Description
本发明涉及农业作业领域，尤其涉及一种喷洒装置及无人飞行器。
随着科技的不断发展，越来越多的自动控制设备应用在了农业作业当中。
目前，为了向农作物进行农药等药剂的喷洒，可以通过自动喷头以离心的方式喷洒药剂。具体的，自动喷头中包括有一个转子轴和可以在转子轴带动下旋转的甩盘，药剂通过内部通道进入甩盘后，即可在甩盘高速旋转的离心力作用下将向外呈雾状分散甩出，达到均匀喷药的效果。为了向甩盘中供应药剂，通常可以采取驱动机构进液或者侧边进液的方式，让药液从驱动机构的内部或者驱动机构的侧边流入甩盘之中。
然而，由于药液的腐蚀和转动磨损等原因，驱动机构内的线圈绕组等部件较易产生损坏。当喷头采用驱动机构内部进液的方式，喷头结构较为复杂；而采用侧边进液的方式时，喷头通常为一体式结构而不易拆卸，这样均会造成喷头拆装不便，不利于喷头的维修和零件更换。

第二方面，本发明提供一种无人飞行器，包括机体和如上所述的喷洒
装置。
本发明的喷洒装置及无人飞行器，喷洒装置包括具有可绕自身轴线旋转的驱动轴的驱动机构和设置在驱动轴的底部的甩盘，甩盘用于在驱动轴的旋转带动下转动并喷洒药液，驱动机构包括定子组件、转子组件和外壳组件，外壳组件包括第一外壳件和第二外壳件，第一外壳件和定子组件连接，转子组件与第二外壳件连接，且第一外壳件与第二外壳件卡合连接，第二外壳件的底部侧方设置有与甩盘内部连通的进水通道。这样喷洒装置能够方便的进行拆卸，且结构简单，与药液的隔离性较好。

为使本发明实施例的目的、技术方案和优点更加清楚，下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
图1是本发明实施例一提供的喷洒装置的爆炸示意图。图2是本发明实施例一提供的喷洒装置的截面示意图。图3是本发明实施例一提供的喷洒装置中定子组件的结构示意图。图4是本发明实施例一提供的喷洒装置中第一外壳件的结构示意图。图5是本发明实施例一提供的喷洒装置中第二外壳件的结构示意图。图6是本发明实施例一提供的喷洒装置中第二外壳件的侧视图。图7是本发明实施例一提供的喷洒装置中第二外壳件的俯视图。图8是图7中A-A截面的截面示意图。如图1至图8所示，本实施例提供的喷洒装置，包括具有可绕自身轴线旋转的驱动轴的驱动机构1和设置在驱动轴的底部的甩盘2，甩盘2用于在驱动轴的旋转带动下转动并喷洒药液，驱动机构1包括定子组件11、转子组件12和外壳组件，外壳组件包括第一外壳件13和第二外壳件14，第一外壳件13和定子组件11连接，转子组件12容置在第二外壳件14内，且第一外壳件13与第二外壳件14卡合连接，第二外壳件14的底部侧方设置有与甩盘2内部连通的进水通道。
具体的，喷洒装置主要用于通过旋转时的离心力将药液呈雾状向四周均匀甩出，以达到均匀喷药的目的。为了让药液离心甩出，喷洒装置包括有能够驱使甩盘旋转的驱动机构1，驱动机构1中包括有可绕自身轴线旋转的驱动轴，甩盘2位于驱动轴的底部，因而驱动轴转动时，即可带动下方的甩盘2同步产生旋转，从而向四周喷洒药液。
为了驱动甩盘2旋转，驱动机构1包括有定子组件11、转子组件12和用于固定定子组件11以及转子组件12的外壳组件。其中，外壳组件为分体式结构，其中包括有第一外壳件13和第二外壳件14，第一外壳件13和第二外壳件14可以分别与定子组件11或者转子组件12连接，且第一外壳件13和第二外壳件14之间为可拆卸的卡合连接。这样，定子组件11及转子组件12分别设置于外壳组件的对应的部分上，因而通过分离第一
外壳件13以及第二外壳件14，可以较为容易的将驱动机构1中的定子组件11与转子组件12相互拆开，以便于进行定子组件11与转子组件12的分别维修与部件更换。
