It should be noted that the following embodiments are only used to explain the present application and do not constitute a limitation on the present application.

[0028] Embodiment 1:

[0029] like Figure 1-3 A transfer window for transferring articles between different clean areas of a clean room comprises: a frame 1, a blowing unit, and a return air unit. The lower part of the frame 1 is a transfer area, and the upper part of the frame 1 is an installation area. The blowing unit is arranged in the installation area, and is used to blow air with a preset wind speed to the transfer area. The wind speed of the air blown by the blowing unit to the transfer area is 18-20m / s. The return air unit is arranged in the transfer area, and is used to guide the air in the transfer area to the installation area.

[0030] A partition plate is installed in the middle of the frame 1, and the partition plate divides the interior of the frame 1 into two independent transfer areas and installation areas. The front and rear sides of the installation area are respectively installed with a main object door 5 and a secondary object door 4. The main object door 5 and the secondary object door 4 are both made of stainless steel, and two transparent tempered glasses are installed on them to facilitate observation of the status of the objects in the transfer area.

[0031] In this embodiment, the blowing unit includes: a fan 6, a high-efficiency filter 7, and an air shower nozzle 8. The fan 6 is used to transfer air to the air shower nozzle 8 through the high-efficiency filter 7. The air shower nozzle 8 is arranged on the partition plate, and air with a preset wind speed is blown to the transfer area through the air shower nozzle 8.

[0032] In this embodiment, the return air unit includes: a return air orifice plate 10, the return air orifice plate 10 is arranged on both sides of the transfer area, and the return air orifice plate 10 and the two side walls of the transfer area form a closed return air cavity, the top of the return air cavity is connected to the installation area, and a plurality of return air holes are arranged on the return air orifice plate 10. A purple light 9 is arranged on the return air orifice plate 10 on the side away from the return air cavity.

[0033] When it is necessary to transfer items, the electromagnetic lock is disconnected by controlling the operation panel 3, and the main item door 5 and the auxiliary item door 4 can be opened. After opening the main item door 5 to send the items into the transfer area, the main item door 5 is closed, and the controller starts the fan 6. The air first passes through the high-efficiency filter 7, and then is sprayed into the cabin at high speed through the air shower nozzle 8 to remove dust from the surface of the items. The dust-carrying air enters the return air chamber through the return air hole on the return air orifice plate 10, and is blown into the installation area through the fan 6 to complete the cycle. At the same time, during the shower process, the ultraviolet lamp 9 is turned on to emit ultraviolet rays to sterilize the surface of the items. A pressure differential gauge 2 is provided on the outside of the installation area. By observing the 500Pa pressure differential gauge 2 on the front, the high-efficiency filter 7 needs to be replaced when the specified value is reached.

[0034] The present invention is made of SUS304 stainless steel as a whole, and the inner edge of the transfer area adopts arc transition, which has many advantages such as corrosion resistance, easy cleaning, and no dust accumulation.

[0035] The cleaning and sterilization time can be set by yourself, and the auxiliary material door 4 can be opened to take out the items after the cleaning and sterilization are completed. The fan 6 is set with five speed adjustment gears, and the fan 6 is adjusted by the controller to reach the required wind speed.

[0036] The above description is only a preferred embodiment of the present invention and is used to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
