Description

[0001] The present invention relates to the technical field of air purification, and in particular to a full-heat fresh air fan. Background Art

[0002] The fresh air purification system is an air treatment system that can introduce fresh outdoor air and exhaust dirty indoor air. Its core function is to realize the circulation exchange of indoor and outdoor air, thereby improving the indoor air quality. The fresh air system introduces outdoor fresh air through external vents or fans, and removes large particles, dust, pollen and other pollutants through filters. Some systems are also equipped with activated carbon filters or ultraviolet sterilization devices to remove bacteria, viruses and harmful gases. Some fresh air systems (such as full heat exchange fresh air systems) can recover heat or cold in the exhaust air during the ventilation process, reduce indoor temperature differences, and improve energy utilization efficiency. When the existing fresh air system exchanges outdoor air, when the outdoor wind is too strong, the outside cold air is easy to flow back into the room, causing the indoor air to drop, especially at night, when people are deep in sleep and cannot adjust the operation mode of the new hot air system in time, resulting in cold air flowing back into the room, causing people to become sick.

[0036] Specifically, by winding the wire 74 around the outside of the iron core 73, the iron core 73 can generate magnetic force when the wire 74 is energized, thereby adsorbing the magnetic block 77 to ensure the smooth flow of the second outdoor ventilation hole 105. The LED light can remind people that there is wind backflow, prompting people to check the pipeline.

[0037] In this embodiment, a connecting shell 76 is fixedly connected to the inner side of the outer shell 71, and a guide block 817 is slidably connected to the inner side of the connecting shell 76. The wire 74 is connected to the connecting shell 76 through the guide block 817. The connecting shell 76, the guide block 817 and the wire 74 are connected to the power supply 75 to form a closed loop. A slider 78 is fixedly connected to the outer side of the block 72. The slider 78 is slidably connected to the second outdoor ventilation hole 105. The front and rear ends of the slider 78 are fixedly connected to connecting blocks 79. Contacts are provided at the connection between the wire 74 and the connecting shell 76. The guide block 817 is a conductive structure.

[0038] Specifically, by adjusting the position of the guide block 817, the connection shell 76 is opened and closed, thereby achieving the closure of the wire 74, so that the first spring 710 can push the connection block 79 to make the stopper 72 block the second outdoor ventilation hole 105, thereby reducing the backflow of outdoor air.

[0039] In this embodiment, the power assembly 8 includes a fixed shell 81 fixedly connected to the chassis 1, the inner side of the fixed shell 81 is slidably connected with a first push shaft 82, the outer side of the first push shaft 82 is fixedly connected with a bent rod 813, the front end of the bent rod 813 is fixedly connected with a second push shaft 814, the front end of the second push shaft 814 is fixedly connected with an air block 815, the air block 815 is located on the inner side of the second outdoor ventilation hole 105, the upper end of the bent rod 813 is fixedly connected with an insertion shaft 816, the insertion shaft 816 is fixedly connected to the guide block 817, and the insertion shaft 816 is slidably connected to the chassis 1.

[0040] Specifically, the air block 815 can detect whether there is backflow wind, thereby controlling the movement of the guide block 817 to achieve the opening and closing of the second outdoor ventilation hole 105.

[0041] In this embodiment, the rear end of the first push shaft 82 is fixedly connected to the third sealing plate 86, and the third sealing plate 86 is located on the inner side of the fixed shell 81. A second spring 87 is arranged on the outer side of the first push shaft 82, and the front end of the second spring 87 is fixedly connected to the third sealing plate 86. The third sealing plate 86 is fixedly connected to the first push shaft 82. The rear end of the fixed shell 81 is fixedly connected to the air hole 88, and a sealing plug 89 is arranged on the inner side of the air hole 88. The rear end of the sealing plug 89 is fixedly connected to the compression shell 810, and a third spring 811 is arranged on the outer side of the air hole 88. The third spring 811 is fixedly connected to the compression shell 810, and a through hole 812 is opened at the front end of the sealing plug 89.

[0042] Specifically, the third spring 811 can pull the third sealing plate 86 so that the through hole 812 blocks the air hole 88. At this time, the air in the fixed shell 81 can only be discharged through the through hole 812, slowing down the rebound speed of the third sealing plate 86, thereby preventing the first push shaft 82 from rebounding rapidly and ensuring the stability of the connecting shaft 91.

