DETAILED DESCRIPTION

[0037] In order to make the purpose, technical solution and advantages of the utility model clearer, the technical solution of the utility model will be described in detail below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0038] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0039] Combine the following Figures 1 to 7 A toilet flushing system provided in an embodiment of the present application is described in detail through specific embodiments and application scenarios.

[0040] Reference Figure 1 , Figure 2 As shown, the present application provides a toilet flushing system, including a toilet body 100, a toilet cover 200, a flushing device, an image acquisition device 300, a shielding member 400, a driving member 500 and a controller 600 (refer to Figure 7 As shown). Exemplarily, the toilet body 100 can provide an installation base for the toilet cover 200, the flushing device, the image acquisition device 300, the shielding member 400, the driving member 500 and the controller 600. In some embodiments, the controller 600 is installed on the toilet body 100 or the toilet cover 200, and each toilet is provided with a controller 600. It can be understood that the controller 600 is an information processing module, which needs to control the flushing device, the image acquisition device 300 and the driving member 500 to work in coordination. Therefore, in order to ensure the normal function of the toilet, the controller 600 needs to be waterproofly installed.

[0041] In some embodiments, reference Figure 1 , Figure 2 As shown, the controller 600 can also be installed at other locations, for example, the controller 600 is installed on an indoor wall or a machine room, and the controller 600 is used to communicate with the image acquisition device 300, the driving member 500 and the flushing device (refer to Figure 7 As shown), so as to transmit information thereto. The control device can control the drive member 500, the flushing device and the image acquisition device 300 to work in coordination. The controller 600 can be installed in an area outside the toilet body 100, and interact with the drive member 500, the flushing device and the image acquisition device 300 in a wireless or wired manner. It is understandable that in the case where a large number of toilets are required in hotels, public toilets, etc., by setting the controller 600 indoors or in a machine room, multiple toilets can be controlled by one controller 600 to work, thereby reducing costs. On the other hand, concentrating the controller 600 in a machine room or indoors can effectively prevent users from directly contacting the controller 600, which is beneficial to prevent privacy and security issues that arise when the data of the controller 600 is modified. It is understandable that since the installation position of the controller 600 can be adjusted according to the needs of use, the specific installation position of the controller 600 is not shown in the structural diagram of this embodiment.

[0042] It is understandable that the controller 600 has a wireless or wired communication function, and the controller 600 has a processing module that can compare and analyze the image, thereby controlling the flushing device according to the comparison and analysis results. In some embodiments, the controller 600 is a single chip microcomputer or an embedded computer.

[0043] Reference Figure 1 , Figure 2 As shown, the toilet body 100 has a cylinder space 110. It is understandable that the toilet body 100 includes an opening, which is connected to the cylinder space 110, and excrement can enter the cylinder space 110 through the opening. In some schemes, the toilet cover 200 is movably arranged on the toilet body 100. When the toilet cover 200 moves relative to the toilet body 100, the opening can be closed or opened, thereby achieving the closure or opening of the toilet body 100. In some embodiments, the toilet cover 200 is detachably installed on the toilet body 100 to facilitate the disassembly of the toilet cover 200, so as to replace different toilet covers 200. Exemplarily, a functional module is provided on the toilet cover 200, and by replacing different toilet covers 200, the toilet can achieve different functions.

[0044] In some schemes, the flushing device is used to provide a flushing liquid to flush the cylinder space 110. In some embodiments, the flushing device is arranged on the toilet body 100. Exemplarily, the flushing device includes a water tank, the water tank is connected to a water pipe, and the water tank is connected to the cylinder space 110, and an opening and closing device is arranged in the water tank. When the opening and closing device is opened, the water in the water tank will be discharged into the cylinder space 110, thereby flushing the cylinder space 110. When the water in the water tank is emptied, the opening and closing device will automatically close so that water can be stored in the water tank through the water pipe. It can be understood that in this embodiment, the opening and closing device can be a solenoid valve or other components. By controlling the opening time when the solenoid valve is triggered, the water in the water tank can be discharged, and the water tank can be closed after the water in the water tank is discharged.

