Description

一种吸尘器的伸缩折叠桶 技术领域
本发明属于吸尘设备领域，具体涉及一种吸尘器的伸缩折叠桶。
背景技术
桶式吸尘器，其主要是由抽吸的头部和下部分的集尘桶组成，其工作原理是，利用电动机带动叶片高速旋转，在集尘桶内产生空气负压，吸取尘屑。
目前，现有的桶式吸尘器往往是大中型公共场合常用的清洁设备，因此，其主要特点是容量大、能吸水，但是由于其追求容量大的特点，这类桶式吸尘器的集尘桶都做的很大，一般的集尘桶包括内桶、外桶、及设置在所述内桶和所述外桶之间的密封件，因此，由于内外桶之间不可活动，一方面负压空腔容量大小无法根据实际使用需要进行改变，造成吸附能力和效率低；另一方面，因体积过大，存储不便，占用空间大，不利于运输。
发明内容
本发明所要解决的技术问题是克服现有技术的不足，提供一种改进的吸尘器的伸缩折叠桶。
为解决上述技术问题，本发明采取的技术方案如下：
一种吸尘器的伸缩折叠桶，其包括内桶、外桶、及密封件，其中内桶的内腔与外桶的内腔相贯通并形成吸尘腔，内桶和外桶相对活动的密封连接，且吸尘腔随着内桶和外桶相对展开或折叠对应进行变大或变小调节；伸缩折叠桶还包括将内桶和外桶相对锁定的锁定件。
优选地，内桶上下活动在外桶上，其中内桶向上运动时，内桶和外桶处于展开状态，吸尘腔变大，内桶向下运动时，内桶和外桶处于折叠状态，吸尘腔变小。这样一来，在上下相对运动中，不仅能够改善吸尘腔的容积大小，而且伸缩折叠后桶的体积小，存储方便，占用空间小，利于运输(包装运输装箱量可实现最大化)。
根据本发明的一个具体实施和优选方面，密封件包括设置在内桶和外桶之间的密封条，其中密封条绕着内桶的周向设置，且固定在内桶上或所述外桶上。这样一来，随着内桶相对外桶上下活动时，保证吸尘腔保持封闭状态。
优选地，密封条固定在内桶的底部。通过密封条分布，不仅保证任意位置的内外桶之间密封，而且能够呈现最大化的吸尘腔容积。
根据本发明的又一个具体实施和优选方面，在外桶内形成有绕外桶内壁周向设置的内衬，其中内衬的内腔与内桶的内腔构成吸尘腔，在内桶和外桶上下运动中，内衬与内桶保持密封设置。在内衬的设置下，不仅便于密封件的设置，而且提高内外桶相对运动的密封性。
优选地，内衬自底面密封贴合在外桶的桶底壁上，内桶位于内衬和外桶之间，密封件将内桶和内衬之间相对密封，或者密封件将外桶、内桶、及内衬三者之间相密封。在此，由密封件的所形成的多重密封，更有利于实施吸尘腔容积的改变。
进一步的，内衬顶部形成有绕内衬顶部周向设置的限位边，其中在内桶和外桶处于展开极限状态时，密封条贴合在内衬的顶部且抵触在限位边的底部；当内桶和外桶处于完全折叠时，密封条贴合在内衬的底部且抵触在外桶底部的内壁。这样设置，当吸尘腔容积最大时，能够使得内外桶和内衬之间更加稳定的处于相对锁定状态。
根据本发明的又一个具体实施和优选方面，锁定件包括设置在外桶上的第一锁合部、设置在内桶上的第二锁合部，其中由第一锁合部和第二锁合部的配合，将内桶和外桶锁定在折叠状态或展开状态。直接通过内外桶上的锁合部的配合，将内桶和外桶相对锁定，操作简单，实施方便。
