Summary of the invention
The present invention seeks to disclose and a kind ofly accelerate the air-dry method of clothes on clothes hanger, and the electric weight of its consumption is very low.
Method of the present invention is, adopt a mechanical device, by mechanical device, clothes hanger being produced swings, the clothes that drive hangs on clothes hanger produces swing, cause the air of garment surface to produce relatively mobile, constantly take away the hydrone of fleeing from from clothes, accelerate the evaporation of clothes water, thereby it is air-dry to accelerate clothes.
Design principle of the present invention is: by analysis, the in the situation that of same temperature and humidity, wet clothes are easily dry when having wind, be due to the hydrone on clothes constantly flee from clothes and constantly by wind also mobile air take away, make constantly evaporation and becoming dry of moisture.And while there is no wind, hydrone is fled from after clothes owing to not having Air Flow to take away, so assemble, be attached to garment surface, having hindered other hydrones continues evaporation, thus it is air-dry that clothes is not easy.Obviously, if adopt fan to clothes blowing help air-dryly, be that effectively this is also those skilled in the art's methods that thinking may be expected routinely.But inventor feels, in order effectively to blow to all clothes of whole clothes hanger, fan needs tens watts of above power, although be not very large, needs the long period, so power consumption is in fact also not little through calculating owing to completing whole air drying process.
So, the present invention is thinking anomaly, and adopt simply and cleverly method of another kind, adopt a mechanical device, the clothes hanger generation that hangs with clothes is swung, (described swinging be swinging in the direction perpendicular to cross bar, plane of oscillation is vertical with cross bar), drive makes the relative air of clothes produce swing, cause the air of garment surface to produce relatively mobile, constantly take away the hydrone of fleeing from from clothes, accelerate the evaporation of clothes water, realize and accelerate the air-dry effect of clothes.This method also brings special technique effect to be: because clothes hanger is skyborne by the tightrope suspension at cross bar two ends, the weight of clothes is all born by tightrope, so only need very little power and energy just can make whole clothes hanger and clothes above thereof produce and swing at left and right directions; Because the mobile of absolute position occurs whole clothes hanger, do not change, its action that swings is actually a kind of oscillating movement of ripple, so required energy is very little, and after once external force swings it, even if external force loses clothes hanger, can also oneself continue within a certain period of time to maintain swing, (be also oscillatory occurences, due to air drag, this vibration is convergent oscillation, until External Force Acting next time).In other words, the oscillatory occurences of the power utilization clothes hanger of mechanical device of the present invention has played the ingenious effect that art is good for strength, the present invention is had with very little energy just can make all clothes produce swing, reach and accelerate the air-dry good effect of all clothes, this is also creative place of the present invention.In experiment, hang with the clothes hanger of 10 wet clothes, 1 meter of left and right of the unsettled length of tightrope, together with cross bar gross weight more than 10 kilograms, promote whole clothes hanger and produce the left and right swinging distance of 10 centimetres altogether, only need the power of about 0.5 kilogram, (in cross bar side, vertically act on cross bar), and can be exerting oneself of intermittent, be equivalent to push away gently in the horizontal direction with finger, then finger can leave, and at this moment all clothes on clothes hanger just swing together, and can also oneself maintain the sustained oscillation (oscillatory occurences) of a period of time, extremely save energy.Because the cycle that clothes hanger is swung is long, that is to say that external force can be with the slowly effect of less power, and the effect of external force can be intermittent, so on average get off its operating power and total power consumption all very little.
Innovation of the present invention is to note and utilize oscillatory occurences and this ingenious mode that art is good for strength of clothes hanger, by clothes hanger is swung, with very little power and power consumption, just can make all clothes of whole clothes hanger accelerate air-dry.And for how to drive clothes hanger to swing by mechanical device, can adopt various structures and the technology of mechanical field to realize, and this can have various ways, and as example, the present invention is following several technology openly.
