Description

Technical Field

[0001] The present invention relates to the technical field of air compressors, and more specifically, to a double-cylinder air compressor. Background Art

[0002] An air compressor, or air compressor in full, is a mechanical device used to compress gas. Its working principle is to increase the pressure of compressed air by compressing it, thereby generating compressed air with a certain pressure. This compressed air can be used in various industrial and commercial applications, such as pneumatic tools, equipment cleaning, fuel nozzles, etc. Air compressors are mainly divided into scroll air compressors, piston air compressors, screw air compressors, centrifugal air compressors, etc. Among them, a twin-cylinder air compressor refers to a reciprocating piston air compressor equipped with two sets of pistons running simultaneously. This design doubles the air supply of a twin-cylinder air compressor compared to a single-cylinder air compressor of the same type. Twin-cylinder air compressors usually run more smoothly than single-cylinder air compressors, with relatively less vibration and noise.

[0003] When a double-cylinder air compressor is in use, a large amount of water will accumulate inside the gas tank after long-term use, and the accumulated water will erode the inside of the gas tank, affecting the service life of the gas tank, thereby reducing the service life of the double-cylinder air compressor. Therefore, it is necessary to regularly open the drain valve on the lower side of the gas tank to drain the accumulated water inside the gas tank. However, when discharging the accumulated water inside the gas tank of the existing double-cylinder air compressor, the double-cylinder air compressor needs to be shut down first, and then the drain valve can be opened to drain the accumulated water in the gas tank, affecting the working efficiency of the double-cylinder air compressor. When the accumulated water in the gas tank is discharged, the compressed air in the gas tank will also be discharged at the same time, further reducing the working efficiency of the double-cylinder air compressor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] (1) This scheme sets a drainage component, drives the No. 1 straight plate to move to one side through the control structure, thereby driving the No. 1 through hole to move away from the connecting hole, so that the connecting hole and the No. 1 through hole are offset, thereby blocking the connecting hole, and then continues to drive the No. 1 straight plate to move to one side, and at the same time drives the No. 2 straight plate to move to the other side through the conversion structure, thereby driving the No. 2 through hole to move in the direction of the drainage hole, so that the No. 2 through hole and the drainage hole overlap, and then the drainage hole is opened, so that the accumulated water in the gas tank is discharged from the drainage hole. At the same time, because the No. 1 straight plate blocks the connecting hole, the compressed air in the gas tank will not be discharged at the same time as the accumulated water. Therefore, the air compressor does not need to be shut down, and the accumulated water in the gas tank can be discharged, thereby improving the working efficiency of the double-cylinder air compressor.

[0019] (2) This solution sets a limit assembly, drives one side of the adjustment rod to rotate around the fixed axis through the adjustment block, and drives the pawl corresponding to the adjustment rod to move away from the ratchet through the rotating ring, so that the pawl is separated from the ratchet, and drives the pawl on the other side to engage with the ratchet through the spring, so that the ratchet can only move in the same direction, thereby preventing the air compressor from driving the handle to drive the No. 1 gear to rotate when moving, thereby improving the practicality of the drainage assembly.

[0020] (3) This scheme sets up a ventilation component. When the No. 2 straight plate moves to the other side, it also drives the sliding plate to move in the direction of the No. 2 gear in the L-shaped slide groove, thereby driving the No. 3 rack and the No. 2 rack to move in the opposite direction through the No. 2 gear, and at the same time drives the sliding baffle to move, so that the ventilation groove moves toward the ventilation pipe, thereby connecting the ventilation pipe with the water tank, allowing external air to enter the air tank from the ventilation pipe, so that the accumulated water can be better discharged from the drainage hole, thereby increasing the drainage speed of the drainage hole, thereby improving the working efficiency of the drainage component, and further improving the working efficiency of the air compressor.

A control structure 58 is provided at one end of the straight plate No. 1 510, and a conversion structure 59 is provided at the other end of the straight plate No. 1 510.

[0040] like Figure 2 , Figure 3 As shown, one end of the outer surface of the water tank 51 is fixedly connected to the control box 52, the control structure 58 includes a No. 1 rack 581 fixedly connected to one end of the No. 1 straight plate 510, and the No. 1 rack 581 extends into the control box 52, and a No. 1 mounting groove 582 is provided inside the control box 52 near the bottom of the No. 1 rack 581, and a No. 1 gear 583 is rotatably connected inside the No. 1 mounting groove 582, and the No. 1 gear 583 is meshed with the No. 1 rack 581, and one side of the outer surface of the No. 1 gear 583 is fixedly connected to a turning handle 584 that passes through the control box 52.

