[0053] Please refer to Figure 1 and Figure 2, this embodiment provides a faucet with intelligent water outlet, which includes a body, an infrared image sensor 5, a control module 3, a voice module 4 and a pressure sensor 6; the body includes a water outlet 1 and a switch valve 2 for controlling the opening and closing of the water outlet 1, and the control module 3 is electrically connected to the switch valve 2, the infrared image sensor 5, the voice module 4 and the pressure sensor 6 respectively; the pressure sensor 6 is arranged above the body; the infrared image sensor 5 is used to collect the image of the occluder 8 below the water outlet 1 when it detects that the area below the water outlet 1 is blocked by an object; the control module 3 is used to receive the image collected by the infrared image sensor 5, identify the image to judge the type of the occluder 8, and send corresponding control signals to the switch valve 2 or the voice module 4 according to the type of the occluder 8; specifically, when the control module 3 determines that the type of the occluder 8 is a preset type, it sends a first control signal to the switch valve 2 to control the switch valve 2 to open; when the control module 3 determines that the type of the occluder 8 is other types, it sends a second control signal to the switch valve 2 to control the switch valve 2 to remain closed; when the control module 3 cannot determine the type of the occluder 8, it sends a third control signal to the voice module 4; the voice module 4 is used to receive the third control signal and send out a voice prompt message; the voice prompt message is used to prompt the user to perform a water outlet operation action within a predetermined time; the pressure sensor 6 is used to collect the pressure signal input by the user within a predetermined time and send the pressure signal to the control module 3; the control module 3 is used to control the switch valve 2 to open when it determines that the change of the pressure signal collected by the pressure sensor 6 matches the change of the pressure signal corresponding to the water outlet operation action; if not, it controls the switch valve 2 to close.
[0054] The body includes a water outlet 1 and a switch valve 2 for controlling the opening and closing of the water outlet 1. The switch valve 2 can be a ball valve. In this embodiment, it is preferably to use a built-in switch valve 2 without a corresponding handle for the switch valve 2, so as to avoid the waste of water resources caused by malicious opening of the faucet by humans, and at the same time, it is also convenient for the control module 3 to perform unified control. The infrared image sensor 5 is arranged at the water outlet 1, used to collect the image of the occluder 8 below the water outlet 1 and transmit it to the control module 3. The control module 3 can be integrated externally to avoid water splashing onto the control module 3 and causing damage; the voice module 4 is preferably arranged near the water outlet 1 to facilitate the user to understand the voice content and make corresponding actions. The pressure sensor 6 is arranged above the body, preferably near the water outlet 1, to facilitate the user to operate.
[0055] The control module 3 is used to identify the type of the occlusion 8. The identification process specifically includes three cases: The first case: When the control module 3 determines that the type of the occlusion 8 is a preset type, a first control signal is sent to the switching valve 2. The preset type refers to the image of a human hand, specifically including various gesture diagrams of human hands, which are stored in the control module 3. By comparing the image of the occlusion 8 with the image of the human hand, it is judged whether it is a human hand. If it is determined to be a human hand, the switching valve 2 is controlled to open, and water flows out from the water outlet 1. The second case: When the control module 3 determines that the type of the occlusion 8 is other types, and the other types refer to the situation where the image of the occlusion 8 significantly does not conform to the gesture and structure of the human hand, a second control signal is sent to the switching valve 2 to control the switching valve 2 to remain in the closed state. For example, if the occlusion 8 is obviously a square object or in the shape of an insect, etc., the control module 3 will send a second control signal to the switching valve 2 to make the switching valve 2 remain in the closed state.
[0056] The third case: When the control module 3 cannot determine the type of the occlusion 8, and this hand gesture diagram does not appear in the collected human hand gesture diagrams, but this part of the occlusion 8 is relatively similar to the human hand structure. For example, for a person with a disability in the hand, then the control module 3 will send a third control signal to the voice module 4. After receiving the third control signal, the voice module 4 will correspondingly issue a voice prompt message, and the voice prompt message is used to prompt the user to perform a water outlet action within a predetermined time. For example, the voice module 4 stores the voice prompt content: "Please press the faucet." Then when the voice module 4 receives the third control signal from the control module 3, the above voice prompt will be issued. If there is indeed a user who needs to wash hands, then the user will press the faucet according to the voice prompt. If there is no user (a small animal or an insect) or the user has no need to wash hands, the action shown in the voice prompt will not be performed, further avoiding the situation where the existing water-saving faucet has water flowing out when there is an occlusion 8.
