[0002] Nowadays, more and more people have paid more attention to air quality. Therefore, purification devices have emerged in the market to improve the indoor environmental quality. The existing purification devices have relatively single functions and poor adaptability, that is, the automated detection and operation for indoor air purification are not perfect, and they cannot be used under different conditions, such as in spring, summer, autumn, smoking and other conditions. Under certain conditions, the purification devices may become useless. That is to say, the existing purification devices cannot purify all the pollutants in the room and cannot reach the purification standard of complete purification. After the purification device purifies one kind of pollutant, there may still be other serious pollutants in the room. Summary of the Invention

[0013] Optionally, the bent baffle is rotatably installed at the corresponding communication port around a rotation axis parallel to the axis of the multi-outlet centrifugal fan, or the bent baffle is movably installed at the corresponding communication port along a direction parallel to the axis of the multi-outlet centrifugal fan.

[0014] Optionally, each valve device is a wind valve, including a valve plate, and each valve plate is rotatably installed in the corresponding air supply duct.

[0015] Optionally, a fan inlet communicated with the air inlet is provided on the lower side of the multi-outlet centrifugal fan; a plurality of the air supply outlets and the air inlet located in the middle of the plurality of air supply outlets are provided on the lower surface of the housing.

[0016] Optionally, the multi-outlet centrifugal fan has a plurality of connecting air ducts communicating the volute of the multi-outlet centrifugal fan with the plurality of air outlets;

[0017] A horizontal track and an inclined track are provided in each connecting air duct, and the inclined track is installed at one end of the horizontal track close to the corresponding air supply outlet and can move up and down;

[0018] Each purification module is installed on the horizontal track, and the upper end of the inclined track contacts and abuts against the purification module to limit the corresponding purification module; the inclined track extends obliquely from its upper end in a direction away from the corresponding purification module to the lower end of the inclined track; and

[0019] The lower end of the inclined track moves downward out of the corresponding air supply outlet, and the upper end of the inclined track is connected downward to the horizontal track, so that the corresponding purification module moves out of the connecting air duct through the horizontal track and the inclined track, or the outer purification module moves to the corresponding horizontal track through the corresponding inclined track and the horizontal track.

[0020] Optionally, an air outlet grille is detachably installed at each air supply outlet.

[0021] Optionally, each air outlet grille includes:

[0022] An air outlet frame, in which a fixing frame is arranged.

It has strong purification pertinence and good purification effect, and can purify a variety of pollutants with one device, with a wide variety of purification types, and can achieve comprehensive purification, adapting to various single-pollutant scenarios and pollutant mixture scenarios; the purification modules are not arranged overlappingly, and only the corresponding purification module needs to be turned on to purify the pollutant, that is, it can be processed according to requirements and the purification means can be configured according to environmental adaptability, with high purification efficiency and energy saving; during the purification process, there will be no unnecessary purification modules working, reducing module waste, and there will be no increase in wind resistance caused by the working of unnecessary purification modules.

[0026] Furthermore, when there are multiple pollutants at the same time, preferably, the purification can be carried out in sequence according to the concentration of the pollutants; of course, multiple purification modules can also be turned on simultaneously for purification. Although each purification module cannot complete the purification of all pollutants, each purification module has high efficiency and can fully meet the purification requirements.

[0027] Furthermore, before this application, ordinary purification devices had to go through multiple purification means simultaneously during purification, regardless of whether the customer or the environment needed them. In this way, the energy consumption of the fan was large, and the purification device had a heavy burden and needed to be replaced frequently in its entirety. The air purification device of the present invention can replace each purification module separately, enabling the service life of each purification module to reach the longest, saving the replacement frequency and cost.

[0028] Furthermore, before this application, ordinary purification devices were all configured with different purification means to achieve the effect of purifying air through different means combinations. The inventors of this application found that the types of pollutants in different actual use environments are different, and by setting different purification devices at different outlets to match the user's needs, the energy consumption of the purification device can be reduced, and at the same time, the user's usage cost can be saved.

[0029] Moreover, the air purification device of the present invention can replace modules in a targeted manner, and even customize purification modules according to customer needs. Even more, the same type of purification module can be installed at multiple air outlets to adapt to a scenario where a certain pollutant is particularly severe, improving the applicable range of the air purification device, with strong adaptability and convenient use.

[0030] Furthermore, due to the special installation method of the purification module, the air purification device can have a simple structure, with the purification module being easy to disassemble and install, facilitating replacement and maintenance, and no additional replacement openings need to be set. The special structure of the air outlet grille can prevent the purified air from blowing at high speed towards a fixed point, and is superior to the dispersion of the purified air.

The purification module 50 is installed using the above structure, and the disassembly and assembly are convenient and fast.
