A gap is also provided between the second plate 601 and the first air outlet 501, so that there is space for the relative movement of the first air outlet 501 and the second plate 601, thereby avoiding frictional contact.

[0040] The specific working process of a self-cleaning transfer window maintaining positive pressure described in an embodiment of the utility model is described below:

[0041] Press the non-toxic area to open the door, the fan will automatically start, put the items in and the fan will continue to run, turn on the UV for sterilization and the fan will continue to run, after the UV sterilization is finished, the toxic door will be unlocked and the fan will continue to run, open the toxic area door to take things out and the fan will continue to run, close the toxic door, and the fan will stop running. During the entire transfer process, the fan of the positive pressure self-cleaning transfer window is kept in the running state.

[0042] The principle of controlling the pressure difference in this embodiment is that when the door of the toxic area is opened, the second plate 601, under the action of the push rod 602, closes the first air outlet 501 in the working area, takes air from the non-toxic area, and exhausts the air in the window to the toxic area, ensuring that the pressure difference inside the working area is greater than that in the toxic area.

[0043] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0044] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
