Description

一种用于海帕自清洁式吸尘器的电机底座 技术领域
本发明涉及吸尘器领域，特别涉及一种用于海帕自清洁式吸尘器的电机底座。
背景技术
吸尘器的工作原理是，利用电动机带动叶片高速旋转，在密封的壳体内产生空气负压，吸取带有尘屑的地毯、地板、墙体等物体表面，而尘屑随着空气被一同吸入尘气分离组件中后，尘屑被尘气分离组件中的海帕所过滤并被集尘桶所收集，过滤后的洁净空气则被排除吸尘器机体外。
海帕在工作一段时间后，其位于集尘桶一侧的表面上吸附有大量尘屑，尘屑大量附着在海帕表面会将海帕表面的微小过滤筛孔堵塞，进而影响海帕的过滤能力，目前市场上的吸尘器产品存在以下几个问题：一方面，现有的吸尘器缺少对海帕进行自清洁的功能，一般发生海帕堵塞问题后，要么拆机后对海帕进行拍打除屑，要么拆机后直接对海帕进行换新，无论哪种方式都将花费大量清理时间，而后者将直接导致耗材的替换成本；另一方面，现有的吸尘器即使设有海帕自清洁功能，也是采用的电磁继电器结构，即采用机械式敲打海帕，使得海帕表面的尘屑抖落至集尘桶中，这种除屑方式使得海帕表面的尘屑清理得不彻底，产品结构较复杂，且使用成本较高。
为此，我司开发了一种自清洁式吸尘器，其采用两个风道及两个电机，将海帕一分为二，两个电机同时工作，使得一半的海帕在正向抽风过滤尘屑时，另一半的海帕则进行反向吹风除尘，这就需要用到用于安装电机并对气流进行导向的电机底座，而现有的电机底座，一方面体积臃肿、结构复杂，另一方面，风道的集成与导向复杂，使得风道在切换过程中风能损耗过大，导致噪音大、风力小等问题。
有鉴于此，实有必要开发一种用于海帕自清洁式吸尘器的电机底座，用以解决上述问题。

优选的是，右导流风道在其风道末端处的口径尺寸小于前壁板与后壁板之间的间距，以使得右挡风板向右导流风道内部转动的趋势被右导流风道所限制。

参照图7及图8，左导流风道1312在其风道末端处的口径尺寸小于前壁板1351与后壁板1352之间的间距，以使得左挡风板181向左导流风道1312内部转动的趋势被左导流风道1312所限制。
进一步地，右导流风道1322在其风道末端处的口径尺寸小于前壁板1351与后壁板1352之间的间距，以使得右挡风板182向右导流风道1322内部转动的趋势被右导流风道1322所限制。
参照图2及图3，左电机容纳室131与右电机容纳室132的正下方分别间隔地设有左抽气室133及右抽气室136，其中，左抽气室133与右抽气室136相连通，左抽气室133及右抽气室136与气流汇流室134均间隔设置。
进一步地，左电机容纳室131的底壁及右电机容纳室132的底壁分别设有通往左抽气室133及右抽气室136的左通气孔1311a及右通气孔1321a。
进一步地，左抽气室133的底壁及右抽气室136的底壁上分别开设有连通外界的左抽气孔1331及右抽气孔1361，气流汇流室134的底壁上开设有连通外界的左吹气孔1341及右吹气孔1342。
再次参照图2及图3，左抽气孔1331的下开口及右抽气孔1361的下开口出分别设有左密封唇1331a及右密封唇1361a，其中，左密封唇1331a在左抽气孔1331的边缘处一体式地结合该左抽气孔1331并且沿左抽气孔1331的边缘处竖直向下延伸，右密封唇1361a在右抽气孔1361的边缘处一体式地结合该右抽气孔1361并且沿右抽气孔1361的边缘处竖直向下延伸。
这里说明的设备数量和处理规模是用来简化本发明的说明的。对本发明的应用、修改和变化对本领域的技术人员来说是显而易见的。
工作原理：
参照图7，左导流风道1312中的气流沿箭头A方向流动，右导流风道1322中的气流沿箭头B方向流动，左挡风板181及右挡风板182在未受到气流推动作用时，均呈自由下垂之势，参照图3，左导流风道1312的风道末端分别设有左前限位板1354及左后限位板1356，左挡风板181在自然下垂时，其向左旋转的趋势被左前限位板1354及左后限位板1356所限制；右导流风道1322的风道末端分别设有右前限位板1355及右后限位板1357，右挡风板182在自然下垂时，其向右旋转的趋势被右前限位板1355及右后限位板1357所限制。
以右导流风道1322与汇流口1353相连通为例来进一步阐述。参照图8，左导流风道1312中的气流流量远远小于右导流风道1322中的气流流量，进而使得右挡风板182受到右导流风道1322中持续气流的影响而向左旋转直至打平，而左挡风板181受到右导流风道1322中持续气流的影响而向左旋转至竖直下垂状态并将左导流风道1312进行封堵，气流通过汇流口1353导入到气流汇流室134中。左导流风道1312与汇流口1353相连通的原理与上述类似，在此不再赘述。
尽管本发明的实施方案已公开如上，但其并不仅限于说明书和实施方式中所列运用，它完全可以被适用于各种适合本发明的领域，对于熟悉本领域的人员而言，可容易地实现另外的修改，因此在不背离权利要求及等同范围所限定的一般概念下，本发明并不限于特定的细节和这里示出与描述的图例。
