Particularly, connect mechanism 216 keeps the front end 213 of connecting cylinder 215 to make it to swing freely on the thickness direction of shell 214.Again, connect mechanism 216 self rotates freely and installs with respect to shell 214.Rotation direction is the direction around the axle that links tube 215.
Thereby, by with respect to shell 214 and 90 ° rotate connect mechanisms 216, the front subtend that makes shell 214 under this state is in swept surface 400, suction unit 205 just can make the length direction of shell 214 become the vertical-position of holding up towards upper and lower with respect to swept surface 400 shown in Fig. 8～10.
At this, Fig. 8 is the rearview when making suction unit 205 for vertical-position, and Fig. 9 is the part sectioned view of Fig. 8, and Figure 10 is the right side view when making suction unit 205 for vertical-position.
And then Figure 11 is the upward view of the suction unit 205 of vertical-position.
In the part sectioned view of Fig. 9, the state of the rotating brush 232 in the expression vertical-position shell 214 down, the state of air register 225 and being used to makes the existence of the motor 237 that rotating brush 232 rotates.This part section is not the central section of the width of shell 214, but the section of the part that width is kept right.
Illustrate that with reference to Fig. 8～Figure 11 if make suction unit 205 be vertical-position, thereby then air register 225 is open by pressing on the swept surface 400.Air register 225 is under the situation of basic form at suction unit 205, utilizes the ejection force of not shown spring and drops to the below, becomes the closed condition of the front of closing shell 214.But, when suction unit 205 switched to vertical-position, air register 225 became the open mode of the front of open shell 214 by pressing on the swept surface 400.With this, the secondary suction inlet 238 that is formed on the front of shell 214 is open, secondary suction inlet 238 and swept surface 400 subtends.Thereby suction unit 205 can suck dust from the secondary suction inlet 238 with swept surface 400 subtends under vertical-position.
And then, with reference to Fig. 8, if air register 225 becomes open vertical-position, then at the width two ends of shell 214, that is, in the front face side (under the vertical-position at Fig. 8, with a side of swept surface 400 subtends) of shell 214 auxiliary suction inlet 239 appears.Auxiliary suction inlet 239 be at suction unit 205 when moving on the width of shell 214, promptly at suction unit 205 when moving forward and backward under the vertical-position, at the open suction inlet of this moving direction side.Thereby, when suction unit 205 moves, because auxiliary suction inlet 239 is arranged, so even bigger dust is arranged on swept surface 400, this dust also is inhaled in the shell 214 well from this auxiliary suction inlet 239 in this moving direction side.
At suction unit 205 is under the vertical-position, butt roller 226 and fleece 240 on swept surface 400.As mentioned above, roller 226 is installed on the two ends (two ends when observing) of air register 225 on the width of shell 214.On the other hand, as shown in figure 11, fleece 240 is arranged at two jiaos of the bottom surfaces of a side that does not dispose roller 226.Thereby, looking up when observing, the suction unit 205 of vertical-position, its subtend utilizes 2 rollers 226 and 2 fleeces 240 to be stabilized supporting in four jiaos of swept surface 400.
In other words, with reference to Fig. 8 and Figure 11, the suction unit 205 of vertical-position respectively disposes roller 226 and fleece 240 in the front of the shell 214 of swept surface 400 on four jiaos in subtend, thereby shell 214 is supported by these 4 and becomes stable vertical-position.And, and the contact 241 of swept surface 400 between, secondary suction inlet 238 becomes the state of opening.
In addition, roller 226 and fleece 240 at the suction unit 205 of vertical-position when moving on the swept surface 400, promptly suction unit 205 is brought into play function as being used for carrying out this mobile accessory that moves smoothly when right and left moves up in Figure 10.Thereby, under state as shown in Figure 3, holding secondary handle 208, and utilizing when the mobile suction unit 205 in suction line ground, 204 front and back, on one side suction unit 205 can keep stable vertical-position, Yi Bian on swept surface 400, move smoothly.
Again, in Figure 10, the front end 231 of connecting cylinder 215 has been rotated 90 ° connect mechanism 216 swings maintenance freely with respect to shell 214, and this swaying direction is the oblique left and right directions upwards of taking back with arrow 242 expressions in Figure 10.Thereby, can will be connected in suction line 204 (with reference to Fig. 3) and the angle of secondary handle 208 and the angle and the position that the position is made as processing ease of connecting cylinder 215, thus the suction unit 205 of operation vertical-position.
Again under this situation, as shown in Figure 8, the axle core of connecting cylinder 215 is positioned on the thickness direction center line of shell 214 with respect to the shell 214 of vertical-position.Thereby the shell 214 of vertical-position utilizes connecting cylinder 215 and remains poised state stable, processing ease.
