Description

Technical Field

[0001] The present invention relates to the technical field of health care instruments, and particularly relates to a moxibustion device and a control method thereof. Background Art

[0002] Moxibustion therapy is a treatment method that generates heat and smoke by burning moxa sticks at specific parts of the human body to stimulate and achieve the purpose of preventing and treating diseases. At present, the moxibustion device cannot accurately control the temperature of the fumigation chamber and cannot judge whether the moxa stick has burned out, resulting in that users cannot adjust the fumigation temperature according to personal needs and cannot end moxibustion in time. Moreover, the structure design of the fumigation cover of the moxibustion device is simple and single, which cannot meet the needs of moxibustion on multiple parts of the human body. Especially when moxibustion is carried out on parts such as the neck, elbow joint, and knee joint, it is easy to have smoke leakage, reducing the moxibustion effect and polluting the environment. The patent application "A Moxibustion Device" (201711348985.7) discloses a moxibustion device with convenient ignition and automatic temperature adjustment. However, the fumigation cover adopted by this patent cannot be applied to different parts of the human body. The ignition coil of this device is arranged at the bottom of the moxa stick, making the burning surface of the moxa stick gradually move away from the fumigation chamber during the moxibustion process and in the opposite direction to the air inlet direction, which is not conducive to the burning of the moxa stick. In addition, the controller of this device is connected to the moxibustion device, making the operation inconvenient.

[0003] In addition, the existing moxibustion devices cannot reasonably control the intake air and the flow of smoke, resulting in insufficient smoke concentration in the fumigation chamber, or the smoke flowing out of the moxibustion device without flowing through the skin surface, reducing the moxibustion effect. Moreover, the smoke flows out of the moxibustion device without treatment, polluting the environment. The patent application "A Moxibustion Device Facilitating Cleaning" (201810989647.X) discloses a moxibustion device that is easy to disassemble and clean. However, the combustion chamber structure of this device easily causes part of the side surface of the moxa stick to fit with the inner wall of the combustion chamber, resulting in uneven burning of the moxa stick. In addition, the smoke emission of this moxibustion device requires an additional connection to a smoke collection device, making it inconvenient to use. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: to provide a control method for a moxibustion device that is convenient to use and has a good moxibustion effect.

[0008] The inner wall of the combustion chamber is provided with a number of evenly distributed limiting protrusions for limiting the position of the moxa stick, and the bottom of the combustion chamber shell is provided with an air outlet;

[0009] The fumigation chamber comprises a fumigation chamber shell, a diverter plate is arranged in the inner cavity at the upper end of the fumigation chamber shell, and the diverter plate and the fumigation chamber shell form a buffer cavity; a fumigation hood is arranged at the lower end of the fumigation chamber shell, and a smoke exhaust cavity is formed between the inverted L-shaped lower edge of the fumigation chamber shell and the L-shaped upper edge of the fumigation hood, and a fumigation cavity is formed after the fumigation hood is attached to the skin, and a temperature sensor is arranged in the fumigation cavity;

[0010] A plurality of bottom air holes are arranged in the area corresponding to the diverter plate on the middle part of the outer shell of the fumigation chamber, a plurality of circumferentially evenly distributed side air holes are arranged in the area corresponding to the periphery of the diverter plate on the outer shell of the fumigation chamber, and an exhaust hole connected with the delayed discharge cavity is arranged on the outer shell of the fumigation chamber; a cover-shaped air dispersion portion protruding toward the fumigation hood is arranged on the diverter plate, a plurality of bottom air holes are arranged on the bottom surface of the air dispersion portion, and a plurality of side air holes are arranged on the side surface of the air dispersion portion; a plurality of top air holes are arranged in the area corresponding to the smoke discharge cavity on the fumigation hood, and the bottom of the fumigation hood is a fitting edge, and the fitting edge curve is designed according to different fumigation parts of the human body, and its curve equation is,

[0011]

[0012] The curve parameter p 00 、p 10 、p 01 、p 20 、p 11 、p 02 , p1, p2, p3 select corresponding data according to the different parts of the body that need moxibustion;

[0013] The control panel includes a moxibustion device control module and a remote controller control module;

[0014] The moxibustion device control module includes a wireless communication module and a power supply. The moxibustion device control module controls the start and stop of the ignition device, controls the start and stop and speed of the air pump motor, reads the temperature sensor parameters, and controls the display of temperature, power and usage status;

