[0036] See also Figure 1 , Figure 1 The structure explosion diagram of the embodiment 1 of the urinal testing device provided by the present invention is shown. Figure 2 for Figure 1 The structural cross-sectional view of the urinal test device in FIG. Figure 1 and Figure 2 As shown, in Example 1, the urinal testing device mainly includes a mobile base, a water outlet assembly and a control module.

[0037] The mobile base includes a housing 14, a base 16, a base body 17, a first drive motor 11, a second drive motor 12, a drive wheel 13 and a steering wheel 131. The base body 17 is equipped with the first drive motor 11, the second drive motor 12, the drive wheel 13 and the steering wheel 131. The first drive motor 11 is used to drive the steering wheel 131 to turn, the second drive motor 12 is used to drive the drive wheel 13 to rotate, the drive wheel 13 drives the mobile base as a whole to move forward or backward, and the steering wheel 131 is used to control the forward direction of the mobile base. The two cooperate to drive the mobile base to move to any position.

[0038] The base 16 is sleeved on the base body 17 to cover the base body 17 .

[0039] The shell 14 is fixedly connected to the base 16 by means of snap-on or screw-on connection. The shell 14 is located above the base 16 and is hollow inside. A water level observation window 141 is provided on the shell for observing the water level of the water outlet assembly. A display screen 142 is also provided on the shell, and the display screen 142 is communicated with the control module to display information. A speaker 31 and a microphone 32 are also installed on the shell 14, and both the speaker 31 and the microphone 32 are communicated with the control module. The speaker 31 is used to provide feedback to the user, and the microphone 32 is used to collect the user's voice for processing by the control module.

[0040] A fixing arm 15 is provided on the top of the housing 14 , extending upward and having a hollow passage inside.

[0041] The water outlet assembly includes a water tank 21, a water pump 22, a water pipe 23 and a movable arm, and the movable arm includes a first arm 24 and a second arm 25. The water tank 21 is arranged in the internal cavity of the housing 14, and its bottom is fixedly connected to the top of the seat body 17 of the mobile base by screw connection or other means, and is used to store water; a water pump 22 is arranged in the water tank 21, and one end of the water pump 22 is connected to the outside of the water tank 21 through a pipeline, and the pipeline is connected to the water pipe 23. The water pump 22 is connected to the communication module for communication, and is controlled by the communication module to pump the water in the water tank 21 to the water pipe 23 through the pipeline. The water pipe 23 passes through the hollow channel of the fixed arm 15, and then passes through the inside of the movable arm to form a water outlet.

[0042] One end of the movable arm is rotatably connected to the mobile base in the vertical direction. In the present embodiment, one end of the first arm 24 in the movable arm is rotatably connected to the end of the fixed arm 15 provided on the outer shell 14 on the mobile base, so that the first arm 24 can be rotated in the vertical direction; a hollow pipe is provided inside the first arm 24, and the water pipe 23 can be inserted into the hollow pipe of the first arm 24 after passing through the hollow pipe of the fixed arm 15.

[0043] The second arm 25 is constructed as a nozzle structure, one end of which is rotatably connected to the end of the first arm 24, and has a hollow pipe with two ends opened inside. When the water pipe 23 extends from the end position of the first arm 24, it is connected to one end of the hollow pipe of the second arm 25, and the water flow can directly flow into the hollow pipe of the second arm 25. Therefore, the other end of the hollow pipe of the second arm 25 is configured as the water outlet end of the water pipe 23, and the water flow is sprayed out from here.

[0044] In this embodiment, the rotation of the first arm 24 and the second arm 25 can be performed manually.

[0045] The control module is specifically an electric control board with a processor thereon. The electric control board has a pre-set program therein, which can be used to control the mobile base to move to a predetermined position facing the urinal and control the water pump 22 to spray water from the end of the second arm 25 .

[0046] A navigation component 10 is provided on the seat body 17, which may be an infrared structured light component, which is communicatively connected with the control module, cruises through infrared structured light, and feeds back corresponding blocking signals to the control module so that the control module can drive the mobile base to move to a predetermined position.

[0047] The control module includes a voice processing unit and a wireless communication unit. The voice processing unit can receive external voice commands, such as "start" and other commands, so as to control the test device to start working. Specifically, the sound can be collected through a microphone arranged on the housing 14. The wireless communication unit can be connected to the mobile smart terminal for communication, and the mobile smart terminal can be used to control the test device to work, such as controlling the movement of the mobile base.

[0048] In addition, the present invention also provides Example 2, which has the following differences compared to Example 1:

[0049] In this embodiment, the water outlet assembly further includes two rotating motors, one of which is installed at a position where the first arm 24 is rotatably connected to the fixed arm 15, and the other is installed at a position where the second arm 25 is rotatably connected to the first arm 24; the output ends of the two rotating motors are fixedly connected to the rotating shaft of the rotating connection structure, and the first arm 24 can be respectively controlled to rotate relative to the fixed arm 15 and the second arm 25 can be respectively controlled to rotate relative to the first arm 24 through the rotation of the output ends of the rotating motors. Both rotating motors are communicatively connected to the control module and operate under the control of the control module.

