[0026] Example 1

[0027] This embodiment provides a water intake device, which is improved on the basis of the structure of the existing water intake tap, such as Figure 1As shown, it includes a water tap body. The water tap body can adopt the existing water tap structure, including a valve stem 1, a valve core, a shell 2 and other components. Its specific structure will not be described in detail here.

[0028] The outer periphery of the water faucet body is provided with a cabinet 3, which is fixedly connected to the outer shell 2 of the water faucet body. The side water outlet of the water faucet body and the cover 4 installed at the water outlet, as well as the terminal connection piece 5 at the bottom are all extended to the outside of the cabinet. The cover 4 and the terminal connection piece 5 can be made of existing technology, and will not be described in detail here.

[0029] When in use, the cabinet body 3 is completely installed on the ground.

[0030] The upper half of the space inside the cabinet 3 is used to install the MCU microprocessor and the various modules connected to it as the control system installation area 6. A cabinet door 7 is provided on the lower half of the front cabinet wall of the cabinet. A door lock is provided between the cabinet door 7 and the front cabinet wall. The door lock can use an existing door lock, and its specific structure will not be described in detail here.

[0031] The edge of the cabinet door 7 is provided with a rubber ring, which is used to fit with the front cabinet wall to achieve a waterproof effect.

[0032] A locking structure is provided on the top of the water tap body, and the valve stem of the water tap body passes through the locking mechanism and extends above the cabinet. The locking mechanism is located inside the cabinet and is used to lock and fix the valve stem.

[0033] The locking mechanism includes a box body 8, which is fixed on the top of the water tap body shell. The bottom box wall and the top box wall of the box body 8 are both provided with holes for the valve stem of the water tap body to pass through. The valve stem 1 passes through the box body 8 and the cabinet and extends to the top of the cabinet.

[0034] A cover shell 9 is arranged above the box body 8, and the cover shell 9 is fixedly connected to the top box wall of the box body 8. The cover shell 9 is threadedly connected to the valve stem 1. The structure of the cover shell 9 can adopt the top structure of the existing water tap. A cap is arranged on the top of the valve stem 1. When water is needed, the cap is opened and the valve stem is rotated by a cross wrench. The cap can adopt the existing technology, and its specific structure will not be described in detail here.

[0035] like Figure 3 As shown, a ratchet 10 is fixed to the rod section of the valve stem located in the box body 8. The ratchet 10 is coaxially arranged with the valve stem 1. The ratchet 10 can rotate synchronously with the valve stem 1 around its own axis.

[0036] A pawl 11 is provided on one side of the ratchet 10. In the present embodiment, two pawls 11 are provided. Both pawls 11 adopt a right-angled triangle structure. The side surface corresponding to a right-angled side of the pawl 11 is fixedly connected to the moving rod 12. The axis of the moving rod 12 is horizontally arranged, and the diagonal side of the side surface is used to be inserted into two adjacent tooth grooves of the ratchet 10. The plane where the other right-angled side is located is used to contact the radial plane of the teeth of the ratchet 10 to lock the ratchet 10.

[0037] A fixed rod 13 is provided on the outside of the moving rod, and the fixed rod 13 is fixed inside the box body 8. An elastic member is provided between the fixed rod 13 and the moving rod 12. In this embodiment, the elastic member is a spring 14, one end of the spring 14 is fixed to the fixed rod 13, and the other end is fixedly connected to the moving rod 12. The spring 14 can apply elastic force to the moving rod 12, so that the pawl 11 is stuck in the wheel tooth groove of the ratchet 10, thereby realizing the locking and fixation of the ratchet 10.

[0038] At the same time, a first magnet 15 is fixed in the box body 8 at a first set position. The first set position allows the moving rod 12 to be adsorbed and fixed to the first magnet 15 after the pawl 11 is inserted into the tooth groove of the ratchet 10. The adsorption force of the first magnet 15 and the elastic force of the spring 14 jointly lock the pawl 11 in the tooth groove, thereby preventing the ratchet 10 from rotating.

[0039] The movable rod 12 is connected to a movable driving mechanism, which can drive the movable rod to actively move, thereby realizing the pawl to disengage from the wheel groove of the ratchet, and then the locking mechanism contacts the locking state of the ratchet, and the user can normally rotate the valve stem 1 to perform water extraction operations.

[0040] The mobile driving mechanism includes a first connecting rod 16 and a second connecting rod 17 arranged in parallel, one end of the first connecting rod 16 is hinged to one side end of the fixed rod 13, and the other end is hinged to the same side end of the moving rod 12, one end of the second connecting rod 17 is hinged to the other end of the fixed rod 13, and the other end of the second connecting rod 17 is hinged to the moving rod 12, and a parallelogram connecting rod mechanism is formed among the first connecting rod 16, the second connecting rod 17, the fixed rod 13 and the moving rod 12.

