[0021] This utility model proposes a smoke hood.

[0022] In the embodiments of this utility model, such as Figures 1 to 3 As shown, the range hood includes a main body 10 and a decorative component 30; the main body 10 has a top plate 11; the decorative component 30 is installed on the upper surface of the top plate 11 to cover the gap between the top plate 11 and the bottom plate of the cabinet 40, and the height of the decorative component 30 is adjustable to accommodate gaps of different widths.

[0023] In this embodiment, the decorative piece 30 is fixed to the top plane of the range hood body 10, specifically using screws, clips, or magnetic attachment to ensure a stable connection between the decorative piece 30 and the top plate 11, preventing it from falling off due to range hood vibration. Covering the gap between the range hood top plate 11 and the cabinet bottom plate 40 refers to using the physical structure of the decorative piece 30 to cover the suspended area between them. This can be achieved using a U-shaped, L-shaped, or flat structure, blocking the view and preventing fumes from entering the gap through horizontal extension or vertical obstruction. The vertical dimension of the decorative piece 30 can be adjusted according to actual installation needs, specifically using clamping springs 33, sliding rail structures, or retractable components. By changing the relative position of the upper and lower parts or the overall height of the decorative piece 30, it can adapt to different gap widths between the cabinet 40 and the range hood body 10.

[0024] The adjustable-height decorative piece 30 adapts to the gap width between the top plate 11 of the range hood and the bottom plate of the cabinet 40, using physical blocking to eliminate visual discontinuity and prevent oil fumes from entering the gap. At the same time, the height adjustment function is compatible with different installation scenarios, solving the problems of poor aesthetics and difficult cleaning caused by the fixed-size decorative piece 30 being unable to match the changes in the gap in the existing technology.

[0025] The range hood body 10 serves as the basic structure, with its top plate 11 providing the mounting base for the decorative component 30. The decorative component 30 is installed on the upper surface of the top plate 11 to conceal the gap between the top plate 11 and the bottom plate of the cabinet 40. The height of the decorative component 30 is adjustable to accommodate gaps of varying widths. Through physical concealment, the decorative component 30 eliminates the visual discontinuity between the range hood top plate 11 and the bottom plate of the cabinet 40, while simultaneously preventing oil fumes and dust from entering the gap. The height adjustment function of the decorative component 30 allows it to adapt to changes in gap width in different installation scenarios. For example, for cabinets 40 of different heights, after the air collection box 20 is installed, the gap width between the top plate 11 of the range hood body 10 and the bottom plate of the cabinet 40 will also differ. In this case, adjusting the height of the decorative component 30 will match the actual gap size. The decorative component 30 forms a stable connection with the range hood body 10, ensuring the durability of the concealing effect.

[0026] The above solution resolves the aesthetic issues and difficulties in cleaning caused by the installation gap between the range hood top panel 11 and the cabinet bottom panel 40. The decorative piece 30 effectively conceals the gap between the top panel 11 and the cabinet bottom panel 40, eliminating visual discontinuity and improving the overall aesthetics of the kitchen. Simultaneously, the decorative piece 30 prevents oil fumes and dust from entering the gap, avoiding the problem of difficult-to-clean oil fume accumulation. Because the height of the decorative piece 30 is adjustable, this solution can adapt to varying gap widths in different installation scenarios, enhancing the product's versatility and adaptability. Furthermore, since the decorative piece 30 is integrated into the range hood, no modifications to the cabinet 40 are required, simplifying the installation process and improving user convenience.

[0027] In the smoke hood of this utility model, such as Figures 1 to 3 As shown, the decorative component 30 includes an upper decorative unit 31, a lower decorative unit 32, and a connector 33. The lower decorative unit 32 is connected to the upper surface of the top plate 11, and the upper decorative unit 31 is connected to the lower decorative unit 32 through the connector 33. The upper decorative unit 31 protrudes from the top of the lower decorative unit 32. By adjusting the position of the connector 33 on the lower decorative unit 32, the height of the upper decorative unit 31 protruding from the lower decorative unit 32 can be adjusted.

