Description

自移动清洁设备、尘盒及清洁系统 技术领域
本申请涉及一种自移动清洁设备及清洁系统。
背景技术
相关技术中的自移动清洁设备，是智能家用电器的一种，应用广泛。自移动清洁设备的主要工作过程为：自移动清洁设备在地面上移动，将地面灰尘等垃圾吸纳进入自身的尘盒，从而完成地面清理的功能。为了减少用户需要经常清洁自移动清洁设备尘盒的烦恼，集尘充电座配置有吹风口，当自移动清洁设备与集尘充电座对接时，集尘充电座一边对尘盒吹风，扰动内部灰尘，一边吸尘盒中的灰尘，提升净空率，但是这样的装置的结构复杂，成本高。另外，在充电座上集成了中央集尘系统，可在自移动清洁设备充电时吸出尘盒中的灰尘，降低清洁扫地机尘盒的频率，但是，自移动清洁设备尘盒中的灰尘排出率并不高，仍需要用户不定时清洁，并且长期存在于死角的垃圾有霉变风险。中央集尘系统在吸出自移动清洁设备中的灰尘的一种工作方式为，从尘盒的排尘口吸尘时，尘盒的吸尘口关闭，气流从风机所在风道进入尘盒扰动灰尘从而将灰尘带走，但是此方式工作时风道中的风向与风机正常工作时刚好相反，且真空远大于风机正常工作状态，对设置在风道处的过滤系统具有产生损伤的风险。

此外，下面所描述的本申请不同实施方式中所涉及的技术特征只要彼此之间未构成冲突就可以相互结合。
本申请一实施例所示的清洁系统，包括自移动清洁设备、以及与自移动清洁设备对接的维护站(未图示)，维护站内设置有用以储存灰尘的存储空间，维护站具有与排尘口对接以连通存储空间和尘盒的吸入口。维护站内还设置有第二风机以实现与自移动清洁设备对接后使尘盒内的灰尘吸入至存储空间内并且被储存于存储空间内，因此，维护站的存储空间比自移动清洁设备的尘盒大。其中灰尘可以指(污物)灰尘、尘埃、粉末、污渍和其他灰尘颗粒，但不仅限于此，在此不再一一赘述。自移动清洁设备可在各种情形下与维护站对接，例如，自移动清洁设备的电池需要充电的情形下、自移动清洁设备完成清洁的情形下、自移动清洁设备内充满灰尘的情形下、或用户直接将自移动清洁设备放在维护站上的情形下等等。
维护站还设置有平台，以在自移动清洁设备与维护站对接时支撑自移动清洁设备。平台以倾斜的方式 设置，以使自移动清洁设备容易地爬上平台和从平台上爬下。用以引导自移动清洁设备的引导件形成于平台上，引导件为具有螺纹的结构，以此防止在平台上的自移动清洁设备从平台上滑下。维护站还包括设置在平台上充电装置，充电装置设置有多个连接端子用以与自移动清洁设备对接且给自移动清洁设备充电。
请参见图1至图3，本申请一实施例所示的自移动清洁设备1，包括壳体11、设置在壳体11内且用以存储灰尘的尘盒12、设置在壳体11内的风机13、以及设置在尘盒12内的扰流筋板14。壳体11具有吸尘口111、出风口112和排尘口113，排尘口113用以与维护站对接，灰尘经吸尘口111进入至尘盒12内。其中，吸尘口111、尘盒12、及出风口112形成吸尘风道，吸尘口111和/或出风口112、尘盒12、以及排尘口113形成排尘风道，具体的，排尘风道可以由吸尘口111、尘盒12、以及排尘口113形成，也可以由出风口112、尘盒12、以及排尘口113形成，还可以为吸尘口111和出风口112、尘盒12、以及排尘口113形成。自移动清洁设备1吸尘时，吸尘风道内通过风机13形成吸尘气流，吸尘气流用以将外部的灰尘从吸尘口111引入到尘盒12内，吸尘气流依次流经吸尘口111、尘盒12和出风口112；排尘口113与维护站对接进行排尘时，排尘风道内形成用以将尘盒12内的灰尘排入到维护站的存储空间内的排尘气流，排尘气流经吸尘口111和/或出风口112进入至尘盒12内经扰流筋板14分散并由排尘口113流出。
壳体11围设成自移动清洁设备1的主体形状，自移动清洁设备1可以形成为各种形状，本实施例中，自移动清洁设备1为圆形，呈圆形的壳体11被构造成具有固定的旋转半径，因此即使在旋转的情况下也能够避免与周围障碍物接触，并且容易改变方向。诚然，自移动清洁设备1的也可以为方形等结构，在此不做限制，可根据实际需要进行选择。吸尘口111和排尘口113设置在壳体11底部，出风口112设置在壳体11侧壁，吸尘口111处设置有滚刷15，滚刷15可旋转地安装在吸尘口111处，并且能够通过转动将地面上的灰尘拾取到尘盒12内。
