[0070] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0071] Reference is made below Figures 1 - 22 to describe the air pattern control mechanism 100 and the fan 1000 according to an embodiment of the present invention.

[0072] In combination with Figures 1 to 3 , according to the air pattern control 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 arranged circumferentially, and the plurality of adjusting vanes 121 are rotatably arranged on the bracket 110 so that the air duct adjusting member 120 can be switched between different states; a guiding member 130, the guiding member 130 is movable relative to the bracket 110, and the guiding member 130 is connected to the plurality of adjusting vanes 121 to drive the plurality of adjusting vanes 121 to rotate synchronously.

[0073] Specifically, the plurality of adjusting vanes 121 are evenly spaced along the circumferential direction of the bracket 110. The adjusting vanes 121 can guide the air flow. Different rotation angles of the adjusting vanes 121 relative to the bracket 110 can make the air duct adjusting member 120 have different states, so that the air duct adjusting member can play different guiding effects on the air flow, and adjust the air outlet range and the air outlet feeling of the air flow flowing out of the air duct adjusting member 120.

[0074] Furthermore, the guiding member 130 can move relative to the bracket 110, and the plurality of adjusting vanes 121 are all drivably connected to the guiding member 130. When the guiding member 130 moves relative to the bracket 110, the guiding member 130 can drive the plurality of adjusting vanes 121 to rotate synchronously to adjust the rotation angle of the adjusting vanes 121 relative to the bracket 110, so that 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.

[0075] Among them, the guiding member 130 can rotate relative to the bracket 110, and when the guiding member 130 rotates relative to the bracket 110, it can drive the plurality of adjusting vanes 121 to rotate synchronously; the guiding member 130 can move linearly relative to the bracket 110, and when the guiding member 130 moves linearly relative to the bracket 110, the guiding member 130 can drive the plurality of adjusting vanes 121 to rotate synchronously.

[0076] 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.

[0077] The present application sets a guide member 130, and the guide member 130 can move relative to the bracket 110 and is transmission-connected with multiple adjustment plates 121, so that the guide member 130 can drive the adjustment plates 121 to rotate relative to the bracket 110 when it moves relative to the bracket 110. By rotating the adjustment plates 121 relative to the bracket 110 to adjust the rotation angle of the adjustment plates 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.

[0078] According to the wind type control mechanism 100 of the present invention, a guide member 130 that can move relative to the bracket 110 is provided, and the guide member 130 is transmission-connected with a plurality of adjustment plates 121, so that the guide member 130 can drive the adjustment plates 121 to rotate relative to the bracket 110 when it moves relative to the bracket 110. By rotating the adjustment plates 121 relative to the bracket 110 to adjust the rotation angle of the adjustment plates 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 different usage requirements of users and improve the user experience.

[0079] It should be noted that the shape of the guide member 130 can be constructed as a polygonal ring or a circular ring. The specific shape of the guide member 130 is not limited here, as long as the guide member 130 can rotate relative to the bracket 110.

[0080] Combination Figures 1 to 3 In some embodiments of the present invention, the guide member 130 can reciprocate relative to the bracket 110 to drive the adjustment piece 121 to rotate.

[0081] Specifically, the guide member 130 can be constructed to move relative to the bracket 110 in a direction parallel to the central axis of the bracket 110. When the guide member 130 moves forward to an extreme position relative to the bracket 110, the guide member 130 drives the adjusting piece 121 to rotate to an extreme angle relative to the bracket 110, and the air duct adjusting piece 120 is in one working state; when the guide member 130 moves backward to an extreme position relative to the bracket 110, the guide member 130 drives the adjusting piece 121 to rotate to another extreme angle relative to the bracket 110, and the air duct adjusting piece 120 is in another working state.

[0082] It should be noted that the "front-back direction" refers to the direction parallel to the central axis of the bracket 110, "forward" refers to the direction of moving from the air inlet side to the air outlet side of the air type regulating mechanism 100, and "backward" refers to the direction of moving from the air outlet side to the air inlet side of the air type regulating mechanism 100.

[0083] Further, the guide member 130 can reciprocate forward or backward relative to the bracket 110, so that the adjusting piece 121 can be adjusted between different limit angles, thereby enabling the air duct adjusting member 120 to switch between different states.

[0084] In some embodiments of the present invention, the air duct adjusting member 120 switches between a wind-gathering state and a wind-dispersing state, and the area of the air outlet 122 of the air duct adjusting member 120 in the wind-gathering state is smaller than the area of the air outlet 122 in the wind-dispersing state.

[0085] Specifically, the guide member 130 can reciprocate along the direction of its central axis relative to the bracket 110. The guide member 130 drives the adjusting piece 121 relative to the bracket 110, and makes the air outlet end of the adjusting piece 121 approach or move away from the central axis of the bracket 110.

[0086] Further, when the air duct adjusting member 120 is in the wind-gathering state, compared with when the air duct adjusting member 120 is in the wind-dispersing state, the air outlet end of the adjusting piece 121 moves in a direction relatively closer to the central axis of the air duct adjusting member 120. When the air duct adjusting member 120 is in the wind-dispersing state, the air outlet end of the adjusting piece 121 is arranged relatively farther away from the central axis of the air duct adjusting member 120 than when it is in the wind-gathering state. Thus, the area of the air outlet 122 of the air duct adjusting member 120 defined by a plurality of adjusting pieces 121 in the wind-gathering state is smaller than the area of the air outlet 122 in the wind-dispersing state.

[0087] Further, when the air duct adjusting member 120 is in the wind-dispersing state, the area of the air outlet 122 of the air duct adjusting member 120 increases, and the interference of the adjusting piece 121 on the circumferential component velocity of the air flow is small. When the air flow is discharged from the air duct adjusting member 120, it can still maintain a certain circumferential component velocity, so that the air outlet area is large and the air outlet is gentle, realizing the wind-dispersing state of the air duct adjusting member 120.

