Description

防水驱动装置、散热风扇和鼓风机 技术领域
本申请涉及风扇技术领域，尤其涉及一种防水驱动装置、散热风扇和鼓风机。
背景技术
风扇是一种利用电动机驱动扇叶旋转，来促进空气加速流通以达到散热降温目的的装置。风扇的结构包括框体、转子、定子和扇叶，通过转子中的转轴与定子中的轴承相互枢接，从而使得转子上的扇叶相对于定子产生高速的旋转，以使得风扇周围产生一股强制气流，从而促进空气的流动，进而实现散热降温的效果。
但是在风扇运行过程中，转子需要相对于定子转动，所以转子与定子之间会存在一定的间隙。而由于间隙的存在，会使得水汽、液滴等物质进入到风扇内部，从而使得定子受到损坏而造成风扇无法正常运行。
通常市面上所说的防水散热风扇一般是指防护等级为IP53及以上的散热风扇，而且防护等级基本上不会超过IP56。现有技术中，为了提升风扇的防水性，一般是通过对风扇的定子进行真空镀膜或者浸三防漆，以避免水滴直接对风扇的定子产生危害。但是三防漆防水只是防水滴，比如不小心溅到水。对于具有一定湿度、水汽的场合，三防漆的防护效果将大打折扣。真空镀膜工艺是采用类似于半导体光刻技术，在真空环境下运用气相沉积的方式在物体表面沉积一层纳米材料。膜层厚度一般为5～30微米。镀膜工艺具有散热效果好、批量制造速度快等优点。但是纳米材料一般不抗腐蚀，膜层随时间会掉落，最高可以用于水蒸气环境。
由此，需要提高风扇的的防水等级，以适应更复杂环境的需求。

200、鼓风机；210、上壳体。
具体实施方式
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的一部分实施例，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 有做出创造性劳动的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。
参考图1至图2，本申请实施例提供的一种防水驱动装置100，包括：承载件110、驱动件和转动件120。承载件110包括框体111和设于框体111一侧上的盖体112，框体111和盖体112为一体成型结构；盖体112包括壳表面113，壳表面113围合以形成中空内腔，壳表面113具有与中空内腔连通的第一通孔和第二通孔116，框体111具有第三通孔，第三通孔与中空内腔连通；驱动件容置于中空内腔中，驱动件以用于驱动转动件120转动；转动件120套设于盖体112的外周侧壁上。
这样，通过将框体111和盖体112设置为一体成型结构，再将驱动件容置于盖体112的中空内腔中，一方面使得驱动件处于封闭的空间内，避免外界环境中的水侵袭驱动件，能够提高驱动件的防水性能，使得防水等级能够满足复杂环境的需要。且一体成型的结构装配工艺简单，可有效提高生产效率。另一方面，还可以提升承载件110的结构强度，进而提高防水驱动装置100的生产效率。
第一通孔、第二通孔116和第三通孔可以对应设置，这样便于利用冲压工艺将框体111和盖体112一次冲压成型。还可以设置第一通孔的开口直径与第三通孔的开口直径相等。第一通孔的开口直径大于第二通孔116的开口直径。
盖体112可以保护驱动件被水汽侵蚀，具体地，将驱动件容置于盖体112的中空内腔后，往盖体112的中空内腔中注入树脂，待树脂完全硬化后，盖体112和树脂便完全将驱动件密封起来，这样水汽不容易通过盖体112侵入到驱动件中，从而提高防水驱动装置100的防水等级，延长驱动件的使用寿命。
具体地，树脂通常是指受热后有软化或熔融范围，软化时在外力作用下有流动倾向，常温下是固态、半固态，有时也可以是液态的有机聚合物。在盖体112的中空内腔中注入树脂，一方面是考虑到树脂的可塑性强，可以适用于盖体112的不同形状。另一方面是由于树脂耐高温、耐腐蚀、且使用寿命长。当然，树脂可以使用环氧树脂，环氧树脂密封后的防水驱动装置100可以抗腐蚀，且可以用水冲击，防水效果好。
本申请提供的实施例，通过将盖体112和框体111设置为一体成型结构，还可以提高盖体112和框体111的生产效率。相比于现有技术中需要将盖体112和框体111分开生产，然后再利用粘接或焊接等方式将盖体112和框体111连接起来，本申请实施例提供的防水驱动装置100，只需要一次冲压成型，就可以完成盖体112和框体111的生产，明显提高了生产效率。
壳表面113为圆柱体结构，圆柱体结构包括第一圆柱部114和第二圆柱部115，第一圆柱部114与框体111连接，第二圆柱部115与第一圆柱部114连接；第一圆柱部114与第二圆柱部115围合以形成中空内腔，第二圆柱部115具有第二通孔116，第一圆柱部114的直径大于第二圆柱部115。
