图1示例了本申请实施例提供的风路组件的结构示意图，图10示例了本申请实施例提供的风道部件的爆炸结构示意图，如图1和图10所示，风路组件包括风道部件20、送风管部件60和回风管部件70，风道部件20设置于箱胆本体10的间室内，风道部件20的内部形成有容纳腔25，容纳腔25内设置有蒸发器部件40，风道部件20形成有与容纳腔25连通的第一回风口57和第一送风口(未示出)。送风管部件60与第一送风口连通，回风管部件70与第一回风口57连通。
根据本申请实施例的风路组件，通过将蒸发器部件40设置于风道部件20的内部，有效利用了风道部件20内部的无效空间，提高了制冷设备的容积率。风道部件20与送风管部件60构成的风路系统，最大化的缩短了风循环路径，提高了制冷效率。在总装阶段时，只需将风道部件20设置于箱胆本体10的间室内，无需单独安装蒸发器，简化了风道部件20的安装步骤，提高了生产效率。
可以理解的是，如图7所示，箱胆本体10的一侧形成有与间室连通的第一开口，第一回风口57形成于风道部件20的顶部靠近第一开口的一侧，第一送风口形成于风道部件20的顶部远离第一开口的一侧。第一开口为制冷设备的物品取出口，第一开口位于靠近制冷设备门体的一侧。
可以理解的是，图2示例了本申请实施例提供的送风管部件与回风管部件的结构示意图，如图1和图2所示，送风管部件60与回风管部件70均位于箱胆本体10顶部的外侧，将送风管部件60与回风管部件70设置于箱胆本体10顶部的外侧，减小了送风管部件60、回风管部件70与冷藏室之间的距离，缩短了风路系统的循环路径，提高了制冷效率。
箱胆本体10的顶部设置有多个通孔，送风管部件60设置于风道部件20的顶部远离第一开口的一侧，送风管部件60穿过对应的通孔与对应的间室以及第一送风口连通。回风管部件70设置于风道部件20的顶部靠近第一开口的一侧，回风管部件70穿过对应的通孔与对应的间室以及第一回风口57连通。由于送风管部件60与回风管部件70为两个独立设置的部件，在发泡过程中，发泡料可将送风管部件60与回风管部件70完全隔离，避免冷热交替所带来的结霜风险。
可以理解的是，如图1和图2所示，送风管部件60靠近回风管部件70的一侧设置有定位销，回风管部件70靠近送风管部件60的一侧设置有 定位孔53，定位销插入于对应的定位孔53，实现了送风管部件60与回风管部件70之间的连接。送风管部件60与回风管部件70可以线下一体化装配后再与风道部件20装配，也可以分开独立与风道部件20进行装配。
可以理解的是，箱胆组件包括两个箱胆本体10，两个箱胆本体10呈上下分布，每个箱胆本体10的内部具有一个间室，两个间室呈上下分布，风道部件20设置于下部箱胆本体10的间室内。上部的间室为冷藏间室，冷藏间室与下部的间室为两个独立的间室。风道部件20将下部的间室分隔为冷冻间室和变温间室，为了满足用户不同的需求，还可在冷藏间室内设置冰温间室。
可以理解的是，图3示例了本申请实施例提供的回风管部件的仰视结构示意图，图4示例了本申请实施例提供的回风管部件的爆炸结构示意图，如图3和图4所示，回风管部件70包括回风管，上部形成有第一冷藏回风口71，第一冷藏回风口71适于与上方的冷藏间室的回风口连通。回风管的下部形成有第一变温回风口72、第二变温回风口73和第二冷藏回风口74，第一冷藏回风口71与第二冷藏回风口74连通，第一变温回风口72与第二变温回风口73连通；第一变温回风口72以及第二冷藏回风口74均与第一回风口57连通。第二变温回风口73适于与变温间室连通。由于冷藏间室与变温间室共用一个回风管，这种一体化设计简化了回风管路的结构，降低了生产成本，提高了回风管路的可靠性。回风管部件70位于下部间室与上部间室之间的发泡层，回风管部件70无论到冷藏间室还是变温间室的距离都是最短的，有效减小了回风管路径的长度。
