[0020] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1 - 4 , the present invention provides a technical solution: a vacuum deaerator for reducing noise, including a storage bin 1, a vacuum pump 2 connected to one side of the storage bin 1, a discharge port 3 arranged inside the lower part of the storage bin 1, a sliding mechanism 4 arranged on the inner side above the storage bin 1, and an elastic mechanism 5 arranged on the upper surface of the storage bin 1;

[0022] The sliding mechanism 4 includes a first support plate 401 fixedly connected to the inner wall of the storage bin 1 near the vacuum pump 2. A first hole 402 is provided inside the first support plate 401. One end of the first support plate 401 away from the vacuum pump 2 is fixedly connected to a second support plate 403. A second hole 404 is provided inside the second support plate 403. A first sealing housing 405 is provided outside the vacuum pump 2. The first sealing housing 405 is fixedly connected to the storage bin 1. The first sealing housing 405 and the storage bin 1 are interconnected through a third hole 406. A sliding sealing gasket 407 is provided inside the first hole 402. The inner surface of the first hole 402 is in contact with the outer surface of the sliding sealing gasket 407. The outer appearance structure of the sliding sealing gasket 407 is a cuboid, so that the sliding sealing gasket 407 seals the inside of the first hole 402. The length and width of the sliding sealing gasket 407 are both greater than the length and width of the second hole 404, and the thickness of the sliding sealing gasket 407 is less than the length of the first hole 402, so that the sliding sealing gasket 407 can slide inside the first hole 402 but will not move outside the second hole 404. The central axis of the third hole 406 and the central axis of the second hole 404 are on the same straight line, and the central axis of the second hole 404 and the central axis of the first hole 402 are on the same straight line, so that air flows from the third hole 406 to the inside of the first hole 402 and then moves from the first hole 402 to the inside of the second hole 404.

[0023] The elastic mechanism 5 includes a second sealing housing 501 fixedly connected to the outer side above the storage bin 1. The second sealing housing 501 is communicated with the inside of the storage bin 1 through a fourth hole 502. A water inlet pipe 503 is communicated above the second sealing housing 501. The middle end of the water inlet pipe 503 is wound around the outside of the vacuum pump 2, so that the heat generated when the vacuum pump 2 works can be reduced at the water inlet pipe 503. A third support plate 504 is fixedly connected to the inner wall of the second sealing housing 501. A spring 505 is fixedly connected below the third support plate 504. The lower end of the spring 505 is fixedly connected to a baffle 506. A chute 507 is provided on the inner wall of the fourth hole 502. A slider 508 is provided inside the chute 507. The slider 508 is fixedly connected to the baffle 506. The lower end appearance structure of the baffle 506 is a rectangle, and one side of the upper surface of the baffle 506 away from the vacuum pump 2 is an inclined surface, so that the liquid inside the second sealing housing 501 can move from the hypotenuse of the baffle 506 to the inner wall of the storage bin 1. The central axis of the chute 507 is parallel to the central axis of the fourth hole 502, and the height of the chute 507 is greater than the height of the slider 508, so that the baffle 506 and the baffle 506 can slide vertically.

[0024] When the vacuum pump 2 is started, the air pressure inside the storage bin 1 decreases. The air pressure from the first sealing housing 405 to the sliding sealing gasket 407 is greater than the air pressure inside the storage bin 1. The sliding sealing gasket 407 is pushed, causing the air pressure from the first sealing housing 405 to the sliding sealing gasket 407 to decrease, resulting in a decrease in the air density from the first sealing housing 405 to the sliding sealing gasket 407. This reduces the sound transmission path during the operation of the vacuum pump 2, achieving the noise reduction efficiency.

[0025] When the air pressure inside the storage bin 1 decreases to the extent that the gas inside the liquid can be discharged, the vacuum pump 2 is then started to further decrease the air pressure inside the storage bin 1. The hydraulic pressure inside the second sealing housing 501 pushes the spring 505 and the baffle 506 downward to achieve feeding. When the air pressure inside the storage bin 1 returns to the air pressure inside the storage bin 1 again, the feeding stops. After waiting for a period of time for exhaust, the above process is repeated again. During this period, the middle end of the water inlet pipe 503 is wound around the outside of the vacuum pump 2, which can absorb the heat generated during the operation of the vacuum pump 2 and reduce the situation of damage caused by overheating of the vacuum pump 2.

[0026] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, article or device.
