Description

Technical Field

[0001] This invention relates to the field of ventilation and lighting equipment technology, specifically an adjustable ceiling fan light. Background Technology

[0002] Ceiling fan lights, as integrated home appliances that combine lighting and ventilation functions, are widely used in homes, offices and other settings due to their high space utilization and strong functional versatility. The core structure of existing ceiling fan lights typically includes a lamp frame, lighting module, fan blade assembly and drive mechanism. Its working principle is mainly to drive airflow through the rotation of fan blades to achieve ventilation and heat dissipation, while providing lighting through the lamp body.

[0003] Existing ceiling fan lights typically only transmit airflow during operation to achieve heat dissipation and cooling. However, because the fan blades and lighting are combined, the rotation of the fan blades during lighting operation usually transmits the heat generated by the lighting synchronously. As a result, the temperature of the flowing air gradually increases over time, directly leading to a reduction in its cooling and heat dissipation effect. Therefore, this invention provides a ceiling fan light with adjustable airflow direction to solve the above-mentioned problems. Summary of the Invention

A connecting ring is fixedly installed at the bottom of the bottom sealing block. The top sealing plate is located at the top of the inner cylinder, and a top sealing groove is provided around the top of the inner cylinder at intervals. The top slot and the top sealing groove are staggered. A support rod is fixedly installed between the top sealing plate and the bottom sealing block. The inner ring of the top sealing plate is connected to the adjustment control component.

[0010] As a further embodiment of the present invention, the adjusting control component includes a lifting cylinder, which is fitted onto the outside of the rotating shaft. The outer wall of the rotating shaft is provided with an inner groove spaced around it, and the inner wall of the lifting cylinder is provided with an inner strip spaced around it. The positions of the inner strip and the inner groove correspond to each other.

[0011] As a further embodiment of the present invention, the active impeller is provided with teeth around its perimeter, and driven wheels are provided at intervals around the inner side of the active impeller. The outer wall of the driven wheels is also provided with teeth. The teeth on the outer wall of the driven wheels and the teeth on the inner wall of the active impeller mesh with each other. A fixed shaft is movably mounted on the inner ring of the driven wheels. The two ends of the fixed shaft are mounted on the side wall of the fixed impeller. An active wheel is installed on the inner side of the active impeller corresponding to the position of the lifting cylinder. The outer wall of the active wheel is provided with teeth, and the teeth on the outer wall of the active wheel and the teeth on the outer wall of the driven wheel mesh with each other.

[0012] As a further embodiment of the present invention, the inner wall of the drive wheel is provided with an outer groove at intervals, and the outer wall of the lifting cylinder is fixedly installed with an outer adjustment strip at intervals corresponding to the position of the drive impeller. The bottom of the outer groove is provided with a guide groove, which gradually narrows from bottom to top.

[0014] Compared with the prior art, the beneficial effects of the present invention are: 1. When using this invention, by adjusting the control components, the sealing plate will block the bottom of the air duct, and at the same time, the top of the inner cylinder will be opened, so that the airflow compression component in the inner cylinder will start and operate, compressing the airflow and transmitting it to the vortex conduction component. Under the vortex regulation of the vortex conduction component, the cold airflow will be transmitted outward through the ventilation slot, which can not only cool the lamps, but also effectively cool the working area, thereby greatly improving its cooling and heat dissipation effect.

[0015] 2. When using this invention, by adjusting the control components, it is possible to selectively switch between conventional ventilation and cooling and cold airflow ventilation, enabling it to be used selectively according to needs and greatly improving its applicability.

