优选地,隔板48远离导引部52的一端朝向第二本体16的外壁一侧弯折延伸形成定位部,定位部上设有过线孔76,过线孔76可供收容空间50内的导线穿过定位,避免支架12内线体杂绕。
第二本体16对应风机18的内侧壁和外侧壁上均设有开孔78,开孔78内安装有保护片80,保护片80上设有多个网孔82,以供风机18从外部吸入空气,通过在开孔78内安装保护片80,保护片80上设置多个小圆形网孔82,以供风机从外部吸入空气,由于每个网孔82尺寸比较小,因此能够有效降低用户的头发绞入风机内的几率,增加产品的使用安全性。在所示的实施例中,多个网孔82呈环形分布于保护片80上,多个网孔82排布呈多圈环形,包括外环孔、内环孔及位于外环孔与内环孔之间的至少一圈中间孔,本实施例中,外环孔与内环孔之间设置一圈中间孔。优选地,中间孔的孔径小于外环孔的孔径,内环孔的孔径小于中间孔的孔径,如此设计,能够进一步有效防止用户头发卷入风机18内。
进一步地,保护片80为金属片,且其周缘设有折边84,折边84自保护片80的周缘朝开孔78内弯折形成,开孔78的周缘设有抵挡部86,抵挡部86自开孔78的内侧缘向内延伸形成用于挡止折边84防止所述保护片80过度装入所述开孔78内,折边84上还延伸有卡持部88,抵挡部86上设有缺口90,卡持部88卡入缺口90内,从而实现保护片80相对第二本体16稳固连接。通过金属的保护片80的设置,能够有效增加第二本体16侧壁对应风机18部分的结构强度,且多个网孔82的结构排布能够有效防止用户头发绞入风机18,在其他实施例中,保护片180也可以采用其他材料制成。
进一步地,卡持部88的末端设有扩大部,当卡持部88卡入缺口90内后,扩大部可弯折勾持在缺口90侧缘进行定位,进一步增强保护片80的连接稳固性。
在所示的实施例中,开孔78内设有安装架92,安装架92包括中心部94及连接于中心部94周边的若干连接条96,连接条96的末端与开孔78的侧壁连接,相邻两个连接条96之间设有进风口43,且连接条96对应网孔82设有通孔98,以防止影响风机18进风,通过安装架92的设置,进一步增加保护片80在开孔78内的安装稳定性,当开孔78内设有安装架92时,也可以通过安装架92抵持保护片80而防止保护片80过度装入开孔78内,如果开孔78内没有安装架92,则可通过所述抵挡部86与折边84的配合实现防止保护片80过度装入开孔78内。
由于两个第二本体16与第一本体14之间的转动连接结构相同,下文仅以一个第二本体16与第一本体14的转动连接结构为例进行说明。
转动连接结构包括第一连接件100和第二连接件102,第一连接件100和第二连接件102的一端通过转轴和轴孔的枢转结构相互配合以实现转动连接,另一端分别与第一本体14和第二本体16固定连接,例如通过螺丝固定连接或者卡扣连接,从而使得第二本体16可相对第一本体14左右转动。具体地,第一连接件100包括第一固定部和连接于第一固定部一端并间隔设置的两个第一枢转部,第一枢转部上设有轴孔,第二连接件102包括第二固定部和连接于第二固定部一端的第二枢转部,第二枢转部上设有轴孔。安装时,第一固定部伸入第一本体14的端部内固定,第二固定部伸入第二本体16的端部内固定,第二枢转部伸入两个第一枢转部之间,转轴插设于轴孔,从而实现转动连接。
优选地,第一连接件100或第二连接件102上设有限位件,限位件用于防止第二本体16相对第一本体14过度转动。在所示的实施例中,限位件为设置在第一枢转部外周壁上的凸块104,当第二本体16相对第一本体14转动至预设角度时,凸块104因抵靠第二固定部而停止转动,从而实现对第二本体16的限位。当然在其他实施例中,限位件也可以为设置在第二枢转部外周壁上的凸块104,当第二本体16相对第一本体14转动至预设角度时,凸块104因抵靠第一固定部而停止转动,从而实现对第二本体16的限位。
优选地,转动连接结构还包括阻尼件,阻尼件用于增大第二本体16相对第一本体14转动的摩擦阻力,并使得第二本体16可相对第一本体14稳固停留在任意转动位置,避免第二本体16在非外力作用下相对第一本体14转动。在所示的实施例中,阻尼件为阻尼圈106,阻尼圈106设置两个,两个阻尼圈106分别夹设在第二枢转部与两个第一枢转部之间。
