[0019] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0020] The following is for reference. Figures 1-7 The range hood 100 according to an embodiment of the present utility model is described as easy for users to disassemble and replace the lighting lamp 30, and the disassembly and assembly process is simple.

[0021] Combination Figures 1-7 As shown, the range hood 100 according to the first aspect of this utility model includes a housing 10, a mounting base 20, and a lighting lamp 30. The housing 10 mainly serves as a load-bearing structural component of the external outline of the range hood 100, protecting and housing the internal structure, and also providing some sound insulation. The lighting lamp 30 illuminates the stove area, improving the user's visibility in the stove area. The mounting base 20 is used to mount and fix the lighting lamp 30.

[0022] Specifically, the mounting base 20 is mounted on the housing 10, and the lighting lamp 30 is mounted on the mounting base 20. The lighting lamp 30 can rotate circumferentially around the rotation axis of the lighting lamp 30 relative to the mounting base 20, so that the rotating lighting lamp 30 is separated from the mounting base 20.

[0023] Specifically, the mounting base 20 is mounted on the housing 10, which facilitates the connection of the lighting lamp 30 to the housing 10 via the mounting base 20. The lighting lamp 30 can rotate around the rotation axis of the mounting base 20. When the lighting lamp 30 rotates to the designated position, it can switch from the connected state to the disconnected state with the mounting base 20, thereby allowing the lighting lamp 30 to be easily removed from the mounting base 20. Furthermore, the user can also remount the lighting lamp 30 on the mounting base 20 by rotating it relative to the mounting base 20, thus achieving the effect of mounting the lighting lamp 30 on the mounting base 20. In summary, by rotating the light bulb 30 circumferentially relative to the mounting base 20 along its own axis of rotation, the light bulb 30 can be easily installed, removed, and replaced on the range hood 100. Moreover, no special tools are required during the operation; the user only needs to turn the light bulb 30 by hand, and there is no need to disassemble the casing 10. The user can easily install and remove the light bulb 30 by simply rotating it outside the casing 10, thereby effectively reducing the difficulty and workload of installation and removal, and improving the convenience for users to replace the light bulb 30 on the range hood 100.

[0024] Therefore, by setting up the range hood 100, it is easy for users to disassemble and replace the lighting lamp 30, and the disassembly and assembly process is simple, thereby improving practicality and convenience.

[0025] According to some optional embodiments of the present invention, combined with Figures 3-6 As shown, the lighting lamp 30 is provided with one of the locking groove 31 and the locking part 21, and the lighting lamp 30 is provided with the other of the locking groove 31 and the locking part 21. An unlocking area 311 is formed on one side of the locking groove 31. The lighting lamp 30 is installed on the mounting base 20 through the locking engagement of the locking groove 31 and the locking part 21. The locking part 21 can be selectively rotated relative to the locking groove 31 to the unlocking area 311.

[0026] When the lighting lamp 30 is provided with a locking groove 31, the lighting lamp 30 is provided with a locking part 21; and when the lighting lamp 30 is provided with a locking part 21, the lighting lamp 30 is provided with a locking groove 31.

[0027] Optionally, combined Figure 4 and Figure 5 As shown, the lighting lamp 30 is provided with a locking groove 31, and the mounting base 20 is provided with a locking part 21. The lighting lamp 30 can achieve a fixed connection with the mounting base 20 through the locking engagement between the locking groove 31 and the locking part 21. When the lighting lamp 30 is rotated to the unlocking area 311 under the action of the user's external force, the locking groove 31 on the lighting lamp 30 contacts the locking part 21 and locks, at which time the lighting lamp 30 separates from the mounting base 20, thereby realizing the fixing and separation of the lighting lamp 30 and the mounting base 20.

[0028] Specifically, in combination Figures 3-6 As shown, the locking groove 31 is constructed as an arc-shaped groove arranged around the rotation axis of the lighting lamp 30, and the locking part 21 is constructed as an arc-shaped piece arranged around the rotation axis of the lighting lamp 30.

