In more detail, support 41 is made of the support 41a of supporting the 1st brush portion 21 and the support 41b of supporting the 2nd brush portion 31.Support 41a, 41b can be provided with and the 1st brush portion 21 and the 2nd brush portion 31 corresponding numbers, and therefore, in the present embodiment, 2 support 41a and 2 support 41b are arranged on the revolving body 13.
Support 41 is the groove that forms at the line that point on the side face of revolving body 13, on each circumference of this side face of clamping connects.The 1st brush portion 21 inserts among the support 41a by its base cloth 22b and is directly supported by support 41a.In addition, the 2nd brush portion 31 brushes 32 scraping blade 33 insertion support 41b by the clamping looped pile and is supported by support 41b.
Support 41a, 41b can form along the rotating shaft of revolving body 13 as long as spreading all over the whole zone of its rotor shaft direction along the side face of revolving body 13 forms, and perhaps reverses at the gyratory directions of revolving body 13 to form.
In addition, support 41a, 41b alternately uniformly-spaced is being provided with at the gyratory directions of revolving body 13.Thus, during revolving body 13 revolution, contact with intersecting with floor through each bristle 32a of the looped pile brush 32 of scraping blade 33 supportings by support 41b by each bristle 22a of the broad wool brush 22 of support 41a supporting.As a result, can carry out the scouring of the floor due to the above-mentioned charged and looped pile brush 32 due to the broad wool brush 22 effectively.Thus, support 41 supporting brush portions 12 by the revolution of revolving body 13, make broad wool brush 22 and looped pile brush 32 alternately contact with floor.
Below, the 2nd brush portion 31 is described in detail.
At first, explain scraping blade 33.
Fig. 5 is the cutaway view of the scraping blade 33 when dissecing scraping blade 33 perpendicular to the plane of the rotating shaft of revolving body 13.Scraping blade 33 is by the 1st support 33a, and the 2nd support 33b and the 3rd support 33c constitute.The 1st support 33a and the 2nd support 33b are the member that supporting looped pile brush 32 (with reference to Fig. 1) in clamping, the relative looped pile brush 32 of the 1st support 33a (clip position of looped pile brush 32) is positioned at the gyratory directions upstream side of revolving body 13, and the relative looped pile brush 32 of the 2nd support 33b (clip position of looped pile brush 32) is positioned at the downstream of above-mentioned gyratory directions.
The end of the 1st support 33a and the 2nd support 33b interconnects, and is connected with the 3rd support 33c at this connecting portion.The 3rd support 33c is the member of supporting the 1st support 33a and the 2nd support 33b, and its section becomes roughly along the shape of the inwall of the support 41b of revolving body 13.Thus, the 3rd support 33c can be inserted among the support 41b of revolving body 13, and by insertion like this, scraping blade 33 all can be through support 41b by revolving body 13 supportings.In addition, the 1st support 33a, the 2nd support 33b and the 3rd support 33c have and the corresponding length in whole zone along the formation direction of the support 41b of the side face of revolving body 13.
In addition, the length along the radius of gyration direction of looped pile brush 32 among the 1st support 33a and the 2nd support 33b is set as follows.That is, the 1st support 33a goes up along the length setting of the radius of gyration direction of looped pile brush 32 and becomes the maximum radius of gyration of the 1st support 33a littler than the maximum radius of gyration of the 2nd support 33b.And the 2nd support 33b goes up along the length setting of the radius of gyration direction of looped pile brush 32 and becomes the maximum radius of gyration of the 2nd support 33b littler than the maximum radius of gyration of looped pile brush 32.
By by above-mentioned the former setting, along with the revolution of revolving body 13,32 revolutions of looped pile brush, when the front end of looped pile contacted with floor, the front end of above-mentioned looped pile can stagger to the gyratory directions upstream side of revolving body 13.At this moment, can alleviate the load on the front end that is applied to above-mentioned looped pile, can alleviate its abrasion, improve the durability of looped pile brush 32.In addition, moreover, and keep out of the way to above-mentioned gyratory directions upstream side, increased the contact area of looped pile brush 32, can promote the scouring effect of floor extraordinarily with floor because of the front end of above-mentioned looped pile.
