The filter 1200 is arranged in the dust removal cavity 1110. The blowing assembly 1300 comprises at least one blowing member 1310, which is located in the dust removal cavity 1110. The blowing member 1310 comprises a gas cavity (not shown) and an air inlet 1311 and a blowing port 1312 in communication with the gas cavity. The air inlet 1311 is configured to communicate with a gas source (not shown). The blowing port 1312 is configured to face the filter 1200 to blow gas to the filter 1200.
[0035] In the embodiment, the dust removal cavity 1110 is arranged on the shell 1100, and the dust suction port 1120 and the exhaust port 1130 are in communication with the dust removal cavity 1110. A worker can connect the exhaust port 1130 with a suction device (not shown) and suck the air in the dust removal cavity 1110, so that a negative pressure is generated in the dust removal cavity 1110, and the dust on the object to be cleaned outside the shell 1100 is sucked into the dust removal cavity 1110 through the dust suction port 1120. The filter 1200 is arranged in the dust removal cavity 1110, so that the dust entering the dust removal cavity 1110 can be filtered, most of the dust is left in the dust removal cavity 1110, and the amount of dust contained in the gas leaving the dust removal cavity 1110 through the exhaust port 1130 is reduced. The air blowing member 1310 is arranged in the dust removal cavity 1110, the air blowing member 1310 includes an air cavity, and the air inlet 1311 and the air blowing port 1312 in communication with the air cavity. The air inlet 1311 is configured to be in communication with an air source, and the air blowing port 1312 is configured to be directed to the filter 1200 to blow air to the filter 1200. When the filter 1200 is blocked by dust, the air in the air source is blown to the filter 1200 through the air blowing port 1312, so that the dust in the filter 1200 is separated from the filter 1200, and the filter 1200 is cleaned, thereby ensuring the filtering effect of the filter 1200. In summary, the self-cleaning device 1000 in the embodiment can automatically clean the filter 1200 while filtering dust, and the whole process does not need manual intervention, and the cleaning efficiency of the filter 1200 is high.
[0036] Please refer to Figure 1 In some embodiments, the self-cleaning device 1000 further includes an on-off control valve (not shown) connected with the air inlet 1311.
[0037] In the embodiment, the on-off control valve is connected with the air inlet 1311 and is used to control the opening and closing of the air inlet 1311. When the exhaust port 1130 is connected with the suction device and the air in the dust removal cavity 1110 is sucked, a negative pressure is generated in the dust removal cavity 1110, the on-off control valve closes the air inlet 1311, the air blowing port 1312 stops blowing air to the filter 1200, the dust suction port 1120 sucks the dust on the object to be cleaned into the dust removal cavity 1110, the filter 1200 filters the dust entering the dust removal cavity 1110, and the amount of dust contained in the gas leaving the dust removal cavity 1110 through the exhaust port 1130 is reduced. When the filter 1200 is blocked by dust, the on-off control valve opens the air inlet 1311, the air in the air source enters the air cavity through the air inlet 1311 and is blown to the filter 1200 from the air blowing port 1312, and the dust in the filter 1200 is blown away from the filter 1200.
[0038] Please refer to Figure 1In some embodiments, the blowing member 1310 comprises a plurality of blowing ports 1312 arranged at intervals, each of the blowing ports 1312 being in communication with the air cavity.

[0040] Referring to Figure 1 In some embodiments, the blowing assembly 1300 comprises two blowing members 1310 arranged on opposite sides of the filter 1200.
[0041] In the embodiment, the two blowing members 1310 correspondingly blow air to opposite sides of the filter 1200 through the blowing ports 1312 of the blowing members 1310 to blow dust in the filter 1200 away from the filter 1200.
[0042] In some embodiments, the blowing assembly 1300 comprises a plurality of blowing members 1310 arranged around the outer periphery of the filter 1200 along the central axis of the filter 1200.
[0043] Referring to Figure 1 In some embodiments, each blowing member 1310 comprises a plurality of blowing ports 1312 arranged at intervals along a first direction, the first direction being arranged transversely to the arrangement direction of the two blowing members 1310.
[0044] In the embodiment, the blowing member 1310 is provided with a plurality of blowing ports 1312 arranged at intervals along the first direction, so that the blowing member 1310 can blow air to different regions on opposite sides of the filter 1200 in the first direction through different blowing ports 1312 to clean different regions on the filter 1200, thereby improving the cleaning effect of the blowing member 1310 on the filter 1200.
[0045] In some embodiments, the first direction is parallel to the central axis of the filter 1200.
[0046] Referring to Figure 1 In some embodiments, the blowing assembly 1300 comprises a driving member 1400 arranged in the housing 1100, the driving member 1400 being connected to the filter 1200 and configured to drive the filter 1200 to rotate about the central axis of the filter 1200.