[0088] When the air duct adjusting member 120 is in the wind-gathering state, the guide member 130 drives a plurality of adjusting members 121 to gather towards the direction close to the central axis of the air outlet of the formed air duct adjusting member 120, and the circumferential component velocity of the air flow is converted into an axial component velocity, so that the air outlet area is small and the wind feeling is strong.

[0089] Combined with Figures 1 to 3, in some embodiments of the present invention, the adjusting piece 121 includes a rotating part 1211 and a connecting part 1212 that are rotatably connected. The rotating part 1211 is rotatably arranged on the bracket 110; the guiding ring 130 is provided with a mounting seat 131, and the connecting part 1212 of each adjusting piece 121 is rotatably matched with the mounting seat 131. The guiding member 130 is configured to reciprocate relative to the bracket 110 to drive the adjusting piece 121 to rotate relative to the bracket 110 through the connecting part 1212.

[0090] Specifically, the adjusting piece 121 is provided with a rotating part 1211 and a connecting part 1212. The adjusting piece 121 is rotatably connected to the bracket 110 through the rotating part 1211, and the connecting part 1212 of the adjusting piece 121 is rotatably connected to the mounting seat 131 on the guiding member 130.

[0091] Further, the guiding member 130 can reciprocate relative to the bracket 110 along the axial direction parallel to the bracket 110, and the guiding member 130 drives the mounting seat 131 to move synchronously. When the guiding member 130 moves relative to the bracket 110, the guiding member 130 can push and pull the connecting part 1212 through the mounting seat 131. While the rotating part 1211 rotates relative to the mounting seat 131, it moves along the axial direction. The connecting part 1212 further pushes and pulls the rotating part 1211. Since the rotating part 1211 is rotatably connected to the bracket 110, when the connecting part 1212 pushes and pulls the rotating part 1211, the rotating part 1211 rotates and drives the adjusting piece 121 to rotate, thereby adjusting the distance between the air outlet end of the adjusting piece 121 and the central axis of the air duct adjusting member 120, so as to adjust the area of the air outlet 122 of the air duct adjusting member 120, enabling the air duct adjusting member 120 to switch between the air-gathering state and the air-dispersing state, thus facilitating the adjustment of the working state of the air type control mechanism 100.

[0092] Furthermore, the air duct adjusting member 120 has a diffusing state and a wind-concentrating state. When it is necessary to switch the air duct adjusting member 120 to the wind-concentrating state, the guiding member 130 moves in a direction parallel to the central axis of the bracket 110 towards the air duct adjusting member 120. The guiding member 130 can push the connecting portion 1212 through the mounting seat 131. While the rotating portion 1211 rotates relative to the mounting seat 131, it moves axially towards the air outlet 122. The connecting portion 1212 further pushes the rotating portion 1211 to make it rotate. The rotating portion 1211 drives the air outlet end of the adjusting piece 121 to rotate towards the central axis of the air duct adjusting member 120, thereby reducing the distance between the air outlet end of the adjusting piece 121 and the central axis of the air duct adjusting member 120. The air outlet 122 of the air duct adjusting member 120 converges towards the central axis of the air duct adjusting member 120 to reduce the area of the air outlet 122 of the air duct adjusting member 120, so that the air duct adjusting member 120 is switched to the wind-concentrating state. The plurality of adjusting pieces 121 can regularize the air flow to convert the circumferential component velocity of the air flow into the axial component velocity. When the air flow flows out, the air outlet intensity is large and the wind feeling is strong.

[0093] When it is necessary to switch the air duct adjusting member 120 to the diffusing state, the guiding member 130 moves in a direction parallel to the central axis of the bracket 110 away from the air duct adjusting member 120. The guiding member 130 can pull the connecting portion 1212 through the mounting seat 131. While the rotating portion 1211 rotates relative to the mounting seat 131, it moves axially away from the air outlet 122. The connecting portion 1212 further pulls the rotating portion 1211 to make it rotate. The rotating portion 1211 drives the air outlet end of the adjusting piece 121 to rotate away from the central axis of the air duct adjusting member 120, thereby increasing the distance between the air outlet end of the adjusting piece 121 and the central axis of the air duct adjusting member 120. The air outlet 122 of the air duct adjusting member 120 expands away from its central axis to increase the area of the air outlet 122 of the air duct adjusting member 120, so that the air duct adjusting member 120 is switched to the diffusing state. The interference of the adjusting piece 121 on the circumferential component velocity of the air flow is small. When the air flow is discharged from the air duct adjusting member 120, it can still maintain a certain circumferential wind speed, so that the air outlet area is large and the wind feeling is gentle.

[0094] It can be understood that the adjusting piece 121 can be arranged on the guiding member 130, the rotating portion 1211 can be arranged on the guiding member 130, and the mounting seat 131 can be arranged on the adjusting piece 121. The technical effects achieved by this structure are the same as those of the above structure, and will not be elaborated here one by one.

[0095] Combined with Figure 3 、 Figure 4 、 Figure 8 and Figure 9, in some embodiments of the present invention, the rotating part 1211 is arranged at the air outlet end of the adjusting piece 121. A plurality of rotating matching parts 118 are arranged at the air outlet end of the bracket 110. The plurality of rotating matching parts 118 are arranged at intervals along the circumferential direction of the bracket 110, and the plurality of rotating matching parts 118 are arranged in one-to-one correspondence with the rotating parts 1211 of the plurality of adjusting pieces 121. The rotating part 1211 is rotatably connected to the rotating matching part 118 through a pin shaft, so as to realize the rotatable connection between the adjusting piece 121 and the bracket 110. And the rotation axis of the rotating part 1211 and the rotating matching part 118 is perpendicular to the central axis of the bracket 110. At the same time, the rotation axis of the rotating part 1211 and the rotating matching part 118 is perpendicular to the direction in which the central axis of the bracket 110 extends towards the adjusting piece 121.

[0096] Combined with Figure 3 and Figure 9 , in some embodiments of the present invention, the guiding part 130 is sleeved outside the bracket 110.

