In related art, two operating members are provided on the base, each of which is used to drive the first and second air guide structures to move relative to the base, resulting in a poorly integrated air guide mechanism. Summary of the Invention

[0003] The present application provides an air guide mechanism and an air outlet device, which can improve integration.

[0004] In a first aspect, the present application provides an air guide mechanism comprising a base, a first air guide structure, a second air guide structure, a transmission member, and an operating member.

[0006] In some implementations of the present application, the transmission member is rotatably connected to the base, and an axis of relative rotation and an axis of rotation of the operating portion relative to the transmission member form an angle.

[0007] In some implementations of the present application, the axis of rotation of the operating member relative to the transmission member intersects with the axis of rotation of the transmission member relative to the base.

[0008] In some implementations of the present application, the transmission member is fixedly connected to the first air guide structure.

[0009] In some implementations of the present application, the number of second air-guiding structures is at least two, and at least two second air-guiding structures are rotatably connected to the base, and the relative rotation axis is parallel; the air-guiding mechanism also includes a first connecting rod, and at least two second air-guiding structures are rotatably connected to the first connecting rod, and the cam portion abuts against the first connecting rod to support the second air-guiding structure.

[0010] In some implementations of the present application, the axis of rotation of the second air guide structure relative to the base and the axis of rotation of the operating member relative to the transmission member are perpendicular to the arrangement direction of the at least two second air guide structures.

[0011] In some implementations of the present application, the first connecting rod includes a first abutting portion and a second abutting portion. The first abutting portion and the second abutting portion are arranged opposite to each other along the arrangement direction of at least two second air-guiding structures. The cam portion is arranged between the first abutting portion and the second abutting portion, and both the first abutting portion and the second abutting portion are used to abut against the cam portion.

[0012] In some implementations of the present application, a limiting cavity is formed on the operating member, and the air guide mechanism also includes a limiting member. In the circumferential direction of the operating member relative to the rotation axis of the transmission member, the limiting member and the transmission member are limited. Along the radial direction of the operating member relative to the rotation axis of the transmission member, the limiting member can translate relative to the transmission member to extend into the limiting cavity or escape from the limiting cavity.

[0013] In some implementations of the present application, at least two limiting cavities are formed on the operating member, and the at least two limiting cavities are arranged at intervals along the circumferential direction of the operating member relative to the rotation axis of the transmission member.

[0017] The air guide mechanism provided in this application is configured such that the operating member and the transmission member are limited in position in the direction of movement of the transmission member relative to the base, allowing the operating member to drive the transmission member to move relative to the base, thereby causing the transmission member to drive the first air guide structure to move relative to the base. The operating member and the transmission member are rotatably connected, and the operating member includes a cam portion. This allows the operating member to drive the second air guide structure to move relative to the base during rotation of the operating member relative to the transmission member, i.e., during rotation of the cam portion relative to the transmission member. In this way, the operating member can drive the transmission member to move relative to the base and can rotate relative to the transmission member, allowing the movement of the first and second air guide structures to be controlled by a single operating member, resulting in a high degree of integration of the air guide mechanism.

[0040] An embodiment of the present application provides an air outlet device, which can be implemented in various forms. For example, it can be a fan or an air conditioner, and the air conditioner can be a cabinet air conditioner, a wall-mounted air conditioner, or a central air conditioner.

[0041] Please refer to Figure 1 and Figure 2 The air outlet device in the embodiment of the present application includes a power mechanism 1 and an air guide mechanism. The power mechanism 1 is used to output airflow; the air guide mechanism is arranged on the air outlet side of the power mechanism 1. The air guide mechanism is arranged on the air outlet side of the power mechanism 1, that is, the air outlet of the power mechanism 1 faces the air guide mechanism. The power mechanism 1 outputs airflow in the direction of the airflow. After the airflow leaves the power mechanism 1, it passes through the air guide mechanism, which can achieve the effect of adjusting the wind direction.

