Description

便携风扇 技术领域
本申请涉及风扇技术领域,具体涉及一种安全的含有负离子的便携风扇。
背景技术
随着人们生活水平的提升,人们对空气质量的要求也逐步提升,希望身处环境的空气能够得到净化。然而,目前市面上的便携式风扇大多只有吹风的功能,并不能对空气净化。部分便携式风扇设有负离子模组可产生负离子,利用负离子的杀菌消毒功能对空气进行净化。
但现有的负离子模组直接通过电池提供电压给负离子发生器,使负离子发生器产生净化空气的负离子。当电池提供高电压给负离子发生器时,容易产生漏电、静电现象,当生物或物体靠近时容易产生触电的安全问题。
发明内容
鉴于此,本申请提供一种便携风扇,通过同时设置正极释放部和负极释放部,避免了与人体发生短路而产生微电流的情况发生,产品安全性能更高。
本申请提供一种便携风扇,包括:壳体,设有依次连通的进风口、容纳腔、风道和出风口,所述壳体包括设置所述出风口的第一侧壁;风扇组件,收容于所述容纳腔,用于将风从所述进风口经由所述风道吹向所述出风口;负离子模块,设于所述壳体,所述负离子模块包括负离子发生器、正极释放部和负极释放部,当所述负离子发生器工作时,所述正极释放部和所述负极释放部之间放电,电离空气而产生负离子,所述负离子排出所述壳体。
与现有技术相比,本申请便携风扇具有以下有益效果:在所述便携风扇上设置所述负离子模块,具有杀菌消毒洁净空气的附加功能。并且,同时设置所述正极释放部和所述负极释放部,避免了与人体发生短路而产生微电流的情况发生,产品安全性能更高。

现有技术中,通常会在转轴12的末端设置卡簧,卡簧防止转轴从轴管中移出,卡簧用于防止叶轮脱落,本申请不设置在转轴12的末端设置卡簧,在使用时或者移动产品时,转轴12有可能从轴管11中脱落,叶轮2有可能移动,在叶轮2对应位置拆卸件4上设置止碰件21,止碰件21用来替代卡簧,用于防止叶轮2脱落。

止碰件21可以是圆柱体,也可以是正方体,只要是能够防止叶轮2脱落即可,可以预想的,也能防止碰击拆卸件4产生碰击声。

如图66至图68所示,对应两个所述夹臂13,所述便携风扇100设有两个所述支撑件2。当两个所述夹臂13枢转时,两个所述支撑件2与人体接触的位置也随之改变,但由于所述支撑件2与所述夹臂13为可转动连接,因此两个所述支撑件2还是可以分别调整为贴合人体脖颈,从而增强佩戴舒适性。
如图66至图68所示,对应每一所述风扇组件3,每一所述夹臂13设有位于所述第一侧壁11的第一进风口141和位于所述第二侧壁12的第二进风口142。所述容纳腔15位于两个所述夹臂13相连接的一端,所述支撑件2对应所述容纳腔15设置,所述支撑件2的至少部分与所述第一进风口141之间具有间隔。因此,所述便携风扇100使用时,所述支撑件2并不影响所述第一进风口141的正常进风。并且,参考图70,所述支撑件2对应所述第一进风口141还形成有通孔22,以便将所述支撑件2与人体脖颈接触产生的汗及时吸走挥发,保证用户颈部干燥清爽,提升佩戴体验。

如图73所示,为本申请便携风扇100第二实施方式的示意图。与第一实施方式的主要区 别在于:所述第二配合部21包括安装托213,所述第一配合部18包括固定于所述第一侧壁11的固定件184,以及穿过所述安装托213并与所述固定件184固定的旋转球185,所述安装托213相对所述旋转球185转动,以使所述支撑架相对所述旋转球185转动。相对第一实施方式中所述支撑架可上下转动,本实施例中的所述支撑架可球面旋转,穿戴时更加舒适。其他结构和性能与第一实施方式基本一致,在此不再赘述。

