Description

Technical Field

[0002] As people's demands for quality of life become higher and higher, faucets have basically become an indispensable daily necessity.

[0003] The water inlet of the faucet can be connected to a water source. The water supplied by the water source can enter the faucet through the water inlet and then flow out through the water outlet of the faucet. At the same time, existing faucets are equipped with intelligent accessories such as sensors to realize different functions, such as sensing the presence of a limb or object approaching before discharging water. At the same time, flow control is also indispensable for faucets. An automatic throttle valve disclosed in application number CN202122224093.4 includes: a housing, a valve core, a motor, a flow sensor rotor, a first Hall element, a second Hall element and a positioning magnet. The housing is provided with an inlet pipe, an outlet pipe and a valve core cavity. When in use, the moving plate is driven to rotate by the motor, and the output shaft of the motor drives the positioning magnet to rotate during the rotation process, and the second Hall element can sense the position of the positioning magnet, thereby determining the rotation amplitude of the motor output shaft. Under normal circumstances, the first Hall element cooperates with the flow sensor rotor to obtain the water flow in the water inlet pipe in real time, thereby controlling the time for the motor to open the valve core as needed.

[0004] Existing faucets can automatically adjust water flow according to distance by using distance sensors and automatic throttle valves. However, the intelligence of faucets is accompanied by the stacking and integration of electrical components, which can easily lead to high failure and maintenance rates. At the same time, the judgment logic of faucets in the existing technology is that when the human body is far away from the water outlet of the faucet, a larger water output is required, and when the human body is close to the water outlet of the faucet, a smaller water output is required, which can cause the human body to be easily splashed.

[0028] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, connecting, etc. should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0029] refer to Figure 1As shown, the water flow adaptive regulating induction faucet according to the embodiment of the utility model includes a water inlet end (not shown in the figure), a water outlet end 100 and a control pipeline connected between the water inlet end and the water outlet end 100, the control pipeline includes a remote water outlet pipeline 210 with a smaller water flow rate and a proximal water outlet pipeline 220 with a larger water flow rate, the remote water outlet pipeline 210 and the proximal water outlet pipeline 220 are respectively connected to the water inlet end and the water outlet end 100 through a tee (not shown in the figure), the remote water outlet pipeline 210 is connected to the remote controller 230, the proximal water outlet pipeline 220 is connected to the proximal controller 240, the water outlet end 100 is connected to a distance sensor 250, and the distance sensor 250 is electrically connected to the remote controller 230 and the remote controller 230 respectively;

[0030] When the object is at a position relatively far away from the water outlet 100, the distance sensor 250 controls the near-end controller 240 to be disconnected and the far-end controller 230 to be turned on;

[0031] When the object is located relatively close to the water outlet 100 , the distance sensor 250 controls the remote controller 230 to be disconnected and the near controller 240 to be connected.

[0032] The water flow adaptively adjustable induction faucet according to the embodiment of the utility model has at least the following beneficial effects: the distance between the limb or object and the water outlet 100 is sensed by the distance sensor 250. When the object is relatively far away from the water outlet 100, the distance sensor 250 controls the proximal controller 240 to disconnect and the distal controller 230 to turn on. At this time, the distal water outlet pipe 210 is turned on, and the water flow of the water outlet 100 is small, so that there is no large splashing range when it hits the object at a higher distance, so that splashing will not occur. When the user needs a larger water flow, the object is moved closer to the water outlet 100, and the distance sensor 250 controls the distal controller 230 to disconnect and the proximal controller 240 to turn on. At this time, the proximal water outlet pipe 220 is turned on, and the water flow of the water outlet 100 is large, so that the user's needs can be met.

[0033] In some specific embodiments of the present utility model, it may also have the following additional technical features: a constant flow device is provided on the remote water outlet pipeline 210 .

