[0053] In combination with Figures 1-2 and Figures 3-10The wind type regulation mechanism 100 comprises a support 110, a guide ring 130 and a guide vane assembly 140, the guide ring 130 is formed as a ring structure; the guide vane assembly 140 comprises a plurality of first guide vanes 141 and a plurality of second guide vanes 142, the plurality of first guide vanes 141 are arranged on the guide ring 130 in a circumferential direction of the guide ring 130; the plurality of second guide vanes 142 are arranged on the support 110 in a circumferential direction of the support 110; the guide ring 130 is rotatable relative to the support 110 so as to rotate the first guide vanes 141 relative to the second guide vanes 142.

[0054] Specifically, the guide ring 130 is formed as a ring structure, the plurality of first guide vanes 141 are arranged on the guide ring 130 in a circumferential direction of the guide ring 130, a first gap is formed between every two adjacent first guide vanes 141, the first guide vanes 141 can guide the airflow when the airflow flows through the first gap, the support 110 is formed as a ring structure, the plurality of second guide vanes 142 are arranged on the support 110 in a circumferential direction of the support 110, a second gap is formed between every two adjacent second guide vanes 142, the second guide vanes 142 can guide the airflow when the airflow flows into the second gap.

In this way, the guide vane assembly 140 has different states, so that the airflow has different air outlet wind feelings.

[0056] In the related art, a guide mechanism for adjusting the flow direction of air is arranged on the fan, but the working state of the guide mechanism cannot be adjusted, resulting in a single blowing range and air outlet feeling of the fan, which cannot meet the use demand of the user and affects the use experience of the user.

[0057] The first guide vanes 141 and the second guide vanes 142 are correspondingly arranged, the first guide vanes 141 and the second guide vanes 142 can continuously guide the airflow, continuously adjust the airflow, improve the flow regulation effect of the guide vane assembly 140 on the airflow, and make the airflow in a converging state when flowing out of the guide vane assembly 140, so that the air type regulation mechanism 100 has different air outlet states and air outlet effects, the air type regulation mechanism 100 has different working states, the user can adjust the working state of the air type regulation mechanism 100 according to the actual demand, the use demand of the user is met, and meanwhile, the air type regulation mechanism 100 has a simple structure, which is favorable for reducing the production cost of the air type regulation mechanism 100 and improving the production efficiency.

[0058] The first guide vanes 141 and the second guide vanes 142 are correspondingly arranged, the first guide vanes 141 and the second guide vanes 142 can continuously guide the airflow, continuously adjust the airflow, improve the flow regulation effect of the guide vane assembly 140 on the airflow, and make the airflow in a converging state when flowing out of the guide vane assembly 140, so that the air type regulation mechanism 100 has different air outlet states and air outlet effects, the air type regulation mechanism 100 has different working states, the user can adjust the working state of the air type regulation mechanism 100 according to the actual demand, the use demand of the user is met, and meanwhile, the air type regulation mechanism 100 has a simple structure, which is favorable for reducing the production cost of the air type regulation mechanism 100 and improving the production efficiency.

[0059] It should be noted that the shape of the guide ring 130 can be configured as a polygonal shape or a circular ring shape, and the specific shape of the guide ring 130 is not limited here, as long as the guide ring 130 can rotate relative to the support 110.

[0060] In combination Figures 1 to 8 In some embodiments of the present application, the air duct adjusting piece 120 includes a plurality of adjusting pieces 121, and the plurality of adjusting pieces 121 are arranged along the circumferential direction of the support 110. Each adjusting piece 121 is rotatably arranged on the support 110 so that the air duct adjusting piece 120 can be switched between different states.

[0061] Specifically, the plurality of adjusting pieces 121 are uniformly and evenly arranged along the circumferential direction of the support 110, and the adjusting piece 121 is rotatably connected to the support 110. For example, the adjusting piece 121 can rotate relative to the center of the support 110, and the air type regulation mechanism 100 is provided with a guide ring 130. When the guide ring 130 rotates relative to the support 110, the guide ring 130 drives the adjusting piece 121 to rotate synchronously relative to the support 110.

