Description

Technical Field

[0001] This utility model relates to the field of range hoods, and specifically to a range hood adjustment mechanism. Background Technology

[0002] A range hood, also known as a cooking hood, is a kitchen appliance used to purify the kitchen environment. Installed above the stove, it quickly removes waste from combustion and harmful fumes produced during cooking, expelling them outdoors. It also condenses and collects these fumes, reducing pollution, purifying the air, and providing safety features such as protection against toxic substances and explosions.

[0003] The range hood is installed directly above the cooktop. Whether it's a side-draft or top-draft type, after determining the installation location, use an impact drill to drill a hole 5-6cm deep at the installation location. Press the expansion tube into the hole, and then use screws to securely fix the mounting plate. The design of the back of the range hood can fit perfectly into the mounting plate, thus holding the range hood in place.

[0004] However, since many families' kitchen cabinets are not installed as a single unit with the range hood, there is a gap between the top of the range hood's suction chamber and the bottom of the cabinet. These gaps are not easy to clean and can easily breed insects and mold, leading to various hygiene problems.

[0005] However, the above installation method alone cannot effectively eliminate the gap. Therefore, the inventors conducted further research and developed a range hood adjustment mechanism, which led to this invention. Utility Model Content

[0006] The purpose of this utility model is to provide a range hood adjustment mechanism that allows for free adjustment of the range hood's height and makes installation and fixing more convenient.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows:

[0008] A range hood adjustment mechanism, including

[0009] The bracket has an L-shaped or T-shaped cross-section, and several through slots are provided on the horizontal folded edge of the bracket.

[0010] The bellows is located below the mounting bracket;

[0011] The lifting adjustment component is connected to the air box through a through slot and can change the relative height of the air box by its own lifting or length adjustment.

[0012] The bracket is usually installed on the wall. Since it is an L-shaped or T-shaped structure, there must be a horizontal folded edge. By opening a through groove on it, a lifting adjustment component can be installed. By adjusting the lifting adjustment component, the relative height of the bellows can be changed.

[0013] Furthermore, the bracket is equipped with two through slots.

[0014] The stability of the adjustment mechanism can be ensured by using two through slots spaced a certain distance apart.

[0015] Furthermore, the hanger is configured into a T-shaped structure by two L-shaped structures.

[0016] This type of bracket has a better structural strength.

[0017] Furthermore, the bracket includes an L-shaped upper bracket and a lower bracket, with their horizontal folded edges overlapping, and the horizontal folded edge of the upper bracket is provided with a retaining edge.

[0018] The presence of the guard can limit the height adjustment.

[0019] Furthermore, the groove on the upper bracket extends to the edge; the groove on the lower bracket is an open structure.

[0020] The above structure facilitates the installation of lifting and adjusting components.

[0021] Furthermore, the lifting adjustment component includes a screw, with an upper nut at the upper end and a lower nut at the lower end. The upper nut is located above the groove, and the lower nut is located inside the air box.

[0022] By adjusting the upper nut, the lower nut causes the bellows to rise and fall.

[0023] Furthermore, a limit nut is also provided below the groove.

[0024] Tighten the limit nut to secure it after the upper nut has been adjusted.

[0025] By adopting the above solution, this utility model has the following advantages compared with the prior art:

[0026] The height of the range hood's air box can be freely adjusted using the lifting adjustment mechanism, making the installation of the range hood more flexible and convenient. Attached Figure Description

[0027] Figure 1 This is a schematic diagram of the present invention;

[0028] Figure 2 yes Figure 1 A magnified view of a section at point A in the middle;

[0029] Label Explanation

[0030] Mounting bracket 1, upper mounting bracket 11, side guard 111, lower mounting bracket 12.

[0031] Adjusting screw 2, upper nut 21, limit nut 22,

[0032] Bellows 3. Detailed Implementation

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figure 1 , 2 As shown, a range hood adjustment mechanism is used in conjunction with the range hood's air box 3, including a bracket 1 and an adjustment screw 22. The bracket includes an L-shaped upper bracket 11 and a lower bracket 12, whose horizontal folded edges overlap to form a strip-shaped component with a T-shaped cross-section. The upper bracket 11 has mounting holes on its vertical side for mounting the bracket on the wall, and through slots on the left and right sides of its horizontal folded edge for mounting the adjustment screw 2. At the same time, the outer edge of the horizontal folded edge is folded upward to form a retaining edge 111.

[0035] A through slot is also provided at the corresponding position of the lower fixing plate. This through slot is also used to allow the adjusting screw 2 to pass through. The difference is that the opening of this through slot is an open structure, which facilitates the entry of the adjusting screw 2. The aforementioned retaining edge 111 can restrict the adjusting screw 2 in the horizontal direction.

[0036] The adjusting screw 2 has an upper nut 21 at its upper end and a lower nut at its lower end. The upper nut 21 is located above the groove, and the lower nut is located inside the bellows 3 (not visible in the figure). A reinforcing plate can be added at the location of the lower nut for structural reinforcement. At the same time, a limit nut 22 is set below the horizontal folded edge of the bracket. Adjusting the upper nut 21 can drive the lower nut to rise or fall, thereby raising or lowering the entire bellows. Once the position is determined, tightening the limit nut 22 completes the installation.

[0037] By utilizing the continuous adjustment capability of the adjusting screw 2, the bellows can be adjusted using simple tools without the need for a lifting motor, resulting in low operating costs and a simple structure.

[0038] The above are merely specific embodiments of this utility model. Furthermore, terms such as "upper," "lower," "left," "right," and "middle" used in this utility model are for reference only and are not absolute limitations. Any non-substantial modifications made to this utility model shall be considered as infringing upon the protection scope of this utility model.
