Abstract
The invention provides an air purifier with independent duel channel, which has separate first channel portion and second channel portion, wherein the first channel portion is used to filter particulate matters in the air and the second channel portion is used to purify the air. The invention mainly separates the channels and processes of the filtered air and the purified air, and more matches the selection of specific suction fan and intake fan so as to meet the different flow velocities required for air filtration and purification respectively, thereby achieving the optimal air filtration and purification effects, and improving the ineffective problem caused by the simultaneous filtration and purification of the air in the same channel of the existing air purifier.
Claims8
An air purifier with independent duel channel, mainly comprising:
- a first channel portion and a second portion;
- wherein the first channel portion includes
- a filtration channel that is provided with a suction end and an exhaust end,
- a suction fan that is arranged between the suction end and the exhaust end in the filtration channel, providing suction to suck air into the filtration channel from the suction end and send the air out from the exhaust end, wherein the suction fan is a swirl-flow fan,
- a filter mesh that is arranged near the suction fan towards the suction end side of the filtration channel;
- and
- wherein the second channel portion includes
- a purification channel that is provided with an inlet end and an outlet end,
- an intake fan that is arranged between the inlet end and the outlet end in the purification channel, providing suction to suck air from the inlet end into the purification channel and send the air out from the outlet end, wherein the intake fan is an axial-flow fan,
- an air purification module that is arranged in the inlet end of the purification channel;
- wherein the suction fan provided greater suction for the outside air to overcome the resistance of the filter mesh,
- wherein the intake fan provided less suction to prolong the residence time of the air in the purification channel.
