[structure of air suction injection apparatus]
The concrete structure of the air suction injection apparatus 10A that this embodiment is related then, is described with reference to Fig. 2 to Fig. 5.
Shown in the side view of Fig. 2, the related air suction injection apparatus 10A of this embodiment possesses: main part 111, injection stream portion 112, bar member 113, unshowned fan portion, suction chamber and stream switching part in Fig. 2.In addition, shown in the side view of the stereogram of Fig. 3 and Fig. 4, can aspirate at air the suction nozzle 26A that front end possesses brush is installed on the injection apparatus 10A.
Main part 111 is roughly tubulose, and its inside is the primary flow path of air.The two ends of main part 111 are respectively front end opening 111a and the 111b of open rearward end portion; Front end opening 111a constitutes the roughly tetragonal peristome that suction nozzle 26A (perhaps other suction nozzle 26) can be installed, and the 111b of open rearward end portion constitutes the columnar peristome that can be installed on suction hose 22 (more specifically near body operating portion 23).Front end opening 111a and the 111b of open rearward end portion are preferably formed and are conical by its shape.Thus, easily suction nozzle 26A or suction hose 22 are installed on the periphery of front end opening 111a or the 111b of open rearward end portion or unload suction nozzle 26A or suction hose 22 from the periphery of front end opening 111a or the 111b of open rearward end portion.
Like Fig. 2 or shown in Figure 4, the position relation that injection stream portion 112 is set to tilt with the tube axial direction with respect to main part 111 forms as one with this main part 111.The inside of spraying stream portion 112 is the secondary flow road of air, and this secondary flow road constitutes with front end opening 111a and is connected.In addition, spray stream portion 112 and be provided with injection air introducing port 112a.
The state that air suction injection apparatus 10A is positioned at the top with injection stream portion 112 basically is installed on the nearly body operating portion 23 of suction hose 22 front ends.Thereby, in following explanation, will spray stream portion 112 sides of living in be called " on ", opposition side is called D score.In addition, a front end opening 111a side of living in is called " front end ", the 111b of an open rearward end portion side of living in is called " rear end ".
Like Fig. 2 or shown in Figure 4; Spray in the stream portion 112 and extend with the mode that the tube axial direction with respect to main part 111 tilts to the position that upside exposes from main part 111; As shown in Figure 3; Upper surface at this position is provided with discoideus position, is formed with injection air introducing port 112a at this discoideus downside.This injection air introducing port 112a is that to be used to pass air into the inside of spraying stream portion 112 be the opening on secondary flow road.
In addition,, promptly be positioned at the position of the opposition side that sprays stream portion 112, be provided with a plurality of suction forces adjustment hole 111c along the periphery of this main part 111 across main part 111 at the downside of main part 111.This suction force adjustment hole 111c is used for beyond front end opening 111a, atmosphere being taken into primary flow path, to avoid since front end opening 111a suction or adsorb dust etc. cause the primary flow path of main part 111 stop up and the inflow of air to become the burden that below the regulation flow electric dust collector is caused excessive.
Bar member 113 covers member 113c by changer lever 113a, bar support 113b and air importing and constitutes.Like Fig. 2 and shown in Figure 4, bar support 113b covers between the member 113c at changer lever 113a and air importing, and this bar support 113b is rotating shaft, is held with state that runs through main part 111 and the mode that can be rotated.In addition, of the back, on bar support 113b, the stream switching part is installed, 113a can carry out the switching of stream switching part through the operation changer lever.
As shown in Figure 3; Changer lever 113a is set to the frame shape of main body covered 111 downside, and air imports and covers member 113c is the tabular component that seals the suction air introducing port (not shown in Fig. 2 ~ 4) of the side that is arranged on main part 111 with the mode that can open and close.As shown in Figure 3, through elastic components such as springs changer lever 113a is applied distolateral forward power, so air imports and to cover member 113c and be located substantially on rear end side.And of the back, bar member 113 is that the center is rotated with bar support 113b, if therefore make changer lever 113a side shifting to the back-end, then air imports and covers member 113c forward end side shifting.At this moment, being imported the suction air introducing port (not shown in Fig. 2 ~ 4) that covers member 113c sealing by air is opened.In addition, when making changer lever 113a fully to the back-end during side shifting, the part of the downside of changer lever 113a and main part 111 connects and stops, thus air import cover member 113c can not surpass need the forward end side shifting.
Like Fig. 3 or shown in Figure 4, the suction nozzle 26A that is installed on the front end opening 111a of main part 111 comprises nozzle body 261 and front end brush 262.As shown in Figure 3, be provided with the pump orifice 261a that is used to aspirate dust etc. at the front end of nozzle body 261.In addition, in Fig. 3 or structure shown in Figure 4, front end brush 262 is folded the downside of nozzle body 261, but also can as after state such giving prominence to and be positioned at the front of pump orifice 261a.
Shown in the longitudinal section of Fig. 5, have: the primary flow path 101 that constitutes by the inside of main part 111, the secondary flow road 102 that constitutes by the inside of spraying stream portion 112 and at the downside that sprays stream portion 112 and towards the suction chamber 115 of primary flow path 101 in the set inside of air suction injection apparatus 10A.It is adjacent to each other and form as one to spray stream portion 112 and suction chamber 115, and portion is provided with fan portion 114 within it.In other words, spraying stream portion 112 is fan portion resettlement sections with suction chamber 115, and suction chamber 115 is power fan resettlement sections.In addition, the position towards primary flow path 101 in suction chamber 115 is provided with internal suction mouth 115a, and of the back, also is provided with the suction air introducing port 115b that is connected with the outside of main part 111.
Fan portion 114 comprises and is positioned at the injection fan 114a that sprays stream portion 112, is positioned at the power fan 114b of suction chamber 115 and the rotating shaft 114c of rotatably mounted these fans.Spray fan 114a and in secondary flow road 102, form the jet-stream wind that flows to front end opening 111a.Power fan 114b constitutes and sprays fan 114a common fan rotating shaft 114c, therefore is rotated linkedly with this injection fan 114a.In addition, about the concrete action of fan portion 114, with after the formation of the jet-stream wind stated describe.
As stated, primary flow path 101 is made up of main part 111 and the inside of spraying stream portion 112 respectively with secondary flow road 102, and is as shown in Figure 5, in the position primary flow path 101 and 102 interflow, secondary flow road of the front of primary flow path 101.From front end opening 111a, the direction that primary flow path 101 (main part 111) is advanced along straight is extended, and secondary flow road 102 primary flow path 101 midway to these primary flow path 101 acutangulate direction bifurcateds.If be not that benchmark shows this state and be that benchmark shows this state with main part 111 with spraying stream portion 112, then spray stream portion 112 so that collaborate with the primary flow path 101 of the inside of main part 111 on its inner secondary flow road 102 on this main part 111, being provided with primary flow path 101 and secondary flow road 102.In addition, because secondary flow road 102 and primary flow path 101 interflow, so the front end opening 111a double as of main part 111 sprays the jet of stream portion 112.
