Description

Technical Field

[0001] The invention relates to a fan, in particular to a fan capable of producing a glare visual effect. Background Art

[0002] In addition to the existing heat dissipation function, in order to increase the aesthetics of the cooling fan during operation, light-emitting diodes are more widely used and combined in the cooling fan, so that the cooling fan produces a dazzling visual effect while running, thereby improving the added value of the product and increasing consumers' willingness to buy.

[0003] The existing heat dissipation fan may have a fan frame and a driving circuit board, the fan frame may have a ring wall, the driving circuit board is arranged in the ring wall, the driving circuit board may have multiple light-emitting components, a fan frame is rotatably arranged on the fan frame, and the fan wheel may have multiple transparent blades, and the multiple transparent blades are axially aligned with the multiple light-emitting components. Thereby, during the rotation of the fan wheel, the multiple transparent blades can cooperate with the multiple light-emitting components to produce a visual effect of light projection, so as to increase the variability of the glare of the heat dissipation fan. An embodiment similar to the existing heat dissipation fan has been disclosed in the patent case of Taiwan Announcement No. M240610 "DC Fan with Glare Effect".

[0004] However, since the plurality of light-emitting components of the conventional cooling fan are arranged within the rotation range of the fan wheel, when the plurality of transparent blades are rotating, the light generated by the plurality of light-emitting components penetrates through the plurality of transparent blades and scatters outward. If the user directly observes the appearance of the cooling fan, the light-emitting range of the plurality of light-emitting components is only in the central part of the cooling fan. Therefore, in view of the ever-changing novelty mentality of consumers, the visual effect of the glare generated by the cooling fan still has room for improvement.

[0005] In view of this, the existing heat dissipation fans still need to be improved. Summary of the invention

[0006] In order to solve the above problems, an object of the present invention is to provide a fan, in which the glare visual effect presented by the light-emitting group can be viewed from around the fan frame.

[0007] Another object of the present invention is to provide a fan which can reduce manufacturing costs.

[0008] Another object of the present invention is to provide a fan that can improve assembly convenience.

[0013] The fan of the present invention comprises: a fan frame having a ring wall; a fan wheel rotatably arranged on the fan frame, and the ring wall is arranged around the fan wheel; a light-emitting group is located on the ring wall; and at least one light-distributing ring is combined with the fan frame, the light-distributing ring has a plane connected to an axial end face of the ring wall, the light-distributing ring has a predetermined thickness extending from the plane toward a direction away from the light-emitting group at a position where the plane is aligned with the light-emitting group, the light generated by the light-emitting group is irradiated on the plane of the light-distributing ring, and glare is generated from at least two sides of the predetermined thickness.

[0014] Therefore, the fan of the present invention utilizes the light-emitting group to be located on the ring wall, the at least one light-distributing ring is combined with the fan frame, and the plane of the light-distributing ring is connected to an axial end face of the ring wall; when the fan wheel rotates, in addition to helping to dissipate heat, the light generated by the light-emitting group can irradiate the plane of the light-distributing ring, and generate glare on at least two sides extending from the predetermined thickness of the light-distributing ring, and the user can watch the glare visual effect presented by the light-emitting group from around the fan frame, thereby not only bringing more business opportunities to the industry, but also combining practicality and aesthetics.

[0015] The ring wall may have an inner wall portion located inside an outer wall portion, and the light-emitting group is located between the inner wall portion and the outer wall portion. Thus, the structure is simple and easy to manufacture, and has the effect of reducing the manufacturing cost.

[0016] The ring wall has a plurality of protrusions connected to the inner wall portion or the outer wall portion respectively, the light-emitting group has a plurality of light-emitting components connected to a belt body, the belt body is vertically arranged between the inner wall portion and the outer wall portion, and the plurality of protrusions laterally limit the belt body. In this way, the plurality of light-emitting components can be arranged at different axial positions on the belt body, so that the height positions of the plurality of light-emitting components can be easily adjusted, so that the plurality of light-emitting components can be closer to the plane of the uniform light ring, which has the effect of ensuring that the light generated by the light-emitting group can be irradiated on the plane of the uniform light ring.