实施例8
如图76至图80所示,为本申请便携风扇100第一实施方式的示意图,所述便携风扇100包括夹臂1、风扇组件2和旋转连接结构3。所述夹臂1的数量为两个,每一所述夹臂1设有相连通的进风口11、容纳腔12、风道13和出风口14。所述风扇组件2的数量对应为两个,一个所述风扇组件2对应设于一个所述容纳腔12内,所述风扇组件2用于将所述进风口11的风经由所述风道13自所述出风口14吹出。所述旋转连接结构3包括第一铰接件31和第二铰接件32,所述第一铰接件31包括平行间隔设置的多个第一片体311,所述第二铰接件32包括平行间隔设置的多个第二片体321。
其中,所述第一铰接件31固定于一个所述夹臂1,所述第二铰接件32固定于另一个所述夹臂1,所述第一铰接件31和所述第二铰接件32相固定配合,且多个所述第一片体311和多个所述第二片体321交叉层叠,使得两个所述夹臂1可相对旋转,且停止旋转时保持旋停状态。通过设置包括多个所述第一片体311的所述第一铰接件31和多个所述第二片体321的所述第二铰接件32,多个所述第一片体311和多个所述第二片体321交叉层叠,极大地增大所述第一铰接件31和所述第二铰接件32之间的摩擦力,使得两个所述夹臂1之间旋转时随旋随停,安全性能更好。
在本实施例中,所述第一铰接件31包括五个所述第一片体311,所述第二铰接件32包括六个所述第二片体321,每个所述第一片体311与相邻的两个所述第二片体321都有一个接触面,当所述第一片体311和所述第二片体321交叉叠放时,一共有十个接触面,摩擦力是一个接触面时的十倍,因此所述旋转连接结构3连接完成后转动的摩擦力较大,以实现随旋随停。当然,所述第一片体311的数量和所述第二片体321的数量不以此为限制。
应当理解,在其他实施例中,所述夹臂1的数量还可以为三个,相邻的两个所述夹臂1之间设置所述旋转连接结构3,使得相邻的两个所述夹臂1之间可旋转,且旋转时随旋随停。
如图76至图78所示,在本实施例中,所述风扇组件2为离心式风扇,对应每一所述风扇组件2,所述夹臂1设有两个所述进风口11,双侧进风,风力更强,出风效果更好。所述便携风扇100朝向脖颈的一侧还设有支撑部,所述支撑部既能将所述便携风扇100支撑贴合于脖颈,佩戴更加舒适;还能将所述夹臂2壳体与脖颈撑开距离,使得朝向脖颈一侧的所述进风口11更好地进风。
如图78至图80所示,多个所述第一片体311的厚度相同,多个所述第二片体321的厚度相同,且多个所述第一片体311的厚度和多个所述第二片体321的厚度相同,每一所述第一片体311的厚度为1.5mm,每一所述第二片体321的厚度为1.5mm。相邻的两个所述第一片体311之间的间隔比所述第二片体321的厚度大0.01~0.3mm,在本实施例中,相邻的两个所述第一片体311之间的间隔比所述第二片体321的厚度大0.1mm,相邻的两个所述第二片体321之间的间隔比所述第一片体311的厚度大0.1mm。
如图78至图80所示,在本实施例中,还包括枢轴33,所述枢轴33穿过交叉层叠的多个所述第一片体311和多个所述第二片体321,以固定所述第一铰接件31和所述第二铰接件32。所述容纳腔12位于所述夹臂1靠近所述旋转连接结构3的一端,所述容纳腔12收容所述风扇组件2,自所述容纳腔12朝所述夹臂1的自由端的方向设有所述风道13和线路仓15,且至少一个所述线路仓15收容电池4,所述电池4对所述风扇组件2供电,两个所述风扇组件2同时运行或独立运行。
如图78至图80所示,所述第一片体311和所述第二片体321形状相同,且均为不规则多边形。将两个所述夹臂1的自由端旋转拉开时,所述第一片体311和所述第二片体321的接触面积增大,因此所述第一铰接件31和所述第二铰接件32之间的摩擦力增大。将两个所 述夹臂1的自由端旋转靠近时,所述第一片体311和所述第二片体321的接触面积减小,因此所述第一铰接件31和所述第二铰接件32之间的摩擦力减小。也就是说,将两个所述夹臂1的自由端旋转拉开时所述第一铰接件31和所述第二铰接件32之间的摩擦力,大于将两个所述夹臂1的自由端旋转靠近时所述第一铰接件31和所述第二铰接件32之间的摩擦力。也就是说,将两个所述夹臂1的自由端旋转靠近比将两个所述夹臂1的自由端旋转拉开更容易,因此两个所述夹臂1穿戴于用户脖颈时,不易滑脱脱离用户脖颈。
如图77至图80所示,应当理解,由于所述枢轴33的位置靠近所述第一片体311和所述第二片体321的自由端,且所述第一片体311和所述第二片体321相互之间没有限位结构,理论上所述第一铰接件31和所述第二铰接件32之间可以转动超过180°。但根据产品实际需求,两个夹臂1的壳体之间的间隔较小,由于两个夹臂1的壳体之间的间隔限制,两个所述夹臂1的枢转角度范围为±10°。
如图81至图82所示,为本申请便携风扇100第二实施方式中所述旋转连接结构3的示意图。与第一实施方式的主要区别在于:不设有所述枢轴33穿过所述第一片体311和所述第二片体321,而是所述第一铰接件31和所述第二铰接件32两者中的一个设有枢接部322,另一个设有枢接孔312,所述枢接部322固定于所述枢接孔312,以固定所述第一铰接件31和所述第二铰接件32。无需另外的零件,直接通过所述第一铰接件31和所述第二铰接件32本身成型所述枢接部322和所述枢接孔312,可节约安装步骤。所述枢接部322和所述枢接孔312对应设有两个,两个所述枢接部322和两个所述枢接孔312分别设于多个所述第一片体311和多个所述第二片体321的相对两侧。其余结构和性能与第一实施方式基本相同,在此不再赘述。

