Description

Humidifier

Technical field

The invention belongs to technical field of electric appliances, relate to a kind of humidifier.

Background technology

Relevant studies show that: over nearly 30 years, along with the year by year rising of Global Temperature, air humidity is descending year by year.The incidence of disease of the diseases such as influenza, bronchial astehma, allergic dermatitis, pulmonary emphysema improved more than 30% before 30 years; The occurred frequently of these diseases is because the immunity degradation of human body causes, its reason is that people live in the lower environment of humidity for a long time, immunity of organisms descends, people are in a kind of " sub-health state ", the people of sub-health state is vulnerable than the person of health, be vulnerable to virus and the infringement of bacterium, and the low environment of humidity is conducive to breeding and the propagation of germ, germ wreaks havoc more.But reach in 55% in air humidity, germ is difficult to propagate, and the air humidity that therefore is of value to health should remain between the 45%-55%.And this standard that reaches is seldom arranged in the family of modern metropolitan cities, for above situation, people just design the equipment that can improve air humidity.This equipment is exactly humidifier, and existing humidifier has ultrasonic type, direct-evaporation-type, electrothermal, centrifugal, combined type etc., and the most frequently used is exactly the humidifier of ultrasonic type.The operation principle of ultrasonic type: be the principle that adopts the ultrasonic wave higher-order of oscillation, making water fogging is the ultramicron of 1-5 micron, by aerophor water smoke is diffused in the air, reaches the purpose of even humidifying air.The ultrasonic humidifier critical piece comprise water tank, ultrasonic water smoke generate mechanism, for increasing the wind pushing mechanism of water smoke diffusion velocity, ultrasonic water smoke is generated water smoke that mechanism produces converge and be dispersed into airborne water smoke and distribute pipe.

There are some problems in existing humidifier: the one, and water tank is to be placed on the top that ultrasonic water smoke generates mechanism, and namely water tank is arranged on the base top, and the lower limb of water tank is provided with a circle baffle plate, and the baffle plate spiral-lock is placed in water tank on the base outside the tank on base top.The water smoke that ultrasonic water smoke generates the ultrasonator vibration generation that arranges in the mechanism fills the air in tank, although most of distributing from water smoke is dispersed in the air the pipe, but can be from humidifier slit everywhere, for example from the connecting sewing of tank and baffle plate, shed, and since the baffle plate spiral-lock outside tank, the water that condenses between baffle plate and tank downstream groove outer wall flows down, be dropped in around the humidifier, easily drench article around the humidifier, and the water of drippage also can flow over after gathering, cause inconvenience to the user.

The 2nd, it is integrative-structure that the water tank of existing humidifier and water smoke distribute pipe, the two can not separate and water smoke distributes the center that pipe is positioned at water tank, such structure makes the manufacturing process of water tank comparatively complicated, and the reason owing to manufacturing process, water tank to be divided into two parts, upper part is that water tank main body and water smoke distribute pipe, lower part is tank floor, and then amalgamation is made in split separately, again by ultra-sonic welded together.This manufacturing process operation is many, comparatively complicated on the one hand, ultra-sonic welded is prone to the imprecise quality problems of welding on the other hand, and the water tank of ultra-sonic welded requires by the air pressure hydraulic pressure test, the existence of combination of ultrasound line so that the bearing capacity of water tank be affected.In addition because water tank need to be pulled down from humidifier and adds water, and the probability that is therefore collided with, drops is larger, water tank collided with, fall that to fall behind in ultrasonic closing line place easy to crack, the radiator leak situation occurs.

The 3rd, the humidifier of selling on the market has a very formidable shortcoming, be exactly after a period of time left by humidifier, particularly when adjusting product mist amount is larger, there is the larger water mist particle of some particle diameters in the water smoke of humidifier ejection, airborne dust or particle easily gather them, accumulate to a certain degree, will fall to desktop, the body surfaces such as ground, can produce the same moisture film of one deck " dew " at body surface for a long time, we are referred to as " seeping phenomenon ", work long hours at humidifier, can be with desk around the humidifier when serious, drench on floors etc., also and drench its periphery other article, have influence on humidifier result of use in the family, and can drench humidifier, water is penetrated into humidifier inside, cause Electrical Safety hidden danger, cause the humidifier fault, even can affect the humidifier life-span.

The 4th, the water smoke of ultrasonic humidifier is the oscillator plate generation high frequency oscillation by ultrasonator, is the water smoke of 1-5 micron ultramicron with aquation, by wind pushing mechanism water smoke is distributed the pipe from water smoke to blow out, and is diffused in the air, reaches the purpose of even humidification.But oscillator plate is when producing high frequency oscillation owing to be operated under the different parameters, water may be evoked one as fountain water column or agitated a lot of sprays, water column can reach certain height in humidifier.In order to make oscillator plate performance maximum efficiency, oscillator plate has one 7 ° inclined installation angle, so the water column that evokes or spray fall after rise after also can tilting to rise towards 7 ° direction, water column or spray directly freely fall back to the water surface, and the water that can produce than loud noise rings.And condensate water in distributing pipe, water smoke is arranged, the condensate water drippage also can produce noise, in addition, the blower fan that adopts also has larger noise, above-mentioned sound stack has just caused humidifier to have larger noise, can affect like this user's use, particularly at night, people's rest has been arrived in the humidifier noise effect.

