[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 comprises a plurality of through grooves opened in the side walls of the plurality of heat dissipation fins 2, the inner walls of the plurality of through grooves are rotationally connected with metal pipes 5, the side walls of the plurality of metal pipes 5 are fixedly connected with metal plates 6, the side walls of the plurality of metal plates 6 are respectively attached to the inner walls of the plurality of through grooves, it should be noted that the two inner walls of the through groove close to the metal plate 6 are arc-shaped, and the arc centers thereof coincide with the center of the metal pipe 5, so that the through groove does not hinder the rotation of the metal plate 6 during the rotation of the metal pipe 5 driving the metal plate 6, a first annular groove 7 is opened in the inner side wall of the fixed frame 3, a plurality of sliders 8 capable of revolving are slidingly connected to the inner wall of the first annular groove 7, the side walls of the plurality of sliders 8 close to each other are fixedly connected with a gear ring 9, the side walls of the plurality of metal pipes 5 penetrate through the inner bottom of the fixed frame 3, the side walls of the plurality of metal pipes 5 located in the fixed frame 3 are fixedly connected with a plurality of gears 10, and the inner side wall of the gear ring 9 is engaged with the side walls of the plurality of gears 10.

[0033] A driving mechanism is arranged on the lamp shell 4, the driving mechanism comprises a first one-way bearing 12, a micro motor 11 is fixedly connected to the inner wall of the lamp shell 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, the outer ring side wall of the first one-way bearing 12 is fixedly connected with a triangular folding rod 13, and the lower ends of the triangular folding rods 13 are fixedly connected with the upper ends of the gear ring 9.

[0034] It should be noted that when the micro motor 11 rotates forward, the inner ring of the first one-way bearing 12 drives the outer ring to rotate, and when the micro motor 11 reverses, the inner ring of the first one-way bearing 12 does not drive the outer ring to rotate, and a temperature sensor (not shown in the figure) is arranged in the lampshade 1, when the temperature sensor senses that the temperature in the lampshade 1 is high, at this time the micro motor 11 is controlled to rotate forward by an external control mechanism, and the control mode is the prior art.

[0035] When the temperature in the lampshade 1 rises, the micro motor 11 rotates forward at this time, so that the inner ring of the first one-way bearing 12 drives the outer ring to rotate, the outer ring of the first one-way bearing 12 drives the gear ring 9 to rotate through the triangular folding rod 13, the gear ring 9 drives the plurality of metal pipes 5 to rotate through the plurality of gears 10, and drives the plurality of metal plates 6 to rotate, which can accelerate the air flow in the plurality of heat dissipation fins 2, thereby increasing the heat dissipation effect of the plurality of 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, the heat generated is high, at this time the temperature of the plurality of heat dissipation fins 2 is also high, which cannot dissipate the heat in the lampshade 1 in time, thereby affecting the heat dissipation efficiency.

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

[0037] Cooling liquid 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. 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 cooling liquid.

[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, and 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 to the 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 liquid outlet pipe 18 and the one-way liquid 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 low temperature.

[0042] The fixing frame 3 is provided with a cleaning mechanism, which includes a second reciprocating screw 24 rotatably connected to the lower end of the fixing frame 3, a second slider 25 being threadedly connected to the side wall of the second reciprocating screw 24, a ring 27 being 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 dissipating fins 2 being fixedly connected to the outer wall of the ring 27, and the inner side wall of the U-shaped cleaning plate 28 being in contact with the side wall of the corresponding heat dissipating fin 2 (such as Figure 6 shown).

[0043] The drive mechanism also includes a second one-way bearing 29, the movable shaft of the micro motor 11 is fixedly connected to the inner ring side wall of the second one-way bearing 29, and the outer ring side wall of the second one-way bearing 29 is fixedly connected to the side wall of the second reciprocating screw 24 through multiple 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 reversely, the inner ring of the second one-way bearing 29 drives its outer ring to rotate. When the micro motor 11 rotates reversely, the multiple metal plates 6 return to their initial positions, that is, the side walls of the metal plates 6 are flush with the side walls of the heat dissipation fins 2. The control method for 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 opposite direction, the inner ring of the second one-way bearing 29 drives its outer ring to rotate, and then the side wall of the outer ring 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 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 sinks 2, avoiding the heat sink 2 in the prior art being in the outside world, so that more dust will accumulate on the heat sink 2, further affecting the heat dissipation of the heat sink 2.

[0046] The inner wall of the fixed ring 14 is fixedly connected to a connecting cylinder 30, and the side wall of the second reciprocating screw 24 located inside the connecting cylinder 30 is fixedly connected to multiple impellers 31. The bottom of the connecting cylinder 30 is fixedly connected to multiple blowing pipes 32, and the multiple blowing pipes 32 are all fixedly connected to the side wall of the second slider 25.

[0047] When the second reciprocating screw 24 rotates rapidly, the multiple impellers 31 rotate rapidly, and the multiple impellers 31 can supply air to the multiple blowing pipes 32. At this time, the multiple blowing pipes 32 can blow air to blow the dust cleaned from the heat dissipating fins 2 out of the lampshade 1.

[0048] When the LED bulb is in normal use, the multiple heat dissipation fins 2 can dissipate the heat from the lampshade 1;

[0049] When the temperature inside the lampshade 1 rises, the micromotor 11 rotates forward, causing the inner ring of the first one-way bearing 12 to drive its outer ring to rotate. The outer ring of the first one-way bearing 12 drives the gear ring 9 to rotate through the triangular folding rod 13. 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. This 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. This avoids the problem in the prior art that when the lampshade 1 is used for a long time and generates high heat, 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.

[0050] Furthermore, 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 enclosed space formed by 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 liquid suction pipe 17, the one-way liquid outlet pipe 18, and the one-way liquid 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;

[0051] After the temperature inside the lampshade 1 drops, the micro motor 11 stops rotating forward, and the multiple metal plates 6 return to their initial positions, that is, the side walls of the metal plates 6 are flush with the side walls of the heat dissipating fins 2. 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 side wall of the outer ring 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 the multiple second rods 26 to scrape off the dust adhered to the multiple heat dissipating fins 2, thereby avoiding the heat dissipating fins 2 being in the outside world in the prior art, so that more dust will accumulate on the heat dissipating fins 2, further affecting the heat dissipation of the heat dissipating fins 2.

[0052] When the second reciprocating screw 24 rotates rapidly, the multiple impellers 31 rotate rapidly, and the multiple impellers 31 can supply air to the multiple blowing pipes 32. At this time, 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 embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
