参照图1和图2，为本实用新型第三个实施例，该实施例基于前两个实施例。
具体的，主体组件200，包括风机本体201、显示屏202以及防护件203，显示屏202设置于风机本体201一侧，防护件203位于显示屏202外侧。
显示屏202用查看风机本体201的运行状态，此为现有技术，通过防护件203的设置，用于对显示屏202进行防护，避免显示屏202受到外力勿碰发生损坏的情况。
具体的，防护件203包括防护框203a以及铰接板203b，防护框203a设置于显示屏202一侧，铰接板203b固定于风机本体201一侧。
防护框203a通过铰接板203b与风机本体201铰接，防护框203a中心处为透明塑料材质，以此能够对显示屏202进行查看，当需要对显示屏202进行操 作时，将防护框203a向下翻转，使其与显示屏202分离，即可对显示屏202进行操作。
具体的，防护件203还包括支撑块203c、限位柱203d、固定块203e以及第二弹簧203f，支撑块203c固定于风机本体201一侧，限位柱203d插接于支撑块203c内，固定块203e固定于限位柱203d顶端，第二弹簧203f两端分别与支撑块203c和固定块203e固定。
防护框203a顶部开设有插孔，当限位柱203d插接于插孔内部时，便可对防护框203a进行限位，避免在使用时过程中防护框203a发生掉落，进而导致显示屏202裸露在外的情况，固定块203e用于对第二弹簧203f进行固定，通过第二弹簧203f的设置，用于对固定块203e施加一个向下的力，并通过固定块203e带动限位柱203d向下移动，使限位柱203d与插孔卡合的更为紧固，避免二者发生分离的情况。
在使用时，当需要对风机本体201的风量进行调节时，将活动套103f向下按压，使其带动定位板104a和限位销104b移动，并将限位销104b与限位孔Z分离，以此解除对活动套103f的限制，此时转动活动套103f带动定位杆103e转动，并通过定位杆103e带动蜗杆103b进行转动，蜗杆103b在转动时带动蜗轮103a进行转动，通过蜗轮103a带动连接轴102b转动，以此可使连接轴102b带动挡板102a进行翻转，从而能够对进风口的风量进行调节，当需要对显示屏202进行操作时，将限位柱203d向上拉动，使其与插孔分离，以此解除对防护框203a的限制，并将防护框203a向下翻转，使其与显示屏202分离，即可对显示屏202进行操作。
应说明的是，以上实施例仅用以说明本实用新型的技术方案而非限制，尽管参照较佳实施例对本实用新型进行了详细说明，本领域的普通技术人员应当理解，可以对本实用新型的技术方案进行修改或者等同替换，而不脱离本实用新型技术方案的精神和范围，其均应涵盖在本实用新型的权利要求范围当中。
