Description

Technical Field

[0001] This utility model relates to the field of air circulation and purification technology, specifically to an air circulation and purification mechanism for a laptop shell paint spraying box. Background Technology

[0002] A laptop computer, or simply a notebook, is characterized by its small size. More portable than a desktop computer, it's a small, easily portable personal computer. During the laptop manufacturing process, to extend its lifespan, the laptop casing is placed in a paint spraying box and its surface is painted before component assembly, thus improving the laptop's protective properties.

[0003] When painting laptops inside a spray booth, a large amount of exhaust gas is easily generated. If this exhaust gas cannot be absorbed and filtered quickly enough, it can be inhaled by workers. Therefore, air circulation and purification devices are usually installed inside spray booths to purify the exhaust gas. Commonly, this involves spraying water through a hose inside the booth to purify and absorb the exhaust gas, thus achieving air purification. However, the wastewater after spraying contains certain harmful substances, and direct discharge can easily harm the environment and waste resources. Utility Model Content

[0031] This utility model provides an air circulation and purification mechanism for the paint spraying box of a laptop casing. The specific working principle is as follows:

[0032] When painting the laptop casing, the suction motor 702 is activated, causing its output shaft to drive the fan gear 703 to rotate rapidly. This draws the exhaust gas from the paint spraying box into the spray box 3 through the air inlet 6.

The pre-filtered exhaust gas then enters the space between the spray box 3 and the connecting plate 11 through the air inlet 12. The water pump 9 is activated, transporting water from the water tank 10 to the spray pipe 13 through the water inlet pipe 8. The water is then sprayed through the nozzles on the spray pipe 13 to spray the pre-filtered exhaust gas, absorbing dust and harmful substances. The exhaust gas then enters the purification system through the air inlet 15. In box 14, the exhaust gas is further treated by the second filter screen 16 and the second activated carbon layer 17. After purification, the exhaust gas escapes through the air outlet 19. At the same time, the used wastewater enters the recycling box 402 through the water outlet pipe 401. The activated carbon layer 405 adsorbs foreign objects and harmful substances in the wastewater and enters the area below the mounting frame 404. The pump 407 is started, and the treated wastewater can be transported back to the spray pipe 13 through the connecting pipe 408 for reuse, thereby improving the utilization rate of resources. Pulling the handle 406 can remove the mounting frame 404 and the activated carbon layer 405 from the guide rail 403 for replacement of the activated carbon layer 405.
