Description

Technical Field

[0001] This invention belongs to the field of controller technology, and specifically discloses a waterproof and dustproof industrial fan controller. Background Technology

[0002] Industrial fans, due to their larger fan diameter, have a larger blowing area compared to traditional ceiling fans. They are also widely used in workshops, warehouses, and gyms in recent years because of their quiet operation, energy efficiency, and safety features. However, industrial fans require a controller for operation. The industrial fan controller is the core device for regulating the fan's operating status, enabling speed adjustment, start / stop control, timer settings, and fault protection. It adapts to the airflow requirements of different industrial scenarios, improves equipment operating efficiency, reduces energy consumption, and ensures stable and reliable fan operation.

[0003] In the existing technology, industrial fan controllers are generally equipped with cooling fans to dissipate heat from the controller. Although the casing of current controllers is generally waterproof, this type of heat dissipation can easily allow dust to enter the controller. At the same time, as air enters, moisture in the air will inevitably enter the controller, resulting in the generation of water vapor inside the controller. Dust and water vapor can damage the controller and reduce its service life. Summary of the Invention

[0019] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Numerous specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the invention is not limited to the specific embodiments disclosed below.

[0021] like Figures 1-8 The illustrated industrial fan controller includes a fan control device 1. A dehumidification and cooling mechanism 2 is externally mounted on the fan control device 1. The dehumidification and cooling mechanism 2 is used for heat dissipation, dehumidification, and dust prevention for the fan control device 1. An inflation protection mechanism 4 is externally mounted on the fan control device 1. An air path conversion mechanism 3 is mounted at the top of the inflation protection mechanism 4. The air path conversion mechanism 3 is used to convert the air path. The inflation protection mechanism 4 is used to protect the fan control device 1. A single power unit can achieve the functions of heat dissipation, dehumidification, dust prevention, and protection, fully utilizing the power of the power unit and thus achieving energy saving.

[0022] The dehumidification and cooling mechanism 2 includes a miniature air pump 201, which is externally fixedly connected to the side wall of the fan control device 1. An air inlet pipe 202 is fixedly connected to the input end of the miniature air pump 201, serving a ventilation function. A mounting shell 203 is fixedly connected to the top end of the air inlet pipe 202, providing an installation position. Two locking strips 204 are externally fixedly connected to the mounting shell 203. A mounting cover 205 is provided on the top of the mounting shell 203, and an inner shell 206 is fixedly connected to the top end of the mounting cover 205, providing a mounting position. The inner shell 206 has a retaining spring 207 inside, and a limit ring 208 is slidably connected inside the inner shell 206. The limit ring 208 has a limiting function, and a retaining ring 209 is fixedly connected to the bottom of the limit ring 208. Two locking blocks 210 are fixedly connected to the inner wall of the mounting cover 205. The locking blocks 210 engage with the locking strip 204. A ventilation pipe 211 is fixedly connected to the output end of the micro air pump 201. A heat dissipation fin 216 is fixedly connected to one side wall of the fan control device 1. The heat dissipation fin 216 can assist in heat dissipation. The ventilation pipe 211 is set... Inside the heat sink 216, an air intake head 212 is fixedly connected to the top of one side of the fan control device 1. A connecting hose 213 is fixedly connected to the top of the air intake head 212. An exhaust dust filter cover 214 is fixedly connected to the bottom of the fan control device 1 on the same side as the air intake head 212. An inlet hose 215 is fixedly connected to the end of the ventilation pipe 211 away from the micro air pump 201. A filter element 217 is installed inside the mounting shell 203. The filter element 217 contains water-absorbing substances such as silica gel, molecular sieve, activated alumina, anhydrous calcium chloride, and phosphorus pentoxide. It can absorb moisture in the air, thereby drying the air. At the same time, the outer shell of the filter element 217 can filter, preventing dust or other impurities from entering the fan control device 1. The retaining ring 209 can use the reaction force of the retaining spring 207 to press tightly against the top of the filter element 217, thereby firmly installing the filter element 217 inside the mounting shell 203. One end of the retaining spring 207 is fixedly connected to the top of the inner shell 206, and the other end of the retaining spring 207 is fixedly connected to the top of the limiting ring 208. When the fan control device 1 is activated, the input end of the fan control device 1 generates suction, which is transmitted to the inside of the mounting housing 203 through the air intake pipe 202. The outside air is filtered by the filter element 217 inside the mounting housing 203. The filtered air is transmitted to the inside of the ventilation pipe 211 through the output end of the micro air pump 201, and then transmitted to the inside of the connecting hose 213 through the inlet hose 215 and the air path conversion mechanism 3. The air is then transmitted to the inside of the air intake head 212 through the connecting hose 213. The air intake head 212 transmits the filtered air to the inside of the fan control device 1, thereby cooling the fan control device 1. The air is then discharged through the exhaust dust cover 214, which removes the humid air inside the fan control device 1, thus protecting the electronic components inside the fan control device 1. When replacing the filter element 217, first press the mounting cover 205 downwards, which will move the inner shell 206 downwards and compress the retaining spring 207. At this time, the locking block 210 moves downwards out of the groove in the middle of the locking strip 204. Then, rotate the mounting cover 205, which will cause the locking block 210 to rotate. When the locking block 210 rotates to the unconnected position between the two locking strips 204, the mounting cover 205 can be removed from the mounting shell 203. When installing the filter element 217, after placing the new filter element 217 inside the mounting shell 203, remove the locking block 210 from the mounting cover 205. 10 Align the unconnected part between the two locking strips 204 and slide it under the locking strip 204. Rotate the mounting cover 205. When the locking block 210 rotates to the groove of the locking strip 204, release the mounting cover 205. Under the reaction force of the clamping spring 207, the inner shell 206 and the mounting cover 205 will move upward, so that the locking block 210 can be hung in the groove of the locking strip 204. At this time, the clamping spring 207 is not fully extended, so it can give the limiting ring 208 and the clamping ring 209 a downward force, so that the clamping ring 209 can press against the filter element 217, thus completing the installation of the filter element 217.

