The portion of the scraping surface 15 between the arc-shaped end 152 and the guiding end 151 is in transition connection.

Referring to fig. 10, the guiding plate 16 is located at one side of the fan blades 132 located at the rear along the rotation direction of the rotating base 131, and the guiding plate 16 is inclined along the radial direction of the rotation axis of the rotating base 131 towards the direction away from the corresponding fan blades 132. Each fan blade 132 is provided with a through hole 1321, the through hole 1321 penetrates through the fan blade 132 along the rotation direction of the rotating base 131, one end of the guide plate 16, which is close to the fan blade 132, is located on one side of the through hole 1321, which is close to the rotating base 131, and is fixedly connected with the rotating base 131, the position of one end, which is far away from the fan blade 132, of the guide plate 16 corresponds to the position, which is close to one end of the rotating base 131, of the arc-shaped end 152 of the scraping surface 15 on the adjacent fan blade 132, and the guide plate 16 is used for guiding the liquid flowing through the through hole 1321 to the adjacent scraping surface 15.

The implementation principle of the embodiment 2 is as follows:

when the pump box 3 needs to be cleaned after being used, the control valve 81 is opened, water is introduced into the accommodating cavity 9 from the feed port 331, the motor 2 is controlled to rotate the drive shaft 21, the drive shaft 21 drives the rotating seat 131 to rotate, the rotating seat 131 drives the plurality of fan blades 132 to rotate together, the water flows into the inclined direction of the feed port 331 and impacts the fan blades 132, the fan blades 132 are favorably pushed to rotate, and the energy consumption of the motor 2 is reduced.

In the rotating process of the fan blade 132, the guiding end 151 abuts against the inner wall of the accommodating cavity 9 to scrape off the dirt deposited on the inner wall, meanwhile, the guiding end 151 can scrape off the dirt at two corners of the rotating axis of the accommodating cavity 9 along the rotating base 131 along the two opposite ends of the rotating axis of the rotating base 131, the scraped dirt is gradually gathered to the groove bottom of the guiding groove 1511 along the inner wall of the guiding groove 1511 along with the rotation of the fan blade 132, and when the fan blade 132 passes through the water outlet 8, the dirt gathered to the groove bottom of the guiding groove 1511 is flushed out of the water outlet 8 along with water flow.

Part of scraped dirt is gradually accumulated in the rotation process of the fan blade 132 and enters the scraping surface 15 along the part of the scraping surface 15 between the arc-shaped end 152 and the guide end 151, water passes through the through hole 1321 and flows along the guide plate 16 to further impact the scraping surface 15, and scraped dirt accumulated on the scraping surface 15 is favorably washed off the scraping surface 15, so that the dirt cleaning effect is better.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