[0057] The pressure sensor 6 is arranged above the faucet body. When the user presses the faucet, the pressure sensor 6 will sense the pressure signal input by the user and send it to the control module 3. A pressure change curve is pre-input in the control module 3. Only when the pressure change curve sent by the pressure sensor 6 matches the pre-input pressure change curve, the control module 3 will open the switching valve 2. Otherwise, the control module 3 controls the switching valve 2 to close. This can effectively avoid the situation where the faucet automatically discharges water due to incorrect user operations, and further reduces the risk of waste of water resources. In some preferred embodiments, an indicator light is also added to the pressure sensor 6. When the user presses the faucet, the indicator light lights up, indicating a successful press; or, after the voice prompt ends, the indicator light on the pressure sensor 6 lights up correspondingly, indicating that the user needs to press the position corresponding to the pressure sensor 6, which is the correct operation step. When the user presses successfully, the indicator light changes color or dims, indicating a successful press.
[0058] As a preferred embodiment, the voice module 4 prompts the user to perform a water outlet operation action within a preset time, and the pressure sensor 6 is used to receive the pressure change value within the preset time, so as to avoid the user performing the water outlet operation for too long, thereby affecting the judgment of the control module 3 on the water outlet operation.
[0059] By setting the infrared image sensor 5, the object 8 below the water outlet 1 is collected and transmitted to the control module 3, which is then identified by the control module 3 and different instructions are sent according to the judgment result to control the opening and closing of the switching valve 2. During this identification process, when it is determined that the type of the object 8 does not conform to the preset type, the switching valve 2 is kept in the closed state. At the same time, the voice module 4 and the pressure sensor 6 are added to prompt the user to perform corresponding actions to achieve the opening action of the switching valve 2, further avoiding the state of the faucet being accidentally opened when blocked by insects or other animals or objects, and reducing the waste of water resources.
[0060] In some embodiments, the faucet further includes a distance measuring sensor, which is electrically connected to the control module 3; when the control module 3 determines that the type of the object 8 is the preset type, the distance measuring sensor is used to measure the distance between the water outlet 1 and the object 8 below; the control module 3 is used to judge whether the distance transmitted by the distance measuring sensor is within the preset distance range. If so, the control module 3 continues to control the opening of the switching valve 2; otherwise, the control module 3 controls the closing of the switching valve 2. The distance measuring sensor is arranged at the water outlet 1 of the faucet, and the distance measuring sensor can measure the distance between the object 8 below the water outlet 1 and the water outlet 1. Optionally, the preset distance can be reasonably set according to the position of the faucet and the height from the washbasin. When the type of the object 8 is identified as belonging to the preset type, it is further determined whether the distance between the object 8 detected by the distance measuring sensor and the water outlet 1 is within the preset distance range. If it is within the preset distance range, the control module 3 controls the opening of the switching valve 2. If it is not within the preset distance range, the control module 3 controls the closing of the switching valve 2. This method can standardize the user's handwashing posture. When the user maintains a certain distance from the water outlet 1, the handwashing efficiency can be improved (being too close or too far from the water outlet 1 will make the handwashing not comprehensive enough). At the same time, it avoids the user placing the object at any distance below the water outlet 1, resulting in the switching valve 2 always being in the open state and causing waste of water resources.
[0061] In some embodiments, the faucet further includes a timer, which is electrically connected to the control module 3; the timer is used to count the duration of the object blocking below the water outlet 1 and the time interval between the start time point of the current block and the end time point of the previous block; the control module 3 is used to control the closing of the switching valve 2 when the duration or time interval output by the timer is less than the preset time interval.
[0062] To avoid malicious or accidental operations by users, when the control module 3 determines that the type of the occluder 8 is a preset type, the control module 3 controls the opening of the switching valve 2. At the same time, the timer can count the duration of the object occlusion below the water outlet 1, and the time interval between the start time point of the current occlusion and the end time point of the previous occlusion. If the duration or the time interval is less than the preset time interval, the control module 3 controls the closing of the switching valve 2. The above text can be understood in combination with specific embodiments: In some malicious operation scenarios, there is a situation where the occluder 8 repeatedly moves into and out of the area below the water outlet 1. In this case, the duration of the occluder 8 below the water outlet 1 is less than 3 s, and the interval time is less than 2 s. Then the control module 3 controls the closing of the switching valve 2 to avoid water discharge in this case and cause waste of water resources.
