[0049] A material guide port 602 is provided on the tank body 201 at a position corresponding to the guide filter screen 6 , and a storage box 603 is fixedly installed on the outer side of the material guide port 602 .

[0050] Specifically, the second rotating assembly 8 includes a positioning seat 801, a rotating ring 802 and a fixing ring 804. The positioning seat 801 is fixedly connected to the inside of the vent 701. The fixing ring 804 is arranged below the vent 701. An upper toothed ring 805 is arranged at the bottom of the fixing ring 804. The rotating ring 802 is arranged below the fixing ring 804. A lower toothed ring 803 is arranged at the top of the rotating ring 802. The lower toothed ring 803 corresponds to the upper toothed ring 805. A rotating ring 802 is arranged in the middle. The impeller 8021 has a slot 8022 in the middle thereof, the bottom end of the lower rotating rod 5012 passes through the positioning seat 801 and is located inside the slot 8022, an electromagnetic latch is provided inside the slot 8022, and in the process of the second rotating assembly 8 driving the upper rotating rod 5011 and the lower rotating rod 5012 to rotate, the lower gear ring 803 cooperates with the upper gear ring 805 to make the rotating ring 802 drive the guide filter 6 to move up and down through the lower rotating rod 5012.

[0051] Among them, a spring 50131 is provided at the top of the limiting groove 5013, and the bottom of the spring 50131 is fixedly connected to the top of the lower rotating rod 5012. The spring 50131 at the top of the lower rotating rod 5012 is used to maintain an upward pulling force on the rotating impeller 8021, so that the lower gear ring 803 can remain close to the upper gear ring 805.

[0052] A rotating groove 806 is provided on the outer side of the bottom of the vent hole 701, and a limiting ring 807 corresponding to the rotating groove 806 is fixedly connected to the top of the fixed ring 804. An electromagnetic lock is provided inside the rotating groove 806, and the electromagnetic lock is used to lock the limiting ring 807. After the electromagnetic lock locks the limiting ring 807, the position of the fixing ring 804 is locked and fixed at the same time.

[0053] The rotating ring 802 is fixedly connected to the fine filter 9 via the connecting strip 808 , and the outer side of the fine filter 9 is in contact with and fits against the inner wall of the tank body 201 .

[0054] When the device is in use, the fan 3 is started, and the suction force generated by the fan 3 allows the external gas to continuously enter the interior of the filter tank 2 through the air inlet pipe 202, and the cooling plate 402 is driven to rotate when the gas passes through the impeller ring 20412. A humidity sensor is provided inside the first chamber 2011, and a humidity threshold is preset in the humidity sensor. When the humidity in the first chamber 2011 reaches the threshold, the semiconductor refrigeration plate switch in the condensation tank 401 is actively turned on, and the semiconductor refrigeration plate quickly cools down the condensation tank 401. The cooling plate 402 is cooled synchronously with the temperature of the condensation tank 401. During the rotation of the cooling plate 402, the gas in the first chamber 2011 is condensed and dried, and at the same time, the water guide plate 4021 is used to guide the condensed water on the cooling plate 402 so that the condensed water enters the water storage tank 403 for storage.

[0055] The gas condensed and dried in the first chamber 2011 enters the second chamber 2012 through the connecting pipe 20111. At this time, the electromagnetic latch inside the slot 8022 is locked and fixed with the bottom end of the lower rotating rod 5012, and the electromagnetic lock in the rotating slot 806 disconnects the lock on the limit ring 807. The gas after passing through the coarse filter 502 and the guide filter 6 passes through the rotating impeller 8021, causing the rotating impeller 8021 to rotate. The locking of the electromagnetic latch in the slot 8022 causes the rotating ring 802 to be locked with the fixed ring. The distance between 804 remains unchanged, so that the fixed ring 804 and the rotating ring 802 rotate synchronously, reducing the operating noise when the gas passes through the rotating impeller 8021, and the rotating impeller 8021 is used to drive the rotating column 501 and the coarse-effect filter 502 to rotate, so that larger impurities in the gas passing through the gap between two adjacent coarse-effect filters 502 are intercepted on the coarse-effect filter 502, and the rotating column 501 and the coarse-effect filter 502 in the continuous rotation process make the impurities evenly adhere to multiple coarse-effect filters 502.

[0056] During the continuous suction process of the fan 3, the gas passing through the rotating impeller 8021 is further filtered through the fine filter 9, and then the bacteria in the gas are killed by the sterilization lamp 10, completing the filtration and purification of the air. Finally, the filtered and purified gas is discharged from the tank body 201 and the shell 1 through the outlet pipe 203.

