Description

[Technical Field]

[0001] This utility model relates to the field of fans, and specifically to a fan. [Background Technology]

[0002] Chinese utility model CN211573839U discloses a wall-mounted electric fan, which consists of an installation block, a first U-shaped support block, a first rotating shaft, a support limiting block, a second U-shaped support block, and a second rotating shaft. The installation block is connected to the first U-shaped support block to facilitate the adjustment of the fan's vertical angle, and the support limiting block is connected to the second U-shaped support block to facilitate the adjustment of the fan's horizontal angle. Finally, the fan is fixed by rotating the first and second rotating shafts to achieve an overall fixed effect.

[0003] Therefore, taking adjusting the vertical angle of an electric fan as an example, when a user needs to adjust the fan's airflow direction, they need to rotate the first rotating shaft to adjust the airflow direction, and then tighten the first rotating shaft to fix it in the desired position. The rotation adjustment between the support plate and the rotating shaft is prone to wear or loosening. When fixing the airflow direction, a simple mechanical locking structure is used, lacking smooth transition and stable holding ability, thus directly affecting the stability of the airflow direction. Over long-term use, this causes the electric fan to be unable to stably remain in the desired position. The above-mentioned electric fan only solves the problem of inconvenient airflow direction adjustment for wall-mounted electric fans, but it still has shortcomings in terms of the flexibility and stability of adjusting the airflow direction of the main fan body.

[0004] In view of the above-mentioned technical problems, this utility model is proposed in this study. [Utility Model Content]

[0005] The technical problem to be solved by this utility model is to provide a fan, including a fan body, a base, an adjustment mechanism and a damping component.

The vibration damping element is nested between the guide post and the fixing part, and the guide post is movably in contact with the vibration damping element. The vibration damping assembly also includes a positioning pin, which passes through the fixing part, the guide post, and the vibration damping element and is connected to all three. The outer surface of the positioning pin is covered with an elastically deformable vibration damping sleeve.

[0010] As described above, the lateral adjustment assembly includes two first bases that are longitudinally and spaced apart on the base, and the first connecting end is accommodated between the two first bases. The lateral adjustment assembly also includes a lateral swing shaft that longitudinally passes through the two first bases and the first connecting end. The connecting member rotates relative to the base in the horizontal direction with the lateral swing shaft as the rotation axis.

[0011] The damping assembly includes a damping hole formed on the first connecting end and a damping element embedded in the damping hole. The damping element has a connecting hole and is sleeved on the yaw shaft through the connecting hole. The damping element is made of an elastically deformable material. The inner side of the damping hole and the outer side of the damping element are respectively provided with a rib and a groove to restrict the rotation of the damping element relative to the damping hole.

[0012] As described above, the longitudinal adjustment assembly includes two second bases that are laterally and spaced apart on one side of the bottom plate of the fan body, and a longitudinal swing shaft that passes through the two second bases and the second connecting end. The fan body rotates relative to the adjustment mechanism in the vertical direction with the longitudinal swing shaft as the rotation axis. The other side of the bottom plate is connected to the guide column of the vibration damping assembly.

[0013] The damping element located in the longitudinal adjustment assembly is sleeved on the longitudinal swing shaft through the connecting hole, and the longitudinal swing shaft passes through the second connecting end of the damping assembly and the connecting element for rotational engagement.

[0014] As described above, the longitudinal adjustment assembly includes two support arms extending from the second connecting end, the fan body is located between the two support arms, the longitudinal adjustment assembly also includes two longitudinal swing shafts respectively arranged laterally on both sides of the fan body, the vibration damping assembly has two, and the vibration damping assembly is respectively arranged between the side of the fan body and the support arm, the base plate of the vibration damping assembly is rotatably connected to the support arm, and the cover plate is relatively fixedly connected to the side of the fan body;

[0015] The damping element located in the longitudinal adjustment assembly is sleeved on the longitudinal swing shaft through the connecting hole, and the longitudinal swing shaft passes through the damping assembly and rotates with the support arm.

Detailed Implementation Methods

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] like Figure 1-9 As shown, this utility model includes a fan, comprising a fan body 3, a base 1, and an adjustment mechanism 4 for adjusting the airflow direction of the fan body 3. The adjustment mechanism 4 includes a connector 5 located between the base 1 and the fan body 3, and a horizontal adjustment component 41 that can rotate relative to the base 1 in the horizontal direction to adjust the airflow direction of the fan body 3. The adjustment mechanism 4 also includes a vertical adjustment component 42 that can rotate relative to the fan body 3 in the vertical direction to adjust the airflow direction of the fan body 3. One end of the connector 5 is a first connecting end 51, and the other end of the connector 5 is a second connecting end 52. The first connecting end 51 is rotatably connected to the horizontal adjustment component 41, and the second connecting end 52 of the connector 5 is rotatably engaged with the vertical adjustment component 42. Both the horizontal adjustment component 41 and the vertical adjustment component 42 have a damping component 6 for stepless adjustment. The damping component 6 is configured such that the fan body 3 can be steplessly adjusted and positioned in the desired airflow direction by the damping component 6.

