Description

Technical Field

[0001] This utility model relates to the field of fan technology, specifically an omnidirectional adjustable suspended fan. Background Technology

[0002] Suspended fans are devices that use the principle of air convection or mechanical power to achieve ventilation and cooling. They adopt a dual-head or quad-head design and use a high-voltage generator to generate positive and negative ion airflow to eliminate static electricity. They are suitable for high-cleanliness workshops such as electronics and medical equipment. Their multi-outlet structure takes into account both space utilization and ease of operation, supports independent air volume adjustment, and is equipped with an ionization indicator and grounding protection device.

[0003] Patent CN220087545U discloses a suspended ion fan, relating to the field of ion fan technology. Two insulating plastic plates are provided: one on one side of the fan housing, and the other sealingly dividing the fan housing into two spaces of different sizes. A fan is positioned between the two insulating plastic plates, and a negative and positive aluminum rod are mounted on the fan. The ends of the negative and positive aluminum rods are fixed to the two insulating plastic plates. A circuit board electrically connected to the fan is located inside the fan housing, and the circuit board is placed within the small space isolated by the insulating plastic plates. The fan and control circuit are separated, ensuring the circuit board is in a dry and uncontaminated working environment. Furthermore, the use of aluminum rods and ion needles as electrode structures provides oxidation resistance, corrosion resistance, and resistance to short circuits, making it more suitable for production lines in acidic or alkaline corrosive environments. This ensures effective static elimination of the product and also improves its lifespan and safety.

[0004] The above-mentioned device has certain shortcomings in its use: the device suspends and fixes the fan casing by means of a suspension bracket, which fixes the position of the fan installed inside the fan casing. When it is necessary to blow air in other directions, it cannot be achieved, thus limiting the functionality of the entire device.

[0005] Therefore, this utility model provides an omnidirectional adjustable suspended fan to solve the above problems. Utility Model Content

[0006] To address the shortcomings of existing technologies, this invention provides an omnidirectional adjustable suspended fan, which solves the aforementioned problems.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an omnidirectional adjustable suspended fan, including a hanging plate and a suspension bracket fixed on the left and right sides of the hanging plate. A steering component is installed on the top wall of the hanging plate. A steering frame is fixedly installed on the bottom end of the steering component through the hanging plate via a bearing. Brackets are installed on both sides of the bottom wall of the steering frame. An adjustment component is installed between the brackets. The fan body is installed on the inner side wall of the adjustment component.

[0008] The adjustment assembly includes a drive shaft rotatably mounted between two brackets. Both ends of the drive shaft are fixedly mounted with drive sprockets through the corresponding brackets via bearings. Drive rods are fixedly mounted on the outer side walls of the fan body. The ends of the two drive rods away from the fan body are fixedly mounted with drive sprockets through the corresponding brackets via bearings. Both drive sprockets are connected to the corresponding drive sprockets via drive chains.

[0009] A drive motor is fixedly installed on the side wall of the bracket on the left side. The drive shaft of the drive motor passes through the bracket through a bearing and is fixedly installed with a transmission gear one. A transmission gear two that meshes with the transmission gear one is fixedly installed on the outer wall of the transmission shaft.

[0010] A circular groove is provided between the two supports and at the position corresponding to the transmission rod. Several rollers are rolled on the inner wall of each of the two circular grooves. Rollers are rotatably mounted on each of the rollers. The rollers are fixedly connected to the outer wall of the fan body.

[0011] By adjusting the settings of the components, the fan body can be tilted up and down during operation, thus meeting diverse usage needs.

[0012] Furthermore, the steering assembly includes a limiting frame fixedly installed at the rear of the top wall of the suspended plate, with a limiting groove formed on the outer wall of the limiting frame and a limiting rod fixedly installed on the inner wall of the limiting groove.

[0013] Through the above technical solution, the limiting groove opened on the limiting frame and the limiting rod installed inside it mainly serve to limit the position of the limiting slider when it moves.

[0014] Furthermore, a limiting slider is slidably installed on the outer wall of the limiting rod, the outer wall of the limiting slider is slidably connected to the inner wall of the limiting groove, and a transmission rack is fixedly installed on the front wall of the limiting slider.

[0015] Through the above technical solution, when the transmission rack moves, it drives the limiting slider to slide along the limiting rod in the inner wall of the limiting groove to achieve position limitation.

[0016] Furthermore, an adjusting push rod is fixedly installed on the right side of the top wall of the suspended platform, and the movable end of the adjusting push rod is fixedly connected to the right side wall of the transmission rack.

[0017] Through the above technical solution, the movable end of the adjusting push rod can drive the transmission rack to move during extension and retraction, thereby driving the linkage gear meshing with it to rotate.

[0018] Furthermore, a reinforcing shaft is rotatably mounted on the top wall of the suspended platform, and a linkage gear that meshes with the middle of the transmission rack is fixedly mounted on the top of the reinforcing shaft.

[0019] With the above technical solution, as the transmission rack drives the linkage gear to rotate, it will synchronously drive the reinforcing shaft to rotate and the bogie to rotate.

[0020] Furthermore, the bottom end of the shaft is reinforced by a bearing that passes through the suspension plate and is fixedly connected to the top wall of the bogie.

[0021] The above technical solutions enhance the left and right steering adjustment of the shaft-driven bogie, support, adjustment components, and fan body.

[0022] Furthermore, the same protective cover is installed on the top wall of the suspended platform, corresponding to the positions of the limit frame and the adjusting push rod.

[0023] The protective cover, as described above, is primarily designed to protect the external structure of the steering assembly.

