[0034] The present invention will be further described below through specific embodiments.

[0035] The terms "first" and "second" used in this invention are merely for ease of description and to distinguish different components with the same name, and do not indicate a sequential or primary / secondary relationship.

[0036] In the description of this invention, the orientations or positional relationships indicated by terms such as "up," "down," "left," "right," "front," and "back" are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this invention. They are not intended to indicate or imply that the device referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this invention.

[0037] See Figures 1 to 8 A toilet seat flushing test system includes a conveying device 10 and at least one fixture plate 20. The conveying device 10 can utilize a conventional toilet seat production conveyor line. The fixture plate 20 is located on the conveying device 10 and is used to hold toilet seats 30; one fixture plate 20 can hold one toilet seat 30. The conveying device 10 can move the fixture plate 20 through a first station 11 and a second station 12. The first station 11 can be used for powering on or calibrating the toilet seat 30. The second station 12 can be used for flushing testing of the toilet seat 30; that is, the conveying device 10 can move the fixture plate 20 to the first station 11 for power-on initialization and calibration, and then move the fixture plate 20 to the second station 12 for flushing testing. Setting up two stations can greatly improve testing efficiency.

[0038] The testing system of the present invention also includes a power supply sliding contact 21 and a signal sliding contact 22 on the tooling plate 20. The power supply sliding contact 21 is used to realize the electrical connection between the toilet seat 30 and the power supply device 40, and the signal sliding contact 22 is used to connect the flush valve of the toilet seat 30 to transmit the detected vibration signal.

[0039] Furthermore, it also includes a power supply sliding contact line 16, a signal sliding contact line 17, at least one triggering device 50, and a control device 70. The power supply sliding contact line 16 is located at the first station 11 and the second station 12; that is, the power supply sliding contact line 16 can be located at the first station 11 and extend along the conveying direction a of the conveying device 10 to the second station 12. The power supply sliding contact line 16 is connected to the power supply device 40, which can be the power supply for the toilet seat 30 production conveyor line or a separate backup power supply. The power supply sliding contact line 16 can be located on one side of the conveying device 10, and multiple copper wires can be installed on the side facing the tooling plate 20. The power supply sliding contact line 16 can slide into contact with the power supply sliding contact 21 to achieve electrical connection, ensuring continuous power supply to both stations throughout the process of the toilet seat 30 flowing to the first station 11 and the second station 12. The signal sliding contact line 17 is installed at the second station 12, which can be located on the other side of the conveying device 10. When the tooling plate 20 flows to the second station 12, the signal sliding contact 22 on it can slide and make electrical contact with the signal sliding contact line 17. The signal sliding contact 22 is also connected to the control device 70, which can transmit the detected vibration signal to the control device 70.

[0040] Specifically, to facilitate the connection between the toilet seat 30 and the power supply sliding contact 21, the tooling plate 20 is also equipped with a power supply socket (not shown in the figure). The power supply socket is connected to the power supply sliding contact 21, and the power plug of the toilet seat 30 can be inserted into the power supply socket to draw power. The signal sliding contact 22 is also connected to a vibration detection element (not shown in the figure). This vibration detection element can be connected to the water inlet of the flush valve on the toilet seat 30 to detect vibration signals. That is, when the flush valve is flushing, it will generate vibration. Therefore, by detecting the vibration signal of the flush valve, it is possible to determine whether the flushing function is normal. This vibration detection element can be a vibration sensor or a piezoelectric passive buzzer, preferably a piezoelectric passive buzzer, such as a 1407 type piezoelectric passive buzzer.

[0041] In this invention, at least one triggering device 50 can be installed on the second station 12. The remote control used for testing can be placed on the triggering device 50, and the triggering device 50 can also trigger the remote control to send a flushing command. The control device 70 can be connected to the triggering device 50 to control its operation. In practical applications, depending on the type of remote control used for testing, two triggering devices 50 can be installed on the second station 12 to accommodate the needs of different remote controls.

[0042] Furthermore, a trigger device 50 is also provided on the first workstation 11. The remote control used for pairing can be placed on the trigger device 50. The trigger device 50 can also trigger the remote control to send a pairing command, so that the remote control and the toilet seat 30 are paired for subsequent testing. Figure 1 The triggering device 50 is not shown in the first station 11.