[0062] Further, the air duct adjusting piece 120 includes a plurality of adjusting pieces 121, and the adjusting piece 121 can guide the airflow. The adjusting piece 121 can have different rotating angles relative to the support 110, so that the air duct adjusting piece 120 has different states, so that the air duct adjusting piece 120 can have different guiding effects on the airflow, and the airflow out of the air duct adjusting piece 120 can be adjusted.

[0063] In combination Figure 1 And Figure 9 The guide ring 130 rotates to drive the plurality of adjusting pieces 121 to rotate synchronously in the forward direction relative to the support 110. At this time, the air outlet end of the adjusting piece 121 rotates relative to the air inlet end to the direction of the extension line of the center axis of the support 110, so that the air outlet 122 of the air duct adjusting piece 120 formed by the plurality of adjusting pieces 121 is reduced in the direction away from the extension line of the center axis of the support 110. The area of the air outlet 122 of the air duct adjusting piece 120 is reduced, and the air duct adjusting piece 120 realizes the air gathering state. The guide ring 130 rotates to drive the plurality of adjusting pieces 121 to rotate synchronously in the reverse direction relative to the support 110. At this time, the air outlet end of the adjusting piece 121 rotates relative to the air inlet end to the direction away from the extension line of the center axis of the support 110, so that the air outlet 122 of the air duct adjusting piece 120 formed by the plurality of adjusting pieces 121 is expanded in the direction away from the extension line of the center axis of the support 110. The area of the air outlet 122 of the air duct adjusting piece 120 is increased, and the air duct adjusting piece 120 realizes the air dispersion state.

[0064] It should be noted that the "air inlet end" refers to one end of a component such as the guide ring 130, the support 110 or the air duct adjusting piece 120, through which air flows from the outside, and the "air outlet end" refers to one end of the component such as the guide ring 130, the support 110 or the air duct adjusting piece 120, through which air flows from the inside, and the air inlet end of the air duct adjusting piece 120 is the air inlet end of the adjusting piece 121, and similarly, the air outlet end of the air duct adjusting piece 120 is the air outlet end of the adjusting piece 121.

[0065] The guide ring 130 is connected with the plurality of adjusting pieces 121 to drive the plurality of adjusting pieces 121 to rotate synchronously, and the guide ring 130 rotates relative to the support 110 to make the plurality of first guide vanes 141 rotate relative to the second guide vanes 142 and the plurality of adjusting pieces 121 swing synchronously, so that different states of the air duct adjusting piece 120 and different states of the guide vane assembly 140 are combined with each other, and the air type adjusting mechanism 100 has different air outlet states and air outlet effects. Therefore, the guide vane assembly 140 can be switched between the first state and the second state, and the air duct adjusting piece 120 can be switched between the air diffusion state and the air gathering state, so as to realize adjustment of the working mode of the air type adjusting mechanism 100.

[0066] It can be seen that the guide ring 130 is rotatable relative to the support 110 to make the plurality of first guide vanes 141 rotate relative to the second guide vanes 142 and the plurality of adjusting pieces 121 swing synchronously, so that different states of the air duct adjusting piece 120 and different states of the guide vane assembly 140 are combined with each other, and the air type adjusting mechanism 100 has different air outlet states and air outlet effects, so that the air type adjusting mechanism 100 has different working states, and the user can adjust the working state of the air type adjusting mechanism 100 according to actual needs to meet the use needs of the user.

[0067] In some embodiments of the present application, the guide ring 130 is integrally formed with the plurality of first guide vanes 141.

[0068] Specifically, the guide ring 130 is integrally formed with the plurality of first guide vanes 141, which can improve the structural strength of the guide ring 130 and the plurality of first guide vanes 141, and ensure the stability of the guide ring 130 and the plurality of first guide vanes 141 as a whole.

[0069] Alternatively, the guide ring 130 and the plurality of first guide vanes 141 are separate parts. For example, the plurality of first guide vanes 141 are detachably assembled on the guide ring 130.

