Description

Technical Field

[0001] This utility model relates to a gas stove accessory, specifically a gas burner head damper blade. Background Technology

[0002] The gas burner head is the core component of both household and commercial gas stoves, and its performance directly affects combustion efficiency and safety. The damper blade, as an important part of the gas burner head, is mainly used to regulate the air-gas mixture ratio to achieve complete combustion and reduce the emission of harmful gases. However, existing damper blades have a series of design and application defects that limit performance improvements and increase production costs.

[0003] In existing technologies, the handle design of damper blades often suffers from being too long. This excessively long handle not only increases material usage, leading to higher production costs, but also easily interferes with the gas stove's base during installation. For example, in some known designs, the handle length exceeds practical needs, causing contact with the base or countertop during assembly, affecting assembly efficiency and compromising the overall structural compactness and aesthetics. Furthermore, the excessively long handle design can cause uneven force distribution on the damper blades during operation, generating additional stress and further reducing their lifespan.

[0004] Another common problem is the lack of an effective positioning structure for existing damper blades. When adjusting airflow, the damper plate is difficult to fix in place and is prone to displacement due to external vibrations, accidental user contact, or loosening after prolonged use. This displacement leads to an imbalance in the air-fuel mixture ratio, affecting combustion efficiency and potentially causing safety hazards due to gas leaks or incomplete combustion. Some existing technologies attempt to solve this problem by adding additional fasteners, but this often complicates the structure, increases manufacturing difficulty and production costs, thus necessitating further improvements. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a gas burner damper blade that is simple in structure, easy to use, has high material utilization, and has an effective positioning function, thereby overcoming the deficiencies of existing technologies and improving the overall performance and economy of the gas burner.

[0006] The purpose of this utility model is achieved in the following way: a gas burner head damper blade, including a central seat, a first cover plate and a second cover plate in a fan shape are respectively provided on both sides of the central seat, a baffle plate extends outward from the outer edge of the second cover plate, the baffle plate has a rear end face, and a baffle platform is provided on the rear end face protruding outward.

[0007] The gear shift plate is also provided with a drive handle, which is formed by bending the front end of the gear shift plate outward.

[0008] Furthermore, the first cover plate and the second cover plate are provided with reinforcing ribs protruding towards their front end faces.

[0009] Furthermore, the reinforcing rib extends radially outward from the central seat.

[0010] Furthermore, the stop plate is also provided with reinforcing ribs, and the reinforcing ribs on the stop plate are connected to the reinforcing ribs on the second cover plate.

[0011] Furthermore, the stop platform is an arc-shaped protrusion formed by stamping the body material of the stop plate towards the rear end face.

[0012] Furthermore, the outer surface of the drive handle is provided with several recessed anti-slip grooves.

[0013] Furthermore, the center seat, first cover plate, second cover plate, stop plate, stop platform, and drive handle are integrally stamped from metal sheet.

[0014] The beneficial effects of this utility model are: 1. Simple structure, low production cost, and improved market competitiveness.

[0015] This invention significantly shortens the length of the adjustment handle by designing the drive handle to be bent outwards from the front end of the stop plate. Compared to the excessively long handles in traditional designs, this improvement effectively avoids contact between the handle and the table surface, improving operational convenience, while also reducing the amount of metal sheet used and significantly lowering production costs.

[0016] 3. Traditional damper blade handles are often too long, making them prone to contacting the countertop during installation or use, affecting the overall aesthetics of the gas stove and the operating space. This invention optimizes the bending design of the handle, keeping its length within a reasonable range and ensuring a safe distance between the handle and the countertop, thereby improving user comfort and the applicability of the gas stove.

[0017] This invention reduces raw material consumption by shortening the drive handle and optimizing the overall structural layout while ensuring functionality. Compared with existing technologies, this design not only reduces manufacturing costs but also meets the economic and environmental requirements of modern industrial design, bringing greater economic benefits to manufacturers.

