[0002] This application claims the priority of a Chinese patent application with the application number "202311874241.4" and the title "Wind Type Regulation Mechanism and Fan", which was filed by Guangdong Midea Environmental Appliance Manufacturing Co., Ltd. on December 29, 2023. Technical field

[0003] The present invention relates to the technical field of household appliances, and in particular, to a wind type regulation mechanism and a fan. Background art

[0004] With the increasing living standards of people, consumers have higher and higher requirements for fans.

[0005] In related technologies, a guiding mechanism for adjusting the air flow direction is provided on the fan. However, the working state of the guiding mechanism cannot be adjusted, resulting in a single blowing range and air outlet feeling of the fan, which cannot meet the user's usage requirements. At the same time, the structure of the guiding mechanism is complex, resulting in high production costs and low processing efficiency of the fan. Summary of the invention

[0006] The present invention aims to solve at least one of the technical problems existing in the prior art. For this purpose, the present invention provides a wind type regulation mechanism, the working state of which can be adjusted, so as to realize the adjustment of the air outlet feeling and the air outlet range. At the same time, the structure of the wind type regulation mechanism is simple and convenient for production and processing.

[0007] A wind type regulation mechanism includes: a bracket provided with an annular air duct space; an air flow regulator disposed in the air duct space, the air flow regulator including multiple layers of guide vanes arranged in the front - rear direction, the multiple layers of guide vanes including a plurality of front - side guide vanes and a plurality of rear - side guide vanes, the plurality of front - side guide vanes being located in front of the air outlet of the plurality of rear - side guide vanes and being relatively rotatable, the plurality of front - side guide vanes being circumferentially spaced apart, the plurality of rear - side guide vanes being circumferentially spaced apart, the air flow regulator having a first state and a second state. In the first state, at least part of the plurality of front - side guide vanes and the plurality of rear - side guide vanes overlap in the front - rear direction. In the second state, the plurality of front - side guide vanes and the plurality of rear - side guide vanes are misaligned in the circumferential direction.

[0008] According to the wind type control mechanism of the present invention, by providing an air flow regulating member, the wind type control mechanism can adjust the air outlet range and air outlet intensity. When the air flow regulating member is in the first state, the front guide vane and the rear guide vane are arranged opposite to each other in the front-rear direction. The front guide vane and the rear guide vane can continuously guide the air flow, and the circumferential component velocity of the air flow is converted into the axial component velocity. When the air flow flows out, it is in a converging state, and the air outlet intensity of the air flow is large. In the second state, the air flow regulating member has a small rectifying effect on the air flow. When the air flow passes through the air flow regulating member, the circumferential component velocity of the air flow can be maintained, so that the air flow can be in a conical shape when flowing out of the air flow regulating member, ensuring the divergent state when the air flow flows out. Moreover, the air flow regulating member can be switched between the first state and the second state, so that the wind type control mechanism has different working states. Users can adjust the working state of the wind type control mechanism according to actual needs to meet the user's usage requirements. At the same time, the structure of the wind type control mechanism of the present application is simple, which is beneficial to reducing the production cost of the wind type control mechanism and improving the production efficiency.

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 situations.

[0065] Reference is made below Figures 1 - 19 to describe the air pattern regulation mechanism 100 and the fan 1000 according to embodiments of the present invention.

[0066] In combination with Figures 1 to 4 , according to the air pattern regulation mechanism 100 of the present invention, it includes: a bracket 110 and an air flow regulating member 120. The bracket 110 is provided with an annular air duct space 111, and the air flow regulating member 120 is disposed in the air duct space 111. The air flow regulating member 120 includes multiple layers of guide vanes 1201 arranged in the front-rear direction. The multiple layers of guide vanes 1201 include a plurality of front guide vanes 121 and a plurality of rear guide vanes 122. The plurality of front guide vanes 121 are located on the air outlet front side of the plurality of rear guide vanes 122 and are relatively rotatable. The plurality of front guide vanes 121 are circumferentially spaced apart, and the plurality of rear guide vanes 122 are circumferentially spaced apart. The air flow regulating member 120 has a first state and a second state. In the first state, the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are at least partially overlapped in the front-rear direction. In the second state, the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are circumferentially offset.

[0067] It should be noted that the multiple layers of guide vanes 1201 are at least two layers of guide vanes 1201, that is, the multiple layers of guide vanes 1201 can be two layers of guide vanes 1201, three layers of guide vanes 1201, or four layers of guide vanes 1201, etc. arranged in the front-rear direction. It also needs to be explained that each layer of guide vanes includes a plurality of guide vanes circumferentially spaced apart, that is, the plurality of front guide vanes 121 are located in the same layer, and the plurality of rear guide vanes 122 are located in the same layer.

[0068] Specifically, the bracket 110 can provide an installation position for the air flow regulating member 120. Among them, the bracket 110 is provided with an annular air duct space 111. A plurality of front guide vanes 121 are arranged at intervals in the circumferential direction in sequence. A front gap is formed between every two adjacent front guide vanes 121 for air flow to pass through. A plurality of rear guide vanes 122 are arranged at intervals in the circumferential direction in sequence. A rear gap is formed between every two adjacent rear guide vanes 122 for air flow to pass through. And the front guide vanes 121 and the rear guide vanes 122 are arranged in the air duct space 111 in the axial direction. The front guide vanes 121 are located at the air outlet end of the rear guide vanes 122. The air flow flows through the rear guide vanes 122 from the air inlet end of the rear guide vanes 122 and flows through the air outlet end of the rear guide vanes 122 into the gap between the plurality of front guide vanes 121. Both the rear guide vanes 122 and the front guide vanes 121 can play a role in guiding the air flow, so as to play a role in adjusting the flow direction of the air flow.

[0069] Furthermore, the air flow regulating member 120 has a first state and a second state. Relative movement can occur between the plurality of front guide vanes 121 and the plurality of rear guide vanes 122, so as to facilitate the switching of the air flow regulating member 120 between the first state and the second state. Combining Figure 1 and Figure 2 , in the first state, in the direction of the central axis extension of the air duct space 111, the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged in one-to-one correspondence, and at least part of the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 overlap, that is, at least part of the orthographic projection of the plurality of front guide vanes 121 in the central axis direction of the air duct space 111 overlaps with the orthographic projection of the plurality of rear guide vanes 122 in the central axis direction of the air duct space 111. For example: the end portions of the plurality of front guide vanes 121 in the direction of the central axis extension of the air duct space 111 can overlap with the end portions of the plurality of rear guide vanes 122 in the direction of the central axis extension of the air duct space 111, or the plurality of front guide vanes 121 and the plurality of rear guide vanes 122 are arranged in one-to-one facing.

[0070] When multiple front guide vanes 121 and multiple rear guide vanes 122 are arranged in a one-to-one facing manner, the front gap and the rear gap are in alignment. The air flow enters the rear gap, and the rear guide vanes 122 direct the air flow. Then the air flow continues to enter the front gap, where the front gap further directs the air flow. The circumferential component velocity of the air flow is converted into the axial component velocity, enabling the air flow to concentrate towards the central axis of the air duct space 111. The front gap and the rear gap form a continuous flow space, and the front guide vanes 121 and the rear guide vanes 122 can continuously direct the air flow to continuously adjust the air flow, improving the rectifying effect of the air flow regulating member 120 on the air flow, enhancing the effect of converting the circumferential component velocity of the air flow into the axial component velocity, reducing the flow area of the air flow in the radial direction when the air flow flows out of the air flow regulating member 120, making the overall air flow present a cylindrical shape after flowing out, and having a large axial velocity when the air flow flows out, resulting in a large air outlet intensity.

[0071] It should be noted that the air flow passing through the air flow pattern regulating mechanism 100 is spiral, having a circumferential component velocity and an axial component velocity.

[0072] Further combined with Figure 3 and Figure 4 , in the second state, in the extending direction of the central axis of the air duct space 111, the orthographic projection of each rear guide vane 122 is located between the orthographic projections of every two adjacent front guide vanes 121, that is, the rear guide vanes 122 are arranged opposite to the front gap in the axial direction, thereby achieving the staggered arrangement of the multiple front guide vanes 121 and the multiple rear guide vanes 122 in the circumferential direction, and the front gap and the rear gap are staggered. The front guide vanes 121 and the rear guide vanes 122 cannot continuously direct the air flow. Compared with the first state, when the air flow enters the rear gap, the guiding time of the rear guide vanes 122 for the air flow is short. Similarly, when the air flow enters the front gap, the guiding time of the front guide vanes 121 for the air flow is short. The overall rectifying effect of the air flow regulating member 120 on the air flow is reduced. The air flow can maintain the circumferential component velocity when passing through the air flow regulating member 120, making the overall air flow present a conical shape when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow when flowing out.

[0073] It should be noted that the dimension of the front gap in the direction parallel to the central axis of the air duct space 111 is the length dimension of the front gap, and the dimension of the rear gap in the direction parallel to the central axis of the air duct space 111 is the length dimension of the rear gap.

[0074] In the related art, a guiding mechanism for adjusting the air flow direction is provided on the fan. However, the working state of the guiding mechanism cannot be adjusted, resulting in the inability to adjust the blowing range and the air outlet feeling of the fan, unable to meet the user's usage requirements, and affecting the user's usage experience.

[0075] In this application, by providing an air flow regulating member 120 which is provided with a front guide vane 121 and a rear guide vane 122, in the first state, the front guide vane 121 and the rear guide vane 122 are oppositely arranged in the front-rear direction. The front guide vane 121 and the rear guide vane 122 can continuously guide the air flow, improving the guiding effect of the air flow regulating member 120 on the air flow, enhancing the effect of converting the circumferential component velocity of the air flow into the axial component velocity, reducing the flow area of the air flow in the radial direction when flowing out of the air flow regulating member 120, and making the axial velocity of the air flow large when flowing out, with the air flow being in a converging state when flowing out and having a large air outlet intensity. In the second state, the air flow regulating member 120 has a small rectifying effect on the air flow, and the air flow can maintain its circumferential component velocity when flowing through the air flow regulating member 120, causing the air flow to be conical when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow when flowing out. Thus, the air outlet range and the air outlet intensity of the air flow can be adjusted by the air flow regulating mechanism 100, and the working state of the air flow regulating mechanism 100 can be switched. The user can adjust the working state of the air flow regulating mechanism 100 according to actual usage requirements to meet different usage needs of the user. At the same time, the structure of the air flow regulating mechanism 100 of this application is simple, which is beneficial to reducing the production cost of the air flow regulating mechanism 100 and improving the production efficiency.