[0070] In combination Figures 1 to 8 In some embodiments of the present application, the middle part of the support 110 is provided with a mounting seat 120, and the guide vane assembly 140 further includes a plurality of second guide vanes 142, and the plurality of second guide vanes 142 are arranged at intervals along the circumference of the support 110, and the two ends of each second guide vane 142 are connected with the support 110 and the mounting seat 120, respectively;

[0071] Specifically, in combination Figures 7 to 8 The mounting space is formed in the bracket 110, the mounting seat 120 is arranged in the mounting space, the mounting seat 120 and the bracket 110 jointly define a ring-shaped assembly space, the plurality of second guide vanes 142 are arranged in the ring-shaped assembly space, and the plurality of second guide vanes 142 are arranged at intervals in the circumferential direction of the bracket 110, a second gap is formed between every two adjacent second guide vanes 142, the second guide vanes 142 can guide the airflow when the airflow flows into the second gap, and the two ends of each second guide vane 142 are fixedly connected with the mounting seat 120 and the bracket 110, so that the assembly reliability of the second guide vanes 142 is ensured.

[0072] In combination Figures 1 to 2 In some embodiments of the utility model, the middle part of the guide ring 130 is provided with a support seat 137, the guide vane assembly 140 further comprises a plurality of first guide vanes 141, the plurality of first guide vanes 141 are arranged at intervals in the circumferential direction of the guide ring 130, and the two ends of each first guide vane 141 are connected with the guide ring 130 and the support seat 137 respectively;

[0073] Specifically, in combination Figures 1 to 2 The support seat 137 can be arranged in the guide ring 130, the support seat 137 and the guide ring 130 jointly define a ring-shaped arrangement space, the plurality of first guide vanes 141 are arranged in the ring-shaped arrangement space and connected with the guide ring 130 and the support seat 137 respectively, so as to facilitate the assembly of the first guide vanes 141, and the plurality of first guide vanes 141 are connected with the guide ring 130, so that the guide ring 130 can drive the plurality of first guide vanes 141 to rotate synchronously.

[0074] In combination Figure 2 In some embodiments of the utility model, the guide ring 130 rotates to switch the guide vane assembly 140 between the first state and the second state, in the first state, the plurality of first guide vanes 141 and the plurality of second guide vanes 142 are arranged at intervals in the circumferential direction, and in the second state, the plurality of first guide vanes 141 and the plurality of second guide vanes 142 are arranged in one-to-one correspondence in the front-back direction.

[0075] Specifically, the airflow adjusting piece has a first state and a second state, the plurality of first guide vanes 141 and the plurality of second guide vanes 142 can move relative to each other, so as to switch the airflow adjusting piece between the first state and the second state, in combination Figure 2In the first state, the first guide vanes 141 and the second guide vanes 142 are arranged one by one in the direction of the central axis of the support 110, and the first gaps and the second gaps are opposite to each other at this time. The airflow flows into the second gaps, and the second guide vanes 142 guide the airflow, and then the airflow continues to flow into the first gaps, so that the first gaps further guide the airflow. The circumferential component velocity of the airflow is converted into the axial component velocity, so that the airflow can be concentrated to the central axis of the support 110. The first gaps and the second gaps form a continuous flow space, and the first guide vanes 141 and the second guide vanes 142 can continuously guide the airflow to continuously adjust the airflow. The airflow adjusting member improves the flow effect of the airflow, improves the effect of converting the circumferential component velocity of the airflow into the axial component velocity, reduces the flow area of the airflow in the radial direction when the airflow flows out of the airflow adjusting member, so that the airflow after flowing out is in a cylindrical shape, and the axial velocity of the airflow when flowing out is large, so that the air outlet intensity is large.

[0076] It should be noted that the airflow flowing through the airflow type control mechanism 100 is spiral, which has a circumferential component velocity and an axial component velocity.

