Description

Technical Field

[0001] The invention relates to the technical field of electrical appliances, and in particular to a disassembly and assembly structure and a range hood. Background Art

[0002] At present, the air inlet cover is the first barrier of the range hood air inlet, which not only protects users from being harmed by the rotating wind wheel, but also performs preliminary filtering of the oil smoke entering the air inlet. The air inlet cover is easy to adhere to oil smoke stains, so it needs to be removed and cleaned frequently in daily use, which puts forward the requirement for the convenient disassembly and assembly of the air inlet cover.

[0003] In the prior art, a magnet is provided on the air inlet hood, and the air inlet hood and the guide plate are fixedly connected by magnetic attraction, so that the air inlet hood can be disassembled and assembled without tools, which solves the problem of convenient assembly and disassembly of the air inlet hood to a certain extent. However, when the magnetism of the magnet is weak, the magnetic attraction of the air inlet hood on the guide plate is weak, and the adsorption is unreliable. In order to ensure the adsorption reliability of the air inlet hood, a strong magnet with strong magnetism is usually used. When disassembling and assembling the air inlet hood, the magnetic attraction of the air inlet hood is large, which makes the strength and feel of disassembly and assembly poor; when disassembling the air inlet hood, a large force is required to pull the air inlet hood out, which is easy to pull the range hood off; the magnetism of the permanent magnet will not change under normal circumstances, and the magnetic attraction of the air inlet hood is difficult to adjust. Summary of the invention

[0004] The main purpose of the present invention is to provide a disassembly and assembly structure and a range hood to solve the problem in the prior art that the air inlet cover is subjected to a large magnetic attraction force when disassembling and assembling the air inlet cover, resulting in poor strength and feel during disassembly and assembly.

[0005] To achieve the above-mentioned objectives, the present invention provides a disassembly and assembly structure, comprising two components, both of which are provided with magnetic parts, one of the two components having an installation cavity, at least a portion of the other of the two components being located in the installation cavity and forming a mating portion, the two components being respectively a fixed component and a detachable component, and the detachable component being pressed against the fixed component by the repulsive force between the two magnetic parts to fix the detachable component.

[0006] Furthermore, when the detachable component is in a fixed state, the two magnetic components are staggered and the same poles of the two magnetic components are arranged opposite to each other.

[0007] Furthermore, the two magnetic parts are staggered along the installation direction of the detachable component.

[0008] Furthermore, a magnetic member is provided on a portion of the matching portion that matches with the peripheral wall of the installation cavity.

[0009] Furthermore, a magnetic member is provided on the peripheral wall of the installation cavity.

[0010] Further, when the detachable component is in a fixed state, there is a gap between the two magnetic parts in a direction perpendicular to the installation direction of the detachable component.

[0011] Furthermore, the gap is in the range of 0.5 to 1.5 mm.

[0012] Furthermore, each component is provided with a mounting through hole, and each magnetic member is fixed to the inner side of the corresponding component and has a protrusion extending into the corresponding mounting through hole.

[0013] Further, the thickness of one protrusion extending into the corresponding mounting through hole is greater than or equal to the depth of the corresponding mounting through hole, and / or the thickness of another protrusion extending into the corresponding mounting through hole is less than or equal to the depth of the corresponding mounting through hole.

[0014] Furthermore, at least one of the two magnetic members is fixed to the corresponding component through a bracket.

[0015] Furthermore, the bracket includes a frame and a fixing ear fixed on at least one side of the frame, the frame encloses a fixing space for fixing the magnetic component, and the fixing ear is fixed on the component.

[0016] Furthermore, the bracket also includes a limiting structure fixed on a side of the frame away from the component to limit the magnetic component.

[0017] Furthermore, at least one of the two magnetic members is bonded or welded to a corresponding component.

[0018] The present invention further provides a range hood, comprising: the above-mentioned disassembly and assembly structure.

[0019] Further, the fixed component is a smoke collecting hood, the detachable component is an air inlet hood, the smoke collecting hood has an installation cavity, and the air inlet hood is located in the installation cavity.

[0020] The technical solution of the present invention has the following advantages: magnetic parts are provided on both components, one of the two components has an installation cavity, and at least a part of the other of the two components is located in the installation cavity. When installing the detachable component, the detachable component is subjected to a force toward the fixed component, and the detachable component is pressed against the fixed component by the repulsive force between the two magnetic parts, thereby fixing the detachable component on the fixed component; when removing the detachable component, the detachable component is pulled a short distance away from the fixed component, and the direction of the force applied to the detachable component changes from toward the fixed component to away from the fixed component. Compared with the method in the prior art in which the air inlet cover and the guide plate are fixedly connected by magnetic attraction, the above structure does not require direct contact between the two magnetic parts, and the force is generated by the spatial magnetic field of the two magnetic parts, so the strength and feel are better during disassembly.

