Description

Technical Field

[0001] This utility model relates to the field of air compressor technology, and in particular to a small-sized air compressor. Background Technology

[0002] An air compressor is a mechanical device that compresses and stores gas. The air receiver is a crucial component of an air compressor, used to store compressed air and balance the compressor's air supply. Currently, most common air compressor air receivers adopt a cylindrical structure. Their manufacturing process typically includes the following steps: first, rolling a metal sheet into a cylindrical shape; then, welding end caps to both ends of the cylinder to form a sealed air storage space.

[0003] The traditional gas storage tank structure has the following technical problems: First, the traditional gas storage tank requires at least three main components (a cylinder and two end caps), which increases the production and assembly process. Second, the cylindrical cylinder requires specialized rolling equipment for rolling, which places high demands on equipment and processes. Furthermore, the traditional cylindrical gas storage tank requires a large horizontal space for installation, which is not conducive to miniaturization design and use in scenarios where space is limited, especially height. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a compact air compressor that is manufactured by welding two identical disc-shaped stamped parts together, thereby simplifying the manufacturing process, reducing production costs, and minimizing equipment size.

[0005] To achieve the above objectives, the present invention designs a small-volume air compressor, which includes an air storage tank for storing compressed air. The air storage tank includes two disc-shaped stamped parts that are positioned vertically opposite each other. The edges of the disc-shaped stamped parts are welded together. The length of the radial section of the air storage tank in the horizontal direction is greater than the length of the radial section in the vertical direction.

[0006] Furthermore, the radial cross-section of the gas storage tank is elliptical.

[0007] Furthermore, the plane containing the annular weld formed by welding the two disc-shaped stamping parts is parallel to the horizontal plane.

[0008] Furthermore, the two disc-shaped stamped parts have the same structure.

[0009] Furthermore, the gas storage tank is provided with several reinforcing ribs that connect the inner walls of the two disc-shaped stamped parts.

[0010] Furthermore, both disc-shaped stamped parts are stamped from metal sheets of the same specification.

[0011] Furthermore, it also includes a travel wheel, a compressor body, and two handles; the bottom of the gas tank is provided with a wheel frame, and the travel wheel is rotatably connected to the wheel frame; the top of the gas tank is provided with a compressor base, and the compressor body is fixed to the compressor base by bolts passing through the shock-absorbing pads.

[0012] Furthermore, the two handles are symmetrically arranged on both sides along the horizontal length of the gas storage tank.

[0013] Furthermore, the outer surface of the gas storage tank is coated with a protective coating that covers the circumferential weld of the two disc-shaped stamping parts.

[0014] This invention relates to a compact air compressor that utilizes a structure where two disc-shaped stamped parts are placed vertically and welded together to form an integrated air tank. This design results in a flat radial cross-section, or overall shape, of the air tank. This simplifies the tank's component structure, reduces welding processes, and lowers manufacturing costs. Furthermore, because the two disc-shaped stamped parts have identical structures, they can be manufactured using the same stamping tools, improving component versatility and facilitating mass production. In addition, the flat air tank structure reduces the tank's height and the overall size of the air compressor. Combined with features such as wheels and handles on the air tank, this design facilitates movement and improves space utilization, making it particularly suitable for applications requiring frequent relocation and with limited installation space.

[0018] The components include: gas tank 10, wheel frame 11, compressor base 12, shock absorber 13, disc-shaped stamped part 20, disc edge 21, travel wheel 30, compressor body 40, and handle 50. Detailed Implementation

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] like Figures 1 to 3As shown, the small-volume air compressor described in this embodiment includes an air tank 10 for storing compressed air. Specifically, the air tank 10 includes two vertically opposed disc-shaped stamped parts 20, with the disc edges 21 of the two disc-shaped stamped parts 20 welded together. This structural design simplifies the three-piece air tank 10 (cylinder body plus two end caps) in related technologies to a two-piece structure, simplifying the manufacturing process, reducing the number of parts, and significantly reducing production costs. In this embodiment, the two disc-shaped stamped parts 20 are preferably stamped from metal sheets of the same specification. This makes the two disc-shaped stamped parts 20 have the same structure, allowing them to be stamped using the same set of molds, improving the versatility of the parts and facilitating mass production.

