[0097] The top of the purge cylinder 553 is rotatably connected to the connecting ring plate 552. The purge cylinder 553 is provided with a plurality of air holes. The purge cylinder 553 is a double-circle structure with inner and outer concentric circles.
[0098] The fan blade 3 554 is disposed inside the purge cylinder 553 and connected thereto;
[0099] A cleaning brush 555 is connected to the purge cylinder 553;
[0100] The major arc plate 556 is connected to the connecting ring plate 552 and is located between the double rings on one side close to the rotating cylinder 51 .
[0101] The lateral movement of the telescopic tube 535 drives the folded tube 551 to move laterally, so that the cleaning brush 555 abuts against the inner wall of the chimney, and part of the airflow enters the inside of the purge tube 553 through the folded tube 551. The airflow drives the fan blade three 554 to rotate, and the fan blade three 554 drives the purge tube 553 to rotate, thereby driving the cleaning brush 555 to rotate, and cleans the fine impurities on the inner wall of the chimney. At the same time, the airflow is blown out from the air holes on the purge tube 553 to purge the impurities, and the cleaning brush 555 is used to clean the inner wall of the chimney to achieve a better cleaning effect. The superior arc plate 556 limits the flow direction of the airflow to ensure that the outflow direction of the airflow is always toward the inner wall of the chimney, thereby ensuring the blowing strength of the airflow.
[0102] As an embodiment of the present invention, a soft cushion is provided on the impact ball 543 .
[0103] The soft cushion is provided to ensure that the impact ball 543 is in flexible contact with the inner wall of the chimney, thereby preventing the chimney from being damaged by the impact force.
[0104] The working principle of the present invention is as follows: the telescopic member 1 41 drives the sliding sleeve 42 to move longitudinally, the sliding sleeve 42 drives the support rod 1 43 to rotate, the support rod 1 43 drives the bracket 44 to rotate, and then drives the power wheel 45 to move, so that the power wheel 45 abuts against the inner wall of the chimney, the telescopic member 2 531 drives the connecting plate 532 to move downward, the connecting plate 532 drives the support rod 2 533 to rotate, and under the limit of the telescopic tube 535, drives the scraper 1 534 to move horizontally, so that the scraper 2 5371 and the chimney are in contact with each other. The scraper 2 5371 abuts against the inner wall of the chimney, and the elastic member 1 5372 ensures that the scraper 2 5371 is in flexible contact with the inner wall of the chimney. The blower 3 blows out airflow, and the airflow enters the interior of the rotating cylinder 51 through the connecting pipe 2, so that the fan blade 1 52 rotates, and the fan blade 1 52 drives the rotating cylinder 51 to rotate, and the rotating cylinder 51 drives the scraper 2 5371 to revolve, so as to scrape off the impurities adhering to the inner wall of the chimney, and part of the airflow enters the interior of the rotating tube 536 through the telescopic tube 535, so that the fan blade 2 541 rotates, and the fan blade 2 541 rotates. 41 drives the rotating tube 536 to rotate, and at the same time, the scraper 1 534 drives the rotating tube 536 to revolve. Under the action of centrifugal force, the impact ball 543 moves. During the rotation process, it collides with the inner wall of the chimney, generating vibration, reducing the adhesion between impurities and the inner wall of the chimney. The soft cushion arranged on the impact ball 543 ensures that the impact ball 543 is in flexible contact with the inner wall of the chimney to avoid damage to the chimney caused by the impact force. Part of the airflow enters the inside of the purge cylinder 553 through the folded tube 551, and the airflow drives the fan blade 3 554 to rotate. The fan blade 3 554 drives the purge cylinder 553 to rotate, and then drives the cleaning brush 555 to rotate to clean the fine impurities on the inner wall of the chimney. At the same time, the airflow is blown out from the air hole on the purge cylinder 553, and the cleaning brush 555 is used to clean the inner wall of the chimney. The superior arc plate 556 limits the flow direction of the airflow to ensure that the outflow direction of the airflow is always toward the inner wall of the chimney. The movement of the power wheel 45 drives the movement of the device to achieve comprehensive cleaning of the inner wall of the chimney.