[0028] The lower decorative unit 32 is fixed to the surface of the top plate 11 as a basic support structure, and its top area has multiple connection positions distributed along the height direction. The connector 33 can be a clamping spring 33, a bolt, or a snap-fit ​​structure, and the vertical displacement of the upper decorative unit 31 can be achieved by selecting different connection positions. The upper decorative unit 31 and the lower decorative unit 32 adopt a nested fit, and its bottom area extends into the interior of the lower decorative unit 32 to form an overlapping section to enhance structural rigidity. When the connector 33 is in the fixed position, the relative movement of the upper decorative unit 31 and the lower decorative unit 32 is restricted by friction or mechanical locking force.

[0029] The decorative unit is fixedly installed on the upper surface of the top plate 11, forming a stable support base. The upper decorative unit 31 is detachably connected to the lower decorative unit 32 via a connector 33, and its protrusion height is determined by the installation position of the connector 33 on the base. When the overall height of the decorative unit 30 needs to be adjusted, the connector 33 is unlocked from its current connection position, moved along the height direction of the lower decorative unit 32 to the target position, and then re-fixed. The position of the upper decorative unit 31 moves with the connector 33, and the height of its protrusion from the lower decorative unit 32 changes accordingly. The nested structure creates a multi-directional contact surface between the upper decorative unit 31 and the lower decorative unit 32, and the interaction of the contact surfaces counteracts the shear force generated by external loads. After adjustment, the decorative unit 30 can precisely match the gap width and maintain structural stability through mechanical connection, avoiding displacement caused by vibration or external forces.

[0030] The above technical solution achieves height adjustability for the decorative element 30, allowing it to adapt to gaps of varying widths. Through its split design and the adjustment mechanism of the connector 33, the decorative element 30 remains stable after height adjustment, preventing loosening or inaccurate positioning. The design of the upper decorative unit 31 protruding from the top of the lower decorative unit 32 increases the coverage area of ​​the decorative element 30, while the nested structure of the upper and lower units enhances overall rigidity. This modular structural design not only improves the adaptability of the decorative element 30 but also ensures structural reliability after adjustment, effectively solving the problems of poor gap coverage and overall structural instability.

[0031] In the smoke hood of this utility model, as shown in Figure 2, the connecting piece 33 is a clamping spring 33. The lower end of the clamping spring 33 is connected to the lower decorative unit 32. The upper decorative unit 31 is inserted between the clamping spring 33 and the lower decorative unit 32. The clamping spring 33 clamps the upper decorative unit 31 onto the lower decorative unit 32. The lower decorative unit 32 has multiple connection positions, which are arranged along the height direction of the lower decorative unit 32. The clamping spring 33 is selectively connected to one of the connection positions.

[0032] The lower end of the clamping spring 33 is fixed to the lower decorative unit 32 by adhesive bonding, and a clamping space with variable spacing is formed between the elastic arm of the clamping spring 33 and the lower decorative unit 32. Multiple connection points are distributed on the rear surface of the lower decorative unit 32 in an equidistant or non-equidistant manner. The upper end of the clamping spring 33 can be designed as an arc or bent structure to enhance the clamping force.

[0033] When the height of the upper decorative unit 31 needs to be adjusted, the clamping spring 33 is pulled away from the current connection position by external force and then adhered to the target connection position. The upper decorative unit 31 is pressed together by the clamping spring 33 and the lower decorative unit 32. This achieves tool-free height adjustment, and after adjustment, the clamping force is evenly distributed on the contact surface of the upper decorative unit 31 and the lower decorative unit 32, preventing displacement caused by vibration or external force.

[0034] The above technical solution solves the problem of positioning stability during height adjustment of the decorative unit. The clamping spring 33, acting as an elastic connector 33, has its lower end fixed to the lower decorative unit 32. The upper decorative unit 31 is inserted into the gap between the clamping spring 33 and the lower decorative unit 32 via a plug-in method, utilizing the clamping force of the spring to achieve tool-free, rapid installation and fixation. Multiple connection positions along the height direction of the lower decorative unit 32 provide discrete positioning options for the clamping spring 33. By selectively connecting one position, the protruding height of the upper decorative unit 31 can be precisely controlled, avoiding positioning deviations that may occur during continuous adjustment. The elastic characteristics of the clamping spring 33 ensure both clamping firmness and allow the user to adjust the connection positions using external force, achieving flexibility and ease of operation for height adjustment.

