Description

A kind of energy-saving blowing method of Portable air purifier

Technical field

The present invention relates to field of air purification device, especially a kind of energy-saving blowing side of Portable air purifier Method.

Background technology

The pollution of air has expedited the emergence of the use of a large amount of mouth masks, but use portable air purifier and it is few because Existing various Portable air purifiers using and it is inconvenient, have plenty of effect and bad, also be wear it is very uncomfortable, It is too short to have plenty of service time of battery, has plenty of because being difficult to see to be difficult to be popularized, then present applicant has proposed application number For 2016208328930 earlier application《A kind of rear-mounted respirator with air purifying function in head》, hereinafter referred to as：《It is rear-mounted to exhale Inhale device》, there is big filter area, belong to without electric drive can also normal use air cleaning unit.

Most of Portable air purifier on the market or the air purifier blown using electric drive at present, are had Using effect it is bad, but no matter using effect how, have one it is critically important the defects of be exactly battery cruising time it is too short, We bought it is a lot of carry out actual use test, be essentially all that can nominally use 3 to 5 hours or 8 to 12 hours, but It is to be substantially all the highest time for being difficult to reach nominal, has typically just reached nominal minimum time, some air supply ducts Too long of arm belt, battery capacity more greatly, but need power of motor it is also big, have plenty of face wearing, power of motor phase To a little bit smaller, because size is limited by space, battery capacity also very little.

The characteristics of having one jointly is exactly that current all these Portable air purifiers are all continuous blowings, this The continuous continual air-supply of sample both influences battery life, can also influence the service life of filtering material.And actually people Breathing is intermittent, and adult one minute typically 12-20 times, children are general 20-30 times, it will be apparent that respiratory is substantially all It is three steps：Air-breathing, expiration, pause, general inspiration time constitute about 35-50% of breathing duration or so, there are about the electricity of half or so The service life of amount cruising time and filtering material is wasted.

Also an apparent common trait is exactly all small air purifiers, especially portable including these Air purifier, the brushless quiet fan entirely used, i.e., all it is that outside is Magnmet rotor, is encouraged by Inside coil winding The motor of magnetic, this micromachine is because be brushless, and general service life is very long, and stability is good, and technology maturation, cost is low, So brushless motor fan as use, is essentially all method current in the world.

These small size air cleaners include the flabellum diameter that typically uses of portable air purifier be all 25mm with On brushless quiet fan, Portable air purifier is substantially 25-40mm centrifugal blower formula or leafy bobbin stream Formula is brushless quiet fan, the general several rated voltages of 3V, 3.3V, 3.7V, 5V, 12V are less using two batteries 3V, power It is essentially all in more than 0.5W, it is seen that accomplish it has substantially been that the power of formula air cleaning unit is worn in the face of minimum There are specified 3.7V, 0.5W.

The above-mentioned method that these use brushless quiet fan continuous blowing, it is essentially all that small size air cleaner is current The way of conventional form, it has been very ripe.So for many years, everybody does so, because these are all that technology is very ripe Pattern.

Very ripe, not representing has no problem.

Because the reason for the application, the applicant retrieved related application, Publication No. CN204364702U reality With new《A kind of face mask type air purifier》, a kind of air cleaning unit using batch (-type) air feed is disclosed, the patent is Will described in " control and touching is provided with electric breather valve 3 declines type control electric switch 31, circle round spring 32 ", from the specification and specification Accompanying drawing can be seen that the mask and only control electric breather valve 3 and inlet valve 4, " enters inlet valve described in specification final stage, enters Enter mask cavity, be diffused into the oral cavity of user, nose realizes the purpose for purifying air.Power supply is continuously powered, cavity pressure When power is excessive or exhales, outlet valve is opened, and touching formula control electric switch is opened, and lithium battery power supply device stops fan and provides electricity Power, blower fan are stopped, and air stops passing through air inlet air inlet clarifier, mask cavity, and pressure differential reduces, and outlet valve closes Close, outlet valve power control switch closure, lithium battery power supply device start again fan power " whole service mode can be clear Find out to Chu, the electric breather valve 3 of control described in it is exactly to be mounted with that the touching declines type control electric switch 31 at described outlet valve Breather valve 3, that is, breather valve described in general mouth mask also has referred to as outlet valve, and only address is slightly different, Contribute to the check valve of exhaled gas, simply added on the basis of these one-way breather valves with touching decline type control electricity The outlet valve of switch 31, that is to say, that the breather valve in the patent is exactly outlet valve, is same meaning.

It is obvious that the patent is by the increased pressure in mask cavity, i.e. malleation or perhaps mistake of exhaling when exhaling Press the outlet valve washed open, outlet valve is opened simultaneously and touching formula control electric switch is opened, so as to power off because outlet valve be Just to be opened during exhaled positive pressure, that is, malleation when exhaling to switch off, and blower fan is stopped, because all outlet valves Diaphragm is all outward opening, also can only be outward opening, and the type control electric switch 31 that declines is touched described in the patent and is installed on breather valve Place, so the outlet valve is just opened when also can only be and exhale, that is, switch off.

That is, controlling blower fan to be stopped when the patent passes through expiration, disconnected when being and exhaling.

After disconnecting upon exhalation, " blower fan is stopped, and pressure differential reduces, outlet valve closure, outlet valve power control switch Closure ", it is off pressure after exhaling and declines, that is, stop switching closure after exhaling.Blower fan stops when that is exhaling, and stops exhaling During gas, blower fan is started working, i.e. is expiration control mode.

One it is obvious the fact, when people breathes under general state, expiration, respiratory standstill, air-breathing duration accounting in, exhale Gas only accounts for the time less than 20-25% or so, and respiratory standstill will account for for 40% or so time, if controlling party as using Formula, the even patent can be implemented, and energy-saving effect there will not be too many raising.

In addition, there is the person skilled of product or experience in design it is apparent that the fortune of the patent application Line mode is substantially unworkable, seems very simple, is difficult to realize in fact.

This operation logic is with regard to problematic.Start is turned on the power switch, blower fan work, " power supply is continuously powered, cavity pressure During excessive or expiration, outlet valve is opened, and touching formula control electric switch is opened ", that is to say, that it is not only mask sky upon exhalation Cavity pressure is possible to rise, and washes breathing valve film open, and power-off, blower fan stops, it is also possible to which " power supply is continuously powered, cavity pressure It is excessive ", i.e., blast can washes breather valve open caused by blower fan work.

First say at first point, " the excessive outlet valve of cavity pressure is opened ", if do not exhaled, blast energy caused by blower fan work Enough wash breather valve open, then, breather valve is opened, and power-off, blower fan can be stopped, and pressure declines, and breather valve closes energization, wind again Machine works, and pressure rises, then powers off, and blower fan stops again.If probably due to pressure declines in breathing process, breather valve closure It may be because that pressure rises and blower fan can work on, during expiration, breather valve is opened and blower fan is stopped, and still, is being exhaled Inhale this overvoltage when pausing just occur it is such start repeatedly, do not have the effect of intermittent energy-saving.

