[0034] Reference Figure 4 , Figure 5 The cleaning component includes a fixing frame 14. The function of the fixing frame 14 is to provide support and fixation for the cleaning component to ensure its stability and reliability inside the ventilation pipe 1. The fixing frame 14 is fixedly connected to the inside of the ventilation pipe 1. The bottom end of the ventilation pipe 1 is fixedly connected to a collecting box 15. The collecting box 15 is used to collect and store debris and dirt during the cleaning process to facilitate subsequent processing and cleaning. A motor 16 is fixedly connected to the right side of the fixing frame 14. The motor 16 serves as a driving force source for the cleaning component and is responsible for pushing the moving parts during the cleaning process to achieve the cleaning operation inside the ventilation pipe 1. The upper and lower sides of the driving end of the motor 16 are fixedly connected to connecting plates 17.

The brush end of the brush head 20 contacts the inner wall of the ventilation pipe 1. The contact between the brush end and the inner wall of the ventilation pipe 1 can thoroughly remove dirt and debris in the pipe, keep the ventilation system clean and unobstructed, and ensure the improvement of air quality and the normal operation of the system. The limit block 10 slides inside the ventilation pipe 1. The sliding design of the limit block 10 enables the ejection assembly to move freely inside the ventilation pipe 1, and ensures the accurate positioning of the ejection block 9 during the ejection operation, thereby improving the accuracy and efficiency of the operation. The material of the filter plate 7 is activated carbon filter material. Using activated carbon filter material as the material of the filter plate 7 can effectively remove odors and harmful gases in the air, improve the purification effect of the ventilation system, and ensure the freshness and health of the indoor air.

A filter screen 12 is fixed on the left side of the first fan 13 to filter relatively large impurities and garbage, and the filter plate 7 on the right side of the second fan 23 is used to filter smaller impurities. By pulling the pulling block 2, the pulling block 2 can be taken out from the inside of the filter plate 7, and the filter plate 7 can be taken down in time for cleaning. There is a rotating rod 4 on the top of the pulling block 2. When the pulling block 2 is pulled, the rotating rod 4 will be driven to rotate, and the other end of the rotating rod 4 is rotated with a sliding plate 5. The other end of the sliding plate 5 has a spring 6 connected to the inside of the ventilation pipe 1. Under normal conditions, the spring 6 can provide a certain resilience to the pulling block 2, so that the pulling block 2 can fix the filter plate 7 on the right side of the ventilation pipe 1. There is a slider 3 at the bottom of the pulling block 2, which can To limit the movement range of the pulling block 2, there is an elastic sliding rod 8 at the right end of the ventilation pipe 1, and the ejection block 9 slides on the outside of the sliding rod 8. The limit block 10 on the left side of the ejection block 9 has a spring 2 11 connected to the inside of the ventilation pipe 1, so that the filter plate 7 can be more easily removed. There is a fixing frame 14 inside the ventilation pipe 1, and a collecting box 15 is arranged on the fixing frame 14. The driving end of the collecting box 15 has a connecting plate 17, and the other end of the connecting plate 17 has a buffer plate 18. A plurality of telescopic rods 19 are connected in the middle of the buffer plate 18 and the brush head 20, so the outside of the telescopic rod 19 is provided with a spring 3 21, which can extend the service life of the brush head 20. A scraper 22 is arranged at the rightmost end of the driving end of the motor 16, which can scrape the impurities and dust on the inner wall of the ventilation pipe 1 to the vicinity of the brush head 20, and then collect them into the collecting box 15 at the bottom of the ventilation pipe 1 through the brush head 20.
