Description

垃圾箱及扫地机器人 技术领域
本申请属于清洁设备技术领域，更具体地说，是涉及一种垃圾箱及扫地机器人。
 背景技术
环境卫生是影响生活质量的重要因素，因此，伴随着人们对生活质量要求的不断提高，相应地对环境卫生的要求也越来越高，然而现代人们的工作压力与日剧增，急需从繁重的清洁工作中解放出来，于是出现了许多帮助人们清洁地面的设备，常用的有吸尘器、自动拖布机、扫地机器人以及洗地机器人等。
目前，市场上的扫地机器人一般都是采用微小孔隙过滤法，即利用海绵、筛网等材料的微小孔隙阻挡住较大体积的灰尘颗粒，使这些灰尘颗粒不容易进入到除尘机构的高效过滤网里。但是采用微小孔隙过滤法有诸多缺点，如果孔隙过小，灰尘颗粒容易堵塞孔隙，降低了扫地机器人的吸力，影响了吸尘效果；如果孔隙过大，则起不到过滤的作用，导致更多的灰尘颗粒进入到高效过滤网里，缩短了高效过滤网的寿命。

请参阅图1至图4，现对本申请提供的垃圾箱进行说明。该用于扫地机器人1上的垃圾箱20包括箱体21、灰尘分离单元22、第一过滤网23以及第二过滤网24，其中，箱体21的内部开设有第一空腔213、第二空腔214和第三空腔215，该第一空腔213与箱体的进风口211连通，用于收集垃圾，该第二空腔214与第一空腔213和第三空腔215连通，用于分离灰尘，该第三空腔215与箱体的出风口212连通，并且第一空腔213、第二空腔214和第三空腔215沿气流前进的方向依次排列；灰尘分离单元22设置在第二空腔214内，用于分离被气流带入第二空腔214内的灰尘；第一过滤网23设置在第一空腔213和第二空腔214之间，可以阻隔第一空腔213与第二空腔214连通，使得从第一空腔213流向第二空腔214的气流必须经过第一过滤网23，第一过滤网23即为初效过滤网，用于止挡垃圾致使垃圾滞留在第一空腔213内；第二过滤网24设置在第三空腔215内，可以阻隔第二空腔214与箱体的出风口212连通，使得从第二空腔214流向箱体的出风口212的气流必须经过第二过滤网24，第二过滤网24即为高效过滤网，用于过滤从灰尘分离单元22逃逸的灰尘。
可以理解的是，在本申请实施例中，垃圾箱20需跟抽风装置配合，使空气产生从箱体的进风口211流入经箱体的出风口212流出的气流；垃圾是指毛发、纸片、体积较大的灰尘颗粒等，灰尘是指体积较小的能够穿过第一过滤网23的灰尘颗粒、碎屑等；箱体21可以被打开，有利于用户对第一空腔213、第二空腔214和第三空腔215进行清理，以及对第一过滤网23和第二过滤网24进行更换。
优选地，第二空腔214位于第一空腔213和第三空腔215的后侧，第三空腔215位于第一空腔213的顶侧，这样可以使箱体21的内部结构更加紧凑，有利于垃圾箱20的小型化设计。
本申请提供的垃圾箱20，采用了灰尘分离单元22，通过灰尘分离单元22将气流中能够穿过第一过滤网23的灰尘分离出来，降低第一过滤网23的孔隙尺寸设计的限制，保证与垃圾箱20配合的抽风装置的吸力，进一步减少进入第二过滤网24内的气流中夹带的灰尘量，延缓第二过滤网24堵塞的频率，从而有效地解决了扫地机器人无法兼顾吸力和高效过滤网使用寿命的技术问题，在保证足够吸力的前提下，降低了用户清理高效过滤网的频率，延长了高效过滤网的寿命，提升了用户的使用体验效果。
