As shown in fig. 1-5, a fresh air machine self-cleaning filter element comprises a pipeline 1, a filter screen 103 is arranged in the pipeline 1, a housing 101 is arranged outside the pipeline 1, a connection port for connecting the pipeline 1 and the housing 101 is formed in the outer circumferential surface of the pipeline 1, the connection port is located right behind the filter screen 103 in the air flow direction, and the connection port is close to the filter screen 103.

The filter screen 103 is used for filtering dust particles and the like, and is not described in detail for realizing the prior filtering technology.

Be provided with clean component 2 in the housing 101, clean component 2 is used for carrying out flexible dust removal processing and dust removal in-process to filter screen 103, and fresh air machine can keep the operation.

In the existing fresh air fan technology, after the fresh air fan is used for a long time, the filter element is generally disassembled to remove dust and clean, the process is complicated, time and labor are wasted, the filter element is generally cleaned in a cleaning mode, and a person with insufficient experience easily breaks the filter element.

In this scheme, filter screen 103 is the filter core promptly, in this scheme utilization bernoulli's principle: the place with large flow velocity has small pressure, and negative pressure is formed near the filter screen 103, the dust on the filter screen 103 is blown away by the airflow formed by the negative pressure, and the dust is finally accumulated in the dust storage port 202 in the cleaning member 2, and in the dust removing process: 1. the adopted negative pressure air flow blowing mode is softer and cannot damage the filter screen 103; 2. during dust removal, the fresh air fan does not need to be stopped; 3. the dust removal is automatic, and the cleaning component 2 can be controlled to be opened periodically through a preset program to remove dust from the filter screen 103.

As shown in fig. 4-5, the cleaning member 2 comprises a stop 201 disposed within the housing 101, and a drive member is disposed within the housing 101 for driving the stop 201 to displace in a radial direction of the pipe 1.

Specifically, as shown in fig. 5, the driving member includes a sliding sleeve 204 disposed on the stopper 201 along the radial direction of the pipeline 1, a sliding rod 205 is slidably sleeved in the sliding sleeve 204, the sliding rod 205 is fixedly connected with the housing 101, and the stopper 201 is slidably disposed in the housing 101 through the cooperation between the sliding sleeve 204 and the sliding rod 205, and the sliding direction is the radial direction of the pipeline 1.

The casing 101 is further internally provided with a screw rod 206 axially parallel to the extending direction of the sliding sleeve 204, the screw rod 206 is in threaded connection with the stopper 201, the input end of the screw rod 206 is in power connection with a motor 207, the screw rod 206 is driven to rotate through the motor 207, and then the stopper 201 is pulled to move along the extending direction of the sliding sleeve 204, namely the radial direction of the pipeline 1.

As shown in fig. 4-5, a dust storage port 202 is opened on the side of the stopper 201 facing the filter screen 103, and a communication hole 203 for communicating the dust storage port 202 with the pipe 1 is provided on the stopper 201.

As shown in fig. 2-3, a cleaning opening is opened on the side of the casing 101 facing the opening of the dust storage opening 202, and a cover plate 102 is disposed in the cleaning opening.

The working principle of the utility model is as follows:

the motor 207 drives the screw rod 206 to rotate, so that the stopper 201 extends into the pipeline 1 along the extension direction of the sliding sleeve 204, namely along the radial direction of the pipeline 1, at the moment, a gap a is formed between the stopper 201 and the pipeline 1, airflow flows to the filter screen 103 through the gap a, and the opening of the dust storage port 202 is opposite to the filter screen 103;

when the air flow passes through the gap a, according to the bernoulli principle: the place with large flow velocity has small pressure, so negative pressure is formed between the dust storage port 202 and the gap a, the negative pressure causes the air in the dust storage port 202 to flow to the gap a through the communication hole 203, meanwhile, taking the view angle in fig. 3 as an example, because the air in the dust storage port 202 flows away, the air on the left side of the filter screen 103 will flow to the dust storage port 202 and the air flow direction at this time is opposite to the air flow direction of the fresh air fan in the pipeline 1, that is, when the air on the left side of the filter screen 103 flows to the dust storage port 202, the air attached to the filter screen 103 will be blown and pulled to the dust storage port 202, and because the diameter of the communication hole 203 is small, the dust is finally gathered in the dust storage port 202 to be temporarily stored;

after a preset time, the motor 207 rotates reversely to return the stopper 201 to the housing 101, and the cover plate 102 is opened to remove the dust in the dust storage port 202.

In the preferred embodiment, in order not to let dust leave the dust storage port 202 through the communication hole 203, the diameter of the communication hole 203 is set small, in order not to influence the communication between the dust storage port 202 and the pipe 1 by the diameter of the communication hole 203:

one is as follows: a plurality of groups of communication holes 203 are evenly arranged.

Secondly, the diameter of the communication hole 203 can be larger, and a filter plate is arranged in the communication hole 203, so that dust is prevented from leaving the dust storage port 202 by the filter plate.

Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the utility model as defined by the appended claims.
