: Use the Internet of Things to collect skin sensation data from 1,000 different people in different bathing environments, including skin temperature, humidity, blood flow velocity, and corresponding subjective comfort evaluation, which is divided into 1-10 levels; Step 2: Use the support vector machine algorithm to train the collected data to obtain a mapping relationship model between skin comfort and physiological parameters, which is expressed as follows: ; Step 3: Calculate the skin comfort level based on the mapping relationship model in step 2 The human skin feel model can scientifically and accurately reflect the intrinsic relationship between skin comfort and skin physiological parameters.

[0024] Set the comfort target threshold range to 7-8. If the comfort level is not within the target threshold, the bathing parameter adjustment phase begins. ,in The system is based on the real-time values ​​and change rates of various physiological parameters at level 7.5. The adjustment amount of the bathing parameters is calculated through a preset parameter adjustment algorithm. Based on the skin comfort level deviation and the real-time values ​​and change rates of various physiological parameters, it avoids blindness and excessive deviation in the adjustment process, satisfies the comfort needs of the human body in different skin conditions to the greatest extent, and further optimizes the bathing experience.

[0025] The parameter adjustment algorithm includes the adjustment of water flow pattern, water flow intensity and nozzle angle, and the expression is: ; in, Represents the amount of water flow pattern adjustment, corresponding to the change in the amount of water flow rhythm, and its coding range is 1-5; ; in, Represents the water flow intensity adjustment, unit is L / min; ; in, Indicates the nozzle angle adjustment amount in degrees. Example

[0026] Further optimizing Example 1, specifically, the steps of continuously monitoring skin sensation data and dynamically adjusting bathing parameters are as follows: Step 1: Repeat the steps of skin feel monitoring and pretreatment, skin feel evaluation, bathing parameter adjustment strategy determination, and bathing parameter execution adjustment according to the preset monitoring frequency, where the monitoring frequency is once every 10 seconds; Step 2: Maintain the adjusted bathing parameters for 10 seconds to allow the skin to adapt to the new bathing environment; Step 3: A real-time feedback control loop ensures that the skin remains comfortable throughout the bathing process, and that bathing parameters are adjusted smoothly. Each step is repeated at the set monitoring frequency, forming a real-time feedback control loop. This ensures that changes in skin sensation data are captured promptly during the bathing process and that corresponding parameter adjustments are made. The adjusted bathing parameters are maintained for a certain period of time, allowing the skin sufficient time to adapt to the new bathing environment and avoiding irritation caused by frequent parameter changes. This ensures comfort throughout the bathing process and improves the overall bathing effect and user experience. Example
