DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Reference Figure 1 - Figure 7 A LED bulb lamp that is easy to dissipate heat includes a lampshade 1 and a lamp shell 4. The upper end of the lampshade 1 is fixedly connected to a plurality of heat dissipation fins 2. The upper ends of the plurality of heat dissipation fins 2 are commonly fixedly connected to a fixing frame 3. The upper end of the fixing frame 3 is fixedly connected to the lower end of the lamp shell 4.

[0032] The heat dissipation mechanism includes a plurality of through grooves opened on the side walls of a plurality of heat dissipation fins 2, the inner walls of the plurality of through grooves are rotatably connected with metal tubes 5, the side walls of the plurality of metal tubes 5 are fixedly connected with metal plates 6, and the side walls of the plurality of metal plates 6 are respectively fitted with the inner walls of the plurality of through grooves. It should be noted that the two inner walls of the through grooves close to the metal plates 6 are arc-shaped, and the center of the arc coincides with the center of the metal tube 5, so that when the metal tube 5 drives the metal plate 6 to rotate, the through groove will not hinder the rotation of the metal plate 6, and a first annular groove 7 is opened on the inner wall of the fixed frame 3, and a plurality of slide plates 8 that can revolve are slidably connected to the inner wall of the first annular groove 7, and the side walls of the plurality of slide plates 8 close to each other are fixedly connected with a gear ring 9, and the side walls of the plurality of metal tubes 5 all pass through the inner bottom of the fixed frame 3, and the side walls of the plurality of metal tubes 5 located in the fixed frame 3 are fixedly connected with gears 10, and the inner wall of the gear ring 9 is meshed with the side walls of the plurality of gears 10.

[0033] A driving mechanism is provided on the lamp housing 4, and the driving mechanism includes a first one-way bearing 12. A micro motor 11 is fixedly connected to the inner wall of the lamp housing 4 through a connecting plate. The side wall of the movable shaft of the micro motor 11 is fixedly connected to the inner ring side wall of the first one-way bearing 12. A triangular folding rod 13 is fixedly connected to the outer ring side wall of the first one-way bearing 12. The lower ends of the triangular folding rods 13 are fixedly connected to the upper end of the gear ring 9.

[0034] It should be noted that when the micro motor 11 rotates in the forward direction, the inner ring of the first one-way bearing 12 drives its outer ring to rotate, and when the micro motor 11 rotates in the reverse direction, the inner ring of the first one-way bearing 12 does not drive its outer ring to rotate, and a temperature sensor (not shown in the figure) is provided in the lampshade 1. When the temperature sensor senses that the temperature inside the lampshade 1 is high, the micro motor 11 is controlled to rotate forward through an external control mechanism, and its control method is the existing technology.

[0035] Then when the temperature inside the lampshade 1 rises, the micromotor 11 rotates forward, so that the inner ring of the first one-way bearing 12 drives its outer ring to rotate, and the outer ring of the first one-way bearing 12 drives the gear ring 9 to rotate through the triangular folding rod 13, and the gear ring 9 drives the multiple metal tubes 5 to rotate through multiple gears 10, and drives the multiple metal plates 6 to rotate, which can accelerate the air flow in the multiple heat dissipation fins 2, and then increase the heat dissipation effect of the multiple heat dissipation fins 2 on the lampshade 1, avoiding the problem in the prior art that when the lampshade 1 is used for a long time and the heat generated is high, the temperatures of the multiple heat dissipation fins 2 are simultaneously high, and the heat in the lampshade 1 cannot be dissipated in time, thereby affecting its heat dissipation efficiency.

[0036] A fixing ring 14 is fixedly connected to the bottom of the fixing frame 3, a second annular groove 15 is opened at the upper end of the fixing ring 14, the inner wall of the second annular groove 15 is sealed and fixedly connected to the first ring 16, the inner wall of the second annular groove 15 located above the first ring 16 is sealed and slidably connected to the second ring 20, the inner wall of the second annular groove 15 located between the first ring 16 and the second ring 20 is fixedly connected to a plurality of one-way liquid outlet pipes 18 corresponding to the plurality of metal tubes 5 one by one, and the side wall of the one-way liquid outlet pipe 18 is sealed and rotatably connected to the upper part of the inner wall of the corresponding metal tube 5 (such as Figure 3 As shown), a plurality of one-way liquid inlet pipes 19 corresponding to the plurality of metal tubes 5 are fixedly connected to the bottom of the second annular groove 15, and the side wall of the one-way liquid inlet pipe 19 is sealed and rotatably connected to the lower part of the inner wall of the corresponding metal tube 5 (as shown in FIG. Figure 2 As shown), the side wall of the first ring 16 is fixedly connected with two one-way suction pipes 17.

