Fig. 2 and Fig. 3 are respectively the top and bottom perspective views behind the upper member that takes off inhalator, and Fig. 4 is the cutaway view of the A-A line of Fig. 3.Illustrated inhalator 8 by front and back length less than the inhalator body 9 of left and right sides length be located at these inhalator body 9 rears and the other end and prolong pipe 7 connecting portions that are connected 10 and constitute, substantial middle below inhalator body 9 is provided with suction inlet 11, and this suction inlet 11 is communicated with the dust suction path 12 that extends along its length direction below inhalator body 9.Again, in dust suction path 12, be provided with and draw the revolution brush 13 that dust is used in, transmit turning power by belt 14A by the drive motors 14 that is provided in rear in the inhalator body 9.The suction path that is provided with aftermentioned central authorities in the reverse side of drive motors 14 is sandwiched in therebetween, is used to make drive motors 14 and the loop substrate 16 that is electrically connected usefulness from the lead 15 of connecting portion 10.
Again, flannelette 17 is posted in the both sides in the place ahead below inhalator body 9, and the rear is equipped with the rear roller 18 that can swing freely below.
As shown in Figure 4, inhalator body 9 constitutes shell by upper member 19 and lower member 20, be located at the suction path 21 that lower member 20 following suction inlets 11 are communicated with the connecting portion 10 at inhalator body 9 rears in order to form to make, between lower member 20 and upper member 19, set intermediate member 22, will surround the space of intermediate member 22 and lower member 20 as sucking path 21.
Again, intermediate member 22 is made of dome part 22A that forms suction path 21 and circular-arc bridge shape part 22B, and this bridge shape part 22B forwards stretches out from middle member 22, and the top of turning round brush 13 is covered, and its front portion is by upper member 19 and lower member 20 clampings.Shown in Fig. 7 (partial perspective view of intermediate member), on this bridge shape part 22B, be formed with and handle path 23, be used to keep the lead 15 of drive motors 14, carry out distribution via the top of revolution brush 13 to loop substrate 16 and handle.
Under common user mode, inhalator body 9 is leaned against on the wall in room or after tramping with one's feet, can be made its anterior and top deflection easily.This is to cause the gas leakage that sucks in the path 21 and change with the gap of swept surface and reduce the main cause of dust collecting performance.Therefore, as previously mentioned, constitute intermediate member 22, guarantee stable suction path 21 with this by central portion at inhalator body 9.
Again, the part of upper member 19 is that intermediate member 22 is formed a big dome shape around top one circle that the dome shape sucks path 21, and forms the space in the middle of intermediate member 22.This space becomes the space that can pass from the lead 15 and the removable lead 15 of connecting portion 10 described later.Promptly, this space is in order to ensure the space of allowing that deflections take place lead 15 when connecting portion 10 is swung, has the good function of province's volume and assembleability, owing to form and to swing the space of distribution freely from the lead 15 of connecting portion 10 at the upside that sucks path 21, therefore, also can obtain the cooling effect of lead 15.
Again, be provided with the outlet 9A that sucks path 21 at the rear portion of the inhalator body 9 that connects connecting portion 10, the 9B of swinging mounting portion that is formed by upper member 19 and lower member 20 is positioned at this outlet 9A place.The 9B of this swinging mounting portion is formed by the ring-type slot part of diameter greater than the outlet 9A that sucks path 21.
Fig. 5 is the partial top view of taking off behind the upper member of connecting portion.As Fig. 1 and shown in Figure 5, connecting portion 10 can be swung first connector 24 of installation freely by the joint face at relative inhalator body 9 rear portions and constitute along swinging second connector of installing freely 25 with first connector, 24 swaying direction vertical direction, and the bellows 26 that has the pliability tube connector by formation connects first connector 24 and second connectors 25.