进一步地，请参阅图2至图4，作为本申请提供的垃圾箱的一种具体实施方式，第二空腔214包括安装腔2141和集尘腔2142，该安装腔2141通过连接孔与集尘腔2142连通，同时，灰尘分离单元22包括旋风筒221和盖体222，其中，旋风筒221封盖在该连接孔处，用于使进入旋风筒221内部的气流发生旋转，并且旋风筒的排尘口2213伸入集尘腔2142内；盖体222封盖在旋风筒的出风口2212处，用于将安装腔2141分隔为进风腔2141a和出风腔2141b，该进风腔2141a与旋风筒的进风口2211和第一过滤网23连通，该出风腔2141b与第三空腔215连通。具体地，旋风筒221包括上部和下部，旋风筒221上部的外轮廓呈柱状，旋风筒221下部的外轮廓呈倒圆台状，旋风筒的进风口2211开设在旋风筒221上部的侧壁上，并且与进风腔2141a连通，旋风筒的出风口2212开设在旋风筒221上部的顶壁上，旋风筒的排尘口2213开设在旋风筒221下部的底壁上，并且容置在集尘腔2142内，盖体222封盖在旋风筒的出风口2212处，并且在盖体222上凸设有中空管2220，中空管2220的一端与出风腔2141b连通，中空管2220的另一端向旋风筒的排尘口2213所在侧延伸，旋风筒221通过中空管2220与出风腔2141b连通，即中空管2220的内孔贯穿盖体222，并且中空管2220延伸的长度大于旋风筒的进风口2211的宽度，此处，旋风筒的进风口2211的宽度是指沿旋风筒221的中轴线延伸方向测量的宽度，优选地，中空管2220穿过旋风筒221的上部并且伸入旋风筒221的下部中，中空管2220的底端与旋风筒的排尘口2213之间具有间隙。这样当气流从旋风筒的进风口2211进入旋风筒221内后，气流会沿着旋风筒221的内壁绕中空管2220旋转形成旋风，并且自上而下沿螺旋状路径流动，最终经过中空管2220流出旋风筒221，此时，在气流旋转的过程中，由于离心力的作用，气流中夹带的灰尘会被甩出气流外，接着被甩出的灰尘会沿着旋风筒221的内壁，从旋风筒的排尘口2213在重力作用下自由落入集尘腔2142内，从而完成灰尘的分离，使得将要进入第二过滤网24的气流更加清净，进而延长了第二过滤网24的使用寿命，降低了用户清理第二过滤网24的频率，提升了用户的使用体验效果。
优选地，请参阅图2和图3，作为本申请提供的垃圾箱的一种具体实施方式，中空管2220与旋风筒221同轴，即中空管2220的中轴线与旋风筒221的中轴线在同一直线上。这样保证进入旋风筒221的气流旋转产生的离心力在各个方向上的强弱一致，提高了气旋除尘的效果。
进一步地，请参阅图3和图4，作为本申请提供的垃圾箱的一种具体实施方式，灰尘分离单元22包括至少两个旋风筒221，同时，在盖体222上凸设有至少两根中空管2220，此处，旋风筒221与中空管2220一一对应，即灰尘分离单元22包括一个盖体222和至少两个旋风筒221，每个旋风筒221与盖体222上的一根中空管2220配合，使进入旋风筒221内的气流旋转形成旋风。这样有效地提升了灰尘分离单元22的除尘效能。
进一步地，请参阅图3，作为本申请提供的垃圾箱的一种具体实施方式，集尘腔2142包括至少两个集尘分腔21420，至少两个集尘分腔21420相互隔断，即集尘分腔21420是一个个相互独立的腔体，此处，集尘分腔21420与旋风筒221一一对应。这样每个旋风筒221与每个集尘分腔21420可以组合形成单独的封闭空间，有效地避免相邻的两个旋风筒221之间发生气旋干扰，从而提升了灰尘分离单元22的除尘效能。当然，根据具体情况和需求，在本申请的其它实施例中，至少两个集尘分腔21420还可以相互连通，此处不作唯一限定。
