Extension spray lance 4 is by chimeric slidably vertically each other major diameter extension spray lance 10 and minor diameter extension spray lance 11, and the tube connector 12 that joins with floor suction filter 3 that is connected to minor diameter extension spray lance one end constitutes.Major diameter extension spray lance 10 and tube connector 12 are made by synthetic resin; Minor diameter extension spray lance 11 is made of metal, and makes as metal squash type drawing moulding fraction.
As shown in figure 11, the spaced walls 13 of available and minor diameter extension spray lance 11 global formations forms vertically and sucks distribution that path 14 separates fully and receive and adorn path 15.The minor diameter extension spray lance can have any section shape, and as shown in Figure 11, the section shape of minor diameter extension spray lance 11 is that distribution receipts dress path 15 has outwards been given prominence to about half from outer peripheral face; Or as shown in figure 12, dress path 15 is received in being shaped as at the inboard distribution that forms of pipe of minor diameter extension spray lance; Or as shown in figure 13, distribution is received dress path 15 and is all projected to the outside from minor diameter extension spray lance outer peripheral face.
Especially,, when it and major diameter extension spray lance 10 are chimeric, have and stop the effect of rotating,, can simplify whole extension spray lance structure owing to no longer needing to establish in addition other mechanism if adopt distribution to receive dress path 15 for from managing the outwards outstanding section shape of side face.In addition, compare with circular section, it can increase section coefficient, so can increase the intensity of pipe itself; If adopt the whole spaced walls 13 that forms of metal material, also can make its slimming.
The 16th, receive a pair of naked electric conductor that dress path 15 first halves dispose vertically at distribution, they are maintained at section and are in two grooves 18 of bar-shaped insulating element 17 of font.There is costal margin 38 both sides of this insulating element 17, they be formed at the engagement groove 19 that distribution receives on 15 two sides of dress path vertically and cooperate, can lead by this engagement groove, insert in the described path 15 with its end.Convex costal margin 20 between insulating element 17 2 grooves is used to guarantee the face insulation distance of 16 of a pair of electric conductors.Being positioned at that distribution receives when engagement groove 19 on dress path 15 two sides can utilize shaping minor diameter extension spray lance is all thick recess that becomes of installation root that makes spaced walls 13 two ends and minor diameter extension spray lance 11.
If, electric conductor can be directly arranged in distribution and receive in the dress path to make the minor diameter extension spray lance such as resin material without metal material, no longer need insulating element.As Fig. 9 and shown in Figure 10, the connector 21 of convex shell clamping fixedly is embedded in the tube connector tip side that distribution is received dress path 15, and link to each other with lead 22 between the electric conductor 16.On the other hand, be provided with connector 23 in the tube connector 12, the matrix housing clamping that joins by convex connector 21 with minor diameter extension spray lance 11; Described matrix connector 23 joins with the terminals 25 that are connected floor suction filter 3 through lead 24.So present embodiment is interpreted as a pair of electric conductor 16 and keeps their insulating element 17, and connector 21,23, lead 22,24 and terminals 25 constitute the power pack of minor diameter extension spray lance one side together.
The formation of major diameter extension spray lance 10 power packs below is described.One end of major diameter extension spray lance 10 is the thinner shape of front end that can join with hand-held handle 6; The end outer peripheral face is equipped with sealing gasket 26.27 for being located at the bar-shaped distribution supporter of major diameter extension spray lance 10 inboards, its length is received dress path 15 with the distribution of minor diameter extension spray lance 11 and is equated substantially, it is made of the cover plate 30 of maintenance body 29 that described groove 28 is arranged on it and covering groove 28, and electric wiring 31 is contained in the groove with insulating.Electric wiring 31 extends to the leading section that keeps body 29 always, at this place and be with flexible contact panel 32 to join; On the other hand, join with the termination 33 that is connected that is located at hand-held handle 6 one sides of major diameter extension spray lance.
One end of distribution supporter 27 is fixed on the major diameter extension spray lance 10, and the other end slidably inserts the Lower Half that distribution is received dress path 15.That is to say,, just can assemble distribution supporter 27 and insulating element 17 can keeping place, body 29 two sides convex costal margin 34 that forms and the mode that the insulating element 17 inboard grooves 35 that form combine by free slip mode.In this case, each contact panel 32 contacts slidably with the surface of each electric conductor 16, keep being electrically connected therebetween, thus the power pack of formation major diameter extension spray lance.Liner 36 is used to seal the opening portion of the distribution supporter 27 that inserts distribution receipts dress path 15; It is fixed on holding member 37 and the minor diameter extension spray lance 11.
For the electric cleaning device of structure like this, if need to change the length of extension spray lance 4, prolong extension spray lance as need and use corresponding to operating position, can be to minor diameter extension spray lance 11 application of forces, the direction of power system is along with its direction of extracting from major diameter extension spray lance 10.Meanwhile, with the reverse move operation body 41 of another hand along direction shown in the arrow among Figure 14, pressurized lever 49 along same direction shift action plate 44, compression face 48 is positioned at outside the relative position with combination 43, and combination 43 is dropped on outside the coupling recess 41 of minor diameter extension spray lance 11 by deadweight.So, minor diameter extension spray lance 11 and intervalve 45, and major diameter extension spray lance 10 between become free state, thereby it is extracted.
Then, decontrol operating body 41 when extracting minor diameter extension spray lance 11 to suitable length, rely on spring 79 to make action plate 44 reply initial positions, and with combination 43 be pressed into the minor diameter extension spray lance 11 corresponding with this compression face 48 in conjunction with in the recess 41.Like this, promptly can combination 43 restriction intervalves 45 moving vertically, thereby extension spray lance 4 is fixed as Len req.
