At least a portion of this exhaust is imported between the periphery of the interior pipe 69 of tube connector 64 and tube connector 64 via flezxible coupling 111, exhaust outlet 113, through hole 115, then, by and the periphery of the interior pipe 70 of swivelling pipe 67 between, between the interior pipe 77A and outer tube 77B of outer flexible tube 75 and 76 of inner flexible tubes, tube connector 77, the exhaust passage 86 of swan-neck 47 and the 1st breather pipe 88, suck exhaust passage 110, flezxible coupling 111, the bypass 112 of device 57, open 102 directions from exhaust outlet 113 to suction and discharge.The exhaust of this backflow can relax the closed intensity that sucks device 57 and swept surface, alleviates the move operation power that sucks device 57.Simultaneously, the direction that the dust on the swept surface is blowed to suction port 105 is transferred, and utilizes the double effects that rotates with rotating brush 101 to improve dust collecting performance.

Because the structure that telescoping tube 58 adopts is breather pipe 92 to be remained in the exhaust passage 86 of the 1st breather pipe 88 and with exhaust passage 94 sliding freely be communicated with, again breather pipe 93 is remained on sliding freely in the air intake passage 85 of the 1st breather pipe 88 and and be communicated with air intake passage 95, therefore, the shape of guaranteeing air intake passage 95 is not subjected to the influence of exhaust passage 94 shapes, the dust of handover is flowed swimmingly, simultaneously both can guarantee air-tightness, can obtain capable of expansion and contraction again and sliding smoothly.Again, the holding device that use is made of with recess 98, snap fit tabs 99 button 97, engaging, the posture that the user can like with oneself, the length of length adjustment with telescoping tube 58 for ease of cleaning, and kept, in addition, can be when taking in telescoping tube 58 purse ups, the volume that reduces to take in can improve the convenience of use.

Again, owing to be arranged between breather pipe 92 and the breather pipe 93 by a part with holding device, below breather pipe 92, be formed with a plurality of engagings with recess 98, therefore engaging is not exposed on shell, with recess 98, can improve the outward appearance commodity of telescoping tube 58, because engaging is not protruded on air intake passage 95 with recess 98,, both can reduce the ventilation loss again so can pass through the mobile smooth and easy of the interior wind of air intake passage, augmented flow, again can not overslaugh dust flow.

Again,, can make to simplify the structure, reduce the part number, reduce cost because therefore the passage that the exhaust passage 86 of the exhaust passage 94 of breather pipe 92 and the 1st breather pipe 88 is passed through as electric conductor 96, does not need to be provided with specially the electric conductor incorporating section.Again, because electric conductor 96 adopted spiral helicine retractile structure, therefore, but electric conductor 96 root a tree name telescoping tubes 58 is flexible, and brute force can not be applied on the electric conductor 96, can not produce broken string.

In addition, making electric conductor passage, electric conductor by the exhaust passage with present embodiment makes spiral helicine invention and is applied among each embodiment described later helical form be made as electric conductor passage, electric conductor in the exhaust passage, can obtain and above-mentioned same effect, this is self-evident.

Below, with reference to Figure 16 and Figure 17 the 10th embodiment of the present invention is described.The element numeral prosign that all and above-mentioned the 9th embodiment is identical omits its explanation.

As Figure 16 and shown in Figure 17, the 2nd breather pipe 116 is divided into two-layer airway up and down by inwall 117.The inside of the 1st breather pipe 118 has the breather pipe 120 of tubular, and breather pipe 120 is remained near the end of holding pipe 56 sides by the rib 121 from the 1st breather pipe 118.Thus, the other end of breather pipe 120 is the ends that move about, and this moves about in the distolateral airway that is inserted in the 2nd breather pipe 116 tops.The 2nd breather pipe 116 enters the inside of the 1st breather pipe 118, is communicated with and is kept sliding freely by the airtight shapes of sealing gasket 122, constitutes air intake passage 123.Again, breather pipe 120 enters the upper strata passage of the 2nd breather pipe 116, is communicated with and is kept sliding freely by the airtight shapes of sealing gasket 124, constitutes air intake passage 125.

The following describes the effect of said structure.Both can guarantee two venting channels, be separating and air-tightness of air intake passage 123 and exhaust passage 125, can obtain the sliding smoothly of retractile the 2nd breather pipe 116 again.Again, the holding device that employing is made of adjustable ring 126 and seal 129, the posture that the user can like with oneself, the length of length adjustment with telescoping tube for ease of cleaning, and kept, in addition, when taking in body of dust collector, telescoping tube 58 can be shunk, the volume that reduces to take in can improve the convenience of use.

Again, by with lower floor's passage of the 2nd breather pipe 116 as air intake passage 123, downside in the 1st breather pipe 118 forms air intake passage, the dust that the passes through dust that particularly quality is big relies on gravity to slide at telescoping tube inner face downside, for the action that is attracted in the body of dust collector, can reduce being tangled and phenomenon of blocking.

Owing to can constitute two venting channels together by the 2nd breather pipe 116 and the 1st breather pipe 118, therefore, can improve the outward appearance commodity of telescoping tube 58 in the inside of 1 pipe again.

In addition, made telescoping tube 58 explanation, that be provided with available buttons 97 adjusting length among the 9th embodiment, also can obtain same effect certainly if this structure also adopts.

Below, with reference to Figure 18 and Figure 19 the 11st embodiment of the present invention is described.The identical element numeral prosign of all and above-mentioned the 9th or the 10th embodiment omits its explanation.

As Figure 18 and shown in Figure 19, the inside of the 1st breather pipe 130 is provided with narrow tube 131, is bearing near the end of holding pipe 56 sides by the rib 132 from the 1st breather pipe 130, and the other end becomes the end that moves about.The inside of the 2nd breather pipe 133 is provided with narrow tube 134, is remained near the end that sucks device 57 sides by the rib 135 from the 2nd breather pipe 133, and the other end becomes the end that moves about.

The peripheral part of the 2nd breather pipe 133 enters the inside of the 1st breather pipe 130 or the inside that narrow tube 131 enters narrow tube 134, sealing gasket 122 and sealing gasket 124 airtight shapes are communicated with and keep sliding freely by both party, two venting channels that the inboard of formation narrow tube 131 and narrow tube 134 is communicated with the outside, the inboard is made air intake passage 136, the outside is made exhaust passage 137.

The following describes the effect of said structure.Adopt this structure, both can guarantee the separation and the air-tightness of two venting channels, can obtain retractile smooth and easy sliding again.Again,, also can guarantee the area of required exhaust passage 137, in addition, increase the area of air intake passage 136, can guarantee inhalation power, and can guarantee can not tangle the diameter of dust even relatively increase the diameter of narrow tube 134 with respect to the 2nd breather pipe 133.

Again, by narrow tube 134 and narrow tube 131 being configured to only have from the central shaft of the 2nd breather pipe 133 and the 1st breather pipe 130 form of the off-centre of length d, be positioned at the exhaust passage 137 in the narrow tube 134 and narrow tube 131 outsides littler than peripheral part pipe resistance and central portion that flow velocity is fast near, can reduce the ventilation loss, augmented flow.

