Technical Field

[0001] The present invention is an intelligent induction faucet and its control method, belonging to the field of faucets. Background Art

[0002] With the continuous development of technology, smart home devices have gradually become an important part of modern families. In areas with frequent water use such as kitchens and bathrooms, the traditional faucet control methods have gradually revealed many deficiencies. For example, traditional faucets require users to manually turn them on and off, which is not only inconvenient to operate but also causes waste of water resources when forgotten to be turned off. In addition, although some existing induction faucets have achieved the function of automatic water discharge, they often lack the intelligent perception ability of the external environment and cannot automatically adjust the working state according to light conditions or user habits, resulting in energy waste and poor user experience.

[0003] To solve the above problems, the present invention proposes an intelligent induction faucet and its control method. This method combines photosensitive sensor technology and advanced control methods, can automatically adjust the state of the induction unit according to the external light intensity, and at the same time learn the user's usage habits to achieve more intelligent, energy-saving and convenient faucet control.

[0023] By reading the detailed description of the non-restrictive embodiments with reference to the following drawings, other features, objects and advantages of the present invention will become more obvious:

[0024] Figure 1 It is a schematic structural diagram of an intelligent induction faucet according to the present invention. Detailed Embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] An intelligent induction faucet mainly includes a faucet body, and an induction unit 3, an electronic switch, a control unit and a photosensitive sensor 2 arranged on the faucet body. Relying on the collaborative work of these components, the function of automatically adjusting the state of the induction unit 3 according to the external light intensity is realized.

[0027] The photosensitive sensor 2 is used to obtain the external light intensity in real time, and sends a signal to the control unit according to the change in the light intensity. When the external light intensity is greater than or equal to a preset first threshold, after receiving the signal, the control unit activates the induction unit 3 to make it in a standby state to respond to the approach or contact of the user. Combining the photosensitive sensing technology with the induction control of the faucet realizes the function of automatically adjusting the working state of the faucet according to the light conditions.

[0028] The induction unit 3 includes a touch - type induction unit and an inductive induction unit, providing multiple user interaction methods. Users can trigger the water outlet function of the faucet by touching or approaching the induction unit 3. Specifically, in one embodiment, a highly sensitive capacitive touch - type induction unit is adopted, and the touch area is designed above the faucet body (refer to Figure 1 ), and the user can activate it by touching the induction unit 3 with their hand. In another embodiment, an infrared sensor inductive induction element is adopted. When the user approaches, an induction signal is triggered.

[0029] The control unit also has the function of learning the user's usage habits and can obtain the user's usage time period within 24 hours. When the light intensity meets the conditions and is within the user's common usage time period, the induction unit 3 will be activated. Through machine - learning technology, the faucet can automatically adjust its working state according to the user's personal habits, realizing more personalized services.

[0030] When the induction unit 3 is in the sleep state, if the user's approach causes a significant decrease in the light intensity detected by the photosensitive sensor 2, the induction unit 3 will be temporarily activated. This transient activation state allows the user to wake up the faucet under specific conditions without reaching the conventional light - intensity threshold. Triggering the transient activation of the faucet through the change in light intensity provides a more flexible and convenient usage method for the user.

[0031] Furthermore, the photosensitive sensor 2 is not only used to detect the external light intensity but also to detect the change in light - intensity decrease caused by the user's approach or contact. Refer to Figure 1 , one of the photosensitive sensors 2 is arranged on the front side of the faucet body 1. When the user approaches, the user's figure blocks the front side of the faucet body 1, resulting in a change in the light intensity on the front side of the faucet body 1. This change is used to trigger the transient activation state of the induction unit 3, thereby allowing the user to wake up the faucet under specific conditions. The basic function of the photosensitive sensor 2 is extended, enabling the photosensitive sensor 2 to not only be used to judge the first threshold but also to detect whether a user approaches or contacts, realizing a more accurate and timely response to the user's actions in different environments.

[0032] Furthermore, the intelligent control algorithm in the control unit is optimized through existing learning AI to more accurately learn the user's usage habits and predict future usage time periods. This predictive ability enables the faucet to remain activated during the time period when the user is most likely to use it, thereby improving the usability and energy - saving performance of the device.

