Description

Technical Field

[0001] This utility model belongs to the technical field of lighting devices, specifically relating to a dust collection structure and a bladeless fan lamp. Background Technology

[0002] Ceiling fan lights, which combine lighting and air circulation functions, have gained market acceptance and widespread acclaim in recent years. Bladeless ceiling fan lights, as a branch of this category, are particularly favored by the home decoration industry due to their consistent overall design.

[0003] Bladeless ceiling fans are typically fixed to the indoor ceiling. Compared to traditional ceiling fans, cleaning their internal dust collection is more complicated, sometimes requiring disassembly of the light fixture for cleaning, increasing the difficulty of later maintenance. If dust is not removed in time, it will affect the fan's airflow and the light fixture's heat dissipation, which in severe cases can reduce the lifespan and even cause short circuits.

[0004] Existing solutions often involve installing a filter at the air inlet to trap dust, followed by periodic cleaning of the filter. While this alleviates dust accumulation inside bladeless fan lights, it increases inlet resistance, affecting airflow efficiency. Another common dust collection method utilizes electrostatic adsorption to concentrate dust in easily cleaned areas, which can then be cleaned periodically. However, electrostatic adsorption can charge surrounding plastic materials, causing charge buildup on the inner walls of the duct and leading to dust accumulation in other areas. Furthermore, in autumn and winter, fan lights are typically only used for illumination, and the low humidity at this time makes it easy for static electricity to accumulate around the lampshade, resulting in severe dust accumulation on the inner walls of the duct after the seasonal change. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a dust collection structure that uses a vibrating component to shake off the accumulated dust in the air duct, while the detachable dust collection component collects the blown dust without affecting the airflow effect of the fan light. This simplifies the daily cleaning of bladeless fan lights while ensuring both dust removal and collection effects.

[0006] The technical effect to be achieved by this utility model is realized through the following technical solution: In a first aspect, this utility model provides a dust collection structure, comprising: The housing assembly includes a first housing and a second housing, wherein the first housing is disposed inside the second housing and the first housing surrounds to form an installation space; A lamp housing is disposed within the installation space, and an air duct is formed between the lamp housing and the first housing. A fan wheel is provided in the air duct, and the lower end of the air duct is an air outlet. A dust collection component, adjacent to the air outlet, is detachably connected to the second housing; and A vibrating element is disposed on the side wall of the first housing facing the air duct; The dust collection component includes a collecting part, a fixing part, and a filter element, with the fixing part located at the upper end of the collecting part.

[0007] In some implementations, the fixing part is snapped into the second housing, the collecting part is provided with a dust collection groove and a through hole, the through hole is located at the bottom of the dust collection groove, and the filter is located above the through hole.

[0008] In some implementations, the cross-section of the collecting part is U-shaped, the dust collection trough is provided with a dust collection opening, and the dust collection opening is connected to the air outlet.

[0009] In some implementations, the collecting part includes a first perimeter and a second perimeter disposed on the inner and outer sides respectively, the first perimeter being close to the lamp housing, and the upper end of the first perimeter being aligned with the lower end of the first housing.

[0010] In some implementations, the second perimeter abuts against the lower end of the second housing.

[0011] In some implementations, the second housing is provided with a boss that extends from the lower end of the second housing toward the first housing; the fixing part is provided with a slot that is rotatably engaged with the boss.

[0012] In some implementations, the boss and the slot are provided in multiple sets, and the central angle of each set of the boss and the slot is not less than 50°.

[0013] In some implementations, the first housing has a mounting position on the side wall facing the air duct, and the vibrating element is fixed to the mounting position; the dust collection element also includes a dust collection sensor, which is disposed in the dust collection groove.

[0014] In some implementations, the surfaces of the first housing and the lamp housing facing the air duct are the air duct wall, and the roughness height value of the air duct wall is ks. Then ks satisfies the relationship: 1μm≤ks≤5μm.

[0015] Secondly, this utility model provides a bladeless fan light, including: a fan, an air inlet grille, a light source assembly, and the aforementioned dust collection structure; The fan is disposed within the installation space, and the lamp housing is fixed to the installation space by the fan. The fan includes a fan wheel, which is disposed in the air duct. The air duct has an air inlet, and the air inlet grille is disposed on the top of the second housing and located outside the air inlet. The lamp housing has a light-emitting cavity, and the light source assembly is disposed within the light-emitting cavity.

