Moreover, it is inconvenient to control the temperature of the air and adjust the discharge temperature of the air. Summary of the Utility Model

[0007] Further, an air inlet is opened in the middle of the front end of the outer plate shell; an oxygen outlet is opened in the middle of the rear end of the outer plate shell.

[0008] Further, a connection groove is opened at the front end of one side of the outer plate shell; a circulating water path is arranged inside the cooler, and a pipeline is arranged outside the cooler and connected to a connection joint inside the connection groove.

[0009] Further, a transmission frame is fixedly arranged at the front side inside the outer plate shell, a driving motor is fixedly arranged outside the transmission frame, a transmission screw is fixedly arranged at the shaft end of the driving motor, and the driving motor is in threaded connection with the sliding plate A.

[0010] Further, partition plates arranged in a staggered manner are integrally arranged in the middle of the oxygen channels; through slots are opened at the front and rear ends of the adjacent surfaces of the two oxygen channels, and particle - blocking filter plates are fixedly inserted into the through slots.

[0011] Furthermore, a sliding rod is slidably arranged inside the middle frame. A spring is sleeved on the front end of the sliding rod, and a flow blocking block is fixedly arranged. A trapezoidal plate is fixedly arranged at the rear end of the sliding rod, and the trapezoidal plate fits with the oxygen outlet.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] An oxygen channel is provided, which provides a stable flow splitting function. A partition is arranged inside the oxygen channel to equalize the internal flow direction of the oxygen channel and can extend the flow distance. Air passes through the front-side particle-blocking filter plate and enters the oxygen channel, then passes through the rear-side particle-blocking filter plate, and is discharged to the oxygen supply position through the side slits of the trapezoidal plate. In addition, when the air supply stops, both the flow blocking block and the trapezoidal plate are automatically reset by the spring force to close the oxygen channel and achieve a sealing effect.

[0014] A heater is provided to heat the temperature. When the temperature needs to be adjusted, air passes through the heater and is heated and then transported backward, heating the air to an appropriate temperature during the air supply process. The heater can be adjusted by monitoring the temperature at the oxygen outlet.

[0015] A cooler is provided to reduce the air temperature. The connection joint is connected to the circulating pump and the water source to form a circulating water path. Then, the driving motor is started to drive the transmission screw to rotate. The transmission screw generates a threaded drive to drive the sliding plate A to move, aligning the cooler with the oxygen outlet. At this time, the temperature of the air can be reduced by using the principle of water-cooled heat exchange, and then the temperature of the oxygen can be reduced for low-temperature oxygen supply.

[0031] As Figures 1-5As shown in the figure, air is input into the outer plate housing 1 through the air inlet 102. After the pressure increases, it pushes the flow-blocking block 7 backward. Then, the flow-blocking block 7 moves backward to expose a gap. At the same time, the trapezoidal plate 8 also extends backward.

When the air supply stops, both the flow-blocking block 7 and the trapezoidal plate 8 automatically reset through the spring force to seal the oxygen channel 2, achieving a sealing effect.