[0045] In some embodiments, part of the flushing device is arranged outside, and part of the flushing device is arranged in the toilet body 100 and / or the toilet cover 200. Exemplarily, the flushing device includes a tap water pipe, a water pump and a nozzle. The tap water pipe is drawn from the outside to the water pump. The water pump can be installed in the toilet body 100 or outside. The nozzle is installed in the toilet body 100 and / or the toilet cover 200. The water pump is connected to the controller 600 for communication. The water pump can be controlled to work by the controller 600. When the water pump is working, the water in the tap water pipe can be pressurized and transported to the nozzle, thereby flushing the space 110 in the cylinder.

[0046] In some embodiments, reference Figure 1 , Figure 2 As shown, the image acquisition device 300 is used to acquire images under the control of the controller 600. The image acquisition device 300 is disposed on the toilet cover 200. Specifically, the image acquisition device 300 is disposed on the side of the toilet cover 200 facing the toilet body 100. When the toilet cover 200 closes the toilet body 100, the image acquisition device 300 will be located in the cylinder space 110. When the image acquisition device 300 is controlled by the controller 600, the image acquisition device 300 located in the cylinder space 110 can acquire images to take photos of the cylinder space 110, thereby performing a comparative analysis of the cleanliness of the cylinder space 110.

[0047] In some embodiments, the image acquisition device 300 includes a camera, such as a visible light camera, which can provide high-resolution and true-color images to facilitate identification of details and accurately determine whether the cylinder space 110 is rinsed clean. In some embodiments, the camera includes a visible light camera and an infrared camera. During use, the cylinder space 110 is imaged and compared by a visible light camera and an infrared camera, respectively. Combining the image comparison results collected by these two cameras, it is possible to comprehensively judge whether the cylinder space 110 is thoroughly rinsed clean, thereby improving the accuracy of the judgment. In addition, the infrared camera can capture and compare images under low-light conditions, so that the comparison accuracy is higher and it is adaptable to a variety of environments.

[0048] In some embodiments, reference Figure 4 , Figure 5 As shown, the shielding member 400 is movably disposed on the toilet cover 200, and the shielding member 400 can shield the image acquisition device 300, so that the image acquisition device 300 cannot take pictures of the outside world, so as to protect the privacy of the user. It can be understood that the shielding member 400 is movably disposed on the toilet cover 200, and the shielding member 400 can be directly connected to the toilet cover 200, or the shielding member 400 can be indirectly connected to the toilet cover 200. For example, when the toilet cover 200 is connected to other components, the shielding member 400 is movably connected to the other components (refer to Figure 5 ). In some embodiments, when the toilet cover 200 opens the toilet body 100, that is, when the image acquisition device 300 is located outside the cylinder space 110, the shielding member 400 shields the image acquisition device 300, thereby preventing the image acquisition device 300 from capturing external images. When the toilet cover 200 closes the toilet body 100, the image acquisition device 300 is located in the cylinder space 110. At this time, the shielding member 400 opens the image acquisition device 300, so that the image acquisition device 300 can capture images of the cylinder space 110, so as to compare the cylinder space 110. It can be understood that when the toilet cover 200 closes the toilet body 100, the image acquisition device 300 can only capture images of the cylinder space 110, and cannot capture images outside the cylinder space 110.

[0049] In some embodiments, reference Figure 4 , Figure 5As shown, the shielding member 400 includes a cover plate slidably arranged (indirectly slidably arranged) on the toilet cover 200, and the sliding direction of the cover plate slides from the side close to the image acquisition device 300 to the side away from the image acquisition device 300. In this way, the cover plate can move to the position of the image acquisition device 300 during the sliding process. When the cover plate slides to the image acquisition device 300, it will enter the acquisition area of ​​the image acquisition device 300 and completely cover the area, so that the image acquisition device 300 can only capture the cover plate, but cannot capture other positions, thereby achieving shielding of the image acquisition device 300.

