Embodiment
For making object, technological scheme and the advantage of the embodiment of the present invention clearer, below in conjunction with the accompanying drawing of the embodiment of the present invention, the technological scheme of the embodiment of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, rather than whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skills obtain under the prerequisite without creative work, belongs to the scope of protection of the invention.
Unless otherwise defined, technical term used herein or scientific terminology should be and in field, have the ordinary meaning that the personage of general technical ability understands under the present invention." first " of using in patent application specification of the present invention and claims, " second " and similar word do not represent any order, quantity or significance, and are just used for distinguishing different constituent elements.Equally, the similar words such as " " or " " do not represent restricted number yet, and mean and have at least one.
Fig. 1 is according to the cross section view of a kind of valve pump of the embodiment of the present invention.As shown in Figure 1, described valve pump comprises: combination brake switch and proporting 1, valve pipe 2, discharging portion 3, charging portion 4, linkage portion 6, cam 7 and motor 8.Wherein, combination brake switch and proporting 1 and valve pipe 2 have formed the valve system of valve pump, and discharging portion 3 and charging portion 4 have formed the feeding-discharging mechanism of valve pump, and linkage portion 6, cam 7 and motor 8 have formed the driving mechanism of valve pump.Pump chamber 5 is that it at least comprises the inner space of combination brake switch and proporting 1 and the inner space of valve pipe 2 at the inner cavity forming of valve pump, and can be communicated with discharging portion 3 and charging portion 4 by combination brake switch and proporting 1.The transfer space that this pump chamber 5 is materials.
The different piece of combination brake switch and proporting 1 coordinates with valve pipe 2, discharging portion 3 and charging portion 4 respectively, thereby realizes the unilaterally connected of valve pipe 2 and discharging portion 3, valve pipe 2 and charging portion 4.Valve pipe 2 has telescopic structure, and when it shrinks, material is pressed into discharging portion 3 by combination brake switch and proporting 1; When valve pipe 2 extends, material enters into valve pipe 2 inside from charging portion 4 through combination brake switch and proporting 1.
Discharging portion 3 and charging portion 4 respectively with the material pipeline connection of valve pump outside, and the conducting of being controlled between outside material pipeline and pump chamber 5 by combination brake switch and proporting 1.Structurally, discharging portion 3 and charging portion 4 can be one section of pipelines, and its spatial relationship can be mutually vertical as shown in Figure 1, also can become other angle.Discharging portion 3 and charging portion 4 can be also the combinations of interface or interface and pipeline.
Driving mechanism is flexible for drive control valve pipe 2.As shown in Figure 1, driving mechanism comprises linkage portion 6, cam 7 and motor 8.One end of linkage portion 6 is connected with cam 7, and cam 7 drives rotation by the output shaft of motor 8, thereby rotatablely moving of motor 8 output shafts is converted to the straight reciprocating motion of linkage portion 6.Be accompanied by the straight reciprocating motion of linkage portion 6, valve pipe 2 shrinks or extends.When linkage portion 6 is during to the direction straight line motion of valve pipe 2, valve pipe 2 is compressed like this; When linkage portion 6 is during to direction straight line motion away from valve pipe 2, valve pipe 2 extends.If one end that linkage portion 6 contacts with valve pipe 2 is not fixedly connected with valve pipe 2, so in linkage portion 6 during to direction straight line motion away from valve pipe 2, compressed valve pipe 2 can be replied elongation voluntarily.
Alternatively, one end of linkage portion 6 is fixedly connected with valve pipe 2, and when linkage portion 6 is during to the direction straight line motion of valve pipe 2, valve pipe 2 is compressed like this; When linkage portion 6 is during to direction straight line motion away from valve pipe 2, valve pipe 2 is stretched.Due to the stretching action of linkage portion 6, can accelerate valve pipe 2 and suck the speed of material, and owing to replying voluntarily elongation without valve pipe 2, can reduce the requirement to valve pipe 2 recovery characteristics, also can extend the life-span of valve pipe 2.
As shown in Figure 1, the housing parts of valve pump can comprise front cover portion 10A and main body 10B, and the two is realized and being connected by shell engaging mechanism CL.Wherein, at front cover portion 10A, form discharging portion 3 and charging portion 4, and the respective outer side edges of the structure of front cover portion 10A and combination brake switch and proporting 1, thereby for combination brake switch and proporting 1, provide support and locate; The space that main body 10B limits is provided with the assemblies such as valve pipe 2, linkage portion 6, cam 7 and motor 8, the structure of main body 10B also with the respective outer side edges of valve pipe 2, thereby for valve pipe 2, provide support and locate, and be the flexible space that provides of valve pipe 2.Shell engaging mechanism CL can connect or the mode such as be threaded realizes by riveted joint, buckle.Preferably, shell engaging mechanism CL is used buckle to connect and realizes, and easy accessibility, on the other hand, can locate accurately and can adjust by changing clamping contraposition position the direction of charging portion 4 front cover portion 10A on the one hand.Fig. 2 a is combination brake switch and proporting in the valve pump shown in Fig. 1 and the three-dimensional view of valve tubular portion, and Fig. 2 b is the cross section view of this combination brake switch and proporting and valve tubular portion.As shown in the figure, combination brake switch and proporting 1 comprises discharging guide portion 11, charging guide portion 12 and supporting portion 13.
