Description

Technical Field

[0001] This utility model relates to the field of electric water cup technology, and in particular to a lightweight electric water cup. Background Technology

[0002] During extended outdoor activities such as hiking, traveling, and setting up a stall, ensuring adequate and appropriately warm water intake is crucial for maintaining normal physiological functions. Currently, in outdoor settings, people mainly rely on insulated cups to store hot water to meet their drinking needs.

[0003] While insulated cups have solved the problem of obtaining hot water outdoors to some extent, they have obvious limitations. On the one hand, the water storage capacity of insulated cups is limited. Once the hot water stored inside is consumed, it will be difficult for users to obtain hot water again in outdoor environments where there is no external source of hot water. On the other hand, insulated cups are not completely heat-insulating. The heat of the hot water inside will gradually dissipate over time, and after a period of time, the water temperature will drop to an unsuitable drinking temperature, making it difficult to meet users' needs for a continuous and stable supply of hot water during long-term outdoor activities.

[0004] In conclusion, the existing method of storing hot water in thermos cups cannot fully meet people's hot water needs during outdoor activities. There is an urgent need to develop a new type of water heating device suitable for outdoor activities to solve the problems of insufficient hot water supply and difficulty in maintaining water temperature during outdoor activities. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can solve the above problems.

[0006] A lightweight electric water cup includes a cup holder, a cup body mounted on the cup holder, and a cup lid covering the cup body. The cup holder integrates a lithium battery module and a circuit module electrically connected to the lithium battery module. Multiple elastic conductive contacts are located at the upper end of the cup holder. An enclosure is formed upwards along the edge of the cup holder, and a connecting piece is provided on the enclosure. A positioning structure is provided between the cup body and the cup holder, enabling the cup body to be oriented onto the cup holder, and the cup holder protects the cup body through the enclosure. Multiple conductive sheets abutting the elastic conductive contacts are located at the lower end of the cup body. A thick-film heating element and a temperature sensor are integrated inside the cup body, acting on the inner bottom of the cup body. The thick-film heating element and the temperature sensor are electrically connected to different conductive sheets.

[0007] Preferably, the positioning structure includes a positioning slot formed on the cup holder and a positioning block formed at the lower end of the cup body. The cup holder is oriented on the cup holder by the mating cooperation of the positioning block and the positioning slot.

[0008] Preferably, a stepped portion is formed on the cup holder, and a groove portion is formed at the lower end of the cup body to engage with the stepped portion. The cup holder and the cup body are initially positioned by engaging the stepped portion and the groove portion. An elastic conductive contact head is disposed in the middle of the stepped portion, a conductive sheet is disposed in the middle of the groove portion, and a positioning structure is disposed between the stepped portion and the groove portion.

[0009] Preferably, a first magnetic ring is arranged around the stepped portion, and a second magnetic ring corresponding to the first magnetic ring is arranged around the groove portion. The stepped portion and the groove portion are mutually constrained by the magnetic attraction between the first magnetic ring and the second magnetic ring.

[0010] Preferably, a trigger, a charging interface, and an indicator light are provided on the side of the cup holder, and the trigger, the charging interface, and the indicator light are electrically connected to the circuit module.

[0011] Preferably, the enclosure includes an enclosure ring that can be fitted onto the cup body and multiple longitudinal strips formed downward along the enclosure ring. The multiple longitudinal strips are fixedly connected to the outer periphery of the cup holder, and the strips with connectors are disposed on the outer periphery of the enclosure ring.

[0012] Preferably, anti-slip rings are provided around the lower end of both the cup body and the lower end of the cup holder.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] In terms of portability, the combination design of the cup holder, cup body, and lid is not only compact and easy to carry, meeting people's needs for lightweight drinking devices during outdoor activities such as hiking, traveling, and setting up stalls, but also features a surrounding part and a connecting piece along the edge of the cup holder. Through this connecting piece, users can easily connect a shoulder strap or other structure to conveniently wear the cup holder on their body. This frees up their hands while ensuring that the water cup is always readily available, greatly improving the convenience of using a water cup during outdoor activities. Furthermore, the cup holder and cup body adopt a separate structure. From a weight distribution perspective, the separate design avoids the weight concentration caused by the excessive integration of the overall structure, so that users do not need to hold the cup holder when drinking water. When carrying the cup, if the heating function is not needed, users can carry only the cup body, which greatly reduces the burden of carrying it. In addition, in terms of functionality, the positioning structure and conductive connection between the cup body and the cup holder realize a convenient heating function, which effectively solves the problems of limited hot water volume and easy heat loss of traditional thermos cups. It ensures that users can heat room temperature water into hot water suitable for drinking at any time outdoors. Moreover, this internally integrated lithium battery module eliminates the dependence on external power source and improves the flexibility of use.