Again, shown in first connector as shown in Figure 6 and the exploded perspective view of second connector, on first connector 24, be provided with the swing part 27 of ring-type, around this swing part 27, have the chimeric endless groove of ring-type slot part with the 9B of swinging mounting portion (Fig. 4) of inhalator body 9.And the slot part by the 9B of swinging mounting portion and the groove of swing part 27 are chimeric, form maze-type structure, connect on the air-tightness basis of swing part 27 guaranteeing.
One end of bellows 26 is connected with the peristome of swing part 27, and the outlet 9A that will suck path 21 is communicated with an end of bellows 26, the other end of bellows 26 is connected with connecting portion 28 on being fixed on second connector 25.
As shown in Figure 5 and Figure 6, on the swing part 27 that constitutes first connector, 24 parts, roughly the L font arm 29 extend along two side directions, this arm 29 constitutes the swing axial region 30 of second connector, 25 swing usefulness, and swing axial region 30 can be swung freely with the swinging mounting portion 33 on second lower cover 32 and is connected because of sandwiching second loam cake 31 that is located at formation second connector 25.Again, the connecting portion 28 that is connected with bellows 26 is also fixed because of sandwiching second upper member 31 and second lower member 32 that constitute second connector 25.
At the left and right sides of second loam cake 31 and lower cover 32, in the scope of not overslaugh bellows 26 swings, set wall with gap again.
The lead of handling in connecting portion 10 15 is set at first connector 24 is comprised swing part 27 and swings axial region 30 between interior first loam cake of cutting apart up and down 34 and first lower cover 35, handles in this space.Particularly on swing axial region 30, form on first loam cake 34 from swing axial region 36, form main swing axial region 37 on first lower cover 35, main swing axial region 37 is greater than from swing axial region 36, and, in main swing axial region 37, form groove by lead 15 (maintenance).Again, the terminal 38 that the lead 15 that exposes from swing axial region 30 sides of first connector 24 will be located at wire termination is fixed on the connecting portion 28 of bellows 26, from swing axial region 30 to keeping by the rib that is located on the lower cover 32 between the terminal 38.
Like this, because the lead 15 in the connecting portion 10 can be handled by carrying out distribution in the swing axial region 30 that is divided into first, second connector 24,25 up and down respectively, therefore, not only handle easily, and the bending that produces can reduce first connector 24 and the swing of second connector 25 time, alleviate the burden that causes because of swing, improve durability lead 15.
Again, aspect the lead of in connecting portion 10, handling 15, also have by about swing axial region 30 with being divided into the method for the left and right sides in first, second connector 24,25, handle (Fig. 5) but concentrate on a side, be convenient to assembling, can further eliminate the phenomenon that lead 15 is nipped.
Action to above structure describes.In case to body of dust collector 1 energising, then electric blowing machine 3 revolutions, the dust that sucks from inhalator body 9 passes through the prolongation pipe 7 and the flexible pipe 4 that are connected with connecting portion 28 again and is attracted to body of dust collector 1 by connecting the bellows 26 of first connector 24 and second connector 25.
At this, because swing second connector 25 freely is connected with first connector 24, and prolongation pipe 7 by being connected with second connector 25, the torsion action of handle 5 is passed to inhalator 8, therefore, torsion action by handle 5 is that the center makes handle 5 revolutions with the central shaft of handle 5 promptly, and when prolonging pipe 7 swings, the angle that prolongation pipe 7 and first connector 24 is formed changes.
When prolonging pipe 7 swings, utilize the swing of first connector 24, with the state that maintains below the inhalator body 9 towards swept surface, the angle that prolongs 24 formation of pipe 7 and first connector changes and causes 25 swings of second connector, therefore, equally can be with the state that maintains below the inhalator body 9 towards swept surface.
And,, the angle that prolongs 24 formation of pipe 7 and first connector is changed because 25 swings of second connector are freely, therefore, the swing of inhalator body 9 can be strengthened, for example, length direction (left and right directions) almost parallel of the axial and haustorium body 9 that prolongs pipe 7 can be made.
