[0032] The present utility model provides a fresh air device.

[0033] Please refer to Figure 1 、 Figure 3 and Figure 5 In an embodiment of the present utility model, the fresh air device includes:

[0034] A housing 100 having a first air outlet area 110 and a second air outlet area 120. At least one first air outlet 111 is provided in the first air outlet area 110, and at least one second air outlet 121 is provided in the second air outlet area 120; and

[0035] A door body 200 movably connected to the housing 100 and capable of selectively covering between the first air outlet area 110 and the second air outlet area 120.

[0036] It can be understood that as Figure 2 shown, an air duct member 410 is provided in the housing 100 of the fresh air device. An air duct 411 is formed in the air duct member 410. An air wheel 420 is installed in the air duct 411. The outlet of the air duct 411 is arranged opposite to the first air outlet area 110 and the second air outlet area 120. Driven by the air wheel 420, the air flow is guided through the air duct 411 to blow air to the first air outlet area 110 or the second air outlet area 120.

[0037] In the technical solution of the present utility model, the door body 200 selectively covers the first air outlet area 110 and the second air outlet area 120, that is, it can selectively open the first air outlet area 110 and the second air outlet area 120. Since the distribution positions of the first air outlet area 110 and the second air outlet area 120 on the housing 100 are different, the fresh air device can blow air in different positions through the first air outlet 111 of the first air outlet area 110 and the second air outlet 121 of the second air outlet area 120, bringing different blowing sensations to the user. Moreover, the air outlet areas of the first air outlet area 110 and the second air outlet area 120, as well as the shapes and sizes of the first air outlet 111 and the second air outlet 121, can be designed differently to improve the air outlet difference between the first air outlet area 110 and the second air outlet area 120, so that the first air outlet area 110 and the second air outlet area 120 can meet the air supply requirements of the user for the fresh air device at more levels.

[0038] For example, the air outlet areas of the first air outlet area 110 and the second air outlet area 120 can be designed differently. It can be that the air outlet area of the first air outlet area 110 is smaller than that of the second air outlet area 120. The fresh air device has a smaller air volume when blowing air through the first air outlet area 110 and a larger air volume when blowing air through the second air outlet area 120. In this way, the user can selectively open the first air outlet area 110 or the second air outlet area 120 according to the required air volume. When the air outlet areas of the first air outlet area 110 and the second air outlet area 120 are large enough, the smaller air outlet area of the first air outlet area 110 is conducive to concentrated air outlet, and the larger air outlet area of the second air outlet area 120 is conducive to dispersed air outlet. The user can choose to open different air outlet areas according to whether fresh air needs to blow directly.

[0039] Again, the extension directions of the first air outlet 111 and the second air outlet 121 can be designed differently. Specifically, the first air outlet 111 and the second air outlet 121 can be strip-shaped or quasi-strip-shaped (such as runway-shaped, peanut-shaped, oval-shaped, etc.). Their length directions are also their extension directions. Different extension directions of the first air outlet 111 and the second air outlet 121 can make the horizontal and vertical components of the first air outlet 111 and the second air outlet 121 different. Or, when the components in the above two directions are the same, the overall lengths of the first air outlet 111 and the second air outlet 121 can be different, making the air outlet area have slight differences, which can adapt to the user's personalized adjustment of the air outlet area in the horizontal direction and the vertical direction, or meet the user's fine adjustment of the air volume of the fresh air device.

[0040] Further, in this embodiment, the first air outlet 111 extends in the horizontal direction, and the second air outlet 121 extends in the vertical direction. Thus, if the first air outlet 111 has a sufficient extension in the horizontal direction and the second air outlet 121 has a sufficient extension in the vertical direction, when the door body 200 opens the first air outlet 111, the fresh air device can have a sufficient air outlet area in the horizontal direction, which is beneficial to the diffusion of fresh air in the horizontal direction. When the door body 200 opens the second air outlet 121, the fresh air device can have a sufficient air outlet area in the vertical direction, which is beneficial to the diffusion of fresh air in the vertical direction. That is to say, in this embodiment, the extending directions of the first air outlet 111 and the second air outlet 121 are beneficial to making the air supply ranges of the fresh air device in the horizontal direction and the vertical direction different, so that the user can flexibly choose to open the first air outlet 111 or the second air outlet 121 according to their own needs. Of course, in other embodiments, the first air outlet 111 and the second air outlet 121 may also extend obliquely.

[0041] Further, in this embodiment, a plurality of the first air outlets 111 are arranged in the vertical direction in the first air outlet area 110, and a plurality of the second air outlets 121 are arranged in the horizontal direction in the second air outlet area 120, and the distribution densities of the plurality of the first air outlets 111 and the plurality of the second air outlets 121 are different. It can be understood that when there are a plurality of air outlets in the air outlet area, the range of the air outlet area is determined by the air outlets on the side. Specifically, the horizontal range of the first air outlet area 110 is determined by the length of each first air outlet 111 in the horizontal direction, and the vertical range of the first air outlet area 110 is determined by the edges on the opposite sides of the two side first air outlets 111. The same reference applies to the second air outlet area 120.

