The box body 1 comprises a fan box 11 and an air outlet 12. The inner bellows 2 is installed inside the box body 1. The inner bellows 2 is located at the bottom of the box body 1. The air outlet 12 is located at the top of the box body 1. The fan box 11 is installed with a first fan 21. The inner bellows 2 comprises an air guide box 22. The first fan 21 is connected to the air guide box 22. The air guide box 22 comprises a closed area 222 and an air guide area 223. The closed area 2 The upper end face and the lower end face of 22 are both in a closed state, and the closed area 222 is provided with an air inlet 221, and the air inlet 221 is connected to the first fan 21, and the closed area 222 is connected to the first fan 21 and the wind guide area 223. The closed area 222 is funnel-shaped, and the cross-sectional area of ​​the closed area 222 gradually expands from the air inlet 221 toward the wind guide area 223. The hot air from the first fan 21 enters from the air inlet 221 and can only flow to the wind guide area 223 through the closed area 222, so that the incoming hot air can be diffused.

[0028] The upper end of the air guide box 22 is provided with an opening, that is, the upper end surface of the air guide area 223 is provided with an opening, and the air guide box 22 is provided with a plurality of first air guide plates 224, which are arranged and installed in the air guide area 223, and the first air guide plates 224 extend along the air outlet direction of the first fan 21, and the hot air in the closed area 222 enters the air guide area 223 and contacts the first air guide plates 224, and the first air guide plates 224 are wavy, and the plurality of first air guide plates 224 are arranged along the length direction of the inner wind box 2, and an air guide channel 225 is formed between two adjacent first air guide plates 224, and the width of the air guide channel 225 is from the middle of the inner wind box 2 to the The two sides gradually increase, and the first air guide plate 224 in the inner bellows 2 can divide the hot air delivered by the first fan 21. The hot air flows through the air guide channel 225 between the wavy first air guide plates 224, which can slow down the flow rate of the hot air. The smaller the distance between the two first air guide plates 224, the slower the wind speed of the hot air flowing through, which increases the wind resistance of the hot air flowing through the middle part of the inner bellows 2, and the wind resistance flowing to the two sides of the inner bellows 2 is smaller, which slows down the wind speed in the middle part of the inner bellows 2 and speeds up the wind speed on both sides, thereby increasing the temperature on both sides of the inner bellows 2, balancing the temperature between the middle part and the two sides of the inner bellows 2, and making the temperature of the hot air flowing upward from the inner bellows 2 more balanced.

The air induction holes 227 connect the air guide channel 225 and the annular wind groove 14. The air induction holes 227 can guide part of the hot air in the air guide channel 225 into the annular wind groove 14, thereby increasing the temperature of the end of the air guide channel 225 away from the first fan 21, and making the temperature of the inner bellows 2 more uniform.

[0032] More preferably, the inner bellows 2 is provided with a plurality of air induction plates 228, each air induction hole 227 is provided with an air induction plate 228, the air induction plates 228 are located on the outer wall of the inner bellows 2, the air induction plates 228 are located on the side of the air induction hole 227 close to the second fan 15, the air induction plates 228 are tilted, and the end of the air induction plates 228 away from the inner bellows 2 is tilted toward the direction away from the second fan 15, the air induction plates 228 can block the airflow from the second fan 15 toward the air induction holes 227, and prevent the airflow in the annular wind groove 14 from affecting the airflow in the air guide channel 225, and the airflow flowing in the annular wind groove 14 can induce the airflow in the air induction holes 227 so that the airflow in the air guide channel 225 can be better guided to the end away from the first fan 21.

[0033] The filter device 3 is located above the inner bellows 2. The filter device 3 includes a filter screen 31 and two cleaning brush mechanisms 32.

The brush plate 322 is slidably installed on the support frame 33. When the mesh roll 311 gradually increases due to winding, the pressure roller 323 is supported by the mesh roll 311 and can gradually compress the spring 325. The position of the brush plate 322 can move with the movement of the pressure roller 323, and can maintain the distance between the brush plate 322 and the mesh roll 311, so as to prevent the bristles 3221 from contacting the mesh roll 311 too much, resulting in poor effect of brushing off dust. Two cleaning mechanisms 32 are provided to clean back and forth between the two mesh rolls 311. When the mesh roll 311 at one end is fully rolled up, the two rotating shafts 321 rotate in the opposite direction to unwind the cleaned mesh roll 311 in the opposite direction, and the cleaned filter screen 31 can be reused.
