[0002] Portable integrated air compressors are usually used to compress air in various processing processes in order to produce compressed gas with higher pressure and faster flow rate.

[0003] The patent with patent announcement number CN221942649U relates to the field of air compressor technology. It is a mobile portable air compressor, including a high-pressure gas storage tank and a bracket fixedly connected to the bottom of the high-pressure gas storage tank, the bottom of the bracket is symmetrically installed with universal rollers, the end of the bracket is welded with a handrail frame, the handrail frame is symmetrically welded with connecting ears away from the root of the bracket, the end of the connecting ear is rotatably connected to a connecting arm, and a reduction motor is installed between the connecting arms. It can be extended by the movable end of the electric telescopic rod. During the rotation of the first connecting shaft and the second connecting shaft at both ends of the electric telescopic rod, the connecting arm cooperates with the connecting ear to swing downward, so that the driving wheel installed at the power output end of the reduction motor abuts against the ground, and then the driving wheel is driven to rotate by the power supply of the reduction motor to assist the movement of the air compressor. Therefore, it is very labor-saving in the process of manually pushing the air compressor to move.

[0004] In the above patent, satisfactory results are achieved through some relatively simple structures, which improves the portability of the air compressor in terms of movement and makes the movement of the device more labor-saving. However, if the device fails to replenish lubricating oil between the mechanical parts inside the compressor in time when working for a long time, it may cause increased wear between its internal parts and thus reduce its service life.

[0010] The bottom of the reciprocating screw rod is rotatably connected to the screw rod base, and the screw rod base is used to fix the reciprocating screw rod to enhance the stability of the device structure. The inclined top block is located on the movement trajectory of the telescopic top block, so that the rotation of the telescopic top block can drive the inclined top block to rotate. A return spring is provided between the telescopic top block and the inner wall rotating shaft, so that the telescopic top block can be compressed inwardly after contacting the inclined surface of the inclined top block so as not to drive the inclined top block to rotate together.

When the threaded slider slides upward, it drives the L-shaped pull rod to slide upward together. When the L-shaped pull rod slides upward, it drives the water valve control rod to rotate upward. After the water valve control rod rotates upward, the drain valve is opened, thereby realizing that the drain valve at the bottom of the device shell is opened every time the device is started to discharge the accumulated water formed inside the gas tank.

[0014] The present invention provides a portable integrated air compressor. It has the following beneficial effects: (1) This invention opens the refueling valve by contacting the valve control lever during the rotation of the rocker arm, thereby replenishing the lubricating oil inside the compressor through the refueling hose and the refueling valve during the startup of the device. Indirect refueling of the lubricating oil improves the utilization efficiency of the lubricating oil and avoids the friction of the internal parts of the compressor and reduces the service life. At the same time, when the lubricating oil in the lubricating oil box is about to run out, the float inside it slides downward and drives the limit lever and the limit block to slide through contact. The lubricating oil box pops out under the rebound force of the reset spring, so that the lubricating oil can be replenished quickly, avoiding the inability to replenish the lubricating oil inside the compressor in time after the lubricating oil is exhausted, and further improving the stability of the device during long-term operation.

[0015] (2) This invention drives the transmission ring and the threaded slider to slide upward by rotating the rocker arm. The movement of the threaded slider drives the inner wall shaft and the dust cleaning rubber to rotate through contact. When the dust cleaning rubber rotates, it cleans the dust at the heat dissipation port of the device shell through contact. At the same time, the rotation of the inner wall shaft drives the blades of the dust exhaust fan to rotate through the transmission wheel and the transmission pulley, thereby achieving the timely discharge of the cleaned dust from the inside of the device shell, avoiding the accumulation of dust inside the device after long-term use, thereby affecting the heat dissipation efficiency, and improving the stability of the device operation.

[0016] (3) In this invention, the threaded slider drives the water valve control rod to rotate upward through the L-shaped pull rod to open the drain valve, thereby realizing that the drain valve is opened every time before the device is started and enters the working state to discharge the accumulated water inside the gas tank, thereby avoiding rust caused by long-term accumulation of water inside the gas tank. At the same time, protection is formed by the safety valve, so that the device can only pass through the safety valve after the output device is connected and the angular top block pushes the air valve control rod by rotating the top rod to open the safety valve, thereby avoiding the leakage of compressed air in the gas tank caused by the operator's misoperation.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

A float 706 is provided on the inside, and a limit lever 707 is rotatably installed at the bottom of the inner wall of the lubricating oil box 701, and a limit block 708 is rotatably installed on the inner wall of the device housing 1. By rotating the rocker arm 702, the valve control rod 704 is contacted during the rotation to open the refueling valve 703, so that the lubricating oil inside the compressor 3 is replenished through the refueling hose 705 and the refueling valve 703 during the startup of the device. Indirect replenishment of lubricating oil improves the utilization efficiency of the lubricating oil and avoids friction between the internal parts of the compressor 3 and reduces the service life. At the same time, when the lubricating oil inside the lubricating oil box 701 is about to run out, the float 706 inside it slides downward and drives the limit lever 707 and the limit block 708 to slide through contact, and the lubricating oil box 701 pops out under the rebound force of the reset spring, so that the lubricating oil can be quickly replenished.

[0021] A return spring is provided between the lubricating oil box 701 and the device housing 1, so that the lubricating oil box 701 can pop out automatically when the lubricating oil inside the lubricating oil box 701 is exhausted, thereby making it convenient for the operator to replenish the lubricating oil. The valve control rod 704 is located on the movement trajectory of the rotating rocker arm 702, so that when the rotating rocker arm 702 is transmitted upward, it can drive the valve control rod 704 to deflect by contact. The limit lever 707 is located on the movement trajectory of the float 706, so that when the float 706 moves downward, it can drive the limit lever 707 to rotate by contact. The limit block 708 is located on the movement trajectory of the limit lever 707, so that the rotation of the limit lever 707 can drive the limit block 708 to rotate by contact. The limit block 708 contacts the lubricating oil box 701, so that a limit is formed between the limit block 708 and the lubricating oil box 701 to limit the movement of the lubricating oil box 701.

[0022] During operation: When the device enters the working state, the motor 6 is first started. After the motor 6 is started, it drives the motor shaft to rotate. The rotation of the motor shaft drives the rotating pendulum 702 to rotate. During the rotation of the rotating pendulum 702, it will rotate in the upward direction under the action of centrifugal force. When the rotating pendulum 702 rotates upward, it drives the valve control rod 704 to rotate through contact to open the refueling valve 703. After the refueling valve 703 is opened, the lubricating oil in the lubricating oil box 701 flows into the interior of the compressor 3 through the refueling hose 705 and the refueling valve 703, thereby realizing the replenishment of lubricating oil to the interior of the compressor 3 when the device is started, avoiding the problem of insufficient lubrication inside the compressor 3. This causes accelerated wear of its internal parts. At the same time, when the lubricating oil inside the lubricating oil box 701 is about to run out, the float 706 inside it will lose the buoyancy of the lubricating oil and slide downward. When the float 706 slides downward, it drives the limit lever 707 to rotate through contact. The rotation of the limit lever 707 drives the limit block 708 to rotate through contact. After the limit block 708 rotates, it disengages from the lubricating oil box 701 to contact the limit, so that the lubricating oil box 701 slides forward and pops out under the rebound force of the reset spring, so that the operator can replenish the lubricating oil box 701 in time when the lubricating oil is about to run out, so as to improve the stability of the device during long-term operation.
