Description

Technical Field

[0001] The utility model belongs to the technical field of kettle knob devices, and in particular relates to a heat-insulating kettle knob device. Background Art

[0002] As an important part of the kettle, the design and function of the kettle knob device directly affect the user experience, the safety performance of the kettle and the heat preservation effect. The traditional kettle knob device usually includes a kettle lid and a kettle knob fixed or movably connected to the kettle lid. Its core function is to seal the mouth of the kettle to prevent the liquid in the kettle from overflowing, and provide an operating component that is easy to hold and rotate so that the user can open or close the mouth of the kettle to pour water, add water or clean. The early kettle knob design was relatively simple, often a fixed knob or handle. The user needed to lift the kettle knob completely to open the mouth of the kettle, which met the basic usage needs to a certain extent. However, with the improvement of quality of life and the diversification of user needs, traditional kettle knob devices have gradually exposed some disadvantages:

[0003] Risk of scalding: When pouring water or adding ingredients, the user's fingers need to directly touch the kettle knob, and the kettle knob is only separated from the hot liquid inside the kettle by a layer of kettle lid, which can easily cause heat to be quickly transferred to the kettle knob, causing the user to accidentally get scalded. Especially when pouring water quickly or the temperature of the liquid in the kettle is extremely high, the risk of scalding increases significantly. Operation force and skill requirements: Traditional kettle knobs require a large opening force, which may be difficult to operate, especially for the elderly, children or users with weak hand strength. In addition, lifting the kettle knob completely may cause the kettle body to tilt too much, and the liquid may splash out or the pouring speed may be difficult to control. Heat loss: As part of the kettle lid, the kettle knob has a large contact area with the kettle body. Traditional designs often lack effective insulation measures, resulting in rapid dissipation of heat in the kettle through the kettle knob, affecting the thermal insulation performance of the kettle. Single function and appearance: Traditional kettle knob devices usually only have basic opening and closing functions, tend to be single in design, lack interesting elements for interaction with users, and cannot meet the needs of modern consumers for personalization and fun in life.

[0009] The design of the threaded locking bracket provides a stable and reliable way to fix the kettle knob, ensuring that the kettle knob can remain in the precise position after long-term use and multiple rotations, avoiding the normal use of the kettle due to looseness. At the same time, the threaded connection is easy to disassemble and maintain, which improves the maintainability and service life of the product.

[0010] On the basis of the above technical solution, the heat-insulating kettle knob device of the utility model can also be improved as follows:

[0011] Wherein, the connecting piece is specifically a protrusion arranged at the bottom of the locking lower bolt, and a slot is arranged on the top of the pot cover, and the slot matches the protrusion.

[0012] Furthermore, the internal thread is located above the inner side of the locking lower bolt, and the length of the internal thread is 1 / 2 of the length of the locking lower bolt.

[0013] Furthermore, a groove is provided on the outer side of the locking lower bolt, the groove corresponds to the upper 1 / 2 of the internal thread, and the groove is not in direct contact with the main body.

[0014] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the setting of the positioning groove and the fixed bearing ensures the precise guidance and smooth rotation of the kettle knob during rotation, reduces friction resistance, and prolongs the service life of the components. At the same time, the precise structural design ensures that the kettle knob can stably stay in the preset position after rotation, which is convenient for users to identify and control the opening and closing state of the kettle mouth, further improving the convenience of use and user experience.

[0015] Furthermore, the main body includes an arc-shaped part and a clamping part, the arc-shaped part is located above the clamping part, the length of the arc-shaped part is equal to the sum of the length of the upper part of the locking bolt and the length of the groove, and the length of the clamping part is equal to the length of the locking lower bolt minus the groove and the connecting part.

[0016] Furthermore, the main body wraps the upper locking bolt and the lower locking bolt, and the length of the main body is equal to the sum of the lengths of the upper locking bolt and the lower locking bolt.

[0017] Furthermore, a supporting plate is provided at the bottom of the pot cover, and the supporting plate is used to fix the pot knob device.

[0018] The beneficial effects of adopting the above-mentioned improvement scheme are as follows: the setting of the support plate enhances the mechanical connection strength between the kettle knob and the kettle lid, prevents the kettle knob from loosening or deforming due to uneven force or long-term use, and ensures the long-term stability and reliability of the product. In addition, the support plate fixing method may simplify the assembly process of the kettle knob and the kettle lid, which is conducive to the standardization and efficiency improvement of production and manufacturing.

