As shown in Figure 1-2, in order to solve the problem that the existing fresh air system cannot meet the needs of medical disinfection, the fresh air machine 1 of the present utility model (as shown in Figure 1) includes a casing 14, a fresh air channel 11 and an exhaust channel 12. The fresh air passage 11 and the exhaust air passage 12 are arranged in the casing 14, and a partition 13 is arranged between the fresh air passage 11 and the exhaust air passage 12. Both ends of the fresh air channel 11 are provided with a fresh air inlet 11a and a fresh air outlet 11b, between the fresh air inlet 11a and the fresh air outlet 11b, a first filter assembly 111, a fresh air blower 112 and a first sterilizing assembly 113 are arranged in sequence, and the exhaust air Both ends of the channel 12 are provided with an exhaust air inlet 12a and an exhaust air outlet 12b, and an exhaust fan 122, a second sterilization assembly 123 and a second filter assembly 121 are arranged in sequence between the exhaust air inlet 12a and the exhaust air outlet 12b , and at the same time spread the second filter assembly 121 all over the exhaust air outlet 12b. In addition, in order to prevent the fresh air blower 1 from generating noise during operation, sound-absorbing cotton (not shown in the figure) is provided in the housing 14 . Preferably, the first filter assembly 111 and the second filter assembly 121 are set as H13 grade high efficiency filter screens.

The above settings can meet the requirements of sterilization and disinfection of the fresh air machine 1. The fresh air channel 11 of the fresh air machine 1 is provided with a first filter assembly 111, a fresh air fan 112 and a first sterilization assembly 113 in sequence. The first filter assembly 111 is set as H13 high-efficiency filtration Its total filtering efficiency can reach 99.95%. After the outdoor air enters the fresh air channel 11, it first passes through the first filter assembly 111, and the first filter assembly 111 filters most of the particles in the air. , the air continues to flow forward and is driven by the fresh air blower 112 to the first sterilizing assembly 113. The first sterilizing assembly 113 sterilizes the air and finally forms clean and healthy fresh air. At this time, the fresh air enters the room from the fresh air inlet 11a. And exhaust the dirty air to the outside. The discharge process of indoor air is that the dirty air in the room enters the exhaust duct 3 through the exhaust air inlet 12a, and through the action of the exhaust fan 122, the dirty air is sterilized by the second sterilizing component 123, and then continues to the outdoor direction. After being filtered by the second filter assembly 121 at the exhaust air outlet 12b, it is discharged, and the air discharged to the outside is clean air. In order to avoid the existence of unfiltered air discharged to the outside, the second filter assembly 121 is placed The entire exhaust air outlet 12b is covered. The above process can effectively prevent dust, PM2.5 particles and some bacteria in the outdoor air from entering the room, and at the same time prevent the dirty air from being discharged outside without treatment to pollute the outside. The condition of the air.

Taking the fresh air machine 1 applied to the medical isolation cabin as an example, in order to meet the needs of medical disinfection in the medical isolation cabin, the first sterilizing component 113 can be set as a photoplasma device for sterilization, and the sterilization and disinfection through it will not produce any damage in the fresh air. Ozone can effectively and safely sterilize and disinfect the fresh air in the fresh air channel 11, ensuring the safety of the air entering the room. The second sterilizing component 123 can be set as a UV+ozone generating module to destroy bacteria molecules through the UV+ozone generating module structure, and cause the death of bacteria to achieve bactericidal effect. At the same time, through the UV+ozone generating module and the H13 high-efficiency filter screen, the air discharged from the medical isolation cabin can be purified to meet the needs of medical sterilization and disinfection. At the same time, the fresh air fan 1 of the utility model has a two-way flow and the fresh air channel 11 and the exhaust air channel 12 are not connected, which effectively avoids the mutual pollution of indoor and outdoor air, thereby further improving the effect of sterilization. In addition, since the medical isolation cabin needs to form indoor negative pressure, the rotation speed of the exhaust fan 122 is greater than the rotation speed of the fresh air fan 112 .

It should be noted that the fresh air blower 1 of the present utility model can be applied to ordinary rooms, and can also be applied to medical isolation cabins. Inside the medical isolation cabin. In addition, the rotation speeds of the fresh air fan 112 and the exhaust fan 122 of the present utility model are also set according to the needs of those skilled in the art and users. When positive pressure is required, the rotating speed of the fresh air fan 112 is greater than that of the exhaust fan 122, which is within the protection scope of the present utility model.

It should also be noted that the first sterilizing component 113 and the second sterilizing component 123 of the present functional utility model can be set according to the needs of those skilled in the art. In addition to being set as a photoplasm device and a UV+ozone generating module, it can also be set as Other sterilizing components, as long as the first sterilizing component 113 and the second sterilizing component 123 can meet the requirements of sterilizing and sterilizing, the utility model does not limit it, therefore, the above are all within the protection scope of the utility model. In addition, the first filter assembly 111 and the second filter assembly 121 can also be set according to the needs of those skilled in the art and users, and are not limited to the above-mentioned H13 advanced filter screen. Therefore, the above are also included in the utility model. within the scope of protection.

As shown in FIG. 2 , the utility model also provides a fresh air system, which has the fresh air blower 1 in any one of the above-mentioned embodiments. The fresh air system also includes a fresh air duct 2 and an exhaust duct 3, the fresh air duct 2 is connected to the fresh air outlet 11b, and the fresh air duct 2 is provided with an air inlet 21, and the exhaust duct 3 is connected to the exhaust air inlet 12a. The air duct 3 is provided with an air outlet 31 . Silencers 4 are arranged between the fresh air duct 2 and the fresh air outlet 11b, and between the exhaust duct 3 and the exhaust air inlet 12a, so as to reduce the transmission of noise. Both the fresh air duct 2 and the exhaust duct 3 are made of PVC. In general, the PVC used for the exhaust duct 3 and the fresh air duct 2 is hard PVC. The hard PVC used as the fresh air duct 2 and the exhaust duct 3 not only has good toughness and is non-toxic. And it has a long service life.

The fresh air system of the present utility model includes a fresh air fan 1, a fresh air duct 2 and an exhaust duct 3 connected to the fresh air fan 1, the fresh air duct 2 is connected to the fresh air outlet 11b, and the fresh air processed by the fresh air fan 1 enters the fresh air duct from the fresh air passage 11 2. Afterwards, it is exhausted into the room, and the dirty air in the room enters the exhaust channel 12 through the exhaust duct 3 to be discharged to the outside. In order to ensure the efficiency of fresh air and exhaust air, the fresh air duct 2 is arranged on the upper part of the room. The exhaust duct 3 is arranged at the bottom of the room. At this time, the fresh air moves from top to bottom to cover the entire indoor space, while the dirty air is directly discharged from the bottom to the outside, ensuring the ventilation efficiency of the room.
