Second high-pressure chamber 48 is arranged in the other end opposite with the first high-pressure chamber 47, the second high-pressure chamber 48 and first
High-pressure chamber 47 is about 46 central symmetry of the pump housing.It is similar, the second high-pressure chamber 48 include a water inlet a ' (not shown) and
The water inlet list between water inlet branch 432 and high pressure chest c ' is arranged in one water outlet b ' (not shown) and a high pressure chest c '
To valve a1 ', it is arranged and goes out water one-way valve b1 ' between water outlet branch 442 and high pressure chest c '.Water feeding one-way valve a1 and water inlet are unidirectional
Valve a1 ' constitutes the first unidirectional valve group, goes out water one-way valve b1 and go out water one-way valve b1 ' to constitute the second unidirectional valve group.Second high pressure chest
Room 48 is identical as 47 structure of the first high-pressure chamber, and corresponding component function is also similar, and concrete structure and operation principle please join
The description of the first high-pressure chamber 47 is examined, this specification is no longer described in detail the second high-pressure chamber 48.
In the present embodiment, plunger 45 is for controlling water feeding one-way valve a1 (a1 ') and going out the opening of water one-way valve b1 (b1 ')
And closing.Fig. 8 and Fig. 9 are please referred to, when plunger 45 is moved to the direction of high pressure chest c (c '), the space of high pressure chest c (c ') is squeezed
When pressing, and making to form high pressure in high pressure chest c (c '), water feeding one-way valve a1 (a1 ') is closed, and goes out water one-way valve b1 (b1 ') openings, high
Chamber c (c ') is pressed to be pumped to water outlet branch 441.And it is moved to the direction far from high pressure chest c (c ') when plunger 45, high pressure chest c (c ')
Space be released, to form negative pressure, water feeding one-way valve a1 (a1 ') is opened, and goes out water one-way valve b1 (b1 ') closings, water from
Water inlet branch 431 flows to high pressure chest c (c ').
Specifically, an end of plunger 45 is deep into high pressure chest c, another end is extend into high pressure chest c ',
It is reciprocating in c and c ' in high pressure chest in two ends of plunger 5 under the transmission of transmission mechanism 30.High pressure chest c and high pressure
Chamber c ' is alternately squeezed so that plunger 45 is in reciprocatory movement, and total there are one high pressure chests to be in the state being extruded, therefore
What pump 40 can continue has water to pump out, and compared to the pump of single high pressure chest, water pumping efficiency improves 1 times.More specifically, plunger 45 is in high pressure
Reciprocating motion in chamber c and c ', driving check valve is opened accordingly or partition, when the movement of plunger makes high pressure chest c (c ') formation
When high pressure, check valve b1 (b1 ') will be opened, water flows out to water outlet from high pressure chest, when the movement of plunger keeps high pressure chest c (c ') empty
Between when being released to form negative pressure, negative pressure drives check valve a1 (a1 ') to open, and water is flowed into from water inlet in high pressure chest.
The setting of high pressure chest needs volume and volumetric efficiency in view of pump.If high pressure chest is excessive, the body of pump is not only resulted in
Product becomes larger, and causes cavity too many greatly very much, and the volumetric efficiency of high pressure chest becomes smaller, water absorbing capacity force difference, corresponding efficiency volume ratio drop
It is low, therefore the size of high pressure chest setting just holds the positions of two limit in piston reciprocation motion process and is preferred.Define plunger
Distance between two extreme positions is the stroke of plunger, in the present embodiment, the diameter of the aperture ratio plunger of high pressure chest c or c '
Big 0.5mm-2mm, high pressure chest c or c ' are bigger 0.5mm-2mm than the stroke of plunger in the length of the piston reciprocation direction of motion.This implementation
In example, the length of diameter big 1mm, high pressure chest c or c ' in the piston reciprocation direction of motion of the aperture ratio plunger 45 of high pressure chest c or c '
It is bigger 1mm than the stroke of plunger.
Preferably, plunger 45 is made of metal material, and two ends of plunger 45 are hollow, filled out using the smaller material of density
It fills, the quality of plunger can be mitigated in this way, to mitigate the vibration problem of the complete machine in reciprocatory movement of plunger 45, while
The power for promoting plunger is reduced, energy expenditure is reduced.In the present embodiment, packing material is plastics, also may be used in other embodiment
To use resin or light-weight metal, such as aluminium.
