[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

These terms are primarily intended to better describe the present invention and its embodiments and are not intended to limit the devices, elements, or components indicated to having a specific orientation, or to being constructed or operated in a specific orientation.

[0026] Furthermore, some of the above terms may be used to express other meanings besides indicating a position or location. For example, the term "on" may also be used to indicate a dependency or connection in certain circumstances. Those skilled in the art will understand the specific meanings of these terms in the present invention based on the specific circumstances.

[0027] Furthermore, the terms "installed," "disposed," "provided with," "connected," and "connected" should be interpreted broadly. For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections or indirect connections through an intermediary; or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in the present invention based on specific circumstances.

[0028] Furthermore, the terms "first," "second," etc., are primarily used to distinguish between different devices, elements, or components (which may or may not be of the same type and configuration), and are not intended to indicate or imply the relative importance or quantity of the devices, elements, or components indicated. Unless otherwise specified, "plurality" means two or more.

[0029] The present invention discloses a modular oil fume removal device, which can conveniently remove the oil fume separator and the smoke removal box of the range hood for replacement and cleaning, and is easy to maintain; and adopts a modular setting, which is convenient for installing and removing the appropriate number of oil fume separators and smoke removal boxes according to the oil fume removal needs.

[0030] Please also refer to Figures 1 to 4 , is a structural schematic diagram of a modular oil fume removal device provided in an embodiment of the present invention, the modular oil fume removal device includes a shell 10 and an oil fume treatment module 20, a cavity 1a with an opening facing downward is formed inside the shell 10, the oil fume treatment module 20 is rotatably and detachably arranged in the cavity 1a, the oil fume treatment module 20 can be rotated from the opening of the cavity 1a into the cavity 1a and fixed, or can be rotated from the opening of the cavity 1a out of the cavity 1a.

[0031] It is understandable that when the oil fume treatment module 20 needs to be cleaned or replaced, the oil fume treatment module 20 can be rotated to rotate out of the cavity 1a from the opening of the cavity 1a. The operation is simple and fast, and maintenance is convenient.

[0032] like Figure 5 and Figure 6 As shown, Figure 5They are respectively a schematic diagram of the structure and a schematic diagram of the internal structure of an existing range hood. In order not to affect the cooks (to prevent the cooks from bumping into the range hood) and to ensure the oil fume extraction effect, the range hood is usually installed above the stove in the kitchen during actual use, that is, the front end of the box B is relatively high from the ground. As is known to all, for the oil fume treatment component, after a period of use, the oil fume separation plate and the smoke removal cotton of the smoke removal box are all stained with grease. If they are not replaced in time, the oil fume extraction effect of the range hood will be greatly affected. Therefore, there is a situation where the oil fume treatment component of the range hood needs to be replaced regularly. When the oil fume treatment component A needs to be taken out for replacement, the operator needs to use items such as a ladder or a table. Furthermore, since range hoods are often installed in the kitchen, with the front and bottom facing the kitchen and the rest of the hood obscured by the kitchen wall, the fume extraction box can usually only be removed from the front and bottom of the range hood. However, since oil fumes typically pass through the fume separation tray C and the fume extraction box from bottom to top, the fume separation tray C of existing range hoods is located at the bottom of the box body B via a partition. This means that the fume extraction box A of existing range hoods must be removed from the front of the box body B. This removal and removal method is very cumbersome and poses a safety hazard. This is because the fume treatment assembly A is inherently heavy, and operators using ladders, tables, or other objects can easily lose their balance and fall, or accidentally drop the fume treatment assembly, posing a significant safety hazard.

[0033] The modular oil removal device of the present application integrates the fume removal box and the oil fume separation plate into an oil fume treatment module 20, allowing the oil fume treatment module to be removed from the downward opening of the housing 1a, unlike the removal position of the fume removal box B in existing range hoods. Compared to existing range hoods, the modular oil removal device of the present application facilitates the removal of the oil fume treatment module 20 from the downward opening of the housing 1a, which is close to the stove and lower to the ground. This allows the operator to stand on the ground and rotate the oil fume treatment module 20 to remove it from the housing 1a without the aid of a ladder or table, resulting in convenient and safe operation.

[0034] In addition, since the oil fume treatment module 20 can be detachably installed in the cavity 1a, different numbers of oil fume treatment modules 20 can be installed and disassembled in the housing 10 according to the use site or the amount of oil fume generated to meet different usage requirements.

[0035] In this embodiment, if Figure 1 and Figure 2 As shown, in order to enable the oil fume treatment module 20 to rotate relative to the cavity 1a to enter or leave the cavity 1a, the oil fume treatment module 20 is provided with a first adapter portion 30, and a second adapter portion 40 is provided on the inner wall surface of the cavity 1a corresponding to the first adapter portion 30, and the first adapter portion 30 is rotatably connected to the second adapter portion 40.

