Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present invention. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

The embodiment of the application provides an air purifier's wind channel structure.

As shown in fig. 1-2, the air cleaner duct 300 of the present embodiment includes a housing 100 and support legs 200, the housing 100 is provided with an air duct 300 extending in an up-and-down direction, an air inlet 310 opened downward is formed at a lower portion of the air duct 300, and an air outlet 320 opened upward is formed at an upper portion of the air duct 300.

The bottom of casing 100 is located to a plurality of supporting leg 200, and the one end of supporting leg 200 is connected with the bottom of casing 100, and the connected mode can be fixed connection or can dismantle the connection, and the mode that can dismantle the connection adopts threaded connection. The support legs 200 may keep the housing 100 away from a plane on which the air purifier is placed, which is generally a flat floor even though the air inlet 310 is away from the floor. The air duct 300 is arranged in the vertical direction, that is, the air inlet 310 can be provided with air in the direction of 360 degrees. Thereby improve the efficiency of taking a breath, also less some restrictions to air purifier's locating place, let the consumer can be more free put their air purifier. And in order to make the efficiency of air intake 310 can promote, this embodiment adopts 4 supporting legs 200 to set up at interval each other, can all carry out the circulation of air between each supporting leg 200, air intake 310 still can follow 360 degrees direction air intakes, and supporting leg 200 props up casing 100, make air intake 310 and the plane of placing between be formed with first interval, on the basis that the intake of guaranteeing air intake 310 is not influenced, whole air purifier's whole volume is reduced as far as possible, the scope control of this first interval is 9-12 cm. In fig. 3, it is shown the influence on the intake air volume of the intake vent 310 when the first distance is changed by using the structure of the air duct 300 of this embodiment. Preferably, in one embodiment, the first spacing is chosen to be 9.5 cm. The distance takes account of the air inlet amount of the air inlet 310 and the whole volume, so that the structure volume of the air purifier is small, and the requirement of air exchange efficiency is met.

In one embodiment, the cross-sectional shape of the support leg 200 is circular, and the entire support leg 200 is cylindrical. The supporting legs do not occupy too much space, the influence of the cylindrical supporting legs 200 on the air inlet efficiency is small, the movement of air flow is stable, and further, the sectional areas of the supporting legs 200 are gradually reduced from top to bottom.

In one embodiment, the support leg is provided with a stud (not shown) at one end and the housing 100 is provided with a threaded hole (not shown) adapted to the stud. Make the supporting leg dismantle, can make air purifier's volume further reduce when not using, convenient transportation and storage.

In one embodiment, an axial fan 400 is disposed within the air chute 300 to generate an air flow through the air chute 300. A stator blade 500 is further disposed between the axial fan 400 and the air outlet 320, the stator blade 500 includes a stator hub 510 and a plurality of guide blades 520, the plurality of guide blades 520 are disposed at intervals along a circumferential direction of the stator hub 510, and the stator blade 500 is disposed in a flow-through region of an air flow generated by the axial fan 400 to guide the air flow, so as to guide the air flow to move in an up-and-down direction. The air flow is guided by the stator vane 500 to reduce the rotation speed of the air flow, so that the air pressure is maintained, and the noise is not increased while the CADR value of the air cleaner is increased. The stator blades 500 and the axial flow fan 400 are arranged at intervals, a second distance exists between the stator blades 500 and the axial flow fan 400 along the up-down direction, and the range of the second distance is 8% -15% of the diameter of the axial flow fan 400. The air purifier has compact structure and smaller volume of the whole machine.

In one embodiment, the axial fan 400 is spaced from the air duct 300 by less than 0.5% of the diameter of the air duct 300. Specifically, in one embodiment, the diameter of the air duct 300 is 262mm, and the gap between the axial fan 400 and the air duct 300 is 1 mm. Therefore, high wind pressure and high wind volume can be effectively kept.

In one embodiment, the rim of the air inlet 310 is provided with a bell-shaped flow guide 600, the bell-shaped flow guide 600 is arranged gradually expanding from top to bottom, and the section radius R of the bell-shaped flow guide 600 is 5% -15% of the diameter of the air duct 300. If the bell-shaped drainage part 600 without the air inlet is arranged, the phenomenon of obvious pulse contraction can occur when the air flow enters the air inlet, the noise is increased, and the air volume is reduced. In the present example of the air duct 300, the radius of the rounded corners of the air inlet 310 preferably exceeds 14% of the diameter of the air duct 300. When the radius of the fillet is equal to 14% of the diameter of the air duct 300, the air quantity can be improved by about 10%. And when the radius of the fillet is equal to 5% of the diameter of the air duct 300, the air quantity can be improved by about 4%. Therefore, the radius of the fillet is 5% -15% of the diameter of the air duct 300, so that the ventilation efficiency and the noise control are kept at a better level.

In one embodiment, a filter screen 700 is further included, and the filter screen 700 is disposed between the intake vent 310 and the axial fan 400. After the air duct 300 is arranged in the vertical direction, the air flow direction in the air purifier is consistent, so the filter screen 700 can adopt a common square or round filter screen 700 without other special shapes such as a tubular filter screen 700, and the filter screen 700 is transversely arranged, so the height of the air purifier is reduced, the structure of the air duct 300 is compact, and the volume is reduced.