[0076] According to the air flow regulating mechanism 100 of the present invention, by providing the air flow regulating member 120, the air flow regulating mechanism 100 can adjust the air outlet range and the air outlet intensity. When the air flow regulating member 120 is in the first state, the front guide vane 121 and the rear guide vane 122 are oppositely arranged in the front-rear direction. The front guide vane 121 and the rear guide vane 122 can continuously guide the air flow, converting the circumferential component velocity of the air flow into the axial component velocity, with the air flow being in a converging state when flowing out and having a large air outlet intensity. In the second state, the air flow regulating member 120 has a small rectifying effect on the air flow, and the air flow can maintain its circumferential component velocity when flowing through the air flow regulating member 120, causing the air flow to be conical when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow when flowing out. Moreover, the air flow regulating member 120 can be switched between the first state and the second state, enabling the air flow regulating mechanism 100 to have different working states. The user can adjust the working state of the air flow regulating mechanism 100 according to actual needs to meet the usage needs of the user. At the same time, the structure of the air flow regulating mechanism 100 of this application is simple, which is beneficial to reducing the production cost of the air flow regulating mechanism 100 and improving the production efficiency.

[0077] Combined Figure 5 and Figure 6 , through the simulation analysis of the air flow regulating mechanism 100 of this application, referring to Figure 5 B in Figure 6As shown in D, in the first state, at the standard test distance, the air outlet range of the air type control mechanism 100 is 0.13 ㎡, and the average air velocity within the air outlet range is 2.02 m / s. Refer to Figure 5 as shown in A and Figure 6 as shown in C, in the second state, at the standard test distance, the air outlet range of the air type control mechanism 100 is 0.23 ㎡, and the average air velocity within the air outlet range is 1.36 m / s.

[0078] It should be noted that the air outlet range refers to the area where the air velocity is greater than 0.4 m / s. The "standard test distance" can be the distance three times the diameter of the circle where multiple blade tips 311 are located, so as to facilitate the simulation and test comparison of the air type control mechanism 100.

[0079] Of course, it can be understood that when simulating and testing the air type control mechanism 100 for comparison, it is not limited to measuring at the above "standard test distance", as long as it is ensured that the air outlet effects of the air type control mechanism 100 in the first state and the second state are measured at the same position.

[0080] Combined with Figure 5 and Figure 6 and based on the above data, it can be seen that when the air type control mechanism 100 is in the first state, the air outlet range of the air type control mechanism 100 is small, the air velocity is high, and the air outlet is strong. When the air type control mechanism 100 is in the second state, the air outlet range of the air type control mechanism 100 is large, the air velocity is low, and the air outlet is gentle. Moreover, there are obvious differences in the air outlet feelings of the air type control mechanism 100 in different states, improving the user experience.

[0081] Combined with Figures 1 to 4 and Figure 19 , in some embodiments of the present invention, in the direction parallel to the first central axis, a gap S is formed between the front guide vane 121 and the rear guide vane 122, and S < 3 mm. Further, a gap S is formed between the front guide vane 121 and the rear guide vane 122, and S ≤ 1.6 mm.

[0082] Specifically, on the premise of ensuring that the front guide vane 121 and the rear guide vane 122 do not collide, the smaller the gap between the front guide vane 121 and the rear guide vane 122, the better, so as to prevent the air flow from escaping from the gap between the front guide vane 121 and the rear guide vane 122, which is beneficial to ensuring the wind gathering effect of the air flow regulating member 120.

[0083] Preferably, S is 0.5 mm, so as to prevent the air flow from escaping from the gap between the front guide vane 121 and the rear guide vane 122, and at the same time, it can effectively prevent the front guide vane 121 and the rear guide vane 122 from colliding during relative movement, ensuring the normal operation of the air flow regulating member 120.

[0084] Combined withFigures 1 to 4 and Figure 19 In some embodiments of the present invention, in a direction parallel to the first central axis, a guiding angle 1204 is provided at one end where the front guide vane 121 and the rear guide vane 122 are oppositely arranged relative to each other.

[0085] Specifically, in a direction extending from the front guide vane 121 to the rear guide vane 122, the cross-sectional area of one end of the front guide vane 121 close to the rear guide vane 122 gradually decreases. Similarly, in a direction extending from the rear guide vane 122 to the front guide vane 121, the cross-sectional area of one end of the rear guide vane 122 close to the front guide vane 121 gradually decreases, so that a guiding angle 1204 is formed at one end where the front guide vane 121 and the rear guide vane 122 are oppositely arranged. By providing the guiding angle 1204, the smoothness of the airflow flowing in the airflow regulating member 120 can be effectively improved, and it is beneficial to reduce the noise generated by the airflow.

[0086] Combined with Figures 1 to 4 According to the air pattern regulating mechanism 100 of the present invention, it includes: a duct 101 having an air inlet side and an air outlet side, and the duct 101 restricts the airflow to blow from the air inlet side to the air outlet side; an airflow regulating member 120, which is arranged in the duct 101, for example, at the air outlet of the duct 101. The airflow regulating member 120 has a first central axis, and the airflow regulating member 120 includes a plurality of guide vanes 1201 arranged at intervals around the first central axis. The airflow regulating member 120 has a first state and a second state. In the first state, a first airflow passage pore 1202 is defined between adjacent guide vanes 1201, and in the second state, a second airflow passage pore 1203 is defined between adjacent guide vanes 1201. In a direction parallel to the first central axis, the length of the first airflow passage pore 1202 is greater than the length of the second airflow passage pore 1203.

[0087] Specifically, the air pattern regulating mechanism 100 is provided with a duct 101, and the airflow can flow from the air inlet side of the duct 101 to the air outlet side of the duct 101. The duct 101 can restrict the flow direction of the airflow, prevent the airflow from diverging, and ensure the air outlet effect of the air pattern regulating mechanism 100.

[0088] Furthermore, the airflow regulating member 120 is arranged in the duct 101 to guide the airflow flowing into the duct 101. Among them, the airflow regulating member 120 includes a plurality of guide vanes 1201, and the plurality of guide vanes 1201 extend radially outward around the first central axis, and a gap is formed between every two adjacent guide vanes 1201. The airflow can flow through the gap between two adjacent guide vanes 1201 to flow through the guide vanes 1201, so that the guide vanes 1201 can guide the airflow to convert the circumferential component velocity into the axial component velocity, and the airflow can flow in a direction close to the first central axis.

[0089] Further combined with Figure 1 and Figure 2 When the air flow regulating member 120 is in the first state, the gap defined between every two adjacent guide vanes 1201 is defined as the first air flow passage pore 1202. When the air flow regulating member 120 is in the second state, the gap defined between every two adjacent guide vanes 1201 is defined as the second air flow passage pore 1203. And in the direction parallel to the first central axis, the length of the first air flow passage pore 1202 is greater than the length of the second air flow passage pore 1203. That is, when the air flow regulating member 120 is in the first state, the air flow passage pore of the air flow regulating member 120 becomes longer, the guiding time of the air flow can be longer, the rectifying effect of the air flow regulating member 120 on the air flow is good, the effect of converting the circumferential component velocity of the air flow into the axial component velocity can be improved, so that the air flow converges towards the direction close to the first central axis, and the converging effect of the air flow regulating member 120 on the air flow is realized.

[0090] Combined with Figure 3 and Figure 4 When the air flow regulating member 120 is in the second state, the air flow passes through the second air flow passage pore 1203. Since the length of the second air flow passage pore 1203 is relatively short, the guiding time of the air flow regulating member 120 on the air flow is short, the overall guiding effect of the air flow regulating member 120 is reduced, the circumferential component velocity of the air flow can be effectively maintained when the air flow passes through the air flow regulating member 120, so that the air flow as a whole presents a conical shape when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow.

[0091] It should be noted that the first central axis is arranged parallel or collinear with the rotation center line of the driving fan 300.

[0092] According to the air flow type regulating mechanism 100 of the present invention, by setting the air flow regulating member 120, the air flow type regulating mechanism 100 can adjust the air outlet range and the air outlet intensity. When the air flow regulating member 120 is in the first state, the air flow regulating member 120 can continuously guide the air flow, the circumferential component velocity of the air flow is converted into the axial component velocity, the air flow is in a converging state when flowing out, and the air outlet intensity of the air flow is large; when in the second state, the rectifying effect of the air flow regulating member 120 on the air flow is small, the circumferential component velocity of the air flow can be maintained when the air flow passes through the air flow regulating member 120, so that the air flow can be conical when flowing out of the air flow regulating member 120, ensuring the divergent state when the air flow flows out. And the air flow regulating member 120 can be switched between the first state and the second state, so that the air flow type regulating mechanism 100 has different working states, and the user can adjust the working state of the air flow type regulating mechanism 100 according to actual needs to meet the user's usage requirements.

[0093] Combined with Figure 1 and Figure 2, in some embodiments of the present invention, the air type control mechanism 100 further includes an annular bracket 110. The bracket 110 defines an air duct 101, and the air flow regulating member 120 is mounted to the bracket 110.

[0094] Specifically, the bracket 110 defines the air duct 101, and air flow can flow within the air duct 101. Moreover, the bracket 110 can serve as a mounting carrier for the air flow regulating member 120 to facilitate the installation of the air flow regulating member 120. The bracket 110 can also protect the air flow regulating member 120, preventing external debris from contacting the air flow regulating member 120 and causing the air flow regulating member 120 to malfunction.

[0095] Combined with Figures 1 to 4 , in some embodiments of the present invention, the number of the second air flow through pores 1203 is greater than the number of the first air flow through pores 1202.

[0096] Specifically, the air flow regulating member 120 includes multiple layers of guide vanes 1201. The multiple layers of guide vanes 1201 include a plurality of front side guide vanes 121 and a plurality of rear side guide vanes 122. The plurality of front side guide vanes 121 are arranged at intervals around the first central axis, and a front side gap is formed between every two adjacent front side guide vanes 121. The multiple layers of rear side guide vanes 122 are arranged at intervals around the first central axis, and a rear side gap is formed between every two adjacent rear side guide vanes 122.

[0097] Furthermore, when the air flow regulating member 120 is in the first state, each front side guide vane 121 and each rear side guide vane 122 are arranged opposite to each other in a direction parallel to the first central axis. Each front side gap and each rear side gap are arranged opposite to each other in a direction parallel to the first central axis. The front side gaps and the rear side gaps together form the first air flow through pores 1202. The front side guide vanes 121 and the rear side guide vanes 122 can continuously guide the air flow, improving the effect of converting the circumferential component velocity of the air flow into the axial component velocity, such that the overall air flow after flowing out presents a shape similar to a cylinder, and the wind feeling when the air flow flows out is strong.