[0015] The remote control module includes a wireless communication module and a power supply. The remote control module reads the control button instructions and realizes the temperature display and power display functions;

[0016] The moxibustion device control module and the remote control module realize the transmission of control instructions and status information through the wireless communication module;

[0017] The control method specifically includes the following steps:

[0018] Step 1: Start the moxibustion device

[0019] Long press the switch on the touch panel. After waiting for 2 s, the moxibustion device starts to prevent accidental activation. After the moxibustion device starts, it waits for a remote control signal instruction. When the wireless communication module receives the start instruction, the ignition device and the air pump start. After the ignition device starts, it lasts for 5 s to ensure that the moxa stick is ignited. Then the ignition device turns off, and the air pump runs continuously in the gentle wind mode, that is, the air pump speed is 200 - 500 r / min, so that the temperature maintained in the fumigation chamber is lower than the temperature of normal moxibustion.

[0020] Step 2: Temperature setting

[0021] The touch panel collects the temperature data of the fumigation chamber in real time through the temperature sensor. The touch panel displays the temperature on the temperature display screen. At the same time, the touch panel sends the temperature data to the remote control through the wireless communication module, and the remote control displays the temperature on the display screen. The user adjusts the temperature through the remote control according to the moxibustion effect of the current temperature in the fumigation chamber, and the remote control sends the temperature data set by the user to the moxibustion device.

[0022] Step 3: Calculate the temperature difference Te

[0023] When the control module of the moxibustion device receives the set temperature data sent by the remote control, the control board reads the data of the temperature sensor 88 to obtain the actual temperature Tr in the current fumigation chamber. According to the set temperature value Tt of the remote control, the temperature difference e = T r -T t ;

[0024] Step 4: Adjust the air pump speed

[0025] According to the current temperature difference e, control the air pump speed, and use the pulse width modulation (PWM) mode to control the speed of the air pump motor. The value V of PWM k is calculated using the incremental PID algorithm;

[0026] V k = V k-1 + d Vk

[0027] where, V k is the current control output, V k-1 is the previous control output,

[0028] d Vk = K p × (e - e1)+ K i × e + K d × (e - 2e1 + e2)

[0029] where, e1 is the previous error value, e2 is the error value of the time before last time, K p is the proportional term coefficient, K pThe value range is 0.8 to 1.2, K i is the integral term coefficient, K i The value range is 0.8 to 1.2, K d is the differential term coefficient, K d The value range is 0.4 to 0.6;

[0030] Step 5: Determine the combustion state

[0031] When the temperature sensor detects that the temperature in the fumigation chamber drops, the control module will automatically increase the air pump speed to raise the temperature in the fumigation chamber. If the actual temperature Tr in the fumigation chamber does not increase or drops at this time, it means that the moxa stick is about to burn out, and the control board will issue a prompt for the end of moxa stick combustion to prompt the user to end the moxibustion.

[0032] As a preferred solution, the curve parameter value ranges of the fitting edge at the neck are respectively:

[0033] P 00 The value range is (104.5, 105.1), p 10 The value range is (-0.0004022, 0.0004022), p 01 The value range is (-0.000345, 0.000345), p 20 The value range is (0.003416, 0.003777), p 11 The value range is (-1.37e-05, 1.37e-05), p 02 The value range is (-0.005826, -0.005695), the value range of p1 is (-0.007438, 0.007438), the value range of p2 is (-0.2462, 0.2462), and the value range of p3 is (-13.89, 13.89).

[0034] As a preferred solution, the curve parameter value of the fitting edge at the neck is: p 00 = 104.8, p 10 = -5.134e-17, p 01 = -1.613e-16, p 20 = 0.003596, p 11 = 2.948e-18, p 02 = -0.00576, p1 = 5.049e-21, p2 = 8.237e-18, p3 = 6.967e-17.

