[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions in the embodiments may be combined with each other.

[0031] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0032] Embodiment 1:

[0033] Please refer to Figure 1-5 A novel dosing device comprises a first housing 1 and a second housing 2, one side of the first housing 1 is fixedly connected to the second housing 2, the upper end of the first housing 1 is fixedly connected to a first support frame 5, the upper end of the first support frame 5 is fixedly connected to a second support frame 6, the inner side of the first support frame 5 and the outer side of the second support frame 6 are rotatably connected to a ring gear 7, and the inner side of the second support frame 6 is slidably connected to a sliding frame 8, such as Figure 3 As shown, a limit rod is further provided on the inner side of the support frame 6 for sliding limit of the sliding frame 8, a plurality of connecting columns 9 are rotatably connected to the inner side of the second support frame 6 and located at the lower end of the sliding frame 8, one end of each connecting column 9 is fixedly connected to an annular column 10, each annular column 10 is fitted with the sliding frame 8, one end of each connecting column 9 away from the annular column 10 is fixedly connected to a first gear 11, each first gear 11 is meshed with the annular gear 7, a filter screen 14 is slidably connected to the inner side of the sliding frame 8, a buckle structure is provided between the filter screen 14 and the sliding frame 8, and a stirring structure is provided on the inner side of the second housing 2;

[0034] Furthermore, the outer side of the first housing 1 is respectively fixedly connected with a water inlet pipe 3 and a drain pipe 4, and the drain pipe 4 is located at the lower end of the water inlet pipe 3;

[0035] Furthermore, the upper end of the first support frame 5 is fixedly connected to a first motor 12, the output of the first motor 12 is fixedly connected to a second gear 13, and the second gear 13 is meshedly connected to the ring gear 7;

[0036] Through the above structural design, it can be known that when sewage is discharged into the water inlet pipe 3, the first motor 12 is started, and the second gear 13 is driven to rotate through the output end of the first motor 12. When the second gear 13 rotates, the second gear 13 meshes with the annular gear 7 on the inner side of the first support frame 5 and is located on the outer side of the second support frame 6 to rotate. When the annular gear 7 rotates, the annular gear 7 meshes with the first gear 11 to rotate. When the first gear 11 rotates, the first gear 11 drives the annular column 10 to rotate through the connecting column 9. When the annular column 10 rotates to fit with the sliding frame 8, the annular column 10 is rotated to fit with the sliding frame 8. The annular column 10 squeezes the sliding frame 8, so that the sliding frame 8 moves upward. When the annular column 10 rotates to no longer fit with the sliding frame 8, the sliding frame 8 moves downward by its own gravity, so that the sliding frame 8 performs longitudinal reciprocating motion, and then drives the filter screen 14 to perform longitudinal reciprocating motion through the buckle structure.