具体的，第一锁合部和第二锁合部中的一个为锁孔，另一个为与锁孔相配合的锁舌，其中沿着上下方向并排形成多个锁孔，多个锁孔中位于顶部和底部分别为上锁孔和下锁孔，位于上锁孔和下锁孔之间的为中部锁孔，在完全折叠状态时，锁舌伸入下锁孔并配合锁定；在展开极限状态时，锁舌伸入上锁孔并配合锁定。这样一来，根据锁孔不同位置的分布，实现内外桶在上下活动中对应位置的锁定。
优选地，第一锁合部为锁孔且位于外桶的内壁，第二锁合部包括锁舌且设置在内桶的外壁。
进一步的，锁定件还包括驱动锁舌运动或复位的动力器。这样一来，可以通过动力器对锁舌的驱动，实现锁合和锁孔的锁合与解锁。
根据本发明的又一个具体实施和优选方面，锁定件有两组，且对应设置在伸缩折叠桶的相对两侧，其中两个锁舌能够同步伸入或退出相对应的上锁孔或下锁孔。这样一来，提高内外桶上下活动调节的平稳性，进而降低相对活动的 密封要求。
此外，在内桶的顶部形成连接边，伸缩折叠桶还包括连接在连接边上的桶盖，吸尘器的机头安装在桶盖上且下部伸入吸尘腔。使得结构更加紧凑，而且体积小，便于存储和运输。
优选地，吸尘器的机头能够上下活动且密封的安装在桶盖上。进一步的减少机头占用吸尘腔的空间，以增大吸尘腔容积。
优选地，外桶包括外桶底板、外桶壁板，其中外桶壁板自外桶底板的侧边倾斜向上延伸，且形成外桶的内腔自上而下逐步变小；内桶包括多个围成所述内桶内腔的内桶壁板，其中内桶壁板倾斜设置，且内桶的内腔自上而下逐步变小，本例中，外桶壁板和内桶壁板平行设置，这样一来，能够避免内外桶之间的相对转动，从而限定了内外桶只能上下相对运动。
由于以上技术方案的实施，本发明与现有技术相比具有如下优点：
本发明通过内桶与外桶相对活动的密封连接，一方面可根据实际使用需要灵活调节负压空腔的容量大小，提升吸尘能力和吸尘效率；另一方面，由于内桶和外桶之间可进行收折，占用空间小，便于存储和运输。

如图1所示，按照本实施例吸尘器的伸缩折叠桶，其包括外桶1、内桶2、内衬3、锁定件4。
具体的，外桶1包括外桶底板10、外桶壁板11。
本例中，外桶底板10呈方形，外桶壁板11有四块，并分别自外桶底板10的四条侧边倾斜向上延伸，且形成外桶1的内腔自上而下逐步变小。
结合图2所示，外桶底板10两侧长边所对应的外桶壁板11上分别形成有两个导向槽a1，导向槽a1自外桶壁板11底端沿外桶壁板11高度方向延伸，且每块外桶壁板11上的两个导向槽a1沿外桶底板10长边长度方向并排隔开设置。
具体的，内桶2上下活动在外桶1上。
结合图3所示，内桶2包括围成内桶腔的四块内桶壁板20，其中内桶壁板20倾斜设置，且内桶2的内腔自上而下逐步变小，同时与外桶1的内腔相贯通并形成吸尘腔q。
内桶壁板20与外桶壁板11一一对应，且内桶壁板20上形成有与导向槽a1一一对应的突起a2。这样设置，通过突起与导向槽的配合，使得内桶定位在外桶内，便于内桶与外桶间的相对活动。
本例中，伸缩折叠桶还包括密封件5。
具体的，该密封件5包括设置在内桶2和外桶1之间的密封条50，其中密封条50绕着内桶2的周向设置，且固定在内桶2的底部。这样一来，随着内桶相对外桶上下活动时，保证吸尘腔保持封闭状态，同时，不仅保证任意位置的内外桶之间密封，而且能够呈现最大化的吸尘腔容积。
