Description

Technical Field

[0001] This utility model relates to the field of stove technology, and in particular to a switch knob for stoves. Background Technology

[0002] The development of materials science has provided more options for optimizing switch knobs. Early switch knobs were mostly made of ordinary plastics or metals, with limited performance. Today, high-performance engineering plastics, corrosion-resistant and high-temperature resistant metal alloys are widely used, making switch knobs not only more durable and reliable, but also able to meet different environmental and usage requirements. Switch knobs are just simple mechanical devices used to control the on and off of gas. As people's living standards improve, the performance requirements for stoves are constantly increasing. From the initial pursuit of simply producing flames for cooking, there are now higher expectations for the precision of firepower adjustment, safety, and convenience.

[0003] Most existing switch knobs lack protective features. Children may turn the knobs out of curiosity, accidentally turning on the stove and causing gas leaks or even fires. Moreover, in daily kitchen operations, objects often collide with the knobs. Even a slight collision can change the knob's position, causing sudden changes in the flame intensity, affecting cooking results, and even causing dangers such as hot oil splattering and soup spills. Therefore, we propose a switch knob for stoves. Utility Model Content

[0004] The purpose of this utility model is to provide a switch knob for stoves to solve the problem that most existing switch knobs do not have a protective effect. Children may turn the knob at will out of curiosity, accidentally turning on the stove and causing gas leaks or even fires. Moreover, in daily kitchen operations, objects often collide with the knob. Even a slight collision may change the position of the knob, causing sudden changes in the heat, affecting the cooking effect, and even causing dangerous problems such as hot oil splashing and soup overflowing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a switch knob for a stove, comprising a knob body, a protective component on the outer side of the knob body, and a fixing component at the bottom of the protective component, an auxiliary component inside the knob body, the fixing component comprising a stabilizing suction cup, a damping sleeve fixedly mounted on the top of the stabilizing suction cup, and a circular groove formed on the outer circumferential surface of the damping sleeve, the protective component comprising multiple sets of sliders slidably connected in the circular groove, the multiple sets of sliders being connected to a transparent cover via a mounting base, threaded holes being formed through the surfaces of the mounting base and the sliders, and locking bolts being threadedly connected inside the threaded holes.

[0006] As a preferred embodiment, the knob body is disposed inside the damping sleeve and the mounting base, and a groove is provided on the upper side of the knob body.

[0007] As a preferred embodiment, the inner wall of the damping sleeve is provided with anti-slip texture, and the anti-slip texture is in contact with the outer surface of the knob body.

[0008] As a preferred embodiment, the inner wall of the mounting base is fixedly mounted on the surface of multiple sets of sliders, and the mounting base is hinged to the transparent cover. A limit hole is opened on the front side of the surface of the mounting base, and a limit post adapted to the limit hole is opened on the bottom front side of the transparent cover. An insulating pull block is fixedly mounted on the front circumferential surface of the transparent cover.

[0009] As a preferred embodiment, the auxiliary component includes a rotating shaft fixedly installed inside the bottom of the knob body, a metal sheet fixedly installed on the circumferential surface of the rotating shaft, and a damping rubber ring fixedly installed at the bottom of the metal sheet, the damping rubber ring being sleeved on the circumferential surface of the rotating shaft.

[0010] As a preferred embodiment, multiple sets of springs are fixedly installed between the surface of the metal sheet and the inner top surface of the knob body, and the multiple sets of springs are arranged at an angle.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] 1. By setting up fixing and protective components, first attach the stabilizing suction cup to the stove platform, then install the knob body so that the rotating shaft is connected to the stove components. At this time, the outer surface of the knob body is tightly fitted with the anti-slip texture of the inner wall of the damping sleeve. Rotate the mounting base to adjust it to a suitable position for the opening direction of the transparent cover, and then use the locking bolts to fix the mounting base and the damping sleeve. When opening or closing the transparent cover, the limiting hole and the limiting post cooperate with each other to store the knob body inside the transparent cover, effectively preventing children from operating it by mistake and avoiding danger caused by accidental opening of the stove. During cooking, after adjusting the fire level, cover the transparent cover to prevent oil stains from falling into the inside of the knob body and reduce cleaning problems.