[0042] Further, in this embodiment, the distance between any two adjacent first air outlets 111 is greater than the distance between any two adjacent second air outlets 121. That is to say, the distribution density of the plurality of first air outlets 111 is smaller, and the plurality of first air outlets 111 are more dispersedly distributed in the first air outlet area 110. The distribution density of the plurality of second air outlets 121 is larger, and the plurality of second air outlets 121 are more concentratedly distributed in the second air outlet area 120. Thus, the air outlet of the first air outlet area 110 is more dispersed, and the air outlet of the second air outlet area 120 is more concentrated. The user can choose to open different air outlet areas according to whether fresh air is needed to blow directly.

[0043] Further, in this embodiment, the first air outlet area 110 and the second air outlet area 120 are distributed in the horizontal direction. The first air outlet area 110 is provided with two first air outlets 111, and the two first air outlets 111 are respectively arranged corresponding to the two ends of the second air outlet 121. That is, the two first air outlets 111 are relatively dispersed in the vertical direction and extend in the horizontal direction. In this way, when the air blows out from the first air outlet area 110, the air flow can be relatively dispersed in both the horizontal and vertical directions, so as to reduce the direct blowing feeling of the fresh air device when it blows out, thereby improving the comfort of the user. In addition, since the first air outlet 111 is arranged corresponding to the end side of the second air outlet 121, the sizes of the first air outlet area 110 and the second air outlet area 120 in the vertical direction can be relatively close. When the door body 200 covers the first air outlet area 110 and the second air outlet area 120, the sizes in the vertical direction are relatively well-matched and will not interfere with other structures. Of course, in other embodiments, the first air outlet area 110 and the second air outlet area 120 can also be distributed in the vertical direction.

[0044] Further, in this embodiment, one second air outlet area 120 is distributed on each of the opposite sides of the first air outlet area 110, and two corresponding door bodies 200 are provided. The two door bodies 200 can move between positions where they respectively cover the two second air outlet areas 120 and a position where they jointly cover the first air outlet area 110. It can be understood that the distance between the two first air outlets 111 is not too long, and the extension amount of the second air outlet 121 in the vertical direction is also relatively limited. In this embodiment, by providing one second air outlet area 120 on each side of the first air outlet area 110, when the first air outlet area 110 is covered by the door body 200, the fresh air device blows out air from the two second air outlet areas 120 together, which is beneficial to ensuring the air volume of the fresh air device, so as to realize a large air volume of oncoming wind and provide more fresh air volume for the user. Moreover, the two second air outlet areas 120 are separated by the first air outlet area 110. While ensuring concentrated air outlet, there is also a certain amount of dispersion, avoiding excessive concentration of the air flow, resulting in excessive air outlet noise or too strong a wind feeling for the user.

[0045] Further, in this embodiment, the two door bodies 200 can respectively fit to cover the second air outlet area 120 and can jointly fit to cover the first air outlet area 110. That is, the length of the two second air outlet areas 120 overlapping in the horizontal direction is close to the length of the first air outlet area 110 in the horizontal direction. In this way,

[0046] Further, in this embodiment, the door body 200 is slidably connected to the housing 100. It can be understood that the sliding direction of the door body 200 is parallel to the distribution direction of the first air outlet area 110 and the second air outlet area 120. In this way, when the door body 200 slides between the first air outlet area 110 and the second air outlet area 120, it can selectively cover the first air outlet area 110 or the second air outlet area 120. Of course, in other embodiments, the door body 200 can also be rotatably connected to the housing 100. A rotating shaft is correspondingly arranged at one side edge of the door body 200, and the position of the rotating shaft is at the boundary between the first air outlet area 110 and the second air outlet area 120. By rotating the door body 200, the door body 200 can be flipped to cover the first air outlet area 110 or the second air outlet area 120.

[0047] Further, in this embodiment, as Figure 4 and Figure 6 shown, the fresh air device is further provided with a driving device 310. The driving device 310 is connected with a driving gear 320, the door body 200 is connected with a transmission rack 330, and the driving gear 320 is meshed and connected to the transmission rack 330. In this way, after the driving device 310 operates, it can drive the driving gear 320 to rotate. Thus, through the meshing cooperation of the driving gear 320 and the transmission rack 330, the rotation of the driving gear 320 can be converted into the linear movement of the transmission rack 330 to drive the door body 200 to slide. Specifically, the driving gear 320 can be coaxially and fixedly connected to the output shaft of the driving device 310, or can be in transmission cooperation with the gear fixedly connected to the output shaft of the driving device 310 to achieve the effect of speed reduction or layout optimization; the driving device 310 can be installed on the housing 100 or on the top side of the air duct member 410. Of course, in other embodiments, the driving device 310 can also drive the door body 200 to slide in other ways, such as a lead screw slider device.

[0048] Furthermore, corresponding to the two door bodies 200, two driving devices 310 can be provided. The two driving devices 310 respectively drive the two transmission racks 330 through the two driving gears 320 to respectively drive the two door bodies 200. Of course, it can also be that only one driving device 310 is provided, and the opposite sides of the driving gear 320 connected to the driving device 310 are respectively meshed and connected to two rack structures, and these two rack structures are respectively connected to the two door bodies 200. In this way, driving the two door bodies 200 to move through one driving device 310 can improve the synchronization of the movement of the two door bodies 200.

[0049] The present utility model further provides an air conditioner, which includes a fresh air device. The specific structure of the fresh air device refers to the above-mentioned embodiments.