结合图4所示，内衬3形成在外桶1内且绕外桶1内壁周向设置，其中内衬3自底部连接在外桶底板10上，同时内衬3的内腔和内桶2的内腔构成吸尘腔q。本例中，内桶2处于外桶1和内衬3之间。
因此，实际的吸尘腔q是由内桶2的内腔和内衬3的内腔组合而成，这样一来，内桶2和外桶1相对运动时(也就是内桶和内衬相对运动时)，上述的密 封条50可以与内衬3的外壁或/和外桶1的内壁抵触密封，同时，内桶2相对外桶1向上运动时，吸尘腔q逐步变大；内桶2向下运动时，吸尘腔q逐步变小。
本例中，内衬3自外桶底板10的上表面竖直向上延伸，并自底端形成有绕内衬3内壁周向设置的六个连接座s，内衬3自连接座s通过螺栓与外桶底板10相固定连接。
同时，内衬3顶部还设有绕内衬3顶部周向设置的限位边b2，其中限位边b2自内衬3的顶部水平向外延伸。
本例中，限位边b2沿着内桶2的内壁轮廓方向设置，且能够贴合在内桶2的内壁。当然，限位边b2不贴合内桶2的内壁也是可以实施的。
也就是说，当内桶2和外桶1处于极限展开状态时，密封条50贴合在内衬3的顶部且抵触在限位边b2的底部；当内桶2和外桶1处于完全折叠时，密封条50贴合在内衬3的底部且抵触在外桶1底部的内壁。这样设置，当吸尘腔容积最大时，能够快速确定内桶的位置，便于内桶与外桶之间相对锁定。
本例中，锁定件4包括第一锁合部40、第二锁合部41。
第一锁合部40有两组，且分别设置在外桶底板10两侧短边所对应的外桶壁板11内壁上，每组第一锁合部40包括具有上锁孔c1和下锁孔c2的锁座400。
第二锁合部41有两组，且分别固定设置在外桶底板10两侧短边所对应的内桶壁板20的外壁上并与第一锁合部40一一对应。
本例中，第二锁合部41包括锁舌410、及驱动锁舌410运动或复位的动力器411，其中在极限折叠状态时，锁舌410伸入下锁孔c2并配合锁定，在极限展开状态时，锁舌410伸入上锁孔c1并配合锁定。
结合图5所示，在内桶2的顶部形成连接边6，伸缩折叠桶还包括连接在连接边6上的桶盖7，吸尘器的机头8安装在桶盖7上且下部伸入吸尘腔q。使得结构更加紧凑，而且体积小，便于存储和运输。
吸尘器的机头8能够上下活动且密封的安装在桶盖7上。在满足收折体积小的前提下，进一步的减少机头占用吸尘腔的空间，以增大吸尘腔容积。因此，本实施例具有以下优势：
1、通过内桶与外桶或者内外桶与内衬或者内桶与内衬的相对活动的密封连接，可根据实际使用需要灵活调节负压空腔(也就是吸尘腔)的容量大小，提 升吸尘能力和吸尘效率；
2、占用空间小，便于存储和运输；
3、由吸尘器的机头与吸尘腔的位置关系，尤其在收折时，能够进一步减少吸尘器的体积，同时在吸尘工作时，机头既可以随内桶同步运动，又可以相对内桶伸缩运动，进而改变吸尘腔的容积，满足高效吸尘的需要；
4、结构简单，使用方便，再通过上下锁孔位置分布，实现吸尘腔大小的极限调节，暂开时，处于最大化状态；折叠时，处于最小化状态。
以上对本发明做了详尽的描述，其目的在于让熟悉此领域技术的人士能够了解本发明的内容并加以实施，并不能以此限制本发明的保护范围，凡根据本发明的精神实质所作的等效变化或修饰，都应涵盖在本发明的保护范围内。
