[0042] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0043] The fan assembly 1 according to an embodiment of the present utility model is described below with reference to the accompanying drawings.

[0044] like Figure 1-Figure 5 As shown, the fan assembly 1 according to the embodiment of the utility model includes a housing 10, a wind wheel 20, a motor, and a diverter device.

[0045] The shell 10 defines a accommodating chamber 11, an air inlet channel 12 and an air outlet channel 13. The accommodating chamber 11 is connected between the air inlet channel 12 and the air outlet channel 13. The wind wheel 20 is rotatably disposed in the accommodating chamber 11. The motor is connected to the wind wheel 20 to drive the wind wheel 20 to rotate. When the wind wheel 20 rotates, the wind wheel 20 can drive the air to enter the accommodating chamber 11 along the air inlet channel 12, drive the air in the accommodating chamber 11 into the air outlet channel 13 and flow to the designated area along the air outlet channel 13, so as to introduce air into the designated area.

[0046] The diversion device includes a plurality of diversion plates 31 and a driving assembly. The plurality of diversion plates 31 are rotatably disposed in the air outlet channel 13 and are disposed near the outlet of the air outlet channel 13 so as to divide the air outlet section of the air outlet channel 13 near its outlet into a plurality of diversion channels, thereby being able to guide the flow of air in the air outlet channel 13 so that the air in the air outlet channel 13 can flow evenly from the outlet of the air outlet channel 13 to the designated area along the diversion plates 31.

[0047] The driving assembly is used to drive the plurality of diverter plates 31 to rotate. When the diverter plates 31 rotate, the flow direction of the air at the outlet of the air outlet channel 13 can be guided, thereby changing the flow direction of the air in the air outlet channel 13, so that the air in the air outlet channel 13 flows to a designated area along a certain direction. When the motor drives the wind wheel 20 to rotate, some noise will be generated, and the generated noise will enter the air outlet channel 13 with the air. While the diverter plates 31 change the air flow direction, the diverter plates 31 can also change the transmission direction of the noise in the air outlet channel 13. In this way, by discharging the air in a direction away from the user, the noise generated at the wind wheel 20 can be transmitted in a direction away from the user, thereby meeting the noise reduction requirements and improving the user's hearing comfort.

[0048] Therefore, according to the fan assembly 1 of the embodiment of the utility model, by setting a rotatable diverter plate 31, it is possible to change the air outlet direction of the fan assembly 1 and the propagation direction of the noise, thereby causing the noise to propagate in a direction away from the user, so as to achieve noise reduction and improve the user's auditory comfort. At the same time, the diverter plate 31 is set in the air outlet channel 13 and will not occupy the external space of the fan assembly 1, thereby facilitating the miniaturization design of the fan assembly 1.

[0049] The fan assembly 1 according to a specific embodiment of the utility model is described below with reference to the accompanying drawings.

[0050] In some specific embodiments of the present invention, Figure 1-Figure 5 As shown, the wind turbine assembly 1 includes a housing 10, a wind wheel 20, a motor, and a flow diversion device.

[0051] In some embodiments of the present invention, Figure 3 As shown, the multiple diverter plates 31 include at least a first diverter plate 311 and a second diverter plate 312. The first diverter plate 311 and the second diverter plate 312 are arranged at intervals in the width direction of the air outlet channel 13. When the air flows along the air outlet channel 13, the first diverter plate 311 and the second diverter plate 312 can jointly guide the flow of air in the air outlet channel 13, so as to fully guide the air in the air outlet channel 13, so that the air in the air outlet channel 13 can flow to the designated area along the first diverter plate 311 and the second diverter plate 312, thereby causing the noise in the air outlet channel 13 to propagate along the designated direction, thereby achieving noise reduction of the fan assembly 1.