The supporting effect to charging guide portion 11 and charging guide portion 12 can be played in supporting portion 13.On the one hand, in valve pump work process, charging guide portion 11 and charging guide portion 12 can be subject to the longitudinally active force of (as the longitudinal direction in Fig. 2 b), the bearing of trend of supporting portion 13 is parallel to this longitudinal direction, therefore can be for charging guide portion 11 and charging guide portion 12 provide support on this longitudinal direction; On the other hand, supporting portion 13 has certain length on its bearing of trend, between the plane that therefore can contact with supporting portion 13 at the open part of charging guide portion 12 and valve pipe 2, forms a space C.Space C provides space for the deformation of charging guide portion 12.
Because supporting portion 13 has opening 131, thereby space C is communicated with the inner space A of combination brake switch and proporting 1.Alternatively, supporting portion 13 can have one or more opening 131, and this opening 131 can take different shapes, for example, and the formed perforation of 13 Normal direction along supporting portion.
As depicted in figs. 1 and 2, the inner space A of combination brake switch and proporting 1 and the inner space B of the scalable part of valve pipe 2 are communicated with.Therefore, space C also belongs to a part for pump chamber 5.Like this, pump chamber 5 has just comprised the inner space A of combination brake switch and proporting 1, the inner space B of valve pipe 2 and space C.Supporting portion 13 can have central shaft symmetrical structure.
Valve tube opening part 21 has formed two circular opens of the different-diameter being interconnected.Wherein, the diameter of the circular open R1 that diameter is larger is greater than the maximum outside diameter of combination brake switch and proporting 1, and its degree of depth (corresponding to the aforementioned longitudinal direction in Fig. 2 b) matches with the height of supporting portion 13, thereby the supporting portion of combination brake switch and proporting 1 13 is put in the inner, and combination brake switch and proporting 1 is fallen in its radial plane in projection in the radial direction.In Fig. 2 a and Fig. 2 b, the degree of depth of the circular open R1 that described diameter is larger equals the height of supporting portion 13, and in other example, the degree of depth of circular open R1 also may be greater than or less than the height of supporting portion 13.
The less circular open R2 of diameter of valve tube opening part 21 has the diameter that is less than supporting portion 13 external diameters.Valve tube opening part 21 can provide support to supporting portion 13 like this, to realize the supporting effect of supporting portion 13.In Fig. 2 b, the diameter of the circular open R2 that the diameter of valve tube opening part 21 is less is less than the external diameter of supporting portion 13, but be greater than the internal diameter of supporting portion 13, like this can be so that this circular open be larger, be difficult for causing the motion bottleneck of material from the inner space B of valve pipe 2 to the inner space A of combination brake switch and proporting 1.Alternatively, the diameter of the circular open R2 of valve tube opening part 21 also can be equal to or less than the internal diameter of supporting portion 13.
Valve tube body part 22 is shunk or is extended under the effect of aforementioned driving mechanism, and material is pressed into space A from space B, or material is sucked to space B from space C.This shrinking structure can not produce the friction with other assembly, thereby is optimized working life yet.Consider the aforementioned structure of valve pipe 2, if by valve tube opening part 21 and 22 global analyses of valve tube body part, the space B being interconnected so and space C can be considered the same space, that is to say, during 22 compression of valve tube body part, the material of space B and space C is pressed into space A; When valve tube body part 22 is extended, the material of charging guide portion 12 outsides is drawn into space C and space B.
Alternatively, valve pipe 2 can also comprise fore-set 23.Fore-set 23 is arranged in the inner space B of valve pipe 2.The bottom of fore-set 23 is fixedly connected with the bottom inside of valve tube body part 22.When valve pump sucks material, fore-set 23, with the elongation campaign of valve tube body part 22, plays agitaion to entering the material of valve pipe 2.For the thick liquid materials such as liquid detergent, this agitaion can reduce liquid detergent viscosity and change the impact on flow especially, ensures that liquid detergent, with stable flow output, has stronger adaptability for winter and summer liquid detergent stickiness difference.