其中，为了避免驱动机构遭到药液的侵蚀，用于供药液流通的进水通道设置在第二外壳件14的底部侧方，这样进水通道位于定子组件11以及转子组件12的外侧，因而药液与驱动机构1相互隔离，不会进入驱动机构1内部并对驱动机构1造成腐蚀，喷洒装置的整体耐腐蚀性和使用可靠性较好。
因此，通过将驱动机构1中的定子组件11以及转子组件12分别设置在第一外壳件13与第二外壳件14上的方式，能够形成模块化的定子组件11以及转子组件12，在简化装置整体结构的同时，方便的进行喷洒装置的拆卸与安装；同时，用于和甩盘2连接的进水通道设置在外壳组件的底部侧方，因而药液的通路不与驱动机构1内部连通，整个装置具有较好的耐腐蚀性和可靠性。
为了便于第一外壳件13与第二外壳件14之间的快速拆装，作为一种可选的连接方式，第一外壳件13和第二外壳件14之间可以旋转卡合。这样，第一外壳件13和第二外壳件14位于预设的相对位置后，通过让第一外壳件13与第二外壳件14相对旋转，即可实现第一外壳件13与第二外壳件14之间的卡合或者解除卡合。这样通过简单的操作即可完成卡接，卡接过程较为简便。
一般的，在驱动机构1，尤其是定子组件11中通常会设置有线圈绕组和其它电气元件，而为了避免药液通过进水通道进入甩盘2的过程中对线圈绕组等造成影响，进水通道通常可以位于定子组件11的下方。这样定子组件11的高度高于进水通道所在的高度，即使药液流至定子组件11的下方，也会因为重力作用而向下流动，而无法接触到位于上方的定子组件11，这样定子组件11不会受到药液的腐蚀，安全性和可靠性较高。
为了分别设置定子组件11和转子组件12，同时实现可拆卸的卡合连接，外壳组件中的第一外壳件13和第二外壳件14相应的具有多种可能的结构及实施方式，以下对此进行具体说明。
作为一种可选的实施方式，第二外壳件14可具有顶端开口的中空腔
体141，转子组件12设置在该中空腔体141内。此时，转子组件12被中空腔体141所容纳，因而得到了第二外壳件14的保护，此外，由于转子组件12受到中空腔体141的支撑，因而也实现了与第二外壳件14之间的连接和固定。其中，中空腔体141的形状通常可以和转子组件12的外形相匹配，以使转子组件12稳固的放置于第二外壳件14内。
可选的，转子组件12通常包括有转子轴121和与转子轴121固定连接的转子盖122，转子轴121的轴心与驱动轴的轴心重合。其中，转子轴121可以作为驱动轴的主体和甩盘2连接，并驱动甩盘2绕转子轴121的轴线旋转，而转子盖122用于和定子组件11耦合，以在同定子组件11之间的电磁力作用下带动转子轴121产生旋转。一般的，转子盖122可以环绕在转子轴121外侧，且转子盖122的下部与转子轴121连接，而转子盖122的上部与转子轴121之间间隔设置并具有向上的开口，以用于容纳定子组件11的相应部分。
此外，可选的，转子组件12还包括磁铁和磁轭中的至少一种。磁铁和磁轭能够产生磁场力，并在与定子组件11的相互作用下产生驱动转子组件12旋转的动力。一般的，转子组件12中的磁铁和磁轭通常对应设置在转子盖122上。
进一步的，为了让转子组件12中的转子轴121方便的与甩盘连接，第二外壳件14的底面可开设有通孔142，转子盖122设置在中空腔体141内，且转子轴121的底端从通孔142内穿出。这样转子轴121能够从第二外壳件14的底部伸出，并与下方的甩盘2连接。由于转子组件12会相对于定子组件11旋转，所以第二外壳件14与转子组件12之间的连接处可以设置有轴承，以使转子组件12相对于第二外壳件14自由旋转。
因为转子轴121的底部末端一般会直接和甩盘2连接，而甩盘2的中空通道中容纳有喷洒用的药液。当甩盘2在转子轴121的带动下转动时，药液可能因自身的粘性而粘在转子轴121的外圆周面上，并在转子轴121的旋转带动下向上移动，并溅入驱动机构1内部。为了避免药液随转子轴121的旋转而向上移动，转子轴121的外圆周面上可以设置有以转子轴121轴心为回转轴线的螺旋结构，螺旋结构的旋向与驱动轴的旋转方向相反。这样当药液随转子轴121的旋转而产生上升趋势时，螺旋结构会挡在药液