Besides second point, " during expiration, outlet valve is opened ", power-off, blower fan is stopped, if stop exhaling, breathing Valve closes, and has just been returned to above-mentioned first point mistake.If stopped after exhaling, breather valve is still opening, it may be possible to occurs Failure or design mistake, if stopped after exhaling, breather valve closure, blower fan in continuous firing, can only illustrate that blower fan produces certainly Blast be less than the pressure of breather valve unlatching, could normal operation.So the patent is probably the convolution with the breather valve Spring 32 adjusts the pressure in mask cavity, but does not illustrate, can only speculate, and can only be by the spring 32 that circles round Pressure causes the Opening pressure of breather valve to be more than the pressure of blower fan.

Just not saying the convolution spring 32 described in this is just difficult to play a part of regulation at all, this convolution is first supposed Spring 32 enables to blower fan normal work after expiration, i.e. pressure is more than wind caused by the convolution spring 32 of the breather valve Blast caused by machine, also can only be so could normal operation, then, the time that blower fan is stopped at most be exactly exhale when Between, i.e., the time that interval stops only has 25-30% or so time, is typically got in 0.8-1s or so, the time that batch (-type) pauses Short, the effect of energy-conservation is poorer, extends the cruising time of battery not over 25%, is damaged plus the starting current of blower fan frequent starting Consumption, not over 20% or so, if designed plus the long pipe runs of the patent, energy-saving effect can also be lower, if blower fan is not from Rationally, almost any energy-saving effect can not be had certainly, of course, because blower fan is all working in respiratory standstill, also It is not necessary to consider the startup response time of blower fan.And this still must be being established can be on the premise of normal operation Effect.If under the motion state of fast respiratory rate, although expiratory duration accounting increases to 40-45% or so, but breathe frequency Rate is too high, and more than more than 30,40 times, startup is too frequent, for the air-breathing apparatus of general brushless Jing Yin motor, Without the necessary of periodic running.

So this be and unpractical by way of controlling blower fan periodic running exhaling, it might even be possible to is to say It is wrong.Certainly, for the structure design of the patent, controlling switch is placed on breather valve, i.e., actual unidirectional row It is obvious method at air valve.

Later say again, by the convolution spring 32 in actual production and in use, being difficult to play the work of regulation at all With because using battery, just not saying the patent does not have control function, even having, no matter how to control, battery is different Cruising time section, blast all can be different caused by blower fan work, returns at above-mentioned first point, if the convolution spring 32 Pressure is smaller, just occurs that fan pressure is excessive caused " cavity pressure is excessive ", and above-mentioned respiratory standstill period frequency just occurs The problem of numerous startup；If the pressure for the spring 32 that circles round is smaller, and blast caused by blower fan is more than convolution spring 32 and adds air-breathing Pressure, even just occur in air-breathing also can frequent starting the problem of, thus influence whether normally to breathe；If The pressure of convolution spring 32 is too big, even just occurring when exhaling, the state that blower fan will not also be stopped, may breathe out Gas leaks from mask perimeter.

Even have again be exactly same person in the state of difference, malleation caused by breathing and negative pressure all can be different, and And people exhale and air-breathing caused by pressure it is inherently little, our all used breather valve mouth masks, that very simple circular membrane Piece breather valve, sometimes all rushed not open in general exhale, all people can be allowed to feel uncomfortable, although the possibility that the patent uses Be sealing mask, but this convolution spring 32 caused by pressure be difficult the different breathing states and battery of suitable people simultaneously not The same time, pressure it is too big and it is too small can all allow people uncomfortable, pressure is too small to be also difficult in adapt to all breathing states and battery continues Endurance section, in addition also different people, not think and seem very simple spring pressure adjustment, it is important to caused by this blower fan Blast has no idea to control for the technical scheme of the patent.

So above-mentioned patent practicality is than relatively limited in fact, certain logic error be present, energy-saving effect is not yet Height, therefore have very big change space.

The content of the invention

The problem of for above-mentioned existing product, and the defects of referenced patents, the method applied in the present invention, for portable For formula breathing equipment, it may be said that be entirely subversive.

All it is the convention of continuation air-supply for above-mentioned conventional air purifier, the present invention will be sent using batch (-type) first The method of wind is solved, with reference to foregoing earlier application《Rear-mounted breathing equipment》, and the Application No. of earlier application 201621073072X's《A kind of breathing equipment spiracle diaphragm type touch switch》Spiracle diaphragm type touch switch, A kind of interval implemented the energy-saving blowing method based on a kind of Portable air purifier of the present invention and implemented is blown The rear-mounted respirator with air purifying function in head, and with the interval air-supply the rear-mounted respirator with air purifying function in head reality Apply to help to illustrate the method for the present invention：

A kind of rear-mounted respirator with air purifying function in head of batch (-type) air-supply, including at least main body cover, conduit part, nose cup Portion, ear-hanger, fan, battery, the main body cover include outer chamber, inner chamber body, casing cover, and the outer chamber, which is used to store, to be rolled over The conduit part of poststack and nose cup portion, the inner chamber body are at least provided with filtering material, battery, fan, and the conduit part can be entered Row is flexible or folds, and the nose cup portion has spiracle at nostril, steam vent air bleeding valve, the air inlet connected with conduit part, institute Stating at spiracle has edge sealing sealing ring, the nose cup portion air inlet connecting tube portion, and the conduit part air inlet connects main body Air outlet of casing, the conduit part air inlet can be folded or rotated, it is characterised in that：The power drive system of the breathing equipment Using periodic running pattern, there is touch switch at nose cup portion spiracle, at the main body cover air outlet or conduit Portion is provided with fan, and when people is in air-breathing, spiracle inspiratory airflow touches touch switch so that the fan brings into operation, and stops Touch switch reduces when air-breathing or expiration, and fan is out of service.

Because particularity of the present invention from the face structure of example, in order to prevent because word is identical and caused by understand it is wrong By mistake, the passage of the enough air-breathings of the and can that can either exhale is named as spiracle by the present invention；In order to distinguish, one-way exhaust valve will be installed Gas outlet is named as steam vent or exhaust outlet, and one-way exhaust valve is named as air bleeding valve, and this air bleeding valve is essentially identical to conventional breathing The one-way breather valve of valve port cover or air cleaning unit, or outlet valve is, that is, the breathing described in above-mentioned referenced patents Valve and outlet valve；Inlet channel is named as air inlet or air admission hole, is installed on the intake valve that cries of air inlet, the applicant is first Multiple patent applications for being related to nose cup of application are all so defined.

Fig. 1 show the example 1 of the present invention, and this example 1 is based entirely on the earlier application《Rear-mounted breathing dress Put》Embodiment on the basis of, add power drive system part, it is intended to further improve described in《Rear-mounted breathing equipment》Make Comfortableness, although foregoing first to file《Rear-mounted breathing equipment》Using big filter area, respiratory resistance is relatively It is small, the purpose of air filtering can be reached by autonomous respiration completely, but still have certain respiratory resistance after all.

Therefore, power drive system theory proposed by the present invention and existing Portable air purifier are all different, Existing Portable air purifier is mainly that active Wind Volume is blown, the method continuously and uninterruptedly blown, and this The mode that invention is then preferentially blown using assist type, the method for air-supply is mainly for resistance caused by counteracting breathing For the purpose of, the air output that can be so designed as air quantity compared to existing Portable air purifier is smaller, can use phase To the motor of smaller power, in the case where not influenceing the major premise of comfort and filter effect, to realize maximized saving electricity Can, extend battery life.

