Description

Technical Field

[0001] The present invention relates to the technical field of fans, and in particular to a fan with good heat dissipation effect. Background Art

[0002] In modern industrial production, many types of factories need to install ventilation fans to maintain a good working environment, ensure the health of employees, and improve production efficiency. For example, some industrial manufacturing factories usually generate a large amount of heat and harmful gases, such as welding, spraying, casting and other processes. These factories need an efficient ventilation system to remove the generated heat and harmful gases to ensure the safety and comfort of the working environment. There are also some logistics and warehousing centers that do not generate as much heat and harmful gases as production workshops, but a good ventilation system still helps to regulate the temperature and humidity in the warehouse, protect the stored goods from moisture and deterioration, and at the same time improve the working comfort of the staff. Therefore, many different types of factories need to use fans, but there are also some problems when using fans.

[0003] Publication No. CN216048152U discloses a ventilation device applied to intelligent buildings, including a ventilation duct and a fan installed inside the ventilation duct. A driving component is arranged on the top surface of the ventilation duct, the driving component drives the driven component to move, the driven component is sleeved outside the rotating shaft, a lead screw is arranged at the end of the rotating shaft, bearing seats are arranged at the ends of the lead screw and the rotating shaft, the lead screw penetrates through the lifting cleaning plate, and a collecting component is arranged on the bottom plate of the ventilation duct.

[0004] The above-mentioned prior art proposes that dust and other sundries attached to the filter screen seriously affect the ventilation quality, are not easy to clean, and affect the ventilation effect. It should be added that during the use of existing fans, in addition to the filter screen being prone to dust accumulation, the fan blades inside the fan are also very prone to dust accumulation. The main reason is that the fan blades rotate at high speed and rub against the air, generating static electricity during this process. The static charge can attract dust particles in the surrounding environment. Therefore, the fan blades also need to be cleaned regularly, otherwise the ventilation and heat dissipation effects will be affected. After existing fans are used for a period of time, in addition to cleaning the filter screen, the fan blades also need to be cleaned, and since the fan blades are located inside the housing, it is more troublesome to clean. Summary of the Invention

[0005] In view of this, the object of the present invention is to provide a fan with good heat dissipation effect. The technical problem to be solved is that in the process of using the existing fan, in addition to the fact that dust is easily accumulated on the filter net, dust is also very easily accumulated on the fan blades inside the fan. Mainly because the fan blades rotate at high speed and rub against the air, static electricity will be generated during this process. The static charge can attract dust particles in the surrounding environment. Therefore, the fan blades also need to be cleaned regularly, otherwise the ventilation and heat dissipation effect will be affected. After the existing fan has been used for a period of time, in addition to cleaning the filter net, the fan blades also need to be cleaned. And since the fan blades are located inside the housing, it is more troublesome to clean them.

[0006] To achieve the above technical object, the technical solution adopted by the present invention is as follows.

[0007] The present invention provides a fan with good heat dissipation effect:

[0008] It includes a filtering unit and a cleaning unit. The filtering unit includes a housing. Both ends of the housing are designed to be open. A baffle is fixed at the opening on one side of the housing. A plurality of protective fences are fixed at the opening on the other side of the housing. An air inlet and a storage groove are formed in the baffle. The air inlet and the storage groove are communicated, and the air inlet is communicated with the outside. The storage groove is communicated with the inside of the housing. A rectangular frame is arranged in the storage groove. A filter net is fixed in the rectangular frame. The cleaning unit includes a first motor. A mounting seat is fixed on the inner wall of the bottom of the housing. The first motor is installed on the mounting seat. A rotating shaft is fixed at the output end of the first motor. A plurality of fan blades are fixed on the outer side of the end of the rotating shaft far away from the first motor. A rectangular plate is arranged in the housing. A plurality of plastic brushes are fixed on the rectangular plate. A driving component for driving the rectangular plate to rotate is arranged in the housing. When the driving component rotates the rectangular plate to a vertical state, the plastic brushes are in contact with the fan blades. When the fan blades rotate, they rub against the plastic brushes to clean the dust on the fan blades. A dust falling groove is formed at the bottom of the housing. A sealing plate capable of sealing the dust falling groove is arranged in the housing. The sealing plate is located below the rectangular plate. It should be noted that after the fan has been used for a period of time, a lot of dust will adhere to both the filter net and the fan blades. Therefore, it is necessary to regularly clean the dust on the filter net and the fan blades to ensure that the fan maintains a good ventilation effect, so as to better dissipate heat from the factory building. Especially for some industrial manufacturing factories, a large amount of heat and harmful gases are usually generated, such as welding, spraying, casting and other processes. It is even more necessary to make the fan maintain a good ventilation state to take away the heat and harmful gases in the factory building.

