Abstract

一种吸尘器（100），包括壳体（110）、滤网（120）及螺旋导风件（130）。螺旋导风件（130）设于排风通道内并位于滤网（120）进风侧及出风侧的至少一侧，流经排风通道的气流在螺旋导风件（130）的导流作用下形成旋转气流。启动工作时，夹带杂质的气流经进风口（111）、进风通道（112）进入集尘腔，气流中的杂质被滤网（120）阻隔从而留在集尘腔内，而剩余的尾气则经排风通道由排风口（113）排出。气流在螺旋导风件（130）的作用下旋转，流经排风通道的气流并非直吹向滤网（120）。因此，气流中的杂质也不会垂直撞向滤网（120），而是具有横向的速度，故不易附着于滤网（120）。而且，旋转气流还能形成扰动，从而将吸附于滤网（120）表面的杂质卷起，能够进一步防止杂质在滤网（120）的表面堆积。因此吸尘器（100）在工作时能有效地避免滤网（120）堵塞。

Description

吸尘器 技术领域
本实用新型涉及清洁用品技术领域，特别涉及一种吸尘器。
背景技术
吸尘器是一种常见的清洁工具，一般包括壳体、吸头、废料盒、滤网及电机等元件。电机工作可产生负压，从而将粉尘、碎屑等杂质经吸头吸入壳体并进入废料盒。经过滤网的过滤，碎屑留在废料盒内，而尾气则由排气通道排出。
由于吸尘器内的气流流速极快，故裹挟在气流中的粉尘、碎屑将会高速撞向滤网并吸附于滤网的表面。而且，在吸尘器的使用过程中，滤网两侧一直存在压力差，故附着在滤网上的杂质将会不断堆积，并最终导致滤网被堵塞而无法正常使用吸尘器。
实用新型内容
基于此，有必要针对现有吸尘器的滤网在使用过程中容易堵塞的问题，提供一种能够有效地防止滤网堵塞的吸尘器。
一种吸尘器，包括：
壳体，设有进风口、进风通道、排风通道、排风口及集尘腔，所述集尘腔通过所述进风通道及所述排风通道分别与所述进风口及所述排风口连通；
滤网，设于所述排风通道内；及
螺旋导风件，设于所述排风通道内并位于所述滤网进风侧及出风侧的至少一侧，流经所述排风通道的气流在所述螺旋导风件的导流作用下形成旋转气流。
在其中一个实施例中，所述进风通道及所述排风通道与所述集尘腔的同一侧相连通，并与所述集尘腔配合形成U形腔体结构。

上述吸尘器，启动工作时，夹带杂质的气流经进风口、进风通道进入集尘腔，气流中的杂质被滤网阻隔从而留在集尘腔内，而剩余的尾气则经排风通道由排风口排出。气流在经过螺旋导风件时，将在螺旋导风件的作用下旋转气流。也就是说，流经排风通道的气流并非直吹向滤网。因此，气流中的杂质也不会垂直撞向滤网，而是具有横向的速度，故不易附着于滤网。而且，旋转气流还能形成扰动，从而将吸附于滤网表面的杂质卷起，能够进一步防止杂质在滤网 的表面堆积。因此，上述吸尘器在工作时能有效地避免滤网堵塞。