[0042] Please refer to Figure 1 and Figure 2 The power mechanism 1 in the embodiment of the present application can be implemented in various forms. For example, it can be a centrifugal fan, an axial flow fan, a mixed flow fan or a cross flow fan.

[0043] Please refer to Figure 1 and Figure 2 In some embodiments of the present application, the air outlet device is an air conditioner, and the air outlet device also includes an evaporator 3. In some embodiments of the present application, the evaporator 3 can be disposed on the air inlet side of the power mechanism 1. In some embodiments of the present application, the evaporator 3 can also be disposed on the air outlet side of the power mechanism 1, and located between the air guide mechanism and the power mechanism 1. After the airflow passes through the evaporator 3, the temperature is reduced, which can achieve the purpose of regulating the ambient temperature.

[0044] Please refer to Figure 2、 Figure 3 and Figure 4 The air guide mechanism provided in the embodiment of the present application includes a base 201, a first air guide structure 202, a second air guide structure 203, a transmission member 204, and an operating member 205. The first air guide structure 202 is movably connected to the base 201; the second air guide structure 203 is movably connected to the base 201; the transmission member 204 is movably connected to the base 201 and is in transmission connection with the first air guide structure 202 to drive the first air guide structure 202 to move relative to the base 201; the operating member 205 is rotatably connected to the transmission member 204 and is limited by the transmission member 204 in the direction of movement of the transmission member 204 relative to the base 201; the operating member 205 has a cam portion 2051, the outer peripheral surface of which is supported by the second air guide structure 203 to drive the second air guide structure 203 to move relative to the base 201.

[0045] By limiting the operating member 205 and the transmission member 204 in the direction of movement of the transmission member 204 relative to the base 201, the operating member 205 can drive the transmission member 204 to move relative to the base 201, thereby causing the transmission member 204 to drive the first air guide structure 202 to move relative to the base 201. The operating member 205 is rotatably connected to the transmission member 204, and the operating member 205 has a cam portion 2051. Therefore, during the rotation of the operating member 205 relative to the transmission member 204, that is, during the rotation of the cam portion 2051 relative to the transmission member 204, the cam portion 2051 can drive the second air guide structure 203 to move relative to the base 201. In this way, the operating member 205 can drive the transmission member 204 to move relative to the base 201 and can rotate relative to the transmission member 204, so that the movement of the first air guide structure 202 and the second air guide structure 203 can be controlled by a single operating member 205, resulting in a high degree of integration of the air guide mechanism.

[0046] Please refer to Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present application, the first air guide structure 202 and the second air guide structure 203 can be implemented in various forms, for example, they can be air duct members, air guide plates or sweeping fan blades.

[0047] Please refer to Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present application, the movable connection between the first air guide structure 202 and the base 201 can be implemented in various forms. The movable connection between the first air guide structure 202 and the base 201 can be implemented in various forms. For example, it can be a rotating connection or a sliding connection.

[0048] Please refer to Figure 2 、 Figure 3 and Figure 4For example, in some embodiments of the present application, at least one of the first air guide structure 202 and the second air guide structure 203 can be a sweeping fan blade, which is rotatably connected to the base 201, and the thickness direction of the sweeping fan blade is perpendicular to the axis of rotation of the sweeping fan blade relative to the base 201.

[0049] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, both the first air guide structure 202 and the second air guide structure 203 are sweeping fan blades. The axis of rotation of the first air guide structure 202 relative to the base 201 forms an angle with the axis of rotation of the second air guide structure 203 relative to the base 201. For example, the angle can be 90 degrees, 60 degrees, 45 degrees, or 30 degrees. The second air guide structure 203 can be arranged on the air inlet side of the first air guide structure 202, and the first air guide structure 202 can be arranged on the air outlet side of the second air guide structure. In this way, the airflow output by the power mechanism 1 passes through the second air guide structure 203 and the first air guide structure 202 in sequence. Alternatively, the second air guide structure 203 can be arranged on the air outlet side of the first air guide structure 202, and the first air guide structure 202 can be arranged on the air inlet side of the second air guide structure. In this way, the airflow output by the power mechanism 1 passes through the second air guide structure 203 and the first air guide structure 202 in sequence. The wind flow is discharged from the wind guide mechanism after being adjusted in direction twice. The personnel can control the first wind guide structure 202 to rotate relative to the base 201 through the operating part 205, and control the second wind guide structure 203 to rotate relative to the base 201, so that the wind direction of the wind flow discharged by the wind guide mechanism can be adjusted in a large range.