[0023] The gas path conversion mechanism 3 includes a cylinder 301, which provides an installation position and allows for air passage. A baffle 302 is installed inside the cylinder 301 to block gas and thus change its path. A movable pipe 303 is fixedly connected to the bottom of the baffle 302. Multiple vent holes 304 are provided at the top of the movable pipe 303, allowing air to enter the interior of the movable pipe 303. Multiple limiting devices are fixedly connected to the outside of the movable pipe 303. The limiting strip 305 and the moving tube 303 are slidably connected to a rotating sleeve 306. After the limiting strip 305 slides inside the rotating sleeve 306, it prevents the moving tube 303 from rotating when the cylinder 301 rotates. A fixing ring 307 is fixedly connected to the bottom of the moving tube 303. A return spring 308 is provided on the outside of the moving tube 303. An outer sleeve 309 is fixedly connected to the bottom of the cylinder 301. A torsion spring 310 is sleeved on the outside of the rotating sleeve 306. The outer sleeve 309 can rotate... The compression torsion spring 310 is fixedly connected to the bottom of the outer casing 309 with two locking ears 311. The outer casing 307 is fixedly connected to two locking brackets 312. An air inlet branch pipe 313 is fixedly connected to the middle of the cylinder 301. The torsion spring 310 is located inside the outer casing 309. The end of the inlet hose 215 away from the ventilation pipe 211 is fixedly connected to the inside of the air inlet branch pipe 313. The end of the connecting hose 213 away from the air inlet head 212 is fixedly connected to the top of the cylinder 301. Position bar 305 is slidably connected to the inner side of rotating sleeve 306. One end of return spring 308 is fixedly connected to the bottom of rotating sleeve 306, and the other end of return spring 308 is fixedly connected to the top of fixed ring 307. One end of torsion spring 310 is fixedly connected to the inside of outer sleeve 309, and the other end of torsion spring 310 is fixedly connected to the outside of rotating sleeve 306. The top of rotating sleeve 306 is rotatably connected to the inside of bottom end of cylinder 301, and rotating sleeve 306 is rotatably connected to bottom of cylinder 301. When switching the air path, press the cylinder 301 downwards, which will cause the rotating sleeve 306, torsion spring 310, outer sleeve 309, and locking ear 311 to move downwards. The rotating sleeve 306 compresses the return spring 308, and the baffle 302 will move above the air inlet branch pipe 313. At this time, the gas side in the air inlet branch pipe 313 will move to the space above the baffle 302, so the gas will enter the interior of the moving pipe 303 through the vent 304, and then enter the interior of the inflation protection mechanism 4 through the moving pipe 303. When the locking ear 311 moves to the bottom of the locking frame 312, rotate the cylinder 301, which will then cause the outer sleeve 309 and locking ear 311 to rotate. Continue to push the cylinder 301 downwards. When the locking ear 311 moves to the bottom of the locking frame 312, release the cylinder 301. At this time, the reaction force of the torsion spring 310 will... The lower part of the cylinder 301 can drive the outer sleeve 309 and the locking ear 311 to rotate in opposite directions, so that the locking ear 311 is hooked on the locking frame 312. At this time, the air entering the cylinder 301 will enter the interior of the inflation protection mechanism 4 through the moving pipe 303. When it is necessary to introduce gas into the interior of the fan control device 1, simply rotate the cylinder 301. The cylinder 301 drives the outer sleeve 309 and the locking ear 311 to rotate, so that the locking ear 311 rotates out of the top of the locking frame 312. At this time, under the action of the return spring 308, the rotating sleeve 306 and the cylinder 301 are pushed upward, so that the wind deflector 302 is located below the air inlet branch pipe 313. Then, the gas will not enter the interior of the moving pipe 303 through the vent 304, but will enter the interior of the air inlet head 212 through the connecting hose 213, and then the gas will enter the interior of the fan control device 1.

