Description

Technical Field

[0001] This utility model relates to the field of range hood technology, and in particular to a quick-release range hood oil collection box installation structure. Background Technology

[0002] Existing side-suction range hoods, such as Figures 1-3 As shown, the range hood includes a body 1 and an oil collection box 2 located below it. The oil collection box 2 is a long rectangular strip with an opening at the top. An oil leakage hole 1-1 is provided in the oil collection box 2 at the lower end of the range hood body 1. Horizontally extending plug-in pieces 2-1 are symmetrically provided on both sides of the opening end of the oil collection box 2. The plug-in pieces 2-1 extend horizontally in opposite directions from the two side walls of the opening end. A buckle assembly 1-2 is provided at a corresponding position on the lower end face of the range hood body 1. The buckle assembly 1-2 includes a hook 1-2.1 that cooperates with the plug-in piece 2-1. A gap is left between the hook 1-2.1 and the range hood body 1 for the plug-in piece 2-1 to be inserted. A mounting seat 1-2.2 is provided on the side of the hook 1-2.1. The mounting seat 1-2.2 is fixedly connected to the lower end face of the range hood body 1. The hook 1-2.1 and the mounting seat 1-2.2 are connected by a transition connecting piece 1-2.3. After installation, the rear sides of both the range hood body 1 and the oil collection box 2 are flush with the wall. The end of the hook 1-2.1 away from the wall is bent downwards to assist in the alignment operation during installation.

[0003] The existing side-suction range hood's oil collection box 2 presents significant inconvenience during disassembly and assembly. The specific reasons are as follows: Firstly, since the range hood body 1 and the oil collection box 2 are both attached to the wall after installation, users can only hold the two side walls of the oil collection box 2 when disassembling it. This holding position lacks a natural fulcrum for applying force, and the contact area between the hand and the oil collection box 2 is limited, which makes it easy to slip or apply force unevenly when exerting force, making it difficult to operate stably.

[0004] Secondly, both the connector 2-1 and the snap fastener 1-2 are exposed above the opening of the oil collection box 2. When cooking, the grease in the oil collection box 2 evaporates at high temperature, and the grease in the fumes easily adheres to the surface of the connector 2-1 and the snap fastener 1-2. After long-term use, grease will accumulate, which will increase the frictional resistance between the two when disassembling.

[0005] Thirdly, the oil collection box 2 is connected to the hook 1-2.1 by symmetrical plug-in pieces 2-1 on both sides. If the force applied on both sides is uneven during disassembly, it is easy to cause the separation progress of the two ends to be inconsistent, which in turn causes the plug-in structure to jam.

[0006] Fourth, although the end of the hook 1-2.1 away from the wall is designed to be bent downwards to assist in installation and alignment, since the entire buckle assembly 1-2 is located on the lower end face of the range hood body 1, and the plug-in piece 2-1 at the opening end of the oil collection box 2 extends horizontally, the oil collection box 2 needs to be close to the lower end face of the body to achieve docking during installation. At this time, the mating part of the plug-in piece 2-1 and the hook 1-2.1 is blocked, and the user cannot directly observe the docking status, resulting in difficulty in alignment. Utility Model Content

[0007] To address the aforementioned problems, the purpose of this utility model is to provide a quick-release oil collection box installation structure for range hoods, thereby solving the problems of inconvenient gripping and force application, and difficulty in alignment during installation, which exist in the prior art during the disassembly and assembly of oil collection boxes.

[0008] The technical solution of this utility model is as follows: A quick-release oil collection box installation structure for a range hood includes a range hood body and an oil collection box located below it. The rear end face of the oil collection box has symmetrical notches along its length for applying force with a hand; the notches extend along the width of the oil collection box, and the depth of the notches is sufficient for fingers to be inserted. A horizontal mounting notch is recessed on the end face of the notch.

[0009] The installation notch is equipped with a control mechanism, which includes an elastic sheet. The elastic sheet is vertically arranged and connected to the end face of the installation notch, with a deformation gap between them. A control rod is horizontally connected to the elastic sheet, and a button is connected to the end of the control rod away from the elastic sheet.

[0010] A locking post is radially protruding on the control rod located between the button and the elastic sheet; a vertical locking piece is provided at the lower end of the range hood body, and an L-shaped locking groove is opened on the locking piece to cooperate with the locking post; the vertical section of the L-shaped locking groove is open, and the locking post is engaged with the horizontal section of the locking groove.

[0011] Furthermore, the installation notch opening includes an upper end, a lower end, and a rear end away from the front end of the oil collection box. An integrally formed cover plate is provided at the opening, and a through hole is formed on the rear cover plate. The control rod passes through the through hole and is connected to a button within the notch. The cover plate forms a closed protective enclosure for the control mechanism within the installation notch, reducing direct intrusion of oil fumes. The through hole of the rear cover plate and the control rod are clearance-fitted, providing axial guidance for the control rod's movement and constraining its radial wobble through the hole wall, ensuring the alignment accuracy of the locking pin and the locking slot.

