Description

Technical Field

[0001] The present invention belongs to the technical field of air compressors, and more specifically, relates to an air compressor device with high efficiency in cooling and noise reduction. Background Art

[0002] An air compressor is a device used to compress gases. The air compressor is similar in structure to a water pump. Most air compressors are reciprocating pistons, rotary vane or rotary screw types. Air compressors can be divided into three categories according to the working principle: positive displacement, dynamic (velocity type or turbomachine type), and thermal compressors.

[0003] During the operation of existing air compressors, continuous vibration occurs, resulting in relatively high noise, and long-term vibration easily causes damage to internal components.

[0004] To solve the above problems, an air compressor device with high efficiency in cooling and noise reduction is proposed in this application. Summary of the Invention

[0005] In view of the problems in the related art, the present invention provides an air compressor device with high efficiency in cooling and noise reduction to overcome the above-mentioned technical problems existing in the related art.

[0006] To achieve the above object, the present invention adopts the following technical solutions:

[0007] An air compressor device with high efficiency in cooling and noise reduction includes a machine shell. An oil chamber is provided on the side of the machine shell. A partition is fixedly installed on the inner wall of the oil chamber. An oil discharge pipe is installed at the bottom of the machine shell. A plurality of oil injection pipes are installed on the top inner wall of the oil chamber.

[0008] A motor is fixedly installed on one side of the machine shell. A spiral rotor is rotatably connected to the inner wall of the machine shell. The output shaft of the motor is fixedly connected to the corresponding spiral rotor.

[0009] Four support and shock absorption mechanisms, including four support rods. The four support rods are slidably installed at the bottom of the machine shell. A cushion plate is fixedly installed at the bottom end of the support rod.

[0010] Four oil injection mechanisms, including four oil injection boxes. The oil injection boxes are fixedly installed at the bottom of the partition. The oil injection boxes are slidably connected to the corresponding support rods. An oil suction pipe is installed on one side of the oil injection box. A throttle cylinder is installed on the oil suction pipe. A through hole is opened at the top of the oil injection box, and the through hole penetrates the partition.

[0011] An air inlet pipe is fixedly installed on the top of the machine shell. An exhaust pipe is installed on the top of the machine shell. A plurality of heat dissipation fins are installed on both the top and bottom of the machine shell, and the heat dissipation fins extend into the oil chamber.

[0012] Preferably, the support and shock absorption mechanism further includes a buffer spring. The buffer spring is fixedly installed on the top of the backing plate. A damping box is fixedly installed on the top of the backing plate, and the damping box is fixedly connected to the bottom of the casing.

[0013] The backing plate and the buffer spring buffer and reset between the damping box and the support rod, and at the same time support the support rod.

[0014] Preferably, the support rod is slidably connected to the damping box. Three damping plates are fixedly installed on the support rod, and the damping plates are located inside the damping box.

[0015] The damping box is provided with isolation liquid. When the damping plates move relative to each other under the action of the isolation liquid in the damping box, the shaking speed and amplitude of the support rod can be reduced through the blocking of the isolation liquid, and thus the vibration of the casing can be buffered.

[0016] Preferably, the oil injection mechanism further includes a piston plate. The piston plate is fixedly installed at the top end of the support rod. The piston plate is slidably installed on the inner wall of the oil injection box, and the piston plate is in mutual fit with the inner wall of the oil injection box.

[0017] The piston plate is in mutual fit with the inner wall of the oil injection box, so as to be able to push the oil liquid in the oil injection box and inject it above the partition through the through hole, thus facilitating the oil injection through the oil injection pipe.

[0018] Preferably, an opening is formed on one side of the throttle barrel. A mounting rod is fixedly installed on the inner wall of the throttle barrel. A top rod is slidably connected to the mounting rod. One end of the top rod is fixedly installed with a throttle ball. The throttle ball is in mutual fit with the opening. A top spring is fixedly installed on one side of the mounting rod, and one end of the top spring is fixedly connected to the throttle ball.

[0019] The opening provided on the throttle barrel facilitates the pumping in of the external oil liquid. At the same time, the setting of the top rod and the top spring on the mounting rod facilitates the closing of the opening to prevent the oil liquid in the throttle barrel from being discharged. When suction occurs in the throttle barrel, the throttle ball is driven to retract inward, and then the opening is opened to facilitate the entry of the oil liquid. The top rod is slidably connected to the mounting rod, so as to be able to directionally limit the throttle ball.

[0020] Preferably, a fixing rod is fixedly installed on the inner wall of the oil injection box. A pull spring is fixedly installed on the fixing rod. The top end of the pull spring is fixedly installed with a plug ball. A throttle ring is fixedly installed on the inner wall of the oil injection box, and the throttle ring is in mutual fit with the plug ball.