[0016] 3. When using this invention, the hot airflow generated in the eddy current conduction component is transmitted to the guide cavity, which heats the airflow input end of the fan component. This causes the transmitted airflow to expand and dry due to the heat, and then provides a high compression strength after being transmitted to the airflow compression component. This facilitates the airflow to work in the eddy current conduction component. Furthermore, the compressed airflow has a lower moisture content after being transmitted to the eddy current conduction component, making it less likely to condense in the eddy current conduction component.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-9In this embodiment of the invention, an adjustable ceiling fan light includes a light frame 1, a support cylinder 2 fixedly installed on the top of the light frame 1, the interior of the support cylinder 2 being hollow, a lighting lamp installed at the bottom of the light frame 1, and a control main board installed inside the light frame 1. The ceiling fan light can be connected to a customer's mobile terminal through the control main board. After connection, the light and speed can be adjusted through the customer's mobile terminal. A ventilation slot 3 is provided at the bottom of the light frame 1, and the interior of the ventilation slot 3 is interconnected with the interior of the support cylinder 2. A fan assembly is installed inside the support cylinder 2, and the airflow output end of the fan assembly corresponds to the position of the ventilation slot 3. An adjusting blade 4 is movably installed at intervals on the inner bottom of the ventilation slot 3. The adjusting blade 4 can be rotated and adjusted within the ventilation slot 3. By adjusting the direction of the adjusting blade 4, the direction of the wind transmitted outward through the ventilation slot 3 can be changed. An air inlet slot 5 is provided at intervals on the side wall of the support cylinder 2, and the air inlet slot 5 is interconnected with the interior of the support cylinder 2. The air inlet slot 5 is located at the airflow input end of the fan assembly.

[0029] An airflow compression component is installed inside the fan assembly, and an eddy current conduction component is installed inside the support cylinder 2. The airflow output end of the airflow compression component and the airflow input end of the eddy current conduction component are connected to each other. The compressed airflow can be cooled and discharged through the eddy current conduction component. The airflow output end of the eddy current conduction component is connected to the ventilation slot 3. A sealing component is installed inside the fan assembly and the airflow compression component. The sealing component can block the airflow output end of the fan assembly. When the sealing component is open, the airflow input end of the airflow compression component will be opened. Conversely, when the sealing component opens the airflow output end of the fan assembly, the airflow input end of the airflow compression component will be blocked. The airflow compression component includes an adjustment control component. The adjustment control component can start and stop the airflow compression component. The adjustment control component and the sealing component are connected to each other. The adjustment control component controls the opening and closing of the airflow compression component and can also control the adjustment of the sealing component. That is, when the airflow compression component is started, its corresponding airflow input end is opened, and vice versa.

[0030] The fan assembly includes a fan duct 7, which is installed inside a support cylinder 2. The inside of the fan duct 7 is hollow, and the hollow area inside the fan duct 7 is connected to the ventilation slot 3. A fixed cylinder 10 is installed inside the fan duct 7, and a drive motor is installed on the bottom inner side of the fixed cylinder 10. Fan blades 8 are provided on the inner side of the fan duct 7. A rotating shaft 26 is installed on the output end of the drive motor, and the rotating shaft 26 and the fan blades 8 are connected to each other. When the drive motor is started, it can drive the fan blades 8 to rotate inside the fan duct 7, thereby transmitting airflow to the ventilation slot 3 and exhausting it outward through the ventilation slot 3.

[0031] The airflow compression assembly includes an inner cylinder 9, an active impeller 11, and a fixed impeller 12. The inner cylinder 9 is installed inside the air duct 7 and is hollow, dividing the air duct 7 into an inner cavity and an outer cavity. The active impeller 11 and the fixed impeller 12 are installed at intervals on the fixed cylinder 10, and are staggered. The fixed impeller 12 is fixedly installed on the fixed cylinder 10, and the active impeller 11 is movably installed on the fixed cylinder 10, allowing the active impeller 11 to rotate on the fixed cylinder 10. An adjustment control component is installed inside the fixed cylinder 10 corresponding to the positions of the active impeller 11 and the fixed impeller 12, and is movably installed on the rotating shaft 26. By adjusting the adjustment control component, the active impeller 11 can be driven to rotate inside the inner cylinder 9, thereby guiding and transmitting the airflow transmitted by the fan blade 8 to the inner cylinder 9, and then transmitting it to the vortex conduction assembly through the inner cylinder 9. Furthermore, both the active impeller 11 and the fixed impeller 12 are equipped with blades at an angle, and the blades on the active impeller 11 and the fixed impeller 12 are tilted at opposite angles. When the active impeller 11 rotates, the blades on the active impeller 11 can conduct the airflow into the inner cylinder 9. When the airflow passes through two adjacent sets of blades on the active impeller 11, it will be blocked by the blades on the fixed impeller 12. Since the blades on the active impeller 11 and the fixed impeller 12 are tilted at opposite angles, the airflow needs to be conducted with an angle shift, thus hindering the smooth conduction of the airflow and reducing the transmission speed of the airflow at this point. However, the airflow generated by the rotation of the fan blade 8 continues to be conducted, and the subsequent airflow will accumulate between the active impeller 11 and the fixed impeller 12. As the operation is repeated, the intensity of the accumulated airflow will gradually increase, thereby significantly increasing the intensity of the airflow transmitted into the inner cylinder 9.