[0012] Furthermore, the upper cover plate has symmetrical arc-shaped guide pieces that extend into the mounting notch to above the locking post. The two arc-shaped guide pieces form a guide channel with a thickness matching that of the locking piece. During installation, the locking piece is first guided through the guide channel and slides along the arc-shaped surface to the mating area between the locking post and the L-shaped slot, facilitating installation and alignment.

[0013] Furthermore, a connecting seat is provided on the end face of the mounting notch. The connecting seat includes a fitting section that fits the end face of the mounting notch, an installation section located within the mounting notch, and a transition section connecting the upper end of the fitting section and the lower end of the installation section. The fitting section and the installation section are parallel and spaced apart. The elastic sheet is installed on the installation section.

[0014] Furthermore, the elastic sheet and the control rod are specifically connected by a rotational connection, with the rotation axis perpendicular to the length direction of the control rod. When the elastic sheet bends and deforms, the rotational connection can adapt to its arc-shaped motion trajectory, avoiding the control rod swaying caused by the rigid connection. Combined with the constraint of the through hole in the cover plate, the control rod always moves in an approximately horizontal direction, ensuring accurate movement of the locking pin and lossless force transmission.

[0015] Furthermore, the vertical section of the L-shaped slot is provided with a guide slope, the slope of which is adapted to the entry angle of the locking post. During installation, the locking post contacts the guide slope and generates a lateral force, which can push the elastic plate to deform so that it is locked into the vertical section of the L-shaped slot. The locking post can automatically calibrate its position along the slope without pressing a button, achieving locking without operational intervention.

[0016] Furthermore, the button and the control lever are connected by threads. During assembly, the control lever is first pre-installed in the mounting notch and passes through the cover plate through hole, and then the button is tightened from the outside to avoid assembly interference and facilitate the individual disassembly and replacement of the button.

[0017] The beneficial effects of this utility model are as follows: 1. In this utility model, the oil collection box has symmetrical notches along the length direction on the rear end face, which extend along the width direction and are deep enough to fit the fingers, providing a stable force fulcrum for hand operation, increasing the contact area between the hand and the oil collection box, improving the stability when holding, and reducing slippage or uneven force application.

[0018] 2. The elastic sheet and the control rod of this utility model are connected by rotation (the axis of rotation is perpendicular to the length direction of the control rod). With the radial constraint of the control rod by the through hole of the cover plate, the control rod can move stably in an approximately horizontal direction, which is compatible with the arc trajectory when the elastic sheet bends, avoids the control rod swaying caused by rigid connection, and improves the stability of force transmission.

[0019] 3. In this utility model, the symmetrical arc-shaped guide piece on the upper end cover plate extends into the installation notch to the top of the locking post, forming a guide channel that matches the thickness of the locking piece. This guides the locking piece to slide precisely into the mating area of ​​the locking post and the L-shaped locking groove along the arc surface, reducing alignment deviation during installation and improving installation efficiency.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] like Figures 1 to 7 As shown, a quick-release range hood oil collection box installation structure includes a range hood body 1 and an oil collection box 2 located below it. The rear end face of the oil collection box 2 has symmetrically formed notches 2-2 along its length for applying force with a hand; the notches 2-2 extend along the width of the oil collection box 2, and their depth is sufficient for a finger to be inserted. A horizontal mounting notch is recessed on the end face of the notch 2-2 near the front end of the oil collection box 2.

[0030] The installation notch is equipped with a control mechanism 3, which includes an elastic sheet 3-1. The elastic sheet 3-1 is vertically arranged and connected to the end face of the installation notch, with a deformation gap between them. A control rod 3-2 is horizontally connected to the elastic sheet 3-1, and a button 3-3 is connected to the end of the control rod 3-2 away from the elastic sheet 3-1.

[0031] A locking post 3-2.1 is radially protruding on the control rod 3-2 located between the button 3-3 and the elastic piece 3-1; a vertical locking piece 1-3 is provided at the lower end of the range hood body 1, and an L-shaped locking groove 1-3.1 is opened on the locking piece 1-3 to cooperate with the locking post 3-2.1; the vertical section of the L-shaped locking groove 1-3.1 is open, and the locking post 3-2.1 is engaged with the horizontal section of the locking groove.