还可以理解的是，第二变温回风口73间隔设置有多个导风片，导风片朝向第一变温回风口72倾斜，这样使得变温室内的空气进入第二变温回风口73之后，在导风片的作用下，空气直接流向第一变温回风口72，减小了空气的流动路径和风阻，进一步提高了制冷效率。
可以理解的是，如图3和图4所示，回风管包括回风管上壳体75和回风管下壳体76，第一冷藏回风口71形成于回风管上壳体75的上部，第一冷藏回风口71为矩形风口。第一变温回风口72和第二冷藏回风口74形成于回风管上壳体75的下部，第一变温回风口72和第二冷藏回风口74均为矩形风口，第一变温回风口72适于将变温间室内的空气输送至第一回风口57。冷藏间室内的空气先进入第一冷藏回风口71，再通过第二冷藏回风口74输送至第一回风口57，冷藏间室内的空气和变温间室内的空气最终通过第一回风口57进入到容纳腔25内与蒸发器部件进行热交换。
回风管下壳体76设置于回风管上壳体75的下方，第二变温回风口73形成于回风管下壳体76的下部，第二变温回风口73位于变温间室的上方。回风管下壳体76与回风管上壳体75围成第二流道，第二流道分别与第一变温回风口72以及第二变温回风口73连通。当然，第一变温回风口72与第二变温回风口73的连通方式并不限定于此，也可将第一变温回风口72 与第二变温回风口73直接连通。回风管下壳体76与回风管上壳体75的下部通过卡扣连接，以方便回风管的安装和拆卸。当然，回风管下壳体76与回风管上壳体75的连接方式并不限定于此，也可采用螺栓或者一体成型的连接方式。
可以理解的是，图13示例了本申请实施例提供的箱胆本体的主视结构示意图，图14示例了图13中剖面线A-A处的剖面结构示意图，图15示例了图13中剖面线C-C处的剖面结构示意图，图16示例了图15中剖面线B-B处的剖面结构示意图，如图13至图16所示，送风管部件60分别与冷冻间室送风口68、冷藏间室送风口、冰温间室送风口以及变温间室送风口69连通，由于将给各个间室输送冷风的管路集成于送风管，这样的一体化设计简化了送风管路的结构，减低了生产成本。
可以理解的是，图5示例了本申请实施例提供的送风管部件的结构示意图，图6示例了本申请实施例提供的送风管部件的爆炸结构示意图，如图5和图6所示，送风管部件60包括送风管、第一风门64和第二风门65，送风管内部形成有第一流道，送风管形成有与第一流道连通的进风口、第二送风口61、第三送风口62和第四送风口，其中，进风口与第一送风口连通，温度降低后的冷空气依次通过第一送风口、进风口进入到第一流道内，再通过第二送风口61、第三送风口62和第四送风口将冷空气送入对应的间室内。第一风门64设置于第二送风口61，第一风门64的进风端口与第二送风口61连通，第二风门65设置于第三送风口62，第二风门65的进风端口与第三送风口62连通。
第一风门64为双风门，第一风门64的第一出风端口与冷藏室的出风口连通，第一风门64的第二出风端口与冰温间室送风口连通，第一风门64适于控制分别进入冷藏间室以及冰温间室的冷量。第二风门65为单风门，第二风门65的出风口与变温间室送风口69连通。第二风门65适于控制进入变温间室的冷量。第四送风口与冷冻间室送风口68连通。当然，第一风门64的类型并不限定于此，也可以为单风门或者三风门，具体根据冷藏间室的温区设定需求进行确定。
可以理解的是，送风管包括第一送风管壳体66和第二送风管壳体67，第一送风管壳体66与第二送风管壳体67围成第一流道，第一送风管壳体66和第二送风管壳体67通过卡扣连接，以方便送风管的安装和拆卸。第二送风口61通过第一送风管壳体66上的开口和第二送风管壳体67上的开口拼接构成。当然第二送风口61也可单独设置于第一送风管壳体66或者第二送风管壳体67，同样地进风口、第三送风口62以及第四送风口，可以通过第一送风管壳体66上的开口和第二送风管壳体67上的开口拼接构成，也可单独设置第一送风管壳体66或者第二送风管壳体67。
