[0048] The core of the present invention is to provide a temperature controller and a therapeutic device. The water inlet pipe continuously fills the heating pot with water, which can avoid a sudden drop in temperature due to adding too much cold water at one time. The power of the heating pot and the fan speed of the corresponding area are adjusted according to the temperature of each area to make the temperature of each area equal, thereby improving the user experience.

[0049] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0050] Figure 1 A schematic diagram of the structure of a temperature controller provided by the present invention, Figure 2 A flow chart of the steps executed by a temperature controller provided by the present invention, Figure 3 A schematic diagram of the structure of a therapeutic device provided by the present invention;

[0051] The present invention provides a temperature controller 1, which is arranged in a therapeutic apparatus. The therapeutic apparatus also includes a heating pot 2 and a steam bin 3. The steam bin is divided into N areas. Each area includes a fan 31 and a temperature detection module 32. The heating pot is used to heat the internal liquid. The fan is used to blow the water vapor after the internal liquid is heated into the corresponding area of ​​the steam bin.

[0052] The therapeutic effect of traditional Chinese medicine fumigation is that the heat energy of fumigation and the drugs carried by steam interact and act together on the human body. The drug ions produced in the traditional Chinese medicine steam are used to directly fumigate the skin or patients, so as to dredge the meridians, harmonize the qi and blood, remove the toxins in the skin, and cure the disease. At present, in the era of intelligent and humanized development of medical equipment, cabin fumigation products have complex structures, large volumes, and high power. In this complex environment inside the cabin, it is particularly difficult to achieve uniform temperature distribution in the fumigation cabin due to the different weights and heights of each patient. The problem of low user satisfaction is becoming increasingly prominent.

[0053] The existing cabin fumigation therapy equipment includes bed type, seat type and space capsule type. The fumigation device is designed as a whole with the acrylic shell. The installation method of the fumigation steam generator is different according to the style. In order to improve the patient experience, the cabin fumigation product is designed with zoned temperature control to control different parts of the human body. Figure 2 For example, the internal space of the fumigation chamber is divided into zone A, zone B, and zone C with independent temperature control methods, and fumigation treatment is carried out on the head, neck, waist, and legs of the human body.

[0054] The water and medicine are heated in the heating pot to become steam, and the fan blows the steam into the steam chamber, where the user receives treatment.

[0055] The temperature controller includes:

[0056] A memory 11, used for storing computer programs;

[0057] The processor 12 is used to implement the following steps when executing the computer program:

[0058] S21: obtaining the actual height of the liquid inside the heating pot;

[0059] S22: When the actual height is not equal to the set height, the flow rate of the water inlet pipe for filling the heating pot with water is controlled according to the actual height and the set height, and the water inlet pipe continuously fills the heating pot with water;

[0060] Considering that in the related art, the heating pot is not filled with water until the actual height of the internal liquid is low, it is understandable that the heating pot is often filled with cold water. The cold water will lower the temperature of the heating pot, resulting in a lower temperature of the water vapor blown to the steam bin by the fan. The user will feel a sudden drop in temperature in the steam bin, which is a poor experience.

[0061] Therefore, the water inlet pipe in the present application continuously fills the heating pot with water. When the actual height is not equal to the set height, the flow rate of the water inlet pipe filling the heating pot with water is adjusted to ensure that the actual height is equal to the set height. Since the water inlet pipe is continuously filled with water, a large amount of cold water will not be suddenly filled into the heating pot, and the temperature of the heating pot will not drop suddenly, which provides a better user experience.

[0062] S23: Acquire the temperatures of N areas sent by N temperature detection modules in N areas, where N is a positive integer;

[0063] S24: controlling the power of the heating pot according to the temperatures of the N zones, wherein the power of the heating pot is positively correlated with the temperatures of the N zones;

[0064] Due to the large volume of the steam warehouse, the steam warehouse is divided into N areas. The temperature detection module in each area will obtain the temperature of the area. If the temperature of each area is too high, it proves that the power of the current heating pot is too large, which may easily scald the user, and the power should be lowered; if the temperature of each area is too low, it proves that the power of the current heating pot is too low, the user will feel cold, and the power should be increased.

