DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be apparently and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the utility model.

[0025] As Figures 1-6 shown, the utility model provides a kind of fresh air dehumidification heat recovery system embodiment.

[0026] A kind of fresh air dehumidification heat recovery system, including fresh air dehumidification device body, the side fixed mounting of fresh air dehumidification device body has air inlet and exhaust port, air inlet and exhaust port are all fixedly installed with filter box, and fixed mechanism is set on the surface of filter box, and fixed mechanism includes multiple support rods fixedly installed on the surface of fresh air dehumidification device body, and the surface of filter box is fixedly installed with the support frame for cooperation with support rod, and support frame is provided with clamping rod installed and connected by two first springs, and clamping groove is opened on support rod and matched with clamping rod, and multiple tooth blocks are uniformly fixedly installed on the side of clamping rod, and the side of support frame is provided with toothed plate installed and connected by multiple second springs, and toothed plate and tooth block are mutually engaged. By the setting of fixed mechanism, replace the mode of traditional bolt fixation to install filter box on air inlet and exhaust port, and filter box is fixed by the clamping of clamping rod and clamping groove in fixed mechanism, when disassembling, pull up clamping rod to make it separate from clamping groove, then toothed plate and tooth block on clamping rod are engaged to fix clamping rod and prevent falling, then filter box can be removed from air inlet and exhaust port, convenient to disassemble filter box, can maintain filter box in time.

[0027] In the embodiment, as shown in Figures -, two grooves are formed in the inner part of the support frame, and a roller is movably arranged in the grooves and abuts against the support rod. The bottom of the clamping rod is tapered. A metal filter screen, a gauze screen and an activated carbon filter screen are sequentially and fixedly arranged in the filter box from right to left. The arrangement of the grooves and the roller can reduce the friction between the support frame and the support rod under the rolling of the roller, so that the support rod is more easily slid on the support frame, and the filter box is more easily installed and disassembled. The bottom of the clamping rod is tapered, so that the area of the bottom of the clamping rod is reduced, and the clamping rod is more easily inserted into the clamping groove. The arrangement of the metal filter screen, the gauze screen and the activated carbon filter screen can improve the filtering effect of the filter box and further improve the air quality in the room.

[0028] In the embodiment, as shown in Figures -, a plurality of drain pipes are fixedly arranged in the filter box between the metal filter screen and the gauze screen. A collecting box is arranged below the filter box. Two support blocks matched with the support frames are fixedly arranged on both sides of the collecting box. Two electric guide rails are symmetrically fixedly arranged on one side of the filter box. A cleaning brush abutting against the metal filter screen is fixedly arranged between the two electric guide rails. When used in rainy days, rainwater can pass through the metal filter screen and enter the filter box, but is blocked by the gauze screen. Then, the rainwater in the filter box is discharged outward through the drain pipes and flows into the collecting box for collection, so that the rainwater is not accumulated in the filter box. The support frames and the support blocks are movably connected, so that the collecting box can be taken out from the bottom of the filter box, and the collected rainwater in the collecting box is easily cleaned. The electric guide rails and the cleaning brush are simultaneously started to drive the cleaning brush to move up and down, so that the dust and sundries attached to the outer side of the metal filter screen are cleaned to avoid blockage.

[0029] In the embodiment, as shown in Figures -, the working process of the fresh air dehumidification and heat recovery system is as follows:

[0030] The filter box is fixed by the clamping of the clamping rod and the clamping groove in the fixing mechanism. When disassembled, the clamping rod is pulled upward to be separated from the clamping groove. Then, the tooth plate is engaged with the tooth block on the clamping rod to fix the clamping rod and prevent it from falling. Then, the filter box can be taken off from the air inlet and the air outlet, so that the filter box is easily disassembled. The electric guide rails and the cleaning brush are simultaneously started to drive the cleaning brush to move up and down, so that the dust and sundries attached to the outer side of the metal filter screen are cleaned to avoid blockage.

[0031] In summary, in the embodiment, the fresh air dehumidification heat recovery system according to the embodiment can reduce the friction between the support frame and the support rod under the rolling of the roller, make the support rod more easily slide on the support frame, and more conveniently install and dismount the filter box. The bottom of the clamping rod is tapered, which can reduce the area of the bottom of the clamping rod and make it more easily inserted into the clamping groove. The metal filter screen, gauze and activated carbon filter screen can improve the filtering effect of the filter box, further improve the air quality entering the room. When used in rainy days, the rainwater can pass through the metal filter screen into the inside of the filter box, but be blocked and intercepted by the gauze. Then the rainwater in the filter box is discharged outward through the drain pipe and flows into the collecting box for collection, avoiding the accumulation of rainwater in the filter box. The support frame and the support block can support the collecting box, and the support frame and the support block are movably connected, so that the collecting box can be taken out from the bottom of the filter box, thereby conveniently cleaning the collected rainwater in the collecting box. The electric guide rail and the cleaning brush are simultaneously started to drive the cleaning brush to move up and down, so as to clean the dust and sundries attached to the outside of the metal filter screen, avoiding blockage.