Figure 12 and Figure 13 are used to illustrate the rotary figure that is connected structure suction unit 205, shell 214 and connect mechanism 216, are vertically to block the state of shell 214 from the observed orthogonal view of face side on width.
Figure 12 is the profile that shell 214 and connect mechanism 216 are in the position relation shown in Fig. 5,7, and Figure 13 is the profile that shell 214 and connect mechanism 216 are in the position relation shown in Fig. 8,10.
With reference to Figure 12,13, on connect mechanism 216, has the flange 243 that is disposed in the shell 214 in its front.Flange 243, its inner peripheral 244 forms suction inlets, and its periphery comprises circular-arc periphery 245, separating 2 lockings of position upper cut of 180 ° with respect to the center with concave face 246 and be formed at relative center and separate 90 ° usefulness plane 247, locational 2 location with lock recess face 246.
On the other hand, in shell 214, dispose locking plate 248 with flange 243 adjacency.Locking plate 248 utilizes helical spring 249 often towards the periphery elastic force ejection of flange 243.
As shown in figure 12, under the situation of location with side's butt on plane 247 of locking plate 248 and flange 243, connect mechanism 216 cards only make and stop on its turned position when being fit to shell 214 for basic form.Connect mechanism 216 rotational angle under locating with the state of plane 247 and locking plate 248 butts is positioned, but can easily carry out rotating connect mechanism 216 these operations with respect to shell 214 from this state.
On the other hand, as shown in figure 13, connect mechanism 216 is being turned to when being suitable for shell 214 for the angle of vertical-position, in locking with embedding locking plate 248 on the concave face 246.And, under this state,, then can not change both angle positions if do not reverse shell 214 and connect mechanism 216 with great power.Promptly, when making suction unit 205 for vertical-position, connect mechanism 216 becomes turned position as shown in figure 10 with respect to shell 214, but when this state, turned position with respect to the connect mechanism 216 of shell 214, as shown in figure 13, utilize locking to engage with locking plate 248 and be locked in this angle position with concave face 246.Thereby under vertical-position as shown in figure 10, connect mechanism 216 is not easy to rotate with respect to shell 214, can be under the fixing state in the shell 214 and the angle position of connect mechanism 216, and tube 215 only is rotationally connected on arrow 242 directions.Thereby, at connecting cylinder 215, in other words be linked on the length direction of the suction line 204 on the connecting cylinder 215, shell 214 extends under upright state, shell 214 does not rotate, so following advantage is arranged: can successfully be used in gap cleaning under the state of vertical-position at shell 214.
Figure 14 is the figure that is used to illustrate the variation that is provided to the mobile accessory on the suction unit 205, and expression suction unit 205 is the rearview of vertical-position.Again, Figure 15 is the upward view of suction unit 205 as shown in figure 14.
With reference to Figure 14 and Figure 15, paired roller (two roller) 250 on suction unit 205, is equipped with, it is under the vertical-position that described roller 250 is used at shell 214, auxiliaring shell 214 moves on width.In the front face side of shell 214, two rollers 250 are disposed at the width both sides of shell 214.Thereby when shell 214 became vertical-position, Qi Sijiao became the state that is stably supported by two rollers 250.Again, two rollers 250 are installed to be rotation freely.Thereby shell can successfully move forward and backward at width.
More specifically, two rollers 250 are following structures: have support unit 251 on the width both sides of the front face side that is disposed at shell 214, remain on the support unit 251 and the fulcrum 252 that extends on the thickness direction of shell 214 and 2 rollers 253 that rotate the two ends that remain in fulcrum 252 freely.
In addition, in this structure, two rollers 250 are not installed on the air register, thereby the on-off action of air register is irrelevant with the state of two rollers 250.
Figure 16 is used for explanation when suction unit 205 is vertical-position, the figure of another structure example that is used for the mobile accessory that moves of auxiliaring shell 214, be the rearview of the suction unit 205 of vertical-position, Figure 17 is the upward view of suction unit 205 as shown in figure 16.
With reference to Figure 16 and Figure 17, on the suction unit 205 of present embodiment, be not provided as the roller of mobile accessory, bring into play function as mobile accessory but be pasted on when air register 225 is open the fleece 254 of subtend on the face of the air register of swept surface 400.
That is, be under the vertical-position at suction unit 205, suction unit 205 utilizes fleece 254 and fleece 240 to be contacted with on the swept surface 400.Therefore, these fleece 254,240 auxiliary suction units 205 are being displaced on the swept surface 400 on the width of shell 214.
Such structure is compared with the structure that is provided with roller 226 or two roller 250, have can implementation structure this advantage of simplicity.
