Abstract: An automatic water discharge device is provided for use with a pneumatically operated apparatus and includes a housing including a water accumulation chamber; an electromagnetic valve coupled to the water accumulation chamber and including a bottom air discharge hole; and a detection mechanism arranged in the housing and in operative coupling with the electromagnetic valve. When the detection mechanism detects moisture entraining gas or air passing through the water accumulation chamber, the electromagnetic valve is activated to allow water to drain through the bottom air discharge hole. As such, operations of automatic detection, accurate draining, and effectively blocking impurities can be all performed and an advantage of maintaining the performance of the pneumatically operated apparatus may also be achieved.

Abstract: A clamping structure includes an object, a clamping component and an elastic component. The object has a hole and a containing space, wherein the containing space is connected to the hole. The clamping component includes a pillar, a bump and a head portion, wherein the bump and the head portion are connected to the pillar, and the pillar is adapted to be inserted into the hole and rotated such that the bump moves to the containing space. When the bump is located in the containing space, the elastic component is compressed between the object and the head portion, and the bump is positioned at the containing space by elastic force of the elastic component, such that the clamping component is fastened to the object.