Detailed Implementation

[0024] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0025] Please see Figure 1-5In this embodiment of the present invention, a lightweight electric water cup includes a cup holder 10, a cup body 20 disposed on the cup holder 10, and a cup lid 30 covering the cup body 20. The cup lid 30 and the cup body 20 adopt a traditional threaded tightening structure. The cup holder 10 integrates a lithium battery module 11 and a circuit module 12 electrically connected to the lithium battery module 11. Multiple elastic conductive contacts 13 are provided at the upper end of the cup holder 10. An enclosing portion 14 is formed upward along the edge of the cup holder 10, and a... A connector 15 is provided; a positioning structure 40 is provided between the cup body 20 and the cup holder 10, so that the cup body 20 can be oriented and positioned on the cup holder 10, and the cup holder 10 protects the cup body 20 through the enclosure part 14. Multiple conductive sheets 21 are provided at the lower end of the cup body 20 and are connected to the elastic conductive contact head 13. A thick film heating element 22 and a temperature sensor 23 acting on the inner bottom of the cup body 20 are integrated inside the cup body 20. The thick film heating element 22 and the temperature sensor 23 are electrically connected to different conductive sheets 21 respectively.

[0026] In the above technical solution, the cup body 20 is oriented and placed on the cup holder 10. At this time, the conductive sheet 21 at the lower end of the cup body 20 and the elastic conductive contact head 13 at the upper end of the cup holder 10 are precisely connected, thereby establishing a complete circuit connection. The lithium battery module 11 integrated inside the cup holder 10 serves as the power source of the entire device, outputting electrical energy. The circuit module 12 plays a key role in this process. It can convert the electrical energy output by the lithium battery module 11 and adjust it to a specific specification, such as 7.4V, 65W electrical energy. After conversion, the electrical energy is smoothly transmitted to the thick film heating element 22 integrated inside the cup body 20 through the elastic conductive contact head 13. When the heating function is activated, the current flows in the thick film heating element 22, according to the focus... According to the law of the ear, electrical energy is converted into heat energy, and the thick film heating element 22 heats up rapidly, thereby heating the water at the bottom of the cup body 20. During the heating process, the temperature sensor 23 monitors the water temperature in the cup in real time and continuously feeds back the temperature signal to the circuit module 12. Once the water temperature reaches the preset temperature, the circuit module 12 automatically adjusts the current based on the signal fed back by the temperature sensor 23, or directly cuts off the circuit to stop heating. For example, when the water temperature is heated to 50°C, the current is automatically adjusted, or the circuit is directly cut off. When the water temperature drops to 36°C, the heating function is activated to continue heating the water, thereby ensuring that the water temperature remains stable within the set range and achieving precise control of the water temperature in the cup.

[0027] With this design, the cup holder 10, cup body 20 and cup lid 30 are not only compact and easy to carry, meeting people's needs for lightweight drinking devices during outdoor activities such as hiking, traveling, and setting up stalls, but also the cup holder 10 can be easily connected to a shoulder strap or other structure by the enclosing part 14 and the connecting piece 15 on the edge of the cup holder 10. This allows users to conveniently wear the cup holder 10 on their body, freeing up their hands while ensuring that the water cup is always readily available, greatly improving the convenience of using the water cup during outdoor activities. Furthermore, the cup holder 10 and the cup body 20 adopt a separate structure. From the perspective of weight distribution, the separate design avoids the weight concentration caused by the excessive integration of the overall structure, so that users do not need to hold the cup holder 10 when drinking water. When carrying the water cup, if the heating function is not needed, users can carry only the cup body 20, which greatly reduces the burden of carrying. In addition, in terms of functionality, the positioning structure 40 and the conductive connection between the cup body 20 and the cup holder 10 realize a convenient heating function, effectively solving the problem of limited hot water volume and easy loss of water temperature in traditional thermos cups. This ensures that users can heat room temperature water into hot water suitable for drinking at any time outdoors. Moreover, this internally integrated lithium battery module 11 eliminates the dependence on external power source and improves the flexibility of use.

[0028] Taking a cup body 20 with a capacity of 500ml, providing 7.4V and 65W of power, and a lithium battery module 11 with a capacity of 10000mAh as an example, according to the energy formula E=UIt, where E is energy, U is voltage, I is current, and t is time, and It is the amount of electricity Q, then the total energy E=UQ. Converting the amount of electricity to the international unit coulomb 10000mAh=10A✖3600s=36000C, then the total energy E=7.4V✖36000C=266400J. Given that the power of the electric water cup P=65W, this means that the electric water cup consumes 65 joules of energy per second to maintain heating.

