[0002] Thermos cups are being used more and more frequently; however, because of their heat preservation effect, people are easily scalded if the water temperature is too high. Therefore, more and more thermos cups have temperature measurement functions, but currently, the temperature detection device of thermos cups is mostly located on the cup cover, which leads to inaccurate temperature measurement.

[0003] In addition, during the use of a thermos, one can usually drink water simply by opening the cup cover. However, existing smart thermos cups often contain a variety of electrical components, such as temperature measuring devices and cup cover electronic control switches. Since most of these electrical components are located in the cup cover, the cup cover becomes heavy, which affects the opening of the cup cover. For example, a cup lid and liquid containing device are disclosed in application number 202411258370.5. Utility Model Content

[0009] The detection mechanism, located in the middle frame assembly, is used to detect the temperature of the liquid inside the cup;

[0010] Electronic components are disposed within the middle frame component.

[0038] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0039] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0040] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0041] like Figures 1-7As shown, this embodiment provides a cup lid 1, which includes a screw thread assembly 10, a middle frame assembly 20, a cup cover 30, a locking member 60, a first control assembly 40, and a second control assembly 50. The screw thread assembly 10 is used for rotatably mounting to the end of the cup body 2; the middle frame assembly 20 is sleeved on the outside of the screw thread assembly 10 and can be fixedly or movably connected to the screw thread assembly 10; the cup cover 30 is covered on the middle frame assembly 20 and can be opened or closed relative to the middle frame assembly 20; the locking member 60 is disposed on the middle frame assembly 20, and the locking member 60 has a first state in which the middle frame assembly 20 is movably connected to the screw thread assembly 10, and a second state in which the middle frame assembly 20 is fixedly connected to the screw thread assembly 10; the first control assembly 40 is used to control the locking member 60 to movably connect the middle frame assembly 20 to the screw thread assembly 10; the second control assembly 50 is used to control the locking member 60 to fixally connect the middle frame assembly 20 to the screw thread assembly 10. The first control component 40 controls the locking component 60 to movably connect the middle frame assembly 20 and the threaded assembly 10, while the second control component 50 controls the locking component 60 to fix the middle frame assembly 20 and the threaded assembly 10. Specifically, the first control component 40 and the second control component 50 respectively control the locking component 60 to move away from or towards the threaded assembly 10. When the locking component 60 is away from the threaded assembly 10, the middle frame assembly 20 and the threaded assembly 10 are movably connected; when the locking component 60 is close to the threaded assembly 10, the middle frame assembly 20 and the threaded assembly 10 are fixedly connected. The use of the second control component 50 prevents the locking function from easily failing due to poor contact caused by the cup body 2 being placed on its side or friction from the connecting parts.

[0042] When the cup cover 30 is closed relative to the middle frame assembly 20, the first control component 40 applies a driving force to the locking member 60 to put the locking member 60 in a first state; when the cup cover 30 is open relative to the middle frame assembly 20, the second control component 50 applies a driving force to the locking member 60 to put the locking member 60 in a second state; when the screw thread assembly 10 and the middle frame assembly 20 are fixedly connected, when the middle frame assembly 20 is rotated relative to the cup body, the screw thread assembly 10 can rotate synchronously with the middle frame assembly 20, thereby disengaging the middle frame assembly 20 and the screw thread assembly 10 from the cup body 2; when the screw thread assembly 10 and the middle frame assembly 20 are movably connected, when the middle frame assembly 20 is rotated relative to the cup body 2, the screw thread assembly 10 does not rotate synchronously with the middle frame assembly 20, and the screw thread assembly 10 does not rotate relative to the cup body 2, thereby preventing the middle frame assembly 20 and the screw thread assembly 10 from disengaging from the cup body 2.

[0043] Optionally, when the locking member 60 is in the first state, the second control component 50 does not apply a driving force to the locking member 60. By using only the first control component 40 to control the locking member 60, and the second control component 50 not applying a driving force to the locking member 60, it is possible to ensure that the locking member 60 keeps the middle frame assembly 20 and the threaded assembly 10 in a movably connected state.

[0044] Optionally, when the locking member 60 is in the first state, the driving force applied by the first control component 40 is always greater than the driving force applied by the second control component 50; ensuring that the locking member 60 keeps the middle frame assembly 20 and the threaded assembly 10 in a movably connected state.

[0045] Optionally, when the locking member 60 is in the second state, the first control component 40 does not apply a driving force to the locking member 60, ensuring that the locking member 60 keeps the middle frame component 20 and the threaded component 10 in a fixed connected state.

[0046] Optionally, when the locking member 60 is in the second state, the driving force applied by the first control component 40 is always less than the driving force applied by the second control component 50; ensuring that the locking member 60 keeps the middle frame assembly 20 and the threaded assembly 10 in a fixed connected state.

