[0065] Please refer to the attached Figures 1 to 3 , Figure 1 FIG. 3 is a front view of the Hall sensor 30 in the water cup of the present invention. Figure 2 FIG. 1 is an exploded view of the Hall sensor 30 in the water cup of the present invention. Figure 3: is a cross-sectional view of the Hall sensor 30 in the water cup of the present invention. The embodiment of the present invention provides a water volume detection device, including one of a capacitive sensor, a photoelectric sensor, a Hall sensor 30, and a pressure sensor, wherein the Hall sensor 30 includes: a housing 31, a rotor assembly 33, and a first Hall switch 34, a cavity is provided in the housing 31, a water inlet 313 and a water outlet 314 connected to the cavity are provided on the housing 31, the rotor assembly 33 is rotatably mounted in the cavity, the liquid entering the cavity through the water inlet 313 flows out from the water outlet 314 after driving the rotor assembly 33 to rotate, and the first Hall switch 34 is used to sense the magnetic field changes generated when the rotor assembly 33 rotates.

[0066] It should be explained that in some embodiments, the first Hall switch 34 can be installed on the shell 31, and in other embodiments, the first Hall switch 34 can also be installed on the equipment to which the water level detection device in this embodiment is applied. However, no matter which installation method is used, it is necessary to ensure that the first Hall switch 34 is relatively fixed to the shell 31 to ensure that the first Hall switch 34 is in a relatively stable position to sense the magnetic field changes generated when the rotor assembly 33 rotates.

[0067] It should be explained that the water volume detection device includes one of a capacitive sensor, a photoelectric sensor, a Hall sensor 30, and a pressure sensor. Among them, the water volume detection device proposed in this embodiment includes a Hall sensor, which will be described in detail later and will not be repeated here. Among them, the water volume detection device proposed in this embodiment may also include a pressure sensor for sensing the weight of the liquid in the cavity 11, and obtaining the flow rate data of the liquid outflowing from the cavity 11 and / or the drinking water information determined based on the flow data by comparing the change value of the liquid weight. Among them, the water volume detection device proposed in this embodiment may also include a photoelectric sensor, which uses laser ranging to measure the liquid level height, and obtains the flow rate data of the liquid outflowing from the cavity 11 and / or the drinking water information determined based on the flow data by comparing the change value of the liquid level height.

[0068] It is understandable that, in practical applications, the rotor assembly 33 in this embodiment needs to be installed on the flow path of the liquid circuit that needs to measure the flow, so that the liquid in the liquid circuit enters the cavity in the housing 31 from the water inlet 313, and drives the rotor assembly 33 to rotate a certain angle in the cavity and then flows out from the water outlet 314. In this process, the rotation of the rotor assembly 33 will produce a change in the magnetic field, and the first Hall switch 34 will sense this change in the magnetic field and generate an electrical signal corresponding to this change in the magnetic field. Therefore, by sensing the electrical signal generated by the first Hall switch 34, the number of rotations of the rotor assembly 33 per unit time can be analyzed, and the flow data flowing through the rotor assembly 33 can be further calculated and analyzed. Specifically, the present application is designed based on the Hall effect and fluid dynamics. In the present device, the first Hall switch 34 is used as a sensor to sense the changes in the magnetic field generated when the rotor assembly 33 rotates. The rotor assembly 33 itself is magnetic or has a magnetic material connected to it. When the rotor assembly 33 rotates, its magnetic field will change and then be sensed by the first Hall switch 34. At the same time, in the present device, the rotor assembly 33 can rotate under the action of liquid flow, and the number of rotations is proportional to the flow rate of the liquid. Therefore, by measuring the number of rotations of the rotor assembly 33 per unit time, the flow data of the liquid can be indirectly obtained.

[0069] In some embodiments, the Hall sensor 30 in this embodiment is applied to a water cup to measure the amount of water a user drinks when using the water cup, thereby solving the problem that existing water cup products lack a water amount detection function, allowing users to more effectively monitor and manage their personal water intake. In other embodiments, in addition to being applied to water cups, the Hall sensor 30 in this embodiment can also be widely used in other occasions that require liquid flow measurement, such as water dispensers, water purifiers, kettles, etc.

[0070] For further information, see Figure 4 and Figure 5 , Figure 4 Schematic diagram of the first internal structure of the Hall sensor 30 in the water cup of the present invention, Figure 5The second internal structure schematic diagram of the Hall sensor 30 in the water cup of the present invention. The housing 31 of the present embodiment includes an upper housing 311 and a lower housing 312, a water outlet 314 is provided in the upper housing 311, and a water inlet 313 is provided in the lower housing 312; a slot body 32 is provided on the side of the upper housing 311 facing the lower housing 312 or the side of the lower housing 312 facing the upper housing 311, the slot body 32 includes a first area 321, a second area 322 and a third area 323, a rotor assembly 33 is rotatably provided in the first area 321, the water inlet 313 is connected to the second area 322, and the water outlet 314 is connected to the third area 323; the liquid entering from the water inlet 313 first flows into the second area 322, and then flows into the first area 321 to drive the rotor assembly 33 of the first area 321 to rotate, and finally flows into the third area 323 and flows out through the water outlet 314.

