The embodiment employs five positioning pin holes 212, but the number is not limited to five, and more or less positioning pin holes can be used, and the positioning pin holes can be designed according to actual production conditions.

The collector module 10 and the generator module 20 are cylindrical as a whole and can be installed in a circular pipe, so that the dust collecting device can adapt to the dust collecting work of the pipeline and overcome the defects of the existing dust collecting device.

Based on this collection dirt electrode, the embodiment of this application provides a collection dirt unit, including fan and above-mentioned collection dirt electrode, the motor of fan and first drum 112 coaxial setting just are located one side of keeping away from circular framework 21 of first drum 112, and the impeller of fan is just to the collection dirt wind channel. The dust collecting unit can be applied to the tubular air pipe for air purification by adopting the dust collecting electrode.

Please refer to fig. 2, wherein the fan is an axial fan 101 or a centrifugal fan 102. In the drawings, an impeller of the fan is mainly shown, and the motor is not directly shown, but the structure of the conventional axial flow fan 101, centrifugal fan 102, and the like may be referred to.

Referring to fig. 3, the end surface of each first pole piece 114 corresponds to the pole wire 231 of the wire winding 23. The hub-shaped circular frame 21 facilitates accurate winding of the wire 231 of the wire winding 23 into a spoke shape to ensure alignment with the corresponding first pole piece 114.

The end face of each first pole piece 114 corresponds to the pole wire 231 of the wire winding 23, and the distance between the end face of the first pole piece 114 and the pole wire 231 of the corresponding wire winding 23 is D₁(see fig. 4), the wire winding 23 is connected to the positive high voltage U of the high voltage generator₁+; the collector 11 is connected with a negative high voltage U₂-; repeller 13 grounded U₀(ii) a The potential difference between the filament winding 23 and the end face of the first pole piece 114 and the distance D₁The relationship of (a) is defined as: U/D₁Less than 10^{^}7V/M。

In the present embodiment, the first pole piece 114 and the second pole piece 134 are inserted into each other without contacting each other. The voltage difference between the first pole piece 114 and the second pole piece 134 forms an electric field, and the positively charged particles are deflected toward the first pole piece 114 by the electric field force of the collector module 10 and collected by the negatively charged first pole piece 114.

Specifically, referring to fig. 5, a distance D between adjacent first and

second pole pieces

114 and 134 is shown₂The same everywhere;

alternatively, please refer to fig. 6, the distance D between the adjacent first and

second pole pieces

114 and 134₃Are not identical. And the distance D between the two₃Is gradually increased from the inside to the outside.

It is to be noted that D is as defined above₁、D₂、D₃Corresponding to D1, D2, D3 in fig. 4-6, the numbers are written as subscripts for convenience of textual description.

No matter what the spacing between the first pole piece 114 and the second pole piece 134 is, the dust collection requirement can be satisfied. For example, the distance between the two may be varied or varied, but it is sufficient if a dust collecting duct is formed and impurities such as positively charged dust can be adsorbed.

In the present embodiment, the inner diameter of the first cylinder 112 is greater than or equal to the outer diameter of the motor of the blower of the air cleaner. Because the inner diameter of the first cylinder 112 is larger than or equal to the outer diameter of the motor of the corresponding fan, the motor can not block the flow of wind, so that the wind can uniformly pass through the dust collecting air duct, and the dust collecting efficiency of the dust collecting air duct is improved.

In the present embodiment, the generator module 20 further includes a non-wind protrusion 25, and the non-wind protrusion 25 is provided at the center of the circular frame 21. The wind projections 25 can block the wind from passing through the middle so that the wind can flow only from the dust collection duct. Further, the size of the wind protrusion 25 corresponds to the diameter of the motor of the fan of the air cleaner.

Thus, referring to fig. 2, when the motor is working, the airflow enters from the generator module 20, because the middle of the motor is provided with the excessive wind protrusion 25, the airflow only gushes into the dust collecting air duct from the periphery of the excessive wind protrusion 25, and the outer diameter of the motor is not larger than the inner diameter of the first cylinder 112, so that the airflow is not blocked by the motor when flowing. The entire dust collecting duct can be completely flowed through by the air flow. During the flowing process, the dust and impurities with positive charges are adsorbed by the first polar plate.

The principle of the embodiment is as follows:

in the prior art, because of the basically square purification unit, the purification unit of the existing air purifier is not suitable for being installed in a round pipe, such as an exhaust pipe of a motor vehicle, a small round chimney and an exhaust flue, which cannot adopt the purification unit.

And further research finds that a general air purifier based on electrostatic dust collection is provided with a fan impeller to accelerate air passing, but because a motor driving the fan impeller can block air flow, a part of a collection unit of the existing purification unit does not pass air, the dust collection effect is lost, only other parts of the collection unit can collect dust, and the dust collection efficiency of the whole collection unit is greatly reduced.

The dust collecting electrode of the embodiment is integrally cylindrical, and is integrally cylindrical after the dust collecting unit is formed by combining the fan, so that the dust collecting electrode can be suitable for some circular-pipe ventilation pipelines, such as a vehicle-mounted air purifier. And to some naked air pipes, can follow square pipeline and replace to circular pipeline, conveniently arrange in building or device for air pipe's design is more diversified, also can give the better sense organ experience of user.

In practice, it has been found that for some square purification units, not only does no wind pass through the central part, but also no wind passes through the four corners or the wind volume is extremely small, which makes the utilization rate of the collection unit of such purification units lower.

The scheme of this application then can ensure all to have wind to pass through in the collection dirt wind channel, does not have the stopping of motor in the place that the air current flows through. And because do not block, the flow of wind can be more even, and the purification efficiency of every first pole piece 114 can keep unanimous, can further ensure that dust collection efficiency is higher.

In addition, the lengths of the first cylinder 112 and the second cylinder 132 can be increased according to the situation, the lengths of the corresponding pole pieces are also increased, and the dust collection efficiency is further improved.

To sum up, the dust collecting electrode of this application can be applied to the intraductal collection dirt that carries out through designing into cylindric with collector module 10, emergence utmost point module 20, satisfies the purification demand of the tuber pipe of corresponding type. After combining the fan and forming dust collecting unit, because the fan can not block that the air current flows, can make the whole air current that has in collection dirt wind channel flow through, the utilization ratio is promoted, improves dust collection efficiency.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
