These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0029] According to an embodiment of the present invention, a ventilation device for a cleanroom is provided.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-4 As shown, a cleanroom ventilation device according to an embodiment of the present utility model includes an audible and visual alarm mounting housing 1, a smoke-assisted exhaust ventilation component 2 is provided inside the audible and visual alarm mounting housing 1, a circulation purification component 3 is provided on one side of the smoke-assisted exhaust ventilation component 2, and a fire audible and visual alarm component 4 is provided on one side of the circulation purification component 3.

[0031] like Figure 1-4As shown, the smoke-assisted exhaust ventilation assembly 2 includes an exhaust mounting housing 201. A fresh air duct 210 is connected to one side of the exhaust mounting housing 201. A fresh air shut-off valve 211 is installed inside the fresh air duct 210. A smoke exhaust pipe 212 is connected to one side of the fresh air duct 210. A smoke exhaust valve 213 is installed inside the smoke exhaust pipe 212. The exhaust mounting housing 201 is connected to the audible and visual alarm mounting housing 1. A temperature sensor 202 is located around the exhaust mounting housing 201. A smoke sensor 203 is located on one side of the temperature sensor 202. The smoke sensor 203 and the temperature sensor 202 are connected to the exhaust mounting housing 201. A duct mounting bracket 204 is located inside the exhaust mounting housing 201. The duct mounting bracket 204 is connected to... The audible and visual alarm mounting housing 1 is connected to the air guide mounting bracket 204, which contains an air guide fan 205. An electric heating plate 214 is provided on one side of the air guide mounting bracket 204. A smoke exhaust pipe 206 and a purification circulation pipe 207 are respectively connected to one side of the air guide mounting housing 201. A smoke exhaust valve 208 is installed inside the smoke exhaust pipe 206, and a purification circulation valve 209 is installed inside the purification circulation pipe 207.

[0032] Through the above technical solution, by setting the exhaust mounting housing 201, the purpose of facilitating the installation of temperature sensor 202 and smoke sensor 203 is achieved. Temperature sensor 202 and smoke sensor 203 determine whether a fire has occurred. When no fire has occurred, the exhaust fan 205 in the exhaust mounting bracket 204 introduces fresh air into the exhaust mounting housing 201 through the fresh air duct 210. The air is heated and dried by the electric heating plate 214. The dried air then enters the purification circulation pipe 207, which introduces the dried air into the circulation purification component 3 for purification. In the event of a fire, temperature sensor 202 and smoke sensor 203, through the PLC controller 5, cause the purification circulation valve 209 to close, the smoke exhaust valve 208 to open, and the smoke exhaust valve 213 to close. The smoke exhaust valve 213 is then opened, allowing smoke to enter the audible and visual alarm mounting housing 1 through the smoke exhaust pipe 212. Finally, the smoke is discharged to the outside through the smoke exhaust pipe 206.

[0033] like Figure 1-4 As shown, the circulating purification component 3 includes a purification installation housing 301, a dust filter 302 is installed inside the purification installation housing 301, an activated carbon adsorption plate 303 is provided on one side of the dust filter 302, an air filter element 304 is provided on one side of the activated carbon adsorption plate 303, and an exhaust port 6 is opened on one side of the purification installation housing 301.

[0034] The above technical solution, by setting up a purification installation shell 301, facilitates the installation of dust filter 302, activated carbon adsorption plate 303 and air filter element 304. Dust filter 302 filters dust, activated carbon adsorption plate 303 adsorbs harmful substances, and air filter element 304 improves air purification. By setting up an exhaust port 6, purified air can be easily discharged.

[0035] like Figure 1-4 As shown, the fire alarm assembly 4 includes an alarm light 401, which is installed inside the alarm mounting housing 1. An alarm buzzer 402 is provided on one side of the alarm light 401, and a sound transmission slot 403 is provided on one side of the alarm buzzer 402. A dust filter 404 is installed inside the sound transmission slot 403. The alarm light 401 and the alarm buzzer 402 are electrically connected to the PLC controller 5.

[0036] Through the above technical solution, by setting up an alarm light 401 and an alarm buzzer 402, the PLC controller 5 will activate the alarm light 401 and the alarm buzzer 402 when a fire occurs, thereby achieving the purpose of fire sound and light alarm. The sound transmission groove 403 facilitates the sound alarm of the alarm buzzer 402, and the dust filter 404 prevents dust from entering the sound and light alarm housing 1.

[0037] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0038] Working principle: By setting the exhaust mounting housing 201, the temperature sensor 202 and smoke sensor 203 are easily installed. The temperature sensor 202 and smoke sensor 203 determine whether a fire has occurred. When no fire has occurred, the exhaust fan 205 in the exhaust mounting bracket 204 introduces fresh air into the exhaust mounting housing 201 through the fresh air duct 210. The air is heated and dried by the electric heating plate 214. The dried air then enters the purification circulation pipe 207, which in turn introduces the dried air into the circulation purification component 3 for purification. In the event of a fire, the temperature sensor 202 and smoke sensor 203, through the PLC controller 5, cause the purification circulation valve 209 to close, the smoke exhaust valve 208 to open, and the smoke exhaust valve 213 to close. The smoke exhaust valve 213 is then opened, allowing the smoke to enter the audible and visual alarm mounting housing 1 through the smoke exhaust pipe 212. Finally, the smoke is discharged to the outside through the smoke exhaust pipe 206.

[0039] By setting up the purification installation housing 301, it is possible to facilitate the installation of the dust filter 302, the activated carbon adsorption plate 303 and the air filter element 304. The dust filter 302 filters dust, the activated carbon adsorption plate 303 adsorbs harmful substances, and the air filter element 304 improves air purification. By setting up the exhaust port 6, it is possible to facilitate the discharge of purified air.

[0040] By setting up alarm lighting 401 and alarm buzzer 402, the PLC controller 5 can activate alarm lighting 401 and alarm buzzer 402 when a fire occurs, thereby achieving the purpose of fire sound and light alarm. The sound transmission groove 403 facilitates the sound alarm of alarm buzzer 402, and the dust filter 404 prevents dust from entering the sound and light alarm housing 1.
