Because the urinal body 3 has many types of structures, and is not the focus of the new type of improvement, it will not be described in detail, and the implementation is not limited to the diagram style.

The temperature measuring device 5 can be controlled and activated to detect temperature changes of the receiving areas 311 of the main body portion 31 and generate a temperature measurement data correspondingly. In this embodiment, the temperature measuring device 5 is an infrared temperature measuring device installed on the top side area of the body portion 31, and can perform temperature detection downward toward the inner surface of the body portion 31. Because there are many types of temperature measuring devices 5, the implementation is not limited to the above types, and the position mounted on the body portion 31 is not limited to this. The installation position can be adjusted according to the various designs of the urinal body 3, as long as it can be measured The temperature of the receiving areas 311 on the inner surface of the body portion 31 changes.

The urine volume detection device 6 includes a receiving container 61 detachably mounted on the snap ring portion 32 and used to connect to the urine discharge pipeline 900, and a communication container mounted on the receiving container 61. A solenoid valve 62 and a water level detector 63 installed in the receiving container 61. The receiving container 61 has a receiving slot body 611 with an opening facing upward and used to receive urine discharged from the latching ring portion 32, and two protruding upwards from the left and right sides of the receiving slot body 611, respectively. The card inserting arm portions 612 are detachably horizontally inserted into the card inserting slots 320 respectively, and the receiving container 61 can be easily disassembled to the card through the card inserting arm portions 612.接 环 部 32。 The ring portion 32. The solenoid valve 62 can be driven to open, and the urine in the receiving container 61 is discharged into the urine discharge line 900. The water level detector 63 can detect the urine volume contained in the receiving container 61, and correspondingly generates a urine volume detection signal.

In this embodiment, the receiving container 61 is made of transparent material, and the water level detector 63 is an optical water level detector installed on the outer surface of the receiving container 61. However, in implementation, in other embodiments of the present invention, the water level detector 63 may also be a capacitive water level detector provided on the outer surface of the receiving container 61, or an ultra-high level detector provided in the receiving container 61. Sonic water level detector. Since there are many types of water level detectors 63, the implementation is not limited to the above aspects.

Referring to FIGS. 1, 3 and 4, the control device 7 is integrated with the flushing device 4 and includes a user sensor 71 and a flushing controller 72. The user sensor 71 can detect whether there is a user within a specific distance in front of the urinal body 3, and will start to generate a trigger signal when a user is detected to be present, and when no user is detected, Stop generating the trigger signal.

The flushing controller 72 is connected to the user sensor 71, the water outlet valves 41 of the flushing device 4, the temperature measuring device 5, the water level detector 63 and the solenoid valve 62. The flushing controller 72 includes a plurality of flushing times corresponding to different urine volumes, and corresponding data of the receiving areas 311 and the water outlet valves 41. The flushing controller 72 receives and analyzes the urine volume detection signal, obtains the urine volume in the receiving container 61, and compares the corresponding flushing time according to the urine volume. The flushing controller 72 also receives and analyzes the temperature measurement data to obtain the temperature changes of the receiving areas 311. When the temperature change of one receiving area 311 is greater than a predetermined threshold, for example, it exceeds 15 ° C, the comparison is performed. The water outlet valve 41 corresponding to the receiving area 311 is exited.

In addition, the flush controller 72 has a built-in standby mode 721, a pre-flush mode 722, and a flush mode 723. When the standby mode 721 is triggered by the trigger signal, the pre-flush mode 722 is activated preferentially. A pre-flush time is continuously activated, and when the trigger signal disappears, the flushing mode 723 is switched on and started, and the flushing time is compared, and then switched to the standby mode 721 again.

When the flushing controller 72 is in the standby mode 721, it controls the user sensor 71 to continuously detect whether a user appears in front of the urinal body 3. When the flushing controller 72 switches to the pre-flushing mode 722, it will control the solenoid valve 62 to open for a first opening time that exceeds the pre-flushing time, and will control the water from the flushing device 4. The valve 41 is opened and the pre-flush time is continued, so that the flushing device 4 releases water to wet the inner surface of the urinal body 3 and reduce the degree of urine adhesion. When the flushing controller 72 switches to the flushing mode 723, it controls the flushing valves 41 according to the flushing time and the flushing valve 41 corresponding to each receiving area 311 whose temperature change is greater than a predetermined threshold. Start the flushing time, and control the solenoid valve 62 to open for a second opening time greater than the flushing time, to make the solenoid valve 62 empty the urine in the receiving container 61, and drain the flushing device 4 The released liquid is controlled to close the solenoid valve 62 again until the second opening time is over.

When the new water-saving urinal 100 is used, the flushing controller 72 switches from the standby mode 721 to the pre-flush mode when the user sensor 71 detects that there is a user in front of the urinal body 3. 722. Then, the flushing controller 72 continuously analyzes the urine volume detection signal to compare the corresponding flushing time, and continuously analyzes the temperature measurement data to obtain each receiving area 311 whose temperature change is greater than the predetermined threshold. And the water outlet valve 41 corresponding to the aforementioned receiving area 311. Then, when the user sensor 71 stops generating the trigger signal, the solenoid valve 62 is controlled to open the second opening time, and each of the water outlet valves 41 controlled to be opened to flush the time, so that it is opened. The water liquid released from each water outlet valve 41 can be used to flush the urinal body 3 with a receiving area 311 for receiving urine. Therefore, the amount of flushing water will be determined according to the measured amount of urine. When the amount of urine is large, the flushing time will be longer. When the amount of urine is small, the flushing time will be shorter, and only the urine body 3 will be contaminated with urine. The receiving area 311 is flushed.

In order to prevent urine scale from attaching to the receiving container 61 and the solenoid valve 62, after the water-saving urinal is used for a period of time, the receiving container 61 can be detached from the urinal body 3 so that the receiving container 61 and The solenoid valve 62 is cleaned, and after being cleaned, the urinal body 3 is replaced and used again, which is quite convenient.

In this embodiment, the water-saving urinal 100 determines the flushing time according to different urine volumes, and decides whether to flush the receiving area 311 according to the temperature change of each receiving area 311. In another implementation aspect, it is not necessary to detect the temperature change to determine which receiving area 311 is to be flushed. After analyzing the urine volume to determine the flushing time, the entire inner surface of the urinal body 3 is performed. Flushing water can also save water.

In addition, in this embodiment, the receiving container 61 is detachably snap-fixed to the snap ring portion 32 of the urinal body 3 through the snap-in arm portions 612. In other embodiments, the detachable connection structure between the receiving container 61 and the urinal body 3 is not limited to this, and the connection can be performed by screwing. Because there are many detachable assembly structures between the two components, the implementation is not limited to the above.

In summary, through the structural design of the flushing device 4, the urine volume detection device 6, and the control device 7, the required flushing time can be determined according to the amount of urine of the user, that is, according to the urine The amount of liquid determines the amount of water when flushing, and can achieve the purpose of saving water. Furthermore, it can further cooperate with detecting the temperature change of each receiving area 311 on the inner surface of the urinal body 3 to determine whether the flushing design is performed for these receiving areas 311. The flushing can be performed only for the receiving areas 311 that are stained with urine. Water washing can further save water consumption under the condition that the basic cleaning effect of the urinal body 3 is maintained, which is a very convenient and practical urinal design. Therefore, the purpose of this new model can be achieved.

However, the above are only examples of the new model. When the scope of implementation of the new model cannot be limited by this, any simple equivalent changes and modifications made in accordance with the scope of the patent application of the new model and the content of the patent specification are still Within the scope of this new patent.
