参照图1，本发明的一个实施例中的蒸发器喷涂防护装置，用于夹持在空调蒸发器的端部，在对蒸发器端部的外露管路和管板进行喷涂处理时，遮挡住内侧的蒸发器翅片，防止喷漆喷到蒸发器翅片上。其中，本实施例中的蒸发器10为三段式蒸发器(参见附图5所示)。在本实施例中蒸发器的内侧面是指向内弯折的一侧面，安装时位于空调器的内侧，安装时朝向空调器外侧的为蒸发器的外侧面。
如图1所示，蒸发器喷涂防护装置包括框架100和多个遮挡组件。框架100由边板围绕形成，框架100内部用于容置蒸发器的端部。边板包括相铰接的第一边板110和第二边板120。第一边板110和第二边板120分别具有三条折边，围成的框架100为六边形。具体地，第一边板110的一端与第二边板120的一端通过螺栓或转轴铰接，第一边板110的另一端和第二边板120的另一端通过连接结构可拆卸地连接。使用时，如图2所示,可以通过连接结构将第一边板110和第二边板120打开，方便对蒸发器进行夹持操作。
连接结构可以为卡接结构400，具体地，卡接结构400包括设置在第二边板120端部的卡槽400b，卡槽与第一边板110相匹配，第一边板110的端 部卡入卡槽固定。卡槽可以由弯折件400a与第二边板120固定后之间形成的缝隙形成。在其他的实施例中，连接结构可以设置为磁吸结构，使第一边板110与第二边板120通过磁铁相互吸附固定。或卡扣、魔术粘等可拆卸结构。
遮挡组件包括挡板和连接板，连接板与边板滑动连接，挡板位于框架100内部且与连接板转动连接。多个挡板能够分别沿垂直于蒸发器端部的平面方向，与蒸发器端部的内外侧面相抵接。也即是，多个挡板能够在蒸发器的呈三折的端部截面所在的平面内转动或移动以与蒸发器端部的内外侧面相抵接。
具体地，多个遮挡组件包括一组内侧面遮挡组件300和三组外侧面遮挡组件200。第一边板110的每条折边上分别连接有一组外侧面遮挡组件200；第二边板120中的一折边上连接有内侧面遮挡组件300。挡板包括直挡板220和扇形挡板320，连接板包括第一连接板210和第二连接板310。

由于蒸发器的内侧面空间较小，不便于设置多组遮挡组件进行遮挡，因此，如图4所示，内侧面遮挡组件300包括扇形挡板320和第二连接板310，扇形挡板320的两条直边能够与蒸发器的内侧面相抵接，扇形挡板320能够 沿第二连接板310转动。根据蒸发器内侧面形状，通过调节第二连接板310和扇形挡板320的位置，可以方便实现贴合遮挡。具体地，扇形挡板320包括第一扇形挡板321和第二扇形挡板322，第一扇形挡板321与第二扇形挡板322相叠合并能沿圆心相互转动。也即是，第一扇形挡板321的扇形圆心与第二扇形挡板322的扇形圆心相叠合并能沿该圆心相互转动。通过调节第一扇形挡板321和第二扇形挡板322转动角度，可以控制扇形挡板320的大小，可以方便根据蒸发器的不同型号，进行调整，通用性强。
内侧面遮挡组件300设置在第二边板120上。第二连接板310与第二边板120滑动连接，具体地，第二连接板310设置在与第一边板110相铰接的第二边板120折边上，第二连接板310的一侧能够使第二连接板310的一侧边与蒸发器的内侧面相抵接。通过调节第二连接板310的移动距离和扇形挡板320的转动角度，使第二连接板310和扇形挡板320与蒸发器的内侧面紧密抵接贴合。具体地，第二连接板310上开设有第二滑槽311，第二边板120上开设有第三滑槽122，第二滑槽311和第三滑槽122之间通过第二限位件520滑动连接。第二连接板310可以沿第二边板120的第三滑槽122移动，可以同时通过自身的第二滑槽311移动。
第一扇形挡板321与第二连接板310的连接结构具体为，第一扇形挡板321上开设有第四滑槽3211，第二连接板310固定设置有与第四滑槽3211相配合的第三限位件530，第三限位件530设置在第四滑槽3211内，第一扇形挡板321通过第四滑槽3211沿第三限位件530转动和滑动。
为了对第一扇形挡板321和第二扇形挡板322之间展开角度进行限位，防止第二扇形挡板322与第一扇形挡板321之间转动了较大角度出现空隙，第二扇形挡板322开设有弧形滑槽3221，第一扇形挡板321上开设有与弧形滑槽3221性配合的第四限位件540，第四限位件540设置在弧形滑槽3221内，第二扇形挡板322通过弧形滑槽3221沿第四限位件540滑动。
在其他的实施例中，框架100可以为其他形状如圆形或多边形。
蒸发器如为平板型或L型结构时，根据上述实施例中的结构原理，相应设置合理数量的遮挡组件。蒸发器为平板型时，此时内侧面的遮挡组件可以采用直挡板220。
上述的第一限位件510、第二限位件520、第三限位件530、第四限位件540优选使用一种固定件，如同一种固定螺栓。
本实用新型蒸发器喷涂防护装置，利用多个遮挡组件，可以根据蒸发器的形状进行调节，与蒸发器的内外侧面贴合紧密，有效防护，保证喷涂过程中无喷漆盼到蒸发器翅片上；结构简单，滑动或转动遮挡组件即可调节，操作简便；喷涂防护装置可以重复使用，环保节约，降低了成本。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
