Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "disposed," "connected," and "installed" should be understood in a broad sense, for example, to refer to fixed connections, detachable connections, or integral connections. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0041] Based on the problem pointed out in the background technology that the fresh air outlet of the existing air conditioner is not blocked and causes dust to fall, the utility model provides an air conditioner, which aims to set a driving mechanism and a baffle. When the air conditioner does not blow fresh air into the room, the driving mechanism can drive the baffle to move, so that the baffle blocks the fresh air outlet, thereby preventing indoor dust from entering the air conditioner through the fresh air outlet and causing pollution to the air conditioner, thereby improving the user experience.

[0042] Specifically, if Figures 1 to 4 As shown, the air conditioner of the present invention includes a shell 1 and a fan 2, a baffle 3 and a driving mechanism installed on the shell 1. A fresh air outlet 11 is provided on the shell 1. The air inlet 21 of the fan 2 is connected to the outside of the room. The air outlet 22 of the fan 2 can blow air toward the fresh air outlet 11. The driving mechanism can drive the baffle 3 to move so that the baffle 3 blocks / opens the fresh air outlet 11.

[0043] For example, Figures 1 to 4 As shown, the air conditioner of the present invention is arranged in the horizontal direction ( Figure 1 As shown in FIG), the air outlet of the air conditioner is arranged at the bottom of the housing 1, and the return air outlet and the fresh air outlet 11 of the air conditioner are arranged at the top of the housing 1, as shown in FIG. Figure 2 As shown, the fan 2 is installed in the shell 1, and the air inlet 21 of the fan 2 is connected to the outdoor environment through the air duct. The air outlet 22 of the fan 2 is set towards the fresh air outlet 11. When the fan 2 is turned on, the air conditioner can blow fresh air into the room. The baffle 3 and the driving mechanism are installed in the shell 1. The driving mechanism can drive the baffle 3 to move so that the baffle 3 blocks the fresh air outlet 11. By setting the driving mechanism and the baffle 3, when the air conditioner does not blow fresh air into the room, the driving mechanism can drive the baffle 3 to move so that the baffle 3 blocks the fresh air outlet 11, thereby preventing indoor dust from entering the air conditioner through the fresh air outlet 11 and causing pollution to the electrical components of the air conditioner, thereby improving the user experience.

[0044] It should be noted that the present invention does not limit the setting position of the baffle 3. For example, a person skilled in the art can set the baffle 3 on the outside of the shell 1, or on the outside inside the shell 1, or on the same plane as the outer surface of the shell 1, etc. As long as the fresh air outlet 11 can be blocked, such adjustment and change of the specific setting position of the baffle 3 does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0045] It should also be noted that the present invention does not limit the form of the driving mechanism. For example, those skilled in the art can set the driving mechanism to a motor + gear + rack structure, and drive the gear to rotate by the motor to drive the rack to drive the baffle to move. Or the driving mechanism can be set to an electromagnetic component, the baffle can be set to a magnet, and an elastic component can be set between the driving mechanism and the baffle, and the baffle can be driven to move by changing the current of the electromagnetic component, etc. Such adjustments and changes to the specific form of the driving mechanism do not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention.

[0046] Preferably, if Figures 1 to 4 As shown, an accommodating groove 12 is provided on the outer surface of the shell 1 of the present invention, the fresh air outlet 11 is provided in the accommodating groove 12 , and the baffle 3 is located in the accommodating groove 12 .

[0050] It should be noted that the present invention does not limit the form of the first guide structure and the second guide structure. For example, those skilled in the art can respectively set the first guide structure and the second guide structure as a matching guide plate and a guide block, and extend the guide plate into the gap between the guide block and the baffle 3 to move the baffle 3 along the guide plate. Alternatively, the first guide structure and the second guide structure can respectively be set as a matching guide groove and a guide block, and insert the guide block into the guide groove to move the baffle 3 along the guide groove, and so on. Such adjustments and changes to the specific structural forms of the first guide structure and the second guide structure do not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

[0051] Preferably, if Figure 1 and Figure 4 As shown, the first guide structure of the present invention is a guide plate, which extends along a first direction, which is the direction of movement of the baffle. The second guide structure is a guide block, which is L-shaped and has a gap with the inner surface of the baffle 3. At least a portion of the guide plate extends into the gap, and the guide block can move along the length direction of the guide plate.

[0052] Next, Figure 3 and Figure 4 For example, Figure 3 and Figure 4 As shown, the baffle 3 of the present invention can move in the up and down directions, the fresh air inlet 11 is arranged at the lower part of the accommodating groove 12, the guide plate is installed in the accommodating groove 12 along the up and down directions, and the top and bottom ends of the guide plate are fixedly connected to the inner surface of the shell 1, and an L-shaped guide block is provided on the inner surface of the baffle 3, and a part of the guide plate extends into the gap between the guide block and the inner surface of the baffle 3, so that the guide block can move up and down along the guide plate.

[0053] It should be noted that the present invention does not limit the number of the first guide structure and the second guide structure. For example, those skilled in the art can set the first guide structure and the second guide structure as one group or two groups, etc. Such adjustment and change of the specific number of the first guide structure and the second guide structure does not deviate from the principle and scope of the present invention, and should be limited within the protection scope of the present invention.

The first guide block 31 and the second guide block 32 are arranged between the first guide plate 13 and the second guide plate 14.

[0056] That is to say, a portion of the right side of the first guide plate 13 extends into the gap formed by the first guide block 31 and the baffle 3, and a portion of the left side of the second guide plate 14 extends into the gap formed by the second guide block 32 and the baffle 3, thereby being able to stably confine the baffle 3 in the gap and also enabling the baffle 3 to move more smoothly.

[0057] It should be noted that a gap needs to be reserved between the first guide plate 13 and the second guide plate 14 and the side wall of the accommodating groove 12 to allow the first guide block 31 and the second guide block 32 to pass through, so that the baffle 3 can move in the accommodating groove 12 without hindrance.

[0058] It should also be noted that the present invention does not limit the number of the first guide blocks 31 and the second guide blocks 32. For example, a person skilled in the art may set the first guide blocks 31 to 2 or 3 in the up and down directions, or may set the second guide blocks 32 to 2 or 3 in the up and down directions, and so on. Such adjustment and change of the specific number of the first guide blocks 31 and the second guide blocks 32 does not deviate from the principle and scope of the present invention, and should be limited within the scope of protection of the present invention.