[0013] 2. By setting auxiliary components, when the knob body rotates, its outer surface comes into contact with the anti-slip texture to generate friction. At the same time, the damping rubber ring fitted on the rotating shaft provides damping by utilizing the properties of rubber. In addition, one end of the spring is fixed to the top of the knob body, and the other end is connected to a metal plate integrally formed with the rotating shaft. When the knob body rotates, the metal plate squeezes the spring, and the spring generates a counterforce to form a damping sensation. Under the action of multiple damping, the knob body is not easy to rotate accidentally due to external force or slight vibration. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1:

[0024] Please see the appendix Figure 1 - Appendix Figure 6A switch knob for a stove includes a knob body 1, a protective component 2 on the outer side of the knob body 1, and a fixing component 3 at the bottom of the protective component 2. An auxiliary component 4 is located inside the knob body 1. The fixing component 3 includes a stabilizing suction cup 301, a damping sleeve 302 fixedly mounted on the top of the stabilizing suction cup 301, and a circular groove 303 formed on the outer circumferential surface of the damping sleeve 302. The protective component 2 includes multiple sets of sliders 205 slidably connected within the circular groove 303. The multiple sets of sliders 205 are connected to a transparent cover 202 via a mounting base 201. Threaded holes 206 are formed through the surfaces of both the mounting base 201 and the sliders 205, and the internal threads of the threaded holes 206 are threadedly connected to... The locking bolt 207, the knob body 1 is set inside the damping sleeve 302 and the mounting base 201, and the upper side of the knob body 1 is provided with a groove 5, which serves as an anti-slip function. The inner wall of the damping sleeve 302 is provided with anti-slip texture 304, and the anti-slip texture 304 is in contact with the outer surface of the knob body 1. The inner wall of the mounting base 201 is fixedly installed on the surface of multiple sets of sliders 205, and the mounting base 201 is hinged to the transparent cover 202. The front side of the surface of the mounting base 201 is provided with a limit insertion hole 203, and the bottom front side of the transparent cover 202 is provided with a limit insertion post 204 that matches the limit insertion hole 203. An insulating pull block 208 is fixedly installed on the front circumferential surface of the transparent cover 202.

[0025] A damping sleeve 302 made of high-friction rubber is designed. The inside of the damping sleeve 302 has anti-slip texture 304 that is adapted to the knob body 1 to ensure sufficient damping effect without affecting operation. The suction cup 301 is installed on the stove countertop, which is convenient for installation and removal. At the same time, it can prevent oil stains from entering the stove through the gap between the knob body 1 and the stove. Depending on the stove or usage habits, the position of the transparent cover 202 after opening can be adjusted by rotating the mounting base 201. Then, the locking bolt 207 passes through the mounting base 201, the slider 205 and the damping sleeve 302 to fix it completely.

[0026] Specifically, first, attach the stabilizing suction cup 301 to the stove platform, then install the knob body 1 and connect the rotating shaft 401 to the corresponding connecting parts of the stove. At this time, the outer surface of the knob body 1 is in contact with the anti-slip texture 304 on the inner wall of the damping sleeve 302. Rotate the mounting base 201 and move it to a position where the transparent cover 202 is in the appropriate direction when opened. Fix the mounting base 201 and the damping sleeve 302 with the locking bolt 207. When opening and closing the transparent cover 202, the cooperation between the limiting insertion hole 203 and the limiting insertion post 204 can store the knob body 1 inside the transparent cover 202, which can prevent children from operating it accidentally and avoid accidents that may cause danger. When cooking, after adjusting the fire level, covering the transparent cover 202 can prevent oil stains from falling into the inside of the knob body 1 and causing difficulties in cleaning.

