The high-pressure air pipe 11 can be connected with an external high-pressure air pump, so that high-pressure gas can enter the jet port 12 through the high-pressure air pipe 11; after the end of the holding cylinder 1 provided with the jet port 12 is inserted into the flue 5, the high-pressure gas will be sprayed onto the inner wall of the flue 5 through the jet port 12, achieving preliminary cleaning of the soot.
[0025] The motor 2 is installed on the holding cylinder 1, and the output shaft of the motor 2 is connected to the brush head 3. The motor 2 can drive the brush head 3 to rotate, and the brush head 3 is coaxially arranged with the flue 5 during rotation and can be rotatably abutted against the inner wall of the flue 5, so as to brush off the soot attached to the inner wall of the flue 5.
[0026] It is worth noting that the jet port 12 is directed towards the edge of the brush head 3, so that the soot brushed off by the brush head 3 is separated from the inner wall of the flue 5 and the brush head 3, improving the cleaning effect of the soot and avoiding the influence of the cleaning effect of the brush head 3 on other soot due to the attachment of a large amount of soot on the brush head 3.
[0027] The motor 2 is connected with a cable 21 for connecting an external power source, the cable 21 is arranged on the inner side of the holding cylinder 1, ensuring normal power supply of the motor 2 and avoiding the attachment of soot on the cable 21 as much as possible.
[0028] In this embodiment, the diameter of the flue 5 is 70 cm, the length of the flue 5 is 5.5 m, and the diameter of the brush head 3 is 65-70 cm, so as to ensure the cleaning effect of the brush head 3 on the inside of the flue 5 and facilitate the entry and exit of the brush head 3 into the flue 5.
[0029] Example 2
