图3为图1中加热套（包括第一加热套、第二加热套以及第三加热套）的结构示意图。
具体实施方式
下面将结合本申请实施例中的附图，对实施例中的技术方案进行清楚、完整地描述，附图中类似的组件标号代表类似的组件。显然，以下将描述的实施例仅仅是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，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，都属于本申请保护的范围。
应当理解，当在本说明书和所附权利要求书中使用时，术语“包括”和 “包含”指示所描述特征、整体、步骤、操作、元素和/或组件的存在，但并不排除一个或多个其它特征、整体、步骤、操作、元素、组件和/或其集合的存在或添加。
还应当理解，在此本申请实施例说明书中所使用的术语仅仅是出于描述特定实施例的目的而并不意在限制本申请实施例。如在本申请实施例说明书和所附权利要求书中所使用的那样，除非上下文清楚地指明其它情况，否则单数形式的“一”、“一个”及“该”意在包括复数形式。
参见图1-2，本申请实施例提供的一种液晶滴下装置，由图可知，所述液晶滴下装置包括加热保温装置，所述加热保温装置包括：加热组件4、检测组件5以及控制单元6，各部件的介绍如下：
加热组件4，用于对液晶滴下装置内的液晶进行加热。检测组件5，用于检测液晶滴下装置内的液晶的温度。控制单元6，分别与加热组件4以及检测组件5连接，用于根据检测组件5获取的温度对加热组件4进行调控，以使液晶滴下装置内的液晶的温度恒定为预设的温度值。其中，预设的温度值可由用户自行设定。
