The invention discloses a knob switch. The knob switch comprises a knob switch main body and an air pressure check valve main body connected with the knob switch main body, the knob switch main body and the air pressure check valve main body are designed, an air nozzle on the air pressure check valve main body communicates with the air bags of a seat cushion and a backrest to supplement air for the air bags or release air from the air bags, and the purpose of improving the comfort of a human body is achieved; stroke blocks are arranged in a switch upper shell and a switch lower shell, so thatthe up-and-down movement of an ejector rod is controlled, the knob controls the states of the stroke blocks, and then whether the air bag leaks air or not is controlled; check valves are arranged in acheck valve upper shell and a check valve lower shell, so that the effect of automatically supplementing air to the air bag is achieved; therefore, the air bag can be actively inflated or deflated orpassively inflated in the absence of an air source, and the comfort of a human body is improved.
本申请公开了一种旋钮开关。包括旋钮开关主体和与所述旋钮开关主体连接的气压逆止阀主体;本申请通过设计旋钮开关主体与气压逆止阀主体,气压逆止阀主体上的气嘴与座垫及靠背的气袋连通,为气袋补气或者泄气,实现提高人体舒适性的目的;通过在开关上壳与开关下壳内设置行程块,使得顶杆的上下移动得到控制,旋钮控制行程块的状态,进而控制气袋是否泄气;通过在逆止阀上壳与逆止阀下壳内设置单向阀,实现为气袋自动补气的作用;因此本申请能够主动为气袋补气或泄气或者在无气源状态下被动为气袋补气,提高人体舒适性。