[0063] By adding a timer, the duration of the occluder 8 and the interval time between two hand washings can be counted and sent to the control module 3 for judgment, effectively avoiding the phenomenon of water discharge in the case of non-hand washing requirements and reducing the waste of water resources.
[0064] In some embodiments, the faucet further includes a random number generator and a prompt information storage module; the prompt information storage module is used to store the corresponding relationship between multiple prompt information and identification information; the random number generator is used to generate a random number; the value of the random number is one of the identification information sets; the control module 3 is used to retrieve the prompt information corresponding to the generated random number according to the generated random number and control the voice module 4 to send out the corresponding prompt information.
[0065] When the control module 3 cannot determine the type of the occluder 8, a third control information is sent to the voice module 4. At the same time, the third control information is also sent to the random number generator. Through the random number generated by the random number generator, the prompt information corresponding to the random number is matched in the prompt information storage module and sent to the voice module 4, and the voice module 4 is instructed to send out the corresponding prompt information, so as to instruct the user to perform the corresponding water discharge operation action.
[0066] The random number generator is used to generate random numbers. The value of the random number is one of the identification information set. The prompt information corresponds one-to-one with the identification information and is stored in the prompt information storage module. For example, the random number generator can randomly select a number between 0 and 9 as the random number. The identification information corresponds to 0-9, and different prompt information is stored for each of the 10 numbers: 1 - "Please long-press the faucet for 3 seconds"; 2 - "Please short-press the faucet 3 times", 3 - "Please short-press the faucet 2 times"... and so on. Then, when the number generated by the random number is 3, the corresponding prompt information "Please short-press the faucet 2 times" in the prompt information storage module is sent by the control module 3 to the voice module 4, and the voice module 4 plays the prompt information to ask the user to perform the corresponding operation within a predetermined time. When the control module 3 receives the pressure change curve corresponding to the operation, it will control the opening of the switch valve 2. The above embodiment can further prevent users from making misoperations on the faucet. At the same time, since the corresponding prompt information is different each time, it can increase the recognition of the opening methods of each faucet and prevent users from opening multiple faucets simultaneously, thus avoiding waste of water resources.
[0067] Please refer to Figure 3 , this embodiment also provides an intelligent water outlet system, including a faucet and a human portrait tracking camera 7. The faucet is the faucet described above; the human portrait tracking camera 7 is used to capture the regional image where the faucet is located and identify the human portrait information in the regional image; the control module 3 is also used to control the switch valve 2 to close when there is no human portrait information in the regional image.
[0068] The human portrait tracking camera 7 is used to capture the regional image where the faucet is located. The human portrait tracking camera 7 can be set according to the actual application scenario. When there are multiple faucets, one or more human portrait tracking cameras 7 can be set. When there is only one human portrait tracking camera 7, the shooting range should cover the entire area where the faucets are located. When there is no human portrait information in the regional image where the faucet is located, the control switch valve 2 is closed to avoid misoperations of the faucet caused by non-human hand blocking objects 8 such as bugs or small animals, resulting in the switch valve 2 remaining in the open state; and, the control module 3 controls the switch valve 2 to remain closed when there is no one in the area, further avoiding waste of water resources in the case where the user leaves directly after washing hands and the switch valve 2 is not closed in time.
[0069] Please refer to Figure 4 , this embodiment also provides a method for intelligent water outlet of a faucet. The method is applied to the faucet described above; the method includes the following steps:
[0070] S10. When the infrared image sensor detects that the area below the water outlet is blocked by an object, it collects an image of the blocking object below the water outlet;
[0071] S20. The control module receives the image collected by the infrared image sensor, identifies the image to determine the type of the occlusion, and sends a corresponding control signal to the switching valve or the voice module according to the type of the occlusion. Specifically, when the control module determines that the type of the occlusion is a preset type, it sends a first control signal to the switching valve to control the opening of the switching valve; when the control module determines that the type of the occlusion is other types, it sends a second control signal to the switching valve to control the switching valve to remain in the closed state; when the control module cannot determine the type of the occlusion, it sends a third control signal to the voice module.
