Description

Technical Field

[0001] This application relates to the field of kettle technology, and more particularly to kettle lids with all-metal water outlets and thermos flasks. Background Technology

[0002] A thermos is a common water container in daily life, with heat preservation function, mainly used to keep hot water warm. It usually consists of a body and a lid. The lid generally includes a lid body and a push-button water valve assembly. The lid body has a water outlet that communicates with the outside. The water valve assembly includes a pressing mechanism and a valve plate, and a water outlet cavity is formed between the water outlet and the valve plate. The valve plate can move relative to the lid body under the pressure of the pressing mechanism to open or close the water outlet cavity. When the valve plate opens the water outlet cavity, the water outlet cavity connects the inner cavity of the thermos body and the water outlet, allowing water to flow out of the thermos. When the valve plate closes the water outlet cavity, the inner cavity of the thermos body and the water outlet are no longer connected, and water cannot flow out of the thermos. The inner cavity of the thermos body is sealed, which helps to keep the water warm.

[0003] Existing kettle lids are usually made of plastic, especially the lid body, which is a one-piece molded plastic part. Please refer to [link / reference]. Figure 1 These types of lids are simple and inexpensive to manufacture, but the water outlet is also made of plastic. Since the thermos usually contains hot water, this causes hot water to flow out through the plastic outlet, producing odors and even harmful substances. Currently, all-metal lids have also emerged, but they are more expensive and heavier, resulting in a less than ideal user experience. Utility Model Content

[0004] The purpose of this application is to solve the problem in the prior art where plastic kettle lids easily produce odors in the water outlet cavity, leading to a poor user experience. Therefore, this application provides a kettle lid and a thermos with an all-metal water outlet cavity. By dividing the lid body into an upper lid and a lower metal lid, and incorporating a metal tube and metal separator within the water outlet cavity, an all-metal water outlet cavity is achieved. This avoids odors caused by heat from a large area of ​​plastic, improving the user experience. Furthermore, it is low in cost, simple in structure, and easy to manufacture and assemble.

[0005] This application provides a kettle lid with an all-metal water outlet cavity, including a lid body and a water outlet valve assembly disposed in the lid body. The water outlet valve assembly includes a pressing mechanism and a valve plate. The lid body includes an upper lid body and a lower lid body connected below the upper lid body.

[0006] The upper end of the upper cover is provided with a water outlet that communicates with the outside, and the upper cover body is provided with a first water outlet cavity that communicates with the water outlet and penetrates the lower end of the upper cover body.

[0007] The lower cover is annular and connected to the lower end of the upper cover. The valve plate extends from the upper cover into the lower cover through the pressing mechanism. A second water outlet chamber is formed between the lower cover and the valve plate, which communicates with the first water outlet chamber. The valve plate can abut against or separate from the lower end of the lower cover under the action of the pressing mechanism, thereby opening and closing the second water outlet chamber.

[0008] A spacer is provided at the lower end of the upper cover facing the valve plate. The spacer is arranged circumferentially around the pressing mechanism, with one end covering the lower end face of the upper cover and avoiding the opening of the first water outlet chamber, and the other end away from the outer edge of the valve plate. This isolates the pressing mechanism in the second water outlet chamber and the lower end face of the upper cover within the spacer.

[0009] A metal pipe is installed inside the first water outlet chamber to supply water; the lower cover, the valve plate, and the isolation component are all metal parts.

[0010] By adopting the above technical solution, the lid is divided into an upper lid and a lower lid, allowing for the manufacture of the lid from different materials. In particular, the lower lid, which is closer to the valve plate, can be made of metal, and together with the metal valve plate, most of the second water outlet chamber is made of metal. At the same time, by setting a metal isolator in the second water outlet chamber, the pressing mechanism extending into the lower lid and the lower end face of the upper lid are isolated from the second water outlet chamber, making the water outlet area of ​​the second water outlet chamber entirely made of metal. Combined with the metal tube of the first water outlet chamber, this achieves an all-metal water outlet chamber, avoiding odors caused by heat in the plastic water outlet chamber during water dispensing, thus improving the user experience. Furthermore, the split lid design means that only the lower lid needs to be made of metal, and the metal tube and isolator allow for a small area of ​​metal enclosure, effectively controlling the overall weight of the lid. It also has lower cost, simple structure, and is easy to manufacture and assemble.

