DETAILED DESCRIPTION OF THE EMBODIMENTS
[0020] The following further elaborates on the present application in conjunction with the attached Figures 1 - 4 for a more detailed description of the present application.
[0021] The embodiment of the present application discloses a ventilation structure applicable to a spray booth. Refer to Figures 1 - 4, A ventilation structure suitable for a spray booth, including an air duct body 1. A fan assembly is installed at the center of the interior of the air duct body 1. At both ends of the inner wall of the air duct body 1, a first positioning ring 9 and a second positioning ring 12 are respectively fixed. The fan assembly is located between the first positioning ring 9 and the second positioning ring 12; it also includes a first filter cartridge 3 and a second filter cartridge 8. The first filter cartridge 3 is sleeved at one end of the air duct body 1, and the first filter cartridge 3 is connected to the first positioning ring 9. The second filter cartridge 8 is sleeved at the other end of the air duct body 1, and the second filter cartridge 8 is connected to the second positioning ring 12. An installation hole adapted to the air duct body 1 is preset on the wall of the spray booth, and the air duct body 1 is installed therein, with the first filter cartridge 3 facing the interior of the booth and the second filter cartridge 8 facing the exterior of the booth. Starting the fan assembly can send air in real time, so as to make air convection and reduce the harm caused by spraying.
[0022] In this embodiment, as Figure 1 and Figure 2 shown, one side of both the first filter cartridge 3 and the second filter cartridge 8 is an opening, and the other side is a closed surface provided with a plurality of filter holes. The opening of the first filter cartridge 3 faces the fan assembly, and the opening of the second filter cartridge 8 faces away from the fan assembly. The first filter cartridge 3 is located inside the factory building, and the second filter cartridge 8 is located outside the factory building. An installation ring 2 is sleeved and fixed on the outer surface of the air duct body 1, and the installation ring 2 is located in the preset hole in the wall. Pulling buttons 4 are fixed on both the first filter cartridge 3 and the second filter cartridge 8. Two collar rings 6 are respectively fixed on the outer surface of the air duct body 1 through a plurality of fastening bolts 7, and the two collar rings 6 are respectively located at both ends of the air duct body 1. On the two collar rings 6, a plurality of limiting members 5 are installed through damping rotating shafts, and the limiting members 5 can be respectively connected to the first filter cartridge 3 or the second filter cartridge 8.
[0023] When disassembling and cleaning, rotate the limiting members 5 respectively to make them deviate from the first filter cartridge 3 or the second filter cartridge 8. Then, the first filter cartridge 3 or the second filter cartridge 8 is released from the limit. Pulling the pulling button 4 outwards can slide the first filter cartridge 3 or the second filter cartridge 8 out. The disassembly is convenient and fast, reducing the labor consumption and facilitating the improvement of the maintenance efficiency of this ventilation structure.
[0024] In this embodiment, as Figure 3 and Figure 4 shown, a second chamfer 11 is provided at the open end of the first filter cartridge 3, and a first chamfer 10 is provided on the closed surface of the second filter cartridge 8. The setting of the chamfer is convenient for reducing the friction force, so that the first filter cartridge 3 or the second filter cartridge 8 can be more smoothly sleeved inside the air duct body 1, facilitating the installation operation.
[0025] The implementation principle of a ventilation structure applicable to a spray booth in an embodiment of the present application is as follows: During disassembly and cleaning, the limiting members 5 are rotated respectively to deviate from the first filter cartridge 3 or the second filter cartridge 8. As a result, the first filter cartridge 3 or the second filter cartridge 8 is released from the limit. By pulling the pull button 4 outwards, the first filter cartridge 3 or the second filter cartridge 8 can be slid out. The disassembly is convenient and fast, reducing the labor consumption and facilitating the improvement of the maintenance efficiency of the ventilation structure. By providing the first filter cartridge 3 and the second filter cartridge 8, the two filter cartridges are respectively located at both ends of the air duct, so that impurities can be filtered when the air enters and exits the air duct, further improving the filtration efficiency. Moreover, when one of the filter cartridges is disassembled for cleaning, the other filter cartridge can also perform a temporary filtering function, enabling the fan assembly to continue to supply air and ensuring continuous ventilation in the workshop, thus improving the practicability.