由于第一连接件100和第二连接件102的连接部分是露出于第一本体14和第二本体16之外的,为了避免影响产品美观,在所示的实施例中,在转动连接结构外套设有硅胶套108,硅胶套108的两端分别设有固定段,硅胶套108两端的固定段与中间部分可以是一体延伸形成或通过套啤连接,固定段上设有螺孔,两个固定段分别包覆在第一连接件100和第二连接件102的固定部外部并利用螺丝分别固定在第一本体14和第二本体16内,硅胶套108的中间部分套设在第一连接件100和第二连接件102的连接部分外部。由于硅胶套108为软性材质,会随着转动连接结构的转动而发生弹性形变,因而不会影响转动连接结构的转动。硅胶套108两端的外表面可设置为与第一本体14和第二本体16的外表面平滑过渡,增加产品美观度。
可选地,第二本体16包括相互组装连接的第二外壳16a和第二内壳16b,第二外壳16a与第二内壳16b之间可以通过卡扣、螺接等方式可拆卸固定连接,以方便用户拆卸。风道44形成于第二外壳16a和第二内壳16b之间,导风件56设于第二外壳16a和第二内壳16b其中之一的内壁上。本实施例中,导风件56自第二内壳16b一体延伸形成为一个整体。
如图6-图7所示,为本申请第二实施例的示意图,与上述实施例的区别在于,本实施例中,导风件56是组装固定在第二本体16的内侧壁上,参阅图7,导风件56包括两部分组成,一部分是一体连接在第二内壳16b的内侧壁上,即远离风机18的部分是一体连接在第二内壳16b的内侧壁,另一部分是组装固定在第二内壳16b的内侧壁,具体地,第二内壳16b的内侧壁上设有定位柱161,该另一部分的导风件56上设有定位孔561,定位柱161与定位孔561配合将该另一部分的导风件56固定在第二内壳16b的内侧壁上;且一体连接在第二内壳16b内侧壁上的该一部分的导风件56在靠近风机18的一端上设有两个L形卡持槽562,组装固定在第二内壳16b内侧壁上的该另一部分的导风件56的末端对应设有两个L形卡持部563,通过将两个L形卡持部563分别卡持在两个L形卡持槽562内,从而进一步增加导风件56的组装稳定性。另外,本实施例中,连接条96是呈顺着风机18旋转方向弯曲的弧形,更有利于减小进风阻力,降低产品噪音。为了在转动连接结构转动时,硅胶套108更容易实现对应弯折,本实施例中还在硅胶套的中间部分对应设置折痕,例如凹槽,从而使得转动连接结构转动时,硅胶套108更容易对应实现弯折变形以不影响转动连接结构的转动。本实施例中第一本体14及制冷调整装置等其他部分的结构与上述实施例相同,故在此不再赘述。

进一步地,调温组件还可以包括蜂鸣器,蜂鸣器与电路板电连接,使得按压操作控制按键时具有声音,从而方便用户感知按键的有效操作,例如,长按控制按键蜂鸣器发生长叫,短按控制按键蜂鸣器发生短叫。

更具体地,第一连接件38包括第一连接部46及连接于第一连接部46靠近第二连接件40一端并间隔设置的两个枢接部48,齿部42设置在枢接部48靠近第二连接件40一端的端面上。优选地,枢接部48靠近第二连接件40一端的端面设置成凸出的弧形面,齿部42包括沿转动方向间隔排列的若干齿条,相邻的两个齿条之间形成齿槽。两个枢接部48之间形成枢接槽,枢接部48上设有第一轴孔50。第二连接件40包括第二连接部52及连接于第二连接部52靠近第一连接件38一端的转动部54,转动部54上设有第二轴孔58。优选地,转动部54的两侧设有转轴56,例如转轴56贯穿转动部54设置,第二轴孔58贯穿转轴56设置。凸起部44设置在第二连接部52靠近第一连接件38一端的端面上,优选地,凸起部44为沿转动连接结构的轴向方向延伸的凸条。

在所示的实施例中,转动连接结构的外部包覆有保护套,可防止用户头发绞入转轴处。具体地,保护套包括软胶套62及固定在软胶套62两端的硬胶件64,两个硬胶件64分别包覆在第一连接件38和第二连接件40的外部。通过在软胶套62的两端进一步设置(例如通过注塑成型)硬胶件64,能够更有效地防止软胶套62发生变形时,两端与第一本体12或第二本体14的端部之间出现缝隙,甚至脱离开,而且使得产品外形更美观。