1, described mechanical device adopts a pulling device, and pulling device comprises power set and tractive end, and tractive end produces the tractive action of straight line under the effect of power set; Pulling device is fixedly mounted on a side of clothes hanger cross bar, and (left side or right side, obviously best installation site is to be in highly equal position with clothes hanger cross bar), adopts stay cord that tractive end is connected to cross bar; The tractive end of pulling device pulls clothes hanger cross bar by stay cord, cross bar is produced and swing, thereby drive whole clothes hanger and clothes to swing.The length of stay cord can be adjusted according to the height and distance of clothes hanger cross bar, can also be added with elastic force apparatus (as one section of rubber band) and play cushioning effect in the middle of one end of stay cord or stay cord.This mechanical device that produces straight line tractive action by power is the ordinary skill of mechanical field, can adopt various structures to realize.A kind of mode such as pulling device: employing motor is power set, electric machine rotation is converted into the mode moving back and forth and produces tractive action.Pulling device includes the tractive end of motor, gear, moving runner and connection of rotating wheel; Take motor as power, by reducing gear, drive moving runner to rotate, (rotating the time about 1 of one week to several seconds), drives tractive end to produce reciprocal tractive action back and forth by the fixing point on moving runner (be generally located at the side of moving runner and approach on the position of circumference) when moving runner rotates.This mode is fairly simple, and its advantage is because hunting period is longer, so can adopt micro machine that power is very little just can realize tractive by gear, moves, and the operating power of motor is probably several watts of left and right.Motor can be continuous operation, and at this moment moving runner rotates continuously, by the continuous tractive clothes hanger of tractive end, make the amplitude of fluctuation of clothes hanger larger all the time, but power consumption is also continuous, still larger.As improvement, motor can be also that the energising of intermittent is rotated, drive moving runner to rotate a circle, tractive end is produced after a tractive action, when the near clothes hanger of tractive termination (at this moment stay cord, in relaxation state, does not produce traction action to clothes hanger) away from clothes hanger, stop operating, clothes hanger is because oscillatory occurences continues to maintain swing, but amplitude of fluctuation is more and more less, produces next tractive action until motor rotates next time.Pulling device just produces a tractive action every certain gap periods like this, and (gap periods about several seconds to tens seconds, about 1 to several seconds working times), mean power will be less, more power saving.But the job control to motor relatively bothers, and moving runner swing with cross bar when rotating is very difficult synchronous, and asynchronous meeting checks and balance, and waste energy, has affected power savings.
So pulling device can adopt another kind of better mode: produces by electromagnet the tractive that mode that electromagnetism moves produces pulsating and move.Adopt electromagnet to be used as power set, pulling device comprises electromagnet and tractive end, and electromagnet comprises coil and iron core (or armature), and iron core (or armature) connects tractive end, coil electricity produces magnetic fields and produces action in iron core, and iron core moves by tractive end tractive clothes hanger.(can certainly directly adopt a straight moving electromagnet of drawing in, its iron core is connected to tractive end).If the displacement of iron core tractive can not adopt lever principle to increase tractive displacement completely.This mode is larger at the operating power of coil electricity moment, but because once (being equivalent to point to push away leave after clothes hanger) generation, the of short duration tractive of clothes hanger can oneself maintain lasting swing (oscillatory occurences) in a period of time (tens seconds to tens seconds) after swinging, so solenoid can interval energising work, by circuit, control at set intervals (tens seconds to tens seconds adjustable) just to the very short electric pulse of pulse width of solenoid energising (pulse width approximately more than 0. seconds adjustable), make iron core drive tractive end to produce the tractive action of intermittent.Also be the oscillatory occurences that pulling device utilizes clothes hanger, each certain hour is the tractive action of a pulsating of generation of intermittent, and because the conduction time (being pulse width) of solenoid can be very little, so the power consumption of on average getting off is very low, about more than 0. watts of left and right.
Although the above-mentioned technology principle that pulls clothes hanger produce to swing by pulling device is simple, need to be at clothes hanger one side fixed installation pulling device while using, then connect clothes hanger by stay cord, not only bothered but also occupation of land side relatively.So, further improving, the present invention also discloses another two kinds of technology more cleverly.