[0036] Specifically, each oil fume treatment module 20 is provided with two first adapters 30, which are located at one end of the oil fume treatment module 20 away from the front end 11 of the housing 10, and are spaced apart therebetween. The two spaced-apart first adapters 30 allow the oil fume treatment module 20 to be rotatably connected to the second adapter 40, enhancing its rotational stability and connection strength, thereby extending the service life of the modular oil removal device. The front end 11 of the housing 10 refers to the end of the modular oil removal device that, when in use, is typically installed in a kitchen, with the housing 10 facing the interior of the kitchen and, when in use, the end of the housing 10 facing the cook.

[0037] Furthermore, the number of the second adapter portion 40 is one or corresponds to the number of the first adapter portions 30. Preferably, the number of the second adapter portion 40 is one, and the second adapter portion 40 is a long cylindrical rod, with both ends respectively abutting against the inner wall surface of the cavity 1a, thereby reducing the weight of the modular oil fume removal device and facilitating transportation, installation, and use.

[0038] In this embodiment, if Figure 4 As shown, the first adapter portion 30 includes a connecting portion 31 fixed to the oil fume treatment module 20 and a bent portion 32 bent upward from one end of the connecting portion 31 away from the oil fume treatment module 20, and the bent portion 32 cooperates with the second adapter portion 40. Specifically, the connecting portion 31 and the bent portion 32 are both sheet-shaped, and the connecting portion 31 and the bent portion 32 can be integrally formed or welded. Preferably, the connecting portion 31 and the bent portion 32 can be integrally formed, so that the rigidity of the first adapter portion 30 is higher, thereby improving the connection strength between the first adapter portion 30 and the second adapter portion 40.

[0039] More specifically, the bent portion 32 is Preferably, the bent portion 32 is The arc-shaped hook is used to cooperate with the second adapter portion 40, making the connection more compact.

[0040] It is understandable that the bent portion 32 is The arc-shaped hook is connected to the second adapter part 40 through its arc, that is, the hook connection method. When the oil fume treatment module 20 needs to be replaced or cleaned, there is no need to rotate the oil fume treatment module 20 away from the cavity 1a. It is only necessary to rotate the oil fume treatment module 20 to the outside of the cavity 1a, so that the parts of the oil fume treatment module 20 that need to be replaced or cleaned (such as the various levels of oil removal units) are facing the outside of the cavity 1a. At this time, the oil fume treatment module 20 can be hung on the second adapter part 40 through the bending part 32. The parts that need to be replaced or cleaned of the oil fume treatment module 20 can be removed for replacement or cleaning, which is more convenient and quick. Only the parts that need to be replaced or cleaned need to be removed, which is more efficient.

[0041] In addition, by means of a hook connection, when disassembling and assembling an appropriate number of oil fume treatment modules 20 according to the oil removal requirements, for example, when disassembling the oil fume treatment module 20, the oil fume treatment module 20 can be rotated outside the cavity 1a, and the bent portion 32 can be lifted upward to disengage it from the second adapter portion 40 to completely detach the oil fume treatment module 20 from the cavity 1a. The steps for installing the oil fume treatment module 20 can refer to the disassembly steps. By means of a hook connection, the entire oil fume treatment module 20 can be disassembled and assembled, which is more efficient and can timely disassemble and assemble an appropriate number of oil fume treatment modules 20 according to the oil removal requirements.

[0042] Furthermore, the first adapter portion 30 further includes a fixing portion 33, which is fixedly mounted on the oil fume treatment module 20, and the connecting portion 31 is fixedly connected to the fixing portion 33. Specifically, the fixing portion 33 is sheet-shaped and attached to the oil fume treatment module 20. The connecting portion 31 is vertically fixed to the fixing portion 33 and can be fixed to the fixing portion 33 by welding. This provides a reliable connection and is not easily broken by external forces when the oil fume treatment module 20 is disassembled and assembled, thereby extending the service life of the modular oil fume removal device.

[0043] In this embodiment, if Figure 2 and Figure 3 As shown, in order to allow the oil fume treatment module 20 to be fixed within the cavity 1a after rotating from the opening of the cavity 1a into the cavity 1a, a first positioning portion 12 is provided on the inner wall surface of the cavity 1a, and a second positioning portion 21 is provided on the oil fume treatment module 20 corresponding to the first positioning portion 12. The second positioning portion 21 cooperates with the first positioning portion 12 to fix the oil fume treatment module 20 within the cavity 1a of the housing 10. Specifically, the first positioning portion 12 is provided on the inner wall surface of the cavity 1a near the front end 11 of the housing 10, and the second positioning portion 21 is provided at the other end of the oil fume treatment module 20 opposite to the end where the first adapter portion 30 is provided.

