[0018] The following is a further non-limiting detailed description of the technical solution of the utility model in conjunction with the preferred embodiments and the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-3The utility model provides a technical solution: a boiler flue with an internal ash-cleaning function, comprising a flue body 1, a filter plate 2 is fixedly connected at the outlet of the flue body 1, and the inner wall of the filter plate 2 is movably connected with a support shaft 3, one end of the support shaft 3 is fixedly connected with a fan blade 4, and the other end of the support shaft 3 is fixedly connected with a cleaning brush 5. A fixing block 6 is fixedly connected to the top of one end of the flue body 1, and a waste discharge port 7 is opened at the bottom of one end of the flue body 1. A collecting box 8 is arranged at the bottom of the waste discharge port 7, and a fixing shaft 9 is fixedly connected to the inner wall of the collecting box 8, and a volute spring 10 is fixedly connected to the outer wall of the fixing shaft 9, and a positioning clamp 11 is fixedly connected to the outer wall of the volute spring 10, which realizes the function of facilitating filtering, prevents pollution caused by smoke emission, and is conducive to automatic ash cleaning during filtering, solves the problem of easy blockage, and at the same time facilitates the collection of cleaned dust, improves the convenience of operation, meets people's work needs, and is worthy of popularization and use.

[0020] Furthermore, the cleaning brush 5 forms a linkage structure with the fan blades 4 through the support shaft 3, and one end of the cleaning brush 5 is fitted with the inner side of the filter plate 2 through the brush, which facilitates automatic cleaning during smoke emission.

[0021] Furthermore, the fixing block 6 has a concave-shaped structure when viewed from the front, and a semicircular structure when viewed from the side, which facilitates the fixing block 6 to limit the positioning clip 11.

[0022] Furthermore, the size of the collection box 8 is larger than the size of the waste outlet 7, which facilitates the collection of the cleaned dust.

[0023] Furthermore, the fixed shaft 9 and the positioning clip 11 are through-connected, and there are two positioning clips 11 symmetrically distributed, which facilitates the support of the positioning clips 11 .

[0024] Furthermore, the positioning clip 11 forms a rotating structure with the fixed shaft 9 through the spiral spring 10, and the positioning clip 11 is arranged in an arc shape, which facilitates the clamping work after driving the positioning clip 11 to reset and rotate.

[0025] When in use, first, the positioning clamp 11 is toggled to rotate, so that the positioning clamp 11 drives the scroll spring 10 to deform, and then the collection box 8 is installed to the bottom of the waste outlet 7, and the positioning clamp 11 is loosened, so that the scroll spring 10 drives the positioning clamp 11 to reset and rotate and then clamp it with the fixing block 6, thereby completing the installation of the collection box 8. At this time, the smoke passes through the filter plate 2 during discharge to filter the internal dust, and drives the fan blades 4 to rotate through the flow power, so that the fan blades 4 drive the cleaning brush 5 to rotate through the support shaft 3, and then the cleaning brush 5 automatically cleans the filter holes of the filter plate 2, preventing the filter plate 2 from being blocked and affecting the emission efficiency of the smoke. The cleaned dust falls into the interior of the collection box 8 through the waste outlet 7 for collection, thereby improving the convenience of the overall operation and solving the cumbersome operation caused by manual cleaning and manual collection.