[0032] Furthermore, the installation notch opening includes an upper end, a lower end, and a rear end away from the front end of the oil collection box 2. An integrally formed cover plate 4 is provided at the opening. A through hole is formed on the cover plate 4 at the rear end. The control rod 3-2 passes through the through hole and is connected to a button 3-3 within the notch 2-2. The cover plate 4 forms a closed protective enclosure for the control mechanism 3 within the installation notch, reducing direct intrusion of oil fumes. The through hole of the rear cover plate 4 and the control rod 3-2 are clearance-fitted, providing axial guidance for the control rod 3-2 and constraining its radial movement through the hole wall, ensuring the alignment accuracy of the locking post 3-2.1 and the locking slot.

[0033] Furthermore, the upper cover plate 4 has symmetrical arc-shaped guide pieces 4-1. The arc-shaped guide pieces 4-1 extend into the mounting notch to above the locking post 3-2.1, and the two arc-shaped guide pieces 4-1 form a guide channel that matches the thickness of the locking piece 1-3. During installation, the locking piece 1-3 is first guided through the guide channel and slides along the arc-shaped surface to the mating area between the locking post 3-2.1 and the L-shaped slot 1-3.1, facilitating installation alignment.

[0034] Furthermore, a connecting seat 5 is provided on the end face of the mounting notch. The connecting seat 5 includes a fitting section 5-1 that fits into the end face of the mounting notch, an installation section 5-2 located within the mounting notch, and a transition section 5-3 that connects the upper end of the fitting section 5-1 and the lower end of the installation section 5-2. The fitting section 5-1 and the installation section 5-2 are parallel and spaced apart. An elastic sheet 3-1 is installed on the installation section 5-2.

[0035] Furthermore, the elastic plate 3-1 and the control rod 3-2 are specifically connected by a rotation, with the rotation axis perpendicular to the length direction of the control rod 3-2. When the elastic plate 3-1 bends and deforms, the rotation connection can adapt to its arc-shaped motion trajectory, avoiding the swaying of the control rod 3-2 caused by the rigid connection. With the constraint of the through hole of the cover plate 4, the control rod 3-2 always moves in an approximately horizontal direction, ensuring that the movement of the locking pin 3-2.1 is accurate and the force transmission is lossless.

[0036] Furthermore, the vertical section opening of the L-shaped slot 1-3.1 is provided with a guide slope 1-3.1.1, the slope of which is adapted to the entry angle of the locking post 3-2.1. During installation, the locking post 3-2.1 contacts the guide slope 1-3.1.1 and generates a lateral force, which can push the elastic plate 3-1 to deform so that the locking post 3-2.1 enters the vertical section of the L-shaped slot 1-3.1. The locking post 3-2.1 can automatically calibrate its position along the slope without pressing the button 3-3, achieving locking without operational intervention.

[0037] Furthermore, the button 3-3 and the control lever 3-2 are connected by threads. During assembly, the control lever 3-2 is first pre-installed in the mounting notch and passes through the through hole of the cover plate 4, and then the button 3-3 is tightened from the outside to avoid assembly interference and facilitate the individual disassembly and replacement of the button 3-3.

[0038] Working principle of this utility model: I. Installation Phase: 1. Hold and lift the oil collection box 2 with both hands through the symmetrical notch 2-2 on the rear end face of the oil collection box 2, so that the snap-fit ​​piece 1-3 is aligned with the guide channel formed by the arc-shaped guide piece 4-1.

[0039] 2. The snap-fit ​​piece 1-3 slides into the installation notch along the curved surface of the arc-shaped guide piece 4-1, and its front end contacts the guide slope 1-3.1.1 of the L-shaped slot 1-3.1.

[0040] 3. The locking pin 3-2.1 moves upward with the oil collection box 2 and comes into contact with the guide slope 1-3.1.1. The lateral force of the slope pushes the control rod 3-2, causing the elastic plate 3-1 to bend towards the deformation gap (no need to press the button 3-3), which in turn causes the locking pin 3-2.1 to move.

[0041] 4. The locking post 3-2.1 slides into the vertical section of the L-shaped slot 1-3.1 along the inclined surface. When it continues to move upward to the entrance of the horizontal section, the rebound force of the elastic plate 3-1 pushes the locking post 3-2.1 into the horizontal section, forming a rigid engagement with the inner wall of the slot, thus completing the installation and locking.

[0042] II. Disassembly Stage: 1. Insert your finger into the notch 2-2 to hold the oil collection box 2 and press the button 3-3. The control lever 3-2 moves horizontally, causing the locking pin 3-2.1 to slide from the horizontal section of the L-shaped slot 1-3.1 to the connection between the horizontal and vertical sections.

[0043] 2. After the locking post 3-2.1 slides to the connection between the horizontal and vertical sections, apply force by hand to pull down the oil collection box 2. The locking post 3-2.1 will descend along the vertical section of the L-shaped locking groove 1-3.1 to the opening.

[0044] 3. The snap-fit ​​piece 1-3 slides out of the guide channel in the opposite direction along the curved surface of the arc-shaped guide piece 4-1 to complete the disassembly. The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