[0043] In this embodiment, the control component 9 includes a connecting shaft 91 rotatably connected to the inner side of the fourth air chamber 204, one end of the connecting shaft 91 extends to the inner side of the third air chamber 203, the front end of the connecting shaft 91 is fixedly connected to a fixing rod 92, one end of the fixing rod 92 is fixedly connected to a wind housing 93, the wind housing 93 is a semicircular shell, an isolation chamber 14 is provided on the inner side of the control switch 10, the outer side of the rotating shaft 13 is rotatably connected to a rotating shell 95, the rotating shell 95 is located on the inner side of the isolation chamber 14, a worm gear 96 is provided on the outer side of the rotating shell 95, the rear end of the connecting shaft 91 is fixedly connected to a worm 94, the worm 94 is meshed with the worm gear 96, the inner side of the rotating shell 95 is fixedly connected to a first baffle 97, the outer side of the rotating shaft 13 is fixedly connected to a second baffle 98, and the second baffle 98 is located on the inner side of the rotating shaft 13.

[0044] Specifically, the rotation of the connecting shaft 91 can cause the worm 94 to drive the worm wheel 96 to rotate. When the first baffle 97 and the second baffle 98 are in close contact, the rotating shaft 13 will rotate with the connecting shaft 91 to make the control switch 10 block the first outdoor vent 104, switching the outdoor circulation to the indoor circulation mode.

[0045] In this embodiment, the rear end of the first push shaft 82 is fixedly connected to a tilted rod 83 , the rear end of the tilted rod 83 is fixedly connected to a clamping arc 84 , the outer side of the connecting shaft 91 is fixedly connected to a gear 85 , and the gear 85 meshes with the clamping arc 84 .

[0046] Specifically, the gear 85 can be locked by the locking arc 84 to prevent the connecting shaft 91 from rotating in the outdoor circulation mode.

[0047] Working principle: When the device is used, the motor is used to drive the rotating shaft 13 to rotate, so that one end of the control switch 10 is in contact with the second sealing plate 12, and the other end is in contact with the cushion block. At this time, it is in outdoor circulation mode. The outdoor air enters the first outdoor vent 104, exchanges heat through the full heat exchange core 3, and is filtered through the sterilization module 6, and then enters the room through the first indoor vent 101. The indoor air is sucked into the inner side of the second air chamber 202 through the second indoor vent 102, and then exchanges heat through the full heat exchange core 3 and passes through the second outdoor vent. The air is discharged through the air hole 105, and the control switch 10 is adjusted to cover the first outdoor vent 104. At this time, the third indoor vent 103 sucks indoor air and discharges it through the first indoor vent 101 after heat exchange through the full heat exchange core 3, thereby realizing indoor circulation. Under the outdoor circulation condition, once wind flows back into the inner side of the fourth air chamber 204 through the second outdoor vent 105, the wind will blow the air block 815 to make the second push shaft 814 push the bent rod 813 to move, and the plug shaft 816 will move the guide block 817 from the inner side of the connecting shell 76. The first spring 710 pushes the slider 78 to slide and the second outdoor vent 105 is blocked by the slider 72. At the same time, the bent rod 813 drives the first push shaft 82 to move backward and pulls the third sealing plate 86 to move. At this time, the inclined rod 83 drives the arc 84 to separate from the gear 85. At this time, the wind housing 93 drives the connecting shaft 91 to rotate under the action of the backflow wind, so that the worm 94 drives the worm wheel 96 to rotate. When the first baffle 97 and the second baffle 98 are close to each other, the rotation The shaft 13 will rotate along with the connecting shaft 91 to make the control switch 10 block the first outdoor vent 104, switching the outdoor circulation to the indoor circulation mode. When the second outdoor vent 105 is blocked, the second spring 87 will push the third sealing plate 86 to rebound. At this time, the third spring 811 will pull the third sealing plate 86 to make the through hole 812 block the air hole 88. At this time, the air in the fixed shell 81 can only be discharged through the through hole 812, slowing down the rebound speed of the third sealing plate 86, thereby slowing down the speed at which the arc 84 jams the gear 85.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments.