Detailed Implementation

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] Example 1:

[0038] Please see Figures 1-7 An omnidirectional adjustable suspended fan includes a hanging plate 1 and a suspension bracket 2 fixed on the left and right sides of the hanging plate 1. A steering component 3 is installed on the top wall of the hanging plate 1. A steering frame 4 is fixedly installed on the bottom end of the steering component 3 through the hanging plate 1 via a bearing. Supports 5 are installed on both sides of the bottom wall of the steering frame 4. An adjustment component 7 is installed between the supports 5. The fan body 6 is installed on the inner side wall of the adjustment component 7.

[0039] The adjustment assembly 7 includes a drive shaft 71 rotatably mounted between two brackets 5. Both ends of the drive shaft 71 are fixedly mounted with drive sprockets 72 through bearings through the corresponding brackets 5. Drive rods 73 are fixedly mounted on the outer side walls of the fan body 6. The ends of the two drive rods 73 away from the fan body 6 are fixedly mounted with drive sprockets 74 through bearings through the corresponding brackets 5. Both drive sprockets 74 are connected to the corresponding drive sprockets 72 through a drive chain 75.

[0040] A drive motor 78 is fixedly installed on the side wall of the bracket 5 on the left side. The power shaft of the drive motor 78 passes through the bracket 5 through the bearing and is fixedly installed with a transmission gear 77. A transmission gear 76 that meshes with the transmission gear 77 is fixedly installed on the outer wall of the transmission shaft 71.

[0041] A circular groove 711 is provided between the two supports 5 and at the position corresponding to the transmission rod 73. Several rollers 79 are rolled on the inner wall of the two circular grooves 711. Rollers 710 are rotatably installed on the rollers 79. The rollers 710 are fixedly connected to the outer wall of the fan body 6.

[0042] In this embodiment of the utility model, the purpose of this setting is that the main function of the adjustment component 7 is to adjust the up and down rotation of the fan body 6. The transmission rod 73 is driven to rotate synchronously through the transmission sprocket 1 72 and the transmission sprocket 2 74. The transmission rod 73 drives the fan body 6 to perform adjustment and rotation. When the fan body 6 rotates, it will drive the roller 79 and the roller shaft 710 to rotate in the inner wall of the circular groove 711 to optimize the overall stability during operation.

[0043] Example 2:

[0044] Please see Figures 1-7 This embodiment provides a technical solution based on embodiment one: the steering assembly 3 includes a limiting frame 34 fixedly installed at the rear of the top wall of the hanging plate 1. A limiting groove 35 is opened on the outer wall of the limiting frame 34. A limiting rod 36 is fixedly installed on the inner wall of the limiting groove 35. A limiting slider 37 is slidably installed on the outer wall of the limiting rod 36. The outer wall of the limiting slider 37 is slidably connected to the inner wall of the limiting groove 35. A transmission rack 33 is fixedly installed on the front wall of the limiting slider 37. An adjusting push rod 31 is fixedly installed on the right side of the top wall of the hanging plate 1. The movable end of the adjusting push rod 31 is fixedly connected to the right side wall of the transmission rack 33. A reinforcing shaft 39 is rotatably installed on the top wall of the hanging plate 1. A linkage gear 38 that meshes with the middle of the transmission rack 33 is fixedly installed at the top of the reinforcing shaft 39. The bottom end of the reinforcing shaft 39 passes through the hanging plate 1 through a bearing and is fixedly connected to the top wall of the bogie 4. The same protective cover 32 is provided on the top wall of the hanging plate 1 at the positions corresponding to the limiting frame 34 and the adjusting push rod 31.

[0045] In this embodiment of the utility model, the purpose of this arrangement is that the steering component 3 is mainly used to adjust the left and right steering of the bogie 4, the bracket 5, the adjustment component 7 and the fan body 6, and in conjunction with the adjustment of the adjustment component 7, the entire device has the function of omnidirectional adjustment.

[0046] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0047] The working principle of this device is as follows: During operation, the controller and power supply are electrically connected to adjust the push rod 31, drive motor 78 and fan body 6. At the same time, the suspension bracket 2 is fixedly installed in the corresponding installation position by fasteners. The suspension bracket 2 and the hanging plate 1 complete the suspension installation of the entire device.

[0048] When the fan body 6 needs to be adjusted for direction during operation, the extension or retraction of the movable end of the adjustment push rod 31 drives the transmission rack 33 to move laterally to the left or right. This causes the transmission rack 33 to drive the limit slider 37 to slide along the outer wall of the limit rod 36 and in the inner wall of the limit groove 35 of the limit frame 34. As the transmission rack 33 moves laterally, the linkage gear 38 and the reinforcing shaft 39 meshing with it begin to rotate. When the reinforcing shaft 39 rotates, it drives the bogie 4, the bracket 5, the adjustment assembly 7 and the fan body 6 to start to turn, thereby completing the adjustment of the direction of rotation of the fan body 6. The specific direction of rotation adjustment is operated according to actual needs.

[0049] When the fan body 6 needs to be tilted up and down, the drive motor 78 drives the transmission gear 77 to rotate the transmission gear 76 meshing with it. When the transmission gear 76 rotates, it drives the transmission shaft 71 and the transmission sprocket 72 to rotate. The transmission sprocket 72 drives the transmission sprocket 74 and the transmission rod 73 to rotate through the transmission chain 75. When the transmission rod 73 rotates between the brackets 5, it drives the fan body 6 to tilt up and down. The specific adjustment direction is operated according to the actual needs. When the fan body 6 is tilted up and down, it drives the roller 710 and the roller 79 to roll in the inner wall of the circular groove 711. The setting of the roller 79 and the roller 710 can increase the overall stability of the fan body 6 during the turning process.
