Description

Technical Field

[0001] The invention relates to a luminous fan, in particular to a luminous logo fan. Background Art

[0002] Fans are one of the most widely used items for users. They are used to provide wind and provide different functions according to different settings. For example, when a fan is set around the user's body, it can provide wind to the body. When a fan is set in an electronic device, it can provide heat dissipation for electronic components in the electronic device.

[0003] However, since the existing fans can only provide the function of wind force and cannot further provide other effects, how to provide a luminous sign fan to produce different effects has become a topic that urgently needs to be studied. Summary of the invention

[0004] The present invention discloses a luminous sign fan, comprising a fan housing, a driving element, a fan body, a magnetic element, a circuit board, a light-emitting element, a light-transmitting sign, a control element and a Hall element. The driving element is arranged in the fan housing. The fan body is pivotally connected to the driving element and has a housing space. The magnetic element has a first magnetic pole and a second magnetic pole, which are arranged in the housing space of the fan body. The circuit board is arranged on the fan housing. The light-emitting element is arranged on the circuit board. The light-transmitting sign is arranged on the surface of the fan body corresponding to the light-emitting light path of the light-emitting element. The control element is arranged on the circuit board and electrically connected to the light-emitting element. The Hall element is electrically connected to the control element and is arranged on the fan housing corresponding to the position of the magnetic element to sense the magnetism of the first magnetic pole and the second magnetic pole of the magnetic element to generate a voltage sensing signal. The voltage sensing signal includes a first voltage signal level and a second voltage signal level, wherein when the fan body rotates to the initial front position of the light-transmitting mark, the Hall element generates a second voltage signal level, and when the control element receives the second voltage signal level, the control element generates a light signal to the light-emitting element to make the light-emitting element emit light; wherein the initial front position corresponds to the initial angular position of the fan body.

[0005] As mentioned above, the present invention senses the rotation angle of the fan body and the light-transmitting mark through the Hall element, and only when the fan body and the light-transmitting mark rotate to the initial front position, the control element will control the light-emitting element to emit light. In other words, when the user is viewing the light-transmitting mark, the light-transmitting mark will be illuminated by the light-emitting element and observed by the user only when the light-transmitting mark rotates to the initial front position, and will not emit light and be noticed by the user at the remaining rotation angles. In this way, when the fan body is rotating, the user will have the effect of fixing the light-transmitting mark due to visual persistence. In addition, the present invention can sense the magnetic pole position of the magnetic element through the Hall element, and then confirm the rotation angle of the light-transmitting mark. When the light-emitting mark fan is about to stop operating, the final stop position of the fan body can be controlled according to the rotation angle of the light-transmitting mark, so that the fan body can be maintained in a position where the light-transmitting mark is facing up when the fan body stops rotating.

[0032] The structural principle and working principle of the present invention are described in detail below in conjunction with the accompanying drawings:

[0033] See also Figures 1A to 1C , which are a stereoscopic view, an exploded view and a side view of the luminous logo fan of the present invention. The luminous logo fan 1 includes a fan housing 11, a driving element 12, a fan body 13, a magnetic element 14, a circuit board B, a light-emitting element 15, a Hall element 16, a light-transmitting logo 17 and a control element 19. The driving element 12 is disposed in the fan housing 11. The fan body 13 is pivotally connected to the driving element 12 and has a accommodating space. The magnetic element 14 has a first magnetic pole and a second magnetic pole, and is disposed in the accommodating space of the fan body 13. The light-emitting element 15 is disposed on the circuit board B, and the circuit board B is disposed on the fan housing 11. The light-transmitting logo 17 corresponds to the light path of the light-emitting element 15 (such as Figure 1CThe control element 19 is disposed on the surface of the fan body 13. The control element 19 is disposed on the circuit board B and is electrically connected to the light-emitting element 15. The Hall element 16 is electrically connected to the control element 19 through the circuit board B, and is disposed on the fan housing 11 corresponding to the position of the magnetic element 14, sensing the magnetism of the first magnetic pole and the second magnetic pole of the magnetic element 14 to generate a voltage sensing signal. The voltage sensing signal includes a first voltage signal level and a second voltage signal level. When the fan body 13 rotates to the initial positive position of the light-transmitting mark 17, the Hall element 16 generates a second voltage signal level, and when the control element 19 receives the second voltage signal level, the control element 19 generates a light-emitting signal to the light-emitting element 15, so that the light-emitting element 15 emits light, wherein the initial positive position corresponds to the initial angle position of the fan body 13, that is, the light-transmitting mark 17 is placed in a positive upward position. In addition, the light-emitting mark fan 1 further includes a stator 18 disposed on the fan housing 11, and the circuit board B is disposed on the stator 18. Furthermore, in the embodiment of the present invention, the driving element 12 is a motor, the magnetic element 14 is a magnet, the light emitting element 15 is a light emitting diode, and the control element 19 is a processor.

