In addition, in the above-described embodiment, with regard to extension tube 5, for example understand the structure that links outer tube 10 and inner tube 20, but be not limited thereto, also can form with a body.
(2. extension tube)
Secondly, forming to being shaped the outer tube body 11 of extension tube 5 and the material of interior tube body 21 that on electric dust collector 1, are equipped with describes.As mentioned above, the outer tube body 11 of formation extension tube 5 and interior tube body 12 are made up of the thermoplastic resin (being suitable for being below called " containing carbon fibre resin ") of the carbon fibre that contains regulation ratio.Below this is described containing carbon fibre resin.
(carbon fibre)
Be the fiber (short fiber) by the at high temperature carbonizations such as fibrous such as polyacrylonitrile (PAN) resin, spacing are obtained containing the contained carbon fibre of carbon fibre resin, it more than 90% is made up of carbon element conventionally.The concrete kind of this carbon fibre is not particularly limited, and can manufacture arbitrarily, and can use the goods of selling on market according to the physical property of carbon fibre described later under condition.Manufacturing carbon fibre in the situation that, it is created conditions, raw material etc. is not particularly limited, and uses known create conditions arbitrarily and raw material are manufactured.In addition, carbon fibre not necessarily must use separately a kind of, also can use by ratio and combination arbitrarily two or more.
Length containing the contained carbon fibre of carbon fibre resin is not particularly limited, preferably below 1mm.By using the carbon fibre of this length, can prepare more easily outer tube body 11 and the contained carbon fibre of interior tube body 21, therefore can cut down the manufacturing cost of extension tube 5.In addition, by the carbon fibre that makes outer tube body 11 and interior tube body 21 contain this length, carbon fibre each other form outer tube body 11 and interior tube body 21 contain carbon fibre resin in moderately stir together, its result, can have good rigidity.
Amount containing the contained carbon fibre of carbon fibre resin is more than 5 quality %, below 15 quality % containing in carbon fibre resin, preferably below 10 quality %.Amount by carbon fibre, within the scope of this, not only can suppress the manufacturing cost of extension tube 5, can also balance improves well lightness and the high rigidization of extension tube 5.In addition, also have advantages of easily above-mentioned upper cover 13 (with reference to Fig. 3) and cap assembly 23 (with reference to Fig. 5) ultrasonic wave coating outside on tube body 11 and interior tube body 21 respectively.About this point, be elaborated with reference to Figure 10.
Figure 10 is the curve obtaining according to the present inventor's research, is the curve of the relation of the tabular bending strength that contains carbon fibre resin of the thickness containing carbon fibre resin situation, tabular that schematically represents to make the amount of carbon fibre to change (external diameter during with shaping extension tube and the length of internal diameter poor corresponding) and this thickness.In Figure 10, near the record each curve is the amount (quality %) of carbon fibre (CF), and " PP " represents as the polypropylene (CF amount is 0 quality %) that does not contain the thermoplastic resin of carbon fibre.
In addition, " 86MPa " of the longitudinal axis represents the polyacrylic bending strength that the thickness that existing electric dust collector uses is 2mm.In the existing extension tube being made up of the polypropylene of thickness 2mm, the tabular polyacrylic bending strength that this extension tube is configured as when tabular is 86MPa.Therefore, as long as the bending strength of tabular resin more than 86MPa, can be used this tabular ester moulding at least to have and the extension tube of equal above intensity (rigidity) in the past.
Have, " 0.9 " mm of transverse axis is the MIN thickness that can carry out injection molding forming or blow molding again.Therefore, in the situation that carrying out injection molding forming or blow molding and being shaped extension tube, use tabular ester moulding very importantly, the thickness of extension tube is minimum is 0.9mm.
As shown in figure 10, in the situation that thering is same thickness, more increase containing the carbon fibre amount in carbon fibre resin, more increase containing the intensity (desirable strength) of carbon fibre resin.But the common price of carbon fibre is higher, in the case of the amount increase that makes carbon fibre, increase (price increase) containing the manufacturing cost in carbon fibre resin.And, if the thickness of extension tube is increased, cause thus the quality of extension tube also to rise (quality rising).In addition, according to the present inventor's research, polyacrylic proportion is 0.92g/cm
3, be 0.95g/cm with the ratio of for example 10 quality % containing the polyacrylic proportion of carbon fibre
3.Therefore, containing the polyacrylic proportion of carbon fibre, than polyacrylic than great containing carbon fibre, therefore, in the case of only making the containing increase of carbon fibre, even if thickness is identical, weight also increases.
