Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in FIG. 1, the transfer window of the present embodiment is used for transferring articles between a clean zone and a clean zone, and between an unclean zone and a clean zone. The delivery window comprises a box body 1 and a filtering system. Wherein, the box body 1 comprises a first containing cavity 11 for transferring articles and a second containing cavity 12 for installing the filtering system, and the second containing cavity 12 is connected to the top of the first containing cavity 11. The box body 1 is provided with a front transfer door 111 and a rear transfer door 112 corresponding to the first accommodating cavity 11, the box body 1 is further provided with a movable plate 121 corresponding to the second accommodating cavity 12, and the movable plate 121 is arranged in parallel with the front transfer door 111 and the rear transfer door 112. The inner wall of the second accommodating cavity 12 is provided with a supporting frame 122, the filtering system comprises a high-efficiency filter 21 mounted on the supporting frame 122 and a fan 22 located above the high-efficiency filter 21, the fan 22 is used for pumping external gas into the second accommodating cavity 12, and the high-efficiency filter 21 is used for filtering the gas sent by the fan 22. The support frame 122 is provided with a first window corresponding to the filter screen of the high efficiency filter 21, so that the gas purified by the high efficiency filter 21 enters the first accommodating chamber 11 through the first window.

By means of the structure, the transmission window described in this embodiment divides the box body 1 into the first containing cavity 11 for transmitting articles and the second containing cavity 12 for installing the filtering system, which are connected up and down, and the movable plate 121 is correspondingly arranged in the second containing cavity 12 and parallel to the front transmission door 111 and the rear transmission door 112, so that when a person needs to maintain the filtering system, the filtering system can be maintained in a standing state only by opening the movable plate 121 like opening the transmission door, and the person does not need to bend down to drill the upper half body into the first containing cavity 11, thereby greatly reducing the difficulty of operation and lightening the labor intensity of the person.

Specifically, as shown in fig. 1, the first accommodating cavity 11 is substantially a rectangular parallelepiped or a square, a circular corner 113 is disposed on an inner wall of the first accommodating cavity 11, and the circular corner 113 is specifically disposed at a joint of each side wall of the first accommodating cavity 11. With this arrangement, the interior of the first accommodating chamber 11 is not prone to dust deposition and is easy to clean.

Specifically, as shown in fig. 1, the filter system further includes a fan guard 23 disposed outside the fan 22. More specifically, the fan guard 23 has a cross-sectional dimension substantially the same as the cross-sectional dimension of the high efficiency filter 21, and the fan guard 23 covers the fan 22 and is attached to the high efficiency filter 21. In this way, the gas drawn by the fan 22 can be concentrated in a small space and rapidly enters the first accommodating cavity 11 through the high-efficiency filter 21, and the fan cover 23 can effectively prevent the gas which is not purified by the high-efficiency filter 21 from entering the first accommodating cavity 11 and the second accommodating cavity 12, so that the pollution of the accommodating cavities by the unclean gas is avoided.

Specifically, as shown in fig. 1, the side wall of the first accommodating cavity 11 is further provided with an air return opening 114 communicated with the blower 22, so that gas generated by cleaning the articles in the first accommodating cavity 11 can be discharged as soon as possible, and when a conveying door close to one side of the clean room is opened, the gas in the first accommodating cavity 11 enters the clean room, thereby increasing the risk of contamination of the clean room.

Specifically, as shown in fig. 1 and fig. 2, a second window 1211 for allowing the detection device to extend into the first accommodating cavity 11 and/or the second accommodating cavity 12 is further disposed on the movable plate 121. Further, the detection device comprises an airflow sensing device 3 for detecting the air volume of the fan 22 and a cleanliness detection device 4 for detecting the cleanliness of the high-efficiency filter 21. Furthermore, a first hole for the airflow sensing device 3 to penetrate through is formed in the fan guard 23, and a second hole for the cleanliness detection device to penetrate through is formed in the supporting frame 122. Adopt above-mentioned scheme, can be convenient for monitor fan 22's air flow and the first cleanliness factor that holds in the chamber 11 to ensure that fan 22's air flow and the first cleanliness factor that holds chamber 11 reach predetermined standard, ensure to get into first holding in the chamber 11 to the article can be cleaned fully, avoid the article with impurity to enter into the clean room.

The present invention has been explained by using specific embodiments, and the explanation of the above embodiments is only used to help understand the method and the core idea of the present invention; meanwhile, for the general technical personnel in the field, according to the idea of the present invention, there are changes in the specific implementation and application scope, to sum up, the content of the present specification should not be understood as the limitation of the present invention.
