Abstract
Description
Technical Field
[0001] This application relates to the field of thermos cup technology, and more particularly to a heat-insulating double-walled silver cup. Background Technology
[0002] With the development of the times, people are paying increasing attention to their health. Water, as an essential substance for the human body, plays a vital role in health due to its quality. In daily life, water is usually stored in cups, but traditional cups are mostly made of stainless steel or glass and do not have water purification or antibacterial functions. Silver ions, however, have good antibacterial properties, capable of disrupting bacterial cell membranes and interfering with their metabolic functions, thereby inhibiting microbial reproduction. In addition, silver's antioxidant properties can slow down the oxidative decomposition of organic matter in water, reducing odor.
[0003] However, due to silver's excellent thermal conductivity, using a silver cup to hold hot water will cause the surface temperature to rise rapidly, posing a risk of scalding the user. Furthermore, because silver is relatively soft, it's impossible to achieve proper insulation by creating a vacuum when making a double-walled silver cup. Currently, most silver cups are used to hold lukewarm water, which has certain limitations. Therefore, there is an urgent need for a heat-insulating double-walled silver cup that can prevent scalding. Utility Model Content
[0004] One of the objectives of this application is to provide a heat-insulating double-layer silver cup that can solve at least one of the defects in the above-mentioned background art.
[0005] To achieve at least one of the above objectives, the technical solution adopted in this application is as follows: a heat-insulating double-layer silver cup, comprising an inner liner and an outer shell, both the inner liner and the outer shell being made of metallic silver, the outer shell being provided with a receiving cavity and a connecting part, the upper end of the inner liner being folded downward to form a pressing part, the pressing part being provided with a side ear, the inner liner at least partially extending into the receiving cavity; the side ear cooperating with the connecting part to fix the outer shell and the inner liner together, forming a sealed environment within the receiving cavity; the receiving cavity is filled with a heat-insulating layer.
[0006] By replacing traditional stainless steel or glass cups with pure silver cups, the properties of silver ions can be used to disinfect and purify the water inside. The insulation layer inside the cavity is fitted to the outer wall of the inner liner; when the temperature of the inner liner rises, the insulation layer effectively reduces heat transfer, providing anti-scalding and heat insulation effects.
[0007] Preferably, a heat dissipation assembly is provided between the outer shell and the inner liner. The heat dissipation assembly includes a cup lug, an annular protrusion on the inner side of the cup lug, and an annular groove on the connecting portion for mounting the annular protrusion. The side lug fits against the upper end face of the annular protrusion, and the diameter of the side lug is larger than the diameter of the annular protrusion. With this configuration, the cup lug contacts both the outer shell and the inner liner simultaneously. When heat is transferred from the inner liner, the cup lug can absorb heat from both the inner liner and the outer shell to prevent the outer shell from overheating. Furthermore, the side lug and the annular groove, when engaged, can limit the position of the cup lug, further improving the installation stability of the cup lug.
[0008] Preferably, the cup handle is made of a heat-dissipating material such as zinc alloy. This design further enhances the heat dissipation effect of the cup handle by using a material with excellent heat dissipation properties, such as zinc alloy.
[0009] Preferably, the cup also includes a lid, with the top of the inner liner protruding from the cup handle, the lid extending into the cup handle, and the diameter of the lid being larger than the diameter of the pressing part. With this configuration, embedding the lid into the cup handle provides insulation and sealing for the water in the inner liner; removing the lid allows it to be used as a cup, with water from the inner liner poured directly into the lid for drinking.
[0010] Preferably, a mutually cooperating limiting structure is provided between the outer wall of the pressing part and the inner wall of the cup lid. This configuration allows the cup lid to be fixedly installed on the pressing part via the limiting structure, preventing the cup lid from falling off when the double-layered silver cup is carried.
[0011] Preferably, the limiting structure is a limiting block, with a portion of the wall of the pressing part recessed inward to form a limiting groove. The limiting block is fixedly installed within the limiting groove, and the thickness of the limiting block is greater than the depth of the limiting groove. The mating surfaces of the limiting block and the cup lid are provided with mutually engaging threads. With this configuration, when the cup lid is closed, rotating the lid seals the water in the inner liner through the mutually engaging threaded structure, preventing hot water from spilling out and scalding the user.