第一连接部46和第二连接部52上分别设有第一螺孔66,两个硬胶件64分别对应两个连接部上的第一螺孔66设有第二螺孔68,第一本体12和第二本体14的内壁上分别设有螺柱70。安装时,第一连接部46远离第二连接件40的一端伸入第一本体12的端部内,第二连接部52远离第一连接件38的一端伸入第二本体14的端部内,利用螺钉穿过对应的第一螺孔66和第二螺孔68并螺纹连接至螺柱70,使得第一连接件38和对应的硬胶件64通过螺钉穿入第一螺孔66、第二螺孔68和螺柱70与第一本体12固定连接,第二连接件40和对应的硬胶件64通过螺钉穿入第一螺孔66、第二螺孔68和螺柱70与第二本体14固定连接。

如图14-图18所示,本申请第四实施例提供一种挂脖调温装置,可以穿戴于人体颈部以方便用户随身携带,随时随地对人体,特别是人体颈部与面部调温。本实施例的挂脖调温装置整体大致呈U形,由两个送风模块10和设置于两个送风模块10之间的调温模块30构成。佩戴于脖颈上时,调温模块30位于人体后颈处、两个送风模块10分别位于左右侧颈处,从而可以全方位地对人体脖颈、头部等进行调温,提升用户的舒适度。在一些实施例中,本申请挂脖调温装置也可以省略调温模块30。
本实施例中,送风模块10和调温模块30可转动地连接以便调整两者之间的角度,既方便调整本申请挂脖调温装置使用时的形态,特别是调整送风模块10的出风角度与出风距离,也方便本申请挂脖调温装置的穿戴与存放。较佳地,送风模块10和调温模块30相连接的位置上套设有保护套20,使得整个产品的外形光滑、美观,保护套20可采用软胶材料制成,例如硅胶。较佳地,保护套20上形成有环形凹槽22,使得送风模块10和调温模块30相对转动时保护套20能够很容易地对应发生变形,方便用户转动,本实施例中个,环形凹槽22是设置在保护套20的外表面上,在其他实施例中,环形凹槽22也可以是设置在保护套20的内表面上。在其它实施例中,送风模块10和调温模块30也可以是固定连接等,不以具体实施例为限。
请同时参阅图16与图17,送风模块10包括第二本体12和设置于第二本体12内的风机14、电路板16以及电池模块18,其中,风机14、电路板16和电池模块18电性连接。
沿挂脖调温装置的长度方向,挂脖调温装置的宽度由其末端向中央逐渐减小,如此挂脖调温装置的中央(即调温模块30)与脖颈相接触的部位相对较窄,可以增加佩戴的舒适性;挂脖调温装置的两端(即送风模块10)相对较宽,可以配置更大尺寸的风机14,提高出风量。相应地,第二本体12呈渐缩结构,其内部空间的宽度由其外侧端(即远离调温模块30的一端)向内侧端(即连接调温模块30的一端)逐渐减小。风机14优选地为离心风机,设置于第二本体12的外侧端,即宽度最大位置处。
本实施例中,第二本体12由可拆卸相连的第一内壳12a和第一外壳12b构成,其中,第一内壳12a朝向脖颈、第一外壳12b背向脖颈。第一内壳12a与第一外壳12b之间设置有分隔件13,分隔件13呈薄板状、沿第二本体12的长度方向延伸。图示实施例中,分隔件13朝向风机14的一侧端折弯至与第一外壳12b连接。第一内壳12a与分隔件13之间形成第一腔室120,用于设置风机14并构成风机14的风道;第一外壳12b与分隔件13之间形成第二腔室122,用于设置电路板16和电池模块18。
通过分隔件13的设置,将风机14的风道与电池模块18等隔开,即避免电池模块18等影响气流的流动,也保证了电池模块18等的电气安全。另外,分隔件13的设置使得气流在第二本体12内实际流动的风道(即第一腔室120)相对于第二本体12的内部空间减小约一半,可以有效提高气流的流速,进一步提高出风量。再另外,由于第二本体12呈渐缩状,第一腔室120、第二腔室122呈类似的渐缩状结构,如此沿气流的流向风道的尺寸逐渐减小,可以对气流形成节流加速效果。
第二本体12对应风机14形成有进风口124、对应风道形成有出风口126,气流在风机14的作用下由进风口124进入第二本体12并沿第一腔室120流动,加速后由出风口126向外吹出。图示实施例中,进风口124形成于第二本体12的内、外侧壁,即分别形成于第一内壳12a与第一外壳12b上;出风口126形成于第二本体12的上、下侧壁,即分别形成于第一内壳12a的上缘与下缘,如此上下两侧同时出风,部分气流向上吹向侧颈与面部、部分气流向下吹向侧颈与前胸。
