如图1至图4所示，本实用新型实施例中提供的一种脖带风扇，包括用于穿戴在人体脖颈上的弧形支架1，弧形支架1内形成有通风道2，通风道2沿弧形支架1的长度方向设置，弧形支架1上设有第一出风口3和第一进风口4，第一出风口3沿弧形支架1的长度方向设置并与通风道2连通，第一进风口4与通风道2连通，弧形支架1内设有第一风扇10，第一风扇10由电机驱动进行旋转而产生风，第一风扇10与第一进风口4对应设置，第一风扇10用于将外部气流通过第一进风口4引入通风道2内，并通过第一出风口3排出。
弧形支架1包括底面11，与底面11相对的顶面12，以及连接于底面11和顶面12之间的第一侧面13和第二侧面14，第一侧面13为靠近脖颈的一侧面，第二侧面14为背离脖颈的一侧面。在本实施例中，为了使第一风扇10产生的风更好的对准用户的脖颈方向排出，所以将第一出风口3设置于弧形支架1的底面11、顶面12和/或第一侧面13，以实现对脖颈部位进行吹风，从而防止与脖颈接触部位积汗。
在本实施例中，第一出风口3包括多个出风孔31，多个出风孔31沿弧形支架1的长度方向间隔设置，位于弧形支架1的顶面12上，顶面12为朝向用户的脖颈方向，外部气流由第一风扇10从第一进风口4抽入，从多个出风孔31排出，以达到对颈部散热的目的。出风孔31也可以设置于顶面12和第一侧面13，具体地，出风孔31由顶面12延伸至第一侧面13或分别在顶面12和第一顶面13开设出风孔31；出风孔31还可以设置在弧形支架1与肩部接触的底面11，以实现对肩部进行吹风。出风孔31可以为条形孔或圆 形孔等，在此对出风孔31的形状不做限制。
或者第一出风口3包括一个出风孔31，出风孔31沿弧形支架1的长度方向延伸设置，出风孔31为长条形孔，即，出风孔31的孔径由弧形支架1的一端延伸至另一端。
优选地，弧形支架1内设有相互电性连接的控制器、检测元件(图未示)、温度调节装置5、电池6及开关7。具体地，温度调节装置5为半导体，半导体用于给通风道2内的空气制冷或制热。其中，半导体包括制冷端和制热端，通过改变半导体两端电压的极性实现制冷和制热模式的转换，控制器用于控制半导体制冷制热的温度，检测元件用于检测通风道2内的空气温度，将检测信号发送至控制器，从而通过控制器控制温度调节装置5调节通风道2内的空气温度，当检测到温度大于或小于预设阈值时，控制器自动调节半导体制冷制热的温度，从而调节通风道2内空气的温度。
电池6与第一风扇10电性连接，通过操作开关7，发送操控信号给控制器，通过控制器控制第一风扇10及温度调节装置5的工作状态。具体地，开关7用于调节温度调节装置5和第一风扇10同时运行，或者只运行温度调节装置5和第一风扇10中的一种。电池6为内置于弧形支架1的充电式电池6或一次性电池6，开关7设置于弧形支架1的外壁上。优选地，弧形支架1内还设有电池隔热片60，电池隔热片60包覆在电池6外侧，用于隔绝电池6的热量，防止电池6热量传递给颈部。
在一些其他实施例中，温度调节装置5还可以为发热片，发热片用于给通风道2内的空气加热，当空气通过第一风扇10从第一进风口4进入通风道2，经过加热片的升温变成热空气，从而将热空气带出，达到给颈部制暖的效果，适合寒冷天气的使用。发热片可以是翅形片，两个发热片形成一风道，空气可以从风道经过。
值得一提的是，用户可以选择性的开启或关闭温度调节装置5，关闭时，温度调节装置5不接入电路，仅实现第一风扇10的吹风功能。
在本实施例中，弧形支架1包括相互连通的第一环形部15和第二环形部16，第一环形部15具有第一连接端151和第一自由端152，第二环形部16具有第二连接端161和第二自由端162，该第一连接端151与该第二连接端161抵靠，且该第一连接端151与该第二连接端161之间设有铰接结构17，该第一环形部15和该第二环形部16通过该铰接结构17可转动的连接。
