[0018] Reference Figures 1 to 4 As shown, this utility model provides an automatic cleaning electric drain valve, including: a drain valve body 1 and a cleaning pipe fitting 2. The cleaning pipe fitting 2 is connected to the side end of the drain valve body 1 via a flange 12.

[0019] A timer controller 21 is fixed to the front end of the cleaning pipe fitting 2. A lifting chamber 22 is provided on the inner side of the upper end of the cleaning pipe fitting 2. A lifting frame 4 is attached to the inner wall of the lifting chamber 22. A first electric push rod 41 is connected to the upper end of the lifting frame 4. A limit rod 51 is slidably connected to the lower groove surface of the upper end of the lifting frame 4. A cleaning device 5 is welded to the lower end of the limit rod 51. A rinsing nozzle 57 is embedded in the outer surface of the cleaning device 5. A second electric push rod 53 is connected to the upper end of the cleaning device 5 through a drive plate 52.

[0020] When the automatic cleaning of the drain valve body 1 connected to the sewage pipeline is performed, the sewage supply is stopped. The lifting frame 4 pushes the cleaning device 5 down through the limit rod 51 and moves it out of the lifting chamber 22 of the cleaning pipe 2. The second electric push rod 53 drives the cleaning device 5 to move inside the cleaning device 5 through the drive plate 51. The timer controller 21 then starts the infusion pump installed on the surface of the high-pressure infusion pipe 56, so that the cleaning fluid is delivered into the chamber of the cleaning device 5. The flushing nozzle 57 on the outer end face of the cleaning device 5 flushes and removes the impurities on the inner wall of the drain valve body 1. The flushing liquid is discharged through the connected pipe. Finally, the lifting frame 4 and the cleaning device 5 are reset to start the sewage discharge operation.

[0021] In this embodiment, an electric actuator 11 is connected to the upper end of the drain valve body 1 via a valve stem, and a fluid channel 13 is provided inside the drain valve body 1; the fluid channel 13 is connected to the inner side of the cleaning pipe fitting 2.

[0023] In this embodiment, a waterproof rubber plug 42 is bonded to the lower end face of the lifting frame 4; and the waterproof rubber plug 42 is correspondingly fitted to the lower cavity opening of the lifting chamber 22.

[0024] As a preferred implementation, when the lifting frame 4 moves upward, the waterproof rubber plug 42 moves upward and blocks the lower opening of the lifting chamber 22, preventing sewage from entering the lifting chamber 22. Furthermore, the lifting of the lifting frame 4 and the left and right movement of the cleaning device 5 are both controlled by the timer controller 21, which facilitates the periodic automatic cleaning of the inner wall of the drain valve body 1.

[0025] In this embodiment, a high-pressure infusion tube 56 is connected to the right end of the cleaning device 5 via a connecting hose 54, and a liquid guiding cavity 55 is provided inside the cleaning device 5. The connecting hose 54 is connected to the flushing nozzle 57 through the liquid guiding cavity 55, and the flushing nozzle 57 is distributed in a ring at equal intervals on the outer end face of the cleaning device 5. A drive plate 52 is attached to the right cavity wall of the lifting chamber 22; and a limit rod 51 passes through the drive plate 52.

[0026] As a preferred embodiment, the high-pressure infusion pipe 56 facilitates the delivery of cleaning fluid to the liquid guiding chamber 55 of the cleaning device 5, and then sprays it out through the flushing nozzle 57 to flush the inner wall of the flushing nozzle 57. This facilitates the removal of sewage impurities attached to the inner wall of the drain valve body 1, making it convenient and easy to clean the inner wall of the electric drain valve and ensuring the long-term stable operation of the electric drain valve.
