Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.

It should be noted that, in the description of the present application, if the terms "first", "second", etc. appear, the terms "first", "second", etc. are only used for convenience in describing different components or names, and cannot be understood as indicating or implying a sequential relationship, relative importance, or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, if "and/or" is presented throughout, it is meant to include three juxtapositions, exemplified by "A and/or B," including either scheme A, or scheme B, or schemes in which both A and B are satisfied.

Referring to fig. 1 to 9, in an embodiment of the present invention, an air guiding mechanism 20 of an air outlet assembly 100 is disposed near an air outlet 11, the air guiding mechanism 20 has an outwardly convex air guiding curved surface 21, and the air guiding curved surface 21 can contact with an air flow blown out from the air outlet 11 to generate a coanda effect. Meanwhile, the air guide curved surface 21 is provided with the protrusion 22, so that the air flow can be separated along the protrusion 22 and blown out after contacting the protrusion 22. In addition, the air guide mechanism 20 can rotate relative to the air outlet 11, and the position of the air guide mechanism 20 or the position of the protrusion 22 can be adjusted, so that the air flow can be separated in different directions and blown to the downstream, and the purpose of adjusting the air direction is achieved.

The embodiment of the application provides an air outlet assembly 100, including air outlet 11 and air guide mechanism 20, air guide mechanism 20 corresponds and closes on air outlet 11 and sets up, and air guide mechanism 20 has wind-guiding curved surface 21, and wind-guiding curved surface 21 is the surface of evagination, and when the air current blew out from air outlet 11 and blow to air guide mechanism 20 often, can flow along wind-guiding curved surface 21 of air guide mechanism 20, produces the coanda effect.

Further, the air outlet assembly 100 further includes a protrusion 22, the protrusion 22 is connected to the air guiding structure and disposed on the air guiding curved surface 21, and can protrude from the air guiding curved surface 21, that is, the protrusion 22 has a protruding state protruding toward the outward protruding direction of the air guiding curved surface 21. The air guiding mechanism 20 can guide the airflow at the air outlet 11 to flow along the air guiding curved surface 21, and can be separated from the air guiding mechanism 20 along the protrusion 22 to be output to a target direction.

In the embodiment of the present application, the air guiding mechanism 20 having the air guiding curved surface 21 and the protrusion 22 is correspondingly disposed at the air outlet 11, so that the air flow at the air outlet 11 can contact with the air guiding curved surface 21 of the air guiding mechanism 20, a coanda effect is generated, the air flow deflects along the surface of the air guiding mechanism 20, and finally, after contacting the protrusion 22, the air flow is separated from the protrusion 22 and blown out.

For the traditional mode of adopting the air guide grids, sharp edges exist in the air guide grids, the air flow is easy to generate at high speed, and the risk of larger noise exists. The air outlet assembly 100 in the embodiment of the present application utilizes the coanda effect to enable the air flow to flow along the smooth curved surface, the smooth air guiding curved surface 21 enables the air flow to flow more smoothly, and no sharp edge exists on the curved surface, so that a large noise can be prevented from being generated when the air flow contacts the air guiding curved surface 21. Meanwhile, the resistance of the flow path of the curved surface is small, and the high speed of local airflow cannot be generated.

In the above, the coanda effect is also called coanda effect or coanda effect, and fluid (water flow or air flow) tends to flow along the surface of a protruding object instead of deviating from the original flow direction. When there is surface friction (also known as fluid viscosity) between a fluid and the surface of an object over which it flows, the fluid flows along the surface of the object.

Specifically, when the air outlet direction is adjusted, the air outlet 11 of the blowing surface of the vehicle is adjusted in the up-down direction by the following two methods: (1) Most motorcycle types adopt the guide effect of grid blade to adjust, and this kind of air outlet 11 structure is complicated, and the existence of grid blade can increase the pipeline resistance, produces local air current high-speed, has the noise risk under big amount of wind. (2) The small part of the motorcycle type adopts two air flows with different wind directions to mix wind, and the wind direction is adjusted by adjusting the flow of the two air flows. The air outlet structure needs to design two air flow channels and a control mechanism for air distribution of two air flows, and has the problems of complex structure, difficult design, high cost and difficult accurate control of wind direction performance.

In view of this, the air outlet assembly 100 in the embodiment of the present application adopts the rotatable air guiding mechanism 20, or adopts any one of the movable protrusions 22, or two of them to be combined, so as to implement accurate control of the wind direction.