[0072] S30. The voice module receives the third control signal and issues a voice prompt message. The voice prompt message prompts the user to perform a water outlet operation action within a predetermined time.
[0073] S40. The pressure sensor collects the pressure signal input by the user within a predetermined time and sends the pressure signal to the control module.
[0074] S50. When the control module determines that the change in the pressure signal collected by the pressure sensor matches the change in the pressure signal corresponding to the water outlet operation action, it controls the opening of the switching valve; if not, it controls the closing of the switching valve.
[0075] The infrared image sensor 5 is a sensor made of infrared rays with the function of collecting images. When there is an occlusion 8 below the water outlet 1, the infrared image sensor 5 can collect the image shape of the occlusion 8 and send it to the control module 3. The control module 3 is used to identify the type of the occlusion 8 and issue different control information according to the type of the occlusion 8. The recognition process specifically includes three situations:
[0076] The first situation: When the control module 3 determines that the type of the occlusion 8 is a preset type, it sends a first control signal to the switching valve 2. The preset type refers to the image of a human hand, specifically including various postures of human hands, which are stored in the control module 3. By comparing the image of the occlusion 8 with the image of the human hand, it is judged whether it is a human hand. If it is determined to be a human hand, the switching valve 2 is controlled to open, and water flows out from the water outlet 1.
[0077] The second situation: When the control module 3 determines that the type of the occlusion 8 is other types, and the other types refer to the situation where the image of the occlusion 8 obviously does not conform to the posture and structure of a human hand, it sends a second control signal to the switching valve 2 to control the switching valve 2 to remain in the closed state. For example, if the occlusion 8 is obviously a square object or the shape of an insect, etc., the control module 3 will send a second control signal to the switching valve 2 to make the switching valve 2 remain in the closed state.
[0078] The third case: When the control module 3 cannot determine the type of the occlusion 8, and the hand gesture image collected does not show this hand gesture image, but the occlusion 8 partially resembles the human hand structure. For example, for a person with a disability in the hand, then the control module 3 will send a third control signal to the voice module 4. After receiving the third control signal, the voice module 4 will correspondingly send out a voice prompt message, which is used to prompt the user to perform a water outlet action within a predetermined time. For example, if the voice module 4 stores the voice prompt content: "Please press the faucet." Then when the voice module 4 receives the third control signal from the control module 3, it will send out the above voice prompt. If there is indeed a user who needs to wash hands, then the user will press the faucet according to the voice prompt. If there is no user (it is a small animal or an insect) or the user has no need to wash hands, the action shown in the voice prompt will not be performed, further avoiding the situation where the existing water-saving faucet discharges water when there is an occlusion 8.
[0079] By setting up the infrared image sensor 5, the occlusion 8 below the water outlet 1 is collected and transmitted to the control module 3, which is handed over to the control module 3 for identification and different instructions are sent according to the judgment result to control the opening and closing of the switch valve 2. During this identification process, when it is determined that the type of the occlusion 8 does not conform to the preset type, the switch valve 2 is kept in the closed state. At the same time, a voice module 4 and a pressure sensor 6 are added to prompt the user to make corresponding actions to achieve the opening action of the switch valve 2, further avoiding the state where the faucet is accidentally opened when an insect or other animal or object is occluding, and reducing the waste of water resources.
[0080] Please refer to Figure 5 , in some embodiments, the faucet further includes a distance measuring sensor, and the distance measuring sensor is electrically connected to the control module; the method further includes:
[0081] S31. When the control module determines that the type of the occlusion is the preset type, the distance measuring sensor measures the distance from the water outlet to the occlusion below;
[0082] S32. The control module judges whether the distance transmitted by the distance measuring sensor is within the preset distance range. If so, it continues to control the opening of the switch valve; otherwise, it controls the closing of the switch valve.
[0083] When the type of the obstacle 8 is recognized as belonging to the preset type, it is further determined whether the distance between the obstacle 8 detected by the ranging sensor and the water outlet 1 is within the preset distance range. If it is within the preset distance range, the control module 3 controls the opening of the switching valve 2. If it is not within the preset distance range, the switching valve 2 is controlled to close. The preset distance range can be determined according to the height of the washbasin and the height of the faucet. This method can standardize the user's handwashing posture. When the user maintains a certain distance from the water outlet 1, the handwashing efficiency can be improved (being too close or too far from the water outlet 1 will result in incomplete handwashing). At the same time, it is avoided that the user places the hand at any distance below the water outlet 1, causing the switching valve 2 to always remain open and resulting in waste of water resources.
