The utility model achieves automatic discharge without on-duty, with a very low failure rate and guaranteed drainage safety. However, there are still areas that can be optimized.

[0004] The existing devices mainly control the discharge of condensed water through solenoid valves, which makes it difficult for some devices to control the limited sliding of the valve core according to the pressure difference between the inside of the water tank and the inside of the telescopic air pipe, resulting in the condensed water being inconvenient to automatically drain through the valve core. At the same time, some devices are difficult to adjust the position of the telescopic frame and the telescopic air pipe, which makes it inconvenient to adjust the air pressure range of the telescopic air pipe according to the air compression power, reducing the working efficiency and practicality of the device. Therefore, in order to solve the above problems, a pneumatic zero air consumption drainer is proposed. Utility Model Content

[0025] A drainage mechanism 2 is provided inside the transmission cylinder 14, and the drainage mechanism 2 includes a valve core 21. The interior of the valve core 21 is inserted into the inner wall of the drain valve 13, and the top of the valve core 21 passes through the top of the drain valve 13 and is fixedly connected to a telescopic frame 22. The inner wall of the telescopic frame 22 is fixedly connected to a telescopic air pipe 23. Through this design, the telescopic air pipe 23 drives the valve core 21 to limit the lifting and sliding through the telescopic frame 22. The front side of the top plate of the telescopic frame 22 is fixedly connected to an exhaust valve 24, and the rear side of the top plate of the telescopic frame 22 is fixedly connected to a one-way valve 25. The top of the one-way valve 25 is fixedly connected to a booster air pump 26. Through this design, the booster air pump 26 pressurizes the telescopic air pipe 23 through the one-way valve 25, and depressurizes the telescopic air pipe 23 through the exhaust valve 24.

[0026] An adjusting mechanism 3 is provided inside the adjusting box 15. The adjusting mechanism 3 includes a servo motor 31. The bottom of the servo motor 31 is fixedly connected to the middle of the top of the adjusting box 15. A transmission shaft 32 is fixedly connected to the middle of the bottom of the servo motor 31. The bottom end of the transmission shaft 32 passes through the adjusting box 15 and is fixedly connected to a first bevel gear 33. Through this design, the servo motor 31 drives the transmission shaft 32 and the first bevel gear 33 to rotate in a limited position. A second bevel gear 34 is meshed and connected below the first bevel gear 33. A transmission worm 35 is fixedly connected to the inner wall of the second bevel gear 34. Both ends of the transmission worm 35 are movably connected to the inner wall of the adjusting box 15. Through this design, the first bevel gear 3 is realized. The meshing of the second bevel gear 34 and the transmission worm 35 drives the limited rotation.

[0027] Working principle: When the water tank 11 needs to be drained at a constant pressure, the booster air pump 26 is first started through the control console 16.

The bottom plate of the telescopic frame 22 drives the valve core 21 to rotate synchronously. When the air pressure inside the water tank 11 is greater than the air pressure inside the telescopic air pipe 23, the condensate pushes the valve core 21 to slide upward, so that the condensate is discharged through the valve core 21 and the drain valve 13, thereby realizing the constant pressure drainage operation of the water tank 11.

[0028] When it is necessary to adjust the constant pressure range, first start the servo motor 31 through the console 16, the servo motor 31 drives the transmission shaft 32 to limit the rotation, the transmission shaft 32 drives the first bevel gear 33 to limit the rotation, the first bevel gear 33 engages to drive the second bevel gear 34 to rotate, the second bevel gear 34 drives the transmission worm 35 to limit the rotation, the transmission worm 35 engages to drive the transmission worm wheel 36 to rotate synchronously, the transmission worm wheel 36 drives the transmission screw 37 to limit the rotation, the transmission screw 37 drives the lifting screw barrel 38 to slide up and down, the lifting screw barrel 38 drives the telescopic frame 22, the telescopic air pipe 23 and the valve core 21 to slide synchronously, thereby realizing the adjustment operation of the constant pressure range, and the operation ends here.