[0021] The tension spring is arranged on the fixed rod. Under the action of the throttle ring, when the piston plate pushes upward, the oil in the oil injection box pushes the plug ball away from the throttle ring, causing the throttle ring to open and facilitating the discharge of the oil. When the piston plate sucks downward, the tension spring retracts and pulls the plug ball to close the throttle ring, preventing the oil above the partition from flowing back into the oil injection box, thus enabling the oil in the oil injection box to be exported unidirectionally.

[0022] Preferably, a blower is fixedly installed on the outer side of the machine shell. Conduits are installed at both the top and bottom of the blower. Exhaust boxes are fixedly installed at both the top and bottom of the machine shell. Air outlet holes are formed in the exhaust boxes, and the conduits are fixedly connected to the corresponding exhaust boxes.

[0023] Through the arrangement of the blower, it is convenient to blow air into the exhaust box through the conduit, and the air acts on the heat sink through the air outlet hole, thereby quickly dissipating heat from the heat sink.

[0024] Preferably, a transmission gear is fixedly installed on the spiral rotor, and the two transmission gears mesh with each other.

[0025] The output shaft of the motor can drive the spiral rotor to rotate in the reverse direction through the meshing of the two transmission gears, and then can suck in outside air through the intake pipe and discharge it through the exhaust pipe.

[0026] In summary, the technical effects and advantages of the present invention are as follows:

[0027] Through the arrangement of the oil cavity on the machine shell, it is convenient to isolate and reduce the noise inside the machine shell. At the same time, the heat sink is arranged in the oil cavity and is quickly cooled under the action of the blower, thus facilitating the rapid cooling of the inside of the machine shell.

[0028] There is isolation liquid in the damping box. When the damping plate moves relative to each other, the damping plate can reduce the shaking speed and amplitude of the support rod through the blocking of the isolation liquid, and thus buffer the vibration of the machine shell.

[0029] Through the mutual fitting of the piston plate and the inner wall of the oil injection box, the oil in the oil injection box can be pushed, and injected into the upper part of the partition through the through hole, thus facilitating oil injection through the oil injection pipe, and facilitating oil injection cooling and lubrication of the inside of the machine shell through the oil, while also increasing the sealing effect.

[0044] An air inlet pipe 15 is fixedly installed on the top of the casing 1, an exhaust pipe 16 is installed on the top of the casing 1, and a plurality of heat sinks 10 are installed on both the top and the bottom of the casing 1, and the heat sinks 10 extend into the oil chamber.

[0045] Refer to Figure 1 and Figure 6 Figure, the support and shock absorption mechanism 5 further includes a buffer spring 55, the buffer spring 55 is fixedly installed on the top of the cushion plate 54, a damping box 51 is fixedly installed on the top of the cushion plate 54, the damping box 51 is fixedly connected to the bottom of the casing 1, the support rod 52 is slidably connected to the damping box 51, and three damping plates 53 are fixedly installed on the support rod 52, the damping plates 53 are located inside the damping box 51. The buffer spring 55 and the cushion plate 54 buffer and reset between the damping box 51 and the support rod 52, and at the same time support the support rod 52. There is isolation liquid in the damping box 51. Under the action of the isolation liquid in the damping box 51, when the damping plates 53 move relative to each other, through the blocking of the isolation liquid, the shaking speed and amplitude of the support rod 52 can be reduced, and thus the vibration of the casing 1 can be buffered.

[0046] Refer to Figure 6, the oil injection mechanism 6 further includes a piston plate 62. The piston plate 62 is fixedly installed at the top end of the support rod 52. The piston plate 62 is slidably installed on the inner wall of the oil injection box 61, and the piston plate 62 is in mutual fit with the inner wall of the oil injection box 61. An opening is formed on one side of the throttle cylinder 64. An installation rod 651 is fixedly installed on the inner wall of the throttle cylinder 64. A push rod 652 is slidably connected to the installation rod 651. One end of the push rod 652 is fixedly installed with a throttle ball 653. The throttle ball 653 cooperates with the opening. And a top spring 654 is fixedly installed on one side of the installation rod 651. One end of the top spring 654 is fixedly connected to the throttle ball 653. Through the mutual fit of the piston plate 62 with the inner wall of the oil injection box 61, the oil in the oil injection box 61 can be pushed, and can be injected above the partition plate 7 through the through hole, so as to facilitate the oil injection through the oil injection pipe 8. The opening provided on the throttle cylinder 64 facilitates the suction of the external oil. At the same time, the push rod 652 and the top spring 654 on the installation rod 651 are provided to facilitate the closing of the opening to prevent the oil in the throttle cylinder 64 from being discharged. When suction occurs in the throttle cylinder 64, the throttle ball 653 is driven to retract inward, and then the opening is opened to facilitate the entry of oil. The push rod 652 is slidably connected to the installation rod 651, so as to be able to perform directional limitation on the throttle ball 653.

