Air outlet or air outlet grille.

Preferably, the air filter set includes a dust-proof filter cotton layer and an activated carbon filter.

Activated carbon filters poisonous gas or vapor through adsorption or chemical reaction. There are many micropores in the internal structure of activated carbon, which can form a large specific surface area. These micropores can absorb poisonous vapor and poisonous gas molecules of different molecular sizes into it without escape. The activated carbon filter can remove most of the odor substances, fine particles, harmful gases, formaldehyde, benzene and ammonia in the air.

Preferably, the purifier further includes an air detection device and an air quality warning light arranged on the housing.

The air detection device is used to detect the PM2.5 content in the air around the portable air purifier. When the air quality index AQI exceeds the standard, the air quality warning light on the outer casing will light up to give an alarm.

Preferably, a negative ion generator is provided below the fan.

The negative ion generator releases a large number of electrons to the purified air, combines with oxygen molecules in the air to generate a large number of negative ions mixed into the purified air, and negative ions can increase the oxygen content in the blood and promote metabolism.

Preferably, the power supply system includes batteries.

Preferably, a USB charging jack is provided on the base.

Preferably, the battery is located in the inner cavity of the base, and a fan motor driving circuit is also arranged in the inner cavity of the base. The charging circuit, the fan motor drive circuit and the battery are located at the base. It not only plays the role of counterweight but also places the working circuit, which saves space, makes the volume of the air purifier as small as possible, and is easy to carry.

Compared with the traditional air purifier, the utility model mainly has the following characteristics:

1. Small size, easy to carry, can be used in many environments with small spaces, such as in the car, desk, bedside, desk, bathroom, etc.;

2. It can be used with masks with various air filtration functions and filter screens of suitable sizes. The purification function can be flexibly changed with the functions of the masks. It is also convenient for users to replace the filter screen and reuse the mask, reducing the cost of use;

3. It has a charging function, can be used without power input, and is easy to move;

4. The charging line adopts the universal mobile phone charging line, which is convenient for users to use in the car and indoors.