[0011] In some embodiments, the first water outlet cavity includes a first section and a second section connected vertically, the metal pipe includes a first pipe section that is interference-fitted with the first section and a second pipe section that is interference-fitted with the second section, and the end faces of the first pipe section and the second pipe section that meet are 45° beveled surfaces.

[0012] By adopting the above technical solution, the first pipe section and the second pipe section are assembled by splicing with a 45° bevel to form a metal pipe, which is interference-fitted with the first water outlet cavity, reducing the difficulty of manufacturing and assembly and controlling the manufacturing cost.

[0013] In some embodiments, the isolation member includes a first isolation plate and a second isolation plate that are symmetrically spliced ​​together, and the contact end faces of the first isolation plate and the second isolation plate abut against each other, and the edge end faces abut against the inner wall of the lower cover.

[0014] By adopting the above technical solution, the first and second isolation plates are spliced ​​together to form an isolation component, and the assembly is achieved by end face abutment, which reduces the difficulty of manufacturing and assembly and controls the manufacturing cost.

[0015] In some embodiments, the end of the metal tube away from the water outlet extends out of the first water outlet cavity;

[0016] The first isolation plate and the second isolation plate are symmetrically provided with a first clearance groove and a second clearance groove, respectively. After the first clearance groove and the second clearance groove are spliced ​​together, they avoid the metal pipe and are interference fit with the metal pipe.

[0017] By adopting the above technical solution, the interference fit between the metal tube and the first and second metal isolation plates improves the installation stability and reliability of the first and second isolation plates, and facilitates positioning during assembly, thus improving assembly convenience.

[0018] In some embodiments, a slot is provided on the inner side of the lower end of the upper cover, and a snap-fit ​​portion adapted to the slot is provided on the outer side of the upper end of the lower cover.

[0019] By adopting the above technical solution, the upper cover and the lower cover are assembled by snap-fit, which improves the ease of assembly.

[0020] In some embodiments, the lower end of the lower cover has a horizontal abutment surface, and the horizontal abutment surface extends vertically toward the upper cover. The outer edge of the valve plate is covered with a first sealing ring, and the horizontal abutment surface of the valve plate and the lower cover can abut against each other through the first sealing ring.

[0021] By adopting the above technical solution, the vertical extension surface extending from the horizontal contact surface is used to improve the strength of the lower end of the lower cover, thereby improving the stability and reliability of the valve plate sealing the water outlet cavity.

[0022] In some embodiments, the metal tube and the metal component are made of titanium alloy or stainless steel.

[0023] In some embodiments, a metal tea strainer is also included, which is threadedly connected to the outer periphery of the lower cover.

[0024] In some embodiments, a second sealing ring is provided at the lower end of the upper cover, and the lower end face of the second sealing ring has a groove. After the metal tea strainer is connected to the lower cover, its top end is embedded in the groove, and the deformation applies a squeezing force toward the lower cover to one side of the groove.

[0025] This application also provides a thermos, characterized in that it includes a body and a lid with an all-metal water outlet cavity as described above.

[0026] By adopting the above technical solution, the all-metal water outlet cavity of the kettle lid avoids the odor caused by the plastic water outlet cavity being heated during the water dispensing process, thus improving the user experience.

[0027] Other features and corresponding beneficial effects of this application will be described in the latter part of the specification, and it should be understood that at least some of the beneficial effects will become obvious from the description in this application.

Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0043] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a kettle lid in the prior art.

[0044] A kettle lid typically includes a lid body 1 and a push-button water outlet valve assembly. The water outlet valve assembly includes a pressing mechanism 5 and a valve plate 6. The pressing mechanism 5 typically extends through both ends of the lid body 1 and is connected to the valve plate 6 located at the lower end of the lid body 1. This allows the user to operate the pressing mechanism 5 to control the valve plate 6 to open and close the lower end of the lid body 1, thereby determining whether water can flow from the kettle lid.