[0016] In summary, this utility model has at least the following advantages: 1. The dust collection structure provided by this utility model shakes the accumulated dust in the air duct into the air duct by vibrating the inner wall of the first housing through the vibrating component. Then, the dust is driven by the impeller to flow towards the air outlet. The dust collection component is adjacent to the air outlet. Most of the shaken dust enters the collection part to achieve the purpose of dust collection. During daily maintenance, it is only necessary to start the vibrating component and clean the dust collection component, which effectively simplifies the daily cleaning work of bladeless fan lights.

[0017] 2. The dust collection structure provided by this utility model has the dust collection component adjacent to the air outlet. The airflow generated by the large number of impellers is still blown outward through the air outlet. While simplifying the cleaning work and ensuring the dust removal and collection effect, the dust collection structure has basically no impact on the air output performance of the bladeless fan light.

[0018] 3. The bladeless fan light provided by this utility model simplifies daily dust cleaning by adopting a dust collection structure, and its own airflow has minimal impact. Only the dust collection and vibration components are added; no other functional modules are needed to fulfill the dust cleaning and collection functions. Therefore, the increased cost of adopting the dust collection structure in the bladeless fan light is limited. Furthermore, the dust collection structure does not affect the overall appearance and lighting performance of the light, making it more competitive in the market. Attached Figure Description

[0029] To facilitate understanding of this utility model, a more comprehensive description will be given below with reference to the accompanying drawings and specific embodiments. The drawings illustrate preferred embodiments of this utility model. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.

Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first," "second," and "third," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] Example 1: Please see Figures 1-5 This embodiment provides a dust collection structure 100, which is mainly installed in a bladeless fan light and used for dust cleaning and collection. The dust collection structure 100 includes a housing assembly 1, a lamp housing 2, a dust collection component 4, and a vibrating component 5. Specifically, the housing assembly 1 includes a first housing 11 and a second housing 12. The second housing 12 forms the appearance of the bladeless fan light, providing support and protection for the entire bladeless fan light. The first housing 11 is located inside the second housing 12, forming an installation space 13. The lamp housing 2 is disposed within the installation space 13, used to accommodate and fix the light source components and optical components in the bladeless fan light. An air duct 3 is formed between the lamp housing 2 and the first housing 11. A fan wheel 61 is provided in the air duct 3, generating airflow and driving the airflow unidirectionally within the air duct 3. The lower end of the air duct 3 is an air outlet 31, from which the airflow leaves the bladeless fan light. The dust collection component 4 is adjacent to the air outlet 31 and is detachably connected to the second housing 12. The vibrating element 5 is disposed on the side wall of the first housing 11 facing the air duct 3.

[0034] More specifically, the dust collection component 4 includes a collecting part 41, a fixing part 42, and a filter element 43. The fixing part 42 is disposed at the upper end of the collecting part 41. The fixing part 42 cooperates with the second housing 12 to achieve a detachable connection between the dust collection component 4 and the second housing 12. The collecting part 41 is used to collect dust blown out from the air outlet 31, and the filter element 43 is disposed inside the collecting part 41 to facilitate subsequent cleaning of the dust collection component 4.

[0035] When the bladeless fan light needs internal cleaning, the speed of the impeller 61 can be adjusted to the maximum to increase the airflow inside the duct 3. Then, the vibrating element 5, which can be a motor with vibration function, is activated. The vibrating element 5 vibrates the inner wall of the first housing 11, shaking the accumulated dust in the duct 3 and dislodging it into the duct 3, where it is carried away by the high-speed airflow. When the dusty airflow rushes towards the outlet 31, the airflow does not leave directly from the outlet 31, but rather partially tilts into the collection section 41 of the dust collector 4, and the dust also follows, thus achieving dust collection.

[0036] Under normal circumstances, the cross-section of the air duct 3 between the first housing 11 and the lamp housing 2 gradually decreases as it approaches the air outlet 31. Therefore, the airflow in the air duct 3 reaches its maximum at the air outlet 31. At the same time, a large amount of dust will also accumulate at the air outlet 31. After being collided and guided by the lamp cover and the first housing 11, most of the dust will enter the collection section 41 and fall onto the filter 43 set in the collection section 41.

