For this reason, on the basis of existing technology, the present invention proposes a kind of humidification fan, comprises the supporting post and the pedestal of fan head, fan head, and said supporting post is supported on the said pedestal; It is characterized in that; The atomizing cavity and the water storage cavity that distribute about being provided with in the said pedestal; Said atomizing cavity and water storage cavity are separated through spacing wall; Be provided with ultrasonic atomizer in the said atomizing cavity, also being provided with on the said pedestal increases the pressure blower of air pressure and can the water in the said water storage cavity be added to the small pump in the said atomizing cavity in said atomizing cavity, have fog output hole on the atomizing cavity top cover of said atomizing cavity; One port of delivery pipe is communicated with said fog output hole, and the another port reaches the anterior locations of said fan head.
Said fan head is to include the motor main body, be connected the flabellum on the motor output shaft and be connected on the motor main body and be clamped in the parts of the safety cage between the said flabellum; Said fan head through be arranged on positioning device on the motor main body be connected to said supporting post the top and can oscillating motion on said supporting post; Said supporting post can be the tubular body of hollow, and electric lead or control electric wire wherein can distribute.Said supporting post can directly be connected on the top cover of said pedestal or after passing said top cover and directly be connected on the diapire of said pedestal, also can be, between the top cover of said pedestal and diapire, column is set, and said supporting post is connected on the said column; When being provided with column structure, minimumly the said supporting post of said upright supports can be utilized, and the top cover of said pedestal can be supported, secondly also can strengthen the structural strength of the diapire and the top cover of said pedestal; Can also stiffening rib be set at the link position between the diapire of said column and said pedestal in addition, thereby improve join strength between the two.
Said ultrasonic atomizer, thus be to be provided with atomizer plate and dither can make water fogging under the control of electrical signal device, and said ultrasonic atomizer is electrically connected with the control system of humidification fan and work under the control of said control system.The atomizer plate of different capacity, its atomizing that makes water fogging (water becomes the shot point of mist) highly is different, and the area of atomizer plate is big more on the whole, and its power is big more, and the average shot point of water is high more; Shot point is high more, and the height of required atomizing cavity is just high more, therefore must be according to the whole height of the said pedestal power of the suitable single atomizer of the height design of atomizing cavity particularly.Secondly in order to strengthen atomization quantity, a plurality of atomizers can be set in said atomizing cavity, thereby and preferably each atomizer be arranged side by side highly consistent, thereby be convenient to the optimum level of water of unified design and control atomizing; In the structure of a plurality of ultrasonic atomizers is set; Not only can being arranged on independently of one another in the said atomizing cavity by a plurality of said ultrasonic atomizers, can also be to concentrate sealing to be arranged on the atomizer that forms a bull formula in the metal shell core of each ultrasonic atomizer; Select bull formula or a plurality of arranged type, can also reduce the height of said atomizing cavity, thereby save material.In addition a fog output hole can be set on the top cover corresponding to each said atomizer, also can the shared fog output hole of several atomizers.With respect to traditional showering atomising device, obviously not only efficient is high but also clean for ultrasonic atomizatio.
Said small pump is to extract the device that the water in the said water storage cavity replenishes in said atomizing cavity, and said small pump is electrically connected with the control system of humidification fan and work under the control of said control system.Said small pump can be arranged in the said water storage cavity or said atomizing cavity in; Also can said small pump be set, in any case as long as can guarantee to make things convenient for installation, maintenance or be convenient to said small pump work at the suitable position outside said water storage cavity and the said atomizing cavity.When said small pump is a kind of submersible pump and be arranged in the said water storage cavity or in the said atomizing cavity time; Be preferably in a hole is set on the spacing wall between said water storage cavity and the said atomizing cavity; Be convenient to and the direct break-through of said small pump water pipe connecting; Shorten flow process, improve the working efficiency of said small pump.