Again, be placed under the state on the swept surface will sucking device 57, be configured in top position by exhaust passage 137 from air intake passage 136 with telescoping tube 58, can above suction device 57, form exhaust passage 110, exhaust wind is forwards discharged from the exhaust outlet 113 that sucks device 8, this exhaust blows to suction port with the dust on the cleaning face and transfers, can with the double effects of rotating brush 101 rotation under improve dust collecting performance.Again,, can form two venting channels, therefore, can improve the outward appearance commodity of telescoping tube 58 in the inside of 1 pipe owing to the structure that has adopted two bimetallic tube sub-portfolios.

In addition, made telescoping tube 58 explanation, that be provided with available buttons 97 adjusting length among the 9th embodiment, also can obtain same effect certainly if this structure also adopts.And,, also can obtain and above-mentioned same effect certainly adopting narrow tube 134 to enter the occasion of narrow tube 131 structures.

Below, with reference to Figure 20 and Figure 21 the 12nd embodiment of the present invention is described.The identical element numeral prosign of all and above-mentioned the 9th～the 11st embodiment omits its explanation.

As Figure 20 and shown in Figure 21, the inside of the 1st breather pipe 130 is provided with narrow tube 131, is remained near the end of holding pipe 56 sides by the rib 132 from the 1st breather pipe 130, and the other end becomes the end that moves about.The inside of the 2nd breather pipe 133 is provided with narrow tube 134, is bearing near the end that sucks device 57 sides by the rib 135 from the 2nd breather pipe 133, and the other end becomes the end that moves about.The peripheral part of the 2nd breather pipe 133 enters the inside of the 1st breather pipe 130, again, narrow tube 134 enters the inside of narrow tube 131, sealing gasket 122 and sealing gasket 124 airtight shapes are communicated with and keep sliding freely by both party, two venting channels that the inboard of formation narrow tube 131 and narrow tube 134 is communicated with the outside, the inboard is made air intake passage 136, the outside is made exhaust passage 137.

The following describes the effect of said structure.Adopt this structure, when the dust that attracts from suction device 57 is in narrow tube 134 is shifted to narrow tube 131, can not tangled, also can will not attract air-flow to confound in 138 places, can reduce the loss of attraction in the end by the end 97 of narrow tube 131.

Below, with reference to Figure 22 and Figure 23 the 13rd embodiment of the present invention is described.The identical element numeral prosign of all and above-mentioned the 9th～the 12nd embodiment omits its explanation.

As Figure 22 and shown in Figure 23, the 2nd breather pipe 139 enters the inside of the 1st breather pipe 140, is communicated with and maintenance sliding freely by sealing gasket 122 airtight shapes.

In the inside of the 1st breather pipe 140, the narrow tube 141 shorter than the 1st breather pipe 140 length is bearing in by the rib 142 from the 1st breather pipe 140 near the end of holding the pipe side.Again, the inside of the 2nd breather pipe 139 is provided with the narrow tube 143 shorter than the 2nd breather pipe 139 length, is bearing near the end that sucks device 57 sides by the rib 144 from the 2nd breather pipe 139.

Between the inside of the 2nd breather pipe 139 and the 1st breather pipe 140, at least a portion is a corrugated, and be provided with the flezxible coupling 145 that is made of retractile pliability material, is wrapping on the outer peripheral face of narrow tube 141 and narrow tube 143 at the both ends of flezxible coupling 145, and air-tightness connects separately.Adopt this double-sleeve structure, two venting channels 146 that the inboard of formation flezxible coupling 145 is communicated with the outside.

The following describes the effect of said structure.Adopt this structure, both can guarantee the separation and the air-tightness of two venting channels 146, can obtain retractile smooth and easy sliding again.Again, owing to the flezxible coupling 145 in the double-sleeve structure is made of retractile pliability material, therefore, compare with the structure of the slip capable of expansion and contraction that two pitch tubes are made up, can realize lightweight, and can reduce chimeric slide area, the operating physical force in the time of can alleviating telescopic slide.Again, compare, can reduce by 1 sliding part, reduce the sealing gasket that sliding part is used, can reduce cost with the structure of above-mentioned the 11st embodiment.And, owing to adopted double-sleeve structure, therefore, can form two venting channels in the inside of 1 pipe, can improve the outward appearance commodity of telescoping tube 58.

In addition, made telescoping tube 58 explanation, that be provided with available buttons 97 adjusting length among the 9th embodiment, also can obtain same effect certainly if this structure also adopts.

Below, with reference to Figure 24 and Figure 25 the 14th embodiment of the present invention is described.

As shown in figure 24, electric blowing machine 152 is housed in the body of dust collector 151, is formed with the dust storage chamber 153 that the dust that will attract carries out control of dust in the place ahead of electric blowing machine 152.Tube connector 154 is connected in end body of dust collector 151, that have flexual flexible pipe 155 freely and is connected with can adorning to take off, to form the state that is communicated with dust storage chamber 153.The other end of flexible pipe 155 with hold pipe and 156 be connected, manage 156 and be communicated with holding in the dust storage chamber 153 by flexible pipe 155, tube connector 154.Extension 157 can be adorned and take off freely and hold pipe 156 and is connected, and the front end of extension 157 can be adorned to take off freely and be connected with suction device 158.

As shown in figure 25, hold pipe 156 and have the breather pipe 159 of straight tube-like and the handle portion 160 that forms from breather pipe 159 rear branch upward.Handle portion 160 have the portion that extends 161 that is provided with from the top of breather pipe 159 and from the rear of the portion of extending 161 to the handle part 162 of the curved one-tenth of flexible pipe 155 lateral bendings.Extending portion 161 and handle part 162 both can be one-body molded with breather pipe 159, also handle part 162 bodies can be installed on the breather pipe 159 as monomer.Extending portion 161 and handle part 162 and breather pipe 159 when one-body molded, in the metal pattern configuration aspects, the top that extends portion 161 and handle part 162 is provided with peristome, and this peristome is sealed by lid 163.Extend portion 161 above be the inclined plane, on this inclined plane, be provided with operating portion.On operating portion, be furnished with and set operating portion that the electric blowing machine running stops etc.

In the portion of extending 161, be furnished with part that operating portion uses, as the substrate 164 of switch etc. is housed, the operating portion of switch is towards the top peristome of the portion of extending 161, by the operating portion of lid 163 that the top opening is closed, can operate the operating portion of the switch of substrate 164.In the rear end of breather pipe 159, form the hose transition 165 that is connected with flexible pipe 155, flexible pipe 155 is wrapping this hose transition 165.And an end of the flexible pipe 155 that is connected with hose transition 165 is covered by the flexible pipe lid 166 of tubular.Again, the conductor wire 155a that is located on the flexible pipe 155 is electrically connected with the conductor wire 167 that is connected near the substrate 164 the hose transition 165, and conductor wire 167 is derived to hose transition 165 sides by the space that is formed between flexible pipe lid 166 and breather pipe 159 rearward end.