[0071] It can be understood that the trough body 32 in this embodiment is used to form the above-mentioned cavity together with the upper shell 311 and the lower shell 312. It should be noted that when the upper shell 311 and the lower shell 312 are installed in place, the cavity formed by the trough body 32 and the upper shell 311 and the lower shell 312 is a closed chamber with only two openings, the water inlet 313 and the water outlet 314. Furthermore, the first area 321 is used to install the rotor assembly 33 and connect the second area 322 and the third area 323. The second area 322 is used to connect the water inlet 313 and guide the liquid entering from the water inlet 313 to the first area 321. The third area 323 is used to connect the water outlet 314 and guide the liquid flowing into from the first area 321 to the water outlet 314. Through the above-mentioned first area 321, second area 322, and third area 323, the liquid entering the cavity from the water inlet 313 can flow according to a preset trajectory and then flow out from the water outlet 314. The preset trajectory enables the liquid entering the cavity from the water inlet 313 to pass through the rotor assembly 33, so that the flow measurement result of the Hall sensor 30 of this embodiment is more accurate.

[0072] Furthermore, the upper shell 311 and the lower shell 312 are detachably installed. When the upper shell 311 and the lower shell 312 are installed in place, the projection of the water inlet 313 onto the tank body 32 is located in the second area 322, and the projection of the water outlet 314 onto the tank body 32 is located in the third area 323. It should be explained that the installation of the upper shell 311 and the lower shell 312 described herein refers to the state after the upper shell 311 and the lower shell 312 are fully connected in a preset connection manner, which means that it is only necessary to fully connect the upper shell 311 and the lower shell 312 in a preset connection manner, and the projections of the water inlet 313 and the water outlet 314 onto the tank body 32 will be located in the second area 322 and the third area 323, without the need to manually align the water inlet 313 with the second area 322 or the water outlet 314 with the third area 323 when the upper shell 311 and the lower shell 312 are assembled, thereby simplifying the assembly process of the Hall sensor 30 and improving assembly efficiency and accuracy. Optionally, the above-mentioned preset connection mode may be a snap connection or a threaded connection, that is, the upper shell 311 and the lower shell 312 are snap-connected or threadedly connected.

[0073] In some embodiments, the upper shell 311 is connected with the lower shell 312 by snapping. Specifically, the outer peripheral side of the upper shell 311 is provided with a plurality of rotatable snap heads, and the lengths of the plurality of snap heads are different, so that the lowest points of the rotating distal end on the rotating trajectory are also different; the outer peripheral side of the lower shell 312 is provided with a plurality of snap grooves of different heights, and the snap grooves of different heights correspond to the snap heads of different lengths one by one. Therefore, when assembling the upper shell 311 and the lower shell 312, the upper shell 311 and the lower shell 312 are installed in place only when and only when each snap joint is snapped into the corresponding snap groove, and at this time, the projections of the water inlet 313 on the lower shell 312 and the water outlet 314 on the upper shell 311 onto the tank body 32 are exactly located in the second area 322 and the third area 323.

[0074] In some embodiments, Figure 2 and Figure 3As shown, the upper shell 311 is threadedly connected with the lower shell 312. Specifically, an outer rib 3111 is spirally provided on the outer circumference of the upper shell 311, and an inner rib 3121 is spirally provided on the inner circumference of the lower shell 312, an outer groove is formed between the outer rib 3111 and the outer circumference of the upper shell 311, and an inner groove is formed between the inner rib 3121 and the inner circumference of the lower shell 312; wherein, the outer rib 3111 is rotatably matched with the inner groove, and the inner rib 3121 is rotatably matched with the outer groove, and an inner stopper is provided at the end of the inner groove relative to the screw-in direction of the outer rib 3111, and the inner stopper is used to limit the screw-in distance of the outer rib 3111 screwed into the inner groove, and / or, an outer stopper 3112 is provided at the end of the outer groove relative to the screw-in direction of the inner rib 3121, and the outer stopper 3112 is used to limit the screw-in distance of the inner rib 3121 screwed into the outer groove. Thus, when assembling the upper shell 311 and the lower shell 312, when the outer rib 3111 is screwed into the inner groove until it abuts against the inner stop block, and / or when the inner rib 3121 is screwed into the outer groove until it abuts against the outer stop block 3112, the upper shell 311 and the lower shell 312 are installed in place. At this time, the projections of the water inlet 313 on the lower shell 312 and the water outlet 314 on the upper shell 311 onto the trough body 32 are exactly located in the second area 322 and the third area 323.

[0075] Further, such as Figure 5 As shown, in order to ensure that the rotor assembly 33 in the Hall sensor 30 can be stably and correctly installed and effectively cooperate with the flowing liquid, thereby achieving accurate flow measurement, a first mounting portion 3211 is provided in the first area 321 of this embodiment, and the rotor assembly 33 is provided with a second mounting portion 334; when the first side 35 of the rotor assembly 33 is installed toward the slot body 32, the second mounting portion 334 accommodates the first mounting portion 3211; when the second side 36 of the rotor assembly 33 is installed toward the slot body 32, the first mounting portion 3211 abuts against the second mounting portion 334. Optionally, the second side 36 and the first side 35 are opposite sides of the rotor assembly 33.