[0017] The ring wall may have a plurality of connecting ribs connecting the inner wall portion and the outer wall portion, the ring wall may have a plurality of latching portions connecting the outer wall portion or the inner wall portion, and the belt body may be limited between the plurality of connecting ribs and the plurality of latching portions. In this way, the light-emitting group can be prevented from axially separating from the fan frame, thereby improving the stability of the combination.

[0018] The fan frame may have at least one first combination portion at each of the corners, and the light averaging ring may have multiple second combination portions, which are respectively combined with the multiple first combination portions. In this way, the light averaging ring can be firmly combined with the fan frame, and has the effect of combining firmly.

[0019] The outer peripheral surface of the light-homogenizing ring may have a groove, each second joint portion may be a cutout extending from the plane to the first groove wall of the groove, and each first joint portion may be clamped against the first groove wall. Thus, the structure is simple and easy to manufacture, and has the effect of reducing the manufacturing cost.

[0020] The light averaging ring may have an outer end surface opposite to the plane, and the outer end surface may be adjacent to an air inlet or an air outlet of the fan frame. In this way, the light generated by the multiple light emitting components can pass through the two light averaging rings and form an outer diffuse emission, which has the effect of presenting different states of glare visual effects.

[0021] The ring wall has an inner wall portion located inside an outer wall portion, the outer end surface adjacent to the inner wall portion may be closer to the axial end surface, the outer end surface adjacent to the outer wall portion may be farther from the axial end surface, and the outer end surface may form an inclined flow-guiding surface. In this way, the outer end surface may be inclined, and the light generated by the multiple light-emitting components may easily pass through the two light rings and scatter out, which has the effect of presenting a multi-directional glare effect.

[0022] The outer peripheral surface of the light-distributing ring may have a groove, the groove may have a first groove wall and a second groove wall opposite to each other, and the light-distributing ring may have a plurality of light-guiding ribs connecting the first groove wall and the second groove wall. In this way, the light generated by the light-emitting group may be scattered from the surroundings of the plurality of light-guiding ribs, thus achieving a multi-directional glare effect.

[0023] The light-emitting group may have a plurality of light-emitting components connected to a belt body, and the end of the light-guiding rib closer to the light-emitting group may be located opposite to the light-emitting component. Thus, the light generated by the light-emitting component may be scattered around the light-guiding rib, thereby presenting a multi-directional glare effect.

[0024] There can be two averaging rings, and the planes of the two averaging rings can be connected to the two axial end faces of the ring wall respectively, and the light generated by the light emitting group irradiates the two averaging rings. In this way, the light emitting group can generate glare in the direction of the air inlet and the air outlet, and has the effect of multi-directional glare effect.

[0025] The light-emitting group may have a plurality of light-emitting components connected to a belt body, and each light-emitting component may emit light in the axial direction of the fan frame. Thus, the light-emitting group may generate multi-directional glare in the axial direction of the fan frame, and has the effect of presenting glare visual effects in different states.

[0026] The light-emitting assembly emitting light toward the air inlet of the fan frame and the light-emitting assembly emitting light toward the air outlet of the fan frame can be arranged at intervals on the belt body. In this way, the light-emitting group can produce a bright, dark, bright, dark visual effect when viewed from around the fan frame.

[0027] The axial positions of the light-emitting components emitting light toward the air inlet on the belt body are the same, the axial positions of the light-emitting components emitting light toward the air outlet on the belt body can be the same, and the axial positions of the light-emitting components emitting light toward the air inlet and the light-emitting components emitting light toward the air outlet can be different. In this way, the light-emitting components can be adjusted to be closer to the air inlet and closer to the air outlet as needed, so that the light transmittance of each light-emitting component is higher, which is convenient to use.

[0028] The fan of the present invention may further include a circuit board and a plurality of illuminants, the circuit board is arranged on a base of the fan frame, the plurality of illuminants are arranged on the circuit board, the fan wheel may have a hub connected to a plurality of blades, the hub and the plurality of blades may be made of light-conducting material, the hub may have an inner shell portion located inside an outer shell portion, a bottom ring of the hub may connect the bottom end of the inner shell portion with the bottom end of the outer shell portion, and the bottom ring and the plurality of illuminants may be axially opposite. In this way, the light generated by the plurality of illuminants may be indirectly projected through the bottom ring and the outer shell portion and through the plurality of blades, and has the effect of producing a rotating glare effect like a halo or different light colors.

