(2. extension tube)
Secondly, to shaping the outer tube body 11 constituting extension tube 5 provisioned on electric dust collector 1 and interior
The material of tube body 21 illustrates.As it has been described above, constitute outer tube body 11 and the inner tube master of extension tube 5
Body 12 (is suitable to referred to as " containing carbon fibre below by the thermoplastic resin of the carbon fibre containing regulation ratio
Resin ") constitute.Hereinafter this resin Han carbon fibre is illustrated.
(carbon fibre)
It is by by fibrous such as polyacrylonitrile (PAN) containing the carbon fibre contained by carbon fibre resin
The at high temperature carbonization such as resin, spacing and the fiber (chopped fiber) that obtains, generally it is more than 90% by carbon element
Constitute.The concrete kind of this carbon fibre is not particularly limited, according to the physical property of carbon fibre described later
Matter can manufacture under any conditions, and can also use the goods sold on market.Manufacturing carbon element
In the case of fiber, its manufacturing condition, raw material etc. are not particularly limited, and use known arbitrary manufacture
Condition and raw material carry out manufacturing.It addition, carbon fibre not necessarily must be used alone one, it is possible to
To use two or more by arbitrary ratio and combination.
Length containing the carbon fibre contained by carbon fibre resin is not particularly limited, preferably below 1mm.
By using the carbon fibre of this length, it is possible to prepare outer tube body 11 and interior tube body more easily
Carbon fibre contained by 21, therefore, it is possible to cut down the manufacturing cost of extension tube 5.It addition, outside by making
Tube body 11 and the interior tube body 21 carbon fibre containing this length, carbon fibre is constituting outer tube each other
Moderately stirring together containing in carbon fibre resin of main body 11 and interior tube body 21, it is as a result, it is possible to tool
There is good rigidity.
Amount containing the carbon fibre contained by carbon fibre resin be 5 mass % in containing carbon fibre resin with
Below upper, 15 mass %, below preferably 10 mass %.By the amount of carbon fibre within the range,
The manufacturing cost of extension tube 5 can not only be suppressed, additionally it is possible to balance improves the light-duty of extension tube 5 well
Change and high rigidization.It addition, also have easily by above-mentioned upper cover 13 (with reference to Fig. 3) and cap assembly 23
Advantage on (with reference to Fig. 5) ultrasonic wave coating tube body 11 outside respectively and interior tube body 21.About this
Point, is described in detail with reference to Figure 10.
Figure 10 is the curve that the research according to the present inventor obtains, and is to show schematically to make carbon element fine
Situation, the tabular thickness containing carbon fibre resin that the amount of dimension has changed is (during with shaping extension tube
External diameter and the length of internal diameter poor corresponding) and the bending containing carbon fibre resin of tabular of this thickness strong
The curve of the relation of degree.In Figure 10, the record near each curve is the amount (matter of carbon fibre (CF)
Amount %), " PP " is denoted as the polypropylene of the thermoplastic resin without carbon fibre (CF amount is 0 matter
Amount %).
It addition, " 86MPa " of the longitudinal axis represents that the thickness that existing electric dust collector is used is 2mm's
Polyacrylic bending strength.I.e. in the existing extension tube being made up of the polypropylene of thickness 2mm, should
The polyacrylic bending strength of tabular when extension tube is configured to tabular is 86MPa.Therefore, if tabular tree
The bending strength of fat at more than 86MPa, then can use this sheet-like resin to shape and at least have with the most same
Extension tube etc. above intensity (rigidity).
Further, " 0.9 " mm of transverse axis is the bottom line that can carry out injection molding forming or blow molding
Thickness.Therefore, carrying out injection molding forming or blow molding in the case of shaping extension tube, using
Sheet-like resin shape it is extremely important that, the minimum 0.9mm of thickness of extension tube.
As shown in Figure 10, in the case of there is same thickness, containing the carbon fibre in carbon fibre resin
Amount more increases, and the intensity (desirable strength) containing carbon fibre resin more increases.But, carbon fibre
Generally price is higher, in the case of the amount making carbon fibre increases, containing the system in carbon fibre resin
Cause this increase (price rising).Further, if making the thickness of extension tube increase, the most thus cause extending
The quality of pipe also rises (quality rising).It addition, according to the research of the present inventor, polyacrylic
Proportion is 0.92g/cm3, the polyacrylic proportion containing carbon fibre with the ratio of such as 10 mass % is
0.95g/cm3.Therefore, the polyacrylic proportion containing carbon fibre is than the polyacrylic proportion without carbon fibre
Greatly, therefore, only make carbon fibre containing increase in the case of, even if thickness is identical, weight also increases.