[0045] The lid 1 and the pressing mechanism 5 (except for the spring) are usually made of plastic, which is low in cost and simple to manufacture. However, this also means that the space through which the water flows (i.e., the water outlet cavity 3 located in the lid 1) is made of plastic. Since thermos flasks are usually used to keep hot water warm, the hot water flows out through the plastic water outlet cavity 3, producing an odor and even harmful substances, resulting in a poor user experience.

[0046] Meanwhile, although plastic water outlets do not produce odors when cold water is poured out, they are prone to producing odors over long-term use due to the physical structure and chemical adsorption of plastic, while metals are less likely to produce odors.

[0047] Example 1:

[0048] Please see Figures 2-5 , Figure 2 This is a schematic diagram of the structure of this application; Figure 3 for Figure 2 A schematic diagram of the cross-sectional structure; Figure 4 This is a schematic diagram of the structure of the upper cover 10, lower cover 20, metal tube 30 and separator 40 after assembly in this application; Figure 5 for Figure 4 A schematic diagram of the explosion structure.

[0049] To address the aforementioned issues, this application provides a kettle lid with an all-metal water outlet cavity, comprising a lid body 1 and a water outlet valve assembly disposed within the lid body 1, the water outlet valve assembly including a pressing mechanism 5 and a valve plate 6.

[0050] The cover 1 includes an upper cover 10 and a lower cover 20 connected below the upper cover 10. The lower cover 20 is made of metal, thus dividing the previously integrally molded cover 1 into two parts. This allows the more complex upper cover 10 to still be injection molded for ease of manufacturing, while the simpler lower cover 20 is made of metal and can be machined or used in other metal forming processes. This method controls the overall manufacturing cost and weight of the cover 1, and also allows the sidewall of the water outlet cavity 3 (i.e., the second water outlet cavity 21 in this embodiment) at the lower end of the cover 1 to be made of metal.

[0051] The upper end of the cover 10 is provided with a water outlet 2 that communicates with the outside, and the upper cover 10 is provided with a first water outlet cavity 11 that communicates with the water outlet 2 and extends through the lower end of the upper cover 10. Furthermore, a metal pipe 30 is provided in the first water outlet cavity 11 to supply water, thereby realizing that the water outlet cavity 3 inside the cover 1 is formed by being surrounded by metal material.

[0052] The lower cover 20 is annular and connected to the lower end of the upper cover 10. The valve plate 6 extends from the upper cover 10 into the lower cover 20 through the pressing mechanism 5. A second water outlet chamber 21 is formed between the lower cover 20 and the valve plate 6, which communicates with the first water outlet chamber 11. That is, the first water outlet chamber 11 and the second water outlet chamber 21 constitute the water outlet chamber 3 in the existing kettle lid. The valve plate 6 can abut or separate from the lower end of the lower cover 20 under the action of the pressing mechanism 5, thereby opening and closing the second water outlet chamber 21. Furthermore, the valve plate 6 is a metal part, so that the bottom surface of the second water outlet chamber 21 is made of metal.

[0053] At this point, the main body of the water outlet chamber 3 is made of metal. However, since the top surface of the second water outlet chamber 21 is the lower end surface of the upper cover 10, and the inlet of the first water outlet chamber 11 is located on the lower end surface of the upper cover 10, hot water easily comes into contact with the lower end surface of the upper cover 10, which is made of plastic, during the pouring process, thus producing an odor. At the same time, the main part of the pressing mechanism 5 is also made of plastic. The pressing mechanism 5 extends into the second water outlet chamber 21 to connect with the valve plate 6. Although the hot water usually does not come into contact with the pressing mechanism 5 located in the middle during the pouring process, it is easily heated and produces an odor due to direct exposure to heat.

[0054] Therefore, a metal isolator 40 is provided at the lower end of the upper cover 10 facing the valve plate 6. The isolator 40 is arranged around the circumference of the pressing mechanism 5, that is, around the pressing mechanism 5 that extends into the second water outlet chamber 21. One end of the isolator 40 covers the lower end face of the upper cover 10 and avoids the opening of the first water outlet chamber 11, while the other end is away from the outer edge of the valve plate 6, that is, away from the abutment between the valve plate 6 and the lower cover 20, which is the water outlet. This isolates the pressing mechanism 5 in the second water outlet chamber 21 and the lower end face of the upper cover 10 inside the isolator 40, realizing an all-metal water outlet chamber 3, thereby preventing the plastic parts from contacting hot water or directly contacting hot air during the water pouring process, which would produce odors.

