That is, the sealing strip 30 is abutted against the cabinet 10 or the sealing door 20 under the pushing action of the compressed air, so that the leakage of the high-pressure gas in the sterilization equipment is avoided, and the safety performance of the sterilization equipment is improved.
Alternatively, the sealing strip 30 may be made of a flexible material such as rubber. The air pressure detecting member 15 may be a pressure sensor.
It is understood that the sealing auxiliary device 50 provided in the present embodiment is used in an autoclave apparatus, but is not limited thereto, and may also be applied to other sterilization apparatuses requiring sealing by the sealing strip 30, so as to improve safety and avoid secondary contamination of sterilized articles.
As shown in fig. 2, the seal assisting apparatus 50 provided in this embodiment includes an air supply mechanism 1, the air supply mechanism 1 includes an air supply pipeline 11, and a backup compressed air source 12, a first check valve 13, a normally open valve 14 and an air pressure detecting member 15 connected to the air supply pipeline 11, an air outlet 111 of the air supply pipeline 11 is capable of supplying air, an air inlet 112 is connected to a main compressed air source, the normally open valve 14, the first check valve 13 and the air pressure detecting member 15 are all located upstream of the backup compressed air source 12, the first check valve 13 is located between the backup compressed air source 12 and the air pressure detecting member 15, and the first check valve 13 allows compressed air to flow from the air inlet 112 of the air supply pipeline 11 to the air outlet 111, that is, does not allow compressed air to flow from the air inlet 112 of the air supply pipeline 11 to the air outlet 111.
When the sterilization equipment is suddenly powered off but the main compressed air source is not powered off, the normally open valve 14 is kept on, the air outlet end 111 normally exhausts air, and the sealing strip 30 can be effectively sealed. When main compressed air source breaks off suddenly, atmospheric pressure detection piece 15 detects the pressure reduction in the air supply line 11, normally open valve 14 closes, normally open valve 14 and first check valve 13 make the air supply line 11 disconnection between reserve compressed air source 12 and the main compressed air source, avoid reserve compressed air source 12 to reveal, reserve compressed air source 12 provides compressed air for air supply line 11 this moment, guarantee the leakproofness between cabinet body 10 and sealing door 20, guarantee sterilizing equipment's security, and avoid the secondary pollution of sterilized article.
