After the sample injection bottle 7 is washed, the controller 62 switches the inlet channel corresponding to the heat preservation gas storage bottle 56 to be communicated with the infusion pump 41, hot air in the heat preservation gas storage bottle 56 is pumped into the infusion pump 41 through the multi-channel switching valve 63, the infusion pump 41 is a gas-liquid dual-purpose pump, the hot air enters the flushing pipe 32 through the infusion pump 41, the flushing pipe 32 blows out the hot air to blow dry the inside of the sample injection bottle 7, the cleaning program of the sample injection bottle 7 is completed, and the controller 62 closes the air pump 52. At this time, the buzzer 9 emits an end prompt sound to prompt the operator to take off the sample bottle 7 and put in the next sample bottle 7 to be cleaned.

The air pump 52 pumps new air into the heat preservation air storage bottle 56, the heating module 51 heats the air in the bottle, sufficient air pressure is supplemented into the heat preservation air storage bottle 56, when the air pressure in the bottle is higher than an air pressure safety value, the pressure release valve 57 is opened, and redundant air pumped into the air pump 52 is discharged from the pressure release valve 57. When the temperature of the gas in the bottle reaches the working temperature, the heating module 51 is in a heat-preserving state. The control panel 112 displays parameters of various steps in the cleaning process, such as: the flow rate of the cleaning liquid, the time, the temperature of the hot air, the air pressure and the blowing time, and the operator can adjust and set the parameters of each step through the control panel 112.

The above description is only for the embodiments of the present invention, and it is obvious to those skilled in the art that various changes and modifications can be made without departing from the inventive concept of the present invention, and these changes and modifications are all within the scope of the present invention.