自移动清洁设备1还包括驱动装置、各种传感器(未图示)和控制装置(未图示)。其中，驱动装置包括为使自移动清洁设备1在清洁区域上行驶而构造的左侧驱动轮161和右侧驱动轮162以及脚轮163。左侧驱动轮161和右侧驱动轮162被安装在壳体11的底部中央且相对设置在吸尘口111的两端，脚轮163被安装为壳体11的底部的靠近边缘的前侧，左侧驱动轮161、右侧驱动轮162和脚轮163三者呈三角形分布以使自移动清洁设备1具有稳定的姿态。
请结合图4至图6，尘盒12设置在壳体11的内部，本实施例中，尘盒12为类似长方体结构，但是尘盒12的结构可以为长方体、圆柱体、正方体中的一个，但是不仅限于此，也可以为其他结构，在此不一一列举。诚然，在其他实施例中，用以储存灰尘的结构也不仅限于尘盒，也可以是尘袋等结构，在此不做具体限制。尘盒12上设置有第一开口121、第二开口122、以及第三开口123。第一开口121设置在尘盒12侧壁上且靠近吸尘口111设置，使得从吸尘口111处进入的灰尘通过第一开口121进入到尘盒12。本实施例中，为了自移动清洁设备1与维护站对接后，使存储在尘盒12内的灰尘能够轻松的转移到维护站内，设置在壳体11的用以排出灰尘排尘口113与尘盒12上的第二开口122联通设置，这样设置，缩短灰尘的 传输通道，提高了灰尘传输效率，诚然，在其他实施例中，排尘口113与第二开口122也可以为同一个。尘盒12的第三开口123相对第一开口121设置且第三开口123靠近出风口112，靠近出风口112处设置有过滤组件17，本实施例中，过滤组件17设置在第三开口123处，过滤组件17可以为过滤网17，但不仅限于此，还可以为其他的可用以过滤气流的装置或部件，过滤网17为HEPA过滤网17，但同样不仅限于此，还可以为其他的过滤网。过滤组件17也可以设在其他位置处，在此不做具体限制。在此不对尘盒12的第一开口121、第二开口122、以及第三开口123的位置做具体的限制，可根据需要进行设置。
风机13包括风扇(未图示)和驱动风扇转动的电机(未图示)，风机13的结构可以采用相关技术中的结构，在此不做具体描述，风机13的设置尘盒12外侧，具体的，风机13设置在第三开口123和出风口112之间。因风机13的尺寸比较大，为了减小自移动清洁设备1的尺寸，将风机13倾斜设置其朝向尘盒12倾斜，风机13的倾斜的具体角度在此不做具体限制，可根据实际需要进行设置，容易想到是，风机13也可以不倾斜设置。
吸尘风道内设置有用以将吸尘风道关闭或打开的第一单向阀18，本实施例中，排尘风道由吸尘口111、尘盒12和排尘口113形成时，第一单向阀18设置在出风口112处，具体的，第一单向阀18设置在风机13与出风口112之间且靠近出风口112处。诚然，在其他实施例中，第一单向阀18也可以设置在尘盒12的第一开口121处或第三开口123处，第一单向阀的具体位置在此不做具体限制，可根据实际需要进行选择。当风机13启动工作时，形成从吸尘口111流向出风口112的吸尘气流时，第一单向阀18开启。反之，当自移动清洁设备1与维护站对接时，此时风机13停止工作，维护站的第二风机启动，此时第一单向阀18关闭，排尘风道只能由吸尘口111、尘盒12和排尘口113形成。诚然，在其他实施例中，第一单向阀设置在尘盒的第一开口处，当自移动清洁设备与维护站对接时，排尘风道只能由出风口、尘盒和排尘口形成；第一单向阀设置在尘盒的第三开口处，当自移动清洁设备与维护站对接时，排尘风道则由吸尘口、尘盒和排尘口形成；如果吸尘风道内没有设置第一单向阀，则当自移动清洁设备与维护站对接时，排尘风道则由两个通道，一个是由吸尘口、尘盒和排尘口形成，另一个由出风口、尘盒和排尘口形成。