On the front side (with the side that is connected of extension 157) of breather pipe 159 and rear side (with the side that is connected of flexible pipe 155), the tubular axis heart A in relative the place ahead, axle center of this pipe, the tubular axis heart B that forms the rear be (swept surface side) form of deviation a only downwards.As mentioned above, when handle part 162 holds handle part 162 one of the 155 lateral bending Qu Bingyong of direction flexible pipe from hose transition 165, formed the lower position that the flexible pipe 155 that is not covered by flexible pipe lid 166 is in this hand.

And as shown in figure 24, when holding handle part 162 on the height and position of the about 80cm of swept surface, handle part 162 forms the form that upwards leans forward, and is exactly the most easy-to-use calibrated altitude of user from the height and position of the about 80cm of swept surface.

The following describes the effect of said structure.Form straight tube-like owing to hold the breather pipe 159 of pipe 156, therefore, when metal pattern is made,, can reduce the metal pattern expense, can provide cost low product as long as fuse is made linearity.Because of there not being bend,, can highly guarantee inhalation power so shown in the arrow of Figure 25, air-breathing is mobile smooth and easy again.

In addition, using extension 157 and swept surface almost parallel, be approximate horizontal ground can make the suction device of extension 157 tilting actions the time, also can with extension 157 tilting actions to the position of swept surface almost parallel.That is to say that the pipe of holding that will be connected with the other end of extension 157 156 is held, in case this is held pipe 156 near swept surface, then extension 157 along with the tilting action of tube connector to swept surface near and topple over.And, even extension 157 tilting actions arrive the position with the swept surface almost parallel, because holding pipe 156 breather pipe 159 is straight tube-like, therefore, also can prevent to hold pipe 156 breather pipe 159 the bottom with the position of swept surface almost parallel on the phenomenon of colliding with swept surface takes place.

Again, because the rear side of breather pipe 159 deflection below (swept surface side), therefore, can make flexible pipe 155 skews in the swept surface side, the part that utilization moves to the swept surface lateral deviation, bulldozing operation not only can be improved in the angle of inclination (angle of inclination in the axle center of handle part 162 relative breather pipes 159) that can increase handle part 162, even increased the angle of inclination of handle part 162, can prevent that also the hand of holding handle part 162 from contacting with flexible pipe 155.Again,, can utilize the part of skew, the peak of handle part 162 is descended to the swept surface side, can alleviate the weight sense of holding pipe 156 integral body when the identical occasion in the angle of inclination of handle part 162.

And, because the flexible pipe 155 that is not covered by flexible pipe lid 166 is in the lower position of the hand of holding handle part 162, therefore in use, utilize gravity to make flexible pipe 155 hang down to swept surface, increased the gap between handle part 162 and the flexible pipe 155, even the handle part of setting 162 is less with the interval of flexible pipe 155, hand can not contact with flexible pipe 155 yet, can not influence to grip sense.Again, even because of the direction that change to suck device 158 etc. is being carried out the swinging during operation of handle part 162 and since the oscillation center of flexible pipe 155 be in handle part 162 roughly under the position, therefore, also can reduce the amplitude of fluctuation of flexible pipe 155, can improve the use comfort.

And, when on the height and position of about 80cm, holding handle part 162, owing to be provided with angle θ shown in Figure 24, handle part 162 forms and upwarps shape forward, therefore, even when using straight pipe type to hold pipe, wrist also makes progress for 162 cun holding handle part, easily extension 157 is forwards released.

Below, with reference to Figure 26 the 15th embodiment of the present invention is described.The element numeral prosign that all and above-mentioned the 14th embodiment is identical omits its explanation.

As shown in figure 26, be formed with air intake passage 169 and exhaust passage 170 on the breather pipe 168 of the straight tube-like of holding pipe 156, the front side of breather pipe 168 (extension side) is divided into bilevel structure with dividing plate 171 with air intake passage 169 and exhaust passage 170.The rear side of breather pipe 168 (flexible pipe 155 sides) is connected with the flexible pipe 174 that reaches the dual structure that constitutes with the inner flexible tube 173 of its internal communication by outer flexible tube 172.

Below flexible pipe 174 is explained with the structure that breather pipe 168 is connected.Be formed with the inner flexible tube connecting portion 175 of minor diameter and the outer flexible tube connecting portion 176 bigger than inner flexible tube connecting portion 175 diameters, the rear side of inner flexible tube connecting portion 175 is tubuloses, the shape variable of front side can be chimeric with the exhaust passage 170 of the lower layer side of being distinguished by the dividing plate 171 of breather pipe 168.Again, the rear side of outer flexible tube connecting portion 176 is tubuloses, the shape variable of front side, can be chimeric with the air intake passage 169 of the upper layer side of distinguishing by the dividing plate 171 of breather pipe 168, these inner flexible tube connecting portions 175 and outer flexible tube connecting portion 176 have constituted to adorn and take off the flexible pipe dress that is installed in breather pipe 168 rears freely and take off portion 177.Again, inner flexible tube connecting portion 175 is rearward outstanding from outer flexible tube connecting portion 176, is convenient to inner flexible tube 173 is connected with inner flexible tube connecting portion 175.Outer flexible tube connecting portion 176 is connected with outer flexible tube 172, and the front end that is attached to the conductor wire 172a on the outer flexible tube 172 is equipped with plug-in unit 178, can adorn take off freely with the conductor wire 167 that is located at substrate 164 on plug-in unit 178 be electrically connected.

Again, be formed with junction surface 179, engage the front end of corresponding flexible pipe mounting or dismounting portion of portion 179 177, be provided with engaging claw 180, formed and held the detachable form of pipe 156 and flexible pipe 155 in the rear end of holding pipe 156 breather pipe 168.In addition, outer periderm soft tube cap 166 of flexible pipe mounting or dismounting portion 177 covers, in flexible pipe lid 166, be equipped with the plug-in unit 178 of conductor wire 172a, flexible pipe mounting or dismounting portion 177 is in case deviate from from breather pipe 168, then the plug-in unit 178 of conductor wire 172a is also deviate from flexible pipe lid 166, also can install and remove being electrically connected freely.

Again, in order to make the dust catcher of the exhaust of electric blowing machine 152 being sent into the exhaust cycle formula that sucks device 152 sides, as mentioned above, adopted the dual structure that flexible pipe 174 can be constituted air intake passage 169 and exhaust passage 170, hold pipe 156 and constitute air intake passage and exhaust passage too, simultaneously on body of dust collector 151, also need the exhaust passage that the exhaust of electric blowing machine 152 is imported the hose transition side, extension 157 is except air intake passage, also need the structure of exhaust passage, manage 156 structures if adopt holding of present embodiment, the dividing plate that then will distinguish up and down in the extension 157 extends vertically, to constitute bilevel air intake passage and exhaust passage.

The following describes the effect of said structure.Having formed straight tube-like owing to hold the two-layer passage of pipe 156 breather pipe 168, therefore, needed only when metal pattern is made fuse is made linearity, is that the occasion of swan-neck is compared with breather pipe, can reduce the metal pattern expense, can provide cost low product.Again, consider the usability of holding pipe 156, can not be excessively big owing to hold the breather pipe 168 of pipe 156, therefore, the size of air intake passage 169 also is restricted.