By the above-mentioned latter's setting, when floor for example was smooth floor or tatami, looped pile brush 32 contacted with floor, and scraping blade 33 does not contact with floor.In addition, when floor for example was flannelette blanket, because of the hair of flannelette blanket is high, the flannelette blanket surface contacted with the 2nd support 33b of scraping blade 33, can tap the dust on the flannelette blanket.Therefore, floor is under the flannelette blanket situation in addition, because of the contact of scraping blade 33, can avoid damaging floor.And floor can be cleaned flannelette blanket reliably by scraping blade 33 when being flannelette blanket.
In addition, the surface in the gyratory directions downstream of the revolving body 13 in the mat woven of fine bamboo strips 2 support 33b leading sections (with the end that is connected the side opposition side of the 1st support 33a) becomes and is formed with tiny concavo-convex asperities.During revolving body 13 revolutions, looped pile brush 32 is with before floor (for example flannelette blanket) contacts, the 2nd support 33b that is in the scraping blade 33 in gyratory directions downstream by comparison contacts with floor, but the above-mentioned surface by the mat woven of fine bamboo strips 2 support 33b becomes asperities, dust on the flannelette blanket can be tapped reliably with this surface, the effect of removing of dust can be improved.
Below, there is the looped pile brush 32 of characteristic to describe most to of the present invention.
Looped pile brush 32 is fixed on the base cloth 32b along a direction entirely by the two ends with each bristle 32a as shown in Figure 4, and each bristle 32a forms the looped pile shape on base cloth 32b.This looped pile brush 32 is during by scraping blade 33 clampings, as shown in Figure 6, be with base cloth 32b along will be arbitrarily the line that connects of the two ends of bristle 32a be bent into base cloth 32b gone up under the mutual opposed state in the inside with the stationary plane opposition side of each bristle 32a, with scraping blade 33 clampings.
In addition, in order to support looped pile brush 32 reliably with scraping blade 33, as shown in Figure 6, looped pile can be brushed 32 and be sewed together with scraping blade 33.
Under state like this, looped pile brush 32 is during by scraping blade 33 clampings, the line that the two ends of each bristle 32a of looped pile brush 32 are connected is along the above-mentioned direction of the 3rd support 33c of scraping blade 33, and this scraping blade has on a direction and the corresponding length in the whole zone of formation direction along the support 41b of revolving body 13 side faces.Therefore, under the state of clamping looped pile brush 32, when the 3rd support 33c of scraping blade 33 inserted support 41b, the line that the two ends of each bristle 32a of looped pile brush 32 are connected was along the formation direction of the support 41b of revolving body 13.Therefore, under this state, the line that looped pile brush 32 is connected for the two ends that make each bristle 32a is fixed on the base cloth 32b by the two ends with each bristle 32a, so that each bristle 32a is formed the looped pile shape along the formation direction of support 41b.
At this moment, at the side face of revolving body 13, no matter be that support 41b reverses formation mutually along rotating shaft formation or with gyratory directions, the looped pile part of each bristle 32a is provided with in the mode of the gyratory directions of crosscut revolving body 13.Thus, when under this state, making revolving body 13 revolutions, the face of the looped pile of each bristle 31a of formation looped pile brush 32 becomes state (the favouring gyratory directions) revolution of the gyratory directions of crosscut revolving body 13, as shown in Figure 7, even adhere to grease 14 on the floor, can brush 32 looped pile by looped pile and look like scraper and scrape like that and get this grease 14.Thus, according to the structure of the revolution of present embodiment brush 11, can brush 32 looped pile part with looped pile and effectively and reliably scrape and get grease 14.