[0050] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the first air guide structure 202 may be one of left-right swept fan blades and up-down swept fan blades, and the second air guide structure 203 may be the other of left-right swept fan blades and up-down swept fan blades. The left-right swept fan blades and up-down swept fan blades have the same meanings as those generally understood by those skilled in the art of the embodiments of the present application and are not further described here. Based on this, the base 201 may include a volute 2011 and an air outlet frame 2012. The left-right swept fan blades are mounted on the volute 2011, and the up-down swept fan blades are mounted on the air outlet frame 2012.

[0051] Please refer to Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present application, please refer to the first axis b in the figure for the axis about which the operating member 205 rotates relative to the transmission member 204.

[0052] Please refer to Figure 2 、 Figure 3 and Figure 4In some embodiments of the present application, the operating member 205 is a rod-shaped structure, the axis of the rod-shaped structure being the same as the first axis b. The first end of the rod-shaped structure is rotatably connected to the transmission member 204, and the second end of the rod-shaped structure is for human operation. The rod-shaped structure of the operating member 205 facilitates human operation. In some embodiments of the present application, the operating member 205 is formed with a flange 2052 extending radially outward. The flange 2052 and the cam portion 2051 are arranged parallel to the first axis b. Thus, a person can operate the flange 2052 to control the operating member 205, making operation more convenient.

[0053] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, a through hole 2041 is formed on the operating member 205, and the axis of the through hole 2041 is the first axis b. The operating member 205 cooperates with the through hole 2041 to be rotatably connected with the transmission member 204. In this way, the installation of the operating member 205 on the transmission member 204 is relatively simple and reliable.

[0054] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, along the first direction, the side surface of at least one side of the cam portion 2051 is supported by the second air guide structure 203, and the first direction and the direction of movement of the transmission member 204 relative to the base 201 are perpendicular to the axis of rotation of the operating member 205 relative to the transmission member 204. With such a structural form, during the movement of the transmission member 204 relative to the base 201, in the first direction, the position of the axis of the cam relative to the base 201 remains unchanged, so that the movement of the first air-guiding structure 202 relative to the base 201 and the movement of the second air-guiding structure 203 relative to the base 201 have little mutual influence, and the operating member 205 can independently control the first air-guiding structure 202 and the second air-guiding structure 203, that is, the movement of the transmission member 204 relative to the base 201 can drive the first air-guiding structure 202 to move relative to the base 201, but it is not easy to drive the second air-guiding structure 203 to move relative to the base 201, and the movement of the cam relative to the transmission member 204 can drive the second air-guiding structure 203 to move relative to the base 201, but it is not easy to drive the first air-guiding structure 202 to move relative to the base 201.

[0055] Please refer to Figure 2 、 Figure 3 and Figure 4 It can be understood that, in the embodiment of the present application, along the first direction, the side surface of at least one side of the cam portion 2051 is a part of the outer peripheral surface of the cam portion 2051.

[0056] Please refer to Figure 2 、 Figure 3 and Figure 4In the embodiment of the present application, there may be various forms of realizing the movable connection between the transmission member 204 and the base 201. For example, the transmission member 204 and the base 201 may be slidably connected, and the direction of relative sliding may not be restricted. For example, it may be perpendicular or parallel to the axis of rotation of the operating member 205 relative to the transmission member 204.