当用户需要佩戴或取下脖带风扇时，通过第一连接端151和第二连接端161之间的铰接结构17，可以使第一环形部15和第二环形部16以该铰接结构17为转动点相对的转动，从而扩大第一自由端152和第二自由端162之间的距离，用户方便佩戴与取下；当用户佩戴好脖带风扇时，第一连接端151和第二连接端161相互抵靠，以形成围绕着脖颈的环形结构。
优选地，在第一连接端151与第二连接端161的端面之间还可以设有磁铁，通过磁铁的吸附功能，第一环形部15和第二环形部16实现更好的连接定位。在其他实施例中，弧形支架1也可以由具有弹性回复力的材料制成，从而能够通过把持弧形支架1的两端使其张开而进行戴用。
具体地，第一连接端151上具有连接孔171，第二连接端161上具有连接轴172，第一连接端151与第二连接端161抵靠，且第一环形部15和第二环形部16通过连接孔171与连接轴172配合实现可转动的铰接。
在本实施例中，第一风扇10的数量为两个，与第一风扇10对应的第一进风口4为两个，两个第一风扇10分别设置于第一环形部15和第二环形部16内，但不以此为限。具体地，两个第一风扇10分别位于靠近第一环形部15的第一自由端152，和靠近第二环形部16的第二自由端162。
实施例二
本实施例部分与实施例一相同，相同部分在此不再赘述，不同之处在于：如图5至图8所示，弧形支架1上还设有第二出风口8和第二进风口9，第二进风口9与通风道2连通，弧形支架1内还设有第二风扇20。第二风扇20的数量也可以为两个，两个第二风扇20分别靠近第一环形部15的第一自由 端152，和靠近第二环形部16的第二自由端162设置，且位于第一风扇10旁，并相对于第一风扇10更靠近弧形支架1的端部，其中，第二风扇20与第二进风口9对应设置，可以理解的，第二进风口9与第一进风口4相邻设置，但不以此为限。
在本实施例中，第二进风口9和第二出风口8位于弧形支架1相对的两侧，且同轴设置，第二风扇20设置在第二进风口9与第二出风口8之间，第二风扇20与电池6电性连接。具体地，第二出风口8设置于弧形支架1的第一侧面13，第二进风口9设置于弧形支架1的第二侧面14，以使第二风扇20将外部气流通过第二进风口9引入通风道2内，并通过第二出风口8排出，实现对脸部的吹风。优选地，为了使第一出风口3和第二出风口8所排出的风风力充足，可以在第一风扇10和第二风扇20之间设置挡板30，以隔绝两个风扇分别产生的风力，即，第一风扇10的风由第一出风口3排出，第二风扇20的风由第二出风口8排出，提高了第一风扇10和第二风扇20产生的风的利用率。
实施例三
本实施例部分与实施例二相同，相同部分在此不再赘述，不同之处在于：如图9所示，第一环形部15和第二环形部16的第一自由端152和第二自由端162上开设有通孔18，通孔18与通风道2连通，第二风扇20设置于通孔18内，在通孔18的内壁上设有角度调节部21，角度调节部21与第二风扇20连接，角度调节部21用于调节第二风扇20的方向。
如图9，图10所示，该角度调节部21可以采用经过热处理定型而且具有伸缩性能的金属线，金属线呈螺旋状收纳于弧形支架1内，第二风扇20可以通过螺旋状的金属线从通孔18内伸出或缩回。当第二风扇20需要伸出使用时，拉动第二风扇20带动金属线伸出即可，当第二风扇20需回缩进弧形支架1内使用时，将第二风扇20推入通孔18，金属线即可回缩至螺旋状的收纳状态。其中，金属线可以进行弯折或弯曲，第二风扇20可以通过调节金 属线的弯曲角度，从而实现调节第二风扇20的吹风方向，该方向可以为左、右、上、下方向。
实施例四
本实施例部分与实施例二相同，相同部分在此不再赘述，不同之处在于：如图11所示，环形支架1为侧面开孔的形式。其中，在环形支架1设有连通第一侧面13与第二侧面14的通孔18，第二风扇20设置于通孔18内，在通孔18的内壁设有角度调节部21，该角度调节部21用于调节第二风扇的方向。
具体地，角度调节部21为转轴，转轴连接于第二风扇20与通孔18的内壁之间，可以通过调整转轴的转动方向进而调节第二风扇20的旋转方向。可选地，角度调节部21还可以为球头，第二风扇20通过球头实现各方位的转动。