[0032] The eddy current conduction assembly includes an regulating pipe 18, the bottom of which is connected to the interior of the ventilation slot 3. An regulating block 19 is installed on the bottom side wall of the regulating pipe 18. A conduction air cavity 38 is formed on the side wall of the regulating block 19; the conduction air cavity 38 is an annular cavity. Spiral grooves 39 are spaced around the top of the regulating block 19; the spiral grooves 39 are inclined arc-shaped grooves and are connected to the conduction air cavity 38. A return pipe 40 is fixedly installed at the top of the regulating block 19. A guide pipe is fixedly installed on the inner top of the regulating pipe 18 corresponding to the position of the return pipe 40. Cone 41, guide cone 41 is a conical block, the conical end of guide cone 41 is inserted into the top of the inner side of return pipe 40, and there is a gap between guide cone 41 and the top of return pipe 40 for airflow. A connector 20 is installed on the outer wall of adjusting block 19 on the side corresponding to the fan assembly, and connector 20 and conduction air cavity 38 are interconnected. A transmission pipe 21 is installed on connector 20. The end of transmission pipe 21 away from connector 20 is connected to airflow compression assembly. Specifically, the end of transmission pipe 21 away from connector 20 passes through the side wall of inner cylinder 9 and is interconnected with the inside of inner cylinder 9.

[0033] When the compressed high-pressure airflow is transmitted to the conduction air cavity 38 through the transmission pipe 21, it will spiral upward and be closely attached to the inner wall of the regulating pipe 18 by the spiral groove 39 on the regulating block 19. Under the action of centrifugal force, the kinetic energy is converted into internal energy, which causes its temperature to rise. When it is transmitted to the guide cone 41, it is guided to the return pipe 40 through the cone end of the guide cone 41. At this time, the rotation radius decreases, which leads to an increase in angular velocity, volume expansion, and pressure reduction. The inner airflow and the outer airflow generate countercurrent heat exchange, which in turn significantly reduces the temperature of the internal airflow. When the airflow is discharged through the bottom of the return pipe 40, a significant low temperature effect is produced.

[0034] The sealing component includes a bottom sealing plate 13 and a top sealing plate 17. The bottom sealing plate 13 is fixedly installed around the inner wall of the air duct 7 at intervals. The end of the bottom sealing plate 13 away from the inner wall of the air duct 7 is fixedly installed on the outer wall of the inner cylinder 9. A bottom groove 22 is provided at the bottom of the bottom sealing plate 13. A bottom sealing block 14 is provided between two adjacent sets of bottom sealing plates 13. A connecting ring 15 is fixedly installed at the bottom of the bottom sealing block 14. Multiple sets of bottom sealing blocks 14 are connected to each other through the connecting ring 15, and the connecting ring 15 can be snapped into the bottom groove 22 at the bottom of the bottom sealing plate 13. The top sealing plate 17... 7 is set on the top of the inner cylinder 9. The top sealing plate 17 is provided with top sealing grooves 23 spaced around it. The top of the inner cylinder 9 is provided with top locking grooves 29 spaced around it. The top locking grooves 29 and top sealing grooves 23 are staggered. The top sealing plate 17 can be locked onto the top locking grooves 29 through the top sealing grooves 23, thereby sealing the top of the inner cylinder 9. A support rod 16 is fixedly installed between the top sealing plate 17 and the bottom sealing block 14. The bottom sealing block 14 and the top sealing plate 17 are connected by the support rod 16. The inner ring of the top sealing plate 17 is connected to the adjustment control component.

