Technical field
The present invention relates generally to portable air compressor, relates more specifically to have the Portable air compressor of improved portability and robustness.
Background technique
Little air compressor has become the common tool in family, workshop, building site.For family, can the light compressor of operating weight, be used for amusement and other small-power purposes, fill a small amount of gas such as charge movement or amusement equipment or when the urgency to automobile tire.This task needs the pressurized air and/or the low relatively airspeed of relatively low pressure.By using the compressor by small and light motor-driven little, low capacity and/or low pressure, it is very light that the weight in these structures keeps, and portability is maximized.In addition, by omitting high-pressure bottle (compressed air bottle just) and lubricating oil system, on weight, size and cost, obtained significant saving.
Yet, a lot of higher air pressures of need of work, and/or bigger instantaneous air-flow needs, this instantaneous air-flow surpasses the ability of the compressor that hobby or amusement use typically.In order to satisfy, must increase the size of compressor and associated motor or motor to than highpressure with than the needs of high gas flow task.And, not that the size of design compressor satisfies the maximized requirement of theoretic instantaneous air-flow, common actual design is the air reservoir that comprises a compression of compressed air bottle or other pressurized container form.Usually the jar that has an output controller can hold a certain amount of pressurized air, to satisfy the maximum value of supply load, allows simultaneously to use the less and lighter compressor of inflating as jar, and can satisfy the average compressed air require of special purpose.
In fact the compressed air cylinder of pressure and the flow level of need meeting the expectation and bigger compressor have increased the weight and the overall dimension of compressor apparatus.The element that designs for high pressure and high power capacity task can reach weight and the size that known motor vehicle are installed rapidly, and perhaps the breakdown trailer structure is unique actual form.And, the air compressor of Medium Capacity scope be the job site common equipment and also can be portable by the people.
Can comprise one or the fixing or supporting mechanism of a motor or motor is installed in it thereon by the portable compressed air unit of people at present, an air compressor, a compressed air bottle is discharged manifold and multiple valve, instrument and controller for one.A lot of bigger portable structures have wheel, often are called hand-push structure, make them to be moved by an independent people.There is the example of the air compressor of wheel to comprise the D55170 type and the D55270 type of DeWalt board.
And, the user of the compressor of the professional grade of some Medium Capacities find must or expectation have an energy with portable and the compressor that carries.The usual method that the air compressor manufacturer takes is that the redesign air compressor is to reduce its weight.Although this effort is arranged, the frequent weight of professional grade compressor of Medium Capacity surpasses 50 pounds, and still is difficult to portable and mobile, even those strong men.
Except weight issue, know that also the professional grade compressor transportation of Portable Medium Capacity bothers very much.In this, use the structure of two cylindrical tanks or flat jar independent (that is to say that diameter has the cylindrical tank of male end greatly and highly for a short time) to become generally, have installation and design for compressor and motor are installed simultaneously.Give an example the side that the structure of using two cylindrical tanks typically is installed in compressor and motor jar, and an end of using independent one flat jar structure typically compressor and motor to be installed in jar.
These traditional air compressors are arranged and are made equipment have a big relatively bottom or base, and are positioned at the center of gravity of base near center position.This layout makes air compressor have in a metastable structure of its operation period simultaneously, is being with these structures to mention and is carrying air compressor to become very clumsy and difficult.In this, these structures have typically been used a handle (being used to mention and carry air compressor), handle is connected on the suitable structure, and such as bearing or compressed air bottle, its position is vertically set on the center of gravity top of whole compressed air unit.The direction of handle is provided with to such an extent that need compressed air unit to be mentioned vertically upward usually, and is carried on identical with its direction of operating substantially direction.
Yet, mentioning with carrying known medium compressed air unit by this way is relative difficulty, because the base of these compressed air units is relatively large easily and therefore need the user to control compressed air unit to overhanging arm a little, user's wrist just is in bent state like this.The center of gravity of compressed air unit more in the close effort of user's central axis, the user will typically tilt its upper limbs away from the load of compressed air unit, and therefore make body gesture uncomfortable and mention unhandily and the transport air compression device.