The result produces the phenomenon that dust is built up sometimes in air intake passage 169, but because of breather pipe 168 is straight tubes, so can when blocking, can easily thin barred body be inserted and release by observing the accumulation of confirming dust.Consider the dust blockage problem, even the size of breather pipe 168 is amplified to a certain degree, owing to above breather pipe 168, be formed with handle portion 160, therefore, handle part 162 be not subjected to breather pipe 168 sizes about, can guarantee to grip easily the diameter of size like that.Again, dust flows in air intake passage 169, but because what carry out in exhaust passage 170 is exhaust from the electric blowing machine that does not contain dust 152 after the trap debris, therefore, for the exhaust passage 170 that need not consider the dust blockage problem, also can make the sectional area of its sectional area less than air intake passage 169, stop up this problem if pay attention to suppressing dust during design, also the air intake passage 169 and the exhaust passage 170 of present embodiment can be formed interconvertible structure, make heavy dust flow to the air intake passage 169 of below, its sectional area is also increased.

In addition, the dividing plate 170 of air intake passage 169 and exhaust passage 170 both can be separated up and down, separated about also can carrying out, and also can form the concentric circles tubular is dual tube passage.Again, if air intake passage 169 and exhaust passage 170 all are configured in the breather pipe 168, then allocation position also about, about or inside and outside configuration.

Again, because it is detachable with flexible pipe 174 to hold pipe 156, even in air intake passage 169, produced the dust obstruction, also can be by flexible pipe 174 is taken out from hold pipe 156, stretch in the air intake passage 169 that inserts the straight tube-like hold pipe 156 or the straight flexible pipe 155 with thin barred body, can solve the dust blocking problem more easily.In addition,, also can adopt the structure that on the pipe 156 engaging claw 180 is set and junction surface 179 this combinations are set holding on flexible pipe 174, just can hold the mounting or dismounting of pipe 156 and flexible pipe 174 as the mounting or dismounting structure of flexible pipe 174.

Below, with reference to Figure 27～Figure 33 the 16th embodiment of the present invention is described.

As shown in figure 27, dress electric blowing machine 182 in the body of dust collector 181, the connector 183 of this body of dust collector 181 is connected with the tube connector 185 that is connected in flexible pipe 184 1 ends.Connect the extension 188 that sucks device 187 and be connected with tube connector 186, tube connector 186 is connected with flexible pipe 184 other ends.

As Figure 28 and shown in Figure 30, on tube connector 185, dispose body connecting portion 198 that the cross section is roughly double-sleeve structure, be held in clamp 200 on body connecting portion 198 and the lid 199 on the outer circumferential side of this body connecting portion 198, be configured in the swivelling pipe 201 that cross section between body connecting portion 198 and the flexible pipe 184 is roughly dual structure.Apply elastic force with spring 202 to clamp 200, tube connector 185 mounting or dismounting are engaged with connector 183 freely.Swivelling pipe 201 can rotate freely around the axle of tube connector 185 length directions, prevents flexible pipe 184 distortions in the process of using body of dust collector 181.

Be communicated with sealing gasket 205 air-tightness with the interior pipe 204 of swivelling pipe 201 is interior in the interior pipe 203 of body connecting portion 198, the outer peripheral face of the outer peripheral face of interior pipe 203 and interior pipe 204 also air-tightness is communicated with.On the body connecting portion 198 of the outer circumferential side of swivelling pipe 201, fixing fore-and-aft direction fixed contact arranged side by side 206.Fixed contact 206 be electrically connected to the side-prominent splicing ear (not shown) of the body of dust collector 181 of body connecting portion 198.This splicing ear is electrically connected with the body plug-in unit (not shown) that is configured on the body of dust collector 181 with under body connecting portion 198 and the state that connector 183 is connected.

In the inboard of fixed contact 206, with fixed contact 206 subtend shapes dispose the track terminal 207 of similar number, these track terminals 207 are maintained on the railroad shoe 208 of tubular roughly.This railroad shoe 208 is fixed on the outer circumferential side of swivelling pipe 201, in case swivelling pipe 201 around the axle rotation of tube connector 185 length directions, then with swivelling pipe 201 rotations, is remaining being electrically connected of fixed contact 206 and track terminal 207.

The inner flexible tube 192 that forms flexible pipe 184 is wrapping on the interior pipe 204 of swivelling pipe 201, and again, outer flexible tube 191 is wrapping on the outer peripheral face of swivelling pipe 201, and airtight separately shape connects.Wherein, the interior pipe 204 of swivelling pipe 201 is outstanding from the outer peripheral face of swivelling pipe 201.

Again, as described later, the other end of flexible pipe 184 with hold pipe and 186 be connected, inner flexible tube 192 is wrapping holding and is managing on 186 the interior pipe 209 (with reference to Figure 28 or Figure 31), outer flexible tube 191 is wrapping on the outer tube 210 of holding pipe 186, and the interior pipe 209 of holding pipe 186 is axially outstanding from outer tube 210.

Hold pipe 186 as Figure 28 and shown in Figure 31, have: the cross section of interior pipe 209 that inner flexible tube 192 is being wrapped and outer tube 210 that outer flexible tube 191 is being wrapped is roughly the tube connector 211 of double-sleeve structure; With the portion of wrapping the place ahead of flexible pipe 184 accommodate, the front side general curved becomes ㄑ word shape and the swan-neck 212 that can be connected freely with extension 188 mounting or dismounting at leading section; Be configured in the switch substrate 214 in the member storage portion 213 of bend top of swan-neck 212; Operate the operating portion 215 of this switch substrate 214; Above the rear of operating portion 215 and swan-neck 212, be arranged to handshake part (being equivalent to be located at the handshake part of holding on the pipe) 215a of branch-like; The lid 216 and of holding a writing brush or pen-write that the top opening of swan-neck 212 is covered swingably by the clamp 217 that is held a writing brush or pen-write lid 216 and swan-neck 212 clampings and can engage freely with extension 188 mounting or dismounting.

Swan-neck 212 is divided into bilevel passage by inwall 218, and air intake passage 189 is communicated with the interior pipe 209 airtight shapes of tube connector 211, and exhaust passage 190 airtight shapes are communicated in the interior pipe 209 of tube connector 211 and the passage between the outer tube 210.

Conductor wire 219 is with after track terminal 207 is connected, from wrapping between the portion of outer flexible tube 191 and swivelling pipe 201 outer peripheral faces, be imported into the exhaust passage 190 of 192 of outer flexible tube 191 and inner flexible tubes, another is distolateral from the wrapping portion derivation of outer flexible tube 191 with the outer tube 210 and the outer flexible tube 191 of tube connector 211.Be connected with switch substrate 214 through member storage portion 213 backs.In the present embodiment, conductor wire 219 helical forms are installed on the inner peripheral surface of outer flexible tube 191.In addition, be provided with the structure of conductor wire 219 in the exhaust passage 190 of the exhaust flow by making the cleaning after removing dust, then dust can not contact with conductor wire 219, can make for dustproof and simplifications such as coating processing protection conductor wire 219.In addition, in exhaust, include the carbon dust that produces from electric blowing machine 182.

