技术领域
本发明涉及手控真空吸尘器。
背景技术
便携式手控真空吸尘器可用来清洗家里、办公室、汽车等内的不同表面。这种手控真空吸尘器通常用于相对较小的清洗作业或用于难以到达地方的清洗。同样，这些真空吸尘器相对较轻并具有把手以使用户能在罐式、竖式的或店铺型真空吸尘器不能使用或不方便使用的场合轻易地使用真空吸尘器。通常，这种手控真空吸尘器是电池驱动的。
发明内容
在一个实施例中，本发明提供一种手控真空吸尘器，其包括：入口、出口和具有孔的灰尘杯。灰尘杯与入口和出口流体连通并配置成保留手控真空吸尘器所收集的碎片。风扇配置成通过入口和灰尘杯抽吸空气，并且通过出口排出空气。门邻接灰尘杯并包括入口。门在打开位置和闭合位置是可移动的，在打开位置，允许用户通过灰尘杯的孔倒出收集在灰尘杯内的碎片，在闭合位置，阻止碎片通过灰尘杯的孔倒出，并允许碎片通过入口和灰尘杯的孔被收集。偏置元件配置成将门偏向打开位置。

在详细解释本发明的任何实施例之前，应当理解的是，本发明不应限于应用到如下描述中提出的或如下图形所示出的构造细节和部件布置。本发明能用于其它实施例并能以不同方式实践或执行。
具体实施方式
图1图示了便携式手控真空吸尘器12。该真空吸尘器12包括联接到灰尘或泥土杯20的主外壳或风扇外壳16以及联接到灰尘杯20以用于倒空聚集在灰尘杯20内的碎片的门22。风扇外壳16在外壳16的前端26包括空气入口24(图2)并在入口24的后方包括空气出口28。风扇32(图3)置于风扇外壳16内，该风扇32可操作地用来通过入口24抽吸空气并通过出口28排放空气。外壳16进一步包括配置成驱动风扇32的马达。在一个实施例中，马达是由也置于风扇外壳16内的可再充电电池驱动的直流(DC)马达。在其他实施例中，风扇32可被无需再充电电池的交流(DC)马达驱动。开关36置于外壳16之上，靠近真空吸尘器12的主把手40。在图示的实施例中，开关36在“开”和“关”位置之间通常可以用户拇指滑动，以“开”和“关”风扇32，并因此“开”和“关”真空吸尘器。
参考图3，电触点44和释放锁48置于外壳16的前端26附近。电触点44用来为真空吸尘器12的配件工具(图2)提供电能，这将在下文作更详细地讨论。释放锁48包括突出部56，并且释放锁48可被用户按压，以把突出部56缩回外壳16内，以从外壳16断开灰尘杯20。突出部56容纳在灰尘杯20的孔60内，以联接灰尘杯20和外壳16。在图示的实施例中，突出部56配置成在灰尘杯20联接到外壳16时接触灰尘杯20，使得突出部56被自动地缩回，这就允许用户在不按压释放锁48的情况下再接合外壳16和灰尘杯20。
参考图4，灰尘杯20包括底壁64、自底壁64向上延伸的第一侧壁68、自底壁64向上延伸并相对于第一侧壁68的第二侧壁72。在侧壁68和72之间延伸并相对于底壁64的顶壁76。灰尘杯20的前孔80在灰尘杯的前端82通过顶壁76形成，后孔84(图3)在灰尘杯20的后端86由壁64、68、72和76限定。参考图3，图示的灰尘杯20进一步包括自顶壁76向上延伸的电触点防护装置88。电触点防护装置88包括接收外壳16的电触点44的孔92，以防止触点44受聚集在灰尘杯20内的碎片的影响。在图示的实施例中，壁64、68、72、76和触点防护装置88由塑料一体地形成为单一部件。
参考图4，图示的门22可枢转地联接到灰尘杯20，靠近顶壁76，使得门22通过绕轴线96枢转向上地打开。图示的门22使用铆钉100联接到灰尘杯20，但在其他实施例中，其他适宜类型的紧固件可用来将门22枢转地联接到灰尘杯20。在图示实施例中为扭矩弹簧的偏置元件104置于灰尘杯20和门22之间的各个铆钉100的周围，以向上地偏压门并偏向打开位置。
