The first through hole 216 is opened in the middle of the sinking groove 215 so that the lower end of the column 207 can be inserted. The slide groove 217 is constructed on one side of the top surface of the sinking groove 215, and the protrusion 214 is inserted into the slide groove 217. The first baffle 220 is constructed on a side wall of the sinking groove 215, and has a second gap between it and the top surface of the sinking groove 215, so that one side of the convex ring 211 can be inserted, which is used to limit the convex ring 211.

[0083] As a possible implementation, the swing blade device 200 also includes a temperature sensor 218, which is installed on a fixing plate 228, generally by means of screws. The temperature sensor 218 is communicatively connected to the control device 104, generally by means of a connecting line, so as to obtain the air outlet temperature value of the air conditioner 100, which is used to determine whether the air outlet temperature of the air conditioner 100 is abnormal based on the air outlet temperature value.

[0084] Specifically, for example, when the air conditioner 100 is turned on and in cooling mode, the air conditioner 100 will draw in the air in the room, cool it through the condenser, and then send it back to the room. At this time, the air supply temperature of the air conditioner 100 is usually lower than the set 25°C, generally between 14° and 16°C. When the temperature obtained by the first temperature sensor 218 is 12°C and remains at 12°C, it is determined that the air outlet temperature of the air conditioner 100 is abnormal, and the control device 104 sends a prompt message to the remote control so that the user can check the cause of the abnormal air outlet temperature of the air conditioner 100 according to the prompt, so that the customer can repair or clean the filter to improve the user experience.

[0085] As a possible implementation, the swing blade device 200 also includes a camera 219, which is installed on the shell 103, generally embedded and fixed by screws, and is used to obtain whether there is a user near the air conditioner 100. The camera 219 and the control device 104 are communicated and connected, generally through a connecting line, so as to adjust the air outlet direction according to the position of the person.

[0086] Specifically, the camera 219 obtains information about whether there is a user near the air conditioner 100. When a user is near the air conditioner 100, the user's position is determined, and the control device 104 controls the motor 225 to operate according to the user's position. The motor 225 drives the connecting rod 226 to drive the multiple swing blades 201 to rotate to a position opposite to the user's position to avoid direct blowing on the user.

[0087] In a second aspect, the present invention provides an air conditioner, the air conditioner 100 comprising the swing blade device for air conditioner of the first aspect. The air conditioner 100 of this technical solution comprises the swing blade device 200 for air conditioner as any technical solution of the present invention, and thus has all the technical effects of the swing blade device for air conditioner of any technical solution of the present invention.
