[0003] In order to accurately know the amount of water you drink on a given day, there are already water cups that can measure the amount of water you drink. Usually, the water cup measures the amount of water you drink by measuring the changes in the volume inside the water cup with the help of sensors to measure and track the amount of water you drink. The sensors used on the market include optical sensors, weight sensors, ultrasonic sensors, etc. However, these technical solutions also have some shortcomings. For example, when it is necessary to arrange or use sensors to measure the amount of water you drink, the processing and assembly of the water cup is relatively complicated and the cost is relatively high.

[0013] Optionally, the cover body is further provided with an OLED display module, which is electrically connected to the PCB control board and the battery and is used to display the daily water intake calculated by the flow calculation chip.

[0014] Optionally, the cup cover capable of measuring the amount of water drunk also includes a Bluetooth module disposed in the accommodating cavity of the cover body and electrically connected to the PCB control board, and the PCB control board sends the amount of water drunk for the day calculated by the flow calculation chip to a mobile terminal associated therewith through the Bluetooth module.

[0015] Optionally, the battery is a rechargeable battery, which is connected to a charging port on the cover.

[0016] Another aspect of the present invention provides a water cup, comprising: a cup body, and a cup cover disposed on the cup mouth of the cup body and capable of measuring the amount of water drunk as described above.

[0017] Another aspect of the present invention provides a method for measuring drinking water, comprising: using the cup cover capable of measuring drinking water as described above, and comprising the following steps:

[0018] S1, obtaining the start time T1 of drinking water.

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] It should be noted that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", "back", "side", "circumferential" and the like in the present invention indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the words "first", "second" and the like are only used to distinguish multiple components or structures with the same or similar structures, and do not represent any special limitation on the arrangement order or connection relationship.

[0053] Please refer to Figures 1 to 7 The embodiment of the present invention provides a cup cover 100 capable of measuring drinking water, which is used to measure the drinking water of a user. The cup cover 100 capable of measuring drinking water includes: a cover body 1, a straw 2, a first induction ring 31, a second induction ring 32, a battery 4, and a PCB control board 5.

[0054] The cover 1 can be covered at the cup mouth d of the cup body 200, or used in conjunction with other water containers. The cover 1 has a receiving cavity b inside, and the receiving cavity is used to assemble various components. Specifically, the cover 1 includes a top cover 11 and a cover seat 12 that cover the receiving cavity b. The straw 2 is disposed through the cover 1, and the lower end of the straw 2 can extend into the cup body 200, including a connecting section 22 located in the receiving cavity b.

[0055] The PCB control board 5 is arranged in the accommodating chamber b and is integrated with a flow calculation chip 51. Specifically, the cover body seat 12 has an annular step surface a, and the PCB control board 5 is assembled and mounted on the annular step surface a. The flow calculation chip 51 is a prior art and will not be elaborated here. The battery 4 is arranged in the accommodating chamber b and is electrically connected to the PCB control board 5 for supplying power to the PCB control board 5. The first induction ring 31 and the second induction ring 32 are sleeved on the connecting section 22 at intervals and are both electrically connected to the PCB control board 5 for sensing and generating induction signals at corresponding positions of the water flow through the straw 2, and transmitting the induction signals to the PCB control board 5. In this embodiment, the connecting section 22 of the straw 2 is arranged vertically, so the first induction ring 31 and the second induction ring 32 are sleeved on the connecting section 22 at intervals from top to bottom, and there is a distance between the two. Of course, in other embodiments, the connecting section 22 of the straw 2 can also be arranged to meander downward, then the distance between the first induction ring 31 and the second induction ring 32 refers to the distance after the connecting section 22 of the straw 2 is unfolded.