[0035] When the adjusting control unit controls the top sealing plate 17 to rise and open the top slot 29 at the top of the inner cylinder 9, the bottom sealing block 14 will rise synchronously and move between the two adjacent sets of bottom sealing plates 13 to block the gap between the two sets of bottom sealing plates 13. At this time, the bottom of the air duct 7 will be completely blocked. Conversely, when the adjusting control unit controls the top sealing plate 17 to fall and block the top slot 29 at the top of the inner cylinder 9, the bottom sealing block 14 will fall synchronously and move out of the area between the two adjacent sets of bottom sealing plates 13, so that the area between the two sets of bottom sealing plates 13 is no longer blocked, thereby opening the bottom of the air duct 7.

[0036] The adjustment control component includes a lifting cylinder 25, which is fitted onto the outside of a rotating shaft 26. The outer wall of the rotating shaft 26 has spaced-around inner grooves 33, and the inner wall of the lifting cylinder 25 has spaced-around inner retaining strips 34. The positions of the inner retaining strips 34 and the inner grooves 33 correspond to each other. The lifting cylinder 25 is secured to the outer wall of the rotating shaft 26 by the inner retaining strips 34, allowing it to be adjusted in height on the outer wall of the rotating shaft 26. Simultaneously, the lifting cylinder 25 rotates synchronously with the rotating shaft 26. The driving impeller 11 has teeth arranged around its perimeter, and driven wheels 31 are spaced-around around its inner side. The outer wall of the driven wheels 31 also has teeth, which mesh with the teeth on the inner wall of the driving impeller 11. A fixed shaft 32 is movably mounted on the inner ring of the driven wheels 31, with both ends of the fixed shaft 32 mounted on the side walls of the fixed impeller 12. An active wheel 35 is installed on the inner side of the active impeller 11 corresponding to the position of the lifting cylinder 25. The outer wall of the active wheel 35 is provided with teeth. The teeth on the outer wall of the active wheel 35 and the teeth on the outer wall of the driven wheel 31 mesh with each other. The rotation of the active wheel 35 can drive the driven wheel 31 to rotate, which in turn drives the active impeller 11 to rotate on the fixed cylinder 10. The inner wall of the active wheel 35 is provided with an outer slot 36 at intervals. The outer wall of the lifting cylinder 25 is fixedly installed with an outer adjustment bar 30 at intervals corresponding to the position of the active impeller 11. The outer adjustment bar 30 can be snapped into the outer slot 36. The rotation of the lifting cylinder 25 can drive the active wheel 35 to rotate. The bottom of the outer slot 36 is provided with a guide groove 37. The guide groove 37 gradually narrows from bottom to top. The guide groove 37 makes the bottom ends of two adjacent sets of outer slots 36 conical, and the top of the outer adjustment bar 30 is also conical.

[0037] In the initial state, the external adjustment bar 30 on the lifting cylinder 25 is located in the inner ring of the fixed impeller 12. When the lifting cylinder 25 rises, the external adjustment bar 30 on the outer wall of the lifting cylinder 25 will be inserted into the outer groove 36 from bottom to top through the guide groove 37, thereby driving the drive wheel 35 to rotate. At the same time, the guide groove 37 makes it easier for the external adjustment bar 30 to be inserted into the outer groove 36 when it moves upward, and will not affect the rotation efficiency of the rotating shaft 26, thus preventing the operation from being obstructed.

[0038] The adjustment control components also include a top support plate 24 and a telescopic device 28. The top support plate 24 is installed on the sealing cavity component. Specifically, the top support plate 24 is installed on the inner ring of the top sealing plate 17. The telescopic device 28 is installed at the top of the fixed cylinder 10. The top output end of the telescopic device 28 is connected to the bottom of the top support plate 24. The telescopic device 28 includes, but is not limited to, an electric push rod. The telescopic device 28 can control the lifting and lowering adjustment of the top support plate 24. An adjustment plate 27 is provided at the top of the top support plate 24. The adjustment plate 27 is fixedly connected to the outer wall of the lifting cylinder 25. The bottom of the adjustment plate 27 and the top of the top support plate 24 are in contact with each other. A sliding component that facilitates sliding can be installed between the adjustment plate 27 and the top support plate 24. The sliding component includes, but is not limited to, balls or bearings, so that the adjustment plate 27 can be lifted by the top support plate 24 and can also rotate on the top support plate 24.

