Correspondingly, a groove can be arranged in the toilet, and the broken sewage pump is quickly hung at a required position through the plug strip.

It should be noted that the above-described structure does not include only one embodiment thereof, and referring to fig. 2, as a preferred embodiment of the impeller 600, the impeller 600 is a semi-open impeller, and includes a base 610 and a plurality of blades 620, wherein an axial section of the base 610 is arc-shaped, and the blades 620 are located on the arc-shaped surface of the base and are uniformly circumferentially distributed. The cross section of the vane 620 along the radial direction of the base is arc-shaped, i.e., in the embodiment shown in fig. 7 (2), when the vane 620 rotates, the convex surfaces face the opening of the drain pipe 310, so that the dirt can be pushed out of the drain 300. Accordingly, as shown in fig. 7, other embodiments of the impeller 600 may be adopted, for example, the blades 620 are arranged straight in fig. 7 (1), or the blades 620 are arranged twisted in fig. 7 (3), the straight impeller is simple in processing, but the pushing effect is relatively poor; the twisted blades, while more prone to churning dirt, are more difficult to process and fray.

It should be noted that, since the sewage inlet pipe 100 is directly connected to the toilet stool, in some cases, there is a problem that the sewage splashes when the cutter head breaks, for example, in fig. 7 (a), the first embodiment of the sewage inlet pipe 100 is shown in the first embodiment. To avoid this problem, the dirt inlet pipe 100 needs to meet the following conditions: the soil inlet pipe 100 includes a soil inlet 101 connected to the toilet bowl and a soil outlet 102 connected to the crushing portion 200; the plane of the dirt outlet 102 is taken as a horizontal projection plane, and the front projection of the dirt inlet 101 on the horizontal projection plane is only partially overlapped with the front projection of the dirt outlet 102 on the horizontal projection plane. The orthographic projection direction and the horizontal projection plane are shown in fig. 5, and the area of the overlapping portion is shown in a hatched portion in fig. 6.

According to the above requirements, several other embodiments of the dirt inlet pipe refer to fig. 7.

For example, as shown in fig. 7 (b) and 7 (c), the dirt inlet pipe 100 is a straight pipe with a main body part having a smaller pipe diameter than the diameter of the mincing part 200, so as to avoid splashing, but this way reduces the pipe circulation efficiency;

further to avoid these problems, as shown in fig. 7 (d), the sewage inlet pipe 100 may be provided as an inclined pipe having a flat surface and a pipe diameter similar to that of the mincing part 200;

alternatively, as shown in fig. 7 (e) and 7 (f), the sewage inlet pipe 100 may be a multi-arc bent pipe, and the arc may be specifically set according to the situation, so that only the opening at the other end of the sewage inlet pipe 100 can be seen from one end of the sewage inlet pipe 100 or completely shielded.

In addition, the sewage inlet pipe 100 may be provided as a pipe having a folded angle, as shown in fig. 7 (g), so that the effect of avoiding splashing or the like is achieved, and in the actual implementation process, a certain change needs to be made to the toilet bowl according to the folded angle, and the connection mode after the change is shown in fig. 8.

It should be noted that, in the present application, the dirt inlet pipe 100 is a relatively short hard pipe, and because the dirt inlet pipe 100 is used as a dirt flow pipe and is also a pump cover of a sewage pump, the too long or too soft pipe or the pipe with relatively many connections is adopted, in the running process of the executing member, the small vibration of the sewage pump may cause loosening of the joint or reduce the service life of the pipe, and the relatively long and soft pipe is also unfavorable for the circulation of dirt, which may cause blockage in the circulation process.

To facilitate the secure mounting of the impeller 600 and the actuator, and to increase the stability of the actuator during operation. In the embodiment shown in fig. 9 and 10, the end of the accommodating case 410 near the impeller is further modified, that is, a connecting piece is additionally arranged in the connecting table to facilitate the bolting, so that the end of the output shaft of the executing piece is conveniently fixed; correspondingly, the bottom cover 420 is arranged as an inner cover and an outer cover, the inner cover is directly fixed with the bottom end of the executing piece through bolts and the like, the outer cover is installed, a gap is reserved between the inner cover and the outer cover, and redundant wires can be sealed between the inner cover and the outer cover, or glue fixation, sealing and the like are carried out between the inner cover and the outer cover. By fixing the two ends of the executing piece at the same time, the executing piece can be prevented from moving
