DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] The terms such as "upper", "lower", "left", "right", "middle" and "one" cited in the present utility model are only for the convenience of description and are not used to limit the scope of application of the present utility model. Changes or adjustments in their relative relationships shall be regarded as the scope of application of the present utility model without substantially changing the technical content.

[0023] Reference Figure 1-Figure 5 , a disinfection and purification device installed in a central air conditioning fresh air system, comprising a purification box 1, a light hydrogen ion sterilization module body, a blue antibacterial layer, a centrifugal fan body 8, a plurality of air ducts and a box cover 2. When the box cover 2 and the purification box 1 are snapped together, the sealing performance of the connection between the purification box 1 and the box cover 2 is good, and the connection is very firm. The upper and lower inner walls of the purification box 1 are fixedly connected to two limit blocks 12, and three filter screens 9 are arranged between the plurality of limit blocks 12. Each limit block 12 is rotatably connected to a rotating rod 5 with an L-shaped cross section, and one end of each rotating rod 5 is fixedly connected to a limit plate 10, and each rotating rod 5 is fixedly connected to a plurality of extrusion cams 11. Two ear plates 3 are fixedly connected to the back of the purification box 1, and a bidirectional screw rod 4 is rotatably arranged between the two ear plates 3. Two sliders 6 are threadedly connected to the bidirectional screw rod 4, and two extrusion rods 7 are fixedly connected to each slider 6. A rotating wheel 15 is fixedly connected to the bidirectional screw rod 4, and a sliding component is arranged on the purification box 1.

[0024] The three filters 9 include a primary fiber washable filter, a silver ion photocatalyst filter and a HEPA12 high-efficiency filter. The primary fiber washable filter is suitable for primary filtration of the air conditioning system and can be washed. The air is initially filtered and the filtered air passes through the silver ion photocatalyst filter. The silver ion photocatalyst filter is mainly made of titanium dioxide photocatalyst as a raw material. Under photocatalytic conditions, active oxygen is generated, which has a strong bactericidal effect. The light hydrogen ion sterilization module body is composed of a base plate, a ballast, a lamp holder, and an ultraviolet lamp tube. The light hydrogen ion Sub-technology can effectively purify the air and remove harmful substances such as bacteria, viruses, formaldehyde, benzene, ammonia, sulfide, etc. in the room, so that the silver ion photocatalyst filter cooperates with the ultraviolet lamp to sterilize the passing air, so that the sterilized air passes through the HEPA12 high-efficiency filter. The HEPA12 high-efficiency filter can effectively filter out more than 95% of air pollutants in the air, including bacteria, viruses and antibiotics, thereby filtering pollutants from the passing air, etc., so that the light hydrogen ion sterilization module body can disinfect and purify the air after three filtrations.

[0025] Each rotating rod 5 is sleeved with a torsion spring 13, one end of the torsion spring 13 is fixedly connected to the rotating rod 5, and the other end of the torsion spring 13 is fixedly connected to the back of the purification box 1. When the rotating rod 5 loses the squeezing effect of the squeezing rod 7, under the elastic force of the torsion spring 13, the rotating rod 5 will rotate relative to the corresponding limit block 12. The cross-section of each slider 6 is T-shaped. Two slide grooves 14 for connecting the slider 6 are provided on the back of the purification box 1. The slide groove 14 can limit the moving trajectory of the slider 6, and can prevent the slider 6 from swinging during the rotation of the bidirectional screw rod 4.

[0026] A groove is provided on the back of the purification box 1, and the sliding assembly includes a sliding rod 16 slidably installed in the groove, an arc block 18 is fixedly connected to the sliding rod 16, the surface of the arc block 18 is in contact with the surface of the rotating wheel 15, and a first spring 17 is sleeved on the sliding rod 16, one end of the first spring 17 is fixedly connected to the sliding rod 16, and the other end of the first spring 17 is fixedly connected to the inner wall of the groove. In the initial state, under the elastic force of the first spring 17, the rubber surface of the arc block 18 is in close contact with the surface of the rotating wheel 15, and the friction between the arc block 18 and the rotating wheel 15 is relatively large, which can effectively prevent the rotating wheel 15 from rotating at will.

[0027] Two limit rings are fixedly connected to the bidirectional screw rod 4, and the two limit rings are respectively fitted with the surfaces of the two ear plates 3. The two limit rings have a certain limiting effect on the bidirectional screw rod 4 to prevent the bidirectional screw rod 4 and the ear plates 3 from detaching.

[0028] In the present invention, when the filter screen 9 needs to be removed for cleaning, the box cover 2 and the card slot on the purification box 1 are first disengaged, and then the slide bar 16 is pushed to extend it toward the inside of the groove, and the first spring 17 is deformed. Under the transmission action of the slide bar 16, the rubber surface of the arc block 18 is disengaged from the rotating wheel 15, and then the rotating wheel 15 is rotated, thereby causing the bidirectional screw rod 4 and the ear plate 3 to rotate relative to each other, and the two sliders 6 move along the bidirectional screw rod 4, and the distance between the two sliders 6 is reduced. After each extrusion rod 7 moves with the corresponding slider 6, one end of the extrusion rod 7 is gradually disengaged from the surface of the L-shaped rotating rod 5, and the extrusion rod 5 is lost. Due to the squeezing effect of the rod 7, under the elastic force of the torsion spring 13, the rotating rod 5 will rotate relative to the corresponding limit block 12. In the initial state, each squeezing cam 11 is respectively in close contact with the surface of the filter screen 9 on both sides, and each limit plate 10 is respectively in close contact with the front side surfaces of the two corresponding filter screens 9. After the rotating rod 5 is rotated, each squeezing cam 11 will be separated from the surface of the filter screen 9, and each limit plate 10 is located on the left and right sides of each filter screen 9 at the same time. At this time, each filter screen 9 can be pulled outward and taken out of the purification box 1 for cleaning. The operation is relatively convenient and quick, and the filter screen 9 can be quickly disassembled, which is beneficial to the disinfection and purification of the fresh air system.

[0029] In the present invention, unless otherwise clearly specified or limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