Shown in figure 32, the structure of extension 188 is slidably freely narrow tube 221 to be remained in the large-diameter pipe 220, this large-diameter pipe 220 is detachable to engage detachable tube connector 222 engagings that will suck device 187 freely of the front end of narrow tube 221 freely with swan-neck 212.

Large-diameter pipe 220 is divided into bilevel airway, is air intake passage 189 and exhaust passage 90 by inwall 223.Narrow tube 221 has: air intake duct 224; Be fixed on the air intake duct lid 225 on the air intake duct 224 from the top of air intake duct 224; And be housed in by air intake duct 224 and air intake duct lid 225 and distinguish the interior pair of conductive line 227 of the receiving room that forms 226.The two ends of this conductor wire 227 are connected with splicing ear (not shown), with extension 188 with hold pipe 186 and suck device 187 when being connected, form and be located at the state that the splicing ear (not shown) on pipe 186 and the suction device 187 is electrically connected of holding.Conductor wire 227 in the large-diameter pipe 220 is by insulation tube 228 protections.

Blast pipe 229 slidably remains in the exhaust passage 190 of large-diameter pipe 220 freely, is communicated with exhaust passage 190.The leading section of blast pipe 229 is fixed on the lower cover 230, and this lower cover 230 is fixed on the air intake duct 224 of narrow tube 221 from its below, exhaust passage 190 that is formed by lower cover 230 and air intake duct 224 and 229 interior connections of blast pipe.

Suck device 187 as shown in figure 33, in the place ahead that sucks device 187, rotation is keeping the rotating brush 232 of built-in motor 231 freely.Rotating brush 232 is driven by motor 231 rotations of interior dress, transmits rotation by deceleration device (not shown), is rotated with about 1500 rotating speeds of per minute.Rotating brush 232 is in the face of being located at following suction inlet 233, and a plurality of fins 234,235 that are provided with along side face will be attached to the dust on the cleaning face etc. and kick up.

Suction port 236 is formed on the rear of rotating brush 232, is communicated with but face upward the connecting cylinder 237 of bowing freely with above-below direction.Suck certain angle, the rotation that device pipe 238 can left and right directions and is connected two passes about dividing into by tube wall 239 freely with connecting cylinder 237.The place ahead of the air intake passage 189 of top is communicated with aforesaid connecting cylinder 237, and the rear is communicated with the narrow tube 221 of extension 188.The rear of the exhaust passage 190 of below is communicated with the exhaust passage 190 of extension 188, and the place ahead is communicated with from the front portion to the exhaust outlet 242 that suction inlet 233 is discharged with the exhaust of being discharged by electric blowing machine 182 runnings then by flezxible coupling 240, bypass 241.

The following describes the action of said structure.186 operating portion 215 makes electric blowing machine 182 runnings in case operator holds a writing brush or pen-write, and meanwhile, makes rotating brush 232 rotations that driven by motor 231 rotations, is kicked up by the dust that fin 234,235 will be positioned on the swept surface.

The dust of being kicked up by fin 234,235 is by the inspiratory flow that attraction produced of electric blowing machine 182, is transferred in the dust storage chamber 193 via extension 188, flexible pipe 184, the air intake passage 189 that is located on the body of dust collector 181 from suction inlet 233, builds up there.The inspiratory flow of the cleaning of separating with dust is discharged in the anti-cylinder record 194 by behind the electric blowing machine 182.

At least a portion of the exhaust of discharging in anti-cylinder record 194 is via blast pipe 195, exhaust introducing port 197, again by flexible pipe 184, extension 188, be located at the exhaust passage 190 that sucks on the device 187, from exhaust outlet 242 to suction inlet 233 discharges.The exhaust of this backflow can relax the closed intensity that sucks device 187 and cleaning face, alleviates the move operation power that sucks device 187.Simultaneously, the dust on the cleaning face is blowed to suction port 236 transfer, utilize the double effects that rotates with rotating brush 232 to improve dust collecting performance.

Because the structure of flexible pipe 184 is inner flexible tubes 192 that configuration forms air intake passage 189 in flexual outer flexible tube 191, the space that is formed between outer flexible tube 191 and the inner flexible tube 192 is made exhaust passage 190, the both ends of outer flexible tube 191 and inner flexible tube 192 are fixed on tube connector 185 and hold on the pipe 186, therefore, except being fixed on tube connector 185 and holding the both ends of managing on 186, the situation of outer peripheral face root a tree name flexible pipe 184 bendings of the inner peripheral surface of outer flexible tube 191 and inner flexible tube 192 etc. freely contacts, pars intermedia at flexible pipe 184, inner flexible tube 192 moves freely in outer flexible tube 191, crooked easily on all directions, the bendability of flexible pipe 184 and retracting property can be improved, the convenience of use can be improved.

No matter how the inner peripheral surface of outer flexible tube 191 contacts with the outer peripheral face of inner flexible tube 192, and being formed at outer flexible tube 191 is identical with exhaust passage 190 sectional areas between the inner flexible tube 192.On the other hand, because of outer flexible tube 191 has pliability, so near the aeration resistance the inner peripheral surface of outer flexible tube 191 is big.When outer flexible tube 191 contacts with inner flexible tube 192, the circumferencial direction distance of outer peripheral face and the inner peripheral surface of outer flexible tube 191 that forms the inner flexible tube 192 of exhaust passage 190 becomes maximum, and it is little that the aeration resistance of exhaust passage 190 at this moment is in coaxial occasion than outer flexible tube 191 and inner flexible tube 192.

Secondly, air intake passage 189 is formed by inner flexible tube 192.When the cross-wise direction of inner flexible tube 192 was seen, if the girth lengthening, it is big that the aeration resistance of air intake passage 189 just becomes, but as previously mentioned, because of air intake passage 189 will be made in the inner flexible tube 192,, can reduce aeration resistance so can obtain maximum aisle spare with the girth of minimum, again, as mentioned above, because of the aeration resistance of exhaust passage 190 is little, so can increase air-breathing air quantity and exhaust air quantity, dust collecting performance can be improved, the convenience of use can be improved.

Again, because wrapping the interior pipe 204 of the swivelling pipe 201 of inner flexible tube 192 gives prominence to from the outer peripheral face of swivelling pipe 201, the interior pipe 209 of holding pipe 186 is outstanding from outer tube 210, therefore, after inner flexible tube 192 is connected, by outer flexible tube 191 is connected, can be easily with flexible pipe 184 with tube connector 185 or hold and manage 186 and be connected, can improve the productivity of flexible pipe 184.

Again, because in holding pipe 186, the air intake passage 189 that has formed flexible pipe 184 and exhaust passage 190, the air intake passage 189 and the exhaust passage 190 that are connected with exhaust passage 190 with the air intake passage 189 of extension 188 respectively, therefore, can form easily from sucking device 187 to air intake passage 189 between the body of dust collector 181 and exhaust passage 190, and, can between dual flexible pipe and two-layer extension, be connected air intake passage 189 and exhaust passage 190 simultaneously, can improve the convenience of use.

Because extension 188 is two-layer extensions that the air intake passage 189 that will form on top and the exhaust passage 190 that forms in the bottom are set up in parallel, therefore, can make holding of being connected with extension 188 manage 186 simplify the structure again.

