Description

an air purifier

technical field

The utility model relates to the technical field of air purifiers, in particular to an air purifier capable of circulating and purifying the entire indoor air.

Background technique

Air purifiers, also known as "air cleaners", air fresheners, and purifiers, refer to the devices that can absorb, decompose or transform various air pollutants (generally including PM2.5, dust, pollen, odor, formaldehyde and other decoration pollution) , bacteria, allergens, etc.), products that effectively improve air cleanliness are mainly divided into household, commercial, industrial, and building.

There are many different technologies and media in an air purifier that enable it to provide clean and safe air to the user. Commonly used air purification technologies include: adsorption technology, negative (positive) ion technology, catalytic technology, photocatalyst technology, superstructure photomineralization technology, HEPA high-efficiency filtration technology, electrostatic dust collection technology, etc.; material technologies mainly include: photocatalyst, activated carbon, Extremely carbon core filter technology, synthetic fibers, HEAP high-efficiency materials, negative ion generators, etc. Most of the existing air purifiers are composite, that is, multiple purification technologies and material media are used at the same time.

In the prior art, the air purifiers generally installed in the hall directly purify the outdoor air and discharge it indoors to replace the indoor air, keep the indoor air pure, improve people's breathing freshness, and ensure people's However, this kind of air purifier has a large workload of purification and needs to constantly purify the external air, which is easy to damage the internal parts of the air purifier, so people also set the air intake end of the air purifier Indoors, after the indoor air is purified, it is directly discharged into the room, so that the purification workload of the air purifier is greatly reduced, but due to the unreasonable design and structure of the air purifier, the air inlet and outlet are not very good. The indoor circulation can only purify the air in a certain area of the room, so it is necessary to install multiple air purifiers indoors, resulting in a waste of a lot of resources and costs.

Utility model content

In view of this, it is necessary to provide an air purifier which has a simple structure and can effectively circulate and purify the air in the entire indoor area.

The utility model is achieved in this way, an air purifier is installed on the indoor ceiling, including an outer casing, a fan and a purifier, and also includes a shroud, a return fan blade and an outlet fan blade, and the outer casing is installed on the On the indoor ceiling, the outer shell is open on one side close to the indoor, and the other surfaces of the outer shell are sealed with each other. The axes are coincident, the shroud is cylindrical, and the shroud is installed on the fan. The air cavity communicates with the cavity in the shroud through the fan, the purifier is installed in the shroud, the end of the shroud far away from the fan is an air inlet, and the return fan blade is installed at the air inlet, and It is fixed on the shroud, and the outlet fan blade is installed at the air outlet cavity and fixed on the outer edge of the shroud.

Further, an arc-shaped air deflector is provided at the corner of the bottom of the outer shell away from the opening.

Further, the blade guiding directions of the return fan blades and the outlet fan blades can be adjusted.

The advantage of the air purifier provided by the utility model is that the structure of the utility model is simple and reasonable. , when in use, install the air purifier on the indoor ceiling, turn on the fan, and through the negative pressure, the indoor air enters from the return fan blade at the air inlet, and is purified by the purifier and sent to the air outlet cavity, and then The purified air enters the room from the outlet fan blades around to form an indoor circulation air purification circuit. Through the effect of the air outlet around the center and the air inlet in the center, the air inlet and outlet are adjusted through the return fan blades and the outlet fan blades. The direction can make the whole indoor air circulate and purify, it will not only purify the air in a small area, improve the purification efficiency, do not need to add multiple purifiers, and save costs and resources.

Detailed ways

In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model, and are not intended to limit the utility model.

Please refer to Figure 1 and Figure 2 together, wherein Figure 1 is a schematic structural view of an air cleaner of the present invention;

Described a kind of air purifier, is installed on the ceiling 10 on indoor, comprises outer casing 20, blower fan 30 and purifier 40, also comprises shroud 50, returns fan blade 60 and goes out fan blade 70, and described outer casing 20 Installed on the indoor ceiling 10, the outer casing 20 is open on one side close to the indoor, and the other surfaces of the outer casing 20 are sealed to each other. The central axis of the surrounding plate 50 coincides with the central axis of the outer shell 20, and the surrounding plate 50 is cylindrical, and the surrounding plate 50 is installed on the fan 30. An annular air outlet chamber a is formed between the outer casing 20, and the air outlet chamber a communicates with the cavity in the enclosure 50 through the fan 30, the purifier 40 is installed in the enclosure 50, and the enclosure The end of the fan 50 away from the fan 30 is the air inlet b, the return fan blade 60 is installed at the air inlet b, and is fixed on the enclosure 50, and the outlet fan blade 70 is installed at the air outlet cavity a, and fixed at the outer edge of the enclosure 50 .

The bottom corner of the outer casing 20 away from the opening is provided with an arc-shaped wind deflector 21 to reduce the resistance of the purified air in the air outlet chamber a.
