The above-described process is shown in fig. 10 and 11.
In this embodiment, in order to prevent magnetic interference, the C-shaped limiting member 6 is made of an aluminum alloy.
The positive and negative ion generator 16 is installed in the inner cavity 90 of the chassis of the present embodiment, and the specific working principle is shown in fig. 16 and 17.
The working principle and working process of the device are described in detail as follows:
as in fig. 3 and 6; when the mechanism is in an idle state: the electromagnet 8 is in a non-energized state, the isosceles surfaces of any two adjacent activated carbon air filtration isosceles trapezoid boxes 1 on the closed-loop disc-shaped filter box combination 74 are mutually attached, and a plurality of gas leading-out holes 32 on each activated carbon air filtration isosceles trapezoid box 1 and a plurality of gas leading-in holes 33 on each activated carbon air filtration isosceles trapezoid box 1 are blocked by the isosceles surfaces of the adjacent activated carbon air filtration isosceles trapezoid boxes 1; thereby, the activated carbon filter bin 31 in all the activated carbon air filter isosceles trapezoid boxes 1 is in a blocking state, and the activated carbon in the activated carbon filter bin 31 still adsorbs macromolecular particles in the environmental gas in an idle state, so that the activated carbon is prevented from being consumed.
The preparation is as follows: the stepping motor is controlled to enable the closed-loop disc-shaped filter box combination 74 to synchronously and slowly rotate along with the annular framework 23 and the rotary drum 24 as a whole until any one permanent magnet column 10 on the closed-loop disc-shaped filter box combination 74 corresponds to the iron core 9 of the electromagnet 8 in the same axial center; the attraction force between the permanent magnet post 10 and the non-energized core 9 is not sufficient to overcome the pull-back force of the pull-back spring 3, so that the permanent magnet post 10 corresponding to the core 9 does not move closer to the core 9 of the electromagnet 8.
The air filtering method comprises the following steps: at this time, the electromagnet 8 is started, after the electromagnet 8 is electrified, the iron core 9 magnetically attracts the permanent magnet column 10 corresponding to the axial center, the activated carbon air filtration isosceles trapezoid box 1 connected to the magnetically attracted permanent magnet column 10 overcomes the pull-back force of the pull-back spring 3 to move away from the rotary cylinder 24 along the radial direction until the permanent magnet column 10 coaxially contacts the iron core 9, at this time, the limit protrusion 21 on the narrow bottom surface 51 of the activated carbon air filtration isosceles trapezoid box 1 breaks away from the limit concave hole 22, at the same time, two gaps 40 are formed between the activated carbon air filtration isosceles trapezoid box 1 moving away from the rotary cylinder 24 and the left and right adjacent activated carbon air filtration isosceles trapezoid boxes 1, at this time, the annular bin 2 and the inner cavity 90 of the case are mutually communicated through the two gaps 40, as shown in fig. 8 and 9; the two gaps 40 are respectively a left gap 40.1 and a right gap 40.2; when the iron core 9 is magnetically attracted to the permanent magnet post 10 corresponding to the coaxial center, the C-shaped limiting piece 6 is semi-surrounded on the left side of the permanent magnet post 10, so that the permanent magnet post 10 is prevented from moving leftwards.
At this time, on the basis of the magnetic attraction of the iron core 9 to the corresponding permanent magnet column 10, the whole closed-loop disc-shaped filter box combination 74 is controlled to slowly rotate anticlockwise along the axis, at this time, the permanent magnet column 10 magnetically attracted by the iron core 9 cannot follow the whole closed-loop disc-shaped filter box combination 74 under the limit of the C-shaped limiting piece 6, so that the upper end position of the activated carbon air filter isosceles trapezoid box 1 far away from the rotary drum 24 is unchanged, the lower end is deflected leftwards, the lower end of the left gap 40.1 is gradually narrowed, and the upper end of the right gap 40.2 is gradually narrowed; until the lower end of the left slit 40.1 is gradually narrowed to be closed, and the upper end of the right slit 40.2 is gradually narrowed to be closed, the closed position of the lower end of the left slit 40.1 at this time is denoted as a first closed end 4, and the closed position of the upper end of the right slit 40.2 at this time is denoted as a second closed end 5; the gas leading-in holes 33 of the activated carbon air filtration isosceles trapezoid box 1 which is far away from the rotary drum 24 are communicated with the annular bin 2 through the lower end of the right slit 40.2, and the gas leading-out holes 32 of the activated carbon air filtration isosceles trapezoid box 1 which is far away from the rotary drum 24 are communicated with the inner cavity 90 of the machine box above the right slit 40.2; the above-described process is shown in fig. 10 and 11.