2, described mechanical device is a pendulous device, pendulous device is hung on the cross bar of clothes hanger, drives cross bar to produce swing when the fork of pendulous device swings by reaction force, thereby drive whole clothes hanger and clothes to produce, swings.Pendulous device includes installed part, fork and power set, installed part is for being arranged on clothes hanger cross bar by pendulous device, fork is suspended on pendulous device can swing (being that plane of oscillation is vertical with cross bar), and power set transferring power, to fork, promotes fork and swings.Power set generally adopt electromagnetic mechanism as power (operation principle of similar electronic pendulum clock), also can adopt if desired the mode (operation principle of similar mechanical pendulum clock) of mechanical spiral power spring storaging energy, but that the working time is difficult to accomplish is very long.These are common technique of clock and watch technical field, but be applied on clothes hanger, its meaning is: by fork, swing to drive clothes hanger to swing, acceleration clothes is air-dry, and because fork swings and clothes hanger swing is all to swing in a kind of oscillatory regime, consumes energy very little, about more than 0. watts, and pendulous device is directly hung on clothes hanger cross bar and gets final product work while needing, space-saving, use also more convenient.
3, described mechanical device is an impulsion device, impulsion device is arranged on the cross bar of clothes hanger, impulsion device includes power set and motion block, motion block produces impulsion action at left and right directions (be also horizontal direction or close to horizontal direction) under power set effect, by reaction force, promote cross bar generation and swing, thereby drive clothes hanger and clothes to produce, swing.The oscillatory occurences of utilizing clothes hanger to swing, the impulsion action of motion block can be intermittent, motion block just produces an impulsion action at regular intervals, is equivalent to use at intervals finger push one sheer pole, then unclamps the clothes hanger oneself of leaving and swings.Impulsion device includes installed part, power set and motion block, and installed part is for being arranged on clothes hanger cross bar by impulsion device, and motion block has certain quality, and under the effect of power set, motion block produces impulsion action at left and right directions.Power set can adopt solenoid to coordinate iron core to produce electromagnetic force, make motion block produce impulsion action.Iron core is connecting motion block, or iron core is integrated with motion block, or iron core itself is exactly motion block.Power supply by control circuit intermittent (gap periods about several seconds to tens seconds adjustable) coil is carried out to pulse electrifying (electrical pulse width be generally more than 0. seconds adjustable), during coil electricity, produce magnetic fields in iron core, make motion block produce an impulsion action, by reaction, the cross bar of clothes hanger is produced and swing.The meaning of this technology is: equally when needed impulsion device directly hung on clothes hanger cross bar and gets final product work, and the pendulum significantly swinging that does not need to expose, take up space less, use more convenient, and due to intermittent energising work, power consumption is very little too, it is also about more than 0. watts.

the specific embodimentbelow with reference to the accompanying drawings, embodiments of the invention are described.
Fig. 1 is the operation principle schematic diagram of common clothes hanger.Clothes hanger includes cross bar and tightrope, and the two ends of cross bar 2 hang on ceiling by tightrope 1, and cross bar 2 is suspended in the air.Some clothes hanger of market is also with regulating by adjusting tightrope 1 length the elevating mechanism of clothes hanger height.Cross bar 2 can hang with clothes hanger 3 above, and on clothes hanger 3, surface cover has wet clothes.The common conventional a kind of clothing mode of drying in the air of Zhe Yeshi family.
The present invention adopts a mechanical device, by mechanical action, the clothes hanger generation that hangs with clothes is swung, (being that plane of oscillation is vertical with cross bar), thereby make clothes produce and move relative to air, cause the air of garment surface to produce relatively mobile, constantly take away the hydrone of fleeing from from clothes, accelerate the evaporation of clothes water, thereby it is air-dry to accelerate clothes.
Mechanical action for how by mechanical device swings clothes hanger, can adopt various structures and the technology of mechanical field to realize, as example, the present invention discloses several technology in " summary of the invention " part, is below some specific embodiment of these technology.