[0012] Preferably, the insulation layer is expanded polystyrene foam. This design allows the expanded polystyrene foam to trap the heat transmitted from the inner liner, reducing heat conduction to the outer shell through the air. In addition, the expanded polystyrene foam also serves to absorb shock and limit movement, preventing the inner liner from shifting.
[0013] Preferably, the side lugs and the connecting portion are fixedly connected by adhesive or welding. This configuration allows the inner liner and outer shell to be integrated into a single structure through the fixed connection of the side lugs and the connecting portion.
[0014] Preferably, the pressing part forms a downward-opening mounting groove with the side wall of the inner liner, and the top end of the connecting part is folded upward to form an insert, which extends into the mounting groove. This arrangement increases the adhesion area between the connecting part and the inner liner, thereby improving the installation stability of the inner liner and the outer shell. In addition, some of the heat from the inner liner and the outer shell can be transferred to the insert, and the insert will not come into direct contact with the user's hand, thus further reducing the heat on the parts of the outer shell that come into direct contact with the user.
[0015] Preferably, a rubber pad is installed at the bottom of the mounting groove, and the rubber pad has a slot for inserting the plug. With this arrangement, when heat is transferred from the inner liner to the outer shell, some of the heat is transferred to the rubber pad, thus reducing the heat transfer from the inner liner to the outer shell. Additionally, the slot on the rubber pad can be used to position the plug; when the plug is inserted into the slot, it is at the correct installation point.
[0016] Compared with the prior art, the beneficial effects of this application are as follows:
[0017] Both the inner liner and the outer shell are made of pure silver. The properties of silver ions not only disinfect and purify the water inside the cup, but also slow down the oxidation and decomposition of organic matter in the water, reducing odors and further improving the quality of drinking water. In addition, a heat dissipation component is installed at the connection point between the inner liner and the outer shell. When heat from the inner liner is conducted to the outer shell through this connection point, the heat dissipation component absorbs some of the heat, further improving the anti-scalding effect of the double-walled silver cup.
[0018] The insulation layer filling the cavity can fit snugly against the outer wall of the inner liner. When the temperature of the inner liner rises, the insulation layer reduces heat transfer, thus providing anti-scalding and heat insulation effects. In addition, the insulation layer also acts as a shock absorber and positioning element, preventing the inner liner from shifting. This invention has the advantages of simple structure, good heat insulation, and high safety. Attached Figure Description

[0027] The present application will be further described below with reference to specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.
[0028] In the description of this application, it should be noted that the terms "center", "lateral", "longitudinal", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., which indicate the orientation and positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and should not be construed as limiting the specific protection scope of this application.
[0029] It should be noted that the terms "first," "second," etc., in the specification and claims of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.
[0030] The terms “comprising” and “having”, and any variations thereof, in the specification and claims of this application are intended to cover non-exclusive inclusion, for example, a process, method, system, product, or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or device.
[0031] One aspect of this application provides a heat-insulating double-layer silver cup, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, one preferred embodiment includes an inner liner 1 and an outer shell 2, both made of metallic silver. The outer shell 2 has a receiving cavity 21 and a connecting portion 22. The upper end of the inner liner 1 is folded downward to form a pressing portion 11, and a side lug 110 is provided on the pressing portion 11. The inner liner 1 extends at least partially into the receiving cavity 21. After the side lug 110 fits against the connecting portion 22, the outer shell 2 and the inner liner 1 are fixedly connected, thereby forming a sealed environment within the receiving cavity 21. In addition, the inner liner 1 and the outer shell 2 only connect at the contact point of the side lug 110 and the connecting portion 22, and the other parts are separated by the receiving cavity 21.
[0032] Specifically, such as Figure 2 As shown, the side ear 110 and the connecting part 22 are fixed together by adhesive or welding; through the fixed connection of the side ear 110 and the connecting part 22, the inner liner 1 and the outer shell 2 can be integrated into a single structure.
