Description

Technical Field

[0001] This invention belongs to the field of bathroom ventilation and oxygen supply technology, specifically relating to an integrated fresh air and oxygen supply system and control method suitable for healthy showering. Background Technology

[0002] The statements herein provide only background information in relation to this invention and do not necessarily constitute prior art.

[0003] With the improvement of living standards, the family bathroom has become a frequently used living space for residents. During bathing, the hot water spray produces a large amount of water vapor, significantly increasing the water vapor content in the bathroom air. This reduces the proportion of breathable air per unit volume, resulting in a lower relative oxygen content. Simultaneously, the heat stimulation during bathing increases heart rate and circulatory load. Prolonged bathing in an environment with reduced oxygen levels can easily trigger discomfort such as chest tightness, palpitations, and dizziness, and in severe cases, may induce cardiovascular and cerebrovascular diseases. These risks are particularly pronounced in high-risk cardiovascular groups such as the elderly.

[0004] The inventors discovered that existing bathroom ventilation or fresh air systems mostly use a fixed height and fixed air volume supply method, which cannot provide directional airflow to different breathing areas of the human body. At the same time, existing technologies generally lack the ability to sense the physiological state of the human body during bathing, and cannot dynamically adjust the airflow and oxygen supply according to the user's physiological response, making it difficult to reduce physiological risks in a timely manner. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated fresh air and oxygen supply system and control method suitable for healthy showering. This system can comprehensively regulate the air supply and oxygen supply during the bathing process by combining the characteristics of the human breathing area, the comfort requirements of air supply, and changes in human physiological parameters.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the technical solution of the present invention provides an integrated fresh air and oxygen supply system suitable for healthy showering, comprising: an air supply and oxygen supply device, an exhaust device, a human physiological parameter acquisition module, and a central control module; the air supply and oxygen supply device is provided with an integrated air outlet, the interior of which is divided into three independent air supply channels along the vertical direction, each corresponding to a different human breathing zone height; the air supply and oxygen supply device is arranged opposite to the exhaust device, forming a directional airflow channel in the shower room from the air supply side to the exhaust side; the central control module is connected to each functional module and is configured to control the air supply and oxygen supply device to provide directional air and oxygen supply to the corresponding breathing zone height according to preset parameters or human physiological parameters acquired by the human physiological parameter acquisition module.

[0007] In at least one embodiment, the air supply and oxygen supply device further includes a fresh air inlet, a filter, an oxygen supply device, an oxygen mixing and regulating unit, and an air supply fan; wherein, the filter is located at the fresh air inlet; the oxygen mixing and regulating unit is connected to the oxygen supply device through an oxygen delivery pipeline; and the speed of the air supply fan is adjusted by a central control module to control the air supply volume.

[0008] In at least one embodiment, the three independent air supply channels are a high-level air supply channel, a middle-level air supply channel, and a low-level air supply channel, which correspond to the high-level breathing region, the middle-level breathing region, and the low-level breathing region, respectively; the high-level air supply channel, the middle-level air supply channel, and the low-level air supply channel are respectively provided with a first electric air valve, a second electric air valve, and a third electric air valve.

[0009] In at least one embodiment, a temperature regulation module is provided downstream of the air supply fan, the temperature regulation module including a PTC electric heater and an air supply temperature sensor.

[0010] In at least one embodiment, the human physiological parameter acquisition module includes a wearable physiological parameter monitoring device worn by the user, which establishes a data connection with the central control module and sends the acquired human physiological parameters to the central control module.