[0052] like Figure 6As shown, in this embodiment, the width of the air outlet channel 13 extends in the up-down direction, a plurality of guide plates 41 are arranged at intervals in the up-down direction, the first diverter plate 311 is located above the second diverter plate 312, the first diverter plate 311 and the second diverter plate 312 divide the air outlet section into a plurality of diverter channels, and the plurality of diverter channels are sequentially divided from top to bottom into a first diverter channel 141, a second diverter channel 142 and a third diverter channel 143. Specifically, the first diverter plate 311 and the upper side wall of the air outlet channel 13 define the first diverter channel 141, the first diverter plate 311 and the second diverter plate 312 define the second diverter channel 142, and the second diverter plate 312 and the lower side wall of the air outlet channel 13 define the third diverter channel 143, and the air in the air outlet channel 13 can flow to the designated area along the first diverter channel 141, the second diverter channel 142 and the third diverter channel 143.

[0053] In some optional embodiments of the present invention, Figure 6 As shown, the diversion device has a first diversion state. In the first diversion state, the extension direction of the first diversion plate 311 and the second diversion plate 312 is parallel to the extension direction of the air outlet channel 13. At this time, the air in the air outlet channel 13 can flow to the designated area along the first diversion plate 311 and the second diversion plate 312 at a faster speed, and a strong wind can be formed in the designated area.

[0054] like Figure 6 As shown, the extension direction of the air outlet channel 13 extends along the front-to-back direction. At this time, the air in the air outlet channel 13 is discharged forward to guide the air to the area on the front side of the fan assembly 1.

[0055] In some specific embodiments of the present invention, Figure 7 As shown, the diversion device also has a second diversion state. In the second diversion state, the first diversion plate 311 and the second diversion plate 312 both extend from the inside to the outside along the extension direction of the air outlet channel 13 toward the direction close to the accommodating chamber 11. Under the guidance of the first diversion plate 311 and the second diversion plate 312, the air in the air outlet channel 13 flows from the inside to the outside along the first diversion plate 311 and the second diversion plate 312 in the direction close to the accommodating chamber 11 to guide the air to the designated area.

[0056] It needs to be explained here that the inside and outside mentioned here are relative to the first diverter plate 311 and the second diverter plate 312. The side of the first diverter plate 311 and the second diverter plate 312 facing the inlet of the air outlet channel 13 is the inner side, and the other side of the first diverter plate 311 and the second diverter plate 312, that is, the side facing the outlet of the air outlet channel 13 is the outer side.

[0057] In some embodiments, Figure 7As shown, the air outlet channel 13 extends in the front-to-back direction, the inlet of the air outlet channel 13 is located at the rear end of the air outlet channel 13, the outlet of the air outlet channel 13 is located at the front end of the air outlet channel 13, and the accommodating chamber 11 is located below the air outlet channel 13. In the second diversion state, the first diversion plate 311 and the second diversion plate 312 extend downward from the back to the front, so that the air in the air outlet channel 13 can be discharged forward and downward, and then the air is guided to the downward area on the front side of the fan assembly 1.

[0058] Among them, the downward inclination angles of the first diverter plate 311 and the second diverter plate 312 relative to the front-to-back direction can be the same or different. By adjusting the inclination angles of the first diverter plate 311 and the second diverter plate 312, the sizes of the inlets and outlets of the first diverter channel 141, the second diverter channel 142 and the third diverter channel 143 can be changed.

[0059] For example, when the downward inclination angle of the first diverter plate 311 relative to the front-to-back direction is greater than the inclination angle of the second diverter plate 312, the inlet of the second diverter channel 142 is larger than the outlet of the second diverter channel 142, so that when the air flows forward and downward along the second diverter channel 142 to the designated area, a stronger wind force can be formed.

