[0049] refer to Figure 1 and Figure 2In a preferred embodiment, the sewage discharge device includes: a mounting part disposed on the mounting block 2 for mounting components; and a driving part disposed on the mounting part for providing power.
[0050] refer to Figure 2 and Figure 3 as well as Figure 4 In a preferred embodiment, the mounting part includes: a water inlet trough 8, which acts on the exhaust pipe 1 for sewage to enter; a mounting groove 9, which is disposed on the mounting block 2 for mounting the component; and a fixing seat 11, which is disposed on the mounting block 2 and fixedly connected to the mounting block 2.
[0051] refer to Figure 5 In a preferred embodiment, the driving unit includes: a drive motor 12, which is mounted on the fixed base 11 and fixedly connected to the fixed base 11; a screw rod 10, which is mounted in the mounting groove 9 and rotatably connected to the mounting groove 9; a first pulley 13, which is mounted on the output end of the drive motor 12 and fixedly connected to the output end of the drive motor 12; and a second pulley 14, which is mounted on the screw rod 10 and fixedly connected to the screw rod 10.
[0052] In this configuration, the slider 5 contains a drive assembly to provide power for moving the slider 5 along the slide rail 4; the first connector 7 and the second connector 17 can be connected via pipes to allow the water spray assembly 15 to supply water to the water sprayer 6; the first pulley 13 and the second pulley 14 are both made of stainless steel, which is not easily corroded and does not easily leave stains, and the first pulley 13 and the second pulley 14 are connected by a belt, which allows the first pulley 13 to rotate and the second pulley 14 to rotate.
[0053] refer to Figure 2 In a preferred embodiment, the exhaust gas treatment mechanism includes: a water spray assembly 15, which is mounted on and fixedly connected to the fixed base 11; multiple nozzles 16, which are mounted on the water spray assembly 15 for water spraying; and a second connector 17, which is mounted on and fixedly connected to the water spray assembly 15.
[0054] With this configuration, the water spray assembly 15 can be connected to an external water tank and can supply water to the spray nozzle 16 to operate; the nozzle 16 is used to uniformly spray water to filter the exhaust gas in the exhaust pipe 1.
[0055] This device, by incorporating a cleaning mechanism, can simultaneously clean the inner wall of the exhaust pipe 1 during exhaust gas cleaning, preventing stains from remaining inside the exhaust pipe 1 and ensuring its cleanliness. Furthermore, by incorporating an exhaust gas treatment mechanism, this device can uniformly spray water onto the exhaust gas, mixing impurities and harmful gases with the water to filter the exhaust gas.
[0056] Working principle: When in use, the exhaust gas enters the exhaust pipe 1. The exhaust gas entering the exhaust pipe 1 is supplied with water by the water spray assembly 15 to the nozzle 16, allowing the nozzle 16 to spray water to filter the exhaust gas in the exhaust pipe 1. Most of the dirt produced by the mixture of impurities and water enters the installation groove 9 through the water inlet 8 along the inner wall of the exhaust pipe 1. Then, the drive motor 12 drives the first pulley 13 to rotate. The first pulley 13 then drives the second pulley 14 to rotate through the belt. The second pulley 14 drives the screw rod 10 to rotate. When the screw rod 10 rotates, it moves the dirt in the installation groove 9 and discharges the dirt into the device. Meanwhile, some stains remain inside the exhaust pipe 1. These stains are connected to the first connector 7 and the second connector 17 through the pipe, allowing the water spray assembly 15 to supply water to the water sprayer 6. Then, by driving the slider 5, the slider 5 moves the water sprayer 6 along the slide rail 4. At the same time, the water spray assembly 15 sprays water to clean the inner wall of the exhaust pipe 1, washing away the remaining stains and sending them into the mounting groove 9, where they are discharged into the device by the screw rod 10.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