At this, contact with floor in order to make looped pile brush 32, looped pile is brushed 32 maximum radius of gyration bottom line and is necessary for rotating shaft center from revolving body 13 to more than the distance of floor.In addition, the above-mentioned maximum radius of gyration is when the numerical value that adds 2mm than above-mentioned distance is also big, and abrasion, the damage of the looped pile brush 32 due to the friction of looped pile brush 32 and floor increase sharply, and can confirm that the durability of looped pile brush 32 becomes bad.
Therefore, the length of the radius of gyration direction of looped pile brush 32 wishes to set for, and to more than the distance of floor, and above-mentioned distance adds below the numerical value of 2mm the maximum radius of gyration of looped pile brush 32 from the rotating shaft center of revolving body 13.Thus, in the durability of keeping looped pile brush 32 to a certain degree, can obtain on 32 pairs of floor of looped pile brush scraping of grease 14 and get effect.
In addition, the length of the radius of gyration direction of looped pile brush 32 wishes to set for, the maximum radius of gyration of looped pile brush 32 less than from the rotating shaft center of revolving body 13 to the distance of antetheca 4a.Thus, can avoid the high-quality green tea of looped pile brush 32 to wear away, damage, looped pile can be brushed 32 as scraping the special-purpose brush of getting grease 14 on the floor because of contacting with antetheca 4a.At this moment, can make revolving body 13 revolutions contiguously, use thereby broad wool can be brushed 33 charged special-purpose brushes as antetheca 4a with high-quality green tea and the antetheca 4a that only makes broad wool brush 22.In addition, because the maximum radius of gyration of looped pile brush 32 less than the maximum radius of gyration of broad wool brush 22, when can protecting looped pile brush 32, can prevent that the end of a thread or the hair on the flannelette blanket is wrapped on the looped pile brush 32.
In addition, broad wool brush 22 is the scouring (the particularly xerotripsis on floor) that is used for floor as in the past, but in the present embodiment, because so the function of the scouring of floor is that looped pile brush 32 has, broad wool brush 22 can have and above-mentioned different in the past function, even antetheca 4a is charged, by antetheca 4a Electrostatic Absorption dust.In other words, the revolution of present embodiment brush 11 is owing to have the looped pile brush 32 of the scouring effect of farthest bringing into play floor, and the broad wool brush 22 that much less in the past was used for the floor scouring just can be used as the charged special-purpose brush of antetheca 4a.
So, the 1st feature of the present invention has been to use looped pile brush 32, but the 2nd be characterized as, and as the result who uses this looped pile brush 32, broad wool brush 22 has and different in the past functions.As a result, can be satisfied the scouring effect of floor and the revolution brush 11 and the suction inlet assembly 3 of removing effect of dust simultaneously.
Below, explain the length setting of the radius of gyration direction of broad wool brush 22.
In the present embodiment, carry out amount (broad wool brush 22 when each bristle 22a is assumed to straight line and the lap of the antetheca 4a) variation that (1) makes the high-quality green tea of broad wool brush 22 contact with antetheca 4a, the experiment that the static (kV) that produce this moment on antetheca 4a for which kind of degree changes, with carry out amount (the broad wool brush 22 when each bristle 22a is assumed to straight line and the lap of the floor) variation that (2) contacts the relative floor of high-quality green tea of broad wool brush 22, the experiment that the dust removal efficiency (%) of this moment for which kind of degree changes, according to its result, set the length of the radius of gyration direction of broad wool brush 22.
The experimental technique of above-mentioned (1) carries out as follows.That is, with after removing brush antetheca 4a and suction inlet 5 being removed electricity, the contact amount of broad wool brush 22 relative antetheca 4a has 3 kinds of variations, under each situation, revolution brush 11 is changeed 1 minute, at distance antetheca 4a5cm place, by static measuring device mensuration static.Fig. 8 illustrates the relation of the static value (kV) that produces at antetheca 4a the amount of contact (mm) of each bristle 22a and antetheca 4a and this moment, and Fig. 9 is for being the view that the basis makes above-mentioned both pictorializations with these measurement results.