风路组件的工作原理：
如图1至图6所示，空气循环过程中，冷藏间室内的空气先进入第一 冷藏回风口71，再通过第二冷藏回风口74进入第一回风口57；变温间室内的空气依次通过第二变温回风口73、第一变温回风口72进入第一回风口57。冷藏间室内的空气和变温间室内的空气最终通过第一回风口57进入到容纳腔25内与蒸发器部件进行热交换。进行热量交换之后空气的温度进一步降低成为冷空气，如图5所示，冷空气(实心宽箭头)分别在风机31作用下通过第一送风口进入到第一流道内，此时冷空气分为四路；其中，第一路冷空气(空心虚线宽箭头)通过第四送风口进入到冷冻间室内进行降温；第二路冷空气(虚线窄箭头)进入到第一风门64内，最终通过第一风门64的第一出风端口进入到冷藏室进行降温；第三路冷空气(实线窄箭头)进入到第一风门64内，最终通过第一风门64的第二出风端口进入到冰温间室进行降温；第四路冷空气(实线空心宽箭头)进入到第二风门65最终进入到变温间室内进行降温。
图7示例了本申请实施例提供的箱胆本体与风道部件的装配关系示意图，如图7和图10所示，根据本申请实施例的风道部件20，通过将蒸发器部件40设置于风道部件20的内部，在总装阶段时，只需将风道部件20设置于箱胆本体10的间室内，再将蒸发器部件40的管路与制冷系统的管路进行焊接，无需设置单独安装蒸发器步骤的岗位，降低了人力成本，简化了风道部件的安装步骤，提高了生产效率。
可以理解的是，风道部件20设置于箱胆本体10内部的间室内，风道部件20将间室分隔成第一间室14和第二间室15，风道部件20包括至少两个可拆卸连接的盖板，风道部件20的内部形成有容纳腔25，蒸发器部件40设置于容纳腔25内。
根据本申请实施例的风道部件20，通过将蒸发器部件40设置于容纳腔25内，拆卸蒸发器部件40时只需要将盖板拆卸下来，便可拆卸蒸发器部件40，简化了蒸发器部件40的拆卸步骤，方便对蒸发器部件40进行维护。
可以理解的是，风道部件20设置于箱胆本体10的间室内，风道部件20朝向箱胆本体10内壁的侧边形成有容胶槽26，箱胆本体10的内壁形成有与容胶槽26连通的通孔16，容胶槽26内填充有分别与内壁以及风道部件20的侧边连接的发泡料。
可以理解的是，如图10所示，风道部件20包括第一盖板21、第二盖板22、真空隔热板23和真空隔热板盖板24，第二盖板22与第一盖板21相对设置，真空隔热板23设置于第二盖板22与第一盖板21之间。真空隔热板盖板24设置于真空隔热板23背离第二盖板22的一侧，真空隔热板盖板24的形状与第一盖板21的形状以及第二盖板22的形状相匹配，真空隔热板盖板24的面积与第二盖板22的面积均大于真空隔热板23的面积，以确保真空隔热板盖板24与第二盖板22将真空隔热板23夹持于中间时可将真空隔热板23完全包裹。容纳腔25形成于真空隔热板盖板24与 第一盖板21之间，即容纳腔25由真空隔热板盖板24与第一盖板21围成，容纳腔25用于安装风机部件、蒸发器部件40以及风机安装板33。真空隔热板盖板24分别与第一盖板21以及第二盖板22通过螺钉连接，也可通过卡扣连接，还可通过其他可拆卸连接方式连接。容胶槽26形成于真空隔热板盖板24的后侧边27和下侧边28，容胶槽26的位置与定位槽13的位置对应。第一回风口57和第一送风口形成于真空隔热板盖板24的顶部。
在相关技术中，蒸发器部件40位于冷冻风道组件的后侧，拆卸蒸发器部件40时，需要先取出两侧的冷冻抽屉，再拆掉冷冻箱胆中隔板的螺钉，再取下中隔板，再拆掉冷冻风道组件的螺钉，再取下冷冻风道组件，最后拆掉蒸发器。由于蒸发器的拆卸步骤较多，蒸发器维护难度较大。
