Description

Technical Field

[0001] This invention relates to the field of negative oxygen ion therapy equipment technology, and in particular to a health and wellness bed with negative oxygen ion generation function and its control method. Background Technology

[0002] In the field of negative ion therapy equipment technology, as people's pursuit of a healthy and high-quality life continues to improve, the demand for health and wellness equipment that can create a healthy and comfortable environment is increasing day by day.

[0003] Currently, existing health and wellness beds have serious shortcomings in improving air quality before users lie down on them. In daily life, indoor air quality is easily affected by various factors, such as the influx of polluted outdoor air, harmful gases released from furniture, and the accumulation of dust particles. When users enter the bedroom to rest, they often expect to quickly find themselves in an environment with significantly improved air quality, immediately experiencing the comfort of fresh air. However, most existing health and wellness beds lack the ability to improve air quality when the user is not using them. Summary of the Invention

[0004] To address the technical problems existing in the prior art, this invention provides a health and wellness bed with negative oxygen ion generation function and a control method thereof.

[0005] The technical solution adopted in this invention is:

[0007] The control box has a built-in main controller, which is connected to the negative oxygen ion generating module, temperature and humidity control module, bed board tilt adjustment mechanism, air quality monitoring module, exhaust module and human body status monitoring module respectively.

[0008] The bed frame includes a bed board, and the bed board tilt adjustment mechanism is connected to the bed board;

[0009] The negative ion generating module includes a high-pressure negative ion generator, a low-pressure negative ion generator, an eco-grade negative ion chip, and an airflow guiding component. The high-pressure negative ion generator and the low-pressure negative ion generator are arranged at intervals along the length of the bed and are both connected to the bed space through the airflow guiding component. The eco-grade negative ion chip is integrated into the inner wall of the airflow channel of the airflow guiding component.

[0010] Preferably, the temperature and humidity control module includes a humidification outlet, which is located on one side of the bed.

[0011] Preferably, the temperature and humidity control module further includes a heating strip, which is disposed on one side of the bed.

[0012] Preferably, the bed board tilt adjustment mechanism includes an electric push rod and an angle sensor, the electric push rod being hinged to the bed board, and the angle sensor being used to detect the tilt angle of the bed board.

[0013] Preferably, the human body status monitoring module includes a heart rate sensor, a respiratory rate sensor, and a body motion sensor, which are respectively connected to the main controller.

[0014] Preferably, the airflow guiding assembly includes adjustable guide vanes.

[0015] Preferably, the ventilation module includes an exhaust vent and a fan. The exhaust vent is located on the side or bottom of the bed and is used to exhaust air from the bed space. The fan is connected to the main controller.

[0016] Preferably, the bed board is made of a material that generates negative oxygen ions.

[0017] The second aspect of this application provides a method for controlling a health and wellness bed with negative oxygen ion generation function, including the following steps:

[0018] Step 1: The main controller receives a pre-start command. Based on the pre-start command, the main controller obtains the first temperature parameter, the first humidity parameter, the first PM2.5 concentration parameter, and the first negative oxygen ion concentration parameter through the air quality monitoring module. The pre-start command includes the pre-start time and the start duration.

[0019] Step 2: The main controller generates a first temperature and humidity adjustment command and a first negative oxygen ion concentration parameter adjustment command based on the first temperature parameter, the first humidity parameter, the first PM2.5 concentration parameter, the first negative oxygen ion concentration parameter, and the start-up duration.

[0020] Step 3: Based on the first temperature and humidity adjustment command, the temperature and humidity control module adjusts the temperature and humidity; based on the first negative oxygen ion concentration parameter adjustment command, the negative oxygen ion generating module adjusts the negative oxygen ion concentration.

[0021] Step 4: The main controller obtains the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter through the air quality monitoring module;

[0022] Step 5: The main controller determines whether the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions. If the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions, then step 6 is executed.

[0023] Step 6: Maintain the working status of the temperature and humidity control module and the negative oxygen ion generation module, and start the exhaust device. Through the temperature and humidity control module, the negative oxygen ion generation module, and the exhaust device, maintain the second temperature parameter, the second humidity parameter, and the second negative oxygen ion concentration parameter to meet the preset conditions.

