Description

Hair-dryer with changes of section device of air stream outlet

Technical field

The present invention relates to a kind of device that hair is dry and/or be shaped that makes, particularly a kind of have a hair-dryer that hair-dryer blows out the outlet changeable device of air-flow.

Background technology

The hair-dryer of family expenses or specialty generally comprises a shell with a handle, shell have make air in shell the inlet net and outlet between the device that flows and the heater of blow out air.Air flow arrangement is made of a fan driven by motor.The problem that this hair-dryer proposes usually is how to change current rate and the shape that blows out from hair-dryer, to adapt to different hair styles.

In order to address this problem, most of hair-dryer uses the detachable accessory on several blowing ends that are installed in hair-dryer.Each annex constitutes the nozzle that definite shape and function are arranged, therefore, for from a kind of shape transition to another kind of shape, perhaps, must change annex in order to change dry type.This just has the shortcoming that needs to change several accessories in dry run, and this just becomes pretty troublesome, and particularly annex is installed near the heater.Another shortcoming is that the quantity of annex is multiplied, and therefore occupies very big place in for the space of placing the hair-dryer setting, and the limited amount of the shape of air-flow and intensity.

In the hair-dryer of describing in other hair-dryer, particularly document FR1546750 or US4977306 each is used a pair of movable valve, and this is hinged on around some axles that are positioned at the hot-air discharge pipe, so that stop up this pipeline more or less valve.Therefore can dwindle the free cross-section of air duct more or less around the rotation of their hinge axis by valve, but cannot see the channel cross-section of new generation from the outside, therefore be difficult to select the direction of the relative hair locks of hair-dryer.This is very inconvenient when beginning to make hair dry, and becomes pretty troublesome in the operating process that need adjust the valve position according to the degree of degree of drying or Hair styling continuously.Particularly the variations in flow device is included in the structure of hair-dryer, and they do not have the annex as device.

In other document, in FR2640857 or WO00/33697, the change of outlet is observable, but changes the air-flow that the mechanism that this cross section uses makes hair-dryer or sends a cylindrical cross-section, perhaps the air-flow of plane section does not have the centre position between the two.In addition, in first document, promptly among this China invites the person's the FR2640857, outlet nozzle is made by a kind of material of elastically deformable, and the forming machine that is used for this nozzle is quite complicated.For the longitudinal axis vertical rotation of 00/33697, two guiding valve of document WO and hair-dryer and outstanding from the side, so that obtain flat eject position, make hair-dryer send the air-flow that departs to the side, rather than concentrate on the center, so that the localized immobilization hair style; In addition, two side direction guiding valves have increased the size and the volume of nozzle.

The another kind of annex that is used to make the air-flow skew that hair-dryer produces has been described in the document WO 97/09899.This annex is a diffuser that is used for fixing a hair-dryer outlet, diffuser has a hollow body, one of hollow body air-supply end has the eyelet that some ventholes and some other hollow pins are passed, and the free end of hollow pins also has the outlet eyelet of some hair-dryer blow out air.Hair-dryer has a device that can change protruding pin length in addition, makes them leave scalp more or less, and sends the air-flow of dispersing.This annex can not be fixed the focused airflow that hair style is used, and its volume is very big in addition.In addition, the diffuser of a large volume can not make air-flow quicken.If little acceleration takes place, because the quantity of changes of section is big, quickening can rough air, makes air-flow become very disorderly, and this can cause being difficult to regulating the temperature of the air-flow that comes out from diffuser.

Summary of the invention

The objective of the invention is to overcome above-mentioned shortcoming, and a kind of hair-dryer that makes hair-dryer blow out the outlet continually varying device of air-flow that has proposed, this device can use the device of a compactness and designs simplification to make a multidirectional dispersion air-flow carry out the transition to a unidirectional focused airflow gradually, but and reverse transition.

Another object of the present invention is a kind of hair-dryer with device of an outlet shape that can change the air-flow that hair-dryer blows out, can see the cross sectional shape of such change simultaneously.

An additional purpose of the present invention is a kind of hair-dryer that changes the device of air-flow that has, and this hair-dryer is effective, reliable, and can low-cost industrialization manufacturing.

These purposes reach by a kind of hair-dryer, this hair-dryer has a shell, shell has the device that air-flow is flowed between arrival end of described shell and port of export, near and device that is positioned at the port of export and can changes the air stream outlet cross section, described device has at least two starting drives that are arranged in the valve of air-flow and described valve is rotated, and described device has one between two valve and can the axially movable tubular nozzle of relative wind.

