The utility model provides an air purification module.

In the embodiment of the present invention, as shown in fig. 1 and 2, the air purification module 100 includes a housing 1, a rotary body 2, an electrostatic dust collection assembly 3 and a moisture filter assembly 4,

the shell 1 is provided with an air inlet 11, an air outlet 12 and a purification air duct 13 which is used for communicating the air inlet 11 with the air outlet 12;

the rotating body 2 is rotatably arranged in the purifying air duct 13, and the rotating body 2 is suitable for throwing out water by rotating when the water is sprayed on the rotating body 2;

the electrostatic dust collection assembly 3 is arranged in the purification air duct 13; and

the water vapor filtering component 4 is arranged in the purifying air duct 13 between the rotating body 2 and the electrostatic dust collecting component 3, and the water vapor filtering component 4 is used for preventing water vapor on one side of the rotating body 2 from blowing to the electrostatic dust collecting component 3.

In the present embodiment, the shape of the housing 1 may be various, for example, the cross section may be circular, oval, rectangular, etc., and in order to better fit with the air conditioner, the shape of the housing 1 may be set according to the model of the air conditioner used specifically, and is not limited herein, and the following embodiments are described by taking the housing 1 as a cylinder. The casing 1 may have a structure with openings at both ends, the openings at both ends are used as the air inlet 11 and the air outlet 12, the casing 1 may also have a structure with openings at both ends, the air inlet 11 is provided on one circumferential side of the casing 1, and the air outlet 12 is provided on the other circumferential side of the casing 1. There are various shapes of the intake opening 11 and the outtake opening 12, such as a circle, an ellipse, a square, a polygon, a porous type, etc., and there is no particular limitation. The air inlet 11 comprises a fresh air inlet which is communicated with the outdoor; and/or the indoor air inlet 11 is communicated with the indoor space through the indoor air inlet 11. Because the rotating body 2 is installed in the casing after being wrapped by the casing 1, the casing 1 can prevent water thrown by the rotating body 2 from flowing to the inner wall of the casing, so that other parts on the inner wall of the casing can be prevented from being wetted and damaged. In addition, air intake 11 sets up to a plurality ofly, and along casing 1's circumference interval distribution, realizes a plurality of positions air intakes of circumference, better increase with the area of contact of water.

The rotating body 2 is rotatably arranged in the cleaning air duct 13, and the rotating body 2 is adapted to throw water out by rotation when the water is sprayed on the rotating body 2, i.e. the rotating body 2 is adapted to make the water leave the rotating body 2 after centrifugal movement when the rotating body rotates. This rotator 2 can comprise one or more carousel, when water sprays the carousel, because rotator 2 highly rotates for water cutting on the carousel gets rid of the internal face to casing 1 for tiny water particle, thereby the air current in the process purification wind channel 13 can contact and fuse with tiny water particle, and then reaches the mesh of washing filtered air. The rotary body 2 may be provided with a ventilation structure, and a screen or mesh (not shown) may be laid thereon to cut and purify fine water particles.

The drainage to the water vapor filtering component 4 can be realized by the modes of a water diversion component, guiding the water of the water vapor filtering component 4 to the inner wall of the shell 1 and the like, so that the effectiveness of the water vapor filtering component 4 is ensured. It will be appreciated that dry air is more likely to charge dust due to friction, aerosol adsorption in the air, etc. Thereby filter the tiny particulate matter in the air of steam and be changeed in being adsorbed by electrostatic precipitation subassembly 3, and then improve electrostatic precipitation subassembly 3's work efficiency and purifying effect.

Specifically, referring to fig. 1, the air purification module 100 further includes a driving device 7 connected to the rotating body 2, and an output shaft of the driving device 7 is connected to the rotating body 2 to drive the rotating body 2 to rotate along a rotation axis thereof. A drive device 7 is mounted to the housing 1, the drive device 7 being connected to the rotary body 2 to drive the rotary body 2 in rotation about its axis of rotation. The driving device 7 is embodied as a motor or other driving element capable of driving the rotation of the rotation body 2. In practical applications, the peripheral linear velocity of the rotating body 2 is greater than or equal to m/s and less than or equal to 45m/s, such as 10m/s, 15m/s, 18m/s, 23m/s, 28m/s, 35m/s, 45m/s, etc. Preferably from m/s to m/s, such as may be 20m/s, 22m/s, 25m/s, 27m/s, 30m/s, and the like. So, can make water by broken up fully, effectively increase the distribution volume of water droplet and water smoke, can reduce the noise of production again, improve the practicality.

