Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Depend on Figure 1-9 The present invention relates to a medium filtration system with advanced oxidation function, comprising a cylinder 1, an outer wall of the cylinder 1 is fixedly provided with an air inlet pipe 3 along its circumference, a plurality of air inlet pipes 3 are provided, and the plurality of air inlet pipes 3 are evenly distributed along the circumference of the cylinder 1, and an air inlet fan 4 is fixedly provided inside the air inlet pipe 3; an air outlet pipe 49 is fixedly provided at the top center of the cylinder 1, an air outlet fan 5 is fixedly provided inside the air outlet pipe 49, filter plates 45 are fixedly provided at the pipe openings of the air inlet pipe 3 and the pipe openings of the air outlet pipe 49, and a handle 46 is hingedly provided at the top of the cylinder 1; a filter screen 6 and a medium filtration unit are fixedly provided inside the cylinder 1; the filter screen 6 is located between the cylinder 1 and the medium filtration unit; a dust outlet 47 is opened in the space formed between the cylinder 1 and the filter screen 6, the dust outlet 47 is connected to the bottom box 2, and an end cover 48 is sealed inside the dust outlet 47.

[0035] When in use, both the air inlet fan 4 and the air outlet fan 5 are working, and the indoor air is sucked in through the air inlet fan 4 in the air inlet pipe 3, and then the dust in the air is filtered through the filter net 6, and then the harmful gas in the air is purified through the medium filter unit, and then under the action of the air outlet fan 5 in the air outlet pipe 49, the purified air is discharged into the room, realizing the circulation purification process of the indoor air to improve the quality of the indoor air.

[0036] It should be noted that when a lot of dust accumulates between the cylinder 1 and the filter 6, the bottom box 2 can be disassembled and the end cover 48 can be removed, so that the dust can be discharged from the dust outlet 47, and the dust can be cleaned regularly.

[0037] In order to solve the problem that during the use of the cylindrical medium filter unit, since the ultraviolet lamp is located at the center, the ultraviolet rays can only irradiate the inner wall of the cylindrical medium filter unit with high intensity, while the outer wall of the cylindrical medium filter unit cannot receive the irradiation of ultraviolet light, so the adsorbent on the outer wall of the cylindrical medium filter unit cannot be fully utilized; In order to solve the above technical problems, the medium filter unit in the present invention includes an upper ring frame 7, a lower ring frame 8, a partition 9, a purification cylinder 10, a middle ultraviolet filter 11, and a middle ultraviolet filter 12. The outer lamp tube 11 and the driving mechanism; wherein the upper ring frame 7 is fixedly arranged at the bottom end of the air inlet pipe 3; the lower ring frame 8 is fixedly arranged on the inner bottom wall of the cylinder body 1; a plurality of partitions 9 are provided and fixedly arranged between the upper ring frame 7 and the lower ring frame 8 along the circumferential direction; a plurality of purification cylinders 10 are provided and arranged between the upper ring frame 7 and the lower ring frame 8 along the circumferential direction, and the purification cylinders 10 and the partitions 9 are arranged alternately; the medium ultraviolet lamp tube 11 is fixedly arranged on the inner bottom wall of the cylinder body 1 and is located at the center of the plurality of purification cylinders 10; the driving mechanism is fixedly arranged on the upper ring frame 7;

[0038] Specifically, the purification cartridge 10 includes an upper cover plate 12, a lower cover plate 13, a middle filter cartridge 14 and an inner ultraviolet lamp 15; wherein the upper cover plate 12 is fixedly arranged at the bottom end of the upper ring frame 7; the lower cover plate 13 is fixedly arranged at the top end of the lower ring frame 8; the middle filter cartridge 14 is rotatably arranged between the upper cover plate 12 and the lower cover plate 13, and the middle filter cartridge 14 is loaded with an adsorbent, such as manganese dioxide, nano zinc and other adsorbents, which can effectively adsorb harmful gases such as formaldehyde in the room under ultraviolet light catalysis, and the inner ultraviolet lamp 15 is fixedly arranged between the upper cover plate 12 and the lower cover plate 13, and is located on the inner side of the middle filter cartridge 14;

[0039] With such a design, when in use, the air needs to first pass through the wall of the middle filter cartridge 14 to enter the interior of the middle filter cartridge 14, and then pass through the wall of the middle filter cartridge 14 again to enter the center of the cylinder body 1; during this period, the inner wall of the middle filter cartridge 14 can be irradiated with high-intensity ultraviolet light through the internal ultraviolet lamp 15 to ensure the adsorption effect of the adsorbent located on the inner side of the middle filter cartridge 14; at the same time, the middle filter cartridge 14 is driven to rotate by the driving mechanism, and the outer wall of the rotated middle filter cartridge 14 can be continuously irradiated by the middle ultraviolet lamp 11, which can also ensure the adsorption effect of the adsorbent on the outer side of each middle filter cartridge 14.