Again, because the sectional area of the sectional area ratio exhaust passage 190 of air intake passage 189 is big, therefore, need not change the external diameter of outer flexible tube 191, the sectional area of the air intake passage 189 when not being provided with exhaust passage 190 is compared, can correspondingly reduce the sectional area of air intake passage 189, under the situation that can not reduce pumping property significantly, exhaust be blowed to the air entry 233 that sucks device 187, can improve dust collecting performance.

Again,, therefore, can in flexible pipe 184, dispose conductor wire 219 easily, can reduce cost owing on the exhaust passage 190 of flexible pipe 184, disposed conductor wire.

In addition, in the present embodiment, extension 188 is two-layer extensions that air intake passage 189 that will form on top and the exhaust passage 190 that forms in the bottom are set up in parallel, but also can in air intake passage 189, connect the structure that dual extension is made in exhaust passage 190, in this occasion, also can form easily from sucking device 187 to air intake passage 189 between the body of dust collector 181 and exhaust passage 190, and, can be between dual flexible pipe and two-layer extension, connect air intake passage 189 and exhaust passage 190 simultaneously, can improve the convenience of use.

Again, conductor wire 219 by helical form around twist on the outer flexible tube 191 and import outer flexible tube 191 and inner flexible tube 192 between exhaust passage 190, but also can in exhaust passage 12, be configured to roughly linearity, in this occasion, can shorten conductor wire 219 and length, can reduce cost.

Below, with reference to Figure 34～Figure 37 the 17th embodiment of the present invention is described.

As shown in figure 34, dress electric blowing machine 152 in the body of dust collector 151, the connector 153 of this body of dust collector 151 is connected with the tube connector with splicing ear 155a 155 that is connected in flexible pipe 154 1 ends.Flexible pipe 154 other ends are connected with extension 158, and this extension 158 will suck device 157 and be connected with the pipe 156 of holding of the operating portion 156b with the switch substrate 156a that takes in electric blowing machine 152 running controls.Air intake passage 159 be one from sucking the passage of the inspiratory flow that device 157 attracts by electric blowing machine 152 via extension 158, flexible pipe 154, connect to be located at the form that sucks on device 157, extension 158, flexible pipe 144, the body of dust collector 151 and make an air intake passage respectively.Exhaust passage 160 is exhausts of being undertaken by electric blowing machine 152 from body of dust collector 151 via flexible pipe 154, extension 158 to sucking the passage that device 157 flows, and connects with the form that is located at body of dust collector 151, flexible pipe 154, extension 158 respectively, sucks on the device 157 and makes an exhaust passage 160.

As Figure 35 and shown in Figure 36, the structure of flexible pipe 154 is, in flexual outer flexible tube (preferably paying attention to the undulatory flexual flexible pipe of having of bendability) 161, set the flexual inner flexible tube 162 that forms air intake passage 159 across this outer flexible tube 161 and inner face, the space that will form between outer flexible tube 161 and inner flexible tube 162 is as exhaust passage 160, with the both ends of outer flexible tube 161 and inner flexible tube 162 be located on the tube connector 155 outer tube 163 and in pipe 164, be located at the outer tube 163a that holds on the pipe 156 and in pipe 164b be connected and fixed.Outer flexible tube 161 and inner flexible tube 162 have with the regulation the spacing helical coil around line feeder 165, simultaneously on the periphery of inner flexible tube 162, with greater than the spacing helically of the line feeder 165 of outer flexible tube 161 with many conductor wires 166 be configured in line feeder 165 near.Derive from the connecting portion of outer flexible tube 161 end of conductor wire 166, is electrically connected with being located at the splicing ear 155a that holds the switch substrate 156a on the pipe 156 and be located on the tube connector 155, and switch substrate 156a and electric blowing machine 152 are electrically connected.

In addition, as shown in figure 37, even on the interior week that the line feeder 165 and the conductor wire 166 of outer flexible tube 162 is configured in inner flexible tube 162, also can obtain same effect certainly.

The following describes the effect of said structure.On the periphery owing to the inner flexible tube 162 that conductor wire 166 is configured in all length, than the winding diameter (Japanese: coil diameter) little that disposes the conductor wire 166 on the flexible pipe 161 outside, therefore, can reduce the use amount of conductor wire 166, again, because the line feeder spacing of the gap ratio outer flexible tube 161 of conductor wire 166 is big, therefore, can further reduce the use amount of conductor wire 166, can alleviate flexible pipe 154 weight, can improve operability.

Below, with reference to Figure 38 and Figure 39 the 18th embodiment of the present invention is described.The element numeral prosign that all and above-mentioned the 17th embodiment is identical omits its explanation.

As Figure 38 and shown in Figure 39, outer flexible tube 161 is provided with line feeder 165 on the interior week of flexible pipe tape 167, with distortion and the breakage that prevents flexible pipe 154, guarantees shape invariance.Inner flexible tube 162 is that the conductor wires 166 that will pass through a large amount of insulation coating 168 processing are configured on the interior week of flexible pipe tape 167a with the interval helically of stipulating.

The following describes the effect of said structure.Coat 168 processing owing on conductor wire 166, passed through insulation, add and be furnished with line feeder, but therefore weight reduction.In addition, present embodiment is that line feeder 165, conductor wire 166 were configured on the interior week of flexible pipe tape 167,167a, but also configurable on the periphery of flexible pipe tape 167,167a, also can obtain same effect certainly.

Below, with reference to Figure 40 and Figure 41 the 19th embodiment of the present invention is described.The element numeral prosign that all and above-mentioned the 18th embodiment is identical omits its explanation.

As Figure 40 and shown in Figure 41, the structure of inner flexible tube 162 is the length directions along the outside flexible pipe of flexible pipe tape 167a, configuration nylon wire, cotton thread, the line feeder 169 that is made of other material coat 168 hard wires of handling 170 through insulation and carry out bonding or welding is fixed a plurality of with the interval helically of regulation simultaneously.

The following describes the effect of said structure.Owing to hard wire 170 as conductor wire and line feeder, therefore, can be strengthened the line feeder spacing, reduce the use amount of hard wire 170.Again, owing to can utilize line feeder 169 to prevent the caused elongation of the tension force that puts on flexible pipe 154 that retracts etc. because of the body of dust collector 151 in the cleaning or the phenomenon of disconnection, therefore, but the thickness of attenuate flexible pipe tape 167,167a, but weight reduction.Owing to the outside that line feeder 169 is configured in inner flexible tube 162 is on the exhaust passage 160, therefore, do not worry the phenomenon that dust is tangled to occur again.Again, even the portion that is provided with inner flexible tube 162, the outer flexible tube 161 of line feeder 169 also can obtain same effect certainly.

Below, with reference to Figure 42 and Figure 43 the 20th embodiment of the present invention is described.The element numeral prosign that all and above-mentioned the 17th embodiment is identical omits its explanation.