[0011] Secondly, the technical solution of the present invention also provides a control method for an integrated fresh air and oxygen supply system suitable for healthy showers, including: The intelligent control panel provides users with an air supply channel selection interface. Users can manually select to open the high-level air supply channel, the medium-level air supply channel, or the low-level air supply channel. Based on the user's selection, the electric air valve corresponding to the selected air supply channel is opened, and the unselected air supply channels are closed. Users can manually set the target air supply volume and adjust the speed of the air supply fan according to the target air supply volume so that the air supply system operates according to the target air supply volume. Users can manually set the target air supply temperature according to their personal comfort needs, and control the working state of the PTC electric heater in the temperature regulation module according to the target air supply temperature to keep the air supply temperature stable near the target air supply temperature. When the target air supply temperature set by the user exceeds the safe temperature range allowed by the system, the target air supply temperature is limited, and a prompt message is sent to the user through the intelligent control panel to prevent the user from experiencing discomfort or safety risks due to excessively low or high air supply temperatures.

[0012] In at least one embodiment, the system further includes: providing a user with an oxygen supply function selection interface, whereby the user selects to turn the oxygen supply function on or off; when the user selects to turn the oxygen supply function on, the oxygen generator is controlled to start, so that oxygen enters the oxygen mixing and regulating unit through the oxygen delivery pipe, mixes with fresh air, and is then sent to the air supply system; when the user selects to turn off the oxygen supply function, the central control module controls the oxygen generator to stop working, and the system only provides fresh air to the air supply system.

[0013] Thirdly, the technical solution of the present invention also provides another control method for an integrated fresh air and oxygen supply system suitable for healthy showers, including: Calculate the current user's breathing zone height based on the user's input height; Based on the current user's breathing zone height, the central control module divides the human breathing zone into zones. If the current user's breathing zone height does not exceed the first height boundary value, the current user is in the low breathing zone, the third electric air valve is opened, and the remaining air valves are closed. If the current user's breathing zone height is greater than the first height boundary value but does not exceed the second height boundary value, the current user is in the middle breathing zone, the second electric air valve is opened, and the remaining air valves are closed. If the current user's breathing zone height is greater than the second height boundary value, the current user is in the high breathing zone, the first electric air valve is opened, and the remaining air valves are closed. Based on the current breathing zone, determine the corresponding target air volume and adjust the air supply fan speed to deliver air.

[0014] In at least one embodiment, a supply air temperature comfort monitoring and control step is further included, specifically comprising: Real-time monitoring of supply air temperature; The comfort level of the supply air temperature is assessed based on the real-time supply air temperature, and corresponding controls are implemented based on the assessment results. If the real-time supply air temperature is lower than the lowest temperature threshold of the comfortable supply air temperature range, it is determined that there is a risk of cold air blowing directly, and the temperature regulation module is activated to heat the supply airflow. If the real-time supply air temperature is between the lowest temperature threshold and the highest temperature threshold of the comfortable supply air temperature range, it is determined that the current supply air temperature is in the comfortable range, and the temperature regulation module is controlled to maintain a constant working state so that the supply air system continues to operate at the current temperature. If the real-time supply air temperature is greater than the highest temperature threshold of the comfortable supply air temperature range, it is determined that there is a risk of overheating in the supply air. The temperature regulation module is controlled to reduce the heating power, and the supply air temperature is gradually reduced to the comfortable range through natural ventilation of the supply air system.

[0015] In at least one embodiment, a human physiological risk monitoring and control step is further included, specifically comprising: Real-time monitoring of the user's heart rate and heart rate variability during the bathing process; The user's physiological risk status is determined based on their real-time heart rate and heart rate variability during the bathing process, and the air supply and oxygenation are controlled accordingly based on the assessment results. If the user's real-time heart rate is greater than the preset safe heart rate threshold, or the user's real-time heart rate change rate is greater than the preset safe heart rate change rate threshold, the user is determined to be in a state of increased physiological risk when one of the above conditions is met. Under the premise of maintaining the current air supply height and air supply temperature control strategy unchanged, the oxygen supply device is activated, so that oxygen enters the oxygen mixing adjustment unit through the oxygen delivery pipe, mixes with fresh air and enters the air supply system to enhance the oxygen supply capacity of the human breathing area.

[0016] The beneficial effects of the above-described technical solution of the present invention are as follows: 1) This invention enables the air supply system to adapt to the breathing zone needs of different heights and users by dividing the air supply airflow height into zones. It is suitable for various usage scenarios such as children, adults and the elderly, and has strong versatility and applicability.