[0037] After the impeller 61 has been running at high speed for a period of time, the vibrating component 5 and the impeller 61 are turned off. The user can then disassemble and clean the dust collection component 4. After cleaning, the dust collection component 4 is then reassembled with the second housing 12, thus completing the daily dust removal work.

[0038] With the dust collection structure 100 provided in this embodiment, routine maintenance only requires activating the vibrator 5 and cleaning the dust collection component 4, significantly simplifying the daily cleaning of the bladeless fan light. While simplifying the cleaning process and ensuring dust removal and collection effects, the dust collection component 4 is only adjacent to the air outlet 31, rather than completely blocking it, so it has virtually no impact on the airflow effect of the air outlet 31. A large amount of airflow generated by the impeller 61 is still blown outward through the air outlet 31. Compared to directly setting a filter screen at the air inlet 32 ​​or the air outlet 31 for dust collection, this dust collection structure 100 ensures that the performance of the bladeless fan light is not affected.

[0039] Furthermore, the fixing part 42 is snapped and fixed to the second housing 12. The collecting part 41 is provided with a dust collection groove 411 and a through hole 412. The through hole 412 is located at the bottom of the dust collection groove 411, and the filter sheet 43 is located above the through hole 412. Please... Figures 1-3 Based on the above Figure 4 The area of ​​the through hole 412 occupies a large portion of the bottom area of ​​the collection section 41. When the airflow carries dust into the dust collection tank 411, the airflow will flow out through the through hole 412 due to inertia. The filter plate 43, which is set above the through hole 412, filters the dust and leaves it in the dust collection tank 411, waiting for subsequent cleaning. However, if the through hole 412 is not provided or the area of ​​the through hole 412 is insufficient, the dust collection tank 411 will have a certain degree of airtightness. Subsequent airflow may be forced not to enter due to high internal resistance, or the airflow entering the collection section 41 may stir up the dust that has settled on the filter plate 43. Both of these situations will affect the collection effect of the dust collection component 4.

[0040] Continue reading Figures 1-4Furthermore, the collecting section 41 has a U-shaped cross-section, and the dust collection groove 411 is provided with a dust collection opening 44, which is connected to the air outlet 31. The airflow from the air outlet 31 enters the dust collection opening 44 at an angle, then flows out through the through hole 412 after passing through the dust collection groove 411, while dust accumulates inside the U-shaped collecting groove. It should be noted that as the amount of dust collected gradually increases, the resistance of the airflow passing through the collecting section 41 will also gradually increase. If the accumulated dust is not cleaned in time, the effect is similar to the aforementioned situation where the through hole 412 is not provided or the area of ​​the through hole 412 is too small, both of which are detrimental to the dust collection work of the dust collection component 4.

[0041] In some embodiments, the collecting part 41 includes a first perimeter 413 and a second perimeter 414 disposed on the inner and outer sides respectively. The first perimeter 413 is close to the lamp housing 2, and the upper end of the first perimeter 413 is aligned with the lower end of the first housing 11. The alignment of the first perimeter 413 with the lower end of the first housing 11 ensures that the airflow mainly flowing outward from the air outlet 31 is not affected, thus guaranteeing the airflow volume and speed. When the airflow blows out from the air duct 3, since the airflow blows from the middle to both sides, the dust will also concentrate near the end of the first housing 11 and be blown out. In practice, most of the dust will be blown by the airflow into the gap between the end of the first housing 11 and the first perimeter 413, thereby entering the dust collection opening 44, achieving efficient dust collection. On the outer side, the second perimeter 414 abuts against the lower end of the second housing 12 and is aligned with the lower end of the second housing 12. This arrangement not only ensures the stable connection of the dust collection component 4 to the second housing 12, but also improves the overall appearance of the bladeless fan light. In some embodiments, the second perimeter 414 may be aligned only with the lower end of the second housing 12, without abutting against it.

[0042] In this embodiment, the second housing 12 is provided with a boss 121, which extends from the lower end of the second housing 12 toward the first housing 11. The fixing part 42 of the dust collection component 4 is provided with a slot 421, which is rotatably engaged with the boss 121 of the second housing 12. Since most bladeless fan lights currently adopt a symmetrical circular structure, the snap-fit ​​structure of the boss 121 and the slot 421 facilitates the positioning and locking of the dust collection component 4 and the housing assembly 1 during installation and disassembly, reducing the installation difficulty for users.

