Technical Field

[0001] This invention relates to the field of bathroom facilities technology, and in particular to a flushing control method, an automatic sensor flusher, and a urinal. Background Technology

[0002] In existing technology, urinals typically require a final flush after the user finishes urinating to remove the urine from the urinal. However, they are not flushed during urination. This results in a pungent odor and a poor user experience. Furthermore, the urine directly contacts the inner wall of the urinal during use, which can cause waste to adhere to the inner wall. Even with a final flush, waste residue may remain on the inner wall, affecting the hygiene level of public restrooms.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, and not all of the structures.

Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0023] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone.

[0024] In the embodiments of the present invention, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0025] In existing technology, urinals typically require a final flush after the user finishes urinating to remove the urine from the urinal. However, they are not flushed during urination. This results in a pungent odor and a poor user experience. Furthermore, the urine directly contacts the inner wall of the urinal during use, which can cause waste to adhere to the inner wall. Even with a final flush, waste residue may remain on the inner wall, affecting the hygiene level of public restrooms.

[0026] To address the aforementioned technical problems, this application provides a flushing control method applied to an automatic sensor flusher. The automatic sensor flusher uses this flushing control method to flush, which can reduce the pungent odor during urination and reduce the residue of waste on the inner wall of the urinal, thereby improving the hygiene level of the toilet and the user's toilet experience.

[0027] like Figure 1As shown, the automatic sensor flushing device includes a sensor module 100, a water circuit module 300, and a valve assembly 400 disposed in the water circuit module 300. The sensor module 100 is used to sense and monitor the presence of a target object (usually a user using the toilet). The water circuit module 300 can dispense water under the control of the valve assembly 400, specifically dispensing water into the urinal. Figure 2 As shown, the flushing control method provided in this application includes the following steps: S1. Control sensor module 100 confirms whether a target object exists in the monitoring area; S2. If so, before confirming that the target object has left the monitoring area, control the valve assembly 400 to discharge water in the first preset mode; The first preset mode includes a continuous flushing phase and / or an intermittent flushing phase.

[0028] It should be noted that continuous flushing means that the water circuit module 300 continuously and uninterruptedly dispenses water into the urinal within a certain period of time; intermittent flushing means that the water circuit module 300 dispenses water multiple times within a certain period of time, with time intervals between each dispensing.

[0029] Furthermore, the automatic sensor flusher also includes a control module 200. The sensor module 100 is connected to the valve assembly 400 through the control module 200. The control module 200 can receive signals from the sensor module 100 and control the valve assembly 400 to open or close according to the signals from the sensor module 100. The valve assembly 400 is used to dispense water or stop dispensing water under the control of the control module 200.

[0030] The flushing control method provided in this application, after the sensing module 100 confirms that the target object (user) has entered the monitoring area, and before confirming that the user has left the monitoring area, controls the valve assembly 400 to flush water in a continuous and / or intermittent manner. During the user's entire toilet use process, it can reduce the direct contact between urine and the inner wall of the urinal, so that the residual urine in the urinal can be diluted and flushed away in time, reducing the retention time of urine on the inner wall surface of the urinal and in the water seal, reducing the possibility of bacterial decomposition and odor production, and significantly reducing the concentration of odorous gases such as ammonia in the toilet air. This solves the problem of pungent odors irritating the user's respiratory tract, helps to improve the freshness and comfort of the toilet environment, and improves the hygiene level of public toilets and user satisfaction.

[0031] Specifically, in step S1, the monitoring area can be a certain range in front of the urinal, and the sensing module 100 can sense the monitoring area using infrared sensing, laser sensing, or other methods. The control module 100 senses the monitoring area, and when it confirms the presence of a target object within the monitoring area, it sends a signal to the control module 200. After receiving the signal from the sensing module 100, the control module 200 sends a corresponding command to activate the valve assembly 400, thereby causing the water circuit module 300 to discharge water in a first preset mode.

[0032] For example, the sensing module 100 may include an infrared sensor, a laser sensor, a microwave sensor, etc., but is not limited to the types of sensors listed, and this application does not impose strict limitations on this.

