The working principle is as follows:

before use, the spur gear A7 is simultaneously engaged with the spur rack A8 and the spur rack B9, and rods on the side surfaces of the spur rack A8 and the spur rack B9 are already inserted into holes on the grooves of the square baffle A2;

when the pull rod 4 is used, a person holds the pull rod 4, firstly, the pull rod 4 is rotated, and then the cylindrical gear A7 on the shaft of the pull rod 4 is driven to rotate, so that the cylindrical gear A7 drives the spur rack A8 and the spur rack B9 to slide, and then rods on the side surfaces of the spur rack A8 and the spur rack B9 are separated from holes in the groove of the square baffle A2, and the pull rod 4 can be automatically pulled;

then, a person pulls the pull rod 4 backwards to enable the pull rod 4 to drive the cylindrical gear A7 to move, so that the cylindrical gear A7 is separated from the spur rack A8 and the spur rack B9, the pull rod 4 drives the cylindrical gear A7 to be meshed with the spur rack C10 and the spur rack D11, the pull rod 4 is pulled downwards to drive the sleeve rod 5, the front end of the sleeve rod 5 moves, the pull rod 4 slides in the groove of the square baffle A2, when the pull rod 4 slides to the bottom of the groove, the person rotates the pull rod 4 to enable the pull rod 4 to drive the cylindrical gear A7 to rotate, the spur rack C10 and the spur rack D11 are driven to slide, and therefore rods on the side surfaces of the spur rack C10 and the spur rack D11 penetrate through holes in the sleeve rod 5 to be matched with holes in the groove of the square baffle A2, and therefore the pull rod 4 cannot move due to mistaken collision, and power is not disconnected;

when the pull rod 4 drives the sleeve rod 5 to move, the sleeve rod 5 drives the trapezoidal groove 13 to move, the trapezoidal groove 13 pushes the rectangular strip block 15 to move, the rectangular strip block 15 drives the sliding rod 16 to move, and when the sliding rod 16 moves, the electrifying pipe A18 is driven to move; meanwhile, the sliding rod 16 drives the spur rack E19 to move, further drives the cylindrical gear B20 to rotate, so as to drive the cylindrical gear C21 to rotate, further drives the lead screw of the movable lead screw mechanism 22 to rotate, further drives the sliding to move, and further drives the sliding block to drive the electrifying pipe B23 to move;

when the electrifying pipe A18 moves downwards, the electrifying pipe B23 moves rightwards at the same time, and when the electrifying pipe A18 is in contact with the electrifying pipe B23, electrification is started;

when the water is detected by the sensor 14 when the water is not electrified, the red light on the square baffle A2 is turned on to remind people of paying attention, and meanwhile, the signal is transmitted to the square fixing plate 31 to enable the motor on the square fixing plate 31 to start working to drive the cylindrical gear D24 to rotate;

the cylindrical gear D24 is driven to rotate through the motor, the special-shaped rack 25 is driven to move, the fixed block 26 is driven to move, the swing rod 28 is driven to rotate in the moving process of the fixed block 26, and the swing rod 28 is rotationally connected with the sliding block A27, so that when the swing rod 28 rotates, the sliding block A27 can slide on the fixed block 26 according to the principle of the Pythagorean theorem;

the swinging rod 28 rotates around a middle shaft, so that the connecting rod A29 is driven to swing, and the connecting rod B30 is driven to swing, so that the connecting rod B30 drives the sliding block B32 to slide in the sliding groove of the square fixing plate 31;

when the sliding block B32 moves, the rubber sleeve A33 is driven to move, so that the rubber sleeve A33 is sleeved on the electrifying pipe A18, and a power supply is insulated;

when the sliding block B32 moves, the sliding block B32 can drive the spur rack F34 to move, and after the spur rack F34 is meshed with the cylindrical gear E35, the spur rack F34 moves to drive the cylindrical gear E35 to rotate, so that the spur rack G36 is driven to slide, and the rubber sleeve B37 is driven to move, so that the rubber sleeve B37 is sleeved on the electrifying pipe B23, water vapor is prevented from entering, and danger is avoided;

after the internal moisture is dried, the inductor 14 drives the motor to rotate reversely, so that the internal equipment is reset, and the next use is facilitated.
