Description

Technical Field

[0001] The utility model relates to a closed air compressor structure with remote filtering, in particular to an air compressor unit connected with an external filter assembly. Background Art

[0002] Existing air compressors or inflators are mainly used in pneumatic tools, vehicle tires or various inflatable devices as a source of inflation gas; therefore, in the field of DIY, air compressors or inflators have become necessary tools in the workplace or for general home repairs, and have become necessary equipment for emergency rescue of vehicle tires.

[0003] As for the working principle of the air compressor or inflator, it is mainly that the internal motor directly drives the crankshaft, causing the crankshaft to rotate, and then drives the connecting rod to make the piston move up and down reciprocatingly, causing the cylinder volume to change, and the pressurized gas is compressed and exhausted to complete the entire air compression process; therefore, during the entire compression and exhaust process, due to the change in cylinder volume, the compressed air passes through the one-way valve mechanism (check valve), and the pressurized gas is output through the air nozzle by a hose, and then an object can be inflated.

[0004] However, in the existing field of application of small and medium-sized air compressors or inflators for tire inflation, there is no filtering device that can filter dust, grit and water vapor; therefore, when in a harsh environment, it is often exposed to dust, grit and excessive air humidity, causing serious impact on the air compressor or inflator. Once dust and grit enter the inflator or air compressor unit, the motor will be the first to be damaged, and the cylinder body will also be affected by dust and grit, which will inevitably cause rapid wear and damage between the piston and the cylinder wall; in addition, if high-humidity water vapor enters the air compressor or inflator unit, it will inevitably cause the motor, piston and cylinder to rust, causing the service life of the air compressor or inflator to be greatly reduced. Utility Model Content

[0005] In order to solve the above problems, the main purpose of the utility model is to provide a closed air compressor structure with remote filtration, which can filter dust, sand and water vapor entrained in the external harsh environment, so as to increase the service life of the entire air compressor or inflator.

[0006] To achieve the above-mentioned purpose, the utility model provides a closed air compressor structure with remote filtering, including a bearing seat, an air compressor unit and a cover plate. The bearing seat is provided with a containing space inside, and the bearing seat is provided with a breathable grille on at least one side wall thereof, so that external air can enter the containing space through the breathable grille; the air compressor unit is arranged in the containing space of the bearing seat, and is provided with at least one air inlet end and at least one air outlet end, the air inlet end is connected with a first conduit and communicated with a filter assembly, so that the filter assembly is connected with the outside of the air compressor unit and is relatively located in the containing space of the bearing seat, and the air outlet end is connected with a second conduit and communicated with an air outlet valve head, so that the air outlet valve head is connected with the outside of the air compressor unit and relatively extends out of the containing space of the bearing seat; the cover plate is combined with the top of the bearing seat and closes the containing space, and the cover plate is provided with at least one opening, so that the air outlet valve head is exposed outside the opening.

[0007] Thus, when the air compressor unit is started, external air will be forcibly sucked in from the filter assembly, that is, it has a forced air intake function; that is, it passes through the filter assembly and the first conduit in sequence into the air compressor unit, and then the air compressor unit exhausts the compressed air through the second conduit and the outlet valve head in sequence to complete the entire intake, compression and exhaust operations.

[0008] The main technical effect of the utility model is that, by connecting the air compressor unit with an external filter assembly, the dust, grit and water vapor in the air can be effectively filtered through the external filter assembly, thereby effectively preventing the dust, grit and water vapor entrained in the air from entering the air compressor unit and causing a series of damage and rust to the motor and cylinder body, thereby effectively achieving the purpose of prolonging the service life of the air compressor, and making the air compressor suitable for various harsh environments (for example: the air compressor can be suitable for use in beaches, seaside environments, etc.).

[0009] At the same time, the air compressor unit and the filter assembly can be set up through the bearing seat, and the accommodating space is closed by the cover plate, so that the air compressor unit and the filter assembly can be completely hidden in the bearing seat, avoiding the air compressor unit and the filter assembly from being directly exposed to the sun and rain, further effectively improving the service life of the air compressor, and making the air compressor more suitable for various environments.
