Description

Technical Field

[0001] The present invention relates to the technical field of intelligent lighting, and particularly to a turbulent flow type intelligent lighting device and method based on Wi-Fi mesh technology. Background Art

[0002] Currently, lighting devices based on Wi-Fi mesh technology only simply connect and control the on / off through a wireless network, and the control methods and functionality are relatively single.

[0003] Chinese Patent Application CN117006450A discloses an intelligent lighting device based on Wi-Fi mesh technology, including a top assembly box fixedly installed on the indoor ceiling by bolts, an electric control elevator installed inside the top assembly box, an outer housing installed outside the top assembly box, an aluminum substrate installed on the inner top surface of the outer housing, and a lighting source controlled by Wi-Fi mesh technology installed at the lower end of the aluminum substrate. An annular peripheral assembly disk is installed inside the outer housing around the aluminum substrate, a flip-type driving blade is installed inside the annular peripheral assembly disk, the upper end of the outer arc surface of the top assembly box has an upwardly bent upper closing housing, the lower end of the outer arc surface of the outer housing has a downwardly bent lower closing housing, the upper edge position of the aluminum substrate has an upwardly protruding inner extrusion ring, and a driving motor for controlling the annular peripheral assembly disk is installed on one side inside the top assembly box. The upper closing housing and the lower closing housing have an arc-shaped protrusion on one assembly surface, and an arc-shaped groove matching the arc-shaped protrusion is provided on the other assembly surface of the upper closing housing and the lower closing housing.

[0004] The above solution combines a fan with a lamp. In the prior art, there are also many devices that combine a fan with a lamp, and for aesthetics, most fans can achieve a telescopic function. As described in the above solution, however, due to the limitation of the size of the lighting fixture, the length that the fan can extend is limited. Thus, the blowing area formed by the fan combined with the fixture is limited, and most fans will extend only when in use and retract into the fixture when not in use. Moreover, since the fixture itself does not have a self-cleaning function, a large amount of dust will adhere to the fan after long-term use and cannot be cleaned. Summary of the Invention

[0005] To address the above problems, a turbulator intelligent lighting device and method based on the wifimesh technology are provided. By setting the first fan blade and the second fan blade, and while pushing out the first fan blade through the pushing unit, the first extrusion cavity located on one side of the first fan blade is squeezed, so that the second fan blade slides out from the first fan blade, and finally the total length of the first fan blade and the second fan blade becomes longer, expanding the blowing area. At the same time, by setting a cleaning unit on the side wall of the rotating ring, the first fan blade and the second fan blade during contraction are automatically cleaned, reducing the subsequent cleaning workload of the first fan blade and the second fan blade.

[0006] To solve the problems of the prior art, the present invention provides a turbulator intelligent lighting device based on the wifimesh technology, including a lamp body and a blowing unit arranged above the lamp body; the lamp body is of a circular structure, and the blowing unit includes a rotating ring arranged on the upper part of the lamp body. The axis of the rotating ring is collinear with the axis of the lamp body, and the rotating ring can rotate around its own axis. A first fan blade is movably arranged along the radial direction of the lamp body on one side of the inner ring of the rotating ring. A second fan blade is sleeved outside the first fan blade. The second fan blade is slidably matched with the first fan blade along the extension direction of the first fan blade. The second fan blade penetrates through the peripheral wall of the rotating ring and is slidably matched with the rotating ring. There is a first gap between the end of the first fan blade far from the second fan blade and the inner ring of the rotating ring. A first extrusion cavity is arranged along the extension direction of the first fan blade in the first gap. A pushing unit for driving the first fan blade to move is arranged on one side of the first fan blade. An air vent groove is opened in the first fan blade, and the first extrusion cavity is communicated with the inside of the second fan blade through the air vent groove.

[0007] Preferably, the first extrusion cavity is jointly formed by a first corrugated sleeve and a second corrugated sleeve. The first corrugated sleeve is sleeved outside the first fan blade, and both ends of the first corrugated sleeve are respectively fixedly connected with the side wall of the inner ring of the rotating ring and the end of the first fan blade. The second corrugated sleeve is sleeved outside the first corrugated sleeve, and both ends of the second corrugated sleeve are respectively fixedly connected with the end of the first fan blade and the side wall of the inner ring of the rotating ring.

