DETAILED DESCRIPTION

[0029] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0030] Embodiment 1:

[0031] A cylinder head structure includes a crankcase 1, a motor 2, a transmission assembly 3 and a compression assembly 4, wherein the motor 2 and the transmission assembly 3 are arranged in the crankcase 1, and the transmission assembly 3 is arranged at the output end of the motor 2. A cooling assembly 5 is also included. A compression box 1 6 and a compression box 2 7 are arranged at the upper end of the crankcase 1. The compression assembly 4 includes a first compression air duct 8, a second compression air duct 9 and a piston member 10. An air intake port 1 11 and an air outlet 1 12 are respectively arranged at both ends of the first compression air duct 8, an air intake port 2 13 and an air outlet 2 14 are respectively arranged at both ends of the second compression air duct 9. The piston member 10 is arranged at the output end of the transmission assembly 3, and drives the first compression air duct 8 and the second compression air duct 9 to inhale and compress air. A pressure cover 15 is also arranged at the upper end of the compression assembly 4, and the pressure cover 15 is used to close the air outlet 12 and connect the first compression air duct 8 with the second compression air duct 9.

[0032] A compression chamber 16 and a compression chamber 2 17 are provided in the compression box 1 6, a compression chamber 3 18 and a compression chamber 4 19 are provided in the compression box 2 7, a connecting pipe 1 20 is provided between the compression chamber 1 16 and the compression chamber 3 18, a connecting pipe 21 is provided between the compression chamber 2 17 and the compression chamber 4 19, and a check valve 3 22 is provided in the connecting pipe 1 20 and the connecting pipe 2 21 to prevent gas backflow, the air inlet 1 11 and the air outlet 1 12 are respectively provided at the side ends of the compression chamber 1 16 and the compression chamber 3 18, the air outlet 2 14 and the air inlet 2 13 are respectively provided at the side ends of the compression chamber 2 17 and the compression chamber 4 19, the compression chamber 1 16, the compression chamber 3 18 and the connecting pipe 1 20 The combination forms a first compressed air passage 8, and the compression chamber 2 17, the compression chamber 4 19 and the connecting pipe 2 21 form a second compressed air passage 9. When it is necessary to compress the gas, the transmission component 3 drives the first compressed air passage 8 and the second compressed air passage 9 to alternately compress the gas, thereby reducing the high-pressure gas pulses generated by intermittent movement. By setting a pressure cover 15 and closing the gas outlet 12 while connecting the first compressed air passage 8 with the second compressed air passage 9, the first compressed air passage 8 and the second compressed air passage 9 are connected after the pressure cover 15 is installed, and the gas outlet 12 is closed, so that when the gas enters the second compressed air passage 9 from the first compressed air passage 8, secondary compression is formed.

[0033] When efficient and smooth compression efficiency is required, there is no need to install the gland 15, and a relatively smooth low-pulse air supply can be achieved by connecting the air outlet 12 and the air outlet 2 14 in parallel. When higher-pressure gas is required, it can be achieved by installing the gland 15. The cylinder head output mode can be switched by installing or removing the gland 15 to adapt to more types of equipment. At the same time, the gland 15 is installed on the compression component 4 to prevent the heat generated by the secondary compressed gas from being transferred to the compression component 4 and causing burns to the operator, thereby playing a heat-insulating and scalding prevention role.

[0034] A pressure hole 23 is also provided between the compression chamber 3 18 and the compression chamber 4 19, and a booster 24 is provided in the pressure hole 23. The booster 24 includes a pressure rod 25, a pressure block 26, a pressure ring 27 and a spring 28. An inclined pressure hole 29 is provided in the pressure rod 25, and an inclined top surface 30 matching the inclined pressure hole 29 is provided on one side of the pressure block 26. The spring 28 is provided on the other side of the pressure block 26 and abuts against the pressure ring 27. A pressure flow channel 31 is provided in the pressure block 26, and a pressure flow channel 31 is provided in the middle of the pressure ring 27. A plug 70 is also provided, which extends into the pressure channel 1 31. A pressure channel 2 32 is also provided on the pressure ring 27. When the pressure cover 15 blocks the gas outlet 12, the gas pressure in the compression chamber 3 18 will rise. When the transmission assembly 3 drives the piston 10 to move and the air pressure rises to a certain value, the air pressure pushes the pressure block 26 to move and compresses the spring 1 28. When the pressure block 26 is separated from the plug 70, the gas can enter the compression chamber 4 19, thereby realizing two-stage compression.