[0041] like Figure 2 , Figure 3As shown, the other end of the outer surface of the water storage tank 51 is fixedly connected to a conversion box 53, and the conversion structure 59 includes a No. 1 straight rod 591 fixedly connected to the other end of the No. 1 straight plate 510, and one end of the No. 2 straight plate 512 is fixedly connected to the No. 2 straight rod 592, and the No. 1 straight rod 591 and the No. 2 straight rod 592 both extend into the conversion box 53, and a No. 1 rotating shaft 593 is rotatably connected to the center position inside the conversion box 53, and telescopic connecting rods 594 are fixedly connected to the upper and lower sides of the outer circular surface of the No. 1 rotating shaft 593, and one end of the lower surface of the No. 1 straight rod 591 and one end of the upper surface of the No. 2 straight rod 592 are fixedly connected to a connecting seat 595, and one end of the two telescopic connecting rods 594 are rotatably connected to the two connecting seats 595 respectively.

[0042] like Figure 1 , Figure 2 As shown, a movable handle 3 is fixedly connected to the side of the upper side of the outer circumference of the gas storage tank 1 away from the air compressor body 2, and moving wheels 4 are provided on both sides of the lower side of the outer circumference of the gas storage tank 1 away from the water tank 51.

[0043] When in use, first start the air compressor body 2, suck the external air into the air compressor body 2 for compression, then store the compressed air in the air storage tank 1, and then move the handle 3 and the action wheel 4 to move the air compressor to a suitable position for easy use.

[0044] However, after the air compressor is used for a long time, a large amount of water will accumulate in the gas tank 1, and the accumulated water will corrode the inside of the gas tank 1. It is necessary to drain the accumulated water in the gas tank 1. However, when draining, the air compressor needs to be shut down first, which reduces the working efficiency of the double-cylinder air compressor. When draining, the compressed air in the gas tank 1 will be discharged at the same time, further reducing the working efficiency of the double-cylinder air compressor. Therefore, a drainage component 5 is provided. First, the water in the gas tank 1 is drained by overlapping the connecting hole 54 and the first through hole 511. The accumulated water is drained into the water storage tank 51, and then the turning handle 584 in the control structure 58 is rotated to drive the No. 1 gear 583 to rotate in the No. 1 mounting groove 582, thereby driving the No. 1 rack 581 to move to one side, and at the same time driving the No. 1 straight plate 510 to move to one side in the No. 1 slide groove 56, thereby driving the No. 1 through hole 511 to move away from the connecting hole 54, so that the connecting hole 54 is staggered with the No. 1 through hole 511, and at the same time the connecting hole 54 is blocked by the No. 1 straight plate 510, thereby preventing compressed air from entering the air storage tank. 1, and then continue to rotate the No. 1 gear 583, thereby driving the No. 1 straight plate 510 to continue to move to one side, and at the same time driving the No. 1 straight rod 591 to move to one side, and then through the upper connecting seat 595, at the same time driving the upper telescopic connecting rod 594 to rotate around the No. 1 rotating shaft 593 to one side, thereby driving the lower telescopic connecting rod 594 to rotate around the No. 1 rotating shaft 593 to the other side, and then through the lower connecting seat 595, driving the No. 2 straight rod 592 to move to the other side, and at the same time driving the No. 2 straight plate 512 to rotate on the No. 2 sliding seat. The second through hole 513 is moved toward the drain hole 55 so that the second through hole 513 coincides with the drain hole 55, and the drain hole 55 is opened, so that the accumulated water in the gas tank 1 is discharged from the drain hole 55. At the same time, because the connecting hole 54 is blocked by the first straight plate 510, the compressed air in the gas tank 1 is not discharged at the same time as the accumulated water. Therefore, the air compressor does not need to be shut down and the accumulated water in the gas tank 1 can be discharged, thereby improving the working efficiency of the double-cylinder air compressor.

