Description

Technical Field

[0001] This invention relates to the field of smart drinking cup technology, and more particularly to a low-power smart drinking bottle. Background Technology

[0002] A smart water bottle is an electronic drinking device that integrates various sensors and displays. The built-in smart system is typically located on the bottle's lid. When the spout is activated, it triggers the electronic components to monitor flow rate and display temperature. However, due to the limited size of the lid, the battery inside is small and has a low capacity. The high power consumption of the electronic components results in a relatively short standby time for smart water bottles, requiring frequent charging, which is inconvenient and affects battery life. Summary of the Invention

[0003] The purpose of this invention is to provide a low-power smart water bottle to solve the problem that the high power consumption of smart water cups leads to inconvenience in use and affects their service life.

[0004] To achieve this objective, the present invention adopts the following technical solution: A low-power smart water bottle includes a cup body and a cup lid, the cup lid being equipped with a spout; the low-power smart water bottle further includes: A motherboard, wherein the motherboard is disposed inside the cup lid; A flow detection component is disposed inside the cup lid and communicates with the main board; the flow detection component is used to detect the drinking flow rate of the mouthpiece; A status detection component is disposed inside the cup lid and communicates with the main board. The status detection component is used to detect the status change of the cup body and send a status change signal to the main board. When the nozzle is opened, the mainboard starts or stops the flow detection component based on the received status change signal.

[0005] In some embodiments, after the nozzle is opened, when the flow rate detected by the flow rate detection component is greater than zero, the flow rate detection component sends a first flow rate signal to the motherboard, and the motherboard updates and displays the flow rate; otherwise, the flow rate detection component sends a second flow rate signal to the motherboard, and the motherboard shuts down the flow rate detection component.

[0006] In some embodiments, the low-power smart water bottle further includes a timer, which is communicatively connected to the motherboard. When the spout is opened, the timer is triggered to start timing when the motherboard receives the second flow signal. If the duration of the second flow signal received by the motherboard exceeds a first set time, the motherboard shuts down the flow detection component. If the duration of the second flow signal received by the motherboard exceeds the first set time, the motherboard emits an alarm sound or a warning light.

[0007] In some embodiments, the state detection component includes a vibration detector, an accelerometer, or a gyroscope, and the state change signal includes a vibration signal, an angle change signal, or an inertial force signal.

[0008] In some embodiments, the low-power smart water bottle further includes a position detection component, which is disposed inside the cup lid and communicates with the motherboard. The position detection component is used to detect the state of the mouthpiece. When the mouthpiece is open, the position detection component sends a first position signal to the motherboard. When the mouthpiece is open, the position detection component sends a second position signal to the motherboard.

[0009] In some embodiments, when the motherboard receives the first position signal, if it receives the state change signal, it activates the flow detection component; otherwise, it remains in standby mode. When the motherboard receives the second position signal, it deactivates the flow detection component and remains in standby mode.

[0010] In some embodiments, the position detection component includes a first magnet and a first Hall switch. The nozzle has mounting slots on both sides along the rotation axis. The first magnet is embedded in any one of the mounting slots. The first Hall switch is located on the motherboard. When the nozzle rotates to open and close, the first magnet triggers the first Hall switch to generate the first position signal and the second position signal, respectively.

[0011] In some embodiments, the traffic detection component includes: The housing is disposed on the cup lid. The housing has a cavity. The upper and lower side walls of the cavity are respectively provided with a water inlet and a water outlet. The axes of the water inlet and the water outlet are staggered. A rotor assembly, which is disposed within the cavity and is capable of rotating about the central axis of the housing, generates a changing magnetic field when the rotor assembly rotates; A flow control board is disposed on the cup lid and is communicatively connected to the main board; The second Hall switch is located on the flow control board and is used to detect the changing magnetic field generated when the rotor assembly rotates. The main board controls the activation and deactivation of the second Hall switch through the flow control board.

