One end of the air vent slide bar 101 is in sliding fit with the outer surface of the mixing disk 205, and the other end of the air vent slide bar 101 is in sliding fit with the first air vent ball plug 102 slidably arranged inside the air vent housing 109. The first air vent ball plug 102 is arranged on the air vent housing 109 through the air vent return spring 103. The chamber inside the air vent housing 109 is communicated with the air vent connecting pipe 104. A second air vent ball plug 106 is slidably arranged inside the air vent connecting pipe 104, and an air vent spring 107 is arranged between the second air vent ball plug 106 and the air vent connecting pipe 104. An air vent connecting cylinder 105 is rotatably arranged on the air vent connecting pipe 104, and internal threads matching with the air vent connector 108 are arranged on the inner wall of the air vent connecting cylinder 105.

[0034] As shown Figures 1 to 12As shown, the filtering part 3 includes a filtering sliding cylinder 301, a first filter net 302, a second filter net 303, a filtering outer shell 304, a filtering water inlet 305, a filtering water drain 306, and a filtering exhaust pipe 307; a filtering water inlet 305 for water inlet is arranged at the top of the filtering outer shell 304, and a filtering water drain 306 for water drainage is arranged at the bottom of the filtering outer shell 304; solenoid valves are arranged on both the filtering water inlet 305 and the filtering water drain 306; the filtering sliding cylinder 301 is detachably arranged at the top of the filtering outer shell 304, and the first filter net 302 and the second filter net 303 are arranged inside the filtering sliding cylinder 301; a cross-shaped protrusion is arranged on the outer wall of the filtering sliding cylinder 301, and the cross-shaped protrusion is in sliding fit with the groove on the filtering outer shell 304. The filtering outer shell 304 is connected to the filtering exhaust pipe 307 by threads, and a through hole for gas circulation is arranged at the bottom of the filtering sliding cylinder 301.

[0035] As Figures 1 to 3 shown, the supporting part 4 includes a supporting base 401, a supporting cylinder 402, and a supporting slider 403; the supporting cylinder 402 is fixedly arranged on the supporting base 401, the output end of the supporting cylinder 402 is fixedly provided with the supporting slider 403, and the supporting slider 403 is slidably arranged on the supporting base 401.

[0036] As Figures 1 to 12 shown, for a bag mouth blowing device with a filtering function disclosed by the present utility model, its working principle is as follows: open the solenoid valve on the filtering water inlet 305, discharge an appropriate amount of water from the filtering water inlet 305 into the filtering outer shell 304. At the same time, connect the ventilation connector 108 to the air outlet end of the blowing device, and rotate the ventilation connection cylinder 105 so that the ventilation connector 108 is installed in an appropriate position.

[0037] The air blowing device starts to work. The pressure of the air pushes the air - passing balloon plug II 106, and conveys the air from the air - passing connector 108 along the air - passing connecting pipe 104 to the chamber on the air - passing outer shell 109. At this time, the air - passing slide rod 101 does not slide, and the air - passing balloon plug I 102 closes the channel formed by the air - passing outer shell 109 and the air - passing slide rod 101. Then, the driving motor is started. The driving motor rotates to drive the mixing connector 201. The mixing connector 201 drives the mixing disk 205, the mixing fan blades 203, and the mixing stirring ring 202 to swing around the center of the mixing disk 205. The swinging of the mixing disk 205 pushes the air - passing slide rod 101, causing the air - passing slide rod 101 to slide intermittently. The sliding of the air - passing slide rod 101 pushes the air - passing balloon plug I 102, making the channel formed by the air - passing outer shell 109 and the air - passing slide rod 101 open and close intermittently. At this time, the air in the chamber of the air - passing outer shell 109 is discharged into the filter outer shell 304 through the holes on the air - passing slide rod 101 from this channel. At this time, the swinging mixing fan blades 203, mixing disk 205, and mixing stirring ring 202 make the air entering the filter outer shell 304 mix fully with water, so that carbon dioxide, ammonia, hydrogen sulfide, ozone, and other large - particle impurities in the air dissolve into the water and are thus removed. The air treated by water enters the filter sliding cylinder 301 from the hole at the bottom of the filter sliding cylinder 301 at the top of the filter outer shell 304 and is filtered again by the first filter net 302 and the second filter net 303 to filter bacteria and microorganisms in the air. The air filtered twice is discharged from the filter exhaust pipe 307 to the bag - mouth to be blown at the support slider 403. Thus, the air is cleaned, and the quality of the produced products is guaranteed.

[0038] When maintenance is required, rotate the filter exhaust pipe 307 to disconnect the filter exhaust pipe 307 from the filter outer shell 304, remove the filter sliding cylinder 301, clean or replace the first filter net 302 and the second filter net 303 in the filter sliding cylinder 301, and then reinstall them after cleaning to complete the maintenance. When the water in the filter outer shell 304 becomes turbid, open the solenoid valve on the filter drain port 306 to drain the waste water, and then inject clean water from the filter water inlet 305 again to assist in air cleaning.
