Alternatively, the first cleaning module 210 may be disposed between the first air inlet side and the first air inlet 111 a. When the first purifying module 210 is disposed between the first air inlet side and the first air inlet 111a, the casing 100 has a better protection effect on the first purifying module 210, and the first purifying module 210 can filter and sterilize air passing through the first air inlet 111 at first, thereby preventing excessive impurities or dust from entering the first centrifugal fan 800 and affecting the normal operation of the first centrifugal fan 800. The first purification module 210 may specifically include a purification and filtration module and a sterilization module, and the purification and filtration module is used to filter dust, particles, impurities, and the like in the air. The sterilization module is a module capable of sterilizing bacteria, viruses, and the like in the air. The purification and filtration module can be close to the setting of first air intake 111a, and the module of disinfecting can be located and purify the one side that the filtration module deviates from first air intake 111a to after the air got into first air intake 111a, can filter some dusts, impurity etc. at first through the purification and filtration module, and then carry out germicidal treatment through the module of disinfecting again, thereby further ensure to blow out comparatively clean wind from first air outlet 121.

Specifically, when the first air inlets 111a are two, and the two first air inlets 111a are respectively disposed on the two side plates 110, the first centrifugal fan 800 may be a single-side air suction first centrifugal fan 800, that is, the single-side air suction first centrifugal fan 800 has only one first air inlet side, where the single-side air suction first centrifugal fan 800 may be one, so that the first air inlet side faces any one of the first air inlets 111 a. Or the number of the first centrifugal fans 800 induced draft on one side may be two, the first air intake sides of the first centrifugal fans 800 induced draft on two sides respectively face the two first air inlets 111a, at this time, the number of the first purification modules 210 may also be two, and the two first purification modules 210 are respectively arranged corresponding to the two first air inlets 111a and respectively correspond to the first air intake sides of the first centrifugal fans 800 induced draft on each side.

Certainly, when the first air inlets 111a are two, and the two first air inlets 111a are respectively disposed on the two opposite side plates 110, the first centrifugal fan 800 may also be a double-side air suction first centrifugal fan 800, that is, the first centrifugal fan 800 has two first air inlet sides disposed oppositely, and at this time, only one first centrifugal fan 800 for double-side air suction needs to be disposed. The number of the first purification modules 210 may also be two, and the two sterilization modules are respectively disposed corresponding to the two first air inlets 111a and are respectively disposed on the two first air inlet sides of the first centrifugal fan 800 that induced drafts on the two sides.

It can be understood that the first purification module 210 needs to be powered on to operate, and in order to realize the power-on effect of the first purification module 210, the power-on module 220 is disposed on the first purification module 210. As shown in fig. 10, in order to facilitate replacement of the first purification module 210, the power connection module 220 may be disposed at a rear end of the first purification module 210, that is, the power connection module 220 is disposed at an end of the first purification module 210 away from the front panel 130, so that when the first purification module 210 is drawn out from the front and replaced, the influence of the process on the power connection module 220 is small.

In order to ensure better air outlet quality, please refer to fig. 1 to 3 in this embodiment, a formaldehyde removing module 400 is installed at the first air outlet 121.

Through installing in first air outlet 121 department and removing formaldehyde module 400, then disinfect the purification back through first purification module 210 in the upper air duct 101, still can realize getting rid of formaldehyde gas through removing formaldehyde module 400 to the air that further guarantees to blow off from this air purification device is clean air.

Of course, in other embodiments, the manganese mesh module can be replaced by a module having a formaldehyde removing function, such as activated carbon, in order to achieve the formaldehyde removing effect. In addition, it can be understood that the formaldehyde removing module 400 can also be placed on the air inlet side of the first centrifugal fan 800, that is, the outside air is blown out to the first air outlet 121 by the first centrifugal fan 800 after formaldehyde is removed by the formaldehyde removing module 400.

Further, as shown in fig. 9, in order to facilitate the external air to enter the lower air duct 102 and facilitate the air in the lower air duct 102 to flow out through the second air outlet 131, a second centrifugal fan 900 may also be disposed in the lower air duct 102, the second centrifugal fan 900 has a second air inlet side and a second air outlet side which are communicated with each other, the second air inlet side faces the second air inlet 111b, and the second air outlet side is communicated with the second air outlet 131.

By arranging the second centrifugal fan 900 in the lower air duct 102, the second air inlet side of the second centrifugal fan 900 faces the second air inlet 111b, and the second air outlet side of the second centrifugal fan 900 is communicated with the second air outlet 131, external air can be sucked in through the second air inlet 111b and blown out through the second air outlet 131 under the action of the second centrifugal fan 900. Specifically, when there is one second air inlet 111b, the second centrifugal fan 900 may be a second centrifugal fan 900 that performs single-side air suction, and the second centrifugal fan 900 that performs single-side air suction has only one second air inlet side facing the second air inlet 111b, so as to perform air suction from the second air inlet 111 b. When the second air inlet 111b is provided with two air inlets and respectively disposed on the two opposite side plates 110, the second centrifugal fan 900 may also be a second centrifugal fan 900 that sucks air from two sides, and at this time, the second centrifugal fan 900 has two second air inlet sides, and the two second air inlet sides respectively face the two air inlets 111 b.

The second air outlet 131 communicating with the lower air duct 102 is provided on the front panel 130, so that it can be ensured that the wind can be directly blown into the room when the lower air duct 102 is exhausted. It can be understood that, because the second air outlet 131 is communicated with the lower air duct 102, when the second air outlet 131 is opened on the front panel 130, the second air outlet 131 is at a lower position, and the air blown out from the second air outlet 131 cannot directly blow to a human face, thereby effectively protecting a user; moreover, when the second outlet 131 is disposed on the front panel 130, the air blown out from the second outlet 131 can directly sterilize the indoor air, thereby improving the sterilization effect. Of course, in other embodiments, the second air outlet 131 may also be disposed on other side panels 110.

In another embodiment, please refer to fig. 6 to 8, the second air outlet 131 can also be disposed on the top cover 120.

By arranging the second air outlet 131 in the top cover 120, the air passing through the lower air duct 102 can be discharged upwards, and the disinfectant released by the lower air duct 102 is prevented from being directly blown to the user. Specifically, the first air outlet 121 and the second air outlet 131 may be the same air outlet, so that more air outlets can be prevented from being formed in the top cover 120, the number of processes can be reduced, and the strength of the top cover 120 can be improved. Or the first air outlet 121 and the second air outlet 131 are different air outlets, and the two air outlets are arranged on the top cover 120 at intervals, so that the air blown out from the upper air duct 101 and the air blown out from the lower air duct 102 can be prevented from mixing with each other.