[0060] In some specific embodiments of the present invention, Figure 8 As shown, the diversion device also has a third diversion state. In the third diversion state, the first diversion plate 311 and the second diversion plate 312 both extend from the inside to the outside along the extension direction of the air outlet channel 13 in a direction away from the accommodating chamber 11. Under the guidance of the first diversion plate 311 and the second diversion plate 312, the air in the air outlet channel 13 flows from the inside to the outside along the first diversion plate 311 and the second diversion plate 312 in a direction away from the accommodating chamber 11 to guide the air to a designated area.

[0061] In some embodiments, Figure 8 As shown, the air outlet channel 13 extends along the front and rear directions, the inlet of the air outlet channel 13 is located at the rear end of the air outlet channel 13, the outlet of the air outlet channel 13 is located at the front end of the air outlet channel 13, and the accommodating chamber 11 is located below the air outlet channel 13. In the third diversion state, the first diverter plate 311 and the second diverter plate 312 extend upward from the back to the front, so that the air in the air outlet channel 13 can be discharged forward and upward, and then the air is guided to the upper area on the front side of the fan assembly 1.

[0062] The first diverter plate 311 and the second diverter plate 312 may be inclined upward at the same angle relative to the front-rear direction or at different angles. By adjusting the inclination angles of the first diverter plate 311 and the second diverter plate 312, the sizes of the inlets and outlets of the first diverter channel 141, the second diverter channel 142, and the third diverter channel 143 may be changed.

[0063] For example, when the upward inclination angle of the first diverter plate 311 relative to the front-to-back direction is smaller than the inclination angle of the second diverter plate 312, the inlet of the second diverter channel 142 is larger than the outlet of the second diverter channel 142, so that when the air flows along the second diverter channel 142 to the forward and upward part, a stronger wind force can be formed.

[0064] In some specific embodiments of the present invention, Fig. 9 As shown, the diversion device also has a fourth diversion state. In the fourth diversion state, the first diversion plate 311 and the second diversion plate 312 extend from the inside to the outside along the extension direction of the air outlet channel 13 in a direction away from each other, thereby forming a diffuse air outlet. This is convenient for forming a soft air outlet on the one hand, and for dispersing vibrations in the air on the other hand, thereby achieving noise reduction.

[0065] In some embodiments, Fig. 9 As shown, the air outlet channel 13 extends in the front-to-back direction, the inlet of the air outlet channel 13 is located at the rear end of the air outlet channel 13, the outlet of the air outlet channel 13 is located at the front end of the air outlet channel 13, the accommodating chamber 11 is located below the air outlet channel 13, and the second diverter plate 312 is located below the first diverter plate 311. In the fourth diversion state, the first diverter plate 311 extends upward from the back to the front, and the second diverter plate 312 extends downward from the back to the front. The distance between the rear ends of the first diverter plate 311 and the second diverter plate 312 is smaller than the distance at the front end. In this way, when the air flows out along the first diverter plate 311 and the second diverter plate 312, a diffused air outlet can be formed between the first diverter plate 311 and the second diverter plate 312, so that the air can be dispersed and guided to the designated area, thereby forming a soft air outlet.

[0066] Among them, the upward inclination angle of the first diverter plate 311 relative to the front-to-back direction and the downward inclination angle of the second diverter plate 312 relative to the front-to-back direction can be the same or different. By adjusting the inclination angles of the first diverter plate 311 and the second diverter plate 312, the sizes of the inlets and outlets of the first diverter channel 141, the second diverter channel 142 and the third diverter channel 143 can be changed, thereby changing the degree of diffusion of the air when flowing along the second diverter channel 142.

[0067] In some optional embodiments of the present utility model, compared with the first diverter plate 311, the second diverter plate 312 is arranged closer to the accommodating chamber 11, and the first diverter plate 311 can swing between the first position and the second position. In the first position, the first diverter plate 311 extends from the inside to the outside in the direction close to the accommodating chamber 11 along the extension direction of the air outlet channel 13. At this time, the air in the air outlet channel 13 can flow outward along the first diverter plate 311 in the direction close to the accommodating chamber 11 to guide the air to the designated area. In the second position, the first diverter plate 311 extends from the inside to the outside in the direction away from the accommodating chamber 11 along the extension direction of the air outlet channel 13. At this time, the air in the air outlet channel 13 can flow outward along the first diverter plate 311 in the direction away from the accommodating chamber 11 to guide the air to the designated area.