[0029] In reality, a water cup loses heat to the surrounding environment. Let's assume the heat dissipation power of the water cup is P. 散 Furthermore, to maintain a constant heat dissipation power during the heat preservation process and keep the water temperature at 50 degrees Celsius, the heating power of the electric water cup must equal the heat dissipation power, i.e., P=P 散 Assuming the water cup is heated from room temperature to 50 degrees Celsius and the timing begins, and all the energy consumed by the electric water cup is used to replenish the lost heat, then, according to the law of conservation of energy, the total energy E stored in the lithium battery module 11 divided by the heat dissipation power P... 散 It refers to the heat preservation time t, i.e., t = E / P. 散 However, the heat dissipation power P 散It's difficult to calculate precisely, as it depends on factors such as the material of the cup, the ambient temperature, and the airflow speed. Generally speaking, for a typical 500ml electric water cup at room temperature (around 25 degrees Celsius), the heat dissipation power is likely around 5W-15W. If we take the heat dissipation power P... 散 =10W, then the heat preservation time t=266400J / 10W=26640s≈7.4h.

[0030] like Figure 3-5 As shown, in the design of the positioning structure 40, the positioning slot 41 and the positioning plug 42 are used to provide a precise orientation installation method for the cup body 20 and the cup holder 10. This design ensures that every time the cup body 20 is placed on the cup holder 10, the conductive sheet 21 at the lower end of the cup body 20 can accurately connect with the elastic conductive contact head 13 on the cup holder 10, ensuring the stability of power transmission and avoiding poor contact due to position deviation, which would affect the heating function. At the same time, the precise positioning also enhances the structural stability of the cup body 20 and the cup holder 10 after combination, reducing the risk of the cup body 20 shifting due to shaking and bumping during outdoor activities. Furthermore, a stepped portion 16 can be formed on the cup holder 10, and a groove portion 24 that engages with the stepped portion 16 is provided at the lower end of the cup body 20. The stepped portion 16 on the cup holder 10 engages with the groove portion 24 at the lower end of the cup body 20, which serves as a preliminary positioning function, greatly simplifying the installation process. Users do not need to repeatedly adjust the position of the cup body 20, and can quickly place the cup body 20 in a roughly accurate position, improving the convenience of operation. The elastic conductive contact head 13 and the conductive sheet 21 are respectively set in the middle of the stepped portion 16 and the groove portion 24, and together with the positioning structure 40, further ensure the accuracy and reliability of the circuit connection.

[0031] like Figure 4-5 As shown, regarding the stability of the connection between the cup body 20 and the cup holder 10, this technical solution uses a first magnetic ring 17 arranged around the step portion 16 and a second magnetic ring 25 corresponding to the first magnetic ring 17 arranged around the groove portion 24. The step portion 16 and the groove portion 24 are mutually constrained by the magnetic attraction of the first magnetic ring 17 and the second magnetic ring 25. This magnetic attraction between the first magnetic ring 17 and the second magnetic ring 25 makes the two more tightly connected, enhances the stability of the overall structure, and effectively prevents the cup body 20 from accidentally falling off. Especially in complex outdoor environments, such as walking on bumpy mountain roads or during frequent movement, the magnetic constraint can ensure that the cup body 20 and the cup holder 10 always remain connected, ensuring the normal operation of hot water heating and storage functions.

[0032] In terms of circuit structure design, a trigger 121, a charging interface 122, and an indicator light 123 are provided on the side of the cup holder 10. The trigger 121, the charging interface 122, and the indicator light 123 are electrically connected to the circuit module 12. The trigger 121 on the side of the cup holder 10 facilitates user operation and control of the heating function, making operation intuitive and convenient. The charging interface 122 facilitates charging of the lithium battery module 11 inside the cup holder 10, ensuring a continuous power supply during outdoor activities. The indicator light 123 can provide real-time feedback on the product's working status, such as charging status and heating status, allowing users to clearly see the status, improving the user experience, and avoiding misoperation due to a lack of understanding of the device's status.

[0033] In terms of structural design, the enclosure 14 adopts an enclosure ring 141 and multiple longitudinal strips 142. The enclosure ring 141 can be tightly fitted onto the cup body 20, providing good protection for the cup body 20 and preventing it from being damaged by collisions or scratches during outdoor activities. The multiple longitudinal strips 142 are fixedly connected to the outside of the cup holder 10, enhancing the connection strength between the enclosure 14 and the cup holder 10. A connector 15 is set around the enclosure ring 141 to facilitate the connection of a shoulder strap, shoulder strap, etc., enabling convenient carrying of the water bottle and meeting the user's need to free their hands in different outdoor activity scenarios.

[0034] In addition, anti-slip rings 50 are set around the lower end of the cup body 20 and the lower end of the cup holder 10, which significantly increases the friction between the cup and the surface on which it is placed. Whether the cup is placed on an outdoor rock, table, or sloping ground, the anti-slip rings 50 can effectively prevent the cup from sliding or tipping over, ensuring the safety of hot water storage and avoiding hot water spillage caused by the cup tipping over, which could lead to scalding or other safety accidents. This improves the stability and reliability of the product in various usage scenarios.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
