To distinguish from the air inlet and the air outlet of the air conditioner for better description, hereinafter, the air inlet of the housing 110 is defined as a module air inlet 111, and the air outlet of the housing 110 is defined as a module air outlet 112. The housing 110 has a substantially cylindrical shape extending in the up-down direction, for example, the housing 110 may have a square shape, a circular shape, or the like. In addition, the housing 110 may have a structure with both ends sealed. In one embodiment, the module air inlet 111 is disposed on the periphery of the housing 110, and the opening at the top end of the housing 110 is the module air outlet 112, so as to realize air inlet at one end and air outlet at the other end. Of course, in other embodiments, the module air outlet 112 may be disposed on the peripheral side of the housing 110. Preferably, the fan 150 may be disposed on the housing 110 to accelerate the circulation of air in the cleaning air duct 113, so as to improve the cleaning efficiency. It should be noted that the directional indications (such as upper, lower, left, right, front and rear … …) mentioned in the embodiments of the present invention are only used to explain the relative position relationship between the components, the motion situation, etc. in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indication is changed accordingly.

Referring to fig. 1 and 2, the air purification module includes a housing, a spray head, a rotating body, an IFD purification device, and a negative ion generator. The housing 110 has a module air inlet 111, a module air outlet 112 and a purification air duct 113, the module air inlet 111 is disposed at the lower end of the housing 110, the module air outlet 112 is disposed at the upper end of the housing 110, the purification air duct 113 is communicated with the module air inlet 111 and the module air outlet 112, so that the air flow flows from bottom to top in the purification air duct 113, the spray head 190 is installed in the purification air duct 113, and is suitable for being communicated with a water source, the rotator 120 is rotatably installed in the purification air duct 113, the rotator 120 is disposed below the spray head 190, the rotator 120 is used for throwing out the water through rotation when the spray head 190 sprays the water onto the rotator 120, the anion generator 270 is disposed in the purification air duct 113, the IFD purification device 260 is disposed in the purification air duct 113, and the anion generator 270 and the IFD purification device 260 are disposed.

In this embodiment, when the air purification module 100 purifies air, the air flow flows out from the bottom to the top in the purification air duct 113, and at the same time, the spray head 190 sprays water from the top to the bottom, the rotating body 120 rotates at a high speed to throw out the water falling thereon at a high speed, and the thrown water is refined into countless water drops with extremely small particle size. The water sprayed by the spray head 190 and the water thrown out by the rotating body 120 collide with the air flow flowing from bottom to top in the opposite direction, so that the relative speed of the water and the air flow in opposite direction is increased, and therefore a large amount of impurities in the air flow are absorbed by water drops and taken away, and the water-throwing and air-purifying effect by the supergravity is realized. For example, fine particles, pollen, biological bacteria, volatile organic compounds (such as formaldehyde and benzene) in the purified air. In addition, the water drops are mixed into the air, and the effect of humidifying the air can be achieved.

The IFD purification apparatus 260 applies a large attraction force to the charged particles moving in the air by using a strong electric field with a dielectric material as a carrier, and adsorbs moving particles in the air while generating only a small air flow impedance, and simultaneously collects and kills bacteria, microorganisms, etc. attached to the particles in the strong electric field. The anion generator 270 generates anions to make the indoor air healthier and to charge particles in the air, contributing to the purification effect of the IFD purification apparatus 260. The air entering the purifying air duct 113 is first washed and purified by the rotating body 120 to adsorb large particles in the air. Through after IFD purifier 260 adsorbs remaining granule in the air, promotes air purification module 100's purifying effect, alleviates IFD purifier 260's use burden, practices thrift the electric quantity, prolongs IFD purifier 260's life.

On the basis of the above embodiment, referring to fig. 3, the cross section formed by the circumferential profile of the nozzle 190 is gradually reduced from top to bottom, and a plurality of water spraying holes are arranged through the circumferential wall of the nozzle 190.

Because the cross section formed by the circumferential profile of the spray head 190 is gradually reduced from top to bottom, the spray head 190 has a large wide water spraying angle, the water spraying range of the spray head 190 is effectively enlarged, water is sprayed to the rotating body 120 in all directions, and the rotating body 120 is ensured to obtain sufficient water volume to throw off water and clean air flow. It should be noted that the cross section of the shower head 190 should be a section perpendicular to the flow direction of the air flow in the purge air duct 113 (i.e., upward and downward). As to the specific shape of the spray head 190, for example, but not limited to: the nozzle 190 is tapered from top to bottom; or, the spray head 190 is arranged in a hemispherical shape from top to bottom; alternatively, the nozzle 190 is disposed in a truncated cone shape from top to bottom. The above three design manners of the nozzle 190 can all realize that the cross section formed by the circumferential profile of the nozzle 190 is gradually reduced from top to bottom. For conventional cylindrical shower nozzle 190, the utility model discloses an adopted shower nozzle 190 has bigger water spray wide angle, can obtain bigger water spray scope.