如图90至图92所示,在所述连接件1和所述夹臂2的安装处,所述连接件1面对所述夹臂2形成有第一配合面11,所述夹臂2面对所述连接件1形成有第二配合面22,所述第一配合面11和所述第二配合面22为相平行的两个弧面。在本实施例中,所述第二配合面22为凹曲面,所述夹臂2形成有凸部221,所述凸部221自所述第二配合面22凸出。所述第一配合面11为凸曲面,所述连接件1形成有卡槽111,所述卡槽111自所述第一配合面11凹设。枢轴13在所述第一方向X上同时贯穿连接所述凸部221和所述卡槽111,以使所述凸部221和所述卡槽111稳定枢接。其中,所述卡槽111的体积大于所述凸部221的体积,当所述凸部221插入所述卡槽111,所述枢轴13在所述第一方向X上同时贯穿连接所述凸部221和所述卡槽111时,所述卡槽111还留有空间供所述凸部221枢转,所述卡槽111内壁对所述凸部221的枢转进行限位。
在其他实施例中,也可以是所述第一配合面11为凹曲面,所述连接件1形成有所述凸部221,所述凸部221自所述第一配合面11凸出,所述第二配合面22为凸曲面,所述夹臂2形成有所述卡槽111,所述卡槽111自所述第二配合面22凹设。所述枢轴13在所述第一方向X上同样同时贯穿连接所述凸部221和所述卡槽111,以使所述凸部221和所述卡槽111稳定枢接。其中,所述卡槽111的体积大于所述凸部221的体积,所述卡槽111内壁对所述凸部221的枢转进行限位。
参考图90和图93,当两个所述凸部221枢转使得两个所述夹臂2的自由端极限靠近时,所述便携风扇100整体所占空间最小,且两个所述夹臂2之间的开口最小,便于将所述便携风扇100固定于用户脖颈,两个所述夹臂2的自由端之间的距离为:0-16mm;参考图90和图94,当两个所述凸部221枢转使得两个所述夹臂2的自由端极限远离时,两个所述夹臂2之间的开口最大,便于用户穿戴和取下所述便携风扇100,可穿戴于不同大小的脖颈,两个所述夹臂2的自由端之间的距离为:160.3-162.7mm。应当理解,两个所述夹臂2均可伴随两个所述凸部221在枢转停止时定位保持在对应位置,也就是说,所述枢轴13与所述凸部221和所述卡槽111之间具有阻尼力,所述凸部221停止枢转时,所述夹臂2整体可在该角度定位保持。而所述凸部221的枢转角度范围为±10°,所述凸部221在枢转角度范围内无极枢转,因此,两个所述夹臂2之间的距离是在极限靠近和极限远离中无极变化的。
