Detailed Description
In order that the above-recited objects, features and advantages of the present utility model will become more readily apparent, a more particular description of the utility model will be rendered by reference to the appended drawings and appended detailed description.
In the traditional fresh air system, the pollutant filtering module can well filter out pollutants such as dust, aerosol and the like in the air, but the pollutant filtering module has poor capability of removing pollutants such as bacteria, fungi and viruses and the like, so that improvement of indoor air quality is limited.
Therefore, the utility model provides a corona sterilization type fresh air system which can effectively remove bacteria, fungi and viruses in the air, so that the indoor air quality is further improved.
As shown in fig. 1 to 3, the corona sterilization type fresh air system in the embodiment of the utility model comprises an air inlet main pipe 1, a corona purifying device 2, an air outlet main pipe 3 and a plurality of air outlet branch pipes 4, wherein:
the corona purifying device 2 is arranged indoors and at least comprises a shell 21, a fan module 22 and a corona purifying module 23, wherein an air inlet 211 and an air return opening 212 are formed in one end of the shell 21, an air outlet 213 is formed in the other end of the shell 21, the corona purifying module 23 is arranged in the shell 21 and located between the air inlet 211 and the air outlet 213, and the fan module 22 is arranged in the shell 21 and close to the air outlet 213.
The air inlet end of the air inlet main pipe 1 is arranged outdoors, and the air outlet end of the air inlet main pipe 1 is connected with the air inlet 211 of the shell 21. For example, the intake manifold 1 may be provided through a wall.
The air inlet end of the air outlet main pipe 3 is connected to the air outlet 213 of the shell 21, the air outlet main pipe 3 is provided with air outlet interfaces corresponding to the air outlet branch pipes 4 one by one, and each air outlet branch pipe 4 is connected to the corresponding air outlet interface. For example, each of the outlet branches 4 is provided in a separate room, and each of the outlet branches 4 is for performing fresh air supply to the corresponding room.
The working process of the corona sterilization type fresh air system in the embodiment of the utility model is as follows:
the fan module 22 is started, and the fan module 22 drives fresh air outdoors to flow into the shell 21 from the air inlet header pipe 1 and the air inlet 211. Of course, at this time, the indoor air may also flow into the housing 21 through the return air inlet 212.
Then, the air flows through the corona purifying module 23 under the driving of the fan module 22 and then flows into the air outlet header pipe 3 from the air outlet 213, and in the process, the corona purifying module 23 performs corona purification on the flowing air to kill bacteria, fungi and viruses in the air, so that the indoor air quality is improved.
After the purified air flows into the air outlet manifold 3, it is finally supplied to each corresponding position in the room, for example, each room, through each air outlet branch pipe 4.
Therefore, by arranging the corona purifying device 2 at the joint of the air inlet main pipe 1 and the air outlet main pipe 3, bacteria, fungi and viruses in indoor air can be effectively removed by the corona sterilizing type fresh air system, so that the indoor air quality is improved.
It should be noted that the air inlet 211 and the air return 212 of the housing 21 may be opened at the same time, or may be opened only one. When the air inlet 211 and the air return 212 are opened simultaneously, the corona sterilization type fresh air system in the embodiment of the utility model blows fresh air outdoors into a room and simultaneously performs circulating purification on the indoor air, thereby further improving the quality of the indoor air.
While when only the return air inlet 212 is opened, the corona sterilizing type fresh air system in the embodiment of the utility model only performs the circulating purification of the indoor air. For example, when the outdoor air quality is poor, only the return air port 212 may be opened in order to prevent the outdoor air from polluting the indoor environment.
As shown in fig. 1, optionally, a main air inlet electric valve 5 is arranged in the air inlet main pipe 1, and a main air outlet electric valve 6 is arranged in the air outlet main pipe 3.

When the main pipe air outlet electric valve 6 is completely closed, the corona sterilization type fresh air system in the embodiment of the utility model stops air supply.
By controlling the main air intake motor valve 5, the air volume of fresh air taken in from the outside can be controlled. When the intake electric valve 5 is completely closed, fresh air outside cannot enter the housing 21 through the intake 211. At this time, the circulation purification process for the indoor control can be performed only through the return air port 212.
As shown in fig. 1, optionally, the air inlet end of the air outlet branch pipe 4 is connected to the air outlet interface in a sealing way through a clamping piece 7, and a branch pipe air outlet electric valve 9 and a branch pipe air outlet fan 8 are arranged in the air outlet branch pipe 4.
By controlling the opening of the branch air outlet motor valve 9 and the power of the air outlet fan 8, flexible adjustment of the air quantity blown out from the air outlet branch pipe 4 can be implemented. When the branch air outlet motor valve 9 is completely closed, the air outlet branch pipe 4 stops air outlet.
As shown in fig. 3, optionally, the corona purifying device 2 further includes a filter module 24 in the housing 21 and close to the air inlet 211 and the air return 212, and after the air flows into the housing 21 through the air inlet 211 and/or the air return 212, the air flows through the filter module 24 and the corona purifying module 23 in sequence, where the filter module 24 is used for filtering the flowing air, so as to filter dust, aerosol and other pollutants in the air.
Optionally, in order to improve the filtering effect of the filtering module 24, the filtering module 24 includes a primary filter screen, an activated carbon filter screen, and a high-efficiency filter screen that are sequentially set. The air flows through the primary filter screen, the active carbon filter screen and the high-efficiency filter screen in sequence, so that the filtering effect on pollutants such as dust, aerosol and the like in the air is further improved from heat. Of course, since the subsequent corona purifying module 23 is also capable of adsorbing dust and aerosol, the filter module 24 may also include only a primary filter screen for cost and volume.