For the experiment of above-mentioned (2), be method with " the performance measurement method of home-use electronic dust catcher " regulation of JIS (JIS) C9802, carry out the mensuration of dust removal efficiency.Dust removal efficiency is the ratio that follows the amount of dust that the amount of dust of removing in the looped pile and trial stretch scatter with the fixed removing of percentage table first finger, that is, and and (amount of dust of amount of dust/distributions of removing with stipulated number) * 100 numerical value of representing.Figure 10 is with each bristle 22a and the amount of contact (mm) of floor and the view that concerns pictorialization of the dust removal efficiency of this moment.
According to the result of Fig. 9, broad wool brush 22 and the amount of contact of antetheca 4a be 1mm above, below the 2mm, also can produce the static of absorption dust of the minimum 0.4kV of being of sufficient quantity.Thus, the length of the radius of gyration direction of broad wool brush 22 wishes to set for, and above-mentioned contact amount is more than the 1mm, below the 2mm, promptly, the maximum radius of gyration of broad wool brush 22 adds more than the numerical value of 1mm for the distance from the rotating shaft center of revolving body 13 to antetheca 4a, and above-mentioned distance adds below the numerical value of 2mm.Thus, antetheca 4a is gone up produce sufficient static, can improve the efficient of removing of dust reliably.Particularly, when above-mentioned contact amount is 1.5mm,, can obtain optimum efficiency according to the result of Fig. 9.
At this moment, looped pile brush 32 does not contact with antetheca 4a, consider when broad wool brush 22 is 2mm to the maximum with the amount of contact of antetheca 4a, the length difference of the radius of gyration direction of the length of the radius of gyration direction of broad wool brush 22 and looped pile brush 32 is at (still, the maximum radius of gyration of broad wool brush 22 is greater than the maximum radius of gyration of looped pile brush 32) more than the 1mm, below the 2mm.
According to the result of Figure 10, the amount of contact of broad wool brush 22 and floor is more than 1mm, when 2mm is following, and dust removal efficiency can obtain the numerical value near peak value (73.5%), can improve the effect of removing of dust obviously.Thus, the length of the radius of gyration direction of broad wool brush 22 wishes to set for, above-mentioned contact amount be 1mm above, below the 2mm, that is, the maximum radius of gyration of broad wool brush 22 adds more than the numerical value of 1mm, adds below the numerical value of 2mm in above-mentioned distance for the distance from the rotating shaft center of revolving body 13 to floor.Thus, can obtain to remove effect by revolution brush 11 all higher dusts of realizing.Particularly, when above-mentioned contact amount is the corresponding 1.4mm of peak value (73.5%) with dust removal efficiency,, can obtain optimum efficiency according to the result of Figure 10.
According to above-mentioned, in order to make antetheca 4a (be preferably 1.5mm) more than the 1mm, below the 2mm with the amount of contact of broad wool brush 22, and floor (is being preferably 1.4mm) with the amount of contact of broad wool brush 22 more than the 1mm, below the 2mm, supporting by 4 of baskets as revolving body 13 (or revolution brush 11), can produce the static of sufficient Chued dust, much less, can remove dust on the floor reliably.
In addition, according to the use of broad wool brush 22, can be adjustable straightening hairbrush 22 and the structure of the amount of contact of floor.For example, (1) can during 22 wearing and tearing of broad wool brush, move above-mentioned rotating shaft with the rotating shaft of revolving body 13 (or revolution brush 11) in the above-below direction adjustment towards the direction near floor, above-mentioned contact amount can be dropped in the above-mentioned applicable scope.In addition, (2) height and position of the wheel that suction inlet assembly 3 can be moved along floor is in the above-below direction adjustment, during 22 wearing and tearing of broad wool brush, because the position of above-mentioned wheel promotes from floor, broad wool brush 22 shorten relative with the distance of floor, thus, above-mentioned contact amount can be dropped in the above-mentioned applicable scope.