[0029] Understandably, since the lighting lamp 30 needs to rotate relative to the mounting base 20 to achieve mutual fixation and separation, the locking groove 31 is constructed as an arc-shaped groove surrounding the rotation axis of the lighting lamp 30, and the locking part 21 is constructed as an arc-shaped piece surrounding the rotation axis of the lighting lamp 30. This allows both the arc-shaped groove and the arc-shaped piece to adapt to the rotation trajectory of the lighting lamp 30. This ensures that the locking groove 31 and the locking part 21 can effectively achieve a locking engagement, and also facilitates their relative rotation in and out, improving the assembly and disassembly of the lighting lamp 30. In addition, the two arc-shaped contours have a self-guiding effect when moving relative to each other. When the arc-shaped piece enters or exits the arc-shaped groove, the arc-shaped trajectory can minimize jamming, thereby improving the smoothness of the operation during the assembly and disassembly of the lighting lamp 30.

[0030] Furthermore, combined Figures 4-6 As shown, there are multiple locking grooves 31, which are spaced apart around the rotation axis of the lighting lamp 30, and an unlocking area 311 is formed between adjacent locking grooves 31; there are multiple locking parts 21, which correspond one-to-one with the multiple locking grooves 31, and the circumferential length of the locking part 21 is less than the circumferential length of the unlocking area 311.

[0031] The above arrangement increases the number of locking grooves 31 and locking parts 21, thereby increasing the locking contact positions between the locking grooves 31 and locking parts 21, improving the force transmission path and force contact area when the lighting lamp 30 is installed on the mounting base 20, and thus improving the installation stability and force uniformity of the lighting lamp 30. Multiple locking grooves 31 are spaced apart around the rotation axis of the lighting lamp 30, which avoids multiple locking grooves 31 forming a continuous closed profile along the circumference of the rotation axis of the lighting lamp 30. Furthermore, an unlocking area 311 is formed between adjacent locking grooves 31. This ensures that the locking part 21 can detach from the mounting base 20 from the unlocking area 311 after rotating out of the locking groove 31, and also facilitates the locking part 21 to pass through the unlocking area 311 before smoothly screwing into the locking groove 31. This allows the locking grooves 31 and locking parts 21 to be fixed or separated by relative rotation alone.

[0032] In addition, the circumferential length of the locking part 21 is less than the circumferential length of the unlocking area 311, so that the locking part 21 can pass smoothly through the unlocking area 311, avoiding the risk of structural interference between the unlocking area 311 and the locking part 21, thereby ensuring the smooth installation and removal between the lighting lamp 30 and the mounting base 20.

[0033] Alternatively, combined Figures 4-6 As shown, a limiting rib 211 protrudes from one side surface of the locking part 21, and the limiting rib 211 abuts against the groove wall 312 of the locking groove 31.

[0034] Understandably, the limiting rib 211 on the locking part 21 rigidly abuts against the groove wall 312 of the locking groove 31. This restricts the movement and displacement of the locking part 21 within the locking groove 31, ensuring the positional stability of the lighting lamp 30 after it is assembled on the mounting base 20, and preventing the lighting lamp 30 from shaking and falling off the mounting base 20. The limiting rib 211 and the groove wall 312 of the locking groove 31 can form an additional support point between the locking part 21 and the locking groove 31, dispersing the vertical load borne by the locking part 21, reducing the risk of deformation of the locking part 21 due to excessive force at a single point, and further improving the stability of the locking state by increasing the contact friction between the locking part 21 and the locking groove 31.

[0035] In addition, the limiting rib 211 can also play a guiding and calibration role. During the process of the locking part 21 entering the locking groove 31, the limiting rib 211 can slide along the groove wall 312 of the locking groove 31 and correct the offset trajectory of the locking part 21, ensuring accurate positioning of the locking action, reducing jamming problems caused by operational deviation or component wear, and taking into account both locking reliability and smoothness of long-term use.

[0036] Alternatively, combine Figure 4 and Figure 5As shown, along the vertical direction, the groove wall 312 of the locking groove 31 protrudes towards the side near the locking part 21. The groove wall 312 includes a side groove wall 3121 and a top groove wall 312. The side groove wall 3121 extends along the vertical direction, and the top groove wall 312 is connected to the side groove wall 3121 and extends radially along the lighting lamp 30. The top groove wall 312 and the unlocking area 311 are spaced apart in the vertical direction. The thickness of the locking part 21 is not greater than the width of the gap.

[0037] The thickness of the locking part 21 is not greater than the vertical spacing between the top groove wall 312 and the unlocking area 311. This ensures that the locking part 21 can move smoothly from the unlocking area 311 into the locking groove 31, avoiding the risk of rigid interference between the locking part 21 and the top groove wall 312 due to excessive thickness, thus ensuring the smooth movement of the locking part 21 when entering or leaving the locking groove 31.

