Description

Technical Field

[0001] This application relates to the field of range hood technology, and in particular to an easily detachable connecting device and a range hood. Background Technology

[0002] With the development of the range hood industry, the quality of range hoods has continuously improved, and their service life has been greatly extended. During the long service life of a range hood, factors such as changes in overall home decoration style, aesthetic fatigue, or changes in fashion trends may cause users to no longer approve of the style of the range hood they are currently using. However, the range hood's smoke extraction performance can still meet the user's daily needs. Directly replacing the entire range hood would result in a huge waste of resources. Therefore, it is possible to replace parts of the range hood structure, such as the smoke extraction module or the smoke collection hood. However, replacing the smoke extraction module or smoke collection hood is more complicated and requires professionals to use special tools for disassembly and replacement. However, the cost of on-site service is high, which is not conducive to promotion. Summary of the Invention

[0003] To address the aforementioned technical problems of cumbersome and costly disassembly of the fume extraction module or fume collection hood, this application provides a technical solution for an easily detachable connection device and a range hood. Specifically, this application incorporates a drive assembly, a connector, and a locking component. The drive assembly drives the locking component to switch between a locked and unlocked state. When the locking component is in the locked state, it engages with the through hole and the connection hole, thus achieving a fixed connection between the fume extraction module and the main fume extraction module without the need for rivets or screws. This improves the safety and stability of the range hood. Furthermore, users can disassemble the range hood themselves, facilitating disassembly, cleaning, or replacement.

[0012] Furthermore, the rotating component includes a worm, a gear, a stud, and a bushing;

[0013] The worm gear is connected to the power output end of the drive component. The worm gear meshes with the gear, and the gear rotates synchronously with the stud. The bushing is sleeved on the stud and rotatably connected to the stud. One end of the bushing is connected to the push shaft. The drive component drives the worm gear to rotate. The rotation of the worm gear drives the gear to rotate, thereby driving the stud to rotate. The rotation of the stud drives the bushing to move axially along the stud.

[0014] Furthermore, the locking member has a first fixing pin at the end away from the connecting column, and the push shaft has a second fixing pin at the end near the drive link. Both ends of the drive link have fixing holes, and the fixing holes at both ends of the drive link are respectively matched and connected to the first fixing pin and the second fixing pin.

[0015] Furthermore, the folding structure includes a first folding portion, a second folding portion, and a third folding portion. The first folding portion and the third folding portion are disposed on both sides of the connection port, and the second folding portion is disposed between the first folding portion and the third folding portion.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0034] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in sequences other than those illustrated or described herein.

[0035] Please see Figures 1-10 The following is combined with Figures 1-10 A detailed description is provided of an easily detachable connecting device provided in the embodiments of this application.

[0036] This application provides an easily detachable connection device for connecting the fume extraction module 1 and the fume extraction host module 2 in a range hood. Specifically, it includes a drive component 3, a connector 4, and a locking component 5.

[0037] The connecting component 4 includes a flanged structure 41 and a folding structure 42. The flanged structure 41 is disposed on the side wall of the fume extraction host module 2, and the folding structure 42 is disposed at the connection port of the fume extraction module 1. The flanged structure 41 and the folding structure 42 are engaged. The folding structure 42 is provided with a plurality of connection holes 421, and the side wall of the fume extraction host module 2 is provided with through holes 21 that match the connection holes 421. The driving end of the driving component 3 is connected to the locking component 5. The driving component 3 is used to drive the locking component 5 to switch between a locked state and an unlocked state. When the locking component 5 is in the locked state, the locking component 5 is engaged with the through hole 21 and the connection hole 421.

[0038] In the embodiments of this application, such as Figures 1-7 As shown, the flanged structure 41 is set on the bottom side wall of the range hood module 2, and the folding structure 42 is set on the range hood module 1. The flanged structure 41 and the folding structure 42 are engaged to connect the range hood module 1 and the range hood module 2. When the flanged structure 41 and the folding structure 42 are engaged, the locking component 5 can be driven by the drive component 3 to be in a locked state. When the locking component 5 is in the locked state, the locking component 5 cooperates with the through hole 21 and the connecting hole 421 to fix the range hood module 1 and the range hood module 2. The entire fixing process can achieve the fixed connection of the range hood module 1 and the range hood module 2 without the need for rivets or screws, which improves the safety and stability of the range hood. At the same time, users can also disassemble the range hood module 1 to facilitate the disassembly, cleaning or replacement of the range hood, which is highly practical.

