本实用新型提供了一种电子设备300，包括本实用新型提供的所述防尘组件100和设备单元200（微型投影设备）。所述防尘组件100与所述设备单元200形成可拆卸连接。
具体的，所述设备单元200包括机壳201、电子器件（图未示）、散热风道（图未示）及风扇202。
所述机壳201具有收容空间203，所述机壳201上分别开设有用于散热的出风口2011和进风口2012。本实施方式中，所述出风口2011开设于所述机壳201的投影侧，所述进风口2012设于所述机壳201的另外相对两侧。所述进风口2012与所述出风口2011位于所述机壳201的不同侧为宜，散热效果更好。
所述防尘组件100可相对于所述机壳201进行拆卸，即二者为可拆卸连接，以便对所述电子设备300进行维护。
所述电子器件固定于所述机壳201内，即收容于所述收容空间203内，所述电子器件即为所述设备单元200的工作器件，比如，本实施方式中，所述设备单元200为微型投影设备，则所述电子器件包括用于形成投影的投影器件，如电路单元及光源等，用于形成光学投影在投幕上进行显示。
所述散热风道形成于所述机壳201内，即形成于所述收容空间6内，用于进行空气流通，从而实现热交换以完成所述电子设备300的散热。所述散热风道一端与所述进风口2012连通，另一端与所述出风口2011连通。

更优的，所述固定壁102与所述后盖101垂直设置，形成一整体结构。本实施方式中，所述后盖101与所述固定壁102为一体注塑成型。
也就是说，当将所述防尘组件100的所述后盖101从所述设备单元200上进行拆卸时，所述固定壁102则同时与所述后盖101一起被拆卸下来，可减少维护时拆装工序，提高效率。
所述防尘过滤网103安装于所述固定壁102上。具体的，所述防尘过滤网103卡设固定于所述固定壁102且完全覆盖所述通孔1021，用于对进风时的冷空气进行灰尘类的颗粒物过滤，以防止灰尘等颗粒物进入所述散热风道，避免了因灰尘等颗粒物在所述散热风道内累积后使空气交换效果变差甚至堵塞的现象，提高了所述电子设备300的散热性能和使用寿命。
    因所述固定壁102的所述通孔1021设计呈栅栏结构或网格结构排布，当所述防尘过滤网103固定于所述固定壁102时，其栅栏结构或网格结构的设计对所述防尘过滤网103形成支撑作用，使得所述防尘过滤网103的固定效果更好，性能更稳定。
更优的，所述防尘过滤网103卡设于所述固定壁102的内侧，即所述固定壁102的面向所述机壳201的一侧，该结构设置可使所述固定壁102对所述防尘过滤网103进行保护，防止所述防尘过滤网103裸露在外被损坏。
当然，所述防尘过滤网103卡设于所述固定壁102的外侧，即远离所述机壳201的一侧也是可行的，或者通过其它固定结构装配后形成组件，再共同固定于所述固定壁102，这也是可行的，其原理都一样。
所述防尘过滤网103固定于所述固定壁102的方式不限，本实施方式中，将所述防尘过滤网103卡设于所述固定壁102形成固定，该结构设置可方便快捷的使所述防尘过滤网103从所述固定壁102进行拆装。比如，所述固定壁102设有由其内侧（面向所述机壳201的一侧）向外侧（远离所述机壳201的一侧）方向凹陷的收容槽1022，所述防尘过滤网103卡设于所述收容槽1022内形成固定的形式实现，当然，也可以通过其它固定方式，也是可行的。
因所述固定壁102与所述后盖101为一体结构，当需要维护时，将所述后盖101从所述设备单元200上进行拆卸时，所述固定壁102也被一起拆卸，而卡设于所述固定壁102上的所述防尘过滤网103也被同时从所述设备单元200拆卸，再通过其卡设固定的结构使得所述防尘过滤网103被快速拆卸，方便对其清洁、更换或其它维护，提高了维护效率。
上述设备单元200仅以微型投影设备为优选实施例进行说明，即仅对所述防尘组件100运用于微型投影设备进行了说明。但所述防尘组件100并不限于适用此范围，还可运用于其它场合的设备单元，比如所述设备单元200为其它型的投影设备，如工程投影机，或者所述设备单元200为笔记本电脑、机顶盒等，这都是可行的，其原理与所述防尘组件100运用于所述微型投影设备的原理一样。
与现有技术相比，本实用新型的防尘组件设置了后盖及与后盖固定连接的固定壁，同时设置了卡设固定于所述固定壁的防尘过滤网，卡设固定结构使得所述防尘过滤网拆卸方便，维护时效率高；当所这防尘组件运用于所述设备单元时，其与所述设备单元的机壳形成可拆卸连接，并使所述固定壁盖设于所述进风口，从而对散热风道进行了防尘保护，保证了其散热效率，提高了所述电子设备的使用寿命；所述防尘过滤网卡设于所述固定壁，因所述固定壁与所述后盖为一体结构，因此，所述防尘过滤网可随所述后盖拆卸实现同时拆卸，方便后期的维护。
需要说明的是，以上参照附图所描述的各个实施例仅用以说明本实用新型而非限制本实用新型的范围，本领域的普通技术人员应当理解，在不脱离本实用新型的精神和范围的前提下对本实用新型进行的修改或者等同替换，均应涵盖在本实用新型的范围之内。此外，除上下文另有所指外，以单数形式出现的词包括复数形式，反之亦然。另外，除非特别说明，那么任何实施例的全部或一部分可结合任何其它实施例的全部或一部分来使用。