[0038] Preferably, the thickness of the locking part 21 is adapted to the width of the gap, so that the locking part 21 can be stably locked into the limiting space of the locking groove 31. This prevents the locking groove 31 from deforming due to excessive thickness, and also prevents the locking from loosening and causing the risk of accidental unlocking due to excessive thinness. At the same time, reasonable size matching can also reduce the frictional wear between the locking part 21 and the groove wall 312 during long-term use, reduce abnormal wear caused by size mismatch of components, and extend the service life of the overall structure.

[0039] According to some optional embodiments of the present invention, combined with Figures 4-6 As shown, the mounting base 20 is provided with one of the circumferential limiting post 32 and the circumferential limiting hole 22, and the lighting lamp 30 is provided with the other of the circumferential limiting post 32 and the circumferential limiting hole 22. The circumferential limiting post 32 and the circumferential limiting hole 22 are engaged in a limiting fit when the lighting lamp 30 is installed on the mounting base 20.

[0040] When the mounting base 20 is provided with a circumferential limiting post 32, the lighting lamp 30 is provided with a circumferential limiting hole 22; when the mounting base 20 is provided with a circumferential limiting hole 22, the lighting lamp 30 is provided with a circumferential limiting post 32.

[0041] For example, the mounting base 20 is provided with a circumferential limiting hole 22, and the lighting lamp 30 is provided with a circumferential limiting post 32. When the lighting lamp 30 rotates relative to the mounting base 20, the circumferential limiting post 32 on the lighting lamp 30 and the circumferential limiting hole 22 on the mounting base 20 engage in a limiting fit in the circumferential direction of the mounting base 20. At this time, the circumferential limiting post 32 and the circumferential limiting hole 22 will make a sound indicating that the lighting lamp 30 has rotated to the preset locking position, thereby improving the installation accuracy of the lighting lamp 30. Moreover, the limiting fit between the circumferential limiting post 32 on the lighting lamp 30 and the circumferential limiting hole 22 on the mounting base 20 can further limit the circumferential position of the lighting lamp 30, avoiding the risk of the lighting lamp 30 moving around in the circumferential direction of the mounting base 20 during daily use, thereby ensuring the positional stability of the lighting lamp 30.

[0042] Specifically, in combination Figures 4-6 As shown, the lighting lamp 30 is equipped with a flexible arm 33, which is located on the side of the lighting lamp 30 closest to the mounting base 20. The free end of the flexible arm 33 is provided with either a circumferential limiting post 32 or a circumferential limiting hole 22. Specifically, when the mounting base 20 is provided with a circumferential limiting post 32, the free end of the flexible arm 33 is provided with a circumferential limiting hole 22; when the mounting base 20 is provided with a circumferential limiting hole 22, the free end of the flexible arm 33 is provided with a circumferential limiting post 32.

[0043] It is understandable that one end of the elastic arm 33 is connected to the lighting lamp 30 as a fixed support point, while the other end of the elastic arm 33 is a free end that is prone to elastic deformation. For example, the free end of the elastic arm 33 is provided with a circumferential limiting post 32. When the lighting lamp 30 rotates relative to the mounting base 20 under the external force of the user, the free end of the elastic arm 33 is forcibly compressed under the squeezing force of the mounting base 20 and moves downward with the circumferential limiting post 32 until the circumferential limiting hole 22 on the mounting base 20 is aligned with the circumferential limiting post 32. At this time, the circumferential limiting post 32 is not subjected to the squeezing force from the bottom of the mounting base 20. Therefore, under the action of the elastic restoring force of the elastic arm 33 (that is, releasing the previously compressed elastic force), the circumferential limiting post 32 moves upward and is locked in the circumferential limiting hole 22. At this time, the circumferential limiting post 32 and the circumferential limiting hole 22 successfully achieve the limiting engagement effect.

[0044] According to some optional embodiments of the present invention, combined with Figures 4-6 As shown, the mounting base 20 is provided with one of the rotating shaft 34 and the rotating hole, and the lighting lamp 30 is provided with the other of the rotating shaft 34 and the rotating hole. The rotating shaft 34 is rotatably disposed at the rotating hole, and the rotation axis of the lighting lamp 30 passes through the rotating shaft 34.

[0045] When the mounting base 20 is provided with a rotating hole, the lighting lamp 30 is provided with a rotating shaft 34; when the mounting base 20 is provided with a rotating shaft 34, the lighting lamp 30 is provided with a rotating hole.