[0076] It should be explained that the rotation direction of the rotor assembly 33 in the first area 321 is fixed. Therefore, the rotor assembly 33 needs to be installed in the first area 321 according to a preset posture to ensure stable cooperation with the flowing liquid. For example, the rotor assembly 33 is required to be installed with the first side 35 facing the groove body 32 during the design stage. Then the rotor assembly 33 should have the function of adapting only when and only when its first side 35 is installed toward the groove body 32, so as to prevent the user from installing it upside down, resulting in unstable operation or malfunction of the Hall sensor 30. In this embodiment, through the matching relationship between the first mounting portion 3211 and the second mounting portion 334, when the first side surface 35 of the rotor assembly 33 is installed toward the slot body 32, the second mounting portion 334 will accommodate the first mounting portion 3211 to achieve correct installation and matching; when the second side surface 36 of the rotor assembly 33 is installed toward the slot body 32 (i.e., installed upside down), the first mounting portion 3211 will resist the second mounting portion 334, preventing the rotor assembly 33 from continuing to be installed. If the upper shell 311 and the lower shell 312 continue to be installed, they will not be able to be installed in place, thereby avoiding incorrect installation.

[0077] For further information, see Figures 5 to 8 , Figure 6 This is a three-dimensional view of the first side 35 of the rotor assembly 33 in the water cup of the present invention. Figure 7 is a cross-sectional view of the rotor assembly 33 in the water cup of the present invention, Figure 8 3 is a cross-sectional view of the upper shell 311 of the water cup of the present invention. In this embodiment, the first mounting portion 3211 includes a first protrusion 32111 disposed in the first area 321 and a positioning shaft 32112 disposed on the first protrusion 32111, and the second mounting portion 334 includes an avoidance groove 3341 disposed on the first side 35 of the rotor assembly 33, a second protrusion 3342 disposed on the second side 36 of the rotor assembly 33, and a positioning hole 3343 penetrating the avoidance groove 3341 and the second protrusion 3342; when the first side 35 of the rotor assembly 33 is mounted toward the slot body 32, the positioning shaft 32112 is inserted into the positioning hole 3343, and the first protrusion 32111 is accommodated in the avoidance groove 3341; when the second side 36 of the rotor assembly 33 is mounted toward the slot body 32, the positioning shaft 32112 is inserted into the positioning hole 3343, and the first protrusion 32111 is pressed against the second protrusion 3342.

[0078] It is understandable that if Fig. 9 and Fig.10 As shown, Fig. 9 This is a cross-sectional view of the first side surface 35 of the rotor assembly 33 in the water cup of the present invention when it is installed toward the groove body 32. Fig.10It is a cross-sectional view of the rotor assembly 33 in the water cup of the present invention when the second side 36 is installed toward the slot body 32. In this embodiment, the cooperation between the positioning shaft 32112 and the positioning hole 3343 is to provide a rotation pair for the rotor assembly 33, so that the rotor assembly 33 can stably rotate in the first area 321. The first protrusion 32111 is arranged in the second area 322, and the avoidance groove 3341 is arranged on the first side 35 of the rotor assembly 33. When the first side 35 of the rotor assembly 33 is installed toward the slot body 32, the first protrusion 32111 can be smoothly accommodated in the avoidance groove 3341, and the positioning shaft 32112 is also inserted into the positioning hole 3343, and the rotor assembly 33 is stably installed in the first area 321. When the second side surface 36 of the rotor assembly 33 is installed toward the slot body 32, although the positioning shaft 32112 can still be inserted into the positioning hole 3343, the first protrusion 32111 will press against the second protrusion 3342, preventing the rotor assembly 33 from continuing to be installed to the correct position. Specifically, the rotor assembly 33 will exceed the height H of the second area 321. If the upper shell 311 and the lower shell 312 continue to be installed, they will not be able to be installed in place, preventing the user from incorrectly installing the rotor assembly 33. At this time, the user should be aware of the wrong installation direction and readjust the installation posture of the rotor assembly 33.

[0079] For further information, see Fig.11 , Fig.11 FIG. 3 is an exploded view of the rotor assembly 33 in the water cup of the present invention. In this embodiment, the rotor assembly 33 includes: a rotor body 331 , at least two first magnets 332 disposed in the rotor body 331 , and a plurality of blades 333 extending outward from the outer peripheral side of the rotor body 331 .

[0080] In this embodiment, the rotor body 331 is the main structure of the rotor assembly 33, responsible for supporting and fixing the first magnet 332 and the blade 333, the first magnet 332 is used to generate a magnetic field and interact with the first Hall switch 34, and the blade 333 is used to capture the kinetic energy of the fluid flow and convert it into the rotational kinetic energy of the rotor. Optionally, the number of the first magnets 332 can be two, and the two first magnets 332 are arranged diagonally about the rotation center axis of the rotor body 331, and the polarities are opposite. Optionally, four first magnets 332 are arranged in the rotor body 331, and the four first magnets 332 are evenly arranged around the rotation center axis of the rotor body 331, and the polarities are alternated, and the polarity arrangement is SNSN. Optionally, the rotor body 331 is provided with an open mounting groove 3311 for placing the first magnet 332, and a notch cover 335 is provided at the notch of the open mounting groove 3311. Optionally, the rotor body 331 is provided with twelve blades 333, and the twelve blades 333 are evenly arranged around the rotation center axis of the rotor body 331. It can be understood that when the liquid passes through the Hall sensor 30, the impact force of the liquid on the blade 333 will cause the rotor assembly 33 to start rotating. As the rotor assembly 33 rotates, the first magnet 332 also rotates. The magnetic field generated by the first magnet 332 interacts with the first Hall switch 34, and the first Hall switch 34 generates a corresponding electrical signal. The frequency of this electrical signal is proportional to the rotation speed of the rotor, thereby indirectly measuring the flow data of the fluid and / or the drinking water information determined based on the flow data.

