Description

一种风扇
【技术领域】
本发明涉及家用电器领域， 更具体的说， 涉及一种风扇。 【背景技术】
本人设计了一种风扇， 包括壳体、 用于挂起风扇的挂绳以及放置在壳体内 的电路板、 风扇装置和电池等， 壳体设有进风口和出风口， 壳体包括前壳和与 前壳进行卡接固定的后壳， 其中进风口设置在前壳上， 出风口设置在壳体顶部 或底部。 风扇在前壳的进风口处设置保护件， 用于保护风扇内的器件以及防止 手指伸入， 但是保护件是直接在前壳上设置和前壳一体成型， 这样就不方便设 置， 又由于进风口设置较大， 从而使设置保护件的保护作用不太好。
【发明内容】
本发明所要解决的技术问题是提供一种在进风口处设置保护件保护效果好 且方便设置的风扇。
本发明的目的是通过以下技术方案来实现的： 一种风扇， 包括前壳、 设置 在前壳上的进风口以及设置在进风口处的保护件， 所述保护件为固定在前壳上 的保护网。
优选的， 所述保护网通过卡接固定在前壳上。 卡接方便拆卸、 容易固定。 优选的， 所述前壳在进风口边沿处设有卡扣， 对应的保护网设有与卡扣配 合的卡孔或卡槽。 这是卡接的一种具体方式。
优选的， 所述进风口为圓形， 所述保护网为圓环形。 圓形结构容易生产、 方便配合。
优选的， 所述保护网包括设置在中心的中心件和与中心件通过连接件连接 的环形件。 这是保护网的具体结构。
优选的， 所述连接件至少为两个且均布在中心件和环形件之间。 连接件把 进风口分成许多份小块， 从而增加保护效果。
优选的， 所述中心件为圓形。 这样设置方便生产和配合， 而且可增加保护 件中心的强度。
优选的， 所述中心件外表面设有向内凹陷的圓形的凹槽， 所述凹槽至少为 三个且等间隔设置。 这是设置中心件的一种具体结构。
优选的， 所述连接件呈 S形， 所述环形件为圓环形， 所述中心件向内凹陷。 将连接件设置成 S形， 使中心件向内凹陷， 从而对中心件起到保护作用， 减少 中心件和连接件与外界的接触。
优选的， 所述卡孔设置在环形件上。
本发明由于在风扇的前壳进风口处设置保护网防止杂物或其它从进风口处 进入风扇内， 尤其是防止使用者的手指； 由于保护网和前壳是分离的， 保护网 直接固定在前壳的进风口处， 可以通过卡接固定、 螺丝固定或其它固定方式， 而保护网单独生产就叫容易实现， 保护网可以制作的更加精密， 起到的保护作 用更佳， 并且也方便和前壳配合固定。 【附图说明】
图 1是本发明实施例所述保护网的结构示意图；
图 2.是本发明实施例所述前壳的结构示意图；
其中： 1、 中心件； 11、 凹槽； 2、 连接件； 3、 环形件； 31、 卡孔； 4、 卡 扣。
【具体实施方式】
下面结合附图和较佳的实施例对本发明作进一步说明。
本发明公开一种风扇， 包括前壳、 设置在前壳上的进风口以及设置在进风 口处的保护件， 如图 1和图 2所示， 所述保护件为固定在前壳上的保护网。
本发明由于在风扇的前壳进风口处设置保护网防止杂物或其它从进风口处 进入风扇内， 尤其是防止使用者的手指； 由于保护网和前壳是分离的， 保护网 直接固定在前壳的进风口处， 可以通过卡接固定、 螺丝固定或其它固定方式， 而保护网单独生产就叫容易实现， 保护网可以制作的更加精密， 起到的保护作 用更佳， 并且也方便和前壳配合固定。
在本实施例中， 所述保护网通过卡接固定在前壳上， 卡接方便拆卸、 容易 固定， 具体的所述前壳在进风口边沿处设有卡扣 4, 对应的保护网设有与卡扣 4 配合的卡孔 31 , 这是设置卡接的一种方式， 当然也可以在前壳进风口边沿设置 卡孔， 在保护网上设置与卡孔配合的卡扣， 从而实现卡接配合， 能够起到同样 的有益效果。 所述卡扣 4和卡孔 31都设置为至少两个， 具体的可以设置三个、 四个、 五个或其它， 而且卡扣 4和卡孔 31都是均布设置的， 从而使其受理均匀 使固定效果更佳。 本实施例卡孔可用卡槽代替可以起到同样的效果。
在本实施例中， 所述进风口为圓形， 所述保护网为圓环形， 由于进风口为 圓形， 保护网这样设置配合进风口使配合更好， 所述保护网包括设置在中心的 中心件 1和与中心件 1通过连接件 2连接的环形件 3 , 中心件 1、 连接件 2和环 形件 3三者一体设置形成保护件， 所述连接件 2至少为两个且均布在中心件 1 和环形件 3之间， 连接件 2把进风口分成许多份小块， 从而增加保护效果。
为了方便设置和配合， 所述中心件 1为圓形， 所述环形件 3为圓环形， 所 述卡孔 31设置在环形件 3上， 这样方便和前壳进行配合。
在本实施例中， 所述中心件 1外表面设有向内凹陷的圓形的凹槽 11 , 所述 凹槽 11至少为三个且等间隔设置， 这样设置可节省材料， 而且使保护网美观， 提高观赏价值。
在本实施例中， 所述连接件 2呈 S形， 所述环形件 3为圓环形， 所述中心 件 1向内凹陷， 将连接件 2设置成 S形， 使中心件 1向内凹陷， 从而对中心件 1 起到保护作用， 减少中心件 1和连接件 2与外界的接触。
以上内容是结合具体的优选实施方式对本发明所作的进一步详细说明， 不 能认定本发明的具体实施只局限于这些说明。 对于本发明所属技术领域的普通 技术人员来说， 在不脱离本发明构思的前提下， 还可以做出若干简单推演或替 换， 都应当视为属于本发明的保护范围。
