In this embodiment, the water tank further comprises a base 90 for fixing to a mounting hole (not shown) provided in the bottom wall of the water tank, and a drain port 91 is provided in the base 90, and the bottom of the cylinder 61 is detachably and fixedly connected to the base 90.
The working process of the invention is briefly described as follows:
as shown in fig. 6, when there is no water or insufficient water in the water tank, when the water tank needs to be filled with water, only the water supply switch of the water supply source is turned on to enable the water to flow into the water passage 83 in the water passing body 80, at this time, since there is no water in the water tank or insufficient water in the float tank 42 of the float assembly 40, the float 41 is in a falling state, the float 41 drives the water inlet lifting rod 43 to open the water inlet pressure relief hole 26, the water inlet rubber pad 24 moves away from the water inlet water passage 211 under the action of the water pressure, thereby opening the water inlet water passage 211, the water flow can flow into the water inlet valve cavity 22 and out of the water outlet of the water inlet opening and closing valve 20 and into the first water outlet pipe 81, and the water in the first water outlet pipe 81 flows into the first guide pipe 611 and flows into the water tank from the bottom end opening of the first guide pipe 611 to supply water to the water tank.
As shown in fig. 7, when the water in the water tank continuously rises and enters the floating tank 42, the floating barrel 41 floats under the action of the water in the floating tank 42, the floating barrel 41 drives the water inlet lifting rod 43 to close the water inlet pressure relief hole 26, at this time, the water in the water inlet back pressure cavity 25 cannot be discharged from the water inlet pressure relief hole 26, and the water inlet rubber pad 24 moves towards the direction close to the water inlet water passing hole 211 under the action of the water pressure, so that the water inlet water passing hole 211 is closed, and water stop is realized.
As shown in fig. 8, when water in the water tank needs to be discharged, only the switch member is operated, so that the electromagnet 51 is electrified to generate magnetism, the iron sheet 52 is attracted, the iron sheet 52 and the electromagnet 51 are attracted to drive the water discharge lifting rod 53 to rotate, the water discharge lifting rod 53 opens the water discharge hole 311, the water discharge rubber pad 34 moves away from the water discharge water through hole 311 under the action of water pressure, so as to open the water discharge water through hole 311, water flow can flow into the water discharge valve cavity 32 and flow out of the water outlet of the water discharge opening and closing valve 30 and flow into the second water outlet pipeline 82, water in the second water outlet pipeline 82 flows into the second conduit 612 and flows into the hydraulic cavity 63 through the water outlet 64, and the water flowing into the hydraulic cavity 63 drives the piston 62 to move upwards, so that the sealing assembly 70 is driven to move upwards to open the water discharge outlet 91. When the water discharge is finished, the switch piece or the switch piece is automatically closed, the electromagnet 51 is not electrified and the magnetism disappears, under the action of the reset elastic piece 54, the water discharge lifting rod 53 reversely rotates to separate the iron sheet 52 from the electromagnet 51, the water discharge lifting rod 53 closes the water discharge pressure relief hole 311 again, water in the water discharge back pressure cavity 35 cannot be discharged, the water discharge rubber cushion 34 moves towards the direction close to the water discharge water passing hole 311 under the action of water pressure, and therefore the water discharge water passing hole 311 is closed, and water stop is achieved. At this time, the water is returned to the water inlet state as shown in fig. 6, and the water inlet and discharge operation of the water tank is reciprocally performed.
As shown in fig. 9, when the working water level of the water tank needs to be increased, that is, when the height of the water inlet and outlet integrated control valve needs to be adjusted to a higher position, firstly, the locking piece between the outer shell 12 and the inner shell 13 is unlocked to enable the outer shell 12 or the upper cover 11 to slide relatively, then only one hand is needed to push and pull the outer shell 12 or the upper cover 11 upwards, so that the outer shell 12 or the upper cover 11 can drive the water passing body 80 and the float assembly 40 to move upwards together, the water level is adjusted, the outer shell 12 and the inner shell 13 are locked again through the locking piece after the water level is adjusted, the position is prevented from running, the water level adjusting function is reliable,