[0047] In the embodiment, the driving member 1400 is connected with the filter 1200, the driving member 1400 drives the filter 1200 to rotate around the central axis of the filter 1200, and the filter 1200 generates centrifugal force during rotation. Under the action of the centrifugal force, the dust in the filter 1200 is thrown out of the filter 1200. In this process, the air blowing port 1312 of the air blowing member 1310 blows gas to the filter 1200, and the gas blown to the filter 1200 blows the dust thrown out of the filter 1200 away from the filter 1200.
[0048] Please refer to Figure 1 In some embodiments, the self-cleaning device 1000 comprises a controller 1500, which is arranged on the outer wall of the shell 1100 and is electrically connected with the driving member 1400.
[0049] In the embodiment, the controller 1500 is used to control the start and stop of the driving member 1400. When the exhaust port 1130 is connected with the suction device and the air in the dust removal cavity 1110 is sucked, a negative pressure is generated in the dust removal cavity 1110. At this time, the worker controls the driving member 1400 to stop driving through the controller 1500, so that the rotation of the filter 1200 is stopped. The dust suction port 1120 sucks the dust on the object to be cleaned into the dust removal cavity 1110, and the filter 1200 filters the dust entering the dust removal cavity 1110, so as to reduce the amount of dust contained in the gas leaving the dust removal cavity 1110 through the exhaust port 1130. When the filter 1200 is blocked by dust, the worker controls the driving member 1400 to start through the controller 1500, and the driving member 1400 drives the filter 1200 to rotate, so as to throw the dust out of the filter 1200 and complete the cleaning of the filter 1200.
[0050] Please refer to Figure 1 In some embodiments, the shell 1100 comprises a dust inlet cavity 1140, which is located on one side of the dust removal cavity 1110 and is in communication with the dust suction port 1120 and the dust removal cavity 1110.
[0051] In the embodiment, the worker connects the exhaust port 1130 with the suction device and sucks the air in the dust removal cavity 1110, so that a negative pressure is generated in the dust removal cavity 1110. The dust on the object to be cleaned outside the shell 1100 is sucked into the dust inlet cavity 1140 through the dust suction port 1120 under the action of the suction force, and then enters the dust removal cavity 1110 from the dust inlet cavity 1140. The dust entering the dust removal cavity 1110 is filtered by the filter 1200, and most of the dust remains in the dust removal cavity 1110. In this process, the gas sucked into the dust removal cavity 1110 together with the dust passes through the filter 1200 into the exhaust port 1130 and is discharged from the exhaust port 1130 and out of the shell 1100.
[0052] In some embodiments, the dust cavity 1140 is located at one side of the dust removal cavity 1110 in the first direction.
[0053] Please refer to Figure 1 In some embodiments, the shell 1100 comprises an exhaust cavity 1150, which is located at one side of the dust removal cavity 1110 away from the dust inlet cavity 1140, and which is in communication with the dust removal cavity 1110 and the exhaust port 1130.
[0054] In the embodiment, the gas containing dust sucked into the dust removal cavity 1110 first enters the exhaust cavity 1150 through the filter 1200, then enters the exhaust port 1130 from the exhaust cavity 1150, and finally leaves the shell 1100 from the exhaust port 1130.
[0055] The application also provides a laser film opening system (not shown), which comprises the aforementioned self-cleaning device 1000.
[0056] In the embodiment, by arranging the dust removal cavity 1110 on the shell 1100, and the dust suction port 1120 and the exhaust port 1130 in communication with the dust removal cavity 1110, the worker can connect the exhaust port 1130 with a suction device, and suck the air in the dust removal cavity 1110, so that a negative pressure is generated in the dust removal cavity 1110, thereby sucking the dust on the object to be cleaned outside the shell 1100 into the dust removal cavity 1110 through the dust suction port 1120; by arranging the filter 1200 in the dust removal cavity 1110, the dust entering the dust removal cavity 1110 can be filtered, most of the dust is left in the dust removal cavity 1110, and the amount of dust contained in the gas leaving the dust removal cavity 1110 through the exhaust port 1130 is reduced; by arranging the air blowing member 1310 in the dust removal cavity 1110, the air blowing member 1310 comprises an air cavity and an air inlet 1311 and an air blowing port 1312 in communication with the air cavity, the air inlet 1311 is used to communicate with an air source, and the air blowing port 1312 is configured to face the filter 1200 to blow air to the filter 1200, so that when the filter 1200 is blocked by dust, the air in the air source is blown to the filter 1200 through the air blowing port 1312, so that the dust in the filter 1200 leaves the filter 1200, thereby realizing cleaning of the filter 1200 and ensuring the filtering effect of the filter 1200.
