[0035] In this embodiment, the switch driving mechanism 2 further includes a limiting part. When the flip cover 31 of the flip - type water drainer 3 is pushed by the second driving part to contact the limiting part, the flip cover 31 of the flip - type water drainer 3 is in the closed position, and the flip cover 31 can be pushed open by the first driving part. The limiting part is specifically located at the eccentric position of the flip cover 31 and abuts against the upper surface or the lower surface of the flip cover 31 when the flip cover 31 is closed. The limiting part specifically includes two limiting rods 23 arranged in parallel. The two limiting rods 23 are located at the eccentric position of the flip cover 31 of the flip - type water drainer and abut against the upper surface of the flip cover 31 when the flip cover 31 is closed. When the first driving part extends, it pushes the flip cover 31 on the side of the two limiting rods 23 away from the flip cover center, and when the second driving part extends, it passes through the interval between the two limiting rods 23 and pushes the flip cover 31 on the side of the two limiting rods 23 close to the flip cover 31 center.

[0036] In this embodiment, the first driving part and the second driving part are both rod-shaped.

The middle part spans above the first water storage tank 1 and installs the first air cylinder 21 and the second air cylinder 22. Specifically, the first air cylinder 21 and the second air cylinder 22 are respectively connected to the fixed rod 41 by a connecting piece 24. The connecting piece 24 is L-shaped. One side of it fixes the first air cylinder 21 or the second air cylinder 22, and the other side is connected to the long installation hole 411 arranged along the length direction of the fixed rod 41 by a long strip hole 241 and a bolt assembly, so that the connecting piece 24 can be adjusted left and right and up and down relative to the fixed rod 41. The two limiting rods 23 are vertical and are fixed to the same component as the second air cylinder 22 (i.e., the upper ends of the two limiting rods 23 are respectively fixed to one side of the connecting piece 24 where the second air cylinder 22 is located). The lower ends of the two limiting rods 23 are respectively located on the eccentric side of the flip cover 31. The first air cylinder 21 is in a vertical state, and its piston rod 211 faces downward and is located on the side of the limiting part (i.e., the two limiting rods 23) away from the center of the flip cover drainer 3 in the extended state, as Figure 7 shown. The second air cylinder 22 is in an inclined state, and its piston rod 221 extends obliquely downward when it extends, and passes through the space between the two limiting rods 23 and pushes the flip cover 31 downward on the side of the limiting part (i.e., the two limiting rods 23) close to the center of the flip cover drainer 3, so as to close the flip cover 31.

[0038] In this embodiment, the present invention further includes a rotation driving mechanism 5, which is connected to the first water storage tank 1 or the flip-down water outlet device 3 installed at the drain outlet to drive the first water storage tank 1 and / or the flip-down water outlet device 3 to rotate a preset angle around the axis of the flip-down water outlet device 3. Specifically, the rotation driving mechanism 5 includes a motor 51 and a turntable 52. The first water storage tank 1 is fixed on the turntable 52, and the turntable 52 is driven by the motor 51 to drive the first water storage tank 1 and the flip-down water outlet device 3 thereon to rotate a preset angle around the axis of the flip-down water outlet device 3.

[0039] In this embodiment, as Figures 2-4 shown, the rotation driving mechanism 5 further includes a rotating shaft 53 and a support 54. The support 54 is located below the turntable 52. The rotating shaft 53 is rotatably arranged on the support 54 around the axis of the flip-down water outlet device 3, and the upper end of the rotating shaft 53 is fixedly connected to the turntable 52, and the lower end of the rotating shaft 53 is in transmission connection with the motor 51. Specifically, the support 54 is fixed below the turntable 52 by a bracket 55. The motor 51 is installed on the bracket 55. The bracket 55 is received in the frame 4. The output shaft of the motor 51 faces upward and is coaxially fixed to the rotating shaft 53. A bearing 56 is arranged between the rotating shaft 53 and the support 54 to make the rotating shaft 53 rotate smoothly relative to the support 54.

[0040] In this embodiment, the present invention further includes a circulation mechanism 6, which sends the water discharged from the first water storage tank 1 back to the first water storage tank 1. As Figure 2 shown, the circulation mechanism 6 includes a circulation pump 62 and a second water storage tank 61. The second water storage tank 61 is communicated with the drain outlet of the first water storage tank 1, and the water output from the second water storage tank 61 is sent back to the first water storage tank 1 through the circulation pump 62 or the circulation pump 62 and the connected pipeline. Both the circulation pump 62 and the second water storage tank 61 are received in the frame 4.

[0041] In this embodiment, the first water storage tank 1 is specifically a glass box, and the second water storage tank 61 is a water tank, but it is not limited thereto. An overflow pipe 11 is arranged in the first water storage tank 1, and the drainage end of the overflow pipe 11 is communicated with the second water storage tank 61.

[0042] In this embodiment, the present invention further includes a PLC controller (not shown in the figure), which controls the working states of the switch driving mechanism 2 and the rotation driving mechanism 5. The PLC controller has a human-machine interface 7, which is convenient for the staff to set working parameters, such as the water on / off time, rotation angle of the flip-down water outlet device 3, the number of tests of the flip-down water outlet device 3 switch (one opening and one closing of the flip 31 is one time), etc. The human-machine interface 7 is arranged on the front side of the top of the frame 4.

