Abstract

The invention discloses a compact type environment-protection oil-free air compressor comprising a head stock, wherein a motor is arranged in the head stock; wind impellers having the consistent wind blade direction are respectively arranged on the front and the back ends of a revolving shaft of the motor; a belt wheel is flexibly arranged on the head stock; the belt wheel is connected with a pinion arranged on a front revolving shaft of the motor through a belt; the belt wheel is eccentrically connected with a piston connecting rod through a bearing; a piston ring is arranged on the top end of the piston connecting rod; and the motor drives the piston ring to make a back and forth movement in a cylinder to achieve the purpose of compressing air. In the invention, an oil lubrication system on the cylinder of the common air compressor is removed, therefore, not only the problem of environment pollution caused by compressed air containing oil and waste lubrication oil is solved, but also the structure of the whole compressor is simplified, maintenance cost is greatly reduced, and the miniaturization and the portability of the air compressor are realized.

Description

A kind of compact type environmental protection oil-free air compressor

Technical field

The present invention relates to a kind of air compressor, particularly a kind of compact type environmental protection oil-free air compressor.

Background technique

Air compressor has been widely used in the every field in our life, and is bringing into play important role.Need to use lubricant oil to give piston lubrication in the common air compressor work, this not only causes the air compressor structure complicated, and, the more important thing is that discarded lubricant oil can cause environmental pollution because in daily use, need periodic replacement or add lubricant oil and make maintenance cost rise.In addition, owing to adopt oil lubrication, produce lubricated oil droplet or its steam in the compressor operating inevitably and sneak into problem in the pressurized air, this has just limited the application area of common oil laden air compressor, and for example medical field just needs not have the pressurized air of oil.In addition, in some cases, when for example needing to carry air compressor and carrying out outdoor study, traditional oil laden air compressor means too complexity is unfavorable for carrying, and for the domestic consumer, its maintenance is too loaded down with trivial details, is unfavorable for popularizing.

Summary of the invention

In order to satisfy users' demand, the invention provides a kind of simple and compact for structurely, portable, the no oil ring that is easy to safeguard is protected air compressor.

The technical solution used in the present invention can be described as:

A kind of compact type environmental protection oil-free air compressor, comprise headstock, motor is installed in the headstock, be separately installed with fan blade on the front end and back end of machine shaft, be movably installed with belt wheel on the described headstock, belt wheel is connected with small gear on being installed in the motor front rotary shaft by synchronizing jugged belt, be connected with piston rod by bearing off-centre on the belt wheel, the piston rod top is equipped with piston ring, and be positioned in the compressor cylinder block on headstock top, described cylinder block is pressed together on the headstock top by cylinder head and air valve board component.During compressor operating, motor drives piston ring to-and-fro motion in cylinder by small gear, belt, belt wheel and piston rod, and by the control of air valve board component, up giving vent to anger, descending air inlet realizes compressed-air actuated function.

As further improvement in the technical proposal, the described fan blade direction unanimity that is contained in two fan blades of motor rotation axis front end and back end, two fan blade synchronous workings form the integral heat sink that compressor is strengthened in the air channel.

The invention has the beneficial effects as follows:

The oil-free air compressor that the present invention proposes has adopted the piston ring that uses self lubricating material to make to replace traditional metallic piston, need not lubricant oil in the working procedure and participate in the lubricated of piston region, this has not only solved pressurized air oil-containing and waste lubrication oil problem of environment pollution caused, and owing to cancelled the oil lubrication system of cylinder, the structure of whole compressor is simplified, maintenance cost also thereby significantly reduces, and the miniaturization and the portability of air compressor also are achieved.In addition, the oil-free air compressor that the present invention proposes adopts synchronous toothed belt transmission, the skidding when having avoided the ordinary straps transmission, and adopted the design of double fan forced heat radiation, increased the load carrying capacity and the operating life of compressor.

Embodiment

As shown in the figure, a kind of compact type environmental protection oil-free air compressor that the present invention proposes, comprise headstock 1, motor 2 is installed in the headstock 1, be separately installed with fan blade 21,22 on the front end and back end of described motor 2 rotating shafts, also be movably installed with belt wheel 3 on the headstock 1, belt wheel 3 is connected with small gear 5 on being installed in the motor front rotary shaft by belt 4, be connected with piston rod 6 by bearing off-centre on the described belt wheel 3, described piston rod 6 tops are equipped with the piston ring 61 by 62 pressings of piston pressing plate, and are positioned in the compressor cylinder component element 7 on headstock 1 top.Compressor cylinder component element 7 comprises cylinder head 72, cylinder head gasket 74, air valve board component 73, O-ring seals 75 and cylinder block 71 from top to bottom, and is pressed together on headstock 1 top by the screw sealing.In addition, described air valve board component 73 comprises the air valve plate 731 that has pore, the upper/lower terminal of described air valve plate 731 is installed with respectively and the corresponding air-intake valve plate 732 of pore and the valve block 733 of giving vent to anger, and air-intake valve plate 732 lower ends also are fixed with the capable compressing tablet 734 of fan that is used to control air-intake valve plate 732 open angles.During compressor operating, motor drives piston ring to-and-fro motion in cylinder that self lubricating material is made by small gear, belt, belt wheel and piston rod, and by the control of air valve plate, up giving vent to anger, descending air inlet realizes compressed-air actuated function.Like this, oil-free air compressor of the present invention no longer needs the oil lubrication system of cylinder, this has not only solved pressurized air oil-containing and waste lubrication oil problem of environment pollution caused, and owing to cancelled the oil lubrication system of cylinder, the structure of whole compressor is simplified, maintenance cost also thereby significantly reduces, and the miniaturization and the portability of air compressor also are achieved.

In addition, the fan blade direction unanimity of described fan blade 21,22, two fan blades of driven by motor rotate synchronously and form the heat radiation that compressor has been strengthened in the air channel during compressor operating.

In addition, described belt 4 is synchronous toothed belt, and this belt can be avoided the skidding of belt effectively.