Fig. 1 show foregoing earlier application《Rear-mounted breathing equipment》Embodiment be agent structure exemplary plot, it is described Agent structure has main body cover 1, and the main body cover 1 has outer chamber, for storing the He of conduit part 6 after folding or retracting Nose cup portion 7, there is inner chamber body, for installing driving member and filtering material, there is casing cover, the filtering material and outer These are ignored in cap, outer chamber, this explanation and Figure of description and not indicated, is because all in earlier application《It is rearmounted Formula breathing equipment》In have associated description and mark, be not the dominant features of the present invention, this explanation is in order to sketch, not generation The not no part of table；The agent structure has nose cup portion 7, and the nose cup portion 7 has spiracle and spiracle sealing ring 70, exhaust Hole air bleeding valve 71；With conduit part 6, the center section of conduit part 6 have it is scalable or can bending structure, with main body cover 1 Bound fraction has can horizontal bending or flexible connection inner casing 61 and connected with outer casing 62；With the support for back side of head part Pad 11 and the ear-hanger 12 for hanging over ear position.

As shown in figure 1, in the earlier application《Rear-mounted breathing equipment》On the basis of embodiment primary structure, by before The diaphragm type touch switch 81 for stating earlier application is installed at the spiracle in nose cup portion, and this example 1 opens the diaphragm type touch-control 81 design and installations are closed at exhaling hole, is between the spiracle in nose cup portion 7 and sealing ring 70, is directly in outside nostril, it is described Touch switch is not restricted to the diaphragm type touch switch 81 described in foregoing earlier application, can also be other patterns certainly Controlling switch, the present invention controlling switch is directly mounted at the spiracle of nostril mouth, directly can be exhaled by nostril Or air-flow caused by air-breathing blows the axle dynamic diaphragm of diaphragm type touch switch 81, most most promptly directly can effectively link soon The touch-control part of the diaphragm type touch switch 81, is controlled electrical drive portion of the present invention in real time, be most directly, Rapidly, effective method.

As shown in figure 1, electrically driven (operated) major part of the present invention is installed in the inner chamber body of main body cover 1, including wind Fan 21, battery 51, control module 31, and it is installed on the indicator lamp window 45 of the shell wall upper surface of main body cover 1, Micro-touch switch 43rd, charge bayonet socket 41.

This example 1 will use more commonly used 3.7V or 3.3V charged lithium cells 51, can be according to the rear-mounted air The difference of the pattern construction size of breathing equipment is purified, to select the capacity of battery, because main body cover of the present invention 1 is in Back side of head position, relatively large space is can be designed as, this large space advantage even can according to existing polymer battery With using more than 4000mAH high capacity cell, it is contemplated that be worn on the weight factor on head, preferably 1500-3000mA or so .

This example 1 is using conventional 2506 i.e. flabellum diameter 25mm or so brushless quiet fan, naturally it is also possible to selects Other specifications of 20-40mm series, are different according to style, from turbine centrifugal fan or aerofoil fan, it is important to install Position to try one's best close to the position of the air inlet of the connected with outer casing 62 of conduit part 6, shorten the length of pipeline and multiple as far as possible Miscellaneous degree, reduces windage to greatest extent.

The fan 21 is installed at the air outlet of main body cover 1 by this example, the connected with outer casing in direct opposing pipe portion 6 62, the reaction time of wind-engaging at nostril is improved as much as possible, and this is extremely important for the solution of batch (-type) air-supply, directly closes It is the Consumer's Experience to user, is a meaning of the batch (-type) air-supply, of course, can also be directly by described in For fan design at the nose cup portion 7 in nearly nostril, such reaction speed is most fast, but the volume that designs may be needed too big, not The nose cup portion for being suitable for rear-mounted air cleaning unit of the present invention minimizes the original intention of design, and such embodiment will Separate case application can be carried out.

The basic operational mode of electrical drive portion of the present invention is to pass through the film being directly arranged at the mouth breathing hole of nostril Chip touch switch 81 is controlled the power drive system in real time, passes through air-flow direct pull diaphragm caused by the air-breathing of nostril The axle dynamic diaphragm of formula touch switch 81 so that the contact closure of the touch control component of the diaphragm type touch switch 81, start fan Operation, is blown by conduit part 6 to nose cup portion 7, and the air that nostril therefore can easily after suction filter, unnecessary air leads to The air bleeding valve 71 for crossing steam vent is discharged, thus the present invention tend to using only need offset respiratory resistance it is relatively low The air quantity way of output, i.e. assist type air feed theory, the cruising time of battery can be extended to greatest extent, extend making for filtering consumptive material Use the life-span.

When stopping suction, just reduced at nostril without air-flow, the axle dynamic diaphragm of touch switch 81, this example institute State diaphragm type touch switch 81 and use normally open, will disconnect naturally.Certainly, due to people in air-breathing it is latter as time for pausing Very short, typically meeting horse back exhaled gas, air-flow caused by expiration also can directly cause the reduction of touch switch 81 to disconnect, fan It is stopped immediately.

The inspiration time of common people is less than the duration exhaled with respiratory standstill, typically 4:6 or so, therefore the present invention uses Periodic running method can save a part of electricity, and be directly mounted at the touch switch 81 at nostril and can cause electricity Drive system is more rapidly made a response, if system response is blunt, can be produced breathing vapour lock break, can be allowed user Feel not very comfortable, will greatly reduce the use feeling of user, it is clear that will greatly reduce the work of periodic running mode With and meaning, or even do not have effect.

Other operational processes are substantially more traditional, and this example 1 touches micro-touch using film key Micro-touch switch 43 The start of switch 43, is controlled by module 31, could be arranged to by 1 next grade of air quantity, by 2 times two gears, is shut down by 3 times or by 3 Lower three gear, by 4 times shutdown.When electricity is less than certain value, for example 3.7V discharging rechargeable battery voltage is down to 2.8V blanking voltages When, by indicator lamp window 45 it can be seen that when red, instruction needs charge, and charging socket 41 switches on power adapter, leads to Cross control module 31 to charge to battery 51, battery is full of indicator lamp display green.

In fact, the continually startup and stopping of batch (-type) are done, the fan of many Portable purifiers is not to be suitable for, Using periodic running mode compared with the continuous schedule method of operation, the such as 40mm of effect and unobvious, especially major diameter is straight The turbine radial fan of the blade of footpath 31, specified 3.7V, 0.8W, vane rotor have reached 7.6g or so, energization 1.3s, power-off 1.7s, i.e., respiratory rate 20 times, starting current have reached more than 350mA, and the reaction time more than more than 100ms, reaches most strong wind Speed is even more than 0.3s or so, not suitable for periodic running mode, extends cruising time only using periodic running Have 50% or so, the electric current that more frequently high current starts consumes, and will accordingly reduce the effect of periodic running.And equally adopt With 40mm diameters, but it is the brushless quiet fans of axle stream of page 7, specified 3V, 0.6W, vane rotor quality 4.8g or so, breathing frequency Rate 12 times, this is the relatively low frequency typically breathed, and energization 2s disconnects 3s, and starting current in 350mA or so, can also increase Cruising time 110% or so, that is, 2 times or so are extended to, as respiratory rate increases the cruising time extended less than 1 times.Survey The fan that formula air cleaning unit 3.7V, 0.4W is worn in a minimum face is tried, energization 2s, disconnects the situation that 3s low frequency time breathes Under, it can accomplish at most to increase the best effects of 140% continuation of the journey duration.