Referring to fig. 6 to 9, in some embodiments, the protrusion 22 is movably connected to the wind guiding mechanism 20, and has a protruding state and a receiving state, in the protruding state (as shown in fig. 7 to 9), the protrusion 22 protrudes from the wind guiding curved surface 21; in the stored state (as shown in fig. 6), the projection 22 is flush with the air guiding curved surface 21. Alternatively, in the storage state, the protrusion 22 is spliced with the wind guide curved surface 21 to form a smooth curved surface. The movable connection mode of the protrusion 22 and the air guiding mechanism 20 includes, but is not limited to, a rotating connection and a sliding connection. The protrusion 22 can be connected with the wind guiding structure in a rotating or sliding manner, so that the protruding state and the accommodating state can be switched. When the protrusion 22 protrudes from the air guiding curved surface 21, the air flow is blocked by the protrusion 22 and can flow to the external space along the protrusion 22 after being separated from the air guiding curved surface 21. When the protrusion 22 is in the storage state, the protrusion 22 does not protrude from the air guiding curved surface 21, but is flush with the air guiding curved surface 21 through one surface thereof, for example, the two are spliced together to form a complete and smooth curved surface, and the air flow can generate a coanda effect on the air guiding curved surface 21 and the protrusion 22 and separate from the edge of the air guiding curved surface 21 or other protruding structures.

When the protrusion 22 is movably connected with the air guide mechanism 20, the protrusion 22 can be in a storage state, so that the air guide curved surface 21 and the protrusion 22 jointly form a relatively neat or smooth curved surface, and further the air flow is separated from the edge of the air guide curved surface; in one embodiment, the projections 22 may thus be hidden from impact damage during transport; meanwhile, when the air outlet 11 is not exhausted, the protrusions 22 are stored to reduce dust accumulation at corners. When the protrusion 22 is in a protruding state, the function of separating the air flow from the protrusion can be realized. The projection 22 can be freely switched between the storage state and the projection state, the use mode is more flexible, and the control of the air flow guiding can be responded more quickly.

In order to more conveniently accommodate the protrusion 22, the air guide mechanism 20 is further provided with an accommodating cavity 24, and an opening of the accommodating cavity 24 penetrates through the air guide curved surface 21; in the storage state, the projection 22 is stored in the storage cavity 24; in the protruding state, the projection 22 protrudes at least partially out of the receiving cavity 24 from the opening of the receiving cavity 24. The accommodating cavity 24 is arranged, so that the protrusion 22 can be hidden inside the air guide mechanism 20, and the air guide mechanism 20 can form a complete air guide curved surface 21. And, in the state of accomodating, be favorable to overall structure's compactness. Of course, in other embodiments, the housing cavity 24 may not be provided in the air guide mechanism 20, and the protrusion 22 may be provided to avoid the air guide curved surface 21 in the housed state, for example, may be hidden on the back surface of the air guide curved surface 21.

The shape of the receiving cavity 24 can be substantially matched with the protrusion 22, namely, the receiving cavity can just receive the protrusion 22, which is beneficial to the reasonable utilization of space and is more compact in structure. For example, if the protrusion 22 has a square shape, the receiving cavity 24 has a square shape matching the protrusion.

The receiving chamber 24 may have a groove structure in which one side is closed and the other side is opened, or the receiving chamber 24 may have a through hole structure in which both sides are penetrated. In some embodiments, the air guide mechanism 20 is cylindrical, and an outer peripheral surface of the air guide mechanism 20 forms an air guide curved surface 21. The housing cavity 24 penetrates the outer circumferential surface and the inner circumferential surface of the air guide mechanism 20; in the stored state, the projection 22 is spliced with the air guide mechanism 20 to form a completely bent cylinder, and at this time, one side surface of the projection 22 is flush with the outer peripheral surface of the air guide mechanism 20, and the other side surface of the projection 22 is flush with the inner peripheral surface of the air guide mechanism 20.

Note that, in the stored state, the protrusion 22 is flush with the air guiding curved surface 21, which means that the protrusion 22 does not protrude from the air guiding curved surface 21, and one surface of the protrusion 22 is flush with the air guiding curved surface 21.