[0041] A cam 18 is provided on one side of the first connecting rod 16, and the cam 18 is connected to a rotating driving element. The rotating driving element adopts a DC motor (omitted in the figure and not drawn). The output shaft of the DC motor is connected to the cam 18 and can drive the cam 18 to rotate. The DC motor is fixed on a motor seat, and the motor seat is fixed inside the box 8.

[0042] The first connecting rod 16 is in contact with the cam 18, and the cam 18 rotates under the action of the DC motor, which can drive the first connecting rod 16 to swing, so that the moving rod overcomes the elastic force of the spring 14 and the adsorption force of the first magnet 12 and moves toward the fixed rod 13, so that the pawl 11 disengages from the gear tooth groove of the ratchet 10.

[0043] The DC motor is connected to the microprocessor via a drive module 19 in the cabinet and can receive instructions from the microprocessor to operate.

[0044] The driving module 19 adopts the existing DC motor driving chip.

[0045] The microprocessor adopts the existing MCU microprocessor 20, integrating 4 low-resistance MOS and forward, reverse, brake and stop functions; the motion state control of the DC motor is realized by the high and low levels of the corresponding control resistor of the MCU microprocessor 20.

[0046] One end of the moving rod 12 is hinged to the first connecting rod 16 , and the other end thereof extends out of the box body 8 through a long hole provided in the box body 8 and is located inside the cabinet body 3 .

[0047] Preferably, a first in-position switch 21 is provided at the third setting position on one side of the cam 18, and the first in-position switch 21 is a touch switch, and the third setting position is configured as follows: when the cam 18 rotates until the pawl 11 is engaged in the tooth groove of the ratchet 10, the cam 18 touches the first in-position switch 21, and the first in-position switch 21 is connected to the MCU microprocessor 20, and can send a signal of the ratchet locking state to the MCU microprocessor 20.

[0048] A second in-position switch 22 is provided at the fourth setting position on one side of the second connecting rod 17. The second in-position switch 22 is a touch switch. The fourth setting position is configured as follows: when the cam 18 rotates until the pawl 11 is disengaged from the gear groove of the ratchet 10, the second connecting rod 17 touches the second in-position switch 22. The second in-position switch 22 is connected to the MCU microprocessor 20 and can send a signal of the ratchet contact locking state to the MCU microprocessor 20.

[0049] When an emergency such as a fire occurs and the DC motor cannot be immediately controlled to work and contact the ratchet locking state or the DC motor fails but water is needed immediately, it is necessary to force the locking state to be contacted. Therefore, in this embodiment, one end of the moving rod 12 is hinged to the first connecting rod 16, and the other end extends to the outside of the box body 8 through the long hole provided in the box body 8. Correspondingly, an emergency window 23 is provided on the cabinet body, and the position of the emergency window 23 corresponds to the position of the moving rod. After breaking the emergency window 23, the staff can operate the moving rod 12 for forced movement, so that the pawl 11 disengages from the ratchet 10 and contacts the locking state.

[0050] In order to lock and fix the moving rod 12 after forced movement, a second magnet 24 is fixed in the second setting position in the box 8. The second setting position is configured so that when the pawl 11 is separated from the tooth groove of the ratchet 10 in an emergency unlocking situation, the moving rod 12 can be adsorbed and fixed with the second magnet 24. After the second magnet 24 is adsorbed and fixed with the moving rod 12, the elastic force of the spring 14 can be overcome, so that the pawl 11 is always kept outside the tooth groove of the ratchet 10, which is convenient for the staff to turn the valve stem to take water.

[0051] The locking mechanism of this embodiment utilizes the spring 14 and the first magnet 15 to jointly act on the fixed pawl 11, so that the pawl 11 remains inserted into the wheel tooth groove, and the pawl 11 prevents the ratchet 10 from rotating, thereby achieving the locking of the valve stem 1, and playing the function of preventing illegal water extraction. The entire locking mechanism is a purely mechanical structure, and no power is required when locking, which reduces the consumption of electricity and reduces the cost of the water extraction device when it is working.

[0052] When it is necessary to draw water normally, the cam 18 is driven to rotate by the DC motor. The cam 18 acts on the first connecting rod 16, and its force overcomes the elastic force of the spring 14 and the adsorption force of the first magnet 15 to drive the moving rod 12 to move, so that the pawl 11 disengages from the ratchet 10. At this time, the valve stem 1 can be rotated normally to draw water. After the water is drawn, the DC motor reverses. Under the action of the spring 14, the pawl 11 re-engages with the ratchet 10 to lock the valve stem 1, thereby preventing illegal water drawing.

