Description

Technical Field

[0001] This utility model relates to the field of household appliance technology, and in particular to a fan light. Background Technology

[0002] Fan lights, as household appliances that combine ventilation and lighting functions, are widely used in homes, offices, and other places because they save space. Currently, the mainstream fan lights on the market mainly include concealed fan lights (the fan blades unfold when working and retract when not working), open-blade fan lights (the fan blades are always exposed), and small-blade oscillating fan lights. The common feature of these products is that the fan blades are directly exposed when working, which can easily cause safety concerns for users, especially in spaces with low installation heights.

[0003] To address the issue of exposed fan blades, internal flow channel fan lights have emerged. These lights guide airflow through an internal channel within the cavity, concealing the fan blades to improve safety. However, existing internal flow channel fan lights have significant drawbacks: because air must pass through the internal channel, the channel diameter is limited, resulting in a smaller airflow and lower energy efficiency; furthermore, existing internal flow channel fan lights lack air filtration capabilities, failing to meet users' indoor air quality requirements, and some structural designs still have room for improvement.

[0004] In view of this, it is indeed necessary to improve the existing fan lights in order to solve the above problems. Utility Model Content

[0019] Optionally, the lower casing has multiple spaced guide blocks on the side facing the impeller. The guide blocks protrude towards the impeller to form an air outlet channel between two adjacent guide blocks. The air outlet channel connects the ventilation cavity and the air outlet. A decorative cover is provided on the side of the guide blocks away from the impeller.

[0020] Optionally, the outer edge of the guide ring has an annular overlapping portion on the side facing the guide ring, and the air inlet side of the guide ring has a stepped portion that engages with the overlapping portion.

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] It should be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0049] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0050] like Figures 1-3 As shown, this utility model provides a fan light 100. The fan light 100 includes a flow channel assembly 200, a fan assembly 300, a housing 400, a flow guide ring 410, and a filter assembly 500.

[0051] like Figures 3-5 As shown, the flow channel assembly 200 includes an upper shell 210 and a lower shell 220, which are fixed together by screws. The upper shell 210 has an air inlet 2101, and an air cavity 230 is formed between the upper shell 210 and the lower shell 220. An air outlet 2201 is formed on the outer periphery of the lower shell 220. The air inlet 2101, the air cavity 230, and the air outlet 2201 are interconnected to form a complete internal flow channel airflow circulation, ensuring unobstructed airflow path and improving ventilation efficiency.

[0052] The fan assembly 300 is housed inside the air cavity 230 and includes a motor assembly 310 and an impeller 320 mounted on the lower housing 220. The motor assembly 310 is connected to the impeller 320 to drive the impeller 320 to rotate, thereby generating centrifugal force to draw air in from the air inlet 2101 and discharge it through the air outlet 2201, thus achieving air circulation.

[0053] The outer casing 400 covers the outside of the flow channel assembly 200 and is fixedly connected to the upper casing 210. A guide ring 410 is located on the outer casing 400 at the position corresponding to the air inlet 2101. The outer casing 400 not only protects the internal structure of the flow channel assembly 200 from dust and foreign objects, extending its service life, but also enhances the overall structural stability of the fan light 100 through its fixation to the upper casing 210. Simultaneously, the outer casing 400 integrates the guide ring 410 at the position corresponding to the air inlet 2101, resulting in a cleaner appearance and improved product aesthetics.

[0054] like Figures 4-5 As shown, the guide ring 410 is arranged around the outside of the air inlet 2101, and its interior forms an air intake channel 4101 that communicates with the air inlet 2101. This guides the airflow into the air inlet 2101 in an orderly manner, improving air intake efficiency. When the impeller 320 rotates, the intake air forms a rotating wind field within the air intake channel 4101, which enhances dynamic pressure and increases wind speed and air volume.

[0055] Preferably, the diameter of the air inlet channel 4101 is larger than the diameter of the air inlet 2101, so as to ensure that the amount of air entering the air inlet channel 4101 is sufficient and to avoid limiting the air volume due to insufficient air intake.

[0056] The ratio of the height of the guide ring 410 to the diameter of the air inlet 2101 is in the range of 0.2 to 0.3. Preferably, the height of the guide ring 410 is one-quarter of the diameter of the air inlet 2101, which can increase the air volume by 15% to 25%.