[0097] Specifically, the guiding part 130 is sleeved on the radial outside of the bracket 110. The bracket 110 can provide an installation position for the guiding part 130 to facilitate the assembly of the guiding part 130. And the guiding part 130 being sleeved outside the bracket 110 can effectively reduce the size of the air flow pattern regulating mechanism 100 in the axial direction, thereby reducing the volume of the air flow pattern regulating mechanism 100, which is beneficial to realizing the miniaturized design of the air flow pattern regulating mechanism 100.

[0098] Of course, it can be understood that the guiding part 130 can also be embedded in the bracket 110, as long as it is ensured that the guiding part 130 and the bracket 110 can be coaxial and relatively movable. The specific relative position relationship between the guiding part 130 and the bracket 110 is not specifically limited herein.

[0099] Combined with Figures 3 to 5 , in some embodiments of the present invention, the guiding part 130 is provided with a first guiding part 132, and the bracket 110 is provided with a second guiding part 111. The first guiding part 132 and the second guiding part 111 are in sliding fit to guide the moving direction of the guiding part 130.

[0100] Specifically, a first guiding part 132 is arranged on the guiding part 130, a second guiding part 111 is arranged on the bracket 110, and the first guiding part 132 and the second guiding part 111 are in sliding fit in a direction parallel to the central axis of the bracket 110 to guide the guiding part 130 to move relative to the bracket 110 in a direction parallel to the central axis of the bracket 110.

[0101] Among them, a plurality of first guiding members 132 are provided. Correspondingly, a plurality of second guiding members 111 are provided. The plurality of first guiding members 132 and the plurality of second guiding members 111 are arranged in one-to-one correspondence and are in sliding fit to improve the fitting reliability between the guiding member 130 and the bracket 110.

[0102] Combined Figures 3 to 5 , in some embodiments of the present invention, the first guiding member 132 is a guiding groove or a guiding protrusion provided on the inner wall of the guiding member 130, and the second guiding member 111 is a guiding groove or a guiding protrusion provided on the outer peripheral wall 1102 of the bracket 110. The guiding protrusion and the guiding groove are in sliding fit.

[0103] Specifically, the first guiding member 132 can be configured as a guiding groove provided on the inner wall of the guiding member 130. The guiding groove is recessed from the inner wall of the guiding member 130 in the radial direction away from the bracket 110. Correspondingly, the second guiding member 111 can be configured as a guiding protrusion provided on the outer peripheral wall 1102 of the bracket 110. The guiding protrusion bulges from the outer peripheral wall 1102 of the bracket 110 in the radial direction toward the guiding member 130, and the guiding protrusion can be inserted into the guiding groove and slide in the guiding groove, thereby realizing the sliding fit between the guiding protrusion and the guiding groove.

[0104] Optionally, the first guiding member 132 can be a guiding protrusion provided on the inner wall of the guiding member 130. The guiding protrusion bulges from the inner wall of the guiding member 130 in the radial direction toward the bracket 110. Correspondingly, the second guiding member 111 can be configured as a guiding groove provided on the outer peripheral wall 1102 of the bracket 110. The guiding groove is recessed from the outer peripheral wall 1102 of the bracket 110 in the radial direction away from the guiding member 130. The guiding protrusion can be inserted into the guiding groove and slide in the guiding groove, thereby realizing the sliding fit between the guiding protrusion and the guiding groove.

[0105] Among them, both the guiding groove and the guiding protrusion extend along the reverse direction parallel to the central axis of the bracket 110 to guide the guiding member 130 to move relative to the bracket 110 in a direction parallel to the central axis of the bracket 110.

[0106] Combined Figure 4 and Figure 11 , in some embodiments of the present invention, a limiting block 140 is provided in the guiding groove. The limiting block 140 is adapted to abut against the guiding protrusion to limit the moving displacement of the guiding member 130.

[0107] Specifically, since the adjusting piece 121 is arranged at the air outlet end of the bracket 110, the guiding member 130 can be arranged at a position of the bracket 110 close to the air outlet end to reduce the size of the connecting portion 1212 and facilitate the guiding member 130 to drive the adjusting piece 121.

[0108] For ease of description, an example is given in which the guiding protrusion is provided on the bracket 110 and the guiding groove is provided on the guiding member 130.

[0109] The guiding protrusion extends from the air inlet end of the bracket 110 along a direction parallel to the central axis of the bracket 110 towards the air outlet end of the bracket 110, and one end of the guiding protrusion close to the air outlet end of the bracket 110 is spaced from the air outlet end of the bracket 110. A limiting block 140 is provided on one side of the guiding groove close to the air outlet end of the guiding member 130. The limiting block 140 can be in abutting cooperation with the end of the guiding protrusion close to the air outlet end of the bracket 110, so as to limit the moving distance of the guiding member 130 relative to the bracket 110. The rotation angle of the adjusting piece 121 is related to the moving distance of the guiding member 130 relative to the bracket 110, so that the rotation angle of the adjusting piece 121 can be limited, and the guiding effect of the air duct adjusting member 120 on the air flow can be prevented from being caused by an unreasonable rotation angle of the adjusting piece 121.

[0110] It can be understood that when the guiding protrusion is provided on the guiding member 130 and the guiding groove is provided on the bracket 110, the arrangement manners of the guiding protrusion and the limiting block 140 are the same as the above arrangement manners, and the achieved technical effects are the same, and will not be elaborated here one by one.

[0111] Combined with Figures 1 to 3 and Figure 10 , in some embodiments of the present invention, the air type regulation mechanism 100 further includes a plurality of guide vanes 150. The plurality of guide vanes 150 are rotatably arranged on the bracket 110 and the plurality of guide vanes 150 are spaced along the circumferential direction of the bracket 110.

[0112] Specifically, an annular installation space 114 is provided in the bracket 110. The plurality of guide vanes 150 are sequentially and spaced along the circumferential direction in the installation space 114. The guide vane 150 has an air inlet end and an air outlet end. The air flow flows from the air inlet end of the guide vane 150 to the air outlet end of the guide vane 150 through the gap between two adjacent guide vanes 150. The guide vane 150 can play a role in guiding the air flow, so as to adjust the flow direction of the air flow.