[0024] The inflatable protection mechanism 4 includes a housing 401, which provides an installation position and ventilation conditions. A fixing frame 402 is fixedly connected inside the housing 401, providing the installation position. A movable column 403 is slidably connected inside the fixing frame 402. A baffle plate 404 is fixedly connected to one end of the movable column 403, allowing the baffle plate 404 to be installed. A push spring 405 is sleeved on the outside of the movable column 403, increasing the stability of the push spring 405 during compression or release. A connecting pipe 407 is fixedly connected to one end of the housing 401, providing ventilation. The baffle plate 404 can block the side of the housing 401 closest to the connecting pipe 407. After inflation is complete, the protective gas... When the gas in the bladder 408 is discharged through the housing 401 toward the connecting pipe 407, it can be blocked by the baffle plate 404. The outside of the connecting pipe 407 is fixedly connected to the outside of the fan control device 1. The protective airbag 408 is fixedly connected to the outside of the fan control device 1. One end of the housing 401 is fixedly connected to the outside of the protective airbag 408. The top of the connecting pipe 407 is fixedly connected to the bottom of the moving pipe 303. One end of the push spring 405 is fixedly connected to one side wall of the fixed frame 402. The other end of the push spring 405 is fixedly connected to the end of the baffle plate 404 away from the connecting pipe 407. The end of the movable column 403 away from the baffle plate 404 is fixedly connected to the limit plate 406. The push spring 405 is set inside the housing 401. When gas enters the interior of housing 401 through connecting pipe 407, it pushes baffle 404 toward protective airbag 408, thereby compressing push spring 405. This allows baffle 404 to enter the thicker part of housing 401, whereupon gas enters the protective airbag 408, inflating it. The flexibility of the protective airbag 408 then protects the fan control device 1. Due to the distribution of electronic components inside the fan control device 1, one side of the fan control device 1 is heavier. The protective airbag 408 is then installed on the heavier side of the fan control device 1. When the fan control device 1 falls, the heavier side faces downwards, thus the inflated protective airbag 408 buffers the vibration force, preventing the vibration force from being transmitted to the electronic components inside the fan control device 1, thereby protecting the fan control device 1.