As Figure 42 and shown in Figure 43, flexible pipe 154 has flexual outer flexible tube 161 and inner flexible tube 162 constitutes by undulatory, air intake passage 159 will be made in the inner flexible tube 162, to make exhaust passage 160 between outer flexible tube 161 and the inner flexible tube 162, the both ends of outer flexible tube 161 and inner flexible tube 162 be located on the tube connector 155 outer tube 163 and in the outer tube 163a that holds on the pipe 156 of pipe 164 and being located at and in pipe 164b be connected and fixed.On the interior week of the flexible pipe tape 167 of outer flexible tube 161, helically disposes a plurality of hard wires 170 that coat 168 processing through insulation, derive from the connecting portion of outer flexible tube 161 end of hard wire 170, be electrically connected with being located at the splicing ear 155a that holds the switch substrate 156a on the pipe 156 and be located on the tube connector 155, switch substrate 156a and electric blowing machine 152 are electrically connected.And the interior external diameter of inner flexible tube 162 poor (t1) is less than the interior external diameter of outer flexible tube 161 poor (t2).

The following describes the effect of said structure.The conductor wire that employing is located on the outer flexible tube 161 is a hard wire 170, can guarantee the intensity of flexible pipe 154, and, after inner flexible tube 162, outer flexible tube 161 are connected, need not consider to be located at conductor wire on the outer flexible tube 161 retract and conductor wire retracts the problems such as air-tightness of portion, can easily carry out and hold being electrically connected of pipe 156 and tube connector 155.Again,, therefore, make air-breathing area identical, can reduce the external diameter of outer flexible tube 161, can promote the lightweight of flexible pipe 154 with leaving area because it is poor to have dwindled the interior external diameter of inner flexible tube 162.Again, if outer flexible tube 161 external diameters are identical, then can increase leaving area, air-breathing area, can reduce air-breathingly, the pressure loss of exhaust, its effect are to be difficult to produce dust obstruction etc. in flexible pipe 154.

In addition, present embodiment be the flexible pipe with dust catcher to be used for channel design air-breathing, exhaust be that example explains, but flexible pipe of the present invention is not limited only to gas, also can utilize air and steam or aqueous fluid.

The 1st breather pipe 208 by inwall 211 divide into up and down two-layer airway promptly, exhaust passage 212 and air intake passage 213.The 2nd breather pipe 209 separates breather pipe 214 with breather pipe 215, breather pipe 214 constitutes exhaust passage 216, and breather pipe 215 constitutes air intake passage 217.That is to say that breather pipe 214 and breather pipe 215 are to be axially arranged with the state configuration in gap, distolateral can an insertion sliding freely vertically in the exhaust passage 213 of the 1st breather pipe 208 of breather pipe 214 is connected with exhaust passage 213.Again, distolateral can an insertion sliding freely vertically in the air intake passage 212 of the 1st breather pipe 208 of breather pipe 215 is connected with air intake passage 212.

Electric conductor 218 is housed in the exhaust passage 212 of stretching pipe lid 219 formed receiving rooms 220 and the 1st breather pipe 208 by breather pipe 215 with from upper fixed in the leisure of this breather pipe 215.The two ends of this electric conductor 218 are connected with splicing ear (not shown), in that the other end forms and is located at the state that pipe 175 and splicing ear (not shown) on the suction device 176 are electrically connected of holding with after suction device 176 is connected with holding pipe 175 with an end of telescoping tube 177.In addition, electric conductor coats 221 with its surface protection with insulation.

Button 222 has the snap fit tabs 223 that moves up and down with operating interlock up and down, below breather pipe 215 promptly, with the face of breather pipe 214 subtends on, be formed with a plurality of engagings vertically with recesses 224 with predetermined distance, snap fit tabs 223 engages with this at the interstitial site place of 215 of breather pipe 214 and breather pipes and connects shape with recess 224 bullets and engage.Utilize this snap fit tabs 223 and engaging with recess 224, the overhang of the 2nd breather pipe 209 relative the 1st breather pipes 208 can be adjusted to the dust catcher user and feel suitable length.In addition, extension 177 forms identical separately shape with the connecting portion 51 of holding pipe 175 connecting portion shape and sucking device 176 and extension 177, can be directly with use after sucking device 176 and holding pipe 175 and is connected.

As shown in figure 49, in the place ahead that sucks device 176, the rotating brush 1226 of motor 225 in keeping freely, is housed in rotation.Rotating brush 226 is driven by motor 225 rotations of interior dress, transmits rotation by deceleration device (not shown), with the about 1500 rotating speeds rotation of per minute.Rotating brush 226 is in the face of being located at following suction opening 227, kicks up by the dust that a plurality of fin 228, brush 229 will be attached on the swept surface is housed along side face.Suction port 230 is formed on the rear of rotating brush 226, is communicated with but face upward the connecting cylinder 231 of bowing freely with above-below direction.Sucking device pipe 232 can be connected with connecting cylinder 231 freely along left and right directions, rotation at a certain angle, divides into two passes up and down by tube wall 233.The place ahead of the air intake passage 234 of top is communicated with aforesaid connecting cylinder 231, the rear is communicated with the air intake passage 217 of extension 177, the rear of the exhaust passage 235 of below is communicated with the exhaust passage 216 of extension 177, and the place ahead and flezxible coupling 236, cover the anterior bypass (exhaust passage) 237 that forms from the top that sucks device 176 and be communicated with, be formed with exhaust outlet 238 in the terminal of bypass 237.And, will discharge to suction opening 227 directions from the exhaust outlet 238 of bypass 237 by the exhaust that electric blowing machine 178 runnings are discharged.

In addition, the sectional area of described each exhaust passage is about about 70% of the air intake passage sectional area that sucks device 176, extension 177, flexible pipe 173.

The following describes the action and the effect of said structure.175 operating portion 201 makes electric blowing machine 178 runnings in case operator holds a writing brush or pen-write, and meanwhile, to motor 225 supply capabilities, 225 pairs of rotating brushes 226 of motor are rotated driving by electric conductor 218.At this moment, the fin flat board 228 of rotating brush 226, brush 229 dust that will be positioned on the swept surface is kicked up.

The dust of being kicked up is by the inspiratory flow that attraction produced by electric blowing machine 178, be transferred in the dust storage chamber 179 via suction opening 227, suction port 230, connecting cylinder 231, the air intake passage 205, inner flexible tube 196, the interior pipe 190 of swivelling pipe 187, the interior pipe 189 of tube connector 184 of exhaust passage 212, swan-neck 198 of air intake passage the 217, the 1st breather pipe 208 that suck air intake passage the 234, the 2nd breather pipe 209 of device pipe 232, build up there.The inspiratory flow of the cleaning of separating with dust is discharged in the anti-cylinder record 180 by behind the electric blowing machine 178.

This exhaust is imported between the periphery of the interior pipe 189 of tube connector 184 and tube connector 184 via blast pipe 181, exhaust outlet 183, through hole 236, then, by and the periphery of the interior pipe 190 of swivelling pipe 187 between, between outer flexible tube 195 and the inner flexible tube 196, between the interior pipe 197A and outer tube 197B of connecting portion 197, the exhaust passage 213 of swan-neck 198 and the 1st breather pipe 208, suck exhaust passage 235, flezxible coupling 236, the bypass 237 of device 176, discharge to suction opening 227 directions from exhaust outlet 238.Exhaust after this backflow can relax the closed intensity that sucks device 176 and swept surface, alleviates the move operation power that sucks device 176.Simultaneously, the dust on the swept surface is blowed to suction port 230 transfer, utilize the double effects that rotates with rotating brush 226 to improve dust collecting performance.

