Description

Technical Field

[0001] This application relates to the field of kitchen appliance technology, and in particular to a range hood decorative cover and a range hood. Background Technology

[0002] In related technologies, LED lights in range hoods generally adopt an exposed mounting structure, meaning the LED lights are directly and exposed on the outer casing of the machine. This installation method has two significant drawbacks: First, it lacks aesthetic integrity. Because the LED lights are exposed, users can directly observe their surface structure, and a gap inevitably forms between the LED lights and the mounting plate (or casing), compromising the simplicity and integrated visual effect of the overall appearance. Second, it has poor reliability. Range hoods are exposed to high-temperature cooking environments for extended periods during actual use. The exposed LED light surface is directly affected by high temperatures, making it prone to thermal deformation. This leads to a decrease in LED lighting performance, a shortened lifespan, and in severe cases, even loosening of the mounting structure.

[0003] To address the aforementioned reliability issues, some range hoods now incorporate a display panel on the outside of the LED lights. This panel protects the LEDs, reducing the direct impact of high temperatures and extending their lifespan. However, this added display panel must avoid the LED light's mounting structure, resulting in it protruding from the range hood's surface. Furthermore, it creates new assembly gaps at the junction of the display panel and the range hood's side, failing to achieve the clean and elegant design goals of the overall appliance and thus neglecting both reliability and aesthetics. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, or at least partially solve the above-mentioned technical problems, this application provides a range hood decorative cover and a range hood.

[0005] This application provides a decorative cover for a range hood, comprising: A cover, the lower end of which is open; A lighting assembly and a display panel, both of which are embedded in the lower opening of the cover; The display panel is located below the lighting assembly, and the lower surface of the display panel does not protrude beyond the lower opening of the cover.

[0006] The decorative cover for this range hood incorporates the lighting assembly within the lower opening of the cover, preventing it from being exposed and eliminating the aesthetic drawbacks of exposed light fixtures. The display panel is also embedded in the lower surface of the cover and does not protrude beyond the opening, resolving the issue of protruding display panels in related technologies. Furthermore, the embedded structure reduces the assembly gaps between the display panel, the decorative cover, and the lighting assembly, achieving a unified visual effect and enhancing the overall simplicity and sophistication of the appliance. The display panel not only protects the lighting assembly, extending its lifespan, but also conceals assembly gaps, balancing reliability and aesthetics.

[0007] In some embodiments, the lighting assembly includes a mounting bracket and a lighting lamp disposed on the mounting bracket, wherein the lower surface of the mounting bracket and the inner wall of the cover located below the mounting bracket together form a first mounting groove, and the display panel is embedded in the first mounting groove.

[0008] The lower surface of the mounting bracket and the inner wall of the enclosure form a first mounting groove, and the display panel is embedded in the mounting groove, which is equivalent to providing a dedicated installation space for the display panel. The enclosure structure of the mounting groove can limit the display panel from all sides, effectively preventing the display panel from shifting or loosening during the operation of the range hood (such as vibration) or long-term use, and significantly improving the stability and reliability of the display panel assembly.

[0009] In some embodiments, the thickness of the display panel is less than the depth of the first mounting groove. The dimensional difference between the display panel thickness and the depth of the first mounting groove provides ample adjustment space for the assembly process. Even if there are minor dimensional deviations in the display panel or the mounting groove, the display panel can be smoothly embedded into the mounting groove without additional grinding or correction of the components. This effectively reduces the alignment accuracy requirements during assembly, improves production assembly efficiency, and reduces the product defect rate caused by size mismatch issues.

[0010] In some embodiments, the mounting bracket is provided with a first mounting opening, the lighting lamp is disposed at the first mounting opening, and the lower surface of the lighting lamp does not protrude from the lower surface of the mounting bracket.

[0011] The mounting bracket simultaneously fixes the lighting lamp through the first mounting port and the display panel through the lower surface enclosing the first mounting groove with the inner wall of the decorative cover. The mounting structures of the two components are integrated into the mounting bracket, and both adopt a non-protruding design, which can ensure that the lighting lamp and the display panel do not overlap or interfere with each other in the vertical space, making the internal structure of the decorative cover more compact and the layout more orderly, avoiding space waste or functional conflicts caused by protruding components.