[0050] In some embodiments, the shielding member 400 includes a cover plate (not shown) rotatably disposed on the toilet cover 200. When the cover plate rotates, it can move to the acquisition area of ​​the image acquisition device 300 and completely cover the area, so that the image acquisition device 300 can only capture the cover plate and cannot capture other positions, thereby achieving shielding of the image acquisition device 300.

[0051] In some embodiments, the driving member 500 is used to drive the shielding member 400 to move so that the image acquisition device 300 is blocked or opened. In some embodiments, the shielding member 400 includes a cover plate rotatably arranged on the toilet cover 200, and the driving member 500 includes a motor (not shown in the figure), which is used to drive the cover plate to rotate so that the cover plate can be turned to the acquisition area of ​​the image acquisition device 300 and completely cover the area, so that the image acquisition device 300 can only capture the cover plate, but cannot capture other positions, thereby achieving the shielding of the image acquisition device 300. In some embodiments, the shielding member 400 includes a cover plate slidably arranged on the toilet cover 200, and the driving member 500 protects the electric rod or the screw rod structure, the piston rod or the slider of the electric rod is connected to the cover plate, and the cover plate is driven by the motor to slide relative to the toilet cover 200 or the slider is driven by the screw rod to move, thereby driving the cover plate to slide relative to the toilet cover 200, and when the cover plate slides, the cover plate can slide to the image acquisition device 300 to shield the image acquisition device 300.

[0052] According to an alternative embodiment, referring to Figure 3 , Figure 4As shown, the toilet cover 200 is provided with a protective cover 210, and the protective cover 210 is provided with a shooting port 211. The image acquisition device 300 is located in the protective cover 210 and can be photographed through the shooting port 211. Exemplarily, the protective cover 210 is detachably mounted on the toilet cover 200, for example, the protective cover 210 is bonded to the toilet cover 200 by bolts or glue. It can be understood that the protective cover 210 has a cavity for accommodating the image acquisition device 300, so that the image acquisition device 300 is located in the cavity. When the toilet cover 200 closes the toilet body 100, the protective cover 210 can protect the image acquisition device 300 and reduce the situation where water splashes onto the image acquisition device 300 when the flushing device flushes. While protecting the image acquisition device 300, the protective cover 210 allows the image acquisition device 300 to capture images of the inner space 110 of the cylinder through the shooting port 211. The shooting port 211 is designed to be small, so that the image acquisition device 300 can only capture images within a specific range. By adjusting the size of the shooting port 211 and / or the distance between the image acquisition device 300 and the shooting port 211, the acquisition area of ​​the image acquisition device 300 can just cover the cylinder space 110. This not only meets the image acquisition requirements, but also avoids the acquisition of images of other areas, thereby improving privacy and security. On the other hand, designing a smaller shooting port 211 can also reduce the situation where water splashes into the shooting port 211, thereby further protecting the image acquisition device 300 from water damage.

[0053] In some embodiments, reference Figure 4 , Figure 5 As shown, the photographing port 211 is on the path of the shielding member 400. When the shielding member 400 moves, the photographing port 211 can be blocked. Since the image acquisition device 300 can only acquire the image of the cylinder space 110 through the photographing port 211, the image acquisition device 300 can be blocked by controlling the shielding member 400 to block the photographing port 211.

[0054] According to an alternative embodiment, referring to Figure 4 , Figure 5 As shown, the shooting port 211 is provided with a transparent window 212. Exemplarily, the transparent window 212 is a transparent glass plate or a transparent plastic plate installed at the shooting port 211. By providing the transparent window 212, it is possible to prevent water from entering the shooting port 211 while still allowing the image acquisition device 300 to capture images of the cylinder space 110. The transparent window 212 can effectively prevent water from entering the shooting port 211, so that the image acquisition device 300 is not easily in contact with water during use, thereby ensuring its long-term stable operation.

