Description

Technical Field

[0001] This utility model belongs to the field of pot handle processing technology, specifically a heat-resistant composite handle. Background Technology

[0002] In daily life, 2-in-1 products are favored for their multi-functionality, with 2-in-1 clip-on all-metal handles being particularly popular. However, existing 2-in-1 clip-on all-metal handles have certain limitations in use. Because of the excellent thermal conductivity of all-metal materials, to prevent burns during use, the handle is typically designed with a staggered structure. However, this staggered design introduces a new problem: the contact between the handle and the hand is not natural or comfortable enough, resulting in a feeling of distance and significantly impacting the user experience. This leads to a poor overall feel and fails to meet consumers' demands for a high-quality, comfortable user experience. Utility Model Content

[0003] To address the problems mentioned in the background section, this utility model provides a heat-resistant composite handle.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a heat-conducting composite handle, comprising a heat-conducting component, wherein an upper cover plate and a lower cover plate are respectively provided on the upper and lower sides of the heat-conducting component, the upper cover plate, the heat-conducting component, and the lower cover plate are fixedly connected and stacked; the front end of the heat-conducting component extends between the upper cover plate and the lower cover plate for connection with the pot body; when the upper cover plate and the lower cover plate are fixedly connected to the heat-conducting component, the upper cover plate and the lower cover plate form installation gaps on the left and right sides and the rear end of the heat-conducting component, and an interlayer ring with an opening is fixedly installed in the installation gap, wherein the side of the heat-conducting component near the front end is located at the opening of the interlayer ring and a gap is left between the heat-conducting component and the interlayer ring.

[0005] In a further technical solution, the inner surface of the sandwich ring does not contact the heat-conducting component.

[0006] In a further technical solution, the upper cover plate is provided with an upper flange with a front opening, and the lower cover plate is provided with a lower flange with a front opening; when the upper cover plate, the heat-conducting component, and the lower cover plate are fixedly connected, the heat-conducting component is located inside the upper flange and the lower flange, and the inner side of the interlayer ring is in contact with the outer side of the upper flange and the lower flange.

[0007] In a further technical solution, a hanging ring is provided at the rear end of the interlayer ring.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] 1. Improved thermal insulation performance

[0010] The heat-conducting component has upper and lower cover plates on both sides, which are fixedly connected to form a stacked structure. An open-ended interlayer ring is installed within the installation gap, with the front end of the heat-conducting component located at the opening of the interlayer ring and leaving a gap between it and the ring. This design effectively forms a heat insulation barrier, preventing heat generated by the pot body from being conducted to the handle, thus significantly reducing the handle's temperature and avoiding the risk of burns to consumers during use. It solves the problem of burns easily caused by existing two-in-one pots with a full metal handle in the middle.

[0011] 2. User experience optimization

[0012] Compared to traditional misaligned handles, this technical solution, through a reasonable structural layout, including the clever coordination of components such as the upper cover plate, lower cover plate, and interlayer ring, makes the grip of the entire handle more ergonomic. The contact between the hand and the handle is more natural and comfortable, greatly reducing the feeling of being separated from the hand, improving the comfort of consumers during use, enhancing the user experience, and meeting consumers' demand for a high-quality and comfortable user experience.

[0013] 3. Enhanced structural stability

[0014] The fixed connection and stacking of the upper cover plate, heat-conducting components, and lower cover plate, along with the fixed installation of the interlayer ring within the installation gap, make the entire handle structure more stable. The tight fit between the components enhances the overall rigidity and deformation resistance of the handle, thereby improving its durability and reliability during long-term use, extending the product's lifespan, and avoiding problems such as the handle becoming loose or deformed, which could affect the performance.

[0015] 4. Improved safety

[0016] Through reasonable heat insulation design and sturdy structure, it not only prevents scalding accidents during normal use, but also effectively blocks the transfer of heat to the handle when the pot body is heated unevenly or the temperature rises sharply in a short period of time, further improving the safety performance of the product and providing consumers with more reliable use protection.