[0056] The working process and principle / assembly steps of the embodiment of the present invention are roughly as follows:

[0057] When drinking water, when the water flows through the first induction ring 31 corresponding to the straw 2 for the first time, the first induction ring 31 generates a first induction signal, and transmits the first induction signal to the PCB control board 5, which is recorded by the PCB control board 5 as the start time of drinking water T1; then the water flows through the second induction ring 32 corresponding to the straw 2, the second induction ring 32 generates a second induction signal, and transmits the second induction signal to the PCB control board 5, which is recorded by the PCB control board 5 as the drinking speed calculation time T2. Since the distance between the position of the first induction ring 31 and the position of the second induction ring 32 corresponding to the straw 2 is known, the drinking water flow rate V is calculated according to the following formula (the drinking water flow rate here can be assumed to be a constant value after testing):

[0058]

[0059] When drinking stops, the water flows back to the first induction ring 31 corresponding to the straw 2. The first induction ring 31 generates a third induction signal and transmits the third induction signal to the PCB control board 5. The PCB control board 5 records it as the time T3 when drinking stops (since the time for the water flow to fall from the upper end of the straw 2 to the first induction ring 31 is extremely short, T3 can be approximately regarded as the time when drinking stops). The flow calculation chip 51 integrated in the PCB control board 5 calculates the amount of water drunk at a time according to the following formula:

[0060] Q=V*S*(T3-T1)

[0061] Wherein, S is the cross-sectional area of ​​the inner diameter of the straw 2; the amount of water drunk each time on the day is accumulated to obtain the amount of water drunk on the day.

[0062] Among them, Q is in mm; V is the drinking water flow rate in m / s; S is the cross-sectional area of ​​the inner diameter of the straw 2 in m2; (T3-T1) is the single drinking time in s.

[0063] In this way, the cup cover 100 capable of measuring the amount of water drunk can generate a sensing signal through the first sensing ring 31 and the second sensing ring 32 when the water flows through the corresponding position of the straw 2, and transmit the sensing signal to the PCB control board 5. The flow calculation chip 51 in the PCB control board 5 can calculate the single amount of water drunk through the time difference generated by the sensing signal, the inner diameter cross-sectional area of ​​the straw 2, the distance between the position of the corresponding first sensing ring 31 and the corresponding second sensing ring 32 of the straw 2, and other numerical values, and the amount of water drunk on the day can be calculated by accumulation. Since the cup cover can calculate the amount of water drunk without assembling a sensor, it has the advantages of relatively simple structure and low cost compared with the prior art.

[0064] Optionally, see Figure 4 , Figure 5 and Figure 7 In this embodiment, the first induction ring 31 and the second induction ring 32 are both capacitive induction rings, which are used to generate voltage change signals when water flows through the corresponding positions of the straw 2, and transmit the voltage change signals to the PCB control board 5. In this way, the time when the water flows to the corresponding positions of the first induction ring 31 and the second induction ring 32 of the straw 2 can be calculated by the voltage change signals, so as to facilitate the flow calculation chip 51 of the PCB control board 5 to calculate the single drinking amount.

[0065] Optionally, see Figure 4 and Figure 5 In this embodiment, the straw 2 further includes a nozzle section 21 and a hose section 23. The nozzle section 21 is disposed through the top cover 11, and the upper end of the connecting section 22 is connected to the nozzle section 21 and the lower end is connected to the hose section 23. Since the nozzle is a segmented structure, it is convenient to assemble the cup cover 100 capable of measuring the amount of drinking water.

[0066] In order to prevent water from penetrating into the accommodating cavity b of the cover body 1 from the connection between the suction nozzle section 21 and the connection section 22 when the user sucks water, thereby damaging various electrical components. Figure 5 and Figure 6 In this embodiment, an annular assembly groove c is formed at the lower end of the nozzle section 21, a waterproof sealing ring 24 is located in the annular assembly groove c, and the upper end of the connecting section 22 is inserted into the annular assembly groove c and presses the waterproof sealing ring 24. In this way, the nozzle section 21 and the connecting section 22 are tightly matched through the annular assembly groove c and the waterproof sealing ring 24 to achieve a waterproof and sealed connection. Furthermore, the bottom of the connecting section 22 protrudes from the bottom of the cover body seat 12 to form a plug-in tubular structure, and the upper end of the hose is inserted and fixed in the plug-in tubular structure of the connecting section 22.

[0067] To help users better stay hydrated and develop healthy drinking habits. Figure 7 In this embodiment, the cup cover 100 capable of measuring the amount of drinking water further comprises a drinking water reminder module 6 disposed in the accommodation cavity b of the cover body 1 and electrically connected to the PCB control board 5. Optionally, the drinking water reminder module 6 is at least one of a light reminder module, a sound reminder module, and a vibration reminder module. In this way, the user can be reminded to drink water at regular intervals (e.g., every hour) to ensure that the user has sufficient water intake throughout the day.

