[0137] The gas channel is provided with a gas pressure sensor, which includes a gas pressure sensor 1 6053 and a gas pressure sensor 2 6054. The outer air inlet channel 6086 and the inner air inlet channel 6087 detect the air inlet pressure through the gas pressure sensor 1 6053. The gas outlet channel 6088 is provided with a gas pressure sensor 2 6054. The gas outlet channel 6088 is provided with a flow regulating valve 609 at the rear side of the gas pressure sensor 2 6054. The gas pressure sensor 1 and the gas pressure sensor 2 are connected to the controller respectively.

[0138] By setting up a flow control plate and opening a pressure regulating hole, a pressure difference can be formed between the air inlet channel and the air outlet channel. Gas pressure sensor 1 and gas pressure sensor 2 upload the detected pressure values ​​in the tube to the controller. The controller calculates the flow rate of carbon dioxide according to the pressure difference value. The controller matches the calculated flow value with the set flow value, and controls the flow rate of gas in the air outlet channel through the flow regulating valve to ensure the appropriate flow rate and flow stability of carbon dioxide entering the gas-liquid mixing control module, thereby forming a fully closed-loop regulation and control of the carbon dioxide gas flow rate.

[0139] The flow regulating valve 609 includes a sleeve 6022, a driving mechanism and a flow control column 6092. An opening is provided on the gas outlet channel 6088.

A flow control groove 60883 matching the shape of the flow control plug 60924 is provided on the flow block 60884. The shapes of the flow control plug 60924 and the flow control groove 60883 are both inverted cone shape or inverted cone shape.

The fluid in the front section of the tube flows through the fluid through hole 1 60881, the flow control groove 60883, and the fluid through hole 2 60882 in sequence before entering the rear section of the tube; the cooperation between the flow blocking block 60884 and the flow control column 6092 can accurately adjust the flow accuracy according to the position of the flow control column 6092 in the flow control groove 60883, and when the flow control plug 60924 is fully inserted into the flow control groove 60883, the fluid passage can be disconnected.

[0141] The driving mechanism adopts a motor 6091, which is connected to a controller. An internal threaded hole 60921 is axially provided at the upper end of the column 60926. An external thread is provided on the motor shaft of the motor 6091. The motor shaft of the motor 6091 extends into the internal threaded hole 60921 and is threadedly connected to the column 60926.

[0144] The outer diameter of the large diameter end of the flow control plug 60924 is smaller than the outer diameter of the lower surface of the column 60926, and a lower limit surface is formed between the large diameter end of the flow control plug 60924 and the lower surface of the column 60926.

[0146] When the flow control plug 60924 is fully inserted into the flow control groove 60883 , the lower limit surface abuts against the upper surface of the flow blocking block, thereby blocking the connection between the flow control groove 60883 and the second fluid through hole 60882 .

The flow control column 6092 slides along the left guide surface 60223 and the right guide surface 60224 on the inner wall of the upper sleeve 60221. The sliding direction of the flow control column is limited so that it can only move along the axial direction of the sleeve 6022 but cannot rotate circumferentially, thereby ensuring the accuracy of the flow control column in adjusting the flow.
