Description

Technical Field

[0001] The present application relates to the technical field of cups and pots, and more particularly, to a cup lid and an electric heating cup. Background Art

[0002] With the improvement of people's living standards and the enhancement of health awareness, the demand for household drinking water heating equipment is also increasing continuously. Consumers are paying more and more attention to the convenience, safety, and health of drinking water. As a convenient and efficient household appliance, the electric heating cup is gradually becoming an essential item in modern life. It can be seen in various places such as offices, schools, and families. With the continuous improvement of consumers' demands for health, environmental protection, and convenience, as well as the continuous progress of technology and the reduction of costs, the market prospect of the electric heating cup is very broad.

[0003] The main function of an electric heating cup, as a household appliance, is to heat liquids, especially beverages such as water or tea, so as to quickly reach the drinking temperature. The core function of the electric heating cup is heating, and it does not directly provide a storage space for tea leaves. The storage of tea leaves requires certain conditions, such as dryness, light avoidance, and sealing, to maintain its freshness and flavor. The internal structure and materials of the electric heating cup are usually not suitable for long-term storage of tea leaves because it is mainly designed for heating and does not have the functions required for storing tea leaves, such as sealing and moisture-proof. Utility Model Content

[0004] In view of this, the present application provides a cup lid, an electric heating cup, and a detection method thereof, which improve the detection accuracy of residual stress.

[0005] In a first aspect, the present application provides a cup lid, which includes a lid body for connecting with a cup body and a storage bin detachably connected to the lid body. The lid body has a cavity, and a connecting portion for connecting with the cup body is provided on the inner side wall of the cavity. The storage bin is screwed and connected to one end of the lid body away from the connecting portion.

[0006] By adopting the above technical solution, the cup lid is composed of a lid body and a storage bin. The two parts are detachably connected. The cup lid is used to connect with the cup to close the cup mouth, and the lid body is used to store solid materials. This design not only facilitates cleaning and maintenance, but also increases the versatility of the cup lid. Users can choose whether to install the storage bin according to their needs, and can disassemble or install it at any time as needed. The storage bin is screwed to the end of the lid body far from the connecting part. This design makes it very convenient to open and close the storage bin. Users can easily open or close the storage bin by a rotating action without complicated operation steps. The existence of the storage bin provides a convenient storage space for users, where materials such as tea leaves, sugar packets, and wolfberries can be stored, enabling these items to be quickly retrieved when needed and avoiding the trouble of rummaging. The design of the entire cup lid fully considers the usage habits and needs of users. The separation and combination of the lid body and the storage bin can be achieved through simple rotating loading and unloading actions. This design not only improves the convenience of use, but also makes the cup lid more space-saving when carrying and storing.

[0007] In some embodiments, the storage bin has a storage cavity and an opening communicating with the storage cavity. When the opening end is screwed to the lid body, the lid body closes the opening to seal the storage cavity.

[0008] By adopting the above technical solution, when the opening end of the storage bin is screwed to the lid body, the lid body tightly closes the opening, thereby forming a sealed space for the storage cavity. The sealed storage cavity can effectively prevent dust, moisture or other pollutants from entering the interior of the storage bin, keeping the stored items clean and dry. This is particularly important for items that need to be kept fresh or dry, such as tea leaves and sugar packets.

[0009] In some embodiments, the end of the storage bin away from the opening has a support surface, and the support surface is parallel to the plane where the end surface of the lid body away from the storage bin is located.

[0010] By adopting the above technical solution, when the storage bin is screwed to the lid body, the support surface is parallel to the end surface of the lid body, which helps to form a stable support structure. This stability is beneficial to the stability when the cup lid is used as a teacup and a liquid is placed in the cavity, and the support surface is placed on the table, realizing the multi-functional performance of the cup lid.

[0011] In some embodiments, the storage bin includes an upper bin and a lower bin. The opening is located in the lower bin. A connecting structure for buckling with the upper bin is provided on the side of the lower bin away from the opening, and the support surface is located on the outer surface of the upper bin.

[0012] By adopting the above technical solutions, this split design makes the storage bin more flexible in structure and can be disassembled and reorganized as needed. Through the split design, the storage bin can be flexibly configured according to different usage scenarios and requirements. For example, users can choose whether to install the upper bin as needed to adjust the capacity or appearance of the storage bin. In addition, some special functional areas, such as partition boards, filter screens, etc., can be designed between the upper bin and the lower bin to meet the storage requirements of different items. Since the storage bin is divided into two parts, the upper bin and the lower bin, it is easier for users to clean and maintain it. For special structures, the two-body design is beneficial to mold manufacturing and processing.