[0047] Optionally, when the locking member 60 is in the second state, the driving force applied by the first control component 40 is always less than the resultant force of the driving force applied by the second control component 50 and gravity; ensuring that the locking member 60 keeps the middle frame component 20 and the threaded component 10 in a fixed connected state.

[0048] like Figure 6 As shown, optionally, the first control component 40 includes a first magnet 41, which is mounted on the cup cover 30; the locking member 60 is provided with a third magnet 63; when the cup cover 30 is closed, the first magnet 41 attracts the third magnet 63, causing the locking member 60 to move away from the screw thread assembly 10, thus movably connecting the middle frame assembly 20 with the screw thread assembly 10. Through the mutual attraction between the first magnet 41 and the third magnet 63, when the cup cover 30 is closed, the first magnet 41 always exerts an attraction on the third magnet 63, ensuring that the locking member 60 will not separate due to external shaking or collision, thus ensuring that the middle frame assembly 20 and the screw thread assembly 10 are always movably connected.

[0049] like Figure 6 As shown, optionally, the second control component 50 includes a second magnet 51, which is mounted on the middle frame component 20. When the cup cover 30 is closed, the magnetic force applied by the first magnet 41 to the third magnet 63 is greater than the magnetic force applied by the second magnet 51 to the third magnet 63, so that the locking member 60 is in the first state. When the cup cover 30 is opened, the first magnet 51 moves away from the third magnet 63 along with the cup cover, and the second magnet 41 attracts the third magnet 63, so that the locking member 60 switches from the first state to the second state. By utilizing the fact that the attraction force of the first magnet 41 to the third magnet 63 is greater than the attraction force of the second magnet 51 to the third magnet 63, it is ensured that after the cup cover 30 is closed, the threaded assembly 10 is movably connected to the middle frame component 20; at the same time, it is ensured that after the cup cover 30 is opened, the threaded assembly 10 is fixedly connected to the middle frame component 20.

[0050] Preferably, the first magnet 41 and the third magnet 63 are strong magnets, such as rubidium magnets; the second magnet 51 is a weak magnet, such as a ferrite magnet; and when the cup cover 30 is closed, the distance between the first magnet 41 and the third magnet 63 is closer than the distance between the second magnet 51 and the third magnet 63; at this time, the attraction of the first magnet 41 to the third magnet 63 is greater than the attraction of the second magnet 51 to the third magnet 63, thereby ensuring that when the cup cover 30 is closed, the screw thread assembly 10 is movably connected to the middle frame assembly 20; at the same time, when the cup cover 30 is opened, the first magnet 41 moves away from the third magnet 63, and the second magnet 51 can attract the third magnet 63 to move, so that the screw thread assembly 10 is fixedly connected to the middle frame assembly 20.

[0051] Preferably, the first magnet 41, the second magnet 51, and the third magnet 63 are all strong magnets or weak magnets, and when the cup cover 30 is closed, the distance between the first magnet 41 and the third magnet 63 is less than the distance between the second magnet 51 and the third magnet 63. At this time, the attraction of the first magnet 41 to the third magnet 63 is greater than the attraction of the second magnet 51 to the third magnet 63, thereby ensuring that when the cup cover 30 is closed, the screw thread assembly 10 is movably connected to the middle frame assembly 20. At the same time, when the cup cover 30 is opened, the first magnet 41 moves away from the third magnet 63, and the second magnet 51 can attract the third magnet 63 to move, so that the screw thread assembly 10 is fixedly connected to the middle frame assembly 20.

[0052] like Figure 4 and Figure 6 As shown, optionally, the locking member 60 includes a slider 61 and a locking tooth 62; the middle frame assembly 20 is provided with a sliding groove 21, and the slider 61 moves along the sliding groove 21 to allow the locking member 60 to move away from or towards the threaded assembly 10; the threaded assembly 10 is provided with a locking groove 11; when the slider 61 moves along the sliding groove 21 and approaches the threaded assembly 10, the locking tooth 62 moves into the locking groove 11, and the middle frame assembly 20 is fixedly connected to the threaded assembly 10 via the locking tooth 62 in the locking groove 11; when the slider 61 moves away from the threaded assembly 10 along the sliding groove 21, the locking tooth 62 moves out of the locking groove 11, and the middle frame assembly 20 is movably connected to the threaded assembly 10. The cooperation of the locking tooth 62 and the locking groove 11 enables the middle frame assembly 20 and the threaded assembly 10 to be quickly connected or separated, ensuring that the middle frame assembly 20 and the threaded assembly 10 can be quickly and movably connected or fixedly connected.