[0081] Specifically, the blades 333 are bent along the rotation direction of the rotor body 331. This embodiment aims to reduce the resistance of the fluid on the blades 333 by bending the blades 333 along the rotation direction of the rotor body 331, while increasing the ability of the blades 333 to capture the kinetic energy of the fluid, thereby improving the rotation efficiency of the rotor assembly 33 and the accuracy of flow measurement. The blades 333 are bent along the rotation direction of the rotor body 331, so that the fluid can change direction more smoothly when passing through the blades 333, reducing the resistance caused by the sudden change of the fluid direction.

[0082] Optionally, the diameter of the extended starting surface of the blade 333 is 9 mm to 11 mm. In the Hall sensor 30, this diameter determines the size of the connection area between the blade 333 and the rotor body 331, affects the firmness of the blade 333 and the distribution of the impact force of the fluid on the blade 333, and the diameter range of 9 mm to 11 mm is selected to reduce the resistance of the fluid when passing through while ensuring sufficient connection strength, thereby improving the accuracy of measurement.

[0083] Optionally, each blade 333 is bent in the same direction as the rotation direction of the rotor body 331, and the bending radius of the blade 333 on both sides of the rotation direction of the rotor assembly 33 is 5.5mm-5.9mm and 6.0mm-6.4mm respectively. When the rotor body 331 rotates, the bending radius of the blade 333 affects the path and velocity distribution of the fluid flow, thereby affecting the sensitivity of the measurement. In this embodiment, these two specific bending radius ranges are selected to adjust the flow state of the fluid between the blades 333, reduce eddy currents and turbulence, and improve the stability and accuracy of the measurement.

[0084] Optionally, the thickness of the blade 333 in the rotation direction of the rotor body 331 is 0.5mm-0.7mm. Preferably, the thickness of the blade 333 in the rotation direction of the rotor body 331 is 0.6mm. The thickness of the blade 333 affects the overall weight, moment of inertia and resistance of the fluid passing through the rotor assembly 33. A thinner blade 333 can reduce the moment of inertia and improve the response speed, but too thin a blade 333 may cause insufficient strength of the blade 333 and easy damage. The present embodiment selects a thickness range of 0.5mm-0.7mm in order to reduce fluid resistance and improve the sensitivity and accuracy of the measurement while ensuring the strength of the blade 333.

[0085] Optionally, the distance from the distal end of the blade 333 to the rotation center axis of the rotor body 331 is 7mm-9mm. Preferably, the distance from the distal end of the blade 333 to the rotation center axis of the rotor body 331 is 8mm. The distance from the distal end of the blade 333 to the rotation center axis of the rotor body 331 determines the effective action area of ​​the blade 333 in the fluid, thereby affecting the flow range and sensitivity of the measurement. A larger distance can increase the force of the blade 333 on the fluid and improve the accuracy of the measurement, but it will also increase the moment of inertia of the rotor assembly 33 and the required power. In this embodiment, the distance range of 7mm-9mm is selected to find a balance between the measurement range and the response speed.

[0086] Optionally, the distance from the outer peripheral side of the rotor body 331 to the rotation center axis of the rotor body 331 is 4mm-6mm. Preferably, the distance from the outer peripheral side of the rotor body 331 to the rotation center axis of the rotor body 331 is 5mm. The distance from the outer peripheral side of the rotor body 331 to the rotation center axis of the rotor body 331 determines the overall size and compactness of the rotor assembly 33, and also affects the flow state of the fluid when passing through the rotor assembly 33. A smaller distance can reduce the volume and weight of the device and improve the portability and flexibility of the measurement, but it may also limit the amount of fluid passing through and the measurement range. In this embodiment, the distance range of 4mm-6mm is selected to strike a balance between the device size, the measurement range and the fluid permeability.

[0087] See also Figures 12 to 15 , Fig.12 This is a first stereoscopic view of the water cup of the present invention. Fig.13 This is a second stereoscopic view of the water cup of the present invention. Fig.14 This is an exploded view of the water cup of the present invention. Fig.15 for Fig.14 The present invention also provides a water cup, comprising the above water volume detection device, and further comprising: a cup body 10, comprising a cup mouth and provided with a cavity 11; a cup cover 20, which is provided on the cup mouth; a suction nozzle 21, which is provided on the cup cover 20 and connected to the cavity 11; the water volume detection device is used to measure the flow data of the liquid flowing out of the cavity 11 and / or the drinking water information determined based on the flow data.

[0088] In the water cup proposed in this embodiment, when the user uses the suction nozzle 21 to suck water, the liquid in the cavity 11 in the cup body 10 will be sucked out by the user after passing through the Hall sensor 30 due to the suction force of the user. This part of the liquid flowing through the Hall sensor 30 represents the amount of water drunk by the user. The Hall sensor 30 can obtain the amount of water drunk by the user by measuring the flow data of this part of the liquid.

