The best mode that carries out an invention
At first referring to figs. 1 to 4, vacuum cleaner is portable cylinder type, and it has shell 1, and has wheel 2 that is positioned at its place, bottom surface and the suction inlet 3 that is in an end.Dust catcher comprises traditional pump and dust bag or other container (not shown).Side at shell 1 is provided with the hoses limit support member, and its form is the carriage 4 that has U-shaped flange 5, and its purpose will be clear hereinafter.
Dust catcher also comprises flexible pipe 10.Flexible pipe 10 is flexible wave structures, and it comprises flexible spiral reinforcement, and its form is an elastic metallic yarn 11, and it can be at the very high plastic sleeve 12 of the flexibility of inner support outside.Strengthening with conveyor screw can be flexible plastics.Strengthen forming its state that makes, but can overcome its elasticity and axially compressed applying under the situation of external force it with nature expansion with wire 11.Sleeve 12 has enough flexibilities, makes flexible pipe itself present the length of run of strengthening with wire conveyor screw 11 naturally, shown in the dotted line among Fig. 1 and 2.As shown in Figure 4, the sleeve 12 that is in the flexible pipe under its deployed condition has the shallow recessed portion that extends internally between each circle of reinforcement.This just allows sleeve inwardly to fold up between each circle of reinforcement, and therefore flexible pipe can freely be withdrawn when exerting pressure.Perhaps, as shown in figure 10, sleeve 12 ' has outward extending short projection between each circle of reinforcement 11 '.This just allows sleeve 12 ' folded-out when flexible pipe is withdrawn.The advantage of this set is that the aperture of flexible pipe can not reduce during withdrawing, therefore can keep swabbing pressure on the length of flexible pipe.
The rigidity that can regulate hose construction is to obtain required retraction speed.
Flexible pipe 10 has traditional joint 13 at the one end, and flexible pipe can be connected on the suction inlet 3 of dust catcher by this joint, and this joint can comprise and being rotatably connected.Flexible pipe 10 has second joint 14 at its other end, and flexible pipe can be connected on the cleaning head 15 by this second joint.
In joint 14, comprise and can be used for device that the air that passes flexible pipe 10 is blocked.As shown in Figure 4, the form of this device is a baffle plate 16, and it at one end is pivotally mounted on the position that also can be actuated the longitudinal extension of opening in the joint 14 by spring 18 in 17 places.One end of button 19 is exposed to outside the joint 14, and its other end is positioned on the baffle plate of joint.By pressing the button 19, the free end of baffle plate 16 is with regard to the elasticity that overcomes spring 18 and be pressed.In case be depressed into certain distance, the air of the flexible pipe 10 of flowing through just makes baffle plate 16 be drawn into the upright position, and it leans against on the annular seat 20 in the joint and has blocked passage along flexible pipe herein.Baffle plate 16 remains in this closing position and is removed up to suction, and at this moment spring 18 makes the baffle plate swing and gets back to its home position.The rear end of joint 14 is positioned on the side of holding flange 5, so that the free end of flexible pipe 10 is remained on the side of Body case of cleaner 1.Cleaning head 15 can leave in the cavity volume in the shell 1.
In order to use dust catcher, the joint 14 of the free end of flexible pipe 10 is moved to outside the restriction carriage 4.This just allows flexible pipe 10 to present its natural deployed condition, and this is generally about 2 meters length.Be installed in cleaning head 15 on the joint 14 then and connect dust catcher, thereby flexible pipe 10 and cleaning head are applied swabbing action.This is to use in a conventional manner, so that dust etc. is drawn in the dust catcher so that with post processing.
After the user used up dust catcher, before turning off power supply, he can be by the button 19 of the free end of bottom hose 10, so that shut off valve 16 and prevent that air from flowing in the flexible pipe.Pressure in the flexible pipe 10 between valve 16 and the dust catcher descends this moment apace.This has just applied axial pressure to flexible pipe 10, and this is enough to make it to overcome the elasticity of reinforcement metal silk 11 and returns.Flexible pipe 10 is configured to make it to be retractable into than the little a lot of length of its natural length, half of its natural length normally, promptly about 1 meter long.The structure choice of flexible pipe becomes to make that the insufficient pressure after the decline in the flexible pipe is so that hose length produces any tangible contraction during normal clean operation.The user takes off cleaning head 15 and joint 14 is installed in the limited part 4.In case joint 14 is installed in the limited part 4, just can cut off the power that offers dust catcher.In case cut-out power, the pressure in the flexible pipe 10 just will begin to rise, this is not airtight because of vacuum cleaner, and its permission air enters in the flexible pipe and to flexible pipe and pressurizes.Therefore, the compression stress of the generation withdrawal on the flexible pipe will descend, and flexible pipe trends towards returning to its natural length of run.Yet because the free end of flexible pipe 10 is limited part 4 and limits, so flexible pipe can not trail, unless discharge from limited part.The hoses limit part can comprise the housing with definite shape, and main a part of length of withdrawal flexible pipe is arranged in this housing.Flexible pipe 10 is clamped in the curved passage in the housing of shell hinged lid below, so it is fully sealed.
The invention enables and can deposit vacuum cleaner hose compactly, the user need not apply power and come unwinding hoses.Therefore, this makes flexible pipe to use with the lighter dust catcher of weight, and this dust catcher can be pulled or drag forward by spurring traditional stretching flexible pipe.