; when the looped pile brush 32 of present embodiment inserts the support 41b of revolving body 13 at the scraping blade 33 with clamping looped pile brush 32; the line that connects each bristle 32a two ends is along the formation direction of support 41b; but when scraping blade 33 was inserted support 41b, the line that connects each bristle 32a two ends can be along the gyroaxis direction of revolving body 13.That is, looped pile brush 32 can be by the line that connects each bristle 32a two ends is fixed to the two ends of each bristle 32a on the base cloth 32b along the gyroaxis direction ground of revolving body 13, and each bristle 32a is formed the looped pile shape.
So looped pile brush 32 can by the folding line of for example base cloth 32b only consider support 41b gyratory directions the degree of reversing and bend base cloth 32b with mode that the folding line of Fig. 1 and Fig. 6 tilts, come to realize with scraping blade 33 clampings.At this moment, when bending base cloth 32b also uses scraping blade 33 clampings, the line that the two ends of each bristle 32a among the base cloth 32b are connected not with the length direction of the corresponding scraping blade 33 of formation direction of support 41b, but when being inserted in scraping blade 33 among the support 41b that the gyratory directions of revolving body 13 reverses, the line that base cloth 32b goes up the two ends that connect each bristle 32a is just along the gyroaxis direction of revolving body 13.Brushed 32 o'clock at the looped pile that so constitutes, form the face of looped pile among each bristle 32a of looped pile brush 32 since be fully perpendicular to the state turning down of the gyratory directions of revolving body 13, can obtain on the floor scraping of grease 14 to greatest extent and get effect.
In the present embodiment, the 1st brush portion 21 is made of broad wool brush 22, but the available scraping blade that taps the dust on the flannelette blanket replaces broad wool brush 22 to form.So long as the dust on the flannelette blanket is scraped and is got effect and all can than the strong structure of above-mentioned charged effect due to the broad wool brush 22.
In addition, the diameter of each bristle 32a of looped pile brush 32 is thin more, scraping of the grease 14 on the floor got performance and just improved more, but its durability can descend (sharply increasing with the damage due to the friction of floor).Therefore, the diameter of each bristle 32a can consider to scrape setting aspect the balance of getting performance and durability.In addition, even, also can take into account the durability of each bristle 32a and set for the density of each bristle 32a.
In addition, the bristle that is provided with on the bottom surface of suction inlet assembly 3 body 6 in upright arrangement (with reference to Fig. 3) can be made of above-mentioned looped pile brush 32.At this moment, the line that with the moving direction of the looped pile face crosscut suction inlet assembly 3 of looped pile brush 32, promptly connects each bristle 32a two ends gets final product looped pile brush 32 bottom surfaces that are installed on suction inlet assembly 3 that the two ends of each bristle 32a are fixed on the base cloth 32b along the axial mode of the revolution of revolving body 13.
Embodiment 2
Below, according to Figure 11～Figure 15 (a) and (b) explanation other embodiment of the present invention.The structure identical with embodiment 1 is marked by identical symbol, omits its explanation at this.
In the present embodiment, (with reference to Fig. 1, Fig. 6) by outside the 2nd brush portion 51 replacements shown in Figure 11, other are identical with embodiment 1 except the 2nd brush portion 31 with embodiment 1.The 2nd brush portion 51 is made of the looped pile brush 32 and the scraping blade 52 (elastomer) that use among the embodiment 1 as shown in figure 11.
Scraping blade 52 is for the member of supporting looped pile brush 32, by the 1st support 52a that pastes this looped pile brush 32, and the 2nd support 52b formation that when being connected, with the section configuration of the support 41b that can insert revolving body 13, forms with the 1st support 52a.By the 2nd support 52b of scraping blade 52 being inserted the support 41b of revolving body 13, scraping blade 52 integral body are bearing on the revolving body 13 by support 41.