Therefore, it is that can play obvious effect so using periodic running, but not all air is net Makeup, which is put, to be suitable for, and is not that continuous schedule simply is changed into batch (-type) can, from suitable light rotor, low-power, height Efficiency can play corresponding effect.

Portable air purifier will use periodic running mode, the preferably present invention or the brushless Jing Yin wind of below 40mm Fan, as shown in figure 1, this example 1 use the 2506 brushless quiet fans of axle stream, specified 3V, 0.3W because such conventional shaft stream without The design limitation, root diameter 23mm or so of brush quiet fan, middle n omicronn-leaf section diameter just has 16.5mm or so, rotor quality 2.1g or so, blade very little, air quantity also very little, can only improve rotating speed, rated power is brought up into 0.5W just certain effect, Periodic running actually preferably can only also increase to 2.1 times or so.

In order to maximumlly improve the effect of intermittent operation, various equivalent modifications are it is envisioned that preferably not The brush-less fan of existing corresponding size is directly purchased, it can easily be shown that customization die sinking design brush-less fan again And flabellum, on the basis of existing brush-less fan, rotor internal diameter can be designed to it is somewhat a little bit smaller, using strong magnetic rubidium magnetic Iron, in the case where meeting the principle of flabellum intensity, rotor is included into the more frivolous of flabellum design, such as 2.1g 2506 models Fan propeller can accomplish below 1.5g, above-mentioned 4.8g's can reduce half weight, can so improve response speed, drop Low starting current, it can further improve the effect of periodic running.

According to the design needs of the space size of different styles, the aerofoil fan 21 can also be changed into radial fan, If different according to respiratory rate using 3004 radial fans of the following linear leaf of 17 blades, cruising time 80%- can be extended 140% or so, i.e. cruising time extends to 2.4 times or so.

These are brushless quiet fan is when battery discharge arrives 2.8-2.4V or so, and fan wind-force is very faint, just Operation is lost to act on.

It is above-mentioned portable air purifier is changed to batch (-type) air supply pattern using traditional continuous air feed pattern to carry High 0.5-1.5 times of battery life, original 2.5 times are namely at most typically extended to, can be by the performance of existing equipment 2 times to 2.5 times are promoted to, one kind innovation well should be deserved to be called certainly, if such transformation is a kind of fine Innovation if, then, the method below the present invention definitely deserves to be called a kind of subversiveness innovation.

Above-mentioned air purifier, including current all air-breathing apparatus, virtually all it is the brushless of use Quiet fan, before said, the stator of this brush-less fan is coil windings, and rotor is that flabellum adds built-in magnet common Composition, if as the working method continuously run, it is best selection that such brushless quiet fan is sure, technology Maturation, working stability, cost are low, still,, can very great Cheng as above-mentioned 7.6g, 4.8g rotor if to be used as periodic running Response time and the starting current of motor are had influence on degree, so as to have influence on the experience of periodic running and effect.

Motor of the example 2 of the present invention using subversiveness using hollow-cup motor as fan.

Using motor of the hollow-cup motor as the Air Blast fan of air-breathing apparatus, especially portable air breathing dress The fan put uses micro hollow cup motor, and this method is the side that impossible use in air-breathing apparatus design production field Formula.

Because such hollow-cup motor is all high-speed electric expreess locomotive, it can be seen that be generally used for nursing, model plane etc. Industry, more than 10,000 turns of rotating speed, especially popular unmanned plane, rotating speed are generally up to 30000-50000rpm now, and height turns For speed along with ear-piercing sound, general noise is very big, so general air purifier will not use certainly, and it is traditional brushless quiet Sound fan, general rotating speed all only have thousands of turns.

Importantly, such hollow-cup motor, especially small-sized hollow-cup motor, are essentially all brush motor, Brushless hollow-cup motor is domestic at present not to have correlation technique also, and the price of import is very high, and below 12mm hollow-cup motors are current Also without brushless, even have price also can be high to surprising, and it is miniature have brush drag cup, price is but very cheap, but because micro- Type drag cup is high-speed electric expreess locomotive, and is the motor for having brush, and brush is very thin, so service life is not grown, much for nothing Man-machine 7mm, 8mm hollow-cup motor, 100 hours having, or even be eliminated for tens hours, and brushless quiet fan Service life be up to tens thousand of hours.

Therefore, as need steady operation, long-time failure-free operation air-breathing apparatus, nobody can select to use The hollow-cup motor of such low service life, once extensive break down, deathblow can be caused to product and brand, Whom dares to risk so big risk without, therefore nobody dares selection using hollow-cup motor as the main of air-breathing apparatus Operative components.

But the present inventor is bold enough to do, this has no, it is only necessary to tells customer strictly according to the facts, this motor is very efficient, but uses the longevity Life is not high, is belonged to consumptive material, can easily be changed as changing battery, and change and also cheaply can very much With.This even needs to use the field of fan in air-breathing apparatus field including other in addition to model plane, is definitely anti- Conventional way, can be using the electric motor fan of critical piece as can be simple without which industry typically in addition to model plane field The consumptive material part of replacing, so, as field of air purification device, this can be very bold takes the plunge.

A design example of conveniently replaced drag cup fan 22 of the present invention is illustrated in figure 2, is adopted as far as possible With below external diameter 16mm micro hollow cup motor, it is preferred to use 6-12mm drag cup.It is illustrated in figure 3 point shown in Fig. 2 Schematic diagram is solved, the hollow-cup motor 221 and flabellum 225 are installed along with fan drum body 220 by this example 2, form institute Drag cup fan 22 is stated, this example will be illustrated using 612 drag cups.

The flabellum of matching with hollow cup is designed as 5 blade fans as shown in Figure 3 by this example 2, it is well known that in general wind Fan leaf is more, and operation is more stable, and noise is smaller, but blade more weight also can be bigger, matching with hollow cup of the present invention The design principle of flabellum is, on the premise of mechanical strength is ensured, accomplish as far as possible it is frivolous, by blade design to be as thin as possible, Blade shaft diameter is as small as possible.If the preferred 5-9 leaves blade of axial-flow type, if design runoff flabellum is preferably below 17 leaves.

5 valve leaf 225 shown in this example 2, blade rotor diameter 2.8mm, blade distal shaft end only need 0.2mm, can To accomplish 0.2g or so, or even 0.1g completely can be can accomplish to reduce the shadow to starting current and response time as far as possible Ring.And the rotor weight of 612 drag cups also only has 0.1g or so, that is to say, that flabellum adds the quality of rotor to accomplish 0.3g or so, or even below 0.2g can be accomplished completely, and the rotor of foregoing existing fan at least all in more than 2g even 7.6g, for periodic running pattern, the size for starting quality has bigger shadow to starting current and response time Loud, the power of general micromachine is all little after all.