[0012] In some embodiments, the cup lid includes an outer shell and an inner shell, with an installation space formed between the outer shell and the inner shell. The main board, the status detection component, the flow control board, and the second Hall switch are all installed in the installation space. The outer side of the bottom surface of the inner shell is provided with a receiving groove, and the outer shell is disposed in the receiving groove. The bottom of the receiving groove is provided with a stepped groove facing the outer side of the installation space. The flow control board is disposed on the groove opening end face of the stepped groove, and the second Hall switch is disposed on the groove bottom face of the stepped groove.

[0013] In some embodiments, the inner shell is provided with a handle and a display screen, the display screen is disposed on the handle and communicates with the motherboard, and the display screen is used to display the water flow rate and the light.

[0014] The beneficial effects of this invention are: The low-power smart water bottle provided by this invention achieves dual-verification activation of the flow detection component by incorporating a status detection component. The flow detection component is only activated after the mainboard receives a status change signal after the spout is opened. Compared to existing technologies where the mainboard activates the flow detection component immediately upon spout opening, this invention adds the judgment of status change signals. Specifically, it only recognizes a drinking intention when the cup vibrates after the spout is opened. This avoids the power consumption problem caused by the flow detection component activating prematurely or remaining continuously when there is no drinking action after the spout is opened. It reduces the power consumption of the flow detection component, improves the overall standby time of the mainboard, extends battery life, and makes it more convenient to use.

[0017] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0020] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0021] This invention provides a low-power smart water bottle, such as... Figures 1-7 As shown, the device includes a cup body 1, a cup lid 2, a main board 4, a flow detection component 5, and a status detection component 6. The cup lid 2 has a spout 3, which can be rotated to open and close. The main board 4 is located inside the cup lid 2. The flow detection component 5 is located inside the cup lid 2 and is communicatively connected to the main board 4. The flow detection component 5 is used to detect the drinking flow rate of the spout 3. The status detection component 6 is located inside the cup lid 2 and is communicatively connected to the main board 4. The status detection component 6 is used to detect changes in the status of the cup body 1 and send status change signals to the main board 4. When the spout 3 is opened, the main board 4 starts or stops the flow detection component 5 based on the received status change signal.

[0022] In existing smart water bottles, the flow detection component 5 automatically activates after the spout 3 is opened. However, when there is no drinking action after the spout 3 is open, the flow detection component 5 continues to consume power, affecting the overall standby time of the mainboard 4. To address the high power consumption issue of the flow detection component 5, this invention incorporates a status detection component 6 within the cup lid 2. This component detects changes in the state of the cup body 1, enabling dual-verification activation of the flow detection component 5. When the spout 3 is opened, if the mainboard 4 receives a status change signal, it activates the flow detection component 5; otherwise, it remains off, achieving low-power standby. The status detection component 6 includes a vibration detector, accelerometer, or gyroscope, and the status change signal includes, but is not limited to, vibration signals, angle change signals, or inertial force signals. The following explanation uses the example of a vibration detector on the mainboard 4 detecting vibration signals. The cup body 1 vibrates only when the spout 3 is opened, indicating a user's intention to drink. This avoids the power consumption problem caused by the flow detection component 5 prematurely or continuously turning on when there is no drinking action after the spout 3 is opened. This reduces the power consumption of the flow detection component 5, improves the overall standby time of the mainboard 4, extends battery life, and makes it more convenient to use. It should be explained that the opening of the spout 3 generally causes the cup body 1 to vibrate, as does the flow of water during drinking, and holding the cup body 1 while drinking also causes vibration or changes in posture. The status detection component 6 can detect these vibrations or posture changes of the cup body 1 and send a status change signal to the mainboard 4. Upon receiving the status change signal, the mainboard 4 activates the flow detection component 5.

[0023] In some embodiments, after the nozzle 3 is opened, when the flow rate detected by the flow rate detection component 5 is greater than zero, the flow rate detection component 5 sends a first flow rate signal to the main board 4, and the main board 4 updates and displays the flow rate; otherwise, the flow rate detection component 5 sends a second flow rate signal to the main board 4, and the main board 4 shuts down the flow rate detection component 5.