[0009] As a preferred solution of the fan with good heat dissipation effect described in the present invention, the driving assembly includes a first rotating rod fixed inside the rectangular plate. Both ends of the first rotating rod are rotatably connected to the inner walls on both sides of the housing. A notch is formed on one side of the rectangular plate. A first gear is fixed on the outer side of the first rotating rod, and the first gear is located inside the notch. A first toothed plate is fixed on the sealing plate, and the first toothed plate meshes with the first gear.

[0010] As a preferred solution of the fan with good heat dissipation effect described in the present invention, a connecting plate is fixed on one side of the sealing plate. A vertical plate is fixed on the connecting plate. A disc is fixed on the top of the vertical plate. A cylinder is rotatably connected inside the disc. A first end face toothed ring is fixed on one side of the cylinder. An annular plate is fixed on the outer side of the rotating shaft. A second end face toothed ring is fixed on the side of the annular plate close to the first end face toothed ring. The first end face toothed ring meshes with the second end face toothed ring.

[0011] As a preferred solution of the fan with good heat dissipation effect described in the present invention, a second pulley is fixed on the side of the cylinder away from the first end face toothed ring. A second rotating rod is rotatably connected inside the vertical plate. A first pulley is fixed on the outer side of the second rotating rod. The first pulley and the second pulley are driven by a belt. The axes of the second pulley, the cylinder, the first end face toothed ring, the rotating shaft, the second end face toothed ring, and the annular plate coincide. The diameters of the cylinder, the first end face toothed ring, and the second pulley are all larger than the diameter of the rotating shaft.

[0012] As a preferred solution of the fan with good heat dissipation effect described in the present invention, a through groove is formed in the mounting seat. The connecting plate and the second rotating rod both penetrate through the through groove. A stabilizing plate is fixed on the bottom of the housing. A cylindrical cylinder is rotatably connected inside the stabilizing plate. One end of the second rotating rod extends into the cylindrical cylinder and slides inside the cylindrical cylinder.

[0013] As a preferred solution of the fan with good heat dissipation effect described in the present invention, a plurality of travel grooves are formed at equal intervals along the radial direction on the outer side of the cylindrical cylinder. A plurality of guide blocks are fixed at equal intervals along the radial direction on the outer side of the end of the second rotating rod extending into the cylindrical cylinder. The plurality of guide blocks are respectively slidably fitted in the corresponding travel grooves.

[0014] As a preferred solution of the fan with good heat dissipation effect described in the present invention, guide rods are jointly fixed on the inner walls on both sides of the storage groove. The guide rods penetrate through the rectangular frame. The rectangular frame is slidably fitted outside the guide rods. A spring is sleeved on the outer side of the guide rods. One end of the spring abuts against the inner wall of the storage groove, and the other end of the spring abuts against the rectangular frame.

[0015] As a preferred embodiment of the fan with good heat dissipation effect described in the present invention, wherein: a second toothed plate is fixed to the bottom of the rectangular frame, and an incomplete gear is fixed to one end of the cylindrical barrel away from the second rotating rod, and the incomplete gear meshes with the second toothed plate.