的前进路线上，从而避免药液继续向上移动；同时，受到螺旋结构阻挡的药液也会顺着螺旋结构呈螺旋式下落至转子轴121底部，而不会积留在转子轴121的外圆周面上。
通常的，螺旋结构为绕设在转子轴121外圆周面上的螺旋状凸起，或者是在转子轴121外圆周面上所开设的螺旋槽，此外，螺旋结构也可以为其它本领域技术人员所熟知的结构，此处不再赘述。
而为了向甩盘2内部提供药液，可选的，第二外壳件14上设置有进水通道143，且进水通道143的进水口可以位于第二外壳件14的侧方，进水通道143的出水口位于第二外壳件14的底部且与通孔142位于同一高度，出水口和通孔142之间相互隔离。这样由于进水通道143的出水口位于第二外壳件14底部，且与第二外壳件14中的通孔142以及中空腔体141均相互隔离，能够有效隔绝药液与中空腔体141内所设置的转子组件12，避免转子组件12受到药液的腐蚀。
为了让甩盘2的周向上均能够通入药液，第二外壳件14的底部还设置有与出水口连通的环腔144，环腔144绕设在通孔142外侧。这样药液从进水通道143的出水口流入环腔144内后，即可填充环腔144内的各区域，并由环腔144流向甩盘2周向上的各个方向，使甩盘2周向上均能够甩出药液。
进一步的，环腔144在靠近出水口一侧的宽度通常可以小于远离出水口一侧的宽度。这样，环腔144在靠近出水口一侧的大小会小于远离出水口一侧的大小，因而环腔144的大小能够补偿自身与出水口的距离不同而造成的流量差，这样药液在流出时会较为均匀，保证甩盘2周向的各个方向上均匀出液。
而为了和第一外壳件13之间实现卡合连接，第二外壳件14的周向外缘可以为回转面，且第二外壳件14的侧面设置有至少一个用于和第一外壳件13卡合的第一凸起145。这样第二外壳件14可以设置在第一外壳件13的内部或内侧，并通过旋转而与第一外壳件13卡合在一起。其中，为了保证与第一外壳件13之间均匀受力，第一凸起145的数量通常为多个。
由于第一外壳件13可以将第二外壳件14容纳在其内部，所以相应的，第一外壳件13可以具有用于容纳定子组件11与转子组件12的环形腔体
131。此时，不仅定子组件11容纳在第一外壳件13中，而且转子组件12也可以至少部分的随第二外壳件14而容纳在第一外壳件13的内部。
进一步的，环形腔体131的内壁上开设有用于和第一凸起145卡合的第一卡槽132。此时，第二外壳件14可以容置在环形腔体131的内部，且第一凸起145可以和第一卡槽132相互卡合，以将第二外壳件14固定在第一外壳件13的环形腔体131内部。
为了让第一外壳件13与第二外壳件14之间在周向的各个方向上均能够实现卡合连接，第一卡槽132的数量为至少两个，且第一卡槽132与第一凸起145一一对应设置。这样通过多个第一卡槽与第一凸起之间的连接，能够分散单个第一凸起145与第一卡槽132所受到的力，同时多个分布在不同位置的第一卡槽132与第一凸起145也能够确保受力均匀，避免因单个第一凸起145与第一卡槽132之间的卡合力过大而造成无法拆装甚至卡接结构损坏的现象发生。一般的，可以让第一卡槽132和第一凸起145均绕驱动轴的周向均匀间隔排布。
为了简化第一外壳件13与第二外壳件14之间的卡合操作过程，第一外壳件13与第二外壳件14之间通常为旋转卡合的方式实现连接。因此，为了实现两者之间的旋转卡合，第一卡槽132通常为旋转卡槽。这样第一凸起145可以通过与第一卡槽132之间的卡入和旋转而完成整个卡合过程，整个卡合操作过程较为简便。