[0037] Coolant is provided in the closed space formed between the lower end of the first ring 16 and the inner wall of the second annular groove 15 , and an elastic ball 33 is fixedly connected to the inner wall of the second annular groove 15 to balance the pressure change in the closed space during the flow of the coolant.

[0038] The one-way liquid outlet pipe 18 only allows the coolant to enter the metal tube 5 from the second annular groove 15 , the one-way liquid inlet pipe 19 only allows the coolant to enter the second annular groove 15 from the metal tube 5 , and the one-way liquid suction pipe 17 only allows the coolant to enter the first ring 16 from below.

[0039] The lower end of the triangular folding rod 13 is fixedly connected to the first reciprocating screw 21 through a bracket. The first reciprocating screw 21 is hollow. The movable shaft of the micro motor 11 passes through the inner wall of the first reciprocating screw 21. The side wall of the first reciprocating screw 21 is threadedly connected with a first slider 22. The lower end of the first slider 22 is fixedly connected to the upper end of the second ring 20 through two first rods 23.

[0040] During the rotation of the triangular folding rod 13, the first reciprocating screw 21 will be driven to rotate through multiple brackets, so that the first slider 22 drives the second ring 20 to slide up and down on the inner wall of the second annular groove 15 through the two first rods 23, so that the enclosed space composed of the upper end of the first ring 16, the inner wall of the second annular groove 15 and the lower end of the second ring 20 intermittently increases and decreases, and then the coolant can be pumped into the metal tube 5 through the one-way suction pipe 17, the one-way outlet pipe 18 and the one-way inlet pipe 19 for circulation. At this time, the flowing coolant can absorb the heat on the metal plate 6 through the metal tube 5, thereby accelerating the heat dissipation efficiency of the multiple heat dissipating fins 2.

[0041] A plurality of cooling fins 34 are fixedly connected to the bottom of the second annular groove 15. The heat absorbing end of the cooling fin 34 is located inside the second annular groove 15, and the heat releasing end of the cooling fin 34 is located outside the second annular groove 15, which can cool the coolant to keep it at a relatively low temperature.

[0042] A cleaning mechanism is provided on the fixed frame 3. The cleaning mechanism includes a second reciprocating lead screw 24 rotatably connected to the lower end of the fixed frame 3. A second slider 25 is threadedly connected to the side wall of the second reciprocating lead screw 24. A ring 27 is fixedly connected to the side wall of the second slider 25 through a plurality of second rods 26. A plurality of U-shaped cleaning plates 28 corresponding to the plurality of heat dissipation fins 2 are fixedly connected to the outer side wall of the ring 27. The inner side wall of the U-shaped cleaning plate 28 is in contact with the side wall of the corresponding heat dissipation fin 2 (as Figure 6 shown).

[0043] The driving mechanism further includes a second one-way bearing 29. The movable shaft of the micro motor 11 is fixedly connected to the inner side wall of the inner ring of the second one-way bearing 29. The outer side wall of the outer ring of the second one-way bearing 29 is fixedly connected to the side wall of the second reciprocating lead screw 24 through a plurality of brackets.

[0044] It should be noted that when the micro motor 11 rotates forward, the inner ring of the second one-way bearing 29 does not drive its outer ring to rotate. When the micro motor 11 rotates in the reverse direction, the inner ring of the second one-way bearing 29 drives its outer ring to rotate. And when the micro motor 11 rotates in the reverse direction, at this time, the plurality of metal plates 6 return to the initial position, that is, the side wall of the metal plate 6 is flush with the side wall of the heat dissipation fin 2. The control method of the reverse rotation of the micro motor 11 can be controlled by an external control mechanism, which is an existing technology.