[0024] like Figure 8As shown, the low-power smart water bottle provided by this invention initiates intelligent control after the spout 3 is opened. After the spout 3 is opened, the mainboard 4 waits for a status change signal. If the mainboard 4 receives a status change signal, it assumes there is a drinking motivation and activates the flow detection component 5. When an actual drinking action occurs, the flow detection component 5 detects the water flow rate of the spout 3 and sends a first flow signal to the mainboard 4. If no actual drinking action occurs, there is no water flow from the spout 3, and the flow detection component 5 sends a second flow signal to the mainboard 4. No flow signal indicates that the user has stopped drinking, and the mainboard 4 can then turn off the flow detection component 5 to achieve low-power control. After receiving the first flow signal, the mainboard 4 stores and calculates the flow data, sums the multiple drinking flows, and displays the accumulated flow. Correspondingly, the mainboard 4 can set a daily water consumption limit and, after subtracting the flow rates from multiple drinking actions, displays the remaining daily water consumption limit for user reference. By setting a reset button on the lid connected to the mainboard 4, the daily water consumption limit can be reset to zero for updating.

[0025] In some embodiments, the low-power smart water bottle also includes a timer, which is communicatively connected to the motherboard 4. When the spout 3 is opened, the timer is triggered to start timing when the motherboard 4 receives the second flow signal. If the duration of the second flow signal received by the motherboard 4 exceeds a first set time, the motherboard 4 shuts down the flow detection component 5.

[0026] It is understandable that users may have intermittent drinking habits. If the mainboard 4 quickly shuts down the flow detection component 5 after receiving the second flow signal, there may be frequent starting and stopping of the flow detection component 5. Therefore, this embodiment sets a timer to time the interval between the two first flow signals. If no first flow signal is received again within a first set time, the flow detection component 5 is shut down, and the user is prompted to close the nozzle 3, thus achieving low power consumption control. The first set time can be set by the user or initially set by the mainboard 4, generally not exceeding five minutes. In addition, when the nozzle 3 is opened, the opening action of the nozzle 3 will generate vibration, and the status detection component 6 will send a status change signal to the mainboard 4, that is, there is a situation where the flow detector is also activated after the nozzle 3 is opened. Therefore, in this embodiment of the invention, the timer is triggered and starts timing after the nozzle 3 is opened. If the mainboard 4 does not generate a first flow signal within the second set time, that is, no actual drinking occurs, the mainboard 4 will shut down the flow detection component 5 and continue to wait for the status change signal.

[0027] In some embodiments, when the duration of the second flow signal received by the motherboard 4 exceeds a first preset time, the motherboard 4 emits an alarm sound or a warning light.

[0028] It is understandable that if no water flow is generated and no status change signal is generated after the nozzle 3 is opened, it indicates that the user has no motivation to drink. In this case, the flow detection component 5 can be shut down to achieve low power consumption control. The main board 4 emits an alarm sound or warning light to prompt the user to close the nozzle 3 and shut down the flow detection component 5. If the user does not close the nozzle 3, the main board 4 remains in standby mode and continues to monitor status change signals. Upon receiving a status change signal, the flow detection component 5 will be restarted.

[0029] In some embodiments, the low-power smart water bottle also includes a position detection component, which is disposed inside the cup lid 2 and communicates with the motherboard 4. The position detection component is used to detect the state of the mouthpiece 3. When the mouthpiece 3 is open, the position detection component sends a first position signal to the motherboard 4. When the mouthpiece 3 is open, the position detection component sends a second position signal to the motherboard 4.

[0030] It is understandable that by setting up a position detection component, the open or closed state of the nozzle 3 can be sent to the mainboard 4, so that the mainboard 4 can detect and receive the state change signal when the nozzle 3 is open. When the nozzle 3 is closed, the mainboard 4 does not take any action on the state change signal, and the flow detection component 5 is also in the off state.

