Referring to fig. 1 and 2, the present invention provides an embodiment of an air purification apparatus. The air purification device can simplify the operation procedure of replacing the filter screen so as to replace the filter module. The air purification device can be applied to an indoor unit of an air conditioner (an indoor unit of a wall-mounted air conditioner or an indoor unit of a floor-type air conditioner) and can also be applied to other air treatment equipment.

Referring to fig. 2 to 4, in an embodiment of the air purification apparatus 100 of the present invention, the air purification apparatus 100 includes a housing 110, a fan module 120 and a plurality of filter modules 130. The housing 110 has an air inlet (an indoor air inlet 111 or a fresh air inlet 112), an air outlet 113, and an air purification duct 114 extending in the vertical direction, wherein the air purification duct 114 communicates the air inlet with the air outlet 113. The fan module 120 is disposed in the air cleaning duct 114. A plurality of filter modules 130 are stored in the housing 110, and the filter modules 130 are movable relative to the intake vents to switch between a storage position 131 and an operating position 132, wherein the operating position 132 is between the intake vent side of the fan module 120 and the intake vents.

Specifically, the cross section of the housing 110 may be square or circular, and the lower end of the housing 110 is provided with an air inlet, which is provided with an air inlet grille 160; an air outlet 113 is formed at the upper end of the housing 110.

Therefore, the utility model discloses an air purification device 100, the operating procedure of changing the filter screen is comparatively simple, need not to carry out the operation of taking out to put into many times, is convenient for change filter module 130.

Referring to fig. 1 to 3, in an embodiment, the plurality of filtering modules 130 are configured as a plurality of filtering modules 130 with the same function. That is, the plurality of filter modules 130 may each filter the same contaminants, such as PM2.5, or formaldehyde, etc. Specifically, the plurality of filtering modules 130 may be filtering nets at the same time; alternatively, the plurality of filter modules 130 may be HEPA mesh or formaldehyde treatment modules.

Of course, in other embodiments, the plurality of filtering modules 130 may also be configured as a plurality of filtering modules 130 with different functions, so as to respectively filter different pollutants. For example, one of the filter modules 130 is used for filtering PM2.5, another filter module 130 is used for filtering formaldehyde, and another filter module 130 is used for filtering microorganisms, etc.

Based on the above embodiment, the plurality of filtering modules 130 are any one or a combination of a filtering screen module, a HEPA screen module, a formaldehyde treatment module, and an electrostatic dust removal module. If the plurality of filter modules 130 are all filter screen modules, the plurality of filter screen modules may also be designed to have different precision filter screens. For example, the plurality of filter screen modules include a primary filter screen module, a secondary filter screen module, a high efficiency filter screen module, and an activated carbon filter screen module.

Wherein, selecting the corresponding filtering module 130 according to the pollutant concentration, and moving the filtering module 130 to the working position 132 corresponding to the filtering module, specifically includes:

when the concentration of pollutants in the environment is in a first preset interval, controlling all the filter modules 130 to be kept or moved at the storage position 131;

when the concentration of the pollutants in the environment is in a second preset interval, controlling the primary filter screen module to move to the corresponding working position 132;

when the concentration of the pollutants in the environment is in a third preset interval, controlling the middle-effect filter screen module to move to a corresponding working position 132;

when the concentration of the pollutants in the environment is in a fourth preset interval, controlling the high-efficiency filter screen module to move to a corresponding working position 132;

when the concentration of the pollutants in the environment is in a fifth preset interval, controlling the middle-effect filter screen module and the high-effect filter screen module to move to corresponding working positions 132;

The number of the storage boxes 170 is plural, and the plurality of storage boxes 170 correspond to the plurality of filter modules 130 one by one.

It is further contemplated that during air filtration of the filter module 130 in the operating position 132, filter material (contaminants) filtered by the filter module 130 may adhere to the filter module 130 and may fall downwardly from the filter module 130 into the housing 110, contaminating other components.

To avoid this, the storage position 131 and the storage box 170 are both disposed below the working position 132, and the opening of the storage box 170 is opened upward (as shown in fig. 1) for receiving the filter media falling from the filter module 130 after the corresponding filter module 130 is moved to the working position 132. That is, the storage case 170 serves as a receiving case for receiving the filter module 130 at a previous stage and serves as a waste case for receiving contaminants at a later stage.