[0055] It should be noted that one end of the isolation member 40 covers the lower end face of the upper cover 10, meaning that the isolation member 40 can be covering the lower end face of the upper cover 10, fitting the lower end face of the upper cover 10, or other structures, as long as it can isolate the lower end face of the upper cover 10.

[0056] The other end of the isolator 40 extends toward the valve plate 6 and is away from the outer edge of the valve plate 6. This means that the isolator 40 surrounds the pressing mechanism 5 in the second water outlet chamber 21 in a ring shape, and is far away from the water outlet, thereby reducing the direct impact of hot air on the pressing mechanism 5 and avoiding affecting the water outlet. At the same time, it can be understood that this end of the isolator 40 can be as close as possible to the surface of the valve plate 6 to improve the isolation effect, but a certain gap still needs to be set between the two to avoid collision interference caused by processing errors during assembly.

[0057] This method not only achieves an all-metal water outlet chamber 3, avoiding odors caused by heat in the plastic water outlet chamber 3 during water dispensing, thus improving the user experience, but also, the split lid 1 means that only the lower lid 20 needs to be made of metal. Furthermore, the metal tube 30 and the separator 40 allow for a small area of ​​metal enclosure, effectively controlling the overall weight of the lid. This design is also cost-effective, simple in structure, and easy to manufacture and assemble.

[0058] It should also be noted that although the lid of this kettle adopts a split lid body 1, the assembly method of the lid body 1 and the water outlet valve assembly and the water outlet principle have not changed. Therefore, this kettle lid can use existing water outlet valve assemblies, that is, it can use existing pressing mechanism 5 and connection method with valve plate 6, such as the opening mechanism in CN118592813A, the pressing assembly and inner sealing assembly in CN216823017U, the valve assembly and transmission assembly in CN222018180U, etc.

[0059] Furthermore, the assembly of the pressing mechanism 5 and the valve plate 6 can be either a connection between the pressing mechanism 5 and the upper surface of the valve plate 6, eliminating the need for a through hole in the valve plate 6, thus simplifying the structure and improving the sealing performance of the valve plate 6; or a through hole can be provided in the middle of the valve plate 6, with the end of the pressing mechanism 5 passing through the through hole and connecting to the lower surface of the valve plate 5, thereby making the installation of the valve plate 6 more reliable. Both methods are acceptable, and the choice can be made according to the requirements.

[0060] In one specific embodiment, the valve plate 6 of the kettle lid is assembled with the pressing mechanism 5 through a through hole, which facilitates the assembly of two different materials (metal valve plate 6 and plastic pressing mechanism 5) and ensures the reliability of valve plate 6 installation, thereby improving the reliability of kettle lid opening and closing. A sealing ring can be set at the through hole to ensure sealing.

[0061] Furthermore, the lid of this kettle also includes a thermometer, which can replace the transmission rod in the pressing mechanism 5 with a mechanical thermometer, thereby realizing the measurement of the water temperature inside the kettle. Its structure is, for example, CN221635500U, a stainless steel thermos cup switch assembly with a mechanical thermometer.

[0062] In one embodiment, the first water outlet cavity 11 includes a first section and a second section connected vertically. The metal pipe 30 includes a first pipe section 31 that is interference-fitted with the first section and a second pipe section 32 that is interference-fitted with the second section. The end faces of the first pipe section 31 and the second pipe section 32 are 45° beveled. That is, the first pipe section 31 and the second pipe section 32 are spliced ​​and assembled by the 45° beveled to form the metal pipe 30, which is interference-fitted with the first water outlet cavity 11. This reduces the difficulty of manufacturing and assembly and controls the manufacturing cost.

