Description

Technical Field

[0001] This application relates to the technical field of air compressors, and in particular to an air compressor with a bottom air intake structure. Background Technology

[0002] An air compressor is a device that draws in and compresses air, and then releases the compressed air into a storage tank. It is widely used in industries such as manufacturing, construction, and automotive repair.

[0003] In related technologies, the sheet metal housing of an air compressor has a cuboid structure, including a base plate, a top plate, a back plate, a front panel, and two side plates. The base plate is rectangular, and the two side plates are vertically fixed to opposite sides of the base plate. The back plate and the front panel are vertically fixed to the other two sides of the base plate. The top plate is fixedly connected above the back plate, the front panel, and the two side plates. The air inlet is usually located on the side plates for drawing in air.

[0004] However, the air inlet on the side panel will disrupt the overall appearance of the air compressor casing and affect the aesthetics of the equipment; moreover, the side air intake method has certain limitations on the installation location of the air compressor. In a small or enclosed installation environment, the air intake effect will be further limited, which will affect the working efficiency of the air compressor. Utility Model Content

[0005] To improve the aesthetics of the air compressor casing and reduce space constraints during air compressor use, this application provides an air compressor with a bottom air intake structure.

[0006] This application provides an air compressor with a bottom air intake structure, which adopts the following technical solution:

[0007] An air compressor with a bottom air intake structure includes a bottom plate, a top plate, a back plate, a front plate, and two side plates. The back plate, front plate, side plates, bottom plate, and top plate are connected to form a sealed working chamber. A first air intake channel for airflow is provided in the side plate, and a first air outlet is provided on the side wall of the first air intake channel near the working chamber. A second air intake hole is provided on the bottom plate, and air flows into the first air intake channel through the second air intake hole and enters the working chamber through the first air outlet.

[0008] By adopting the above technical solution, air flows into the first air intake channel through the second air intake hole on the bottom plate, and then flows into the working chamber of the air compressor through the first air outlet hole, providing a gas source for the air compressor. Since the second air intake hole is located on the bottom plate, the bottom air intake position is relatively concealed, which can improve the overall aesthetics and design of the air compressor, and reduce the space limitations during use.

[0009] Optionally, the lower end of the side plate is provided with a first air inlet hole, through which air flows into the first air intake channel and through the first air outlet hole into the working chamber.

[0010] By adopting the above technical solution, a first air inlet is added to the lower end of the side plate, which works in conjunction with the second air inlet to further increase the air intake and meet the air volume requirements of the air compressor.

[0011] Optionally, the first air outlet is located at the upper end of the side wall of the first air inlet channel near the working chamber.

[0012] By adopting the above technical solution, air enters the first air intake channel from the first and second air intake holes below, and then enters the working chamber from the first air outlet above the side plate. The air flows from bottom to top to form an airflow wall, which can block some of the noise transmitted through the airflow, thereby reducing the operating noise of the air compressor and improving the quietness of the air compressor.

[0013] Optionally, the panel has an installation opening, and the panel is provided with a door plate for sealing the installation opening; the door plate has a second air inlet channel for air flow, the upper end of the side wall of the second air inlet channel near the working chamber has a second air outlet, and the lower end of the door plate has a fourth air inlet. Air flows into the second air inlet channel through the fourth air inlet and enters the working chamber through the second air outlet.

[0014] By adopting the above technical solution, the second air intake channel further increases the air intake volume of the air compressor. At the same time, the air flows from bottom to top to form an airflow wall, which further blocks some of the noise transmitted through the airflow and improves the quietness of the air compressor.

[0015] Optionally, the door panel surface is flush with the panel surface.

[0016] By adopting the above technical solution, the door panel and the front panel are flush, which can further enhance the overall aesthetics and design of the air compressor.

[0017] Optionally, a cooling zone is provided on the inner side of the panel, and a third air inlet is provided at the bottom of the panel, through which air flows into the cooling zone.

[0018] By adopting the above technical solution, the air inlet of the internal cooling area is also located below the air compressor, which improves the overall aesthetics and design of the air compressor.

[0019] Optionally, multiple first air inlets, third air inlets, and fourth air inlets are provided. The multiple first air inlets are evenly distributed along the width direction of the side panel, the multiple third air inlets are evenly distributed along the width direction of the panel, and the multiple fourth air inlets are evenly distributed along the width direction of the door panel.

