Detailed Description
The utility model will be further described with reference to the drawings and specific examples.
As shown in fig. 1 and 2, a photocatalytic air purification device includes a base 1, a housing 2, and a top chassis 3, the housing 2 being disposed between the base 1 and the top chassis 3.
The base 1 is circular, and the top is inwards recessed to form a connecting part 4. The shell 2 is circular, has the same diameter as the base 1, and is sleeved outside the connecting part 4 at the bottom, so that an air inlet channel is formed between the top of the base 1 and the bottom of the shell 2.
As shown in fig. 3 to 5, the outer wall of the top of the connecting portion 4 is fixedly connected with the inner wall of the bottom of the housing 2 through a first connecting rod 5 extending to the outside of the base 1.
