[0046] Working principle: First, the vacuum pump 3 on the top of the box body 1 draws the air in the chamber through the exhaust pipe 4, and the sensor 5 monitors the pressure change in real time. When a certain vacuum degree is reached, the sealing door 6 forms a sealed space with the chamber wall through the sealing strip 7. Then the control box 12 starts the heating pipe 11 at the bottom of the steam pool 10, and the saturated steam generated is evenly diffused to the box body 1 through the leakage hole 9 on the bottom plate 8. The cold air is pushed out through the exhaust pipe 4 during the upward movement of the steam. The system performs multiple cycles of vacuum and steam. Each time the steam is injected, the pressure in the chamber rises to a preset value and is maintained for a period of time. Then the vacuum pump 3 rapidly releases the pressure, and the cycle is repeated to ensure complete air replacement. After sterilization is completed, the heating pipe 11 switches to the heat preservation mode, and the vacuum pump 3 starts the drying program to realize the drying of the instruments by discharging the moisture and filling the filtered air. The handle 23 of the sealing door 6 is linked with the pressure interlocking device to ensure that the sealing door 6 cannot be opened when the pressure in the chamber has not returned to normal.

The liquid level monitoring of the steam pool 10 and the overload protection of the control box 12 jointly guarantee the operation safety.

[0047] And, when the box 1 injects high temperature steam, the steam contacts the surface of the side plate 201 and the condensation inclined plate 203 and the temperature is reduced to form condensed water, the flow guide groove 202 on the outer wall of the side plate 201 guides the condensed water to flow downward along a specific path to avoid the influence of disordered dripping on the sterilization effect, the condensation inclined plate 203 is installed at a certain angle to accelerate the condensed water to converge to the side plate 201, at this time, the inclined groove 204 on the left and right sides of the inner wall of the box 1 is connected with the bottom of the side plate 201 to guide the condensed water flowing on both sides to the front side of the sewage collecting groove 205, in the steam injection stage, the condensed water in the sewage collecting groove 205 is continuously discharged through the drainage system, in the drying stage, when the vacuum pump 3 extracts the moisture in the cavity, the flow guide path formed by the inclined groove 204 and the sewage collecting groove 205 further promotes the discharge of residual moisture, in the whole process, the combined structure of the condensation inclined plate 203 and the side plate 201 increases the steam contact area and improves the condensation efficiency, the directional design of the flow guide groove 202 ensures that the condensed water quickly separates from the sterilization area, and the layout of the inclined groove 204 and the sewage collecting groove 205 realizes the centralized collection and complete discharge of the condensed water.
