In detail, in the present embodiment, the air outlet 112 is provided with a plurality of air supply directions, the air guiding member 12 is provided with a plurality of air guiding paths, the plurality of air guiding paths are arranged in one-to-one correspondence with the plurality of air supply directions, and the air outlet range of the first air duct 13 is arranged to cover all the air guiding paths of the air guiding member 12, so that when the first air duct 13 and the second air duct 14 obtain air sources at the same time, the air outlet 112 respectively sends out air supply flows to a plurality of directions. Thus, by arranging the air outlet 112 to have a plurality of air supply directions, and arranging a plurality of flow guide paths corresponding to the air supply directions one by one on the flow guide member 12, when the first air duct 13 and the second air duct 14 obtain the air source at the same time, the air outlet 112 respectively sends the air supply air flow to a plurality of directions, so that the air outlet coverage range of the air supply device using the air outlet structure 1 is further enhanced.

As the wind speed of the air flow is unevenly distributed and high, the problems of uneven air outlet, small air outlet working coverage range and low comfort experience degree of the existing air outlet duct can be seen. Fig. 17 is a schematic diagram of the flow path and the flow velocity of the air flow in Fluent software when the air outlet structure works, wherein the arrow represents the flow direction of the air flow, the trend of the line represents the flow path of the air flow, the color of the line represents the flow velocity of the air flow, the darker the color of the line represents the higher the flow velocity, and in combination with the foregoing information, it can be derived from fig. 17: 1. compared with the existing air outlet duct in fig. 16, after the air flow in the air outlet structure is arranged by the air outlet structure, the speed distribution of the air flow is obviously more uniform (a plurality of areas with different colors are not obvious to distinguish from each other when the analysis is carried out on the section of the air flow, the colors of the different areas are relatively similar, and the speed distribution of the air flow is relatively more uniform); 2. the line color of the outlet position in the air outlet structure is shallower than that of the air inlet position, namely the air flow speed in the air outlet structure is reduced compared with that of the air inlet position at the outlet position, so that the air flow is blown to a human body more gently. Therefore, the air flow distribution after being tidied by the air outlet structure is more dispersed uniformly and mildly, and particularly, an annular air curtain can be formed around a human body, so that air supply can be provided for the human body more uniformly and more mildly. In addition, the uniformly dispersed annular airflow is beneficial to uniformly changing the indoor temperature.

In other embodiments, the specific shape of the air outlet 112 and the number of air outlet directions may be appropriately adjusted according to the actual situation, for example: the air outlet 112 may also be configured as a hexagon, and the air guiding member 12 is correspondingly configured as an inverted six-sided pyramid, six faces of the six-sided pyramid are respectively configured in parallel with six sides of the air outlet 112, and each face of the six-sided pyramid is used for guiding the second air duct 14, that is, the six-sided pyramid has six guiding paths, and accordingly, six angular directions are separated in the radial direction of the air outlet 112 for air supply.

In further detail, in the present embodiment, the housing 11 includes a cylinder 113, the first air duct 13 and the second air duct 14 are both disposed in the cylinder 113, and the cylinder 113 and the cone base 121 of the flow guiding member 12 jointly surround to form an annular air outlet 112; the first air duct 13 is arranged in a spiral shape along the inner wall of the cylinder 113, the second air duct 14 is arranged at the middle position of the cylinder 113, the first air duct 13 is arranged to surround the second air duct 14, when the first air duct 13 obtains a wind source, the first air flow in the first air duct 13 blows towards the air outlet 112, and simultaneously, the first air flow blows in a spiral manner along the inner wall of the cylinder 113, so that the air outlet range of the first air duct 13 covers the air outlet 112 along the inner wall of the cylinder 113. In this way, the cone base 121 of the air guide piece 12 is nested with the edge of the cylinder 113, an annular slot is formed between the cylinder 113 and the cone base 121 of the air guide piece 12, namely, the cylinder 113 and the cone base 121 of the air guide piece 12 jointly encircle to form an annular air outlet 112, when the first air duct 13 obtains a wind source, the first air flow in the first air duct 13 blows towards the air outlet 112, and simultaneously, the first air flow blows spirally along the inner wall of the cylinder 113, namely, the movement track of the first air flow covers the whole circumference of the cylinder 113, so that the air outlet range of the first air duct 13 covers the air outlet 112 along the inner wall of the cylinder 113, and as all the air guide paths of the air guide piece 12 pass through the air outlet 112, the effect that the air outlet range of the first air duct 13 is set to cover all the air guide paths of the air guide piece 12 is realized; in addition, the first air duct 13 arranged in a spiral shape guides the first air flow to be spirally blown, so that the first air flow is outwardly scattered and blown by 360 degrees from the air outlet 112, and the air quantity distribution is more uniform.

In this embodiment, the second air duct 14 is provided with a second shrinkage area, and the cross-sectional area of the second shrinkage area gradually decreases along the air outlet direction of the second air duct 14. Thus, when the second air flow moves along the second air duct 14 and passes through the second contraction area, the air volume of the second air flow is compressed along with the reduction of the space, so that the air speed of the second air flow is increased, that is, the air flow generated by the intersection and mixing of the first air flow and the second air flow can be blown farther, and the blowing coverage area is wider.