[0008] Preferably, the pushing unit includes a support disk arranged at the bottom of the first fan blade and a pushing disk arranged at the upper part of the first fan blade. The axis of the support disk is collinear with the axis of the pushing disk, and the axis of the support disk is collinear with the axis of the lamp body. A plurality of inclined grooves are opened in the pushing disk. The extension direction of the inclined grooves has an included angle with the radial direction of the pushing disk, and the included angle is an acute angle. A guiding groove is opened in the support disk along the radial direction of the support disk. The upper part of the first fan blade extends into the inclined grooves and is slidably matched with the inclined grooves along the extension direction of the inclined grooves. The lower part of the first fan blade extends into the guiding groove and is slidably matched with the guiding groove along the extension direction of the guiding groove. A first magnetic driving unit for driving the pushing disk to rotate is arranged on the pushing disk.

[0009] Preferably, a plurality of first attracting sheets are uniformly arranged around the axis of the pushing disk at the lower part of the pushing disk, and a plurality of first electromagnetic sheets are uniformly arranged around the axis of the supporting disk at the upper part of the supporting disk. The first electromagnetic sheets generate magnetism when electrified and attract the first attracting sheets, and the first electromagnetic sheets are electrified in sequence around a fixed direction.

[0010] Preferably, a cleaning unit is arranged on the rotating ring. The cleaning unit includes a ring sleeve arranged on the side wall of the rotating ring. The second fan blades pass through the ring sleeve. A brush is fixedly arranged on the inner ring side of the ring sleeve. The brush is in sliding fit and in contact with the surfaces of the first fan blades and the second fan blades.

[0011] Preferably, a third corrugated sleeve is arranged at one end of the first fan blade away from the side wall of the rotating ring. The third corrugated sleeve is arranged at the end of the first fan blade along the moving direction of the first fan blade. There is a blowing cavity between the first corrugated sleeve and the second fan blade in a contracted state. The third corrugated sleeve forms a second extrusion cavity. The second extrusion cavity communicates with the blowing cavity. When the first fan blade contracts, the second extrusion cavity is extruded, and the second extrusion cavity squeezes the air inside itself into the blowing cavity and discharges it from the joint between the rotating ring and the second fan blade.

[0012] Preferably, a collecting ring is fixedly arranged on the periphery of the lamp body. A plurality of collecting grooves are formed in the collecting ring. The collecting grooves are uniformly distributed around the axis of the collecting ring on the collecting ring. The upper opening of the collecting groove is larger than the lower opening of the collecting groove. A collecting box for collecting dust is arranged at the lower part of the collecting ring.

[0013] Preferably, a groove is formed in the upper part of the supporting disk. A locking unit is arranged in the groove. The locking unit includes an electromagnet arranged at the bottom of the groove. A spring is vertically arranged above the electromagnet. A locking block is arranged at the upper part of the spring. The electromagnet can attract the locking block after being electrified. The locking block is in sliding fit and key connection with the groove. A locking groove is vertically formed at the bottom of the pushing disk. The locking block is in clamping fit with the locking groove. The cross section of the locking block is a non-circular structure, and the cross section shape of the locking groove fits the cross section shape of the locking block.

[0014] Preferably, the mounting plate is arranged above the pushing unit. An extension rod is fixedly arranged vertically at the lower part of the mounting plate. Threads are formed on the side wall at the bottom of the extension rod. The extension rod penetrates through the pushing disk and the supporting disk in sequence from top to bottom in the vertical direction and is in threaded fit with the upper part of the lamp body.

[0015] The present invention also relates to a turbulent flow type intelligent lighting method based on the wifimesh technology, and adopts a turbulent flow type intelligent lighting device based on the wifimesh technology. The specific steps are as follows:

[0016] S1. When blowing is required, the pushing unit pushes the first fan blade to move along the radial direction of the lamp body and slide out from the side wall of the rotating ring. During the process of the first fan blade sliding out from the side wall of the rotating ring, the first fan blade squeezes the first extrusion cavity, and the air in the first extrusion cavity flows into the interior of the second fan blade through the ventilation groove in the first fan blade. The second fan blade extends synchronously on the first fan blade when the first fan blade slides out.

[0017] S2. When the pushing unit completely pushes out the first fan blade, the second fan blade slides to the end of the first fan blade away from the rotating ring. At this time, the total length of the first fan blade and the second fan blade is the longest. Subsequently, the rotating ring starts to rotate around the lamp body.

