When the airflow is discharged from the first air outlet of the main airflow component, the air at the second air outlet of the side airflow component is drawn to flow, a venturi effect is generated, the negative pressure space generates negative pressure, and the air outside the side airflow component passes through the filter and is discharged from the second air outlet. The venturi effect is utilized to drive the gas to flow, so that the energy consumption of the air purification device can be reduced. When a plurality of filters with different wind resistances are used, a plurality of side airflow assemblies can be correspondingly arranged, and excessive wind pressure is prevented from being applied to all the filters for matching with the filter with the larger wind resistance, so that energy waste is avoided. Meanwhile, all gas entering the bypass airflow assembly passes through the filter, so that the purification efficiency is improved.

Wherein in one embodiment, other air-flow component 620 can be the multiple being set up in parallel, other air-flow component 620 The first side wall 6124 overlaps with the second sidewall 6126 of adjacent other air-flow component 620, and/or other air-flow component 620 second Side wall 6126 overlaps 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, purification of air can be carried out with more targeted.The air intake position of other air-flow component 620 Can with the need for according to site environment purification of air, or pollutant concentration or source change, neatly tune manually or electrically Save different positions.Wherein in one embodiment, the second air inlet structure 624 can 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 transfer.Primary air component 610 can simultaneously drive air-flow component 620 by multiple, by primary air component 610 and multiple Air-flow component 620 is set up in parallel, and primary air component 610 may be located at one end arranged side by side, it is also possible to be clipped in multiple side air-flow component In the middle of 620.

With reference to above-described embodiment, present invention design is to break through setting for traditional filter that is in layer arranged in parallel Meter thought, deliberately causes the effect of " leaking out ", and " leaking out " effect deliberately caused using this, changes into a Venturi effect Air outlet, make the air cleaning unit of the present embodiment, can double gas flow, even if using relatively low torque motor drive Dynamic blower fan, or using non-post to bent leaf formula blower fan, still can be with effective operation.Gas with pollutant, can effectively wear Cross windage filter higher, so as to effectively being 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 Jet power unit run when, the effect with purify air, and filter windage, the blower fan of air generation plants is not influenceed The load of motor.Wherein in one embodiment, 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 without fan-leaf fan, air multiplier, air amplifier (Air Amplifier) use.As a example by without fan-leaf fan, air cleaning unit is arranged on the wind outlet without fan-leaf fan, made without fan When blade fan runs, can be while purify air, it is not necessary to the extra energy, will not also increase the negative of the motor without fan-leaf fan Carry, will not also weaken the wind flow without fan-leaf fan.Conversely, can be produced with the air cleaning unit of the present embodiment without fan-leaf fan One effect of collaboration, the air-flow without fan-leaf fan increases the flow of the air for entering filter, rate of ventilation is increased indirectly, plus Big pure air output rating (CleanAir Delivery Rate).Without fan-leaf fan equivalent to the primary air group in the present embodiment Part.

Again by taking air amplifier as an example, air cleaning unit is arranged on the wind outlet of air amplifier, amplifies air Utensil has the function of purification of air.However, this extra effect for improving environment, without in the housing for 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 without the extra energy is consumed, 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, increased the function of purify 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 installing filter additional can be transformed into air filter.Reason be air amplifier mainly by Two paths of air flow, 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 is flowed in housing, if installing filter additional in this inlet air flow path, can be subtracted The pressure that weak air flows in housing, the air of low-pressure is sent out from Venturi nozzle, it is impossible to reaches and affects 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 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 the gas into other air-flow component, can be originated from different Air source, clearly with according to the second air intake vent position, being defined through the scope of the air of main filter can more effectively be carried out Purification of air.Second air intake vent, can with the need for according to site environment purification of air, or pollutant concentration or source change, Adjust different positions.

The air cleaning unit of the present embodiment, from the air-flow that the first air outlet and the second air outlet are exported, if being necessary again Further filtered, can also be connected or added an external filter in the exterior space of the air cleaning unit. 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, volume 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 between the first air outlet and/or the second air outlet and external filter the Room of space producing ratio first and/or second Room Big air pressure and weaken the negative pressure of 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 the air-flow for entering primary air component, the gas in 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 windage higher 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 and damage for a long time.

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 of cross-section variation of shoving, and entirely shoving will can experience first and go out in the same time 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.