[0033] Understandably, this application replaces traditional stainless steel or glass cups with sterling silver cups. Based on the inherent properties of silver ions, they can disinfect and purify the water inside the cup, thereby improving drinking water quality. Furthermore, they can slow down the oxidation and decomposition of organic matter in the water, reducing odors. Drinking water from sterling silver cups can be beneficial to a user's health.
[0034] It should be noted that there are two main paths for heat transfer on the inner liner 1. One is through the pressing part 11 of the inner liner 1 to the outer shell 2 via heat conduction. The other is through the heat radiation of the inner liner 1 to the outer shell 2. Traditional double-walled water cups mostly avoid reducing heat radiation by drawing a vacuum. However, since silver is relatively soft, drawing a vacuum directly may cause the silver cup to deform.
[0035] Furthermore, in order to reduce heat transfer from the inner liner 1 to the outer shell 2, such as... Figure 1 As shown, an insulation layer is filled inside the receiving cavity 21 to insulate against heat. The insulation layer inside the receiving cavity 21 is attached to the outer wall of the inner liner 1. When the temperature of the inner liner 1 rises, the insulation layer can block the heat, effectively reducing heat transfer and achieving the effects of preventing scalding and heat insulation. In addition, a heat dissipation component is also provided between the outer shell 2 and the inner liner 1. When the heat on the inner liner 1 is conducted to the outer shell 2 through this connection point, the heat dissipation component can absorb some of the heat to prevent all the heat from being conducted into the outer shell 2.
[0036] Specifically, the insulation layer is made of expanding foam. When the expanding foam is filled into the cavity 21, it can trap the heat transmitted from the inner liner 1, thereby reducing the overall amount of heat conducted to the outer shell 2 through the air. In addition, the expanding foam also plays a role in shock absorption and positioning, which can prevent the inner liner 1 from shifting position.
[0037] In this embodiment, as Figure 1 and Figure 2 As shown, the heat dissipation assembly includes a cup lug 4, with an annular protrusion 41 on the inner side of the cup lug 4, and an annular groove 23 on the connecting part 22 for mounting the annular protrusion 41. During installation, the cup lug 4 can be directly fitted onto the outer shell 2, at which point the annular protrusion 41 is embedded in the annular groove 23, thereby radially limiting the cup lug 4. Then, the side lug 110 is fitted against the upper end face of the annular protrusion 41; wherein the diameter of the side lug 110 is larger than the diameter of the annular protrusion 41. When the side lug 110 is fixedly connected to the connecting part 22, the side lug 110 can axially limit the annular protrusion 41. In this way, the position of the cup lug 4 can be fixed.
[0038] It is understandable that the cup handle 4 is in contact with both the outer shell 2 and the inner liner 1. When heat is transferred from the inner liner 1, the cup handle 4 can absorb the heat from the inner liner 1 and the outer shell 2 to prevent the outer shell 2 from getting too hot.
[0039] It should be noted that the cup handle 4 in this embodiment is made of zinc alloy, which has strong heat dissipation properties and can quickly absorb heat from the outer shell 2 and the inner liner 1. Of course, in some other embodiments of this application, zinc alloy can be replaced with magnesium alloy or other materials that also have good heat dissipation properties. When using the double-walled silver cup, the user generally places their hand on the outer wall of the outer shell 2 and does not directly contact the cup handle 4. Therefore, the temperature rise of the cup handle 4 will not affect the user's experience. Furthermore, the cup handle 4 can be designed in different shapes to improve the aesthetics and practicality of the double-walled silver cup. For example, designing the cup handle 4 as an arc can provide guidance when pouring water from the double-walled silver cup, causing the hot water to flow out at a specific point.