[0013] In some embodiments, the connection structure includes a ring rib / ring groove located on the end face of the lower bin away from the opening side.

[0014] In some embodiments, a ring groove / ring rib that mates with the ring rib is provided on the end face of the upper bin away from the support surface.

[0015] In some embodiments, a retaining rib is provided on the inner surface of the lower bin near the ring rib, and the retaining rib prevents the upper bin from moving in the direction of the storage bin.

[0016] By adopting the above technical solutions, the shape and size of the ring groove match those of the ring rib. When the two are mated, a tight locking structure can be formed to ensure a stable and sealed connection between the upper bin and the lower bin. The retaining rib can maintain the stability of the assembled structure and is beneficial to improving the durability of the seal.

[0017] In some embodiments, a handle is connected between the storage bin and the cover body. The handle has a handle end and a connection end. The connection end is provided with a through hole, and the cover body is provided with a convex column, and the convex column passes through the through hole.

[0018] In some embodiments, the storage bin presses against the handle so that the handle exerts a reaction force on the storage bin, and this reaction force increases the static friction force of the screwed connection between the storage bin and the cover body.

[0019] By adopting the above technical solution, the design of the handle not only provides portability but also ingeniously enhances the connection stability between the storage bin and the lid. When the storage bin presses against the handle (for example, due to the interference fit of each component, the action of gravity during carrying, or the hand pressure of the user), the handle will exert a reaction force on the storage bin. This reaction force is transmitted to the convex post on the lid through the connection end of the handle and then acts on the entire lid. Since the storage bin and the lid are connected by screwing (such as threaded connection), this additional force will increase the contact pressure between them, thereby increasing the static friction force. The static friction force is the force that prevents two relatively stationary objects from starting to move relative to each other. In the connection between the storage bin and the lid, the increased static friction force means that a greater external force is required to overcome this friction force and separate the storage bin from the lid. Therefore, this design improves the firmness of the connection between the storage bin and the lid and reduces the risk of accidental opening during carrying or use.

[0020] In a second aspect, the present application provides an electric heating cup, including the cup lid of the first aspect.

[0021] By adopting the above technical solution, the cup lid on the electric heating cup integrates the storage bin design. Users can store small items such as tea leaves and sugar packets in the storage bin and access them at any time without the need to carry other containers or bags additionally, greatly improving the convenience of use.

[0022] In summary, the present application has at least one of the following beneficial technical effects:

[0023] 1. The cup lid of the present application realizes the perfect combination of convenience, practicality, and versatility through modular design and ingenious structural arrangement. This design not only improves the user experience but also meets the pursuit of modern people for the quality of life.

[0024] 2. The storage bin design fully considers the requirements of practicality and convenience, and provides a safe, hygienic, and convenient storage space for users through a sealed storage cavity and a convenient screwing connection method.

[0025] 3. The design of the handle not only provides portability for users but also ingeniously enhances the connection stability between the storage bin and the lid through mechanical principles.

[0026] 4. The electric heating cup of the present application has been significantly improved in terms of storage convenience, sealing performance, structural stability, humanized design, and versatility, bringing a more convenient, efficient, and comfortable use experience to users.

[0043] The following will describe in detail the embodiments of the present utility model with reference to the drawings. Without conflict, the features in the following embodiments can be combined with each other. Embodiment

[0044] Please refer to Figures 1 - 6 , the cup lid 1 provided by the embodiment of the present application includes a lid body 12 and a storage bin 11 detachably connected to the lid body 12.

[0045] Please refer to Figures 1 - 3 , the lid body 12 has a cavity 121. The inner side wall of the cavity 121 is provided with a first thread rib 122 for threaded connection with the cup body 2. The storage bin 11 is screwed to the end of the lid body 12 away from the first thread rib 122, achieving the effect of improving the connection stability between the storage bin 11 and the lid body 12 of the cup lid 1. The storage bin 11 includes an upper bin 111 and a lower bin 112. The upper bin 111 and the lower bin 112 enclose a storage cavity 113, and materials such as tea leaves can be stored in the storage cavity 113.

[0046] Please refer to Figure 1 , the storage bin 11 can be placed on the table below. The cavity 121 of the lid body 12 has an upward opening. In this state, boiling water or tea can be placed in the cavity 121, and the cup lid 1 can be used as a teacup.