[0053] In this embodiment, Figure 2 As shown, a pressure sensor 25 and an ultrasonic flow meter 26 are installed at the bottom of the water flow channel of the water tap body near the water inlet. The pressure sensor is used to detect the water flow pressure in the water flow channel of the water tap body, and the ultrasonic flow meter is used to detect the water flow velocity.

[0054] The pressure sensor 25 and ultrasonic flow meter 26 are installed on the outer shell 2 of the water tap body, and their probes extend into the water flow channel. The pressure sensor 25 and ultrasonic flow meter 26 are both located in the lower half of the space inside the cabinet 3. After opening the cabinet door, the pressure sensor 25 and ultrasonic flow meter 26 can be inspected and maintained.

[0055] A water sensor 27 is installed at the side water outlet on the upper part of the water tap body. The water sensor 27 is fixed on the shell 2 of the water tap body, and its probe extends into the water outlet of the water flow channel. The water sensor 27 is located inside the cabinet 3.

[0056] like Figure 4As shown, the ultrasonic flow meter 26 is connected to the MCU microprocessor 20 through the 485 acquisition module 28 in the cabinet. The 485 acquisition module 28 can collect data from the ultrasonic flow meter 26 and transmit it to the MCU microprocessor 20 through the MODBUS communication protocol.

[0057] The pressure sensor 25 and the water immersion sensor 27 are connected to the MCU microprocessor 20 via the ADC operational amplifier module 29 in the cabinet 3 , and can transmit the collected information to the MCU microprocessor 20 .

[0058] The ADC operational amplifier module 29 can adopt the existing technology, and its output end is connected to the input end of the MCU microprocessor 20. For voltage acquisition, the external voltage flows into the voltage follower after being divided by two resistors. At this time, the input voltage and the output voltage are consistent, and then the voltage is input to the ADC acquisition pin of the MCU microprocessor 20 through the current limiting resistor battery; for current acquisition, the external current is converted into a voltage form by a resistor and flows into the voltage follower. At this time, the input voltage and the output voltage are consistent, and then the voltage is input to the ADC acquisition pin of the MCU microprocessor 20 through the current limiting resistor; accurate pressure and water immersion data are obtained through the internal filtering algorithm of the MCU microprocessor 20.

[0059] The MCU microprocessor 20 is wirelessly connected to the cloud platform management system via the CAT1 module 30, and the data received by the MCU microprocessor 20 can be wirelessly transmitted to the cloud platform management system for data analysis and processing.

[0060] The CAT1 module 30 can use an existing module. The CAT1 module 30 supports a maximum downstream rate of 10Mbps and a maximum upstream rate of 5Mbps. The CAT1 module 30 can receive and send data at a relatively fast speed. At the same time, it has high security. It supports a variety of network protocols and encryption methods to protect the data security of users. The input and output ends of the CAT1 module 30 are connected to the USART receiving and transmitting ends of the MCU microprocessor 20, and after the voltage is increased to 3.8V for power supply through the boost module, the MCU microprocessor 20 sends AT instructions through the serial port to establish a connection with the TCP and UDP servers. Once the connection is successfully established, the water intake device can send data to the server of the PTZ management platform or receive data from the server through the TCP or UDP protocol; at the same time, since the TCP or UDP protocol is used for data transmission and remote upgrade, faster and more stable data transmission and remote upgrade can be achieved, avoiding the limitations and inconveniences of traditional wired communication methods.

[0061] An automatic drain valve 31 is installed at the water flow channel below the water immersion sensor 27. The automatic drain valve 31 can use existing equipment, and its operation is based on the density and pressure difference of water. Under normal circumstances, the water level in the water tap is higher than the automatic drain valve and is in a closed state. When the water tap has not been used for a period of time (such as a week), the substances inside the water (such as sediments and debris) will gradually change, and the debris will gradually adhere to the automatic drain valve. At this time, when the water pressure drops to a certain level, the spring of the automatic drain valve 31 pushes the piston body back to its original position, and the water in the water flow channel of the water tap can be smoothly discharged from the inside of the water tap.

[0062] The MCU microprocessor 20 is also connected to a power module 32, which is installed inside the cabinet 3. The power module 32 can use an existing module. Its battery outputs a 3.6V voltage, which passes through the anti-reverse connection diode D1 and then through the filter capacitor to the input of the power chip. The output chip outputs a 3V voltage to provide a safe and clean voltage for the MCU microprocessor 20 and other modules. The output chip uses low-power components, and the operating current is about 1uA. In the standby state, almost no electricity is consumed. These characteristics enable the water intake device to maintain a stable operating state within 6 years, while reducing maintenance costs and the frequency of battery replacement.