较佳地,在第二本体12的长度方向上,出风口126的范围覆盖整个风道,使得出风范围更宽。较佳地,第一外壳12b的进风口124上罩设有金属保护盖128,保护盖128上形成有若干网孔,确保外部空气可以通过网孔进入第二本体12的同时,防止杂物如头发等掉入第二本体12,影响风机14的使用安全,同时也使得整个产品的外形更为美观。应当理解地,可以仅在第二本体12的内侧壁或外侧壁设置进风口124,也可以仅在第二本体12的上侧壁或下侧壁设置出风口126。
与第二本体12的渐缩结构相对应,分隔件13的宽度沿第二本体12的长度方向朝向其内侧端逐渐减小。本实施例中,第二本体12上下两侧出风,分隔件13靠近风机14的一端的上下侧缘分别朝向第一腔室120延伸有导风部130。导风部130呈弧形结构,用于导引风机14的气流进入第一腔室120。当第二本体12单侧出风时,分隔件13可以仅在对应第二本体12出风的一侧的边缘延伸有导风部130。分隔件13靠近风机14的一端的上下侧缘分别朝向第二腔室122延伸有挡板132,两个挡板132之间形成安装腔134。电池模块18固定于安装腔134内,相对地靠近第二本体12的外侧端;电路板16通过螺钉等固定于分隔件13上,相对地靠近第二本体12的内侧端设置。
沿第二本体12的长度方向,所述风机14、电池模块18、电路板16顺序设置,风机14位于第二本体12的外侧端、电池模块18紧邻风机14设置。如此电池模块18尽可能地靠近第二本体12的外侧端,可以有更大的安装空间,电池模块18可以有更大的尺寸、更大的容量,确保有足够的续航能力;电路板16可以采用窄条结构,与第二本体12的内部空间相适配。根据第二本体12的渐缩结构安排风机14、电池模块18、电路板16等,有效利用第二本体12的内部空间,使得整体结构更为紧凑合理。
请同时参阅图18,电池模块18包括电池180和与电池180电性连接的保护板182。电池180为方块状结构,优选地为聚合物充电电池。对应地,电路板16上设置有充电接口160,用于连接外部电源对电池180充电。保护板182为长条状并设置于电池180的侧端,本实施例中,保护板182位于电池180的外侧端,即更靠近风机14,当然在其他实施例中个,保护板182也可以是位于电池的内侧端或上侧端或下侧端,保护板182与电池180的正负电极通过两个金属导电片184连接。保护板182上设置有保护芯片186,对电池180形成过放保护、过充保护、短路保护、过电流保护等,确保电池180的使用安全与使用寿命。另外,保护板182上设置有正负引线188,用于与电路板16连接。
图示实施例中,每一送风模块10的第二腔室122内设置一电池模块18对该送风模块10的风机14供电,也就是说每个风机14单独供电。应当理解地,也可以仅设置一个电池模块18同时对两个风机14供电。较佳地,其中一个所述第二本体12上设置有控制按键40用于控制风机14的启停,控制按键40正对电路板16所在位置并与电路板16电性连接,具体地,本申请实施例两个送风模块10是通过一个控制按键40控制,因此只在其中一个第二本体12内设有与开关按键40连接的电路板16,当然在其他实施例中,如果要实现两个送风模块10分别单独控制,可以分别在两个第二本体12内设置电路板16及与电路板电连接的控制按键40。较佳地,电路板16上还设置有LED灯162,第二本体12在对应LED灯162的位置上设置有透光孔129。所述LED灯162可以作为挂脖调温装置的工作状态指示灯、黑暗环境下的照明灯等。
如图16所示,调温模块30包括第一本体32、设置于第一本体32内的调温片34、导热件36、散热件38以及散热风扇39。第一本体32和第二本体12可定义为挂脖调温装置的支架。
调温片34为半导体器件,通过电路板16与电池模块18电性连接。根据半导体的热电效应,调温片34通电时其相对两侧分别形成冷端与热端。导热件36与调温片34的冷端贴设以将冷量向传外递、散热件38与调温片34的热端贴设以将热量向传外递。较佳地,第一本体32的内侧壁突出形成有凸部320,导热件36连接于凸部320上并伸出第一本体32的内侧壁。本申请挂脖调温装置在使用时,导热件36取代第一本体32的内侧壁而与人体后颈相贴,将调温片34产生的冷量直接传导至后颈。