[0068] In some specific embodiments of the utility model, in the first position state, the angle between the first diverter plate 311 and the extension direction of the air outlet channel 13 is 15° to 20°. Specifically, the angle between the first diverter plate 311 and the extension direction of the air outlet channel 13 can be 15°, 16°, 17°, 18°, 19° or 20°.

[0069] like Figure 7 As shown, at this time, the first diverter plate 311 is in the first position, and the first diverter plate 311 extends from back to front and downward, and the air in the air outlet channel 13 can flow forward and downward along the first diverter plate 311. By changing the angle between the first diverter plate 311 and the front-to-back direction, the forward and downward air outlet direction and distance of the fan assembly 1 can be changed, thereby directing the air to a designated area.

[0070] In the second position, the angle between the first diverter plate 311 and the extension direction of the air outlet channel 13 is 5° to 10°. Specifically, the angle between the first diverter plate 311 and the extension direction of the air outlet channel 13 can be 5°, 6°, 7°, 8°, 9° or 10°.

[0071] like Figure 8 , Fig. 9 As shown, at this time, the first diverter plate 311 is in the second position, and the first diverter plate 311 extends from back to front and upward, and the air in the air outlet channel 13 can flow forward and upward along the first diverter plate 311. By changing the angle between the first diverter plate 311 and the front-to-back direction, the forward and upward air outlet direction and distance of the fan assembly 1 can be changed, thereby directing the air to a designated area.

[0072] In some optional embodiments of the utility model, compared with the first splitter plate 311, the second splitter plate 312 is arranged closer to the accommodating chamber 11, and the second splitter plate 312 can swing between the third position and the fourth position. In the third position, the second splitter plate 312 extends from the inside to the outside along the extension direction of the air outlet channel 13 in the direction away from the accommodating chamber 11. At this time, the air in the air outlet channel 13 can flow outward along the second splitter plate 312 in the direction away from the accommodating chamber 11 to guide the air to the designated area. In the fourth position, the second splitter plate 312 extends from the inside to the outside along the extension direction of the air outlet channel 13 in the direction close to the accommodating chamber 11. At this time, the air in the air outlet channel 13 can flow outward along the second splitter plate 312 in the direction close to the accommodating chamber 11 to guide the air to the designated area.

[0073] In some specific embodiments of the present invention, in the third position, the angle between the second splitter plate 312 and the extension direction of the air outlet channel 13 is 15-20°. Specifically, the angle between the second splitter plate 312 and the extension direction of the air outlet channel 13 can be 15°, 16°, 17°, 18°, 19° or 20°.

[0074] like Figure 8 As shown, at this time, the second diverter plate 312 is in the third position, and the second diverter plate 312 extends from back to front and upward, and the air in the air outlet channel 13 can flow forward and upward along the second diverter plate 312. By changing the angle between the second diverter plate 312 and the front-to-back direction, the forward and upward air outlet direction and distance of the fan assembly 1 can be changed, thereby directing the air to a designated area.

[0075] In the fourth position, the angle between the second diverter plate 312 and the extension direction of the air outlet channel 13 is 5° to 10°. Specifically, the angle between the second diverter plate 312 and the extension direction of the air outlet channel 13 can be 5°, 6°, 7°, 8°, 9° or 10°.

[0076] like Figure 7 , Fig. 9 As shown, at this time, the second diverter plate 312 is in the fourth position, and the second diverter plate 312 extends from back to front and downward, and the air in the air outlet channel 13 can flow forward and downward along the second diverter plate 312. By changing the angle between the second diverter plate 312 and the front-to-back direction, the forward and downward air outlet direction and distance of the fan assembly 1 can be changed, thereby directing the air to a designated area.