[0098] When the air flow regulating member 120 is in the second state, each front guide vane 121 and each rear guide vane 122 are arranged in a staggered manner in a direction parallel to the first central axis, so that each front gap and each rear gap are arranged in a staggered manner in a direction parallel to the first central axis. Each front gap and each rear gap are both the second air flow through pores 1203. Thus, the number of the first air flow through pores 1202 is less than the number of the second air flow through pores 1203. The length of the second air flow through pores 1203 is short, and the front guide vane 121 and the rear guide vane 122 cannot continuously guide the air flow. Compared with the first state, the rectifying effect of the air flow regulating member 120 on the air flow is reduced as a whole. When the air flow passes through the air flow regulating member 120, the circumferential component velocity of the air flow can be maintained, so that the air flow as a whole presents a conical divergence when flowing out of the air flow regulating member 120.

[0099] In some other embodiments of the present invention, the guide vane 1201 can be configured as a structure that can expand and contract in a direction parallel to the first central axis. When the air flow regulating member 120 is in the first state, the guide vane 1201 extends in a direction parallel to the first central axis. When the air flow regulating member 120 is in the second state, the guide vane 1201 contracts in a direction parallel to the first central axis, so that the length of the first air flow through pores 1202 is greater than the length of the second air flow through pores 1203.

[0100] Referring to Figure 2 , in some embodiments of the present invention, the thickness of the front guide vane 121 is H1, the thickness of the rear guide vane 122 is H2, and the total thickness of the front guide vane 121 and the rear guide vane 122 is H3, and H3 satisfies: 10 mm ≤ H3 ≤ 20 mm.

[0101] Similarly, the "thickness of the guide vane" refers to the dimension of the guide vane in the axial direction.

[0102] Specifically, by making 10 mm ≤ H3 ≤ 20 mm, it is beneficial to ensure the guiding effect of the air flow regulating member 120 on the air flow, thereby being beneficial to improving the adjustment effect of the air flow by the air flow regulating mechanism 100. Preferably, H3 is 15 mm, so as to reduce the occupied space of the air flow regulating member 120 while ensuring the adjustment effect of the air flow regulating member 120 on the air flow, thereby being beneficial to reducing the volume of the air flow regulating mechanism 100.

[0103] Among them, when H3 < 10 mm, the guiding effect of the air flow regulating member 120 on the air flow is poor. When H3 > 20 mm, the layout space required by the air flow regulating member 120 is large, resulting in a large volume and weight of the air flow regulating mechanism 100, which is not conducive to the miniaturization and lightweight design of the air flow regulating mechanism 100.

[0104] It can be understood that the thickness H1 of the front guide vane 121 can be the same as the thickness H2 of the rear guide vane 122, both being 7.5 mm. By making the thicknesses of the front guide vane 121 and the rear guide vane 122 the same, it is beneficial to improve the processing convenience of the front guide vane 121 and the rear guide vane 122, and improve the production and processing efficiency of the air flow regulating mechanism 100.

[0105] Combined with Figures 8 to 12 , in some embodiments of the present invention, the bracket 110 includes a fixed ring 112 and a rotating ring 113. The rotating ring 113 is rotatable relative to the fixed ring 112. One of the front guide vane 121 and the rear guide vane 122 is provided on the fixed ring 112 and the other is provided on the rotating ring 113.

[0106] Specifically, the fixed ring 112 and the rotating ring 113 are respectively used to provide installation positions for the front guide vane 121 and the rear guide vane 122. A circular installation space is formed inside the fixed ring 112, and a circular arrangement space is formed inside the rotating ring 113. And the circular installation space and the circular arrangement space are arranged opposite to each other in the axial direction. The front guide vane 121 can be installed on the fixed ring 112, and the rear guide vane 122 can be installed on the rotating ring 113; of course, it can be understood that the front guide vane 121 can also be installed on the rotating ring 113, and the rear guide vane 122 can be installed on the fixed ring 112, as long as it is ensured that the front guide vane 121 and the rear guide vane 122 can rotate relative to each other.

[0107] Furthermore, the rotating ring 113 can rotate relative to the fixed ring 112, so that relative rotation can occur between the front guide vane 121 and the rear guide vane 122. When the air outlet state needs to be adjusted, the rotating ring 113 can be driven to rotate so that relative rotation occurs between the front guide vane 121 and the rear guide vane 122, to adjust the position between the front guide vane 121 and the rear guide vane 122, so that the front guide vane 121 and the rear guide vane 122 are directly opposite in the front-rear direction or the front guide vane 121 and the rear guide vane 122 are arranged offset in the circumferential direction, thereby adjusting the working state of the air flow regulating member 120.

[0108] Combined with Figure 9 and Figure 10In some embodiments of the present invention, a guide vane support 1132 is provided in the rotating ring 113, a guide vane support portion 1121 is provided in the fixed ring 112, the guide vane support 1132 and the rotating ring 113 jointly define an annular arrangement space, the fixed ring 112 and the guide vane support portion 1121 jointly define an annular installation space, one of the front guide vane 121 and the rear guide vane 122 is provided in the fixed ring 112 and the other is provided in the rotating ring 113, and the guide vane support 1132 can be One of the front guide vane 121 or the rear guide vane 122 provides support to facilitate the installation of the front guide vane 121 or the rear guide vane 122, and can ensure the stability of the front guide vane 121 or the rear guide vane 122. Similarly, the guide vane support portion 1121 can provide support for one of the front guide vane 121 or the rear guide vane 122 to facilitate the installation of the front guide vane 121 or the rear guide vane 122, and can ensure the stability of the front guide vane 121 or the rear guide vane 122.

[0109] Among them, the guide vane support 1132 can be connected to the rotating ring 113 through a connecting rib structure to ensure the connection reliability between the guide vane support 1132 and the rotating ring 113. Similarly, the guide vane support part 1121 can be connected to the rotating ring 113 through a connecting rib structure to ensure the connection reliability between the guide vane support part 1121 and the fixed ring 112.

[0110] Reference Figure 11 In some embodiments of the present invention, the wind pattern control mechanism 100 also includes a driving device, which is transmission-connected to the rotating ring 113 to drive the rotating ring 113 to rotate, thereby realizing the relative rotation of the front guide vane 121 and the rear guide vane 122 to adjust the working state of the airflow adjustment member 120, wherein the driving device can realize manual or automatic driving of the rotating ring 113.

[0111] Specifically, when the rotating ring 113 is manually driven, the driving device can be constructed as a toggle lever, which is arranged on the rotating ring 113 and extends in a radial direction away from the central axis of the rotating ring 113. The user can manually drive the toggle lever to rotate the rotating ring 113 relative to the fixed ring 112, thereby realizing the relative rotation of the front guide vane 121 and the rear guide vane 122, so that the airflow adjustment member 120 can switch between the first state and the second state, thereby realizing the user's manual adjustment of the working state of the wind type control mechanism 100.

[0112] When the rotating ring 113 is automatically driven, a driving part (not shown) is provided on the rotating ring 113 , and the driving device can be constructed as a driving motor 140 , and the output end of the driving motor 140 is connected to the driving part to drive the rotating ring 113 to rotate.

[0113] For example, the output end of the drive motor 140 can be configured as a crank, the drive part can be configured as a boss structure, the crank is connected to the drive part. At this time, the rotating ring 113 can be used as a rocker in the four-bar mechanism, and a crank-rocker mechanism is formed between the crank and the rotating ring 113. When the drive motor 140 operates, the crank drives the rotating ring 113 to perform a reciprocating rotational motion over a small distance through the drive part, so that the rotating ring 113 can rotate relative to the fixed ring 112, thereby enabling the front guide vane 121 and the rear guide vane 122 to rotate relative to each other.

[0114] Optionally, the drive motor 140 can be configured as a swing motor. The output end of the drive motor 140 can be configured as a connecting rod, and the drive part can be configured as a connecting rod mounting post. The connecting rod is connected to the connecting rod mounting post, so that a crank-rocker mechanism is formed between the output end of the drive motor 140 and the rotating ring 113. The rotating ring 113 serves as the rocker in the crank-rocker mechanism. When the drive motor 140 operates, the connecting rod drives the rotating ring 113 to rotate through the drive part, thereby enabling the front guide vane 121 and the rear guide vane 122 to rotate relative to each other, so that the front guide vane 121 and the rear guide vane 122 are arranged opposite to or offset from each other in the front-rear direction, realizing the automatic adjustment of the air flow regulating member 120.

[0115] Optionally, the drive motor 140 can be configured as a stepper motor. A drive gear is provided at the output end of the drive motor 140. At this time, the drive part is configured as a mating gear, and the drive gear can be meshed and mated with the mating gear. When the drive motor 140 operates, the drive gear drives the mating gear to rotate to drive the rotating ring 113 to rotate, and the stepper motor rotates reciprocally to drive the rotating ring 113 to perform a reciprocating rotation.

[0116] It can be understood that the drive device can be arranged outside the rotating ring 113, or the drive device can also be arranged inside the rotating ring 113, as long as it is ensured that the drive device can drive the rotating ring 113. The specific arrangement method is not limited herein.

[0117] In a further embodiment of the present invention, a drive motor 140 mounting position is provided in the guide vane support portion 1121, and the drive motor 140 can be mounted in the guide vane support portion 1121. Correspondingly, a drive part is provided in the guide vane support 1132, and the drive part can be connected to the output end of the drive motor 140 to drive the rotating ring 113 to rotate.

[0118] Specifically, in combination with Figures 9 to 11, the driving motor 140 can be configured as a swing motor, the output end of the driving motor 140 is configured as a connecting rod, and the connecting rod extends in the radial direction after extending out of the guide vane support portion 1121. An avoidance groove 1133 is formed on the guide vane support 1132, and the connecting rod can be arranged in the guide vane support 1132 through the avoidance groove 1133 so as to be connected with the driving part. Wherein, the avoidance groove 1133 can be configured as an arc-shaped groove.

[0119] Combined with Figures 9 to 11 , in some embodiments of the present invention, both the front guide vane 121 and the rear guide vane 122 are formed in an arc shape.

[0120] Specifically, the cross-section of the front guide vane 121 perpendicular to the central axis of the air duct space 111 is formed in an arc shape. Similarly, the cross-section of the rear guide vane 122 perpendicular to the central axis of the air duct space 111 is formed in an arc shape to reduce the wind resistance when the air flow passes through the front guide vane 121 and the rear guide vane 122 and ensure the flow effect of the air flow. Of course, it can be understood that the front guide vane 121 and the rear guide vane 122 can also be formed in other shapes, such as a straight line shape.

