Description

一种用于海帕自清洁式吸尘器的风道快速切换装置 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风道快速切换装置。
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，这就需要用到风道快速切换装置，以用于将两个电机产生的负压及气流进行导向及交替切换，使得两半海帕能够交替地进行除尘及过滤，而现有的风道快速切换装置存在以下几个问题：首先，体积臃肿、结构复杂；再次，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；最后，风道的来回往复切换存在滞后性，导致实际使用过程中出现响应慢、操作灵敏度低，降低了操作者的使用体验。
有鉴于此，实有必要开发一种用于海帕自清洁式吸尘器的风道快速切换装置，用以解决上述问题。
发明内容
针对现有技术中存在的不足之处，本发明的目的是提供一种用于海帕自清洁式吸尘器的风道快速切换装置，其在提高结构紧凑性、降低结构体积及复杂度的同时，还通过对两个风道进行优化设计来降低风道切换过程中的风能损耗及吸尘器的工作噪声，同时提高了风道切换的响应速度，进而提高了对海帕清洁效率及海帕的使用寿命，具有广阔的市场应用前景。

工作原理：
参照图3及图4，通常海帕设置于电机底座13的正下方，以左抽气孔1331及右吹气孔1342被封闭时，左吹气孔1341及右抽气孔1361开启为例进行阐述说明，此时，左电机161及右电机162均通过右抽气孔1361中将右电机容纳室132正下方空气抽取，左导流风道1312及右导流风道1322中均产生过滤后的洁净气流，尘屑则被右电机容纳室132正下方的海帕所过滤，由于左电机161从右抽气孔1361中抽取空气的路径远远长于右电机162从右抽气孔1361中抽取空气的路径，从而使得左导流风道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，由于气流汇流室134中的右吹气孔1342被封闭，左吹气孔1341开启，则汇流后的气流经左吹气孔1341导向后，吹向左电机容纳室131正下方的海帕上表面，从而将吸附于海帕下表面的尘屑吹落去除……如此工作一段时间后，左切换电机171及右切换电机175动作，使得左抽气孔1331及右吹气孔1342开启，而左吹气孔1341及右抽气孔1361被封闭，此后空气的流通顺序与上述相似，在此不再赘述……如此循环往复，直至吸尘器完成清扫作业。
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。
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。
