[0029] The specific implementation of the embodiment of the utility model is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the embodiment of the utility model, and is not used to limit the embodiment of the utility model.

[0030] The utility model first provides a urinal flushing control system 100, such as Figure 1As shown, the control system may include a sensing probe 110 and a controller 120 , wherein the controller 120 is electrically connected to the sensing probe 110 to receive a sensing signal sent by the sensing probe 110 .

[0031] Among them, Figure 2 As shown, the sensing probe 110 is used to generate a sensing signal when sensing an obstacle (sensing object) within a set distance, and stop generating a sensing signal when no obstacle is sensed within the set distance. The set distance can be 55-75cm. For example, the set distance is 65cm, that is, once a sensing object enters within a distance of 65cm in front of the sensing probe 110, a sensing signal is generated.

[0032] In one embodiment, the sensing probe 110 may be any sensor capable of measuring distance, such as an infrared signal sensor and / or a microwave signal sensor. In the case where the sensing probe includes an infrared signal sensor, the sensing probe 110 may also include an infrared signal transmitter, two lenses, and an infrared signal receiver. Figure 3 As shown, the sensing principle is: through this lens imaging, two closely adjacent infrared receiving tubes receive light signals and perform signal processing, it is possible to determine whether the target is within the detection range based on the principle of geometric optics, for example, it can be determined based on the receiving time of the receiver, or based on the vertical distance of the receiving position of the receiver. In addition, the sensing probe 110 can also be further combined with basic specific algorithm support and single-chip intelligent computing processing modules to achieve more functions, so as to adapt to more scenarios.

[0033] In one embodiment, the present application further uses the anti-color difference sensing human body sensing detection technology, which is integrated into the sensing probe 110, so as to obtain an integrated anti-color difference infrared sensor that can be used in sensing sanitary ware products. This sensor is different from the conventional infrared emission and reflection detection scheme used in the prior art. This is because the applicant found that the infrared emission and reflection detection scheme of the prior art only detects the amount of reflection when implementing the utility model. For the application scenario when the user wears dark (black) clothes, the sensitivity of the induction is greatly reduced, resulting in the defects of short sensing distance, insensitivity, and misjudgment of sensing. In this regard, the present application uses anti-color difference technology and adopts the principle of geometric positioning. Only one sensing probe can be used at one position to complete all detection and judgment, which can effectively deal with the induction of black clothes, so that the sensing distance is independent of the color of the target object, thereby solving this problem. In addition, since only one sensing probe is used, the possibility of damage is greatly reduced compared with the scheme of multiple sensing probes, and the reliability is higher. In addition, the present application also achieves higher measurement accuracy through a special optical lens. And the circuit design is optimized, with the characteristics of low power consumption.

[0034] The controller 120 may include a first signal generating module 121 and a second signal generating module 122. The first signal generating module 121 is used to generate a first control signal when the sensing signal is disconnected to control the first flushing device to spray clean water. In one embodiment, the first control signal is also used to execute: control the first flushing device to spray clean water for 1-10 seconds after 2-5 seconds. The flushing time can be adjusted in multiple levels according to actual needs. For example, the adjustment range can be divided into 5 levels: 1 second, 3 seconds, 5 seconds, 7 seconds, and 9 seconds.

[0035] Among them, the duration of the sensing signal should be greater than the set time, so that when the user only stays / passes by temporarily, even if the sensing probe 110 generates a sensing signal, due to the short duration of the sensing signal, the first control signal will not be generated to avoid water spraying, thereby achieving the beneficial effect of water saving. In one embodiment, the set time can be 3-8 seconds, for example, set to 3 seconds. That is to say, when the user enters the probe sensing area, after 3 seconds of sensing, the first signal generating module 121 senses and determines that it is valid. Then, when the user leaves, the sensing signal is disconnected, and the first signal generating module 121 sends a first control signal to control the first flushing device to spray clean water for 5 seconds after the user leaves for 3 seconds, thereby completing the cleaning and flushing.

[0036] The second signal generating module 122 is used to generate a second control signal when the number of times the first control signal is generated reaches a multiple of the set number of times, so as to control the second flushing device to spray disinfectant water. In one embodiment, the set number of times can be 5-8 times, for example, set to 5 times. That is to say, every 5 times the first control signal is generated, it means that after every 5 times the urinal is used, after the flushing is completed, the second flushing device is controlled to spray disinfectant water for disinfection flushing to keep the urinal hygienic and prevent bacteria from breeding. In one embodiment, the second control signal is also used to execute: control the second flushing device to spray disinfectant water for 5-15 seconds after 2-5 seconds. Among them, the time for flushing disinfectant water can be adjusted in multiple levels according to actual needs. For example, the adjustment range can be divided into 5 levels: 5 seconds, 9 seconds, 11 seconds, 13 seconds, and 15 seconds.