这样，通过设置第一圆柱部114的直径大于第二圆柱部115，将驱动件容置在中空内腔后，然后将树脂灌注到盖体112中，树脂填充满第一圆柱部114，从而使得盖体112的一端完全密封。将驱动件处于封闭环境，避免外面的异物进入，特别是可防止水侵入，避免造成驱动件被水腐蚀，造成短路。进而提高防水驱动装置100的防水性能。
设置壳表面113为圆柱体结构，也能够减小框体111的体积，使得防水驱动装置100朝向小型化方向发展，更便于日常生活中使用。
第三通孔的开口直径与第一圆柱部114的开口直径相等。设置第三通孔的开口直径与第一圆柱部114的开口直径相等，即第三通孔的开口直径与第一通孔的开口直径相等，可以便于框体111和盖体112的一体成型，提高生产效率。
转动件120包括安装座和扇叶，扇叶设置在安装座的周侧，安装座具有内腔，且安装座的一端设有开口，安装座套设在盖体112的外周侧壁上。安装座转动时，扇叶跟随安装座转动，扇叶设置在安装座的周侧，进而使得防水驱动装置100的结构设置更加紧凑。多个扇叶间隔均匀的设置在安装座的周侧，以使得转动件120的周围可以形成稳定且均匀的空气流动。
转动件120还包括磁体和转动轴，磁体设置在安装座的外周侧壁上，转动轴与安装座固定连接，且转动轴设置在内腔中，转动轴贯穿第二通孔116；驱动件驱动转动轴转动。转动轴的外径与第二通孔116的孔径大小基本接近，这样可以避免水汽从第二通孔116进入到驱动件中。也可以使得驱动件平稳地驱动转动轴转动。
磁体包括永磁体。永磁体是一种能够长期保持磁性的磁体。将永磁体应用于防水驱动装置100中，可以延长转动件120的使用寿命。
驱动件只要可以驱动转动件120转动即可，驱动件可以为电机。当然，驱动件也可以为马达。
框体111由塑料材质制成。塑料制成的框体111，一方面可以节约成本，另一方面还可以减轻防水驱动装置100的重量，使得防水驱动装置100易于搬运或转移。当然，框体111还可以由矽钢材料制成，这样可以提高转动件120的稳定性，使得驱动件平稳且均匀的驱动转动件120转动。
综上所述，本申请实施例提供的防水驱动装置100，能够满足使用环境恶劣(水、盐雾、油污等)，以及热传导和热辐射不能满足散热需求的场景。利用本申请实施例提供的防水驱动装置100，通过设置框体111和盖体112为一体成型结构，再将驱动件放置于盖体112的中空内腔中，然后利用树脂进行密封，从而提高防水驱动装置100自身的防护性能，保证防水驱动装置100在极端的环境下能长时间稳定的运行。
本申请实施例还提供一种散热风扇，包括防水驱动装置100。将防水驱动装置100应用于散热风扇，能够适应水汽环境下使用，使得散热风扇的防水等级进一步提高。散热风扇可满足用户在沙漠、极地、高山、海边等恶劣环境中长时间稳定使用，提供高效能的散热和防水级别。
参考图3至图5，本申请实施例还提供一种鼓风机200，包括防水驱动装置100。将防水驱动装置100应用于鼓风机200，能够适应水汽环境下使用，使得鼓风机200的防水等级进一步提高。鼓风机200的作用是较为准确的输送一定风量，一般用于锅炉等助燃送风用，或者用于厕所或浴室等吹干地板。。
鼓风机200还包括上壳体210，上壳体210与承载件110可拆卸连接。上壳体210与承载件110可以为螺纹连接，或者上壳体210与承载件110之间通过焊接进行连接。上壳体210可以由塑料材质制成，也可以选用其他材料制成，例如不锈钢材料。
需要说明的是，在本文中，诸如“第一”和“第二”等之类的关系术语仅仅用来将一个实体或者操作与另一个实体或操作区分开来，而不一定要求或者暗示这些实体或操作之间存在任何这种实际的关系或者顺序。而且，术语“包括”、“包含”或者其任何其他变体意在 涵盖非排他性的包含，从而使得包括一系列要素的过程、方法、物品或者设备不仅包括那些要素，而且还包括没有明确列出的其他要素，或者是还包括为这种过程、方法、物品或者设备所固有的要素。在没有更多限制的情况下，由语句“包括一个……”限定的要素，并不排除在包括所述要素的过程、方法、物品或者设备中还存在另外的相同要素。
以上所述仅是本发明的具体实施方式，使本领域技术人员能够理解或实现本发明。对这些实施例的多种修改对本领域的技术人员来说将是显而易见的，本文中所定义的一般原理可以在不脱离本发明的精神或范围的情况下，在其它实施例中实现。因此，本发明将不会被限制于本文所示的这些实施例，而是要符合与本文所申请的原理和新颖特点相一致的最宽的范围。