通过将蒸发器部件40设置于容纳腔25中，不仅简化了制冷设备的安装步骤，还简化了蒸发器部件40的拆卸步骤。拆卸蒸发器部件40时，先取出冷冻风道单侧的冷冻抽屉，再拆卸第一盖板21或者第二盖板22的螺钉，再取下第一盖板21或者第二盖板22，最后拆掉蒸发器部件40。相较于上述相关技术中蒸发器的拆卸方式，将蒸发器部件40设置于容纳腔25中，不仅提高了制冷设备的容量，简化了制冷设备的安装步骤，还简化了蒸发器部件40的安装步骤。
可以理解的是，风道部件20竖直设置于间室内，第一盖板21位于风道部件20朝向第一间室14的一侧，第二盖板22位于风道部件20背离第一间室14的一侧。
图8示例了本申请实施例提供的箱胆本体的立体结构示意图，图9示例了本申请实施例提供的箱胆本体与风道部件处于分离状态下的结构示意图，如图7至图10所示，本申请还提供一种箱胆组件包括箱胆本体10，箱胆本体10内部形成有间室，箱胆本体10的一侧形成有与间室连通的第一开口，箱胆本体10的内壁形成有通孔16。风道部件20设置于间室内，风道部件20朝向内壁的侧边与箱胆本体10的内壁围成空腔，空腔与通孔16连通，空腔内填充有分别与内壁以及风道部件20的侧边连接的发泡料。
根据本申请实施例的箱胆组件，发泡前将风道部件20安装于箱胆本体10的间室内，通过在风道部件20朝向箱胆本体10内壁的侧边与箱胆本体10的内壁之间围成空腔，发泡时发泡料会通过通孔16流入空腔内，由于发泡时发泡料是流动的液体，即使箱胆本体10或者风道部件20发生形变，发泡料也能将箱胆本体10与风道部件20之间的间隙进行有效密封，避免了冷冻风道漏冷，增强了制冷效果，有效防止风道结冰。
可以理解的是，如图9所示，空腔包括容胶槽26，容胶槽26形成于风道部件20朝向内壁的侧边，当箱胆本体10的侧壁为平面时，容胶槽26为空腔的全部。风道部件20安装到位后，风道部件20朝向内壁的侧边与箱胆本体10的内壁抵接，内壁的通孔16与容胶槽26连通，发泡料可通过通孔16进入到容胶槽26中，并将整个容胶槽26填充，实现风道部件20 与箱胆本体10之间的密封。
箱胆本体10的侧壁形成有定位机构(即定位槽13)时，容胶槽26与定位机构连通，此时空腔由容胶槽26与定位机构构成。当风道部件20安装到位后，风道部件20朝向内壁的侧边与定位结构卡接配合，内壁的通孔16与容胶槽26以及定位机构连通，发泡料通过通孔16进入到容胶槽26，除了将整个容胶槽26填充之外还会填充定位机构。定位机构可以是凹槽，也可是定位凸楞或者其他定位机构。
可以理解的是，如图7所示，风道部件20竖直设置于间室内，风道部件20将间室分隔成第一间室14和第二间室15，其中第一间室14为图1中左侧的间室，第一间室14为冷冻间室，第二间室15为图1中右侧的间室，第二间室15为变温间室。第一间室14的容量与第二间室15的容量可以相同，也可不同，具体根据实际需要确定第一间室14和第二间室15的容量。当然风道部件20的设置方式并不限定于竖直设置，也可以水平设置，此时两个间室在竖直方向上分布。
相关技术中蒸发器和冷冻风道设置于箱胆的后壁11，这样的布置方式占用了冷冻间室内的空间，减小了冷冻间室在前后方向的深度。本申请实施例的箱胆组件，通过将风道部件20竖直设置于间室内，增加了冷冻间室的前后方向的空间，提高了制冷设备的空间利用率。同时，还方便蒸发器部件的安装和拆卸。
容胶槽26形成于风道部件20的后侧边27和下侧边28，后侧边27的容胶槽26与下侧边28的容胶槽26连通，当然后侧边27的容胶槽26与下侧边28的容胶槽26也可相互独立，即后侧边27的容胶槽26与下侧边28的容胶槽26不连通。当然，容胶槽26的设置位置并不限定于风道部件20的后侧边27和下侧边28，也可以在风道部件20的上侧边设置容胶槽26，上侧边容胶槽26内的发泡料与箱胆本体10的顶壁连接。
这里需要说明的是，本申请实施例中的前后方向指用户打开或关闭制冷设备门体时，用户面对的方向为后方，用户背对的方向为前方，用户的左手边为左侧，右手边为右侧。
