Abstract

The utility model relates to a two-purpose air compressor for a motor vehicle tyre to fill and exhaust the air. The utility model is additionally provided with an air inlet pipe (3) connected with an air intake of an air filtering device (4) on the basis of the structure of the present air compressor. The other end of the air inlet pipe (3) is connected with a rubber air suction pipe (6). The utility model has the functions of air fill and air exhaust. After the air is exhausted, the demounting work of the inner tyre is easy and is helpful for preventing the inner tyre from being damaged, and the air of the inner tyre, which is drawn away can also be used as the air source for pressurizing the inner tyre again; thus, the labor intensity and the labor efficiency of workers are improved, and the power consumption is not increased simultaneously.

Description

Two purpose air compressor

The utility model relates to the automobile tyre inflator, particularly a kind of double functional air compressor.

The air compressor of giving Motor Vehicle (as automobile, tractor) tyre inflation that uses at present, mainly by noise elimination air-strainer (abbreviation air-strainer), inflating pump, motor, gas receiver, barometer, safety valve, add air cock and the high pressure gas-adding pipe is formed.Air enters inflating pump by air-strainer, enters gas receiver after the pressurization again and removes moisture content.Barometer gives to show pressure.When air pressure surpassed regulation, safety valve was opened automatic vent.

When tire changed in repairing, because atmospheric cause, the residual all the time a part of gas of interior tyre cavity caused play the inner tube of a tyre to feel that difficulty is particularly difficult when particularly the inner tube of a tyre and cover tire have adhesion phenomenon.When the workman operates, usually be that both hands and a pin are used entirely, not only time-consuming but also require great effort.Simultaneously, the inner tube of a tyre shortens its working life because of being subjected to excessively pullling.These problems are insurmountable by existing the air compressor with aerification function.

The purpose of this utility model provides a kind of double functional air compressor, it not only has the aerification function of existing air compressor, and have the function of exhaust, thereby can alleviate the labor intensity of workman when pulling down the inner tube of a tyre and the working life that helps prolonging the inner tube of a tyre greatly.

The purpose of this utility model is achieved in that on the architecture basics of existing air compressor, sets up a suction tude, and this suction tude links to each other with the inlet hole of air-strainer, and the other end of suction tude links to each other with the rubber sucking pipe.

Above-mentioned suction tude is two logical structures, also can make following three-port structure: a logical atmosphere, a plunger is housed on this mouth of pipe, and two annexation is with aforesaid two logical suction tude in addition.The effect of plunger is, blocks the mouth of pipe with it, and the rubber tube of another connection has just become sucking pipe.

Above-mentioned rubber sucking pipe is inserted into waits to repair on the valve cock of the inner tube of a tyre, start compressor after, then the very fast quilt of the residual gas in the inner tube of a tyre is taken away and is sent in the gas receiver and cave in.Like this, the good effect that is produced is: the one, overcome defective of the prior art, and cause down the work of the inner tube of a tyre to become easily and be beneficial to the protection inner tube of a tyre to be without prejudice; The 2nd, residual gas can be used as the source of the gas that tire pressurizes again again, has realized the conversion of energy, that is to say when improving labor strength, raising the efficiency, and consumption does not increase electric power; The 3rd, when having finished the function of exhaust, pull up plunger (during two logical suction tude, then pull up the rubber sucking pipe) from suction tude, the high pressure gas-adding pipe is inserted on the valve cock, start compressor, then tire can pressurizedly have been inflated again, in brief, the utlity model has two kinds of functions of exhaust and inflation, to adapt to different needs.

Accompanying drawing is a structural representation of the present utility model.

The utility model is described in further detail below in conjunction with drawings and Examples.

The utility model removes and comprises air-strainer 4, and inflating pump, motor, gas receiver, barometer, safety valve, add outside air cock, the high pressure gas-adding pipe part (accompanying drawing is not drawn), also set up a suction tude 3, that is to say that the utility model has kept prior art constructions basically.Like this, both be convenient to make, and also be convenient to the air compressor of present use is transformed.

As shown in the figure, suction tude 3 can be two logical (drawing) or three-port structures: a logical atmosphere, this end are equipped with when plunger 1(two leads to structure can save these parts); One links to each other with rubber sucking pipe 6, and another then links to each other with the inlet hole screw thread of air-strainer 4 or weld and connects or directly insert.Sequence number 5 is inflating pump suction tude.With a chain rope plunger 1 is linked to each other with anti-lost with suction tude 3.Plunger 1 is provided with a screw thread plush copper that rubber case 2 is close to it.Rubber case 2 contacts with suction tude 3 inwalls.

Claims

1, a kind of double functional air compressor, comprise air-strainer (4) and inflating pump, motor, gas receiver, barometer, safety valve, add air cock and high-pressure air pipe part, the inlet hole that it is characterized in that air-strainer (4) links to each other with suction tude (3), and the other end of suction tude (3) links to each other with rubber sucking pipe (6).

2, compressor according to claim 1, it is characterized in that suction tude (3) is a three-port structure, the inlet hole with air-strainer (4) links to each other, and one links to each other with rubber sucking pipe (6), another logical atmosphere is equipped with a plunger (1) on the open to atmosphere mouth of pipe.

3, compressor according to claim 2 is characterized in that on the screw thread plush copper of plunger (1), is with a contacted rubber case of wall of the lumen (2) with suction tude (3).

4, compressor according to claim 1 and 2 is characterized in that suction tude (3) links to each other with the inlet hole screw thread of air-strainer (4) or welds to connect.
