[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0019] See also Figure 1-4 A sewage treatment device comprises a housing 1, a water inlet 2 is provided on the side of the housing 1, a water outlet 3 is provided at the bottom of the housing 1, and a timed dosing device 4 is arranged inside the housing 1; the timed dosing device 4 comprises a motor 41, the bottom of the motor 41 is fixedly passed through the top of the housing 1, an output shaft screw 42 of the motor 41, a stirring roller 43 is threadedly sleeved on the circumferential surface of the screw 42, a dosing port 44 is provided on the front side of the housing 1, an L-shaped baffle 412 is slidably connected to one end of the dosing port 44, one side of the L-shaped baffle 412 is located on the rotation track of the stirring roller 43, a return spring 45 is fixedly connected to the side of the L-shaped baffle 412, and a spring fixing plate 46 is fixedly connected to the end of the return spring 45 away from the L-shaped baffle 412, and the side of the spring fixing plate 46 is fixedly installed on the inner side of the housing 1. A check valve 47 is fixedly connected to one end of the water inlet 2, and the check valve 47 is located inside the housing 1. The design of the one-way valve 47 is mainly to prevent the phenomenon of water backflow through the water inlet 2 during operation. A triangular connecting plate 48 is fixedly connected to the inner wall of the box body 1, and a buffer spring 49 is fixedly connected to the side of the triangular connecting plate 48. The end of the buffer spring 49 away from the triangular connecting plate 48 is fixedly connected to a buffer plate 411. The buffer spring 49 works together with the buffer plate 411 to ensure that the water entering the water inlet 2 will contact the side of the buffer plate 411 connected to one end of the buffer spring 49, thereby preventing the sewage from directly impacting the inner wall of the box body 1 and causing damage caused by the impact.

[0020] During use, when sewage enters the interior of the box body 1 through the water inlet 2, the staff can start the motor 41 to drive the screw rod 42 fixed to the output shaft of the motor 41 to rotate, thereby driving the screw rod 42 to rotate and move up and down on the circumferential surface of the end of the motor 41 away from the stirring roller 43. When the stirring roller 43 rotates, it will contact and drive one side of the L-shaped baffle 412 sliding on one end of the dosing port 44 to move, and then drive the L-shaped baffle 412 to move. During the displacement process, the L-shaped baffle 412 will intermittently open one end of the dosing port 44, so that the purifier inside the dosing port 44 falls into the interior of the box body 1 through the dosing port 44 for purification. When the L-shaped baffle 412 is not contacted by the stirring roller 43, it will automatically rebound due to the elastic action of the reset spring 45.

[0021] See also Figure 1-4 On the basis of the first embodiment, a water inlet and outlet control device 5 is provided at one end of the water outlet 3, and a knob 51 is rotatably connected to the knob 51. A fan-shaped baffle 52 is fixedly connected to the circumferential surface of the knob 51, and an arc block 53 is fixedly connected to the top of the fan-shaped baffle 52. A rotating shaft 54 ​​is fixedly connected to the bottom of the screw rod 42, and a rotating rod 55 is fixedly connected to the bottom of the rotating shaft 54. The water inlet and outlet control device 5 is mainly used to ensure that the water outlet 3 can automatically control the switch of the water flow. One side of the arc block 53 is located on the displacement track of the rotating rod 55, and a slope is provided on the side of the arc block 53 contacting the rotating rod 55. Such a design is mainly to ensure that the rotating rod 55 better drives the arc block 53 to move during the rotation process. A limit block 56 is fixedly connected to the top of the water outlet 3, and one side of the limit block 56 is located on the displacement track of the arc block 53. The design of the limit block 56 is mainly to better block the arc block 53 during the displacement process.

[0022] During use, on the basis of the first embodiment, when the screw rod 42 rotates, it will drive the rotating shaft 54 ​​fixed at the bottom to rotate, and then drive the rotating rod 55 fixed at the bottom of the rotating shaft 54 ​​to rotate, and then drive the rotating rod 55 to touch the side of the arc block 53 fixed to the fan-shaped baffle 52 during the rotation process. Because the fan-shaped baffle 52 is fixed on the circumferential surface of the knob 51, and because the knob 51 is rotatably fixed on one end of the water outlet 3, when the rotating rod 55 contacts the arc block 53 during the rotation process, it will drive the arc block 53 to rotate, and then drive the fan-shaped baffle 52 to seal one end of the water outlet 3. When it is necessary to open one end of the water outlet 3, the motor 41 can be reversed to drive the rotating rod 55 to reverse, and then contact and drive the side of the arc block 53 away from the arc surface to move in the opposite direction. Then drive the fan-shaped baffle 52 to open one end of the water outlet 3.
