Further, the present embodiment provides that the detachable tube 42 is made of an elastic material, so that the first end 421 and the second end 423 can be radially deformed when engaging with the respective tube bodies. The first end 421 and the second end 423 of the detachable tube 42 provided in this example are both detachable from the inside of the fuselage 2 independently.

The first fastening member 422 and the second fastening member 424 provided by the present embodiment are both elastic plates capable of generating deformation, and the first fastening seat 411 and the second fastening seat 431 are both elastic components capable of clamping the corresponding fastening members. In other embodiments, the first and second fastening members and the corresponding fastening seats may also be held fixedly by means of screw fit, magnetic fit, etc., and the specific fit does not limit the scope of the present invention.

The bottom of the housing 11 at the position of the detachable pipe 42 is provided with a second opening 16, and one side end of the suction pipe 41 close to the detachable pipe 42, the first fastening seat 411, the detachable pipe 42, the second fastening seat 431 and one side end of the outflow pipe 43 close to the detachable pipe 42 are all exposed from the second opening 16, so that the user can conveniently detach and install the detachable pipe 42 from the cleaning base 1. In other embodiments, a bottom cover may be removably attached to the housing at the opening to protect the components from abrasion by the surface to be cleaned.

The working principle of the surface cleaning apparatus 100 is explained below: when the surface cleaning apparatus 100 performs the cleaning operation, the solution pump, the cleaning roller motor, and the suction motor 45 are all in operation. The cleaning liquid in the solution tank 31 reaches the fluid distributor 32 along the solution path by the solution pump, and is distributed by the fluid distributor 32 onto the circumferential side of the cleaning roller 14. The rotating cleaning roller 14 cleans the surface to be cleaned with a cleaning liquid. The suction motor 45 is activated and a negative pressure is created on the fluid path from the first opening 131 to the suction motor 45. Under the action of the negative pressure, the dirty liquid at the first opening 131 is pumped and stored into the dirty liquid tank 44.

When a user needs to clean the recycling path in the cleaning base 1, the first fastening seat 411 and the second fastening seat 431 unlock the detachable tube 42, so that the detachable tube 42, the suction tube 41 and the outflow tube 43 can be cleaned, the cleanliness on the recycling path is kept, and the growth of mold is prevented.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention. All equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