继续参考图4，真空吸尘器12进一步包括第一闩锁108和第二闩锁112，该锁将门保持在闭合位置以抵抗偏置元件104的偏压。第一闩锁108和第二闩锁112大体上是一样的，并因此，仅第一闩锁108将得到详细的讨论，并且相同部件由相同的参考数字给出。参考图6，闩锁108包括柱116，该柱116容纳在形成在灰尘杯20内的柱容纳孔120内，以可枢转地将闩锁108联接到灰尘杯20。闩锁108进一步包括在闩锁108处于接合位置时接合门22的突出部124，以便将门22保持在闭合位置。在图示构造中为卷簧的偏置元件128置于闩锁108和灰尘杯20之间，以将闩锁108偏压入接合位置。用户按压闩锁108(用户类似地按压第二闩锁112)以抵抗弹簧128的偏压，以将闩锁108转向突出部124不再将门22保持在闭合位置的分离位置，并且扭矩弹簧104(图4)将门22移向打开位置。
继续参考图4和图6，闩锁108和112在形成在灰尘杯20的各自侧壁68、72内的孔或凹槽132内被联接到灰尘杯20。凹槽132和闩锁108和112按规定尺寸制作，使得闩锁108和112在闩锁108和112处于接合位置时与各自的侧壁68和72平齐。
参考图2和图4，门22包括入口孔136，该入口孔136从门22的前端部140穿过门22的对立后端部144，其中，门22可枢转地联接到灰尘杯20。如图7和图10最佳地显示，盖148联接到门22的下侧，以在盖148和门22之间限定入口通道152。入口通道152在入口孔136和灰尘杯20之间提供流体连通。出口孔156被设置成通过盖148的后部，以在灰尘杯20和入口通道152之间提供流体连通。橡胶密封条160被联接到盖148以在门22处于闭合位置时在孔80(图4)的***周围密封盖148和灰尘杯20之间的界面。同样，盖148包括孔164(图7)，该孔164在门22处于闭合位置时接收闩锁108和112的突出部124(图4)，以将门22保持在闭合位置。孔164包括凸轮表面166，该凸轮表面166配置成接触闩锁108和112的突出部124，以在用户关闭门22时自动地移动闩锁108和112，使得门22可在用户不必直接操作或致动闩锁108和112的情况下被闭合并被保持在闭合位置。
参考图5和图10，图示的真空吸尘器12包括伸缩式喷嘴170，该喷嘴170与入口通道152流体连通并可移动地联接到门22，使得喷嘴170可被用户在伸出位置(图5)和回缩位置或凹入位置(图4)之间滑动。喷嘴170包括为喷嘴170和入口通道152提供流体通道的入口孔174。喷嘴170进一步包括由直立壁形成的把手178，该把手178为用户提供紧抓喷嘴170的适当位置，以使喷嘴170在伸出位置和缩回位置之间移动。门22的切块182在喷嘴170处于缩回位置时接收把手178。参考图5和图8，喷嘴170进一步包括突出部186。该突出部186与喷嘴170一体地形成为单一部件。突出部186在喷嘴170处于伸出位置时接合切块182，以将喷嘴170保持在伸出位置。用户向下地按压突出部186，以分离门22的突出部186和切块182，以将喷嘴170滑入凹入位置。
参考图2，图示的真空吸尘器12包括配件工具52。图示的门22包括位于门22的前端部140附近的终端孔188。电触点190位于终端孔188内，并且电触点190使用电线195电联接到电触点194(图7)。电触点194在门22的后端144附近被联接到门22的下侧150，并且电触点194在门22处于闭合位置时接合外壳16的电触点44(图3)，以便在真空吸尘器处于“开”状态时将电能提供给孔188内的终端190。
