目前，在真空镀膜设备的使用过程中，真空镀膜设备的蒸发机构、蒸发电极、挡板和真空腔上会沉积膜层，这些沉积的膜层需要及时清除。
发明人研究发现，现有的刀具无法清除真空镀膜设备各个部位的膜层，刀具的功能单一，使用不便，清洁效率低，造成真空镀膜设备的维护较不方便。
为了解决刀具功能单一、使用不便、清洁效率低的问题，发明人经过深入研究，设计了一种清洁刀具。
该清洁刀具可用于清洁真空镀膜设备，例如清洁用于制造动力电池的真空镀膜设备，可以理解，清洁刀具还可用于清洁其他各种杂质或污垢的制造设备，或用于清洁其他各种装置，以及墙壁、地面等待清洁的表面。
本申请第一方面的实施例提出一种清洁刀具。请参照图1至图3，清洁刀具100包括刀片10，刀片10包括第一刀刃11和第二刀刃12，第一刀刃11与第二刀刃12分别设于刀片10的不同侧，第一刀刃11具有尖角111，第二刀刃12为斜面刀刃，第二刀刃12设于刀片10的前端；清洁刀具100还包括设于刀片10背离第一刀刃11一侧的第三刀刃13。
刀片10采用硬质材料制作而成，例如钨钢、合金等等。如此，刀片10具有较高的强度，清洁效率高，且使用寿命较长。
刀片10可呈长条形，但不限于此，例如，刀片10也可呈梯形、三角形、圆柱形或其他形状。其中，梯形、三角形是指刀片10的侧视结构，圆柱形是指刀片10的三维空间结构。
第一刀刃11和第二刀刃12分别设于刀片10的不同侧，例如，第一刀刃11和第二刀刃12设于刀片10的相对两侧，或者，第一刀刃11和第二刀刃12设于刀片10的相邻两侧，如此，第一刀刃11和第二刀刃12可分别使用，彼此不受影响。
尖角111可设于第一刀刃11的末端，末端是指第一刀刃11远离刀片10的本体的末端，第一刀刃11的末端为尖角111，即第一刀刃11的末端所形成的端角为锐角。如此，第一刀刃11可通过尖角111伸入缝隙等狭小空间内，从而清除缝隙等狭小空间内的膜层、残渣或其他污垢。
第二刀刃12为斜面刀刃，即第二刀刃12为通过斜面形成的刀刃。斜面刀刃的刃口可为两个斜面的相交边，此时斜面刀刃为双面刀刃；斜面刀刃的刃口也可为一个斜面与一个平面的相交边，此时斜面刀刃为单面刀刃。第二刀刃12可为单面刀刃或双面刀刃。由于第二刀刃12为斜面刀刃，第二刀刃12能够刮除物体表面的膜层或其他污垢，且不易损伤待清洁表面。
在使用清洁刀具100时，可将第一刀刃11的尖角111伸入缝隙等狭小空间内，以清除缝隙等狭小空间内的膜层、残渣或其他污垢，也可利用第一刀刃11的尖角111去除在物件表面粘结较为牢固的污垢；另外，还可利用第二刀刃12刮除物体表面的膜层或其他污垢，例如，第二刀刃12刮除真空腔的腔体表面附着的膜层。上述清洁刀具100可用于清洁真空镀膜设备，包括真空镀膜设备的蒸发机构、蒸发电极、挡板、辊类机构和真空腔，便于维护和清洁真空镀膜设备，结构简单，功能实用。
本申请实施例提供的清洁刀具100包括刀片10，刀片10包括第一刀刃11和第二刀刃12，第一刀刃11具有尖角111，能够清洁缝隙等狭小空间；第二刀刃12为斜面刀刃，能够清洁各种物件的表面；第一刀刃11与第二刀刃12分别设于刀片10的不同侧，使用功能互不影响。因此，上述清洁刀具100具有多种清洁功能，既能够清洁物件的表面，还可以清洁缝隙等狭小空间，具有较高的清洁效率，结构简单，使用方便。上述清洁刀具100能够有效清洁真空镀膜设备，解决了现有技术中刀具功能单一、清洁效率较低的问题。