Therefore, the device that changes the air stream outlet cross section has at least two rotation valve tubular nozzle both sides, and tubular nozzle preferably is positioned at the center of device, and the longitudinal axis of device is on the extended line of the hair-dryer longitudinal axis, and is parallel with air-flow.Valve can rotate around some rotating shafts, and these rotating shafts can be parallel with air-flow, vertical even be tilted, so as when valve move the outlet of obstruction air-flow.Therefore, this outlet changes between a maximum and a minimum of a value, and the air communication that blows out by hair-dryer when valve is out-of-date to be maximum, air communication to or obstructed to the external world, be minimum of a value when valve stops up this passage.Tubular nozzle is between two valve, and when being stopped up by valve in the outlet of air, air-flow is guided through tubular nozzle and flows out from device.

Nozzle is can be axially movable, reaches more outstanding than shell when it move, and this makes the user can be well towards the zone that makes Hair styling or drying.Nozzle can or use different actuating mechanisms and valve to move simultaneously by same mechanism, perhaps in a modification, can move a time of separating, the actuating mechanism of use can first mobile valve moving nozzle or opposite then.

Therefore, when valve is in maximum open position, whole directions that the air that blows out can give for the outlet of hair-dryer, perhaps air-flow can be drawn towards the external world by the shape of valve.Along with the rotation of valve, valve turns over to nozzle, so that air-flow is guided in the space between valve and the nozzle.Therefore, obtain air-flow during beginning, obtain unidirectional focused airflow during end to a plurality of direction diffusions, and all centre positions between these two extreme positions, a position can be carried out continuously or intermittently to the transition of another position.

Therefore can obtain difform air stream outlet cross section, therefore also can obtain the air-flow that the hair-dryer of varying strength blows out, be used to make the low-intensity air-flow of the dispersion of hair drying to carry out the transition to all other zones that to point to the headband that to fix or hair at an easy rate always so that make the concentrated air blast of Hair styling since one.

Described nozzle preferably can move in translation.

Certainly, it is contemplated that nozzle has the aggregate motion of axial component to move axially according to a screw or another.But, because designs simplification, also pass the sheet air-flow that more having of nozzle points clearly to, so that fixing hair style has been selected moving axially of nozzle in order to obtain one.

In addition, the inventive system comprises the control device that nozzle and valve are moved simultaneously.

This has simplified the comfortableness of using and using of the hair-dryer with a this device greatly, blows out the intensity of air-flow and the position of nozzle because can use a single control device to regulate.

Described control device preferably includes a rotary ring.

The device that changes the air stream outlet cross section is positioned at the air outlet slit end of hair-dryer, for this reason, its profile and the profile of shell is adapted, and is cylindricality therefore.User's hand can rotate an air outlet slit pipe with hair-dryer at an easy rate and have the ring that same shape and diameter are more or less the same, and the motion of ring can be used to drive nozzle and/or valve.So just has existing compact structure, the advantage of the fine controlled motion amplitude of getting back simultaneously.

In addition, the inventive system comprises a rotation ring be converted to first mechanism that moves of nozzle and one nozzle move or the rotation of ring is converted to second mechanism of the rotation of valve, at least one in the described mechanism is subjected to the control of rotating ring.

Therefore, the rotation of ring can act directly in the rotation of valve, and valve acts on again on the moving of nozzle, and perhaps opposite, ring can drive nozzle, and nozzle drives valve again.Such structure can obtain all motions that need of valve and nozzle by the simple motion of rotating ring with the simple and effective method of operation.

Described first mechanism preferably is made of a protruding pin that is connected with the outer surface of nozzle body, moves in the helicla flute of protruding pin on the control loop inner surface.

Therefore, control loop converts nozzle to along the moving of same axle around the rotation of the hair-dryer longitudinal axis, and the longitudinal axis of hair-dryer is exactly the air-flow at device center.It is very simple and reliable on the structure that such structure is proved to be.

In addition, described second mechanism is made of a protruding pin that is connected with an end of valve, moves in the tipper of protruding pin on the nozzle body inner surface.

When advance in the path that a tipper of nozzle body inner surface is determined, be used to make valve to rotate at a protruding pin that is connected with an end of valve the mobile of nozzle body of the core support nozzle of nozzle.This structure very simple and that be convenient to realize is very suitable for driving simultaneously several valve, keeps little volume simultaneously again.

