[0002] This application relates to the field of bathroom technology, and more specifically, to an intelligent health detection method. Background Technology

[0003] Urinals are an important sanitary facility in public restrooms, and most currently have an automatic flushing function, which washes away stains and ensures cleanliness. However, current automatic flushing systems rely solely on human body sensors, which can lead to sewage overflow and environmental pollution when the urinal becomes clogged.

[0004] In addition, existing urinals do not have corresponding urine health detection functions, making it difficult for users to obtain their urine health information based on the urine they urinate in, thus making it inconvenient to make a judgment on their health and determine whether further examination is needed based on this information. Summary of the Invention

[0007] The flushing control method includes the following steps:

[0008] The first distance between the microwave sensing component and the target object is obtained as detected by the microwave sensing component, wherein the target object is an effective target that can be detected by the microwave sensing component.

[0009] The first distance is judged according to a preset blockage distance threshold. If the first distance is less than the preset blockage distance threshold, the flushing component is controlled not to flush. The preset blockage distance threshold is not greater than the distance between the front end of the main body and the microwave sensing component, and is greater than the distance between the microwave sensing component and the water accumulation in the toilet when the toilet is blocked.

[0010] If the first distance is greater than the preset blockage distance threshold, the first distance is judged according to the first distance threshold; if the first distance is less than the first distance threshold, the flushing component is controlled to flush; the first distance threshold is greater than the distance between the foremost part of the body and the microwave sensing component.

[0011] The detection method includes the following steps:

[0012] When a stream of urine appears within the detection range of the microwave sensing component, the reflected signal of the urine stream is detected;

[0022] Optionally, the morphological data includes some or all of the following parameters: the flow rate of the urine column, the thickness of the urine column, and the discontinuity of the urine column.

[0023] Optionally, the process of evaluating the morphological data to obtain the user's urinary health information is as follows: the discontinuity parameter of the urine column is processed, and when the number of discontinuities of the urine column is higher than a certain value, it is determined to be unhealthy.

[0024] Optionally, the process of evaluating the morphological data to obtain the user's urine health information is as follows: the flow velocity parameter of the urine column is processed, and when the average flow velocity of the urine column is lower than the pre-statistical health value, it is determined to be unhealthy.

[0025] Optionally, the process of evaluating the morphological data to obtain the user's urine health information is as follows: the average reflected wave energy of the reflected signal is correlated with the thickness parameter of the urine column, the average reflected wave energy of the reflected signal is processed, and when the average reflected wave energy is lower than the pre-statistical health value, it is determined to be unhealthy.

[0026] Optionally, the flushing control method further includes the following steps: acquiring the first distance between the microwave sensing component and the target object detected by the microwave sensing component again, judging the first distance according to a second distance threshold value, and controlling the flushing component to flush again if the first distance is greater than the second distance threshold value; the second distance threshold value is greater than the first distance threshold value.

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0042] Example 1

[0043] Figure 1 This is a cross-sectional view of a urinal according to an embodiment of this application.

[0044] like Figure 1 As shown, the urinal provided in this embodiment includes a main body 10 and a controller (not shown), and also includes a microwave sensing component 20 connected to the controller and a flushing component 30 disposed on the main body. The controller is signal-connected to the microwave sensing component and the flushing component respectively, and is used to acquire detection data from the microwave sensing component and control the flushing component to flush based on the detection data.

[0045] The microwave sensing component is located at the rear of the water trap 11 of the main body. Its position is on a plane that refers to the preset water level when water accumulates in the water trap. The plane can also be finely adjusted according to the actual situation and on-site calibration, so that the plane is lower or higher than the water level by a certain correction value.

[0046] The microwave sensing component includes an antenna module, which includes a transmitting antenna for transmitting electromagnetic waves and a receiving antenna for receiving reflected electromagnetic waves. The transmitting antenna is used to transmit electromagnetic waves forward. After the electromagnetic waves are reflected, they are detected by the receiving antenna and generate the aforementioned detection data, which is then sent to the controller.

[0047] The microwave sensing component is located on the rear wall of the main body, and a cavity is provided on the rear wall to accommodate the microwave sensing component. The cavity can actually be regarded as a recessed structure on the rear wall. The wall thickness of the cavity is relatively thin, that is, thinner than the adjacent parts. By setting this cavity, it is convenient to install the microwave sensing component. In addition, a thick wall will affect the transmission distance of electromagnetic waves, but too thin a wall will affect the overall strength of the urinal. By setting this cavity, the overall strength of the urinal can be guaranteed while avoiding excessive impact on the transmission of electromagnetic waves.

[0048] like Figure 2a As shown, under normal circumstances, without water blockage, when the water inside does not obstruct the microwave emission path, the electromagnetic waves emitted by the microwave sensing component penetrate the air, ceramic, and air in sequence to reach the human body. The dielectric constants of air and ceramic are not much different, but the dielectric constants of air and human body are much different. The human body reflects a large amount of microwaves, so the microwave sensing component can detect the spatial position of the human body normally.

[0049] In the case of water blocking, such as Figure 2b As shown, the water in the urinal's trap blocks the electromagnetic wave's transmission path. The electromagnetic wave passes through the air, ceramic, and water in sequence, making it almost impossible for it to reach the human body. The dielectric constants of air and ceramic are not much different, so microwaves can penetrate them. However, the dielectric constants of ceramic and water are much different, so microwaves can hardly penetrate the water, making it impossible to accurately detect the human body.

[0050] Based on the above analysis, the detection data output by the microwave sensing component is different when the urinal is blocked and when it is not blocked. After receiving the above detection data, the controller outputs a corresponding flushing control signal to the flushing component. The flushing control signal is used to control the flushing component to flush normally when it detects a human body approaching when the urinal is not blocked, and to control the flushing component to avoid flushing when there is a blockage.