The 1st support 52a and the 2nd support 52b have and the corresponding length of formation direction universe along the support 41b of the side face of revolving body 13.Thus, when the 2nd support 52b of scraping blade 52 inserted the support 41b of revolving body 13, the 1st support 52a of scraping blade 52 spreads all over the whole of formation direction of the support 41b of revolving body 13 regionally to be given prominence to from the side face of revolving body 13.Therefore, it is outstanding from the side face of revolving body 13 that scraping blade 52 is arranged to spread all over the ground, whole zone of formation direction of support 41b.
In the present embodiment, looped pile brush 32 as shown in figure 12, the mode that covers by the leading section 53 as the outstanding front end of scraping blade 52 with each face in the gyratory directions upstream side of the revolving body in the scraping blade 52 13 and downstream goes up the base cloth 32b of looped pile brush 32 and the inside of the stationary plane opposition side of each bristle 32a pastes on the scraping blade 52.At this moment, looped pile brush 32 pastes on the scraping blade 52 under the state that connects the line bending at bristle 32a two ends arbitrarily at base cloth 32b.In addition, above-mentioned stickup can be that the formula of making is pasted, and also can be to use the stickup of bonding agent.
Constitute so the 2nd brush portion 51, under looped pile brush 32 situations about pasting on the scraping blade 52, the line that each bristle 32a two ends of looped pile brush 32 are connected is along the direction of the 2nd support 52b of scraping blade 52, and this direction has and the corresponding length in the whole zone of formation direction along the support 41b of the side face of revolving body 13.Therefore, when the 2nd support 52b that looped pile brush 32 is pasted the scraping blade 33 on the 1st support 52a inserted support 41b, the line that the two ends of each bristle 32a of looped pile brush 32 are connected was along the formation direction of the support 41b of revolving body 13.
Thus, when under this state, making revolving body 13 revolutions, the face of the looped pile of each bristle 31a of formation of looped pile brush 32 is the state turning down with the gyratory directions of crosscut revolving body 13, therefore, similarly to Example 1, can brush 32 looped pile part by looped pile and scrape off grease on the floor effectively, and can scrape reliably and get.
Next, in the present embodiment, the structure of revolution brush 11 is carried out various variations, with the experiment of the cleaning effect of testing floor.Figure 13 illustrates the experimental result of each specification of revolution brush 11.
Batch No.1 is and is brushed and 2 identical members of revolution brush in the past that scraping blade constitutes by 2 broad wool that No.2 and batch No.3 are the revolution brush 11 with present embodiment of 2 the 1st brush portions 21 (broad wool brush 22) and 2 the 2nd brush portions 51 (looped pile brush 32+ scraping blade 52) in batches.But in batch No.2 and batch No.3, the maximum radius of gyration of looped pile brush 32 and scraping blade 52 is different.In addition, No.4 brushes for the revolution with 2 scraping blades and 2 the 2nd brush portions 51 (looped pile brush 32+ scraping blade 52) in batches.In addition, the looped pile of No.2～batch No.4 brush 32 uses the looped pile brush of hair high (each bristle 32a is apart from the height of base cloth 32b) as 4mm in batches." φ " among the figure represents tactical diameter (mm), is the maximum radius of gyration (mm) * 2.
The object of removing is to add impression of the hand (oil content) on the blackboard and the dust on the flannelette blanket (Mao Gaowei 7mm) to.Experimental technique is to make that revolution brush is rotating to move back and forth suction inlet assembly 3 simultaneously on the blackboard He on the flannelette blanket.In addition, the current value among the figure is for making the rotating driving current value of revolution brush.For dust removal efficiency as described in the embodiment 1.In addition, show as operating physical force and suction inlet assembly 3 is advanced on flannelette blanket or retreat necessary power.
According to the result of Figure 13, in batch No.1, dust on the flannelette blanket is shown, and to remove effect (dust removal efficiency) higher, but the impression of the hand on the blackboard is removed effect and almost do not had.In addition, in batches the revolution of No.1 brush is after on the blackboard reciprocal 2 times, 2 broad wool brushes is replaced by the have 2 looped piles brushes revolution brush of (Mao Gaowei 6mm, the density of bristle 32a is bigger than the looped pile brush of No.2～No.4), it reciprocal 1 time the time, just can be wiped the impression of the hand of getting on the blackboard fully on blackboard.