[0018] In existing technologies, excessively long handles often cause interference with the gas stove's bottom shell during assembly, increasing assembly difficulty and affecting the structural compactness. The drive handle of this invention is formed by bending from the front face of the stop plate, optimizing the handle's position and orientation, ensuring sufficient clearance between it and the bottom shell, effectively avoiding interference problems, thereby improving assembly efficiency and the overall design rationality.

[0020] Figure 2 , 3 This is a schematic diagram of the structure of this utility model. Detailed Implementation

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. A gas burner head damper blade includes a center seat 1, on both sides of the center seat 1 respectively provided a fan-shaped first cover plate 2 and a second cover plate 3, the outer edge of the second cover plate 3 extends outward with a baffle plate 4, the baffle plate 4 has a rear end face, and a baffle platform 5 is provided protruding outward from the rear end face;

[0022] The gear shift plate 4 is also provided with a drive handle 6, which is formed by bending the front end of the gear shift plate 4 outward.

[0023] In this embodiment, the gas burner head damper blades are supported by a central base 1, connecting a first cover plate 2 and a second cover plate 3 on both sides. The two cover plates are fan-shaped, allowing for adjustment of their opening angle by rotation, thereby controlling the air intake of the gas burner head and achieving proper mixing of air and gas. A baffle plate 4 extends outward from the outer edge of the second cover plate 3, and its rear end face has a baffle platform 5 that engages with an external device such as a slot via a protruding structure to fix the damper blades in a specific position. A drive handle 6 is formed by bending the front end of the baffle plate 4 outward. By holding and rotating the drive handle 6, the user rotates the entire damper blade, thereby adjusting the opening degree of the cover plates to meet different combustion requirements.

[0024] Compared to traditional technologies, the drive handle 6 is formed by bending the front end of the stop plate 4 outwards. Compared to the traditional excessively long handle design, this invention significantly shortens the handle length, avoiding problems such as contact with the table surface or interference with the bottom shell, thus improving assembly efficiency and ease of operation. At the same time, the shortened handle length reduces the amount of metal sheet used, lowering production costs and meeting economic requirements. Furthermore, the raised design of the stop plate 5 provides a stable positioning structure, ensuring that the damper blades are not easily displaced due to vibration or accidental contact after adjustment, enhancing safety during use.

[0025] In one embodiment, the first cover plate 2 and the second cover plate 3 are provided with reinforcing ribs 7 protruding towards their front ends. In this embodiment, the reinforcing ribs 7 protruding towards their front ends on the first cover plate 2 and the second cover plate 3 increase the rigidity and deformation resistance of the cover plates by increasing the local thickness. During frequent rotation and adjustment of the damper blades or long-term use, the cover plates may bend or deform due to stress. The reinforcing ribs 7 can effectively resist these external forces, maintain the shape stability of the cover plates, and thus ensure accurate adjustment of the air intake and continuous combustion efficiency. The reinforcing ribs 7 enhance the durability of the cover plates, extend the service life of the damper blades, and reduce functional failures caused by deformation. At the same time, the stable cover plate shape ensures the accuracy of the damper blades during adjustment and avoids air intake fluctuations caused by structural deformation.

[0026] In one embodiment, the reinforcing rib 7 extends radially outward from the central seat 1. The reinforcing rib 7 extends radially outward from the central seat 1 and is distributed along the direction of the fan-shaped cover plate. This design allows the reinforcing rib 7 to evenly distribute the stress borne by the cover plate during rotational adjustment. Especially under torsional forces, the reinforcing rib 7 effectively prevents deformation or breakage of the cover plate, ensuring the overall structural stability of the damper blades and the smoothness of the adjustment process. Simultaneously, the radially extending reinforcing rib 7 improves the torsional resistance of the cover plate and enhances structural stability. Uniform stress distribution reduces the risk of localized fatigue damage and improves the durability of the damper blades.

[0027] In one embodiment, the stop plate 4 is also provided with a reinforcing rib 7, and the reinforcing rib 7 on the stop plate 4 is connected to the reinforcing rib 7 on the second cover plate 3.