可以理解的是，如图8所示，空腔还包括定位槽13，定位槽13形成于箱胆本体10的内壁，箱胆本体10的后壁11的定位槽13沿着箱胆本体10的高度方向延伸，箱胆本体10的底壁12的定位槽13沿着前后方向延伸。风道部件20朝向内壁的侧边卡接于定位槽13内，定位槽13与容胶槽26连通。发泡料通过通孔16进入到容胶槽26内，将整个容胶槽26和定位槽13填充。发泡料固化后可将空腔填充密封，从而实现风道部件20与箱胆本体10之间的密封，同时发泡料还可对风道部件20起到一定的固定作用。
可以理解的是，如图9所示，定位槽13形成于箱胆本体10的后壁11和底壁12，后壁11的定位槽13与底壁12的定位槽13连通，当然，后壁 11的定位槽13与底壁12的定位槽13也可相对独立设置，即后壁11的定位槽13与底壁12的定位槽13不连通。后侧边27卡接于后壁11的定位槽13内，下侧边28卡接于底壁12的定位槽13内。当然，在定位槽13也可形成于箱胆本体10的顶壁，此时，风道部件20的上侧卡接于顶壁的定位槽13中。定位槽13的宽度大于或等于风道部件20的宽度。
可以理解的是，通孔16沿着定位槽13的长度方向间隔布置，以使得发泡过程中发泡料可以进入容胶槽26的每个区域，提高风道部件20与箱胆本体10之间的密封性，避免了冷冻风道漏冷，降低了制冷设备的能耗。通孔16可以为圆形孔或者矩形孔，此时多个通孔16沿着定位槽13的长度方向间隔设置，当然，通孔还可以为条形通孔，此时通孔16沿着定位槽13的长度方向延伸。
在相关技术中，需要在箱体发泡后总装段安装，先安装接水盘50然后安装蒸发器组件，蒸发器焊接完成后，最后在安装风道组件，总装段工序较多并且复杂，工序越多越影响生产效率。
可以理解的是，如图10所示，风道部件20的内部形成有容纳腔25，蒸发器部件40设置于容纳腔25内。由于蒸发器部件40是预先设置于风道部件20内部，发泡前只需将风道部件20安装于箱胆本体10的间室内，总装段只需将蒸发器部件40的管路与制冷系统的管路进行焊接，简化了制冷设备的安装步骤，提高了生产效率；由于减少了装配蒸发器和接水盘50的工人，降低了人工成本。
可以理解的是，风道部件20上形成有与蒸发器部件40的焊接位对应的焊接窗口34，设置焊接窗口34可方便工作人员对蒸发器部件40的管路进行焊接，减少焊接时间，提高生产效率。
可以理解的是，如图10所示，焊接窗口34盖合有盖体，盖体与风道部件20可拆卸连接。盖体与风道部件20可以通过卡扣连接，也可通过螺钉连接。在对蒸发器进行焊接时打开盖体，焊接结束后将盖体盖合于焊接窗口34。
可以理解的是，风道部件20竖直设置于间室内，焊接窗口34位于风道部件20靠近第一开口的边缘。由于焊接窗口34靠近第一开口，工作人员可通过焊接窗口34进行焊接时操作更方便，使工作人员焊接时身体处于舒服的状态，减小了工作人员身体的疲劳度，提高了工作效率。
可以理解的是，相关技术中竖置制冷系统由于回风口的位置高于底部抽屉，往往易造成冷冻室底部抽屉的温度偏高，温度不达标，影响冷冻效果。本申请的箱胆组件通过在风道部件20的底部设置与容纳腔25连通的冷冻回风口30，冷风从出风口出来后，环绕底部的抽屉后，通过冷冻回风口30回到蒸发器部件40中，有效解决竖置制冷系统底部抽屉温度不达标的问题。
可以理解的是，风机部件设置于容纳腔25内，风机部件还包括风机31 和蜗壳32。蜗壳32位于蒸发器部件40的上方。蜗壳32的内部中空，蜗壳32形成有进气口和出气口。风机31设置于蜗壳32内，风机31用于驱动气流通过冷冻回风口30进入到容纳腔25内并与蒸发器接触，气流与蒸发器接触后，气温进一步降低，最后通过出风口排出。
可以理解的是，为了方便风机31的安装，容纳腔25内还设置有风机安装盖板33，风机安装盖板33位于蒸发器与真空隔热板盖板24之间，风机安装盖板33与真空隔热板盖板24通过螺钉连接，蜗壳32通过螺钉固定于风机安装盖板33的上部。
