Description

一种双涡扇环绕风安全帽 技术领域
本实用新型涉及到一种安全帽；特别是涉及一种用于带涡扇的安全帽。
背景技术
安全帽是指对人头部受坠落物及其他特定因素引起的伤害起防护作用的帽子。由帽壳、帽衬、下颊带和后箍组成。帽壳呈半球形，坚固、光滑并有一定弹性，打击物的冲击和穿刺动能主要由帽壳承受。帽壳和帽衬之间留有一定空间，可缓冲、分散瞬时冲击力，从而避免或减轻对头部的直接伤害。现有安全帽通风不好，安全帽内部温度会持续增高，人们戴着安全帽工作会很不舒适，严重的甚至会中暑，因此，会在安全帽上增加一个风扇用于降温。
现有中国专利授权公告号为CN207561432U，其公开了一种用于安全帽的风扇及其安全帽。所述用于安全帽的风扇包括风扇主体，所述风扇主体安装在安全帽的外表面，所述风扇主体底部为弯曲部，所述弯曲部设有至少一个朝下的脖子送风口。
其具有如下问题:1.现有变向涡轮风扇，绑在安全帽外壳上，由于改变出风方向，风力损失大，送达头部的风量微弱，达不到降温效果，而且，安全帽绑涡轮，增大安全帽体积和重量，不规则凸起的外接涡扇影响作业安全，降低工人作业效率。
2.变向涡扇和安全帽并不是一个独立产品，实用性和便利性达不到要求。
发明内容
本实用新型提供本实用新型提供一种有效降温、无外接设备、安全可靠、风力从头部垂直向下形成环形风的内置双涡扇安全帽。
一种双涡扇环绕风安全帽，包括用于控制涡扇的开关、电源和连接电线，安全帽左右两侧沿帽沿各设有第三空腔和第四空腔；所述第三空腔和第四空腔呈流线状的长条体，空腔内安装有涡扇；空腔盖板上有突起的引风环条；引风环条和腔壳构成风道，风道的下沿向下设有多个出风口。
进一步地，上述风道由从所述涡扇方向为从大渐变到小。
进一步地，包括第一空腔和第二空腔，第一空腔设置于所述安全帽的帽檐上，第一空腔内安装有涡扇控制电路板和可充电电路板，用于控制涡扇开关和 风力档位，帽檐下方设置涡扇开关/风力档位按钮；第二空腔内设置于帽壳后部且内置聚合物电池，所述聚合物电池通过埋设在帽壳内的电线对所述第一空腔可充电电路板连接，所述第一空腔涡扇控制电路板与涡扇连接。
本实用新型的有益效果是:左右涡扇工作时，风力经环形送风口向左右两侧头面部和身体送风，对人体进行有效降温，在全球升温的大环境下，有效改善工人的工作环境。[0011]工人在使用时，在防暑降温效果下，安全帽体没有外接设备和多余开口，不影响工作效率和安全帽的安全属性，内置涡扇的宽度只有10-20mm，不影响安全帽的内空安全要求，也不影响安全帽外观构造，按此设计方案生产的安全帽在标准范围之内，完全符合安全标准，因此实用性强。