[0055] According to an optional embodiment, the surface of the transparent window 212 is coated with a hydrophobic coating. By coating the transparent window 212 with a hydrophobic coating, the residual water droplets on its surface can be reduced, thereby ensuring that the image acquisition device 300 is not affected by the residual water droplets when collecting the image of the inner space 110 of the cylinder, and the clarity and authenticity of the image are maintained. This helps to avoid comparison errors caused by residual water droplets, thereby preventing the situation of misjudging whether the toilet is flushed clean. Exemplarily, the hydrophobic coating can be one or more of a fluoride coating, a silane coating, and a nano coating. For example, the hydrophobic coating is a polytetrafluoroethylene coating, and can also be a fluorocarbon resin coating.

[0056] According to an alternative embodiment, referring to Figure 5 , Figure 6 As shown, when the toilet cover 200 closes the toilet body 100, the surface of the transparent window 212 facing the cylinder space 110 gradually tilts toward the cylinder space 110 from one side of the transparent window 212 to the other side. The surface of the transparent window 212 facing the cylinder space 110 gradually tilts toward the cylinder space 110, which means that the surface of the transparent window 212 facing the cylinder space 110 is an inclined surface, and from one side of the transparent window 212 to the other side, the inclined surface gradually tilts toward the cylinder space 110. For example, from Figure 6 From the right side to the left side of the position, the thickness of the transparent window 212 gradually increases, and by increasing the thickness of the transparent window 212, the surface of the transparent window 212 facing the inner cylinder space 110 is an inclined surface. In some embodiments, when the toilet lid 200 is closed, the toilet lid 200 is in a horizontal position. At this time, the transparent window 212 forms a certain angle with the horizontal plane, so that the side of the transparent window 212 close to the inner cylinder space 110 is closer to the inner cylinder space 110 than the other side. When water droplets splash onto the transparent window 212, under the action of gravity, the water droplets will flow along the surface of the transparent window 212 to the side close to the inner cylinder space 110, thereby preventing the water droplets from staying in the middle position of the transparent window 212 and affecting the operation of the image acquisition device 300.

[0057] In some embodiments, the surface of the transparent window 212 facing the cylinder space 110 is closer to the cylinder space 110 and is located outside the image acquisition range of the image acquisition device 300. Since water droplets will be concentrated on the side of the transparent window 212 closer to the cylinder space 110, the side of the transparent window 212 closer to the cylinder space 110 is set outside the acquisition range of the image acquisition device 300, which can prevent water droplets from affecting the image acquisition of the image acquisition device 300. Figure 6 The middle dotted line represents the image acquisition range of the image acquisition device 300 .

[0058] According to an alternative embodiment, referring to Figure 3As shown, the toilet cover 200 is movably provided with a shielding member 220 to shield the image acquisition device 300 under the action of an external force. The shielding member 220 is manually controlled to facilitate the user to choose whether to open the shielding member 220 according to their needs. When the user shields the image acquisition device 300 through the shielding member 220, the image acquisition device 300 is always unable to capture external images, thereby protecting the user's privacy. Exemplarily, the shielding member 220 includes a shielding plate, which is slidably arranged on the toilet cover 200. When the user manually pushes the shielding plate, it can be moved to the position of the image acquisition device 300, thereby shielding the image acquisition device 300 and preventing it from capturing images of the outside world. It can be understood that there is a certain friction between the shielding plate and the toilet cover 200, and when the external force is removed, the shielding plate can stay in the current position. Therefore, the shielding plate can stay at a position of shielding the image acquisition device 300 or a position of opening the image acquisition device 300 under the action of an external force, thereby manually controlling whether the image acquisition device 300 performs image acquisition.