[0020] By adopting the above technical solution, the arrangement of multiple first air inlets, third air inlets and fourth air inlets can ensure that the air intake can cover the entire air intake channel, avoid local airflow being too strong or too weak, and at the same time enhance the structural strength of the side panels, front panels and door panels.

[0021] Optionally, dust filters can be detachably connected to the first, second, third, and fourth air inlets.

[0022] By adopting the above technical solution, the dust filter can filter the air entering the air compressor, reduce the risk of impurities entering, and extend the service life of the air compressor.

[0023] Optionally, sound-insulating foam is installed at the end of the side plate and the back plate near the working cavity.

[0024] By adopting the above technical solution, the sound-absorbing sponge absorbs mechanical vibration noise in the working chamber, reducing noise pollution during the operation of the air compressor.

[0025] In summary, this application includes at least one of the following beneficial technical effects:

[0026] 1. The first, second, third, and fourth air intakes are all located below the air compressor. The bottom air intake position is relatively concealed, which can improve the overall aesthetics and design of the air compressor, and has less space limitation when in use;

[0027] 2. By setting up a first air intake channel and a second air intake channel, air flows from bottom to top in the first air intake channel and the second air intake channel to form an airflow wall, which blocks some of the noise transmitted by the airflow and improves the quietness of the air compressor.

Figure 1 and Figure 2 It includes a base plate 1, a top plate 2, a back plate 3, a front plate 4, and two side plates 5. The back plate 3, the front plate 4, and the two side plates 5 are connected in sequence, and together with the connection of the base plate 1 and the top plate 2, they form a sealed working chamber 6.

[0035] Reference Figure 3 and Figure 4 The side plate 5 has a first air inlet channel 51 for airflow. A first air outlet 52 is located on the side wall of the first air inlet channel 51 near the working chamber 6, at the upper end of the side wall. The first air outlet 52 connects the first air inlet channel 51 to the working chamber 6. Two first air outlets 52 are provided, arranged along the width direction of the side plate 5. Multiple first air inlets 53 are evenly distributed along the width direction of the side plate 5 at the lower end of the side plate 5. Air enters the first air inlet channel 51 evenly through the multiple first air inlets 53, which also increases the structural strength of the side plate 5.

[0036] A second air inlet 11 is provided on the base plate 1, and the second air inlet 11 is connected to the first air intake channel 51. The second air inlet 11 is an oblong hole, and there are multiple second air inlets 11, which are evenly distributed on the base plate 1 along the width direction of the side plate 5. During operation, air enters the first air intake channel 51 through the first air inlet 53 and the second air inlet 11, and flows into the working chamber 6 through the first air outlet 52 for air compression.

[0037] Reference Figure 2 and Figure 4 The panel 4 has a cooling zone 41 on its inner side, and a cooling device is installed inside the cooling zone 41. A control panel 42 is also provided on the panel 4. Multiple third air inlets 43 are opened at the bottom of the panel 4, and the multiple third air inlets 43 are evenly distributed along the width direction of the panel 4. The third air inlets 43 are connected to the cooling zone 41. During operation, air flows into the cooling zone 41 through the third air inlets 43 for the intake of the internal cooling device.

[0038] The panel 4 has an installation opening, and a door panel 44 is provided on the panel 4 to block the installation opening. The door panel 44 is rotatably connected to the panel 4 via a pivot, and the door panel 44 can be opened or closed around the hinge point to realize the operation and maintenance of the equipment inside the working chamber 6.

These multiple fourth air inlets 443 increase both the air intake volume and the structural strength of the lower end of the door panel 44. During operation, air flows into the second air inlet channel 441 through the fourth air inlets 443 and into the working chamber 6 through the second air outlet 442 for air compression.

[0040] Sound-absorbing foam is installed at the end of the side plate 5 and the back plate 3 near the working chamber 6, which can reduce the transmission of noise when the air compressor is in use. In addition, when the air flows in the first air inlet channel 51 and the second air inlet channel 441, the air forms an airflow wall from bottom to top; the airflow wall can block some of the noise transmitted by the airflow, further reducing the operating noise of the air compressor and improving the quietness of the air compressor.

[0041] Dust filters are installed at the first air intake 53, the second air intake 11, the third air intake 43, and the fourth air intake 443.