[0034] As mentioned above, in the embodiment of the present invention, when the magnetism of the first magnetic pole is an N pole, the magnetism of the second magnetic pole corresponds to an S pole, or when the magnetism of the first magnetic pole is an S pole, the magnetism of the second magnetic pole corresponds to an N pole. Furthermore, when the first voltage signal level is a high voltage level signal, the second voltage signal level corresponds to a low voltage level signal, or, when the first voltage signal level is a low voltage level signal, the second voltage signal level corresponds to a high voltage level signal. In other words, the Hall element 16 can generate a high voltage level signal and a low voltage level signal according to the magnetic pole configuration position of the magnetic element 14, and the control element 19 generates a light-emitting signal to the light-emitting element 15 according to the high voltage level signal or the low voltage level signal, so that the light-emitting element 15 emits light, that is, the present invention is not limited to generating a light-emitting signal that causes the light-emitting element 15 to emit light by a high voltage level signal or a low voltage level signal.

[0035] See also Figure 2A , which is a schematic diagram of the magnetic configuration of the magnetic unit of the magnetic element of the present invention. In the embodiment of the present invention, the magnetic element 14 is annular in shape and is arranged around the position of the Hall element 16. Figure 2AAs shown, in this embodiment, the magnetic element 14 includes a first magnetic unit 141 and a second magnetic unit 142, the first magnetic unit 141 has a first magnetic pole, and the second magnetic unit 142 has a second magnetic pole. The magnetism of the first magnetic unit 141 and the magnetism of the second magnetic unit 142 are sensed by the Hall element 16 to generate a first voltage signal level and a second voltage signal level respectively. After receiving the first voltage signal level and the second voltage signal level, the control element 19 generates a light-emitting signal to the light-emitting element 15 according to the second voltage signal level, so that the light-emitting element 15 emits light. In the embodiment of the present invention, the Hall element 16 is a bipolar Hall switch element.

[0036] like Figure 2B , which is a schematic diagram of another magnetic unit magnetic configuration of the magnetic element of the present invention. In this embodiment, the magnetic element 14 includes two first magnetic units 141 and two second magnetic units 142, the first magnetic unit 141 has a first magnetic pole, the second magnetic unit 142 has a second magnetic pole, the two first magnetic units 141 and the two second magnetic units 142 are staggered in a ring-shaped position, and the magnetism of the two first magnetic units 141 and the magnetism of the two second magnetic units 142 are sensed by the Hall element 16 to generate a first voltage signal level and a second voltage signal level respectively. Figure 2A The embodiment of the present invention is different in that the Hall element 16 senses the magnetism of the two first magnetic units to generate a secondary first voltage signal level, and senses the magnetism of the two second magnetic units to generate a secondary second voltage signal level. After receiving the secondary first voltage signal level and the secondary second voltage signal level, the control element 16 generates a light-emitting signal to the light-emitting element 15 according to the sensing voltage cycle of the second second voltage signal level generated, so that the light-emitting element 15 emits light. In other words, the control element 19 generates a light-emitting signal to the light-emitting element 15 according to the second second voltage signal level in the sensing voltage cycle, so that the light-emitting element 15 emits light. In the embodiment of the present invention, the Hall element 16 is a bipolar Hall switch element.

