In Fig. 1, reference number 37 is a ground mobile model electric dust collector, be provided with the suction inlet parts 2 that are used to attract dust and can with suction inlet parts 2 mounting or dismounting suction nozzle 3 freely.Suction nozzle 3 is installed in the front end of extension pipe 32 in freely mode of mounting or dismounting, and extension pipe 32 connects mutually with handle handrail 34.Flexible pipe 36 1 ends and described handle handrail 34 link, and the other end links through hose coupling 35 and dust collector host body 37.
In addition, suction inlet parts 2 and suction nozzle 3 both can be contained in the dust that attracts swept surface under the state on the suction inlet parts 2 at suction nozzle 3, also can operating pedal 4 be attracted the dusts of swept surfaces under the state that suction nozzle 3 is pulled down from suction inlet parts 2 separately by suction nozzle 3.The dust that sucks is sent in the collecting unit of dust (not shown) that is located in the described dust collector host body 37.
In Fig. 2～8, pipe 5 by linking arm 7 with can rotate up and down freely mode and the rear portion of suction nozzle 3 link, the other end of pipe 5 with mounting or dismounting freely mode and an end of extension pipe 32 link.Connecting pin 6 is arranged to from the upper surface of pipe 5 rearward outstanding, be used for from dust collector host body 37 to electric component (not shown) supply power power such as motor that is located at suction inlet parts 2 inside and luminous components, these connect pins 6 and are connected with extension pipe 32.In addition, linking arm 7 and the rear portion that can left and right sides free rotation mode be located at suction nozzle 3.
When suction nozzle 3 used separately, if also left-right rotation of linking arm 7, suction nozzle 3 was just swung to the left side or the right easily, and dust suction is got up and become inconvenient on the contrary.Therefore, the left and right side of suction nozzle 3 is provided with clamp 8, makes to make linking arm 7 keep the left and right sides motionless when suction nozzle 3 is used alone.It is outwards outstanding that the end face of clamp 8 is configured to not from about the suction nozzle 3 two side walls.In addition, pedal 4 has the structure that clamp 8 is pushed, in case clamp 8 is pushed into, the fixing of linking arm 7 promptly is disengaged, and suction nozzle 3 will be held (fixing) on suction inlet parts 2.
As shown in Fig. 4,5, a plurality of positions of the bottom surface of suction nozzle 3 are provided with support component 9, make swept surface directly not contact with the bottom surface of suction nozzle 3.Cutting fibrous flannelette that these support components 9 are made of the weaving cloth of superfine fibre and single mode form plants hair etc. and constitutes.
The place ahead of suction nozzle 3 is provided with towards the air entry 15 of below opening with towards the suction inlet 13 of the place ahead opening.10 be two near air entries 15 and the rotary body that parallels with the length direction of suction nozzle 3, be arranged to and can rotate freely.Two rotary bodies 10 rotate towards the center position of air entry 15 respectively.
The structure of rotary body 10 is adhesively fixed with the dust that is used for wiping, cleans swept surface and removes body 23 as shown in Figure 7 on the outer surface that slightly is matrix 24 cylindraceous of formation center bone lattice.Matrix 24 can by thermoplasticity and cementability preferably the ABS resin material wait and constitute.Dust is removed body 23 and is made of the cutting fibrous flannelette that fine fibre weaving cloth constitutes.In addition, dust is removed the effect that body 23 also plays the wind-engaging body, distinguished and admirable will rotate as turbine when blowing Buddhist being subjected to, thereby rotary body 10 is rotated, and its direction of rotation is removed the fiber lodging direction of the flannelette of body 23 and determined by constituting dust.In the present embodiment, in order to make the center position rotation of rotary body 10 towards air entry 15, flannelette is configured to roughly become 90 degree to lodge laterally from the center of air entry 15.