[0063] In one embodiment, the isolation component 40 includes a first isolation plate 41 and a second isolation plate 42 that are symmetrically spliced ​​together, with the contact end faces of the first isolation plate 41 and the second isolation plate 42 abutting against each other, and the edge end faces abutting against the inner wall of the lower cover 20. That is, the isolation component 40 is formed by splicing and assembling the first isolation plate 41 and the second isolation plate 42, and the assembly is achieved by the end faces abutting against each other, which reduces the difficulty of manufacturing and assembly and controls the manufacturing cost.

[0064] In one embodiment, the end of the metal tube 30 away from the outlet 2 extends out of the first outlet chamber 11.

[0065] The first isolation plate 41 and the second isolation plate 42 are symmetrically provided with a first clearance groove 43 and a second clearance groove 44. After the first clearance groove 43 and the second clearance groove 44 are spliced ​​together, they avoid the metal pipe 30 and are interference fit with the metal pipe 30, thereby improving the installation stability and reliability of the first isolation plate 41 and the second isolation plate 42, and facilitating the positioning of the installation position by the metal pipe 30 and the clearance groove during assembly. In particular, the upper cover 10 and the isolation component 40 usually need to be provided with corresponding vent holes 4, which improves the ease of assembly through positioning.

[0066] In one embodiment, a slot 12 is provided on the inner side of the lower end of the upper cover 10, and a snap-fit ​​part 22 adapted to the slot 12 is provided on the outer side of the upper end of the lower cover 20. That is, the upper cover 10 and the lower cover 20 are assembled by snap-fit, which improves the ease of assembly.

[0067] In one embodiment, the lower end of the lower cover 20 has a horizontal abutment surface 23, and the horizontal abutment surface 23 extends vertically toward the upper cover 10 with a curved extension surface 24, which can improve the strength of the lower end of the lower cover 20, thereby improving the stability and reliability of the valve plate 6 abutting against the lower end of the lower cover 20, and further improving the stability and reliability of the valve plate 6 sealing the water outlet cavity 3.

[0068] Preferably, the outer edge of the valve plate 6 is covered with a first sealing ring 61, and the horizontal contact surface 23 of the valve plate 6 and the lower cover 20 can be contacted by the first sealing ring 61, thereby further improving the sealing effect.

[0069] In one embodiment, the metal tube 30 and the metal parts are made of titanium alloy or stainless steel, such as 304 or 316 stainless steel.

[0070] Please see again Figure 1 In one embodiment, the lid also includes a metal tea strainer 7, which facilitates tea brewing for the user. Preferably, the metal tea strainer 7 is threaded to the outer periphery of the lower lid 20, making it easy for the user to assemble and disassemble.

[0071] Please see Figure 6 , Figure 6 This is a partial structural diagram of this application.

[0072] In one embodiment, a second sealing ring 13 is provided at the lower end of the upper cover 10. The sealing ring is positioned similarly to the sealing ring in the existing cover 1, and both are used to seal the gap between the lid and the body.

[0073] In this embodiment, the lower end face of the second sealing ring 13 has a groove 14. After the metal tea strainer 7 is connected to the lower cover 20, its top end is embedded in the groove 14, and the deformation applies a pressing force towards the lower cover 20 to one side of the groove 14, thereby relatively improving the stability and reliability of the connection between the metal tea strainer 7 and the lower cover 20. Furthermore, by isolating the upper cover 10 and the metal tea strainer 7 through the sealing ring, plastic microparticle contamination caused by the frequent disassembly and assembly of the metal tea strainer 7 against the upper cover 10 during long-term use can be avoided, thus improving safety.

[0074] Preferably, the metal tea strainer 7 includes a tea container and a filter element, thereby preventing tea leaves from entering the lid 1. Specifically, the filter element is located between the lower lid 20 and the tea container, with one end threaded to the lower lid 20 and the other end threaded to the tea container, making it easy to disassemble and assemble, and convenient for users.

[0075] Example 2:

[0076] Based on Embodiment 1, this application embodiment also provides a thermos, including a body and a lid with an all-metal water outlet cavity 3 as in Embodiment 1. The all-metal water outlet cavity 3 of the lid avoids odors caused by the plastic water outlet cavity 3 being heated during the water dispensing process, thus improving the user experience.

[0077] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