[0028] In this embodiment, the reinforcing ribs 7 on the damper plate 4 are connected to the reinforcing ribs 7 on the second cover plate 3, forming a continuous reinforcing structure. This design not only enhances the rigidity of the damper plate 4 itself, but also improves the overall structural strength of the damper blade through its connection with the cover plate. When the user operates the drive handle 6 to rotate the damper blade, the damper plate 4 bears a large operating force. The connected design of the reinforcing ribs 7 effectively prevents it from deforming due to the force, ensuring the stability of the adjustment function.

[0029] In one embodiment, the baffle platform 5 is an arc-shaped protrusion formed by stamping the body material of the baffle plate 4 towards the rear end face. The baffle platform 5 is formed into an arc-shaped protrusion from the body material of the baffle plate 4 towards the rear end face through a stamping process, and is integrally formed with the baffle plate 4 without additional welding or assembly steps. During the rotation adjustment of the damper blades, the arc-shaped protrusion of the baffle platform 5 can engage with external devices to lock the position of the damper blades, preventing them from shifting due to external interference after adjustment, thereby ensuring the stability of the air intake volume.

[0030] In this embodiment, the arc-shaped protruding stop platform 5 provides an effective positioning function, ensuring that the damper blades are stably fixed at different opening and closing angles, avoiding the defect of easy displacement of the damper plate in the prior art. At the same time, the one-piece stamping process simplifies the production process, reduces manufacturing costs, and ensures the strength and consistency of the structure.

[0031] In one embodiment, the outer surface of the drive handle 6 is provided with several recessed anti-slip grooves 8. These anti-slip grooves increase surface roughness and friction, allowing the user to grip and apply force more firmly when operating the handle. Whether in a wet environment or with oily hands, the anti-slip grooves 8 effectively prevent hand slippage, ensuring the accuracy and safety of rotational adjustment. At the same time, the anti-slip design reduces the possibility of operational errors, ensuring the stability and reliability of the adjustment process.

[0032] In one embodiment, the center seat 1, first cover plate 2, second cover plate 3, stop plate 4, stop platform 5, and drive handle 6 are integrally stamped from sheet metal. The entire damper blade—including the center seat 1, first cover plate 2, second cover plate 3, stop plate 4, stop platform 5, and drive handle 6—is manufactured using an integral sheet metal stamping process, completing the forming and connection of all components in a single stamping process. This process avoids the need for subsequent welding or assembly, ensuring seamless connection between components and the stability of the overall structure, while also improving production efficiency.

[0033] In summary, the gas burner head damper blade of this utility model is centered on the central seat 1, connecting the first cover plate 2 and the second cover plate 3, which are fan-shaped on both sides. The air intake volume is controlled by rotating and adjusting the opening and closing angle of the cover plates. A stop plate 4 extending from the outer edge of the second cover plate 3 has a stop platform 5 on its rear end face, which cooperates with an external device through an arc-shaped protrusion to achieve the positioning and fixation of the damper blade. The drive handle 6 is formed by bending the front end of the stop plate 4 outwards, allowing the user to adjust the damper position by rotating the handle. Reinforcing ribs 7 are distributed on the first cover plate 2, the second cover plate 3, and the stop plate 4, and are interconnected, enhancing the rigidity and durability of the overall structure. The anti-slip groove 8 on the outer surface of the drive handle 6 improves the convenience and safety of operation. The entire damper blade is integrally stamped from a metal sheet, resulting in efficient processing and a stable structure.

[0034] Compared to existing technologies, this invention saves materials by shortening the length of the drive handle, avoiding contact with the table surface and interference with the bottom shell; the gear shift platform 5 provides a positioning function, solving the problem of easy displacement of the damper plate; the reinforcing rib 7 and the one-piece molding process further improve structural strength and production efficiency. The overall design achieves the technical effects of compact structure, convenient operation, material saving, high stability and excellent economy, and therefore can be widely promoted and used.

[0035] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this utility model.