[0037] In one embodiment, the disinfectant water may include disinfectant water pre-placed in the urinal, or may include disinfectant water generated in real time as needed. For example, the disinfectant water (for example, including hypochlorous acid) may be generated by electrolyzing water. In this case, the electrolysis generating device of the disinfectant water may be, for example, Figure 4As shown. Its generation principle is: during the working process, water molecules (H2O) decompose into hydrogen ions (H+) and oxygen ions (O-). Oxygen ions as anions react with other water molecules around them and generate hydroxyl groups (OH-). At this time, a small amount of hypochlorous acid (HOCL) containing trace chlorine components in tap water also decomposes into HCL+, O-, and produces disinfecting and bactericidal substances such as dissolved oxygen (O-, O3-), anions, etc. Therefore, the electrolyzed water module can be used to achieve the effects of strong disinfection, sterilization, and purification of organic and non-organic substances through the hypochlorite, hydroxyl (OH-) and dissolved oxygen (O-, O3-) anions generated in the above manner, thereby keeping the urinal hygienic and free of bacteria.

[0038] That is to say, the above scheme of electrolysis to generate disinfectant water can utilize the internal software and hardware of the controller 120, for example, a highly integrated microprocessor can be used to count the number of users to achieve accurate detection, timing, and counting. In one embodiment, after every 5 uses of the urinal, after the flushing is completed, the electrolysis water module can be started 3 seconds later to perform disinfection flushing for 10 seconds to keep the urinal clean and prevent bacteria from growing.

[0039] In one embodiment, the controller 110 may further include a monitoring module 123, which is used to enable the first signal generating module 121 to generate a first control signal and / or enable the second signal generating module 122 to generate a second control signal when it is detected that the first signal generating module 121 has not generated a first control signal for 12-24 hours. That is to say, for example, when no one uses the urinal for 24 hours, a 3-second cleaning flush and / or a 3-second disinfection flush is automatically performed, so that the urinal can be kept clean and free of bacteria even when no one uses it for a long time.

[0040] In a preferred embodiment, the control logic parameters of the controller 110 are shown in Table 1:

[0041] Table 1: Control logic parameters of the controller

[0042]

[0043] Through the above technical solution, the deep cleaning of the urinal can be automatically completed in a simple and efficient manner. That is, by regularly spraying disinfectant water into the urinal, the urinal is kept clean and bacteria-free. Even in the process of long-term use, there will be no phenomenon of incomplete flushing and residual dirt, which optimizes the user's subsequent experience and can also be applied on a large scale.

[0044] On the other hand, the utility model also provides a urinal 200, such as Figure 5As shown, the urinal may include: the urinal flushing control system 100 as described above, a first flushing device 210 and a second flushing device 220 .

[0045] The first flushing device 210 is used to spray cleaning water in response to the first control signal sent by the control system 100. In one embodiment, the first flushing device 210 is also used to spray cleaning water for 1-10 seconds after 2-5 seconds in response to the first control signal. For example, the first flushing device 210 can spray cleaning water for 5 seconds after the user (stays for more than 3 seconds) leaves for 3 seconds, thereby completing the cleaning flushing.

[0046] The second flushing device 220 is used to spray disinfectant water in response to the second control signal sent by the control system 100. In one embodiment, the second flushing device 220 is also used to spray disinfectant water for 5-15 seconds after 2-5 seconds in response to the second control signal. For example, after the second flushing device 220 uses the urinal for every 5 times, after the flushing is completed, the electrolytic water module is started 3 seconds later to perform disinfection flushing for 10 seconds to keep the urinal clean and prevent bacteria from growing.

[0047] In one embodiment, if Figure 6 As shown, the water supply circuit of the first flushing device 210 and the water supply circuit of the second flushing device 220 are independent of each other. That is to say, the clean water and the disinfecting water use independent water circuits and enter the flushing nozzles respectively. Each circuit is equipped with a one-way valve to isolate them from each other. In this way, the spraying of washing water and the production spraying of sterilizing water are completely independent. Therefore, in terms of timing, the production spraying of sterilizing water is completed independently by itself, and there is no need to start the spraying of washing water. Another benefit of such a setting is that when one of the supply water circuits fails, it will not affect the other supply water circuits. Even if one of the supply water circuits fails, the basic flushing function can be maintained, which increases the service life and reliability of the urinal.

[0048] In one embodiment, if Figure 7 As shown, the water outlet of the first flushing device 210 and the water outlet of the second flushing device 220 are integrated on the sensing probe of the control system. That is to say, by adopting the sensing probe and the water spraying assembly with the sensing spraying integrated design, the volume is small and no extra space is occupied. At the same time, the integrated structural design can also have a higher strength and increase the reliability of use.

[0049] It should also be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, commodity or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, commodity or device. In the absence of more restrictions, the elements defined by the sentence "comprises a ..." do not exclude the existence of other identical elements in the process, method, commodity or device including the elements.

[0050] The above are only embodiments of the present application and are not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included within the scope of the claims of the present application.