[0012] In some embodiments, the middle portion of the mounting bracket is recessed upward to form a second mounting groove, and the first mounting opening is formed on the bottom wall of the second mounting groove.

[0013] The upward-concave structure in the middle of the mounting bracket (similar to a "reinforcing rib" mechanical design) improves its overall rigidity by changing the stress distribution on the mounting bracket. Compared to a flat mounting bracket, the recessed second mounting groove can disperse the vibration stress during the operation of the range hood, reducing bending and deformation of the mounting bracket due to long-term stress, thereby ensuring the installation stability of the lighting and display panel and preventing component misalignment caused by bracket deformation.

[0014] In some embodiments, the lighting lamp includes a housing and a lamp body located within the housing. The housing includes a lampshade and a protective cover protruding from the rear side of the lampshade. The lampshade is located in the second mounting groove, and the protective cover extends through the first mounting opening from the mounting bracket and is snapped and fixed to the mounting bracket.

[0015] The protective cover of the lighting fixture extends through the first mounting opening and is secured by a mounting bracket, forming a dual positioning structure of insertion and snap-fit. The first mounting opening's diameter matches the shape of the protective cover, and the second mounting groove matches the shape of the lampshade, achieving radial limiting and preventing horizontal displacement of the lighting fixture. Furthermore, the snap-fit ​​structure provides axial (vertical) restraint to the lighting fixture, preventing loosening or detachment due to vibrations from the range hood. This fixing method eliminates the need for additional screws or fasteners, simplifying the structure and ensuring long-term installation stability.

[0016] In some embodiments, the height of the lampshade is less than the depth of the second mounting groove. This ensures that the lower surface of the lampshade does not protrude beyond the lower surface of the mounting bracket.

[0017] In some embodiments, the outer side wall of the protective cover is provided with a first snap-fit ​​structure, and the corresponding position of the side wall of the first mounting port is provided with a second snap-fit ​​structure that cooperates with the first snap-fit ​​structure. The first snap-fit ​​structure includes two first snap-fit ​​parts disposed opposite to each other, and the second snap-fit ​​structure includes two second snap-fit ​​parts that snap-fit ​​with the two first snap-fit ​​parts.

[0018] The two opposing snap-fit ​​parts form a clear assembly reference. During assembly, simply align the two first snap-fit ​​parts of the protective cover with the two second snap-fit ​​parts of the first mounting port, and the snap-fit ​​can be completed by simple pressing or rotation. No complicated alignment adjustment is required, which greatly reduces the assembly difficulty and improves production efficiency. During later maintenance, the symmetrical snap-fit ​​structure also makes it easy to release the snap-fit ​​by applying force evenly from both sides, and quickly disassemble the lighting lamp, reducing maintenance time and costs.

[0019] In some embodiments, the first snap-fit ​​portion includes a first elastic piece, the upper end of the first elastic piece being fixedly connected to the outer side wall of the protective cover, and the lower end of the first elastic piece forming an abutment portion, wherein there is a gap between the abutment portion and the outer side wall of the protective cover. The side wall of the first mounting port is provided with a notch, and the first snap-fit ​​part includes a second elastic piece. One end of the second elastic piece is disposed in the notch and connected to the mounting bracket, and the other end extends upward. The inner wall of the second elastic sheet abuts against the abutting part.

[0020] When the first and second elastic plates engage, the elastic force causes the contact portion to fit tightly against the second elastic plate, creating a continuous clamping force. This elastic constraint can adapt to vibrations during the operation of the range hood (such as motor operation and airflow disturbances), absorbing vibration energy through elastic deformation, preventing the rigid connection from loosening or falling off due to vibration, and ensuring the long-term stable fixation of the lighting fixture.

[0021] A second aspect of this application provides a range hood including the range hood decorative cover of any of the above.

[0022] The decorative cover, with its flush-recessed lighting and display components and compact, unified structure, makes the range hood's appearance more concise and neat. This avoids the visual jarring effect of traditional range hood decorative covers with protruding parts and cluttered gaps, aligning with the aesthetic needs of modern kitchens. Furthermore, its comprehensive advantages in reliability, practicality, and user experience give the range hood a differentiated competitive edge over similar products, better meeting consumers' demands for high-quality kitchen appliances.

