Valve reed, compressor, and vehicle

A compressor, comprising:

• a cylinder having a compression chamber, wherein the compression chamber has an intake hole and a discharge hole;
• a piston assembly comprising a piston and a piston frame, wherein the piston is arranged at least one end of the piston frame and configured to compress gas in the compression chamber;
• a driving device connected to the piston frame to drive the piston to move within the cylinder;
• and
• a valve reed arranged on the cylinder,
• wherein the valve reed comprises a plate body, the plate body defines a slit extending through the plate body along a thickness direction of the plate body, and the slit divides the plate body into a central sealing portion, a mounting portion, a peripheral sealing portion, a plurality of first swing arms, and a plurality of second swing arms;
• wherein the central sealing portion, the mounting portion, and the peripheral sealing portion are concentric with each other, the mounting portion surrounds the central sealing portion, and the peripheral sealing portion surrounds the mounting portion,
• wherein the plurality of first swing arms are located between the peripheral sealing portion and the mounting portion, a first end of each first swing arm is connected to the peripheral sealing portion, and a second end of each first swing arm is connected to the mounting portion,
• wherein the plurality of second swing arms are located between the central sealing portion and the mounting portion, a first end of each second swing arm is connected to the central sealing portion, and a second end of each second swing arm is connected to the mounting portion, and
• wherein one of the central sealing portion and the peripheral sealing portion is configured to open and close the intake hole, and the other of the central sealing portion and the peripheral sealing portion is configured to open and close the discharge hole.

A vehicle, comprising:

• a pneumatic device;
• and
• a compressor, comprising:

• a valve reed arranged on the cylinder,
• wherein the valve reed comprises a plate body, the plate body defines a slit extending through the plate body along a thickness direction of the plate body, and the slit divides the plate body into a central sealing portion, a mounting portion, a peripheral sealing portion, a plurality of first swing arms, and a plurality of second swing arms;
• the central sealing portion, the mounting portion, and the peripheral sealing portion are concentric with each other, the mounting portion surrounds the central sealing portion, and the peripheral sealing portion surrounds the mounting portion;
• the plurality of first swing arms are located between the peripheral sealing portion and the mounting portion, a first end of each first swing arm is connected to the peripheral sealing portion, and a second end of each first swing arm is connected to the mounting portion;
• the plurality of second swing arms are located between the central sealing portion and the mounting portion, a first end of each second swing arm is connected to the central sealing portion, and a second end of each second swing arm is connected to the mounting portion;
• and
• one of the central sealing portion and the peripheral sealing portion is configured to open and close the intake hole, and the other of the central sealing portion and the peripheral sealing portion is configured to open and close the discharge hole;
• and
• wherein the compressor is connected to the pneumatic device to supply compressed gas to the pneumatic device.