[0033] In step S2, the system continuously detects and confirms whether the target object (user) has left the monitoring area. If the user has not left the monitoring area, the control valve assembly 400 continues to discharge water in the first preset mode.

[0034] like Figure 3 As shown, the flushing control method also includes the following steps: S3. After confirming that the target object has left the monitoring area, control the valve assembly 400 to discharge water in the second preset mode, or control the valve assembly 400 to stop discharging water.

[0035] In some embodiments, after confirming that the user has left the monitoring area, the control valve assembly 400 dispenses water in a second preset mode, automatically performing a final flushing operation. This second preset mode can be set to a larger water volume or a stronger water flow as needed, effectively removing urine, foam, and other contaminants remaining on the ceramic surface during use, while maintaining the water seal level stably above the standard threshold. This final flushing using the second preset mode eliminates the possibility of urine residue being decomposed by bacteria, producing ammonia and other odors, ensuring the cleanliness of the water seal inside the urinal, and leaving virtually no urine residue.

[0036] In other embodiments, after confirming that the user has left the monitoring area, the control valve assembly 400 stops water flow and no further flushing is performed. For example, in scenarios where the dirt has been sufficiently flushed away and cleaning has been completed after water flow through the first preset mode, and the water seal level is up to standard, water flow can be stopped after confirming that the user has left the monitoring area, thereby avoiding unnecessary secondary flushing and achieving extreme water conservation.

[0037] like Figure 4 As shown, in step S1 of this application, the step of "controlling the sensing module 100 to confirm whether a target object exists in the monitoring area" includes: S11. When the sensing module 100 senses the presence of a target object in the monitoring area, a first duration t1 is obtained; wherein, the first duration t1 is the duration of the target object in the monitoring area. S12. When the first duration t1 reaches the first set threshold T01, it is confirmed that there is a target object in the monitoring area.

[0038] In public restrooms, situations frequently arise where people quickly pass by urinals, accidentally enter the sensing area, or briefly stay and then leave. If the sensing module 100 triggers flushing immediately upon detecting a target object, it results in a large amount of ineffective flushing, causing significant water waste. In this embodiment, the presence of a target object (user) is only confirmed in the monitoring area after the target object is sensed and its duration reaches a first preset threshold. That is, the presence is confirmed and flushing is triggered only when the user remains in the monitoring area for a duration that reaches the first preset threshold. This effectively filters out invalid signals such as brief passages and accidental entry, ensuring that flushing is only initiated when the user has a clear intention to use the restroom, significantly reducing the number of ineffective flushes and conserving water.

[0039] For example, the value range of the first set threshold T01 can be 1.5s to 4s. For example, the value of the first set threshold T01 can be 1.5s, 2s, 2.5s, 3s, 3.5s, 4s, etc., but it is not limited to the listed values ​​and ranges.

[0040] Continue reading Figure 4 In step S2, the step of "confirming that the target object has left the monitoring area" includes: S21. When the sensing module 100 senses that there is no target object in the monitoring area, a second duration t2 is obtained; wherein, the second duration t2 is the duration when there is no target object in the monitoring area. S22. When the second duration t2 reaches the second set threshold T02, confirm that the target object has left the monitoring area.

[0041] During normal toilet use, the sensing signal may briefly disappear due to minor body movements, limb actions, fluctuations in the sensitivity of the sensor module 100, or environmental interference. If the system immediately determines that "the target object has left," it will interrupt the first preset mode of water dispensing, leading to premature triggering of the second preset mode of water dispensing after the user leaves, or even stopping water dispensing altogether. This can result in incomplete cleaning and a drop in the water seal. In this embodiment, the system only confirms that the user has left the monitoring area after sensing that no target object is present in the monitoring area and that the absence of the target object has lasted for a period of time reaching a second preset threshold. This ensures that the flushing logic is not interrupted by minor interference during execution, guaranteeing the complete execution of the first preset mode of flushing and the continuous stability of the water seal.