参考图2，配件工具52包括出口管路204和置于管路204附近的一对终端208。突出部212置于终端208之间。为了将配件工具52联接到真空吸尘器12，管路204被***在伸缩式喷嘴170的入口孔174内。在喷嘴170处于缩回位置(图2)时，工具52的终端208被容纳在门22的终端孔188内，该终端将配件工具52的马达与真空吸尘器12的电源电联接起来。尽管图示的配件工具52包括用于电马达的终端208，但在其他实施例中，配件工具可被气涡轮驱动，并且在其他实施例中，配件工具可不包括驱动元件比如马达或气涡轮。
继续参考图2，当配件工具52被连接到真空吸尘器12时，配件工具52的突出部212被容纳在门22的凹槽218内。突出部212接合凹槽218，以将工具52联接到真空吸尘器12，尤其在工具52沿图1的箭头222的方向沿工作面推动时，以便阻止管路204从喷嘴170中拉出。
参考图1和图2，为了从真空吸尘器12移除配件工具52，用户轻微地转动配件工具52以分离突出部212和凹槽218。然后，用户拉动配件工具52，以将工具52的管路204拉出喷嘴170。在图示的实施例中，喷嘴170和门22之间的摩擦大于管路204和喷嘴170之间的摩擦，使得喷嘴170在用户移除工具52时保持在凹入位置内(图1和图2)，并且工具52的移除不使喷嘴170扯入伸出位置。在其他实施例中，机械锁可用来在用户从喷嘴170移除配件工具52时将喷嘴170保持在凹入位置。
参考图3和图10，真空吸尘器12进一步包括第一过滤器230和第二过滤器234。第一过滤器230包括金属丝网筛238、密封条244和后孔248。第二过滤器234包括褶状过滤器介质252。第二过滤器234容纳在第一过滤器230的后孔248内，以联接第一过滤器230和第二过滤器234。第一过滤器230和第二过滤器234通过后孔84一起置于灰尘杯20内。密封条244密封第一过滤器230的***和灰尘杯20的壁64、68、72和76，使得通过灰尘杯20的空气大体上流过第一过滤器230，然后在不旁通过滤器230和234的情况下流过第二过滤器234。
参考图3、图5和图10，在操作中，用户抓住真空吸尘器12的把手40，并将开关36滑动到“开”位置，这就使风扇32(图3)在灰尘杯20内产生真空。因此，空气和碎片通过门22的入口孔136(或通过图示实施例的喷嘴170的入口174)被抽吸出，并进入入口通道152。空气和碎片穿过入口通道152并通过盖148的出口孔156，并进入灰尘杯20。相对重的碎片落入灰尘杯20的底部，同时相对轻的碎片继续随空气流运动。相对轻的、粗糙的碎片被第一过滤器或网筛230过滤。然后，相对轻的、精细的碎片被第二过滤器234的褶状过滤器介质252过滤。清洁的过滤空气然后通过风扇外壳16的入口24(图3)被风扇32吸入，并且通过出口28从真空吸尘器12排出。
参考图4和图11，如果用户需要倒空灰尘杯20，用户按压闩锁108和112，以将闩锁108和112移动到分离位置(被图11的虚线108描述)，这就使弹簧104绕轴线96向上地枢转门22，并转向打开位置。然后，用户向下倾斜灰尘杯20的前端，以通过灰尘杯20的前孔80倒出碎片。同时，门22被弹簧104保持打开，使得用户不必保持门22打开，这就使用户剩下自由的手以便于倒空和清洗真空吸尘器12。同样，如图4中所见，向上打开的门22(包括联接到门22的喷嘴170)通过灰尘杯20的前孔80提供相对清晰的通道，以允许通过孔80的灰尘杯20的轻易倒空。由于门22处于打开位置，孔80也为用户提供到第一过滤器230的通路，以便用户在需要时可清洗过滤器230。如上所讨论的，用户可关闭门22以重新清洗。可备选地，参考图3，用户可通过后孔84倒空灰尘杯20。用户可按压释放锁48，这就缩回突出部56以从孔60抽回突出部56，以从外壳16断开灰尘杯20。然后，用户可通过后孔84移除过滤器230和234，以通过灰尘杯20的后孔84清洗过滤器并倒空碎片。