[0016] As a preferred embodiment of the fan with good heat dissipation effect described in the present invention, wherein: a U-shaped seat is fixed to the inner wall of the bottom of the housing, a third toothed plate is arranged in the U-shaped seat, one end of the third toothed plate is hinged with a connecting rod, the other end of the connecting rod away from the third toothed plate is hinged with a connecting plate, a second motor is installed on the top of the U-shaped seat, a rotating shaft is rotatably connected in the U-shaped seat, one end of the rotating shaft is fixed to the output end of the second motor, and a second gear is fixed to the other end of the rotating shaft, and the second gear meshes with the third toothed plate. It should be noted that both the first motor and the second motor are conventional devices well-known to those skilled in the art purchased on the market, and the model can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structures and functions. Their setting methods, installation methods, and electrical connection methods can be debugged and operated by those skilled in the art as long as they follow the requirements of their user manuals, and will not be elaborated here. Moreover, both the first motor and the second motor are provided with matching control switches, and the installation positions of the control switches are selected according to actual use requirements for the convenience of operation and control by the operator.

[0017] As a preferred embodiment of the fan with good heat dissipation effect described in the present invention, wherein: a limiting groove is formed on one side of the third toothed plate, a limiting plate is fixed to the inner wall of one side of the U-shaped seat, the limiting plate is slidably fitted in the limiting groove, a guiding shaft is fixed in the limiting groove, the guiding shaft penetrates through the limiting plate, and the limiting plate is slidably fitted outside the guiding shaft. It should be noted that due to the arrangement of the limiting plate, the limiting groove, and the guiding shaft, when the second gear rotates, the third toothed plate can move along the inner wall of one side of the U-shaped seat, that is, the limiting plate, the limiting groove, and the guiding shaft restrict the moving path of the third toothed plate.

[0018] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0019] 1: Start the second motor to drive the rotating shaft and the second gear to rotate. When the second gear rotates, it drives the third toothed plate to move. When the third toothed plate moves, it drives the connecting rod to rotate. When the connecting rod rotates, it drives the connecting plate and the sealing plate to move. When the sealing plate moves, it drives the first toothed plate to move. When the first toothed plate moves, it drives the first gear to rotate. When the first gear rotates, it drives the first rotating rod and the rectangular plate to rotate, so that the rectangular plate rotates from the horizontal state to the vertical state. Start the first motor to drive the rotating shaft and the fan blade to rotate. At this time, the plastic brush is in contact with the fan blade. That is, when the fan blade rotates, it rubs against the plastic brush, so that the plastic brush sweeps the dust on the fan blade.

[0020] 2: When the sealing plate moves, it no longer seals the dust falling groove, that is, the dust falling groove is exposed. That is, when the plastic brush sweeps the dust on the fan blade, the swept dust will fall from the dust falling groove to the outside.

[0021] 3: When the connecting plate moves, it drives the vertical plate and the disc to move. When the disc moves, it drives the first end face gear ring to move. When the first end face gear ring meshes with the second end face gear ring, when the rotating shaft rotates, it drives the annular plate and the second end face gear ring to rotate. When the second end face gear ring rotates, it drives the first end face gear ring, the cylinder body and the second pulley to rotate. When the second pulley rotates, it drives the first pulley to rotate through the belt. When the first pulley rotates, it drives the second rotating rod and the cylindrical barrel to rotate. When the cylindrical barrel rotates, it drives the incomplete gear to rotate. When the incomplete gear rotates to mesh with the second toothed plate, it drives the second toothed plate to move. When the second toothed plate moves, it drives the rectangular frame and the filter screen to move. When the filter screen moves, it compresses the spring. When the incomplete gear rotates to no longer mesh with the second toothed plate, at this time, under the resilience of the spring, it drives the rectangular frame and the filter screen to move in the reverse direction, so that the rectangular frame and the filter screen vibrate, which is beneficial to the dust on the filter screen to fall off.