[0025] 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.

[0026] like Figure 1-8 As shown, this embodiment proposes a heat-conducting composite handle, including a heat-conducting component 1. The heat-conducting component 1 has an upper cover plate 2 and a lower cover plate 3 on its upper and lower sides, respectively. The upper cover plate 2, the heat-conducting component 1, and the lower cover plate 3 are fixedly connected and stacked. The front end of the heat-conducting component 1 extends between the upper cover plate 2 and the lower cover plate 3 for connection with the pot body. When the upper cover plate 2 and the lower cover plate 3 are fixedly connected to the heat-conducting component 1, the upper cover plate 2 and the lower cover plate 3 form installation gaps 23 on the left and right sides and the rear end of the heat-conducting component 1. A sandwich ring 4 with an opening is fixedly installed within the installation gap 23. The side of the heat-conducting component 1 closest to its front end is located at the opening of the sandwich ring 4, with a gap between it and the sandwich ring 4. The inner surface of the sandwich ring 4 does not contact the heat-conducting component 1. When the upper cover plate 2, the heat-conducting component 1, and the lower cover plate 3 are fixedly connected, the sandwich ring 4 is tightly fixed between the upper cover plate 2 and the lower cover plate 3.

[0027] In this embodiment, an upper cover plate 2 and a lower cover plate 3 are arranged on the upper and lower sides of the heat-conducting component 1, and the three are fixedly connected to form a stacked structure. An interlayer ring 4 with an opening is installed in the installation gap 23, and the front end of the heat-conducting component 1 is located at the opening of the interlayer ring 4, leaving a gap between it and the interlayer ring 4. This design effectively forms a heat insulation barrier, preventing the heat generated by the pot body from being conducted to the handle, thereby significantly reducing the temperature of the handle and avoiding the risk of burns to consumers during use. This solves the problem of burns easily caused by existing two-in-one all-metal handles with a middle clamp. In addition, compared with the traditional staggered structure handle, this technical solution, through a reasonable structural layout, including the clever cooperation of components such as the upper cover plate 2, the lower cover plate 3, and the interlayer ring 4, makes the grip of the entire handle more ergonomic, the contact between the hand and the handle more natural and comfortable, greatly reducing the feeling of being separated from the hand, improving the comfort of consumers during use, improving the user experience, and meeting consumers' needs for a high-quality and comfortable user experience.

[0028] The upper cover plate 2 has an upper flange 201 with an opening at the front end, and the lower cover plate 3 has a lower flange 301 with an opening at the front end. When the upper cover plate 2, the heat-conducting component 1, and the lower cover plate 3 are fixedly connected, the heat-conducting component 1 is located inside the upper flange 201 and the lower flange 301, and the inner side of the interlayer ring 4 contacts the outer side of the upper flange 201 and the lower flange 301. In this embodiment, the upper flange 201 and the lower flange 301 are used to limit the heat-conducting component 1 and the interlayer ring 4, thereby enhancing the structural stability of the handle. The rear end of the interlayer ring 4 is provided with a hanging ring 401, which allows the pot to be easily suspended by the handle.

[0029] In this embodiment, two metal pillars can be cast on the heat-conducting component 1, and the upper cover plate 2 and the lower cover plate 3 are riveted together. The two metal pillars on the heat-conducting component 1 expand and deform through the holes in the upper cover plate 2 and the lower cover plate 3, and then connect together. In addition, the thickness of the heat-conducting component 1 is controlled to be less than the thickness of the sandwich ring 4, so that the upper cover plate 2 and the lower cover plate 3 are isolated from the upper and lower sides of the heat-conducting component 1 when connected.

[0030] In addition to the connection methods mentioned above, the upper cover plate 2, the lower cover plate 3, and the heat-conducting component 1 can also be assembled together by means of screws, rivets, snap fasteners, or other structures.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances. Content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