[0042] More importantly, due to the existence of the second preset threshold, the interval between the moment the sensing module 100 detects the user leaving and the execution of the second preset mode is the second preset threshold. In other words, the timing starts the moment the user leaves the monitoring area. When the timing reaches the second preset threshold, it is confirmed that the target has left the monitoring area. At this time, the second preset mode is used for flushing. Since the user is far away from the monitoring area at this time, the water flow or noise of the second preset mode can be avoided from interfering with the user, thus improving the toilet experience.

[0043] For example, the value range of the second set threshold T02 can be 1.5s to 4s. For example, the value of the second set threshold T02 can be 1.5s, 2s, 2.5s, 3s, 3.5s, 4s, etc., but it is not limited to the listed values ​​and ranges.

[0044] In this embodiment, the first preset water discharge mode includes a continuous flushing phase and / or an intermittent flushing phase. After confirming that the target object has left the monitoring area, the control valve assembly 400 discharges water in a second preset mode, or the control valve assembly 400 stops discharging water. The specific solution of this application is illustrated below with reference to three embodiments.

[0045] Example 1 like Figure 5 As shown, in the flushing control method provided in this embodiment, the step of "controlling the valve assembly 400 to discharge water in a first preset mode" includes: Continuous flushing phase: Control valve assembly 400 continuously flushes the first water volume; Intermittent flushing phase: Control valve assembly 400 flushes a second volume of water at preset intervals.

[0046] The steps of “controlling the valve assembly 400 to discharge water in the second preset mode” include: Control valve assembly 400 continuously flushes the third water volume; Among them, the third water volume is greater than the first water volume and also greater than the second water volume.

[0047] In this embodiment, the flushing process is divided into three stages. The first stage is a continuous flushing stage, the second stage is an intermittent flushing stage, and after confirming that the user has left the monitoring area, the third stage is performed to flush the urinal for the last time, with the flushing volume being the third volume.

[0048] Specifically, when a user is confirmed to be present in the monitoring area (the presence of the user is sensed and the duration of presence reaches the first set threshold), the continuous flushing phase is first executed. The water circuit module 300 continuously flushes the first volume of water, which can pre-wet the ceramic inner wall of the urinal before the user actually urinates, forming a water film. When the urine falls subsequently, it is not easy to stick to the ceramic surface, so it is easier to be quickly carried away by the subsequent water flow, significantly improving the cleaning effect and reducing urine residue.

[0049] After the continuous flushing phase ends, an intermittent flushing phase begins, flushing a second volume of water at preset intervals. This intermittent flushing logic continuously flushes away waste during the user's urination, reducing the time urine remains on the inner wall of the urinal and in the water seal, thus minimizing pungent odors during use. The combination of continuous and intermittent flushing phases ensures the cleanliness of the urinal's ceramic surface while achieving good water conservation.

[0050] For example, the preset duration can range from 5s to 8s, such as 5s, 6s, 7s, 8s, etc., but is not limited to the listed values ​​and ranges. In this embodiment, the preset duration is preferably 8s. During the intermittent flushing phase described above, water is flushed once every 8s until the user leaves.

[0051] It should be noted that during urination, the urinal flushes approximately every 8 seconds, effectively masking the odor of urine. It has been verified that ammonia volatilizes to approximately 8 ppm within 12 seconds; flushing every 8 seconds keeps the ammonia level below 5 ppm. Furthermore, the average urination time for a normal male is 15-30 seconds; approximately 8 seconds ensures both odor and waste removal while conserving water.

[0052] Furthermore, the continuous flushing phase only requires a small initial water volume to pre-wet the water, and the subsequent intermittent flushing phase replenishes water with a small second water volume at intervals, avoiding water waste caused by large-volume flushing. In addition, since the user is still urinating when the continuous flushing phase and the intermittent flushing phase are performed, the small water volume can avoid generating a lot of noise that would affect the user's experience.