[0057] Preferably, the guide ring 410 is tapered, and the diameter of the air inlet channel 4101 gradually decreases from the side away from the air inlet 2101 to the air inlet 2101. The tapered structure is more conducive to air convergence, reduces airflow resistance in the air inlet channel 4101, further improves air intake efficiency, and enhances the product's aesthetics.

[0058] like Figure 5As shown, the lower casing 220 has multiple spaced guide blocks 2202 on the side facing the impeller 320. The guide blocks 2202 protrude towards the impeller 320 of the fan assembly 300 to form an air outlet channel 2203 between two adjacent guide blocks 2202. The air outlet channel 2203 connects the ventilation cavity 230 and the air outlet 2201. The guide blocks 2202 can guide the airflow in the ventilation cavity 230 into the air outlet channel 2203 in an orderly manner, avoiding airflow loss caused by airflow turbulence. Furthermore, by adjusting the matching degree between the guide blocks 2202 and the rotation direction of the impeller 320, the air supply range can be expanded and the spatial air circulation effect can be improved.

[0059] A decorative cover 2204 is provided on the side of the guide block 2202 away from the impeller 320, which can cover the screws and other connecting structures in the guide block 2202, and improve the appearance of the fan light 100.

[0060] Preferred, such as Figure 3 As shown, the lower shell 220 is also provided with a reinforcing plate 2205 fixed thereto, making the structure of the fan light 100 more robust.

[0061] like Figures 6-7 As shown, the filter assembly 500 is arranged around the outside of the guide ring 410 and located in the air intake path of the air intake channel 4101. It can filter the air entering the fan lamp 100 and improve indoor air quality. The filter assembly 500 includes a filter element holder 510 and a filter element 520. External airflow enters the air intake channel 4101 after passing through the receiving portion 5101 of the filter element holder 510 and the filter element 520.

[0062] Filter element 520 can filter dust, particulate matter and other impurities in the air, achieving air purification and improving indoor air quality. Filter element 520 is housed in the receiving part 5101, meaning that filter element 520 is a removable design, making it easy for users to replace and maintain.

[0063] like Figure 9 As shown, the filter element holder 510 includes a receiving portion 5101 and an outer edge portion 5102 arranged vertically along the height direction of the guide ring 410. The outer edge portion 5102 surrounds the outer periphery of the guide ring 410 and is engaged with the guide ring 410.

[0064] like Figures 7-8As shown, the outer edge 5102 has an annular overlapping portion 5121 on the side facing the airflow guide ring 410. Correspondingly, the airflow guide ring 410 has a stepped portion 4102 on the airflow inlet side that engages with the overlapping portion 5121. The diameter of the overlapping portion 5121 is equal to the maximum inner diameter of the airflow inlet channel 4101. The engaging connection between the overlapping portion 5121 and the stepped portion 4102 makes the connection between the filter element seat 510 and the airflow guide ring 410 tighter. Furthermore, since the diameter of the overlapping portion 5121 matches the maximum inner diameter of the airflow inlet channel 4101, it avoids increased airflow resistance due to size mismatch. Simultaneously, this engaging structure further prevents unfiltered air from entering the airflow inlet channel 4101 through gaps, ensuring filtration and airflow efficiency.

[0065] like Figures 9-10 As shown, the filter element holder 510 includes a first filter element holder 5103 and a second filter element holder 5104 connected by a snap-fit ​​structure 530. The snap-fit ​​structure 530 includes an insertion part 5301, a first snap-fit ​​part 5302 disposed on the first filter element holder 5103, and a second snap-fit ​​part 5303 disposed on the second filter element holder 5104. The first snap-fit ​​part 5302 and the second snap-fit ​​part 5303 are respectively inserted into the insertion part 5301 and engaged with the insertion part 5301. The snap-fit ​​structure 530 allows for quick assembly of the first filter element holder 5103 and the second filter element holder 5104. The engagement connection between the outer edge 5102 and the guide ring 410 does not require screws, simplifying the installation process. Furthermore, the snap-fit ​​structure 530 is hidden above the filter assembly 500, and is not visible after the fan light 100 is installed, thus not affecting the product's aesthetics.

