Description

喷雾器
技术领域
本发明涉及一种所说明的类型的喷雾器(Spruehgeraet)，其带有用于驱动鼓风机的驱动马达，带有吹管，通过吹管由鼓风机输送空气流，带有布置在背部支架处的喷雾剂箱，且带有喷嘴，喷嘴通过喷雾剂管道与喷雾剂箱相连接且给空气流供给喷雾剂。
背景技术
由文件WO 2010/008374A1已知一种背携式的(rueckengetragen)送风机(Blasgeraet)，在其中由于在喷嘴处所产生的负压，喷雾剂(Spruehmittel)被配量给空气流。在喷嘴处形成的负压一方面取决于马达转速且另一方面取决于喷嘴关于喷雾剂箱布置的高度。在操作中，使用者不仅可向下而且可向上喷洒。通过吹管的竖直的摆动运动产生在喷嘴与喷雾剂箱之间的高度差的区别和因此在喷嘴处的静液压力的改变，静液压力明显影响所供给的喷雾剂量。
也已知通过泵将喷雾剂输送到吹管中。然而，喷雾器的构造由此变得更加复杂，且由于附加的零件增加了喷雾器的重量。
发明内容
本发明的目的在于提供这种类型的喷雾器，其结构简单且确保均匀的喷雾剂排出(Spruehmittelaustrag)。
该目的通过这种喷雾器来实现，其特征在于，在喷嘴上游在喷雾剂管道中布置有压力调节器。
通过在喷雾剂管道中的压力调节器可调整由于吹管在操作中在摆动时不同的工作高度而产生的压力差。在恒定的压力下，压力调节器给喷嘴供给喷雾剂。不需要单独的泵。喷雾剂可只根据在出口喷嘴 处的负压和在喷雾剂箱与喷嘴之间的大地测量学的压力差来配量。
有利地，空气流通过排出口离开吹管。压力调节器和喷嘴尤其相邻于排出口地布置在吹管处。通过压力调节器和喷嘴彼此直接相邻地布置，由于在压力调节器与喷嘴之间的高度差的压力差最小。喷嘴相邻于排出口的布置引起良好的喷雾剂排出。
有利地，在压力调节器与喷嘴之间在喷雾剂管道中布置有用于喷雾剂的配量装置。压力调节器相应地布置在配量装置上游。配量装置有利地直接相邻于喷嘴布置。
有利地，压力调节器具有停止运转位置(Ausserbetriebsstellung)。由此，容器通过配量装置的清空是可能的。在它的运转位置中，压力调节器由于压力比截止通过压力调节器的流动，使得喷雾剂容器的清空是不可能的。
压力调节器有利地构造成膜片式调节器。压力调节器尤其具有调节腔、限制调节腔的调节膜和到调节腔中的进口阀，进口阀的位置关联于调节膜的位置。在此，进口阀有利地被弹性加载到其闭合方向上。可作如下设置，即，调节膜的背对调节腔的侧面被加载以环境空气。特别有利地，调节膜的背对调节腔的侧面与喷雾剂箱的内腔相连接。由此，在喷雾剂箱的内部中的压力充当参考压力。当喷雾剂箱被压力加载且喷雾剂箱中的压力偏离于环境压力时，那么这尤其是有利的。
当压力调节器具有操作元件(其在停止运转位置中偏转调节膜且由此打开进口阀)时，得到一种简单的构造。调节膜相应地由操作元件不依赖于在调节膜处存在的压力比地按压到进口阀的开启位置中。
为了实现喷雾剂的良好的输送，作如下设置，即，喷雾剂箱被压力加载。这可以以简单的方式由此来实现，即，喷雾剂箱通过压力管道与鼓风机的过压区域相连接。有利地，鼓风机具有布置在鼓风机螺旋中的鼓风机叶轮。压力管道尤其通到鼓风机螺旋的过压区域中。
在工作停止时，操作者放开节气门杆，使得驱动马达和鼓风机叶轮的转速下降。由此，在鼓风机螺旋中仅还产生较小的过压。因此， 喷雾剂箱中的压力也非常迅速地下降。如果操作者重新给气，则喷雾剂箱中的压力首先须被再次建立。为了减少时间延迟，在压力管道中可布置有朝向喷雾剂箱开启的止回阀。由此减少在喷雾剂箱中的压力降低。
当压力调节器通过至少部分地包围吹管的固定夹被固定在吹管处时，得到一种结构简单的设计。如此设计的压力调节器对于现存的喷雾器也可以以简单的方式来加装。

具体实施方式
图1显示了一种背携式的喷雾器1。喷雾器1具有背部支架2，在背部支架2处固定有未示出的肩带，利用肩带可由使用者在背部上携带背部支架2。在背部支架2处固定有壳体3，在壳体3中布置有驱动马达4，其驱动鼓风机45。驱动马达4构造为内燃机、尤其为两冲程发动机或为经混合润滑的四冲程发动机。在内燃机4下方布置有燃料箱5，其可被集成到壳体3中或可构造成单独的壳体件。在壳体3上方，在背部支架2处固定有喷雾剂箱8。在喷雾剂箱8中，液态的喷雾剂被填充直至填充高度16。喷雾剂箱8由箱盖9封闭。
