下面结合附图并参考具体实施方式描述本公开：
本公开实施方式所提供的一种天花机，旨在至少能够在一定程度上解决水泵安装在底盘上，导致零部件多，成本高，且装配效率低的技术问题。
图1为依据本公开一些实施方式的天花机的结构示意图，图2为图1中天花机的爆炸图，图3为图1中天花机的水泵组件布置示意图，图4为图3的俯视图。结合图1、图2、图3和图4，在一些实施方式中天花机包括：壳体10、支架20、换热器30、接水盘40及水泵组件50。壳体10开设有进风口101和出风口102。支架20固定于壳体10内。换热器30设于壳体10内，并固定于支架20上，换热器30设于进风口和出风口之间。接水盘40设于壳体10内，并位于换热器30下方。水泵组件50设于壳体10内，并固定于支架20上，水泵组件50的进水口与接水盘40连通。
换热器30可以为蒸发器。
壳体10可安装在墙体或天花板上。
支架20可拆卸式地固定于壳体10内，也可非可拆卸式地固定于壳体10内。为了便于换热器30的检修。在一些实施方式中，支架20可拆卸式地固定于壳体10内。
水泵组件50可拆卸式地固定于支架20上，也可非可拆卸式地固定于壳体10上。为了便于水泵组件50的检修。在一些实施方式中，水泵组件50可拆卸式地固定于支架20上。
在现有技术中，将水泵安装在底盘上时，需要在底盘的泡沫上嵌入钣金件。在钣金件上安装水泵，导致零部件多，成本高。而且安装过程存在盲区，导致装配工艺复杂，装配工 艺设计所需时间较长，装配效率低。
本公开的一些实施方式中，壳体10可以开设有进风口101和出风口102。支架20可以固定于壳体10内，换热器30可以设于壳体10内，并且换热器30可以固定于支架20上，且换热器30位于在进风口101与出风口102之间由壳体10自身结构与容置在内的部件形成的风道之中。空气由进风口101进入壳体10内，流经风道的空气与换热器30热交换后，从出风口102排出。接水盘40可以设于壳体10内并位于换热器30下方，由此换热器30热交换后在外壳上产生的冷凝水可以落入接水盘40内，避免冷凝水流出，提高用户体验。水泵组件50可以设于壳体10内，并可以固定于支架20上。水泵组件50的进水口可以与接水盘40连通。可以直接将水泵组件50安装在支架20上，即可完成水泵组件50的装配，使得装配便捷，提高了装配效率。在本公开一些实施方式中，支架20不仅可以支撑换热器30，还可以支撑水泵组件50，从而减少零部件，降低成本。当接水盘40上有冷凝水时，还可以通过水泵组件50将接水盘40上的冷凝水排出，以避免接水盘40上的冷凝水溢出，提高用户体验。
结合图1和图2，在一些实施方式中，为了实现对进入壳体内的空气进行充分换热，换热器30可以为环状。在空气由进风口101进入壳体10内，并流经换热器30周围的风道时，与环状的换热器30进行热交换后从出风口102排出。
结合图1、图2和图3，在一些实施方式中，为了便于换热器30的冷媒进出，以与空气持续进行热交换，换热器30可以开设有缺口。换热器30的冷媒进管和冷媒出管均可设置在缺口处。
结合图3，在一些实施方式中，支架20可以设于换热器30的缺口之间，以充分利用壳体10内的空间，便于壳体10内其余设备的布置。支架20可以与换热器30连接以支撑换热器30，从而保证换热器30在壳体10内安装的稳定性。
结合图3，在一些实施方式中，为了便于支架20和换热器30的连接，支架20和换热器30中的一者可以设有卡扣301，另一者可以开设有卡槽201。卡扣301可以卡设于卡槽201内，以实现支架20与换热器30的预连接。也就是说，在将换热器30安装到支架20上时，将卡扣301卡设于卡槽201内，实现支架20与换热器30的预连接。此外还可以通过联结件202联结卡扣301与卡槽201，以紧固支架20和换热器30的连接。在一些实施方式中，联结件202可以为螺钉。
，换热器30可以设有卡扣301，支架20可以开设有卡槽201，卡扣301卡设于卡槽201内。当然，在其它实施方式中，支架20可以设有卡扣301，换热器30可以开设有卡槽201，卡扣301可以卡设于卡槽201内。但是，由于换热器30内需设置冷媒进管和冷媒出管，为了换热器30的结构完整性和内部空间最大化。在一些实施方式中，换热器30设有卡扣301，支架20开设有卡槽201。
