DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] Embodiment 1 Figure 1 This is a cross-sectional view of a urinal according to an embodiment of the present application.

[0020] like Figure 1 As shown, the urinal provided in this embodiment includes a body 10 and a controller (not shown), and also includes a microwave sensing component 20 connected to the controller and a flushing component 30 arranged on the body. The controller is respectively connected to the microwave sensing component and the flushing component for signal connection, and is used to obtain detection data from the microwave sensing component, and control the flushing component to perform flushing based on the detection data.

[0021] The microwave sensing component is arranged at the rear part of the water trap 11 of the main body, and its position is located in such a plane. The plane refers to the preset water level when water accumulates in the water trap. The plane can also be fine-tuned according to actual conditions and on-site calibration conditions so that the plane is lower than the water level or higher than the water level by a certain correction value.

[0022] 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 being reflected, the electromagnetic waves are detected by the receiving antenna and generate the aforementioned detection data, and the detection data is sent to the controller.

[0023] The microwave induction component is located on the rear wall of the body, and a cavity for accommodating the microwave induction component is provided on the rear wall. The cavity can actually be regarded as a recessed structure of the rear wall. The wall thickness of the cavity is thinner, that is, thinner than the adjacent parts. The installation of the microwave induction component can be facilitated by providing the cavity. In addition, a thicker wall thickness will affect the transmission distance of the electromagnetic wave, but too thin a wall thickness will affect the overall strength of the urinal. By providing the cavity, the overall strength of the urinal can be ensured while avoiding excessive influence on the transmission of the electromagnetic wave.

[0024] like Figure 2aAs shown, under normal circumstances, when there is no water blockage, when the accumulated water inside does not block the microwave emission path, the electromagnetic waves emitted by the microwave sensing component penetrate the air, ceramic, air in turn, and 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 quite different. The human body reflects a large amount of microwaves, so the microwave sensing component can normally detect the spatial position of the human body.

[0025] In case of water blocking, Figure 2b As shown, at this time, the accumulated water in the water trap of the urinal blocks the emission path of the electromagnetic waves. The electromagnetic waves pass through the air, ceramics and water in turn and can hardly reach the human body. The dielectric constants of air and ceramics are not much different, so microwaves can penetrate. However, the dielectric constants of ceramics and water are very different, so microwaves can hardly penetrate water, resulting in the inability to accurately detect the human body.

[0026] Based on the above analysis, the detection data output by the microwave sensing component is different when there is water blocking and when there is no water blocking. After receiving the above detection data, the controller outputs a corresponding flushing control signal to the flushing component based on the detection data. The flushing control signal is used to control the flushing component to flush normally when it detects that a human body is approaching when the urinal is not blocked, and control the flushing component to avoid flushing when there is water blocking.

[0027] It can be seen from the above technical scheme that this embodiment provides a urinal, including a body, a flushing assembly, a controller, and a microwave sensing assembly connected to the controller, the controller is configured to obtain detection data of 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 when blockage occurs, the position of the antenna module is not higher than the preset water level, so that when the water level of the urinal reaches the preset water 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 when the urinal is blocked to the controller, and the controller controls the flushing assembly not to flush. Through the above scheme, it can be avoided that the flushing assembly continues to flush when water blockage occurs, thereby preventing sewage from overflowing.

[0028] In addition, in a specific embodiment of the present 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 management personnel to take timely measures.

[0029] Another example Figure 3 Shown is a flow chart of a health detection method according to an embodiment of the present application.

[0030] S11. Detect the reflection signal of the urine column.

[0031] When a urine column appears within the detection range of the microwave sensing component, a reflection signal of the urine column is detected.

[0032] S12. Calculate the morphological data of the urine column according to the reflection signal.

[0033] The morphological data here include but are not limited to part or all of the flow rate parameters, thickness parameters and discontinuity parameters of the urine column. Figure 4 shown.

[0034] S13. Estimate the healthy status of urine based on the morphological data.