[0017] 2) This invention controls the oxygen supply process based on the user's physiological parameters. When an increase in physiological load is detected, the oxygen supply regulation is automatically activated, thereby providing safety protection during the bathing process and reducing the possibility of health risks caused by abnormal physiological state.

[0018] 3) This invention provides both automatic control mode and manual control mode. Users can switch between modes according to their needs, which improves operational flexibility while ensuring the safe operation of the system and avoids the limitations caused by the single operating mode of the system.

Detailed Implementation

[0022] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0023] As described in the background section, the purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated fresh air and oxygen supply system and control method suitable for healthy showering. This system can comprehensively regulate the air supply and oxygen supply during the bathing process by combining the characteristics of the human breathing area, the comfort requirements of air supply, and changes in human physiological parameters.

[0024] Example 1 In a typical embodiment of the present invention, such as Figure 1 and Figure 2 As shown, this embodiment discloses an integrated fresh air and oxygen supply system suitable for healthy showering, applicable to fields such as health and wellness, and healthy showering. The integrated fresh air and oxygen supply system includes: an air supply and oxygen supply device 1, an exhaust device, a human physiological parameter acquisition module, and a central control module; the air supply and oxygen supply device 1 is equipped with an integrated air outlet 2, the interior of which is divided vertically into three independent air supply channels, each corresponding to a different human breathing zone height; the air supply and oxygen supply device 1 is positioned opposite the exhaust device, forming a directional airflow channel in the shower room from the air supply side to the exhaust side; the central control module is connected to each functional module and configured to control the air supply and oxygen supply device 1 to provide directional air and oxygen supply to the corresponding breathing zone height according to preset parameters or human physiological parameters acquired by the human physiological parameter acquisition module.

[0025] In this embodiment, the air supply and oxygenation device 1 is installed in the wall of the shower room and includes a fresh air inlet 7, a filter device 8, an oxygen supply device 6, an oxygen mixing and regulating unit 9, a blower 11, and an integrated air outlet 2. The filter device 8 is located at the fresh air inlet 7. Fresh air enters the air supply and oxygenation device 1 through the fresh air inlet 7 located at the bottom or side of the device, undergoes preliminary filtration by the filter device 8 to remove particulate matter and impurities from the air, and then enters the oxygen mixing and regulating unit 9. In this embodiment, the oxygen mixing and regulating unit 9 is connected to the oxygen supply device 6 via an oxygen delivery pipeline. The oxygen supply device 6 can be a household oxygen generator, providing the oxygen source for the oxygen mixing and regulating unit 9. The filtered fresh air and oxygen are mixed in the oxygen mixing and regulating unit 9 according to a preset ratio to form a mixed air with adjustable oxygen concentration. The oxygen mixing and regulating unit 9 allows the system to replenish oxygen to the air supply system when needed. The mixed air enters the air supply fan 11, which powers the air supply and delivers it upwards to the air supply duct. The speed of the air supply fan 11 is adjusted by the central control module to control the air supply volume.

[0026] In this embodiment, the integrated air outlet 2 on the air supply and oxygenation device 1 is a single integrated air outlet, and three independent air supply channels are formed vertically within the single integrated air outlet: a high-level air supply channel 17, a middle-level air supply channel 18, and a low-level air supply channel 19. These three independent air supply channels correspond to the high-level breathing area, the middle-level breathing area, and the low-level breathing area, respectively. The high-level air supply channel 17, the middle-level air supply channel 18, and the low-level air supply channel 19 are respectively equipped with a first electric air valve 14, a second electric air valve 15, and a third electric air valve 16. The first electric air valve 14, the second electric air valve 15, and the third electric air valve 16 are independent of each other and controlled by a central control module. By controlling the first electric air valve 14, the second electric air valve 15, or the third electric air valve 16, the corresponding air supply channel is opened and closed, thereby achieving directional air supply and oxygenation for different human breathing area heights.

