AI Technical Summary
负离子模块通常包括底座、安装于底座的负离子发生器以及盖设于底座的盖板,现有技术中,盖板和底座通常通过螺钉或卡扣连接,螺钉连接的装配工序繁琐,生产效率低,且需要额外的螺丝零件,增加了材料成本和仓储管理成本;卡扣连接存在较大的装配间隙,导致盖板与底座结合后容易发生晃动或错位,并且卡扣结构的强度和耐久性有限,多次拆装后容易发生磨损或断裂,导致连接失效
[0014]本实用新型负离子模块的技术方案中,解决了现有负离子模块中盖板与底座连接方式存在的装配工序繁琐、材料成本高、连接结构易松动或磨损的问题。采用限位凸台和限位件的直接配合,替代了传统的螺钉或卡扣连接,简化了装配步骤,无需使用额外的连接件,降低了材料成本和仓储管理成本。限位凸台与限位件的机械配合提高了连接结构的耐久性和稳定性,避免了多次拆装后的磨损或断裂问题。同时,这种设计通过物理限位约束上盖与底座之间的相对位移,有效防止了装配后的晃动或错位,提高了模块的整体稳定性和密封性能。