[0113] Further, the guide vane 150 is rotatably arranged on the bracket 110 to facilitate adjusting the guiding effect of the guide vane 150 on the air flow, so as to adjust the wind feeling and the air outlet area when the air flow flows out.

[0114] Combined with Figure 3 and Figure 4 , in some embodiments of the present invention, a support seat 112 is provided at the center of the bracket 110; both ends of each guide vane 150 are rotatably arranged on the bracket 110 and the support seat 112 through a rotating shaft 151 respectively, and a matching column 152 is provided at one end of each guide vane 150; the matching columns 152 of the plurality of guide vanes 150 are matched with the guiding member 130 to drive the guide vanes 150 to rotate when the guiding member 130 moves.

[0115] Specifically, referring to Figure 10 , the support base 112 is disposed at the central position of the bracket 110 and jointly defines an annular installation space 114 with the bracket 110. Each guide vane 150 is provided with a rotating shaft 151. A plurality of first holes 1121 are arranged on the support base 112 at equal intervals in the circumferential direction, and a plurality of second holes 116 are arranged on the bracket 110 at equal intervals in the circumferential direction. The guide vane 150 is rotatably inserted and fitted with the first holes 1121 and the second holes 116 through the rotating shaft 151 respectively, so as to realize the rotatable connection of the guide vane 150 with the bracket 110 and the support base 112 respectively.

[0116] Wherein, the support base 112 can be connected with the bracket 110 through the connecting rib 115 to improve the connection reliability of the support base 112, and is beneficial to improving the assembly reliability of the guide vane 150 and the stability during rotation.

[0117] Furthermore, a mating post 152 is provided at one end of each guide vane 150 close to the bracket 110, and the mating post 152 is spaced from the rotating shaft 151. The mating post 152 is used to cooperate with the guiding member 130. When the guiding member 130 moves relative to the bracket 110, it can drive the mating post 152 to move. At the same time, the mating post 152 drives the rotating shaft 151 to rotate, and the rotation can drive the guide vane 150 to rotate, so as to adjust the guiding effect of the guide vane 150 on the air flow.

[0118] It can be understood that the guiding member 130 can drive the mating post 152 to move by pressing; or the guiding member 130 can push and pull the mating post 152 through the connecting structure to make it move. The specific driving method can be determined according to actual processing and production, and is not specifically limited herein.

[0119] Combined with Figures 3 to 5 , in some embodiments of the present invention, the guiding member 130 is provided with a plurality of first guiding grooves 133, and the mating post 152 extends into the first guiding grooves 133 and is slidably fitted with the first guiding grooves 133.

[0120] Specifically, the plurality of first guiding grooves 133 are arranged in one-to-one correspondence with the mating posts 152 of the plurality of guide vanes 150. The mating post 152 can pass through the first guiding groove 133 and slide in the first guiding groove 133. When the guiding member 130 moves relative to the bracket 110, the guiding member 130 drives the first guiding groove 133 to move. The mating post 152 slides in the first guiding groove 133. At the same time, the groove wall of the first guiding groove 133 can press against the mating post 152 to make it move, and the mating post 152 drives the rotating shaft 151 to rotate, so as to drive the guide vane 150 to rotate through the rotating shaft 151, so as to adjust the deflection angle of the guide vane 150 and realize the adjustment of the guide vane 150.

[0121] Combined withFigures 3 to 5 In some embodiments of the present invention, the bracket 110 is provided with a plurality of second guiding grooves 113, and the plurality of second guiding grooves 113 are in one-to-one correspondence and cooperation with the plurality of first guiding grooves 133. Each fitting post 152 passes through the corresponding second guiding groove 113 and is in sliding cooperation with the first guiding groove 133.

[0122] Specifically, the plurality of second guiding grooves 113 are sequentially arranged at intervals in the circumferential direction of the bracket 110, and each second guiding groove 113 is in one-to-one correspondence and adjacent to each second hole 116. At the same time, the plurality of second guiding grooves 113 and the plurality of first guiding grooves 133 are arranged opposite to each other in the radial direction. The fitting post 152 passes through the second guiding groove 113 and is in sliding cooperation with the corresponding first guiding groove 133.

[0123] Furthermore, when the guiding member 130 moves relative to the bracket 110, the first guiding groove 133 drives the fitting post 152 to slide relatively within the first guiding groove 133. At the same time, the groove wall of the first guiding groove 133 can drive the fitting post 152 to slide within the second guiding groove 113. The fitting post 152 drives the guide vane 150 to rotate around the central axis of the rotating shaft 151, thereby adjusting the guiding effect of the guide vane 150 on the airflow.

[0124] Wherein, the movement track of the fitting post 152 is: an arc movement with the central axis of the rotating shaft 151 as the rotation center and the distance between the fitting post 152 and the rotating shaft 151 as the radius. Therefore, the second guiding groove 113 can be configured as a circular arc groove structure surrounding the second hole 116. One end of the second guiding groove 113 is arranged closer to the air outlet end of the bracket 110 than the other end, so that the second guiding groove 113 can be adapted to the movement track of the fitting post 152, and the second guiding groove 113 can limit the movement range of the fitting post 152 to ensure that it can move within the designed range, thereby ensuring that the guide vane 150 can rotate within the designed range. Specifically, the size of the second guiding groove 113 can be designed according to the rotation range requirements of the actual guide vane 150, and no specific limitation is made here.

[0125] Combined with Figure 1 and Figure 2, in some embodiments of the present invention, the guide vane 150 has a first state and a second state. A plurality of guide vanes 150 are rotatably mounted on the bracket 110 to facilitate the switching of the guide vane 150 between the first state and the second state. In the first state, in the direction of the central axis of the installation space 114 extending, the guide vane 150 is arranged obliquely, that is, the air outlet end of the guide vane 150 deflects towards the direction close to the inner peripheral wall 1101 of the bracket 110 relative to its air inlet end. At this time, the extending direction of the guide vane 150 is basically the same as the flowing direction of the air flow. The adjustment effect of the guide vane 150 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 in a conical shape after flowing out, and the air flow is in a divergent state when flowing out, and the wind feeling is soft.