[0089] In some embodiments, the water cup in this embodiment further includes a wireless connection module and an instruction execution module. The wireless connection module is used to connect to an external smart device. The external smart device is installed with an APP for controlling the water cup. The APP is used to receive user instructions and send execution instructions to the water cup according to the user instructions. The instruction module is used to respond according to the execution instructions and feed back the status information of the water cup to the APP for display. Therefore, the water cup in this embodiment can transmit the measured water intake data to the smart device to help users better monitor and manage their personal water intake.

[0090] For further information, see Figures 16 to 18 As shown, Fig.16 Schematic diagram of the structure of the cup cover 20 in the water cup of the present invention. Fig.17 This is an exploded view of the cup cover 20 in the water cup of the present invention. Fig.18Schematic diagram of the handle 23 structure of the water cup of the present invention. The water cup in this embodiment also includes a display device 22, and the display device 22 and the water volume detection device are both electrically connected to the control mainboard 24, and the control mainboard 24 is used to control the display device 22 to display the flow data measured by the water volume detection device and / or the drinking water information determined based on the flow data. It should be explained that the flow data mentioned in this embodiment refers to the flow rate of the liquid flowing out of the cavity 11 to the suction nozzle 21, and the drinking water information mentioned in this embodiment refers to the data that can be obtained by further calculating the flow data to indicate the user's drinking behavior. For example, the drinking water information in some embodiments may include the drinking water volume, which is used to indicate how much water the user has drunk through the water cup; the drinking water information in some embodiments may also include the drinking water progress, which is used to indicate the completion status of the user's distance from the set drinking water volume target. It can be understood that the display device 22 can be used to display various drinking water information about the flow data through artificial settings, and the above is only a limited example.

[0091] It should be explained that the amount of water consumed is the most direct drinking information, which indicates the amount of liquid actually consumed by the user through the water cup. The calculation method is to accumulate the flow data measured by the Hall sensor 30 within a period of time (such as each drinking process) to obtain the total amount of water consumed. For example, if the Hall sensor 30 measures a flow rate of 100 ml in 1 minute, then the amount of water consumed by the user in this 1 minute is 100 ml. When the drinking progress is used to indicate the completion of the user's set drinking target, first a target drinking amount (such as 2000 ml per day) needs to be set, and then the amount of water consumed (i.e., drinking amount) is calculated in real time or regularly, and the amount of water consumed is divided by the target drinking amount, and then multiplied by 100% to obtain the percentage of the drinking progress. For example, if the target drinking amount is 2000 ml and the current amount of water consumed is 1000 ml, then the drinking progress is 50%. Optionally, the display device 22 can be set on the cup cover 20 and / or the cup body 10. Optionally, the cup cover 20 is provided with a handle 23, and the display device 22 is provided on the handle 23. Optionally, the cup body 10 is provided with a base 13, and the display device 22 is provided on the base 13.

[0092] Preferably, in this embodiment, the display device 22 is arranged on the handle 23 of the cup cover 20. It can be understood that the display device 22 is arranged on the handle 23 of the cup cover 20, which not only avoids the position conflict with the suction nozzle 21, but also makes full use of the idle space of the handle 23. This layout reduces the increase in the overall size of the water cup and improves the volume utilization of the water cup. When the user holds the water cup, he can naturally see the data on the display device 22 on the handle 23, so as to understand his drinking amount.

[0093] In some embodiments, the handle 23 is a "U"-shaped structure with both ends connected to the cup cover 20, which is more in line with the natural curvature of the human hand, so that the user can more easily share the hand pressure when holding the water cup and reduce hand fatigue. Optionally, the handle 23 in other embodiments can also be a "concave" structure, or directly a strip structure.

[0094] Specifically, the handle 23 includes a bottom shell 231 and a cover plate 232. The bottom shell 231 is provided with a mounting groove 2311. The display device 22 is installed in the mounting groove 2311. The cover plate 232 is covered on the mounting groove 2311. Preferably, the handle 23 is a "U"-shaped structure with both ends connected to the cup cover 20, and the mounting groove 2311 is also "U"-shaped. It can be understood that the handle 23 is designed as a modular structure composed of the bottom shell 231 and the cover plate 232, which is convenient for the installation and maintenance of the display device 22. The mounting groove 2311 on the bottom shell 231 provides a special installation space for the display device 22, and the cover plate 232 is used to close the mounting groove 2311 to protect the display device 22 from interference from the external environment. Further, the mounting groove 2311 matches the "U"-shaped appearance of the handle 23, which not only enhances the structural stability of the handle 23, but also makes the installation of the display device 22 in the handle 23 more secure and not easy to loosen or damage. Preferably, the cover plate 232 is made of a transparent material that allows light to pass through. The cover plate 232 made of a transparent material enables the user to directly observe the display content of the display device 22 .

[0095] In some embodiments, see Figures 17 to 20 , Fig.19 is a schematic diagram of the structure of the lighting assembly 221 in the water cup of the present invention, Fig. 20 The exploded diagram of the light assembly 221 in the water cup of the present invention. The display device 22 includes a light assembly 221, and the light assembly 221 includes a light board 2211 and a plurality of lamp beads 2212 arranged on the light board 2211. The light board 2211 is arranged in the mounting groove 2311, and the plurality of lamp beads 2212 are arranged at intervals on the light board 2211. The light board 2211 is electrically connected to the control main board 24, and the control main board 24 is used to control the light assembly 221 to form lights of different visuals through the lamp beads 2212 to indicate flow data and / or drinking water information determined based on flow data. It can be understood that the light assembly 221 is used to form lights of different visuals to indicate flow data and / or drinking water information determined based on flow data, wherein the lights of different visuals formed by the light assembly 221 can be a light progress bar formed by controlling the light on and off, which is used to indicate the completion status of the user's distance from the set drinking water target. Alternatively, the lights of different visuals formed by the light assembly 221 can also be light prompts formed by controlling the light color, which are used to indicate whether the user's drinking water volume meets the standard.