[0063] The MCU microprocessor 20 is also connected to a boost module 33, which can use existing technology and is divided into two paths. One path boosts 3.8V to power the CAT1 module, and the other path boosts 12V to power external devices such as pressure sensors. The 3.8V and 12V boost principles are consistent, and existing technology can be used, which will not be described in detail here.

[0064] The MCU microprocessor 20 is also connected to a Bluetooth module 34 located in the cabinet, and can communicate with the mobile phone through the Bluetooth module 34 to prompt the status of the water intake device and provide a solution to the fault problem; the water intake device communicates wirelessly with the mobile phone APP to monitor the status information of the water intake device in real time. When the water intake device is idle, the APP will display the status information of "available"; when the water intake device is in use, the APP will display the status information of "occupied"; when the water intake device fails, the APP will display the status information of "fault". At the same time, the mobile phone APP will also recommend the nearest available water intake device based on the user's location information.

[0065] The Bluetooth module 34 can adopt the existing technology. The Bluetooth module 34 is based on the embedded low-power Bluetooth protocol stack and GATT service, and realizes low-power, short-distance, high-speed and low-cost data transmission through the 2.402-2.480Ghz frequency hopping technology. The input and output terminals of the Bluetooth module 34 are connected to the IO port of the MCU microprocessor through a current-limiting resistor. After the MCU microprocessor powers on the Bluetooth module, it sends corresponding instructions through the USART of the MCU microprocessor 20. It will search for other Bluetooth devices and establish a connection. After the connection is successfully established, the Bluetooth modules can communicate with each other and transmit data. The water extraction device data is read and analyzed through the mobile phone APP function and a solution is provided for the fault problem. It is convenient for users to understand the status of the water extraction device anytime and anywhere and perform corresponding operations, which improves the convenience and efficiency of use.

[0066] The MCU microprocessor 20 is also connected to a battery voltage acquisition module 35 for collecting the voltage information of the battery in the power module. The battery voltage acquisition module 35 can be made of existing technology. The MOS tube is controlled by a triode to make it conductive. Two voltage-dividing resistors divide the battery voltage and input it into the ADC acquisition pin of the MCU microprocessor. The MCU microprocessor 20 obtains the battery voltage value through an internal filtering algorithm. When the battery voltage value is lower than the preset battery threshold, the water-collecting device will prompt the user to replace the battery. Such a design can effectively monitor the battery status and promptly remind the user to replace the battery, ensuring the stable operation of the system.

[0067] The cabinet is also equipped with a positioning module, which uses an existing Beidou module 36. The Beidou module 36 is connected to the MCU microprocessor 20. The MCU microprocessor 20 receives signal information from Beidou multiple satellites. The MCU microprocessor 20 obtains the location information of the water intake device by analyzing the satellite data, including longitude, latitude, altitude and other information. In combination with the collected information, it is determined whether the water intake device has been stolen based on whether the difference between the longitude and latitude collected twice exceeds the set threshold. At the same time, the time is calibrated in seconds to ensure the time accuracy of the water intake device.

[0068] After the water intake device completes the collection of its own location information, it transmits the data to the cloud platform management system through the CAT1 module to achieve real-time monitoring and positioning of the water intake device. When the water intake device fails or has an abnormal situation, the Beidou module can provide location information to help maintenance personnel quickly locate and go to the fault site for repair and processing.

[0069] The cabinet is also equipped with a posture sensor, which is connected to the MCU microprocessor 20 through a posture module 37. The posture module 37 can use an existing module. The posture sensor uses a three-axis acceleration sensor and a gyroscope to detect the posture information of the water intake device, including angle, direction and other information. The three-axis acceleration sensor and the gyroscope can detect the acceleration and angular velocity changes in three axes, thereby obtaining the posture information of the water intake device. Through the detection of the posture sensor, the water intake device can monitor the posture of the device. For example, when the water intake device tilts or falls, the posture sensor can detect the corresponding changes, and control the corresponding alarm device through the MCU microprocessor 20 to issue a corresponding alarm, thereby ensuring the normal use and stability of the water intake device.

[0070] By collecting Beidou positioning and three-dimensional posture information, combined with the internal algorithm of MCU, the water intake device status is automatically monitored 24 hours a day to prevent accidents. Whether the water intake device is in abnormal conditions such as knocking over, tilting or theft, the water intake device can monitor in real time and respond quickly. Once an abnormality occurs, the system will immediately activate the alarm function, notify the management personnel, and accurately track the location of the water intake device, thereby minimizing water waste and equipment value loss.