[0065] Specifically, the temperature is adjusted by a PID (Proportional Integral Derivative) algorithm according to the temperature of each area and a preset target temperature.

[0066] S25: Controlling the rotation speeds of the N fans in a one-to-one correspondence according to the temperatures of the N zones and the preset temperature, so that the temperature of each zone is equal, and the rotation speed of the fan is positively correlated with the temperature of the zone corresponding to the fan.

[0067] Since the water vapor in the steam bin is blown in by the fan, the higher the fan speed, the more water vapor is blown in, and the higher the temperature in the steam bin; on the contrary, the lower the fan speed, the less water vapor is blown in, and the lower the temperature in the steam bin. Then, the PID algorithm is used to determine and control the fan speed according to the temperature of each area and the preset temperature, so that the temperature of each area is equal.

[0068] The present application provides a temperature control method, which relates to the field of temperature control, including obtaining the actual height of the internal liquid of the heating pot; when the actual height is not equal to the set height, controlling the flow rate of the water inlet pipe to fill the heating pot with water according to the actual height and the set height, and the water inlet pipe continuously fills the heating pot with water; obtaining the temperature of N areas sent by N temperature detection modules in N areas; controlling the power of the heating pot according to the temperature of the N areas; and controlling the speed of N fans one by one according to the temperature of the N areas and the preset temperature, so that the temperature of each area is equal. The water inlet pipe continuously fills the heating pot with water, which can avoid the sudden drop in temperature due to adding too much cold water at one time, and the water inlet flow rate can be adjusted according to the liquid height. At the same time, the power of the heating pot and the fan speed of the corresponding area are adjusted according to the temperature of each area so that the temperature of each area is equal, thereby improving the user experience.

[0069] Based on the above embodiments:

[0070] In some embodiments, the therapeutic apparatus further comprises a weighing sensor 4;

[0071] Get the actual height of the liquid inside the heating pot in real time, including:

[0072] Get the total mass of the pot and the liquid inside sent by the load cell;

[0073] Determine the mass of the liquid inside based on the weight of the heating pot itself and the total mass;

[0074] The actual height is determined by the mass of the liquid inside and the volume of the heating pot.

[0075] In the related art, a liquid level sensor is used to measure the position of the liquid in the heating pot. However, during fumigation treatment, the hot water in the heating pot is in a boiling and tumbling state, and there is a large measurement error problem of the liquid level sensor. Therefore, the liquid level sensor of the heating pot is changed into a weighing sensor, and the weighing sensor data is collected and the mass of the heating pot is subtracted to obtain the liquid level weight. The actual height of the liquid in the heating pot is determined based on the volume in the heating pot, and the actual height obtained is more accurate.

[0076] In some embodiments, the therapeutic apparatus further comprises a solenoid valve 5, a control end of the solenoid valve is connected to the temperature controller, a first end of the solenoid valve is connected to the water inlet pipe, and a second end of the solenoid valve is connected to the heating pot;

[0077] Control the flow rate of water filling the heating pot according to the actual height and the set height, including:

[0078] The conduction angle of the solenoid valve is controlled according to the actual height and the set height.

[0079] Taking into account that the water inlet pipe continuously fills the heating pot with water, the amount of water inlet needs to be controlled by controlling the flow of the water inlet pipe. A solenoid valve is set as a control element. If the conduction angle of the solenoid valve is larger, the water inlet volume is larger, and if the conduction angle is smaller, the water inlet volume is smaller, thereby realizing the control of the water flow.

[0080] It should also be noted that the element for controlling the water flow includes but is not limited to a solenoid valve, and may also be an element capable of limiting the flow, such as a flow control valve.

[0081] In some embodiments, after obtaining the actual height of the liquid inside the heating pot in real time, the method further includes:

[0082] When the actual height is not equal to the set height, determine whether the actual height is greater than the liquid level threshold;

[0083] If the liquid level is greater than the threshold, an alarm will be issued.

[0084] It should be noted that the set height must be lower than the overall height of the heating pot and at a height where water will not overflow, so if the actual height is equal to the set height, the current liquid will not overflow. If the actual height is not equal to the set height, if it is lower than the set height, the water flow needs to be increased, and if it is higher than the set height, the water flow needs to be reduced. At the same time, it is also necessary to determine whether it is higher than the liquid level threshold. If it is higher than the liquid level threshold, the liquid will overflow and an alarm needs to be issued so that the operation and maintenance personnel can handle it.