Hollow-cup motor is used for the air-breathing apparatus, the present invention is not to bring just directly to use, for Drag cup is used for for intermittent operational mode, wants to optimize the advantage of drag cup, it should learn from other's strong points to offset one's weaknesses, exhale for air Device, especially portable air breathing equipment are inhaled, is sharp noise caused by high rotating speed the shortcomings that drag cup and relatively low Service life, but for periodic running pattern, because drag cup belongs to servo small and special electric machine, also have fit closely excellent Point, is just in response to that very fast, Energy Efficiency Ratio is very high, very light in weight, volume very little, as so the frivolous flabellum designed by the present invention Response time of low-load even can be more many soon than the general brushless quiet fan response time to below 20ms, this is right It is very favorable in the Consumer's Experience of user, and Energy Efficiency Ratio even can reach 90%, it is lower than general brushless quiet fan Energy Efficiency Ratio in 50% is many by force, and the cruising time of battery can be improved with conspicuousness.

And the quality of whole drag cup fan is less than 3g including flabellum, drag cup and blower-casting, and 40mm Quiet fan has 13g, and quality 10% can be reduced for Portable air purifier 100g or so quality, and this is also The notable sexual clorminance of hollow-cup motor, small volume, in light weight, convenient smallizationer design.

Fig. 4 show the drag cup fan 22 and fan deck 23, and 222 be that two wires of drag cup are direct in Fig. 3 The edge contact of fan drum 220 is weldingly fixed on, the correspondence position of fan deck 23 also has two band wire contacts 232, When changing or installing the drag cup fan, as shown in figure 4, the drag cup fan 22 is right towards the fan deck 23 Neck is answered to promote, the contact 222 just directly contacts with wire contact 232, and installation taking-up is all very simple and convenient, originally shows The wire that example 2 is designed as drag cup fan 22 is directly welded on fan drum, facilitates user directly to change, and will not be done anti- Direction, because flabellum is directive.The wire of hollow-cup motor can certainly be inserted into by pin terminal as shown in Figure 7 On the contact pin of control module, for a user obviously without such convenient, drag cup fan 22 and wind shown in this example 2 Fan the design of deck 23, it is only for the air cleaning unit that the convenient explanation present invention creates can be convenient for changing the solution of fan Certainly scheme, such scheme obviously can design too many style, the fan deck 23 can be single part or Directly it is integrated with the main body cover 1 injection.

Further, can solve service life by the solution of the changeable type drag cup fan shown in Fig. 4 to ask Topic, but these are clearly that passive type solves the problems, such as method, in order to most optimally learn from other's strong points to offset one's weaknesses, extend the service life of drag cup And maximumlly solve noise problem, on the premise of it disclosure satisfy that the theory of assist type of the present invention air-supply, can On the premise of ensureing air quantity, blast, this example 2 will be solved using reduction rotating speed or from the method for slow-speed of revolution drag cup, Rotating speed is reduced, can not only reduce certain noise, but also can obviously extend the service life of drag cup, so To increase the service life be a kind of active method.

Fig. 5 is shown only using an example 2 for 1 No. 5 batteries of section, only with No. 5 of a nominal 1.5V or No. 7 batteries, yes, 1.5V battery is only used, this is the method that any air-breathing apparatus is impossible to use, in general is brushless quiet fan 1.5V can not start at all, and the applicant uses one 612 or 610 hollow-cup motor fans, inspire confidence in 5 using 1 section millet or south Number battery, using continuous schedule operational mode also up to 46-95 hours, and air quantity is net unlike commercially available more money portable airs It is small to change the air quantity of device output, two No. 5 batteries of section use at twice can use 92-190 hours equivalent to accumulative, and we compared for Inspire confidence in No. 5 batteries for millet and south, and electricity is without what difference, substantially in 2200mAH-2400mAH or so, and uses commercially available portable Formula air cleaning unit, 3V power supplys are done with No. 5 battery series connection of two sections, total electricity is not less than 4500mAH, and continuous schedule is run minimum Can only use 8 hours, 10 hours or so air quantity of fan can not be operated completely with regard to very little, some, it is best and minimum Specified 3.7V, 0.4W's can reach 26 hours or so, and the battery capacity carried that this minimal face wears formula clarifier only has 3.7V, 250mAH, actual galvanic cell use can only use 2 hours or so, and it is all 3-5 hours that other moneys, which are used from charged pool, Wear-type currently without more than 5 hours.

General brushless Jing Yin motor will substantially shut down when voltage for 2.6V--2.2V, particularly charging electricity Pond, in order to protect battery, some blanking voltages are arranged to 2.8V and are just stopped, and some 2.4V are also being operated, but are not had substantially What air quantity, the effect as air purifier is lost, still, using hollow-cup motor, using No. 5 batteries of in general, It can still continue to blow when voltage 1.0V, although air quantity reduces, can also also meet proposed by the present invention auxiliary The needs for helping formula to blow, the 612 of the Ω of part end resistance 5 can even work to 0.85V, can almost make full use of and exhaust electricity All energy in pond, are that energy is maximally utilized, and this is that brushless electric machine can not possibly be accomplished, these brush-less fans stop fortune After row as many as tens hours, the advertising words that south is inspired confidence in can also be used using drag cup：The battery remote control that telecar is finished is also It can then use, be well suited for both motors.

It is single that conventional brushless quiet fan is only changed to hollow-cup motor fan, only with traditional continuous service pattern, Cruising time can at least lifts more than 3.5-20 times, inconceivable.

The light source of the liquid crystal display display screen behind of early stage is all the fluorescent tube of the entire row one by one used, is all adopted now Justifying LED light source, before this is like no LED, all it is the incandescent lamp or fluorescent lamp used, is provided to light, but LED energy-conservations are very significant, are definitely subversive, and same brightness, using LED and incandescent lamp Energy Efficiency Ratio, and will Reach same air quantity, using the Energy Efficiency Ratio of drag cup and general brushless Jing Yin motor, both Energy Efficiency Ratio it is similar, therefore, It may also be said that it is also subversive to be used for air cleaning unit using drag cup, therefore, use industry complete air-breathing apparatus The hollow-cup motor that can not possibly be used entirely, definitely it is a kind of being bold in innovation for anti-convention.

Further, the drag cup fan is used into periodic running mode of the present invention, using No. 5 electricity of section Pond, energization 2s, 3s is powered off, i.e., run using the normal respiration indices frequency of comparison of 12 times of breathing in one minute, during energization Long accounting 40%, whole respiratory cycle duration are switched on 2.5 times of duration, using 612 and 610 drag cup fans, run eight daily Nine hours, No. 5 conventional alkaline battery cans of a section reach or so mysterious 140-230 hours, this duration by The influence of drag cup end internal resistance is different, if two batteries, accumulative cruising time can reach 280-460 hours, quite 2.5-3 times or so of continuation of the journey duration is run in continuous schedule, alreadys exceed 2.5 times of multiplying powers of breathing duration and energization period, this is It is that battery is maximally utilized because intermittent electricity consumption is more beneficial to battery back pressure.And tested with same respiratory rate, together Sample is connected into 3V power supplys using two No. 5 batteries of section and tested, and continuous schedule operation can run 8,10 hours brushless quiet fans Only run 18,22 hours just it is out of service, at most only 2.2 times or so because the startup of brushless quiet fan Electric current is big, and response time length, startup consume is more much older than drag cup, and some turbine fan Energy Efficiency Ratio are relatively low, if logical Electric time length ratio is maintained at 40%, and increase respiratory rate is to 20 times, and multiplying power only has 1.5-2 times or so after delay, well below breathing week 2.5 times of multiplying powers of phase duration and energization period.

