And this bubble generator 100 makes minimum Bubble formation in the liquid such as running water or hot water of discharging from discharge member 200.Therefore, the applicable liquid of this bubble generator 100 is not limited to shower water or rinse water, preferably produces other liquid of minimum bubble, and such as liquid fertilizer or treatment fluid etc. also can be used as object.
As shown in Figures 2 to 7, bubble generator 100 is made up of upstream side main body 10, flow divider 30 and downstream side main body 20, wherein upstream side main body 10 arranges the first stream 11 narrowing towards downstream side, flow divider 30 is accommodated in the first stream 11 and multiple liquid-through holes 31 is set, downstream side main body 20 is installed on upstream side main body 10, and the second stream 21 broadening towards downstream side is set.In addition, this bubble generator 100 is in order successfully to supply with the interior flowing liquid of the first stream 11 in upstream side main body 10 in the second stream 21 of downstream side main body 20, make the downstream side end of the first stream 11 relative with the upstream side end of the second stream 21 to.
; as used in Fig. 5 as shown in arrow; this bubble generator 100 is during supplying with the second stream 21 from the downstream side main body 20 that is positioned at diagram downside; make minimum Bubble formation in supplying with the liquid of upstream side main body 10 sides from pressure fluid supply member 210 in inside; and, minimum bubble is sneaked into the liquid of discharging from the second stream 21.In addition, the bubble generator 100 shown in Fig. 1 turns upside down with the bubble generator 100 shown in Fig. 5.
In this bubble generator 100, minimum bubble produces as follows.First, supply with the liquid in upstream side main body 10, by flowing into interior shunting of each liquid-through hole 31 of flow divider 30, be expelled in the first stream 11 on one side on one side.Because this first stream 11 narrows towards downstream side, therefore, on one side by the liquid compression being expelled in the first stream 11, send into downstream side on one side.Due to the downstream side end of this first stream 11, relative with the upstream side end of the second stream 21 that is formed at downstream side main body 20 to, therefore, liquid flows in the second stream 21 from the first stream 11.Because this second stream 21 broadens towards downstream side, therefore, in its downstream side end, the pressure of liquid sharply declines.
In above each stage, owing to being not only applied in various shear stresses on liquid, and also pressurized and opened, therefore, in liquid, produce cavitation erosion.And, even the flowing of the interior generation complicated shape of bubble generator 100, not only these each power this as larger, and, this utmost point short stroke in the first stream 11 and the second stream 21,,, in the utmost point short time, these each power are applied in or are opened, therefore, dissolving in gas componant in liquid becomes bubble by cavitation erosion and occurs, atomic little bubble, is micron bubble.
According to inventor's experiment, in liquid, produce cavitation erosion by using this bubble generator 100 and can consider due to following reason.In the time using this bubble generator 100, in the time that liquid passes through the opening 11a of the first stream 11 of upstream side main body 10, due to the effect of rotating flow, in liquid stream, be formed centrally gas axle (vacuum shaft).On the other hand, can consider in the time that liquid is discharged to the second stream 21 from the opening 21a of downstream side main body 20, by the wall of liquid around, central portion be flowed.Therefore, can consider to be introduced into the liquid of gas axle side and clash from the liquid of the radial ejection of opening 21a, and the gas of gas axle is sheared and produces minimum bubble (micron bubble).
In general, the steam or the bubble that produce due to cavitation erosion are absorbed in liquid at short notice again, but, because the bubble resulting from bubble generator involved in the present invention 100 is this minimum bubble of micron bubble, therefore, because surface tension etc. can not be absorbed in liquid at short notice again.In other words, make micron bubble, minimum bubble residues in the liquid of discharging from the second stream 21, if this liquid is used as the shower water from for example shower nozzle 200, can have one's hair wash or health cleaning with high cleaning force.
Therefore, in the related bubble generator 100 of this invention first aspect, can generate minimum bubble, and be suitable for shower nozzle 200, for the water bolt of running water, to the pipe arrangement of bathroom or tank and dish cleaning machine etc., for the watering spray of gardening.
In order to solve above-mentioned problem, the method that the related invention of invention second aspect is taked is about the bubble generator 100 described in foregoing invention first aspect, that is: " at least any surface roughness Ra of the bearing surface 25 of the bearing surface 15 of the upstream side main body 10 of mutual butt or downstream side main body 20 is made as to 0.2～6.3, and extraneous air can be imported inner from the fine gap of 15/25 of these bearing surface ".
