DETAILED DESCRIPTION

[0025] 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 the embodiments.

[0026] Embodiment: This embodiment discloses an intelligent fresh air purification device, such as Figure 1-Figure 7 The invention comprises: a box body 1, a pair of shutter doors 101 are provided at one air inlet end of the box body 1, the shutter doors 101 can be opened, and a fan 3 is installed at the other end of the box body 1; air enters from the shutter doors 101 of the box body 1 and is discharged through the fan 3; an interception mechanism 2, a primary filter 4, a secondary filter 5 and a cooling wet curtain 6 are sequentially provided in the box body 1 along the air flow direction, wherein the primary filter 4, the secondary filter 5 and the cooling wet curtain 6 are assembled together in blocks, and the heights of the primary filter 4, the secondary filter 5 and the cooling wet curtain 6 are the same as the height of the box body 1; wherein the interception mechanism 2 is used to The microbial carriers include small insects of the order Diptera, and the microorganisms include viruses and bacteria. The interception mechanism 2 intercepts the pathogens and virus carriers, effectively reducing the probability of virus and pathogen transmission in the breeding circle. The first-level filter 4 adopts a G4-level primary filter with non-woven fabrics, glass fibers, etc. as filter materials, and mainly intercepts large particles of dust. The second-level filter 5 adopts an F9 sub-high efficiency filter as the final filtering protection layer, which mainly intercepts small particles of dust, aerosols, pollen, fibers, etc. The cooling wet curtain 6 plays a role in regulating air humidity and temperature.

[0027] Preferably, a treatment chamber 102 is provided in the box body 1 below the interception mechanism 2. The bottom of the treatment chamber 102 can be filled with a sterilizing liquid of a certain depth. The liquid height can be about 10 cm, and the liquid can be discharged and replaced regularly. The liquid is used to sterilize and inactivate the cleaned microbial carriers, and an ultraviolet lamp 7 is provided on the inner wall of the treatment chamber 102 for sterilization and disinfection.

[0028] like Figure 2-Figure 4 As shown, the interception mechanism 2 includes a rotating roller 22 and a driving motor 21, the driving motor 21 is used to drive the rotating roller 22 to rotate, a pair of connecting seats 26 are symmetrically fixedly connected to the surface of the rotating roller 22, and the connecting seats 26 are connected to a first interception net 24 and a second interception net 25 parallel to each other, and the first interception net 24 and the second interception net 25 are made of stainless steel net and high-density nylon net; wherein, the filter hole size of the first interception net 24 is larger than the filter hole size of the second interception net 25, the microbial carrier can pass through the first interception net 24 but cannot pass through the second interception net 25, and a gap of adjustable size is provided between the second interception net 25 and the first interception net 24; when the microbial carrier passes through the shutter door After 101 enters the box body 1, the microbial carrier passes through the first interception net 24. Due to the special body structure of the microbial carrier, it is clamped in the gap between the first interception net 24 and the second interception net 25, and then the microbial carrier near the farm is captured; wherein, the second interception net 25 is fixedly connected to the connecting seat 26, and one side of the first interception net 24 is rotatably connected to multiple connecting rods 222, and one end of the connecting rod 222 is rotatably connected to one side of the second interception net 25; when the first interception net 24 moves upward, the connecting rod 222 rotates, and the gap between the first interception net 24 and the second interception net 25 increases, which facilitates the microbial carrier to fall from the gap into the treatment chamber 102.

[0029] like Figure 4 and Figure 6As shown, a cleaning brush 27 is connected to the connecting seat 26 for cleaning the microorganism carrier between the first interception net 24 and the second interception net 25; a slide rail 29 is vertically fixedly connected to the connecting seat 26, and a slide seat 28 is slidably connected to the slide rail 29. The cleaning brush 27 is rotatably connected to the slide seat 28. When the slide seat 28 slides along the slide rail 29, it can drive the cleaning brush 27 to move between the first interception net 24 and the second interception net 25; and a first gear 215 is coaxially fixedly connected to the cleaning brush 27, and a rack 210 meshing with the first gear 215 is fixedly connected to the slide rail 29; a transmission belt 214 is connected to the slide rail 29 for driving the slide seat 28 to move, and the transmission belt 214 is fixedly connected to the slide seat 28, and two ends of the slide rail 29 are connected with a The transmission wheel 213 cooperates with the transmission belt 214, and one of the transmission wheels 213 is coaxially fixedly connected with the second gear 216; when the transmission belt 214 moves, it drives the slide 28 to move along the slide rail 29, and then drives the cleaning brush 27 to move in the gap between the first interception net 24 and the second interception net 25. During the movement, the first gear 215 rolls along the surface of the rack 210, driving the cleaning brush 27 to rotate itself, and then cleaning the surface of the first interception net 24 and the second interception net 25, cleaning the microbial carriers on the surface and dropping them into the processing chamber 102. After cleaning, the transmission belt 214 moves in the opposite direction, driving the cleaning brush 27 to move out of the gap between the first interception net 24 and the second interception net 25 and return to its original position.