图5为图1中天花机的水泵组件在支架上的安装示意图，图6为图1中天花机的水泵组件的结构示意图。结合图5和图6，在一些实施方式中，支架20的两侧可以设有第三翻边204，在第三翻边204开设卡槽201。这样能够充分利用支架20本身结构，不需要增加零部件，降低了成本。
结合图5，在一些实施方式中，由于支架20和壳体10的内壁之间有间距，形成了容置空间。而为了进一步地利用壳体10内的空间，支架20朝向水泵组件50的端部的中部向壳体10的方向翻折以形成第一翻边203，这样避免了第一翻边203侵占风机60的安装空间。通过第一翻边203与水泵组件50连接以支撑水泵组件50，能够充分利用支架20本身结构，不需要增加零部件，降低了成本。同时，水泵组件50设于容置空间内，便于水泵组件50的安装，同时，充分利用了壳体10内的空间。
结合图5和图6，在一些实施方式中，水泵组件50可以包括固定架501和水泵502。固定架501可以包括与支架20连接的连接部5011和与连接部5011连接的支撑部5012。由此可以通过支架20支撑连接部5011，通过连接部5011支撑支撑部5012。在一些实施方式中，连接部5011和支撑部5012可一体成型，这样能够保证固定架501的结构强度，以保证支撑 水泵502的稳定性。水泵502可以设于支撑部5012上，通过支撑部5012支撑水泵502，以保证水泵502安装的稳定性。为了抽取接水盘40内的冷凝水，水泵502的进水口与接水盘40连通，以将接水盘40内的冷凝水抽出，使得能够避免冷凝水由接水盘40溢出，提高用户体验。
结合图5和图6，在一些实施方式中，支撑部5012上可以设有第二翻边5013。水泵502可以设于第二翻边5013上，以通过第二翻边5013支撑水泵502，使得能够充分利用支撑部5012本身的结构，不需要再增加零部件，以降低成本。
图7为图6中水泵组件的第一缓冲件的结构示意图。结合图5、图6和图7，在一些实施方式中，水泵502在运行过程中，会发生震动。因此，为了降低震动，也为了降低噪声，水泵组件50还可以包括：第一缓冲件503、第二缓冲件504和锁紧件505。第一缓冲件503可以设于连接部5011和支架20之间。第二缓冲件504可以设于连接部5011背离第一缓冲件503的端部。锁紧件505依次穿过支架20、第一缓冲件503、连接部5011后与第二缓冲件504连接。通过锁紧件505将支架20、第一缓冲件503、连接部5011与第二缓冲件504连接为一体。在一些实施方式中，第一缓冲件503和第二缓冲件504的材质可以为橡胶。
在一些实施方式中，当水泵502运行时，水泵502所产生的震动会从支撑部5012传递给连接部5011。此时，一方面，第一缓冲件503进行缓冲减震，以减少从连接部5011传递给支架20的震动。另一方面，锁紧件505的一端与连接部5011之间设有第二缓冲件504，因此通过第二缓冲件504减少了连接部5011传递给锁紧件505的震动，进而，减少了锁紧件505传递给支架20的震动。这样不仅减震效果好，还降低了噪声。
在一些实施方式中，第一缓冲件503、第二缓冲件504和锁紧件505的数目均可以为一个或多个。也就是说，第一缓冲件503、第二缓冲件504和锁紧件505可以是一一对应的。在第一缓冲件503、第二缓冲件504和锁紧件505的数目为一个时，锁紧件505的截面形状为非圆形，相应地在连接部5011上开设的供锁紧件505穿过的通孔的截面形状与第二锁紧件505的截面形状相匹配，由此通过锁紧件505和通孔相配合，以实现对连接部5011的位置的限定，避免连接部5011在支架20上发生转动。在第一缓冲件503、第二缓冲件504和锁紧件505的数目为多个时，锁紧件505的截面形状可以为圆形。通过多个锁紧件505可以实现对连接部5011的位置的限定，避免连接部5011在支架20上发生转动。而为了保证减震效果。在一些实施方式中，第一缓冲件503、第二缓冲件504和锁紧件505的数目可以为多个。
