[0018] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0019] Specific examples are given below.

The outlet 11 is adjusted upward and downward, and the storage plate 12 is moving. The designated rubber sheet 15 can slide on the inner wall of the limiting groove 14, and the position of the rubber sheet 15 leaking out is different according to the position of the outlet 11. After the outlet 11 is loosened, the position of the outlet 11 is initially fixed under the action of the reverse pulling force of the multiple sets of first elastic ropes 13 and the friction force, thereby completing the change of the airflow direction. Under the action of the two first elastic ropes 13, the rubber sheet 15 stored in the inner wall of the storage plate 12 is straightened. This step is combined with the setting of the outlet 11 that can be adjusted up and down, which can improve the flexibility of the airflow when it is discharged, and reduce the problem that the original outlet 11 is fixed, which makes it difficult to adapt to different working environments when used. At the same time, changing the position of the outlet 11 can improve the uniformity of the subsequent airflow distribution in the designated area, and under the action of the first elastic rope 13, reduce the problem of surface wrinkles of the rubber sheet 15 when it is stored.
[0021] like Figure 1-5As shown, two groups of brackets 2 are fixedly connected to the side wall of the bellows body 1; a motor 21 is installed on the top of one group of brackets 2; a reciprocating screw 22 is fixedly connected to the output end of the motor 21, and the reciprocating screw 22 is rotatably arranged in the middle of the two groups of brackets 2; a connecting piece 23 is threadedly connected to the middle of the reciprocating screw 22, and the end of the connecting piece 23 is fixedly connected to the side wall of the exhaust port 11; a support rod 24 is fixedly connected to the bottom of the connecting piece 23; a pressure plate 25 is fixedly connected to the end of the support rod 24, and the pressure plate 25 is arranged near the middle of the rubber plate 15; when working, the motor 21 is arranged on the outer wall of the bellows body 1, and under the action of the connecting piece 23 and the reciprocating screw 22, the fixed exhaust port 11 can be positioned. When the position of the exhaust port 11 needs to be continuously adjusted, the motor 21 switch can be started so that the reciprocating screw 22 can rotate while the connecting piece 23 can move up and down on its surface, and the position of the exhaust port 11 can be continuously adjusted. The provided pressing plate 25 can support the middle part of the unfolded rubber sheet 15. This step, in conjunction with the provided reciprocating screw 22, can further improve the stability of the exhaust port 11 when in use, and improve its flexibility at work after the up and down movement. In conjunction with the pressed pressing plate 25, the problem of the rubber sheet 15 bulging due to the influence of air pressure when gas passes through the exhaust port 11 and is discharged later can be reduced, thereby improving the stability of the rubber sheet 15 when blocking the airflow.
[0022] like Figure 1-5 As shown, the outer wall of the storage plate 12 is fixedly connected to two groups of shells 3; the inner wall of the exhaust port 11 is fixedly connected to two groups of second elastic ropes 31; the end of the second elastic rope 31 is fixedly connected to a sliding block 32, and the sliding block 32 is slidably arranged on the inner wall of the shell 3; the end of the sliding block 32 is fixedly connected to a first connecting rod 33; the end of the first connecting rod 33 is fixedly connected to a scraper 34, and the scraper 34 is slidably arranged in the middle of the exhaust port 11; during operation, by arranging the scraper 34 in the middle of the exhaust port 11, when the exhaust port 11 needs to be cleaned after long-term use, the staff can The two sets of sliding blocks 32 are pulled outward, and the length of the second elastic rope 31 is changed during the pulling process. At the same time, the scraper 34 can deeply scrape off the impurities accumulated on the inner wall of the exhaust port 11 and transfer them to the outside. After loosening the support for the two sets of sliding blocks 32, the sliding blocks 32 can be pulled in the opposite direction with the help of the second elastic rope 31 to reset their positions. This step, in conjunction with the scraper 34, can improve the cleanliness of the inner wall of the exhaust port 11 and reduce the problem of subsequent accumulation of impurities on the inner wall of the exhaust port 11 and the trouble of cleaning. In addition, under the action of the second elastic rope 31, the resetting work of the scraper 34 can be facilitated.
[0023] like Figure 1-5As shown, a connecting metal sheet 4 is fixedly connected to the middle of the exhaust port 11; two groups of rotating beads 41 are rotatably connected to the inner wall of the metal sheet 4; a second connecting rod 42 is fixedly connected to the middle of the rotating beads 41, and the second connecting rod 42 is arranged in an arc shape; a counterweight ball 43 is fixedly connected to the middle of the second connecting rod 42; during operation, by arranging two groups of counterweight balls 43 in the middle of the exhaust port 11, and under the influence of the air flow discharge, the counterweight ball 43 can be rotated until it hits the inner wall of the metal sheet 4, and continue to rotate and pass over the inner wall of the metal sheet 4, and this process is repeated. Under the action of the impact of the counterweight ball 43, this step can improve the cleanliness of other areas of the inner wall of the exhaust port 11, and fall to the position of the scraper 34 for subsequent cleaning.