The stroke and diameter of pump and the reciprocal time of reciprocating motion determine the flow of pump.In order to which the ginseng of pump is described in detail
Relationship between number, for the present embodiment, definition diameter of plunger is D (unit mm), and the stroke of plunger is S (unit mm), plunger
The reciprocating frequence of movement is N (rpm), and the flow of pump is B (unit L/min).So, B=D × S × N × k, k represent coefficient (often
Number).Therefore, when the reciprocating frequency of plunger is constant (when the invariablenes turning speed of driving motor), in order to realize scheduled discharge
Flow B (L/min) needs to increase diameter D but reduces stroke S, or reduces diameter D but increase stroke S.
But the diameter of plunger causes more greatly the width of pump 40 to become larger, the stroke of plunger causes to pump 40 lengths more greatly,
Under the premise of meeting preset flow B, diameter D and stroke S that plunger how is arranged determine the volume of pump 40, directly affect
The portability of jetting machine.Moreover, as the diameter increases, the area of the release of plunger 45 increases, required thrust also phase
It should increase, in order to increase thrust, electro-motor just needs the power (higher volume of motor) of bigger, also, receives reaction
The pump housing of power must be reinforced.In this way, the width of jetting machine becomes larger, and unfavorable increases cost.It is another
Aspect, when stroke S increases, the amount of exercise of plunger 45 increases, the reciprocating motion for causing pump 40 to increase in the longitudinal direction, and pumping
In the case that frequency is constant, stroke S increases, and the movement velocity of plunger is also increased, needs using with more high-wearing feature
Material, which results in the increases of cost.
In the present embodiment, in order to which the pressure for making jetting machine spray changes in a certain range, the rotating speed of motor is set
It is adjustable, that is to say, that the frequency N of the reciprocating motion of pump changes in a certain range.Specifically, as the frequency N moved back and forth
When increase, pushed amount reduces, and the diameter of plunger needs to reduce, if not increasing plungers length, the size of plunger accordingly reduces, pump
Flow B reduces.On the other hand, when the frequency N of reciprocating motion reduces, pushed amount increases, unfavorable to the size of plunger 45
Increase, since frequency reduces, the flow of pump accordingly reduces, and too low frequency is concussion Producing reason, therefore too small
Reciprocating frequency is inappropriate.On the other hand, for the certain pump of parameter, delivery flow is not with reciprocating motion
The increase of frequency N and increase, but increase with the increase of motion frequency when less than certain movement frequency, when higher than certain
Motion frequency delivery flow does not dramatically increase not only can reduce instead with the increase of reciprocating frequency N.This is because
Pump needs certain absorbent time in a reciprocation period, that is to say, that pump has certain self-priming time, moves back and forth
Period to reserve self-priming time, pump the volume that high pressure chest can be just efficiently used in water suction, if the period is too short, absorbent time is not
Enough, the high pressure chest of pump is filled water and begins to drain not yet, leads to flow-reduction.
Therefore, it is necessary to consider the diameter D of the setting plunger appropriate such as size, cost and delivery flow B (L/min) of pump
(mm), stroke S (mm) and the frequency N (rpm) moved back and forth.The present invention inventor by experiment obtain energy minimization volume and
Make while cost pump delivery flow and pressure energy meet home-use requirement for cleaning pump dimensional parameters.Define the flow of pump
It is the flow volume ratio of pump with the ratio between the volume of pump, which reflects the relationship between the water pumping ability of pump and the volume of pump,
The flow that those skilled in the art are intended to pump is the bigger the better, and such cleaning capacity is strong, while wishing that the volume of pump is smaller more again
Good, such jetting machine is more portable, so the bigger flow volume the more advantageous than this parameter.The inventor of the present invention passes through
Experiment show that the stroke range of plunger 45 is 3-16mm, and the diameter range of plunger is 6-16mm, for pump mechanical strength and
The considerations of assembly, the optional range of length of plunger was 45-100mm, therefore the value range of the volume pumped is 63000mm^3-
