an air purifier

technical field

The utility model relates to the field of air purification, in particular to an air purifier.

Background technique

Smog is the result of the interaction between specific climatic conditions and human activities. The economic and social activities of high-density population will inevitably emit a large amount of fine particles (such as PM 2.5, PM10). Affected by weather and other factors, it is very easy to have large-scale smog.

Facing the crazy and raging smog weather, people's awareness of the hazards of smog is also increasing. In severe smog seasons, most people choose to wear masks outdoors to prevent haze. Indoors, people generally use air purifiers to filter fine particles in the air to prevent haze. However, this indoor haze prevention method has the following disadvantages: question:

1. Most of the existing air purifiers use fans and filters to purify the air. However, the filter area is small, and the air outlets of the air purifiers are less, so that the wind mostly flows in certain directions. However, it is inevitable that there will be dead angles when the wind utilizes the flow of air. Therefore, most of these air purifiers can only produce a certain purification effect near the place where the air purifier is placed, and the filtration efficiency is low. It takes a long time to fully filter the indoor air. It is difficult to produce an effect on the purification of the entire indoor air;

2. Most of the existing air purifiers use the indoor circulation filter mode, that is, when using this kind of air purifier, the windows are generally closed, so when using this kind of air purifier, it cannot provide fresh air for the room, but the indoor air repeatedly If the internal circulation is not supplied with outdoor fresh air, a large number of bacteria will grow. In addition, people will produce a large amount of carbon dioxide and other waste gases indoors, resulting in excessive carbon dioxide, which is not conducive to human health.

Utility model content

The purpose of the utility model is: when the air purifier is used indoors to filter the fine particles in the air to prevent haze, the existing air purifier has less air outlets and a smaller filter area, resulting in a better purification effect on the entire indoor air. Poor, and the problem of being unable to provide fresh air for the room when in use, the utility model provides an air purifier, the air purifier is provided with multi-faceted air outlets, so that the wind can flow from the surroundings of the air purifier to multiple directions, Therefore, the whole indoor air can be purified better, and at the same time, when the air purifier is used, fresh air can be provided for the indoor environment, which is beneficial to human health.

In order to achieve the above object, the technical solution adopted by the utility model is:
