The cleaned smoke and dust particles automatically fall to the inner side of the dust collecting trough 205 under the action of their own gravity for collection. The support plate 204 can be rotated to release the limit of the dust collecting trough 205. After the dust collecting trough 205 is removed from the outside of the ash discharge pipe 202, the smoke and dust particles collected on the inside of the dust collecting trough 205 are cleaned.