[0096] Optionally, the light assembly 221 forms lights of different visuals by turning on and off the lamp beads 2212 to indicate the drinking water information determined based on the flow data. Specifically, the drinking water information in this embodiment refers to the completion status of the user's set drinking water target. For example, the light board 2211 is provided with ten lamp beads 2212 placed at equal distances, and the ten lamp beads 2212 represent the drinking water target set by the user. If one of the ten lamp beads 2212 is on and nine are off, it means that the user has completed one tenth of the set drinking water target. If two of the ten lamp beads 2212 are on and eight are off, it means that the user has completed two tenths of the set drinking water target, and so on.

[0097] Optionally, the light assembly 221 forms different visual lights through the light beads 2212 to indicate the drinking information determined based on the flow data. Specifically, the drinking information in this embodiment refers to the completion of the user's set single drinking target. For example, if the user's single drinking target is set to 100ML-200ML, if the light assembly 221 emits a red light, it means that the user's drinking amount is less than 100ML or greater than 200ML; if the light assembly 221 emits a green light, it means that the user's drinking amount is 100ML-200ML. Preferably, the light assembly 221 can also indicate the user's drinking information by controlling the flashing frequency of the light. For example, when the user's drinking amount is less than 100ML, the light assembly 221 emits a slowly flashing red light; when the user's drinking amount is greater than 200ML, the light assembly 221 emits a rapidly flashing red light. Optionally, the difference between slow flashing and fast flashing is the flashing frequency of the light. Optionally, the slow flashing can be 55 to 65 times per minute, and optionally, the fast flashing can be 80 to 120 times per minute.

[0098] Further, such as Fig. 22 and Fig.23 As shown, Fig. 22 This is a first cross-sectional view of the cup cover 20 of the water cup of the present invention. Fig.23 for Fig. 22In the present embodiment, the light assembly 221 further comprises a light shielding bracket 2213 and a light guide bar 2214. The light shielding bracket 2213 is provided with a first opening and a second opening opposite to each other. The first opening of the light shielding bracket 2213 is provided on the outer periphery of the light board 2211, and the light guide bar 2214 covers the second opening of the light shielding bracket 2213. In the present embodiment, the first opening of the light shielding bracket 2213 is provided on the outer periphery of the light board 2211 to limit the direct leakage of light and avoid glare or light pollution. The second opening allows the light to be diffused and distributed through the light guide bar 2214. The light guide bar 2214 can guide the light to propagate along a predetermined path, thereby achieving uniform distribution and a soft effect of the light. Optionally, the shading bracket 2213 is connected to the light board 2211 via a fixing structure (such as screws, clips, etc.) to ensure the overall stability of the lighting assembly 221, and the light guide strip 2214 is connected to the shading bracket 2213 via a suitable fixing method (such as glue, clips, etc.) to prevent loosening or falling off during use.

[0099] In some embodiments, Fig.17 As shown, the display device 22 includes a display screen assembly 222, the screen of the display screen assembly 222 faces the cover plate 232, and the display screen assembly 222 is electrically connected to the control mainboard 24, and the control mainboard 24 is used to control the display screen assembly 222 to display the flow data and / or the drinking water information determined based on the flow data through the screen. Optionally, the display screen assembly 222 can be a digital display screen or a liquid crystal display screen. Preferably, the control mainboard 24 is used to control the display screen assembly 222 to display the drinking water information determined based on the flow data through the screen. Specifically, the drinking water information in this embodiment refers to the amount of water the user drinks. For example, if the user drinks 100ML of water using the water cup, the words "100ML" will be displayed on the screen of the display screen assembly 222.

[0100] It should be explained that the display screen assembly 222, especially the liquid crystal display screen or the digital display screen, usually has a certain rigidity and is not easy to bend. If you try to bend it to adapt to the curved area 23112 of the mounting groove 2311, you may face technical challenges, such as screen damage, uneven display and other problems; at the same time, the manufacturing process of the curved display screen is relatively complicated, requiring high-precision processing and assembly technology, which will increase the production difficulty and manufacturing cost. Based on this, in this embodiment, the display screen assembly 222 is set in the straight area 23111, which reduces the production difficulty and cost and avoids display problems or user operation inconvenience caused by bending.

[0101] In some embodiments, the display device 22 includes both a light assembly 221 and a display assembly 222, the mounting groove 2311 includes a straight area 23111 and a curved area 23112, the display assembly 222 is disposed in the straight area 23111 and electrically connected to the control mainboard 24, and the light assembly 221 is disposed in the curved area 23112 and / or the straight area 23111 not blocked by the display assembly 222 and electrically connected to the control mainboard 24. In this embodiment, the display assembly 222 and the light assembly 221 are combined to provide more abundant water drinking reminders and status indications, the display assembly 222 presents the water drinking information in the form of numbers and graphics, making the information more intuitive and easy to understand, and the flashing or color change of the light assembly 221 can also provide intuitive visual prompts.

