[0021] Among them, a filter cotton plate 401 is fixedly installed on the top of the top of the recoverer 4 close to the secondary filter channel 2. The inside of the filter cotton plate 401 is wrapped with a steel frame.

[0022] Among them, the top of the diversion channel 7 is a concave structure, and a through groove running through the middle of the diversion channel 7 is opened on both sides of the concave structure; a guide frame 701 is fixedly set in the middle of the diversion channel 7; the installation directions of the two groups of diversion channels 7 are opposite; the guide frames 701 are all bucket-shaped zoom structures, and a felt ring is fixedly set at the outer end of the zoom part; the output channel 8 is fixedly set outside the diversion channel 7 at the bottom of the secondary filter channel 2; the input channel 9 is fixedly set outside the diversion channel 7 at the bottom of the conveying channel 3.

[0023] Among them, a louver bar 801 is rotatably set in the middle of the opening of the output channel 8, and a control gear 802 is fixedly set at the bottom of the rotating shaft of the louver bar 801; a micro electric cylinder 803 is fixedly set at the bottom of the output channel 8, and a control rack 804 is fixedly set at the telescopic end of the micro electric cylinder 803, and the control rack 804 is engaged with the control gear 802.

[0024] Among them, an air intake filter cover 901 is fixedly installed inside the opening of the input channel 9; two sets of placement rollers 10 are rotatably installed at the positions of the diversion channel 7 located inside the output channel 8 and the input channel 9, and a filter cotton belt 11 is rotatably installed outside the placement rollers 10; the guide frame 701 is located on both sides of the inside of the filter cotton belt 11, and the felt ring outside the guide frame 701 fits the inner side of the filter cotton belt 11; the two sides of the guide frame 701 are connected to the through grooves on both sides of the diversion channel 7; a motor is set outside the input channel 9 to drive the filter cotton belt 11.

[0025] Among them, a silent pump 13 is connected to the lower part of the outside of the liquid tank 12, and a pipe is set at the output end of the silent pump 13 to connect to the docking plate 14. One end of the filter tube shaft 6 passing through the secondary filter channel 2 is rotated in the docking plate 14 in conjunction with the shaft seal.

[0026] A pipe is provided on the top of one side of the liquid tank 12 to connect with a ball valve 15 , and the top of the ball valve 15 is connected with an input hopper 16 ; when the ball valve 15 is closed for a long time or when not in use, volatilization can be reduced.

[0027] Open the ball valve 15 and pour alcohol into the input hopper 16; you can also adjust the disinfectant as needed; Centrifugal soaking step: start the drive motor 309 to drive the filter tube shaft 6 to rotate, thereby causing all components to rotate synchronously to generate centrifugal force; The silent pump 13 is started to continuously input alcohol into the filter tube shaft 6; the alcohol penetrates into the filter cotton ring 607 through the liquid outlet 601 and the sleeve hole 603. Under the action of centrifugal force, the alcohol moves outward, passes through the drainage hole 606 and splashes onto the ring cotton strip 101, soaking the ring cotton strip 101; the alcohol in the ring cotton strip 101 drips into the recovery device 4 under the influence of gravity; Air disinfection and output: When the filter tube shaft 6 rotates, the transmission gear 608 drives the two sets of driven gears 303 to rotate, and the driven gears 303 drive the transmission wheel 301 to rotate, causing the eccentric rod 302 to slide in the control frame 305, driving the control frame 305 to reciprocate up and down, and the piston plate 304 to move synchronously, adjusting the distance between the piston plate 304 and the sealing plate 306, producing a variable volume effect; Compared with the conventional technology of using fans to transport airflow, the variable volume conveying method is more stable. When the filter cotton ring 607 is soaked, resistance will be generated. It is not easy for the airflow to pass through when using fans, which will reduce the airflow. The variable volume conveying method can ensure that the airflow passes through the filter cotton ring 607 for disinfection and purification. In order to prevent the gas from passing through the gap between the filter sleeve 605 and the disinfection channel 1 and the annular cotton strip 101, a surrounding inclined strip flange is also provided on the outside of the filter sleeve 605. When the filter sleeve 605 rotates, it acts as a fan and generates a thrust in the opposite direction of the air intake, thereby ensuring that the gas can only continue to move through the filter cotton ring 607, and even some of the filtered air can be filtered again; The driving motor 309 and its transmission components, which are prone to noise generation, are installed outdoors, while the filter cotton ring 607 can also block the noise, play a sound insulation effect, and have little impact on the interior; The air passes through the air inlet filter cover 901, passes through the side of the filter cotton belt 11 in the input channel 9, passes through the guide frame 701 adjacent to the input channel 9, enters the conveying channel 3, and then enters the disinfection channel 1; During this process, the air passes through the filter cotton ring 607 and contacts the alcohol to complete the disinfection. It then passes through the secondary filter channel 2, the filter cotton plate 401 and the output channel 8, and is discharged through the side of the filter cotton belt 11 in the output channel 8. The filter cotton belt 11 intercepts the alcohol in the air and reduces the humidity. During this period, the filter cotton plate 401 intercepts the alcohol for the second time and recovers it into the recovery device 4 through diffusion and gravity. Wind direction adjustment: The micro electric cylinder 803 drives the control rack 804 to move, and the control rack 804 drives the control gear 802 to rotate, thereby adjusting the expansion angle of the louver 801 to achieve wind direction adjustment; Turning over: using the motor to drive the placement roller 10 to drive the filter cotton belt 11 to rotate continuously, changing the filter surface, and switching the position where the filter cotton belt 11 contacts the two sets of guide frames 701; Alcohol circulation and replenishment: Utilizing the volatile nature of alcohol and cooperating with the suction force generated by the guide frame 701 in the diversion channel 7 adjacent to the input channel 9, alcohol volatilization is accelerated, and the absorbed alcohol vapor enters the circulation, reducing consumption. At the same time, the air output by the other set of guide frames 701 passes through the dry filter cotton belt 11; The alcohol in the recovery device 4 flows back to the liquid tank 12. When the liquid level of the liquid tank 12 drops, the disinfectant is replenished in time to keep the equipment working continuously.