请参阅图1至图3，本实用新型较佳实施例中的吸尘器100包括壳体110、滤网120及螺旋导风件130。
壳体110一般由塑料、树脂等材质成型，其上形成有供握持的把手(图未标)。壳体110设有进风口111、进风通道112、排风通道(图未示)、排风口113 及集尘腔(图未示)，集尘腔通过进风通道112及排风通道分别与进风口111及排风口113连通。
滤网120设于排风通道内。滤网120可通过卡扣等结构安装于排风通道的内壁，方便拆装。滤网120可以是纸质的一次性滤网，在堵塞或污染时可直接替换。滤网120也可是塑料滤网，可在堵塞或污染时进行清洗。滤网120允许气体通过，但会阻止较大的颗粒通过。
显然，为实现吸尘，吸尘器100还包括用于产生吸力的驱动电机(图未示)，驱动电机收容并固定于壳体110内。驱动电机启动工作时，将在进风通道112内形成负压，夹带杂质的气流经进风口111、进风通道112进入集尘腔，气流中的杂质被滤网120阻隔从而留在集尘腔内，而剩余的尾气则经排风通道由排风口113排出。
集尘腔可开启，当集成腔内收集的杂质达到最大允许容量(即，集尘腔满载)后，可开启集尘腔并对其收集的杂质进行清理。
具体在本实施例中，吸尘器100还包括可拆卸地安装于壳体110的集尘盒140，集尘盒140为一侧开口的中空结构并与壳体110配合形成集尘腔。
集尘盒140的材质可与壳体110的材质相同，也可是方形或圆形的中空结构。通常情况下，集尘盒140通过卡扣与壳体110实现安装。在集尘腔满载时，可将集尘盒140取下进行杂质清理。同时，集尘盒140拆下后，集成腔被开启，排风通道及滤网120被暴露出来，如此一来还可方便对滤网120进行拆换或清洗。
进一步的，在本实施例中，集尘盒140的底部设有可开启的盖板141。盖板141可通过转轴、铰链与集尘盒140连接。在需要清理集尘盒140内的杂质时，无需将集尘盒140从壳体110上拆下，开启盖板141即可，操作更方便。
此外，为了避免集成腔开启时，因误触而将驱动电机意外启动，从而带来安全隐患。具体在本实施例中，吸尘器100还包括与驱动电机电连接的触发开关150，且在集尘腔处于开启状态时，触发开关150使驱动电机处于断电状态。
触发开关150可设于集尘盒140与壳体110之间，也可设置在盖板141上。当集尘盒140满载需要进行杂质清洗时，可将集尘盒140从壳体110拆下，或将盖板141打开。此时，触发开关150将使驱动电机处于断电状态。因此，即使发生误触，也不会将驱动电机启动，从而提高了吸尘器100的安全性。
进一步的，在本实施例中，集尘盒140具有至少一个透明侧壁。集尘盒140可整体由透明材料成型，也可将其中一个或多个侧壁采用透明板材替代。通过设置透明侧壁，能够对集尘腔的内部实时进行观察。如此，集尘盒140内一旦满载，用户便可及时发现从而能够及时进行清理。而且，通过透明的侧壁还能对滤网120的状态进行观察，以判断滤网120是否堵塞。
具体在本实施例中，集尘盒140的侧壁由导光材料成型，故集尘盒140整体可实现导光。此外，为了对集尘盒140的装载情况、滤网120是否堵塞等吸尘器100的状态实现指示。具体在本实施例中，吸尘器100还包括状态指示灯160。状态指示灯160在满足触发条件时发出指示光线，且指示光线可传导至集尘盒140的侧壁。
触发条件可以是发生集尘盒140满载、滤网120堵塞等情况。指示光线传导至集尘盒140的侧壁后，由于集尘盒140的侧壁由透光材料成型，故指示光线能够将集尘盒140整体点亮，吸尘器100的指示效果更好。
进一步的，状态指示灯160为多个，且分别在满足对应的触发条件时发出指示光线，多个状态指示灯160具有不同颜色的指示光线。
也就是说，当出现不同的状况时，集尘盒140被点亮的颜色是不一样的。 譬如，当集尘盒140满载时，对应的状态指示160可发出红光；而当滤网120堵塞时，对应的状态指示160可发出蓝光。如此，用户只需根据集尘盒140的颜色便可知晓吸尘器100的状态，从而使得操作更方便。
螺旋导风件130设于排风通道内并位于滤网120进风侧及出风侧的至少一侧，流经排风通道的气流在螺旋导风件130的导流作用下形成旋转气流。螺旋导风件130上设有能够使气体朝预设方向改变流向的导向结构。气体流经螺旋导风件130时，通过对气体进行导流改变气流的方向，从而形成旋转气流。
吸尘器100工作时，夹带杂质的气流会依次由进风通道112、集尘腔朝滤网120流动。经螺旋导风件130导流后，流经排风通道的气流并非直吹向滤网120，而是带有旋转。因此，气流中的杂质也不会垂直撞向滤网120，而是具有横向的速度，故杂质对滤网120的冲击减弱不易附着于滤网120。而且，旋转气流还能形成扰动，从而将已经吸附于滤网120表面的杂质卷起，从而能够防止杂质在滤网120的表面一直堆积。由此可见，虽然吸尘器100工作时滤网120两侧存在压力差，但杂质依然不易在滤网120表面沉积，从而能有效地避免滤网120堵塞，保证吸尘器100的效率。