[0121] In some embodiments of the present invention, at least one layer of guide vanes 1201 rotates relative to the remaining layers of guide vanes 1201 within a set time period; or at least one layer of guide vanes 1201 reciprocally rotates relative to the remaining layers of guide vanes 1201 within a set time period.

[0122] Specifically, at least one layer of guide vanes 1201 can rotate counterclockwise or clockwise around the first central axis relative to the remaining layers of guide vanes 1201 within a set time period. Within the set time period, the guide vanes 1201 can rotate by a certain angle so that the multiple layers of guide vanes 1201 can be arranged facing or offset in the direction parallel to the first central axis, and the air flow regulator 120 can be switched from the first state to the second state or from the second state to the first state to realize the automatic regulation of the working state of the air flow regulator 120.

[0123] Optionally, at least one layer of guide vanes 1201 can reciprocally rotate around the first central axis relative to the remaining layers of guide vanes 1201 within a set time period. For example, at least one layer of guide vanes 1201 can first rotate clockwise around the first central axis by a certain angle relative to the remaining layers of guide vanes 1201 within a set time period so that the multiple layers of guide vanes 1201 can be arranged facing or offset in the direction parallel to the first central axis, and then this layer of guide vanes 1201 rotates counterclockwise around the first central axis to achieve reset, so that the air flow regulator 120 can be switched from the first state to the second state or from the second state to the first state to realize the automatic regulation of the working state of the air flow regulator 120.

[0124] It should be noted that the number of layers of the guide vanes 1201 and the number of the rotating guide vanes 1201 are not specifically limited herein, as long as it is ensured that relative rotation can occur between the multiple layers of guide vanes 1201.

[0125] Combined with Figures 1 to 4 , in some embodiments of the present invention, the air flow regulating member 120 is provided with a first central axis, and a plurality of guide vanes 1201 are arranged at intervals around the first central axis; the air flow regulating mechanism 100 further includes a duct regulating member 130, the duct regulating member 130 forms an air flow regulating cavity 133, the inner wall of the air flow regulating cavity 133 deflects relative to the vertical plane of the first central axis under the action of the duct regulating member 130, the air flow regulating mechanism 100 has a wind concentrating mode and a wind dispersing mode, the inner wall of the air flow regulating cavity 133 deflects a larger angle relative to the vertical plane in the wind dispersing mode than in the wind concentrating mode, so that the air flow is restricted by the inner wall of the air flow regulating cavity 133 in the wind concentrating mode, and the air flow diffuses outward under the guidance of the inner wall of the air flow regulating cavity 133 in the wind dispersing mode.

[0126] Specifically, when the air flow flows into the air flow regulating member 120, the guide vanes 1201 can guide the air flow to adjust the air outlet effect when the air flow flows out of the air flow regulating member 120. Among them, a plurality of guide vanes 1201 can be arranged in one layer, a plurality of guide vanes 1201 are arranged at intervals around the first central axis, and a plurality of guide vanes 1201 can be deflected relative to the first central axis. The guide vanes 1201 deflect a larger angle relative to the first central axis in the wind dispersing mode than in the wind concentrating mode. For example: in the wind concentrating mode, the guide vanes 1201 can be arranged parallel to the first central axis or at a slight angle. When the air flow flows into the air flow regulating member 120 and impacts the guide vanes 1201, the guide vanes 1201 can guide the air flow to converge in the direction of the first central axis; in the wind dispersing mode, the guide vanes 1201 deflect in a direction deviating from the first central axis, and the deflection angle of the guide vanes 1201 relative to the first central axis is larger than that in the wind dispersing mode. The adjustment effect of the guide vanes 1201 on the air flow is reduced, and the air flow can maintain its circumferential component velocity, so that the air flow can be in a divergent state when flowing out of the air flow regulating member 120.

[0127] Optionally, multiple guide vanes 1201 can be configured such that the length of the gap between every two adjacent guide vanes 1201 can be adjusted. In the air-gathering mode, the gap defined between every two adjacent guide vanes 1201 is defined as the first air flow passage pore 1202. In the air-diffusing mode, the gap defined between every two adjacent guide vanes 1201 is defined as the second air flow passage pore 1203. And in the direction parallel to the first central axis, the length of the first flow passage pore is greater than the length of the second air flow passage pore 1203. That is, when in the air-gathering mode, the air flow regulating member 120 has a long guiding time for the air flow, and the air flow regulating member 120 has a good rectifying effect on the air flow, which can improve the effect of converting the circumferential component velocity of the air flow into the axial component velocity, so that the air flow converges in the direction close to the first central axis, realizing the converging effect of the air flow regulating member 120 on the air flow.

[0128] When in the air-diffusing mode, the air flow passes through the second air flow passage pore 1203. Since the length of the second air flow passage pore 1203 is relatively short, the guiding time of the air flow regulating member 120 for the air flow is short, and the overall guiding effect of the air flow regulating member 120 is reduced. When the air flow passes through the air flow regulating member 120, its circumferential component velocity can be effectively maintained, so that the air flow as a whole presents a conical shape when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow.

[0129] Furthermore, the air type regulating mechanism 100 further includes an air duct regulating member 130. An air flow regulating cavity 133 is formed in the air duct regulating member 130. When the air flow flows into the air flow regulating cavity 133, the inner wall of the air flow regulating cavity 133 can guide the air flow to adjust the air outlet feeling and the air outlet range when the air flow flows out of the air duct regulating member 130. When adjusting the air duct regulating member 130, the inner wall of the air flow regulating cavity 133 formed by the air duct regulating member 130 can deflect relative to the vertical plane of the first central axis, so that the adjusting effect of the inner wall of the air flow regulating cavity 133 on the air flow can be adjusted.

[0130] It should be noted that the "vertical plane" does not refer to the plane extending in the vertical direction, but only means perpendicular to the first central axis.

[0131] Furthermore, the air type regulating mechanism 100 has an air-gathering mode and an air-diffusing mode. When the air type regulating mechanism 100 is in the air-gathering mode, the inner wall of the air flow regulating cavity 133 is arranged at an angle with the vertical plane, and the inner wall of the air flow regulating cavity 133 can regularize the air flow, so that the circumferential component velocity of the air flow is converted into the axial component velocity, so that the air flow flowing out of the air duct regulating member 130 converges in the direction close to the first central axis.

[0132] When the wind type control mechanism 100 is in the air-diffusing mode, compared with when the wind type control mechanism 100 is in the air-concentrating mode, the angle formed between the inner wall of the air flow regulating member 120 and the vertical plane is larger, so as to reduce the adjustment effect of the inner wall of the air flow regulating cavity 133 on the circumferential component velocity of the air flow. When the air flow flows out from the air duct regulating member 130, it can still maintain a certain circumferential component velocity, so that the overall air flow presents a conical shape when flowing out, and the air flow is in a divergent state.

[0133] Combined with Figures 1 to 4 , in some embodiments of the present invention, the air duct regulating member 130 is provided on the bracket 110 and is located on the air outlet side of the air flow regulating member 120. The area of the air outlet 131 of the air duct regulating member 130 in the air-concentrating state is smaller than the area of the air outlet 131 in the air-diffusing state.

[0134] It should be noted that the "air outlet side of the air flow regulating member 120" refers to the side where the air flow flows out from the air flow regulating member 120.

[0135] Specifically, the air duct regulating member 130 is disposed on the bracket 110, and the air duct regulating member 130 is located on the air outlet side of the air flow regulating member 120. The air flow flows through the air flow regulating member 120 and then flows into the air duct regulating member 130. The area of the air outlet 131 of the air duct regulating member 130 can be adjusted to further adjust the flow range and intensity of the air flow through the area of the air outlet 131.

[0136] Among them, when the air duct regulating member 130 is in the air-concentrating state, the inner wall of the air duct regulating member 130 can guide the air flow flowing into it, the air duct regulating member 130 can regularize the air flow flowing into it, and the area of the air outlet 131 of the air duct regulating member 130 is small. The air duct regulating member 130 can adjust the circumferential component velocity of the air flow into the axial component velocity, so that the air flow flowing out from the air duct regulating member 130 is more concentrated in the axial direction, has a longer flow distance, and the air flow is stronger.

[0137] When the air duct regulating member 130 is in the air-diffusing state, the area of the air outlet 131 of the air duct regulating member 130 is large, and the interference of the inner wall of the air duct regulating member 130 on the circumferential component velocity of the air flow is small. When the air flow flows out from the air duct regulating member 130, it can still maintain a certain circumferential component velocity, so that the air flow flowing out from the air duct regulating member 130 is more divergent in the radial direction and the air flow is softer.

[0138] Combined with Figure 1 and Figure 2 , when the air flow regulating member 120 is in the first state, the air duct regulating member 130 is in the air-concentrating state. After the air flow flows out from the air flow regulating member 120, the air duct regulating member 130 can further rectify the air flow to ensure the concentrating effect of the air flow when flowing out from the wind type control mechanism; combined with Figure 3 and Figure 4, when the air flow regulating member 120 is in the second state, the air duct regulating member 130 is in the air diffusing state. After the air flow flows out of the air flow regulating member 120, the air duct regulating member 130 can further maintain the circumferential component velocity of the air flow, ensuring the diffusing effect when the air flow flows out of the air pattern regulating mechanism 100.

[0139] Thus, by making the air duct regulating member 130 cooperate with the air flow regulating member 120, the guiding effect of the air pattern regulating mechanism 100 on the air flow is improved, thereby enhancing the regulating effect of the air pattern regulating mechanism on the air flow, making the air outlet feeling significantly different, which is beneficial to meeting different usage requirements of users and improving the user experience.

[0140] In some embodiments of the present invention, the air duct regulating member 130 includes a plurality of swing blades 132. The plurality of swing blades 132 are arranged circumferentially along the bracket 110 of the air pattern regulating mechanism 100, and each swing blade 132 is rotatably disposed on the bracket 110.

[0141] It should be noted that the end of the swing blade 132 close to the bracket 110 in the axial direction is defined as the inner end of the swing blade 132, which can also be understood as the air inlet end of the swing blade 132. The end of the swing blade 132 far from the bracket 110 in the axial direction is defined as the outer end of the swing blade 132, which can also be understood as the air outlet end of the swing blade 132. And the outer end of the swing blade 132 is the outer side of the air duct regulating member 130, and the inner end of the swing blade 132 is the inner side of the air duct regulating member 130. In addition, an air outlet 131 is formed on the outer side of the air duct regulating member 130.