In this occasion, the hunting range of second connector 25 must can be swung before arriving plumbness at least under the state that inhalator body 9 is on the swept surface, in addition, prolong the axially parallel of pipe 7 for making with swept surface, inhalator body 9 can be swung before arriving level at least being under the state of swept surface, and, the hunting range of first connector 24 can swing from the state that does not apply torsion at handle as yet more than 90 degree by being formed, length direction (left and right directions) almost parallel of the axial and inhalator body 9 of prolongation pipe 7 can be made, and the axial and swept surface keeping parallelism that prolongs pipe 7 can be made.
Thus, can be reduced to parallel with swept surface substantially state because of prolonging pipe 7, so even the lower part of following equal altitudes of bed also can be cleaned, again because prolongation pipe 7 is parallel with inhalator body 9 length directions (left and right directions), therefore, the width narrow space also can clean, and can clean in wide scope.
As Fig. 4 and shown in Figure 7, on the dome portion of intermediate member 22, be provided with rectangular flange 39 at downside along first connector, 24 rotation directions for being slidingly connected from the lead 15 of connecting portion 10 with lead 15, thus, can prevent that lead 15 from causing the contact of 15 swing parts 27 of lead away from joint face (because of upwards pushing of flange 39) and nip, and can guarantee security.
As shown in Figure 6; first lower cover 35 is being arranged in the form that wire-protecting wall 40 that the downside of lead 15 outlets of drawing from connecting portion 10 will forwards protrude overlaps with intermediate member 22 with the front of the joint face of first connector 24; when swing lead 15; wire-protecting wall 40 is followed the action of lead 15 all the time with guardwire 15; thus; even to use back connecting portion 10 to occur loosening long-term, also guardwire 15 reliably.
Again owing to adopt transparent material in the material of intermediate member 22, therefore, by from the suction inlet of lower member 20, observing, the lead 15 during available Visual Confirmation assembling whether nipped or lead 15 whether at regular event.And, since on inhalator body 9 a facial part of exposing intermediate member 22, therefore, can confirm to turn round the revolution situation of brush 13 etc.
Present embodiment is connected first connector 24 by bellows 26 with second connector 25, but also first connector 24 and second connector 25 directly can be swung being connected freely, in case leak-stopping gas.

Yet, in above-mentioned structure, the structure freely because connecting portion 58 that constitutes flexible pipe 4 body of dust collector 1 by first connector 55 and second connector 56 bellows 57 through than flexible pipe 4 softnesses, also not being wound with piano wire 43 fascinates, therefore, available littler power than curved spout 4 is carried out bending to connecting portion 58.Thereby, when changing the direction of body of dust collector 1, can alleviate the burden that is applied on the handle 5, the usability when improving cleaning along left and right directions.
(embodiment 4)
Figure 13 is the central cross sectional view of the electric dust collector of the embodiment of the invention 4 with inhalator.The identical symbol of mark on the member identical with embodiment is to its detailed description of incomplete structure that had illustrated.
As shown in the figure, be installed on first connector 24 and connected bellows 26 parts at inhalator body 9 rear portions freely in swing, from first connector, 24 1 ends pack into thinner than the wall in this flexible pipe, and at one end be provided with the straight tube 64 of flange part 63, the other end of straight tube 64 extends to the position that surmounts first connector 24 and bellows 26 coupling parts.And, do not hinder the action of fascinating of bellows 26 in order to make the straight tube 64 that is assembled in this flexible pipe, as shown in the figure straight tube 64 axially carried out oblique cutting.The flange part 63 of the straight tube 64 that will pack into is thus clamped between by the inhalator body 9 and first connector 24 and straight tube 64 is deviate from.In addition, as shown in the figure,, the straight tube 64 in the bellows 26 of packing into is contacted with wrinkle portion even second connector 25 produces about 90 fascinating of position of degree and makes bellows 26 bendings.
