Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0038] Reference Figures 1 to 7 As shown, the air-drying device according to an embodiment of the present application includes:

[0039] Housing 100;

[0040] The fan 110 is disposed inside the housing 100 and is used to extract external air;

[0041] The filter device 300 is disposed inside the housing 100 and connected to the air outlet of the fan 110 to filter the external air;

[0042] The air drying seat 200 is arranged on one side of the housing 100, and an air outlet cavity 203 is opened inside the air drying seat 200. An air outlet 204 is opened at one end of the air drying seat 200, and the air outlet 204 is connected to the air outlet cavity 203. A plurality of mounting seats 210 are arranged inside the air outlet cavity 203, and the interior of the mounting seat 210 is connected to the filter device 300. An air outlet seat 220 is arranged on one side of the mounting seat 210, and the interior of the air outlet seat 220 is connected to the interior of the mounting seat 210. A diverter seat 226 is arranged on one side of the air outlet seat 220, and a plurality of diverter bumps are arranged on both sides of the diverter seat 226. 223, the diverter protrusion 223 divides the air outlet cavity 203 into a first air outlet channel 201 and a second air outlet channel 202, the first air outlet channel 201 and the second air outlet channel 202 are connected to the air outlet 204, adjacent diverter protrusions 223 are separated to form diverter intervals 225, the diverter intervals 225 are connected to the first air outlet channel 201 and the second air outlet channel 202, a plurality of first air outlet holes 222 are opened on one side of the air outlet seat 220, the first air outlet holes 222 are connected to the interior of the air outlet seat 220, and the plurality of first air outlet holes 222 are respectively facing the plurality of diverter protrusions 223.

[0043] It can be understood that when the fan 110 is started, the fan 110 draws external air into the filter device 300, and the filter device 300 filters the dust in the air and then transports the air to multiple mounting seats 210. The filtered air passes through the interior of the mounting seat 210 and the interior of the air outlet seat 220 and is ejected from the first air outlet 222. Since the first air outlet 222 is respectively facing the diversion protrusion 223, the air will be diverted by the diversion protrusion 223 after being ejected, so that part of the air is transported to the first air outlet channel 201 through the diversion interval 225, and the other part of the air is transported to the second air outlet channel 202. Under the guidance of the first air outlet channel 201 and the second air outlet channel 202, the air is ejected from the air outlet 204, providing two wind directions, thereby increasing the drying area of ​​the PCB board and avoiding uneven drying of water on the PCB board surface and the inner hole of the PCB board.

[0044] In addition, water will adhere to the surface of the PCB board after cleaning. Therefore, if dust is sprayed out during air drying, a large amount of dust will adhere to the surface of the PCB board. In order to reduce the generation of dust, the fan 110 will first connect the filter device 300 when drawing external air. The filter device 300 filters the dust, thereby greatly reducing the generation of dust and preventing the fan 110 from blowing dust onto the surface of the PCB board.

[0045] Reference Figures 1 to 6 As shown, according to some embodiments of the present application, the filtering device 300 includes a support plate 310, a first connecting seat 320, a second connecting seat 340 and a filter seat 330, the interior of the filter seat 330 is loaded with filtering material, the support plate 310 is installed inside the casing 100, the first connecting seat 320, the second connecting seat 340 and the filter seat 330 are installed on one side of the support plate 310, the filter seat 330 is respectively located between the first connecting seat 320 and the second connecting seat 340, the interior of the first connecting seat 320 is connected to the interior of the filter seat 330 and the interior of the mounting seat 210, and the interior of the second connecting seat 340 is connected to the interior of the filter seat 330 and the air outlet end of the fan 110.

[0046] It can be understood that when the fan 110 draws external air into the filter device 300, the air will pass through the interior of the first connecting seat 320, the interior of the filter seat 330 and the interior of the second connecting seat 340 in sequence. The interior of the filter seat 330 is loaded with filter material, which facilitates the filtering of dust in the air, thereby preventing dust from being blown out from the air outlet 204.

[0047] In addition, the filter material inside the filter seat 330 can be glass fiber filter cotton, activated carbon filter cotton, synthetic fiber filter cotton, non-woven filter cotton, paper filter element, sponge, etc.

[0048] Reference Figures 5 and 6As shown, according to some embodiments of the present application, a plurality of first ventilation holes 321 are provided at one end of the first connecting seat 320, and the plurality of first ventilation holes 321 are connected to the interior of the first connecting seat 320; second ventilation holes 331 are provided at both ends of the filter seat 330, and the plurality of first ventilation holes 321 are connected to the second ventilation holes 331 at one end of the filter seat 330; a plurality of third ventilation holes 341 are provided at one end of the second connecting seat 340, and the plurality of third ventilation holes 341 are connected to the interior of the second connecting seat 340, and the plurality of third ventilation holes 341 are connected to the second ventilation holes 331 at the other end of the filter seat 330.

[0049] It can be understood that when air flows through the first connecting seat 320, the air flows through the first ventilation hole 321 of the first connecting seat 320 to the second ventilation hole 331 at one end of the filter seat 330. When passing through the filter material inside the filter seat 330, the air will flow from the second ventilation hole 331 at the other end of the filter seat 330 to the third ventilation hole 341 of the second connecting seat 340, thereby facilitating the guidance and transportation of air containing dust.