[0018] S3. After the rotation is completed, the pushing unit drives the first fan blade to retract into the rotating ring, the first extrusion cavity stretches, and the air in the second fan blade flows into the first extrusion cavity through the ventilation groove. The second fan blade resets to its initial state on the first fan blade.

[0019] The beneficial effects of the present invention compared with the prior art are as follows:

[0020] 1. When blowing is required, the pushing unit is started first to push the first fan blade located on one side of the inner ring of the rotating ring, so that the first fan blade drives the second fan blade sleeved on the outer periphery of the first fan blade to move along the radial direction of the lamp body. The second fan blade slides in cooperation with the rotating ring along the radial direction of the lamp body under the drive of the first fan blade. The first fan blade drives the second fan blade to gradually extend. Since there is a first gap between the end of the first fan blade and the inner ring of the rotating ring, and a first extrusion cavity is provided on the first gap, when the first fan blade moves along the radial direction of the lamp body under the action of the pushing unit, the end of the first fan blade forms a squeeze on the first extrusion cavity. The air in the squeezed first extrusion cavity flows into the second fan blade through the ventilation groove in the first fan blade. In this way, the second fan blade sleeved on the first fan blade starts to slide. That is, when the first fan blade moves towards the side wall of the rotating ring under the action of the pushing unit, the second fan blade sleeved on the first fan blade also starts to move synchronously. The second fan blade slides out from the first fan blade. When the end of the first fan blade away from the second fan blade moves close to the side wall of the rotating ring, the first fan blade is completely extended, and at this time, the second fan blade sleeved on the first fan blade also completely slides out from the second fan blade. At this time, the total length of the first fan blade and the second fan blade reaches the maximum. Compared with the traditional lamp body with a fan, without changing the size of the lamp body, the present intelligent lighting device expands the blowing area of the blowing unit.

[0021] 2. By providing a collar on the side wall of the rotating ring and a brush on the collar, the brush automatically cleans the surfaces of the first and second fan blades during the retraction of the first fan blade and is collected by the collection box.

[0022] 3. By providing a third corrugated sleeve, the third corrugated sleeve forms a second extrusion chamber. During the retraction of the first fan blade, the second extrusion chamber is extruded, and the air in the second extrusion chamber is discharged through the blowing cavity, forming an air flow from the inner ring of the rotating ring to the outer ring side of the rotating ring at the brush, avoiding the situation where dust attached to the first and second fan blades falls into the inner ring of the rotating ring and cannot be cleaned.

[0038] To further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0039] Refer to Figures 1 - 4:The turbulent flow type intelligent lighting device based on the wifimesh technology comprises a lamp body 1 and a blowing unit 2 arranged above the lamp body 1; the lamp body 1 is of a circular structure, and the blowing unit 2 includes a rotating ring 25 arranged on the upper part of the lamp body 1. The axis of the rotating ring 25 is collinear with the axis of the lamp body 1, and the rotating ring 25 can rotate around its own axis. A first fan blade 21 is movably arranged in the radial direction of the lamp body 1 on one side of the inner ring of the rotating ring 25. A second fan blade 22 is sleeved outside the first fan blade 21. The second fan blade 22 is slidably matched with the first fan blade 21 along the extending direction of the first fan blade 21. The second fan blade 22 penetrates through the peripheral wall of the rotating ring 25 and is slidably matched with the rotating ring 25. A first gap exists between one end of the first fan blade 21 far away from the second fan blade 22 and the inner ring of the rotating ring 25. A first extrusion cavity 23 is arranged in the first gap along the extending direction of the first fan blade 21. A pushing unit 24 for driving the first fan blade 21 to move is arranged on one side of the first fan blade 21. An air vent groove is formed in the first fan blade 21. The first extrusion cavity 23 is communicated with the inside of the second fan blade 22 through the air vent groove.

[0040] With the development of the wifimesh technology, traditional turbulent flow type intelligent lighting devices can already meet simple switching functions, including lighting color change and lighting brightness adjustment. However, with the continuous improvement of requirements, the drawback that only the lamp body 1 can be installed on the top of the room but the fan cannot be installed has emerged. In order to make up for the fan function that cannot be hoisted, users mostly use floor fans. However, unlike traditional ceiling fans, the blowing area of floor fans is limited, while the blowing area of hoisted fans is large and not easily affected by moving objects. Thus, an intelligent lighting device combining a fan and the lamp body 1 has emerged. However, the size of the fan combined with the lamp body 1 cannot be guaranteed because the length of traditional fan blades is fixed and cannot be extended or retracted, and the size of the lamp body 1 is limited. As a result, the length of the extended fan is short, and when the fan rotates, the blowing area is too small, which is not convenient for daily use.