Combination brake switch and proporting 1 and valve pipe 2 can be discrete assemblies.Shown in Fig. 1, the position that the front cover portion 10A of valve pump casing can fixed Combination valve 1.Particularly, the counter structure interference fit of the excircle of charging guide portion 12 and front cover portion 10A, the upper-end surface of charging guide portion 12 is offseted with the plane contact that matches of front cover portion 10A under the effect of supporting portion 13, thereby can limit combination brake switch and proporting 1, move upward, and can play plane sealing effect; The supporting portion 13 of combination brake switch and proporting 1 has aforesaid contact and supporting relation with the valve tube opening part 21 of valve pipe 2, thereby can limit combination brake switch and proporting 1, moves downward.
Alternatively, combination brake switch and proporting 1 also has boss part 14, as shown in Figure 1, Figure 2 shown in a, Fig. 2 b and Fig. 3.This boss part 14 can embed the counter structure of front cover portion 10A, strengthens fixing combination brake switch and proporting 1.The groove forming between boss part 14 and charging guide portion 12 can play anticreep and axially locating effect.Adapt with the axially symmetric structure of combination brake switch and proporting 1, boss part 14 can be circular boss structure.
As previously mentioned, the cooperating structure of the main body 10B of valve pump casing inner side can be realized the position of valve pipe 2 is fixed by the valve tube opening part 21 of standing valve pipe 2.
According to other embodiments of the invention, combination brake switch and proporting 1 and valve pipe 2 can be also integrated.
Fig. 3 is the three-dimensional view of the combination brake switch and proporting in Fig. 2 a and Fig. 2 b.As previously mentioned, combination brake switch and proporting 1 comprises discharging guide portion 11, charging guide portion 12 and supporting portion 13.As shown in Figure 3, the top of discharging guide portion 11 be valve nozzle structure, the bottom of flexible flat shape be columnar nozzle structure, valve nozzle structure with nozzle structure between transition structure by a flat taper be communicated with.This structure of discharging guide portion 11 can realize material from the inner space of combination brake switch and proporting 1 one-way conduction to space outerpace.When the pressure of the material of discharging guide portion 11 inside acquires a certain degree, can be so that there is certain deformation in flexible valve mouth, and open, thereby allow material output.The slit opening structure of the transition structure of columnar nozzle structure, flat taper and valve nozzle matches, and can increase the extrusion pressure of material.
In Fig. 3, the slit opening structure of valve nozzle is positioned at the top of discharging guide portion 11, and alternatively, this slit opening also can be arranged at the other parts of discharging guide portion 11, for example side.
Charging guide portion 12 is down umbrella shape, and is arranged on the nozzle structure bottom of discharging guide portion 11.Charging guide portion 12 has central shaft symplex structure, and its central shaft overlaps with the symmetry axis of discharging guide portion 11, and charging guide portion 12 has the through-hole structure being connected with the nozzle structure of discharging guide portion 11.Can there is repeated deformation because it is flexible in the edge of guide portion 12, thereby realize the function of one-way valve.
Supporting portion 13 is arranged on charging guide portion 12 bottoms.As shown in the figure, supporting portion 13 can comprise a plurality of stiffening ribs, and the interval between stiffening rib has formed aforesaid opening 131, as inner space and one of outside passage being communicated with of combination brake switch and proporting 1.
Discharging guide portion 11, charging guide portion 12, supporting portion 13 and optional boss part 14 can be discrete parts, by assembling, form combination brake switch and proporting 1.Preferably, discharging guide portion 11, charging guide portion 12, supporting portion 13 and boss part 14 can be also integrated.Can make by mold integral.This integrative-structure, due to the physical connection without between discharging guide portion 11 and charging guide portion 12 and charging guide portion 12 and supporting portion 13, can be realized better connection and sealing effect.Combination brake switch and proporting 1 can be made with flexible (flexible) material monolithic.
Combination brake switch and proporting 1 or its unitary part (discharging guide portion 11, charging guide portion 12 and supporting portion 13) can be in following material one or more make: natural rubber, butyl rubber, styrene butadiene rubber, polyisoprene, ethylene, propylene, silicone, nitrite rubber, chlorination nitrite rubber, ethylene propylene diene rubber, Fluorosilicone elastomers, fluorocarbon elastomer etc.
Fig. 4 a is the cross section view of the valve pipe in Fig. 2 a and Fig. 2 b.As shown in Fig. 4 a, fore-set 23 can have irregular cylindrical shape, and for example, up-thin-low-thick cylindrical shape, can strengthen stirring action like this.Meanwhile, fore-set 23 also can have certain diameter, to increase the area of contact with material, strengthens stirring action, but also can not take too much the inner space of valve tube body part 22, affect the amount that valve pipe 2 stores materials.In addition, preferably, fore-set 23 inner hollow, material can't enter the inside of fore-set 23.This hollow structure can reduce the quality of fore-set 23, reduces compression and stretching valve pipe 2(valve tube body part 22) operating load.