[0027] Example 2:

[0028] Please see the appendix Figure 1 - Appendix Figure 3 and appendix Figure 7 Furthermore, based on Embodiment 1, the auxiliary component 4 includes a rotating shaft 401 fixedly installed inside the bottom of the knob body 1. A metal sheet 402 is fixedly installed on the circumferential surface of the rotating shaft 401, and a damping rubber ring 403 is fixedly installed at the bottom of the metal sheet 402. The damping rubber ring 403 is sleeved on the circumferential surface of the rotating shaft 401. Multiple sets of springs 404 are fixedly installed between the surface of the metal sheet 402 and the inner top surface of the knob body 1. The multiple sets of springs 404 are inclined. Because the springs 404 are inclined, the compression and torsion of the springs 404 will change more complexly with the rotation angle during the rotation of the knob body 1. In the initial rotation stage, the springs 404 are inclined and have a longer effective force-bearing length, providing a relatively small damping force, making the knob body 1 easier to rotate and facilitating the user to quickly start the adjustment operation.

[0029] During the rotation of the knob body 1, due to the internal structure of the gas valve, such as the shape of the valve core and its fit with the valve body, the force exerted on the metal plate 402 is not completely uniform. This uneven force is transmitted to the spring 404. When one side is subjected to a larger force and the other side is subjected to a smaller force, the spring 404 will twist under the action of this uneven force to adapt to the force in different directions. It is necessary to use a spring 404 with appropriate stiffness to ensure that the reverse force it generates can provide an ideal damping feel, but not so strong as to cause the knob body 1 to automatically reset. The auxiliary component 4 allows the user to feel uniform and moderate resistance when rotating the knob body 1, avoiding the knob body 1 from turning too easily or too stiffly. The knob body 1 is also not easy to accidentally rotate due to external force or slight vibration. In the daily use scenario in the kitchen, it is inevitable that objects will accidentally bump into the stove knob. If the knob is turned too easily, it may cause unexpected changes in the fire level, affecting the cooking process or even causing safety hazards.

[0030] Specifically, after the knob body 1 rotates, it can form a certain friction force by adhering to the anti-slip texture 304, and the damping rubber ring 403 is sleeved on the rotating shaft 401 of the knob, using the friction of the rubber to provide a damping effect. One end of the spring 404 is fixed to the top of the knob body 1, and the other end is fixed to the metal plate 402 integrally formed with the rotating shaft 401. When the knob body 1 rotates, the metal plate 402 squeezes the spring 404, and the spring 404 generates a counterforce to provide a damping feel. Therefore, the knob body 1 is not easy to rotate accidentally due to external force or slight vibration.

[0031] The working principle of this utility model is as follows: This utility model is a switch knob for a stove. First, the stabilizing suction cup 301 is attached to the stove platform. Then, the knob body 1 is installed, and the rotating shaft 401 is connected to the corresponding connecting part of the stove. At this time, the outer surface of the knob body 1 is in contact with the anti-slip texture 304 on the inner wall of the damping sleeve 302. The mounting base 201 is rotated and adjusted to a suitable position for the opening direction of the transparent cover 202. The mounting base 201 and the damping sleeve 302 are fixed by the locking bolt 207. When the transparent cover 202 is opened and closed, the cooperation between the limiting insertion hole 203 and the limiting insertion post 204 connects the transparent cover 202 and the mounting base 201, which provides protection for the knob body 1. During cooking, the knob body... After the body 1 rotates, it can form a certain friction force by adhering to the anti-slip texture 304, and the damping rubber ring 403 is sleeved on the rotating shaft 401 of the knob, using the friction of the rubber to provide a damping effect. One end of the spring 404 is fixed to the top of the knob body 1, and the other end is fixed to the metal plate 402 integrally formed with the rotating shaft 401. When the knob body 1 rotates, the metal plate 402 squeezes the spring 404, and the spring 404 generates a counterforce to provide a damping feel. After adjusting to the appropriate firepower, the transparent cover 202 can be closed to prevent oil stains from falling into the inside of the knob body 1. When it is necessary to disassemble and clean, the locking bolt 207 is removed, and the stabilizing suction cup 301 is pulled to detach it from the stove. At this point, the entire process is complete.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