[0126] It should be noted that the air flow flowing through the air flow type regulating mechanism 100 is spiral, and it has a circumferential component velocity and an axial component velocity.

[0127] In the second state, the air outlet end of the guide vane 150 deflects towards the direction deviating from the inner peripheral wall 1101 of the bracket 110 relative to its air inlet end. The guide vane 150 can be perpendicular to the air outlet surface. At this time, the extending direction of the guide vane 150 is different from the flowing direction of the air flow. After the air flow impacts the guide vane 150, the guide vane 150 can guide the air flow, and the circumferential component velocity of the air flow is converted into the axial component velocity, so that the air flow is in a cylindrical shape after flowing out. The flow velocity of the air flow is large, and the flow range is small. The air flow is in a converging state, and the wind feeling is strong.

[0128] It can be understood 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 guide vane 150 can be perpendicular to the air outlet surface; there can also be a certain deviation between the angle between the guide vane 150 and the air outlet surface and just being perpendicular, so as to reduce the processing accuracy requirements of the air flow type regulating mechanism 100. The specific angle setting can be determined according to the actual air outlet requirements, and no specific limitation is made here, as long as the adjustment effect of the guide vane 150 on the air flow is ensured.

[0129] Further combined with Figures 1 to 3, the air duct adjusting member 120 is located on the air outlet side of the plurality of guide vanes 150. The air flow flows into the air duct adjusting member 120 after passing through the plurality of guide vanes 150. The area of the air outlet 122 of the air duct adjusting member 120 can be adjusted to further adjust the flow range and intensity of the air flow through the area of the air outlet 122. When the plurality of guide vanes 150 are in the first state, the air duct adjusting member 120 is in the air-diffusing state. After the air flow flows out of the guide vanes 150, the air duct adjusting member 120 can further guide the air flow to maintain the circumferential component velocity of the air flow and realize the air-diffusing mode of the air pattern regulating mechanism 100, ensuring the diffusing effect when the air flow flows out of the air pattern regulating mechanism; when the plurality of guide vanes 150 are in the second state, the air duct adjusting member 120 is in the air-concentrating state. After the air flow flows out of the guide vanes 150, the air duct adjusting member 120 can further rectify the air flow to realize the air-concentrating mode of the air pattern regulating mechanism 100, ensuring the concentrating effect when the air flow flows out of the air pattern regulating mechanism 100.

[0130] The process of the air pattern regulating mechanism 100 described in the embodiments of the present invention adjusting its working state will be briefly described below.

[0131] When it is necessary to adjust the air pattern regulating mechanism 100 from the air-diffusing mode to the air-concentrating mode, the air duct adjusting member 120 switches from the air-diffusing state to the air-concentrating state, and at the same time, the guide vanes 150 switch from the first state to the second state.

[0132] The guiding member 130 moves in a direction parallel to the central axis of the bracket 110 towards the air duct adjusting member 120. The guiding member 130 can push the connecting portion 1212 through the mounting seat 131. While the rotating portion 1211 rotates relative to the mounting seat 131, it moves in the axial direction towards the air outlet 122. The connecting portion 1212 further pushes the rotating portion 1211 to make it rotate. The rotating portion 1211 drives the air outlet end of the adjusting piece 121 to rotate towards the central axis of the air duct adjusting member 120, thereby reducing the distance between the air outlet end of the adjusting piece 121 and the central axis of the air duct adjusting member 120. The air outlet 122 of the air duct adjusting member 120 converges towards the central axis of the air duct adjusting member 120 to reduce the area of the air outlet 122 of the air duct adjusting member 120, so that the air duct adjusting member 120 switches to the air-concentrating state. The plurality of adjusting pieces 121 can regularize the air flow to convert the circumferential component velocity of the air flow into the axial component velocity, and the air outlet intensity when the air flow flows out is large and the wind feeling is strong.

[0133] Meanwhile, the guiding member 130 drives the mating post 152 to slide within the first guiding groove 133. The inner wall surface of the first guiding groove 133 can drive the mating post 152 to slide within the second guiding groove 113. The mating post 152 drives the rotating shaft 151 to rotate and drives the guide vane 150 to rotate. The air outlet end of the guide vane 150 rotates in a direction deviating from the inner peripheral wall 1101 of the bracket 110. After the air flow impinges on the guide vane 150, the guide vane 150 can guide the air flow. The circumferential component velocity of the air flow is converted into an axial component velocity, so that the air flow is in a cylindrical shape after flowing out. The flow velocity of the air flow is high, and the flow range is small. The air flow is in a converging state, and the wind feeling is strong.

[0134] When it is necessary to adjust the air type regulating mechanism 100 from the air converging mode to the air diffusing mode, the air duct adjusting member 120 switches from the air converging state to the air diffusing state, and at the same time, the guide vane 150 switches from the second state to the first state.

[0135] The guiding member 130 moves away from the air duct adjusting member 120 along a direction parallel to the central axis of the bracket 110. The guiding member 130 can pull the connecting portion 1212 through the mounting seat 131. While the rotating portion 1211 rotates relative to the mounting seat 131, it moves away from the air outlet 122 in the axial direction. The connecting portion 1212 further pulls the rotating portion 1211 to make it rotate. The rotating portion 1211 drives the air outlet end of the adjusting piece 121 to rotate in a direction away from the central axis of the air duct adjusting member 120, thereby increasing the distance between the air outlet end of the adjusting piece 121 and the central axis of the air duct adjusting member 120. The air outlet 122 of the air duct adjusting member 120 expands in a direction away from its central axis to increase the area of the air outlet 122 of the air duct adjusting member 120, so that the air duct adjusting member 120 switches to the air diffusing state. 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 wind speed when discharging from the air duct adjusting member 120, so that the air outlet area is large and the wind feeling is gentle.