[0039] In an optional embodiment, the flanged structure 41 is disposed on the bottom sidewall of the fume extraction host module 2 and extends in a direction perpendicular to the sidewall of the fume extraction host module 2. In a specific embodiment, the flanged structure 41 extends in a direction perpendicular to the bottom sidewall of the front end of the fume extraction host module 2, the bottom sidewall of the left end of the fume extraction host module 2, and the bottom sidewall of the right end of the fume extraction host module 2. In one embodiment, the folding structure 42 can be an L-shaped structure. One end of the folding structure 42 is fixedly connected to the fume extraction module 1 and extends a predetermined distance in a direction parallel to the surface of the fume extraction module 1. The other end of the folding structure 42 extends in a direction perpendicular to the fume extraction module 1. The folding structure 42 is disposed at the connection port on the upper surface of the fume extraction module 1. Specifically, the folding structure 42 is disposed on the left side, the right side, and the front side of the connection port. The specific structures of the flanged structure 41 and the folding structure 42 can be found in [reference needed]. Figure 2 and Figure 3 .

[0040] In practical applications, the connecting hole 421 and the through hole 21 are correspondingly set. Specifically, when the flange structure 41 and the folding structure 42 are engaged, the connecting hole 421 and the through hole 21 are matched. In one embodiment, the number of connecting holes 421 can be 2, 3, 4, 6, 8 or 10, etc. Preferably, the number of connecting holes 421 is 4, of which 2 connecting holes 421 are located on the folding structure 42 on the left side of the connecting port, and the other 2 connecting holes 421 are located on the folding structure 42 on the right side of the connecting port. In another embodiment, the number of through holes 21 can be 2, 3, 4, 6, 8 or 10, etc. Preferably, the number of through holes 21 is 4, of which 2 through holes 21 are located on the bottom left sidewall of the fume extraction host module 2, and the other 2 through holes 21 are located on the bottom right sidewall of the fume extraction host module 2.

[0041] In one optional embodiment, the locking member 5 is provided with a plurality of connecting posts 51. When the locking member 5 is in the locked state, the connecting posts 51 penetrate the through hole 21 and extend into the connecting hole 421. When the locking member 5 is in the unlocked state, the connecting posts 51 are located in the fume extraction host module 2 or one end of the connecting posts 51 is located in the through hole 21.

[0042] In this embodiment, the diameter of the connecting post 51 is smaller than the diameter of the through hole 21, so that when the locking member 5 is in the locked state, the connecting post 51 can penetrate the through hole 21 and extend into the connecting hole 421 to achieve a fixed connection between the connecting hole 421 and the through hole 21. When it is necessary to disassemble the fume extraction module 1, the locking member 5 can be driven into an unlocked state by the driving component 3. When the locking member 5 is in the unlocked state, the connecting post 51 is located inside the fume extraction host module 2 or one end of the connecting post 51 is located inside the through hole 21, so as to release the fume extraction module 1 from the fume extraction host. Locking module 2 allows the fume extraction module 1 to be removed from the fume extraction host module 2. Furthermore, in the fixed connection between the fume extraction module 1 and the fume extraction host module 2, the locking element 5 can be controlled to be in a locked or unlocked state, thus enabling the fixing and disassembly of the fume extraction module 1 and the fume extraction host module 2. This allows users to easily disassemble or fix the fume extraction module 1 in the range hood without tools. The operation is simple, and no rivets or screws are required to achieve a fixed connection between the fume extraction module 1 and the fume extraction host module 2, further improving the safety and stability of the range hood.

[0043] In practical applications, the number of connecting posts 51 is equal to the number of through holes 21 or the number of connecting holes 421, that is, there are 4 connecting posts 51, and each connecting post 51 is matched with its corresponding through hole 21 and connecting hole 421.