For mechanical device, adopt a pulling device, the tractive of the tractive end by pulling device moves tractive clothes hanger to produce the technology swinging.The present invention discloses two kinds of working methods to " pulling device ".Be a mode for pulling device " adopt electric machine rotation be converted into tractive end move back and forth to produce tractive action ", this is the simple conventional technology of mechanical field.Power set include motor, gear and moving runner; Moving runner connects tractive end; Tractive end connects stay cord.Take motor as power, by reducing gear, drive a moving runner to rotate, (rotating the time about 1 of one week to several seconds), as Fig. 3, thereby during moving runner 20 rotation, by the fixing point on moving runner, driving 29 motions of tractive end to drive stay cords 26 to produce reciprocal tractive back and forth moves, (in Fig. 3, in fact tractive end that is to say the fixing point on moving runner, generally be located at the side of moving runner and approach on the position of circumference, notice that stay cord is not twisted on moving runner, but all the time in a side of moving runner), moving runner rotates the moving tractive end of an astragal and produces once reciprocal tractive action, by stay cord 26, going tractive clothes hanger to produce again swings.This mode is fairly simple, can adopt micro machine that power is very little just can realize tractive by gear and move, and the operating power of motor is probably several watts of left and right.Motor can be continuous operation, and at this moment moving runner rotates continuously, by the continuous tractive clothes hanger of tractive end, make the amplitude of fluctuation of clothes hanger larger all the time, but power consumption is also continuous.Motor can be also that the energising of intermittent is rotated, drive moving runner to rotate a circle, tractive end is produced away from clothes hanger (being that Fig. 3 tractive end 29 forwards rightmost place to) after a tractive action, at tractive end, revert to while approaching clothes hanger and stop operating, (be that Fig. 3 tractive end 29 forwards Far Left place to, at this moment stay cord 26 is in relaxation state, clothes hanger is not produced to traction action), clothes hanger is because oscillatory occurences continues to swing, but amplitude of fluctuation is more and more less, until rotating next time, motor produces next tractive action, motor carries out interval work with certain gap periods like this, (about tens seconds to tens seconds of gap periods, about 1 to several seconds working times), more power saving.
And for the mode of pulling device " mode that adopts electromagnet to produce electromagnetism action produces the tractive action of pulsating ", power set adopt electromagnet, pulling device comprises electromagnet and tractive end, electromagnet comprises coil and iron core (or armature), iron core (or armature) connects tractive end, coil electricity produces magnetic fields and produces action in iron core, and iron core moves by tractive end tractive clothes hanger.Fig. 4 is the structural representation of pulling device (being the pulling device 4 in Fig. 3).Shell 21 the insides are provided with coil 22, in the middle of coil 22, it is hole 23, the iron core 24 of being made by soft magnetic material can be inserted on hole 23, iron core front end (left end) is connected with tractive end 25, and with spring 27, (spring 27 in Fig. 4 is stage clip, also can change extension spring into and realize with mutually applicable structure).Under the effect of spring 27, iron core 24 major parts are in the outside of coil 22 at ordinary times.While carrying out pulse electrifying under the control of coil 22 at circuit, coil 22 generates an electromagnetic field, and attracts iron core 24, makes iron core overcome the elastic force of spring and moves right hand-hole 23 the insides of going forward side by side, thereby driving tractive end 25 to produce the tractive action of a pulsating to the right.When the electric pulse of coil finishes, electromagnetic field loses, and iron core 24 again stretches out reset under spring action, waits for action next time.Power supply can adopt battery or be provided by power supply adaptor, (gap periods was at several seconds to tens seconds the cycle at regular intervals by control circuit for power supply, can be adjusted by control circuit) an electric pulse (pulse width approximately more than 0. seconds of output, adjustable) give coil, these are all electronic applications common technologies.
The operation principle of pulling device is as Fig. 2.During use, pulling device 4 is fixedly installed to a side (left side or the right side of clothes hanger, obviously best installation site is with the cross bar 2 of clothes hanger, to be in the position of sustained height), as be arranged on wall 28, adopting stay cord 26 is the tractive end 25 in Fig. 4 by tractive end 25(, also be the tractive end 29 in Fig. 3) be connected to the cross bar 2 of clothes hanger, obviously preferably stay cord 26 is vertical with cross bar 2 or close to vertical for connection angle.When pulling device produces a tractive action, tractive end pulls the cross bar 2 of a clothes hanger by stay cord 26, whole clothes hanger and clothes are produced to swing, and oneself maintain within a certain period of time swing (oscillatory occurences), swinging can be more and more less, until pulling device produces next tractive action.Obviously, when gap periods is larger power consumption less, but the average amplitude that clothes hanger swings is less, otherwise contrary.The length of stay cord 26 can be adjusted according to the height and distance of clothes hanger, can also be added with elastic force apparatus (as one section of rubber band) and play cushioning effect in the middle of one end of stay cord or stay cord.
