The moxa smoke passes through the metal filter screen 202 when flowing toward the smoke outlet 205. The moxa oil in the moxa smoke is liquefied by cold and collected in the oil collecting cavity 207 along the metal filter screen 202. The impurities (ashes and unburned moxa) in the moxa smoke are intercepted by the metal filter screen 202 and fall in the right cavity 209. Finally, the moxa smoke filtered by the metal filter screen 202 enters the left cavity 208 and flows toward the post-filtering device 3 through the smoke outlet 205.

[0027] It should be noted that the post-filtering device 3 is a conventional filtering device used in the existing moxa smoke purifier. The post-filtering device 3 is used to burn the remaining moxa in the moxa smoke at high temperature and discharge the high-temperature air after deodorization. Therefore, no further description is given herein.

Correspondingly, the moxa smoke enters the left cavity 208 from the smoke inlet 204 and flows toward the smoke outlet 205. The moxa smoke passes through the metal filter screen 202 when flowing toward the smoke outlet 205. The moxa oil in the moxa smoke is liquefied by cold and collected in the oil collecting cavity 207 along the metal filter screen 202. The impurities (ashes and unburned moxa) in the moxa smoke are intercepted by the metal filter screen 202 and fall in the left cavity 208. Finally, the moxa smoke filtered by the metal filter screen 202 enters the right cavity 209 and flows toward the post-filtering device 3 through the smoke outlet 205.
