In order to more clearly illustrate the present embodiment electric water pump principle, below in conjunction with attached drawing, to the present embodiment work
Thin description is carried out as process：
The original state of electric water pump, piston cylinder 41 are in maximum receiving water, will under the elastic force effect of spring 52
Lower movable plate 55 jacks up, and to which lower movable plate 55 makes upper mobile board 54 be in discrete state with baffle 57 by connecting rod 56, that is, arranges
Water bypass is in the conduction state, when motor 10 works, pushes piston body 42 to transport upwards by gear set 20 and transmission mechanism 30
Dynamic, piston mechanism is in draining stroke (as shown in figure 4, arrow indicates the direction of motion of flow in figure) at this time.Inlet valve 47 closes
It closes, the water inside piston cylinder 41, which is pushed, to be flowed up, due to by the draining that is made of communicating passage 53 and water flow buffer chamber 51
Road is very small to the resistance of flow (i.e. flow easily flows in draining bypasses), and water outlet 44 is remote to the resistance of flow
Long-range small draining bypasses the resistance to flow, and the water inside piston cylinder 41 is discharged by the path for pushing selection resistance small, i.e., from row
It is discharged in water bypass, piston mechanism is in invalid draining stroke at this time (outlet valve 46 is closed).And in piston mechanism
In vain in draining stroke, since draining bypass is very small to the resistance of flow, motor 10 drives balance weight mechanism 70 persistently to add
Speed, the energy that motor 10 exports are converted into the kinetic energy of rotor, gear set 20, transmission mechanism 30 and balance weight mechanism 70,
Upper mobile board 54 can be moved down by water jet propulsion simultaneously.Electric water pump continues accumulation of energy, until upper mobile board 54 moves downwardly to
Contact lid closes baffle 57, and the throughbore 571 on baffle 57 is made to be closed, and the flow in making draining bypass is difficult to pass through throughbore
571, draining bypass at this time is closed (as shown in Figure 5), and after draining bypass is closed, the water outlet 44 of piston mechanism becomes work
Water inside plug cylinder 41 is left unique drainage path, therefore the water inside piston cylinder 41 can be squeezed through 44 row of water outlet
Go out, i.e., piston mechanism enters effectively draining stroke.Since in draining stroke in vain, electric water pump has put aside certain energy,
When draining bypass is closed, the water inside piston cylinder 41 can only be squeezed through the discharge of water outlet 44 and (be equivalent to flow at this time
Bring to a halt), electric water pump savings energy can break out, by the water inside piston body 42 energetically extrusion piston cylinder 41, at this time

After energy burst, rotor, gear set 20, transmission mechanism 30 and balance weight mechanism 70 rotating speed can reduce (because energy discharges
), the water inside 42 continuous extrusion piston cylinder 41 of piston body makes piston mechanism holding persistently export low pressure water flow, piston mechanism
Holding persistently exports low pressure water flow, until piston body 42 moves to top (as shown in Figure 6), the entire row of piston mechanism at this time
Water stroke (i.e. draining stroke drains stroke added with effect in vain) terminates, and water base inside piston cylinder 41 is discharged.Piston cylinder 41
After internal water discharge, outlet valve 46 is re-closing off, 10 continue working of motor, is driven and is lived by gear set 20 and transmission mechanism 30
Cock body 42 moves downward, and piston mechanism is in water suction stroke (as shown in fig. 7, arrow indicates the movement side of flow in figure at this time
To), inlet valve 47 is opened, and water flows by water inlet in piston cylinder 41 from external water source, while by 51 groups of water flow buffer chamber
At draining bypass lose resistance, under the rebound effect of spring 52, lower movable plate 55 is jacked up again, lower movable plate 55 is logical
Crossing connecting rod 56 makes upper mobile board 54 be in discrete state again with baffle 57, i.e. draining bypass is in the conduction state, until piston
Body 42 moves to the bottommost of piston cylinder 41, that is, returns to the original state of electric water pump, completes a work period.In motor 10
In continue working, it is recycled into next work period.It should be noted that the elastic force power of spring 52 is less than outlet valve 46
Drain power.

As shown in Figure 10, in the present embodiment, using a side opening 58 is opened on the side wall of piston cylinder 41, connected by side opening 58
Lead to a simple drainage channel, reduce movable component, is mainly realized and drained by the opening and closing of 42 contralateral exposure 58 of piston body
The opening and closing in channel.During motor 10 works, piston body 42 is pushed to move upwards by gear set 20 and transmission mechanism 30, at this time piston
Mechanism is in draining stroke, and since the draining of drainage channel composition is bypassed to small flow resistance, (i.e. flow is easily draining
Flowed in bypass), and water outlet 44 is far longer than resistance of the drainage channel to flow to the resistance of flow, inside piston cylinder 41
Water, which is pushed, selects unresisted path to be discharged, i.e., is discharged from drainage channel, and piston mechanism is in invalid draining stroke at this time
(outlet valve 46 is closed).And in piston mechanism drains stroke in vain, since drainage channel is to small flow resistance, because
This motor 10 drives balance weight mechanism 70 persistently to accelerate, and the energy that motor 10 exports is converted into rotor, gear set 20, transmission
The kinetic energy of mechanism 30 and balance weight mechanism 70, electric water pump continue accumulation of energy, until piston body 42 moves up to contact lid and closes side
Hole 58, makes drainage channel be closed, and after drainage channel is closed, the water outlet 44 of piston mechanism becomes the water inside piston cylinder 41
Be left unique drainage path, therefore water piston cylinder 41 inside can be squeezed through water outlet 44 be discharged, i.e., piston mechanism into
Enter effectively draining stroke.Since in draining stroke in vain, electric water pump has put aside certain energy, when drainage channel is closed
