[0081] The following refers to Figures 1 - 29 Describe the air type regulation mechanism 100 and the fan 1000 according to the embodiments of the present invention.

[0082] Combined with Figures 1 to 3 And Figure 9 , according to the air type regulation mechanism 100 of the present invention, it includes: a bracket 110; an air duct adjusting member 120, the air duct adjusting member 120 includes a plurality of adjusting vanes 121, the plurality of adjusting vanes 121 are arranged along the circumferential direction of the bracket 110, each adjusting vane 121 is provided with a rotating part 1211 and a guiding part 1212, the rotating part 1211 is rotatably arranged on the bracket 110 so that the air duct adjusting member 120 can be switched between different states; a guiding ring 130, the guiding ring 130 is rotatable relative to the bracket 110, and the guiding ring 130 cooperates with the guiding parts of the plurality of adjusting vanes 121 to drive the plurality of adjusting vanes 121 to rotate synchronously when the guiding ring 130 rotates.

[0083] Specifically, the plurality of adjusting vanes 121 are evenly spaced along the circumferential direction of the bracket 110. The adjusting vane 121 is provided with a rotating part 1211 and a guiding part 1212. The adjusting vane 121 is rotatably connected to the bracket 110 through the rotating part 1211. At the same time, the air type regulation mechanism 100 is provided with a guiding ring 130. When the guiding ring 130 rotates relative to the bracket 110, the guiding ring 130 can drive the adjusting vane 121 to rotate synchronously relative to the bracket 110 through the guiding part 1212.

[0084] Furthermore, the air duct adjusting member 120 includes a plurality of adjusting plates 121, which can guide the airflow. Different rotation angles of the adjusting plates 121 relative to the bracket 110 can make the air duct adjusting member 120 have different states, so that the air duct adjusting member 120 can have different guiding effects on the airflow, and adjust the air outlet range and wind feeling of the airflow flowing out of the air duct adjusting member 120.

[0085] By linking the guide ring 130 with the adjustment plate 121, the rotation angle of the adjustment plate 121 relative to the bracket 110 can be adjusted when the guide ring 130 rotates relative to the bracket 110, so that the air duct adjustment member 120 can be switched between different states, thereby adjusting the air outlet range and wind feeling of the airflow flowing out of the air duct adjustment member 120.

[0086] In the related art, a guide mechanism for adjusting the direction of airflow is provided on the fan. However, the working state of the guide mechanism cannot be adjusted, resulting in a single blowing range and a single wind feeling of the fan, which cannot meet the user's usage needs and affects the user's usage experience.

[0087] The present application provides a rotating portion 1211 on the adjusting piece 121 so that the adjusting piece 121 can be rotatably connected to the bracket 110. By providing a guide ring 130, the guide ring 130 cooperates with the guide portion 1212 on the adjusting piece 121. When the guide ring 130 rotates relative to the bracket 110, the adjusting piece 121 is driven to rotate relative to the bracket 110 through the guide portion 1212. By rotating the adjusting piece 121 relative to the bracket 110 to adjust the rotation angle of the adjusting piece 121 relative to the bracket 110, the air duct adjusting member 120 can be switched in different states, thereby adjusting the air outlet range and air outlet feeling of the airflow flowing out of the air duct adjusting member 120 to meet the different usage requirements of users and improve the user experience.

[0088] According to the wind type control mechanism 100 of the present invention, a guide ring 130 that can rotate relative to the bracket 110 is provided, the guide part 1212 on the adjustment piece 121 cooperates with the driving ring 130, and the rotating part 1211 is rotatably connected to the bracket 110. When the guide ring 130 rotates relative to the bracket 110, it drives the adjustment piece 121 to rotate relative to the bracket 110. By rotating the adjustment piece 121 relative to the bracket 110 to adjust the rotation angle of the adjustment piece 121 relative to the bracket 110, the air duct adjustment member 120 can be switched in different states, thereby adjusting the air outlet range and air outlet feeling of the airflow flowing out of the air duct adjustment member 120 to meet the different usage requirements of users and improve the user experience.

[0089] It should be noted that the shape of the guiding ring 130 can be constructed as a polygonal shape or an annular shape. The specific shape of the guiding ring 130 is not limited herein, as long as it is ensured that the guiding ring 130 can rotate relative to the bracket 110.

[0090] In some embodiments of the present invention, the guiding portion 1212 is rotationally engaged with the rotating portion 1211. The guiding ring 130 is provided with a plurality of first guiding grooves 131. The guiding portions 1212 of the plurality of adjusting pieces 121 are arranged in one-to-one correspondence with the plurality of first guiding grooves 131, and each guiding portion 1212 is slidably engaged with the corresponding first guiding groove 131.

[0091] Specifically, the guiding portion 1212 of the adjusting piece 121 is slidably engaged with the first guiding groove 131 on the guiding ring 130. When the guiding ring 130 rotates relative to the bracket 110, the guiding ring 130 drives the first guiding groove 131 to rotate synchronously. The guiding portion 1212 slides relative to the first guiding groove 131, and at the same time, the first guiding groove 131 can drive the adjusting piece 121 to rotate relative to the bracket 110 through the guiding portion 1212.

[0092] For example, in combination with Figure 7 、 Figure 13 and Figure 14 , the first guiding groove 131 can be constructed as a groove structure that extends obliquely on the guiding ring 130, that is, one end of the first guiding groove 131 is arranged near the air outlet end of the guiding ring 130, and the other end of the first guiding groove 131 is arranged near the air inlet end of the guiding ring 130. When the guiding ring 130 rotates, due to the oblique extension of the first guiding groove 131, when the guiding portion 1212 slides relative to the first guiding groove 131, the first guiding groove 131 can drive the guiding portion 1212 to rotate. The guiding portion 1212 can drive the rotating portion 1211 and the adjusting piece 121 to rotate relative to the bracket 110, so as to realize the synchronous rotation of the guiding ring 130 driving the plurality of adjusting pieces 121. Of course, it can be understood that the arrangement manner of the first guiding groove 131 is not limited thereto, as long as it is ensured that when the guiding ring 130 rotates, the first guiding groove 131 can drive the adjusting piece 121 to rotate synchronously through the driving portion.

[0093] By rotating the adjusting piece 121 relative to the bracket 110 to adjust the rotation angle of the adjusting piece 121 relative to the bracket 110, the air duct adjusting member 120 can be switched between different states, thereby adjusting the air outlet range and the air outlet feeling of the air flow flowing out of the air duct adjusting member 120 to meet the different usage requirements of users and improve the user experience.

[0094] In combination with Figures 1 to 3, the air duct adjusting member 120 has a diffusing state and a wind-concentrating state. When it is necessary to adjust the air duct adjusting member 120 to the wind-concentrating state, the guiding ring 130 rotates and drives the adjusting piece 121 to rotate relative to the bracket 110 through the sliding fit of the first guiding groove 131 and the driving part. At this time, the air outlet end of the adjusting piece 121 rotates relative to the air inlet end in the direction close to the extension line of the central axis of the bracket 110, so that the area of the air outlet 122 of the air duct adjusting member 120 formed by surrounding of a plurality of adjusting pieces 121 is adjustable.

[0095] When it is necessary to adjust the air duct adjusting member 120 to the diffusing state, the guiding ring 130 rotates and drives the adjusting piece 121 to rotate relative to the bracket 110 through the sliding fit of the first guiding groove 131 and the driving part. At this time, the air outlet end of the adjusting piece 121 rotates relative to the air inlet end in the direction away from the extension line of the central axis of the bracket 110, so that the air outlet 122 of the air duct adjusting member 120 formed by surrounding of a plurality of adjusting pieces 121 expands in the direction away from the extension line of the central axis of the bracket 110, the area of the air outlet 122 of the air duct adjusting member 120 increases, the interference of the adjusting piece 121 on the circumferential component velocity of the air flow is small, and the air flow can still maintain a certain circumferential component velocity when discharging from the air duct adjusting member 120, so that the air outlet area is large and the air outlet is gentle, realizing the diffusing state of the air duct adjusting member 120.

[0096] It should be noted that the "air inlet end" refers to the end where the air flow flows into the component (such as the guiding ring 130, the bracket 110 or the air duct adjusting member 120, etc.) from the outside, and the "air outlet end" refers to the end where the air flow flows out from the inside of the component (such as the guiding ring 130, the bracket 110 or the air duct adjusting member 120, etc.). And the air inlet end of the air duct adjusting member 120 is the air inlet end of the adjusting piece 121. Similarly, the air outlet end of the air duct adjusting member 120 is the air outlet end of the adjusting piece 121.