[0033] Furthermore, in order to provide a better user experience, the user interface of the faucet has been improved in one of the embodiments. For example, a display screen is added to display information such as the current working status and water flow rate. In addition, a voice prompt function is provided to give instant feedback when the user operates the faucet. These improvements enhance the usability of the device and user satisfaction. The user interface is synchronized with the electronic switch so that the user interface is turned on when the electronic switch is turned on.

[0034] Embodiment 1

[0035] Intelligent induction faucet control method based on a photosensitive sensor 2 and user behavior: The intelligent induction faucet includes a faucet body; an induction unit 3, an electronic switch, a control unit, and a photosensitive sensor 2 provided on the upper side of the faucet body; The control method includes:

[0036] S1, Set the initial parameters of the photosensitive sensor 2, including a first threshold value, which is used to determine whether the external light is bright enough to activate the induction unit 3; then obtain the external light intensity in real time through the photosensitive sensor 2.

[0037] S2, Compare the real-time monitored light intensity with the preset first threshold value to determine whether the external light intensity is greater than or equal to the first threshold value. If so, send a signal to the control unit and control the induction unit 3 to be in an active state and enter S3. This indicates that if the light intensity is greater than or equal to the first threshold value, it means that the current ambient light is sufficient, and the induction unit 3 will continue to monitor the user's behavior. Otherwise, control the induction unit 3 to be in a sleep state to reduce unnecessary energy consumption.

[0038] S3, When the ambient light meets the conditions, the induction unit 3 is in a standby state, ready to respond to the user's behavior. When the user approaches or touches, the control unit obtains the signal generated by the induction unit 3 and controls the electronic switch to work to discharge water. When the user moves away from the induction unit 3, the control unit obtains the signal sent by the induction unit 3 again and delays controlling the electronic switch to close.

[0039] Specifically, when the light conditions are met, the induction unit 3 enters a standby state, ready to respond to the user's approaching or touching behavior. Once the user approaches or touches the induction unit 3, the system will immediately control the electronic switch to work, causing the faucet to discharge water. When the user moves away from the induction unit 3, the faucet will automatically close after a delay.

[0040] In addition, the control method of this embodiment further includes a learning module for further learning the user's usage habits and obtaining the corresponding usage time periods of the user within 24 hours, so as to record and analyze the user's usage habits for more accurate prediction of the user's usage time periods in subsequent use.

[0041] And in step S2, when determining whether the ambient light intensity is greater than or equal to the first threshold, if so, a signal is sent to the control unit and the sensing unit 3 is controlled to be in an active state and enter S3; otherwise, the sensing unit 3 is controlled to be in a sleep state, which specifically includes:

[0042] S21, the control unit further controls that when the ambient light intensity is greater than or equal to the first threshold and within the corresponding time period, a signal is sent to the control unit and the sensing unit 3 is controlled to be in an active state; otherwise, the sensing unit 3 is controlled to be in a sleep state.

[0043] This helps to improve the intelligence level of the device and user satisfaction. Since the lighting time in a day is basically much longer than the usage time, except during the usage time, during other lighting times, the control unit is in a sleep state. And within the predicted usage period, even if the light conditions do not fully reach the activation threshold, the control unit will activate the sensing unit 3 in advance to enhance the user experience.

[0044] Embodiment 2

[0045] Intelligent sensing faucet control method in a transient activation state: The same as in Embodiment 1, a first threshold is set, and a photosensitive sensor 2 is additionally provided in front of the faucet body 1. When a user approaches the faucet body 1, the light intensity detected by the photosensitive sensor 2 in front of the faucet body 1 suddenly drops, and the control unit will place the sensing unit 3 in a transient activation state;

[0046] When the sensing unit 3 is in a sleep state, and when the photosensitive sensor 2 obtains a sudden drop change in the ambient light intensity due to the user approaching or contacting, a signal is sent to the control unit and the sensing unit 3 is controlled to be in a transient activation state.

[0047] When the user approaches or contacts the sensing unit 3 in the transient activation state, the sensing unit 3 further controls the electronic switch to discharge water. When the user moves away from the photosensitive sensor 2 and causes an increase in light intensity, the control unit further controls the electronic switch to close and at the same time controls the sensing unit 3 to be in a sleep state.

[0048] Specifically: User response in the transient activation state:

[0049] In the transient activation state, if the user further contacts the sensing unit 3, the faucet will immediately discharge water.

[0050] If the user does not perform further operations within a certain activation time (the activation time can be adjusted through the user interface), the sensing unit 3 will automatically return to the sleep state to save energy.