[0043] Specifically, the triggering device 50 includes a bracket 51, a pressing head 52, and a first driving device 53. The bracket 51 has a base 55 for holding the remote control. The base 55 may have a positioning groove on which the remote control is placed. Depending on the type of remote control, the positioning groove can be circular or square. For example, two triggering devices 50 can be installed on the second station 12: one triggering device 50 is suitable for a circular remote control 80, and the other triggering device 50 is suitable for a square remote control 80.

[0044] The pressing head 52 is located above or to the side of the remote control. The first driving device 53 is connected to the pressing head 52 and can drive it to move and press the remote control. Specifically, the pressing head 52 is located in different positions depending on the type of remote control. For example, for a round remote control 80, the pressing head 52 can be located above the remote control, and the remote control can be pressed from top to bottom; for a square remote control 80, if its buttons are located on the side of the remote control, the pressing head 52 can be located on the side of the remote control, and the remote control can be pressed from the side, depending on the specific type of remote control 60. The first driving device 53 is a cylinder, and the telescopic rod of the cylinder is connected to the pressing head 52. The complete cylinder structure is not shown in the figure. A connecting plate 54 is correspondingly provided on the bracket 51. The connecting plate 54 can be located above or on the side of the base 55, and the telescopic rod passes through the connecting plate 54.

[0045] Furthermore, the triggering device 50 of the present invention can also have its base 55 configured as a power supply base. A battery compartment is housed within the power supply base, and a first conductive element and a second conductive element are disposed within a positioning slot. The first and second conductive elements are connected. After the remote control's battery cover is opened, it is placed into the positioning slot, allowing the first and second conductive elements to respectively contact and connect with the positive and negative terminals inside the remote control. Using this power supply base avoids the need for frequent battery removal and installation from the remote control.

[0046] The tooling plate 20 of the present invention may include an upper plate 23 and a lower plate 24 connected together. The upper plate 23 is used to place a toilet seat 30, and the lower plate 24 is placed on the conveying device 10 and has a notch near its center. It also includes a second driving device, a control switch 60, and a blocking member 61. The second driving device and the blocking member 61 can be located at the second station 12 and disposed below the tooling plate 20. The second driving device drives the blocking member 61 to rise or fall. The control switch 60 is mounted on the conveying device 10 and connected to the second driving device to control its operation, causing the blocking member 61 to rise and insert into the notch or fall out of the notch. The second driving device may be a cylinder (only the rod is shown in the figure, and the complete cylinder structure is not shown). The blocking member 61 may be rod-shaped or block-shaped, depending on the actual situation. When the blocking member 61 rises and inserts into the notch, the tooling plate 20 stops flowing and remains at the first station 11 to facilitate relevant test operations; when the blocking member 61 falls out of the notch, the tooling plate 20 continues to flow to the next station. As needed, a second drive device, a control switch 60, and a blocking member 61 may also be provided on the first station 11 to drive the tooling plate 20 to remain in the first station 11.

[0047] Furthermore, it also includes a first position sensor 13 and a second position sensor 14. The first position sensor 13 is disposed on the first station 11 and is used to detect whether the tooling plate 20 is in position at the first station 11; the second position sensor 14 is disposed on the second station 12 and is used to detect whether the tooling plate 20 is in position at the second station 12. The first position sensor 13 and the second position sensor 14 can be limit switches. The control device 70 is connected to the first position sensor 13 and the second position sensor 14 to receive position information. In practical applications, it may also include a photoelectric sensor 15 to detect whether there is a toilet seat 30 on the tooling plate 20. The number of photoelectric sensors 15 can be one or more, and they can be arranged at appropriate positions on the first station 11 and the second station 12. The control device 70 is connected to the photoelectric sensor 15 to receive sensing information.

[0048] In the system of this invention, the control device 70 adopts a PLC controller, which can be used to control the working state of the first drive device 53, receive and amplify vibration information, and output relevant parameters, such as the magnitude of the vibration current signal. Therefore, a display device 71 can also be provided, which is connected to the control device 70 to display the magnitude of the vibration current signal. The test result can be determined by the magnitude of the vibration signal.