具体的，第一卡槽132为旋转卡槽时，第一卡槽132可以包括开口朝向环形腔体131底部的开口段132a以及与开口段132a连通的卡合段132b，卡合段132b沿环形腔体131周向延伸，卡合段132b用于在第一外壳件13与第二外壳件14相对旋转时，与通过开口段132a进入第一卡槽132的第一凸起145在转子轴1轴向上相互卡合。这样当第一凸起145要卡入第一卡槽132之中时，第一凸起145可先通过开口段132a进入第一卡槽132内部，然后将第一外壳件13与第二外壳件14之间相对旋转，以使第一凸起145沿第一卡槽132的卡合段132b移动至第一卡槽132的内部，这样第一卡槽132的卡合段132b即可卡在第一凸起145的两侧，从而避免第一凸起145从第一卡槽132内脱离，确保第一外壳件13和第二外壳件14之间处于相互卡合的位置。通常的，在卡合段132b的末端通常设置有卡
突结构或是与第一凸起145之间具有较大的摩擦力，以避免第一凸起145沿卡合段132b从第一卡槽132中反向脱出。
其中可选的，为了让第一凸起145和第一卡槽132在沿驱动轴的轴向上将第一外壳件13和第二外壳件14卡合在一起，第一卡槽132中，开口段132a的延伸方向为沿驱动轴的轴向，且卡合段132b的延伸方向与驱动轴的轴向垂直。这样卡合段132b的槽壁即可卡在第一凸起145的侧方，避免第一外壳件13与第二外壳件14沿驱动轴的轴向方向相互脱离。这样，利用第一凸起145和第一卡槽132之间的卡合，即可让第二外壳件14固定在第一外壳件13上，避免第二外壳件14沿轴向脱离第一外壳件13。
通常的，开口段132b的开口大小一般与第一凸起145的大小相互匹配。例如，开口段132b的开口大小可以略大于第一凸起145的大小，从而方便第一凸起145进入第一卡槽132之中，同时避免第一凸起145从第一卡槽132内随意脱离。
可选的，第一外壳件13可以为多种外形，例如作为一种可选的实施方式，第一外壳件13可以为环形体。这样第一外壳件13具有较为简洁的外形，结构较为简单，成本较低。
当第一外壳件13为环形体时，由于第一外壳件13和第二外壳件14之间通常为旋转卡接的方式实现卡合，这样在卡合过程中，第一外壳件13与第二外壳件14之间会发生相对旋转。因而作为一种可选的结构，第一外壳件13的外圆周面上可以设置有防滑纹或者防滑凸起。当用户需要旋转卡合时，即可方便的握持第一外壳件13的外圆周面，以将第一外壳件13与第二外壳件14卡合在一起或者解除两者的卡合状态。
而可选的，为了提高喷洒装置的拆装速度和方便性，定子组件11与第一外壳件13之间通常为卡接连接。卡接连接的方式能够让定子组件11快速而方便的由第一外壳件13上拆下，从而实现部件之间的快速分离。
具体的，定子组件11可以包括定子座111等多个组成部件，其中，定子座111可以作为定子组件11中的主要结构部件，用于设置定子组件11中的其它部件。此时，定子组件11中的定子座111可以和第一外壳件13之间相互卡接。
而作为其中一种可选的卡接方式，第一外壳件13和定子座111中的
一者设置有第二卡槽，另一者设置有可卡入第二卡槽中的第二凸起。因而通过第二凸起与第二卡槽之间的相互卡合，即可让第一外壳件13和定子座111连接在一起。
为了减小第一外壳件13的体积和重量，第一外壳件13通常为薄壳类零件。此时，可以在第一外壳件13的顶部设置有第二凸起133，而在定子座111的周缘设置有用于与第二凸起133卡合的第二卡槽1111。这样第一外壳件13上不必设置卡槽，因而第一外壳件13能够具有厚度较薄的壳壁，从而有效减小其重量和体积。同时，因为定子座111的下部通常设置有用于与转子组件12相耦合的其它部件，因而第二凸起133设置在第一外壳件13的顶部时，所以第一外壳件13可以通过第二凸起133与定子座111连接并罩设在定子座111的下半部外侧，从而有效的对定子座111上的其它部件进行遮蔽和保护。