[0077] Further, in combination with Figure 7 and Figure 8 In the second state, the orthographic projection of each second guide vane 142 is located between the orthographic projections of every two adjacent first guide vanes 141 in the direction of the central axis of the support 110, that is, the second guide vanes 142 are arranged opposite to the first gaps in the axial direction, so that the first guide vanes 141 and the second guide vanes 142 are arranged in the circumferential direction. The first gaps and the second gaps are arranged in a staggered manner, and the first guide vanes 141 and the second guide vanes 142 cannot continuously guide the airflow. Compared with the first state, the second guide vanes 142 guide the airflow for a short time when the airflow flows into the second gaps. Similarly, the first guide vanes 141 guide the airflow for a short time when the airflow flows into the first gaps. The flow effect of the airflow adjusting member on the airflow is reduced as a whole, and the airflow can maintain the circumferential component velocity when flowing through the airflow adjusting member, so that the airflow after flowing out is in a conical shape, and the divergence state of the airflow when flowing out is ensured.

[0078] It can be seen that the airflow adjusting piece is provided with the first guide vane 141 and the second guide vane 142, in the first state, the first guide vane 141 and the second guide vane 142 are oppositely arranged in the front-rear direction, the first guide vane 141 and the second guide vane 142 can continuously guide the airflow, the guiding effect of the airflow adjusting piece on the airflow is improved, the effect that the circumferential component velocity of the airflow is converted into the axial component velocity is improved, the flow area of the airflow in the radial direction when the airflow flows out of the airflow adjusting piece is reduced, and the axial velocity of the airflow when the airflow flows out is large, the airflow is in a converging state when the airflow flows out, and the air outlet intensity of the airflow is large; in the second state, the airflow adjusting piece has a small flow regulating effect on the airflow, and the circumferential component velocity of the airflow can be maintained when the airflow flows through the airflow adjusting piece, so that the airflow can be in a conical shape when the airflow flows out of the airflow adjusting piece, and the divergence state of the airflow when the airflow flows out is ensured, thereby, the air type regulation mechanism 100 adjusts the air outlet range and the air outlet intensity of the airflow, and the working state of the air type regulation mechanism 100 can be switched, the user can adjust the working state of the air type regulation mechanism 100 according to the actual use demand, so as to meet the different use demands of the user, and the structure of the air type regulation mechanism 100 is simple, which is beneficial to reduce the production cost of the air type regulation mechanism 100 and improve the production efficiency.

[0079] In combination Figure 4 And Figure 5 In some embodiments of the present application, one of the first guide vane 141 and the second guide vane 142 located upstream of the airflow is provided with a first guide surface 140a, and the first guide surface 140a is used to guide the airflow towards the end surface of the other one.

[0080] Specifically, the first guide surface 140a can reduce the resistance of one of the first guide vane 141 and the second guide vane 142 located upstream of the airflow to the airflow, so that the airflow passage is more smooth.

[0081] For example, the first guide vane 141 is located on the upstream side of the second guide vane 142, and the first guide surface 140a is arranged on both sides of the thickness of the first guide vane 141, so as to guide the airflow by the first guide surface 140a of the first guide vane 141, reduce the resistance of the first guide vane 141 to the airflow, make the airflow pass through the first guide vane 141 more smoothly, and guide the airflow to the end surface of the second guide vane 142 by the first guide surface.

[0082] It can be understood that one of the first guide vane 141 and the second guide vane 142 located upstream of the airflow is designed as a transition, for example, as a chamfered design, which is beneficial to reduce the influence on the airflow, make the airflow flowing through the guide vane assembly 140 more smooth, and reduce noise.

[0083] In combination Figure 4 And Figure 5In some embodiments of the utility model, another of first guide blade 141 and second guide blade 142 located downstream of airflow is provided with second guide surface 140b, and second guide surface 140b is used to guide airflow towards the air outlet side of support 110.

[0084] Specifically, second guide surface 140b can guide the airflow flowing to second guide surface 140b more smoothly, which is conducive to reducing noise and vortex and ensuring the smooth airflow on the air outlet side.

