图1为本发明实施例提供的一种蔬菜保鲜种植箱的结构示意图。图2为本发明蔬菜保鲜种植箱中的电控组件与控制组件的连接示意图。如图1和图2所示，该蔬菜保鲜种植箱包括：
保温箱体10、用于对保温箱体10进行电控的电控组件、用于调节保温箱体10内温度、湿度和/或光照的控制组件、以及用于向保温箱体10内循环供给营养液体的管路组件。
至少一个蔬菜承载件11被设置在保温箱体10中，该蔬菜承载件11用于种植或保鲜蔬菜。通过在保温箱体10中设置蔬菜承载件11，并通过管路组件使得营养液在箱体内循环，并且通过将保温箱体10内温度、湿度和/或光照调节到蔬菜生菜生长所需的范围内，使得蔬菜承载件11上的蔬菜能够在其所需的生长环境中营养，即使蔬菜被采摘之后，也能够处于停滞生长或缓慢生长的状态，长时间得到保鲜。
该电控组件和管路组件具体可设置在保温箱体10的壳体上。该蔬菜承载件11可与管路组件水路连通。
可选地，控制组件包括设于保温箱体10中、用于自上而下向各蔬菜承载件11提供光照的光照组件22，该电控组件用于控制光照组件22的状态。例如，可在每个蔬菜承载件11的上方设置与电控组件电连接的导光板，通过电控组件可将导光板的光强控制在适宜蔬菜承载件11上的蔬菜生长的光强范围内。
通过光照组件自上而下向蔬菜承载件11提供光照，并通过电控组件对其状态进行控制，不仅能够保证光照的均匀度，并且能够根据实际需要进行调节，可为蔬菜承载件11上的蔬菜提供所需的光照环境，有利于蔬菜生长或保鲜。
具体地，本发明的蔬菜保鲜种植箱的保温箱体10可设置有多个蔬菜承载件11，且该多个蔬菜承载件11自上而下平行间隔设置。通过这种方式，可使不同种类的蔬菜放置于不同的蔬菜承载件11上，便于用户取放，并且可实现不同的区域具有不同的环境，有利于对不同种类的蔬菜进行生长或保鲜控制。
进一步，位于上方的蔬菜承载件11的底部设有用于为其下方的蔬菜承载件11提供光照的该光照组件22，即，设于任一蔬菜承载件11底部的光照组件22可用于为其下方的蔬菜承载件11提供光照，实现了自上而下向蔬菜承载件11提供光照。通过这种方式，可节省空间，并且结构简洁，布线方便。
进一步，用于为最上层的蔬菜承载件11提供光照的光照组件可设置在保温箱体10内部空间的顶部。
可选地，每个蔬菜承载件11可插拔地设置在保温箱体10中，并与电控组件可插拔地电连接，当某一蔬菜承载件11从保温箱体中拔出并与电控组件断开电路连接时，该电控组件可联动地控制该蔬菜承载件11与管路组件断开水路连接。
通过上述方式，使得蔬菜承载件11可方便地从保温箱体10中抽出，方便蔬菜的取放并且方便维修。另外，使得每个蔬菜承载件11可单独工作，在从保温箱体10中取出后，不影响其它蔬菜承载件11的正常工作，并且，通过电路连接和水路连接联动，避免了蔬菜承载件11被取出时出现漏水。
作为一种具体的实施方式，可在管路组件上与每个蔬菜承载件11的水路连接处设置可插拔的接头，并在该接头处设置阀门，当电控组件与某一个蔬菜承载件11断开电路连接后，电控组件立即控制对应的阀门关闭，以阻断管路组件中的营养液向该蔬菜承载件11的通路。
可选地，每个蔬菜承载件11上设有用于雾化营养液的雾化器24，电控组件还用于控制该雾化器24的状态。
通过雾化营养液，有助于蔬菜吸收营养，更有效地得到保鲜。并且通过电控组件控制雾化器24的状态，可以控制保温箱体10中的湿度，还可控制蔬菜吸收营养的程度，使得蔬菜生长处于可控的状态。
雾化器24具体可设置在蔬菜承载件11底部的中心处，有助于蔬菜从根部、均匀地吸收营养。
具体地，每个蔬菜承载件11包括溶液承载盒和位于溶液承载盒上方的蔬菜隔板，该雾化器24可设置在溶液承载盒中。蔬菜隔板上可设置多个连通至该溶液承载盒的通孔，用于使蔬菜的根部插入其中。
进一步，溶液承载盒内由突起的导流隔断形成曲折的液流通道，且蔬菜隔板相对该液流通道的顶部架空。通过设置导流隔断，可避免溶液承载盒内形成滞留营养液的死角，有利于营养液流畅地循环。并且，使得蔬菜隔板相对于液流通道的顶部架空，可避免蔬菜根部浸在液体中而变地腐烂，保持营养液的清洁，通过雾化气体溶度可以调节为蔬菜提供的养分，从而实现生长状态可控。