其中，第二凸起133的凸起方向可以垂直于转子轴1的轴向。这样第二凸起133的端部会沿着垂直于转子轴1轴向的方向卡在第二卡槽1111中，此时，通过第二凸起133与第二卡槽1111之间的连接，第一外壳件13可以挂在定子座111的外侧。同时，第二外壳件14通过卡接方式固定在第一外壳件13上，因而整个外壳组件的重量均由定子座111所承担。
同样的，和第一凸起145以及第一卡槽132之间的连接类似，为了让定子座111在周向上均匀承担外壳组件以及转子组件12的重量，第二凸起133与第二卡槽1111的数量均为多个，且第二凸起133与第二卡槽1111均沿转子轴1的圆周方向均匀排布。此时，多个第二凸起与第二卡槽之间的配合能够有效分担外壳组件和转子组件12的重量，避免单个第二凸起133与第二卡槽1111之间因承担力度过大而造成拆装困难或者卡接结构损坏的情况发生。
此外，定子组件11中除了定子座111外，还可以包括绕组112等部件。绕组112一般由线圈绕成，当绕组112中通电时，即可因绕组112的形状而产生具有方向性的电磁场，该电磁场即可推动转子组件12实现旋转。一般的，绕组112可以设置在定子座111的下半部分区域。
具体的，绕组112设置在定子座111的底部，且绕组112在驱动轴轴向上的位置与转子组件12在驱动轴轴向上的位置相对应。此时，绕组112
的位置与转子组件12的位置相对，因而绕组112所产生的电磁场能够恰好作用于转子组件12上。其中，绕组112的位置可以与转子组件12中的转子盖122的位置相对，且转子组件12和定子组件11装配完成时，绕组112通常会位于转子盖122和转子轴121之间的位置。
为了避免药液通过外壳组件的缝隙泄漏至定子组件11上，并腐蚀定子组件11中的绕组112或者使绕组112的线圈发生短路，在绕组112外还可设置有遮蔽结构。具体的，作为其中一种可选的方式，在绕组112外侧可以包裹有隔离物(图中未示出)。隔离物可以密封在绕组112的外侧，并能够防止外界的药液或者其它液体透过隔离物接触到绕组112，从而能够进一步保护绕组免受药液的影响。
可选的，作为隔离物的其中一种实施方式，绕组112外侧可以包裹有防水隔离胶。防水隔离胶能够密封在绕组112外侧，并将绕组112与外界隔离开来，从而起到防水密封效果。此外，本领域技术人员可以理解的是，隔离物除了防水隔离胶外，也可以为防水胶带或者泡沫状防水材料等能够防水及绝缘的密封材料，此处不再赘述。
此外，定子组件11中还可以包括电子调速器(图中未示出)等部件。其中，电子调速器可以用于调整转子组件12的转速，进而控制甩盘2对药液的喷洒速率。将电子调速器等部件集成在定子组件11上，一方面可以提高喷洒装置的结构紧凑性，另一方面也有利于定子组件11的模块化，便于实现不同模块的拆卸和更换。
一般的，喷洒装置通常会设置在其它装置或系统之上，因而喷洒装置需要通过连接结构与其它装置和结构进行连接。其中，由于外壳组件连接在定子组件11上，且转子组件12设置在外壳组件中的第二外壳件14上，因而整个喷洒装置均由定子组件11进行支撑。此时，作为可选的结构，喷洒装置还可以包括安装座3，安装座3和定子组件11之间可拆卸连接。这样安装座3即可作为连接件连接在其它结构之上。
其中，安装座3可以具有底部敞口的套筒部31，这样定子组件11的顶部能够伸入套筒部31的中空腔体中，并与安装座3之间可拆卸连接。其中，定子组件11与安装座3之间的连接方式可以为螺纹连接或者卡接等。
