AIR SHOWER CLEANING DEVICE WITH NON-DEFEATABLE FUNCTION

An air shower device with a non-defeatable function of removing contaminants from objects within a receiving space includes a room, a first barrier, a second barrier, and two revolving doors. The room defines the receiving space. The first barrier is disposed in the receiving space. The second barrier is disposed in the receiving space. The first barrier and the second barrier are misaligned with each other. The first barrier and the second barrier divide the receiving space into a plurality of channels connected to each other. The channels are arranged in a zigzag manner. The two revolving doors are installed at two ends of the channels.

The subject matter herein generally relates to sterilizing techniques, and more particularly, to an air shower device.

BACKGROUND

Air showers are installed at an entrance to a clean room for medical procedures, manufacturing semiconductors, precision electronics, and food. When objects (such as people or goods) enter the air shower, clean air is jetted out, which should remove dust particles attached to surface of the objects.

However, when the objects stay in the air shower only for a short time, the air shower may not completely remove the dust particles, and thus a sterile or cleaned atmosphere is lost. Therefore, there is a room for improvement.

FIG. 1illustrates an embodiment of an air shower device100. The air shower device100includes a room10, a first barrier20, a second barrier21, and two revolving doors40.

In an embodiment, the room10includes a first sidewall101, a second sidewall102, a third sidewall103, and a fourth sidewall104. The first sidewall101, the second sidewall102, the third sidewall103, and the fourth sidewall104are connected in that order. The first sidewall101is opposite to the third sidewall103, and the second sidewall102is opposite to the fourth sidewall104. In an embodiment, the first sidewall101is parallel to the third sidewall103, and the second sidewall102is parallel to the fourth sidewall104. The room10is substantially rectangular. The first sidewall101, the second sidewall102, the third sidewall103, and the fourth sidewall104cooperatively define a receiving space11.

In an embodiment, the first barrier20and the second barrier21are disposed in the receiving space11. The first barrier20is fixed to the third sidewall103. The second barrier21is fixed to the first sidewall101. The first barrier20and the second barrier21are not in line with each other. That is, the first barrier20and the second barrier21are located on different planes. Therefore, the first barrier20and the second barrier21divide the receiving space11into a plurality of channels12connected to each other. The channels12are arranged in a zigzag manner (such as a snakelike manner shown inFIG. 2).

In an embodiment, only one first barrier20and only one second barrier21are included in the receiving space11. In other embodiments, the numbers of the first and second barriers20and21in the receiving space11may be more than one. Along a direction from the second sidewall102to the fourth sidewall104, a plurality of the first barrier20and a plurality of the second barrier21are alternately arranged.

When objects pass through the receiving space11, the objects need to pass through the channels12, thereby forcing the objects to spend more time inside the receiving space11. Thus, a better effect of air or other gas being blown out is obtained.

Referring toFIG. 2, each of the channels12includes at least one air jet30. The air jet30may be a rotary air jet. In an embodiment, the air jet30may be disposed on the second sidewall102, the fourth sidewall104, both sides of the first barrier20, or both sides of the second barrier21. In an embodiment, the air jet30disposed on the second sidewall102is opposite to the first barrier20. The air jet30disposed on the fourth axis104is opposite to the channel12between the second barrier21and the first sidewall101. Gas can be blown out from the air jet30, which cleans away the dust particles on the objects.

The two revolving doors40are installed at two ends of the channels12. In an embodiment, one of the revolving doors40is fixed to one end of the second sidewall102adjacent to the first sidewall101. The other revolving door40is fixed to one end of the fourth sidewall104adjacent to the third sidewall103. The revolving door40includes an outer frame401fixed to the sidewall and a door body402. The door body402is disposed in the outer frame401and can be rotated in the outer frame401. The outer frame401includes two opposite openings4011, and the objects can enter and exit the air shower device100only through the openings4011.

In the embodiment, the two revolving doors40are each a three-leaf structure, the three leaves revolving on a single axis at120degrees to each other. The outer frame401of one of the revolving doors40is bonded between the first sidewall101and the second sidewall102by an adhesive50. The outer frame401in the other of the revolving doors40is bonded between the third sidewall103and the fourth sidewall104by the adhesive50. There is no gap between the door body402and the outer frame401. Thereby, the two revolving doors40are always closed to prevent ingress of dust, wind, water and noise from outside. The revolving doors40can also prevent the cold air in the receiving space11from leaking out and so can maintain a certain temperature and humidity in the receiving space11. The two revolving doors40are not interlocked. The door body402rotates in one single direction, which allows different objects to enter and exit from the two revolving doors40at the same time, thereby avoiding the objects getting stuck near the revolving doors40. The door body402rotates according to a manual mode or an automatic mode. In the embodiment, the door body402rotates according to the manual mode, so that people can open and close the door body402by themselves, thereby increasing the safety of the revolving door40. The revolving door40does not require a power supply and a door closer in the manual mode, that is, the revolving door40has simple structure.

In the present disclosure, the first barrier20and the second barrier21defines the receiving space11into the channels12. When objects pass through the receiving space11, the objects need to pass through the channels12, thereby causing the objects to spend a certain amount of time in the receiving space11. Thus, a better effect of the blown air is obtained.

It is to be understood, even though information and advantages of the present exemplary embodiments have been set forth in the foregoing description, together with details of the structures and functions of the present exemplary embodiments, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size, and arrangement of parts within the principles of the present exemplary embodiments to the full extent indicated by the plain meaning of the terms in which the appended claims are expressed.