The position of collaborating on primary flow path 101 and secondary flow road 102 in addition, is provided with stream switching part 116.As long as stream switching part 116 constitute at least to secondary flow road 102 and front end opening 111a be connected and disconnection is switched; In this embodiment for following structure: choose the switching of one of which, make to be connected primary flow path 101 perhaps with front end opening 111a secondary flow road 102 is connected with front end opening 111a.
Specifically, as shown in Figure 5, stream switching part 116 is roughly tabular valve member, and an end is fixedly supported upon on the bar support 113b.Thereby through operation changer lever 113a, stream switching part 116 is that fulcrum is swung in the zone at position, interflow with bar support 113b.Therefore, can change the pendulum angle of stream switching part 116 freely through operation changer lever 113a.
At this; As with such shown in the zone that dotted line surrounded of Fig. 5; If the position, interflow in the primary flow path 101 is defined as " main body interflow mouthful 111d "; Position, interflow in the secondary flow road 102 is defined as " spray interflow mouthful a 112b ",, changes angles (swing) with the perhaps side in the secondary flow road 102 of sealing primary flow path 101 as the stream switching part 116 of valve member then through operation changer lever 113a.In addition, in structure shown in Figure 5, stream switching part 116 is in the state that sprays interflow mouthful 112b that sealed.
In addition, be rocked to position, be used to retainer 111e, 112c that moving of stream switching part 116 stopped at the assigned position place with spraying all to be provided with among mouthful 112b of interflow at main body interflow mouthful 111d above closed state for fear of stream switching part 116.These retainers 111e, 112c are the outstanding projections of internal face of perhaps spraying stream portion 112 from main part 111; The wire projection that in structure shown in Figure 5, is complementary for shape with stream switching part 116; But being not limited to this structure, also can be the projection of other shape.
The concrete structure that the related air of this embodiment is aspirated injection apparatus 10A and suction nozzle 26A does not limit especially, and main part 111, injection stream portion 112, bar member 113, fan portion 114, suction chamber 115 and stream switching part 116 etc. are so long as use the structure that known member, material, shape etc. can produce in the perhaps bigger household appliances field, electric dust collector field to get final product.
[action of air suction injection apparatus]
Then; Except Fig. 5, also come to explain particularly the action of the air suction injection apparatus 10A with said structure, particularly from the switching between the details of the function (blowing function) of pump orifice 261a spray air-flow and this blowing function and the common pumping function (vacuum cleaning function) with reference to Fig. 6 to Figure 10.
At first, for example shown in Figure 6, air suction injection apparatus 10A can directly be installed on the nearly body operating portion 23 that is arranged on suction hose 22 front ends and use.That is to say that the user prolongs in suction and unloads suction under the state (with reference to Fig. 1) that pipe 24 and section port body 25 be installed on nearly body operating portion 23 and prolong pipe 24, air is installed with replacing is aspirated injection apparatus 10A, uses with this state.In addition, suction nozzle 26A is installed (with reference to Fig. 3 ~ Fig. 5), the action of air suction injection apparatus 10A is described based on this state also in following explanation on air suction injection apparatus 10A.
Then, common vacuum cleaning function is described.As shown in Figure 5, in air suction injection apparatus 10A, changer lever 113a is in the constant state that is positioned at front, and therefore at the interflow position of primary flow path 101 with secondary flow road 102,116 sealings of stream switching part are sprayed interflow mouthful 112b and opened main body interflow mouthful 111d.And when the action through main body of dust collector 21 (not shown in Fig. 5) produced suction force, this suction force arrived primary flow path 101 and suction nozzle 26A via suction hose 22 (not shown in Fig. 5).Therefore, shown in the thick-line arrow among the figure,, in primary flow path 101, form from the suction airstream of front end opening 111a towards the 111b of open rearward end portion from pump orifice 261a suction atmosphere.
Then, switching to blowing function is described.As shown in Figure 7, when the user made the changer lever 113c operation of side shifting to the back-end, air imported and cover member 113c forward end side shifting, was therefore imported by air and covered the suction air introducing port 115b that member 113c seals and be opened.And as shown in Figure 8, at the interflow position of primary flow path 101 with secondary flow road 102, stream switching part 116 sprays the position that the position of collaborating mouthful 112b moves to sealing main body interflow mouthful 111d from sealing.Thus, spray an interflow mouthful 112b and be opened, so secondary flow road 102 is connected primary flow path 101 and front end opening 111a disconnection with front end opening 111a.Shown in thick-line arrow among the figure, near the suction force that the 111b of open rearward end portion, produces pump orifice 115a is internally aspirated suction chamber 115 inner air.
At this moment, shown in Figure 9 to what look like the direction of the arrow I of double dot dash line from Fig. 8, the suction air introducing port 115b that is opened is connected with suction chamber 115, so the inside of suction chamber 115 is connected with atmosphere.Therefore, formation is towards the suction airstream of suction air introducing port 115b, suction chamber 115, internal suction mouth 115a.This suction airstream flows to suction hose 22 (not shown among Fig. 8, Fig. 9) via primary flow path 101 from the 111b of open rearward end portion.And at the dynamic fan 114b of the set inside of suction chamber 115, so this power fan 114b is rotated under the effect of suction airstream.More specifically; If owing to the suction airstream that produces in the primary flow path 101 causes this primary flow path 101 decompressions; Then the also directly decompression of the inside of suction chamber 115 owing to this decompression forms a large amount of suction airstream from suction air introducing port 115b towards internal suction mouth 115a.Thus, power fan 114b is rotated in the inside of suction chamber 115.
And, because power fan 114b and injection fan 114a common fan rotating shaft 114c therefore along with the rotation of power fan 114b, spray fan 114a and also are rotated.Spray fan 114a and be arranged on and spray in the stream portion 112, therefore shown in the thick-line arrow of Fig. 8, in secondary flow road 102, form jet-stream wind, this jet-stream wind flows to the inside of suction nozzle 26A from front end opening 111a, and ejects from pump orifice 261a.