[0040] It should be noted that after the adsorbent is catalyzed by ultraviolet light, for example, the adsorbent is manganese dioxide, it can enhance the oxidation effect on harmful formaldehyde gas after ultraviolet light irradiation, so that formaldehyde is decomposed to form carbon dioxide and water, and thus has advanced oxidation function.

[0041] Specifically, the driving mechanism includes a driving motor 16, a driving gear 17, a driven gear ring 18 and a mounting ring 19; wherein a horizontal frame 20 is fixedly arranged on the upper ring frame 7, and the driving motor 16 is fixedly arranged on the horizontal frame 20; the driving gear 17 is fixedly arranged on the output shaft of the driving motor 16 and meshes with the driven gear ring 18; the driven gear ring 18 is fixedly arranged at the bottom end of the mounting ring 19, and the teeth on the outer side of the driven gear ring 18 mesh with the teeth on the outer side of the middle filter cartridge 14; the outer wall of each upper cover plate 12 is provided with an outer arc groove 21, and a plurality of outer arc grooves 21 are located on the same circumference, and the mounting ring 19 is rotatably arranged in the plurality of outer arc grooves 21;

[0042] In this design, the driving motor 16 drives the driving gear 17 to rotate, the driving gear 17 drives the driven ring gear 18 to rotate by meshing, and the teeth on the outside of the driven ring gear 18 drive the tooth grooves on the outside of the middle filter cartridge 14 to rotate by meshing, thereby realizing the driving process of the middle filter cartridge 14.

[0043] Considering that after a long period of use, the outer wall and the inner wall of the middle filter cartridge 14 will be attached with a lot of dust, thereby reducing the contact area between the adsorbent and the harmful gas and reducing the adsorption efficiency of the adsorbent, in order to solve this problem, the medium filter unit of the present invention also includes a self-cleaning mechanism, which includes a suction filtration device; wherein the lower ring frame 8 is provided with an air inlet channel 22 and an air outlet channel 23, the partition plate 9 is symmetrically provided with an outer cleaning channel 24, the upper ring frame 7 is provided with a connecting channel 25, and the upper cover plate 12 is provided with an upper connecting channel 26. The connecting hole 26, an inner cleaning pipe 27 with a lateral opening is fixedly arranged between the upper cover plate 12 and the lower cover plate 13, the inner cleaning pipe 27 is fitted on the middle filter cartridge 14, and a lower connecting hole 28 is opened in the lower cover plate 13; wherein one end of the suction filter device is connected with the air inlet channel 22, the air inlet channel 22 is connected with the outer cleaning channel 24 through a conduit, the outer cleaning channel 24 is connected with the air outlet channel 23 through the connecting channel 25, the upper connecting hole 26, the inner cleaning pipe 27, and the lower connecting hole 28 in sequence, and the air outlet channel 23 is connected with the other end of the suction filter device;

[0044] With such a design, when in use, a wind flow is generated by the suction filtering device, and the wind flow enters into the interior of the external cleaning channel 24 through the air inlet channel 22 and the duct, and the dust on the outer wall of the middle filter cartridge 14 is blown away by the wind flow. A part of it enters into the internal cleaning pipe 27 through the connecting channel 25 and the upper connecting hole 26, and the other part passes through the cylinder wall of the middle filter cartridge 14 and enters into the interior of the internal cleaning pipe 27, during which the wind flow blows away the dust inside the middle filter cartridge 14; then the wind flow in the internal cleaning pipe 27 returns to the interior of the suction filtering device through the lower connecting hole 28 and the air outlet channel 23, and the dust in the circulating wind flow is filtered by the suction filtering device.

[0045] Specifically, a bottom box 2 is also detachably provided below the cylinder 1, and a suction and filtering device is located inside the bottom box 2. The suction and filtering device includes an exhaust fan 29 and a filter box 30. The exhaust fan 29 and the filter box 30 are both fixedly provided inside the bottom box 2. A filter screen, a filter element and other structures are provided inside the filter box 30 to filter dust, which belongs to conventional technology and will not be described in detail. One end of the exhaust fan 29 is connected to the air inlet channel 22, and the other end of the exhaust fan 29 is connected to the filter box 30, and the filter box 30 is connected to the air outlet channel 23.

[0046] With this design, the exhaust fan 29 can generate a wind flow, and the dust in the recovered wind flow can be removed through the filter box 30 to ensure the cleanliness of the circulating wind flow.