图3为本发明蔬菜保鲜种植箱的管路组件的结构示意图，参考图3，上述管路组件包括上容器32、下容器34和连通上容器32、下容器34的液体循环管路36，液体循环管路36自上而下至少间隔开设有两个通孔362，并经上述通孔362与对应的至少两个蔬菜承载件11连通。上容器32可设置在保温箱体10的顶部，下容器34可设置在保温箱体10的底部。
因此，营养液可依次在上容器32、液体循环管路36、每个蔬菜承载件11和下容器34之间循环形成单独的循环通路。通过这种方式，可使得每个蔬菜承载件11可以单独工作，并在断开与液体循环管路36的水路连接时不影响其它蔬菜承载件11的正常工作。另外，通过这种方式，营养液可在从下容器34流向上容器32之后分流至向各蔬菜承载件11，避免了由于蔬菜承载件11的高度不均造成的液压不同、进而营养液供应不均的问题。
进一步，每个蔬菜承载件11包括高位进液口和低位出液口，该高位进液口和上容器32连通，低位出液口和下容器34连通，上容器32中的营养液基于重力作用经每个蔬菜承载件11回流至下容器34。营养液基于重力作用流经蔬菜承载件11，使营养液以较慢的速度进行循环，可在不增加成本的基础上，避免循环速度过快造成的蔬菜生长环境不适的问题。由以上描述可知，高位进液口和低位进液口具体可设置在溶液承载盒上。
可选地，液体循环管路36上可设置有用于控制各通孔362的水流通断的阀门，电控组件还用于控制各阀门的状态。通过控制对应各通孔362的阀门的通断，可控制液体循环管路36和各蔬菜承载件11之间的水路连通或断开，进而，在实现电路控制的同时，可联动地控制蔬菜承载件11和管路组件之间的水路连接。例如，当电控组件与其中一个蔬菜承载件11的电路接口断开连接后，通过关闭对应的阀门，可控制连接至该蔬菜承载件11的水路（为该蔬菜承载件11供应营养液的液体通道，即与该蔬菜承载件11连通的通孔362）也断开；当蔬菜承载件11重新进入保温箱体10时，其电路接口与电路组件重新连接，通过开启该阀门可重新导通该通孔与蔬菜承载件11。
具体地，液体循环管路36可通过可插拔接头与各蔬菜承载件11连通，通过可插拔接头连接蔬菜承载件11和液体循环管路36，便于维修，并且容易操作，容易通过微调改正较小的插接错位。例如，各可插拔接头可设置在液体循环管路36的通孔362和蔬菜承载件11的高位进液口的连接处，或者，可设置在液体循环管路36的通孔362和蔬菜承载件11的低位出液口的连接处，其具体可包括钢芯接头和包覆在钢芯接头外围的柔性材料层。当蔬菜承载件11从保温箱体10取出时，各接头也随之分别从上述液体循环管路36中拔出，在重新将蔬菜承载件11插入保温箱体10中时，通过钢芯接头外围的柔性材料，在插接过程中有较小错位的情况下，对插接位置进行微调，可方便地与管路组件上的接头匹配，使蔬菜承载件11更容易插接至保温箱体10，并实现蔬菜承载件11与液体循环管路36的水路连通。
该可插拔接头的周围可设有连通下容器34的导流槽，这样，当蔬菜承载件11与液体循环管路36之间断开水路连接时，可通过该导流槽将可插拔接头中残余的液体导流至下容器34中，进一步避免漏水引起的安全问题。
上述阀门具体可对应设置在可插拔接头上。并且，可插拔接头的外围还可设置突出部，在液体循环管路36上方发生漏水的情况下，漏出的水可沿着该突出部滴向下容器34，避免接触到接头上的电器部件，例如用于控制水路通断的阀门。
可选地，上述控制组件还包括热泵系统，上述电控组件还用于控制热泵系统的状态。本领域技术人员应该理解，在一种实施方式中，该热泵系统可包括互相连通的压缩机、冷凝器和蒸发器，电控组件具体可与压缩机连接以控制其状态，进而控制保温箱体10的温度，使之维持在适宜蔬菜缓慢生长的范围内。
可选地，保温箱体10中还设有用于向电控组件发送温度感应信号的温度传感器和/或用于向电控组件发送湿度感应信号的湿度传感器和/或用于向电控组件发送浓度感应信号的浓度传感器。该电控组件具体可根据该温度感应信号控制热泵系统的状态，或者根据该湿度感应信号控制保温箱体10内的加湿器（例如各雾化器24）的状态，通过设置温度和湿度传感器，可使温度和湿度的控制更精确，并且能够及时发现异常。该浓度传感器具体可设置在上容器32中，避免针对每个蔬菜承载件11设置浓度传感器。通过浓度感应信号，还可以判断营养液是否充足。
可选地，保温箱体10的外壳上设有与电控组件连接的控制面板。该控制面板具体可用于显示例如温度、湿度、光照强度等控制参数，还可用于接收用户的控制指令，进而通过电控组件进行各种控制操作。
