Detailed description of the invention
The invention will be further described with preferred embodiment below in conjunction with the accompanying drawings.
Embodiment one
Provide the specific embodiment of a kind of microminiature compressor with rolling rotor, this pressure as Figure 1-3
Contracting machine includes: motor 101 and cylinder；Described cylinder includes: cylinder body 121, upper flange 105, cylinder
Lid 130, exhaust partition 111, the piston 107 being set in rotating shaft 103 and blade 125, blade
125 are fixed on cylinder body 121 by spring.
Shown in Fig. 3-5, described cylinder head 130 is provided with first row pore 133, second
Steam vent 138, air discharge duct and exhaust valve plate 135.Wherein, air discharge duct by first row air drain 131,
Second row air drain 134 and exhaust valve plate mounting groove 136 form, and described second row pore 138 is arranged
In one end of described exhaust valve plate mounting groove 136, described exhaust valve plate 135 is fixed by screws in institute
Stating the other end of exhaust valve plate mounting groove 136, described second row pore is closed by exhaust valve plate 135.
The degree of depth of described exhaust valve plate mounting groove 136 is more than described first row air drain 131 and second row air drain
134, so can keep its gas circulation；First row air drain 131, second row air drain 134 respectively with
The two ends of described valve block mounting groove 136 connect, and make first row pore 133 with second row pore 138 even
Logical；Described second row air drain 131 is the groove that one section of straight line is arranged, and described second row air drain 134 is with gas
The center of cylinder cap 130 is that circular arc is arranged.Cylinder head 130 is affixed to cylinder by installing hole 137
On body 121.
Wherein, at the second row pore 138 of cylinder head 130, being provided with flange 139 will be fixed on
Exhaust valve plate 135 jack-up in exhaust valve plate mounting groove 136, this flange 139 has the highest bright and clean
Degree, and it is provided with fillet, under the elasticity of exhaust valve plate 135, make exhaust valve plate 135 and second
Steam vent 138 is fitted the tightst, so can stop gas backflow, fully improve exhaust efficiency,
