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) at this time.Inlet valve 47 is closed, the water inside piston cylinder 41 pushed to
Upper flowing, since the draining being made of communicating passage 53 and water flow buffer chamber 51 is bypassed to very small (the i.e. flow of the resistance of flow
Easily flowed in draining bypasses), and water outlet 44 bypasses the resistance to flow to resistance much size drainings of flow,
Water inside piston cylinder 41 is discharged by the path for pushing selection resistance small, i.e., is discharged in being bypassed from draining, at this time at piston mechanism
In draining stroke in vain (outlet valve 46 is closed).And in piston mechanism drains stroke in vain, since draining bypasses
It is very small to the resistance of flow, therefore motor 10 drives balance weight mechanism 70 persistently to accelerate, the energy that motor 10 exports is converted into
The kinetic energy of rotor, gear set 20, transmission mechanism 30 and balance weight mechanism 70, at the same upper mobile board 54 can by water jet propulsion to
Lower movement.Electric water pump continues accumulation of energy, closes baffle 57 until upper mobile board 54 moves downwardly to contact lid, makes the water on baffle 57
Recirculation hole 571 is closed, and the flow in making draining bypass is difficult to through throughbore 571, and draining bypass at this time is closed (such as Fig. 5
It is shown), after draining bypass is closed, the water outlet 44 of piston mechanism becomes the remaining unique draining of the water inside piston cylinder 41
Path, therefore the water inside piston cylinder 41 can be squeezed through the discharge of water outlet 44, 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, inside piston cylinder 41
Water can only be squeezed through water outlet 44 be discharged (being equivalent to bringing to a halt for flow at this time), electric water pump savings energy can be quick-fried
Hair, by water piston body 42 energetically extrusion piston cylinder 41 inside, outlet valve 46 is opened at this time, and piston mechanism realization is from water outlet
Mouth 44 exports the flow of one section of high pressure rapidly.After the energy burst of electric water pump savings, rotor, gear set 20, transmission
The rotating speed of mechanism 30 and balance weight mechanism 70 can reduce (because energy releases), inside 42 continuous extrusion piston cylinder 41 of piston body
Water makes piston mechanism holding persistently export low pressure water flow, and piston mechanism holding persistently exports low pressure water flow, until piston body 42 is transported
It moves to top (as shown in Figure 6), the entire draining stroke of piston mechanism (i.e. added with effect draining go in vain by draining stroke at this time
Journey) terminate, water base inside piston cylinder 41 is discharged.After water discharge inside piston cylinder 41, outlet valve 46 is re-closing off, electricity
10 continue working of machine drives piston body 42 to move downward by gear set 20 and transmission mechanism 30, and piston mechanism, which is in, at this time inhales
Water stroke (as shown in Figure 7), inlet valve 47 are opened, and water is flowed by water inlet in piston cylinder 41 from external water source, while by
The draining bypass that water flow buffer chamber 51 forms loses resistance, under the rebound effect of spring 52, again pushes up lower movable plate 55
, lower movable plate 55 makes upper mobile board 54 be in discrete state again with baffle 57 by connecting rod 56, i.e., draining bypass, which is in, leads
Logical state returns to the original state of electric water pump until piston body 42 moves to the bottommost of piston cylinder 41, complete a work
Make the period.In 10 continue working of motor, it is recycled into next work period.It should be noted that the elastic force power of spring 52
Less than the draining power of outlet valve 46.
In practical applications, electric water pump structure disclosed in this invention can be applied in different products, such as Fig. 8
It is shown, for using water gun structure made from electric water pump disclosed in this invention, which includes shell 100, in shell
Electric water pumps of the present invention are fixedly mounted in 100 inside, and water inlet line 200 accesses inside shell 100, and with piston mechanism

The present invention cleverly by changing the structure of piston mechanism, adds draining bypass and control mechanism, makes piston machine
There is effectively draining stroke and invalid draining stroke in structure, and in draining stroke in vain, make electric water pump in drainage procedure
Energy can be put aside, draining bypass is closed using control mechanism, so that piston mechanism is entered effectively draining stroke, electric water pump is made to accumulate
The ability of storage is broken out, and realizes the flow of one section of high pressure of electric water pump export rapidly.No need to increase the power of motor 10 by the present invention, i.e.,
The flow output of high pressure rapidly can be obtained, this electric water pump structure of the invention, delicate structure is small, light weight, cost
It is low, it is easy to carry, it is worthy of popularization.
In practical application, by adjusting the structure of draining bypass is changed, such as increases draining bypass and connect with piston cylinder 41
The aperture at place, the internal diameter of water stream channel for increasing draining bypass, the bend of reduction draining bypass and the angle etc. for adjusting bend,
Draining bypass may be implemented, water outlet 44 is far smaller than to the discharge flow of piston cylinder 41 to the resistance of the discharge flow of piston cylinder 41
Resistance makes electric water pump in draining stroke in vain, can put aside energy to greatest extent.In addition, passing through adjusting water outlet valve 46
Elasticity, the pore size of water outlet 44, can also 44 pairs of piston cylinders 41 of adjusting water outlet mouth the resistance of flow is discharged.
In practical application, by changing structure or the control of control mechanism, the effective row for changing electric water pump may be implemented
Water stroke realizes the accumulation of energy time for changing electric water pump, the final output water flow pressure size for realizing adjustment electric water pump
Effect.Specifically, can realize by changing the geomery of water flow buffer chamber 51 or changing the length of connecting rod 56 and change electricity
Effective draining stroke of dynamic water pump, that is, change the accumulation of energy time of electric water pump.
In practical application, according to actual job needs, it can be combined into the best electric water pump scheme of effect, herein no longer
It is superfluous to chat.
