The effect that above-mentioned formation produces is as follows.
When dust suction is carried out on ground, earlier the air entry 10 of connecting tube 11 with main body 7 linked, connection 22 first line of a couplet in front tube 14 connect extension pipe 13, connect upper ground surface suction nozzle 15 at extension pipe 13 front ends, hold the handle 12 on the front tube 14 then, ground dust is sucked from ground suction nozzle 15 by the attraction of motor 4; The dust that sucks passes extension pipe 13, front tube 14, flexible pipe 8, connecting tube 11 and air-breathing 10, is collected by the dust bag 2 in the dust storage chamber 3 that is located at main body 7.
Sofa, corner, curtain, table surface and ground suction nozzle 15 being stretched the slit of not entering etc. when locating to clear away, earlier ground suction nozzle 15, front tube 14 are pulled down from extension pipe 13.At this moment, press button 31 on the buckle 28 with extension pipe 13 when front tube 14 is pulled down, as shown in Fig. 2,6 and 9, the combination that is arranged between first joint portion 34 on the brush support 21 in the suction nozzle on the front end of front tube 14 first combined 35 and the buckle 28 will be disengaged, and first stop component 25 becomes and no longer withstands on the extension pipe 13 coupled mouthful 27.Like this, the brush support 21 that is positioned at front tube 14 tops will rotate to connecting port 22 1 sides under the elastic force effect of hook-type spring 23, first stop component 25 will withstand the antetheca 26 in hole 24, and brush 20 is maintained at respect to front tube 14 at an angle under the state of α.Under such state, suction nozzle 18 just can locate to carry out dust suction to sofa, corner etc. at once.
In addition, by making brush 20 always add strength towards cleaning face one side by hook-type spring 23, not only can make the fitting tightly property with swept surface become excellent, realize high efficiency dedusting, even swept surface changes with respect to the angle of front tube 14, the brush face also can be along with swept surface rotates.Like this, the angle of handle 12 there is no need to change, and service efficiency can be improved, and the dust suction performance also can be improved.
And, for the dust that toothpick and button, handstone etc. have some weight, even being in normal angled (in the present embodiment for α) time at brush 20 also may not suck up it, but by front tube 14 is pressed tightly on swept surface, the angle of brush 20 is changed, will shorten to the distance the connecting port 22 of front tube 14 from the front end of brush 20, the vacuum pressure of brush 20 inside will increase, thereby also this class dust can be sucked up.Therefore, the present invention can provide the suction nozzle 18 of a kind of and actual dust suction state fit, dust suction excellent performance.
In addition, even brush support 21 is added very big power on the direction that moves towards front tube 14,, therefore can prevent that also swept surface is scratched owing to be provided with the buffer unit that forms by soft material around the fore-end of right casing 36, left shell 37.And under brush 20 was received and kept state in right casing 36, the left shell 37, the fore-end of brush 20 will protrude than right casing 36, left shell 37.Can prevent further that so not only swept surface from sustaining damage, and brush 20 also can carry out dust suction simply under its storage configuration, can also prevent that simultaneously brush 20 from fault such as can not stretching because of being stuck on right casing 36, the left shell 37.In addition, be set at 60 ° by the angle [alpha] with brush 20, handle 12 will roughly be in parastate, so by very natural posture handle 12 will be moved, and dust suction is got up very light.
In addition, when brush 20 is deposited into, when perhaps extension pipe 13 being connected with front tube 14, because the elastic force of brush 20 is configured to more than or equal to hook-type spring 23 added elastic force, therefore by brush 20 is pressed on the swept surface, brush support 21 is rotated, first combined will combine with first joint portion on the buckle 28, make brush support 21 be positioned at and be maintained at the top of front tube 14, be stored in right casing 36 easily, in the shell 37 of a left side, coupled 27 on the extension pipe 13 is easily inserted in the connection 22 on the front tube 14 connects.
In addition, even brush 20 is not received and kept the words of getting up, because brush 20 is provided with opening portion as shown in Figure 10, that supply the coupled mouth 27 on the extension pipe 13 to insert, so words by coupled mouthful 27 on the extension pipe 13 is inserted, again extension pipe 13 rotated along the opening portion of brush 20, will head on first stop component 25 and be inserted in coupled 27 on the extension pipe 13 for coupled mouthful 27, brush support 21 can rotate simultaneously, is positioned at the top of front tube 14; And combine with first joint portion 34 of buckle 28 for first combined 35, thereby locate/remain on the top of front tube 14.The major part of brush support 21, lid 41 and brush 20 also can be stored the inside at right casing 36, left shell 37.Like this, be under the storage configuration and dirty easily brush support 21 and brush 20 etc. are difficult for being touched by the user, dirty part in appearance can be not eye-catching yet, and very health seems.
In addition, by being provided with when brush support 21 is in certain angle [alpha] the lid 41 that the slit that will produce between brush support 21 and the front tube 14 is covered, brush support 21 can not become greatly, and front tube 14 between can form connected component 21A.And, amplify even strengthen rotational angle α, the expansion cleaning scope of brush support 21, still can make suction nozzle 18 keep miniaturizations.
Like this, the suction nozzle 18 that uses when sofa and corner etc. is located to carry out dust suction need not to install, dismantling operation, the user can not touch suction nozzle 18 and the brush 20 that is used to suck dust yet in addition, can select the user mode and the storage configuration of suction nozzle 18 linkedly with the mounting or dismounting operation and the cleaning operation of extension pipe 13, performance easy to use is significantly improved, thereby the suction nozzle 18 that can realize a kind of cleaning, the property deposited is good and the cleaning performance is also excellent can obtain extraordinary effect.
In addition, though only the suction nozzle that has brush is illustrated in the present embodiment, but, so long as the formation that can when brush support 21 is deposited, it can be maintained by buckle 28, even be not provided with on 20 ones on the brush for coupled mouthful 27 opening portion that inserts on the extension pipe 13, but adopt the slit of for example the suction inlet front end being drawn in the form of suction nozzle, also can obtain same effect.In addition, even first stop component 25 that is located on the brush support 21 is withstood be lengthened out on the pipe 13 coupled mouthful 27, also can reach the same effect, thereby can adopt simple more structure, this is conspicuous.
In addition, even suction nozzle of the present invention is arranged on the front end of extension pipe, also can reach the same effect, this also is conspicuous.
In addition, scope of the present invention is not subjected to the restriction of present embodiment.
In sum, adopt the words of the suction nozzle among the present invention, on front tube etc., can not touch suction nozzle during the mounting or dismounting suction nozzle, and, in the cleaning operation, also carrying out the mounting or dismounting operation of extension pipe easily, suction nozzle also can be deposited simultaneously, health not only, ease of use also can be improved, and the cleaning performance also is expected to improve, and is a kind of very effective suction nozzle therefore.
