An optical switch ( ) includes a shell ( ) forming an input port ( ) and first and second output ports ( ) with an optical switching subassembly enclosed therein between the input port and the output ports. The optical switch subassembly includes two light transmitting blocks ( ) having surfaces spaced from and opposing each other. Two light transmitting liquid sections having a refractive index substantially identical to that of the blocks are movably retained between the surfaces. The liquid sections are spaced from each other forming an air section therebetween. A piezoelectric element ( ) is in physical engagement with the liquid sections. The piezoelectric element can be electrically biased to move the air section and the liquid sections between a first position wherein the air section is located on an optical path from the input port to the second output port, light from the input port being fully reflected by the surfaces of the blocks and being redirected to the first output port and a second position where one of the liquid sections is located on the optical path, allowing light to completely travel along the optical path and thus switching the light from the input port to different output ports.

Optical switch with liquid-air-liquid switch assembly

An optical switch includes a casing in which a fixed first crystal element having a first surface and a moveable second crystal element sharing the same refracting index with the first crystal element and having a second surface corresponding to the first surface of the first crystal element are arranged. A driving device selectively drives the second crystal element to move relative to the first crystal element between a first position and a second position. In the first position, the second surface of the second crystal element abuts against the first surface of the first crystal element, to allow a light beam transmitting into the first crystal element to pass through the second crystal element without substantial reflection. In the second position, the first and second surfaces are separated from each other, forming a gap therebetween whereby a light beam transmitting into the first crystal element is fully reflected on the first surface and leaves the optical switch in different direction thereby achieving switching operation.

An air blowing tool includes a connecting pipe ( ) and an air blowing head ( ). The air blowing head includes an inner wall ( ) and an outer wall ( ). An annular passage ( ) is defined between the inner and outer walls. The inner wall encloses and defines a heating space ( ) for accommodating a package ( ) to be heated. An annular outlet ( ) is defined in the inner wall. The annular outlet communicates with the annular passage and with the heating space.