排尘口113处设置有将排尘风道打开或关闭的第二单向阀19，当风机13启动工作时，形成从吸尘口111流向出风口112的吸尘气流时，第二单向阀19关闭，无法从排尘口113处进风。反之，当自移动清洁设备1与维护站对接时，此时风机13停止工作，维护站的第二风机启动，此时第二单向阀19开启，第一单向阀18和第二单向阀19的工作状态相反。
扰流筋板14朝向吸尘口111或出风口112设置，请参见图7，扰流筋板14为长方体结构，在扰流筋板14的其中一面上设置有两个弯曲形状的扰流筋141，两个扰流筋141相对设置，扰流筋板14用以将流向其设置有扰流筋141的一面的气流分散，使得气流的分布范围变大，在此，对扰流筋板14的大小、形状、扰流筋141设置的数量、扰流筋141所在的具体位置和形状不做具体限制。本实施例中，扰流筋板14 靠近尘盒12的第一开口121设置，同时具有扰流筋141的一面朝向第一开口121，以此实现当气流从第一开口121流向扰流筋板14时，气流被扰流筋板14扰流分散。
在一种可能的实现方式中，扰流筋板14朝向尘盒内部的一面设置有至少一组扰流筋141，其中每组扰流筋141包括相对设置的两个弯曲形状的扰流筋141。具体地，每组扰流筋141中的两个扰流筋141可以设置成将气流分散的结构。
在一种可能的实现方式中，每组扰流筋141中的两个扰流筋141靠近所述吸尘口/第一开口的一端形成的通道1411小于两个扰流筋远离吸尘口/第一开口的一端形成的通道1412。
本实施例中，自移动清洁设备1的清扫灰尘的工作原理为：请结合图8，自移动清洁设备1移动到所需位置处，风机13启动工作，此时第一单向阀18开启，第二单向阀19关闭，在自移动清洁设备1内形成吸尘气流，吸尘气流依次流经吸尘口111、第一开口121并进入尘盒12、第三开口123并流出尘盒12和出风口112，以此将位于相应位置处的灰尘被吸入吸尘口111，气流带动灰尘在吸尘风道内移动，因第三开口123处设置有过滤组件17，灰尘被阻挡而存于尘盒12内，被过滤后的气流流向出风口112而排出自移动清洁设备1，此时设置在吸尘口111处的滚刷15转动，帮助灰尘的吸入，提高清洁效率。
自移动清洁设备1与维护站对接，排出尘盒12内的灰尘的工作原理为：请结合图9，排尘口113与吸入口对接，位于维护站内的第二风机启动工作，此时第一单向阀18关闭，第二单向阀19开启，在自移动清洁设备1和维护站之间形成排尘气流，排尘气流流经吸尘口111、第一开口121并进入尘盒12、第二开口122并流出尘盒12、吸入口并进入维护站，因第一开口121处设置有扰流筋板14，气流被分散并流向尘盒12其他位置，以此位于尘盒12内的灰尘被气流吹动并随着气流排出尘盒12，有效带动尘盒12内的灰尘顺利从排尘口113排出，提高了尘盒12的排尘净空率和死角清洁能力。此外，本实施例中，因第一单向阀18的存在，有效避免气流从出风口112流入并通过位于第三开口123处的过滤组件17，避免了过滤组件17因气流风向的转变而存在损坏的可能，保证的过滤组件17是使用寿命，同时，气流只从吸尘口111进入，增大尘盒12内的气流流速。需要说明的是，当第一单向阀18设置在尘盒12的第一开口121处时，排尘气流则流经出风口112、第二开口122并进入尘盒12、第二开口122并流出尘盒12、吸入口并进入维护站。当第一单向阀18设置在尘盒12的第三开口123处，此时排尘气流则流经吸尘口111、第一开口121并进入尘盒12、第二开口122并流出尘盒12、吸入口并进入维护站。
综上，由于自移动清洁设备的尘盒内设置扰流筋板，在清洁尘盒时，气流被分散并流向尘盒其他位置，增大尘盒腔体内的气体和范围，能够有效带动尘盒内的灰尘顺利从排尘口排出，从而提升自移动清洁设备的排尘净空率、灰尘排出率、以及死角清洁能力。
以上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。
以上实施例仅表达了本申请的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干变形和改进，这些都属于本申请的保护范围。因此，本申请专利的保护范围应以所附权利要求为准。