[0047] Please refer to Figure 3 and Figure 4, the cover body 12 includes a cup mouth 22 sealing portion and a storage bin 11 joint portion. The cup mouth 22 sealing portion and the storage bin 11 joint portion are integrally formed to form the cover body 12. The cup mouth 22 sealing portion includes a first thread rib 122 and a sealing ring, and the sealing ring can be any one of a flat sealing ring and a flanged sealing ring to ensure good sealing between the cover body 12 and the cup body 2. The storage bin 11 joint portion includes a convex column 123 and a second screwing rib 124 provided on the side wall of the convex column 123. An opening 1121 communicating with the storage cavity 113 is provided at one end of the lower bin 112 away from the upper bin 111. A first screwing rib 1122 is provided on the side wall of the opening 1121. The cover body 12 and the lower bin 112 are screwed and connected and fixed through the first screwing rib 1122 and the second screwing rib 124 to ensure a tight connection between the storage bin 11 and the cover body 12.

[0048] When the opening 1121 end is screwed and connected with the cover body 12, the cover body 12 closes the opening 1121 to seal the storage cavity 113. The internal shape of the storage cavity 113 can be any one of a rectangle, a circle and an ellipse, and can be adjusted according to the actual use needs of users.

[0049] Please refer to Figure 5 and Figure 6 , the first screwing rib 1122 can be directly formed at the opening 1121 end through an injection molding technique or can be formed into threads through post-processing. The first screwing rib 1122 at the opening 1121 end can also be provided with anti-slip protrusions, and the anti-slip protrusions can be any one of a spiral structure and a protrusion dot structure to enhance the friction force when the user rotates and prevent damage or loosening of the storage bin 11 caused by hand slipping.

[0050] One end of the storage bin 11 away from the opening 1121 has a support surface 1113, and the support surface 1113 is parallel to the plane where the end surface of the cover body 12 away from the storage bin 11 is located. The support surface 1113 serves as the force-bearing surface when the storage bin 11 is placed, and its rigidity can be improved by setting reinforcing ribs to prevent deformation of the support surface 1113 after long-term use. The reinforcing ribs can be any one of an X-shaped and a grid-like structure to enhance the stability of the support surface 1113. The parallel design between the support surface 1113 and the cover body 12 can not only ensure the balance of the storage bin 11, but also make the connection between the storage bin 11 and the cup cover 1 more tightly stable.

[0051] On one side of the lower bin 112 far from the opening 1121, there is a connection structure for buckling with the upper bin 111, and the support surface 1113 is located on the outer surface of the upper bin 111. The connection structure includes a ring rib 1124 on the end face of the lower bin 112 on the side far from the opening 1121. The ring rib 1124 can be one or more circles of annular protrusions to increase the contact area of the connection surface and improve the sealing performance. On the end face of the upper bin 111 on the side far from the support surface 1113, there is a ring groove 1112 that cooperates with the ring rib 1124. The ring groove 1112 can be one or more annular grooves with different depths so that the ring rib 1124 can be accurately embedded into the ring groove 1112 to achieve a reliable connection between the upper and lower bins 112. In addition, a sealing ring can be arranged in the ring groove 1112, and the sealing ring can be an O-ring or other types of sealing rings to prevent the leakage or dampness of the items in the storage bin 11. A rib locking structure is arranged between the ring rib 1124 and the ring groove 1112, and the rib locking structure prevents the upper bin 111 from moving towards the storage bin 11. The rib locking structure can be one or several convex ribs perpendicular to the ring rib 1124 to prevent the separation between the upper bin 111 and the lower bin 112. The rib locking includes two first rib lockings 1111 arranged on the inner side wall of the upper bin 111 and a second rib locking 1123 arranged on the inner side wall of the lower bin 112. The second rib locking 1123 is inserted and matched with the two first rib lockings 1111 to achieve the reliability of the connection. The rib locking structure is arranged in multiple groups circumferentially and uniformly along the inner wall of the storage cavity 113. The connection between the upper bin 111 and the lower bin 112 can also be further improved in connection stability by setting structures such as hooks or tenons. In addition, the connection between the upper bin 111 and the lower bin 112 can also adopt a magnetic connection method, and the reliability of the connection can be increased by setting a permanent magnet or an electromagnet.