[0031] In some embodiments, when the mainboard 4 receives a first position signal, it indicates that the nozzle 3 is in the open state. If the mainboard 4 receives a state change signal, it indicates that the user has a drinking intention, and the cup body 1 or the cup lid 2 has generated a slight vibration or movement. The mainboard 4 then activates the flow detection component 5 to detect the drinking flow of the nozzle 3. Otherwise, it remains in standby mode until it receives a state change signal to activate the flow detection component 5, or until it receives a second position signal, at which point the nozzle 3 closes and the mainboard 4 operates in silent mode, achieving low-power control.

[0032] When motherboard 4 receives the second position signal, it shuts down the flow detection component 5 and enters standby mode, ending one drinking action control cycle. The next intelligent control process will only begin when motherboard 4 receives the first position signal again.

[0033] In some embodiments, the position detection component includes a first magnet 7 and a first Hall switch 8. The first magnet 7 is disposed on the nozzle 3, and the first Hall switch 8 is disposed on the main board 4. When the nozzle 3 is rotated to open and close, the first magnet 7 triggers the first Hall switch 8 to generate a first position signal and a second position signal respectively.

[0034] like Figure 2 and Figure 3As shown, the suction nozzle 3 is rotatably mounted on the cup lid 2. By setting the first magnet 7 on the suction nozzle 3, a magnetic field change occurs when the suction nozzle 3 rotates. After detecting the magnetic field change, the first Hall switch 8 sends a Hall signal to the main board 4. It has the advantages of small size and fast response, and low power consumption.

[0035] In some embodiments, the suction nozzle 3 is provided with mounting grooves 31 on both sides along the rotation axis, and the first magnet 7 is embedded in any one of the mounting grooves 31.

[0036] Specifically, the suction nozzle 3 has rotating shafts 32 on both sides, which are rotatably mounted on the cup lid 2. Along the axial direction of the rotating shafts 32, the suction nozzle 3 has mounting grooves 31 on both sides, and the first magnet 7 is embedded in the mounting grooves 31, making full use of the structural space on the suction nozzle 3 without increasing the installation volume. When the suction nozzle 3 rotates, the direction of the magnetic field lines of the first magnet 7 changes, making it easier for the first Hall switch 8 to detect the change in magnetic field and thus generate a Hall signal. Compared with the prior art where the first Hall switch 8 generates a Hall effect through changes in the position and distance of the first magnet 7, the Hall signal is more accurate.

[0037] In some embodiments, the flow detection component 5 includes a housing 51, a rotor assembly 52, a flow control board 53, and a second Hall switch 54. The housing 51 is disposed on the cup lid 2 and has a cavity 511. The upper and lower side walls of the cavity 511 are respectively provided with an inlet 512 and an outlet 513, and the axes of the inlet 512 and the outlet 513 are staggered. The rotor assembly 52 is disposed in the cavity 511 and can rotate around the central axis of the housing 51. When the rotor assembly 52 rotates, it generates a changing magnetic field. The flow control board 53 is disposed in the cup lid 2 and is communicatively connected to the main board 4. The Hall switch 54 is disposed on the flow control board 53. The second Hall switch 54 is used to detect the changing magnetic field generated when the rotor assembly 52 rotates, and the flow control board 53 converts the Hall signal of the second Hall switch 54 into a flow signal and sends it to the main board 4. The main board 4 controls the start and stop of the second Hall switch 54.

[0038] Combination Figures 4-7As shown, the rotor assembly 52 is sealed and installed in the cavity 511 of the housing 51. The rotor assembly 52 includes multiple rotating blades 522 and multiple second magnets 521. The second magnets 521 rotate with the rotating blades 522 and generate a changing magnetic field. When water in the cup 1 enters the cavity 511 through the inlet 512, it drives the rotating blades 522 to rotate, which in turn drives the second magnets 521 to rotate. The second Hall switch 54 detects this changing magnetic field and generates a Hall signal, which is sent to the flow control board 53. When the flow rate is greater than zero, it serves as the first flow signal. The flow control board 53 sends the first flow signal to the main board 4. After receiving the first flow signal, the main board 4 saves and updates the flow data. When the flow rate is zero, there is no Hall signal. At this time, the flow control board 53 sends a second flow signal to the main board 4, indicating that the user has not drunk water, and the operation of shutting down the flow detection component 5 can be performed. The axes of the inlet 512 and the outlet 513 are respectively along the axis of the rotor assembly 52. ​​By reasonably setting the circumferential angle between the axis of the inlet 512 and the axis of the outlet 513, the rotation drive of the rotating blade 522 can be realized, thereby realizing flow detection.