[0027] As a further implementation, a temperature regulation module is provided downstream of the air supply fan 11. This temperature regulation module includes a PTC electric heater 12 and an air supply temperature sensor 13. The PTC electric heater 12 is used to heat or maintain the temperature of the air supply, and the air supply temperature sensor 13 is used to detect the air supply temperature and feed the detection signal back to the central control module, thereby realizing closed-loop regulation of the air supply temperature and preventing low-temperature air from being blown directly onto the human body.

[0028] In this embodiment, the exhaust device includes an exhaust vent 3 and an exhaust fan 4 connected thereto. The exhaust vent 3 is located on the side wall of the shower room away from the air supply and oxygen supply device 1. By being positioned opposite to the air supply and oxygen supply device 1, a directional airflow channel from the air supply side to the exhaust side is formed in the shower room, which can promptly exhaust the high-humidity air generated during bathing to the outside, and together with the air supply and oxygen supply device 1, form a stable air circulation system to achieve a continuous replenishment of fresh air or oxygen-enriched air.

[0029] In this embodiment, the human physiological parameter acquisition module includes a wearable physiological parameter monitoring device worn by the user. This device establishes a data connection with the central control module and sends the collected human physiological parameters to the central control module. The central control module controls the operation of the air supply and oxygenation device 1 based on the received physiological parameters. As a further implementation, the wearable physiological parameter monitoring device can be a smart bracelet, used to collect the user's heart rate parameters during bathing and transmit these parameters to the central control module wirelessly.

[0030] In this embodiment, the central control module integrates a system startup logic unit, an air supply height and air volume control logic unit, an air supply temperature comfort control logic unit, and a human physiological risk enhancement control logic module. These logic units coordinate and control the various functional modules of the system to achieve automatic control mode. Specifically, the air supply height and air volume control logic module determines the air supply channel and basic air supply volume; the air supply temperature comfort control logic module adjusts the air supply temperature in real time using a continuous closed-loop method; and the human physiological risk enhancement control logic module intervenes when it detects that the user's physiological parameters meet preset conditions, enhancing oxygen supply to the air supply system. These control logic modules operate independently in automatic control mode, but are coordinated and managed by the central control module to achieve comprehensive regulation of air supply height, air volume, temperature, and oxygen supply status. In automatic control mode, after initialization and startup via the system startup logic module, the central control module simultaneously runs the air supply height and volume control logic module, the air supply temperature comfort control logic module, and the human physiological risk enhancement control logic module. Based on the user's input height parameters, it calculates and classifies the height of the human breathing zone and selects the corresponding air supply channel and basic air supply volume accordingly. At the same time, the central control module monitors and adjusts the air supply temperature in real time to maintain it within the preset comfort temperature range. When the user's physiological parameters are detected to meet the preset risk assessment conditions, the central control module, while maintaining the air supply height and temperature control strategies unchanged, activates the oxygen supply function to enhance the oxygen supply to the airflow.

[0031] In this embodiment, the system also includes an intelligent control panel 5 installed inside or outside the shower room, which is electrically connected to the central control module. Through the intelligent control panel 5, the user can input human height parameters, providing the central control module with parameter basis for calculating the height of the human breathing zone and making zoning judgments. In addition, the intelligent control panel 5 can realize the manual control mode of this system. In the manual control mode, the central control module pauses the automatic control logic based on human height and physiological parameters. The user can independently select the air supply channel, set the air supply volume and air supply temperature through the intelligent control panel 5, and choose whether to turn on the oxygen supply function. When the air supply temperature set by the user exceeds the safe range allowed by the system, the central control module restricts the relevant parameters and issues a prompt message to the user to ensure safe use.

[0032] Example 2 In a typical embodiment of the present invention, such as Figure 3 As shown, this embodiment discloses a control method for an integrated fresh air and oxygen supply system suitable for healthy showers. This control method is applicable to manual control mode and specifically includes: (1) The user enters the manual control mode through the intelligent control panel 5. The central control module receives the manual control mode command issued by the user through the intelligent control panel 5 and pauses the human height recognition logic and physiological risk enhancement control logic in the automatic control mode.