Figure 18 A and Figure 18 B are respectively the upward views of the suction unit 205 of vertical-position, be illustrated in subtend and be pasted with lead fleece 255,256 these structures of secondary suction inlet of the dust that is used for swept surface on the air register face of swept surface.In Figure 18 A, suction unit 205 is directed into secondary suction inlet 238, the particularly shape among the hole 215a of the connecting cylinder of opening above secondary suction inlet 238 because move up at upper and lower so preferably do to become dust this moment.
That is, on the width of shell 214,, be provided with the spigot surface 257 that dust is directed at the thickness direction center side of shell 214 in width central authorities.Spigot surface 257 can be shown in Figure 18 A, is the chevron of linearity of the width central uplift of shell 214, can be the spigot surface 258 that is depicted as crooked mountain shown in Figure 18 B also.
And then these guides can be the guides that forms step in the subtend of for example air register 225 on the face of swept surface 400 under the prerequisite that does not constitute with fleece 255,256, and described step forms spigot surface 257 or 258.
Figure 19 is the figure of the variation of expression air register 225, is the front view of suction unit 205.As shown in figure 19, under air register 225 closing state, can constitute air register 225 in the mode that between the bottom 259 of air register 225 and swept surface 400, forms gap 260.Under this situation, when suction unit 205 is basic form, exist not by the gap 260 of air register 225 obturations in the front face side of suction unit 205.Also there is the secondary suction inlet 238 that links with main suction inlet 224 in shell 214 except being formed with in its bottom surface the main suction inlet 224 in its front.And since gapped 260 between air register 225 and swept surface 400, so dust utilizes this gap 260 to be inhaled into from secondary suction inlet 238.
Particularly, when suction unit 205 advances with basic form, can suck the dust on the swept surface 400 that is positioned at its place ahead well from above-mentioned gap 260.
Figure 20 is the figure of the another variation of expression air register 225, is that suction unit 205 is the front view of basic form.
In the structure of Figure 20, air register 225 its bottoms 259 become have concavo-convex limit on the widths of shell 214.Therefore, less clearance 260 and bigger gap 261 on the width alternately landform be formed between the bottom 259 of swept surface 400 and air register 225.Utilize these gaps, suction unit 205 just can when move in the place ahead, attract to be positioned at the dust in its place ahead well under basic form.
Figure 21～Figure 23 is right side view, the front view of basic form and the front view of vertical-position of basic form of the suction unit 265 of other embodiment of the present invention.
With reference to Figure 21～Figure 23, suction unit 265 is characterised in that the front of shell 214 is formed with a plurality of louver(-vre)s 267 by header board 266 obturations on header board 266.For example 5 of a plurality of louver(-vre) 267 concrete arrangements, these louver(-vre)s 267 are arranged on the width of suction unit 265.Thereby suction unit 265 can utilize these a plurality of louver(-vre)s 267 to suck the dust that is positioned at its place ahead.
Again, header board 266 does to become its bottom 268 to be become have concavo-convex limit on the width of shell 214, make and swept surface 400 between generate gap 269.Therefore, also can utilize this gap 269 to suck the dust in shell 214 the place aheads.
If make to become such structure, then make suction unit 265 under the state of vertical-position, louver(-vre) 267 and swept surface 400 subtends, thus can attract dust on the swept surface 400 via louver(-vre) 267.Thereby, according to this structure, can make suction unit 265 air register, simpler structure is not set.
In addition, in Figure 21～Figure 23, the 270th, roller, the 271st, fleece, they are as the mobile accessory of the shell under the upright state 214 and bring into play function.
Remaining structure is identical with the suction unit 205 of the embodiment that illustrates before, so the part of correspondence is marked corresponding symbol, the repetitive description thereof will be omitted.
Figure 24 is the figure of other structure of expression suction unit, is the vertical view of suction unit when being basic form.Suction unit 275 is as shown in figure 24 compared with suction unit 205 as shown in Figure 7, is used for connecting cylinder 215 is connected in the structure difference of the connect mechanism 276 of shell 214.
Figure 25 observes from the right side at fore-and-aft direction to have blocked the vertical section of central authorities of suction unit 275 as shown in figure 24 and the right side profilograph that obtains.
With reference to Figure 24 and Figure 25, connect mechanism 276 is center and rotate on left and right directions and keep connecting cylinder 215 freely with its front end, and connect mechanism 276 self rotates freely on thickness direction with respect to shell 214 and links.Therefore, shell 214 is under basic form, connect mechanism 276 rotates on above-below direction with respect to shell 214, rises so the suction line that front end remains in the connecting cylinder 215 on the connect mechanism 276 and is linked to the rear end side of connecting cylinder can extend to oblique rear with the angle of hope with respect to shell 214.Again, because this angle is because of the rotation displacement of connect mechanism 276, so can not diminish operability.