[0102] In some embodiments, the mounting groove 2311 on the handle 23 only includes a straight area 23111, and the display screen assembly 222 and the light assembly 221 are installed in different positions of the straight area 23111, that is, the light assembly 221 is arranged in the straight area 23111 that is not blocked by the display screen assembly 222.

[0103] Further, the water cup in this embodiment also includes a temperature measuring device, which is used to measure the liquid temperature of the liquid in the cavity 11, and the display device 22 includes a light component 221 and / or a display screen component 222, the light component 221 is used to form lights of different colors to indicate the liquid temperature, and the display screen component 222 is used to display the liquid temperature through the screen. It should be explained that the screen of the display screen component 222 can be divided into partitions, which are used to display the user's drinking water information and the liquid temperature respectively. Optionally, the temperature measuring device includes a temperature sensor, and the temperature sensor is electrically connected to the control mainboard 24. It can be understood that the temperature measuring device measures the temperature of the liquid in the cavity 11 in real time through the temperature sensor, and converts the temperature data into an electrical signal and transmits it to the control mainboard 24. The control mainboard 24 receives the electrical signal from the temperature sensor, and sends it to the display device 22 after processing and analysis, and the display device 22 displays according to the data sent by the control mainboard 24.

[0104] Further, such as Fig.24 As shown, Fig.24It is a second cross-sectional view of the cup cover 20 in the water cup of the present invention. The water cup in this embodiment also includes a sterilization device 25, which is used to perform a sterilization operation on the liquid in the cavity 11. Optionally, the sterilization device 25 in this embodiment includes an ultraviolet lamp, which is installed on the cup cover 20 and the light emission direction is downward. When the sterilization device 25 is working, the ultraviolet lamp lights up, and the ultraviolet light is irradiated into the cavity 11 to sterilize the liquid in the cavity 11. It can be understood that ultraviolet rays are an effective sterilization method that can destroy the DNA structure of bacteria and make them lose their reproductive ability, thereby achieving the purpose of sterilization. In this embodiment, the ultraviolet lamp is the core component of the sterilization device 25, and it irradiates the liquid in the cavity 11 by emitting ultraviolet light of a specific wavelength, thereby killing the bacteria therein. Optionally, the user can start the sterilization device 25 through a control button on the water cup or a smart device (such as a mobile phone APP).

[0105] Specifically, Fig.25 and Fig.26 As shown, Fig.25 This is a view showing the suction nozzle 21 of the water cup of the present invention rotated to the first position. Fig.26 This is a view of the suction nozzle 21 in the water cup of the present invention rotating to the second position. In this embodiment, the suction nozzle 21 includes a suction nozzle body and a drinking channel 211 penetrating the suction nozzle body; the suction nozzle body is rotatably arranged on the cup cover 20; when the suction nozzle body rotates to the first position, the drinking channel 211 is connected to the water quantity detection device 30, that is, the drinking channel 211 is connected to the cavity 11; when the suction nozzle body rotates to the second position, the drinking channel 211 cannot be connected to the water quantity detection device 30, that is, the drinking channel 211 cannot be connected to the cavity 11.

[0106] Specifically, the water cup in this embodiment further includes a control mainboard 24; the suction nozzle 21 is provided with a second magnet 27, and the control mainboard 24 is provided with a second Hall switch 26 inductively connected to the second magnet 27; when the suction nozzle 21 rotates to the first position, the second magnet 27 does not trigger the second Hall switch 26, and the control mainboard 24 controls the first Hall switch 34 to work; when the suction nozzle 21 rotates to the second position, the second magnet 27 triggers the second Hall switch 26, and the control mainboard 24 controls the first Hall switch 34 to sleep and / or power off. It should be explained that the water volume detection device includes the above-mentioned Hall sensor 30. When the suction nozzle 21 rotates to the first position, it means that the user may have a drinking behavior, and the Hall sensor 30 works, and the user's drinking volume is calculated by real-time monitoring of the flow rate during the user's drinking. When the suction nozzle 21 rotates to the second position, it means that the user will not have a drinking behavior, and the Hall sensor 30 sleeps and / or powers off, reducing unnecessary power consumption generated by the Hall sensor 30.

[0107] In one embodiment, the water volume detection device includes the above-mentioned pressure sensor. When the suction nozzle 21 rotates to the first position, it means that the user may have a drinking behavior. The pressure sensor works to monitor the weight change value of the liquid in the cavity 11 during the user's drinking period, and the user's drinking volume is calculated by the liquid weight change value. Optionally, the pressure sensor can measure the weight of the liquid in the cavity 11 once when the suction nozzle 21 rotates to the first position, and measure the weight of the liquid in the cavity 11 again when the suction nozzle 21 rotates to the second position. By comparing the difference in the weight of the liquid in the cavity 11 twice, the user's drinking volume can be obtained. Optionally, the pressure sensor can measure the weight of the liquid in the cavity 11 once each time the suction nozzle 21 rotates to the second position, and compare the liquid weight obtained by this measurement with the liquid weight obtained by the previous measurement to obtain the user's drinking volume. Optionally, in order to avoid inaccurate measurement results of the pressure sensor due to the water cup being placed non-horizontally, the pressure sensor can be configured to detect the current liquid weight once when a first condition and a second condition are met, the first condition being that the suction nozzle 21 rotates from the first position to the second position, and the second condition being that the water cup is placed horizontally for 10 seconds. The first condition is intended to reduce unnecessary working energy consumption of the pressure sensor, and the second condition is intended to avoid errors caused by detection when the water cup is in a non-horizontal state.