[0136] Meanwhile, the guiding member 130 drives the mating post 152 to slide within the first guiding groove 133. The inner wall surface of the first guiding groove 133 can drive the mating post 152 to slide within the second guiding groove 113. The mating post 152 drives the rotating shaft 151 to rotate and drives the guide vane 150 to rotate. The air outlet end of the guide vane 150 rotates in a direction approaching the inner peripheral wall 1101 of the bracket 110. At this time, the extending direction of the guide vane 150 is basically the same as the flowing direction of the air flow. The adjustment effect of the guide vane 150 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 in a conical shape after flowing out, and the air flow is in a divergent state when flowing out, and the wind feeling is gentle.

[0137] Thus, the guiding member 130 is used to realize the working state of adjusting the air type regulating mechanism 100.

[0138] Combined with Figure 3 、Figure 6 and Figure 7 In some embodiments of the present invention, a connecting convex base 153 is provided at one end of the guide vane 150. The connecting convex base 153 protrudes from the guide vane 150. One of the rotating shafts 151 and the fitting column 152 are arranged on the connecting convex base 153.

[0139] Specifically, a connecting convex base 153 is provided at one end of the guide vane 150 close to the bracket 110. The connecting convex base 153 can increase the cross-sectional area of the end of the guide vane 150. The fitting column 152 of the guide vane 150 and the rotating shaft 151 at one end close to the bracket 110 can be arranged on the connecting convex base 153 to facilitate the arrangement of the fitting column 152 and the rotating shaft 151.

[0140] Furthermore, the connecting convex base 153 can be in anti-contact fit with the bracket 110, which is beneficial to improving the stability of the guide vane 150 during rotation. And the thickness of the connecting convex base 153 can be greater than the thickness of the guide vane 150, so that the structural strength of the connecting convex base 153 is greater than that of the guide vane 150, effectively reducing the risk of the guide vane 150 directly breaking due to the anti-contact between the guide vane 150 and the bracket 110.

[0141] Combined with Figure 9 and Figure 10 In some embodiments of the present invention, the wind type regulating mechanism 100 further includes an electric driving device, and the electric driving device cooperates with the guiding member 130 to drive the guiding member 130 to reciprocate.

[0142] Specifically, the output end of the electric driving device is connected to the guiding member 130 so that when the electric driving device outputs power, it can drive the guiding member 130 to reciprocate, enabling the wind type regulating mechanism 100 to switch between the diffused wind mode and the concentrated wind mode, and without manual operation, effectively improving the adjustment convenience of the wind type regulating mechanism 100.

[0143] Referring to Figure 9 In some embodiments of the present invention, the electric driving device includes a driving motor 161 and a connecting rod assembly 162. The connecting rod assembly 162 is respectively connected to the driving motor 161 and the guiding member 130 to drive the guiding member 130 to move.

[0144] Specifically, a connecting rod assembly 162 is provided at the output end of the drive motor 161, and a driving portion 135 is provided on the guide member 130. The connecting rod assembly 162 is connected to the driving portion 135. At this time, the connecting rod assembly 162 and the guide member 130 cooperate to define a crank-slider mechanism. The guide member 130 serves as the slider in the crank-slider mechanism, and the connecting rod assembly 162 serves as the crank in the crank-slider mechanism. When the drive motor 161 outputs power, the drive motor 161 can drive the crank to perform reciprocating movement over a small distance (i.e., the drive motor 161 drives the connecting rod assembly 162 to perform reciprocating linear movement over a small distance). The crank drives the slider to perform reciprocating linear movement over a small distance, that is, the connecting rod assembly 162 drives the guide member 130 to perform reciprocating linear rotation over a small distance. When the guide member 130 performs reciprocating linear movement, the guide member 130 can drive the guide vane 150 and the adjusting piece 121 to perform reciprocating rotation, so that the guide vane 150 can be switched between the first state and the second state, and at the same time, the air duct adjusting member 120 can be switched between the air-diffusing state and the air-concentrating state, thereby realizing the switching of the air pattern control mechanism 100 between the air-diffusing mode and the air-concentrating mode.

[0145] When the guide member 130 moves to one extreme position, the adjustment of the working state of the air pattern control mechanism 100 is completed.

[0146] Combined Figures 10 to 13 , in some embodiments of the present invention, the electric drive device includes: a drive ring 163, the drive ring 163 is in threaded cooperation with the bracket 110 for reciprocating movement, the drive ring 163 cooperates with the guide member 130 to drive the guide member 130 to move, and the drive ring 163 is provided with an engaging tooth portion 164; a drive motor 161 and a drive gear 165, the drive motor 161 is connected to the drive gear 165, and the drive gear 165 meshes with the engaging tooth portion 164.

[0147] Specifically, the drive ring 163 is sleeved on the radial outer side of the bracket 110, and an internal thread 167 is provided on the inner wall surface of the drive ring 163. An external thread is provided on the outer peripheral wall 1102 of the bracket 110. The drive ring 163 is in threaded cooperation with the bracket 110, so that the drive ring 163 can reciprocate relative to the bracket 110 in the axial direction.

[0148] Further, the drive ring 163 is located at the air inlet end of the guide member 130 to avoid the air duct adjusting member 120. A mating protrusion 136 is provided at the air inlet end of the guide member 130. A mating groove 166 is provided at the end of the drive ring 163 opposite to the guide member 130. The mating protrusion 136 can be embedded in the mating groove 166 and can rotate in the mating groove 166, thereby realizing the cooperation between the drive ring 163 and the guide member 130, so as to facilitate the drive ring 163 to drive the guide member 130 to move.

[0149] Of course, it is understandable that the drive ring 163 and the guide member 130 may also be constructed in other matching modes, as long as the drive ring 163 can drive the guide member 130 to move back and forth.