刀片10包括刀身101和与刀身101的前端一体设置的刀头102，刀身101具有相对设置的第一侧面1011和第二侧面1012，第一刀刃11设于第一侧面1011或刀头102上。
刀头102设于刀身101的前端，本实施例对刀头102的形状不作限制。
刀身101的第一侧面1011和第二侧面1012为刀身101上较窄的侧面，以便于形成刀刃。在本实施例中，第一侧面1011与第二侧面1012相互平行，在其他实施中，第一侧面1011与第二侧面1012也可倾斜设置。
可以理解，刀身101还包括第三侧面1013和第四侧面(图未示)，第三侧面1013和第四侧面可大致呈矩形，第一侧面1011的两侧连接于第三侧面1013和第四侧面的一端，第二侧面1012的两侧连接于第三侧面1013和第四侧面的另一端。第一侧面1011和第二侧面1012较窄，对应刀身101的厚度，第三侧面1013和第四侧面较宽，对应刀身101的宽度，且第一侧面1011、第二侧面1012、第三侧面1013和第四侧面的长度差异较小，该长度对应刀身101的长度。刀身101和刀头102一体设置，也就是第一侧面1011、第二侧面1012、第三侧面1013和第四侧面于长度方向上的相同端形成了刀头102。
第一刀刃11设于第一侧面1011或刀头102上，即第一刀刃11可设于刀身101的一侧面，也可设于刀头102上，无论设于刀片10的哪一侧，均可利用第一刀刃11上的尖角111清洁缝隙。可以理解，由于第二刀刃12与第一刀刃11设于刀片10的不同侧，若第一刀刃11设于第一侧面1011，则第二刀刃12可设于第二侧面1012或设于刀头102上；若第一刀刃11设于刀头102，则第二刀刃12可设于第一侧面1011或第二侧面1012。
通过采用上述技术方案，刀片10的刀身101具有第一侧面1011和第二侧面1012，第一侧面1011、第二侧面1012和刀头102均可用于形成刀刃，本申请实施例提供的清洁刀具100可灵活地设置第一刀刃11与第二刀刃12的位置，以适配不同的使用需求。
在一实施例中，第一刀刃11呈钩状，且第一刀刃11自第一侧面1011延伸至刀头102，第二刀刃12设于刀头102或第二侧面1012。
请参考图3，第一刀刃11自第一侧面1011延伸至刀头102，具体的，第一刀刃11自 第一侧面1011与刀头102的连接处延伸至刀头102；第一刀刃11呈圆弧形钩状，第一刀刃11的尖角111即为圆弧形钩状结构的钩尖。相应的，第二刀刃12设于刀头102。在另一种实施例中，第二刀刃12也可设于第二侧面1012。
通过采用上述技术方案，第一刀刃11呈钩状，第一刀刃11具有一定的长度，清洁刀具100不仅能使尖角111插入缝隙内，还可使第一刀刃11钩出缝隙内的膜层、残渣或其他污垢，方便快捷的清除干净真空腔的缝隙或凹槽内的杂质，操作省时省力。
可选的，第一刀刃11的厚度自第一侧面1011朝向尖角111逐渐减小，使得第一刀刃11较薄，方便伸入缝隙内。
如图3所示，在一实施例中，沿刀身101的宽度方向，刀头102相对于第一侧面1011凸出，尖角111设于刀头102凸出于刀身101的端部。
刀身101沿第一方向X延伸，第一方向X是刀身101的长度方向，沿垂直于第一方向X的第二方向Y，刀头102相对于第一侧面1011凸出且尖角111设于刀头102上。第二方向Y是刀身101的宽度方向。