Adopt said structure, from the below inhaled air of inhalator body 9 after right-angle bending slightly during by first connector 24 and bellows 26, at the collision sound that takes place at the jog of bellows 26, by the straight tube 64 of packing in this part, can reduce noise with regard to can because of air collides the sound taking place at the wrinkle jog of above-mentioned sweep.Though in the coupling part of the bellows 26 and first connector 24 as the pipe portion that is provided with some straight shapes in bellows 26 sides and when forming the concaveconvex shape of wrinkle shape from this pipe portion rear, can obtain same effect, but in this occasion, when 90 degree that produce second connector 25 move with interior fascinating, can strengthen the damage of the wrinkle jog of bellows 26 upsides, thus, can make the action of fascinating stiff and hinder its usability.
Again, as shown in figure 14, do not use the straight tube 64 of said structure, and change into pack the crooked back of sheet material 65 into bellows 26 along the inner face of the first half of bellows in, even this occasion, from the below inhaled air of inhalator body 9 after right-angle bending slightly during by first connector 24 and bellows 26, because bending to the air of approximate right angle flows along the upper wall (the crooked inner face of sheet material 65) in the pipe near the connecting portion of first connector 24 and bellows 26, therefore, the same with above-mentioned straight tube 64, the friction sound of the wind that takes place because of collision can be restrained, noise can be reduced thus to the wrinkle jog of bellows 26.
Though the said structure explanation is the connecting portion 10 of inhalator 8, but the flexible pipe portion of the connecting portion 45,58 of explanation has same effect by having adopted same structure among the embodiment 2,3, and, even the inhalator body 9 of dress drive motors also can obtain identical effect in non-.
Again, except attracting path, the present invention also be applicable to flexible pipe 4, have handle 5 pipe, prolong and be formed with the circulation type electric dust collector of exhaust channel that imports the exhaust of electric blowing machines 3 to inhalator 8 in the pipe 7.
From above-mentioned explanation as can be seen, electric dust collector of the present invention with the connecting portion of inhalator be by first connector of installing freely with the joint face swing of inhalator body relatively with the swaying direction approximate right angle direction of described first connector on second connector connection that is connected freely of swing, perhaps further be formed by connecting again by having flexual bellows, therefore, inhalator is being positioned under the state of swept surface, by twisting action to handle, the relative swept surface of inhalator can be done the swing of wide scope, make the prolongation pipe be parallel to swept surface, and make the inhalator body parallel with the prolongation pipe, even the width narrow space also can clean below barriers such as desk and bed.By (in inner space and the swing axial region etc.) sets lead in the inside of first connector and second connector, can improve the durability that connecting portion is swung again.
Again because the handle of electric dust collector and the connecting portion of flexible pipe are to swing first connector of installation freely and second connector that relative first connector fascinates constitutes by the relative joint face with handle, and first connector is connected with second connector by having flexual bellows, therefore, usually with the operation of the cleaning operation of push-and-pull before and after the handle and left and right directions moving handle the time, because of the connecting portion place of handle and flexible pipe has reduced bending, so moment diminishes, can reduce to be applied to the burden of handle portion, improve the cleaning operability.
Again because the connecting portion of the hose end that connects with flexible pipe is to be made of first connector and second connector that fascinates of relative first connector freely of swing on the joint face that is loaded on described body of dust collector, and first connector is connected with second connector by having flexual bellows, therefore, elongating flexible pipe and when left and right directions moves body of dust collector, because of having used flexible pipe, so can reduce the power of crooked usefulness at connecting portion.Thereby the burden in the time of can reducing body of dust collector and move improves body of dust collector mobility on the ground.
Again owing in the flexible pipe of the wind upside of above-mentioned bellows, be provided with straight tube or crooked sheet material, therefore, can restrain the friction sound of the wind that takes place because of collision to the wrinkle jog of bellows, can reduce noise.
