[0030] Reference below Figures 1 to 7 The wind guide wheel installation structure according to the first embodiment of the present invention is described.

[0031] The wind guide wheel installation structure includes: a fan front shell 101, wherein a middle hole 102 is provided in the middle, a guide ring 103 is provided on the inner wall of the middle hole 102, and the guide ring 103 is coaxially arranged with the middle hole 102; a wind guide motor 104, which is fixedly connected to the rear side of the fan front shell 101, and the output shaft of the wind guide motor 104 is coaxially arranged with the guide ring 103; a rotating connecting member 105, the rear side of which is fixedly connected to the output shaft of the wind guide motor 104; a rotating disk 106, which is arranged at the front of the fan shell 101 On the front side, a rotating connection hole 107 is provided in the middle of the turntable 106, and the rotating connection hole 107 is sleeved on the front side of the rotating connection member 105, and the rotating connection member 105 and the rotating connection hole 107 are relatively fixed circumferentially. The rear side of the turntable 106 is provided with a guide assembly connected to the guide ring 103, and the guide assembly and the guide ring 103 are relatively fixed axially, and the guide assembly and the guide ring 103 rotate circumferentially relative to each other; the guide wheel 108 is fixedly connected to the front side of the turntable 106.

[0032] A turntable 106 is added between the output shaft of the air guide motor 104 and the air guide wheel 108. The output shaft of the air guide motor 104 drives the turntable 106 and the air guide wheel 108 to rotate through the rotating connecting piece 105. A guide assembly is arranged on the turntable 106, and a guide ring 103 is arranged on the front shell 101 of the fan. The guide assembly and the guide ring 103 are connected in a guiding manner. The guide ring 103 limits the shaking of the turntable 106. After the air guide wheel 108 is installed on the turntable 106, the shaking amplitude can be reduced.

[0033] The rotating connecting member 105 and the rotating connecting hole 107 are fixed in the circumferential direction, driving the rotating disk 106 to rotate. A certain gap is allowed between the rotating connecting member 105 and the rotating connecting hole 107, which does not affect the rotation of the rotating disk 106 and reduces the installation requirements for the air guide motor 104. The connection hole on the rotating connecting member 105 that is sleeved on the output shaft of the air guide motor 104 and the processing matching accuracy of the output shaft of the air guide motor 104 do not need to be too high.

[0034] In some specific embodiments of the present invention, the guide assembly includes at least two limit columns 201 arranged along the front-to-back direction, all of the limit columns 201 are evenly distributed on the inner side of the guide ring 103 along the axis of the guide ring 103, the limit columns 201 are arranged on the side of the guide ring 103, and at least one of the limit columns 201 has a snap portion 202 at its end, and the snap portion 202 is snapped to the rear side of the guide ring 103, and a protruding ring 109 is provided on the front side of the guide ring 103, and the protruding ring 109 protrudes from the front side of the fan front housing 101, and a disk side wall 208 is provided on the rear side of the outer periphery of the turntable 106, and the disk side wall 208 is sleeved on the outer side of the outer wall of the protruding ring 109.

[0035] The buckle portion 202 and the front wall of the rotating disk 106 are used for axial fixation of the rotating disk 106. The rotating disk 106 is inserted into the guide ring 103 from the front side of the guide ring 103. The guide ring 103 compresses the buckle portion 202 inward. When the buckle portion 202 extends into the rear side of the guide ring 103, the buckle portion 202 rebounds and clamps the rear side of the guide ring 103. The front wall of the rotating disk 106 restricts the rotating disk 106 from further extending, and the installation is simple. The disk side wall 208 of the rotating disk 106 is sleeved on the outer side of the protruding ring 109 to achieve radial positioning of the rotating disk 106, reduce the deviation of the rotating disk 106 when rotating, and limit the shaking of the rotating disk 106. The buckle portion 202, the disk side wall 208 and the guide ring 103 have more contact points, and the effect of limiting shaking is better.

[0036] In some specific embodiments of the present invention, a plurality of slide posts 110 are evenly spaced on the outer wall of the protruding ring 109, and the disc side wall 208 is disposed outside the slide posts 110. The slide posts 110 are in contact with the disc side wall 208, so that the contact area between the disc side wall 208 and the protruding ring 109 is reduced, thereby reducing the friction between the disc 106 and the protruding ring 109 while better limiting the shaking of the rotating disc 106.

[0037] In some specific embodiments of the present invention, at least one of the limit columns 201 is provided with a first screw hole 203 on the rear side, and a limit screw is threadedly connected to the first screw hole 203, and the head of the limit screw is provided on the rear side of the guide ring 103. When only the buckle clamps the inner side of the guide ring 103, when the turntable 106 and the air guide wheel 108 are pulled out from the front side with force, the buckle may be disengaged, causing the turntable 106 and the air guide wheel 108 to be pulled out, exposing the fan blades, which is more dangerous. The limit screw is installed on the turntable 106 to clamp the rear side of the guide ring 103, so that the turntable 106 and the air guide wheel 108 cannot be pulled out from the front side, thereby improving safety. A gasket can be worn on the limit screw to increase the contact area between the screw head and the guide ring 103.

[0038] In some specific embodiments of the present invention, the rotating disk 106 is provided with a plurality of second screw holes 204, and the wind guide wheel 108 is provided with a plurality of mounting holes, and the plurality of mounting holes are arranged opposite to the plurality of second screw holes 204. The wind guide wheel 108 and the rotating disk 106 are fixed together with screws, and the rear side surface of the middle part of the wind guide wheel 108 abuts against the front side surface of the rotating disk 106.

[0039] In some specific embodiments of the present invention, a plurality of positioning posts 206 are provided on the front side of the rotating disk 106, and a plurality of positioning holes are provided on the front side of the wind guide wheel 108, and the plurality of positioning holes are connected one-to-one with the plurality of positioning posts 206. The positioning holes and the positioning posts 206 are used to maintain the circumferential positioning of the rotating disk 106 and the wind guide wheel 108, so as to prevent the connecting screws of the rotating disk 106 and the wind guide wheel 108 from loosening after the rotation direction of the wind guide wheel 108 changes multiple times.

[0040] In some specific embodiments of the present invention, the rotating connection hole 107 is cross-shaped, and the cross-shaped rotating connection hole 107 can drive the rotating disk 106 to rotate in the circumferential direction. The rotating connection hole 107 can also be a triangle, a quadrilateral, a hexagon, etc., or a platform is set in the circular hole, etc., which can drive the rotating disk 106 to rotate in the circumferential direction.

[0041] In some specific embodiments of the present invention, at least two slots 111 are provided on the wind guide wheel 108, and the slots 111 extend circumferentially along the axis of the wind guide wheel 108. A cover 301 is connected to the front side of the wind guide wheel 108, and at least two hooks are provided on the rear side of the cover 301, and the hooks are hooked in the slots 111 one by one. An insertion port 112 is provided at the head end of the slot 111, and the width of the insertion port 112 is greater than the width of the slot 111. The hook is inserted into the slot 111 through the insertion port 112, and the hook is slidably connected to the slot 111, and the cover 301 covers the middle part of the wind guide wheel 108. Since the rotation connection hole 107, the mounting hole, etc. are exposed in the middle part of the wind guide wheel 108, the cover 301 is installed on the front side of the wind guide wheel 108 for aesthetics. The cover 301 is provided with a hook. The hook is inserted into the slot 111 from the insertion port 112 and the cover 301 is rotated so that the hook can be stuck in the slot 111 and cannot be removed.