The 5th, in the existing humidifier, water tank is arranged on ultrasonic water smoke and generates the mechanism top, and the bottom surface of water tank arranges an Inlet and outlet water mouth of pipe, be used for adding water in water tank, and the water in the water tank flows out to through the Inlet and outlet water mouth of pipe from water tank and carries out ultrasonic atomizatio the tank under Action of Gravity Field.Because the Inlet and outlet water mouth of pipe is arranged on below of water tank, add water or maintenance during tank mentioning water tank, when mentioning water tank, the water in the water tank can spill from the Inlet and outlet water mouth of pipe, exceed the tank capacity and also can spill everywhere if drain to water in the tank, affect the user and normally use.In addition, because the Inlet and outlet water mouth of pipe is arranged on the water tank bottom surface, after the Inlet and outlet water mouth of pipe is opened, do not stop in tank, to leak, can overflow after tank water is full, the overflow mechanism minimizing need to be set overflow.

The 6th, because oscillator plate produces high frequency oscillation in the ultrasonic humidifier in water, the concussion that evokes water produces water smoke, when oscillator plate in anhydrous or situation that the water yield is very few, can occur " dry combustion method ", cause oscillator plate to damage, so humidifier all needs to arrange anti-dry burning device, existing anti-dry burning device is arranged in the tank, water level in the tank is controlled, and then controlling organization control humidifier does not start when water level in the tank reaches or be higher than default oscillator plate working water bit line.But in some cases, for example: although the water level in the tank does not arrive the preset water level line, do not have water in the water tank, when needing feed-tank to pour water, after mentioning water tank, the uncontrollable humidifier of existing anti-dry burning device is out of service, and oscillator plate is worked always, and the water smoke of generation will arbitrarily fill the air, and oscillator plate produces agitates water column or spray can spill humidifier, article around drenching also can drench humidifier, cause the potential safety hazard of electricity consumption.In addition, existing anti-dry burning device exists potential safety hazard, when not having water tank or water tank not to be put into, and the product misoperation; Water in the product tank can " be dryouied " by oscillator plate, still in work, may make the too early damage of product during the product lack of water.

The locating part 711 of restriction magnetic float 712 motions can have various structures: wherein a kind of is the position-limiting tube that vertically arranges, position-limiting tube does not affect the magnetic force of magnetic float 712, the upper end of described position-limiting tube is fixed on water tank 1 bottom surface or at anti-leakage cover 5 inner top surfaces, the lower end of position-limiting tube is provided with the back-up ring that prevents that magnetic float 712 from deviating from, and described magnetic float 712 is placed in the position-limiting tube and with the water surface and fluctuated.

Another kind of mode is: described locating part 711 is limited post, described limited post upper end is fixed on water tank 1 bottom surface or is provided with the back-up ring 711a that prevents that magnetic float 712 from deviating from anti-leakage cover 5 inner top surfaces, lower end, fluctuates outside the described magnetic float 712 suit limited posts and along the limited post more than the back-up ring 711a.Limited post is cylinder or cylindroid, leaves the gap between magnetic float 712 and the limited post, so that magnetic float 712 moves up and down with the water surface, is not subject to the impact of limited post.Present embodiment just adopts this mode.

The can 721 of magnetic switch assembly 72 is the cylindrical shell of top seal, its vertically sealing fixedly on tank 31 inner bottom surfaces, described tongue tube 722 is arranged in the can 721, can 721 sealings, avoid the interior water of tank to enter and cause tongue tube 722 to damage, satisfy the position of described tongue tube 722: when the tank 31 interior waters surface departed from default humidifier working water bit line, tongue tube 722 disconnected, and humidifier quits work.Cause the deviation distance of tongue tube 722 disconnections by magnetic force and the tongue tube 722 closed required magnetic force decisions of magnetic float 712, therefore, can adopt the different deviation distances that require for different humidifiers.

As shown in Figure 1, 2, 3, described water smoke distributes pipe 2 sealings and is fixed on the anti-leakage cover 5 and water smoke distributes the corresponding UNICOM of through hole that offers on pipe 2 inner chambers and the anti-leakage cover 5; Distribute being connected between pipe 2 and the anti-leakage cover 5 in order to strengthen water smoke, prevent from leaking between them water smoke, then to distribute pipe 2 be one-time formed integrative-structure with anti-leakage cover 5 to preferred described water smoke.Water smoke described in the present invention distributes pipe and 2 independently is arranged on water tank 1 one sides, and namely to distribute and manage 2 are each independently structures for water tank 1 and water smoke, so the shape of the two, position each other do not do restriction, can carry out layout according to the humidifier appearance design.But for the overall volume that reduces humidifier and add as far as possible large water tank 1 volume, water tank 1 and water smoke distribute retention gap no longer between the pipe 2, namely such as present embodiment, the outside wall surface that described water tank 1 outside wall surface and water smoke distribute pipe 2 adjacency fits together and makes the two become as a whole, a kind of mode of fitting is at vertically indent formation of water tank 1 sidewall groove, plug-in mounting water smoke distributes pipe 2 in the groove, the another kind of mode of fitting be water tank 1 outside wall surface and water smoke to distribute the outside wall surface of managing 2 adjacency be plane or cambered surface all, the two fits together.