In other embodiments, in the accommodated state, the protrusion 22 may not be flush with the inner circumferential surface of the wind guiding structure, for example, the protrusion 22 may protrude from the inner circumferential surface, or the protrusion 22 neither protrudes from the inner circumferential surface nor is flush with the inner circumferential surface, but is hidden in the accommodating cavity 24.

The shape of the wind guiding mechanism 20 includes, but is not limited to, a cylindrical shape, a semi-cylindrical shape, a half-cylindrical shape, a square-cylindrical shape, and the like.

Since the air flow flows along the wire of the air guiding curved surface 21, that is, along the extending direction of the air guiding curved surface 21, and the protrusion 22 plays a role of blocking and guiding the flow of the air flow, in order to better guide all the air flow, in some embodiments, the protrusion 22 extends along the generatrix of the air guiding curved surface 21 to form a long strip shape. The curved surface figure can be regarded as the orbit when the movable line moves, and the movable line forming the curved surface is called as a generatrix. The wires controlling the movement of the bus bars are then called the wires.

The cross section of the protrusion 22 may be square, semicircular, triangular or trapezoidal, and the cross section is perpendicular to the extending direction, i.e., the length direction, of the protrusion 22. The shape of the protrusion 22 is not limited as long as the protrusion can protrude on the air guiding curved surface 21 and allow the air flow to escape from the protrusion 22.

Note that, when the protrusion 22 and the air guiding curved surface 21 are joined to form a smooth curved surface in the stored state, the surface of the protrusion 22 flush with the air guiding curved surface 21 is a single curved surface. Since the width of the protrusion 22 (the width in the circumferential direction of the air guiding curved surface 21) is extremely small compared to the entire air guiding curved surface 21, the curved surface can be regarded as a flat surface, and therefore, when the cross section of the protrusion 22 is square or trapezoidal, the curved surface can be regarded as a flat surface, that is, the cross section of the protrusion 22 can be substantially square or trapezoidal.

Further, the air outlet assembly further comprises an adjusting mechanism (not shown), and the adjusting mechanism is connected with the protrusion 22 and is used for adjusting the protruding height H of the protrusion 22 on the air guiding curved surface 21. The adjusting mechanism may include a driving member such as a motor or an air cylinder that can automatically adjust the protrusion height H of the protrusion 22. When the adjusting mechanism receives a control signal sent by the controller, the projection height H of the projection 22 can be automatically adjusted, and the degree of automation is high. Of course, the adjusting mechanism may also be a mechanical manual adjusting mechanism, such as a knob, a dial block, or a hand wheel, and the user may manually rotate the knob, slide the dial block up and down, or shake the hand wheel to adjust the protrusion height H of the protrusion 22.

The adjusting mechanism can be arranged in the air outlet casing 10, and can be hidden in the air outlet casing 10 for the motor. For the manual adjusting mechanism, a portion thereof for a user to act may be exposed outside the air outlet housing 10.

The protrusions 22 with different heights have different guiding effects on the air flow, and the air flow is output to different directions when the air flow is separated from the protrusions 22 with different heights, and the heights of the output directions are different. Therefore, the air flow of the air outlet 11 can be guided to separate along different directions by adjusting the protruding height of the protrusion 22, thereby achieving the purpose of adjusting the wind direction.

Referring to fig. 5, in some embodiments, the protrusion height H of the protrusion 22 on the wind guiding curved surface 21 is greater than or equal to 10mm and less than or equal to 20mm. If the protrusion height H of the protrusion 22 is too large, the airflow will be blocked greatly, which is not favorable for smooth airflow. If the protrusion height H of the protrusion 22 is too small, the air flow easily crosses the protrusion 22 and continues to flow along the air guiding curved surface 21, i.e., the air flow cannot completely escape at the protrusion 22. Therefore, in the present embodiment, the protrusion height H of the protrusion 22 is limited to 10mm to 20mm, which can avoid the above-mentioned problem. Illustratively, the protrusion height of the protrusion 22 may be 11mm, 13mm, 16mm, and so on.

The protrusion height H of the protrusion 22 refers to a vertical distance between the top of the protrusion 22 and the wind guide curved surface 21.