[0052] The implementation principle of this embodiment is as follows: By setting the second screwing rib 124 on the cover body 12 and the matching first screwing rib 1122 on the storage bin 11, the tight connection between the storage bin 11 and the cover body 12 can be ensured. The setting of the support surface 1113 not only improves the balance of the storage bin 11 during support, but also makes the overall storage bin 11 more stable and firm due to the reliable connection structure between the upper bin 111 and the lower bin 112. The support surface 1113 can be a plane or multiple protrusions with the same plane support points. Embodiment

[0053] Please refer to Figures 7 - 9, The difference between this embodiment and the above-mentioned embodiment is that a handle 13 is connected between the storage bin 11 and the cover 12. The handle 13 is provided with a handle end 133 and a connection end 131. The connection end 131 is provided with a through hole 132, and the cover 12 is provided with a convex post 123. The convex post 123 passes through the through hole 132 and is connected to the lower bin 112. The handle 13 is made of an elastic material, and in this embodiment, the handle 13 is made of silicone. The thickness of the connection end 131 is greater than the height for placing the connection end 131 after the lower bin 112 and the cover 12 are screwed together. After the cover 12 and the lower bin 112 are screwed together, the connection end 131 of the handle 13 is squeezed to deform the connection end 131. The deformation reaction force of the connection end 131 increases the static friction between the lower bin 112 and the cover 12 and reduces the probability of the two coming loose. The design of the handle 13 not only provides a means for convenient user carrying, but also can increase the friction between the storage bin 11 and the cover 12 through the ingenious structure of the handle end 133, further improving the connection stability.

[0054] The handle 13 can be of various shapes, such as any one of a circular ring shape and an oval shape. The handle end 133 can be designed in a form with an adjustable length, so that the length of the handle 13 can be freely adjusted according to user needs. In addition, the handle end 133 can also be provided with anti-slip textures, such as any one of a wave pattern and a diamond pattern, to increase the friction between the handle 13 and the hand.

[0055] The convex post 123 can be any one of a variety of shapes, such as a cylinder and a convex post 123 with a thread. The fit between the convex post 123 and the through hole 132 can be adjusted according to the actual situation to ensure that the handle 13 will not come off the cover 12 during use. In this embodiment, the diameter of the through hole 132 is slightly smaller than the outer diameter of the convex post 123. In order to improve the connection stability, a snap ring or other clamping structures can also be provided between the convex post 123 and the through hole 132 to ensure that the handle 13 is firmly fixed on the cover 12.

[0056] The storage bin 11 presses against the handle 13 so that the handle 13 exerts a reaction force on the storage bin 11. This reaction force increases the static friction of the threaded connection between the storage bin 11 and the cover 12. The pressing force of the storage bin 11 can be achieved by adjusting the design of the handle 13, such as setting an elastic deformation structure. The handle 13 can be designed as a split structure. The side close to the storage bin 11 can be set as an elastic deformation structure, such as any one of a spring piece and elastic rubber, so that it generates a certain deformation force during use, further increasing the friction between the storage bin 11 and the cover 12, thereby enhancing its stability.

[0057] The implementation principle of this embodiment is as follows: By setting the handle 13 connection structure, it not only makes it more convenient for users to carry, but also can further enhance the connection stability between the storage bin 11 and the lid 12 through the handle 13 structure. The design of the handle end 133 increases the diversity of functions, making the use experience of the cup lid 1 more optimized. Embodiment

[0058] Please refer to Figure 8 、 Figure 10 、 Figure 11 This embodiment provides an electric heating cup, which includes the cup lid 1 and the cup body 2 in Embodiment 1 or Embodiment 2. The cup body 2 has a cup mouth 22 and a second thread rib 21. The second thread rib 21 is threadedly connected to the first thread rib 122 on the lid 12 so that the cup lid 1 seals the cup mouth 22. The electric heating cup has a heating function and can heat the drink in the cup in a short time, improving the user's convenience and comfort in use.

[0059] Inside the cup body 2 of the electric heating cup, there are a heating element, a temperature control element and a power supply module. The heating element can be either an electric heating wire or an electric heating film. The temperature control element can be a temperature control chip or a temperature control switch to accurately control the heating temperature. The power supply module can use a lithium battery to provide stable power for the heating element. In addition, a heat insulation layer can be provided around the outside of the cup body 2 to prevent the user from being scalded during use.

[0060] The design of the cup lid 1 is the same as the above embodiment, including a lid body 12 and a storage bin 11. A heating accessory, such as a heating coil, can be provided inside the cup lid 1 and connected to the battery in the cup body 2 through wireless charging technology. In this way, the cup lid 1 can not only play a sealing role, but also provide a heating function for the drink in the cup. The heating accessory can also be connected to the temperature control element in the cup body 2 to achieve precise temperature adjustment by controlling the power of the heating accessory.

[0061] A charging interface can be provided at the bottom of the electric heating cup to charge the battery in the cup through a USB interface. When the user needs to use the electric heating cup, they only need to connect the cup body 2 to the power supply, and the heating function can be achieved without removing the cup lid 1. In addition, the design of the storage bin 11 of the cup lid 1 enables the user to conveniently carry small items, enhancing the practicality of the cup.