[0019] Furthermore, the arc-shaped member is semicircular, and the diameter of the semicircle is equal to the sum of the length of the upper part of the locking bolt and the length of the groove.

[0020] Furthermore, the size of the support plate is equal to the size of the interior of the pot cover.

[0021] Furthermore, the main body material includes one of heat reflective material, porous material, non-metallic heat insulating material and vacuum material.

[0022] Compared with the prior art, the heat-insulating kettle knob device provided by the utility model has the following beneficial effects:

[0023] Highly efficient thermal insulation, reducing the risk of scalding:

[0024] 1. The kettle knob of the utility model adopts a rotating structure design. Users do not need to lift the kettle knob completely, but only need to gently rotate it to adjust the size of the kettle mouth, which greatly reduces the chance of fingers directly contacting the high-temperature kettle knob and significantly reduces the risk of scalding. At the same time, the inside of the kettle knob and the contact part with the kettle lid may use heat-insulating materials or structural designs to effectively isolate the high temperature inside the kettle, further ensuring the safety of users;

[0025] 2. Easy operation and improved user experience:

[0026] The rotating kettle knob structure allows users to easily and accurately control the opening and closing of the kettle mouth without excessive operating force, which is suitable for users of different ages and physical conditions.

[0047] Furthermore, in the above technical solution, the material of the main body 5 includes one of heat reflective material, porous material, non-metallic heat insulating material and vacuum material.

[0048] Heat Reflective Materials:

[0049] Metal materials: such as gold, silver, nickel, aluminum and its alloys (such as aluminum alloy), and metal-plated polyester, etc. These materials have high reflectivity and can reflect most of the thermal radiation back, thereby reducing the transfer of heat by radiation.

[0050] Metal composite materials: such as aluminum film foam, aluminum foil insulation materials, etc., which combine the reflective properties of metals with the thermal insulation properties of other materials to form composite insulation products.

[0051] Porous Materials:

[0052] Foam materials: such as polystyrene foam (EPS), polyurethane foam (PU), phenolic foam (PF), etc. They contain a large number of closed or interconnected pores filled with air or inert gas. Due to the low thermal conductivity of the gas, it can effectively slow down heat conduction.

[0053] Fiber materials: such as rock wool, glass wool, ceramic fiber, asbestos (gradually eliminated), mineral wool, etc., are composed of a large number of fine fibers interwoven. The air layer between the fibers constitutes a thermal insulation barrier. At the same time, the fiber material itself also has low thermal conductivity.

[0054] Vacuum materials:

[0055] Vacuum insulation panel / vacuum insulation layer: By forming a vacuum cavity between two thin plates, the convection heat transfer path is eliminated and the heat conduction efficiency is significantly reduced. This material has high process requirements and is often used in high-end home appliances (such as refrigerators, water heaters) and aerospace and other occasions that require efficient insulation.

[0056] Non-metallic insulation materials:

[0057] Ceramics: such as high-temperature ceramic fiber insulation felt, which is made of hollow alumina balls and has excellent high-temperature thermal insulation performance, low thermal conductivity and sound absorption performance. It is suitable for applications such as manufacturing and medical equipment that require high-temperature resistance.

[0058] Polymers: such as polystyrene boards (EPS boards, XPS boards), polyurethane foam materials, etc. They are both porous materials and synthetic polymer materials. They have good thermal insulation properties and construction convenience, and are often used for building exterior wall insulation.

[0059] Composite insulation materials: such as ventilation composite insulation materials, fireproof composite insulation materials, etc., are usually made of a variety of materials with different properties through a special process. They aim to combine the advantages of each component to provide comprehensive insulation, fire protection, moisture-proof and other functions.