In addition, if the user removes the state that changer lever 113a moves to rear end side, then changer lever 113a is back to original position from rear end side forward end side shifting.Follow this to return, air imports and covers member 113c closed-suction air introducing port 115b, and stream switching part 116 moves to the position of opening main body interflow mouthful 111d from opening the position of spraying interflow mouthful 112b.Therefore, secondary flow road 102 is broken off with front end opening 111a, and primary flow path 101 is connected with front end opening 111a, thus power fan 114b with spray fan 114a and stop the rotation, also stop from the jet-stream wind of pump orifice 261a injection.In addition, in primary flow path 101, form suction airstream, therefore produce suction force once more at pump orifice 261a.
Like this, in this embodiment, only switch stream switching part 116, just can eject jet-stream wind from front end opening 111a through operation changer lever 113a.Therefore, when using electric dust collector 20, need not to use complicated structure just can easily eject jet-stream wind from suction nozzle 26A front end.In addition, only make changer lever 113a recovery just can stop blowing function and be back to the vacuum cleaning function, therefore not only operability improves, and can also come suitably to switch vacuum cleaning function and blowing function according to the behaviour in service of electric dust collector 20.
If can easily switch vacuum cleaning function and blowing function; Then for example can be back to the vacuum cleaning function immediately after the dust of cleaning on the object blows afloat will being deposited in through blowing function, the dust that is flown upward blowing afloat promptly aspirated it before indoor diffusion.The position that for example is difficult for for the user seeing in (1) or the cleaning of high position, (2) attached to swept surface or be deposited in the jog the inside dust cleaning and (3) when pump orifice near the time might produce breakage, do not expect move, under the situation of the cleaning of the object of maloperation, mistake suction etc., can suitably utilize this cleaning method.
In addition, under the situation of the cleaning of carrying out above-mentioned (3),,, blow out jet-stream wind and might make this dust with needing above dispersing then according to the differences such as kind of object or dust if the imposing manner of jet-stream wind is fixed.At this, in this embodiment, be following structure as the stream switching part 116 of valve member: the operation according to changer lever 113a changes angle, seals another stream to open a stream in primary flow path 101 and the secondary flow road 102.Therefore, if for example do not make changer lever 113a move to rear end side fully and remain on midway, then can form jet-stream wind and suction airstream simultaneously.
Thereby, through the mode of operation of adjustment, can change the ratio of jet-stream wind and suction airstream freely to changer lever 113a, can apply the appropriate jet-stream wind of flow to object.In addition,, can finely tune, therefore can finely tune blowing function to the flow of jet-stream wind through the mode of operation of adjustment to changer lever 113a.
And the injection fan 114a that forms jet-stream wind is along with power fan 114b is rotated, and this power fan 114b is owing to the suction airstream that is formed in the primary flow path 101 is rotated.Therefore the air-flow through the primary flow path 101 of flowing through can make injection fan 114a be rotated, and therefore need not be provided with and use the drive source of power supply that this injection fan 114a is rotated.Therefore, the structure of air suction injection apparatus 10A can be simplified, in addition, the increase of cost can be avoided.
In addition, shown in figure 10, even outstanding and be positioned under the state of front of pump orifice 261a, also can as above-mentioned, suitably switch vacuum cleaning function and blowing function at the front end brush that makes suction nozzle 26A 262.Promptly; Shown in figure 10, if make changer lever 113a side shifting to the back-end, then suction air introducing port 115b is opened; Therefore be taken into air from suction air introducing port 115b to suction chamber 115, form the big suction airstream of flow towards internal suction mouth 115a from suction air introducing port 115b.Thus, suction chamber 115 inner power fan 114b are rotated strong, therefore can form the big jet-stream wind of flow velocity through spraying fan 114a.

And stream switching part 126 was swung and was sealed main body interflow mouthful 121d as stated this moment, therefore, sprayed the state that opening adjustment plate 121f becomes inclination.Therefore, reduce owing to injection opening adjustment plate 121f sprays aperture area, therefore the jet-stream wind from secondary flow road 102 ejects from pump orifice 121g with the state that flow velocity increases.
In addition, shown in Figure 15 (and Figure 14), be positioned at changer lever 123a under the state of rear end side and lock, therefore, just can go out jet-stream wind by sustained firing as long as do not remove this lock-out state by the 127 couples of changer lever 123a in lever lock bonding part.And if the user has removed the locking of 127 couples of changer lever 123a of rod lock portion, then changer lever 123a is back to original position from rear end side forward end side shifting.
Along with this returns; Air imports and covers member 123c closed-suction air introducing port 125b; Stream switching part 126 moves to the position of opening main body interflow mouthful 121d from opening the position of spraying interflow mouthful 122b, and sprays opening adjustment plate 121f and be back to the contacted state of lower inner surface with front end spray nozzle part 121a from heeling condition.Therefore, secondary flow road 102 is broken off with front end spray nozzle part 121a, and primary flow path 101 is connected with front end spray nozzle part 121a, thus power fan 124b with spray fan 124a and stop the rotation, also stop from the jet-stream wind of pump orifice 261a injection.In addition, in primary flow path 101, form suction airstream, therefore produce suction force once more at pump orifice 261a place.
Like this, in this embodiment, front end opening becomes front end spray nozzle part 121a, therefore can replace common suction nozzle (for example suction nozzle 26A, 26B etc.) and use air suction injection apparatus 10B.Therefore; For example shown in Figure 16; Can replace suction nozzle and in advance air aspirated the downside that injection apparatus 10B releasably is installed on nearly body operating portion 23; When the needs blowing function, can unload suction from nearly body operating portion 23 and prolong pipe 24 (not shown among Figure 16) and air suction injection apparatus 10B is installed.
In addition, in this embodiment, be provided with lever lock bonding part 127, therefore can be with the locking position of changer lever 123a position at blowing function.Therefore, can easily continue the performance blowing function, and, can easily be back to the vacuum cleaning function through unlocking.And; In the set inside of front end spray nozzle part 121a injection opening adjustment plate 121f; Therefore air suction injection apparatus 10B can be used as common suction nozzle when vacuum cleaning; Reduce and spray aperture area, therefore can improve the flow velocity of jet-stream wind when pump orifice 121g ejects, strengthen the imposing manner of jet-stream wind in when blowing.
In addition; In this embodiment; As the member that reduces to spray aperture area (spraying opening adjustment member), used tabular injection opening adjustment plate 121f, but the present invention is not limited thereto; So long as when blowing, can reduce the member of the aperture area of peristome (in this embodiment, being pump orifice 121g), can use known various member as " jet ".And, spray opening adjustment member and also can constitute and be not only the flow velocity that is used to improve jet-stream wind and strengthen imposing manner, on the contrary, also spray aperture area and reduce flow velocity to weaken imposing manner through increasing.That is to say, as long as spray the imposing manner that opening adjustment member can be adjusted jet-stream wind.