The protruding pin that links to each other with a valve is preferably in the tipper and moves along a direction, and the protruding pin that links to each other with relative valve moves along opposite direction in a tipper radially relative with first groove.

Therefore obtain being positioned at the rotation of two whiles of two valve of nozzle both sides, but direction is opposite, a valve clockwise rotates, another valve rotates in the direction of triangle, this closes valve gradually, and preferably closes to nozzle, and air is guided in the more and more narrow finedraw, join up to valve and nozzle, and close the space that exists between valve and the nozzle fully.

In addition, when valve moves, the free area value of outlet between 2: 1 and 14: 1, be preferably in the scope between 3: 1 and 8: 1 and change.

Find when testing, obtain the outlet when determining the size of valve and nozzle and in above-mentioned scope, change, therefore mode focused airflow to optimize, so that make the dry and fixing hair style of hair, and can the special damage hair.People find that also the area that reduces the outlet in these limits can use continuously, need not to cut off the radiator valve of the superheated starting of heating element heater.

Device of the present invention preferably is fixed on the shell of hair-dryer removably.

Can take off device like this and clean, perhaps can also use the hair-dryer that does not have socket pipe, perhaps other annex is contained on the hair-dryer.

The specific embodiment

As shown in Figure 1, hair-dryer according to the present invention has a shell 1, one is arranged in shell 1 by a fan driven by motor, guarantee air at mobile between the inlet 4 at shell 1 rear portion and the outlet 5, airflow flowing heater and also all be arranged in shell in hair-dryer with the jockey of power supply in end opposite.The starting of hair-dryer and stop to be undertaken by firing switch 9.

Hair-dryer also has a device 3 that can change the shape of air outlet slit section S, and this device is fixed on the end of air outlet slit 5.Device 3 can be permanently affixed on the end 5 of shell 1, and also removably opposite shell 1 is installed, for example by the fixture of a band plug or the assembling etc. of exerting oneself.

As what can see better among Fig. 2, device 3 has a tubular bearing 10 with other part of device, one of its end has some plush coppers 11, these plush coppers 11 are embedded in the passage of correspondingly-shaped of end 5 of shell 1, and handle assembly 3 is fixed on the hair-dryer so that snap in fixedly by one.The end of the end opposite of bearing 10 is circumferential edges 15, as the baffle plate of a circumferential ring 28.Have two otch parallel 16 on the part of bearing 10 outer surfaces, the mobile guiding of the nozzle body 12 that below the both sides of bearing 10 form one, will describe with its longitudinal axis.

Cut two radially relative windows 14 in bearing 10, their edge is used to keep two supports: upper bracket 18a and lower carriage 18b.The shape of each

support

18a and 18b all is a cylindricality fan, and has the through hole 19a of the rotating shaft 22a, the 23a that accept to go up

valve

6a, 8a and accept the through hole 19b of rotating shaft 22b, the 23b of

valve

6b, 8b down.Support is two parts that separate, and on window 14, is in order to simplify manufacturing, to be convenient to the assembling of apparatus parts then by pressure fixing like this.Two support 18a, 18b that merge into the single ring-shaped work pieces that elastomeric material makes can also be set, and by its flexible fastening around bearing 10.

In example shown in the drawings, used four valve, two

last valve

6a, 8a that the central shaft that is positioned at device 3 is above, two are positioned at an opposite side and are symmetrical in following valve 6b, the 8b of the central shaft of device 3 with first group of valve.

As what can notice among the figure, each

valve

6a, 6b, 8a, 8b have the shape of camber blades, and the longitudinal section is a circular arc.

Valve 6a, 8a have two projections on each, and these two projections form turning cylinder 22a, the 23a that is positioned at the valve end respectively, make each be supported on one respectively and rotate in the eyelet 17a of the corresponding eyelet 19a of support 18a and tubular bearing 10 inner

surfaces.To following valve

22a, 22b also is the same, and each in them has two the turning cylinder 22a, the 22b that are supported to rotate by eyelet 19b, 17b.

Except two rotation projections, the side of

valve

6a, 8a has directing pin 20a, a 21a in tipper 24a, a 25a of nozzle body 12 lower surfaces on each.The rotation of directing

20a, 21a mobile control each valve 6a, the 6b in groove 24a, the 25a of correspondence, equally, when among directing

20b, 21b corresponding tilt groove 24b, the 25b in nozzle body 12 inner surfaces when mobile, following

valve

6b, 8b rotate around their axles separately respectively.