[0057] Furthermore, according to the needs of use, the electromagnetic lock in the rotating groove 806 is opened periodically to lock the limit ring 807, so that the fixed ring 804 remains fixed, and at the same time, the electromagnetic latch in the slot 8022 keeps the bottom end of the lower rotating rod 5012 locked and fixed, so that the rotating ring 802 rotates alone when the gas passes through the rotating impeller 8021, and as the lower toothed ring 803 slides in and out between the two adjacent upper toothed rings 805, the rotating ring 802 repeatedly approaches and moves away from the fixed ring 804, and the fine filter 9 is repeatedly vibrated up and down through the force transmission of the connecting strip 808, and the vibration of the fine filter 9 is used to make fine particle impurities escape from the filter holes of the fine filter 9, and the longitudinal section of the fine filter 9 is set to a trapezoidal structure, and the inclined surface of the fine filter 9 is used to make the fine particle impurities approach the outside, and the fine particle impurities can be collected by setting a storage groove on the outside of the fine filter 9.

[0058] Embodiment 2

[0059] See also Figure 1-6 As shown, in actual use, too much dust and impurities are easily accumulated on the coarse filter 502. The difficulty in cleaning the dust and impurities will affect the filtering effect of the coarse filter 502 and further affect the air purification quality of the equipment. The following embodiments are proposed to solve the above problems:

[0060] The condensed water in the water tank 403 is sprayed to the coarse filter 502 through the nozzle 405 by the water pump 404. The coarse filter 502 is a stainless steel filter. Clean water can be added to the water tank 403 in advance to ensure that there is sufficient water in the water tank 403. The coarse filter 502 is rinsed and cleaned by the water in the water tank 403 to achieve self-cleaning of the coarse filter 502 in the tank body 201. The impurities and waste water that are brushed off fall onto the surface of the guide filter 6 and enter the storage box 603 through the guide port 602 along the curved surface of the guide filter 6 for collection. The storage box 603 is detachably mounted on the tank body 201. The storage box 603 is made of a transparent material and is provided with a drain pipe connected to the outside of the shell 1.

[0061] Furthermore, in order to further improve the cleaning efficiency of the coarse filter 502, the filter hole diameter of the guide filter 6 is set to be smaller than the filter hole diameter of the coarse filter 502. The small filter hole diameter of the guide filter 6 cooperates with its curved surface structure to ensure that impurities and wastewater are accelerated to move to the edge for collection. When the gas passes through the rotating impeller 8021, the rotating groove 806 in the rotating groove 806 keeps the limit ring 807 locked, and the electromagnetic latch in the slot 8022 keeps the bottom end of the lower rotating rod 5012 locked. Under the cooperation of the lower tooth ring 803 and the upper tooth ring 805, the lower tooth ring 803 continuously slides in and out between the two adjacent upper tooth rings 805 When the lower tooth ring 803 and the upper tooth ring 805 are in contact with each other, the upper surface of the guide filter 6 is away from the supporting seat 503, and the spring 50131 is expanded and stretched. When the lower tooth ring 803 slides between the two adjacent upper tooth rings 805, the upper surface of the guide filter 6 contacts the supporting seat 503, and the spring 50131 contracts and resets. As the rotating ring 802 repeatedly approaches and moves away from the fixed ring 804, the guide filter 6 repeatedly contacts and collides with the supporting seat 503, so that the supporting seat 503 transmits force to multiple coarse-effect filter screens 502, causing the coarse-effect filter screens 502 to vibrate, thereby accelerating the separation speed of impurities and wastewater from the coarse-effect filter screens 502.

[0062] Moreover, the vibration generated when the guide filter 6 contacts the supporting seat 503 also acts on the guide filter 6. Through the high-frequency vibration of the guide filter 6, the speed of the wastewater and impurities on the guide filter 6 moving to the outside is accelerated, thereby greatly shortening the cleaning time of the coarse filter 502 and the guide filter 6, and at the same time reducing the humidity of the coarse filter 502 and the guide filter 6, preventing impurities and water from gathering in the guide filter 6 and hindering the circulation of gas. In addition, a dehumidification component for use in the filter tank 2 is also provided in the filter tank 2. As an implementation method of the dehumidification component, the dehumidification component can collect the hot air generated by the heating end of the semiconductor refrigeration plate, and cooperate with the circulating fan to circulate and dry the filter tank 2 when it is necessary to dry the filter tank 2.