, in order to improve the rigidity of extension tube 5 (more specifically saying outer tube main body 11 and interior tube body 21), even only make carbon fibre amount increase, can not manufacture at an easy rate extension tube 5, and weight also increases.And in the situation that weight becomes overweight, if reduce the thickness of extension tube 5, moulding described later becomes difficulty, cannot guarantee the common desired rigidity of extension tube 5.In addition, though for make thickness identical and make in order to manufacture at an easy rate extension tube 5 carbon fibre amount reduce, can not guarantee the common desired intensity of extension tube 5.Have, if increase the thickness of extension tube 5 in order to ensure rigidity, the weight of extension tube 5 likely becomes heavy (mass penalty) again.
Curve shown in Figure 10 is in view of above-mentioned problem, and the present inventor studies and the curve that obtains.The reduction (cheap) of the manufacturing cost while, manufacture, guarantee that extension tube 5 that common desired intensity, lightness all have both is to obtain by the present inventor's effort research.Namely, for example comprise polypropylene and 10 quality % ratio carbon fibre containing in carbon fibre resin, in the case of maintaining the intensity with mechanical strength of resin (being 86MPa as the tabular mechanical strength of resin) equal extent of existing formation extension tube, if thickness exceedes about 2mm, more in the past than the resin weight that formed extension tube.
Therefore, if making containing of carbon fibre proportional is more than 5 quality % and below 15 quality %, can reach and the intensity of resin equal extent that in the past formed extension tube, and can make Thickness Ratio in the past (approximately 2mm) thin, and then can make extension tube lighter than in the past.Particularly, because extension tube is tubular, therefore compare with the miscellaneous part that forms electric dust collector, have easily damaged situation, but there is the excellent results of light-duty (namely thin thickness) and high rigidity.By the carbon element resin that contains with such carbon fibre amount is applied to extension tube, can manufacture following extension tube: to make respectively the difference of external diameter and internal diameter be that 1mm is above and below 1.4mm to the length direction pars intermedia of tube body 11 and interior tube body 21 outside, and this difference is below 2mm in length direction Zone Full, thinner than in the past, light-duty and high rigidity.
In addition, according to the extension tube 5 forming containing carbon fibre resin that contains carbon fibre by ratios above with 5 quality % and below 15 quality %, by the above-mentioned upper cover 13 of ultrasonic wave coating and cap assembly 23, can fix more reliably.More particularly, have the amount that more increases carbon fibre, ultrasonic wave coating becomes more difficult tendency conventionally.But, according to the extension tube 5 that contains carbon fibre with aforementioned proportion, when maintaining above-mentioned cheapness, light-duty, high rigidity, also there is the fixing effect that can carry out more reliably upper cover 13 and cap assembly 23.Have again, by making thermoplastic resin contain carbon fibre with aforementioned proportion, thereby also have advantages of and utilize injection molding forming described later or blow molding to carry out to be especially easily shaped extension tube.
(thermoplastic resin)
Extension tube 5 is made up of the thermoplastic resin that contains above-mentioned carbon fibre.In the explanation of above-mentioned carbon fibre, be illustrated taking polypropylene as object lesson as thermoplastic resin, but the contained thermoplastic resin of extension tube 5 is not limited to polypropylene., as the thermoplastic resin of shaping extension tube 5, can use known thermoplastic resin arbitrarily (for example as mentioned above ABS (acrylonitrile-butadiene-styrene (ABS)) resin etc.), as long as its physical property possesses function as extension tube for arbitrarily.But, as the thermoplastic resin of shaping extension tube 5, according to viewpoint light-duty and cheap, that easily manufacture and process, as illustrated in above-mentioned concrete example, preferably use polypropylene.In addition, thermoplastic resin is not essential to use separately a kind ofly, can and be used in combination two or more with ratio arbitrarily yet.
In addition, extension tube 5 also can contain above-mentioned carbon fibre and thermoplastic resin any composition in addition.
