In this embodiment, as shown in fig. 1 and 3-6, the fresh air device main body 1 includes a housing 102 and a first motor 103, the housing 102 has an air inlet 104 and an air outlet 101, an air duct 105 communicating the air inlet 104 and the air outlet 101 is disposed in the housing 102, a centrifugal wind wheel 3 is disposed in the air duct 105, the air outlet 101 is disposed in the circumferential direction of the housing 102 (that is, the air outlet 101 is disposed corresponding to a fan blade 301 of the centrifugal wind wheel 3, and an air outlet direction of the air outlet 101 is perpendicular to an axial direction of the centrifugal wind wheel 3), and the first motor 103 is configured to drive the centrifugal wind wheel 3 to rotate.

When the centrifugal wind wheel 3 rotates, air is discharged to the air duct 105 from the inner side to the outer side of the centrifugal wind wheel 3 under the action of centrifugal force, high pressure is formed in the air duct 105, so that the air is discharged from the air outlet 101 under the action of the high pressure, meanwhile, negative pressure is formed on the inner side of the centrifugal wind wheel 3, and the air is sucked into the inner side of the centrifugal wind wheel 3 from the air inlet 104 under the action of the negative pressure, so that continuous airflow is formed.

As shown in fig. 6, the distance between the centrifugal wind wheel 3 and the peripheral wall of the air duct 105 is gradually increased along the rotation direction of the centrifugal wind wheel 3 (in fig. 6, the centrifugal wind wheel 3 rotates in the counterclockwise direction), which is beneficial to reducing resistance, improving the smoothness of air flow, and reducing noise.

In some preferred embodiments, see fig. 7 and 8, the centrifugal wind wheel 3 includes a circular middle boss 302, and a plurality of blades 301 uniformly arranged along the circumferential direction; the fan blade 301 is similar to a C shape, along the rotating direction (anticlockwise direction in fig. 8) of the centrifugal wind wheel 3, the outer end b of the fan blade 301 is located on the front side of the inner end a of the fan blade 301 (the central point of the centrifugal wind wheel 3 is set to be o, namely the ob connecting line deviates from the oa connecting line by an angle along the rotating direction of the centrifugal wind wheel 3), the middle C of the fan blade 301 is located on the rear side of the inner end a of the fan blade 301 (namely the oa connecting line deviates from the oc connecting line by an angle along the rotating direction of the centrifugal wind wheel 3), the circumferential angle deviation between the outer end b of the fan blade 301 and the inner end a of the fan blade 301 is 6-8 degrees, and the circumferential angle deviation between the inner end a of the fan blade 301 and the middle C of the fan blade 301 is 6-8 degrees; the height of the upper end of the fan blade 301 (which does not represent the direction in actual use, based on the direction shown in fig. 7) gradually decreases from the outside to the inside (see fig. 7). Compared with the existing centrifugal wind wheel, the centrifugal wind wheel 3 with the shape generates less noise during working. Preferably, the circumferential angle deviation ^ boa between the outer side end b of the fan blade 301 and the inner side end a of the fan blade 301 is 7 °, the circumferential angle deviation ^ aoc between the inner side end a of the fan blade 301 and the middle c of the fan blade 301 is 7 °, and the noise reduction effect is good.

Preferably, the diameter of the middle boss 302 increases gradually from top to bottom, see fig. 9; a transition arc-shaped surface 304 is connected between the lower side of the middle boss 302 and a bottom plate 303 (a fan blade 301 is connected to the edge of the bottom plate 303) of the centrifugal wind wheel 3, and the upper side and the lower side of the transition arc-shaped surface 304 are respectively tangent to the peripheral surface of the middle boss 302 and the upper surface of the bottom plate 303. Therefore, when the centrifugal wind wheel works, after airflow flows into the centrifugal wind wheel 3 along the axial direction, the airflow direction is gradually changed under the guiding action of the outer peripheral surface of the middle boss 302 and the transition arc-shaped surface 304, and finally the airflow is discharged along the radial direction, so that the generation of vortex can be reduced, the airflow resistance can be reduced, the airflow flows more smoothly, and the noise can be further reduced.

In some preferred embodiments, see fig. 9, the central boss 302 is hollow, and the first motor 103 is disposed inside the housing 102 and protrudes into the inner cavity of the central boss 302. In fact, the first motor 103 may also be disposed on the outer layer of the casing 102, and the rotating shaft of the first motor extends into the inner side of the casing 102 to be connected with the centrifugal wind wheel 3, but compared with the foregoing manner, the first motor needs to occupy more space, which is not beneficial to improving the compactness of the fresh air device.

Preferably, referring to fig. 4 and 5, a purification chamber 106 is disposed in the housing 102, the air inlet 104 and the air duct 105 are both communicated with the purification chamber 106, a purification assembly 4 is disposed in the purification chamber 106, and the purification assembly 4 is used for purifying the air flow entering the air duct 105. The outside air is purified by the purifying component 4 before entering the air duct 105, so as to ensure the cleanness of the fresh air. Wherein, the purification component 4 can include at least one of a filtering component (such as a filter screen, an activated carbon filter, etc.) and a disinfecting component (such as an ultraviolet disinfecting lamp, an ozone generator, etc.).

In some embodiments, referring to fig. 5, the housing 102 defines a mounting opening 107 communicating with the purification chamber 106, and the purification assembly 4 is detachably inserted into the mounting opening 107.

In some preferred embodiments, see fig. 3, the housing 102 comprises a first housing portion 108, a second housing portion 109, and a third housing portion 110, wherein the first housing portion 108 and the second housing portion 109 are detachably connected (e.g., screwed, snapped, etc.) to enclose the air duct 105, and the second housing portion 109 and the third housing portion 110 are detachably connected (e.g., screwed, snapped, etc.) to enclose the purge chamber 106; to facilitate disassembly of the housing 102 for internal cleaning. Wherein, the second shell 109 is provided with an air passing hole 111 concentrically arranged with the centrifugal wind wheel 3, and the air passing hole 111 is used for communicating the purifying cavity 106 and the air duct 105; because the air passing hole 111 and the centrifugal wind wheel 3 are concentrically arranged, the path of the airflow flowing into the centrifugal wind wheel 3 from the purifying cavity 106 is shortest, and the airflow does not need to turn, so that the resistance is smaller, the flow is smoother, and the noise can be further reduced.

The embodiment of the application also provides an air conditioner, which comprises the fresh air device.

In summary, although the present invention has been described with reference to the preferred embodiments, the above-described preferred embodiments are not intended to limit the present invention, and those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, which are substantially the same as the present invention.