And; In this embodiment; Spraying opening adjustment plate 121f constitutes through the front end of stream switching part 126 and the rear end butt of this injection opening adjustment plate 121f to tilt to reduce to spray aperture area; But the present invention is not limited thereto, and also can constitute the action interlock with bar member 123, can also be only can not change the structure at the angle of inclination of spraying opening adjustment plate 121f with interlock such as other member.
In addition, in this embodiment, front end spray nozzle part 121a does not possess additional member, but for example can as the suction nozzle 26A in the above-mentioned embodiment 1,26B, possess front end brush 262 etc. yet.And, the prolongation nozzle that the shape with front end spray nozzle part 121a is complementary can also be installed.
(embodiment 3)
The structure of the air suction injection apparatus that embodiment of the present invention 3 is related is identical with the related air suction injection apparatus 10B of above-mentioned embodiment 2 basically; Greatly different points are; The front end opening of main part is the front end spray nozzle part of nozzle-like, but further in the inside of this front end spray nozzle part, primary flow path is separated with the secondary flow road fully; And, not above-mentioned stream switching part but be provided with the passage opening/closing portion that opens and closes primary flow path as spraying switching part.Come to explain particularly the air suction injection apparatus that this embodiment is related with reference to Figure 17 and Figure 18.
[structure of air suction injection apparatus]
At first, like Figure 17 and shown in Figure 180, the related air suction injection apparatus 10C of this embodiment possesses main part 131, sprays stream portion 132, bar member 133, fan portion 134, suction chamber 135 and passage opening/closing portion 136.And, the main part 121 in main part 131 and the above-mentioned embodiment 2 likewise, two ends are front end spray nozzle part 131a and the 131b of open rearward end portion, are provided with a plurality of suction forces at the downside of main part 131 and adjust hole 131c.In addition, the suction chamber 135 that possesses internal suction mouth 135a and not shown suction air introducing port is arranged, with suction chamber 135 set inside fan portion 134 is arranged spraying stream portion 132 in the set inside of main part 131.
Injection stream portion 122 in injection stream portion 132 and the above-mentioned embodiment 2 likewise is provided with injection air introducing port 132a.In addition, the bar member 123 in bar member 133 and the above-mentioned embodiment 2 likewise comprises that changer lever 133a, bar support 133b and not shown air import to cover member.In addition, the fan portion 124 in fan portion 134 and the above-mentioned embodiment 2 likewise comprises and sprays fan 134a, power fan 134b and fan shaft 134c.
At this; For being arranged on the inner primary flow path 101 and secondary flow road 102 of air suction injection apparatus 10C; The air suction injection apparatus 10B related with the related air suction injection apparatus 10A of above-mentioned embodiment 1 or above-mentioned embodiment 2 is different, is separated fully.Therefore, do not have the position at the two interflow, also do not have the opening of the injection interflow mouthful 122b that is equivalent in the above-mentioned embodiment 2, be that the front end at front end spray nozzle part 131a is provided with jet 132b with replacing.On the other hand, the opening for being equivalent to the main body interflow mouthful 121d in the above-mentioned embodiment 2 is provided with main body and opens and closes a mouthful 131d.
As long as the pump orifice 131g that this main body switching mouthful 131d is arranged to than is positioned at front end spray nozzle part 131a front end is more near rear end side; And open and close a mouthful 131d in order to open and close main body, be provided with above-mentioned embodiment 2 in the identical passage opening/closing portion 136 of stream switching part 126.This passage opening/closing portion 136 is through only opening or breaking off primary flow path 101, comes the formation of the suction airstream at front end spray nozzle part 131a place and the formation of jet-stream wind are switched.
[action of air suction injection apparatus]
Then, the action of air suction injection apparatus 10C with said structure is explained particularly.At first; When common vacuum cleaning function is described, shown in figure 17, in air suction injection apparatus 10C; Changer lever 133a is in the constant state that is positioned at front, so passage opening/closing portion 136 contacts with the upper inside surface of main part 131 and opens main body and opens and closes a mouthful 131d.Then, such shown in the thick-line arrow among the figure,, form from the suction airstream of front end spray nozzle part 131a in primary flow path 101 from pump orifice 131g suction atmosphere through the suction force of electric dust collector 20 (not shown in Figure 17) towards the 131b of open rearward end portion.
Then, switching to blowing function is described.Shown in figure 18; When the user makes the changer lever 133a operation of side shifting to the back-end; Not shown suction air introducing port is opened, and passage opening/closing portion 136 is from moving to the position of sealing the main body switching 131d of portion with the contacted state of the inner surface of main part 131.Thus, can break off primary flow path 101, and such shown in thick-line arrow among the figure, and the suction force of primary flow path 101 pump orifice 135a is internally aspirated suction chamber 135 inner air.
As stated, suction chamber 135 is connected with atmosphere through not shown suction air introducing port, therefore forms the suction airstream towards suction air introducing port, suction chamber 135, internal suction mouth 135a.Therefore, be arranged on suction chamber 135 inner power fan 134b and under the effect of suction airstream, be rotated, spray fan 134a with it linkedly and also be rotated.Thus, shown in thick-line arrow among the figure, be to form jet-stream wind in the secondary flow road 102 spraying stream portion 132, this jet-stream wind only ejects from jet 132b, and this jet 132b is the front end of front end spray nozzle part 131a and is the front end that sprays stream portion 132.
Afterwards, if the user removes the state that changer lever 133a moves to rear end side, then passage opening/closing portion 136 opens main body and opens and closes a mouthful 131d, and not shown in addition suction air introducing port is imported by not shown air and covers the member sealing.Therefore, the suction airstream that forms towards suction air introducing port, suction chamber 135, internal suction mouth 135a disappears, power fan 134b with spray fan 134a and stop the rotation, the jet-stream wind that sprays from jet 132b also stops.In addition, in primary flow path 101, form suction airstream, therefore produce suction force once more at pump orifice 131g place.
Like this; In this embodiment; Spraying stream portion 132 directly is connected with front end spray nozzle part 131a; Therefore jet-stream wind is ejected from front end spray nozzle part 131a even do not switch especially, and if open main body through passage opening/closing portion 136 and open and close a mouthful 131d, then can in primary flow path 101, form suction airstream.Thereby, only through just can easily switch the blowing function and the vacuum cleaning function of electric dust collector as the switching of the passage opening/closing portion 136 of draught excluder member with simple structure.
At this, the aperture area of pump orifice 131g and jet 132b is not limited especially, so long as the area that can realize blowing function and vacuum cleaning function effectively is than getting final product.For example, can enumerate out following structure: the aperture area of pump orifice 131g is made as identical, makes the aperture area of jet 132b littler with the aperture area of common suction nozzle.If this structure; Then when vacuum cleaning, can easily aspirate dust, therefore can obtain the handy degree identical, when blowing with common suction nozzle from pump orifice 131g; Jet-stream wind ejects from littler aperture area, therefore can increase the flow velocity of this jet-stream wind.
