，該導流口124的孔徑d為11.66㎜，值得注意的是，於本實施例的其他變化態樣中，該抽氣模組5提供的風量及該導流口124的孔徑d也可為其他數值，不當以此為限。 When the air flows upward from the air outlet 123 through the guide port 124 , the flow velocity will increase due to Bernoulli's principle, thereby increasing the height of the upward spray of the air. In this embodiment, the bamboo charcoal filter element air purifier is an air purifier suitable for desktop use, the air outlet diameter of the air extraction module 5 is 60 mm, the horizontal cross-sectional area is 300 mm ² , and the volume flow rate is 4.73 mm. For the air volume of CFM (Cubic Feet per Minute), the maximum height reached by the air discharged through the guide port 124 is 250 mm relative to the distance from the guide port 124, and the exhaust speed through the guide port 124 is 2.2136

, the aperture d of the guide port 124 is 11.66 mm. It is worth noting that in other variations of this embodiment, the air volume provided by the air extraction module 5 and the aperture d of the guide port 124 can also be Other values should not be limited by this.

It is worth noting that the dust collecting hopper 31 of the dust collecting module 3 can also collect part of the dust dropped from the filter module 2 to keep the interior of the chamber 13 clean.

Through the above description, the effects and advantages of the present invention are summarized as follows:

1. The low temperature bamboo charcoal layer 23 is used as the front-stage filter layer, and the high-temperature bamboo charcoal layer 25 is used as the rear-stage filter layer, which can efficiently filter the dust particles of different diameters, and the bamboo charcoal has the function of adsorbing peculiar smells, and further achieves the removal of smelly effect. In addition, the low-temperature bamboo charcoal sheets 231 and the high-temperature bamboo charcoal sheets 251 can be reused after being cleaned, heated and dried, and there is no need to frequently replace new filter materials, which is more convenient and environmentally friendly in maintenance.

2. The dust collecting module 3 is a cyclone dust collector. The dust collecting hopper 31 prevents the air from entering the chamber 13 from the air inlets 113 and cannot directly enter the filter chamber 26 through the lower screen plate 211. Enter the dust collecting space 38 through the air inlet 351 of the air inlet pipe 35, and enter the filter chamber 26 through the lower screen plate 211 after screening out the larger diameter dust particles, so that the large dust particles can be prevented from blocking the low-temperature bamboo charcoal. layer 23 , thereby improving the filtering efficiency of the filtering module 2 .

3. The truncated cone-shaped guide wall 122 increases the flow velocity of the air when passing through the guide port 124, which can increase the maximum height that the air can reach when discharged upward, so that when the present invention is placed on a table for use, the user You can feel the clean air directly on your face.

To sum up, the bamboo charcoal filter element air purifier of the present invention can indeed achieve the purpose of the present invention.