Because the height of the natural drift of atomized steam is difficult to arrive at the position of said fan head; For this reason in order to increase the fed distance of quantity of steam and atomized steam; On said pedestal, set up pressure blower and pressurization air channel, said pressure blower blasts air through said pressurization air channel and then the atomized steam in the said atomizing cavity is taken out of by force in said atomizing cavity; Said pressure blower is electrically connected with the control system of humidification fan and work under the control of said control system.Said pressure blower can be arranged on said pedestal following, side or end face correct position and be positioned at the inlet in said pressurization air channel; And the exhaust outlet in said pressurization air channel is arranged in the atomizing cavity air cavity; Promptly the top position of the maximum water level when said ultrasonic atomizer is worked prevents that the water in the atomizing cavity from pouring in down a chimney in said pressurization air channel; The said dorsad ultrasonic atomizer of exhaust outlet in distribution and said pressurization air channel about the outlet in next said pressurization air channel and said ultrasonic atomizer; Thereby the wind of avoiding exhaust outlet directly blows and hits the blasting process that the atomizing water column that has been shaken by said ultrasonic atomizer promptly prevents to destroy atomized water, improves nebulization efficiency.
The atomizing cavity and the water storage cavity that distribute about being provided with in the said pedestal; Said atomizing cavity and water storage cavity are separated through spacing wall; Be said atomizing cavity and said water storage cavity be positioned at said pedestal and about arrange ground and distribute; Be divided into two cavitys through said spacing wall between said atomizing cavity and the water storage cavity, the top top cover that is provided with separately of said atomizing cavity and water storage cavity, their top covers have separately constituted the top cover of said pedestal jointly.Said spacing wall can be one deck sidewall bodies shared between said atomizing cavity and the water storage cavity, also can be the sidewall bodies that said atomizing cavity and water storage cavity have oneself separately, and said spacing wall is connected on the chamber wall of end cavity volume of said pedestal.In fact said pedestal is the structure that cavity volume at the bottom of the whole shape of peviform adds the top cover combination again; Said spacing wall not only plays compartmentation; And work the stiffening rib effect of the intensity of the end cavity volume of strengthening said pedestal, also can work the supporting effect of the central position of the top cover that supports said pedestal; Secondly can also utilize the water in the said atomizing cavity of said spacing wall overflow to arrive in the said water storage cavity.
The degree of depth of said ultrasonic atomizer submerged work is the problem that must consider, sinks to that deeply then atomizing effect is not good enough, crosses the shallow atomizer plate that then possibly cause burning atomizer.In said atomizing cavity, must design and control well for this reason maximum water level.Said maximum water level is meant that under guaranteeing the optimized nebulization condition water in the said atomizing cavity allows the highest water level of setting.Controlled in order to guarantee the water level in the said atomizing cavity in the design, can the height of the said spacing wall of part be arranged on the highest water level line position, utilize the water in the said atomizing cavity of said spacing wall overflow to arrive in the said water storage cavity; Also can be that the bypass channel hole of overflow (or can) is set on said spacing wall; Thereby force the control highest water level under the bottom land of said bypass channel; Secondly on said atomizer or in the said atomizing cavity, fluid level control device is set, the control lowest water level prevents that atomizer plate from being damaged by dry combustion method.Therefore spacing wall or the bypass channel used dexterously between said atomizing cavity and the said water storage cavity of the present invention directly overflows to water in the said atomizing cavity in the said water storage cavity, and not only simple in structure but also control reliably.Certainly only from controlling the water level of said atomizing cavity, can also there be a lot of schemes to consider, for example pass through level control switch for water etc.What this must further specify be; When said spacing wall is a sidewall bodies that said atomizing cavity and water storage cavity have oneself separately when constituting jointly, can consider to be communicated with the bypass channel that transition tank or water pipe will be separately positioned on the sidewall bodies that said atomizing cavity and water storage cavity have separately.
Said delivery pipe is parts of carrying atomized steam.Because consider that said fan head possibly swing, said for this reason delivery pipe is flexible pipe or flexible metal conduit preferably, and said delivery pipe preferably has smooth interior surface, thereby reduces the loss to atomized steam.