[0097] Combined Figure 3 、 Figure 6 and Figure 8 , in some embodiments of the present invention, a plurality of rotation fitting parts 116 are arranged on the bracket 110. The plurality of rotation fitting parts 116 are arranged in one-to-one correspondence with a plurality of rotation parts 1211. The rotation parts 1211 are arranged at the air inlet end of the adjusting piece 121 and are embedded in the rotation fitting parts 116. The guiding part 1212 is located on the side of the rotation part 1211 close to the air outlet end of the adjusting piece 121 to prevent interference between the rotation part 1211 and the guiding part 1212. And the rotation part 1211 can be connected to the rotation fitting part 116 through a rotating shaft, so as to realize the rotatable connection between the rotation part 1211 and the bracket 110, which is beneficial to ensuring the connection reliability between the adjusting piece 121 and the bracket 110, and can ensure the rotation stability of the adjusting piece 121 when rotating relative to the bracket 110.

[0098] Optionally, the rotation fitting portion 116 can be configured as a groove structure, and the rotation portion 1211 can be configured as a convex structure, so as to facilitate the embedded fit between the rotation portion 1211 and the rotation fitting portion 116, and facilitate the positioning and installation of the adjusting piece 121 on the bracket 110, improving the assembly convenience of the adjusting piece 121.

[0099] Combined with Figures 13 to 18 , in some embodiments of the present invention, the bracket 110 is provided with a guiding channel 111, and the guiding portion 1212 passes through the guiding channel 111 and is in sliding fit with the first guiding groove 131.

[0100] Specifically, a plurality of guiding channels 111 are provided. The guiding channels 111 are adjacent to and oppositely arranged with the rotation fitting portion 116. The plurality of guiding channels 111 are arranged at the air outlet end of the bracket 110 and are sequentially spaced along the circumferential direction. A plurality of adjusting pieces 121 are arranged in one-to-one correspondence with the plurality of guiding channels 111. When the adjusting piece 121 is installed on the bracket 110 and the guiding portion 1212 is in sliding fit with the guiding ring 130, the end of the guiding portion 1212 facing away from the adjusting piece 121 passes through the guiding channel 111 and is in sliding fit with the first guiding groove 131. The guiding channel 111 can limit the guiding portion 1212 in the circumferential direction of the guiding portion 1212, preventing the guiding portion 1212 from shaking and affecting the driving effect of the guiding ring 130 on the adjusting piece 121. And when the structural strength of the guiding portion 1212 is small, the guiding channel 111 can prevent the guiding portion 1212 from deforming, ensuring the driving effect of the guiding ring 130 on the adjusting piece 121.

[0101] Among them, a plurality of convex structures arranged at intervals along the circumferential direction can be provided on the bracket 110. The convex structures bulge from the bracket 110 in the radial direction away from the bracket 110. A through hole is formed in the convex structure along the direction parallel to the central axis of the bracket 110 to form the guiding channel 111; the guiding channel 111 can also be formed by a ring structure provided on the bracket 110. The setting method of the guiding channel 111 is not specifically limited herein, as long as it is ensured that the guiding portion 1212 can pass through the guiding channel 111 and be in sliding fit with the first guiding groove 131.

[0102] Combined with Figure 7 and Figure 8 as well as Figures 13 to 15 , in some embodiments of the present invention, each adjusting piece 121 further includes a positioning rod 1213. One end of the positioning rod 1213 is connected to the guiding portion 1212, extends out of the first guiding groove 131 and is in sliding fit with the first guiding groove 131.

[0103] Specifically, combined with Figure 3 , Figure 7 and Figure 8, a plurality of extension plates 139 are arranged at intervals in the circumferential direction on the guide ring 130. The extension plates 139 extend from the guide ring 130 in the radial direction away from the guide ring 130. The first guide groove 131 is formed on the extension plate 139, and the first guide groove 131 extends obliquely on the extension plate 139, that is, one end of the first guide groove 131 is arranged closer to the central axis of the guide ring 130 in the radial direction relative to the other end, and the other end of the first guide groove 131 is arranged relatively farther away from the central axis of the guide ring 130. The arrangement modes of the plurality of first guide grooves 131 are the same.

[0104] Further, the positioning rod 1213 is connected to the side of the guiding portion 1212 away from the air outlet end of the adjusting piece 121, and the positioning rod 1213 is arranged at intervals from the adjusting piece 121 and the rotating portion 1211. The positioning rod 1213 extends from the guiding portion 1212 in the direction away from the air outlet end of the adjusting piece 121. The positioning rod 1213 can pass through the first guide groove 131 and be in sliding fit with the first guide groove 131. And because the positioning rod 1213 is connected to the guiding portion 1212, the guiding portion 1212 can be in sliding fit with the first guide groove 131.

[0105] Refer to Figure 13 , when the guide ring 130 rotates relative to the bracket 110, the first guide groove 131 rotates synchronously, and the positioning rod 1213 slides in the first guide groove 131. Because the first guide groove 131 is obliquely arranged, when the positioning rod 1213 slides in the first guide groove 131, the part of the positioning rod 1213 close to the first guide groove 131 can move in the radial direction towards or away from the central axis of the bracket 110.

[0106] Specifically, when the positioning rod 1213 moves from the end of the first guide groove 131 away from the central axis of the guide ring 130 towards the end close to the central axis of the guide ring 130, the end of the positioning rod 1213 away from the guiding portion 1212 moves in the radial direction towards the central axis of the guide ring 130, and the end of the positioning rod 1213 close to the guiding portion 1212 moves in the radial direction away from the central axis of the guide ring 130. The positioning rod 1213 drives the adjusting piece 121 to rotate through the guiding portion 1212, and the air outlet end of the adjusting piece 121 moves in the radial direction away from the central axis of the air duct adjusting member 120, so that the air outlet ends of the plurality of adjusting pieces 121 expand in the radial direction away from the central axis of the air duct adjusting member 120, and the area of the air outlet 122 of the air duct adjusting member 120 increases, realizing the air-diffusing state of the air duct adjusting member 120.

[0107] When the positioning rod 1213 moves from one end of the first guiding groove 131 close to the central axis of the guiding ring 130 towards the other end away from the central axis of the guiding ring 130, the end of the positioning rod 1213 away from the guiding part 1212 moves in the radial direction away from the central axis of the guiding ring 130, and the end of the positioning rod 1213 close to the guiding part 1212 moves in the radial direction towards the central axis of the guiding ring 130. The positioning rod 1213 drives the adjusting piece 121 to rotate through the guiding part 1212. The air outlet end of the adjusting piece 121 converges in the radial direction towards the central axis of the air duct adjusting member 120, and the area of the air outlet 122 of the air duct adjusting member 120 increases, realizing the air gathering state of the air duct adjusting member 120.

[0108] One end of the positioning rod 1213 extending out of the first guiding groove 131 is beneficial to preventing the positioning rod 1213 from disengaging from the first guiding groove 131 during driving, ensuring the cooperation reliability between the positioning rod 1213 and the first guiding groove 131. Of course, it can be understood that the above arrangement mode of the first guiding groove 131 and the cooperation mode between the positioning rod 1213 and the first guiding groove 131 are only one embodiment of the present invention, and cannot be understood as a limitation to this application. The arrangement mode of the first guiding groove 131 and the cooperation mode between the positioning rod 1213 and the first guiding groove 131 can be determined during actual production and processing, as long as the sliding cooperation between the positioning rod 1213 and the first guiding groove 131 is ensured.

[0109] Combined with Figure 3 、 Figure 7 、 Figure 8 and Figure 19 , in some embodiments of the present invention, the guiding ring 130 is further provided with an avoidance groove 133, and the avoidance groove 133 is adapted to avoid the end of the positioning rod 1213 away from the guiding part 1212.

[0110] Specifically, the length of the positioning rod 1213 is related to the rotation angle required by the adjusting piece 121. When the rotation angle of the adjusting piece 121 is large, the difference in the air outlet range and air outlet feeling of the air duct adjusting member 120 in the air dispersing state and the air gathering state is large, which is beneficial to meeting the use requirements of different users. And when the required rotation angle of the adjusting piece 121 is larger, the length of the positioning rod 1213 is longer. The specific length of the positioning rod 1213 can be determined according to the air outlet requirements of the air type control mechanism 100, and no specific limitation is made here.

[0111] Further, the avoidance grooves 133 are formed on the guiding ring 130, and a plurality of avoidance grooves 133 are provided. The plurality of avoidance grooves 133 are arranged at intervals in the circumferential direction. The avoidance grooves 133 are arranged adjacent to the extension plate 139. The avoidance grooves 133 are used to avoid the end of the positioning rod 1213 away from the guiding portion 1212, preventing the positioning rod 1213 from abutting against the outer wall surface of the guiding ring 130 and affecting the driving effect, which is beneficial to ensuring that the adjusting piece 121 has a sufficient rotation angle.

[0112] It should be noted that the cooperation mode between the guiding ring 130 and the air duct adjusting member 120 is not limited to this. For example, a protruding extension can be provided on the guiding ring 130, and a guiding groove can be provided on the guiding portion. The protruding extension extends into the guiding groove. As long as the rotation of the guiding ring 130 can drive the plurality of adjusting pieces 121 to rotate synchronously.