[0037] See also FIG. 3A to FIG. 3D , Figure 3A and Figure 3B , Figure 3C and Figure 3D To correspond to Figure 2A and Figure 2B Schematic diagram of the voltage signal of the Hall element and the voltage signal of the light-emitting element generated by the magnetic configuration of the magnetic unit. Figure 3A and Figure 3B As shown, according to Figure 2AThe first magnetic unit 141 and the second magnetic unit 142 are arranged in the positions of the first magnetic unit and the second magnetic unit. The voltage sensing signal generated by the Hall element 16 sensing the magnetism of the first magnetic unit 141 and the second magnetic unit 142 is generated in the timing of the first period T1 and the second period T2, wherein the first period T1 corresponds to the generation of the first voltage signal level, and the second period T2 corresponds to the generation of the second voltage signal level. After receiving the first voltage signal level and the second voltage signal level, the control element 19 generates a light signal to the light-emitting element 15 according to the second voltage signal level, so that the light-emitting element 15 emits light. Corresponding to the generation period of the Hall element voltage sensing signal, the light-emitting element 15 can be set to be a light-emitting period in the first period t1, and the second period T2 of the voltage sensing signal can be set to correspond to the second period t2 of the light-emitting element 15, while the second period t2 of the light-emitting element 15 does not emit light. Therefore, when the light-emitting element 15 emits light in the first period t1 and does not emit light in the second period t2, for the user, the effect of visual persistence can produce the effect of the light-transmitting mark 17 being fixed. In addition, when the light-emitting element 15 emits light toward the light-transmitting mark 17, by setting the first period t1 of the light-emitting element 15 to correspond to the light-transmitting mark 17 being placed in a positive upward position, the light-transmitting mark 17 can be fixed and facing upward during the rotation of the fan body 13 through the effect of visual persistence. In addition, in the embodiment of the present invention, the first period t1 of the light-emitting element 15 is less than the second period T2 of the second voltage signal level. In the embodiment of the present invention, the second period T2 can be set to be N times the first period t1, where N is a positive number and depends on the number of magnetic pole pairs of the first magnetic unit 141 and the second magnetic unit 142, such as Figure 2A In the embodiment, the number of magnetic pole pairs is a pair, so N is 1. By setting the second period T2 to be N times the first period t1, the light-emitting element 15 can be controlled to emit light within a certain angle range during the rotation of the fan body 13, and the light-emitting element 15 can be controlled to emit light within a certain angle range, and the light-emitting element 15 can be further controlled to maintain a fixed light emission effect within a certain angle range.

[0038] Similarly, Figure 3B As shown, it corresponds to Figure 2B Schematic diagram of the voltage signal of the Hall element and the voltage signal of the light-emitting element generated by the magnetic configuration of the magnetic unit. Figure 3B and Figure 3D As shown, according to Figure 2BThe two first magnetic units 141 and the two second magnetic units 142 are arranged alternately, and the voltage sensing signal generated by the Hall element 16 when sensing the magnetism of the two first magnetic units 141 and the two second magnetic units 142 is generated in the timing of the first period T1, the third period T3, the second period T2 and the fourth period T4, respectively, wherein the first period T1 and the third period T3 are corresponding to the generation of the first voltage signal level, and the second period T2 and the fourth period T4 are corresponding to the generation of the second voltage signal level. After receiving the two first voltage signal levels and the two second voltage signal levels, the control element 19 generates a light-emitting signal to the light-emitting element 15 according to the first second voltage signal level in the Hall element voltage sensing signal cycle, so that the light-emitting element 15 emits light. Corresponding to the generation cycle of the Hall element voltage sensing signal, the light-emitting element 15 can be set to be a light-emitting period in the first period t1, and the third period T3, the fourth period T4, and the first period T1 of the voltage sensing signal are set to correspond to the second period t2 of the light-emitting element 15, and the second period t2 of the light-emitting element 15 does not emit light. Therefore, when the light-emitting element 15 emits light in the first period t1 and does not emit light in the second period t2, for the user, the effect of visual persistence can produce the effect that the light-transmitting mark 17 is fixed. In addition, when the light-emitting element 15 emits light toward the light-transmitting mark 17, by setting the first period t1 of the light-emitting element 15 to correspond to the light-transmitting mark 17 being placed in a positive upward position, the light-transmitting mark 17 can be fixed and facing upward during the rotation of the fan body 13 through the effect of visual persistence. In addition, in the embodiment of the present invention, the first period t1 of the light-emitting element 15 is less than the second period T2 of the second voltage signal level. In the embodiment of the present invention, the second period T2 can be set to N times the first period t1, where N is a positive number and depends on the number of magnetic pole pairs of the first magnetic unit 141 and the second magnetic unit 142, such as Figure 2B In the embodiment, there are two pairs of magnetic poles, so N is 2. By setting the second period T2 to be N times the first period t1, the light-emitting element 15 can be controlled to emit light within a certain angle range during the rotation of the fan body 13, and the light-emitting element 15 can be controlled to emit light within a certain angle range, and the light-emitting element 15 can be further controlled to maintain a fixed light emission effect within a certain angle range.