[0044] More specifically, the first positioning portion 12 includes a first step surface 12a, and the second positioning portion 21 includes a second step surface 21a that cooperates with the first step surface 12a. The first step surface 12a and the second step surface 21a are fitted together to fix the oil fume treatment module 20.

[0045] It can be understood that when the oil fume treatment module 20 rotates from the opening of the cavity 1a into the cavity 1a, the second step surface 21a abuts and fits against the first step surface 12a, and the first step surface 12a and the second adapter portion 40 can respectively support the two ends of the oil fume treatment module 20, thereby fixing the oil fume treatment module 20 in the cavity 1a.

[0046] In this embodiment, if Figure 4 As shown, the oil fume treatment module 20 includes a box body 22 and at least two oil removal units, namely a first-level oil removal unit 23 and a second-level oil removal unit located above the first-level oil removal unit 23. The upper and lower parts of the box body 22 are both provided with openings. The first-level oil removal unit 23 can be detachably arranged at the lower opening of the box body 22, and the second-level oil removal unit can be detachably arranged at the upper opening of the box body 22.

[0047] That is to say, when it is necessary to clean or replace the first-level oil removal unit 23 and / or the second-level oil removal unit, the oil fume treatment module 20 can be rotated away from the opening of the cavity 1a, and the first-level oil removal unit 23 and / or the second-level oil removal unit can be disassembled and assembled for cleaning or replacement. The operation is simple and convenient, reducing the maintenance difficulty of the modular oil removal device.

[0048] In this embodiment, if Figure 1 As shown, the boxes 22 of multiple oil fume treatment modules 20 are arranged side by side, with gaps formed between adjacent boxes 22, between the first box 22 and the housing 10, and between the last box 22 and the housing 10. These gaps are provided with sealing assemblies for sealing the gaps. The sealing assemblies seal the gaps, allowing as much oil fume as possible to enter the oil fume treatment modules 20 for degreasing, thereby improving the oil fume absorption rate of the modular degreasing device.

[0049] Specifically, if Figure 7 As shown, the sealing assembly includes a long strip of sealing strip 41 and a pressing component 42. The sealing strip 41 is arranged on the gap to close the gap. The pressing component 42 is covered on the sealing strip 41 to press the sealing strip 41 in the gap to improve the sealing performance of the sealing strip 41 in closing the gap.

[0050] More specifically, the sealing strip 41 can be a rubber sealing strip 41 or a plastic sealing strip 41. Preferably, the sealing strip 41 is a rubber sealing strip 41, which has good corrosion resistance, strong elasticity, good sealing effect, and is waterproof, which can extend the service life of the modular degreasing device.

[0051] In this embodiment, the pressing component 42 includes a pressing portion 421 and shielding portions 422 disposed on either side of the pressing portion 421. A housing space A is formed between the shielding portions 422 and the pressing portion 421. The sealing strip 41 is located within the housing space A, and the pressing portions 421 compress the sealing strip 41. The sealing strip 41 is located within the housing space A, and the pressing component 42 protects the sealing strip 41 from damage or cuts caused by impact, thereby extending the service life of the modular degreasing device.

[0052] Furthermore, the pressing member 42 includes two extensions 423, which extend from the two shielding portions 422, away from the pressing portion 421, toward the housing space A. The two extensions 423 are perpendicular to the two shielding portions 422. The two extensions 423 increase the cross-sectional area of ​​the pressing member 42, thereby improving the strength of the pressing portion 421 and further extending the service life of the modular degreasing device.

[0053] An embodiment of the present invention provides a modular oil removal device, in which the oil fume treatment module is rotatably and detachably arranged in the cavity of the shell, and can be rotated from the opening of the cavity into the cavity, or rotated from the opening of the cavity out of the cavity, so that the oil fume treatment module is easy to take out for replacement or cleaning, and maintenance is more convenient. In addition, by adopting a detachable arrangement of multiple oil fume purification modules, users can install and remove an appropriate number of oil fume treatment modules according to actual oil removal needs.

[0054] In addition, by setting sealing strips to seal the gaps between the oil fume treatment modules and the gaps between the oil fume treatment modules and the outer shell, as much oil fume as possible can enter the oil fume treatment module for degreasing, thereby improving the oil fume suction rate of the modular degreasing device.

[0055] The above is a detailed introduction to a modular oil fume removal device disclosed in an embodiment of the present invention. Specific examples are used herein to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand a modular oil fume removal device of the present invention and its core idea. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
