Figure 2 and Figure 3 As shown, the drive assembly 2 is installed at the bottom of the air inlet bracket 1. The drive assembly 2 includes a motor 21, a driving gear 22 and a transmission gear 23. The motor 21 is installed at the bottom of the air inlet bracket 1. The driving gear 22 is set on the rotating shaft of the motor 21. The driving gear 22 is sleeved on the rotating shaft of the motor 21. The driving gear 22 is driven to rotate by the rotating shaft of the motor 21. The transmission gear 23 is set at one end of the swing blade 3. The transmission gear 23 is engaged with the driving gear 22 to drive the swing blade 3 to rotate. The driving gear 22 drives the transmission gear 23 engaged with it to rotate, thereby driving the swing blade 3 to rotate. Figure 1 and Figure 6 As shown, the swing blade 3 is horizontally arranged in the opening of the air inlet bracket 1. The two ends of the swing blade 3 are provided with a rotating shaft, and the swing blade 3 is connected to the side wall of the air inlet bracket 1 through the rotating shaft. The air inlet bracket 1 is square in shape, and its area is the same as the air inlet size of the air conditioner. The opening of the air inlet bracket 1 is also square in shape, as shown in FIG. Figure 7 As shown, when the air conditioner is turned on, the swing blade 3 rotates forward and the air inlet of the air conditioner is opened to ensure the ventilation effect of the air conditioner. Figure 6 As shown, when the air conditioner is turned off, the swing blade 3 is reversed and the air inlet of the air conditioner is closed to prevent dust from falling into the filter and causing the filter to become dirty and clogged.
[0032] Specifically, if Figure 1 As shown, there are a plurality of swing blades 3, and all the swing blades 3 are arranged parallel to each other. When the air conditioner is turned on or off, under the action of the motor 21, all the swing blades 3 move synchronously.
[0033] Specifically, if Figure 1 and Figure 4 As shown, each of the two bottom ends of each oscillating blade 3 is provided with a first connecting piece 32. The two first connecting pieces 32 of each oscillating blade 3 are symmetrically arranged. At least three second connecting pieces 33 are provided between the two first connecting pieces 32. The first connecting piece 32 and the second connecting piece 33 are perpendicular to the main body of the oscillating blade 3. A rotatable shaft is provided on each of the first connecting piece 32 and the second connecting piece 33.
[0034] Specifically, the end shaft 31 is perpendicularly mounted on the first sheet-like connector 32, and the end of the second sheet-like connector 33 is provided with a hinge shaft 34 perpendicular to the main body of the second sheet-like connector 33. The end shaft 31 and the hinge shaft 33 are arranged on the same axis. The swing blade 3 swings along this axis.
[0035] Specifically, if Figure 4 and Figure 5As shown, the pendulum blades 3 are divided into one or two groups. The pendulum blades 3 in the same group are connected by connecting rods 4 on both sides of the pendulum blades 3. The connecting rods 4 are provided on the first sheet-shaped connecting body 32 of the pendulum blades 3 in one group and are hinged to the first sheet-shaped connecting body 32 of the pendulum blades 3.

[0036] Specifically, if Figure 2 and Figure 3 As shown, a group of pendulum blades 3 is provided with at least one drive assembly 2. The transmission gear 23 of the drive assembly 2 is provided at one end of the corresponding pendulum blade 3, and the transmission gear 23 is sleeved on the end shaft 31 of the corresponding pendulum blade 3. The end shaft 31 provided with the drive assembly 2 passes through the frame of the air inlet bracket 1 and is connected to the transmission gear 23 of the drive assembly 2. A fixed column is provided within the end shaft 31, and a rotatable housing is mounted on the fixed column. The housing is provided on the air inlet bracket 1. The fixed column passes through the air inlet bracket 1 and is connected to the transmission gear 23, which is sleeved on the fixed column. The transmission gear 23 is engaged or fixedly connected to the fixed column. The pendulum blade 3 provided with the transmission gear 23 is driven by the driving gear 22 of the motor 21 to rotate. The driving gear 22 drives the meshed transmission gear 23 to rotate, thereby driving the pendulum blade 3 connected to the transmission gear 23 to rotate. The remaining pendulum blades 3 are driven to rotate via the connecting rod 4.
