Detailed description of the invention
In Fig. 1 and 2, diagram is for the cross-sectional side view of the suction nozzle 1 of vacuum cleaner (not shown).Suction nozzle 1 comprises main body or shell 2, and this main body or shell have elbow or suction pipe connector 3, and this elbow or suction pipe connector are attached to the rear end of shell 2 for rotating with respect to shell 2 around axle A.The suction pipe 4 that does not form the part of suction nozzle 1 can be attached to suction pipe connector 3 and upwards extend from suction pipe connector 3.Suction pipe 4 is provided for the pipeline that dust and residue pass through, and this dust and residue are sucked from the surface by suction nozzle 1 vacuum cleaning ' S '.Suction pipe 4 also serves as for allowing user can be during use promote suction nozzle in (' F ') direction forward and pull its handle in (' R ') direction backward.
In the first embodiment, wheel 5 is installed to shell 2.It is also installed to suction pipe connector 3 and guides suction nozzle 1 for the axle around identical with suction pipe connector 3 ' A ' rotation to support suction nozzle 1 and to cross over surface ' S '.
The downside of shell 2 has the base plate 6 contacting with the surface ' S ' of vacuum cleaning.Elongated suction channel groove 7 be formed in base plate 6 and with ' F ' forward and backward ' R ' moving direction width of crossing over shell 2 that substantially meets at right angles extend.Elongated suction channel groove 7 has parallel forward position and rear along 7a, 7b, and these are along the edge that limits the groove 7 in base plate 6.Also can there is difformity by understanding groove 7.
7a provides thread (thread) or residue pick-up bar 8 to discharge hair or thread to assist from the surperficial S of vacuum cleaning along 7b forward and/or rear backward ahead of the curve.
Pick up level in order to realize high dust, be necessary to maintain that suction channel groove 7 contacts with surperficial S, forward position should keep contacting with surperficial S along 7a, 7b with rear.Therefore, the position of bothrium 7, wheel shaft A and the direction that applies power to shell 2 via suction pipe 4 and suction pipe connector 3 are all key factors, because they are determined the behavior of suction nozzle 1 and act on the power of suction nozzle 1.
Opening of matte (pile) from surperficial S, such as carpet picks up dust main phenomenon behind.In order to open matte during the upper mobile suction nozzle 1 of forward direction ' F ', must apply vertical power to the forward position 7a of bothrium 7.But except the power generating due to suction nozzle 1 weight own, the horizontal frictional force of crossing over carpet S for promoting suction nozzle 1 only applying via suction pipe 4 for user effectively generating in this direction.In order this frictional force to be transformed into the vertical power of forward position 7a to open matte, distance h (seeing Fig. 2) is important.Distance h is that the rotating shaft A of trailing wheel is to the distance of surperficial S and equal to take turns 5 radius.Along with distance h increases, downward vertical power V that offset with matte, suction edge will be higher in the time that user promotes vacuum cleaner surfacewise on forward direction F, and this user applies power via suction pipe 4 to suction nozzle in the direction of extending along line P.
But in the stroke backward ' R ' of suction nozzle 1, be important apart from q (seeing Fig. 2).Extend and the length of the line that intersects at a right angle with line P from the forward position 7a of bothrium 7 apart from q representative, apply along this line P to suction nozzle 1 by user and pull suction pipe 4 to cross over woollen blanket S and the power that generates.
In the time that user pulls back suction nozzle 1, there is apart from the trend of q approaching zero, generate moment/torque (as shown in the arrow T in Fig. 2), this moment/torque makes forward position 7a on carpet S the pivotable of suction nozzle around bothrium 7, this causes suction nozzle 1 to tilt and takes turns 5 and mention (as shown in the dotted line that is designated as 5a Fig. 2) until torque T is zero from ground, when this comes across forward position 7a and all drops on the line identical with the power P applying with wheel shaft A.Pick up level in order to reach high dust, this tilting action is less desirable, because the rear of bothrium 7 no longer contacts with carpet S along 7a, therefore air will start to infiltrate by bypass path instead of by carpet, and therefore this is less desirable and causes suction performance to reduce.Tilting action also causes the spring beastly of suction nozzle 1, irregular movement.
Ideally, should remain as far as possible little to minimize the above more specifically less desirable tilting action of explanation apart from q.Need chosen distance h to maintain vertical power V, this vertical power will maintain bothrium 7 and offset with matte in the time of the upper promotion of forward direction (F) suction nozzle simultaneously.
Inventor has determined the requirement that prevents the suction loss in the time that forward direction (F) above promotes suction nozzle for balance, and the spring of suction nozzle and the requirement of irregular movement when minimizing or alleviating suction nozzle 1 and pull in backward directions (R) (by maintain low apart from q and keep aforementioned torque T for minimum), wheel diameter is important with certain combination of distance at the center that takes turns to suction channel.By these parameters of careful selection, have been found that to have realized at effective dust and pick up and user's well balanced between easily mobile its needed power for promote suction nozzle in (F) direction forward time and while also pulling it in backward directions (R).
