进风组件及空气净化装置
相关申请
本申请要求2018年10月11日申请的，申请号为201811184968.9，名称为“一种进风组件及空气净化装置”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及空气净化器技术领域，尤其涉及一种进风组件及空气净化装置。
背景技术
空气净化器是指能够吸附、分解或转化各种空气污染物，有效提高空气清洁度的电器，其通常具有检测空气质量的传感器，如粉尘传感器等。目前空气净化器中的粉尘传感器多置于整机底部或进风壳体内部，因粉尘传感器使用一段时间后需要定期用棉签等清洁，若在整机底部或进风壳体内部，则用户清洁不便；若将粉尘传感器安装在出风框处则又靠近出风口，检测到的数值更接近出风口处的PM2.5数值，不能真实反映未净化的整个空间内的PM2.5状况。
因此，如何设计一种便于清洁、装配简单的进风组件是业界亟待解决的技术问题。
发明内容
为了解决传统的空气净化装置存在不便于清洁的缺陷，本申请提出一种进风组件及空气净化装置。
本申请采用的技术方案是，设计一种进风组件，包括：进风壳体和传感器，进风壳体的外侧面设有第一固定结构，传感器安装在第一固定结构中。
在其中一个实施例中，第一固定结构靠近进风壳体的进风口。
在其中一个实施例中，进风壳体包括：风道和组装在风道的进风口的进风支架。
在其中一个实施例中，进风壳体的外侧还设有开关件，开关件包含安装块和与安装块连接的按压块。
在其中一个实施例中，风道和进风支架其中一个的外侧面设有第一固定结构、另一个的外侧面设有第二固定结构，安装块配合安装在第一固定结构和第二固定结构之间。
在其中一个实施例中，风道的外侧面设有第一固定结构，进风支架的外侧面设有第二 固定结构。
在其中一个实施例中，第一固定结构一体化设置在风道上。
在其中一个实施例中，第二固定结构一体化设置在进风支架上。
在其中一个实施例中，第一固定结构设有定位传感器的第一定位部和固定传感器的固定部。
在其中一个实施例中，第一定位部包含若干个内筋条和外筋条，传感器的一面贴合在内筋条上，外筋条围设在传感器的周边。
在其中一个实施例中，固定部为螺柱，传感器上设有与螺柱配合的安装孔。
在其中一个实施例中，第二固定结构设有定位安装块的第二定位部，第一固定结构设有将安装块压紧在第二定位部中的抵接部。
在其中一个实施例中，第一固定结构设有定位安装块的第二定位部，第二固定结构设有将安装块压紧在第二定位部中的抵接部。
在其中一个实施例中，第二定位部为与安装块形状配合的容纳槽，容纳槽由若干个支撑筋条和定位筋条构成，安装块夹持在支撑筋条和抵接部之间，定位筋条围设在安装块的周边。
在其中一个实施例中，第二定位部为与安装块配合卡接的卡扣。
在其中一个实施例中，第二定位部为定位柱，安装块上设有容纳定位柱插入的插槽。
在其中一个实施例中，第二定位部为插槽，安装块上设有插入插槽中的定位柱。
在其中一个实施例中，传感器为粉尘传感器。
在其中一个实施例中，传感器还连接有用于显示空气质量的显示装置。

3、开关件通过第一固定结构和第二固定结构进行安装，使得整机的结构更加小巧紧凑。
附图说明
为了更清楚地说明本申请实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本申请的实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据公开的附图获得其他的附图。
图1是本申请一实施例的进风组件的外侧面示意图；
图2是本申请一实施例的进风组件的剖面示意图。
具体实施方式
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，所描述的实施例仅仅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做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。
如图1和图2所示，本申请一实施例提出的进风组件包括：进风壳体和传感器1，传感器1为粉尘传感器或其他可以检测空气质量的传感器，进风壳体的外侧面设有第一固定结构2，传感器1安装在第一固定结构2中，第一固定结构2靠近进风壳体的进风口，使得传感器1的检测数值更接近其所在环境的空气质量，传感器1还连接有用于显示空气质量的显示装置，传感器1的检测数值可通过显示装置进行显示。
在一实施例中，进风壳体包括：风道3和组装在风道3的进风口的进风支架4。在一实施例中，进风壳体的外侧还设有开关件，开关件5为微动开关或其他开关，开关件5包含安装块51和与安装块51连接的按压块52。在一实施例中，风道3和进风支架4其中一个的外侧面设有第一固定结构2、另一个的外侧面设有第二固定结构6，安装块51配合安装在第一固定结构2和第二固定结构6之间。在一实施例中，第一固定结构2设置在风道3的外侧面，进风支架4的外侧面设有第二固定结构6，第一固定结构2一体化设置在风道3上，第二固定结构6一体化设置在进风支架4上，通过将固定结构与现有零件设计为一体，实现优化空间利用，结构更紧凑、装配更方便，有效降低生产成本。
在一实施例中，第一固定结构2设有定位传感器1的第一定位部21和固定传感器1的固定部22，第一定位部21包含若干个内筋条和外筋条，传感器1的一面贴合在内筋条上，外筋条围设在传感器1的周边，固定部22为螺柱，传感器1上设有与螺柱配合的安装孔。第二固定结构6设有定位安装块51的第二定位部61，第一固定结构2设有将安装块51压紧在第二定位部61中的抵接部23。当然，在可行实施例中，也可以将第二定位部61设置在第一固定结构2上，将抵接部23设置在第二固定结构6上。
可选地，第二定位部61的结构有多种选择。在一实施例中，第二定位部61设计为与安装块51形状配合的容纳槽，容纳槽由若干个支撑筋条和定位筋条构成，安装块51夹持在支撑筋条和抵接部23之间，定位筋条围设在安装块51的周边，以第一种结构为例，安装时先将传感器1初步定位在第一定位部21中，再通过螺钉将传感器1固定在螺柱上，再将安装块51放置在容纳槽中，然后将风道3和进风支架4组装在一起，此时抵接部23将安装块51压紧在容纳槽中，当然实际操作时也可以先安装块51再安装传感器1。在另一实施例中，第二定位部61设计为与安装块51配合卡接的卡扣。在另一实施例中，第二定位部61设计为定位柱，在安装块51上设置容纳定位柱插入的插槽。在另一实施例中，第二定位部61设计为插槽，在安装块51上设置插入插槽中的定位柱。
本申请还提出了一种空气净化装置，包括上述的进风组件。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。
对所公开的实施例的上述说明，使本领域专业技术人员能够实现或使用本申请。对这些实施例的多种修改对本领域的专业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申请的精神或范围的情况下，在其它实施例中实现。因此，本申请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公开的原理和新颖特点相一致的最宽的范围。