[0046] For example, the mounting base 20 is provided with a rotating hole, and the lighting lamp 30 is provided with a rotating shaft 34. This ensures that the rotating shaft 34 always moves along a fixed trajectory when rotating within the rotating hole, thereby providing stable rotation conditions for the lighting lamp 30, improving the rotation accuracy of the lighting lamp 30, and also helping the lighting lamp 30 to position itself accurately against the mounting base 20 to a certain extent. The rotation axis of the lighting lamp 30 is coaxial with the rotating shaft 34, which avoids excessive wear caused by eccentric rotation due to axis misalignment, thereby extending the service life of the rotating hole and the rotating shaft 34.

[0047] According to some optional embodiments of the present invention, combined with Figures 1-3 As shown, the housing 10 includes a top plate 11, which forms a downward-opening light groove 111. The mounting base 20 is disposed in the light groove 111, and the lighting lamp 30 is disposed in the light groove 111.

[0048] Below the top plate 11 is the stove area, which can prevent the oil fumes generated during cooking from spreading upwards. The top plate 11 has a light groove 111 facing the opening. The light groove 111 can provide installation space for the mounting base 20 and the light 30. This avoids the mounting base 20 and the light 30 from being exposed and protruding from the top plate 11. On the one hand, it reduces the risk of damage to the mounting base 20 and the light 30 from external interference. On the other hand, it can hide the mounting base 20 and the light 30 in the light groove 111, improve the visual continuity of the light 30 on the top plate 11, and thus improve the practicality and visual perception quality of the range hood.

[0049] Specifically, in combination Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the range hood 100 also includes an elastic locking mechanism 40, which is disposed between the housing 10 and the mounting base 20. The elastic locking mechanism has a locking position and an unlocking position, which are spaced apart in the vertical direction. In the vertical direction, when the elastic locking mechanism 40 is in the locking position, the lighting lamp 30 is inside the lamp groove 111, and when the elastic locking mechanism 40 is in the unlocking position, the lighting lamp 30 is outside the lamp groove 111.

[0050] The locking position 233 and the unlocking position 234 are spaced apart in the vertical direction, which facilitates the positional change of the lighting lamp 30 in the vertical direction with the elastic locking structure, thereby achieving the extension and retraction of the lighting lamp 30 relative to the lamp slot 111. For example, when the user needs to repair or replace the lighting lamp 30, the elastic locking mechanism 40 can be used to drive the lighting lamp 30 out of the lamp slot 111 relative to the housing 10, which facilitates the user's disassembly and separation of the lighting lamp 30; when the user needs to reinstall the lighting lamp 30 back into the housing 10, the elastic locking mechanism 40 can be used to drive the lighting lamp 30 back into the lamp slot 111 relative to the housing 10, which can then achieve the installation and fixation of the lighting lamp 30. In this embodiment, the user can easily disassemble and assemble the lighting lamp 30 without opening the inside of the housing 10, which effectively reduces the difficulty and workload of the disassembly and assembly process of the lighting lamp 30, and improves the convenience for the user to replace the lighting lamp 30 on the range hood 100.

[0051] Alternatively, combined Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the elastic locking mechanism 40 includes a locking member 41 and an elastic member 42. The lighting lamp 30 is mounted on the mounting base 20. The locking member 41 is disposed in the lamp groove 111. The mounting base 20 is disposed on the locking member 41. The locking member 41 selectively locks into the mounting base 20. The elastic member 42 abuts between the housing 10 and the mounting base 20 to provide an elastic restoring force for the mounting base 20 to extend out of the lamp groove 111.

[0052] The lighting lamp 30 is mounted on the mounting base 20. The mounting base 20 is movable relative to the lamp groove 111 along the extension and retraction direction of the lighting lamp 30. The elastic element 42 can undergo elastic deformation to generate an elastic restoring force. The elastic element 42 abuts between the housing 10 and the mounting base 20. When the locking element 41 is locked with the mounting base 20, the locking force between the locking element 41 and the mounting base 20 overcomes the elastic restoring force of the elastic element 42. At this time, the lighting lamp 30 is in the installation position retracted in the lamp groove 111. When the locking element 41 is released from the mounting base 20, the mounting base 20 extends outward from the lamp groove 111 under the action of the elastic restoring force of the elastic element 42, thereby realizing the extension and retraction effect of the lighting lamp 30 relative to the lamp groove 111, which helps to improve the installation and removal efficiency of the lighting lamp 30.