沿第二方向Y，刀头102相对于第一侧面1011凸出，第一刀刃11可自第一侧面1011圆滑过度至刀头102凸出于第一侧面1011的端面，以形成钩状的第一刀刃11。
请参照图4，在另一实施例中，沿刀身101的长度方向(第一方向X)，第一侧面1011相对于刀头102凸出且尖角111设于第一侧面1011凸出于刀头102的端部。
沿第一方向，第一侧面1011相对于刀头102凸出，则第一刀刃11可自刀头102圆滑过渡至第一侧面1011凸出于刀头102的端部，以形成钩状的第一刀刃11。
通过采用上述技术方案，第一刀刃11可设于第一侧面1011背离第二侧面1012的一侧，或者设于第一侧面1011朝向第二侧面1012的一侧，第一刀刃11的设置方式灵活；由于第一刀刃11的两端分别延伸至第一侧面1011和刀头102，第一刀刃11的强度较高、不易断裂，使用寿命较长；并且，第一刀刃11的制作方式简单方便。
第一刀刃11的形状不限于圆弧形钩状，只要能在末端形成尖角111即可。请参照图5， 第一刀刃11与第一侧面1011之间呈钝角；请参照图6，第一刀刃11与第一侧面1011之间呈直角。
如图5所示，第一刀刃11的两端分别延伸至刀头102和第一侧面1011，第一刀刃11的刃边为与第一侧面1011倾斜的斜边，同样可以在第一刀刃11的末端形成尖角111，以利用尖角111清洁缝隙；第二刀刃12可设于刀头102或第二侧面1012。
如图6所示，第一刀刃11的刃边自刀头102延伸至第一侧面1011，第一刀刃11与第一侧面1011相垂直，第一刀刃11的刃边为与第一侧面1011垂直的直边；第二刀刃12可设于刀头102或第二侧面1012。
通过采用上述技术方案，第一刀刃11与第一侧面1011之间呈钝角或直角，即第一刀刃11的刃边为直边，第一刀刃11为钝角钩状或直角钩状，同样可实现对缝隙等狭小空间的清洁，清洁刀具100的结构简单，制作和使用均比较方便。
请再次参照图1至3，在一些实施例中，第二刀刃12设于刀片10的前端，清洁刀具100还包括设于刀片10背离第一刀刃11一侧的第三刀刃13，即第三刀刃13设于第二侧面1012。
第二刀刃12设于刀片10的前端，即第二刀刃12设于刀头102上且位于刀头102背离刀身101的一侧，同时，第一刀刃11自第一侧面1011延伸至刀头102，因此，第一刀刃11可与第二刀刃12相连，第一刀刃11与第二刀刃12之间没有间隙，方便使用。第三刀刃13的结构可与第一刀刃11或第二刀刃12相同，也可与第一刀刃11、第二刀刃12均不同，以进一步丰富清洁刀具100的功能。相似的，请参照图5至图7，清洁刀具100也包括第一刀刃11、第二刀刃12和第三刀刃13。在其他实施例中，例如图4所示的实施例，清洁刀具100也可仅包括第一刀刃11和第二刀刃12。
由于第一刀刃11设于第一侧面1011，第二刀刃12设于刀头102上，第三刀刃13设于第二侧面1012，如此，刀片10的三侧分别设有刀刃，提升了清洁的刀具的使用功能和清洁效率。
请参照图1至图3、图5至图6，第三刀刃13为斜面刀刃。
第三刀刃13与第二刀刃12均为斜面刀刃，均可用于铲除或刮除物件表面的膜层或其他杂质。由于第二刀刃12设于刀头102且第三刀刃13设于第二侧面1012，第二刀刃12与第三刀刃13可相连接，即第二刀刃12与第三刀刃13之间没有间隙，第二刀刃12与第三刀刃13的连接点形成一个尖端，可以用于清除难以清理的污垢。可以理解，第二刀刃12与第三刀刃13也可不连接。