[0021] Furthermore, the horizontal length L1 of the radial cross-section of the air tank 10 is greater than the vertical length L2 of the same radial cross-section, making any radial cross-section of the air tank 10 flat, i.e., the air tank 10 has an overall flat structure. This flattened design effectively reduces the height of the air tank 10, thereby reducing the overall volume of the air compressor, making it more compact, portable, and easier to store. This design is particularly suitable for applications with strict volume requirements, such as vehicle-mounted use, or scenarios where pneumatic tools are operated in confined spaces. In one specific embodiment, as... Figure 2 As shown, the radial cross-section of the gas storage tank 10 is elliptical, which further optimizes space utilization while ensuring strength.

[0022] In some embodiments, such as Figure 3 As shown, the plane of the annular weld formed by the welding of the two disc-shaped stamping parts 20 is parallel to the horizontal plane. Thus, during positioning welding, since the weld lines are on the same horizontal plane, the lower disc-shaped stamping part 20 can be stably placed on the worktable, and the edges 21 of the upper disc-shaped stamping part 20 can be accurately aligned. The two disc-shaped stamping parts 20 can then be fixed in place using ordinary flat clamps for welding, preventing tilting and misalignment and ensuring weld precision.

[0023] In some embodiments, the gas storage tank 10 is provided with a plurality of reinforcing ribs (not shown) connecting the inner walls of the two disc-shaped stamped parts 20. In this embodiment, the reinforcing ribs are used to enhance the structural strength of the gas storage tank 10 and ensure its good safety when subjected to pressure.

[0024] In some embodiments, such as Figure 1 , Figure 2As shown, it also includes a travel wheel 30, a compressor body 40 and two handles 50; the bottom of the gas storage tank 10 is provided with a wheel frame 11, and the travel wheel 30 is rotatably connected to the wheel frame 11; the top of the gas storage tank 10 is provided with a compressor base 12, and the compressor body 40 is fixed to the compressor base 12 by bolts passing through the shock-absorbing pad 13.

[0025] Specifically, the wheel frame 11 includes two parallel supports. Each support has an axle mounting hole at its end away from the gas tank 10. Two travel wheels 30 are rotatably mounted in the axle mounting holes via axles, facilitating equipment movement. The compressor base 12 has multiple mounting holes. The compressor body 40 is bolted through shock-absorbing pads 13 and connected to the mounting holes to fix the compressor body 40 onto the compressor base 12. The shock-absorbing pads 13 are used to reduce vibrations generated during compressor operation. In this embodiment, two handles 50 are symmetrically arranged on both sides along the horizontal length of the gas tank 10 to facilitate operator handling of the equipment.

[0026] In some embodiments, the outer surface of the gas storage tank 10 is coated with a protective coating that covers the circumferential weld of the two disc-shaped stampings 20. The protective coating completely covers the circumferential weld to prevent rusting on the surface of the gas storage tank 10 or at the weld, thereby extending its service life.

[0027] The compact air compressor provided in this embodiment employs a storage tank structure consisting of two disc-shaped stamped parts placed vertically opposite each other and welded together. This results in a flat radial cross-section, or overall shape, of the storage tank. This not only simplifies the component structure of the storage tank but also reduces welding processes, lowering manufacturing costs. Furthermore, since the two disc-shaped stamped parts have identical structures, they can be manufactured using the same stamping tools, improving parts versatility and facilitating mass production. In addition, the flat storage tank structure reduces the height of the storage tank, decreasing the overall volume of the air compressor. Combined with the wheels and handles on the storage tank, this facilitates the movement and handling of the equipment and improves space utilization, making it particularly suitable for applications requiring frequent relocation and with limited installation space.