Can see that as Fig. 2 device 3 also has one becomes the tubular nozzle 7 of lengthening of a part with nozzle ring body 12.Nozzle 7 is connected with nozzle body 12 by pawl 13, and the setting of pawl 13 is in order to slide in the slit 16 of tubular bearing 10, therefore to guarantee moving of guiding nozzle body 12.

The passage that tilts to a direction or groove 24a, 25a are arranged on this surperficial top and at passage or groove 24b, the 25b of this bottom, surface inclined in opposite directions in two radially relative zones of nozzle body 12 inner surfaces.The longitudinal axis of

groove

24,25 and device forms certain angle.The value at angle of inclination and the length of each groove are all passed through calculating, and is just as will be explained below, and each valve can be rotated between a maximum open position and a maximum closed position fully.

The outer surface of nozzle body 12 has a protruding pin 27, and the setting of this protruding pin is in the helicla flute 30 that is embedded in circumference control loop 28 inner surfaces.

The slip of nozzle body 12 is controlled by a control loop 28 around tubular bodies 10 and nozzle body 12.For this reason, the inner surface of control loop has a helicla flute 30, and the protruding pin 27 of nozzle body 12 is embedded in the helicla flute.An interior hoop 31 of control loop 28 stops control loop to move forward, because it is blocked on the edge 15 of tubular bearing 10.Therefore stop control loop to move axially, but it can rotate around the longitudinal axis of the device 3 on the longitudinal axis extension line that is positioned at hair-dryer.

For example can be by a kind of plastics also by the different component parts of injection technique constituent apparatus 3, the part of motion can be made with plastics or a kind of plastics or other material with good resistance frictional behaviour that adds molybdenum bisuphide of POM type.As modification, can reduce friction by using a kind of lubricating grease or a kind of film lubrication moving parts or their guiding device.

During use, rotate and moving axially of nozzle body 12 with nozzle 7 controlled in the action of groove 30 on protruding pin 27 around its axle by making control loop 28.By edge 15 decisions of tubular bearing 10, the back edge 32 by control loop 28 determines the motion amplitude of nozzle 7 on the other hand on the one hand.The mobile control again of nozzle body 12 is gone up

valve

6a, 8a and is rotated to a direction, with

valve

6b, 8b rotate round about at present.

Fig. 4,5 is illustrated in two devices 3 in the extreme operating position.In the position of Fig. 4, nozzle 7 and is gone up

valve

6a, 8a and following

valve

6b, 8b all towards the circumference of bearing 10 fully in the bearing body 10 of device 3, in the maximum separation position of they and nozzle 7.In this position, the air-flow that hair-dryer blows out is in the direction of arrow of guiding lower edge Fig. 4 of the straight walls of the curved wall of valve and nozzle, and this is a multidirectional dispersion flows.In this case, the area maximum of the free cross-section of air outflow.

In order to reach position shown in Figure 5, rotate control loop 28 to greatest extent, make nozzle 7 be in fully the position of stretching out, and valve turn down, to stop the space that exists between bearing 10 and the nozzle 7 fully from the front end of bearing 10.In this position, the air that hair-dryer blows out can only divide from central division along the direction of Fig. 5 arrow indication by nozzle 7 and blows out.In this case, the air-flow that obtains is an axial focused airflow.The free area that air flows out reaches its lower position here, and this value is near the area of section of nozzle 7.

Therefore, just can control the cross section value of air outflow and the intensity of air-flow to a direction or another direction rotation control loop 28.Therefore, air outflow cross section can be any centre position between two extreme positions shown in Fig. 4,5.

Can consider not exceed other modification of claim scope of the present invention.

For example, two inclinations angle of going up

valve

6a, 8a can be identical or different.Therefore, two valve can carry out the rotation of same magnitude or different amplitudes.

Equally, the valve quantity that use is not limited to two, can use several valve in each side of nozzle, know, the blocking ability of valve is along with their quantity increases, but this has also increased the complexity of controlling organization.

It is equally clear, available other controlling organization moves axially nozzle, particularly can consider the mechanism that uses a gear and tooth bar type, gear and screw type etc. are arranged, or other can convert the rotation of circumference control loop to the axially movable mechanism of central nozzle.Also can consider the automatic controls of a this mechanism of starting.