结合图5、图6和图7，在一些实施方式中，为了保证支架20与连接部5011连接牢靠，锁紧件505还可以包括：锁紧部5051和紧固部5052。锁紧部5051可以设于第二缓冲件504背离连接部5011的端面上。紧固部5052可以依次穿过支架20、第一缓冲件503、连接部5011、第二缓冲件504后与锁紧部5051连接。在一些实施方式中，锁紧部5051可以为螺母，紧固部5052可以为螺栓。
在一些实施方式中，当要将连接部5011安装在支架20上时，紧固部5052可以依次穿过支架20、第一缓冲件503、连接部5011、第二缓冲件504后与锁紧部5051连接，以实现连接部5011与支架20的连接，并保证连接部5011与支架20连接牢靠。当水泵502运行时，水泵502所产生的震动会从支撑部5012传递给连接部5011。此时，由于锁紧部5051设于第二缓冲件504背离连接部5011的端面上，通过第二缓冲件504减少连接部5011传递给锁紧部5051的震动，进而，能够减少锁紧部5051传递给由紧固部5052和紧固部5052传递给支架20的震动。这样不仅减震效果好，还降低了噪声。
结合图7，在一些实施方式中，为了便于锁紧部5051的安装，第二缓冲件504背离连接部5011的端面可以开设有第一凹槽。锁紧部5051可以设于第一凹槽内，以使锁紧部5051的顶部与第二缓冲件504的顶部平齐，保证美观。同时，通过第一凹槽可以容纳并固持住锁紧部5051，使得当旋拧紧固部5052以与锁紧部5051连接时，锁紧部5051不会随之一起转动。这样只需操作紧固部5052即可实现紧固部5052与锁紧部5051的连接。
在一些实施方式中，为了保证减震效果，第二缓冲件504可以为至少两个。为了降低 零部件数量，至少两个第二缓冲件504中每相邻的两个第二缓冲件相互连接。也就是说，仅通过一套模具就可完成制备，这样减少了零部件数量，降低了成本。为了在保证缓冲效果的同时，也可以降低成本。在一些实施方式中，第二缓冲件504的数目可以为三个，且三个第二缓冲件504成三角形布置。三角形布置具有稳定性，保证了每相邻的两个第二缓冲件504之间连接的稳定性。
结合图5、图6和图7，在一些实施方式中，为了避免水泵502的振动导致第一缓冲件503或第二缓冲件504跑偏，影响减震效果。水泵组件50还可以包括连接件506。连接件506的一端与第一缓冲件503连接，另一端穿过连接部5011与第二缓冲件504连接。通过连接件506可以将第一缓冲件503和第二缓冲件504连接为一体。连接件506穿设于供锁紧件505穿过的通孔内，这样就能够通过通孔对连接件506进行限位，从而避免与连接件506连接成一体的第一缓冲件503或第二缓冲件504跑偏，保证减震效果。而且，连接件506可以套设于锁紧件505对其减震。这样进一步地降低连接部5011传递给锁紧件505的震动，保证减震效果。在一些实施方式中，连接件506的材质为橡胶。
在一些实施方式中，连接件506可以为套筒状，以便于锁紧件505穿过连接件506与第二缓冲件505连接。连接件506的外径可以与通孔的直径相匹配。连接件506的内径可以大于或等于锁紧件505的紧固部5052的直径。也就是说，连接件506可以设于锁紧件505的紧固部5052和通孔的孔壁之间，以保证减震效果。
在一些实施方式中，连接件506可以将第一缓冲件503和第二缓冲件504连接为一体。也就是说，仅通过一套模具就可完成制备，这样减少了零部件数量，降低了成本。
在一些实施方式中，为了便于锁紧件505与第二缓冲件504连接，连接部5011上开可以设有通孔。锁紧件505可以穿过该通孔与第二缓冲件504连接。第一缓冲件503的面积和第二缓冲件504的面积可以均大于通孔的面积，以避免第一缓冲件503或第二缓冲件504进入通孔内，保证减震效果。