The middle body of matrix 24 is a hollow form, and the centre is inserted with the axis body 25 that constitutes rotating shaft, and axis body 25 is made by metals such as stainless steels.Axis body 25 is not directly to be fixed on the matrix 24, but is fixed in the bearing 26, and bearing 26 plays the effect that reduces resistance to sliding by frame for movement or material behavior.In the present embodiment, bearing 26 is made of ball bearing.In addition, also can as shown in Figure 8 axis body 27 be remained in the bearing of being made by the low resin material of resistances to sliding such as POM 28, also can play same effect.In the rotary body shown in Fig. 8 30, be located at the gap that is provided with between the bearing 28 at two ends, the left and right sides and the axis body 27 about 1.0mm.When being installed to rotary body 30 on the suction nozzle 3, the gap holding part part 29 that is made of pad etc. also to being set, thereby between the front and back vertical wall of the length direction of bearing 28 and air entry 15, forming certain clearance.
When rotary body 10 installs on the suction nozzle 3, bearing A22 is aimed at the cylindric groove A18 that is located on the suction nozzle 3, bearing B2 1 is aimed at Elliptical toroidal groove B19,1 pair of rotary body 10 is loaded onto.Equally also be provided with the supporting structure 17 that is used for block bearing A22, bearing B21 on the lid 11.
Bearing fixing parts 20 are guaranteed the gap about 0.3mm by being covered with the adjacent cylindric nappe 16 of each groove A18, groove B19 between the outer surface of the madial wall of nappe 16 and bearing fixing parts 20.
Operational circumstances in the above-mentioned formation is as follows.
When dust catcher 37 work, be located at the electric blower of dust catcher 37 inside
The (not shown) operation, thus the dust-absorbing airflows that pass air entry 15 and pass produced from rotary body 10 centres.At this moment, dust-absorbing airflow will collide with the flannelette fiber of rotary body 10, and rotary body 10 will rotate under the effect of blast.
In addition, twist on the outer surface of rotary body 10 the flannelette fiber roughly towards with perpendicular direction (direction opposite) lodging of axis body 25 with direction of rotation, dust-absorbing airflow begins to clash with rotary body 10 from the front end of the flannelette fiber of lodging, so the fiber of lodging will become the wind-engaging part, thereby can obtain very strong revolving force.In addition, owing to front end one side of dust-absorbing airflow from the flannelette fiber of lodging begins to clash with rotary body 10, therefore,, always can access revolving force as long as do not flow into dust-absorbing airflow from root one side of flannelette fiber.Best mode is, dust-absorbing airflow roughly flows in 45 ° the scope from left and right directions respectively with respect to the front end of described flannelette fiber.
At this moment, because bearing 26 is made of the very little parts of resistances to sliding such as ball bearing, therefore, even the dust storage chamber (not shown) in dust collector host body 37 has been filled dust, air quantity when the value at initial stage descends, also can keep about 50% rotating speed of initial stage rotary speed.Experiment shows that as long as the rotating speed of rotary body 10 is more than 3000 rev/mins, and is just enough for cleaning works such as wiping swept surface.If the initial stage air quantity is 2.0, the rotary speed of following initial stage of occasion that constitutes at bearing 26 usefulness ball bearings is about 10000 rev/mins.When air quantity descends, be 1.0 o'clock at minimum air quantity, rotary speed is about 3500 rev/mins.In addition, be under the occasion of the resin structure shown in Fig. 8 at bearing 28, air quantity is 2.0 o'clock, rotating speed is about 7000 rev/mins; Air quantity is 1.5 o'clock, and rotating speed is about about 3000 rev/mins.
From about clamp the bearing 28 of matrix 24 end face portion have the stop parts that prevent that rotary body 30 from sliding, when installing to rotary body 30 on the suction nozzle 3, these stop parts might bump with the wall portion of air entry 15, and the revolving force of rotary body 30 is significantly descended.Therefore, be inserted with gap holding part part 29 betwixt, make the wall of bearing 28 and air entry 15 not take place directly to contact; Even and gap holding part part 29 and bearing 28 some take place contact, in order not increase the resistance to sliding between them, gap holding part part 29 preferably also is arranged to and can be rotated freely on axis body 27.So, under the occasion that adopts ball bearing structure, can use in the wideer air quantity scope of amplitude, ease of use will be improved.