[0040] In this embodiment, as Figure 1 and Figure 5 As shown, the double-walled silver cup also includes a lid 3. After the inner liner 1 is connected to the shell, the top of the inner liner 1 protrudes from the handle 4. The diameter of the lid 3 is larger than the diameter of the pressing part 11, so that the lid 3 can completely cover the open part of the inner liner 1. Inserting the lid 3 into the handle 4 can keep the water in the inner liner 1 warm and sealed. In addition, the lid 3 can be removed and used as a cup, and the water in the inner liner 1 can be poured directly into the lid 3 for drinking. Considering the stability of the lid 3 when used as a cup, a protrusion 31 can be provided on the top of the lid 3. When the lid 3 is placed upside down on a table, the protrusion 31 can fit against the table surface, thereby preventing the lid 3 from shaking. Furthermore, since drinking water stays in the inner liner 1 most of the time and is only poured into the lid 3 when drinking, the lid 3 can be replaced with other materials besides silver. Those skilled in the art can choose according to actual needs.
[0041] Furthermore, to prevent the lid 3 from separating from the outer shell 2 when the double-walled silver cup is shaken, a mutually cooperating limiting structure is provided between the outer wall of the pressing part 11 and the inner wall of the lid 3. The limiting structure can fix the lid 3 to the pressing part 11 to prevent the lid 3 from falling off when the double-walled silver cup is carried.
[0042] Specifically, such as Figure 2 As shown, the limiting structure is a limiting block 200. A portion of the wall surface of the pressing part 11 is recessed inward to form a limiting groove 111. The limiting block 200 is fixedly installed within the limiting groove 111, and the thickness of the limiting block 200 is greater than the depth of the limiting groove 111, allowing the limiting block 200 to protrude from the pressing part 11 and engage with the cup lid 3. The mating surfaces of the limiting block 200 and the cup lid 3 are provided with mutually engaging threaded structures. When the cup lid 3 is closed, rotating the cup lid 3 seals the water in the inner liner 1 through the mutually engaging threaded structure, preventing hot water from spilling out and scalding the user, further improving the safety of the double-walled silver cup.
[0043] It should be noted that, in addition to threaded fit, the limiting block 200 and the cup lid 3 can also be limited by interference fit, magnetic fit, or other methods.
[0044] It should be understood that, considering the presence of a cavity 21 between the bottom of the inner liner 1 and the bottom of the outer shell 2, when water is placed in the inner liner 1, the overall center of gravity of the double-layered silver cup will shift upwards. In this case, if the double-layered silver cup is subjected to a slight impact, it may tip over, posing a certain safety hazard. Therefore, in some embodiments of this application, a counterweight can be provided at the lower part of the outer shell 2 to lower the center of gravity of the double-layered silver cup, thereby reducing the probability of tipping over and further improving the safety of the double-layered silver cup.
[0045] In this embodiment, as Figure 6 and Figure 7 As shown, the pressing part 11, in conjunction with the side wall of the inner liner 1, forms a downward-opening mounting groove 112. The top end of the connecting part 22 is folded upward to form an insert 220. Since the contact area between the connecting part 22 and the side lug 110 becomes larger after folding, the installation stability of the inner liner 1 and the outer shell 2 can be further improved. During the installation of the inner liner 1 and the outer shell 2, the insert 220 is inserted into the mounting groove 112. Some of the heat from the inner liner 1 and the outer shell 2 can be directly transferred to the insert 220, and the insert 220 will not come into direct contact with the user's hand. Therefore, the heat on the parts of the outer shell 2 that come into direct contact with the user will be further reduced.
[0046] Specifically, such as Figure 7As shown, a rubber pad 300 is installed at the bottom of the mounting groove 112. A slot for inserting the insert 220 is provided on the side of the rubber pad 300 near the insert 220. When heat is transferred from the inner liner 1 to the outer shell 2, some of the heat is transferred to the rubber pad 300, thereby reducing the heat transferred from the inner liner 1 to the outer shell 2. The slot on the rubber pad 300 can be used to position the insert 220; when the insert 220 is inserted into the slot, it is the correct installation point.
[0047] The basic principles, main features, and advantages of this application have been described above. Those skilled in the art should understand that this application is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this application. Various changes and modifications can be made to this application without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection claimed by this application is defined by the appended claims and their equivalents.
