First 6128 mouthfuls of air-out and total air outlet of the second air outlet 6224 formation air cleaning unit 600.Air cleaning Device 600 can also include at least one leg 6121, and leg 6121 is the enclosure wall of the total air outlet of one of encirclement.One wherein In embodiment, leg 6121 is the part that stretches of the housing part of primary air component 610, and as shown in figure 14, leg 6121 is main The part that stretches of the second sidewall 6126 of air-flow component 610.The first housing 612 at the second air outlet 6224 is smooth Curved surface, when gas is discharged from the first air outlet 6128 and the second air outlet 6224, the gas discharged can also drive air net The air that makeup puts near 600 together flows by the curved surface.The air-flow and the second air outlet of first air outlet 6128 discharge The air-flow of 6224 discharges, during around the hollow position discharge of the first housing 612, can cause wall attachment effect, traction air cleaning dress Put outside 600, i.e. gas near the first housing 612 of hollow and annular, follow in the lump the first air outlet 6128 discharge air-flow and The air current flow of second air outlet 6224 discharge, increases the flow of gas.Make the first air outlet 6128 discharge air-flow, second The gas of (near the first housing 612 of hollow ring-type) outside the air-flow that air outlet 6224 is discharged, and air cleaning unit 600, The hollow position is passed through in the lump.

In one of the embodiments, other air-flow component 620 can be set up in parallel multiple, other air-flow component 620 The first side wall 6124 is overlapped with the second sidewall 6126 of adjacent other air-flow component 620, and/or other air-flow component 620 second Side wall 6126 is overlapped with the first side wall 6124 of adjacent other air-flow component 620.In different other air-flow components 620, Ke Yishe The filter 626 of difference in functionality is put, for purifying different classes of, various concentrations pollutants.By different other air-flow components 620 Filter 626 gas, different gas sources can be originated from, the air intake position restriction of other air-flow component 620 warp The scope of the air of filter 626 is crossed, can be with more targeted carry out air cleaning.The air intake position of other air-flow component 620 Can be with the need for according to site environment air cleaning, or the concentration of pollutant or source change, neatly tune manually or electrically Save different positions.In one of the embodiments, the second air inlet structure 624 can be as needed, and use can bend, can With flexible material and structure, the second air inlet structure 624 can in a tubular form, and the second air inlet structure 624 can extend or shorten, Can flexibly it transfer.Primary air component 610 can drive multiple other air-flow components 620, primary air component 610 and multiple sides simultaneously Air-flow component 620 is set up in parallel, and primary air component 610 can be located at one end arranged side by side, can also be clipped in multiple other air-flow components In the middle of 620.

With reference to above-described embodiment, present invention design is to break through setting for traditional filter that is arranged in parallel in layer Thought is counted, the effect of " leaking out ", and " leaking out " effect deliberately caused using this is deliberately caused, changes into a Venturi effect Air outlet, make the air cleaning unit of the present embodiment, can double gas flow, even in using relatively low torque motor drive Dynamic blower fan, or non-backward-curved blade fan blower fan is used, still can be with effective operation.Gas with pollutant, can effectively wear Cross the higher filter of windage, so as to effectively be purified, while can lower the power consumption brought by the motor of higher force square and Noise problem.

Other air-flow component in the air cleaning unit or air cleaning unit of the present embodiment can arbitrarily coordinate outside Air generation plants use, air generation plants can include the blower fan of the motor of different torques, and air generation plants can be with It is electric fan, dehumidifier, moisture releasing machine, cool wind fan, air conditioner, warm-air drier etc..The air cleaning unit of the present embodiment can make sky When jet power unit is run, the effect with purification air, and the windage of filter, the blower fan of air generation plants is not influenceed The load of motor.In one of the embodiments, the shape of air cleaning unit, it is big less, thick book equal-specification, can be mark Huaihe River Specification, without specially to coordinate different types of air generation plants, production different model, the air cleaning unit of shape And/or filter.

The air cleaning unit of the present embodiment can also coordinate no fan-leaf fan, air multiplier, air amplifier (Air Amplifier) use.Exemplified by without fan-leaf fan, air cleaning unit is arranged on to the wind outlet of no fan-leaf fan, makes no fan When blade fan is run, air can be purified simultaneously, it is not necessary to the extra energy, will not also increase no fan-leaf fan motor it is negative Carry, will not also weaken the wind flow of no fan-leaf fan.On the contrary, can be produced without fan-leaf fan with the air cleaning unit of the present embodiment The effect of one collaboration, the air-flow increase of no fan-leaf fan enters the flow of the air of filter, increases rate of ventilation indirectly, plus Big pure air output rating (Clean Air Delivery Rate).Without fan-leaf fan equivalent to the primary air in the present embodiment Component.