[0024] Preferably, step 6 is followed by the following steps:

[0025] Step 7: The human body status monitoring module detects whether the user is lying on the bed. When the human body status monitoring module detects that the user is lying on the bed, the main controller obtains the user's heart rate, respiratory rate and body movement data through the human body status monitoring module, and obtains the tilt angle of the bed board through the bed board tilt adjustment mechanism.

[0026] Step 8: The main controller generates a second temperature and humidity adjustment command and a second negative oxygen ion concentration parameter adjustment command based on the user's heart rate, respiratory rate and body movement data, the tilt angle of the bed board and the second negative oxygen ion concentration parameter.

[0027] Step 9: Based on the second temperature and humidity adjustment command, the temperature and humidity control module adjusts the temperature and humidity; based on the second negative oxygen ion concentration parameter adjustment command, the negative oxygen ion generating module adjusts the negative oxygen ion concentration.

[0028] The beneficial effects of this invention are at least one of the following: By acquiring indoor air quality parameters such as air temperature, air humidity, PM2.5 concentration, and negative oxygen ion concentration in real time and accurately through the air quality monitoring module, the indoor air quality can be accurately monitored. Based on this, the high-voltage negative ion generator, low-voltage negative ion generator, and eco-grade negative ion chip in the negative oxygen ion generating module work together to generate a stable and high concentration of negative oxygen ions. Before the user lies down on the bed, the air is purified in advance, removing dust, and adjusting temperature, humidity, and negative oxygen ion concentration, quickly creating a fresh environment throughout the bed space.

[0029] The human body status monitoring module's heart rate sensor, respiratory rate sensor, and body movement sensor collect the user's heart rate, respiratory rate, and body movement data in real time, accurately determining the user's awakeness, sleep, and other states. Once the user lies down on the bed, the main controller generates secondary temperature and humidity adjustment commands and secondary negative oxygen ion concentration parameter adjustment commands based on this data and the bed's tilt angle, providing a personalized health and wellness environment tailored to the user's condition and meeting their health needs in different states.

[0034] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0035] Example 1 provides a health and wellness bed with negative oxygen ion generation function, such as... Figure 1 As shown, it includes a bed body 1, a control box 2, a negative oxygen ion generating module 3, a temperature and humidity control module 4, a bed board tilt adjustment mechanism 5, an air quality monitoring module 6, an exhaust module 7, and a human body status monitoring module 8.

[0036] The control box 2 houses the main controller 21, such as Figure 2 As shown, the main controller 21 is connected to the negative oxygen ion generating module 3, the temperature and humidity control module 4, the bed board tilt adjustment mechanism 5, the air quality monitoring module 6, the exhaust module 7, and the human body status monitoring module 8, respectively.

[0037] The bed frame 1 includes a bed board 11, and the bed board tilt adjustment mechanism 5 is connected to the bed board 11;

[0038] The negative ion generating module 3 includes a high-pressure negative ion generator 31, a low-pressure negative ion generator 32, an eco-grade negative ion chip (not shown), and an airflow guiding component 33. The high-pressure negative ion generator 31 and the low-pressure negative ion generator 32 are arranged at intervals along the length of the bed body 1 and are both connected to the bed body space through the airflow guiding component 33. The eco-grade negative ion chip (not shown) is integrated into the inner wall of the airflow channel of the airflow guiding component 33.

[0039] In the specific implementation process, such as Figure 1 As shown, the bed frame 1 is the main structure of the entire health and wellness bed, providing a platform for users to rest. The bed frame 1 includes a bed board 11, which is made of a negative ion-generating material that continuously releases negative ions. Working in conjunction with the negative ion generating module 3, it further increases the concentration of negative ions in the bed space, enhancing the health and wellness effect. The control box 2 is located on one side of the bottom of the bed frame 1 and houses the main controller 21. The main controller 21 serves as the core control unit of the entire health and wellness bed. Through a wireless communication module, it transmits data and interacts with the negative ion generating module 3, the temperature and humidity control module 4, the bed board tilt adjustment mechanism 5, the air quality monitoring module 6, the ventilation module 7, and the human body status monitoring module 8, achieving unified control of each module.