Described mechanical device can be also a pendulous device, and pendulous device includes installed part, fork and power set.Fig. 5 is the structural representation that hangs over a kind of pendulous device on clothes hanger cross bar 2.Pendulous device includes installed part 31, shell 32 and fork 35.Installed part 31 is for being arranged on cross bar 2 by whole pendulous device head, and other parts hang downwards, and mounting means can be to adopt elastic structure to clamp, adopt the variety of ways such as screw locking, even adopts and is directly hooked on cross bar.Pendulous device can be fixed on any position of cross bar, but it is best to be obviously arranged on the centre position effect of cross bar, and the two ends that are arranged on cross bar are more convenient.Shell 32 the insides are provided with circuit part 33, comprise supply unit and control circuit board.Terminal position at outer casing underpart is provided with solenoid 34, and is provided with magnetic field detection element (as Hall element).Fork 35 is suspended on the shell of pendulous device by being flexibly connected 39, being flexibly connected 39 can be the structure of an axle and ring, such as bearing, or a hook structure, fork can be suspended on an axle above shell and swing, (being similar to pendulum).Fork 35 has certain mass to produce enough reaction forces, can adopt aluminium to make, and also can be added with endways the weight 36 that increases quality.On fork, on the position being highly equivalent to below solenoid 34, by fixed mechanism 37, the magnet 38 with solenoid 34 cooperatings is installed, the general permanent magnet that adopts of magnet 38, also can adopt induced electricity magnet certainly.The pendulous device of Fig. 5 adopts calutron to produce electromagnetic force and is used as the power set that drive fork to swing, the operation principle of similar electronic pendulum clock, also can adopt if desired the mode of mechanical spiral power spring storaging energy to be used as power set, the operation principle of similar mechanical pendulum clock, but that the working time is difficult to accomplish is very long.
Operation principle when pendulous device swings is as Fig. 6.Fork 35 is suspended on and is flexibly connected on 39, similar pendulum equally swings, when swinging, fork 35 passes through minimum point, while being also the below of the firm solenoid 34 through shell lower end of permanent magnet 38 on fork, magnetic field detection element testing is to the magnetic field of permanent magnet 38, obtain a position signalling, (also can adopt travel switch or optoelectronic switch to detect), circuit arrangement is according to this input signal, export an electric pulse to coil 34, make coil 34 produce a magnetic field force (repulsion of magnetic field same polarity) that repels permanent magnet 38, thereby promote permanent magnet 38 and also promote fork 35 continuation swings.Short pulse of coil electricity, just produces direct action power to fork, thereby fork is ceaselessly swung.Because pendulous device is arranged on clothes hanger cross bar, swinging of fork drives clothes hanger also to occur swinging by reaction force.Obviously, strengthen quality and the length of fork 35, can strengthen the amplitude of fluctuation of clothes hanger, but power consumption increasing is contrary on the contrary.General, fork (together with weight) quality is between several hectograms are to several kilograms, and length is chosen between tens centimetres at tens centimetres.Solenoid of the every swing of this mode fork need to be switched on once, so the energization interval cycle is shorter, but because fork is in oscillatory regime (pendular movement), each magnetic force that only need to be very little, so the operating power of solenoid can be very little, whole power consumption is also very little, below 1 watt.And pendulous device is directly installed to hang on clothes hanger cross bar while needing and get final product work, space-saving, use easily.
Pendulous device also can adopt the device as Fig. 9 and Figure 10, and its operation principle separately has narration in the back, and this kind of its solenoid of pendulous device can carry out energising work with longer gap periods, is conducive to more power saving.Pendulous device can also adopt other modes.Such as, adopt motor as power set, electric machine rotation drives fork around being flexibly connected head rotation by transmission mechanism, and fork lower end is lifted on slowly; When fork arrives a certain position, transmission mechanism discharges fork, allows fork lower end hurtle down because of gravity, forms one time wobbling action, and drives the generation of clothes hanger cross bar to swing by reaction force.
