[0030] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figures 1 to 7 As shown, an embodiment of the present invention provides a wind shield mechanism, comprising: a wind shield portion 10, which is used to be arranged at the air inlet of the air conditioner, the wind shield portion 10 comprises a baffle 11 and a first lug 12 arranged on the baffle 11, there are multiple wind shield portions 10, and the multiple wind shield portions 10 are arranged side by side; a driving portion 20, the driving portion 20 comprises a plurality of rotating shafts 21 arranged side by side, the multiple rotating shafts 21 correspond to the multiple first lugs 12 one by one, and each first lug 12 is detachably engaged with the corresponding rotating shaft 21, and the rotating shaft 21 is used to drive the corresponding wind shield portion 10 to rotate; wherein the wind shield portion 10 has a closed position and an open position, when the wind shield portion 10 is in the closed position, any two adjacent baffles 11 abut or overlap each other to close the air inlet, and when the wind shield portion 10 is in the open position, any two adjacent baffles 11 are spaced apart to open the air inlet.

[0032] With this solution, multiple rotating shafts 21 and multiple first lugs 12 are arranged one by one, and each first lug 12 is detachably connected to the corresponding rotating shaft 21. With this arrangement, when the air conditioner is not used for a long time and the baffle 11 is full of dust, it is convenient for the user to disassemble it. After cleaning, it is only necessary to connect the first lug 12 to the corresponding rotating shaft 21 to complete the installation. Compared with the prior art, there is no need to disassemble the entire windshield 10 together with the motor 24, which reduces the difficulty of disassembling and installing the windshield 10. Therefore, this solution effectively solves the problem that the windshield mechanism is not easy to disassemble. Among them, when the windshield 10 is in the closed position, any two adjacent baffles 11 are abutted or overlapped with each other, and the air inlet is closed, which effectively reduces or avoids the accumulation of dust at the air inlet; when the windshield 10 is in the open position, any two adjacent baffles 11 are spaced apart, and the air inlet is opened, thereby realizing the function of air intake.

[0033] In the present solution, when the air conditioner is not used for a long time and dust accumulates on the baffle 11, the user can disassemble and clean the baffle 11 by himself, and the simple disassembly method can prevent the user from damaging the parts structure by disassembling it by himself without knowing the wind shield mechanism. At the same time, the structure of the baffle 11 is simple, which is more convenient for after-sales maintenance. A single baffle 11 can be replaced separately after being damaged, and there is no need to replace the entire wind shield mechanism, thereby reducing maintenance costs.

[0034] The rotating shaft 21 includes a rod body 211 and a positioning rib 212 arranged on the outer circumference of the rod body 211. The first lug 12 has a clamping groove 121 and a positioning groove arranged on the inner wall of the clamping groove 121. The rod body 211 is clamped in the clamping groove 121, and the positioning rib 212 is located in the positioning groove. By providing the positioning rib 212 on the outer circumference of the rod body 211, the rotating shaft 21 can be positioned; the clamping groove 121 is provided to facilitate the rod body 211 to be clamped into the clamping groove 121; and the positioning groove is provided to cooperate with the positioning rib 212. The inclination angles of the multiple positioning ribs 212 are kept consistent, so that it is convenient for users to disassemble the rod body 211.

By setting the thickness of the positioning rib 212 to gradually decrease from the bottom end to the top end, it has a guiding effect when assembling the positioning groove and the positioning rib 212, which is more convenient for users to assemble after cleaning.

[0036] In this embodiment, the side of the baffle 11 away from the first lug 12 has a windshield surface 111, the end where the positioning rib 212 and the rod body 211 are connected is the bottom end, the end of the positioning rib 212 away from the rod body 211 is the top end, and the direction from the bottom end to the top end is parallel to the windshield surface 111. The windshield surface 111 is provided to effectively prevent dust from entering the air inlet of the air conditioner; the positioning rib 212 is provided in parallel to the windshield surface 111 from the bottom end to the top end, and when the windshield 10 is in the closed position, the positioning rib 212 will not hinder the windshield 10. In addition, when the windshield 10 is in the open position, the user only needs to pull along the direction of the windshield surface 111 to remove the baffle 11, which is convenient for force application and operation.

[0037] In this embodiment, the rod body 211 is a cylindrical rod, the diameter of the rod body 211 is d, and the opening of the slot 121 is a, wherein 0.6d≤a≤0.85d. By limiting the diameter d of the rod body 211 and the size of the opening a of the slot 121 to the above numerical range, it can be ensured that the rod body 211 is smoothly inserted into the slot 121, and the connection is secure after insertion.
