[0029] In order to facilitate understanding of the above technical solution of the present invention, the working principle or operation method of the present invention in the actual process is described in detail below.

[0030] In actual application, when it is necessary to clean the dust adhering to the heating surface of the water pipe, the dual-axis motor 11 and the motor are started, and the motor drives the screw rod 10 to rotate. The limit slider 3 slides in the slideway 2 as the screw rod 10 rotates, thereby driving the turntable 6, the ring 7 and the cleaning brush 9 to move left and right, and the dual-axis motor 11 drives the rotating shaft 5 and the rotating shaft 17 to rotate, and the rotating shaft 5 drives the gear 1 12 and the turntable 6 to rotate.

At the same time, when the cleaning brush 9 moves up and down, it is also helpful to shake off the dust.

[0031] To sum up, with the help of the above-mentioned technical scheme of the utility model, through the coordinated design of the turntable 6, the ring 7 and the cleaning brush 9 with the driving assembly, it is possible to automatically clean the dust covering the heated surface of the water pipe, so as to effectively clean the dust, thereby not only improving the efficiency of dust cleaning, but also reducing the labor intensity of the staff; and the coordinated design of the pulley 19 and the wave-shaped slide groove 20 enables the pulley 19 to continuously push the movable block 4 up and down during the rotation process, so that the cleaning brush 9 can not only clean the water pipe when moving horizontally, but also clean the water pipe along with the up and down movement. At the same time, when the cleaning brush 9 moves up and down, it is also beneficial to shake off the dust.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