[0142] Combined with Figure 1 and Figure 3 , specifically, a plurality of swing blades 132 are provided. The plurality of swing blades 132 are evenly arranged along the circumferential direction of the bracket 110 to configure the air duct regulating member 130 into a ring shape. The inner end of each swing blade 132 is rotatably connected to the bracket 110. And when the inner end of the swing blade 132 rotates relative to the bracket 110, the outer end of each swing blade 132 can move in a direction approaching or away from the central axis of the air duct regulating member 130, realizing the adjustment of the area of the air outlet 131 of the air duct regulating member 130, so as to reduce or increase the area of the air outlet 131, thereby enabling the air duct regulating member 130 to switch between the air diffusing state and the air concentrating state.

[0143] It can be understood that when the inner end of the swing blade 132 drives the outer end to rotate towards the central axis of the air duct adjusting member 130, the multiple swing blades 132 contract inwards in the radial direction, the area of the air outlet 131 is small, and the multiple swing blades 132 can regularize the air flow to convert the circumferential component velocity of the air flow into the axial component velocity, so that the air outlet intensity is large and the air feeling is strong, realizing the air gathering state of the air duct adjusting member 130; when the inner end of the swing blade 132 drives the outer end to rotate away from the central axis of the air duct adjusting member 130, the multiple swing blades 132 expand outwards in the radial direction, the area of the air outlet 131 increases, and the interference of the swing blade 132 on the circumferential component velocity of the air flow is small. When the air flow discharges from the air duct adjusting member 130, the air flow can still maintain a certain circumferential component velocity, making the air outlet area large and the air outlet soft, realizing the air dispersion state of the air duct adjusting member 130.

[0144] Combined with Figure 2 and Figure 4 as well as Figure 9 and Figure 10 , in some embodiments of the present invention, the rotating ring 113 is located at the air inlet end of the fixed ring 112, the front side guide vane 121 is arranged on the fixed ring 112, the rear side guide vane 122 is arranged on the rotating ring 113, and the air duct adjusting member 130 is arranged on the fixed ring 112 and rotates in linkage with the air flow adjusting member 120.

[0145] Specifically, as Figure 8 shown, the multiple swing blades 132 are arranged at intervals in the circumferential direction. A driving seat 1321 is arranged at the air inlet end of the swing blade 132. A driving rod 1322 is arranged on the side of the driving seat 1321 away from the central axis of the air duct adjusting member 130, and the driving rod 1322 is rotatably connected to the driving seat 1321.

[0146] As Figure 9 shown, the air outlet end of the fixed ring 112 is provided with a plurality of swing blade mounting parts 1122 arranged at intervals in the circumferential direction. The driving seat 1321 is rotatably connected to the swing blade mounting part 1122, and the rotation axis between the driving rod 1322 and the driving seat 1321 is parallel to the rotation axis of the driving seat 1321 and the swing blade mounting part 1122.

[0147] Furthermore, as Figure 10 shown, a plurality of driving blocks 1134 arranged at intervals in the circumferential direction are formed on the outer wall surface of the rotating ring 113. The driving blocks 1134 extend in the radial direction away from the central axis of the rotating ring 113. A driving groove 1135 recessed in the radial direction towards the central axis side of the rotating ring 113 is formed on the driving block 1134. The end of the driving rod 1322 away from the swing blade 132 can be inserted into the driving groove 1135.

[0148] The driving groove 1135 extends obliquely on the driving block 1134, that is, one end of the driving groove 1135 is arranged near the air outlet end of the rotating ring 113 in the axial direction, the other end of the driving groove 1135 is arranged near the air inlet end of the rotating ring 113 in the axial direction, and the arrangement modes of the plurality of driving grooves 1135 are the same.

[0149] Combined with Figure 12 and Figure 13 , when the rotating ring 113 rotates relative to the fixed ring 112, the driving rod 1322 can slide in the driving groove 1135. Due to the inclined arrangement of the driving groove 1135, when the driving rod 1322 slides in the driving groove 1135, it moves in the axial direction towards or away from the air inlet end of the rotating ring 113. Specifically, the driving groove 1135 can drive the driving rod 1322 to move towards the air inlet end of the rotating ring 113. At this time, the driving rod 1322 drives the driving seat 1321 to rotate towards the air inlet end of the rotating ring 113, and at the same time, the driving seat 1321 drives the swing blade 132 to rotate towards the air inlet end of the rotating ring 113. At this time, the air outlet ends of the plurality of swing blades 132 move in the radial direction away from the central axis of the air duct adjusting member 130, the area of the air outlet 131 of the air duct adjusting member 130 increases, the air duct adjusting member 130 is in a state of dissipating wind, and at the same time, the rotating ring 113 drives the rear side guide vane 122 to rotate relative to the front side guide vane 121, and rotates until the plurality of front side guide vanes 121 and the plurality of rear side guide vanes 122 are arranged in a staggered manner one by one, the air flow adjusting member 120 is in the second state, and the air type control mechanism 100 is in the dissipating wind mode.

[0150] When the driving groove 1135 drives the driving rod 1322 to move away from the air inlet end of the rotating ring 113, at this time, the driving rod 1322 drives the driving seat 1321 to rotate away from the air inlet end of the rotating ring 113, and at the same time, the driving seat 1321 drives the swing blade 132 to rotate away from the air inlet end of the rotating ring 113. At this time, the air outlet ends of the plurality of swing blades 132 move in the radial direction towards the central axis of the air duct adjusting member 130, the area of the air outlet 131 of the air duct adjusting member 130 increases, the air duct adjusting member 130 is in a state of concentrating wind, and at the same time, the rotating ring 113 drives the rear side guide vane 122 to rotate relative to the front side guide vane 121, and rotates until the plurality of front side guide vanes 121 and the plurality of rear side guide vanes 122 are arranged opposite to each other one by one, the air flow adjusting member 120 is in the first state, and the air type control mechanism 100 is in the concentrating wind mode.

[0151] Combined with Figure 12 and Figure 13, in a further embodiment of the present invention, a plurality of limiting boxes 1123 are arranged on the fixing ring 112 at intervals in the circumferential direction. The limiting boxes 1123 extend in the radial direction away from the central axis of the fixing ring 112. The plurality of limiting boxes 1123 are arranged in one-to-one correspondence with the plurality of swing blade mounting parts 1122. The driving rod 1322 passes through the limiting box 1123 and is inserted into the driving groove 1135. The limiting box 1123 can limit the driving rod 1322 in the circumferential direction, preventing the driving rod 1322 from deforming during driving and affecting the driving effect on the swing blade 132, and ensuring that the rotating ring 113 can effectively drive the swing blade 132 through the driving rod 1322.

[0152] Combined with Figures 1 to 4 , in some embodiments of the present invention, in the circumferential direction of the bracket 110, there is an overlapping area between adjacent swing blades 132.

[0153] Specifically, the inner ends of the plurality of swing blades 132 are arranged at intervals in the circumferential direction, and a part of the adjacent swing blades 132 can be overlapped. For example, the swing blade 132 can include a first swing blade 1323, a second swing blade 1324, and a third swing blade 1325, and the first swing blade 1323, the second swing blade 1324, and the third swing blade 1325 are arranged adjacent to each other in sequence. In the arrangement direction of the plurality of swing blades 132, one side of the first swing blade 1323 can overlap on the second swing blade 1324, and the side of the second swing blade 1324 away from the first swing blade 1323 can overlap on the third swing blade 1325, so as to realize that there is an overlapping area between adjacent swing blades 132, preventing air leakage of the air duct adjusting member 130 due to the gap between adjacent swing blades 132 and ensuring the air outlet effect of the air type control mechanism 100.

[0154] In some specific embodiments, there are 7 swing blades 132, and the width dimension of the swing blade 132 is H5, where 80mm ≤ H5 ≤ 100mm, so as to ensure that there is an overlapping area between adjacent swing blades 132. It can be understood that the setting of the number of swing blades 132 and the size setting of the overlapping area between adjacent swing blades 132 can be determined according to the size of the air type control mechanism 100, and no specific limitation is made here.

[0155] Among them, the "width dimension of the swing blade 132" refers to the maximum distance between two adjacent side wall surfaces located between the air outlet end and the air inlet end of the swing blade 132.

[0156] Such as Figure 2 shown, in some embodiments of the present invention, in the air gathering state, the cross-sectional area of the air duct adjusting member 130 gradually decreases in the direction towards the air outlet 131; and / or in the air dispersing state, the cross-sectional area of the air duct adjusting member 130 gradually increases in the direction towards the air outlet 131.

[0157] Specifically, in the air concentrating state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis gradually decreases, that is, the air duct regulating member 130 gradually contracts and approaches its central axis, so as to guide the air flow to gradually concentrate, which is beneficial to increasing the flow distance of the air flow in the air outlet direction, and can enhance the intensity of the air flow, making the air flow stronger when flowing out from the air type regulating mechanism 100.

[0158] It should be noted that the "inner wall" refers to the side wall surface of the air duct regulating member 130 on the side closer to its central axis in the radial direction.

[0159] As Figure 4 shown, specifically, in the air dispersing state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis gradually increases, that is, the cross-sectional area of the air duct regulating member 130 gradually increases, so as to guide the air flow to gradually disperse, increase the flow range of the air flow in the radial direction, and reduce the intensity of the air flow, making the air flow softer when flowing out from the air type regulating mechanism 100.

[0160] Or, in the air concentrating state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis gradually decreases, and in the air dispersing state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis remains constant.

[0161] Or, in the air concentrating state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis remains constant, and in the air dispersing state, along the axial direction and in the direction extending from the air flow regulating member 120 to the air duct regulating member 130, the distance between the inner wall of the air duct regulating member 130 and its central axis gradually increases.

[0162] In some embodiments of the present invention, each swing blade 132 is formed as an arc-shaped plate.

[0163] Specifically, a plurality of swing blades 132 are arranged in sequence in the circumferential direction, and each swing blade 132 is formed as an arc-shaped plate, that is, in the radial direction, the inner side wall of each swing blade 132 (that is, the side wall surface of the swing blade 132 on the side closer to the central axis of the air duct regulating member 130 in the radial direction) bulges in an arc shape in the direction away from the central axis of the air duct regulating member 130, so as to reduce the influence of the shape of the inner wall of the air duct regulating member 130 on the air flow, achieve the purpose of reducing wind resistance, and ensure the flow effect of the air flow.

[0164] As Figure 7As shown, in some embodiments of the present invention, a guiding portion 1326 is formed on one side of the swinging blade 132 facing the central axis of the air duct adjusting member 130, and the guiding portion 1326 extends along the circumferential direction of the air duct adjusting member 130.

