机壳10为空心柱状结构，机壳10内部设置有新风通道，新风管20的一端与机壳10连接，新风管20与新风通道连通。在空调室内机处于新风模式时，室外空气通过新风管20进入新风通道内，以实现换新风。
需要说明的是，非新风模式可以为空调室内机处于停机模式、制冷模式、制热模式、除湿模式、自清洁模式等。
如图2所示，新风管20设置有连接件21和护圈22。护圈22位于墙壁安装孔的内侧，护圈22用于与墙壁安装孔配合，以覆盖新风管20与墙壁安装孔的孔壁之间的间隙，以避免室外的灰尘和杂质从新风管20与墙壁安装孔的孔壁之间的间隙进入室内。连接件21用于与机壳10连接。连接件21和护圈22为空调器领域常用的备用件。
如图2和图7所示，新风管帽30可以为中空的柱体。新风管帽30包括相互连接的第一段31和第二段32，第一段31和第二段32均沿新风管帽30的轴向延伸。新风管帽30的第一段31与新风管20连接，新风管帽30的第二段32上设置有进风孔301。进风孔301可以圆孔，也可以为长圆孔，在此不做具体设置。
新风管帽30的第一段31与新风管20之间可以通过螺纹连接。在其他实现方式中，新风管帽30的第一段31与新风管20之间也可以通过其他方式连接，在此不做具体设置。
新风管帽30的第二段32包括第一区域321和第二区域322，第一区域321和第二区域322以新风管帽30的轴线相对设置。
在一种可选的实施方式中，如图7所示，第一区域321包括第一侧壁 3211和第一端壁3212，第二区域322包括第二侧壁3221和第二端壁3222，第一侧壁3211和第二侧壁3221相对设置，第一侧壁3211和第二侧壁3221相互连接围成柱形侧壁，第一端壁3212位于第一侧壁3211远离新风管帽30的第一段31的一端，第二端壁3222位于第二侧壁3221远离新风管帽30的第一段31的一端，第一端壁3212和第二端壁3222相互连接围成圆形端壁，第一端壁3212、第二侧壁3221和第二端壁3222上均设置有进风孔301。
第一侧壁3211和第二侧壁3221的形状均为半圆柱形。第一端壁3212和第二端壁3222的形状均为半圆形。第一端壁3212、第二侧壁3221和第二端壁3222上的进风孔301的数量均为多个。第一端壁3212的进风孔301在第一端壁3212上间隔设置；第二端壁3222的进风孔301在第二端壁3222上间隔设置；第二侧壁3221的进风孔301在第二侧壁3221上间隔设置。
需要指出的是，第一侧壁3211第一侧壁3211上未设置进风孔301。在新风管帽30伸出室外时，第一侧壁3211朝上，如此设置，在空调室内机处于新风模式时，可以避免雨水倒灌进入新风管20内。
如图10所示，旋转组件40包括摆叶41，摆叶41可旋转地设置在新风管帽30的第一段31内，摆叶41在新风管帽30的第一段31内靠近新风管帽30的第二段32设置，摆叶41用于使新风管帽30的第一段31和新风管帽30的第二段32之间打开或关闭。
需要说明的是，摆叶41旋转的轴线沿着新风管帽30截面的径向方向延伸。
在空调室内机处于新风模式时，摆叶41使新风管帽30的第一段31和新风管帽的第二段32之间打开，室外空气通过新风管帽的第二段32进入新风管帽30的第一段31，然后再经新风管帽30的第一段31进入新风管20内，实现换新风；在空调室内机处于非新风模式时，摆叶41使新风管帽30的第一段31和新风管帽的第二段32之间关闭，使得室外空气无法进入室内，且室外的浮尘或碎屑被摆叶41阻挡，无法通过新风管帽30的第一段31进入新风管20内，从而可以避免室外的浮尘或碎屑进入到新风管20内。
摆叶41可以为圆柱平板。在摆叶41使新风管帽30的第一段31和新风管帽的第二段32之间关闭时，摆叶41与新风管帽30的第一段31的内壁相抵接。

需要说明的是，第一轴线沿着新风管帽30截面的径向方向延伸。
可选地，如图10所示，旋转组件40还包括电机42，电机42安装在新风管帽30的外壁上，电机42的电机轴与摆叶41连接。电机42可以为步进电机。
需要说明的是，电机42的电机轴与摆叶41可以直接连接，也可以通过传动件间接连接。
在一些示例中，电机42的电机轴与摆叶41直接连接。如图3和图4所示，电机42通过电机轴驱动摆叶41沿第一方向旋转时用于使新风管帽30的第一段31和新风管帽30的第二段32之间关闭；如图5和图6所示，电机42通过电机轴驱动摆叶41沿与第一方向相反的第二方向旋转时用于使新风管帽30的第一段31和新风管帽30的第二段32之间打开。
需要指出的是，第一方向可以为电机42的电机轴正转的方向，第二方向可以为电机42的电机轴反转的方向。在其他示例中，第一方向可以为电机42的电机轴反转的方向，第二方向可以为电机42的电机轴正转的方向。
图11为图10的摆叶的结构示意图；图12为图10的转轴的结构示意图。