[0077] In some specific embodiments, Figure 7As shown, when the diverter device is in the second diverter state, the first diverter plate 311 is in the first position and the second diverter plate 312 is in the fourth position. At this time, the angle between the first diverter plate 311 and the front-to-back direction is greater than the angle between the second diverter plate 312 and the front-to-back direction, so that the inlet of the second diverter channel is greater than the outlet, so that when the air in the air outlet channel 13 flows forward and downward along the first diverter plate 311 and the second diverter plate 312, a strong wind can be formed and the wind can be directed to the downward area on the front side of the fan assembly 1.

[0078] In other specific embodiments, Figure 8 As shown, when the diverter device is in the third diverter state, the first diverter plate 311 is in the second position, and the second diverter plate 312 is in the third position. At this time, the angle between the first diverter plate 311 and the front-to-back direction is smaller than the angle between the second diverter plate 312 and the front-to-back direction, so that the inlet of the second diverter channel is larger than the outlet, so that when the air in the air outlet channel 13 flows forward and upward along the first diverter plate 311 and the second diverter plate 312, a strong wind can be formed and the wind can be directed to the upper area on the front side of the fan assembly 1.

[0079] In some other embodiments, Fig. 9 As shown, when the flow diverter device is in the fourth flow diverter state, the first flow diverter plate 311 is in the second position, and the second flow diverter plate 312 is in the fourth position, so that the first flow diverter plate 311 and the second flow diverter plate 312 form a diffused second flow diverter channel 142, thereby facilitating the formation of diffused air outlet at the front area of ​​the fan assembly 1. In some other embodiments, the flow diverter device also includes a fifth flow diverter state, when the first flow diverter plate 311 is in the first position, the second flow diverter plate 312 is in the third position, and the inlet of the second flow diverter channel 142 is larger than the outlet, so as to form a strong wind and direct the wind to the front side of the fan assembly 1.

[0080] In some optional embodiments of the present invention, the driving assembly includes two driving motors, namely a first driving motor and a second driving motor. The first driving motor cooperates with the first diverter plate 311 to drive the first diverter plate 311 to rotate. When the first driving motor drives the first diverter plate 311 to rotate, the extension direction of the first diverter plate 311 changes, so that the first diverter plate 311 can be switched between the first position and the second position. The second driving motor cooperates with the second diverter plate 312 to drive the second diverter plate 312 to rotate. When the second driving motor drives the second diverter plate 312 to rotate, the extension direction of the second diverter plate 312 changes, so that the second diverter plate 312 can be switched between the third position and the fourth position.

[0081] Specifically, the first diverter plate 311 takes its center as the rotation center. Here, the extension direction of the first diverter plate 311 along the air outlet channel 13 is taken as the initial state. When the first driving motor drives the first diverter plate 311 to rotate clockwise, the first diverter plate 311 extends from back to front upward; when the first driving motor drives the first diverter plate 311 to rotate counterclockwise, the first diverter plate 311 extends from back to front downward. By changing the rotation angle of the first diverter plate 311, the angle between the first diverter plate 311 and the extension direction of the air outlet channel 13 can be changed.

[0082] The second diverter plate 312 takes its center as the rotation center, and here the extension direction of the second diverter plate 312 along the air outlet channel 13 is taken as the initial state. When the second driving motor drives the second diverter plate 312 to rotate clockwise, the second diverter plate 312 extends from back to front upward; when the second driving motor drives the second diverter plate 312 to rotate counterclockwise, the second diverter plate 312 extends from back to front downward. By changing the rotation angle of the second diverter plate 312, the angle between the second diverter plate 312 and the extension direction of the air outlet channel 13 can be changed.