[0057] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the transmission member 204 is rotationally connected to the base 201, and the axis of relative rotation forms an angle with the axis of rotation of the operating portion relative to the transmission member 204. With this structural form, the transmission member 204 is rotationally connected to the base 201, and the installation of the transmission member 204 on the base 201 is relatively convenient. The axis of rotation of the transmission member 204 relative to the base 201 and the axis of rotation of the operating portion relative to the transmission member 204 form an angle, so that in the direction of movement of the transmission member 204 relative to the base 201, the operating member 205 is limited by the transmission member 204, so that the transmission member 204 can be moved relative to the base 201 by operating the operating member 205.

[0058] Please refer to Figure 2 、 Figure 3 and Figure 4 In the embodiment of the present application, please refer to the second axis c in the figure for the axis about which the transmission member 204 rotates relative to the base 201.

[0059] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the axis of rotation of the operating member 205 relative to the transmission member 204 intersects with the axis of rotation of the transmission member 204 relative to the base 201. In this structural form, during the rotation of the transmission member 204 relative to the base 201, the movement of the cam portion 2051 relative to the base 201

[0060] The amplitude is small, which is convenient for personnel operation.

[0061] Please refer to Figure 2 、 Figure 3 and Figure 4 In some embodiments of the present application, the axis of rotation of the transmission member 204 relative to the base 201 is perpendicular to the axis of rotation of the operating portion relative to the transmission member 204. With this structure, the axial movement of the cam portion 2051 is relatively small during the rotation of the transmission member 204 relative to the base 201, thereby ensuring stable support between the cam portion 2051 and the second air guide structure 203.

[0062] Please refer to Figure 2 、 Figure 3 and Figure 4In the embodiment of the present application, the transmission connection between the transmission member 204 and the first air-guiding structure 202 can be realized in various forms. For example, the transmission connection can be through gears, connecting rod mechanisms or synchronous belts, or the transmission member 204 can be fixedly connected to the first air-guiding structure 202 to achieve the transmission connection between the transmission member 204 and the first air-guiding structure 202. In this way, the connection between the transmission member 204 and the first air-guiding structure 202 is simple and reliable.

[0063] For example, in some embodiments of the present application, the transmission member 204 is rotationally connected to the first air-guiding structure 202 through gears. Specifically, the air-guiding mechanism also includes a first gear and a second gear. The first gear is rotationally connected to the base 201 and is fixedly connected to the first air-guiding structure 202. The second gear is rotationally connected to the base 201 and is fixedly connected to the transmission member 204. The first gear is engaged with the second gear. In this way, the transmission member 204 can drive the second gear to rotate relative to the base 201 to drive the first gear to rotate relative to the base 201, thereby driving the first air-guiding structure 202 to rotate relative to the base 201.

[0064] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments of the present application, the transmission member 204 is fixedly connected to the first air-guiding structure 202, and the axis of rotation of the operating member 205 relative to the transmission member 204 intersects with the axis of rotation of the transmission member 204 relative to the base 201. With this structural form, the transmission member 204 is fixedly connected to the first air-guiding structure 202, the structure is simple, and the transmission connection between the transmission member 204 and the first air-guiding structure 202 is more convenient. Moreover, the rotation direction of the transmission member 204 relative to the base 201 is consistent with the rotation direction of the first air-guiding structure 202 relative to the base 201, making the operation more intuitive. In some embodiments of the present application, a first mark is also provided on the operating member 205, and the first mark is used to guide personnel to operate the operating member 205. The personnel can drive the operating member 205 in the direction indicated by the first mark to rotate the transmission member 204 relative to the base. At this time, the first air-guiding structure 202 also rotates relative to the base in the direction indicated by the first mark.

[0065] In some embodiments of the present application, the axis of rotation of the operating member 205 relative to the transmission member 204 intersects the axis of rotation of the transmission member 204 relative to the base 201. The operating member 205 is disposed on one side of the first air guide structure 202 along the axis of rotation of the transmission member 204 relative to the base 201. With this structure, the operating member 205 avoids the airflow output by the first air guide structure 202, and the operating member 205 has little effect on the airflow and direction.