[0045] After the accumulated water in the gas tank 1 is discharged, the handle 584 is rotated in the reverse direction to drive the No. 1 gear 583 to rotate in the reverse direction, thereby driving the No. 1 straight plate 510 to move to the other side, so that the No. 1 through hole 511 moves in the direction of the connecting hole 54, and then the connecting hole 54 and the No. 1 through hole 511 coincide with each other. Before that, the No. 2 straight plate 512 can be driven to move to one side through the conversion structure 59, so that the No. 2 through hole 513 moves away from the drainage hole 55, so that the No. 2 through hole 513 is staggered with the drainage hole 55, and then the water tank 51 is closed.

[0046] like Figure 3 , Figure 4 , Figure 5As shown, a limit assembly 6 is provided on one side of the outer circumferential surface of the turning handle 584 close to the number one gear 583, and the limit assembly 6 includes a number two mounting groove 61 opened in the control box 52 near the number one gear 583, a ratchet 62 is fixedly connected to one side of the outer circumferential surface of the turning handle 584, and the ratchet 62 is located inside the number two mounting groove 61, and a fixed shaft 64 is fixedly connected to the inside of the number two mounting groove 61 below the ratchet 62, and the outer circumferential surface of the fixed shaft 64 is rotatably connected to two rotating rings 65, and the upper sides of the outer circumferential surfaces of the two rotating rings 65 are fixedly connected to pawls 66, and the two pawls 66 are respectively located on both sides below the ratchet 62, and a spring 67 is provided between the two pawls 66 and the inner wall of the number two mounting groove 61.

[0047] like Figure 4 , Figure 5 As shown, a No. 3 mounting groove 63 is opened at the lower end of the inner wall of the No. 2 mounting groove 61, and an adjustment block 68 is slidably connected inside the No. 3 mounting groove 63. The outer circular surfaces of the two rotating rings 65 away from the pawl 66 are fixedly connected with adjustment rods 611, and the two adjustment rods 611 are located on both sides of the adjustment block 68.

[0048] like Figure 5 As shown, both ends of the outer surface of the adjustment block 68 are fixedly connected to the limit plate 69, one end of the outer surface of the limit plate 69 is fixedly connected to the third straight rod 610 that passes through the control box 52, and one end of the third straight rod 610 passes through the adjustment block 68 and extends into the control box 52, and one end of the outer circular surface of the third straight rod 610 is fixedly connected to an anti-slip sleeve.

[0049] In the above embodiment, the No. 1 gear 583 is rotated to drive the No. 1 straight plate 510 to move to one side, thereby blocking the connecting hole 54, and then the No. 1 gear 583 is continued to be rotated to drive the No. 1 straight plate 510 to move to one side, and at the same time, the No. 2 straight plate 512 is driven to move to the other side through the conversion structure 59, so that the No. 2 through hole 513 coincides with the drainage hole 55 to open the drainage hole 55, thereby discharging the accumulated water from the drainage hole 55. However, when pushing the air compressor, the movement of the air compressor itself easily drives the turning handle 584 to shake, thereby driving the No. 1 gear 583 to rotate, so that the No. 1 straight plate 510 will move autonomously and block the connecting hole 54, reducing the practicality of the drainage component 5. Therefore, a limit assembly 6 is provided, and the No. 3 straight rod 610 drives the adjustment block 68 to move in the No. 3 mounting groove 63, and the anti-slip sleeve is used to facilitate the manual driving of the No. 3 straight rod 610 to move, and at the same time, two limit assemblies are used. The positioning plate 69 limits the movement of the adjustment block 68, and then drives the adjustment rod 611 on one side to rotate around the fixed shaft 64 through the adjustment block 68, and at the same time drives the pawl 66 corresponding to the adjustment rod 611 to move in the direction away from the ratchet 62 through the rotating ring 65, so that the pawl 66 is separated from the ratchet 62, and then drives the pawl 66 on the other side to move toward the ratchet 62 through the spring 67, so that the pawl 66 on the other side is engaged with the ratchet 62, so that the ratchet 62 can only move in the same direction, and then the turning handle 584 can only move in the same direction, so that the turning handle 584 drives the No. 1 gear 583 to rotate, and drives the No. 1 straight plate 510 to move to the end point on one side. Since the turning handle 584 can only move in the same direction at the same time, the turning handle 584 is fixed, thereby preventing the air compressor from driving the turning handle 584 to drive the No. 1 gear 583 to rotate when moving, thereby improving the practicality of the drainage assembly 5.