In addition; In this embodiment; Suction airstream and jet-stream wind flow in diverse stream (primary flow path 101 with secondary flow road 102) respectively, are attached to the possibility that the dust on the inwall of primary flow path 101 ejects from secondary flow road 102 when blowing when therefore having avoided vacuum cleaning fully.Therefore, can make jet-stream wind become the more air-flow of cleaning from jet 132b.
In addition; In this embodiment; The basic structure of air suction injection apparatus 10C is identical with the basic structure that above-mentioned embodiment 2 related air aspirate injection apparatus 10B; Therefore, the position that main body opens and closes mouthful 131d and passage opening/closing portion 136 also with air suction injection apparatus 10B in the position, interflow on primary flow path 101 and secondary flow road 102 roughly the same, but the present invention is not limited thereto certainly; Can make suction chamber 135 inner pressure relieves at least if open and close a mouthful 131d through the sealing main body, then main body switching mouthful 131d and passage opening/closing portion 136 can be arranged on position arbitrarily.

At this moment, because suction air introducing port 145b is opened, so suction chamber 145 is inner is connected with atmosphere, and therefore formation is towards the suction airstream of suction air introducing port 145b, suction chamber 145, internal suction mouth 145a.Shown in figure 23, this suction airstream flows to suction hose 22 (not shown among Figure 23) via primary flow path 101 from the 141b of open rearward end portion.Then, be arranged on suction chamber 145 inner power fan 144b and under the effect of suction airstream, be rotated, spray fan 144a therewith linkedly and also be rotated.Therefore, shown in the thick-line arrow of Figure 23, be to form jet-stream wind in the secondary flow road 102 spraying stream portion 142, it is inner that this jet-stream wind flows to front end opening 141a, ejects from the pump orifice 261a of suction nozzle 26C.
Afterwards, if the user removes the state that changer lever 143a moves to rear end side, then stream switching part 146 is opened main body interflow mouthful 141d, and suction air introducing port 145b is imported by air and covers member 143c sealing in addition.Therefore, the suction airstream that forms towards suction air introducing port 145b, suction chamber 145, internal suction mouth 145a disappears, power fan 144b with spray fan 144a and stop the rotation, the jet-stream wind that sprays from suction nozzle 26C also stops.In addition, in primary flow path 101, form suction airstream, therefore produce suction force once more at suction nozzle 26C place.
Like this; It is roughly the same that the structure of the air suction injection apparatus 10D that this embodiment is related and above-mentioned embodiment 1 related air aspirate injection apparatus 10A; But as stated, front end opening 141a is the structure at interior all installation accessories, and its profile is bigger than main part 141.And, can know that according to the stereogram of Figure 19 the entire upper surface of spraying stream portion 142 forms cap-shaped, and is connected with the part of front end opening 141a.If this structure then as annex, is not only the annex of the light weight as common suction nozzle 26C,, also can install and supporting well for relative heavier annex.Therefore, for the user, can increase the kind of spendable annex.
In addition, in this embodiment,, used the suction nozzle 26C that possesses front end brush 262, but the present invention is not limited thereto, can suitably uses known various suction nozzle as the annex that is installed in air suction injection apparatus 10D.For example shown in Figure 24, can use relatively long suction nozzle 26D.Illustrative suction nozzle 26B (with reference to Figure 11) compares long enough in this suction nozzle 26D and the above-mentioned embodiment 1; Therefore; Weight is also big than suction nozzle 26B; But it is, easy to use concerning the user if the related air suction injection apparatus 10D of this embodiment then can stably keep installment state.
(embodiment 5)
It is identical that the related air suction injection apparatus of embodiment of the present invention 5 and above-mentioned embodiment 4 related air aspirate injection apparatus 10D; But difference is, the annex that is installed in front end opening 141a is not suction nozzle 26 but liquid spraying portion.Come to explain particularly the air suction injection apparatus that this embodiment is related with reference to Figure 25 and Figure 26.
[structure of liquid spraying portion]
Shown in figure 25, the front end opening 141a place at the related air suction injection apparatus 10D of this embodiment is equipped with liquid spraying portion 27 as annex.Liquid spraying portion 27 possesses liquid container 271, spray nozzle 272, liquid suction tube 273 and shutter 274.
At liquid such as liquid container 271 internal reservoir cleaning fluids, deodorant, aromatic.Spray nozzle 272 is used to spray the spraying of the liquid that is stored in liquid container 271 inside, and portion is provided with shutter 274 within it.Liquid suction tube 273 makes the inside of liquid container 271 be connected with spray nozzle 272, imports to spray nozzle 272 from liquid container 271.
Shutter 274 is fixed on the inwall of spray nozzle 272, can realize sealing spray nozzle 272 inside upright state and from the rear end side of spray nozzle 272 state of distolateral lodging forward.The position that is provided with to shutter 274 does not limit especially, but compares more near rear end side with the position that is connected with liquid suction tube 273 at least.In addition, the front end of spray nozzle 272 is the nozzle 275 of spraying.
Concrete structure to the liquid container 271, spray nozzle 272, liquid suction tube 273 and the shutter 274 that constitute liquid spraying portion 27 does not limit especially, all can suitably use the known structure in the ejection liquid spraying field.In addition, liquid spraying portion 27 also can possess other member or mechanism.
[action of liquid spraying portion]
Describe if the liquid spraying portion 27 that uses said structure is sprayed the action of liquid spraying, then basic action is identical with the action of spray air-flow.That is, shown in figure 25, when the user made the changer lever 143a operation of side shifting to the back-end, air imported and covers member 143c forward end side shifting, and suction air introducing port 145b is opened.And, at the interflow position of primary flow path 101, to spray an interflow mouthful 142b through moving of stream switching part 146 and be opened with secondary flow road 102, secondary flow road 102 is connected with front end opening 141a, and primary flow path 101 is broken off with front end opening 141a.
Therefore, near the suction force that the 141b of open rearward end portion, produces acts on the inside of the suction chamber 145 that is connected with atmosphere through the suction air introducing port 145b that is opened via internal suction mouth 145a.Thus, shown in the thick-line arrow among Figure 26, form suction airstream towards suction chamber 145, internal suction mouth 145a.Then, be arranged on suction chamber 145 inner power fan 144b and be rotated, spray fan 144a with it linkedly and also be rotated.Therefore, shown in the thick-line arrow of Figure 26, be to form jet-stream wind in the secondary flow road 102 spraying stream portion 142, this jet-stream wind flows to the inside of front end opening 141a.