[0024] like Figure 1-5 As shown, the end of the sliding block 32 is fixedly connected with a reinforcement 5; the top of the reinforcement 5 is fixedly connected with an air guide plate 51, and the air guide plate 51 is recessed inwardly; when working, the reinforcement 5 is provided on the side wall of the sliding block 32 to support the air guide plate 51, and when air flows through the exhaust port 11 later, the air flow can directly contact the recessed air guide plate 51 and push the sliding block 32 to slide outward, and then cooperate with the second elastic rope 31 to reset. In this step, under the action of the air guide plate 51, the scraper 34 can achieve a self-cleaning effect, reducing the problem of frequent pulling by subsequent staff.
[0025] like Figure 1-5 As shown, a sticky plate 6 is installed on the inner wall of the air guide plate 51; during operation, by setting the sticky plate 6 on the inner wall of the air guide plate 51, when the impurities are blown away after being scraped, some impurities can adhere to the middle of the sticky plate 6, and the sticky plate 6 can be torn off and replaced later. In this step, under the action of the sticky plate 6, some impurities in the airflow can be collected to reduce pollution to the working environment.
[0026] like Figure 1-5 As shown, the end of the pressing plate 25 is fixedly connected with a sliding piece 7, and the sliding piece 7 is arranged in contact with the outer wall of the rubber plate 15; during operation, by arranging the sliding piece 7 at the end of the pressing plate 25, the sliding piece 7 can directly contact with the surface of the rubber plate 15. In this step, under the action of the smooth sliding piece 7, the resistance and wear generated when contacting with the rubber plate 15 can be reduced.
[0027] like Figure 1-5 As shown, the inner wall of the limiting groove 14 is set in an arc shape; during operation, by setting the inner wall of the limiting groove 14 in an arc shape, the inner wall of the rubber sheet 15 directly contacts the arc-shaped limiting groove 14 when it is unfolded. This step, combined with the setting of the arc-shaped limiting groove 14, can reduce the wear on the inner wall of the rubber sheet 15 and increase the service life of the rubber sheet 15.
[0028] Working principle: After the bellows body 1 is installed in the designated working area, the fan switch inside the bellows body 1 can be started, and the treated gas can be discharged in cooperation with the exhaust port 11. Two groups of storage plates 12 are arranged in the middle of the bellows body 1. When the working position of the exhaust port 11 needs to be adjusted later, the exhaust port 11 can be held and moved up and down. During the movement of the storage plate 12, the designated rubber plate 15 can slide on the inner wall of the limiting groove 14, and the position of the rubber plate 15 leaking out can be different according to the different positions of the exhaust port 11. After the exhaust port 11 is released, the position of the exhaust port 11 can be adjusted in cooperation with the reverse pulling force of the multiple groups of first elastic ropes 13 and the friction force. The airflow direction is changed by performing a preliminary fixation, and the rubber sheet 15 stored in the inner wall of the storage plate 12 is straightened under the action of the two first elastic ropes 13. The motor 21 is arranged on the outer wall of the bellows body 1, and under the action of the connecting piece 23 and the reciprocating screw 22, the position of the fixed exhaust port 11 can be reinforced. When the position of the exhaust port 11 needs to be continuously adjusted, the motor 21 switch can be started, so that the connecting piece 23 can move up and down on its surface while the reciprocating screw 22 rotates, and the position of the exhaust port 11 is continuously adjusted. The pressure plate 25 can support the middle part of the unfolded rubber sheet 15. A scraper 34 is provided. When the exhaust port 11 needs to be cleaned after being used for a long time, the staff can pull the two sets of sliding blocks 32 outward, and change the length of the second elastic rope 31 during the pulling process. At the same time, the scraper 34 can deeply scrape the impurities accumulated on the inner wall of the exhaust port 11 and transfer them to the outside. After loosening the support for the two sets of sliding blocks 32, the sliding blocks 32 can be pulled in the opposite direction with the second elastic rope 31 to reset their positions. By providing two sets of counterweight balls 43 in the middle of the exhaust port 11, the counterweight balls 43 can rotate under the influence of airflow discharge until they hit the inner wall of the metal sheet 4, and continue to rotate and pass over the inner wall of the metal sheet 4, and repeat this process. By providing a counterweight ball 43 on the side wall of the sliding block 32 A reinforcement piece 5 is provided to support the air guide plate 51. When air flows through the exhaust port 11 later, the air flow can directly contact the sunken air guide plate 51 and push the sliding block 32 to expand and slide outward, and then reset in cooperation with the second elastic rope 31. A sticky plate 6 is provided on the inner wall of the air guide plate 51. When the scraped impurities are blown away, some impurities can adhere to the middle of the sticky plate 6. At the same time, the sticky plate 6 can be torn off and replaced later. A sliding piece 7 is provided at the end of the pressure plate 25, so that the sliding piece 7 can directly contact the surface of the rubber plate 15. The inner wall of the limiting groove 14 is set to an arc shape, so that when the rubber plate 15 is expanded, its inner wall can directly contact the arc-shaped limiting groove 14.