[0039] A guide cavity 42 is provided on the inner side of the support cylinder 2. The guide cavity 42 is located above the air inlet groove 5 and is connected to the top of the regulating pipe 18. An exhaust groove 6 is provided around the outer wall of the support cylinder 2 at intervals. The exhaust groove 6 penetrates the side wall of the support cylinder 2 and is connected to the guide cavity 42. The hot airflow at the top of the regulating pipe 18 will be transmitted to the guide cavity 42 and heat the area of ​​the guide cavity 42. At this time, since the guide cavity 42 is located above the air inlet groove 5, that is, above the airflow input end of the fan assembly, the guide cavity 42 will heat the airflow input end of the fan assembly, so that the transmitted airflow is heated, expands and dries. After being transmitted to the airflow compression assembly, it can provide a high compression strength. After the compressed airflow is transmitted to the vortex conduction assembly, the water content is reduced and it is not easy to form a condensation state in the vortex conduction assembly. Dust filters can be installed on the outer walls of both the air inlet slot 5 and the air outlet slot 6 to protect the interior of the lamp. Furthermore, a heat insulation sleeve is provided on the inner side of the wire threading area of ​​the support cylinder 2 corresponding to the position of the guide cavity 42 to prevent the high temperature inside the guide cavity 42 from affecting the transmission line; Furthermore, by setting the fan assembly and eddy current conduction assembly at intervals, the interval area facilitates the passage of the transmission line, which can effectively avoid the situation of being affected by the transmission line during normal operation.

[0040] By adjusting the control components, the sealing components can be adjusted accordingly, allowing the bottom of the air duct 7 and the top of the inner cylinder 9 to be selectively opened. When the bottom of the air duct 7 is open, the top of the inner cylinder 9 is sealed. At this time, the active impeller 11 on the fixed cylinder 10 will not rotate, and the airflow will be transmitted to the ventilation slot 3 through the rotation of the fan blades 8. When the bottom of the air duct 7 is sealed, the top of the inner cylinder 9 will be opened. At this time, the active impeller 11 on the fixed cylinder 10 will rotate by moving the external adjustment bar 30 through the lifting cylinder 25, guiding the airflow generated by the rotation of the fan blades 8 to the inner cylinder 9. The airflow is then compressed in the inner cylinder 9 in conjunction with the active impeller 11 and the fixed impeller 12. The compressed airflow is then transmitted to the vortex conduction component, which transmits the cooled airflow to the ventilation slot 3, thereby completing the cooling process.

[0041] The working principle of this invention is: In use, after the lamp is installed in the designated position, the telescopic device 28 is selectively adjusted in height according to requirements. When the telescopic device 28 is adjusted upward, it will drive the sealing component and the lifting cylinder 25 to rise, thus sealing the bottom of the air duct 7 and opening the top of the inner cylinder 9. At the same time, the rise of the lifting cylinder 25 will drive the outer adjustment bar 30 to move into the outer groove 36, thereby causing the active impeller 11 to rotate through the active wheel 35 and the driven wheel 31, guiding the airflow transmitted by the fan blade 8 into the inner cylinder 9. The active impeller 11 and the fixed impeller 12 work together to compress the airflow. The airflow is transmitted to the regulating block 19, and spirals upward in the regulating pipe 18 through the spiral groove 39 at the top of the regulating block 19. Under the action of centrifugal force, kinetic energy is converted into internal energy, causing its temperature to rise. When it is transmitted to the guide cone 41, it is guided by the cone end of the guide cone 41 to the return pipe 40. At this time, the rotation radius decreases, resulting in an increase in angular velocity, volume expansion, and pressure reduction. The inner airflow and the outer airflow generate countercurrent heat exchange, which in turn significantly reduces the temperature of the internal airflow. Consequently, the temperature of the airflow transmitted from the bottom of the regulating pipe 18 to the ventilation slot 3 is significantly reduced, thereby enabling the cooling of the working area with cold airflow. When the telescopic device 28 descends, it will cause the sealing component and the lifting cylinder 25 to descend, thus sealing the top of the inner cylinder 9 and opening the bottom of the air duct 7. At the same time, the descent of the lifting cylinder 25 will cause the outer adjustment strip 30 to move out of the outer slot 36, so that the active impeller 11 stops rotating. At this time, the airflow generated by the rotation of the fan blade 8 will be directly transmitted to the ventilation slot 3 through the air duct 7, thereby enabling heat dissipation of the working area.