[0050] like Figure 3 , Figure 4 , Figure 6 , Figure 7As shown, a ventilation assembly 7 is provided on one side of the outer surface of the water storage tank 51, and the ventilation assembly 7 includes a ventilation pipe 71 fixedly connected to the upper side of one side of the outer surface of the water storage tank 51, and one end of the ventilation pipe 71 is connected to the upper end of the inner wall of the water storage tank 51, and a third slide groove 76 is provided inside the shell of the water storage tank 51 near the side of the ventilation pipe 71, and a sliding baffle 77 is slidably connected inside the third slide groove 76, and a ventilation groove 79 is provided on one side of the outer surface of the sliding baffle 77 near the ventilation pipe 71, and the inner wall of the second slide groove 57 near the third slide An L-shaped slide groove 72 is provided on one side of the groove 76, and a slide plate 73 is slidably connected inside the L-shaped slide groove 72. A No. 2 rack 74 is fixedly connected to the side of the upper surface of the slide plate 73 away from the No. 2 slide groove 57. A No. 1 connecting groove 710 is provided between the No. 3 slide groove 76 and the L-shaped slide groove 72. A No. 2 gear 75 is rotatably connected inside the No. 1 connecting groove 710, and the No. 2 gear 75 is meshingly connected to the No. 2 rack 74. A No. 3 rack 78 is fixedly connected to the lower surface of the sliding baffle 77, and the No. 3 rack 78 is meshingly connected to the No. 2 gear 75.

[0051] like Figure 6 , Figure 7 As shown, a fixed component 8 is provided on one side of the L-shaped slide groove 72, and a No. 4 slide groove 81 is opened on the side of the upper end of the inner wall of the fixed component 8 away from the No. 2 gear 75, and a No. 4 rack 82 is slidably connected inside the No. 4 slide groove 81, and a moving block 83 is fixedly connected to one side of the lower surface of the No. 4 rack 82, and the moving block 83 is slidably connected in the L-shaped slide groove 72, and a No. 5 slide groove 84 is opened on the side of the inner wall of the No. 3 slide groove 76 close to the No. 4 slide groove 81, and a tooth plate 85 is slidably connected inside the No. 5 slide groove 84, and a No. 2 connecting groove 87 is opened between the No. 5 slide groove 84 and the No. 4 slide groove 81, and a No. 3 gear 86 is rotatably connected inside the No. 2 connecting groove 87, and the No. 3 gear 86 is meshed with the No. 4 rack 82 and the tooth plate 85.

[0052] In the above embodiment, the accumulated water in the gas tank 1 is discharged through the drainage hole 55. However, when draining, because only the drainage hole 55 in the water tank 51 is connected to the outside, the drainage speed of the drainage hole 55 is slow, which reduces the working efficiency of the drainage component 5 and affects the working efficiency of the double-cylinder air compressor. Therefore, a ventilation component 7 is provided. When the No. 2 straight plate 512 moves to the other side, it also drives the slide plate 73 to move in the direction of the No. 2 gear 75 in the L-shaped slide groove 72, thereby driving the No. 2 rack 74 to move in the direction of the No. 2 gear 75, so that the No. 2 rack 74 is meshed with the No. 2 gear 75, thereby driving the No. 2 gear 75 to rotate in the No. 1 connecting groove 710, and then driving the No. 3 rack 78 and the No. 2 rack 74 to move in the opposite direction, and at the same time driving the slide plate 73 to move in the L-shaped slide groove 72. The movable baffle 77 moves in the L-shaped slide groove 72, so that the ventilation groove 79 moves toward the ventilation pipe 71, and then the ventilation pipe 71 is connected with the water tank 51, so that the external air enters the air tank 1 from the ventilation pipe 71, so that the accumulated water can be better discharged from the drainage hole 55, thereby improving the drainage speed of the drainage hole 55, thereby improving the working efficiency of the drainage component 5, and further improving the working efficiency of the air compressor. When the No. 2 straight plate 512 moves to one side, the No. 2 rack 74 is driven by the slide plate 73 to move away from the No. 2 gear 75, thereby driving the sliding baffle 77 to move in the opposite direction, so that the ventilation groove 79 moves away from the ventilation pipe 71, thereby blocking the ventilation pipe 71 through the sliding baffle 77 to prevent the water tank 51 from leaking.

