Desktop Sterilizer Air Control Door Lock

Abstract

The invention discloses a desktop sterilizer air control door lock, which comprises a door lock mechanism and an air control mechanism that coordinate mutually. The door lock mechanism is provided with a pivot, a male lock catch, a female lock catch, and a retaining piece, and can realize opening and closing of a sterilizing chamber door. The air control mechanism is provided with a cavity communicated with the interior of the sterilizing chamber and a piston rod, and the piston rod cooperates with the retaining piece so as to realize control of the open and close of the sterilizing chamber door. For the desktop sterilizer air control door lock provided in the invention, when positive pressure exists in the sterilizing chamber, the piston rod stretches out of an air tank so as to stop rotation of the pivot, thereby preventing the sterilizing chamber door from being opened under a normal working state. When the pressure in the sterilizing chamber is zero or a negative value, the piston rod retracts into the air tank, then the pivot can rotate unimpededly, and further the sterilizing chamber door can be opened, thus ensuring the use safety of the desktop sterilizer.

Description

technical field [0001] The invention relates to a door lock control mechanism of a desktop sterilizer, in particular to an air-controlled door lock of a desktop sterilizer. Background technique [0002] The desktop pressure steam sterilizer injects steam into the closed sterilization chamber by a steam generator to generate a certain temperature and pressure, and then conduct various operation experiments in this closed space. When the sterilizer is working normally, if the door of the sterilization chamber is opened due to the operator's mistake, the high-temperature and high-pressure gas inside may cause danger to the surrounding personnel. In order to prevent the operator from opening the door by mistake even when the sterilizer is under pressure, some manufacturers adopt the principle of electric control bolt, and when the sterilizer starts to work, the door handle is tied so that the operator cannot open the door, that is, When there is air pressure in the sterilizatio...

AI Technical Summary

Problems solved by technology

In order to prevent the operator from opening the door by mistake even when the sterilizer is under pressure, some manufacturers adopt the principle of electric control bolt, and when the sterilizer starts to work, the door handle is tied so that the operator cannot open the door, that is, When there is air pressure in the sterilization chamber, the door of the sterilization chamber is locked and cannot be opened

[0003] However, in the process of use, it was found that there was a defect in this prior art, that is, when there was a sudden power failure during use, the door would not be able to be opened. cause great trouble to users