Moreover, when breathing rate is more than more than 30 times, using brushless electric machine without the necessary of periodic running, Continuous service pattern is readily modified as, but because the drag cup response time is very short, can still continue to use periodic running pattern.

The simplest solution of the rear-mounted respirator with air purifying function in interval air supply pattern head of the present invention, just It is mono- spiracle diaphragm type touch-control of No. 5 battery 52+ for only needing the sections of drag cup fan 22+ mono- 1.5V as shown in Figure 5 Switch 81, directly connected together with the Micro-touch switch 43 controlled manually, it is possible to use with most simply realizing overlength continuation of the journey Portable air purifier of the present invention, eliminate conventional portable air purifier and charge for one day one, if one It is only used 8 hours, or even needs the worry of charging in one day two, and the drag cup batch (-type) air-supply that example 2 of the present invention uses solves Scheme, 8 hours one day, it can accomplish to change a batteries or so fortnight completely, yes, you do not misunderstand, a batteries, and two Individual week, or even 3 week, it might even be possible to allow user to forget to change battery.It is this simplest all using batch (-type) confession The mode of electricity is named as：One section of full intermittent power supply pattern.

Contrast is understood, if contrasting the lasting fortune of existing air cleaning unit using periodic running pattern according to the present invention Line pattern, operation contrast is carried out using identical electricity, continuation of the journey duration be 11-50 times of these existing Portable purifiers with On.

Further, performance can also further be lifted, acceptable example 3 as shown in Figure 6, is in described Fig. 5 Increase control module 32 on the basis of shown simplest example 2, by control module 32 to whole electric drive supply air system Carry out certain control.

According to the feature of the hollow-cup motor, and it is of the present invention it is main it is preferred with assist type blow based on reason Read, according to different design models, style and the corresponding control setting of crowd's progress being directed to.Common people are in slow breathing state Under, such as the slow breathing state such as sit quietly, be careful, because the Energy Efficiency Ratio of drag cup is very high, if using below the Ω of end internal resistance 40 Drag cup, preferred 4-20 Ω or so drag cups export 1.0V-1.5V, and preferably 1.0-1.3V or so voltage is substantially enough Normal use under slow breathing state, end internal resistance is lower, and the voltage of voltage stabilizing output can also be lower, in fact 4.5 Ω ends internal resistance Drag cup, the voltage stabilizing value of output be arranged to 1.0V outputs caused by air quantity can also all meet under in general slow breathing state Demand, or even 0.9V or so can, this is that brushless quiet fan is difficult to, and general high-quality No. 5 or No. 7 batteries Most of initial voltage be all higher than 1.6V, if be not controlled to cell output voltage, simplest fortune as described in example 2 Line mode, initial air quantity can be larger, and follow-up air quantity can be reduced gradually, and so unstable air quantity can have necessarily to Consumer's Experience Influence.

This example 3, which is designed as the control module 32, has voltage stabilizing output module, can according to different styles, using pair As, using actual conditions such as the hollow-cup motor of different internal resistances and the different scenes that use, exported after different voltage stabilizings is set Magnitude of voltage, can by this setting output magnitude of voltage be named as：Voltage stabilizing output voltage, the magnitude of voltage of the voltage stabilizing output is also Can set and export different multistage voltage stabilizing output voltage, for example, with 1 section 1.5V batteries can also multi-level output 1.15V, 1.20V, 1.25V, 1.30V, 1.35V etc. different voltage stabilizing output voltages, it can be improved within the longer time of battery durable The running stability and controllability of power drive system.Of course, be actually needed according to actual scene, for example, can also by 3.7V or The voltage stabilizing of 3V batteries exports such as above-mentioned multistage voltage stabilizing output voltages of 1.15V-1.35V, can also set output such as 2.8V, 2.6V, The multistage voltage stabilizing output voltage such as 2.4V, according to the design needs depending on, it is not limited to the sample data.

This example 3 can preset the minimum input voltage threshold value for the battery for carrying out voltage stabilizing output to Voltage stabilizing module, by described in The minimum voltage threshold value of battery input is named as：Minimum voltage stabilizing input voltage, the minimum voltage stabilizing input voltage can be higher than Voltage stabilizing output voltage can be less than, for example voltage stabilizing output is carried out to 1 section 1.5V batteries, the voltage stabilizing output voltage of setting is 1.15V, Minimum voltage stabilizing input voltage is 1.0V even 0.9V.

Certainly, the control module 32 can also be controlled and can implemented to output current by current-limiting circuit 's.Actually 1.2V, 33mA power, i.e. rated power 0.04W can just meet normal use under slow breathing state completely, Even 1.0V, 30mA, i.e. 0.03W are also possible that therefore drag cup fan of the present invention, substantially only need above-mentioned production 1/10 or even 1/30 power of the brushless quiet fan of product can meet the design requirement of the present invention, pass through current limliting 30- 40mA can also meet the corresponding demand of portioned product, although voltage stabilizing output can lose 2% or so electricity, early stage passes through control Voltage voltage stabilizing processed can extend cruising time 25% or even 50% or so on the contrary to 1.2V or so output.So, it is of the present invention The cruising time of drag cup fan periodic running pattern will carry compared to the cruising time of existing Portable air purifier Height arrives 15-75 times or so.

It has been just very outstanding innovation that 50%-100% can be lifted by properties of product by, which being improved when one, and the present invention carries Several times of an even magnitude for a magnitude have been risen, subversive innovation can be deserved to be called completely.

When the voltage exported by Voltage stabilizing module is reduced to the voltage stabilizing output voltage of setting, such as during to 1.15V or so, The rated voltage 3.3V-5V of the general model plane of rotating ratio of hollow-cup motor has wanted small a lot, and rotating speed can be reduced to Within 6000rpm, rotating speed can drop to 1/3 or even 1/10 or so, and the service life of drag cup has also accordingly obtained very big carry Rise, by test, with 1.5V continuous service 6mm hollow-cup motors, be generally all up more than 3000 hours, it is general with 1.2V operations It can accomplish not having to change using more than 1 year, this is low to ask service life of the hollow-cup motor for air-breathing apparatus One active strong lifting of topic.

Further, when exercise intensity improves, gear can be lifted by pressing Micro-touch switch 43, for example press one again Down or two get off to lift one grade or two grades, the output of one grade or two grades of voltages or electric current are lifted by control module 32, to be lifted The rotating speed of hollow-cup motor.