Referring to fig. 6 to 9 again, a plurality of protrusions 22 are further disposed on the air guiding mechanism 20, and the plurality of protrusions 22 are distributed at intervals along the direction of the wires of the air guiding curved surface 21. Because the distribution positions of the protrusions 22 on the air guide curved surface 21 are different, the separation directions of the air flow when the air flow is separated from different protrusions 22 are also different, so that the outflow direction of the air flow can be adjusted by adjusting any one of the protrusions 22 to be in a convex state and the other protrusions 22 to be in a storage state, that is, the air flow at the air outlet 11 can be guided to flow along the air guide curved surface 21 and output to a target direction through different protrusions 22, and the purpose of adjusting the wind direction is achieved.

As shown in fig. 7, when the upper projection 22 is projected outward, the air flow can be guided to escape from the projection 22 at the upper position, and the escape direction of the air flow is inclined upward, the air flow can be blown toward a higher position in the room.

As shown in fig. 8, when the middle protrusion 22 protrudes outward, the escape direction of the air flow is slightly inclined downward, and the angle between the escape direction of the air flow and the horizontal direction is small.

As shown in fig. 9, when the lower protrusion 22 protrudes outward, the airflow separation direction is inclined downward at a large angle, and the angle between the airflow separation direction and the horizontal direction is large, so that the airflow can be blown to a lower position in the room.

The movement of the protrusion 22 relative to the air guiding mechanism 20 can be achieved by manual adjustment or by driving structure such as a motor. In some embodiments, the protrusion 22 may be manually pushed or pulled out of the cavity 24 or pushed into the cavity 24. In other embodiments, a motor or other driving structure may be provided to drive the protrusion 22 to move, so that the protrusion 22 may be received in the receiving cavity 24 or protrude from the wind guiding curved surface 21.

In other embodiments, the protrusion 22 may also be integrally formed with the air guiding structure, and the protrusion 22 is fixed relative to the air guiding structure.

Further, the protruding height of the protrusion 22 on the air guiding curved surface 21 can be adjusted, that is, the protrusion 22 is movably connected with the duct mechanism 20, so that the protruding height of the protrusion 22 on the air guiding curved surface 21 can be adjusted, and the separation angle of the air flow can be changed.

In some embodiments, the air guiding mechanism 20 can rotate around a rotation axis relative to the air outlet 11, a generatrix of the curved air guiding surface 21 is parallel to the rotation axis, and the curved air guiding surface 21 is disposed around the rotation axis, and the curved air guiding surface 21 is a convex surface relative to the rotation axis of the air guiding mechanism 20.

As shown in fig. 2 to 4, when the wind guiding mechanism 20 rotates to different angles, so that the vertical distance between the protrusion 22 and the wind outlet 11 on the wind guiding mechanism changes, the wind guiding mechanism can guide the airflow to be separated from different angles and blown out, thereby achieving the purpose of adjusting the wind direction. Of course, as for the wind guiding mechanism 20 shown in fig. 6 to 9, the wind guiding mechanism 20 may also be rotatably arranged, and cooperate with the plurality of movable protrusions 22 to adjust the wind direction together, so as to achieve the purpose of precise and continuous adjustment.

When the air guide mechanism 20 rotates around the rotation axis, the air flow at the air outlet 11 can be guided to flow along the air guide curved surface 21, and then the air flow is separated from the protrusion 22 and output to a target direction. Adopt the air guide mechanism 20 who has protrusion wind-guiding curved surface 21, have simple structure, adjust convenient effect, only need rotate air guide mechanism 20, the height and the angle at protrusion 22 place on the transform wind-guiding curved surface 21 can make the air current break away from along different directions, blows to the direction that the user wanted, target direction, reaches the purpose of adjusting the wind direction, realizes continuous accurate air current direction and adjusts.

For the air guide grille, the air guide mode is not perfect linear adjustment, but proportional linear adjustment, so the continuity of air flow adjustment is poor. However, the rotation of wind-guiding curved surface 21 formula is adjusted in the embodiment of this application, wind-guiding curved surface 21 changes several degrees, can drive arch 22 and rotate together, the air current also can follow wind-guiding curved surface 21 and carry out curved rotation simultaneously, its regulative mode is more gentle and smooth, the continuity of air current preferred, the smooth surface that the air current can directly follow wind-guiding curved surface 21 gets into simultaneously, along the protruding 22 outflow on the wind-guiding curved surface 21, so there is not sharp-pointed edge on the flow path of air current, produced noise is lower.

In some embodiments, the wind guiding surface 21 is disposed around the rotation axis. In this embodiment, the generatrix of the air guiding curved surface 21 is parallel to the rotation axis, so that the air flow is in an arc shape along the bending direction of the air guiding curved surface 21. Optionally, the axis of the wind guiding curved surface 21 coincides with the rotation axis, which is beneficial to more accurately and more simply controlling the flowing direction of the airflow.

