[0048] Figure 2 This is a side view of the urinal in a preferred embodiment of the present invention;

[0049] Figure 3This is a logic control diagram of the control mechanism in a preferred embodiment of the present invention. Detailed Implementation

[0050] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0051] See Figures 1-2 A urinal is provided, comprising a faucet mechanism 1, a urinal mechanism 2, a sensing mechanism 3, and a control mechanism, wherein the control mechanism is electrically connected to the faucet mechanism 1, the urinal mechanism 2, and the sensing mechanism 3. The urinal is installed in a toilet to provide a place for urination. The urinal mechanism 2 includes a urinal 21. The faucet structure includes a faucet body 11 and a washbasin 12. The washbasin 12 is connected above the urinal 21, and the water outlet of the faucet body 11 is located above the washbasin 12. After using the urinal 21, the user can use the water outlet of the faucet body 11 to wash their hands. The washbasin 12 can collect the wastewater after handwashing.

[0052] The faucet body 11 is connected to an external water source to dispense water through the outlet. The faucet body 11 can be a conventional faucet, for example, the faucet body 11 can only dispense cold water, or the faucet body 11 can be a thermostatic faucet, etc., and is not limited thereto.

[0053] The sensing mechanism 3 is arranged on the faucet body 11. The sensing mechanism 3 is a distance sensor or a signal sensor, such as a microwave sensor, an infrared sensor, or a Time-of-Flight (TOF) sensor. The sensing direction of the sensing mechanism 3 is facing forward to sense human body information. The sensing mechanism 3 can transmit this human body information to the control mechanism via wired or wireless means. The control mechanism receives the human body information detected by the sensing mechanism 3 and controls the faucet mechanism 1 and / or the urinal mechanism 2 to execute the corresponding water dispensing action according to a predetermined operating logic. In this embodiment, the control mechanism includes an electrical control box and an MCU (microcontroller unit) and a power supply module arranged in the electrical control box. The MCU has a built-in program to realize logic control. The MCU is electrically connected to the faucet mechanism 1, the urinal mechanism 2, and the sensing mechanism 3 to realize control.

[0054] The urinal mechanism 2 further includes a water storage module 22, which includes a water tank 221 and a first valve mechanism. The water tank 221 includes an inlet 2211 and an outlet 2212. The washbasin 12 is fluidly connected to the water tank 221, meaning the inlet 2211 is connected to the bottom drain of the washbasin 12. Wastewater from handwashing can enter the inlet 2211 through the bottom drain and remain in the water tank 221. The outlet 2212 is connected to the urinal 21. The first valve mechanism is arranged on the outlet 2212 to control the opening and closing of the outlet 2212. The control mechanism is electrically connected to the first valve mechanism to control the opening and closing of the first valve mechanism to achieve the opening and closing of the outlet 2212. In this embodiment, the first valve mechanism is a solenoid valve. The urinal mechanism 2 further includes a water outlet module 23; the water outlet module 23 is used to flush the urinal mechanism 2; the water outlet module 23 also includes a second valve mechanism for controlling its water outlet, the control mechanism being electrically connected to the second valve mechanism to control the opening and closing of the second valve mechanism. The water outlet module 23 is directly connected to an external water source to achieve water outlet. In this embodiment, the second valve mechanism is a solenoid valve. The faucet mechanism 1 further includes a third valve mechanism for controlling the water outlet of the faucet body 11, the control mechanism being electrically connected to the third valve mechanism to control the opening and closing of the third valve mechanism. In this embodiment, the third valve mechanism is a solenoid valve.

[0055] The control mechanism acquires and judges the first human body information sensed by the sensing mechanism 3; when the first human body information indicates that the human body is in the first area used to represent the user urinating for a first predetermined time, it acquires and judges the second human body information sensed by the sensing mechanism 3; when the second human body information indicates that the human body is in the second area used to represent the user wanting to wash their hands, it controls the faucet mechanism 1 to dispense water; when the second human body information indicates that the human body is in the third area, it controls the urinal mechanism 2 to dispense water for rinsing, the third area being used to represent the user leaving the first and second areas.