鼓风机45具有鼓风机螺旋7，其被集成在壳体3中且在其处联接有吹管11。在吹管11处固定有手柄12，在手柄12处布置有用于操作驱动马达4的节气门杆13。吹管11具有波纹管截段14，使得吹管11在操作中可被摆动，如通过箭头15所示意性地标明的那样。鼓风机45通过吹管11输送空气流，其通过排出口44离开吹管11。在排出口44上游且在吹管11中以至排出口44较小的距离布置有喷嘴17。喷嘴17通过喷雾剂管道19与喷雾剂箱8的内腔相连接。相邻于喷嘴17布置有配量装置10，其可由操作者手动调整。在配量装置10上游 且直接相邻于配量装置10和排出口44在喷雾剂管道19中布置有压力调节器18，其功能以下还将详细进行阐述。填充高度16相对于喷嘴17在所显示的吹管位置中具有高度差Δh。由此，在喷雾剂箱8与喷嘴17之间产生喷雾剂的压力差。如果吹管11被转移到图1中虚线画出的上部的位置中，则喷嘴17大约处于填充高度16上，使得在喷嘴17处的静液压力对应于喷雾剂箱8中的压力。在喷嘴17处的压力明显小于在吹管11的下面的位置中。
图2示意性地显示了压力调节器18的功能和构造。压力调节器18布置在喷雾剂管道19中且具有调节腔23，喷雾剂管道19从喷雾剂箱8通过进口阀26通到调节腔23中。进口阀26布置在杠杆25处，杠杆25在进口阀26的闭合位置的方向上由弹簧27加载。杠杆25以其背对进口阀26的侧面贴靠在调节膜24处。调节膜24限制调节腔23且将它与补偿腔36分开。在补偿腔36中存在压力调节器18的参考压力。在实施例中，补偿腔36通过补偿管道22与喷雾剂箱8的内腔相连接，使得在补偿腔36中存在与在喷雾剂箱8中相等的压力。
有利地，喷雾剂箱8被压力加载。为此设置有在图2中所显示的压力管道20，其通到鼓风机螺旋7的过压区域中。也如图2所示，鼓风机45包括旋转地驱动的、布置在鼓风机螺旋7中的鼓风机叶轮6。鼓风机叶轮6构造成风扇叶轮且通过吹管11输送工作空气。在压力管道20中布置有止回阀21，其在朝向喷雾剂箱8的方向上开启。在鼓风机螺旋7中的压力下降时，例如当操作者不给气时，喷雾剂箱8中的压力尽可能保持，使得在重新给气时在喷雾剂箱8中已经存在过压而它不须才被建立。
在运行中，在压力调节器18下游的喷雾剂管道19的区域中存在大致恒定的压力。压力的高度通过压力调节器18的设计(例如弹簧27的设计)在结构上预先给定。因此在吹管11的位置的较远的区域中配给吹管11的喷雾剂量仅依赖于空气流，即依赖于驱动马达4的转速。仅当喷嘴17在喷雾剂箱8未经压力加载的情况下布置在填充高度16 上方且在喷雾剂箱8经压力加载的情况下明显布置在填充高度16上方时，在压力调节器18下游的喷雾剂管道19中的压力才下降，这是因为在压力调节器18被完全打开的情况下压力水平也不再能被平衡。
图3显示了大致与根据图2的实施例相符的实施例。然而，在根据图3的实施例中补偿腔36朝向环境而不朝向喷雾剂箱8开启。在根据图3的实施例中，在压力管道20中未布置有止回阀21，使得当操作者不给气时喷雾剂箱8中的压力快速下降。也可作如下设置，即，喷雾剂箱8不被压力加载，使得也可不用考虑压力管道20。
图4详细地显示了压力调节器18的构造。压力调节器18具有调节器壳体28，在其外侧处布置有操作元件29，其实施成摆动杆。操作杆29可在压力调节器18的停止运转位置30与压力调节器18的运转位置31之间被摆动。中间位置(在其中调节器的运行被限制)也可以是有利的。在调节器壳体28处通有进口接口34以及补偿接口33。此外，出口接口35从调节器壳体28中引出。在调节器壳体28处，在背对操作元件29的侧面处模制有固定夹32，利用固定夹32可在无附加的固定元件的情况下将压力调节器18夹紧在吹管11处。固定夹32由于调节器壳体28的塑料的固有弹性将调节器壳体28固定在吹管11处。图4中所显示的固定夹32具有开口，通过该开口固定夹32可在吹管11上被移动。固定夹32仅部分地围绕吹管11。
如图5所示，为了确定操作元件29的停止运转位置30在调节器壳体28处模制有锁销39。
如图6中的剖面图所示，相应的锁销39设置用于运转位置31。操作元件29处在锁销39上方的相应的位置中且搭接锁销，以便确定止动位置。也如图6所示，调节器壳体28具有上部的壳体外壳37(操作元件29布置在其处)以及下部的壳体外壳38(进口接口34和出口接口35构造在其处)。调节腔23构造在上部的壳体外壳37中，而补偿腔36构造在下部的壳体外壳38中。在两个壳体外壳37与38之间，调节膜24被夹持。两个壳体外壳37和38彼此拧紧。操作元件29通 过螺纹40被保持在上部的壳体外壳37中。在图6中所显示的运转位置31中，调节膜24在压力调节器18的未加载的状态中贴靠在操作元件29处且未被偏转。在面对操作元件29的侧面处，杠杆25布置在调节膜24处。
如图7所示，杠杆25可摆动地支承在壳体28中的摆动支座41处。在背对调节膜24的端部处，在杠杆25处固定有阀体42，其在闭合的位置中被压向阀座43且利用其形成进口阀26。在杠杆25与下部的壳体外壳38之间布置有弹簧27。弹簧27相对于操作元件29布置在杠杆25处。
如图8所示，操作元件29在停止运转位置30中被进一步拧入调节器壳体28中。在该位置中，操作元件29偏转调节膜24。由此，杠杆25摆动且阀体42从阀座43提起。进口阀26在该位置中被打开，使得喷雾剂可无阻碍地流动通过压力调节器18。