[0084] In some embodiments, the faucet further includes a timer, and the timer is electrically connected to the control module; the method further includes:
[0085] The timer counts the duration of the object blocking below the water outlet and the time interval between the start time point of the current block and the end time point of the previous block.
[0086] When the duration or time interval output by the timer is less than the preset time interval, the control module controls the switching valve to close.
[0087] After the control module 3 determines that the type of the obstacle 8 is the preset type, the control module 3 controls the opening of the switching valve 2. At the same time, the timer can count the duration of the object blocking below the water outlet 1 and the time interval between the start time point of the current block and the end time point of the previous block. If there is a duration or time interval less than the preset time interval, the switching valve 2 is controlled to close. By adding a timer, the duration of the obstacle 8 and the interval time between two handwashes can be counted and judged by the control module 3, effectively avoiding the phenomenon of water outflow under non-handwashing requirements and reducing the waste of water resources.
[0088] In some embodiments, the faucet further includes a random number generator and a prompt information storage module; the prompt information storage module stores the corresponding relationships between multiple water outlet operation actions and identification information; the method further includes:
[0089] The random number generator generates a random number; the value of the random number is one of the identification information set.
[0090] The control module retrieves the water outlet operation action corresponding to the generated random number according to the generated random number and controls the voice module to send out the corresponding prompt information.
[0091] When the control module 3 cannot determine the type of the obstacle 8, it will send the third control information to the voice module 4. At the same time, the third control information will also be sent to the random number generator. Through the random number generated by the random number generator, the prompt information corresponding to the random number is matched in the prompt information storage module and sent to the voice module 4, which is handed over to the voice module 4 to send the corresponding prompt information, so as to instruct the user to perform the corresponding water outlet operation action. In this embodiment, a pressure sensor 6 is provided at the execution position of the water outlet operation action. The pressure sensor 6 is used to collect the pressure change value curve generated during the user's execution of the water outlet action and send the pressure change value curve to the control module 3. If the pressure change value curve conforms to the pressure change value curve corresponding to the prompt information, the control switch valve 2 is opened. Otherwise, the control switch valve 2 remains in the closed state.
[0092] The above method can further prevent the user from making misoperations on the faucet. At the same time, the corresponding prompt information is different each time, which can increase the recognition of the opening methods of each faucet and prevent the user from opening multiple faucets synchronously, thus causing waste of water resources.
[0093] This embodiment also provides a readable computer storage medium, on which computer program instructions are stored. When the computer program instructions are executed by a processor, the method described above is implemented.
[0094] The storage medium / memory includes but is not limited to: RAM, ROM, magnetic disk, magnetic tape, optical disc, flash memory, USB flash drive, mobile hard disk, memory card, memory stick, network server storage, network cloud storage, etc. The processor includes but is not limited to CPU (Central Processing Unit), GPU (Graphics Processing Unit), MCU (Microprocessor), etc.
[0095] The above technical solution collects the obstacle 8 below the water outlet 1 through the infrared image sensor 5 and transmits it to the control module 3, which is handed over to the control module 3 for identification and sends different instructions according to the judgment result to control the opening and closing of the switch valve 2. During this identification process, when it is determined that the type of the obstacle 8 does not conform to the preset type, the switch valve 2 remains in the closed state. At the same time, a voice module 4 and a pressure sensor 6 are added to prompt the user to make corresponding actions to realize the opening action of the switch valve 2, further avoiding the state of the faucet being accidentally opened when blocked by insects or other animals or objects, and reducing the waste of water resources.
[0096] Finally, it should be noted that although the above embodiments have been described in the text and drawings of the specification of this application, the patent protection scope of this application cannot be limited thereby. Any technical solutions obtained by equivalent structure or equivalent process substitution or modification based on the essential concept of this application and using the content recorded in the text and drawings of the specification of this application, as well as directly or indirectly implementing the technical solutions of the above embodiments in other related technical fields, etc., are all included in the patent protection scope of this application.