[0150] Further integration Figure 10 and Figure 13 The outer wall surface of the driving ring 163 is provided with a meshing tooth portion 164, and the output end of the driving motor 161 is provided with a driving gear 165, and the driving gear 165 can mesh with the meshing tooth portion 164. When the driving motor 161 outputs power, the driving gear 165 rotates and drives the meshing tooth portion 164 meshing therewith to rotate reciprocatingly, and the meshing tooth portion 164 drives the driving ring 163 to rotate reciprocatingly, and at the same time, the driving ring 163 reciprocates in the axial direction relative to the bracket 110, and the driving ring 163 drives the guide member 130 to reciprocate in the axial direction, and the guide member 130 can drive the guide vane 150 and the adjusting piece 121 to reciprocate, so that the guide vane 150 can switch between the first state and the second state, and at the same time, the air duct adjusting member 120 can switch between the wind dispersion state and the wind gathering state, thereby realizing the switching of the wind type control mechanism 100 between the wind dispersion mode and the wind gathering mode.

[0151] When the guide member 130 moves to the extreme position on one side, the working state adjustment of the wind pattern control mechanism 100 is completed.

[0152] The driving motor 161 may be configured as a stepping motor, which reciprocates to drive the driving ring 163 to reciprocate.

[0153] like Figure 14 As shown, in some embodiments of the present invention, the guide member 130 is provided with a toggle rod 134, and the toggle rod 134 is toggled to drive the guide member 130 to reciprocate.

[0154] Specifically, the toggle rod 134 is arranged on the guide member 130 and extends in the radial direction away from the central axis of the guide member 130. The user can drive the guide member 130 to move back and forth in the axial direction by the toggle rod 134, thereby manually driving the guide member 130 to move, and then the working mode of the manual adjustment of the wind type control mechanism 100 can be realized.

[0155] Combination Figure 20 and Figure 21 The fan 1000 according to the present invention comprises: a wind type regulating mechanism 100 , which is the above-mentioned wind type regulating mechanism 100 ; and a driving fan 300 , which is arranged on the air inlet side of the air duct regulating member 120 .

By rotating the adjustment plates 121 relative to the bracket 110 to adjust the rotation angle of the adjustment plates 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.

[0160] Specifically, the shell 200 is constructed as a cylindrical structure with a cavity. The shell 200 can serve as an installation carrier for the driving fan 300 and the wind type control mechanism 100. The driving fan 300 and the wind type control mechanism 100 can be installed in the shell 200. The shell 200 can protect the driving fan 300 and the wind type control mechanism 100 to prevent damage to the fan 1000 due to external debris entering the driving fan 300 or the wind type control mechanism 100.

An air outlet area 220 is formed on the front side of the housing 200. The air outlet area 220 can be constructed as an opening formed on the front side of the housing 200. The driving fan 300 and the wind type control mechanism 100 can be installed in the housing 200 through the air outlet area 220 to facilitate the assembly of the fan 1000.

[0162] Optionally, the driving fan 300 and the wind type control mechanism can be arranged outside the housing 200. The specific arrangement of the driving fan 300 can be determined according to the actual installation requirements of the fan 1000 and is not specifically limited here.

[0163] Combined with Figure 14 and Figure 15 as well as Figure 19 in some embodiments of the present invention, the housing 200 is provided with a sliding groove 230, the guiding member 130 is provided with a toggle rod 134, the toggle rod 134 passes through the sliding groove 230 to extend out of the housing 200, and the toggle rod 134 is toggled to drive the guiding member 130 to move.

[0164] Specifically, the housing 200 is provided with a sliding groove 230, the sliding groove 230 can be configured as an oblong hole extending along the axial direction of the housing 200, the toggle rod 134 passes through the sliding groove 230 and extends out of the housing 200, so as to facilitate the user to drive the toggle rod 134 to slide, and the toggle rod 134 drives the guiding member 130 to move, thereby realizing manually driving the guiding member 130 to move and manually adjusting the working mode of the air type regulating mechanism 100.

[0165] In some embodiments of the present invention, the air type regulating mechanism 100 is detachably connected to the housing 200.

[0166] Specifically, an installation part 240 is arranged in the housing 200, an installation cooperation part 117 is arranged on the bracket 110, and the installation cooperation part 117 can be detachably connected to the installation part 240 so that the air type regulating mechanism 100 is detachably connected to the housing 200.

[0167] Optionally, combined with Figure 10 and Figure 15 the installation part 240 can be configured as a plate structure, similarly, the installation cooperation part 117 can be configured as a plate structure, and a plurality of installation parts 240 and a plurality of installation cooperation parts 117 can be provided. When the air type regulating mechanism 100 is arranged in the housing 200, the plurality of installation parts 240 and the plurality of installation cooperation parts 117 are arranged in one-to-one correspondence, and the threaded connecting piece can pass through the installation part 240 and the installation cooperation part 117 to fixedly connect the installation part 240 and the installation cooperation part 117, so that the air type regulating mechanism 100 can be installed in the housing 200, and this assembly method can realize the detachable connection between the air type regulating mechanism 100 and the housing 200, so as to facilitate the disassembly, assembly or replacement of the air type regulating mechanism 100.

[0168] Optionally, referring to Figure 17 the installation part 240 can be configured as an internal thread, the installation cooperation part 117 can be configured as an external thread, and 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, so as to facilitate the disassembly, assembly or replacement of the air type regulating mechanism 100.

[0169] Optionally, referring to Figure 16, the installation part 240 can be configured as a plug-in slideway, the installation and cooperation part 117 can be configured as a ball head structure extending in the axial direction, and the installation and cooperation part 117 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 is fixed to the housing 200 by rotating, so that the air type adjustment mechanism 100 can be installed in the housing 200, and the air type adjustment mechanism 100 is detachably connected to the housing 200, facilitating the disassembly, installation or replacement of the air type adjustment mechanism 100. When it is necessary to disassemble the air type adjustment mechanism 100 from the housing 200, the air type adjustment mechanism 100 can be rotated in the reverse direction and the ball head structure can be pulled out of the plug-in slideway.