Further, in order to improve convenience and comfortableness, this example 3 is by the real-time respiratory intensity need according to user Ask, air output is improved using the automatic method for improving motor speed, this example 3 is opened using more stationary contact Multistage Control formula touch-controls Close, motor speed is improved by the voltage or electric current of the output of multistage touch-control automatic lifting, to improve wind speed and blast.

Foregoing spiracle diaphragm type touch switch 81 switchs for single stationary contact, and this example 3 uses 3 static contacts totally 5 The spiracle diaphragm type touch switch 82 that multistage can be automatically controlled of more stationary contacts of gear, i.e., the dynamic of described touch switch 82 touch Body has 1 moving contact a, and stationary contact body has 3 static contacts b, c, d, respectively link control module 32 pin, as control The trigger point of molding block incoming level, one grade is triggered when moving contact a contacts static contact b, when moving contact a touches stationary contact simultaneously Two gears are triggered during head b, c, the gear of triggering four when being kept off when only contacting c for triggering three, while contacting c, d, five grades of triggering when only contacting d Or acquiescence output ceiling voltage, i.e., described touch switch 82 are the three more stationary contact Multistage Control touch switches for touching five grades.

The speed of the inspiratory airflow of spiracle when passing through air-breathing, the axle dynamic diaphragm of more stationary contact touch switches 82 can make it that Different angle is rotated to, linkage touches different static contacts to moving contact a successively, so as to which trigger control module is made accordingly The lifting step by step of voltage or electric current, reach the purpose for automatically controlling air quantity output.Of course, because hollow-cup motor inherently has There is certain servo characteristic, can also more smoothly change air force by using DC frequency-changing, but cost can be higher, due to Using three 5 grades of gear shift modes for touching five grades, velocity variations also can be actually such to touch step by step than smoothly for example 3 of the present invention Hair is also very simple for control module, is controlled step by step as the single-chip microcomputer can solution of more than ten very cheap of pin Mode processed.

Five grades of output controls can allow people to feel pleasant enough, and certainly, touch switch 82 can also use 2 stationary contacts The solution of first three gear, i.e., two touch three gear controls, more relatively easy, also disclosure satisfy that certain requirement, it is clear that can also Design more than more ranks, such as 7 grades controls etc..

Certain, because the touch switch not necessarily have to can be directly used in series as the switch of fan, also It can be used as the triggering level of control module, therefore the touch switch and not mind switch designs for normally opened or normally closed shape State, the design and installation of so more convenient touch switch.Of course, trigger signal of the touch switch preferably as control module Source uses, and also can uses other can be with gradual control or the side of Linear Control to the Multistage Control formula touch switch Method, such as pulse signal, swept resistance formula, adjustable capacitance type etc., it can make as the level triggers signal of control module With these various forms of trigger signal sources also can be understood as more stationary contact Multistage Control touch switches, the application For convenience of description, it can be uniformly interpreted as touch switch.

Of course, after can also be by touch switch triggering level signal, be become by control module to motor output speed Change softer sine-wave current, trapezoidal wave electric current, or the rectangular wave electric current of two sections of voltage, it is also possible that motor operation is more Soft smooth-going, naturally it is also possible to the purpose of adjustment air quantity can be also readily implemented using micro-step motor.

Further, in order to carry out more rationally significantly more efficient efficiently utilization to the power drive system and battery, This example 3 will use multi-segment voltage output mode：Three-stage powering mode.

First paragraph is to export electric current of voltage regulation by Voltage stabilizing module, when cell voltage is more than minimum voltage stabilizing input voltage, Control module 32 exports voltage stabilizing output voltage by Voltage stabilizing module, and the minimum voltage stabilizing input voltage is arranged to by this example 3 1.0V, it is 1.1V to set voltage stabilizing output voltage, i.e., it is defeated all to export voltage stabilizing by Voltage stabilizing module when cell voltage is in more than 1.0V It is 1.1V to go out voltage.

Voltage stabilizing output voltage 1.1V described in this example and minimum voltage stabilizing input voltage 1.0V, the only example of example Value, it is clear that it can also need to be configured according to actual scene, for example it is 1.2V that can also set minimum voltage stabilizing input voltage, very To being 0.9V, for example voltage stabilizing output voltage could be arranged to 1.0V, or even directly voltage stabilizing output voltage is 1.5V.Certainly, for Rechargeable battery 3.7V or 2 batteries 3.0V, can be designed according to practical application scene needs and sets, for example sets minimum steady Pressure input voltage is 2.6V, and the voltage stabilizing output voltage of output is 3.0V, therefore can be set according to actual conditions, however it is not limited to this Voltage threshold described in example.

Second segment is directly to motor output current, when cell voltage drops to minimum voltage stabilizing input voltage by battery During 1.0V, control module 32 switches to the powering mode of motor directly to hollow-cup motor current mode output, while is referring to Show that lamp window shows the instruction of low-voltage blinking red lamp, for example 1 second 1 time is reminded to show.All adopted under first and second section of powering mode With periodic running pattern.

3rd section is fan electromotor continuous service pattern, when cell voltage is less than certain voltage, the wind speed air quantity of fan It is likely difficult to meet normal use, although can also play a role and maintain a period of time, controllability is deteriorated, we This voltage threshold is named as：Maintenance voltage.

This maintenance voltage threshold value is arranged to very low 0.9V by this example 3, due to real-time under subnormal voltage operation state The fluctuation of voltage is larger, and for voltage Wave crest and wave trough pressure difference up to more than 0.05V, pressure drop is obvious, but can still meet certain wind Amount, therefore it is 0.8V or so that can even set the maintenance voltage threshold value, this certain voltage is for the drag cup fan It can also still run, due to the general less feature of micro hollow cup internal resistance, although 0.9V or so can also still be run, Air quantity is smaller, and cell output current also very little, and 1.2V or so can be arrived with booster tension even with boost module, But output current has not reached controllable require that.It could be arranged to when cell voltage is less than maintenance voltage, control module is stopped Only work, stop intermittent operational mode, normally closed connected state is remained between battery and motor, motor is in continuous service shape State, while indicator lamp red light Chang Liang, user can may determine that needs change electricity by indicator lamp and non-intermittent operation Chi Liao, even so, still operation at least more than 1 day can be maintained with low-level, the replacing battery sufficient to user when Between, rather than as existing numerous portable air purifiers, run or so three or four hours, say that out of power has no sign just Directly stop.

The cruising time of one batteries has been enough, therefore this example 3 uses the solution of No. 5 batteries of section, This is nearly impossible in brushless Jing Yin motor.No. 5 battery designs are from main body cover 1 by this example 3 and example 2 The solution that outside is mounted directly or changed, as shown in Figure 5 42 be one section No. 5 batteries 52 battery case enclosing cover, this example 3 The battery case enclosing cover is designed as Unscrew, the straightforward procedure shut is reversely rotated again after changing battery, on battery case Installation and the scheme of opening have a lot, do not illustrate one by one herein.

The rotating shaft of hollow-cup motor of the present invention is much smaller relative to brushless quiet fan rotor, is meeting air quantity On the basis of the diameter design of flabellum can be obtained it is smaller, the drag cup fan be installed on as far as possible from nose cup portion closer to position Put, it may also be necessary to which design and installation is in the conduit part, or even at nose cup portion air inlet, if design and installation is in outside main body In shell, design as far as possible at the air outlet of main body.

