Detailed Description

The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1-2, a fresh air machine integrating purification, dust removal and air exhaust comprises a casing 10, a fresh air system 11 disposed in the casing 10, and a dust removal mechanism 20 disposed at an outdoor air inlet end of the fresh air system 11, wherein the dust removal mechanism 20 is used for performing three-stage purification and dust removal treatment on outdoor air, so as to freshen the air entering the room and provide a good residential office environment for indoor users.

As shown in fig. 3, the dust removing mechanism 20 includes a primary cleaning member for performing primary dust removal processing on air, a secondary cleaning member for performing secondary dust removal processing on air, and a tertiary cleaning member for performing tertiary dust removal processing on air.

As shown in fig. 3, the primary cleaning member includes a dust removal duct 30, and the dust removal duct 20 is divided into two parts along its own axial direction: the filter plate is arranged at one end of the cylindrical section, the other end of the cylindrical section is connected and communicated with the large end of the circular truncated cone section, and the small end of the circular truncated cone section is provided with a connecting pipe a32 used for being connected and communicated with the secondary purification member.

The outdoor air is filtered by the filter sheet 31 into the dust removing duct 30 after large particles of dust are filtered, and then enters the secondary purification member through the connection pipe a 32.

As shown in fig. 3, the secondary purification member includes a cyclone separator 40, the cyclone separator 40 is used for receiving the air after the primary dust removal and performing a dust centrifugal separation process on the air, an air inlet end of the cyclone separator 40 is connected and communicated with a connecting pipe a32, an air outlet end is provided with a connecting pipe b42, a discharge port is provided with a dust collection drawer a41, and the cyclone separator 40 can be realized by the prior art.

The air after the first-stage dust removal enters the cyclone separator 40 through the connecting pipe a32, the cyclone separator 40 performs dust centrifugal separation treatment on the air, the treated air is discharged through the connecting pipe b42, and the dust is discharged through the discharge port and collected by the dust collection drawer a 41.

In the above process, since the dust removing pipeline 30 is composed of the cylindrical section and the circular truncated cone section, according to bernoulli's principle, the air flow velocity discharged through the circular truncated cone section is larger than the air flow velocity entering through the cylindrical section, that is, the air after the primary dust removal enters the cyclone separator 40 at a higher speed, and since the cyclone separator 40 separates the dust from the air in a high-speed centrifugal manner, the air enters the cyclone separator 40 at a higher speed, which is beneficial to increasing the rotating speed of the air, thereby improving the dust separating effect of the cyclone separator 40, that is, improving the effect of the secondary dust removal treatment;

above-mentioned in-process, collection bin a41 collects and stores the dust, the accessible arranges that the staff regularly takes out collection bin a41 and cleans the dust, if do not have collection bin a41, then the dust after being separated by cyclone 40 passes through the discharge gate and discharges, the dust after the discharge is located around new fan, a period of time, can lead to the dust content in the outdoor air inlet end ambient air of new fan to be higher than the normal value far away, increase the dust removal degree of difficulty, and influence subsequent new fan dust removal effect.

As shown in fig. 3-6, the three-stage purifying member includes a mounting shell 50, one side surface of the mounting shell 50 is provided with an air inlet 52, the other side surface is provided with an air outlet 53, an electrostatic adsorption component 54 is disposed in the mounting shell 50 and located between the air inlet 52 and the air outlet 53, and the electrostatic adsorption component 54 is used for performing dust removal treatment on air by adopting an electrostatic adsorption manner, which is realized by the prior art.

A speed-reducing bucket 43 is arranged between the air inlet hole 52 and the connecting pipe b42, the speed-reducing bucket 43 is in a circular truncated cone structure, the small end of the speed-reducing bucket 43 is communicated with the connecting pipe b42, and the large end of the speed-reducing bucket 43 is communicated with the air inlet hole 52.

The bottom of the mounting case 50 is provided with a dust collection drawer b 51.

The air after the secondary dust removal enters the mounting shell 50 through the connecting pipe b42, the retarding bucket 43 and the air inlet 52, the air is subjected to electrostatic adsorption dust through the electrostatic adsorption component 54, and then the air enters the fresh air system 11 through the air outlet 53 and further enters the indoor space.

In the above process, since the small end of the speed reducing hopper 43 is connected and communicated with the connecting pipe b42 and the large end is connected and communicated with the air inlet 52, according to bernoulli's principle, the air flow rate entering the mounting shell 50 is smaller than the air flow rate when the cyclone separator 40 discharges, and the air flow rate is an important influence factor of the dust removing performance of the electrostatic adsorption component 54, the slower the air flow rate, the better the dust adsorption effect, so the speed reducing hopper 43 is arranged between the mounting shell 50 and the cyclone separator 40;

in the process, the fresh air system 11 is closed, the electrostatic adsorption component 54 is powered off, dust can leave the electrostatic adsorption component 54 and fall into the dust collection drawer b51, a worker can be arranged to take out the dust collection drawer a41 regularly to clean the dust, and if the dust collection drawer b51 is not available, the dust concentration in the air is another important influence factor influencing the dust removal performance of the electrostatic adsorption component 54, after the air is used for a long time, the installation shell 50 is filled with the dust, the dust concentration is increased sharply, and the dust removal performance of the electrostatic adsorption component 54 is reduced.