[0034] refer to Figure 3As shown, specifically, the constant flow device includes a valve body 310 and an inlet 311 and an outlet 312 opened on the valve body 310, and a first flow limiting plate 320 and a second flow limiting plate 330 are sequentially arranged in the valve body 310 along the water flow direction, the second flow limiting plate 330 is fixedly connected to the valve body 310, and the first flow limiting plate 320 is movably connected to the valve body 310. The first flow limiting plate 320 is provided with a water outlet 321, and a flow limiting column 331 is arranged on the second flow limiting plate corresponding to the water outlet 321, the end of the flow limiting column 331 facing the water outlet 321 is a cone structure, and a plurality of drainage holes 332 are arranged around the circumference of the flow limiting column 331. By setting a constant flow device, when the water pressure in the valve body 310 becomes high, the first flow limiting plate 320 will be close to the inner wall of the valve body 310 and move toward the second flow limiting plate 330 under the action of high water pressure, and the water outlet 321 will be close to the flow limiting column 331, thereby reducing the water outlet area and controlling the flow rate; when the water pressure decreases, the first flow limiting plate 320 will move back due to the reduction in water pressure, thereby increasing the water outlet area and increasing the flow rate, which can effectively control the water output, and a reasonable water output can be obtained regardless of high or low water pressure. The water outlet 321 is preferably arranged at the center of the first flow limiting plate 320. When the first flow limiting plate 320 moves, the water outlet 321 at the center position will balance the pressure of the first flow limiting plate 320 as a whole, so that it will not tilt, making the movement smoother, thereby improving the sensitivity of water flow control. At the same time, the multiple drainage holes 332 arranged around it help to divert the water flow, so that the water outlet pressure is relieved.

[0035] In some specific embodiments of the utility model, it may also have the following additional technical features: a pressure relief groove 336 is provided on one surface of the second flow limiting plate 330 close to the water outlet 100, and the projection of the drain port is located in the pressure relief groove 336 when viewed from the water flow direction. When the water flows out of the drain port and enters the pressure relief groove 336, the space becomes larger rapidly, which is conducive to greatly reducing the water pressure, thereby making the water discharge more moderate.

[0036] In some specific embodiments of the utility model, the following additional technical features may be provided: an annular baffle 333 is provided on the second flow limiting piece 330 around the flow limiting column 331, the annular baffle 333 is further away from the flow limiting column 331 than the drainage hole 332, and an annular groove 322 is provided on the first flow limiting piece 320 at a position corresponding to the annular baffle 333. The annular baffle 333 is matched with the annular groove 322, so that the first flow limiting piece 320 and the second flow limiting piece 330 can be assembled and combined conveniently.

[0037] In some specific embodiments of the utility model, it may also have the following additional technical features: a plurality of notches 334 are spaced apart on the annular baffle 333, and the annular groove 322 is connected with the inlet 311 and the outlet 312 through the notches 334. Specifically, the outermost end of the annular groove 322 abuts against the inner wall of the valve body 310, and the size of the annular baffle 333 is smaller than the size of the annular groove 322. At this time, the space between the annular baffle 333 and the inner wall of the valve body 310 forms a buffer zone 335. When the water flow pressure is too high, the water flow entering from the inlet 311 cannot be immediately discharged by the drain hole 332 after passing through the water outlet 321, so that part of the water flow passes through the notch 334 and flows into the buffer zone 335. When the amount of water in the buffer zone 335 increases, the first flow limiting plate 320 will be supported and moved away from the second flow limiting plate 330. At this time, the water outlet 321 is away from the flow limiting column 331, thereby increasing the water outlet area and the flow rate, thereby avoiding the situation where the constant flow device is damaged due to excessive water flow pressure.

[0038] In some specific embodiments of the utility model, it may also have the following additional technical features: a return spring 340 is connected between the water outlet 321 and the flow limiting column 331, and the return spring 340 is arranged around the flow limiting column 331. The return spring 340 can further control the stability of the water flow.

[0039] In some specific embodiments of the present invention, it may also have the following additional technical features: the remote controller 230 and the proximal controller 240 are both solenoid valves.

[0040] refer to Figure 2 As shown, in some specific embodiments of the utility model, it may also have the following additional technical features: a water outlet fixture 400 is provided on the water outlet end 100, the distance sensor 250 is connected to the water outlet fixture 400, and a water outlet 410 for connecting to the outside and controlling the pipeline is opened on the water outlet fixture 400.

[0041] In some specific embodiments of the present invention, it may also have the following additional technical features: the distance sensor 250 is an infrared distance measuring sensor.

[0042] In some specific embodiments of the present invention, it may also have the following additional technical features: the distance sensor 250 is an ultrasonic distance sensor 250 .

[0043] In some specific embodiments of the utility model, the utility model may also have the following additional technical features: a proximity sensor (not shown in the figure) is also provided on the water outlet 100, and the proximity sensor is connected between the distance sensor 250 and the power supply. The proximity sensor is provided to sense whether a human body is close to the faucet, and the distance sensor 250 is turned on when someone is close, thereby saving energy.

[0044] It should be noted that the solenoid valve, infrared ranging sensor, ultrasonic distance sensor 250 and proximity sensor can all be obtained by consulting reference books to obtain corresponding models and available on the market according to the actual parameters required. They are common technical solutions known in the art, and their specific working principles and structures will not be repeated here.

[0045] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