[0043] A flip - type drainer life - testing device of the present invention, during operation, first install the flip - type drainer 3 to be tested at the drain outlet of the first water storage tank 1, and keep the flip 31 of the flip - type drainer 3 in a closed state, as Figure 5 shown. Then, set the above - mentioned parameters on the human - machine interface 7 of the PLC controller, and pour an appropriate amount of water into the first water storage tank 1 (the excess water overflows from the overflow pipe 11 into the second water storage tank 61). Then, the PLC controller controls the coordinated actions of the first cylinder 21, the second cylinder 22, and the motor 51. Specifically: The first cylinder 21 starts, and its piston rod 21 extends to open the flip 31, as Figure 6 shown, so that the water in the first water storage tank 1 gradually drains into the second water storage tank 61 through the flip - type drainer 3; after the piston rod 211 of the first cylinder 21 opens the flip 31 and retracts, when the preset water - passing time arrives, the second cylinder 22 starts, and its piston rod 221 extends to close the flip 31, as Figure 7 shown. After the piston rod 221 of the second cylinder 22 closes the flip 31 and retracts, the motor 51 starts, driving the first water storage tank 1 and the flip - type drainer 3 to rotate by an angle (such as 3 - 15° etc.) around the central axis of the flip - type drainer 3, and then repeat the above - mentioned opening and closing processes of the flip 31 until the preset number of tests is reached. During the test, the water drained into the second water storage tank 61 is recycled back to the first water storage tank 1 through the circulation pump 62, so that the test water is recycled, thus achieving the purpose of water conservation. During the test, it is also possible not to pour water into the first water storage tank 1, but directly conduct the opening and closing tests of the flip 31 to achieve the dry friction test of the flip 31 (the above - mentioned process is the wet friction test of the flip 31). After the test is completed, remove the flip - type drainer 3, observe the appearance wear of the flip 31 of the flip - type drainer 3, and then conduct a sealing test in accordance with the sealing performance test in Clause 6.7.1 of JC / T932 - 2013 "Drainage Fittings for Sanitary Ware".

[0044] A flip - type drainer life - testing method of the present invention installs the flip - type drainer to be tested at the installation port provided by a preset installation body, and uses a switch driving mechanism to control the flip of the flip - type drainer to automatically open and close, and repeats the execution until the preset number of times is reached.

[0045] In this embodiment, a rotation driving mechanism is set to drive the installation body and / or the flip - type drainer to rotate by a preset angle around the axis of the flip - type drainer at a preset time. Specifically, after the switch driving mechanism controls the flip - type drainer to execute one opening and closing operation, the rotation driving mechanism immediately drives the installation body and / or the flip - type drainer to rotate by a preset angle around the axis of the flip - type drainer, and repeats this cycle until the preset number of times is reached.

[0046] In this embodiment, the installation body is the first water storage tank, and the installation port is the drain port of the first water storage tank; a circulation mechanism is provided to send the water discharged from the first water storage tank back to the first water storage tank.

[0047] In this embodiment, the switch driving mechanism has a first driving part and a second driving part that can automatically expand and contract, and the expansion and contraction states of the first driving part and the second driving part are opposite. When the first driving part extends, it drives the flap of the flap drain installed at the installation port (i.e., the drain port of the first water storage tank) to open, and when the second driving part extends, it drives the flap of the flap drain installed at the installation port (i.e., the drain port of the first water storage tank) to close.

[0048] In this embodiment, the switch driving mechanism further includes a limiting part. When the flap of the flap drain is pushed by the second driving part to contact the limiting part, the flap of the flap drain is in the closed position, and the flap can be pushed open by the first driving part. The limiting part is located at the eccentric position of the flap and abuts against the upper surface or the lower surface of the flap when the flap is closed. The first driving part is located on the side of the limiting part away from the center of the flap in the extended state, and when the second driving part extends, its tail extends to the side of the limiting part close to the center of the flap.

[0049] In this embodiment, the switch driving mechanism includes a first cylinder and a second cylinder. The first driving part is the piston rod of the first cylinder, and the second driving part is the piston rod of the second cylinder; the first driving part and the second driving part extend into the first water storage tank respectively in the extended state.

[0050] A method for testing the service life of a flap drain of the present invention can be implemented by using the above-mentioned device for testing the service life of a flap drain of the present invention. Its specific working process is as described above and will not be elaborated here.

[0051] A device and method for testing the service life of a flap drain of the present invention can perform a service life test by controlling the automatic opening and closing of the flap drain, thereby accurately obtaining the service life information of the flap drain and filling the gap that there is no device for testing the service life of a flap drain on the current market. The setting of the limiting part can ensure that the flap is accurately closed and avoid the situation that the flap is not closed in place. The present invention further includes the rotation driving mechanism, which can simulate the state where the opening and closing position of the flap of the flap drain is not fixed and can be closed at any position of 360°, making the service life test of the flap drain more tend to the actual use state, thereby helping to obtain more accurate service life information of the flap drain.
