Description

Technical Field

[0001] The present application relates to the field of household life, and specifically to a smart water cup heating and insulation sticker and a water cup. Background Art

[0002] In today's society, with the enhancement of health awareness, drinking water in moderation has become an important part of people's daily lives. According to the recommendation of health experts, an adult needs to consume 1500 to 2000 ml of water every day to maintain the normal functioning of the body. However, in real life, especially in winter, people often encounter the problem of finding that the tea at hand has cooled down quickly when they want to drink warm water. The results of the questionnaire survey show that as many as 58% of people have experienced the helpless feeling of finding that the tea has cooled down when they want to drink water. In addition, during long meetings or long-distance travel, the problem of keeping water or drinks warm will also be encountered. If you cannot get warm water in time when you are thirsty, this will directly lead to a decrease in water intake, which in turn affects your personal health.

[0003] In response to this common problem, some devices have been launched on the market to solve the problem of keeping drinking water warm. These devices can be roughly divided into two categories: one is a heating plate, which keeps the water temperature by heating the bottom of the water cup; the other is a barrel-type insulation cover, which achieves the effect of insulation by wrapping the cup body. However, both solutions have certain limitations. For the heating plate, there are specific requirements for the size and material of the water cup it is suitable for. It is mainly suitable for glass or stainless steel cups, but not for cups made of plastic and other materials, and its versatility is poor. In addition, there is a risk of scalding when using a heating plate. Although the barrel-type insulation cover can provide a certain insulation effect, its size is relatively fixed and cannot adapt to cups of different calibers. It is even more difficult to apply to cups with handles, and the application scenarios are limited. Summary of the invention

[0004] The purpose of this application is to provide a smart water cup heating and insulation sticker and a water cup, which can be fitted to various water cups, heat faster, have a more balanced temperature, and have higher safety.

[0005] The present application discloses a smart water cup heating and heat preservation sticker, comprising: an outer heat preservation layer 1, at least two memory metal springs 2, an outer waterproof layer 3, a heating layer 4, an inner waterproof layer 5 and a USB connector 6;

[0006] The outer insulation layer 1, the memory metal spring 2, the outer waterproof layer 3, the heating layer 4 and the inner waterproof layer 5 are sequentially combined from outside to inside to form a heating insulation composite layer 7, and the memory metal spring 2 is configured to switch between a bending state and a straightening state by an external force so that the heating insulation composite layer 7 can be removably surrounded and attached to the outer surface of the water cup;

[0007] The USB connector 6 is electrically connected to the heating layer 4 , and the USB connector 6 is configured to supply power to the heating layer 4 to make the heating layer 4 generate heat.

[0008] In a preferred example, the heating layer 4 is a graphene heating film, the graphene heating film is provided with pins extending outward, and the USB connector 6 is welded and connected to the pins;

[0009] The graphene heating film is configured to convert the electrical energy supplied by the USB connector 6 into thermal energy.

[0010] In a preferred example, in the straightened state, the memory metal spring 2 is an arched surface, and the arched surface is configured to support the memory metal spring 2 to prevent the memory metal spring 2 from automatically bending.

[0011] In a preferred example, the heating layer 4 is an electric heating layer, in which heating wires laid in parallel or in a grid are buried, and the USB connector 6 is connected to the heating wires to realize power supply.

[0012] In a preferred example, the USB connector 6 is provided with a gear adjustment button 8, and the gear adjustment button 8 is configured to adjust the temperature gear of the heating layer 4 after being pressed, and the temperature gears include 45°C gear, 55°C gear and 65°C gear.

[0013] In a preferred example, a variable resistor is provided between the USB connector 6 and the heating layer 4, and the variable resistor is a knob-type variable resistor. The first end of the variable resistor is connected to the USB connector 6, and the sliding contact of the variable resistor is connected to the heating layer 4. The variable resistor is configured to rotate the knob to change the resistance value of the variable resistor to adjust the current flowing through the heating layer 4.

[0014] In a preferred example, a power supply is also included, and the USB connector 6 is connected to the power supply.

[0015] The present application also discloses a water cup, comprising the smart water cup heating and insulation patch as described in any one of the above items, and a water cup body 9.

[0016] In a preferred example, the distance between the upper edge of the smart water cup heating and insulation sticker and the cup mouth of the water cup body 9 is 20mm-30mm.

[0017] In a preferred example, the shape of the smart water cup heating and insulation sticker when attached to the smart water cup is C-shaped or O-shaped.