The related bubble generator 100 of this invention second aspect is as illustrated in the bubble generator 100 of foregoing invention first aspect, formed by upstream side main body 10, flow divider 30 and downstream side main body 20, wherein upstream side main body 10 arranges the first stream 11 narrowing towards downstream side, flow divider 30 is accommodated in the first stream 11 and multiple liquid-through holes 31 is set, downstream side main body 20 is installed on upstream side main body 10, and the second stream 21 broadening towards downstream side is set.And for the liquid flowing in the first stream 11 of upstream side main body 10 is successfully supplied with in the second stream 21 of downstream side main body 20, make the downstream side end of the first stream 11 relative with the upstream side end of the second stream 21 to.
; as used in Fig. 5 as shown in arrow; in this bubble generator 100, supply with the liquid of upstream side main body 10 sides from pressure fluid supply member 210 in the time that supply is positioned at the diagram upper end of the second stream 21 of the downstream side main body 20 of diagram downside, in this feed fluid, produce negative pressure.
On the other hand, as shown in Figure 5 and Figure 6, due at least any surface roughness Ra of the bearing surface 25 of the bearing surface 15 of the upstream side main body 10 of mutual butt or downstream side main body 20 is made as to 0.2～6.3, therefore, be formed with fine gap 15/25 of these bearing surface.Therefore,, in the time supplying with the liquid supply downstream side main body 20 of upstream side main body 10 sides, as long as produce negative pressure in this feed fluid, by this negative pressure, extraneous air imports the inside of this bubble generator 100 from the fine gap of 15/25 of bearing surface.
, the surface roughness Ra of any of the bearing surface 25 of the bearing surface of upstream side main body 100 15 or downstream side main body 20 must be made as to 0.2～6.3 here, it be the reasons are as follows.First, in the time that the surface roughness Ra of the bearing surface 15 of upstream side main body 10 or the bearing surface 25 of downstream side main body 20 is less than 0.2, not only because the gap of 15/25 of bearing surface compared with little and can not carry out the importing of extraneous air, and, because be only that cost cost does not have meaning to the processing of such surface roughness.On the other hand, in the time that the surface roughness Ra of the bearing surface 15 of upstream side main body 10 or the bearing surface 25 of downstream side main body 20 is greater than 6.3, it is excessive and can carry out simply the importing of extraneous air that gap that bearing surface is 15/25 becomes, but, become the reason of " leak of liquid " of this bubble generator 100.
In addition, surface roughness Ra must be made as to 0.2～6.3rd, the bearing surface 15 of upstream side main body 10 or the bearing surface 25 of downstream side main body 20 at least any, be not must be the bearing surface 15 of upstream side main body 10 and the bearing surface 25 of downstream side main body 20 two.But, if certainly the surface roughness Ra of two of the bearing surface 25 of the bearing surface of upstream side main body 10 15 and downstream side main body 20 is made as to 0.2～6.3, just easily carry out the control of micro-bubble generation described later.
So, because the extraneous air that imports the inside of bubble generator 100 from the gap of 15/25 of the bearing surface as above-mentioned roughness is scattered in liquid at upstream side main body 10 and the boundary member of downstream side main body 20, therefore, become the micro-bubble that diameter is millimeter unit, and this micro-bubble is sneaked into the liquid of discharging from the second stream 21 of downstream side main body 20 together with minimum bubble.This micro-bubble is known in such as above-mentioned patent documentation 1 or 2 etc.
Therefore, in the related bubble generator 100 of this invention second aspect, can generate minimum bubble and micro-bubble simultaneously, be suitable for shower nozzle 200, for the water bolt of running water, to the pipe arrangement of bathroom or tank and dish cleaning machine etc., for the watering spray of gardening.
In order to solve above-mentioned problem, the method that the related invention of the invention third aspect is taked is to be about the bubble generator 100 described in foregoing invention first aspect or invention second aspect, that is: " axle center of each liquid-through hole 31 that makes flow divider 30 with respect to the axle center of this flow divider 30 and tilt ".
; as shown in Fig. 4 (a) and Fig. 5; in the bubble generator 100 of this invention third aspect; the axle center of each liquid-through hole 31 that makes flow divider 30 is with respect to the axle center of this flow divider 30 and tilt; thus, further will put in the liquid being flowing in each liquid-through hole 31 for generation of the power of minimum bubble.
In the time that each liquid-through hole 31 tilts with respect to the axle center of this flow divider 30, make the axis direction flowing liquid rotation along this flow divider 30, and for the revolving force of this liquid as being applied in sharp along with the shear stress of going direction changing, further promote the sectionalization of the bubble producing due to cavitation erosion, and further promote the generation of minimum bubble.