[0113] Combined with Figures 1 to 7 , in some embodiments of the present invention, the air pattern regulating mechanism 100 further includes a guide vane assembly 140 located at the air inlet end of the air duct adjusting member 120. The guide vane assembly 140 includes a plurality of first guide vanes 141. The plurality of first guide vanes 141 are rotatable relative to the bracket 110 and are arranged at intervals in the circumferential direction of the bracket 110.

[0114] Specifically, the guide vane assembly 140 is located at the air inlet end of the air duct adjusting member 120. The plurality of first guide vanes 141 are arranged at intervals in the circumferential direction of the bracket 110. A gap is formed between every two adjacent first guide vanes 141. After the air flow flows to the air pattern regulating mechanism 100, it successively flows through the guide vane assembly 140 and the air duct adjusting member 120. When the air flow flows through the guide vane assembly 140, it flows through the gap between the adjacent first guide vanes 141. And when the air flow flows into the gap between the adjacent first guide vanes 141, the first guide vanes 141 can guide the air flow to adjust the circumferential component velocity and the axial component velocity of the air flow.

[0115] Further, the plurality of first guide vanes 141 can be rotatable relative to the bracket 110 to facilitate adjusting the guiding effect of the guide vane assembly 140 on the air flow, thereby adjusting the air outlet intensity and the air outlet area of the air pattern regulating mechanism 100.

[0116] It should be noted that the "guide vane assembly 140 located at the air inlet end of the air duct adjusting member 120" only refers to the positional relationship between the air duct adjusting member 120 and the guide vane assembly 140 in the direction parallel to the rotation center axis of the guiding ring 130. The guide vane assembly 140 can be arranged inside the space formed by the air duct adjusting member 120 or outside the space formed by the air duct adjusting member 120.

[0117] Combined with Figures 3 to 7, in some embodiments of the present invention, a mounting seat 112 is provided in the middle of the bracket 110. Both ends of each first guide vane 141 are rotatably arranged on the mounting seat 112 and the bracket 110 through a rotating shaft 1413 respectively, and each first guide vane 141 is provided with a first matching portion 1411; the guiding ring 130 cooperates with the first matching portions 1411 of the plurality of first guide vanes 141 to drive the plurality of first guide vanes 141 to swing synchronously.

[0118] Specifically, an installation space 117 is formed inside the bracket 110. The mounting seat 112 is arranged inside the installation space 117, and the mounting seat 112 is connected to the bracket 110 through a connecting rib 1121. The mounting seat 112 and the bracket 110 jointly define an annular assembly space. A plurality of first holes 1122 arranged at intervals in the circumferential direction are provided on the mounting seat 112, and only a plurality of second holes 1101 arranged at intervals in the circumferential direction are provided on the bracket 110. A rotating shaft 1413 is provided on each first guide vane 141. One end of the first guide vane 141 is rotatably inserted into the first hole 1122 through the rotating shaft 1413, and the other end of the first guide vane 141 is rotatably inserted into the second hole 1101 through the rotating shaft 1413, so that the first guide vane 141 can rotate relative to the bracket 110 and the mounting seat 112, and the rotation axis of the first guide vane 141 is approximately tangent to the outer diameter of the mounting seat 112.

[0119] Furthermore, a first matching portion 1411 is provided at one end of the first guide vane 141 rotatably connected to the bracket 110. The first matching portion 1411 is adjacent to and spaced from the rotating shaft 1413. The guiding ring 130 can cooperate with the first matching portions 141 of the plurality of first guide vanes 141, so that when the guiding ring 130 rotates, it can drive the plurality of first guide vanes 141 to swing around the rotating shaft 1413 thereon, so that the plurality of first guide vanes 141 can rotate relative to the bracket 110.

[0120] Combined with Figures 3 to 7 , in some embodiments of the present invention, the guiding ring 130 is provided with a plurality of second guiding grooves 134. The plurality of first matching portions 1411 and the plurality of second guiding grooves 134 are in one-to-one correspondence and cooperation. The first matching portion 1411 of each first guide vane 141 is in sliding cooperation with the corresponding second guiding groove 134.

[0121] Specifically, a plurality of second guiding grooves 134 arranged at intervals in the circumferential direction are provided on the guiding ring 130. The plurality of second guiding grooves 134 are arranged in one-to-one correspondence with the plurality of first matching portions 1411, and each first matching portion 1411 can be in sliding cooperation with the corresponding second guiding groove 134. When the first matching portion 1411 slides in the second guiding groove 134, it can drive the first guide vane 141 to rotate around the central axis of the rotating shaft 1413.

[0122] Combined with Figure 4 andFigure 5 In some embodiments of the present invention, a reinforcing protrusion 1412 is provided at one end of the first guide vane 141. The thickness of the reinforcing protrusion 1412 is greater than that of the guide vane. The rotating shaft 1413 and the first engaging portion 1411 at one end are respectively provided on the reinforcing protrusion 1412.

[0123] Specifically, a reinforcing protrusion 1412 is provided at the end of the first guide vane 141 close to the bracket 110. The reinforcing protrusion 1412 can increase the cross-sectional area of the end of the first guide vane 141. The first engaging portion 1411 of the first guide vane 141 and the rotating shaft 1413 at the end close to the bracket 110 can be respectively provided on the reinforcing protrusion 1412 to facilitate the arrangement of the first engaging portion 1411 and the rotating shaft 1413.

[0124] Furthermore, the reinforcing protrusion 1412 can be in abutting cooperation with the bracket 110, which is beneficial to improving the stability of the first guide vane 141 during rotation. And since the thickness of the reinforcing protrusion 1412 is greater than that of the guide vane, the strength of the reinforcing protrusion 1412 is greater than that of the guide vane, so as to effectively reduce the risk of the first guide vane 141 breaking or being damaged due to the abutment between the first guide vane 141 and the bracket 110.

[0125] Combined Figure 3 and Figure 20 In some embodiments of the present invention, the guiding ring 130 is sleeved outside the bracket 110. The bracket 110 is provided with a plurality of first guiding holes 113. A plurality of second guiding grooves 134 are arranged in one-to-one correspondence with the plurality of first guiding holes 113. The first engaging portion 1411 of each first guide vane 141 passes through the first guiding hole 113 and is in sliding cooperation with the corresponding second guiding groove 134.

[0126] Specifically, the guiding ring 130 is sleeved outside the bracket 110 and the guiding ring 130 can rotate relative to the bracket 110. A plurality of first guiding holes 113 are arranged at intervals in the circumferential direction on the bracket 110. The first guiding holes 113 are adjacent to the second holes 1101. At the same time, the plurality of first guiding holes 113 and the plurality of second guiding grooves 134 are arranged opposite to each other in the radial direction. The first engaging portion 1411 passes through the first guiding hole 113 and is in sliding cooperation with the corresponding second guiding groove.

[0127] Furthermore, when the guiding ring 130 rotates relative to the bracket 110, the second guiding groove 134 drives the first engaging portion 1411 to slide relatively in the second guiding groove 134. At the same time, the groove wall of the second guiding groove 134 can drive the first engaging portion 1411 to slide in the first guiding hole 113. The first engaging portion 1411 drives the first guide vane 141 to rotate around the central axis of the rotating shaft 1413, thereby adjusting the guiding effect of the plurality of first guide vanes 141 on the airflow.

[0128] Among them, the first guiding hole 113 can be configured as an arc-shaped hole structure centered on the second hole 1101. The first guiding hole 113 is used to limit the first guide vane 141 to rotate within a designed range.

[0129] Combined Figure 1 with Figure 2 , in some embodiments of the present invention, the first guide vane 141 can rotate to switch between a first state and a second state. The guiding ring 130 has a rotational central axis; the deflection angle of the first guide vane 141 relative to the rotational central axis in the first state is greater than that in the second state, so that the air flow is in a divergent state after flowing through the first guide vane 141 in the first state.

[0130] It should be noted that the rotational central axis of the guiding ring 130 is arranged parallel or collinear with the rotational central axis of the driving fan 300.

[0131] Specifically, when the first guide vane 141 is in the second state, the first guide vane 141 can be parallel to the rotational central axis of the guiding ring 130 or the first guide vane 141 can be slightly deviated from the rotational central axis of the guiding ring. At this time, the extending direction of the first guide vane 141 is different from the flowing direction of the air flow, and the air flow will impact on the first guide vane 141, and the first guide vane 141 can guide the air flow, so that the circumferential component velocity of the air flow is converted into an axial component velocity, and the air flow converges towards the direction close to the rotational central axis of the guiding ring.

[0132] When the first guide vane 141 is in the first state, the first guide vane 141 deflects, and the included angle formed between the first guide vane 141 and the first central axis increases. At this time, the extending direction of the first guide vane 141 is basically the same as the flowing direction of the air flow. When the air flow flows through the first guide vane 141, it can effectively maintain its original flowing direction, so that the air flow as a whole presents a conical shape after flowing out, that is, the air flow deflects in the direction deviating from the first central axis, and the air flow diverges.