优选地，请参阅图4和图5，作为本申请提供的垃圾箱的一种具体实施方式，灰尘分离单元22包括六个旋风筒221，它们分别为第一旋风筒221a、第二旋风筒221b、第三旋风筒221c、第四旋风筒221d、第五旋风筒221e以及第六旋风筒221f，并且第一旋风筒221a、第二旋风筒221b、第三旋风筒221c、第四旋风筒221d、第五旋风筒221e和第六旋风筒221f沿直线、圆弧线或者曲线依次排列。其中，第二旋风筒221b与第一旋风筒221a和第三旋风筒221c间隔分布，第五旋风筒221e与第四旋风筒221d和第六旋风筒221f间隔分布，并且第一旋风筒的进风口2211a和第二旋风筒的进风口2211b分别朝向第一旋风筒221a和第二旋风筒221b之间的间隔处，第三旋风筒的进风口2211c朝向第二旋风筒221b和第三旋风筒221c之间的间隔处，第四旋风筒的进风口2211d朝向第四旋风筒221d和第五旋风筒221e之间的间隔处，第五旋风筒的进风口2211e和第六旋风筒的进风口2211f分别朝向第五旋风筒221e和第六旋风筒221f之间的间隔处。具体地，在盖体222上凸设有六根中空管2220，集尘腔2142包括六个集尘分腔21420，它们分别与第一旋风筒221a、第二旋风筒221b、第三旋风筒221c、第四旋风筒221d、第五旋风筒221e和第六旋风筒221f一一对应配合，即灰尘分离单元22具有六个独立的除尘结构，进而提升了灰尘分离单元22的除尘效能；由于进入进风腔2141a的气流会集中地从第一旋风筒221a和第二旋风筒221b之间的间隔处、第二旋风筒221b和第三旋风筒221c之间的间隔处、第四旋风筒221d和第五旋风筒221e之间的间隔处以及第五旋风筒221e和第六旋风筒221f之间的间隔处通过，六个旋风筒的进风口朝向不同的间隔处有利于平衡进入六个旋风筒的风量，如此可以有效保证充分发挥六个旋风筒的除尘效能，提升了灰尘分离单元22的除尘效果。
进一步地，请参阅图4和图5，作为本申请提供的垃圾箱的一种具体实施方式，第一旋风筒的进风口2211a和第六旋风筒的进风口2211f同侧分布，第二旋风筒的进风口2211b、第三旋风筒的进风口2211c、第四旋风筒的进风口2211d和第五旋风筒的进风口2211e同侧分布。具体地，当气流从箱体的进风口211进入第一空腔213后再流入第二空腔214内时，由于惯性的作用，位于中间位置的旋风筒221会得到更大的气流量，为了平衡六个旋风筒221的气流量，此处将第二旋风筒的进风口2211b、第三旋风筒的进风口2211c、第四旋风筒的进风口2211d和第五旋风筒的进风口2211e布置在靠近箱体21后壁的一侧，并且将第一旋风筒的进风口2211a和第六旋风筒的进风口2211f布置在靠近第一空腔213的一侧。这样的排布方式使得六个旋风筒221的进风口更加适配气流的流向，有利于气流进入六个旋风筒内，进而充分发挥六个旋风筒的除尘效能，提升了灰尘分离单元22的除尘效果。
请参阅图6，本申请还提供了一种扫地机器人1，包括主机10和垃圾箱20，其中，垃圾箱20可拆卸地连接在主机10的后侧。
本申请提供的扫地机器人1，采用了垃圾箱20，通过灰尘分离单元22将气流中能够穿过第一过滤网23的灰尘分离出来，降低第一过滤网23的孔隙尺寸设计的限制，保证与垃圾箱20配合的抽风装置的吸力，进一步减少进入第二过滤网24内的气流中夹带的灰尘量，延缓第二过滤网24堵塞的频率，从而有效地解决了扫地机器人无法兼顾吸力和高效过滤网使用寿命的技术问题，在保证足够吸力的前提下，降低了用户清理高效过滤网的频率，延长了高效过滤网的寿命，提升了用户的使用体验效果。
进一步地，作为本申请提供的扫地机器人的一种具体实施方式，在主机10内设置有抽风机（未图示），该抽风机的进风口与箱体的出风口212相接。具体地，在主机10的内部开设有抽风通道，该抽风通道的一端与抽风机的进风口密封连接，该抽风通道的另一端与箱体的出风口212密封连接，当抽风机启动后，使夹带垃圾和灰尘的气流依次通过箱体的进风口211、第一空腔213、第一过滤网23、第二空腔214、灰尘分离单元22、第三空腔215和第二过滤网24后，被净化成洁净的气流从箱体的出风口212流出。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