[0033] (2) Air supply channel selection: The air supply channel selection interface is displayed through the intelligent control panel 5. The user can select to open the high-level air supply channel 17, the medium-level air supply channel 18 or the low-level air supply channel 19.

[0034] (3) Perform air supply channel control. The central control module controls the electric air valve of the corresponding air supply channel to open and close the air supply channel that was not selected, based on the selection result.

[0035] (4) Air supply volume setting: The air supply volume setting interface is displayed on the intelligent control panel 55, and the user can manually set the target air supply volume. Target air supply volume It should be within the system's allowable air volume range, which should be determined based on the actual situation.

[0036] (5) Air supply volume execution: The central control module executes the air supply volume according to the target air supply volume. Turn on the supply fan 11 and the exhaust fan, and adjust the speed of the supply fan 11 so that the air supply system operates according to the target air volume.

[0038] (7) Safety judgment of supply air temperature, based on the target supply air temperature manually set by the user. Determine the target supply air temperature Whether it is within the system's permissible safe temperature range (the safe temperature range is determined based on experiments and human comfort studies, (But not limited to this range). If within the safe temperature range, proceed to step (8); if outside the safe temperature range, proceed to step (9).

[0039] (8) Supply air temperature execution: The central control module executes the supply air temperature according to the target supply air temperature. The operating status of the PTC electric heater 12 in the temperature regulation module is controlled to stabilize the supply air temperature at the target supply air temperature. nearby.

[0040] (9) Temperature limit and prompt: The central control module limits the target air supply temperature that exceeds the safe range and outputs prompt information to the user through the intelligent control panel 5, and then returns to step (6).

[0041] (10) Oxygen supply function selection: The oxygen supply function selection interface is displayed on the intelligent control panel 5, and the user can select to turn the oxygen supply function on or off.

[0042] (11) When the oxygen supply function is activated, the oxygen supply device 6 is activated, so that oxygen enters the oxygen mixing adjustment unit 9 through the oxygen delivery pipe 10 and is mixed with fresh air before entering the air supply system; if the oxygen supply function is deactivated, the oxygen supply device 6 is deactivated and the system only provides fresh air.

[0043] (12) Mode switching judgment: If a mode switching instruction is received, switch to automatic control mode and the process ends; if no mode switching instruction is received, maintain the current manual control operation state.

[0044] Example 3 In a typical embodiment of the present invention, such as Figures 4 to 6 As shown, this embodiment discloses another control method for an integrated fresh air and oxygen supply system suitable for healthy showers. This control method is applicable to automatic control mode and specifically includes: (1) Turn on the automatic control mode switch through the intelligent control panel 5, and the user inputs the human height through the intelligent control panel 5. The central control module first determines the height of the human body based on the preset height. The recognition results, through Calculate the current user's breathing zone height, where, This is the ratio of the height of the breathing area to the height of the human body. It can be preset based on a large amount of ergonomic experimental data, such as .

[0045] (2) Based on the current user's breathing zone height The central control module divides the human breathing area into zones and, based on the determination, controls the opening of the electric air valves in the integrated air outlet 2 that correspond to the height of the current user's breathing area. The remaining air outlets are closed or kept at minimum opening, thus concentrating the airflow primarily on the area around the user's mouth and nose, creating a stable airflow circulation within the shower room. Specifically: If the current user's breathing zone height Not exceeding the first height boundary value ,Right now If the current user is in the low breathing zone, open the third electric air valve 16 and close the other air valves; If the current user's breathing zone height Greater than the first height boundary value And not exceeding the second altitude boundary value ,Right now If the current user is in the mid-breathing zone, open the second electric air valve 15 and close the other air valves; If the current user's breathing zone height Greater than the second height boundary value ,Right now If the user is in the high breathing zone, open the first electric air valve 14 and close the other air valves.