Because the exhaust that refluxes to suction device 176 in above-mentioned path is to bend to different shape in the dust catcher use, therefore, be to be placed under the state that bears maximum aeration resistance and be difficult to flow with the flexible pipe 173 as the exhaust passage between outer flexible tube 195 and the inner flexible tube 196.Simultaneously, owing to be again the exhaust passage of closing on most of discharging in the flexible pipe 173 from body of dust collector 171, therefore, be subjected to the influence of the Joule heat that produces by electric blowing machine 178, become the highest exhaust gas heat of temperature, but because outer flexible tube 195 has the pyroconductivity higher than inner flexible tube 196, therefore, inner flexible tube 195 whole length are being diffused exhaust gas heat expeditiously in atmosphere, can prevent the hot deterioration of inner flexible tube 196 and outer flexible tube 195 itself, and the flexible pipe 173 that can bear long-term use can be provided.Because the color of outer flexible tube 195 has adopted the good black of heat emission, therefore, can further improve the effect of radiation exhaust gas heat in atmosphere again.

Again, well-known, every rising 1 degree of gas temperature, volume increases 1/273 approximately.Thus, the tube connector that is distributed in flexible pipe 173 174 of delivery temperature is in the highest, and 176 places are reduced to atmospheric temperature basically at the suction device.Under the condition that this temperature descends, the exhaust air quantity that enters in the exhaust passage of flexible pipe 173 reduces in sucking device 176, because of circulation has influenced the raising of dust suction performance, but owing to utilize flexible pipe 173 to diffuse heat to atmosphere, therefore, also can obtain to reduce the effect of the loss of above-mentioned air quantity.

In addition, present embodiment is to have added metallic fiber such as aluminium in the pliability material of vinyl chloride etc., goes out also other material certainly, perhaps also can not add, even base material itself is formed by the big material of pyroconductivity, also can obtain same effect.

And, the color of outer flexible tube 195 is adopted black, shed to improve heat, even but form without the good color of heat emission, also can fully obtain above-mentioned heat emits effect certainly.

Below, with reference to Figure 50 the 22nd embodiment of the present invention is described.In addition, the structure beyond the outer flexible tube is identical with above-mentioned the 21st embodiment, omits its explanation.

As shown in figure 50, outer flexible tube 195a is rolled into helical form along its length with the fibre sheet material that the synthetic resin of polyester and nylon etc. is made, and is bonding as flexible pipe mutually in superposed part, will encase in the inner flexible tube 196.

Again, the thickness of outer flexible tube 195a is thick in tube connector 174 sides, and it is thin to hold pipe 175 sides.

The following describes the effect of said structure.In this structure, electric blowing machine 178 is in case action, then from the exhaust of electric blowing machine 178 between the periphery of swivelling pipe 187 and interior pipe 190, discharge between outer flexible tube 195a and inner flexible tube 196.Because outer flexible tube 195a forms by fibre sheet material, therefore, the part of this exhaust with exhaust with heat emit to the outside by fibre sheet material.

In this occasion, compare with above-mentioned the 21st embodiment, can obviously improve exhaust with the dispersion effect of heat.Again, the part of exhaust be directly proportional to the part of emitting in the air, can increase from the air-breathing air quantity that sucks device 176, shown in above-mentioned the 21st embodiment, compare with the dust catcher of 100% loop structure, can increase, can improve the dust suction performance from the suction air quantity that sucks device 176.

In addition, though might the noise from flexible pipe 173 be strengthened because of emit a part of exhaust from outer flexible tube 195a, but owing to be from the whole surface discharge of the outer flexible tube 195a of the about 1.4m of total length, therefore, above-mentioned discharge wind speed almost approaches zero, also can not cause noise to strengthen and emits the phenomenon that the ground dust that causes blows afloat because of exhaust.Again, the user of dust catcher can not feel the exhaust wind and the exhaust gas heat of uncomfortable clothes yet.

And, owing to adopt the structure of outer flexible tube 195a, therefore, having strengthened the surface area of outer flexible tube 195a with bag in the inner flexible tube 196, can exhaust be emitted from the big position of surface area, can further disperse exhaust gas heat expeditiously.

Again,, therefore, regulate aeration easily, can easily regulate the exhaust air quantity of emitting from outer flexible tube 195a surface because outer flexible tube 195a is formed by fibre sheet material.And because of the outer tube side of dual structure adopts fibre sheet material, so have high flexibility, the result makes the usability of flexible pipe 173 as a whole very good.

Secondly, the pressure distribution of the exhaust of discharging from electric blowing machine 178 be anti-cylinder record 180 for maximum, form at exhaust outlet 238 places that suck device 176 and to be roughly atmospheric state, therefore, be that emit exhaust at tube connector 174 places of outer flexible tube 195a maximum naturally.And, the thickness of the outer flexible tube 195a of the air intake passage of formation flexible pipe 173 is thick in tube connector 174 sides, it is thin to hold pipe 175 sides, therefore, the distribution that the ventilation crushing loses also is tube connector 174 side height, it is low to hold 175 of pipes, the exhaust of discharging from outer flexible tube 195a can be on the whole length of outer flexible tube 195a homogenising.The result is that the exhaust that circulates from body of dust collector 171 can be directed into extension 177 reliably, suck the smaller exhaust passage of flowing resistance of device 176, can guarantee the capacity with dust suction effect of discharging from exhaust outlet 238.

Below, with reference to Figure 51 and Figure 52 the 23rd embodiment of the present invention is described.

Figure 51 is the electric blowing machine that dust catcher of the present invention uses, and an end opening of anti-load-side support 241, the other end are the roughly cylindric of obturation, are placed with stator 242 and rotor 243 respectively on this anti-load-side support 241.Load-side support 244 is provided on the open end of anti-load-side support 241, with the peristome closure.Be provided with a plurality of exhaust outlets 245 in the side of anti-load-side support 241, be provided with a plurality of cooling vents 246 in the bottom surface, has the cooling fan 248 that directly is connected with the rotating shaft 247 of described rotor 243 and the rotor in the support 243 and stator 242 are cooled off in its outside, face is installed fan cover 249 from it, constitutes motor 250.And, the other end at the rotating shaft 247 of rotor 243, the impeller 251 that produces attraction is installed, the housing 254 of this impeller 251 of interior bag is pressed into anti-load-side support 244, this housing 254 has air entry 252 at central portion, on the periphery circle, have the exhaust outlet 253 that the air-flow that is produced by impeller 251 is emitted, constitute electric blowing machine.In addition, the load-side support 244 of present embodiment is provided in the periphery of impeller 251, also plays a part to adjust the air guiding of air-flow.Cooling air is flowed into by the attraction mouth 249a of cooling fan 248 from inflow entrance (not shown) the process fan cover 249 of body of dust collector 256, and rotor in the support 243 and stator 242 are cooled off.