[0039] In some embodiments, the cup lid 2 includes an outer shell 21 and an inner shell 22, with an installation space formed between the outer shell 21 and the inner shell 22. The main board 4, the status detection component 6, the flow control board 53, and the second Hall switch 54 are all installed in the installation space. The outer side of the bottom surface of the inner shell 22 is provided with a receiving groove 221, and the shell 51 is disposed in the receiving groove 221.

[0040] like Figure 1 and Figure 2 As shown, the inner shell 22 is used to connect the cup body 1, and the outer shell 21 is used to seal the inner shell 22. The main board 4 is set in the installation space and fixed on the inner shell 22. When the status detection component 6 is a vibration detector, it can be directly set on the main board 4. When the status detection component 6 is a gyroscope or other instrument, it can be directly fixed on the inner shell 22 and communicate with the main board 4. Figure 7 The second Hall switch 54 is located on the lower surface of the flow control board 53, so that the second Hall switch 54 is as close as possible to the rotor assembly 52 to improve the flow detection accuracy. Figure 6 The bottom outer side of the inner shell 22 is recessed to form a receiving groove 221. The shell 51 is located in the receiving groove 221 and is flush with the end face of the receiving groove 221. It abuts and seals against the inner side wall of the receiving groove 221, so that water can only enter the cavity 511 through the water inlet 512.

[0041] In some embodiments, the bottom of the receiving groove 221 is provided with a stepped groove 222 facing the outer side of the installation space, a flow control plate 53 is provided on the groove opening end face of the stepped groove 222, and a second Hall switch 54 is provided on the bottom surface of the stepped groove 222.

[0042] like Figure 5As shown, the bottom of the receiving groove 221 is flat, and the bottom of the stepped groove 222 is flat. When the flow control plate 53 is embedded and installed on the end face of the stepped groove 222, the upper surface of the flow control plate 53 is flush with the outer surface of the receiving groove 221 facing the installation space, so as to align and fix it. The second Hall switch 54 is placed at the bottom of the stepped groove 222, which can further reduce the distance between the second Hall switch 54 and the rotor assembly 52 and improve the flow detection accuracy. The height difference between the bottom of the stepped groove 222 and the end face of the groove is just right for placing the second Hall switch 54 to achieve stable installation. The flow control plate 54 confines the second Hall switch 54 to the bottom of the stepped groove 222.

[0043] In some embodiments, the housing 21 is provided with a handle 211 and a display screen 212. The display screen 212 is located on the handle 211 and is connected to the motherboard 4. The display screen 212 is used to display the water flow rate and the light.

[0044] like Figure 2 A display screen 212 is installed above the handle 211 to display the water flow rate and indicator lights. When the main board 4 receives the first flow signal, it collects and saves the flow data and updates the flow rate, displaying the water flow rate or remaining target water volume on the display screen 212 to remind the user. The indicator lights are set to colorful lights, which will turn on after the nozzle 3 is opened and the flow detection component 5 is activated. When the main board 4 alarms, it can remind the user through the flashing pattern or color of the lights, including reminding them to drink water or to close the nozzle 3. The specific settings can be initially configured according to actual conditions.

[0045] The low-power smart water bottle provided in this embodiment of the invention adds a status detection component 6 inside the cup lid 2, enabling the motherboard 4 to control the start and stop of the flow detection component 5 by receiving the first position signal and the status change signal, thereby reducing the overall power consumption of the flow detection component 5, improving the standby time of the motherboard 4 and extending the service life of the motherboard 4.

[0046] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