[0040] This application employs a stepless adjustment method to achieve precise control of the airflow direction of the fan body 3. The fan body 3 can rotate steplessly in both the horizontal and vertical free-moving dimensions and can be stably locked in any desired airflow direction, thereby improving the flexibility and stability of the fan device's airflow. Users can easily make fine adjustments to the airflow direction according to personal preferences and actual needs, enhancing operational flexibility and effectively avoiding the limitations of traditional fan speed adjustment.

[0041] like Figure 1-9As shown, as a further technical solution of this embodiment, a vibration damping component 7 for reducing the vibration generated by the operation of the fan motor is provided between the fan body 3 and the longitudinal adjustment component 42. One end of the vibration damping component 7 is connected to the fan body 3, and the other end of the vibration damping component 7 is connected to the longitudinal adjustment component 42. The vibration damping assembly 7 includes a base plate 78 connected to the fan body 3, a cover plate 75 connected to the longitudinal adjustment assembly 42, a guide post 71, and a fixing part 74 extending from the base plate 78 toward the cover plate 75. The guide post 71 is located on the cover plate 75 and is sleeved with the fixing part 74. The vibration damping assembly 7 also includes a vibration damping element 73 for reducing the energy generated by vibration. The vibration damping element 73 is nested between the guide post 71 and the fixing part 74, and the guide post 71 is movably in contact with the vibration damping element 73. The vibration damping assembly 7 also includes a positioning pin 76, which passes through the fixing part 74, the guide post 71, and the vibration damping element 73 and is connected to all three. The outer surface of the positioning pin 76 is covered with an elastically deformable vibration damping sleeve.

[0042] One side of the cover plate 75 is connected to the fan body 3, and the other side extends outward to form a guide post 71. The guide post 71 has a hollow interior. Correspondingly, a fixing part 74 extends from one side of the base plate 78 of the longitudinal adjustment assembly 42, and the fixing part 74 and the base plate 78 form an open groove, so that the fixing part 74 and the guide post 71 abut against each other. A vibration damping element 73 is embedded between the fixing part 74 and the guide post 71 to isolate them. The bottom surface of the vibration damping element 73 is movably attached to the bottom surface of the guide post 71, its outer side is attached to the fixing part 74, and its inner side is attached to the guide post 71 to avoid hard contact between the fixing part 74 and the guide post 71. The fixing part 74, the vibration damping element 73, and the guide post 71 are also provided with openings for the positioning pin 76 to pass through. In addition, the positioning pin 76 passes through the fixing part 74, the guide post 71, and the vibration damping element 73 and is connected and cooperates with the three. During use, the vibration energy generated by the fan is concentrated on the guide post 71 and then transmitted to the vibration damping element 73. Since the outer surface of the positioning pin 76 is covered with an elastically deformable vibration damping sleeve, it works together with the vibration damping element 73 on the positioning pin 76 to absorb and disperse the vibration energy.

[0043] like Figure 4 , Figure 8 , Figure 9As shown, the vibration damping assembly 7 further includes a first elastic element 72 sleeved on the outer side of the fixing part 74 and a second elastic element 721 placed inside the guide post 71. One end of the first elastic element 72 abuts against the positioning pin 76 and the other end is connected to the base plate 78. One end of the second elastic element 721 is connected to the cover plate 75 and the other end abuts against the positioning pin 76. When the positioning pin 76 has a tendency to move relative to the guide post 71 due to the force transmitted by the guide post 71, the first elastic element 72 and the second elastic element 721 cooperate to prevent the guide post 71 from moving relative to the vibration damping element 73. This can prevent the fixing part 74, the guide post 71, and the vibration damping element 73 from loosening or falling off, thus preventing the vibration damping assembly 7 from failing. Specifically, the first elastic element 72 and the second elastic element 721 can be springs.

[0044] The vibration damping component 7 in this application effectively absorbs and disperses the vibration energy generated by the rotation of the fan motor and blades, preventing vibration from being transmitted to the damping component 6 and avoiding affecting the stability of the connection between the adjustment mechanism 4, the base 1, and the fan body 3. This prevents vibration from being further transmitted to the adjustment mechanism 4 and even the entire fan, ensuring smooth fan operation and maintaining the fan body's position in the airflow direction. Secondly, by reducing vibration, the noise level caused by vibration is indirectly reduced, avoiding unnecessary noise. In the long term, the vibration damping component 7 can reduce fatigue damage to other internal components of the fan, thereby extending the fan's service life and reducing maintenance costs.