结合图7，在一些实施方式中，为了降低成本，第一缓冲件503可以包括第一缓冲部5031和与第一缓冲部5031连接的第二缓冲部5032。第二缓冲部5032的直径沿远离第一缓冲部5031的方向逐渐减小。同时，在锁紧件505紧固时，第二缓冲部5032能够提供缓冲区间，避免过度紧固使第一缓冲件503过度变形，从而保证了减震降噪的效果。在一些实施方式中，第二缓冲部5032的截面形状可以为圆台状。
结合图6，在一些实施方式中，为了便于水泵502将接水盘40上的冷凝水排出，水泵502上可以设有排水嘴507。水泵502的进水口抽取接水盘40上的冷凝水，再从排水嘴507排出。而为了便于将冷凝水排放至预设位置，会在排水嘴507上套设排水管509，以延长排水路径。在一些实施方式中，排水管509可以为柔性管。
结合图6，在一些实施方式中，为了保证排水管509与排水嘴507之间连接牢靠，避免排水管509与排水嘴507分离，导致冷凝水流入壳体10内，排水嘴507上可以套设有防脱件508。将排水管509套设于防脱件508上，再通过卡合件将排水管509锁紧在排水嘴507上。卡合件可以设于防脱件508和水泵502之间，使得当排水管509向远离水泵502的方向滑动时，卡合件会与防脱件508相抵接。由此，通过防脱件508抵住卡合件，能够避免排水管509与排水嘴507分离。这样保证了排水的稳定性，提高了用户体验，保证设备安全。在一些实施方式中，防脱件508为环状，卡合件可以为卡箍或卡扣。
结合图1和图2，在一些实施方式中，为了保证安全，天花机还可以包括与壳体10连接的底盘60。底盘60可以通过支架20与换热器30电连接，以实现连续接地保护人和设备不受伤害。这样不再额外需要线缆连接底盘60和换热器30，降低了成本。同时，底盘60也通过支架20支撑换热器30，以保证换热器30安装的稳定性。在一些实施方式中，支架20的材质可以为金属，如铁、钢、铝合金等。
结合图1和图2，在一些实施方式中，为了保证能将空气引入壳体10内，天花机还可以包括风机70。风机70和换热器30由内至外间隔设于壳体10内。风机70可以设于换热器 30和进风口101之间。启动风机70，风机70从进风口101处抽取空气，空气经过换热器30时，与换热器30进行热交换，热交换后的空气再通过出风口102排出。在一些实施方式中，风机可以为离心风机。
结合图1和图2，在一些实施方式中，为了便于进风和排风，天花机还包括可以面板80。面板80可以设于壳体10上，并与底盘60相对。进风口101和与出风口102开设于面板80上。启动风机70，空气依次通过进风口101、风机70、换热器30，再通过出风口102排出。
结合图1和图2，在一些实施方式中，为了防止杂物进入壳体10内，面板80上可以设有格栅801。格栅801可以遮挡进风口101。通过格栅801可以遮挡杂物，保证风机70的安全。
结合图1和图2，在一些实施方式中，为了保证出风风量，出风口102的数目可以为多个。面板80上可以设有多个可转动的导风件802。导风件802可在第一位置和第二位置之间切换。在导风件802位于第一位置时，导风件802打开出风口102。在导风件802位于第二位置时，导风件802关闭出风口102。导风件802上可以开设有多个导风孔8021，在用户需要冷风直吹时，导风件802可以位于第一位置，使得导风件802打开出风口102，与换热器30热交换后的空气直接从出风口102排出。在用户不需要冷风直吹，为了进入无风感模式时，导风件802可以位于第二位置，使得导风件802关闭出风口102，与换热器30热交换后的空气从导风孔8021排出，防止冷风直吹，提高舒适性。在一些实施方式中，导风孔8021的直径可以为2mm-5mm。
在一些实施方式中，面板80上可以设有驱动器。驱动器的驱动部与导风件802连接，以驱动导风件802进行转动，使得导风件802可在第一位置和第二位置之间切换。
结合图2，在一些实施方式中，壳体10内可以设有电控盒90。电控盒90可以与水泵502、风机70、换热器30和驱动导风件802转动的驱动器电连接，以向水泵502、风机70、换热器30和驱动导风件802转动的驱动器发送控制信号，以控制水泵502、风机70、换热器30和驱动导风件802转动的驱动器进行相应的动作。