Flexible pipe needn't have the length of run of nature.The present invention also can be used for the situation that flexible pipe has the withdrawal length of nature.It is lower than tradition stretching flexible pipe to trend towards making the elasticity of the flexible pipe of its contraction can be made into, and this is because the pressure of the decline that is produced when hose free end is plugged helps the withdrawal of flexible pipe.Like this owing to must be applied thereto so that the power of its expansion is littler, therefore just can alleviate or avoid with portable vacuum cleaner on the relevant problem of tradition stretching flexible pipe.Flexible pipe can have the nature withdrawal and launch the combination of type naturally, perhaps as an alternative, can have one section promptly not collapsible also not deployable part.
Be appreciated that the present invention is not limited to the cylinder dust catcher, but for example also can be used in the upright vacuum.
Above-mentioned hose construction becomes to make the increase of swabbing pressure to cause hose length launching and existing between the retracted mode fully corresponding directly related minimizing fully.Perhaps, this length did not all have obvious variation till flexible pipe can be configured such that certain swabbing pressure, in case surpass a threshold value, flexible pipe just changes to the length that it is withdrawn fully suddenly.This flexible pipe can be by making ripple struction asymmetric the realization.
Be used to prevent that air can have many different structures along the valve that flexible pipe flows.This valve can be provided by the plug of various ways, and for example as shown in Figure 5, wherein the elastomeric tether 22 by softness has connected spheroid 20 on joint 21, so the user can upwards lift to the joint end with ball simply and locates to block mobile.Valve needn't fully be blocked air and flow, but is configured to allow air to have flowing of reduction.This is useful for the speed of slowing down the flexible pipe withdrawal.Valve can be conditioned to allow air to flow with different speed.Except using valve, also can only on the joint end, block flexible pipe by the user with hand.Valve can be provided in that it is automatically closed when taking off cleaning head.Valve can adopt the mode of electric control operation, thereby for example by being located at switch on the Body case of cleaner with regard to this valve of remote-controlled operation.This can be arranged so that the Close button on the dust catcher can be before cutting off suction shut off valve automatically.
Flexible pipe needn't be limited by the shell of vacuum cleaner when its retracted mode.As an alternative, the restraint device of some forms of separating with vacuum cleaner main body can be set, for example shown in Fig. 6 to 9.
Fig. 6 has shown the retractible flexible pipe 30 of the above-mentioned type, and it has joint 31 at an end that links to each other with vacuum cleaner shell 32, has at the other end to be used for the joint 33 that links to each other with the burnisher (not shown).Joint 31 links to each other with 35 with cylindrical sleeve 34 respectively with 33.Each sleeve 34 links to each other with 33 with each joint 31 with an end of 35, and the other end of sleeve is that free end 36 and 37 extends in the face of ground mutually.Each sleeve 34 and 35 free end 36 and 37 are provided with the engagement device 38 and 39 of some forms, and they can be bonded with each other and gripper sleeve together. Engagement device 38 and 39 can be many different types, for example has joint flange and engaging groove, the snap close that engages with surface texture, crew-served taper accessory, joint screw or bayonet type assembly parts, magnetic part, joint hook-loop fabric etc.Sleeve 34 and 35 preferably can be crooked, so they can not hinder the deflection of flexible pipe.Because sleeve 34 and 35 can reduce the deflection of flexible pipes 30 at joint 31 and 33 places, so they have and can reduce the advantage that flexible pipe breaks in the position that is easy to generate most damage.Sleeve 34 and 35 length are chosen to make their pattern length equal the to withdraw length of flexible pipe.When the end of flexible pipe 30 was plugged so that its when withdrawal, sleeve 34 and two free ends 36 and 37 of 35 converge, so the user can be bonded with each other them.Just can close vacuum cleaner then, this is because the sleeve 34 and 35 that engages can be fixed on flexible pipe 30 its withdrawal length.Withdrawal flexible pipe 30 can leave on the vacuum cleaner main body, perhaps pulls down and for example deposits individually by linking up with 40 from joint 31.
Except smooth sleeve as shown in Figure 6, sleeve 34 ' and 35 ' can be a corrugated as shown in Figure 7, and it has the withdrawal length of nature so that they have only covered the more flexible pipe 30 ' of small part when using dust catcher.For with sleeve 34 ' and 35 ' securely together, the user only needs their free end 36 ' and 37 ' is moved to together sleeve being stretched to its length completely, so engagement device 38 ' and 39 ' can be fastened to together.
Will not be arranged on opposite place, two ends by two sleeves, this is because long sleeve 42 just can be used for realizing identical functions, as shown in Figure 8.
Sleeve or a plurality of sleeve need not to be solid, and it for example can replace by being located at flexible pipe strip material or one group of belt on every side.
The retainer device that exists multiple alternative form can be used for flexible pipe is remained on its withdrawal length.The form of retainer device can be enclosed in the sack around the withdrawal flexible pipe.This sack also can have the device that is used for deposit clean out rod and annex after flexible pipe removes.
Retainer needn't be permanently secured to flexible pipe from one's body, but only when flexible pipe is withdrawn, be connected independent parts on the flexible pipe.
Fig. 9 has shown an independent retainer that form is an outer rigid housing, and it has along its side two housings 50 and 51 that link to each other by flexible hinge 52, and has semi-cylindrical cavity 53 on each surface.The half- cylindrical rib 54 and 55 at place, the two ends of each housing be configured as can with arbitrary connector engages at place, flexible pipe two ends, perhaps engage with arbitrary end of flexible hose self.Two housings 50 and 51 be folded in the withdrawal flexible pipe around, and tighten together by engaging snap close 56.Shell is preferably in place, its two ends and has flange 57, and it is configured as has rigidity clean out rod and other annex and can be clipped in wherein groove 58, so flexible pipe and annex just can store together.
Retainer can extend in flexible pipe, and for example provides by the vacuum cleaner rod of rigidity and suitable joint.