[0133] Combined Figure 1 with Figure 2 , in some embodiments of the present invention, at the air outlet end of the first guide vane 141 in the first state, it extends outward towards the inner peripheral wall of the air duct adjusting member 120 relative to the air inlet end of the first guide vane 141, and at the air outlet end of the first guide vane 141 in the second state, it guides the air flow towards the direction deviating from the inner peripheral wall of the air duct adjusting member 120.

[0134] Specifically, in the first state, in the direction of the central axis extension of the bracket 110, the first guide vane 141 is arranged obliquely. The air inlet end of the first guide vane 141 is relatively close to the central axis of the bracket 110, and the air outlet end of the first guide vane 141 is relatively close to the inner peripheral wall of the air duct adjusting member 120. At this time, the extension direction of the first guide vane 141 is basically the same as the flow direction of the air flow. The adjustment effect of the first guide vane 141 on the air flow is small, and the original circumferential component velocity of the air flow can be effectively maintained, so that the air flow can be conical after flowing out, thus ensuring the divergent state when the air flow flows out.

[0135] It should be noted that the air flow flowing through the air flow type control mechanism 100 is spiral, and it has a circumferential component velocity and an axial component velocity.

[0136] When it is necessary to switch the first guide vane 141 from the first state to the second state, the guiding ring 130 rotates and drives the second guiding groove 134 to rotate synchronously. The second guiding groove 134 drives the first engaging portion 1411 to slide in the first guiding hole 113. The first engaging portion 1411 drives the first guide vane 141 to rotate around the central axis of the rotating shaft 1413. The air outlet end of the first guide vane 141 deflects in a direction away from the inner peripheral wall of the air duct adjusting member 120. The first guide vane 141 can be perpendicular to the air outlet surface. At this time, the extension direction of the first guide vane 141 is different from the flow direction of the air flow. After the air flow impacts the first guide vane 141, the first guide vane 141 can guide the air flow, so that the circumferential component velocity of the air flow is converted into an axial component velocity. The air flow is cylindrical after flowing out of the air flow type control mechanism 100. The flow velocity of the air flow is large and the flow range is small, so as to adjust the air flow to a converging state. At this time, the air outlet intensity is large, thereby realizing the switching of the first guide vane 141 between the first state and the second state.

[0137] It should be noted that the "air outlet surface" refers to the cross-section where the air flow flows out of the bracket 110, and the air outlet surface is perpendicular to the central axis of the bracket 110; in addition, the first guide vane 141 can be perpendicular to the air outlet surface; there can also be a certain deviation between the angle between the first guide vane 141 and the air outlet surface and just being perpendicular, so as to reduce the processing accuracy requirements of the air flow type control mechanism 100. The specific angle setting can be determined according to the actual air outlet requirements and will not be specifically limited here as long as the adjustment effect of the first guide vane 141 on the air flow is ensured.

[0138] It can be understood that in combination with Figure 9 and Figure 10, the movement locus of the first engaging portion 1411 is: an arc movement with the central axis of the rotating shaft 1413 as the rotation center and the distance between the first engaging portion 1411 and the rotating shaft 1413 as the radius. Therefore, the first guiding hole 113 is configured as a circular arc around the second hole 1101 to adapt to the movement locus of the first engaging portion 1411, and the first guiding hole 113 can limit the movement range of the first engaging portion 1411, thereby limiting the rotation angle of the first guide vane 141. By designing the size of the first guiding hole 113 to ensure that the first engaging portion 1411 can move within the designed range, it is ensured that the first guide vane 141 can rotate within the designed range. Specifically, the size of the first guiding hole 113 can be designed according to the actual rotation range requirement of the first guide vane 141, and no specific limitation is made here.

[0139] The second guiding groove 134 has a first extreme position P and a second extreme position Q. The first extreme position P can be understood as the position of the central axis of the first engaging portion 1411 when it is located at one end of the second guiding groove 134, and the second extreme position Q can be understood as the position of the central axis of the first engaging portion 1411 when it is located at the other end of the second guiding groove 134. The length dimension of the first extreme position P and the second extreme position Q in the air outlet direction is the movement distance of the first engaging portion 1411 in the air outlet direction when it moves from the first extreme position P to the second extreme position Q (or from the second extreme position Q to the first extreme position P).

[0140] The arc length of the first extreme position P and the second extreme position Q of the second guiding groove 134 in the circumferential direction is related to the maximum angle of the guiding ring 130 running. The arc length of the first extreme position P and the second extreme position Q of the second guiding groove 134 in the circumferential direction is greater than or equal to the running angle of the guiding ring 130 multiplied by the radius of the guiding ring 130. Specifically, the shape of the second guiding groove 134 and the running angle of the guiding ring 130 can be designed according to the actual rotation range requirement of the first guide vane 141, and no specific limitation is made here.

[0141] The following combines Figures 1 to 10 Briefly describe the process of the air pattern regulating mechanism 100 adjusting the working states of the air duct adjusting member 120 and the guide vane assembly 140. Among them, taking the example that the first engaging portion 1411 is located at the second extreme position Q when the first guide vane 141 is in the first state and the first engaging portion 1411 is located at the first extreme position P when the first guide vane 141 is in the second state for illustration.

[0142] When it is necessary to adjust the air pattern control mechanism 100 from the air-diffusing mode to the air-concentrating mode, the guiding ring 130 rotates relative to the bracket 110, and the positioning rod 1213 moves from one end of the first guiding groove 131 close to the central axis of the guiding ring 130 to the other end away from the central axis of the guiding ring 130. The end of the positioning rod 1213 away from the guiding part 1212 moves in the radial direction away from the central axis of the guiding ring 130, and the end of the positioning rod 1213 close to the guiding part 1212 moves in the radial direction towards the central axis of the guiding ring 130. The positioning rod 1213 drives the adjusting piece 121 to rotate through the guiding part 1212, and the air outlet end of the adjusting piece 121 converges in the radial direction towards the central axis of the air duct adjusting part 120, and the area of the air outlet 122 of the air duct adjusting part 120 increases, realizing the air-concentrating state of the air duct adjusting part 120.

[0143] At the same time, the guiding ring 130 drives the second guiding groove 134 to rotate synchronously. The first engaging part 1411 slides in the second guiding groove 134 towards the first extreme position P. At the same time, due to the rotation of the guiding ring 130 relative to the bracket 110, the area of the second guiding groove 134 facing the first guiding hole 113 gradually decreases. When the first engaging part 1411 slides in the second guiding groove 134 to the first extreme position P, the first engaging part 1411 is at the opposite end in the first guiding hole 113. For example, when the first extreme position P is the left end of the second guiding groove 134, the first engaging part 1411 is at the right end of the first guiding hole 113; when the first extreme position P is the right end of the second guiding groove 134, the first engaging part 1411 is at the left end of the first guiding hole 113.

[0144] It should be noted that "left" and "right" respectively refer to the left and right directions in the perspective of the front view of the air pattern control mechanism 100.

[0145] The first engaging part 1411 drives the first guide vane 141 to rotate around the central axis of the rotating shaft 1413. The air outlet end of the first guide vane 141 deflects towards the direction deviating from the inner peripheral wall of the air duct adjusting part 120. The first guide vane 141 can be perpendicular to the air outlet surface. At this time, the extending direction of the first guide vane 141 is different from the flowing direction of the air flow. After the air flow impacts on the first guide vane 141, the first guide vane 141 can guide the air flow, so that the circumferential component velocity of the air flow is converted into the axial component velocity. The air flow flows out of the air pattern control mechanism 100 in a cylindrical shape, and the flow velocity of the air flow is large and the flow range is small, thereby adjusting the air flow to the converging state.

[0146] At this time, the air duct adjusting part 120 is in the air-concentrating state, and at the same time, the first guide vane 141 is in the second state. The air flow flows through the first guide vane 141 and then further flows into the air duct adjusting part 120. The air duct adjusting part 120 further arranges the air flow to improve the air-concentrating effect of the air pattern control mechanism 100.

[0147] When it is necessary to adjust the wind type regulating mechanism 100 from the wind-gathering state to the wind-dispersing state, the guiding ring 130 can be driven in the reverse direction. The moving directions of components such as the positioning rod 1213 and the first engaging portion 1411 are opposite to the above-mentioned moving directions, so that the area of the air outlet 122 of the air duct adjusting member 120 increases. At the same time, the air outlet end of the first guide vane 141 deflects towards the inner peripheral wall of the air duct adjusting member 120, and the air flow is in a divergent state when flowing out of the wind type regulating mechanism 100.

[0148] It should be noted that when the guiding ring 130 rotates to the maximum angle, the working state adjustment of the wind type regulating mechanism 100 is completed.