Secondly, to forming being described by the outer tube body 11 forming containing carbon fibre resin and the manufacture method of interior tube body 21 of extension tube 5.In the present embodiment, outer tube body 11 and interior tube body 21 are shaped containing carbon fibre resin injection mould-forming or blow molding by making respectively.Below be divided into the situation of injection molding forming of carrying out, these two kinds of situation that carry out blow molding, externally the manufacture method of tube body 11 and interior tube body 21 describes.But, can similarly manufacture although outer tube body 11 and interior tube body 21 shapes are slightly different, therefore, describe as an example of the manufacture method of interior tube body 21 example in the following description.In addition, for simplicity of illustration, make the simple barrel shape that is shaped as of interior tube body 21 in Figure 11 and Figure 12.
(carrying out the situation of injection molding forming)
In the situation that use is carried out injection molding forming containing carbon fibre resin, its concrete method is not particularly limited.Below the method for injection molding forming is specifically described, but the method for injection molding forming is not limited to following content.For example, as shown in figure 11, the type heart 102 of the mould (patrix 100 and counterdie 101) of profile (the namely outward appearance of cylindrical shape) that can shaping drum shape, the internal diameter of the drum that can be shaped combines and the member that is made of one.And by connecting the through hole 102b of the flange 102a forming with the type heart 102, in the gap producing in the time that these are combined, after injection (namely releasing) heating, melted containing carbon fibre resin.Then cooling, and dismounting bed die 100,101 and the type heart 102, cut off as required flash, thereby can be shaped interior tube body 21.
Injection melted containing carbon fibre resin time mould 100,101 and the temperature of the type heart 102 be temperature arbitrarily, but in the case of containing at the temperature below the fusing point of carbon fibre resin, due to containing carbon fibre resin solidification, be therefore set as the temperature higher than this melting temperature.In addition, because the injection load in when injection is according to the temperature containing carbon fibre resin or composition and therefore difference cannot treat different things as the same, but can be for example about 200MPa.In addition the concrete device when carrying out injection moulding, the injection moulding forming machine that for example can use TOHKEMY 2010-131966 communique or TOHKEMY 2006-110905 communique etc. to record.
By utilizing the injection molding forming interior tube body 21 that is shaped, can precision form well external shape and the interior shape of interior tube body 21, can make the level and smooth member of inwall that makes interior tube body 21.Therefore, air, in the time of interior tube body 21 internal circulation using when electric dust collector, can reduce the internal drag of air, can further improve the running efficiency of the electric blower being equipped with on electric dust collector.In addition, the turbulent flow of the concavo-convex air causing of inwall can be suppressed, this turbulent noise can be further suppressed to follow.And, owing to can in an operation, extension tube entirety being shaped integratedly, therefore can realize the simplification of manufacturing process.
(carrying out the situation of blow molding)
In the situation that use is carried out blow molding containing carbon fibre resin, its concrete method is not particularly limited.Referring to Figure 12, the method for blow molding is specifically described, but the method for blow molding is not limited to following content.

Load, the concrete pressure of pressure-air etc. containing the temperature of carbon fibre resin, while releasing parison 202 to mould 200,201 inner surfaces that form parison 202 are not particularly limited, as long as be suitable for known blow-moulding process arbitrarily.In addition the concrete device when carrying out blow molding, the blow molding machine that can use such as Japanese kokai publication hei 11-277617 communique etc. to record.
By utilizing the blow molding interior tube body 21 that is shaped, can not use type heart be shaped in tube body 21, therefore can realize the simplification of the manufacturing process of the withdrawable type heart etc.Owing to can in an operation, interior tube body 21 entirety being shaped integratedly, therefore, according to this viewpoint, can also realize the simplification of manufacturing process.
As mentioned above, outer tube body 11 and interior tube body 21 can be manufactured at an easy rate, and light-duty and high rigidity.Namely, about the extension tube 5 of attaching usually used as accessory on electric dust collector, also can realize the raising of performance, and then the electric dust collector that electric dust collector overall performance is high can be provided.
In addition, as mentioned above, even if use containing carbon fibre resin, also can easily carry out injection molding forming or blow molding.Therefore, there is the advantage that the shaping of extension tube 5 (more particularly, outer tube body 11 and interior tube body 21) is easy and so on.In addition, by ultrasonic wave coating upper cover 13 and cap assembly 23, also can be with respect to the thermoplastic resin that contains carbon fibre easily and firmly fix.
