when the water pressure is normal, the left piston 46 is displaced downwards under the action of the left piston spring 48, so that the left piston push rod 47 is displaced downwards to be meshed with the first ratchet wheel 54 and drive the first ratchet wheel 54 to rotate, the first ratchet wheel 54 rotates to drive the winding wheel 72 coaxial with the first ratchet wheel to rotate to tighten the second pull rope 30, and the lifting block 22 is reset upwards;

when the water pressure in the fluid through hole 12 is reduced, the abutting block 49 is contacted with water, the water pressure in the fluid through hole 12 is reduced, so that the water pressure in the piston cavity 45 on the right side is reduced, the piston 46 on the right side is displaced downwards under the action of the piston spring 48 on the right side to abut against the abutting block 49, the motor 67 is started, the motor 67 drives the transmission shaft 66 to rotate, so that the second bevel gear 65 rotates to drive the first bevel gear 70 engaged with the second bevel gear to rotate, the first bevel gear 70 rotates to drive the rotating vane 15 coaxial with the first bevel gear 70 to rotate, and the water flow in the fluid through hole 12 is accelerated to enter the user pipeline through the communication through hole 19 and the water outlet pipeline interface 20 to complete pressurization in the user pipeline;

when the water supply is stopped, the electromagnet 44 is started to enable the fixture block 41 to contract into the fixture block sliding groove 40, the lifting block 22 is enabled to move downwards to the lower limit position, water flows into the liquid storage cavity 29 through the lifting block opening 23, the corrugated hose 32 and the through hole 78 for storage, when the water supply is stopped, the piston 46 on the right side moves downwards to abut against the abutting block 49, the abutting block 49 does not contact with the water, when the water supply is restarted in the fluid through hole 12, the abutting block 49 contacts with the water and is communicated with a circuit of the electromagnetic spring 60, the water pressure pushes the piston 46 on the right side to move upwards, so that the piston push rod 47 on the right side moves upwards to be meshed with the first ratchet wheel 54 and the second ratchet wheel 50 and drive the first ratchet wheel 54 and the second ratchet wheel 50 to rotate, the first ratchet wheel 54 rotates to enable the lifting block 22 to reset upwards, the second ratchet wheel 50 rotates to drive the coil 75 coaxial with the second, so that the battery 61 pushes the electromagnetic spring 60 to be electrified, the spline housing 59 is enabled to move forwards under the action of the electromagnetic spring 60 to be meshed with the first transmission gear 58 until the battery 61 runs out of electric quantity, the electromagnetic spring 60 drives the spline housing 59 to reset, when a large amount of water is used by a user in a short time after water comes, namely the user opens the faucet to forget to close after water stops, at the moment, water flow drives the rotating blade 15 to rotate through the fluid through hole 12, so as to drive the first bevel gear 70 coaxial with the rotating blade 15 to rotate, the first bevel gear 70 rotates to drive the second bevel gear 65 meshed therewith to rotate, so as to drive the first belt wheel 69 coaxial with the second bevel gear 65 to rotate, the first belt wheel 69 rotates to drive the second belt wheel 57 to rotate, the second belt wheel 57 rotates to drive the spline housing 59 coaxial therewith to rotate, so as to drive the first transmission gear 58 meshed therewith to rotate, the first transmission gear 58 rotates to drive the second transmission gear 64 meshed therewith to rotate, thereby driving the block valve 18 coaxial with the second transmission gear 64 to rotate and block the fluid through hole 12, closing the main valve and avoiding the waste of water;

when the main valve needs to be opened, the rotary disc 62 is rotated to drive the blocking valve 18 coaxial with the rotary disc to rotate, so that the communication through hole 19 is communicated with the fluid through hole 12.