[0046] Among them, the first altitude boundary value Second height boundary value A fixed height threshold, and the first height boundary value. Less than the second height boundary value These are used to divide the low, middle, and high respiratory regions, respectively. First height boundary value. Second height boundary value The height of the respiratory region can be determined based on statistical results of a large number of people of different ages, genders, and heights while standing and bathing, such as the first height cutoff value. Set at 1.4m, the second height dividing value. Set to 1.6m.

[0047] (3) Based on the current breathing zone, determine the corresponding target air volume and adjust the speed of the air supply fan 11: If the current breathing area is the low breathing area, adjust the speed of the supply fan 11 to make the air volume according to... Air is supplied through the low-level air supply channel 19; If the current breathing zone is the mid-breathing zone, adjust the speed of the supply fan 11 to adjust the air volume according to... Air is supplied through the central air supply channel 18; If the current breathing zone is a high breathing zone, adjust the speed of the supply fan 11 to adjust the air volume according to... Air is supplied through the high-level air supply channel 17.

[0048] in, , and The basic air supply volumes for the low-level air supply channel 19, the middle-level air supply channel 18, and the high-level air supply channel 17 are respectively determined by experiments.

[0049] As a further implementation, the method also includes a supply air temperature comfort monitoring and control step, specifically including: (1) Real-time monitoring of supply air temperature .

[0050] (2) Based on real-time supply air temperature The comfort level of the supply air temperature is assessed, and corresponding controls are implemented based on the assessment results. If the real-time supply air temperature The lowest temperature threshold below the comfortable supply air temperature range ,Right now The central control module determines that there is a risk of cold air blowing directly, and starts the PTC electric heater 12 in the temperature regulation module to heat the airflow. If the real-time supply air temperature The lowest temperature threshold within the comfortable supply air temperature range The highest temperature threshold of the comfortable air supply temperature range Between, that is The central control module determines that the current air supply temperature is within the comfortable range and controls the temperature regulation module to maintain a constant working state, so that the air supply system continues to operate at the current temperature.

[0051] If the real-time supply air temperature The highest temperature threshold above the comfortable air supply temperature range ,Right now The central control module determines that there is a risk of overheating in the air supply, so it controls the PTC electric heater 12 in the temperature regulation module to reduce the heating power, and gradually reduces the air supply temperature to a comfortable range through natural ventilation of the air supply system.

[0052] Among them, the lowest temperature threshold of the comfortable air supply temperature range This indicates the minimum permissible temperature at which the airflow will not cause cold stimulation to the human body in a bathing environment. This temperature can be determined based on experiments and human comfort studies, and can be adjusted within a preset range, such as by setting... The highest temperature threshold in the comfortable air supply temperature range. This indicates the maximum permissible temperature of the supplied airflow without causing stuffiness or affecting breathing comfort. It can be determined based on experiments and human comfort studies, and can be adjusted within a preset range, such as by setting... .

[0053] As a further implementation method, a human physiological risk monitoring and control step is also included, specifically including: (1) Real-time monitoring of the user's heart rate during the bathing process and heart rate variability .

[0054] (2) Based on the user's real-time heart rate during the bathing process and heart rate variability Assess the user's physiological risk status and adjust the air supply and oxygenation accordingly based on the assessment results: If the user's real-time heart rate greater than the preset safe heart rate threshold Or the user's real-time heart rate change rate greater than the preset heart rate change safety threshold When one of the above conditions is met, the user is determined to be in a state of increased physiological risk. At this time, the central control module controls the oxygen supply device 6 to start while maintaining the current air supply height and air supply temperature control strategy. This allows oxygen to enter the oxygen mixing and regulating unit 9 through the oxygen supply pipe 10, mix with fresh air, and then enter the air supply system to enhance the oxygen supply capacity of the human breathing area and reduce the burden on the human cardiopulmonary system.

[0055] Among them, the preset safe heart rate threshold and preset heart rate variability safety threshold It can be determined through experiments.