As shown in Figure 1, described water smoke distributes pipe 2 tube cavity body and is column, can be cylindric, prism-shaped, oval column etc.Water smoke distributes in the pipe 2 and is provided with fog-proof plate 21, and the effect of fog-proof plate 21 is water mist particles that " shielding " falls greater particle size in the water smoke.Running into fog-proof plate 21 during the water mist particle of particle diameter rises in the water smoke assembles at fog-proof plate 21 easily, and the less water mist particle of particle diameter is difficult for assembling, just distribute the pipe 2 from water smoke and be blown out in the air, it is just very tiny to be dispersed into so airborne water smoke, gasifies easily and is difficult for cohesion and drops to body surface and form water membrane.The quantity that described fog-proof plate 21 arranges can be one, and fog-proof plate 21 also can arrange at least two in the interval, and adjacent fog-proof plate 21 is crisscross arranged, and distributes the water smoke passage of pipe 2 interior formation winding complications at water smoke.The set-up mode of fog-proof plate 21 has multiple, wherein a kind ofly be: described fog-proof plate 21 distributes pipe 2 inwalls by water smoke and extends to the center, adjacent fog-proof plate 21 is separately positioned on the relative wall also interlaced, be that fog-proof plate 21 extends beyond the axis, so that adjacent fog-proof plate 21 axially seen overlapping, so just water smoke distribute the pipe 2 interior formation winding complications the water smoke passage.Just run into fog-proof plate 21 in the water smoke streamlined flow process, the water mist particle that the part particle diameter is large is gathered on the fog-proof plate 21, and all the other water smokes change flow directions continue to flow, until run into next fog-proof plate 21, the water mist particle that particle diameter in the water smoke is large again is blocked " shielding " and falls, and " shielding " repeatedly is so that the water mist particle that particle diameter is larger in the water smoke greatly reduces, and the water mist particle that is blown is tiny, in air, be difficult for cohesion, also with regard to the corresponding ponding that has reduced at body surface.Fog-proof plate 21 distributes pipe 2 interior horizontally sets at water smoke, horizontally set can be the horizontal cross setting, also can be to be obliquely installed, for smooth and easy the shedding of water smoke energy, avoiding too much tackling water smoke causes humidifier to produce the less problem of mist amount, preferred each fog-proof plate 21 of present embodiment distributes the setting that is inclined upwardly of pipe 2 inwalls from water smoke, described fog-proof plate 21 and water smoke distribute pipe 2 internal face junctions have for condensate water downstream mist distribute the drip port 211 that pipe 2 internal faces leak down, the condensate water that drip port 211 will be gathered on the fog-proof plate 21 leaks down to be back in the tank 31.

The second way is: described fog-proof plate 21 comprises the center fog-proof plate that is arranged on center in the pipe, the ring-type fog-proof plate that one week of inside pipe wall is fixed, described center fog-proof plate distributes pipe 2 internal faces by extending to water smoke extended leg and water smoke distributes manages 2 and is fixedly connected with, extended leg arranges one at least, also can two or more be set the interval, extended leg just is used for the fixed center fog-proof plate, therefore, extended leg is difficult for wide in radial width, otherwise can affect distributing of water smoke.The adjacent setting with the ring-type fog-proof plate of described center fog-proof plate, and center fog-proof plate and ring-type fog-proof plate are overlapping at the longitudinal component that water smoke distributes tube cavity, longitudinal component is overlapping and refers to that center fog-proof plate and ring-type fog-proof plate projection section in the vertical are overlapping, so that water smoke distributes the water smoke passage of pipe 2 interior formation winding complications.When water smoke runs into the center fog-proof plate, the water mist particle that particle diameter is larger agglomerates on the fog-proof plate of center, then do not turned round from center fog-proof plate periphery by the water smoke of " shielding " and continue to flow, until run into the ring-type fog-proof plate, equally, the larger water mist particle of particle diameter in water smoke part is by ring-type fog-proof plate " shielding ", and the revolution of the water smoke of remaining small particle diameter continues to continue to flow from ring-type fog-proof plate center cavity, and the water smoke that distributes pipe 2 from water smoke at last exports the air that sheds.

As shown in Figure 1, described water smoke distributes pipe 2 and comprises with ultrasonic water smoke and generate the water smoke import 22 of 3 UNICOMs of mechanism and water smoke is dispersed into airborne water smoke outlet 23, do not distribute in the pipe 2 for water smoke is not gathered in water smoke, then described water smoke outlet 23 is positioned at peak and the opening upwards or outside that water smoke distributes pipe 2.It is the unique passages of water smoke that water smoke distributes pipe 2 roads, has just realized and water smoke can be dispersed in the air, can not make again humidifier drip water droplet all around.
