Description

Technical fields:

[0001] This utility model relates to the technical field of compressors, and more specifically to a 360-degree annular magnetic control compressor. Background technology:

[0002] An air compressor is a device used to compress gas. Air compressors are similar in construction to water pumps. Most air compressors are reciprocating piston, rotary vane, or rotary screw types. However, the efficiency of air compressors, whether reciprocating piston, rotary vane, or rotary screw, is not very high. Therefore, rotary air compressors have been proposed. Rotary compressors are positive displacement compressors that use the rotational movement of one or more components to change the volume inside the compression chamber. Specifically, the compressor has a ring-shaped compression chamber with a piston that can rotate within it. To achieve compression, a valve block is also installed inside the compression chamber. The valve block can isolate the compression chamber, and when the piston moves towards the valve block, it can compress the air inside the compression chamber, greatly improving compression efficiency. A challenge with this rotary compressor is how to ensure that the piston can quickly pass over the valve block during high-speed rotation without colliding with it. Utility model content:

[0026] Example: See Figures 1 to 7 As shown, the 360-degree annular magnetic control compressor includes a circular housing 1, a motor 2 fixedly connected to the middle of the housing 1, and an annular compression channel 11 formed on the outer ring of the housing 1. Several arc-shaped pistons 3 are provided in the compression channel 11. The pistons 3 are connected to the motor 2, and the motor 2 drives the pistons 3 to rotate in the compression channel 11 of the housing 1.

[0027] The top of the housing 1 is formed with an exhaust valve seat 12 connected to the compression ring channel 11. A valve block 4 that cuts off the compression ring channel 11 is inserted into the valve cavity of the exhaust valve seat 12. The lower part of the valve block 4 is set in the compression ring channel 11 of the housing 1 and has an inclined opening and closing surface.

When the piston 4 approaches the valve block 4, the piston 4 drives the valve block 4 to move upward, and the valve cavity of the outlet valve seat 12 and the inlet hole on the housing 1 are connected.

[0029] The housing 1 consists of two symmetrical sets of front housing a and rear housing b, which are fixed together by bolts; the pistons 3 are evenly distributed in a ring around the central axis of the motor 2; as shown in the figure.

[0031] The lower surface of the valve block 4 is formed with an arc shape and abuts against the inner wall of the inner ring side of the compression ring channel 11. A transition guide circle 41 is formed between the lower surface of the valve block 4 and the opening and closing surface. The presence of the transition guide circle 41 can prevent the piston 3 from colliding with the valve block 4 and facilitate the movement of the valve block 4 by magnetic force.

[0032] An air intake connector 14 communicating with the compression ring channel 11 is formed on the outer wall of the upper part of the housing 1. The air intake pipe 9 is fixed to the air intake connector 14 and is arranged on the same side of the housing 1 together with the one-way valve 8. Its structure is as follows: Figure 1 As shown; of course, the intake connector 14 can also be omitted, and its intake pipe 9 can be directly installed on the housing 1 at the compression ring 11, as shown. Figure 5 , 6 As shown.

[0033] like Figure 1 , 2As shown in Figure 3, the motor 2 is an external rotor motor, which is installed inside the housing 1. The external rotor motor includes a stator in the middle and a rotor on the outside. A circular connecting ring is formed on the rotor, and the piston 3 is fixed to the connecting ring. The housing 1 has a cavity formed in the middle that protrudes to both sides, and the external rotor motor is installed inside the cavity.

[0034] A power connector 10, which is electrically connected to the external rotor motor, is fixed to the outer side of the housing 1.

[0035] like Figure 5 , 6 As shown, the motor 2 is an internal rotor motor, which is fixed to the outside of the housing 1. A rotating disk 31 is provided inside the housing 1, and the piston 3 is fixed to the rotating disk 31. The shaft of the internal rotor motor is inserted and fixed in the middle of the rotating disk 31. The internal rotor motor is directly installed on the outside of the housing 1 by bolts, and the power socket 10 is directly set on the outer shell of the internal rotor motor.

[0036] like Figure 3 , 4 As shown, the cross-sections of the piston 3, the compression ring 11, and the valve block 4 are all rectangular. The valve cavity inside the outlet valve seat 12 is rectangular. The side walls of the valve block 4 abut against the inner side walls of the valve cavity. A vertical vent pipe 42 is formed in the middle of the upper end face of the valve block 4. A vent cavity 43 connected to the vent pipe 42 is formed inside the valve block 4. Several vent holes 44 connected to the vent cavity 43 are formed on the opening and closing surfaces of the valve block 4 on both sides of the fixed magnet 7.

[0037] like Figure 6 , 7 As shown, the cross-sections of the piston 3, the compression ring channel 11, and the valve block 4 are all circular. The air inlet 15 is located inside the compression ring channel 11. A guide slide plate 45 is formed on the side of the valve block 4 near the air inlet 15. The guide slide plate 45 abuts against the inner wall of the valve cavity inside the outlet valve seat 12. The compression spring 5 is inserted on the guide slide plate 45 of the valve block 4. The other side of the valve block 4 is provided with a slot that connects the compression ring channel 11 and the valve cavity of the outlet valve seat 12.

[0038] Whether the piston 3 adopts a circular structure or a rectangular structure, it can be equipped with an external rotor motor or an internal rotor motor.

[0039] Working principle: This structure is a ring magnetic control compressor. The ring magnetic control compressor has a ring-shaped compression channel 11. The compression channel 11 is equipped with a valve block 4 and a piston 3. The piston 3 can rotate and move at high speed in the compression channel 11 under the action of the motor 2.

[0040] As the piston 3 rotates, it can compress the air in the compression ring channel 11, and the compressed air is output through the outlet valve seat 12 and the one-way valve 8.

[0041] When piston 3 approaches valve block 4, the moving magnet 6 on valve block 4 and the fixed magnet 7 on valve block 4 repel each other, driving valve block 4 to move upward. The upward movement of valve block 4 connects the inlet and outlet ends, releasing the air pressure in the outlet valve seat 12, allowing valve block 4 to continue to move upward. As a result, piston 3 can pass through the original position of valve block 4 at high speed without colliding or wearing with valve block 4, thus achieving efficient operation of the compressor.

[0042] The embodiments described above are illustrative of the present invention and are not intended to limit the present invention. Any person skilled in the art can modify the embodiments without departing from the spirit and scope of the present invention; therefore, the scope of protection of the present invention should be as set forth in the claims.
