7. A moxibustion device according to any one of claims 1-3 wherein: and an activated carbon bag is arranged in the smoke discharge cavity.

8. The control method of the moxibustion device according to claims 1-7, comprising the following steps:

step 1: starting moxibustion device

Pressing a switch on the touch panel for a long time, waiting for 2s, and starting the moxibustion device to prevent the moxibustion device from being started by mistakenly touching; after the moxibustion device is started, waiting for a signal instruction of a remote controller, starting an ignition device and an air pump after a wireless communication module receives a start instruction, continuing for 5s after the ignition device is started to ensure that the moxa stick is ignited, then closing the ignition device, and continuously operating the air pump in a breeze mode, namely in a state that the rotating speed of the air pump is 200-500 r/min, so that the temperature kept by a fumigation cavity is lower than the temperature of normal moxibustion;

step 2: temperature setting

The temperature data of the fumigation cavity are collected by the touch panel in real time through the temperature sensor, the temperature is displayed on the temperature display screen by the touch panel, meanwhile, the temperature data are sent to the remote controller through the wireless communication module by the touch panel, the temperature is displayed on the display screen by the remote controller, the temperature is adjusted by a user through the remote controller according to the moxibustion effect of the current fumigation cavity temperature, and the temperature data set by the user are sent to the moxibustion device by the remote controller;

step 2: calculating the temperature difference Te

When moxibustion device control module receives the set temperature data sent by the remote controller, the control board reads the data of temperature sensor 88 to obtain the actual temperature Tr in the current fumigation cavity, and the temperature difference e is calculated as T according to the temperature value Tt set by the remote controller_r-T_t；

And step 3: adjusting the rotational speed of the air pump

Controlling the rotation speed of the air pump according to the current temperature difference e, and controlling the rotation speed of the motor of the air pump by using a Pulse Width Modulation (PWM) mode, wherein the value V of the PWM_kCalculating by adopting an incremental PID algorithm;

V_k＝V_k-1+d_Vk

wherein, V_kFor this control output, V_k-1In order to control the output in the last time,

d_Vk＝K_p×(e-e₁)+K_i×e+K_d×(e-2e₁+e₂)

wherein e is₁As last error value, e₂As last error value, K_pIs the coefficient of the proportional term, K_pThe value range is 0.8-1.2, K_iAs integral term coefficient, K_iThe value range is 0.8-1.2, K_dIs a coefficient of differential term, K_dThe value range is 0.4-0.6;

and 4, step 4: determining combustion state

When temperature sensor detected stifling intracavity temperature and dropped, control module can improve the air pump rotational speed automatically and promote stifling chamber temperature, if stifling intracavity actual temperature Tr did not increase or drop this moment, then explain that the moxa stick is about to burn and accomplish, the control panel then sends the moxa stick and burns the end suggestion, the suggestion of suggestion user's end moxa-moxibustion.