[0027] To better understand the above-mentioned objectives, features, and advantages of this application, the solution of this application will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of this application, but this application may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some embodiments of this application, and not all embodiments.

[0029] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0030] like Figures 1 to 10 As shown in the figure, this application provides a decorative cover 1 for a range hood, which is used to be assembled on the front or upper side of the main body of the range hood, serving to conceal the internal structure, integrate functional components, and enhance the appearance. Its specific structure is as follows: like Figure 2 As shown, the range hood decorative cover 1 includes a cover body 10, which is made of 1.2mm thick 304 stainless steel sheet or plastic sheet by stamping. It has an overall rectangular cover structure with an open rectangular opening at the bottom, which is fixedly connected to the outer shell 2 of the range hood body. The inner wall of the cover body 10 has a ring of inwardly extending support steps 1011 near the lower opening to support subsequent functional components.

[0031] The range hood decorative cover 1 also includes a lighting assembly. The lighting assembly 11 is embedded in the area above the lower opening of the cover body 10. The light-emitting surface of the lighting assembly 11 faces downward and is fixed on the support step 1011 on the inner wall of the cover body 10.

[0032] The range hood decorative cover 1 also includes a display panel 12, which is embedded in the lower part of the opening at the lower end of the cover body 10, located directly below the lighting assembly 11. The display panel 12 is made of tempered glass, and its surface integrates touch buttons (for adjusting the range hood's fan speed and turning it on / off) and an OLED display screen (for displaying the current fan speed level, cumulative working time, etc.); the central area of ​​the display panel 12 forms a light-transmitting area 121, so that the light emitted by the lighting assembly 11 can be emitted through the light-transmitting area 121.

[0033] The lower surface of the display panel 12 does not protrude beyond the lower opening of the cover 10. That is, the lower surface of the display panel 12 is flush with the end face of the lower opening of the cover 10, or the lower surface of the display panel 12 is above the end face of the lower opening of the cover 10.

[0034] In a specific implementation, the cover 10 includes a front panel 101, a left panel 102, and a right panel 103. The rear part of the lower opening of the cover 10 is used to mate with the outer shell 2 of the range hood, and the front part of the lower opening of the cover 10 is used to install the lighting assembly 11 and the display panel 12. That is, the rear part of the lower end of the left panel 102 and the right panel 103 forms a first mounting part, which is used to assemble and install with the outer shell 2 of the range hood. The front part of the lower end of the left panel 102 and the right panel 103 and the lower end of the front panel 101 form a mounting opening. The lighting assembly 11 and the display panel 12 are both installed corresponding to the mounting opening, and the lower surface of the display panel 12 does not protrude from the mounting opening. When the user's line of sight is level with or higher than the first mounting opening 1114, the installation gap formed between the edge of the display panel 12 and the inner wall of the cover 10 is completely invisible.

[0035] The decorative cover 1 of this application embeds the lighting assembly 11 at the lower opening of the decorative cover 1, avoiding exposure of the lighting assembly 11 and eliminating the defect of exposed lamp body damaging the appearance; the display panel 12 is embedded on the lower surface and does not protrude from the lower opening of the decorative cover 1, solving the problem of the display panel 12 protruding outward in the related technology. At the same time, the embedded structure reduces the assembly gap between the display panel 12 and the decorative cover 1 and the lighting assembly 11, realizing the integrated visual effect of the decorative cover 1, the lighting assembly 112, and the display panel 12, improving the simplicity and grandeur of the overall appearance. The display panel 12 not only protects the lighting assembly 11 and extends the service life of the lighting assembly 11, but also hides the assembly gap, taking into account the requirements of reliability and aesthetics.

[0036] like Figures 3 to 5 As shown, in some embodiments of this application, the lighting assembly 11 includes a mounting bracket 111 and a lighting lamp 112 disposed on the mounting bracket 111. The lower surface of the mounting bracket 111 and the inner wall of the cover 10 located below the mounting bracket 111 together form a first mounting groove 1012, and the display panel 12 is embedded in the first mounting groove 1012.