可以理解的是，图11示例了本申请实施例提供的风道部件的剖面结构示意图，图12示例了本申请实施例提供的接水盘的结构示意图，如图11和图12所示，箱胆组件还包括接水盘50，接水盘50设置于容纳腔25内，接水盘50位于蒸发器部件40的下方。接水盘50用于容纳蒸发器部件40产生的冷凝水，冷凝水产生后在重力的作用下自动流入接水盘50。
可以理解的是，接水盘50的下部形成有与冷冻回风口30连通的接水盘回风口51。
可以理解的是，如图12所示，接水盘50包括连接部54和接水盘主体55，连接部54的顶部开口，连接部54套设于蒸发器部件40的底部。接水盘主体55设置于连接部54的下方，接水盘主体55与连接部54连接，接水盘主体55与连接部54一体成型。当然，接水盘主体55与连接部54也可为两个独立的部件，接水盘主体55与连接部54通过螺钉或者卡扣连接。接水盘主体55的内部形成有与连接部54内部连通的容水槽，接水盘回风口51形成于接水盘主体55的侧壁。连接部54既能将蒸发器部件40产生的水引导至容水槽，又能将通过接水盘回风口51进入的气流引导蒸发器部件40。
间室底部的冷风通过冷冻回风口30进入到容纳腔25中，再通过接水盘回风口51进入到接水盘50中，最后通过连接部54的顶部进入到蒸发器部件40中进行热量交换。由于无需单独设置风道，有效简化了箱胆组件的结构，降低了生产成本。
可以理解的是，如图12所示，接水盘主体55的底部形成有与容水槽连通的排水端口52，排水端口52用于将容水槽中的冷凝水排出。接水盘主体55的底面朝向排水端口52向下倾斜，将接水盘主体55的底面向下倾斜可使得容水槽中的水尽快排出，避免冷凝水结冰。接水盘主体55呈V字型，当然也可以呈C字型。
可以理解的是，真空隔热板盖板24朝向第一盖板21一侧的下部形成有支撑部，接水盘主体55的底部抵接于支撑部的顶部。连接部54的宽度大于接水盘主体55的宽度，由于接水盘主体55的宽度较窄，这就使得接水盘主体55与第一盖板21之间形成夹层风道56，夹层风道56分别与冷冻回风口30以及接水盘回风口51连通。
可以理解的是，风道部件20的后侧边27形成有定位孔53，排水端口52穿设于定位孔53，排水端口52与排水管插接连接。当然，排水端口52与排水管的连接方式并不限定于此，也可将排水管穿过定位孔53之后引入容纳腔25内再与排水端口52连接。
可以理解的是，焊接窗口34位于第一盖板21靠近第一开口的边缘，冷冻回风口30位于第二盖板22的下部。此时第一间室14为冷冻间室，第二间室15为变温间室。当然，冷冻回风口30的位置并不限定于此，也可将冷冻回风口30设置于第二盖板22，此时，第一间室14为变温间室，第二间室15为冷冻间室。
可以理解的是，风道部件20的侧边通过多个连接件与箱胆本体10的内壁可拆卸连接。
可以理解的是，为了对风道部件20进行有效固定，真空隔热板盖板24的侧边与箱胆本体10的内壁通过多个旋钮连接，使用旋钮可方便将真空隔热盖板35的侧边与箱胆本体10的内壁进行快速连接。由于真空隔热盖板35的侧边与箱胆本体10的内壁除了通过发泡料连接之外，还通过旋钮连接，采用两种方式共同配合对风道部件20进行固定，有效提高了风道部件20的稳定性。当然，也可采用螺钉或者卡扣将真空隔热盖板35的侧边与箱胆本体10的内壁进行连接。
本申请还提供一种制冷设备，包括壳体、箱胆本体和上述任意一项实施例所述的风路组件，箱胆本体设置于壳体内，送风管部件与回风管部件设置于壳体与箱胆本体之间。
以上实施方式仅用于说明本申请，而非对本申请的限制。尽管参照实施例对本申请进行了详细说明，本领域的普通技术人员应当理解，对本申请的技术方案进行各种组合、修改或者等同替换，都不脱离本申请技术方案的精神和范围，均应涵盖在本申请的权利要求范围中。
