Wherein, the second connecting rod 3 is arranged on the upper end of the motor 4, when the motor 4 is running, the output shaft of the motor 4 will drive the second connecting rod 3 to swing, and the second connecting rod 3 will further drive the first connecting rod connected to it in rotation 2, the swing of the first connecting rod 2 drives the swing leaf 1 which is connected to it in rotation.

In an optional embodiment, the air conditioner swing mechanism further includes a motor bracket 9 on which the motor 4 is mounted. The setting of the motor support 9 is to play a role of fixed support for the motor 4, and the motor support 9 can be fixedly installed with the housing of the air conditioner by means of screw connection.

As shown in FIG. 3 , in an optional embodiment, the motor bracket 9 defines a mounting slot 93 along the horizontal direction, and the motor 4 is installed in the mounting slot 93 . The cross-section of the installation groove 93 can be semicircular or other shapes, as long as it can fix and support the motor 4, no specific limitation is imposed. The setting of the motor support 9 is mainly to connect the motor 4 with the housing of the air conditioner, so as to realize the installation of the motor 4. An installation groove 93 is provided on the motor support 9 to provide an installation space for the motor 4. At the same time, the upper end of the installation groove 93 The opening also gives the motor 4 a certain heat dissipation space, which is beneficial to the heat dissipation of the motor 4 .

The limiting structure 11 provided by the embodiment of the present invention has a simpler structure, is convenient to use, and has obvious effects. It effectively avoids the deviation of the forward and reverse angles when the output shaft of the motor 4 rotates during long-term use, resulting in inconsistent left and right swing angles of the second connecting rod 3, which ultimately affects the left and right swing angles of the swing blade 1. The "left and right" here describes the swinging direction of the second connecting rod 3 from the view direction in Fig. 6-1 to Fig. 6-3. When the viewing directions are different, the description of the swinging direction of the second connecting rod 3 will be different.

In an optional embodiment, the limiting structure 11 is slidably disposed on both sides of the mounting groove 93 , and slides with the output shaft of the motor 4 as a line of symmetry. The sliding setting of the limit structure 11 is used to adjust the distance between the two limit structures 11, so that the swing range of the second connecting rod 3 can be precisely controlled, and the motor 4 can be adjusted according to actual needs. Under the condition of rotating speed, the swing range of the connecting rod 3 at the bottom is properly adjusted, the first connecting rod 2 is driven by the second connecting rod 3, and the swing blade 1 is driven by the first connecting rod 2 to realize the adjustment of the swinging angle. Optionally, as shown in FIG. 4 , slideways 921 are provided on the groove edges on both sides of the installation groove 93 respectively, and elastic protrusions are set at set intervals on the inner wall of the slideway 921 . The corresponding projections of the slideways 921 are used to adjust the distance between the two limiting structures 11 .

Specifically, when the position-limiting structure 11 slides left and right along the chute, the protrusion at the bottom of the position-limiting structure 11 will collide with the elastic protrusion to realize the position fixing of the position-limiting structure 11. Since it is an elastic protrusion, when When it is necessary to slide left and right again, as long as the force is used to slide, the limiting structure 11 will squeeze the elastic projections to slide freely. Wherein, the setting distance depends on the actual situation, and can be selected as 5mm, 10mm or others. By adjusting the position of the limit structure 11, the swing angle of the second connecting rod 3 driven by the output shaft of the motor 3 is limited, so that the second connecting rod 3 drives the first connecting rod 2 to swing, and the first connecting rod 2 Drive the swing leaf 1 to swing, and finally realize the adjustment of the left and right swing angle of the swing leaf 1, so that the swing leaf 1 can have different maximum left and right swing angles, bringing users more experience and effects.
