[0002] In many industries, such as medical, pharmaceutical, electronics and semiconductor manufacturing, cleanrooms are widely used in workplaces that require a highly clean environment. The main goal of a cleanroom is to control the concentration of particles, bacteria and other harmful substances in the environment to ensure the quality of the production process and the safety of the product. In order to achieve this goal, the cleanroom must take appropriate ventilation measures to effectively control particulate matter and pollutants in the air.

[0003] At present, when a clean room is built, ventilation channels are built in advance to ensure a clean indoor environment and avoid the growth of bacteria. However, clean rooms usually lack a good ventilation system, and the dirty air in the clean room is directly discharged to the outside, resulting in a poor air environment around the clean room. Clean rooms generally exchange air through simple ventilation windows, which do not have the function of purifying dirty air, and because moisture is mixed in the air, it is easy to cause mold to grow on the ventilation windows.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The ventilation device of the present invention is a ventilation window structure, which is composed of an outer window and an inner window. The window is installed on the wall of the clean room and can exchange air between the clean room and the outside. A protective net is arranged on it, and the window can be closed by a closing plate. When it is necessary to stop the air exchange, the driving rope is pulled by the pull ring, and the closing plate is driven to rotate by the driving rope to close the channel.

[0016] 2. The present invention provides a purification structure in the channels of the inner window and the outer window. The installation frame with the purification board is inserted into the inner window through the slot position, which can adsorb the particles carrying odor in the polluted air, so that the air is discharged after being purified, thereby ensuring the air environment around the clean room. The purification structure is fixed by a positioning structure, and the positioning structure is easy to unlock. After the purification board has been used for a period of time, the installation frame can be quickly disassembled to clean the purification board.

[0017] 3. The present invention takes into account that the humidity of the air in the clean room is relatively high, and moisture can easily carry bacteria into the purification board, causing the purification board to mold and deteriorate. Therefore, a heating net is installed in the outer window through a movable bracket. Under normal circumstances, the heating net is attached to the purification board to heat the purification board to prevent the purification board from being damp and moldy, thereby increasing the service life of the purification board. When replacing the purification board, the heating net can move away from the purification board with the bracket to prevent the purification board from falling. The pressure of the closing plate is transmitted to the transmission assembly through the translation rod, and then the transmission assembly is used to drive the heating net away from the purification board, and the pressure rod on the translation rod is used to unlock the positioning structure, so that when the closing plate is closed, the heating net first separates from the purification board and then the purification board automatically falls.

A slide bar 26 is slidably installed in the mounting groove 24 , and a bracket 27 is installed on the slide bar 26 . A heating net 28 is installed at the front end of the bracket 27 .

[0042] Considering that the humidity of the air in the clean room is relatively high, the moisture generated can easily carry bacteria into the purification board 16, causing the purification board 16 to mold and deteriorate. In the present invention, a heating net 28 is installed in the outer window 1 through a movable bracket 27. Under normal circumstances, the heating net 28 is attached to the purification board 16 to heat the purification board 16 to prevent the purification board 16 from being damp and moldy, thereby increasing the service life of the purification board 16. When replacing the purification board 16, the heating net 28 can move away from the purification board 16 with the bracket 27 to prevent the purification board 16 from falling.

[0047] When the present invention is in use: first, the ventilation device of the present invention is a ventilation window structure, which is composed of an outer window 1 and an inner window 2 to form a window, which is installed on the wall of the clean room and can exchange air between the clean room and the outside world. A protective net 3 is arranged on it, and the window can be closed by a closing plate 6. When it is necessary to stop the air exchange, the driving rope 7 is pulled by the pull ring 9, and the closing plate 6 is driven to rotate by the driving rope 7 to close the channel. After the closing plate 6 overcomes the elastic force of the elastic rotating shaft 4 and is closed, the driving rope 7 and the closing plate 6 can be fixed by a rope fixing structure. First, the driving rope 7 is clamped by a pair of spring clamps 11, and then the driving rope 7 is wound around the rope winding rod 13 and fixed by tying a knot.

The purification structure is fixed with a positioning structure, and the positioning structure is easy to unlock. After the purification board 16 has been used for a period of time, the installation frame 15 can be quickly disassembled to clean the purification board 16. The end of the positioning plug-in 20 is provided with a rounded corner. When the installation frame 15 is inserted into the slot 14, the installation frame 15 can first push the positioning plug-in 20 back to overcome the elastic force of the positioning spring 21, and then when the installation frame 15 is fully inserted, the positioning plug-in 20 can be inserted into the positioning The mounting frame 15 and the purification board 16 are fixed in the groove 18. When replacement is needed, the unlocking lever 23 is pressed to drive the unlocking lever 23 to rotate, and the ear hook 22 is pushed by the end of the unlocking lever 23 to drive the positioning plug-in 20 to disengage from the positioning groove 18, so that the purification structure falls directly under the action of gravity. Considering that the humidity of the air in the clean room is relatively high, moisture can easily carry bacteria into the purification board 16, causing the purification board 16 to mold and deteriorate. In the present invention, a heating net 28 is installed in the outer window 1 through a movable bracket 27. Under normal circumstances, the heating net 28 is attached to the purification board 16 to heat the purification board 16 to prevent the purification board 16 from being damp and moldy, thereby increasing the service life of the purification board 16. When replacing the purification plate 16, the heating net 28 can move away from the purification plate 16 with the bracket 27 to prevent the purification plate 16 from falling. The pressure of the closing plate 6 is transmitted to the transmission assembly through the translation rod 30, and then the transmission assembly is used to drive the heating net 28 away from the purification plate 16, and the pressure rod 35 on the translation rod 30 is used to unlock the positioning structure, so that when the closing plate 6 is closed, the heating net 28 first separates from the purification plate 16, and then the purification plate 16 automatically falls off. When the closing plate 6 is rotated and closed, the translation rod 30 can be pushed inward, so that the driving rack 31 on the translation rod 30 drives the steering gear 33 to rotate, and then the connecting rack 34 and the bracket 27 are driven to move through the steering gear 33, so that the heating net 28 is separated from the purification plate 16.Then, the pressure rod 35 at the front end of the translation rod 30 presses on the unlocking lever 23, and the restriction on the mounting frame 15 is cancelled by the unlocking lever 23, so that the mounting frame 15 and the purification plate 16 fall down.
