It should be noted that these and other figures are given by way of example only and are not drawn to scale, and should not be construed as limiting the scope of the invention as it is actually claimed.

As shown in fig. 1 and 2, the fresh air system with sterilization function includes a housing 5, an air inlet 6, an air outlet 7 and a fan assembly 8. The shell 5 comprises an upper plane 51 and a lower plane 52, the air inlet 6 is located at one end of the shell 5 and used for introducing fresh air, and the air outlet 7 is located at the other end of the shell 5 and used for leading out air purified by a fresh air system. The fan assembly 8 provides power for extracting and sending out fresh air, the air outlet 7, the air inlet 6, the fan assembly 8 and the shell 5 jointly limit a fresh air flow guide channel, and the fresh air enters the shell 5 after being introduced by the air inlet 6 and then enters the fan assembly 8 and is conveyed to the external environment through the air outlet 7. The fresh air system also comprises a sterilization device 2 arranged in the fresh air diversion channel, and the sterilization device 2 can effectively remove bacteria and viruses in the fresh air and provide clean fresh air. The sterilisation apparatus 2 further comprises a power supply unit 9 for supplying power.

A preferred embodiment of the sterilization device 2 is to sterilize by releasing nano water ions, and as shown in fig. 3 and 4, the sterilization device 2 includes a discharge unit 21 and a cooling unit (not shown in the drawings), the cooling unit condenses part of the fresh air on the fresh air guide channel to form water, the discharge unit 21 ionizes the water on the cooling unit to generate nano water ions, and the nano water ions include hydroxyl (OH-) which carries negative electrons and can destroy proteins in contacted bacteria or viruses, so as to kill the bacteria or viruses in the air, thereby inhibiting and removing the bacteria or viruses in the air. Meanwhile, the hydroxyl is harmless to human bodies, so that the hydrogen can be used safely. Compare in traditional ultraviolet sterilization, nanometer water ion can follow the new trend and reach indoorly and be full of whole indoor space, can high-efficiently last disinfect to the room air, but ultraviolet sterilization need pass through irradiation time about 2 seconds, and the air flow velocity is very fast in the new trend system, therefore the efficiency of disinfecting is lower.

The nanometer water ions are released from an outlet 25 on the sterilizing device 2 and released to the external environment along with the fresh air in the fresh air guide channel. Certainly, the nanometer water ions directly contact with part of fresh air in the fresh air diversion channel to immediately generate a sterilization effect on the fresh air, and meanwhile, more nanometer water ions are continuously released into the indoor space, so that the sterilization effect on the indoor original air is realized.

The cooling unit of the sterilization device 2 condenses part of the fresh air into water drops which are gathered on a conductor plate, the discharge unit 21 applies high voltage to the upper part of the conductor plate gathered with the water drops, and the water drops on the conductor plate are quickly smashed, decomposed and ionized to generate nanometer water ions containing hydroxyl. The conductor plate is arranged in the sterilization device 2 and can be annular or rectangular; the discharge unit 21 may be selected from high voltage pins and arranged around the conductor plate in various arrangements, which will not be described herein.

The power supply unit 9 supplies the sterilizing device 2 with a suitable voltage required for discharging. In another embodiment, instead of providing a separate power supply unit 9, the sterilization device 2 may be connected to the main board, and the voltage supplied to the sterilization device 2 may be adjusted in time according to the voltage output from the main board. The sterilization device 2 is provided with a discharge unit 21 with multi-stage power, and can provide nano water ions with different concentrations to meet the requirements of fresh air release amount in different environments.

Fig. 5 and 6 show the distribution position of the fan assembly 8 in the housing 5, and the internal structure of the fan assembly 8 is visible from the air outlet 7. The fan assembly 8 is preferably a centrifugal fan assembly comprising an impeller 82, a volute 83 and a motor 84, the motor 84 being internal to the impeller 82 for powering the impeller 82, the volute 83 being housed externally of the impeller 82 and the motor 84. Fresh air enters the impeller space from the inlet collecting direction A of the fan assembly 8, then rotates along with the impeller 82 under the driving of the impeller 82, and finally leaves the fan assembly 8 along the radial outlet B in the radial direction. The radial outlet of the fan component 8 is directly connected with the air outlet 7 on the shell 5, so that fresh air is directly delivered to the indoor space after leaving the fan component 8. Centrifugal fan has the convulsions effect of preferred, and has the efficient impeller, and the bearing amplitude ratio is less, is fit for indoor use. The fan assembly 8 includes, but is not limited to, the above embodiments, and other fan models and arrangements may be used in other operating conditions.

The fan module 8 is preferably mounted in a manner that it is fixed to the lower plane 52 of the housing 5 by the motor fixing bracket 3, so that the inlet collecting direction a of the fan module 8 forms an angle with the plane direction of the upper plane 51 or the lower plane 52. As can be seen from fig. 2 and 6, the lower bottom surface 31 of the motor fixing bracket 3 is fixed on the lower plane 52 of the housing 5, and the upper inclined surface 32 of the motor fixing bracket 3 is fixedly connected with the fan assembly 8. The motor fixing support 3 is provided with a certain angle, so that the fan assembly 8 on the upper inclined plane 32 is obliquely arranged, a larger contact area can be provided for fresh air entering the shell 5, and the flow of introduced fresh air is increased.

Referring back to fig. 2, in addition to the above-mentioned embodiment, the sterilization device 2 is disposed between the air inlet 6 and the fan assembly 8, and is fixedly disposed on the inner wall surface of the housing 5. After the fresh air enters the fresh air diversion channel from the air inlet 6, the nano water ions generated on the sterilization device 2 are carried to enter the fan assembly 8 together, the kinetic energy is generated by the rotation of the impeller 82, and finally the kinetic energy is sent to the external environment through the air outlet 7, so that the sterilization effect is realized.

The fresh air system further comprises a filter device 10, and the filter device 10 is located between the air inlet 6 and the fan assembly 8, preferably near the air inlet 6. Because the new trend probably contains large granule impurity such as dust, consequently need be filtered the new trend by filter equipment 10 to purify the new trend. Filter equipment 10 includes multistage filter screen, and the filter screen can be glass fiber to detach 50 microns and bigger particulate matter, or choose for use one or more active carbon, utilize the adsorption efficiency adsorption capacity of active carbon particle 2 ~ 10 microns about impurity, or choose for use HEPA filter paper, filter air impurity etc. about 0.3 micron. The material of filter screen includes but not limited to above-mentioned material, according to new trend flow and filtration requirement select the material of suitable specification can.

In fig. 2, the filter device 10 includes a primary filter screen 11, an intermediate filter screen 12 and a high-level filter screen 13, which are sequentially distributed between the air inlet 6 and the fan assembly 8 along the fresh air diversion direction.