[0018] In the implementation mode of the present application, a composite structure design of an outer insulation layer, a memory metal spring, an outer waterproof layer, a heating layer and an inner waterproof layer is adopted. This multi-layer composite structure not only provides excellent insulation effect and prevents heat from being lost through radiation, convection and conduction, but also effectively protects the heating layer and prolongs the service life of the product. In particular, the outer insulation layer provides additional heat insulation protection for heat preservation, so that hot water or beverages can maintain a suitable drinking temperature for a long time. The memory metal spring can be switched between a bent state and a straightened state by an external force, allowing the heating insulation patch to intelligently adapt to water cups of different shapes and sizes, thereby solving the problem that traditional heating devices cannot adapt to different water cups. In addition, the design of power supply through a USB connector allows the heating insulation patch to not only be conveniently connected to USB power sources such as computers, mobile power supplies and car chargers, but also ensure high versatility and portability worldwide. The USB power supply method avoids the inconvenience of finding a specific power adapter, greatly improving the flexibility of user use, so it can be used in long meetings, long-distance travel and even outdoor activities.

[0019] Furthermore, the heating layer is a graphene heating film, which can quickly convert electrical energy into thermal energy, providing an instant heating effect, which is a huge advantage for users who need to quickly get warm drinks. Compared with traditional heating methods, the use of graphene heating film can achieve more efficient and uniform heating, ensuring that the drink maintains the ideal temperature for a longer period of time;

[0020] Furthermore, in the straightened state, the arched surface design of the memory metal spring makes the spring have a high structural stability. When the user does not need to use the smart water cup heating insulation sticker, after flattening it by external force, due to the arched surface of the memory metal spring, the smart water cup heating insulation sticker will not automatically return to the curved arc state in the flattened state;

[0021] Furthermore, by adjusting the gear button or the knob-type variable resistor, the user can control the temperature required for heating, making the application of the heating insulation patch more flexible.

[0022] A large number of technical features are recorded in the specification of this application, which are distributed in various technical solutions. If all possible combinations of technical features of this application (i.e., technical solutions) are to be listed, the specification will be too long. In order to avoid this problem, the various technical features disclosed in the above-mentioned invention content of this application, the various technical features disclosed in the various embodiments and examples below, and the various technical features disclosed in the accompanying drawings can be freely combined with each other to form various new technical solutions (these technical solutions are all deemed to have been recorded in this specification), unless the combination of such technical features is technically infeasible. For example, in one example, feature A+B+C is disclosed, and in another example, feature A+B+D+E is disclosed, and features C and D are equivalent technical means that play the same role. Technically, only one can be used, and it is impossible to use them at the same time. Feature E can be combined with feature C technically.

The memory metal spring 2 is configured to switch between a bent state and a straightened state by an external force so that the heating insulation composite layer 7 can be removably surrounded and attached to the outer surface of the water cup. The USB connector 6 is electrically connected to the heating layer 4, and the USB connector 6 is configured to supply power to the heating layer 4 to make the heating layer 4 heat up.

[0031] In an optional embodiment, a plurality of memory metal springs 2 are arranged in parallel along the long sides of the heating and heat-insulating composite layer 7 between the outer heat-insulating layer and the outer waterproof layer.

[0032] In an optional embodiment, the heating layer 4 is a graphene heating film, the graphene heating film is provided with outwardly extending pins, and the USB connector 6 is welded and connected to the pins;

[0033] The graphene heating film is configured to convert the electrical energy supplied by the USB connector 6 into thermal energy.

[0034] In an optional embodiment, in the straightened state, the memory metal spring 2 is an arched surface, and the arched surface is configured to support the memory metal spring 2 to prevent the memory metal spring 2 from automatically bending.

[0035] In an optional embodiment, the heating layer 4 is an electric heating layer, in which heating wires laid in parallel or in a grid are buried, and the USB connector 6 is connected to the heating wires to realize power supply.

[0036] In an optional embodiment, the USB connector 6 is provided with a gear adjustment button 8, which is configured to adjust the temperature gear of the heating layer 4 after being pressed, and the temperature gears include 45°C gear, 55°C gear and 65°C gear.

[0037] In an optional embodiment, a variable resistor is provided between the USB connector 6 and the heating layer 4. The variable resistor is a knob-type variable resistor. The first end of the variable resistor is connected to the USB connector 6. The sliding contact of the variable resistor is connected to the heating layer 4.

[0038] In an optional embodiment, a power supply is also included, and the USB connector 6 is connected to the power supply.

[0039] The second embodiment of the present application relates to a water cup, such as Figure 3 As shown, it includes a smart water cup heating and insulation sticker according to any one of the above solutions, and a water cup body 9.

[0040] In an optional embodiment, the distance between the upper edge of the smart water cup heating and insulation sticker and the cup mouth of the water cup body 9 is 20mm-30mm.

