The fresh air purifying machine is characterized in that air is introduced into the fresh air purifying machine from an air inlet 4 at the lower part through the power attraction of the fan assembly 1, and clean air is blown out from an air outlet 5 at the upper part of the fresh air purifying machine after the filtering of the air filtering net 3 and the silencing effect of the noise reduction sponge 2.
As shown in fig. 4, the air inlet 4 is disposed at a lower portion of the fresh air purifying machine, where a plurality of air inlets 4 may be disposed, and are respectively disposed on a plurality of wall surfaces of the machine body 7. For example, when the fresh air purifying machine is a rectangular parallelepiped, the air inlets 4 may be opened on four wall surfaces and a bottom surface. Therefore, the fresh air purifier can be arranged at any position of the ground, the corner, the wall, the shed roof and the like, is applicable to wider environments, and improves the application range.
Furthermore, in the linkage system provided by the invention, the air inlet of the fresh air purifier is provided with one air inlet, and the air inlet is communicated with the outdoor air, so that the fresh air purifier can filter the outdoor fresh air and then introduce the filtered air into a room.

Thus, the indoor occupied area of the linkage system provided by the invention can be effectively reduced.
The fan assembly 1 is a power component of the fresh air purifier and provides power for air flow in the fresh air purifier. The air guiding device 8 is arranged below the fan in the fan assembly 1, and air entering the lower part of the fresh air purifier is collected and introduced into the fan assembly 1 through the air guiding device 7.
As shown in fig. 4, the flow guiding device 8 protrudes downwards below the fan in the fan assembly 1 to form a spherical cambered surface 9, and a flow guiding surface is connected to the upper edge of the spherical cambered surface 9, and the flow guiding surface gradually bends downwards to extend to be basically close to the machine body 7, preferably, the flow guiding surface can guide all the air into the fan assembly 1.
The flow guiding surface is airtight, and the air flow gradually gathers in the middle of the flow guiding device 8 along the upward inclined flow guiding surface, namely, around the spherical cambered surface 9.
The spherical cambered surface 9 is of a net structure, and the meshes are larger, so that air collected at the spherical cambered surface can easily enter a hemispherical-like space in the spherical cambered surface through the meshes, thereby realizing the confluence of air without increasing the resistance of air flow; the collected air is drawn by the blower and rotates with the impeller.
In a preferred embodiment, as shown in fig. 6, the net structure in the spherical cambered surface 9 is composed of a plurality of concentric circles and spacers passing through the center of the circle and being emitted outwards.
Further, in the concentric circles of the spherical cambered surface 9, the diameter of the circle on the side far away from the air inlet 4 is smaller than the diameter of the same circle on the side close to the air inlet 4. In this way, the gas flow rate of the collected gas when it exits the spherical camber 9 can be increased.
Further, in the spherical cambered surface 9, the farther the concentric circles are from the center of the circle, the more the spacers separate the circular rings between the concentric circles, and the smaller the grid through which the gas flows.
This is because when the gas is collected to the spherical cambered surface 9 under the power of the blower, the flow rate and direction of the gas flow at different positions are different. The gas flow passes through a plurality of grids in the spherical cambered surface 9, the grids change the flow direction of the gas and flow according to the set direction in the spherical cambered surface 9. The grid with more numbers is arranged at the outermost end of the spherical cambered surface, so that the gas with irregular flow direction around the spherical cambered surface 9 can be separated and guided into a plurality of gas flows with the set flow direction, and the angle of changing the flow direction after the gas flows enter the spherical cambered surface 9 is reduced.
When the formed airflow with the flow velocity in all directions is converged in the hemispherical-like space in the spherical cambered surface, the airflows in all directions impact each other to influence, and the sound generated when the air airflow collides with the fan is reduced.
In the spherical cambered surface 9, the circular radius at the joint with the diversion surface is preferably 80-110mm, and the thickness of the spherical cambered surface 9 is preferably 30-45mm, so that the noise generated when the air enters the fan assembly 1 can be effectively reduced.
Preferably, a grid-shaped heating device can be further arranged above the fan and below the air filter screen 3 in the fan assembly 1, so that heat is emitted outwards when the heating device works, the air passing through the heating device is heated, the effect of heating the air is achieved, and a control system of the heating device is different from that of the fan, so that a user can freely select whether the heating device starts to work at any moment according to the needs of the user.
