Specific embodiments

[0022] The technical solutions of the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Embodiment 1

[0023] As Figures 1 - 6 shown, an automatic drainer with high corrosion resistance proposed by the present utility model includes a water cup 3 and a cup cover 5. The cup cover 5 is installed on the upper surface of the water cup 3, and the cup cover 5 and the water cup 3 are connected by threads. A sealing ring 19 is provided at the top of the inner wall of the cup cover 5, and the sealing ring 19 is used for sealing between the cup cover 5 and the water cup 3. Anti-slip protrusions 4 are provided on the outer surface of the cup cover 5 and the outer surface of the water cup 3. When the cup cover 5 and the water cup 3 are rotated and separated, the anti-slip protrusions 4 can increase the friction force to facilitate the rotation and separation of the water cup 3 and the cup cover 5. A connecting pipe 6 is connected to the upper surface of the cup cover 5, and the connecting pipe 6 is connected to an air filter. Then, the water filtered by the air filter during operation enters the interior of the water cup 3 through the connecting pipe 6. A sealing pipe 2 is connected to the lower surface of the water cup 3, and the end of the sealing pipe 2 is connected to a reducing pipe 1, and the inner diameter of the reducing pipe 1 is larger than the inner diameter of the sealing pipe 2.

[0024] Inside the water cup 3, a floating ball 7 is arranged. A movable pipe 10 is connected to the outer surface of the floating ball 7, and the movable pipe 10 passes through the sealing pipe 2 and the reducing pipe 1. A sealing sleeve 11 is sleeved on the outer surface of the movable pipe 10, and the sealing sleeve 11 is located inside the sealing pipe 2. Annular protrusions 16 are arranged at both the upper and lower positions of the outer surface of the movable pipe 10 above the sealing sleeve 11. The two annular protrusions 16 play a role in limiting and fixing the sealing sleeve 11. A first through hole 12 is arranged on the outer surface of the sealing sleeve 11, and a second through hole 17 is arranged on the outer surface of the movable pipe 10, and the first through hole 12 and the second through hole 17 are communicated. A spiral spring 13 is sleeved on the outer surface of the movable pipe 10 at the position below the sealing sleeve 11, and the spiral spring 13 is located inside the reducing pipe 1. A retaining ring 15 is sleeved on the outer surface of the movable pipe 10 at the position below the spiral spring 13. The elastic force of the spiral spring 13 acts on the movable pipe 10 through the retaining ring 15. A clamping groove 18 is arranged on the outer surface of the movable pipe 10 at the position below the retaining ring 15. A snap ring 14 is installed inside the clamping groove 18. The snap ring 14 plays a role in limiting the retaining ring 15 and also facilitates the installation of the spiral spring 13 and the retaining ring 15.

[0025] When the utility model is in use, if the connecting pipe 6 is connected to the air filter, the water filtered out during the operation of the filter enters the water cup 3 through the connecting pipe 6. The water inside the water cup 3 causes the floating ball 7 to drive the movable pipe 10 to rise, and at the same time, the spiral spring 13 is compressed. When the first through hole 12 and the second through hole 17 enter the water cup 3, the accumulated water inside the water cup 3 enters the movable pipe 10 through the first through hole 12 and the second through hole 17 and is discharged. After the drainage is completed, the compressed spiral spring 13 causes the movable pipe 10 to drive the floating ball 7 to descend, and the first through hole 12 and the second through hole 17 enter the sealing pipe 2 and are sealed by the sealing sleeve 11. During the entire automatic drainage process, the spiral spring 13 does not contact the water inside the water cup 3, effectively avoiding rust and ensuring the sealing performance of the automatic drain, thereby improving the corrosion resistance and service life of the automatic drain.

A support ring 8 is arranged at a position close to the upper surface of the inner wall of the water cup 3, and a filter screen 9 is arranged on the upper surface of the support ring 8.

[0027] In this embodiment, the support ring 8 inside the water cup 3 and the pressing ring 20 inside the cup lid 5 are respectively in contact with the upper and lower surface edges of the filter net 9 to fix the filter net 9 inside the water cup 3. When water enters the water cup 3 through the communicating pipe 6, impurities in the water are filtered by the filter net 9 to avoid drainage blockage. When cleaning the filter net 9, rotate the cup lid 5 or the water cup 3 to separate the two, and then the filter net 9 can be taken out for cleaning.

[0028] The above specific embodiments are only several preferred embodiments of the present utility model. Based on the technical solution of the present utility model and the relevant inspirations of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