参见图4所示，为本发明的蔬菜生态保鲜方法的一种实施方式的流程图。
在本实施方式中，蔬菜生态保鲜方法包括：
S10：为保温箱体内的蔬菜循环供给营养液。
保温箱体例如可以是冰箱，酒柜以及类似具有密闭空间的箱体。
向植物输送养分，可以使得植物更好的保留其自身的养分，并持续处于新鲜状态。
以及，
S20：调节保温箱体内的温度、湿度和/或光照，以使保温箱体内的蔬菜处于停滞或缓慢生长的状态。
作为一种优选方式，可以采用闭环控制的方法来调整保温箱体内的温度和/或湿度。即，通过温度和/或湿度传感器采集保温箱体内的温度和/或湿度信号并反馈至温度和/或湿度控制器。温度和/或湿度控制器根据当前保温箱体内的温度和或/湿度，以及目标温度和/或湿度之间的差值，来调节箱体内的温度和/或湿度达到目标温度和/或湿度。
通过对保温箱体内的蔬菜循环供给营养液，并调节其温度、湿度和/或光照，可以使得箱体内的蔬菜处于缓慢生长或者生长停滞状态，从而最大程度的保证蔬菜的新鲜程度，延长保鲜时间。
参见图5所示，为用于实现本发明的一种实施方式的蔬菜生态保鲜方法的保温箱体结构。
可以在保温箱体10内上下平行间隔设置至少二个（例如，三个）蔬菜承载件11用于保鲜蔬菜，并将蔬菜承载件11与用于为保温箱体10内的蔬菜循环供给营养液的营养液循环管路12（营养液循环管路12即为管路组件）连通，从而实现蔬菜生态保鲜。
在一种实时方式中，营养液循环管路12中的营养液可以按照图5中箭头所示的方向进行循环流动，从而为各蔬菜承载件11中放置的蔬菜进行营养液供给。
参见图6，为用于实现本发明的一种实施方式的蔬菜生态保鲜方法的保温箱体10中的蔬菜承载件11的一种实施方式的结构图。
如图6所示，可以在蔬菜承载件11上开设高位进液口111和低位出液口115来连通营养液循环管路12，使营养液循环管路12上流动的营养液基于重力作用经蔬菜承载件11流回至营养液循环管路。让营养液基于重力作用流动，可以节省能源，从而节省保温箱体的耗电量。高位进液口111和低位出液口115可以设置在蔬菜承载件11的同一个侧壁上。
如图6所示，还可以通过在蔬菜承载件11的位于高位进液口111和低位出液口115之间的区域由凸起的导流隔断113形成的曲折液流通道112，使流入蔬菜承载件11内的营养液通过曲折的液流通道112在蔬菜承载件11内向低位出液口115扩散式流动。通过液流通道112的导流，可以使得营养液更加均匀的流动，从而更好地为蔬菜承载件11中放置的所有蔬菜提供营养。
如图6所示，还可以在蔬菜承载件11内设置雾化器116，从而对流入蔬菜承载件11内的营养液进行雾化处理。向放置在蔬菜承载件11中的蔬菜喷洒经雾化的营养液，可以使得蔬菜更充分地吸收营养液，雾化后喷洒更加均匀，且节省营养液。在一种实施方式中，雾化器11例如可以设置于蔬菜承载件11底部的中心区域。
如图6所示，还可以在蔬菜承载件11上部设置开设有通孔119的蔬菜搁板118，将待保鲜的蔬菜插入通孔119，且通孔119中插入的蔬菜的根系架空于蔬菜承载件11内的营养液液面上方。这样，可以通过雾化器116向蔬菜的根系喷洒经雾化的营养液。
为了调节保温箱体10内的光照，可以通过自上而下的方式调节为所述保温箱体内的蔬菜提供的光照。
例如，可以通过设置在位于上方的蔬菜承载件11的底部的第一光照组件，来调节位于其下方的蔬菜承载件11内承载的蔬菜所提供的光照。不同蔬菜承载件11底部的第一光照组件可分别控制，以满足不同蔬菜保鲜所需的光照。
除此之外，还可以通过调节在保温箱体10顶部内壁上设置的第二光照组件，来调节为第一层的蔬菜承载件11内承载的蔬菜所提供的光照。
作为一种优选方案，蔬菜生态保鲜方法还可以包括：建立保温箱体10和蔬菜承载箱11之间建立可插拔式电连接。
例如，可以检测蔬菜承载件11与保温箱体10是否电连接，如果电连接，则导通营养液自营养液循环管路到相应蔬菜承载件11的流通通路，否则，截止流通通路。这样，可以避免营养液渗漏，保证保温箱体10的清洁。
采用本发明的蔬菜生态保鲜方法，通过为蔬菜循环供给营养液并调节所述保温箱体内的温度、湿度和/或光照，可以控制蔬菜的生长状态，使所述保温箱体内的蔬菜处于停滞或缓慢生长的状态，从而最大程度的保证蔬菜的新鲜程度，延长保鲜时间