In addition, because the spray head 190 is located above the rotating body 120, compared with the conventional method of inserting the water spray pipe into the rotating body 120 along the rotation axis of the rotating body 120, the user only needs to disassemble the housing 110 or stretch the hand to enter the purifying air duct 113, and then the spray head 190 can be cleaned, or the spray head 190 is cleaned after being disassembled, and the rotating body 120 does not need to be disassembled, so that the difficulty of cleaning the spray head 190 is greatly reduced, and the cleaning is convenient.

When the linear velocity of the outer edge of the rotating body 120 is too small, the velocity of the water thrown out by the rotating body 120 is small, and the air purification effect is poor, and when the linear velocity of the outer edge of the rotating body 120 is too large, the energy consumption of the rotation of the rotating body 120 is large and the noise generated is large, and the improvement of the air purification effect by continuously increasing the linear velocity of the outer edge of the rotating body 120 is small.

Therefore, in the present embodiment, when the air purification module 100 is required to operate, the linear velocity of the outer edge of the rotating body 120 is 10m/s to 45 m/s. Such as but not limited to: 10m/s, 15m/s, 18m/s, 20m/s, 25m/s, 30m/s, 35m/s, 38 m/s. The linear velocity of the outer edge of the rotating body 120 is limited to 10m/s to 45m/s, so that the velocity of the water thrown out by the rotating body 120 is ensured to be high, and the noise generated by the rotation of the rotating body 120 is small.

Particularly, when the air purification module 100 works, the linear velocity of the outer edge of the rotating body 120 is 20m/s to 30m/s, and at this time, the rotating body 120 has the advantages of good purification effect, reasonable energy consumption and low noise. Such as but not limited to: 22m/s, 24m/s, 26m/s, 28 m/s.

Referring to fig. 3 and 4, in one embodiment, to facilitate the installation of the nozzle 190, the air purification module 100 further includes a mounting frame 240 located above the rotating body 120, wherein the mounting frame 240 is fixedly connected to the inner wall of the purification air duct 113, and the nozzle 190 is installed on the mounting frame 240. The specific structure of the mounting frame 240 may be designed according to the response requirement, and is not particularly limited herein. The nozzle 190 may be fixed to the mounting bracket 240 by a hanging or screwing structure, and may be designed correspondingly by combining with the structure of the mounting bracket 240.

Optionally, the air purification module 100 further includes a water supply pipe 251 mounted to the mounting bracket 240, the water supply pipe 251 having a water inlet end and a water outlet end, the water inlet end of the water supply pipe 251 being adapted to communicate with a water source, and the water outlet end being inserted into the mounting sleeve 241.

Since the water pipe 251 is mounted on the mounting bracket 240, when the nozzle 190 is coupled to the water outlet end of the water pipe 251, the nozzle 190 is hung on the mounting bracket 240 in a hanging manner. The spray head 190 is rotatably connected to the water pipe 251 by a screw or an interference connection. Specifically, the nozzle 190 is threadedly engaged with the water supply pipe 251, so that the nozzle 190 can be disassembled by rotating, which is simple and convenient to operate.

There are various ways in which the water supply pipe 251 is mounted to the mounting bracket 240. For example, the water supply pipe 251 may be tied to the mounting bracket 240 by a string, etc., or mounted to the mounting bracket 240 by a snap structure or a screw structure. In this embodiment, referring to fig. 3 and 4, a portion of the water supply pipe 251 near the water outlet end is bent to form a bent section 252, and the water supply pipe 251 is hung on the mounting frame 240 through the bent section 252. The installation mode does not need a buckle structure or a screw connection structure, and is simple in structure and convenient to install.

Based on the above embodiment, the air purification module 100 further includes the water supply tank 250 located below the rotating body 120, the water supply tank 250 is connected to the water inlet end of the water supply pipe 251, and the water supply tank 250 serves as a water source to supply water to the spray head 190 and is sprayed from the spray head 190 to the rotating body 120 to provide a sufficient amount of water to the rotating body 120. Of course, the water supply tank 250 is not essential, and the water source may be a water source (such as a water tank or a water pan) of an indoor unit of an air conditioner, or a water storage source provided by the rotary body 120.

Because the diagonal flow wind wheel 130 is arranged below the module air outlet 112, the fan blades of the diagonal flow wind wheel 130 are prevented from aligning with the module air outlet 112, and further the fan blades of the diagonal flow wind wheel 130 are effectively prevented from being touched by fingers of children stretching from the module air outlet 112. Meanwhile, as the diagonal flow wind wheel 130 is arranged below the module air outlet 112, a certain distance exists between the diagonal flow wind wheel 130 and the module air outlet 112, noise generated by the diagonal flow wind wheel 130 can be reduced, and thus noise of the air purification module 100 is reduced.

On the basis of the above embodiment, the anion generator 270 and the IFD cleaning device 260 are located below the mixed flow wind wheel 130. Thus, when the air passes through the anion generator 270, the anion generator 270 releases anions to agglomerate particles in the air.