[0053] like Figure 1 As shown, optionally, there are multiple snap-fit ​​slots 11, arranged in a ring around the threaded assembly 10. When the snap-fit ​​teeth 62 rotate with the middle frame assembly 20 to any position, they can all be positioned within the corresponding snap-fit ​​slots 11 as the slider 61 moves toward the threaded assembly 10. The ring arrangement of the snap-fit ​​slots 11 eliminates concerns about the middle frame assembly 20 and the threaded assembly 10 failing to be securely connected in a timely manner after the cup cover 30 is opened, ensuring the timely and secure connection between the middle frame assembly 20 and the threaded assembly 10.

[0054] like Figures 2-3 as well as Figure 9 As shown, optionally, a detection mechanism 90 is also included. The detection mechanism 90 is located in the middle frame assembly 10 and is used to detect the temperature of the liquid inside the cup body 2. After the threaded assembly 10 is installed with the cup body 2, the detection mechanism 90 is directly connected to the liquid storage space 230 inside the cup body 2. By directly connecting the detection mechanism 90 to the liquid storage space 230 inside the cup body 2, when liquid is stored in the cup body 2, the detection mechanism 90 can directly contact the liquid inside the cup body 2, ensuring the accuracy of temperature measurement.

[0055] Optionally, the electronic component 130 is disposed within the middle frame component 20. By displacing the electronic component 130 within the middle frame component 20 after the middle frame component 20 is connected to the main body 2, the electronic component 130 does not shift relative to the main body 2. This means that the weight of the electronic component 130 is no longer concentrated on the cup lid, making the cup lid easier to open and convenient to use.

[0056] like Figures 2-3 As shown, optionally, the temperature sensor 91 includes a thermistor (not shown) and a temperature conductor 911. After the cup lid 1 and cup body 2 are installed, the temperature conductor 911 connects the liquid storage space 230 inside the cup body 2 and the thermistor to conduct the temperature of the liquid storage space 230 to the thermistor. Since the detection mechanism 90 can directly contact the liquid, using a thermistor and the temperature conductor 911 for detection ensures more accurate measurement.

[0057] like Figures 1-2 As shown, optionally, the threaded assembly 10 is a ring-shaped structure with both sides connected; the temperature sensor 91 is directly connected to the inside of the cup body 2 via the inner side of the ring. The ring-shaped design ensures that the threaded assembly 10 does not obstruct the contact between the temperature sensor 91 and the liquid inside the cup body 2.

[0058] like Figures 1-3 as well as Figures 6-7 As shown, optionally, the middle frame assembly 20 includes an inner middle frame sleeve 22 and an outer middle frame sleeve 23, with the threaded assembly 10 located between the inner middle frame sleeve 22 and the outer middle frame sleeve 23; the threaded assembly 10 has an annular protrusion 12 inside, and an annular groove 24 outside the inner middle frame sleeve 22; the middle frame assembly 20 is rotatably connected via the annular protrusion 12 and the annular groove 24. The temperature sensor 91 is located inside the inner middle frame sleeve 22. The threaded assembly 10 is positioned between the inner middle frame sleeve 22 and the outer middle frame sleeve 23 to prevent direct contact between the outside and the threaded assembly 10, thus preventing the cup lid 1 from being easily opened; the middle frame assembly 20 is rotatably connected to the threaded assembly 10 via the annular protrusion 12 and the annular groove 24 to prevent separation of the middle frame assembly 20 from the threaded assembly 10. The temperature sensor 91 is located inside the inner middle frame sleeve 22 to facilitate contact with the liquid inside the cup body 2.

[0059] Optionally, a sleeve is provided on the inner sleeve 22 of the middle frame, with the outer end of the sleeve placed outside the inner sleeve 22. When the inner sleeve 22 of the middle frame is installed with the cup body 2, the outer end of the sleeve is located inside the cup body 2, and the temperature sensor 91 is placed inside the sleeve. By placing the temperature sensor inside the sleeve and detecting the temperature inside the cup body 2 through the sleeve, the temperature sensor 91 is effectively protected.

[0060] Optionally, the sleeve is made of stainless steel, which allows for rapid heat conduction.

[0061] Optionally, the gap between the temperature sensor 91 and the sleeve is filled with thermally conductive silicone grease, so that the temperature sensor 91 can receive the thermal signal in a timely manner; at the same time, the thermally conductive silicone grease can also prevent the temperature sensor 91 from separating from the sleeve, which would lead to inaccurate detection.

[0062] Optionally, the inner sleeve 22 of the middle frame is provided with a through hole, through which the temperature sensor 91 protrudes from the inner sleeve 22 of the middle frame.