[0053] In addition, the mounting base 20 forms a closed-loop guide rail 23, and the end of the locking member 41 is slidably disposed on the guide rail 23. A locking position 233 is provided on the guide rail 23 near the lighting lamp 30. When the locking member 41 slides to the locking position 233, the locking member 41 locks into the mounting base 20.

[0054] Understandably, the end of the locking member 41 furthest from the light source 30 is connected to the housing 10, and the other end of the locking member 41 closest to the light source 30 is slidably disposed within the guide rail 23. Since the guide rail 23 is constructed in a closed loop, this allows the other end of the locking member 41 to continuously provide tension to the mounting base 20 while simultaneously enabling the other end of the locking member 41 to complete a cyclical movement along the guide rail 23 without the need for additional guiding or reset mechanisms. For example, the end of the locking member 41 closest to the light source 30 starts from its initial position, slides along the guide rail 23 to achieve locking and unlocking actions, and then automatically returns to its initial state along the closed loop path, avoiding the risk of jamming or reset failure due to path breakage in the open guide rail 23.

[0055] Moreover, the closed-loop guide rail 23 allows for more comprehensive constraint on the end of the locking member 41. No matter where the locking hook slides along the path, the slide can provide stable radial support, reducing wear or displacement caused by uneven force on one side and extending the service life of the component.

[0056] Furthermore, combining Figure 2 , Figure 3 , Figure 6 and Figure 7 As shown, the guide rail 23 includes an unlocking section 231 and a locking section 232. The first end of the unlocking section 231 is connected to the first end of the locking section 232, and the first end of the unlocking section 231 and the first end of the locking section 232 together form a locking position 233 recessed in the direction away from the light source 30. When the end of the locking member 41 slides to the locking position 233, the locking member 41 locks into the mounting base 20. The second end of the unlocking section 231 is positioned away from the light source 30 relative to its first end. The second end of the unlocking section 231 is connected to the second end of the locking section 232, and the second end of the unlocking section 231 and the second end of the locking section 232 together form an unlocking position 234 protruding in the direction away from the light source 30. When the end of the locking member 41 slides to the unlocking position 234, the locking member 41 unlocks from the mounting base 20.

[0057] The left side of the guide rail 23 is the locking section 232, and the right side of the guide rail 23 is the unlocking section 231. In the vertical direction, the lower first end of the unlocking section 231 is connected to the lower first end of the locking section 232, and together they form a locking position 233 that is recessed away from the light lamp 30. Since the light lamp 30 is located below the mounting base 20, when the end of the locking member 41 slides to the locking position 233, the recessed contour at the locking position 233 will circumferentially wrap around the locking member 41, preventing it from accidentally shifting in the horizontal direction (such as the front-back direction or the left-right direction). In addition, the mounting base 20 itself has a certain weight, and the weight of the mounting base 20 will naturally press the end of the locking member 41 against the bottom of the recessed contour, further reducing the probability that the locking member 41 will disengage from the locking position 233 in the non-operating state, thereby improving the positional stability of the light lamp 30 in the installed state.

[0058] In addition, since the lower first end of the unlocking section 231 and the lower first end of the locking section 232 are connected to form a locking position 233 that is recessed in the direction away from the light lamp 30, the unlocking section 231 can form a guide surface in the area near the locking position 233, which can reduce the resistance of the end of the locking member 41 when sliding to the locking position 233, thereby making the locking action smoother.

[0059] Furthermore, when unlocking the mounting base 20, the user only needs to apply an upward force or a force away from the direction of the light lamp 30 to make the end of the locking member 41 bypass the locking position 233, thereby disengaging from the recessed area at the locking position 233, and successfully unlocking the locking member 41 and the mounting base 20, so that the light lamp 30 can smoothly extend out of the lamp slot 111.

[0060] Furthermore, the second end of the unlocking segment 231 is positioned away from the lighting lamp 30 relative to its first end. In the vertical direction, the upper second end of the unlocking segment 231 is connected to the upper second end of the locking segment 232, and the connection point of the two together forms an unlocking position 234 protruding in the direction away from the lighting lamp 30. When the end of the locking member 41 slides to the upper unlocking position 234 on the mounting base 20, the mounting base 20 has already driven the lighting lamp 30 out of the lamp slot 111 under the elastic force of the elastic member 42. At this time, it is convenient to perform disassembly and replacement work on the lighting lamp 30.