[0056] The first, second, and third areas are located at different distances from the urinal. More specifically, the second area is located less than the first area, and the third area is located more than the first area.

[0057] The specific explanation is as follows: When the first human body information indicates that the human body is in the first area and this continues for a first predetermined time, it can be determined that the user has the intention to urinate. At this time, the control mechanism can also control the water outlet module 23 of the urinal mechanism 2 to discharge water to achieve pre-flushing. The sensing mechanism 3 continuously senses the human body information between itself and the human body. The control mechanism is configured to: when the second human body information indicates that the human body is in the second area, control the faucet mechanism 1 to discharge water so that it can be contained in the water storage module 22; when the second human body information indicates that the human body is in the third area and this continues for a second predetermined time, control the water storage module 22 of the urinal mechanism 2 to discharge water to flush the urinal mechanism 2.

[0058] More specifically, the urinal mechanism includes the urinal 21, a flushing mechanism, and a water storage module 22. The water storage module 22 is connected to the faucet mechanism 1 and is used to contain water discharged from the faucet mechanism 1. The flushing mechanism is used to flush the urinal. After the step of obtaining and judging the second human information, the mechanism further includes: when the second human information indicates that the human body enters the second area and then enters the third area: controlling the flushing mechanism to discharge water at a first water flow rate; and when the second human information indicates that the human body enters the second area and then enters the third area: controlling the water storage module 22 to discharge water and then controlling the flushing mechanism to flush at a second water flow rate; wherein the first water flow rate is greater than the second water flow rate.

[0059] When the second human body information indicates that the user is in the second area, it can be determined that the user intends to wash their hands and has already placed their hands under the water outlet of the faucet body 11. The control mechanism controls the third valve mechanism to open to allow water to flow out. This continues until the second human body information indicates that the user is in the first or third area. After washing hands, the wastewater enters the water storage module 22. When the second human body information indicates that the user is in the third area for a second predetermined time, it is determined that the user has finished urinating and left. The control mechanism controls the first valve mechanism of the water storage module 22 to open to flush the urinal 21. The amount of water used for this flushing is less than the amount of water that the urinal mechanism normally produces and utilizes the wastewater from handwashing, thus achieving water conservation.

[0060] When the second human body information indicates that the human body is in the third area for a third predetermined time, the water outlet module 23 of the urinal mechanism 2 is controlled to discharge water to rinse the urinal mechanism 2; at this time, it is determined that the user leaves without washing his hands, and the control mechanism controls the second valve mechanism to open to rinse the urinal 21.

[0061] In this embodiment, the second predetermined time and the third predetermined time are the same; of course, they can also be set to different times.