[0037] Reference Figure 6 and Figure 7 As shown, in a specific implementation, support steps 1011 are respectively provided on the inner walls of the front panel 101, left panel 102, and right panel 103 of the range hood decorative cover 1. The outer contour of the mounting bracket 111 matches the contour of the inner wall of the cover 10. The outer contour of the mounting bracket 111 is rectangular. The outer surface of the mounting bracket 111 along the circumferential direction includes two opposing first surfaces and two opposing second surfaces. One first surface is fitted to the inner wall of the front panel 101, and the two second surfaces are fitted to the left panel 102 and the right panel 103, respectively. One surface (i.e., the upper surface) of the mounting bracket 111 along the axial direction (up and down direction) is fitted to the support step 1011, and the other surface (i.e., the lower surface) forms the bottom wall of the first mounting groove 1012.

[0038] It should be noted that the inner walls of the front side plate 101, left side plate 102, and right side plate 103 located below the mounting bracket 111 form three side walls of the first mounting groove 1012. The rear end of the mounting bracket 111 (the end opposite to the front side plate 101) is bent downwards at 90° to form a bent portion 1113, and the front side of the bent portion 1113 forms the other side wall of the first mounting groove 1012. In other words, the lower surface of the mounting bracket 111 forms the bottom wall of the first mounting groove 1012, and the inner walls of the front side plate 101, right side plate 103, and left side plate 102 located below the mounting bracket 111, along with the front side of the bent portion 1113 of the mounting bracket 111, together form the four side walls of the first mounting groove 1012.

[0039] The lower surface of the mounting bracket 111 and the inner wall of the cover 10 form a first mounting groove 1012, and the display panel 12 is embedded in the first mounting groove 1012. The first mounting groove 1012 provides a dedicated installation space for the display panel 12. The enclosing structure of the first mounting groove 1012 can limit the display panel 12 from all sides, effectively preventing the display panel 12 from shifting or loosening during the operation of the range hood (such as vibration) or long-term use, significantly improving the stability and reliability of the display panel 12 assembly. At the same time, the enclosing structure of the first mounting groove 1012 provides a clear assembly positioning benchmark for the display panel 12. During the assembly process, there is no need to repeatedly adjust the position of the display panel 12, and the embedding and installation can be completed quickly, effectively improving production assembly efficiency and reducing the product defect rate caused by assembly deviation.

[0040] The mounting bracket 111 serves the dual function of mounting the lighting lamp 112 and enclosing the first mounting groove 1012, eliminating the need for a separate mounting bracket 111 or fixing structure for the display panel 12, thus reducing the number of parts. This integrated design not only reduces production and assembly costs but also makes full use of the limited space inside the range hood decorative cover 1, allowing for a more compact and rational layout of the lighting assembly 11 and the display panel 12, avoiding a cluttered internal structure.

[0041] The design of the first mounting slot 1012 can precisely control the installation height of the display panel 12, ensuring that it forms a flat surface with the lower end of the range hood decorative cover 1 and the lower surface of the mounting bracket 111. On the one hand, it improves the overall aesthetics of the range hood decorative cover 1 and avoids the visual abruptness caused by the protruding structure; on the other hand, it reduces cleaning dead corners, making it convenient for users to wipe daily, while avoiding the risk of bumps and knocks that may be caused by the protruding structure.

[0042] Reference Figure 5 As shown, in some embodiments of this application, the thickness of the display panel 12 is less than the depth of the first mounting groove 1012, which is the vertical distance between the mounting opening and the lower surface of the mounting bracket 111. Figure 5 In the figure, M represents the thickness of display panel 12. Figure 5 The difference in thickness N between the display panel 12 and the depth M of the first mounting groove 1012 provides ample adjustment space for the assembly process. Even if there are minor machining dimensional deviations in the display panel 12 or the first mounting groove 1012, the display panel 12 can be smoothly embedded into the first mounting groove 1012 without additional grinding or correction of the parts. This effectively reduces the alignment accuracy requirements during assembly, improves production assembly efficiency, and reduces the product defect rate caused by size matching issues.

[0043] The design that the thickness N of the display panel 12 is less than the depth M of the first mounting groove 1012 ensures that the display panel 12 is completely embedded in the first mounting groove 1012. It can even make the upper surface of the display panel 12 form a concealed fit with the inner wall of the first mounting groove 1012, avoiding appearance defects caused by protrusion or misalignment of the edge of the display panel 12, and making the lower end of the range hood decorative cover 1 flatter and simpler overall.

