[0014] 1. When replenishing salt water, the external salt water tank injects salt water into the inner cavity of the shell through a connecting pipe, and transports it to the inner cavity of the mixing chamber through the drainage pipe. When the salinity meter detects that the salt water concentration exceeds the threshold, the external fresh water tank injects fresh water into the inner cavity of the mixing chamber through another connecting pipe, and simultaneously turns on the motor to drive the stirring blade to work. The stirring blade drives the salt water and fresh water in the mixing chamber to mix. When the salt water concentration reaches the standard, the salt water can be discharged through the drainage pipe, which plays the role of being able to adjust the concentration of salt water, so that the test personnel can control the concentration of salt water and the test accuracy is convenient for the staff;

When the salty and fresh water are injected into the inner cavity of the shell through the connecting pipe, the water enters the inner cavity of the impact chamber through the connection with the control valve, and the bubbles in the water can be eliminated by the impact of the water flow through the curved design of the impact chamber. When the water continues to enter the inside of the impact chamber, the water flow drives the cutting blade to rotate through its own impact, eliminates the tiny bubbles in the water, and discharges the gas by connecting the exhaust pipe with the impact chamber, which makes it easy to eliminate the bubbles in the salty and fresh water, and avoids the situation where too many bubbles in the mixing chamber affect the detection accuracy of the salinity meter.

[0027] In this embodiment, the external salt water tank injects salt water into the inner cavity of the housing 22 through a connecting pipe 24, and transports it to the inner cavity of the mixing chamber 11 through the drain pipe 257. When the salinity meter 21 detects that the salt water concentration exceeds the threshold, the external fresh water tank injects fresh water into the inner cavity of the mixing chamber 11 through another connecting pipe 24, and simultaneously turns on the motor 26 to drive the stirring blade 27 to work. The stirring blade 27 drives the salt water and fresh water in the mixing chamber 11 to mix. When the salt water concentration reaches the standard, the salt water can be discharged through the drain pipe 28.

[0028] In this embodiment, a sealing ring is installed at the penetration point between the motor 26 and the refilling tank 10. The sealing ring is made of a rubber component; the penetration point between the motor 26 and the refilling tank 10 can be sealed to prevent salt water from leaking through the penetration point.

When the salinity meter 21 detects that the salt water concentration exceeds the threshold value, the external fresh water tank injects fresh water into the inner cavity of the mixing chamber 11 through another connecting pipe 24, and simultaneously turns on the motor 26 to drive the stirring blade 27 to work. The stirring blade 27 drives the salt water and fresh water in the mixing chamber 11 to mix. When the salt water concentration reaches the standard, the salt water can be discharged through the drainage pipe 28.