[0047] Due to the long-term accumulation of dust, some filaments will be attached to the outer wall of the cylinder 1, which is difficult to remove only by the blowing of wind and airflow. Therefore, in order to solve this problem, the external cleaning channel 24 of the present invention includes a front tank body 31 and a rear tank body 32, the front tank body 31 is connected to the rear tank body 32, and the top and bottom of the connection between the front tank body 31 and the rear tank body 32 are both provided with a strip groove 33; wherein an active cleaning member is arranged in the front tank body 31, and the active cleaning member includes an outer cleaning block 34 and an inner sliding block 35; wherein the outer cleaning block 34 is slidably arranged in the front tank body 3 1, the outer cleaning block 34 is provided with an air vent 36 and an inner slide groove 37, the air vent 36 and the inner slide groove 37 are relatively perpendicular and connected; the inner sliding block 35 is slidably arranged in the inner slide groove 37, a movable magnetic block 38 is fixedly arranged on a side of the inner sliding block 35 close to the rear tank body 32, and an upper magnetic block 39 and a lower magnetic block 40 are fixedly arranged at positions opposite to the two strip grooves 33 on the rear tank body 32, the upper magnetic block 39 is located above the lower magnetic block 40, wherein the movable magnetic block 38 and the upper magnetic block 39 are magnetically attracted to each other, and the movable magnetic block 38 and the lower magnetic block 40 are magnetically repelled;

[0048] With this design, when in use, when the outer cleaning block 34 is located at the bottom of the front slot body 31, under the magnetic repulsion of the lower magnetic block 40 and the movable magnetic block 38, the inner sliding block 35 slides in the inner slide groove 37 to block the air vent 36, thereby increasing the contact area between the outer cleaning block 34 and the wind flow. At this time, under the action of the wind flow, the outer cleaning block 34 is displaced upward and the outer wall of the filter cartridge 14 is cleaned by the cleaning brush provided on the outer cleaning block 34. When the outer cleaning block 34 moves to the top of the front slot body 31, under the magnetic attraction of the upper magnetic block 39 and the movable magnetic block 38, the inner sliding block 35 is moved in the inner slide groove. After sliding inwardly, the air hole 36 is unblocked, and the tail end of the inner sliding block 35 passes through the strip groove 33 located above and is placed in the rear tank body 32. At this time, due to the reduction in the contact area between the wind force and the outer cleaning block 34, the outer cleaning block 34 slides down along the front tank body 31 under the action of the deadweight of the outer cleaning block 34 and the inner sliding block 35, and at the same time, the tail end of the inner sliding block 35 slides down along the rear tank body 32 until it falls to the bottom of the rear tank body 32, and then under the action of magnetic repulsion, the inner sliding block 35 blocks the air hole 36 again, and the cyclic action causes the outer cleaning block 34 to continuously move up and down to clean the outer wall of the filter cartridge 14;

[0049] During this period, when the outer cleaning block 34 moves to the top of the front slot 31 and the inner sliding block 35 releases the blockage of the air vent 36, the wind flow can enter the inner cleaning pipe 27 through the air vent 36, the connecting channel 25, and the upper connecting hole 26, and then enter the air outlet channel 23 through the lower connecting hole 28, and finally be transported to the filter box 30 for filtration to complete the cleaning of the dust.

[0050] Further, a driven cleaning member is arranged inside the inner cleaning tube 27, and the driven cleaning member includes a driven cleaning block 41, which is slidably arranged inside the inner cleaning tube 27, and a driven magnetic block 42 is fixedly arranged on the driven cleaning block 41, and an active magnetic block 43 is fixedly arranged on the outer cleaning block 34, and the active magnetic block 43 and the driven magnetic block 42 are magnetically attracted to each other, and a through hole 44 is opened in the middle of the driven cleaning block 41;

[0051] With this design, the driven cleaning block 41 can be driven to move by the magnetic attraction of the active magnetic block 43 and the driven magnetic block 42, and the inner wall of the center filter cartridge 14 can be cleaned by the cleaning brush provided on the driven cleaning block 41. At the same time, under the magnetic force of the active magnetic block 43 and the driven magnetic block 42, the cleaning force of the cleaning brushes on both sides on the inner wall or outer wall of the center filter cartridge 14 can be ensured, thereby further improving the cleaning effect.

[0052] It should be noted that during use, the middle filter cartridge 14 can be rotated at a certain angle at regular intervals. In this way, when the middle filter cartridge 14 stops rotating, a relatively closed space can be maintained between the inner cleaning tube 27 and the middle filter cartridge 14, as well as between the outer cleaning channel 24 and the middle filter cartridge 14. In this way, only the dust cleaning area on the middle filter cartridge 14 is cleaned, and the rest of the working area on the middle filter cartridge 14 is not affected, so that the middle filter cartridge 14 can adsorb harmful gases.

[0053] A method for operating a media filtration system with an advanced oxidation function comprises the following steps:

[0054] First, air is taken in through the air intake fan 4 to draw in the outside air, then the dust in the air is filtered through the filter 6, and then the harmful gas in the air is purified through the medium filter unit, and finally the purified air is discharged through the air outlet fan 5.

[0055] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