[0071] The MCU microprocessor 20 is also connected to an LCD display module 38, which is fixed to the upper half of the cabinet wall on the front side of the cabinet body 3. The LCD display module 38 uses a 10.1-inch TFT-LCD display screen with a resolution of 1024*RGB*600. A transparent cover plate fixed to the cabinet door is provided on the outside of the display screen, which can be used to display the status information, location information, usage records and other information of the water intake device. The user can view this information through the LCD display screen to understand the working status and related data of the water intake device. It can also be used as an operating interface for the water intake device, and various operations can be performed through the LCD display screen, such as setting the water level, etc. The operating interface can provide simple and intuitive icons or text prompts, so that the user can operate conveniently.

[0072] The MCU microprocessor 20 is also connected to a voice module 39 installed in the cabinet. The voice module 39 can use an existing module. By communicating with the IIC of the MCU microprocessor 20, the voice module 39 chip has a 16-bit PWM output, which can directly drive an 8-ohm 0.25W speaker, and can output the status information, location information, and usage records of the water intake device to the user in the form of voice. When the water intake device fails, the voice module can output the corresponding fault prompt information in the form of voice to inform the user of the specific fault situation and solution. In this way, the user can discover and deal with the fault problem in time. And the coordinated use of the voice module and the display screen can realize interactive operation.

[0073] The TFT-LCD display has the advantages of high definition, high brightness, and high contrast, and can provide clear images and text information, allowing users to read and operate easily. In addition, the module also has a touch screen function, allowing users to operate with fingers or other touch tools, achieving fast response and convenient operation experience. Users can intuitively view the information of the water intake device. Whether it is water consumption, water use time or cost, it can be seen at a glance, and users can set and modify parameters of the water intake device by touch. At the same time, it is equipped with a voice module to broadcast the relevant information of this water use in real time. Even if the user does not read the information on the display module, he can understand the details of this water use through voice broadcast.

[0074] The MCU microprocessor is also connected to a radio frequency module 40 installed in the cabinet. The radio frequency module 40 can use existing technology. The radio frequency module 40 uses a radio frequency chip. The radio frequency IC card has a memory with a certain data format. When the radio frequency chip writes to the radio frequency card, it passes through a low-pass filter circuit to form a low-pass filter to filter out useless signals above 13.56Mhz. After adjusting the resonant frequency point of the entire antenna to around 13.56Mhz through a matching circuit, the signal amplitude on the coil can be increased, which is beneficial to magnetic field radiation. Finally, the PCB coil sends it to the radio frequency IC card to write data.

[0075] The RFID IC card is used as a way for users to recharge the water extraction device. Users can recharge the water extraction device by placing the RFID IC card close to the card reader of the water extraction device. Once there is enough balance in the account, the user can control the operation of the DC motor connected to the cam by swiping the card or remotely controlling it through a mobile phone APP.

[0076] In this embodiment, multiple channels are used for recharging: CAT1 remote recharge, radio frequency IC card, LCD display QR code and mobile phone APP recharge. CAT1 remote recharge supports remote recharge, allowing users to inject funds into their accounts anytime and anywhere, no longer restricted by time and place. In addition, the water collection device also introduces radio frequency IC card and LCD Bluetooth short-distance recharge functions. Just bring the radio frequency IC card or mobile phone close to the water collection device to achieve fast recharge. No complicated operation is required, just stick it and use it, which is convenient and fast, making the recharge experience more diversified.

[0077] After each use, the water intake device will directly display the water consumption data, allowing customers to immediately grasp the water consumption information. No tedious operations are required, and no background viewing is required, which improves the convenience of the product. At the same time, the water intake device will also broadcast the water consumption data to the water user in real time to ensure that the water user will not miss any important information. Whether it is water volume, price or other details, it can be accurately and timely conveyed to the water user, realizing efficient and convenient management.

[0078] In this embodiment, through the setting of various sensors and modules, it is particularly important to be able to perform real-time and accurate fault monitoring of the water intake device, as well as timely and effective fault handling. This can not only ensure the continuity and stability of the water supply system, but also ensure that the production and living needs of the water users are met.

[0079] Although the above describes the specific implementation methods of the utility model in combination with the accompanying drawings, it is not intended to limit the scope of protection of the utility model. Technical personnel in the relevant field should understand that on the basis of the technical solution of the utility model, various modifications or deformations that can be made by technical personnel in this field without creative work are still within the scope of protection of the utility model.