[0051] As can be seen from the above technical solution, this embodiment provides a urinal, including a main body, a flushing assembly, a controller, and a microwave sensing assembly connected to the controller. The controller is configured to acquire detection data from the microwave sensing assembly to control the flushing assembly to flush. The microwave sensing assembly has an antenna module for transmitting and receiving electromagnetic waves. The urinal has a preset water level for when a blockage occurs. The antenna module is positioned no higher than the preset water level so that when the water level reaches the preset level, the electromagnetic waves emitted by the antenna module are blocked by the water and can hardly reach the human body. The microwave sensing assembly sends the detection data of the urinal being blocked to the controller, and the controller controls the flushing assembly not to flush. Through the above solution, the flushing assembly can be prevented from continuing to flush when a blockage occurs, thereby preventing sewage overflow.

[0052] In another specific embodiment of this application, the controller further includes an information output module (not shown) for timely outputting corresponding blockage information when water blockage occurs, so as to remind managers to take timely measures.

[0053] For example Figure 3 The diagram shown is a flowchart of a health detection method according to an embodiment of this application.

[0054] S11. Detect the reflection signal of the urine column.

[0055] When a stream of urine appears within the detection range of the microwave sensing component, the reflected signal of the urine stream is detected.

[0056] S12. Calculate the morphological data of the urine column based on the reflected signal.

[0057] The morphological data here includes, but is not limited to, some or all of the parameters of urine column velocity, thickness, and discontinuity. Specific morphology is as follows: Figure 4 As shown.

[0058] S13. Estimate the health status of urine based on morphological data.

[0059] This involves processing morphological data based on a urine health status assessment algorithm to obtain the user's urine health information. By detecting the continuity of the urine column, a higher number of interruptions is considered unhealthy. Similarly, for urine column flow velocity, an average flow velocity lower than a pre-calculated healthy value is also considered unhealthy. Finally, for urine column thickness, reflected wave energy can be used as a reference; an average reflected wave energy lower than a pre-calculated healthy value is considered unhealthy.

[0060] This embodiment can obtain the user's urination health information by judging the morphology data of the user's urine. If the urinal has an information output module, the urination health information can be output so that the user can understand his / her health status in a timely manner.

[0061] Accordingly, the microwave sensing component may also include a urine column detection module for detecting urine column morphology data. The urine column detection module is used to output the morphology data of the urine column to the controller. The morphology data includes, but is not limited to, some or all of the flow rate parameters, thickness parameters, and discontinuity parameters of the urine column.

[0062] The controller then assesses the person's urinary health based on this morphological data, thereby obtaining urinary health information. After obtaining this urinary health information, the controller outputs it to the aforementioned information output module, which then outputs the urinary health information to the user. This allows the user to conveniently obtain their own urinary health information, enabling them to make judgments about their physical health and determine whether further examinations are necessary.

[0063] Example 2

[0064] This embodiment provides a flushing control method, which is applied to the urinal provided in the previous embodiment, specifically to the controller within the urinal. Regarding the detection data from the microwave sensing component, the microwave sensing component can detect when there is no water accumulation. Figure 5a The solid line indicates the distance to objects, while the dashed line indicates that objects in the water-filled area cannot be detected. Figure 5b As shown, after the microwave is emitted, it is largely reflected back by the water and cannot penetrate the water. The microwave continuously detects the water. Whether there are people or not within the detection range, the detection distance data of the microwave sensing component will change accordingly as the water level rises.

[0065] like Figure 6 As shown, the flushing control method provided in this embodiment includes the following steps:

[0066] S21. Obtain the first distance between the urinal and the target object.

[0067] The first distance here refers to the distance between the microwave sensing component and the target object, which is generally a human body or urine. The first distance refers to the closest distance between the microwave sensing component and the target object, or the distance between the closest point of the microwave sensing component and the target object.

[0068] S22. Control the flushing assembly based on the first distance.

[0069] During implementation, the first step is to determine the first distance, which involves comparing it with a preset blockage distance threshold A. The preset blockage distance threshold A is no greater than the distance between the front edge of the urinal body and the microwave sensing component, and greater than the distance between the microwave sensing component and the water accumulation in the urinal when a blockage occurs.

[0070] When the first distance is less than the preset blockage distance threshold A, it is determined that the urinal is blocked. At this time, the flushing component is controlled not to flush in order to avoid sewage overflow.

[0071] Through the above control, it is possible to accurately determine whether a blockage has occurred and control the action of the flushing component according to the blockage situation. That is, the controller stops flushing when flushing is in progress and refuses to execute the corresponding flushing command when flushing has not yet started, so as to avoid sewage overflow.

[0072] In one specific implementation of this embodiment, the following steps are also included: Figure 7 As shown:

[0073] S23. Control the flushing assembly to perform pre-flushing.

[0074] By re-evaluating the first distance, if the first distance is greater than the preset congestion distance threshold A and less than the first distance threshold T_in, then... Figure 8 As shown, the flushing assembly is controlled to pre-flush, or pre-wet, the surface of the urinal. This pre-wetting process prevents urine from directly contacting the surface and facilitates thorough rinsing after flushing.

[0075] In another specific embodiment of this example, the following steps are also included: Figure 9 As shown.

[0076] S24. Control the flushing assembly to flush again.

[0077] When the first distance exceeds the second distance threshold T_out, the flushing component is controlled to flush again. This typically occurs when the user leaves after urinating; in this case, the flushing component is controlled to flush again to clean the urinal surface. By flushing again, the urinal is cleaned, keeping it hygienic and preventing dirt from accumulating on its surface.