[0085] For example, in combination with Figures 4-5 Second guide blade 142 is located on the downstream side of first guide blade 141, and second guide surface 140b of second guide blade 142 and first guide surface 140a of first guide blade 141 are smoothly connected, which is conducive to ensuring the smooth and smooth flow of airflow from first guide blade 141 to second guide blade 142.

[0086] For example, in combination with Figure 5 In some embodiments of the utility model, the distance between first guide blade 141 and second guide blade 142 is less than 3mm.

[0087] Specifically, under the premise of ensuring that first guide blade 141 and second guide blade 142 do not collide, the smaller the gap between first guide blade 141 and second guide blade 142, the better, so as to prevent the airflow from escaping from the gap between first guide blade 141 and second guide blade 142, and to ensure the wind gathering effect of the airflow adjusting piece. For example, in combination with Figure 5 The distance between first guide blade 141 and second guide blade 142 is S.

[0088] Further, the distance between first guide blade 141 and second guide blade 142 is less than or equal to 1.6mm, so that the gap between first guide blade 141 and second guide blade 142 is appropriate, so as to prevent the airflow from escaping from the gap between first guide blade 141 and second guide blade 142, and at the same time, first guide blade 141 and second guide blade 142 have appropriate assembly precision, which is conducive to reducing assembly difficulty.

[0089] Preferably, the distance between first guide blade 141 and second guide blade 142 is 0.5mm, so as to prevent the airflow from escaping from the gap between first guide blade 141 and second guide blade 142, and at the same time, the relative movement between first guide blade 141 and second guide blade 142 can be effectively prevented from colliding, ensuring the normal operation of the airflow adjusting piece.

[0090] For example, in combination with Figure 1In some embodiments of the utility model, multiple adjusting pieces 121 are arranged along the circumference of support 110, each adjusting piece 121 is provided with a rotating part 1211 and a guiding part 1212, the rotating part 1211 is rotatably arranged on support 110; guiding ring 130 is provided with multiple first guiding grooves 131, the guiding part 1212 of multiple adjusting pieces 121 is arranged one-to-one with multiple first guiding grooves 131, each guiding part 1212 is slidingly matched with the corresponding first guiding groove 131, guiding ring 130 rotates to drive multiple adjusting pieces 121 to rotate synchronously.

[0091] Specifically, multiple adjusting pieces 121 are evenly spaced along the circumferential direction of support 110, the adjusting piece 121 is provided with a rotating part 1211 and a guiding part 1212, the adjusting piece 121 is rotatably connected with the support 110 through the rotating part 1211, and the air type regulation mechanism 100 is provided with a guiding ring 130, when the guiding ring 130 rotates relative to the support 110, the guiding ring 130 can drive the adjusting piece 121 to rotate synchronously relative to the support 110 through the guiding part 1212.

[0092] Further, the guiding part 1212 of the adjusting piece 121 is slidingly matched with the first guiding groove 131 on the guiding ring 130, when the guiding ring 130 rotates relative to the support 110, the guiding ring 130 drives the first guiding groove 131 to rotate synchronously, the guiding part 1212 slides relative to the first guiding groove 131, and the first guiding groove 131 can drive the adjusting piece 121 to rotate relative to the support 110 through the guiding part 1212.

[0093] For example, in combination with Figure 1 , Figure 6 and Figure 9 , the first guiding groove 131 can be configured as a groove structure extending obliquely on the guiding ring 130, that is, one end of the first guiding groove 131 is arranged close to the air outlet end of the guiding ring 130, and the other end of the first guiding groove 131 is arranged close to the air inlet end of the guiding ring 130, when the guiding ring 130 rotates, since the first guiding groove 131 extends obliquely, when the guiding part 1212 slides relative to the first guiding groove 131, the first guiding groove 131 can drive the guiding part 1212 to rotate, the guiding part 1212 can drive the rotating part 1211 and the adjusting piece 121 to rotate relative to the support 110, thereby realizing that the guiding ring 130 drives multiple adjusting pieces 121 to rotate synchronously, of course, it can be understood that the arrangement mode of the first guiding groove 131 is not limited to this, as long as the first guiding groove 131 can drive the adjusting piece 121 to rotate synchronously through the driving part when the guiding ring 130 rotates.