[0059] In some embodiments, reference Figure 3 As shown, the shielding member 400 is parallel to the sliding direction of the shielding member 220, and the shielding member 400 is located on the side closer to the image acquisition device 300, while the shielding member 220 is located on the side away from the image acquisition device 300. When the shielding member 400 and the shielding member 220 slide at the same time, they will not interfere with each other, and both can slide to the position of shielding the image acquisition device 300 at the same time. Since the shielding member 400 is closer to the image acquisition device 300, even after shielding the image acquisition device 300 at the same time, the shielding member 220 is manually pushed to the side away from the image acquisition device 300, and the image acquisition device 300 cannot capture external images. Only when the toilet cover 200 closes the toilet body 100, the shielding member 400 will open the image acquisition device 300 under the drive of the driving member 500, so as to capture external images. This design not only satisfies the requirement of manually controlling whether the image acquisition device 300 can capture external images, but also ensures that the image acquisition device 300 will not capture external images when the toilet lid 200 is opened, thereby providing higher privacy protection.

[0060] According to an alternative embodiment, referring to Figure 2 As shown, the image acquisition device 300 is located at the center of the side surface of the toilet cover 200 facing the toilet body 100. That is, when the toilet cover 200 is closed, the image acquisition device 300 is located in the middle of the opening of the inner cylinder space 110, so that the image of the inner cylinder space 110 can be better acquired, thereby improving the accuracy of the cleanliness detection of the inner cylinder space 110.

[0061] According to an optional embodiment, the image acquisition device 300 includes a fill light. The fill light can be used to illuminate the cylinder space 110, so that the image acquisition device 300 can capture clearer images to increase the accuracy of image contrast. It is understandable that when the toilet lid 200 is closed, the light in the cylinder space 110 may be insufficient, and the fill light can be used to supplement the light. In some embodiments, there are multiple fill lights, and their irradiation directions are different, so that the cylinder space 110 can be illuminated in multiple directions to avoid lighting blind spots. In other embodiments, the irradiation angle of the fill light is different from the shooting angle of the image acquisition device 300, thereby avoiding the situation where the light of the fill light is reflected on the water surface in the cylinder space 110, resulting in the image acquisition device 300 being unable to take clear pictures.

[0062] According to an optional embodiment, one of the toilet cover 200 and the toilet body 100 is provided with a switch member 230 (combined with Figure 7 As shown), the other is provided with a triggering member for triggering the switch member 230. When the toilet cover 200 closes the toilet body 100, the triggering member triggers the switch member 230, and the switch member 230 is connected to the controller 600 for communication. The switch member 230 can provide a signal when the toilet cover 200 closes the toilet body 100, so that the controller 600 responds to the signal and controls the driving device, thereby opening the image acquisition device 300, so that the image acquisition device 300 can capture images of the cylinder space 110. It can be understood that the controller 600 can also respond to the signal of the switch member 230 to power on or off the image acquisition device 300, so that when the toilet cover 200 opens the toilet body 100, the image acquisition device 300 is powered off by the controller 600 to prevent the image acquisition device 300 from capturing external images when it is opened. It can be understood that the switch component 230 can be installed on the side of the toilet cover 200 facing the toilet body 100, or on the side of the toilet body 100 facing the toilet cover 200. The specific installation position can be selected according to actual needs. In this embodiment, the specific installation position of the switch component 230 is not limited, so the structural diagram of the switch component 230 is not given in the figure.

[0063] In some embodiments, the switch member 230 is a contact switch, and the trigger member is an abutment block provided on the toilet body 100. When the toilet cover 200 closes the toilet body 100, the contact switch contacts the abutment block, thereby triggering the contact switch, and at this time the contact switch sends a signal to the controller 600, and the controller 600 can control the image acquisition device 300 to work after receiving the signal. By providing the abutment block, the contact switch can only be triggered by the abutment block, thereby preventing the user from accidentally touching the contact switch when wiping or cleaning the toilet cover 200.