This jet-stream wind is imported into the inside of spray nozzle 272, and the shutter of therefore holding up for sealing spray nozzle 272 274 is because the distolateral forward lodging of jet-stream wind is ejected jet-stream wind from nozzle 275 thus.At this, between shutter 274 and nozzle 275, be connected with liquid suction tube 273, therefore liquid container 271 inner liquid are directed to spray nozzle 272 inside via liquid suction tube 273 through the ejection of jet-stream wind.Then, shown in the thick-line arrow among Figure 26, this liquid ejects by the jet-stream wind atomizing and from nozzle 275.
Afterwards, if the user removes the state that changer lever 143a moves to rear end side, then stream switching part 146 is opened main body interflow mouthful 141d, and suction air introducing port 145b is imported by air and covers member 143c sealing in addition.Then, make power fan 144b and spray the suction airstream disappearance that fan 144a is rotated, the jet-stream wind that sprays from nozzle 275 also stops.
At this, spray nozzle 272 is connected with primary flow path 101 through main body interflow mouthful opening of 141d, therefore forms suction airstream in the inside of spray nozzle 272.Therefore, the shutter 274 that is in the lodging state is erect through suction airstream, consequently seals spray nozzle 272.Thereby it is inner to avoid liquid container 271 inner liquid all of a sudden to flow into air suction injection apparatus 10D.In addition, even,, therefore can not have any impact to electric dust collector 20 owing to structurally aspirate with vaporific just in case liquid is aspirated by mistake yet.
Like this, in this embodiment, be installed on front end opening 141a, can utilize the spraying of jet-stream wind ejection liquid through portion 27 that liquid is sprayed.Therefore, if use cleaning fluid,, can also remove the dust that to remove through common vacuum cleaning function or above-mentioned blowing function (for example, attached to the dust on the cleaning face etc.) then through spraying vaporific cleaning fluid as liquid.In addition, can also use deodorant or aromatic as liquid, it is indoor that they are spread to.In this case, compare, deodorant, aromatic etc. are scattered on a large scale with the pot type sprayer product that sell in market.Consequently can increase the cleaning kind.
(embodiment 6)
The structure of the air suction injection apparatus that embodiment of the present invention 6 is related is identical with the related air suction injection apparatus 10A to 10D of above-mentioned embodiment 1 to 5 basically; But the related air suction injection apparatus of embodiment 6 do not possess valve member, but the front end opening of main part constitutes rotatable as stream switching part performance function.With reference to Figure 27 to Figure 29 the related air suction injection apparatus of this embodiment is explained particularly.
[structure of air suction injection apparatus]
At first; Like Figure 27 and shown in Figure 28; Air suction injection apparatus 10E that this embodiment is related and above-mentioned embodiment 1 related air aspirate injection apparatus 10A likewise, possess main part 151, spray stream portion 152, fan portion 154 and suction chamber 155.
The structure of main part 151 is identical with main part 111 in the above-mentioned embodiment 1, and its inside becomes primary flow path 101, but in its front front end opening 111a is not set, is provided with rotation peristome 156 with replacing.For main part 151, rotation peristome 156 is front end openings, simultaneously also as stream switching part performance function.Rotation peristome 156b is set to the member that separates with main part 151 (with spraying stream 152); With respect to main part 151 (with spraying stream portion 152); Can be that the center is rotated along its circumferencial direction with shaft 156d, through hole 156a and the blind hole 156b adjacent with this through hole 156a arranged in these rotation peristome 156 set inside.
Through hole 156a is connected with pump orifice 156c and constitutes the stream of circulation airflow.On the other hand, the end that blind hole 156b is connected with main part 151 is the rear end side opening, and the other end is the front sealing.In addition, main part 151 with spray in the stream portion 152, be respectively arranged with main body in the end that connects with rotation peristome 156 and link mouthful 151d and link a mouthful 152b with spraying.Thereby, injection stream portion 152 is set so that adjacent with secondary flow road 102 to main part 151 in the end primary flow path 101 that is connected with rotation peristome 156.
Like Figure 27 and shown in Figure 28, in this embodiment, the nozzle-like of rotation peristome 156 for narrowing down along with trend front end sectional area, only through hole 156a penetrates into the rear end from front end, and blind hole 156b is the rear end side opening only.Certainly being not limited thereto, also can be the structure that suction nozzle 26 annexes such as grade can be installed.In addition, the 151b of open rearward end portion is identical with the 111b of open rearward end portion in the above-mentioned embodiment 1.
In addition, possess the suction chamber 155 of internal suction mouth 155a, fan portion 154 is arranged in the set inside of spraying stream portion 152 and suction chamber 155 in main part 151 set inside.At this; The structure of spraying stream portion 152 also basically with above-mentioned embodiment 1 in injection stream portion 112 identical; But injection air introducing port 152a is arranged on the upper side of spraying stream portion 152 unlike the injection air introducing port 112a that kind of above-mentioned embodiment 1, but is arranged on the upper surface that sprays stream portion 152 with the mode towards the upper surface of fan portion 154.In addition, in suction chamber 155, be provided with the internal suction lid member 155c that comes closed interior pump orifice 155a with the mode that can open and close.In addition, the fan portion 114 in fan portion 154 and the above-mentioned embodiment 1 likewise comprises and sprays fan 154a, power fan 154b and fan shaft 154c.
[action of air suction injection apparatus]
Then, the action of air suction injection apparatus 10E with said structure is explained particularly.At first, shown in figure 27 when common vacuum cleaning function is described, in air suction injection apparatus 10E, the through hole 156a agent-oriention of rotation peristome 156 links a mouthful 151d, and blind hole 156b links a mouthful 152b towards injection.That is to say that primary flow path 101 is connected with rotation peristome 156, secondary flow road 102 is broken off with rotation peristome 156.Therefore, shown in thick-line arrow among the figure, from the pump orifice 156c suction atmosphere of rotation peristome 156, in primary flow path 101, form suction airstream towards the 151b of open rearward end portion owing to the suction force of electric dust collector 20 (not shown in Figure 27 and Figure 28).
Then, switching to blowing function is described.Shown in figure 28, when the user was rotated rotation peristome 156, through hole 156a linked a mouthful 152b towards spraying, and blind hole 156b agent-oriention links a mouthful 151d.That is to say that secondary flow road 102 is connected with rotation peristome 156, primary flow path 101 is broken off with rotation peristome 156.Therefore, shown in thick-line arrow among the figure, near the suction force that the 151b of open rearward end portion, produces pump orifice 155a is internally aspirated suction chamber 155 inner air.