[0047] Refer to Figure 6 , a fixing rod 661 is fixedly installed on the inner wall of the oil injection box 61. A tension spring 663 is fixedly installed on the fixing rod 661. The top end of the tension spring 663 is fixedly installed with a plug ball 664. A throttle ring 662 is fixedly installed on the inner wall of the oil injection box 61. The throttle ring 662 cooperates with the plug ball 664. The setting of the tension spring 663 on the fixing rod 661 and under the action of the throttle ring 662, when the piston plate 62 pushes upward, the oil in the oil injection box 61 pushes the plug ball 664 away from the throttle ring 662, so that the throttle ring 662 is opened and the oil is discharged conveniently. When the piston plate 62 sucks downward, when the tension spring 663 retracts, it pulls the plug ball 664 to close the throttle ring 662, preventing the oil above the partition plate 7 from flowing back into the oil injection box 61, so that the oil in the oil injection box 61 forms a one-way export.

[0048] Refer to Figure 2 , a blower 12 is fixedly installed on the outside of the machine case 1. Conduits 13 are installed at the top and bottom of the blower 12. Exhaust boxes 11 are fixedly installed at the top and bottom of the machine case 1. Air outlet holes 14 are formed in the exhaust boxes 11. The conduits 13 are fixedly connected to the corresponding exhaust boxes 11. Through the setting of the blower 12, it is convenient to blow air into the exhaust boxes 11 through the conduits 13, and act on the heat sink 10 through the air outlet holes 14, so as to quickly dissipate heat from the heat sink 10.

[0049] Refer to Figure 4, a transmission gear 9 is fixedly installed on the spiral rotor 3, and the two transmission gears 9 are meshed with each other. The output shaft of the motor 2 can drive the spiral rotor 3 to rotate in the reverse direction through the meshing of the two transmission gears 9, and then can suck the outside air through the intake pipe 15 and discharge it through the exhaust pipe 16.

[0050] Working principle: During operation, the output shaft of the motor 2 can drive the spiral rotor 3 to rotate in the reverse direction through the meshing of the two transmission gears 9, and then can suck the outside air through the intake pipe 15 and discharge it through the exhaust pipe 16. When the machine shell 1 vibrates, the buffer spring 55 and the cushion plate 54 buffer and reset the damping box 51 and the support rod 52, and at the same time support the support rod 52. There is isolation liquid in the damping box 51. Under the action of the isolation liquid in the damping box 51, when moving relative to each other, the shaking speed and amplitude of the support rod 52 can be reduced through the blockage of the isolation liquid, and then the vibration of the machine shell 1 can be buffered. When the support rod 52 moves up and down, the support rod 52 drives the piston plate 62 to move. The piston plate 62 can push the oil liquid in the oil injection box 61 through the mutual fit with the inner wall of the oil injection box 61 and inject it above the partition plate 7 through the through hole, so as to facilitate the oil injection through the oil injection pipe 8. The opening of the throttling cylinder 64 is arranged to facilitate sucking the outside oil liquid. At the same time, the arrangement of the ejector rod 652 and the ejector spring 654 on the mounting rod 651 can facilitate closing the opening to prevent the oil liquid in the throttling cylinder 64 from being discharged. When suction occurs in the throttling cylinder 64, the throttling ball 653 is driven to retract inward, and then the opening is opened to facilitate the entry of oil liquid. The ejector rod 652 is slidably connected to the mounting rod 651, so as to positionally limit the throttling ball 653. The arrangement of the tension spring 663 on the fixed rod 661 and under the action of the throttling ring 662, when the piston plate 62 pushes upward, the oil liquid in the oil injection box 61 pushes the plug ball 664 away from the throttling ring 662, so that the throttling ring 662 is opened and the oil liquid is discharged conveniently. When the piston plate 62 sucks downward, the tension spring 663 retracts to pull the plug ball 664 to close the throttling ring 662 to prevent the oil liquid above the partition plate 7 from flowing back into the oil injection box 61, so that the oil liquid in the oil injection box 61 forms a one-way export. Through the arrangement of the blower 12, it is convenient to blow the exhaust air box 11 through the conduit 13 and act on the heat sink 10 through the air outlet hole 14, so as to quickly dissipate the heat of the heat sink 10, and then cool down the inside of the machine shell 1 through the oil cavity.

[0051] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
