[0023] In this embodiment, a sealing ring 6 is installed on the side of the blocking plate 3, an ear handle 4 is installed on the bottom of the blocking plate 3, and a first slide groove 5 is opened at the bottom of the installation groove 7. The width of the first slide groove 5 is equal to the width of the ear handle 4.

[0024] Through the above structure, the width of the first slide groove 5 is set to be the same as the width of the ear handle 4. When the ear handle 4 is pushed to slide toward the inside of the first slide groove 5, the sealing plate 3 can be driven to retract to the inside of the installation groove 7. At this time, the first spring 8 is compressed and the opening 2 is opened. This design is for daily cleaning of the flue pipe 1 to discharge the dirt cleaned from the inside of the flue pipe 1 from the opening 2. When the ear handle 4 is released, the sealing plate 3 slides toward the outside of the installation groove 7 under the action of the rebound force of the first spring 8 to close the opening 2. The sealing ring 6 installed on the side of the sealing plate 3 ensures the sealing performance at the opening 2, avoids smoke leakage pollution to the flue pipe 1, and improves the practicality of the utility model.

[0025] In this embodiment, the notches are symmetrically arranged on the upper and lower sides and the left and right sides of the structure box 91, and the upper and lower notches and the left and right notches are staggered.

[0026] Through the above structure, the four slots are staggered on the structural box 91, and the driving rollers 93 are also staggered on the structural box 91, so that the structural box 91 has four supporting points in the moving direction, and the four supporting points are staggered, so that the structural box 91 always remains parallel to the moving direction, and the cleaning ability of the cleaning brush 92 on the outside of the structural box 91 is guaranteed.

[0027] In this embodiment, a slider 95 is fixedly installed on the side of the bracket 94, and a second slide groove 96 is opened at the position of the structural box 91 corresponding to the slider 95. The slider 95 is slidably connected to the second slide groove 96, and the bracket 94 is a U-shaped frame.

[0028] Through the above structure, the second slide groove 96 opened on the inner side of the structural box 91 is slidably connected to the slider 95, so that the slider 95 slides inside the second slide groove 96, providing a guide for the bracket 94, and providing a guide track for the displacement direction of the driving roller 93.

[0029] In this embodiment, the driving roller 93 is rotatably mounted on a bracket 94, a motor 99 is mounted on the inner side of the bracket 94, a gear 910 is mounted on the output end of the motor 99, a toothed disc is mounted on the side of the driving roller 93, the toothed disc is meshed with the gear 910, two telescopic rods 97 are fixedly connected between the two brackets 94, a second spring 98 is sleeved on the outer side of the telescopic rod 97, and both ends of the second spring 98 are fixedly connected to the upper and lower side brackets 94 respectively.

[0030] Through the above structure, the motor 99 provides a power source for the driving roller 93, and the two driving rollers 93 are fixedly connected by the telescopic rod 97, so that the bracket 94 can slide inside the second slide groove 96, and at the same time, the rebound force of the second spring 98 sleeved on the outside of the telescopic rod 97 makes the bracket 94 have elastic sliding characteristics, so that the driving roller 93 has a certain elastic adjustment ability, so that the driving roller 93 can be close to the inner wall of the flue pipe 1, thereby ensuring the driving ability inside the flue pipe 1.

[0031] In the utility model, when the smoke ash in the flue pipe 1 needs to be cleaned, the cleaning mechanism 9 is placed inside the flue pipe 1, and the motor 99 is started to drive the driving roller 93 to rotate. The driving roller 93 provides driving force for the structural box 91 to move and clean the inside of the flue pipe 1. When the structural box 91 moves inside the flue pipe 1, the outer end of the cleaning brush 92 on the outer surface thereof contacts the inner wall of the flue pipe 1 to sweep the smoke ash on the inner wall of the flue pipe 1. A telescopic rod 97 and a second spring 98 sleeved on the outer side of the telescopic rod are arranged between the other two groups of driving rollers 93. The elastic action of the second spring 98 causes the driving roller 91 to move and clean the inside of the flue pipe 1. 3 is close to the inner wall of the flue pipe 1 and has a certain elastic adjustment ability, which ensures the driving ability of the driving roller 93 inside the flue pipe 1 and also enables the driving roller 93 to have an adaptive adjustment driving ability in some small deformation flue pipes 1. The cleaning mechanism 9 is controlled to clean the dirt in the flue pipe 1 to the opening 2, and the ear handle 4 is pushed to slide inwardly of the first slide groove 5 to drive the blocking plate 3 to retract to the inside of the installation groove 7. At the same time, the opening 2 is opened, and the cleaned dirt is discharged from the opening 2. After cleaning, the opening 2 is closed, and the cleaning mechanism 9 is driven to move to the end of the flue pipe 1 and the cleaning mechanism 9 is taken out. The above is the working process and principle of the utility model. The utility model uses the cleaning mechanism 9 to drive the structural box 91 to move inside the flue pipe 1 using the driving roller 93, and drives the cleaning brush 92 on the surface of the structural box 91 to clean the inner wall of the flue pipe 1, thereby realizing the cleaning of the flue pipe 1. This cleaning method is practical and has a strong cleaning effect. At the same time, the cleaning mechanism 9 and the flue pipe 1 are separated. When the flue pipe needs to be cleaned, the cleaning mechanism 9 can be placed inside the flue pipe 1, which ensures the smoothness of smoke exhaust during daily use of the flue pipe 1 and greatly improves the practicality.