Therefore,, the related bubble generator 100 of this invention third aspect function same with foregoing invention first aspect or invention second aspect except performance, also further promote the generation of minimum bubble.
Moreover, in order to solve above-mentioned problem, the method that the related invention of invention fourth aspect is taked be about foregoing invention first aspect to the bubble generator 100 described in either side in the invention third aspect be that is: " between upstream side main body 10 and downstream side main body 20, to form space 40 ".
As shown in Figure 5, the bubble generator 100 of this invention fourth aspect forms space 40 between upstream side main body 10 and downstream side main body 20, and mutually relatively to the downstream side end of the first stream 11 and the upstream side end of the second stream 21 for the time being can be at these space 40 openings.Particularly, the downstream side that makes the first stream 11 in this space 40 is open-ended is to produce the negative pressure being produced by Venturi effect the liquid flowing out from the downstream side end of this first stream 11.
If Gai space, upstream side end 40 openings of the downstream side end of these the first streams 11 and the second stream 21, liquid is in the time flowing out to space 40 from the downstream side end of the first stream 11, or when upstream side endwall flow from from this space 40 to the second stream 21, be subject to sharp the resistance of the constructivity of bubble generator 100, and pressure changes, become the reason producing for the cavitation erosion of this liquid, and carry out more the sectionalization of bubble.
Therefore, the related bubble generator 100 of this invention fourth aspect except performance with foregoing invention first aspect to the same function of the either side in the invention third aspect, also further promote the generation of minimum bubble.
In addition, the method of inventing the related invention employing in the 5th aspect is to be that is: " to make the size of the opening 11a of the downstream side end that is positioned at the first stream 11 be less than the opening 21a of the upstream side end that is positioned at the second stream 21 " about foregoing invention first aspect to the bubble generator 100 described in the either side of invention fourth aspect.
As shown in Figure 5, in bubble generator 100 aspect this invention the 5th, make the size of the opening 11a of the downstream side end that is positioned at the first stream 11 be less than the opening 21a of the upstream side end that is positioned at the second stream 21, thus, when liquid flows out to space 40 from the downstream side end of the first stream 11, or when upstream side endwall flow from from this space 40 to the second stream 21, more sharp liquid is bestowed the resistance of the constructivity of bubble generator 100, and pressure changes, become the reason producing for the cavitation erosion of this liquid, and carry out more the sectionalization of bubble.
Therefore, the related bubble generator 100 in this invention the 5th aspect except performance with foregoing invention first aspect to the same function of the either side in invention fourth aspect, also further promote the generation of minimum bubble.
And, in order to solve above-mentioned problem, inventing the method that the 6th related invention in aspect takes is to be about the bubble generator 100 described in foregoing invention fourth aspect or invention the 5th aspect, that is: " in upstream side main body 10 or downstream side main body 20, install and there is mouthfuls 51 the extraneous air of being taken into that is communicated in space 40 and be taken into member 50, and described minimum bubble and micro-bubble can be resulted from described liquid ".
; as shown in Figure 5; the extraneous air that is taken into mouth 51 that bubble generator 100 installations of this invention the 6th aspect have connected space 40 is taken into member 50; this extraneous air is taken in member 50; if this is taken into mouth 51 and is communicated in space 40, also can be installed on any of upstream side main body 10 or downstream side main body 20.
Because being taken into member 50, extraneous air is communicated in space 40 by being taken into mouth 51, and flow out to this space 40 at liquid from the downstream side end of the first stream 11 and produce negative pressure when interior, therefore, this bubble generator 100 negative pressure in space 40 in function puts on this extraneous air and is taken into member 50 by being taken into mouthfuls 51.In the time that this negative pressure puts on extraneous air and is taken into member 50, extraneous air is taken into member 50 and by being taken into mouthfuls 51, extraneous air is imported in space 40, and this extraneous air becomes micro-bubble by the liquid stream in space 40.

As shown in Figures 2 to 7, bubble generator 100 is made up of upstream side main body 10, flow divider 30 and downstream side main body 20, wherein upstream side main body 10 arranges the first stream 11 narrowing towards downstream side, flow divider 30 is accommodated in the first stream 11 and multiple liquid-through holes 31 is set, downstream side main body 20 is installed on upstream side 10, and the second stream 21 broadening towards downstream side is set.In addition, as shown in Figure 5, this bubble generator 100 make the downstream side end of this first stream 11 relative with the upstream side end of the second stream 21 to.In addition, the bubble generator 100 shown in this Fig. 5 shows as and turning upside down shown in Fig. 1.