[0094] By rotating the adjusting piece 121 relative to the support 110 to adjust the rotation angle of the adjusting piece 121 relative to the support 110, the air duct adjusting piece 120 can be switched between different states, and the guide ring 130 is rotatable relative to the support 110 to rotate the plurality of first guide vanes 141 relative to the second guide vanes 142, so that the guide vane assembly 140 can be switched between different states, thereby adjusting the air outlet range and air feeling of the airflow flowing out of the air type regulation mechanism 100 to meet different use requirements of the user and improve the use experience of the user.

[0095] Further, the rotating part 1211 is fixedly connected with the adjusting piece 121, so that the rotating part 1211 can drive the adjusting piece 121 to rotate relative to the support 110, so as to adjust the opening area of the air duct adjusting piece 120, thereby adjusting the working mode of the air duct adjusting piece 120.

[0096] It should be noted that when the guide ring 130 is rotated to make the first guide vane 141 and the second guide vane 142 misaligned, the first guide groove 131 drives the guide part 1212 to move in a direction parallel to the central axis of the guide ring 130 and away from the air duct adjusting piece 120, so that the guide part 1212 moves away from the air duct adjusting piece 120, the guide part 1212 drives the adjusting piece 121 to rotate through the rotating part 1211, and the air outlet end of the adjusting piece 121 moves away from the central axis of the air duct adjusting piece 120, so that the air outlet 122 of the air duct adjusting piece 120 expands, the area of the air outlet 122 of the air duct adjusting piece 120 increases, and at this time the guide vane assembly 140 is in the first state, the air duct adjusting piece 120 is in the air diffusion state, and the air type regulation mechanism 100 is in the air diffusion mode.

[0097] When the guide ring 130 is rotated to make the first guide vane 141 and the second guide vane 142 opposite to each other, the first guide groove 131 drives the guide part 1212 to move in a direction parallel to the central axis of the guide ring 130 and close to the air duct adjusting piece 120, so that the guide part 1212 moves close to the air duct adjusting piece 120, the guide part 1212 drives the adjusting piece 121 to rotate through the rotating part 1211, and the air outlet end of the adjusting piece 121 moves close to the central axis of the air duct adjusting piece 120, so that the air outlet 122 of the air duct adjusting piece 120 shrinks, the area of the air outlet 122 of the air duct adjusting piece 120 decreases, and at this time the guide vane assembly 140 is in the second state, the air duct adjusting piece 120 is in the air concentration state, and the air type regulation mechanism 100 is in the air concentration mode.

[0099] Specifically, when the air duct adjusting piece 120 is adjusted to the air diffusing state, the air duct adjusting piece 120 in the air diffusing state has a larger air outlet 122 area, the plurality of adjusting pieces 121 expand around the air outlet 122 of the formed air duct adjusting piece 120 in a direction away from the extension line of the central axis of the support 110, the interference of the adjusting pieces 121 to the circumferential component velocity of the airflow is small, and the airflow can still maintain a certain circumferential component velocity when being discharged from the air duct adjusting piece 120, so that the air outlet area is large, the air outlet is soft, and the air diffusing state of the air duct adjusting piece 120 is realized. When the air duct adjusting piece 120 is adjusted to the air concentrating state, the air duct adjusting piece 120 in the air concentrating state has a smaller air outlet 122 area, the plurality of adjusting pieces 121 shrink around the air outlet 122 of the formed air duct adjusting piece 120 in a direction close to the extension line of the central axis of the support 110, the interference of the adjusting pieces 121 to the circumferential component velocity of the airflow is large, and the circumferential component velocity of the airflow is small when being discharged from the air duct adjusting piece 120, so that the air outlet area is small, the air outlet is concentrated, and the air concentrating state of the air duct adjusting piece 120 is realized.