[0035] In the smoke hood of this utility model, such as Figures 4 to 7 As shown, the lower decorative unit 32 is arranged in a U-shape. The lower decorative unit 32 includes a front part 321, a left part 322 and a right part 323. The front part 321 is adapted to the size of the main body 10 of the range hood in the left-right direction. The left part 322 and the right part 323 are adapted to the size of the main body 10 of the range hood in the front-back direction. The shape of the upper decorative unit 31 is adapted to the shape of the lower decorative unit 32.

[0036] The lateral extension length of the front portion 321 is configured to be consistent with the width of the top plate 11 of the range hood body 10, while the left portion 322 and the right portion 323 extend along the front-rear direction of the range hood body 10, respectively. The U-shaped outline of the upper decorative unit 31 and the lower decorative unit 32 form a nested fit, and the two are connected by a clamping spring 33, which can be selected at different connection positions along the height direction of the lower decorative unit 32.

[0037] During installation, the front portion 321 of the lower decorative unit 32 extends along the left-right direction of the top plate 11 of the range hood body 10, while the left portion 322 and right portion 323 extend along the front-back direction of the top plate 11 to the front and back edges of the bottom plate of the cabinet 40, forming a lateral obstruction. By adjusting the connection position of the clamping spring 33 on the lower decorative unit 32, the upper decorative unit 31 can move up and down relative to the lower decorative unit 32 to accommodate gaps of different heights. Because the U-shaped structure of the lower decorative unit 32 forms a three-dimensional fit with the range hood body 10, the upper decorative unit 31 always maintains a shape match with the lower decorative unit 32 during adjustment, preventing loosening due to misalignment. The front-back extension design of the left portion 322 and right portion 323 provides the lower decorative unit 32 with a larger contact area, thereby improving the overall structural stability. This U-shaped fitting structure ensures that the dimensions of the decorative part 30 in all directions precisely match the range hood body 10 when adjusting its height, ensuring the integrity of the gap obstruction and the reliability of the adjustment operation.

[0038] The above technical solutions improve the dimensional compatibility between the lower decorative unit 32 and the range hood body 10. The U-shaped design allows the lower decorative unit 32 to effectively cover the gap between the range hood body 10 and the cabinet 40, enhancing structural stability. The left-right adaptation of the front part 321 ensures that the lateral coverage area is consistent with the width of the range hood body 10, preventing the front gap from being exposed. The front-back adaptation of the left and right parts 323 allows the lower decorative unit 32 to extend to the front and back edges of the bottom plate of the cabinet 40, enhancing the coverage of the gap. The shape adaptation design of the upper decorative unit 31 and the lower decorative unit 32 ensures that they always maintain a coordinated fit during adjustment, avoiding problems such as loose connection or failure of coverage due to shape differences. This design not only improves the gap coverage effect but also enhances the reliability of the height adjustment function.

[0039] In the smoke hood of this utility model, such as Figures 4 to 7 As shown, the lower decorative unit 32 also includes a first limiting plate 324a and a second limiting plate 325a. The distance between the first limiting plate 324a and the second limiting plate 325a is adapted to the size of the air collection box 20 of the range hood in the left-right direction.

[0040] The first limiting plate 324a and the second limiting plate 325a extend side by side in the front-rear direction and are connected to the front part 321. The distance between the first limiting plate 324a and the second limiting plate 325a is determined by measuring the width of the left and right outer walls of the air collection box 20. The first limiting plate 324a and the second limiting plate 325a can be fixed to the front part 321 with fasteners. When the U-shaped structure formed by the front part 321, the left part 322 and the right part 323 is adapted to the size of the main body 10 of the range hood, the first limiting plate 324a and the second limiting plate 325a can restrain the overall lateral freedom of the lower decorative unit 32 by abutting against the air collection box 20, thereby eliminating the risk of displacement of the decorative part 30.

