DETAILED DESCRIPTION
[0021] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.
[0022] Embodiment 1:
[0023] like Figure 1-5 As shown, Figure 1 This is a schematic diagram of the overall structure of an improved direct-connected centrifugal fan according to the first embodiment of the utility model. Figure 2 This is a schematic diagram of the connection between the motor and the fan blades of the first embodiment of the utility model.

Figure 5 It is a schematic diagram of the connection between the air outlet channel and the rotating shaft of the first embodiment of the utility model.
[0024] The utility model provides an improved direct-connected centrifugal fan: comprising a base plate 101, a vertical pole 102, a mounting ring 103, a motor 104, a fan blade 105 and a fan casing 106, and also comprising an air outlet device, wherein the air outlet device comprises an air outlet channel 108, a guide plate 109, a rotating shaft 110 and an adjustment component, wherein the adjustment component comprises a sliding block 111, an adjustment shaft 112 and a rotating member, wherein the rotating member comprises a threaded rod 115 and a rotating column 116, wherein the rotating column 116 also comprises an arc-shaped protrusion 117. The above-mentioned scheme solves the above-mentioned problem that when adjusting the air outlet direction, the adjustment plates need to be rotated in sequence, and several groups of adjustment plates cannot be rotated synchronously, resulting in an extremely troublesome air outlet adjustment process. It can be understood that the present scheme can also be used to solve the dust prevention problem of the centrifugal fan.
[0025] In this embodiment, through the cooperation of the adjustment component and the guide plate 109, the four groups of guide plates 109 can rotate synchronously around their respective rotating shafts 110, so that the wind outlet angle can be adjusted, and the effect of simultaneously adjusting multiple groups of guide plates 109 is achieved, thereby making the adjustment of the wind outlet angle more convenient.
[0026] The air outlet channel 108 is communicated with the fan housing 106, the rotating shaft 110 is fixedly installed in the air outlet channel 108, one side of the guide plate 109 is rotatably installed on the rotating shaft 110 through the adjustment assembly, and the rotating shaft 110 passes through the guide plate 109. The fan housing 106 is a cylindrical structure as a whole, and its interior is hollow. One side of the fan housing 106 is concave inward, the first through hole 107 is arc-shaped, and multiple groups of first through holes 107 are annularly distributed on the fan housing 106. The air outlet channel 108 is rectangular and hollow inside. There are four groups of guide plates 109 and rotating shafts 110, which are distributed in parallel at the outlet of the air outlet channel 108. The guide plates 109 are generally plate-shaped structures, and a notch is provided at the lower left corner of the guide plates 109. The adjustment component drives the four groups of guide plates 109 to move synchronously away from one side of the rotating shaft 110, so that the four groups of guide plates 109 rotate synchronously around their respective rotating shafts 110, thereby adjusting the wind outlet angle and achieving the effect of adjusting multiple groups of guide plates 109 at the same time, thereby making the adjustment of the wind outlet angle more convenient.
[0027] Secondly, a sliding groove 113 is provided on the side of the air outlet channel 108 close to the rotating shaft 110, and the sliding block 111 is slidably installed in the air outlet channel 108 through the rotating member and is located in the sliding groove 113. A circular hole 114 is provided on the sliding block 111; the adjustment shaft 112 is rotatably installed on the side of the guide plate 109 away from the rotating shaft 110, and one end of the adjustment shaft 112 is located in the circular hole 114. An internal threaded hole is provided in the middle of the sliding block 111. Each group of the guide plates A group of adjustment shafts 112 are provided on each plate 109. The diameter of the adjustment shafts 112 is smaller than the diameter of the circular hole 114. The rotating component enables the sliding block 111 to have a better moving effect. The rotating component drives the sliding block 111 to move along the sliding groove 113, so that the sliding block 111 drives the adjustment shafts 112 to move synchronously. The adjustment shafts 112 are connected to the guide plates 109 in rotation, thereby driving one side of multiple groups of guide plates 109 to move synchronously.
[0028] Again, the threaded rod 115 passes through the air outlet channel 108 and extends into the slide groove 113. The threaded rod 115 is threadedly connected to the sliding block 111. The rotating column 116 is fixedly installed on the threaded rod 115. The outer wall of the threaded rod 115 is provided with threads. The rotating column 116 is welded to the end of the threaded rod 115 away from the air outlet channel 108. The rotating column 116 drives the threaded rod 115 to rotate through the rotating rod. The rotation of the threaded rod 115 drives the sliding block 111 to move through the threaded connection, thereby achieving the movement effect of the sliding block 111.
[0029] Finally, the arc-shaped protrusions 117 are fixedly mounted on the rotating column 116 . The arc-shaped protrusions 117 are in multiple groups and are distributed in an annular manner on the outer wall of the rotating column 116 . The arrangement of the arc-shaped protrusions 117 makes it easier for the rotating column 116 to rotate.
[0030] In this embodiment, when the air outlet angle of the centrifugal fan needs to be adjusted, the rotating column 116 is rotated to drive the threaded rod 115 to rotate on the air outlet channel 108, and the threaded rod 115 is threadedly connected with the sliding block 111. Due to the limitation of the sliding groove 113, the rotation of the threaded rod 115 drives the sliding block 111 to move along the sliding groove 113. One side of the guide plate 109 is rotatably mounted on the rotating shaft 110, and the adjustment shaft 112 rotatably connected to the other side of the guide plate 109 is located In the circular hole 114 on the sliding block 111, the movement of the sliding block 111 drives the multiple groups of adjustment shafts 112 to move synchronously through the circular hole 114. The multiple groups of adjustment shafts 112 drive the multiple groups of guide plates 109 to rotate around their respective rotating shafts 110 through the rotation connection with the guide plates 109 until they rotate to a suitable angle, thereby adjusting the wind outlet angle and achieving the effect of adjusting the multiple groups of guide plates 109 at the same time, thereby making the adjustment of the wind outlet angle more convenient.

[0034] Among them, the rotating disk 201 is rotatably installed on the outside of the fan casing 106, and a second through hole 203 is provided on the rotating disk 201; the rotating handle 202 is fixedly installed on the rotating disk 201, and the rotating disk 201 is a disc-shaped structure. The rotating handle 202 is welded on the rotating disk 201. When the centrifugal fan is not in use, the rotating handle 202 is rotated to drive the rotating disk 201 to rotate on the fan casing 106, so that the position of the second through hole 203 is staggered with the first through hole 107, thereby preventing dust from entering the inside of the fan casing 106 through the first through hole 107 and the second through hole 203, thereby achieving the dust-proof effect of the centrifugal fan.
[0035] In this embodiment, when the centrifugal fan is not in use, the rotating handle 202 is rotated to drive the rotating disk 201 to rotate on the fan housing 106, so that the second through hole 203 is staggered with the first through hole 107, thereby preventing dust from entering the interior of the fan housing 106 through the first through hole 107 and the second through hole 203, thereby achieving the dust-proof effect of the centrifugal fan.