In some embodiments, the wind guiding curved surface 21 may include a plurality of arc-shaped surfaces, and the plurality of arc-shaped surfaces are sequentially and smoothly connected. Optionally, the radii of the arc-shaped surfaces are different, that is, the radius of any one arc-shaped surface is different from the radii of the other arc-shaped surfaces, so that the air guiding curved surface 21 is a surface with a varying curvature. The arc surface can be a circular arc surface or an elliptic arc surface.

The shape of the air outlet 11 is various, and the air outlet 11 can be a rectangular opening, a square opening, a trapezoid opening, an oval opening, a circular opening, and the like. Illustratively, the outlet 11 is elongated. Taking the vertical and horizontal directions as an example, as shown in the figure, the length direction of the outlet 11 is along the horizontal direction, and the width direction of the outlet 11 is along the vertical direction.

The air guide mechanism 20 may have various shapes, and the air guide mechanism 20 may be a long strip or the air guide mechanism 20 may have a length dimension and a width dimension close to each other. The cross section of the air guiding mechanism 20 may be close to a trapezoid, a sector, a circle, or the like.

In some embodiments, the air outlet 11 and the air guiding mechanism 20 are both long strips, and the length direction of the air guiding mechanism 20, the length direction of the air outlet 11, and the rotation axis are parallel. The generating line direction of the air guiding curved surface 21 is along the longitudinal direction of the air guiding mechanism 20.

The parallelism in the embodiment of the present application means parallel or substantially close to parallel, that is, the length direction of the air guiding mechanism 20, the length direction of the air outlet 11, and the rotation axis are completely parallel or close to parallel.

Optionally, the diameter of the air guiding curved surface 21 is greater than or equal to the width of the air outlet 11, so that the diameter of the air guiding curved surface 21 is larger than the width of the air outlet 11, and a relatively obvious coanda effect can be generated.

Illustratively, the diameter of the air guiding curved surface 21 is greater than or equal to 100mm; and/or the width of the air outlet 11 is more than or equal to 10mm and less than or equal to 50mm. The diameter of the air guide curved surface 21 is larger than or equal to 100mm, so that the curvature of the air guide curved surface 21 is ensured to be smaller, and a more obvious coanda effect can be generated. Meanwhile, the air guide curved surface 21 of the size is matched with the air outlet 11 with the width being more than or equal to 10mm and less than or equal to 50mm, the adaptation degree of the air guide curved surface and the air outlet 11 is high, and the air guide curved surface can better guide the air flow blown out from the air outlet 11 to flow out.

In some embodiments, the orthographic projection of the air guiding mechanism 20 on the air outlet 11 only partially blocks the air outlet 11. Optionally, the wind guide curved surface 21 partially blocks the wind outlet 11. Therefore, the air guide mechanism 20 can be prevented from completely shielding the air outlet 11 to influence the air guide effect. When the air guiding curved surface 21 partially blocks the air outlet 11, no matter the air guiding curved surface 21 is rotated to any position, a gap is formed between the air guiding curved surface 21 and the air outlet 11, and the gap can guide the air flow to flow out.

Illustratively, the outlet 11 has a first side edge 111 and a second side edge 112 opposite to each other, and the first side edge 111 and the second side edge 112 extend along the rotation axis respectively. One side of the air guiding mechanism 20 is located between the first side edge 111 and the second side edge 112, and the other side of the air guiding mechanism 20 is located on the side of the first side edge 111 away from the second side edge 112.

Taking the vertical and horizontal directions as an example, the first side edge 111 and the second side edge 112 both extend in the horizontal direction, the first side edge 111 and the second side edge 112 are long sides of the outlet 11, the first side edge 111 is a lower side edge of the outlet 11, and the second side edge 112 is an upper side edge of the outlet 11. Taking the wind guide mechanism 20 as a cylindrical shape as an example, the upper side of the wind guide mechanism 20 is located between the upper and lower side edges of the outlet 11, and the lower side of the wind guide mechanism is located below the lower side edge of the outlet 11. The top point of the air guiding curved surface 21 is located between the upper and lower side edges of the air outlet 11 and does not protrude from the upper side edge of the air outlet 11, so that the blocking of the outflow of the air flow can be avoided.