[0049] This invention also proposes a toilet seat flushing test method, implemented using the aforementioned toilet seat flushing test system, comprising: when the toilet seat 30 moves to the first station 11, controlling the power supply device 40 to power on and initialize the toilet seat 30, and continuously supplying power until the toilet seat 30 moves to the second station 12; when the toilet seat 30 is in the second station 12, controlling the trigger device 50 to activate the remote control 80 to send a flushing command, and the control device 40 receiving vibration signals from the vibration detection element to determine the test result. The method of this invention may further include a code pairing operation at the first station.

[0050] The specific working principle is as follows:

[0051] When testing is conducted using the circular remote control 80 provided with the toilet seat 30, the testing process includes the following:

[0052] Power-on initialization and pairing: Place the circular remote control 80 on the base 55 of the trigger device 50 beforehand, insert the power plug of the toilet seat 30 into the power socket on the tooling plate 20, and install the vibration detection element at the inlet of the flush valve of the toilet seat 30. When the tooling plate 20 is conveyed to the first station 11 by the conveying device 10, the power supply sliding contact 21 and the power supply sliding contact line 16 slide into contact, and the toilet seat 30 is powered on and initialized. When the tooling plate 20 is in place, the control device 70 controls the first drive device 53 to drive the pressing head 52 to press the circular remote control 80 for a preset time length, and the toilet seat 30 and the circular remote control 80 are successfully paired.

[0053] Flushing Test: The circular remote control 80 is removed and placed on the base 55 of the trigger device 50 on the second station 12. The tooling plate 20 continues to move towards the second station 12, and the power supply device 40 continues to supply power. After reaching the position, the control device 70 controls the first drive device 53 to drive the pressing head 52 to press the circular remote control 80. The circular remote control 80 sends a flushing command. After receiving the flushing command, the toilet seat 30 starts the flushing valve. The flushing valve generates vibration. The vibration detection element detects the vibration signal and transmits it to the control device 70 through the signal sliding contact 22 and the signal sliding contact line 17. The control device 70 amplifies the signal to obtain the vibration current signal, which is displayed on the display device 71. The magnitude of the displayed vibration current signal can be used to determine whether the test is passed or not. Alternatively, the vibration current signal can be compared with a preset range value. If it is within the set range value, the test is passed; otherwise, the test is failed.

[0054] When using a dedicated test remote control, no pairing is required. The test process is as follows:

[0055] Power-on initialization: Insert the power plug of the toilet seat 30 into the power socket on the fixture plate 20, install the vibration detection element at the water inlet of the flush valve of the toilet seat 30, and when the fixture plate 20 is conveyed to the first station 11 by the conveying device 10, the power supply sliding contact 21 and the power supply sliding contact line 16 slide into contact, and the toilet seat 30 is powered on and initialized.

[0056] Flushing Test: The tooling plate 20 continues to move to the second station 12. The power supply device 40 continues to supply power. After reaching the station, the control device 70 controls the first drive device 53 to drive the pressing head 52 to press the test remote control. The test remote control sends a flushing command. After receiving the flushing command, the toilet seat 30 starts the flushing valve. The flushing valve generates vibration. The vibration detection element detects the vibration signal and transmits it to the control device 70 through the signal sliding contact 22 and the signal sliding contact line 17. The control device 70 amplifies the signal to obtain the vibration current signal, which is displayed on the display device 71. The test can be judged by the magnitude of the displayed vibration current signal. Alternatively, the vibration current signal can be compared with a preset range value. If it is within the set range value, the test passes; otherwise, the test fails.

[0057] In this invention, in addition to judging the flushing test results by the magnitude of the vibration current signal, the power value of the toilet seat 30 when the flushing function is activated can also be used for judgment. The relevant current and voltage can be obtained through the power supply sliding contact line 16, the power supply sliding contact 21 and the power plug. For example, when the toilet seat 30 is in the activated state without the flushing function, the power of the whole machine is 2.5W. After flushing, the power value increases by 1W to 3.5W. Each time it is greater than 1W, which proves that the flushing valve is working normally and the water circuit is open normally.

[0058] The above are merely specific embodiments of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention using this concept shall be considered as infringing upon the protection scope of the present invention.
