[0003] Water monitoring is a common monitoring method for judging problems, the daily water consumption of old people living alone is obtained by water meter and other water consumption monitoring equipment, and the living state of old people living alone is judged according to the change of water consumption. But the conventional water meter and other water consumption monitoring equipment can only detect the total water consumption, and cannot monitor the water consumption of each water faucet respectively. CN201620546151.1 discloses a water faucet capable of automatically recording water consumption, which can detect the water consumption of water faucet and transmit data to mobile phone and other terminal equipment. But old people living alone have poor memory, may forget to turn off the water faucet, and may also have the situation that the water faucet is not completely closed. When forgetting to turn off the water faucet or the water faucet is not completely closed, the prior art cannot timely remind, resulting in waste of water resources. UTILITY MODEL CONTENT

[0004] The technical problem to be solved by the utility model is to provide a kind of intelligent monitoring water faucet, when water faucet continuously water exceeds certain time, remind, avoid waste of water resources.

[0005] To solve the above problems, the technical scheme adopted by the utility model is as follows: an intelligent monitoring water faucet, comprising a water inlet pipe, a monitoring seat and a water outlet pipe, a water passing channel is arranged in the monitoring seat, one end of the water passing channel is connected with the water inlet pipe, the other end of the water passing channel is connected with the water outlet pipe, a valve is arranged on the water inlet pipe or the water outlet pipe;

[0006] A microcontroller is arranged in the monitoring seat, a flow sensor is arranged in the water passing channel, the flow sensor is electrically connected with the microcontroller, and the microcontroller is connected with a remote terminal through a communication module;

[0007] The valve comprises a valve body, a valve core, a valve rod and an operating handle, the valve core is arranged in the valve body, one end of the valve rod is connected with the valve core, and the other end is connected with the operating handle;

[0008] The outer wall of the valve body is fixedly provided with a monitoring sleeve, the valve rod penetrates through the monitoring sleeve and is in gap cooperation with the monitoring sleeve, the inner wall of the monitoring sleeve is provided with a radially extending installation blind hole, the hole bottom of the installation blind hole is provided with a pressure sensor, the pressure sensor is electrically connected with a microcontroller; a measuring rod in sliding cooperation with the installation blind hole is arranged in the installation blind hole, a spring is arranged between one end of the measuring rod and the pressure sensor, and the other end of the measuring rod is provided with a wedge-shaped chuck; the side wall of the valve rod is provided with a clamping groove which is adapted to the wedge-shaped chuck in shape.

[0009] Further, the microcontroller is connected with an alarm.

[0010] Further, the alarm is an audible and light alarm arranged on the outer wall of the monitoring seat.

[0011] Further, the water outlet pipe is in rotary cooperation with the water passing channel.

[0012] Further, the communication module is a LoRa module.

[0013] Further, the elastic sleeve is arranged outside the operation handle.

[0014] Further, the water inlet pipe is a hose.

[0015] The utility model discloses a water faucet, which comprises a valve body, a valve rod, a water inlet pipe, a water outlet pipe, a water passing channel, a communication module, a microcontroller, a monitoring seat, a flow sensor, an alarm and an operation handle.

[0016] The flow sensor can also record the faucet opening and closing time, but when the valve of the faucet is not completely closed, the water flow is very small, and the flow sensor is difficult to accurately detect the small water flow, therefore, the valve is also reformed in the utility model. When the valve is in the closed state, the wedge-shaped clamping head is located in the inside of the clamping groove. The two side surfaces of the wedge-shaped clamping head are inclined surfaces, when the valve is opened, the wedge-shaped clamping head is pushed by the side wall of the clamping groove and moves towards the inside of the mounting blind hole, compresses the spring, the spring transmits the pressure to the pressure sensor, the pressure sensor generates a pressure signal and transmits the signal to the microcontroller. When the valve is closed, the clamping groove rotates to the initial position with the valve rod, the wedge-shaped clamping head enters the inside of the clamping groove again under the pushing of the spring, and the pressure received by the pressure sensor is reduced. The microcontroller judges the continuous water outlet time of the faucet according to the pressure sensor signal duration, and sends a signal to the remote terminal when the continuous water outlet time is greater than the set time. If the valve is not completely closed when the water is turned off, the clamping groove does not return to the initial position, the wedge-shaped clamping head is staggered with the clamping groove, and the wedge-shaped clamping head cannot return to the clamping groove. At this time, the flow sensor cannot detect the water flow, and the pressure sensor continues to be in a high pressure state, and the microcontroller can judge that the valve is not completely closed according to the signals of the flow sensor and the pressure sensor, and can send a signal to the remote terminal for prompting.

