Gas injection module and active gas injection system

An active gas injection system, comprising:

• at least one gas injection module having a device body, wherein an inside of the device body has a delivering cavity and an annular gas flow generation cavity, one end of the device body has a gas input portion, and another end of the device body has a gas output portion;
• wherein a lateral side of the device body extends outward to form a gas guiding portion;
• the delivering cavity, the gas input portion and the gas output portion are in spatial communication with one another, and the delivering cavity, the annular gas flow generation cavity, and the gas guiding portion are in spatial communication with one another;
• at least one gas supply module connected to the gas guiding portion;
• and
• a control module connected to the at least one gas supply module, wherein the control module is configured to control the at least one gas supply module to supply a driving gas flow to the gas injection module in a continuous manner or an intermittent manner;
• wherein the gas input portion is configured for connecting a first external operating apparatus, and the gas output portion is configured for connecting a second external operating apparatus;
• and
• wherein the annular gas flow generation cavity has a side connecting portion and at least one nozzle portion, the side connecting portion is in spatial communication with the at least one nozzle portion, and the side connecting portion is connected to the gas guiding portion;
• wherein the at least one nozzle portion is connected to the delivering cavity and is configured to generate a pushing gas flow to the delivering cavity along a pre-determined path, a pre-determined angle is defined between the pre-determined path and a central axis of the device body, and the pre-determined angle is between 0 degrees and 89 degrees.