In addition, among No.2 and the batch No.3, for the effect of removing of the dust on the flannelette blanket, No.1 compares with batch in batches, and numerical value is lower, but changes hardly., for the effect of removing of the impression of the hand on the blackboard, though wiping number of times error more or less, No.1 compares with batch, and it is remarkable to confirm to remove effect.In addition, in batches among the No.4, the impression of the hand on the blackboard is removed effect with batch No.2 with No.3 is identical in batches, and for the dust on the flannelette blanket to remove effect identical with batch No.1.
According to above result, can think that at least the batch No.2～batch No.4 that uses looped pile brush 32 compares with the batch No.1 that brushes 32 without looped pile, oil content to remove effect higher.Particularly, in batch No.4, that the drive current of revolution brush 11 can be suppressed must remove oil content than the lowland.
As present embodiment, looped pile brush 32 is being wound on the scraping blade 52 when forming the 2nd brush portion 51, as shown in figure 14, can looped pile be brushed 32 in the mode that forms the space of regulation between the leading section 53 of the inside of the base cloth 32b of looped pile brush 32 and scraping blade 52 pastes on the scraping blade 52.At this moment, the impact when looped pile brush 32 contact with floor can be by the space absorption of afore mentioned rules, can alleviate looped pile and brush 32 damage.
In addition, by being provided with the space of afore mentioned rules, during 32 revolutions of looped pile brush, can make looped pile brush 32 be deformed into the gyratory directions upstream side of keeping out of the way revolving body 13 in the looped pile brush 32 with the contact site of floor.Thus, when looped pile brush 32 so was out of shape, looped pile brush 32 carried out face with floor and contacts, and can further improve the scouring effect of 32 pairs of floor of looped pile brush.
Below, in the present embodiment,, the durability of looped pile brush 32 is experimentized with the 2nd brush portion 51 shown in Figure 11 and the 2nd brush portion 51 shown in Figure 14.Figure 15 (a) and (b) illustrate the cleaning object carries out durability when being floor and flannelette blanket to looped pile brush 32 experimental result respectively.
In addition, in batches No.5 is revolution brush 11, and this revolution brush 11 has in the mode that does not form the space between the leading section 53 of the inside of base cloth 32b and scraping blade 52 brushes 32 the 2nd brush portions 51 (with reference to Figure 11) that paste on the scraping blade 52 with looped pile.In addition, in batches No.6 and in batches No.7 be revolution brush 11, this revolution brush 11 has in the mode in formation space between the leading section 53 of the inside of base cloth 32b and scraping blade 52 brushes 32 the 2nd brush portions 51 (with reference to Figure 14) that paste on the scraping blade 52 with looped pile.But, in batch No.6 and batch No.7, although some difference of the rotating speed of the 2nd brush portion 51 can be thought in error range.
In addition, in batch No.5 and batch No.6, each 31a of brush portion of looped pile brush 32 is made of identical fibre (for example nylon), and base cloth 32b is made of the fiber (for example nylon+polyurethane) of easy stretching.Among the No.7, each 31a of brush portion and the base cloth 32b of looped pile brush 32 constitute by nylon in batches.Scraping blade 52 each thickness of No.5～batch No.7 are 0.6mm in batches.
Be known as below the result according to above experiment:
When (1) the space not being set between looped pile brush 32 and scraping blade 52, the resistance of looped pile brush 32 relative floor becomes big, and the durability of each bristle 32a of looped pile brush 32 becomes bad.In addition, when being provided with above-mentioned space,, can improve the durability of each bristle 32a because of having reduced above-mentioned resistance.
(2) in batches No.5 can think by revolution tensile fiber, and with the grow that contacts of floor, the abrasion of each bristle 32a increase.
(3) No.5 compares with batch No.7 with batch No.6 in batches, because looped pile partly becomes loose slightly shape, so even have abrasion also to be difficult for finding slightly.
