The ventilation holes 20 are symmetrical with the output end of the driving fan 2 as the center, the driving fan 2 drives the fan blade 3 to rotate, and the fan blade 3 blows the wind sucked from the rear out from the heating mesh plate 5 in the front.

[0022] A sliding ring 6 is provided at the rear of the outer shell 1, and sliding blocks 7 are fixedly connected to the upper and lower ends of the sliding ring 6. The inner wall of the sliding ring 6 is respectively fixedly connected with a first filter 8 and a second filter 9. The first filter 8 is arranged on the outside, and the second filter 9 is arranged on the inside. The first filter 8 is used to filter large particles of dust, and the second filter 9 is used to filter smaller particles of dust. The first filter 8 and the second filter 9 filter out most of the dust and impurities brought by the fan blades 3 when sucking wind. By setting the first filter 8 and the second filter 9 to filter the inhaled dust, it helps to prevent the components of the high-temperature fan from being worn by the inhaled dust particles, thereby extending the service life of the driving fan 2.

[0023] A connecting mechanism 10 is provided at the sliding connection between the sliding block 7 and the outer shell 1. The connecting mechanism 10 includes a spring 11, a clamping block 12 and a push rod 13. A groove is provided inside the sliding block 7. A spring 11 is provided inside the groove. One end of the spring 11 is fixedly connected to the groove. The other end of the spring 11 is fixedly connected to the clamping block 12. A through hole is provided at the connection of the outer shell 1. A fixed block 14 is fixedly connected inside the through hole. The push rod 13 enters the through hole and is slidably connected to the fixed block 14. The upper and lower ends of the push rod 13 are fixedly connected to the limiting block 15. Pressing the push rod 13 pushes the clamping block 12 downward to make the sliding ring 6 detachable.

[0024] When the first filter 8 and the second filter 9 need to be cleaned, press the push rod 13, the push rod 13 pushes the clamping block 12 downward, the spring 11 is compressed, and then the sliding ring 6 is taken out. When the cleaning is completed, the sliding block 7 and the outer shell 1 are slid and installed. When the clamping block 12 reaches the through hole opened in the outer shell 1, the clamping block 12 is pushed upward, and then the clamping block 12 is clamped in the through hole to fix the sliding ring 6.

If the protective plates 16 at the upper and lower ends are to be replaced, the bolts 19 need to be removed first. By providing the protective plates 16, the inner wall of the outer shell 1 can be effectively protected to prevent unfiltered dust from wearing the inner wall, thereby extending the service life of the high-temperature fan. At the same time, the modular design of the protective plates 16 allows the severely worn protective plates 16 to be replaced first, without the need to replace the entire protective plate 16, which can reduce the cost of maintenance and replacement and improve the use efficiency and economy of the protective plates 16.

[0026] Working principle: First, start the driving fan 2 to drive the fan blades 3 to rotate. The fan blades 3 blow the wind sucked from the rear out through the heating mesh plate 5 in front. The first filter 8 and the second filter 9 filter out most of the dust and impurities brought by the fan blades 3 when sucking wind. The unfiltered dust particles wear the protective plate 16.

[0027] When the first filter screen 8 and the second filter screen 9 need to be cleaned, the push rod 13 is pressed down, and the push rod 13 pushes the clamping block 12 downward, the spring 11 is compressed, and then the sliding ring 6 is taken out. When the cleaning is completed, the sliding block 7 and the outer shell 1 are slid and installed. When the clamping block 12 reaches the through hole opened in the outer shell 1, the clamping block 12 is pushed upward, and then the clamping block 12 is clamped in the through hole to fix the sliding ring 6.