[0040] High-pressure negative ion generator 31 and low-pressure negative ion generator 32 are arranged at intervals along the length of bed 1, located at both ends of bed 1. This arrangement can generate negative oxygen ions from different locations, expanding the generation range of negative oxygen ions and allowing them to be more evenly distributed within the bed space.

[0041] Both the high-pressure negative ion generator 31 and the low-pressure negative ion generator 32 are connected to the bed space via the airflow guiding assembly 33. The outer shell of the airflow guiding assembly 33 is made of antistatic and corrosion-resistant materials, and the internal eco-grade negative ion chip is integrated into the inner wall of the airflow channel, which can further improve the generation efficiency and quality of negative oxygen ions. The airflow guiding assembly 33 includes adjustable guide vanes 331. Adjusting the angle of the guide vanes 331 adjusts the diffusion direction of negative oxygen ions, ensuring that negative oxygen ions can evenly cover the entire bed space, providing users with a fresh environment rich in negative oxygen ions.

[0042] The temperature and humidity control module 4 is located between the high-pressure negative ion generator 31 and the low-pressure negative ion generator 32, facilitating coordinated operation with the negative oxygen ion generation module. The temperature and humidity control module 4 includes a humidification outlet 41 and a heating strip 42. The humidification outlet 41 is located on one side of the bed 1, and a humidifier (not shown) is connected inside it. When the main controller 21 determines that humidity needs to be increased based on the humidity data fed back by the air quality monitoring module 6, it sends a command to the humidifier via wireless communication to start the humidifier, releasing water vapor into the bed space through the humidification outlet 41 to regulate air humidity.

[0043] Heating strip 42 is also located on one side of the bed frame 1 and is made of high-efficiency heating materials, such as ceramic heating elements. When the main controller 21 determines that heating is needed based on temperature data, it controls the operating power of heating strip 42 via wireless communication to generate heat and raise the temperature of the bed space. The heating power of heating strip 42 can be steplessly adjusted according to actual needs to achieve precise temperature control.

[0044] The bed board tilt adjustment mechanism 5 includes an electric push rod 51 and an angle sensor 52. One end of the electric push rod 51 is hinged to the frame of the bed body 1, and the other end is hinged to the bed board 11. The tilt angle of the bed board 11 is changed by its extension and retraction. The angle sensor 52 is installed at the connection between the bed board 11 and the bed body 1. It is used to detect the tilt angle of the bed board 11 in real time and to feed back the angle information to the main controller 21 in real time via wireless communication.

[0045] For example, a user can send a bed tilt adjustment command to the main controller 21 via a control panel (not shown), a mobile app, or other input devices. Upon receiving the command, the main controller 21 sends a control signal to the electric actuator 51 via wireless communication, based on the target tilt angle specified in the command, to control the extension and retraction of the electric actuator 51. During the movement of the electric actuator 51, the angle sensor 52 monitors the tilt angle of the bed board 11 in real time and feeds the angle data back to the main controller 21 via wireless communication. The main controller 21 compares the feedback angle data with the target tilt angle and continuously adjusts the control signal of the electric actuator 51 until the bed board 11 reaches the target tilt angle. Once the bed board 11 reaches the target tilt angle, the main controller 21 controls the electric actuator 51 to maintain its current state, thus ensuring a stable tilt of the bed board 11.

[0046] For example, the air quality monitoring module 6 includes a PM2.5 concentration sensor, a negative oxygen ion concentration sensor, and a temperature and humidity sensor. The PM2.5 concentration sensor is used to detect the concentration of particulate matter with a diameter of less than or equal to 2.5 micrometers in the air, the negative oxygen ion concentration sensor is used to detect the concentration of negative oxygen ions in the air, and the temperature and humidity sensor is used to detect the temperature and humidity parameters of the bed space.

[0047] For example, the exhaust module 7 includes an exhaust vent 71 and a fan 72. The exhaust vent 71 is located on the side or bottom of the bed frame 1 and is used to exhaust stale air from the bed space. The fan 72 is a low-noise, high-pressure centrifugal fan and is wirelessly connected to the main controller 21. The exhaust module 7 can also work in conjunction with the negative ion generating module 3 and the temperature and humidity control module 4. During ventilation, the negative ion generating module 3 continuously generates negative ions. As fresh air enters, the negative ions diffuse more quickly throughout the bed space, improving air freshness and negative ion concentration. Simultaneously, the temperature and humidity control module 4 adjusts the humidification or heating functions in a timely manner according to changes in air temperature and humidity during ventilation, maintaining the temperature and humidity within the bed space within a comfortable range.