[0064] In other embodiments, the switch 230 may be a proximity switch or a light sensor switch. When the toilet cover 200 closes the toilet body 100, these switches will be triggered, and the proximity switch or light sensor switch will send a signal to the controller 600, so that the image acquisition device 300 can work.

[0065] According to an optional embodiment, the toilet body 100 and / or the toilet cover 200 is provided with an operation panel 120 (refer to Figure 7 ), the operation panel 120 is communicatively connected with the controller 600. Through the operation panel 120, the user can control the flushing volume and flushing time of the flushing device to meet different usage requirements. The operation panel 120 can also be used to control the image acquisition device 300 to completely close it, so that the image acquisition device 300 will not work during the use of the toilet. This design meets various usage requirements and provides greater flexibility and privacy protection. This embodiment does not limit the specific installation position of the operation panel 120, and the structural diagram of the operation panel 120 is not shown in the figure.

[0066] According to an optional embodiment, when the toilet cover 200 closes the toilet body 100, the toilet cover 200 and / or the toilet body 100 sends a closing signal; the controller 600 controls the flushing device to flush for a preset time in response to the closing signal, and controls the shielding member 400 to open the image acquisition device 300, and controls the image acquisition device 300 to acquire an image, wherein the controller 600 has an image comparison module, and the image comparison module compares the image acquired by the image acquisition device 300 with the original image, and the controller 600 controls the working state of the flushing device based on the comparison result of the image comparison module. Exemplarily, when the toilet cover 200 closes the toilet body 100, the switch 230 is triggered, and the switch 230 sends a closing signal and is responded by the controller 600. This solution can automatically flush when the toilet cover 200 is closed, so as to prevent the aerosol generated during flushing from being emitted to the outside, thereby reducing the risk of harmful substances such as viruses being emitted to the outside of the cylinder space 110 during use. It can be understood that the processes and procedures in which the controller 600 responds to the shutdown signal and controls the flushing device to flush, the image captured by the image acquisition device 300 to compare with the original image, the shielding member 400 to open, and the image acquisition device 300 to capture an image are all prior arts and will not be described in detail in this embodiment.

[0067] Working process: When the toilet lid 200 is in an open state, the controller 600 controls the shielding member 400 and the camera device to be closed to avoid collecting images when not needed.

[0068] When the toilet lid 200 is closed, the controller 600 receives this signal and triggers the flushing device to perform an automatic flush (a flushing with a set time so that the toilet body 100 is flushed for a period of time).

[0069] After the flushing is completed, wait for a few seconds to ensure that the flushing liquid has drained out and the flushing liquid remaining in the cylinder space 110 is stabilized.

[0070] The controller 600 controls the shielding member 400 to open, and controls the image acquisition device 300 to open, so as to acquire images of the cylinder space 110 , and compare the acquired images with the preset original images (ie, images taken when the cylinder space 110 is clean).

[0071] Comparison result processing: a. Successful identification: If the comparison result shows that the state of the inner space 110 is similar or consistent with the original image, it is determined that the toilet has been flushed clean, and the controller 600 will end the current process. This means that the image acquisition device 300 stops working, the flushing device stops flushing, and the shielding member 400 shields the image acquisition device 300. .

[0072] b. Recognition failure: If the comparison result shows that there are still residues in the cylinder space 110 or it is significantly different from the original picture, it is determined that the toilet has not been flushed clean this time. At this time, the controller 600 will control the flushing device to flush the cylinder space 110 again. After the flushing is completed, the process of taking pictures, comparing and identifying is repeated. If the recognition fails again, the above steps can be repeated once. If the recognition fails three times in a row, the controller 600 transmits a signal to notify the management staff for processing.

[0073] The above description is only a specific implementation of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, which should be included in the protection scope of the present invention.