The example 4 using two No. 7 batteries 53 of section is illustrated in figure 7,2 No. 7 battery designs of section are to be mounted directly by this example 4 In the inner chamber body of main body cover 1, because cruising time long enough, therefore user can be changed opening the casing cover When battery, while filtering material is changed, also easily.

This example 4 will be used using 2 No. 7 battery 3V voltages of section, this example：Two-part powering mode, by control module 33 Voltage stabilizing module output voltage stabilizing output voltage threshold value be arranged to 1.2V, according to actual scene need can also by voltage stabilizing export electricity Pressure threshold value is arranged to broader output voltage, such as 1.0-1.5V.The minimum voltage stabilizing input voltage for setting battery is 1.8V or so, Of course, other minimum voltage stabilizing input voltage threshold values, such as 2.2V or other wider threshold values can also be set according to actual conditions Scope.When cell voltage is higher than the threshold value of minimum voltage stabilizing input voltage, voltage stabilizing output current is exported by Voltage stabilizing module, it is described Fan is worked using periodic running pattern, when cell voltage is less than the threshold value of minimum voltage stabilizing input voltage, with aforementioned exemplary 3 3rd section the same, directly switches to the pattern using continuous service, the red light Chang Liang of indicator lamp window 45, prompts user to change electricity Pond.

Voltage regulation result meeting is exported after 2 No. 5 battery 3V of section are carried out into voltage stabilizing decompression more preferably, due to No. 5 high-quality batteries of a section Quality saves weight of No. 7 batteries equivalent to 1 No. 5 batteries of section in 23.5g or so, a No. 7 battery 11.5g of section or so, substantially 2, Weight is substantially suitable, more stable using No. 7 battery voltage stabilizing outputs of 2 section.But a capacity for saving No. 5 high-quality batteries has 2200- 2400mAH or so, and No. 7 batteries of section typically only have the 2/ of No. 5 batteries of section only less than 800mAH or so, 2 No. 7 batteries of section 3 or so capacity, cruising time can be shorter, therefore respectively have advantage using 2 section 7 and a section 5, can be according to different need Actual design is carried out, such as children's money or female user, No. 5 batteries of section that above-mentioned example 3 is used are changed to a section 7 Number battery, such weight can be lighter, and volume is smaller.Example 4 can also be used 2 No. 7 batteries of section to be changed to 2 sections 5 Number battery, to realize the demand for the moving user for needing overlength continuation of the journey demand or large amount of exercise.

Of course, above-mentioned three kinds of sectional power supply patterns are equally applicable to other rechargeable batteries, three different output voltages Threshold value can be needed according to the scene of product and actual demand is flexibly set, it is not limited to above-mentioned data.

In summary, above by based on the earlier application《Rear-mounted breathing equipment》Designed for agent structure The elaboration of the solution of the rear-mounted respirator with air purifying function in head of batch (-type) air-supply, it is only for conveniently illustrate this hair A kind of energy-saving blowing method of bright described Portable air purifier and the few examples used, it is described to be transported using batch (-type) Capable method and do not represent using the method for hollow-cup motor and be used only for above-mentioned example, portable air of the present invention The energy-saving blowing method of purifier, include including at least main body, fan, battery, the main body outside the main body of foregoing examples Shell, the also agent structure with air-cleaning function including other styles.

Power-economizing method of the present invention using drag cup fan is applied basically for various Portable air purifiers, It is characterized in that：The fan of the power drive system is the drag cup fan using hollow-cup motor.Only need individually using empty Heart cup fan just possesses very efficient subversiveness energy-saving effect.Further, structure of the air cleaning unit positioned at face Part has touch switch, and the power drive system of the air cleaning unit uses periodic running pattern, when people is in air-breathing, Because air-flow caused by air-breathing or negative pressure touch the touch switch so that the fan brings into operation, and stops suction or exhales When touch switch reduction or counter motion, fan it is out of service.

The method of the periodic running of the present invention being controlled using touch switch, it is characterised in that：It is described to exhale The power drive system for inhaling device uses periodic running pattern, and the air cleaning unit has positioned at the structure division of face to be touched Control switch, when people is in air-breathing, due to air-breathing at the spiracle and air inlet caused by air-flow or negative pressure touch touch switch, make Obtain the fan to bring into operation, touch switch reduction or counter motion, fan are out of service when stopping suction or exhaling.

Because can be controlled using control module, the touch switch includes above-mentioned single stationary contact touch switch, more The trigger signal source touch switch such as stationary contact Multistage Control touch switch and pulse signal, swept resistance formula, adjustable capacitance type, The touch switch can be installed on air cleaning unit positioned at any position of the structure division of face according to Design modelling needs Put, also the spiracle of the face structure including air cleaning unit, steam vent and air inlet, the spiracle is to be exhaled at nostril The passage of gas and air-breathing, the air admission hole are close to the inlet channel near mouth and nose positioned at face, and the steam vent is installation The exhaust outlet of air bleeding valve.The touch switch is preferably installed at the spiracle nearest from nostril by the present invention, less preferred installation It is so more sensitive to inspiratory airflow in air inlet position, fan is controlled by inspiratory airflow or intake negative-pressure trigger control module Operation.

It is above-mentioned true it is stated that two kinds of power-economizing methods can be used alone, when will be using the energy-saving square of drag cup fan Method has subversive energy-saving effect beyond imagination when using being combined using periodic running pattern.

Embodiment

Fig. 6 is the exemplary plot of aforementioned exemplary 3, and the example 3 compares that can to embody portable air of the present invention net Disguise the energy-saving blowing method put, will be explained below using Fig. 6 example showns 3 as embodiment.

The present embodiment is still using foregoing earlier application《Rear-mounted breathing equipment》Agent structure, here only just electricity Drive system part is explained.

The present embodiment installs the double diaphragm touch switches 82 of diplopore at nose cup portion spiracle, and the touch switch 82 is Three touch five grades of more stationary contact Multistage Control touch switches, 5 grades of voltage stabilizing output voltages exported respectively may be configured as 1.05V, 1.10V, 1.17V, 1.25V, 1.35V, the present embodiment use the drag cup of 4.5 Ω ends internal resistance 612, can meet from quiet breathing to fortune The discharge quantity of fan of dynamic state, it can meet that assist type air-supply of the present invention requires completely.

The control module has voltage compensating function, and arranges value model is matched when respiratory rate is in touch switch gear Lifting is compensated when enclosing interior to corresponding gear voltage stabilizing output voltage or is reduced, it is 0.06V left that the present embodiment, which sets offset voltage, It is right.Because everyone lung capacity is different with respiratory rate, the present embodiment is especially provided with and calculated according to respiratory rate, carries automatically Every grade of voltage stabilizing output voltage values are risen or reduce, when respiratory rate is less than 13 beats/min, and the gear of touch switch 82 connects Continuous 5 times in two, third gear when, automatic lifting one, two, the voltage 0.06V of each shelves of third gear, when respiratory rate be 18 beats/min with When upper, and when continuous 5 times of the gear of touch switch 82 is in one, two grade, the voltage 0.06V of each shelves was reduced automatically.