[0149] Combined with Figures 11 to 14 , in some embodiments of the present invention, a plurality of first guide vanes 141 are provided on the guiding ring 130 to rotate synchronously with the guiding ring 130.

[0150] Specifically, a support seat 137 can be provided inside the guiding ring 130. The support seat 137 and the guiding ring 130 jointly define an annular arrangement space. A plurality of first guide vanes 141 are arranged in the annular arrangement space and are respectively connected to the guiding ring 130 and the support seat 137, so as to facilitate the assembly of the first guide vanes 141. And a plurality of first guide vanes 141 are connected to the guiding ring 130 so that the guiding ring 130 can drive a plurality of first guide vanes 141 to rotate synchronously.

[0151] Furthermore, a first gap is formed between every two adjacent first guide vanes 141. When the air flow passes through the first gap, the first guide vanes 141 can guide the air flow.

[0152] Combined with Figures 11 to 18 , in some embodiments of the present invention, an installation seat 112 is provided in the middle of the bracket 110; the guide vane assembly 140 further includes a plurality of second guide vanes 142. The plurality of second guide vanes 142 are arranged at intervals along the circumferential direction of the bracket 110. Both ends of each second guide vane 142 are respectively connected to the bracket 110 and the installation seat 112; the guiding ring 130 rotates to enable the guide vane assembly 140 to switch between a first state and a second state. In the first state, the plurality of first guide vanes 141 and the plurality of second guide vanes 142 are arranged in a one-to-one alignment in the front-rear direction. In the second state, the plurality of first guide vanes 141 and the plurality of second guide vanes 142 are arranged in a circumferential dislocation.

[0153] Specifically, combined with Figures 16 to 18, an installation space 117 is formed inside the bracket 110. The mounting base 112 is arranged inside the installation space 117. The mounting base 112 and the bracket 110 jointly define an annular assembly space. A plurality of second guide vanes 142 are arranged inside the annular assembly space, and the plurality of second guide vanes 142 are arranged at intervals along the circumferential direction of the bracket 110. A second gap is formed between every two adjacent second guide vanes 142. When the air flow enters the second gap, the second guide vanes 142 can guide the air flow. Both ends of each second guide vane 142 are fixedly connected to the mounting base 112 and the bracket 110 respectively to ensure the assembly reliability of the second guide vanes 142.

[0154] Further, the guiding ring 130 can be arranged opposite to the bracket 110 in the axial direction. The guiding ring 130 can rotate relative to the bracket 110, and the guiding ring 130 drives the first guide vanes 141 to rotate synchronously, so that the guide vane assembly 140 can be switched between the first state and the second state.

[0155] Among them, in combination with Figures 12 to 14 , when the guide vane assembly 140 is in the second state, in the direction of the extension of the central axis of the bracket 110, a plurality of first guide vanes 141 and a plurality of second guide vanes 142 are arranged in one-to-one correspondence. At this time, the first gap is opposite to the second gap. Taking the case where the air flow preferentially enters the first gap as an example, after the air flow enters the first gap and the first guide vanes 141 guide the air flow, the air flow continues to flow into the second gap, so that the second guide vanes 142 further guide the air flow. The circumferential component velocity of the air flow is converted into the circumferential component velocity, so that the air flow can be concentrated towards the extension line of the central axis of the bracket 110. The first gap and the second gap form a continuous flow space. The first guide vanes 141 and the second guide vanes 142 can continuously guide the air flow to continuously adjust the air flow, improve the rectification effect of the guide vane assembly 140 on the air flow, improve the effect of converting the circumferential component velocity of the air flow into the axial component velocity, reduce the flow area of the air flow in the radial direction when the air flow flows out of the guide vane assembly 140, so that the axial velocity of the air flow when it flows out is large, thereby improving the air outlet intensity.

[0156] Refer to Figure 11, when the guide vane assembly 140 is in the first state, in the direction of the central axis extension of the support 110, the orthographic projection of each first guide vane 141 is located between the orthographic projections of every two adjacent second guide vanes 142. That is, the multiple first guide vanes 141 and the multiple second guide vanes 142 are arranged in a circumferential dislocation, the first gap and the second gap are arranged in a dislocation. The first guide vane 141 and the second guide vane 142 cannot continuously guide the air flow. Compared with the second state, when the air flow flows into the first gap, the guiding time of the first guide vane 141 for the air flow is short. Similarly, when the air flow flows into the second gap, the guiding time of the second guide vane 142 for the air flow is short. The rectification effect of the guide vane assembly 140 on the air flow is reduced as a whole. When the air flow passes through the guide vane assembly 140, the circumferential component velocity of the air flow can be maintained, so that the air flow is in a conical shape when flowing out of the guide vane assembly 140, ensuring the divergent state when the air flow flows out.

[0157] It should be noted that the dimension of the first gap in the direction parallel to the central axis of the support 110 is the length dimension of the first gap, and the dimension of the second gap in the direction parallel to the central axis of the support 110 is the length dimension of the second gap.

[0158] Combined with Figures 11 to 14 , in some embodiments of the present invention, in the front-back direction, the support 110 is located on the front side of the guiding ring 130.

[0159] It should be noted that the "front-back direction" refers to the extension direction of the central axis of the support 110, the "front side" refers to the air outlet end of components such as the support 110 or the guiding ring 130, and the "rear side" refers to the air inlet end of components such as the support 110 or the guiding ring 130.

[0160] Specifically, the guiding ring 130 and the support 110 are arranged opposite to each other in the circumferential direction. The guiding ring 130 is located at the air inlet end of the support 110, and the air duct adjusting member 120 is located at the air outlet end of the support 110, so that the guiding ring 130 and the air duct adjusting member 120 are arranged at an interval, and the guiding ring 130 and the air duct adjusting member 120 can avoid each other to prevent the movement of the guiding ring 130 and the air duct adjusting member 120 from interfering with each other.

[0161] Combined with Figures 13 to 15 , in some embodiments of the present invention, the outer peripheral wall of the guiding ring 130 is provided with a plurality of outwardly protruding guiding protrusions 136, and each guiding protrusion 136 is provided with a first guiding groove 131.

[0162] Specifically, the outer peripheral wall of the guiding ring 130 is provided with a plurality of guiding protrusions 136 protruding in the radial direction away from the outer peripheral wall of the guiding ring 130. The plurality of guiding protrusions 136 are evenly arranged at intervals in the circumferential direction of the guiding ring 130, and the plurality of guiding protrusions 136 are arranged in one-to-one correspondence with the plurality of adjusting pieces 121.

[0163] Further, each guiding protrusion 136 is provided with a first guiding groove 131 extending obliquely, that is, in a direction parallel to the central axis of the guiding ring 130, one end of the first guiding groove 131 is arranged near the air outlet end of the guiding ring 130, the other end of the first guiding groove 131 is arranged near the air inlet end of the guiding ring 130, and the first guiding groove 131 is open on the side deviating from the guiding ring 130 in the radial direction. The positioning rod 1213 can be inserted into the first guiding groove 131. When the guiding ring 130 rotates relative to the bracket 110, the first guide vane 141 and the second guide vane 142 are arranged opposite to or offset from each other. At the same time, the positioning rod 1213 slides in the first guiding groove 131. Since the first guiding groove 131 extends obliquely, the positioning rod 1213 moves along the axial direction parallel to the guiding ring 130 at the same time. The guiding part 1212 is rotatably connected to the rotating part 1211, and the rotation axis between the guiding part 1212 and the rotating part 1211 is parallel to the rotation axis of the adjusting piece 121 relative to the bracket 110. The positioning rod 1213 drives the guiding part 1212 to rotate relative to the rotating part 1211, and at the same time, the positioning rod 1213 drives the rotating part 1211 to rotate relative to the bracket 110, so that the positioning rod 1213 and the guiding part 1212 can move along the axial direction.

[0164] Further, the rotating part 1211 is fixedly connected to the adjusting piece 121. Therefore, the rotating part 1211 can drive the adjusting piece 121 to rotate relative to the bracket 110, so as to facilitate adjusting the opening area of the air duct adjusting member 120, thereby adjusting the working mode of the air duct adjusting member 120.

[0165] It should be noted that when the guiding ring 130 rotates to make the first guide vane 141 and the second guide vane 142 offset from each other, the first guiding groove 131 drives the positioning rod 1213 to move away from the air duct adjusting member 120 in a direction parallel to the central axis of the guiding ring 130. The positioning rod 1213 drives the guiding part 1212 to move away from the air duct adjusting member 120. The guiding part 1212 drives the adjusting piece 121 to rotate through the rotating part 1211, and makes the air outlet end of the adjusting piece 121 move away from the central axis of the air duct adjusting member 120, so that the air outlet 122 of the air duct adjusting member 120 expands, and the area of the air outlet 122 of the air duct adjusting member 120 increases. At this time, the guide vane assembly 140 is in the first state, the air duct adjusting member 120 is in the air-diffusing state, and the air pattern control mechanism 100 is in the air-diffusing mode.