Again by taking air amplifier as an example, air cleaning unit is arranged on to the wind outlet of air amplifier, amplifies air Utensil has the function of air cleaning.However, in the effect of this extra improvement environment, the housing for not weakening air amplifier Air flow pressure, does not change the external form of the hollow circular housing of air amplifier yet, and wall attachment effect will not disappear.Air Purifier and air amplifier are used in combination, and do not consume the extra energy, also do not increase the motor of air amplifier Load, will not also weaken the wind flow of air amplifier, can but make air amplifier, arbitrarily coordinate different type, different thickness Thin filter, adds the function of purification air.

General air amplifier, with traditional electric fan, dehumidifier, moisture releasing machine, cool wind fan, air conditioner, warm-air drier etc. Electrical installation containing blower fan is different, and air filter can be transformed into by installing filter additional.Reason be air amplifier mainly by The path of two air flows, to reach the effect of ventilation, one path is to take up high pressure by high torque, high pressure force motor Air, this inlet air flow path flows in housing, if installing filter additional in this inlet air flow path, can subtract The pressure that weak air flows in housing, the air of low-pressure is sent out from Venturi nozzle, it is impossible to is reached and is affected surrounding air Effect.Another empty flow path, is to produce wall attachment effect with the external form of hollow circular housing, drives the air of surrounding to flow through hollow shell Body, if adding filter in this inlet air flow path, will change the external form of hollow circular housing, wall attachment effect It can be disappeared because of the change of external form, surrounding air will not be flowed by traction.Embodiment shown in Figure 11 to Figure 14, by with air Amplifier is arranged side by side other air-flow component and cleverly overcomes technical barrier, air amplifier is combined with filter.

In above-described embodiment, into primary air component and into the gas of other air-flow component, it can be originated from different Air source, can be more effective to carry out clearly with according to the second air intake vent position, being defined through the scope of the air of main filter Air cleaning.Second air intake vent, can be with the need for according to site environment air cleaning, or the concentration of pollutant or source change, Adjust different positions.

The air cleaning unit of the present embodiment, the air-flow exported from the first air outlet and the second air outlet, if being necessary again Further filtered, can also the air cleaning unit exterior space, connection or add an external filter. In one embodiment, righteous style and practice pressure is caused to exempt from the windage of external filter, stops the first air outlet and the output of the second air outlet Air-flow, weaken the negative pressure of negative pressure space, when additional external filter, volumes can also be set in following one or more positions Outer air exhauster or hair-dryer：(1) in the downstream position of external filter.(2) upstream position of external filter and the first air-out The downstream position of mouth and the second air outlet.Extra air exhauster or hair-dryer are set, external filter can be passed through with secondary air, together When prevent space between the first air outlet and/or the second air outlet and external filter from producing ratio the first Room and/or second Room Big air pressure and the negative pressure for weakening negative pressure space.

The air cleaning unit of the present embodiment, is the air-flow for entering other air-flow component by the air of filter cleaning, without It is that gas in the air-flow into primary air component, primary air component can be produced by blower fan.It is different from conventional art, pollution Air is not used as dealing with the filter containing higher windage without flowing through blower fan, the motor of blower fan.Therefore, blower fan or horse are protected Reach, extend the service life of air cleaning unit, air cleaning unit will not be by the air pollution containing pollutant, also will not be because Deal with high capacity filter for a long time and damage.

In above-described embodiment, the first housing, in shape is tightened up gradually, is conducive to improving the first air-out at the first air outlet The flowing velocity of gas at mouthful, and then produce bigger negative pressure.Its principle is as follows：At most narrow place, the gas of the first air outlet output The dynamic pressure (velocity head) of stream reaches maximum, and static pressure (Resting Pressure) reaches minimum value.The output of first air outlet The speed of air-flow rises because of the relation for cross-section variation of shoving, and first will can be undergone in the same time and go out by entirely shoving Air port reduces process, thus pressure is also in the reduction of same time.And then pressure differential is produced, this pressure is at the second air outlet Gas provides an external suction, so that negative pressure space generates negative pressure.Therefore, if being in receive gradually at the first air outlet Tight shape, negative pressure space can produce larger negative pressure.Primary air concentrator 213 and primary air concentrator in above-described embodiment 414 principle is ibid.

In above-described embodiment, leg is also included at total air outlet of air cleaning unit, leg is fence, surround the One air outlet and the second air outlet, or total air outlet that the second air outlet and primary air concentrator are constituted.It is preferred that leg is higher than First air outlet and the second air outlet.

When the first air outlet exports the air-flow of high speed and produces pressure differential, leg can concentrate pressure differential, Jin Ercong A stronger external suction is generated in second air outlet.Otherwise, partial pressure difference may be sacrificed the second air port of work traction The air-flow of place slightly outside, lowers the external suction in the second air outlet, reduces vacuum effect.

The cross-sectional area of leg can be invariable, or in shape is expanded gradually, if leg cross-sectional area is in expand gradually One end of big shape, nearly first air outlet in the most narrow place of leg and the second air outlet, the most wealthy place of leg closely leads to one end of exterior space, Because maximum pressure is in the most narrow place of leg.Wherein, leg can stretching for the housing part of primary air side component The part that stretches of part or the housing part of other air-flow component.