In the present invention, a noise reduction sponge 2 is creatively provided in the fan assembly 1 to further reduce noise generated by impact collision of the fan assembly 1 with air introduced therein.
As shown in fig. 4 or 5, noise reduction sponge 2 with the same height as the fan assembly 1 is arranged at the left side and the right side of the fan assembly 1; further, noise reduction sponge 2 which is equal to the fan assembly 1 in height is arranged around the fan assembly 1.
Preferably, a groove with the same height as the noise reduction sponge 2 is arranged on one surface of the noise reduction sponge 2, so that the cross section of the noise reduction sponge 2 is U-shaped; more preferably, the noise reduction sponge 2 is at the same height as the fan assembly 1, and the opening direction of the groove of the noise reduction sponge faces the fan assembly 1 and is vertically arranged outside the fan assembly 1.
In one embodiment, as shown in fig. 4, the noise reduction sponge 2 is respectively arranged on the left side and the right side of the fan assembly 1 when seen from the right rear of the using interface; or in another embodiment, the noise reduction sponge 2 can be respectively arranged around the fan assembly 1.
Thus, when the fan impeller in the fan assembly 1 rotates at a high speed, the air flow rotates with the impeller and spreads to the surroundings, thereby flowing into the U-like groove of the noise reduction sponge 2. Due to the structural limitation of the noise reduction sponge 2, air flow can only flow to the air filter screen 3 through the air outlet in the fan assembly 1.
At this time, the noise reduction sponge 2 arranged in the fan assembly 1 not only plays a role in reducing noise, but also plays a role in guiding flow, so that all air flows to the air filter screen 3.
The noise reduction sponge 2 is made of polyester sound absorption cotton, and has the advantages of low pulling resistance, low aging speed and excellent high and low temperature performance. For example, polyurethane sound absorbing cotton having a high degree of porosity may be used.
The noise-reducing sponge 2 has a sound absorption coefficient of 0.02-0.8, and can well eliminate noise when the fresh air machine works.
The air filter screen 3 filters and purifies the inflowing air, and when the contact area of air and the air filter screen 3 is relatively large, the efficiency of air filtration can be effectively improved, and the resistance of air flow can be reduced.
In general, the best filtering effect is achieved when the airflow direction is in vertical contact with the filter screen; however, the vertical contact causes an increase in air flow resistance, resulting in operating pressure to the power plant being set; but also generates a large noise in a full-face contact collision. The vertical arrangement not only causes a reduction in the air volume, but also causes a noise increase in the apparatus.
Therefore, in the fresh air purifying machine according to the present invention, it is preferable that the plurality of air filters 3 are inclined by 10 to 20 degrees.
For example, as shown in fig. 5, the number of the air screens 3 is 4, and the four air screens 3 are connected to each other to form an M shape. The air flow introduced from the fan assembly 1 at the lower part is further guided into two air flows, and the two air flows respectively enter the space below the M-shaped air filter screen 3. The front and rear ends of the air filter 3 are fixedly connected with the machine body 7, so that the air flowing in from the lower part can only pass through the air filter 3 and then be blown out.
Due to the power and wind pressure provided by the fan assembly 1, the air flow escapes from the M-shaped filter screen space to the outside of the M-shaped filter screen after the air flow passes through the filtering function of the air filter screen 3.
Further, the air filter 3 is not limited to the M shape, but may be a shape when a plurality of M are arranged side by side, similar to a wave shape.
The air screen 3 is preferably used after folding polypropylene, glass fiber or polytetrafluoroethylene material, more preferably the thickness of the air screen 3 is 30-50mm, for example 40mm.
The set inclination angle enables the air flow entering the filtering unit to form the specific angle with the air filter screen 3, enlarges the contact area between the air flow and the air filter screen 3, improves the filtering efficiency and increases the filtering treatment capacity; the angle of the air flow in contact with the air filter screen is reduced, and the noise is effectively reduced.
