[0036] When the sensitivity of the automatic induction function of the thermostatic shower faucet needs to be tested, first, align the water inlet port of the thermostatic faucet body 2 to be tested with the upper port of the water inlet pipe 4, and combine the threaded sleeve 5 with the water inlet pipe 4 and the threaded connection of the water inlet port of the thermostatic faucet body 2, adjust the threaded sleeve 5 to rotate upward, so that the water inlet port of the thermostatic faucet body 2 is threadedly connected with the threaded sleeve 5, and the installation of the thermostatic faucet body 2 to be tested is completed;

[0037] Secondly, start the servo motor 28 through the controller 29, the servo motor 28 drives the reciprocating screw rod 12 to rotate, under the threaded cooperation of the movable block 13 and the reciprocating screw rod 12, and the sliding cooperation of the movable block 13 and the guide rod 27, the movable block 13 is stably moved to the left side, under the action of the connecting rod 14, the induction plate 15 is synchronously moved, and under the action of the fixed rod 16, the first rack 18 and the second rack 19 are synchronously moved to the left side, when the induction plate 15 passes through the lower side of the thermostatic faucet body 2, the thermostatic faucet body 2 is inducted by the induction plate 15, starts to discharge water, and discharges water into the transparent measuring cup 11 below, under the action of the pressure sensor 10, the weight of the water entering the transparent measuring cup 11 is detected, the purpose of recording the water discharge amount of the thermostatic faucet body 2 in the first test is achieved, and the recorded data is transmitted to the controller 29;

[0038] With the continuous movement of the movable block 13 to the left side, the second rack 19 is in contact with the gear 17, under the meshing action of the second rack 19 and the gear 17, and the rotary connection of the support shaft 8 and the mounting frame 3, the support shaft 8 is driven to rotate, and the support plate 9 is synchronously rotated, achieving the purpose of driving the transparent measuring cup 11 to overturn to the left side, and the water in the transparent measuring cup 11 is poured out and falls into the water tank 7 below through the through slot 6 for collection, achieving the recycling of water resources;

[0039] In this process, when the gear 17 rotates, under the meshing action of the gear 17 and the reset rack 22, and the sliding cooperation of the reset rack 22 and the cross rod 21, the reset rack 22 is moved to the right side, compressing the spring 23 on the right side, and stretching the spring 23 on the left side;

[0040] The movable block 13 continues to move until the movable block 13 moves to the leftmost side of the reciprocating screw rod 12, and under the action of the reciprocating screw rod 12, the movable block 13 starts to move to the right side, thereby driving the first rack 18 and the second rack 19 to move to the right side synchronously. With the movable block 13 moving to the right side, the second rack 19 is driven to move to the right side of the gear 17 and is disengaged from the gear 17.
