In order to increase the blowing range, more air outlets can be added, and a swing blade mechanism is set on each air outlet. However, since two swing blade mechanisms require two sets of motors to be independently controlled, the manufacturing cost and the use cost are increased. Utility Model Content

[0041] A double swing blade synchronization device, such as Figure 1 and Figure 2 As shown, it includes two swing blades 300, and the two swing blades 300 are respectively provided with a rotating shaft 412. In this embodiment, the swing blade 300 is a rectangular strip-shaped component, and the rotating shaft 412 is respectively provided at two ends of the swing blade 300 in the length direction, or penetrates the swing blade 300 in the length direction.

[0042] The double-swing blade synchronization device also includes a power source 500 that outputs a rotary motion to the outside, and an actuator that is transmission-connected between the power source 500 and the swing blade 300. In this embodiment, preferably, the actuator is configured to convert the rotary motion of the power source 500 into the rotational motion of the rotating shaft 412, so that the two swing blades 300 swing toward the same side or the two swing blades 300 swing toward opposite sides.

[0043] There is no limitation on the specific structure of the actuator for realizing the above-mentioned conversion movement. This embodiment provides a preferred implementation method, in which the actuator includes a rotating rod 401 , two first connecting rods 402 and two second connecting rods 403 .

[0044] The rotating rod 401 is a rod-shaped component, and the shape of the cross section of the rod-shaped component is not specifically limited. The cross section of the rod-shaped component can be rectangular, circular or annular. In this embodiment, the power source 500 is preferably a stepper motor, which is fixed to the carrier through the base 501. It can also be replaced by a servo motor or a common motor. The output shaft of the power source 500 is connected to the center of the rotating rod 401 so that the two ends of the rotating rod 401 have two swinging directions facing different directions according to the center.

[0045] In this embodiment, the two first connecting rods 402 are respectively hinged to the two ends of the rotating rod 401, the two second connecting rods 403 are respectively hinged to the two ends of the first connecting rod 402, and the other end of the second connecting rod 403 is connected to the rotating shaft 412. In one embodiment, the actuator further includes a transmission mechanism suitable for converting the swing of the second connecting rod 403 into the rotational motion of the rotating shaft 412, and two transmission mechanisms are provided. Each transmission mechanism includes a first gear 410 and a second gear 411, one end of the second connecting rod 403 is provided on the first gear 410, the second gear 411 is meshed with the first gear 410, and one end of the rotating shaft 412 is connected to the second gear 411.

[0046] refer to Figure 3 and Figure 4, the power source 500 outputs rotation, drives the rotating rod 401 to rotate, and the two ends of the rotating rod 401 swing, driving the first connecting rods 402 on both sides to retract inward or extend outward at the same time. The first connecting rod 402 can drive one end of the second connecting rod 403 to move together while moving. Since the other end of the second connecting rod 403 is fixedly set on the first gear 410, the range of the second connecting rod 403 swinging with the first connecting rod 402 is converted into the rotation of the first gear 410, which is transmitted from the first gear 410 to the second gear 411, and finally drives the rotating shaft 412 to rotate. In this embodiment, the radius of the first gear 410 is equal to the radius of the second gear 411. The swing range of the second connecting rod 403 is limited, which is converted into a limited rotation range of the first gear 410. By changing the radius of the first gear 410 and the second gear 411, the gear ratio is changed, so that the rotation range converted to the second gear 411 is larger, so that the swing range of the rotating shaft 412 and the swing blade 300 is larger. As an alternative embodiment, the other end of the second connecting rod 403 directly acts on the rotating shaft 412, and the swing of the second connecting rod 403 directly drives the rotating shaft 412 to swing within a certain range, thereby driving the swing blades 300 on the rotating shaft 412 to swing.

[0047] In this embodiment, the rotating shaft 412 is disposed at the midpoint of the swing blade 300, so that the swing blade 300 can swing in two directions along the midpoint position. The rotating shaft 412 is rotatably connected to the midpoint of the swing blade 300, so that the swing blade 300 can swing 0-90 degrees in two directions respectively, and the total adjustable range is 0-180 degrees, thereby increasing the blowing range.

[0048] This embodiment also provides a blowing device, referring to Figure 1 , at least includes a box body 100 and the above-mentioned double-swing blade synchronization device.

[0049] In this embodiment, the specific structure of the box 100 is not limited. Two air outlets 201 are provided on the box 100, and two swing blades 300 of the double swing blade synchronization device are respectively provided at the two air outlets 201. Preferably, the air outlets 201 extend along the length direction of the box 100 and are respectively provided on both sides in the width direction of the box 100; the swing blades 300 are suitable for swinging the airflow in the width direction of the box 100. With such a configuration, the space of the box 100 can be maximized, and the maximum blowing range can be obtained in the structure of the box 100.

[0050] There is no specific limitation on the specific application scenarios and application methods of the blowing device in the above embodiment. The blowing device in this embodiment is a clothes drying machine. As an alternative embodiment, the blowing device can also be a bathroom heater, a heater, an air conditioner, a dehumidifier, or a humidifier.