[0034] The technical solution of the present invention will be described clearly and completely below 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. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0037] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0038] like Figure 1 As shown, the disassembly and assembly structure of this embodiment includes two components, both of which are provided with magnetic parts. The two components are respectively a fixed component and a detachable component. The fixed component has an installation cavity 11, and the detachable component is located in the installation cavity 11. The detachable component is pressed onto the fixed component by the repulsive force between the two magnetic parts to fix the detachable component.

[0039] When the disassembly and assembly structure of the present embodiment is applied, magnetic parts are provided on both the fixed part and the detachable part. When installing the detachable part, after the detachable part is pushed into the installation cavity 11, the detachable part is subjected to a force toward the fixed part, and the detachable part is pressed against the fixed part by the repulsive force between the two magnetic parts, thereby fixing the detachable part on the fixed part; when removing the detachable part, the detachable part is pulled a short distance away from the fixed part, and the direction of the force applied to the detachable part is changed from toward the fixed part to away from the fixed part. Compared with the method in the prior art in which the air inlet hood and the guide plate are fixedly connected by magnetic attraction, the above structure does not require direct contact between the two magnetic parts, and the force is generated by the spatial magnetic field of the two magnetic parts, so the strength and feel are better during disassembly.

[0040] In this embodiment, if Figure 2 and Figure 3 As shown, when the detachable component is in a fixed state, the two magnetic components are staggered and the same poles of the two magnetic components are arranged opposite to each other, that is, the N poles of the two magnetic components are opposite to each other and the S poles of the two magnetic components are opposite to each other. Specifically, the connection direction of the N poles and S poles of the two magnetic components is perpendicular to the installation direction of the detachable component. Of course, the connection direction of the N poles and S poles of the magnetic components may not be perpendicular to the installation direction of the detachable component, that is, the connection direction of the N poles and S poles of the magnetic components has an obtuse angle or an acute angle with the installation direction of the detachable component.

[0041] In this embodiment, the two magnetic members are staggered along the installation direction of the detachable component, which facilitates the setting of the positions of the two magnetic members. Of course, the two magnetic members can also be staggered in three-dimensional space.

[0042] In this embodiment, the two magnetic members are respectively a first magnetic member 31 and a second magnetic member 32 . The first magnetic member 31 is disposed on the fixed member, and the second magnetic member 32 is disposed on the detachable member.

[0043] In this embodiment, the second magnetic member 32 is provided on the part of the detachable component that matches the peripheral wall of the installation cavity 11. Of course, the second magnetic member 32 can also be provided at other positions of the detachable component, as long as the detachable component can be subjected to a force acting toward the fixed component.

[0044] In this embodiment, a first magnetic member 31 is disposed on the peripheral wall of the installation cavity 11. Of course, the first magnetic member 31 may also be disposed at other positions of the fixed component, as long as the detachable component is subjected to a force acting toward the fixed component.

[0045] In this embodiment, when the detachable component is in a fixed state, there is a gap between the first magnetic component 31 and the second magnetic component 32 in a direction perpendicular to the installation direction of the detachable component. In this way, the magnitude of the repulsive force can be adjusted by adjusting the gap between the two magnetic components, and then the disassembly and assembly force can be adjusted, further ensuring that the force and feel are appropriate during disassembly and assembly. Specifically, the gap is in the range of 0.5 to 1.5 mm. Of course, the gap is not limited to this, and needs to be adjusted according to the weight of the detachable component and the user's disassembly and assembly requirements.

[0046] In this embodiment, if Figures 4 to 7 and Fig.10 As shown, both the fixed component and the detachable component are provided with mounting through holes, and the first magnetic component 31 and the second magnetic component 32 are fixed on the inner side of the corresponding component and both have protrusions 33 extending into the corresponding mounting through holes. Specifically, the mounting through hole on the fixed component is an open hole 12, that is, a complete hole, and the mounting through hole on the detachable component is a missing hole 21. Of course, the mounting through hole on the detachable component can also be a complete hole.

[0047] In this embodiment, if Figure 3 As shown, the first magnetic member 31 and the second magnetic member 32 have protrusions 33 on opposite sides. Of course, the protrusion may also be provided only on the side of the magnetic member facing the component.

[0048] In this embodiment, the thickness of the protrusion 33 of the first magnetic member 31 extending into the opening 12 is greater than or equal to the depth of the opening 12. It is convenient to adjust the gap between the two magnetic members, and then adjust the disassembly and assembly strength. The thickness of the protrusion 33 of the second magnetic member 32 extending into the missing hole 21 is less than or equal to the depth of the missing hole 21. It is convenient to adjust the gap between the two magnetic members, and then adjust the disassembly and assembly strength.

