具体实施方式
在相关技术的方案中，具有新风装置的空调内机需要通过新风管与外界空气连通；在安装时，需要在墙体上开设通孔，新风管穿过该通孔后连接外界空气。一般的，在墙体上开设的通孔的直径略大于新风管的 直径，新风管安装后与通孔之间会形成一定的间隙；为了室内侧美观、防止昆虫或空气中的杂质进入室内，在新风管的外侧还套设有护套，护套安装在室内侧的墙体上以遮挡新风管与通孔之间的间隙。但是，采用上述相关技术的方案，护套一般是直接放置在通孔内的，使用一段时间后易脱落(例如，当新风管被移动时会带动护套一起移动，从而可能造成护套的脱落)，护套脱落后会将新风管与通孔之间的部分间隙显露出，影响室内侧的美观性、且存在昆虫或空气中的杂质进入室内的风险。
有鉴于此，本申请旨在提供一种新风管组件、空调内机及空调器，通过在护套本体上设置多个弹性臂，弹性臂的第一端与本体固定连接，弹性臂的第二端为自由端，弹性臂背离本体一侧的表面上设有防脱落结构。在使用时，可以利用设置在护套的本体的一端上的凸缘将新风管与墙体上的通孔之间的间隙遮蔽住，本体上的弹性臂可以抵接在通孔的内壁上，弹性臂表面的防脱落结构能够增加本体与通孔之间的摩擦力，从而防止护套的掉落。
为使本申请实施例的目的、技术方案和优点更加清楚，下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
实施例一
图1是本申请一实施例提供的新风管组件的结构简图；图2是本申请一实施例提供的护套的结构简图；图3是本申请一实施例提供的护套的剖视图；图4是本申请一实施例提供的护套与墙体之间的连接结构简图；图5是本申请另一实施例提供的护套与墙体之间的连接结构简图；图6是本申请再一实施例提供的护套与墙体之间的连接结构简图。
请参照图1-图6，本实施例提供了一种新风管组件，包括：
新风管100，新风管100用于穿设在墙体10上的通孔11内。新风 管100例如可采用波纹管，新风管100自身具有一定的弹性，从而便于根据实际安装需要进行拉伸。
护套200，护套200套设在新风管100上，且用于固定在通孔11内，护套200位于墙体11朝向室内的一侧。护套200包括本体210及设置在本体210一端的凸缘220。本体210呈圆柱状，内部形成有贯穿本体210的通道，本体210可套设在新风管100上。凸缘220可以将本体210与通孔11之间的间隙遮蔽住，从而防止昆虫或空气中的杂质进入室内，提高室内侧的美观性。本体210背离新风管100的一侧设有多个弹性臂230，弹性臂230的第一端与本体210固定连接，弹性臂230的第二端为自由端；弹性臂230可以依靠自身材质而具有一定的弹性，弹性臂230例如可以选用钢板、硬质塑料等材质。可选地，整个护套200可以采用一体成型的方式制备而成，从而有利于提高生产效率。弹性臂230背离本体210一侧的表面上设有防脱落结构，防脱落结构可以增大弹性臂230与通孔11的内壁之间的摩擦力。
本实施例的新风管组件可以利用设置在本体210的一端上的凸缘220将新风管100与通孔11之间的间隙遮蔽住，本体210上的弹性臂230可以抵接在通孔11的内壁上，弹性臂230表面的防脱落结构能够增加本体210与通孔11之间的摩擦力，从而防止护套200的掉落。
在一种可能的实施方式中，本实施例的弹性臂230的第一端背离凸缘220设置，弹性臂230的第二端与本体210之间形成有间隙。这样设置可以使得安装时弹性臂230被通孔11挤压而顺利的进入通孔11内，并且进入后弹性臂230在自身弹性力的作用下保持与通孔11的抵接，从而可以防止本体210从通孔11内脱落。
在一种可能的实施方式中，本实施例的弹性臂230包括第一连接部231、第二连接部232和抵接部233，抵接部233位于弹性臂230的第二端，抵接部233的两端分别连接第一连接部231的第二端和第二连接部232的第二端，第一连接部231的第一端和第二连接部232的第一端均连接本体210。第一连接部231、第二连接部232和抵接部233共同组 成一个类似“U”型的结构，由于本体210与通孔11的内壁均是圆弧面，弹性臂230与通孔11接触时各点的位置不在同一平面内，将弹性臂230设置成上述结构，第一连接部231和第二连接部232可以平衡弹性臂230的受力情况，有利于延长弹性臂230的使用寿命。