Upstream side main body 10 interconnects by its each second stream 21 and 24 with downstream side main body 20, seal 16 is installed in this connecting portion and prevents leak of liquid.In the bubble generator 100 of present embodiment, as shown in Figure 5, in the time that these upstream side main bodys 10 are connected with downstream side main body 20, between upstream side main body 10 and downstream side main body 20, form space 40.And the size that is positioned at the opening 11a of the downstream side end of the first stream 11 that is formed at upstream side main body 10 is less than the opening 21a of the upstream side end that is positioned at the second stream 21 that is formed at downstream side main body 20.
In open end (upper end side of Fig. 5 the first stream 11) part of the first stream 11 that is arranged in upstream side main body 10, be formed with mounting stage portion 12, in this mounting stage portion 12, storage is placed with flow divider 30.As shown in Fig. 4 (a), this flow divider 30 is formed with multiple liquid-through holes 31, and these liquid-through holes 31 tilt its axle center with respect to this bubble generator 100.In addition, be formed with rectification projection 32 at the outstanding up and down of this flow divider 30, and make the laterally inclined of these rectification projections 32.This heeling condition is the heeling condition that approaches the inner face of the first stream 11, thus, in the liquid stream that flows in the first stream 11, can not form significantly delay part.In addition, this heeling condition forms steep anxious for the rectification projection 32 of downside shown in Fig. 5, form slowly for the rectification projection 32 of upside.
As shown in Figure 5 and Figure 6, in the related bubble generator 100 of present embodiment, at least any surface roughness Ra of the bearing surface 25 of the bearing surface 15 of the upstream side main body 10 of mutual butt or downstream side main body 20 is made as to 0.2～6.3 here.For this reason, form fine space 15/25 of these bearing surface.Therefore,, in the time being supplied in the liquid supply downstream side main body 20 of upstream side main body 10 sides, in the time producing negative pressure in this feed fluid, due to this negative pressure, extraneous air imports the inside of this bubble generator 100 from the fine gap of 15/25 of bearing surface.
As shown in Figure 5 and Figure 6, in the bubble generator 100 of present embodiment, than the inside of 15/25 of bearing surface, be provided with the seal 16 for preventing leak of liquid, its cross section is formed anti-U font by the seal 16.The seal 16 easily allows the importing from the extraneous air in the gap of 15/25 of bearing surface, on the contrary, easily prevents the caused leak of liquid of hydraulic pressure by the inside from this bubble generator 100.
As shown in Figures 1 to 7, the bubble generator 100 of present embodiment possesses extraneous air and is taken into member 50.This extraneous air is taken into member 50 and is connected in downstream side main body 20 sides and as parts of gas generator 100, its inside can be communicated in above-mentioned space 40 by being taken into mouthfuls 51.In addition, mouthfuls 51 can be communicated in space 40 if this extraneous air is taken into being taken into of member 50, also may be embodied to and be connected in upstream side main body 10 sides.
As shown in Figure 5, extraneous air is taken into member 50 and possesses the valve body 52 that is accommodated in the part that forms the outside that is taken into mouthfuls 51 and the valve seat 54 of this valve body 52 butts, in gas generator 100 sides of this valve body 52, dispose spring 53, this spring 53 always forces in this valve body 52 and the opposition side of bubble generator 100.In addition, the power that applies of this spring 53 is adjusted with the integrated adjustment screw 55 of valve body 52 by protruding from outside.Moreover this extraneous air is taken in member 50, at valve body 52 and valve seat 54 not when butt, by adjusting screw 55 around, and make to be outsidely communicated with space 40 is interior.
So, if being taken into member 50, this extraneous air reduces by the adjustment of adjusting screw 55 power that spring 53 applies, even the constant large state that can fully be taken into extraneous air that also forms of the negative pressure in space 40, on the contrary, if it is large that the power that applies of this spring 53 becomes, and if the constant large formation of the negative pressure in space 40 can not be taken into the state of extraneous air.Certainly, even in the situation that being taken into member 50 by this extraneous air and not being taken into extraneous air, that is, the situation that micro-bubble does not produce, also by the essential structure of bubble generator 100, " minimum bubble " self also produces certainly.
In addition, this extraneous air is taken into member 50 and also possesses the function of " check-valves ".,, the in the situation that of producing abnormal pressure in the first stream 11 or the second stream 21 sides, because this pressure puts on valve body 52 by being taken into mouth 51, therefore, this valve body 52 prevents leak of liquid with valve seat 54 butts.