[0165] Specifically, one end of the swinging blade 132 in the axial direction can be set to have a larger width, and the other end to have a smaller width. The end with the smaller width is defined as the inner end of the swinging blade 132, and the inner end of the swinging blade 132 is rotatably connected to the bracket 110. The end with the larger width is defined as the free end. A guiding portion 1326 is provided on the swinging blade 132, and the guiding portion 1326 is provided to protrude towards one side of the central axis of the bracket 110 in the axial direction. The distance between the swinging blade 132 and the central axis of the air duct adjusting member 130 at the guiding portion 1326 is less than the distance between the swinging blade 132 and the central axis of the air duct adjusting member 130 at other positions.

[0166] Further, when the air flow flows into the air duct adjusting member 130, the circumferential component velocity of the air flow will converge towards the direction close to the central axis of the air duct adjusting member 130 under the action of the guiding portion 1326 when flowing into the air duct adjusting member 130. When the axial component velocity of the air flow is relatively low, a part of the air flow flowing in the circumferential direction converges in the axial direction, making the air flow flowing out of the air duct adjusting member 130 more concentrated and stronger.

[0167] As Figure 3 shown, in some embodiments of the present invention, a plurality of swinging blades 132 include a main swinging blade 1327 and a secondary swinging blade 1328. At least a part of the main swinging blade 1327 overlaps with the secondary swinging blade 1328, and the main swinging blade 1327 is adapted to drive the secondary swinging blade 1328 to rotate relative to the bracket 110 through the overlapping area, so that the area of the air outlet 131 of the air duct adjusting member 130 is adjustable.

[0168] Specifically, the main swinging blade 1327 can be drivingly connected to the rotating ring 113. The rotating ring 113 drives the main swinging blade 1327 to rotate relative to the bracket 110 to realize the outward opening and inward contraction of the main swinging blade 1327. The main swinging blade 1327 drives the secondary swinging blade 1328 to rotate relative to the bracket 110 through the overlapping area to realize the outward opening and inward contraction of the secondary swinging blade 1328, thereby realizing the adjustment of the area of the air outlet 131 of the air duct adjusting member 130, making the air outlet range of the air type control mechanism 100 different, and thus meeting different usage requirements of users.

[0169] Combined Figure 2 and Figure 4 , in some embodiments of the present invention, in the air gathering state, the contraction angle of the swinging blade 132 is less than or equal to 45°, and in the air dispersing state, the expansion angle of the swinging blade 132 is less than or equal to 45°.

[0170] Specifically, the included angle between the axial direction of the swinging blade 132 and the axial direction of the bracket 110 is α. When the swinging blade 132 rotates and opens, the inner diameter of the air duct adjusting member 130 gradually increases. When the swinging blade 132 rotates relative to the bracket 110 to the maximum position, at this time, α ≤ 45°, so as to play a role of pressurizing and decelerating when the inner diameter of the air duct adjusting member 130 gradually expands, making the blown air gentle and soft, and avoiding the situation that the air flow is too compressed due to too large an angle α and cannot flow through the air duct adjusting member 130, thereby avoiding the loss of its dynamic performance of the air flow.

[0171] Further, when the swinging blade 132 rotates and contracts, the inner diameter of the air duct adjusting member 130 gradually decreases. When the swinging blade 132 rotates relative to the bracket 110 to the minimum position, at this time, α ≤ 45°, which can meet the requirement of playing a role of depressurizing and accelerating when the air duct adjusting member 130 gradually contracts, making the blown air strong and concentrated, which can be used for rapid cooling. At the same time, it can avoid the situation that the inner diameter of the air duct adjusting member 130 is too small due to too large an angle α, thereby avoiding a sharp rise in the resistance and a sharp drop in the static pressure inside the air duct adjusting member 130, and the air flow cannot flow through the air duct adjusting member 130. Thus, through the above design, the use function of the air flow regulating mechanism 100 can be improved to meet different use requirements of users.

[0172] Refer to Figure 2 , in some embodiments of the present invention, the length of the air duct adjusting member 130 is H4, where H4 > H3.

[0173] Specifically, the "length H4 of the air duct adjusting member 130" refers to the distance between the air inlet end and the air outlet end of the air duct adjusting member 130.

[0174] The length of the air duct adjusting member 130 is greater than the size of the air flow adjusting member 120 in the axial direction, so that the flow distance of the air flow in the air duct adjusting member 130 is greater than the distance that the air flow passes through the air flow adjusting member 120, which is beneficial to improving the effect of further guiding the air flow by the air duct adjusting member 130, and thus can improve the adjustment effect of the air flow regulating mechanism 100 on the air flow.

[0175] In some embodiments of the present invention, H4 ≥ 40 mm, and H4 / H3 satisfies: H4 / H3 ≥ 2.

[0176] Specifically, by making H4 ≥ 40 mm, the flow distance of the air flow in the air duct adjusting member 130 is ensured, and the adjustment effect of the air duct adjusting member 130 on the air flow is improved, which is beneficial to improving the adjustment effect of the air flow regulating mechanism 100 on the air flow. Preferably, H4 is 40 mm, so as to reduce the occupied space of the air duct adjusting member 130 while ensuring the adjustment effect of the air duct adjusting member 130 on the air flow, which is beneficial to reducing the occupied space of the air flow regulating mechanism 100.

[0177] Among them, when H4 < 40 mm, the flow distance of the air flow in the air duct adjusting member 130 is short, and the adjusting effect of the air duct adjusting member 130 on the air flow is poor, which easily leads to a small difference in the air outlet feeling and affects the user experience.

[0178] By designing the sizes of the air flow adjusting member 120 and the air duct adjusting member 130, making H4 / H3 ≥ 2 is beneficial to further improve the adjusting effect of the air flow by the air flow regulating mechanism 100 and increase the difference in the air outlet feeling.

[0179] Combined with Figure 9 and Figure 11 , in some embodiments of the present invention, the widths of the front guide vane 121 and the rear guide vane 122 are L1, and 2 mm ≤ L1 ≤ 5 mm.

[0180] It should be noted that the "width of the front guide vane 121" refers to the distance between two adjacent side walls between the air inlet end and the air outlet end of the front guide vane 121, and the "width of the rear guide vane 122" refers to the distance between two adjacent side walls between the air inlet end and the air outlet end of the rear guide vane 122.

[0181] Specifically, 2 mm ≤ L1 ≤ 5 mm can meet the structural strength requirements of the front guide vane 121 and the rear guide vane 122, prevent the front guide vane 121 and the rear guide vane 122 from breaking, and at the same time can reduce the space required for arranging the air flow adjusting member 120 and reduce the weight of the air flow adjusting member 120, which is beneficial to realizing the lightweight design of the air flow regulating mechanism 100.

[0182] Combined with Figures 1 to 4 , according to the air flow regulating mechanism 100 of the present invention, it includes: an air duct 101, having an air inlet side and an air outlet side, and the air duct 101 restricts the air flow to blow from the air inlet side to the air outlet side; an air duct adjusting member 130, which is arranged on the air outlet side of the air duct 101, and the air duct adjusting member 130 is provided with an air flow adjusting cavity 133; an air flow adjusting member 120, which is arranged opposite to the air flow adjusting cavity 133, and the air flow adjusting member 120 is configured to adjust the air flow inside the air flow adjusting cavity 133; the air flow adjusting member 120 has a first central axis; the inner wall of the air flow adjusting cavity 133 deflects relative to the vertical plane of the first central axis under the action of the air duct adjusting member 130 to adjust the air flow outside the air flow adjusting cavity 133, so as to adjust the air flow in the middle of the air flow adjusting cavity 133 through the air flow adjusting member 120 and adjust the air flow outside the air flow adjusting cavity 133 through the air duct adjusting member. Therefore, the air flow adjusted by the air flow adjusting member 120 and the air flow adjusted by the air duct adjusting member 130 can affect each other, ensuring the air outlet effect.

[0183] Furthermore, the wind type control mechanism 100 has a wind gathering mode and a wind dispersing mode. The inner wall of the air flow regulating cavity 133 deflects at a greater angle relative to the vertical plane in the wind dispersing mode than in the wind gathering mode, so that the air flow is restricted by the inner wall of the air flow regulating cavity 133 in the wind gathering mode, and the air flow diffuses outward under the guidance of the inner wall of the air flow regulating cavity 133 in the wind dispersing mode.

[0184] Specifically, the wind type control mechanism 100 is provided with an air duct 101. The air flow can flow from the air inlet side of the air duct 101 to the air outlet side of the air duct 101. The air duct 101 can restrict the flow direction of the air flow, prevent the air flow from diverging, and ensure the air outlet effect of the wind type control mechanism 100.

[0185] It should be noted that the "first central axis" is arranged parallel or collinear with the rotation central axis of the driving fan 300.

[0186] Furthermore, the air duct adjusting member 130 is located on the air outlet side of the air duct 101. When the air flow flowing in a spiral shape flows into the air flow regulating cavity 133, the inner wall of the air flow regulating cavity 133 can guide the peripheral air flow (i.e., the part of the air flow relatively close to the inner wall of the air flow regulating cavity 133). The air flow adjusting member 120 faces the air flow regulating cavity 133, and the air flow adjusting member 120 can guide the middle air flow (i.e., the part of the air flow relatively far from the inner wall of the air flow regulating cavity 133) of the air flow flowing in a spiral shape into the air flow regulating cavity 133. By cooperating the air duct adjusting member 130 with the air flow adjusting member 120, it is ensured that the wind type control mechanism 100 can adjust the air flow as a whole, improve the adjustment effect of the wind type control mechanism 100 on the air flow, and is beneficial to increasing the difference in the air outlet feeling in different modes. It should be noted that the air flow adjusting member 120 can guide and adjust the air flow and then make the air flow flow into the air flow regulating cavity 133, or the air flow adjusting member 120 is arranged inside the air duct adjusting member 130 to guide and adjust the air flow flowing into it.

[0187] Furthermore, when adjusting the air duct adjusting member 130, the inner wall of the air flow regulating cavity 133 formed by the air duct adjusting member 130 can deflect relative to the vertical plane of the first central axis, so that the adjustment effect of the inner wall of the air flow regulating cavity 133 on the air flow can be adjusted.

[0188] It should be noted that the "vertical plane" does not refer to the plane extending in the vertical direction, but only means perpendicular to the first central axis.

[0189] Specifically, the air pattern regulating mechanism 100 has a wind converging mode and a wind dispersing mode. When the air pattern regulating mechanism 100 is in the wind converging mode, the inner wall of the air flow regulating cavity 133 is arranged at an angle with respect to the vertical plane, and the inner wall of the air flow regulating cavity 133 can regularize the air flow, so that the circumferential component velocity of the air flow is converted into the axial component velocity, thereby causing the air flow flowing out from the air duct regulating member 130 to converge towards the direction close to the first central axis.

