The vacuum pump is communicated with one end of the sewage discharge pipe 30 far away from the support frame 20, negative pressure is generated during working, and sewage is sucked to the sewage discharge pipe 30 from the sewage suction assembly 50 and discharged.

Specifically, the support frame 20 is provided with a connecting hole 21 and a driving hole 22, the connecting hole 21 and the driving hole 22 both penetrate through the support frame 20, and the sewage pipe 30 is connected to one side of the support frame 20 and is communicated with the connecting hole 21.

The driving assembly 40 includes a driving motor 41 and a driving gear 42, the driving motor 41 is connected to the same surface of the supporting frame 20 as the sewage pipe 30, and an output shaft of the driving motor 41 penetrates through the driving hole 22. The driving gear 42 is located on a side of the supporting frame 20 away from the driving motor 41, and is connected to an output shaft of the driving motor 41, so that when the driving motor 41 works, the driving gear 42 is driven to rotate.

The sewage suction assembly 50 comprises a sewage suction pipe 51 and a driven gear 52, a sewage suction hole 521 is formed in the driven gear 52, the driven gear 52 is rotatably connected to one surface of the support frame 20 far away from the sewage pipe 30 and meshed with the driving gear 42, and the sewage suction hole 521 is concentric with the connecting hole 21. The sewage suction pipe 51 is positioned on one surface of the driven gear 52 far away from the support frame 20, is inserted into the sewage suction hole 521 and is communicated with the sewage discharge pipe 30.

In the present embodiment, since the sewage suction pipe 51 needs to rotate together with the driven gear 52 relative to the supporting frame 20 under the driving of the driving motor 41, a space H is provided between the sewage discharge pipe 30 and the sewage suction pipe 51. When the vacuum pump works, negative pressure is generated, and dirt is sucked into the dirt suction pipe 51 under the action of the negative pressure and flows in the dirt suction pipe 51 towards the direction close to the dirt discharge pipe 30. When the dirt passes through the distance H, as long as the size at the distance H is small enough and the pressure of the negative pressure generated by the vacuum pump is large enough, the dirt can be sucked into the sewage discharge pipe 30 from the sewage suction pipe 51, so that the dirt is sucked. In some embodiments, the sewage suction pipe 51 may also be extended to be completely attached to the sewage discharge pipe 30, that is, when the sewage suction pipe 51 rotates relative to the support frame 20, a certain friction may be generated with the sewage discharge pipe 30, so as to ensure that the dirt in the sewage suction pipe 51 can be sucked into the sewage discharge pipe 30.

Further, the dirt absorbing device 10 further includes a cleaning pipe 60, and the cleaning pipe 60 is disposed around the supporting frame 20 and is communicated with an external water source to clean the dirt area by using water flow in the external water source.

Further, the quantity of delivery port 62 is three, equidistant setting on the scavenge pipe 60, and all communicate with water inlet 61 to even to the dirty region of inhaling washs.

Further, a crushing portion 511 is provided at an end of the soil suction pipe 51 away from the driven gear 52, so that the crushed soil is stirred and broken by the crushing portion 511 when the soil suction pipe 51 rotates together with the driven gear 52.

Further, the crushing part 511 is formed in a flat tooth shape to improve efficiency of crushing the filth agglomerates when rotating.

Furthermore, a connecting piece 512 is sleeved on one end, close to the driven gear 52, of the sewage suction pipe 51, and the connecting piece 512 is connected with one surface, far away from the support frame 20, of the driven gear 52 so as to reinforce the connection between the sewage suction pipe 51 and the driven gear 52.

Further, a rotating bearing is arranged between the driven gear 52 and the support frame 20 to realize the rotating connection between the driven gear and the support frame 20.

The working principle of the utility model is as follows: firstly, the driving gear 42 is driven to rotate by the driving motor 41, the driven gear 52 is driven to rotate by the meshing of the driving gear 42 and the driven gear 52, and therefore the sewage suction pipe 51 is driven to rotate by the driven gear 52, so that the agglomerated sewage is stirred and crushed. After the sewage is stirred and crushed, the vacuum pump works to generate negative pressure, the crushed sewage is sucked into the sewage suction pipe 51, moves into the sewage discharge pipe 30 from the sewage suction pipe 51 and is finally discharged from the sewage discharge pipe 30.

It will be appreciated that the vacuum pump may be operated after the dirt has been broken by agitation, or may be operated while agitating.