结合图2，在一些实施方式中，壳体10内可以设有导风圈100。导风圈100可以设于进风口101和风机70之间。通过导风圈100可以对从进风口101进入的空气进行导流，以降低噪声，提高运行效率。这样使气流流通阻力小、流入均匀、气流实效流量大，同时，也使气流相对均匀平缓、流入至风机70的气流不易发生紊乱。
图8为图1中A处放大图。结合图8，在一些实施方式中，接水盘40可以设有供换热器30的下端容置的第二凹槽401。第二凹槽401的槽底面向下凹陷形成有排水槽402。排水槽402的槽底设可以有支撑凸筋403。换热器30与支撑凸筋403的顶端面相抵接，以通过凸筋支撑换热器，从而有效防止换热器与排水槽的槽底贴合，使得接水盘上排水顺畅而不易结冰堵塞。
图9为图1中天花机的接水盘的结构示意图。结合图1、图8和图9，在一些实施方式中，排水槽402位于第二凹槽401的外侧，以便于将冷凝水排出接水盘40。当然，在其它实施方式中，排水槽402也可设置在第二凹槽401的内侧，或者设置在第二凹槽401的中部。图11为图9中接水盘中支撑凸筋与换热器翅片的配合示意图。结合图11，需要说明的是，换热器30包括内排换热器30和外排换热器30。虽然第二凹槽401上由于设置了排水槽402而形成台阶面，但由于受到换热器30自身的重力作用，外排换热器30的翅片302非常容易与排水槽402的槽底接触而造成冷凝水流动不顺畅的情况。在一些实施方式中，技术方案通过在排水槽402槽底设置支撑凸筋403，使得支撑凸筋403与翅片302相互垂直，以有效支撑换热器30，并防止换热器30下坠而与接水槽槽底接触。
在一些实施方式中，支撑凸筋403整体为长条形，并沿接水槽的延伸方向延伸。另外，支撑凸筋403的横截面为梯形，以提升支撑凸筋403支撑的稳定性。当然，在其它实施方式中，支撑凸筋403整体还可以为弯折形、波浪形、网格形等其它形状。支撑凸筋403的横截 面也可以为正方形、长方形、三角形等其它形状。本公开不对支撑凸筋403的具体形状进行限制，只要支撑凸筋403相对排水槽402的槽底向上突起而起到支撑换热器30的作用即可。
结合图9，在一些实施方式中，排水槽402可以呈环形设置。排水槽402可以沿接水盘40的周向方向延伸。在一些实施方式中，第二凹槽401可以呈环形设置，以便于容置换热器30的环形下端。而排水槽402也可以同样呈环形设置。具体的，排水槽402相当于包括四个流水槽，四个流水槽分别沿接水盘40的四个侧边延伸，四个流水槽之间可以相互断开或相互连通。在一些实施方式中，四个流水槽基本首尾相互连通形成环形排水槽402，但其中两个相邻的流水槽在接水盘40的角部处断开。可以理解，在一些实施方式中，在排水槽402呈环形设置的情况下，当环形换热器30上的冷凝水向四周流动时，都能够流入排水槽402中，即环形排水槽402能够提升对冷凝水的承接率。
在一些实施方式中，排水槽402内设有多个支撑凸筋403，多个支撑凸筋403沿接水盘40的周向间隔排布。当然，在其它实施方式中，接水槽中可以仅设一整条支撑凸筋403，并沿环形接水槽的延伸方向延伸。但相较而言，本公开的一些实施方式中的技术方案能够有效节省支撑凸筋403的用料，以及减少支撑凸筋403对排水槽402中水流的阻碍。
图10为图9中B处放大图。结合图9和图10，在一些实施方式中，第二凹槽401的槽底面还可以向下凹陷形成有多个排水支槽404。多个排水支槽404可以均位于所述排水槽402的内环侧，且可以均与所述排水槽402连通。可以理解，当有冷凝水从换热器30的内侧流下时，冷凝水可以先流入排水支槽404内，然后排水支槽404的水再流入排水槽402内。而当有冷凝水则从换热器30的外侧流下时，冷凝水会直接流到排水槽402内。一些实施方式中的技术方案能够有效防止蒸发器内侧积水，换热器30上的冷凝水都可以汇入排水槽402内，再集中排出接水盘40之外。
