The second end of the rotating shaft 21 is connected with the connecting disc 22, and the rotating shaft 21 and the connecting disc 22 are of an integral structure. In batch production, the blade body 1, the rotating shaft 21 and the connecting disc 22 are cast in an integrated manner, the material is plastic, the integral strength of the integrated structure is higher, the service life is longer, the production efficiency is higher, secondary machine tool machining is avoided, and the production cost is saved.

In some embodiments, as shown in fig. 1, the first end of the connecting arm 23 is fixedly connected to the connecting disc 22 in a snap-fit manner, and the connecting arm 23 cannot rotate around the connecting disc 22 relatively, so that when the connecting arm 23 rotates, the connecting disc 22 is driven to rotate together. The second end of the connecting arm 23 extends along the radial direction of the connecting disc 22, the second end of the connecting arm 23 is provided with a connector 233, and the connector 233 is connected with the wind sweeping component in a buckling mode and can rotate around the wind sweeping component relatively for transmitting rotary power.

As shown in fig. 2, the wind sweeping assembly of the embodiment of the second aspect of the present invention includes a mounting frame 3 and a driving member 4, the wind sweeping blades are rotatably mounted on the mounting frame 3, the wind sweeping blades are arranged along the length direction of the mounting frame 3 at intervals, and the interval setting is to satisfy that the wind sweeping blades do not interfere in the rotating process. The driving piece 4 is connected with the wind sweeping blade to drive the wind sweeping blade to rotate.

The decorative portion 32 has a first end and a second end in the longitudinal direction thereof, and the second end of the wind sweeping portion 31 is connected to the first end of the decorative portion 32.

As shown in fig. 2 to 5, in some embodiments, the air inlet end 11 is curved toward the second end of the air sweep portion 31, the air outlet end 12 is curved toward the first end of the air sweep portion 31, the shape of the blade body 1 is similar to an S shape, and the air inlet end 11 and the air outlet end 12 are curved in the same range and are symmetrical in center. The bending amplitude of the air inlet end 11 and the air outlet end 12 is not unique, and the bending amplitude can be reasonably set according to actual requirements and a wind sweeping range.

As shown in fig. 2 and 6, in some embodiments, the partial blades in the wind sweeping assembly are wind sweeping blades, the wind sweeping blades are at least two, and at least two wind sweeping blades are arranged near the first end of the wind sweeping part 31. In order to maintain the uniformity of the wind sweeping blades, all the wind sweeping blades can be arranged in an arc structure, but the right wind sweeping angle is lost. To this problem, can sweep the wind blade and sweep wind limit angle about setting up as different angles, left air-out limit angle is less than right air-out limit angle.

It should be noted that the left-side wind sweeping angle is usually limited by the structure, and the problem of small left-side wind sweeping range cannot be solved by increasing the left-side wind sweeping angle in the conventional case. Therefore, if one part of the wind sweeping blades adopts arc-shaped blades and the other part adopts straight blades, the mode of mixing the blades at least ensures that at least the first two wind sweeping blades at the first end on the left side of the wind sweeping part 31 are arc-shaped blades.

As shown in fig. 1 and fig. 3 to 5, in some embodiments, the blade body 1 has a first wind guide surface 14 and a second wind guide surface 15 which are opposite to each other, the blade body 1 is rotatable between a first wind outlet position (a position shown in fig. 3) and a second wind outlet position (a position shown in fig. 5), so as to achieve wind blowing in different angle ranges, and the blade body 1 can stop rotating at any position between the first wind outlet position and the second wind outlet position, so as to achieve fixed-angle wind blowing.

As shown in fig. 1 and 3, in some embodiments, the driving member 4 includes a connecting rod 41 and a motor 42, the connecting rod 41 is provided with a plurality of connecting holes 411 arranged at intervals along a length direction thereof, a connecting head 233 of the wind sweeping blade is rotatably installed in the connecting hole 411, when the connecting rod 41 moves left and right, the wind sweeping blade is driven to rotate, and a rotation angle of the wind sweeping blade depends on a displacement amount of the connecting rod 41 moving left and right. The motor 42 (not shown) is connected to one end of the connecting rod 41 to provide power for the movement of the connecting rod 41, and the motor 42 is hidden under the decoration part 32 to avoid being exposed outside and affecting the appearance.

As shown in fig. 3-5, in some embodiments, the blade body 1 further has a front air outlet position (shown in fig. 4), in which a connection line between the air inlet end 11 and the air outlet end 12 is a reference line, the reference line is perpendicular to the length direction of the mounting frame 3, in the first air outlet position, an included angle between the connection line between the air inlet end 11 and the air outlet end 12 and the reference line is a °, and in the second air outlet position, an included angle between the connection line between the air inlet end 11 and the air outlet end 12 and the reference line is b °, where a < b, for example, a is 46 and b is 57.

It should be noted that when the blade body 1 is set to be a curved structure, the right side wind sweeping angle is lost, and when a is less than b, on one hand, the same wind sweeping range on the left and right sides can be realized, and on the other hand, because the link rod 41 is pushed for left wind sweeping and the link rod 41 is pulled for right wind sweeping, under the requirement of the same wind sweeping range, a smaller motor can be used.