At this, the internal suction mouth 155a that suction chamber 155 is had is by internal suction lid member 155c sealing, but through above-mentioned suction force (suction airstream), this internal suction lid member 155c is opened by suction.Consequently, suction chamber 155 inside are aspirated and power fan 154b is rotated, spray fan 154a thus and also be rotated linkedly via internal suction mouth 155a.Therefore, shown in the thick-line arrow of Figure 28, be to form jet-stream wind in the secondary flow road 102 spraying stream portion 152, this jet-stream wind flows through the through hole 156a of rotation peristome 156, and 156c ejects from pump orifice.
Afterwards; If the user restores rotation peristome 156, then secondary flow road 102 is closed hole 156b disconnection, and primary flow path 101 is connected with through hole 156a; Therefore power fan 154b stops the rotation with injection fan 154a, and the jet-stream wind that ejects from rotation peristome 156 also stops.In addition, in primary flow path 101, form suction airstream, therefore produce suction force once more at through hole 156a and pump orifice 156c place.
At this moment, shown in figure 28, be the position that acute angle ground tilts with tube axial direction and concern the stream portion 152 of spraying that is provided with respect to main part 151, therefore tilt similarly with the lower surface that sprays the suction chamber 155 that stream portion 152 forms as one.Therefore, flowing of suction airstream can be closed the internal suction lid member 155c that is arranged on suction chamber 155 lower surfaces.
Like this; In this embodiment; The stream that rotation peristome 156 constitutes in blind hole 156b and primary flow path 101 and the secondary flow road 102 is connected; Through hole 156a is connected with another stream, therefore rotates peristome 156 except the function as front end opening, also possesses the function as the stream switching part.Therefore, do not use the bar member just can switch to the connection or the disconnection on secondary flow road 102.Therefore, can easily switch blowing function and vacuum cleaning function with simple structure.
In addition,, be connected with rotation peristome 156, can open internal suction automatically and cover member 155c through making secondary flow road 102 when primary flow path 101 is connected with rotation peristome 156 and when not forming jet-stream wind, can closes internal suction lid member 155c in advance.Therefore, injection fan 154a is rotated efficiently, in addition can hinder this power fan of protection rotatably 154b of power fan 154b.
In addition; In this embodiment, also can not possess internal suction lid member 155c; For example shown in Figure 29; Also can be following structure: the fan shaft 154d as the rotating shaft of spraying fan 154a and power fan 154b passes internal suction mouth 155a, extends to the inside of main part 151 from injection stream portion 152.In this structure, spraying between stream portion 152 and the suction chamber 155 151h of bearing portion, the 152c (circle that surrounds with chain-dotted line is in the drawings represented) that is respectively arranged with rotatably mounted fan shaft 154d with the inner surface of main part 151.If this structure is then utilized the 151h of bearing portion, 152c, not only in the interior support fan portion 154 of spraying stream portion 152 and suction chamber 155, also in the interior support fan portion 154 of main part 151, therefore supports fans portion 154 more stably.
(embodiment 7)
The structure of the air suction injection apparatus that embodiment of the present invention 7 is related is identical with the related air suction injection apparatus 10A to 10E of above-mentioned embodiment 1 to 6 basically; But this air suction injection apparatus constitutes the stream switching part that does not possess valve member, itself is made as the injection switching part that rotatable structure realizes and possess through spraying stream portion.With reference to Figure 30 to Figure 37 the related air suction injection apparatus of this embodiment is explained particularly.
[structure of air suction injection apparatus]
At first, shown in figure 30, air suction injection apparatus 10F that this embodiment is related and above-mentioned embodiment 1 related air aspirate injection apparatus 10A likewise, possess main part 161, spray stream portion 162, fan portion 164 and suction chamber 165.In addition, Figure 30 is the cutaway view of the above-below direction (vertically) of air suction injection apparatus 10F.
The structure of main part 161 is identical with main part 111 in the above-mentioned embodiment 1, and its inside becomes primary flow path 101, but its leading section constitutes front end spray nozzle part 161a as the main part 121 in the above-mentioned embodiment 2.Front end at this front end spray nozzle part 161a is provided with pump orifice 161g.In addition, the 161b of open rearward end portion is identical with the 111b of open rearward end portion in the above-mentioned embodiment 1.
In addition, different with the main part 111 ~ 141 in the above-mentioned embodiment 1 ~ 5, spray stream portion 162 and be integrally formed with suction chamber 165 and constitute fan portion resettlement section 167.This fan portion resettlement section 167 constitutes in inside and accommodates the cylindric of fan portion 164, and top is to spray stream portion 162, and the bottom is a suction chamber 165.This fan portion resettlement section 167 along with the direction of the tubular axis of main part 161 (among Figure 30 vertically) quadrature (among Figure 30 laterally), rotatably insert this main part 161.In addition, the direction of insertion of fan portion resettlement section 167 is not limited to orthogonal direction, so long as the direction of intersecting at least gets final product.
Fan portion resettlement section 167 is inserted into main part 161, so its periphery is basically towards primary flow path 101.In addition, the set inside at main part 161 has resettlement section support 161h, the rotatably mounted fan portion resettlement section 167 of inserting of support 161h, this resettlement section.In addition, below fan portion resettlement section 167, be provided with along the tabular passage opening/closing portion 166 of the radial arrangement of this fan portion resettlement section 167.The concrete structure of resettlement section support 161h and passage opening/closing portion 166 is described in addition, in the back.
Fan portion 114 in fan portion 164 and the above-mentioned embodiment 1 likewise; Comprise and spray fan 164a, power fan 164b and fan shaft 164c, as stated, fan portion 164 is housed in the inside of fan portion resettlement section 167; As Figure 31 also illustrates; Spray fan 164a and be positioned at the inside of spraying stream portion 162, as Figure 32 also illustrated, power fan 164b was positioned at the inside of suction chamber 165.At this, Figure 31 is a partial sectional view of representing the inside of the injection stream portion 162 the fan portion resettlement section 167 from the top, looks cutaway view corresponding to the II-II alignment among Figure 30.In addition, Figure 32 is a partial sectional view of representing the inside of suction chamber 165 from the top, is that the III-III alignment among Figure 30 is looked cutaway view.That is, Figure 31 and Figure 32 are the cutaway views with the direction (laterally) of above-below direction quadrature.
Shown in figure 31, the periphery of the injection stream portion 162 in fan portion resettlement section 167 is provided with an injection binding mouthful 162b through excising a part.This sprays and links mouthful 162b for spraying the jet in the stream portion 162.In addition, at the upper surface that sprays stream portion 162 upper surface of fan portion resettlement section 167 (promptly), with injection air introducing port 152a in the above-mentioned embodiment 6 likewise, be provided with injection air introducing port 162a in position towards the upper surface of fan portion 164.Therefore, injection air introducing port 162a and injection link between mouthful 162b becomes secondary flow road 102.In addition, the lower surface of suction chamber 165 is towards primary flow path 101, with internal suction mouth 115a in the above-mentioned embodiment 1 likewise, be provided with internal suction mouth 165a in this position.