[0083] In some other optional embodiments of the present invention, the driving assembly includes a first transmission member, a second transmission member and a switching part, the first diverter plate 311 includes a first transmission gear 26, the second diverter plate 312 includes a second transmission gear, and the switching part is used to adjust the matching state of the plurality of diverter plates 31 with the first transmission member and the second transmission member, so that the plurality of diverter plates 31 can switchably match with the first transmission member and the second transmission member. When the first transmission member is active, the first transmission gear 26 and the second transmission gear rotate in the same direction, and when the second transmission member is active, the first transmission gear 26 and the second transmission gear rotate in different directions.

[0084] In some embodiments, the first transmission member is a gear belt 25, the first transmission gear 26 and the second transmission gear are arranged at intervals in the up and down directions, the gear belt 25 is arranged circumferentially around the first transmission gear 26 and the second transmission gear and meshes with the first transmission gear 26 and the second transmission gear, and the drive motor also includes a driving member 28, the driving member 28 cooperates with the second transmission gear and is used to drive the second transmission gear to rotate. When the second transmission gear rotates, it can drive the gear belt 25 to move, and the gear belt 25 drives the first transmission gear 26 to rotate, so as to realize the first diverter plate 311 and the second diverter plate 312 to rotate in the same direction.

[0085] like Fig.11 , Fig.12As shown, the transmission belt includes a first meshing portion 251, a second meshing portion 252, a third meshing portion 253 and a fourth meshing portion 254, the first transmission gear 26 includes a first meshing matching portion and a second meshing matching portion, the first meshing matching portion meshes with the first meshing portion 251, the second meshing matching portion meshes with the second meshing portion 252, the second transmission gear includes a third meshing matching portion and a fourth meshing matching portion. The third meshing matching portion meshes with the third meshing portion 253, and the fourth meshing matching portion meshes with the fourth meshing portion 254.

[0086] When the gear belt 25 drives the first transmission gear 26 and the second transmission gear to rotate in the counterclockwise direction, the first meshing portion 251 meshes with the first meshing matching portion, and the fourth meshing portion 254 matches with the fourth meshing matching portion. At this time, when the gear belt 25 is active, the first transmission gear 26 and the second transmission gear rotate at different angular speeds. For example, when the first transmission gear 26 rotates 15°, the second transmission gear rotates 5°, or when the first transmission gear 26 rotates 20°, the second transmission gear rotates 10°, so that the first diverter plate 311 and the second diverter plate 312 rotate at different angular speeds when rotating in the same direction, so that when the first diverter plate 311 is in the first position, the second diverter plate 312 is in the fourth position, thereby realizing the second diversion state of the diversion device.

[0087] When the gear belt 25 drives the first transmission gear 26 and the second transmission gear to rotate in the clockwise direction, the second meshing portion 252 meshes with the second meshing matching portion, and the third meshing matching portion meshes with the fourth meshing matching portion. At this time, when the gear belt 25 is active, the first transmission gear 26 and the second transmission gear rotate at different angular speeds. For example, when the first transmission gear 26 rotates 5°, the second transmission gear rotates 15°, or when the first transmission gear 26 rotates 10°, the second transmission gear rotates 20°, so that the first diverter plate 311 and the second diverter plate 312 rotate at different angular speeds when rotating in the same direction, so that when the first diverter plate 311 is in the second position, the second diverter plate 312 is in the third position, thereby realizing the third diversion state of the diversion device.

[0088] The second transmission member is a rack, and the first transmission gear 26 and the second transmission gear are located on both sides of the rack. When the rack moves, it can drive the first transmission gear 26 and the second transmission gear to rotate in different directions, thereby realizing the rotation of the first diverter plate 311 and the second diverter plate 312 in different directions.