[0190] When the air pattern regulating mechanism 100 is in the wind dispersing mode, compared with when the air pattern regulating mechanism 100 is in the wind converging mode, the angle formed between the inner wall of the air flow regulating member 120 and the vertical plane is larger, so as to reduce the adjustment effect of the inner wall of the air flow regulating cavity 133 on the circumferential component velocity of the air flow. When the air flow flows out from the air duct regulating member 130, it can still maintain a certain circumferential component velocity, so that the overall air flow presents a conical shape when flowing out, and the air flow is in a divergent state.

[0191] Among them, when the air pattern regulating mechanism 100 is in the wind converging mode, the air duct regulating member 130 is in the wind converging state, and the air flow regulating member 120 is in the first state, so that both the air duct regulating member 130 and the air flow regulating member 120 can converge the air flow, ensuring the wind converging effect of the air pattern regulating mechanism 100; when the air pattern regulating mechanism 100 is in the wind dispersing mode, the air duct regulating member 130 is in the wind dispersing state, and the air flow regulating member 120 is in the second state, so that both the air duct regulating member 130 and the air flow regulating member 120 can disperse the air flow, ensuring the wind dispersing effect of the air pattern regulating mechanism 100.

[0192] According to the air pattern regulating mechanism 100 of the present invention, by providing the air flow regulating member 120 and the air duct regulating member 130, and the working states of the air flow regulating member 120 and the air duct regulating member 130 can be switched to adjust the air outlet intensity and the air outlet range of the air pattern regulating mechanism 100. In addition, the air duct regulating member 130 can cooperate with the air flow regulating member 120, so that the air pattern regulating mechanism 100 can adjust the overall air flow, improve the adjustment effect of the air pattern regulating mechanism 100 on the air flow, and the user can adjust the working state of the air pattern regulating mechanism 100 according to the actual use requirements to meet the user's use requirements and improve the user's use experience.

[0193] Combined with Figures 1 to 4 , in some embodiments of the present invention, the air flow regulating member 120 includes a plurality of guide vanes 1201 arranged at intervals around the first central axis. The first air flow passage pores 1202 are defined between adjacent guide vanes 1201 in the wind converging mode, the second air flow passage pores 1203 are defined between adjacent guide vanes 1201 in the wind dispersing mode, and in the direction parallel to the first central axis, the length of the first air flow passage pores 1202 is greater than the length of the second air flow passage pores 1203.

[0194] Specifically, the air flow regulating member 120 includes a plurality of guide vanes 1201. The plurality of guide vanes 1201 extend radially outward around the first central axis, and a gap is formed between every two adjacent guide vanes 1201. The air flow can flow through the gap between every two adjacent guide vanes 1201 to pass through the guide vanes 1201, so that the guide vanes 1201 can guide the air flow to convert its circumferential component velocity into an axial component velocity, and the air flow can flow towards the direction close to the first central axis.

[0195] Further, when the wind type regulating mechanism 100 is in the wind gathering mode, the gap defined between every two adjacent guide vanes 1201 is defined as the first air flow passage pore 1202. When the air flow regulating member 120 is in the second state, the gap defined between every two adjacent guide vanes 1201 is defined as the second air flow passage pore 1203. And in the direction parallel to the first central axis, the length of the first air flow passage pore 1202 is greater than the length of the second air flow passage pore 1203. That is, when the air flow regulating member 120 is in the first state, the air flow regulating member 120 has a long guiding time for the air flow, and the air flow regulating member 120 has a good rectifying effect on the air flow, which can improve the effect of converting the circumferential component velocity of the air flow into the axial component velocity, so that the air flow converges towards the direction close to the first central axis, realizing the converging effect of the air flow regulating member 120 on the air flow.

[0196] When the wind type regulating mechanism 100 is in the wind dispersing mode, the air flow passes through the second air flow passage pore 1203. Since the length of the second air flow passage pore 1203 is relatively short, the air flow regulating member 120 has a short guiding time for the air flow, and the overall guiding effect of the air flow regulating member 120 is reduced. When the air flow passes through the air flow regulating member 120, it can effectively maintain its circumferential component velocity, so that the air flow as a whole presents a conical shape when flowing out of the air flow regulating member 120, ensuring the divergent state of the air flow.

[0197] It should be noted that the first central axis is arranged parallel or collinear with the rotation center line of the driving fan 300.

[0198] Combined Figure 15 and Figure 16 , the fan 1000 according to the present invention includes: a wind type regulating mechanism 100 and a driving fan 300. The wind type regulating mechanism 100 is the above-mentioned wind type regulating mechanism 100, and the driving fan 300 is located on the air inlet side of the air flow regulating member 120.

[0199] It should be noted that the side of the air flow regulating member 120 away from the air duct regulating member 130 in the axial direction is defined as the air inlet side of the air flow regulating member 120.

[0200] Specifically, the driving fan 300 drives air to form an air flow, and the air flow sequentially passes through the air flow regulating member 120 and the air duct regulating member 130. The air flow regulating member 120 and the air duct regulating member 130 guide the air flow, and the air flow flows out of the fan 1000 after flowing out of the air duct regulating member 130, realizing the air supply of the fan 1000.

[0201] Since the fan 1000 is provided with a wind type control mechanism 100, by providing the air flow regulating member 120 and the air duct regulating member 130, and the working states of the air flow regulating member 120 and the air duct regulating member 130 can be switched to adjust the air outlet intensity and air outlet range of the wind type control mechanism 100. In addition, the air duct regulating member 130 can cooperate with the air flow regulating member 120, so that the wind type control mechanism 100 can adjust the overall air flow, improve the adjustment effect of the wind type control mechanism 100 on the air flow, and the user can adjust the working state of the wind type control mechanism 100 according to the actual use requirements to meet the user's use needs and improve the user's use experience.

[0202] Combined with Figure 12 、 Figure 13 and Figure 17 the fan 1000 is provided with a housing 200. An air inlet area 210 and an air outlet area 220 are provided on the housing 200, and the wind type control mechanism 100 and the driving fan 300 can be arranged inside the housing 200.

[0203] Specifically, the housing 200 is constructed as a cylindrical structure with a cavity. The housing 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 inside the housing 200. The housing 200 can play a role in protecting the driving fan 300 and the wind type control mechanism 100, preventing the fan 1000 from being damaged due to external sundries entering the driving fan 300 or the wind type control mechanism 100.

[0204] Furthermore, an air inlet area 210 is formed at the rear side of the housing 200, and outside air enters the housing 200 through the air inlet area 210. An air outlet area 220 is formed at the front side of the housing 200. The air outlet area 220 can be constructed as an opening formed at the front side of the housing 200. The driving fan 300 and the wind type control mechanism 100 can be installed inside the housing 200 through the air outlet area 220, which is convenient for the assembly of the fan 1000. At the same time, the air flow flows out of the fan 1000 through the air outlet area 220 after flowing out of the air duct regulating member 130, realizing the air supply of the fan 1000.

[0205] Optionally, the driving fan 300 can be arranged outside the housing 200. Specifically, the arrangement method of the driving fan 300 can be determined according to the actual installation requirements of the fan 1000, and no specific limitation is made here.

[0206] As Figure 17 shown, in some embodiments of the present invention, when a toggle lever is provided on the rotating ring 113, a through hole 230 is provided on the outer shell 200, and the toggle lever passes through the through hole 230 and can slide in the through hole 230.

[0207] Specifically, the through hole 230 is configured as an oblong hole extending in the circumferential direction of the outer shell 200. The user can drive the toggle lever to slide in the through hole 230, so as to drive the rotating ring 113 to rotate relative to the bracket 110 through the toggle lever.

[0208] In some embodiments of the present invention, a driving device support is further provided inside the outer shell 200. When the driving device is arranged outside the bracket 110, the driving device support is used to install and support the driving device.

[0209] In some embodiments of the present invention, the air type regulating mechanism 100 is detachably connected to the outer shell 200.

[0210] Specifically, referring to Figure 17 , a plurality of bracket mounting seats 114 are arranged on the bracket 110 at intervals in the circumferential direction, and a plurality of bracket fixing seats 240 are arranged in the outer shell 200 in the circumferential direction of the outer shell 200. When the air type regulating mechanism 100 is installed in the outer shell 200, the plurality of bracket mounting seats 114 and the bracket fixing seats 240 are arranged in one-to-one correspondence, and threaded holes are formed on both the bracket mounting seats 114 and the bracket fixing seats 240. A threaded connector can pass through the threaded holes and connect the bracket mounting seats 114 and the bracket fixing seats 240, so that the air type regulating mechanism 100 is connected to the outer shell 200, thereby realizing the detachable connection between the air type regulating mechanism 100 and the outer shell 200, which is convenient for the disassembly, repair or replacement of the air type regulating mechanism 100.

[0211] Optionally, a bracket ball head extending in the axial direction can be provided at the air inlet end of the bracket 110, and two bracket ball heads can be provided. The two bracket ball heads are spaced in the radial direction. A chute can be provided on the outer shell 200. The bracket ball head can be inserted into the chute at a certain angle and the bracket 110 and the outer shell 200 can be fixed by rotation. When it is necessary to disassemble the air type regulating mechanism 100 from the outer shell 200, it can be rotated in the reverse direction and the bracket ball head can be pulled out of the chute.

[0212] Optionally, an external thread can be provided at the air inlet end of the bracket 110, and an internal thread can be formed on the inner side of the outer shell 200. The bracket 110 and the outer shell 200 can be detachably connected by means of threaded connection, which is convenient for the disassembly of the air type regulating mechanism 100.

[0213] Optionally, a magnet seat can be provided at the air inlet end of the bracket 110, and a mating magnet can be provided on the inner side of the housing 200. The magnet seat can be magnetically attracted to the mating magnet to install the air pattern regulating mechanism 100 inside the housing 200. The bracket 110 and the housing 200 are assembled by magnetic attraction, which facilitates the disassembly and assembly of the air pattern regulating mechanism 100.

[0214] In some embodiments of the present invention, the driving fan 300 is an axial flow fan.

[0215] 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 air flow regulating member 120 is driven to flow towards the air flow regulating member 120 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.