[0025] Working principle: When the fan control device 1 is activated, the input end of the fan control device 1 generates suction, which is transmitted to the inside of the mounting housing 203 through the air intake pipe 202. The outside air is filtered by the filter element 217 inside the mounting housing 203. The filtered air is transmitted to the inside of the ventilation pipe 211 through the output end of the micro air pump 201, and then transmitted to the inside of the connecting hose 213 through the inlet hose 215 and the air path conversion mechanism 3. The air is then transmitted to the inside of the air intake head 212 through the connecting hose 213. The air intake head 212 transmits the filtered air to the inside of the fan control device 1, thereby cooling the fan control device 1. The air is then discharged through the exhaust dust cover 214, which removes the humid air inside the fan control device 1, thus protecting the electronic components inside the fan control device 1. When replacing the filter element 217, first press the mounting cover 205 downwards, which will move the inner shell 206 downwards and compress the retaining spring 207. At this time, the locking block 210 moves downwards out of the groove in the middle of the locking strip 204. Then rotate the mounting cover 205, which will cause the locking block 210 to rotate. When the locking block 210 rotates to the unconnected position between the two locking strips 204, the mounting cover 205 can be removed from the mounting shell 203. When installing the filter element 217, after placing the new filter element 217 inside the mounting shell 203, remove the locking block on the mounting cover 205. Align the 210 with the unconnected part between the two locking strips 204 and slide it under the locking strips 204. Rotate the mounting cover 205. When the locking block 210 rotates to the groove of the locking strip 204, release the mounting cover 205. Under the reaction force of the clamping spring 207, the inner shell 206 and the mounting cover 205 will move upward, so that the locking block 210 can be hung in the groove of the locking strip 204. At this time, the clamping spring 207 is not fully extended, so it can give the limiting ring 208 and the clamping ring 209 a downward force, so that the clamping ring 209 can press against the filter element 217, thus completing the installation of the filter element 217. When switching the air path, press the cylinder 301 downwards, which will cause the rotating sleeve 306, torsion spring 310, outer sleeve 309, and locking ear 311 to move downwards. The rotating sleeve 306 compresses the return spring 308, and the baffle 302 will move above the air inlet branch pipe 313. At this time, the gas side in the air inlet branch pipe 313 will move to the space above the baffle 302, so the gas will enter the interior of the moving pipe 303 through the vent 304, and then enter the interior of the inflation protection mechanism 4 through the moving pipe 303. When the locking ear 311 moves to the bottom of the locking frame 312, rotate the cylinder 301, which will then cause the outer sleeve 309 and locking ear 311 to rotate. Continue to push the cylinder 301 downwards. When the locking ear 311 moves to the bottom of the locking frame 312, release the cylinder 301. At this time, the reaction force of the torsion spring 310 will... The lower part of the cylinder 301 can drive the outer sleeve 309 and the locking ear 311 to rotate in opposite directions, and make the locking ear 311 hang on the locking frame 312. At this time, the air entering the cylinder 301 will enter the interior of the inflation protection mechanism 4 through the moving pipe 303. When it is necessary to introduce gas into the interior of the fan control device 1, simply rotate the cylinder 301. The cylinder 301 drives the outer sleeve 309 and the locking ear 311 to rotate, and makes the locking ear 311 rotate out of the top of the locking frame 312. At this time, under the action of the return spring 308, the rotating sleeve 306 and the cylinder 301 can be pushed upward, so that the baffle 302 is located below the air inlet branch pipe 313. Then the gas will not enter the interior of the moving pipe 303 through the vent 304, but can enter the interior of the air inlet head 212 through the connecting hose 213, and then can enter the interior of the fan control device 1. When gas enters the interior of housing 401 through connecting pipe 407, it pushes baffle 404 towards protective airbag 408, thereby compressing push spring 405. This allows baffle 404 to enter the thicker part of housing 401, whereupon gas enters the protective airbag 408, inflating it. The flexibility of the protective airbag 408 protects the fan control device 1. Due to the distribution of electronic components inside the fan control device 1, one side is heavier. The protective airbag 408 is installed on the heavier side. When the fan control device 1 falls, the heavier side faces down, thus the inflated protective airbag 408 buffers the vibration force, preventing the vibration force from being transmitted to the electronic components inside the fan control device 1, thus protecting the fan control device 1. A single power unit can achieve the functions of heat dissipation, dehumidification, and dustproof protection. By fully utilizing the power of the power unit, i.e., the micro air pump 201, energy saving is achieved.
