[0039] A portable air purifier in this embodiment, by setting a filter cylinder 4 with filter holes 5 at the bottom of the bottom cylinder 1, can effectively filter out larger floating objects, and at the same time avoid the filter holes 5 being completely blocked, ensuring the initial cleaning of the air entering the purifier. The water source arranged inside the water storage bellows makes full use of the strong adsorption and solubility of water molecules to tiny particles in the air. When the air flows through the bellows, it can effectively capture and remove particulate dust in the air, including harmful substances such as fine PM2.5, thereby providing a fresher and healthier air environment.

The built-in heating wire 10 and temperature sensor 11 can adjust the air flow temperature, especially in cold seasons, effectively reducing the discomfort of users caused by inhaling cold air and improving the comfort and convenience of use.

[0040] The working principle of the above embodiments is as follows: When the device is started, external air enters through the intake pipe 3 at the bottom end of the bottom cylinder 1. First, it passes through the filter cylinder 4. The filter holes 5 on the filter cylinder 4 effectively block and filter out larger floating objects and particulate matters, ensuring that the air entering the purifier is initially clean. The filtered air is drawn into the bottom cylinder 1 by the pump body 6 and passes upward through the corrugated water storage cylinder 12. The water source in the water storage cylinder utilizes the strong adsorption and solubility of water molecules to minute particles to effectively capture and remove particulate dust in the air, such as PM2.5, etc. The purified air enters the top cylinder 2 and is heated by the heating wire 10. The temperature sensor 11 monitors the air flow temperature in real time and adjusts the power of the heating wire 10 according to the preset value to ensure that the output air flow is warm and comfortable, especially suitable for use in cold seasons. The air that has been purified and heated passes through the connecting pipe 9, the hose 16, and the face mask 17, and is finally delivered to the user. The face mask 17 is equipped with a wearing rope 18, which is convenient for the user to wear and enjoy fresh and warm air.