[0043] In some embodiments, to improve the firmness of the screw fastening between the boss 121 and the slot 421, multiple sets of bosses 121 and slots 421 are provided, and are evenly distributed along the lower end of the second housing 12 and the circumference of the fixing part 42, respectively, and the central angle of each set of bosses 121 and slots 421 is not less than 50°. Figures 4-5As shown, in this example, the boss 121 and the slot 421 are set in three sets, and the central angle of each set is 50°. If the number is too large or the central angle is too small, it will affect the connection stability of the dust collection component 4. Of course, in other embodiments, the boss 121 and the slot 421 can also be set in two sets, and the central angle of each set is 70°. However, during installation and disassembly, the angle of rotation displacement required for the dust collection component 4 is larger than that in this embodiment, and the time required for disassembly and installation will also be longer.

[0044] In summary, the dust collection structure provided in this embodiment shakes the accumulated dust in the air duct into the air duct by vibrating the inner wall of the first housing. The dust is then driven by the impeller to flow towards the air outlet. The dust collection component is adjacent to the air outlet, and most of the shaken dust enters the collection part to achieve the purpose of dust collection. During daily maintenance, it is only necessary to start the vibrating component and clean the dust collection component, which simplifies the daily cleaning work of the bladeless fan light.

[0045] Secondly, in the dust collection structure provided in this embodiment, the dust collection component is adjacent to the air outlet, and the airflow generated by a large number of impellers still flows outward through the air outlet. While simplifying the cleaning work and ensuring the dust removal and collection effect, the dust collection structure has virtually no impact on the air output performance of the bladeless fan light.

[0046] Example 2: Please Figures 1-5 Based on the above Figures 6-8 This embodiment provides a dust collection structure 100, which is an adjustment and optimization based on Embodiment 1. Unlike Embodiment 1, the first housing 11 has a mounting position 111 on its side wall facing the air duct 3, and the vibrating element 5 is fixed to the mounting position 111. To facilitate wiring of the vibrating element 5, the mounting position 111 is designed to penetrate the first housing 11. The vibrating element 5 can be installed in the mounting position 111 using adhesive or similar materials, and its cable connects to the external circuit from the side away from the air duct 3. Similarly, in some embodiments, a mounting position 111 can also be provided on the lamp housing 2 for mounting the vibrating element 5.

[0047] Furthermore, the dust collection component 4 also includes a dust collection sensor 45, which is disposed within the dust collection tank 411. Considering the limited capacity of the dust collection tank 411 in the dust collection component 4, the dust collection sensor 45 can provide relevant prompts to the user, allowing the user to clean it in a timely manner and keeping the dust collection component 4 in optimal working condition.

[0048] The surface roughness height of the two sides of the air duct 3, as one of the evaluation criteria for material surface roughness, determines the ease with which dust adheres and detaches, thus affecting the dust removal and collection effect. Furthermore, the surfaces of the first housing 11 and the lamp housing 2 facing the air duct 3 are the air duct wall 112, and the surface roughness height of the air duct wall 112 is ks. To improve the dust collection efficiency of the dust collection component 4, ks needs to satisfy the relationship: 1μm≤ks≤5μm.

[0049] To better analyze the impact of the duct wall 112 on dust, we used the roughness height value ks on the duct wall 112 as a variable in the simulation experiment. Figure 8 A simplified schematic diagram of the dust removal structure is provided, which serves as the basis for simulation. Experimental parameters were set as follows: wind speed of 10 m / s; dust particles with a diameter uniformly distributed within the range of 10–100 micrometers (10–100 micrometers represents the diameter range of dust particles visible to the naked eye in an indoor environment); and the surface roughness height value ks of the duct wall 112 was set to 0–5 μm (a roughness height value of ks of 0 μm indicates that the duct wall 112 is smooth, serving as a comparative example). The simulation results are shown in the table below.

[0050] Table 1. Dust particle capture rate of the dust collection device when the duct wall roughness height is different.

[0051] As can be seen from the table, the roughness of the duct wall 112 is beneficial to the final dust particle capture rate. The data in the table shows that under the above experimental conditions, the dust particle capture rate of the dust collection component 4 is the highest when the roughness height value ks is 4μm.

