[0002] An air purifier is a device used to filter air. Existing air purifiers include a housing, a filter, and a fan. The housing has an air guide cavity, an air inlet, and an air outlet. The fan and filter are housed within the air guide cavity, with the fan positioned to one side of the filter to drive air from the air inlet to the air outlet. Because the air guide cavity lacks defined air ducts, when the fan drives air from the air inlet to the air outlet, some air is filtered before being discharged, while some is discharged unfiltered, resulting in poor air purification. Utility Model Content

[0003] The purpose of this invention is to provide a vertical air purifier to solve the problem that existing air purifiers do not have air ducts in their air guide cavity, resulting in some air flowing into the air guide cavity being discharged directly without filtration, leading to poor air purification effect.

[0004] This utility model is achieved through the following technical solution:

[0005] A vertical air purifier includes a shell, a top cover, a bottom cover, a filter element, and a fan. The shell has an outer cylinder and an inner cylinder. The inner cylinder is housed within the outer cylinder and extends from the top of the outer cylinder to its middle.

[0024] Example: Figure 1-5 As shown, the vertical air purifier includes a shell 1, a top cover 2, a bottom cover 3, a filter element 4, and a fan 5. The shell 1 has an outer cylinder portion 101 and an inner cylinder portion 102. The inner cylinder portion 102 is housed within the outer cylinder portion 101 and extends from the top of the outer cylinder portion 101 to the middle of the outer cylinder portion 101. The top cover 2 covers the upper end of the inner cylinder portion 102 and together with the inner cylinder portion 102 forms an air outlet cavity 103 for housing the fan 5. The air outlet cavity 103 has several air outlet holes 20 formed on the top cover 2. 1. It is connected to the outside. The bottom cover 3 is installed on the lower end of the outer cylinder 101 and together with the outer cylinder 101 to form an assembly cavity 104. The filter element 4 is housed in the assembly cavity 104 and divides the assembly cavity 104 into an independent air inlet space 105 and a filter space 106. The air inlet space 105 is connected to the outside through a number of air inlet holes 107 opened on the outer cylinder 101. The filter space 106 is connected to the air outlet cavity 103 through a connecting hole 108 opened on the inner cylinder 102.

[0025] When the fan 5 starts to draw air, the gas enters the air intake space 105 through the air inlet 107. Then, the gas passes through the filter element 4 and enters the filter space 106. Next, the gas enters the air outlet chamber 103 through the connecting hole 108. Finally, the gas is discharged through the air outlet 201, completing the air filtration.

[0026] In summary, this embodiment provides a vertical air purifier to solve the problem that existing air purifiers do not have a divided air duct in the air guide cavity, resulting in some air flowing into the air guide cavity being discharged directly without filtration, leading to poor air purification effect. The main solution is to configure the vertical air purifier as a cylindrical shell 1, a top cover 2, a bottom cover 3, a filter element 4, and a fan 5. The cylindrical shell 1 is configured with an outer cylindrical part 101 and an inner cylindrical part 102. The outer cylindrical part 101, the filter element 4, and the bottom cover 3 together form an air inlet space 105 and a filtration space 106. The inner cylindrical part 102 and the top cover 2 together form an air outlet cavity 103 that communicates with the filtration space 106 for gas exhaust. When the fan 5 starts to draw air, the unfiltered air enters the air inlet space 105, is filtered by the filter element 4, and then all enters the filtration space 106 before being discharged. The filtration effect is good, and the cylindrical design has a large air intake ratio and high filtration efficiency.

[0027] In this embodiment of the invention, the outer shell 1, the upper cover 2, and the bottom cover 3 constitute the outer shell. The inner cylinder 102 has a stop portion 109 that abuts against the filter element 4 and a positioning portion 110 that extends at least partially into the filtration space 106.

By configuring the inner cylinder 102 to have a stop portion 109 that abuts against the filter element 4, the filter element 4 and the inner cylinder 102 are tightly fitted, preventing air in the air inlet space 105 from entering the air outlet cavity 103 through the gap between the filter element 4 and the inner cylinder 102, thus affecting the filtration effect. Furthermore, by configuring the inner cylinder 102 to have a positioning portion 110 that extends into the filtration space 106, the positioning and installation of the filter element 4 is facilitated.

[0028] In this embodiment of the utility model, the lower end of the filter element 4 abuts against the bottom cover 3.