[0045] When the micro motor 11 rotates in the reverse direction, at this time, the inner ring of the second one-way bearing 29 drives its outer ring to rotate. Furthermore, the outer side wall of the outer ring of the second one-way bearing 29 drives the second reciprocating lead screw 24 to rotate rapidly through a plurality of brackets. At this time, the side wall of the second slider 25 drives the ring 27 and the plurality of U-shaped cleaning plates 28 to move up and down rapidly through a plurality of second rods 26, scraping the dust adhering to the plurality of heat dissipation fins 2, avoiding the situation in the prior art that the heat dissipation fins 2 are exposed to the outside, so that more dust will accumulate on the heat dissipation fins 2, further affecting the heat dissipation of the heat dissipation fins 2.

[0046] The inner side wall of the fixed ring 14 is fixedly connected with a connecting cylinder 30. A plurality of impellers 31 are fixedly connected to the side wall of the second reciprocating lead screw 24 located inside the connecting cylinder 30. A plurality of air blowing pipes 32 are fixedly communicated with the bottom of the inner part of the connecting cylinder 30. The plurality of air blowing pipes 32 are all fixedly connected to the side wall of the second slider 25.

[0047] When the second reciprocating lead screw 24 rotates rapidly, at this time, the plurality of impellers 31 rotate rapidly. At this time, the plurality of impellers 31 can supply air to the plurality of air blowing pipes 32. At this time, the plurality of air blowing pipes 32 can blow air, blowing the dust cleaned from the heat dissipation fins 2 out of the lamp cover 1.

[0048] When this LED bulb lamp is in normal use, the plurality of heat dissipation fins 2 can discharge the heat on the lamp cover 1;

[0049] When the temperature in the lampshade 1 rises, the micro motor 11 rotates forward, so that the inner ring of the first one-way bearing 12 drives its outer ring to rotate, and the outer ring of the first one-way bearing 12 drives the gear ring 9 to rotate through the triangular folding rod 13, and the gear ring 9 drives the multiple metal tubes 5 to rotate through the multiple gears 10, and drives the multiple metal plates 6 to rotate, which can accelerate the air flow in the multiple heat dissipation fins 2, thereby increasing the heat dissipation effect of the multiple heat dissipation fins 2 on the lampshade 1, and avoids the prior art that when the lampshade 1 is used for a long time and the heat generated is high, the temperature of the multiple heat dissipation fins 2 is synchronously high, and the heat in the lampshade 1 cannot be dissipated in time, thereby affecting its heat dissipation efficiency;

[0050] In addition, during the rotation of the triangular folding rod 13, the first reciprocating screw 21 is driven to rotate through multiple brackets, so that the first slider 22 drives the second ring 20 to slide up and down on the inner wall of the second annular groove 15 through the two first rods 23, so that the closed space composed of the upper end of the first ring 16, the inner wall of the second annular groove 15 and the lower end of the second ring 20 is intermittently increased and decreased, and then the coolant can be pumped into the metal pipe 5 through the one-way suction pipe 17, the one-way outlet pipe 18 and the one-way inlet pipe 19 for circulation. At this time, the flowing coolant can absorb the heat on the metal plate 6 through the metal pipe 5, thereby accelerating the heat dissipation efficiency of the multiple heat dissipating fins 2;

[0051] After the temperature in the lampshade 1 drops, the micro motor 11 stops rotating forward, and the multiple metal plates 6 return to the initial position, that is, the side wall of the metal plate 6 is flush with the side wall of the heat sink 2, and then the micro motor 11 is controlled to rotate in the opposite direction. At this time, the inner ring of the second one-way bearing 29 drives its outer ring to rotate, and then the outer ring side wall of the second one-way bearing 29 drives the second reciprocating screw 24 to rotate rapidly through multiple brackets. At this time, the side wall of the second slider 25 drives the ring 27 and the multiple U-shaped cleaning plates 28 to move up and down rapidly through multiple second rods 26 to scrape off the dust adhered to the multiple heat sink 2, so as to avoid the heat sink 2 being in the outside in the prior art, so that more dust will accumulate on the heat sink 2, further affecting the heat dissipation of the heat sink 2;

[0052] When the second reciprocating screw 24 rotates rapidly, the multiple impellers 31 rotate rapidly, and the multiple impellers 31 can deliver air to the multiple blowing pipes 32, and the multiple blowing pipes 32 can blow air to blow the dust cleaned from the heat dissipation fins 2 out of the lampshade 1;

[0053] When the micro motor 11 stops rotating after cleaning is completed, the plurality of U-shaped cleaning plates 28 are located at the initial position, and will not affect the subsequent rotation of the plurality of metal plates 6 .

[0054] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