[0216] Furthermore, the air flow regulating member 120 and the air duct regulating member 130 can play a role in guiding the air flow. Among them, when the air flow regulating member 120 is in the second state, the air duct regulating member 130 is in a diffusing state, and the interference of the air flow regulating member 120 and the air duct regulating member 130 on the air flow is small. When the air flow flows out of the air pattern regulating mechanism 100, it can still maintain a certain circumferential component velocity, so that the air flow flowing out of the air pattern regulating mechanism 100 diverges more gently in the radial direction.

[0217] When the air flow regulating member 120 is in the first state, the air duct regulating member 130 is in a wind gathering state. After the air flow impacts the air flow regulating member 120, the air flow regulating member 120 guides the air flow, and the circumferential component velocity of the air flow is converted into an axial component velocity. After flowing through the air flow regulating member 120, the air flow further flows into the air duct regulating member 130, and the air duct regulating member 130 further regularizes the air flow flowing into it, so that the air flow flowing out of the air duct regulating member 130 is more concentrated in the axial direction.

[0218] Combined Figures 1 to 4 , in some embodiments of the present invention, the cross-section of each guide vane 1201 is formed as a curve, the curve is an Archimedean spiral, and the bending direction of the curve is opposite to the rotation direction of the blades 310 of the driving fan 300. The cross-section is perpendicular to the rotation center line of the driving fan 300.

[0219] Specifically, the rotation center line of the driving fan 300 is collinearly arranged with the central axis of the bracket 110. The front guide vane 121 and the rear guide vane 122 have the same structure. Taking the front guide vane 121 as an example, the cross-section of the front guide vane 121 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 helix 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 circumferential component velocity direction of the air flow. Such a setting is beneficial to making the air flow flow through the air flow regulating member 120 and contact the air flow regulating member 120, and then the air flow can move along the wall surface of the front guide vane 121 (or the rear guide vane 122) 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.

[0220] As Figure 16 shown, on the first projection plane, the orthographic projection of the air duct space 111 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.

[0221] Specifically, multiple blades 310 are arranged in sequence along the axial direction. When the driving fan 300 operates, it drives multiple blades 310 to rotate, and the blades 310 drive the surrounding air flow to flow during the rotation process, thereby forming an air flow with a certain flow velocity.

[0222] 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.

[0223] Furthermore, the air flow generated by the rotation of the blade 310 can flow into the air duct space 111. On the first projection plane, the outer edge of the orthographic projection of the air duct space 111 can be circumferentially arranged on the outer peripheral side of the circle where the tips 311 of multiple 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 blade 310 blow into the air duct space 111, thereby being beneficial to ensuring that all the air flow generated by the blade 310 flows through the air flow regulating member 120, preventing the air flow from diverging inside the fan 1000, and effectively concentrating the air flow.

[0224] 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.

[0225] In this application, "on the first projection plane, the orthographic projection of the air duct space 111 covers the circle where the tips 311 of multiple blades 310 are located" may mean that the outer edge of the orthographic projection of the air duct space 111 coincides exactly with the above-mentioned circle, or it may mean that the outer edge of the orthographic projection of the air duct space 111 is located outside the above-mentioned circle (i.e., the above-mentioned circle falls within the orthographic projection of the air duct space 111).

[0226] Refer to Figure 16 , a part of the blade 310 of the driving fan 300 extends into the air duct space 111.

[0227] Specifically, the dimension of the air duct space 111 in the radial direction can be greater than the radial dimension of the circle where the tips 311 of multiple blades 310 are located, and a part of the blade 310 extends into the air duct space 111. The blade 310 rotates in the air duct space 111 to generate an air flow. The inner wall surface of the bracket 110 can direct the air flow into the air duct space 111, and the inner wall surface of the bracket 110 can restrict the flow of the air flow to prevent the air flow from diverging before flowing into the air duct space 111, ensuring the flow efficiency of the air flow.

[0228] It can be understood that the end of the blade 310 in the axial direction can be arranged in the air duct space 111, or the blade 310 can be entirely arranged in the air duct space 111. The specific arrangement manner of the blade 310 can be determined according to the overall dimensions of the fan 1000, the blade 310, and the bracket 110, and no specific limitation is made here.

[0229] Refer to Figure 16 , in the direction parallel to the rotation center line of the driving fan 300, the distance between the blade 310 of the driving fan 300 and the air inlet end of the air flow regulating member 120 is L2, and 7mm ≤ L2 ≤ 15mm.

[0230] Specifically, 7mm ≤ L2 ≤ 15mm is for facilitating the air flow formed by the rotation of the blade 310 to flow towards the air flow regulating member 120, which can prevent the risk of mutual interference due to too small a distance between the blade 310 and the air flow regulating member 120, and can avoid the divergence of the air flow in the housing 200 due to too large a distance between the blade 310 and the air flow regulating member 120, ensuring the effect of the air flow, ensuring the air feeling of the air outlet, and making the structure of the fan 1000 compact, reducing the dimension of the fan 1000 in the axial direction. Preferably, L2 is 10mm.

[0231] Refer to Figure 16, in some embodiments of the present invention, on the first projection plane, the diameter of the circle where the tips 311 of the plurality of blades 310 are located is D, and the dimension of the blade 310 in the direction parallel to the central axis of the driving fan 300 is defined as the height dimension H6 of the blade 310, where D = 180 mm and H6 = 80 mm, so as to improve the ability of the blade 310 to drive the airflow, improve the flow efficiency and intensity of the airflow, and thus improve the air outlet feeling of the fan 1000.

[0232] Referring to Figure 14 , through the simulation analysis of the air type control mechanism 100 provided with the air duct adjusting member 130 and the air flow adjusting member 120 in the present application, at the standard test distance, the blowing range of the fan 1000 in the diffused air mode is larger than that in the concentrated air mode, and the average wind speed within the blowing range of the fan 1000 in the diffused air mode is less than that in the concentrated air mode, and the air outlet of the fan 1000 is gentle.

[0233] The blowing range of the fan 1000 in the concentrated air mode is smaller than that in the diffused air mode, and the average wind speed within the blowing range of the fan 1000 in the concentrated air mode is greater than that in the diffused air mode, and the air outlet of the fan 1000 is strong.

[0234] It should be noted that the "blowing range" refers to the area where the wind speed of the fan 1000 is greater than the calibrated wind speed (such as 0.4 m / s), and the "standard test distance" is three times the diameter of the circle where the plurality of tips 311 are located. It can be understood that when conducting simulation analysis and test comparison on the fan 1000, it is not limited to measuring at the above "standard test distance", as long as it is ensured that the fan 1000 is measured at the same position.

[0235] Such as Figure 18 As shown, in some embodiments of the present invention, the fan 1000 further includes an air outlet grille 400, and the air outlet grille 400 is provided in the air outlet area 220 of the fan 1000.

[0236] Specifically, the air outlet grille 400 is installed on the housing 200, the air outlet 131 of the air duct adjusting member 130 is directly opposite to the air outlet grille 400, and a mesh hole structure is formed on the air outlet grille 400 in the air outlet area 220. The air flow can be discharged through the mesh hole structure. At the same time, the air outlet grille 400 can block the internal structure of the fan 1000, prevent the blades 310 from breaking and flying out through the opening during the operation of the fan 1000 and causing harm to users, and prevent users from being injured due to accidental contact with the blades 310, improve the safety of the fan 1000, and the air outlet grille 400 can also reduce the accumulation of dust and other sundries inside the fan 1000.

[0237] Reference Figure 18 Figure 18 , in some embodiments of the present invention, the air outlet grille 400 includes an intermediate region 410 and an outer ring region 420. The air guiding rib 430 of the intermediate region 410 is formed as an arc-shaped rib 431, and the air guiding rib 430 of the outer ring region 420 is formed as a straight rib 432.

[0238] Specifically, the intermediate region 410 and the outer ring region 420 are configured as rings, and the intermediate region 410 and the outer ring region 420 are coaxially arranged. The outer ring region 420 is sleeved outside the intermediate region 410 to achieve a partitioned design of the air outlet grille 400, which is not only beautiful but also enables visualization of the air outlet area 220.

[0239] Further, since the area of the air outlet 131 of the air duct adjusting member 130 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 131 of the air duct adjusting member 130 is different from the air outlet area 220 corresponding when the fan 1000 is in the air-concentrating mode. When the air duct adjusting member 130 is in the air-concentrating state, the air outlet 131 is disposed opposite to the intermediate region 410. At the same time, the intermediate region 410 faces the air flow adjusting member 120. The intermediate region 410 of the air outlet grille 400 can further rectify the air flow, further increasing the axial component velocity of the air flow. When the air duct adjusting member 130 is in the air-diffusing state, the air outlet 131 is disposed opposite to both the outer ring region 420 and the intermediate region 410.

[0240] Further, the air guiding rib 430 of the intermediate region 410 is formed as an arc-shaped rib 431, and the air guiding rib 430 of the outer ring region 420 is formed as a straight rib 432. The arc-shaped rib 431 can be designed based on the principle of Archimedes spiral. A plurality of arc-shaped ribs 431 are evenly spaced along the circumferential direction, and the raising 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.

[0241] When the fan 1000 is in the air-concentrating mode, the air outlet 131 is disposed opposite to the intermediate region 410. After the air flow flows out from the air outlet 131, it flows towards the intermediate 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-converging effect and making the air outlet of the fan 1000 stronger.

[0242] 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 131 is disposed opposite to both the outer ring region 420 and the middle region 410. The air flow flows out from the air outlet 131 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 the air outlet area of the fan 1000 in the radial direction.

[0243] In some embodiments of the present invention, in the direction away from the first central axis, the air outlet end of the straight rib 432 extends obliquely outward in the direction away from the rotation center line of the driving fan 300.

[0244] 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.

[0245] 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.

[0246] In some embodiments of the present invention, the value range of the inclination angle of the straight rib 432 relative to the rotation center line is 20° - 40°.

[0247] Specifically, the value range of the inclination angle of the straight rib 432 with the rotation center line is 20° - 40°. Such a setting can further ensure that 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.

[0248] In some embodiments of the present invention, when the air duct adjusting member 130 is in the air-diffusing state, in the direction towards the air outlet 131, the longitudinal section of the air duct adjusting member 130 extends obliquely outward in the direction away from the rotation center line of the driving fan 300.

[0249] Specifically, when the air duct adjusting member 130 is in the air-diffusing state, in the direction towards the air outlet 131, the radial distance between the inner wall of the air duct adjusting member 130 and the rotation center line of the driving fan 300 gradually increases. Among them, the radial distance between the inner wall of the air duct adjusting member 130 on the side close to the driving fan 300 and the rotation center line of the driving fan 300 is the smallest, and the radial distance between the inner wall of the air duct adjusting member 130 on the side far from the driving fan 300 and the rotation center line of the driving fan 300 is the largest.
