DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The embodiments of the present invention are described in detail below with reference to the accompanying drawings. According to an aspect of the invention, there is provided an air guiding device, as shown in Figures 1 to 3, the air guiding device comprising: a mounting plate 10; a plurality of blades 20 disposed on the mounting plate 10; the connecting rod 30, comprising a body 31 and a guiding protrusion 32 disposed on the body 31, the body 31 is connected to the plurality of blades 20; a guiding plate 40, a limiting opening 41 is defined in the guiding plate 40, and a part of the guiding protrusion 32 is disposed in the limiting opening 41 The guide protrusion 32 is slidable in the limiting opening 41 along the extending direction of the limiting opening 41 by the external force, and the edge of the limiting opening 41 contacting the guiding protrusion 32 is smoothly deformed. Surface. The plurality of blades 20 of the air guiding device of the present invention are connected by the connecting rod 30, and the blade 20 rotates with the movement of the connecting rod 30, so that the person can adjust the wind direction by moving the connecting rod 30, and the guiding projection on the connecting rod 30 32 is positioned by the limiting opening 41, and the edge of the limiting opening 41 contacting the guiding protrusion 32 has a smoothly deformed curved surface, so that the magnitude and direction of the force received by the guiding protrusion 32 when moving in the limiting opening 41 are not A sudden change occurs, and the guiding projection 32 can smoothly move in the limiting opening 41 under the action of an external force, which causes the guiding link 32 to smoothly rub between the guiding projection 32 and the limiting opening 41, compared to the zigzag shape. In the positioning structure, the resistance of the moving chuck is smaller, the guiding projection 32 is easier to slide, and since the guiding projection 32 does not suddenly hit the limiting opening 41 when sliding, the sliding noise is smaller. Preferably, the shape of the limiting opening 41 is curved. The guiding protrusion 32 can smoothly slide in the arc-shaped limiting opening 41, and the guiding protrusion 32 realizes self-locking in the arc-shaped limiting opening 41 by friction. Alternatively, the limit opening 41 is wavy. The undulating limiting opening 41 is not a zigzag shape in the prior art, and the direction of the force of the guiding projection 32 when moving in the undulating limiting opening is uniformly changed, and does not occur as in the zigzag shape. The direction of the force caused by the movement in the bayonet is abrupt, so that the guiding projection 32 can smoothly move in the limiting opening 41 under the action of the external force, and can be more stably fixed at the position of the trough of the limiting opening 41. Compared with the zigzag-shaped bayonet, the guide projection 32 can slide more smoothly in the wave-shaped limit opening 41, the friction is small, and the noise generated is also weak. Preferably, the guide projection 32 can be self-locked at any position in the limit opening 41. In the prior art, the chuck can only be fixed to the valley portion of the zigzag bayonet, and the guide bump 32 of the present invention can be self-locked at any position in the limit opening 41, providing more options. The direction of the air supply. Preferably, the maximum outer diameter of the guide projection 32 is larger than the width of the limit opening 41 by 0.2 mm to 0.8 mm. In this way, the guiding protrusion 32 can be clamped in the limiting opening 41 at the same time, realize self-locking, does not move freely, and ensures the direction of the blade 20 is stable. The difference between the maximum outer diameter of the guide projection 32 and the width of the limit opening 41 is determined according to the material of the guide plate 40. If the guide plate 40 is made of a material that is more easily deformed, the maximum of the guide projection 32 is obtained. The difference between the outer diameter and the width of the limit opening 41 can be large, and if the guide plate 40 is made of a material that is not easily deformed, the difference is small. Preferably, the guiding protrusion 32 has an interference of about 0.3 mm between the limiting opening 41 and the limiting opening 41 to achieve self-locking, and the interference amount cannot be too large, otherwise the resistance is too large, and the guiding protrusion 32 is inconvenient. Sliding. Preferably, as shown in FIGS. 1 and 2, the guide projection 32 is provided at one end of the body 31. The guiding protrusion 32 and the guiding plate 40 can be disposed outside the air outlet, which can make the air outlet more compact. Preferably, the