Referring to fig. 2, 3 and 4 in combination, the air conditioner wind guiding device 200 includes a housing box 210, a driving motor 220 installed in the housing box 210, a wind gate 230, a first gear 240, a second gear 250, a first link 260, a second link 270, a sliding limiting member 280 and a stop member 290. The air guide door 230 is used for opening or closing the air outlet 310, in this embodiment, the air guide door 230 has three cut-off states, and one cut-off state is that the air guide door 230 closes the air outlet 310, and the air conditioner 10 is not operated at this time; the other cut-off state is that the air guide door 230 rotates to the vicinity of an angle perpendicular to the ground, at this time, the air conditioner 10 heats, the air guide door 230 guides hot air to blow to the ground, so as to sink the warm air as much as possible and warm the legs and feet of a user, thereby improving the comfort of the air conditioner 10 and enhancing the experience of the user; the other cut-off state is that the air guide door 230 is rotated to the vicinity of an angle parallel to the ground, and at this time, the air conditioner 10 cools, and the air guide door 230 guides the cool air to blow into the air, so that the cool air gradually sinks, and the indoor temperature is uniformly reduced.
The driving motor 220 is mounted on the accommodating box 210 and connected to the first gear 240 to drive the first gear 240 to rotate. The first link 260 is provided with a first rack portion 261 for meshing with the first gear 240, the second link 270 is provided with a second rack portion 271 for meshing with the second gear 250, the first rack portion 261 and the second rack portion 271 are arc-shaped, the first gear 240 rotates while driving the first rack portion 261 to rotate along the arc, thereby driving the first link 260 to rotate, and the second gear 250 rotates while driving the second rack portion 271 to rotate along the arc, thereby driving the second link 270 to rotate.
The first gear 240 is disposed coaxially with the second gear 250, and the diameter of the first gear 240 is larger than the diameter of the second gear 250, so that the rotation speed of the first rack portion 261 is smaller than the rotation speed of the second rack portion 271, i.e., the rotation speed of the first link 260 is smaller than the rotation speed of the second link 270, with the same rotation speeds of the first gear 240 and the second gear 250. One end of the first link 260 has a first rotation center 262, one end of the second link 270 has a second rotation center 272, the first rotation center 262 and the second rotation center 272 are located on the same axis, and the first link 260 and the second link 270 can both rotate around the axis.
The first gear 240 is coupled to the second gear 250 by a slip limiting member 280, and the slip limiting member 280 is used to selectively synchronize rotation of the first gear 240 with the second gear 250. The sliding limiting piece 280 has a sliding limiting force, and when the external force acting on the second gear 250 is smaller than the sliding limiting force, the first gear 240 drives the second gear 250 to synchronously rotate; when the external force acting on the second gear 250 is equal to or greater than the slip limiting force, the first gear 240 continues to rotate under the driving motor 220, and the second gear 250 is stationary. In the present embodiment, an external force capable of making the second gear 250 stationary is applied to the second link 270 through the stopper 290.
The stopper 290 is mounted on the receiving box 210 and spaced apart from the second link 270. The stopper 290 is used to selectively abut the second link 270 to apply an external force to the second link 270. When the stop member 290 does not support the second link 270, the limited slip force is greater than the friction force of the rotation of the second gear 250, and the first gear 240 drives the second gear 250 to rotate through the limited slip member 280; when the stopper 290 abuts the second link 270, the generated abutting force is greater than or equal to the limited slip force, the second gear 250 is forced to be stationary, and the first gear 240 rotates relative to the second gear 250.
The slip limiting member 280 is installed between the first gear 240 and the second gear 250, and the slip limiting member 280 is connected with the first gear 240 and the second gear 250, respectively, to generate a slip limiting force capable of synchronously rotating the first gear 240 and the second gear 250.

The first side 281 is fixedly connected to the first gear 240, and the second side 283 abuts against an end surface of the second gear 250. When the stop member 290 does not abut against the second link 270, the sliding limiting member 280 drives the second gear 250 to rotate by the friction force between the second side 283 and the second gear 250; when the stopper 290 abuts against the second link 270, the stopper 290 generates an abutting force against the second link 270 to overcome the friction force between the second side 283 and the second gear 250, so that the second side 283 and the second gear 250 rotate relatively, and the first gear 240 continues to rotate, and the second gear 250 is stationary.
In other embodiments, the first side 281 abuts against an end surface of the first gear 240, and the second side 283 is fixedly connected with the second gear 250. When the stop member 290 does not abut against the second link 270, the first gear 240 drives the sliding limiting member 280 to rotate by the friction force between the first gear 240 and the first side 281; when the stop member 290 abuts against the second link 270, the stop member 290 generates an abutting force against the second link 270 to overcome the friction force between the first gear 240 and the first side 281, so that the first gear 240 and the first side 281 rotate relatively, and at this time, the first gear 240 continues to rotate, and the second gear 250 is stationary.
The damper 230 includes a wind guide 231, a first hinge 233, and a second hinge 235. The first hinge 233 and the second hinge 235 are connected to the air guide 231.

The second link 270 can only move between two extreme positions, namely between the first and second stops 291, 293.
In this embodiment, the first stopper 291 is further used for abutting against one side of the first link 260, and the second stopper 293 is further used for abutting against the other side of the first link 260. The first and second stoppers 291 and 293 define a range of movement of the first link 260, and the first link 260 is only movable between the first and second stoppers 291 and 293. However, in other embodiments, the rotation range of the first gear 240 can be directly controlled by the driving motor 220, and the first gear 240 drives the first link 260 to rotate, i.e. the movement range of the first link 260 is controlled.