[0053] After confirming that the user has left the monitoring area, the final flushing stage is executed. A third, stronger flush, with a volume greater than the first and second, is applied continuously to create a powerful water flow that thoroughly washes the entire inner wall of the urinal and the drain pipe inlet, completely removing any residual waste. This ensures the ceramic surface is restored to a clean state after use, preventing stubborn yellow stains or odors from forming after the waste dries. It also ensures the water seal level remains consistently above the standard threshold. Because there is a time interval between the start of the final flushing stage and the moment the user leaves the monitoring area (i.e., the second set threshold), the powerful flushing with a larger volume of water will not disturb the user.

[0054] For example, the first water volume is 0.3L, the second water volume is 0.3L, and the third water volume is 1L. Of course, the values ​​of the first, second, and third water volumes are not limited to the listed values, and this embodiment does not impose strict restrictions on them.

[0055] For example, in this embodiment, the valve assembly 400 may include a solenoid valve, through which the opening and closing of the valve assembly 400 and the flow rate are controlled.

[0056] Example 2 like Figure 6 As shown, in the flushing control method provided in this embodiment, the step of "controlling the valve assembly 400 to discharge water in a first preset mode" includes: Continuous flushing phase: Control valve assembly 400 continuously flushes.

[0057] Furthermore, the flushing control method also includes: After confirming that the target object has left the monitoring area, the control valve assembly 400 stops the water flow.

[0058] That is, in this embodiment, the first preset mode includes a continuous flushing stage. After confirming that there is a user in the monitoring area, the valve assembly 400 is immediately controlled to discharge water until the user leaves the monitoring area, at which point the valve assembly 400 is controlled to stop discharging water.

[0059] From the moment a user is detected in the monitoring area (the presence of a user is sensed and remains above a first preset threshold) until the user leaves the monitoring area (the absence of a user is sensed and remains below a second preset threshold), the water module 300 maintains a continuous flushing state. This continuous water flow effectively washes away waste during urination, reducing the time urine remains on the inner wall of the urinal and in the water seal. This effectively eliminates odor release during urination, reduces pungent smells, and improves the hygiene level of the public restroom and user satisfaction. Because of the continuous flushing, the ceramic surface of the urinal remains largely clean. Therefore, after confirming the user's departure, the control valve assembly 400 stops the water flow, eliminating the need for additional post-flushing, thus helping to conserve water resources.

[0060] In addition, the continuous flushing during urinal use enhances the user's psychological experience. Furthermore, the longer flushing time results in a gentler, more subtle water flow and reduced noise, all while maintaining the same water volume.

[0061] For example, in this embodiment, the valve assembly 400 may include a solenoid valve, through which the opening and closing of the valve assembly 400 and the flow rate are controlled.

[0062] Example 3 like Figure 7 As shown, in the flushing control method provided in this embodiment, the step of "controlling the valve assembly 400 to discharge water in a first preset mode" includes: Continuous flushing phase: Control valve assembly 400 continuously flushes at the first flow rate.

[0063] Furthermore, the step of "controlling the valve assembly 400 to discharge water in the second preset mode" includes: Strong flushing phase: Control valve assembly 400 continuously flushes with the fourth water volume at the second flow rate; The second flow rate is greater than the first flow rate.

[0064] In this embodiment, the first preset mode uses a small first flow rate for continuous flushing. The water flow is delicate and the flow rate is slow. The water noise generated when it impacts the ceramic inner wall of the urinal and the water seal liquid surface is significantly reduced. While ensuring that the waste is flushed away in time and maintaining the water seal level, it will not cause ear-piercing noise interference, creating a quiet toilet environment for users. It is suitable for places that are sensitive to noise.

[0065] The second preset mode uses a larger second flow rate to continuously flush with a fourth water volume. After confirming that the user has left the monitoring area, a strong flush is performed. The large flow rate has a higher flushing force, which can effectively wash away the dirt remaining on the ceramic surface and thoroughly clean the inside of the urinal. This prevents residual urine in the water seal of the urinal, thus preventing the possibility of odor caused by dirt in the water seal.

[0066] For example, the fourth water volume can be, but is not limited to, 0.8L or 1L, etc., and there is no strict limitation here. The magnitude of the first and second flow rates can be set according to parameters such as the total flush volume, and there is no limit to their specific values ​​here.