[0035] Refer to Figures 1-7 :

[0036] For an embodiment of the present invention, a blower with good heat dissipation effect is provided, which includes a filtering unit 100 and a cleaning unit 200. The filtering unit 100 includes a housing 101. Both ends of the housing 101 are designed to be open. A baffle 102 is fixed at the opening on one side of the housing 101. A plurality of protective fences 109 are fixed at the opening on the other side of the housing 101. An air inlet 103 and a storage groove 104 are formed in the baffle 102. The air inlet 103 is communicated with the storage groove 104, and the air inlet 103 is communicated with the outside, and the storage groove 104 is communicated with the inside of the housing 101. A rectangular frame 105 is arranged in the storage groove 104, and a filter screen 106 is fixed in the rectangular frame 105. The cleaning unit 200 includes a first motor 201. A mounting seat 204 is fixed on the inner wall of the bottom of the housing 101. The first motor 201 is installed on the mounting seat 204. A rotating shaft 202 is fixed at the output end of the first motor 201. A plurality of fan blades 203 are fixed on the outer side of the end of the rotating shaft 202 away from the first motor 201. A rectangular plate 205 is arranged in the housing 101. A plurality of plastic brushes 206 are fixed on the rectangular plate 205. A driving component for driving the rectangular plate 205 to rotate is arranged in the housing 101. When the driving component rotates the rectangular plate 205 to the vertical state, the plastic brushes 206 are in contact with the fan blades 203. When the fan blades 203 rotate, they rub against the plastic brushes 206 to clean the dust on the fan blades 203. A dust falling groove 207 is formed at the bottom of the housing 101. A sealing plate 208 capable of sealing the dust falling groove 207 is arranged in the housing 101. The sealing plate 208 is located below the rectangular plate 205.

[0037] Nowadays, many types of factory buildings need to install fans to improve the ventilation of the factory buildings, so as to discharge the heat in the factory buildings and maintain a good working environment. However, after the fans are used for a period of time, a lot of dust will adhere to both the filter screen 106 and the fan blades 203. Therefore, it is necessary to regularly clean the dust on the filter screen 106 and the fan blades 203 to ensure that the fans maintain a good ventilation effect, so that they can better dissipate heat from the factory buildings. Especially for some industrial manufacturing factory buildings, which usually generate a large amount of heat and harmful gases, such as welding, spraying, casting and other processes, it is even more necessary to keep the fans in a good ventilation state to take away the heat and harmful gases in the factory buildings.

[0038] Among them, the driving assembly includes a first rotating rod 210 fixed inside the rectangular plate 205. Both ends of the first rotating rod 210 are rotatably connected to the inner walls on both sides of the outer shell 101. A notch 209 is formed on one side of the rectangular plate 205. A first gear 211 is fixed on the outer side of the first rotating rod 210. The first gear 211 is located in the notch 209. A first toothed plate 212 is fixed on the sealing plate 208. The first toothed plate 212 meshes with the first gear 211. A U-shaped seat 231 is fixed on the bottom inner wall of the outer shell 101. A third toothed plate 235 is arranged inside the U-shaped seat 231. One end of the third toothed plate 235 is hinged to a connecting rod 230. The end of the connecting rod 230 far away from the third toothed plate 235 is hinged to a connecting plate 213. A second motor 232 is installed on the top of the U-shaped seat 231. A rotating shaft 233 is rotatably connected inside the U-shaped seat 231. One end of the rotating shaft 233 is fixed to the output end of the second motor 232. A second gear 234 is fixed on the other end of the rotating shaft 233. The second gear 234 meshes with the third toothed plate 235. A connecting plate 213 is fixed on one side of the sealing plate 208. A vertical plate 214 is fixed on the connecting plate 213.

