fig. 21 and 22 show a state where the movable ratchet wheel 43 is located at the first position, and fig. 23 and 24 show a state where the movable ratchet wheel 43 is located at the second position. When the movable ratchet wheel 43 is located at the second position, the initial state is set, in this state, the flow adjusting handle 511 is pressed, the flow adjusting handle 511 pushes the ratchet rod 42 through the key 41, the pressing surface 422 of the ratchet rod 42 presses the inner inclined surface 434 of the movable ratchet wheel 43, and the movable ratchet wheel 43 moves downwards and rotates for a certain angle; the flow adjusting handle 511 is released, the movable ratchet wheel 43 moves upwards under the action of the return force of the abutting spring until the outer inclined surface 435 abuts against the hanging surface 1228 on the inner wall of the temperature adjusting rod 122, the movable ratchet wheel 43 rotates for a certain angle under the guidance of the hanging surface 1228 again, and continues to move upwards until the movable ratchet wheel stops at the tooth bottom 1227, at this time, the movable ratchet wheel 43 is at the first lower position as shown in fig. 21 and 22, the flow adjusting handle 511 abuts against the bottom of the accommodating groove 61 of the temperature adjusting handle 6, and the outer surface of the cylinder bottom of the flow adjusting handle 511 is flush with the opening end of the accommodating groove 61 of the temperature adjusting handle 6. The flow adjusting handle 511 is pressed again, the flow adjusting handle 511 pushes the ratchet rod 42 again through the button 41, the pressing surface 422 of the ratchet rod 42 presses against the inner inclined surface 434 of the movable ratchet 43, the movable ratchet 43 moves downwards again and rotates for a certain angle, at this time, the flow adjusting handle 511 is released, the movable ratchet 43 moves upwards under the action of the restoring force of the pressing spring until the outer inclined surface 435 abuts against the guide surface 1229 in the temperature adjusting rod 122, the movable ratchet 43 rotates for a certain angle again until the second bump 433 enters the rotation stopping groove 1226 and continues to rise and finally stops against the rotation stopping groove 1226, at this time, the movable ratchet 43 returns to the higher second position shown in fig. 23 and 24, the flow adjusting handle 511 disengages from abutting against the temperature adjusting handle 6 and moves upwards to the highest point of the movement stroke thereof, the temperature adjusting handle 6 moves upwards under the action of the restoring spring 7 until the accommodating groove 61 abuts against the first elastic buckle, at this time, the flow-adjusting knob 511 is exposed from the open end of the accommodating groove 61 of the temperature-adjusting knob 6, and the two are not completely overlapped in the axial direction, so that they can be independently operated without interfering with each other.
Referring to fig. 21 and 22, when the movable ratchet wheel 43 is in the first position as shown in fig. 21 and 22, the lower end of the connecting shaft 5111 of the flow adjusting handle 511 pushes the valve rod 3 to stop at the lowest point in the movement stroke of the valve rod 3, the boss 33 of the valve rod 3 pushes the diaphragm 21 and seals the pressure relief hole 210, and the diaphragm 21 reliably pushes against the top end of the water passing wall 1124 under the action of the pushing spring 22 and the valve rod 3. At this time, since the water through hole 212 communicates the water pressure chamber 100 and the water inlet chamber 200, the water pressure in the water pressure chamber 100 is equal to the water pressure in the water inlet chamber 200, for the diaphragm 21, the pressure applied to one side of the diaphragm 21 in the water pressure chamber 100 is equal to the water pressure in the water pressure chamber 100 multiplied by the surface area of the diaphragm 21, and the pressure applied to the lower surface of the diaphragm 21 is equal to the water pressure in the water inlet chamber 200 multiplied by the surface area of the part of the diaphragm in the water inlet chamber 200, so the pressure applied to the upper surface of the diaphragm 21 is greater than the pressure applied to the lower surface of the diaphragm, the diaphragm 21 reliably supports against the top end surface of the water wall, the water in the water inlet chamber 200 cannot flow into the water outlet chamber 300, and the water outlet 112c does not discharge water. When the movable ratchet wheel 43 moves from the first position shown in fig. 21 and 22 to the second position shown in fig. 23 and 24, the abutting surface 5123 in the flow regulating rod 512 lifts the valve rod 3 upwards to the highest point in the movement stroke of the valve rod 3, the boss 33 of the valve rod 3 is separated from the diaphragm 21 and opens the pressure relief hole 210, at this time, because the water pressure chamber 100 loses pressure and the water pressure in the water inlet chamber 200 still exists, the diaphragm 21 moves upwards against the acting force of the abutting spring 22, the diaphragm 21 is separated from the abutting end surface of the water passing wall 1124, the water inlet chamber 200 is communicated with the water outlet chamber 300, and the water outlet 112c discharges water.
Referring to fig. 23 to 26, when the flow rate needs to be adjusted, the flow adjusting handle 511 is rotated to drive the flow adjusting rod 512 to rotate, the flow adjusting rod 512 drives the flow adjusting member 52 to rotate relatively through the valve rod 3, when the water passing opening 522 on the flow adjusting member 52 completely corresponds to the water outlet 112c, the water outlet amount of water from the water outlet 112c is the largest, when the flow adjusting member 52 rotates to partially shield the water outlet 112c by the side wall thereof, and simultaneously, when the water passing opening 522 partially corresponds to the water outlet 112c, the water outlet amount of the water outlet 112c is relatively smaller, and when the flow adjusting member 52 rotates to completely stagger the water passing opening 522 from the water outlet 112c, the water outlet 112c is completely shielded by the flow adjusting member 52, and the water outlet amount is not or extremely small.