[0037] Specifically, if Figure 1 As shown, a plurality of sheet-like support bodies 11 are longitudinally arranged at the bottom of the opening of the air inlet bracket 1, and a plurality of protrusions 14 are arranged on the sheet-like support body 11 along the length direction. The protrusions 14 correspond one-to-one with the second sheet-like connectors 33, which is equivalent to the number of all protrusions 14 being the same as the number of all second sheet-like connectors 33, and the positions of the protrusions 14 correspond to the positions of the second sheet-like connectors 33.
[0038] Specifically, if Figure 1 As shown, a portion of the protrusions 14 are provided with through holes 15 that are hingedly connected to the hinge shafts 34 on the corresponding second sheet-like connecting body 33, while the remaining protrusions 14 are provided with notches 16 that are hingedly connected to the hinge shafts 34 on the corresponding second sheet-like connecting body 33. By setting the hinge shafts 34 in the through holes 15 or the notches 16, the second sheet-like connecting body 33 can rotate relative to the sheet-like supporting body 11.
[0039] Specifically, a notch 16 is provided at the top of the protrusion 14, and the notch 16 is U-shaped, and the corresponding hinge shaft 34 is provided at the bottom of the U-shaped notch 16. The hinge shaft 34 is arranged in the through hole 15 to ensure the support function of the sheet support body 11 while preventing the hinge shaft 34 from falling off the protrusion 14. The hinge shaft 35 is arranged in the notch 16 to ensure the support function of the sheet support body 11 while facilitating the removal and replacement of the hinge shaft 34.
[0040] Specifically, one side of the protrusion 14 is provided with a groove 12 suitable for the swing blade 3 to swing. The swing blade 3, hinged at the end of the protrusion, swings along the side of the protrusion with the groove. The protrusion has an arc-shaped design on the side with the groove based on the swing path of the swing blade 3. When the air conditioner is turned on, the swing blade 3 rotates forward and swings into the groove 12.
[0041] Specifically, if Figure 2 As shown, the driving gear 22 is provided with an anti-slip plate 24 to prevent the transmission gear 23 from slipping out. The anti-slip plate 24 prevents the transmission gear 23 from slipping out of one side of the driving gear 22 during rotation. Furthermore, the mutual restraining effect between the anti-slip plate 24 and the first sheet-like connector 22 on the transmission gear 23 ensures the transmission gear 23 operates stably between the anti-slip plate 24 and the first sheet-like connector 22, preventing the transmission gear 23 from slipping out.

Sockets for the mounting feet 13 are provided on the inner sidewall of the air inlet. A motor 21 for the air inlet closing device is connected to the air conditioner controller. The mounting feet 13 of the air inlet closing device are inserted into the socket of the air inlet to prevent the air inlet closing device from falling out of the air conditioner inlet.
[0044] Specifically, a buckle is provided at the connection between the air inlet of the air conditioner and the air inlet closing device to prevent the air inlet closing device from falling off.
[0045] The specific working states of an air-conditioning air inlet closing device and an air-conditioning provided by the present invention are as follows:
[0046] When the air conditioner is turned on, the motor 21 works, and the motor 21 drives the driving gear 22 to rotate through the rotating shaft. The driving gear 22 drives the transmission gear 23 to rotate. The transmission gear 23 and the connecting rod 4 drive the swing blade 3 to rotate forward, and the air inlet is opened to ensure the ventilation effect of the air conditioner; when the air conditioner is turned off, the motor 21 works, drives the swing blade 3 to reverse, and the air inlet is closed to prevent dust from falling into the air inlet and clogging the filter when the air conditioner is turned off.
