[0005] In order to solve the above technical problems, the technical solution of the utility model is: a basement ventilation and purification structure, including a basement body, a support plate is fixedly connected to the top wall of the basement body, a placement cavity is formed between the support plate and the basement body, an air inlet pipe is fixedly connected to the basement body, an end of the support plate away from the air inlet pipe is fixedly connected to the air outlet pipe, the air inlet pipe and the air outlet pipe are both connected to the placement cavity, a mounting hole is opened on the lower surface of the support plate, a support frame located in the placement cavity is fixedly connected to the support plate, a purification box is slidably connected to the support frame, the lower end of the purification box is connected to the support frame by a snap-on structure, a cover plate is hinged on the mounting hole, and the cover plate and the support plate are connected by a positioning structure.

[0006] To implement the above technical solution, the purification box is passed through the installation hole from bottom to top and placed inside the support frame. As the purification box continues to be lifted, the purification box is positioned by the snap-fit ​​structure, and then the cover is flipped along the hinge, and the cover is positioned by the positioning structure. At this time, air enters the placement cavity from the air inlet pipe, and then passes through the purification box. After being purified by the purification box, it is discharged from the air outlet pipe and enters the inside of the basement body; as the purification box is used for a long time, the cover is opened from the support plate, the snap-fit ​​structure releases the purification box, and the purification box can be removed from the installation hole to facilitate replacement of the purification box; the cover can play a role in beautification and shielding dust falling from the purification box.

[0016] By implementing the above technical solution, the filter net can perform preliminary filtering on the wind.

[0017] As a preferred solution of the utility model, a placement groove is provided on the side wall of the air outlet pipe, and filter cotton is slidably connected in the placement groove.

[0018] By implementing the above technical solution, the filter cotton can further improve the filtering effect on wind. After the filter cotton has been used for a long time, the filter surface can be pulled out from the placement groove to replace the filter cotton.

[0019] As a preferred solution of the utility model, a fan is fixedly connected in the placement cavity, and the fan is located between the purification box and the air outlet pipe.

[0032] A mounting hole 5 with a square cross section is provided on the lower surface of the support plate 2, and the mounting hole 5 is connected to the placement cavity 21. A cover plate 51 is hinged on the inner wall of the mounting hole 5 through a pin, and the pin is located at one end of the mounting hole 5. The cover plate 51 is connected to the support plate 2 through a positioning structure 6.

[0033] The positioning structure 6 includes an L-shaped plate 61 and a rotating plate 62. One end of the L-shaped plate 61 is fixed to the side of the support plate 2 facing away from the placement cavity 21. One end of the rotating plate 62 is hinged to the cover plate 51, and the other end of the rotating plate 62 is used to contact the L-shaped plate 61. The rotating plate 62 is arranged in a rectangular parallelepiped. The cover plate 51 is supported by the rotating plate 62 and the L-shaped plate 61. There is friction between the rotating plate 62 and the cover plate 51.

[0034] A support frame 7 located in the placement cavity 21 is fixedly connected to the support plate 2, and the support frame 7 is opposite to the mounting hole 5. The support frame 7 is located on both sides of the mounting hole 5, and the support frame 7 has a mounting area 71 inside.
