It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0030] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0031] like Figure 1-Figure 5 As shown, the utility model provides a filter cavity with fixed protection, including a filter cavity 1, a partition 2 is installed inside the filter cavity 1, a communication slot 3 is opened on the surface of the partition 2, a resonance rod 4 is installed inside the filter cavity 1, and a fine-tuning device 5 is provided on the surface of the filter cavity 1.

[0032] The specific setting and function of the fine-tuning device 5 will be described in detail below.

[0033] like Figure 2-Figure 5As shown, the fine-tuning device 5 includes two limit plates 501, both of which are fixedly connected to the filter chamber 1, and a first screw rod 502 is fixedly connected to the surface of the limit plate 501, and a screw ring handle 503 is threadedly connected to the arc surface of the first screw rod 502, and a second screw rod 504 is threadedly connected to the inner wall of the screw ring handle 503, and one end of the second screw rod 504 is fixedly connected to a fixed plate 505, and a protective shell 506 is fixedly connected to the surface of the fixed plate 505. The interior of the protective shell 506 is fixedly connected to a plurality of springs 507, and one end of the plurality of springs 507 is fixedly connected to a buffer plate 508, and the buffer plate 508 is fixedly connected to the inner wall of the buffer plate 508. The surface is fixedly connected with a pad 509, which is a rubber plate. The buffer plate 508 will drive the pad 509 to move. At this time, the pad 509 made of rubber material can increase the friction between the buffer plate 508 and the filter chamber 1 to prevent the filter chamber 1 from shaking. The surface of the protective shell 506 is fixedly connected with four foot sleeves 510. The four foot sleeves 510 are all slidably connected to the filter chamber 1. The filter chamber 1 will move along the surface of the foot sleeves 510. At this time, the four foot sleeves 510 can protect the corners of the filter chamber 1. The surface of the foot sleeves 510 is rotatably connected with a number of balls 511, and the balls 511 are evenly distributed On the surface of the foot cover 510, the filter chamber 1 will drive the ball 511 to rotate along the surface of the foot cover 510. At this time, the ball 511 can reduce the friction between the foot cover 510 and the filter chamber 1. The surface of the screw ring 503 is fixedly connected to two baffles 512. Both baffles 512 are stainless steel plates. The screw ring 503 will drive the two baffles 512 to rotate. At this time, the baffles 512 can place the first screw rod 502 and the second screw rod 504 from the two ends of the screw ring 503. The arc surface of the screw ring 503 is fixedly connected to the friction sleeve 513. The arc surface of the friction sleeve 513 is fixedly connected to several convex The strip 514 is used to rotate the friction sleeves 513 on the two screw ring handles 503 at the same time, and then the friction sleeves 513 will drive the screw ring handles 503 to rotate. At this time, the friction sleeves 513 and the convex strips 514 can increase the friction between the operator's fingers and the screw ring handles 503. A plurality of damping rods 515 are fixedly connected to the surface of the protective shell 506. The plurality of damping rods 515 are fixedly connected to the buffer plate 508. The damping rod 515 is adapted to the size of the spring 507. The buffer plate 508 will drive one end of the damping rod 515 to move. At this time, the damping rod 515 can prevent the spring 507 from jumping repeatedly.

[0034] The overall working principle is that when there is a small tilt deviation on the placement surface of the filter chamber 1, the friction sleeves 513 on the two screw ring handles 503 can be rotated at the same time, and then the friction sleeves 513 will drive the screw ring handles 503 to rotate. At this time, the friction sleeves 513 and the ridges 514 can increase the friction between the operator's fingers and the screw ring handles 503, and then the screw ring handles 503 will drive the first screw rod 502 and the second screw rod 504 to move away from each other. At the same time, the screw ring handles 503 will drive the two baffles 512 to rotate. At this time, the baffles 512 can place the first screw rod 502 and the second screw rod 504. The two ends of the screw ring 503 are separated, and then the first screw rod 502 will drive the limit plate 501 to move. At this time, the limit plate 501 will drive the filter chamber 1 to move. At the same time, the second screw rod 504 will drive the fixed plate 505 to move. Then the fixed plate 505 will drive the protective shell 506 to move. At this time, the filter chamber 1 will move along the surface of the foot cover 510. At this time, the four foot covers 510 can protect the corners of the filter chamber 1. At the same time, the filter chamber 1 will drive the ball 511 to rotate along the surface of the foot cover 510. At this time, the ball 511 can reduce the friction between the foot cover 510 and the filter chamber 1. Then, when the filter chamber 1 When moving in the direction away from the protective shell 506, the spring 507 inside the protective shell 506 will use its own elastic force to move the buffer plate 508 along with the movement of the filter chamber 1, and then the buffer plate 508 will drive the pad 509 to move. At this time, the pad 509 made of rubber can increase the friction between the buffer plate 508 and the filter chamber 1 to prevent the filter chamber 1 from shaking. At the same time, the buffer plate 508 will drive one end of the damping rod 515 to move. At this time, the damping rod 515 can prevent the spring 507 from jumping repeatedly. When the filter chamber 1 is adjusted to a horizontal state, the rotation of the screw ring 507 can be stopped. 3. By setting up the fine-tuning device 5 and utilizing the mutual cooperation among the limiting plate 501, the first screw rod 502, the screw ring handle 503, the second screw rod 504, the fixing plate 505, the protective shell 506, the spring 507 and the buffer plate 508, the filter chamber 1 can be placed in a horizontal state when the prevention surface of the filter chamber 1 is slightly tilted. This avoids the situation in which, when the filter chamber 1 is installed, the placement surface of the filter chamber 1 is tilted due to environmental factors, causing errors in the transmission of the working components in the filter chamber 1, resulting in damage to the working components in the filter chamber 1. This improves the transmission stability of the working components and further improves the adaptability of the filter chamber 1.