[0048] In a specific implementation, after the main controller 21 receives a pre-start command including the pre-start time and start duration, it sends a data acquisition command to the air quality monitoring module 6 via wireless communication. The PM2.5 concentration sensor, negative oxygen ion concentration sensor, and temperature and humidity sensor in the air quality monitoring module 6 respond rapidly, respectively detecting the concentration of particulate matter with a diameter less than or equal to 2.5 micrometers in the air, the concentration of negative oxygen ions, and the temperature and humidity parameters of the bed space in real time. They acquire the first temperature parameter, the first humidity parameter, the first PM2.5 concentration parameter, and the first negative oxygen ion concentration parameter, and then feed these data back to the main controller 21 via wireless communication.

[0049] Based on the received parameters and the start-up duration, the main controller 21 generates a first temperature and humidity adjustment command and a first negative oxygen ion concentration parameter adjustment command. For example, if the first temperature parameter is lower than the lower limit of the preset comfortable temperature range and the start-up duration is 1 hour, the main controller 21 calculates, based on the heating efficiency of the heating strip 42 and the heat exchange situation of the bed space, that the power of the heating strip 42 needs to be gradually increased over the next half hour to bring the temperature to the comfortable range within 1 hour; if the first negative oxygen ion concentration parameter is much lower than the target concentration, the main controller 21 calculates, based on the performance parameters of the high-voltage negative ion generator 31 and the low-voltage negative ion generator 32, that the operating voltage of the high-voltage negative ion generator 31 needs to be increased and the operating current of the low-voltage negative ion generator 32 needs to be increased within the first 20 minutes after start-up to quickly increase the negative oxygen ion concentration.

[0050] The main controller 21 sends the first temperature and humidity adjustment command to the temperature and humidity control module 4 via wireless communication. Upon receiving the command, if the command requests an increase in humidity, the main controller 21 sends a start command to the humidifier, which then begins operation, releasing water vapor into the bed space through the humidification outlet 41 to regulate air humidity. If the command requests a temperature increase, the main controller 21 controls the operating power of the heating strip 42 to generate heat and raise the temperature of the bed space. The heating power of the heating strip 42 can be steplessly adjusted according to actual needs to achieve precise temperature control. Simultaneously, the main controller 21 sends the first negative oxygen ion concentration parameter adjustment command to the negative oxygen ion generating module 3. The high-voltage negative ion generator 31 and the low-voltage negative ion generator 32 in the negative oxygen ion generating module 3 adjust their operating states according to the command, generating more negative oxygen ions. The ecological-grade negative ion chip further improves the generation efficiency and quality of negative oxygen ions, enabling negative oxygen ions to cover the entire bed space.

[0051] After a preset time, the main controller 21 again sends a data acquisition command to the air quality monitoring module 6 via wireless communication to obtain the second temperature parameter, second humidity parameter, second PM2.5 concentration parameter, and second negative oxygen ion concentration parameter. The main controller 21 judges these parameters. If the second temperature parameter, second humidity parameter, second PM2.5 concentration parameter, and second negative oxygen ion concentration parameter all meet the preset conditions, such as temperature between 22-25℃, humidity between 40%-60%, PM2.5 concentration below 35 micrograms / cubic meter, and negative oxygen ion concentration between 2000-5000 ions / cubic centimeter, the air in the bed space is in a clean and high-quality state rich in therapeutic components. At this time, the main controller 21 maintains the current working state of the negative oxygen ion generating module 3, continuously maintaining the negative oxygen ion concentration within the ideal range. Since a certain amount of excess air is generated during the purification process, the main controller 21 controls the exhaust module 7 to start, and the fan 72 to operate, so that this excess air is discharged from the gaps in the bed (i.e., the exhaust port 71). During the exhaust process, the negative ion generating module 3 continuously operates, replenishing negative ions to ensure that the air quality within the bed space remains consistently high. Simultaneously, the temperature and humidity control module 4, based on temperature and humidity data fed back from the air quality monitoring module 6, uses the main controller 21 to fine-tune the power of the heating strip 42 or implement other temperature and humidity regulation measures in real time to maintain stable temperature and humidity within a comfortable range.