[0170] Optionally, as Figure 18 shown, the installation and cooperation part 117 can be configured as a magnet seat, the installation part 240 can be configured as a mating magnet, and the installation part 240 and the installation and cooperation part 117 can be magnetically mated, so that the air type adjustment mechanism 100 can be installed in the housing 200, and the air type adjustment mechanism 100 is detachably connected to the housing 200, facilitating the disassembly, installation or replacement of the air type adjustment mechanism 100.

[0171] In some other embodiments of the present invention, the air type adjustment mechanism 100 can be pre-processed into two forms, namely a diffused air form and a concentrated air form. The guide vanes 150 of the air type adjustment mechanism 100 in the diffused air form maintain the first state, and the air duct adjustment member 120 maintains the diffused air state; the guide vanes 150 of the air type adjustment mechanism 100 in the concentrated air form maintain the second state, and the air duct adjustment member 120 maintains the concentrated air state. Users can manually replace the air type adjustment structure in different forms according to actual usage requirements. The air type adjustment mechanism 100 of this structure does not need to be provided with a driving structure for driving the guide vanes 150 and the air duct adjustment member 120, effectively simplifying the structure of the air type adjustment mechanism 100, reducing the production and processing cost, and improving the production efficiency.

[0172] In some embodiments of the present invention, the driving fan 300 is an axial flow fan.

[0173] 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 150 assembly is driven to flow towards the guide vane 150 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.

[0174] Further, the guide vane 150 and the air duct adjusting member 120 can play a role in guiding the air flow. Among them, when the guide vane 150 is in the first state, the air duct adjusting member 120 is in the air-diffusing state, and the interference of the guide vane 150 and the air duct adjusting member 120 on the air flow is small. When the air flow flows out of the air flow pattern regulating mechanism 100, it can still maintain a certain circumferential component velocity, so that the air flow flowing out of the air flow pattern regulating mechanism 100 diverges more gently in the radial direction.

[0175] When the guide vane 150 is in the second state, the air duct adjusting member 120 is in the air-concentrating state. After the air flow impinges on the guide vane 150, the guide vane 150 guides the air flow, and the circumferential component velocity of the air flow is converted into an axial component velocity. After flowing through the guide vane 150, the air flow further flows into the air duct adjusting member 120, and the air duct adjusting member 120 further regularizes the air flow flowing into it, so that the air flow flowing out of the air duct adjusting member 120 is more concentrated in the axial direction.

[0176] As Figure 6 shown, in some embodiments of the present invention, the air flow pattern regulating mechanism 100 is the above-mentioned air flow pattern regulating mechanism 100. The cross-section of the guide vane 150 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 blade 310 of the driving fan 300, and the cross-section is perpendicular to the rotation center line of the driving fan 300.

[0177] 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 guide vane 150 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 spiral direction of the Archimedean spiral) is opposite to the rotation direction of the blade 310 of the driving fan 300. The rotation direction of the blade 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 enable the air flow to flow through the guide vane 150 and contact the guide vane 150, and then the air flow can move along the wall surface of the guide vane 150 towards the central axis of the bracket 110, and 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.

[0178] As Figure 7 shown, in some other embodiments of the present invention, the cross-section of the guide vane 150 can be a straight surface to facilitate the processing of the guide vane 150 assembly. The shape of the guide vane 150 can be determined according to the air guiding requirements of the air flow pattern regulating mechanism 100, and no specific limitation is made here.

[0179] 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.

[0180] Specifically, a plurality of blades 310 are arranged in sequence along the axial direction. When driving the fan 300 to operate, the plurality of blades 310 are driven to rotate. During the rotation of the blades 310, the surrounding air flow is driven, thereby forming an air flow with a certain flow velocity.

[0181] 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.

[0182] 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 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 vanes 150, preventing the air flow from diverging inside the fan 1000, and effectively concentrating the air flow.

[0183] 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 tip 311 of the blade 310.

[0184] In the present application, "on the first projection plane, the orthographic projection of the bracket 110 covers the circle where the 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).

[0185] Combined with Figure 1 、 Figure 2 and Figure 21 , in some embodiments of the present invention, a part of the blade 310 of the driving fan 300 extends into the bracket 110.

[0186] Specifically, the dimension of the bracket 110 in the radial direction can be larger than the radial dimension of the circle where the 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 inside 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 vanes 150, and ensure the flow efficiency of the air flow.

[0187] 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 method 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.

[0188] Combined with Figures 20 to 22 In some embodiments of the present invention, the fan 1000 further includes an air outlet grille 400, and the air outlet grille 400 is disposed in the air outlet area 220.

[0189] 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 blade 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 blade 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.

[0190] Referring to Figure 22 In some embodiments of the present invention, the air outlet grille 400 includes an intermediate area 410 and an outer ring area 420. The air guiding rib 430 in the intermediate 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.

[0191] Specifically, the intermediate area 410 and the outer ring area 420 are configured as annular shapes, and the intermediate area 410 and the outer ring area 420 are coaxially arranged. The outer ring area 420 is sleeved on the outside of the intermediate area 410 to achieve a 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.

[0192] 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, when the fan 1000 is in the air-diffusing mode, the air outlet area 220 corresponding to the air outlet 122 of the air duct adjusting member 120 is different from the air outlet area 220 corresponding to the fan 1000 when it 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 intermediate area 410. At the same time, the intermediate area 410 faces the guide vane assembly 140. The intermediate 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 intermediate area 410.

[0193] 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 according to the Archimedes spiral principle. A plurality of arc-shaped ribs 431 are evenly spaced in 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.

[0194] 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 to 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.

[0195] 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 in the axial direction. When the fan 1000 is in the air-diffusing 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 to 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.

[0196] 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.

[0197] 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.

[0198] 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.

[0199] 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°.

[0200] 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.

[0201] In some embodiments of the present invention, the air outlet grille 400 is detachably provided on the housing 200.

[0202] 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 regulating mechanism 100 and improve the maintenance convenience of the fan 1000.

[0203] Among them, the air outlet grille 400 can be detachably connected to the housing 200 by means of screw connection or snap connection, etc. The specific connection manner 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.

[0204] 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.

[0205] 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 regulating mechanism 100, and the air flow regulating 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.