[0049] In this embodiment, the first magnetic member 31 and the second magnetic member 32 are fixed to corresponding components through the bracket 40 respectively, and the fixation is firm and reliable.

[0050] In this embodiment, if Figures 4 to 9 As shown, the bracket 40 includes a frame 41 and fixing ears 42 fixed on opposite sides of the frame 41. The frame 41 encloses a fixing space for fixing the magnetic member, and the fixing ears 42 are fixed on the component. The bracket 40 has a simple structure, is more firmly and reliably fixed, and is also convenient for fixing the bracket on the component. Figure 5 , Figure 7 and Fig.10 As shown, the fixing ears 42 are fixed on the component by fixing screws 44, which are easy to use and simple to connect. Of course, the number and position of the fixing ears are not limited to this and need to be selected according to specific circumstances.

[0051] In this embodiment, the bracket 40 further includes a limiting structure 43 fixed to a side of the frame 41 away from the component to limit the magnetic component and prevent the magnetic component from sliding out of the fixed space. The surrounding portion of the component located at the mounting through hole and the limiting structure 43 cooperate to limit the opposite sides of the magnetic component to prevent the magnetic component from sliding out of the fixed space, and the fixing is more secure.

[0052] In this embodiment, the first magnetic member 31 and the second magnetic member 32 are both magnets, which are easy to use. In this embodiment, the magnitude of the repulsive force is adjusted by adjusting the magnetic strength of the first magnetic member 31 and the second magnetic member 32, thereby adjusting the disassembly force during disassembly.

[0053] As an alternative embodiment, part of the detachable component is located in the installation cavity 11 and forms a fitting portion.

[0054] As an alternative embodiment, the detachable component has a mounting cavity, and at least a portion of the fixed component is located in the mounting cavity.

[0055] As an alternative implementation, at least one of the two magnetic members is bonded or welded to the corresponding component. Of course, the two magnetic members can also be fixed by other fixing methods, and are not limited thereto.

[0056] The present invention also provides a range hood, comprising: the above-mentioned disassembly and assembly structure.

[0057] In this embodiment, the range hood is a side suction range hood. In this embodiment, the fixed component is a fume hood 10, and the detachable component is an air inlet hood 20. The fume hood 10 has a mounting cavity 11, and the air inlet hood 20 is located in the mounting cavity 11. The first magnetic member 31 is fixed on the top wall of the mounting cavity 11, and the second magnetic member 32 is arranged on the upper edge 22 of the air inlet hood 20. Of course, the range hood can also be a top suction range hood, a tower range hood, an L-shaped range hood, or other forms of range hoods.

[0058] As an alternative implementation, the detachable component may also be an oil cup or other structure that needs to be frequently disassembled and assembled.

[0059] Combine the following Figure 3 The following describes the disassembly and assembly process of the air inlet cover:

[0060] When installing the air inlet hood 20, first insert the plug on the lower part of the air inlet hood 20 into the plug hole at the lower part of the smoke hood 10, and then push the upper part of the air inlet hood 20 into the installation cavity of the smoke hood 10. During the pushing process, under the action of the repulsive force between the first magnetic part 31 and the second magnetic part 32, the air inlet hood 20 is first subjected to a force in the direction away from the smoke hood 10. When the external pushing force is greater than the force acting on the air inlet hood 20 away from the smoke hood 10, the air inlet hood 10 is pushed into the installation cavity. When the second magnetic part 32 is located on the inner side of the first magnetic part 31, the air inlet hood 20 is subjected to a force in the direction toward the smoke hood 10, and then the upper part of the air inlet hood 20 and the upper part of the installation cavity are pressed into the smoke hood by the repulsive force between the same magnetic poles, thereby completing the fixed installation of the air inlet hood.

[0061] When disassembling the air inlet cover 20, first pull the upper part of the air inlet cover 20 away from the upper part of the smoke collecting hood 10 for a distance, and then pull the lower part of the air inlet cover 20 out of the lower part of the smoke collecting hood 10 to complete the disassembly.

[0062] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0063] The air inlet cover is disassembled and assembled by arranging two magnets with the same poles facing each other and staggered. The two magnets are not directly attracted to each other, but the force is generated by the magnetic field in the space between the two magnets. The force condition of the air inlet cover is better during disassembly and assembly, the disassembly and assembly force is adjustable, the hand feel is better, the disassembly and assembly is more convenient, and it is safe and reliable.

[0064] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