[0041] To avoid the above situation, the blowing unit 2 provided on the lamp body 1 is redesigned. The specific working principle is as follows. During the daily use of the lighting device, the blowing unit 2 is in a non-start state. Only when the lamp body 1 is in the lighting state, when blowing is required, the blowing unit 2 is started through remote control. The remote control technology based on Wi-Fi mesh is an existing technology and will not be elaborated here. After the blowing unit 2 is started, the pushing unit 24 is started first, and the first fan blade 21 located on one side of the inner ring of the rotating ring 25 is pushed, so that the first fan blade 21 drives the second fan blade 22 sleeved on the periphery of the first fan blade 21 to move along the radial direction of the lamp body 1. The second fan blade 22 is in sliding fit with the rotating ring 25 along the radial direction of the lamp body 1 under the drive of the first fan blade 21. The first fan blade 21 drives the second fan blade 22 to gradually extend. Since there is a first gap between the end of the first fan blade 21 and the inner ring of the rotating ring 25, and a first extrusion cavity 23 is provided on the first gap, when the first fan blade 21 moves along the radial direction of the lamp body 1 under the action of the pushing unit 24, the end of the first fan blade 21 forms an extrusion on the first extrusion cavity 23, and the air in the first extrusion cavity 23 under extrusion flows into the second fan blade 22 through the ventilation groove in the first fan blade 21. In this way, the second fan blade 22 sleeved on the first fan blade 21 starts to slide. That is, when the first fan blade 21 moves towards the side wall of the rotating ring 25 under the action of the pushing unit 24, the second fan blade 22 sleeved on the first fan blade 21 also starts to move synchronously. The second fan blade 22 slides out of the first fan blade 21. When the end of the first fan blade 21 far from the second fan blade 22 moves close to the side wall of the rotating ring 25, the first fan blade 21 is completely extended, and at this time, the second fan blade 22 sleeved on the first fan blade 21 also completely extends out of the second fan blade 22. At this time, the total length of the first fan blade 21 and the second fan blade 22 reaches the maximum. Subsequently, the rotating ring 25 drives the first fan blade 21 and the second fan blade 22 to rotate and generate an air flow, thus realizing the blowing effect.

[0042] Compared with the traditional lamp body 1 with a fan, the present invention can make the total length of the extended fans twice the length of the fans that can be extended traditionally. Of course, if more are needed, multiple second fan blades 22 can be sleeved outside the first fan blade 21 to further extend the total length of the fans, thereby expanding the blowing area of the blowing unit 2, so that the blowing area of the blowing unit 2 is expanded without changing the size of the lamp body 1 of this intelligent lighting device.

[0043] Refer to Figure 5: The first extrusion chamber 23 is jointly formed by a first corrugated sleeve 231 and a second corrugated sleeve 232. The first corrugated sleeve 231 is sleeved around the periphery of the first fan blade 21, and both ends of the first corrugated sleeve 231 are fixedly connected to the inner ring side wall of the rotating ring 25 and the end of the first fan blade 21 respectively. The second corrugated sleeve 232 is sleeved around the periphery of the first corrugated sleeve 231, and both ends of the second corrugated sleeve 232 are fixedly connected to the end of the first fan blade 21 and the inner ring side wall of the rotating ring 25 respectively.

[0044] The cavity between the first corrugated sleeve 231 and the second corrugated sleeve 232 is the first extrusion chamber 23. When the first fan blade 21 moves along the radial direction of the lamp body 1 under the action of the pushing unit 24, the end of the first fan blade 21 extrudes the first corrugated sleeve 231 and the second corrugated sleeve 232. In this way, the extrusion of the first extrusion chamber 23 is realized. The air in the first extrusion chamber 23 flows into the second fan blade 22 through the ventilation groove in the first fan blade 21 under the pressure of the end of the first fan blade 21, and pushes the second fan blade 22, realizing the effect that the second fan blade 22 slides on the first fan blade 21.