DETAILED DESCRIPTION

[0023] The utility model is further illustrated below in combination with the drawings and examples.

[0024] The intelligent monitoring faucet of the utility model, such as Figure 1 and Figure 2 As shown in the figure, comprising water inlet pipe 1, monitoring seat 2 and water outlet pipe 3, the water passage 4 is arranged in the monitoring seat 2, one end of the water passage 4 is connected with the water inlet pipe 1, the other end of the water passage 4 is connected with the water outlet pipe 3, and the valve is arranged on the water inlet pipe 1 or the water outlet pipe 3.

[0025] Among them, the water inlet pipe 1 is connected with the household water pipe, and is used for connecting the intelligent monitoring faucet as a whole into the water pipe. The water inlet pipe 1 can adopt a metal pipe, preferably a hose, such as a rubber pipe, which can be bent, and is more flexible during installation, reducing the installation difficulty. The monitoring seat 2 is used for monitoring the water consumption of each faucet. The water outlet pipe 3 is used for discharging tap water. The water passage 4 can be horizontally arranged, vertically arranged or in L shape.

[0026] The microcontroller 6 is arranged in the monitoring seat 2, and the microcontroller 6 is used for receiving and processing detection signals, and then transmitting data to the remote terminal 8. The microcontroller 6 can adopt the prior art, for example, it can be a chip of STM32 series. The flow sensor 5 is arranged in the water passage 4, and the flow sensor 5 is electrically connected with the microcontroller 6, and the microcontroller 6 is connected with the remote terminal 8 through the communication module 7. The flow sensor 5 is used for detecting the water flow through the water passage 4 and transmitting the detection signal to the microcontroller 6. The flow sensor 5 can adopt models such as WFK3000, WFK3004S. The communication module 7 can realize the communication between the microcontroller 6 and the remote terminal 8, and can adopt a LoRa module, the communication distance is long, and the model can be commonly used models such as E22-400T37S, E32-433T20S, E220-900T30S. The remote terminal 8 can be a mobile phone, a computer or the like, and is managed by the guardian or the community related management personnel.

[0027] When water is used normally, water flows out through the water inlet pipe 1, the water passage 4 and the water outlet pipe 3 in turn, the flow sensor 5 can detect the water flow through the water passage 4, and the microcontroller 6 transmits the detection result to the remote terminal 8 in real time, so as to obtain the water consumption of each time and the total water consumption per day, and the living condition of the old person living alone can be judged according to the water consumption. If an accident occurs, for example, all the faucets are not used for a long time, the guardian can visit the old person living alone to further confirm the condition of the old person living alone and timely handle the accident.

[0028] When the valve is opened, the water outlet pipe 3 discharges water, and when the valve is closed, the water outlet pipe 3 stops discharging water, but it is easy to forget to close or the valve is not completely closed, when the valve is not completely closed, the faucet will drip or discharge a small stream of water, because the water flow is very small, the flow sensor 5 is difficult to detect the water flow, so it is impossible to judge whether the faucet is completely closed through the flow sensor 5.

[0029] In order to accurately judge whether the faucet is completely closed, the utility model improves the valve, specifically, the improved valve includes a valve body 9, a valve core 10, a valve rod 11 and an operating handle 12, the valve core 10 is arranged inside the valve body 9, one end of the valve rod 11 is connected with the valve core 10, and the other end is connected with the operating handle 12. The internal structure of the valve body 9, the valve core 10 and the operating handle 12 can adopt the prior art, the operating handle 12 drives the valve rod 11 and the valve core 10 to rotate, that is, the valve is opened, and the water discharge amount can be controlled by controlling the rotation angle of the operating handle 12.

[0030] The outer wall of the valve body 9 is fixedly provided with a monitoring sleeve 13, the valve rod 11 penetrates through the monitoring sleeve 13 and is in gap cooperation with the monitoring sleeve 13, a radially extending installation blind hole 14 is arranged on the inner wall of the monitoring sleeve 13, the installation blind hole 14 is a rectangular hole, a pressure sensor 15 is arranged on the hole bottom of the installation blind hole 14, and the pressure sensor 15 is electrically connected with the microcontroller 6; a measuring rod 16 in sliding cooperation with the installation blind hole 14 is arranged in the installation blind hole 14, a spring 17 is arranged between one end of the measuring rod 16 and the pressure sensor 15, and a wedge-shaped chuck 18 is arranged at the other end of the measuring rod 16; and a clamping groove 19 matched with the wedge-shaped chuck 18 in shape is arranged on the side wall of the valve rod 11.

