[0030] The air outlet adjusting structure comprises a centering member and an air guide disc; the centering member is in a disc-shaped structure; three leg portions are detachably connected to the rim portion of the centering member; the leg portions are uniformly and circumferentially spaced apart; the first end of the leg portion is threadedly connected to the circumferential sidewall of the centering member; three mounting positions are arranged between the air guide cavity and the movable cavity; the mounting positions are in a hole shape; each mounting position is detachably connected to the corresponding leg portion; the second end of the leg portion is threadedly connected to the corresponding mounting position, so that the centering member is detachably connected to the inner cavity of the annular shell and is spaced apart from the blade.

[0031] A guide assembly is arranged between the centering member and the air guide disc; the guide assembly comprises a guide column and a guide hole; the guide column is inserted into and rotatably connected to the guide hole; the guide column is fixedly connected to the center position of the centering member; the guide hole is through the center position of the air guide disc; the air guide disc is arranged on the side of the centering member away from the air blowing device in a telescopic and rotatable manner. The end of the guide column inserted into the guide hole is provided with a limiting portion; the limiting portion is in a bolt structure; the outer diameter of the limiting portion is greater than the inner diameter of the guide hole; the limiting portion is used to limit the stroke of the movement of the air guide disc relative to the centering member.

[0032] An air outlet ring is arranged around the outer side of the air guide disc and is in communication with the inner cavity of the annular shell; the air outlet ring comprises a plurality of partition plates arranged in an annular array; the gap between two adjacent partition plates is in communication with the air guide cavity; the outer wall of each partition plate is in abutting or gap cooperation with the inner wall of the air guide cavity.

[0033] The inner wall of the air guide disc is inclined towards the blades by forming a tapered groove in the air guide disc. The inner wall of the air guide cavity is formed with an air guide curve which is curved towards the air guide disc. The air flow is generated by the rotating motor and the blades in the ring-shaped housing and the blowing device. The rotating motor drives the blades to rotate, and the external air flow passes through the mounting cavity, the movable cavity and the air guide cavity in turn. Under the guidance of the air guide curve and the inner wall of the air guide disc, the air flow is blown outward through the air outlet ring.

[0034] Three support tables are formed on the tapered surface of the inner wall of the groove. The support tables are uniformly spaced along the circumference of the air guide disc. The support tables are hollow. The top of the support table is provided with a support plate which is inclined along the circumference of the air guide disc. The support plate is provided with a track groove which extends along the circumference of the air guide disc. The foot of the centering piece is fixedly connected with a support column at the position of the support table.

[0035] The cooperation of the support table, the support plate, the track groove, the support column and the limiting piece enables the air guide disc to rotate while moving closer to or further away from the centering piece, thereby changing the distance between the air guide disc and the blades. The air guide disc at different positions is used to guide the air flow to achieve flexible adjustment of the air outlet range and the wind speed. The track groove is provided to limit the rotation stroke of the air guide disc. The support plate passes through the active space. The support column and the limiting piece cooperate to support the air guide disc, thereby limiting the air guide disc in the air guide cavity.

When the lower part of the support plate is located in the active space, the air guide disc is away from the blowing device and the distance between them is the largest.

[0036] When the air guide disc is close to the blowing device, a high pressure area is formed near the air guide disc, thereby increasing the wind speed and concentrating the air flow. When the air guide disc is away from the blowing device, the distance between the air guide disc and the blowing device increases, thereby reducing the wind speed and expanding the wind power coverage range. The user can adjust the wind speed and the coverage range according to the needs, thereby improving the convenience and comfort of use.

[0037] The groove cover is provided with a protective cover covering the opening thereof, and an annular array of a plurality of buckle structures is arranged at intervals between the edge portion of the air guide disc and the inner wall of the groove, the buckle structure comprising a hook portion and a clamping site, the clamping site being a slot structure, and the hook portion and the clamping site being buckled together; the hook portion is arranged on the air guide disc, and the clamping site is arranged in the groove, and the protective cover is used for limiting the limiting portion and each limiting member to avoid the limiting portion or the limiting member from being separated out due to misoperation.
