Embodiment Construction
[0031]The invention is a micro-miniature integral structure cold air propeller, which is composed of a micro-miniature pressure reducer with a plane structure, a rolling ball valve core shut-off valve and a micro-miniature plane nozzle. According to the size and thrust of the designed cold air propeller, different processing and assembly techniques are required, and the corresponding structural details and characteristics are also different. figure 1 Shown is a 40mm small integrated structure cold air propeller made by precision machining technology; Figure 2 shows a 5mm miniature integrated structure cold air propeller made by planar micro technology, of which Figure 2(a) and Figure 2(b) , Figure 2(c) is a schematic diagram of its layered structure, and Figure 2(d) is its assembly diagram.
[0032] figure 1 Shown is a 40mm small integrated structure cold air thruster, the pressure reducer and the shut-off valve share the bottom plate 1, the middle plate 3, the top plate 6 an...