[0052] In one possible implementation, the human body status monitoring module 8 includes a heart rate sensor 81, a respiratory rate sensor 82, and a body motion sensor 83, which are respectively connected to the main controller.

[0053] Among them, such as Figure 1 As shown, the heart rate sensor 81, respiratory rate sensor 82, and body motion sensor 83 are integrated inside the bed board 11. Flexible sensor technology can be used to make it conform to the curve of the human body. For example, the heart rate sensor 81 can be a millimeter-wave radar sensor, the respiratory rate sensor 82 can be a piezoelectric respiratory sensor, and the body motion sensor 83 can be a gyroscope sensor.

[0054] In the specific implementation process, the human body status monitoring module 8 works continuously. The heart rate sensor 81 (millimeter-wave radar sensor), respiratory rate sensor 82 (piezoelectric respiratory sensor), and body motion sensor 83 (gyroscope sensor) integrated inside the bed board 11 use flexible sensor technology to conform to the curves of the human body, monitor the user's heart rate, respiratory rate, and body motion data in real time, and transmit these data to the main controller 21 via wireless communication. At the same time, the angle sensor 52 detects the tilt angle of the bed board 11 in real time and feeds the angle information back to the main controller 21.

[0055] When the system detects that a user is lying on the bed, the main controller 21 generates a second temperature and humidity adjustment command and a second negative oxygen ion concentration parameter adjustment command based on the user's heart rate, respiratory rate, body movement data, the bed board's tilt angle, and the current negative oxygen ion concentration parameter using a specific algorithm. For example, if the user's heart rate is fast, respiratory rate is slightly high, and body movement is frequent, it is determined that the user may be in a relatively active state. In this case, if the negative oxygen ion concentration parameter is below 2000 ions / cm³, the main controller 21 generates a command to appropriately increase the negative oxygen ion concentration, while simultaneously adjusting the temperature by reducing the power of the heating strip 42. If the user's heart rate is low, respiratory rate is stable, and body movement is infrequent, it is determined that the user is in a sleep state. In this case, if the negative oxygen ion concentration parameter is above 5000 ions / cm³, the main controller 21 generates a command to decrease the negative oxygen ion concentration, while simultaneously appropriately increasing humidity and adjusting the power of the heating strip 42 to maintain a suitable temperature.

[0056] The main controller 21 sends the second temperature and humidity adjustment command and the second negative oxygen ion concentration parameter adjustment command to the temperature and humidity control module 4 and the negative oxygen ion generation module 3, respectively. These two modules make corresponding adjustments according to the commands, thereby providing users with a personalized health and wellness environment.

[0057] Example 2 provides a method for controlling a health and wellness bed with negative oxygen ion generation function, including the following steps:

[0058] Step 1: The main controller receives a pre-start command. Based on the pre-start command, the main controller obtains the first temperature parameter, the first humidity parameter, the first PM2.5 concentration parameter, and the first negative oxygen ion concentration parameter through the air quality monitoring module. The pre-start command includes the pre-start time and the start duration.

[0059] Step 2: The main controller generates a first temperature and humidity adjustment command and a first negative oxygen ion concentration parameter adjustment command based on the first temperature parameter, the first humidity parameter, the first PM2.5 concentration parameter, the first negative oxygen ion concentration parameter, and the start-up duration.

[0060] Step 3: Based on the first temperature and humidity adjustment command, the temperature and humidity control module adjusts the temperature and humidity; based on the first negative oxygen ion concentration parameter adjustment command, the negative oxygen ion generating module adjusts the negative oxygen ion concentration.

[0061] Step 4: The main controller obtains the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter through the air quality monitoring module;

[0062] Step 5: The main controller determines whether the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions. If the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions, then step 6 is executed.

[0063] Step 6: Maintain the working status of the temperature and humidity control module and the negative oxygen ion generation module, and start the exhaust device. Through the temperature and humidity control module, the negative oxygen ion generation module, and the exhaust device, maintain the second temperature parameter, the second humidity parameter, and the second negative oxygen ion concentration parameter to meet the preset conditions.

