Smoke filtering efficiency detection method, fan speed regulation method, circuit, moxibustion instrument and medium

Abstract

The invention discloses a smoke filtering efficiency detection method, a fan speed regulation method, a circuit, a moxibustion instrument and a medium, wherein the smoke filtering efficiency detectionmethod comprises the following steps of carrying out the sampling on a drive current of a smoke suction fan, so as to obtain a first sampling signal; filtering the first sampling signal, and taking the filtered signal as a reference signal; carrying out periodical sampling on the driving current of the smoke suction fan after a first preset time interval; filtering the signal obtained by samplingeach time, and taking the filtered signal as a to-be-detected signal; and comparing the to-be-detected signal with the reference signal. When the difference value between the to-be-detected signal and the reference signal is greater than a first threshold value, the smoke filtering efficiency is reduced. According to the smoke filtering efficiency detection method, the smoke filtering efficiencyof a smoke filter is judged by acquiring the changes of the driving current of the smoke suction fan, so that whether the smoke filter adsorbs excessive smoke particles or not is judged, automatic speed regulation of the smoke suction fan and reminding of replacement of the smoke filter in the subsequent process are facilitated, and the automation degree of the moxibustion instrument is improved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a smoke filtering efficiency detection method, a fan speed regulation method, a circuit, a moxibustion instrument and a medium. Background technique [0002] Moxibustion is a treatment method that uses the moxibustion material made of mugwort leaves to stimulate acupuncture points or specific parts on the body surface, and adjust the disordered physiological and biochemical functions of the human body by stimulating the activity of meridian qi, so as to achieve the purpose of disease prevention and treatment. . However, in the process of moxibustion, the burning of mugwort leaves will produce a lot of smoke, which is directly discharged into the air. First, it will harm people who have been moxibustion for a long time, and second, it will also cause certain pollution to the environment. Therefore, moxibustion instruments Most of them are provided with smoking structures....