[0044] In practice, a reserved gap can be formed between the upper surface of the display panel 12 and the upper surface of the mounting bracket 111. This reserved gap can be used to accommodate auxiliary structures such as connecting wires, interface components, or buffer pads of the display panel 12. On the one hand, it avoids the risk of the wires being squeezed or broken, and ensures the stability of the circuit connection of the display panel 12. On the other hand, the addition of components such as buffer pads can further absorb the vibration generated when the range hood is working, reduce the impact of vibration on the display panel 12, and extend its service life.

[0045] Reference Figure 2 and Figure 6 As shown, it should be noted that the display panel 12 can be fixed to the mounting bracket 111 by adhesive or by snap-fit ​​13. Specifically, at least two snap-fit ​​13s are provided on the left and right sides of the upper surface of the display panel 12, and a slot 1115 is provided in the corresponding area of ​​the mounting bracket 111. The display panel 12 is fixed to the mounting bracket 111 by the snap-fit ​​engagement of the snap-fit ​​13s and the slot 1115.

[0046] Reference Figure 6 As shown, in some embodiments of this application, the mounting bracket 111 is provided with a first mounting port 1114, the lighting lamp 112 is provided at the first mounting port 1114, and the lower surface of the lighting lamp 112 does not protrude from the lower surface of the mounting bracket 111.

[0047] The mounting bracket 111 fixes the lighting lamp 112 through the first mounting port 1114, and fixes the display panel 12 through the first mounting groove 1012 enclosing the lower surface of the bracket and the inner wall of the range hood decorative cover 1. The mounting structures of the two components are integrated into the mounting bracket 111, and both adopt a non-protruding design, which can ensure that the lighting lamp 112 and the display panel 12 do not overlap or interfere with each other in the vertical space, making the internal structure of the range hood decorative cover 1 more compact and the layout more orderly, avoiding space waste or functional conflict caused by protruding components.

[0048] Understandably, by hiding the lighting 112 inside the first mounting opening 1114, interference between the lighting 112 and the display panel 12 during installation is avoided, further enhancing the concealment effect of the lighting assembly 11 and the display panel 12 on the range hood decorative cover 1.

[0049] In some embodiments of this application, the middle part of the mounting bracket 111 is recessed upward to form a second mounting groove 1111, and a first mounting opening 1114 is formed on the bottom wall of the second mounting groove 1111.

[0050] The first mounting opening 1114 is located on the bottom wall of the second mounting groove 1111, allowing the lighting lamp 112 to be partially or completely embedded in the second mounting groove 1111, rather than relying solely on the thickness of the mounting bracket 111 for fixation. This structure provides more comprehensive vertical positioning of the lighting lamp 112 (the depth of the second mounting groove 1111 matches the height of the lighting lamp 112), preventing the lighting lamp 112 from loosening or shifting due to vibration, assembly deviations, etc., significantly improving installation stability. Simultaneously, utilizing the recessed space of the mounting bracket 111 itself to accommodate the lighting lamp 112 eliminates the need for additional installation space outside the mounting bracket 111, making the internal structure of the range hood decorative cover 1 more compact, especially suitable for scenarios with limited internal space in the range hood.

[0051] The upward-recessed structure in the middle of the mounting bracket 111 (similar to a reinforcing rib) can improve its overall rigidity by changing the stress distribution of the bracket. Compared to a flat mounting bracket 111, the recessed second mounting groove 1111 can disperse the vibration stress during the operation of the range hood, reduce the bending and deformation of the mounting bracket 111 due to long-term stress, and thus ensure the installation stability of the lighting lamp 112 and the display panel 12 (avoiding component misalignment caused by deformation of the mounting bracket 111).

[0052] In some embodiments of this application, the lighting lamp 112 includes a housing and a lamp body located inside the housing. The housing includes a lampshade 1122 and a protective cover 1121 protruding from the rear side of the lampshade 1122. The lampshade 1122 is located in the second mounting groove 1111. The protective cover 1121 extends through the first mounting opening 1114 and passes through the mounting bracket 111 and is snapped and fixed to the mounting bracket 111.