[0064] In one possible implementation, step 6 is followed by the following steps:

[0065] Step 7: The human body status monitoring module detects whether the user is lying on the bed. When the human body status monitoring module detects that the user is lying on the bed, the main controller obtains the user's heart rate, respiratory rate and body movement data through the human body status monitoring module, and obtains the tilt angle of the bed board through the bed board tilt adjustment mechanism.

[0066] Step 8: The main controller generates a second temperature and humidity adjustment command and a second negative oxygen ion concentration parameter adjustment command based on the user's heart rate, respiratory rate and body movement data, the tilt angle of the bed board and the second negative oxygen ion concentration parameter.

[0067] Step 9: Based on the second temperature and humidity adjustment command, the temperature and humidity control module adjusts the temperature and humidity; based on the second negative oxygen ion concentration parameter adjustment command, the negative oxygen ion generating module adjusts the negative oxygen ion concentration.

[0068] Specifically, the main controller generates a second temperature and humidity adjustment command and a second negative oxygen ion concentration parameter adjustment command based on the user's heart rate, respiratory rate, body movement data, the tilt angle of the bed board, and the second negative oxygen ion concentration parameter. These commands include the following:

[0069] If the main controller detects through the human body status monitoring module that the user's heart rate is higher than the preset awake heart rate threshold, and the respiratory rate is higher than the preset awake respiratory rate threshold, and the number of body movements detected by the body movement sensor per unit time exceeds the preset active body movement number threshold, then the user is determined to be awake.

[0070] If the main controller detects through the human body status monitoring module that the user's heart rate is lower than the preset awake heart rate threshold, and the respiratory rate is lower than the preset awake respiratory rate threshold, and the number of body movements detected by the body movement sensor per unit time is lower than the preset number of active body movements threshold, then the user is determined to be in a sleep state.

[0071] When the user is determined to be awake and the bed tilt angle is less than or equal to a preset threshold, the body's metabolism is active in the awake state, requiring more negative oxygen ions to promote blood circulation and refresh the mind. When the bed tilt angle is ≤ the preset threshold (e.g., ≤ 30°), the user is usually in a semi-reclining or lying position. In this position, the respiratory tract is more open, increasing sensitivity to air quality. Increasing the concentration of negative oxygen ions can increase the oxygen content in the air, helping the user remain awake.

[0072] The main controller determines whether the second negative oxygen ion concentration parameter is less than the preset upper limit of negative oxygen ion concentration. If the second negative oxygen ion concentration parameter is less than the preset upper limit of negative oxygen ion concentration, it generates a command to increase the negative oxygen ion concentration. The main controller sends a command to the negative oxygen ion generating module 3 to increase the working power of the high-voltage negative ion generator 31 and the low-voltage negative ion generator 32, and at the same time adjusts the angle of the guide vanes 331 in the airflow guiding component 33 to make the negative oxygen ions diffuse more efficiently to the user's surroundings. For temperature and humidity regulation, the main controller makes a judgment based on the current second temperature parameter and second humidity parameter. If the temperature is higher than the upper limit of the comfortable temperature range, the main controller generates a command to reduce the power of the heating strip 42 and turn on the air cooling function, and increases the airflow speed by adjusting the fan speed adjustment device to accelerate air flow and reduce the perceived temperature. If the humidity is lower than the lower limit of the comfortable humidity range, the main controller sends a command to the temperature and humidity control module 4 to start the humidifier and increase the air humidity, but will dynamically adjust the humidification intensity according to the real-time humidity data to ensure that the humidity does not exceed the upper limit of the comfortable range.

[0073] In the above scheme, when the bed board tilt angle is small (such as 30°), the head position is low, and the active water mist generated by the humidifier forms particles with a diameter of <5μm under the action of negative oxygen ions, which can penetrate deep into the alveoli, improving the humidification effect compared to ordinary humidification methods.

[0074] If the second negative oxygen ion concentration parameter is greater than the preset upper limit of negative oxygen ion concentration, the main controller will maintain the current working state of the negative oxygen ion generating module 3. If the temperature is lower than the lower limit of the comfortable temperature range, the main controller will control the heating bar 42 to increase its power and raise the temperature of the bed space; if the humidity is higher than the upper limit of the comfortable humidity range, the exhaust volume of the exhaust module 7 will be increased to accelerate air circulation and reduce humidity.