[0029] The fan wheel may have a cover connected to the top of the hub. In this way, the light generated by the plurality of illuminants can be guided by the bottom ring to the outer shell or the plurality of fan blades.

[0030] The light-emitting group may include a plurality of light-emitting components, and the plurality of light-emitting components may have at least two or more colors of light. Thus, the plurality of light-emitting components may produce effects of different light colors.

[0031] The light-emitting group may include a plurality of light-emitting components, and the plurality of light-emitting components may be LEDs with three primary colors of RGB. In this way, the plurality of light-emitting components have the effect of generating a combination of a plurality of different colors.

[0032] The predetermined thickness may be less than or equal to the maximum height of the light averaging ring, and the predetermined thickness may be greater than or equal to the minimum height of the light averaging ring. Thus, when the light generated by the light emitting group is irradiated on the plane of the light averaging ring, different visual effects may be generated by virtue of the different predetermined thicknesses of the light averaging ring, thereby providing different glare visual effects.

[0033] The fan of the present invention may further include a plurality of buffers, which may be combined with the fan frame and may be higher than the light balancing ring in the axial direction. In this way, when the fan wheel rotates, the vibration force can be prevented from being transmitted to the outside of the fan, which has the effect of providing a better shock absorption effect.

[0034] The outer peripheral surface of the light-distributing ring may have a groove, the groove may have a first groove wall opposite to the plane, and the light-distributing ring may have a plurality of light-guiding ribs connected to the first groove wall and extending from the first groove wall in a direction away from the light-emitting component. Thus, when the light generated by the light-emitting component is irradiated on the plane of the light-distributing ring, it can be scattered around the light-guiding ribs, thereby having the effect of presenting a multi-directional glare effect.

[0035] The ring wall may have an inner wall portion located inside an outer wall portion, and the light-distributing ring may have a light-guiding protrusion connected to the plane, and the light-guiding protrusion may extend between the inner wall portion and the outer wall portion. In this way, the plurality of light-emitting components may be closer to the light-guiding protrusion, so that the light generated by the light-emitting components may pass through the light-guiding protrusion and be scattered through the predetermined thickness of the light-distributing ring, thereby presenting different glare visual effects.

[0036] The light-guiding protrusion can be a single ring-shaped structure, so that the structure is simple and easy to manufacture, and has the effect of reducing the manufacturing cost. BRIEF DESCRIPTION OF THE DRAWINGS

In addition to improving the smoothness of the guide when the airflow passes through the air inlet 14 and the air outlet 15, the light generated by the multiple light-emitting components 322 can easily pass through the two equilibrating rings 4 and scatter out.

[0117] Please refer to Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the outer circumference of the two light-averaging rings 4 may also have a groove 43 respectively, and the side profile of the two light-averaging rings 4 may be roughly C-shaped. The groove 43 may have a first groove wall 43a and a second groove wall 43b opposite to each other, and the first groove wall 43a is closer to the plane 41 than the second groove wall 43b. The two light-averaging rings 4 may respectively have a plurality of light-guiding ribs 44, and the plurality of light-guiding ribs 44 may connect the first groove wall 43a and the second groove wall 43b.

In this way, when the light generated by the light-emitting group 3 is irradiated on the plane 41 of the averaging ring 4, different visual effects can be produced by virtue of the different predetermined thicknesses T of the averaging ring 4.

[0119] In other embodiments, the light averaging ring 4 may not have the groove 43. For example, the light averaging ring 4 may be as follows: Fig.11 The predetermined thickness T may be between the maximum height H1 and the minimum height H2, or Fig.13 As shown, the entire structure is filled solidly and the outer end surface 42 is parallel to the plane 41 . The predetermined thickness T may be equal to the maximum height H1 and the minimum height H2 of the uniform light ring 4 , which is not limited by the present invention.