And then connecting cylinder 215 can utilize connect mechanism 276 to rotate on the width of shell 214.Thereby, because shell 214 promptly extends to the suction line 204 direction swing to the left and right at the rear of connecting cylinder 215 with respect to connecting cylinder 215, so can not diminish operability.
On the other hand, as shown in figure 25, have be used for connecting cylinder 215 to the rear of shell 214 approximate horizontal under the state given prominence to, the banking pin 277 that restriction connect mechanism 276 rotates with respect to shell 214.Banking pin 277 often by helical spring 278 elastic force ejections to the top.And, have on the connect mechanism 276 when the rotational angle of connect mechanism 276 becomes level with respect to shell 214, accept the recess 279 of the front end of banking pin 277.
Therefore, in suction unit 275, by connecting cylinder 215 is the state that flatly is projected into the rear of shell 214, and under this state, make shell 214 be vertical-position, connect mechanism 276 is not gone up at left and right directions (thickness direction of shell) with respect to the shell 214 of vertical-position and is rotated, and is fixed on from the shell 214 of vertical-position to be projected on the position of top.And because connecting cylinder 215 can rotate on the width of shell 214 with respect to this fixing connect mechanism 276, the connecting cylinder 215 so can tilt at the width of shell 214, thus easily operate the shell 214 of vertical-position before and after the width.
Promptly, suction unit of the present invention possesses shell, connect mechanism and connecting cylinder, but the structure of connect mechanism, connecting cylinder is not limited to connect mechanism, the connecting cylinder of explanation such as Fig. 7, also can use Figure 24, the connect mechanisms of 25 explanations, the structure of connecting cylinder.
Figure 26 is the schematic diagram that expression is inserted into suction unit 205 as shown in Figure 8 for gap cleaning this state in the gap.As shown in figure 26, if make suction unit 205 be upright state, then suction unit 205 can be inserted and compare the wide slightly gap of thickness of shell 214, thereby can easily carry out the cleaning in such gap.And, be used for atraumatic fleece 228, flexure strip 229, fleece 230 etc. because have on the shell 214 of the suction unit in being inserted in the gap 205 or the connect mechanism 216, so even suction unit 205 collides furniture or wall, also can prevent furniture or wall equivalent damage.
In addition, in so far embodiment of explanation, shell 214 illustrations of vertical-position under air register 225 opened state, the thickness of its upper end and the thickness of bottom shell about equally.But, as shown in figure 27, also can make to become following structure: open by air register 225 when suction unit 205 is vertical-position, make that in the bottom and upper end of shell 214 thickness of bottom is wide.With this, the stability of the shell 214 of vertical-position increases.
In addition, be under the vertical-position situation of cleaning making suction unit, preferably in the rotation of rotating brush 232, work hard.
When making suction unit 205 for vertical-position, as shown in Figure 9, main suction inlet 224 is at the lateral opening of the shell 214 of vertical-position.Therefore, when being basic form with shell 214 similarly, under the situation of rotation rotating brush 232, rotating brush 232 left-handed rotation in Fig. 9, so sometimes the dust on the swept surface of kicking up by rotating brush 232 400 from main suction inlet 224 side that flies out.
Therefore, making shell 214, preferably make the rotation of rotating brush 232 and the situation of basic form be in a ratio of low speed under the situation of vertical-position.
Make shell 214 under the situation of vertical-position, the rotation of the brush 232 that also can stop the rotation again.
Perhaps, when making shell 214 for vertical-position, the direction of rotation in the time of also can making the direction of rotation of rotating brush 232 be basic form with shell 214 is opposite.That is, in Fig. 9, dextrad rotation rotating brush 232.Like this, by flowing of the dust of rotating brush 232 elevators not towards main suction inlet 224 1 sides, but in shell the side, so, do not have dust from the fly out anxiety of side of main suction inlet 224 even shell 214 is a vertical-position yet.
Rotating under the situation of rotating brush 232 to contrary direction as mentioned above, also the rotary speed of rotating brush 232 can suppressed for lower.
In addition, under the situation of contrary rotation rotating brush 232 as mentioned above, following advantage is also arranged: near the stage portion the ground of wall is kicked up by rotating brush 232 caused wind, thereby can stir the dust near the rib wood that falls to being stranded in step surface or the floor well.
And then, be schematically shown as Figure 28, make suction unit 205 be vertical-position, and under the state of the electric blower of inoperation electric dust collector main body 201, only forward under the situation of (the identical direction of direction when be basic form with suction unit 205) rotation rotating brush 232, rotating brush 232 performance functions are feasible has swept dust on the swept surface 400 with broom.That is, make suction unit 205 be vertical-position, and under the situation of the electric blower of inoperation electric dust collector main body 201,, then having and as broom, to use this purposes of electric dust collector if only rotate rotating brush 232.
The present invention is not limited to the content of above embodiment, can carry out various changes in the scope of claim record.