[0066] Please refer to Figure 9 and Figure 10In some embodiments of the present application, there are at least two second air-guiding structures 203, and at least two second air-guiding structures 203 are rotatably connected to the base 201, with the relative rotation axis being parallel. The air-guiding mechanism further includes a first connecting rod 206, and at least two second air-guiding structures 203 are rotatably connected to the first connecting rod 206. The cam portion 2051 abuts the first connecting rod 206 to provide support for the second air-guiding structure 203. With this structural form, by abutting the cam portion 2051 with the first connecting rod 206, one cam portion 2051 can drive the synchronous rotation of at least two second air-guiding structures 203. This fully utilizes the cam portion 2051, improves system integration, and helps reduce costs. Furthermore, during the rotation of the second air-guiding structure 203 relative to the base 201, the first connecting rod 206 maintains its posture relative to the base 201 and only performs translational motion relative to the base 201, causing the cam portion 2051 to abut against the first connecting rod 206, thereby providing high reliability.

[0067] Please refer to Figure 9 and Figure 10 It is understood that in the embodiment of the present application, the axes of rotation of at least two second air guide structures 203 relative to the base 201 are coplanar. The axes of rotation of at least two second air guide structures 203 relative to the connecting rod are parallel and coplanar, and the axes of rotation of the second air guide structures 203 relative to the connecting rod are parallel to the axes of rotation of the second air guide structures 203 relative to the base 201.

[0068] Please refer to Figure 9 and Figure 10 In some embodiments of the present application, the axis of rotation of the second air guide structure 203 relative to the base 201 and the axis of rotation of the operating member 205 relative to the transmission member 204 are perpendicular to the arrangement direction of the at least two second air guide structures 203. With this structure, the force applied by the cam portion 2051 to the connecting rod is relatively consistent with the direction of movement of the connecting rod relative to the base 201. The cam portion 2051 can relatively smoothly drive the second air guide structure 203 to move relative to the base 201, and the movement of the second air guide structure 203 relative to the base 201 is less likely to get stuck.

[0069] Please refer to Figure 9 and Figure 10In some embodiments of the present application, the first connecting rod 206 includes a first abutting portion 2061 and a second abutting portion 2062. Along the arrangement direction of at least two second air-guiding structures 203, the first abutting portion 2061 and the second abutting portion 2062 are arranged opposite to each other, and the cam portion 2051 is arranged between the first abutting portion 2061 and the second abutting portion 2062. The first abutting portion 2061 and the second abutting portion 2062 are both used to abut against the cam portion 2051. With such a structural form, during the rotation of the cam portion 2051, it abuts against the first abutting portion 2061 and the second abutting portion 2062 respectively, which can drive the first connecting rod 206 to move in two opposite directions, so that the second air-guiding structure 203 can rotate in two opposite directions. During the rotation of the cam portion 2051, the cam portion 2051 abuts against the first abutting portion 2061 to push the first air-guiding structure 202 to move relative to the base 201, which can drive the second air-guiding structure 203 to rotate forward relative to the base 201. During the rotation of the cam portion 2051, it abuts against the second abutting portion 2062 to push the second air-guiding structure 203 to move relative to the base 201, which can drive the second air-guiding structure 203 to reverse relative to the base 201.

[0070] Please refer to Figure 9 and Figure 10 In some embodiments of the present application, the first connecting rod 206 further includes a limiting portion, which is spaced apart from the operating member 205 along the direction of movement of the transmission member 204 relative to the base 201. With this structure, the limiting portion can limit the range of movement of the transmission member 204 relative to the base 201, thereby limiting the range of movement of the first air guide structure 202 relative to the base 201.

[0071] Please refer to Figure 9 and Figure 10 In some embodiments of the present application, there are two limiting portions, namely a first limiting portion 2063 and a second limiting portion 2064. The first limiting portion 2063 and the second limiting portion 2064 are disposed opposite each other along the direction of movement of the transmission member 204 relative to the base 201, and the operating member 205 is disposed between the first limiting portion 2063 and the second limiting portion 2064. With this structure, the first limiting portion 2063 and the second limiting portion 2064 can limit the range of movement of the transmission member 204 in two opposite directions, thereby limiting the range of movement of the first air guide structure 202 in two opposite directions.