[0045] Refer to Figure 8 、 Figure 11 and Figure 12 : The pushing unit 24 includes a support disk 243 arranged at the bottom of the first fan blade 21 and a pushing disk 242 arranged at the upper part of the first fan blade 21. The axis of the support disk 243 is collinear with the axis of the pushing disk 242, and the axis of the support disk 243 is collinear with the axis of the lamp body 1. A plurality of inclined grooves 2421 are formed in the pushing disk 242. The extending direction of the inclined grooves 2421 has an included angle with the radial direction of the pushing disk 242, and the included angle is an acute angle. A guiding groove 2431 is formed in the support disk 243 along the radial direction of the support disk 243. The upper part of the first fan blade 21 extends into the inclined grooves 2421 and slidably cooperates with the inclined grooves 2421 along the extending direction of the inclined grooves 2421. The lower part of the first fan blade 21 extends into the guiding groove 2431 and slidably cooperates with the guiding groove 2431 along the extending direction of the guiding groove 2431. A first magnetic driving unit 241 for driving the pushing disk 242 to rotate is arranged on the pushing disk 242.

[0046] Refer to Figures 6 - 9 : A plurality of first attracting pieces 2411 are uniformly arranged around the axis of the pushing disk 242 at the lower part of the pushing disk 242. A plurality of first electromagnetic pieces 2412 are uniformly arranged around the axis of the support disk 243 at the upper part of the support disk 243. The first electromagnetic pieces 2412 generate magnetism when electrified and attract the first attracting pieces 2411. The first electromagnetic pieces 2412 are electrified in sequence around a fixed direction.

[0047] The first electromagnetic sheet 2412 and the first attracting sheet 2411 are arranged in a ring shape. When it is necessary to drive the driving disk 242 to rotate, the first electromagnetic sheet 2412 arranged on the driving disk 242 is sequentially energized around the axis of the driving disk 242. The first electromagnetic sheet 2412 can then attract the first attracting sheet 2411, so that the driving disk 242 arranged on the support disk 243 rotates. When the driving disk 242 rotates, the driving disk 242 pushes the first fan blade 21 through the inclined groove 2421 and moves along the radial direction of the support disk 243 under the guidance of the guiding groove 2431 of the support disk 243, ensuring that the first fan blade 21 can only move along the radial direction of the lamp body 1 when moving. When the first fan blade 21 and the second fan blade 22 are fully extended, the rotating ring 25 starts to rotate. A second magnetic force driving unit 3 is arranged on the rotating ring 25. The second magnetic force driving unit 3 includes a second attracting sheet 31 and a second electromagnetic sheet 32. The second attracting sheet 31 is uniformly and fixedly arranged at the bottom of the support disk 243 around the axis of the support disk 243, and the second electromagnetic sheet 32 is uniformly and fixedly arranged on the upper part of the lamp body 1 around the axis of the lamp body 1. When the second electromagnetic sheet 32 is energized, it attracts the second attracting sheet 31. The support disk 243 is fixedly connected to the rotating ring 25. Since the driving principles of the second magnetic force driving unit 3 and the first magnetic force driving unit 241 are the same, they will not be described in detail here. When the first fan blade 21 and the second fan blade 22 are fully extended, the second electromagnetic sheet 32 is sequentially energized and attracts the second attracting sheet 31 arranged on the support disk 243 one by one, causing the support disk 243 to rotate and drive the rotating ring 25 to rotate. In this way, it is realized that the first fan blade 21 and the second fan blade 22 can be driven by the rotating ring 25 to rotate.

[0048] Refer to Figures 1 - 4 、 Figure 12 and Figure 13 : A cleaning unit 26 is arranged on the rotating ring 25. The cleaning unit 26 includes a ring sleeve 261 arranged on the side wall of the rotating ring 25. The second fan blade 22 passes through the ring sleeve 261. A brush 262 is fixedly arranged on the inner ring side of the ring sleeve 261. The brush 262 is in sliding fit with and in contact with the surfaces of both the first fan blade 21 and the second fan blade 22.

[0049] Refer to Figure 5: A third corrugated sleeve 263 is provided at one end of the first fan blade 21 away from the side wall of the rotating ring 25. The third corrugated sleeve 263 is arranged at the end of the first fan blade 21 along the moving direction of the first fan blade 21. There is a blowing cavity 2311 between the first corrugated sleeve 231 and the second fan blade 22 in the contracted state. The third corrugated sleeve 263 forms a second extrusion cavity, and the second extrusion cavity communicates with the blowing cavity 2311. When the first fan blade 21 contracts, the second extrusion cavity is squeezed, and the air inside the second extrusion cavity is squeezed into the blowing cavity 2311 and discharged from the joint between the rotating ring 25 and the second fan blade 22.