[0039] When in use, when it is necessary to clean the dust on the fan blade 203, first start the second motor 232 to drive the rotating shaft 233 to rotate. When the rotating shaft 233 rotates, it drives the second gear 234 to rotate. When the second gear 234 rotates, it drives the third toothed plate 235 to move. When the third toothed plate 235 moves, it drives the connecting rod 230 to rotate. When the connecting rod 230 rotates, it drives the connecting plate 213 to move. When the connecting plate 213 moves, it drives the sealing plate 208 to move. When the sealing plate 208 moves, it drives the first toothed plate 212 to move. When the first toothed plate 212 moves, it drives the first gear 211 to rotate. When the first gear 211 rotates, it drives the first rotating rod 210 to rotate. When the first rotating rod 210 rotates, it drives the rectangular plate 205 to rotate, so that the rectangular plate 205 rotates from a horizontal state to a vertical state, and at this time the plastic brush 206 is in contact with the fan blade 203. Then start the first motor 201 to drive the rotating shaft 202 to rotate. When the rotating shaft 202 rotates, it drives the fan blade 203 to rotate. Since the plastic brush 206 is in contact with the fan blade 203 at this time, that is, when the fan blade 203 rotates, it rubs against the plastic brush 206, so that the plastic brush 206 sweeps the dust on the fan blade 203. It should be noted that when the connecting plate 213 moves, it drives the sealing plate 208 to move, and when the sealing plate 208 moves, it no longer seals the dust falling groove 207, so that the dust falling groove 207 is exposed. That is, when the plastic brush 206 sweeps the dust on the fan blade 203, the swept dust is discharged to the outside from the dust falling groove 207.

[0040] Further, a limiting groove 237 is formed on one side of the third toothed plate 235. A limiting plate 236 is fixed on the inner wall of one side of the U-shaped seat 231. The limiting plate 236 is slidably fitted in the limiting groove 237. A guiding shaft 238 is fixed in the limiting groove 237. The guiding shaft 238 penetrates through the limiting plate 236, and the limiting plate 236 is slidably fitted outside the guiding shaft 238.

[0041] It should be noted that due to the arrangement of the limiting plate 236, the limiting groove 237 and the guiding shaft 238, when the second gear 234 rotates, the third toothed plate 235 can move along the inner wall of one side of the U-shaped seat 231, that is, the limiting plate 236, the limiting groove 237 and the guiding shaft 238 restrict the moving path of the third toothed plate 235.

[0042] In addition, a disc 215 is fixed to the top of the vertical plate 214. A cylinder body 216 is rotatably connected inside the disc 215. A first end face gear ring 217 is fixed to one side of the cylinder body 216. An annular plate 218 is fixed to the outside of the rotating shaft 202. A second end face gear ring 219 is fixed to the side of the annular plate 218 close to the first end face gear ring 217. The first end face gear ring 217 and the second end face gear ring 219 are meshed with each other. A second pulley 222 is fixed to the side of the cylinder body 216 away from the first end face gear ring 217. A second rotating rod 220 is rotatably connected inside the vertical plate 214. A first pulley 221 is fixed to the outside of the second rotating rod 220. The first pulley 221 and the second pulley 222 are driven by a belt 239. The axes of the second pulley 222, the cylinder body 216, the first end face gear ring 217, the rotating shaft 202, the second end face gear ring 219, and the annular plate 218 coincide. The diameters of the cylinder body 216, the first end face gear ring 217, and the second pulley 222 are all larger than the diameter of the rotating shaft 202. A through groove 223 is formed in the mounting seat 204. The connecting plate 213 and the second rotating rod 220 both penetrate through the through groove 223. A stabilizing plate 224 is fixed to the bottom of the outer shell 101. A cylindrical cylinder 225 is rotatably connected inside the stabilizing plate 224. One end of the second rotating rod 220 extends into the cylindrical cylinder 225 and slides inside the cylindrical cylinder 225.

[0043] Specifically, a plurality of stroke grooves 226 are formed in the outer side of the cylindrical cylinder 225 at equal intervals along its radial direction. A plurality of guide blocks 227 are fixed to the outer side of one end of the second rotating rod 220 extending into the cylindrical cylinder 225 at equal intervals along its radial direction. The plurality of guide blocks 227 are respectively slidably fitted in the corresponding stroke grooves 226. It should be noted that due to the arrangement of the stroke grooves 226 and the guide blocks 227, when the vertical plate 214 drives the second rotating rod 220 to move, the second rotating rod 220 will move inside the cylindrical cylinder 225. At this time, the guide blocks 227 will move in the stroke grooves 226. Since the guide blocks 227 are stuck in the stroke grooves 226, that is, when the second rotating rod 220 rotates, due to the action of the guide blocks 227 and the stroke grooves 226, the second rotating rod 220 can drive the cylindrical cylinder 225 to rotate accordingly.