Ideally, inventor have been found that 24mm the best when providing suction nozzle 1 to pull it in backward directions (R) should be provided size q may performance.
Apart from q and wheel shaft A, the distance more than surperficial S (is above-mentioned size h, this is equivalent to the radius of wheel 5) relevant with size X (seeing Fig. 3), this size be the contact point Y of wheel 5 under axle A and surperficial S and in the front and rear of suction channel groove 7 along the distance across surperficial S between the center line M (seeing Fig. 3) in the middle of between 7a, 7b, this center line is with the front and rear of suction channel groove 7 along the two parallel and equidistant imagining center line of 7a, 7b.If suction channel groove has width C, center line be positioned apart from front and rear along 7a, the 1/2C place of 7b.Inventor has been found that by increase and takes turns 5 diameter and by more closely locating wheel shaft A to reduce distance X with bothrium 7, and that q will become will be less, reduce torque T thus and make to be easier to pull suction nozzle on the upper leap of direction (R) surface.
Here should be noted that suction channel groove 7 be shaped as ideally rectangle and with suction nozzle meet at right angles with R with moving direction F backward forward and the direction parallel with wheel shaft on cross over suction nozzle width extend.But possible be that suction channel groove can be in some way shaped or extends by angle, in this case, should obtain above-mentioned measurement X from the central point in the middle of between every end on the direction of width of crossing over suction nozzle 1 of groove.
In order to realize q < 24, the relation between wheel radius h and size X should be:
In one embodiment of the invention, suppose that bothrium width is 20mm this formula of deriving.Preferably, well width is in 18 to 21mm scope.
Inventor has realized that acquisition is best in the upper promotion of forward direction (F) or in the time that backward directions (R) pull suction nozzle may pumping efficiency and dynamic response by making distance X < 80mm and wheel radius > 25mm.Although but in these parameters, comprise by understanding the ratio that is less than 0.3 for some well widths, the parameter that is to provide the ratio that is greater than 0.3 represent preferably a kind of, picks up the balance between efficiency and the movement of suction nozzle because it further serves raising at dust.
By further illustrating, if ratio is less than 0.3, less in the needed power of forward direction (F) upper promotion suction nozzle, the vertical power V that acts on the forward position of suction nozzle also will be so.Thereby dust picks up efficiency will be reduced.Also cause q value larger but be less than 0.3 ratio, therefore, pull suction nozzle in backward directions (R) time, make the torque that suction nozzle tilts required increase.In the parameter of selecting to specify so that when the ratio that is greater than 0.3 is provided, apply for user for promoting forward the given force of suction nozzle, the vertical power V in forward position that acts on suction nozzle is higher with respect to selecting any situation of the parameter less than the ratio of specifying.In addition, utilize and be greater than 0.3 ratio, q will still less, and this causes producing than all torques to suction nozzle still less of any situation of selecting setting outside the ratio specifying for identical frictional force.
In one embodiment of the present of invention, therefore a kind of suction nozzle for vacuum cleaner is provided, this vacuum cleaner comprises: there is the shell of base plate, base plate have therein for the suction channel groove from area suction residue; Wheel, is installed to shell for around rotating to support suction nozzle on described surface along the axle of substantially parallel extension with the front and rear of described suction channel groove; And suction pipe connector, be installed to shell for the axle rotation around coaxial with described wheel shaft.The radius (h) of wheel and the distance that is greater than 0.3 across the following ratio of distances constant on surface, this distance is point middle between wheel and contact point (Y) surperficial, under wheel shaft and the front and rear edge of suction channel groove.In the time that preferably dropping in 18 to 21mm scope, the width of bothrium selects parameter to the ratio that is greater than 0.3 is provided.
Embodiment shown in Fig. 4 is pivotally installed to suction pipe connector 3 and shell 2 and is pivotally installed to suction pipe connector 3 for identical with embodiment shown in Fig. 3 the second axle B rotation around separating with wheel shaft A except taking turns 5.Link arm 10 is extended and shell 2 is connected to suction pipe connector 3 between axle A and B.To understand in this embodiment, shell 2 can and be taken turns 5 motions around axle A independently around axle B pivotable with suction pipe connector 3, and therefore shell 2 can adopt different angles during stroke forward and backward.
Fig. 5 is to provide the table that utilizes multiple ratios that different vacuum cleaner suction nozzles obtain from the equation of above mark, and these vacuum cleaner suction nozzles have the different value for distance X, wheel radius h and well width C.Also shown that being greater than 0.3 o'clock dust at the ratio calculating picks up efficiency and the resistance of motion as where optimized.Suction nozzle 1 represents according to suction nozzle of the present invention, and suction nozzle 2,3 and 4 represents the suction nozzle of prior art.Although the value that this table representative obtains from having the suction nozzle 1 of the two hinge arrangement as described with reference to Fig. 4, uses the suction nozzle that only has a pivotal point of describing with reference to Fig. 3 to obtain similar advantage.