[0041] The left and right outer walls of the air collection box 20 contact the inner surfaces of the first limiting plate 324a and the second limiting plate 325a, respectively. Since the distance between the first limiting plate 324a and the second limiting plate 325a matches the width of the air collection box 20, and the air collection box 20 is fixed to the top plate 11 of the range hood, the first limiting plate 324a and the second limiting plate 325a are restricted in the left and right directions by the air collection box 20 and cannot undergo lateral displacement. Under this structure, the decorative piece 30 fully achieves its function of concealing the gap between the top plate 11 and the bottom plate of the cabinet 40, and the overall structure can maintain long-term stability without additional reinforcing components.

[0042] The above technical solution effectively solves the positional stability problem caused by the lack of a limiting structure in the left and right directions of the decorative component 30. By adding a first limiting plate 324a and a second limiting plate 325a to abut against the air collection box 20, a lateral constraint is formed on the lower decorative unit 32 by the air collection box 20. This structural design allows the lower decorative unit 32 to precisely match the air collection box 20, avoiding possible lateral displacement during installation. This improves the positional stability of the lower decorative unit 32 while ensuring the complete concealment of the gap between the top plate 11 of the range hood body 10 and the bottom plate of the cabinet 40 by the lower decorative unit 32.

[0043] In the smoke hood of this utility model, such as Figures 4 to 7 As shown, the lower decorative unit 32 also includes a front limiting part 321a, which is located on the rear side of the front part 321. The front limiting part 321a is adapted to the size of the air collection box 20 of the range hood in the left and right direction. The front limiting part 321a is connected to the first limiting plate 324a and the second limiting plate 325a.

[0044] The front limiting part 321a is configured to form a continuous contact surface with the front side plate of the air collection box 20, and its lateral extension length can be adapted to the width range of the air collection box 20. The first limiting plate 324a and the second limiting plate 325a are fixedly connected to both ends of the front limiting part 321a by fasteners to form a frame structure. The contact surface between the front limiting part 321a and the air collection box 20 can be designed as a plane or a composite structure with guide slopes.

[0045] The front limiting part 321a forms a continuous support surface with the rear side of the front part 321, directly abutting against the front sidewall of the air collecting box 20 during installation, thus limiting the forward and backward displacement of the front part 321. The first limiting plate 324a and the second limiting plate 325a form an integral frame with the front limiting part 321a, effectively resisting external forces. A reinforcing rib structure can be provided at the connection between the front limiting part 321a and the first limiting plate 324a and the second limiting plate 325a to improve the overall structure's resistance to deformation.

[0046] Through the above technical solution, this application achieves effective constraint on the lower decorative unit 32 in the front-rear direction, improving installation stability. The connection between the front limiting part 321a and the first limiting plate 324a and the second limiting plate 325a integrates the originally dispersed left and right limiting structures with the front limiting structure into an overall frame, forming a three-dimensional positioning reference. This design not only ensures the dimensional matching between the lower decorative unit 32 and the air collection box 20 in the left-right direction, but also strengthens the overall rigidity of the limiting structure through the lateral extension of the front limiting part 321a.

[0047] In the smoke hood of this utility model, such as Figures 4 to 7 As shown, the lower decorative unit 32 also includes a first reinforcing plate 324b and a second reinforcing plate 325b. The first reinforcing plate 324b connects the left part 322 and the rear end of the first limiting plate 324a, and the second reinforcing plate 325b connects the right part 323 and the rear end of the second limiting plate 325a.

[0048] The first reinforcing plate 324b and the second reinforcing plate 325b extend in the left-right direction. One end of the first reinforcing plate 324b is connected to the rear end of the left portion 322 by fasteners, and the other end is fixed to the rear end of the first limiting plate 324a by welding or integral molding. One end of the second reinforcing plate 325b is connected to the rear end of the right portion 323 by fasteners, and the other end is fixed to the rear end of the second limiting plate 325a by welding or integral molding. The thickness of the first reinforcing plate 324b and the second reinforcing plate 325b can be selected according to actual needs, for example, the same thickness as the left portion 322 and the right portion 323 can be selected. With the setting of the first reinforcing plate 324b and the second reinforcing plate 325b, a stable four-sided frame structure can be formed, effectively enhancing the overall rigidity of the lower decorative unit 32.