在使用时，可使用清洁刀具100的第一刀刃11清洁缝隙内的杂质，使用第二刀刃12或第三刀刃13清洁物件表面，第二刀刃12与第三刀刃13的方向不同，可适用于不同的握持方式和行进方向，以适配不同清洁面的需求，或适配不同的使用习惯。另外，由于第二刀刃12和第三刀刃13均可用于清洁物件表面，无需频繁清洁刀刃上的污垢，降低了对清洁刀具100的清洗频率，提升了清洁效率。
可选的，第三刀刃13的刃口长度大于第二刀刃12的刃口长度。
具体的，在一实施例中，第二刀刃12、第三刀刃13均为斜面刀刃，第二刀刃12的刃口沿着第二方向Y延伸，第三刀刃13的刃口沿着第一方向X延伸，因此，第三刀刃13的刃口长度即第三刀刃13沿第一方向X延伸的长度，第二刀刃12的刃口长度即为第二刀刃12沿着第二方向Y延伸的长度。
由于第三刀刃13的刃口长度大于第二刀刃12的刃口长度，在使用时，可推动刀片10沿第一方向X移动并通过第二刀刃12铲除平面上的污垢和膜层，清洁时的阻力较小；然后，利用第三刀刃13将清洁后的污垢和膜层打扫出来。当然，也可利用刃口长度不同的第二刀刃12和第三刀刃13分别清洁宽度不同的表面。
通过采用上述技术方案，可分别利用第二刀刃和第三刀刃清洁宽度不同的表面；另外，清洁刀具100可利用第三刀刃13打扫和归集铲掉的污垢和膜层，进一步提升了刀具使用的便利性，以及提升了清洁效率。
可以理解，在其他实施例中，第三刀刃的长度也可等于或小于第二刀刃12的刃口长 度，另外，第二刀刃、第三刀刃的延伸方向也可相对于第一方向X倾斜设置。
在一些实施例中，第二刀刃12和第三刀刃13中的至少一者为单面刀刃。
可选的，第二刀刃12和第三刀刃13均为单面刀刃，第二刀刃12的刃口为一个斜面与第四侧面的相交边，第三刀刃13的刃口为另一个斜面与第四侧面的相交边，第四侧面可为平面。
可选的，第二刀刃12和第三刀刃13中的一者为单面刀刃，另一者为双面刀刃。
通过采用上述技术方案，单面刀刃能够更好地贴合于光滑的表面，例如真空腔的内壁面，清洁刀具100可使用第二刀刃12或第三刀刃13方便地清除表面光滑物件的膜层，避免膜层铲除不净的问题。
在一些实施例中，第二刀刃12的刃口斜度为60度至85度。
在一些实施例中，第三刀刃13的刃口斜度为60度至85度。
在一些实施例中，第二刀刃12和第三刀刃13的刃口斜度均为60度至85度。
其中，刃口斜度即形成刃口的两个表面之间的夹角，当刀刃为单面刀刃时，刃口斜度为形成刃口的斜面与第四侧面之间的夹角。
刃口斜度为60度至85度，可使刃口较为锋利，便于清除物件表面的膜层或其他污垢。
在一实施例中，第二刀刃12的刃口斜度为75度；在一些实施例中，第三刀刃13的刃口斜度也为75度。在一些实施例中，第二刀刃12和第三刀刃13的刃口斜度均为75度。
可选的，第二刀刃12和第三刀刃13的刃口斜度均为75度，如此两个刀刃均可有效清洁物件的表面；可以理解，也可将第二刀刃12和第三刀刃13中一者的刃口斜度设置为75度，另一者的刃口斜度可选自60度至85度的范围，使用刃口斜度为75度的刀刃来清洁真空腔的上壁面、侧壁面，使用另一刀刃来清洁真空腔的底面。
通过采用上述技术方案，当刃口斜度为75度时，该刀刃可有效地清洁物件的表面。
第三刀刃13的形状不限于斜面刀刃。请参照图7，在一些实施例中，第三刀刃13为钩状刀刃且第三刀刃13自刀片10背离第一刀刃11的一侧延伸至刀片10的前端，刀片10 的前端为刀头102，即第三刀刃13自第二侧面1012延伸至刀头102。