散热件38和散热风扇39沿第一本体32的长度方向顺序排布,其中散热件38包括若干散热片,散热片可以是导热性良好铝、铜等金属材料或其合金制成,可以吸收调温片34的热量并散发至周围空气中。相邻的散热片间形成散热槽380,散热槽380沿第一本体32的长度方向延伸,正对散热风扇39的出风侧设置。较佳地,散热件38的上下两侧设置有隔热片382,隔热片382将散热件38与第一本体32的上下侧壁间隔开,避免散热件38的热量传递至第一本体32而影响本申请挂脖调温装置佩戴的舒适性。
散热风扇39优选地为离心风扇,第一本体32的外侧壁对应散热风扇39形成有进气孔322、对应散热件38形成有散热孔324,外部冷空气在散热风扇39的作用下由进气孔322进入第一本体32、与散热件38进行热交换后由散热孔324流出第一本体32,如此不断循环将调温片34的热量散发至外界。较佳地,第一本体32的外侧壁朝向第一本体32内延伸形成有分隔片326,分隔片326位于散热孔324与进气孔322之间,隔离吸入第一本体32的冷空气和与散热件38进行热交换之后的热空气,确保散热效果。
较佳地,所述控制按键40与调温模块30通过电路板16电性连接,以控制调温模块30的启停。电路板16上设置有控制电路分别与送风模块10的风机14、调温模块30的调温片34、散热风扇39等连接,可以通过控制按键40的按压分别控制风机14、调温片34、散热风扇39的启停。较佳地,在关闭调温模块30时,控制电路使得散热风扇39的关闭相对于调温片34的关闭有一定时间,如5-10S的延时,如此在调温片34停止工作后,散热风扇39继续工作一定时间,确保热量能够被充分散发至外界。其中,控制调温片34先停止工作,并在预设时长后控制散热风扇39停止工作的实现方式可以是,电路板16上设有主控芯片,主控芯片获取到控制调温模块30关闭的操作后,通过热电片的控制端控制调温片34停止工作,并同时开始计时,当计时到达预设时长后,再通过散热风扇的控制端控制散热风扇39停止工作。
本实施例中,第一本体32包括可拆卸地相连的第二内壳32a和第二外壳34a,其中第二内壳32a朝向脖颈、第二外壳34a背向脖颈。所述凸部320形成于第二内壳32a上,散热孔324、进气孔322、分隔片326形成于第二外壳34a上。第二本体12与第一本体32共同构成挂脖调温装置的支架,支架的末端即为第二本体12的外侧端、支架的中央即为第一本体32以及第二本体12的内侧端;第二内壳32a与第一内壳12a转动连接、共同构成所述支架的内壳,第二外壳34a与第一外壳12b转动连接共同构成所述支架的外壳。应当理解地,挂脖调温装置的支架/内壳/外壳也可以是不可拆的一体结构。
需要说明的是,本实施例中,以挂脖调温装置佩戴至人体颈部时的朝向定义内外、上下、前后、左右等方向。具体地,所涉及的支架/第二本体12/第一本体32朝向脖颈的一侧为内侧、背向脖颈的一侧为外侧、朝向头部的一侧为上侧、背向头部的一侧为下侧;支架/第二本体12/第一本体32的长度是指环绕脖颈的方向上的长度,支架/第二本体12/第一本体32的宽度是指上下方向上的宽度,支架/第二本体12/第一本体32的厚度是指内外方向上的厚度。
综上所述,本申请挂脖调温装置用于制冷时,调温片的冷端与导热件相贴,导热件将冷量传导至脖颈,特别是后颈位置;同时,风机对颈部、面部吹风,通过风机的冷风与调温片的冷量的双重作用,形成良好的散热降温效果。应当理解地,本申请挂脖调温装置也可以用于制热取暖,此时改变调温片的电流方向使其热端与导热件相贴,导热件将热量传导至后颈取暖。制热取暖时,可以控制风机关闭,只通过调温片和导热件制热取暖,或者在其他实施例中,也可以是在风机的气流路径上可以设置发热元件,如电阻丝、电热片等,使得最终吹出的气流为暖风,如此可以通过风机的暖风与调温片的热量的双重作用,形成良好的取暖效果。
本文所描述的概念在不偏离其精神和特性的情况下可以实施成其它形式。所公开的具体实施例应被视为例示性而不是限制性的。因此,本申请的范围是由所附的权利要求,而不是根据之前的这些描述进行确定。在权利要求的字面意义及等同范围内的任何改变都应属于这些权利要求的范围。