[0166] When the guiding ring 130 rotates such that the first guide vane 141 faces the second guide vane 142, the first guiding groove 131 drives the positioning rod 1213 to move in a direction parallel to the central axis of the guiding ring 130 and towards the air duct adjusting member 120. The positioning rod 1213 drives the guiding portion 1212 to move towards the air duct adjusting member 120. The guiding portion 1212 drives the adjusting piece 121 to rotate through the rotating portion 1211, and causes the air outlet end of the adjusting piece 121 to move towards the central axis of the air duct adjusting member 120, thereby causing the air outlet 122 of the air duct adjusting member 120 to contract, reducing the area of the air outlet 122 of the air duct adjusting member 120. At this time, the guide vane assembly 140 is in the second state, the air duct adjusting member 120 is in the air concentrating state, and the air type regulating mechanism 100 is in the air concentrating mode.

[0167] Combined Figures 17 to 20 , in some embodiments of the present invention, the air type regulating mechanism 100 further includes an electric driving device 150, and the electric driving device 150 is connected to the guiding ring 130 to drive the guiding ring 130 to reciprocally rotate.

[0168] Specifically, the output end of the electric driving device 150 is connected to the guiding ring 130 such that when the electric driving device 150 outputs power, it can drive the guiding ring 130 to reciprocally rotate, so that the air type regulating mechanism 100 can switch between the air dispersing mode and the air concentrating mode, and manual operation is not required, effectively improving the adjustment convenience of the air type regulating mechanism 100.

[0169] In some embodiments of the present invention, the electric driving device 150 includes a motor 151 and a connecting rod assembly 152. The connecting rod assembly 152 and the guiding ring 130 cooperate to define a crank-rocker mechanism, and the motor 151 is connected to the crank in the crank-rocker mechanism.

[0170] Specifically, a connecting rod assembly 152 is provided at the output end of the motor 151, and a connecting portion 138 is provided on the guiding ring 130. The connecting rod assembly 152 is connected to the connecting portion 138. At this time, the connecting rod assembly 152 cooperates with the guiding ring 130 to define a crank-rocker mechanism. The guiding ring 130 serves as the rocker in the crank-rocker mechanism, and the connecting rod assembly 152 serves as the crank in the crank-rocker mechanism. When the motor 151 outputs power, the motor 151 can drive the crank to perform a small-distance reciprocating rotation (i.e., the motor 151 drives the connecting rod assembly 152 to perform a small-distance reciprocating rotation). The crank drives the rocker to rotate for a small-distance reciprocating rotation, that is, the connecting rod assembly 152 drives the guiding ring 130 to perform a reciprocating rotation at a fixed angle. When the guiding ring 130 performs a reciprocating rotation, the guiding ring 130 can drive the first guide vane 141 and the adjusting piece 121 to perform a reciprocating rotation, so that the guide vane assembly 140 can be switched between a first state and a second state. At the same time, the air duct adjusting member 120 can be switched between a diffusing state and a concentrating state, thereby realizing the switching of the air pattern control mechanism 100 between a diffusing mode and a concentrating mode. Among them, the motor 151 can be configured as a tilting motor.

[0171] When the guiding ring 130 rotates to one side limit angle, the working state adjustment of the air pattern control mechanism 100 is completed, and the air pattern control mechanism 100 is in a diffusing mode or a concentrating mode.

[0172] Combined with Figure 14 、 Figure 17 and Figure 18 In some embodiments of the present invention, a receiving cavity 114 for accommodating the motor 151 and the connecting rod assembly 152 is provided in the bracket 110, and the connecting rod assembly 152 is connected to the middle of the guiding ring 130.

[0173] Specifically, a receiving cavity 114 is formed in the mounting seat 112, and a motor support 1123 is provided on the inner wall of the mounting seat 112. The motor 151 is mounted on the motor support 1123, so that the motor support 1123 and the connecting rod assembly 152 can be mounted in the receiving cavity 114.

[0174] Further, the support seat 137 is opposite to the mounting seat 112, and a connecting portion 138 is provided on the support seat 137. The connecting portion 138 can be configured as a connecting rod mounting post. A part of the connecting rod assembly 152 extends out of the receiving cavity 114 and is connected to the connecting portion 138. And since the support seat 137 is fixedly connected to the guiding ring 130, when the motor 151 outputs power, the guiding ring 130 can be driven to rotate through the connecting rod assembly 152 and the connecting portion 138.

[0175] In addition, an avoidance portion 1371 is provided on the support base 137. The avoidance portion 1371 can be configured as an arc-shaped groove structure. The avoidance portion 1371 can avoid the part of the connecting rod assembly 152 extending out of the accommodation cavity 114, so as to facilitate the connection between the connecting rod assembly 152 and the connecting portion 138, and improve the assembly convenience of the connecting rod assembly 152 and the connecting portion 138.

[0176] Combined with Figure 19 and Figure 20 , in some other embodiments of the present invention, the electric drive device 150 can be arranged outside the bracket 110, the connecting portion 138 can be arranged on the guide ring 130, and the connecting rod assembly 152 is connected to the connecting portion 138 so that the motor 151 can drive the guide ring 130 to rotate.

[0177] As Figure 20 shown, in some embodiments of the present invention, the electric drive device 150 further includes a motor 151, a drive gear 153 and a meshing tooth portion 154. The motor 151 is connected to the drive gear 153 to drive the drive gear 153 to rotate. The meshing tooth portion 154 is arranged on the guide ring 130, and the drive gear 153 meshes with the meshing tooth portion 154 to drive the guide ring 130 to rotate reciprocally.

[0178] Specifically, a drive gear 153 is arranged at the output end of the motor 151, and a meshing tooth portion 154 is arranged on the guide ring 130. The meshing tooth portion 154 is used for meshing and cooperating with the drive gear 153. When the motor 151 outputs power, the drive gear 153 rotates and drives the meshing tooth portion 154 meshing with it to rotate. The meshing tooth portion 154 drives the guide ring 130 to rotate, so that the electric drive device 150 can drive the guide ring 130 to rotate reciprocally, and the guide ring 130 can drive the first guide vane 141 and the adjusting piece 121 to rotate reciprocally. The guide vane assembly 140 can be switched between a first state and a second state, and at the same time, the air duct adjusting member 120 can be switched between a diffusing state and a concentrating state, so as to realize the working mode of the air type regulating mechanism 100.

[0179] Among them, the motor 151 can be configured as a stepper motor, and the stepper motor rotates reciprocally to drive the guide ring 130 to rotate reciprocally.

[0180] Combined with Figure 27 and Figure 28 , according to the fan 1000 of the present invention, it includes: an air type regulating mechanism 100, which is the above-mentioned air type regulating mechanism 100; a driving fan 300, which is used to send air towards the air type regulating mechanism 100, for example, arranged on the air inlet side of the air duct adjusting member 120.

[0181] It should be noted that the side of the bracket 110 away from the air duct adjusting member 120 in the axial direction is defined as the air inlet side of the bracket 110.

[0182] Specifically, the driving fan 300 drives air to form an air flow, and the air flow sequentially passes through the guide vane assembly 140 and the air duct adjusting member 120. The guide vane assembly 140 and the air duct adjusting member 120 guide the air flow, and the air flow flows out of the fan 1000 through the air outlet area 220 after flowing out of the air duct adjusting member 120, realizing the air supply of the fan 1000.

[0183] Since the fan 1000 is provided with the above-mentioned air pattern control mechanism 100, by providing a guiding ring 130 that can rotate relative to the bracket 110, the guiding portion 1212 on the adjusting piece 121 cooperates with the driving ring 130, and the rotating portion 1211 is rotatably connected to the bracket 110. When the guiding ring 130 rotates relative to the bracket 110, it drives the adjusting piece 121 to rotate relative to the bracket 110. By rotating the adjusting piece 121 relative to the bracket 110 to adjust the rotation angle of the adjusting piece 121 relative to the bracket 110, the air duct adjusting member 120 can be switched between different states, thereby adjusting the air outlet range and the air outlet feeling of the air flow flowing out of the air duct adjusting member 120 to meet different usage requirements of users and improve the user experience. At the same time, the structure of the guiding ring 130 for adjusting the air pattern control mechanism 100 in this application is simple, which is beneficial to reducing the production cost of the air pattern control mechanism 100.

[0184] Combined Figure 27 and Figure 28 , in some embodiments of the present invention, the fan 1000 is provided with a housing 200, and the housing 200 is provided with an air inlet area 210 and an air outlet area 220. The air pattern control mechanism 100 and the driving fan 300 can be arranged inside the housing.

[0185] Specifically, the housing 200 is constructed as a cylindrical structure with a cavity. The housing 200 can be used as an installation carrier for the driving fan 300 and the air pattern control mechanism 100. The driving fan 300 and the air pattern control mechanism 100 can be installed inside the housing 200, and the housing 200 can play a role in protecting the driving fan 300 and the air pattern control mechanism 100, preventing the fan 1000 from being damaged due to external debris entering the driving fan 300 or the air pattern control mechanism 100.