具体的，清洁刀具100包括第一刀刃11、第二刀刃12和第三刀刃13，第一刀刃11为圆弧形钩状且自第一侧面1011延伸至刀头102，第二刀刃12设于刀头102背离刀身101的一侧，第三刀刃13为圆弧形钩状。
可选的，第二刀刃12的两端分别凸出于刀身101，第二刀刃12大致呈燕尾型。
通过采用上述技术方案，清洁刀具100可利用第一刀刃11或第三刀刃13来清洁缝隙内的膜层或其他杂质，即使第一刀刃11和第三刀刃13中的一者断裂也不影响清洁刀具100的使用功能，提升了清洁刀具100的使用寿命。
在一实施例中，第二刀刃12的两端分别连接第一刀刃11与第三刀刃13。
第二刀刃12的一端与第一刀刃11连接，二者之间没有间隙；第二刀刃12的另一端与第三刀刃13连接，二者之间没有间隙。
如此，清洁刀具100的每个刀刃均可具有较高的强度，使用过程中不易发生断裂，且可避免污垢藏于相邻的刀刃之间。
请再次参照图1至图3，清洁刀具100还包括刀柄20，刀柄20可拆卸地连接于刀片10的一端。刀柄20包括两个固定部21，刀片10夹持于两个固定部21之间。
刀柄20便于使用者握持清洁刀具100，刀柄20的材质可为不锈钢等硬质材料，也可为木制、塑料等。
在其他实施例中，刀柄20也可以省略。
通过采用上述技术方案，刀柄20可拆卸地连接于刀片10的一端，清洁刀具100的制作方式简单，且刀柄20的设置便于使用者握持清洁刀具100，提升了操作的便利性。
在一实施例中，每个固定部21上设有连接孔211，刀片10上设有与连接孔211对应的通孔1014，刀柄20与刀片10通过穿设于通孔1014和连接孔211中的紧固件30固定连接。
固定部21可沿着刀身101的延伸方向延伸且具有一定的长度，以方便握持；两个固 定部21可为分体结构，也可为一体结构。刀片10上的连接孔211设于刀身101背离刀头102的一端，连接孔211的数量可为一个或多个；紧固件30可为铆柱、螺钉等连接紧固件30。
在组装时，将两个固定部21分别置于刀片10的两侧，然后将紧固件30固定穿设于两个固定部21的连接孔211和刀片10的通孔1014内即可。
通过采用上述技术方案，清洁刀具100的结构简单，组装方便，刀柄20的实用性较强。
如图1至图3所示，在一实施例中，清洁刀具100包括刀片10和可拆卸地连接于刀片10的刀柄20，刀柄20用于握持以操控刀片10。刀片10包括刀身101和与刀身101的前端一体设置的刀头102，刀身101具有相对设置的第一侧面1011和第二侧面1012，刀片10上设有第一刀刃11、第二刀刃12和第三刀刃13，其中，第一刀刃11呈圆弧形钩状，且第一刀刃11自第一侧面1011延伸至刀头102；第二刀刃12和第三刀刃13均为单面刀刃，第二刀刃12设于刀头102且第三刀刃13设于第二侧面1012。
以用于清洁真空镀膜设备为例，第一刀刃11用于清除真空腔或真空镀膜设备的其他结构件的缝隙内的膜层、残渣或其他污垢，第二刀刃12和第三刀刃13均可用于刮除蒸发机构、蒸发电极、挡板和真空腔的腔壁上的膜层或其他污垢，且第三刀刃13还可清扫刮掉的污垢。
因此，上述实施例的清洁刀具100能够有效清洁和维护真空镀膜设备或其他设备，具有多种清洁方式和清洁功能，结构简单，使用方便，提升了清洁效率。