Described mechanical device can be also an impulsion device.Impulsion device includes installed part, power set and motion block, and installed part is for installing impulsion device to hang over clothes hanger cross bar, and mounting means and installation site are similar to pendulous device recited above.Motion block has certain quality, under the effect of power set, produces impulsion action at intervals at the left and right directions direction of cross bar (perpendicular to), thereby drives clothes hanger to swing.Power set generally adopt solenoid to coordinate iron core to produce electromagnetic force, make motion block produce impulsion action.Fig. 7 is the structural representation that hangs over a kind of device of getting excited on clothes hanger cross bar.Installed part 41 fixedly hangs over impulsion device on clothes hanger cross bar 2, and shell 42 the insides are with circuit arrangement 43, (comprising power supply and control circuit).By solenoid 44, coordinate iron cores 46 to be used as power set, when solenoid 44 energisings produce magnetic field, iron core 46 is attracted, thus in solenoid interstitial hole 45 the insides to left movement.Motion block 47 has certain quality, and (together with the gross mass of iron core between several hectograms are to several kilograms) can produce certain reaction force to cross bar, and iron core 46 is connecting motion block 47, or iron core is integrated with motion block, or iron core itself is exactly motion block.Power supply is by control circuit intermittent (gap periods about several seconds to tens seconds, adjustable) solenoid 44 is carried out to pulse electrifying, (electrical pulse width be generally more than 0. seconds adjustable), during solenoid 44 energising, produce magnetic field, iron core 46 is attracted to left movement, drive motion block 47 to produce an impulsion action left, as Fig. 8.The displacement (stroke) of motion block impulsion is determined according to motion block quality, is generally several centimetres, and after energising finishes, magnetic field disappears, in effect lower core 46 and motion block 47 recoveries of spring 48.And this impulsion action that motion block produces, can cross bar 2 be produced by reaction force and swing, thereby drive whole clothes hanger and clothes to swing, and oneself maintain within a certain period of time swing (oscillatory occurences), swinging can be more and more less, until motion block produces next impulsion action.(be equivalent to finger, promote fast a sheer pole at intervals, then unclamp the clothes hanger oneself of leaving and swing).Obviously, when gap periods is larger power consumption less, but the average amplitude that clothes hanger swings is less, otherwise contrary.The advantage of this technology is: just impulsion device is directly hung on clothes hanger cross bar and gets final product work equally when needed, and the pendulum significantly swinging that does not need to expose, take up space less, use more convenient, and due to the work of intermittent pulse electrifying, power consumption is also very little, and average power is below more than 0. watts.So power supply can adopt battery or rechargeable battery, without connecting alternating current, use more convenient.
Fig. 9 is the structural representation that hangs over the another kind impulsion device on clothes hanger cross bar.Installed part 51 fixedly hangs over impulsion device on clothes hanger cross bar 2, and shell 52 the insides are with circuit arrangement 53, (comprising power supply and control circuit).By solenoid 54, coordinate iron core 46 to be used as power set.Iron core 56 is with spring 58.Iron core 56 is connecting motion block 57.Motion block 57 is by connecting rod 60 and be flexibly connected 59 and be movably connected and hang on shell 52.Motion block 57 has certain quality, (together with the gross mass of connecting rod between several hectograms are to several kilograms).Power supply by control circuit intermittent (gap periods about several seconds to tens seconds adjustable) solenoid 54 is carried out to pulse electrifying, (electrical pulse width be generally more than 0. seconds adjustable), when solenoid 54 energisings produce magnetic field, iron core 56 is attracted, overcome the effect of spring 58, in solenoid interstitial hole 55 the insides, to left movement, and by connecting rod 60, drive motion blocks 57 to produce an impulsion left to move, (reality is also a swing left), as Figure 10.Displacement when connecting rod 60 is got excited for increase motion block 57 by leverage.After energising finishes, magnetic field disappears, in effect lower core 56 and motion block 57 recoveries of spring 58.And this impulsion (swing) action that motion block 57 produces, can cross bar 2 be produced by reaction swings, thereby drive whole clothes hanger and clothes thereof to swing, and oneself maintain within a certain period of time swing (oscillatory occurences), swinging can be more and more less, until motion block produces next impulsion action.(be equivalent to finger, promote fast a sheer pole at intervals, then unclamp the clothes hanger oneself of leaving and swing).The setting of gap periods of the impulsion device of Fig. 9 and the advantage of power saving thereof are the same with Fig. 7 device of getting excited, but also can make by the effect of bar thick stick the displacement in motion block when impulsion larger, thereby can adopt the motion block of less quality, and be conducive to improve the amplitude of fluctuation of clothes hanger.Its motion block 57 of the impulsion device of Fig. 9 is also a kind of dancing together with the impulsion action reality of connecting rod 60, and drive cross bar to produce swing by reaction force, so be also similar to the work of the pendulous device of Fig. 5, and its solenoid can carry out energising work with longer gap periods, be conducive to more power saving.