[0085] In some embodiments, controlling the power of the heating pot according to the temperatures of the N zones includes:

[0086] Determine the minimum value among the temperatures of N regions;

[0087] Perform PID to determine the power based on the minimum value;

[0088] The power of the heating pot is controlled according to the power.

[0089] Considering that there are N areas in the steam warehouse, the temperatures of each area may be unequal. If the highest temperature is used as the control standard, the area with lower temperature will not reach the preset temperature. If the lowest temperature is used as the control standard, the highest temperature will also reach the preset temperature to meet the needs of each area.

[0090] In some embodiments, after controlling the power of the heating pot according to the temperatures of the N zones, the method further includes:

[0091] Determine whether it is in preheating mode;

[0092] If it is in the preheating mode, the electric heater is controlled to turn on so that the temperature of the steam chamber reaches the preset temperature.

[0093] In some embodiments, after determining whether the system is in the preheating mode, the method further includes:

[0094] If it is not in the preheating mode, determine whether it is in the treatment mode;

[0095] If it is in the treatment mode, the process enters the step of controlling the rotation speeds of the N fans in a one-to-one correspondence between the temperatures of the N zones and the preset temperatures.

[0096] In some embodiments, after controlling the rotation speeds of the N fans in a one-to-one correspondence between the temperatures of the N zones and the preset temperatures, the method further includes:

[0097] Control the hot water in the heating pot to be output to the steam chamber and control the start of the electric heater.

[0098] First is the preheating stage, the electric heater is running and the heating pot is heated up, press the start button to preheat, at this time the drug liquid in the heating pot is not boiling, the temperature in the fumigation chamber is low, and the steam chamber is heated mainly by the heat of the electric heater, waiting for the temperature of the electric heater to gradually rise, the power of the electric heater to gradually decrease, until it stops completely, the preheating stage is completed, the program jumps to the heating pot PID temperature control treatment stage, collects data from the three temperature sensors in the steam chamber, performs fuzzy PID temperature control operations in the corresponding space, adjusts the fan speed, reduces the heat convection and conduction environmental conditions caused by the sealing and internal structure space in the steam chamber, and provides patients with a good treatment environment; finally, after the fumigation is completed, the program executes the water flushing and electric heater drying stages, and the heating pot stops heating. Due to the long fumigation time and the high temperature in the chamber, the body sweats and eliminates toxins in the body. The shower water column in the fumigation chamber washes away these dirt and drug residues. When the flushing is completed, the electric heater blows dry the water droplets on the body, giving the body a gradual cooling process to adapt to the room temperature environment.

[0099] That is, the therapeutic device of the present application includes three modes, a preheating mode, a treatment mode and a drying mode.

[0100] Figure 4 A flow chart of a PID algorithm provided by the present invention;

[0101] In some embodiments, the speeds of the N fans are controlled one-to-one according to the temperatures of the N zones and the preset temperature, including:

[0102] Determine the difference between the temperature of N areas and a preset temperature;

[0103] According to the N differences and the change rates of the differences, the N PID algorithm parameters Kp, Ki and Kd are determined one by one;

[0104] The fan speed is determined according to the one-to-one correspondence of the parameters Kp, Ki and Kd of the N PID algorithms;

[0105] The rotation of the fans is controlled in a one-to-one correspondence according to the rotation speeds of the N fans.

[0106] The traditional PID algorithm uses fixed parameters Kp, Ki and Kd. Although it can solve the problem of determining the fan speed and controlling the temperature stability, due to individual differences among users, the speed determination during the control process is not accurate enough. Therefore, the present application adopts a fuzzy PID algorithm, that is, the parameters Kp, Ki and Kd of the PID algorithm are determined based on the difference E between the temperature input of N regions and the preset temperature and the rate of change of the difference dE / dt. The fuzzy control output is determined based on the difference and the rate of change of the difference to obtain the parameters, and then the PID is used to determine the fan speed output, and then the fan rotation is controlled based on the obtained fan speed. The temperature after the fan is controlled to rotate is determined to be different from the preset temperature, so as to implement the temperature control.
