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, including sampling the driving current of the smoking fan to obtain a first sampling signal; and filtering the first sampling signal process, and use the filtered signal as a reference signal; after the first preset time interval, periodically sample the driving current of the smoking fan; filter the signal obtained each time, and use the filtered signal as The signal to be tested; the signal to be tested is compared with the reference signal, and when the difference between the signal to be tested and the reference signal is greater than a first threshold, the smoke filtering efficiency decreases. By obtaining the change of the driving current of the smoking fan, the smoke filtering efficiency of the smoke filter is judged, so as to judge whether the smoke filter absorbs too many smoke particles, so as to facilitate the automatic speed regulation of the smoking fan and remind to replace the smoke filter. It is beneficial to improve the degree of automation of the moxibustion instrument.

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....

Problems solved by technology

However, during use, as the use time increases, more and more smoke particles will be adsorbed on the smoke filter, resulting in worse and worse smoking effect