[0035] As a preferred solution, the ignition device includes a sealed housing, an ignition module, and a ceramic sheet. The sealed housing is circumferentially provided with a power supply interface for the ignition module, the circumferential bottom of the sealed housing is equipped with a double-layer sealing ring, a gas inlet hole is provided circumferentially, and an air outlet hole of the ignition device is provided in the middle of the ceramic sheet;

[0036] As a preferred solution, the end face of the gas inlet hole of the ignition device contacts the inner inclined surface of the gas inlet hole of the touch panel and is sealed through a gas inlet sealing ring. The bottom periphery of the ignition device is inserted into the combustion chamber;

[0037] As a preferred solution, the combustion chamber includes an inner combustion chamber housing and an outer combustion chamber housing. A sealing limit ring groove is provided on the outer wall of the inner combustion chamber housing, a sealing ring is installed in the sealing limit ring groove, a number of evenly distributed limit convex bumps are provided on the outer wall of the outer combustion chamber housing, a sealing lip is provided at the bottom of the outer combustion chamber housing, and a sealing ring is installed on the sealing lip;

The lip of the fumigation hood fits closely with parts such as the human knee joint, elbow joint, and neck, reducing flue gas leakage and improving the moxibustion effect;

[0041] This method for controlling the temperature of the fumigation chamber meets the fumigation chamber temperature requirements of different users. Through precise control of the air pump, the effect of moxibustion fumigation is better. BRIEF DESCRIPTION OF THE DRAWINGS

The inner combustion chamber shell 41 is provided with limit protrusions to avoid the problem of incomplete combustion caused by the contact between the moxa stick and the inner wall of the inner combustion chamber shell 41;

[0066] The fumigation chamber 8 includes an outer fumigation chamber shell 81. A flow dividing plate 82 is installed in the upper inner cavity of the outer fumigation chamber shell 81. The flow dividing plate 82 and the outer fumigation chamber shell 81 enclose a buffer chamber 85; The flow dividing plate 82 is used to control the flow direction of the smoke, so that the smoke enters the fumigation chamber 86 through the buffer chamber 85 or enters the fumigation chamber from all around, avoiding the direct flow of the smoke to the skin and causing burns. The smoke circulates in the fumigation chamber 86, making the smoke closely contact the skin and improving the moxibustion effect;

[0067] The lower end of the fumigation chamber housing 81 is equipped with a fumigation hood 83. A flue gas discharge chamber 87 is formed between the inverted L-shaped lower edge of the fumigation chamber housing 81 and the L-shaped upper edge of the fumigation hood 83, and an activated carbon packet 84 is installed in the flue gas discharge chamber 87.

[0068] A number of bottom air holes 811 are provided in the upper middle part of the fumigation chamber housing 81 corresponding to the flow dividing plate 82, a number of circumferentially evenly distributed side air holes 812 are provided in the area of the fumigation chamber housing 81 corresponding to the periphery of the flow dividing plate 82, and an exhaust hole 813 communicating with the delayed discharge chamber is provided on the fumigation chamber housing 81; a cover-shaped air dispersion part protruding towards the fumigation hood 83 is provided on the flow dividing plate 82, a number of bottom air holes 821 are provided on the bottom surface of the air dispersion part, and a number of side air holes 822 are provided on the side surface of the air dispersion part; a number of top air holes 831 are provided in the area of the fumigation hood 83 corresponding to the flue gas discharge chamber 87, and the bottom of the fumigation hood 83 is a fitting edge 832,

[0069] The curve of the fitting edge 832 of the fumigation hood 83 is designed according to different fumigation parts of the human body, and its curve equation is,

[0070]

[0071] where the curve parameters p 00 、p 10 、p 01 、p 20 、p 11 、p 02 、p1, p2, p3 select corresponding data according to different parts where moxibustion is required. Taking the neck as an example, the value ranges of the curve parameters of the fitting edge are as follows:

[0073] As Figure 14 shown, the internal air flow direction of the moxibustion device is as described below.

[0074] S1: The air provided by the air pump 6 enters the inner cavity of the ignition device 1 through the air inlet hole 25 of the touch panel 2 and the air inlet hole 14 of the ignition device 1;

[0075] S2: The air enters the inner cavity of the combustion chamber 4 through the air outlet hole 15 of the ignition device;

[0076] S3: In the inner cavity of the combustion chamber 4, the air passes through the burning surface of the moxa stick to form moxa stick burning smoke;

[0077] S4: The smoke passes through the air outlet hole 43 of the inner shell 41 of the combustion chamber and enters the upper cavity of the fumigation chamber 8;

[0078] S5: The smoke passes through the air hole 821 in the middle of the flow dividing plate 82, enters the buffer cavity 85, and then enters the fumigation cavity 86 through the air hole 811;