[0050] Reference Figures 5 and 6 As shown, according to some embodiments of the present application, movable handles 344 are hinged on both sides of the first connecting seat 320, a lap frame 345 is hinged on one side of the movable handle 344, a lap opening 346 is opened inside the lap frame 345, and fixed ears 342 are provided on both sides of the second connecting seat 340, and a lap protrusion 343 is provided on one side of the fixed ear 342. When the lap opening 346 passes through the adjacent lap protrusion 343, the movable handle 344 rotates so that the lap opening 346 overlaps with the lap protrusion 343.

[0051] It can be understood that when the filter seat 330 is installed, the filter seat 330 is placed between the first connecting seat 320 and the second connecting seat 340, the overlapping opening 346 passes through the adjacent overlapping protrusions 343, and the movable handle 344 is rotated so that the overlapping opening 346 overlaps with the overlapping protrusions 343, so that the first connecting seat 320 and the second connecting seat 340 can clamp the filter seat 330 to facilitate the installation of the filter seat 330; when the filter material inside the filter seat 330 needs to be replaced, the movable handle 344 is rotated so that the overlapping opening 346 is disengaged from the overlapping protrusions 343, thereby facilitating the filter seat 330 to be disengaged from the clamping of the first connecting seat 320 and the second connecting seat 340.

[0052] Reference Figures 5 and 6 As shown, according to some embodiments of the present application, a first sealing gasket 332 is provided on one side of the filter seat 330 , the first sealing gasket 332 is elastic, and the first sealing gasket 332 abuts against one end of the first connecting seat 320 .

[0053] It can be understood that when the first connecting seat 320 and the second connecting seat 340 clamp the filter seat 330, the first sealing gasket 332 has elasticity so that the first sealing gasket 332 contacts one end of the first connecting seat 320, thereby preventing air from flowing out of the gap between the first connecting seat 320 and the filter seat 330.

[0054] Reference Figures 5 and 6 As shown, according to some embodiments of the present application, a second sealing gasket 333 is provided on the other side of the filter seat 330 , the second sealing gasket 333 is elastic, and the second sealing gasket 333 abuts against one end of the second connecting seat 340 .

[0055] It can be understood that when the first connecting seat 320 and the second connecting seat 340 clamp the filter seat 330, the second sealing gasket 333 has elasticity so that the second sealing gasket 333 contacts one end of the second connecting seat 340, thereby preventing air from flowing out from the gap between the second connecting seat 340 and the filter seat 330.

[0056] Reference Figure 7 As shown, according to some embodiments of the present application, a plurality of second air outlet holes 224 are opened on one side of the diverter seat 226, the second air outlet holes 224 are connected to the interior of the diverter seat 226, the interior of the diverter seat 226 is connected to the interior of the air outlet seat 220, and the second air outlet holes 224 are connected to the first air outlet channel 201.

[0057] It is understandable that when air enters the interior of the air outlet seat 220 , part of the air will flow into the interior of the diverter seat 226 and be discharged from the second air outlet hole 224 , thereby facilitating increasing the air output of the first air outlet channel 201 .

[0058] Reference Figure 2 As shown, according to some embodiments of the present application, the air inlet end of the fan 110 is connected to the air inlet pipe 111, which is connected to the outside, and the air outlet end of the fan 110 is connected to the first connecting pipe 112, which is connected to the interior of the first connecting seat 320. One side of the second connecting seat 340 is connected to the second connecting pipe 113, which is connected to the interior of the mounting seat 210.

[0059] It can be understood that the fan 110 draws air into the first connecting pipe 112 through the air inlet pipe 111. After passing through the first connecting seat 320, the air flows in sequence to the interior of the first connecting seat 320, the interior of the filter seat 330 and the interior of the second connecting seat 340, and finally flows to the mounting seat 210 through the second connecting pipe 113, thereby facilitating the guidance of the air flow direction.

[0060] Reference Figures 2 to 5As shown, according to some embodiments of the present application, a wind pressure display 114 and a wind pressure regulating valve 115 are connected to one side of the second connecting pipe 113, the wind pressure display 114 is used to detect the wind pressure inside the second connecting pipe 113, and the wind pressure regulating valve 115 is used to adjust the wind pressure of the second connecting pipe 113.

[0061] It can be understood that when air flows to the second connecting pipe 113, the wind pressure inside the second connecting pipe 113 can be conveniently displayed through the wind pressure display 114. When the wind pressure is relatively large or relatively small, the wind pressure of the second connecting pipe 113 can be conveniently adjusted through the wind pressure regulating valve 115 to control the air output of the air outlet 204.

[0062] Reference Figure 7 As shown, according to some embodiments of the present application, a guide arc surface 221 is formed on one side of the air outlet seat 220 , the first air outlet 222 is located inside the guide arc surface 221 , and the concave surface of the guide arc surface 221 faces the diversion protrusion 223 .

[0063] It is understandable that when air is ejected from the first air outlet 222 , it passes through the concave surface of the guide arc surface 221 toward the diverter protrusion 223 , thereby facilitating the air to be blown to the diverter protrusion 223 , so that the diverter protrusion 223 can divert the air.

[0064] The embodiments of the present application are described in detail above in conjunction with the accompanying drawings, but the present application is not limited to the above embodiments. Various changes can be made within the knowledge of ordinary technicians in the relevant technical field without departing from the purpose of the present application. In addition, the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
