When the air conditioner works in a normal mode, the first pull rod and the second pull rod are pulled in opposite directions simultaneously to drive the wind sweeping blades to rotate along the Z-axis direction, and wind sweeping movement is implemented.
As shown in fig. 1-5, the present invention provides a two-degree-of-freedom wind sweeping blade structure for cleaning an air duct of an air conditioner, comprising: the wind sweeping blade fixing device comprises a first pull rod 1, a second spherical hinge 2, a wind sweeping blade 3, a first spherical hinge 4, a wind sweeping blade fixing plate 5, a second pull rod 6 and a limit stop 7.
According to the invention, the wind sweeping blade fixing plate 5 and the wind sweeping blade 3 are connected by adopting a spherical hinge, one degree of freedom is limited by the limit stop 7, and the first pull rod 1, the second pull rod 6 and the wind sweeping blade 3 are connected by adopting the spherical hinge.

Examples
As shown in fig. 1-5. The invention is developed around the cleaning of the air duct of the air conditioner indoor unit, the air duct of the air conditioner indoor unit is one of the main places needing cleaning, in the traditional air conditioner indoor unit design, when the cold air passing through the evaporator is blown out by the cross-flow fan blade, the air duct is bent, so that dust is easily accumulated in the friction process with the air, and once the dust is accumulated, bacteria are propagated, the air quality in a room is certainly greatly influenced. The invention mainly solves the problem of insufficient space when an air conditioner indoor unit is cleaned, and the most main factor influencing the cleaning air channel is the blockage of the transverse wind sweeping blade when the air conditioner indoor unit is cleaned, and improves the structure of the transverse wind sweeping blade, so that the invention can ensure the forward wind sweeping motion (namely the rotation around the Z axis direction, as shown in figure 5), and can also realize the folding motion of the blade in the direction close to the shell (namely the motion around the X axis direction)
As shown in fig. 3-4, the blade of the present invention is a structure with two degrees of freedom motion, and the design takes into account the problems of operating space and cost, the structural design of the wind-sweeping blade should not be too complex, and at the same time, because the wind-sweeping blade is usually designed as an injection molding, the structural design should be simplified, and in the general two-degree-of-freedom structure, the structure is more complex, so the present invention adopts a ball pair improved structure, the ball pair is a three-degree-of-freedom structure, if the ball pair is directly used, the rotational freedom degree in the Y-axis direction will inevitably affect the wind direction control of the wind-sweeping blade, and the control is more complex, therefore, the two sides of the rod of the ball pair are required to be added with limit stops 7 along the Y-axis direction during the structural design, so as to ensure that the wind-sweeping blade will not generate redundant motion during the motion. After the structural design is completed, the original wind sweeping blade is designed to move with single degree of freedom, the motion of the wind sweeping blade is controlled simply, only one pull rod is needed, the blade has more degrees of freedom, the wind sweeping blade is designed to be controlled in a double-pull-rod differential mode, the wind sweeping blade is specifically designed to be connected with an independent pull rod on each of the inner side and the outer side of the wind sweeping blade, when the wind sweeping blade is in a normal working mode, the first pull rod 1 and the second pull rod 6 are pulled towards opposite directions simultaneously to drive the wind sweeping blade to rotate along the Z-axis direction, the wind sweeping motion can be realized, when an air conditioner enters a cleaning mode, the pull rods can adjust the wind sweeping blade 3 to the direction vertical to the Y-axis, then the two pull rods synchronously move, the wind sweeping blade can be folded, and a space is provided for cleaning an air duct of an indoor unit of.