[0053] In practice, the outer contour of the lampshade 1122 matches the side wall of the second mounting groove 1111. The side wall of the second mounting groove 1111 provides circumferential constraint for the lampshade 1122. The protective cover 1121 extends backward from the first mounting opening 1114 to extend the mounting bracket 111. The first mounting opening 1114 provides circumferential constraint for the protective cover 1121. The mounting bracket 111 is snapped and fixed to the protective cover 1121. The mounting bracket 111 provides axial fastening constraint for the protective cover 1121, preventing it from loosening or falling off due to vibration during the operation of the range hood, thus improving the stability of the assembly structure between the two.

[0054] In use, the lampshade 1122 is located inside the second mounting slot 1111, directly facing the cooking area. Its material (such as transparent / semi-transparent high-temperature resistant material) ensures light penetration while preventing oil fumes and moisture from directly contacting the internal lamp body (such as the LED beads), reducing the impact of oil stains on the lighting effect. The protective cover 1121 protrudes from the rear side of the lampshade 1122 and extends above the mounting bracket 111 (i.e., inside the range hood decorative cover 1), which can cover the circuit parts of the lamp body (such as wiring terminals and drive components), isolating them from the oil fume environment generated by cooking, preventing oil stains from seeping in and causing short circuits or aging of the circuit, and significantly improving the electrical safety and service life of the lighting lamp 112.

[0055] Compared to traditional methods such as screw fixing, the snap-fit ​​fixing method between the protective cover 1121 and the mounting bracket 111 allows for assembly or disassembly without tools: during production, the lighting lamp 112 can be quickly snapped into the mounting bracket 111, improving assembly efficiency; if the lighting lamp 112 needs to be replaced or repaired later, it can be removed simply by unsnap the connection, without disassembling the mounting bracket 111 or other components, greatly reducing maintenance difficulty and cost.

[0056] In some embodiments of this application, the height H of the lampshade 1122 is less than the depth L of the second mounting groove 1111.

[0057] The height H of the lampshade 1122 is less than the depth L of the second mounting groove 1111, ensuring that the lampshade 1122 is completely recessed into the second mounting groove 1111 to form a concave structure. This further ensures that the lower surface of the lighting lamp 112 does not protrude from the lower surface of the mounting bracket 111, thereby ensuring that the lighting lamp 112 will not interfere with the installation of the display panel 12.

[0058] Reference Figure 5 , Figure 6 , Figure 10 and Figure 11 As shown, in some embodiments of this application, the outer side wall of the protective cover 1121 is provided with a first snap-fit ​​structure, and the corresponding position of the side wall of the first mounting port 1114 is provided with a second snap-fit ​​structure that cooperates with the first snap-fit ​​structure. When the lighting lamp 112 is installed on the mounting bracket 111, the first snap-fit ​​structure and the second snap-fit ​​structure cooperate with each other to achieve snap-fit ​​fixation.

[0059] In a specific implementation, the first snap-fit ​​structure includes two first snap-fit ​​parts arranged opposite to each other, and the second snap-fit ​​structure includes two second snap-fit ​​parts that snap-fit ​​with the two first snap-fit ​​parts.

[0060] The mounting bracket 111 is integrally injection molded from modified engineering plastic, with a central indentation forming a second mounting groove 1111. A circular or rectangular first mounting opening 1114 is formed in the center of the bottom wall of the second mounting groove 1111. When the first mounting opening 1114 is circular, a rectangular notch is formed at two opposite positions along the diameter of the sidewall of the first mounting opening 1114 for arranging the second snap-fit ​​portion. When the first mounting opening 1114 is rectangular, a rectangular notch is formed at each of the two opposite sidewalls of the first mounting opening 1114 for arranging the second snap-fit ​​portion. The shape of the first mounting opening 1114 matches the shape of the protective cover 1121, and is not specifically limited here.

[0061] In practice, the number of first snap-fit ​​structures can be set to multiple sets, and the number of second snap-fit ​​structures is equal to and corresponds one-to-one with the number of first snap-fit ​​structures. Multiple sets of first snap-fit ​​structures and multiple sets of second snap-fit ​​structures form a symmetrically distributed clamping and fixing structure. This design can apply balanced constraint forces from both sides of the protective cover 1121, avoiding force shifts (such as tilting or loosening) caused by unilateral snap-fit, ensuring that the lighting lamp 112 maintains a precise position during range hood operation vibrations, long-term use, or transportation, effectively preventing lighting angle shifts, abnormal noises, or component collisions caused by unstable fixing.