[0053] The cam 76 is actuated to move the air filter 77 in a direction away from the second gear 75 so that the air filter 76 is in a position to move the air filter 77 and ...

[0054] like Figure 4 , Figure 8 , Fig. 9As shown, a monitoring component 9 is provided on one side of the outer surface of the water tank 51 near the ventilation pipe 71, and the monitoring component 9 includes a water level observation tube 91 fixedly connected to the outer surface of the water tank 51 near the ventilation pipe 71, and the upper and lower ends of the water level observation tube 91 are connected to the inner wall of the water tank 51, a liquid level sensor 92 is provided on the upper side of the water level observation tube 91, and the liquid level sensor 92 is fixedly connected to the outer surface of the water tank 51, a single-chip microcomputer 93 is fixedly connected to the position of the liquid level sensor 92 near the outer cylindrical surface of the gas storage tank 1, and the single-chip microcomputer 93 is electrically connected to the liquid level sensor 92, a controller 94 is fixedly connected to the position of the outer cylindrical surface of the gas storage tank 1 near the single-chip microcomputer 93, and the controller 94 is electrically connected to the single-chip microcomputer 93, and an alarm light 95 is fixedly connected to one side of the outer cylindrical surface of the gas storage tank 1 near the controller 94, and the alarm light 95 is electrically connected to the controller 94.

[0055] In the above embodiment, the first gear 583 is rotated by rotating the handle 584, thereby blocking the connecting hole 54, and then the handle 584 is further rotated to open the drain hole 55, thereby draining the accumulated water in the gas tank 1. However, when the air compressor is in use, it is impossible to determine the amount of water accumulated in the gas tank 1, so that the user cannot determine when to open the drain hole 55 to drain the accumulated water in the gas tank 1. Therefore, a monitoring component 9 is provided, and the upper and lower ends of the water level observation tube 91 are connected to the inner wall of the water tank 51, so that the liquid level inside the water level observation tube 91 can be monitored. It is parallel to the liquid level inside the water tank 51, so that the user can judge the amount of water accumulated in the water tank 51 by observing the liquid level in the water level observation tube 91. At the same time, after the liquid level in the water level observation tube 91 rises to a certain level, the liquid level sensor 92 transmits a signal to the single-chip microcomputer 93, and then the single-chip microcomputer 93 processes the signal and transmits the processed signal to the controller 94, and then the controller 94 controls the alarm light 95 to turn on, so that the user can promptly detect that there is too much water in the gas tank 1 and needs to start the drainage component 5.

[0056] Instructions for use: Through the air compressor body 2, the external air is sucked into the air compressor body 2 for compression, and then the compressed air is stored in the air tank 1. The air compressor can be moved to a suitable position by the cooperation of the moving handle 3 and the action wheel 4, and then the amount of water accumulated in the water tank 51 is monitored by the monitoring component 9. When the amount of water accumulated in the air tank 1 is too much, the alarm light 95 is turned on, and then the adjustment block 68 is driven to move by the No. 3 straight rod 610, so that the limit component 6 adjusts the turning handle 584 to the state of opening the drain hole 55, and then the turning handle 584 is rotated, so as to drive the No. 1 through hole 511 to move away from the connecting hole 54 through the No. 1 straight plate 510, so that the connecting hole 54 is staggered with the No. 1 through hole 511 to block the connecting hole 54. , and then the conversion structure 59 drives the No. 2 straight plate 512 to drive the No. 2 through hole 513 to move toward the direction of the drainage hole 55, so that the No. 2 through hole 513 coincides with the drainage hole 55 to open the drainage hole 55, and at the same time drives the slide plate 73 to move toward the direction of the No. 2 gear 75, thereby driving the No. 2 rack 74 to move toward the direction of the No. 2 gear 75, so that the No. 2 rack 74 is meshed with the No. 2 gear 75, driving the No. 2 gear 75 to rotate, thereby driving the No. 3 rack 78 and the No. 2 rack 74 to move in the opposite direction, so that the sliding baffle 77 drives the ventilation groove 79 to move toward the ventilation pipe 71, so that the ventilation pipe 71 is connected with the water storage tank 51, so that the external air enters the air storage tank 1 from the ventilation pipe 71, thereby discharging the accumulated water in the water storage tank 51 from the drainage hole 55.