Also once mentioned above, be provided with the rotary body 10 of two same structures in the suction nozzle 3.Central axis L on the length direction of rotary body 10 is configured to length direction (fore-and-aft direction) almost parallel of suction nozzle 3, about the mutual direction of rotation of side by side two rotary bodies 10 opposite.By adopting such direction of rotation, dust is gathered to the center inside of air entry 15 on direction of rotation from the outside of suction nozzle 3, thereby carries out the dust suction operation with very high efficient.
In addition, be made of flannelette etc. because dust is removed body 23, therefore, they also can be dirty, so rotary body 10 needs cleaning termly, so that keep its wiping, clean effect.For this reason, lid 11 is provided with stop component 12, and when it being forwarded to " opening " direction, lid 11 just can slide, and removes from suction nozzle 3.Next, catch the dust of rotary body 10 to remove body 23, rotary body 10 is pulled outward from air entry 15, just rotary body 10 can be pulled down respectively.Then, when after cleaning is finished, rotary body 10 being refilled, at first to see the shape of bearing A22, bearing B21 clearly, make its respectively be located at suction nozzle 3 on the corresponding back of groove A18, groove B19 installing, so just can be not the installation direction of rotary body 10 can be made a mistake.
In addition,, also put on corresponding color, just can be easy to examine installment state, thereby can improve the operation convenience when safeguarding by shape and color in suction nozzle 3 one sides if on bearing A22 and bearing B21, put on certain color.
In addition, under the occasion that the bearing 26 of the axis body 25 of rotary body 10 is made of ball bearing, come off in order after rotary body 10 is pulled down from suction nozzle 3, axis body 25 to be unlikely, be provided with the anti-drop device that withstands the interior wheel of ball bearing from the inboard, can improve the property easy to maintenance of rotary body 10 like this.
In addition, if when the long fibre dust is wrapped near the root of bearing 26 and axis body 25, can oppress the interior wheel of bearing 26 (that is ball bearing), the performance of infringement ball bearing rises resistance to sliding, may rotate the phenomenon of body 10 stalls.In order to prevent the generation of this situation, it is flange (not shown) about 1mm that the outer circumference surface of bearing fixing parts 20 is provided with width, forms the space with the gap about 0.3mm between the maintaining part 17 of its excircle and suction nozzle 3 and lid 11.By above-mentioned flange is covered, can make the long fibre dust can not arrive bearing 26 by the labyrinth effect, thereby can prolong maintenance period, can during very long, just need not to safeguard and can use always.But, because removing body, dust needs to be serviced after dirty, when pulling down rotary body 10, also just can carry out attended operation easily.
When suction inlet parts 2 and suction nozzle 3 are installed together, can be used as suction nozzle assembly 1 and use, given play to cleaning performance at carpet and the bigger place of floor homalographic.In general family, the place exists the situation in the gap about 50mm a lot of between the furniture etc.When these places are cleaned, suction nozzle need be pulled down usually, load onto in a narrow margin and just can carry out dust suction behind other suction nozzle spare parts such as suction nozzle.But, adopt present embodiment, as long as step on pedal 4, suction nozzle 3 and suction inlet parts 2 are broken away from, just can realize and suction nozzle identical functions in a narrow margin.
The width of suction nozzle 3 is set at about 50mm, the length direction almost parallel of rotary body 10 and suction nozzle 3.In addition, by support component 9 is set on lid 11, direct contacting structure does not take place with the bottom surface that makes swept surface and suction nozzle 3 and can realize with same parts in the structure that supports axis body, like this, suction nozzle 3 can be realized miniaturization, and a kind of suction nozzle main body 1 of serviceability excellence can be provided.
In addition, in the present embodiment,, can enlarge the scope of application on suction inlet parts 2 by the suction nozzle 3 that can freely install and remove is set.But, separately suction nozzle 3 is used as suction nozzle parts, also can reach same effect.
