The invention provides a non-contact elevator key auxiliary panel, which comprises a housing capable of being buckled on the surface of an elevator key panel; the part of the housing facing each key forms a transparent area; the front surface of the housing corresponding to the central position of each key is respectively provided with an air hole with a ventilation aperture of 1-3mm; an air pump is connected to the inner space of the housing; the periphery of the housing is in airtight contact with the surface of the elevator key panel; therefore, when the air pump inflates the inner space of the housing, air can only be sprayed out from each air hole; a cover cap is further provided with a photosensitive sensor coupled to a control module of the air pump; when shading is formed on the front face of the photosensitive sensor, the air pump continuously inflates air into the housing; and otherwise, the air pump stops rotating. According to the auxiliary panel, the keys can make action response under the condition that fingers of a person taking an elevator do not make contact with the keys; and therefore, the contact type infection phenomenon is avoided to the maximum extent.
本发明提供一种非接触式电梯按键辅助面板,包括可以扣装在电梯按键面板表面的罩壳,罩壳面对各按键的部分形成透明区,且罩壳的正面对应于各按键的中心位置,分别开设有一个通气口径为1mm~3mm的气孔;壳罩内部空间连接一个气泵,且壳罩的周边与电梯按键面板表面保持气密接触,以使气泵向壳罩内部空间充气时,气体只能从各气孔向外喷出;罩盖上还设有耦合于气泵的控制模块的光敏传感器,当光敏传感器的正面形成遮光时,气泵向壳罩内部连续充气,否则使气泵停转。该辅助面板可以使乘坐电梯的人员,在手指不接触按键的情况下,使按键做出动作响应,从而最大限度地避免接触式感染现象。