[0072] Please refer to Figure 9 and Figure 10In some embodiments of the present application, a limiting hole is formed on the first connecting rod 206. The first abutting portion 2061, the second abutting portion 2062, the first limiting portion 2063, and the second limiting portion 2064 are all formed on the inner surface of the limiting hole in the depth direction. In this way, the first abutting portion 2061, the second abutting portion 2062, the first limiting portion 2063, and the second limiting portion 2064 are more convenient to manufacture.

[0073] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments of the present application, the air guide mechanism further includes a third air guide mechanism 208. The axis of rotation of the third air guide mechanism 208 relative to the base 201 is parallel to the axis of rotation of the first air guide structure 202 relative to the base 201. The air guide mechanism further includes a second connecting rod 207. At least the first air guide structure 202 and the third air guide structure are both rotatably connected to the second connecting rod 207. With this structural form, the transmission member 204 can not only drive the first air guide structure 202 to move relative to the base 201, but also drive the third air guide structure to move relative to the base 201. The transmission member 204 is fully utilized, which is conducive to improving the integration of the air guide mechanism.

[0074] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 It can be understood that, in the embodiment of the present application, the axis of rotation of the first air guide structure 202 relative to the connecting rod and the axis of rotation of the third air guide structure relative to the connecting rod are parallel to the axis of rotation of the first air guide structure 202 relative to the base 201.

[0075] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In some embodiments of the present application, there are at least two third air guide structures, each of which is rotatably connected to the base 201 and parallel to the axis of relative rotation. Furthermore, each of the at least two third air guide structures is rotatably connected to the second connecting rod 207. With this structure, the transmission member 204 can drive the movement of the at least two third air guide members, fully utilizing the moving members and facilitating improved integration of the air guide mechanism.

[0076] Please refer to Figure 5 、 Figure 6 、 Figure 7 and Figure 8 In the embodiment of the present application, the third air guide structure can be of various types, for example, it can be an air duct, an air guide plate or a sweeping fan blade, etc.

[0077] Please refer to Figure 5 、 Figure 6、 Figure 7 and Figure 8 In some embodiments of the present application, a rotating shaft 2081 is fixed to the third air guide structure. The rotating shaft 2081 is located at one end of the third air guide mechanism 208 in the axial direction of the rotating shaft 2081. A connecting hole is formed on the base 201, and the rotating shaft 2081 cooperates with the connecting hole to rotatably connect the third air guide structure to the base 201. With this structural form, the rotational connection between the third air guide structure and the base 201 can be achieved more conveniently. In some embodiments of the present application, the third air guide structure is rotatably connected to the support rod 209 in the middle of the axial direction of the rotating shaft 2081. This helps to improve the stability of the installation of the third air guide structure.

[0078] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, a limiting cavity is formed on the operating member 205, and the air guide mechanism further includes a limiting member 210. The limiting member 210 and the transmission member 204 are limited in position circumferentially about the rotation axis of the operating member 205 relative to the transmission member 204. The limiting member 210 can translate relative to the transmission member 204 in the radial direction of the rotation axis of the operating member 205 relative to the transmission member 204, thereby extending into or out of the limiting cavity. With this structural form, the limiting member 210 can limit the rotation of the operating member 205 relative to the transmission member 204, thereby limiting the movement of the second air guide structure 203 relative to the base 201. The personnel can first put the limiting member 210 in a state of being out of the limiting cavity, and control the operating member 205 to rotate the operating member 205 relative to the base 201 to adjust the second air-guiding structure 203 to the target position. When the second air-guiding structure 203 is in the target position, the limiting member 210 can be extended into the limiting cavity to limit the rotation of the operating member 205 relative to the transmission member 204, so that the second air-guiding structure 203 is firmly maintained in the target position, and the second air-guiding structure 203 is not easily affected by environmental factors or wind flow and deviates from the target position.