[0120] In addition, the light-distributing ring 4 may have a plurality of second combining portions 45, and the plurality of second combining portions 45 may be respectively combined with the plurality of first combining portions 13. The plurality of second combining portions 45 are based on the principle of being able to match and combine with the plurality of first combining portions 13. The present invention does not limit the shape of the plurality of second combining portions 45. In the present embodiment, each second combining portion 45 may be a cutout extending from the plane 41 to the first groove wall 43a of the groove 43. Each first combining portion 13 is clamped against the first groove wall 43a, so that the light-distributing ring 4 can be firmly combined with the fan frame 1.

[0122] Please refer to Figure 5As shown, the ring wall 12 is arranged around the fan wheel 2, the light-emitting group 3 is located between the inner wall portion 12a and the outer wall portion 12b of the ring wall 12, and the light generated by the light-emitting group 3 can be irradiated on the plane 41 of the light-evening ring 4, so that the light generated by the light-emitting group 3 can generate glare from at least two sides extending from the predetermined thickness of the light-evening ring 4, so as to present glare visual effects in different states. At the same time, the multiple light-guiding ribs 44 of the light-evening ring 4, which are closer to the end of the light-emitting group 3, can be located opposite to the light-emitting component 32, so that the light generated by the light-emitting component 32 of the light-emitting group 3 can be scattered out through the surroundings of the light-guiding ribs 44, so as to present a multi-directional glare effect.

[0123] In addition, the plurality of illuminants 6 can be disposed on the circuit board 5 and axially aligned with the bottom ring 213 of the hub 21, and the cover 23 can abut against the top of the hub 21, so that the light generated by the plurality of illuminants 6 can be indirectly projected through the bottom ring 213 and the shell 212, and through the plurality of blades 22. In this way, when the fan wheel 2 rotates, in addition to helping to dissipate heat, the light generated by the plurality of illuminants 6 can produce a rotating glare effect like a halo or different light colors.

[0124] Please refer to Figure 1 , Figure 5 As shown, it is also explained that the fan of the present invention may further include a plurality of buffer members X, which are preferably made of elastic materials such as rubber or silicone. The plurality of buffer members X can be combined with the fan frame 1, for example, by means of screws or gluing. The plurality of buffer members X can be respectively located at the plurality of corners R, and the plurality of buffer members X can be higher than the uniform ring 4 in the axial direction; in this way, when the fan wheel 2 rotates, the plurality of buffer members X can provide a shock-absorbing effect to prevent the vibration force from being transmitted to the outside of the fan.

The plurality of light-guiding ribs 44 of the light-evening ring 4 at one end closer to the light-emitting group 3 can be aligned with the light-emitting component 32. Meanwhile, in the present embodiment, the predetermined thickness T is the junction from the axial alignment of the light-emitting component 32 to the upper edge of the light-guiding rib 44, and extends from the entire plane 41 to the entire thickness of the light-guiding rib 44. Thus, when the light generated by the light-emitting component 32 is irradiated on the plane 41 of the light-evening ring 4, it can be scattered around the light-guiding rib 44 to present a multi-directional glare effect.

[0126] Please refer to Fig.16, Fig.17 , Fig.18 As shown, it is the third embodiment of the motor of the present invention. The two light-equalizing rings 4 can respectively have a light-guiding protrusion 46, and the light-guiding protrusion 46 can be connected to the plane 41 and extend toward the direction of the light-emitting component 32. The end of the light-guiding protrusion 46 closer to the light-emitting group 3 can be located opposite to the light-emitting component 32. The light-guiding protrusion 46 can be a ring shape formed by a plurality of cylinders arranged at intervals, or a single ring. In the present embodiment, the light-guiding protrusion 46 is illustrated as a single ring. The light-guiding protrusion 46 can extend between the inner wall portion 12a and the outer wall portion 12b, so that the plurality of light-emitting components 32 can be closer to the light-guiding protrusion 46, so that the light generated by the light-emitting component 32 can pass through the light-guiding protrusion 46 and be scattered through the predetermined thickness T of the light-equalizing ring 4, so as to present different glare visual effects.