[0045] like Figure 1-9 As shown, to further enhance the aesthetics of the fan, a protective cover 77 is added to the outer contour of the vibration damping component 7 in the fan, which also has practical functions of dustproofing and moisture-proofing. At the same time, for easy installation, the positioning pin 76 passes through the protective cover 77 and connects with the fixing part 74, the guide post 71 and the vibration damping element 73.

[0046] like Figure 1-9As shown, as a further technical solution of this application, the lateral adjustment component 41 includes two first bases 11 arranged longitudinally and spaced apart on the base 1, the first connecting end 51 is accommodated between the two first bases 11, the lateral adjustment component 41 also includes a lateral swing shaft 411 that runs longitudinally through the two first bases 11 and the first connecting end 51, the connecting member 5 rotates relative to the base 1 in the horizontal direction with the lateral swing shaft 411 as the rotation axis; the damping component 6 includes a damping hole 61 opened on the first connecting end 51, and a damping member 62 embedded in the damping hole 61, the damping member 62 is provided with a connecting hole 63, the damping member 62 is sleeved on the lateral swing shaft 411 through the connecting hole 63, the damping member 62 is made of an elastically deformable material, and the inner side of the damping hole 61 and the outer side of the damping member 62 are respectively provided with a protruding rib 64 and a groove 65 to restrict the rotation of the damping member 62 relative to the damping hole 61.

[0047] Specifically, the damping element 62 is made of elastically deformable materials such as silicone or rubber. The damping element 62 is embedded in the damping hole 61 of the first connecting end 51. Both first bases 11 have openings for the horizontal swing shaft 411 to pass through. The damping element 62 has connecting holes 63 at both ends for the horizontal swing shaft 411 to pass through. The horizontal swing shaft 411 passes through both first bases 11 and is interference-fitted with the damping element 62 of the first connecting end 51. The first connecting end 51 can be rotatably connected to the base 1. The friction between the surface of the damping element 62 sleeved on the horizontal swing shaft 411 and the inner wall of the damping hole 61 enables the first connecting end 51 and the base 1 to achieve stepless adjustment and positioning. The structure is stable and reliable, and the service life is longer.

[0048] When adjusting the airflow direction of the fan body 3, a force is applied to the fan body 3, thereby driving the horizontal swing shaft 411 to rotate, which in turn drives the damping component 62 to rotate and engage with the through hole, causing the damping component 62 to deform accordingly. The engagement positions between the groove 65 and the rib 64 are staggered to generate a locking force to achieve damping engagement. The connecting piece 5 cooperates with the damping assembly 6 to accurately adjust the rotation angle of the fan body 3 and position it at the current position, so as to achieve stepless adjustment of the airflow direction of the fan body 3.

[0049] like Figure 1-5As shown, as a further technical solution of this embodiment, the longitudinal adjustment component 42 includes two second bases 21 arranged laterally and spaced apart on one side of the base plate 78 in the fan body 3, and a longitudinal swing shaft 421 that passes laterally through the two second bases 21 and the second connecting end 52. The fan body 3 rotates relative to the adjustment mechanism 4 in the vertical direction with the longitudinal swing shaft 421 as the rotation axis. The other side of the base plate 78 is connected to the guide post 71 of the vibration damping component 7. The damping element 62 located in the longitudinal adjustment component 42 is sleeved on the longitudinal swing shaft 421 through the connecting hole 63, and the longitudinal swing shaft 421 rotates through the damping component 6 and the second connecting end 52 of the connecting member 5. Compared with the prior art of fixing the fan body 3 in the desired position by mechanical locking or releasing, this application has the advantages of simple operation and high adjustment flexibility.

[0050] like Figure 1 , Figure 5 As shown, both ends of the horizontal sway shaft 411 and the two ends of the vertical sway shaft 421 are threaded. The adjusting mechanism 4 also includes knobs (not shown in the figure) located at the ends of the horizontal sway shaft 411 and the vertical sway shaft 421. The threaded parts and the knobs are threadedly engaged, facilitating installation and maintenance. The knobs are threadedly connected to both ends of the horizontal sway shaft 411 and one end of the vertical sway shaft 421, facilitating the installation of the horizontal adjustment assembly 41 and the vertical adjustment assembly 42, preventing them from loosening or falling off. During use, there is no need to adjust the knobs repeatedly, and the structure is stable and reliable.