[0044] In addition, guide rods 107 are jointly fixed to the inner walls of both sides of the storage groove 104. The guide rods 107 penetrate through the rectangular frame 105. The rectangular frame 105 is slidably fitted outside the guide rods 107. A spring 108 is sleeved on the outside of the guide rods 107. One end of the spring 108 abuts against the inner wall of the storage groove 104, and the other end of the spring 108 abuts against the rectangular frame 105. A second toothed plate 228 is fixed to the bottom of the rectangular frame 105. An incomplete gear 229 is fixed to the end of the cylindrical cylinder 225 away from the second rotating rod 220. The incomplete gear 229 and the second toothed plate 228 are meshed with each other.

[0045] During use, when the second motor 232 is started to drive the rotating shaft 233 to rotate, the rotating shaft 233 drives the second gear 234 to rotate when it rotates. When the second gear 234 rotates, it drives the third toothed plate 235 to move. When the third toothed plate 235 moves, it drives the connecting rod 230 to rotate. When the connecting rod 230 rotates, it drives the connecting plate 213 to move. When the connecting plate 213 moves, it also drives the vertical plate 214 to move. When the vertical plate 214 moves, it drives the disc 215 to move. When the disc 215 moves, it drives the first end face toothed ring 217 to move. When the rectangular plate 205 rotates to the vertical state, the first end face toothed ring 217 and the second end face toothed ring 219 are engaged at this time. When the vertical plate 214 moves, it also drives the second rotating rod 220 to move. When the second rotating rod 220 moves, it drives the guide block 227 to move in the stroke groove 226. At this time, the rotation of the rotating shaft 202 drives the annular plate 218 to rotate. When the annular plate 218 rotates, it drives the second end face toothed ring 219 to rotate. When the second end face toothed ring 219 rotates, it drives the first end face toothed ring 217 to rotate. When the first end face toothed ring 217 rotates, it drives the cylinder body 216 and the second belt pulley 222 to rotate. When the second belt pulley 222 rotates, it drives the first belt pulley 221 to rotate through the belt 239. When the first belt pulley 221 rotates, it drives the second rotating rod 220 to rotate. When the second rotating rod 220 rotates, it drives the cylindrical barrel 225 to rotate. When the cylindrical barrel 225 rotates, it drives the incomplete gear 229 to rotate. When the incomplete gear 229 rotates to engage with the second toothed plate 228, it drives the second toothed plate 228 to move. When the second toothed plate 228 moves, it drives the rectangular frame 105 and the filter screen 106 to move. When the rectangular frame 105 moves, it compresses the spring 108. When the incomplete gear 229 rotates to no longer engage with the second toothed plate 228, at this time, under the resilience of the spring 108, it drives the rectangular frame 105 and the filter screen 106 to move in the reverse direction, so that the rectangular frame 105 and the filter screen 106 vibrate, which is beneficial to the dust on the filter screen 106 to fall off.

[0046] It should be noted that when the fan is in normal use, the rectangular plate 205 is horizontally arranged at this time, and the first end face toothed ring 217 and the second end face toothed ring 219 are in a separated state at this time, and the dust falling groove 207 is sealed by the sealing plate 208 at this time. In addition, the first motor 201 and the second motor 232 in this embodiment are both conventional devices well-known to those skilled in the art purchased on the market, and the model can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structures and functions. Their setting methods, installation methods and electrical connection methods can be debugged and operated by those skilled in the art as long as they are in accordance with the requirements of their user manuals. Therefore, they will not be elaborated here. Both the first motor 201 and the second motor 232 are provided with matching control switches, and the installation positions of the control switches are selected according to actual use requirements, as long as it is convenient for the operator to operate and control.

[0047] The exemplary embodiments of the solution proposed by the present disclosure have been described in detail above with reference to the preferred embodiments. However, those skilled in the art can understand that, without departing from the concept of the present disclosure, various modifications and variations can be made to the above specific embodiments, and various combinations of the technical features and structures proposed by the present disclosure can be made, without exceeding the protection scope of the present disclosure. The protection scope of the present disclosure is determined by the appended claims.