[0186] Furthermore, an air inlet area 210 is formed at the rear side of the housing 200, and external air enters the housing 200 through the air inlet area 210. An air outlet area 220 is formed at the front side of the housing 200. The air outlet area 220 can be constructed as an opening formed at the front side of the housing 200. The driving fan 300 and the air pattern control mechanism 100 can be installed inside the housing 200 through the air outlet area 220, facilitating the assembly of the fan 1000.

[0187] Optionally, the driving fan 300 may be disposed outside the housing 200 . The specific arrangement of the driving fan 300 may be determined according to actual installation requirements of the fan 1000 , and is not specifically limited herein.

[0188] Combination Figures 24 to 26 In some embodiments of the present invention, the wind type control mechanism 100 is the above-mentioned wind type control mechanism 100, the outer shell 200 is provided with a slide groove 230, and the guide ring 130 is provided with a toggle portion 135, the toggle portion 135 is passed through the slide groove 230 to extend out of the outer shell 200, and the toggle portion 135 is toggled to drive the guide ring 130 to rotate.

[0189] Specifically, the toggle portion 135 is disposed on the guide ring 130 and extends in a radial direction away from the central axis of the guide ring 130. A slide groove 230 is disposed on the outer shell 200. The slide groove 230 can be constructed as an oblong hole extending in a circumferential direction of the outer shell 200. The toggle portion 135 is passed through the slide groove 230 and extends out of the outer shell 200. The user can drive the toggle portion 135 to slide in the slide groove 230, and the toggle portion 135 drives the guide ring 130 to rotate, thereby realizing manually driving the guide ring 130 to rotate, and further realizing the working mode of manually adjusting the wind type control mechanism 100.

[0190] Combination Figure 3 , Figure 6 , Figure 13 , Figure 16 , Figures 21 to 23 as well as Figure 25 In some embodiments of the present invention, a mounting portion 240 is provided in the housing 200, and a mounting matching portion 115 is provided on the bracket 110, and the mounting matching portion 115 is used to connect with the mounting portion 240 so that the wind type control mechanism 100 is installed in the housing 200.

[0191] Specifically, combined Figure 3 , Figure 6 , Figure 13 , Figure 16 as well as Figure 25 The mounting portion 240 can be constructed as a plate structure. Similarly, the mounting matching portion 115 can be constructed as a plate structure, and a plurality of mounting portions 240 and mounting matching portions 115 can be provided. When the wind type control mechanism 100 is arranged in the shell 200, a plurality of mounting portions 240 and a plurality of mounting matching portions 115 are arranged in a one-to-one correspondence. A threaded connector can be passed through the mounting portion 240 and the mounting matching portion 115 to fix the mounting portion 240 and the mounting matching portion 115 together, so that the wind type control mechanism 100 can be installed in the shell 200, and this assembly method can realize the detachable connection between the wind type control mechanism 100 and the shell 200, so as to facilitate the disassembly or replacement of the wind type control mechanism 100.

[0192] Optionally, refer toFigure 22 The installation part 240 can be configured as an internal thread, and the installation mating part 115 can be configured as an external thread. The bracket 110 and the housing 200 can be threadedly connected so that the air type regulating mechanism 100 can be installed in the housing 200, and the air type regulating mechanism 100 is detachably connected to the housing 200 to facilitate the disassembly, assembly or replacement of the air type regulating mechanism 100.

[0193] Optionally, referring to Figure 21 The installation part 240 can be configured as a plug-in slideway, and the installation mating part 115 can be configured as a ball head structure extending in the axial direction. The installation mating part 115 is arranged at the air inlet end of the bracket 110. The ball head structure can be inserted into the plug-in slideway at a certain angle, and the bracket 110 and the housing 200 are fixed by rotating, so that the air type regulating mechanism 100 can be installed in the housing 200, and the air type regulating mechanism 100 is detachably connected to the housing 200 to facilitate the disassembly, assembly or replacement of the air type regulating mechanism 100. When it is necessary to disassemble the air type regulating mechanism 100 from the housing 200, the air type regulating mechanism 100 can be rotated in the reverse direction and the ball head structure can be pulled out of the plug-in slideway.

[0194] Optionally, referring to Figure 23 The installation mating part 115 can be configured as a magnet seat, and the installation part 240 can be configured as a mating magnet. The installation part 240 and the installation mating part 115 can be magnetically mated so that the air type regulating mechanism 100 can be installed in the housing 200, and the air type regulating mechanism 100 is detachably connected to the housing 200 to facilitate the disassembly, assembly or replacement of the air type regulating mechanism 100.

[0195] In some embodiments of the present invention, the driving fan 300 is an axial flow fan.

[0196] Specifically, the driving fan 300 is an axial flow fan, and the blades 310 of the driving fan 300 extend obliquely in the radial direction. When the plurality of blades 310 rotate, the air on the side of the blades 310 away from the guide vane assembly 140 is driven to flow towards the guide vane assembly 140 to form an air flow. When the air flow passes through the blades 310, the blades 310 can guide the air flow to form an oblique air flow. At this time, the air flow has a component velocity in the axial direction and a component velocity in the circumferential direction.

[0197] Furthermore, the guide vane assembly 140 and the air duct adjusting member 120 can play a role in guiding the air flow. Among them, when the guide vane assembly 140 is in the first state, the air duct adjusting member 120 is in the air-diffusing state. The interference of the guide vane assembly 140 and the air duct adjusting member 120 on the air flow is small, and the air flow can still maintain a certain circumferential component velocity when flowing out of the air type regulating mechanism 100, so that the air flow flowing out of the air type regulating mechanism 100 diverges more gently in the radial direction.

[0198] When the guide vane assembly 140 is in the second state, the air duct regulating member 120 is in the air-gathering state. After the air flow impacts on the guide vane assembly 140, the guide vane assembly 140 guides the air flow, and the circumferential component velocity of the air flow is converted into the axial component velocity. After flowing through the guide vane assembly 140, the air flow further flows into the air duct regulating member 120, and the air duct regulating member 120 further regularizes the air flow flowing into it, so that the air flow flowing out of the air duct regulating member 120 is more concentrated in the axial direction.

[0199] Referring to Figure 3 and Figure 14 , in some embodiments of the present invention, the air type regulating mechanism 100 is the above-mentioned air type regulating mechanism 100. The cross-section of the first guide vane 141 is formed as a curve, and the curve is an Archimedean spiral. The bending direction of the curve is opposite to the rotation direction of the blades 310 of the driving fan 300, and the cross-section is perpendicular to the rotation center line of the driving fan 300.

[0200] Specifically, the rotation center line of the driving fan 300 is collinearly arranged with the central axis of the bracket 110. The cross-section of the first guide vane 141 perpendicular to the rotation center line of the driving fan 300 is formed as an Archimedean spiral, and the bending direction of the curve (i.e., the rotation direction of the Archimedean spiral) is opposite to the rotation direction of the blades 310 of the driving fan 300. The rotation direction of the blades 310 of the driving fan 300 is the same as the direction of the circumferential component velocity of the air flow. Such a setting is beneficial to enabling the air flow to flow through the guide vane assembly 140 and contact the guide vane assembly 140, and then the air flow can move along the wall surface of the first guide vane 141 towards the central axis of the bracket 110. The air flow can converge towards the central axis of the bracket 110, thereby being beneficial to increasing the axial component velocity of the air flow, reducing the air outlet area in the radial direction, and making the air outlet strong.

[0201] The structure of the second guide vane 142 can be the same as that of the first guide vane 141 to further ensure the guiding effect of the guide vane assembly 140 on the air flow and facilitate the processing of the guide vane assembly 140.

[0202] As Figure 5 shown, in some other embodiments of the present invention, the cross-sections of the first guide vane 141 and the second guide vane 142 can be straight surfaces to facilitate the processing of the guide vane assembly 140. The shapes of the first guide vane 141 and the second guide vane 142 can be determined according to the air guiding requirements of the air type regulating mechanism 100, and no specific limitation is made here.

[0203] As Figure 28 shown, in some embodiments of the present invention, on the first projection plane, the orthographic projection of the bracket 110 covers the circle where the tips 311 of multiple blades 310 are located, and the first projection plane is perpendicular to the central axis of the bracket 110.

[0204] Specifically, a plurality of blades 310 are arranged in sequence along the axial direction. When driving the fan 300 to work, the plurality of blades 310 are driven to rotate. During the rotation of the blades 310, the surrounding air flow is driven to flow, thereby forming an air flow with a certain flow velocity.

[0205] It should be noted that the "first projection plane" can be understood as the projection plane in the front-back direction or the thickness direction of the fan 1000.

