本实施例的壳体1与盖板3采用相同的材质，因此具有相同的性能，注塑成型工艺中容易实现良好的连接，有效的提高了风道的密封性。
在一些实施例中，参阅图1，壳体1与盖板3的材质不相同。
在一些示例中，参阅图1，壳体1的材质为ABS材料。盖板3为复合结构，包括ABS材料层及玻璃纤维层。
示例的，盖板3的ABS材料层及玻璃纤维层的设置方式包括但不限于层叠设置、往复交叉设置及混合设置。
示例的，盖板3的ABS材料和玻璃纤维的含量比例不同，相差5％～30％。
具体的，盖板3包括ABS材料及玻璃纤维，与ABS材料的壳体1相容性好，且收缩率小。
在另一些示例中，参阅图1，壳体1的材质为ABS材料。盖板3为复合结构，包括ABS材料层、玻璃纤维层及聚碳酸酯层。
示例的，盖板3的ABS材料层、玻璃纤维层及聚碳酸酯层的设置方式包括但不限于层叠设置、往复交叉设置及混合设置。
示例的，盖板3的ABS材料、玻璃纤维及聚碳酸酯的含量比例不同，相差5％～30％。
具体的，盖板3包括ABS材料、玻璃纤维及聚碳酸酯，即与ABS材料的壳体1相容性好，又具有较小的收缩率，有利于使盖板3与壳体1之间形成良好的连接。
在另一些示例中，参阅图1，壳体1的材质为ABS材料。盖板3为复合结构，包括玻璃纤维层与聚碳酸酯层。
示例的，盖板3的玻璃纤维层与聚碳酸酯层的设置方式包括但不限于层叠设置、往复交叉设置及混合设置。
示例的，盖板3的玻璃纤维与聚碳酸酯的含量比例不同，相差5％～30％。
具体的，盖板3包括玻璃纤维与聚碳酸酯。玻璃纤维绝缘性好、耐热性强、抗腐蚀性好、机械强度高。聚碳酸酯具高强度及弹性系数、高冲击强度、耐疲劳性佳、尺寸稳定性良好、蠕变也小，弥补了玻璃纤维性脆，耐磨性较差的缺点。盖板3的材质包括玻璃纤维与聚碳酸酯，既与ABS材料的壳体1相容性好，又具有较小的收缩率。
在另一些示例中，参阅图1，壳体3的材质为ABS材料。盖板3为复合结构，包括聚酰胺层与玻璃纤维层。
示例的，盖板3的聚酰胺层与玻璃纤维层的设置方式包括但不限于层叠设置、往复交叉设置及混合设置。
示例的，盖板3的聚酰胺与玻璃纤维的含量比例不同，相差5％～30％。
具体的，盖板3包括聚酰胺和玻璃纤维。聚酰胺俗称尼龙，具有强韧、耐磨、自润滑、使用温度范围宽的优点，且成本低，能够弥补玻璃纤维性脆、耐磨性较差的缺点。盖板3的材质包括聚酰胺和玻璃纤维，既能够与ABS材料的壳体1具有较好的相容性，又能够降低收缩率。
本实施例壳体1与盖板3的材质不相同，降低了对盖板3材料的限制。
在一些实施例中，如图1～3所示，风道11包括相邻设置的第一通道111和第二通道112。出风口12连通于第一通道111。让位口13由第一通道111的靠近出风口12的一侧延伸至第二通道112的远离出风口12的一侧。
在一些示例中，如图1～3所示，第一通道111和第二通道112分别用于容纳一个滚刷且相互连通。如此设置，结构更加合理，有利于空气在风道11内的流通。
本实施例的让位口13由第一通道111的靠近出风口12的一侧延伸至第二通道112的远离出风口12的一侧，能够为风嘴2的脱模提供足够的空间，避免发生干涉。
第二方面，本实施例还提供了一种清洁设备。本实施例的清洁设备包括：设备本体、至少一个如上的滚刷支架及至少一个滚刷。滚刷支架设置于设备本体上。如滚刷的数量有多个，那么该多个滚刷可同时设置于该滚刷支架上。
可以理解的是，本实施例的清洁设备可以为扫地机器人、扫拖一体机或满足要求的其他清洁设备。
在一些示例中，滚刷包括支撑部件及设置于支撑部件外面的清洁部件组成，支撑部件可以采用高强度的支撑材料做成，例如金属管材、硬塑料等，清洁部件由具有较好清洁效果的材料做成，例如发泡橡胶、泡沫、无纺布、棉布、绒布等材料。如此设置，既能提高滚刷整体的结构强度，又能具有好的清洁能力。
在一些示例中，清洁设备还包括风机装置及尘盒，风机装置与滚刷支架上的风嘴连接，每对滚刷设置于一个滚刷支架且与地面具有一定干涉，滚刷能够将地面上的垃圾扫起并卷带到风道中，然后被风机装置产生并经过尘盒装置的有吸力的气体吸入尘盒装置内，以将垃圾收集在尘盒装置中。
可以理解的是，清洁设备还可以包括：驱动系统、感知系统、控制模块、能源系统和人机交互系统等。上述各个系统相互协调配合，使清洁设备能够自主移动以实现清洁功能。清洁设备中构成上述各系统的功能元件等集成地设置在设备主体内。
本实施例中所提供的清洁设备，具备上述实施例中的滚刷支架，因此具有更好的清洁性能，且不易积灰，便于日常的维护和清洁。
本领域的技术人员容易理解的是，在不冲突的前提下，上述各有利方式可以自由地组合、叠加。
以上仅为本申请的较佳实施例而已，并不用以限制本申请，凡在本申请的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本申请的保护范围之内。以上仅是本申请的优选实施方式，应当指出，对于本技术领域的普通技术人员来说，在不脱离本申请技术原理的前提下，还可以做出若干改进和变型，这些改进和变型也应视为本申请的保护范围。
