[0002] The problem of air pollution has become increasingly prominent in today's society, seriously endangering people's health. In order to cope with the worsening air pollution problem, various air treatment devices are widely used in homes, office buildings, bedrooms, living rooms, hospitals, hotels and other places. Among them, the fresh air device is a relatively widely used and practical air treatment device.

[0003] The fresh air fan is an effective air purification device that can circulate indoor air. The window-type fresh air fan is an air purification device installed on the window. It can provide fresh air to the room and exhaust polluted air, thereby improving the indoor air quality. On the one hand, it discharges the polluted indoor air (containing a large number of pathogens, high carbon dioxide content and low oxygen content) to the outside. On the other hand, the fresh outdoor air (low pathogen content, low carbon dioxide content and high oxygen content) is sterilized, disinfected, filtered and other measures before being input into the room, so that the room is filled with fresh and clean air at all times. The fresh air fan uses fresh air convection technology to achieve indoor air convection through autonomous air supply and air intake, thereby maximizing indoor air replacement. The fresh air fan has a built-in multi-functional purification system to ensure that the air entering the room is clean and healthy.

[0004] Most of the window-type fresh air fans on the market are equipped with filters, and the filters need to be cleaned after being used for a long time.

[0030] The cleaning structure includes a fixing bracket 16, a cleaning brush 17 and a guiding block 19. The fixing bracket 16 and the guiding block 19 are both fixedly connected to the inner wall of the mounting frame 3, and the cleaning brush 17 is fixedly connected to the end of the fixing bracket 16.

[0031] Among them, the cleaning brush 17 is a nylon cleaning brush.

[0032] It should be noted that a nylon cleaning brush is a tool commonly used for cleaning and removing stains, and it is made of nylon fibers.

[0033] And the nylon brush has the following characteristics:

[0034] Durability: Nylon fibers have strong abrasion resistance and durability, so nylon cleaning brushes can be used for a long time without being easily damaged.

[0035] Softness: Nylon brushes are relatively soft, so they cause less damage to the surface of the object being cleaned during the cleaning process and are suitable for occasions with high surface treatment requirements.

[0036] Antistatic: Nylon materials have good antistatic properties and can effectively remove and prevent the accumulation of static electricity on the surface of objects.

[0037] Diversity: According to needs, nylon cleaning brushes can be made into different shapes and specifications to adapt to different cleaning occasions and requirements.

[0038] It can be understood that by pulling the handle 7 to drive the displacement of the movable rod 9, and the movable rod 9 is limited by the telescopic spring 8 and the limiting plate 10. After the movable rod 9 disengages from the contact with the filter plate 4, the filter plate 4 and the filter net 5 can be detached from the installation frame 3 through the pull ring 14. When the filter plate 4 and the filter net 5 slide down and are detached from the installation frame 3, the fixed frame 16 and the cleaning brush 17 can be used to scrape and clean the filter net 5, and the impurities in the filter net 5 will be discharged through the slag discharge hole 18 and the discharge hole 15, and the guide block 19 can guide the impurities out of the discharge hole 15.

[0039] In this embodiment, a filter plate 4 abuts against the inside of the installation frame 3, a filter net 5 is arranged inside the filter plate 4, and a pull ring 14 is fixedly connected to the lower end of the filter plate 4.

[0040] In this embodiment, through holes are formed in the filter plate 4, and the movable rod 9 passes through the filter plate 4 through the through holes.

[0041] In this embodiment, limiting holes are formed in both the limiting plate 10 and the installation frame 3, and the movable rod 9 passes through the limiting plate 10 and the installation frame 3 through the limiting holes.

[0042] In this embodiment, a clamping groove is formed in the installation frame 3, and the end of the movable rod 9 is inserted into the installation frame 3 through the clamping groove.

[0043] In this embodiment, a slag discharge hole 18 is formed in the fixed frame 16, and a discharge hole 15 is formed in the lower end of the installation frame 3.

[0044] Among them, the impurities cleaned out from the filter net 5 are all discharged through the slag discharge hole 18 and the discharge hole 15.

[0045] In this embodiment, a ventilation and waterproof structure is provided on the installation frame 3. The ventilation and waterproof structure includes a fixing plate 12 and a waterproof and breathable membrane 13.

[0046] Among them, the number of ventilation holes 11 is several, and the ventilation holes 11 are rectangular in shape.

[0047] The working principle of the above embodiment is as follows:

[0048] First, connect the installation frame 3 and the fresh air fan body 1 through the connection frame 2.

[0049] Secondly, pull the handle 7 to drive the displacement of the movable rod 9. The movable rod 9 is limited by the telescopic spring 8 and the limiting plate 10. After the movable rod 9 is separated from the contact with the filter plate 4, the filter plate 4 and the filter net 5 can be detached from the installation frame 3 through the pull ring 14. When the filter plate 4 and the filter net 5 are detached and slide down from the installation frame 3, the fixing frame 16 and the cleaning brush 17 can be used to scrape and clean the filter net 5, and the impurities in the filter net 5 will be discharged through the slag discharge hole 18 and the discharge hole 15, and the guide block 19 can guide the impurities out of the discharge hole 15.
