The invention relates to the related technical field of alcohol concentration detection, and discloses a vehicle-mounted alcohol concentration detection device, through the arrangement of a miniature interdigital electrode plate and a miniature electric heating plate, the miniature interdigital electrode plate can emit micro current to stimulate the palm of a human body and force sweat gland sweating, so that the regulation and control of sweating of the human body are realized, and the detection effect of the vehicle-mounted alcohol concentration detection device is improved. The sweat alcohol sensor can conveniently detect the alcohol content in sweat, meanwhile, the temperature of the ceramic substrate can be increased through the micro electric heating piece, the micro electric heating piece can be conveniently matched with electric stimulation of the micro interdigital electrode piece, the sweating inducing efficiency is improved, meanwhile, redundant sweat can be evaporated, slipping is prevented, and the mastering degree of a driver on a steering wheel is improved; meanwhile, evaporated alcohol can be sucked in and detected again through the alcohol gas sensor, and the detection accuracy is improved.

    本发明涉及酒精浓度检测相关技术领域,公开了一种车载酒精浓度检测装置,通过微型叉指电极片和微型电加热片的设置,使得微型叉指电极片可以发出微小电流,对人体手心进行刺激,迫使汗腺流汗,从而实现对人体流汗的调控,便于汗液酒精传感器对汗液中的酒精含量进行检测,同时微型电加热片可以提高陶瓷基板的温度,便于与微型叉指电极片的电刺激进行配合,提高催汗效率,同时还可以将多余的汗液蒸发,防止打滑,提高驾驶员对方向盘的掌握,同时还可以将蒸发的酒精吸入并通过酒精气体传感器再次检测,提高检测准确度。