在本实施例中，进风通道112及排风通道与集尘腔的同一侧相连通，并与集尘腔配合形成U形腔体结构。
进风通道112及排风通道可以是长条形的通道，两者并列设置，且与集尘腔连通的开口朝向相同。即，进风通道112的开口不与排风通道的开口相对设置。当夹带杂质的气流经进风通道112进入集尘腔时，将首先撞击集尘腔的底部。然后，经过变向的气流才向排风通道流动。也就是说，由进风通道112流入的气流并不会直接吹向排风通道，而是在进入排风通道前经过了缓冲。因此，显著减小了杂质撞向滤网120时的冲击力，从而能够进一步的防止杂质在滤网 120的表面附着。
螺旋导风件130可位于滤网120的进风侧，也可位于滤网120的出风侧。如图3所示，具体在本实施例中，滤网120的进风侧及出风侧均设有螺旋导风件130。滤网120两侧的螺旋导风件130的结构可以相同。气流在穿过滤网120时，会经过螺旋导风件130两次导流，故其流向将会经过两次扭转。如此一来，所形成的旋转气流的转速将更快，从而能够在滤网120表面形成更大的扰动，卷起杂质的效果也更明显。
螺旋导风件130的具体结构有多种可能，只要能使得直吹向排风通道的气流通过后形成旋转气流即可。
请一并参阅图4，具体在本实施例中，螺旋导风件130包括环形的边框131及多个叶片132，每个叶片132由边框131的中心向边缘延伸，且多个叶片132呈放射状排列。
边框131的轮廓与排风通道的内侧轮廓相匹配，可以呈圆环或矩形环结构。边框131起支撑作用，可通过卡扣卡接的方式固定于排风通道。每个叶片132的表面均具有一定的斜度，故均能实现对气体的导流并使气体的流向产生偏转。
气流可从相邻两个叶片132之间的间隙通过螺旋导风件130，多个叶片132将气流分割为多股小股气流，且每股气流均可在叶片132的作用下形成旋转气流。如此，当气流通过螺旋导风件130后，将会形成多股旋转气流相互作用的情况，这对滤网120表面的扰动更明显，从而针对滤网120表面沉积的杂质的清理效果更佳，进一步降低滤网120堵塞的概率。
显然，在其他实施例中，螺旋导风件130也可为其他结构。譬如，在另一个实施例中，螺旋导风件130包括螺旋状的导风片(图未示)，导风片设于排风通道的内壁，并绕排风通道的轴线螺旋延伸。
螺旋状的导风片会使流经排风通道的气流沿螺旋路径流动，从而形成旋转气流。此时，气流整体旋转，并不会形成多股旋转气流。螺旋状的导风片可延伸至滤网120的两侧，也可仅分布于滤网20的一侧。
进一步的，在本实施例中，位于滤网120进风侧的螺旋导风件130与位于出风侧的螺旋导风件130同轴设置，且两侧的螺旋导风件130在边框131的周向上存在错位。
错位指的是，其中一侧的螺旋导风件130相对于另一侧的螺旋导风件130，相当于沿边框131的周向旋转预设角度。因此，两侧的螺旋导风件130上的叶片132并不是完全对齐。如此设置，当气流穿过两侧的螺旋导风件130时，所形成的旋转气流的转速越块，故扰动效果更好，能够进一步增强对滤网120的清洁作用。
进一步的，在本实施例中，螺旋导风件130还包括位于边框131的中部并与边框131同轴设置的通风环133，每个叶片132由通风环133的外壁向边框131的内壁延伸。
通风环133可以是圆环结构，与边框131的材质相同。气流流经螺旋导风件130时，部分气流直接由通风环133穿过而形成中心气流，另一部分气流则由叶片132之间的间隙通过，形成边缘气流。由于叶片132的阻挡，边缘气流的流速将小于中心气流的流速。根据伯努利原理，流速越大，压力越小。因此，边缘气流将会具有向中心气流靠拢的趋势。如此，可使气流转动更明显，从而进一步提升旋转气流对滤网120表面的扰动作用。
上述吸尘器100，启动工作时，夹带杂质的气流经进风口111、进风通道112进入集尘腔，气流中的杂质被滤网120阻隔从而留在集尘腔内，而剩余的尾气则经排风通道由排风口113排出。气流在经过螺旋导风件130时，将在螺旋导 风件130的作用下旋转气流。也就是说，流经排风通道的气流并非直吹向滤网120。因此，气流中的杂质也不会垂直撞向滤网120，而是具有横向的速度，故不易附着于滤网120。而且，旋转气流还能形成扰动，从而将吸附于滤网120表面的杂质卷起，能够进一步防止杂质在滤网120的表面堆积。因此，上述吸尘器100在工作时能有效地避免滤网120堵塞。
以上所述实施例的各技术特征可以进行任意的组合，为使描述简洁，未对上述实施例中的各个技术特征所有可能的组合都进行描述，然而，只要这些技术特征的组合不存在矛盾，都应当认为是本说明书记载的范围。
以上所述实施例仅表达了本实用新型的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对实用新型专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本实用新型构思的前提下，还可以做出若干变形和改进，这些都属于本实用新型的保护范围。因此，本实用新型专利的保护范围应以所附权利要求为准。