According to said structure, not only can integrity make the end cavity volume that is peviform of said pedestal, and said pedestal overall structure is firm, improve the convenience of manufacturing, assembling and using process; Secondly; Behind splendid attire water in said water storage cavity in the said pedestal and the atomizing cavity; Whole pedestal heavier can be directly as the base fixed parts of fan; Both need not scruple the volume of said water storage cavity again, also not be used in the weighting material of setting up other stable fan heads on the said pedestal, thereby realize promptly firmly saving again material; Pedestal provides good basis for the stable operation of said ultrasonic atomizer again stably; Can too much restrictedly strengthen the volume of said water storage cavity, reduce the number of times that adds water, make said humidification fan more convenient in moving use; Said in addition pedestal is separated into said atomizing cavity and said water storage cavity through spacing wall; Be convenient to automatically control the highest water level of atomizing cavity through the easy structures such as bypass channel on said spacing wall or the said spacing wall; Also be convenient to the water in the said water storage cavity is injected said atomizing cavity; Thereby simplified the structure of liquid level control, also can utilize said spacing wall to strengthen the structural strength of said base.The atomized steam that produces in the said pedestal forces atomized steam to be diffused in the indoor air by means of the fan head that fan head particularly can wave, and has improved the uniformity of the humidification of indoor air.
Certainly, in said water storage cavity, add water for convenient, can add water intake in the appropriate location on the wall body around the said water storage cavity, said water intake can be connected with running water pipe with water pipe through valve; Secondly can also set up castor in the bottom of said pedestal, thereby be convenient on ground directly promote said humidification fan.
Further technological scheme can also be, in said water storage cavity, water-level control apparatus is set, and said water-level control apparatus is controlled the bottom land that the interior water level of said water storage cavity is lower than said bypass channel.Said water-level control apparatus can be the control means of dry reed-pipe class, also can be the parts that float type etc. has similar functions, and said water-level control apparatus parts are electrically connected with the control system of humidification fan and work under the control of said control system.Water level in the said water storage cavity is controlled at below the bottom land of said bypass channel, can prevents that the water in the said water storage cavity from directly flowing into the water level that influences atomizer in the said atomizing cavity through said bypass channel.
Further technological scheme can also be that the diapire of said atomizing cavity is higher than the diapire of said water storage cavity.The diapire of said atomizing cavity is higher than the diapire of said water storage cavity, is meant when said base level is placed on the ground with ground to be the relative height between the diapire of benchmark diapire and the said water storage cavity of seeing said atomizing cavity.Because and do not require the too many water yield of storage in the said atomizing cavity, particularly and do not require that water is too dark,, grow pollutant with cause water in the atomizing cavity to accumulate in a large number throughout the year if the water on the contrary in the said atomizing cavity is too dark.Best user mode is disposable in said atomizing cavity after the water filling, and again through the small pump filled with water, the water before each filled with water in the said atomizing cavity is retained few more good more when waiting water level basically near lowest water level.The height that for this reason the diapire height setting of said atomizing cavity is higher than said water storage cavity; Not only can reduce the moisture storage capacity in the said atomizing cavity; And can relatively improve the moisture storage capacity in the said water storage cavity; Also can utilize because of the diapire position of said atomizing cavity and promote space below the diapire that occurs as part or all of automatically controlled device such as transformer, the circuit board etc. of the said humidification fan of installation; And utilize the weight of water storage cavity of the weight balancing symmetrical position of these electrical parts, wherein said automatically controlled device to be positioned on the outer side wall of diapire of said atomizing cavity.
Further technological scheme can also be; Said atomizing cavity top cover is set to be the structure of peviform; The top cover of said atomizing cavity has roof and sidewall for this reason; Said fog output hole is arranged on the roof of said atomizing cavity top cover, and the sidewall of said atomizing cavity top cover inserts in the said atomizing cavity, and the water of both sides that is positioned at the sidewall of said atomizing cavity top cover can circulate.So in fact, when the said atomizing cavity top cover of installation is on said atomizing cavity; The sidewall of said atomizing cavity is positioned at the periphery of the sidewall of said atomizing cavity top cover; Front and back are arranged even can also be had certain gap, front and back between the two; Said atomizing cavity top cover is that free spiral-lock is in said atomizing cavity; Have bottom gap between the side wall lower ends face of said atomizing cavity top cover and the diapire of said atomizing cavity, thereby make liquid such as the water etc. on the sidewall both sides of said atomizing cavity top cover can walk around this bottom gap free flow, but air above the liquid or atomized steam can only flow out from said fog output hole.Under this kind structure; The water outlet of said small pump preferably is positioned at the outside of the sidewall of said atomizing cavity top cover; Reduce the water wave that said small pump pumps and cause the excessive fluctuation of water level in the said atomizing cavity, but the exhaust outlet in said pressurization air channel must be positioned at said atomizing cavity top cover and be positioned at the top position of maximum water level.Secondly; Highly also there is difference in the atomizing of different water droplets in the process that water is atomized; Individual other water droplet possibly be higher than more than a times of average explosion height; In the use of said atomizer, can not cause damage by contraposition top cover on it in order guaranteeing for this reason, to be preferably in the madial wall that the roof inboard of said atomizing cavity top cover particularly is positioned at above the said atomizer and to set up sheetmetal, the destruction of top cover being caused when keeping out the water droplet explosion; Said sheetmetal can bond, on the inwall that is laid in, also can be fixed on the inwall through other known auxiliary fixing parts or fixed structure.
