DETAILED DESCRIPTION

[0022] For better understanding and implementation, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] In the description of the present invention, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside" and "outside" etc. indicating directions or positional relationships are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0024] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0025] Some embodiments of the present utility model disclose an air purifier, such as Figure 1-Figure 4 As shown, compared with the known air purifiers in the prior art, the space utilization rate is higher, the structure is more compact, and the volume is smaller.

[0026] The air purifier includes a housing 10. The housing 10 may be in the shape of a quadrangular prism as shown in the figure, and the four edges of the quadrangular prism housing 10 may be in arc transition. Of course, in some other embodiments, the housing 10 may be in the shape of a cylinder.

[0027] The air purifier further includes an air outlet assembly 20. The air outlet assembly 20 is disposed in the housing 10, and includes an air duct 21, a fan blade 22 disposed in the air duct 21, and a drive motor 23 disposed in the air duct 21 and transmission-connected to the fan blade 22. A mounting seat 24 is disposed in the air duct 21, and the drive motor 23 is disposed on the mounting seat 24.

[0028] According to the principle of the air purifier, the air duct 21, the fan blades 22 and the drive motor 23 are made into a combination, and then assembled into the shell 10. In this way, the structure inside the shell 10 will be more compact, which can improve the space utilization rate inside the shell 10, and thus can effectively control the volume of the air purifier as a whole; and, such a setting does not require the provision of an air guide cover structure, and the airflow can directly enter the air duct 21, which can reduce wind resistance to a certain extent, and can also reduce the noise caused by the airflow colliding with the air guide cover.

[0029] like Figure 2 and Figure 4As shown, optionally, the drive motor 23 is integrated at the bottom of the mounting seat 24, and the fan blade 22 is arranged on the lower side of the mounting seat 24. In this way, the fan blade 22 will be closer to the air inlet 13 on the outer side of the housing 10, which can increase the air intake efficiency of the air purifier.

[0030] like Figure 2-Figure 4 As shown, optionally, the fan blade 22 includes a fan middle portion 211 and a plurality of blades 212 arranged on the circumferential outer side of the fan middle portion 211, and the fan middle portion 211 is provided with an assembly cavity 213 at the top of the mounting seat 24, and the drive motor 23 is arranged in the assembly cavity 213. In this way, the structure can be made more compact, the space utilization rate in the housing 10 can be further improved, and the volume of the whole air purifier can be further effectively controlled.

[0031] Optionally, a clearance gap 25 is provided between the middle portion 211 of the fan and the opposite sides of the mounting seat 24. In this way, since the driving motor 23 drives the fan blade 22 to rotate, the clearance gap 25 is specially provided to avoid unnecessary friction between the middle portion 211 of the fan blade 22 and the mounting seat 24 to affect the operation of the fan blade 22.

[0032] like Figure 2 As shown, optionally, the air purifier further includes a partition 30. The partition 30 divides the cavity in the housing 10 into an upper cavity 11 and a lower cavity 12 arranged up and down, and the air outlet assembly 20 is arranged in the upper cavity 11. The partition 30 itself has a ventilation channel 31 arranged through, and in the height direction of the air purifier, the air outlet range of the ventilation channel 31 overlaps the air inlet range of the air duct 21. In this way, the airflow discharged from the ventilation channel 31 on the partition 30 all enters the air duct 21, and basically encounters no obstacles in the process, which can further reduce wind resistance and thus improve air outlet efficiency.

[0033] Optionally, the air purifier further includes a filter 40. The filter 40 is used to filter the airflow entering from the air inlet 13 on the housing 10. The filter 40 is arranged in the lower cavity 12. In this way, by arranging the filter 40, the airflow can be filtered first, and then flow from the lower cavity 12 to the upper cavity 11 through the ventilation channel 31, and then discharged to the air outlet 14 at the top of the housing 10 through the air duct 21, so as to achieve air purification.

[0034] Optionally, the filter element 40 may be a filter net or filter cotton, which has a simple structure, is easy to manufacture, and reduces the difficulty of manufacturing.

[0035] like Figure 3As shown, optionally, a plurality of spaced connection members 26 are provided between the circumferential outer side of the mounting seat 24 and the circumferential inner side of the air duct 21. In this way, each two adjacent connection members 26 are spaced apart, which means that a ventilation channel can be formed between each two adjacent connection members 26, that is, it can ensure that the airflow can be discharged from the air duct 21 to the air outlet 14 at the top of the housing 10, and at the same time, a stable support structure can be provided for the drive motor 23.

[0036] Optionally, at least one of the connecting members 26 is arranged to be inclined. In this way, the inclined connecting member 26 will form a wind guide structure, which is more conducive to the discharge of airflow and can also reduce wind resistance to a certain extent.

[0037] Optionally, a plurality of connecting members 26 are arranged at an angle to reduce wind resistance to the greatest extent.

[0038] like Figure 1 As shown, optionally, a plurality of air inlets 13 are provided at the bottom of the circumferential outer side of the housing 10, and an air outlet 14 is provided at the top of the housing 10. In this way, the air inlet range of the air purifier can be increased, thereby improving the efficiency of air purification.

[0039] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