In addition, shown in figure 32, above-mentioned resettlement section support 161h is arranged in the outside of the suction chamber 165 of fan portion resettlement section 167.This resettlement section support 161h constitutes crooked wall shape along the periphery of suction chamber 165, and its part is exposed to the outside of main part 161.And, be provided with suction air at this position of exposing and import collar extension 165c.On the other hand, similarly, the part of its periphery is provided with suction air and imports internal orifice 165b in the suction chamber 165 of the state that is in the inside that is embedded into resettlement section support 161h.Therefore; If to import collar extension 165c consistent through fan portion resettlement section 167 being rotated make the suction air that is arranged at suction chamber 165 to import internal orifice 165b and the suction air that is arranged at resettlement section support 161h, then become with above-mentioned embodiment 1 in identical " the suction air introducing port " of suction air introducing port 115b.
Like Figure 32 and shown in Figure 33, passage opening/closing portion 166 major parts that are arranged on the below of fan portion resettlement section 167 are positioned at the inboard of resettlement section support 161h, and a part is positioned at the outside of resettlement section support 161h.The two ends of passage opening/closing portion 166 (inboard of end support 161h in the resettlement section and the outside of other end support 161h in the resettlement section) are for being in the such position relation in same plane, but the position bending between the two ends is to cover the half cycle of internal suction mouth 165a.
Figure 31 is to state shown in Figure 33; Promptly; When vacuum cleaning, passage opening/closing portion 166 disposes along the bearing of trend (path direction) of primary flow path 101, but of the back; Through fan portion resettlement section 167 is rotated, passage opening/closing portion 166 moves to the direction (crisscross) of intersecting with primary flow path 101 and closes this primary flow path 101.In addition, with Figure 31 and Figure 32 likewise, Figure 33 is the cutaway view of transverse direction, but is not to observe from the top and the partial sectional view that obtains, but the partial sectional view that obtains from beneath.
In addition, in this embodiment, fan portion resettlement section 167 is not as long as at least a portion of its periphery towards primary flow path 101, therefore, needs fan portion resettlement section 167 all to be positioned at the inside of main part 161.In this embodiment, shown in figure 31, about 3/4ths of periphery is inserted into main part 161, and about 1/4th are exposed to the outside of main part 161.
[action of air suction injection apparatus]
Then, the action of air suction injection apparatus 10F with said structure is explained particularly.At first; When common vacuum function is described; Shown in figure 31, in air suction injection apparatus 10F, be arranged at the injection of spraying stream portion 162 (fan portion resettlement sections 167) and link mouthful 162b not towards the pump orifice 161g of front end spray nozzle part 161a; And, be in the state that is closed towards inner side near the rear end.That is to say, as the secondary flow road 102 and the front end spray nozzle part 161a disconnection of the inside of spraying stream portion 162.
At this moment, shown in figure 32, the suction air importing internal orifice 165b that is arranged at suction chamber 165 is not overlapping with the open area that the suction air that is arranged at resettlement section support 161h imports collar extension 165c.In Figure 32; Suction air imports internal orifice 165b towards pump orifice 161g, therefore is in the state that is covered by resettlement section support 161h, in addition; The outer peripheral face that imports collar extension 165c place suction chamber 165 at suction air exposes, so this suction air importing collar extension 165c is in the state that is closed.Under this state, can not import air in the inside to suction chamber 165 from the outside.
Therefore; Shown in the thick-line arrow among Figure 31 to Figure 33; Through the suction force of electric dust collector 20 (not shown in Figure 31 to Figure 33), the pump orifice 161g suction atmosphere from front end spray nozzle part 161a forms the suction airstream towards the 161b of open rearward end portion in primary flow path 101.Therewith relatively, in the secondary flow road 102 that is disconnected, do not form air-flow.
Then, switching to blowing function is described.Figure 34 to Figure 37 is respectively and the corresponding cutaway view of Figure 30 to Figure 33, but the state of Figure 30 to Figure 33 when showing vacuum cleaning, and therewith relatively, the state when Figure 34 to Figure 37 shows blowing.
Like Figure 34 and shown in Figure 35, when the user was rotated fan portion resettlement section 167, the injection of spraying stream portion 162 linked the pump orifice 161g of mouthful 162b towards front end spray nozzle part 161a.Meanwhile; Shown in figure 36; The suction air that is arranged at suction chamber 165 imports internal orifice 165b and imports the open area overlaid of collar extension 165c with the suction air that is arranged at resettlement section support 161h, so shown in the thick-line arrow among Figure 36, can atmosphere be imported the inside of suction chamber 165.Thus, can form the suction airstream that imports collar extension 165c, suction air importing internal orifice 165b, suction chamber 165 and internal suction mouth 165a (not shown in Figure 35 and Figure 36) towards suction air.
And, like Figure 36 and shown in Figure 37,, change into crisscrossly along the tabular passage opening/closing portion 166 of path direction configuration through the rotation of fan portion resettlement section 167, close primary flow path 101.Thus, suction airstream can not arrive front end spray nozzle part 161a, only in the inside of suction chamber 165 power fan 164b is rotated.Therefore, spray fan 164a linkedly with the rotation of power fan 164b and also be rotated, shown in the thick-line arrow of Figure 35, in secondary flow road 102, form jet-stream wind, this jet-stream wind front end spray nozzle part 161a that flows through, 161g ejects from pump orifice.
Afterwards; If the user is rotated fan portion resettlement section 167 and is back to original position; Then the sealing of 166 pairs of primary flow path 101 of passage opening/closing portion is disengaged, and primary flow path 101 is opened, and the consistent state of suction air importing internal orifice 165b and suction air importing collar extension 165c is disengaged; " thereby suction air introducing port " is closed; Spray to link a mouthful 162b simultaneously and also be closed, thus power fan 164b with spray fan 164a and stop the rotation, the jet-stream wind that sprays from front end spray nozzle part 161a also stops.In addition, in primary flow path 101, form suction airstream, therefore produce sufficient suction force once more at pump orifice 161g place.
Like this, in this embodiment, close or open through fan portion resettlement section 167 is rotated " suction air introducing port ", and primary flow path 101 also is opened or closes, so function is brought into play as spraying switching part in this fan portion resettlement section 167.Therefore, only through the rotation of fan portion resettlement section 167, just can easily switch the blowing function and the vacuum cleaning function of electric dust collector.
