[0023] The following examples illustrate the present invention, but the present invention is not limited by these examples. Modifications to the specific implementation of the present invention or equivalent replacement of some technical features without departing from the spirit of the present invention should be included in the scope of the technical solution claimed for protection in the present invention.

[0024] Embodiment 1: Figures 1 to 3 As shown, this embodiment provides an air purification device, including:

[0025] The outer shell 1 is in a hollow cylindrical shape, and a base 2 is provided at the bottom of the outer shell 1;

[0026] The fan module 3 is detachably arranged at the end of the casing 1, and includes a guide member 31, a motor 32, a diagonal flow fan wheel 33 and an electronic control component 34. A radial opening 310 for air outlet is formed on the periphery of the guide member 31. The motor 32 and the electronic control component 34 are both arranged on the guide member 31. The electronic control component 34 is electrically connected to the motor 32. The diagonal flow fan wheel 33 is arranged on the rotating shaft of the motor 32. The diagonal flow fan wheel 33 extends into the casing 1, and the outer side of the guide member 31 is detachably connected to the end of the casing 1.

[0027] The air purification device provided in this embodiment has a simple structure and is convenient for cleaning the base.

[0028] Specifically, when the base 2 needs to be cleaned, the fan module 3 can be removed from the base 2. At this time, there is no powered module on the base 2, and the user can clean or soak the base 2 for collecting oil stains, thereby keeping the base 2 clean.

[0029] In addition, since the motor 32 and the electronic control component 34 are both integrated on the fan module 3, it is convenient to achieve electrical connection between the two, which is beneficial to improving the stability and reliability of product use.

[0030] In this embodiment, an anti-backflow groove 311 is provided at the transition point between the air outlet of the guide member 31 and the oblique flow wind wheel 33 to prevent high-speed airflow from flowing toward the inner hub, thereby avoiding the generation of vortexes, which is beneficial to reducing noise and increasing the air output of the air purification equipment.

[0031] The existing air purification equipment of the same type has a power of 24W, an air volume of 250.2m3 / h, and a maximum wind speed of 5.5m / s at the center of the inlet;

[0032] The air purification device provided in this embodiment has a power of 24W, an air volume of 361.5m3 / h, and a maximum wind speed of 6.5m / s at the center of the air inlet.

[0033] It can be seen that the air purification device provided in this embodiment has a greatly improved air output and maximum wind speed at the center of the air inlet compared to existing products.

[0034] In this embodiment, a honeycomb-shaped protective net 4 is provided in front of the diagonal flow impeller 33 and inside the outer shell 1, thereby rectifying the air into a uniform form. The air in a uniform form enters the interior of the air purification device, thereby avoiding turbulence and noise.

[0035] Furthermore, the cross-sectional area of ​​the protective net 4 is larger than the cross-sectional area of ​​the air inlet of the diagonal flow wind wheel 33, thereby reducing the structural wind resistance and increasing the air intake volume.

[0036] Furthermore, an oil collecting filter module 5 is provided at the air inlet end of the housing 1, which includes an oil collecting cover 51 and a metal filter screen 52 assembled together, and a magnetic attraction structure 6 is provided between the oil collecting filter module 5 and the housing 1, so that the oil collecting cover 51 and the metal filter screen 52 are disassembled and assembled as a whole, thereby making it more convenient to assemble the product. In addition, the magnetic attraction structure 6 facilitates the connection and fixation between the oil collecting filter module 5 and the housing 1.

[0037] In this embodiment, an adsorption filter module 7 is provided between the oil collecting filter module 5 and the protective net 4. The adsorption filter module 7 may adopt an activated carbon filter adsorption module, thereby improving the filtering and purification effects of the air purification equipment.

[0038] Furthermore, an annular stepped oil guide groove 510 is provided in the oil collecting hood 51, an oil outlet 511 is provided at the bottom of the oil guide groove 510, and an oil cup 8 is provided below the oil outlet 511 and in the base 2. The oil guide groove 510 not only supports the metal filter 52, but also allows the oil and water condensed at the air inlet end to flow into the bottom oil cup 8 through the oil guide groove 510. Compared with the existing oil and water flowing outside the air purification equipment, the air purification equipment can be kept cleaner.

[0039] In this embodiment, an oil guide structure 21 is provided at the connection between the top of the base 2 and the outer shell 1. The oil guide structure 21 is funnel-shaped. The flow characteristics of the liquid are utilized to make the oil and water gather at the center point to form water droplets, which then drip into the oil cup through the oil guide structure 21, thereby reducing the contact of oil stains with the surfaces of other structural parts, minimizing the pollution of the fuselage, and facilitating cleaning.

[0040] Furthermore, a platform 22 is provided in the base 2 for supporting the oil cup 8 , and the platform 22 has a simple structure, thereby enabling the oil cup 8 to be placed more stably.

[0041] Furthermore, gripping portions 81 are respectively provided on both sides of the oil cup 8 , thereby facilitating the user to take and place the oil cup 8 .

[0042] The above are only some embodiments of the present invention. For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