[0049] By adding a first reinforcing plate 324b and a second reinforcing plate 325b, the left portion 322 is connected to the rear end of the first limiting plate 324a, and the right portion 323 is connected to the rear end of the second limiting plate 325a, respectively. This strengthens the structural stability between the first limiting plate 324a and the second limiting plate 325a and the left and right portions 322 and 323, respectively. The first reinforcing plate 324b, by connecting the left portion 322 and the rear end of the first limiting plate 324a, can distribute the force between the left portion 322 and the first limiting plate 324a, preventing deformation at the connection point due to external forces or long-term use. The second reinforcing plate 325b, by connecting the right portion 323 and the rear end of the second limiting plate 325a, provides rigid support between the right portion 323 and the second limiting plate 325a, distributing the force between them and preventing deformation at the connection point due to external forces or long-term use. This reinforced design not only improves the overall mechanical strength of the lower decorative unit 32, but also ensures the reliability of the connection between the first limiting plate 324a and the second limiting plate 325a and the left part 322 and the right part 323, thereby maintaining the structural stability of the lower decorative unit 32.

[0050] In another specific embodiment of the lower decorative unit 32 of this utility model, such as... Figures 8 to 9 As shown, the lower decorative unit 32 includes a left decorative part 34, a right decorative part 35, and a connecting plate 36. The left decorative part 34, the right decorative part 35, and the connecting plate 36 together form a U-shape. The left decorative part 34 includes a left front panel 341 and a left decorative panel 344. The right decorative part 35 includes a right front panel 351 and a right decorative panel 354. The connecting plate 36 connects the left front panel 341 and the right front panel 351. The upper decorative unit 31 is adapted to the lower decorative unit 32. The upper decorative unit 31 includes a first decorative part 314, a second decorative part 315, and a connecting piece 316. The first decorative part 314, the second decorative part 315, and the connecting piece 316 together form a U-shape. The first decorative part 314 includes a left front piece 314a and a left decorative piece 314b. The second decorative part 315 includes a right front piece 315a and a right decorative piece 315b. The connecting piece 316 connects the left front piece 314a and the right front piece 315a.

[0051] The left decorative section 34 and the right decorative section 35 are connected by a connecting plate 36 to form a U-shaped frame. The left decorative plate 344 extends backward from the left front plate 341 to cover the left side gap of the main body 10 of the range hood, and the right decorative plate 354 extends backward from the right front plate 351 to cover the right side gap. In the U-shaped structure of the upper decorative unit 31, the left front piece 314a and the right front piece 315a are connected by a connecting piece 316 to form a front mating surface corresponding to the lower decorative unit 32. The left decorative piece 314b and the right decorative piece 315b extend downward and connect with the left decorative plate 344 and the right decorative plate 354 of the lower decorative unit 32, respectively.

[0052] The lower decorative unit 32 achieves dimensional matching with the top plate 11 of the range hood body 10 in both left-right and front-back directions through the combination of the left front panel 341, the right front panel 351 and the connecting plate 36. The left decorative panel 344 and the right decorative panel 354 extend backward from the left and right sides respectively, covering the lateral gap between the top plate 11 and the bottom plate of the cabinet 40, and the extension length can be adjusted according to the gap depth.

[0053] In the smoke hood of this utility model, such as Figures 8 to 9 As shown, the left decorative part 34 also includes a third limiting plate 342, and the right decorative part 35 also includes a fourth limiting plate 352. The front ends of the third limiting plate 342 and the fourth limiting plate 352 are respectively connected to the left and right ends of the connecting plate 36.