[0039] As mentioned above, Figure 2A and Figure 2B In the embodiment, one and two pairs of magnetic pole pairs of the first magnetic unit 141 and the second magnetic unit 142 are respectively set, but in other embodiments, three to four pairs of magnetic pole pairs of the first magnetic unit 141 and the second magnetic unit 142 can be set, that is, N is an integer between 1 and 4, 1≤N≤4.

[0040] Please refer to Figure 1B ,At Figure 1BIn the embodiment, the luminous logo fan 1 further includes an angle sensor 10, which is electrically connected to the control element 19 and the driving element 12, senses the rotation angle of the driving element 12, and calculates the positions of the two first magnetic units and the two second magnetic units according to the rotation angle, and calculates the period of the Hall element voltage sensing signal according to the position, and transmits the calculation result to the control element 19.

[0041] See also FIG. 4A to FIG. 4D , which is a schematic diagram of the light-emitting mark of the present invention being located at different angles on the fan body. In the present invention, the English letter A is taken as an example to illustrate the pattern of the light-transmitting mark, and the effect of the light-transmitting mark 17 being fixed is produced as described above. By setting the angle position of 0 degrees as the initial angle position and corresponding to the first period t1 of the light-emitting element 15, the light-emitting element 15 can emit light only when the English letter A rotates to the angle position of 0 degrees, and does not emit light when the English letter A rotates to the angle positions of 90 degrees, 180 degrees and 270 degrees, thereby producing the effect of the English letter A being fixed. In other embodiments of the present invention, if the light-transmitting mark 17 has a pattern or shape that is symmetrical up and down, it can be set to emit light when the light-transmitting mark 17 rotates to the angle positions of 0 degrees and 180 degrees, that is, the light-transmitting mark 17 can emit light twice in each rotation process, and does not emit light at other angle positions, thereby producing the effect of the light-transmitting mark 17 being fixed and facing upward. In addition, in the embodiment of the present invention, the light-transmitting mark 17 is made of a light-transmitting material, or has a pattern of a light-guiding layer, and the light-guiding layer is disposed on the light-transmitting mark 17 by sputtering.

[0042] In summary, the present invention senses the rotation angle of the fan body and the light-transmitting mark through the Hall element, and only when the fan body and the light-transmitting mark rotate to the initial front position, the control element will control the light-emitting element to emit light. In other words, when the user is viewing the light-transmitting mark, the light-transmitting mark will be illuminated by the light-emitting element and observed by the user only when the light-transmitting mark rotates to the initial front position, and will not emit light and be noticed by the user at the remaining rotation angles. In this way, when the fan body is rotating, the user will have the effect of fixing the light-transmitting mark due to visual persistence. In addition, the present invention can sense the magnetic pole position of the magnetic element through the Hall element, and then confirm the rotation angle of the light-transmitting mark. When the light-emitting mark fan is about to stop operating, the final stop position of the fan body can be controlled according to the rotation angle of the light-transmitting mark, so that the fan body can be maintained in a position where the light-transmitting mark is facing up when the fan body stops rotating.

[0043] Of course, the present invention may have many other embodiments.