结合图10，在一些实施方式中，排水支槽404可以具有相对的第一槽侧壁和第二槽侧壁。第一槽侧壁可以设有至少一个第一挡水筋405，第二槽侧壁可以设有至少两个第二挡水筋406，第一挡水筋405与第二挡水筋406交错排布。可以理解，当风机70驱动空气向四周吹出时，会有气流吹向排水支槽404内，当排水支槽404内有水时，通过在排水支槽404内设置挡水筋，能够避免排水支槽404内的水飞溅起来，可以防止水落在天花机内的其他零部件上。第一挡水筋405与第二挡水筋406交错排布，能够尽可能地减少挡水筋对水流的阻碍，有利于排水支槽404的水能够顺畅流入排水槽402内。
结合图8，在一些实施方式中，支撑凸筋403的顶端面可以高于第二凹槽401的槽底面。在其它实施方式中，支撑凸筋403的顶端面可以与第二凹槽401的槽底面齐平，或者支撑凸筋403的顶端面低于第二凹槽401的槽底面，只要支撑凸筋403能够支撑起换热器30，避免换热器30与排水槽402的槽底面接触即可。一些实施方式中的技术方案，通过将支撑凸筋403高于第二凹槽401的槽底面设置，能够尽量减少换热器30与接水盘40盘面的接触，进一步提升冷凝水流动的顺畅性。
结合图1和图8，在一些实施方式中，换热器30与第二凹槽401的槽底面之间设有密封件407。由于换热器30与第二凹槽401的槽底面之间存在间隙，当风机70驱动空气向四周吹出时，容易将第二凹槽401上的冷凝水通过间隙吹出，引起吹水现象。一些实施方式中的技术方案通过密封件407的遮挡作用，能够有效避免发生吹水现象。在一些实施方式中，密封件407可以设置为海绵件。海绵件的吸水性能好，有利于提升密封件407的吸水性能。同时，海绵件上的水还可以方便流入排水支槽404和排水槽402内。
在一些实施方式中，排水槽402的槽底与换热器30可以相距3～5mm，即支撑凸筋403相对于排水槽402的槽底向上突起的高度范围可以为3～5mm。可以理解，排水槽402的槽底与换热器30相距不宜过大也不宜过小。排水槽402的槽底与换热器30之间如果相距过大，换热器30与第二凹槽401的槽底之间的间隙也较大，更容易引发吹水现象，因此需要提升密封件407的厚度。如果排水槽402的槽底与换热器30之间相距过小，支撑凸筋403不能很好地将换热器30支撑起来，使得换热器30出现局部与排水槽402槽底接触的情况，则会不利 于排水槽402上冷凝水流动的顺畅性。
结合图9，在一些实施方式中，排水盘还可以设有水泵抽水槽408。排水槽402与水泵抽水槽408连通，且排水槽402的槽底朝向水泵抽水槽408向下倾斜。可以理解，冷凝水汇入排水槽402后，排水槽402内的冷凝水再流入水泵抽水槽408内，最后通过水泵将冷凝水抽出接水盘40之外。在一些实施方式中，排水槽402的槽底末段朝向水泵抽水槽408向下倾斜的倾斜度为0.5～2°。如此，有利于排水槽402内的冷凝水朝向水泵抽水槽408流动，保证水流通畅。水泵502的进水口与水泵抽水槽408连通。
本公开由于壳体开设有进风口和出风口，支架固定于壳体内，换热器设于壳体内，并固定于支架上，换热器设于进风口和出风口之间。换热器通过支架支撑，空气由进风口进入壳体内，与换热器热交换后，从出风口排出。由于接水盘设于壳体内，并位于换热器下方。所以，当换热器热交换后产生的冷凝水，可以落入接水盘内，避免冷凝水流出，提高用户体验。此外，由于水泵组件设于壳体内，并固定于支架上，水泵组件的进水口与接水盘连通。所以，可以直接将水泵组件安装在支架上，即可完成水泵组件的装配，便于装配，提高装配效率。也就是说，支架不仅支撑换热器，还支撑水泵组件，可以减少零部件，降低成本。当接水盘上有冷凝水时，通过水泵组件将接水盘上的冷凝水排出，避免接水盘上冷凝水溢出，提高用户体验。

尽管已描述了本公开的优选实施方式，但本领域内的普通技术人员一旦得知了基本创造性概念，则可对这些实施方式作出另外的变更和修改。所以，所附权利要求意欲解释为包括优选实施方式以及落入本公开范围的所有变更和修改。
显然，本领域的技术人员可以对本公开进行各种改动和变型而不脱离本公开的精神和范围。这样，倘若本公开的这些修改和变型属于本公开权利要求及其等同技术的范围之内，则本公开也意图包含这些改动和变型在内。