[0060] like Figure 1 , Figure 2 As shown, it is a second embodiment of a heat-insulating kettle knob device provided by the utility model. In this embodiment, it includes the following parts:

[0061] Pot lid: As the top closing element of the pot, the pot lid is sealed and fixed to the pot body through conventional buckles, threads or other suitable connection methods;

[0062] Insulation rotating main body material: It is set in the center of the kettle lid and serves as the main load-bearing and insulation component of the kettle knob. The main body material is made of materials with good thermal insulation properties (such as ceramics, silicone, polymer composite materials, etc.), and there may be an air insulation layer or a reflective insulation coating inside or in contact with the kettle lid to further enhance the insulation effect;

[0063] The toggle structure body: connected to the heat-insulating rotating main body material, forming the rotating operation part of the kettle knob. The toggle structure body can rotate freely around the central axis of the heat-insulating material, and cooperates with the opening / closing mechanism of the kettle lid through the internal mechanical structure (such as gears, cams, ratchets, etc.) to realize the opening and closing action of the kettle lid;

[0064] Locking upper and lower bolts: located inside or on the edge of the lid, they serve as a locking device to control the opening and closing state of the lid. When the main body of the toggle structure rotates around the insulation material, the lid is unlocked and locked by cooperating with the locking upper and lower bolts;

[0065] Operation process:

[0066] When boiling water to make tea, the specific operation of the kettle knob of the utility model is as follows:

[0067] Open the lid:

[0068] Apply upward force: The user holds the toggle structure body and applies an upward pulling force. At this time, the heat-insulating rotating main body material rises together with the toggle structure body, but due to its good heat-insulating performance, the user's hand will not feel obvious heat.

[0069] Rotate to open: While maintaining the upward force, the user moves the main structure around the insulation material to rotate the upper and lower bolts. During the rotation, the mechanical structure inside the main structure interacts with the upper and lower bolts, causing the upper bolt to move upward and disengage from the locked position of the lid, while the lower bolt moves downward to release the restraining force on the lid.

[0070] Opening the lid: As the upper and lower bolts are unlocked, the lid automatically opens to a certain angle under its own gravity or the action of an auxiliary spring. The user can continue to rotate the main body of the structure as needed to further increase the lid opening in order to pour water or add tea leaves.

[0071] To close the lid:

[0072] Apply downward force: the user rotates the dial structure body in the opposite direction to move it downward while maintaining the rotational force on the closing direction of the pot lid.

[0073] Rotation to close and lock: During the rotation process, the mechanical structure in the main body of the structure is toggled to drive the upper and lower bolts to return to their original positions. The upper bolt moves downward and re-embeds into the locking position of the lid, and the lower bolt moves upward to exert a restraining force on the lid to ensure that the lid is tightly closed.

[0074] The lid is fully closed: When rotated into place, the lid is completely locked, forming a seal to prevent heat loss and liquid spillage.

[0075] Specifically, the principle of the utility model is:

[0076] 1. The structural principle of the rotating kettle knob:

[0077] The kettle knob of the utility model realizes the rotation function through the internal positioning groove and fixed bearing. The positioning groove ensures that the kettle knob moves along the preset track during the rotation process to prevent deviation; the fixed bearing reduces the rotation resistance and ensures the smoothness of rotation. The kettle knob and the kettle lid are connected by a movable kit, allowing the kettle knob to rotate freely relative to the kettle lid while maintaining a firm connection between the two to prevent the kettle knob from loosening or falling off during use;

[0078] 2. Thermal insulation principle:

[0079] The thermal insulation effect may be achieved based on the following technical means:

[0080] Material selection: Use insulating materials with low thermal conductivity to make the inside of the kettle knob or the part in contact with the kettle lid, such as ceramics, silicone, polymer composite materials, etc. These materials can effectively prevent heat from being transferred through the kettle knob;

[0081] Air insulation: An air layer is designed inside the kettle knob or at the contact point with the kettle lid to form a natural insulation barrier using the low thermal conductivity of air;

[0082] Reflective insulation: If the kettle knob is made of metal, the surface can be coated with a high reflectivity coating to reflect the heat radiation inside the kettle back into the kettle, reducing the heat transfer to the outside;

[0083] 3. Interesting spinning fidget spinner principle:

[0084] The design of the rotating fidget spinner-style kettle knob draws on the principle of the fidget spinner. By optimizing the weight distribution and shape of the kettle knob, it can keep spinning for a long time even when subjected to a small external force. When the user rotates the kettle knob, they can feel continuous and stable rotation feedback, just like operating a fidget spinner, which increases the fun and playability of the product.
