The invention provides an elevator key epidemic prevention auxiliary panel which comprises a housing capable of being buckled on the surface of an elevator key panel, a key cover is arranged in the housing corresponding to each elevator key, and an air hole is formed in the center of the front face of the key cover; after the cover shell is buckled on the elevator key panel, a main cavity is formed between the cover shell and the elevator key panel, key cavities are formed between the key covers and the elevator keys, connection and disconnection of an air path are achieved between the key cavities and the main cavity through electromagnetic valves, and air in the main cavity can only enter the key cavities and then can enter the elevator keys. The air flows out from the air holes in the front of the key cover; the auxiliary panel further comprises an air pump, and when the air pressure of the air pump in the main cavity is lower than a set value, the air pump inflates the main cavity. A photosensitive sensor is further arranged in each key cover, when the photosensitive sensor is shaded, the corresponding electromagnetic valve is opened, and otherwise, the electromagnetic valve is kept closed. According to the auxiliary panel, the key can make action response under the condition that fingers of a passenger do not contact the key completely.

    本发明提供一种电梯按键防疫辅助面板,包括可以扣装在电梯按键面板表面的罩壳,其内部对应于各电梯按键,再分别制有一个按键罩,且其正面中心制有气孔;罩壳扣装于电梯按键面板后,罩壳与电梯按键面板之间形成主腔体,而各按键罩与电梯按键之间形成各个按键腔体,各按键腔体与主腔体之间分别通过电磁阀实现气路的通断,主腔体内的空气只能进入按键腔体后,再从按键罩正面的气孔流出;所述辅助面板还包括气泵,该气泵在主腔体内的气压低于设定值时,向主腔体内充气;各按键罩内还设有光敏传感器,其被遮光时,开启其所对应的电磁阀,否则使该电磁阀保持关闭。该辅助面板可以使乘客在手指完全不接触按键的情况下,使按键做出动作响应。