[0108] In one embodiment, the water volume detection device includes the above-mentioned photoelectric sensor, and the detection part of the above-mentioned water volume detection device is the photoelectric sensor. When the suction nozzle 21 rotates to the first position, it means that the user may have a drinking behavior. The photoelectric sensor works to monitor the change value of the liquid level height in the cavity 11 during the user's drinking, and the user's drinking volume is calculated by the change value of the liquid level height. Optionally, the photoelectric sensor can measure the liquid level height in the cavity 11 once when the suction nozzle 21 rotates to the first position, and measure the liquid level height in the cavity 11 again when the suction nozzle 21 rotates to the second position. By comparing the difference between the liquid level heights in the cavity 11 twice, the user's drinking volume can be obtained. Optionally, the photoelectric sensor can measure the liquid level height in the cavity 11 once each time the suction nozzle 21 rotates to the second position, and compare the liquid level height obtained by this measurement with the liquid level height obtained by the previous measurement, so as to obtain the user's drinking volume. Optionally, in order to avoid inaccurate measurement results of the photoelectric sensor due to the water cup being placed non-horizontally, the photoelectric sensor can be configured to detect the current liquid level height once when a first condition and a second condition are met, the first condition being that the suction nozzle 21 rotates from the first position to the second position, and the second condition being that the water cup is placed horizontally for 10 seconds. The first condition is intended to reduce unnecessary working energy consumption of the photoelectric sensor, and the second condition is intended to avoid errors caused by detection when the water cup is in a non-horizontal state.

[0109] Optionally, a nozzle cover 28 is further provided on the cup cover 20, and the nozzle cover 28 can be rotatably buckled on the cup cover 20, and an elastic member is provided between the nozzle 21 and the cup cover 20. When the user rotates to open the nozzle cover 28, the nozzle 21 will rotate and bounce to the first position under the action of the elastic member, and the second magnet 27 will move away from the second Hall switch 26, and the second Hall switch 26 will not be triggered, and the control main board 24 controls the power supply to supply power to the first Hall switch 34; when the user rotates the nozzle cover 28 to make it buckle on the cup cover 20, the nozzle 21 is pressed on the cup cover 20 to the second position by the pressure of the nozzle cover 28, and the second magnet 27 will move close to the second Hall switch 26, and the second Hall switch 26 will be triggered, and the control main board 24 controls the power supply to disconnect the power supply to the first Hall switch 34. It can be understood that the triggering state of the second magnet 27 to the second Hall switch 26 represents the user's drinking behavior, that is, when the second magnet 27 triggers the second Hall switch 26, it means that the user has lifted the suction nozzle 21 and is about to drink water; the initial state of the second magnet 27 to the second Hall switch 26 means that the user has buckled the suction nozzle 21 and the drinking behavior will not occur.

[0110] In this embodiment, the second Hall switch 26 is used to detect the position of the second magnet 27, and then determine whether the user is drinking water. By controlling the intelligent control logic on the main board 24, the intelligent management of the power supply to the first Hall switch 34 is realized. When the second Hall switch 26 detects the position change of the second magnet 27 and determines that the user is about to drink water, the main board 24 controls the power supply to the first Hall switch 34; when the user finishes drinking water and the second Hall switch 26 returns to the initial state, the main board 24 disconnects the power supply to the first Hall switch 34, and only supplies power to the first Hall switch 34 when the user actually drinks water, thereby improving the energy efficiency of the device and extending the service life of the device.

[0111] In some embodiments, Fig.12 and Fig.13 As shown, in order to make it more stable for the user to take and put the cup, a silicone sleeve 14 is provided on the cup body 10 to increase the friction when the user holds the cup, improve the holding stability, and reduce the risk of accidental falling.

[0112] In some embodiments, in order to ensure that the water cup can maintain good liquid circuit sealing during use and prevent liquid leakage, sealing rings are provided at the connection of each flow channel. The sealing rings are made of elastic material (such as rubber, silicone, etc.) and have good elasticity and recovery. When squeezed by external force, the sealing rings can undergo elastic deformation, fill and fit tightly in the gaps at the connection of the flow channels.

[0113] In some embodiments, Fig.21As shown, in order to make it easier for the user to suck out the liquid in the cavity 11 through the suction nozzle 21, the water cup of this embodiment also includes a straw 12. The straw 12 is connected to the water inlet 313 on the cup cover 20 and extends into the cavity 11, making it more convenient for the user to drink water.

[0114] In some embodiments, Fig.15 and Fig. 22 As shown, a battery 29 is provided in the cup cover 20, and the battery 29 is electrically connected to the control mainboard 24 to power the display device 22 and the water quantity detection device. Furthermore, a charging interface 241 is electrically connected to the control mainboard 24, and the insertion side of the charging interface 241 is exposed on the surface of the cup cover 20, so that the user can connect an external power source to the charging interface 241 through a charging cable to charge the battery 29 in the cup cover 20. Optionally, the charging interface 241 can be a Type-c interface, a Lightning interface, or a Microusb interface.