Within fore-set 23 can be installed on valve tube body part 22, also can be one-body molded with valve tube body part 22.If fore-set 23 is one-body molded with valve tube body part 22, can there be better connection and sealing effect.Equally, valve pipe 2 can be also integrated on the whole.
Fig. 4 b shows the example of the another kind of structure of valve pipe 2.As shown in Figure 4 b, fore-set 23 is one-body molded with valve tube body part 22, and in fact fore-set 23 becomes a part for the outer wall of valve tube body part 22.This one-time formed manufacture, can remove the step that fore-set 23 is installed from, also can have better sealing and be connected effect.
Fig. 5 is the valve pump of Fig. 1 work schematic diagram in outside discharging process.When outside discharging, the valve tube body part 22 of valve pipe 2 is compressed, be stored in the inner space A that material in valve tube body part 22 inner space B is pressed into combination brake switch and proporting 1, and further the valve nozzle of the discharging guide portion 11 by combination brake switch and proporting 1 enters into discharging portion 3, thereby to the outside output of valve pump.
Because the charging guide portion 12 of combination brake switch and proporting 1 is subject to the restriction of charging portion 4 outer walls, can not be to the direction of charging portion 4 (in Fig. 5 vertically upward direction) Bending Deformation, therefore the material in the C of space can not enter into charging portion 4 by charging guide portion 12, and this is the effect of charging guide portion 12 one-way conductions namely.
In Fig. 5, between charging guide portion 12 and the inner space of charging portion 4, can have inner space D.Corresponding to the circular open of charging guide portion 12, inner space D also has annular shape.Thus, when the body portion 22 of valve pipe 2 shrinks, material is pressed into space A and C from space B, but can not enter into space D, thereby can not enter into charging portion 4.Inner space D also can adopt other shape.For example, when charging guide portion 12 is semi-circular or other one-sided configuration, inner space D also has the shapes such as semi-circular.
The fore-set 23 of valve pipe 2, after valve tube body part 22 is shunk, can all still be stayed in the inner space B of valve pipe 2, also can partly enter the inner space A of combination brake switch and proporting 1, but not contact with the inwall of combination brake switch and proporting 1, prevents combination brake switch and proporting 1 to cause unnecessary extruding.
Fig. 6 is the valve pump of Fig. 1 work schematic diagram in inside fill process.When inside charging, the valve tube body part 22 of valve pipe 2 is extended, at inner space B, form negative pressure, thereby make also to form negative pressure in the inner space A that is communicated with space B and C, but because this negative pressure of valve nozzle structure of discharging guide portion 11 can not make this valve nozzle open, now inner space A is not communicated with the inner space of discharging portion 3 thus.Under the effect of negative pressure, the downward deformation of the edge of charging guide portion 12 meeting crooked (deflection), thus the material of charging portion 4 inner spaces (alternatively, through space D) enters into space C, then enters into the inner space B of the valve tube body part 22 of valve pipe 2.Same, the charging guide portion 12 of combination brake switch and proporting 1 can be loop configuration, can be also one-sided configuration, all can serve as the unidirectional pilot valve of charging portion 4.
Fig. 7 a is according to the cross section view of the another kind of valve pump of the embodiment of the present invention, and Fig. 7 b is the three-dimensional appearance view of this valve pump.Mainly be with the valve pump difference of Fig. 1, in the valve pump of Fig. 7 a and Fig. 7 b, the mouth of pipe or the pipeline of discharging portion 3 and charging portion 4 are parallel.This parallel structure can realize and the docking of exterior line better, also can save space.In addition, rubber stopper 9 is used for filling up the auxiliary hole staying after processing, plays seal action.
From Fig. 7 b, also can find out front cover portion 10A, main body 10B and the shell engaging mechanism CL of aforesaid valve pump casing.In the scheme shown in Fig. 7 b, the mode that shell engaging mechanism CL has adopted buckle to connect.As previously mentioned, the mode that buckle connects can be so that adjust contraposition position when front cover portion 10A is installed, thereby change the spatial position of discharging portion 3 and charging portion 4.
Fig. 8 is the valve pump of Fig. 7 a and the 7b work schematic diagram in outside discharging process.Fig. 8 is identical with the working principle shown in Fig. 5.When outside discharging, the valve tube body part 22 of valve pipe 2 is compressed, be stored in the inner space A that material in valve tube body part 22 inner space B is pressed into combination brake switch and proporting 1, and further the valve nozzle of the discharging guide portion 11 by combination brake switch and proporting 1 enters into discharging portion 3, thereby to the outside output of valve pump.
