Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 , an air outlet anti-clogging device comprises: a tube body 1, an end cover 2 is fixedly mounted on the tube body 1, a reset spring 4 is fixedly mounted on the lower end surface of the end cover 2, a steel ball 5 is also arranged inside the tube body 1, the steel ball 5 contacts the lower end of the reset spring 4, the inner cavity of the tube body 1 can be divided into a cylindrical inner cavity and a conical inner cavity, the minimum inner diameter of the cylindrical inner cavity is greater than the maximum outer diameter of the steel ball 5, and the steel ball 5 also contacts the conical surface inside the tube body 1; a thread is provided on the outer surface of the tube body 1, the tube body 1 is threadedly connected to the air chamber, and a circular hole is penetrated on the end cover 2, so that the overall structural design is more reasonable and can meet the actual use requirements.

[0023] The lower end surface of the tube body 1 is provided with a filter plate 6, and the lower end of the tube body 1 is also provided with an auxiliary component 3, which is also in contact with the filter plate 6. The auxiliary component 3 includes a movable ring 31, a connecting rod 32, a connecting seat 33, an L-shaped plug block 34 and an auxiliary spring 36. The movable ring 31 is rotatably arranged on the lower end surface of the tube body 1, and connecting seats 33 are movably arranged on both ends of the connecting rod 32. The connecting seat 33 is fixedly connected to the L-shaped plug block 34 or the movable ring 31. The L-shaped plug block 34 is slidably arranged on the tube body 1 and plugged into the filter plate 6. The two ends of the auxiliary spring 36 are respectively fixedly connected to the L-shaped plug block 34 and the tube body 1. The auxiliary component 3 also includes a slider 35, a guide block 37 and a connecting ring 38. The slider 35 is fixedly installed on the end surface of the L-shaped plug block 34, and the guide block 37 is fixedly installed on the lower end surface of the tube body 1. The guide block 37 is used In order to limit the direction in which the filter plate 6 is assembled on the tube body 1, the slot on the filter plate 6 for inserting the L-shaped plug 34 can cooperate with the L-shaped plug 34, avoiding the situation of adjusting the position of the filter plate 6 multiple times when the filter plate 6 is assembled, and further improving the use efficiency of the overall structure. The connecting ring 38 is arranged on the filter plate 6, and the inner surface and the outer surface of the connecting ring 38 are both provided with threads. The slider 35 is also slidably connected to the tube body 1, and the cross-sectional area of ​​the slider 35 is larger than the cross-sectional area of ​​the L-shaped plug 34. The slider 35 is used to limit the position of the L-shaped plug 34 on the tube body 1, which can enhance the stability of the sliding connection relationship between the L-shaped plug 34 and the tube body 1, thereby achieving the purpose of pre-establishing such structures. A knob is arranged on the outer surface of the movable ring 31, and an anti-slip groove is arranged on the knob to facilitate the actual operation of the user.

[0024] Working principle: the end cap 2 is fixed on the upper end of the tube body 1, and a hole is set through the end cap 2. The lower end of the reset spring 4 fixed on the end cap 2 contacts the steel ball 5. The steel ball 5 slides inside the tube body 1. The inner cavity of the tube body 1 can be divided into a cylindrical inner cavity and a conical inner cavity, and the minimum inner diameter of the cylindrical inner cavity is greater than the maximum outer diameter of the steel ball 5. Therefore, the thread at the upper end of the tube body 1 is used to tighten it from the bottom of the air chamber. After the air source of the air chamber is connected, the air source enters the bottom inlet of the tube body 1, and the wind pressure is overcome. The return spring 4 elastically pushes the steel ball 5 away, and the wind source blows into the upper part of the disc groove to the bottom of the tape. When the air source of the air chamber is closed, the return spring 4 elastically pushes the steel ball 5 to the orifice, and the steel ball 5 is in contact with the conical surface inside the tube body 1 to close the orifice to achieve a sealing effect. Before the airflow enters the interior of the tube body 1 from the lower end of the tube body 1, it will first be filtered by the filter plate 6 to remove the particulate matter contained in the airflow, thereby preventing the particulate matter from entering the inner cavity of the tube body 1 and affecting the airtightness between the steel ball 5 and the tube body 1.

[0025] When the filter plate 6 needs to be replaced or cleaned, the movable ring 31 movable at the bottom end of the tube body 1 is rotated, and the two ends of the connecting rod 32 are respectively movably connected to the connecting seat 33, and the connecting seat 33 is respectively set on the L-shaped plug block 34 and the movable ring 31. Therefore, after the movable ring 31 is rotated, the L-shaped plug block 34 will be pulled by the connecting rod 32 to slide in the direction away from the filter plate 6 until the L-shaped plug block 34 is separated from the filter plate 6. At this time, the filter plate 6 can be removed from the tube body 1 for cleaning or replacement, and the treated filter plate 6 is placed on the lower end surface of the tube body 1 along the guide block 37 fixed on the tube body 1. After loosening the movable ring 31, under the action of the auxiliary spring 36 fixedly connected to the L-shaped plug block 34 and the tube body 1 at both ends, the L-shaped plug block 34 slides toward the filter plate 6 and is inserted into the inside of the filter plate 6. Multiple L-shaped plug blocks 34 cooperate with each other to fix the position of the filter plate 6 on the lower end surface of the tube body 1.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