[0063] Optionally, a sealing layer is provided inside the through hole. The sealing layer is made of rubber to prevent liquid in the cup body 2 from entering the middle frame assembly 10 and causing the temperature sensor 91 to malfunction.

[0064] Optionally, the electronic component 130 further includes a PCB circuit board 110, which is used to output control signals. The PCB circuit board 110 enables signal reception and transmission.

[0065] Optionally, the electronic component 130 also includes a display 100; the display 100 is electrically connected to the PCB circuit board 110; the display 100 is used to display the temperature detected by the temperature sensor 91. By displaying the temperature using the display 100, the temperature of the liquid inside the cup 2 can be known in a timely manner, determining whether it is safe to drink and preventing burns caused by excessively high temperatures.

[0066] Optionally, the electronic component 130 also includes a switching mechanism 70 and a switching signal receiver 80 for triggering the switching mechanism 70; the switching mechanism 70 and the switching signal receiver 80 are disposed on the middle frame assembly 20; the switching signal receiver 80 is electrically connected to the PCB circuit board 110; when the switching signal receiver 80 triggers the switching mechanism 70, the cup cover 30 opens relative to the middle frame assembly 20. Triggering the switching mechanism 70 via the signal receiver 80 prevents the cup cover 30 from being opened by someone other than the person in question.

[0067] like Figure 4As shown, optionally, the switching mechanism 70 includes a motor 71, a slot 13, and a push rod 72. The motor 71 and push rod 72 are located in the middle frame assembly; the slot 13 is located in the cup cover 30. The motor 71 can push the push rod 72 to move, causing the push rod 72 to insert into or move out of the slot 13. When the motor 71 receives a trigger signal from the switch signal receiver, the motor 71 pushes the push rod 72 to move. After the cup cover is closed, the motor 71 pushes the push rod 72 into the slot 13, ensuring that the cup cover 30 is not opened.

[0068] Optionally, the cup cover 30 is rotatably connected to the middle frame assembly 20, and a torsion spring is installed at the rotatable connection. The torsion spring facilitates the cup cover 30 to spring away from the middle frame assembly 20 after it is opened.

[0069] like Figure 2 As shown, optionally, the switch signal receiver 80 can be a fingerprint controller, electronic password lock, or facial recognition device, etc., which can prevent the cup cover from being opened after the liquid containing device 2 is taken by others. When the cup cover cannot be opened, the locking member makes the screw thread assembly and the middle frame assembly movably connected. When the middle frame assembly is rotated relative to the cup body, that is, when an outsider rotates the cup lid 1, the screw thread assembly does not rotate synchronously with the middle frame assembly. The screw thread assembly does not rotate relative to the cup body. That is, at this time, the middle frame assembly is spinning freely. The middle frame assembly and the screw thread assembly cannot be detached from the cup body, that is, the cup lid cannot be opened. This invention can avoid the potential risks caused by others arbitrarily unscrewing the cup lid 1.

[0070] like Figures 3-4 As shown, optionally, the electronic component 130 also includes a battery 120, which powers the PCB circuit board 110. Power from the battery 120 ensures continuous operation of the PCB circuit board 110, thus guaranteeing the opening of the cup cover 30 and the display of the liquid temperature.

[0071] like Figures 8-11 As shown, this embodiment provides a liquid containing device, which includes a cup body 2 and a cup lid 1. The cup body 2 has an opening at its end; the cup lid 1 is installed at the opening at the end of the cup body 2.

[0072] like Figures 10-11 As shown, in this embodiment, the liquid containing device also includes a base and a straw 220. The base is glued or snapped to the other end of the cup body 2. The straw 220 is placed inside the cup body 2, and a mouthpiece is provided in the middle of the middle frame assembly 20. One end of the straw 220 near the spiral tooth assembly 10 is placed inside the mouthpiece, and the other end of the straw 220 is placed at the bottom of the cup body 2.

[0073] like Figures 10-11 As shown, optionally, a rubber ring 210 is installed at the opening position inside the cup body 2. When the cup lid 1 is installed with the cup body 2, the inner sleeve 22 of the middle frame assembly 20 squeezes the rubber ring 210 to ensure that the combination of the cup lid 1 and the cup body 2 can prevent water from spilling.

[0074] Optionally, the threaded assembly 10 is provided with an internal thread, and the cup body 2 is provided with an external thread. The threaded assembly 10 and the cup body 2 are installed by rotating the threaded assembly.

[0075] In summary, this utility model provides a cup lid and a liquid containing device. By setting the detection mechanism in the middle frame assembly, the temperature of the liquid inside the cup can be accurately detected. Furthermore, by setting all electronic components in the middle frame assembly, the cup lid no longer bears the weight of the electronic components, making it easier to open the cup lid.

[0076] 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 of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