[0035] That is, the morphological data is processed based on the urine health status assessment algorithm to obtain the user's urine health information. By detecting the continuity characteristics of the urine column, when the number of interruptions of the urine column is higher than a certain value, it is judged as unhealthy; for the urine column flow rate characteristics, when the average flow rate is lower than the previously calculated healthy value, it is judged as unhealthy; for the urine column thickness parameters, the reflected wave energy can be referred to. When the average reflected wave energy is lower than the previously calculated healthy value, it is judged as unhealthy.

[0036] This embodiment can obtain the user's urine health information by judging the user's urine shape data. If the urinal has an information output module, the urine health information is output, so that the user can understand his or her health status in time.

[0037] Correspondingly, the microwave sensing component may further include a urine column detection module for detecting urine column morphological data, the urine column detection module being used to output the urine column morphological data to the controller, the morphological data including but not limited to part or all of the flow rate parameters, thickness parameters and discontinuity parameters of the urine column.

[0038] The controller evaluates the urine health of the person based on the morphological data, thereby obtaining urine health information. After obtaining the urine health information, the controller outputs it to the above-mentioned information output module, and the information output module outputs the urine health information to the user, so that the user can conveniently obtain his own urine health information, and can make a judgment on his physical health based on the information and determine whether to make further examinations.

[0039] Embodiment 2 This embodiment provides a flushing control method, which is applied to the urinal provided in the previous embodiment, and more specifically, to the controller in the urinal. Figure 5a The distance of objects in the solid line area is shown in the figure, while objects in the dotted line area cannot be detected when water accumulates. Figure 5b As shown, after microwaves are emitted, they are reflected back by water in large quantities and cannot penetrate the water. Microwaves continue to detect water. When there are people or no people in the detection range, the detection distance data of the microwave sensing component will change accordingly as the water level rises.

[0040] like Figure 6 As shown, the flushing control method provided in this embodiment includes the following steps: S21. Obtain a first distance between the urinal and the target object.

[0041] The first distance here refers to the distance between the microwave sensing component and the target object. The target here is generally a human body or urine. The first distance refers to the shortest distance between the microwave sensing component and the target object or the distance between the microwave sensing component and the nearest point of the target object.

[0042] S22. Control the flushing component according to the first distance.

[0043] During implementation, the first distance is first judged, and the judgment here refers to comparing the first distance with a preset blocking distance threshold value A. The preset blocking distance threshold value A is set to be no greater than the distance between the front end of the urinal body and the microwave sensing component, and greater than the distance between the microwave sensing component and the accumulated water in the urinal when the urinal is blocked.

[0044] When the first distance is smaller than the preset blocking distance threshold value A, it is determined that the urinal is blocked, and at this time the flushing assembly is controlled not to flush, so as to avoid sewage overflow.

[0045] Through the above control, it is possible to accurately determine whether blockage occurs 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 instructions when flushing is not in progress, so as to avoid sewage overflow.

[0046] In a specific implementation of this embodiment, the following steps are also included: Figure 7 As shown: S23, controlling the flushing component to perform pre-flushing.

[0047] By re-judging the first distance, when the first distance is greater than the preset blocking distance threshold value A and less than the first distance threshold value T_in, as Figure 8 As shown, the flushing assembly is controlled to pre-flush, or pre-wet the surface of the urinal. Through the above operation, the surface of the urinal can be pre-wetted to prevent urine from directly contacting the surface, and to facilitate flushing of urine after subsequent flushing.

[0048] In another specific implementation of this embodiment, the following steps are also included: Fig. 9 shown.

[0049] S24, controlling the flushing component to flush again.

[0050] When the first distance is greater than the second distance threshold value T_out, the flushing component is controlled to flush again. This situation generally corresponds to the actual scenario that the user leaves after urinating. At this time, the flushing component is controlled to flush again to clean the surface of the urinal. By flushing again, the purpose of cleaning the urinal can be achieved, so that the urinal is kept clean and hygienic, and dirt is prevented from forming on the surface of the urinal.