由于整个喷洒装置均通过安装座3与外界结构进行连接，因而定子组件11与安装座3之间的连接需要承担较大的重量和振动。为了提高定子组件11与安装座3之间的连接可靠性，安装座3和定子组件11通过至少一个螺纹紧固件32连接。螺纹紧固件能够承担较大的负载，且自身的抗振动性能较好，能够有效实现定子组件与安装座之间的连接。在本实施例中，安装座3和定子组件11之间通过四个螺纹紧固件32进行连接，且四个螺纹紧固件32两两相对设置在安装座3两侧，以提高螺纹紧固件32的连接强度。
其中，由于定子组件11的顶部伸入套筒部31的中空腔体内，所以螺纹紧固件32的安装方向一般与驱动轴的轴向相互垂直，即穿过套筒部31的侧壁而连接在定子组件11上。
具体的，可以套筒部31的壁上开设有第一安装孔，而在定子组件11的顶部设置有与第一安装孔相对的第二安装孔，此时，螺纹紧固件32即可同时穿设在第一安装孔以及第二安装孔中，以将定子组件11和安装座3可拆卸连接。
此外，喷洒装置中还包括有用于喷洒药液的甩盘2，甩盘2和驱动轴之间可以为可拆卸连接。具体的，甩盘2和驱动轴之间可以为卡接等快拆连接方式。
具体的，甩盘2可以为便于拆卸和维修的分体式结构。作为一种可选的结构方式，甩盘2可以包括上甩盘和下甩盘，上甩盘和下甩盘同心设置，且上甩盘和下甩盘之间形成用于甩出药液的通道。此时，药液可以进入上甩盘与下甩盘之间的间隙中，并由通道喷洒至甩盘的四周。其中，为了避免药液直接从上甩盘的周缘甩出，上甩盘的周缘可以设置有挡水圈。
可选的，上甩盘21和下甩盘22设置有导水槽。这样，导水槽能够在上甩盘21与下甩盘22的间隙中对药液形成导向，使药液沿着导水槽的路径向外洒出，提高喷洒装置在喷洒药液时的覆盖均匀性。
具体的，为了让药液向着甩盘2的四周喷洒，导水槽可以为由甩盘2的中心至甩盘2的外缘呈放射状排列的弧形槽。当甩盘2旋转时，药液即可沿着弧形的导水槽呈离心式的喷洒至甩盘2的四周，药液具有较好的散布以及覆盖范围。
其中，为了对药液的喷洒过程进行进一步优化，导水槽的弧线通常可以为阿基米德螺线。这样甩盘2匀速旋转时，药液也会均匀的随甩盘2的旋转而洒出，覆盖较为均匀。
本实施例中，喷洒装置包括具有可绕自身轴线旋转的驱动轴的驱动机构和设置在驱动轴的底部的甩盘，甩盘用于在驱动轴的旋转带动下转动并喷洒药液，驱动机构包括定子组件、转子组件和外壳组件，外壳组件包括第一外壳件和第二外壳件，第一外壳件和定子组件连接，转子组件与第二外壳件连接，且第一外壳件与第二外壳件卡合连接，第二外壳件的底部侧方设置有与甩盘内部连通的进水通道。这样喷洒装置能够方便的进行拆卸，且结构简单，与药液的隔离性较好。
在前述实施例一的基础上，本发明还提供一种无人飞行器。本实施例提供的无人飞行器，具体可以包括机体和如前述实施例一所述的喷洒装置。其中，喷洒装置的结构、工作原理及效果均已在前述实施例一中进行了详细说明，此处不再赘述。
具体的，无人飞行器的机体可以包括机身和机臂等，喷洒装置通常设置在机身的下方，且喷洒装置的数量可以为一个或多个，以满足不同的喷洒需要。
本实施例中，无人飞行器包括机体和喷洒装置；其中，喷洒装置包括具有可绕自身轴线旋转的驱动轴的驱动机构和设置在驱动轴的底部的甩盘，甩盘用于在驱动轴的旋转带动下转动并喷洒药液，驱动机构包括定子组件、转子组件和外壳组件，外壳组件包括第一外壳件和第二外壳件，第一外壳件和定子组件连接，转子组件与第二外壳件连接，且第一外壳件与第二外壳件卡合连接，第二外壳件的底部侧方设置有与甩盘内部连通的进水通道。这样喷洒装置能够方便的进行拆卸，且结构简单，与药液的隔离性较好。
最后应说明的是：以上各实施例仅用以说明本发明的技术方案，而非对其限制；尽管参照前述各实施例对本发明进行了详细的说明，本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分或者全部技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本发明各实施例技术方案的范围。