[0079] S6: The smoke flows around through the flow dividing plate 82 and enters the fumigation cavity 86 through the side air holes 822 of the flow dividing plate 82 and the side air holes 812 of the outer shell 81 of the fumigation chamber;

[0080] S7: The smoke circulates in the fumigation cavity 86 and makes full contact with the skin;

[0081] S8: The excess smoke in the fumigation cavity 86 flows into the flue gas treatment cavity 87 through the top air hole 831 of the fumigation hood 83;

[0082] S9: The smoke in the flue gas treatment cavity 87 flows through the activated carbon package 84, and after being absorbed and treated, it is discharged to the outside of the moxibustion instrument through the exhaust hole 813 of the outer shell 81 of the fumigation chamber.

[0083] As Figure 15 shown, the control board includes a moxibustion device control module and a remote control module; the independent remote control is convenient to control. The flue gas treatment device is built into the moxibustion device, and there is no need to externally connect a flue gas collection and treatment device, which is convenient to use;

[0084] The moxibustion device control module includes a wireless communication module and a power supply. The moxibustion device control module controls the start and stop of the ignition device, controls the start and stop and speed of the air pump motor, reads the parameters of the temperature sensor, and controls the display of temperature, power, and usage status;

[0085] The remote control module includes a wireless communication module and a power supply. The remote control module reads the operation button instructions and realizes the functions of temperature display and power display;

[0086] The control module of the moxibustion device and the remote control module achieve the transmission of control instructions and status information through the wireless communication module.

[0087] As Figure 16 shown, the control method of the moxibustion device specifically includes the following steps.

[0088] Step 1: Start the moxibustion device

[0089] Long press the switch 21 on the touch panel 2, and wait for 2 s before the moxibustion device starts to prevent accidental activation; after the moxibustion device starts, wait for the remote control signal instruction. When the wireless communication module receives the start instruction, the ignition device and the air pump start. After the ignition device starts, it lasts for 5 s to ensure that the moxa stick is lit, and then the ignition device is turned off. The air pump runs continuously in the gentle wind mode, that is, the air pump speed is 200 - 500 r / min, so that the temperature maintained in the fumigation chamber is lower than the temperature of normal moxibustion.

[0090] Step 2: Temperature setting

[0091] The touch panel collects the temperature data of the fumigation chamber in real time through the temperature sensor. The touch panel displays the temperature on the temperature display screen. At the same time, the touch panel sends the temperature data to the remote control through the wireless communication module, and the remote control displays the temperature on the display screen. The user adjusts the temperature through the remote control according to the moxibustion effect of the current temperature in the fumigation chamber, and the remote control sends the temperature data set by the user to the moxibustion device.

[0092] Step 3: Calculate the temperature difference Te

[0093] When the control module of the moxibustion device receives the set temperature data sent by the remote control, the control board reads the data of the temperature sensor 88 to obtain the actual temperature Tr in the current fumigation chamber. According to the temperature value Tt set by the remote control, calculate the temperature difference e = T r -T t ;

[0094] Step 4: Adjust the air pump speed

[0095] According to the current temperature difference e, control the air pump speed, and use the pulse width modulation (PWM) mode to control the air pump motor speed. The value V of PWM k is calculated using the incremental PID algorithm;

[0096] V k = V k-1 +d Vk

[0097] where V k is the current control output, V k-1 is the previous control output,

[0098] dVk = K p ×(e - e1) + K i ×e + K d ×(e - 2e1 + e2)

[0099] Wherein, e1 is the previous error value, e2 is the error value of the time before last, and K p is the proportional term coefficient, and K p ranges from 0.8 to 1.2, and K i is the integral term coefficient, and K i ranges from 0.8 to 1.2, and K d is the differential term coefficient, and K d ranges from 0.4 to 0.6;

[0100] Step 5: Determine the combustion state

[0101] When the temperature sensor detects a temperature drop in the fumigation chamber, the control module will automatically increase the air pump speed to raise the temperature of the fumigation chamber. If the actual temperature Tr in the fumigation chamber does not increase or decreases at this time, it indicates that the moxa stick is about to burn out, and the control board will issue a prompt for the end of moxa stick combustion to prompt the user to end the moxibustion.

[0102] The above embodiments only illustratively explain the principle and efficacy of the present invention and some applied embodiments, rather than limiting the present invention; it should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