[0089] The second transmission member includes a fifth meshing portion and a sixth meshing portion, the first transmission gear 26 includes a fifth meshing matching portion, the fifth meshing matching portion meshes with the fifth meshing portion, the second transmission gear includes a sixth meshing matching portion, the sixth meshing matching portion meshes with the sixth meshing portion, when the rack moves, the first transmission gear 26 and the second transmission gear rotate in opposite directions at the same angular velocity, so that when the first diverter plate 311 is in the second state, the second diverter plate 312 is in the fourth state, thereby realizing the fourth diversion state of the diversion device.

[0090] In some embodiments of the present invention, Figure 3 As shown, the fan assembly 1 also includes a guide portion 40, which is arranged in the air outlet channel 13 and located upstream of the diverter plate 31. The guide portion 40 can guide the flow direction of the upstream air in the air outlet channel 13, so that the air in the air outlet channel 13 can smoothly flow along the guide portion 40 to the diverter plate 31 and flow from the outlet of the air outlet channel 13 to the designated area along the diverter plate 31.

[0091] Specifically, when the motor drives the wind wheel 20 to rotate, the wind wheel 20 will drive the air to flow from the air inlet channel 12 to the accommodating chamber 11, and flow along the accommodating chamber 11 to the air outlet channel 13. When the air flows in the air inlet channel 12, since the wind wheel 20 is arranged in the accommodating chamber 11, the wind wheel 20 cannot directly control the flow direction of the air in the air outlet channel 13. It can only indirectly drive the air in the air outlet channel 13 to flow from the outlet of the air outlet channel 13 to the designated area by driving the air in the accommodating chamber 11 to flow into the air outlet channel 13.

[0092] In this process, the guide portion 40 can guide the flow direction of the air flowing from the accommodating chamber 11 to the air outlet channel 13. The air in the accommodating chamber 11 enters the air outlet channel 13 from the inlet of the air outlet channel 13, flows along the guide portion 40 to the diverter plate 31 in the air outlet channel 13, and flows from the outlet of the air outlet channel 13 to the designated area along the diverter plate 31.

[0093] That is to say, by arranging the guide part 40 and the diverter plate 31 in the air outlet channel 13, the guide part 40 and the diverter plate 31 can guide the flow direction of the air into the air outlet channel 13 in turn, so that the air entering the air outlet channel 13 can flow from the outlet of the air outlet channel 13 to the designated area evenly and smoothly along the designated path, avoiding the formation of vortex in the air outlet channel 13, and facilitating the reduction of noise generated in the air outlet channel 13.

[0094] In some optional embodiments of the present invention, the guide portion 40 includes a guide plate 41, which is arranged upstream of the air outlet channel 13 so as to guide the air flowing from the accommodating chamber 11 into the air outlet channel 13, and guide the air to the diverter plate 31, so that the air can flow to the designated area along the diverter plate 31.

[0095] In other embodiments of the present invention, Figure 3 As shown, the guide portion 40 includes a plurality of guide plates 41, and the plurality of guide plates 41 are arranged at intervals in the width direction of the air outlet channel 13, so as to utilize the plurality of guide plates 41 to fully guide the flow direction of the air in the air outlet channel 13, thereby avoiding the formation of vortices in the air outlet channel 13 due to insufficient guidance of the air by the guide plates 41.

[0096] like Figure 3 As shown, in the present embodiment, the width of the air outlet channel 13 extends in the up-down direction, and a plurality of guide plates 41 are arranged at intervals in the up-down direction. Driven by the wind wheel 20, the air in the accommodating chamber 11 enters the air outlet channel 13 from the inlet of the air outlet channel 13. At this time, the plurality of guide plates 41 can jointly guide the air entering the air outlet channel 13, thereby facilitating the improvement of the air guiding efficiency and preventing the air entering the air outlet channel 13 from gathering in a certain place and affecting the flow of air in the air outlet channel 13.

