DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

[0016] Please refer to FIG. 1 and FIG. 2 for schematic diagrams illustrating sectional and exploded views of the air purifier with independent dual channel of the present invention. As shown in the diagrams, the air purifier mainly comprises a first channel portion 100 and a second channel portion 200, which are accommodated in a shell portion 300. The first channel portion 100 includes a filtration channel 110, a suction fan 120 and a filter mesh 130. The suction fan 120 is arranged between a suction end 111 and an exhaust end 112 in the filtration channel 110 to provide suction for passing the external air through the filter mesh 130 located near the suction fan 120 towards the suction end 111 of the filtration channel 110, and then the air of the filtered particulate matters is sucked into the filtration channel 110 and discharged by the exhaust end 112. The first channel portion 100 further includes a particulate matter detection module 140 adjacent to the exhaust end 112 of the filtration channel 110 for detecting the particulate matter concentration in the filtration channel 110. The second channel portion 200 includes a purification channel 210, an intake fan 220 and an air purification module 230. The intake fan 220 is arranged between an inlet end 211 and an outlet end 212 in the purification channel 210 to provide suction for sucking air into the purification channel 210, and the purified air is discharged by the outlet end 212 via the air purification module 230 arranged in the inlet end 211.

[0017] Further referring to FIG. 2, the shell portion 300 comprises a front cover 310, a rear cover 320, a left cover 330, a right cover 340, an upper cover 350 and a lower cover 360; wherein the front cover 310 is connected with one end of the purification channel 210, and an inlet port 311 is arranged on the front cover 310 corresponding to the inlet end 211 of the purification channel 210; wherein the rear cover 320 is connected with the other end of the purification channel 210, and an outlet port 321 is arranged on the rear cover 320 corresponding to the outlet end 212 of the purification channel 210; wherein the left cover 330 is arranged on one side of both the filtration channel 110 and the purification channel 210; wherein the right cover 340 is arranged on the other side of both the filtration channel 110 and the purification channel 210, and a suction port 341 is arranged on the right cover 340 corresponding to the suction end 111 of the filtration channel 110; wherein the upper cover 350 is connected with one end of the filtration channel 110, and an exhaust port 351 is arranged on the upper cover 350 corresponding to at the exhaust end 112 of the filtration channel 110; and wherein the lower cover 360 is arranged at the bottom of the purification channel 210. The right cover 340 further includes a filter mesh fixture 342, and the filter mesh 130 is clamped between the filter mesh fixture 342 and the suction port 341 of the right cover 340.

[0018] Please refer to FIG. 3 for a schematic diagram illustrating sectional and exploded view of the first channel portion 100 of the present invention and FIG. 2. When the suction fan 120 sucks air into the filtration channel 110 from the outside via the filter mesh 130, the suction port 341 and the suction end 111, the filter mesh 130 can filter particulate matters in the air, wherein the suction fan 120 adopts a swirl-flow fan to provide greater suction for the outside air to overcome the resistance of the filter mesh 130, and through a plurality of swirl blades 121 arranged around the suction fan 120 achieve the effect of making the filtered air evenly enter the filtration channel 110. The bore of the filtration channel 110 is gradually expanded from the suction end 111 to the exhaust end 112, which can further slowdown the filtered air toward the exhaust end 112. Thus, the air purifier of the invention achieves the air circulation effect of full filtration and uniform diffusion.

[0019] Please refer to FIG. 4 for a schematic diagram illustrating sectional and exploded view of the second channel portion 200 of the present invention and FIG. 2. The intake fan 220 arranged between the inlet end 211 and the outlet end 212 can be an axial-flow fan, and the air purification module 230 is arranged in the inlet end 211 within the purification channel 210, wherein the bore of the purification channel 210 is gradually expanded from the inlet end 211 to the outlet end 212. When the intake fan 220 sucks outside air from the inlet end 211, the air in the purification channel 210 is purified by the air purification module 230, wherein of the intake fan 220 employs the weaker suction provided by the axial-flow fan to prolong the residence time of the air in the purification channel 210, thereby enabling the air to be fully purified via the air purification module 230, and wherein the air purification module 230 is one or combination of an ozone generator, a photocatalyst sterilizer and an anion generator. Thus, the air purifier of the invention achieves the air circulation effect of full purification and uniform diffusion.

[0020] Please refer to FIG. 5 for a schematic diagram illustrating perspective view of the air purifier with independent dual channel of the present invention and aforesaid FIG. 1 to FIG. 4. By the suction fan 120 arranged in the first channel portion 100, the outside air is sequentially passed through the suction port 341 of the right cover 340, and the particulate matters in the air are filtered through the filter mesh 130, and the filtered air is sucked into the filtration channel 110 through the suction end 111, the filtered air is then sent out through the exhaust end 112 and the exhaust port 351 on the upper cover 350. By the intake fan 220 arranged in the second channel portion 200, the outside air is sequentially passed through the inlet port 311 of the front cover 310, sucked into the purification channel 210 through the inlet end 211 and purified by the air purification module 230, the purified air is then sent out through the outlet end 212 and the outlet port 321 on the rear cover 320.

[0021] The present invention is based on the fact that the existing air purifier is to complete two processes of air filtration and air purification by air passing through a single channel. However, in practice, the same air velocity in the single channel cannot simultaneously meet the processing requirements of the above two different functions, thereby leading to the problem of either unable to cope with one without letting go of the other, or the processing effects of both are not complete. In order to solve the aforesaid problems of the existing technology, an air purifier with independent dual channel is proposed, which not only separates the channels for processing air filtration and air purification, but also more matches the selection of suction fan and intake fan according to their specific air flow speed requirements, so as to deal with the filtration and purification processes independently. Thus, the overall performance of the air purifier with independent dual channel of the invention can be significantly improved through optimal air filtration and air purification effects.

Accordingly, the appended claims are intended to cover all embodiments which do not depart from the spirit and scope of the invention.
