[0019] Compared with the prior art, the beneficial effects of this utility model are: this fresh air filter device with pollen-blocking function allows for simultaneous cleaning of both the coarse and fine filters, preventing clogging. Furthermore, it collects the dust removed during cleaning, preventing dust dispersion from affecting the cleaning effect and improving practicality. The specific details are as follows:

[0020] 1. The wall-mounted frame is fixed to the wall. Through coarse and fine filters, air is filtered during ventilation, preventing pollen from entering the room. When cleaning the coarse and fine filters, a multi-stage electric push rod and fan are activated, causing the movable plate to move upwards. This upward movement allows the brushes on the brush plate to clean the coarse and fine filters. The coarse filter has larger holes, allowing the brush bristles to pass through and clean the filter side. If dust is generated during cleaning, the fan activates, creating a negative pressure inside the housing. Air is then drawn in through two sets of braided hoses, allowing the cleaned dust to enter the housing and then through a telescopic tube into the exhaust pipe. A breathable dust collection bag collects the dust; this bag is removable for easy cleaning. This allows for simultaneous cleaning of both coarse and fine filters, preventing clogging and ensuring effective dust collection during cleaning, thus improving practicality.

[0021] 2. During the cleaning process, the movable plate continuously moves upward. The movement of the movable plate allows the roller to abut against the protrusion. The movement of the movable plate causes the protrusion to push the roller to move, which in turn causes the moving rod to move. This causes the mounting rod to slide on the fixed block and stretch the telescopic spring. After the moving rod moves, it can drive the rotating rod to rotate through the connection between the rack and the rotating gear. This causes the suction end of the braided hose to rotate. After the roller leaves the protrusion, the moving rod returns to its original position under the action of the telescopic spring. This allows the suction end of the braided hose to swing back and forth during the cleaning process, thereby expanding the suction cleaning range and improving the dust collection effect.

L-shaped frames 205 are symmetrically installed on both sides of the top of the movable plate 202, and brush plates 206 are fixedly installed on one end of each of the two L-shaped frames 205. A housing 207 is fixedly installed at the bottom of the movable plate 202, and a fan 208 is fixedly installed inside the housing 207. This allows for simultaneous cleaning of the coarse filter 101 and the fine filter 102, preventing clogging. During the cleaning process, the dust can be collected to prevent dust from spreading and affecting the cleaning effect, thus improving practicality.

[0031] A telescopic tube 209 is connected through the bottom of the housing 207, and an installation hopper 204 is connected through the bottom of the wall connection frame 1 below the movable plate 202. A discharge pipe 210 is connected through the bottom of the installation hopper 204, and the bottom end of the telescopic tube 209 is connected through the discharge pipe 210 to discharge collected dust. A breathable dust collection bag 211 is installed at the bottom of the discharge pipe 210, and an installation ring 212 is fixedly installed at the top of the breathable dust collection bag 211. An external thread is provided on the lower outer side of the discharge pipe 210, and the installation ring 212 is threadedly connected to the discharge pipe 210. For dust collection, two sets of braided hoses 213 are symmetrically connected to both sides of the housing 207. Each set of three braided hoses 213 has a dust collection hood connected to the end furthest from the housing 207. A fixing ring 214 is fixedly installed on the outer side of each braided hose 213, and a rotating rod 215 is fixedly installed on the top of the fixing ring 214. A mounting block 216 is rotatably connected to the outside of the rotating rod 215, and the mounting block 216 is fixedly connected to the movable plate 202 for easy dust collection. Moving rods 218 are symmetrically arranged on both sides of the movable plate 202, and the outer sides of the two moving rods 218... Two sets of positioning blocks 220 are symmetrically slidably connected, and the positioning blocks 220 are fixedly connected to the movable plate 202. Rotating gears 217 are fixedly installed at the top of each of the two sets of rotating rods 215. Two moving rods 218 are located on one side of each of the two sets of rotating gears 217 and are fixedly installed with racks 219, which mesh with the rotating gears 217. This allows the moving rods 218 to rotate the rotating rods 215. Mounting brackets 221 are symmetrically installed at one end of each of the two moving rods 218, and rollers 222 are rotatably connected between the two mounting brackets 221.

The other end of the two moving rods 218 is fixedly installed with a mounting rod 224, and a fixing block 225 is slidably connected to the outer side of the mounting rod 224. A telescopic spring 226 is sleeved on the outer side of the mounting rod 224 on the side of the fixing block 225. The two ends of the telescopic spring 226 are fixedly connected to the fixing block 225 and the mounting rod 224 respectively. The fixing block 225 is fixedly connected to the movable plate 202, which facilitates the reset of the moving rods 218 after they move.

[0032] Working principle: Before using this fresh air filter device with pollen-blocking function, it is necessary to check the overall condition of the device to ensure it can function properly. Figure 1 - Figure 6As shown, the wall connection frame 1 is fixed to the wall. The coarse filter 101 and fine filter 102 filter the air during ventilation, preventing pollen from entering the room. When cleaning the coarse filter 101 and fine filter 102, the multi-stage electric push rod 201 and fan 208 are activated, causing the movable plate 202 to move upwards. The upward movement of the movable plate 202 allows the brush bristles on the brush plate 206 to clean the coarse filter 101 and fine filter 102. The coarse filter 101 has relatively large holes, allowing the brush bristles to pass through and clean the filter side. If dust is generated during the cleaning process... When the fan 208 is started, the inside of the housing 207 is under negative pressure. Air can be drawn in through two sets of braided hoses 213, allowing the cleaned dust to enter the housing 207 through the braided hoses 213. Then, it can enter the discharge pipe 210 through the telescopic pipe 209. The dust can be collected through the breathable dust collection bag 211, which can be disassembled for easy cleaning. This allows for simultaneous cleaning of the coarse filter 101 and the fine filter 102, preventing clogging. The dust collected during the cleaning process prevents dust from spreading and affecting the cleaning effect, thus improving practicality.

[0033] During the cleaning process, the movable plate 202 moves upward continuously. The movement of the movable plate 202 allows the roller 222 to abut against the protrusion 223. The moving protrusion 223 of the movable plate 202 can push the roller 222 to move, causing the moving rod 218 to move. This causes the mounting rod 224 to slide on the fixed block 225 and stretch the telescopic spring 226. After the moving rod 218 moves, it can drive the rotating rod 215 to rotate through the connection between the rack 219 and the rotating gear 217. This causes the suction end of the braided hose 213 to rotate. After the roller 222 leaves the protrusion 223, the moving rod 218 returns to its original position under the action of the telescopic spring 226. This allows the suction end of the braided hose 213 to swing back and forth during the cleaning process, thereby expanding the suction cleaning range and improving the dust collection effect.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