In order to increase the service life of the air filter 3 and the air filtration efficiency, a primary filter 6 may also be provided between the air inlet 4 and the fan assembly 1. The primary filter screen 6 may be arranged in the same manner as the air filter screen 3, and may be stacked by using a plurality of layers of filter screens.
When the primary filter screen 6 is stacked by using a plurality of layers of filter screens, the primary filter screen 6 can be made of polypropylene, glass fiber or polytetrafluoroethylene materials, and is preferably stacked by using polypropylene. The thickness of the primary filter screen 6 can be 10-50mm.
At the moment, the fresh air purifier provided by the invention has a good air purifying effect, and PM2.5 dust purifying efficiency can reach 99.99%.
In the fresh air purifying machine provided by the invention, the power of the fan assembly 1 is up to 30W, the filtering speed of the fan assembly can reach 300m 3/h at the highest, and 40-300m 3/h of fresh clean air is provided for a room.
It has been found that in the filter unit, the air flow introduced by the fan assembly 1 has a large volume and velocity, and a large noise is generated when the air flow is directly hit on the hard object of the body 7. It has also been found through the research that attaching a special noise reduction sponge 2 to the area through which the air flows can reduce noise, thereby achieving the noise reduction effect.
In the invention, a noise reduction sponge 2 with a groove is arranged on the periphery of a fan assembly 1 so as to reduce noise generated by air flow in the fan assembly; further, the invention is also provided with noise reduction sponges 2 on the left and right sides of the air screen 3, as shown in fig. 5.
The noise reduction sponge 2 is plate-shaped and is fixed on the inner side of the machine body 7. The air flowing out of the air filter screen 3 is directly beaten on the noise reduction sponge 2 at the left side and the right side of the air filter screen 3, and when the air flow contacts with the noise reduction sponge 2, little noise is generated; the gas then turns towards the outlet 5.
In a more preferred embodiment, a plate-like (sheet-like) noise-reducing sponge 2 is also provided above the air screen 3 on the inside of the top end of the body 7, except for the air outlet 5. In this way, when the gas striking the noise reduction sponge 2 on the side wall of the body 7 is turned to move toward the top end of the body 7, the striking noise of the gas flow with the top wall of the body 7 can be reduced.
The noise reduction sponge 2 is fixedly connected with the machine body 7, for example, the noise reduction sponge 7 can be fixed on the machine body 7 by means of gluing, drilling, planing, nailing and the like.
Preferably, the thickness of the plate-shaped (sheet-shaped) noise reduction sponge 2 on the left and right sides and above the air screen 3 is 8-15mm, more preferably 9-13mm, and the sound absorption and noise reduction effects are good.
The sponge noise-reducing fresh air purifier provided by the invention can effectively reduce noise, and researches show that the noise of the fresh air purifier in the prior art is generally 45-70dB, and the noise of the purifier provided by the invention is only 35-40dB, such as 38.6dB, so that the sponge noise-reducing fresh air purifier is very suitable for household use, work and office study.

The server (cloud) transmits the received fresh air purifier action command to the MCU in the air purifier control module again through the router (WiFi/local area network), the MCU receives the fresh air purifier action command data and then sends out an execution fresh air purifier command, the execution fresh air purifier command is transmitted to the air purifier action unit in the air purifier control module, and the air purifier action unit executes actions according to the execution fresh air purifier command, such as controlling the air purifier to perform upshift or downshift actions, as shown in fig. 3.
For example, when the PM2.5 dust sensor in the fresh air purifier measures that the PM2.5 content is 5-15 mug/m 3, a micro-processing unit in a control module of the fresh air purifier sends a power command of the fresh air purifier, and the power command of the fresh air purifier is to start the air purifier to a first gear;
when PM2.5 dust sensor in the fresh air purifier measures PM2.5 content to be 15.01-25 mug/m 3, a micro-processing unit in a control module of the fresh air purifier sends out a power command of the fresh air purifier, and the power command of the fresh air purifier is to start the air purifier to a second gear.
When the air purifier is started, the PM2.5 dust sensor in the air purifier control module arranged in the air purifier monitors the air quality in real time, detection data are transmitted to the MCU in the air purifier control module, and the MCU transmits the received detection data to the server (cloud) through the router (WiFi/local area network), as shown in fig. 3.
