As shown in fig. 10, the switching control valve 14 includes an arc-shaped stem 26, a control valve plunger 27, a first spring 28, a guide rod 29, a fixed disk 30, a first tapered surface 31, wherein, a fixed disc 30 with a plurality of water leakage round holes is fixedly arranged at one end of the installation groove 22 close to the water storage cavity 60, two ends of the control valve plunger 27 are symmetrically provided with two first conical surfaces 31, the control valve plunger 27 is slidably arranged in a control valve chute 21 arranged at the lower end of the mop pool 3, the two first conical surfaces 31 on the control valve plunger 27 are respectively matched with the two ends of the corresponding control valve chute 21, one end of the control valve plunger 27 is fixedly provided with three guide rods 29 which are uniformly distributed in the circumferential direction, one end of each guide rod 29 far away from the control valve plunger 27 is slidably arranged on the fixed disc 30, and a first spring 28 is arranged between one end of the control valve plunger 27 provided with the guide rods 29 and the fixed disc 30; the other end of the control valve plunger 27 is fixedly provided with an arc-shaped ejector rod 26, and one end of the arc-shaped ejector rod 26 far away from the control valve plunger 27 passes through the corresponding arc-shaped groove 25 to be matched with a second arc-shaped conical surface 42 on the water-saving valve plunger 32.

The utility model discloses when initial condition, the one end contact that is close to water storage chamber 60 of control valve plunger 27 and control valve spout 21 is sealed under water conservation valve plunger 32 to the effect of arc ejector pin 26. The utility model relates to a wash port 23 drainage direction is along the tangent direction of the disc in the 3 drain pipe 38 in mop pond because make the water that flows out through wash port 23 along the tangent direction of the disc in the 3 drain pipe 38 in mop pond, have around the effect that the disc sprayed outside the water saving valve plunger 32, improve the cleaning performance to water saving valve plunger 32.

The upper end of the triggering bulge 39 designed by the utility model is higher than the supporting bar 12 when the water-saving valve 11 is closed, so that the mop can trigger the plunger 32 of the water-saving valve smoothly.

The specific working process is as follows: when using the utility model discloses a water saving fixtures, before opening hot and cold water switch 4 and emit hot water, at first open control switch 6 for the rivers that stop flowing in the hot water pipe of being connected between hot and cold water switch 4 hot water access mouth and the hot water source flow into in mop pond 3 through control switch 6 and mop pond outlet pipe 9 and store and be used for wasing the mop.

After the mop is cleaned, the lower end of the mop presses the trigger bulge 39 downwards, the trigger bulge 39 drives the water-saving valve plunger 32 to move downwards through the connecting column 40, so that the second arc-shaped conical surface 42 on the water-saving valve plunger 32 is separated from the first arc-shaped conical surface 41 on the water outlet of the mop pool 3, and sewage is discharged from a gap between the two arc-shaped conical surfaces.

When the plunger 32 of the water-saving valve moves downwards, on one hand, the plunger 32 of the water-saving valve can drive the connecting rod 50 to move downwards, and the connecting rod 50 moves downwards to drive the telescopic inner rod 51 to move downwards, so that the clamping block 54 arranged at the lower end of the telescopic outer sleeve 52 is contacted with the first inclined surface 58 on the limiting block 55, and the limiting block 55 limits the telescopic outer sleeve 52; therefore, the telescopic inner rod 51 moves downwards to extrude the third spring 53, so that the first spring 28 is compressed, the third spring 53 is compressed to transmit the downward pressure to the telescopic outer sleeve 52, and the telescopic outer sleeve 52 extrudes the limiting block 55 through the clamping block 54; when the third spring 53 is pressed to a certain degree, the limiting block 55 gradually moves towards the inner side of the limiting shell 56 under the action of the first inclined surface 58, and when the limiting block 55 is completely separated from the clamping block 54, the limiting block 55 loses the limiting effect on the telescopic outer sleeve 52, at the moment, the telescopic outer sleeve 52 can quickly press the damping inner rod 46 under the action of the pressed third spring 53, so that the damping inner rod 46 moves downwards relative to the damping shell 49, meanwhile, the second spring 48 is pressed, the previously compressed third spring 53 is released, and a user judges that the squeezing process is finished and lifts the mop through the release of the felt force of the mop and the sound of the clamping block 54 breaking through the limiting block 55 in the releasing process; when the limiting block 55 is separated from the downward moving fixture block 54, the fixture block 54 moves downward, and the limiting block 55 stretches out again under the action of the limiting spring 57. It can be known from last analysis that the setting of fixture block 54 and stopper 55 can make the user know the degree of pushing down in order to guarantee the degree that the damping rod is compressed, and then guarantees that the recovery time of damping rod is enough long to guarantee that sewage is all drained.

On the other hand, when the plunger 32 of the water saving valve is pushed down, the plunger 27 of the control valve moves to the side of the water discharge hole 23 along the slide slot 21 of the control valve under the restoring force of the first spring 28, the plunger 27 of the control valve does not contact with the two ends of the slide slot 21 of the control valve during the movement, and the water shell in the water storage cavity 60 flows out through the slide slot 21 of the control valve, the water discharge groove 24 and the water discharge hole 23; after the water-saving valve plunger 32 continues to move downwards, the control valve plunger 27 contacts and seals one end of the control valve chute 21 close to the water discharge hole 23 under the action of the restoring force of the first spring 28, and water in the water storage cavity 60 does not continuously flow out; because the control valve plunger 27 moves downwards fast, the water flowing out of the water storage cavity 60 in the downward movement process is seldom ignored; then the control valve plunger 27 continues to move downwards to separate the arc-shaped mandril 26 from the second arc-shaped conical surface 42 of the control valve plunger 27, and the control valve plunger 27 is always in contact with and sealed with one end of the control valve slide groove 21 close to the water discharge hole 23. When the mop cloth is lifted, the speed of upward movement of the telescopic rod 16 is lower due to the action of the damper 18, namely, the telescopic rod 16 can slowly move upward; in the process of moving up the telescopic rod 16, after the fixture block 54 on the telescopic outer sleeve 52 is contacted with the second inclined surface 59 on the limit block 55 which extends out again, the limit block 55 moves inward again under the action of the second spring 48 until the fixture block 54 moves to the upper side of the limit block 55, and the limit block 55 extends out again under the action of the limit spring 57; and the telescopic rod 16 moves upwards to drive the water saving valve plunger 32 to move upwards through the connecting rod 50.

In the upward moving process, on one hand, the second arc-shaped conical surface 42 on the plunger 32 of the water-saving valve is contacted with the first arc-shaped conical surface 41 at the lower end of the water outlet of the mop pool 3 to close the water outlet of the mop pool 3, so that when the water-saving valve 11 is in a closed state, the water outlet of the mop pool 3 is in a closed state, and the water flowing into the mop pool 3 can be stored.

On the other hand, the upward moving speed of the control valve plunger 27 due to the action of the damper 18 is slow, the time that the control valve plunger 27 is positioned in the middle of the control valve sliding groove 21 is prolonged, so that the water outflow amount in the water storage cavity 60 is large, impurities stuck on the water-saving valve plunger 32 can be cleaned, and in the cleaning process, the water-saving valve plunger 32 moves upward while rotating under the matching of the thread groove 44 on the thread rod 43 and the spiral slider 45 on the trigger sleeve 35, and the cleaning effect is improved.