[0030] like Figure 5-Figure 6 As shown, the interception mechanism 2 also includes a transmission mechanism 23 that cooperates with the second gear 216. The transmission mechanism 23 can be installed on the inner wall of the box body 1 to drive the second gear 216 to rotate back and forth; the transmission mechanism 23 includes an incomplete outer gear ring 232 and an incomplete inner gear ring 231. The incomplete inner gear ring 231 is arranged on the periphery of the incomplete outer gear ring 232, and the incomplete outer gear ring 232 and the incomplete inner gear ring 231 are both fixed and remain motionless. When the rotating roller 22 rotates 0-360°, the second gear 216 is meshed with the incomplete inner gear ring 231 and the incomplete outer gear ring 232 respectively, so that the second gear 216 rotates in opposite directions twice, thereby driving the transmission belt 214 to different directions. The first interception net 24 is fixedly connected to a bracket 211, and the bracket 211 is connected to a roller 212. The outer periphery of the incomplete inner gear ring 231 is fixedly connected to a track ring 233 that cooperates with the roller 212. The track ring 233 is provided with a groove 234. When the roller 212 rolls and the groove 234 is located, the gap between the first interception net 24 and the second interception net 25 is the smallest, and the microorganism carrier is intercepted at this time; when the roller 212 moves out of the groove 234, it will drive the first interception net 24 to move, and the gap between the first interception net 24 and the second interception net 25 will increase, and the microorganism carrier is in a cleaning state at this time.

[0031] like Figure 7 As shown, a plurality of limit frames 221 are fixedly connected to the second interception net 25, and a strip hole 217 is provided on the limit frame 221. A limit rod 218 cooperating with the strip hole 217 is fixedly connected to the first interception net 24, and a cylindrical spring 219 is connected to the surface of the limit rod 218, and a retaining ring 220 is fixedly connected to the upper end of the limit rod 218. The cylindrical spring 219 applies downward pressure to the first interception net 24, so that the roller 212 is pressed tightly against the surface of the track ring 233.

[0032] Working principle: the shutter door is opened, and air enters the box body 1 through the air inlet. The air is purified by the interception mechanism 2, the primary filter 4, the secondary filter 5 and the cooling wet curtain 6 in sequence, wherein the microbial carriers in the air are intercepted between the first interception net 24 and the second interception net 25. When the interception mechanism 2 needs to be cleaned, the driving motor 21 drives the rotating roller 22 to rotate from 0° to 180°. During the rotation, the roller 212 rolls out of the groove 234, so that the gap between the first interception net 24 and the second interception net 25 increases, and then the second gear 216 rolls on the surface of the incomplete inner gear ring 231, driving the transmission belt 214 to move, and the transmission belt 214 drives the cleaning brush 27 to move away from the connecting seat 26 to the first interception net At the other end of the first interception net 24, during the movement, the first gear 215 rolls along the surface of the rack 210, driving the cleaning brush 27 to rotate, and then the microbial carriers between the first interception net 24 and the second interception net 25 are cleaned, and the microbial carriers fall into the processing chamber 102, completing the cleaning of the interception mechanism 2; when the rotating roller rotates from 180° to 360°, the second gear 216 rolls along the surface of the incomplete outer gear ring 232, driving the transmission belt 214 to move in the opposite direction, and then driving the cleaning brush 27 to move toward the connecting seat 26 until it moves out of the gap between the first interception net 24 and the second interception net 25. During the movement, the cleaning brush 27 cleans the surface of the first interception net 24 and the second interception net 25 again.

[0033] This embodiment discloses a control system for an intelligent fresh air purification device. Figure 8 As shown, it includes a control terminal 8, a cleanliness detection module 9 and a power module 10. The power module 10 provides electrical energy. The cleanliness detection module 9 is used to detect the cleanliness of the surface of the first interception net 24 and the second interception net 25 and send a signal to the control terminal. The cleanliness detection module 9 can use a cleanliness sensor to monitor the surface of the first interception net 24 and the second interception net 25. When there are too many microbial carriers intercepted on the surface of the first interception net 24 and the second interception net 25, the cleanliness detection module 9 sends a signal to the control terminal 8, and the control terminal 8 controls the drive motor 21 to start, drive the rotating roller 22 to rotate, and clean the surface of the first interception net 24 and the second interception net 25.