[0044] In an optional embodiment, the folding structure 42 includes a first folding portion 422, a second folding portion 423, and a third folding portion 424. The first folding portion 422 and the third folding portion 424 are disposed on both sides of the connection port, and the second folding portion 423 is disposed between the first folding portion 422 and the third folding portion 424. The first folding portion 422 and the third folding portion 424 are provided with the connection hole 421.

[0045] Specifically, such as Figure 2 and Figure 3 As shown, the first folding part 422 matches the flange structure 41 of the bottom left sidewall of the range hood module 2, the second folding part 423 matches the flange structure 41 of the bottom front sidewall of the range hood module 2, and the third folding part 424 matches the flange structure 41 of the bottom right sidewall of the range hood module 2. That is, when the flange structure 41 and the folding structure 42 are engaged, the first folding part 422 overlaps the flange structure 41 of the bottom left sidewall of the range hood module 2, and the second folding part 423 overlaps the bottom front sidewall of the range hood module 2. On the flange structure 41, the third folded part 424 overlaps the flange structure 41 on the bottom right side wall of the fume extraction host module 2. In one embodiment, the first folded part 422, the second folded part 423, and the third folded part 424 are all L-shaped structures. Furthermore, by setting a folding structure 42 including the first folded part 422, the second folded part 423, and the third folded part 424, it can be engaged with the flange structure 41 on the fume extraction host module 2, thereby realizing the connection between the fume extraction host module 2 and the fume extraction module 1 through the flange structure 41 and the folding structure 42.

[0046] In one alternative implementation, such as Figures 5-7 As shown, the above-mentioned connecting device also includes a drive link 6 and a guide rail 7. One end of the drive link 6 is connected to the drive end of the drive assembly 3, and the other end of the drive link 6 is connected to the locking member 5. The guide rail 7 is located on the fan frame 22 of the fume extraction host module 2. The end of the locking member 5 away from the connecting column 51 is connected to the slider on the guide rail 7. The drive link 6 is used to drive the locking member 5 to move axially along the guide rail 7.

[0047] In this embodiment, by connecting one end of the drive link 6 to the drive end of the drive assembly 3 and the other end of the drive link 6 to the locking member 5, the drive assembly 3 drives the drive link 6 to move. The movement of the drive link 6 can drive the locking member 5 to move. At the same time, the end of the locking member 5 away from the connecting column 51 is connected to the slider on the guide rail 7, so that the drive link 6 drives the locking member 5 to move along the axial direction of the guide rail 7, thereby ensuring that the movement direction of the locking member 5 is consistent with the axial direction of the guide rail 7, which can improve the stability of the drive.

[0048] In practical applications, the guide rail 7 is perpendicular to the straight line formed by the multiple through holes 21, so that when the locking member 5 moves along the axial direction of the guide rail 7 to the preset position, the connecting post 51 on the locking member 5 can be matched and connected with the through hole 21.

[0049] In an optional embodiment, the locking member 5 is provided with a first fixing pin at the end away from the connecting column 51, the push shaft 33 is provided with a second fixing pin at the end near the drive link 6, and both ends of the drive link 6 are provided with fixing holes, which are respectively matched and connected to the first fixing pin and the second fixing pin.

[0050] Specifically, the first fixing pin can be a cylindrical pin, which is used to fix the drive link 6 and the locking member 5. The second fixing pin can also be a cylindrical pin, which is used to fix the drive link 6 and the push shaft 33, so as to ensure that the push shaft 33 can drive the locking member 5 to move axially along the guide rail 7 through the drive link 6, thereby driving the locking member 5 to switch between the locked state and the unlocked state.

[0051] In an optional embodiment, the drive assembly 3 includes a drive member 31, a rotating member 32, and a push shaft 33. The power output end of the drive member 31 is connected to the rotating member 32. The rotating member 32 is connected to one end of the push shaft 33, and the other end of the push shaft 33 is connected to the drive linkage 6. The drive member 31 drives the rotating member 32 to rotate. The rotation of the rotating member 32 drives the push shaft 33 to extend and retract along the axial direction of the push shaft 33, thereby driving the drive linkage 6 to move.