[0031] When the valve is in the closed state, the wedge-shaped chuck 18 is clamped into the clamping groove 19. The two side walls of the wedge-shaped chuck 18 are inclined surfaces, the clamping groove 19 is a V-shaped groove, and the wedge-shaped chuck 18 can fill the clamping groove 19 after being clamped into the clamping groove 19. When the valve rod 11 rotates, the side wall of the clamping groove 19 will push the wedge-shaped chuck 18 to move axially, so that the whole measuring rod 16 moves towards the inside of the installation blind hole 14, the spring 17 is extruded, the elastic force of the spring 17 is transmitted to the pressure sensor 15, and the pressure sensor 15 transmits the pressure signal to the microcontroller 6. When the wedge-shaped chuck 18 completely separates from the clamping groove 19, the tip of the wedge-shaped chuck 18 is close to the outer wall of the valve rod 11, and the pressure received by the pressure sensor 15 remains stable.

[0032] When the valve is closed, the clamping groove 19 returns to the initial position along with the valve rod 11, the measuring rod 16 moves towards the direction of the clamping groove 19 under the action of the spring 17, so that the wedge-shaped chuck 18 enters the clamping groove 19 again. If the valve is not completely closed when the valve is closed, that is, the clamping groove 19 does not completely return to the initial position, at this time, there are two cases, the first case is as follows Figure 3As shown, the wedge-shaped clamping head 18 also abuts against the outer wall of the valve stem 11, and the tip of the wedge-shaped clamping head 18 does not extend into the clamping groove 19. At this time, the pressure sensor 15 still bears a high pressure, and the detected pressure value is high, and the flow sensor 5 does not detect water flow or detects very small water flow. Therefore, the microcontroller 6 determines, according to the detection results of the flow sensor 5 and the pressure sensor 15, that the valve is not completely closed if the detection result of the pressure sensor 15 is the same as that in normal use, but the water flow detected by the flow sensor 5 is 0 or very small, and transmits the data to the remote terminal 8 and sends a prompt message to the remote terminal 8.

[0033] The second case is shown in Fig. 3. Figure 4 As shown, the clamping groove 19 does not return to the initial position completely, but the tip of the wedge-shaped clamping head 18 can extend into the clamping groove 19. At this time, the measuring rod 16 moves axially under the pushing of the spring 17, and drives the wedge-shaped clamping head 18 into the clamping groove 19. When the wedge-shaped clamping head 18 enters the clamping groove 19, the wedge-shaped clamping head 18 contacts the side wall of the clamping groove 19 and automatically pushes the valve stem 11 to rotate, so that the clamping groove 19 returns to the initial position completely, and the valve is completely closed. It can be seen that the utility model also has the function of automatically correcting the position of the clamping groove 19 to make the valve completely closed.

[0034] When the flow sensor 5 detects that the water flow is stable and the continuous water discharge time exceeds the set value, it may be that the old person living alone forgets to turn off the faucet. The microcontroller 6 is connected with an alarm 20. When the microcontroller 6 determines that the water is forgotten to be turned off or the valve is not completely closed, the microcontroller 6 controls the alarm 20 to issue an alarm. The alarm 20 can be various alarm elements in the prior art. In order to improve the alarm effect, the alarm 20 is an audible and visual alarm arranged on the outer wall of the monitoring seat 2.

[0035] The water outlet pipe 3 is rotationally connected with the water passage 4. The water outlet pipe 3 can be in an inverted L shape. The position of the water outlet of the water outlet pipe 3 can be changed by rotating the water outlet pipe 3, and the use is more flexible.

[0036] The operation handle 12 is usually made of metal material and has high hardness, and is relatively cold in winter. Therefore, an elastic sleeve 22 is arranged outside the operation handle 12. The elastic sleeve 22 can be a waterproof rubber sleeve or the like, so as to avoid frostbite when operating.

[0037] The above only describes preferred embodiments of the utility model and is not used to limit the utility model. For those skilled in the art, the utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