[0041] In an optional embodiment, the shape of the smart water cup heating and insulation sticker when attached to the smart water cup is C-shaped or O-shaped.

[0042] This embodiment is a product embodiment that includes the first embodiment, and the technical details in the first embodiment can be applied to this embodiment.

[0043] In order to better understand the technical solution of the present application, a specific example is provided below for illustration. The details listed in the example are mainly for ease of understanding and are not intended to limit the scope of protection of the present application.

[0044] The structure of the heating and heat-insulating composite layer 7 of the smart water cup heating and heat-insulating sticker of the present application is as follows from the outside to the inside: an outer heat-insulating layer 1, at least two memory metal springs 2, an outer waterproof layer 3, a heating layer 4, and an inner waterproof layer 5. In order to make the heating and heat-insulating composite layer 7 have a good waterproof function, the inner and outer sides of the heating layer 4 are wrapped with waterproof materials. The waterproof material can be selected from materials with good temperature resistance and physical stability such as polytetrafluoroethylene (PTFE), polyester (PET), and polyurethane (PU). In order to reduce heat loss, the outer heat-insulating layer 1 can be a cotton heat-insulating layer, or other materials can be used to provide a better heat-insulating effect, such as polyester fiber, polypropylene fiber, etc.

[0045] The heating and heat-insulating composite layer 7 of the present application utilizes two built-in memory metal springs 2 (memory metal strips) with a length of 215 mm to achieve automatic adaptive bonding to the outer wall of the water cup. The memory metal strip is designed as an arched surface, which can automatically maintain its bending state when not under force. When it is straightened by external force, the arched surface can effectively prevent itself from bending, thereby maintaining a straight state when the heating and heat-insulating composite layer 7 is not fixed to the water cup. Once the external force is eliminated, the memory metal strip can quickly return to its original bending state and tightly surround the outer wall of the water cup to achieve automatic bonding with water cups of different calibers. This adaptive bonding mechanism allows the heating and heat-insulating composite layer 7 to be used on water cups of different sizes, enhancing the versatility of the product.

[0046] The length of the heating and heat preservation composite layer 7 is about 220mm. According to research, the diameter of a common water cup without a handle on the market is 65mm±10mm, the circumference of the cup mouth is 204mm±10mm, and the height is 110-150mm; the diameter of a water cup with a handle is 85mm±10mm, the circumference of the cup mouth is 267mm±20mm, and the height is 90-130mm. For a water cup without a handle, the smart water cup heating and heat preservation sticker is directly enclosed on the outer wall of the water cup to form an O-shaped full enclosed shape (such as Figure 3For a water cup with a handle, the length of the smart water cup heating and insulation sticker can just enclose the outer wall of the water cup to form a C-shaped encirclement shape, and does not affect the use of the handle (as shown in C and D in FIG. Figure 3 In order to ensure the cleanliness of the cup mouth, the upper edge of the heating and heat-insulating composite layer 7 is at least 20 mm away from the cup mouth, so the height of the heating and heat-insulating composite layer 7 is about 70 mm, which is more reasonable. Considering the sizes of different water cups, the size of the heating and heat-insulating composite layer 7 can be designed to be 70 mm high and 220 mm long.

[0047] The method of using the smart water cup heating insulation sticker of this application is as follows:

[0048] Use your hands to push the rectangular heating and heat-insulating composite layer 7 toward the outer wall of the water cup body 9 in the direction of use. The heating and heat-insulating composite layer 7 automatically fits the outer wall of the water cup body 9 in a C-shape or an O-shape. Connect the USB connector 6 connected to the heating and heat-insulating composite layer 7 to a power source (which can be a portable mobile power source) for heating. If the USB connector 6 is provided with an adjustment gear button 8 or a variable resistor is provided between the USB connector 6 and the heating and heat-insulating composite layer 7, the gear required for heating (45°C gear, 55°C gear and 65°C) can be selected according to actual needs. When installing the heating and heat-insulating composite layer 7, try to avoid being too close to the mouth of the water cup to avoid affecting the cleanliness of the mouth of the cup.

[0049] When the heating process is completed or the insulation patch needs to be removed, the user can unplug the USB connector from the power supply and use a slight external force to restore the memory metal strip to a straight state, making it easier to remove the insulation patch from the water cup. This operation is simple, and the insulation patch in a straight state is more convenient for users to perform daily cleaning and carry and store the insulation patch. This design fully considers the convenience of use and the versatility of the product, providing users with an efficient and convenient heating and heat preservation solution.

[0050] This application is easy to operate, easy to carry, and has strong versatility. It can automatically fit cups of different calibers and materials for heat preservation and heating. It is suitable for home, office, travel (the car charging port can be used instead of a power bank) and other scenarios.