[0050] A rangefinder and a servo motor are also installed on the mobile base. The rangefinder can be an infrared rangefinder or a laser rangefinder, which is installed in the center of the mobile base so that it is directly opposite to the urinal. The rangefinder is connected to the control module for communication and can transmit distance information to the control module. When the mobile base moves to a predetermined position directly opposite to the urinal, the control module controls the rangefinder to start distance measurement. The output end of the servo motor is fixedly connected to the rangefinder. By rotating the output end of the servo motor, the rangefinder can be driven to swing in the vertical direction, so that the rangefinder can measure the distance of the blocking object in the vertical direction.

[0051] Since the urinal bowl is usually shaped to protrude toward the user, it has a bowl front end, above which is the bowl, and below which is the urinal body. The water outlet assembly needs to be positioned on the bowl so that water can flow into the bowl.

[0052] When the mobile base moves to a predetermined position facing the urinal, the rangefinder starts to measure the distance between it and the urinal in front at different elevation angles by swinging. Since the front end of the bowl is closest to the front, the distance to the rangefinder is also the shortest. After obtaining this shortest distance, the control module can determine the position of the front end of the bowl of the urinal relative to the rangefinder in conjunction with the rotation angle fed back by the servo motor, thereby controlling the rotation motor on the movable arm to rotate so that the water outlet end of the water pipe 23 points to the bowl of the urinal.

[0053] The present invention also provides a control method for a urinal test device, which is used to control the urinal test device of the above-mentioned embodiment 2, and mainly comprises the following steps:

[0054] Receiving a first instruction, driving the movable base to move to the predetermined position facing the urinal;

[0055] Receiving the second instruction, starting the rangefinder and driving the servo motor to rotate, and obtaining in real time a first distance between the rangefinder and the urinal measured on a set vertical plane and a rotation angle of the servo motor;

[0056] The position of the front end of the urinal bowl is determined according to the first distance and the rotation angle, and the rotary motor is driven to rotate to adjust the swing angle of the support arm so that the water outlet end of the water pipe points to the urinal bowl.

[0057] Specifically, after receiving the first instruction, the control module drives the mobile base to move to a predetermined position facing the urinal. The first instruction here can be a voice instruction. After waking up the test device in the form of voice, the test device can communicate with the mobile smart terminal through the wireless communication module. The mobile smart terminal transmits a travel signal to the control module, starts the navigation component, and makes the mobile base move by itself; of course, the movement of the mobile base can also be directly controlled by the mobile smart terminal.

[0058] After the mobile base moves to a predetermined position facing the urinal, the control module receives a second instruction, which may be a voice instruction, and starts the simulated urination step in the form of voice. In this step, the control module first starts the rangefinder and the servo motor, and the rangefinder starts to measure the distance between the blocking object in front of its position and itself, while the servo motor rotates to drive the rangefinder to swing, and the distance is measured within a vertical range. This distance is the first distance, which can be fed back to the control module through the rangefinder, and the rotation angle of the servo motor can also be fed back to the control module, and there is a corresponding relationship between the two.

[0059] According to the above-mentioned first distance and the value of the rotation angle, the position of the front end of the urinal bowl can be determined, and the process is as follows: the first distance is measured at a manually set interval, and within the manually set error range, a first distance value that is simultaneously smaller than the two measured values ​​before and after is used as a reference value for determining the front end of the urinal bowl, and the position of the front end of the urinal bowl relative to the distance meter is determined in conjunction with the rotation angle of the servo motor corresponding to the reference value. Specifically, the distance meter performs a distance measurement operation at a manually set interval, and the first distance fed back is a discontinuous numerical point, each numerical point corresponds to a rotation angle of the servo motor. When there is a first distance value whose size satisfies the condition that it is simultaneously smaller than the first distance values ​​measured before and after twice, it can be determined that the measured position corresponding to the first distance value is the front end of the urinal bowl. Since the position of the distance meter set on the mobile base is known, the position of the front end of the urinal bowl relative to the distance meter can be determined in conjunction with the rotation angle of the servo motor.

[0060] At the same time, since the end position of the fixed arm on the mobile base is known relative to the position of the rangefinder, the swing angle of the first arm 24 and the second arm 25 can be adjusted by driving the rotary motor to rotate, so that the control module can control the end position of the second arm 25 to point to the bucket slot of the urinal.

[0061] The urinal testing device and the corresponding control method provided by the present invention can simulate the process of a user approaching a urinal and using the urinal, and can give viewers an intuitive feeling, making it easier for viewers to understand the functional characteristics of the urinal product. At the same time, the position of the water outlet of the testing device can be automatically adjusted so that the water outlet can be guaranteed to be above the urinal bowl when discharging water, avoiding spraying outside the bowl.

[0062] The description of the above specification and embodiments is used to explain the protection scope of the present invention, but does not constitute a limitation on the protection scope of the present invention. Through the enlightenment of the present invention or the above embodiments, ordinary technicians in this field can obtain modifications, equivalent substitutions or other improvements to the embodiments of the present invention or part of the technical features thereof through logical analysis, reasoning or limited experiments, which should be included in the protection scope of the present invention.