[0050] There is a second gap between the pushing disc 242 and the end of the first fan blade 21. In the second gap, a third corrugated sleeve 263 is arranged along the extending direction of the first fan blade 21. Both ends of the third corrugated sleeve 263 are fixedly connected to the pushing disc 242 and the end of the second fan blade 22 respectively. The third corrugated sleeve 263 forms a second extrusion cavity. When the pushing unit 24 drives the first fan blade 21 to retract, the second extrusion cavity is squeezed by the first fan blade 21, and the air remaining in the second extrusion cavity flows into the blowing cavity 2311. The flowing air blows out from the inside of the rotating ring 25. The first fan blade 21 and the second fan blade 22 contact the brush 262 during the retracting process, and the brush 262 sweeps the dust on the surfaces of the first fan blade 21 and the second fan blade 22. At the same time, since the air after being squeezed by the second extrusion cavity needs to be discharged through the blowing cavity 2311, the dust will not fall into the inner ring of the rotating ring 25.

[0051] Refer to Figure 6 and Figure 8 : A collecting ring 264 is fixedly arranged around the lamp body 1. A plurality of collecting grooves 265 are formed in the collecting ring 264. The collecting grooves 265 are evenly distributed around the axis of the collecting ring 264 on the collecting ring 264. The collecting grooves 265 include an upper opening and a lower opening. The upper opening of the collecting groove 265 is larger than the lower opening of the collecting groove 265. A collecting box 266 for collecting dust is arranged at the lower part of the collecting ring 264.

[0052] The peripheral wall of the lamp body 1 is provided with threads. The collection box 266 is of an annular structure. The collection box 266 is in threaded fit with the lamp body 1, so that the upper opening of the collection groove 265 is larger than the lower opening of the collection groove 265 for two purposes. One is that when the brush 262 cleans the surfaces of the first fan blade 21 and the second fan blade 22, dust is more likely to fall into the collection groove 265. The other is that when the first fan blade 21 and the second fan blade 22 are in a rotating state, the airflow generated by the first fan blade 21 and the second fan blade 22 will not blow up the dust in the collection box 266 when passing through the collection groove 265. After the user has used it for a period of time, the collection box 266 can be unscrewed from the lamp body 1 to complete the cleaning of the collection box 266.

[0053] Refer to Figure 4 、 Figure 7 and Figure 9 : A groove 28 is formed in the upper part of the support disk 243. A locking unit 27 is arranged in the groove 28. The locking unit 27 includes an electromagnet 274 arranged at the bottom of the groove 28. A spring 273 is vertically arranged above the electromagnet 274. A locking block 272 is arranged above the spring 273. After the electromagnet 274 is powered on, it can attract the locking block 272. The locking block 272 is in sliding fit and key connection with the groove 28. A locking groove 271 is vertically formed at the bottom of the push disk 242. The locking block 272 is in snap fit with the locking groove 271. The cross section of the locking block 272 is of a non-circular structure, and the cross-sectional shape of the locking groove 271 is mutually compatible with the cross-sectional shape of the locking block 272.

[0054] The locking block 272 is in snap fit with the locking groove 271 when the first fan blade 21 and the second fan blade 22 are in a fully retracted or fully extended state. When the push disk 242 needs to rotate, the electromagnet 274 is powered on to attract the locking block 272, so that the locking block 272 slides out of the locking groove 271. In this way, the push disk 242 can rotate normally. After the push disk 242 has completed rotation, the electromagnet 274 is powered off, and the spring 273 pushes the locking block 272 to slide into the locking groove 271 and locks the push disk 242. At this time, the push disk 242 can rotate synchronously with the support disk 243.

[0055] Refer to Figure 8 、 Figure 9 、 Figure 11 and Figure 12 : The mounting plate 4 is arranged above the pushing unit 24. An extension rod 41 is fixedly arranged vertically at the lower part of the mounting plate 4. Threads are formed on the side wall at the bottom of the extension rod 41. The extension rod 41 penetrates through the push disk 242 and the support disk 243 vertically from top to bottom and is in threaded fit with the upper part of the lamp body 1.