[0052] In the embodiments of this application, such as Figures 8-10 As shown, the driving component 31 can drive the rotating component 32 to rotate. The rotation of the rotating component 32 can drive the push shaft 33 to move along the axial direction of the push shaft 33, thereby driving the drive linkage 6 to move, which in turn can drive the locking component 5 to move along the axial direction of the guide rail 7, so as to realize the switching of the locking component 5 between the locked state and the unlocked state. In a specific embodiment, the driving component 31 can be an electric motor, and the push shaft 33 can be a push rod.

[0053] In an optional embodiment, the rotating component 32 includes a worm 321, a gear 322, a stud 323, and a bushing 324. The worm 321 is connected to the power output end of the driving component 31, and the worm 321 meshes with the gear 322. The gear 322 rotates synchronously with the stud 323. The bushing 324 is sleeved on the stud 323 and rotatably connected to it. One end of the bushing 324 is connected to the push shaft 33. The driving component 31 drives the worm 321 to rotate. The rotation of the worm 321 drives the gear 322 to rotate, thereby driving the stud 323 to rotate. The rotation of the stud 323 drives the bushing 324 to move axially along the stud 323.

[0054] In one specific embodiment, such as Figure 10 As shown, the bushing 324 is provided with a limit structure, and the bushing 324 is threaded onto the stud 323. When the stud 323 rotates, the bushing 324 can move along the axial direction of the stud 323 under the rotation of the thread, thereby driving the push shaft 33 to move.

[0055] In practical applications, the rotating component 32 also includes a bearing 325, which is sleeved on the stud 323 to ensure that the rotation center of the stud 323 coincides with the axis of the bearing 325.

[0056] In an optional embodiment, a mesh structure 8 is also included, which is disposed on one end of the fume extraction host module 2 near the fume extraction module 1.

[0057] In this embodiment, by providing a mesh structure 8 on the end of the fume extraction host module 2 near the fume extraction module 1, the fume extraction host module 2 can be protected from the influence of the external environment, such as dust and moisture. This can effectively prevent dust and moisture from entering the fume extraction host module 2, thereby ensuring the normal operation of the fume extraction host module 2 and extending its service life.

[0058] The following describes in detail the fixing and disassembly methods of the fume extraction module 1 and the fume extraction host module 2, taking into account the specific structure of the above-mentioned connecting device.

[0059] When it is necessary to connect the fume extraction module 1 and the fume extraction host module 2, the folding structure 42 and the flange structure 41 are engaged so that the through hole 21 is aligned with the connecting hole 421. Then, the drive assembly 3 can drive the locking member 5 to move axially along the guide rail 7 through the drive linkage 6, so that the connecting post 51 on the locking member 5 passes through the through hole 21 and extends into the connecting hole 421, thereby realizing the fixed connection between the fume extraction module 1 and the fume extraction host module 2.

[0060] When it is necessary to disassemble the fume extraction module 1, the driving component 3 can be used to drive the locking component 5 into an unlocked state. At this time, the connecting post 51 on the locking component 5 is located inside the fume extraction host module 2, or one end of the connecting post 51 on the locking component 5 is located inside the through hole 21, so as to release the lock between the fume extraction module 1 and the fume extraction host module 2, and then the fume extraction module 1 can be removed from the fume extraction host module 2.

[0061] As can be seen from the above technical solutions of the embodiments of this application, the following technical effects are achieved:

[0062] This application sets up a drive component, a connector, and a locking component so that the drive component can drive the locking component to switch between a locked state and an unlocked state. When the locking component is in the locked state, it engages with the through hole and the connection hole, thereby achieving a fixed connection between the fume extraction module and the fume extraction host module without the need for rivets or screws. This improves the safety and stability of the range hood. At the same time, users can also disassemble the range hood themselves, making it easy to disassemble, clean, or replace the range hood.

[0063] This application also provides a range hood, which includes the easily detachable connecting device as described above. Since the range hood has all the technical features of the aforementioned easily detachable connecting device, the range hood in this embodiment should also have the same technical effect, which will not be repeated here.

Specific devices may include more or fewer components than shown, or combinations of certain components, or arrangements of different components. It should be understood that the methods, apparatuses, etc., disclosed in this embodiment can be implemented in other ways.