[0062] It should be noted that the number of the first snap-fit ​​structure can be reasonably set according to the size and shape of the lighting lamp 112. It can be one, two, three or even more, and no specific limit is made here.

[0063] In some embodiments of this application, the first snap-fit ​​portion includes a first elastic piece 1123, the upper end of which is fixedly connected to the outer side wall of the protective cover 1121, and the lower end of which forms an abutment portion, forming a gap between the abutment portion and the outer side wall of the protective cover 1121; the side wall of the first mounting opening 1114 is provided with a rectangular notch, and the second snap-fit ​​portion includes a second elastic piece 1112, one end of which is located in the notch and connected to the mounting bracket 111, and the other end extends upward; the inner side wall of the second elastic piece 1112 abuts against the abutment portion.

[0064] Both the first elastic sheet 1123 and the second elastic sheet 1112 are elastic structures, meaning they can deform to a certain extent when subjected to external force. They form an elastic clamping constraint by abutting the inner wall of the second elastic sheet 1112 against the abutting portion. A gap is reserved between the abutting portion of the first elastic sheet 1123 and the protective cover 1121 to provide space for its own deformation, allowing it to bend towards the protective cover 1121 during assembly. The second elastic sheet 1112 extends upwards and is fixed at one end within a notch, possessing elastic allowance for deformation outwards (away from the center of the installation). When the two are engaged, the elastic force causes the abutting portion to tightly abut against the second elastic sheet 1112, forming a continuous clamping force. This elastic constraint can adapt to vibrations during the operation of the range hood (such as motor operation and airflow disturbances), absorbing vibration energy through elastic deformation, preventing the rigid connection from loosening or falling off due to vibration, and ensuring the long-term stable fixation of the lighting lamp 112.

[0065] In a specific implementation, the upper end of the first elastic piece 1123 is fixedly connected to the outer wall of the protective cover 1121, and the first elastic piece 1123 first tilts away from the protective cover 1121 from top to bottom to form a first connecting segment 11231, and then tilts towards the protective cover 1121 to form a second connecting segment 11232. The connection between the first connecting segment 11231 and the second connecting segment 11232 forms an abutment part.

[0066] It should be noted that in some embodiments of this application, the upper ends of the two oppositely arranged first elastic pieces 1123 are connected by a connector. The connector is integrally formed with the two first elastic pieces 1123. The connector is correspondingly arranged with the top plate of the protective cover 1121 and is fixed to the protective cover 1121 by screws.

[0067] The protective cover 1121 of the lighting lamp 112 is inserted from the lower side of the second mounting groove 1111 into the first mounting opening 1114. During insertion, the distance between the two opposing first elastic pieces 1123 at the first connecting section 11231 gradually increases from top to bottom, thereby forming a guide structure at the first connecting section 11231 to guide the protective cover 1121 out of the first mounting opening 1114. This can be understood as follows: the distance between the uppermost ends of the two opposing first elastic pieces 1123 in the first connecting section 11231 is less than the distance between the two second elastic pieces 1112, and the distance between the lowermost ends of the two opposing first elastic pieces 1123 in the first connecting section 11231 is less than the distance between the two second elastic pieces 1112. Thus, when the first connecting section 11231 passes through the first mounting opening 1114, there is a gap between the first elastic piece 1123 and the second elastic piece 1112. As the lighting lamp 112 moves upward, the first elastic piece 1123 begins to contact the second elastic piece 1112, and finally presses against the second elastic piece 1112. When the lampshade 1122 is completely attached to the bottom wall of the second mounting groove 1111, the abutting part of the first elastic piece 1123 moves to a position opposite to the second elastic piece 1112. The first elastic piece 1123 resets under its own elasticity, and the abutting part abuts tightly against the second elastic piece 1112. At this time, the two first elastic plates 1123 and the corresponding second elastic plates 1112 form a symmetrical clamping force, which fastens the protective cover 1121 to the first mounting port 1114 from both sides.

[0068] The second connecting segment 11232 increases the contact area between the first elastic sheet 1123 and the second elastic sheet 1112, and at the same time enhances the structural strength of the first elastic sheet 1123.

[0069] During disassembly, simply use a tool to gently press the second elastic piece 1112 from the outside (to deform it outwards towards the notch) to release the latch and easily remove the light bulb 112.