[0056] During installation, align the lamp body 1 provided with the blowing unit 2 with the extension rod 41 located below the mounting plate 4. Then lift the mounting plate 4 provided with the blowing unit 2. The extension rod 41 successively penetrates the pushing disc 242 and the supporting disc 243 from top to bottom. Threads are provided on the bottom side wall of the extension rod 41. After the upper part of the lamp body 1 contacts the bottom of the extension rod 41, rotate the lamp body 1 so that the lamp body 1 is in threaded engagement with the extension rod 41, thus completing the installation. A screw hole is also provided at the bottom of the mounting plate 4. Before installation, first install the mounting plate 4 on the roof through the screw hole, and then carry out subsequent installation. The rotation direction of the rotating ring 25 is the same as the rotation direction of the thread on the extension rod 41, so that it can be ensured that the lamp body 1 will not become loose from the extension rod 41 when the rotating ring 25 rotates.

[0057] Refer to Figures 1 - 13 : The present invention also relates to a turbulent flow type intelligent lighting method based on the wifimesh technology, and adopts a turbulent flow type intelligent lighting device based on the wifimesh technology. The specific steps are as follows:

[0058] S(1). When blowing is required, the pushing unit 24 pushes the first fan blade 21 to move along the radial direction of the lamp body 1 and slide out from the side wall of the rotating ring 25. During the process of the first fan blade 21 sliding out from the side wall of the rotating ring 25, the first fan blade 21 squeezes the first extrusion cavity 23. The air in the first extrusion cavity 23 flows into the interior of the second fan blade 22 through the ventilation groove in the first fan blade 21, and the second fan blade 22 synchronously extends on the first fan blade 21 when the first fan blade 21 slides out.

[0059] S(2). When the pushing unit 24 completely pushes out the first fan blade 21, the second fan blade 22 slides to the end of the first fan blade 21 away from the rotating ring 25. At this time, the total length of the first fan blade 21 and the second fan blade 22 is the longest. Then the rotating ring 25 starts to rotate around the lamp body 1.

[0060] S(3). After the rotation is completed, the pushing unit 24 drives the first fan blade 21 to retract into the rotating ring 25. The first extrusion cavity 23 stretches, and the air in the second fan blade 22 flows into the first extrusion cavity 23 through the ventilation groove. The second fan blade 22 resets to the initial state on the first fan blade 21.

[0061] Working principle: After the blowing unit 2 is started, the pushing unit 24 starts first, and pushes the first fan blade 21 located on one side of the inner ring of the rotating ring 25, so that the first fan blade 21 drives the second fan blade 22 sleeved on the periphery of the first fan blade 21 to move along the radial direction of the lamp body 1. The second fan blade 22 is in sliding fit with the rotating ring 25 along the radial direction of the lamp body 1 under the drive of the first fan blade 21. The first fan blade 21 drives the second fan blade 22 to gradually extend. Since there is a first gap between the end of the first fan blade 21 and the inner ring of the rotating ring 25, and a first extrusion cavity 23 is arranged on the first gap. When the first fan blade 21 moves along the radial direction of the lamp body 1 under the action of the pushing unit 24, the end of the first fan blade 21 forms an extrusion on the first extrusion cavity 23, and the air in the first extrusion cavity 23 being extruded flows into the second fan blade 22 through the ventilation groove in the first fan blade 21. In this way, the second fan blade 22 sleeved on the first fan blade 21 starts to slide. That is, when the first fan blade 21 moves towards the side wall of the rotating ring 25 under the action of the pushing unit 24, the second fan blade 22 sleeved on the first fan blade 21 also starts to move synchronously. The second fan blade 22 slides out from the first fan blade 21. When the end of the first fan blade 21 far from the second fan blade 22 moves close to the side wall of the rotating ring 25, the first fan blade 21 is fully extended, and at this time, the second fan blade 22 sleeved on the first fan blade 21 also completely extends from the second fan blade 22. At this time, the total length of the first fan blade 21 and the second fan blade 22 reaches the maximum, and compared with the traditional lamp body 1 with a fan, the blowing area of the blowing unit 2 is enlarged.

[0062] After the blowing is completed, the first fan blade 21 retracts under the action of the pushing unit 24, the second extrusion cavity is squeezed by the first fan blade 21, and the air in the second extrusion cavity is discharged from the blowing cavity 2311. In this way, the dust cleaned by the brush 262 will not enter the rotating ring 25 along with the first fan blade 21 and the second fan blade 22.

[0063] The above embodiments only represent one or several implementation manners of the present invention, and the description is relatively specific and detailed, but it cannot be understood as a limitation on the scope of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the appended claims.