[0028] Example 2: Based on Example 1, the secondary filtration channel 2 and its associated components can be installed indoors, the delivery channel 3 and its associated components can be installed outdoors (or in a corridor, stairway, etc.), and the disinfection channel 1 can be penetrated through the wall; this allows fresh air to enter and isolates the noise generated by the drive motor 309 and its transmission components; The dimensions of the delivery channel 3 and the piston plate 304 can be customized and adjusted as needed to increase the delivery efficiency and the airflow; the indoor ventilation efficiency can also be improved by increasing the number of devices.

[0029] Example 3: Based on Example 1, electric heating wires can be added inside the output channel 8 and the input channel 9 to increase the temperature as needed to achieve temperature control, and the drying of the filter cotton belt 11 can also be accelerated; a humidity sensor is set in the input channel 9 to monitor the humidity. When the air humidity is too high, the speed of the silent pump 13 is reduced and the rotation speed of the filter tube shaft 6 is increased to reduce the output humidity.

[0030] Specific usage and function of this embodiment: In the present invention, when in use, the device is installed in a suitable position; Open the ball valve 15 and pour disinfectant into the input hopper 16 in advance, taking alcohol as an example; Start the drive motor 309 to drive the filter tube shaft 6 to rotate, and the filter tube shaft 6 drives all components to rotate synchronously, generating centrifugal force; Start the silent pump 13 to continuously input alcohol into the filter tube shaft 6. The alcohol penetrates the liquid outlet 601 and the sleeve hole 603 into the filter cotton ring 607, distributing the alcohol in the filter cotton ring 607. Under the influence of centrifugal force, the alcohol continuously moves outward, penetrates the drainage hole 606 and splashes into the annular cotton strip 101, soaking the annular cotton strip 101. The alcohol in the annular cotton strip 101 continuously drops under the influence of gravity and drips into the recovery device 4. When the filter tube shaft 6 rotates, the transmission gear 608 drives the two sets of driven gears 303 to rotate, and the driven gear 303 drives the transmission wheel 301 to rotate, so that the eccentric rod 302 slides in the control frame 305, driving the control frame 305 to move up and down, and the piston plate 304 moves synchronously, repeatedly adjusting the distance between the piston plate 304 and the sealing plate 306, cooperating with the one-way valve 307 to produce a variable volume effect, and the air passes through the air intake filter cover 901 and the side of the filter cotton belt 11 in the input channel 9 and the guide frame 701 into the conveying channel 3, and passes through the conveying channel 3 into the interior of the disinfection channel 1. During this period, the air passes through the filter cotton ring 607 and contacts the alcohol for disinfection, and then passes through the secondary filter channel 2, the filter cotton plate 401 and the output channel 8, and is discharged through the side of the filter cotton belt 11 in the output channel 8. The filter cotton belt 11 is used to intercept the alcohol in the air and reduce the output air humidity; the filter cotton plate 401 can intercept the alcohol in the air for a second time and recycle it into the recycler 4; The micro electric cylinder 803 drives the control rack 804 to move, and the control rack 804 drives the control gear 802 to rotate, which can adjust the expansion angle of the louver 801 and adjust the wind direction; The motor drives the placement roller 10 to drive the filter cotton belt 11 to rotate continuously, so that the filter surface can be replaced and the position of the filter cotton belt 11 contacting the two sets of guide frames 701 can be continuously switched; Alcohol is easy to volatilize, and the guide frame 701 in the diversion channel 7 adjacent to the input channel 9 continuously generates suction, which can make the alcohol evaporate faster. The absorbed alcohol vapor can also enter the circulation, reducing consumption, and can also allow the air output by the other set of guide frames 701 to pass through the dry filter cotton belt 11; The alcohol in the recoverer 4 can flow back into the liquid tank 12; after the liquid level of the liquid tank 12 drops, it can be replenished in time to keep working.
