Abstract
The utility model relates to a miniature inertia wheel compressor, which structurally includes a motor, a casing, an inertia wheel, a piston set, and a seal material. A power output shaft of the motor is fixedly connected with the inertia wheel; one end of a piston rod is movably connected with the inertia wheel, and the other end of the piston rod is connected with a piston; a piston is arranged in a cylinder and sleeved with a seal ring; a retainer ring is used for compressing the seal ring and the piston tightly; a cylinder cover is fixed at one end of the cylinder; an air inlet valve plate and an air outlet valve plate are fixed on two sides of the cylinder cover respectively; an air inlet is arranged on a compressor casing; and an air outlet is arranged on a compressor end cover. The miniature inertia wheel compressor adopts the large-torsion outer rotor motor which runs stably as the power source, and drives the piston to do reciprocating linear movement along the inner wall of the cylinder, and the inertia wheel increases the thrust torsion as driven by the piston and meanwhile plays the function of adjusting the transmission balance during the movement process, so that the vibration and the noise during the work process can be reduced. Under the conditions of same air pressure and flow quantity, the compressor has greatly reduced volume and weight, runs stably and is low in noise.
Description
Technical field
The utility model relates to compressor, especially a kind of micro-compressor.
Background technique
Along with the development of sieve technology, oxygenerator miniaturization, portability more and more receive publicity.And the power source of small-sized oxygenerator is usually from micro-compressor.This type of micro-compressor satisfies except that needs the performance parameters such as flow, has also proposed such as size index requests such as little, in light weight, power consumptive province, low noise.
The model utility content
The utility model purpose is to provide a kind of structural design scheme that can be used for the oxygenerator micro-compressor.
For achieving the above object, the technical solution of the utility model is, this micro-compressor formation includes motor, flying wheel, piston rod, piston, seal ring, back-up ring, cylinder, cylinder head, check valve sheet, compressor housing, compressor head, the compressor top cover, the structural feature of this miniature compression is: the motor power output shaft is with flying wheel fixedlys connected, piston rod one end and flying wheel are movably connected, the piston rod the other end is connected with piston, piston is positioned at cylinder, piston sleeve is equipped with seal ring, and seal ring and piston are compressed with back-up ring, cylinder head is fixed in cylinder one end, air-intake valve plate and exhaust valve plate are individually fixed in the cylinder head both sides, suction port is arranged at compressor housing, and relief opening is arranged at compressor head.
In technique scheme, the suction port on the described compressor housing becomes space 90 degree to be provided with the relief opening that compressor end covers, with gas collecting and the discharge that makes things convenient for installing space and different direction.
In technique scheme, described motor is the external rotor brushless adjustable frequency motor.
The utility model advantage: adopted operate steadily, external rotor electric machine that moment of torsion is big is as power source, driven plunger does reciprocating linear motion along cylinder inner wall, flying wheel increases the thrust moment of torsion when piston actuated, also play simultaneously the regulating action of the transmission balance of movement process, to reduce the working procedure vibration, reduce noise.By the external rotor electric machine and the selection of being used to take turns, this structure is adjusted a little after, the inlet and outlet mouth is inverted just to can be and is vacuumized.This machine reaches under the situation of equal air pressure, flow, and volume and weight significantly reduces, and, operating steadily, noise is low.

Embodiment one:
Accompanying drawing 1 is a present embodiment structure sectional view.
Motor 12 adopts the external rotor brushless variable-frequency motor, the rotatingshaft 13 of this motor is fixing with flying wheel 2, piston and piston rod 3 as a whole parts, one end of piston rod 3 then is connected in flying wheel 2, seal ring 6 is set in piston, and be fixed by back-up ring 7, cylinder head 8 is fixed in cylinder 5 left end, check valve sheet (I) 9 is fixed in cylinder head 8 right flanks, check valve sheet (II) 10 then is fixed in cylinder head 8 left surfaces, be provided with seal ring between cylinder head 8 and the cylinder 5,11 of compressor heads are fixed in cylinder head 8 left sides, are provided with air chamber and relief opening in compressor head 11, suction port becomes space 90 degree to be provided with relief opening, can make things convenient for the gas collecting and the discharge of installing space and different direction, compressor top cover 4 is positioned at the top of compressor housing 1, is provided with seal ring between compressor top cover 4 and the compressor housing 1.
Flying wheel in the present embodiment is transformed into the rotation of motor rotation axis 13 to-and-fro motion of piston rod on the one hand, and flying wheel has also played on the other hand and reduced vibration, reduces the effect of mechanical noise.
Present embodiment is pressed into the pressurized gas of cylinder 5 air chamber of end cap 11 by the direct transmission flying wheel 2 of motor rotation axis, piston rod 3; Valve block when calming the anger (I) 9 is closed, and valve block (II) 10 is opened.Valve block during backhaul (I) 9 is opened, and valve block (II) 10 is closed, and fills to guarantee cylinder air chamber gas.
The present embodiment volume is little, and is in light weight, vibrates for a short time, and noise is low, is applicable to the occasions such as portable oxygenerator of medical treatment, family expenses.
Embodiment two:
In the present embodiment, compresser cylinder and compressor housing adopt whole the manufacturing, to improve the tightness of complete machine.
Embodiment three:
In the present embodiment, adopt two cylinders, two cylinder-bore axises linearly, i.e. 180 degree.This need both be connected with the piston rod in left side at the flying wheel that is fixed on the motor rotation axis, be connected with the piston rod on right side again, the left hand cylinder exhaust, the right cylinder air inlet, this structure can further reduce mechanical vibration, reduces noise, certainly, the motor that present embodiment adopts requires moment of torsion bigger, and efficient is higher.
