[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0026] See also Figure 1 , 2 As shown in Figures , 3, 4, 5 and 6, the utility model provides a technical solution: a fan structure, comprising: a shell 1; a bottom plate 5 is embedded and clamped in the bottom of the shell 1, a fan 8 is installed above the bottom plate 5, a positioning pin 6 is fixed to the top of the bottom plate 5, and a positioning groove is provided on the side of the positioning pin 6; an interlocking structure is placed inside the shell 1, the interlocking structure comprises a positioning plate 10 fixed to the inside of the shell 1, the positioning plate 10 is an L-shaped structure, and a limit pin 11 interlocking with the positioning groove is slidably provided in the middle of the positioning plate 10; an air inlet pipe 15 is threadedly connected to one side of the shell 1, and a sealing ring is provided on one side of the air inlet pipe 15.

[0027] It should be noted that, when the utility model is maintaining the fan 8, the air inlet duct 15 is rotated outward to separate the air inlet duct 15 from the mounting plate 7, and then the connecting rod 12 is driven to move to one side through the interlocking structure, and the connecting rod 12 drives the limit latch 11 to move to one side. After the limit latch 11 is separated from the positioning pin 6, the base plate 5 is removed, so that the fan 8 can be taken out separately, which is convenient for maintenance and repair, and the disassembly is simple.

[0028] See also Figure 1 , 2 As shown in , 3 and 5 , air outlet nets 4 are embedded and installed on both sides of the shell 1 , a filter is installed inside the air outlet net 4 , a connecting pipe 2 is installed inside the shell 1 , an air outlet duct 3 is fixedly connected to the end of the connecting pipe 2 , and the air outlet duct 3 is connected to the air outlet net 4 .

[0029] It should be noted that the air outlet 3 of the utility model is a Y-shaped structure, and an ultraviolet sterilization lamp is installed inside the air outlet 3, which can output wind to both sides at the same time, and facilitate the uniform delivery of fresh air to the space on both sides, thereby effectively realizing ventilation and air circulation of the entire indoor space, and can also distribute air to a wider area, thereby improving the ventilation effect. A sealing gasket is provided at the bottom of the connecting pipe 2, which is provided with a base provided with the fan 8. When the air outlet of the fan 8 is connected to the connecting pipe 2, the connection between the two is sealed under the action of extrusion, and the air outlet net 4 is embedded and installed on the side of the shell 1 by magnetic attraction.

[0030] See also Figure 3 , 5As shown, a mounting plate 7 is fixedly connected to the top of the bottom plate 5 , and a fan 8 is fixedly connected to the mounting plate 7 . An embedding groove 9 is provided at the bottom of the housing 1 , and the bottom plate 5 is embedded and installed in the embedding groove 9 .

[0031] It should be noted that a rubber plate is installed on one side of the mounting plate 7 of the utility model corresponding to the air inlet pipe 15. When the air inlet pipe 15 and the mounting plate 7 are squeezed, the air inlet pipe 15 corresponds to the air inlet of the fan 8. The air inlet pipe 15 and the outer side of the mounting plate 7 are squeezed to achieve sealing, and a HEPA filter is arranged inside the air inlet pipe 15. When the fan 8 draws external air into the connecting pipe 2, the HEPA filter is filtered.