进一步地，如图11和图12所示，旋转组件40还包括转轴43和传动件44，摆叶41设置有固定孔411，固定孔411沿着第一轴线延伸，转轴43固定在固定孔411中，且转轴43贯穿固定孔411，转轴43的第一端431插设在新风管帽30的第一段31内，转轴43的第二端432贯穿新风管帽30的第一段31，传动件44连接在转轴43与电机42的电机轴之间，传动 件44用于将电机42的驱动力传递给转轴43。通过转轴43的第一端431插设在新风管帽30的第一段31内，可以保证转轴43不偏离第一轴线，从而可以保证摆叶41旋转的稳定性；通过传动件44将电机42的驱动力传递给转轴43，可以实现转轴43带动摆叶沿第一方向旋转或沿第二方向旋转，从而可以实现新风管帽30的第一段31和新风管帽30的第二段32之间关闭或打开。
固定孔411的形状可以为圆柱型，也可以为方柱型，在此不做具体设置。固定孔411在摆叶41截面的径向上贯穿摆叶41。
转轴43的形状与固定孔411的形状相匹配。
传动件44可以为齿轮，也可以为联轴器，在此不做具体设置。在一些示例中，如图10所示，传动件44包括第一锥齿轮441和第二锥齿轮442，第一锥齿轮441与电机42的电机轴固定连接，第二锥齿轮442与转轴43的第二端432固定连接，第一锥齿轮441与第二锥齿轮442啮合，第一锥齿轮441的轴向与第二锥齿轮442的轴向垂直。通过设置第一锥齿轮441和第二锥齿轮442，可以使得电机轴与转轴43之间的传动平稳且噪音低。
第一锥齿轮441和第二锥齿轮442均位于新风管帽30的外侧。第一锥齿轮441的轴向方向平行于新风管帽30的轴向，第二锥齿轮442的轴向方向与第一轴线的延伸方向重合。
可选地，如图9所示，新风管帽30的第一段31设置有用于与转轴43的第一端431插设的转孔302，转孔302与转轴43的第一端431相互倒角配合。如此设置，可以使得转轴43在转孔302中顺滑旋转，避免转轴43在转孔302出现卡顿现象。
其中，转孔302沿着第一轴线的延伸方向延伸，转孔302未贯穿新风管帽30的第一段31。转孔302的形状可以为圆柱型。
新风管帽30的第一段31设置有用于使转轴43的第二端432贯穿的通孔304。通孔304的形状可以为圆柱型。

转轴43的第一端431的形状与转孔302的形状相匹配。
需要说明的是，防脱部3022为未倒角的孔。
可选地，如图10所示，旋转组件40还包括电机盒45，电机盒45安装在新风管帽30的外壁上，电机盒45包裹在电机42的外侧。如此设置，可以避免电机42在室外遭到自然天气破坏，从而可以提高电机42的使用寿命。
其中，电机42可以安装在新风管帽30的第二段32的第二侧壁3221上。电机盒45的形状在此不做具体设置，只要可以将电机42包裹起来就可以。
可选地，如图8和图9所示，新风管帽30的第二段32内设置有限制凸起303，限制凸起303位于新风管帽30的第二段32与新风管帽30的第一段31相交的一端，限制凸起303绕着第一轴线延伸，新风管帽30的第一段31与新风管帽30的第二段32处于打开或关闭状态时摆叶41与限制凸起303相抵接。如此设置，可以防止电机42过度旋转导致新风管帽30的第一段31与新风管帽30的第二段32之间未全部关闭或未全部打开。
需要说明的是，当电机42带动摆叶沿第一方向旋转时，如果电机42的电机过度旋转，会使得新风管帽30的第一段31与新风管帽30的第二段32之间不能全部关闭，从而导致在空调室内机处于非新风模式时，室外的浮尘或碎屑可能通过新风管帽30的第一段31进入新风管20内；当电机42带动摆叶沿第二方向旋转时，如果电机42的电机过度旋转，会使得新风管帽30的第一段31与新风管帽30的第二段32之间不能全部打开，从而可能导致在空调室内机处于新风模式时，摆叶41会降低室外新风的进风速度，从而会导致影响新风的进风量。
限制凸起303可以为圆环的四分之一。
在一种可选的方式中，限制凸起303设置有第一抵接边3031和第二抵接边3032。当新风管帽30的第一段31与新风管帽30的第二段32处于关闭状态时，摆叶41与限制凸起303的第一抵接边3031抵接；当新风管帽30的第一段31与新风管帽30的第二段32处于打开状态时，摆叶41与限制凸起303的第二抵接边3032抵接。
可选地，如图1和图2所示，空调室内机还包括橡胶圈50，橡胶圈50套设在新风管帽30的第一段31的外壁上，橡胶圈50位于墙壁安装孔的外侧，橡胶圈50用于密封墙壁安装孔。如此设置，可以覆盖新风管帽30与墙壁安装孔的孔壁之间的间隙，以避免室外的灰尘和杂质从新风管帽30与墙壁安装孔的孔壁之间的间隙进入室内。
其中，为了便于安装橡胶圈50，在新风管帽30的第一段31上设置有卡槽305。卡槽305的形状为圆环形。
本申请实施例还提供一种空调器，包括空调室外机以及空调室内机，空调室外机与空调室内机相互配合使用。
本实施例中的空调室内机与上述任一实施例提供的空调室内机的结构相同，并能带来相同或者类似的技术效果，在此不再一一赘述，具体可参照上述实施例的描述。
至此，已经结合附图所示的优选实施方式描述了本申请的技术方案，但是，本领域技术人员容易理解的是，本申请的保护范围显然不局限于这些具体实施方式。在不偏离本申请的原理的前提下，本领域技术人员可以对相关技术特征作出等同的更改或替换，这些更改或替换之后的技术方案都将落入本申请的保护范围之内。