The utility model discloses air purification module 100 is through making 2 rotatable settings of rotator in purifying air duct 13, then when rotator 2 is rotatory, gaseous pollutants such as great particulate matter and formaldehyde in a large amount of small water droplets that outwards throw away can effectively catch and filter the air of rotator 2 of flowing through, and locate the electrostatic precipitation subassembly 3 that purifies in the air duct 13 and can catch the tiny particulate matter (PM2.5 and following granule) that purifies the air in the air duct 13, harmful substance such as bacterium, thereby air purification module 100 can be effective and comprehensive gaseous pollutants such as particulate matter and formaldehyde in the clean room, and really accomplish the purification of no consumptive material. Simultaneously, through set up steam filtering component 4 between rotator 2 and electrostatic precipitation subassembly 3, steam filtering component 4 can block that the steam of rotator 2 one side blows to electrostatic precipitation subassembly 3 to the air that blows to electrostatic precipitation subassembly 3 is dry air, and then can improve the work efficiency and the adsorption effect of electrostatic precipitation subassembly.

In one embodiment, as shown in fig. 1 and 9, the electrostatic dust collecting assembly 3 is disposed between the rotating body 2 and the air outlet 12.

In this embodiment, the electrostatic dust collecting assembly 3 is disposed between the rotating body 2 and the air outlet 12, so that the air flow entering the air purifying duct 13 from the air inlet 11 is firstly filtered by the rotating body 2, and then is filtered by washing, so as to capture and filter out larger particles (above PM 2.5), formaldehyde, etc. in the air, and then flows through the electrostatic dust collecting assembly 3, so as to capture particles of small particles (below PM 2.5) in the air primarily filtered by the rotating body 2. So for electrostatic precipitation subassembly 3's function obtains optimized use, and electrostatic precipitation subassembly 3 can detach the particulate matter effectively, can not cause the dust to pile up and become invalid because of adsorbing big particulate matter, thereby has reduced electrostatic precipitation subassembly 3's cleaning frequency.

Further, the air inlet 11 is located at the lower end of the housing 1, the air outlet 12 is located at the upper end of the housing 1, and the electrostatic dust collection assembly 3 is located above the rotating body 2.

In this embodiment, the water thrown away by the rotating body 2 drops downward due to the action of gravity, so that the air inlet 11 is located below the housing 1, the air inlet direction is inconsistent with the dropping direction of the water drops, and the air flow is prevented from being discharged from the air outlet 12 while being mixed with a large amount of water drops. And then reduce the work load of steam filtering component 4, guarantee the work stability of steam filtering component 4 effectively. It should be noted that, since the purifying air duct 13 may be a straight tube or a bent type, the upper and lower directions referred to herein refer to a relative up-down position relationship, and do not necessarily refer to the right upper and right lower directions, if the purifying air duct 13 is a right-angle bent type, the rotating body 2 may be located at a straight section of the purifying air duct 13, and the electrostatic dust collecting assembly 3 may be located at a bent section of the purifying air duct 13. Preferably, the housing 1 is provided in a straight cylindrical shape, and the electrostatic dust collection assembly 3 is positioned directly above the rotary body 2. Therefore, the whole structure is more compact, the transverse space occupied by the indoor air conditioner can be avoided, and the occupation of the indoor transverse space is reduced.

If the electrostatic dust collecting assembly 3 is disposed under the rotary body 2, the filtering effect of the fine particles of the electrostatic dust collecting assembly 3 is poor, and a relatively strong electric field is required to remove large particles and small particles in the air, so that the load of the electrostatic dust collecting assembly 3 is too large. Through making electrostatic precipitation subassembly 3 set up in the top of rotator 2, then the air current that gets into in the air purification duct 13 from air intake 11 firstly filters through rotator 2 washing, catches and filters great particulate matter (PM2.5 above), formaldehyde etc. in the air, then flows through electrostatic precipitation subassembly 3 again, catches the granule of the little particulate matter (PM2.5 and below) in the air after being filtered by rotator 2 preliminary. So for electrostatic precipitation subassembly 3 can effectual purification through the rotator 2 washing little particulate matter after filtering, need not strong electric field, and electrostatic precipitation subassembly 3's load is little, makes electrostatic precipitation subassembly 3's function obtain the use of optimization. The electrostatic dust collection assembly 3 can effectively remove small particles, and the dust accumulation failure caused by the adsorption of large particles is avoided, so that the cleaning frequency of the electrostatic dust collection assembly 3 is reduced.

In other embodiments, the air inlet 11 may be located at the upper end of the housing 1, the air outlet 12 is located below the housing 1, and the rotating body 2 is located above the electrostatic dust collecting assembly 3. The moisture filter assembly 4 can block water drops and moisture falling from the rotary body 2 and prevent the moisture from blowing toward the electrostatic dust collecting assembly 3. At this time, drainage can be achieved by providing a water diversion structure, a water receiving structure, directing water droplets to the inner wall surface of the casing 1, and the like.