[0035] The compression box 27 is vertically provided with an indication hole 33, the pressure rod 25 is arranged in the indication hole 33, a tripod 34 is also arranged in the pressure hole 23, a top 35 is arranged in the middle of the tripod 34, a slide groove 36 cooperating with the top 35 is arranged on the end surface of the plug 70, a top 37 is arranged in the oblique pressure hole 29, a slide groove 38 cooperating with the top 37 is arranged on the end surface of the pressure block 26, and a micro switch 39 is also arranged on the upper end of the compression box 27, and the pressure rod 25 touches the micro switch when it moves upward. Switch 39, a spring 240 is also provided at the lower end of the pressure rod 25. In the first-stage compression mode, the pressure in the compression chamber 3 18 can be detected by the booster 24. When the pressure is too high, the pressure block 26 will still be pushed to move. When the pressure is too high, the pressure block 26 continues to move, so that the top head 37 is separated from the slide groove 38. At this time, the spring 240 exerts force to drive the pressure rod 25 to move upward, and the pressure rod 25 triggers the micro switch 39, thereby stopping the cylinder head from running, which plays a role in overload protection.

[0036] A booster 24 is also provided in the compression box 1 6. The difference from the compression box 2 7 is that the booster 24 in the compression box 1 6 does not have a plug 70, a pressure channel 1 31 and a pressure channel 2 32. The booster 24 in the compression box only needs to monitor the pressure in the compression chamber 2 17 in the first-stage compression mode.

[0037] The pressure ring 27 includes a mounting seat 41, an outer ring 42 and an inner top 43. The mounting seat 41 is fixed to the outside of the pressure hole 23 by screws, the outer ring 42 is threadedly matched with the mounting seat 41, and the inner top 43 is threadedly matched with the outer ring 42. When it is necessary to adjust the limit air pressure in the compression chamber three 18 under the secondary compression state, the outer ring 42 can be selected when adjusting the tightness of the spring one 28. When it is necessary to adjust the overload air pressure in the compression chamber three 18 under the primary state, the inner top 43 can be adjusted to change the distance between the top head and the slide groove two 38.

[0038] The top of the compression box 16 and the compression box 27 are both provided with a pressure cover 15, and the two pressure covers 15 are slightly different. The pressure cover 15 on the top of the compression box 27 can seal the air outlet 12 and the air inlet 2 13, and the compression box 16 does not need to seal the air outlet 2 14 and the air inlet 11. A mesh is provided on the top surface of the pressure cover 15 to facilitate the heat dissipation of the compression box 16 and the compression box 27. A card joint 44, a sealing gasket 45 and a pressure head 46 are provided on the inner side of the pressure cover 15. Only the compression box 27 is provided with a sealing gasket 45, which is provided at the air outlet 12 and the air inlet At 13, the sealing is increased, and the pressure head 46 is set at the upper end of the pressure rod 25. When the pressure head 46 is not set, the pressure rod 25 is easy to rise during the secondary compression, resulting in uneven force on the pressure block 26, and it is difficult to push the spring 28. The outer ends of the compression box 1 6 and the compression box 2 7 are provided with a snap-in groove, and the snap-in joint 44 cooperates with the snap-in groove to fix the pressure cover 15, and the pressure rod 25 is pressed by the pressure head 46, so that in the secondary compression state, the pressure rod 25 cannot be pushed out, thereby preventing the micro switch 39 from being triggered, and at the same time making the pressure block 26 evenly stressed.

In the first-stage compression mode, when the pressure is greater than the adjusting spring 1 28, the pressure relief channel 71 is opened. Start, a certain degree of pressure relief can be carried out through the pressure relief channel 71 to prevent the compression efficiency from being too high, the gas consumption of the gas-consuming equipment cannot keep up with the compression amount, resulting in the gradual triggering of the micro switch 39 to cause shutdown. In the secondary compression mode, the pressure head 46 is pressed against the outlet of the pressure relief channel 71 and the lock cover channel 72 is connected to the pressure relief channel 71, so that under high pressure, the lock cover top 73 is stuck in the groove 75, and the pressure cover 15 is locked to prevent the pressure cover 15 from detaching due to excessive pressure.

[0040] The transmission assembly 3 is symmetrically arranged on both sides of the motor 2, including a center rod 47, a driving crankshaft 48, a balancing rocker 49, a swing sleeve 50 and a fan blade 51.

A partition plate 54 is arranged in the piston sliding chamber 53, and a partition groove 55 cooperating with the partition plate 54 is arranged in the middle of the piston head 52.