Users can manually set the target air supply temperature according to their personal comfort needs, and control the working state of the PTC electric heater in the temperature regulation module according to the target air supply temperature to keep the air supply temperature stable near the target air supply temperature. When the target air supply temperature set by the user exceeds the safe temperature range allowed by the system, the target air supply temperature is limited, and a prompt message is sent to the user through the intelligent control panel to prevent the user from experiencing discomfort or safety risks due to excessively low or high air supply temperatures.

7. The control method for an integrated fresh air and oxygen supply system suitable for healthy showers as described in claim 6, characterized in that, Also includes: The system provides users with an oxygen supply function selection interface, allowing them to choose whether to turn the oxygen supply function on or off. When the user chooses to turn on the oxygen supply function, the system controls the oxygen generator to start, allowing oxygen to enter the oxygen mixing and regulating unit through the oxygen delivery pipe, mix with fresh air, and then be sent to the air supply system. When the user chooses to turn off the oxygen supply function, the central control module controls the oxygen generator to stop working, and the system only provides fresh air to the air supply system.

8. A control method for an integrated fresh air and oxygen supply system suitable for healthy showers, characterized in that, include: Calculate the current user's breathing zone height based on the user's input height; Based on the current user's breathing zone height, the central control module divides the human breathing zone into zones. If the current user's breathing zone height does not exceed the first height boundary value, the current user is in the low breathing zone, the third electric air valve is opened, and the remaining air valves are closed. If the current user's breathing zone height is greater than the first height boundary value but does not exceed the second height boundary value, the current user is in the middle breathing zone, the second electric air valve is opened, and the remaining air valves are closed. If the current user's breathing zone height is greater than the second height boundary value, the current user is in the high breathing zone, the first electric air valve is opened, and the remaining air valves are closed. Based on the current breathing zone, determine the corresponding target air volume and adjust the air supply fan speed to deliver air.

9. The control method for an integrated fresh air and oxygen supply system suitable for healthy showers as described in claim 8, characterized in that, It also includes air supply temperature comfort monitoring and control steps, specifically including: Real-time monitoring of supply air temperature; The comfort level of the supply air temperature is assessed based on the real-time supply air temperature, and corresponding controls are implemented based on the assessment results. If the real-time supply air temperature is lower than the lowest temperature threshold of the comfortable supply air temperature range, it is determined that there is a risk of cold air blowing directly, and the temperature regulation module is activated to heat the supply airflow. If the real-time supply air temperature is between the lowest temperature threshold and the highest temperature threshold of the comfortable supply air temperature range, it is determined that the current supply air temperature is in the comfortable range, and the temperature regulation module is controlled to maintain a constant working state so that the supply air system continues to operate at the current temperature. If the real-time supply air temperature is greater than the highest temperature threshold of the comfortable supply air temperature range, it is determined that there is a risk of overheating in the supply air. The temperature regulation module is controlled to reduce the heating power, and the supply air temperature is gradually reduced to the comfortable range through natural ventilation of the supply air system.

10. The control method for an integrated fresh air and oxygen supply system suitable for healthy showers as described in claim 8, characterized in that, It also includes steps for monitoring and controlling human physiological risks, specifically including: Real-time monitoring of the user's heart rate and heart rate variability during the bathing process; The user's physiological risk status is determined based on their real-time heart rate and heart rate variability during the bathing process, and the air supply and oxygenation are controlled accordingly based on the assessment results. If the user's real-time heart rate is greater than the preset safe heart rate threshold, or the user's real-time heart rate change rate is greater than the preset safe heart rate change rate threshold, the user is determined to be in a state of increased physiological risk when one of the above conditions is met. Under the premise of maintaining the current air supply height and air supply temperature control strategy unchanged, the oxygen supply device is activated, so that oxygen enters the oxygen mixing adjustment unit through the oxygen delivery pipe, mixes with fresh air and enters the air supply system to enhance the oxygen supply capacity of the human breathing area.
