When the human hand 600 moves from the fifth position 750 shown in fig. 5B to the sixth position 760 shown in fig. 5C along the second setting direction 820, the temperature of the output water of the induction tap 900 increases to the maximum, and the whole number of the second light-emitting units 321 of the second light-emitting device 320 is turned on, i.e. the light-emitting area of the second light-emitting device 320 reaches the maximum. In contrast, when the human hand 600 moves from the sixth position 760 shown in fig. 5C to the fourth position 740 shown in fig. 5A, the second sensing device 220 senses that the human hand 600 moves to the other end along the second setting direction 820, and senses that the temperature of the output water of the faucet 900 decreases, the number of the second light emitting units 321 of the second light emitting device 320 near one end decreases, that is, the light emitting area of the second light emitting device 320 decreases toward the other end.

In summary, the sensing faucet of the present invention can adjust the flow rate of the output water and the light emitting area of the first light emitting device according to the movement of the object, such as a human hand, sensed by the first sensing device along the first setting direction, and adjust the temperature of the output water and the light emitting area of the second light emitting device according to the movement of the object, such as a human hand, sensed by the second sensing device along the second setting direction. In other words, the user can move the first and second sensors along the first and second setting directions by hand to control/change the flow and temperature of the output water of the sensor faucet, and the flow and temperature of the output water of the sensor faucet can be displayed by the first and second light-emitting devices. Therefore, the induction tap of the invention has simple and intuitive operation, clear and understandable operation state and better use convenience.

The flow rate and temperature of the output water can be adjusted by controlling the flow rate of the cold water and the hot water. More specifically, in the embodiment shown in fig. 6, the induction faucet 900 further includes a cold water flow control device 610, a hot water flow control device 620, and a control module 630. The cold water flow control device 610 controls the flow of cold water. The hot water flow control device 620 controls the flow of hot water. The cold water flow control device 610 and the hot water flow control device 620 may be valves, pumps, and other devices capable of controlling the flow rate of the fluid. The cold water flow control device 610 and the hot water flow control device 620 may be disposed inside or outside the body 100. The control module 630 is coupled to the first sensing device 210, the second sensing device 220, the first light emitting device 310, the second light emitting device 320, the cold water flow control device 610, and the hot water flow control device 620, respectively. The control module 630 may be a device including a circuit board, a processing unit, a storage unit, etc., and has functions of receiving, processing, storing, and sending signals.

The first sensing device 210 can sense the movement of the object along the first setting direction to generate a first sensing signal 421. The second sensing device 220 can sense the movement of the object along the second setting direction to generate a second sensing signal 422. The control module 600 generates a first cold water control signal 461, a first hot water control signal 462, and a first lighting control signal 463 according to the first sensing signal 421. The cold water flow control device 610 and the hot water flow control device 620 control the flow rates of the cold water and the hot water according to the first cold water control signal 461 and the first hot water control signal 462, respectively, to adjust the flow rate of the output water. The first light emitting device 310 adjusts a light emitting area of the first light emitting device 310 according to the first light emitting control signal 463. The control module 600 generates a second cold water control signal 464, a second hot water control signal 465 and a second light control signal 466 according to the second sensing signal 422. The cold water flow control device 610 and the hot water flow control device 620 respectively control the flow rates of the cold water and the hot water according to the second cold water control signal 464 and the second hot water control signal 465 to adjust the temperature of the output water. The second light emitting device 320 adjusts a light emitting area of the second light emitting device 320 according to the second light emitting control signal 466.

In various embodiments, the induction faucet of the present invention may be used in environments where only a cold water source line is available. More specifically, as shown in fig. 7A, in a different embodiment, the induction faucet 901 of the present invention includes a body 100, a first induction device 210, a second induction device 220, a first light-emitting device 310, and a second light-emitting device 320. The body 100 includes a cold water inlet 110 into which cold water flows and an outlet 130 from which output water flows. In this embodiment, the flow rate and temperature of the output water can be adjusted by controlling the flow rate of the cold water and heating the cold water, respectively. As shown in the embodiment of fig. 7B, the induction tap 901 further comprises a cold water flow control 611, a cold water heater 612, and a control module 631. The cold water flow control device 611 controls the flow of cold water. The cold water heating device 612 heats cold water. The control module 631 is respectively coupled to the first sensing device 210, the second sensing device 220, the first light emitting device 310, the second light emitting device 320, the cold water flow control device 611, and the cold water heating device 612.

The first sensing device 210 can sense the movement of the object along the first setting direction to generate a first sensing signal 421, and the second sensing device 220 can sense the movement of the object along the second setting direction to generate a second sensing signal 422. The control module 631 generates a flow control signal 471 and a first light emitting control signal 472 according to the first sensing signal 421, the cold water flow control device 611 controls the flow of the cold water according to the flow control signal 471 to adjust the flow of the output water, and the first light emitting device 310 adjusts the light emitting area of the first light emitting device 310 according to the first light emitting control signal 472. The control module 631 generates a heating control signal 473 and a second light-emitting control signal 474 according to the second sensing signal 422, and the cold water heating device 612 heats cold water according to the heating control signal 473 to adjust the temperature of the output water. The second light emitting device 320 adjusts a light emitting area of the second light emitting device 320 according to the second light emitting control signal 474.