I.e., in order to improve the firm of extension tube 5 (outer tube body 11 and interior tube body 21)
Property, even if only making the amount of carbon fibre increase, can not be manufactured inexpensively extension tube 5, and weight
Also increase.Further, weight become overweight in the case of, if reduce extension tube 5 thickness, the most described later
Molding becomes difficulty, it is impossible to guarantee the rigidity that extension tube 5 is generally required.Even if it addition, in order to make thickness
Identical and make the amount of carbon fibre reduce to be manufactured inexpensively extension tube 5, can not guarantee to prolong
The intensity that long tube 5 is generally required.If further, increase the thickness of extension tube 5 in order to ensure rigidity,
Then the weight of extension tube 5 likely becomes weight (quality increase).
Curve shown in Figure 10 is in view of above-mentioned problem, the song that the present inventor carries out studying and obtains
Line.The reduction (cheap) of manufacturing cost when i.e., manufacturing, guarantee generally required intensity, light-duty
Changing the extension tube 5 all having both is to be studied by the effort of the present inventor and obtain.It is,
Such as comprise the carbon fibre of ratio of polypropylene and 10 mass % containing in carbon fibre resin,
Maintain the mechanical strength of resin (mechanical strength of resin as tabular is 86MPa) with existing composition extension tube equal
In the case of the intensity of degree, if thickness exceedes about 2mm, constitute the resin weight of extension tube the most than ever.
Therefore, if making the content ratio of carbon fibre is below more than 5 mass % and 15 mass %, then can
The intensity of the resin equal extent enough reached and in the past constituted extension tube, and also thickness can be made than ever
(about 2mm) is thin, and then extension tube can be made the lightest.Especially since extension tube is tubular,
Therefore, compared with the miscellaneous part constituting electric dust collector, there is the most damaged situation, but have light
Type (namely thickness is thin) and the excellent results of high rigidity.By having such carbon fibre amount
The resin containing carbon element be applied to extension tube, it is possible to manufacture following extension tube: tube body 11 and inner tube master outside
The length direction pars intermedia of body 21 makes external diameter be more than 1mm and below 1.4mm with the difference of internal diameter respectively,
And this difference is below 2mm in length direction Zone Full, the thinnest, light-duty and high rigidity.
It addition, according to by the carbon containing containing carbon fibre with the ratio more than 5 mass % and below 15 mass %
The extension tube 5 that cellulose fiber resin is constituted, the upper cover 13 above-mentioned by ultrasonic wave coating and cap assembly 23, energy
Enough more reliably fix.More specifically, there is the amount more increasing carbon fibre, usual ultrasound wave
Deposition becomes the most difficult tendency.But, according to containing the extension tube 5 of carbon fibre with aforementioned proportion, dimension
While holding above-mentioned rigidity cheap, light-duty, high, also have and can carry out upper cover 13 and cover more reliably
The fixing effect of parts 23.Further, by making thermoplastic resin contain carbon fibre with aforementioned proportion,
Thus also have and utilize injection molding forming described later or blow molding to be particularly easy to shape the excellent of extension tube
Point.
(thermoplastic resin)
Extension tube 5 is made up of the thermoplastic resin containing above-mentioned carbon fibre.Saying of above-mentioned carbon fibre

Known arbitrary thermoplastic resin (ABS (acrylonitrile-butadiene-styrene (ABS)) resin such as mentioned above
Deng), as long as it is then arbitrary that its physical property possesses the function as extension tube.But, prolong as shaping
The thermoplastic resin of long tube 5, according to manufacture light-duty and cheap, easy and the viewpoint of process, as at above-mentioned tool
As illustrated by style, polypropylene is preferably used.It addition, thermoplastic resin is not individually to make
By one, it is also possible to arbitrary ratio and be applied in combination two or more.
It addition, extension tube 5 can also be containing any composition beyond above-mentioned carbon fibre and thermoplastic resin.