link 30 further includes a handle 33 that is disposed on the body 31 and that extends away from the blade 20. Preferably, the guide plate 40 further includes a first auxiliary opening 42 for assisting expansion of the limit opening 41. Preferably, the guide plate 40 further includes a second auxiliary opening 43 for assisting the expansion of the limiting opening 41. The first auxiliary opening 42 is disposed at one side of the limiting opening 41, and the second auxiliary opening 43 is disposed at the limiting opening 41. The other side. Since the diameter of the guiding protrusion 32 is larger than the width of the limiting opening 41, the guiding protrusion 32 or the limiting opening 41 may be deformed when the guiding protrusion 32 moves in the limiting opening 41, so that the guiding protrusion 32 is more convenient. The movement of the limit opening 41 provides an auxiliary opening in the guide plate 40 to assist in the deformation expansion of the limit opening 41. Preferably, as shown in FIG. 2, the limit opening 41 has an arc shape, and the first auxiliary opening 42 and the second auxiliary opening 43 have the same curvature as the limit opening 41. If the limiting opening 41 is wavy, the first auxiliary opening 42 and the second auxiliary opening 43 may be curved or may have a wave shape corresponding to the limiting opening 41. Preferably, the first auxiliary opening 42 is disposed corresponding to the central portion of the limiting opening 41, and the second auxiliary opening 43 is disposed corresponding to both end portions of the limiting opening 41. Since the direction of the force is different when the guiding protrusion 32 moves in the limiting opening 41, when the guiding protrusion 32 moves to the middle of the limiting opening 41, the limiting opening 41 is deformed toward the center of the arc, so the first auxiliary opening 42 is opened on the side of the limit opening 41 near the center of the circle; when the guide protrusion 32 moves to both ends of the limit opening 41, the limit opening 41 needs to be deformed toward the side far from the center of the circle, so the second auxiliary opening 43 is opened. On the side of the limit opening 41 away from the center of the circle. If the auxiliary opening is opened only on one side, then The resistance to the convex portion 32 moving in the middle or the end of the limiting opening 41 is large, and it is not easy to be moved; if the auxiliary opening completely corresponding to the limiting opening 41 is simultaneously opened on both sides, the guiding projection 32 is at the limit. The resistance at the middle or end of the opening 41 is too small to form a self-locking. However, the auxiliary opening may be opened only on one side of the limiting opening 41 or the auxiliary opening may be opened on both sides of the limiting opening, but the auxiliary opening 41 is deformed as shown in FIG. Excellent design. Preferably, both ends of the first auxiliary opening 42 partially overlap each of the second auxiliary openings 43 in the extending direction of the limiting opening 41, and the first auxiliary opening 42 and the second auxiliary opening 43 overlap each other by 8 to 15 degrees. The coincidence area is to facilitate the deformation of the limit opening 41 when the guide projection 32 is moved to the corresponding position. Preferably, the center of the limit opening 41 has a radius of 23 mm to 27 mm. Preferably, as shown in FIG. 3, the guide projection 32 includes a rod body 321 and a flange at the end of the rod body 321

322, the maximum outer diameter of the flange 322 is larger than the diameter of the rod 321 , and the flange 322 passes through the limiting opening 41. The flange 322 prevents the guide projection 32 from coming off the limit opening 41, thereby ensuring that the blade 20 does not get out of control. Preferably, the diameter of one end of the flange 322 away from the rod body 321 is smaller than the width of the limit opening 41. One end of the flange 322 is tapered so that the limit opening 41 can be more easily squeezed to fit the flange 322 into the limit opening 41. Preferably, a groove 323 is formed in the flange 322 along the axial direction of the guide projection 32. Preferably, the groove 323 extends to the middle of the rod body 321. When the guide protrusion 32 is mounted in the limit opening 41, if the flange 322 is to be squeezed inside and the flange is pushed through the limit opening 41, the groove 323 is opened to help the flange to deform, passing through the limit opening. 41 The rear flange 322 rebounds. When disassembling, the flange 322 is first pressed inwardly, and the flange 322 is withdrawn from the limiting opening 41. In addition, the recess 323 can also assist the deformation of the rod 321 to move in the limit opening 41.
