Air compressor, air storage, and high pressure cleaning machine structure
US 20030129065 A1
Abstract
An air compressor, air storage, and high pressure cleaning machine structure comprised of an air compression and air storage mechanism and a high pressure cleaning mechanism that are powered by a single electric motor in an integrated arrangement, wherein the two protruding ends of a main shaft in the electric motor are inserted into a unidirectional bearing, following which they are respectively coupled to the air compression, air storage mechanism and the high pressure cleaning mechanism. The two mechanisms are installed on a foldable two-section wheeled frame and the user controls the electric motor with a toggle switch to selectively deviate the main shaft in the electric motor towards one of the two unidirectional bearings such that said electric motor drives either the air compression and air storage mechanism or the high pressure cleaning mechanism. As such, the two-in-one arrangement effectively reduces space occupancy and facilitates operating convenience.

Description
    BACKGROUND OF THE INVENTION
  • [0001]
    1. Field of the Invention
  • [0002]
    The invention herein relates to air compressor, air storage, and high pressure cleaning machine structure that provides for the powering of an air compression and air storage mechanism and a high pressure cleaning mechanism by a single electric motor in an integrated arrangement, wherein the two ends of a main shaft in the electric motor are each inserted into a unidirectional bearing such that operating the electric motor toggle switch selectively deviates the main shat towards one of the two unidirectional bearings to drive either the air compression and air storage mechanism or the high pressure cleaning mechanism, thereby effectively reducing space occupancy and facilitating operating convenience.
  • [0003]
    2. Description of the Prior Art
  • [0004]
    Conventional air compressor and high pressure cleaning machine structures typically consist of two separate units, wherein the said air compressor and the high pressure cleaning machine are independently operated and utilized. Users possessing both types of equipment have discovered that since they are each powered by an electric motor, if the air compressor and the high pressure cleaning machine were integrated, the physical dimensions can be reduced by half, which would not only save set up space, but also facilitate utilization and increase practical value.
  • [0005]
    In view of the said situation, the inventor of the invention herein submitted the content of the present invention to further refine and promote utilization conventience.
  • SUMMARY OF THE INVENTION
  • [0006]
    The primary objective of the invention is to provide an air compressor, air storage, and high pressure cleaning machine structure in which the two ends of a main shaft in the electric motor are each inserted into a unidirectional bearing, following which they are respectively coupled to the air compression and air storage mechanism and the high pressure cleaning mechanism and then installed on a two-section wheeled frame such that operating the electric motor toggle switch selectively deviates the main shaft towards one of the two unidirectional bearings to drive either the air compression and air storage mechanism or the high pressure cleaning mechanism, the resulting two-in-one arrangement thereby effectively reducing space occupancy and facilitating operating convenience.

  • DETAILED DESCRIPTION OF THE INVENTION
  • [0015]
    Referring to FIG. 1-A, FIG. 1-B and FIG. 1-C, the air compressor, air storage, and high pressure cleaning machine structure of the invention herein is comprised of an air compression and air storage mechanism 2 and a high pressure cleaning mechanism 3 installed on a wheeled frame 1 and an electric motor 4 that is utilized in an integrated arrangement by both of the said two mechanisms; the said wheeled frame 1 is a two-section type having an L-shaped upper union mount 11 and a lower union mount 12 situated at both sides of its approximate center point, with a plain hole 111 in the upper union mount 11 and a threaded hole 121 in the lower union mount 12 such that after a T-head bolt 13 is inserted and fastened, the wheeled frame 1 is rigidly extended (as shown in FIG. 2-A) and capable of being pushed to move the two mechanisms; conversely, when the T-head bolt 13 is loosened, the upper extent of the wheeled frame 1 can be folded down, as indicated in FIG. 2-B, to facilitate storage and conserve space; as for the electric motor 4 utilized in common by both the air compression and air storage mechanism 2 and the high pressure cleaning mechanism 3, as indicated in FIG. 1-C, the two protruding ends of a main shaft 41 in the electric motor 4 are each inserted into a unidirectional bearing 42, following which they are respectively coupled to the air compression and air storage mechanism 2 and the high pressure cleaning mechanism 3, and the air compression and air storage mechanism 2 is connected to an air tank 2A; and an air intake opening 21, two air output nipples 21, a high pressure water output nipple 31, a toggle switch 4A, and a pressure gauge are exposed on the exterior surface.
  • [0016]
    To operate the air compression and air storage mechanism 2, after the toggle switch 4A is moved from the center OFF position to the air compression position, electricity is supplied to start the rotation of the said electric motor 4, at which time the main shaft 41 in the electric motor 4 deviates towards the unidirectional bearing 42 of the air compression and air storage mechanism 2 which is then rotated in the same direction as the main shaft 41 and begins to function, with the main shaft 41 spinning freely in the other unidirectional bearing 42 because its rotational orientation is different and, as such, only the air compression and air storage mechanism 2 operate and the high pressure cleaning mechanism 3 remains in a disabled static state, as indicated in FIG. 3-A; conversely, to operate the high pressure cleaning mechanism 3, the toggle switch 4A is shifted to the high pressure cleaning position, electricity is supplied to start the rotation of the said electric motor 4, at which time the main shaft 41 in the electric motor 4 deviates towards the unidirectional bearing 42 of the high pressure cleaning mechanism 3 which is then rotated in the same direction as the main shaft 41 and begins to function, with the main shaft 41 spinning freely in the other unidirectional bearing 42 because its rotational orientation is different and, as such, only the high pressure cleaning mechanism 3 operates and the air compression and air storage mechanism 2 remains in a disabled static state, as indicated in FIG. 3-B; as such, user control of the electric motor 4 with the toggle switch 4A provides for the selective utilization of either the air compression and air storage mechanism 2 or the high pressure cleaning mechanism 3, the two-in-one arrangement effectively reducing space occupancy and facilitating operating convenience.
  • [0017]
    In summation of the foregoing section, since the invention herein is capable of providing progressive performance and meets new patent application requirements, the present invention is submitted to the patent bureau for review and the granting of the commensurate patent rights.