[0068] To help users understand the cumulative amount of water they drink on the day. Figure 7 In this embodiment, the cover body 1 is also provided with an OLED display module 7, which is electrically connected to the PCB control board 5 and the battery 4, and is used to display the daily water intake calculated by the flow calculation chip 51.

[0069] In order to increase interaction with users, it is convenient to display various drinking water data. Figure 7 In this embodiment, the cup cover 100 capable of measuring the amount of drinking water further comprises a Bluetooth module 8 disposed in the accommodation cavity b of the cover body 1 and electrically connected to the PCB control board 5. The PCB control board 5 sends the amount of drinking water calculated by the flow calculation chip 51 to the mobile terminal 300 associated therewith via the Bluetooth module 8. Specifically, the mobile terminal 300 can be configured with a corresponding APP, or associated with the cup cover 100 capable of measuring the amount of drinking water via a WeChat public account, which is not specifically limited here.

[0070] Optionally, see Figure 2 In this embodiment, the battery 4 is a rechargeable battery 4, which is connected to the charging interface 9 located on the cover 1. Specifically, in this embodiment, the charging interface 9 is a type-c interface. Of course, in other embodiments, the charging interface 9 can also be an Apple interface, a micro-USB interface, or a USB-C interface; there is no specific limitation.

[0071] Another aspect of the embodiment of the present invention provides a water cup 1000, comprising a cup body 200, and a cup cover 100 for measuring the amount of drinking water, which is disposed on the cup mouth d of the cup body 200. The cup cover 100 for measuring the amount of drinking water can be disposed in the cup mouth d of the cup body 200 by a detachable connection such as a snap connection, a screw connection, or a plug connection. Since the water cup 1000 has all the structures and connection relationships of the cup cover 100 for measuring the amount of drinking water, it has all the advantages of the cup cover 100 for measuring the amount of drinking water, which will not be described in detail here.

[0072] Another aspect of the embodiments of the present invention provides a method for measuring drinking water amount, using the cup cover 100 capable of measuring drinking water amount as described above, comprising the following steps:

[0073] S1, obtaining the start time T1 of drinking water. When drinking water, water flows through the first induction ring 31 corresponding to the straw 2. The first induction ring 31 generates a first induction signal and transmits the first induction signal to the PCB control board 5. The PCB control board 5 records it as the start time T1 of drinking water.

[0074] S2, calculate the drinking water flow rate V during drinking. When drinking water, the water flows through the second sensing ring 32 corresponding to the straw 2. The second sensing ring 32 generates a second sensing signal and transmits the second sensing signal to the PCB control board 5. The PCB control board 5 records it as the drinking water speed calculation time T2. The drinking water flow rate V is calculated according to the following formula:

[0075]

[0076] Wherein, L is the distance between the first induction ring 31 and the second induction ring 32 corresponding to the straw 2;

[0077] S3, obtaining the drinking stop time T3. When the drinking stops, the water flows back to the first induction ring 31 corresponding to the straw 2. The first induction ring 31 generates a third induction signal and transmits the third induction signal to the PCB control board 5. The PCB control board 5 records it as the drinking stop time T3.

[0078] S4, the flow calculation chip 51 integrated in the PCB control board 5 calculates the single drinking water amount according to the following formula:

[0079] Q=V*S*(T3-T1)

[0080] Wherein, S is the cross-sectional area of ​​the inner diameter of the straw 2;

[0081] S5. Calculate the amount of water you drink on that day, and add up the total amount of water you drink each time on that day to get the amount of water you drink on that day.

[0082] Since the method for measuring the amount of water drunk is completed using the cup cover 100 that can measure the amount of water drunk introduced above, it includes all the structures, connection relationships, and positional relationship characteristics of the cup cover 100 that can measure the amount of water drunk, and therefore has the same beneficial effects as the cup cover 100 that can measure the amount of water drunk, which will not be elaborated here.

[0083] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present application.