The length of the air guide curved surface 21 along the rotation axis is greater than or equal to the length of the air outlet 11 along the rotation axis. That is, both ends of the air outlet 11 are flush with both ends of the air guiding curved surface 21, or both ends of the air outlet 11 are located between both ends of the air guiding curved surface 21, so that all the air flows flowing out of the air outlet 11 can be guided to the target direction by the air guiding curved surface 21 of the air guiding mechanism 20.

Further, air-out subassembly 100 includes air-out casing 10, and air-out casing 10 is provided with air outlet 11. The air outlet casing 10 may be a plastic part or a metal part, and for example, the air outlet casing 10 is a plastic part, which is low in cost and light in weight. Specifically, the air outlet housing 10 is provided with an air outlet channel, and the air outlet channel penetrates through one end of the air outlet housing 10 to form an air outlet 11.

In some embodiments, the air guiding mechanism 20 is disposed outside the air outlet 11. In order to ensure the smoothness of the rotation of the air guiding mechanism 20 and avoid the edge friction between the air guiding mechanism 20 and the air outlet 11, the air guiding mechanism 20 and the air outlet 11 are optionally arranged at an interval with a small gap therebetween.

Alternatively, in other embodiments, the air guiding mechanism 20 is at least partially disposed within the air outlet 11. In this embodiment, the air guiding mechanism 20 may be entirely located in the air outlet 11, or the air guiding mechanism 20 is only partially located in the air outlet 11, as long as the air flow can generate an obvious coanda effect with the air guiding curved surface 21 of the air guiding mechanism 20. Optionally, a groove or a through hole is formed in a hole wall of the air outlet channel, the air guiding mechanism 20 is at least partially located in the groove or the through hole, and another portion protrudes out of the air outlet channel.

In the above, the air guide mechanism 20 is disposed inside the outlet 11 or outside the outlet 11, and the air guide mechanism 20 may be located on the path of the air flow blown out from the outlet 11, so that the air flow blown out from the outlet 11 can contact the air guide curved surface 21 of the air guide mechanism 20.

Further, the air outlet assembly 100 further includes a driving member (not shown) connected to the air guiding mechanism 20, and the driving member is configured to drive the air guiding mechanism 20 to rotate. The driving piece can include the motor, and the drive mode of motor is adjusted accurately, carries out electrical control to wind guiding mechanism 20 through the motor, and drive wind guiding mechanism 20 rotates. Alternatively, the driving member is a manual adjusting member, for example, the driving member may include a knob, the knob is fixed to one end of the air guiding mechanism 20, and the rotation of the air guiding mechanism 20 may be achieved by manually rotating the knob. The manual adjustment mode is low in cost.

In this embodiment, the connection manner between the driving member and the air guiding mechanism 20 is not limited. For example, taking a motor as an example, the motor may be connected to the wind guiding mechanism 20 through a worm gear or a gear set, or a gear and a rack, or the motor may be directly connected to the wind guiding mechanism 20.

The driving element may be disposed inside the air outlet casing 10, or the driving element may also protrude outside the air outlet casing 10. Taking the motor as an example, the motor can be hidden inside the air outlet casing 10, reducing the collision between the motor and other structures, and simultaneously avoiding the motor from being exposed outside to affect the appearance. Taking the knob as an example, the knob is exposed outside the air outlet casing 10 for convenient operation.

In some embodiments, the opposite ends of the air guiding mechanism 20 are respectively rotatably connected to the air outlet housing 10. Specifically, taking the air guiding mechanism 20 disposed outside the air outlet 11 as an example, two supporting seats may be disposed on the outer surface of the air outlet casing 10, a rotating hole or a rotating shaft is disposed on the supporting seats, two opposite ends of the air guiding mechanism 20 are correspondingly disposed with the rotating shaft or the rotating hole, and the air guiding mechanism 20 and the supporting seats are rotatably connected through the rotating matching of the rotating shaft and the rotating hole.

The air guide mechanism 20 in the embodiment of the application can realize the adjustment of the wind direction by protruding the protrusions 22 at different positions from the air guide curved surface 21; the position of the projection 22 can be changed by utilizing the rotatability of the air guide mechanism 20, so that the wind direction can be adjusted. Through the combination of the two modes, the air guide mechanism 20 has a large air direction adjusting range, and can quickly realize the adjustment of air with different directions.