[0052] It should be noted that the above simulation experiment was conducted only for a wind speed of 10 m / s. Changes in wind speed may affect the final values. That is, when the wind speed is no longer 10 m / s, the optimal roughness height value ks is not necessarily 4 μm. Furthermore, the roughness height value ks can be further refined, for example, by using values ​​of 3.5 μm or 4.12 μm for the above simulation experiment. The related descriptions and analyses will not be detailed here.

[0053] Example 3: Please Figures 1-8 Based on the above Figure 9This embodiment provides a bladeless fan light 200, including a fan 6, an air inlet grille 7, a light source assembly 8, and a dust collection structure 100 as described in Embodiment 1 or Embodiment 2. The fan 6, as the main power structure of the bladeless fan light 200, is disposed within the installation space 13. The lamp housing 2 is fixed to the installation space 13 by the fan 6. The fan 6 generally includes a fan wheel 61 and a motor 62. The fan wheel 61 is disposed in the air duct 3, and the motor 62 is disposed between the outer housing assembly 1 and the lamp housing 2. The air duct 3 has an air inlet 32, and the air inlet grille 7 is disposed on the top of the second housing 12 and located outside the air inlet 32. The lamp housing 2 has a light emission cavity 21, and the light source assembly 8 is disposed within the light emission cavity 21.

[0054] During normal use, the light source assembly 8 provides illumination, while the fan 6 generates airflow; their operation is independent of each other. The motor 62 of the fan 6 drives the impeller 61 to rotate, and airflow enters the duct 3 through the air inlet 32. The air inlet grille 7, located at the air inlet 32, protects the duct 3 from larger foreign objects, preventing the impeller 61 from colliding with these objects and damaging the internal structure. Of course, in some embodiments, a smaller mesh filter can also be installed on the air inlet grille 7 for coarse filtration.

[0055] When the airflow enters the air duct 3, it flows out from the air outlet 31 along the direction of the air duct 3. Since the air duct 3 is generally designed with a gradually decreasing cross-section, the airflow velocity reaches its maximum at the air outlet 31, thus providing a strong airflow effect to the space below the bladeless fan light 200. At this time, the airflow generated by the impeller 61 flows from the middle of the bladeless fan light 200 to the surrounding area, and the dust also gathers at the lower end of the first housing 11 with the airflow, and then enters the collection section 41 along the airflow direction to complete the daily dust collection work.

[0056] When it is necessary to centrally process the accumulated dust in the air duct 3, the fan 6 is turned to its maximum speed, and the vibrator 5 is activated to shake off the accumulated dust. The strong airflow will accelerate the further accumulation of dust at the lower end of the first housing 11, where it will be collected by the collection unit 41. After completing the above dust removal work, the fan 6 is turned off, and the dust collection unit 4 is removed for cleaning. The cleaned dust collection unit 4 is then reinstalled on the first housing 11, thus completing a full dust removal and maintenance operation.

[0057] By adopting the dust collection structure 100 of Embodiment 1 or Embodiment 2, the dust removal process of the bladeless fan light 200 in this embodiment becomes simple and easy to operate. The added dust collection component 4 and vibration component 5 have little impact on the air output effect, and the purpose of dust removal and collection can be achieved without increasing costs significantly. Of course, the inclusion of the dust collection structure 100 does not affect the overall design and lighting performance of the bladeless fan light 200. Compared with the existing methods of using a filter screen at the air inlet 32 ​​and electrostatic dust collection, it has greater market potential.

[0058] Considering that static electricity will still be generated when the lamp is lit even if the fan 6 is not turned on, thus attracting a large amount of dust into the first housing 11 and the lamp housing 2, it is recommended that if the fan function is not used for a long time, the dust collection should be cleaned in the manner described above before the first use. This can effectively clean the dust inside the bladeless fan lamp 200 and ensure that the air duct 3 and the dust collection component 4 are in the best working condition when used later.

[0059] In summary, the bladeless fan light provided in this embodiment adopts a dust collection structure with automatic dust collection function, which simplifies daily dust cleaning work and has minimal impact from its own airflow. By simply adding a dust collection component and a vibration component, the dust cleaning and collection functions can be met without adding other functional modules, without affecting the overall appearance and lighting performance of the light, making it more competitive in the market.

[0060] The above description is merely an example and illustration of the structure of this utility model, and while the description is quite specific and detailed, it should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these obvious substitutions all fall within the protection scope of this utility model.