[0062] In this embodiment, the sensing mechanism 3 is a ranging sensor (e.g., a laser ranging sensor). The ranging sensor can be one or more. When there is only one ranging sensor, it can determine the distance to the human body to obtain distance information S. In some simpler alternatives, the sensing mechanism can also be a first infrared sensor for sensing human body information in a first area and a second infrared sensor for sensing human body information in a second area. The first and second infrared sensors determine the first and second human body information respectively by sensing the presence or absence of a human body. For details, see [link to documentation]. Figure 3 The sensing mechanism 3 detects the distance information S between itself and the human body after power-on. The control mechanism receives this information S (the distance between the human body and the urinal) and makes a judgment. When the human body information S is greater than D1 and less than D2 (the area between D1 and D2 is the first region), it is determined that the human body has entered the sensing area. In this embodiment, D1 is 10 cm and D2 is 50 cm. D1 and D2 can be adjusted according to different usage scenarios. After determining that the human body has entered the first region, time point T1 is recorded, and time point T2 is recorded for the continuous detection of the human body (the area between T1 and T2 is the first predetermined time). In this embodiment, the first predetermined time is 2 seconds. If the human body stays in the first region for more than or equal to 2 seconds, it is determined that the person intends to urinate and is using the urinal 21. At this time, the control mechanism controls the water outlet module 23 to dispense water for pre-flushing. When the detected human body information S is less than D1 (set to 10 cm), the person is in the second region, and it is determined that the person has finished urinating and has put their hand under the faucet, indicating an intention to wash their hands. At this point, the faucet body 11 is turned on to dispense water until S is greater than or equal to D1 (greater than D1 indicates that the hands have been washed and the person has left the faucet). The time T3 for the last time a person is detected in the sensing area is recorded. If no person is detected in the first area for a period of time T4, and T4 minus T3 (i.e., the second predetermined time) is greater than or equal to 3 seconds, it is determined that urination has been completed and the person has left. After the person finishes urinating and leaves, the urinal is flushed. If the person left after washing their hands, the solenoid valve corresponding to the reserved water in the water storage tank 221 is opened to flush the urinal. If the person left without washing their hands, the solenoid valve of the water outlet module 23 is opened to flush the urinal.

[0063] This invention also includes a water outlet control method, which is applied to control the water outlet of the urinal. The water outlet control method includes: acquiring first human body information; and judging the first human body information. When the first human body information indicates a human body in a first area, acquiring second human body information and judging it: when the second human body information indicates a human body in a second area, controlling the faucet mechanism 1 to outlet water; or when the second human body information indicates a human body in a third area, controlling the urinal mechanism 2 to outlet water for flushing; wherein the first area, the second area, and the third area are at different distances from the urinal. The first human body information and the second human body information are acquired by the sensing mechanism 3, and the control mechanism acquires the first human body information and the second human body information and controls the faucet mechanism 1 and the urinal mechanism 2 to outlet water using the above method.

[0064] In the water discharge control method, the first human body information is judged. When the first human body information is a human body in the first area for a first predetermined time, the second human body information is obtained and judged. In this water discharge control method, the judgment of the first predetermined time is added, so that it can be determined that the user has the intention to urinate before the second human body information is obtained.

[0065] In the water outlet control method, the distance from the second area to the urinal is less than the distance from the first area to the urinal; the distance from the third area to the urinal is greater than the distance from the first area to the urinal. Dividing the first, second, and third areas by distance is suitable for conventional ranging sensors and has wide applicability.

[0066] In the water discharge control method, the step of controlling the urinal mechanism 2 to discharge water for rinsing when the second human information indicates that the human body is in the third region specifically means: when the second human information indicates that the human body is in the second region, controlling the faucet mechanism 1 to discharge water, and controlling the urinal mechanism 2 to discharge water when the second human information indicates that the human body is in the third region for a second predetermined time.

[0067] In this embodiment, the water dispensing control method can be an executable program stored in a memory. The present invention also provides an electronic device including a memory and a processor, the processor executing the executable program and directly applied to a urinal having a faucet mechanism 1 and a urinal mechanism 2.

[0068] In this embodiment, the present invention also provides a water outlet control device applied to a urinal. The urinal includes a faucet mechanism 1 and a urinal mechanism 2. The water outlet control device includes: a human body information acquisition module configured to acquire first human body information; a distance judgment module configured to judge the first human body information; the human body information acquisition module is further configured to acquire second human body information when the first human body information indicates that the human body is in a first area used to represent the user urinating; the distance judgment module is further configured to make a judgment based on the second human body information; a water outlet control module configured to control the faucet mechanism 1 to dispense water when the second human body information indicates that the human body is in a second area used to represent the user wanting to wash their hands; the water outlet control module is further configured to control the urinal mechanism 2 to dispense water for rinsing when the second human body information indicates that the human body is in a third area; the third area is used to represent that the user has left the first area and the second area.

[0069] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
