Description

一种反向吹风及敲击式海帕自清洁吸尘器 技术领域
本发明涉及吸尘器领域，特别涉及一种反向吹风及敲击式海帕自清洁吸尘器。
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。
吸尘器在除污过程中，无论是尘款式过滤还是旋风式过滤，都会有灰尘附着在过滤海帕进风一侧的表面，使用时间越久，过滤海帕表面积累的灰尘越多，会逐渐减弱过滤海帕的透气性能，造成风力下降，从而降低吸尘器的除尘性能。
有鉴于此，实有必要开发一种反向吹风及敲击式海帕自清洁吸尘器，用以解决上述问题。

其中，进风仓162及所述过滤出风管均与所述电机容纳仓相连通。
再次参照图6，进风仓162的底部设有将其与外界相连通的左进风口1621与右进风口1622，左进风口1621与右进风口1622沿X轴方向直线布置，左进风口1621及右进风口1622分别与左抽风口1512及右抽风口1513相连通，左吹风口1514及右吹风口1515均与外界大气相连通。
参照图2，其特征在于，所述左抽风口切换机构包括：
设于安装板151上的左驱动器153；以及
滑动覆盖于左抽风口1512与左吹风口1514上的左切换板154，
其中，左切换板154设于左进风口1621与安装板151之间，左切换板154上开设有左透风口1541，左切换板154与左驱动器153传动连接使得左切换板154在左驱动器153的驱动下在Y轴方向上往复滑移，从而使得左透风口1541交替地与左抽风口1512及左吹风口1514相连通。
进一步地，所述右抽风口切换机构包括：
设于安装板151上的右驱动器152；以及

其中，右切换板155设于右进风口1622与安装板151之间，右切换板155上开设有右透风口1551，右切换板155与右驱动器152传动连接使得右切换板155在右驱动器152的驱动下在Y轴方向上往复滑移，从而使得右透风口1551交替地与右抽风口1513与右吹风口1515相连通。
参照图7级图8，敲击驱动器141的动力输出端传动地连接有拨轮142，拨轮142的侧面上设有至少一个往外侧凸起的拨动端1421，拨轮142在敲击驱动器141的驱动下周期性地在竖直平面内转动，使得其上的拨动端1421周期性地将敲击锤143向上拨动，拨轮142与敲击锤143相对应。

其中，敲击部1432与安装罩151的顶壁间弹性地设有回复弹簧144，敲击部1432在回复弹簧144的回复力作用下使得敲击部1432的底面与过滤海帕17的顶面持续接触，敲击部1432的外壁上与拨轮142相对侧形成有往外凸起的受力端1433，拨轮142在竖直平面内转动时，其上的拨动端1421周期性将受力端1433向上拨动，以使得敲击部1432的底面相对于过滤海帕17的顶面周期性地向上抬起一段距离。
在一实施方式中，敲击部1432的上表面开设有弹簧安装槽，回复弹簧144的底部设于所述弹簧安装槽中。
在一实施方式中，安装罩15的上表面形成有竖直下沉的驱动器安装室1511，敲击驱动器141设于该驱动器安装室1511中。
在优选的实施方式中，敲击锤143关于敲击驱动器141对称式地设有两组。
工作原理：
参照图2，此时左抽风口1512关闭、左吹风口1514打开，而右抽风口1513打开、右吹风口1515关闭，右进风口1622与右抽风口1513相连通，左进风口1612与左抽风口1512间被隔断，左吹风口1514与外界大气相连通，当左电机167及右电机168转动抽风时，进风仓162形成负压，集尘桶11内的空气经过滤海帕17的右半部过滤后，通过右抽风口1513进入到进风仓162内，并最终被排出外界大气，而由于集尘桶11在其内部空气被抽走的同时其内部也会形成负压，这就导致外界大气通过左吹风口1514进入到左进出仓，进而对过滤海帕17的左半部上表面进行吹拂，从而使得过滤海帕17的左半部下表面所堆积的灰尘被吹落至集尘桶11内，当吸尘器1在此工作状态工作一段时间后，左驱动器153及右驱动器152分别驱动左切换板154及右切换板155，使得左抽风口1512打开、左吹风口1514关闭，而右抽风口1513关闭、右吹风口1515打开，在此状态下的气流流动原理与上一状态相似，在此不再赘述，在气流对海帕进行反向吹风的同时，敲击驱动器141持续地驱动敲击锤143对过滤海帕17的上表面进行敲击，使得过滤海帕17上所积累的灰尘掉落得更为迅速、彻底，从而大大提高了灰尘的自清洁效果与效率。