As shown in the embodiment of fig. 2A, the body 100 has an extension axis 180, and the first arrangement direction 810 is parallel to the extension axis 180. The first disposing direction 810 and the second disposing direction 820 preferably have an angle θ. In the embodiment shown in FIG. 2A, the included angle θ is 90. In other words, the first sensing device 210 and the second sensing device 220 are disposed in a direction perpendicular to each other. Therefore, the interference or misjudgment of the first sensing device 210 and the second sensing device 220 on the sensing of the object movement can be reduced. More specifically, when the user moves along the first setting direction 810 with the hand of the first sensing device 210, the second sensing device 220 does not sense the movement of the object along the second setting direction 820, and therefore only the flow rate of the output water of the sensing faucet is changed, and the temperature is not changed. In contrast, when the user moves along the second setting direction 820 with the hand of the second sensing device 220, the first sensing device 210 does not sense the movement of the object along the first setting direction 810, and thus only the temperature of the output water of the sensing faucet is changed, but the flow rate is not changed. However, the first arrangement direction 810 and the second arrangement direction 820 may be arranged in the same direction in different embodiments as shown in fig. 8A based on manufacturing, design or use requirements. In addition, in different embodiments, the first sensing device 210 and the second sensing device 220 can be disposed at different positions. In a different embodiment shown in fig. 8B, the first sensing device 210 is disposed on the bottom surface 102 of the body 100. In a different embodiment shown in fig. 8C, the first sensing device 210 is disposed on the other side surface 103b of the body 100. In a different embodiment, as shown in fig. 8D, the second sensing device 220 is disposed on the end surface 104 of the body 100 near the outlet 130. On the other hand, the first sensing device 210 and the second sensing device 220 are preferably facing different directions, so as to further reduce the interference or misjudgment of the two on the sensing of the object movement.

In the above embodiments, the first light emitting device and the second light emitting device are both composed of a plurality of light emitting units arranged at intervals, that is, the light emitting areas are discontinuous. However, in various embodiments, the first and second light emitting devices may be continuous based on manufacturing, design, or usage requirements. Further, in the embodiment shown in fig. 9, the color of the light emitting area of the first light emitting device 316 of the induction faucet 906 is sequentially represented by rainbow seven primary colors of red, orange, yellow, green, blue, indigo, purple, etc. from the end near the outlet 130 to the end far away from the outlet 130. The colors of the light emitting region of the second light emitting device 326 are sequentially represented by seven primary colors, such as red, orange, yellow, green, blue, indigo, and violet, toward one end along the second arrangement direction 820. Therefore, the appearance can be improved, and the visual prompting effect is increased. In various embodiments, the color of the light emitting area of the first light emitting device 316 is also shown from the end near the outlet 130 toward the end far away from the outlet 130 by gradually changing the first color to the second color (e.g., from red to blue). The color of the light-emitting region of the second light-emitting device is displayed in such a manner that the first color gradually changes to the second color (for example, gradually changes from red to blue via purple) toward one end along the second arrangement direction 820.

In the embodiment shown in fig. 9, the sensing tap 906 further comprises a third sensing device 230 capable of sensing an object, and when the third sensing device 230 does not sense the object, the sensing tap 906 adjusts the flow rate of the output water to be zero. In other words, when the user's hand is away from the third sensing device 230 by a certain distance, indicating that the user has finished using the faucet 906, the output water can be automatically stopped to save the water. On the other hand, in one implementation, when the third sensing device 230 senses the object and the first sensing device 216 and the second sensing device 226 do not sense the movement of the object, the sensing faucet 906 adjusts the flow rate and the temperature of the output water to the preset flow rate and the preset temperature, respectively. Wherein, the preset flow and the preset temperature are preferably 50% and 38 ℃ of the maximum flow of the cold water respectively. On the other hand, the induction faucet may further be coupled to the control module at a location such as the outlet, inside the body, cold water inlet, hot water inlet, etc., where a temperature sensor senses the temperature for the control module to use as a reference for controlling the temperature of the output water.

Referring to the flowchart of fig. 10, the method for controlling an induction faucet according to the present invention includes the following steps.

In step 1000, the third sensing device senses the object.

In step 2100, when the third sensing device senses the object, the sensing faucet adjusts the flow rate and the temperature of the output water to a preset flow rate and a preset temperature, respectively.

Step 2200 is that the first sensor senses the movement of the object along the first setting direction, and adjusts the flow rate of the output water and the light emitting area of the first light emitting device.

2300, the second sensor senses the movement of the object along the second setting direction, and adjusts the temperature of the output water and the light emitting area of the second light emitting device.

Step 3000, when the third sensor device does not sense the object, the sensor faucet adjusts the flow of the output water to zero.