[0067] like Figure 8 and Figure 9 As shown, the valve assembly 400 in this embodiment includes a first valve 450 and a second valve 460, both of which are selectively connected to the water inlet of the water circuit module 300; the flushing control method includes: When water is discharged in the first preset mode, the first valve 450 is opened and the second valve 460 is closed. When water is discharged in the second preset mode, the second valve 460 is opened and the first valve 450 is closed.

[0068] In this embodiment, the first stage of low-flow flushing and the second stage of high-flow flushing are achieved by controlling the opening of one of the first valve 450 and the second valve 460. When setting it up, the first valve 450 can be configured with a low-flow channel and the second valve 460 can be configured with a high-flow channel. Compared with adjusting the first and second flow rates by relying on the opening of a single valve, the control is simpler and more reliable. The low-flow channel of the first valve 450 achieves continuous silent flushing, and the high-flow channel of the second valve 460 achieves powerful flushing.

[0069] like Figure 8 and Figure 9As shown, the valve assembly 400 provided in this embodiment also includes a valve body 410. A first valve 450 and a second valve 460 are both disposed on the valve body 410. Both can be, for example, solenoid valves. The valve body 410 is provided with a valve inlet 420, a first outlet 430, a second outlet 440, an inlet channel 470, a first water path 480, and a second water path 490. Water input through the inlet of the water path module 300 enters the intermediate inlet channel 470 through the valve inlet 420. The water in the intermediate inlet channel 470 can flow to the first valve 450 and the second valve 460 respectively through the branch outlet. When the first valve 450 is open, water flows through the first valve 450 into the first water path 480 and exits through the first outlet 430, achieving continuous silent flushing at a first flow rate. When the second valve 460 is open, water flows through the second valve 460 into the second water path 490 and exits through the second outlet 440, achieving powerful flushing at a second flow rate.

[0070] This application also provides an automatic sensor flusher for implementing the flushing control method described above. (Refer to...) Figure 1 The automatic sensor flushing device includes a sensing module 100, a control module 200, a water circuit module 300, and a valve assembly 400 disposed in the water circuit module 300. The sensing module 100 is used to sense whether a target object exists in the monitoring area. The control module 200 can control the valve assembly 400 to dispense water in a first preset mode, at least after confirming the presence of a target object in the monitoring area and before confirming that the target object has left the monitoring area. Of course, the control module 200 can also control other modes.

[0071] Furthermore, the automatic sensor flusher also includes a valve assembly 400. The sensing module 100 is connected to the valve assembly 400 through the control module 200. The control module 200 can receive signals from the sensing module 100 and control the valve assembly 400 to open or close according to the signals from the sensing module 100. The valve assembly 400 is used to dispense water or stop dispensing water under the control of the control module 200, thereby causing the water circuit module 300 to dispense water or stop dispensing water, as described above.

[0072] This application embodiment also provides a urinal, including a urinal and an automatic sensor flusher as described above. The water outlet of the water circuit module 300 of the automatic sensor flusher is connected to the urinal so that water enters the urinal, which can reduce the pungent odor during the user's urination process and reduce the residue of dirt on the inner wall of the urinal, thereby improving the hygiene level of the toilet and the user's toilet experience.

[0073] Specifically, the sensing module 100 can be installed on the front side of the urinal to sense whether a user is present in the area in front of the urinal.

[0074] The urinal provided in this application embodiment, by employing the flushing control method described above, after the sensing module 100 confirms that the target object (user) has entered the monitoring area, and before confirming that the user has left the monitoring area, controls the valve assembly 400 to flush water in a continuous and / or intermittent manner. During the user's entire toilet use process, it can reduce the direct contact between urine and the inner wall of the urinal, so that the residual urine in the urinal can be diluted and flushed away in time, reducing the retention time of urine on the inner wall surface of the urinal and in the water seal, reducing the possibility of bacterial decomposition and odor production, and significantly reducing the concentration of odorous gases such as ammonia in the bathroom air. This solves the problem of pungent odors irritating the user's respiratory tract, helps to improve the freshness and comfort of the toilet environment, and improves the hygiene level of public toilets and user satisfaction.