[0054] The third limiting plate 342 and the fourth limiting plate 352 can be configured as plate-like structures extending perpendicularly to the connecting plate 36, with their front ends fixedly connected to the connecting plate 36 by welding or riveting. The third limiting plate 342 can be connected to the left front plate 341 of the left decorative part 34 by integral molding or separate assembly, and the fourth limiting plate 352 can be connected to the right front plate 351 of the right decorative part 35 by the same connection method. The distance between the third limiting plate 342 and the fourth limiting plate 352 can be set to be equal to or slightly larger than the left and right width dimensions of the air collection box 20.

[0055] The third limiting plate 342 and the fourth limiting plate 352 extend rearward from the left and right ends of the connecting plate 36, respectively, forming constraint surfaces perpendicular to the connecting plate 36. The left and right sidewalls of the air collecting box 20 contact the inner surfaces of the third limiting plate 342 and the fourth limiting plate 352, respectively, so that the lateral displacement of the two limiting plates can be restricted by the air collecting box 20. The connecting plate 36 is connected to the third limiting plate 342 and the left front plate 341 of the left decorative part 34 through the same connecting node, and the connecting plate 36 is connected to the fourth limiting plate 352 and the right front plate 351 of the right decorative part 35 through the same connecting node.

[0056] Through the above technical solution, the third limiting plate 342 and the fourth limiting plate 352 form a rigid constraint on the lower decorative unit 32 in the left and right directions through the air collection box 20, preventing the lower decorative unit 32 from shifting or tilting when subjected to lateral force, ensuring that the lateral position of the lower decorative unit 32 is fixed, and maintaining the complete shielding function of the decorative part 30 on the gap between the top plate 11 and the cabinet 40.

[0057] In the smoke hood of this utility model, such as Figures 8 to 9 As shown, the left decorative part 34 also includes a third reinforcing plate 343, and the right decorative part 35 also includes a fourth reinforcing plate 353. The third reinforcing plate 343 connects the third limiting plate 342 and the rear end of the left decorative plate 344, and the fourth reinforcing plate 353 connects the fourth limiting plate 352 and the rear end of the right decorative plate 354.

[0058] The third reinforcing plate 343 and the fourth reinforcing plate 353 extend in the left-right direction. One end of the third reinforcing plate 343 is fixed to the rear end of the left decorative panel 344 by welding or integral molding, and the other end is connected to the rear end of the third limiting plate 342 by fasteners. One end of the fourth reinforcing plate 353 is fixed to the rear end of the right decorative panel 354 by welding or integral molding, and the other end is connected to the rear end of the fourth limiting plate 352 by fasteners. The thickness of the third reinforcing plate 343 and the fourth reinforcing plate 353 can be selected according to actual needs, for example, the same thickness as the left decorative panel 344 and the right decorative panel 354 can be selected. The setting of the third reinforcing plate 343 and the fourth reinforcing plate 353 can form a stable four-sided frame structure, effectively enhancing the overall rigidity of the lower decorative unit 32.

[0059] By adding a third reinforcing plate 343 and a fourth reinforcing plate 353, the rear ends of the left decorative panel 344 and the third limiting plate 342, and the rear ends of the right decorative panel 354 and the fourth limiting plate 352, respectively, are connected, thereby strengthening the structural stability between the third and fourth limiting plates 342 and the left and right decorative panels 344 and 354. The third reinforcing plate 343, by connecting the rear ends of the left decorative panel 344 and the third limiting plate 342, can distribute the force between the left decorative panel 344 and the third limiting plate 342, preventing deformation at the connection point due to external forces or long-term use. The fourth reinforcing plate 353, by connecting the rear ends of the right decorative panel 354 and the fourth limiting plate 352, provides rigid support between the right decorative panel 354 and the fourth limiting plate 352, distributing the force between them and preventing deformation at the connection point due to external forces or long-term use. This reinforced design not only improves the overall mechanical strength of the lower decorative unit 32, but also ensures the reliability of the connection between the third limiting plate 342 and the fourth limiting plate 352 and the left decorative plate 344 and the right decorative plate 354, thereby maintaining the structural stability of the lower decorative unit 32.
