摘要:【中文】本发明涉及一种充气冷却反冲洗式防护服,至少包括防护服、风扇、过滤层及控制器,防护服上至少设有三个进出气孔,风扇至少设有两个、分别安装在进出气孔上;过滤层设置于进出气孔处和/或风扇外侧;控制器与风扇电性连接,用于控制风扇的正转和反转。通过风扇正转向防护服内注入空气,通过空气在防护服内和人体之间流动、并带走人体散发出的热量,达到降低防护服内的温度、减少穿戴人员出汗量、增加了穿戴人员的舒适感之目的,保障了医护人员的健康;通过风扇反转能够将防护服内的空气排出,同时吹掉过滤层外侧拦截的灰尘、微小颗粒、细菌、病毒,保障过滤层的过滤效果和寿命。 【EN】The invention relates to an inflatable cooling back-flushing protective garment, which at least comprises a protective garment, fans, filter layers and a controller, wherein the protective garment is at least provided with three air inlet and outlet holes, and the fans are at least two and are respectively arranged on the air inlet and outlet holes; the filter layer is arranged at the air inlet and outlet hole and/or the outer side of the fan; the controller is electrically connected with the fan and used for controlling the forward rotation and the reverse rotation of the fan. Air is injected into the protective clothing by the forward rotation of the fan, flows between the protective clothing and a human body through the air, and takes away heat emitted by the human body, so that the aims of reducing the temperature in the protective clothing, reducing the sweat amount of a wearer and increasing the comfort of the wearer are fulfilled, and the health of medical care personnel is guaranteed; can be with the air escape in the protective clothing through the fan reversal, blow off dust, tiny particle, bacterium, the virus of the interception in the filter layer outside simultaneously, ensure the filter effect and the life-span of filter layer.

摘要:【中文】本发明涉及一种反吹过滤口罩及使用方法。该反吹过滤口罩至少包括:口罩主体、风扇、过滤件、排气阀、控制器,口罩主体上至少设有两个进出气孔和一个排气孔,风扇设置于所述进出气孔内,过滤件设置于所述风扇外侧,排气阀设置于所述排气孔内,控制器与所述风扇电性连接。本发明具备以下优点和积极效果中的至少之一:通过风扇正转向口罩主体内注入空气,降低佩戴人员的吸气阻力,保障佩戴人员的吸气质量和安全;通过风扇反转吹掉过滤件外侧拦截的灰尘、微小颗粒、细菌、病毒,提高了过滤件的过滤效果和寿命。另外,当两个风扇中的一个风扇发生停止运转时、另一个风扇进入恒速模式运行,也能实现反冲洗的目的,尤其在排气孔处采用螺帽封堵更佳。 【EN】The invention relates to a back-blowing filter mask and a using method thereof. This blowback filter mask includes at least: gauze mask main part, fan, filter piece, discharge valve, controller are equipped with two business turn over gas pockets and an exhaust hole in the gauze mask main part at least, the fan set up in the business turn over gas pocket, filter the piece set up in the fan outside, discharge valve set up in the exhaust hole, the controller with fan electric connection. The invention has at least one of the following advantages and positive effects: air is injected into the mask main body through the forward rotation of the fan, so that the air suction resistance of a wearer is reduced, and the air suction quality and safety of the wearer are guaranteed; the dust, tiny particles, bacteria and viruses intercepted outside the filtering piece are blown off through the reverse rotation of the fan, so that the filtering effect and the service life of the filtering piece are improved. In addition, when one fan of the two fans stops running, the other fan enters a constant speed mode to run, the purpose of backwashing can be achieved, and particularly, the exhaust hole is better sealed by a screw cap.
