Description

Technical Field

[0001] This application relates to the technical field of air compressors, and particularly relates to a multi-purpose air compressor. Background Art

[0002] Although there are many types of general reciprocating piston air compressors, their structures are basically the same. That is, the motor outputs power through the crankshaft, and the connecting rod drives the piston to reciprocate in the cylinder to compress the gas for work to produce compressed air. Such a reciprocating piston air compressor generally includes a motor, a connecting rod, a cylinder frame, a cylinder liner, a cylinder head, and an air storage tank. The rotation of the motor drives the connecting rod to reciprocate in the cylinder frame. The connecting rod is connected to the piston, and the piston compresses the gas with the reciprocating movement of the connecting rod and conveys the compressed gas into the air storage tank.

[0003] The air compressor can be installed on the vehicle chassis to provide a gas source for sealed containers such as air shock absorbers. Currently, the air compressors installed on the vehicle chassis are mainly used on land, that is, when the vehicle does not wade through water or the like. However, when the vehicle wades through water and the air compressor is underwater, it cannot be used, which limits the usage scenarios of the air compressor. Summary of the Invention

[0025] The following will describe a multi-purpose air compressor of the present application in detail with reference to the accompanying drawings. Without conflict, the features in the following embodiments may be combined with each other.

[0026] Please refer to Figures 1 to 5 As shown, a multi-purpose air compressor includes a cylinder frame 1, on which there are a convex seat 2 and an air inlet 3. The convex seat 2 is circular, the air inlet 3 penetrates the convex seat 2, the air inlet 3 is coaxially arranged with the convex seat 2, and the air inlet 3 communicates the inside of the cylinder frame 1 with the outside.

[0027] The convex seat 2 can be connected to a hose. When the air compressor is underwater, the hose extends out of the water surface, and air can enter the cylinder frame 1 through the hose, providing an air inlet source for the air compressor, enabling the air compressor to be used not only on land but also underwater, providing an air source for sealed containers such as air shock absorbers, making the air compressor applicable to different scenarios and expanding the uses of the air compressor.

[0028] After a large number of tests by the applicant, when the wading depth of the vehicle is within about 1.5 meters, by using this air compressor, an air source can be provided for the air compressor through a hose, and then an air source can be provided for sealed containers such as air shock absorbers on the vehicle. When in use, when the vehicle wades through water, the hose is manually inserted onto the boss 2, and the end of the hose away from the boss 2 is fixed on the vehicle, so that it can connect the inside and outside of the air compressor to provide an air source for the air compressor, enabling the air compressor to be used underwater.

[0029] In this embodiment, there are multiple bosses 2 and multiple air inlets 3, and the air inlets 3 correspond to the bosses 2 one by one. A detachable air inlet seat 4 is assembled on the air inlets 3.

[0030] The air inlet seat 4 includes a connecting body 5 and a seat body 6 which are integrally provided. The connecting body 5 is detachably connected to the air inlet 3. An air inlet passage 7 is provided on the connecting body 5, and the air inlet passage 7 passes through the air inlet 3. By providing multiple air inlets 3 and the volume of the air inlet passage 7 being smaller than the volume of the air inlet 3, while ensuring the air intake volume, the noise source can be reduced, and the noise of the air compressor can be effectively reduced.

[0031] In this embodiment, the connecting body 5 and the air inlet 3 are connected by threads, which is convenient for the disassembly and assembly of the two.

[0032] The seat body 6 is provided with a receiving cavity 8 with one end open. The receiving cavity 8 is coaxially communicated with the air inlet passage 7, and the receiving cavity 8 is coaxially arranged with the air inlet 3.

[0033] The cross-section of the air inlet passage 7 is polygonal, circular, elliptical or irregular. In this embodiment, the cross-section of the air inlet passage 7 is hexagonal.

[0034] When the air inlet seat 4 is assembled on the air inlet 3, the seat body 6 abuts against the boss 2.

[0035] The seat body 6 is provided with a detachable air inlet cover 9. The air inlet cover 9 includes a cover body and an assembly body. The cover body covers the receiving cavity 8. A filter cotton 10 is provided between the receiving cavity 8 and the cover body. The filter cotton 10 covers the air inlet passage 7, and the cover body is connected to the seat body 5 through the assembly body.

[0036] Specifically, the cover body includes a cover plate 11 and an annular plate 12 which are integrally provided. The annular plate 12 is arranged on the outer periphery of the seat body 5 and an air inlet gap is formed between the two. The filter cotton 10 is provided between the cover plate 11 and the receiving cavity 8.

[0037] The assembly includes several struts 13, which are connected to the annular plate 12. The struts 13 are arranged around the outer periphery of the seat body 6. Hooks 14 are provided at one end of some of the struts 13 away from the cover plate 11, and the hooks 14 hook the seat body 6. In this embodiment, the hooks 14 are symmetrically arranged according to the center line of the cover plate 11. Generally, the number of the hooks 14 is one pair. Such an arrangement facilitates the disassembly and assembly between the air inlet cover 9 and the seat body 6.

[0038] In order to better assemble the cylinder frame 1 with other components, such as connecting rods, cylinder liners, etc., the cylinder frame 1 includes a first cylinder frame 15 and a second cylinder frame 16 which are separately arranged. The first cylinder frame 15 and the second cylinder frame 16 can also be assembled by screws. The convex seat 2 and the air inlet 3 are arranged on the second cylinder frame 16. A crankshaft through hole for the crankshaft to pass through is provided on the first cylinder frame 15. The specific usage mode is the same as that of the prior art and will not be elaborated here.

[0039] The air compressor is installed on the vehicle chassis. When the vehicle is running on land, the outside air successively passes through the air inlet gap, the filter cotton 10, and the air inlet passage to provide air source for the air compressor. When the vehicle wades through water, the air compressor is underwater. Remove the air inlet seat 4, the filter cotton 10, and the air inlet cover 9, and then connect a hose to the convex seat 2. Fix the end of the hose away from the convex seat 2 on the vehicle and expose it above the water surface. The outside air provides air source for the air compressor through the hose.

[0040] The above are only the preferred embodiments of the present application, and do not impose any form of limitation on the present application. Although the present application has been disclosed above with the preferred embodiments, it is not intended to limit the present application. Any person skilled in the art can make some changes or modifications to the equivalent embodiments by using the disclosed technical content within the scope of the technical solution of the present application. However, as long as it does not depart from the technical content of the present application, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present application still fall within the scope of the technical solution of the present application.