Then, starting a blower 19, wherein the blower 19 sends air to be filtered outside to an air inlet bin 027 to form positive pressure, then the air in the air inlet bin 027 enters an annular bin 2 under the action of air pressure to form positive pressure in the annular bin 2, and then the air in the annular bin 2 is continuously led into an activated carbon filter bin 31 from an air inlet hole 33 of an activated carbon air filter isosceles trapezoid box 1 far away from a rotary drum 24 through a right gap 40.2, and the air entering the activated carbon filter bin 31 is led out into a case cavity 90 from a plurality of air outlet holes 32 after being adsorbed and filtered by activated carbon in the activated carbon filter bin 31; finally, the filtered air in the inner cavity 90 of the case overflows through the two purified air overflows 20 and returns to the outside, thereby forming the function of air circulation filtration.
In the gas circulation filtering process, only the activated carbon of the filter bin 31 in the activated carbon air filtering isosceles trapezoid box 1 which moves away from the rotary drum 24 participates in the filtering process, and the activated carbon of the filter bin 31 in all other activated carbon air filtering isosceles trapezoid boxes 1 does not participate in adsorption and filtration in the gas circulation filtering process, so that the activated carbon is in a brand new state to be used.
The adsorption capacity of the activated carbon in the isosceles trapezoid box 1 for air filtration of the activated carbon which has been moved away from the rotary drum 24 gradually weakens with the lapse of time, and eventually the capacity of the activated carbon particles with the lapse of time has failed to meet the requirement for adsorption of odor; it is therefore necessary to transform an activated carbon air filtration isosceles trapezoid box 1 that has been moved away from rotary drum 24 into a new one; the specific process is as follows:
the replacement method comprises the following steps: firstly, the electromagnet 8 is powered off, and the activated carbon air filtration isosceles trapezoid box 1 which moves away from the rotary cylinder 24 and has the internal activated carbon consumed returns to the initial idle state under the action of the pull-back force of the pull-back spring 3; then, by controlling a stepping motor, the closed-loop disc-shaped filter box combination 74 integrally rotates slowly along with the annular framework 23 and the rotary drum 24 synchronously until the other permanent magnet column 10 on the closed-loop disc-shaped filter box combination 74 coaxially corresponds to the iron core 9 of the electromagnet 8; at this time, an activated carbon air filtration isosceles trapezoid box 1 connected with an iron core 9 concentric with the electromagnet 8 does not participate in the adsorption process before, and is an activated carbon air filtration isosceles trapezoid box 1 with brand new activated carbon inside; at this point the replacement process has been completed and the "air filtration method" is repeated during the next use: and the high-efficiency adsorption effect under the delivery state can be obtained again.
With reference to the above law, as long as the isosceles trapezoid box 1 for filtering the activated carbon air is consumed, the new isosceles trapezoid box 1 for filtering the activated carbon air can be replaced by repeating the replacement method until all isosceles trapezoid boxes 1 for filtering the activated carbon air are consumed, thereby the service life of the activated carbon of the device is prolonged to the maximum extent while the adsorption capacity is ensured.
The foregoing is only a preferred embodiment of the invention, it being noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the present invention, and such modifications and adaptations are intended to be comprehended within the scope of the invention.