[0206] Furthermore, the air flow generated by the rotation of the blades 310 can flow into the bracket 110. On the first projection plane, the outer edge of the orthographic projection of the bracket 110 can be arranged around the outer peripheral side of the circle where the blade tips 311 of the plurality of blades 310 are located, or the orthographic projection of the bracket 110 just coincides with the above-mentioned circle, which is beneficial to making all the air flow generated by the blades 310 blow into the air duct space, thereby facilitating ensuring that all the air flow generated by the blades 310 flows through the guide vane assembly 140, preventing the air flow from diverging inside the fan 1000, and effectively concentrating the air flow.

[0207] It should be noted that in the radial direction, the position where the blade 310 is farthest from the hub of the driving fan 300 is defined as the blade tip 311 of the blade 310.

[0208] In this application, "on the first projection plane, the orthographic projection of the bracket 110 covers the circle where the blade tips 311 of the plurality of blades 310 are located" can mean that the outer edge of the orthographic projection of the bracket 110 just coincides with the above-mentioned circle, or the outer edge of the orthographic projection of the bracket 110 is located outside the above-mentioned circle (i.e., the above-mentioned circle falls within the orthographic projection of the bracket 110).

[0209] As Figure 28 shown, in some embodiments of the present invention, a part of the blade 310 of the driving fan 300 extends into the bracket 110.

[0210] Specifically, the dimension of the bracket 110 in the radial direction can be greater than the radial dimension of the circle where the blade tips 311 of the plurality of blades 310 are located, and a part of the blade 310 extends into the bracket 110. The blade 310 rotates in the bracket 110 and generates an air flow. The inner wall surface of the bracket 110 can restrict the flow of the air flow, prevent the air flow from diverging before flowing into the guide vane assembly 140, and ensure the flow efficiency of the air flow.

[0211] It can be understood that the end of the blade 310 in the axial direction can be arranged inside the bracket 110, or the entire blade 310 can be arranged inside the bracket 110. The specific arrangement manner of the blade 310 can be determined according to the overall dimensions of the fan 1000, the blade 310, and the bracket 110, and no specific limitation is made here.

[0212] Combined Figure 27 and Figure 29, in some embodiments of the present invention, the fan 1000 further includes an air outlet grille 400, and the air outlet grille 400 is arranged in the air outlet area 220.

[0213] Specifically, the air outlet grille 400 is installed on the housing 200. The air outlet 122 of the air duct adjusting member 120 is directly opposite to the air outlet grille 400 and is located in the air outlet area 220. A mesh structure is formed on the air outlet grille 400, and the air flow can be discharged through the mesh structure. At the same time, the air outlet grille 400 can block the internal structure of the fan 1000, prevent the blades 310 from breaking and flying out through the opening during the operation of the fan 1000, thus causing harm to the user. At the same time, it can prevent the user from being injured due to accidental contact with the blades 310, improve the safety of the fan 1000, and the air outlet grille 400 can also reduce the accumulation of dust and other sundries inside the fan 1000.

[0214] In some embodiments of the present invention, the air outlet grille 400 includes a middle area 410 and an outer ring area 420. The air guiding rib 430 in the middle area 410 is formed into an arc-shaped rib 431, and the air guiding rib 430 in the outer ring area 420 is formed into a straight rib 432.

[0215] Specifically, the middle area 410 and the outer ring area 420 are constructed as rings, and the middle area 410 and the outer ring area 420 are coaxially arranged. The outer ring area 420 is sleeved outside the middle area 410 to realize the partition design of the air outlet grille 400, which is not only beautiful but also can realize the visualization of the air outlet area 220.

[0216] Furthermore, since the area of the air outlet 122 of the air duct adjusting member 120 is different in the air-diffusing state and the air-concentrating state, the air outlet area 220 corresponding to the air outlet 122 of the air duct adjusting member 120 when the fan 1000 is in the air-diffusing mode is different from the air outlet area 220 corresponding to when the fan 1000 is in the air-concentrating mode. When the air duct adjusting member 120 is in the air-concentrating state, the air outlet 122 is directly opposite to the middle area 410. At the same time, the middle area 410 is opposite to the guide vane assembly 140. The middle area 410 of the air outlet grille 400 can further rectify the air flow and further increase the axial component velocity of the air flow. When the air duct adjusting member 120 is in the air-diffusing state, the air outlet 122 is directly opposite to both the outer ring area 420 and the middle area 410.

[0217] Further, the air guiding rib 430 in the middle region 410 is formed as an arc-shaped rib 431, and the air guiding rib 430 in the outer ring region 420 is formed as a straight rib 432. The arc-shaped rib 431 can be designed based on the Archimedes spiral principle. A plurality of arc-shaped ribs 431 are evenly spaced along the circumferential direction, and the bulging directions of the arc-shaped ribs 431 are the same. The arc-shaped rib 431 can effectively reduce the resistance generated by the air guiding rib 430 to the air flow, thereby effectively reducing the resistance of the air outlet grille 400 to the air flow.

[0218] When the fan 1000 is in the air gathering mode, the air outlet 122 is disposed opposite to the middle region 410. After the air flow flows out from the air outlet 122, it flows towards the middle region 410. The arc-shaped rib 431 can play a role in rectifying the air flow to convert the circumferential component velocity of the air flow into the axial component velocity, thereby ensuring the air gathering effect and making the air outlet of the fan 1000 stronger.

[0219] Further, straight ribs 432 extending in the radial direction are provided in the outer ring region 420. A plurality of straight ribs 432 are evenly spaced along the axial direction. When the fan 1000 is in the air dispersing mode, the air outlet 122 is disposed opposite to both the outer ring region 420 and the middle region 410 at the same time. After the air flow flows out from the air outlet 122, it flows towards the outer ring region 420 and the middle region 410. The straight ribs 432 can maintain the circumferential component velocity of the air flow, thereby ensuring the flow area of the air flow in the radial direction and ensuring the air outlet area of the fan 1000 in the radial direction.

[0220] In some embodiments of the present invention, in the axial direction away from the bracket 110, the air outlet end of the straight rib 432 extends obliquely outward in a direction away from the rotation center line of the driving fan 300.

[0221] It should be noted that, in the extending direction of the straight rib 432, the end of the straight rib 432 away from the bracket 110 is defined as the air outlet end of the straight rib 432, and the end of the straight rib 432 close to the bracket 110 is defined as the air inlet end of the straight rib 432.

[0222] Specifically, in the radial direction of the air outlet region 220, the distance between the air inlet end of the straight rib 432 and the rotation center of the driving fan 300 is the smallest, and the distance between the air outlet end of the straight rib 432 and the rotation center of that fan is the largest, so as to realize that the straight rib 432 is arranged at an angle with the rotation center line of the driving fan 300. The straight rib 432 generates little resistance to the air flow and maintains the circumferential component velocity of the air flow, which is beneficial to ensuring the air outlet area of the fan 1000 in the radial direction.

[0223] In some embodiments of the present invention, the inclination angle of the straight rib 432 relative to the rotation center line ranges from 20° to 40°.

[0224] Specifically, the inclination angle of the straight rib 432 with respect to the rotation center line ranges from 20° to 40°. Such a setting can further ensure that the resistance of the straight rib 432 to the air flow is small, maintain the circumferential component velocity of the air flow, and thus is beneficial to ensuring the air outlet area of the fan 1000 in the radial square.

[0225] In some embodiments of the present invention, the air outlet grille 400 is detachably provided on the housing 200.

[0226] Specifically, the air outlet grille 400 can be snap-fitted with the housing 200 to block the open end and prevent the fan 1000 from causing mechanical damage to the user. Moreover, the air outlet grille 400 is detachably connected to the housing 200. When the fan 1000 fails, the air outlet grille 400 can be detached from the housing 200 to facilitate the maintenance of the air flow control mechanism 100 and improve the maintenance convenience of the fan 1000.

[0227] Among them, the air outlet grille 400 can be detachably connected to the housing 200 by means of threaded connection or snap connection, etc. The specific connection method between the air outlet grille 400 and the housing 200 is not specifically limited herein, as long as it is ensured that the air outlet grille 400 is detachably connected to the housing 200.

[0228] In some other embodiments of the present invention, the bracket 110 can directly serve as the housing of the fan 1000, and the air inlet area 210 and the air outlet area 220 can be formed on the bracket 110. And in this case, the air outlet grille 400 is arranged on the bracket 110 and is detachably connected to the bracket 110.

[0229] In some embodiments of the present invention, a rear grille is provided at the rear side of the fan 1000, and the air inlet area 210 can be formed on the rear grille. External air can flow into the fan 1000 through the rear grille. The driving fan 300 can drive the blades 310 to rotate so that the air flowing into the fan 1000 forms an air flow and blows out. And the air flow can flow through the air flow control mechanism 100, and the air flow control mechanism 100 can make the air flow diverge or converge. Then the air flow flows out of the fan 1000 through the air outlet grille 400.