[0066] In this embodiment, the first latching part 5302 and the second latching part 5303 are L-shaped latches, and the insertion part 5301 is a fixing latch. After the first filter element seat 5103 and the second filter element seat 5104 are joined together, the fixing latch is inserted into the two L-shaped latches. After the latches are in place, pressing down on the fixing latches will lock the first filter element seat 5103 and the second filter element seat 5104. Similarly, to remove the filter element seat 510, simply pull the fixing latch upwards and then pull it out from the L-shaped latches. In other embodiments, the latching structure 530 can also be a combination of mechanical connection structures such as hook type, magnetic type, rotary type, slider type, or expansion type, as long as it can achieve quick and detachable locking of the first filter element seat 5103 and the second filter element seat 5104 together.

[0067] like Figure 3As shown, the fan light 100 also includes a bracket assembly 600, a hanging rod assembly 700, a lighting assembly 800, an electrical control assembly 900, and a cover 1000. The bracket assembly 600 is fixed to the mounting surface to secure the entire fan light 100. One end of the hanging rod assembly 700 is connected to the bracket assembly 600, and the other end passes through the filter assembly 500 and the guide ring 410 to connect to the motor shaft of the motor assembly 310. The lighting assembly 800 is connected to the lower housing 220 to provide lighting functionality, combining with the fan function to enhance the practicality of the fan light 100. The electrical control assembly 900 is connected to the lower housing 220 and is configured to control the operation of the lighting assembly 800 and the fan assembly 300. The cover 1000 is connected to the lower housing 220 to cover the lighting assembly 800 and the electrical control assembly 900, preventing the internal structure from being exposed and improving aesthetics. A receiving space is formed between the mask 1000 and the lower shell 220. The lighting component 800 and the electronic control component 900 are both received in the receiving space, and the lighting component 800 is arranged around the outside of the electronic control component 900, which optimizes the space layout and reduces the volume occupied.

[0068] When installing the fan light 100, first fix the impeller 320 to the motor, fix the reinforcing plate 2205 and decorative cover 2204 to the lower housing 220, and fix the electronic control component 900 and lighting component 800 in the recessed receiving space of the lower housing 220. Install the shaft sleeve assembly on the motor shaft, and fix the lower housing 220 to the motor shaft with a nut assembly. The upper end of the motor shaft is connected to the hanging rod assembly 700. Next, assemble the lower housing 220 with the upper housing 210 and secure it with screws. The power cord passes through the motor shaft and connects to the electronic control component 900. Simultaneously, connect the leads of the lighting component 800 and the motor assembly 310 to the electronic control component 900, and fix the electronic control cover of the electronic control component 900 to the lower housing 220 with screws. Assemble the outer housing 400 with the flow channel assembly 200 and secure it to the upper housing 210 with screws. Finally, assemble the faceplate 1000 with the lower housing 220. Then, the two filter elements 520 are placed into the first filter element holder 5103 and the second filter element holder 5104 respectively. The first filter element holder 5103 and the second filter element holder 5104 are fastened together along the hanging rod, so that the filter assembly 500 is engaged with the guide ring 410. Then, the first filter element holder 5103 and the second filter element holder 5104 are connected by the snap-fit ​​structure 530. The entire filter assembly 500 is installed on the fan light 100. At this point, the main body of the fan light 100 is assembled. Finally, the bracket assembly 600 is fixed to the ceiling with screws. The power cord of the fan light 100 passes through the ceiling box and the hanging rod assembly 700. The assembled unit is hung on the bracket assembly 600. The power cord is connected, and the ceiling box is rotated and fixed on the bracket assembly 600. The fan light 100 is now installed.

[0069] When the fan light 100 is working, the motor starts, and the impeller 320 rotates. External air passes sequentially through the filter assembly 500, the air inlet channel 4101 of the guide ring 410, and the air inlet 2101 of the upper shell 210 into the air chamber 230. The airflow within the air chamber 230 is guided by the guide block 2202 and discharged through the air outlet 2201 via the air outlet channel 2203, achieving air circulation. Users can control the fan and light functions via remote control. The remote control can also be used to set a filter lifespan timer function; different settings accumulate usage time with different weights, and a buzzer indicates replacement when the filter lifespan expires.

[0070] In summary, the fan light 100 of this invention, by setting a guide ring 410, allows external airflow to form a rotating wind field inside the guide ring 410 before entering the upper shell 210, increasing dynamic pressure and significantly improving airflow and energy efficiency. Furthermore, by setting a filter assembly 500 on the outside of the guide ring 410, external airflow can be filtered before entering the guide ring 410, achieving air purification. This design is also convenient to install, aesthetically pleasing, and practical.

Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model.