[0075] When the user is determined to be asleep and the bed board tilt angle is greater than the preset threshold, the parasympathetic nervous system is active during sleep, and excessively high concentrations of negative oxygen ions (>5000 ions / cm³) may trigger nerve excitation. When the bed board tilt angle is greater than the preset threshold (e.g., >45°), the human body is in a semi-reclining position, and the respiratory system is more sensitive to airflow. Reducing the concentration can avoid irritating the respiratory tract.

[0076] The main controller also judges the second negative oxygen ion concentration parameter. If the second negative oxygen ion concentration parameter is greater than the preset lower limit of negative oxygen ion concentration, the main controller generates a command to appropriately reduce the negative oxygen ion concentration. The main controller sends a command to the negative oxygen ion generating module 3 to reduce the working power of the high-voltage negative ion generator 31 and the low-voltage negative ion generator 32, thereby reducing the amount of negative oxygen ions generated. In terms of temperature and humidity regulation, if the temperature is higher than the upper limit of the suitable temperature range for sleep, the main controller controls the heating strip 42 to reduce its power and appropriately increase the humidity, because a slightly higher humidity environment helps to improve sleep comfort during sleep. The main controller will start the humidifier and accurately adjust the humidification amount according to the real-time humidity data; if the temperature is lower than the lower limit of the suitable temperature range for sleep, the main controller controls the heating strip 42 to increase its power to maintain a warm sleep environment.

[0077] The embodiments described above are merely illustrative of specific implementations of the present invention, and while the descriptions are detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.

A method for controlling a health and wellness bed with negative oxygen ion generation function, characterized in that, Includes the following steps: Step 1: The main controller receives a pre-start command. Based on the pre-start command, the main controller obtains a first temperature parameter, a first humidity parameter, a first PM2.5 concentration parameter, and a first negative oxygen ion concentration parameter through the air quality monitoring module. The pre-start command includes a pre-start time and a start duration.

Step 5: The main controller determines whether the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions. If the second temperature parameter, the second humidity parameter, the second PM2.5 concentration parameter, and the second negative oxygen ion concentration parameter all meet the preset conditions, then step 6 is executed. Step 6: Keep the temperature and humidity control module and the negative oxygen ion generation module in working condition, start the exhaust device, and maintain the second temperature parameter, the second humidity parameter and the second negative oxygen ion concentration parameter to meet the preset conditions through the temperature and humidity control module, the negative oxygen ion generation module and the exhaust device. Following step 6, the following steps are also included: Step 7: The human body status monitoring module detects whether the user is lying on the bed. When the human body status monitoring module detects that the user is lying on the bed, the main controller obtains the user's heart rate, respiratory rate and body movement data through the human body status monitoring module, and obtains the tilt angle of the bed board through the bed board tilt adjustment mechanism. Step 8: The main controller generates a second temperature and humidity adjustment command and a second negative oxygen ion concentration parameter adjustment command based on the user's heart rate, respiratory rate and body movement data, the tilt angle of the bed board and the second negative oxygen ion concentration parameter. Step 9: Based on the second temperature and humidity adjustment command, the temperature and humidity control module adjusts the temperature and humidity; based on the second negative oxygen ion concentration parameter adjustment command, the negative oxygen ion generating module adjusts the negative oxygen ion concentration. If the main controller detects through the human body status monitoring module that the user's heart rate is higher than the preset awake heart rate threshold, and the respiratory rate is higher than the preset awake respiratory rate threshold, and the number of body movements detected by the body movement sensor per unit time exceeds the preset active body movement number threshold, then the user is determined to be awake. If the main controller detects through the human body status monitoring module that the user's heart rate is lower than the preset awake heart rate threshold, and the respiratory rate is lower than the preset awake respiratory rate threshold, and the number of body movements detected by the body movement sensor per unit time is lower than the preset number of active body movements threshold, then the user is determined to be in a sleep state. When the user is determined to be awake and the bed board tilt angle is less than or equal to the preset angle threshold, increasing the concentration of negative oxygen ions can enhance the oxygen content in the air and help the user stay awake.
