[0030] The following refers to Figures 1 to 7 to describe the air purifier according to the embodiments of the present invention.

[0031] The air purifier according to the embodiments of the present invention includes a front housing 100, a filter layer, and a rear housing 300. The front housing 100 includes a front panel 110, and the front panel 110 is covered with air inlets 111; the filter layer is located inside the front housing 100, behind the air inlets 111; the front housing 100 is connected to the rear housing 300, a centrifugal fan 400 is provided inside the rear housing 300, and an air outlet 310 is provided at the top of the rear housing 300.

[0032] For example Figure 1 、 Figure 3 and Figure 6 As shown, the front housing 100 includes a front panel 110, and the front panel 110 is covered with air inlets 111, enabling the front panel 110 to intake air over a large area and increasing the air intake area. The filter layer is located inside the front housing 100, behind the air inlets 111, such that after the air enters from the air inlets 111, it directly enters the filter layer for filtration.

[0033] The front housing 100 is connected to the rear housing 300. A centrifugal fan 400 is disposed inside the rear housing 300. The centrifugal fan 400 drives the air to enter from the air inlets 111, pass through the filter layer for filtration, and then flow out from the top air outlet 310 of the rear housing 300.

[0034] The travel distance of the air between the air inlets 111 and the air outlet 310 is short, reducing the structural resistance. Moreover, the front panel 110 is covered with air inlets 111, enabling large-area air intake and accelerating the air purification efficiency. At the same time, due to the large-area air intake, the air flow rate can be reduced. The reduced air flow rate allows the air to have more contact time with the filter layer, ensuring the filtration effect and making the purification efficiency of the air purifier higher.

[0035] In some specific embodiments of the present utility model, the air inlets 111 are strip-shaped air inlets.

[0036] For example Figure 1 As shown, the air inlets 111 are strip-shaped air inlets. The air inlets 111 are disposed on the front panel 110, and the structure is a strip-shaped opening structure with a flat-wave structure. The strip-shaped opening structures are evenly distributed on the front panel 110, which can ensure the uniform distribution of the air flow entering the filter layer. The uniform distribution setting can ensure the full-effect use of the filter element, and can ensure that the air intake cross-section has a sufficiently large air intake area, optimizing the structural resistance of the air intake channel.

[0037] In some specific embodiments of the present utility model, there is also an air duct wall 320. The air duct wall 320 is disposed inside the rear housing 300, faces the centrifugal fan 400, and semi-surrounds the centrifugal fan 400 from the bottom of the centrifugal fan 400.

[0038] For example Figure 5 As shown, the air purifier further includes an air duct wall 320. The air duct wall 320 is disposed inside the rear housing 300, faces the centrifugal fan 400, and semi-surrounds the centrifugal fan 400 from the bottom of the centrifugal fan 400, such that after the air is sucked by the centrifugal fan 400 from the filter layer, it can be directly blown towards the air outlet 310, accelerating the purification efficiency.

[0039] In some specific embodiments of the present utility model, the air duct wall 320 is in the shape of an Archimedean spiral.

[0040] For example Figure 5 As shown, the air duct wall 320 is in the shape of an Archimedean spiral, which can further increase the air intake volume.

[0041] In some specific embodiments of the present utility model, the air outlet 310 is located above the centrifugal fan 400 and the air duct wall 320.

[0042] For example Figure 5 As shown, the air outlet 310 is located above the centrifugal fan 400 and the air duct wall 320, shortening the travel distance of air from the centrifugal fan 400 to the air outlet 310 and accelerating the purification efficiency.

[0043] In some specific embodiments of the present utility model, a handle 120 is provided at the top of the front housing 100.

[0044] For example Figure 3 and Figure 4 As shown, a handle 120 is provided at the top of the front housing 100, which facilitates people to lift the air purifier and move the air purifier.

[0045] In some specific embodiments of the present utility model, a dust sensor air inlet 130 and / or an odor sensor air inlet 140 are provided at the front panel 110.

[0046] For example Figure 1 As shown, a dust sensor air inlet 130 and an odor sensor air inlet 140 are provided at the front panel 110, and a dust sensor and an odor sensor are arranged inside the housing, so that the air purifier can not only purify the air, but also detect whether the dust concentration and odor in the air are normal.

[0047] Furthermore, a display panel 150 is further included, and the display panel 150 can display the air flow rate, dust concentration and odor.

[0048] In some specific embodiments of the present utility model, a base 500 is further included, the base 500 is arranged at the bottoms of the front housing 100 and the rear housing 300, and a rubber soft plug support 510 is arranged at the bottom of the base 500.

[0049] For example Figure 1 and Figure 7 As shown, a base 500 is arranged at the bottom of the air purifier, the base 500 is arranged at the bottoms of the front housing 100 and the rear housing 300 and is connected to the front housing 100 and the rear housing 300. Furthermore, a rubber soft plug support 510 is further arranged at the bottom of the base 500, so that the air purifier can be placed more stably on the ground or on the table.

[0050] In some specific embodiments of the present utility model, the filter layer includes a primary filter cotton 210, an activated carbon filter layer 220, a formaldehyde removal filter layer 230, and an ultraviolet purification section 240.

[0051] For example Figure 3 As shown, the filter layer includes a primary filter cotton 210, an activated carbon filter layer 220, a formaldehyde removal filter layer 230, and an ultraviolet purification section 240. The primary filter cotton 210, the activated carbon filter layer 220, and the formaldehyde removal filter layer 230 can purify particulate pollutants, gaseous pollutants, and formaldehyde pollutants from decoration in the room. The ultraviolet purification section 240 is arranged behind the primary filter cotton 210, the activated carbon filter layer 220, and the formaldehyde removal filter layer 230 and before the centrifugal fan 400. The ultraviolet purification section 240 can generate ultraviolet rays with a wavelength of 253.7 nm, which can kill bacteria and viruses in the air flowing through the ultraviolet purification section 240.

[0052] In some specific embodiments of the present utility model, a remote control placement groove 330 is recessed inward on the surface of the rear housing 300 for placing the remote control.

[0053] For example Figure 4 As shown, a remote control placement groove 330 is recessed inward on the surface of the rear housing 300 for placing the remote control, making the air purifier more convenient to use.