[0051] When assembling the fan, first connect the connector 5 to the base 1, nest the damping element 62 in the damping hole 61 of the first connecting end 51, and connect the horizontal yaw shaft 411 through the first connecting end 51 and the first base 11 associated with the base 1. Fix the knobs at both ends of the horizontal yaw shaft 411. Next, connect the fan body 3 to the connector 5, nest the damping element 62 in the damping hole 61 of the second connecting end 52, and connect the vertical yaw shaft 421 through the second connecting end 52 and the second base 21 associated with the fan body 3. Then fix the knobs at both ends of the vertical yaw shaft 421. Next, install the vibration damping assembly 7, embed the vibration damping element 73 in the fixing part 74, and close the cover plate 75 so that the bottom surface of the guide post 71 fits against the bottom of the vibration damping element 73. The positioning pin 76 passes through the fixing part 74, the vibration damping element 73, and the guide post 71, thereby connecting the vibration damping assembly 7 to the fan body 3. Finally, the base 1 is used to fix the fan to the desired wall or cabinet location using fasteners, thus completing the fan installation. It should be noted that the fasteners mentioned above are commonly threaded components such as bolts and expansion bolts, which are existing technology.

[0052] like Figure 6-9As shown, as another embodiment of this application, the difference between this embodiment and the previous embodiment lies in that the longitudinal adjustment component 42 includes two support arms 53 extending from the second connecting end 52, the fan body 3 is located between the two support arms 53, the longitudinal adjustment component 42 also includes two longitudinal swing shafts 421 respectively arranged laterally on both sides of the fan body 3, the vibration damping component 7 has two, and the vibration damping components 7 are respectively arranged between the side of the fan body 3 and the support arms 53, the base plate 78 of the vibration damping component 7 is rotatably connected to the support arms 53, and the cover plate 75 is relatively fixedly connected to the side of the fan body 3; the damping element 62 located in the longitudinal adjustment component 42 is sleeved on the longitudinal swing shaft 421 through the connecting hole 63, and the longitudinal swing shaft 421 passes through the damping component 6 and rotates with the support arm 53. This application improves structural stability and load-bearing capacity by using the assembly method of connecting the two support arms 53 to both sides of the fan body 3 respectively.

[0053] like Figure 7 As shown, the horizontal swing shaft 411 has threaded portions at both ends, and the vertical swing shaft 421 has a threaded portion at one end, with the threaded portions and the knob forming a threaded fit.

[0054] When installing the fan in this embodiment, since the second connecting end 52 extends to form two support arms 53 that are respectively connected to both sides of the fan body 3, correspondingly, there are two damping components 6 in the longitudinal adjustment assembly 42, and the damping components 6 are respectively arranged between the support arm 53 and the knob. The two swing shafts 421 are distributed in the same axial direction and are respectively located on both sides of the fan body 3, so that the fan body 3 can rotate relative to the adjustment mechanism 4. The cover plate 75 is fixedly connected to the fan body 3 so that the vibration energy generated by the fan body 3 is transmitted to the vibration damping element 73 through the guide post 71 and the vibration energy is absorbed and dispersed in the vibration damping element 73. One end of the swing shaft 421 passes through the support arm 53 and is fixedly connected to the base plate 78 of the vibration damping assembly 7, and the other end is fixedly connected to the knob through the threaded part. The base plate 78 is also provided with holes for fixing the swing shaft 421.

[0055] As a further technical solution of this application, the vibration damping element 73 and the vibration damping sleeve are made of elastically deformable materials, such as silicone, rubber and other deformable materials. They can transmit vibration energy from the guide column 71 to the vibration damping element 73. In the process of absorbing and dispersing vibration energy, the vibration energy is converted into heat energy or other forms of energy, thereby achieving the purpose of reducing vibration energy, protecting the fan as a whole from vibration damage, extending the service life of the fan, and ensuring the stable operation of the fan body 3.

[0056] like Figure 1 , Figure 6As shown, this application also relates to a fan light, including the aforementioned fan and a lamp body 8 disposed on the outer edge of the outer casing of the fan body 3 for illumination. This application combines lighting and fan functions into a single device, making the fan structure more compact and space-efficient. This fan light is suitable for use in workbenches requiring both cooling and lighting. By fixing the fan light to a wall or cabinet, the fan body 3 provides air circulation while also meeting lighting needs. Especially at night or in low-light environments, it achieves the dual functions of lighting and cooling without the need for additional lamps, saving space and cost.

[0057] Furthermore, the lamp body 8 includes a lamp source and a lampshade. The lamp source can be an energy-saving lamp, or it can be replaced with an incandescent lamp or an LED lamp. Energy-saving lamps are more energy-efficient and have a longer lifespan than incandescent lamps, reducing the frequency of lamp source replacement. Moreover, energy-saving lamps are easier to maintain and operate than LED lamps. Additionally, the lampshade covers the lamp source and is fixed to the fan body 3. The lampshade blocks the direct, strong light emitted by the lamp source to prevent direct light from shining into the eyes, thereby evenly scattering the light, expanding the illumination range, and reducing glare. At the same time, the lampshade effectively prevents damage and contamination from external objects, extending the lifespan of the lamp source.