[0097] In some embodiments, Figure 3 As shown, the first end of the guide plate 41 is bent toward the direction close to the wind wheel 20 and formed into an arc-shaped plate, and the second end of the guide plate 41 extends toward the direction of the diverter plate 31, so that when the wind wheel 20 drives the air in the accommodating chamber 11 to enter the air outlet channel 13 from the inlet of the air outlet channel 13, the first end of the guide plate 41 can control the flow direction of the air, so that the air can flow along the guide plate 41 to the diverter plate 31, and then the air can flow smoothly from the outlet of the air outlet channel 13 to the designated area along the diverter plate 31.

[0098] In some specific embodiments of the present invention, the guide portion 40 includes a plurality of guide plates 41, and the plurality of diverter plates 31 correspond one to one with the plurality of guide plates 41, so that when the guide member and the diverter plate 31 jointly guide the flow of air in the air outlet channel 13, the air in the air outlet channel 13 can flow toward the outlet of the air outlet channel 13 along a certain trajectory, thereby avoiding air turbulence in the air outlet channel 13, thereby facilitating the reduction of noise generation in the fan assembly 1.

[0099] like Figure 3As shown, in the present embodiment, the width direction of the air outlet channel 13 extends in the up-down direction, a plurality of guide plates 41 are arranged at intervals in the up-down direction, a plurality of diverter plates 31 are arranged at intervals in the up-down direction, and a plurality of guide plates 41 and a plurality of diverter plates 31 correspond one to one in the front-to-back direction (it should be understood here that the above-mentioned direction limitation is only for the convenience of describing the accompanying drawings, and will not limit the actual setting position and direction of the fan assembly 1). When the wind wheel 20 rotates and drives the air in the accommodating chamber 11 to flow into the air outlet channel 13, the air flows from back to front along the circumference of the wind wheel 20 toward the guide plate 41, and flows along the guide plate 41 to the diverter plate 31, and flows along the diverter plate 31 from the outlet of the air outlet channel 13 to the designated area.

[0100] Make multiple guide plates 41 and multiple diverter plates 31 correspond one by one along the front-to-back direction, so that the guide plates 41 can smoothly and evenly guide the air to the diverter plates 31, avoid air gathering at a certain guide plate 41, avoid multiple air streams colliding with each other, and thus facilitate ensuring the stable flow of air in the air outlet channel 13, and facilitate reducing the generation of noise in the air outlet channel 13.

[0102] The inlet of the air inlet channel 12 is a fresh air inlet 121. The filter 50 is disposed in the air inlet channel 12. The filter 50 can filter the air in the air inlet channel 12 that passes through the filter 50, thereby ensuring the cleanliness of the air entering the accommodating chamber 11, preventing unclean air from polluting the wind wheel 20 in the accommodating chamber 11, and thereby ensuring the cleanliness of the air in the air outlet channel 13, so as to provide clean air to the designated area. Among them, the outlet of the air outlet channel 13 is a fresh air outlet 131, and the air in the air outlet channel 13 can flow from the fresh air outlet 131 to the designated area along the diverter plate 31.

[0103] In some examples, the filter element 50 is placed obliquely in the air inlet channel 12, and the filter element 50 divides the air inlet channel 12 into a first air inlet chamber and a second air inlet chamber. The first air inlet chamber is connected to the fresh air inlet 121, and the second air inlet chamber is connected to the accommodating chamber 11. The air entering the first air inlet chamber from the fresh air inlet 121 enters the second air inlet chamber after being filtered by the filter element 50, and enters the accommodating chamber 11 along the second air inlet chamber.

[0104] Among them, the filter element 50 is placed obliquely in the air inlet channel 12 to increase the contact area between the filter element 50 and the air in the first air inlet chamber, so as to improve the filtering efficiency of the filter element 50 on the air in the first air inlet chamber, so that the filter element 50 can fully and quickly filter the air in the first air inlet chamber.

[0105] In some examples, a side wall of the shell 10 is provided with an access port, which is connected to the air inlet channel 12. The filter 50 can be pulled out from the access port and disposed in the air inlet channel 12 to facilitate cleaning or replacement of the filter 50.