进一步地，本实施例的防脱落结构包括设置在第一连接部231上的第一防脱落结构241和设置在第二连接部232上的第二防脱落结构242；第一防脱落结构241与第二防脱落结构242可以相同，也可以不同。
具体的，第一防脱落结构241包括多个沿第一连接部231的延伸方向设置的第一凸起，第一凸起自第一连接部231的第一端向第一连接部231的第二端倾斜设置。在背离第一连接部231的方向上，第一凸起逐渐缩小，从而形成类似“倒刺”的结构，以增大与通孔11的内壁之间的摩擦力。
同样的，第二防脱落结构242包括多个沿第二连接部232的延伸方向设置的第二凸起，第二凸起自第二连接部232的第一端向第二连接部232的第二端倾斜设置。在背离第二连接部232的方向上，第二凸起逐渐缩小，从而形成类似“倒刺”的结构，以增大与通孔11的内壁之间的摩擦力。
可选地，如图2和图3所示，在垂直于弹性臂230的平面内，本实施例的第一凸起和第二凸起均呈三角形，也即第一防脱落结构241与第二防脱落结构242均呈“锯齿状”。
如图2所示，本实施例中本体210上设有四个弹性臂230，四个弹性臂230沿本体210的周向均匀分布。可以理解的是，在其他可能的实施方式中，本体210上的弹性臂230的具体数量可以根据需要进行设置，例如还可以是三个、五个或六个等，本实施例对此不做限定。
本实施例由于在本体210上设置了弹性臂230，因此能够适用于一定范围内不同孔径的通孔11，只要能够保持弹性臂230与通孔11的内壁之间具有一定的抵接力即可。
例如，如图4所示，当通孔11的直径较大时，本体210上的弹性 臂230的自由端可以抵接在通孔11的内壁上，此时依靠抵接部233以及靠近抵接部233的部分第一防脱落结构241和第二防脱落结构242的作用，本体210可以稳定的安装在通孔11内。
又如，如图5所示，此时通孔11的直径比图4中所示的通孔直径较小，弹性臂230相较于图4所示情况被进一步压缩，弹性臂230依然抵接在通孔11的内壁上，依靠中部的部分第一防脱落结构241和第二防脱落结构242的作用，本体210可以稳定的安装在通孔11内。
再如，如图6所示，此时通孔11的直径比图5中所示的通孔直径较小，弹性臂230相较于图5所示情况被进一步压缩，弹性臂230依然抵接在通孔11的内壁上，依靠靠近本体210的部分第一防脱落结构241和第二防脱落结构242的作用，本体210可以稳定的安装在通孔11内。
在一种可能的实施方式中，本实施例的新风管组件还包括：
风帽300，风帽300连接在新风管100的第一端，且位于墙体11朝向室外的一侧；风帽300的侧壁上设有多个通风孔310，使用时通风孔310优选朝向地面一侧设置，以防止雨水从通风孔310流入新风管100内。
密封橡胶圈400，密封橡胶圈400套设在风帽300上，密封橡胶圈400用于抵接在墙体10位于室外的一侧，从而防止杂物进入通孔11内。
连接件500，连接件500设置在新风管100的第二端，连接件500用于连接新风装置。可选地，连接件500的周向方向上可以设置多个连接孔，可以利用卡接等方式与新风装置实现连接固定。
护网600，护网600设置在新风管100内，用于防止空气中颗粒较大的杂质或树叶等杂质进入新风装置。
综上，本实施例的新风管组件可以利用设置在本体210的一端上的凸缘220将新风管100与通孔11之间的间隙遮蔽住，本体210上的弹性臂230可以抵接在通孔11的内壁上，弹性臂230表面的防脱落结构能够增加本体210与通孔11之间的摩擦力，从而防止护套200的掉落。
实施例二
本实施例提供一种空调内机，包括机壳，机壳内设有新风装置，新风装置通过如上实施例一的新风管组件连接室外空气。
本实施例的空调内机由于通过上述实施例一的新风管组件实现与室外空气的连通，因此在使用时新风管的护套不易从墙体的通孔上脱落，从而有利于提高室内的美观性。
实施例三
本实施例提供一种空调器，包括互相连接的空调内机和空调外机，空调内机采用如上的空调内机。
本实施例的空调器由于采用了上述实施例二的空调内机，因此在使用时新风管的护套不易从墙体的通孔上脱落，从而有利于提高室内的美观性。