[0079] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, when the limiting member 210 extends into the limiting cavity, the limiting member 210 is in contact with the inner surface of the limiting cavity. This structure ensures a tight fit between the limiting member 210 and the limiting cavity, which helps to keep the second air guide structure 203 firmly in the target position.

[0080] Please refer to Figure 11 and Figure 12In some embodiments of the present application, the operating member 205 is formed with at least two limiting cavities, spaced apart along the circumference of the operating member 205's rotational axis relative to the transmission member 204. This structure allows the second air guide structure 203 to be securely held at at least two target positions relative to the base 201, enabling step-by-step adjustment. The second air guide structure 203 can stably guide airflow in at least two directions, providing a highly adaptable air guide mechanism.

[0081] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, the operating member 205 includes a gear portion 2053. The axis of the gear portion 2053 is aligned with the axis of rotation of the operating member 205 relative to the transmission member 204. The gear portion 2053 is fixed relative to the cam portion 2051. The arrangement direction of the gear portion 2053 and the cam portion 2051 is parallel to the axis of rotation of the operating member 205 relative to the transmission member 204. The limiting cavity is the tooth groove of the gear. This structure makes the limiting cavity easier to manufacture.

[0082] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, the air guide mechanism further includes an elastic member 211, which is used to drive the limiting member 210 into the limiting cavity. With this structure, the elastic member 211 can securely retain the limiting member 210 within the limiting cavity, preventing the limiting member 210 from easily falling out of the limiting cavity, thereby maintaining the air guide structure in a stable position relative to the base 201.

[0083] Please refer to Figure 11 and Figure 12 The elastic member 211 in the embodiment of the present application can be implemented in various forms, such as a tension spring, a compression spring, a coil spring or a torsion spring, etc., and the embodiment of the present application does not limit this.

[0084] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, the transmission member 204 is rotationally connected to the base 201, and the axis of relative rotation forms an angle with the axis of rotation of the operating member 205 relative to the transmission member 204. The air guide mechanism further includes a sliding member 212, which is slidably connected to the base 201 along the circumferential direction of the axis of rotation of the transmission member 204 relative to the base 201. The operating member 205 is rotationally connected to the sliding member 212, and the axis of relative rotation is the same as the axis of rotation of the operating member 205 relative to the base 201. The limiting member 210 is slidably connected to the sliding member 212. The sliding member 212 is fixed relative to the transmission member 204 and its position relative to the base 201 is less restricted. Disposing the limiting member 210 on the sliding member 212 facilitates processing and manufacturing.

[0085] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, a mounting hole 2123 is formed on the sliding member 212. The axis of the mounting hole 2123 serves as the axis of rotation of the operating member 205 relative to the transmission member 204. The operating member 205 cooperates with the mounting hole 2123 to be rotationally connected to the sliding member 212. In this way, the rotational connection between the operating member 205 and the sliding member 212 is achieved more conveniently and at a lower cost.

[0086] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, a sliding hole 2122 is formed on the sliding member 212, and a latch 20132 is formed on the base 201. The axial direction of the latch 20132 is radial to the axis of rotation of the transmission member 204 relative to the base 201. The latch 20132 cooperates with the sliding hole 2122 to achieve a sliding connection between the sliding member 212 and the base 201. In this way, the sliding connection between the sliding member 212 and the base 201 through the cooperation between the latch 20132 and the sliding hole 2122 is relatively convenient to manufacture.

[0087] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, the sliding hole 2122 is a through-hole, and the distal end of the latch 20132 extends radially outward to form an abutment portion, with the side surface of the abutment portion near the front end of the latch 20132 abutting against the end surface of the sliding hole 2122. In this way, the sliding member 212 and the base 201 are positioned axially at the upper limit of the latch 20132, and the installation of the sliding member 212 on the base 201 is relatively stable.