According to said structure; Because said atomizing cavity top cover is set to be the structure of peviform; In the time of in it tips upside down on said atomizing cavity; Said atomizing cavity top cover relies on its deadweight or assisted gravity to sink in the water in the said atomizing cavity, forms relative sealed space between water in the said atomizing cavity and the said atomizing cavity top cover, and the atomized steam that said ultrasonic atomizer produces can only be overflowed from said fog output hole.Be actually like this and simply utilized water dexterously, simplified sealing configuration greatly as the said atomizing cavity seal arrangement of atomized steam particularly, and only also convenient in the extreme when cleaning inner member such as said atomizing cavity, ultrasonic atomizer.
The humidification fan of another kind of structure comprises the supporting post and the pedestal of fan head, fan head, and said supporting post is supported on the said pedestal; It is characterized in that; Be provided with the atomizing cavity and the water storage cavity that distribute up and down in the said pedestal; Wherein said atomizing cavity be positioned at said water storage cavity above, said atomizing cavity and water storage cavity are separated through spacing wall, are provided with ultrasonic atomizer in the said atomizing cavity; Also being provided with on the said pedestal increases the pressure blower of air pressure and can the water in the said water storage cavity be added to the small pump in the said atomizing cavity in said atomizing cavity; Have fog output hole on the top cover of said atomizing cavity, a port of delivery pipe is communicated with said fog output hole, and the another port reaches the anterior locations of said fan head.
According to said structure; With said atomizing cavity be arranged on said water storage cavity above; And with the lower part of said atomizing cavity mainly as water storage cavity because the moisture storage capacity of said atomizing cavity is fewer, thereby can not cause the top-heavy problem of said humidification fan; Shorten the distance up and down of the fog output hole of said atomizing cavity top cover to said fan head on the contrary, improved fog-supplying amount.Secondly; The water that surpasses highest water level in the said atomizing cavity is earial drainage extremely in the said water storage cavity directly; Simplified the control structure of the highest water level in the said atomizing cavity, for this reason, the sidewall of said atomizing cavity is provided with overflow hole; One end of spill pipe is communicated with said overflow hole, and the other end inserts in the said water storage cavity.
Secondly said atomizing cavity and water storage cavity are separated through spacing wall, and the diapire of in fact said atomizing cavity is exactly the part of the roof or the top cover of said water storage cavity, or overlapping being connected about the roof of the diapire of said atomizing cavity and said water storage cavity.The weight of said like this atomizing cavity directly be pressed in said water storage cavity above; Reduced the influence of the said supporting post that slightly trembles to the atomizing water level of said atomizer; Again can be with disposable independent make or of the end cavity volume of said atomizing cavity with the roof or the together integrated manufacturing of top cover of itself and said water storage cavity; Not only simplify the position structure that is connected between said atomizing cavity and the said water storage cavity, and simplified whole manufacturing process and cost.
Further technological scheme can also be, said water storage cavity comprises the water storage cavity top cover, said atomizing cavity be positioned at said water storage cavity top cover above, the said water storage cavity top cover between said atomizing cavity and water storage cavity forms said spacing wall.
Further technological scheme can also be that said atomizing cavity is around said supporting post setting.So not only can make the weight balancing of said pedestal, and the area of plane of said atomizing cavity is strengthened, and then the more ultrasonic atomizer that can be arranged side by side, improve the quantity of production atomized steam greatly.Said around setting, can be said atomizing cavity itself ringwise, said supporting post passes the intermediate throughholes shape passage of said atomizing cavity; It also can be the lateral location that plural atomizing cavity symmetric figure is distributed in said supporting post.
Because the present invention has These characteristics and advantage, and structure of the present invention can be widely used in the humidification fan series products.
