[0033] Specifically, in the solution of this embodiment, the linkage component 5 includes a tongue-shaped scraper 51, a seal 52 and a linkage spring 53; a tongue-shaped scraper straight groove 123 is provided at one end of the rotor 12 located in the right chamber 22; the linkage spring 53 is arranged in a compressed state at the bottom of the tongue-shaped scraper straight groove 123; the seal 52 is arranged on the inner side wall of the annular cylinder 2; one end of the tongue-shaped scraper 51 abuts against the linkage spring 53, and the other end is clamped on the seal 52.

[0036] Specifically, in the solution of this embodiment, the conversion hole 7 is arranged on the right sealing cover 134; the air inlet hole 8 is arranged on the left sealing cover 132; the air inlet hole 8 is communicated with the air delivery channel 136 through the connecting air channel 81. It should be noted that the conversion hole 7 and the air inlet hole 8 are used to realize the function of the conversion air channel. Specifically, during the rotation of the rotor 12, every time it rotates 360°, the conversion hole 7 is communicated with the air supply hole 121 once. Similarly, during the follow-up process of the annular cylinder 2, every time it rotates 360°, the air inlet hole 8 is communicated with the connecting air channel 81 once, so as to realize the function of the conversion air channel.

[0037] Specifically, in the solution of this embodiment, the air delivery assembly 4 includes an air delivery nozzle 41 and a round key 42; a clamping portion is arranged on the outer side wall of the air delivery channel 136; the air delivery nozzle 41 is sleeved on the outer side wall of the air delivery channel 136; one end of the air delivery nozzle 41 is fixed to the clamping portion through the round key 42. It should be noted that the round key 42 is used to fix the air delivery nozzle 41 to prevent it from coming off; the air delivery nozzle 41 is used to output high-pressure gas and is airtight at the same time. At the same time, the air delivery nozzle 41 is an air delivery part that converts rotational motion into compressed gas output as a power source.

[0038] Specifically, in the solution of this embodiment, the tongue-shaped scraping piece 51 includes a connecting rod scraping piece rod body and a connecting rod scraping piece hinge head; a hinge head hole groove is arranged on the sealing member 52; the connecting rod scraping piece hinge head is arranged at one end of the connecting rod scraping piece rod body; the connecting rod scraping piece rod body is installed in the tongue-shaped scraping piece straight groove 123; the connecting rod scraping piece hinge head is installed in the hinge head hole groove.

The offset rotating shaft 11 is a hollow shaft that can conduct air.

[0040] Specifically, in the solution of this embodiment, the inner wall diameter of the annular cylinder 2 is greater than the sum of the outer wall diameter of the rotor 12 and the thickness of the sealing member 52. Thus, the annular cylinder 2 and the rotor 12 can be arranged coaxially and eccentrically. The annular cylinder 2 follows the rotation of the rotor 12 through the linkage assembly 5, converts the rotational motion of the rotor 12 into compressed gas output as a power source, and has stable, reliable and wide application.

[0041] Specifically, in the solution of this embodiment, both the left sealing cover 132 and the right sealing cover 134 are made of heat-treated wear-resistant materials.

[0042] The following uses several typical rotation angles to illustrate the air compression working principle of the present invention:

[0043] The gas compression principle of the utility model:

[0044] Intake process: Figures 1 to 3 As shown, the rotating shaft 11 drives the rotor 12 to rotate as a whole, and the annular cylinder 2 rotates with the rotor 12 in the linkage assembly 5. The gas enters the rotating shaft 11 from the air inlet 111, turns 90° at the conversion hole 7 and enters the air supply hole 121 to complete the air supply. The rotor 12 transmits torque through the tongue-shaped scraper 51 to make the annular cylinder 2 follow. Due to the mutual sealing effect of the closing band 6, the tongue-shaped scraper 51 and the sealing member 52, at this time, after the sealing member 52 rotates 360° clockwise relative to the closing band 6 (A), the volume of the left chamber 21 of the annular cylinder 2 changes from small to large, and the entire intake process is completed.

[0045] Gas compression process: When the seal 52 rotates 360° clockwise relative to the closing band 6 (A), the gas in the right chamber 22 of the annular cylinder 2 is continuously compressed. The compressed gas enters through the gas inlet 122 and can only move to the left (towards the direction of the gas delivery component 4) under the action of the one-way valve 9. After the compressed gas is turned to the gas delivery channel 136 at the connecting gas channel 81, the compressed gas is output to the outside through the gas delivery nozzle 41, completing the entire process of gas compression and delivery.

[0046] Every time the rotor 12 rotates 360°, it simultaneously takes in air once and compresses and discharges gas once.

[0047] Embodiment 2:

[0048] Reference Figure 12 On the basis of Example 1, the gas delivery nozzle 41 and the annular cylinder 2 are improved. A lubricating oil inlet hole 43 is provided on the side wall of the gas delivery nozzle 41, and lubricating oil can be injected through the lubricating oil inlet hole 43. The outer edge of the annular cylinder 2 is symmetrically provided with protrusions 23 on both sides, which can increase the width of the sealing bands on both sides, enhance the mechanical strength of the outer circle and the shape and position tolerance.