[0088] Please refer to Figure 11 and Figure 12 In some embodiments of the present application, a mounting post is formed on the position-limiting member 210, and the sliding member 212 is sleeved on the mounting post to be slidably connected to the position-limiting member 210. With such a structure, the installation reliability of the position-limiting member 210 on the sliding member 212 is high and the cost is low.

[0089] Please refer to Figure 11 and Figure 12In some embodiments of the present application, the elastic member 211 is connected between the limiting member 210 and the sliding member 212. In this way, the elastic member 211 is arranged on the sliding member 212, and the installation of the elastic member 211 is more convenient. In some embodiments of the present application, a support portion 2121 is formed on the sliding member 212, and a mounting column is formed on the support portion 2121. The axial direction of the mounting column is the radial direction of the axis of rotation of the operating member 205 relative to the transmission member 204. The elastic member 211 is a compression spring. The elastic member 211 is sleeved on the mounting column. The elastic direction of the elastic member 211 is the axial direction of the mounting column. One end of the elastic member 211 is supported by the support portion 2121, and the other end is supported by the limiting member 210. In this way, the elastic member 211 is sleeved on the mounting column, and the installation of the elastic member 211 is more stable.

[0090] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the base 201 includes a housing having a housing formed therein, wherein the first air guide structure 202, the second air guide structure 203, and the transmission member 204 are all disposed within the housing. The housing has an air outlet disposed on the air outlet side of the first air guide structure 202 and the second air guide structure 203. Thus, the housing can protect the first air guide structure 202, the second air guide structure 203, and the transmission member 204, thereby improving the reliability of the air guide mechanism.

[0091] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the air outlet frame 2012 and the volute tongue 2011 are also disposed in the accommodating cavity. Such a structural form is beneficial to improving the reliability of the air guide mechanism.

[0092] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the housing includes a control panel 2013 having a strip-shaped hole 20131 formed therein. The strip-shaped hole 20131 extends in the same direction as the direction of movement of the transmission member 204 relative to the base 201. The operating member 205 slides with the transmission member 204 along the direction of the strip-shaped hole 20131. With this structure, the operating member 205 is mounted within the strip-shaped hole 20131, providing a relatively stable installation. Furthermore, the strip-shaped hole 20131 guides the movement of the operating member 205, thereby reducing any shaking of the operating member 205 relative to the base 201.

[0093] In some embodiments of the present application, a second mark is further provided on the control panel 2013, and the second mark is used to guide a person to operate the operating member 205. The person can drive the operating member 205 in the direction indicated by the second mark, so that the operating member 205 rotates relative to the transmission member 204. At this time, the second air guide structure 202 also rotates relative to the base in the direction indicated by the second mark.

[0094] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the control panel 2013 and the air outlet are located on the same side of the receiving chamber along the direction of the air outlet. It is understood that the air outlet of the air outlet mechanism is arranged in a position that is easily accessible to personnel, and the control panel 2013 and the air outlet are located on the same side of the receiving chamber for easy access.

[0095] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the strip-shaped hole 20131 is a through hole. Along the depth direction of the strip-shaped hole 20131, one end of the operating member 205 is rotatably connected to the transmission member 204, and the other end extends outside the accommodating cavity through the strip-shaped hole 20131. With this structure, the control panel 2013 can shield the transmission member 204, which helps improve the smoothness of the air guide mechanism. A person can control the movement of the operating member 205 by grasping the other end of the operating member 205, making operation more convenient.

[0096] Please refer to Figure 11 、 Figure 12 and Figure 13 In some embodiments of the present application, the slider 212 is disposed within the accommodating cavity. This allows the control panel 2013 to shield the slider 212, thereby improving the smoothness of the air guide mechanism's appearance. In some embodiments of the present application, the slider 212 shields the strip-shaped hole 20131. This structural form improves the smoothness of the air guide mechanism's appearance and reduces the amount of impurities that pass through the strip-shaped hole 20131, thereby improving the reliability of the air guide mechanism.
